retained at all times by the related AMS Trustee pursuant to the related AMS
Trust Agreement, together with a pledge of a security interest in such Federal

title to the Purchased Federal Student Loans described in the preceding sentence

                  Section 6. Security Interest. (a) Buyer and the Seller intend
that the Transactions hereunder be sales to Buyer of Seller's beneficial right,
title and interest in and to the Purchased Student Loans (legal title shall
remain with the related AMS Trust) and not loans from Buyer to Seller secured by
the Purchased Student Loans. However, in order to preserve Buyer's rights under
this Agreement, in the event that a court or other forum recharacterizes the
Transactions hereunder as loans and as security for the performance by Seller of
all of Seller's obligations to Buyer under this Agreement and the Transactions
entered into pursuant to this Agreement, Seller grants (which grant is made with
respect to the Purchased Federal Student Loans to the related Eligible Lender
Trustee for the benefit of Buyer) a first priority security interest in the
Seller's beneficial interest in Purchased Student Loans, any proceeds thereof,
the Collection Account, to the Servicing Agreements to the extent they pertain
to the Purchased Student Loans, all rights with respect to the related Guarantee
Agreements, and all servicing records pertaining to Purchased Student Loans,
owned by Seller, including but not limited to any and all files, documents,
records, data bases, computer tapes, copies of computer tapes, closing
documentation, payment history records, and any other records relating to or
evidencing the servicing of Purchased Student Loans (the "Servicing Records"),
the LCPI Purchased Student Loans and which grant includes as to Federal Student
Loans, the grant by the related AMS Trustee, which the related AMS Trustee
hereby makes at the instruction of the Seller, to the

                                      -9-
<PAGE>

related Eligible Lender Trustee of a first priority security interest in legal
title to the Federal Student Loans and all other rights to the Purchased Federal
Student Loans held by the related AMS Trust, and in each case all proceeds
thereof.

                  (b) Seller shall pay all fees and expenses associated with
perfecting Buyer's security interest in the Purchased Student Loans, including,
without limitation, the cost of filing financing documents under the UCC, as and
when required by Buyer in its sole discretion.

                  Section 7. Payment, Transfer and Custody. (a) Unless otherwise
mutually agreed in writing, all transfers of funds hereunder shall be in
immediately available funds.

                  (b) On the Purchase Date for each Transaction, ownership of
the Purchased Student Loans shall be transferred to the Buyer or its designee
(subject in the case of Purchased Federal Student Loans, to the retention of
legal title thereto by an AMS Trustee in its capacity as "eligible lender' under
the Higher Education Act as in Section 1 set forth,) against the simultaneous
transfer of the Purchase Price to an account of Seller specified in the
Confirmation.

                  (c) Seller shall use its best efforts to make arrangements as
soon as possible, but in no event later than August 31, 2003 for the Buyer to
wire or ACH transfer the Purchase Price with respect to the Student Loans
directly to the related Servicers (the "Direct Wiring Capability").

                  (d) Seller hereby agrees that, with respect to Student Loans
which are originated simultaneously with their funding hereunder, the Purchase
Price shall be delivered as follows:

                  (i) Prior to Seller's arranging for the Direct Wiring
         Capability, on the Purchase Date for each Transaction, the Buyer shall
         wire the Purchase Price to the Seller.

                  (ii) (A) Upon Seller's arranging for the Direct Wiring
         Capability, on or prior to the Purchase Date for each Transaction, the
         Seller shall (1) deliver to the Buyer wiring instructions and amounts
         with respect to the Purchased Student Loans to be funded on such
         Purchase Date and (2) remit to the Buyer's designated account an amount
         equal to 4% of the principal balance of the Purchased Student Loans to
         be funded on such Purchase Date.

                       (B) Funds shall be wired directly to the applicable
         Servicer or such funds shall be made available to the applicable
         Servicer for ACH transfer. Prior to the Buyer purchasing any Student
         Loans serviced by a Servicer, such Direct Wire Servicer shall have
         executed a letter agreement, in a form acceptable to the Buyer,
         pursuant to which the Servicer agrees, among other things, to hold such
         funds as Buyer's disbursement agent. Buyer shall retain 3% of the
         principal balance of the Purchased Student Loans to be funded on such
         Purchase Date for payment of required fees with respect to the
         Purchased Student Loan on a quarterly basis.

                  (e) Seller, simultaneously with the delivery to Buyer or its
designee of the Purchased Student Loans relating to each Transaction hereby
sells, transfers, conveys and assigns to Buyer or its designee without recourse,
but subject to the terms of this Agreement, all

                                      -10-
<PAGE>

the right, title and interest of Seller in and to the Purchased Student Loans,
including all right, title and interest in and to the Guaranty agreements with
respect thereto, all Subsidy Payments and all federal guaranty or reinsurance
payments with respect thereto and all proceeds of each of the foregoing.

                  (f) Any Loan Files are and shall be held in trust by Seller's
designated servicer as bailee or custodian of the related Eligible Lender
Trustee for the benefit of Buyer as the beneficial owner thereof as specifically
designated in the Repurchase Trust Agreement or related AMS Trust Agreement, as
applicable. The books and records (including, without limitation, any computer
records or tapes) of Seller and the related Eligible Lender Trustee pertaining
to the Purchased Student Loans shall be marked appropriately to reflect clearly
the sale of the related Purchased Student Loan to Buyer.

                  Section 8. Rehypothecation or Pledge of Purchased Student
Loans. Title to all Purchased Student Loans shall pass to Buyer (except that,
with respect to the Purchased Federal Student Loans, title shall be held of
record by the related AMS Trustee as set forth in Section 1). Buyer shall have
free and unrestricted use of all Purchased Student Loans, subject to the
requirement, in the case of Purchased Federal Student Loans, that legal title
thereto shall at all times remain held by an "eligible lender" as defined in the
Higher Education Act. Nothing in this Agreement shall preclude Buyer from
engaging in repurchase transactions with the Purchased Student Loans or
interests therein or otherwise pledging, repledging, hypothecating, or
rehypothecating the Purchased Student Loans or interests therein, but no such
transaction shall relieve Buyer of its obligations to transfer Purchased Student
Loans to Seller pursuant to Section 3. Nothing contained in this Agreement shall
obligate Buyer to segregate any Purchased Student Loans delivered to Buyer by
Seller. In the event that there is a material adverse change or other
development in the repurchase markets which results in Buyer being unable to
finance its position through the repurchase market with its traditional
repurchase counterparties, Buyer may accelerate the Repurchase Date for any
outstanding Transactions following reasonable written notice to Seller of the
occurrence of such event. In addition, in the event that any payment of the
Repurchase Price occurs prior to the Repurchase Date set forth in the applicable
Confirmation, Seller shall pay upon demand any resulting loss, cost or expense
incurred by the Buyer, including, but not limited to, any loss (including loss
of anticipated profits), cost or expense incurred in liquidating or employing
deposits from third parties or other financing arrangements with respect to its
position in the Purchased Student Loans.

                  Section 9. Substitution. (a) Subject to Section 9(b), Seller
may, upon two (2) Business Days' written notice to Buyer, substitute other
Student Loans for any Purchased Student Loans. Such substitution shall be made
by transfer to Buyer or its designee (such transfer to be reflected on Schedule
I hereto) of the Loan File of such other Student Loans and transfer to Seller or
its designee of the Purchased Student Loans requested for release. After
substitution, the substituted Student Loans shall be deemed to be Purchased
Student Loans subject to the same Transaction as the released Student Loans.

                  (b) Notwithstanding anything to the contrary in this
Agreement, Seller may not substitute other Student Loans for any Purchased
Student Loans (i) if after taking into account such substitution, a Collateral
Deficit would occur on (ii) such substitution would cause a breach of any
provision of this Agreement.

         available, as applicable, to Seller's or Guarantor's counterparty with

         long term credit rating investment grade or (y) no TERI Loans are
         included in the Purchased Student Loans); or

                  (xiv) An Event of Default with respect to Seller or guarantor
         shall occur under the Subordination and Intercreditor Agreement.

                  (b) In making a determination as to whether an Event of
Default has occurred, the Buyer shall be entitled to rely on reports published
or broadcast by media sources believed by such party to be generally reliable
and on information provided to it by any other sources believed by it to be
generally reliable, provided that such party reasonably and in good faith
believes such information to be accurate and has taken such steps as may be
reasonable in the circumstances to attempt to verify such information.

                  Section 14. Remedies. (a) If an Event of Default occurs with
respect to Seller, the following rights and remedies are available to Buyer:

                  (i) At the option of Buyer, exercised by written notice to
         Seller (which option shall be deemed to have been exercised, even if no
         notice is given, immediately upon the occurrence of an Act of
         Insolvency), the Repurchase Date for each Transaction hereunder shall
         be deemed immediately to occur.

                  (ii) If Buyer exercises or is deemed to have exercised the
         option referred to in subsection (a)(i) of this Section,

                           (A) Seller's obligations hereunder to repurchase all
                  Purchased Student Loans in such Transactions shall thereupon
                  become immediately due and payable,

                                      -17-
<PAGE>

                           (B) to the extent permitted by applicable law, the
                  Repurchase Price with respect to each such Transaction shall
                  be increased by the aggregate amount obtained by daily
                  application of, on a 360 day per year basis for the actual
                  number of days during the period from and including the date
                  of the exercise or deemed exercise of such option to but
                  excluding the date of payment of the Repurchase Price as so
                  increased, (x) the greater of the Prime Rate or the Pricing
                  Rate for each such Transaction to (y) the Repurchase Price for
                  such Transaction as of the Repurchase Date as determined
                  pursuant to subsection (a)(i) of this Section (decreased as of
                  any day by (I) any amounts actually in the possession of Buyer
                  pursuant to clause (C) of this subsection, (II) any proceeds
                  from the sale of Purchased Student Loans applied to the
                  Repurchase Price pursuant to subsection (a)(xiii) of this
                  Section, and (III) any amounts applied to the Repurchase Price
                  pursuant to subsection (a)(iii) of this Section), and

                           (C) all Income on the Purchased Student Loans
                  actually received in the Collection Account pursuant to
                  Section 5 shall be applied to the aggregate unpaid Repurchase
                  Price owed by Seller.

                  (iii) After one Business Day's notice to Seller (which notice
         need not be given if an Act of Insolvency with respect to Seller or
         Guarantor shall have occurred, and which may be the notice given under
         subsection (a)(i) of this Section), Buyer, to the extent permitted by
         the Higher Education Act, may instruct the related Eligible Lender
         Trustee to (A) immediately sell, without notice or demand of any kind,
         at a public or private sale and at such price or prices Buyer may
         reasonably deem satisfactory any or all Purchased Student Loans subject
         to a Transaction hereunder (including with respect to any Federal
         Student Loans legal title thereto, and all rights therein held by the
         related AMS Trustee, in accordance with the Higher Education Act) or
         (B) in its sole discretion elect, in lieu of selling all or a portion
         of such Purchased Student Loans, to give Seller credit for such
         Purchased Student Loans in an amount equal to the Market Value of the
         Purchased Student Loans against the aggregate unpaid Repurchase Price
         and any other amounts owing by Seller hereunder. The proceeds of any
         disposition of Purchased Student Loans shall be applied first to the
         costs and expenses incurred by Buyer in connection with the Event of
         Default; second to consequential damages, including but not limited to
         costs of cover and/or related hedging transactions; third to the
         Repurchase Price; and fourth to any other outstanding obligation of
         Seller or Guarantor or any Affiliate thereof to Buyer hereunder or
         under any other agreement between Buyer and such parties or otherwise.

                  (iv) The parties recognize that it may not be possible to
         purchase or sell all of the Purchased Student Loans on a particular
         business Day, or in a transaction with the same purchaser, or in the
         same manner because the market for such Purchased Student Loans may not
         be liquid. In view of the nature of the Purchased Student Loans, the
         parties agree that liquidation of a Transaction or the underlying
         Purchased Student Loans does not require a public purchase or sale and
         that a good faith private purchase or sale shall be deemed to have been
         made in a commercially reasonable manner. Accordingly, Buyer may elect,
         in its sole discretion, the time and manner of liquidating any
         Purchased Student Loan and nothing contained herein shall (A) obligate
         Buyer to liquidate any Purchased Student Loan on the occurrence of an
         Event of Default or to liquidate all

                                      -18-
<PAGE>

         Purchased Student Loans in the same manner or on the same Business Day
         or (B) constitute a waiver of any right or remedy of Buyer. However, in
         recognition of the parties' agreement that the Transactions hereunder
         have been entered into in consideration of and in reliance upon the
         fact that all Transactions hereunder constitute a single business and
         contractual relationship and that each Transaction has been entered
         into in consideration of the other Transactions, the parties further
         agree that Buyer shall use its best efforts to liquidate all
         Transactions hereunder upon the occurrence of an Event of Default as
         quickly as is prudently possible in the reasonable judgment of Buyer.

                  (v) Buyer shall, without regard to the adequacy of the
         security for the Seller's obligations under this Agreement, be entitled
         to the appointment of a receiver by any court having jurisdiction,
         without notice, to (or cause the Eligible Lender Trustee to) take
         possession of and protect, collect, manage, liquidate, and sell the
         Purchased Student Loans or any portion thereof, and collect the
         payments due with respect to the Purchased Student Loans or any portion
         thereof. Seller shall pay all costs and expenses incurred by Buyer in
         connection with the appointment and activities of such receiver.

                  (vi) Seller agrees that Buyer may obtain an injunction or an
         order of specific performance to compel Seller to fulfill its
         obligations as set forth in Section 25, if Seller fails or refuses to
         perform its obligations as set forth therein.

                  (vii) Seller shall be liable to Buyer for the amount of all
         expenses, reasonably incurred by Buyer in connection with or as a
         consequence of an Event of Default, including, without limitation,
         reasonably legal fees and expenses and reasonable costs incurred in
         connection with hedging or covering transactions, and Seller shall be
         liable for all fees and charges of the related Eligible Lender Trustee
         and the Servicers whether incurred before or after an Event of Default.

                  (viii) Buyer shall have all the rights and remedies provided
         herein, provided by applicable federal, state, foreign, and local laws
         (including, without limitation, the rights and remedies of a secured
         party under the applicable UCC to the extent that such UCC is
         applicable, and the right to offset any mutual debt and claim), in
         equity, and under any other agreement between Buyer and Seller or
         Guarantor.

                  (ix) Buyer may exercise one or more of the remedies available
         to Buyer immediately upon the occurrence of an Event of Default and,
         except to the extent provided in subsection (a)(iii) of this Section,
         at any time thereafter without notice to Seller or Guarantor. All
         rights and remedies arising under this Agreement as amended from time
         to time hereunder are cumulative and not exclusive of any other rights
         or remedies which Buyer may have.

                  (x) In addition to its rights hereunder, Buyer shall have the
         right to proceed against any assets of Seller which may be in the
         possession of Buyer or its designee including the right to liquidate
         such assets and to set off the proceeds against monies owed by Seller
         to Buyer pursuant to this Agreement. Buyer may set off cash, the
         proceeds of the liquidation of the Purchased Student Loans, and all
         other sums or obligations owed by Seller to Buyer against all of
         Seller's obligations to Buyer, whether

                                      -19-
<PAGE>

         under this Agreement, under a Transaction, or under any other agreement
         between the parties, whether or not such obligations are then due,
         without prejudice to Buyer's right to recover any deficiency. Any cash,
         proceeds, or property in excess of any amounts due, or which Buyer
         reasonably believes may become due, to it from Seller shall be returned
         to Seller after satisfaction of all obligations of Seller to Buyer.

                  (xi) Buyer may enforce its rights and remedies hereunder
         without prior judicial process or hearing, and Seller hereby expressly
         waives any defenses Seller might otherwise have to require Buyer to
         enforce its rights by judicial process. Seller also waives any defense
         Seller might otherwise have arising from the use of nonjudicial
         process, enforcement and sale of all or any portion of the Purchased
         Student Loans in a commercially reasonable manner as set forth in this
         Agreement, or from any other election of remedies. Seller recognizes
         that nonjudicial remedies are consistent with the usages of the trade,
         are responsive to commercial necessity and are the result of a bargain
         at arm's length.

                  (xii) Buyer and Seller hereby agree that sales of the
         Purchased Student Loans shall be deemed to include and permit the sales
         of Purchased Student Loans pursuant to a securities offering.

                  (xiii) Notwithstanding the foregoing remedies, if the Event of
         Default (other than an Event of Default under Section 13(a)(x)) arises
         from a breach of any representation or warranty set forth in Exhibit
         III attached hereto or the breach of the covenants contained in Section
         12(i) with respect to a Purchased Student Loan, then Seller may elect,
         subject to Buyers' written consent (which consent shall not be
         unreasonably withheld or delayed), to cure such default by repurchasing
         such Student Loan or substituting for such Student Loan within two (2)
         Business Days of such Event of Default, provided, however, that Seller
         shall not have the right to make the foregoing election if such breach
         causes a default with respect to Student Loans that in the aggregate
         represent ten percent (10%) or more of the aggregate Purchase Price of
         all Purchased Student Loans subject to then outstanding Transactions.
         The repurchase price for any such repurchase shall be the outstanding
         Repurchase Price allocable to such Student Loan. Any such substitution
         shall be performed in accordance with Section 9 of this Agreement.

                  Section 15. Additional Conditions. Seller shall, on the date
of the initial Transaction hereunder and, upon the request of Buyer, on the date
of any subsequent Transaction, cause to be delivered to Buyer, with reliance
thereon permitted as to any Person that purchases the Purchased Student Loans
from Buyer in a repurchase transaction, a favorable opinion or opinions of
counsel with respect to the matters set forth in Exhibit II attached hereto
relating to the Transactions described herein. In addition, Buyer shall have
received the structuring fee and any evidence of corporate authority of Seller
as reasonably requested.

                  Section 16. Single Agreement. Buyer and Seller acknowledge
that, and have entered hereunto and will enter into each Transaction hereunder
in consideration of and in reliance upon the fact that, all Transactions
hereunder constitute a single business and contractual relationship and that
each has been entered into in consideration of the other Transactions.
Accordingly, each of Buyer and Seller agrees (i) to perform all of its
obligations in respect of

                                      -20-
<PAGE>

each Transaction hereunder, and that a default in the performance of any such
obligations shall constitute a default by it in respect of all Transactions
hereunder, (ii) that each of them shall be entitled to set off claims and apply
property held by them in respect of any Transaction against obligations owing to
them in respect of any other Transactions hereunder and (iii) that payments,
deliveries and other transfers made by either of them in respect of any
Transaction shall be deemed to have been made in consideration of payments,
deliveries, and other transfers in respect of any other Transactions hereunder,
and the obligations to make any such payments, deliveries, and other transfers
may be applied against each other and netted; provided, however, that the
parties hereto acknowledge and agree that each Purchased Student Loan is
identified and unique and nothing in this Agreement should limit or reduce
Buyer's obligation to deliver the Purchased Student Loans to Seller or Seller's
obligation to sell the Purchased Student Loans to Buyer, in each case as and
when provided herein.

                  Section 17. Notices and Other Communications. Unless another
address is specified in writing by the respective party to whom any written
notice or other communication is to be given hereunder, all such notices or
communications shall be in writing or confirmed in writing and delivered at the
respective addresses set forth in the Confirmation.

                  Section 18. Entire Agreement; Severability. This Agreement
together with the applicable Confirmation, the Repurchase Trust Agreement and
the related AMS Trust Agreement constitutes the entire understanding between
Buyer and Seller with respect to the subject matter it covers and shall
supersede any existing agreements between the parties containing general terms
and conditions for repurchase transactions involving Purchased Student Loans. By
acceptance of this Agreement, Buyer and Seller acknowledge that they have not
made, and are not relying upon, any statements, representations, promises or
undertakings not contained in this Agreement, the Repurchase Trust Agreement and
the related AMS Trust Agreement (or to the extent relevant, the related AMS
Trust Agreement). Each provision and agreement herein shall be treated as
separate and independent from any other provision or agreement herein and shall
be enforceable notwithstanding the unenforceability of any such other provisions
or agreement.

                  Section 19. Non-Assignability. The rights and obligations of
the Seller under this Agreement and under any Transaction shall not be assigned
by it without the prior written consent of Buyer. Nothing herein shall restrict
Buyer's ability to participate its interests in this Agreement, to the extent
permitted by law. Subject to the foregoing, this Agreement and any Transactions
shall be binding upon and shall inure to the benefit of the parties and their
respective successors and assigns. Nothing in this Agreement express or implied,
shall give to any person, other than the parties to this Agreement and their
successors hereunder, any benefit or any legal or equitable right, power, remedy
or claim under this Agreement.

                  Section 20. Terminability. This Agreement shall terminate on
August 31, 2003 after the date of the Original Master Repurchase Agreement
unless the Buyer and Seller agree to extend this Agreement for a period of 30
days therefrom, but will remain applicable to any Transactions then outstanding
until payment of the Repurchase Price with respect thereto or any other amounts
due hereunder.

                                      -21-
<PAGE>

                  Section 21. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW
YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF.

                  Section 22. Consent to Jurisdiction and Arbitration. The
parties irrevocably agree to submit to the personal jurisdiction of the United
States District court for the Southern District of New York, the parties
irrevocably waiving any objection thereto. If, for any reason, federal
jurisdiction is not available, and only if federal jurisdiction is not
available, the parties irrevocably agree to submit to the personal jurisdiction
of the Supreme Court of the State of New York, sitting in New York County, the
parties irrevocably waiving any objection thereto. Notwithstanding the foregoing
two sentences, at either party's sole option exercisable at any time not later
than thirty (30) days after an action or proceeding has been commenced, the
parties agree that the matter may be submitted to binding arbitration in
accordance with the commercial rules of the American Arbitration Association
then in effect in the State of New York and judgment upon any award rendered by
the arbitrator may be entered in any court having jurisdiction thereof within
the City, County and State of New York; provided, however, that the arbitrator
shall not amend, supplement, or reform in any regard this Agreement or the terms
of any Confirmation, the rights or obligations of any party hereunder or
thereunder, or the enforceability of any of the terms hereof or thereof. Any
arbitration shall be conducted before a single arbitrator who shall be
reasonably familiar with repurchase transactions and the student loan industry
and secondary student loan market.

                  Section 23. No Waivers, Etc. No express or implied waiver of
any Event of Default by either party shall constitute a waiver of any other
Event of Default and no exercise of any remedy hereunder by any party shall
constitute a waiver of its right to exercise any other remedy hereunder. No
modification or waiver of any provision of this Agreement and no consent by any
party to a departure herefrom shall be effective unless and until such shall be
in writing and duly executed by both of the parties hereto. Any such waiver or
modification shall be effective only in the specific instance and for the
specific purpose for which it was given.

                  Section 24. Intent. The parties understand and intend that to
the maximum extent permitted by law, this Agreement and each Transaction
hereunder constitute a "repurchase agreement" and a "securities contract" as
those terms are defined under the relevant provisions of Title 11 of the United
States Code, as amended.

                  Section 25. Servicing. (a) Notwithstanding the purchase and
sale of the Purchased Student Loans hereby, Seller shall cause each Servicer to
service the related Purchased Student Loans for the benefit of Buyer and, if
Buyer shall exercise its rights to pledge or hypothecate the Purchased Student
Loan prior to the related Repurchase Date pursuant to Section 8, Buyer's
assigns; provided, however, that the obligations of Seller to service the
Purchased Student Loans shall cease upon the payment by Seller to Buyer of the
Repurchase Price therefor. Seller shall cause each Servicer to service the
related Purchased Student Loans in accordance with the servicing agreements and
in compliance with all applicable federal and state laws, including, in the case
of Purchased Federal Student Loans, the Higher Education Act and in the case of
the Purchased Private Student Loans the servicing guidelines of TERI or those
applicable to TuitionGuard Loans, as applicable.

                                      -22-
<PAGE>
                  (b) Upon the occurrence and continuance of an Event of
Default, Buyer may, in its sole discretion, sell the Purchased Student Loans to
the extent of its interest therein, subject to the servicing agreements relating
to such Purchased Student Loans and, in the case of Purchased Federal Student
Loans, as permitted by the Higher Education Act.

                  (c) Seller agrees that Buyer is the owner of all Servicing
Records with respect to the Purchased Student Loans. Seller covenants to
safeguard such Servicing Records and to deliver them promptly to Buyer or its
designee at Buyer's request.

                  (d) Seller shall cause each Servicer hereunder to execute a
letter agreement with buyer acknowledging Buyer's security interest and agreeing
that, upon notice from Buyer that an Event of Default has occurred and is
continuing hereunder, it shall deposit all Income with respect to the Purchased
Student Loans in the account specified in Section 5(a).

                  Section 26. Miscellaneous. (a) Time is of the essence under
this agreement and all Transactions and all references to a time shall mean New
York time in effect on the date of the action unless otherwise expressly stated
in this Agreement.

                  (b) Buyer shall be authorized to accept orders and take any
other action affecting any accounts of the Seller in response to instructions
given in writing or orally by telephone or otherwise by an officer of the Seller
or any other person authorized in writing by the Seller to act on behalf of the
Seller, and the Seller shall indemnify Buyer and defend and hold Buyer harmless
from and against any and all liabilities, losses, damages, costs, and expenses
of any nature arising out of or in connection with any action taken by Buyer in
response to such instructions received or reasonably believed to have been
received from the Seller. Seller shall further indemnify Buyer and defend and
hold Buyer harmless for any and all amounts due to the related Eligible Lender
Trustee under Section 10 of the Repurchase Trust Agreement, Section 6 of the
related AMS Trust Agreement or otherwise pursuant to such agreement, and the
related Eligible Lender Trustee agrees to look exclusively to Seller and not to
Buyer for the production of such reports. Buyer shall indemnify Seller and
defend and hold Seller harmless against any and all liabilities, losses,
damages, costs, and expenses caused by Buyer's failure to make a timely delivery
of the Purchased Student Loans as required hereunder.

                  (c) If there is any conflict between the terms of a
Confirmation or a corrected Confirmation issued by the Buyer and this Agreement,
the Confirmation or the corrected Confirmation shall prevail, as applicable.

                  (d) This Agreement may be executed in counterparts, each of
which so executed shall be deemed to be an original, but all of such
counterparts shall together constitute but one and the same instrument.

                  (e) Seller agrees to reimburse Buyer for all reasonable costs
and expenses of Buyer in connection with this Agreement including, without
limitation, (i) the fees, expenses and disbursement of counsel to Buyer, (ii)
due diligence expenses up to $75,000, and (iii) on-going auditing fees.

                  (f) The headings in this Agreement are for convenience of
reference only and shall not affect the interpretation or construction of this
Agreement.

                  (g) The parties acknowledge, intend, and agree that (1) all
provisions in this Agreement that require compliance with the Higher Education
Act are enforceable standards of conduct for the parties, and terms and/or
conditions hereof; (2) all provisions of the Higher Education Act, as amended
from time to time, relevant to such provisions in this Agreement are
incorporated by reference into this Agreement with the same force and effect as
if fully stated herein; (3) any assertion in litigation by a party hereto of a
claim or defense based on a violation of any such provision of this Agreement
constitutes a claim or defense based on the agreed upon terms and conditions of
this Agreement, and does not constitute a private claim or defense under the
Higher Education Act or an attempt to enforce or implement the Higher Education
Act through a state law claim or defense; and (4) in any such Higher Education
Action, the party opposing such claim or defense shall not assert or contend
that such claim or defense is either a prohibited private claim or defense under
the Higher Education Act or preempted by the Higher Education Act due to the
Higher Education Act that the provision at issue requires compliance with the
Higher Education Act.

                  Section 27. Private Student Loans. For the avoidance of doubt,
the Buyer and the Seller hereby acknowledge and agree that at any time that the
sublimit for Private Student Loans set forth in Section 12(i)(viii) is equal to
0%, the provisions of this agreement with respect to Private Student Loans and
Purchase Private Student Loans shall have no effect.

                                   EXHIBIT III

                  Representations With Respect to Student Loans

                  (i) Characteristics of Student Loans. Each Student Loan (A)
was originated in the United States of America, its territories, its possessions
or other areas subject to its jurisdiction to an eligible borrower under
applicable laws and agreements and was fully and properly executed by the
parties thereto, (B) was originated or acquired by the Seller (or by the related
AMS Trustee on its behalf) in the ordinary course of its business, and (C)
provides for payments on a periodic basis that fully amortizes the principal
amount of such Student Loan by its maturity, as such maturity may be modified in
accordance with any applicable deferral or forbearance periods granted in
accordance with applicable laws and restrictions or any related guarantee
agreement, and yields interest at the rates applicable thereto. Each Federal
Student Loan was originated by an "eligible lender" under the Higher Education
Act in the ordinary course of its business and is guaranteed by an eligible
guarantor under the Higher Education Act and qualifies the holder thereof to
receive Subsidy Payments from the DOE and guarantee payments from the related
guarantor and qualified the related guarantor to receive reinsurance payments
thereon from the DOE.

                  (ii) Schedule of Student Loans. The information set forth in
the relevant Student Loan Schedule is true and correct in all material respects
as of the date of each Transaction. No selection procedures believed to be
adverse to the Buyer were utilized in selecting any Student Loan. The computer
tape regarding the Student Loans made available to the Buyer is true and correct
in all material respects as of the date of the related Transaction.

                  (iii) Compliance with Law. Each Student Loan complied at the
time of origination and, except as may otherwise be agreed to by Buyer,
complies, at the time of its transfer pursuant to this Agreement, in all
material respects with all applicable requirements of local, state, and federal
laws, rules and regulations which govern the making and servicing of such
Student Loan including the requirements of the applicable Guarantee Agreement
and including, in the case of the Private Student Loans, the TERI or
TuitionGuard Programs, as applicable.

                  (iv) Binding Obligation. All signatures for the Student Loans
are genuine and the note evidencing each Student Loan has been duly executed and
delivered and constitutes the legal, valid, and binding obligation of the
related borrower enforceable in accordance with its terms.

                  (v) No Defenses. No right of rescission, setoff, counterclaim,
or defense has been asserted or threatened or exists with respect to any Student
Loan.

                  (vi) No Default. No Student Loan has a payment that is more
than 120 days delinquent for a Federal Student Loan and 90 days delinquent for a
Private Student Loan as of the date of the related Transaction and, except as
permitted in this paragraph, no default, breach, violation or event permitting
acceleration under the terms of any Student Loan has occurred; and, except for
payment defaults continuing for a period of not more than 120 days for a Federal

                                   EXH. III-1
<PAGE>

Student Loan and 90 days for a Private Student Loan, no continuing condition
that with notice or the lapse of time or both would constitute a default,
breach, violation or event permitting acceleration under the terms of any
Student Loan has arisen; and the Seller has not waived and shall not waive any
of the foregoing.

                  (vii) Title. With respect to Federal Student Loans,
immediately prior to the transfer and sale of each Student Loan to Buyer, the
Seller owned beneficial ownership of each Student Loan, and the related AMS
Trustee held legal title to such Student Loan, free and clear of any lien,
charge, encumbrance, or other interest therein and immediately upon the transfer
and sale of beneficial ownership of such Student Loan to the Buyer, the Buyer
will own such beneficial ownership interest in such Student Loan free and clear
of any lien, charge, encumbrance, or other interest therein (subject in each
case to the retention of legal title thereto by the related AMS Trustee and the
holding of such beneficial ownership interest by the related Eligible Lender
Trustee on its behalf). With respect to Private Student Loans, immediately prior
to the transfer and sale of each Student Loan to Buyer, the Seller owned each
Student Loan, free and clear of any lien, charge, encumbrance, or other interest
therein and immediately upon the transfer and sale of such Student Loan to the
Buyer, the Buyer will own such Student Loan free and clear of any lien, charge,
encumbrance, or other interest therein. The Seller's computer files relating to
the Student Loans have been marked to indicate that such Student Loans have been
sold to the Buyer. Notwithstanding the foregoing, Purchaser acknowledges that
Seller may have pledged certain subordinated interests in such Purchased Student
Loans to UICI.

                  (viii) All Filings Made. All filings (including UCC filings)
necessary in any jurisdiction to give the Buyer a first perfected ownership
interest in the Student Loans (in the case of the Federal Student Loans as
limited by the Higher Educational Act, and the provisions of this Agreement)
have been made.

                  (ix) Security Interest. The related Eligible Lender Trustee
has a perfected, first priority security interest for the benefit of the Buyer
in each Student Loan.

                  (x) No Bankruptcies. To the best of the Seller's knowledge, no
borrower as of the date of the related Transaction was involved in a bankruptcy
proceeding.

                  (xi) Lawful Assignment. No Student Loan (except, with respect
to Federal Student Loans, as provided in the Higher Education Act) has been
originated in, or is subject to the laws of, any jurisdiction under which the
origination, sale, transfer and assignment of such Student Loan or beneficial
ownership therein is unlawful, void or voidable.

                  (xii) One Original. There is only one original executed copy
of the promissory note evidencing each Student Loan.

                  (xiii) Accounts. Each Student Loan may be pledged or
transferred as an "account" or a "general intangible" as defined in the UCC.

                  (xiv) Disbursement Order. No Student Loan is a subsequent
disbursement unless all of the related first or other prior disbursements under
such Student Loans are Purchased Student Loans. (i)

such covenants, agreements and obligations on the part of the Seller to be paid
or performed and together with all covenants or other obligations in the
Agreement ascribed to the Guarantor (and, in each case, regardless of whether
incurred after the commencement of any bankruptcy proceeding with respect to
Seller) being collectively called the "Obligations"); provided, that, the
aggregate amount for which the Guarantor will be liable with respect to the
Obligations shall not exceed $13,333,333.33 plus any and all amounts for which
Guarantor becomes obligated under clause (a) above or pursuant to the last
paragraph of Section 2 hereof. In the event that the Seller shall fail in any
manner whatsoever to perform or pay, when required in accordance with the terms
of the Agreement, any of the Obligations, then Guarantor will perform and pay,
or cause to be duly and punctually performed or paid, the Obligations (limited
as provided above with respect to the Obligations set forth in clause (b)
above). In no event shall Guarantor be liable for the nonperformance,
nonobservance or nonpayment of any Person, other than nonperformance,

                                      -1-
<PAGE>

nonobservance or nonpayment of obligations undertaken by the Seller under the
Agreement. All payments to be made by the Guarantor hereunder shall be made when
due, without set-off or counterclaim, to LBB at its address set forth below or
to such other location or account as LBB shall specify in writing to the
Guarantor in United States dollars and in immediately available funds. Guarantor
hereby represents and warrants that its obligations hereunder do and shall rank
pari passu with all senior unsecured and unsubordinated indebtedness of
Guarantor.

         The obligations of the Guarantor hereunder shall not be discharged,
impaired or otherwise affected by, to the maximum extent permitted by law, (a)
the failure of LBB to assert any claim or demand or to enforce any right or
remedy against the Seller (including but not limited to LBB's rights and
remedies with respect to the Purchased Student Loans) under the provisions of
the Agreement or any document related thereto or otherwise; (b) any extension or
renewal of any part of the Obligations; (c) any rescission, waiver, amendment or
modification of any of the terms or provisions of the Agreement or of any
document related thereto; (d) the bankruptcy, insolvency or reorganization of
the Seller; (e) the invalidity or unenforceability of any of the Obligations or
(f) any other event which under law would discharge the obligations of a surety.
The Guarantor acknowledges that LBB has been induced to enter into the Agreement
in reliance on this Guaranty. This Guaranty shall be construed as a continuing,
absolute and unconditional guarantee of payment, and not of collection. This
Guaranty shall remain in full force and effect until the Obligations are paid in
full and the commitment under the Agreement or any document related thereto is
terminated, notwithstanding that from time to time prior thereto the Seller may
be free from any Obligations.

         Guarantor hereby specifically agrees that Guarantor shall not, to the
maximum extent permitted by law, be released from liability hereunder by any
action taken or omitted to be taken by LBB, the Seller or any of their
respective Affiliates, employees, agents or representatives, including, without
limitation, a non-judicial sale of property subject to the Agreement that would
afford the Seller or the Guarantor a defense based upon the laws (including the
anti-deficiency laws) of any state. Guarantor expressly waives, to the maximum
extent permitted by law, (i) any defense to the recovery of a deficiency against
the Seller or the Guarantor hereunder after such non-judicial sale and (ii) all
suretyship defenses that it would otherwise have under the laws of any
jurisdiction. The Guarantor expressly agrees that the Guarantor shall be and
remain liable for any deficiency, to the maximum extent permitted by law,
remaining after the sale of the Purchased Student Loans (including foreclosure
of any security interest), whether or not the liability of the Seller for such
deficiency is discharged pursuant to statute or judicial decision.

         The Guarantor waives, to the maximum extent permitted by law,
diligence, presentment, protest, demand for payment and notice of default or
nonpayment and all other notices of any kind to or upon the Guarantor with
respect to the Obligations.

         The Guarantor agrees that the Obligations may at any time and from time
to time exceed the amount of the liability of such Guarantor hereunder without
impairing this Guaranty or affecting the rights and remedies of LBB hereunder.

         No payment or payments made by the Seller, the Guarantor, any other
guarantor or any other Person or received or collected by LBB from the Seller,
the Guarantor, any other

                                      -2-
<PAGE>

guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of the Guarantor hereunder which
shall, notwithstanding any such payment or payments other than payments made by
the Guarantor in respect of the Obligations or payments received or collected
from the Guarantor in respect of the Obligations, remain liable for the
Obligations up to the maximum liability of the Guarantor hereunder until the
Obligations are paid in full and the commitment is terminated.

         The Guarantor agrees that whenever, at any time, or from time to time,
it shall make any payment to LBB on account of its liability hereunder, it will
notify LBB in writing that such payment is made under this Guaranty for such
purpose.

         Section 2. Representations and Warranties of Guarantor. Guarantor
represents and warrants to LBB as follows:

         (a) It has been duly organized and is validly existing as a corporation
in good standing under the laws of the State of Delaware, with corporate power
and authority to own its properties and to conduct its business as such
properties shall be currently owned and such business is presently conducted.

         (b) It is duly qualified to do business as a foreign corporation in
good standing, and has obtained all necessary licenses and approvals in all
jurisdictions in which the ownership or lease of property or the conduct of its
businesses shall require such qualifications, licenses or approvals, except
where the failure to obtain such qualifications, licenses or approvals would not
reasonably be expected to have a material adverse effect on the financial
condition, operations, business or prospects of Guarantor.

         (c) It has the corporate power and authority to execute and deliver
this Guaranty and to carry out its terms.

         (d) The consummation of the transactions contemplated by this Guaranty
and the fulfillment of the terms hereof shall not conflict with, result in any
breach of any of the terms and provisions of, nor constitute (with or without
notice or lapse of time) a default under, the certificate of incorporation or
by-laws of the Guarantor, or any indenture, agreement, or other instrument to
which it is a party or by which it shall be bound; nor 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, other than this Guaranty, nor
violate any law or any order, rule, or regulation applicable to it of any court
or of any federal or state regulatory body, administrative agency, or other
governmental instrumentality having jurisdiction over it or its properties.

         (e) There are no proceedings or investigations pending, or, to the
knowledge of the Guarantor, threatened, before any court, regulatory body,
administrative agency, or other governmental instrumentality having jurisdiction
over it or its properties: (i) asserting the invalidity of this Guaranty; (ii)
seeking to prevent the consummation of any of the transactions contemplated by
this Guaranty; or (iii) seeking any determination or ruling that would

                                      -3-
<PAGE>

reasonably be expected to have a material adverse effect on the business,
results of operations, financial condition or prospects of the Guarantor, or the
performance by the Guarantor of its obligations under, or the validity or
enforceability of, this Guaranty.

         (f) All approvals, authorizations, consents, orders or other actions or
registrations with any person or any governmental body or official required to
be obtained on or prior to the date hereof in connection with the execution and
delivery of this Guaranty, the performance of the transactions contemplated by
this Guaranty and the fulfillment of the terms hereof have been obtained.

         In addition, Guarantor represents, warrants and covenants to LBB that
each Purchased Student Loan sold under the Agreement and each pool of Purchased
Student Loans sold in a Transaction under the Agreement, as of the related
Purchase Date will conform to the representations and warranties set forth in
Exhibit III attached to the Agreement and that each Student Loan delivered under
the Agreement as Additional Student Loans or Substituted Student Loans, as of
the date of such delivery, will conform to the representations and warranties
set forth in Exhibit III attached to the Agreement. Guarantor further
represents, warrants and covenants to LBB that (i) the Computer Tape with
respect to each Purchased Student Loan is complete, true and correct as of the
last calendar day of each month, (ii) all Purchased Federal Student Loans will
be serviced in accordance with applicable provisions of the Higher Education Act
and all Purchased Private Student Loans will be serviced in accordance with
applicable requirements of TERI, (iii) it will not create, incur or permit to
exist any lien, encumbrance or security interest in or on any of the Purchased
Student Loans or its beneficial interest therein (other than the security
interest described in Section 6 of the Agreement or permitted under the
Subordination and Intercreditor Agreement) without the prior express written
consent of LBB, (iv) Guarantor shall not permit the Purchased Student Loans to
contain (1) any Federal Student Loan which is more than 120 days delinquent, (2)
any Private Student Loan which is more than 90 days delinquent, (3) more than 5%
by aggregate Purchase Price of Student Loans that are more than 30 days
delinquent, (4) more than 2.5% by aggregate Purchase Price of Student Loans that
are more than 60 days delinquent, (5) any Federal Student Loan as to which the
applicable federal guarantor's obligation to make guaranty payments or the
federal reinsurance with respect thereto has for any reason been forfeited or
qualified, (6) any Private Student Loan as to which the obligation of TERI to
make guaranty payments under the TERI Guaranty Agreement has for any reason been
forfeited or qualified or (7) more than 20% by aggregate Purchase Price of
Student Loans that are Private Student Loans, and (v) Guarantor shall take all
actions necessary to ensure that each Federal Student Loan is subject to a
Guaranty Agreement and that each Private Student Loan is subject to a TERI
Guaranty Agreement. As a further inducement to LBB entering into the Agreement,
Guarantor hereby agrees to purchase any Purchased Student Loans as to which
there has occurred a breach of any of the representations, warranties or
covenants made by it pursuant to this paragraph (or in the case of clause (iv),
above, a sufficient number of Purchased Student Loans to cause compliance with
the applicable provision) at a price equal to the unpaid principal balance of
the applicable Purchased Student Loans (such balance to include, in the case of
Federal Student Loans, accrued interest that is not then payable but is to be
capitalized and added to principal) plus accrued and unpaid interest thereon.
LBB agrees that the purchase price of any loans purchased by Guarantor pursuant
to this paragraph will be counted against the Repurchase Price then outstanding
under the Agreement.

                                      -4-
<PAGE>

         Section 3. No Subrogation, etc. Guarantor hereby waives all rights of
subrogation, contribution, reimbursement, indemnity or otherwise, whether
arising by contract or operation of law (including, without limitation, any such
right arising under the Federal Bankruptcy Code) or otherwise by reason of any
payment by Guarantor pursuant to the provisions of this Guaranty until such time
as the Obligations have been indefeasibly paid in full. The parties acknowledge
that such waivers shall not apply to payments by Guarantor hereunder that
constitute (x) Permitted Indebtedness or indebtedness of the Seller fully
subject to the Subordination and Intercreditor Agreement or (y) a purchase of
Purchased Student Loans by Guarantor or (z) a purchase of Purchased Student
Loans by Seller or any affiliated third party financed in whole or in part by
Guarantor. In addition, Guarantor agrees that any payment by it hereunder shall
be made in the form of either (x), (y) or (z) as set forth in the preceding
sentence; provided that, no purchase of Purchased Student Loans pursuant to
clauses (y) or (z) shall occur unless, after giving effect to any such purchase,
no Collateral Deficit or Event of Default shall exist under the Agreement. The
parties agree that the Purchased Student Loans subject to any such purchase
shall have been selected by LBB acting reasonably in selecting a portfolio
representative of the entire pool. If any amount shall be paid to the Guarantor
on account of such subrogation rights at any time when all of the Obligations
shall not have been paid in full, such amount shall be held by the Guarantor in
trust for LBB, segregated from other funds of the Guarantor, and shall,
forthwith upon receipt by the Guarantor, be turned over to LBB in the exact form
received by the Guarantor (duly indorsed by the Guarantor to LBB, if required),
to be applied against the Obligations, whether matured or unmatured, in such
order as LBB may determine.

         Section 4. Obligations Absolute. The Guarantor shall remain obligated
hereunder notwithstanding that, without any reservation of rights against the
Guarantor and without notice to or further assent by the Guarantor, any demand
for payment of any of the Obligations made by LBB may be rescinded by such party
and any of the Obligations continued, and the Obligations, or the liability of
any other party upon or for any part thereof, or any collateral security or
guaranty therefor or right of offset with respect thereto, may, from time to
time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by LBB, and the Agreement and any
other documents executed and delivered in connection therewith may be amended,
modified, supplemented or terminated, in whole or in part, as LBB may deem
advisable from time to time, and any collateral security, guaranty or right of
offset at any time held by LBB for the payment of the Obligations may be sold,
exchanged, waived, surrendered or released. LBB shall not have any obligation to
protect, secure, perfect or insure any Lien at any time held by it as security
for the Obligations or for this Guaranty or any property subject thereto. When
making any demand hereunder against the Guarantor, LBB may, but shall be under
no obligation to, make a similar demand on the Seller or any other guarantor,
and any failure by LBB to make any such demand or to collect any payments from
the Seller or any such other guarantor or any release of the Seller or such
other guarantor shall not relieve the Guarantor of its obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of LBB against the Guarantor. For the
purposes hereof "demand" shall include the commencement and continuance of any
legal proceedings.

         Section 5. Guaranty Absolute and Unconditional. The Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice

                                      -5-
<PAGE>

of or proof of reliance by LBB upon this Guaranty or acceptance of this
Guaranty, the Obligations, and any of them, shall conclusively be deemed to have
been created, contracted or incurred, or renewed, extended, amended or waived,
in reliance upon this Guaranty; and all dealings between the Seller and the
Guarantor, on the one hand, and LBB, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon this
Guaranty. The Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Seller or the
Guarantor with respect to the Obligations. The Guarantor understands and agrees
that this Guaranty shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity,
regularity or enforceability of the Agreement or any document related thereto,
any of the Obligations or any other collateral security therefor or guarantee or
right of offset with respect thereto at any time or from time to time held by
LBB, (b) any defense, set-off or counterclaim (other than a defense of payment
or performance) which may at any time be available to or be asserted by the
Seller against LBB, or (c) any other circumstance whatsoever (with or without
notice to or knowledge of the Seller or the Guarantor) which constitutes, or
might be construed to constitute, an equitable or legal discharge of the Seller
for the Obligations, or of the Guarantor under this Guaranty, in bankruptcy or
in any other instance. When pursuing its rights and remedies hereunder against
the Guarantor, LBB may, but shall be under no obligation to, pursue such rights
and remedies as it may have against the Seller or any other Person or against
any collateral security or guaranty for the Obligations or any right of setoff
with respect thereto, and any failure by LBB to pursue such other rights or
remedies or to collect any payments from the Seller or any such other Person or
to realize upon any such collateral security or guaranty or to exercise any such
right of offset, or any release of the Seller or any such other Person or any
such collateral security, guaranty or right of setoff, shall not relieve the
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of LBB
against the Guarantor. This Guaranty shall remain in full force and effect and
be binding in accordance with and to the extent of its terms upon the Guarantor
and the successors and assigns thereof, and shall inure to the benefit of LBB,
and its successors, endorsees, transferees and assigns, until all the
Obligations have been satisfied or the obligations of the Guarantor under this
Guaranty shall have been satisfied by payment in full and the Agreement shall be
terminated, notwithstanding that from time to time during the term of the
Agreement the Seller may be free from any Obligations.

         Section 6. Attorney's Fees. In the event that, upon the occurrence of
an Event of Default under the Agreement or a default or other breach by
Guarantor hereunder, LBB for any reason whatsoever shall deem it necessary to
refer this Guaranty to an attorney for the enforcement thereof or of any rights
hereunder or otherwise, there shall be immediately due from Guarantor to LBB,
reasonable attorneys' fees and disbursements, together with all costs and
expenses of such action.

         Section 7. Amendments in Writing; No Waiver; Cumulative Remedies.

         (a) None of the terms or provisions of this Guaranty may be waived,
amended, supplemented or otherwise modified except by a written instrument
executed by the Guarantor and LBB; provided, that any provision of this Guaranty
may be waived by LBB in a letter or agreement executed by LBB or by telex or
facsimile transmission from LBB.

                                      -6-
<PAGE>

         (b) LBB shall not by any act (except by a written instrument pursuant
to Section 7(a) hereof), delay, indulgence, omission or otherwise be deemed to
have waived any right or remedy hereunder or to have acquiesced in any default
or Event of Default or in any breach of any of the terms and conditions hereof.
No failure to exercise, nor any delay in exercising, on the part of LBB, any
right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial exercise of any right, power or privilege hereunder shall preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. A waiver by LBB of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy that LBB would
otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

         Section 8. Addresses for Notices. All notices and other communications
provided for hereunder shall be in writing (including facsimile communication)

         Section 9. Right of Set-off. In addition to any rights and remedies of
LBB provided by law or otherwise, LBB shall have the right, without prior notice
to Guarantor, any such notice being expressly waived by Guarantor to the extent
permitted by applicable law, to set off, appropriate and apply against any
amount becoming due and payable by Guarantor hereunder such amount against any

such set-off, appropriation and application.

         Section 10. Reinstatement. This Guaranty shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by LBB upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of Seller or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for,
Seller or any substantial part of its property, or otherwise, all as though such
payments had not been made.

         Section 11. Successors and Assigns. This Guaranty shall (i) be binding

         Section 14. Miscellaneous. The headings in the Guaranty are for
purposes of reference only and shall not limit or define the meaning hereof.
This Guaranty may be executed in any number of counterparts, each of which shall
be an original, but all of which shall constitute one instrument. In the event

provisions of this Guaranty that shall remain binding on all parties hereto.

         Section 15. Governing Law. This Guaranty shall be governed by, and
construed in accordance with, the laws of the State of New York applicable to
