                               -------------------

         2.1. TERI hereby guarantees to Eligible Lender Trustee on behalf of the

of the principal (including capitalized interest) of and accrued interest on
every Financed Private Loan which is a TERI Guaranteed Loan with respect to

name of the Eligible Borrower, setting forth the Guarantee Event that has
occurred, and including all documents required under Section 2.2. All payments
made by TERI hereunder shall be directed to the applicable Servicer on behalf of
the Eligible Lender Trust.

         2.2 TERI's above guarantee with respect to any given Financed Private
Loan that is a TERI Guaranteed Loan is conditioned upon the following:

                  (a)      The claim must have been filed within the time

                           provided, however, that no claim for guarantee shall
                           be denied by TERI solely because the Financed Private
                           Loan, when added to the other educational Loans for
                           that Eligible Borrower, exceeds the maximum aggregate
                           limits set forth in the applicable Coordination

                           all material respects in accordance with the terms
                           and provisions of the applicable Servicing
                           Agreements.

                  (d)      TERI must have received the private guarantee fees, 
                           or TERI's share thereof, applicable to the Financed
                           Private Loan in accordance with the applicable
                           Deposit Agreement.

                  (e)      TERI must have received the original of the
                           Promissory Note for the Financed Private Loan (or, in
                           the event the original has been lost, misplaced or
                           destroyed, a copy with accompanying affidavit
                           describing with particularity said loss, misplacement
                           or destruction), endorsed to TERI in such manner as
                           to transfer to TERI all rights in and title to such
                           Promissory Note, free and


                                      -4-

                           clear of all liens and encumbrances, and except as
                           set forth in Section 2.4 of this Guarantee Agreement
                           and as permitted by any provision of the applicable
                           Coordination Agreement, of all defenses,
                           counterclaims, offsets, and rights of rescission that
                           might be raised by the Eligible Borrower. Acceptance
                           of a claim by TERI shall not constitute a waiver by
                           TERI of any defenses TERI might have to such claim.

         2.3. TERI's guarantee obligation with respect to any Financed Private
Loan that is a TERI Guaranteed Loan shall not be terminated or otherwise
affected or impaired (i) by Eligible Lender Trustee's or a Servicer's granting
any extension to any Eligible Borrower of time to make the scheduled payments,
or by any other indulgence or indulgences Eligible Lender Trustee or a Servicer
may grant to any Eligible Borrower, provided that all extensions and other
indulgences substantially meet the forbearance standards and other requirements
of the applicable Servicing Agreements, (ii) because of any fraud, illegal or
improper acts of any Eligible Borrower, or (iii) except as provided in Section
2.4, because any Eligible Borrower may, by operation of law or otherwise, be
relieved of liability upon his or her Financed Private Loans.

         2.4. Notwithstanding anything herein to the contrary, in the event that
any Financed Private Loan that is a TERI Guaranteed Loan becomes unenforceable
because the terms thereof, or the forms of the application or Promissory Note
related thereto, violate any provision of applicable state law, TERI shall be
obligated to pay Eligible Lender Trustee one-half (1/2) of the unpaid principal
balance (including capitalized interest) thereof and accrued interest thereon to
the date of payment, and if the unenforceability of the Financed Private Loan is
discovered after payment of the guarantee claim has been made in accordance with
Section 2.1, Seller shall forthwith reimburse TERI for one-half (1/2) of TERI's
guarantee payment.

         2.5. If TERI denies a claim on any Financed Private Loan that is a TERI
Guaranteed Loan on the grounds that it fails to meet the conditions contained
within Section 2.2, Eligible Lender Trustee or a Servicer on Eligible Lender
Trustee's behalf may thereafter request that TERI reinstate the guarantee of
such Financed Private Loan which request will not be unreasonably denied;
provided, however, (i) Eligible Lender Trustee or such Servicer corrects the
deficiencies and receives three consecutive full monthly payments from the
Eligible Borrower and (ii) at the time of Eligible Lender Trustee's or such
Servicer's request that the Eligible Borrower is within thirty (30) days of
being current on his or her payments on such Financed Private Loan.

         2.6. TERI's guarantee hereunder is continuing and an absolute guarantee
of payment covering the Financed Private Loans that are TERI Guaranteed Loans
now or hereafter owned by Eligible Lender Trustee on behalf of the Trust.

         2.7. With respect to any Financed Private Loan that is a TERI
Guaranteed Loan, if TERI fails to honor its guarantee commitment under this
Guarantee Agreement, its guarantee obligation to Eligible Lender Trustee shall
be effective immediately, without demand, presentment, protest or notice of any
kind, all of which are hereby waived.

         2.8. TERI agrees not to exercise any right of subrogation,
reimbursement, indemnity, contribution or the like against any Eligible Borrower
unless and until all of TERI's obligations to Eligible Lender Trustee under this
Guarantee Agreement with respect to such Eligible Borrower's Loans have been
satisfied in full.

                                   SECTION 3.

                              OBLIGATIONS OF TERI.
                              --------------------

         3.1. (a) TERI shall furnish to Administrator (i) within forty-five (45)

balance sheet at the end of such period and a profit and loss statement for that

Debt Collection Practices Act, applicable retail installment acts, and state
collection statutes.

         3.3 TERI agrees that so long as this Guarantee Agreement remains in
effect:

                  (a)      it will not cause or permit its Operating Reserve to
                           fall below 3% of TERI Guaranteed Loans, provided,
                           that if TERI shall obtain reinsurance while this
                           Guarantee Agreement remains in effect, TERI may
                           adjust its Operating Reserve percentage to the same
                           extent that any such adjustment is made to the
                           required level of TERI's Operating Reserves under the
                           substantially similar provisions of other guarantee
                           agreements to which Seller and TERI are parties if
                           the reinsurance obtained applies to the Financed
                           Private Loans that are TERI Guaranteed Loans and TERI
                           observes and complies with respect to such Financed
                           Private Loans with the same terms, conditions or
                           covenants applicable to the adjustment of Operating
                           Reserves under such other guarantee agreements; and

                  (b)      at least semi-annually, TERI, at its sole cost and
                           expense, will submit to the Eligible Lender Trustee

                           accounting or actuarial firm in accordance with the

                                      -6-
   7



                           American Academy of Actuaries and the then current
                           Actuarial Standards of Practice adopted by the
                           Actuarial Standards Board, which, by its terms, may
                           be relied upon by Seller and the Eligible Lender
                           Trustee and which establishes that TERI's existing
                           loan loss reserves for each loan program are adequate
                           to cover anticipated estimated future net defaults.

                           In the event that its Operating Reserve falls below
                           the level required by (a) above or the Actuarial
                           Report fails to establish the adequacy of loan loss
                           reserves, as described in (b) above, and TERI fails,
                           within 30 days of its receipt of notice of such
                           situation, to provide the Eligible Lender Trustee
                           with evidence that such situation has been corrected,
                           then TERI shall not guarantee any additional loans
                           for any lender and shall not undertake any additional
                           commitments to guarantee any such loans without the
                           express written consent of the Eligible Lender
                           Trustee, which consent shall not be unreasonably
                           withheld; provided, that nothing in this section
                           shall prohibit TERI from continuing to guarantee
                           loans for a lender which has a binding commitment to
                           lend to a borrower; and further provided that nothing
                           in this section shall prohibit TERI from continuing
                           to guarantee loans originated by Seller under the
                           Program or otherwise.

         3.4. TERI agrees that it will not (i) undertake any additional
commitments to guarantee any loans, (ii) undertake any additional business
opportunities, or (iii) make any gifts or expend any funds, if in its reasonable
belief, such additional commitments, guarantees, business opportunities, gifts
or expenditures would cause its Operating Reserve to at any time fall below the
level required by Section 3.3 of this Guarantee Agreement.

                                   SECTION 4.

               OBLIGATIONS OF SELLER AND ELIGIBLE LENDER TRUSTEE.
               --------------------------------------------------

         4.1. If TERI shall have purchased a Financed Private Loan that is a

purchase such Financed Private Loan from TERI if TERI succeeds, after purchase,
in obtaining from the affected Eligible Borrower three (3) full consecutive
monthly payments. Seller shall have no obligation to purchase any such Financed
Private Loan unless and until (i) the aggregate principal balance (including
capitalized interest) on Private Loans (which, for purposes of this Section 4.1,
include Financed Private Loans and any other Private Loan which Seller is
obligated to repurchase pursuant to the substantially similar provisions of any
guarantee agreement to which TERI and Seller are parties) to be purchased equals

hereunder; (ii) all such Financed Private Loans subject to purchase are less
than thirty (30) days past due at time of such notice, and (iii) TERI provides

forty-five (45) days of receipt of written notice from TERI. This purchase
obligation may be invoked by TERI only once as to any Financed Private Loan. In
addition to the foregoing, if TERI shall have purchased a Financed Private Loan
that is a TERI Guaranteed Loan for which a copy of the Promissory Note was not
received as provided in Section 2.2(e), Seller shall purchase such Financed
Private Loan within forty-five (45)

days of written notice from TERI that the Promissory Note was held unenforceable
by a court of competent jurisdiction as the result of the unavailability of the
original of such Promissory Note. TERI agrees to endorse the original of such
Promissory Note (or, in the event the original has been lost, misplaced, or
destroyed, a copy with accompanying affidavit describing with particularity said
loss, misplacement or destruction) purchased by Seller in accordance with the
provisions of this paragraph in such manner as to transfer to Seller all rights
in and title to such Promissory Note, free and clear of all claims, liens,
encumbrances, defenses, counterclaims, offsets, and rights of rescission that
might be raised by an Eligible Borrower as a result of any action or inaction by
TERI in the servicing and collection of such Financed Private Loan during the
time such Financed Private Loan was owned by TERI.

         4.2. Eligible Lender Trustee agrees to fully cooperate with TERI in the
prosecution of any claim in bankruptcy court to determine the dischargeability
of any Financed Private Loan that is a TERI Guaranteed Loan of an Eligible
Borrower. Notwithstanding the foregoing, TERI shall be responsible for any and
all attorneys' fees and court costs and any costs and expenses of the Eligible
Lender Trustee in connection with the prosecution of any claim to determine
dischargeability.

                                   SECTION 5.

                         REPRESENTATIONS AND WARRANTIES.
                         -------------------------------

         5.1. Each party with respect to itself represents and warrants that the
making and performance of this Guarantee Agreement and the activities
contemplated under this Guarantee Agreement have been duly authorized by all
necessary corporate action, and do not and will not:

                  (a)      violate any provision of applicable law, or any
                           applicable regulation, order, decree, writ or
                           injunction, or any provision of its charter or
                           bylaws; or

                  (b)      violate or result in the breach of, or constitute a
                           default or require any consent under, any material
                           agreement or material instrument by which it or any
                           of its property may be bound or affected;

and this Guarantee Agreement is the legal, valid and binding obligation of such
party, enforceable in accordance with the terms of this Guarantee Agreement
subject to (i) the exercise of judicial discretion in accordance with general
principles of equity, (ii) the exercise of the police powers of the several
states of the United States of America, (iii) the constitutional powers of the
United States of America, and (iv) the bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting creditor's rights generally. Each party
with respect to itself further represents and warrants that there is no pending
or threatened litigation that would materially impact that party's ability to
perform its obligations under this Guarantee Agreement.

                                   SECTION 6.

                                 MISCELLANEOUS.
                                 --------------

         6.1. The obligations under this Guarantee Agreement of each of the
parties are several and distinct, each party being responsible solely for its
own performance pursuant to the terms and conditions contained in this Guarantee
Agreement. Each party agrees to pay for any loss, liability or expense,
including reasonable attorneys' fees resulting from, or attributable to, any
breach by that party of its obligations arising under this Guarantee Agreement
where the final determination of liability on the part of such party is
established by an arbitrator (to which such party has agreed to submit), by a
court of law with appropriate jurisdiction or by way of settlement agreed to by
such party. This shall not be construed to limit any party's rights,
obligations, liabilities, claims or defenses which arise as a matter of law or
pursuant to any other provision of this Guarantee Agreement.

         6.2. None of the parties hereto is or will hold itself out to be the
agent of any of the other parties with regard to any transaction under or
pursuant to this Guarantee Agreement except as otherwise described with respect
to the Seller, the Eligible Lender Trustee or the Administrator in the Sale and
Servicing Agreement or the Administration Agreement.

         6.3. Each party's respective rights, remedies, powers, privileges, and
discretion ("Rights and Remedies") shall be cumulative and not exclusive of any
rights. No delays or omissions by any party in exercising or enforcing any of
its Rights and Remedies shall operate as or constitute a waiver of them. No
waiver by a party of any default under this Guarantee Agreement shall operate as
a waiver of any other default under this Guarantee Agreement. No single or
partial exercise by a party of any of its Rights and Remedies shall preclude the
other or further exercise of such Rights and Remedies. No waiver or modification
of a party's Rights and Remedies on any one occasion shall be deemed a waiver on
any subsequent occasion, nor shall it be deemed a continuing waiver. All Rights
and Remedies shall be cumulative and not alternative or exclusive, and a party
may exercise them at such time or times and in such order of preference as it in
its sole discretion may determine.

         6.4. This Guarantee Agreement may be modified only by written agreement
of the parties to this Guarantee Agreement, except as may otherwise be set forth
in this Guarantee Agreement.

         6.5. Any determination that any provision of this Guarantee Agreement
is invalid, illegal, or unenforceable in any respect shall not affect the
validity, legality, or enforceability of such provision in any other instance
and shall not affect the validity, legality, or enforceability of any other
provision of this Guarantee Agreement.

         6.6. This Guarantee Agreement shall be governed and construed in
accordance with Massachusetts law, without regard to principles of conflict of
laws. Eligible Lender Trustee, Seller and TERI each consent to jurisdiction in
the Court of Common Pleas for Cuyahoga County, Ohio, the United States District
Court for the Northern District of Ohio, Eastern Division, the appropriate Court
Department for Suffolk County, located in Boston, Massachusetts, and the United
States District Court for the District of Massachusetts, as judicial forums
within which any action to enforce the provisions hereof or any disputes arising
under this Guarantee Agreement may be brought.

         6.7. This Guarantee Agreement may not be assigned or delegated by TERI
or Seller without Eligible Lender Trustee's written consent. The rights of
Eligible Lender Trustee hereunder may be assigned in whole or in part by
Eligible Lender Trustee to any permitted successor or to any purchaser of all or
any part of its interest in the Financed Private Loans without TERI's approval;
provided, however, that Eligible Lender Trustee's obligations hereunder shall be
assumed by any such successor or purchaser in writing. TERI acknowledges that
Eligible Lender Trustee will pledge the Financed Private Loans and all its
rights hereunder to Indenture Trustee and agrees that in the event Indenture
Trustee forecloses upon such collateral, Indenture Trustee may exercise any or
all of Eligible Lender Trustee's rights hereunder.

         6.8. All notices under this Guarantee Agreement shall be sent by any
means requiring receipt signature, or if by facsimile confirmed by first class
mail, postage or other delivery charge prepaid to:

Agreement.

instrument has been signed by The First National Bank of Chicago not in its
individual capacity but solely in its capacity as Eligible Lender Trustee of the
Trust and in no event shall The First National Bank of Chicago in its individual
capacity have any liability for the representations, warranties, covenants,
agreements or other obligations of Eligible Lender Trustee of the Trust
