                  (xiv)  It is the intention of ▇▇▇▇▇▇ ▇▇▇, the Interim Eligible
                  Lender Trustee and Funding, and ▇▇▇▇▇▇ Mae hereby warrants
                  that, the transfer and assignment herein contemplated
                  constitute a valid sale of the Loans from ▇▇▇▇▇▇ ▇▇▇ to the

                  ▇▇▇▇▇▇ Mae;
                  (xv)   The Eligible Lender Trustee and the Seller have caused
                  or will have caused, within ten days, the filing of all
                  appropriate financing statements in the proper filing office
                  in the appropriate jurisdictions under applicable law in order
                  to perfect the security interest in the Loans granted to the
                  Eligible Lender Trustee hereunder;
                  (xvi)  There is only one original executed copy of the
                  promissory note evidencing each Loan. The Eligible Lender
                  Trustee has in its possession a copy of the endorsement and
                  Loan Transmittal Summary Form identifying the Notes that
                  constitute or evidence the Loans. The Notes that constitute or
                  evidence the Loans do not have any marks or notations
                  indicating that they have been pledged, assigned or otherwise
                  conveyed to any Person other than the Eligible Lender Trustee.
                  All financing statements filed or to be filed against the
                  Interim Eligible Lender Trustee and the Seller in favor of the
                  Eligible Lender Trustee in connection herewith describing the
                  Loans contain a statement to the following effect: "A purchase
                  of or security interest in any collateral described in this
                  financing statement will violate the rights of the Eligible
                  Lender Trustee;"
                  (xvii) Other than the security interest granted to the
                  Eligible Lender Trustee pursuant to this Agreement, the Seller
                  and the Interim Eligible Lender Trustee have not pledged,
                  assigned, sold, granted a security interest in, or otherwise

                  aware of any financing statements against the Seller or the
                  Interim Eligible Lender Trustee that include a description
                  of collateral covering the Loans other than any financing
                  statement relating to the security interest granted to the
                  Eligible Lender Trustee hereunder or that has been terminated.
                  The Seller and the Interim Eligible Lender Trustee are not
                  aware of any judgment or tax lien filings against the Seller
                  or the Interim Eligible Lender Trustee; and
                  (xviii) No Borrower of any Loan as of the Cutoff Date is noted
                  in the related Loan File as being currently involved in a
                  bankruptcy proceeding.
         (C)      The Interim Eligible Lender Trustee represents and warrants
         that as of the date of each Purchase Agreement and each ▇▇▇▇ of Sale:
                  (i)    The Interim Eligible Lender Trustee is duly organized
         and validly existing in good standing under the laws of its governing
         jurisdiction and has an office located within the State of Delaware. It
         has all requisite corporate power and authority to execute, deliver and
         perform its obligations under this Purchase Agreement;
                  (ii)   The Interim Eligible Lender Trustee has taken all
         corporate action necessary to authorize the execution and delivery by
         it of the Purchase Agreement, and the Purchase Agreement will be
         executed and delivered by one of its officers who is duly authorized to
         execute and deliver the Purchase Agreement on its behalf;
                  (iii)  Neither the execution nor the delivery by it of the
         Purchase Agreement, nor the consummation by it of the transactions
         contemplated hereby nor compliance by it with any of the terms or
         provisions hereof will contravene any Federal or Delaware state law,
         governmental rule or regulation governing the banking or trust powers
         of the Interim Eligible Lender Trustee or any judgment or order binding
         on it, or constitute any default under its charter documents or by-laws
         or any indenture, mortgage, contract, agreement or instrument to which
         it is a party or by which any of its properties may be bound; and
                  (iv)   The Interim Eligible Lender Trustee is an "eligible
         lender" as such term is defined in Section 435(d) of the Higher
         Education Act, for purposes of holding legal title to the Trust Student
         Loans as contemplated by the Purchase Agreement and the other Basic
         Documents, it has a lender identification number with respect to the
         Trust Student Loans from the Department and has in effect a Guarantee
         Agreement with each of the Guarantors with respect to the Trust Student
         Loans.
SECTION 6. PURCHASE OF TRUST STUDENT LOANS; REIMBURSEMENT
         Each party to this Agreement shall give notice to the other parties
promptly, in writing, upon the discovery of any breach of ▇▇▇▇▇▇ Mae's
representations and warranties made pursuant to
Section 5 hereof which has a materially adverse effect on the interest of
Funding in any Trust Student Loan. In the event of such a material breach which
is not curable by reinstatement of Guarantor's guarantee of such Trust Student
Loan, ▇▇▇▇▇▇ Mae shall repurchase any affected Trust Student Loan not later than
120 days following the earlier of the date of discovery of such material breach
and the date of receipt of the Guarantor reject transmittal form with respect to
such Trust Student Loan. In the event of such a material breach which is curable
by reinstatement of the Guarantor's guarantee of such Trust Student Loan, unless
the material breach shall have been cured within 360 days following the earlier
of the date of discovery of such material breach and the date of receipt of the
Guarantor reject transmittal form with respect to such Trust Student Loan,
▇▇▇▇▇▇ ▇▇▇ shall purchase such Trust Student Loan not later than the sixtieth
day following the end of such 360-day period. ▇▇▇▇▇▇ Mae shall also remit as
provided in Section 2.6 of the Administration Agreement on the date of purchase
of any Trust Student Loan pursuant to this Section 6 an amount equal to all
non-guaranteed interest amounts and forfeited Interest Subsidy Payments and
Special Allowance Payments with respect to such Trust Student Loan. In
consideration of the purchase of any such Trust Student Loan pursuant to this
Section 6, ▇▇▇▇▇▇ ▇▇▇ shall remit the Purchase Amount in the manner specified in
Section 2.6 of the Administration Agreement.
         In addition, if any breach of Section 5 hereof by ▇▇▇▇▇▇ Mae does not
trigger such purchase obligation but does result in the refusal by a Guarantor
to guarantee all or a portion of the accrued interest (or any obligation of
Funding to repay such interest to a Guarantor), or the loss (including any
obligation of Funding to repay the Department) of Interest Subsidy Payments and
Special Allowance Payments, with respect to any Trust Student Loan affected by
such breach, then ▇▇▇▇▇▇ ▇▇▇ shall reimburse Funding by remitting an amount
equal to the sum of all such non-guaranteed interest amounts and such forfeited
Interest Subsidy Payments or Special Allowance Payments in the manner specified
in Section 2.6 of the Administration Agreement not later than (i) the last day
of the next Collection Period ending not less than 60 days from the date of the
Guarantor's refusal to guarantee all or a portion of accrued interest or loss of
Interest Subsidy Payments or Special Allowance Payments, or (ii) in the case
where ▇▇▇▇▇▇ ▇▇▇ reasonably believes such losses are likely to be collected, not
later than the last day of the next Collection Period ending not less than 360
days from the date of the Guarantor's refusal to guarantee all or a portion of
accrued interest or loss of Interest Subsidy Payments or Special Allowance
Payments. At the time such payment is made, ▇▇▇▇▇▇ Mae shall not be required to
reimburse Funding for interest that is then capitalized, however, such amounts
shall be reimbursed if the borrower subsequently defaults and such capitalized
interest is not paid by the Guarantor.
         Anything in this Section 6 to the contrary notwithstanding, if as of
the last Business Day of any month the aggregate outstanding principal amount of
Trust Student Loans with respect to which claims have been filed with and
rejected by a Guarantor or with respect to which the Servicer determines that
claims cannot be filed pursuant to the Higher Education Act as a result
of a breach by ▇▇▇▇▇▇ ▇▇▇ or the Servicer, exceeds 1% of the Pool Balance,
▇▇▇▇▇▇ Mae (and the Servicer as provided in the Servicing Agreement) shall
purchase, within 30 days of a written request of the Eligible Lender Trustee or
the Indenture Trustee, such affected Trust Student Loans in an aggregate
principal amount such that after such purchase the aggregate principal amount of
such affected Trust student Loans is less than 1% of the Pool Balance. The Trust
Student Loans to be purchased by ▇▇▇▇▇▇ ▇▇▇ and the Servicer pursuant to the
preceding sentence shall be based on the date of claim rejection (or the date of
notice referred to in the first sentence of this Section 6) with Trust Student
Loans with the earliest such date to be purchased first.
         In lieu of repurchasing Trust Student Loans pursuant to this Section 6,
▇▇▇▇▇▇ Mae may, at its option, substitute Eligible Loans or arrange for the
substitution of Eligible Loans which are substantially similar on an aggregate
basis as of the date of substitution to the Trust Student Loans for which they
are being substituted with respect to the following characteristics:
                  (1)    status (i.e., in-school, grace, deferment, forbearance
                         or repayment),
                  (2)    program type (i.e., Unsubsidized ▇▇▇▇▇▇▇▇, Subsidized
                         ▇▇▇▇▇▇▇▇, Consolidation (pre-1993 vs. post-1993), PLUS
                         or SLS),
                  (3)    school type,
                  (4)    total return,
                  (5)    principal balance, and
                  (6)    remaining term to maturity.
         In addition, each substituted Eligible Loan will comply, as of the date
of substitution, with all of the representations and warranties made hereunder.
In choosing Eligible Loans to be substituted pursuant to this Section 6, ▇▇▇▇▇▇
▇▇▇ shall make a reasonable determination that the Eligible Loans to be
substituted will not have a material adverse effect on the Noteholders.
         In the event that ▇▇▇▇▇▇ Mae elects to substitute Eligible Loans
pursuant to this Section 6, ▇▇▇▇▇▇ ▇▇▇ will remit to the Administrator the
amount of any shortfall between the Purchase Amount of the substituted Eligible
Loans and the Purchase Amount of the Trust Student Loans for which they are
being substituted. ▇▇▇▇▇▇ Mae shall also remit to the Administrator an amount
equal to all non-guaranteed interest amounts and forfeited Interest Subsidy
Payments and Special Allowance Payments with respect to the Trust Student Loans
in the manner provided in Section 2.6 of the Administration Agreement. The sole
remedy of Funding, the Eligible Lender Trustee and the Noteholders with respect
to a breach by ▇▇▇▇▇▇ ▇▇▇ pursuant to Section 5 hereof shall be to require
▇▇▇▇▇▇ Mae to purchase Trust Student Loans, to reimburse Funding as provided
above
or to substitute Student Loans pursuant to this Section. The Eligible Lender
Trustee shall have no duty to conduct any affirmative investigation as to the
occurrence of any condition requiring the purchase of any Trust Student Loan or
the reimbursement for any interest penalty pursuant to this Section 6.
SECTION 7.  OBLIGATION TO REMIT SUBSEQUENT PAYMENTS AND FORWARD COMMUNICATIONS
         (A) Any payment received by ▇▇▇▇▇▇ ▇▇▇ with respect to amounts accrued
         after the Date of the ▇▇▇▇ of Sale for any Loan sold to Funding, which
         payment is not reflected in the Loan Transmittal Summary Form, shall be
         received by ▇▇▇▇▇▇ ▇▇▇ in trust for the account of Funding and ▇▇▇▇▇▇
         Mae hereby disclaims any title to or interest in any such amounts.
         Within two (2) business days following the date of receipt, ▇▇▇▇▇▇ ▇▇▇
         shall remit to Funding an amount equal to any such payments on a list
         provided by Funding identifying the Loans with respect to which such
         payments were made, the amount of each such payment and the date each
         such payment was received.
         (B) Any written communication received at any time by ▇▇▇▇▇▇ Mae with
         respect to any Loan subject to this Purchase Agreement shall be
         transmitted by ▇▇▇▇▇▇ ▇▇▇ to Servicer within two (2) business days of
         receipt. Such communications shall include, but not be limited to,
         letters, notices of death or disability, notices of bankruptcy, forms
         requesting deferment of repayment or loan cancellation, and like
         documents.
SECTION 8.  CONTINUING OBLIGATION OF ▇▇▇▇▇▇ ▇▇▇
         ▇▇▇▇▇▇ Mae shall provide all reasonable assistance necessary for
Funding to resolve account problems raised by any Borrower, the Guarantor or the
Secretary provided such account problems are attributable to or are alleged to
be attributable to (a) an event occurring during the period ▇▇▇▇▇▇ ▇▇▇ owned the
Loan, or (b) a payment made or alleged to have been made to ▇▇▇▇▇▇ Mae. Further,
▇▇▇▇▇▇ ▇▇▇ agrees to execute any financing statements at the request of Funding
in order to reflect Funding's interest in the Loans.
SECTION 9.  LIABILITY OF ▇▇▇▇▇▇ MAE; INDEMNITIES
         ▇▇▇▇▇▇ ▇▇▇ shall be liable in accordance herewith only to the extent of
the obligations specifically undertaken by ▇▇▇▇▇▇ Mae under this Purchase

         the Interim Eligible Lender Trustee in its individual capacity and
         their officers, directors, employees and agents from and against any

     Lender Trustee on behalf of Funding, or asserted with respect to ownership
     of the Trust Student Loans) and costs and expenses in defending against the
     same.
     (ii)  ▇▇▇▇▇▇ ▇▇▇ shall indemnify, defend and hold harmless Funding and the
     Interim Eligible Lender Trustee in its individual capacity, and the
     officers, directors, employees and agents of Funding, and the Interim
     Eligible Lender Trustee from and against any and all costs, expenses,
     losses, claims, damages and liabilities arising out of, or imposed upon
     such Person through, ▇▇▇▇▇▇ Mae's willful misfeasance, bad faith or gross
     negligence in the performance of its duties under the Purchase Agreement,
     or by reason of reckless disregard of its obligations and duties under the
     Purchase Agreement.
     (iii) ▇▇▇▇▇▇ ▇▇▇ shall be liable as primary obligor for, and shall

     the Purchase Agreement, the other Basic Documents, the acceptance or
     performance of the trusts and duties set forth herein and in the Sale
     Agreement or the action or the inaction of the Interim Eligible Lender
     Trustee hereunder, except to the extent that such cost, expense, loss,
     claim, damage, obligation or liability: (a) shall be due to the willful
     misfeasance, bad faith or negligence (except for errors in judgment) of the
     Interim Eligible Lender Trustee, (b) shall arise from any breach by the
     Interim Eligible Lender Trustee of its covenants made under any of the
     Basic Documents; or (c) shall arise from the breach by the Interim Eligible
     Lender Trustee of any of its representations or warranties made in its
     individual capacity set forth in these Master Terms or any Purchase

     indemnity will be sought pursuant to this paragraph, the Interim Eligible

     Indemnification under this Section shall survive the resignation or removal
of the Interim Eligible Lender Trustee and the termination of these Master
Terms, and shall include reasonable fees and expenses of counsel and expenses of
litigation. If ▇▇▇▇▇▇ ▇▇▇ shall have made any indemnity payments pursuant to
this Section and the Person to or on behalf of whom such payments are made

SECTION 10. MERGER OR CONSOLIDATION OF, OR ASSUMPTION OF THE OBLIGATIONS OF
            ▇▇▇▇▇▇ ▇▇▇
     Any Person (a) into which ▇▇▇▇▇▇ Mae may be merged or consolidated, (b)
which may result from any merger or consolidation to which ▇▇▇▇▇▇ ▇▇▇ shall be a
party or (c) which may succeed to the properties and assets of ▇▇▇▇▇▇ Mae
substantially as a whole, shall be the successor to ▇▇▇▇▇▇ ▇▇▇ without the
execution or filing of any document or any further act by any of the parties to
this Purchase Agreement; provided, however, that ▇▇▇▇▇▇ Mae hereby covenants
that it will not consummate any of the foregoing transactions except upon
satisfaction of the following: (i) the surviving Person, if other than ▇▇▇▇▇▇
▇▇▇, executes an agreement of assumption to perform every obligation of ▇▇▇▇▇▇
Mae under the Purchase Agreement, (ii) immediately after giving effect to such

been breached, (iii) the surviving Person, if other than ▇▇▇▇▇▇ ▇▇▇, shall have
delivered to the Interim Eligible Lender Trustee an Officers' Certificate and an
Opinion of Counsel each stating that such consolidation, merger or succession

Condition shall have been satisfied with respect to such transaction (iv) if
▇▇▇▇▇▇ Mae is not the surviving entity, ▇▇▇▇▇▇ ▇▇▇ shall have delivered to the
Interim Eligible Lender Trustee an Opinion of Counsel either (A) stating that,

statements and amendments thereto have been executed and filed that are
necessary fully to preserve and protect the interest of Funding and the Interim
Eligible Lender Trustee in the Loans and reciting the details of such filings,
or (B) stating that, in the opinion of such counsel, no such action shall be
necessary to preserve and protect such interests.
SECTION 11. LIMITATION ON LIABILITY OF ▇▇▇▇▇▇ MAE AND OTHERS
     ▇▇▇▇▇▇ ▇▇▇ and any director or officer or employee or agent thereof may
rely in good faith on the advice of counsel or on any document of any kind,
prima facie properly executed and submitted by any Person respecting any matters
arising hereunder (provided that such reliance shall not limit in any way ▇▇▇▇▇▇
Mae's obligations under Section 6). ▇▇▇▇▇▇ ▇▇▇ shall not be under any obligation
to appear in, prosecute or defend any legal action that shall not be incidental
to its obligations under these Master Terms or any Purchase Agreement, and that
in its opinion may involve it in any expense or liability. Except as provided
herein, the repurchase (or substitution) and reimbursement obligations of ▇▇▇▇▇▇
Mae will constitute the sole remedy available to Funding for uncured breaches;
provided, however, that the information with respect to the Loans listed on the
▇▇▇▇ of Sale may be adjusted in the ordinary course of business subsequent to
the date of the ▇▇▇▇ of Sale and to the extent that the aggregate Principal
Balance of the Loans listed on the ▇▇▇▇ of Sale is less than the aggregate
Principal Balance stated on the ▇▇▇▇
of Sale, ▇▇▇▇▇▇ ▇▇▇ shall remit such amount to the Interim Eligible Lender
Trustee on behalf of Funding. Such reconciliation payment shall be made from
time to time but no less frequently than semi-annually.
SECTION 12. LIMITATION OF LIABILITY OF INTERIM ELIGIBLE LENDER
     Notwithstanding anything contained herein to the contrary, these Master
Terms and any Purchase Agreement have been signed by Chase Manhattan Bank USA,
National Association not in its individual capacity but solely in its capacity
as Interim Eligible Lender Trustee for Funding and in no event shall Chase
Manhattan Bank USA, National Association in its individual capacity have any
liability for the representations, warranties, covenants, agreements or other
obligations of Funding, under these Master Terms or any Purchase Agreement or in
any of the certificates, notices or agreements delivered pursuant hereto, as to
all of which recourse shall be had solely to the assets of Funding.
SECTION 13. EXPENSES
     Except as otherwise provided herein, each party to these Master Terms or
any Purchase Agreement shall pay its own expense incurred in connection with the
preparation, execution and delivery of these Master Terms and any Purchase
Agreement and the transactions contemplated herein or therein.
SECTION 14. SURVIVAL OF COVENANTS/SUPERSESSION
     All covenants, agreements, representations and warranties made herein and
in or pursuant to any Purchase Agreements executed pursuant to these Master
Terms shall survive the consummation of the purchase of the Loans provided for
in each Purchase Agreement. All covenants, agreements, representations and
warranties made or furnished pursuant hereto by or on behalf of ▇▇▇▇▇▇ ▇▇▇ shall
bind and inure to the benefit of any successors or assigns of Funding and shall
survive with respect to each Loan. Each Purchase Agreement supersedes all
previous agreements and understandings between Funding and ▇▇▇▇▇▇ Mae with
respect to the subject matter thereof. These Master Terms and any Purchase
Agreement may be changed, modified or discharged, and any rights or obligations
hereunder may be waived, only by a written instrument signed by a duly
authorized officer of the party against whom enforcement of any such waiver,
change, modification or discharge is sought. The waiver by Funding of any
covenant, agreement, representation or warranty required to be made or furnished
by ▇▇▇▇▇▇ ▇▇▇ or the waiver by Funding of any provision herein contained or
contained in any Purchase Agreement shall not be deemed to be a waiver of any
breach of any other covenant, agreement, representation, warranty or provision
herein contained, nor shall any waiver or any custom or practice which may
evolve between the parties in the administration of the terms hereof or of any
Purchase Agreement, be construed to lessen the right of Funding to insist upon
the performance by ▇▇▇▇▇▇ Mae in strict accordance with said terms.
SECTION 15. COMMUNICATION AND NOTICE REQUIREMENTS
     All communications, notices and approvals provided for hereunder shall be
in writing and mailed or delivered to ▇▇▇▇▇▇ ▇▇▇ or Funding, as the case may be,
addressed as set forth in the Purchase Agreement or at such other address as
either party may hereafter designate by notice to the other party. Notice given
in any such communication, mailed to ▇▇▇▇▇▇ Mae or Funding by appropriately
addressed registered mail, shall be deemed to have been given on the day
following the date of such mailing.
SECTION 16. FORM OF INSTRUMENTS
     All instruments and documents delivered in connection with these Master
Terms and any Purchase Agreement, and all proceedings to be taken in connection
with these Master Terms and any Purchase Agreement and the transactions
contemplated herein and therein, shall be in a form as set forth in the
attachments hereto, and Funding shall have received copies of such documents as
it or its counsel shall reasonably request in connection therewith. Any
instrument or document which is substantially in the same form as an Attachment
hereto or a recital herein will be deemed to be satisfactory as to form.
SECTION 17. AMENDMENT
     These Master Terms and any Purchase Agreement may be amended by the parties
thereto without the consent of the related Noteholders for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of such Master Terms and Purchase Agreements or of modifying in any manner the
rights of such Noteholders; provided that such action will not, in the opinion
of counsel satisfactory to the related Indenture Trustee, materially and
adversely affect the interest of any such Noteholder.
     In addition, these Master Terms and any Purchase Agreement may also be
amended from time to time by ▇▇▇▇▇▇ ▇▇▇, the Interim Eligible Lender Trustee and
Funding, with the consent of the Noteholders of Notes evidencing a majority of
the Outstanding Amount of the Notes, for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of these Master
Terms or any Purchase Agreements or of modifying in any manner the rights of the
Noteholders; provided, however, that no such amendment shall (a) increase or
reduce in any manner the amount of, or accelerate or delay the time of,
collections of payments with respect to Loans or distributions that shall be
required to be made for the benefit of the Noteholders or (b) reduce the
aforesaid percentage of the Outstanding Amount of the Notes, the Noteholders of
which are required to consent to any such amendment, without the consent of all
outstanding Noteholders.
     Promptly after the execution of any such amendment or consent (or, in the
case of the Rating Agencies, five Business Days prior thereto), the Interim
Eligible Lender Trustee shall furnish written notification of the substance of
such amendment or consent to the Indenture Trustee and each of the Rating
Agencies.
     It shall not be necessary for the consent of Noteholders pursuant to this
Section to approve the particular form of any proposed amendment or consent, but
it shall be sufficient if such consent shall approve the substance thereof.
     Prior to the execution of any amendment to these Master Terms, the Interim
Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that execution of such amendment is authorized or permitted by
this Agreement and the Opinion of Counsel referred to in Section 7.1 I(i) of the
Administration Agreement. The Interim Eligible Lender Trustee may, but shall not
be obligated to, enter into any such amendment which affects the Interim
Eligible Lender Trustee's own rights, duties or immunities under this Agreement
or otherwise.
SECTION 18. NONPETITION COVENANTS
     Notwithstanding any prior termination of these Master Terms ▇▇▇▇▇▇ Mae and
