as of January 19, 2000 and is made in respect of the Credit  Agreement  dated as
of July 12, 1996 as amended and in effect  immediately  prior to the date hereof
(the "Credit Agreement") by and among PSC Scanning, Inc., a Delaware corporation
formerly  known as  SpectraScan,  Inc.,  which is the successor by merger to PSC

increase and extend the credit  facilities  thereunder,  and amend certain other
covenants in the Credit  Agreement to reflect the current  circumstances  of the
Borrower.  In addition,  First Union National Bank desires to be terminated as a
Lender Party,  and the Borrower  desires,  and the other Lenders  agree,  to add
Citizens Bank of Massachusetts and HSBC Bank USA as Lender Parties.

         Subsection (e) thereto, as follows:

                  (e) The Borrower shall pay to the Administrative Agent for the
         account of each Lender  Party,  upon the  request of such Lender  Party
         through the  Administrative  Agent,  such amount or amounts as shall be
         sufficient  (in  the  reasonable  opinion  of  such  Lender  Party)  to
         compensate  it for any loss,  cost or expense  which such Lender  Party
         determines  is  attributable  to (i) any payment of a  Eurodollar  Rate
         Advance or  conversion  of a  Eurodollar  Rate  Advance to a Prime Rate
         Advance  made on a date  other  than the last day of the  corresponding
         Interest Period for such Eurodollar Rate Advance  (whether by reason of
         acceleration,  mandatory conversion or otherwise),  (ii) any failure by
         the Borrower to borrow a Eurodollar  Rate Advance on the date specified
         by Borrower's  written notice,  or (iii) any failure by the Borrower to
         pay a Eurodollar Rate Advance on the date for payment  specified in the
         Borrower's  written  notice.  Without  limiting  the  foregoing,   such
         compensation  shall  include an amount equal to the excess,  if any, of
         (i) the amount of interest  which  otherwise  would have accrued on the
         principal  amount so paid for the period from and including the date of
         such payment to but excluding  the last day of the Interest  Period for
         such  Eurodollar  Rate Advance at the  applicable  rate of interest for
         such Eurodollar  Rate Advance  provided for herein over (ii) the amount
         of interest (as reasonably determined by each Lender Party) such Lender
         Party would have bid in the London  interbank  market for United States
         Dollar  deposits for amounts  comparable to such  principal  amount and
         maturities  comparable to such period.  A  determination  of any Lender
         Party as to the  amounts  payable  pursuant to this  Subsection  (e) of
         Section 2.10 shall be conclusive absent manifest error.

         FOR VALUE RECEIVED,  the  undersigned,  PSC Scanning,  Inc., a Delaware

________________________  (the  "Lender")  for  the  account  of its  Applicable
Lending  Office  (as  defined  in the Credit  Agreement  referred  to below) the
principal  amount of the Term Advance (as defined  below) owing to the Lender by
the  Borrower  pursuant to the Credit  Agreement,  dated as of July 12, 1996 (as
amended,  supplemented  or otherwise  modified,  the "Credit  Agreement";  terms
defined  therein being used herein as therein  defined) among the Borrower,  the
Lender and certain other lender parties  thereto,  Fleet National Bank (formerly
known as Fleet Bank),  as Initial  Issuing  Bank,  and Fleet  National  Bank, as
Administrative  Agent for the Lender and such other lender parties, on the dates

specified in the Credit Agreement.

         Both  principal  and interest are payable in lawful money of the United

entitled to the benefits of, the Credit Agreement.  The Credit Agreement,  among
other  things,  (i)  provides for the making of a single term advance (the "Term

contains  provisions for  acceleration of the maturity hereof upon the happening
of certain stated events and also for prepayments on account of principal hereof
prior to the maturity  hereof upon the terms and conditions  therein  specified.
The obligations of the Borrower under this Promissory  Note, and the obligations
of the  other  Loan  Parties  under  the  Loan  Documents,  are  secured  by the
Collateral as provided in the Loan Documents.

         This  Promissory  Note shall be governed by and construed in accordance
with the laws of the State of New York.

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties hereto agree as follows:

                                    ARTICLE I

                              Definitions and Usage

hereby accepts such appointment, to act for the benefit of the Issuer and the

as of the applicable Add-on Consolidation Loan Funding Date) with respect to
each Financed Student Loan:

<PAGE>

            (a) the original fully executed copy of the note evidencing the
      Financed Student Loan (including the original loan application fully
      executed by the Borrower); and

            (b) any and all other documents and computerized records that the
      Servicer shall keep on file, in accordance with its customary procedures,
      relating to such Financed Student Loan or any Obligor with respect
      thereto.

            SECTION 2.02. Duties of Servicer as Custodian. (a) Safekeeping. The
Servicer shall maintain custody of the Student Loan Files for the benefit of the
Issuer and the Indenture Trustee on behalf of the Noteholders and any Swap
Counterparties and maintain such accurate and complete accounts, records and
computer systems pertaining to each Student Loan File as shall enable the Issuer
to comply with the Basic Documents. In performing its duties as custodian, the
Servicer shall act with reasonable care, using that degree of skill and
attention that the Servicer exercises with respect to the student loan files
relating to all comparable Student Loans that the Servicer services and shall
ensure that it complies with all applicable federal and state laws, including
the Higher Education Act, with respect thereto. The Servicer shall conduct, or
cause to be conducted, periodic audits of the Student Loan Files held by it
under this Agreement and of the related accounts, records and computer systems,
in such a manner as shall enable the Issuer, the Indenture Trustee or any Swap
Counterparties to verify the accuracy of the Servicer's record keeping. The
Servicer shall promptly report to the Issuer, the Indenture Trustee and any Swap
Counterparties any failure on its part to hold the Student Loan Files and
maintain its accounts, records and computer systems as herein provided and
promptly take appropriate action to remedy any such failure. Nothing herein
shall be deemed to require an initial review or any periodic review by the
Issuer, the Eligible Lender Trustee or the Indenture Trustee of the Student Loan
Files.

            (b) Maintenance of Records. The Servicer shall maintain each Student
Loan File at one of the locations specified in Schedule A to this Agreement or
at such other office as shall be specified by written notice to the Issuer, the

change in location. Upon reasonable prior notice of not less than three Business

any Swap Counterparties or their respective duly authorized representatives,
attorneys or auditors a list of locations of the Student Loan Files and the
related accounts, records and computer systems maintained by the Servicer.

            (c) Release of Documents. Upon instruction from the Indenture
Trustee, the Servicer shall, as soon as practicable, release any Student Loan
File to the Indenture Trustee, the Indenture Trustee's agent, or the Indenture
Trustee's designee, as the case may be, at such place or places as the Indenture
Trustee may designate.

            SECTION 2.03. Instructions; Authority To Act. The Servicer shall be
deemed to have received proper instructions with respect to the Student Loan

<PAGE>

            SECTION 2.04. Custodian's Indemnification. The Servicer as Custodian
shall pay for any actual loss, liability or expense, including reasonable
attorneys' fees, that may be imposed on, incurred by or asserted against the
Issuer, the Eligible Lender Trustee or the Indenture Trustee or any of their
officers, directors, employees and agents as a result of any improper act or
omission in any way relating to the maintenance and custody by the Servicer as
Custodian of the Student Loan Files as required by this Agreement where the
final determination that any such improper act or omission by the Servicer
resulted in such loss, liability or expense is established by a court of law, by
an arbitrator, or by way of settlement agreed to by the Servicer; provided,
however, that the amount of any liability with respect to any Financed Student
Loan shall not exceed the amount that would have been paid if such Student Loan
had been accepted and paid by the related Guarantor as a claim, and provided,
further, that the Servicer shall not be liable to the Eligible Lender Trustee
for any portion of any such amount resulting from the willful misfeasance, bad
faith or negligence of the Eligible Lender Trustee and the Servicer shall not be
liable to the Indenture Trustee for any portion of any such amount resulting
from the willful misfeasance, bad faith or negligence of the Indenture Trustee.
This provision shall not be construed to limit the Servicer's or any other
party's rights, obligations, liabilities, claims or defenses which arise as a
matter of law or pursuant to any other provision of this Agreement.

            SECTION 2.05. Effective Period and Termination. The appointment of
Loan Services as Custodian shall become effective as of the Closing Date and
shall continue in full force and effect for so long as Loan Services shall
remain the Servicer hereunder. If all the rights and obligations of Loan
Services shall have been terminated under Section 6.01, the appointment of Loan
Services as Custodian shall be terminated simultaneously with the effectiveness
of such termination. As soon as practicable on or after any termination of such
appointment and in any event within ninety (90) days, Loan Services shall
deliver possession of the Student Loan Files to the Indenture Trustee or the
Indenture Trustee's agent at such place or places as the Indenture Trustee may
reasonably designate. Loan Services will continue to hold the Student Loan Files
as agent of the Indenture Trustee until the Student Loan Files are transferred.

                                   ARTICLE III

                  Administration and Servicing of Student Loans

            SECTION 3.01. Duties of Servicer. The Servicer, for the benefit of
the Issuer (to the extent provided herein), the Noteholders and any Swap
Counterparties, shall manage, service, administer and make collections on the
Financed Student Loans with reasonable care, using that degree of skill and
attention that the Servicer exercises with respect to all comparable Student
Loans that it services. Without limiting the generality of the foregoing or of
any other provision set forth in this Agreement and notwithstanding any other
provision to the contrary set forth herein, the Servicer shall manage, service,
administer and make collections with respect to the Financed Student Loans
(other than collection of any Interest Subsidy Payments and Special Allowance
Payments, which the Eligible Lender Trustee will perform on behalf of the Trust)
in accordance with, and otherwise comply with, all applicable federal and state
laws, including any applicable standards, guidelines and requirements of the
Higher Education Act and the applicable Guarantee Agreement, the failure to
comply with which would adversely affect the eligibility of

                                      -3-
<PAGE>

one or more of the Financed Student Loans for federal reinsurance or Interest
Subsidy Payments, Special Allowance Payments or Guarantee Payments or would have
an adverse effect on the Noteholders, any Swap Counterparties or the Company.
The Servicer also hereby acknowledges that its obligation to service the
Financed Student Loans includes all Consolidation Loans originated by the Issuer
during the Revolving Period, any Consolidation Loan supplemented from time to
time during and after the Revolving Period by the addition of the principal
balance of any related Add-on Consolidation Loan, any Qualified Substitute
Student Loans conveyed to the Issuer pursuant to Section 3.02 of the Loan Sale
Agreement and those Prefunded Loans, New Loans and Serial Loans conveyed to the
Eligible Lender Trustee on behalf of the Trust pursuant to Section 2.02 of the
Loan Sale Agreement and the related Transfer Agreement, a copy of which shall be
delivered to the Servicer by the Seller promptly upon execution thereof;
provided, however, that any failure by the Seller to so deliver a Transfer
Agreement shall not affect the Servicer's obligations hereunder to service all
the Financed Student Loans.

      The Servicer's duties shall include collection and posting of all
payments, responding to inquiries of borrowers on such Financed Student Loans,
monitoring borrowers' status, making required disclosures to borrowers,
investigating delinquencies, sending payment coupons to borrowers and otherwise
establishing repayment terms, reporting tax information to borrowers, if
applicable, accounting for collections and furnishing monthly and annual
statements with respect thereto to the Administrator. Subject to the provisions
of Section 3.02, the Servicer shall follow its customary standards, policies and
procedures in performing its duties as Servicer. Without limiting the generality
of the foregoing, the Servicer is authorized and empowered to execute and
deliver, on behalf of itself, the Issuer, the Eligible Lender Trustee, the
Indenture Trustee, the Company and the Noteholders or any of them, instruments
of satisfaction or cancellation, or partial or full release or discharge, and
all other comparable instruments, with respect to such Financed Student Loans;
provided, however, that the Servicer agrees that it will not (a) permit any
rescission or cancellation of a Financed Student Loan except as ordered by a
court of competent jurisdiction or governmental authority or as otherwise
consented to in writing by the Eligible Lender Trustee and the Indenture Trustee
or (b) reschedule, revise, defer or otherwise compromise with respect to
payments due on any Financed Student Loan except pursuant to any applicable
Deferral or Forbearance periods or otherwise in accordance with all applicable
standards, guidelines and requirements with respect to the servicing of the
Financed Student Loans; and provided, further, that the Servicer shall not agree
to any decrease of the interest rate on, or the principal amount payable with
respect to, any Financed Student Loan.

      The Servicer, for the benefit of the Issuer (to the extent provided
herein) and the Indenture Trustee on behalf of the Noteholders, shall promptly
and routinely furnish the Eligible Lender Trustee and the Indenture Trustee with
copies of all material reports, records, and other documents and data as
required by this Agreement or as may otherwise be required by the Higher
Education Act. All material correspondence received by the Servicer relating to
individual Student Loans shall be maintained in microcopy form or in summary
form in an automated history file established by the Servicer. The Servicer
shall furnish in good condition all forms and supplies as specified in this
Agreement and any Schedules hereto. The Eligible Lender Trustee and the
Indenture Trustee may transmit Financed Student Loan account data to the
Servicer on these forms or by any other mutually acceptable means. In performing
its duties hereunder, the Servicer will be guided by and comply with the Higher
Education Act and

                                      -4-
<PAGE>

applicable requirements of the related Guarantor. The Servicer agrees to produce
a clear and precise audit trail for each Financed Student Loan and to comply
with such other reporting, servicing, and operating standards as are contained
in this Agreement.

      The Eligible Lender Trustee on behalf of the Issuer hereby grants a power
of attorney and all necessary authorization to the Servicer to maintain any and
all collection procedures with respect to the Financed Student Loans, including
filing, pursuing and recovering claims against the Guarantors for Guarantee
Payments and taking any steps to enforce such Financed Student Loans such as
commencing a legal proceeding to enforce a Financed Student Loan in the name of
the Issuer, the Eligible Lender Trustee, the Indenture Trustee, the Company or
the Noteholders. The Eligible Lender Trustee or the Indenture Trustee shall upon
the written request of the Servicer or the Administrator furnish the Servicer or
the Administrator with any other powers of attorney and other documents
reasonably necessary or appropriate to enable the Servicer or the Administrator
to carry out their servicing and administrative duties hereunder.

            SECTION 3.02. Collection of Student Loan Payments. (a) The Servicer
shall make reasonable efforts (including all efforts that may be specified under
the Higher Education Act or any Guarantee Agreement) to collect all payments
called for under the terms and provisions of the Financed Student Loans as and
when the same shall become due and shall follow such collection procedures as it
follows with respect to all comparable Student Loans that it services. The
Servicer shall allocate collections with respect to the Financed Student Loans
between principal and interest in accordance with the terms of each such loan.
The Servicer may in its discretion waive any late payment charge or any other
fees that may be collected in the ordinary course of servicing a Financed
Student Loan.

            (b) The Servicer shall make reasonable efforts to claim, pursue and
collect all Guarantee Payments from the Guarantors pursuant to the Guarantee
Agreements with respect to any of the Financed Student Loans as and when the
same shall become due and payable, shall comply with the Higher Education Act
and all other applicable laws and agreements with respect to claiming, pursuing
and collecting such payments and shall follow such practices and procedures as
it follows with respect to all comparable guarantee agreements and student loans
that it services. In connection therewith, the Servicer is hereby authorized and
empowered to convey to the related Guarantor the note and the related Student
Loan File representing any Financed Student Loan in connection with submitting a
claim to the applicable Guarantor for a Guarantee Payment in accordance with the
terms of the applicable Guarantee Agreement.

            (c) The Eligible Lender Trustee shall, with the assistance of the
Servicer as set forth below and on behalf of the Issuer, make reasonable efforts
to claim, pursue and collect all Interest Subsidy Payments and Special Allowance
Payments from the Department with respect to any of the Financed Student Loans
as and when the same shall become due and payable, shall comply with all
applicable laws and agreements with respect to claiming, pursuing and collecting
such payments and shall follow such practices and procedures as the Servicer
follows with respect to Student Loans serviced by it. All amounts so collected
by the Eligible Lender Trustee with respect to Financed Student Loans (net, for
the first Collection Period, of interest accrued prior to the Cutoff Date that
is not to be capitalized) shall constitute Monthly Available Funds for the
applicable Monthly Collection Period and Available Funds for the applicable
Collection

                                      -5-
<PAGE>

Period, and shall be deposited into the Collection Account in accordance with
Section 4.01. In connection therewith, the Servicer shall prepare and file with
the Department on a timely basis all claims forms and other documents and
filings necessary or appropriate in connection with the claiming of Interest
Subsidy Payments and Special Allowance Payments on behalf of the Eligible Lender
Trustee and shall otherwise assist the Eligible Lender Trustee in pursuing and
collecting such Interest Subsidy Payments and Special Allowance Payments from
the Department. The Eligible Lender Trustee shall upon the written request of
the Servicer furnish the Servicer with any power of attorney and other documents
reasonably necessary or appropriate to enable the Servicer to prepare and file
such claims forms and other documents and filings.

      The Eligible Lender Trustee may permit trusts, other than the Trust,
established by the Seller to securitize student loans to use the Department
lender identification number applicable to the Trust. In such event, the
Eligible Lender Trustee may claim and collect Interest Subsidy Payments and
Special Allowance Payments with respect to Financed Student Loans in the Trust
and student loans in such other trusts using such common lender identification
number. Notwithstanding anything herein or in the Basic Documents to the
contrary, any amounts assessed against payments (including, but not limited to,
Interest Subsidy Payments and Special Allowance Payments) due from the
Department to any such other trust using such common lender identification
number as a result of amounts (including, but not limited to, Consolidation
Fees) owing to the Department from the Trust will be deemed for all purposes
hereof and of the Basic Documents (including for purposes of determining amounts
paid by the Department with respect to the student loans in the Trust and such
other trust) to have been assessed against the Trust and shall be deducted by
the Eligible Lender Trustee or the Servicer and paid to such other trust from
any collections made by them which would otherwise have been payable to the
Collection Account for the Trust. If so specified in the servicing agreement
applicable to any such other trust, any amounts assessed against payments due
from the Department to the Trust as a result of amounts owing to the Department
from such other trust using such common lender identification number will be
deemed to have been assessed against such other trust and will be deducted by
the Eligible Lender Trustee or the Servicer from any collections made by them
which would otherwise be payable to the collection account for such other trust
and paid to the Trust.

            SECTION 3.03. Realization upon Student Loans. For the benefit of the
Issuer, the Servicer shall use reasonable efforts consistent with its customary
servicing practices and procedures and including all efforts that may be
specified under the Higher Education Act or the applicable Guarantee Agreement
in its servicing of any delinquent Financed Student Loans.

            SECTION 3.04. No Impairment. The Servicer shall not impair the
rights of the Issuer, the Eligible Lender Trustee, the Indenture Trustee, the
Company, the Noteholders or any Swap Counterparties in the Financed Student
Loans.

            SECTION 3.05. Purchase of Student Loans; Reimbursement. (a) Upon the
discovery by the Servicer, the Eligible Lender Trustee, the Indenture Trustee or
the Seller of any breach pursuant to Sections 3.01, 3.02, 3.03 or 3.04 hereof,
the party discovering the breach shall give prompt written notice to the others.
If the breach is not cured within sixty (60) days after the Servicer becomes
aware or receives written notice (whichever is earlier) of such breach, the

                                      -6-
<PAGE>

Servicer shall purchase or arrange for the purchase of any Student Loan in which
the interests of the Noteholders, the Issuer, the Indenture Trustee, the
Eligible Lender Trustee or any Swap Counterparties are materially and adversely
affected by such breach as of the first day succeeding the end of such 60-day
period that is the last day of a Monthly Collection Period (it being understood
that any such breach that does not affect the related Guarantor's obligation to
guarantee payment of such Student Loan will not be considered to have a material
adverse effect for this purpose and it being further understood that any dispute
as to whether such Guarantor's obligation has been so affected so as to create
such a material adverse effect, shall be resolved, for so long as the Notes are
Outstanding, by the Indenture Trustee, whose determination shall be dispositive,
and after the Notes are no longer Outstanding, by the Eligible Lender Trustee,
whose determination shall then be dispositive); provided, however, that during
each 12-month period following the Cutoff Date or an anniversary of the Cutoff
Date (each, a "Servicer Liability Period"), the Servicer will be obligated to
purchase Student Loans only to the extent its total liability incurred during
the then current Servicer Liability Period for such purchases and any other
liabilities under this Agreement exceeds an amount (the "Servicer Liability
Limit") equal to 0.15% of the principal balances of the Financed Student Loans
outstanding as of the Cutoff Date or, after the first anniversary of the Cutoff
Date, as of the preceding July 31.

            (b) In consideration of the purchase of any such Student Loan
pursuant to this Section 3.05, the Servicer shall remit, in the manner specified
in Section 4.01, the Purchase Amount and the Issuer shall execute such
assignments and other documents reasonably requested by the Servicer in order to
effect the transfer of such Student Loan to the Servicer or its designee;
provided, however, that the Servicer's total liability for losses for rejected
claims by the Guarantors for any Financed Student Loan based on any breach
pursuant to Sections 3.01, 3.02, 3.03 or 3.04 hereof will not exceed that amount
which the related Guarantor would have been obligated to pay with respect to
such loan had its obligation to guarantee payment thereof not been affected by
the Servicer's breach. Subject to Section 5.02, the exclusive remedy of the
Noteholders, the Issuer, the Indenture Trustee, and the Eligible Lender Trustee
and the entire liability of Servicer for such a breach shall be limited to
requiring the Servicer to purchase Financed Student Loans pursuant to this
Section 3.05.

            SECTION 3.06. Servicing Fee. The Servicing Fee for each calendar
month (the "Servicing Fee") shall be equal to the lesser of (a) one-twelfth of
0.60% or such larger percentage approved by the Rating Agencies, not to exceed
1.00% (or of 0.50% with respect to any calendar month beginning with January
2010) of the aggregate principal balances of the Financed Student Loans
outstanding as of the last day of the preceding calendar month and (b) the sum
of (i) one-twelfth of the In-School Percentage of the principal balance of each
Billing Account relating to a Financed Student Loan as of the last day of the
preceding calendar month which was an In-School Loan on such date or, if the
average principal balance of Billing Accounts relating to In-School Loans as of
such date was $2,500 or less, $1.50 per Billing Account, (ii) one-twelfth of the
GRDF Percentage of the principal balance as of the last day of the preceding
calendar month of each Billing Account relating to a Financed Student Loan which
was a Grace, Repayment, Deferral or Forbearance Student Loan as of such date or,
if the average principal balance of such Billing Accounts as of such date was
$3,000 or less, $3.00 per Billing Account, (iii) a fee of $1.00 for each
notification sent by the Servicer during the preceding calendar month on behalf
of the Trust to a borrower providing information to such borrower with

                                      -7-
<PAGE>

respect to Federal Consolidation Loan programs, (iv) a one-time fee of $75.00
for each Federal Consolidation Loan originated by the Eligible Lender Trustee on
behalf of the Trust during the preceding calendar month, (v) a fee of $25.00 for
each Financed Student Loan for which, during the preceding calendar month, claim
documentation was completed and provided to the Guarantor or for which the
Servicer performed bankruptcy or ineligible Billing Account processing (that, in
the case of ineligible Billing Account processing, resulted in a demand letter
being sent to the borrower), in each case as required by the claims processing
requirements of the Guarantor, (vi) a fee of $.05 per Financed Student Loan for
storing and warehousing the applicable loan documentation for each such loan
during the preceding calendar month, (vii) a one-time fee of $0.40 for each
Billing Account transferred by the Seller to the Trust during the preceding
calendar month, (viii) a fee equal to one-twelfth of the product of (A) the
aggregate outstanding principal balance of the Financed Student Loans as of the
last day of the preceding calendar month and (B) .05%, which fee will be payable
so long as 34 C.F.R. ss. 682.413 or any successor section remains in effect and
(ix) a fee of $70.00 per hour for system development requests made by the
Eligible Lender Trustee on behalf of the Trust and provided by the Servicer
during the preceding calendar month. For purposes of making the determinations
set forth in clauses (i) and (ii) of the preceding sentence, the "In-School
Percentage" and "GRDF Percentage" shall each be determined based on the average
principal balance of the Billing Accounts relating to the In-School Loans and
the Billing Accounts relating to the Grace, Repayment, Deferral and Forbearance
Loans, respectively, as of the last day of the preceding calendar month, as
follows:

Average Principal         In-School        Average Principal           GRDF
    Balance               Percentage            Balance              Percentage
-----------------        ------------      -----------------        ------------

$2,501 - $3,000             0.625%          $3,001 - $3,400            1.100%
$3,001 - $3,500             0.525%          $3,401 - $3,900            0.950%
$3,501 - $4,000             0.450%          $3,901 - $4,400            0.830%
$4,001 - $4,750             0.375%          $4,401 - $4,800            0.740%
$4,751 - $5,500             0.310%          $4,801 - $5,400            0.650%
$5,501 - $6,250             0.260%          $5,401 - $6,000            0.575%
$6,251 and above            0.230%          $6,001 - $6,600            0.510%
                                            $6,601 - $7,200            0.475%
                                            $7,201 - $10,000           0.450%
                                            $10,001 - $13,000          0.350%
                                            $13,001 and above          0.300%

      The Servicing Fee (together with any portion of the Servicing Fee that
remains unpaid from prior Monthly Payment Dates) will be payable on each Monthly
Payment Date and will be paid solely out of Monthly Available Funds in the case
of each Monthly Payment Date that is not a Quarterly Payment Date (and out of
Available Funds in the case of each Quarterly Payment Date) and amounts on
deposit in the Reserve Account on such Monthly Payment Date (including each
Quarterly Payment Date) as provided in Sections 2(d)(iv)(A), 2(d)(v)(A) and
2(e)(iv)(A) of the Administration Agreement. To the extent that, for any Monthly
Payment Date, the Servicing Fee is the amount calculated as described in clause
(a) of the first sentence of the preceding paragraph, then an amount (the
"Servicing Fee Shortfall") equal to the excess of the amount

                                      -8-
<PAGE>

described in clause (b) of such sentence over the amount described in clause (a)
of such sentence shall be payable on the next succeeding Quarterly Payment Date
(or if such Monthly Payment Date is also a Quarterly Payment Date, on such
Quarterly Payment Date) from any remaining Reserve Account Excess as provided in
Section 2(e)(ii) of the Administration Agreement. To the extent such remaining
Available Funds are insufficient to pay the Servicing Fee Shortfall on any
Distribution Date, the Seller shall be required to pay any unpaid Servicing Fee
Shortfall directly to the Servicer out of its own funds. The Servicer will be
obligated to perform its servicing obligations whether or not it receives any
amounts in respect of Servicing Fee Shortfalls.

            SECTION 3.07. Servicer's Report. On or before the fifteenth day of
each month (or, if any such day is not a Business Day, on the next succeeding
Business Day), the Servicer shall deliver to the Administrator a servicer's
report with respect to the preceding calendar month containing all information
necessary for the Administrator to prepare the Administrator's Certificate,
referred to in Section 2(b)(ii) of the Administration Agreement, covering such
preceding calendar month.

            SECTION 3.08. Annual Statement as to Compliance; Notice of Default.
(a) The Servicer shall deliver to the Eligible Lender Trustee, the Indenture
Trustee and any Swap Counterparties (with a copy to the Seller), on or before
April 30 of each year beginning April 30, 2001, an Officers' Certificate of the
Servicer, dated as of December 31 of the preceding year, stating that (i) a
review of the activities of the Servicer during the preceding 12-month period
(or, in the case of the first such certificate, during the period from the
Closing Date to December 31, 2000 or, as specified below, to September 30, 2000)
and of its performance has been made under such officers' supervision and (ii)
to the best of such officers' knowledge, based on such review, the Servicer has
fulfilled all its obligations under this Agreement in all material respects
throughout such year (or in the case of the first such Officers' Certificate,
such shorter period) or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officers and the
nature and status thereof; provided, however, that, at the option of the
Servicer, the Servicer may date the initial such Officers' Certificate as of
September 30, 2000, and, in such case, shall deliver such Officer's Certificate
on or before December 31, 2000 and thereafter shall deliver such Officer's
Certificate, dated as of September 30 of each succeeding year, on or before
December 31 of such year. The Indenture Trustee shall send a copy of each such
Officers' Certificate and each report referred to in this Section 3.08 to the
Rating Agencies. A copy of each such Officers' Certificate and each report
referred to in this Section 3.08 may be obtained by any Noteholder or Note Owner
by a request in writing to the Eligible Lender Trustee addressed to its
Corporate Trust Office, together with evidence satisfactory to the Eligible
Lender Trustee that such Person is one of the foregoing parties. Upon the
telephone request of the Eligible Lender Trustee, the Indenture Trustee will
promptly furnish the Eligible Lender Trustee a list of Noteholders as of the
date specified by the Eligible Lender Trustee.

            (b) The Servicer shall deliver to the Eligible Lender Trustee, the
Indenture Trustee, the Seller, any Swap Counterparties and the Rating Agencies,
promptly after having obtained knowledge thereof, but in no event later than
five Business Days thereafter, written notice in an Officers' Certificate of the
Servicer of any event which with the giving of notice or lapse of time, or both,
would become a Servicer Default under Section 6.01 or would cause the Servicer
to fail to meet any Rating Agency Condition.

                                      -9-

            SECTION 3.09. Annual Independent Certified Public Accountants'
Report. The Servicer shall cause a firm of independent certified public
accountants, which may also render other services to the Servicer, the Seller or
their Affiliates, to deliver to the Eligible Lender Trustee, the Indenture
Trustee and any Swap Counterparties (with a copy to the Seller) within 180 days
of the end of the Servicer's regular fiscal-year ended September 30 or
calendar-year audit period, an audit report that encompasses the Servicer's
portion of the annual Lender Audit (as defined in the Higher Education Act), or
any successor thereto, as required of a lender under the Higher Education Act,
for the preceding year (or, in the case of the first such report, during the
period from the Closing Date to December 31, 2000 or, as the case may be, to
September 30, 2000). The Indenture Trustee shall send a copy of each such report
to the Rating Agencies.

            Such report will also indicate that the firm is independent of the
Servicer within the meaning of the Code of Professional Ethics of the American
Institute of Certified Public Accountants.

            SECTION 3.10. Access to Certain Documentation and Information
Regarding Financed Student Loans. Upon at least three Business Days' prior
notice, the Servicer shall provide the Noteholders access to the Student Loan
Files in such cases where the Noteholders shall be required by applicable
statutes or regulations to review such documentation, as demonstrated by
evidence satisfactory to the Servicer in its reasonable judgment. Access shall
be afforded without charge, but only upon reasonable request and during the
normal business hours at the respective offices of the Servicer. Nothing in this
Section shall affect the obligation of the Servicer to observe any applicable
law prohibiting disclosure of information regarding the Obligors and the failure
of the Servicer to provide access to information as a result of such obligation
shall not constitute a breach of this Section.

            SECTION 3.11. Servicer Expenses. The Servicer shall be required to
pay all expenses incurred by it in connection with its activities hereunder,
including fees and disbursements of independent accountants, taxes imposed on
the Servicer, and expenses incurred in connection with distributions and reports
to the Administrator or the Noteholders, as the case may be.

            SECTION 3.12. Appointment of Subservicer. The Servicer may at any
time appoint a subservicer to perform all or any portion of its obligations as
Servicer hereunder; provided, however, that the Rating Agency Condition shall
have been satisfied in connection therewith; and provided, further, that the
Servicer shall remain obligated and be liable to the Issuer, the Eligible Lender
Trustee, the Indenture Trustee and the Noteholders for the servicing and
administering of the Financed Student Loans in accordance with the provisions
hereof without diminution of such obligation and liability by virtue of the
appointment of such subservicer and to the same extent and under the same terms
and conditions as if the Servicer alone were servicing and administering the
Financed Student Loans. The fees and expenses of the subservicer shall be as
agreed between the Servicer and its subservicer from time to time and none of
the Issuer, the Eligible Lender Trustee, the Indenture Trustee or the
Noteholders shall have any responsibility therefor.

within two Business Days of receipt of freely available funds therefor):

            (i) all identifiable payments received by the Servicer by or on

      aggregate Purchase Amount with respect to Purchased Student Loans and all
      other amounts to be paid by the Seller under Section 3.02 and 5.01 of the
      Loan Sale Agreement when such amounts are due, as provided in Section 3.03
      of the Loan Sale Agreement.

            (vii) The Indenture Trustee, at the written direction of the
      Administrator, shall withdraw from the Collateral Reinvestment Account and
      deposit into the Collection Account on each Determination Date during the
      Revolving Period, an amount equal to the Capitalized Interest Amount for
      the preceding Collection Period, as provided in Section 2(f) of the
      Administration Agreement.

            (viii) The Indenture Trustee, at the written direction of the
      Administrator, shall withdraw from the Collateral Reinvestment Account and
      deposit into the Collection Account on any date during the Revolving
      Period specified by the Administrator, such amounts as the Administrator
      may determine are needed to make required distributions from Monthly
      Available Funds or Available Funds, as the case may be, on Monthly Payment
      Dates.

                                  The Servicer

            SECTION 5.01. Representations of Servicer. The Servicer makes the
following representations on which the Issuer is deemed to have relied in
acquiring (through the Eligible Lender Trustee) the Financed Student Loans and
appointing the Servicer as servicer hereunder. The representations speak as of
the execution and delivery of this Agreement and as of the Closing Date in the
case of the Initial Financed Student Loans, and will be deemed to speak as of
the applicable Transfer Date, in the case of Prefunded Loans, New Loans and
Serial Loans, as of the date of the relevant Assignment in the case of any
Qualified Substitute Student Loan, as of the date of origination in the case of
any Consolidation Loan added to the Trust during the Revolving Period and as of
the applicable Add-on Consolidation Loan Funding Date in the case of any
Consolidation Loan the principal balance of which has been increased by the
principal balance of a related Add-on Consolidation Loan, but shall survive the
sale, transfer and assignment of the Financed Student Loans to the Eligible
Lender Trustee on behalf of the Issuer (and the origination of such
Consolidation Loans) and the pledge thereof to the Indenture Trustee pursuant to
the Indenture.

            (a) Organization and Good Standing. The Servicer is duly organized
      and validly existing as a corporation in good standing under the laws of
      the State of Delaware, with the power and authority to own its properties
      and to conduct its business as such properties are currently owned and
      such business is currently conducted, and has the legal right to service
      the Financed Student Loans.

            (b) Power and Authority of the Servicer. The Servicer has the
      corporate power and authority to execute and deliver this Agreement and to
      carry out its terms, and the execution, delivery and performance of this
      Agreement have been duly authorized by the Servicer by all necessary
      corporate action.

            (c) Binding Obligation. This Agreement constitutes a legal, valid
      and binding obligation of the Servicer, enforceable in accordance with its
      terms, subject to applicable bankruptcy, insolvency, reorganization and
      similar laws relating to creditors' rights generally and subject to
      general principles of equity.

            (d) No Violation. The consummation of the transactions contemplated
      by this Agreement and the fulfillment of the terms hereof or thereof do
      not conflict with, result in any breach of any of the terms and provisions
      of, or constitute (with or without notice or lapse of time or both) a
      default under, the certificate of incorporation or by-laws of the
      Servicer, or any indenture, agreement or other instrument to which the
      Servicer is a party or by which it shall be bound; or result in the
      creation or imposition of any Lien upon any of its properties pursuant to
      the terms of any such indenture, agreement or other instrument; or violate
      any law or, to the knowledge of the Servicer, any order, rule or
      regulation applicable to the Servicer of any court or of any federal or
      state regulatory body, administrative agency or other governmental
      instrumentality having jurisdiction

                                      -12-
<PAGE>

      over the Servicer or its properties. Performance by the Servicer of its
      servicing duties with respect to the Financed Student Loans, and
      compliance by the Servicer with the terms of this Agreement, will not
      result in the loss of any Guarantee Payments by the Trust or any
      reinsurance payments with respect to any Financed Student Loan by the
      applicable Guarantor.

            (e) No Proceedings. There are no proceedings or investigations
      pending against the Servicer or, to its best knowledge, threatened against
      the Servicer, before any court, regulatory body, administrative agency or
      other governmental instrumentality having jurisdiction over the Servicer
      or its properties: (i) asserting the invalidity of this Agreement or any
      of the other Basic Documents to which the Servicer is a party, (ii)
      seeking to prevent the issuance of the Notes or the consummation of any of
      the transactions contemplated by this Agreement, or any of the other Basic
      Documents, (iii) seeking any determination or ruling that could reasonably
      be expected to have a material and adverse effect on the performance by
      the Servicer of its obligations under, or the validity or enforceability
      of, this Agreement, any of the other Basic Documents or the Notes or (iv)
      seeking to affect adversely the federal or state income tax attributes of
      the Issuer or the Notes.

            (f) All Consents. All authorizations, consents, licenses, orders or
      approvals of or registrations or declarations with any court, regulatory
      body, administrative agency or other government instrumentality required
      to be obtained, effected or given by the Servicer in connection with the
      execution and delivery by the Servicer of this Agreement and the
      performance by the Servicer of its duties contemplated by this Agreement
      have in each case been duly obtained, effected or given and are in full
      force and effect.

            SECTION 5.02. Indemnities of Servicer. (a) The Servicer shall be
liable in accordance herewith only to the extent of the obligations specifically
undertaken by the Servicer under this Agreement.

            The Servicer shall pay for any loss, liability or expense, including
reasonable attorneys' fees, that may be imposed on, incurred by or asserted
against the Issuer, the Eligible Lender Trustee, the Indenture Trustee, the
Seller, the Administrator or the Noteholders or any of the officers, directors,
employees and agents of the Issuer, the Eligible Lender Trustee, the Indenture
Trustee, the Administrator or the Seller to the extent that such loss, liability
or expense arose out of, or was imposed upon any such Person through, the
negligence, willful misfeasance or bad faith of the Servicer in the performance
of its obligations and duties under this Agreement or by reason of the reckless
disregard of its obligations and duties under this Agreement, where the final
determination that any such loss, liability or expense arose out of, or was
imposed upon any such Person through, any such negligence, willful misfeasance,
bad faith or recklessness on the part of the Servicer is established by a court
of law, by an arbitrator or by way of settlement agreed to by the Servicer;
provided, however, that the Servicer's obligation arising under this Section
5.02 shall apply only to the extent that the sum of such obligation and any
other liabilities of the Servicer under this Agreement exceeds the Servicer
Liability Limit for any Servicer Liability Period (as such terms are defined in
Section 3.05). Notwithstanding the foregoing, if the Servicer is rendered
unable, in whole or in part, by a force outside the control of

                                      -13-
<PAGE>

the parties hereto (including acts of God, acts of war, fires, earthquakes and
other disasters) to satisfy its obligations under this Agreement, the Servicer
shall not be deemed to have breached any such obligation upon delivery of
written notice of such event to the other parties hereto, for so long as the
Servicer remains unable to perform such obligation as a result of such event.

            For purposes of this Section, in the event of the termination of the
rights and obligations of Loan Services as Servicer pursuant to Section 6.01, or
a resignation by such Servicer pursuant to this Agreement, such Servicer shall
be deemed to be the Servicer pending appointment of a successor Servicer
pursuant to Section 6.02.

            Liability of the Servicer under this Section shall survive the
resignation or removal of the Eligible Lender Trustee or the Indenture Trustee
or the termination of this Agreement and shall include reasonable fees and
expenses of counsel and expenses of litigation. If the Servicer shall have made
any indemnity payments pursuant to this Agreement and the Person to or on behalf
of whom such payments are made thereafter collects any of such amounts from
others, such Person shall promptly repay such amounts to the Servicer, without
interest.

            (b) Except with respect to liabilities relating to rejected claims
by the Guarantors, the Seller agrees to indemnify and hold harmless the Servicer
from any liability incurred by the Servicer under subsection (a) above as a
result of the Servicer's ordinary negligence.

            SECTION 5.03. Merger or Consolidation of, or Assumption of the
Obligations of, Servicer. The Servicer hereby agrees that, upon (a) any merger
or consolidation of the Servicer into another Person, (b) any merger or
consolidation to which the Servicer shall be a party resulting in the creation
of another Person or (c) any Person succeeding to the properties and assets of
the Servicer substantially as a whole, the Servicer shall (i) cause such Person
(if other than the Servicer) to execute an agreement of assumption to perform
every obligation of the Servicer hereunder, (ii) deliver to the Eligible Lender
Trustee, the Indenture Trustee and any Swap Counterparties an Officers'
Certificate and an Opinion of Counsel each stating that such consolidation,
merger or succession and such agreement of assumption comply with this Section
and that all conditions precedent provided for in this Agreement relating to
such transaction have been complied with, (iii) cause the Rating Agency
Condition to have been satisfied with respect to such transaction and (iv) cure
any existing Servicer Default or any continuing event which, after notice or
lapse of time or both, would become a Servicer Default. Upon compliance with the
foregoing requirements, such Person shall be the successor to the Servicer under
this Agreement without further act on the part of any of the parties to this
Agreement. Notwithstanding anything herein to the contrary, compliance with
clauses (i), (ii), (iii) and (iv) above shall be conditions to the consummation
of any of the transactions referred to in clause (a), (b) or (c) above.

            SECTION 5.04. Limitation on Liability of Servicer and Others.
Neither the Servicer nor any of the directors, officers, employees or agents of
the Servicer shall be under any liability to the Issuer or the Noteholders,
except as provided under this Agreement, for any action taken or for refraining
from the taking of any action pursuant to this Agreement or for errors in
judgment; provided, however, that this provision shall not protect the Servicer
or any such

                                      -14-
<PAGE>

Person against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence in the performance of duties or by
reason of reckless disregard of obligations and duties under this Agreement. The
Servicer and any director, officer, employee or agent of the Servicer may rely
in good faith on any document of any kind prima facie properly executed and
submitted by any person respecting any matters arising under this Agreement.

            Except as provided in this Agreement, the Servicer shall not be
under any obligation to appear in, prosecute or defend any legal action that
shall not be incidental to its duties to service the Student Loans in accordance
with this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, that the Servicer may undertake any reasonable
action that it may deem necessary or desirable in respect of this Agreement and
the other Basic Documents and the rights and duties of the parties to this
Agreement and the other Basic Documents and the interests of the Noteholders
under the Indenture.

            SECTION 5.05. Loan Services Not to Resign as Servicer. Subject to
the provisions of Section 5.03, Loan Services shall not resign from the
obligations and duties hereby imposed on it as Servicer under this Agreement
except upon determination that the performance of its duties under this
Agreement shall no longer be permissible under applicable law. Notice of any
such determination permitting the resignation of Loan Services shall be
communicated to the Eligible Lender Trustee, the Indenture Trustee, the Rating
Agencies and any Swap Counterparties at the earliest practicable time (and, if
such communication is not in writing, shall be confirmed in writing at the
earliest practicable time) and any such determination shall be evidenced by an
Opinion of Counsel to such effect delivered to the Eligible Lender Trustee, the
Indenture Trustee and any Swap Counterparties concurrently with or promptly
after such notice. No such resignation shall become effective until the
Indenture Trustee or a Successor Servicer shall have assumed the
responsibilities and obligations of Loan Services in accordance with Section
6.02.

                                   ARTICLE VI

                                     Default

            SECTION 6.01. Servicer Default. If any one of the following events
(each, a "Servicer Default") shall occur and be continuing:

            (a) any failure by the Servicer to deliver to the Indenture Trustee
      for deposit in any of the Trust Accounts any payment required by the Basic
      Documents, which failure continues unremedied for three Business Days
      after written notice of such failure is received by the Servicer from the
      Eligible Lender Trustee, the Indenture Trustee or the Administrator or
      after discovery of such failure by an officer of the Servicer; or

            (b) any failure by the Servicer duly to observe or to perform in any
      material respect any other covenants or agreements of the Servicer set
      forth in this Agreement or any other Basic Document, which failure shall
      (i) materially and adversely affect the rights of Noteholders or any Swap
      Counterparties and (ii) continue unremedied for a period of thirty (30)
      days after the date of discovery of such failure by an officer of the
      Servicer or on which written notice of such failure, requiring the same to
      be remedied,

                                      -15-
<PAGE>

      shall have been given (A) to the Servicer, by the Indenture Trustee, the
      Eligible Lender Trustee or (B) to the Servicer, the Indenture Trustee, the
      Administrator and the Eligible Lender Trustee by Noteholders representing
      not less than 25% of the Outstanding Amount of the Notes; or

            (c) any limitation, suspension or termination by the Department of
      the Servicer's eligibility to service Student Loans which materially and
      adversely affects its ability to service the Financed Student Loans; or

            (d) an Insolvency Event occurs with respect to the Servicer;

then, and in each and every case, so long as the Servicer Default shall not have
been remedied, either the Indenture Trustee or the Noteholders of Notes
evidencing not less than 75% of the Outstanding Amount of the Notes by notice
then given in writing to the Servicer (and to the Indenture Trustee and the
Eligible Lender Trustee if given by the Noteholders) may terminate all the
rights and obligations (other than the obligations set forth in Section 5.02) of
the Servicer under this Agreement. On or after the receipt by the Servicer of
such written notice, all authority and power of the Servicer under this
Agreement, whether with respect to the Notes, the Financed Student Loans or
otherwise, shall, without further action, pass to and be vested in the Indenture
Trustee or such successor Servicer as may be appointed under Section 6.02; and,
without limitation, the Indenture Trustee and the Eligible Lender Trustee are
hereby authorized and empowered to execute and deliver, for the benefit of the
predecessor Servicer, as attorney-in-fact or otherwise, any and all documents
and other instruments, and to do or accomplish all other acts or things
necessary or appropriate to effect the purposes of such notice of termination,
whether to complete the transfer and endorsement of the Financed Student Loans
and related documents, or otherwise. The predecessor Servicer shall cooperate
with the successor Servicer, the Indenture Trustee and the Eligible Lender
Trustee in effecting the termination of the responsibilities and rights of the
predecessor Servicer under this Agreement, including the transfer to the
successor Servicer for administration by it of all cash amounts that shall at
the time be held by the predecessor Servicer for deposit, or shall thereafter be
received by it with respect to a Financed Student Loan. All reasonable costs and
expenses (including attorneys' fees) incurred in connection with transferring
the Student Loan Files to the successor Servicer and amending this Agreement and
any other Basic Documents to reflect such succession as Servicer pursuant to
this Section shall be paid by the predecessor Servicer upon presentation of
reasonable documentation of such costs and expenses. Upon receipt of notice of
the occurrence of a Servicer Default, the Eligible Lender Trustee shall give
notice thereof to the Rating Agencies.

            SECTION 6.02. Appointment of Successor. (a) Upon receipt by the
Servicer of notice of termination pursuant to Section 6.01, or the resignation
by the Servicer in accordance with the terms of this Agreement, the predecessor
Servicer shall continue to perform its functions as Servicer under this
Agreement, in the case of termination, only until the date specified in such
termination notice or, if no such date is specified in a notice of termination,
until receipt of such notice and, in the case of resignation, until the later of
(x) the date 120 days from the delivery to the Eligible Lender Trustee, and the
Indenture Trustee of written notice of such resignation (or written confirmation
of such notice) in accordance with the terms of this Agreement and (y) the date
upon which the predecessor Servicer shall become unable to act as Servicer as
specified in

                                      -16-
<PAGE>

the notice of resignation and accompanying Opinion of Counsel. In the event of
the termination hereunder of the Servicer, the Issuer shall appoint a successor
Servicer acceptable to the Indenture Trustee, and the successor Servicer shall
accept its appointment by a written assumption in form acceptable to the
Indenture Trustee and the Administrator. In the event that a successor Servicer
has not been appointed at the time when the predecessor Servicer has ceased to
act as Servicer in accordance with this Section, the Indenture Trustee without
further action shall automatically be appointed the successor Servicer and the
Indenture Trustee shall be entitled to the Servicing Fee. Notwithstanding the
above, the Indenture Trustee shall, if it shall be unwilling or legally unable
so to act, appoint or petition a court of competent jurisdiction to appoint, any
established institution the regular business of which shall include the
servicing of student loans, as the successor to the Servicer under this
Agreement; provided, however, that such right to appoint or to petition for the
appointment of any such successor Servicer shall in no event relieve the
Indenture Trustee from any obligations otherwise imposed on it under the Basic
Documents until such successor has in fact assumed such appointment.

            (b) Upon appointment, the successor Servicer (including the
Indenture Trustee acting as successor Servicer) shall be the successor in all
respects to the predecessor Servicer and shall be subject to all the
responsibilities, duties and liabilities placed on the predecessor Servicer that
arise thereafter or are related thereto and shall be entitled to an amount
agreed to by such successor Servicer (which shall not exceed the Servicing Fee,
unless such compensation arrangements will not result in a downgrading of the
Class A-1 Notes, the Class A-2 Notes or the Subordinate Notes by any Rating
Agency) and all the rights granted to the predecessor Servicer by the terms and
provisions of this Agreement.

            (c) The Servicer may not resign unless it is prohibited from serving
as such by law as evidenced by an Opinion of Counsel to such effect delivered to
the Indenture Trustee and the Eligible Lender Trustee. Notwithstanding the
foregoing or anything to the contrary herein or in the other Basic Documents,
the Indenture Trustee, to the extent it is acting as successor Servicer pursuant
hereto, shall be entitled to resign to the extent a qualified successor Servicer
has been appointed and has assumed all the obligations of the Servicer in
accordance with the terms of this Agreement and the other Basic Documents.

            SECTION 6.03. Notification to Noteholders and the Company. Upon any
termination of, or appointment of a successor to, the Servicer pursuant to this
Article VI, the Indenture Trustee shall give prompt written notice thereof to
Noteholders, the Administrator, the Company, the Eligible Lender Trustee and the
Rating Agencies (which, in the case of any such appointment of a successor,
shall consist of prior written notice thereof to the Rating Agencies).

            SECTION 6.04. Waiver of Past Defaults. The Noteholders of Notes
evidencing not less than a majority of the Outstanding Amount of the Notes may,
on behalf of all Noteholders, waive in writing any default by the Servicer in
the performance of its obligations hereunder, and any consequences thereof,
except a default in making any required deposits to or payments from any of the
Trust Accounts (or giving instructions regarding the same) in accordance with
this Agreement to the extent provided in such waiver. Upon any such waiver of a
past default, such default shall cease to exist, and any Servicer Default
arising therefrom shall

                                      -17-
<PAGE>

be deemed to have been remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereto.

                                   ARTICLE VII

                                  Miscellaneous

            SECTION 7.01. Amendment. This Agreement may be amended by the
Servicer and the Eligible Lender Trustee, with the prior written consent of the
Indenture Trustee, but without the consent of any of the Noteholders, to cure
any ambiguity, to correct or supplement any provisions in this Agreement or for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions in this Agreement or of modifying in any manner the rights
of the Noteholders; provided, however, that such action shall not, as evidenced
by an Opinion of Counsel delivered to the Eligible Lender Trustee and the
Indenture Trustee, adversely affect in any material respect the interests of any
Noteholder.

            This Agreement may also be amended from time to time by the Servicer
and the Eligible Lender Trustee, with the prior written consent of the Indenture
Trustee, the Noteholders of Notes evidencing not less than a majority of the
Outstanding Amount of the Notes and any Swap Counterparties, for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement 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 timing of,
collections of payments with respect to Financed Student 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; provided further, that the prior written
consent of any Swap Counterparties shall not be required if an Opinion of
Counsel is delivered to any Swap Counterparties stating that the proposed
amendment to this Agreement will not adversely affect in any material respect
the interests of the Noteholders or any Swap Counterparties.

            Promptly after the execution of any such amendment or consent (or,
in the case of the Rating Agencies, five Business Days prior thereto), the
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 this Agreement, the
Eligible Lender Trustee, the Indenture Trustee and any Swap Counterparties shall
be entitled to receive and rely upon an Opinion of Counsel stating that the
execution of such amendment is authorized or permitted by this Agreement and the
Opinion of Counsel referred to in Section 6.02(f) of the Loan Sale Agreement.
The Eligible Lender Trustee and the Indenture Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Eligible Lender
Trustee's or the

                                      -18-
<PAGE>

Indenture Trustee's, as applicable, own rights, duties or immunities under this
Agreement or otherwise.

            SECTION 7.02. Protection of Interests in Trust. (a) The Servicer
shall not change its name, identity or corporate structure in any manner that
would, could or might make any financing statement or continuation statement
filed in accordance with Section 6.02(a) of the Loan Sale Agreement seriously
misleading within the meaning of ss. 9-402(7) of the UCC, unless it shall have
given the Eligible Lender Trustee, the Indenture Trustee, any Swap
Counterparties and the Rating Agencies at least five days' prior written notice
thereof and shall have promptly filed appropriate amendments to all previously
filed financing statements or continuation statements.

            (b) The Servicer shall have an obligation to give the Eligible
Lender Trustee, the Indenture Trustee and any Swap Counterparties at least sixty
(60) days' prior written notice of any relocation of its principal executive
office if, as a result of such relocation, the applicable provisions of the UCC
would require the filing of any amendment of any previously filed financing or
continuation statement or of any new financing statement and shall promptly file
any such amendment. The Servicer shall at all times maintain each office from
which it shall service Financed Student Loans, and its principal executive
office, within the United States of America.

            (c) The Servicer shall maintain accounts and records of each Student
Loan accurately and in sufficient detail to permit (i) the reader thereof to
know at any time the status of such Financed Student Loan, including payments
and recoveries made and payments owing (and the nature of each) and (ii)
reconciliation between payments or recoveries on (or with respect to) each
Financed Student Loan and the amounts from time to time deposited in the
Collection Account in respect of such Financed Student Loan.

            (d) The Servicer shall, by use of a distinct identification code,
maintain its computer systems so that, from and after the time of sale under
this Agreement of the Financed Student Loans, the Servicer's master computer
records (including any backup archives) that refer to a Student Loan shall
indicate clearly the interest of the Issuer, the Eligible Lender Trustee and the
Indenture Trustee in such Student Loan and that such Student Loan is owned by
the Eligible Lender Trustee on behalf of the Issuer and has been pledged to the
Indenture Trustee. Indication of the Issuer's, the Eligible Lender Trustee's and
the Indenture Trustee's interest in a Student Loan shall be deleted from or
modified on the Servicer's computer systems when, and only when, the related
Financed Student Loan shall have been paid in full or repurchased.

            (e) If at any time the Servicer shall propose to sell, grant a
security interest in, or otherwise transfer any interest in student loans to any
prospective purchaser, lender or other transferee, the Servicer shall give to
such prospective purchaser, lender or other transferee computer tapes, records
or printouts (including any restored from backup archives) that, if they shall
refer in any manner whatsoever to any Financed Student Loan, shall indicate
clearly that such Financed Student Loan has been sold and is owned by the
Eligible Lender Trustee on behalf of the Issuer and has been pledged to the
Indenture Trustee.

                                      -19-
<PAGE>

            (f) The Servicer shall permit the Indenture Trustee and any Swap
Counterparties and their respective agents at any time during normal business
hours to inspect, audit and make copies of and abstracts from the Servicer's
records regarding any Financed Student Loan; provided, however, that the
Servicer is given reasonable prior notice of at least three (3) Business Days.

            (g) Upon request, at any time the Eligible Lender Trustee or the
Indenture Trustee shall have reasonable grounds to believe that such request
would be necessary in connection with its performance of its duties under the
Basic Documents, the Servicer shall furnish to the Eligible Lender Trustee or
the Indenture Trustee (in each case, with a copy to the Administrator), within
five (5) Business Days, a list of all Financed Student Loans (by borrower social
security number, type of loan and date of issuance) then held as part of the
Trust, and shall cause the Administrator to furnish to the Eligible Lender
Trustee or to the Indenture Trustee, within 20 Business Days thereafter, a
comparison of such list to the list of Initial Financed Student Loans set forth
in Schedule A to the Loan Sale Agreement as of the Closing Date, and, for each
Financed Student Loan that has been added to or removed from the pool of loans
held by the Eligible Lender Trustee on behalf of the Issuer, information as to
the date as of which and circumstances under which each such Financed Student
Loan was so added or removed.

            SECTION 7.03. Notices. Unless otherwise agreed by the recipient, all
demands, notices and communications upon or to the Seller, Bank One, the
Servicer, the Eligible Lender Trustee, the Indenture Trustee, the Administrator,
the Rating Agencies or any Swap Counterparties under this Agreement shall be in
writing, personally delivered or mailed by certified mail, return receipt
requested (or in the form of telex or facsimile notice, followed by written
notice delivered as aforesaid or postage prepaid, first class mail), and shall
be deemed to have been duly given upon receipt;

contained herein, except as provided in the succeeding sentence, as provided in
