SECTION 6. REPURCHASE OF TRUST STUDENT LOANS; REIMBURSEMENT

(A) Each party to these Master Terms shall give notice to the other parties promptly, in writing, upon the discovery of any breach of Mustang Funding I’s representations and warranties made pursuant to Sections 5(A) and (B) hereof or the Servicer’s representations and warranties made pursuant to Section 5(C) 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 applicable Guarantor’s guarantee of such Trust Student Loan, Mustang Funding I 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, Mustang Funding I shall purchase such Trust Student Loan not later than the sixtieth day following the end of such 360-day period. Mustang Funding I shall also remit as provided in Section 2.6 of the Administration Agreement on the date of repurchase of any Trust Student Loan pursuant to this Section 6(A) 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(A), Mustang Funding I shall remit the Purchase Amount in the manner specified in Section 2.6 of the Administration Agreement.

In addition, if any breach of Sections 5(A) and (B) hereof by Mustang Funding I or Section 5(C) hereof by the Servicer does not trigger such repurchase 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 Mustang Funding I 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 Mustang Funding I 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, Mustang Funding I 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(A) 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 Mustang Funding I or the Servicer, exceeds 1% of the Pool Balance, Mustang Funding I (or the Servicer as provided in the Servicing Agreement) shall purchase, within 30 days of a written request of 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 Mustang Funding I 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(A)) with Trust Student Loans with the earliest such date to be repurchased first.

(B) In lieu of repurchasing Trust Student Loans pursuant to Section 6(A), Mustang Funding I 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:

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

program type (i.e., Unsubsidized Stafford Loan or Subsidized Stafford Loan (pre-1993 vs. post-1993), PLUS Loan or SLS Loan),

guarantee percentage,

school type,

total return,

principal balance, and

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(B), Mustang Funding I shall make a reasonable determination that the Eligible Loans to be substituted will not have a material adverse effect on the Noteholders. In connection with each substitution a Purchase Agreement and related Bill of Sale regarding such Substituted Loans will be executed and delivered by the applicable parties.

In the event that Mustang Funding I elects to substitute Eligible Loans pursuant to this Section 6(B), Mustang Funding I 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. Mustang Funding I 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.

(C) The sole remedy of Funding, the Eligible Lender Trustee and the Noteholders with respect to a breach by Mustang Funding I pursuant to Sections 5(A) and (B) or the Servicer pursuant to Section 5(C) hereof shall be to require Mustang Funding I to purchase such Trust Student Loans, to reimburse Funding as provided in Section 6(A) above or to substitute Eligible Loans pursuant to Section 6(B) above. 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 Mustang Funding I with respect to amounts accrued after the date of the related Bill of Sale for any Purchased Loan sold to Funding, which payment is not reflected in the related Loan Transmittal Summary Form, shall be received by Mustang Funding I in trust for the account of Funding and Mustang Funding I hereby disclaims any title to or interest in any such amounts. Within two (2) Business Days following the date of receipt, Mustang Funding I shall remit to Funding an amount equal to any such payments along with a listing on a form provided by Funding identifying the Purchased 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 Mustang Funding I with respect to any Loan subject to these Master Terms or the related Purchase Agreement shall be transmitted by Mustang Funding I to the Servicer within two (2) Business Days of receipt. Such communications shall include, but not be limited to, letters, notices of death or disability, notices of bankruptcy, forms requesting deferment of repayment or loan cancellation, and like documents.

SECTION 8. CONTINUING OBLIGATION OF THE SELLER

Mustang Funding I 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 Mustang Funding I or the Mustang Funding I Eligible Lender Trustee owned the related Purchased Loan, or (b) a payment made or alleged to have been made to Mustang Funding I. Further, Mustang Funding I and the Mustang Funding I Eligible Lender Trustee shall agree that either Mustang Funding I or the Mustang Funding I Eligible Lender Trustee shall reasonably cooperate in the preparation and filing of any financing statements at the request of Funding in order to reflect Funding’s interest in the Loans.

SECTION 9. LIABILITY OF THE SELLER; INDEMNITIES

The Servicer shall be liable in accordance herewith only to the extent of the obligations specifically undertaken by the Servicer on behalf of Mustang Funding I under these Master Terms and each related Purchase Agreement.

(i) The Servicer, in consideration for continuing to receive the servicing fee provided in Section 3.6 of the Servicing Agreement shall indemnify, defend and hold harmless Funding and the Interim Eligible Lender Trustee in its individual capacity and their officers, directors, employees and agents from and against any taxes that may at any time be asserted against any such Person with respect to the transactions contemplated herein and in the other Basic Documents (except any such income taxes arising out of fees paid to the Interim Eligible Lender Trustee), including any sales, gross receipts, general corporation, tangible and intangible personal property, privilege or license taxes (but, in the case of Funding, not including any taxes asserted with respect to, and as of the date of, the sale of the Purchased Loans to the Interim Eligible Lender Trustee on behalf of Funding, or asserted with respect to ownership of the Trust Student Loans) and costs and expenses in defending against the same.

(ii) The Servicer, in consideration for continuing to receive the servicing fee shall indemnify, defend and hold harmless Funding and the Interim Eligible Lender Trustee in its individual capacity, and the officers, directors, employees and agents of Funding and the Interim Eligible Lender Trustee from and against any and all costs, expenses, losses, claims, damages and liabilities arising out of, or imposed upon such Person through, Mustang Funding I’s or the Servicer’s, as applicable, willful misfeasance, bad faith or gross negligence in the performance of its duties under these Master Terms, or by reason of reckless disregard of its obligations and duties under these Master Terms.

(iii) The Servicer, in consideration for continuing to receive the servicing fee shall be liable as primary obligor for, and shall indemnify, defend and hold harmless the Interim Eligible Lender Trustee in its individual capacity and its officers, directors, employees and agents from and against, all costs, expenses, losses, claims, damages, obligations and liabilities arising out of, incurred in connection with or relating to these Master Terms, the other Basic Documents, the acceptance or performance of the trusts and duties set forth herein and in the Sale Agreement or the action or the inaction of the Interim Eligible Lender Trustee hereunder (except in connection with the representations and warranties of the Servicer herein, in respect of which the Servicer shall provide such indemnification), except to the extent that such cost, expense, loss, claim, damage, obligation or liability: (a) shall be due to the willful misfeasance, bad faith or negligence (except for errors in judgment) of the Interim Eligible Lender Trustee, (b) shall arise from any breach by the Interim Eligible Lender Trustee of its covenants in its individual capacity made under any of the Basic Documents; or (c) shall arise from the breach by the Interim Eligible Lender Trustee of any of its representations or warranties made in its individual capacity set forth in these

Master Terms or any Purchase Agreement. In the event of any claim, action or proceeding for which indemnity will be sought pursuant to this paragraph, the Interim Eligible Lender Trustee’s choice of legal counsel shall be subject to the approval of Mustang Funding I and the Servicer, which approval shall not be unreasonably withheld.

Indemnification under this Section 9 shall survive the resignation or removal of the Interim Eligible Lender Trustee, the termination of these Master Terms, and the resignation or removal of the Servicer (unless any successor servicer agrees in writing to assume the obligations of the Servicer under this Section 9) and shall include reasonable fees and expenses of counsel and expenses of litigation. If the Servicer shall have made any indemnity payments pursuant to this Section and the Person to or on behalf of whom such payments are made thereafter shall collect any of such amounts from others, such Person shall promptly repay such amounts to the Servicer, without interest.

SECTION 10. MERGER OR CONSOLIDATION OF, OR ASSUMPTION OF THE OBLIGATIONS OF THE SELLER

Any Person (a) into which Mustang Funding I may be merged or consolidated, (b) which may result from any merger or consolidation to which Mustang Funding I shall be a party or (c) which may succeed to the properties and assets of Mustang Funding I substantially as a whole, shall be the successor to Mustang Funding I without the execution or filing of any document or any further act by any of the parties to these Master Terms; provided, however, that Mustang Funding I hereby covenants that it will not consummate any of the foregoing transactions except upon satisfaction of the following: (i) the surviving Person, if other than Mustang Funding I, executes an agreement of assumption to perform every obligation of Mustang Funding I and the Servicer under these Master Terms, each Purchase Agreement and each Bill of Sale; (ii) immediately after giving effect to such transaction, no representation or warranty made pursuant to Section 5 shall have been breached; (iii) the surviving Person, if other than Mustang Funding I, shall have delivered to the Interim Eligible Lender Trustee an Officers’ Certificate and an Opinion of Counsel each stating that such consolidation, merger or succession and such agreement of assumption comply with this Section and that all conditions precedent, if any, provided for in these Master Terms relating to such transaction have been complied with, and that the Rating Agency Condition shall have been satisfied with respect to such transaction; and (iv) if Mustang Funding I is not the surviving entity, Mustang Funding I shall have delivered to the Interim Eligible Lender Trustee an Opinion of Counsel either (A) stating that, in the opinion of such counsel, all financing statements and continuation statements and amendments thereto have been executed and filed that are necessary fully to preserve and protect the interest of Funding and the Interim Eligible Lender Trustee, respectively, in the Purchased Loans and reciting the details of such filings, or (B) stating that, in the opinion of such counsel, no such action shall be necessary to preserve and protect such interests.

SECTION 11. LIMITATION ON LIABILITY OF MUSTANG FUNDING I AND OTHERS

Mustang Funding I and any director or officer or employee or agent thereof may rely in good faith on the advice of counsel or on any document of any kind, prima facie properly executed and submitted by any Person respecting any matters arising hereunder (provided that such reliance shall not limit in any way Mustang Funding I’s obligations under Section 6). Mustang Funding I’s 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 Mustang Funding I will constitute the sole remedy available to Funding for uncured breaches; provided, however, that the information with respect to the Purchased Loans listed on the related Bill of Sale may be adjusted in the ordinary course of business subsequent to the date of the related Bill of Sale and to the extent that the aggregate Principal Balance of the Purchased Loans listed on the related Bill of Sale is less than the aggregate Principal Balance stated on the related Bill of Sale, Mustang Funding I 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 the Initial Purchase Agreement has been, and any Additional Purchase Agreement will be, signed by The Bank of New York Trust Company, N.A. not in its individual capacity but solely in its capacity as the Mustang Funding I Eligible Lender Trustee for Mustang Funding I and the Interim Eligible Lender Trustee for Funding and in no event shall The Bank of New York Trust Company, N.A. in its individual capacity have any liability for the representations, warranties, covenants, agreements or other obligations of the Mustang Funding I Eligible Lender Trustee, the Interim Eligible Lender Trustee, Mustang Funding I or Funding, under these Master Terms or any Purchase Agreements 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 Mustang Funding I or Funding.

SECTION 13. EXPENSES

Except as otherwise provided herein, each party to these Master Terms or any Purchase Agreement (other than the VG Eligible Lender Trustee and the Interim Eligible Lender Trustee) 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 the Purchase Agreement and each Additional Purchase Agreement executed pursuant to these Master Terms shall survive the consummation of the acquisition of the Purchased Loans provided for in the related Purchase Agreement.

All covenants, agreements, representations and warranties made or furnished pursuant hereto by the Servicer shall bind and inure to the benefit of any successors or assigns of Funding and the Interim Eligible Lender Trustee on behalf of Funding and shall survive with respect to each Purchased Loan.

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 Mustang Funding I or the Servicer 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 Mustang Funding I 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 Mustang Funding I 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.

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, any Purchase Agreement, any Bill of Sale and any document or instrument delivered in accordance herewith or therewith 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 in the related document 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 Indenture Trustee, materially and adversely affect the interest of any such Noteholder.

These Master Terms, any Purchase Agreement and any document or instrument delivered in accordance herewith or therewith may also be amended from time to time by Mustang Funding I, the Mustang Funding I Eligible Lender Trustee, 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 in the related document 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 Purchased 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 (such notice to be prepared by the Administrator) 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 17 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, Mustang Funding I, the Servicer, the Mustang Funding I Eligible Lender Trustee 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 Funding; provided, however, nothing herein shall be deemed to prohibit the Mustang Funding I Eligible Lender Trustee or the Interim Eligible Lender Trustee from filing a claim in, or otherwise participating in, any such action or proceeding.

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.
