All other Bonds that are authenticated after the Delivery Date for any other purpose under the Indenture shall be dated the date of their authentication. Section 4 Book-Entry and Certificated Bonds (a) The Bonds shall be issuable initially as Book-Entry Bonds as one or more certificates in the name of the Clearing Agency or its nominee. For all purposes, the Trustee shall deal with the Clearing Agency as the owner of such Book-Entry Bonds in accordance with Section 3.08 of the Original Indenture. The rights of Beneficial Owners of the Book-Entry Bonds shall be limited to those established by law and agreements between such Beneficial Owners and the Clearing Agency and Clearing Agency Participants. The Beneficial Owners of the Book-Entry Bonds shall not be entitled to certificated securities for the Book-Entry Bonds as to which they are the Beneficial Owners, except as provided below. Requests and directions from, and votes of, the Clearing Agency, as Holder, shall not be deemed to be inconsistent if they are made with respect to different Beneficial Owners. Without the consent of the Issuer and the Trustee, a Book-Entry Bond may not be transferred by the Clearing Agency except to another Clearing Agency that agrees to hold the Book-Entry Bond for the account of the respective Clearing Agency Participants and Beneficial Owners. None of the Issuer, the Bond Administrator, any Master Servicer or the Trustee will have any liability for any aspect of the records relating to or payment made on account of Beneficial Owners of the Book-Entry Bonds held by the Clearing Agency, or for maintaining, supervising or reviewing any records relating to such Beneficial Owners. The Book-Entry Bonds will be issued in fully registered, certificated form to Beneficial Owners of Book-Entry Bonds or their nominees, rather than to the Clearing Agency or its nominee, only if (i) the Issuer advises the Trustee in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities as depository with respect to the Book-Entry Bonds and the Issuer is unable to locate a qualified successor within 30 days, (ii) the Issuer, at its option, elects to terminate the book-entry system operating through the Clearing Agency or (iii) a Private Bond is transferred to an Institutional Accredited Investor. Upon the occurrence of either event described in Clause (i) or Clause (ii) of the immediately preceding paragraph, the Trustee is required to notify the Clearing Agency, which in turn will notify all Beneficial Owners of Book-Entry Bonds through Clearing Agency Participants, of the availability of Certificated Bonds. Upon surrender by the Clearing Agency of the certificates representing the Book-Entry Bonds and receipt of instructions for re-registration, the Trustee will reissue the Book-Entry Bonds as Certificated Bonds to the Beneficial Owners identified in writing by the Clearing Agency. Such Certificated Bonds shall not constitute Book-Entry Bonds. (b) (i) The Private Bonds have not been registered under the Securities Act of 1933, as amended (the "Securities Act") or any state securities or "blue sky" laws, and neither the Issuer nor any other person is under any obligation to register or qualify the Private Bonds under the Securities Act or any state securities or "blue sky" laws or to provide registration rights to any purchaser. No sale, pledge or other transfer of any Private Bond or any beneficial interest therein may be made by any person unless such sale, pledge or other transfer is made (i) to the Issuer or the Initial Purchaser (or a designee of the Initial Purchaser), (ii) pursuant to an effective registration statement under the Securities Act and effective registration or qualification under applicable state securities laws or (iii) (A) to QIBs in transactions complying with the requirements of Rule 144A or (B) to Institutional Accredited Investors who sign a representation letter substantially in the form of Annex A hereto. 12 (ii) No transfer of a Private Bond that is a Certificated Bond ("Certificated Private Bond") may be made to any person unless such person delivers to the Trustee a representation letter in the form attached as Annex A or Annex B hereto as applicable. Each person who becomes a Beneficial Owner of Private Bonds that are Book-Entry Bonds ("Book-Entry Private Bonds") will be deemed to make the representations set forth in Annex C hereto with respect to such acquisition. A QIB may request that Book-Entry Private Bonds of which it is the Beneficial Owner be exchanged for Certificated Private Bonds. Such request must be accompanied with a completed representation letter in the form attached hereto as Annex B. (c) If a Beneficial Owner of a Book-Entry Private Bond proposes to transfer its beneficial interest in such Bond and the proposed transferee is an Institutional Accredited Investor, then the proposed transferee shall deliver an executed representation letter in the form of Exhibit B hereto to the Trustee no later than 30 days prior to the date on which the transfer is to be effectuated and reflected in the Bond Register. The Issuer will cause a Private Certificated Bond to be prepared for execution and delivery, and the Trustee shall authenticate such Private Bond in accordance with the Indenture. Subject to the Clearing Agency's customary procedures, the Beneficial Owner's interest in such Bond held by its Clearing Agency Participant and by the Clearing Agency will be reduced in an amount equal to the aggregate principal amount of the Private Bond being transferred (and the Book-Entry Bond held on behalf of the Clearing Agency will be modified or substituted for accordingly) and a Private Certificated Bond in an equal aggregate principal amount registered in the name of such Institutional Accredited Investor shall be delivered to such Institution Accredited Investor. Thereafter, such Institution Accredited Investor shall be recognized as a Bondholder under the Indenture. In all cases, Private Certificated Bonds delivered in exchange for any beneficial interest in Book-Entry Private Bonds will be registered in the names, and issued in any approved denominations requested by the Beneficial Owner of a Book-Entry Private Bond. (d) If a Holder of a Private Certificated Bond wishes to transfer such Private Bond and the proposed transferee is a QIB that wishes to hold such Bond through the Clearing Agency, then, upon written request of such Bondholder 30 days in advance, subject to the rules and procedures of the Clearing Agency, the Trustee shall arrange for such Private Bond to be represented by a Book-Entry Private Bond registered in the name of the nominee of the Clearing Agency subject to the Clearing Agency recognizing that the Clearing Agency Participant designated by the QIB is the Beneficial Owner of such Book-Entry Bond. Section 5 Denominations The Bonds will be issuable in minimum denominations of $100,000 and increments of $1,000 in excess thereof, except that one Bond of each Class may be issued in a different denomination. Section 6 Determination of Interest Payments (a) Each Class of Bonds will be entitled to receive on each Payment Date an amount equal to the Current Interest and, in the case of the Public Bonds, the Interest Carryover Amount for such Class for such Payment Date. (b) One-Month LIBOR shall be determined as follows: On each Floating Rate Determination Date, the Bond Administrator will determine the arithmetic mean of the London Interbank Offered Rate ("LIBOR") quotations for one-month Eurodollar deposits ("One-Month LIBOR") for the succeeding Accrual Period on the basis of the offered LIBOR quotations provided to the Bond Administrator as of 11:00 a.m. (London time) on such Floating Rate Determination Date. As used herein with respect to a Floating Rate Determination Date, "Reference Banks" means four leading banks engaged in transactions in Eurodollar deposits in the International Eurocurrency market (i) with an established place of business in London, (ii) whose quotations appear on the Bloomberg Screen LIUS01M Index Page on the Floating Rate Determination Date in question and (iii) which have been designated as such by the Bond Administrator and are able and willing to provide such quotations to the Bond Administrator on each Floating Rate Determination Date; and "Bloomberg Screen LIUS01M Index Page" means the display designated as page "LIUS01M" on the Bloomberg Financial Markets Commodities News (or such other pages as may replace such page on that service for the purpose of displaying LIBOR quotations of major banks). If any Reference Bank should be removed from the Bloomberg Screen LIUS01M Index Page or in any other way fails to meet the qualifications of a Reference Bank, the Bond Administrator may, in its sole discretion, designate an alternative Reference Bank. On each Floating Rate Determination Date, One-Month LIBOR for the next succeeding Accrual Period will be established by the Bond Administrator as follows: 13 (i) If on any Floating Rate Determination Date two or more of the Reference Banks provide offered One-Month LIBOR quotations on the Bloomberg Screen LIUS01M Index Page, One-Month LIBOR for the next Accrual Period will be the arithmetic mean of such offered quotations (rounding such arithmetic mean if necessary to the nearest five decimal places). (ii) If on any Floating Rate Determination Date only one or none of the Reference Banks provides such offered quotations, One-Month LIBOR for the next Accrual Period will be the higher of (x) One-Month LIBOR as determined on the previous Floating Rate Determination Date and (y) the Reserve Interest Rate. The "Reserve Interest Rate" will be the rate per annum that the Bond Administrator determines to be either (A) the arithmetic mean (rounding such arithmetic mean if necessary to the nearest five decimal places) of the one-month Eurodollar lending rate that New York City banks selected by the Bond Administrator are quoting, on the relevant Floating Rate Determination Date, to the principal London offices of at least two leading banks in the London interbank market or (B) in the event that the Bond Administrator can determine no such arithmetic mean, the lowest one-month Eurodollar lending rate that the New York City banks selected by the Bond Administrator are quoting on such Floating Rate Determination Date to leading European banks. (iii) If on any Floating Rate Determination Date the Bond Administrator is required but is unable to determine the Reserve Interest Rate in the manner provided in paragraph (ii) above, One-Month LIBOR for the next applicable Accrual Period will be One-Month LIBOR as determined on the previous Floating Rate Determination Date. Notwithstanding the foregoing, One-Month LIBOR for the next succeeding Accrual Period shall not be based on One-Month LIBOR for the previous Accrual Period for two consecutive Floating Rate Determination Dates. If, under the priorities described above, One-Month LIBOR for the next succeeding Accrual Period would be based on One-Month LIBOR for the previous Floating Rate Determination Date for the second consecutive Floating Rate Determination Date, the Bond Administrator shall select an alternative index (over which the Bond Administrator has no control) used for determining one-month Eurodollar lending rates that is calculated and published (or otherwise made available) by an independent third party. The establishment of One-Month LIBOR (or an alternative index) by the Bond Administrator and the Bond Administrator's subsequent calculation of the applicable Class Interest Rates for the relevant Accrual Period, in the absence of manifest error, will be final and binding. (c) The "Fed Funds Rate" with respect to a Fed Funds Business Day means (in the following order of priority): (i) the rate (expressed as a percentage per annum rounded to five decimal places) that appears opposite the caption "Federal Funds Effective Rate" on Telerate Page 120 as of 11:00 a.m., New York City time, on such Fed Funds Business Day; (ii) if such rate does not appear on Telerate Page 120 as of 11:00 a.m., New York City time, on such Fed Funds Business Day, then the Fed Funds Rate with respect to such Fed Funds Business Day will be the rate (expressed as a percentage per annum rounded to five decimal places) that appears on the Reuters Screen NYAA as of 11:00 a.m., New York City time, on such Fed Funds Business Day; (iii) if such rate does not appear on Reuters Screen NYAA as of 11:00 a.m., New York City time, on such Fed Funds Business Day, the Bond Administrator will request three leading brokers of Federal Funds transactions in New York City to provide the rate (expressed as a percentage per annum) for the last transaction in overnight Federal Funds arranged by such broker on such Fed Funds Business Day. If rates are provided by such three brokers, then the Fed Funds Rate with respect to such Fed Funds Business Day will be the arithmetic mean (rounded to the nearest one hundred-thousandth of one percentage point) of such rates; and (iv) if fewer than three such rates are provided, then the Fed Funds rare with respect to such Fed Funds Business Day will be the Fed Funds Rate for the preceding Fed Funds Business Day (or, in the case of the first Fed Funds Business Day, the immediately preceding Fed Business Day on which a rate appeared on Telerate Page 120 as described in (a) above). 14 If a rate that initially appears on Telerate Page 120 or the Reuters Screen NYAA, as the case may be, as of 11:00 a.m., New York City time, on the applicable Fed Funds Business Day is superseded on Telerate Page 120 or the Reuters Screen NYAA, as the case may be, by a corrected rate before 12:00 noon, New York City time, on such Fed Funds Business Day, such corrected rate as so superseded on the applicable page shall be the applicable rate for calculating the applicable Fed Funds Rate for such Fed Funds Business Day. The establishment of the Fed Funds Average Rate by the Bond Administrator and the Bond Administrator's subsequent calculation of the Class Interest Rate for the relevant Accrual Period, in the absence of manifest error, will be final and binding. Section 7 Application of Funds (a) On each Payment Date, the Interest Payment Amount for the Public Bonds will be applied in the following order of priority: First, to pay Current Interest and any Interest Carryover Amount with respect to the Senior Public Bonds; provided, however, that, if the Interest Payment Amount for the Public Bonds is not sufficient to pay the full amount of Current Interest and any Interest Carryover Amount on the Senior Public Bonds, the Interest Payment Amount for the Public Bonds will be applied pro rata based on Current Interest and any Interest Carryover Amount otherwise payable with respect to the Senior Public Bonds; Second, to pay Current Interest and any Interest Carryover Amount with respect to the Class B-1 Bonds; Third, to pay Current Interest and any Interest Carryover Amount with respect to the Class B-2 Bonds; Fourth, to pay Current Interest and any Interest Carryover Amount with respect to the Class B-3 Bonds; Fifth, to pay any unpaid Servicing Fee with respect to the Loans represented by the Class B Certificate; Sixth, to be included in the Group I Principal Payment Amount, Group II Principal Payment Amount and Group III Principal Payment Amount, pro rata, to the extent necessary to cause the Overcollateralization Amount for the Public Bonds to be not less than the product of 3.25% and the Principal Amount of the Public Bonds; and Seventh, any remainder to be deposited in the Surplus Account; (b) On each Payment Date, the Interest Payment Amount for the Private Bonds will be applied in the following order of priority: First, to pay Current Interest with respect to the Senior Private Bonds; provided, however, if the Interest Payment Amount for the Private Bonds is not sufficient to pay the full amount of Current Interest on the Senior Private Bonds, the Interest Payment Amount for the Private Bonds will be applied, pro rata, based on Current Interest payable with respect to the Senior Private Bonds; Second, to pay Current Interest with respect to the Class B-B Bonds; Third, to pay Current Interest with respect to the Class B-C Bonds; Fourth, to pay Current Interest with respect to the Class B-D Bonds; and Fifth, any remainder to be applied in accordance with Section 7(f) hereof. (c) On each Payment Date, the Group I Principal Payment Amount will be applied in the following order of priority: First, to pay principal of the Class 1-A1 and Class 1-A2 Bonds until paid in full, such principal to be paid sequentially in that order such that no such payment will be made to the Class 1-A2 Bonds until the Class 1-A1 Bonds are paid in full; provided, however, that, on any Payment Date on which the aggregate principal balance of the Senior Public Bonds is equal to or greater than the sum of (i) the Aggregate Principal Balance of the Public Bonds Collateral and (ii) the amount in the Collateralization Fund, the Group I Principal Payment Amount will be paid, pro rata, to all the Senior Public Bonds (based on principal balances) and not sequentially; 15 Second, to pay principal of the Class 2-A1, Class 2-A2 and Class 2-A3 Bonds (on the same basis as the Group II Principal Payment Amount is applied to pay such Bonds) and the Class 3-A1 Bonds, pro rata, to the extent required to cause the Senior Public Overcollateralization Test to be met; Third, to pay principal of the Class B-1 Bonds until paid in full; Fourth, to pay principal of the Class B-2 Bonds until paid in full; Fifth, to pay principal of the Class B-3 Bonds until paid in full; and Sixth, any remainder to be deposited in the Surplus Account. (d) On each Payment Date, the Group II Principal Payment Amount will be applied in the following order or priority: First, to pay principal of the Class 2-A1, Class 2-A2 and Class 2-A3 Bonds until paid in full, such principal to be paid sequentially in that order so that no such payment will be made to the Class 2-A2 Bonds until the Class 2-A1 Bonds are paid in full and no such payment will be made to the Class 2-A3 Bonds until the Class 2-A2 Bonds are paid in full; provided, however, that, on any Payment Date on which the aggregate principal balance of the Senior Public Bonds is equal to or greater than the sum of (i) the Aggregate Principal Balance of the Public Bonds Collateral and (ii) the amount in the Collateralization Fund, the Group II Principal Payment Amount will be paid, pro rata, to all the Senior Public Bonds (based on principal balances) and not sequentially; Second, to pay principal of the Class 1-A1 and Class 1-A2 (on the same basis as the Group I Principal Payment Amount is applied to pay such Bonds) and the Class 3-A1 Bonds, pro rata, to the extent required to cause the Senior Public Overcollateralization Test to be met; Third, to pay principal of the Class B-1 Bonds until paid in full; Fourth, to pay principal of the Class B-2 Bonds until paid in full; Fifth, to pay principal of the Class B-3 Bonds until paid in full; and Sixth, any remainder to be deposited in the Surplus Account. (e) On each Payment Date, the product of the Group III Principal Payment Amount will be applied in the following order or priority: First, to pay principal of the Class 3-A1 Bonds until paid in full; provided, however, that, on any Payment Date on which the aggregate principal balance of the Senior Public Bonds is equal to or greater than the sum of (i) the Aggregate Principal Balance of the Public Bonds Collateral and (ii) the amount in the Collateralization Fund, the Group II Principal Payment Amount will be paid, pro rata, to all the Senior Public Bonds (based on principal balances) and not sequentially; Second, to pay principal of the Class 1-A1 and Class 1-A2 Bonds (on the same basis as the Group I Principal Payment Amount is applied to pay such Bonds) and the Class 2-A1, Class 2-A2 and Class 2-A3 Bonds (on the same basis as the Group II Principal Payment Amount is applied to pay such Bonds), pro rata, to the extent required to cause the Senior Public Overcollateralization Test to be met; Third, to pay principal of the Class B-1 Bonds until paid in full; Fourth, to pay principal of the Class B-2 Bonds until paid in full; Fifth, to pay principal of the Class B-3 Bonds until paid in full; and Sixth, any remainder to be deposited in the Surplus Account.

(g) All payments made with respect to each Class of Bonds on each Payment Date shall be allocated, pro rata, among the Bonds of such Class in the proportion that the principal balance of each Bond of such Class bears to the aggregate principal balance of all Bonds of such Class. All payments or allocations of amounts in a Collateral Proceeds Account, the Collateralization Fund and the Surplus Account and all payments made by the Trustee under any section hereof or under the Original Indenture shall be made in accordance with written instructions of the Bond Administrator. (h) On the Delivery Date, the Issuer will establish a fund (the "Collateralization Fund") with the Trustee and deposit therein the Class F Certificate and any payments thereon for the benefit of the Public Bonds. On each Payment Date, the Trustee is required, based on written information provided to the Trustee by the Bond Administrator at least two Business Days prior to such Payment Date: (a) to apply interest earnings on the Class F Certificate and other amounts in the Collateralization Fund to pay interest on the Public Bonds if the portion of the Public Bonds Available Funds attributable to interest is less than the sum of the Current Interest and any Interest Carryover Amounts on all Classes of the Public Bonds; (b) to apply amounts in the Collateralization Fund to pay principal of the Public Bonds in an amount equal to any Realized Losses with respect to the Class A Certificate, the Mortgage Certificates and the Class B Certificate not theretofore covered by such principal payments (so long as the related Senior Public Bonds are Outstanding, any such principal payment with respect to the Class A Certificate shall be applied on the same basis as the Group I Principal Payment Amount, any such principal payment with respect to a Mortgage Certificate shall be applied on the same basis as the Group II Principal Payment Amount and any such principal payment with respect to a Class B Certificate shall be applied on the same basis as the Group III Principal Payment Amount); and (c) to release from the Collateralization Fund to the Surplus Account: (i) any interest earnings not required to be applied as set forth in clause (a) above and (ii) the amount, if any, by which the excess of (x) the sum of (A) the Aggregate Principal Balance of the Public Bonds Collateral and (B) the balance in the Collateralization Fund over (y) the principal balance of the Public Bonds exceeds the Target Public Overcollateralization Amount (calculated after all payments have been made on the Public Bonds for such Payment Date). (i) Any portion of the Public Bonds Available Amount not required to be applied on a Payment Date to pay interest on or principal of the Public Bonds will be deposited in the Surplus Account to be applied in accordance with Sections 7(b) and 7(f) hereof. Any amount in the Surplus Account not required to be applied on a Payment Date to pay interest on or principal of the Private Bonds will be released to the Issuer and will no longer be subject to the lien of the Indenture. Section 8 Places for Payment Payments to the Holders of each Class of Bonds on any Payment Date will be made to the Holders of record of the respective Class on the related Record Date. Payments on the Book-Entry Bonds shall be made to the Clearing Agency by wire transfer. Payments on Certificated Bonds shall be made in accordance with Section 3.07 of the Original Indenture; provided that, at the request of the registered Holder of a Certificated Bond with an original principal balance of $1,000,000 or more, the Trustee shall make payments by wire transfer of immediately available funds if such request is received in writing prior to the Record Date for the related Payment Date. The Trustee may charge any Holder of a Certificated Bond its standard wire transfer fee for any payments made by wire transfer. Section 9 Redemption (a) The Issuer may, at its option, redeem any Class of Public Bonds, in whole, but not in part, on any Payment Date on or after the earlier of (i) May 28, 2005, and (ii) the Payment Date on which, after taking into account payments of principal to be made on such Payment Date, the aggregate principal balance of the Public Bonds is less than 35% of the aggregate principal balance of the Public Bonds issued on the Delivery Date; provided, however, the Collateral securing the Public Bonds shall be pledged to secure the Private Bonds upon the redemption of all the Public Bonds (except that the foregoing shall not apply if the Issuer causes an Affiliate to redeem Public Bonds so that one or more Classes of Public Bonds remain Outstanding for purposes of the Indenture). (b) The Issuer may, at its option, redeem any Class of Private Bonds (other than the Class B-A-1 Bonds), in whole, but not in part, on any Payment Date on or after the earlier of (i) May 28, 2000, (ii) the Payment Date on which, after taking into account payments of principal to be made on such Payment Date, the aggregate principal balance of the Private Bonds is less than 35% of the aggregate principal balance of the Private Bonds issued on the 17 Delivery Date and (iii) the date on which the Public Bonds are redeemed in full. The Issuer may, at its option, redeem the Class B-A-1 Bonds, in whole, but not in part, on any Payment Date on which, after taking into account payments of principal to be made on such Payment Date, the aggregate principal balance of the Class B-A-1 Bonds is less than 10% of the aggregate principal balance of the Class B-A-1 Bonds issued on the Delivery Date. (c) In addition, the Issuer may redeem a Class or Classes of Bonds in whole, but not in part, at any time upon a determination by the Issuer, based upon an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Estate, that a substantial risk exists that Bonds of the Class to be redeemed will not be treated for federal income tax purposes as evidences of indebtedness. Until each Class of Bonds is retired, any optional redemption of a Class of Bonds shall be treated as a purchase of such Bonds, with the result that there will be no acceleration of principal payments on any Class of Bonds not redeemed.
