    As a result of the transfer requirements described herein, the Auction
Rate Series 1998-1 Senior Notes will not be freely transferable, which may
limit the liquidity and marketability of Auction Rate Series 1998-1 Senior
Notes and therefore may not yield a Noteholder the best possible price for an
Auction Rate Series 1998-1 Senior Note.  The ratings of the Auction Rate
Series 1998-1 Senior Notes by the Rating Agencies will not address the market
liquidity of such Notes.

    The Series 1998-1 Notes are offered by the Underwriters subject to prior
sale, when, as and if issued to the Underwriters. The Underwriters reserve the
right to withdraw, cancel or modify such offer and to reject orders in whole
or in part. It is expected that delivery of the Series 1998-1 Notes will be
made in book-entry-only form through the Same Day Funds Settlement System of
The Depository Trust Company and also Cedel Bank, societe anonyme or the
Euroclear System on or about February 19, 1998.

    In the opinion of Bond Counsel, under existing laws, regulations, rulings

includable in the gross income of the owners thereof for federal income tax
purposes.  Interest on the Tax Exempt Series 1998-1 Notes is an item of tax
preference which is included in alternative minimum taxable income for
purposes of the federal alternative minimum tax applicable to all taxpayers,
and is includable in certain other taxes imposed upon corporations.  For a
more detailed description of the tax status of the interest on the Tax Exempt
Series 1998-1 Notes, Bond Counsel's opinion with respect thereto (including
its reliance on the Original Issuer's, SLFC's and the Corporation's compliance
with covenants made by them to satisfy certain requirements of the Internal
Revenue Code of 1986, as amended) and certain income tax consequences of Tax
Exempt Series 1998-1 Note ownership, see "Tax Matters -- Tax Exempt Series
1998-1 Notes."

The Series 1998-1 Notes may not lawfully be offered or sold to persons in the

                            REPORTS TO NOTEHOLDERS

    Monthly unaudited reports concerning the Notes and the Trust Estate (the

the Noteholders as required by the Indenture. The Series 1998-1 Notes will be
issued in book-entry form and registered in the name of Cede & Co. ("Cede &
Co."), the nominee of The Depository Trust Company, New York, New York
("DTC"). Unless and until definitive Notes are issued (which will occur under
the limited circumstances described herein) all Monthly Servicing Reports will
be provided to Cede & Co., as the sole Holder of the Notes.  The receipt by a
beneficial owner of a Series 1998-1 Note of any Monthly Servicing Report will
depend on Cede & Co. forwarding such report to the appropriate Participant or
Indirect Participant of DTC, and such Participant or Indirect Participant then
forwarding such report to the beneficial owner.  See "Description of Series
1998-1 Notes -- Book-Entry-Only System" herein.  In addition, at the request
of any beneficial owner of Series 1998-1 Notes, the Trustee will mail Monthly
Servicing Reports directly to such beneficial owner.  The Corporation will
file with the Commission such periodic reports as are required under the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules
and regulations of the Commission thereunder, and will suspend the filing of
such reports at its option if not so required.  In accordance with the
Exchange Act and such rules and regulations, the Corporation expects that its
obligation to file such reports will be terminated after June 30, 1998.

                              PROSPECTUS SUMMARY

    The following summary is qualified in its entirety by reference to the
detailed information appearing elsewhere in this Prospectus. Capitalized terms
used herein and not defined shall have the respective meanings assigned to
them under "Glossary of Certain Defined Terms" beginning on page 173 of this
Prospectus.

ISSUER                    The Series 1998-1 Notes will be issued by Education
                          Loans Incorporated, a South Dakota nonprofit
                          corporation formerly known as Student Loan Finance
                          Corporation (the "Original Issuer").  The Original
                          Issuer is a corporation described in Section 150(d)
                          of the Code.  Section 150(d) permits certain
                          nonprofit corporations (such as the Original Issuer)
                          to finance the acquisition of Student Loans made
                          under the Higher Education Act by issuing
                          obligations, the interest on which is not includable
                          in the gross income of the owners thereof for
                          federal income tax purposes.  In connection with the
                          Original Issuer's election under Section 150(d)(3)
                          of the Code to terminate its status as a corporation
                          described in Section 150(d) following the issuance
                          of the Series 1998-1 Notes, the Original Issuer will
                          issue the Series 1998-1 Notes and then immediately
                          transfer its interest in the Trust Estate (see
                          "Trust Estate" below) and be released from all
                          obligations with respect to the Notes and under the
                          Indenture.

                          Immediately following the issuance of the Series
                          1998-1 Notes, the Original Issuer will transfer all
                          of its student loans (including its rights in
                          Financed Student Loans), student loan acquisition
                          and servicing operations and physical facilities,
                          together with certain other assets (including the
                          Original Issuer's interest in the other assets
                          comprising the Trust Estate) to Student Loan Finance
                          Corporation, a newly organized South Dakota
                          corporation and wholly-owned subsidiary of the
                          Original Issuer ("SLFC"), and SLFC will assume all
                          of the Original Issuer's obligations with respect to
                          the Notes, the Indenture, the Trust Estate and all
                          related contracts.  See "The Servicer" herein.

                          Immediately upon the transfer of the Original
                          Issuer's interest in the Trust Estate to SLFC, SLFC
                          will assign such interest in the Trust Estate to
                          Education Loans Incorporated, a separate, newly
                          organized Delaware corporation (the "Corporation"),
                          which will assume all of the obligations of the
                          Original Issuer with respect to the Notes and under
                          the Indenture.  In connection with these assignments
                          and assumptions, SLFC and the Corporation will not
                          issue new Notes to the Holders of the Series 1998-1
                          Notes in exchange for those issued by the Original
                          Issuer.  Thus, the securities offered by this
                          Prospectus are obligations of the issuer under the
                          Indenture, which initially will be the Original
                          Issuer but immediately after the issuance thereof
                          will be the Corporation (and not the Original
                          Issuer).  Although the Original Issuer and the
                          Corporation initially will have the same name, they
                          are different entities.  Because all functions and
                          obligations of the issuer of the Series 1998-1 Notes
                          under the Indenture will immediately be assumed by
                          the Corporation, discussions of those functions and
                          obligations in this Prospectus generally refer to
                          the Corporation, notwithstanding that the Series
                          1998-1 Notes will actually be issued by the Original
                          Issuer.

                          Following the transfer described above, the Original
                          Issuer will have no further obligations or
                          liabilities with respect to the Notes or otherwise
                          under the Indenture.  It also will change its name
                          to Great Plains Education Foundation, Inc. and
                          continue to exist, though it will change its
                          purposes. Section 150(d)(3) of the Code requires,
                          however, that it continue to be an organization
                          described in Section 501(c)(3) of the Code.  A
                          Section 501(c) organization must be organized and
                          operated exclusively for certain purposes specified
                          in the Code, including charitable or educational
                          purposes, and

                          no part of its net earnings may inure to the benefit
                          of any private individual or shareholder. The Original
                          Issuer expects that its new purposes following the
                          transfer will be charitable or educational. See "The
                          Original Issuer", "The Corporation" and "Certain
                          Relationships Among Financing Participants" herein.

                          As of December 31, 1997, $912,425,000 aggregate
                          principal amount of the Original Issuer's bonds and
                          notes were outstanding, bearing interest at rates
                          per annum between 3.85% and 7.85%, and maturing from
                          August 1, 1998 through August 1, 2020.  A portion of
                          the proceeds of the Series 1998-1 Notes will be used
                          to refund the entire outstanding principal amount of
                          such bonds and notes, which have been issued to
                          finance the Original Issuer's Student Loan program.

TRUST ESTATE              The Trust Estate will consist of: (i) Financed
                          Student Loans, as described below, and moneys
                          payable with respect thereto after their respective
                          dates of acquisition or origination from moneys
                          under the Indenture; (ii) moneys and investment
                          securities in the Funds and Accounts held by the
                          Trustee under the Indenture; (iii) rights of the
                          Corporation in and to the Servicing Agreement, the
                          Student Loan Purchase Agreements and the Guarantee
                          Agreements, as the same relate to Financed Student
                          Loans, and (iv) the rights of the Corporation under
                          certain other related contracts.

                          Factors".  The material risks include:

                          - the limited recourse nature of the Series
                            1998-1 Notes and the limited assets
                            available for their payment

                          - the subordination of the Series 1998-1

                            Issuer for any failure to comply with

                            Direct Student Loan Program may result in
                            higher servicing costs, reduced Student Loan
                            values and higher prepayments of Financed
                            Student Loans

                            Notes without the consent of Noteholders

                            Student Loans may be insufficient to cover
                            the interest on certain Series 1998-1 Notes
                            due to differences in indexes or to borrower
                            incentive programs

                            Loan Purchase Agreements

                          - the risk that adverse regional economic
                            conditions could affect geographically
                            concentrated borrowers' ability to repay

                            may result in a loss of Special Allowance

                          shall, subject to the Senior Asset Requirement, be
                          allocated between the Taxable LIBOR Rate Series
                          1998-1 Senior Notes and the Taxable LIBOR Rate
                          Series 1998-1 Subordinate Notes pro rata.  Principal
                          of the Taxable LIBOR Rate Series 1998-1 Senior Notes
                          so allocated to be prepaid shall be applied to the
                          Series 1998-1I Notes so long as any such Notes
                          remain Outstanding, and thereafter to the Series
                          1998-1J Notes.  Within a given series of Taxable
                          LIBOR Rate Series 1998-1 Notes, the Principal Amount
                          of such series to be prepaid shall be allocated pro
                          rata to the reduction of the Principal Amount of all
                          Notes of such series.  The Senior Asset Requirement
                          requires the maintenance of certain ratios between
                          the Outstanding Principal Amounts of the Series
                          1998-1 Senior Notes and the Series 1998-1

                          Trust Estate following calls for redemption and
                          prepayments.  In general, the Senior Asset
                          Requirement requires that the Senior Percentage is
                          at least 110% and the Subordinate Percentage is at
                          least 100%, though each such percentage may be
                          lowered under the conditions prescribed in the
                          Indenture.  See "Description of Series 1998-1 Notes
                          -- Senior Asset Requirement," "Glossary of Certain
                          Defined Terms" and "Summary of the Indenture -- Call

                          The Special Prepayment Amount is an amount, as of
                          the last day of any month, equal to the excess, if
                          any, of (1) the sum of (a) all payments received as

                          Principal Amount of all Taxable LIBOR Rate Series

                          In general, this prepayment provision is intended to
                          require the Corporation to prepay Taxable LIBOR Rate
                          Series 1998-1 Notes in amounts related to the amount
                          of principal payments received with respect to

Selection of Series       If less than all Outstanding Series 1998-1 Notes are
1998-1 Notes for Call     to be called for redemption, the particular series
for Redemption            to be called for redemption will be determined by
                          the availability of particular amounts (in the case
                          of special call for redemption) or the Corporation's
                          decision to call Notes of such series for redemption
                          based upon its analysis that such redemption is in
                          the best interest of the Corporation (in the case of
                          optional call for redemption).  To the extent Series
                          1998-1 Subordinate Notes are subject to call for
                          redemption, such Notes will (unless specifically
                          provided otherwise or unless the Corporation elects
                          otherwise and provides certain required
                          certifications) be called for

                          Issuer's outstanding bond and note issues, which
                          will be refunded by the Series 1998-1 Notes. The
                          Trustee, either directly or through its affiliates,
                          has in the past entered into student loan purchase
                          agreements with the Original Issuer, including
                          Student Loan Purchase Agreements pursuant to which
                          the Original Issuer acquired Eligible Loans which
                          will be Financed under the Indenture.  The
                          Corporation expects that the Trustee will enter into
                          Student Loan Purchase Agreements providing for the
                          sale of a substantial amount of additional Eligible

                          The Higher Education Act provides that only
                          "eligible lenders" (defined to include banks and
                          certain other entities) may hold title to student
                          loans made under the Federal Family Education Loan
                          Program.  Because the Corporation does not qualify
                          as an "eligible lender," the Trustee will hold title
                          to all such Financed Student Loans on behalf of the
                          Corporation.  The Trustee will agree under the
                          Indenture to maintain its status as an "eligible
                          lender" under the Higher Education Act.

                          Corporation shall have received the necessary Rating

                          "Glossary of Certain Defined Terms."  The
                          Corporation expects that most of the Eligible Loans
                          to be acquired with the proceeds of the Series
                          1998-1 Notes will be those described in clause (A)
                          above.  Eligible Loans to be Financed with the
                          proceeds of the Tax Exempt Series 1998-1 Notes (or
                          from Balances in the Series 1998-1 Tax Exempt
                          Surplus Sub-Account) must be made to an Eligible
                          Borrower for the post-secondary education of (a) a
                          resident of the State of South Dakota attending a
                          post-secondary school located within or without the
                          State of South Dakota, or (b) a resident of a state
                          other than the State of South Dakota attending a
                          post-secondary school located within the State of
                          South Dakota.

                          Although other types of Eligible Loans may be
                          permitted to be Financed under clause (B), in
                          general, the descriptions of Eligible Loans in this
                          Prospectus (except for an immaterial amount of
                          non-Guaranteed Loans as shown herein under

                          those described in clause (A). The Corporation has
                          no current plans to acquire other Eligible Loans
                          described under clause (B) and cannot predict what
                          the terms of any such Eligible Loans might be.

                          which are not made under the Federal Family

                          Loans under clause (B) upon receiving the necessary
                          approvals from the Rating Agencies and Bond Counsel.

THE FEDERAL               The Financed Student Loans will initially consist
FAMILY                    solely of, and are expected at all times to consist
EDUCATION LOAN            primarily of, student loans originated pursuant to
PROGRAM                   the Federal Family Education Loan Program under the
                          Higher Education Act.  Pursuant to the Federal
                          Family Education Loan Program, each such Financed
                          Eligible Loan is guaranteed as to the payment of at
                          least 98% of principal and interest by a state or
                          private non-profit Guarantee Agency.  The Guarantee
                          Agencies each have reinsurance contracts with the
                          Secretary of the United States Department of
                          Education (the "Department of Education"), pursuant
                          to which the Department of Education reimburses the
                          Guarantee Agencies for such portions of guarantee
                          claims paid by the Guarantee Agencies as is provided
                          in the Higher Education Act.  In addition, the
                          Department of Education is obligated to make certain
                          interest and other subsidy payments to the holders
                          of such Financed Eligible Loans.  See "Description
                          of the Federal Family Educational Loan Program" for
                          a more complete description of the provisions of the
                          Higher Education Act that provide for such programs.
                          The obligations of the Guarantee Agencies to the
                          holders of loans, such as the Trustee, are payable
                          from the general funds available to each such
                          Guarantee Agency, including reserve funds maintained
                          by the Guarantee Agencies as required by the Higher
                          Education Act. Certain delays in receiving
                          reimbursement could occur if a Guarantee Agency
                          fails to meet its obligations.  In addition, failure
                          to properly originate or service an Eligible Loan
                          can cause an Eligible Loan to lose its guarantee
                          and/or its eligibility for federal interest payments
                          and subsidies.  See "Risk Factors -- Risk That
                          Failure to Comply with Student Loan Origination and
                          Servicing Procedures for Financed Student Loans May
                          Result in the Department of Education's Refusal to
                          Make Certain Payments to Guarantee Agencies and the
                          Trustee and the Guarantee Agencies' Refusal to Make
                          Guarantee Payments to the Trustee" and " -- Risk

STUDENT LOAN              The pool of Financed Student Loans included in the

                          "Characteristics of the Initial Financed Eligible
                          Loans."  The Corporation expects the Trustee to
                          originate and acquire additional Student Loans on
                          behalf of the Corporation, and Financed Student
                          Loans may be sold and certain events may occur with
                          respect to individual Financed Student Loans.
                          Consequently, the Student Loan Portfolio
                          characteristics are expected to change during the
                          period that the Series 1998-1 Notes are Outstanding.

INVESTMENT                The Corporation expects that the proceeds of the
AGREEMENTS                Series 1998-1 Notes that are deposited into the
                          Reserve Fund and, pending use to finance additional

                          Issuance to acquire Eligible Loans will be used to
                          acquire a series of investment agreements.  The
                          Corporation also expects that amounts deposited in
                          the Revenue Fund, the Note Fund and the Surplus Fund
                          relating to the Series 1998-1 Notes also will be

                          the Trustee (subject to such limitations as may be
                          provided therein), and to pay interest on such
                          amounts periodically.  Each Investment Provider will
                          be a party which meets the Rating Agencies' criteria
                          for creditworthiness or which has pledged collateral
                          satisfactory to the Rating Agencies to secure its
                          repayment obligations. Such investment agreements
                          will be part of the Trust Estate securing the Series
                          1998-1 Notes.

                          under the Indenture. The SLFC Servicing Agreement
                          subjects SLFC to various obligations relating to

                          that have been originated by the Original Issuer and
                          certain Eligible Loans that may be originated by the

                          such Financed Eligible Loan; (ii) the Department of
                          Education or a Guarantee Agency, as the case may be,
                          refuses to honor all or part of a claim filed with
                          respect to a Financed Eligible Loan on account of
                          any circumstance or event that occurred prior to the
                          sale of such Financed Eligible Loan to the Original
                          Issuer or to the Trustee, on behalf of the Original
                          Issuer or the Corporation, as the case may be; or
                          (iii) on account of any circumstance or event that
                          occurred prior to the sale of a Financed Eligible

                          of the Original Issuer or the Corporation, as the
                          case may be, a valid defense that makes the Financed
                          Eligible Loan unenforceable is asserted by a maker
                          (or endorser, if any) of the Financed Eligible Loan
                          with respect to his or her obligation to pay all or
                          any part of the Financed Eligible Loan.

                          The Financed Student Loans owned by the Original
                          Issuer as of the Date of Issuance, together with the
                          Original Issuer's rights under the related Student
                          Loan Purchase Agreements, will be assigned by the
                          Original Issuer and acquired by the Trustee under
                          the Indenture, without recourse or warranty.
                          Neither the Corporation, the Trustee, nor any other
                          party will have any recourse to the Original Issuer
                          in the event any Financed Student Loan should fail
                          to qualify as an Eligible Loan or in any other
                          circumstance.

                          The Indenture permits the Corporation to exchange
                          Financed Student Loans for other Eligible Loans
                          which evidence additional obligations of borrowers
                          whose Student Loans have already been Financed.

                          Reserve Fund shall not be less than the Reserve Fund
                          Requirement, which is an amount initially equal to
                          the greater of 2% of the aggregate principal amount
                          of all Notes then Outstanding or $500,000.

                          If on any Monthly Payment Date the Balance in the
                          Reserve Fund is less than the Reserve Fund
                          Requirement, the Trustee shall transfer and credit
                          thereto an amount equal to the deficiency from
                          moneys available therefor in the following Funds and
                          Accounts in the following order of priority:  the
                          Repayment Account, the Income Account and the
                          Surplus Fund.

                          The Balance in the Reserve Fund shall be used and
                          applied solely for (i) transfers to the Rebate Fund
                          to the extent necessary, after transfers thereto
                          from the Revenue Fund and the Surplus Fund (other
                          than that portion of the Balance thereof consisting
                          of Eligible Loans), to make any required deposit to
                          the Rebate Fund (see "Rebate Fund" below), and (ii)
                          after such transfer, if any, to be made pursuant to
                          the preceding clause (i) has been taken into
                          account, the payment when due of principal and
                          interest on the Senior Notes and the Subordinate
                          Notes and any Other Indenture Obligations and the
                          purchase price of Senior Notes and Subordinate Notes
                          on a Purchase Date or Mandatory Tender Date, and the
                          other purposes specified in the Indenture (see "Note
                          Fund" above).

Rebate Fund               The Indenture establishes the Rebate Fund into which
                          the Trustee is required to make annual deposits from
                          Balances in the Revenue Fund, the Surplus Fund, the
                          Reserve Fund, the Administration Fund, the Bond Fund
                          and the Acquisition Fund, in that order, equal to
                          the amount computed under Section 148(f) of the Code
                          as being subject to rebate to the United States (the
                          "Rebate Amount") and certain amounts constituting
                          Excess Earnings on the Financed Student Loans.  The
                          Trustee is required to pay to the United States
                          Treasury, at least once every five years, an amount
                          which ensures that not less than 90% of the
                          cumulative Rebate Amount will have been paid to the
                          United States Treasury.  The Trustee is required to
                          consult with Bond Counsel and take such action as
                          may be required under the Code (which may include
                          forgiveness of principal of Financed Student Loans
                          or payments to the United States Treasury) with
                          respect to Excess Earnings.  Under certain
                          circumstances, including delivery to the Trustee of
                          a favorable opinion of Bond Counsel, certain amounts
                          determined not to be subject to rebate or other
                          disposition may be transferred from the Rebate Fund
                          to the Income Account.

Surplus Fund              The Indenture establishes a Surplus Fund comprised
                          of two Accounts:  the Special Redemption and
                          Prepayment Account and the Surplus Account.  The
                          Trustee shall deposit to the credit of the Surplus
                          Fund Balances in the Revenue Fund not required for
                          deposit to any other Fund or Account. Deposits to
                          the Surplus Fund from the Revenue Fund shall be
                          credited to the Special Redemption and Prepayment
                          Account to the extent the Balance thereof is less
                          than the Special Redemption and Prepayment Account
                          Requirement for each series of Notes, and otherwise
                          to the Surplus Account.

                          Balances in the Surplus Fund shall be used first to
                          make up deficiencies in, or make required transfers
                          to, the Rebate Fund, the Note Fund, the
                          Administration Fund and the Reserve Fund.  Balances
                          in the Surplus Fund may also be applied, as
                          determined by the Corporation from time to time, to
                          the payment of principal of or interest on Class C
                          Notes when due or upon the call thereof for
                          redemption at the option of the Corporation, subject
                          to meeting certain conditions described in "Summary
                          of the Indenture -- Funds and Accounts -- Surplus
                          Fund" are met.

                          If the Trustee shall have first certified that no
                          deficiencies exist in any of the Rebate Fund, the
                          Note Fund, the Reserve Fund or the Special
                          Redemption and Prepayment Account, and shall have
                          received certain certifications from the
                          Corporation, Balances in the Surplus Account may be
                          used to redeem Notes which are called for redemption
                          (including Series 1998-1 Notes as described under

                          any such application (i) the Senior Percentage will
                          be not less than 112%, and (ii) the Subordinate
                          Percentage will be not less than 102%; provided that
                          such percentages may be lower upon receipt of
                          certain approvals from each Rating Agency and, under
                          certain circumstances, consent of Other
                          Beneficiaries.

                          Balances in the Special Redemption and Prepayment
                          Account may be transferred to the credit of the

                          Subordinate Notes which are called for redemption or
                          to prepay Senior Notes or Subordinate Notes as
                          provided in a Supplemental Indenture relating
                          thereto (provision for which, in the case of the

ADDITIONAL PARITY         The Corporation may, upon complying with the
NOTES                     provisions of the Indenture, issue from time to time
                          Additional Notes or incur certain other Indenture
                          Obligations secured by the Trust Estate on a parity
                          with or subordinate to the Senior Notes.  Any
                          Additional Notes will not be offered or sold
                          pursuant to this Prospectus.  See "Summary of the
                          Indenture" herein.

SUBORDINATION             The rights of the Series 1998-1 Subordinate
                          Noteholders to receive payments with respect to the
                          Notes will be subordinated to such rights of the
                          Series 1998-1 Senior Noteholders and any other
                          Senior Beneficiaries to the extent described in this
                          Prospectus.  This subordination is intended to
                          enhance the likelihood of timely receipt by the
                          Series 1998-1 Senior Noteholders of the full amount
                          of scheduled payments of principal and interest due
                          them.  Thus, payments of interest and principal on
                          the Series 1998-1 Subordinate Notes will be made
                          when due (on a parity basis with any other
                          Subordinate Obligations) only to the extent there
                          are sufficient monies available for such payment,
                          after making all payments due on such date with
                          respect to the Senior Obligations.  So long as
                          Senior Obligations remain Outstanding under the
                          Indenture, the failure to make interest or principal
                          payments on the Series 1998-1 Subordinate Notes will
                          not constitute an Event of Default under the
                          Indenture.  Payments of principal and interest on
                          the Series 1998-1 Subordinate Notes would be
                          similarly subordinated to Senior Obligations if the
                          Notes were accelerated because of an Event of
                          Default.

                          The Series 1998-1 Subordinate Notes are also
                          subordinated to the Series 1998-1 Senior Notes and
                          any other Senior Obligations as to the direction of
                          remedies upon default.


FEDERAL INCOME            In the opinion of Dorsey & Whitney LLP, the Series
TAX TREATMENT OF          1998-1 Notes will be treated as debt of the Original
SERIES 1998-1 NOTES       Issuer (and upon the assumption by the Corporation
                          of the Original Issuer's obligations under the
                          Indenture, as debt of the Corporation), rather than
                          as an interest in the Financed Student Loans and
                          other Trust Estate assets, for federal income tax
                          purposes.  As such, the owners of the Taxable Series
                          1998-1 Notes will be required to include in income
                          interest on such Taxable Series 1998-1 Notes as paid
                          or accrued, in accordance with their respective
                          accounting methods and the provisions of the Code.
                          See "Tax Matters -- Federal Income Tax
                          Consequences".

EXCLUSION OF              In the opinion of Dorsey & Whitney LLP, as Bond
INTEREST ON TAX           Counsel, under existing laws, regulations, rulings
EXEMPT SERIES             and decisions, interest on the Tax Exempt Series
1998-1 NOTES              1998-1 Notes is not includable in the gross income
FROM GROSS INCOME         of the owners thereof for federal income tax
                          purposes.  Interest on the Tax Exempt Series 1998-1
                          Notes is an item of tax preference which is included
                          in alternative minimum taxable income for purposes

                                 RISK FACTORS

    Prospective investors should consider, among other things, the following
factors regarding the purchase of the Series 1998-1 Notes.

THE SERIES 1998-1 NOTES ARE LIMITED RECOURSE OBLIGATIONS AND LIMITED ASSETS OF
THE CORPORATION ARE AVAILABLE FOR THE PAYMENT OF THE SERIES 1998-1 NOTES

    The Corporation is a special purpose corporation and the Series 1998-1
Notes will represent obligations solely of the Corporation.  The Series 1998-1
Notes are not insured or guaranteed by any government agency or
instrumentality, by any affiliate of the Corporation, by any insurance company
or by any other person or entity.  The Corporation will have no significant
assets available to make payment on the Series 1998-1 Notes other than the
Trust Estate pledged as collateral for the Notes under the Indenture.
Moreover, the Series 1998-1 Notes are limited obligations of the Corporation,
payable solely from the Trust Estate and not from any other assets which the
Corporation may have or any other revenues to which the Corporation may be
entitled.  The Trust Estate will not have, nor is it expected to have, any
significant assets or sources of funds other than the Financed Student Loans,
the Acquisition Fund, the Reserve Fund and the other Funds and Accounts.
Payments on the Series 1998-1 Notes will depend solely on the amount and
timing of payments and collections in respect of the Financed Student Loans,
investment earnings on the various Funds and Accounts established pursuant to
the Indenture, amounts on deposit in the Reserve Fund and the other Funds and
Accounts, and the payment priority of the Series 1998-1 Notes, any Additional
Notes to be issued in the future and any credit enhancement obtained with
respect to such Additional Notes.  (Any Additional Notes will not be offered
or sold pursuant to this Prospectus.)  There will be no additional recourse to
the Corporation or any other person if such proceeds are insufficient.  As a
result, Noteholders must depend on the cash flow with respect to the Financed
Student Loans and funds on deposit in the Acquisition Fund, the Reserve Fund
and the other Funds and Accounts for payment of principal of and interest on
the Series 1998-1 Notes.

HOLDERS OF THE SERIES 1998-1 SUBORDINATE NOTES ARE SUBORDINATE IN PAYMENT
PRIORITY AND AS TO THE DIRECTION OF REMEDIES

    Payments of principal of and interest on the Series 1998-1 Subordinate
Notes are subordinated in priority of payment to payments of principal of and
interest on the Series 1998-1 Senior Notes and any other Senior Obligations
that may be outstanding from time to time.  See "Source of Payment and
Security for the Notes".  The Series 1998-1 Subordinate Notes are also
subordinated to the Series 1998-1 Senior Notes and any other Senior
Obligations as to the direction of remedies upon an Event of Default.

FAILURE TO COMPLY WITH STUDENT LOAN ORIGINATION AND SERVICING PROCEDURES FOR
FINANCED STUDENT LOANS MAY RESULT IN THE DEPARTMENT OF EDUCATION'S REFUSAL TO
MAKE CERTAIN PAYMENTS TO GUARANTEE AGENCIES AND THE TRUSTEE AND THE GUARANTEE
AGENCIES' REFUSAL TO MAKE GUARANTEE PAYMENTS TO THE TRUSTEE

    The Higher Education Act requires lenders and their agents making and
servicing student loans under the Federal Family Education Loan Program and
Guarantee Agencies guaranteeing such student loans to follow specified
procedures, including due diligence procedures, to ensure that such student
loans are properly originated, disbursed and collected.  Certain of those
procedures, which are specifically set forth in the Higher Education Act, are
summarized herein.  See "Description of Financed Eligible Loan Program" and
"Description of the Federal Family Education Loan Program."  Generally, those
procedures require that completed loan applications be processed, a
determination of whether an applicant is an eligible borrower under the Higher
Education Act be made, the borrower's responsibilities under the loan be
explained to him or her, the promissory note evidencing the loan be executed
by the borrower and the loan proceeds be disbursed by the lender in a
specified manner.  After the loan is made, the lender must establish repayment
terms with the borrower, properly administer deferments and forbearances and
credit the borrower for payments made.  If a borrower becomes delinquent in
repaying a loan, a lender must perform certain collection procedures
(including numerous telephone calls and demand letters, skip-

                                      -32-
<PAGE>
 
tracing procedures, and requesting assistance from the applicable Guarantee
Agency) which vary depending upon the length of time a loan is delinquent.

    The Corporation believes that the Original Issuer has followed these
procedures in its acquisition, servicing and collection of the Eligible Loans
to be Financed.  In addition, SLFC will agree in the SLFC Servicing Agreement
to perform origination, servicing and collection procedures on behalf of the
Trustee and the Corporation in compliance with those procedures.  However,
failure of the Original Issuer to have followed these procedures with respect
to the existing Student Loan Portfolio, failure of SLFC or any successor
Servicer to follow these procedures or failure of any Lender or any other
originator or Servicer of the Financed Student Loans to have followed or to
follow these procedures with respect to any Financed Student Loans may result
in the Department of Education's refusal to make reinsurance payments to the
Guarantee Agencies or to make Special Allowance Payments or Interest Subsidy
Payments to the Trustee with respect to such Financed Student Loans or in the
Guarantee Agencies' refusal to make payments under their Guarantee Agreements
with the Trustee ("Guarantee Payments") with respect to such Financed Student
Loans.  Failure of the Guarantee Agencies to receive reinsurance payments from
the Department of Education could adversely affect the Guarantee Agencies'
ability or legal obligation to make Guarantee Payments to the Trustee.  Loss
of any such Guarantee Payments, Special Allowance Payments or Interest Subsidy
Payments with respect to Financed Student Loans could adversely affect the
amount of revenues under the Indenture and the Corporation's ability to pay
principal of and interest on the Series 1998-1 Notes.  See "Description of the
Federal Family Education Loan Program."

NO RECOURSE EXISTS AGAINST THE ORIGINAL ISSUER FOR ANY FAILURES TO COMPLY WITH
ORIGINATION AND SERVICING PROCEDURES RELATING TO THE FINANCED STUDENT LOANS

    The transfer of the original portfolio of Financed Student Loans from the
Original Issuer to the Trustee is without recourse.  Neither the Corporation
nor the Trustee will have any right to resell the Financed Student Loans to
the Original Issuer or otherwise to make recourse to or collect from the
Original Issuer if such Financed Student Loans should fail to meet the
requirements of an Eligible Loan for any reason or if such transfer should
fail to provide the Trustee with good title to such Financed Student Loans.

    The failure of any Financed Student Loan to conform to all of the
requirements of the Higher Education Act or the Guarantee Agencies with
respect thereto could result in the loss of the Trustee's right to receive
Guarantee Payments, Special Allowance Payments, and/or Interest Subsidy
Payments with respect to such Financed Student Loan.

CHANGES IN LAW COULD ADVERSELY AFFECT THE FEDERAL FAMILY EDUCATION LOAN
PROGRAM AND THE FINANCED STUDENT LOANS

    There can be no assurance that the Higher Education Act or other relevant
federal or state laws, rules and regulations and the programs implemented
thereunder will not be amended or modified in the future in a manner that will
adversely impact the programs described herein and the loans made thereunder,
including the Financed Student Loans or the Guarantee Agencies. The Federal
Family Education Loan Program has been the subject of numerous amendments and
proposed amendments to the Higher Education Act, including amendments designed
to reduce the federal budget deficit.  Amendments to the Higher Education Act
in the past several years have reduced the portion of loans covered by
Guarantee Payments and the portion of Guarantee Payments covered by
reinsurance, reduced certain administrative expense allowances paid by the
Department of Education to Guarantee Agencies, reduced the premiums and
default collections that Guarantee Agencies are entitled to receive and/or
retain, and given the Department of Education broad powers over Guarantee
Agencies and their reserves, including the authority to require a Guarantee
Agency to pay a portion or all reserve funds to the Department of Education in
certain circumstances.

                                      -33-
<PAGE>
 
    Several proposals have been made by Congress and the Administration to
amend the Higher Education Act, including proposals that would significantly
alter the Federal Family Education Loan Program and the roles of its
participants.  It is impossible to predict whether any such proposals will be
adopted as legislation or, if so, what impact such legislation may have on the
Corporation's or Trustee's receipt of revenues with respect to Financed
Student Loans.

THE COMPETING FEDERAL DIRECT STUDENT LOAN PROGRAM MAY RESULT IN HIGHER
SERVICER COSTS BECAUSE OF REDUCED ECONOMIES OF SCALE; A SMALLER SECONDARY
MARKET AND REDUCED VALUE FOR FINANCED STUDENT LOANS; AND HIGHER PREPAYMENTS OF
FINANCED STUDENT LOANS THROUGH CONSOLIDATIONS

    The Higher Education Act provides for a Federal Direct Student Loan
Program.  This program, established in academic year 1994-1995, has a
statutory target volume of 60% of student loan demand in academic year
1998-1999, which could result in reductions in the volume of loans made under
the Federal Family Education Loan Program.  As the Federal Direct Student Loan
Program expands, the Servicer may experience increased costs due to reduced
economies of scale to the extent the volume of new loans serviced by the
Servicer is reduced.  Such cost increases could affect the ability of the
Servicer to satisfy its obligations to service the Financed Eligible Loans.
Such volume reductions could also reduce revenues received by the Guarantee
Agencies available to pay claims on defaulted Eligible Loans.  Finally, the
level of competition currently in existence in the secondary market for loans
made under the Federal Family Education Loan Program could be reduced,
resulting in fewer potential buyers of the Eligible Loans and lower prices
available in the secondary market for those loans.  Further, the Department of
Education has implemented a direct consolidation loan program, which program
may further reduce the volume of loans made under the Federal Family Education
Loan Program and is expected to result in prepayments of Financed Student
Loans.  See "Description of the Federal Family Education Loan Program."

ADDITIONAL NOTES MAY BE ISSUED WITHOUT NOTEHOLDER CONSENT

    The Corporation may, from time to time pursuant to the provisions of the
Indenture, issue Additional Notes or incur other Indenture Obligations secured
by the Trust Estate on a parity with or subordinate to the Series 1998-1
Senior Notes and senior to, on a parity with or subordinate to the Series
1998-1 Subordinate Notes, as determined by the Corporation, without the
consent or approval of the Holders of any Notes then Outstanding.  While the
Indenture requires that the Corporation satisfy certain conditions, including,
but not limited to, the condition that the issuance of the Additional Notes
will not adversely affect the ratings on the then outstanding Notes, if
Additional Notes are issued and the Financed Student Loans acquired with the
proceeds of such Additional Notes do not produce sufficient revenue to pay
principal of and interest on those Additional Notes, it may result in a delay
in or reduction of payments on the Series 1998-1 Notes.  Moreover, if
Additional Notes are issued and an Event of Default occurs with respect to
such Additional Notes and such Event of Default is not cured or waived, then
all Notes which are then outstanding, including the Series 1998-1 Notes, are
subject to acceleration.  Any Additional Notes will not be offered or sold
pursuant to this Prospectus.  This Prospectus relates only to the Series
1998-1 Notes.  See "Additional Notes" herein.

THE INTEREST RATES ON FINANCED STUDENT LOANS AND OTHER INVESTMENTS MAY BE
INSUFFICIENT TO COVER INTEREST ON THE SERIES 1998-1 NOTES (OTHER THAN TAX
EXEMPT FIXED RATE SERIES 1998-1 SENIOR NOTES AND TAX EXEMPT FIXED RATE SERIES
1998-1 SUBORDINATE NOTES) DUE TO RATE-INDEX DIFFERENCE

    The interest rates with respect to the Series 1998-1 Notes (other than the
Tax Exempt Fixed Rate Series 1998-1 Senior Notes and the Tax Exempt Fixed Rate
Series 1998-1 Subordinate Notes) may fluctuate from one interest period to
another in response to changes in benchmark rates or general market
conditions.  The Corporation can make no representation as to what such rates
may be in the future.  The interest rates on each series of Auction Rate
Series 1998-1 Senior Notes will be based generally on the outcome of each
Auction of such series of Notes.  The interest rates on each series of Taxable
LIBOR Rate Series 1998-1 Notes will be based generally on One-Month LIBOR. The
Financed Student Loans, however, generally bear interest at an effective rate
(taking into account any Special Allowance Payments, the "Loan Rates") equal
to the average bond equivalent rates of weekly auctions of

                                      -34-
<PAGE>
 
91-day Treasury bills for each quarter (the "91-day Treasury Bill Rate") (or,
in certain circumstances, 52-week Treasury bills) plus margins specified for
such Financed Student Loans. See "Description of the Federal Family Education
Loan Program - - Loan Terms -- Interest Rates" and " -- Federal Special
Allowance Payments."  As a result of these differences between the indices
used to determine the Loan Rates and the interest rates on the variable rate
Series 1998-1 Notes, there could be periods of time when the Loan Rates are
inadequate to cover the interest on the Series 1998-1 Notes and expenses
required under the Indenture. Moreover, the Net Loan Rate will be determined
as of a date as much as two months prior to the determination of the rates
borne by the variable rate Taxable Series 1998-1 Notes.  Thus, in a period of
rapidly rising interest rates, the Net Loan Rate may not increase as quickly
as the variable interest rates with respect to the Taxable Series 1998-1
Notes.  To the extent that the Loan Rates decrease or do not increase as fast
as the variable interest rates with respect to the Taxable Series 1998-1
Notes, the interest rates with respect to such Taxable Series 1998-1 Notes may
be limited to the Net Loan Rate or may be deferred to future periods.  There
can be no assurance that sufficient funds will be available in future periods
to make up for any shortfalls in the current payments of interest on the
Taxable Series 1998-1 Notes.  Further, if there is a decline in the Loan
Rates, the amount of funds representing interest deposited into the Trust
Estate may be reduced and, even if there is a similar reduction in the
variable interest rates applicable to any series of Series 1998-1 Notes, there
may not necessarily be a similar reduction in the other amounts required to be
funded out of such funds (such as certain administrative expenses).  In
addition, proceeds of and revenues relating to the Series 1998-1 Notes in the
Reserve Fund, the Acquisition Fund, the Revenue Fund, the Note Fund and the
Surplus Fund will be used to acquire investment agreements at fluctuating
interest rates.  Although the Corporation will structure such investment
agreements to minimize such risk, there can be no assurance that the interest
rates on such investment agreements will keep pace with the fluctuating
interest rates on the Series 1998-1 Notes.

CHANGES IN REPAYMENT TERMS OF FINANCED STUDENT LOANS PURSUANT TO INCENTIVE
PROGRAM.

    The Original Issuer currently makes available and the Corporation may
hereafter make available certain incentive programs to borrowers.  It cannot
be predicted with certainty how many borrowers will qualify or decide to
participate in these programs.  The effect of these incentive programs may be
to reduce the yield on the Financed Student Loans.  Reductions in the yield on
the Financed Student Loans resulting from such incentive programs will result
in a reduction of the Net Loan Rate.  There is no assurance that the Net Loan
Rate (and thus the interest rate on the Taxable Series 1998-1 Notes) will not
be reduced below the rates that would otherwise be borne by such Notes.

CHANGES IN THE ASSETS OF THE TRUST ESTATE, INCLUDING FUTURE FUNDING OF STUDENT
LOANS, CHANGING CHARACTERISTICS OF FINANCED STUDENT LOANS, FINANCED ELIGIBLE
LOANS THAT ARE NOT MADE UNDER THE FEDERAL FAMILY EDUCATION LOAN PROGRAM AND
FINANCED STUDENT LOANS THAT ARE NOT ELIGIBLE LOANS IN THE SURPLUS ACCOUNT

    The initial Student Loan Portfolio to be Financed on the Date of Issuance
with a portion of the proceeds of the Series 1998-1 Notes is described herein
under "Characteristics of the Initial Financed Eligible Loans."  The
investment agreements which will be acquired on the Date of Issuance with the
remaining proceeds of the Series 1998-1 Notes are described herein under
"Application of Series 1998-1 Note Proceeds."  After the Date of Issuance, the
Corporation intends to cause the Trustee to purchase Financed Eligible Loans
from Lenders and to originate Eligible Loans from amounts initially deposited
in the Acquisition Fund and used to acquire such investment agreements (upon
repayment of such amounts pursuant to such investment agreements).  The actual
characteristics of the Student Loan Portfolio will change from time to time
due to factors such as adjustments made in the normal course of business,
amendments to the Higher Education Act, changes in the classifications of
Eligible Loans, sales or exchanges of Eligible Loans by the Trustee on behalf
of the Corporation, scheduled amortization, prepayment or the occurrence of
delinquencies or defaults.  In addition, the Indenture allows the Corporation
to apply balances in the Surplus Account to the acquisition of Student Loans
that do not qualify as Eligible Loans.  See "Summary of the Indenture - Funds
and Accounts - Surplus Fund."  Moreover, though all Financed Eligible Loans
will initially be loans made under the Federal Family Education Loan Program,
Eligible Loans that are not made under such

                                      -35-
<PAGE>
 
program may be Financed in the future and such other Eligible Loans may have
different features and be of lesser credit quality.  Among possible
differences, such loans may be Guaranteed at lesser reimbursement rates by the
Guarantee Agencies, may be insured by private entities or uninsured, may have
different interest rates and repayment terms, and may not have any third party
subsidies.  If Student Loans are Financed which are not Eligible Loans
(whether or not made under the Federal Family Education Loan Program), they
may have no third party guarantee or eligibility for interest subsidies and
Special Allowance Payments, and thus may bear a lower rate of return and a
greater risk of loss from borrower default in payment.

RELIANCE UPON LENDERS' REPRESENTATIONS AND WARRANTIES RELATING TO FINANCED
STUDENT LOANS WITHOUT CONDUCTING COMPLETE INDIVIDUAL STUDENT LOAN DOCUMENT
EXAMINATIONS

    The Original Issuer has acquired the majority of the initial Student Loan
Portfolio, and the Corporation expects to cause the Trustee to acquire
additional Financed Eligible Loans, from Lenders pursuant to Student Loan
Purchase Agreements under which each Lender has agreed or will agree to sell
to the Original Issuer or to the Trustee, on behalf of the Corporation,
Eligible Loans which comply with certain representations and warranties.  The
Student Loan Purchase Agreements provide for the repurchase by the Lender of
Financed Student Loans that do not comply with such representations and
warranties.  However, neither the Original Issuer, SLFC nor the Corporation
has conducted or will conduct an examination of documents relating to the
Eligible Loans to be Financed of sufficient scope to determine whether the
Lenders who have sold such Eligible Loans to the Original Issuer, or will sell
such Eligible Loans to the Trustee on behalf of the Corporation, have met or
will have met all the conditions of the Higher Education Act necessary for
such loans to qualify for Guarantee Payments from the applicable Guarantee
Agency.  Moreover, no assurance can be given that any Lender will honor, or be
able to honor, its obligations to sell Eligible Loans to the Trustee or to
repurchase non-conforming Student Loans, or that the Trustee would be able to
acquire Eligible Loans in an equivalent amount, with similar characteristics
or at comparable prices from other sources in the event that any Lenders fail
to sell Eligible Loans to the Trustee or are required to repurchase Financed
Student Loans.

INABILITY OF LENDERS TO HONOR THEIR OBLIGATIONS TO REPURCHASE FINANCED STUDENT
LOANS

    Under the circumstances set forth in the Student Loan Purchase Agreements,
a Lender may be obligated to repurchase Financed Student Loans from the
Trustee. If a Lender were to become insolvent or otherwise be unable to
repurchase such Financed Student Loans, it is unlikely that a repurchase of
such Financed Student Loan from the Trustee would occur.  The failure of such
a Lender to repurchase a Financed Student Loan would constitute a breach of
the respective Student Loan Purchase Agreement, enforceable by the Trustee,
but would not constitute an Event of Default under the Indenture or permit the
exercise of remedies thereunder.

GEOGRAPHICALLY CONCENTRATED BORROWERS MAY BE SUBJECT TO REGIONAL ECONOMIC
CONDITIONS THAT ADVERSELY AFFECT THEIR ABILITY TO REPAY STUDENT LOANS

    Although the Original Issuer has not experienced any geographical risks,
it is possible that geographically concentrated borrowers will be subject to
economic risks specific to their region which could adversely affect their
ability to repay Student Loans.  See "Characteristics of the Initial Financed
Eligible Loans -- Distribution of Financed Eligible Loans by Borrowers'
Address as of December 31, 1997 (Based on Address as of January 9, 1998)."

POSSIBLE LOSS OF TAX EXEMPTION OF THE INTEREST ON THE TAX EXEMPT SERIES 1998-1
NOTES

    Provisions of the Code impose continuing requirements that must be met
after the issuance of the Tax Exempt Series 1998-1 Notes for interest thereon
to be and remain excludable from gross income for federal income tax purposes.
Noncompliance with such requirements may cause the interest on the Tax Exempt
Series 1998-1 Notes to be includable in gross income for such purposes, either
prospectively or retroactively to the date of issuance of the Tax Exempt
Series 1998-1 Notes. These requirements include, but are not limited to,
provisions that prescribe that the proceeds of the Tax Exempt Series 1998-1
Notes and certain other amounts are subject to yield

                                      -36-
<PAGE>
 
and other investment limits and provisions that require that certain
investment earnings be rebated on a periodic basis to the Treasury Department
of the United States.  These provisions limit the return to which the
Corporation is entitled from investments allocable to the Tax Exempt Series
1998-1 Notes (1) in the case of Student Loans, generally to 2% in excess of
the yield on the Tax Exempt Series 1998-1 Notes, and (2) in the case of other
investments, generally to the yield on the Tax Exempt Series 1998-1 Notes.  To
the extent such investments are permitted to, and do, produce a yield in
excess of such limitations, such excess would generally be required to be
rebated to the Treasury Department every five years.

    In addition, Section 150(d)(3) of the Code contains numerous provisions
that must be complied with at and after the time an election under such
section is made for interest on the Tax Exempt Series 1998-1 Notes to be and
remain excludable from gross income.  Although the Original Issuer and the
Corporation believe that the issuance of the Series 1998-1 Notes, the
organization of SLFC and the Corporation, and the transfers of assets and
assumptions of obligations described herein under "The Original Issuer" and
"The Corporation" will comply with the requirements of Section 150(d)(3) of
the Code, no determination has been obtained or is expected to be sought from
the Internal Revenue Service with respect to such compliance. Moreover, the
Original Issuer believes that it will be the first entity to make the election
provided for in Section 150(d)(3) of the Code, and no established practices
have developed nor have any regulations or other guidance been published by
the Internal Revenue Service.

    It is possible that future action or inaction by the Corporation, SLFC or
the Original Issuer could cause the inclusion of interest on the Tax Exempt
Series 1998-1 Notes in gross income for federal income tax purposes (in some
cases retroactively to the date of their original issuance).  In such event,
it is probable that certain (and possibly all) of the interest payments
received by owners of Tax Exempt Series 1998-1 Notes would be subject to
Federal income taxes, thereby having the effect of reducing (possibly
substantially) the effective, after-tax yield on their investment in the Tax
Exempt Series 1998-1 Notes.

INSOLVENCY OF THE ORIGINAL ISSUER, SLFC OR THE CORPORATION

    The Corporation has taken steps in structuring the transactions
contemplated hereby that are intended to ensure that the voluntary or
involuntary application for relief by the Original Issuer or SLFC under the
United States Bankruptcy Code or other insolvency laws, as the case may be
("Insolvency Laws"), will not result in consolidation of the assets and
liabilities of the Corporation with those of the Original Issuer and/or SLFC.
These steps include the creation of the Corporation as a separate,
limited-purpose subsidiary of SLFC pursuant to a certificate of incorporation
containing certain limitations (including restrictions on the nature of the
Corporation's business and a restriction on the Corporation's ability to
commence a voluntary case or proceeding under any Insolvency Law without the
prior unanimous affirmative vote of all of its directors, including at least
two directors who must be independent of the Corporation and its affiliates).
However, there can be no assurance that the activities of the Corporation
would not result in a court concluding that the assets and liabilities of the
Corporation should be consolidated with those of the Original Issuer or SLFC
in a proceeding under any Insolvency Law.  If a court were to reach such a
conclusion or if a filing were made under any Insolvency Law by or against the
Corporation, or if an attempt were made to litigate any of the foregoing
issues, then delays in payments on the Notes could occur or reductions in the
amounts of such payments could result.  See "The Original Issuer", "The
Corporation" and "Certain Relationships Among Financing Participants."

    The Original Issuer will transfer all of its rights and interest in and to
the Financed Student Loans (subject to the lien of the Trustee under the
Indenture) to SLFC, and SLFC will in turn transfer all such rights and
interest in and to the Financed Student Loans to the Corporation.

    The Original Issuer intends that its transfer of the Financed Student
Loans to SLFC constitute a sale of all of the Original Issuer's rights in such
Financed Student Loans (subject to the lien of the Trustee under the
Indenture), rather than a pledge to secure indebtedness.  Similarly, SLFC
intends that its transfer of the Financed Student Loans to the Corporation
constitute a sale of all of SLFC's rights in such Financed Student Loans,
rather than a pledge to secure indebtedness.  Dorsey & Whitney LLP, counsel to
the Original Issuer and SLFC, will

                                      -37-
<PAGE>
 
deliver a legal opinion of the effect that, subject to the qualifications and
limitations expressed therein, the transfers of the Financed Student Loans
from the Original Issuer to SLFC and from SLFC to the Corporation each
constitute a true sale, rather than a pledge to secure indebtedness, and that
the Financed Student Loans would not be considered property of the Original
Issuer or SLFC should either entity thereafter become subject to any
Insolvency Law.

    If, however, the Original Issuer or SLFC were to become subject to any
Insolvency Law and a creditor or trustee-in- bankruptcy of the Original Issuer
or SLFC were to take the position that the sale of the Financed Student Loans
by the Original Issuer to SLFC or by SLFC to the Corporation, as appropriate,
should instead be treated as a pledge of such interest to secure a borrowing
from SLFC or the Corporation, as appropriate, delays in payments on the Notes
from collections on Financed Student Loans could occur or (should the court
rule in favor of the Original Issuer or SLFC, as appropriate, or such
creditor) reductions in the amounts of such payments could result.

    Upon the occurrence of any of certain events of bankruptcy or insolvency
with respect to the Corporation, the Financed Student Loans may be liquidated.
The proceeds from any such liquidation of Financed Student Loans would be
treated as collections on the Financed Student Loans and deposited in the
Revenue Fund.  There can be no assurance that the proceeds from the
liquidation of the Financed Student Loans and amounts (if any) on deposit in
the Reserve Fund and the other Funds and Accounts held under the Indenture
would be sufficient to pay the Notes in full.  See "Summary of the
Indenture-Events of Default."

    As the Servicer of the Financed Student Loans, the insolvency of SLFC may
result in a disruption in the servicing of the Financed Student Loans and the
receipt of payments with respect thereto, and also may result in a failure to
comply with servicing requirements of the Department of Education and the
Guarantee Agencies.

FAILURE TO COMPLY WITH THE ORIGINAL ISSUER'S PLAN FOR DOING BUSINESS MAY
RESULT IN THE DEPARTMENT OF EDUCATION REFUSING TO MAKE SPECIAL ALLOWANCE
PAYMENTS WITH RESPECT TO FINANCED STUDENT LOANS OR SEEKING TO BE REIMBURSED
FOR PRIOR SPECIAL ALLOWANCE PAYMENTS

    The Higher Education Act provides that, for holders of Federal Family
Education Loan Program loans that are financed with tax exempt debt to be
eligible for Special Allowance Payments with respect to such loans, the issuer
of the debt must adopt, obtain approval of, and comply with, a plan for doing
business meeting the requirements of the Higher Education Act. The Original
Issuer has adopted, and the Governor of the State of South Dakota has
approved, such a plan.  Because the Original Issuer expects to terminate its
participation in the Federal Family Education Loan Program, the Original
Issuer will no longer be capable of carrying out certain provisions of such
plan for doing business.  The Original Issuer, SLFC, and the Corporation will
each covenant to comply with the provisions of such plan for doing business
that apply to their respective operations.  However, if any such party fails
to comply with such provisions of the plan for doing business, or if the
Original Issuer failed to comply in the past with all provisions of its plan
for doing business, or if the Department of Education determines that the
Original Issuer's plan for doing business or the reallocation of
responsibilities thereunder in connection with the Original Issuer's election
under Section 150(d)(3) of the Code does not comply with the Higher Education
Act, Financed Student Loans could lose their eligibility for Special Allowance
Payments and the Original Issuer, the Corporation and/or the Trustee may be
required to repay Special Allowance Payments theretofore made to the Original
Issuer or the  Trustee with respect to Financed Student Loans.  Depending on
the amount involved, loss of Special Allowance Payments or required repayment
of Special Allowance Payments could have a materially adverse affect on the
Corporation's ability to pay the principal of and interest on the Series
1998-1 Notes.

USE OF A SHARED LENDER IDENTIFICATION NUMBER MAY RESULT IN THE GUARANTEE
AGENCIES AND THE DEPARTMENT OF EDUCATION OFFSETTING AGAINST GUARANTEE PAYMENTS
AND OTHER FEDERAL BENEFIT PAYMENTS OWED TO THE TRUSTEE

    Due to Department of Education policy limiting the granting of new lender
identification numbers, the Indenture will allow the Trustee, if necessary, to
use the Department of Education lender identification number that it uses for
the Financed Student Loans for other Student Loans held by the Trustee as
trustee under other indentures, if any, securing obligations of the
Corporation or obligations of other subsidiaries of SLFC, or for trusts
established by the Corporation or other subsidiaries of SLFC.  In that event,
the billings submitted to the Department of Education for interest subsidy
payments and Special Allowance Payments on Financed Student Loans would be
consolidated with the billings for such payments for Student Loans held under
such other indentures and trusts using the same lender identification number
and payments on such billings would be made by the Department of Education to
the Trustee in lump sum form.  Such lump sum payments would then be allocated
by the Trustee among the various trusts and indentures using the same lender
identification number.

    In addition, such sharing of the lender identification number may result
in the receipt of Guarantee Payments by Guarantee Agencies in lump sum form.
In that event, such payments would be allocated by the Trustee among the
various trusts and indentures in a manner similar to the allocation process
for interest subsidy payments and Special Allowance Payments.

    The Department of Education regards the Trustee as the party primarily
responsible to the Department of Education for any liabilities owed to the
Department of Education or Guarantee Agencies resulting from the Trustee's
activities in the Federal Family Education Loan Program.  As a result, if the
Department of Education or a Guarantee Agency were to determine that the
Trustee owes a liability to the Department of Education or a Guarantee Agency
on any Student Loans for which the Trustee is or was legal titleholder,
including loans held under the Indenture or such other trusts or indentures,
the Department of Education or the Guarantee Agency might seek to collect that
liability by offset against payments due the Trustee under the Indenture.  If
the Department of Education or a Guarantee Agency determines such a liability
exists in connection with a trust or indenture using the shared lender
identification number, the Department of Education or the Guarantee Agency
would be likely to collect that liability by offsetting against amounts due
the Trustee under the shared lender identification number, including amounts
owed in connection with the Financed Student Loans.  Such offsetting of
payments due to the Trustee with respect to the Financed Student Loans could
adversely affect the receipt of revenues under the Indenture and the
Corporation's ability to pay interest and principal on the Notes.

    In addition, other trusts or indentures using the shared lender
identification number may in a given quarter incur origination fees that
exceed the interest subsidy payments and Special Allowance Payments payable by
the Department of Education on the loans held under such other trusts and
indentures, resulting in the payment from the Department of Education received
by the Trustee under such shared lender identification number for that quarter
equaling an amount that is less than the amount owed by the Department of
Education on the Financed Student Loans for that quarter.

    The Indenture and the indentures or trust agreements under which the
Trustee may separately hold Student Loans which share the lender
identification number to be used by the Trustee (the separate trusts created
thereunder being collectively referred to herein as the "Corporation Trusts")
may require a Corporation Trust (including the Trust Estate under the
Indenture) to indemnify the other Corporation Trusts for a shortfall or an
offset by the Department of Education or a Guarantee Agency arising from the
Student Loans held by the Trustee on such Corporation Trust's behalf.  To the
extent that the Trustee is required to indemnify other Corporation Trusts from
the assets held under the Indenture as part of the Trust Estate with respect
to an offset by the Department of Education or a Guarantee Agency arising from
Financed Student Loans held by the Trustee under the Indenture, such
indemnification obligation could adversely affect the amount of assets in the
Trust Estate and the Corporation's ability to pay principal of and interest on
the Notes.  Also, to the extent that the Trustee may be entitled to
indemnification with respect to an offset by the Department of Education or a
Guarantee Agency arising from

                                      -39-
<PAGE>
 
Student Loans held by the Trustee for a Corporation Trust other than the Trust
Estate under the Indenture, there can be no assurance that the amount of funds
available to the Trustee with respect to such right of indemnification may be
adequate to compensate the Trust Estate under the Indenture and Noteholders
for any previous reduction in the Trust Estate.

DEFEAT OR LACK OF PERFECTED SECURITY INTEREST IN TRUST ESTATE ASSETS

    The Higher Education Act provides that a security interest in student
loans made pursuant to the Federal Family Education Loan Program may be
perfected either through the taking of possession of such loans or by the
filing of notice of such security interest in the manner in which security
interests in accounts may be perfected by applicable state law.  The Uniform
Commercial Code as in effect in the State of South Dakota provides for
perfection of security interests in accounts by the filing of financing
statements with the Secretary of State.  The perfection of the security
interest in the Financed Student Loans granted by the Corporation to the
Trustee is to be accomplished by the filing of financing statements.  SLFC,
acting as custodial agent for the Trustee, will retain possession of the
promissory notes evidencing the Financed Student Loans.  The Corporation is a
wholly-owned subsidiary of SLFC.  If, through fraud, inadvertence or
otherwise, a third-party lender or purchaser acting in good faith were to
obtain possession of any such promissory notes, the security interest of the
Trustee in the related Financed Student Loans could be defeated.  See "Certain
Relationships Among Financing Participants" herein.

    The Trustee's security interest in revenues, moneys, evidences of
indebtedness (including any Financed Student Loans that are not made under the
Federal Family Education Loan Program) and, unless registered in the name of
the Trustee, securities payable into the various Funds and Accounts under the
Indenture does not constitute a perfected security interest until such
revenues, moneys, evidences of indebtedness and securities are received by the
Trustee.

INSOLVENCY OF LENDERS AFFECTING THE TRANSFER OF STUDENT LOANS

    Each Student Loan Purchase Agreement is structured as, and intended to
effectuate, a valid sale and assignment by the Lender to the Original Issuer
or the Trustee on behalf of the Corporation, as applicable, of the Financed
Student Loans transferred thereunder.  Notwithstanding the foregoing, if a
Lender were to become subject to any Insolvency Law and a creditor or
trustee-in-bankruptcy of such Lender were to take the position that the sale
of Financed Student Loans by such Lender should instead be treated as a pledge
of such Financed Student Loans to secure a borrowing, delays in payments on
the Notes from collections on Financed Student Loans could occur or (should
the court rule in favor of such Lender or such creditor) reductions in the
amounts of such payments could result.  In the event of insolvency of any such
Lender that is a bank, moreover, its affairs might become subject to Federal
Deposit Insurance Corporation ("FDIC") receivership.  In such case, the FDIC,
as a receiver, or a court could treat the transfer of the Financed Student
Loans to the Original Issuer or the Trustee on behalf of the Corporation as an
assignment of collateral as security for the benefit of the Original Issuer or
the Corporation as a creditor of such Lender.  If the transfer of the Financed
Student Loans to the Original Issuer or the Trustee on behalf of the
Corporation is deemed to create a security interest therein, a tax or
government lien on property of such Lender arising before the Financed Student
Loans were transferred may have priority over the Trustee's interest in such
Financed Student Loans.  If such Lender becomes subject to receivership, to
the extent that the transfer of the Financed Student Loans is deemed to create
a security interest, and that such interest was validly perfected before such
Lender's insolvency and was not taken in contemplation of insolvency or with
the intent to hinder, delay or defraud such Lender or its creditors, such
security interest should not be subject to avoidance and payments with respect
to the Financed Student Loans should not be subject to recovery by such
Lender's creditors.  The Corporation will receive an opinion of counsel,
subject to the assumptions and limitations set forth therein, that the
provisions of the Indenture, the Student Loan Purchase Agreements, and the
SLFC Servicing Agreement and the actions required thereunder in connection
with the acquisition of Financed Student Loans are sufficient to create both a
perfected security interest in favor of the Trustee against any such Lender in
the Financed Student Loans, if the transfer of Financed Student Loans by such
Lender is considered as an assignment of collateral as security for an
obligation, as well as a perfected security interest in favor of the Trustee
against the Corporation in the

                                      -40-
<PAGE>
 
Financed Student Loans.  No assurance can be given that delays in receipt of
funds with respect to the Financed Student Loans will not occur even if no
such prior liens exist.  Moreover, no assurance can be given that the FDIC
would not seek to effect the release of the Financed Student Loans to it, as
receiver, by accelerating such Lender's "debt" and repaying the outstanding
amount thereof.

FAILURE TO COMPLY WITH CONSUMER PROTECTION LAWS

    Numerous federal and state consumer protection laws and related
regulations impose substantial requirements upon lenders and servicers
involved in consumer finance.  Also, some state laws impose finance charge
ceilings and other restrictions on certain consumer transactions and require
contract disclosures in addition to those required under federal law.  These
state laws are, in large part, preempted by the Higher Education Act.
However, the form of promissory notes required by the Department of Education
for Federal Family Education Loan Program loans provides that holders of such
promissory notes evidencing certain loans made to borrowers attending
for-profit schools are subject to any defenses that the borrower may have
against the school.  Moreover, the Indenture permits, under certain
circumstances, the Financing of Student Loans other than those made under the
Federal Family Education Loan Program.  Such state laws may not be pre-empted
as they apply to any such Student Loans.

HOLDERS OF AUCTION RATE SERIES 1998-1 NOTES AND TAX EXEMPT FIXED RATE SERIES
1998-1 NOTES MAY HAVE TO REINVEST AMOUNTS RECEIVED FROM CALLS FOR REDEMPTION
FROM UNUSED PROCEEDS AT A LOWER RATE OF RETURN

    The Corporation expects approximately $245,100,000 of the Series 1998-1
Note proceeds deposited in the Series 1998-1 Tax Exempt Acquisition Account to
be used to originate or purchase Eligible Loans on or before April 15, 2002.
If such proceeds are not so used, they may be used to redeem Tax Exempt
Auction Rate Series 1998-1 Senior Notes which are called for redemption and,
if no Tax Exempt Auction Rate Series 1998-1 Senior Notes remain Outstanding,
Tax Exempt Fixed Rate Series 1998-1 Notes which are called for redemption.
Investors holding such Tax Exempt Series 1998-1 Notes (particularly Tax Exempt
Fixed Rate Series 1998-1 Notes) which are called for redemption may be unable
to reinvest the proceeds of the redemption at the same yield as the Tax Exempt
Series 1998-1 Notes.  Also, depending on the price at which investors
purchased such Series 1998-1 Notes, their yield may be adversely affected by
such early call for redemption.

    The Corporation expects approximately $65,100,000 of the Series 1998-1
Note proceeds deposited in the Series 1998-1 Taxable Acquisition Account to be
used to originate or purchase Eligible Loans on or before February 1, 1999.
If such proceeds are not so used, they may be transferred to the Retirement
Account and used to redeem Taxable Auction Rate Series 1998-1 Senior Notes
which are called for redemption.  Investors holding such Taxable Auction Rate
Series 1998-1 Senior Notes which are called for redemption may be unable to
reinvest the proceeds of the redemption at the same yield as the Taxable
Auction Rate Series 1998-1 Senior Notes.  Also, depending on the price at
which investors purchased such Series 1998-1 Notes, their yield may be
adversely affected by such early call for redemption.  See "Application of
Series 1998-1 Note Proceeds" and "Description of Series 1998-1 Notes --
Special Call for Redemption -- From Unused Proceeds."

REDUCTION IN AMOUNTS AVAILABLE TO PAY NOTES DUE TO THE VARIABILITY OF ACTUAL
CASH FLOWS AND DUE TO THE INABILITY OF GUARANTEE AGENCIES TO MAKE GUARANTEE
PAYMENTS

    Amounts received with respect to the Financed Student Loans for a
particular period may vary in both timing and amount from the payments
actually due on the Financed Student Loans for a variety of economic, social
and other factors, including both individual factors, such as additional
periods of deferment or forbearance prior to or after a borrower's
commencement of repayment, and general factors, such as a general economic
downturn which could increase the amount of defaulted Financed Student Loans.
Failures by borrowers to pay timely the principal and interest on the Financed
Student Loans will affect the amount of revenues, which may reduce the amount
available to be paid to the Series 1998-1 Noteholders.  The inability of any
Guarantee Agency to meet its guarantee obligations could reduce the amount
available to be paid to the Series 1998-1 Noteholders.

                                      -41-

HOLDERS OF SERIES 1998-1 NOTES WHICH ARE PREPAID OR CALLED FOR REDEMPTION DUE
TO ACCELERATED PAYMENTS WITH RESPECT TO FINANCED STUDENT LOANS MAY HAVE TO
REINVEST AMOUNTS RECEIVED FROM PREPAYMENTS OR CALLS FOR REDEMPTION AT A LOWER
RATE OF RETURN

    Principal payments with respect to the Financed Student Loans may be
influenced by a variety of economic, geographic, social and other factors. The
Financed Student Loans may be prepaid at any time without penalty.  The
Corporation believes that in a fluctuating interest rate environment a factor
affecting the prepayment rate on a large pool of loans such as the Student
Loan Portfolio is the difference between the interest rates on the loans and
prevailing interest rates generally (giving consideration to the cost of any
refinancing).  In general, if interest rates fall below the interest rates on
the Financed Student Loans, the rate of prepayment would be expected to
increase.  Conversely, if interest rates rise above the interest rates on the
Financed Student Loans, the rate of prepayment would be expected to decrease.
Historically, the Original Issuer has not tracked instances of partial or full
prepayment of its Student Loan Portfolio except to the extent such prepayments
occurred in connection with defaults.  No assurances can be given as to the
actual rate of prepayment with respect to the Financed Student Loans in the
Student Loan Portfolio.  Other factors affecting prepayment of loans include
changes in the borrower's employment and other economic circumstances, and
refinancing opportunities which may provide more favorable repayment terms
such as those offered under various consolidation loan programs, including the
federal direct consolidation loan programs.  Because of the benefits of
consolidating numerous Student Loans into a single loan and, in some cases,
obtaining more favorable repayment terms, a borrower may choose to prepay
Financed Student Loans through consolidation programs regardless of the
general level of interest rates.  In addition, the rate of the payments of
principal on the Notes will be directly related to the actual amortization
schedules of the Financed Eligible Loans.  See "Description of Federal Family
Education Loan Program -- Loan Terms -- Repayment."

    Receipt of principal and interest on Financed Student Loans may be
accelerated due to: (1) default claims or claims due to the disability, death
or bankruptcy of the borrowers or school closure; (2) actual principal
amortization periods which are shorter than those assumed based upon the
current analysis of the expected Student Loan Portfolio; (3) the commencement
of principal repayment by borrowers on earlier dates than are assumed based
upon the current analysis of the expected Student Loan Portfolio; and (4)
economic conditions being such that borrowers elect to refinance or prepay
their loans prior to maturity.  Eligible lenders, including the Trustee on
behalf of the Corporation, and the Secretary of Education may make
Consolidation Loans to borrowers for the purpose of retiring borrowers'
existing loans under various federal higher education loan programs.  To the
extent that Financed Student Loans are repaid with Consolidation Loans, the
Corporation will realize payment of such loans earlier than projected.  In
addition, under certain circumstances, a Lender will be obligated to
repurchase Financed Student Loans from the Trust Estate pursuant to its
Student Loan Purchase Agreement as a result of breaches of its
representations, warranties or covenants.

    Taxable LIBOR Rate Series 1998-1 Notes are subject to prepayment in
amounts related to the amount of principal payments received with respect to
Student Loan Financed with the proceeds of the Taxable Series 1998-1 Notes in
the Acquisition Fund.  Because of the uncertainties relating to the timing of
receipt of principal of Student Loans expected to be Financed with proceeds of
the Taxable Series 1998-1 Notes, the actual level of prepayments resulting
therefrom cannot be definitively stated.  Investors holding Taxable LIBOR Rate
Series 1998-1 Notes which are prepaid may be unable to reinvest the proceeds
of the prepayment at the same yield as the Taxable LIBOR Rate Series 1998-1
Notes.  Also, depending on the price at which investors purchased such Series
1998-1 Notes, their yield may be adversely affected by such prepayment.

    The Series 1998-1 Notes (other than the Taxable LIBOR Rate Series 1998-1
Notes) are subject to call for redemption from revenues under the Indenture in
excess of required debt service payments and other expenses under the
Indenture and all Series 1998-1 Notes are subject to call for redemption if
the Student Loan Portfolio balance is less than 10% of the amount deposited to
the Acquisition Fund on the Date of Issuance.  Investors holding Series 1998-1
Notes which are called for redemption may be unable to reinvest the proceeds
of the redemption at the same yield as the Series 1998-1 Notes they previously
held.  Also, depending on the price at which investors purchased such Series
1998-1 Notes, their yield may be adversely affected by such call for
redemption.

DIFFERENCES IN PRINCIPAL PAYMENTS AMONG SERIES OF TAXABLE SERIES 1998-1 NOTES
WITH RESPECT TO RECEIPT OF PAYMENTS ON THE FINANCED STUDENT LOANS

    The Taxable Auction Rate Series 1998-1 Senior Notes are not expected to
receive any payments of principal from principal payments on Financed Student
Loans until all Taxable LIBOR Rate Series 1998-1 Notes have been paid in full.
Series 1998-1J Notes will receive no payments of principal from such source
until the Series 1998-1I Notes have been paid in full. Therefore, the Series
1998-1I Notes and (as compared to all Taxable Series 1998-1 Notes other than
Series 1998-1I Notes) the Series 1998-1J Notes bear relatively greater risk
than other series of Taxable Series 1998-1 Notes of an increased rate of
principal payments derived from principal payments relating to Financed
Student Loans.

THE AVERAGE LIFE OF THE SERIES 1998-1 NOTES MAY BE LENGTHENED AS A RESULT OF
EXTENSION OF PAYMENTS ON THE FINANCED STUDENT LOANS

    Principal and interest payments on Financed Student Loans may be delayed
due to:  (1) borrowers entering Deferment Periods due to a return to school or
other eligible purposes: (2) forbearance being granted to borrowers; (3) loans
becoming delinquent for periods longer than assumed; (4) actual loan principal
amortization periods which are longer than those expected based upon the
current analysis of the expected Student Loan Portfolio; and (5) the
commencement of principal repayment by borrowers at dates later than those
assumed based upon the current analysis of the Eligible Loans expected to be
Financed.  These factors may lengthen the remaining term of the Financed
Student Loans and the average life of the Series 1998-1 Notes.  See
"Description of Federal Family Education Loan Program -- Loan Terms --
Repayment."

THE TRUSTEE'S INABILITY TO LIQUIDATE FINANCED STUDENT LOANS AND POSSIBLE
INSUFFICIENCY OF TRUST ESTATE ASSETS

    If an Event of Default occurs under the Indenture, subject to certain
conditions, the Trustee is authorized, without the consent of the Noteholders,
to sell the Financed Student Loans.  There can be no assurance that the
Trustee would be able to find a purchaser for the Financed Student Loans in a
timely manner or that the market value of such Financed Student Loans would,
at any time, be sufficient to provide for the payment of all amounts due with
respect to the Notes.  The Higher Education Act requires that the purchaser of
the Student Loans must be an eligible lender under the Higher Education Act.

    Additionally, any such sale by the Trustee would need to comply with the
applicable requirements of the Uniform Commercial Code then in effect in the
State of South Dakota, which currently provides that such sale may be by
private or public proceedings conducted at any time or place and on any terms,
provided that every aspect of the sale, including the method, manner, time,
place and terms, be commercially reasonable.  If it were established that the
Trustee failed to proceed in a commercially reasonable manner, the Corporation
may be entitled to recover from the Trustee (which would, in turn, look to the
Trust Estate for indemnification) any loss to the Corporation caused by such
failure.  However, if the Trustee sells the Student Loans in the usual manner
in any recognized market therefor, or sells at the price current in such
market at the time of such sale, or has otherwise sold the Student Loans in
conformity with reasonable commercial practices among dealers in Student
Loans, the Trustee will have sold the Student Loans in a commercially
reasonable manner.  Further, a sale which has been approved in any judicial
proceeding or by any bona fide creditors' committee or representatives of
creditors of the Corporation shall conclusively be deemed to be commercially
reasonable.  Seeking such approval could result in delays in the ultimate
disposition of the Financed Student Loans.

THE FINANCIAL STATUS OF GUARANTEE AGENCIES WILL AFFECT THEIR ABILITY TO MAKE
GUARANTEE PAYMENTS

    The Higher Education Act requires all loans made under the Federal Family
Education Loan Program to be unsecured.  As a result, the only security for
payment of the Financed Eligible Loans is the Guarantee Agreements between the
Trustee and each Guarantee Agency.  A deterioration in the financial status of
the Guarantee Agencies and their ability to honor guarantee claims with
respect to the Financed Eligible Loans could

                                      -43-
<PAGE>
 
result in a delay in making or a failure to make Guarantee Payments to the
Trustee.  Failures by borrowers of Student Loans generally to pay timely the
principal and interest due on such Student Loans could obligate the Guarantee
Agencies to make payments thereon, which could adversely affect the solvency
of the Guarantee Agencies and their ability to meet their guarantee
obligations (including with respect to the Financed Student Loans).  Moreover,
to the extent that the Department of Education pays reimbursement claims
submitted by a Guarantee Agency for any fiscal year exceeding certain
specified levels (see "Description of the Guarantee Agencies -- Effect of
Annual Claims Rate"), the Department of Education's obligation to reimburse
the Guarantee Agency for losses will be reduced on a sliding scale from a
maximum of 100% (98% for loans made on or after October 1, 1993) to a minimum
of 80% (78% for loans made on or after October 1, 1993) of Guarantee Agency
payments, except that death, disability, bankruptcy, closed school and false
certification claims are reimbursed 100% by the Department of Education.

    Pursuant to Section 432(o) of the Higher Education Act, if the Department
of Education has determined that a Guarantee Agency is unable to meet its
insurance obligations, the holders of loans guaranteed by such Guarantee
Agency may submit claims directly to the Department of Education and the
Department of Education is required to pay the full Guarantee Payment due with
respect thereto in accordance with standards no more stringent than those
applied by the Guarantee Agency.  However, the Department of Education's
obligation to pay guarantee claims directly in this fashion is contingent upon
the Department of Education making the determination referred to above.  There
can be no assurance that the Department of Education would ever make such a
determination with respect to a Guarantee Agency or, if such a determination
were made, that such determination or the ultimate payment of such guarantee
claims would be made in a timely manner.  See "Description of the Federal
Family Education Loan Program."

USE OF SERIES 1998-1 NOTE PROCEEDS AND REVENUES TO ACQUIRE INVESTMENT
AGREEMENTS

    The proceeds of the Series 1998-1 Notes that are not used to acquire
Financed Student Loans on the Date of Issuance will be used to acquire a
limited number of investment agreements with one or more Investment Providers.
Revenues deposited in the Revenue Fund, the Note Fund and the Surplus Fund
also are expected to be used to acquire a limited number of investment
agreements with one or more Investment Providers.  Each such investment
agreement will initially involve a significant portion of the proceeds of the
Series 1998-1 Notes.  If any Investment Provider were unable to repay funds
loaned to it under an unsecured investment agreement, or if the collateral
pledged for a secured investment agreement were insufficient or unavailable
for any reason, the Corporation's ability to pay the principal of and interest
on the Series 1998-1 Notes could be adversely affected.

CHANGE OF RATINGS OF THE SERIES 1998-1 NOTES

    It is a condition to issuance of the Series 1998-1 Notes that they be
rated as indicated under the caption "Ratings." Ratings are based primarily on
the credit underlying the Financed Eligible Loans, the existence and amount of
subordinate debt, any credit enhancement and the legal structure of the
transaction.  The ratings are not a recommendation to purchase, hold or sell
Series 1998-1 Notes and do not take into account factors such as the market
price or suitability for a particular investor.  There is no expectation that
any additional rating agency will rate the Series 1998-1 Notes, and there can
be no assurance the rating that would be assigned by any such other rating
agency would be equivalent to the initial ratings described herein.  Moreover,
there can be no assurance that the ratings will remain for any given period of
time or that ratings will not be lowered or withdrawn by any Rating Agency if
in such Rating Agency's judgment circumstances so warrant. Any such lowering
or withdrawal could adversely affect the market value of the Series 1998-1
Notes.

LIMITED LIQUIDITY OF THE SERIES 1998-1 NOTES

    The Series 1998-1 Notes will not be listed on any national security
exchange.  There is currently no secondary market for the Series 1998-1 Notes
and there is no assurance that one will develop or, if such a market does
develop, that such market will continue. The Underwriters expect, but will not
be obligated, to make a market

                                      -44-
<PAGE>
 
in the Series 1998-1 Notes.  As a result, investors must be prepared to bear
the risk of holding the Series 1998-1 Notes for so long as the Series 1998-1
Notes remain outstanding.

SWAP AGREEMENTS

    Under the Indenture, the Corporation may execute Swap Agreements if
certain requirements are met, including that the Trustee shall have received
written confirmation from each Rating Agency that the execution and delivery
of the Swap Agreement will not cause the reduction or withdrawal of any rating
or ratings then applicable to any Outstanding Notes.  No Swap Agreement is
being entered into in connection with the issuance of the Series 1998-1 Notes.
See "Source of Payment and Security for the Notes -- Additional Indenture
Obligations."  Swap Agreements carry risks relating to the credit quality of
the counterparty and the legal enforceability of the Swap Agreement.

EFFECT OF BOOK-ENTRY REGISTRATION

    Initially, the Series 1998-1 Notes will be in the form of certificates
registered in the name of Cede & Co., the nominee for DTC, and will not be
registered in the names of the beneficial owners of the Series 1998-1 Notes or
their nominees.  Because of this, unless and until definitive securities are
issued, beneficial owners of the Series 1998-1 Notes will not be recognized by
the Trustee as "Holders" (as such term is used in the Indenture).  Therefore,
unless and until certificated securities are issued, beneficial owners of the
Series 1998-1 Notes will only be able to exercise the rights of Holders
indirectly through DTC and its participating organizations in the United
States or Cedel Bank, societe anonyme or the Euroclear System in Europe.  See
"Description of Series 1998-1 Notes -- Book-Entry-Only System."


                      DESCRIPTION OF SERIES 1998-1 NOTES

    The Series 1998-1 Notes will be issued pursuant to the Indenture. The form
of the Indenture has been filed as an exhibit to the Registration Statement of
which this Prospectus is a part.

DTC, Cedel and Euroclear and has not been independently verified by the

information is not, and should not be construed as, a representation by the
Original Issuer, the Corporation or the Underwriters as to its accuracy or
completeness or otherwise.

    DTC will act as securities depository for the Series 1998-1 Notes.  Upon
the issuance of the Series 1998-1 Notes, one or more fully registered notes
for each series, in the aggregate principal amount of the Series 1998-1 Notes,
are to be registered in the name of Cede & Co., as nominee for DTC.  So long
as Cede & Co. is the Holder of the Series 1998-1 Notes, as nominee of DTC,
references herein to the owners or Holders of the Series 1998-1 Notes shall
mean DTC or its nominee, Cede & Co., and shall not mean the Beneficial Owners
of the Series 1998-1 Notes.  Noteholders may hold their certificates through
DTC (in the United States) or Cedel or Euroclear (in Europe) if they are
participants of such systems, or indirectly through organizations that are
participants in such systems.

    Cede, as nominee for DTC, will hold the global Notes.  Cedel and Euroclear
will hold omnibus positions on behalf of the Cedel Participants and the
Euroclear Participants, respectively, through customers' securities accounts
in Cedel's and Euroclear's names on the books of their respective depositories
(collectively, the "Depositories") which in turn will hold such positions in
customers' securities accounts in the Depositories' names on the books of DTC.

    DTC is a limited-purpose trust company organized under New York Banking
Law, a "banking organization" within themeaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act.  DTC
holds securities that its participants (the "DTC Participants") deposit with
DTC.  DTC also facilitates the settlement among DTC Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in DTC Participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
DTC Participants include securities brokers and dealers, banks, trust
companies, clearing corporations, and certain other organizations.  DTC is
owned by a number of DTC Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc., and the National Association of
Securities Dealers, Inc.  Access to the DTC system is also available to others
such as securities brokers and dealers, banks and trust companies that clear
through or maintain a custodial relationship with a DTC Participant, either
directly or indirectly (the "Indirect Participants").  The Rules applicable to
DTC and the DTC Participants are on file with the Commission.

    Transfers between DTC Participants will occur in accordance with DTC
rules.  Transfers between Cedel Participants and Euroclear Participants will
occur in the ordinary way in accordance with their applicable rules and
operating procedures.

    Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedel
Participants or Euroclear Participants, on the other, will be effected in DTC
in accordance with DTC rules on behalf of the relevant European international
clearing system by its Depository; however, such cross-market transactions
will require delivery of instructions to the relevant European international
clearing system by the counterparty in such system in accordance with its
rules and procedures and within its established deadlines (European time).
The relevant European international clearing system will, if the transaction
meets its settlement requirements, deliver instructions to its Depository to
take action to effect final settlement on its behalf by delivering or
receiving securities in DTC, and making or receiving payment in accordance
with normal procedures for same-day funds settlement applicable to DTC.  Cedel
Participants and Euroclear Participants may not deliver instructions directly
to the Depositories.

    Because of time-zone differences, credits of securities in Cedel or
Euroclear as a result of a transaction with a DTC Participant will be made
during the subsequent securities settlement processing, dated the business day
following the DTC settlement date, and such credits or any transactions in
such securities settled during such processing will be reported to the
relevant Cedel Participant or Euroclear Participant on such business day.
Cash received in Cedel or Euroclear as a result of sales of securities by or
through a Cedel Participant or a Euroclear Participant to a DTC Participant
will be received with value on the DTC settlement date but will be available
in the relevant Cedel or Euroclear cash account only as of the business day
following settlement in DTC.

                                      -46-

    Day traders that use Cedel or Euroclear and that purchase the globally
offered Series 1998-1 Notes from DTC Participants for delivery to Cedel
Participants or Euroclear Participants should note that these trades may fail
on the sale side unless affirmative actions are taken.  Participants should
consult with their clearing system to confirm that adequate steps have been
taken to assure settlement.

    Purchases of the Series 1998-1 Notes (in authorized denominations) under
the book-entry system may be made only through brokers and dealers who are, or
act through, DTC Participants.  The DTC Participants purchasing the Series
1998-1 Notes will receive a credit balance in the records of DTC.  The
ownership interest of the actual purchaser of each Series 1998-1 Note (a
"Beneficial Owner") will be recorded in the records of the applicable DTC
Participant or Indirect Participant. Beneficial Owners will not receive
written confirmation from DTC of their purchase, but Beneficial Owners are
expected to receive from the applicable DTC Participant or Indirect
Participant written confirmations providing details of the transaction, as
well as periodic statements of their holdings.  Transfers of beneficial
ownership of the Series 1998-1 Notes will be accomplished by book entries made
by the DTC Participants or Indirect Participants who act on behalf of the
Beneficial Owners and, if necessary, in turn by DTC.  No Series 1998-1 Notes
will be registered in the names of the Beneficial Owners, and Beneficial
Owners will not receive certificates representing their ownership interest in
the Series 1998-1 Notes, except in the event participation in the book-entry
system is discontinued as described below.

    The Corporation and the Trustee will recognize DTC or its nominee as the
Holder of the Series 1998-1 Notes for all purposes, including notice purposes.
DTC has no knowledge of the actual Beneficial Owners of the Series 1998-1
Notes; DTC's records reflect only the identity of the DTC Participants to
whose accounts such Series 1998-1 Notes are credited, which may or may not be
the Beneficial Owners. The DTC Participants and Indirect Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.

    Conveyance of notices and other communications by DTC to DTC Participants,
by DTC Participants to Indirect Participants and by DTC Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among DTC, DTC Participants, Indirect Participants and Beneficial Owners,
subject to any statutory and regulatory requirements as may be in effect from
time to time.  Beneficial Owners may desire to make arrangements with a DTC
Participant or an Indirect Participant so that all notices of calls of Series
1998-1 Notes for redemption or other communications to DTC which affect such
Beneficial Owners, and notification of all interest payments, will be
forwarded in writing by the DTC Participant or Indirect Participant.  Any
failure of DTC to advise any DTC Participant, or of any DTC Participant or
Indirect Participant to advise a Beneficial Owner, of any notice of call for
redemption or its content or effect will not affect the validity of the
redemption of the Series 1998-1 Notes called for redemption or any other
action premised on such notice.

    Neither DTC nor Cede & Co. will consent or vote with respect to the Series
1998-1 Notes.  Under its usual procedures, DTC mails an Omnibus Proxy to the
Corporation as soon as possible after the record date it establishes.  The
Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those DTC
Participants to whose accounts the Series 1998-1 Notes are credited on the
record date (identified in a listing attached to the Omnibus Proxy).

    Payments of principal of, premium, if any, and interest on the Series
1998-1 Notes will be made to DTC or its nominee, Cede & Co., as Holder of the
Series 1998-1 Notes.  DTC's current practice is to credit the accounts of the
DTC Participants on payment dates in accordance with their respective holdings
shown on the records of DTC, unless DTC has reason to believe that it will not
receive payment on that date.  Payments by DTC Participants and Indirect
Participants to Beneficial Owners will be governed by standing instructions
and customary practices, as is the case with securities held for the accounts
of customers in bearer form or registered in "street name", and will be the
responsibility of such DTC Participant or Indirect Participant and not of DTC
or the Corporation, subject to any statutory and regulatory requirements as
may be in effect from time to time. Payment of principal and interest to DTC
is the responsibility of the Corporation and the Trustee, disbursement of such
payments to DTC Participants shall be the responsibility of DTC, and
disbursement of such payments to the Beneficial Owners shall be the
responsibility of DTC Participants and Indirect Participants.

    By purchasing the Auction Rate Series 1998-1 Senior Notes, whether in an
Auction or otherwise, each prospective purchaser of the Auction Rate Series
1998-1 Senior Notes or its Broker-Dealer must agree and will be deemed to have
agreed: (i) to have its beneficial ownership of the Auction Rate Series 1998-1
Senior Notes maintained at all times in Book-Entry Form for the account of its
DTC Participant, which in turn will maintain records of such beneficial
ownership, and to authorize such DTC Participant to disclose to the Auction
Agent such information with respect to such beneficial ownership as the
Auction Agent may request; and (ii) so long as the beneficial ownership of the
Auction Rate Series 1998-1 Senior Notes is maintained in Book-Entry Form, to
sell, transfer or otherwise dispose of the Auction Rate Series 1998-1 Senior
Notes only pursuant to a Bid or a Sell Order in an Auction, or otherwise
through a Broker-Dealer, provided that in the case of all transfers other than
those pursuant to an Auction, the Existing Holder of the Auction Rate Series
1998-1 Senior Notes so transferred, its DTC Participant or Broker-Dealer
advises the Auction Agent of such transfer.

    For every transfer of the Series 1998-1 Notes, the Beneficial Owner may be
charged a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto.

    So long as Cede & Co. or its registered assign is the registered holder of
the Series 1998-1 Notes, the Corporation and the Trustee will be entitled to
treat Cede & Co., or its registered assign, as the absolute owner thereof for
all purposes of the Indenture and any applicable laws, notwithstanding any
notice to the contrary received by the Corporation or the Trustee, and the
Corporation and the Trustee will have no responsibility for transmitting
payments to, communicating with, notifying, or otherwise dealing with any
Beneficial Owners of the Series 1998-1 Notes.

    If (i) the Series 1998-1 Notes of any series are not eligible for the
services of DTC, (ii) DTC determines to discontinue providing its services
with respect to the Series 1998-1 Notes of any series or (iii) the Corporation
determines that a system of book-entry transfers for Series 1998-1 Notes of
any series, or the continuation thereof, through DTC is not in the best
interest of the Beneficial Owners or the Corporation, the Corporation may
either identify another qualified securities depository or direct or cause
Series 1998-1 Note certificates for such series to be delivered to Beneficial
Owners thereof or their nominees and, if certificates are delivered to the
Beneficial Owners, the Beneficial Owners or their nominees, upon
authentication of the Series 1998-1 Notes of such series in authorized
denominations and registration thereof in the Beneficial Owners' or nominees'
names, shall become the Holders of such Series 1998-1 Notes for all purposes.
In any such event, the Trustee is to mail an appropriate notice to the
securities depository for notification to DTC Participants and Beneficial
Owners of the substitute securities depository or the issuance of Series
1998-1 Note certificates to Beneficial Owners or their nominees, as
applicable.

    Cedel Bank, societe anonyme ("Cedel") is incorporated under the laws of
Luxembourg as a professional depository. Cedel holds securities for its
participating organizations ("Cedel Participants") and facilitates the
clearance and settlement of securities transactions between Cedel Participants
through electronic book-entry changes in accounts of Cedel Participants,
thereby eliminating the need for physical movement of certificates.
Transactions may be settled in Cedel in any of 32 currencies, including United
States dollars.  Cedel provides to its Cedel Participants, among other things,
services for safekeeping, administration, clearance and settlement of
internationally traded securities and securities lending and borrowing.  Cedel
interfaces with domestic markets in several countries.  As a professional
depository, Cedel is subject to regulation by the Luxembourg Monetary
Institute.  Cedel Participants are recognized financial institutions around
the world, including underwriters, securities brokers and dealers, banks,
trust companies, clearing corporations and certain other organizations and may
include the underwriters of the Series 1998-1 Notes.  Indirect access to Cedel
is also available to others, such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a Cedel
Participant, either directly or indirectly.

    The Euroclear System was created in 1968 to hold securities for
participants of the Euroclear System ("Euroclear Participants") and to clear
and settle transactions between Euroclear Participants through simultaneous
electronic book-entry delivery against payment, thereby eliminating the need
for physical movement of certificates

                                      -48-
<PAGE>
 
and any risk from lack of simultaneous transfers of securities and cash.
Transactions may now be settled in any of 32 currencies, including United
States dollars.  The Euroclear System includes various other services,
including securities lending and borrowing and interfaces with domestic
markets in 25 countries generally similar to the arrangements for cross-market
transfers with DTC described above.  The Euroclear System is operated by
Morgan Guaranty Trust Company of New York, Brussels, Belgium office (the
"Euroclear Operator" or "Euroclear"), under contract with Euroclear Clearance
System, Societe Cooperative, a Belgian cooperative corporation (the
"Cooperative").  All operations are conducted by the Euroclear Operator, and
all Euroclear securities clearance accounts and Euroclear cash accounts are
accounts with the Euroclear Operator, not the Cooperative.  The Cooperative
Board establishes policy for the Euroclear System. Euroclear Participants
include banks (including central banks), securities brokers and dealers and
other professional financial intermediaries and may include the underwriters
of any Series of Notes.  Indirect access to the Euroclear System is also
available to other firms that maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.

    The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System.  As such, it
is regulated and examined by the Board of Governors of the Federal Reserve
System and the New York State Banking Department, as well as the Belgian
Banking Commission.

    Securities clearance accounts and cash accounts with the Euroclear
Operator are governed by the Terms and Conditions Governing Use of Euroclear
and the related Operating Procedures of the Euroclear System (collectively,
the "Terms and Conditions").  The Terms and Conditions govern transfers of
securities and cash within the Euroclear System, withdrawal of securities and
cash from the Euroclear System, and receipts of payments with respect to
securities in the Euroclear System. All securities in the Euroclear System are
held on a fungible basis without attribution of specific certificates to
specific securities clearance accounts.  The Euroclear Operator acts under the
Terms and Conditions only on behalf of Euroclear Participants and has no
record of or relationship with persons holding through Euroclear Participants.

    The Euroclear Operator has advised as follows:  Under Belgian law,
investors that are credited with securities on the records of the Euroclear
Operator have a co-property right in the fungible pool of interests in
securities on deposit with the Euroclear Operator in an amount equal to the
amount of interests in securities credited to their accounts.  In the event of
the insolvency of the Euroclear Operator, Euroclear Participants would have a
right under Belgian law to the return of the amount and type of interests in
securities credited to their accounts with the Euroclear Operator.  If the
Euroclear Operator did not have a sufficient amount of interests in securities
on deposit of a particular type to cover the claims of all Participants
credited with such interests in securities on the Euroclear Operator's
records, all Participants having an amount of interests in securities of such
type credited to their accounts with the Euroclear Operator would have the
right under Belgian law to the return of their pro-rata share of the amount of
interests in securities actually on deposit.  Under Belgian law, the Euroclear
Operator is required to pass on the benefits of ownership in any interests in
securities on deposit with it (such as dividends, voting rights and other
entitlements) to any person credited with such interests in securities on its
records.

    Distributions with respect to Series 1998-1 Notes held through Cedel or
Euroclear will be credited to the cash accounts of Cedel Participants or
Euroclear Participants in accordance with the relevant system's rules and
procedures, to the extent received by its Depository.  Such distributions will
be subject to tax reporting in accordance with relevant United States tax laws
and regulations.  See "Tax Matters -- Federal Tax Consequences" and "--
Certain U.S. Federal Income Tax Documentation Requirements."  Cedel or the
Euroclear Operator, as the case may be, will take any other action permitted
to be taken by a Series 1998-1 Noteholder under the Indenture on behalf of a
Cedel Participant or Euroclear Participant only in accordance with its
relevant rules and procedures and subject to its Depository's ability to
effect such actions on its behalf through DTC.

    Although DTC, Cedel and Euroclear have agreed to the foregoing procedures
in order to facilitate transfers of Series 1998-1 Notes among participants of
DTC, Cedel and Euroclear, they are under no obligation to perform or continue
to perform such procedures and such procedures may be discontinued at any
time.

1998-1 Notes in the aggregate Principal Amount of $1,000,000 or more (or, if
less than $1,000,000 in Principal Amount of Series 1998-1 Notes is

in which the Principal Office of the Paying Agent is located on the last
Business Day preceding the applicable Regular Record Date, by electronic

last Business Day preceding such Interest Payment Date, and (ii) with respect
to any regularly scheduled Interest Payment Date for the Tax Exempt Fixed Rate

at the close of business on the Regular Record Date and shall be payable to
the person who is the Holder thereof at the close of business on a special
record date established by the Trustee (a "Special Record Date") for the
payment of any such Defaulted Interest.  Such Special Record Date shall be

Defaulted Interest, and notice of the Special Record Date shall be given to
the Holders of the Series 1998-1 Notes not less than 10 days prior thereto by
first-class mail to each such Holder as shown on the Note Register on a date
selected by the Trustee, stating the date of the Special Record Date and the
date fixed for the payment of such Defaulted Interest. All payments of
principal of and interest on the Series 1998-1 Notes shall be made in lawful
money of the United States of America.

PREPAYMENT OF TAXABLE LIBOR RATE SERIES 1998-1 NOTES

    Principal of the Taxable LIBOR Rate Series 1998-1 Notes shall be prepaid
on any Interest Payment Date from moneys credited to the Retirement Account as
hereinafter described.  The Corporation is required to direct the Trustee to
transfer to the Retirement Account from the Special Redemption and Prepayment
Account any moneys therein, up to an amount equal to the Special Prepayment
Amount, which the Corporation has not determined are reasonably expected to be
required to be transferred to the Note Fund, the Rebate Fund or the Reserve
Fund prior to the next succeeding regularly scheduled Interest Payment Date,
provided no deficiencies exist at the time of such transfer in the Note Fund,
the Rebate Fund or the Reserve Fund.  See "Source of Payment and Security for
the Notes -- Description of Flow of Revenues in the Funds."  Such prepayments
of principal of Taxable LIBOR Rate Series 1998-1 Notes shall, subject to the
Senior Asset Requirement, be allocated between the Taxable LIBOR Rate Series
1998-1 Senior Notes and the Taxable LIBOR Rate Series 1998-1 Subordinate Notes
pro rata.  All such prepayments of principal allocated to the Taxable LIBOR
Rate Series 1998-1 Senior Notes shall be applied to the Series 1998-1I Notes
so long as any such Notes remain Outstanding, and thereafter to the Series
1998-1J Notes.

                                      -50-
<PAGE>
 
Within a given series of Taxable LIBOR Rate Series 1998-1 Notes, the Principal
Amount of such series to be prepaid shall be allocated pro rata to the
reduction of the Principal Amount of all Notes of such series.

    The "Special Prepayment Amount" is an amount, as of the last day of any
month, equal to the excess, if any, of (1) the sum of (a) all payments
received as of such last day with respect to principal of Financed Student
Loans credited to the Series 1998-1 Taxable Acquisition Account, plus (b) the
amount of any Balances theretofore transferred from the Series 1998-1 Taxable
Acquisition Account to the Retirement Account to redeem Taxable Auction Rate
Series 1998-1 Senior Notes which are called for redemption as described below
under "Special Call for Redemption -- From Unused Proceeds," less (c) the
aggregate amount of interest on Financed Student Loans credited to the Series
1998-1 Taxable Acquisition Account which has been capitalized after the
Financing thereof, less (d) the principal component of the repurchase price of
Student Loans originally Financed from Balances in Series 1998-1 Taxable
Acquisition Account which have been repurchased from a Guarantee Agency upon
rehabilitation of such Eligible Loans pursuant to the Higher Education Act,
over (2) the sum of (a) the aggregate of the amounts previously applied to the
reduction of the Principal Amount of all Taxable LIBOR Rate Series 1998-1
Notes, plus (b) the aggregate Principal Amount of Taxable LIBOR Rate Series
1998-1 Notes to be prepaid on the next regularly scheduled Interest Payment
Date from Balances then on hand in the Retirement Account.  Payments described
in clause (1)(a) of the preceding sentence include, without limitation, any
prepayments by borrowers from the proceeds of a Consolidation Loan made or
acquired by the Trustee on behalf of the Corporation or from any other
sources, but exclude, for this purpose, proceeds of the sale or other
disposition of Financed Student Loans to any Person other than a Guarantee
Agency, with respect to Guarantee Payments, or a Lender, with respect to the
repurchase of Financed Student Loans by such Lender pursuant to its repurchase
obligation under a Student Loan Purchase Agreement.

    In general, this prepayment provision is intended to require the
Corporation to prepay Taxable LIBOR Rate Series 1998-1 Notes in amounts
related to the amount of principal payments received with respect to Student
Loans Financed with proceeds of the Taxable Series 1998-1 Notes in the
Acquisition Fund.  See "Weighted Average Life of the Taxable LIBOR Rate Series
1998-1 Notes."  Because of the uncertainties relating to the timing of receipt
of principal of Student Loans expected to be Financed with proceeds of the
Taxable Series 1998-1 Notes, the actual level of prepayments resulting
therefrom cannot be definitively stated.  See "Risk Factors -- Holders of
Series 1998-1 Notes Which are Prepaid or Called for Redemption Due to
Accelerated Payments with respect to Financed Student Loans May Have to
Reinvest Amounts Received From Prepayments or Calls for Redemption at a Lower
Rate of Return."

SPECIAL CALL FOR REDEMPTION

  From Moneys in the Surplus Account

    Tax Exempt Auction Rate Series 1998-1 Senior Notes of any series, Tax
Exempt Fixed Rate Series 1998-1 Senior Notes and Tax Exempt Fixed Rate Series
1998-1 Subordinate Notes, may, at the Corporation's option but subject to

    Taxable Auction Rate Series 1998-1 Senior Notes of any series may, at the
Corporation's option but subject to compliance with the conditions described
under "Senior Asset Requirement" below, be called for redemption, in whole or
in part, and if in part as described under "Selection of Series 1998-1 Notes
for Call for Redemption" below, at a Redemption Price equal to 100% of
Principal Amount of such Notes to be redeemed, plus accrued interest thereon
to the Redemption Date, on any regularly scheduled Interest Payment Date for
such series occurring on or after March 1, 1999, from amounts transferred to
the Series 1998-1 Taxable Retirement Sub-Account from the Series 1998-1
Taxable Surplus Sub-Account and the Series 1998-1 Taxable Reserve Account.  In
general, such transfers are intended to allow the Corporation to call Taxable
Auction Rate Series 1998-1 Senior Notes for redemption to the extent that
revenues under the Indenture allocable to Taxable Series 1998-1 Notes exceed
scheduled debt service payments on the Taxable Series 1998-1 Notes,
prepayments of Taxable LIBOR Rate Series 1998-1 Notes, payments on other
Indenture Obligations and other expenses payable under the Indenture.  Such
revenues could result in whole or in part from Student Loans acquired with,
and from investment earnings on, the proceeds of Additional Notes.  (Any
Additional Notes will not be offered or sold pursuant to this Prospectus.)
See "Summary of the Indenture -- Funds and Accounts -- Surplus Fund" and "--
Reserve Fund."

    Because of the uncertainties relating to the amounts and timing of receipt
of revenues under the Indenture, and the amounts and terms of additional
Indenture Obligations, if any, the amounts expected to be available in the
Surplus Account for such call for redemption cannot be definitively stated. In
addition, it is difficult to predict whether the Corporation will elect to
exercise such option. However, the Corporation expects that such calls for
redemption will occur.

  From Unused Proceeds

    Subject to compliance with the conditions described under "Senior Asset
Requirement" below, Taxable Auction Rate Series 1998-1 Senior Notes of any
series may, at the Corporation's option, be called for redemption (and shall
be so called for redemption under the circumstances described below), in whole
or in part, and if in part as described under "Selection of Series 1998-1
Notes for Call for Redemption" below, on any regularly scheduled Interest
Payment Date for such series at a Redemption Price of 100% of Principal Amount
of such Notes to be redeemed, plus accrued interest thereon to the Redemption
Date, from proceeds of the Series 1998-1 Notes in the Series 1998-1 Taxable
Acquisition Account that have not been used to acquire Eligible Loans and from
amounts in the Series 1998-1 Taxable Reserve Account.  Such Series 1998-1
Notes shall be so called for redemption on the regularly scheduled Interest
Payment Date for such series in March 1999 (from such proceeds remaining as of
February 1, 1999), unless the Corporation delivers to the Trustee: (i) a
Corporation certificate certifying that, based on a Cash Flow Projection, the
failure to so call Series 1998-1 Notes for redemption will not materially
adversely affect the Corporation's ability to pay Debt Service on the
Outstanding Notes and other Indenture Obligations, Carry-Over Amounts
(including accrued interest thereon) with respect to Outstanding Notes,
Administrative Expenses or Note Fees or to make required deposits to the
Rebate Fund, and (ii) written confirmation from each of the Rating Agencies
then rating the Series 1998-1 Notes to the effect that the failure to call
such Series 1998-1 Notes for redemption will not result in a reduction or
withdrawal of the rating of the Series 1998-1 Notes.  See "Summary of the
Indenture -- Funds and Accounts -- Acquisition Fund" and " -- Reserve Fund".

    Subject to compliance with the conditions described under "Senior Asset
Requirement" below, Tax Exempt Auction Rate Series 1998-1 Senior Notes of any
series may, at the Corporation's option, be called for redemption (and shall
be so called for redemption under the circumstances described below), in whole
or in part, and if in part as described under "Selection of Series 1998-1
Notes for Call for Redemption" below, on any Interest Rate Adjustment Date or
regularly scheduled Interest Payment Date for such series, and (if no Tax
Exempt Auction Rate Series 1998-1 Senior Notes remain Outstanding) Tax Exempt
Fixed Rate Series 1998-1 Notes may, at the Corporation's option, be called for
redemption (and shall be so called for redemption under the circumstances
described below), in whole or in part, and if in part as described under
"Selection of Series 1998-1 Notes for Call for Redemption" below, on any date,
in each case at a Redemption Price of 100% of Principal Amount of such

                                      -52-
<PAGE>
 
Notes to be redeemed, plus accrued interest thereon to the Redemption Date,
from proceeds of the Series 1998-1 Notes in the Series 1998-1 Tax Exempt
Acquisition Account that have not been used to acquire Eligible Loans and from
amounts in the Series 1998-1 Tax Exempt Reserve Account.  Such Series 1998-1
Notes shall be so called for redemption on June 1, 2001 (to the extent the
proceeds remaining in the Series 1998-1 Tax Exempt Acquisition Account exceed
$60,000,000 as of April 15, 2001) and on June 1, 2002 (from such proceeds
remaining as of April 15, 2002), in each case unless the Corporation delivers
to the Trustee:  (i) an opinion of Bond Counsel stating in effect that such
call for redemption is not required pursuant to the Code and that failure to
so call Tax Exempt Series 1998-1 Notes for redemption will not adversely
affect the tax exempt status of interest on any Tax Exempt Series 1998-1 Notes
for federal income tax purposes, (ii) a Corporation certificate certifying
that, based on a Cash Flow Projection, the failure to so call Series 1998-1
Notes for redemption will not materially adversely affect the Corporation's
ability to pay Debt Service on the Outstanding Notes and Other Indenture
Obligations, Carry-Over Amounts (including accrued interest thereon) with
respect to Outstanding Notes, Administrative Expenses or Note Fees or to make
required deposits to the Rebate Fund, and (iii) written confirmation from each
of the Rating Agencies then rating the Series 1998-1 Notes to the effect that
the failure to call such Series 1998-1 Notes for redemption will not result in
a reduction or withdrawal of the rating of the Series 1998-1 Notes.  See
"Summary of the Indenture -- Funds and Accounts -- Acquisition Fund" and " --
Reserve Fund".

Call for Redemption of Series 1998-1 Notes Upon Reduction of Portfolio Balance

    The Series 1998-1 Notes may, at the Corporation's option but subject to
compliance with the conditions described under "Senior Asset Requirement"
below, be called for redemption in whole but not in part, at a Redemption
Price of 100% of Principal Amount, plus accrued interest thereon to the
Redemption Date, on any date when the remaining aggregate outstanding
principal balance of Student Loans Financed with the proceeds of the Series
1998-1 Notes is less than 10% of the amount deposited to the Acquisition Fund
on the Date of Issuance.

OPTIONAL CALL FOR REDEMPTION

    At the Corporation's option but subject to compliance with the conditions
described under "Senior Asset Requirement" below, Auction Rate Series 1998-1
Senior Notes of any series may be called for redemption on any Interest Rate
Adjustment Date or regularly scheduled Interest Payment Date for such series,
in whole or in part, and if in part as described under "Selection of Series
1998-1 Notes for Call for Redemption" below, at a Redemption Price of 100% of
Principal Amount of such Notes to be redeemed, plus accrued interest thereon
to the Redemption Date.

    At the Corporation's option but subject to compliance with the conditions
described under "Senior Asset Requirement" below, Tax Exempt Fixed Rate Series
1998-1 Senior Notes and Tax Exempt Series 1998-1 Subordinate Notes may be
called for redemption on June 1, 2008, or on any date thereafter, in whole or
in part, and if in part as described under "Selection of Series 1998-1 Notes
for Call for Redemption" below, at the following Redemption Prices (expressed
as a percentage of Principal Amount) plus accrued interest to the Redemption
Date:

          June 1, 2010 and thereafter                     100%
</TABLE>

    Notwithstanding the foregoing, no Series 1998-1 Notes shall be so called
for redemption unless the Trustee receives a Corporation certificate
certifying that, based on a Cash Flow Projection, such redemption will not
materially adversely affect the Corporation's ability to pay Debt Service on
the Outstanding Notes and other

                                      -53-
<PAGE>
 
Indenture Obligations, Carry-Over Amounts (including accrued interest thereon)
with respect to Outstanding Notes, Administrative Expenses or Note Fees or to
make required deposits to the Rebate Fund.

SELECTION OF SERIES 1998-1 NOTES FOR CALL FOR REDEMPTION

    If less than all Outstanding Series 1998-1 Notes are to be called for
redemption, the Principal Amounts of each series of Series 1998-1 Notes to be
called for redemption shall be selected as follows, to the extent that the
provisions of the Indenture described under "Senior Asset Requirement" below
will not be violated thereby:  either (1) except as otherwise specifically
provided above under "Special Call for Redemption" or as described in clause
(2), to the extent Series 1998-1 Subordinate Notes are subject to call for
redemption, that Principal Amount thereof shall be called for redemption which
bears, as nearly as practicable, the same proportion to the Principal Amount
of all Series 1998-1 Notes to be called for redemption as the aggregate
Principal Amount of Outstanding Series 1998-1 Subordinate Notes bears to the
aggregate Principal Amount of all Outstanding Series 1998-1 Notes, or (2) if
the Trustee receives a Corporation certificate certifying that, based on a
Cash Flow Projection, a different proportion of Series 1998-1 Subordinate
Notes to be called for redemption will not materially adversely affect the
Corporation's ability to pay Debt Service on the Outstanding Notes and other
Indenture Obligations, Carry-Over Amounts (including accrued interest thereon)
with respect to Outstanding Notes, Administrative Expenses or Note Fees or to
make required deposits to the Rebate Fund, Series 1998-1 Subordinate Notes
shall be called for redemption in such principal amount as is designated by
the Corporation in such certificate.  The remaining Series 1998-1 Notes to be
called for redemption on a given Redemption Date shall be selected from the
appropriate series of Series 1998-1 Senior Notes.

    If less than all Outstanding Series 1998-1 Senior Notes subject to call
for redemption are to be called for redemption, and more than one series of
Series 1998-1 Senior Notes is so subject, the Principal Amounts of each series
of Series 1998-1 Notes to be called for redemption shall be selected from each
such series in such Principal Amounts as the Corporation may designate or, in
the absence of such designation, from each such series in, as nearly as
practicable, the same proportion to the aggregate Principal Amount of all
Outstanding Series 1998-1 Senior Notes to be called for redemption as the
aggregate Principal Amount of Outstanding Series 1998-1 Senior Notes of such
series bears to the aggregate Principal Amount of all Outstanding Series
1998-1 Senior Notes subject to such call for redemption. Notwithstanding the
foregoing, if Series 1998-1 Subordinate Notes cannot be called for redemption
due to the application of the provisions of the Indenture described under
"Senior Asset Requirement" below, but Series 1998-1 Senior Notes can be called
for redemption without violating such provisions, the particular Series 1998-1
Notes to be called for redemption shall be selected from the appropriate
series of the Series 1998-1 Senior Notes according to the provisions described
above.

    If less than all of the Outstanding Series 1998-1 Notes of a given series
are to be called for redemption, the particular Series 1998-1 Notes to be
called for redemption shall be selected by the Trustee by lot in such manner
as the Trustee shall deem fair and appropriate and which may provide for the
selection for call for redemption of portions of the principal of Series
1998-1 Notes in authorized denominations.

SENIOR ASSET REQUIREMENT

    No call for redemption or prepayment of any Series 1998-1 Note under any
of the foregoing provisions is to be made unless, after giving effect to the
call for redemption or prepayment:  (a) in the case of the call for redemption
or prepayment of Series 1998-1 Senior Notes, either the Senior Asset
Requirement will be met or the Senior Percentage will be greater than it would
have been without such call for redemption or prepayment, and (b) in the case
of the call for redemption or prepayment of Series 1998-1 Subordinate Notes,
the Senior Asset Requirement will be met.  Compliance with the Senior Asset
Requirement will be determined as of the date of the selection of Series
1998-1 Notes to be called for redemption or as of the date on which moneys are
transferred to the Retirement Account to make any prepayment of Taxable LIBOR
Rate Series 1998-1 Notes, as the case may be,

                                      -54-
<PAGE>
 
and any failure to meet the Senior Asset Requirement as of the Redemption Date
or prepayment date, as applicable, will not affect such determination.  In
general, the "Senior Asset Requirement" requires that the Senior Percentage is
at least 110% and the Subordinate Percentage is at least 100%, although each
such percentage may be lowered under the conditions prescribed in the
Indenture.  See "Glossary of Certain Defined Terms" and "Summary of the
Indenture -- Call for Redemption, Prepayment or Purchase of Notes; Senior
Asset Requirement".

NOTICE AND EFFECT OF CALL FOR REDEMPTION

    Notice of call for redemption of the Series 1998-1 Notes shall be given by
first class mail, mailed not less than 15 days (in the case of Auction Rate
Series 1998-1 Senior Notes) or 30 days (in the case of any other Series 1998-1
Notes), as the case may be, prior to the date fixed for redemption to each
Holder (which initially will be DTC or its nominee) of Series 1998-1 Notes to
be called for redemption at the address of such Holder appearing in the Note
Register; but no defect in or failure to give such mailed notice of call for
redemption shall affect the validity of proceedings for the redemption of any
Series 1998-1 Note not affected by such defect or failure.  All notices of
call for redemption shall state:  (i) the Redemption Date; (ii) the Redemption
Price; (iii) the name, Stated Maturity and CUSIP numbers of the Series 1998-1
Notes to be called for redemption, the principal amount of Series 1998-1 Notes
of each series to be called for redemption, and, if less than all Outstanding
Notes of such series are to be called for redemption, the identification (and,
in the case of partial redemption, the respective principal amounts) of the
Series 1998-1 Notes to be called for redemption; (iv) that, on the Redemption
Date, the Redemption Price of and accrued interest on each such Series 1998-1
Note will become due and payable and interest thereon shall cease to accrue on
and after such date; (v) the place or places where such Series 1998-1 Notes
are to be surrendered for payment of the Redemption Price thereof and accrued
interest thereon; and (vi) if it be the case, that such Series 1998-1 Notes
are to be called for redemption by the application of certain specified trust
moneys and for certain specified reasons.

    Notice of call for redemption having been given as provided above, the
Series 1998-1 Notes designated in such notice shall become due and payable at
the applicable Redemption Price, plus interest accrued thereon to the
Redemption Date, and, upon surrender in accordance with such notice, shall be
so paid, and thereafter such Series 1998-1 Notes shall cease to accrue
interest.

    No such notice shall be required with respect to prepayments of the
Taxable LIBOR Rate Series 1998-1 Notes as described above under "Prepayment of
Taxable LIBOR Rate Series 1998-1 Notes."

APPLICATION OF SERIES 1998-1 NOTE PROCEEDS

    The Original Issuer and the Corporation intend to use the proceeds of the
sale of the Series 1998-1 Notes in the following amounts for the following
purposes:

         (1) $332,170,000 will be deposited in the Series 1998-1 Tax Exempt
Acquisition Account and used as follows:

              (a)  approximately $87,070,000 will be used on the Date of
         Issuance to refinance approximately $85,760,000 aggregate principal
         amount of Eligible Loans previously acquired or originated by the
         Original Issuer; and

              (b)  the remainder will be used to acquire or originate
         additional Eligible Loans;

         (2) $572,820,000 will be deposited in the Series 1998-1 Taxable
Acquisition Account and used as follows:

                                      -55-
<PAGE>
 
              (a)  approximately $507,720,000 will be used on the Date of
         Issuance to refinance approximately $500,870,000 aggregate principal
         amount of Eligible Loans previously acquired or originated by or on
         behalf of the Original Issuer; and

              (b)  the remainder will be used to acquire or originate
         additional Eligible Loans; and

         (3) $18,480,000 will be deposited in the Reserve Fund.

    It is expected that immediately after the deposit of the proceeds of the
Series 1998-1 Notes as described above, the principal amount of, and accrued
interest on and Special Allowance Payments with respect to, Financed Eligible
Loans, together with the remaining proceeds in the Acquisition Fund and the
Balance in the Reserve Fund, will equal 100% of the principal amount of the
Series 1998-1 Notes.

    The characteristics as of December 31, 1997 of the Eligible Loans expected
to be Financed on the Date of Issuance with proceeds deposited to the Series
1998-1 Tax Exempt Acquisition Account and to the Series 1998-1 Taxable
Acquisition Account (aggregating approximately $590 million as of that date)
are more particularly described under "Characteristics of the Initial Financed
Eligible Loans."  These Eligible Loans currently secure outstanding
obligations of the Original Issuer used to acquire such Student Loans, which
will be refunded from the proceeds of the Series 1998-1 Notes .

    The Corporation expects the remaining proceeds deposited to the Series
1998-1 Tax Exempt Acquisition Account (approximately $245,100,000 or 27% of
the Series 1998-1 Note proceeds) to be used to purchase Eligible Loans (see
"Glossary of Certain Defined Terms") from Lenders or to originate Eligible
Loans on or before April 15, 2002, approximately according to the following
schedule:

<TABLE>

                      2002                        37.2
</TABLE>

At the Corporation's option, or if not expended as of certain dates, such
proceeds may be transferred to the Retirement Account and used to redeem Tax
Exempt Auction Rate Series 1998-1 Senior Notes which are called for redemption
and, if no Tax Exempt Auction Rate Series 1998-1 Senior Notes remain
Outstanding, Tax Exempt Fixed Rate Series 1998-1 Notes which are called for
redemption.  See "Description of Series 1998-1 Notes -- Special Call for
Redemption -- From Unused Proceeds" herein.  Investors holding such Tax Exempt
Series 1998-1 Notes (particularly Tax Exempt Fixed Rate Series 1998-1 Notes)
which are called for redemption may be unable to reinvest the proceeds of the
redemption at the same yield as the Tax Exempt Series 1998-1 Notes.  Also,
depending on the price at which investors purchased such Series 1998-1 Notes,
their yield may be adversely affected by such early call for redemption.

    The Corporation expects the remaining proceeds deposited to the Series
1998-1 Taxable Acquisition Account (approximately $65,100,000 or 7% of the
Series 1998-1 Note proceeds) to be used to purchase Eligible Loans from
Lenders or to originate Eligible Loans on or before February 1, 1999.  At the
Corporation's option, or if not expended as of February 1, 1999, such proceeds
may be transferred to the Retirement Account and used to redeem Taxable
Auction Rate Series 1998-1 Senior Notes which are called for redemption.  See
"Description of Series 1998-1 Notes -- Special Call for Redemption -- From
Unused Proceeds" herein.  Investors holding such Taxable Auction Rate Series
1998-1 Senior Notes which are called for redemption may be unable to reinvest
the

                                      -56-
<PAGE>
 
proceeds of the redemption at the same yield as the Taxable Auction Rate
Series 1998-1 Senior Notes.  Also, depending on the price at which investors
purchased such Series 1998-1 Notes, their yield may be adversely affected by
such early call for redemption.

    For a more detailed description of the Original Issuer's programs of
Financing Eligible Loans (which will be continued by SLFC on behalf of the
Corporation pursuant to the Servicing Agreement), Eligible Loans expected to
be Financed after the Date of Issuance, and possible limitations on the
expenditure of these proceeds as expected, see "Description of Financed
Eligible Loan Program."  Use of the moneys in the Acquisition Fund pending
Financing of Eligible Loans is more particularly described in "Summary of the
Indenture -- Funds and Accounts -- Acquisition Fund."

    Balances in the Acquisition Fund representing proceeds of the Series
1998-1 Notes not used to acquire Eligible Loans on the Date of Issuance, and
Balances in the Reserve Fund, are expected to be used to acquire one or more
investment agreements meeting the requirements of the Indenture.  Each
investment agreement will require the Investment Provider (a financial
institution to which such proceeds are loaned) to repay such proceeds when
requested by the Corporation or the Trustee (subject to such limitations as
may be provided therein), and to pay interest on such proceeds periodically.
Each Investment Provider will be a party which meets the Rating Agencies'
criteria for creditworthiness or which has pledged collateral satisfactory to
the Rating Agencies to secure its repayment obligations. See "Summary of the
Indenture -- Investments".

    Although the Corporation expects that the investment return on the
Balances in the Acquisition Fund pending its use to finance Eligible Loans,
together with other Pledged Revenues and Pledged Funds and Accounts (each as
defined in "Source of Payment and Security for the Notes -- General") under
the Indenture (including Financed Eligible Loans), will be sufficient to meet
principal and interest payments on the Series 1998-1 Notes and required
expenses under the Indenture, various risk factors could adversely affect that
expectation. See "Risk Factors."

    The Costs of Issuance of the Series 1998-1 Notes will be paid by the
Original Issuer from other moneys available therefor.


                 SOURCE OF PAYMENT AND SECURITY FOR THE NOTES

GENERAL

    The Notes will be limited obligations of the Corporation payable solely
from the Trust Estate created under the Indenture, consisting of certain
revenues ("Pledged Revenues") and Funds and Accounts pledged under the
Indenture (the "Pledged Funds and Accounts", which do not include the Rebate
Fund).  The Pledged Revenues include: (i) payments of interest and principal
made by obligors of Financed Student Loans, (ii) Guarantee Payments made by
the Guarantee Agencies to or for the account of the Trustee as the holder of
defaulted Financed Student Loans, (iii) interest subsidy payments and Special
Allowance Payments made by the Department of Education to or for the account
of the Trustee as the holder of Financed Student Loans (excluding, except in
the case of the Eligible Loans to be Financed on the Date of Issuance, any
Special Allowance Payments and interest subsidy payments accrued prior to the
date of Financing the related Student Loan), (iv) income from investment of
moneys in the Pledged Funds and Accounts (except to the extent such income is
required to be deposited in the Rebate Fund), (v) payments from a Swap
Counterparty under a Swap Agreement, (vi) proceeds of any sale or assignment
by the Corporation of any Financed Student Loans, and (vii) available Note
proceeds.  In addition, the Pledged Revenues with respect to one or more
series of Notes may include payments made by a Credit Facility Provider
pursuant to a Credit Enhancement Facility.  No Credit Enhancement Facility or
Swap Agreement is being delivered in connection with the issuance of the
Series 1998-1 Notes, and it is not expected that any such revenues will be
available to pay the Series 1998-1 Notes.

                                      -57-
<PAGE>
 
    The principal of, premium, if any, and interest on the Notes will be
secured by a pledge of and a security interest in all rights, title, interest
and privileges of the Corporation (1) with respect to Financed Student Loans,
in, to and under any Servicing Agreement, the Student Loan Purchase
Agreements, the Guarantee Agreements and the Federal Reimbursement Contracts;
(2) in, to and under all Financed Student Loans (including the evidences of
indebtedness thereof and related documentation), any Swap Agreement and
(subject to the limitations therein or in the Indenture limiting the benefits
thereunder to the Notes of one or more series) any Credit Enhancement
Facility; and (3) in and to the proceeds from the sale of the Notes (until
expended for the purpose for which issued) and the Pledged Revenues, moneys,
evidences of indebtedness and securities in the Pledged Funds and Accounts.
The security interest in revenues, moneys, evidences of indebtedness and,
unless registered in the name of the Trustee, securities payable into the
various Funds and Accounts does not constitute a perfected security interest
until received by the Trustee. Certain Pledged Revenues are subject to
withdrawal from the Pledged Funds and Accounts, to prior applications to pay
Costs of Issuance, Administrative Expenses and Note Fees, and to certain other
applications as described under "Description of Flow of Revenues in the Funds"
below and "Summary of the Indenture -- Funds and Accounts".

ADDITIONAL INDENTURE OBLIGATIONS

    The Indenture provides that, upon the satisfaction of certain conditions,
the Corporation may issue one or more series of Additional Notes thereunder.
(Any Additional Notes will not be offered or sold pursuant to this
Prospectus.)  Additional Notes may be issued as Senior Notes on a parity basis
with the Series 1998-1 Senior Notes; as Subordinate Notes on a parity basis
with the Series 1998-1 Subordinate Notes; or as Class C Notes on a subordinate
basis to the Senior Notes and the Subordinate Notes.  In addition, the
Corporation may enter into Swap Agreements and may obtain Credit Enhancement
Facilities from one or more Credit Facility Providers.  The Corporation's
obligations under the Swap Agreements, and its obligations to pay the premiums
or fees of Credit Facility Providers and, if applicable, to reimburse payments
made under Credit Enhancement Facilities, may be parity obligations with the
Senior Notes (such Other Senior Obligations, together with the Senior Notes,
being referred to herein as Senior Obligations) or parity obligations with the
Subordinate Notes (such Other Subordinate Obligations, together with the
Subordinate Notes, being referred to herein as Subordinate Obligations).  The
Senior Obligations, the Subordinate Obligations, and any Class C Notes are
referred to herein as "Indenture Obligations".  See "Summary of the Indenture
- -- Additional Notes" and "-- Covenants -- Credit Enhancement Facilities and
Swap Agreements".

    Under the Indenture, the Corporation may not execute a Swap Agreement
unless the Swap Counterparty's obligations are rated by each Rating Agency not
lower than in its third highest Specific Rating Category.  No Swap Agreement
shall be a Senior Obligation unless, as of the date the Corporation enters
into such Swap Agreement, the Senior Asset Requirement will be met and the
Trustee shall have received written confirmation from each Rating Agency that
the execution and delivery of the Swap Agreement will not cause the reduction
or withdrawal of any rating or ratings then applicable to any Outstanding
Notes.  No Swap Agreement is being entered into in connection with the
issuance of the Series 1998-1 Notes.

    No limitations are imposed by the Indenture on the ability of the
Corporation to obtain Credit Enhancement Facilities or to enter into
agreements with respect thereto, or as to the identity or creditworthiness of
any Credit Facility Provider.  Any Credit Enhancement Facility may be obtained
for the sole benefit of the series of Notes designated therein, in which event
payments under such Credit Enhancement Facility would not be available for the
payment of principal of, premium, if any, or interest on any other series of
Notes.  However, any payments required to be made to any Credit Facility
Provider would be parity obligations with the other Senior Obligations or
Subordinate Obligations, as the case may be, payable from any revenues
available to pay such Indenture Obligations.  No Credit Enhancement Facility
is being entered into in connection with the issuance of the Series 1998-1
Notes and it is not expected that any Credit Enhancement Facility which may be
obtained would be for the benefit of the Series 1998-1 Notes.

                                      -58-
<PAGE>
 
    The Indenture also permits the Corporation to issue Class C Notes from
time to time upon satisfaction of the conditions specified therein.  See
"Summary of the Indenture -- Additional Notes".

PRIORITIES

    The Series 1998-1 Senior Notes (and any other Senior Obligations) are
entitled to payment and certain other priorities over the Series 1998-1
Subordinate Notes (and any other Subordinate Obligations).  Current payments
of interest and principal due on the Subordinate Notes on an Interest Payment
Date or Principal Payment Date will be made (on a parity basis with any other
Subordinate Obligations) only to the extent there are sufficient moneys
available for such payment, after making all such payments due on such date
with respect to Senior Obligations.  So long as any Senior Obligations remain
Outstanding under the Indenture, the failure to make interest or principal
payments with respect to Subordinate Notes (including the Series 1998-1
Subordinate Notes) will not constitute an Event of Default under the
Indenture.  In the event of an acceleration of the Notes, the principal of and
accrued interest on the Subordinate Notes will be paid (on a parity basis with
any other Subordinate Obligations) only to the extent there are moneys
available under the Indenture after payment of the principal of, and accrued
interest on, all Senior Notes and the satisfaction of all other Senior
Obligations.  In addition, holders of Senior Notes and Beneficiaries of other
Senior Obligations are entitled to direct certain actions to be taken by the
Trustee prior to and upon the occurrence of an Event of Default, including
election of remedies.  See "Summary of the Indenture -- Remedies".

    Senior Obligations and Subordinate Obligations are entitled to payment and
certain other priorities over any Class C Notes.  Principal of and interest on
the Class C Notes are not payable from moneys in the Note Fund or the Reserve
Fund, but are payable solely from amounts available therefor in the Surplus
Fund.  See "Summary of the Indenture -- Funds and Accounts -- Surplus Fund".

DESCRIPTION OF FLOW OF REVENUES IN THE FUNDS

    The Indenture establishes a Revenue Fund which is divided into a Repayment
Account and an Income Account. Except for certain amounts received with
respect to Financed Student Loans required to be credited to the Surplus Fund,
the Indenture requires the deposit into the Revenue Fund of (i) all amounts
received as principal and interest in repayment of Financed Student Loans,
including all federal interest subsidy payments, Guarantee Payments and
Special Allowance Payments received with respect to each Financed Student Loan
(excluding, except in the case of the Eligible Loans to be Financed on the
Date of Issuance, Special Allowance Payments and federal interest subsidy
payments that accrued prior to the date on which such Student Loans were
Financed), (ii) except as otherwise provided in a Supplemental Indenture,
proceeds of the resale to a Lender of any Financed Student Loans pursuant to
the Lender's repurchase obligation under the applicable Student Loan Purchase
Agreement, (iii) all amounts received as earnings on or income from Investment
Securities in the Revenue Fund, the Surplus Fund, the Reserve Fund, the
Administration Fund and the Note Fund, and (iv) any amounts permitted to be
transferred to the Revenue Fund from the Rebate Fund.  The Trustee is required
to credit all such revenues received as payments of principal of Financed
Student Loans to the Repayment Account, and to credit all other such revenues
and amounts (including revenues received as payments of interest on or Special
Allowance Payments with respect to Financed Student Loans and income from
Investment Securities) to the Income Account. The Indenture requires the
Trustee to transfer moneys on a monthly basis (after taking into account any
periodic rebate fee payment required to be made in respect of Student Loans
Financed under the Indenture), first from the Repayment Account and then from
the Income Account, to the following Funds and Accounts in the following
order: the Rebate Fund, the Interest Account for the payment of Senior
Obligations, the Principal Account for the payment of Senior Obligations, the
Retirement Account for the redemption of Senior Notes which are called for
redemption, the Interest Account for the payment of Subordinate Obligations,
the Principal Account for the payment of Subordinate Obligations, the
Retirement Account for the redemption of Subordinate Notes which are called
for redemption, the Administration Fund (but only from the Income Account),
the Reserve Fund, the Principal Account (relating to cumulative sinking fund
installments with respect to Subordinate Term Notes which are called for
redemption on a Sinking Fund Payment Date), the Special Redemption and
Prepayment Account and the Surplus Account.  In

                                      -59-
<PAGE>
 
addition, any amounts payable by a Swap Counterparty pursuant to a Swap
Agreement are required to be credited directly to the Interest Account.

    Moneys in the Administration Fund may be used, as provided in the
Indenture, to pay Costs of Issuance, Note Fees and Administrative Expenses.

    Balances in the Surplus Fund shall be used first to make up deficiencies
in, or make required transfers to, the Rebate Fund, the Note Fund, the
Administration Fund and the Reserve Fund.  Balances in the Surplus Fund may
also be applied, as determined by the Corporation from time to time, to the
payment of principal of or interest on Class C Notes when due or upon the call
thereof for redemption at the option of the Corporation; provided that the
conditions described under "Summary of the Indenture -- Funds and Accounts --
Surplus Fund" are met.

    If the Trustee shall have first certified that no deficiencies exist in
any of the Rebate Fund, the Note Fund, the Reserve Fund or the Special
Redemption and Prepayment Account, and shall have received certain
certifications from the Corporation, Balances in the Surplus Account may be
used to redeem Notes which are called for redemption (including Series 1998-1
Notes as described under "Description of Series 1998-1 Notes -- Special Call
for Redemption -- From Moneys in the Surplus Account") or to purchase Notes or
may be: (a) used to acquire Student Loans meeting the requirements of clauses
(A) (1) and (2) or clause (B) of the definition of "Eligible Loans" (see
"Glossary of Certain Defined Terms"); or (b) released from the Indenture to be
used for certain other authorized purposes; provided, however, that the
Indenture prohibits the use of the Surplus Account to acquire Student Loans
that are not Eligible Loans and for the purposes specified in clause (b) above
unless, after taking into account any such application (i) the Senior
Percentage will be not less than 112%, and (ii) the Subordinate Percentage
will be not less than 102%; provided that such percentages may be lower upon
receipt of certain approvals from each Rating Agency and, under certain
circumstances, consent of Other Beneficiaries.

    The Indenture establishes a Rebate Fund into which the Trustee is
required to make annual deposits from Balances in the Revenue Fund, the
Surplus Fund, the Reserve Fund, the Administration Fund, the Bond Fund and the
Acquisition Fund, in that order, equal to the amount computed under Section
148(f) of the Code as being subject to rebate to the United States (the
"Rebate Amount") and certain amounts constituting Excess Earnings on the
Financed Student Loans.  The Trustee is required to pay to the United States
Treasury, at least once every five years, an amount which ensures that not
less than 90% of the cumulative Rebate Amount will have been paid to the
United States Treasury.  The Trustee is required to consult with Bond Counsel
and take such action as may be required under the Code (which may include
forgiveness of principal of Financed Student Loans or payments to the United
States Treasury) with respect to Excess Earnings.  Under certain
circumstances, including delivery to the Trustee of a favorable opinion of
Bond Counsel, certain amounts determined not to be subject to rebate or other
disposition may be transferred from the Rebate Fund to the Income Account.

    Balances in the Reserve Fund shall be used and applied solely for the
purpose of paying Debt Service on the Senior Notes and the Subordinate Notes,
paying net amounts due with respect to other Senior Obligations or Subordinate
Obligations or for transfer to the Rebate Fund to the extent provided in the
Indenture.

    For a more detailed description of the receipt and application of moneys
in the Revenue Fund, the Acquisition Fund, the Note Fund, the Rebate Fund, the
Reserve Fund, the Administration Fund and the Surplus Fund, see "Summary of
the Indenture -- Funds and Accounts".


                             THE ORIGINAL ISSUER

    The Original Issuer is a South Dakota nonprofit corporation organized in
December 1978, at the request of the then Governor of the State, to provide a
statewide student loan acquisition program pursuant to the provisions of the
Higher Education Act and Section 150(d) of the Code.  Former Governor Wollman
designated the Original Issuer as the single nonprofit private agency in the
State acting as an eligible lender in connection with the student

                                      -60-
<PAGE>
 
loan program provided for by the Higher Education Act.  The Original Issuer
has received an Internal Revenue Service determination that, based on its
original organization and purposes, it is a tax-exempt organization under
Section 501(c)(3) of the Code.

    As required by Section 150(d) of the Code, the Original Issuer's Articles
of Incorporation provide that the Original Issuer is organized exclusively for
the purpose of acquiring student loan notes incurred under the Higher
Education Act, and that income of the Original Issuer may be used only for:
(i) the payment of expenses and debt service on bonds or notes issued by the
Original Issuer or the creation of reserves for such purposes; (ii) the
acquisition of additional student loan notes; or (iii) payment to the United
States.  In connection with an election under Section 150(d)(3) of the Code to
terminate its status as a corporation described in Section 150(d), the
Original Issuer will enter into an agreement with Student Loan Finance
Corporation, a newly organized South Dakota corporation and wholly-owned
subsidiary of the Original Issuer ("SLFC"), pursuant to which the Original
Issuer will transfer all of its student loans (including its rights in
Financed Student Loans), student loan acquisition and servicing operations and
physical facilities, together with certain other assets (including the
Original Issuer's interest in the other assets comprising the Trust Estate),
to SLFC and SLFC will assume all of the Original Issuer's obligations with
respect to the Notes, the Indenture, the Trust Estate and all related
contracts.  See "The Servicer" herein.   The Original Issuer will transfer
such assets without recourse, and will be released from all obligations under
the Indenture or otherwise with respect to the Notes.  Concurrently with such
transfer, the Original Issuer will amend its articles of incorporation to
amend its corporate purpose and change its name to Great Plains Education
Foundation, Inc.  Under Section 150(d)(3) of the Code, the Original Issuer
must continue to be an organization described in Section 501(c)(3) of the
Code.  No determination has been received from the Internal Revenue Service as
to the Original Issuer's qualification as an organization described in Section
501(c)(3) of the Code after the amendment of its articles of incorporation.

    Immediately upon such transfer, SLFC will transfer all its rights and
interest in the Financed Student Loans and other assets of the Trust Estate to
the Corporation, which is a newly organized, bankruptcy-remote, limited
purpose Delaware corporation and wholly-owned subsidiary of SLFC, and the
Corporation will assume all of SLFC's obligations under the Indenture and
otherwise with respect to the Notes, the Trust Estate and the related
contracts.  SLFC will also transfer such assets without recourse, and will be
released from all obligations under the Indenture or otherwise with respect to
the Notes (except in its capacity as Servicer).  Neither the Original Issuer
nor SLFC (except in its capacity as Servicer) will be obligated under the
Indenture.


                                 THE SERVICER

GENERAL

    SLFC will be a newly organized South Dakota corporation.  In connection
with the Original Issuer's election under Section 150(d)(3) of the Code, all
of the assets of the Original Issuer used in its business of acquiring,
originating, holding, servicing and collecting student loans, including its
physical facilities, computer hardware and software, and certain other assets
will be transferred to SLFC.  At that time, all of the Original Issuer's
employees are expected to become employees of SLFC.  Immediately after such
transfer, SLFC expects to operate the student loan business formerly operated
by the Original Issuer and service and collect the Financed Eligible Loans in
substantially the same manner (including using the same staff, offices and
computer hardware and software) in which the Original Issuer currently
administers its program and services and collects such loans.

    The Original Issuer has operated as a secondary market for student loans
since 1979.  As of December 31, 1997, the Original Issuer had a staff of 88
persons.  The Original Issuer services the student loans which it owns and has
also from time to time serviced student loans owned by other lenders in
anticipation of sale to the Original Issuer.  The Original Issuer utilizes its
own computer hardware and software systems designed specifically for student
loan servicing.  The Original Issuer installed the original hardware in 1979
and since then has added additional hardware or replaced hardware as needed.
As of December 31, 1997, the Original Issuer owned and was

                                      -61-
<PAGE>
 
servicing student loans to approximately 91,600 borrowers representing
approximately $590 million outstanding principal amount of student loans.  As
of such date, the Original Issuer also was servicing student loans held by
other lenders representing less than $3 million outstanding principal amount.

    The Original Issuer has financed its acquisition of student loans through
the issuance of its student loan revenue bonds, student loan asset-backed
notes and other evidences of indebtedness.  The Original Issuer has issued
approximately $2.25 billion aggregate principal amount of bonds and notes, of
which $912,425,000 principal amount were outstanding as of December 31, 1997.
All of such outstanding bonds and notes will be refunded with a portion of the
proceeds of the Series 1998-1 Notes.  After the transfer of the assets
described above to SLFC, the Original Issuer expects to participate in various
aspects of the student loan business, but cease its participation in the
Federal Family Education Loan Program.

    The information included above concerning the Original Issuer has been
included solely to describe the expected future operations of SLFC.  The
Original Issuer will not transfer all of its cash and investments to SLFC.
None of the assets retained by the Original Issuer will be available to SLFC
or for the payment of the Notes.  The Original Issuer will have no obligation
with respect to (i) the Financed Eligible Loans or the servicing thereof, (ii)
the payment of the Series 1998-1 Notes, or (iii) the administration of the
Indenture.  Moreover, the Original Issuer's transfer of assets to SLFC will be
without recourse or warranty.  Thus, in the event of a failure of the Original
Issuer's hardware and software systems to adequately function, or any other
factor which adversely affects the value of the assets transferred to SLFC or
SLFC's ability to perform its obligations under the SLFC Servicing Agreement,
the Original Issuer would have no obligation or liability with respect
thereto.

DELINQUENCY AND LOAN LOSS EXPERIENCE

    The following tables provide information regarding the delinquency status
of the student loan portfolio of the Original Issuer (which has been serviced
by the Original Issuer) as of June 30, 1997, 1996, 1995, 1994 and 1993.  For
each delinquency status listed (based on number of days delinquent and claims
filed), the tables show the aggregate principal amount of Student Loans in
each delinquency status as of each date; the percent of the aggregate
principal amount of the Original Issuer's Student Loan portfolio in repayment,
deferment, forbearance and claims status as of each date represented by such
principal amounts; and the percent of the aggregate principal amount of the
Original Issuer's entire Student Loan portfolio as of each date represented by
such principal amounts.  The Original Issuer's management believes that the
distribution of delinquent loans in the Original Issuer's Student Loan
portfolio has been consistent over the last five years and it is unaware of
any current trends that are expected to materially alter such distributions or
materially impact the future performance of the Financed Eligible Loans.
Notwithstanding the above, no assurance can be made that any such trends will
continue or not deteriorate.

    The following tables provide information regarding principal losses
relating to the Original Issuer's Student Loan portfolio (which has been
serviced by the Original Issuer) for each of the years ended June 30, 1993
through 1997.  The first table shows the aggregate principal amount of losses
during each period, and the breakdown of such losses between the amount
representing the two percent portion of default claims filed with a Guarantee
Agency which is not paid by the Guarantee Agency with respect to loans made
after September 30, 1993, and the amount representing other principal
write-offs (i.e., for loans that may have lost Guarantee eligibility) net of
recoveries.  The second table shows the percent of the Original Issuer's
entire Student Loan portfolio end-of-period balances represented by the
aggregate losses listed in the first table during the relevant period.

    Subject to compliance with Department of Education and Guarantee Agency
requirements, student loans made under the Federal Family Education Loan
Program prior to October 1, 1993 are entitled to 100% guarantee coverage for
defaulted loans while student loans made on or after that date are entitled to
98% coverage.  The

                                      -63-
<PAGE>
 
Original Issuer's management expects that overall write-offs of the portfolio
related to this two percent difference will increase over time as a greater
percentage of the portfolio consists of loans made on or after October 1,
1993.

    Other write-offs arise if a claim is rejected by the Guarantee Agency, and
the Original Issuer determines that the reason for the rejection cannot be
cured, that the Lender from which the loan was acquired cannot or should not
be required to repurchase the loan, and that the loan is otherwise not
collectible.  The Original Issuer's management believes that the amount of
other write-offs during this period has been consistent and immaterial and it
is unaware of any current trends that are expected to materially alter the
loss experience or materially impact the future performance of the Financed
Eligible Loans.  Notwithstanding the above, no assurance can be made that any
such trends will continue or not deteriorate.

                               THE CORPORATION

GENERAL

     The Corporation is a newly organized, bankruptcy remote, limited purpose
Delaware corporation and a wholly owned subsidiary of SLFC.  Immediately
following the issuance of the Series 1998-1 Notes, the Corporation will assume
all of SLFC's obligations under the Indenture and otherwise with respect to
the Notes, the Trust Estate and the related contracts.

     As a bankruptcy-remote entity, the Corporation's operations will be
restricted so that (i) it does not engage in business with, or incur
liabilities to, any other entity (other than the Noteholders and Other
Beneficiaries, and beneficiaries under indentures similar to the Indenture)
which may bring bankruptcy proceedings against the Corporation, and (ii) the
risk that it will be consolidated into the bankruptcy proceedings of any other
entity is diminished.  The Corporation has covenanted in the Indenture that it
will not engage in any business other than financing, originating, purchasing,
owning, selling and managing Student Loans in the manner contemplated by its
certificate of incorporation and the Indenture and the activities incidental
thereto.

     The Corporation will have no substantial assets other than those
transferred to it from SLFC and pledged under the Indenture.  The Corporation
will have no full-time employees.  Certain responsibilities of the Corporation
under the Indenture will be administered by SLFC.  See "The SLFC Servicing
Agreement" and "Certain Relationships Among Financing Participants."

     The Corporation's address is 105 First Avenue Southwest, Aberdeen, South
Dakota 57401 and its phone number is (605) 622-4400.

FINANCED ELIGIBLE LOAN PROGRAM

     The Corporation will, upon the Section 150(d)(3) Transfer and the
assumption of the Original Issuer's obligations under the Indenture, become
responsible for the acquisition or origination of Eligible Loans to be
Financed with proceeds of the Series 1998-1 Notes deposited to the credit of
the Acquisition Fund.  In this regard, as of December 31, 1997, the
Corporation has entered into Student Loan Purchase Agreements with
approximately 95 Lenders providing for the purchase of approximately $194
million in principal amount of Eligible Loans from moneys available therefor
in the Series 1998-1 Tax Exempt Acquisition Account and Student Loan Purchase
Agreements (which do not provide for the purchase of a stated principal amount
of Eligible Loans) with approximately 85 Lenders providing for the purchase of
Eligible Loans from moneys available therefor in the Series 1998-1 Taxable
Acquisition Account.  As further described under "Description of Financed
Eligible Loan Program -- Background of the Original Issuer's Program", the
Original Issuer has historically entered into comparable agreements with
Lenders (including substantially all of the Lenders with which the Corporation
has current agreements) pursuant to which the Original Issuer has purchased
over $1.29 billion in Student Loans from proceeds of its bonds and notes in
the same manner as the Corporation intends to purchase Eligible Loans from
proceeds of the Series 1998-1 Notes.  Thus, the Corporation anticipates that
it will be able to apply all, or substantially all, of the proceeds of the
Series 1998-1 Notes to the acquisition or origination of Eligible Loans.  See
"Description of Financed Eligible Loan Program".  However, there is no
assurance that the Corporation will be able to so apply such proceeds.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL
CONDITION

     As of the date of this Prospectus, the Corporation has had no operating
history.  The proceeds of the sale of the Series 1998-1 Notes will be used
primarily to refinance a portfolio of Student Loans currently owned by the
Original Issuer and to purchase Eligible Loans from Lenders or to originate
Eligible Loans on or before April 15, 2002.  See "Application of Series 1998-1
Note Proceeds."  The Corporation is prohibited by its certificate of
incorporation from engaging in any business other than (i) receiving the
assets and assuming the liabilities

                                      -65-
<PAGE>
 
transferred to it in connection with the Original Issuer's election under
Section 150(d)(3) of the Code; (ii) originating or acquiring Student Loans;
(iii) entering into certain agreements relating to Student Loans; (iv) issuing
bonds, notes, asset-backed certificates or other securities payable solely
from Student Loans and other assets pledged to the payment thereof; and (v)
engaging in acts incidental to and necessary, suitable or convenient for the
accomplishment of the foregoing purposes and permitted under Delaware law. The
Corporation's ability to incur, assume or guarantee indebtedness for borrowed
money is also restricted by its certificate of incorporation.

DIRECTORS AND EXECUTIVE OFFICER

     The following table identifies the directors and executive officer of the
Corporation and their ages and positions as of the date of this Prospectus.
Because the Corporation is organized as a special purpose entity and will be
largely passive, it is expected that the officers and directors in such
capacity will participate in the management of the Corporation only to a
limited extent.  Most of the actions related to maintaining and servicing the
assets will be performed by SLFC.

     Mr. Feinstein has been a Director of the Corporation since its formation
in May 1997.  Mr. Feinstein is also a Director of SLFC and has been a Director
of the Original Issuer since its formation in 1978.  He also is a Director of
EAC.  Mr. Feinstein has been self-employed as a business consultant in
Aberdeen, South Dakota since 1990.

     Mr. Jewett has been a Director of the Corporation since its formation in

South Dakota, which has sold a substantial number of Student Loans to the
Original Issuer in past years and is expected to continue selling Student
Loans to the Corporation in the future.

     Except for Mr. Sanderson, none of the directors and officers listed above
will be compensated directly by the Corporation nor with any funds or assets
of the Corporation.  Mr. Sanderson will be paid for serving as an executive
officer of the Corporation.  Mr. Sanderson's compensation will be based upon
the amount of time he spends handling the Corporation's affairs.  It is
currently estimated that he will receive approximately $35,000 per year for
his service as an executive officer of the Corporation.

     It is anticipated that the independent directors of the Corporation to be
appointed as described above will receive compensation of approximately $2,500
per year.


                         THE SLFC SERVICING AGREEMENT

IN GENERAL

     The Corporation and the Trustee will enter into a Servicing Agreement,
dated as of February 1, 1998 (the "SLFC Servicing Agreement"), with SLFC.  A
form of the SLFC Servicing Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part.  The following
summary describes certain provisions of the SLFC Servicing Agreement.  The
summary does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all of the provisions of the SLFC Servicing
Agreement.

     Pursuant to the SLFC Servicing Agreement, SLFC agrees to provide services
to the Corporation and the Trustee in connection with the origination and
acquisition of Student Loans to be Financed, to commence servicing the
Financed Student Loans as of the day they are Financed and to service the
Financed Student Loans, all in accordance with the SLFC Servicing Agreement.
SLFC may perform all or part of its origination, acquisition, and servicing
activities through a subcontractor.  SLFC is required to perform or cause its
subcontractor to perform all services under the SLFC Servicing Agreement in
compliance with the Higher Education Act, applicable requirements of the
Guarantee Agency and all other applicable federal, state and local laws and
regulations.  SLFC will be responsible for the performance of its obligations
under the SLFC Servicing Agreement, whether such obligations are performed by
SLFC or by its subcontractor, and SLFC will be responsible for any fees and
payments required by the subcontractor.  The SLFC Servicing Agreement requires
a subcontractor to be subject to the same obligations relating to audits,
examinations and inspections as to which SLFC is subject.  SLFC also agrees to
perform various duties of the Corporation under the Indenture.

ACQUISITION PROCESS

     Unless and until otherwise directed in writing by the Corporation, SLFC
agrees to provide to the Trustee all certificates and directions required to
be delivered by the Corporation to the Trustee under the Indenture in
connection with the Financing through acquisition of Eligible Loans and
Student Loans thereunder.  SLFC also agrees to work with the Lenders to obtain
from each Lender loan documentation and information relating to each Student
Loan to be Financed and to establish and maintain all records delivered to
SLFC with respect to each Financed Student Loan, and complete records of
SLFC's servicing of the Financed Student Loan from the date SLFC's servicing
commences.  However, SLFC will not conduct a complete file and note
examination of each Student Loan to be Financed.

ORIGINATION PROCESS

     Unless and until otherwise directed in writing by the Corporation, SLFC
agrees to provide to the Trustee all certificates and directions required to
be delivered by the Corporation to the Trustee under the Indenture in
connection with the Financing through origination of Eligible Loans and
Student Loans thereunder.  SLFC also

                                      -67-
<PAGE>
 
agrees to provide disbursement and origination services in connection with the
origination and disbursement of Eligible Loans under the Indenture.

SERVICING

     SLFC agrees to perform all servicing obligations relating to the Financed
Student Loans required of the Corporation or the Trustee, or which the
Corporation or the Trustee is required to cause the Servicer to perform.  The
SLFC Servicing Agreement specifies various activities and obligations to be
performed by SLFC in servicing the Financed Student Loans.  These activities
and obligations include, without limitation, file maintenance; maintaining
Guarantee coverage on Financed Student Loans; handling borrower requests for
forbearance and deferments; exercising due diligence (within the meaning of
the Higher Education Act and the Guarantee Program regulations) in the
servicing, administration and collection of all Financed Student Loans;
collecting payments of principal and interest, Special Allowance Payments, and
Guarantee Payments with respect to Financed Student Loans and causing all such
interest subsidy payments and Special Allowance Payments to be forwarded by
the Secretary of Education directly to the Trustee for immediate deposit into
the appropriate fund or account under the Indenture and depositing all other
such payments immediately upon receipt into a lock-box account (which shall be
part of the Revenue Fund) to be established by the Trustee in the name of and
for the account of the Trustee; representing the interests of the Corporation
and the Trustee in handling discrepancies or disputes, if any, with the
Secretary of Education; preparing and maintaining all appropriate accounting
records with respect to all transactions related to each Financed Student
Loan; for defaulted Financed Student Loans, taking steps necessary to file and
prove a claim for loss with the Secretary of Education or the Guarantee
Agency, as the case may be and as required, and assuming responsibility for
all necessary communications and contacts with the Secretary of Education or
the Guarantee Agency, as the case may be and as required, to recover on such
defaulted Financed Student Loans within the time required by the Higher
Education Act and the requirements of the Guarantee Agency; if a claim is
denied by the Secretary of Education or the Guarantee Agency, as the case may
be, under circumstances resulting in a Lender being required by a Student Loan
Purchase Agreement to repurchase a Financed Student Loan, taking such action
as shall be necessary to allow the Corporation or the Trustee to cause such
Lender to repurchase such Financed Student Loan or to substitute a different
Eligible Loan in accordance with the requirements of the applicable Student
Loan Purchase Agreement; preparing and filing various reports with the
Secretary of Education, the Guarantee Agency, the Corporation and the Trustee;
identifying on the servicing system the Notes as the source of financing for
each such Financed Student Loan; and maintaining duplicates or copies of
certain file documents.

RIGHT OF INSPECTION AND AUDITS

     The SLFC Servicing Agreement provides that, subject to any restrictions
of applicable law, the Corporation, the Trustee, the Guarantee Agency, the
Secretary of Education and/or any governmental agency having jurisdiction over
the Corporation or the Trustee (and, in each case, such entities'
representatives), will have the right, at any time and from time to time,
during normal business hours, and upon reasonable notice to SLFC, to examine
and audit any and all of the SLFC's records or accounts pertaining to any
Financed Student Loan.  The Corporation and the Trustee also may  require SLFC
to furnish such documents as they from time to time deem necessary to
determine that SLFC has complied with the provisions of the SLFC Servicing
Agreement, the Student Loan Purchase Agreements and the Indenture.

     SLFC also agrees to have prepared and submitted to the Secretary of
Education and the Guarantee Agencies any third-party servicer compliance
audits and audited financial statements required under the Higher Education
Act and the Guarantee Program regulations relating to SLFC and its servicing
of Financed Student Loans, and any lender compliance audits required under the
Higher Education Act and the Guarantee Program regulations relating to the
Trustee (as the holder of the Financed Student Loans) and the Financed Student
Loans.  SLFC agrees to provide to the Corporation and the Trustee these and
various other specified reports and audits.

ADMINISTRATION AND MANAGEMENT

     SLFC agrees to perform various administrative activities and obligations
on behalf of the Corporation under the SLFC Servicing Agreement. These include
providing all necessary personnel, facilities, equipment, forms and supplies
for operating the Program in accordance with the Indenture; disseminating
information on the Program to Lenders and to student financial aid officers
and to other persons as necessary; controlling and accounting for the receipt
and expenditure of the Corporation's funds in accordance with the resolutions
of the Corporation's board of directors and the Indenture and maintaining
accurate and complete records on all aspects of the Program; reviewing all
statements and reports to the Corporation required of the Trustee, the
Servicer and the Lender in accordance with the provisions of the Indenture,
the SLFC Servicing Agreement and the Student Loan Purchase Agreements;
preparing and submitting to the Trustee the Monthly Servicing Reports required
to be delivered to the Noteholders pursuant to the Indenture; and determining
and notifying the Trustee and Auction Agent of the Net Loan Rate.  SLFC also
agrees to prepare for filing, and provide such other assistance as is required
by the Corporation to file, any other reports required to be filed by the
Corporation under the Indenture or under any applicable law, including without
limitation, the Higher Education Act and any federal and state securities
laws.

SERVICER AS BAILEE

     The SLFC Servicing Agreement provides that SLFC, in holding documents
relating to the Financed Student Loans, will hold such documents as bailee for
and on behalf of the Trustee.

PLAN FOR DOING BUSINESS

     In providing administrative services on behalf of the Corporation under
the SLFC Servicing Agreement, SLFC agrees to operate the Program in compliance
with the Plan for Doing Business of the Original Issuer, to advise the
Original Issuer if any amendments to the Plan for Doing Business are required
from time to time, and to assist the Original Issuer in preparing, obtaining
approval of, and filing any such amendments to the Plan for Doing Business.

SERVICING FEES

     The SLFC Servicing Agreement provides that SLFC shall be paid for the
performance of its functions under the SLFC Servicing Agreement (from funds
available for such purpose under the Indenture) a monthly fee in an amount
each month equal to 0.104167% of the outstanding principal balance of all
Financed Student Loans as of the last day of the immediately preceding month.
Such fee is required to be paid to SLFC on a monthly basis within fifteen (15)
days of receipt by the Trustee of a written monthly billing statement from
SLFC. If SLFC believes that it is necessary to increase the monthly fee
payable under the SLFC Servicing Agreement, it shall provide a written request
to the Corporation and the Trustee of its need for an increase in such fee,
together with all information required under the Indenture for the Trustee to
approve an increase in the fees payable thereunder.  SLFC acknowledges in the
SLFC Servicing Agreement that such fee shall not be increased unless the
conditions for increasing such fees under the Indenture have been satisfied.

     SLFC also acknowledges in the SLFC Servicing Agreement that the
Corporation and the Trustee contemplate paying all servicing fees payable
under the SLFC Servicing Agreement solely from funds available for such
purpose in the Administration Fund created under the Indenture, which funds
are primarily dependent upon collection by SLFC and receipt by the Trustee of
payments with respect to the Financed Student Loans.  SLFC agrees to continue
to be bound by the terms and provisions of the SLFC Servicing Agreement
relating to Financed Student Loans in all respects, and to perform for a
period of 120 days its obligations thereunder, regardless of the receipt or
non-receipt on a timely basis by it of any payments in respect of servicing
fees.

NO BANKRUPTCY OR INSOLVENCY PETITION

     SLFC agrees that it will not at any time institute against the
Corporation, or join in any institution against the Corporation of, any
bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings, or other proceedings under any federal or state bankruptcy or
similar law in connection with any obligation relating to the SLFC Servicing
Agreement.

BENEFIT OF THE NOTEHOLDERS

     The SLFC Servicing Agreement recites that it is made and entered into for
the benefit of all Noteholders, and its provisions may be enforced not only by
the parties thereto but also by the Noteholders in the manner and to the
extent to which Noteholders may enforce provisions of the Indenture.

AMENDMENT

     The SLFC Servicing Agreement may be amended, supplemented or modified
only by written instrument duly executed by all parties thereto and only upon
receipt of a written certificate from the Corporation and the Trustee that
such amendment, supplement or modification will not deprive any Noteholder in
any material respect of the security afforded by the SLFC Servicing Agreement.

TERM AND TERMINATION

     The term of the SLFC Servicing Agreement continues for so long as any of
the Notes remain Outstanding, unless the SLFC Servicing Agreement is
terminated in accordance with its terms. The SLFC Servicing Agreement shall
terminate:

     A.     If SLFC shall:

          1.     admit in writing its inability to pay its debts
                 generally as they become due;

          2.     consent to the appointment of a custodian (as that term
                 is defined in the federal Bankruptcy Code) for or
                 assignment to a custodian of the whole or any
                 substantial part of SLFC's property, or fail to stay,
                 set aside or vacate within sixty (60) days from the
                 date of entry thereof any order or decree entered by a
                 court of competent jurisdiction ordering such
                 appointment or assignment;

          3.     commence any proceeding or file a petition under the
                 provisions of the federal Bankruptcy Code for
                 liquidation, reorganization or adjustment of debts, or
                 under any insolvency law or other statute or law
                 providing for the modification or adjustment of the
                 rights of creditors, or fail to stay, set aside or
                 vacate within sixty (60) days from the date of entry
                 thereof any order or decree entered by a court of
                 competent jurisdiction pursuant to an involuntary
                 proceeding, whether under federal or state law,
                 providing for liquidation or reorganization of SLFC or
                 modification or adjustment of the rights of creditors;
                 or

          4.     contest in writing the validity or enforceability of
                 the SLFC Servicing Agreement as a whole or deny in
                 writing that the SLFC Servicing Agreement as a whole is
                 binding upon SLFC;

     B.     upon written notice by the Corporation or the Trustee to
            SLFC, if SLFC materially breaches its obligations, or any
            representation or warranty, under the SLFC Servicing
            Agreement; or

                                      -70-
<PAGE>
 
     C.     upon written notice by the Corporation or the Trustee, if at
            any time the Guarantee Agency or the Department of Education
            has issued a notice of suspension or termination against
            SLFC, or has suspended or terminated the payment of all
            claims with respect to Financed Student Loans or, in the
            case of the Department of Education, all Special Allowance
            Payments or interest benefit payments with respect to
            Financed Student Loans as a result of actions or omissions
            of SLFC (it being understood that the cessation of less than
            all such claims or payments may constitute a breach under
            clause (B) above).

Notwithstanding the foregoing, any termination pursuant to clauses (B) or (C)
will be subject to the following conditions.  If such breach under clause (B)
or suspension or termination under clause (C) is capable of being cured within
90 days without, in the judgment of the Trustee, adversely affecting the
security provided to the Noteholders by the Financed Student Loans and the
related Guarantee Payments, Special Allowance Payments and interest subsidy
payments, SLFC shall have the right to cure such breach, within 90 days of the
date SLFC learns of such breach or receives notice of such breach from the
Corporation or the Trustee, prior to such termination.  If such breach is not
capable of being cured in the manner specified above, no termination pursuant
to clause (B) or (C) shall occur if, in the judgment of the Trustee, such
breach or suspension or termination will not adversely affect the security
provided the Noteholders by the Financed Student Loans and the related
Guarantee Payments, Special Allowance Payments and interest subsidy payments.

     SLFC agrees to promptly notify the Trustee and the Corporation of any
occurrence or condition which constitutes (or which with the passage of time
or the giving of notice or both would constitute) an event permitting the
termination of the SLFC Servicing Agreement.  SLFC also agrees to continue
performing its obligations under the Servicing Agreement until a successor
Servicer has been appointed.


                DESCRIPTION OF FINANCED ELIGIBLE LOAN PROGRAM

BACKGROUND OF ORIGINAL ISSUER'S PROGRAM

     The Original Issuer was organized as a secondary market for student loans
for lenders throughout the State of South Dakota, including banks, savings and
loan associations and credit unions.  The Original Issuer began operating a
secondary market program in 1979 and financed its initial acquisitions of
student loans through the issuance of its student loan revenue bonds.  The
Original Issuer has ongoing contact with, and holds numerous workshop meetings
in various locations in the State and surrounding States which are attended
by, approximately 250 financial and educational institutions.  SLFC will
undertake similar activities to make the financial and education communities
aware of its activities and objectives.

     The following table lists the approximate aggregate outstanding principal
balances of all Student Loans acquired by the Original Issuer from the
proceeds of its tax exempt student loan revenue bond issues during each of the
last six fiscal years and during the six months ended December 31, 1997.
These Student Loans have been made to Eligible Borrowers for the
post-secondary education of (a) residents of the State attending
post-secondary schools located within or without the State, or (b) residents
of a state other than the State attending post-secondary schools located
within the State (sometimes referred to herein as "In-State Loans").  The Code
requires that proceeds of tax exempt debt obligations issued by the Original
Issuer generally be used only to acquire In-State Loans.

</TABLE>

     In addition to the loans included in the table above, the Original Issuer
has acquired Student Loans from the proceeds of its taxable borrowings during
each year since 1988.  In general, the Original Issuer has used the proceeds
of these financings to acquire Student Loans for which the borrower is neither
a resident of the State nor attending an eligible school located within the
State.  The following table lists the approximate aggregate outstanding
principal balances of all Student Loans acquired by or on behalf of the
Original Issuer from the proceeds of its taxable borrowings for each of the
last six fiscal years and for the six months ended December 31, 1997.

</TABLE>


DESCRIPTION OF ELIGIBLE LOANS TO BE FINANCED

     It is expected that a portion of the proceeds of the Series 1998-1 Notes
deposited in the Acquisition Fund will be used to refinance the Original
Issuer's portfolio of approximately $586,630,000 aggregate principal amount of
student loans.  Certain characteristics of such portfolio as of December 31,
1997 are set forth below under "Characteristics of the Initial Financed
Eligible Loans."  Based on outstanding principal amounts as of December 31,
1997, approximately 47% of such Financed Eligible Loans have been acquired by
the Original Issuer from two Lenders (and affiliates thereof).

     It is expected that the remaining proceeds of the Series 1998-1 Notes
deposited in (i) the Series 1998-1 Tax Exempt Acquisition Account will be used
to acquire or originate approximately $241,070,000 additional aggregate
principal amount of Eligible Loans that are In-State Loans on or before April
15, 2002 and (ii) the Series 1998-1 Taxable Acquisition Account will be used
to acquire or originate approximately $64,110,000 additional aggregate
principal amount of Eligible Loans that are not In-State Loans on or before
February 1, 1999.  See "Application of Series 1998-1 Note Proceeds."

     Although the Higher Education Act contains certain provisions that may
decrease the principal amount of Eligible Loans made by Lenders, the
Corporation does not expect that such provisions will affect its ability to
spend the proceeds of the Series 1998-1 Notes initially deposited in the
Acquisition Fund to acquire Eligible Loans.  There is no assurance, however,
that relevant federal laws, including the Higher Education Act, will not be
amended in

                                      -72-
<PAGE>
 
a manner that may adversely affect the qualification of Student Loans as
Eligible Loans under the Indenture and thus prevent their acquisition by the
Trustee or that may decrease the aggregate principal amount of Eligible Loans
made by Lenders and available for purchase by the Trustee.  Proposals by
Congress and the Administration to amend the Higher Education Act could affect
the qualification of Student Loans made under the Federal Family Education
Loan Program as Eligible Loans.  If any such amendments are enacted, the
Corporation may seek any necessary Rating Agency approvals to allow it to
finance such Student Loans under the Indenture.  If the Trustee does not
acquire all the Eligible Loans which it is expected to acquire, the
Corporation may use the unexpended portion of the Series 1998-1 Notes proceeds
and Balances in the Series 1998-1 Tax Exempt and Taxable Surplus Sub-Accounts
to redeem Series 1998-1 Notes which are called for redemption.  See
"Description of Series 1998-1 Notes -- Special Call for Redemption -- From
Unused Proceeds".

     The First Supplemental Indenture contains various limits on certain types
of Eligible Loans that may be Financed (originated or purchased) after the
Date of Issuance, with proceeds deposited in the Series 1998-1 Tax Exempt
Acquisition Account and the Series 1998-1 Taxable Acquisition Account without
receiving further approval from the Rating Agencies.  The First Supplemental
Indenture limits the amount of additional Consolidation Loans that may be
Financed after the Date of Issuance from (i) the Series 1998-1 Tax Exempt
Acquisition Account (together with the Series 1998-1 Tax Exempt Surplus
Sub-Account) to the greater of (a) $49,000,000, or (b) 20% of the aggregate of
the amounts applied from such Accounts, after the Date of Issuance, to the
acquisition or origination of all Student Loans; and (ii) the Series 1998-1
Taxable Acquisition Account (together with the Series 1998-1 Taxable Surplus
Sub-Account) to the greater of (a) $26,000,000, or (b) 40% of the aggregate of
the amounts applied from such Accounts, after the Date of Issuance, to the
acquisition or origination of all Student Loans.  The First Supplemental
Indenture also limits the aggregate amount of Eligible Loans for which the
first disbursement is made on or after July 1, 1998, other than Consolidation
Loans, that may be Financed after the Date of Issuance from the Series 1998-1
Tax Exempt Acquisition Account, the Series 1998-1 Tax Exempt Surplus
Sub-Account, the Series 1998-1 Taxable Acquisition Account and the Series
1998-1 Taxable Surplus Sub-Account to $5,000,000.  Additionally, the First
Supplemental Indenture limits the aggregate amount of Financed Eligible Loans
that may be subject to certain forms of interest rate reduction features to
Borrowers.  In all these cases, the Corporation could use Balances in such
Accounts or Sub-Accounts to originate or acquire additional amounts of such
Eligible Loans if it delivers to the Trustee a Corporation certificate
certifying that, based on a Cash Flow Projection, the Financing of such
Eligible Loans will not materially adversely affect the Corporation's ability
to pay Debt Service on the Outstanding Notes and on Outstanding Other
Indenture Obligations, to pay Carry-Over Amounts (including accrued interest
thereon) with respect to Outstanding Notes or to make required deposits to the
Rebate Fund.  The Corporation does not expect that these limitations will
prevent the expenditure of the proceeds of the Series 1998-1 Note proceeds
deposited in the Acquisition Fund.

     For a more detailed description of student loans under the Higher
Education Act, see "Description of Federal Family Education Loan Program".
For a description of the Guarantee Agencies, see "Description of the Guarantee
Agencies".

     The Indenture also permits the Financing of Student Loans from moneys in
the Surplus Account under certain circumstances.  Such Student Loans are not
required to be Eligible Loans.  See "Summary of the Indenture -- Funds and
Accounts -- Surplus Fund".

SUMMARY OF STUDENT LOAN PURCHASE AGREEMENTS

     The Original Issuer entered into Student Loan Purchase Agreements with
approximately 500 Lenders for the purchase of Eligible Loans to be refinanced
with the proceeds of the Series 1998-1 Notes (the "Original Issuer Student
Loan Purchase Agreements").  The Original Issuer's right, title and interest
in the Original Issuer Student Loan Purchase Agreements will be pledged to the
Trustee.  In addition, the Corporation has entered into Student Loan Purchase
Agreements with approximately 140 Lenders for the purchase of additional
Eligible Loans by the Trustee from the proceeds of the Series 1998-1 Notes and
expects to enter into additional Student Loan Purchase Agreements for the
purchase of additional Eligible Loans by the Trustee from Balances in the
Series 1998-1 Tax Exempt and Taxable Surplus Sub-Accounts (collectively, the
"Corporation Student Loan Purchase Agreements").

                                      -73-
<PAGE>
 
     As of December 31, 1997, approximately $99 million outstanding principal
amount of the Eligible Loans to be Financed on the Date of Issuance
represented Consolidation Loans originated by the Original Issuer (and not
acquired from Lenders pursuant to Original Issuer Student Loan Purchase
Agreements).  Consolidation Loans and other Eligible Loans Financed after the
Date of Issuance which are originated by the Trustee also will not be covered
by Corporation Student Loan Purchase Agreements.

     The Corporation Student Loan Purchase Agreements will provide for the
purchase by the Trustee on behalf of the Corporation, of Eligible Loans at
100% of their outstanding unpaid principal amount, plus accrued interest
thereon payable by the Borrower.  The Corporation Student Loan Purchase
Agreements require the Lender to report and offset against its interest
subsidy and Special Allowance Payments all authorized origination fees.  Under
certain circumstances, the Trustee will also pay to the Lender reasonable
transfer, origination or assignment fees and a premium to the extent permitted
by the Indenture.  See "Summary of the Indenture -- Funds and Accounts --
Acquisition Fund".

     Each Lender, with respect to each Financed Eligible Loan purchased under
a Student Loan Purchase Agreement, has represented or will represent that at
the date of sale by the Lender to the Original Issuer or the Trustee, each
Eligible Loan was or will be Guaranteed.  Each Lender makes additional
representations as to the validity, enforceability and transferability of each
such Eligible Loan and as to the legal authority of the Lender to engage in
the transactions contemplated by the respective Student Loan Purchase
Agreement.

     The Student Loan Purchase Agreements provide that if any representation
furnished by a Lender with respect to an Eligible Loan sold to the Original
Issuer or the Trustee proves to have been materially incorrect, or if the
Guarantee Agency refuses to honor all or part of a Guarantee claim filed with
respect to any Financed Eligible Loan on account of any circumstance or event
occurring prior to the sale of such Eligible Loan to the Original Issuer or
the Trustee, or under certain other circumstances specified in the Student
Loan Purchase Agreement, the Lender shall repurchase such loan at a price
equal to the then outstanding principal balance, plus accrued interest and
Special Allowance Payments, plus any expenses incurred by the Corporation, the
Original Issuer or the Trustee in connection therewith and any other amounts
paid to the Lender by the Original Issuer or the Trustee in connection with
the acquisition of such loan.

SERVICING AND "DUE DILIGENCE"

     The Servicer will service student loans originated or acquired by the
Trustee under the Indenture.  The Corporation will covenant in the Indenture
to cause a Servicer to administer and collect all Financed Student Loans in a
competent, diligent and orderly fashion, and in accordance with all
requirements of the Higher Education Act, the Secretary of Education, the
Indenture, the Federal Reimbursement Contracts and the Guarantee Agreements.

     The Higher Education Act requires that the Original Issuer, the Trustee
(in its capacity as "eligible lender"), a Lender and their agents (including
the Servicer) and employees exercise "due diligence" in the making, servicing
and collection of Financed Student Loans and that a Guarantee Agency exercise
due diligence in collecting loans which it holds.  The Higher Education Act
defines "due diligence" as requiring the holder of a Student Loan to utilize
servicing and collection practices at least as extensive and forceful as those
generally practiced by financial institutions for the collection of consumer
loans, and requires that certain specified collection actions be taken within
certain specified time periods with respect to a delinquent loan or defaulted
loan.  The Guarantee Agencies have established procedures and standards for
due diligence to be exercised by each Guarantee Agency and by Lenders
(including the Original Issuer and the Trustee) which hold loans that are
guaranteed by the respective Guarantee Agencies.  The Original Issuer, the
Trustee, a Lender, or a Guarantee Agency may not relieve itself of its
responsibility for meeting these standards by delegation to any servicing
agent.  Accordingly, if the Original Issuer has failed to meet such standards,
or if a Lender or the Servicer fails to meet such standards, the Trustee's
ability to realize the benefits of Guarantee Payments, and (with respect to
Student Loans eligible for such payments) interest

                                      -74-
<PAGE>
 
subsidy payments and Special Allowance Payments may be adversely affected.  If
a Guarantee Agency fails to meet such standards, that Guarantee Agency's
ability to realize the benefits of federal reinsurance payments may be
adversely affected.


                        CHARACTERISTICS OF THE INITIAL
                           FINANCED ELIGIBLE LOANS

     This section sets forth tables describing certain characteristics, as of
December 31, 1997, of the Eligible Loans expected to be Financed on the Date
of Issuance of the Series 1998-1 Notes.  The Corporation expects that the
Eligible Loans to be Financed on the Date of Issuance will also include
approximately $8.2 million principal amount of Eligible Loans originated or
purchased by or on behalf of the Original Issuer between December 31, 1997 and
the Date of Issuance, and that the characteristics of the Eligible Loans
reflected in such tables will vary due to the continued amortization of such
Eligible Loans between such date and the Date of Issuance.  Although the
statistical distribution of the characteristics of the Financed Eligible Loans
as of the Date of Issuance will vary somewhat from the statistical
distribution of such characteristics shown below, the Corporation does not
believe that such characteristics will differ materially.

             DESCRIPTION OF FEDERAL FAMILY EDUCATION LOAN PROGRAM

GENERAL

    The Higher Education Act sets forth provisions establishing the Federal
Family Education Loan Program, pursuant to which state agencies or private
nonprofit corporations administering student loan insurance programs (referred
to as "guarantee agencies") are reimbursed for losses sustained in the
operation of their programs, and holders of certain loans made under such
programs are paid subsidies for owning such loans.

    The Higher Education Act currently authorizes certain student loans to be
covered under the Federal Family Education Loan Program if they are contracted
for and paid to the student prior to September 30, 2002, unless a student has
received a loan under the Federal Family Education Loan Program prior to such
date, in which case that student may receive a student loan covered by the
Federal Family Education Loan Program until September 30, 2006.  Congress has
extended similar authorization dates in prior versions of the Higher Education
Act; however,

                                      -80-
<PAGE>
 
there can be no assurance that the current authorization dates will again be
extended or that the other provisions of the Higher Education Act will be
continued in their present form.

    Various amendments to the Higher Education Act have revised the Federal
Family Education Loan Program from time to time. These amendments include, but
are not limited to, the Balanced Budget Act of 1997 (the "1997 Amendments"),
the Higher Education Technical Amendments Act of 1993 (the "1993 Technical
Amendments"), the Omnibus Budget Reconciliation Act of 1993 (the "1993
Amendments"), the Higher Education Amendments of 1992 (the "1992 Amendments"),
which reauthorized the Federal Family Education Loan Program, the Omnibus
Budget Reconciliation Act of 1990, the Omnibus Budget Reconciliation Act of
1989 (the "1989 Amendments"), the Omnibus Budget Reconciliation Act of 1987,
the Higher Education Technical Amendments Act of 1987 (the "1987 Amendments"),
the Higher Education Amendments of 1986 (the "1986 Amendments"), which
reauthorized the Federal Family Education Loan Program, the Consolidated
Omnibus Budget Reconciliation Act of 1985, the Postsecondary Student
Assistance Amendments of 1981 (the "1981 Amendments") and the Education
Amendments of 1980 (the "1980 Amendments").

    The 1993 Amendments made several changes to the terms of the Federal
Family Education Loan Program that are adverse to the Guarantee Agencies and
lenders under the Federal Family Education Loan Program.  In addition, the
1993 Amendments authorized a program of student loans originated by schools on
behalf of the Secretary of Education to partially replace the Federal Family
Education Loan Program.  See "Direct Loans" below.  There can be no assurance
that relevant federal laws, including the Higher Education Act, will not be
further changed in a manner that may adversely impact the receipt of funds by
the Guarantee Agencies or by the Corporation or the Trustee with respect to
Financed Eligible Loans or the amount of loans made by Lenders and available
for purchase by the Trustee on behalf of the Corporation.

     Proposals have been made by Congress and the Administration which, if
enacted into law, would amend the Higher Education Act and make various
changes to the Federal Family Education Loan Program, including changes that
would reduce various payments to Guarantee Agencies and restructure guarantee
agencies' operations and programs and revise terms of student loans and
payments to Lenders.  There is no certainty that any of the proposals will be
enacted into law in their current form or at all, and the Corporation cannot
predict at this time how such legislation, if enacted, would affect SLFC's
business or operations, or the Corporation.

     This is only a summary of certain provisions of the Higher Education
Act.  Reference is made to the text of the Higher Education Act for full and
complete statements of its provisions.

LOAN TERMS

  General

    Four types of loans are currently available under the Federal Family
Education Loan Program:  Stafford Loans, Unsubsidized Stafford Loans, Plus
Loans and Consolidation Loans.  These loan types vary as to eligibility
requirements, interest rates, repayment periods, loan limits and eligibility
for interest subsidies and Special Allowance Payments.  Some of these loan
types have had other names in the past.  References herein to the various loan
types include, where appropriate, predecessors to such loan types.

    The primary loan under the Federal Family Education Loan Program is the
Stafford Loan.  Students who are not eligible for Stafford Loans based on
their economic circumstances may be able to obtain Unsubsidized Stafford
Loans.  Parents of students may be able to obtain Plus Loans.  Consolidation
Loans are available to borrowers with existing loans made under the Federal
Family Education Loan Program and certain other federal programs to
consolidate repayment of such existing loans.  For periods of enrollment
beginning prior to July 1, 1994, SLS Loans were available to students with
costs of education that were not met by other sources and that exceeded the
Stafford or Unsubsidized Stafford Loan limits.

                                      -81-

  Eligibility

    General.  A student is eligible for loans made under the Federal Family
Education Loan Program only if he or she:  (i) has been accepted for
enrollment or is enrolled in good standing at an eligible institution of
higher education (which term includes certain vocational schools), (ii) is
carrying or planning to carry at least one-half the normal full-time workload
for the course of study the student is pursuing as determined by the
institution (which, in the case of a loan to cover the cost of a period of
enrollment beginning on or after July 1, 1987, must either lead to a recognized
educational credential or be necessary for enrollment in a course of study
that leads to such a credential), (iii) has agreed to notify promptly the
holder of the loan concerning any change of address, (iv) (if presently
enrolled) is maintaining satisfactory progress in the course of study he or
she is pursuing, (v) does not owe a refund on, and is not (except as
specifically permitted under the Higher Education Act) in default under, any
loan or grant made under the Higher Education Act, (vi) has filed with the
eligible institution a statement of educational purpose, (vii) meets certain
citizenship requirements, and (viii) (except in the case of a graduate or
professional student) has received a preliminary determination of eligibility
or ineligibility for a Pell Grant.

    Stafford Loans.  Stafford Loans generally are made only to student
borrowers who meet certain needs tests.  The educational institution must
provide the lender with a statement evidencing a determination of need for a
loan, and the amount of such need, calculated by subtracting from the
estimated cost of attendance the sum of the expected family contribution with
respect to the student plus the estimated financial assistance available to
such student.  The amounts of the expected family contribution, estimated
available financial assistance, and estimated costs of attendance are to be
computed in accordance with standards set forth in the Higher Education Act.

    Unsubsidized Stafford Loans.  A student borrower meeting the requirements
set forth under "General" above is eligible for an Unsubsidized Stafford Loan
without regard to need.  Unsubsidized Stafford Loans were not available before
October 1, 1992.

    Plus Loans.  Plus Loans are made only to borrowers who are parents (and,
under certain circumstances, spouses of remarried parents) of dependent
undergraduate students.  For Plus Loans made on or after July 1, 1993, the
parent borrower must not have an adverse credit history (as determined
pursuant to criteria established by the Department of Education).  Prior to
the 1986 Amendments, the Higher Education Act did not distinguish between Plus
Loans and SLS Loans.  Student borrowers were eligible for Plus Loans; however,
parents of graduate and professional students were ineligible.

    SLS Loans.  Eligible borrowers for SLS Loans were limited to (a) graduate
or professional students, (b) independent undergraduate students, and (c)
under certain circumstances, dependent undergraduate students, if such
students' parents were unable to obtain a Plus Loan and were also unable to
provide such students' expected family contribution. Prior to the 1987
Amendments, a dependent undergraduate student was not eligible under any
circumstances.  Except as described in clause (c), eligibility was determined
without regard to need.

    Consolidation Loans.  To be eligible for a Consolidation Loan a borrower
must (a) have outstanding indebtedness on student loans made under the Federal
Family Education Loan Program and/or certain other federal student loan
programs, and (b) be in repayment status or in a Grace Period, or be a
defaulted borrower who has made arrangements to repay the defaulted loan(s)
satisfactory to the holder of the defaulted loan(s).  A married couple who
agree to be jointly liable on a Consolidation Loan for which the application
is received on or after January 1, 1993 may be treated as an individual for
purposes of obtaining a Consolidation Loan.  For Consolidation Loans disbursed
prior to July 1, 1994 the Borrower was required to have outstanding student
loan indebtedness of at least $7,500.  Prior to the adoption of the 1993
Technical Amendments, Plus Loans could not be included in the Consolidation
Loan.  For Consolidation Loans for which the applications were received prior
to January 1, 1993, the minimum student loan indebtedness was $5,000 and the
borrower could not be delinquent more than 90 days in the payment of such
indebtedness.

                                      -82-

  Interest Rates

    The Higher Education Act establishes maximum interest rates for each of
the various types of loans.  These rates vary not only among loan types, but
also within loan types depending upon when the loan was made or when the
borrower first obtained a loan under the Federal Family Education Loan
Program.  The Higher Education Act allows lesser rates of interest to be
charged.  Many Lenders have offered repayment incentives or other programs
that involve reduced interest rates on certain loans made under the Federal
Family Education Loan Program.

    Stafford Loans.  For a Stafford Loan made prior to July 1, 1994, the
applicable interest rate for a borrower who, on the date the promissory note
was signed, did not have an outstanding balance on a previous loan which was
made, insured or guaranteed under the Federal Family Education Loan Program (a
"New Borrower"):

    (a)  is 7% per annum for a loan covering a period of instruction beginning
         before January 1, 1981;

    (b)  is 9% per annum for a loan covering a period of instruction beginning
         on or after January 1, 1981, but before September 13, 1983;

    (c)  is 8% per annum for a loan covering a period of instruction beginning
         on or after September 13, 1983, but before July 1, 1988;

    (d)  for a loan made prior to October 1, 1992, covering a period of
         instruction beginning on or after July 1, 1988, is 8% per annum for
         the period from the disbursement of the loan to the date which is
         four years after the loan enters repayment, and thereafter shall be
         adjusted annually, and for any 12-month period commencing on a July 1
         shall be equal to the bond equivalent rate of 91-day U.S. Treasury
         bills auctioned at the final auction prior to the preceding June 1,
         plus 3.25% per annum (but not to exceed 10% per annum); or

    (e)  for a loan made on or after October 1, 1992 shall be adjusted
         annually, and for any 12-month period commencing on a July 1 shall be
         equal to the bond equivalent rate of 91-day U.S. Treasury bills
         auctioned at the final auction prior to the preceding June 1, plus
         3.1% per annum (but not to exceed 9% per annum).

For a Stafford Loan made prior to July 1, 1994, the applicable interest rate
for a borrower who, on the date the promissory note evidencing the loan was
signed, had an outstanding balance on a previous loan made, insured or
guaranteed under the Federal Family Education Loan Program (a "Repeat
Borrower"):

    (f)  for a loan made prior to July 23, 1992 is the applicable interest
         rate on the previous loan or, if such previous loan is not a Stafford
         Loan, 8% per annum; or

    (g)  for a loan made on or after July 23, 1992 shall be adjusted annually,
         and for any twelve month period commencing on a July 1 shall be equal
         to the bond equivalent rate of 91-day U.S. Treasury bills auctioned
         at the final auction prior to the preceding June 1, plus 3.1% per
         annum but not to exceed:

         (i)     7% per annum in the case of a Stafford Loan made to a
                 borrower who has a loan described in clause (a) above;

         (ii)    8% per annum in the case of (A) a Stafford Loan made to a
                 borrower who has a loan described in clause (c) above, (B) a
                 Stafford Loan which has not been in repayment for four years
                 and which was made

                                      -83-
<PAGE>
 
                 to a borrower who has a loan described in clause (d) above or
                 (C) a Stafford Loan for which the first disbursement was made
                 prior to December 20, 1993 to a borrower whose previous loans
                 do not include a Stafford Loan or an Unsubsidized Stafford
                 Loan;

         (iii)   9% per annum in the case of a (A) Stafford Loan made to a
                 borrower who has a loan described in clauses (b) or (e) above
                 or (B) a Stafford Loan for which the first disbursement was
                 made on or after December 20, 1993 to a borrower whose
                 previous loans do not include a Stafford Loan or an
                 Unsubsidized Stafford Loan; and

         (iv)    10% per annum in the case of a Stafford Loan which has been
                 in repayment for four years or more and which was made to a
                 borrower who has a loan described in clause (d) above.

    The interest rate on all Stafford Loans made on or after July 1, 1994,
regardless of whether the borrower is a New Borrower or a Repeat Borrower, is
the rate described in clause (g) above, except that such rate shall not exceed
8.25% per annum.  For any Stafford Loan made on or after July 1, 1995, the
interest rate is further reduced prior to the time the loan enters repayment
and during any Deferment Periods (as such term is defined below under
"Repayment").  During such periods, the formula described in clause (g) above
is applied, except that 2.5% is substituted for 3.1%, and the rate shall not
exceed 8.25% per annum.

    For loans made on or after July 1, 1998, the applicable rate will
continue to be adjusted annually, but for any 12-month period commencing on a
July 1 will be equal to the bond equivalent rate of securities with a
comparable maturity (as established by the Secretary of Education), plus 1%
per annum, but not to exceed 8.25% per annum.  There can be no assurance that
the interest rate provisions for such loans will not be further amended,
either before or after the rate described herein becomes effective.

    Unsubsidized Stafford Loans.  Unsubsidized Stafford Loans are subject to
the same interest rate provisions as Stafford Loans.

    Plus Loans.   The applicable interest rate on a Plus Loan:

    (a)  made on or after January 1, 1981, but before October 1, 1981 is 9%
         per annum;

    (b)  made on or after October 1, 1981, but before November 1, 1982 is 14%
         per annum;

    (c)  made on or after November 1, 1982, but before July 1, 1987 is 12% per
         annum;

    (d)  made on or after July 1, 1987 and before October 1, 1992 shall be
         adjusted annually, and for any 12-month period beginning on July 1
         shall be equal to the bond equivalent rate of 52-week U.S. Treasury
         bills auctioned at the final auction prior to the preceding June 1,
         plus 3.25% per annum (but not to exceed 12% per annum); or

    (e)  made on or after October 1, 1992 shall be adjusted annually, and for
         any 12-month period beginning on July 1 shall be equal to the bond
         equivalent rate of 52-week U.S. Treasury bills auctioned at the final
         auction prior to the preceding June 1, plus 3.1% per annum (but not
         to exceed 10% per annum).

    The applicable interest rate for Plus Loans made on or after July 1, 1994
is the same as that described in clause (e) above, except that such rate shall
not exceed 9% per annum.  For Plus Loans made on or after July 1, 1998, the
applicable rate will continue to be adjusted annually, but for any 12-month
period commencing on a July

                                      -84-
<PAGE>
 
1 will be equal to the bond equivalent rate of securities with a comparable
maturity (as established by the Secretary of Education), plus 2.1% per annum,
but not to exceed 9% per annum.

    If requested by the borrower, an eligible lender may consolidate SLS or
Plus Loans of the same borrower held by the lender under a single repayment
schedule. The repayment period for each included loan shall be based on the
commencement of repayment of the most recent loan. The consolidated loan shall
bear interest at a rate equal to the weighted average of the rates of the
included loans. Such a consolidation shall not be treated as the making of a
new loan.  In addition, at the request of the borrower, a lender may refinance
an existing fixed rate SLS or Plus Loan (including an SLS or Plus Loan held by
a different lender who has refused so to refinance such loan) at a variable
interest rate. In such a case, proceeds of the new loan are used to discharge
the original loan.

    SLS Loans.  The applicable interest rates on SLS Loans made prior to
October 1, 1992 are identical to the applicable interest rates on Plus Loans
made at the same time.  For SLS Loans made on or after October 1, 1992, the
applicable interest rate is the same as the applicable interest rate on Plus
Loans, except that the ceiling is 11% per annum instead of 10% per annum.

    Consolidation Loans.  A Consolidation Loan made prior to July 1, 1994
bears interest at a rate equal to the weighted average of the interest rates
on the loans retired, rounded to the nearest whole percent, but not less than
9% per annum.  Except as described in the next sentence, a Consolidation Loan
made on or after July 1, 1994 bears interest at a rate equal to the weighted
average of the interest rates on the loans retired, rounded upward to the
nearest whole percent, but with no minimum rate.  For a Consolidation Loan for
which the application is received by an eligible lender on or after November
13, 1997 and before October 1, 1998, the interest rate shall be adjusted
annually, and for any twelve month period commencing on a July 1 shall be
equal to the bond equivalent rate of 91-day U.S. Treasury bills auctioned at
the final auction prior to the preceding June 1, plus 3.1% per annum, but not
to exceed 8.25% per annum.  Notwithstanding these general interest rates, the
portion, if any, of a Consolidation Loan that repaid a loan made under the
federal health education assistance loan program may have a different interest
rate.  For a discussion of required payments that reduce the return on
Consolidation Loans, see "Fees -- Rebate Fees on Consolidation Loans" below.

  Loan Limits

    Each type of loan (other than Consolidation Loans, which are limited only
by the amount of eligible loans to be consolidated) is subject to limits as to
the maximum principal amount, both with respect to a given year and in the
aggregate.  All of the loans are limited to the difference between the cost of
attendance and the other aid available to the student.  Stafford Loans are
also subject to limits based upon the needs analysis as described above under
"Eligibility -- Stafford Loans" above.  Additional limits are described below.

    Stafford and Unsubsidized Stafford Loans.  Except as described in the next
paragraph, Stafford and Unsubsidized Stafford Loans are generally treated as
one loan type for loan limit purposes.  A student who has not successfully
completed the first year of a program of undergraduate education may borrow up
to $2,625 in an academic year.  A student who has successfully completed such
first year, but who has not successfully completed the second year may borrow
up to $3,500 per academic year.  An undergraduate student who has successfully
completed the first and second year, but who has not successfully completed
the remainder of a program of undergraduate education, may borrow up to $5,500
per academic year. For students enrolled in programs of less than an academic
year in length, the limits are generally reduced in proportion to the amount
by which such programs are less than one year in length.  A graduate or
professional student may borrow up to $8,500 in an academic year.  The maximum
aggregate amount of Stafford and Unsubsidized Stafford Loans (including that
portion of a Consolidation Loan used to repay such loans) which an
undergraduate student may have outstanding is $23,000.  The maximum aggregate
amount for a graduate and professional student, including loans for
undergraduate education, is $65,500.  The Secretary is authorized to increase
the limits applicable to graduate and professional students who are pursuing
programs which the Secretary determines to be exceptionally expensive.

                                      -85-
<PAGE>
 
    Under the 1993 Amendments, at the same time that SLS Loans were
eliminated, the loan limits for Unsubsidized Stafford Loans to independent
students, or dependent students whose parents cannot borrow a Plus Loan, were
increased by amounts equal to the prior SLS Loan limits (as described below
under "SLS Loans").

    Prior to the enactment of the 1992 Amendments, an undergraduate student
who had not successfully completed the first and second year of a program of
undergraduate education could borrow Stafford Loans in amounts up to $2,625 in
an academic year.  An undergraduate student who had successfully completed
such first and second year, but who had not successfully completed the
remainder of a  program of undergraduate education could borrow up to $4,000
per academic year.  The maximum for graduate and professional students was
$7,500 per academic year.  The maximum aggregate amount of Stafford Loans
which a borrower could have outstanding (including that portion of a
Consolidation Loan used to repay such loans) was $17,250. The maximum
aggregate amount for a graduate or professional student, including loans for
undergraduate education, was $54,750.  Prior to the enactment of the 1986
Amendments, the annual limits were generally lower.

    Plus Loans.  For Plus Loans made on or after July 1, 1993, the amounts of
Plus Loans are limited only by the student's unmet need.  Prior to that time
Plus Loans were subject to limits similar to those to which SLS Loans were
then subject (see "SLS Loans" below), applied with respect to each student on
behalf of whom the parent borrowed.

    SLS Loans.  A student who had not successfully completed the first and
second year of a program of undergraduate education could borrow an SLS Loan
in an amount of up to $4,000.  A student who had successfully completed such
first and second year, but who had not successfully completed the remainder of
a program of undergraduate education could borrow up to $5,000 per year.
Graduate and professional students could borrow up to $10,000 per year.  SLS
Loans were subject to an aggregate maximum of $23,000 ($73,000 for graduate
and professional students).  Prior to the 1992 Amendments, SLS Loans were
available in amounts of $4,000 per academic year, up to a $20,000 aggregate
maximum. Prior to the 1986 Amendments, a graduate or professional student
could borrow $3,000 of SLS Loans per academic year, up to a $15,000 maximum,
and an independent undergraduate student could borrow $2,500 of SLS Loans per
academic year minus the amount of all other Federal Family Education Loan
Program loans to such student for such academic year, up to a maximum amount
of all Federal Family Education Loan Program loans to that student of $12,500.
The 1989 Amendments limited the amount of SLS Loans for students enrolled in
programs of less than an academic year in length (similar to the limits
described above under "Stafford Loans"), and such limits were continued by the
1992 Amendments.

  Repayment

    Loans made under the Federal Family Education Loan Program (other than
Consolidation Loans) must provide for repayment of principal in periodic
installments over a period of not less than five nor more than ten years.  A
Consolidation Loan must be repaid during a period agreed to by the borrower
and lender, subject to maximum repayment periods which vary depending upon the
principal amount of the borrower's outstanding student loans (but no longer
than 30 years).  For Consolidation Loans for which the application was
received prior to January 1, 1993, the repayment period could not exceed 25
years.  The repayment period commences (a) not more than twelve months after
the borrower ceases to pursue at least a half-time course of study with
respect to Stafford Loans for which the applicable rate of interest is 7% per
annum, (b) not more than six months after the borrower ceases to pursue at
least a half-time course of study with respect to other Stafford Loans and
Unsubsidized Stafford Loans (the six month or twelve month periods are the
"Grace Periods") and (c) on the date of final disbursement of the loan in the
case of SLS, Plus and Consolidation Loans, except that the borrower of an SLS
Loan who also has a Stafford or Unsubsidized Stafford Loan may defer repayment
of the SLS Loan to coincide with the commencement of repayment of the Stafford
or Unsubsidized Stafford Loan.  During periods in which repayment of principal
is required, payments of principal and interest must in general be made at a
rate of not less than the greater of $600 per year or the interest that
accrues during the year, except that a borrower and lender may agree at any
time before or during the repayment period that repayment may be at a lesser
rate.  A borrower may agree, with concurrence of the lender, to repay the loan
in less than five years with the right subsequently to extend his

                                      -86-
<PAGE>
 
minimum repayment period to five years. Borrowers are entitled to accelerate,
without penalty, the repayment of all or any part of the loan.

    In addition, the 1992 Amendments required lenders of Consolidation Loans
to establish graduated or income-sensitive repayment schedules and required
lenders of Stafford and SLS Loans to offer borrowers the option of repaying in
accordance with graduated or income-sensitive repayment schedules.  The
Original Issuer has implemented (and SLFC will implement) graduated repayment
schedules and income-sensitive repayment schedules.  Use of income-sensitive
repayment schedules may extend the ten-year maximum term for up to five years.
In addition, if the repayment schedule on a loan that has been converted to a
variable interest rate does not provide for adjustments to the amount of the
monthly installment payments, the ten-year maximum term may be extended for up
to three years.

    No principal repayments need be made during certain periods of deferment
prescribed by the Higher Education Act ("Deferment Periods").  For loans to a
borrower who first obtained a loan which was disbursed before July 1, 1993,
deferments are available (i) during a period not exceeding three years while
the borrower is a member of the Armed Forces, an officer in the Commissioned
Corps of the Public Health Service or, with respect to a borrower who first
obtained a student loan disbursed on or after July 1, 1987, or a student loan
to cover the cost of instruction for a period of enrollment beginning on or
after July 1, 1987, an active duty member of the National Oceanic and
Atmospheric Administration Corps, (ii) during a period not in excess of three
years while the borrower is a volunteer under the Peace Corps Act, (iii)
during a period not in excess of three years while the borrower is a full-time
volunteer under the Domestic Volunteer Act of 1973, (iv) during a period not
exceeding three years while the borrower is in service, comparable to the
service referred to in clauses (ii) and (iii), as a full-time volunteer for an
organization which is exempt from taxation under Section 501(c)(3) of the
Code, (v) during a period not exceeding two years while the borrower is
serving an internship, the successful completion of which is required to
receive professional recognition required to begin professional practice or
service, or a qualified internship or residency program, (vi) during a period
not exceeding three years while the borrower is temporarily totally disabled,
as established by sworn affidavit of a qualified physician, or while the
borrower is unable to secure employment by reason of the care required by a
dependent who is so disabled, (vii) during a period not to exceed twenty-four
months while the borrower is seeking and unable to find full-time employment,
(viii) during any period that the borrower is pursuing a full-time course of
study at an eligible institution (or, with respect to a borrower who first
obtained a student loan disbursed on or after July 1, 1987, or a student loan
to cover the cost of instruction for a period of enrollment beginning on or
after July 1, 1987, is pursuing at least a half-time course of study for which
the borrower has obtained a loan under the Federal Family Education Loan
Program), or is pursuing a course of study pursuant to a graduate fellowship
program or a rehabilitation training program for disabled individuals approved
by the Secretary of Education, (ix) during a period, not in excess of 6
months, while the borrower is on parental leave, and (x) only with respect to
a borrower who first obtained a student loan disbursed on or after July 1,
1987, or a student loan to cover the cost of instruction for a period of
enrollment beginning on or after July 1, 1987, (A) during a period not in
excess of three years while the borrower is a full-time teacher in a public or
nonprofit private elementary or secondary school in a "teacher shortage area"
(as prescribed by the Secretary of Education), and (B) during a period not in
excess of 12 months for mothers, with preschool age children, who are entering
or re-entering the work force and who are compensated at a rate not exceeding
$1 per hour in excess of the federal minimum wage.  For loans to a borrower
who first obtains a loan on or after July 1, 1993, deferments are available
(a) during any period that the borrower is pursuing at least a half-time
course of study at an eligible institution or a course of study pursuant to a
graduate fellowship program or rehabilitation training program approved by the
Secretary, (b) during a period not exceeding three years while the borrower is
seeking and unable to find full-time employment, and (c) during a period not
in excess of three years for any reason which the lender determines, in
accordance with regulations under the Higher Education Act, has caused or will
cause the borrower economic hardship.  Economic hardship includes working full
time and earning an amount not in excess of the greater of the minimum wage or
the poverty line for a family of two.  Additional categories of economic hardshi
p are based on the relationship between a borrower's educational debt burden
and his or her income.  Prior to the 1992 Amendments, only the Deferment
Periods described above in clauses (vi) and (vii) (with respect to the parent
borrower) and the Deferment Period described in clause (viii) (with respect to
the parent borrower or a student on

                                      -87-
<PAGE>
 
whose behalf the parent borrowed) were available to Plus Loan borrowers, and
only the Deferment Periods described above in clauses (vi), (vii) and (viii)
were available to Consolidation Loan borrowers.  Prior to the 1986 Amendments,
Plus Loan borrowers were not entitled to Deferment Periods.  Deferment Periods
extend the ten year maximum term.

    The Higher Education Act also provides for periods of forbearance during
which the borrower, in case of temporary financial hardship, may defer any
payments.  A borrower is entitled to forbearance for a period not to exceed
three years while the borrower's debt burden under Title IV of the Higher
Education Act (which includes the Federal Family Education Loan Program)
equals or exceeds 20% of the borrower's gross income, and also is entitled to
forbearance while he or she is serving in a qualifying medical or dental
internship program or in a "national service position" under the National and
Community Service Trust Act of 1993.  In addition, mandatory administrative
forbearances are provided when exceptional circumstances such as a local or
national emergency or military mobilization exist; or when the geographical
area in which the borrower or endorser resides has been designated a disaster
area by the President of the United States or Mexico, the Prime Minister of
Canada, or by the governor of a state.  In other circumstances, forbearance is
at the lender's option.  Such forbearance also extends the ten year maximum
term.

    As described under "Contracts with Guarantee Agencies -- Federal Interest
Subsidy Payments" below, the Secretary of Education makes interest payments on
behalf of the borrower of certain eligible loans while the borrower is in
school and during Grace and Deferment Periods.  Interest that accrues during
periods of forbearance and, if the loan is not eligible for interest subsidy
payments, while the borrower is in school and during the Grace and Deferment
Periods, may be paid monthly or quarterly or capitalized (added to the
principal balance) not more frequently than quarterly.

  Disbursement

    Loans made under the Federal Family Education Loan Program (except
Consolidation Loans) generally must be disbursed in two or more installments,
none of which may exceed 50% of the total principal amount of the loan.

  Fees

    Guarantee Fee.  A Guarantee Agency is authorized to charge a premium, or
guarantee fee, of up to 1% of the principal amount of the loan, which must be
deducted proportionately from each installment payment of the proceeds of the
loan to the borrower.  Guarantee fees may not currently be charged to
borrowers of Consolidation Loans.  However, lenders may be charged an
insurance fee to cover the costs of increased or extended liability with
respect to Consolidation Loans.  For loans made prior to July 1, 1994, the
maximum guarantee fee was 3% of the principal amount of the loan, but no such
guarantee fee was authorized to be charged with respect to Unsubsidized
Stafford Loans.

    Origination Fee.  An eligible lender is authorized to charge the borrower
of a Stafford or Plus Loan an origination fee in an amount not to exceed 3% of
the principal amount of the loan, and is required to charge the borrower of an
Unsubsidized Stafford Loan an origination fee in the amount of 3% of the
principal amount of the loan.  These fees must be deducted proportionately
from each installment payment of the loan proceeds prior to payment to the borro
wer and are not retained by the eligible lender, but must be passed on to the
Secretary of Education.  For loans made prior to July 1, 1994, the maximum
authorized fee for Stafford, Plus and SLS Loans was 5%, and the required fee
for Unsubsidized Stafford Loans was 6.5%, of the principal amount of the loan.

    Lender Origination Fee.  The lender of any loan under the Federal Family
Education Loan Program made on or after October 1, 1993 is required to pay to
the Secretary of Education a fee equal to 0.5% of the principal amount of such
loan.

                                      -88-
<PAGE>
 
    Rebate Fee on Consolidation Loans.  The holder of any Consolidation Loan
made on or after October 1, 1993 is required to pay to the Secretary of
Education a monthly fee equal to .0875% (1.05% per annum) of the principal
amount of, and accrued interest on, such Consolidation Loan.

  Loan Guarantees

    Under the Federal Family Education Loan Program, Guarantee Agencies are
required to guarantee the payment of not less than 100% of the principal
amount of loans made prior to October 1, 1993 and covered by their respective
guarantee programs.  For a description of the requirements for loans to be
covered by such guarantees, see "Description of the Guarantee Agencies".   The
1993 Amendments reduced the minimum percentage of the principal amount of
loans which a Guarantee Agency must pay to 98%, effective with respect to
loans made on or after October 1, 1993.  The Department of Education has taken
the position that a Guarantee Agency may not pay more than 98% of the
principal amount of and accrued interest on such a loan.  Under certain
circumstances, guarantees may be assumed by the Secretary of Education or
another Guarantee Agency.  See "Contracts with Guarantee Agencies" below.

CONTRACTS WITH GUARANTEE AGENCIES

    Under the Federal Family Education Loan Program, the Secretary of
Education is authorized to enter into guaranty and interest subsidy agreements
with Guarantee Agencies.  The Federal Family Education Loan Program provides
for reimbursements to Guarantee Agencies for default claims paid by Guarantee
Agencies, support payments to Guarantee Agencies for administrative and other
expenses, advances for a Guarantee Agency's reserve funds, and interest
subsidy payments and Special Allowance Payments to the holders of qualifying
student loans made pursuant to the Federal Family Education Loan Program.

    The 1992 Amendments gave the Secretary of Education certain oversight
powers over Guarantee Agencies.  Guarantee Agencies are required to maintain
their reserves at certain levels based on the amount of outstanding loans that
they have guaranteed.  If a Guarantee Agency falls below the required level in
two consecutive years, or its claims rate exceeds 9% in any year, or if the
Secretary determines that the agency's administrative or financial condition
jeopardizes its ability to meet its obligations, the Secretary can require the
Guarantee Agency to submit and implement a plan by which it will correct such
problem(s).  If a Guarantee Agency fails to timely submit an acceptable plan
or fails to improve its condition, or if the Secretary determines that the
Guarantee Agency is in danger of financial collapse, the Secretary may
terminate the Guarantee Agency's reimbursement contract.  The 1993 Amendments
broadened the circumstances under which the Secretary may terminate such
reimbursement contracts, to include a determination that such action is
necessary to protect the federal fiscal interest or to ensure continued
availability of student loans or a smooth transition to direct lending (See
"Direct Loans" below).

    The 1992 Amendments also added provisions authorizing the Secretary of
Education to assume the guarantee obligations of a Guarantee Agency.  The
Higher Education Act now provides that, if the Secretary terminates a
Guarantee Agency's agreements under the Federal Family Education Loan Program,
the Secretary shall assume responsibility for all functions of the Guarantee
Agency under its program.  To that end, the Secretary is authorized to, among
other options, transfer the guarantees to another Guarantee Agency or assume
the guarantees.  It also provides that in the event the Secretary has
determined that a Guarantee Agency is unable to meet its guarantee
obligations, holders of loans guaranteed by such Guarantee Agency may submit
claims directly to the Secretary for payment, unless the Secretary has
provided for the assumption of such guarantees by another Guarantee Agency.

  Federal Reimbursement

    A Guarantee Agency's right to receive federal reimbursements for various
guarantee claims paid by such Guarantee Agency is governed by the Higher
Education Act and various contracts entered into between Guarantee Agencies
and the Secretary of Education.  See "Description of the Guarantee Agencies --
Federal Agreements".

                                      -89-
<PAGE>
 
Under the Higher Education Act and the Federal Reimbursement Contracts, the
Secretary of Education currently agrees to reimburse a Guarantee Agency for
the amounts expended by the Guarantee Agency in the discharge of its guarantee
obligation (i.e., the unpaid principal balance of and accrued interest on
loans guaranteed by the Guarantee Agency, which loans are referred to herein
as "guaranteed loans") as a result of the default of the borrower.  With
respect to loans made prior to October 1, 1993, the Secretary currently agrees
to reimburse the Guarantee Agency for up to 100% of the amounts so expended.
The 1993 Amendments provide for reimbursement of a maximum of 98% of the
amount expended with respect to guaranteed loans made on or after October 1,
1993.  Depending on the claims rate experience of a Guarantee Agency, such
100% (or 98%) reimbursement may be reduced as discussed in the formula
described below. The Secretary of Education also agrees to repay 100% of the
unpaid principal plus applicable accrued interest expended by a Guarantee
Agency in discharging its guarantee obligation as a result of the bankruptcy,
death, or total and permanent disability of a borrower (or in the case of a
Plus Loan, the death of the student on behalf of whom the loan was borrowed),
or in certain circumstances, as a result of school closures, which
reimbursements are not to be included in the calculations of the Guarantee
Agency's Claims Rate experience for the purpose of federal reimbursement under
the Federal Reimbursement Contracts.

    The formula for computing the percentage of federal reimbursement under
the Federal Reimbursement Contracts is not accumulated over a period of years
but is measured by the amount of federal reimbursement payments in any one
federal fiscal year as a percentage of the original principal amount of loans
under the Federal Family Education Loan Program guaranteed by the Guarantee
Agency and in repayment at the end of the preceding fiscal year.  Under the
formula, federal reimbursement payments to a Guarantee Agency in any one
fiscal year not exceeding 5% of the original principal amount of loans in
repayment at the end of the preceding fiscal year are to be paid by the
Secretary of Education at 100% (or 98% for loans made on or after October 1,
1993). Beginning at any time during any fiscal year that federal reimbursement
payments exceed 5%, and until such time as they may exceed 9%, of the original
principal amount of loans in repayment at the end of the preceding fiscal
year, then reimbursement payments on claims submitted during that period are
to be paid at 90% (or 88% for loans made on or after October 1, 1993).
Beginning at any time during any fiscal year that federal reimbursement
payments exceed 9% of the original principal amount of loans in repayment at
the end of the preceding fiscal year, then such payments for the balance of
that fiscal year will be paid at 80% (or 78% for loans made on or after
October 1, 1993).  The original principal amount of loans in repayment for
purposes of computing reimbursement payments to a Guarantee Agency means the
original principal amount of all loans guaranteed by such Guarantee Agency
less: (1) guarantee payments on such loans, (2) the original principal amount
of such loans that have been fully repaid, and (3) the original principal
amount of such loans for which the first principal installment payment has not
become due or such first installment need not be paid because of a Deferment
Period.

    Under present practice, after the Secretary of Education reimburses a
Guarantee Agency for a default claim paid on guaranteed loan, the Guarantee
Agency continues to seek repayment from the borrower.  The Guarantee Agency
returns to the Secretary of Education payments that it receives from a
borrower after deducting and retaining (i) a percentage amount equal to the
complement of the reimbursement percentage in effect at the time the loan was
reimbursed, and (ii) an amount equal to 27% (or 18½% in the case of a
payment from the proceeds of a Consolidation Loan) of such payments for
certain administrative costs.  The Secretary of Education may, however,
require the assignment to the Secretary of defaulted guaranteed loans, in
which event no further collections activity need be undertaken by the
Guarantee Agency, and no amount of any recoveries shall be paid to the
Guarantee Agency.  Prior to the 1993 Amendments, the percentage of collections
which Guarantee Agencies could retain (as described in clause (ii) above) was
30%.

    A Guarantee Agency may enter into an addendum to its Interest Subsidy
Agreement (as hereinafter defined), which addendum provides for the Guarantee
Agency to refer to the Secretary of Education certain defaulted guaranteed
loans.  Such loans are then reported to the Internal Revenue Service to
"offset" any tax refunds which may be due any defaulted borrower. To the
extent that the Guarantee Agency has originally received less than 100%
reimbursement from the Secretary of Education with respect to such a referred
loan, the Guarantee Agency

                                      -90-
<PAGE>
 
will not recover any amounts subsequently collected by the federal government
which are attributable to that portion of the defaulted loan for which the
Guarantee Agency has not been reimbursed.

  Rehabilitation of Defaulted Loans

    Under Section 428F of the Higher Education Act, the Secretary of Education
is authorized to enter into an agreement with a Guarantee Agency pursuant to
which the Guarantee Agency shall sell defaulted loans that are eligible for
rehabilitation to an eligible lender. The Guarantee Agency shall repay the
Secretary of Education an amount equal to 81.5% of the then current principal
balance of such loan, multiplied by the reimbursement percentage in effect at
the time the loan was reimbursed. The amount of such repayment shall be
deducted from the amount of federal reimbursement payments for the fiscal year
in which such repayment occurs, for purposes of determining the reimbursement
rate for that fiscal year.

    For a loan to be eligible for rehabilitation, the Guarantee Agency must
have received consecutive payments for 12 months of amounts owed on such loan.
Upon rehabilitation, a loan is eligible for all the benefits under the Higher
Education Act for which it would have been eligible had no default occurred
(except that a borrower's loan may only be rehabilitated once).

  Eligibility for Federal Reimbursement

    To be eligible for federal reimbursement payments, guaranteed loans must
be made by an eligible lender under the applicable Guarantee Agency's
Guarantee Program, which must meet requirements prescribed by the rules and
regulations promulgated under the Higher Education Act, including the borrower
eligibility, loan amount, disbursement, interest rate, repayment period and
guarantee fee provisions described herein and the other requirements set forth
in Section 428(b) of the Higher Education Act.

    Under the Higher Education Act, a guaranteed loan must be delinquent for
180 days if it is repayable in monthly installments or 240 days if it is
payable in less frequent installments before a lender may obtain payment on a
guarantee from the Guarantee Agency.  The Guarantee Agency must pay the lender
for the defaulted loan prior to submitting a claim to the Secretary of
Education for reimbursement. The Guarantee Agency must submit a reimbursement
claim to the Secretary of Education within 45 days after it has paid the
lender's default claim.  As a prerequisite to entitlement to payment on the
guarantee by the Guarantee Agency, and in turn payment of reimbursement by the
Secretary of Education, the lender must have exercised reasonable care and
diligence in making, servicing and collecting the Guaranteed Loan.

  Federal Interest Subsidy Payments

    Interest subsidy payments are interest payments paid with respect to an
eligible loan during the period prior to the time that the loan enters
repayment and during Grace and Deferment Periods.  The Secretary of Education
and the Guarantee Agencies entered into the Interest Subsidy Agreements as
described in "Description of the Guarantee Agencies -- Federal Agreements",
whereby the Secretary of Education agrees to pay interest subsidy payments to
the holders of eligible guaranteed loans for the benefit of students meeting
certain requirements, subject to the holders' compliance with all requirements
of the Higher Education Act.  Only Stafford Loans, and Consolidation Loans for
which the application was received on or after January 1, 1993, are eligible
for interest subsidy payments.  Consolidation Loans made after August 10, 1993
are eligible for interest subsidy payments only if all loans consolidated
thereby are Stafford Loans, except that Consolidation Loans for which the
application is received by an eligible lender on or after November 13, 1997
and before October 1, 1998, are eligible for interest subsidy payments on that
portion of the Consolidation Loan that repays Stafford Loans or similar
subsidized loans made under the direct loan program.  In addition, to be
eligible for interest subsidy payments, guaranteed loans must be made by an
eligible lender under the applicable Guarantee Agency's Guarantee Program, and
must meet requirements prescribed by the rules and regulations promulgated
under the Higher Education Act, including the

                                      -91-
<PAGE>
 
borrower eligibility, loan amount, disbursement, interest rate, repayment
period and guarantee fee provisions described herein and the other
requirements set forth in Section 428(b) of the Higher Education Act.

    The Secretary of Education makes interest subsidy payments quarterly on
behalf of the borrower to the holder of a guaranteed loan in a total amount
equal to the interest which accrues on the unpaid principal amount prior to
the commencement of the repayment period of the loan or during any Deferment
Period.  A borrower may elect to forego interest subsidy payments, in which
case the borrower is required to make interest payments.

  Federal Administrative Expense Allowances

    Prior to the adoption of the 1993 Amendments, each Guarantee Agency was
entitled to receive from the Secretary of Education an administrative cost
allowance equal to 1% of the total principal amount of the loans (other than
Consolidation Loans) guaranteed by the Guarantee Agency in any fiscal year,
for the purposes of administrative costs of pre-claims assistance for default
prevention and collection of defaulted guaranteed loans, administrative costs
of promoting commercial lender participation, administrative costs of
monitoring the enrollment and repayment status of students, and for other such
costs related to the Guarantee Agency's Guarantee Program.  The 1993
Amendments repealed such entitlement, effective October 1, 1993.  The 1993
Amendments, however, authorized payments for transition support (including
administrative costs) to Guarantee Agencies, in connection with the transition
to direct lending.  See "Direct Loans" below.  Budget legislation adopted
since that time has provided for the payment to Guarantee Agencies of an
administrative expense allowance equal to 0.85% of the agency's annual new
guarantee volume.  The 1997 Amendments provide for payment of such an
administrative expense allowance through the fiscal year ending September 30,
2002.  However, after the fiscal year ending September 30, 1997, such amounts
are subject to decreasing aggregate limits.  There are no assurances as to the
level of such payments that can be made within such aggregate limits, or that
Congress will require such payments or that the Secretary of Education will
determine to continue to make any such payments in future years.

  Federal Advances

    Pursuant to agreements entered into between the Guarantee Agencies and the
Secretary of Education under Sections 422 and 422(c) of the Higher Education
Act, the Secretary of Education was authorized to advance moneys from time to
time to the Guarantee Agencies for the purpose of establishing and
strengthening the Guarantee Agencies' reserves.  Section 422(c) currently
authorizes the Secretary of Education to make advances to Guarantee Agencies
in various circumstances, on terms and conditions satisfactory to the
Secretary, including if the Secretary is seeking to terminate the Guarantee
Agency's reimbursement contract or assume the Guarantee Agency's functions, to
assist the Guarantee Agency in meeting its immediate cash needs or to ensure
the uninterrupted payment of claims.

FEDERAL SPECIAL ALLOWANCE PAYMENTS

    The Higher Education Act provides for the payment by the Secretary of
Education of additional subsidies, called Special Allowance Payments, to
holders of qualifying student loans.  The amount of the Special Allowance
Payments, which are made on a quarterly basis, is computed by reference to the
average of the bond equivalent rates of the 91-day Treasury bills auctioned
during the preceding quarter (the "91-day T-Bill Rate").  The quarterly rate
for Special Allowance Payments for Student Loans made on or after October 1,
1981, and generally before November 16, 1986 is computed by subtracting the
applicable interest rate on such loans from the 91-day T-Bill Rate, adding
3.5% to the resulting per centum, and dividing the resulting per centum by
four.  For loans disbursed on or after November 16, 1986, or loans to cover
the costs of instruction for periods of enrollment beginning on or after
November 16, 1986, the 1986 Amendments and 1987 Amendments substituted 3.25%
for 3.5% in the foregoing formula.  For loans disbursed on or after October 1,
1992, the 1992 Amendments substituted 3.1% for 3.5% in such formula.  For
Stafford and Unsubsidized Stafford Loans made on or after July 1, 1995, the
1993 Amendments substitute 2.5% for 3.1% in such formula prior to the time
such loans enter repayment and during any Deferment Periods.  For loans made
on or after July 1, 1998, the special allowance formula is to be revised

                                      -92-
<PAGE>
 
similarly to the manner in which the applicable interest rate formula is
revised, as described above under "Loan Terms -- Interest Rates -- Stafford
Loans".

    For Plus and SLS Loans which bear interest at rates adjusted annually,
Special Allowance Payments are made only in years during which the interest
rate ceiling on such loans operates to reduce the rate that would otherwise
apply based upon the applicable formula.  See "Loan Terms -- Interest Rates --
Plus Loans" and "-- SLS Loans" above.  Under the 1993 Amendments, Special
Allowance Payments are paid with respect to Plus Loans made on or after July
1, 1994 only if the rate that would otherwise apply exceeds 10% per annum,
notwithstanding that the interest rate ceiling on such loans is 9% per annum.
The portion, if any, of a Consolidation Loan that repaid a loan made under the
federal health education assistance loan program may be ineligible for Special
Allowance Payments.

    Section 438(b)(2) of the Higher Education Act provides that the quarterly
rate of Special Allowance Payments paid to holders of loans which were made or
purchased with funds obtained by the holder from the issuance of certain
obligations, the income from which is exempt from taxation under the Code (as
well as with funds obtained by the holder from certain earnings related
thereto) shall be one-half the quarterly rate of the special allowance
established under the formula described above (without giving effect to the
changes in such formula enacted by the 1986 Amendments, the 1987 Amendments,
the 1992 Amendments and the 1993 Amendments). Such reduced rate, however,
shall not be less than:  (a) for loans disbursed before October 1, 1992, 2.5%
per annum in the case of loans for which the applicable interest rate is 7%
per annum, 1.5% per annum in the case of loans for which the applicable
interest rate is 8% per annum, or 0.5% per annum in the case of loans for
which the applicable rate is 9% per annum; and (b) for loans disbursed on or
after October 1, 1992, the difference between 9.5% per annum and the
applicable interest rate on the loan.  The effect of these provisions is to
provide a minimum rate of return (i.e., combined interest and Special
Allowance Payments) of 9.5% per annum on 7%, 8% and 9% Stafford Loans, on
Consolidation Loans, and on Stafford and Unsubsidized Stafford Loans that bear
interest at a rate that is adjusted annually and that were made on or after
October 1, 1992 .  However, Plus and SLS Loans do not have such an assured
rate of return because Special Allowance Payments are made on such loans only
if the interest rate ceiling on such loans operates to limit the applicable
interest rate.  In addition, variable rate loans made before October 1, 1992
will not have such an assured minimum rate of return.  The "rebate" fee
payable with respect to Consolidation Loans (as described above under "Loan
Terms -- Fees -- Rebate Fee on Consolidation Loans") also has the effect of
reducing the rate of return on Consolidation Loans made on or after October 1,
1993.  The special provisions described above for holders of loans made or
purchased with funds obtained from the issuance of certain obligations, the
income from which is exempt from taxation, applies only to such obligations
issued on or before September 30, 1993, and obligations issued to refund such
obligations.

    The Balanced Budget and Deficit Control Act of 1985, as amended (known as
the "Gramm-Rudman Law") requires the President to issue a sequester order for
any federal fiscal year in which the projected budget exceeds the target for
that year.  A sequester order for any fiscal year would apply to loans made on
or after October 1 of that fiscal year.  The sequester order would change the
formula for calculating Special Allowance Payments for the first four Special
Allowance Payment periods relating to loans originally disbursed during that
fiscal year.  The special allowance formula would be reduced to the 91-day
T-Bill Rate plus 3.0% (for loans with a special allowance formula of the
91-day T-Bill Rate plus 3.1%).

    For the Trustee to be eligible to receive Special Allowance Payments with
respect to any loans which were made or purchased with funds obtained by the
issuance of obligations, the income from which is exempt from taxation under
the Code (such as the Tax Exempt Series 1998-1 Notes), the Original Issuer may
not engage in any pattern or practice which results in a denial of a
borrower's access to loans under the Higher Education Act because of the
borrower's race, sex, color, religion, national origin, age, handicap status,
income, attendance at a particular eligible institution within the area served
by the Original Issuer, length of the borrower's educational program, or the
borrower's academic year in school.

                                      -93-
<PAGE>
 
    The Higher Education Act also provides that no special allowance may be
paid for such loans unless the Original Issuer submitted to the Governor of
the State a plan for doing business, for approval by the Governor after
consultation with EAC.  Such plan is required to contain provisions designed
to assure that:

         (1)  no eligible lender in the area served by the Original Issuer
    will be excluded from participation in the program of the Original Issuer
    and that all eligible lenders may participate in the program on the same
    terms and conditions if eligible lenders are going to participate in the
    program;

         (2)  no director or staff member of the Original Issuer who receives
    compensation from the Original Issuer may own stock in, or receive
    compensation from any agency that would contract to service and collect
    the loans of the Original Issuer;

         (3)  the Original Issuer will not purchase student loans from
    participating lenders at a premium amounting to more than 1% of the unpaid
    principal amount borrowed plus accrued interest to the date of
    acquisition, but the Original Issuer may pay reasonable loan transfer
    fees;

         (4)  the Original Issuer will, within the limit of funds available
    and subject to applicable State and federal law, make loans to, or
    purchase loans incurred by, all eligible students who are residents of or
    who attend an eligible institution within the area served by the Original
    Issuer;

         (5)  the Original Issuer has a plan under which it will pursue the
    development of new lender participation in a continuing program of
    benefits to students together with assurances of existing lender
    commitments to the program; and

         (6)  there will be an annual audit of the Original Issuer by a
    certified public accounting firm which will include review of compliance
    by the Original Issuer with the provisions of the plan.

    The Governor of the State has approved the Original Issuer's most recent
Plan for Doing Business.  Because the Original Issuer expects to terminate its
participation in the Federal Family Education Loan Program, the Original
Issuer will no longer be capable of carrying out certain provisions of such
plan for doing business.  The Original Issuer, SLFC, and the Corporation will
each covenant to comply with the provisions of such plan for doing business
that apply to their respective operations.

    The Department of Education's regulations impose various sanctions on
holders of such loans for failure to comply with the plan for doing business
and such regulations, including, without limitation, withholding or seeking
reimbursement of Special Allowance Payments.

    The Higher Education Act provides that if Special Allowance Payments or
interest subsidy payments have not been made within 30 days after the
Secretary of Education receives an accurate, timely and complete request
therefor, the special allowance payable to such holder shall be increased by
an amount equal to the daily interest accruing on the special allowance and
interest subsidy payments due the holder.

    Special Allowance Payments and interest subsidy payments are reduced by
the amount which the lender is authorized or required to charge as an
origination fee, as described above under "Loan Terms -- Fees -- Origination
Fee".  In addition, the amount of the lender origination fee described above
under "Loan Terms -- Fees -- Lender Origination Fees" is collected by offset
to Special Allowance Payments and interest subsidy payments.

FEDERAL STUDENT LOAN INSURANCE FUND

    The Higher Education Act authorizes the establishment of a Student Loan
Insurance Fund by the Federal government for making the federal insurance and
the federal reimbursement payments on defaulted student loans to Guarantee
Agencies.  If moneys in the fund are insufficient to make the federal payments
on defaults of such

                                      -94-
<PAGE>
 
loans, the Secretary of Education is authorized, to the extent provided in
advance by appropriation acts, to issue to the Secretary of the Treasury
obligations containing terms and conditions prescribed by the Secretary of
Education and approved by the Secretary of the Treasury, bearing interest at a
rate determined by the Secretary of the Treasury. The Secretary of the
Treasury is authorized and directed by the Higher Education Act to purchase
such obligations.

DIRECT LOANS

    The 1993 Amendments authorized a program of "direct loans", to be
originated by schools with funds provided by the Secretary of Education. Under
the direct loan program, the Secretary of Education is directed to enter into
agreements with schools, or origination agents in lieu of schools, to disburse
loans with funds provided by the Secretary.  Participation in the program by
schools is voluntary.  The goals set forth in the 1993 Amendments call for the
direct loan program to constitute 5% of the total volume of loans made under
the Federal Family Education Loan Program and the direct loan program for
academic year 1994-1995, 40% for academic year 1995-1996, 50% for academic
years 1996-1997 and 1997-1998 and 60% for academic year 1998-1999. No
provision is made for the size of the direct loan program thereafter. Based
upon information released by the General Accounting Office, participation by
schools in the direct loan program has not been sufficient to meet the goals
for the 1995-1996 or 1996-1997 academic years.

    The loan terms are generally the same under the direct loan program as
under the Federal Family Education Loan Program, though more flexible
repayment provisions are available under the direct loan program.  At the
discretion of the Secretary of Education, students attending schools that
participate in the direct loan program (and their parents) may still be
eligible for participation in the Federal Family Education Loan Program,
though no borrower could obtain loans under both programs.

    It is difficult to predict the impact of the direct lending program. There
is no way to accurately predict the number of schools that will participate in
future years, or, if the Secretary authorizes students attending participating
schools to continue to be eligible for Federal Family Education Loan Program
loans, how many students will seek loans under the direct loan program instead
of the Federal Family Education Loan Program.  In addition, it is impossible
to predict whether future legislation will eliminate, limit or expand the
direct loan program or the Federal Family Education Loan Program.


                    DESCRIPTION OF THE GUARANTEE AGENCIES

GENERAL

    The Indenture permits the Financing of Eligible Loans guaranteed by
various Guarantee Agencies.  The Corporation expects that of the Eligible
Loans to be Financed on the Date of Issuance with the proceeds of the Series
1998-1 Notes, approximately 60.2% will be guaranteed by Education Assistance
Corporation ("EAC"), approximately 33.4% will be guaranteed by Pennsylvania
Higher Education Assistance Agency ("PHEAA"), and the remainder will be
guaranteed by one of the following Guarantee Agencies: United Student Aid
Funds, Inc., Northstar Guarantee Inc., Great Lakes Higher Education
Corporation, Student Loans of North Dakota, Iowa College Aid Commission,
Missouri Coordinating Board for Higher Education, Illinois Student Aid
Commission, or Educational Credit Management Corporation (formerly known as
Transitional Guaranty Agency, Inc.).  The Corporation expects that California
Student Aid Commission also will be a Guarantee Agency for Eligible Loans to
be Financed following the Date of Issuance.  Any other state agency or private
nonprofit institution or organization which administers a Guarantee Program,
may also be a Guarantee Agency of Eligible Loans to be Financed, subject to
confirmation of ratings on any Outstanding Unenhanced Notes or, if no
Unenhanced Notes are then Outstanding but Other Indenture Obligations are
Outstanding, consent of each Other Beneficiary holding such Outstanding Other
Indenture Obligations, as evidenced in writing to the Trustee by each such
Other Beneficiary.

                                      -95-
<PAGE>
 
    The Corporation expects that the percentage of Financed Eligible Loans
guaranteed by EAC will increase over time, while the percentage guaranteed by
PHEAA will decrease.  However, actual amounts guaranteed by these Guarantee
Agencies may vary from the Corporation's expectations.  Proceeds of Additional
Notes issued on a parity basis under the Indenture, moreover, may be used to
finance Eligible Loans guaranteed by these or other Guarantee Agencies in
amounts unrelated to the expected amount of loans guaranteed by a particular
Guarantee Agency that is Financed with the proceeds of the Series 1998-1
Notes.  (Any Additional Notes will not be issued and sold under the
Registration Statement filed with respect to the Series 1998-1 Notes.)

    A Guarantee Agency guarantees loans made to students or parents of
students by lending institutions such as banks, credit unions, savings and
loan associations, certain schools, pension funds and insurance companies.  A
Guarantee Agency generally purchases defaulted student loans which it has
guaranteed from its cash and reserves (generally referred to herein as its
"Guarantee Fund").  A lender may submit a default claim to the Guarantee
Agency after the student loan has been delinquent for at least 180 days;
however, lenders are strongly encouraged not to file a claim until the loan is
at least 210 days delinquent.  The default claim package must include all
information and documentation required under the Federal Family Education Loan
Program regulations and the Guarantee Agency's policies and procedures.  Under
the Guarantee Agencies' current procedures, assuming that the default claim
package complies with the Guarantee Agency's loan procedures manual or
regulations, the Guarantee Agency pays the lender for a default claim within
90 days of the lender's filing the claim with the Guarantee Agency.  The
Guarantee Agency will pay the lender interest accrued on the loan for up to
360 days after delinquency.  The Guarantee Agency must file a reimbursement
claim with the Department of Education within 45 days after the Guarantee
Agency has paid the lender for the default claim.

    In general, a Guarantee Agency's Guarantee Fund has been funded
principally by administrative cost allowances paid by the Secretary of
Education, guarantee fees paid by lenders (the cost of which may be passed on
to borrowers), investment income on moneys in the Guarantee Fund, and a
portion of the moneys collected from borrowers on Guaranteed Loans that have
been reimbursed by the Secretary of Education to cover the Guarantee Agency's
administrative expenses.

    Various changes to the Higher Education Act have adversely affected the
receipt of revenues by the Guarantee Agencies and their ability to maintain
their Guarantee Funds at previous levels, and may adversely affect their
ability to meet their guarantee obligations.  These changes include the
reduction in reinsurance payments from the Secretary of Education because of
reduced reimbursement percentages; the reduction in maximum permitted
guarantee fees from 3% to 1% for loans made on or after July 1, 1994; the
reduction and possible elimination of administrative expense allowances from
the Secretary of Education; the reduction in supplemental preclaims assistance
payments from the Secretary of Education; and the reduction in retention by a
Guarantee Agency of collections on defaulted loans from 30% to 27%.
Additionally, the adequacy of a Guarantee Agency's Guarantee Fund to meet its
guarantee obligations with respect to existing student loans depends, in
significant part, on its ability to collect revenues generated by new loan
guarantees.  The Federal Direct Student Loan Program may adversely affect the
volume of new loan guarantees.  Future legislation may make additional changes
to the Higher Education Act that would significantly affect the revenues
received by Guarantee Agencies and the structure of the guarantee agency
program.  For a more complete description of provisions of the Higher
Education Act that relate to payments described in this paragraph or affect
the funding of a Guarantee Fund, see "Description of Federal Family Education
Loan Program".

    The Higher Education Act gives the Secretary of Education various
oversight powers over Guarantee Agencies.  These include requiring a Guarantee
Agency to maintain its Guarantee Fund at a certain required level and taking
various actions relating to a Guarantee Agency if its administrative and
financial condition jeopardizes its ability to meet its obligations.  These
actions include, among others, providing advances to the Guarantee Agency,
terminating the Guarantee Agency's Federal Reimbursement Contracts, assuming
responsibility for all functions of the Guarantee Agency, and transferring the
Guarantee Agency's guarantees to another guarantee agency or assuming such
guarantees.  The Higher Education Act provides that a Guarantee Agency's
Guarantee Fund shall be considered to be the property of the United States to
be used in the operation of the Federal Family Education

                                      -96-
<PAGE>
 
Loan Program or the Federal Direct Student Loan Program, and, under certain
circumstances, the Secretary of Education may demand payment of amounts in the
Guarantee Fund. The 1997 Amendments direct the Secretary of Education to
demand payment on September 1, 2002 of a total of one billion dollars from all
of the guarantee agencies participating in the Federal Family Education Loan
Program.  The amounts to be demanded of each Guarantee Agency shall be
determined in accordance with formulas included in the Higher Education Act.
Each Guarantee Agency will be required to deposit funds in a restricted
account in installments, beginning in the federal fiscal year ending September
30, 1998, to provide for such payment.  The Secretary has made the
determinations, and advised the Guarantee Agencies, of the amounts required to
be so transferred by the Guarantee Agencies. There can be no assurance that
relevant federal laws, including the Higher Education Act, will not be further
changed in a manner that may adversely affect the ability of a Guarantee
Agency to meet its guarantee obligations.  See "Description of Federal Family
Education Loan Program".

    There are no assurances as to the Secretary of Education's actions if a
Guarantee Agency encounters administrative or financial difficulties or that
the Secretary of Education will not demand that a Guarantee Agency transfer
additional portions or all of its Guarantee Fund to the Secretary of
Education.

    Information relating to the particular Guarantee Agencies set forth in
this Prospectus has been provided by the respective Guarantee Agencies, and
neither such information nor information included in the reports referred to
herein has been verified by, or is guaranteed as to accuracy or completeness
by, the Original Issuer, the Corporation or the Underwriters.  Such
information should not be construed as a representation by the Original
Issuer, the Corporation or the Underwriters.  No representation is made by the
Original Issuer, the Corporation or the Underwriters as to the accuracy or
adequacy of such information or the absence of material adverse changes in
such information subsequent to the dates thereof.

FEDERAL AGREEMENTS

    Each Guarantee Agency and the Secretary of Education have entered into
Federal Reimbursement Contracts pursuant to Section 428(c) of the Higher
Education Act (which include, for older Guarantee Agencies, a supplemental
contract pursuant to former Section 428A of the Higher Education Act), which
provide for the Guarantee Agency to receive 80% to 100% reimbursement of
insurance payments that the Guarantee Agency makes to eligible lenders with
respect to loans guaranteed by the Guarantee Agency prior to the termination
of the Federal Reimbursement Contracts or the expiration of the authority of
the Higher Education Act.  The 1993 Amendments reduced the reimbursement
percentages referred to above with respect to claims on most loans made on or
after October 1, 1993.  See "Effect of Annual Claims Rate" below.  The Federal
Reimbursement Contracts provide for termination under certain circumstances
and also provide for certain actions short of termination by the Secretary of
Education to protect the federal interest.  See "Description of Federal Family
Education Loan Program -- Contracts with Guarantee Agencies -- Federal
Reimbursement".

    In addition to guarantee benefits, qualified Student Loans acquired under
the Program benefit from certain federal subsidies.  Each Guarantee Agency and
the Secretary of Education have entered into an interest subsidy agreement
under Section 428(b) of the Higher Education Act (an "Interest Subsidy
Agreement"), which entitles the holders of eligible loans guaranteed by the
Guarantee Agency to receive interest subsidy payments from the Secretary of
Education on behalf of certain students while the student is in school, during
a six to twelve month Grace Period after the student leaves school, and during
certain Deferment Periods, subject to the holders' compliance with all
requirements of the Higher Education Act.  See "Description of Federal Family
Education Loan Program -- Contracts with Guarantee Agencies -- Federal
Interest Subsidy Payments" for a more detailed description of the interest
subsidy payments.

    United States Courts of Appeals have held that the federal government,
through subsequent legislation, has the right unilaterally to amend the
contracts between the Secretary of Education and the Guarantee Agencies
described herein.  Amendments to the Higher Education Act in 1986, 1987, 1992
and 1993, respectively (i) abrogated certain rights of guarantee agencies
under contracts with the Secretary of Education relating to the

                                      -97-
<PAGE>
 
repayment of certain advances from the Secretary of Education, (ii) authorized
the Secretary of Education to withhold reimbursement payments otherwise due to
certain guarantee agencies until specified amounts of such guarantee agencies'
reserves had been eliminated, (iii) added new reserve level requirements for
guarantee agencies and authorized the Secretary of Education to terminate the
Federal Reimbursement Contracts under circumstances that did not previously
warrant such termination, and (iv) expanded the Secretary of Education's
authority to terminate such contracts and to seize guarantee agencies'
reserves.  There can be no assurance that future legislation will not further
adversely affect the rights of the Guarantee Agencies, or holders of loans
guaranteed by a Guarantee Agency under such contracts.

EFFECT OF ANNUAL CLAIMS RATE

    A Guarantee Agency's ability to meet its obligation to pay default claims
on Financed Eligible Loans will depend on the adequacy of its Guarantee Fund
and, under the current federal reinsurance arrangement, the default experience
of all lenders under the Guarantee Agency's Guarantee Program.  A high default
experience among lenders participating in a Guarantee Agency's Guarantee
Program may cause the Guarantee Agency's Claims Rate (as defined below) for
its Guarantee Program to exceed the 5% and 9% levels described below, and
result in the Secretary of Education reimbursing the Guarantee Agency at lower
percentages of default claims payments made by the Guarantee Agency.

    Each Guarantee Agency is currently entitled to receive reimbursement
payments under the Federal Reimbursement Contracts in amounts that vary
depending on the Claims Rate experience of the Guarantee Agency.  The "Claims
Rate" is computed by dividing total default claims since the previous
September 30 by the total original principal amount of the Guarantee Agency's
guaranteed loans in repayment on such September 30.  On October 1 of each year
the Claims Rate begins at zero, regardless of the experience in preceding
years.  For loans made prior to October 1, 1993, if the Claims Rate remains
equal to or below 5% within a given federal fiscal year (October 1 through
September 30), the Secretary of Education is currently obligated to provide
100% reimbursement; if and when the Claims Rate exceeds 5% and until such
time, if any, as it exceeds 9% during the fiscal year, the reimbursement rate
is at 90%; if and when the Claims Rate exceeds 9% during the fiscal year, the
reimbursement rate for the remainder of the fiscal year is at 80%.  For loans
made prior to October 1, 1993, each Guarantee Agency is currently entitled to
at least 80% reimbursement from the Secretary of Education on default claims
that it purchases, regardless of its Claims Rate.  The reimbursement
percentages for loans made on or after October 1, 1993 are reduced from 100%,
90% and 80% to 98%, 88% and 78%, respectively.  See "Description of Federal
Family Education Loan Program".

    The Claims Rates for EAC and PHEAA for each of the last five federal
fiscal years is set forth in the table under "Certain Historical Information
for Guarantee Agencies -- Claims Rate" below.

EDUCATION ASSISTANCE CORPORATION - EAC

    EAC is a South Dakota nonprofit corporation organized in 1978 to
administer the guaranteed loan program in the State.  Since 1983, EAC also has
provided student loan guarantees and other services to certain lenders,
borrowers and schools in other states.  EAC has no members.  Two of the
present seven members of the Board of Directors of EAC are presently members
of the Boards of Directors of the Original Issuer, the Corporation and SLFC.
EAC presently employs a staff of 57 persons, plus part time help employed on a
periodic basis.

    From January 16, 1979 through September 30, 1997, EAC had guaranteed
approximately $1,170,594,000 principal amount of loans under the Higher
Education Act, of which EAC estimates that approximately $573,861,000
aggregate unpaid principal amount was outstanding as of September 30, 1997. As
of September 30, 1997, EAC had total assets of approximately $17,294,000,
total liabilities of approximately $8,767,000, total deferred revenue of
approximately $5,382,000 and retained earnings of approximately $3,145,000.
The Secretary of Education has advised EAC that, pursuant to the 1997
Amendments, EAC must pay $5,903,366 to the Secretary of Education on September
1, 2002 (and make annual restricted account deposits toward such payment
beginning

                                      -98-
<PAGE>
 
in fiscal year 1998 of approximately $1,181,000).  EAC's liabilities as of
September 30, 1997 include the entire amount ($5,903,666) that will be
required to be paid to the Secretary of Education under the 1997 Amendments.
See "General" above.  EAC will provide a copy of its most recent annual report
upon receipt of a written request directed to Education Assistance
Corporation, 115 First Avenue, Southwest, Aberdeen, South Dakota 57401,
Attention: President.

     EAC ceased issuing new loan guarantees as of December 22, 1987 in
connection with the enactment of the Omnibus Budget Reconciliation Act of 1987
and EAC's related dispute with the Secretary of Education concerning EAC's
right to retain its reserves.  In January 1988, EAC entered into an
arrangement with PHEAA, whereby EAC processed applications and guarantee
claims and undertook other administrative tasks with respect to loans made
after December 21, 1987 that EAC would otherwise have guaranteed, and PHEAA
guaranteed such loans.  EAC recommenced guaranteeing student loans in July
1991, around which time PHEAA ceased guaranteeing South Dakota loans pursuant
to this arrangement.  In May 1997, EAC recommenced guaranteeing loans to
borrowers neither resident in South Dakota nor attending school in South
Dakota, and ceased its arrangement with PHEAA with respect to such loans.

     EAC has created Educational Assistance Service Company, Inc. ("EASCI"), a
wholly-owned subsidiary of EAC, the primary purpose of which is to furnish a
complete range of loan origination, processing, monitoring and related
services with respect to student loans made under the federal guaranteed
student loan program. EASCI commenced operations on March 6, 1985.  As of
September 30, 1997, EASCI provided services to 138 lenders for a portfolio of
approximately $226,625,000 outstanding principal amount. The persons that
presently constitute EAC's Board of Directors also are the Directors of
EASCI.  EAC shares some personnel, office space, overhead and computer time
with EASCI.

PENNSYLVANIA HIGHER EDUCATION ASSISTANCE AGENCY - PHEAA

     PHEAA is a body corporate and politic constituting a public corporation
and government instrumentality of the Commonwealth of Pennsylvania (the
"Commonwealth") created pursuant to the Act of August 7, 1963, P.L. 549 (as
amended, the "PHEAA Act"). PHEAA's statutory purpose of improving higher
education opportunities by assisting students in meeting their expenses
involves a variety of activities, including administering numerous grant
programs, originating and purchasing student loans, servicing student loans
made by PHEAA and others and guaranteeing student loans.

     PHEAA is designated by the Secretary of Education as the Guarantee Agency
for the Commonwealth and for the States of West Virginia and Delaware.  PHEAA
has approximately 2,200 employees.  Its principal office is located in
Harrisburg, Pennsylvania, with six regional offices located throughout
Pennsylvania and additional offices located in California, West Virginia and
Delaware.

     PHEAA's activities are subject to audit by the Commonwealth's Department
of the Auditor General, and PHEAA is required to make an annual report to the
Governor of the Commonwealth and the legislature showing its condition at the
end of the Commonwealth's fiscal year.

     PHEAA will provide a copy of its most recent annual report upon receipt
of a written request directed to Pennsylvania Higher Education Assistance
Agency, 1200 North 7th Street, Harrisburg, Pennsylvania 17102-1444, Attention:
Timothy A. Guenther, Senior Vice President and Chief Financial Officer.

     The PHEAA Act created an educational loan assistance fund within the
State Treasury (the "Educational Loan Assistance Fund"). The PHEAA Act
provides that this fund is a continuing fund in which may be deposited moneys
received from repayments of principal on loans from the fund and payments of
interest and other fees and charges with respect to loans made pursuant to the
PHEAA Act, insurance premiums and charges assessed and collected by PHEAA on
loans made from the fund, appropriations made to the fund by the legislature,
proceeds of the sale of notes, bonds or other indebtedness to the extent and
in the manner provided by resolution of PHEAA's

                                      -99-
<PAGE>
 
Board of Directors, other moneys received from any other source for the
purpose of this fund, and moneys received from the federal government for the
purpose of this fund or the PHEAA Act. The PHEAA Act further provides that,
except as otherwise provided for in any contracts with bondholders, all
appropriations and payments made into the Educational Loan Assistance Fund are
appropriated to the Board of Directors and may be applied and reapplied as the
Board of Directors shall direct and shall not be subject to lapsing.

     PHEAA is authorized to issue bonds or notes, with the approval of the
Governor of the Commonwealth, for the purpose of purchasing, making or
guaranteeing loans to students or parents, or to lending institutions or
postsecondary institutions to make student or parent loans. The PHEAA Act
provides that all accrued and future earnings from funds invested by the Board
of Directors and such other accrued and future nonappropriated funds,
including, but not limited to, those funds obtained from the federal
government, insurance premiums, charges assessed by PHEAA, loan servicing
revenues, and contributions for the same purpose shall be available to PHEAA
and shall be deposited in the State Treasury and may be utilized at the
discretion of the Board of Directors for carrying out any of the corporate
purposes of PHEAA. Upon the dissolution of PHEAA or the cession of its
activities, all the property and moneys of PHEAA in excess of its obligations
shall become the property of the Commonwealth.

     PHEAA has no power to pledge the credit or taxing power of the
Commonwealth or to make PHEAA debts payable out of any moneys except those of
PHEAA. Neither the faith and credit nor the taxing power of the Commonwealth
is pledged to the payment of any of PHEAA's obligations.

     For accounting purposes, PHEAA has divided the Educational Loan
Assistance Fund into a Higher Education Assistance Fund (the "Assistance
Fund") and a Revenue Bond Fund (the "PHEAA Bond Fund"). Appropriations,
revenues and expenditures allocable to all PHEAA's programs, other than assets
and expenditures relating to its tax-exempt revenue bond financings, are
allocated to the Assistance Fund. All assets included in the PHEAA Bond Fund
are pledged to particular bond and note issues of PHEAA and are not available
to meet guarantee or other obligations of PHEAA related to its other
programs.  As noted below, several obligations of PHEAA under certain bond and
note financings, though secured and collateralized by specified assets in
PHEAA's Bond Fund, are obligations not limited to such assets. Under those
financings, certain persons may seek recourse against the Assistance Fund.

     As of June 30, 1997, the Assistance Fund had total assets of
approximately $789 million, total liabilities of approximately $551 million,
and retained earnings of approximately $237 million.  PHEAA estimates that the
portion of its retained earnings that would be treated as its Guarantee Fund
under the Higher Education Act would be approximately $196 million.  The
Secretary of Education has advised PHEAA that, pursuant to the 1997
Amendments, PHEAA must pay $116.2 million to the Secretary of Education on
September 1, 2002 (and make annual restricted account deposits toward such
payment beginning in fiscal year 1998 of approximately $23.24 million).
PHEAA's liabilities as of June 30, 1997 do not include the amount that will be
required to be paid to the Secretary of Education under the 1997 Amendments.
See "General" above.  The PHEAA Bond Fund had total assets of approximately
$1.65 billion, total liabilities of approximately $1.55 billion and retained
earnings of approximately $52 million as of June 30, 1997.

     Substantially all of PHEAA's expenditures relating to the various grant
programs that it administers (other than administrative expenses) are derived
from appropriations from the Commonwealth.  In recent years, PHEAA has not
received any appropriations to cover its administrative expenses.  To meet
PHEAA's obligations under its servicing and guarantee programs, PHEAA has in
the past relied, and expects in the future to continue to rely, principally on
servicing fee revenues; income on various investments in the Assistance Fund
(including various types of student loans); and revenues generated by its
activity as a guarantee agency under the Higher Education Act, including
federal reimbursement payments, administrative cost allowances, student loan
insurance premiums, and retentions from collections on defaulted loans.  The
implementation of the new direct loan program or other modifications to the
Higher Education Act may reduce certain servicing fee revenues or income
generated by PHEAA's activity as a guarantee agency.

     PHEAA began guaranteeing student loans in 1964.  As of June 30, 1997,
PHEAA had guaranteed a total of approximately $20.0 billion principal amount
of student loans under the Higher Education Act.  Of that amount, PHEAA
estimates that approximately $13.3 billion original principal amount of such
loans was outstanding.  PHEAA initially guaranteed loans only to residents of
the Commonwealth or persons who planned to attend or were attending eligible
educational institutions in the Commonwealth.  In May 1986, PHEAA began
guaranteeing loans to borrowers that did not meet these residency requirements
pursuant to its national guarantee program.  Under the PHEAA Act, guarantee
payments on loans under PHEAA's national guarantee program (including Financed
Eligible Loans Guaranteed by PHEAA) may not be paid from funds appropriated by
the Commonwealth.   The annual amount of loans guaranteed by PHEAA pursuant to
its Guarantee Program has increased in each of the last three fiscal years.
PHEAA's claims rate for purposes of receiving federal reinsurance is described
above under "Effect of Annual Claims Rate".

     In addition to guaranteeing loans under the Higher Education Act, PHEAA
also operates certain guarantee programs for which it receives no federal
reinsurance.  PHEAA had outstanding guarantee obligations on such loans in the
amount of approximately $49 million as of June 30, 1997.

     PHEAA began servicing loans for lenders in 1973, under a contract with
Student Loan Marketing Association ("Sallie Mae") to service loans Sallie Mae
purchased from Pennsylvania banks and other lenders.  In 1974, PHEAA was
granted legislative authority to market its servicing system to other states
and lenders.  As a result, PHEAA now has contracts with Sallie Mae, state
agencies and commercial lenders throughout the United States.  PHEAA's two
principal servicing products are its full-servicing operation and its remote
servicing operation.  As of June 30, 1997, under PHEAA's full-servicing
program, it serviced approximately 1,145,000 accounts with a principal balance
of approximately $11.3 billion for more than 320 customers; and under its
remote servicing operation, it serviced approximately 700,000 accounts in an
aggregate principal amount of approximately $3.5 billion for four customers.
Servicing revenue generated from PHEAA's servicing of loans that it owns
accounted for approximately 25% of servicing revenues for the 12 months ended
June 30, 1997.  For the year then ended, one other customer accounted for
approximately 17% of servicing revenues.  PHEAA's management expects gross
servicing revenues to continue to increase.

     PHEAA's current servicing agreements have contractual terms at inception
ranging from three years to life of the loan.  Under PHEAA's servicing
agreements, PHEAA generally has agreed to reimburse customers for any claims,
losses, liabilities or expenses which arise out of or relate to PHEAA's acts
or omissions with respect to services provided under such agreements where the
final determination of PHEAA's liability is established by an arbitrator, by a
court of law of competent jurisdiction, or by way of settlement.  PHEAA must
rely on moneys in the Assistance Fund to cover expenditures necessary to meet
its contractual obligations under the servicing agreements, including any
potential liabilities.  PHEAA has developed a new servicing system in
consultation with the consulting firm Deloitte & Touche, IBM and servicing
clients.  Conversion to the new system began in the second quarter of 1995 and
is ongoing.

     PHEAA acts as an originator and secondary market for various types of
student loans, including loans it has guaranteed under the Higher Education
Act, loans insured by the United States Department of Health and Human
Services under the Health Education Assistance Loan Program, and loans which
are insured by PHEAA without any form of federal reinsurance. PHEAA has
financed most of its acquisitions and originations of student loans through
the issuance of student loan revenue bonds. PHEAA has, however, used moneys in
the Assistance Fund to finance student loans.  As of June 30, 1997, the
Assistance Fund contained the following approximate outstanding principal
amounts of student loans which are not otherwise pledged to secure PHEAA's
financings: $20.0 million of student loans which are not insured or reinsured;
$33.0 million of student loans guaranteed by PHEAA under the Higher Education
Act which are reinsured (approximately $22.5 million of which were
Consolidation Loans); and $5.6 million of health education assistance loans
which are federally insured.  Of those amounts, $1.3 million of student loans
guaranteed by PHEAA under the Higher Education Act which are federally
reinsured, are not eligible for federal interest subsidy payments or Special
Allowance Payments.  Other student loans owned by PHEAA in the Assistance Fund
and the PHEAA Bond Fund are pledged to certain financings and

                                     -101-
<PAGE>
 
unavailable to meet PHEAA's guarantee obligations.  As of such date,
approximately $154.4 million of the Assistance Fund was deposited with and
invested by the State Treasurer.

     PHEAA had outstanding debt and/or credit facilities (under which the
entire aggregate amount of funds available has not been drawn) in the amount
of approximately $2.2 billion as of June 30, 1997.  Although most of PHEAA's
debt issues are limited obligations of PHEAA, under certain circumstances,
PHEAA's reimbursement obligations to certain credit facility providers are not
limited to the assets pledged to those debt issues.  For instance, PHEAA is
party to several credit facilities relating to certain series of bonds
requiring purchase by PHEAA of specified student loans from the applicable
trust estate when a claim for insurance has been denied.  Such covenants are
sometimes general obligations of PHEAA.  Even if these financings are fully
collateralized, therefore, credit enhancement providers may be able to seek
repayment from the Assistance Fund.  None of the above referenced indebtedness
is general obligation debt of, or is backed by the faith, credit and taxing
power of, the Commonwealth or any of its political subdivisions.

     PHEAA is also a party to various sublease agreements and lease purchase
agreements in connection with debt financings used to provide funds for the
acquisition of office buildings, parking facilities, and equipment for PHEAA.
PHEAA's financial obligations under such agreements are payable from the
Assistance Fund.

CERTAIN HISTORICAL INFORMATION FOR GUARANTEE AGENCIES

          Set forth below is certain historical information with respect to
each Guarantee Agency that is expected to guaranty 6% or more of the Financed
Eligible Loans as of the Date of Issuance (EAC and PHEAA) and with respect to
all guarantors of loans under the Federal Family Education Loan Program.
Except as otherwise indicated below, the information regarding each Guarantee
Agency has been obtained from the Department of Education's Federal Fiscal
Year 1993 Loan Programs Data Book and FY94-FY96 Federal Student Loan Programs
Data Book (the "DOE Data Books").  Information for EAC and PHEAA relating to
the federal fiscal year ended September 30, 1997 was obtained from EAC and
PHEAA, respectively.  No independent verification of such information has been
or will be made by the Corporation, the Original Issuer or the Underwriters.

          Guarantee Volume.  The following table sets forth the approximate
aggregate principal amount of loans under the Federal Family Education Loan
Program that have first become committed to be guaranteed by EAC and PHEAA and
by all guarantors of such loans in each of the five federal fiscal years 1992
through 1996.  Such approximate amounts for EAC and PHEAA for the federal
fiscal year ended September 30, 1997 were $173.6 million and $2,208.6 million,
respectively.

          Reserve Ratio.  Each Guarantee Agency's reserve ratio is determined
by dividing its cumulative cash reserves by the original principal amount of
the outstanding loans it has agreed to guarantee.  The term "cumulative cash
reserves" refers to cash reserves plus (i) sources of funds (including
insurance premiums, state appropriations, federal advances, federal
reinsurance payments, administrative cost allowances, collections on claims
paid and investment earnings) minus (ii) uses of funds  (including claims paid
to lenders, operating expenses, lender fees, the Department's share of
collections on claims paid, returned advances and reinsurance fees).  The
"original principal amount of outstanding loans" consists of the original
principal amount of loans guaranteed by such Guarantee Agency minus (i) the
original principal amount of loans cancelled, claims paid, loans paid in full
and loan guarantees transferred from such Guarantee Agency to other
guarantors, plus (ii) the original principal amount of loan guarantees
transferred to such Guarantee Agency from other guarantors.  The following
table sets forth each of EAC's and PHEAA's cumulative cash reserves and their
corresponding reserve ratios and the national average reserve ratio for all
guarantors for the five federal fiscal years 1992 through 1996.  On May 21,
1997, EAC prepaid various long term borrowings in the aggregate principal
amount of $6,464,912, plus accrued interest in the amount of $122,745, thus
reducing its assets and liabilities as of such date by an aggregate amount of
$6,587,657. This resulted in EAC's cumulative cash reserve being reduced by
this amount.  EAC's cumulative cash reserves and reserve ratio as of September
30, 1997 were $12.8 million and 1.8%, and PHEAA's cumulative cash reserves and
reserve ratio as of September 30, 1997 were $189.3 million and 1.4%.

          Cumulative Recovery Rates.  A Guarantee Agency's cumulative recovery
rate is determined by dividing the cumulative aggregate amount recovered from
borrowers by such Guarantee Agency by the cumulative aggregate amount of
default claims paid by such Guarantee Agency as of the end of the applicable
federal fiscal year.  The table below sets forth the cumulative recovery rates
for EAC and PHEAA and the national average cumulative recovery rates for all
guarantors as of the end of the five federal fiscal years 1992 through 1996.
EAC's and PHEAA's cumulative recovery rates for the federal fiscal year ended
September 30, 1997 were 44.82% and 54.83%, respectively.  The Original
Issuer's management does not believe that cumulative recovery rates provide an
accurate indication of a guarantor's financial health.

     Loan Loss Reserve.  The DOE Data Books do not disclose whether any
guarantor has established a segregated loan loss reserve with respect to its
student loan guarantee obligations.  Accordingly, to the extent that a
guarantor has not established such a segregated loan loss reserve, if a
guarantor receives less than full reimbursement of its guarantee obligations
from the Department of Education, the guarantor would be forced to look to its
existing assets to satisfy any such guarantee obligations not so reimbursed.

Claims Rate in each of the five federal fiscal years shown in the Claims Rate

that they are currently unaware of any trends or conditions which would cause
their respective Claims Rate to exceed 5% and thereby result in less than
maximum reimbursement for reinsurance claims to the Department of Education.
Notwithstanding the above, no assurance can be made that any such trends will
continue or not deteriorate, or that any Guarantee Agency will receive full
reimbursement for reinsurance claims (or the full 98% maximum reimbursement

During the Initial Interest Period, each series of the Tax Exempt Auction Rate
Series 1998-1 Senior Notes will bear interest at the Auction Rate Series
1998-1 Senior Note Initial Interest Rate for such series.  Thereafter, the Tax
Exempt Auction Rate Series 1998-1 Senior Notes of each series will bear
interest at an Auction Rate Series 1998-1 Senior Note Interest Rate based on
an Auction Period generally consisting of 35 days, subject to adjustment as
described in "Auction of the Auction Rate Series 1998-1 Senior Notes --
Changes in Auction Terms -- Changes in Auction Period or Periods".  In no
event will the Auction Rate Series 1998-1 Senior Note Interest Rate exceed the
applicable Auction Rate Series 1998-1 Senior Note Interest Rate Limitation of
14% per annum.

     For each series of the Tax Exempt Auction Rate Series 1998-1 Senior Notes
during the Initial Interest Period and each Auction Period thereafter,
interest at the Auction Rate Series 1998-1 Senior Note Interest Rate will
accrue daily and will be computed for the actual number of days elapsed on the
basis of a year consisting of 360 days.  Interest due on the Tax Exempt
Auction Rate Series 1998-1 Senior Notes on any Interest Payment Date will be
calculated on a per unit basis, based on a unit of $100,000.

     The Auction Rate Series 1998-1 Senior Note Interest Rate to be borne by
each series of the Tax Exempt Auction Rate Series 1998-1 Senior Notes after
the Initial Interest Period for each Auction Period until an Auction Period
Adjustment, if any, will be determined as hereinafter described.  Each such
Auction Period will commence on and include the Thursday following the
expiration of the immediately preceding Auction Period and terminate on and
include the Wednesday immediately preceding the Thursday of the fifth
following week; provided, however, that in the case of the Auction Period that
immediately follows the Initial Interest Period for a series of the Tax Exempt
Auction Rate Series 1998-1 Senior Notes, such Auction Period will commence on
the Initial Interest Rate Adjustment Date for such series.  The Auction Rate
Series 1998-1 Senior Note Interest Rate on each series of the Tax Exempt
Auction Rate Series 1998-1 Senior Notes for each Auction Period will be the
Auction Rate in effect for such Auction Period as determined in accordance
with the Auction Procedures described in "Auction of the Series 1998-1 Senior
Notes"; provided that if, on any Interest Rate Determination Date, an Auction
is not held with respect to a series of Tax Exempt Auction Rate Series 1998-1
Senior Notes for any reason, then the Auction Rate Series 1998-1 Senior Note
Interest Rate on such series for the next succeeding Auction Period will be
the Maximum Auction Rate.

     Notwithstanding the foregoing:

          (A) if the ownership of a series of Tax Exempt Auction Rate Series
     1998-1 Senior Notes is no longer maintained in book-entry form, the
     Auction Rate Series 1998-1 Senior Note Interest Rate on the Tax Exempt
     Auction Rate Series 1998-1 Senior Notes of such series for any Interest
     Period commencing after the delivery of certificates representing the Tax
     Exempt Auction Rate Series 1998-1 Senior Notes of such series will equal
     the Maximum Auction Rate on the Business Day immediately preceding the
     first day of such subsequent Interest Period; or

          (B) if a Payment Default has occurred with respect to a series of
     Tax Exempt Auction Rate Series 1998-1 Senior Notes, the Auction Rate
     Series 1998-1 Senior Note Interest Rate on such series for the Interest
     Period for such series commencing on or immediately after such Payment
     Default and for each Interest Period thereafter, to and including the
     Interest Period, if any, during which, or commencing less than two
     Business Days after, such Payment Default is cured in accordance with the
     First Supplemental Indenture, will equal the Non-Payment Rate on the
     first day of each such Interest Period.

     In any event, no Auction will be held on any Auction Date under the First
Supplemental Indenture during the continuance of a Payment Default.

     The Auction Agent is to promptly give written notice to the Trustee and
the Corporation of each Auction Rate Series 1998-1 Senior Note Interest Rate
(unless the Auction Rate Series 1998-1 Senior Note Interest Rate is the
Non-Payment Rate) applicable to each series of the Tax Exempt Auction Rate
Series 1998-1 Senior Notes.  The Trustee is to notify the Holders of Tax
Exempt Auction Rate Series 1998-1 Senior Notes of the Auction Rate Series
1998-1 Senior Note Interest Rate applicable to each such series of Tax Exempt
Auction Rate Series 1998-1 Senior Notes for each Auction Period on the second
Business Day of such Auction Period.

     If the Auction Agent no longer determines, or fails to determine, when
required, the Auction Rate Series 1998-1 Senior Note Interest Rate with
respect to a series of Tax Exempt Auction Rate Series 1998-1 Senior Notes, or
if, for any reason, such manner of determination is held to be invalid or
unenforceable, the Auction Rate Series 1998-1 Senior Note Interest Rate for
the next succeeding Interest Period (which period will be an Auction Period
for such series of the Tax Exempt Auction Rate Series 1998-1 Senior Notes)
will be the Maximum Auction Rate as determined by the Auction Agent for such
next succeeding Auction Period, and if the Auction Agent fails or refuses to
determine said Maximum Auction Rate, the Maximum Auction Rate is to be
determined by a securities dealer appointed by the Corporation capable of
making such a determination in accordance with the provisions of the
Indenture, and written notice of such determination is to be given by such
securities dealer to the Trustee.

INTEREST LIMITED TO THE EXTENT PERMISSIBLE BY LAW

     In no event shall the cumulative amount of interest paid or payable on a
series of Tax Exempt Auction Rate Series 1998-1 Senior Notes exceed the amount
permitted by applicable law.  If the applicable law is ever judicially
interpreted so as to render usurious any amount called for under the Tax
Exempt Auction Rate Series 1998-1 Senior Notes of a series or related
documents or otherwise contracted for, charged, reserved, taken or received in
connection with the Tax Exempt Auction Rate Series 1998-1 Senior Notes of such
series, or if the call for redemption or acceleration of the maturity of the
Tax Exempt Auction Rate Series 1998-1 Senior Notes of such series results in
payment to or receipt by the Holder or any former Holder of the Tax Exempt
Auction Rate Series 1998-1 Senior Notes of such series of any interest in
excess of that permitted by applicable law, then, notwithstanding any
provision of the Tax Exempt Auction Rate Series 1998-1 Senior Notes of such
series or related documents to the contrary, all excess amounts theretofore
paid or received with respect to the Tax Exempt Auction Rate Series 1998-1
Senior Notes of such series shall be credited on the principal balance of the
Tax Exempt Auction Rate Series 1998-1 Senior Notes of such series (or, if the
Tax Exempt Auction Rate Series 1998-1 Senior Notes of such series have been
paid or would thereby be paid in full, refunded by the recipient thereof), and
the provisions of the Tax Exempt Auction Rate Series 1998-1 Senior Notes of
such series and related documents shall automatically

                                     -106-
<PAGE>
 
and immediately be deemed reformed and the amounts thereafter collectible
thereunder reduced, without the necessity of the execution of any new

                                     Initial Interest Rate

</TABLE>

During the Initial Interest Period, each series of the Taxable Auction Rate
Series 1998-1 Senior Notes will bear interest at the Auction Rate Series
1998-1 Senior Note Initial Interest Rate for such series.  Thereafter, except
with respect to an Auction Period Adjustment as described in "Auction of the
Auction Rate Series 1998-1 Senior Notes", the Taxable Auction Rate Series
1998-1 Senior Notes will bear interest at an Auction Rate Series 1998-1 Senior
Note Interest Rate based on an Auction Period generally consisting of 28 days,
subject to adjustment as described in "Auction of the Auction Rate Series
1998-1 Senior Notes -- Changes in Auction Terms -- Changes in Auction Period
or Periods".  In no event will the Series 1998-1 Senior Note Interest Rate
exceed the applicable Auction Rate Series 1998-1 Senior Note Interest Rate
Limitation of 18% per annum.

     Interest on each series of the Taxable Auction Rate Series 1998-1 Senior
Notes will be paid on the Business Day following each Auction Period for such
series.  For each series of the Taxable Auction Rate Series 1998-1 Senior
Notes during the Initial Interest Period and each Auction Period thereafter,
interest at the Auction Rate Series 1998-1 Senior Note Interest Rate will
accrue daily and will be computed for the actual number of days elapsed on the
basis of a year consisting of 360 days.

     The Auction Rate Series 1998-1 Senior Note Interest Rate to be borne by
each series of the Taxable Auction Rate Series 1998-1 Senior Notes after the
Initial Interest Period for each Auction Period until an Auction Period
Adjustment, if any, will be determined as hereinafter described.  Each such
Auction Period will commence on and include the first day following the
expiration of the immediately preceding Auction Period and terminate on and
include the day immediately preceding the second Business Day of the fourth
following week; provided, however, that in the case of the Auction Period that
immediately follows the Initial Interest Period for a series of the Taxable
Auction Rate Series 1998-1 Senior Notes, such Auction Period will commence on
the Initial Interest Rate Adjustment Date for such series.  The Auction Rate
Series 1998-1 Senior Note Interest Rate on each series of the Taxable Auction
Rate Series 1998-1 Senior Notes for each Auction Period will be the lesser of
(i) the Net Loan Rate in effect for such Auction Period and (ii) the Auction
Rate in effect for such Auction Period as determined in accordance with the
Auction Procedures described in "Auction of the Auction Rate Series 1998-1
Senior Notes"; provided that if, on any Interest Rate Determination Date, an
Auction is not held with respect to a series of the Taxable Auction Rate
Series 1998-1 Senior Notes for any reason, then the Auction Rate Series 1998-1
Senior Note Interest Rate on such series for the next succeeding Auction
Period will be the Net Loan Rate (subject to the applicable Auction Rate
Series 1998-1 Senior Note Interest Rate Limitation of 18%).

     Notwithstanding the foregoing:

          (A) if the ownership of a series of the Taxable Auction Rate Series
     1998-1 Senior Notes is no longer maintained in book-entry form, the
     Auction Rate Series 1998-1 Senior Note Interest Rate on the Taxable
     Auction Rate Series 1998-1 Senior Notes of such series for any Interest
     Period commencing after

                                     -108-
<PAGE>
 
     the delivery of certificates representing the Taxable Auction Rate Series
     1998-1 Senior Notes of such series will equal the lesser of (i) the
     Maximum Auction Rate and (ii) the Net Loan Rate; or

          (B) if a Payment Default has occurred with respect to a series of
     the Taxable Auction Rate Series 1998-1 Senior Notes, the Auction Rate
     Series 1998-1 Senior Note Interest Rate on such series for the Interest
     Period for such series commencing on or immediately after such Payment
     Default and for each Interest Period thereafter, to and including the
     Interest Period, if any, during which, or commencing less than two
     Business Days after, such Payment Default is cured in accordance with the
     First Supplemental Indenture, will equal the Non-Payment Rate on the
     first day of each such Interest Period.

     In any event, no Auction will be held on any Auction Date under the First
Supplemental Indenture on which there are insufficient moneys in the Note Fund
to pay, or otherwise held by the Trustee under the Indenture and available to
pay, the principal, if any, of and interest due on the Taxable Auction Rate
Series 1998-1 Senior Notes on the Interest Payment Date immediately following
such Auction Date.

     The Auction Agent is to promptly give written notice to the Trustee and
the Corporation of each Auction Rate Series 1998-1 Senior Note Interest Rate
(unless the Auction Rate Series 1998-1 Senior Note Interest Rate is the
Non-Payment Rate) and either the Auction Rate or the Net Loan Rate, as the
case may be, when such rate is not the Auction Rate Series 1998-1 Senior Note
Interest Rate, applicable to each series of the Taxable Auction Rate Series
1998-1 Senior Notes.  The Trustee is to notify the Holders of Taxable Auction
Rate Series 1998-1 Senior Notes of the Auction Rate Series 1998-1 Senior Note
Interest Rate applicable to each such series of Taxable Auction Rate Series
1998-1 Senior Notes for each Auction Period on the second Business Day of such
Auction Period.

     If the Auction Agent no longer determines, or fails to determine, when
required, the Auction Rate Series 1998-1 Senior Note Interest Rate with
respect to a series of Taxable Auction Rate Series 1998-1 Senior Notes, or, if
for any reason, such manner of determination is held to be invalid or
unenforceable, the Auction Rate Series 1998-1 Senior Note Interest Rate for
the next succeeding Interest Period (which period will be an Auction Period
for such series of the Taxable Auction Rate Series 1998-1 Senior Notes) will
be the Net Loan Rate for such next succeeding Auction Period.  The Net Loan
Rate with respect to each Interest Period commencing in a given month shall be
determined by or on behalf of the Corporation and written notice thereof given
to the Auction Agent at the time the Monthly Servicing Report for the second
preceding month is distributed.  If the Corporation fails or refuses to
determine such Net Loan Rate, the Net Loan Rate for any such Interest Period
shall be the most recently determined Net Loan Rate.

CARRY-OVER AMOUNTS ON THE TAXABLE AUCTION RATE SERIES 1998-1 SENIOR NOTES

     If the Auction Rate for a series of the Taxable Auction Rate Series
1998-1 Senior Notes is greater than the Net Loan Rate, then the Auction Rate
Series 1998-1 Senior Note Interest Rate applicable to such series for that
Interest Period will be the Net Loan Rate.  If the Auction Rate Series 1998-1
Senior Note Interest Rate for a series of Taxable Auction Rate Series 1998-1
Senior Notes for any Interest Period is the Net Loan Rate, the Trustee shall
determine the Carry-Over Amount, if any, with respect to such series for such
Interest Period.  Such determination of the Carry-Over Amount shall be made
separately for each series of Taxable Auction Rate Series 1998-1 Senior
Notes.  Each Carry-Over Amount shall bear interest calculated at a rate equal
to One-Month LIBOR (as determined by the Auction Agent, provided the Trustee
has received notice of One-Month LIBOR from the Auction Agent, and, if the
Trustee shall not have received such notice from the Auction Agent, then as
determined by the Trustee) from the Interest Payment Date for the Interest
Period with respect to which such Carry-Over Amount was calculated, until
paid.  Any payment in respect of Carry-Over Amount shall be applied, first, to
any accrued interest payable thereon and, thereafter, in reduction of such
Carry-Over Amount.  For purposes of the Indenture and the Taxable Auction Rate
Series 1998-1 Senior Notes, any reference to "principal" or "interest" therein
shall not include, within the meaning of such words, Carry-Over Amount or any
interest accrued on any such Carry-Over Amount.  Such Carry-Over Amount shall
be separately calculated for each Taxable Auction Rate Series 1998-1 Senior
Note of such series by the Trustee during such Interest Period in sufficient
time for the Trustee to give notice to each Holder of

                                     -109-
<PAGE>
 
such Carry-Over Amount as required in the next succeeding sentence.  On the
Interest Payment Date for an Interest Period with respect to which such
Carry-Over Amount has been calculated by the Trustee, the Trustee shall give
written notice to each Holder of the Carry-Over Amount applicable to such
Holder's Taxable Auction Rate Series 1998-1 Senior Note, which written notice
may accompany the payment of interest by check made to each such Holder on
such Interest Payment Date or otherwise shall be mailed on such Interest
Payment Date by first-class mail, postage prepaid, to each such Holder at such
Holder's address as it appears on the registration books maintained by the
Note Registrar.  Such notice shall state, in addition to such Carry-Over
Amount, that, unless and until a Taxable Auction Rate Series 1998-1 Senior
Notes has been redeemed or has been deemed no longer Outstanding under the
Indenture (after which all accrued Carry-Over Amount with respect to such
Taxable Auction Rate Series 1998-1 Senior Note (and all accrued interest
thereon) that remains unpaid shall be cancelled and no Carry-Over Amount (or
interest accrued thereon) shall be paid with respect to such Taxable Auction
Rate Series 1998-1 Senior Note), (i) the Carry-Over Amount (and interest
accrued thereon) shall be paid by the Trustee on such Taxable Auction Rate
Series 1998-1 Senior Note on the first occurring Interest Payment Date for a
subsequent Interest Period if and to the extent that (l) the Eligible
Carry-Over Make-Up Amount with respect to such Interest Period is greater than
zero, and (2) moneys are available pursuant to the terms of the First
Supplemental Indenture to pay such Carry-Over Amount (and interest accrued
thereon), and (ii) interest shall accrue on the Carry-Over Amount at a per
annum rate equal to One-Month LIBOR until such Carry-Over Amount is paid in
full or is cancelled.

     The Carry-Over Amount (and interest accrued thereon) for a series of the
Taxable Auction Rate Series 1998-1 Senior Notes shall be paid by the Trustee
on Outstanding Taxable Auction Rate Series 1998-1 Senior Notes of such series
on the first occurring Interest Payment Date for a subsequent Interest Period
if and to the extent that (i) the Eligible Carry-Over Make-Up Amount with
respect to such Interest Period is greater than zero, and (ii) moneys in the
Surplus Account are available on such Interest Payment Date for transfer to
the Interest Account for such purpose in accordance with the priorities
described in the second paragraph under "Summary of the Indenture -- Funds and
Accounts -- Surplus Fund", after taking into account all other amounts payable
from the Surplus Fund in accordance with such paragraph on such Interest
Payment Date.  Any Carry-Over Amount (and any interest accrued thereon) with
respect to any Taxable Auction Rate Series 1998-1 Senior Note which is unpaid
as of an Interest Payment Date, which Taxable Auction Rate Series 1998-1
Senior Note is to be called for redemption or deemed no longer Outstanding
under the First Supplemental Indenture on such Interest Payment Date, shall be
paid to the Holder thereof on such Interest Payment Date to the extent that
moneys are available therefor in accordance with the provisions of the
preceding sentence; provided, however, that any Carry-Over Amount (and any
interest accrued thereon) which is not so paid on such Interest Payment Date
shall be cancelled with respect to such Taxable Auction Rate Series 1998-1
Senior Note on such Interest Payment Date and shall not be paid on any
succeeding Interest Payment Date.  To the extent that any portion of the
Carry-Over Amount (and any interest accrued thereon) remains unpaid after
payment of a portion thereof, such unpaid portion shall be paid in whole or in
part until fully paid by the Trustee on the next occurring Interest Payment
Date or Dates, as necessary, for a subsequent Interest Period or Periods, if
and to the extent that the conditions in the first sentence of this paragraph
are satisfied.  On any Interest Payment Date on which the Trustee pays less
than all of the Carry-Over Amount (and any interest accrued thereon) with
respect to a Taxable Auction Rate Series 1998-1 Senior Note, the Trustee shall
give written notice in the manner set forth in the immediately preceding
paragraph to the Holder of such Taxable Auction Rate Series 1998-1 Senior Note
of the Carry-Over Amount remaining unpaid on such Taxable Auction Rate Series
1998-1 Senior Note.

     The Interest Payment Date on which any Carry-Over Amount for a series of
the Taxable Auction Rate Series 1998-1 Senior Notes will be paid is to be
determined by the Trustee as described in the immediately preceding paragraph,
and the Trustee is to make payment of the Carry-Over Amount in the same manner
as, and from the same Account from which, it pays interest on the Taxable
Auction Rate Series 1998-1 Senior Notes on an Interest Payment Date.  ANY
UNPAID CARRY-OVER AMOUNT, INCLUDING ANY ACCRUED AND UNPAID INTEREST THEREON,
ON A TAXABLE AUCTION RATE SERIES 1998-1 SENIOR NOTE NOT PAYABLE ON ANY
REDEMPTION DATE WITH RESPECT TO SUCH TAXABLE AUCTION RATE SERIES 1998-1 SENIOR
NOTE WILL BE FORFEITED UPON THE REDEMPTION (WHETHER PURSUANT TO

SUCH TAXABLE AUCTION RATE SERIES 1998-1 SENIOR NOTE, OR ON SUCH EARLIER

1998-1 SENIOR NOTE CEASES TO BE OUTSTANDING UNDER THE FIRST SUPPLEMENTAL
INDENTURE.  FITCH'S RATING ON THE TAXABLE AUCTION RATE SERIES 1998-1 SENIOR
NOTES WILL NOT APPLY TO ANY CARRY-OVER AMOUNT THAT MAY ACCRUE ON THE TAXABLE
AUCTION RATE SERIES 1998-1 SENIOR NOTES.

INTEREST LIMITED TO THE EXTENT PERMISSIBLE BY LAW

     In no event shall the cumulative amount of interest paid or payable on a
series of Taxable Auction Rate Series 1998-1 Senior Notes exceed the amount
permitted by applicable law.  If the applicable law is ever judicially
interpreted so as to render usurious any amount called for under the Taxable
Auction Rate Series 1998-1 Senior Notes of a series or related documents or
otherwise contracted for, charged, reserved, taken or received in connection
with the Taxable Auction Rate Series 1998-1 Senior Notes of such series, or if
the call for redemption or acceleration of the maturity of the Taxable Auction
Rate Series 1998-1 Senior Notes of such series results in payment to or
receipt by the Holder or any former Holder of the Taxable Auction Rate Series
1998-1 Senior Notes of such series of any interest in excess of that permitted
by applicable law, then, notwithstanding any provision of the Taxable Auction
Rate Series 1998-1 Senior Notes of such series or related documents to the
contrary, all excess amounts theretofore paid or received with respect to the
Taxable Auction Rate Series 1998-1 Senior Notes of such series shall be
credited on the principal balance of the Taxable Auction Rate Series 1998-1
Senior Notes of such series (or, if the Taxable Auction Rate Series 1998-1
Senior Notes of such series have been paid or would thereby be paid in full,
refunded by the recipient thereof), and the provisions of the Taxable Auction
Rate Series 1998-1 Senior Notes of such series and related documents shall
automatically and immediately be deemed reformed and the amounts thereafter
collectible thereunder reduced, without the necessity of the execution of any
new document, so as to comply with the applicable law, but so as to permit the
recovery of the fullest amount otherwise called for under the Taxable Auction
Rate Series 1998-1 Senior Notes of such series and under the related
documents.

INTEREST RATE ON THE TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTES

     During the Initial Interest Period for the Taxable LIBOR Rate Series
1998-1 Senior Notes, being the period from the date of delivery through March
1, 1998, the Taxable LIBOR Rate Series 1998-1 Senior Notes of each series will
bear interest at the Initial Interest Rate for such series.  The Taxable LIBOR
Rate Series 1998-1 Senior Note Interest Rate for each Interest Period after
the Initial Interest Period will be the Taxable LIBOR Rate Series 1998-1
Senior Note LIBOR-Based Rate based upon One-Month LIBOR plus the Taxable LIBOR
Rate Series 1998-1 Senior Note Spread, determined and subject to certain
limitations as hereinafter described.

     Interest on the Taxable LIBOR Rate Series 1998-1 Senior Notes shall be
computed on the basis of actual days elapsed and accrue daily from the date
thereof (on the basis of a 360-day year), and shall be payable on each
regularly scheduled Interest Payment Date with respect thereto (which shall be
the first Business Day of each calendar month, commencing March 2, 1998) prior
to the maturity thereof and at the maturity thereof.  The interest payable on
each Interest Payment Date for the Taxable LIBOR Rate Series 1998-1 Senior
Notes shall be that interest which has accrued through the last day of the
last complete Interest Period immediately preceding the Interest Payment Date
or, in the case of the maturity thereof, the last day preceding the date of
such maturity.  Each such Interest Period (other than the Initial Interest
Period) will commence on and include the first Business Day of a calendar
month and terminate on and include the last day preceding the next Interest
Rate Adjustment Date.  Each Interest Rate Adjustment Date shall be the
Interest Payment Date for the preceding Interest Period.  The Taxable LIBOR
Rate Series 1998-1 Senior Note Interest Rate shall be effective as of and on
the Interest Rate Adjustment Date of the applicable Interest Period and be in
effect thereafter through the end of such Interest Period.

     The interest rate to be borne by the Taxable LIBOR Rate Series 1998-1
Notes during each Interest Period after the Initial Interest Period shall be
determined on the related Interest Rate Determination Date and shall be equal
to the lesser of (i) the sum of One-Month LIBOR determined with respect to
such Interest Rate Determination Date plus the applicable Taxable LIBOR Rate
Series 1998-1 Senior Note Spread of 0.15% per annum (in the case of the Series
1998-1I Notes) or 0.20% per annum (in the case of the Series 1998-1J Notes),
as the case may be (which is herein referred to as the "Taxable LIBOR Rate
Series 1998-1 Senior Note LIBOR-Based Rate"), and (ii) the Net Loan Rate
determined with respect to such Interest Period.  The Trustee shall determine
such interest rate on each Interest Rate Determination Date and shall give the
Corporation written notice thereof prior to 2:00 p.m., New York City time, on
such Interest Rate Determination Date.  The Net Loan Rate with respect to each
Interest Period shall be determined by or on behalf of the Corporation and
written notice thereof given to the Trustee together with the Monthly
Servicing Report for the second preceding calendar month.  See "Carry-Over
Amounts on the Taxable LIBOR Rate Series 1998-1 Senior Notes" below.

     In the event that the Trustee no longer determines, or fails to
determine, when required, the Taxable LIBOR Rate Series 1998-1 Senior Note
LIBOR-Based Rate with respect to an Interest Rate Determination Date, or if,
for any reason, such manner of determination shall be held to be invalid or
unenforceable, the Taxable LIBOR Rate Series 1998-1 Senior Note LIBOR-Based
Rate for the related Interest Period shall be the Net Loan Rate as determined
with respect to such Interest Period.  If the Corporation shall fail or refuse
to determine such Net Loan Rate, the Net Loan Rate for such Interest Period
shall be the most recently determined Net Loan Rate.

CARRY-OVER AMOUNTS ON THE TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTES

     If the Taxable LIBOR Rate Series 1998-1 Senior Note LIBOR-Based Rate
determined with respect to a given Interest Period is greater than the Net
Loan Rate, then the Taxable LIBOR Rate Series 1998-1 Senior Note Interest Rate
for such Interest Period will be the Net Loan Rate.  If the Taxable LIBOR Rate
Series 1998-1 Senior Note Interest Rate for any Interest Period is the Net
Loan Rate, the Trustee shall determine the Carry-Over Amount, if any, with
respect to the Taxable LIBOR Rate Series 1998-1 Senior Notes for such Interest
Period.  Each such Carry-Over Amount shall bear interest calculated at a rate
equal to the Taxable LIBOR Rate Series 1998-1 Senior Note LIBOR-Based Rate (as
determined by the Trustee) from the Interest Payment Date for the Interest
Period with respect to which such Carry-Over Amount was calculated, until
paid.  Any payment in respect of Carry-Over Amount shall be applied, first, to
any accrued interest payable thereon and, thereafter, in reduction of such
Carry-Over Amount.  For purposes of the Indenture and the Taxable LIBOR Rate
Series 1998-1 Senior Notes, any reference to "principal" or "interest" therein
shall not include, within the meaning of such words, Carry-Over Amount or any
interest accrued on any such Carry-Over Amount.  Such Carry-Over Amount shall
be separately calculated for each Taxable LIBOR Rate Series 1998-1 Senior Note
by the Trustee during such Interest Period in sufficient time for the Trustee
to give notice to each Holder of such Carry-Over Amount as required in the
next succeeding sentence.  On the Interest Payment Date for an Interest Period
with respect to which such Carry-Over Amount has been calculated by the
Trustee, the Trustee shall give written notice to each Holder of the
Carry-Over Amount applicable to such Holder's Taxable LIBOR Rate Series 1998-1
Senior Note, which written notice may accompany the payment of interest by
check made to each such Holder on such Interest Payment Date or otherwise
shall be mailed on such Interest Payment Date by first-class mail, postage
prepaid, to each such Holder at such Holder's address as it appears on the
registration books maintained by the Note Registrar.  Such notice shall state,
in addition to such Carry-Over Amount, that, unless and until a Taxable LIBOR
Rate Series 1998-1 Senior Note has been redeemed or has been deemed no longer
Outstanding under the Indenture (after which all accrued Carry-Over Amount
with respect to such Taxable LIBOR Rate Series 1998-1 Senior Note (and all
accrued interest thereon) that remains unpaid shall be cancelled and no
Carry-Over Amount (or interest accrued thereon) shall be paid with respect to
such Taxable LIBOR Rate Series 1998-1 Senior Note), (i) the Carry-Over Amount
(and interest accrued thereon) shall be paid by the Trustee on such Taxable
LIBOR Rate Series 1998-1 Senior Note on the first occurring Interest Payment
Date for a subsequent Interest Period if and to the extent that (a) the
Eligible Carry-Over Make-Up Amount with respect to such Interest Period is
greater than zero, and (b) moneys are available pursuant to the terms of the
First Supplemental Indenture to pay such Carry-Over Amount (and interest
accrued thereon), and (ii) interest shall accrue on the Carry-Over Amount at a
per annum rate equal to the Taxable LIBOR Rate Series 1998-1 Senior Note
LIBOR-Based Rate until such Carry-Over Amount is paid in full or is cancelled.

     The Carry-Over Amount (and interest accrued thereon) for the Taxable
LIBOR Rate Series 1998-1 Senior Notes shall be paid by the Trustee on
Outstanding Taxable LIBOR Rate Series 1998-1 Senior Notes on the first
occurring Interest Payment Date for a subsequent Interest Period if and to the
extent that (a) the Eligible Carry-Over Make-Up Amount with respect to such
Interest Period is greater than zero, and (b) moneys in the Surplus Account
are available on such Interest Payment Date for transfer to the Interest
Account for such purpose in accordance with the second paragraph under
"Summary of the Indenture -- Funds and Accounts -- Surplus Account", after
taking into account all other amounts payable from the Surplus Fund in
accordance with such paragraph on such Interest Payment Date.  Any Carry-Over
Amount (and any interest accrued thereon) with respect to any Taxable LIBOR
Rate Series 1998-1 Senior Note which is unpaid as of an Interest Payment Date,
which Taxable LIBOR Rate Series 1998-1 Senior Note is to be called for
redemption or deemed no longer Outstanding under the First Supplemental
Indenture on such Interest Payment Date, shall be paid to the Holder thereof
on such Interest Payment Date to the extent that moneys are available therefor
in accordance with the provisions of the preceding clauses (a) and (b);
provided, however, that any Carry-Over Amount (and any interest accrued
thereon) which is not so paid on such Interest Payment Date shall be cancelled
with respect to such Taxable LIBOR Rate Series 1998-1 Senior Note on such
Interest Payment Date and shall not be paid on any succeeding Interest Payment
Date.  To the extent that any portion of the Carry-Over Amount (and any
interest accrued thereon) remains unpaid after payment of a portion thereof,
such unpaid portion shall be paid in whole or in part until fully paid by the
Trustee on the next occurring Interest Payment Date or Dates, as necessary,
for a subsequent Interest Period or Periods, if and to the extent that

                                     -113-
<PAGE>
 
the conditions in the first sentence of this paragraph are satisfied.  On any
Interest Payment Date on which the Trustee pays less than all of the
Carry-Over Amount (and any interest accrued thereon) with respect to a Taxable
LIBOR Rate Series 1998-1 Senior Note, the Trustee shall give written notice in
the manner set forth in the immediately preceding paragraph to the Holder of
such Taxable LIBOR Rate Series 1998-1 Senior Note of the Carry-Over Amount
remaining unpaid on such Taxable LIBOR Rate Series 1998-1 Senior Note.

     The Interest Payment Date on which any Carry-Over Amount (or any interest
accrued thereon) for the Taxable LIBOR Rate Series 1998-1 Senior Notes shall
be paid shall be determined by the Trustee in accordance with the provisions
of the immediately preceding paragraph, and the Trustee shall make payment of
the Carry-Over Amount (and any interest accrued thereon) in the same manner
as, and from the same Account from which, it pays interest on the Taxable
LIBOR Rate Series 1998-1 Senior Notes on an Interest Payment Date.  ANY UNPAID
CARRY-OVER AMOUNT, INCLUDING ANY ACCRUED AND UNPAID INTEREST THEREON, ON A
TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTE NOT PAYABLE ON ANY REDEMPTION
DATE WITH RESPECT TO SUCH TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTE WILL BE
FORFEITED UPON THE REDEMPTION OR AT MATURITY OF SUCH TAXABLE LIBOR RATE SERIES
1998-1 SENIOR NOTE, OR ON SUCH EARLIER INTEREST PAYMENT DATE, IF ANY, ON WHICH
SUCH TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTE CEASES TO BE OUTSTANDING
UNDER THE FIRST SUPPLEMENTAL INDENTURE.  FITCH'S RATING ON THE TAXABLE LIBOR
RATE SERIES 1998-1 SENIOR NOTES WILL NOT APPLY TO ANY CARRY-OVER AMOUNT THAT
MAY ACCRUE ON THE TAXABLE LIBOR RATE SERIES 1998-1 SENIOR NOTES.

INTEREST LIMITED TO THE EXTENT PERMISSIBLE BY LAW

     In no event shall the cumulative amount of interest paid or payable on
the Taxable LIBOR Rate Series 1998-1 Senior Notes exceed the amount permitted
by applicable law.  If the applicable law is ever judicially interpreted so as
to render usurious any amount called for under the Taxable LIBOR Rate Series
1998-1 Senior Notes or related documents or otherwise contracted for, charged,
reserved, taken or received in connection with the Taxable LIBOR Rate Series
1998-1 Senior Notes, or if the call for redemption or acceleration of the
maturity of the Taxable LIBOR Rate Series 1998-1 Senior Notes results in
payment to or receipt by the Holder or any former Holder of the Taxable LIBOR
Rate Series 1998-1 Senior Notes of any interest in excess of that permitted by
applicable law, then, notwithstanding any provision of the Taxable LIBOR Rate
Series 1998-1 Senior Notes or related documents to the contrary, all excess
amounts theretofore paid or received with respect to the Taxable LIBOR Rate
Series 1998-1 Senior Notes shall be credited on the principal balance of the
Taxable LIBOR Rate Series 1998-1 Senior Notes (or, if the Taxable LIBOR Rate
Series 1998-1 Senior Notes have been paid or would thereby be paid in full,
refunded by the recipient thereof), and the provisions of the Taxable LIBOR
Rate Series 1998-1 Senior Notes and related documents shall automatically and
immediately be deemed reformed and the amounts thereafter collectible
thereunder reduced, without the necessity of the execution of any new
document, so as to comply with the applicable law, but so as to permit the
recovery of the fullest amount otherwise called for under the Taxable LIBOR
Rate Series 1998-1 Senior Notes and under the related documents.

INTEREST RATE ON THE TAXABLE LIBOR RATE SERIES 1998-1 SUBORDINATE NOTES

     During the Initial Interest Period for the Taxable LIBOR Rate Series
1998-1 Subordinate Notes, being the period from the date of delivery through
March 1, 1998, the Taxable LIBOR Rate Series 1998-1 Subordinate Notes will
bear interest at the Initial Interest Rate for such series.  The Taxable LIBOR
Rate Series 1998-1 Subordinate Note Interest Rate for each Interest Period
after the Initial Interest Period for the Taxable LIBOR Rate Series 1998-1
Subordinate Notes will be the Taxable LIBOR Rate Series 1998-1 Subordinate
Note LIBOR-Based Rate based upon One-Month LIBOR plus the Taxable LIBOR Rate
Series 1998-1 Subordinate Note Spread, determined and subject to certain
limitations as hereinafter described.

     Interest on the Taxable LIBOR Rate Series 1998-1 Subordinate Notes shall
be computed on the basis of actual days elapsed and accrue daily from the date
thereof (on the basis of a 360-day year), and shall be payable on each
regularly scheduled Interest Payment Date with respect thereto (which shall be
the first Business Day of each calendar month, commencing March 2, 1998) prior
to the maturity thereof and at the maturity thereof.  The interest payable on
each Interest Payment Date for the Taxable LIBOR Rate Series 1998-1
Subordinate Notes shall

                                     -115-
<PAGE>
 
be that interest which has accrued through the last day of the last complete
Interest Period immediately preceding the Interest Payment Date or, in the
case of the maturity thereof, the last day preceding the date of such
maturity.  Each such Interest Period (other than the Initial Interest Period)
will commence on and include the first Business Day of a calendar month and
terminate on and include the last day preceding the next Interest Rate
Adjustment Date.  Each Interest Rate Adjustment Date shall be the Interest
Payment Date for the preceding Interest Period.  The Taxable LIBOR Rate Series
1998-1 Subordinate Note Interest Rate shall be effective as of and on the
Interest Rate Adjustment Date of the applicable Interest Period and be in
effect thereafter through the end of such Interest Period.

     The interest rate to be borne by the Taxable LIBOR Rate Series 1998-1
Subordinate Notes during each Interest Period after the Initial Interest
Period shall be determined on the related Interest Rate Determination Date and
shall be equal to the lesser of (i) the sum of One-Month LIBOR determined with
respect to such Interest Rate Determination Date plus the Taxable LIBOR Rate
Series 1998-1 Subordinate Note Spread of 0.40% per annum (which is herein
referred to as the "Taxable LIBOR Rate Series 1998-1 Subordinate Note
LIBOR-Based Rate"), and (ii) the Net Loan Rate determined with respect to such
Interest Period.  The Trustee shall determine such interest rate on each
Interest Rate Determination Date and shall give the Corporation written notice
thereof prior to 2:00 p.m., New York City time, on such Interest Rate
Determination Date.  The Net Loan Rate with respect to each Interest Period
shall be determined by or on behalf of the Corporation and written notice
thereof given to the Trustee together with the Monthly Servicing Report for
the second preceding calendar month.  See "Carry-Over Amounts on the Taxable
LIBOR Rate Series 1998-1 Subordinate Notes" below.

     In the event that the Trustee no longer determines, or fails to
determine, when required, the Taxable LIBOR Rate Series 1998-1 Subordinate
Note LIBOR-Based Rate with respect to an Interest Rate Determination Date, or
if, for any reason, such manner of determination shall be held to be invalid
or unenforceable, the Taxable LIBOR Rate Series 1998-1 Subordinate Note
LIBOR-Based Rate for the related Interest Period shall be the Net Loan Rate as
determined with respect to such Interest Period.  If the Corporation shall
fail or refuse to determine such Net Loan Rate, the Net Loan Rate for such
Interest Period shall be the most recently determined Net Loan Rate.

CARRY-OVER AMOUNTS ON THE TAXABLE LIBOR RATE SERIES 1998-1 SUBORDINATE NOTES

     If the Taxable LIBOR Rate Series 1998-1 Subordinate Notes LIBOR-Based
Rate determined with respect to a given Interest Period is greater than the
Net Loan Rate, then the Taxable LIBOR Rate Series 1998-1 Subordinate Note
Interest Rate for such Interest Period will be the Net Loan Rate.  If the
Taxable LIBOR Rate Series 1998-1 Subordinate Note Interest Rate for any
Interest Period is the Net Loan Rate, the Trustee shall determine the
Carry-Over Amount, if any, with respect to the Taxable LIBOR Rate Series
1998-1 Subordinate Notes for such Interest Period.  Each such Carry-Over
Amount shall bear interest calculated at a rate equal to the Taxable LIBOR
Rate Series 1998-1 Subordinate Note LIBOR-Based Rate (as determined by the
Trustee) from the Interest Payment Date for the Interest Period with respect
to which such Carry-Over Amount was calculated, until paid.  Any payment in
respect of Carry-Over Amount shall be applied, first, to any accrued interest
payable thereon and, thereafter, in reduction of such Carry-Over Amount.  For
purposes of the Indenture and the Taxable LIBOR Rate Series 1998-1 Subordinate
Notes, any reference to "principal" or "interest" therein shall not include,
within the meaning of such words, Carry-Over Amount or any interest accrued on
any such Carry-Over Amount.  Such Carry-Over Amount shall be separately
calculated for each Taxable LIBOR Rate Series 1998-1 Subordinate Note by the
Trustee during such Interest Period in sufficient time for the Trustee to give
notice to each Holder of such Carry-Over Amount as required in the next
succeeding sentence.  On the Interest Payment Date for an Interest Period with
respect to which such Carry-Over Amount has been calculated by the Trustee,
the Trustee shall give written notice to each Holder of the Carry-Over Amount
applicable to such Holder's Taxable LIBOR Rate Series 1998-1 Subordinate Note,
which written notice may accompany the payment of interest by check made to
each such Holder on such Interest Payment Date or otherwise shall be mailed on
such Interest Payment Date by first-class mail, postage prepaid, to each such
Holder at such Holder's address as it appears on the registration books
maintained by the Note Registrar.  Such notice shall state, in addition to
such Carry-Over Amount, that, unless and until a

                                     -116-
<PAGE>
 
Taxable LIBOR Rate Series 1998-1 Subordinate Note has been redeemed or has
been deemed no longer Outstanding under the Indenture (after which all accrued
Carry-Over Amount with respect to such Taxable LIBOR Rate Series 1998-1
Subordinate Note (and all accrued interest thereon) that remains unpaid shall
be cancelled and no Carry-Over Amount (or interest accrued thereon) shall be
paid with respect to such Taxable LIBOR Rate Series 1998-1 Subordinate Note),
(i) the Carry-Over Amount (and interest accrued thereon) shall be paid by the
Trustee on such Taxable LIBOR Rate Series 1998-1 Subordinate Note on the first
occurring Interest Payment Date for a subsequent Interest Period if and to the
extent that (a) the Eligible Carry-Over Make-Up Amount with respect to such
Interest Period is greater than zero, and (b) moneys are available pursuant to
the terms of the First Supplemental Indenture to pay such Carry-Over Amount
(and interest accrued thereon), and (ii) interest shall accrue on the
Carry-Over Amount at a per annum rate equal to the Taxable LIBOR Rate Series
1998-1 Subordinate Note LIBOR-Based Rate until such Carry-Over Amount is paid
in full or is cancelled.

     The Carry-Over Amount (and interest accrued thereon) for the Taxable
LIBOR Rate Series 1998-1 Subordinate Notes shall be paid by the Trustee on
Outstanding Taxable LIBOR Rate Series 1998-1 Subordinate Notes on the first
occurring Interest Payment Date for a subsequent Interest Period if and to the
extent that (a) the Eligible Carry-Over Make-Up Amount with respect to such
Interest Period is greater than zero, and (b) moneys in the Surplus Account
are available on such Interest Payment Date for transfer to the Interest
Account for such purpose in accordance with the second paragraph under
"Summary of the Indenture -- Funds and Accounts -- Surplus Account", after
taking into account all other amounts payable from the Surplus Fund in
accordance with such paragraph on such Interest Payment Date.  Any Carry-Over
Amount (and any interest accrued thereon) with respect to any Taxable LIBOR
Rate Series 1998-1 Subordinate Note which is unpaid as of an Interest Payment
Date, which Taxable LIBOR Rate Series 1998-1 Subordinate Note is to be called
for redemption or deemed no longer Outstanding under the First Supplemental
Indenture on such Interest Payment Date, shall be paid to the Holder thereof
on such Interest Payment Date to the extent that moneys are available therefor
in accordance with the provisions of the preceding clauses (a) and (b);
provided, however, that any Carry-Over Amount (and any interest accrued
thereon) which is not so paid on such Interest Payment Date shall be cancelled
with respect to such Taxable LIBOR Rate Series 1998-1 Subordinate Note on such
Interest Payment Date and shall not be paid on any succeeding Interest Payment
Date.  To the extent that any portion of the Carry-Over Amount (and any
interest accrued thereon) remains unpaid after payment of a portion thereof,
such unpaid portion shall be paid in whole or in part until fully paid by the
Trustee on the next occurring Interest Payment Date or Dates, as necessary,
for a subsequent Interest Period or Periods, if and to the extent that the
conditions in the first sentence of this paragraph are satisfied.  On any
Interest Payment Date on which the Trustee pays less than all of the
Carry-Over Amount (and any interest accrued thereon) with respect to a Taxable
LIBOR Rate Series 1998-1 Subordinate Note, the Trustee shall give written
notice in the manner set forth in the immediately preceding paragraph to the
Holder of such Taxable LIBOR Rate Series 1998-1 Subordinate Note of the
Carry-Over Amount remaining unpaid on such Taxable LIBOR Rate Series 1998-1
Subordinate Note.

     The Interest Payment Date on which any Carry-Over Amount (or any interest
accrued thereon) for the Taxable LIBOR Rate Series 1998-1 Subordinate Notes
shall be paid shall be determined by the Trustee in accordance with the
provisions of the immediately preceding paragraph, and the Trustee shall make
payment of the Carry-Over Amount (and any interest accrued thereon) in the
same manner as, and from the same Account from which, it pays interest on the
Taxable LIBOR Rate Series 1998-1 Subordinate Notes on an Interest Payment
Date.  ANY UNPAID CARRY-OVER AMOUNT, INCLUDING ANY ACCRUED AND UNPAID INTEREST
THEREON, ON A TAXABLE LIBOR RATE SERIES 1998-1 SUBORDINATE NOTE NOT PAYABLE ON
ANY REDEMPTION DATE WITH RESPECT TO SUCH TAXABLE LIBOR RATE SERIES 1998-1
SUBORDINATE NOTE WILL BE FORFEITED UPON THE REDEMPTION OR AT MATURITY OF SUCH
TAXABLE LIBOR RATE SERIES 1998-1 SUBORDINATE NOTE, OR ON SUCH EARLIER INTEREST
PAYMENT DATE, IF ANY, ON WHICH SUCH TAXABLE LIBOR RATE SERIES 1998-1
SUBORDINATE NOTE CEASES TO BE OUTSTANDING UNDER THE FIRST SUPPLEMENTAL
INDENTURE.  FITCH'S RATING ON THE TAXABLE LIBOR RATE SERIES 1998-1 SUBORDINATE
NOTES WILL NOT APPLY TO ANY CARRY-OVER AMOUNT THAT MAY ACCRUE ON THE TAXABLE
LIBOR RATE SERIES 1998-1 SUBORDINATE NOTES.

INTEREST LIMITED TO THE EXTENT PERMISSIBLE BY LAW

     In no event shall the cumulative amount of interest paid or payable on
the Taxable LIBOR Rate Series 1998-1 Subordinate Notes exceed the amount
permitted by applicable law.  If the applicable law is ever judicially
interpreted so as to render usurious any amount called for under the Taxable
LIBOR Rate Series 1998-1 Subordinate Notes or related documents or otherwise
contracted for, charged, reserved, taken or received in connection with the
Taxable LIBOR Rate Series 1998-1 Subordinate Notes, or if the call for
redemption or acceleration of the maturity of the Taxable LIBOR Rate Series
1998-1 Subordinate Notes results in payment to or receipt by the Holder or any
former Holder of the Taxable LIBOR Rate Series 1998-1 Subordinate Notes of any
interest in excess of that permitted by applicable law, then, notwithstanding
any provision of the Taxable LIBOR Rate Series 1998-1 Subordinate Notes or
related documents to the contrary, all excess amounts theretofore paid or
received with respect to the Taxable LIBOR Rate Series 1998-1 Subordinate
Notes shall be credited on the principal balance of the Taxable LIBOR Rate
Series 1998-1 Subordinate Notes (or, if the Taxable LIBOR Rate Series 1998-1
Subordinate Notes have been paid or would thereby be paid in full, refunded by
the recipient thereof), and the provisions of the Taxable LIBOR Rate Series
1998-1 Subordinate Notes and related documents shall automatically and

CALL FOR REDEMPTION AND PREPAYMENT OF THE TAXABLE LIBOR RATE SERIES 1998-1
SUBORDINATE NOTES

     The Taxable LIBOR Rate Series 1998-1 Subordinate Notes will be subject to
call for redemption and prepayment as described in this Prospectus under the
caption "Description of Series 1998-1 Notes -- Prepayment of Taxable LIBOR
Rate Series 1998-1 Notes" and "-- Special Call for Redemption -- Call for
Redemption of Series 1998-1 Notes Upon Reduction of Portfolio Balance."


                         WEIGHTED AVERAGE LIFE OF THE
                    TAXABLE LIBOR RATE SERIES 1998-1 NOTES

     THE FOLLOWING INFORMATION IS GIVEN SOLELY TO ILLUSTRATE THE EFFECT OF
PREPAYMENTS ON THE FINANCED STUDENT LOANS HELD IN THE SERIES 1998-1 TAXABLE
ACQUISITION ACCOUNT ON THE WEIGHTED AVERAGE LIFE OF THE TAXABLE LIBOR RATE
SERIES 1998-1 NOTES UNDER THE ASSUMPTIONS STATED BELOW AND IS NOT A PREDICTION
OF THE PREPAYMENT RATE THAT MIGHT ACTUALLY BE EXPERIENCED BY THE FINANCED
STUDENT LOANS HELD IN THE SERIES 1998-1 TAXABLE ACQUISITION ACCOUNT.

     Weighted average life refers to the average amount of time from the date
of issuance of a security until each dollar of principal of such security will
be repaid to the investor.  The weighted average life of the Taxable LIBOR
Rate Series 1998-1 Notes will be primarily a function of the rate at which
payments are made on the Financed Student Loans held in the Series 1998-1
Taxable Acquisition Account.  Payments on such Financed Student Loans may be
in the form of scheduled amortization of principal or prepayments (including,
for this purpose, reimbursements on defaults).

     The Constant Prepayment Rate prepayment model ("CPR") represents an
assumed constant rate of prepayment of Financed Student Loans held in the
Series 1998-1 Taxable Acquisition Account outstanding as of the beginning of
each month expressed as a per annum percentage.  There can be no assurance
that such Financed Student Loans will experience prepayments at a constant
prepayment rate or otherwise in the manner assumed by the prepayment model.

     The weighted average lives in the following table were determined
assuming that (i) scheduled payments of principal on the Financed Student
Loans held in the Series 1998-1 Taxable Acquisition Account are received in

                                     -118-
<PAGE>
 
a timely manner and prepayments are made at the percentages of the prepayment
model set forth in the table; (ii) the initial principal balance of the
Financed Student Loans held in the Series 1998-1 Taxable Acquisition Account
is $500,870,000; (iii) payments are made on the Taxable LIBOR Rate Series
1998-1 Notes on the 1st day of each month commencing March 1, 1998; and (iv)
the Taxable LIBOR Rate Series 1998-1 Notes are issued on February 19, 1998. No
representation is made that these assumptions will be correct, including the
assumption that the Financed Student Loans held in the Series 1998-1 Taxable
Acquisition Account will not experience delinquencies or unanticipated
losses.  See "Risk Factors -- Changes in the Assets of the Trust Estate,
Including Future Funding of Student Loans, Changing Characteristics of
Financed Student Loans, Financed Eligible Loans That are Not Made Under the
Federal Family Education Loan Program and Financed Student Loans That are Not
Eligible Loans in the Surplus Account," "-- Reduction in Amounts Available to
Pay Notes Due to the Variability of Actual Cash Flows and Due to the Inability
of Guarantee Agencies to Make Guarantee Payments," "-- Holders of Series
1998-1 Notes Which are Prepaid or Called for Redemption Due to Accelerated
Payments with respect to Financed Student Loans May Have to Reinvest Amounts
Received From Prepayments or Calls for Redemption at a Lower Rate of Return,"
and "-- The Average Life of the Series 1998-1 Notes May Be Lengthened As a
Result of Extension of Payments on the Financed Student Loans."

     In making an investment decision with respect to the Taxable LIBOR Rate
Series 1998-1 Notes, investors should consider a variety of possible
prepayment scenarios, including the limited scenarios described in the table
below.

            AUCTION OF THE AUCTION RATE SERIES 1998-1 SENIOR NOTES

     If not otherwise defined below, capitalized terms used below will have
the meanings given such terms under "Glossary of Certain Defined Terms".
Unless otherwise noted or the context otherwise requires, the following
description of Auctions and related procedures is applicable separately to
each series of the Auction Rate Series 1998-1 Senior Notes.

SUMMARY OF AUCTION PROCEDURES

     The following summarizes certain procedures that will be used in
determining the interest rates on the Auction Rate Series 1998-1 Senior
Notes.  Immediately following this summary is a more detailed description of
these procedures.  Prospective investors in the Auction Rate Series 1998-1
Senior Notes should read carefully the following summary, along with the more
detailed description.

     The interest rate on each series of Auction Rate Series 1998-1 Senior
Notes will be determined periodically (generally, for periods ranging from 7
days to one year, and initially 28 days, in the case of the Taxable Auction
Rate Series 1998-1 Senior Notes, or 35 days, in the case of Tax Exempt Auction
Rate Series 1998-1 Senior Notes) by means of a "Dutch auction."  In this Dutch
auction, investors and potential investors submit orders through an eligible
Broker-Dealer as to the principal amount of Auction Rate Series 1998-1 Senior
Notes such investors wish

                                     -119-
<PAGE>
 
to buy, hold or sell at various interest rates.  The Broker-Dealers submit
their clients' orders to the Auction Agent, who processes all orders submitted
by all eligible Broker-Dealers and determines the interest rate for the
upcoming interest period.  The Broker-Dealers are notified by the Auction
Agent of the interest rate for the upcoming interest period and are provided
with settlement instructions relating to purchases and sales of Auction Rate
Series 1998-1 Senior Notes.

     In the auction procedure, the following orders may be submitted:

     (i)   "Bid Orders" - the minimum interest rate that a current investor is
           willing to accept in order to continue to hold some or all of its
           Auction Rate Series 1998-1 Senior Notes for the upcoming interest
           period;

     (ii)  "Sell Orders" - an order by a current investor to sell a specified
           principal amount of Auction Rate Series 1998-1 Senior Notes,
           regardless of the upcoming interest rate;

     (iii) "Hold Order" - an order by a current investor to hold a specified
           principal amount of Auction Rate Series 1998-1 Senior Notes,
           regardless of the upcoming interest rate; and

     (iv)  "Potential Bid Orders" - the minimum interest rate that a potential
           investor (or a current investor wishing to purchase additional
           Auction Rate Series 1998-1 Senior Notes) is willing to accept in
           order to buy a specified principal amount of Auction Rate Series
           1998-1 Senior Notes.

     If an existing investor does not submit orders with respect to all its
Auction Rate Series 1998-1 Senior Notes of a particular series, the investor
will be deemed to have submitted a Hold Order at the new interest rate for
that portion of such series for which no order was received.

     In connection with each Auction, Auction Rate Series 1998-1 Senior Notes
will be purchased and sold between investors and potential investors at a
price equal to their then-outstanding principal balance (i.e., par) plus any
accrued interest.  The following example helps illustrate how the
above-described procedures are used in determining the interest rate on the
Auction Rate Series 1998-1 Senior Notes.

     (a)     Assumptions:

          1.     Denominations (Units)          = $100,000
          2.     Interest Period                = 28 days
          3.     Principal Amount Outstanding   = $50 Million (500 Units)

</TABLE>

(W) Winning Order     (L) Losing Order


     Order #10 is the order that clears the market of all available units.
All winning orders are awarded the winning rate (in this case, 3.12%) as the
interest rate for the next Interest Period, when another Auction will be
held.  Multiple orders at the winning rate are allocated units on a pro rata
basis.  Notwithstanding the foregoing, in no event will the interest rate
exceed (i) in the case of the Tax Exempt Auction Rate Series 1998-1 Senior
Notes, the Maximum Auction Rate, or (ii) in the case of the Taxable Auction
Rate Series 1998-1 Senior Notes, the lesser of the Net Loan Rate or the
Maximum Auction Rate.

     The above example assumes that a successful Auction has occurred (i.e.,
all Sell Orders and all Bid Orders below the new interest rate were
fulfilled).  In certain circumstances, there may be insufficient Potential Bid
Orders to purchase all the Auction Rate Series 1998-1 Senior Notes offered for
sale.  In such circumstances, the interest rate for the upcoming Interest
Period will equal (i) in the case of the Tax Exempt Auction Rate Series 1998-1
Senior Notes, the Maximum Auction Rate, or (ii) in the case of the Taxable
Auction Rate Series 1998-1 Senior Notes, the lesser of the Net Loan Rate and
the Maximum Auction Rate.  Also, if all the Auction Rate Series 1998-1 Senior

                                     -121-
<PAGE>
 
Notes are subject to Hold Orders (i.e., each Holder of Auction Rate Series
1998-1 Senior Notes wishes to continue holding its Auction Rate Series 1998-1
Senior Notes, regardless of the interest rate), the interest rate for the
upcoming Interest Period will equal (i) in the case of the Tax Exempt Auction
Rate Series 1998-1 Senior Notes, the lesser of the Maximum Auction Rate and
the All Hold Rate, or (ii) in the case of the Taxable Auction Rate Series
1998-1 Senior Notes, the least of the Maximum Auction Rate, the Net Loan Rate
and the All Hold Rate.

     Neither the Original Issuer nor the Corporation will be involved in
directing the Auction Agent in conducting an Auction.

     As stated above, the foregoing is only a summary of the Auction
Procedures.  The remainder of this Section is a more detailed description of
these procedures.

AUCTION PARTICIPANTS

     Existing Holders and Potential Holders

     Participants in each Auction will include:  (1) "Existing Holders", which

     By purchasing the Auction Rate Series 1998-1 Senior Notes, whether in an

to sell, transfer or otherwise dispose of the Auction Rate Series 1998-1
Senior Notes only pursuant to a Bid (as defined below) or a Sell Order (as
defined below) in an Auction, or otherwise through a Broker-Dealer, provided
that in the case of all transfers other than those pursuant to an Auction, the
Existing Holder of the Auction Rate Series 1998-1 Senior Notes so transferred,
its Participant or Broker-Dealer advises the Auction Agent of such transfer;
(iv) that a Sell Order placed by an Existing Holder will constitute an
irrevocable offer to sell the principal amount of the Auction Rate Series
1998-1 Senior Notes specified in such Sell Order; (v) that a Bid placed by an
Existing Holder will constitute an irrevocable offer to sell the principal
amount, or a lesser principal amount, of the Auction Rate Series 1998-1 Senior
Notes specified in such Bid if the rate specified in such Bid is greater than,
or in some cases equal to, the Auction Rate Series 1998-1 Senior Note Interest
Rate, determined as described herein; and (vi) that a Bid placed by a
Potential Holder will constitute an irrevocable offer to purchase the amount,
or a lesser principal amount, of the Auction Rate Series 1998-1 Senior Notes
specified in such Bid if the rate specified in such Bid is, respectively, less
than or equal to the Auction Rate Series 1998-1 Senior Note Interest Rate,
determined as described herein.

     The principal amount of the Auction Rate Series 1998-1 Senior Notes
purchased or sold may be subject to proration procedures on the Auction Date.
Each purchase or sale of the Auction Rate Series 1998-1 Senior Notes on the
Auction Date will be made for settlement on the first day of the Interest
Period immediately following such Auction Date at a price equal to 100% of the
principal amount thereof plus, unless such day is an Interest Payment Date,
accrued interest thereon to but not including such day.  The Auction Agent is
entitled to rely upon the terms of any Order submitted to it by a
Broker-Dealer.

     Auction Agent

     Bankers Trust Company is appointed in the First Supplemental Indenture as
the initial Auction Agent to serve as agent for the Corporation in connection
with Auctions with respect to Tax Exempt Auction Rate Series 1998-1 Senior
Notes.  The Trustee and the Corporation will enter into the initial Auction
Agent Agreement relating to Tax Exempt Auction Rate Series 1998-1 Senior Notes
with Bankers Trust Company, as the initial Auction Agent.  Bankers Trust
Company also is appointed in the First Supplemental Indenture as the initial

Agreement relating to Taxable Auction Rate Series 1998-1 Senior Notes with
Bankers Trust Company, as the initial Auction Agent.  Any substitute Auction
Agent shall be (i) a bank, national banking association or trust company duly

Agent may at any time resign and be discharged of the duties and obligations
created by the First Supplemental Indenture and the Auction Agent Agreement by
giving at least 90 days' notice to the Trustee and the Corporation.  The
Auction Agent may be removed at any time by the Trustee upon the written
direction of an Authorized Officer of the Corporation or the Holders of
66-2/3% of the aggregate principal amount of the Auction Rate Series 1998-1
Senior Notes of all series then Outstanding, and, if by such Holders, by an
instrument signed by such Holders or their attorneys and filed with the
Auction Agent, the Corporation and the Trustee upon at least 90 days' notice.
Neither resignation nor removal of the Auction Agent pursuant to the preceding
two sentences shall be effective unless and until a substitute Auction Agent
has been appointed and has accepted such appointment.  If required by the
Corporation, a substitute Auction Agent Agreement shall be entered into with a
substitute Auction Agent.  Notwithstanding the foregoing, the Auction Agent
may terminate the Auction Agent Agreement if, within 25 days after notifying
the Trustee and the Corporation in writing that it has not received payment of
any Auction Agent fee due it in accordance with the terms of the Auction Agent
Agreement, the Auction Agent does not receive such payment.

     If the Auction Agent shall resign or be removed or be dissolved, or if
the property or affairs of the Auction Agent shall be taken under the control
of any state or federal court or administrative body because of bankruptcy or
insolvency, or for any other reason, the Trustee, at the direction of an
Authorized Officer of the Corporation, shall use its best efforts to appoint a
substitute Auction Agent.

      The Auction Agent is acting as agent for the Corporation in connection
with Auctions.  In the absence of bad faith, negligent failure to act or
negligence on its part, the Auction Agent shall not be liable for any action
taken, suffered or omitted or any error of judgment made by it in the
performance of its duties under the Auction Agent Agreement and shall not be
liable for any error of judgment made in good faith unless the Auction Agent
shall have been negligent in ascertaining (or failing to ascertain) the
pertinent facts.

     The Corporation will pay the Auction Agent the Auction Agent fee on each
Interest Payment Date and will reimburse the Auction Agent upon its request
for all reasonable expenses, disbursements and advances incurred or made by
the Auction Agent in accordance with any provision of the Auction Agent
Agreement or the Broker-Dealer Agreements (including the reasonable
compensation and the expenses and disbursements of its agents and counsel).
Such amounts are payable from the Administration Fund.  The Corporation will
indemnify and hold harmless the Auction Agent for and against any loss,
liability or expense incurred without negligence or bad faith on the Auction
Agent's part, arising out of or in connection with the acceptance or
administration of its agency under the Auction Agent Agreement and the
Broker-Dealer Agreements, including the reasonable costs and expenses
(including the reasonable fees and expenses of its counsel) of defending
itself against any such claim or liability in connection with its exercise or
performance of any of its respective duties thereunder and of enforcing this
indemnification provision; provided that the Corporation will not indemnify
the Auction Agent as described in this paragraph for any fees and

                                     -123-
<PAGE>
 
expenses incurred by the Auction Agent in the normal course of performing its
duties under the Auction Agent Agreement and under the Broker-Dealer
Agreements, such fees and expenses being payable as described above.

     Broker-Dealer

     Existing Holders and Potential Holders may participate in Auctions only
by submitting orders (in the manner described below) through a Broker-Dealer,
including Smith Barney Inc., which initially will be the only Broker-Dealer
for each of the Tax Exempt Auction Rate Series 1998-1 Senior Notes and the

by the Auction Agent from monies received from the Corporation, on each
Interest Payment Date.  Such Broker-Dealer fee is payable from the
Administration Fund as provided in the First Supplemental Indenture.

     Market Agent

     Although Smith Barney Inc. is acting as an Underwriter in connection with
the offering, in connection with the Auction Rate Series 1998-1 Senior Notes,

any obligation or relationship of agency or trust for or with any of the

AUCTION PROCEDURES

     General

     Pursuant to the First Supplemental Indenture, Auctions to establish the
Auction Rate for the Auction Rate Series 1998-1 Senior Notes will be held on
each Auction Date, except as described under Appendices Terms of the Tax
Exempt Auction Rate Series 1998-1 Senior Notes -- Interest Rate on the Tax
Exempt Auction Rate Series 1998-1 Senior Notes" and "Terms of the Taxable
Auction Rate Series 1998-1 Senior Notes -- Interest Rate on the Taxable
Auction Rate Series 1998-1 Senior Notes", respectively, by application of the
Auction Procedures described herein.  Such procedures are to be applicable
separately to each series of Auction Rate Series 1998-1 Senior Notes.
"Auction Date" means, initially, with respect to the Series 1998-1A Notes,
March 25, 1998, with respect to the Series 1998-1B Notes, April 1, 1998, with
respect to the Series 1998-1C Notes, April 8, 1998, with respect to the Series
1998-1D Notes, April 15, 1998, with respect to the Series 1998-1E Notes, April
22, 1998, with respect to the Series 1998-1G Notes, March 23, 1998, and with
respect to the Series 1998-1H Notes, March 30, 1998, and, thereafter, with
respect to each such series of Auction Rate Series 1998-1 Senior Notes, the
Business Day immediately preceding the first day of each related Auction
Period, other than:  (i) any Interest Period commencing after the ownership of
such series is no longer maintained in Book-Entry Form; (ii) any Interest
Period commencing after the occurrence and during the continuance of a Payment
Default; or (iii) any Auction Period commencing less than two Business Days
after the cure of a Payment Default.  Notwithstanding the foregoing, the
Auction Date for one or more Auction Periods may be changed as described below
under "Changes in Auction Terms".

     The Auction Agent will calculate the Maximum Auction Rate and the All
Hold Rate on each Auction Date.  The Corporation (or the Servicer on behalf of
the Corporation) will calculate the Net Loan Rate monthly.  If the ownership
of the Auction Rate Series 1998-1 Senior Notes is no longer maintained in
Book-Entry Form, the Trustee will calculate the Maximum Auction Rate on the
Business Day immediately preceding the first day of each Interest Period
commencing after delivery of the Auction Rate Series 1998-1 Senior Notes.  If
a Payment Default has occurred, the Trustee will calculate the Non-Payment
Rate on the Interest Rate Determination Date for (i) each

                                     -124-
<PAGE>
 
Interest Period commencing after the occurrence and during the continuance of
such Payment Default and (ii) any Interest Period commencing less than two
Business Days after the cure of any Payment Default.  The Auction Agent shall
determine (i) with respect to the Taxable Auction Rate Series 1998-1 Senior
Notes, the One-Month LIBOR or the Three-Month LIBOR, as applicable, and (ii)
with respect to the Tax Exempt Auction Rate Series 1998-1 Senior Notes, the
After-Tax Equivalent, the "AA" Composite Commercial Paper Rate and the
Applicable Percentage for each Interest Period other than the Initial Interest
Period. If the ownership of the Auction Rate Series 1998-1 Senior Notes is no
longer maintained in Book-Entry Form, or if a Payment Default has occurred,
then the Trustee shall determine the One-Month LIBOR or the Three-Month LIBOR,
as applicable, the After-Tax Equivalent, the "AA" Composite Commercial Paper
Rate and the Applicable Percentage for each such Interest Period.  The
determination by the Trustee or the Auction Agent, as the case may be, of the
One-Month LIBOR or the Three-Month LIBOR, as applicable, the After-Tax
Equivalent, the "AA" Composite Commercial Paper Rate and the Applicable
Percentage shall (in the absence of manifest error) be final and binding upon
all parties.  The Auction Agent shall promptly advise the Trustee of the
One-Month LIBOR or the Three-Month LIBOR, as applicable, the After-Tax
Equivalent, the "AA" Composite Commercial Paper Rate and the Applicable
Percentage upon its determination thereof.  The Market Agent shall calculate
the Index (if the Index is other than the PSA Index) with respect to the Tax
Exempt Auction Rate Series 1998-1 Senior Notes on each Interest Rate
Determination Date and shall notify the Trustee and the Auction Agent of the
Index on each Interest Rate Determination Date.  The determination by the
Market Agent of the Index shall (in the absence of manifest error) be final
and binding upon all parties.

     If the Federal Reserve Bank of New York does not make available its
30-day commercial paper rate for purposes of determining the "AA" Composite
Commercial Paper Rate, the Auction Agent shall notify the Trustee of such fact
and the Trustee shall thereupon request that an Authorized Officer of the
Corporation promptly appoint at least two Commercial Paper Dealers (in
addition to Smith Barney Inc.) to provide commercial paper quotes for purposes
of determining the "AA" Composite Commercial Paper Rate.  Pending appointment
of both such additional Commercial Paper Dealers, Smith Barney Inc. and any
other Commercial Paper Dealer appointed and serving as such shall provide the
required quotations and such quotations shall be used for purposes of the
First Supplemental Indenture.  Smith Barney Inc. has been appointed as a
Commercial Paper Dealer to provide commercial paper quotes for purposes of
determining the "AA" Composite Commercial Paper Rate as aforesaid.

     Submission of Orders

     So long as the ownership of a series of Auction Rate Series 1998-1 Senior
Notes is maintained in Book-Entry Form, an Existing Holder may sell, transfer
or otherwise dispose of Auction Rate Series 1998-1 Senior Notes of such series
only pursuant to a Bid or Sell Order (as hereinafter defined) placed in an
Auction or otherwise sell, transfer or dispose of such series through a
Broker-Dealer, provided that, in the case of all transfers other than pursuant
to Auctions, such Existing Holder, its Broker-Dealer or its Participant
advises the Auction Agent of such transfer. Auctions shall be conducted on
each Auction Date, if there is an Auction Agent on such Auction Date, in the
following manner:

     Prior to the Submission Deadline (defined as 1:00 p.m., New York City
time, on any Auction Date or such other time on any Auction Date by which
Broker-Dealers are required to submit Orders to the Auction Agent as specified
by the Auction Agent from time to time) on each Auction Date:

          (a)     each Existing Holder of Auction Rate Series 1998-1 Senior
     Notes may submit to a Broker-Dealer by telephone or otherwise information
     as to: (i) the principal amount of Outstanding Auction Rate Series 1998-1
     Senior Notes, if any, held by such Existing Holder which such Existing
     Holder desires to continue to hold without regard to the Auction Rate
     Series 1998-1 Senior Note Interest Rate for the next succeeding Auction
     Period (a "Hold Order"); (ii) the principal amount of Outstanding Auction
     Rate Series 1998-1 Senior Notes, if any, which such Existing

                                     -125-
<PAGE>
 
     Holder offers to sell if the Auction Rate Series 1998-1 Senior Note
     Interest Rate for the next succeeding Auction Period will be less than
     the rate per annum specified by such Existing Holder (a "Bid"); and/or
     (iii) the principal amount of Outstanding Auction Rate Series 1998-1
     Senior Notes, if any, held by such Existing Holder which such Existing
     Holder offers to sell without regard to the Auction Rate Series 1998-1
     Senior Note Interest Rate for the next succeeding Auction Period (a "Sell
     Order"); and

          (b)     one or more Broker-Dealers may contact Potential Holders to
     determine the principal amount of Auction Rate Series 1998-1 Senior Notes
     which each such Potential Holder offers to purchase, if the Auction Rate
     Series 1998-1 Senior Note Interest Rate for the next succeeding Auction
     Period will not be less than the rate per annum specified by such
     Potential Holder (also a "Bid").

     Each Hold Order, Bid and Sell Order will be an "Order".  Each Existing
Holder and each Potential Holder placing an Order is referred to as a
"Bidder".

     Subject to the provisions of the First Supplemental Indenture described
below under "Validity of Orders", a Bid by an Existing Holder will constitute
an irrevocable offer to sell:  (i) the principal amount of Outstanding Auction
Rate Series 1998-1 Senior Notes specified in such Bid if the Auction Rate
Series 1998-1 Senior Note Interest Rate will be less than the rate specified
in such Bid, (ii) such principal amount or a lesser principal amount of
Outstanding Auction Rate Series 1998-1 Senior Notes to be determined as
described below in "Acceptance and Rejection of Orders", if the Auction Rate
Series 1998-1 Senior Note Interest Rate will be equal to the rate specified in
such Bid, or (iii) such principal amount or a lesser principal amount of
Outstanding Auction Rate Series 1998-1 Senior Notes to be determined as
described below under "Acceptance and Rejection of Orders", if the rate
specified therein will be higher than the Auction Rate Series 1998-1 Senior
Note Interest Rate and Sufficient Bids (as defined below) have not been made.

     Subject to the provisions of the First Supplemental Indenture described
below under "Validity of Orders", a Sell Order by an Existing Holder will
constitute an irrevocable offer to sell:  (i) the principal amount of
Outstanding Auction Rate Series 1998-1 Senior Notes specified in such Sell
Order or (ii) such principal amount or a lesser principal amount of
Outstanding Auction Rate Series 1998-1 Senior Notes as described below under
"Acceptance and Rejection of Orders", if Sufficient Bids have not been made.

     Subject to the provisions of the First Supplemental Indenture described
below under "Validity of Orders", a Bid by a Potential Holder will constitute
an irrevocable offer to purchase:  (i) the principal amount of Outstanding
Auction Rate Series 1998-1 Senior Notes specified in such Bid if the Auction
Rate Series 1998-1 Senior Note Interest Rate will be higher than the rate
specified in such Bid or (ii) such principal amount or a lesser principal
amount of Outstanding Auction Rate Series 1998-1 Senior Notes as described
below in "Acceptance and Rejection of Orders", if the Auction Rate Series
1998-1 Senior Note Interest Rate is equal to the rate specified in such Bid.

     Each Broker-Dealer will submit in writing to the Auction Agent prior to
the Submission Deadline on each Auction Date all Orders obtained by such
Broker-Dealer and will specify with respect to each such Order:  (i) the name
of the Bidder placing such Order; (ii) the aggregate principal amount of
Auction Rate Series 1998-1 Senior Notes that are the subject of such Order;
(iii) to the extent that such Bidder is an Existing Holder:  (a) the principal
amount of Auction Rate Series 1998-1 Senior Notes, if any, subject to any Hold
Order placed by such Existing Holder; (b) the principal amount of Auction Rate
Series 1998-1 Senior Notes, if any, subject to any Bid placed by such Existing
Holder and the rate specified in such Bid; and (c) the principal amount of
Auction Rate Series 1998-1 Senior Notes, if any, subject to any Sell Order
placed by such Existing Holder; and (iv) to the extent such Bidder is a
Potential Holder, the rate specified in such Potential Holder's Bid.

     If any rate specified in any Bid contains more than three figures to the
right of the decimal point, the Auction Agent will round such rate up to the
next highest .001%.

<PAGE>
 
     If an Order or Orders covering all Outstanding Auction Rate Series 1998-1
Senior Notes held by any Existing Holder are not submitted to the Auction
Agent prior to the Submission Deadline, the Auction Agent will deem a Hold
Order to have been submitted on behalf of such Existing Holder covering the
principal amount of Outstanding Auction Rate Series 1998-1 Senior Notes held
by such Existing Holder and not subject to an Order submitted to the Auction
Agent.

     Neither the Corporation, the Trustee nor the Auction Agent will be
responsible for any failure of a Broker-Dealer to submit an Order to the
Auction Agent on behalf of any Existing Holder or Potential Holder.

     An Existing Holder may submit multiple Orders, of different types and
specifying different rates, in an Auction with respect to Auction Rate Series
1998-1 Senior Notes then held by such Existing Holder.  An Existing Holder
that offers to purchase additional Auction Rate Series 1998-1 Senior Notes is,
for purposes of such offer, treated as a Potential Holder.

     Any Bid specifying a rate higher than the applicable Maximum Auction Rate
will (i) be treated as a Sell Order if submitted by an Existing Holder and
(ii) not be accepted if submitted by a Potential Holder.

     Validity of Orders

     If any Existing Holder submits through a Broker-Dealer to the Auction
Agent one or more Orders covering in the aggregate more than the principal
amount of Outstanding Auction Rate Series 1998-1 Senior Notes held by such
Existing Holder, such Orders will be considered valid as follows and in the
order of priority described below.

          Hold Orders.  All Hold Orders will be considered valid, but only up
     to the aggregate principal amount of Outstanding Auction Rate Series
     1998-1 Senior Notes held by such Existing Holder, and if the aggregate
     principal amount of Auction Rate Series 1998-1 Senior Notes subject to
     such Hold Orders exceeds the aggregate principal amount of Auction Rate
     Series 1998-1 Senior Notes held by such Existing Holder, the aggregate
     principal amount of Auction Rate Series 1998-1 Senior Notes subject to
     each such Hold Order will be reduced pro rata so that the aggregate
     principal amount of Auction Rate Series 1998-1 Senior Notes subject to
     all such Hold Orders equals the aggregate principal amount of Outstanding
     Auction Rate Series 1998-1 Senior Notes held by such Existing Holder.

          Bids.  Any Bid will be considered valid up to an amount equal to the
     excess of the principal amount of Outstanding Auction Rate Series 1998-1
     Senior Notes held by such Existing Holder over the aggregate principal
     amount of Auction Rate Series 1998-1 Senior Notes subject to any Hold
     Orders referred to above.  Subject to the preceding sentence, if multiple
     Bids with the same rate are submitted on behalf of such Existing Holder
     and the aggregate principal amount of Outstanding Auction Rate Series
     1998-1 Senior Notes subject to such Bids is greater than such excess,
     such Bids will be considered valid up to an amount equal to such excess.
     Subject to the two preceding sentences, if more than one Bid with
     different rates is submitted on behalf of such Existing Holder, such Bids
     will be considered valid first in the ascending order of their respective
     rates until the highest rate is reached at which such excess exists and
     then at such rate up to the amount of such excess.  In any event, the
     aggregate principal amount of Outstanding Auction Rate Series 1998-1
     Senior Notes, if any, subject to Bids not valid under the provisions
     described above will be treated as the subject of a Bid by a Potential
     Holder at the rate therein specified.

          Sell Orders.  All Sell Orders will be considered valid up to an
     amount equal to the excess of the principal amount of Outstanding Auction
     Rate Series 1998-1 Senior Notes held by such Existing Holder over the
     aggregate principal amount of Auction Rate Series 1998-1 Senior Notes
     subject to valid Hold Orders and valid Bids as referred to above.

                                     -127-
<PAGE>
 
     If more than one Bid for Auction Rate Series 1998-1 Senior Notes is
submitted on behalf of any Potential Holder, each Bid submitted will be a
separate Bid with the rate and principal amount therein specified.  Any Bid or
Sell Order submitted by an Existing Holder covering an aggregate principal
amount of Auction Rate Series 1998-1 Senior Notes not equal to an Authorized
Denomination will be rejected and will be deemed a Hold Order.  Any Bid
submitted by a Potential Holder covering an aggregate principal amount of
Auction Rate Series 1998-1 Senior Notes not equal to an Authorized
Denomination will be rejected. Any Order submitted in an Auction by a
Broker-Dealer to the Auction Agent prior to the Submission Deadline on any
Auction Date will be irrevocable.

     A Hold Order, a Bid or a Sell Order that has been determined valid
pursuant to the procedures described above is referred to as a "Submitted Hold
Order", a "Submitted Bid" and a "Submitted Sell Order", respectively (collective
ly, "Submitted Orders").

     Determination of Sufficient Bids and Bid Auction Rate

     Not earlier than the Submission Deadline on each Auction Date, the
Auction Agent will assemble all valid Submitted Orders and will determine:

          (a)     the excess of the total principal amount of Outstanding
     Auction Rate Series 1998-1 Senior Notes over the sum of the aggregate
     principal amount of Outstanding Auction Rate Series 1998-1 Senior Notes
     subject to Submitted Hold Orders (such excess being hereinafter referred
     to as the "Available Auction Rate Series 1998-1 Senior Notes"); and

          (b)     from such Submitted Orders whether the aggregate principal
     amount of Outstanding Auction Rate Series 1998-1 Senior Notes subject to
     Submitted Bids by Potential Holders specifying one or more rates equal to
     or lower than the Maximum Auction Rate exceeds or is equal to the sum of
     (i) the aggregate principal amount of Outstanding Auction Rate Series
     1998-1 Senior Notes subject to Submitted Bids by Existing Holders
     specifying one or more rates higher than the Maximum Auction Rate and
     (ii) the aggregate principal amount of Outstanding Auction Rate Series
     1998-1 Senior Notes subject to Submitted Sell Orders (in the event such
     excess or such equality exists other than because all of the Outstanding
     Auction Rate Series 1998-1 Senior Notes are subject to Submitted Hold
     Orders, such Submitted Bids by Potential Holders above will be
     hereinafter referred to collectively as "Sufficient Bids"); and

          (c)     if Sufficient Bids exist, the "Bid Auction Rate", which will
     be the lowest rate specified in such Submitted Bids such that if:

               (i)          each such Submitted Bid from Existing Holders
          specifying such lowest rate and all other Submitted Bids from
          Existing Holders specifying lower rates were rejected (thus
          entitling such Existing Holders to continue to hold the principal
          amount of Auction Rate Series 1998-1 Senior Notes subject to such
          Submitted Bids); and

               (ii)         each such Submitted Bid from Potential Holders
          specifying such lowest rate and all other Submitted Bids from
          Potential Holders specifying lower rates, were accepted,

     the result would be that such Existing Holders described in subparagraph
     (c)(i) above would continue to hold an aggregate principal amount of
     Outstanding Auction Rate Series 1998-1 Senior Notes which, when added to
     the aggregate principal amount of Outstanding Auction Rate Series 1998-1
     Senior Notes to be purchased by such Potential Holders described in
     subparagraph (c)(ii) above would equal not less than the Available
     Auction Rate Series 1998-1, Senior Notes.

     Determination of Auction Rate and Auction Rate Series 1998-1 Senior Note
Interest Rate; Notice

     Promptly after the Auction Agent has made the determinations described
above, the Auction Agent is to advise the Trustee of the Maximum Auction Rate
and the All Hold Rate and the components thereof on the Auction Date and,
based on such determinations and the Net Loan Rate determined by the
Corporation or the Servicer, the Auction Rate for the next succeeding Interest
Period as follows:

          (a)     if Sufficient Bids exist, that the Auction Rate for the next
     succeeding Interest Period will be equal to the Bid Auction Rate so
     determined;

          (b)     if Sufficient Bids do not exist (other than because all of
     the Outstanding Auction Rate Series 1998-1 Senior Notes are subject to
     Submitted Hold Orders), that the Auction Rate for the next succeeding
     Interest Period will be equal to the Maximum Auction Rate; or

          (c)     if all Outstanding Auction Rate Series 1998-1 Senior Notes
     are subject to Submitted Hold Orders, that the Auction Rate for the next
     succeeding Interest Period will be equal to the All Hold Rate.

     Promptly after the Auction Agent has determined the Auction Rate, the
Auction Agent will determine and advise the Trustee of the Auction Rate Series
1998-1 Senior Note Interest Rate, which rate will be (i) in the case of the
Taxable Auction Rate Series 1998-1 Senior Notes, the lesser of the Auction
Rate and the Net Loan Rate, and (ii) in the case of the Tax Exempt Auction
Rate Series 1998-1 Senior Notes, the Auction Rate.  In no event shall the
Auction Rate Series 1998-1 Senior Note Interest Rate exceed the Auction Rate
Series 1998-1 Senior Note Interest Rate Limitation, which, in the case of the
Taxable Auction Rate Series 1998-1 Senior Notes, will be 18% per annum, and,
in the case of the Tax Exempt Auction Rate Series 1998-1 Senior Notes, will be
14% per annum.

     Acceptance and Rejection of Orders

     Existing Holders will continue to hold the principal amount of Auction
Rate Series 1998-1 Senior Notes that are subject to Submitted Hold Orders.  If
Sufficient Bids, as described above under "Determination of Sufficient Bids
and Bid Auction Rate", have been received by the Auction Agent (and if, in the
case of the Taxable Auction Rate Series 1998-1 Senior Notes, the Net Loan Rate
is equal to or greater than the Bid Auction Rate), the Bid Auction Rate will
be the Auction Rate Series 1998-1 Senior Note Interest Rate, and Submitted
Bids and Submitted Sell Orders will be accepted or rejected and the Auction
Agent will take such other action as provided in the First Supplemental
Indenture and described below under "Sufficient Bids".

     If the Auction Rate is (or, in the case of the Taxable Auction Rate
Series 1998-1 Senior Notes, if the Auction Rate and the Net Loan Rate are
both) greater than the Auction Rate Series 1998-1 Senior Note Interest Rate
Limitation, the Auction Rate Series 1998-1 Senior Note Interest Rate will be
equal to the Auction Rate Series 1998-1 Senior Note Interest Rate Limitation.
If, in the case of the Taxable Auction Rate Series 1998-1 Senior Notes, the
Net Loan Rate is less than the Auction Rate, the Auction Rate Series 1998-1
Senior Note Interest Rate for such Notes will be the Net Loan Rate.  If the
Auction Agent has not received Sufficient Bids as described above under
"Determination of Sufficient Bids and Bid Auction Rate" (other than because
all of the Outstanding Auction Rate Series 1998-1 Senior Notes are subject to
Submitted Hold Orders), the Auction Rate Series 1998-1 Senior Note Interest
Rate will be (i) in the case of the Taxable Auction Rate Series 1998-1 Senior
Notes, the lesser of the Maximum Auction Rate and the Net Loan Rate, and (ii)
in the case of the Tax Exempt Auction Rate Series 1998-1 Senior Notes, the
Maximum Auction Rate.  In any of the cases described above in this paragraph,
Submitted Orders will be accepted or rejected and the Auction Agent will take
such other action as described below under "Insufficient Bids".

          Sufficient Bids.  If Sufficient Bids have been made (and, in the
     case of the Taxable Auction Rate Series 1998-1 Senior Notes, the Net Loan
     Rate is equal to or greater than the Bid

                                     -129-
<PAGE>
 
     Auction Rate) (in which case the Auction Rate Series 1998-1 Senior Note
     Interest Rate shall be the Bid Auction Rate), all Submitted Sell Orders
     will be accepted and, subject to the denomination requirements described
     below, Submitted Bids will be accepted or rejected as follows in the
     following order of priority and all other Submitted Bids will be
     rejected:

               (a)     Existing Holders' Submitted Bids specifying any rate
          that is higher than the Auction Rate Series 1998-1 Senior Note
          Interest Rate will be accepted, thus requiring each such Existing
          Holder to sell the aggregate principal amount of Auction Rate Series
          1998-1 Senior Notes subject to such Submitted Bids;

               (b)     Existing Holders' Submitted Bids specifying any rate
          that is lower than the Auction Rate Series 1998-1 Senior Note
          Interest Rate will be rejected, thus entitling each such Existing
          Holder to continue to hold the aggregate principal amount of Auction
          Rate Series 1998-1 Senior Notes subject to such Submitted Bids;

               (c)     Potential Holders' Submitted Bids specifying any rate
          that is lower than the Auction Rate Series 1998-1 Senior Note
          Interest Rate will be accepted;

               (d)     Each Existing Holder's Submitted Bid specifying a rate
          that is equal to the Auction Rate Series 1998-1 Senior Note Interest
          Rate will be rejected, thus entitling such Existing Holder to
          continue to hold the aggregate principal amount of Auction Rate
          Series 1998-1 Senior Notes subject to such Submitted Bid, unless the
          aggregate principal amount of Auction Rate Series 1998-1 Senior
          Notes subject to such Submitted Bids will be greater than the
          principal amount of Auction Rate Series 1998-1 Senior Notes (the
          "remaining principal amount") equal to the excess of the Available
          Auction Rate Series 1998-1 Senior Notes over the aggregate principal
          amount of Auction Rate Series 1998-1 Senior Notes subject to
          Submitted Bids described in subparagraphs (b) and (c) above, in
          which event such Submitted Bid of such Existing Holder will be
          rejected in part and such Existing Holder will be entitled to
          continue to hold the principal amount of Auction Rate Series 1998-1
          Senior Notes subject to such Submitted Bid, but only in an amount
          equal to the aggregate principal amount of Auction Rate Series
          1998-1 Senior Notes obtained by multiplying the remaining principal
          amount by a fraction, the numerator of which will be the principal
          amount of Outstanding Auction Rate Series 1998-1 Senior Notes held
          by such Existing Holder subject to such Submitted Bid and the
          denominator of which will be the sum of the principal amount of
          Outstanding Auction Rate Series 1998-1 Senior Notes subject to such
          Submitted Bids made by all such Existing Holders that specified a
          rate equal to the Auction Rate Series 1998-1 Senior Note Interest
          Rate; and

               (e)     Each Potential Holder's Submitted Bid specifying a rate
          that is equal to the Auction Rate Series 1998-1 Senior Note Interest
          Rate will be accepted, but only in an amount equal to the principal
          amount of Auction Rate Series 1998-1 Senior Notes obtained by
          multiplying the excess of the aggregate principal amount of
          Available Auction Rate Series 1998-1 Senior Notes over the aggregate
          principal amount of Auction Rate Series 1998-1 Senior Notes subject
          to Submitted Bids described in subparagraphs (b), (c) and (d) above
          by a fraction, the numerator of which will be the aggregate
          principal amount of Outstanding Auction Rate Series 1998-1 Senior
          Notes subject to such Submitted Bid and the denominator of which
          will be the sum of the principal amount of Outstanding Auction Rate
          Series 1998-1 Senior Notes subject to Submitted Bids

                                     -130-

          made by all such Potential Holders that specified a rate equal to
          the Auction Rate Series 1998-1 Senior Note Interest Rate.

     Insufficient Bids.  If Sufficient Bids have not been made (other than
because all of the Outstanding Auction Rate Series 1998-1 Senior Notes are
subject to Submitted Hold Orders), or if the Auction Rate Series 1998-1 Senior
Note Interest Rate Limitation applies (or if, in the case of the Taxable
Auction Rate Series 1998-1 Senior Notes, the Net Loan Rate is less than the
Bid Auction Rate, in which case the Auction Rate Series 1998-1 Senior Note
Interest Rate for such Notes will be the Net Loan Rate), subject to the
denomination requirements described below, Submitted Orders will be accepted
or rejected as follows in the following order of priority and all other
Submitted Bids will be rejected:

               (a)     Existing Holders' Submitted Bids specifying any rate
          that is equal to or lower than the Auction Rate Series 1998-1 Senior
          Note Interest Rate will be rejected, thus entitling such Existing
          Holders to continue to hold the aggregate principal amount of
          Auction Rate Series 1998-1 Senior Notes subject to such Submitted
          Bids;

               (b)     Potential Holders' Submitted Bids (i) specifying any
          rate that is equal to or lower than the Auction Rate Series 1998-1
          Senior Note Interest Rate will be accepted, and (ii) specifying any
          rate that is higher than the Auction Rate Series 1998-1 Senior Note
          Interest Rate will be rejected; and

               (c)     each Existing Holder's Submitted Bid specifying any
          rate that is higher than the Auction Rate Series 1998-1 Senior Note
          Interest Rate and the Submitted Sell Order of each Existing Holder
          will be accepted, thus entitling each Existing Holder that submitted
          any such Submitted Bid or Submitted Sell Order to sell the Auction
          Rate Series 1998-1 Senior Notes subject to such Submitted Bid or
          Submitted Sell Order, but in both cases only in an amount equal to
          the aggregate principal amount of Auction Rate Series 1998-1 Senior
          Notes obtained by multiplying the aggregate principal amount of
          Auction Rate Series 1998-1 Senior Notes subject to Submitted Bids
          described in subparagraph (b) above by a fraction, the numerator of
          which will be the aggregate principal amount of Outstanding Auction
          Rate Series 1998-1 Senior Notes held by such Existing Holder subject
          to such Submitted Bid or Submitted Sell Order and the denominator of
          which will be the aggregate principal amount of Outstanding Auction
          Rate Series 1998-1 Senior Notes subject to all such Submitted Bids
          and Submitted Sell Orders.

          All Hold Orders.  If all Outstanding Auction Rate Series 1998-1
     Senior Notes are subject to Submitted Hold Orders, all Submitted Bids
     will be rejected.

          Authorized Denominations Requirement.  If, as a result of the
     procedures described above regarding Sufficient Bids and Insufficient
     Bids, any Existing Holder would be entitled or required to sell, or any
     Potential Holder would be entitled or required to purchase, a principal
     amount of Auction Rate Series 1998-1 Senior Notes that is not equal to an
     Authorized Denomination, the Auction Agent will, in such manner as in its
     sole discretion it may determine, round up or down the principal amount
     of Auction Rate Series 1998-1 Senior Notes to be purchased or sold by any
     Existing Holder or Potential Holder so that the principal amount of
     Auction Rate Series 1998-1 Senior Notes purchased or sold by each
     Existing Holder or Potential Holder will be equal to an Authorized
     Denomination.  If, as a result of the procedures described above
     regarding Sufficient Bids, any Potential Holder would be entitled or
     required to purchase less than a principal amount

                                     -131-
<PAGE>
 
     of Auction Rate Series 1998-1 Senior Notes equal to an Authorized
     Denomination, the Auction Agent will, in such manner as in its sole
     discretion it may determine, allocate Auction Rate Series 1998-1 Senior
     Notes for purchase among Potential Holders so that only Auction Rate
     Series 1998-1 Senior Notes in an Authorized Denomination are purchased by
     any Potential Holder, even if such allocation results in one or more of
     such Potential Holders not purchasing any Auction Rate Series 1998-1
     Senior Notes.

     Based on the results of each Auction, the Auction Agent is to determine
the aggregate principal amount of Auction Rate Series 1998-1 Senior Notes to
be purchased and the aggregate principal amount of Auction Rate Series 1998-1
Senior Notes to be sold by Potential Holders and Existing Holders on whose
behalf each Broker-Dealer submitted Bids or Sell Orders and, with respect to
each Broker-Dealer, to the extent that such aggregate principal amount of
Auction Rate Series 1998-1 Senior Notes to be sold differs from such aggregate
principal amount of Auction Rate Series 1998-1 Senior Notes to be purchased,
determine to which other Broker-Dealer or Broker-Dealers acting for one or
more purchasers such Broker-Dealer will deliver, or from which Broker-Dealers
acting for one or more sellers such Broker-Dealer will receive, as the case
may be, Auction Rate Series 1998-1 Senior Notes.

     Any calculation by the Auction Agent (or the Trustee, if applicable) of
the Auction Rate Series 1998-1 Senior Note Interest Rate, Maximum Auction
Rate, One-Month LIBOR, Three-Month LIBOR, All Hold Rate and Non-Payment Rate,
and any calculation by the Corporation or the Servicer of the Net Loan Rate,
will, in the absence of manifest error, be binding on all other parties.

     Notwithstanding anything in the First Supplemental Indenture to the
contrary, no Auction is to be held on any Auction Date during the continuance
of a Payment Default.

     Settlement Procedures

     The Auction Agent is required to advise each Broker-Dealer that submitted
an Order in an Auction of the Auction Rate Series 1998-1 Senior Note Interest
Rate for the next Interest Period and, if such Order was a Bid or Sell Order,
whether such Bid or Sell Order was accepted or rejected, in whole or in part,
by telephone not later than 3:00 p.m., New York City time, on the Auction
Date, if the Auction Rate Series 1998-1 Senior Note Interest Rate is the
Auction Rate; provided that such notice is not required until 4:00 p.m., New
York City time, on the Auction Date, if the Auction Rate Series 1998-1 Senior
Note Interest Rate is the Maximum Auction Rate (or, in the case of the Taxable
Auction Rate Series 1998-1 Senior Notes, the Net Loan Rate).  Each
Broker-Dealer that submitted an Order on behalf of a Bidder is required to
then advise such Bidder of the Auction Rate Series 1998-1 Senior Note Interest
Rate for the next Interest Period and, if such Order was a Bid or a Sell
Order, whether such Bid or Sell Order was accepted or rejected, in whole or in
part, confirm purchases and sales with each Bidder purchasing or selling

result of the Auction to give instructions to its Participant to pay the

     If any Existing Holder selling Auction Rate Series 1998-1 Senior Notes in
an Auction fails to deliver such Auction Rate Series 1998-1 Senior Notes, the
Broker-Dealer of any person that was to have purchased Auction Rate Series
1998-1 Senior Notes in such Auction may deliver to such person a principal
amount of Auction Rate Series 1998-1 Senior Notes that is less than the
principal amount of Auction Rate Series 1998-1 Senior Notes that otherwise was
to be purchased by such person but in any event equal to an Authorized
Denomination.  In such event, the principal amount of Auction Rate Series
1998-1 Senior Notes to be delivered will be determined by such Broker-Dealer.
Delivery of such lesser principal amount of Auction Rate Series 1998-1 Senior
Notes will constitute good delivery.  Neither the Trustee nor the Auction
Agent will have any responsibility or liability with respect to the failure of
a Potential Holder, Existing Holder or their respective Broker-Dealer or
Participant to deliver the principal amount of Auction Rate Series 1998-1
Senior Notes or to pay for the Auction Rate Series 1998-1 Senior Notes
purchased or sold pursuant to an Auction or otherwise.  For a further
description of the settlement procedures, see "Settlement Procedures for
Auction Rate Series 1998-1 Senior Notes."

TRUSTEE NOT RESPONSIBLE FOR AUCTION AGENT, MARKET AGENT AND BROKER-DEALERS

     The Trustee shall not be liable or responsible for the actions of or
failure to act by the Auction Agent, the Market Agent or any Broker-Dealer
under the First Supplemental Indenture, the Auction Agent Agreement or any
Broker-Dealer Agreement.  The Trustee may conclusively rely upon any
information required to be furnished by the Auction Agent, the Market Agent or
any Broker-Dealer without undertaking any independent review or investigation
of the truth or accuracy of such information.

CHANGES IN AUCTION TERMS

     Changes in Auction Period or Periods

     While any of the Auction Rate Series 1998-1 Senior Notes are Outstanding,
the Corporation may, from time to time, change the length of one or more
Auction Periods (an "Auction Period Adjustment") in order to conform with
then-current market practice with respect to similar securities or to
accommodate economic and financial factors that may affect or be relevant to
the length of the Auction Period and the interest rate borne by the Auction
Rate Series 1998-1 Senior Notes.  The Corporation will not initiate such
change in the length of the Auction Period unless it shall have received, not
less than three days nor more than 20 days prior to the Auction Period
Adjustment, (i) in the case of the Tax Exempt Auction Rate Series 1998-1
Senior Notes, a written opinion of Bond Counsel to the effect that such
Auction Period Adjustment will not adversely affect the exclusion of interest
on any of such Notes from income for federal income tax purposes, (ii) the
written consent of the Market Agent, which consent shall not be unreasonably
withheld, and (iii) written confirmation from each of the Rating Agencies then
rating the Auction Rate Series 1998-1 Senior Notes that such Auction Period
Adjustment will not adversely affect its ratings then applicable to any of the
Auction Rate Series 1998-1 Senior Notes.  The Corporation will initiate an
Auction Period Adjustment by giving written notice to the Trustee, the Auction
Agent, the Market Agent and the Securities Depository in substantially the
form of, or containing substantially the information contained in, the First
Supplemental Indenture at least ten days prior to the Auction Date for such
Auction Period.

     Any such Auction Period Adjustment shall not result in an Auction Period
of less than seven days nor more than 91 days.  If any such Auction Period
Adjustment will result in an Auction Period of less than 35 days (in the case
of the Tax Exempt Auction Rate Series 1998-1 Senior Notes) or 28 days (in the
case of the Taxable Auction Rate Series 1998-1 Senior Notes), the notice
described above will be effective only if it is accompanied by a written
statement of the Trustee, the Auction Agent and the Securities Depository to
the effect that they are capable of performing their duties, if any, under the
First Supplemental Indenture, the Auction Agent Agreement and any
Broker-Dealer Agreement with respect to such changed Auction Period.

     An Auction Period Adjustment will take effect only if (A) the Trustee and
the Auction Agent receive, by 11:00 a.m., New York City time, on the Business
Day before the Auction Date for the first such Auction Period, a certificate
from the Corporation authorizing an Auction Period Adjustment specified in
such certificate, the opinion

                                     -133-
<PAGE>
 
of Bond Counsel (in the case of the Tax Exempt Auction Rate Series 1998-1
Senior Notes), the written consent of the Market Agent and the Rating Agency
confirmations described above and, if applicable, the written statement of the
Trustee, the Auction Agent and the Securities Depository described above, and
(B) Sufficient Bids exist at the Auction on the Auction Date for such first
Auction Period.  If the condition referred to in (A) is not met, the Auction
Rate Series 1998-1 Senior Note Interest Rate applicable for the next Auction
Period will be determined pursuant to the Auction Procedures and the Auction
Period will be the Auction Period determined without reference to the proposed
change.  If the condition referred to in (A) is met, but the condition
referred to in (B) above is not met, the Auction Rate Series 1998-1 Senior
Note Interest Rate applicable for the next Auction Period will be (i) with
respect to the Taxable Auction Rate Series 1998-1 Senior Notes, the lesser of
the Maximum Auction Rate and the Net Loan Rate, and (ii) with respect to the
Tax Exempt Auction Rate Series 1998-1 Senior Notes, the Maximum Auction Rate,
and the Auction Period will be the Auction Period determined without reference
to the proposed change.

     Changes in Percentages Used in Determining All Hold Rate, Maximum Auction
Rate and Non-Payment Rate with Respect to the Tax Exempt Auction Rate Series
1998-1 Senior Notes

     The Market Agent may adjust the percentage used in determining the All
Hold Rate, the Applicable Percentage used in determining the Maximum Auction
Rate and the percentage of the Index used in determining the Non-Payment Rate,
in each case with respect to the Tax Exempt Auction Rate Series 1998-1 Senior
Notes, if any such adjustment is necessary, in the judgment of the Market
Agent, to reflect any Change of Tax Law such that a Tax Exempt Auction Rate Seri
es 1998-1 Senior Note bearing interest at the All Hold Rate, a Tax Exempt
Auction Rate Series 1998-1 Senior Note bearing interest at the Maximum Auction
Rate and a Tax Exempt Auction Rate Series 1998-1 Senior Note bearing interest
at the Non-Payment Rate shall have substantially the same market values after
such Change of Tax Law as before such Change of Tax Law.  In making any such
adjustment, the Market Agent shall take the following factors in existence
both before and after such Change of Tax Law into account:  (i) short-term
taxable and tax-exempt market rates and indices of such short-term rates; (ii)
the market supply and demand for short-term tax-exempt securities; (iii) yield
curves for short-term and long-term tax-exempt securities or obligations
having a credit rating that is comparable to the Tax Exempt Auction Rate
Series 1998-1 Senior Notes; (iv) general economic conditions; and (v) economic
and financial factors present in the securities industry that may affect or
that may be relevant to the Tax Exempt Auction Rate Series 1998-1 Senior
Notes.

     The Market Agent shall communicate its determination to adjust the
percentage used in determining the All Hold Rate, the Applicable Percentage
used in determining the Maximum Auction Rate and the percentage of the Index
used in determining the Non-Payment Rate pursuant to the previous paragraph by
means of a written notice delivered in writing at least ten days prior to the
Interest Rate Determination Date on which the Market Agent desires to effect
the change, to the Corporation, the Trustee and the Auction Agent.  Such
notice shall not be given unless the Market Agent has received a Corporation
consent thereto and a written opinion of Bond Counsel to the effect that such
adjustment will not adversely affect the exclusion of interest on any of the
Tax Exempt Auction Rate Series 1998-1 Senior Notes from income for federal incom
e tax purposes.

     Any such adjustment in the percentages used to determine the All Hold
Rate, the Maximum Auction Rate and the Non-Payment Rate with respect to the
Tax Exempt Auction Rate Series 1998-1 Senior Notes shall take effect on an
Interest Rate Determination Date only if (A) the Trustee, the Auction Agent
and the Corporation receive, by 11:00 a.m., New York City time, on the
Business Day immediately preceding such Interest Rate Determination Date, a
Corporation certificate authorizing the adjustment of such percentage,
together with a copy of the Corporation consent thereto and the opinion of
Bond Counsel described above; and (B) the Trustee and the Corporation have
received written confirmation from each of the Rating Agencies then rating the
Tax Exempt Auction Rate Series 1998-1 Senior Notes that such proposed
adjustment will not adversely affect its ratings then applicable to any of the
Tax Exempt Auction Rate Series 1998-1 Senior Notes.  If any of the conditions
referred to in (A) and (B) above are not met, the existing percentage used to
determine the All Hold Rate, Applicable Percentage used to determine the
Maximum Auction Rate and percentage of the Index used to determine the

                                     -134-
<PAGE>
 
Non-Payment Rate shall remain in effect, and the rate of interest on Tax
Exempt Auction Rate Series 1998-1 Senior Notes for the next succeeding
Interest Period shall be determined in accordance with the Auction Procedures.

     Changes in the Auction Date

     The Market Agent, with the written consent of an Authorized Officer of
the Corporation and, in the case of the Tax Exempt Auction Rate Series 1998-1
Senior Notes, upon receipt of the opinion of Bond Counsel as hereinafter
required, may specify an earlier Auction Date (but in no event more than five
Business Days earlier) than the Auction Date that would otherwise be
determined in accordance with the definition of "Auction Date" set forth above
under "Auction Procedures -- General", with respect to one or more specified
Auction Periods in order to conform with then-current market practice with
respect to similar securities or to accommodate economic and financial factors
that may affect or be relevant to the day of the week constituting an Auction
Date and the interest rate on the Auction Rate Series 1998-1 Senior Notes.  No
such change in the Auction Date shall be effective with respect to the Auction
Rate Series 1998-1 Senior Notes unless the Corporation and the Trustee, prior
to the proposed effective date of such change, have received a written opinion
of Bond Counsel to the effect that such change will not adversely affect the
exclusion of interest on any of such Notes from income for federal income tax
purposes.  The Market Agent shall deliver a written request for consent to
such change in the Auction Date to the Corporation not less than three days
nor more than 20 days prior to the effective date of such change.  The Market
Agent shall provide notice of its determination to specify an earlier Auction
Date for one or more Auction Periods by means of a written notice delivered at
least ten days prior to the proposed changed Auction Date to the Trustee, the
Auction Agent, the Corporation and the Securities Depository.  Such notice
will be substantially in the form of, or contain substantially the information
contained in, the First Supplemental Indenture.

     Notice of Changes in Auction Terms

     In connection with any change in Auction Terms described above, the
Auction Agent is to provide such further notice to such parties as is
specified in the Auction Agent Agreement.

     (f)     If an Existing Holder selling Auction Rate Series 1998-1 Senior
Notes in an Auction fails to deliver such Auction Rate Series 1998-1 Senior
Notes (by authorized book-entry), a Broker-Dear may deliver to the Potential

amount of Auction Rate Series 1998-1 Senior Notes that is less than the
principal amount of Auction Rate Series 1998-1 Senior Notes that otherwise was
to be purchased by such Potential Holder.  In such event, the principal amount
of Auction Rate Series 1998-1 Senior Notes to be so delivered will be
determined solely by such Broker-Dealer.  Delivery of such lesser principal
amount of Auction Rate Series 1998-1 Senior Notes will constitute good
delivery.  Notwithstanding the foregoing terms of this paragraph (f), any
delivery or nondelivery of Auction Rate Series 1998-1 Senior Notes which will
represent any departure from the results of an Auction, as determined by the
Auction Agent, will be of no effect unless and until the Auction Agent will
have been notified of such delivery or nondelivery in accordance with the
provisions of the Auction Agent Agreement and the Broker-Dealer Agreements.
Neither the Trustee nor the Auction Agent will have any responsibility or
liability with respect to the failure of a Potential Holder, Existing Holder
or their respective Broker-Dealer or Participant to take delivery of or
deliver, as the case may be, the principal amount of the Auction Rate Series
1998-1 Senior Notes purchased or sold pursuant to an Auction or otherwise.


                           SUMMARY OF THE INDENTURE

     The following is a summary of the material provisions of the Indenture
and the First Supplemental Indenture and is not to be considered as a full
statement of the provisions of the Indenture or the First Supplemental
Indenture.  The summary is qualified by reference to and is subject to the
complete Indenture and the First Supplemental Indenture, which are
incorporated by reference herein.  Copies thereof, in reasonable quantity, may
be obtained during the offering period upon request directed to Education
Loans Incorporated, Attention:  President, 105 First Avenue Southwest,
Aberdeen, South Dakota 57401.  Although the following summary refers to the
"Corporation" only, the use of such term should also be read to include the
Original Issuer prior to the Section 150(d)(3) Transfer.

     The Indenture establishes the general provisions of Notes issued by the
Corporation thereunder and sets forth various covenants and agreements of the
Corporation relating thereto, default and remedy provisions, responsibilities
and duties of the Trustee and establishes the various Funds into which the
Corporation's revenues related to the Notes are deposited and transferred for
various purposes.  The First Supplemental Indenture provides for the specific
terms and details of the Series 1998-1 Notes, pledges the Financed Student
Loans and the revenues related thereto and establishes the various Accounts in
the Funds related to the Series 1998-1 Notes.

GENERAL TERMS OF NOTES

     Each series of Notes shall be created by and issued pursuant to a
Supplemental Indenture and such Supplemental Indenture shall designate Notes
of each series as Senior Notes, Subordinate Notes or Class C Notes.  The Notes
of each series shall bear such date or dates, shall be payable at such place
or places, shall have such Principal Payment Dates, shall bear interest at
such rate or rates, from such date or dates, payable in such installments and
on Interest Payment Dates and at such place or places, and may be subject to
prepayment or call for redemption at such Redemption Price or Prices and upon
such terms, as shall be provided for in the Supplemental Indenture creating
that series.

     The Stated Maturities and Sinking Fund Payment Dates of all Notes shall
occur on a June 1 or a December 1, unless otherwise specified with respect to
any series of Variable Rate Notes in the Supplemental Indenture providing for
the issuance thereof.  All Corporation Swap Payments and other payments to be
made by the Corporation to Credit Facility Providers shall be payable on a
regularly scheduled Interest Payment Date.

     Except as may be otherwise provided in a Supplemental Indenture, in any
case where the principal of, premium, if any, or interest on the Notes or
amounts due to any Other Beneficiary shall be due on a day other than a
Business Day, then payment of such principal, premium and interest or such
amounts may be made on the next

                                     -138-
<PAGE>
 
succeeding Business Day with the same force and effect as if made on the date
due and no interest shall accrue for the intervening period.

     In the event a default occurs in the due and punctual payment of any
interest on any Note, interest shall be payable thereon to the extent
permitted by law on the overdue installment of interest, at the interest rate
borne by the Note in respect of which such interest is overdue.

     The Notes, including the principal thereof, premium, if any, and interest
thereon and any Carry-Over Amounts (and accrued interest thereon) with respect
thereto, and Other Indenture Obligations are limited obligations of the
Corporation, payable solely from the revenues and assets of the Corporation
pledged therefor under the Indenture.

ADDITIONAL NOTES

     Notes shall be issued under the Indenture only for the purposes of (a)
providing funds for the origination or purchase, or both, by the Trustee on
behalf of the Corporation or by the Corporation of Eligible Loans (including,
for this purpose, the acquisition under the Indenture of Eligible Loans
previously purchased or originated by the Corporation from other available
moneys of the Corporation), (b) refunding at or before their Stated Maturity
any or all Outstanding Notes issued for that purpose, and (c) paying
Administrative Costs, Note Fees, Costs of Issuance and capitalized interest on
the Notes being issued and making deposits to the Reserve Fund.

     At any time, one or more series of Notes may be issued in such principal
amounts as may be determined by the Corporation for any of the purposes
hereinbefore specified upon compliance with certain conditions specified in
the Indenture (including the requirement that each Rating Agency shall have
confirmed that no outstanding ratings on any of the Outstanding Unenhanced
Notes will be reduced or withdrawn as a result of such issuance) and any
additional conditions specified in a Supplemental Indenture.  Any Additional
Notes will not be offered or sold pursuant to this Prospectus.

COMPARATIVE SECURITY OF NOTEHOLDERS AND OTHER BENEFICIARIES

     The Senior Notes (including the Series 1998-1 Senior Notes) are equally
and ratably secured under the Indenture with any Other Senior Obligations.
The Senior Obligations have payment and certain other priorities over the
Subordinate Notes, the Other Subordinate Obligations and the Class C Notes.
The Subordinate Notes (including the Series 1998-1 Subordinate Notes) are
equally and ratably secured under the Indenture with any Other Subordinate
Obligations.  The Subordinate Obligations have payment and certain other
priorities over the Class C Notes.  (See "Source of Payment and Security for
the Notes -- Priorities" in this Prospectus.)  The Senior Notes and the
Subordinate Notes are each payable from the Note Fund and are secured by the
Reserve Fund.  The Class C Notes are payable solely from the Surplus Fund.

     The Corporation may at any time issue a series of Notes as described
under "Additional Notes" above, either as Senior Notes, Subordinate Notes or
Class C Notes. (Any Additional Notes will not be offered or sold pursuant to
this Prospectus.)  In connection with any such Senior Notes or Subordinate
Notes, the Corporation may enter into a Swap Agreement or Credit Enhancement
Facility as it deems in its best interest, subject to the provisions described
in the next succeeding paragraphs, and the Swap Counterparty or the Credit
Enhancement Provider may become a Senior Beneficiary or a Subordinate
Beneficiary, as herein described.

     The Corporation may enter into a Swap Agreement only if the Swap
Counterparty has outstanding obligations rated by each Rating Agency not lower
that in its third highest Specific Rating Category (or each Rating Agency has
a comparable other rating with respect to such Swap Counterparty, such as a
comparable rating of claims paying ability or deposits).  No Swap Agreement
shall be designated as a Senior Swap Agreement unless, as of the date the
Corporation enters into such Swap Agreement, the Senior Asset Requirement will
be met and the Trustee shall have received written confirmation from each
Rating Agency that the execution and delivery of the

                                     -139-
<PAGE>
 
Swap Agreement will not cause the reduction or withdrawal of any rating or
ratings then applicable to any Outstanding Unenhanced Notes.

CALL FOR REDEMPTION, PREPAYMENT OR PURCHASE OF NOTES; SENIOR ASSET REQUIREMENT

     No call for redemption (other than mandatory sinking fund redemption of
Senior Term Notes), prepayment of principal or purchase (other than on a
Purchase Date or Mandatory Tender Date) of Notes by the Trustee shall be
effective under the Indenture unless, prior to the Trustee giving notice of
call for redemption, determining that such prepayment will be made or
soliciting such purchase, the Corporation furnishes the Trustee a Corporation
certificate to the effect that:

          1.     if Senior Notes are to be called for redemption prepaid or
    purchased, either (A) after giving effect to such call for redemption,
    prepayment or purchase, the Senior Asset Requirement will be met, or (B)
    (i) prior to such call for redemption, prepayment or purchase, the Senior
    Asset Requirement is not being met, (ii) no Subordinate Notes or Class C
    Notes will be called for redemption on the Redemption Date, prepaid on the
    Prepayment Date or purchased on the purchase date for the Senior Notes
    then proposed to be called for redemption, prepaid or purchased, and (iii)
    after giving effect to such call for redemption, prepayment or purchase,
    the Senior Percentage will be greater than it would have been without such
    call for redemption, prepayment or purchase;

          2.     if Subordinate Notes are to be called for redemption, prepaid
    or purchased, after giving effect to such call for redemption, prepayment
    or purchase, the Senior Asset Requirement will be met; and

          3.     if Class C Notes are to be called for redemption, prepaid or
    purchased, after giving effect to such call for redemption, prepayment or
    purchase, the Senior Asset Requirement will be met and there shall be no
    deficiency then existing in the Note Fund, the Reserve Fund or the Rebate
    Fund.

     In general, compliance with the foregoing conditions is determined as of
the date of selection of Notes to be called for redemption or as of the date
on which moneys are transferred to the Retirement Account to make any
prepayment and any failure to satisfy such conditions as of the Redemption
Date or Prepayment Date, as applicable, will not affect such determination;
provided that, if Notes have been defeased and are to be called for
redemption, compliance with such conditions will be determined on the date of
defeasance instead of as of the date of selection.  (See "Discharge of Notes
and Indenture" below.)

     Any election to call Notes for redemption or to prepay Notes may also be
conditioned upon such additional requirements as may be set forth in the
Supplemental Indenture authorizing the issuance of such Notes.

FUNDS AND ACCOUNTS

     Acquisition Fund

     The Indenture establishes an Acquisition Fund.  With respect to each
series of Notes, the Trustee shall, upon delivery to the initial purchasers
thereof and from the proceeds thereof, credit to the Acquisition Fund the
amount, if any, specified in the Supplemental Indenture providing for the
issuance of such series of Notes.  The Trustee shall also deposit in the
Acquisition Fund: (i) any funds to be transferred thereto from the Surplus
Fund, and (ii) any other amounts specified in a Supplemental Indenture.  In
addition, the Trustee shall also credit to the Acquisition Fund any Eligible
Loans transferred thereto from the Surplus Account as described under "Surplus
Fund" below (any such Eligible Loans so transferred being thereafter deemed to
have been Financed with moneys in the Acquisition Fund).

                                     -140-
<PAGE>
 
     Balances in the Acquisition Fund shall be used only for (a) the purchase
or origination of Eligible Loans, (b) the redemption of Notes which are called
for redemption or the purchase of Notes as provided in a Supplemental
Indenture providing for the issuance of such series of Notes, (c) the payment
of Debt Service on the Senior Notes and Other Senior Obligations when due, (d)
the payment of the purchase price of any Senior Notes required to be purchased
on a Purchase Date or a Mandatory Tender Date, or (e) to cure deficiencies in
the Rebate Fund.  The Trustee shall make, or authorize any Deposit Agent to
make, payments to Lenders from the Acquisition Fund for the acquisition of
Eligible Loans, such payments to be made from the Series 1998-1 Tax Exempt and
Taxable Acquisition Accounts at a purchase price not in excess of 100% of the
remaining unpaid principal amount of such Eligible Loan, plus accrued
noncapitalized borrower interest thereon, if any, to the date of purchase,
reasonable transfer, origination or assignment fees, if applicable, and a
premium not to exceed certain limitations set forth in the First Supplemental
Indenture.  The Trustee shall also make, or authorize the Deposit Agent to
make, payments from the Acquisition Fund for the origination of Eligible
Loans.

     Balances in the Acquisition Fund (other than any portion of such Balances
consisting of Student Loans) shall be (i) transferred to the credit of the
Rebate Fund to the extent necessary, after transfers thereto from the Revenue
Fund, the Surplus Fund, the Reserve Fund, the Administration Fund and the Note
Fund, to make any deposit to the credit of the Rebate Fund as described under
"Rebate Fund" below, (ii) after such transfer, if any, to be made pursuant to
the preceding clause (i) has been taken into account, transferred to the
credit of the Note Fund on the last Business Day preceding any Interest
Payment Date, Principal Payment Date or Redemption Date to the extent required
to pay the Debt Service due on the Senior Notes and any Other Senior
Obligations, as described under "Note Fund" below, and (iii) after such
transfers, if any, to be made pursuant to the preceding clauses (i) and (ii)
have been taken into account, transferred to the credit of the Principal
Account on any Purchase Date or Mandatory Tender Date with respect to Senior
Notes, to the extent described under "Note Fund" below.  In the event that,
after transfers to the Rebate Fund from all other Funds and Accounts, a
deficiency exists in the Rebate Fund, the Trustee shall use its best efforts
to sell Student Loans included in the Balance of the Acquisition Fund at the
best price available to the extent of such deficiency; and the proceeds of any
such sale shall be credited to the Rebate Fund, to the extent of any
deficiency in the Rebate Fund, and otherwise to the Revenue Fund.  If any
amounts have been transferred to either or both of the Rebate Fund or the Note
Fund pursuant to this paragraph, the Trustee shall, to the extent necessary to
cure the deficiency in the Acquisition Fund as a result of such transfer or
transfers, transfer to the Acquisition Fund amounts from the Revenue Fund as
described below under "Revenue Fund".

     Pending application of moneys in the Acquisition Fund for one or more
authorized purposes, such moneys shall be invested in Investment Securities,
as described under "Investments" below, and any earnings on or income from
said investments shall be deposited in the Revenue Fund.

     Revenue Fund

     The Indenture establishes a Revenue Fund, which is comprised of two
Accounts: the Repayment Account and the Income Account.  The Trustee and any
Deposit Agent shall credit to the Revenue Fund: (i) all amounts received as
interest, including federal interest subsidy payments, and principal payments
with respect to Financed Student Loans, including all Guarantee payments and
all Special Allowance Payments with respect to Financed Student Loans
(excluding, except in the case of the Eligible Loans to be Financed on the
Date of Issuance and as otherwise provided in a Supplemental Indenture, any
federal interest subsidy payments and Special Allowance Payments that accrued
prior to the date on which such Student Loans were Financed), (ii) unless
otherwise provided in a Supplemental Indenture, proceeds of the resale to a
Lender of any Financed Student Loans pursuant to such Lender's repurchase
obligation under the applicable Student Loan Purchase Agreement, (iii) all
amounts received as earnings on or income from Investment Securities in the
Acquisition Fund, the Reserve Fund, the Administration Fund, the Surplus Fund
and the Note Fund, and (iv) all amounts to be transferred to the Revenue Fund
from the Rebate Fund.  The Trustee shall deposit and credit all such amounts
received as payments of principal of Financed Student Loans to the Repayment
Account, and all other such amounts to the Income Account.

                                     -141-

any periodic rebate fee payments required to be made to the Secretary of
Education in connection with Financed Student Loans, and (2) transfer the

     Note Fund

     The Indenture establishes a Note Fund, which is comprised of three
Accounts:  the Interest Account, the Principal Account and the Retirement
Account.  The Note Fund shall be used only for the payment when due of
principal of, premium, if any, and interest on the Senior Notes and the
Subordinate Notes, the purchase price of Senior Notes and Subordinate Notes to
be purchased on a Purchase Date or Mandatory Tender Date in accordance with
the Indenture, Other Indenture Obligations and Carry-Over Amounts (including
any accrued interest thereon) and to make transfers to the credit of the
Rebate Fund.  The principal of and interest on the Class C Notes are payable
from the Surplus Fund.

     Interest Account.  The Trustee shall deposit in the Interest Account (i)
that portion of the proceeds from the sale of Financed Student Loans
representing accrued interest and Special Allowance Payments thereon, (ii)
that portion of the proceeds from the sale of the Corporation's bonds, notes
or other evidences of indebtedness, if any, to be used to pay interest on the
Senior Notes or the Subordinate Notes, (iii) all Counterparty Swap Payments,
(iv) all payments under any Credit Enhancement Facilities to be used to pay
interest on (or the interest portion of the purchase price of) the Notes and
(v) all amounts required to be transferred thereto from the Funds and Accounts
specified in the last sentence of the following paragraph.  The moneys in the
Interest Account shall be invested in Investment Securities as described under
"Investments" below, and any earnings on or income from such investments shall
be deposited in the Revenue Fund.

     To provide for the payment of each installment of interest which falls
due upon Senior Notes or Subordinate Notes on each regularly scheduled
Interest Payment Date and all Corporation Swap Payments and fees to a Credit
Facility Provider payable on such Interest Payment Date, the Trustee shall
make deposits to the credit of the Interest Account on each Monthly Payment
Date (less certain credits against such payments).  If, on any Interest
Payment

                                     -143-
<PAGE>
 
Date (including a Redemption Date or a date that Notes are to be purchased
that is not a regularly scheduled Interest Payment Date), moneys in the
Interest Account are insufficient to pay the accrued interest due on the
Senior Notes and Subordinate Notes and all Corporation Swap Payments and fees
to a Credit Enhancement Facility Provider payable on such Interest Payment
Date or constituting a portion of the purchase price of Notes to be so
purchased, the Trustee shall deposit immediately to the credit of the Interest
Account an amount equal to such deficiency.  Each deposit required by this
paragraph shall be made by transfer from the following Funds and Accounts, in
the following order of priority:  the Revenue Fund, the Surplus Fund (other
than that portion of the Balance thereof consisting of Eligible Loans), the
Reserve Fund, the Administration Fund, the Surplus Fund (including any portion
of the Balance thereof consisting of Eligible Loans), the Retirement Account,
the Principal Account and, as to Senior Notes and Other Senior Obligations
only, the Acquisition Fund (other than that portion of the Balance thereof
consisting of Student Loans); provided that such transfers in respect of
Subordinate Notes or Other Subordinate Obligations shall be so made from the
Principal Account or the Retirement Account only if, and to the extent, any
amounts to be so transferred are in excess of the requirements of such
Accounts with respect to Senior Obligations payable therefrom.

     If, as of any regularly scheduled Interest Payment Date, any Carry-Over
Amount (including any accrued interest thereon) is due and payable with
respect to a series of Notes, as provided in the related Supplemental
Indenture, the Trustee shall transfer to the Interest Account (to the extent
amounts are available therefor in the Surplus Account, after taking into
account all other amounts payable from the Surplus Fund on such Interest
Payment Date) an amount equal to such Carry-Over Amount (including any accrued
interest thereon) so due and payable.

     Balances in the Interest Account shall be transferred to the credit of
the Rebate Fund to the extent necessary, after transfers thereto from the
Revenue Fund, the Surplus Fund, the Reserve Fund, the Administration Fund, the
Retirement Account and the Principal Account, to make any deposit to the
credit of the Rebate Fund required by the Indenture.  (See "Rebate Fund"
below.)

     Apart from transfers to the Rebate Fund and transfers to the Principal
Account as described under "Principal Account" below, Balances in the Interest
Account shall be applied, first, to the payment of interest on all Senior
Notes, Corporation Swap Payments under Senior Swap Agreements and fees payable
to Senior Credit Enhancement Providers due on an Interest Payment Date, and if
such money (after the transfers hereinabove described, including all amounts,
to the extent necessary, in the Principal Account) is less than such interest
and Other Senior Obligations on such Interest Payment Date, such money shall
be applied, pro rata, among such indebtedness based upon such amounts then
owing to Senior Beneficiaries and to be paid from the Interest Account;
second, to the payment of interest on all Subordinate Notes, Corporation Swap
Payments under Subordinate Swap Agreements and fees payable to Subordinate
Credit Enhancement Providers due on an Interest Payment Date, and if such
money (after the transfers hereinabove described, including all amounts, to
the extent necessary, in the Principal Account over and above the amount on
deposit therein to meet any accrued obligations to pay principal of the Senior
Notes or amounts, other than fees, to Senior Credit Facility Providers) is
less than such interest and Other Subordinate Obligations on such Interest
Payment Date, such money shall be applied, pro rata, among such indebtedness
based upon such amounts then owing to Subordinate Beneficiaries and to be paid
from the Interest Account; third, to the payment of all Carry-Over Amounts
(including any accrued interest thereon) due and payable on all series of
Senior Notes, and if such money is less than such Carry-Over Amounts
(including any accrued interest thereon) on an Interest Payment Date, such
money shall be applied, pro rata, among such Carry-Over Amounts (including any
accrued interest thereon) based upon such amounts then otherwise due and
payable to Senior Noteholders and to be paid from the Interest Account; and
fourth, to the payment of all Carry-Over Amounts (including any accrued
interest thereon) due and payable on all series of Subordinate Notes, and if
such money is less than such Carry-Over Amounts (including any accrued
interest thereon) on an Interest Payment Date, such money shall be applied,
pro rata, among such Carry-Over Amounts (including any accrued interest
thereon) based upon such amounts then otherwise due and payable to Subordinate
Noteholders and to be paid from the Interest Account.

                                     -144-
<PAGE>
 
     Other Indenture Obligations payable from the Interest Account will
include reimbursement to any Credit Facility Provider for interest paid on
Senior Notes or Subordinate Notes from amounts derived from the related Credit
Enhancement Facility, which reimbursement shall have the same priority of
payment from the Interest Account as the interest so paid.

     Principal Account.  The Trustee shall deposit to the credit of the
Principal Account: (i) that portion of the proceeds from the sale of Financed
Student Loans representing principal thereof, (ii) that portion of the
proceeds from the sale of the Corporation's bonds, notes or other evidences of
indebtedness, if any, to be used to pay principal of the Senior Notes and the
Subordinate Notes, (iii) all payments under any Credit Enhancement Facilities
to be used to pay principal of Senior Notes or Subordinate Notes or the
purchase price of Senior Notes or Subordinate Notes to be purchased on a
Purchase Date or Mandatory Tender Date, and (iv) all amounts required to be
transferred thereto from the following Funds, in the following order of
priority:  (1) in the case of payment of principal of Notes at Stated
Maturity, redemption of Senior Notes called for redemption on a Sinking Fund
Payment Date or the purchase of Notes on a Purchase Date or Mandatory Tender
Date, the Revenue Fund, the Surplus Fund (other than that portion of the
Balance thereof consisting of Eligible Loans), the Reserve Fund, the
Administration Fund and the Surplus Fund (including any portion of the Balance
thereof consisting of Eligible Loans), and (2) in the case of redemption of
Subordinate Notes called for redemption on a Sinking Fund Payment Date, the
Revenue Fund and the Surplus Fund (other than that portion of the Balance
thereof consisting of Eligible Loans); provided, however, that if principal is
payable on Senior Notes at the Stated Maturity thereof or upon a Sinking Fund
Payment Date therefor, or the purchase price is payable on Senior Notes on a
Purchase Date or Mandatory Tender Date, and money credited to the Principal
Account, after the foregoing transfers, is insufficient to pay such principal
or purchase price, funds shall be transferred, to the extent necessary, to the
Principal Account for this purpose, (i) from the Interest Account, but only to
the extent that the Balance in the Interest Account exceeds any then accrued
payments of interest on the Senior Notes, Corporation Swap Payments under
Senior Swap Agreements and fees owing to Senior Credit Enhancement Providers
and (ii) thereafter from the Acquisition Fund (other than that portion of the
Balance thereof consisting of Student Loans).

     To provide for the payment of principal due on the Stated Maturity of
Senior or Subordinate Serial Notes or on a Sinking Fund Payment Date for
Senior or Subordinate Term Notes, the Trustee shall make deposits to the
credit of the Principal Account on each Monthly Payment Date from amounts
available therefor in the Revenue Fund and the other Funds referred to above.
To the extent there are not available moneys to make any monthly payment with
respect to the cumulative sinking fund redemption of Subordinate Term Notes,
subsequent monthly payments shall be increased to make up any such deficiency,
and to the extent that on any Sinking Fund Payment Date the aggregate of such
payments actually made as of the next-to-the-last Monthly Payment Date prior
to such Sinking Fund Payment Date is less than the amount of the sinking fund
installment due on such Sinking Fund Payment Date, the amount of such
deficiency shall be added to the amount of the sinking fund installment due on
the next Sinking Fund Payment Date, and the increased amount thereupon shall
be deemed to be the amount due for such next sinking fund installment.
However, the requirement for payments of cumulative sinking fund installments
on Subordinate Term Notes shall not be construed to create an Event of Default
in the event of any such deficiency (other than, under certain circumstances,
in amounts due with respect to the Stated Maturity of Subordinate Term Notes)
unless a sinking fund installment of such Subordinate Term Notes shall not
only be due and not applied to the redemption of Subordinate Term Notes which
are called for redemption or the purchase of Subordinate Term Notes, but also
that all contingencies upon the obligation so to apply it as of such time in
fact have been satisfied.

     In the event that the Corporation is required to furnish moneys to the
Depositary to purchase Notes on a Purchase Date or Mandatory Tender Date, the
Trustee shall, subject to the applicable provisions of the related
Supplemental Indenture, immediately deposit to the credit of the Principal
Account moneys sufficient to pay the purchase price thereof.

     Balances in the Principal Account shall be transferred to the credit of
the Rebate Fund to the extent necessary, after transfers thereto from the
Revenue Fund, the Surplus Fund, the Reserve Fund, the Administration

                                     -145-
<PAGE>
 
Fund and the Retirement Account, to make any required deposit to the credit of
the Rebate Fund.  (See "Rebate Fund" below.)

     Balances to the credit of the Principal Account shall be applied in the
following order of priority:  first, to the extent required by the immediately
preceding paragraph, for transfer to the Rebate Fund; second, to the Interest
Account to the extent required (see "Interest Account" above) for the payment
of interest on Senior Notes and Other Senior Obligations payable therefrom;
third, to the payment of Senior Notes at their Stated Maturity or on their
Sinking Fund Payment Date and Other Senior Obligations payable therefrom;
fourth, to the payment of the purchase price of Senior Notes on a Purchase
Date or Mandatory Tender Date; fifth, to the Interest Account to the extent
required (see "Interest Account" above) for the payment of interest on
Subordinate Notes and Other Subordinate Obligations payable therefrom; sixth,
to the payment of Subordinate Notes at their Stated Maturity and Other
Subordinate Obligations payable therefrom; seventh, to the payment of the
purchase price of Subordinate Notes on a Purchase Date or Mandatory Tender
Date; and eighth, to the payment of Subordinate Term Notes on a Sinking Fund
Payment Date.

     Other Indenture Obligations payable from the Principal Account will
include reimbursement to any Credit Facility Provider for principal or the
purchase price paid on Senior Notes or Subordinate Notes from amounts derived
from the related Credit Enhancement Facility, which reimbursement shall have
the same priority of payment from the Principal Account as the principal so
paid.

     Subject to compliance with the provisions of the Indenture described
under "Call for Redemption, Prepayment or Purchase of Notes; Senior Asset
Requirement" above, Balances in the Principal Account may also be applied to
the purchase of Senior Notes or Subordinate Notes at a purchase price
(including any brokerage or other charges) not to exceed the Principal Amount
thereof plus accrued interest, as determined by the Corporation at such time,
provided the Trustee shall have first certified that no deficiencies exist at
such time in the Note Fund or the Rebate Fund.  Any such purchase shall be
limited to those Senior Notes or Subordinate Notes whose Stated Maturity or
Sinking Fund Payment Date is the next succeeding Principal Payment Date.

     The moneys in the Principal Account shall be invested in Investment
Securities as described under "Investments" below, and any earnings on or
income from such investments shall be deposited in the Revenue Fund.

     Retirement Account.  The Trustee shall deposit to the credit of the
Retirement Account (i) any amounts transferred thereto from the Reserve Fund
and the Surplus Fund, (ii) that portion of the proceeds from the sale of the
Corporation's bonds, notes or other evidences of indebtedness, if any, to be
used to pay the principal or Redemption Price of Senior Notes or Subordinate
Notes on a date other than the Stated Maturity thereof or a Sinking Fund
Payment Date therefor, and (iii) all payments under any Credit Enhancement
Facilities to be used to pay the Redemption Price of Notes payable from the
Retirement Account.  All Senior Notes or Subordinate Notes which are to be
retired, or the principal of which is to be prepaid, other than with moneys in
the Principal Account shall be retired or prepaid with moneys deposited to the
credit of the Retirement Account.

     Balances in the Retirement Account shall be transferred to the credit of
the Rebate Fund to the extent necessary, after transfers thereto from the
Revenue Fund, the Surplus Fund, the Reserve Fund and the Administration Fund,
to make any required deposit to the Rebate Fund.  (See "Rebate Fund" below.)
After taking into account any such required transfers to the Rebate Fund,
Balances in the Retirement Account shall be transferred to the credit of the
Interest Account to the extent required (see "Interest Account" above) for the
payment of interest on Notes and Other Indenture Obligations payable
therefrom.

     Other Indenture Obligations payable from the Retirement Account will
include reimbursement to any Credit Facility Provider for the Redemption Price
paid on Senior Notes or Subordinate Notes from amounts derived from the
related Credit Enhancement Facility, which reimbursement shall have the same
priority of payment from the Retirement Account as the Redemption Price so
paid.

     Subject to compliance with the provisions of the Indenture described
under "Call for Redemption, Prepayment or Purchase of Notes; Senior Asset
Requirement" above, Balances in the Retirement Account (other than any portion
thereof to be applied to the mandatory prepayment of principal of any Notes)
may also be applied to the purchase of Senior Notes or Subordinate Notes at a
purchase price (including any brokerage or other charges) not to exceed the
Principal Amount thereof plus accrued interest plus any then applicable
redemption premium, as determined by the Corporation at such time; provided
the Trustee shall have first certified that no deficiencies exist at such time
in the Note Fund or the Rebate Fund.

     The moneys in the Retirement Account shall be invested in Investment
Securities as described under "Investments" below, and any earnings on or
income from such investment shall be deposited in the Revenue Fund.

     Administration Fund

     With respect to each series of Notes, the Trustee shall, upon delivery
thereof and from the proceeds thereof, credit to the Administration Fund
established under the Indenture the amount, if any, specified in the
Supplemental Indenture providing for the issuance of such series of Notes.
The Trustee shall also credit to the Administration Fund all amounts
transferred thereto from the Revenue Fund and the Surplus Account.  Amounts in
the Administration Fund shall be used to pay Costs of Issuance, Administrative
Expenses and Note Fees or to reimburse another fund, account or other source
of the Corporation for the previous payment of Costs of Issuance,
Administrative Expenses or Note Fees.  Balances in the Administration Fund
shall also be applied to remedy deficiencies in the Rebate Fund and the Note
Fund after transfers thereto from the Revenue Fund, the Surplus Fund (other
than that portion of the Balance thereof consisting of Eligible Loans) and the
Reserve Fund.

     The Trustee shall transfer and credit to the Administration Fund moneys
available under the Indenture for transfer thereto from the sources set forth
in the following paragraph and in such amounts and at such times as an
Authorized Officer of the Corporation shall direct by Corporation order;
provided such Corporation order shall certify that the amounts are required
and have been or will be expended within the next 90 days for a purpose for
which the Administration Fund may be used and applied.

     Deposits to the credit of the Administration Fund shall be made from the
following sources in the following order of priority:  the Income Account
after transfers therefrom to the Rebate Fund, the Interest Account, the
Principal Account (other than with respect to the payment of sinking fund
installments for Subordinate Notes), and the Retirement Account; and the
Surplus Account after transfers therefrom to the Rebate Fund, the Interest
Account, the Principal Account (other than with respect to the payment of
sinking fund installments for Subordinate Notes) and the Retirement Account,
provided that any such deposit from the Surplus Account shall only be made to
the extent that portion of the Balance thereof not consisting of Eligible
Loans is sufficient therefor.

     Pending transfers from the Administration Fund, the moneys therein shall
be invested in Investment Securities, as described under "Investments" below,
and any earnings on or income from such investments shall be deposited in the
Revenue Fund.

     Reserve Fund

     The Reserve Fund is established under the Indenture only for the security
of the Senior Beneficiaries and the Subordinate Beneficiaries, and not for the
Holders of the Class C Notes (other than to provide funds for transfers to the
Rebate Fund for Tax Exempt Class C Notes as hereinafter described).
Immediately upon the delivery of any series of Senior Notes or Subordinate
Notes, and from the proceeds thereof or, at the option of the Corporation,
from any amounts to be transferred thereto from the Surplus Fund and from any
other available moneys of the Corporation not otherwise credited to or payable
into any Fund or Account under the Indenture or otherwise subject to the
pledge and security interest created by the Indenture, the Trustee shall
credit to the Reserve Fund the amount, if any, specified in the Supplemental
Indenture providing for the issuance of that series of Notes, such that, upon
issuance of such Notes, the Balance in the Reserve Fund shall not be less than
the Reserve Fund Requirement.

                                     -147-
<PAGE>
 
     If on any Monthly Payment Date the Balance in the Reserve Fund is less
than the Reserve Fund Requirement, the Trustee shall transfer and credit
thereto an amount equal to the deficiency from moneys available therefor in
the following Funds and Accounts in the following order of priority:  the
Repayment Account, the Income Account and the Surplus Fund; provided that any
such transfer from the Surplus Fund shall only be made to the extent that
portion of the Balance thereof not consisting of Eligible Loans is sufficient
therefor.

     The Balance in the Reserve Fund shall be used and applied solely for (i)
transfers to the Rebate Fund to the extent necessary, after transfers thereto
from the Revenue Fund and the Surplus Fund (other than that portion of the
Balance thereof consisting of Eligible Loans), to make any required deposit to
the Rebate Fund (see "Rebate Fund" below), and (ii) after such transfer, if
any, to be made pursuant to the preceding clause (i) has been taken into
account, the payment when due of principal and interest on the Senior Notes
and the Subordinate Notes and any Other Indenture Obligations and the purchase
price of Senior Notes and Subordinate Notes on a Purchase Date or Mandatory
Tender Date, and the other purposes specified in the Indenture (see "Note
Fund" above), and shall be so used and applied by transfer by the Trustee to
the credit of the Note Fund, (a) at any time and to the extent that the
Balance therein and the Balances available for deposit to the credit thereof
from the Revenue Fund and the Surplus Fund (other than that portion of the
Balance thereof consisting of Eligible Loans) are insufficient to meet the
requirements specified in the Indenture for deposit to the credit of the Note
Fund at such time (provided, however, that such amounts shall be applied,
first, to the payment of interest on the Senior Notes and Other Senior
Obligations payable from the Interest Account, second, to the payment of
principal and the purchase price of Senior Notes and Other Senior Obligations
payable from the Principal Account, third, to the payment of interest on the
Subordinate Notes and Other Subordinate Obligations payable from the Interest
Account, and, fourth, to the payment of principal and the purchase price of
Subordinate Notes and Other Subordinate Obligations payable from the Principal
Account) and (b) at any time when a portion of the Balance therein is required
to be transferred to the Retirement Account to pay a portion of the Redemption
Price of Senior Notes or Subordinate Notes called for redemption as provided
in a Supplemental Indenture relating thereto.  If on any Monthly Payment Date
the Balance in the Reserve Fund exceeds the Reserve Fund Requirement, such
excess shall, upon Corporation order, be transferred to the Principal Account,
to the extent necessary to make the deposits required to be made to the credit
of the Principal Account on such Monthly Payment Date, whether or not other
moneys are available to make such deposits.

     Pending transfers from the Reserve Fund, the moneys therein shall be
invested in Investment Securities as described under "Investments" below and
any earnings on or income from such investments shall be deposited in the
Revenue Fund.

     Rebate Fund

     The Indenture establishes a Rebate Fund, which is comprised of two
Accounts:  the Rebate Account and the Excess Earnings Account.

     Rebate Account.  The Trustee shall deposit to the credit of the Rebate
Account amounts from the Balances in the Revenue Fund, the Surplus Fund (other
than that portion of the Balance thereof consisting of Eligible Loans), the
Reserve Fund, the Administration Fund, the Surplus Fund (including any portion
of the Balance thereof consisting of Eligible Loans), the Retirement Account,
the Principal Account, the Interest Account and the Acquisition Fund, in that
order of priority, upon receipt of a Corporation certificate (which the
Corporation is required to provide on an annual basis) that any amounts to be
so transferred equal amounts which are subject to rebate to the United States
under Section 148 of the Code with respect to each series of Tax-Exempt
Notes.  In addition, the Trustee shall deposit to the credit of the Rebate
Account all investment earnings received on amounts in the Rebate Account.  In
determining the rebate amount, the Corporation and the Trustee shall take into
account all amounts held under the Indenture and, pending the application of
such amounts to the purpose for which such amounts were removed, all amounts
removed from under the Indenture.

                                     -148-
<PAGE>
 
     Moneys in the Rebate Account shall be paid by the Trustee to the United
States at such times and in such amounts as are necessary to comply with the
rebate provisions of Section 148 of the Code with respect to each series of
Tax-Exempt Notes.  In addition, upon receipt by the Trustee of a certification
of the Corporation that certain amounts in the Rebate Account are not subject
to rebate and an opinion of Bond Counsel to the effect that failure to rebate
such amounts will not cause interest on any series of Tax-Exempt Notes to
become includable in gross income of the owners thereof for federal income tax
purposes under either existing laws, regulations, rulings and decisions or any
then pending federal legislation, the Trustee shall transfer any such amounts
to the credit of the Revenue Fund. Moneys in the Rebate Account are not
available for transfer to any Fund or Account under the Indenture, except the
Revenue Fund under the circumstances described above, and shall be applied
solely to meet the Corporation's rebate obligations.

     Excess Earnings Account.  On or prior to each date established under the
Indenture for the calculation of Excess Earnings with respect to each series
of Tax-Exempt Notes (each an "Excess Earnings Computation Date"), the Trustee
and the Corporation shall determine whether any Excess Earnings have resulted
with respect to such series of Notes.  In this regard, a portion of the
proceeds of the Tax Exempt Series 1998-1 Notes will be applied to the purchase
of certain Eligible Loans previously financed with the proceeds of other bonds
or notes of the Original Issuer (the "Refunded Obligations"), thereby
refunding such bonds or notes.  Excess Earnings on such Eligible Loans shall
be the "Excess Earnings" computed with respect to the related series of
Refunded Obligations in accordance with the requirements of the indenture
relating to such series, all deposits to the Series 1998-1 Excess Earnings
Sub-Account in respect of Excess Earnings for each such series of Refunded
Obligations shall be applied to reduce the yield on the applicable Eligible
Loans in accordance with the requirements of the related indenture, and
amounts in respect of such Excess Earnings shall be deposited in, and shall be
applied from, the Series 1998-1 Excess Earnings Sub-Account prior to any other
deposits in, or applications from, the Excess Earnings Account.  The foregoing
provisions shall apply to each series of Refunded Obligations until such
series has been retired, after which time Excess Earnings on the applicable
Eligible Loans will be computed with respect to the Tax Exempt Series 1998-1
Notes.  The Corporation shall, upon each such calculation, furnish the Trustee
with a Corporation certificate verifying such calculation and with any
supporting documentation required to calculate or evidence the Excess Earnings
in accordance with applicable Treasury Regulations.  In the event any Excess
Earnings with respect to a series of Notes have resulted, the Trustee shall,
on or prior to such Excess Earnings Computation Date, transfer to the Excess
Earnings Account the amount, if any, which is necessary to increase the
balance in such Account to an amount equal to such Excess Earnings.  Any such
transfer shall be made from the Balances in the Revenue Fund, the Surplus Fund
(other than that portion of the Balance thereof consisting of Eligible Loans),
the Reserve Fund, the Administration Fund, the Surplus Fund (including any
portion of the Balance thereof consisting of Eligible Loans), the Retirement
Account, the Principal Account, the Interest Account and the Acquisition Fund,
in that order of priority.

     All amounts in the Excess Earnings Account, including all investment
earnings thereon, shall remain therein until transferred to the Revenue Fund
or paid by the Trustee to the United States Department of the Treasury or for
such other purpose as the Corporation may specify, upon receipt by the Trustee
of (a) a Corporation order directing the Trustee to so transfer or pay a
specified amount, and (b) a written opinion of Bond Counsel to the effect that
any such transfer or payment, upon satisfaction of any conditions set forth in
such opinion (e.g., forgiveness of indebtedness on all or a portion of the
related Financed Student Loans), would not cause interest on any series of
Tax-Exempt Notes to be includable in the gross income of any owners thereof
for federal income tax purposes.

     Amounts in the Excess Earnings Account shall be used only for the
purposes specified in the preceding paragraph, and shall not be available for
any other purpose, including, but not limited to, payment of Debt Service on
or the purchase price of the Notes or any Other Indenture Obligations.

                                     -149-
<PAGE>
 
     Surplus Fund

     The Indenture establishes a Surplus Fund, which is comprised of two
Accounts:  the Special Redemption and Prepayment Account and the Surplus
Account.  The Trustee shall deposit to the credit of the Surplus Fund Balances
in the Revenue Fund not required for deposit to any other Fund or Account.
Deposits to the Surplus Fund from the Revenue Fund shall be credited to the
Special Redemption and Prepayment Account to the extent the Balance thereof is
less than the Special Redemption and Prepayment Account Requirement for each
series of Notes, and otherwise to the Surplus Account.

     Balances in the Surplus Fund shall be applied to the following purposes
in the following order of priority:  first, to remedy deficiencies in the
Rebate Fund (after transfers thereto from the Revenue Fund); second, to remedy
deficiencies in the Interest Account (after transfers thereto from the Revenue
Fund) for the payment of interest on Senior Notes or Other Senior Obligations
payable therefrom; third, to remedy deficiencies in the Principal Account
(after transfers thereto from the Revenue Fund) for the call of Senior Notes
for redemption or the payment of principal or the purchase price of Senior
Notes or the payment of Other Senior Obligations payable therefrom; fourth, to
remedy deficiencies in the Retirement Account (after transfers thereto from
the Revenue Fund) for the call of Senior Notes for redemption or the payment
of Other Senior Obligations payable therefrom; fifth, to remedy deficiencies
in the Interest Account (after transfers thereto from the Revenue Fund) for
the payment of interest on Subordinate Notes or Other Subordinate Obligations
payable therefrom; sixth, to remedy deficiencies in the Principal Account
(after transfers thereto from the Revenue Fund) for the payment of the
principal at Stated Maturity or the purchase price of Subordinate Notes or the
payment of Other Subordinate Obligations payable therefrom; seventh, to remedy
deficiencies in the Retirement Account (after transfers thereto from the
Revenue Fund) for the call of Subordinate Notes for redemption or the payment
of Other Subordinate Obligations payable therefrom; eighth, to make deposits
(but only from the Surplus Account) to the credit of the Administration Fund
(after transfers thereto from the Revenue Fund) to the extent required
pursuant to a Corporation order for certain costs and expenses; ninth, to
remedy deficiencies in the Reserve Fund (to the extent that the Balance is
less than the Reserve Fund Requirement after transfers thereto from the
Revenue Fund); tenth, to remedy deficiencies in the Principal Account (after
transfers thereto from the Revenue Fund) to meet the sinking fund installment
with respect to the call of Subordinate Term Notes for redemption on a Sinking
Fund Payment Date; eleventh, to make transfers to the credit of the Retirement
Account to redeem Senior Notes or Subordinate Notes which are called for
redemption or to prepay Senior or Subordinate Notes as provided in a
Supplemental Indenture relating thereto (provided that any such transfers
shall be made only from Balances in the Special Redemption and Prepayment
Account); and twelfth, to make deposits (but only from the Surplus Account) to
the credit of the Interest Account for the payment of Carry-Over Amounts (and
accrued interest thereon).  Notwithstanding the foregoing, Balances in the
Surplus Fund consisting of Eligible Loans shall not be required to be applied
(1) pursuant to priorities first through seventh above until after any
transfers from the Reserve Fund have been taken into account, and (2) in any
event pursuant to priorities eighth through twelfth above. If the Surplus Fund
is to be used to make such transfers, transfers shall be made, first, from any
cash or Investment Securities included in the Surplus Account or the Special
Redemption and Prepayment Account, in that order, and, second, from the
proceeds of any sale of Student Loans included in the Surplus Account.

     Balances in the Special Redemption and Prepayment Account may also be
transferred to the Acquisition Fund for the acquisition or origination of
Eligible Loans as provided in the Indenture and as further authorized or
limited in a Supplemental Indenture.

     Subject to compliance with the provisions of the Indenture described
under "Call for Redemption, Prepayment or Purchase of Notes; Senior Asset
Requirement" above and satisfaction of certain other conditions set forth in
the Indenture, Balances in the Special Redemption and Prepayment Account
(other than any portion thereof to be applied to the mandatory prepayment of
principal of any Notes) may also be transferred to the Note Fund for the
purchase of Notes.

                                     -150-
<PAGE>
 
     Balances in the Surplus Account may, subject to satisfaction of certain
conditions set forth in the Indenture (including the requirement that, after
taking into account any such payments, the Senior Asset Requirement will be
met) also be applied, as determined by the Corporation from time to time, to
the payment of principal of or interest on Class C Notes when due or upon the
call for redemption thereof at the option of the Corporation.

     Subject to compliance with the provisions of the Indenture described
under "Call for Redemption, Prepayment or Purchase of Notes; Senior Asset
Requirement" above, Balances in the Surplus Account may also be applied to any
one or more of the following purposes at any time as determined by the
Corporation at such time, provided the Trustee shall have first certified that
no deficiencies exist at such time in the Note Fund, the Rebate Fund, the
Reserve Fund or the Special Redemption and Prepayment Account:

          (1)     transfer to the Retirement Account for the redemption
     of Senior Notes or Subordinate Notes called for redemption;

          (2)     transfer to the Principal Account or the Retirement
     Account for the purchase of Senior Notes or Subordinate Notes; or

          (3)     upon satisfaction of certain conditions set forth in
     the Indenture, (a) the acquisition of Student Loans meeting the
     requirements of clauses (A) (1) and (2) or (B) of the definition of
     "Eligible Loan" (see "Glossary of Certain Defined Terms"); (b) to
     reimburse another fund, account or other source of the Corporation
     for the previous payment of Costs of Issuance; and (c) for such
     other purposes as the Corporation shall determine; provided,
     however, that Balances in the Surplus Account shall not be applied
     to any of the purposes specified in the preceding clause (3)(b) or
     (c) or to the purchase of Student Loans that are not Eligible Loans
     unless, after taking into account any such application and
     excluding, for these purposes only, from the calculation of
     Aggregate Value, any Financed Student Loans which are not Eligible
     Loans and any moneys reasonably expected to be needed for transfer
     to the Rebate Fund or to be used to pay Costs of Issuance, Note
     Fees or Administrative Expenses, (i) the Senior Percentage will not
     be less than 112% (or such lower percentage specified in a
     Corporation certificate delivered to the Trustee which, if
     Unenhanced Senior Notes are Outstanding, shall not result in the
     lowering or withdrawal of the outstanding rating assigned by any
     Rating Agency to any of the Unenhanced Senior Notes Outstanding,
     or, if no Unenhanced Senior Notes are Outstanding but Other Senior
     Obligations are Outstanding, is acceptable to the Other Senior
     Beneficiaries entitled to such Other Senior Obligations), and (ii)
     the Subordinate Percentage will not be less than 102% (or such
     lower percentage specified in a Corporation certificate delivered
     to the Trustee which, if Unenhanced Subordinate Notes are
     Outstanding, shall not result in the lowering or withdrawal of the
     outstanding rating assigned by any Rating Agency to any of the
     Unenhanced Subordinate Notes Outstanding, or, if no Unenhanced
     Subordinate Notes are Outstanding but Other Subordinate Obligations
     are Outstanding, is acceptable to the Other Subordinate
     Beneficiaries entitled to such Other Subordinate Obligations); and
     provided, further, that Balances in the Surplus Account may be
     applied to the purchase of Eligible Loans as specified in the
     preceding clause (3)(a) without satisfying any other  condition of
     this clause (3), to the extent provided in a Supplemental Indenture
     (in this regard, the First Supplemental Indenture does not so
     provide with respect to the application of Balances in the Series
     1998-1 Tax Exempt and Taxable Surplus Sub-Accounts).

     The Trustee shall use its best efforts to sell Student Loans included in
the Balance of the Surplus Account at the best price available to the extent
necessary to make any transfer or payment therefrom described above.  In
addition, the Corporation may, at any time, sell to any purchaser (A) one or
more Eligible Loans Financed with moneys in the Surplus Account at a price not
less than 100% of the Principal Balance thereof plus accrued noncapitalized
interest thereon payable by the Eligible Borrower, or (B) one or more Student
Loans Financed with moneys in the Surplus Account that are not Eligible Loans
at a price not less than the lesser of 100% of the Principal Balance thereof
or the percentage of the Principal Balance thereof paid to finance such
Student Loan plus,

                                     -151-
<PAGE>
 
in either case, accrued noncapitalized interest thereon payable by the
Eligible Borrower.  Student Loans from time to time held in the Surplus
Account may also be purchased at any time with the proceeds of the
Corporation's bonds, notes or other evidences of indebtedness, at a purchase
price equal to 100% of the Principal Balance of the Student Loans so purchased
plus accrued noncapitalized interest thereon payable by the Eligible Borrower.
Any money received by the Corporation in connection with a sale of Financed
Student Loans pursuant to this paragraph shall be deposited to the credit of
the Surplus Account.

     Pending transfers from the Surplus Fund, the moneys therein shall be
invested in Investment Securities as described under "Investments" below, and
any earnings on or income from such investments shall be deposited in the
Revenue Fund.

PLEDGE; ENCUMBRANCES

     The Notes and all Other Indenture Obligations are special, limited
obligations of the Corporation specifically secured by the pledge of the
proceeds of the sale of Notes (until expended for the purpose for which the
Notes were issued), the Financed Student Loans and the revenues, moneys and
securities in the Acquisition Fund, the Note Fund, the Revenue Fund, the
Administration Fund, the Reserve Fund and the Surplus Fund, in the manner and
subject to the prior applications provided in the Indenture.  Financed Student
Loans purchased with the proceeds of the Corporation's bonds, notes or
obligations or sold to another purchaser, or resold to a Lender pursuant to
its repurchase obligation under a Student Loan Purchase Agreement, or sold or
exchanged for Eligible Loans in accordance with the provisions of the
Indenture, are, contemporaneously with receipt by the Trustee of the purchase
price thereof, including any Eligible Loans to be received in exchange
therefor, no longer pledged to nor serve as security for the payment of the
principal of, premium, if any, or interest on, or any Carry-Over Amounts (or
accrued interest thereon) with respect to the Notes or any Other Indenture
Obligations.  The revenues, moneys and securities in the Rebate Fund and the
proceeds thereof are not pledged to, and do not serve as security for, the
payment of the principal of, premium, if any, or interest on, any Carry-Over
Amounts (or accrued interest thereon) with respect to, or the purchase price
of, the Notes or any Other Indenture Obligations.

     The Corporation agrees that it will not create, or permit the creation
of, any pledge, lien, charge or encumbrance upon the Financed Student Loans or
the revenues and other moneys, securities, properties, rights, interests and
evidences of indebtedness pledged under the Indenture, except only as to a
lien subordinate to the lien of the Indenture created by any other indenture
authorizing the issuance of bonds, notes or other evidences of indebtedness of
the Corporation, the proceeds of which have been or will be used to refund or
otherwise retire all or a portion of the Outstanding Notes or as otherwise
provided in or permitted by the Indenture.  The Corporation agrees that it
will not issue any bonds or other evidences of indebtedness, other than the
Notes as permitted by the Indenture and other than Swap Agreements and Credit
Enhancement Facilities relating to Notes as permitted by the Indenture,
secured by a pledge of the revenues and other moneys, securities, properties,
rights, interests and evidences of indebtedness pledged under the Indenture or
held aside by the Corporation or by a fiduciary under the Indenture, creating
a lien or charge on such revenues and other moneys, securities, properties,
rights, interests and evidences of indebtedness equal or superior to the lien
of the Indenture; provided that nothing in the Indenture is intended to
prevent the Corporation from issuing obligations secured by assets and
revenues of the Corporation other than the revenues and other moneys,
securities, properties, rights, interests and evidences of indebtedness
pledged in the Indenture.

COVENANTS

     Certain covenants with the Holders of the Notes and Other Beneficiaries
contained in the Indenture are summarized as follows:

                                     -152-
<PAGE>
 
     Trustee to Hold Financed Student Loans.  The Corporation shall cause all
Financed Student Loans to be endorsed and otherwise conveyed to the Trustee on
behalf of the Corporation in accordance with the provisions of the applicable
Student Loan Purchase Agreement or, in the case of any origination of Financed
Student Loans, shall cause such Student Loans to be originated in the name of
the Trustee.  The Trustee shall be the legal owner of all Financed Student
Loans for all purposes of the Higher Education Act and each Guarantee
Program.  The Trustee shall so hold such Financed Student Loans in its
capacity as trustee pursuant to the Indenture and, in such capacity, shall be
acting on behalf of the Corporation, as the beneficial owner of such Student
Loans, as well as the Holders of the Notes and all Other Beneficiaries, as
their interests may appear.

     Enforcement and Amendment of Guarantee Agreements.  So long as any Notes
or Other Indenture Obligations are Outstanding and Financed Eligible Loans are
Guaranteed by a Guarantee Agency, the Corporation agrees that it (1) will,
from and after the date on which the Trustee on its behalf shall have entered
into the Guarantee Agreement, cause the Trustee to maintain the same and
diligently enforce the Trustee's rights thereunder, (2) will cause the Trustee
to enter into such other similar or supplemental agreements as shall be
required to maintain benefits for all Financed Student Loans covered thereby,
and (3) will not consent to or permit any rescission of or consent to any
amendment to or otherwise take any action under or in connection with the same
which in any manner will materially adversely affect the rights of the
Noteholders or Other Beneficiaries under the Indenture.

     Acquisition, Collection and Assignment of Student Loans.  The Corporation
agrees that it will, except as provided with regard to the Surplus Fund (see
"Funds and Accounts -- Surplus Fund" above), cause the Trustee to originate or
acquire only Eligible Loans with moneys in any of the Funds and (subject to
any adjustments referred to in the following paragraph) shall diligently cause
to be collected all principal and interest payments on all the Financed
Student Loans and other sums to which the Corporation is entitled pursuant to
any Student Loan Purchase Agreement, and all grants, subsidies, donations,
insurance payments, Special Allowance Payments and all defaulted payments
Guaranteed by any Guarantee Agency which relate to such Financed Student
Loans.  The Corporation shall also make, or cause to be made by Lenders or
Servicers, every effort to perfect the Corporation's, the Trustee's or such
Lender's or Servicer's claims for payment from the Secretary of Education or a
Guarantee Agency, as soon as possible, of all payments related to such
Financed Student Loans.  The Corporation will cause the Trustee to assign such
Financed Student Loans for payment of guarantee or insurance benefits within
the time required under applicable law and regulations.  The Corporation will
cause all United States and State statutes, rules and regulations which apply
to the Program and to Financed Student Loans to be complied with.

     Enforcement of Financed Student Loans.  The Corporation agrees that it
shall cause to be diligently enforced, and cause to be taken all steps,
actions and proceedings reasonably necessary for the enforcement of, all
terms, covenants and conditions of all Financed Student Loans and agreements
in connection therewith, including the prompt payment of all principal and
interest payments (as such payments may be adjusted to take into account (i)
any discount the Corporation may cause to be made available to borrowers who
make payments on Financed Student Loans through automatic withdrawals, and
(ii) any reduction in the interest payable on Financed Student Loans provided
for in any special program under which such loans were originated) and all
other amounts due the Corporation or the Trustee thereunder.  Nothing in the
provisions of the Indenture described in this paragraph, however, shall be
construed to prevent the Corporation from settling a default or curing a
delinquency on any Financed Student Loan on such terms as shall be required by
law.  In addition, (1) the Corporation may cause the Trustee to forgive the
indebtedness on all or a portion of the Financed Student Loans or take such
other action as may be provided in the written opinion of Bond Counsel, as
provided in the Indenture, to the extent necessary to prevent interest on any
series of Tax-Exempt Notes from being includable in the gross income of the
owners thereof for federal income tax purposes, and may cause the Trustee to
forgive the remaining indebtedness on any Financed Student Loan having a
principal balance not in excess of $100 if, in the reasonable judgment of the
Corporation, the cost of collection of the remaining indebtedness of such
Financed Student Loan would exceed such remaining indebtedness, and (2) the
Corporation may cause the Trustee to amend the terms of a Financed Student
Loan to provide for a different rate of interest thereon to the extent
required by law or, if such Financed Student Loan is a Plus or SLS Loan, to
effect a reissuance of such Plus or SLS Loan at a variable rate.

                                     -153-
<PAGE>
 
     Servicing and Other Agreements.  The Corporation may contract with other
Persons to assist it in performing its duties under the Indenture, and any
performance of such duties by a Person so identified to the Trustee shall be
deemed to be action taken by the Corporation.  The Corporation may, and prior
to or contemporaneously with the Section 150(d)(3) Transfer shall, enter into
a Servicing Agreement providing for the servicing of the Financed Student
Loans and performance of certain of its other obligations under the Indenture.

     Administration and Collection of Financed Student Loans.  The Corporation
agrees that all Financed Student Loans shall be administered and collected
either by the Corporation or by a Servicer selected by the Corporation (and,
after the Section 150(d)(3) Transfer, shall be so administered and collected
by a Servicer) in a competent, diligent and orderly fashion and in accordance
with all requirements of the Higher Education Act, the Secretary of Education,
the Indenture, the Contract of Insurance, the Federal Reimbursement Contracts,
each Guarantee Program and each Guarantee Agreement.

     Books of Account, Annual Audit.  The Corporation agrees that it will
cause to be kept and maintained proper books of account relating to the
Program in which full, true and correct entries will be made, in accordance
with generally accepted accounting principles, of all dealings or transactions
of or in relation to the business and affairs of the Corporation, and within
120 days after the end of each Fiscal Year will cause such books of account to
be audited by an Accountant.  A copy of each audit report, annual balance
sheet and income and expense statement showing in reasonable detail the
financial condition of the Corporation as at the close of each Fiscal Year,
and summarizing in reasonable detail the income and expenses for such year,
including the transactions relating to the Funds and Accounts, shall be filed
promptly with the Trustee and be available for inspection by any Noteholder or
Other Beneficiary.

     Punctual Payments.  The Corporation agrees that it will duly and
punctually pay, or cause to be paid, the principal of, premium, if any, and
interest on and any Carry-Over Amount (and accrued interest thereon) with
respect to each and every Note and each Other Indenture Obligation from the
revenues and other assets pledged under the Indenture on the dates and at the
places, and in the manner provided, in the Notes and with respect to each
Other Indenture Obligation according to the true intent and meaning thereof,
and the Corporation will faithfully do and perform and at all times fully
observe and keep any and all of its covenants, undertakings, stipulations and
provisions contained in the Notes, the Other Indenture Obligations and the
Indenture.

     Monthly Servicing Reports.  The Corporation shall prepare, or cause a
Servicer to prepare, a Monthly Servicing Report for each calendar month and
shall furnish, or cause to be furnished, to the Trustee a copy of each such
report by the 25th day of the next calendar month (or the next succeeding
Business Day if such 25th day is not a Business Day).

     Tax Covenant.  The Corporation covenants that (a) it will not take or
omit to take any action which may render the interest on any Tax-Exempt Notes
includable in gross income for purposes of federal income taxation, (b) it
will use the proceeds of the Notes and any other funds of the Corporation in
such a manner that the use thereof would not cause the Tax-Exempt Notes to be
"arbitrage bonds" under Section 148 of the Code, and (c) it will not permit at
any time any proceeds of the Notes or any other funds of the Corporation to be
used, directly or indirectly, in a manner which would result in the inclusion
of the interest on any Tax-Exempt Note in gross income for purposes of federal
income taxation otherwise afforded by the Code.

     THE FIRST SUPPLEMENTAL INDENTURE PROHIBITS ANY OBLIGOR ON A STUDENT LOAN
FINANCED, IN WHOLE OR IN PART, WITH PROCEEDS OF THE TAX EXEMPT SERIES 1998-1
NOTES, OR ANY RELATED PARTY TO SUCH OBLIGOR, FROM PURCHASING ANY TAX EXEMPT
SERIES 1998-1 NOTES IN AN AMOUNT RELATED TO THE AMOUNT OF SUCH STUDENT LOAN.

     Limitation on Administrative Expenses and Note Fees.  The Corporation
covenants and agrees that the Administrative Expenses and Note Fees will not,
in any Fiscal Year, exceed those that are reasonable and necessary in light of
all circumstances then existing and will not, in any event, be in such amounts
as will materially adversely affect the ability of the Corporation to pay or
perform, as the case may be, any of its obligations under the Indenture

                                     -154-

or the security for any Beneficiaries.  The Corporation further covenants in
the First Supplemental Indenture that the Costs of Issuance, Administrative
Expenses and Note Fees to be paid, or reimbursed to the Corporation, from the
Administration Fund will not exceed the aggregate amount thereof specified in
the Closing Cash Flow Projection, unless the Corporation satisfies certain
conditions, including confirmation from each of the Rating Agencies then
rating the Series 1998-1 Notes that payment or reimbursement of such
additional Costs of Issuance, Administrative Expenses or Note Fees will not
result in a reduction or withdrawal of the rating of the Series 1998-1 Notes.

     Amendment of Student Loan Purchase Agreements.  The Corporation shall
notify the Trustee in writing of any proposed amendments to the Student Loan
Purchase Agreements.  No such amendment shall become effective unless and
until the Trustee consents in writing thereto, which consent shall not be
given unless the Trustee receives an opinion of Counsel that such amendment is
required by the Higher Education Act or is not to the prejudice of the Holders
of the Notes or Other Beneficiaries.

     Amendment of Remarketing Agreements and Depositary Agreements.  The
Corporation shall notify the Trustee and any related Credit Facility Provider
in writing of any proposed amendments to any Remarketing Agreement or
Depositary Agreement.  No such amendment shall become effective unless and
until (1) the Trustee consents in writing thereto, which consent shall not be
given unless the Trustee receives an opinion of Counsel that such amendment is
required by a Credit Enhancement Facility or the Indenture or is not to the
material prejudice of the Holders of the Notes, and (2) any related Credit
Facility Provider consents in writing thereto, which consent shall not be
unreasonably withheld, provided that no consent of the Credit Facility
Provider shall be required if the Credit Facility Provider receives an opinion
of Counsel that such amendment is required by the Indenture.

     Credit Enhancement Facilities and Swap Agreements.  The Corporation may
from time to time enter into or obtain the benefit of any Credit Enhancement
Facilities or Swap Agreements with respect to any Notes of any series;
provided that a Supplemental Indenture is entered into authorizing the
execution and delivery of such agreement.  (See "Supplemental Indentures"
below.)

     No Supplemental Indenture shall authorize the execution of a Swap
Agreement unless, as of the date the Corporation enters into such Swap
Agreement, the Swap Counterparty has outstanding obligations rated by each
Rating Agency not lower than in its third highest Specific Rating Category (or
each Rating Agency has a comparable other rating with respect to such Swap
Counterparty, such as a comparable rating of claims paying ability or
deposits).  No such Swap Agreement shall be designated as a Senior Swap
Agreement unless, as of the date the Corporation enters into such Swap
Agreement, the Senior Asset Requirement will be met and the Trustee shall have
received written confirmation from each Rating Agency that the execution and
delivery of the Swap Agreement will not cause the reduction or withdrawal of
any rating or ratings then applicable to any Outstanding Unenhanced Notes.

     Any Supplemental Indenture authorizing the execution by the Corporation
of a Swap Agreement or Credit Enhancement Facility may include provisions with
respect to the application and use of all amounts to be paid thereunder.  No
amounts paid under any such Credit Enhancement Facility will be part of the
Trust Estate except to the extent, if any, specifically provided in such
Supplemental Indenture and no Beneficiary shall have any rights with respect
to any such amounts so paid except as may be specifically provided in such
Supplemental Indenture.

NO PETITION

     The Trustee, by entering into the Indenture, and each Noteholder, by
accepting a Note, covenants and agrees that it will not at any time institute
against the Corporation, or join in any institution against the Corporation
of, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings, or other proceedings under any United States Federal or state
bankruptcy or similar law in connection with any obligations relating to the
Notes or the Indenture.

     investment as an Investment Security will not cause any rating then
     applicable to any Outstanding Unenhanced Notes to be lowered or
     withdrawn or, if no Unenhanced Notes are then Outstanding but Other
     Indenture Obligations are Outstanding, is acceptable to the Other
     Beneficiaries entitled to such Other Indenture Obligations, as
     evidenced in writing to the trustee by each such Other Beneficiary.

REPORTS TO NOTEHOLDERS

     The Trustee, in accordance with the Indenture, is required to mail a copy
of each Monthly Servicing Report to each Noteholder of record as of the most
recent Record Date.  In addition, beneficial owners of the Notes may receive
such reports, upon written request to the Trustee together with a
certification that they are beneficial owners of the Notes.  In the case of
the Series 1998-1 Notes, the Servicer will file a copy of each such report
with the Commission on Form 8-K.  However, in accordance with the Exchange Act
and the rules and regulations of the Commission thereunder, the Corporation
expects that it's obligation to file such reports will be terminated after
June 30, 1998.

     If any of the following events occur, it is an "Event of Default" under
the Indenture:

          (A)     default in the due and punctual payment of any
     interest on any Senior Note; or

          (B)     default in the due and punctual payment of the

          (E)     if no Senior Obligations are Outstanding, default in
     the due and punctual payment of any interest on any Subordinate
     Note; or

          (F)     if no Senior Obligations are Outstanding, default in
     the due and punctual payment of the principal of, or premium, if

     thereof, at the date fixed for redemption thereof (including, but
     not limited to, Sinking Fund Payment Dates) or otherwise upon the
     maturity thereof; or

<PAGE>
 
          (J)     if no Senior Obligations or Subordinate Obligations
     are Outstanding, default in the due and punctual payment of the
     principal of, or premium, if any, on, any Class C Note, whether at
     the Stated Maturity thereof, at the date fixed for redemption
     thereof (including, but not limited to, Sinking Fund Payment Dates)
     or otherwise upon the maturity thereof; or

          (K)     default in the performance of any of the Corporation's

     the Trustee to the Corporation, which may give such notice in its
     discretion and shall give such notice at the written request of the
     Acting Beneficiaries Upon Default, or by the Holders of not less
     than 10% in aggregate Principal Amount of the Outstanding Notes to
     the Corporation and the Trustee, provided that, except with respect
     to the Corporation's covenants relating to the tax exemption of
     interest on any Tax-Exempt Notes, if the default is such that it
     can be corrected, but not within such 30 days, it shall not
     constitute an Event of Default if corrective action is instituted
     by the Corporation within such 30 days and is diligently pursued
     until the default is corrected; or

          (M)     certain events of bankruptcy or insolvency of the
     Corporation.

REMEDIES

     Whenever any Event of Default other than that described in paragraph (L)
under "Events of Default" above shall have occurred and be continuing, the
Trustee may (and, upon the written request of the Acting Beneficiaries Upon
Default, the Trustee shall), by notice in writing delivered to the
Corporation, declare the principal of and interest accrued on all Notes then
Outstanding due and payable.

     Whenever any Event of Default described in paragraph (L) under "Events of

shall, upon the written request of the Acting Beneficiaries Upon Default, by
notice in writing delivered to the Corporation, declare the principal of and
interest on all Notes then Outstanding due and payable.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee, the Acting Beneficiaries Upon Default, by written notice to the
Corporation and the Trustee, may rescind and annul such declaration and its
consequences if:

     (1)     There has been paid to or deposited with the Trustee by or for
the account of the Corporation, or provision satisfactory to the Trustee has
been made for the payment of, a sum sufficient to pay:

          (A)     if Senior Notes or Other Senior Obligations are
     Outstanding:  (i) all overdue installments of interest on all
     Senior Notes; (ii) the principal of (and premium, if any, on) any
     Senior Notes which have become due other than by such declaration
     of acceleration, together with interest thereon at the rate or
     rates borne by such Senior Notes; (iii) to the extent that payment
     of such interest is lawful, interest upon overdue installments of
     interest on the Senior Notes at the rate or rates borne by such
     Senior Notes; (iv) all Other Senior Obligations which have become
     due other than as a direct result of such declaration of
     acceleration; (v) all other sums required to be paid to satisfy the
     Corporation's obligations with respect to the transmittal of moneys
     to be credited to the Revenue Fund, the Rebate Fund, the
     Acquisition Fund and the Interest

                                     -158-
<PAGE>
 
     Account under the provisions of the Indenture; and (vi) all sums paid or
     advanced by the Trustee under the Indenture and the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel and any Paying Agents, Deposit Agents, Remarketing
     Agents, Depositaries, Auction Agents and Broker-Dealers; or

          (B)     if no Senior Obligations are Outstanding, but
     Subordinate Notes or Other Subordinate Obligations are Outstanding:
     (i) all overdue installments of interest on all Subordinate Notes;
     (ii) the principal of (and premium, if any, on) any Subordinate
     Notes which have become due other than by such declaration of

     of such interest is lawful, interest upon overdue installments of
     interest on the Subordinate Notes at the rate or rates borne by
     such Subordinate Notes; (iv) all Other Subordinate Obligations
     which have become due other than as a direct result of such
     declaration of acceleration; (v) all other sums required to be paid
     to satisfy the Corporation's obligations with respect to the
     transmittal of moneys to be credited to the Revenue Fund, the
     Rebate Fund, the Acquisition Fund and the Interest Account under
     the provisions of the Indenture; and (vi) all sums paid or advanced
     by the Trustee under the Indenture and the reasonable compensation,
     expenses, disbursements and advances of the Trustee, its agents and
     counsel and any Paying Agents, Deposit Agents, Remarketing Agents,
     Depositaries, Auction Agents and Broker-Dealers; or

          (C)     if no Senior Obligations or Subordinate Obligations
     are Outstanding:  (i) all overdue installments of interest on all
     Class C Notes and all overdue sinking fund installments for the
     retirement of Class C Notes; (ii) the principal of (and premium, if
     any, on) any Class C Notes which have become due otherwise than by
     such declaration of acceleration and interest thereon at the rate
     or rates borne by such Class C Notes; (iii) to the extent that
     payment of such interest is lawful, interest upon overdue
     installments of interest on the Class C Notes at the rate or rates
     borne by such Class C Notes; (iv) all other sums required to be
     paid to satisfy the Corporation's obligations with respect to the
     transmittal of moneys to be credited to the Revenue Fund, the

     Indenture; and (v) all sums paid or advanced by the Trustee under
     the Indenture and the reasonable compensation, expenses,

     and any Paying Agents, Deposit Agents, Remarketing Agents,
     Depositaries, Auction Agents and Broker-Dealers; and

     (2)     All Events of Default, other than the nonpayment of the principal
of and interest on Notes or amounts owing to Other Beneficiaries which have
become due solely by such declaration of acceleration, have been cured or
waived as provided in the Indenture.

     If an Event of Default has occurred and is continuing, the Trustee may,
subject to applicable law, pursue any available remedy by suit at law or in
equity to enforce the covenants of the Corporation in the Indenture and may
pursue such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce, or aid in the protection and enforcement of,
the covenants and agreements in the Indenture.  The Trustee is also authorized
to file proofs of claims in any equity, receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization or other similar proceedings.

     Notwithstanding any other provisions of the Indenture, if an "Event of
Default" (as defined therein) occurs under a Swap Agreement or a Credit
Enhancement Facility and, as a result, the Other Beneficiary that is a party
thereto is entitled to exercise one or more remedies thereunder, such Other
Beneficiary may exercise such remedies, including, without limitation, the
termination of such agreement, as provided therein, in its own discretion;
provided that the exercise of any such remedy does not adversely affect the
legal ability of the Trustee or Acting Beneficiaries Upon Default to exercise
any remedy available under the Indenture.

     If an Event of Default has occurred and is continuing, and if it shall
have been requested so to do by the Holders of not less than 25% in aggregate
Principal Amount of all Notes then Outstanding or any Other Beneficiary and
shall have been indemnified as provided in the Indenture, the Trustee is
obliged to exercise such one or more

                                     -159-
<PAGE>
 
of the rights and powers conferred by the Indenture as the Trustee, being
advised by its counsel, shall deem most expedient in the interests of the
Beneficiaries; provided, however, that the Trustee has the right to decline to
comply with any such request if the Trustee shall be advised by Counsel that
the action so requested may not lawfully be taken or if the Trustee receives,
before exercising such right or power, contrary instructions from the Holders
of not less than a majority in aggregate Principal Amount of the Notes then
Outstanding or from any Other Beneficiary.

     The Acting Beneficiaries Upon Default have the right, at any time, by an
instrument or instruments in writing executed and delivered to the Trustee, to
direct the method and place of conducting all proceedings to be taken in
connection with the enforcement of the terms and conditions of the Indenture;
provided that (a) such direction shall not be otherwise than in accordance
with the provisions of law and of the Indenture; (b) the Trustee shall not
determine that the action so directed would be unjustly prejudicial to the
Holders of Notes or Other Beneficiaries not taking part in such direction,
other than by effect of the subordination of any of their interests
thereunder; and (c) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

     Except as may be permitted in a Supplemental Indenture with respect to an
Other Beneficiary, no Holder of any Note or Other Beneficiary shall have any
right to institute any suit, action or proceeding in equity or at law for the
enforcement of the Indenture or for the execution of any trust under the
Indenture or for the appointment of a receiver or any other remedy under the
Indenture unless (1) an Event of Default shall have occurred and be
continuing, (2) the Holders of not less than 25% in aggregate Principal Amount
of Notes then Outstanding or any Other Beneficiary shall have made written
request to the Trustee, (3) such Beneficiary or Beneficiaries shall have
offered to the Trustee indemnity, (4) the Trustee shall have thereafter failed
for a period of 60 days after the receipt of the request and indemnification
or refused to exercise the powers granted in the Indenture or to institute
such action, suit or proceeding in its own name and (5) no direction
inconsistent with such written request shall have been given to the Trustee
during such 60-day period by the Holders of not less than a majority in
aggregate Principal Amount of the Notes then Outstanding or by any Other
Beneficiary; provided, however, that, notwithstanding the foregoing provisions
of the Indenture, the Acting Beneficiaries Upon Default may institute any such
suit, action or proceeding in their own names for the benefit of the Holders
of all Outstanding Notes and Other Beneficiaries under the Indenture.

     The Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of, premium, if any, and
interest on such Note in accordance with the terms thereof and of the
Indenture and, upon the occurrence of an Event of Default with respect
thereto, to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder.

     The Trustee, unless it has declared the principal of and interest on all
Outstanding Notes immediately due and payable and a judgment or decree for
payment of the money due has been obtained by the Trustee, must waive any
Event of Default and its consequences upon written request of the Acting
Beneficiaries Upon Default; provided, however, that there shall not be waived
(a) any Event of Default arising from the acceleration of the maturity of the
Notes, except upon the rescission and annulment of such declaration as
described in the third paragraph under this caption "Remedies"; (b) any Event
of Default in the payment when due of any amount owed to any Beneficiary
(including payment of principal of or interest on any Note) except with the
consent of such Beneficiary or unless, prior to such waiver, the Corporation
has paid or deposited (or caused to be paid or deposited) with the Trustee a
sum sufficient to pay all amounts owed to such Beneficiary (including to the
extent permitted by law, interest upon overdue installments of interest); (c)
any Event of Default arising from the failure of the Corporation to pay unpaid
expenses of the Trustee, its agents and counsel, and any Authenticating Agent,
Paying Agents, Note Registrars, Deposit Agents, Remarketing Agents,
Depositaries, Auction Agents and Broker-Dealers as required by the Indenture,
unless, prior to such waiver, the Corporation has paid or deposited (or caused
to be paid or deposited) with the Trustee sums required to satisfy such
obligations of the Corporation under the provisions of the Indenture.

APPLICATION OF PROCEEDS

     All moneys received by the Trustee pursuant to any remedy shall, after
payment of the cost and expenses of the proceedings resulting in the
collection of such moneys and of the expenses, liabilities and advances
incurred or made by the Trustee with respect thereto, be applied as follows:

          (A) Unless the principal of all the Outstanding Notes shall
     have become or shall have been declared due and payable, all such
     moneys shall be applied as follows:

          installments of principal and interest then due on the Senior
          Notes and all Other Senior Obligations, and if the amount
          available shall not be sufficient to pay all such amounts in
          full, then to the payment ratably, in proportion to the
          amounts due, to the Senior Noteholders and to each Other
          Senior Beneficiary, without any discrimination or preference,

          thereafter to the payment of principal;

          of all installments of principal and interest then due on the
          Subordinate Notes and all Other Subordinate Obligations, and
          if the amount available shall not be sufficient to pay all
          such amounts in full, then to the payment ratably, in
          proportion to the amounts due, without regard to due date, to
          the Subordinate Noteholders and to each Other Subordinate
          Beneficiary, without any discrimination or preference, and the
          Trustee shall apply the amount so apportioned to the
          Subordinate Noteholders first to the payment of interest and
          thereafter to the payment of principal; and

               THIRD, to the payment of the Holders of the Class C Notes
          of all installments of principal and interest (other than
          interest on overdue principal) then due and payable.

          (B)     If the principal of all Outstanding Notes shall have
     become due or shall have been declared due and payable and such
     declaration has not been annulled and rescinded under the
     provisions of the Indenture, all such moneys shall be applied as
     follows:

               FIRST, to the payment to the Senior Beneficiaries of all
          principal and interest then due on the Senior Notes and all
          Other Senior Obligations, without preference or priority of
          principal over interest or of interest over principal, or of
          any installment of interest over any other installment of
          interest, or of any Senior Beneficiary over any other Senior
          Beneficiary, ratably, according to the amounts due, to the
          Persons entitled thereto without any discrimination or
          preference; and

               SECOND, to the payment to the Subordinate Beneficiaries
          of the principal and interest then due on the Subordinate
          Notes and all Other Subordinate Obligations, without
          preference or priority of principal over interest or of
          interest over principal, or of any installment of interest
          over any other installment of interest, or of any Subordinate
          Beneficiary over any other Subordinate Beneficiary, ratably,
          according to the amounts due, to the Persons entitled thereto
          without any discrimination or preference, and

               THIRD, to the payment of the principal and premium, if
          any, and interest then due and unpaid upon the Class C Notes,
          without preference or priority of principal over interest or
          of interest over principal, or of any installment of interest
          over any other installment of interest, or of any Class C Note
          over any other Class C Note, ratably, according to the amounts
          due respectively for principal and interest, and other amounts
          owing, to the Persons entitled thereto without any
          discrimination or preference.

                                     -161-

          (C)     If the principal of all Outstanding Notes shall have
    been declared due and payable and if such declaration shall
    thereafter have been rescinded and annulled, then (subject to the
    provisions described in paragraph (B) above, in the event that the
    principal of all the Outstanding Notes shall later become or be
    declared due and payable) the money held by the Trustee under the
    Indenture shall be applied in accordance with the provisions
    described in paragraph (A) above.

TRUSTEE

     Prior to the occurrence of an Event of Default which has not been cured,
the Trustee is required to perform such duties and only such duties as are
specifically set forth in the Indenture.  Upon the occurrence and continuation
of an Event of Default, the Trustee shall exercise the rights and powers
vested in it by Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in
his own affairs.

     Before taking any action under the Indenture, the Trustee may require
that satisfactory indemnity be furnished to it for the reimbursement of all
expenses to which it may be put and to protect it against all liability by
reason of any action so taken, except liability which is adjudicated to have
resulted from its negligence or willful misconduct.

     The Trustee may at any time resign upon 60 days' notice to the
Corporation and to the Beneficiaries, such resignation to take effect upon the
appointment of a successor Trustee.  The Trustee may be removed at any time by
the Corporation at the request of the Holders of a majority in Principal
Amount of Notes Outstanding, except during the existence of an Event of
Default.  No such removal shall be effective until the appointment of a
successor Trustee.

DEPOSIT AGENTS

     The Corporation may, in a Supplemental Indenture, appoint one or more
Deposit Agents to hold any part or all of the Revenue Fund, the Acquisition
Fund and/or the Administration Fund.  Pursuant to the First Supplemental
Indenture, Norwest Bank of South Dakota, N.A., Sioux Falls, South Dakota, has
been appointed a Deposit Agent for the Revenue Fund.  Any Deposit Agent may be
removed at any time by the Corporation by Board Resolution and by instrument
signed by an Authorized Officer of the Corporation filed with such Deposit
Agent.

     Each Deposit Agent appointed by the Corporation shall be an incorporated
bank having trust powers or trust company organized under the laws of the
State, or a national banking association having trust powers, having its
principal office in the State and having a combined capital and surplus of at
least $5,000,000.

SUPPLEMENTAL INDENTURES

     Supplemental Indentures Not Requiring Consent of Beneficiaries

     The Corporation and the Trustee may, from time to time and at any time,
without the consent of, or notice to, any of the Noteholders or any Other
Beneficiary (except to the extent, if any, required pursuant to a Supplemental
Indenture authorizing the issuance of a series of Notes), enter into an
indenture or indentures supplemental to the Indenture as shall not be
inconsistent with the terms and provisions of the Indenture, so as to thereby,
among other things:

          (a)     cure any ambiguity or formal defect or omission in the
     Indenture or in any Supplemental Indenture,

                                     -162-

          (b)     grant to or confer upon the Trustee for the benefit of
     the Beneficiaries any additional rights, remedies, powers,
     authority or security that may lawfully be granted to or conferred
     upon the Beneficiaries or the Trustee,

          (c)     describe or identify more precisely any part of the
     Trust Estate or subject additional revenues, properties or
     collateral to the lien and pledge of the Indenture,

          (d)     authorize the issuance of a series of Notes, subject
     to the requirements of the Indenture (see "Additional Notes"

     "Cash Flow Projection",

          (f)     modify the Indenture as required by any Credit
     Facility Provider or Swap Counterparty, or otherwise necessary to
     give effect to any Credit Enhancement Facility or Swap Agreement,
     at the time of issuance of a series of Notes to which such
     agreements relate; provided that no such modifications shall be
     effective (1) if the consent of any Noteholders would be required
     therefor under the proviso described in the next succeeding
     paragraph and such consent has not been obtained, or (2) the
     Trustee shall determine that such modifications are to the
     prejudice of any Class C Noteholder, or

          (g)     make any other change in the Indenture which, in the
     judgment of the Trustee, is not to the prejudice of the Trustee or
     any Beneficiary.

     Supplemental Indentures Requiring Consent of Noteholders

     Exclusive of Supplemental Indentures described in the preceding
paragraph, the Trustee, upon receipt of an instrument evidencing the consent

theretofore provided in the Indenture, (g) the surrendering of a privilege or
a priority granted by the Indenture if, in the judgment of the Trustee, to the
detriment of another Beneficiary under the Indenture, (h) a reduction or an
increase in the aggregate Principal Amount of the Notes required for consent
to such Supplemental Indenture, (i) the creation of any lien ranking prior to

Beneficiary that has provided a Credit Enhancement Facility or Swap Agreement
of such class.

     Rights of Trustee

     If, in the opinion of the Trustee, any Supplemental Indenture adversely
affects the rights, duties or immunities of the Trustee under the Indenture or
otherwise, the Trustee may, in its discretion, decline to execute such
Supplemental Indenture.  The Trustee is entitled to receive, and shall be
fully protected in relying upon, an opinion of its Counsel as conclusive
evidence that any such Supplemental Indenture conforms to the requirements of
the Indenture.

     Consent of Depositaries, Remarketing Agents, Auction Agents and
     Broker-Dealers

Agreement or Broker-Dealer Agreement is in effect, no Supplemental Indenture
which materially adversely affects the rights, duties or immunities of the
Depositary, the Remarketing Agent, the Auction Agent or the Broker-Dealer, as
the case may be, created by the Indenture or the Depositary Agreement,
Remarketing Agreement, Auction Agent Agreement or Broker-Dealer Agreement, as
appropriate, shall become effective unless and until delivery to the Trustee
of a written consent of the Depositary, the Remarketing Agent, the Auction
Agent or the Broker-Dealer, as the case may be, to such Supplemental
Indenture.

     Opinion and Rating Agency Approval Required Prior to Execution of
     Supplemental Indenture

     No Supplemental Indenture shall be executed unless, prior to the
execution thereof: (1) if any Tax-Exempt Notes are Outstanding, the
Corporation shall have provided to the Trustee an opinion of Bond Counsel to
the effect that the execution and delivery of such Supplemental Indenture will
not adversely affect the exclusion from the gross income of the owners thereof
for federal income tax purposes of interest on any such Tax-Exempt Notes; and
(2) the Trustee shall have received written evidence from each Rating Agency
that execution and delivery of such Supplemental Indenture will not adversely
affect any rating or ratings then applicable to any of the Outstanding Notes.

DISCHARGE OF NOTES AND INDENTURE

     The obligations of the Corporation under the Indenture, and the liens,
pledges, charges, trusts, covenants and agreements of the Corporation therein
made or provided for, shall be fully discharged and satisfied as to any Note
and such Note shall no longer be deemed to be Outstanding thereunder:

          (i)     when such Note shall have been canceled, or shall have
     been purchased by the Trustee from moneys held by it under the
     Indenture; or

          (ii)    as to any Note not canceled or so purchased, when
     payment of the principal of and the applicable redemption premium,

     exclusively for such payment, (1) moneys sufficient to make such
     payment or (2) Government Obligations maturing as to principal and
     interest in such amount and at such times as will ensure the
     availability of sufficient moneys to make such payment and, if
     payment of all then Outstanding Notes is to be so provided for, all
     payments required to be made to the United States Treasury or
     otherwise with respect to Rebate Amounts and Excess Earnings, as
     well as the fees and expenses of the Trustee and any other
     fiduciaries under the Indenture.

     Notwithstanding the provisions of the Indenture just described, no Notes
shall be defeased unless, after giving effect to the defeasance, the
requirements in the Indenture described under "Call for Redemption, Prepayment
or Purchase of Notes; Senior Asset Requirement" above are met as if such Notes
were to be called for redemption on the date such Notes are to be defeased.

NOTICES TO NOTEHOLDERS

     Except as is otherwise provided in the Indenture, any provision in the
Indenture for the mailing of notice or other instrument to Holders of Notes
will be fully complied with if it is mailed by first-class mail, postage
prepaid, to each Holder of Notes outstanding at the address appearing on the
Note Register.  In addition, whenever notice is to be mailed under the
Indenture to the Holders of Notes, the Trustee is also, upon request, to mail
a copy of such notice to (1) any Holder of at least $1,000,000 in aggregate
Principal Amount of the Notes (or, in the event less than $1,000,000 in
aggregate Principal Amount of Notes is outstanding, the Holder of all
outstanding Notes), in addition to the copy mailed to such Holder's address
appearing on the Note Register, at such other address as such Holder shall

Facility by reason of which such Person is an Other Beneficiary.


                              TAX MATTERS

TAX EXEMPT SERIES 1998-1 NOTES

     In the opinion of Dorsey & Whitney LLP, as Bond Counsel, under laws,
regulations, rulings and decisions in effect on the Date of Issuance of the
Series 1998-1 Notes, interest on the Tax Exempt Series 1998-1 Notes is not
includable in gross income of the owners thereof for federal income tax
purposes.  In rendering this opinion, Dorsey & Whitney LLP will rely upon
certifications by officers of the Original Issuer, SLFC and the Corporation
and certain covenants of the Original Issuer, SLFC and the Corporation
contained in the Indenture with respect to certain matters material to the
exemption of interest on the Tax Exempt Series 1998-1 Notes from federal
income taxation, including, without limitation, certifications and covenants
as to the use of the proceeds of the Tax Exempt Series 1998-1 Notes, and will
assume that the Original Issuer, SLFC and the Corporation will comply with
applicable requirements of the Code.  In the opinion of Dorsey & Whitney LLP,
interest on the Tax Exempt Series 1998-1 Notes is an item of tax preference
which is included in "alternative minimum taxable income" for purposes of the
federal alternative minimum tax under Section 55 of the Code.

     Provisions of the Code impose continuing requirements that must be met
after the issuance of the Tax Exempt Series 1998-1 Notes for interest thereon
to be and remain excludable from gross income for federal income tax
purposes.  Noncompliance with such requirements may cause the interest on the
Tax Exempt Series 1998-1 Notes to be includable in gross income for such
purposes, either prospectively or retroactively to the date of issuance of the
Tax Exempt Series 1998-1 Notes. These requirements include, but are not
limited to, provisions that prescribe that the proceeds of the Tax Exempt
Series 1998-1 Notes and certain other amounts are subject to yield and other
investment limits and provisions that require that certain investment earnings
be rebated on a periodic basis to the Treasury Department of the United
States.

     The Code contains numerous provisions which could affect the federal tax
consequences of owning Tax Exempt Series 1998-1 Notes and receiving interest
thereon.  The following is a brief summary of some of the significant
provisions applicable to particular Tax Exempt Series 1998-1 Noteholders, but
is not intended to be an exhaustive discussion of collateral tax consequences
arising from ownership of the Tax Exempt Series 1998-1 Notes.

                                     -165-
<PAGE>
 
Prospective Tax Exempt Series 1998-1 Noteholders should consult their own tax
advisers with respect to the impact of such provisions on their own tax
situations.

     Interest on the Tax Exempt Series 1998-1 Notes is includable in "net
investment income" of foreign insurance companies for purposes of Section
842(b) of the Code, and may be included in the income of a foreign corporation
for purposes of the branch profits tax imposed by Section 884 of the Code.
Additionally, interest on the Tax Exempt Series 1998-1 Notes constitutes
"passive investment income" for purposes of the tax imposed by Section 1375 of
the Code on such income of certain S corporations.

     Section 265 of the Code denies a deduction for interest on indebtedness
incurred or continued to purchase or carry the Tax Exempt Series 1998-1
Notes.  Indebtedness may be allocated to the Tax Exempt Series 1998-1 Notes
for this purpose even though not directly traceable to the purchase of the Tax
Exempt Series 1998-1 Notes.  The Code also restricts the deductibility of
other expenses allocable to the Tax Exempt Series 1998-1 Notes.  In the case
of a financial institution described in Section 265(b)(5) of the Code, no
deduction is allowed under the Code for that portion of the taxpayer's
interest expense which is allocable to interest on the Tax Exempt Series
1998-1 Notes within the meaning of Section 265(b). In the case of an insurance
company subject to the tax imposed by Section 831 of the Code, the amount
which otherwise would be taken into account as "losses incurred" under Section
832(b)(5) is reduced by an amount equal to 15% of the interest on the Tax
Exempt Series 1998-1 Notes that is received or accrued during the taxable
year.

     Interest on the Tax Exempt Series 1998-1 Notes will be included in
calculating "modified adjusted gross income" under Section 86 of the Code for
purposes of determining whether, and the extent to which, a portion of a
taxpayer's "social security benefits" or "tier 1 railroad retirement benefits"
will be included in gross income for federal income tax.

FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material federal income tax
consequences of the purchase, ownership and disposition of Notes for the
investors described below and is based on the opinions of Dorsey & Whitney
LLP, as tax counsel to the Original Issuer and the Corporation.  The Original
Issuer and the Corporation, as successor to the Original Issuer in respect of
the Notes, are hereinafter referred to collectively as the "Issuer."  This
summary is based upon the Code and other laws, regulations, rulings and
decisions currently in effect, all of which are subject to change.  The
discussion does not deal with all federal tax consequences applicable to all
categories of investors, some of which may be subject to special rules. In
addition, this summary is generally limited to investors who will hold the
Series 1998-1 Notes as "capital assets" (generally, property held for
investment) within the meaning of Section 1221 of the Code.  Investors should
consult their own tax advisors to determine the federal, state, local and
other tax consequences of the purchase, ownership and disposition of the
Series 1998-1 Notes of any series.  Prospective investors should note that no
rulings have been or will be sought from the Internal Revenue Service (the
"Service") with respect to any of the federal income tax consequences
discussed below, and since there are no cases or rulings concerning similar
transactions, there can be no assurance that the Service will not take
contrary positions.

     Characterization of the Trust Estate

     In the opinion of Dorsey & Whitney LLP, based upon certain assumptions
and certain representations of the Issuer, the Series 1998-1 Notes will be
treated as debt of the Issuer, rather than as an interest in the Financed
Eligible Loans and other assets of the Trust Estate, for federal income tax
purposes.  Such opinion will not be binding on the courts or the Service.  It
is possible that the Service could assert that, for purposes of the Code, the
transaction contemplated by this Prospectus constitutes a sale of the assets
comprising the Trust Estate (or an interest therein) to the Holders or that
the relationship which will result from this transaction is that of a
partnership, or an association taxable as a corporation.

                                     -166-
<PAGE>
 
     If, instead of treating the transaction as creating secured debt in the
form of the Series 1998-1 Notes issued by the Issuer as a corporate entity,
the transaction were treated as creating a partnership among the Noteholders,
the Servicer and the Issuer, which has purchased the underlying Trust Estate
assets, the resulting partnership would not be subject to federal income tax.
Rather, the Servicer, the Issuer and each Noteholder would be taxed
individually on their respective distributive shares of the partnership's
income, gain, loss, deductions and credits.  The amount and timing of items of
income and deduction of the Noteholder may differ if the Series 1998-1 Notes
were held to constitute partnership interests, rather than indebtedness.

     If, alternatively, it were determined that this transaction created an
entity other than the Issuer which was classified as a corporation or a
publicly traded partnership taxable as a corporation and was treated as having
sold the assets comprising the Trust Estate, the Trust Estate would be subject
to federal income tax at corporate income tax rates on the income it derives
from the Financed Eligible Loans and other assets, which would reduce the
amounts available for payment to the Noteholders.  Cash payments to the
Noteholders generally would be treated as dividends for tax purposes to the
extent of such corporation's earnings and profits.  A similar result would
apply if the Noteholders were deemed to have acquired stock or other equity
interests in the Issuer.  However, as noted above, the Issuer has been advised
that the Series 1998-1 Notes will be treated as debt of the Issuer for federal
income tax purposes.

     Characterization of the Series 1998-1 Notes as Indebtedness

     The Issuer and the Noteholders express in the Indenture their intent
that, for applicable tax purposes, the Series 1998-1 Notes will be
indebtedness of the Issuer secured by the Trust Estate.  The Issuer and the
Noteholders, by accepting the Series 1998-1 Notes, have agreed to treat the
Series 1998-1 Notes as indebtedness of the Issuer for federal income tax
purposes.  The Issuer intends to treat this transaction as a financing
reflecting the Series 1998-1 Notes as its indebtedness for tax and financial
accounting purposes.

     In general, the characterization of a transaction as a sale of property
or a secured loan, for federal income tax purposes, is a question of fact, the
resolution of which is based upon the economic substance of the transaction,
rather than its form or the manner in which it is characterized.  While the
Service and the courts have set forth several factors to be taken into account
in determining whether the substance of a transaction is a sale of property or
a secured indebtedness, the primary factor in making this determination is
whether the transferee has assumed the risk of loss or other economic burdens
relating to the property and has obtained the benefits of ownership thereof.
Notwithstanding the foregoing, in some instances, courts have held that a
taxpayer is bound by the particular form it has chosen for a transaction, even
if the substance of the transaction does not accord with its form.

     The Issuer believes that it has retained the preponderance of the primary
benefits and burdens associated with Financed Eligible Loans and other assets
comprising the Trust Estate and should, thus, be treated as the owner of such
assets for federal income tax purposes.  If, however, the Service were to
successfully assert that this transaction should be treated as a sale of the
Trust Estate assets, the Service could further assert that the entity created
pursuant to the Indenture, as the owner of the Trust Estate for federal income
tax purposes, should be deemed engaged in a business and, therefore,
characterized as an association taxable as a corporation.

     Taxation of Interest Income of Noteholders

     In the opinion of Dorsey & Whitney LLP, payments of interest with regard
to the Taxable Series 1998-1 Notes will be includable as ordinary income when
received or accrued by the Holders thereof in accordance with their respective
methods of tax accounting and applicable provisions of the Code.  It is
anticipated that the Taxable Series 1998-1 Notes will not be issued with
"original issue discount".  There can be no assurance, however, that the
Service would not assert that the interest payable with respect to the Series
1998-1 Subordinate Notes may not be qualified stated interest because such
payments are not unconditional and that the Series 1998-1 Subordinate Notes
are issued with original issue discount.

                                     -167-
<PAGE>
 
     Payments of interest received with respect to the Taxable Series 1998-1
Notes may also constitute "investment income" for purposes of certain
limitations of the Code concerning the deductibility of investment interest
expense.  Potential Holders should consult their own tax advisors concerning
the treatment of interest payments with regard to the Taxable Series 1998-1
Notes.

     A purchaser who buys a Series 1998-1 Note at a discount from its
principal amount or its adjusted issue price if issued with original issue
discount greater than a specified de minimis amount will be subject to the
market discount rules of the Code.  In general, the market discount rules of
the Code treat principal payments and gain on disposition of a debt instrument
as ordinary income to the extent of accrued market discount.  Although the
accrued market discount on debt instruments such as the Series 1998-1 Notes
which are subject to prepayment based on the prepayment of other debt
instruments is to be determined under regulations yet to be issued, the
legislative history of these provisions of the Code indicate that the same
prepayment assumption used to calculate original issue discount should be
utilized.  Each potential investor should consult his tax advisor concerning
the application of the market discount rules to the Series 1998-1 Notes.

     The annual statement regularly furnished to Holders for federal income
tax purposes will include information regarding payments of interest with
respect to the Series 1998-1 Notes.  As noted above, the Issuer believes,
based on the advice of counsel, that it will retain ownership of the Trust
Estate assets for federal income tax purposes. In the event the Indenture is
deemed to create a pass-through entity as the owner of the Trust Estate assets
for federal income tax purposes instead of the Issuer (assuming such entity is
not, as a result, taxed as an association), the owners of the Series 1998-1
Notes could be required to accrue payments of interest more rapidly than
otherwise would be required.

     Backup Withholding

     Certain purchasers may be subject to backup withholding at the rate of
31% with respect to interest paid with respect to the Taxable Series 1998-1
Notes if the purchasers, upon issuance, fail to supply the Trustee or their
brokers with their taxpayer identification numbers, furnish incorrect taxpayer
identification numbers, fail to report interest, dividends or other
"reportable payments" (as deemed in the Code) properly, or, under certain
circumstances, fail to provide the Trustee with a certified statement, under
penalty of perjury, that they are not subject to backup withholding.
Information returns will be sent annually to the Service and to each purchaser
setting forth the amount of interest paid with respect to the Taxable Series
1998-1 Notes and the amount of tax withheld thereon.

     The Issuer makes no representations regarding the tax consequences of
purchase, ownership or disposition of the Series 1998-1 Notes under the tax
laws of any state, locality or foreign jurisdiction.  Investors considering an
investment in the Series 1998-1 Notes should consult their own tax advisors
regarding such tax consequences.

CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS

     A Beneficial Owner of Series 1998-1 Notes holding securities through
Cedel or Euroclear (or through DTC if the holder has an address outside the
United States) will be subject to the 30% U.S. withholding tax (or, in certain
cases, the 31% backup withholding tax) that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons (as defined below), unless (i) each clearing system, bank or other
financial institution that holds customers' securities in the ordinary course
of its trade or business in the chain of intermediaries between such
Beneficial Owner and the United States entity required to withhold tax
complies with applicable certification requirements and (ii) such Beneficial
Owner takes one of the following steps to obtain an exemption or reduced tax
rate:

     Exemption for non-U.S. Persons (Form W-8).  Beneficial Owners of Series
1998-1 Notes that are non-U.S. Persons can obtain a complete exemption from
the United States withholding tax

                                     -168-
<PAGE>
 
and the backup withholding tax by filing a signed Form W-8 (Certificate of
Foreign Status).  If the information shown in Form W-8 changes, a new form W-8
must be filed within 30 days of such change.

     Exemption for non-U.S. Persons with effectively connected income (Form
4224).  A non-U.S. Person, including a non-United States corporation or bank
with a United States branch, for which the interest income in effectively
connected with its conduct of a trade or business in the United States, can
obtain an exemption from the United States withholding tax and the backup
withholding tax by filing Form 4224 (Exemption from Withholding of Tax on
Income Effectively Connected with the Conduct of a Trade or Business in the
United States).

     Exemption or reduced rate for non-U.S. Persons resident in treaty
countries (Form 1001).  Non-U.S. Persons that are Beneficial Owners of Series
1998-1 Notes residing in a country that has a tax treaty with the United
States can obtain an exemption or reduced tax rate (depending on the treaty
terms) with respect to United States withholding tax and an exemption from the
backup withholding tax by filing Form 1001 (Ownership, Exemption or Reduced
Rate Note).  If the treaty provides only for a reduced rate, the United States
withholding tax will be imposed at that rate unless the filer alternatively
files Form W-8.  Form 1001 may be filed by the Beneficial Owner of the Series
1998-1 Note or his agent.

     Exemption for U.S. Persons (Form W-9).  U.S. Persons generally are not
subject to the United States withholding and can obtain a complete exemption
from the backup withholding tax by filing Form W-9 (Payer's Request for
Taxpayer Identification Number and Certification).

     U.S. Federal Income Tax Reporting Procedure.  The Beneficial Owner of a
Series 1998-1 Note (or in the case of a Form 1001 or a Form 4224 filer, its
agent) files by submitting the appropriate form to the person through whom it
holds (the clearing agency, in the case of persons holding directly on the
books of the clearing agency).  Form W-8 and Form 1001 are effective for three
calendar years and Form 4224 is effective for one calendar year.

     The term "U.S. Person" means (i) a citizen or resident of the United
States, (ii) a corporation or partnership organized in or under the laws of
the United States or any political subdivision thereof, (iii) an estate the
income of which is includable in gross income for United States tax purposes,
regardless of its source, or (iv) a trust if a court within the United States
is able to exercise primary jurisdiction over the administration of the trust
and one or more United States fiduciaries have the authority to control all
substantial decisions of the trust.

     New Withholding Rules in 1999.  Effective January 1, 1999, any foreign
investor that seeks the protection of an income tax treaty with respect to the
imposition of United States withholding tax will generally be required to
obtain a taxpayer identification number ("TIN") from the Service in advance
and provide verification that such investor is entitled to the protection of
the relevant income tax treaty.  Foreign tax-exempt investors will generally
be required to provide verification of their tax-exempt status.  Foreign
investors are urged to consult with their tax advisors with respect to these
new withholding rules.

     This summary does not deal with all aspects of United States federal
income tax withholding that may be relevant to foreign holders of the globally
offered Series 1998-1 Notes. Investors are advised to consult their own tax
advisers for specific tax advice concerning their holding and disposing of the
globally offered Series 1998-1 Notes.


                          ERISA CONSIDERATIONS

     The Employee Retirement Income Security Act of 1974, as amended
("ERISA"), imposes certain fiduciary and prohibited transaction restrictions
on employee pension and welfare benefit plans subject to ERISA ("ERISA
Plans").  Section 4975 of the Code imposes essentially the same prohibited
transaction restrictions on tax-qualified retirement plans described in
Section 401(a) of the Code ("Qualified Retirement Plans") and on Individual
Retirement Accounts ("IRAs") described in Section 408(b) of the Code
(collectively, "Tax-Favored Plans").  Certain

                                     -169-
<PAGE>
 
employee benefit plans, such as governmental plans (as defined in Section
3(32) of ERISA), and, if no election has been made under Section 410(d) of the
Code, church plans (as defined in Section 3(33) of ERISA), are not subject to
ERISA requirements. Accordingly, assets of such plans may be invested in
Series 1998-1 Notes without regard to the ERISA considerations described
below, subject to the provisions of applicable federal and state law.  Any
such plan which is a Qualified Retirement Plan and exempt from taxation under
Sections 401(a) and 501(a) of the Code, however, is subject to the prohibited
transaction rules set forth in the Code.

     In addition to the imposition of general fiduciary requirements,
including those of investment prudence and diversification and the requirement
that a plan's investment be made in accordance with the documents governing
the plan, Section 406 of ERISA and Section 4975 of the Code prohibit a broad
range of transactions involving assets of ERISA Plans and Tax-Favored Plans
and entities whose underlying assets include plan assets by reason of ERISA
Plans or Tax-Favored Plans investing in such entities (collectively, "Benefit
Plans") and persons who have certain specified relationships to the Benefit
Plans ("Parties in Interest" or "Disqualified Persons"), unless a statutory or
administrative exemption is available.  Certain Parties in Interest (or
Disqualified Persons) that participate in a prohibited transaction may be
subject to a penalty (or an excise tax) imposed pursuant to Section 502(i) of
ERISA (or Section 4975 of the Code) unless a statutory or administrative
exemption is available.

     Certain transactions involving the purchase, holding or transfer of the
Series 1998-1 Notes might be deemed to constitute prohibited transactions
under ERISA and the Code if assets of the Original Issuer or the Corporation
were deemed to be assets of a Benefit Plan.  Under a regulation issued by the
United States Department of Labor (the "Plan Assets Regulation"), the assets
of the Original Issuer or the Corporation would be treated as plan assets of a
Benefit Plan for the purposes of ERISA and the Code only if the Benefit Plan
acquires an "equity interest" in the Original Issuer or the Corporation and
none of the exceptions contained in the Plan Assets Regulation is applicable.
An equity interest is defined under the Plan Assets Regulation as an interest
in an entity other than an instrument which is treated as indebtedness under
applicable local law and which has no substantial equity features.  Although
there can be no assurances in this regard, it appears that the Series 1998-1
Notes should be treated as debt without substantial equity features for
purposes of the Plan Assets Regulation.  However, without regard to whether
the Series 1998-1 Notes are treated as an equity interest for such purposes,
the acquisition or holding of Series 1998-1 Notes by or on behalf of a Benefit
Plan could be considered to give rise to a prohibited transaction if the
Original Issuer, the Corporation or the Trustee, or any of their respective
affiliates, is or becomes a party in interest or a disqualified person with
respect to such Benefit Plan.  In such case, certain exemptions from the
prohibited transaction rules could be applicable depending on the type and
circumstances of the plan fiduciary making the decision to acquire a Note.
Included among these exemptions are:  Prohibited Transaction Class Exemption
("PTCE") 96-23, regarding transactions effected by "in-house asset managers";
PTCE 90-1, regarding investments by insurance company pooled separate
accounts; PTCE 95-60, regarding transactions effected by "insurance company
general account"; PTCE 91-38, regarding investments by bank collective
investment funds; and PTCE 84-14, regarding transactions effected by
"qualified professional assets managers."

     Any ERISA Plan fiduciary considering whether to purchase Series 1998-1
Notes on behalf of an ERISA Plan should consult with its counsel regarding the
applicability of the fiduciary responsibility and prohibited transaction
provisions of ERISA and the Code to such investment and the availability of
any of the exemptions referred to above.  Persons responsible for investing
the assets of Tax-Favored Plans that are not ERISA Plans should seek similar
counsel with respect to the prohibited transaction provisions of the Code.


           CERTAIN RELATIONSHIPS AMONG FINANCING PARTICIPANTS

     As described under "The Original Issuer", "The Servicer" and "The
Corporation", the Corporation will be a wholly-owned subsidiary of SLFC, which
in turn will initially be a wholly-owned subsidiary of the Original Issuer.
There is no assurance that the Original Issuer will continue to own all or any
of the stock of SLFC.  The Original Issuer will have no obligations with
respect to the Notes or the Indenture after the transfers described under "The
Original Issuer" and "The Corporation."  Except for its obligations under the
SLFC Servicing Agreement,

                                     -170-
<PAGE>
 
SLFC will have no obligations with respect to the Notes or the Indenture.  The
Corporation will have no full-time employees, but will initially contract with
SLFC to perform the Corporation's obligations under the Indenture.

     The boards of directors of the Original Issuer, the Corporation and SLFC
presently consist of the same four persons, and two of those persons also are
members of the boards of directors of EAC and EASCI.

     The Trustee is also the trustee for the Original Issuer's outstanding
student loan revenue bond and student loan asset-backed note issues, which
will be refunded by the Series 1998-1 Notes.  The Trustee and its affiliates
have in the past entered into student loan purchase agreements with the
Original Issuer, including Student Loan Purchase Agreements pursuant to which
the Original Issuer acquired as of December 31, 1997, approximately $144
million outstanding principal amount of Eligible Loans which will be Financed
under the Indenture.  The Corporation expects that the Trustee will enter into
Student Loan Purchase Agreements providing for the sale of a substantial
amount of additional Eligible Loans.  The Original Issuer also has obtained
(and the Corporation may in the future obtain) financial services from the
Trustee and related entities.

     Foley & Lardner, counsel to the Underwriters, has from time to time
represented, and is currently representing, the Original Issuer in
connection with various matters (including matters relating to its
transfer of assets to SLFC).  In addition, Foley & Lardner has from time
to time represented, and is currently representing, EAC in connection
with various matters.

     For a discussion of certain relationships between Underwriters or
affiliates of Underwriters and the Original Issuer or the Corporation,
see "Plan of Distribution".


                          PLAN OF DISTRIBUTION

     Subject to the terms and conditions set forth in the Underwriting
Agreement for the sale of the Series 1998-1 Notes, dated February 12, 1998
(the "Underwriting Agreement"), the Original Issuer has agreed to sell and the
Underwriters have jointly and severally (subject to the limitations discussed
below) agreed to purchase all (but not less than all) of the Series 1998-1
Notes.  The obligation of U.S. Bancorp Investments, Inc. to purchase the
Series 1998-1 Notes is limited to such principal amount of the Series 1998-1
Notes as does not exceed 10% of the capital stock actually paid in and
unimpaired and 10% of the unimpaired surplus funds of U.S. Bank National
Association (also doing business as First Bank National Association), which is
the commercial bank which owns U.S. Bancorp Investments, Inc. as described
below.

     The Original Issuer has been advised by the Underwriters that the
Underwriters propose initially to offer the Series 1998-1 Notes to the public
at the public offering price with respect to each series set forth on the
cover page of this Prospectus.  After the initial public offering, the public
offering price may be changed.

     The Original Issuer and SLFC have agreed to indemnify the Underwriters
against certain liabilities including liabilities under the Securities Act of
1933, as amended, and the Original Issuer has agreed to reimburse the
Underwriters for the fees and expenses of counsel to the Underwriters.

     The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with the
Regulation M under the Exchange Act.  Over-allotment involves syndicate sales
in excess of the offering size, which creates a syndicate short position.
Stabilizing transactions permit bids to purchase the underlying security so
long as the stabilizing bids do not exceed a specific maximum.  Syndicate
covering transactions involve purchases of the Series 1998-1 Notes in the open
market after the distribution has been completed in order to cover syndicate
short positions.  Penalty bids permit the Underwriters to reclaim a selling

                                     -171-
<PAGE>
 
concession from a syndicate member when the Series 1998-1 Notes originally
sold by such syndicate member are purchased in a syndicate covering
transaction to cover syndicate short positions.  Such stabilizing
transactions, syndicate covering transactions and penalty bids may cause the
price of the Series 1998-1 Notes to be higher than it would otherwise be in
the absence of such transactions.

     Each Underwriter has represented and agreed that it has not offered or
sold, and will not offer or sell Series 1998-1 Notes to persons in the United
Kingdom except to persons whose ordinary activities involve them in acquiring,
holding, managing or disposing of investments (as principal or agent) for the
purposes of their businesses or otherwise in circumstances which have not
resulted, and will not result in an offer to the public in the United Kingdom
within the meaning of the U.K. Regulations.

     U.S. Bancorp Investments, Inc. is a wholly-owned subsidiary of U.S. Bank
National Association (also doing business as First Bank National Association),
which is the Trustee.  Norwest Investment Services, Inc. is an affiliate of
Norwest Bank of South Dakota, N.A., which will act as a deposit agent for the
receipt of certain funds credited to the Revenue Fund.  Salomon Smith Barney
and U.S. Bancorp Investments, Inc. have provided to the Original Issuer from
time to time, and may provide to the Corporation in the future, investment or
commercial banking services, for which such Underwriters have received or will
receive customary fees and commissions.  First Bank National Association and
banks that are affiliates of Norwest Investment Services, Inc. have in the
past entered into student loan purchase agreements with the Original Issuer.
The Corporation expects that such banks will enter into Student Loan Purchase
Agreements providing for the sale of a substantial amount of additional
Eligible Loans.


                             LEGAL MATTERS

     Certain legal matters will be passed upon for the Original Issuer and the
Corporation by Dorsey & Whitney LLP, Minneapolis, Minnesota, Bond Counsel and
special counsel for the Original Issuer and the Corporation.  Certain legal
matters will be passed upon for the Underwriters by Foley & Lardner,
Milwaukee, Wisconsin.


                                EXPERTS

     The balance sheet of the Corporation as of January 27, 1998, has been
included herein and in the registration statement in reliance upon the report
of Eide Helmeke PLLP, Aberdeen, South Dakota, independent certified public
accountants, appearing elsewhere herein, and upon the authority of said firm
as experts in accounting and auditing.


                                RATINGS

     It is a condition to the issuance of the Series 1998-1 Notes that the
Series 1998-1 Senior Notes each be rated "AAA" by Fitch IBCA, Inc. and "Aaa"
by Moody's Investors Services, Inc., and that the Series 1998-1 Subordinate
Notes be rated no less than "A" by Fitch IBCA, Inc. and "A3" by Moody's
Investors Services, Inc..  The Original Issuer has applied for ratings of the
Series 1998-1 Notes from Moody's Investors Services, Inc.and Fitch IBCA, Inc.
No application was made to any other rating agency for the purpose of
obtaining additional ratings of the Series 1998-1 Notes.

     Any ratings, if assigned, reflect only the view of the Rating Agency.
Any explanation of the significance of the ratings may be obtained only from
the Rating Agency.  The Original Issuer and the Corporation furnished to the
Rating Agencies certain information and materials, some of which may not have
been included in this Prospectus, relating to the Series 1998-1 Notes, the
Original Issuer and the Corporation. Generally, rating agencies base their
ratings on such information and materials and on investigation, studies and
assumptions made by the rating agencies.  There can be no assurance that
ratings when assigned will continue for any given period of time

                                     -172-
<PAGE>
 
or that they will not be lowered or withdrawn entirely by a Rating Agency if
in its judgment circumstances so warrant. If ratings are assigned, any such
downward change in or withdrawal of a rating may have an adverse effect on the
marketability or market price of the Series 1998-1 Notes.

     Fitch IBCA, Inc. has stated that its ratings on Series 1998-1 Notes do
not address:  (a) the market liquidity of the Series 1998-1 Notes or (b) any
Carry-Over Amount that may accrue with respect to the Taxable Series 1998-1
Notes.

     The Corporation expects to furnish to each Rating Agency information and
materials that it may request. However, the Corporation assumes no obligation
to furnish requested information and materials, and may issue additional
obligations for which a rating is not requested.  Failure to furnish requested
information and materials, or the issuance of debt for which a rating is not
requested, may result in the suspension or withdrawal of a Rating Agency's
ratings on the Series 1998-1 Notes.

     A securities rating addresses the likelihood of the receipt by Holders of
the Series 1998-1 Notes of payments of principal and interest from assets in
the Trust Estate.  The rating takes into consideration the characteristics of
the Financed Eligible Loans, and the structural, legal and tax aspects
associated with the Series 1998-1 Notes.  A securities rating is not a
recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the assigning rating agency.  Each securities
rating should be evaluated independently of similar ratings on different
securities.


                   GLOSSARY OF CERTAIN DEFINED TERMS

     In addition to the terms defined elsewhere in this Prospectus, the
following terms shall have the following respective meanings.  Any term used
with an initial capital letter but not defined herein shall have the meaning
given such term in the Indenture.

     "`AA' Composite Commercial Paper Rate" shall mean, with respect to a
series of Tax Exempt Series 1998-1 Senior Notes, (i) the interest equivalent
of the 30-day rate on commercial paper placed on behalf of issuers whose
corporate bonds are rated "AA" by S&P, or the equivalent of such rating by
S&P, as such 30-day rate is made available on a discount basis or otherwise by
the Federal Reserve Bank of New York for the Business Day immediately
preceding such date of determination, or (ii) if the Federal Reserve Bank of
New York does not make available any such rate, then the arithmetic average of
the interest equivalent of the 30-day rate on commercial paper placed on
behalf of such issuers, as quoted to the Auction Agent on a discount basis or
otherwise by the Commercial Paper Dealers, as of the close of business on the
Business Day immediately preceding the date of determination.  If, at the time
quotations are required, any Commercial Paper Dealer does not quote a
commercial paper rate required to determine the "`AA' Composite Commercial
Paper Rate," or if less than three Commercial Paper Dealers are then serving
as such for any reason, the "`AA' Composite Commercial Paper Rate" shall be
determined on the basis of such quotation or quotations furnished by the
Commercial Paper Dealer or Commercial Paper Dealers then serving as such and
providing a quotation.  For purposes of this definition, the "interest
equivalent" of a rate stated on a discount basis (a "discount rate") for
commercial paper of a given day's maturity shall be equal to the product of
(a) 100, times (b) the quotient (rounded upward to the next higher .00001) of
(1) the discount rate (expressed in decimals) divided by (2) the difference
between (A) 1.00, and (B) a fraction, the numerator of which shall be the
product of the discount rate (expressed in decimals) times the number of days
from (and including) the date of determination to, but excluding, the date on
which such commercial paper matures, and the denominator of which shall be
360.

     "Account" shall mean any of the accounts created within the Funds
established by the Indenture.

     "Accountant" shall mean Eide Helmeke PLLP, Certified Public Accountants,

     taken in connection with the enforcement of the terms and
     conditions of the Indenture and requiring the Trustee to waive
     Events of Default: (x) the Holders of a majority in aggregate
     Principal Amount of the Senior Notes Outstanding, unless the

     its sole discretion, determine that the requested action is not in
     the overall interest of the Senior Beneficiaries or shall have

Subordinate Obligations are Outstanding, the Holders of a majority in
aggregate Principal Amount of Class C Notes Outstanding.

     "Additional Notes" shall have the meaning assigned thereto on page 4 of
this Prospectus.

     "Administrative Cost and Note Fee Rate" shall mean a rate per annum equal
to the sum of (i) 1.275%, (ii) the Auction Agent fee rate (initially 0.025%,
but subject to change in accordance with the provisions of the Auction Agent
Agreement), and (iii) the Broker-Dealer fee rate (initially 0.25%, but subject
to change in accordance with the provisions of the Auction Agent Agreement).

     "Administrative Expenses" shall mean the Corporation's actual expenses,
