E. Agreements of AMS and the Waiving Parties. AMS and each of the Waiving Parties hereby agree as follows: 3 (1) the reviewing by a third party to be designated by MBIA of all reports required to be prepared by the AMS Parties under the Agreements with such review occurring within a reasonable and mutually agreeable time after the submission of such report; and (2) to execute an agreement among the Waiving Parties and the AMS Parties providing for (i) the holding of the Sallie Mae Export Loans by AMS for the benefit of the Waiving Parties and (ii) the application of any and all proceeds from the Sallie Mae Export Loans (whether attributable to collections thereon, disposition thereof or otherwise) for the benefit of EFG-III and the Indenture Trustee. No waiver by the Waiving Parties provided herein shall remain in effect after the expiration hereof as provided herein and the acceptance of the assignment described in (2) above shall not waive any requirements of the Agreements (including without limitation any requirement of AMS or any seller to repurchase loans) subsequent to such expiration. Upon the expiration of this Waiver, (i) the Waiving Parties shall retain all of the rights and remedies relating to the defaults and events of default (including, without limitation, in the case of MBIA only, the right to accelerate the variable funding note and pursue their rights and remedies under the Agreements and applicable law) and (ii) all defaults and events of default shall be reinstated and shall be in full force and effect, unless otherwise cured. It is expressly agreed by the Waiving Parties that the AMS Parties, EFG Funding LLC, EFG Technologies, Inc. and EFG-II SPC-I, Inc. shall have the ability to cure any and all defaults, events of default, amortization events and master servicer defaults in existence as of the date hereof, regardless of whether the applicable cure period has expired. Notwithstanding anything to the contrary herein, other than as set forth in paragraph D. above, EFG-III in its discretion, in accordance with Section 2.04 of the Indenture, may remove, transfer, and/or substitute student loans. Notwithstanding anything to the contrary herein, the Waiving Parties explicitly do not now waive, nor do they agree that they will waive in the future, any future default or event of default. F. Grant of Security Interest. To the extent not otherwise granted in the Agreements (and with respect to AMS, to the extent the assignment of the student loans referenced in clauses A.(l) and A.(2) of this Waiver were to be held not to constitute a sale), each AMS Party hereby grants to Bank One as Indenture Trustee a security interest in and to, and a first lien upon, all property in clauses A.(l) through A.(4) of this Waiver and any and all proceeds of such property to secure all obligations of each applicable AMS Party under each Agreement. G. Reduction in Amount of Commercial Paper and Variable Funding Note. Each of the AMS Parties hereby agree to cause each of the outstanding amount of commercial paper and the outstanding principal amount of the variable funding note to be reduced to (i) $200,000,000 by December 31, 2003, (ii) $100,000,000 by March 31, 2004 and (iii) $50,000,000 by June 30, 2004. If the AMS Parties shall default on their obligation under clauses (i), (ii) or 4 (iii) in the immediately preceding sentence, and such default shall be continuing for thirty (30) days thereafter, the Waiving Parties and the AMS Parties agree that an "Event of Default" under the Indenture and an "Event of Default" under the Liquidity Agreement shall be deemed to have occurred. H. Modification and Waiver. This Waiver may not be altered, amended, or rescinded, nor may any of its provisions be waived, except by an instrument in writing signed by all parties hereto or, in the case of an asserted waiver, by the party against whom the waiver is sought to be enforced. This Waiver may be executed in any number of counterparts, each of which so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument.
