SECTION 6. PURCHASE OF TRUST STUDENT LOANS; REIMBURSEMENT

Each party to these Master Terms shall give notice to the other parties promptly, in writing, upon the discovery of any breach of Sallie Mae’s representations and warranties made pursuant to Section 5(A) and (B) hereof which has a materially adverse effect on the interest of Funding in any Trust Student Loan. In the event of such a material breach which is not curable by reinstatement of the Guarantor’s guarantee of such Trust Student Loan, Sallie Mae shall repurchase any affected Trust Student Loan not later than 120 days following the earlier of the date of discovery of such material breach and the date of receipt of the Guarantor reject

transmittal form with respect to such Trust Student Loan. In the event of such a material breach which is curable by reinstatement of the Guarantor’s guarantee of such Trust Student Loan, unless the material breach shall have been cured within 360 days following the earlier of the date of discovery of such material breach and the date of receipt of the Guarantor reject transmittal form with respect to such Trust Student Loan, Sallie Mae shall purchase such Trust Student Loan not later than the sixtieth day following the end of such 360-day period. Sallie Mae shall also remit as provided in Section 2.6 of the Administration Agreement on the date of purchase of any Trust Student Loan pursuant to this Section 6 an amount equal to all non-guaranteed interest amounts and forfeited Interest Subsidy Payments and Special Allowance Payments with respect to such Trust Student Loan. In consideration of the purchase of any such Trust Student Loan pursuant to this Section 6, Sallie Mae shall remit the Purchase Amount in the manner specified in Section 2.6 of the Administration Agreement.

In addition, if any breach of Section 5(A) and (B) hereof by Sallie Mae does not trigger such purchase obligation but does result in the refusal by a Guarantor to guarantee all or a portion of the accrued interest (or any obligation of Funding to repay such interest to a Guarantor), or the loss (including any obligation of Funding to repay the Department) of Interest Subsidy Payments and Special Allowance Payments, with respect to any Trust Student Loan affected by such breach, then Sallie Mae shall reimburse Funding by remitting an amount equal to the sum of all such non-guaranteed interest amounts and such forfeited Interest Subsidy Payments or Special Allowance Payments in the manner specified in Section 2.6 of the Administration Agreement not later than (i) the last day of the next Collection Period ending not less than 60 days from the date of the Guarantor’s refusal to guarantee all or a portion of accrued interest or loss of Interest Subsidy Payments or Special Allowance Payments, or (ii) in the case where Sallie Mae reasonably believes such losses are likely to be collected, not later than the last day of the next Collection Period ending not less than 360 days from the date of the Guarantor’s refusal to guarantee all or a portion of accrued interest or loss of Interest Subsidy Payments or Special Allowance Payments. At the time such payment is made, Sallie Mae shall not be required to reimburse Funding for interest that is then capitalized, however, such amounts shall be reimbursed if the borrower subsequently defaults and such capitalized interest is not paid by the Guarantor.

Anything in this Section 6 to the contrary notwithstanding, if as of the last Business Day of any month the aggregate outstanding principal amount of Trust Student Loans with respect to which claims have been filed with and rejected by a Guarantor or with respect to which the Servicer determines that claims cannot be filed pursuant to the Higher Education Act as a result of a breach by Sallie Mae or the Servicer, exceeds 1% of the Pool Balance, Sallie Mae (and the Servicer as provided in the Servicing Agreement) shall purchase, within 30 days of a written request of the Eligible Lender Trustee or the Indenture Trustee, such affected Trust Student Loans in an aggregate principal amount such that after such purchase the aggregate principal amount of such affected Trust Student Loans is less than 1% of the Pool Balance. The Trust Student Loans to be purchased by Sallie Mae and the Servicer pursuant to the preceding sentence shall be based on the date of claim rejection (or the date of notice referred to in the first sentence of this Section 6) with Trust Student Loans with the earliest such date to be purchased first.

In lieu of repurchasing Trust Student Loans pursuant to this Section 6, Sallie Mae may, at its option, substitute Eligible Loans or arrange for the substitution of Eligible Loans which are

substantially similar on an aggregate basis as of the date of substitution to the Trust Student Loans for which they are being substituted with respect to the following characteristics:

1. status (i.e., in-school, grace, deferment, forbearance or repayment),

2. program type (i.e., Unsubsidized or Subsidized Consolidation (pre-1993 vs. post-1993)),

3. school type,

4. total return,

5. principal balance, and

6. remaining term to maturity.

In addition, each substituted Eligible Loan will comply, as of the date of substitution, with all of the representations and warranties made hereunder. In choosing Eligible Loans to be substituted pursuant to this Section 6, Sallie Mae shall make a reasonable determination that the Eligible Loans to be substituted will not have a material adverse effect on the Noteholders.

In the event that Sallie Mae elects to substitute Eligible Loans pursuant to this Section 6, Sallie Mae will remit to the Administrator the amount of any shortfall between the Purchase Amount of the substituted Eligible Loans and the Purchase Amount of the Trust Student Loans for which they are being substituted. Sallie Mae shall also remit to the Administrator an amount equal to all non-guaranteed interest amounts and forfeited Interest Subsidy Payments and Special Allowance Payments with respect to the Trust Student Loans in the manner provided in Section 2.6 of the Administration Agreement. The sole remedy of Funding, the Eligible Lender Trustee and the Noteholders with respect to a breach by Sallie Mae pursuant to Section 5(A) and (B) hereof shall be to require Sallie Mae to purchase Trust Student Loans, to reimburse Funding as provided above or to substitute Student Loans pursuant to this Section. The Eligible Lender Trustee shall have no duty to conduct any affirmative investigation as to the occurrence of any condition requiring the purchase of any Trust Student Loan or the reimbursement for any interest penalty pursuant to this Section 6.

SECTION 7. OBLIGATION TO REMIT SUBSEQUENT PAYMENTS AND FORWARD COMMUNICATIONS

(A) Any payment received by Sallie Mae with respect to amounts accrued after the Date of the Bill of Sale for any Loan sold to Funding, which payment is not reflected in the Loan Transmittal Summary Form, shall be received by Sallie Mae in trust for the account of Funding and Sallie Mae hereby disclaims any title to or interest in any such amounts. Within two (2) Business Days following the date of receipt, Sallie Mae shall remit to Funding an amount equal to any such payments along with a listing on a form provided by Funding identifying the Loans with respect to which such payments were made, the amount of each such payment and the date each such payment was received.

(B) Any written communication received at any time by Sallie Mae with respect to any Loan subject to this Purchase Agreement shall be transmitted by Sallie Mae to Servicer within two (2) Business Days of receipt.

SECTION 8. CONTINUING OBLIGATION OF SALLIE MAE

Sallie Mae shall provide all reasonable assistance necessary for Funding to resolve account problems raised by any Borrower, the Guarantor or the Secretary provided such account problems are attributable to or are alleged to be attributable to (a) an event occurring during the period Sallie Mae owned the Loan, or (b) a payment made or alleged to have been made to Sallie Mae.

Sallie Mae shall not be under any obligation to appear in, prosecute or defend any legal action that shall not be incidental to its obligations under these Master Terms or any Purchase Agreement, and that in its opinion may involve it in any expense or liability. Except as provided herein, the repurchase (or substitution) and reimbursement obligations of Sallie Mae will constitute the sole remedy available to Funding for uncured breaches; provided, however, that the information with respect to the Loans listed on the Bill of Sale may be adjusted in the ordinary course of business subsequent to the date of the Bill of Sale and to the extent that the aggregate Principal Balance of the Loans listed on the Bill of Sale is less than the aggregate Principal Balance stated on the Bill of Sale, Sallie Mae shall remit such amount to the Interim Eligible Lender Trustee, for the benefit of and on behalf of Funding. Such reconciliation payment shall be made from time to time but no less frequently than semi-annually.

SECTION 12. LIMITATION OF LIABILITY OF INTERIM ELIGIBLE LENDER

Notwithstanding anything contained herein to the contrary, these Master Terms and any Purchase Agreement have been signed by Chase Manhattan Bank USA, National Association, not in its individual capacity but solely in its capacity as Interim Eligible Lender Trustee for Funding and in no event shall Chase Manhattan Bank USA, National Association in its individual capacity have any liability for the representations, warranties, covenants, agreements or other obligations of Funding, under these Master Terms or any Purchase Agreement or in any of the certificates, notices or agreements delivered pursuant hereto, as to all of which recourse shall be had solely to the assets of Funding.

SECTION 13. EXPENSES

Except as otherwise provided herein, each party to these Master Terms or any Purchase Agreement shall pay its own expense incurred in connection with the preparation, execution and delivery of these Master Terms and any Purchase Agreement and the transactions contemplated herein or therein.

SECTION 14. SURVIVAL OF COVENANTS/SUPERSESSION

All covenants, agreements, representations and warranties made herein and in or pursuant to any Purchase Agreements executed pursuant to these Master Terms shall survive the consummation of the purchase of the Loans provided for in each Purchase Agreement. All covenants, agreements, representations and warranties made or furnished pursuant hereto by or on behalf of Sallie Mae shall bind and inure to the benefit of any successors or assigns of Funding and shall survive with respect to each Loan. Each Purchase Agreement supersedes all previous agreements and understandings between Funding and Sallie Mae with respect to the subject matter thereof. These Master Terms and any Purchase Agreement may be changed, modified or discharged, and any rights or obligations hereunder may be waived, only by a

written instrument signed by a duly authorized officer of the party against whom enforcement of any such waiver, change, modification or discharge is sought. The waiver by Funding of any covenant, agreement, representation or warranty required to be made or furnished by Sallie Mae or the waiver by Funding of any provision herein contained or contained in any Purchase Agreement shall not be deemed to be a waiver of any breach of any other covenant, agreement, representation, warranty or provision herein contained, nor shall any waiver or any custom or practice which may evolve between the parties in the administration of the terms hereof or of any Purchase Agreement, be construed to lessen the right of Funding to insist upon the performance by Sallie Mae in strict accordance with said terms.

SECTION 15. COMMUNICATION AND NOTICE REQUIREMENTS

All communications, notices and approvals provided for hereunder shall be in writing and mailed or delivered to Sallie Mae or Funding, as the case may be, addressed as set forth in the Purchase Agreement or at such other address as either party may hereafter designate by notice to the other party. Notice given in any such communication, mailed to Sallie Mae or Funding by appropriately addressed registered mail, shall be deemed to have been given on the day following the date of such mailing.

SECTION 16. FORM OF INSTRUMENTS

All instruments and documents delivered in connection with these Master Terms and any Purchase Agreement, and all proceedings to be taken in connection with these Master Terms and any Purchase Agreement and the transactions contemplated herein and therein, shall be in a form as set forth in the attachments hereto, and Funding shall have received copies of such documents as it or its counsel shall reasonably request in connection therewith. Any instrument or document which is substantially in the same form as an Attachment hereto or a recital herein will be deemed to be satisfactory as to form.

SECTION 17. AMENDMENT

These Master Terms and any Purchase Agreement may be amended by the parties thereto without the consent of the related Noteholders for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of such Master Terms and Purchase Agreements or of modifying in any manner the rights of such Noteholders; provided that such action will not, in the opinion of counsel satisfactory to the related Indenture Trustee, materially and adversely affect the interest of any such Noteholder.

In addition, these Master Terms and any Purchase Agreement may also be amended from time to time by Sallie Mae, the Interim Eligible Lender Trustee and Funding, with the consent of the Noteholders of Notes evidencing a majority of the Outstanding Amount of the Notes, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of these Master Terms or any Purchase Agreements or of modifying in any manner the rights of the Noteholders; provided, however, that no such amendment shall (a) increase or reduce in any manner the amount of, or accelerate or delay the time of, collections of payments with respect to Loans or distributions that shall be required to be made for the benefit of the Noteholders or (b) reduce the aforesaid percentage of the Outstanding Amount of the Notes, the

Noteholders of which are required to consent to any such amendment, without the consent of all outstanding Noteholders.

Promptly after the execution of any such amendment or consent (or, in the case of the Rating Agencies, five Business Days prior thereto), the Interim Eligible Lender Trustee shall furnish written notification of the substance of such amendment or consent to the Indenture Trustee and each of the Rating Agencies.

It shall not be necessary for the consent of Noteholders pursuant to this Section to approve the particular form of any proposed amendment or consent, but it shall be sufficient if such consent shall approve the substance thereof.

Prior to the execution of any amendment to these Master Terms, the Interim Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of Counsel stating that execution of such amendment is authorized or permitted by these Master Terms and the Opinion of Counsel referred to in Section 7.1(i)(i) of the Administration Agreement. The Interim Eligible Lender Trustee may, but shall not be obligated to, enter into any such amendment which affects the Interim Eligible Lender Trustee’s own rights, duties or immunities under these Master Terms or otherwise.

SECTION 18. NONPETITION COVENANTS

Notwithstanding any prior termination of these Master Terms Sallie Mae and the Interim Eligible Lender Trustee shall not acquiesce, petition or otherwise invoke or cause Funding to invoke the process of any court or government authority for the purpose of commencing or sustaining a case against Funding under any Federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignees, trustee, custodian, sequestrator or other similar official of Funding or any substantial part of its property, or ordering the winding up or liquidation of the affairs of the Funding.

SECTION 19. GOVERNING LAW

These Master Terms and any Purchase Agreement shall be governed by and construed in accordance with the laws of the State of New York without reference to its conflict of law provisions, and the obligations, rights and remedies of the parties, hereunder shall be determined in accordance with such laws.

IN WITNESS WHEREOF, the parties hereto have caused these Master Terms to be duly executed by their respective officers hereunto duly authorized, as of the day and year first above written.
