All moneys received by the Trustee pursuant to Sections 9.02(d) or (e) of the Indenture, or otherwise from the Issuer, for deposit in the Reserve Fund, together with any Eligible Investments in which such moneys are or will be invested or reinvested during the term of the Indenture, shall be held by the Trustee in the Reserve Fund as part of the Trust Estate granted to secure the Notes, subject to disbursement and withdrawal as herein provided.

(b) So long as no Default or Event of Default shall have occurred and be continuing, all or a portion of any moneys in the Reserve Fund shall be invested and reinvested by the Trustee at the Issuer's written direction in one or more Eligible Investments bearing interest or sold at discount.

All income or other gain from investments of money held in the Reserve Fund shall be deposited by the Trustee in the Reserve Fund promptly upon receipt, and any loss resulting from such investments shall be charged to the Reserve Fund. (c) Unless the Notes have been declared due and payable pursuant to Section 5.02 of the Indenture, on each Payment Date the Trustee shall withdraw from the Reserve Fund in accordance with the Determination Date Statement, and deposit in the Distribution Account an amount equal to the amount, if any, by which the Note Interest Payment for such Payment Date exceeds the amount on deposit in the Distribution Account on such Payment Date that is available for such payment (before giving effect to any withdrawal from the Reserve Fund on such date for deposit in the Distribution Account). (d) On any Redemption Date on which an Optional Redemption has been declared by the Issuer, the Trustee shall upon receipt of an Issuer Order withdraw from the Reserve Fund, to the extent of funds on deposit therein, and deposit in the Distribution Account the amount, if any, by which the Redemption Price exceeds the amount on deposit in the Distribution Account on such Redemption Date that is available for such payment (before giving effect to any withdrawal from the Reserve Fund on such date for deposit in the Distribution Account); provided that on such Redemption Date the full Redemption Price is paid to the Outstanding Noteholders. (e) On the Stated Maturity of the Notes, a Mandatory Redemption Date, a Special Redemption Date or an Optional Redemption Date, the Trustee shall withdraw from the Reserve Fund and deposit in the Distribution Account the amount, if any, by which the Note Payment for such Payment Date exceeds the amount on deposit in the Distribution Account on such Payment Date that is available for such payment (before giving effect to any withdrawal from the Reserve Fund on such date for deposit in the Distribution Account); provided, in the case of Mandatory Redemption or an Optional Redemption, that on such Payment Date the full Redemption Price is paid to the Outstanding Noteholders. Upon the satisfaction and discharge of the Agreement in accordance with Article Four of the Indenture, upon receipt of an Issuer Request, the Trustee shall pay or transfer to the Issuer all money or Eligible Investments then in the Reserve Fund. IV Rights of Series 1997-1 Noteholders and Distribution of Collections Collection and Distribution of Money. (a) The Class A Notes shall bear interest from the Closing Date until paid at the Class A Note Interest Rate. Thirty days of interest shall be due and payable on each Payment Date (other than the first and, if applicable, last Payment Date) on the Note Principal Balance of the Class A Notes, determined as of the Closing Date with respect to the first Payment Date, and thereafter, the preceding Payment Date (after giving effect to any principal payment made on such Notes on such date). Interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months. If the amounts available in the Distribution Account and Reserve Fund are insufficient to pay the amount of interest due and payable on the Class A Notes on any Payment Date, such shortfall will be carried forward and added to the amount due on such Class A Notes on the next Payment Date. Any such amount carried forward will bear interest, to the extent legally permissible, at a rate per annum which shall be equal to 200 basis points in excess of the Class A Note Interest Rate. (a) The principal of the Class A Notes shall be payable commencing on the Amortization Date and on each Payment Date thereafter, to the extent of the amount available after payment of all interest payable on the Notes, to the extent that funds remain in the Collection Account as provided in Section 4.02 hereof. (b) The Class B Notes shall bear interest on the average daily Class B Note Principal Balance for the related Interest Period at the Class B Note Interest Rate. Interest on the Class B Notes shall be payable on each Payment Date for the related Interest Period. Interest will be calculated on the basis of the actual number of days elapsed in the Interest Period and a 360- day year. If the amounts available in the Distribution Account and the Reserve Fund are insufficient to pay the amount of interest due and payable on the Class B Notes on any Payment Date, such shortfall will be carried forward and added to the amount due on such Class B Notes on the next Payment Date. Any such amount carried forward will bear interest, to the extent legally permissible, at a rate per annum which shall be equal to 200 basis points in excess of the Class B Note Interest Rate. (c) The principal of the Class B Notes shall be payable commencing on the Amortization Date and on each Payment Date thereafter, to the extent of the amount available after payment of all interest payable on the Notes, to the extent that funds remain in the Collection Account as provided in Section 4.02 hereof. On any Payment Date during the Non-Amortization Period, the Issuer may designate amounts on deposit in the Collection Account to pay principal in whole or in part of the Class B Notes. (d) Except as otherwise expressly provided herein or in the Indenture, the Trustee may demand payment or delivery of, and shall receive and collect, directly and without intervention or assistance of any fiscal agent or other intermediary, all money and other property payable to or receivable by the Trustee pursuant to the Agreement, including all payments due on account of any of the Receivables pledged to secure the Notes. The Trustee shall hold all such money and property received by it in trust for the Holders of the Notes and shall apply it as provided in the Agreement. Except as otherwise expressly provided in the Agreement, if any Default occurs in the making of any payment or performance under the Servicing Agreement, the Trustee may, and upon the written request of the Required Holders (as evidenced by the Note Register) shall, take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate Proceedings. Any such action shall be without prejudice to any right to claim a Default or Event of Default under the Agreement and to proceed thereafter as provided in Article Six of the Indenture. Distribution Account. (a) Prior to the initial authentication and delivery of the Notes, the Issuer shall open, at a depository institution (which may be the Trustee), an Eligible Account denominated "Distribution Account -- Bankers Trust Company, as trustee in respect of 7.486% Fixed Rate Contract Receivable Collateralized Notes, Series 1997-1, Class A and Floating Rate Contract Receivable Collateralized Notes, Series 1997-1, Class B". The Distribution Account shall be held in the corporate trust department of such depositary institution, in trust and shall relate solely to the Series 1997-1 Notes and Eligible Investments securing the Series 1997-1 Notes. Funds in the Distribution Account shall be held as provided in Section 6.06 of the Indenture. The Issuer shall give the Trustee at least five Business Days' written notice of any change in the location of the Distribution Account and any related account identification information. All payments to be made from time to time to the Holders of Series 1997-1 Notes, out of funds in the Distribution Account pursuant to this Series 1997-1 Supplement shall be made by the Trustee as the Paying Agent of the Issuer or, pursuant to Section 8.10 of the Indenture, by any other Paying Agent appointed by the Issuer. All moneys deposited from time to time in the Distribution Account, including the deposits to be made by the Servicer in the Distribution Account pursuant to the Servicing Agreement, and all investments made with such moneys, shall be held by the Trustee as part of the Trust Estate as herein provided. (b) So long as no Default or Event of Default shall have occurred and be continuing, all or a portion of the Distribution Account shall be invested and reinvested by the Trustee at the Issuer's written direction in one or more Eligible Investments bearing interest or sold at discount. All income or other gain from investment of moneys deposited in the Distribution Account shall be deposited in the Distribution Account immediately upon receipt, and any loss resulting from such investment shall be charged to such Distribution Account. Notwithstanding the definition of "Eligible Investments", in the case of an Account maintained with the Paying Agent, Eligible Investments on which the Paying Agent is the obligor (including repurchase agreements on which the Paying Agent in its commercial capacity is liable as principal), may mature on the Payment Date next succeeding the date of investment. (c) On each Payment Date during the Non-Amortization Period, amounts that have been deposited in the Distribution Account pursuant to Section 9.02(d) of the Indenture will be distributed as follows: first, to the payment of all interest due on the Series 1997-1 Notes and any Commitment Fee due to the Purchaser pursuant to the Class B Note Purchase Agreement; second, to the payment of principal on any Class B Notes as is designated by the Issuer; third, to the payment of all principal due on any Class A Notes that have been called for redemption; and fourth, to the payment of any Yield Maintenance Amount due on any Class A Notes that have been called for redemption. (d) On each Payment Date during the Amortization Period, amounts that have been deposited in the Distribution Account pursuant to Section 9.02(e) of the Indenture will be distributed as follows: first, to the payment of all interest due on the Series 1997-1 Notes; second, to the payment of all principal due on any Series 1997-1 Notes that have been called for redemption to be distributed to the Holders thereof on a pro rata basis; and third, to the payment (or distribution to the Issuer for payment) of the Principal Distribution Amount due on the Series 1997-1 Notes to be distributed to the Holders thereof on a pro rata basis. (e) On any Payment Date if amounts on deposit in the Distribution Account are not sufficient to make any portion of the Note Interest Payment on such Payment Date, an amount equal to the amount by which the amount available in the Distribution Account is less than the Note Interest Payment will be withdrawn from the Reserve Fund in accordance with the Determination Date Statement, to pay, to the extent available, all interest payable on the Series 1997-1 Notes on such Payment Date. General Provisions Regarding Distribution Account and Reserve Fund. (a) The Issuer shall not direct the Trustee to make any investment of any funds in an Account or the Reserve Fund or to sell any investment held in an Account or the Reserve Fund except under the following terms and conditions: (i) (A) each such investment shall be made in the name of the Trustee (in its capacity as such) or its agents, custodians or nominees (or, if, as indicated by an Opinion of Independent Counsel delivered to the Trustee, applicable law provides for perfection of pledges of an investment not evidenced by a certificate or other instrument through registration of such pledge on books maintained by or on behalf of the issuer of such investment, such pledge may be so registered), (B) the Trustee shall have sole investment control over such investment, the income thereon and the proceeds thereof, and (C) any instrument evidencing such investment shall be delivered directly to the Trustee or its agent; and (ii) the proceeds of each such sale of an investment shall be remitted by the purchaser thereof directly to the Trustee for deposit in the Account or the Reserve Fund in which such investment was held. (b) If any amounts are needed for disbursement from an Account or the Reserve Fund and sufficient uninvested funds are not available to make such disbursement, in the absence of an Issuer Order for the liquidation of investments in an amount sufficient to provide the required funds, the Trustee shall cause to be sold or otherwise converted to cash a sufficient amount of the investments in such Account or the Reserve Fund; provided that such investments shall be sold in arm's-length transactions for not less than their fair market value; provided, further, that the Trustee may rely upon the appraisal of an independent appraiser in determining such fair market value. (c) The Trustee shall not in any way be held liable by reason of any insufficiency in any Account or the Reserve Fund resulting from any loss on any Eligible Investment included therein except that the Trustee shall remain liable on Eligible Investments which are obligations of the Trustee in its commercial capacity. (d) All investments of funds in an Account or the Reserve Fund and all sales of Eligible Investments held in an Account or the Reserve Fund shall, except as otherwise expressly provided in the Agreement, be made by the Trustee in accordance with an Issuer Order. Such Issuer Order may prescribe specific actions (including, without limitation, that such funds shall not be invested, in which case such funds shall remain deposited in the Distribution Account or Reserve Fund) or may be a general, standing order authorizing the Trustee to act within certain general parameters or to act on written, facsimile or telephonic instructions (which telephonic instructions shall be confirmed in writing) of specified personnel or agents of the Issuer. In the event that: (i) the Issuer shall have failed to give investment directions to the Trustee by 12:01 p.m. New York time on any Business Day authorizing the Trustee to invest the funds then in an Account or the Reserve Fund, (ii) a Default or Event of Default shall have occurred and be continuing but the Series 1997-1 Notes shall not have been declared due and payable pursuant to Section 5.02 of the Indenture, or (iii) an Event of Default shall have occurred and be continuing, the Series 1997-1 Notes shall have been declared due and payable pursuant to Section 5.02 of the Indenture, and amounts collected or receivable from the related Trust Estate are being applied in accordance with Section 5.06 of the Indenture, the Trustee shall invest and reinvest the funds then in each Account or the Reserve Fund to the fullest extent practicable, but only in one or more Eligible Investments bearing interest or sold at a discount, upon written direction by the Issuer. All investments made pursuant to clause (i) above shall mature on the next Business Day following the date of such investment, all such investments made pursuant to clause (ii) above shall mature no later than the latest maturity date therefor permitted for Eligible Investments, and all investments made pursuant to clause (iii) above shall mature no later than the first date following the date of such investment on which the Trustee proposes to make a distribution to Series 1997-1 Noteholders pursuant to Section 5.06 of the Indenture. Determination of LIBOR. (a) On each LIBOR Determination Date, the Trustee will determine LIBOR on the basis of the rate for deposits in Eurodollars for a one-month period which appears on Telerate Page 3750 as of 11:00 a.m., London time, on such date. If such rate does not appear on Telerate Page 3750, the rate for that LIBOR Determination Date will be determined on the basis of the rates at which deposits in Eurodollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The Trustee will request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date will be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the Issuer, at approximately 11:00 a.m., New York City time, on that day for loans in Eurodollars to leading European banks for a one-month period. (a) On each LIBOR Determination Date, the Trustee shall send to the Issuer, the Servicer and the Purchaser by facsimile, notification of the LIBOR Rate for the following Interest Period. V Redemption of Series 1997-1 Notes Optional Redemption. The Class A Notes will be redeemable in whole on any day on which the Class B Note Principal Balance is equal to zero, at the option of the Issuer, at the Redemption Price for an Optional Redemption; provided, however, that if such day occurs on or after the Amortization Date, the Redemption Price of such Notes shall not include any Yield Maintenance Amount.

If, on any Determination Date, (i) the Collateral Value Ratio as set forth in the Determination Date Statement prepared in accordance with Section 4.02 of the Servicing Agreement is below 1.00 and the Issuer does not substitute Receivables or deposit cash into the Collection Account or reduce the Class B Note Principal Balance such that the Collateral Value Ratio, as set forth in such Determination Date Statement, is raised to 1.00 prior to the related Payment Date and (ii) such ratio was below 1.00 on the previous Determination Date and the Company did not substitute Receivables or deposit cash into the Collection Account or reduce the Class B Note Principal Balance such that the Collateral Value Ratio, as set forth in the Determination Date Statement for such previous Determination Date, was raised to 1.00 prior to the current Determination Date, the Trustee shall promptly give notice that it will redeem a portion of the Series 1997-1 Notes on the next Payment Date. The Trustee shall call for a Special Redemption of the Series 1997-1 Notes in an amount equal to the lesser of (i)(A) the Outstanding Note Principal Balance minus (B) the sum of (1) the aggregate Stated Value of the Receivables, less the aggregate Stated Value of any Excluded Receivables, in each case valued at the applicable Collateral Value Percentage and (2) the amount on deposit in the Collection Account and (ii) the Outstanding Note Principal Balance. The amounts in clauses (A) and (B)(1) above shall be calculated by the Issuer as of the end of the Determination Period preceding such Determination Date. Such redemption will be at the Redemption Price for a Special Redemption. During the period from the Determination Date on which the Trustee gives notice of a Special Redemption until the succeeding Payment Date, subject to Section 4.02(c) hereof and Section 9.02(c) of the Indenture, Collections will be retained in the Collection Account until the amount of funds on deposit therein is equal to the Redemption Price for such Special Redemption. If, after the Payment Date on which a Special Redemption is to be made during the Non-Amortization Period, any portion of the related Redemption Price has not been paid, funds may not be withdrawn from the Collection Account to purchase Eligible Receivables pursuant to Section 4.02(c) hereof until the amount required for such Special Redemption is on deposit in the Collection Account and transferred to the Distribution Account. Any Special Redemption will be paid, to the extent of funds available in the Collection Account and the Distribution Account, first to the payment of all amounts owing on the Class B Notes until the Class B Note Principal Balance is reduced to zero and second to the payment of all amounts owing on the Class A Notes. (b) Mandatory Redemption. The Trustee shall as soon as practicable on any Determination Date promptly give notice of a Mandatory Redemption of all the Outstanding Series 1997-1 Notes, based on information contained in the Determination Date Statement, if: (i) on the preceding Determination Date, the Collateral Value Ratio was determined to be less than or equal to the Mandatory Redemption Level as of the last day of the second preceding Determination Period and the Company has not caused the Collateral Value Ratio to be increased above the Mandatory Redemption Level by substitution of Receivables or depositing cash into the Collection Account or reduction of the Class B Note Principal Balance; (ii) three Special Redemptions (including such current Determination Date) are required within any consecutive 12-month period; or (iii) on any Determination Date, (a) the aggregate Stated Value of all Ineligible Receivables which have been Ineligible Receivables for more than 30 days exceeds 7% of the Aggregate Collateral Balance and (b) the Collateral Value Ratio is less than 1.00. In the case of clause (i) above, the payment of principal pursuant to the Mandatory Redemption will be due on the Payment Date immediately following the Determination Date next succeeding such notice of a Mandatory Redemption, and in the case of clauses (ii) or (iii) above, such payment will be due on the Payment Date next succeeding such notice. Such redemption will be at the Redemption Price for a Mandatory Redemption. Any Mandatory Redemption will be paid, to the extent of funds available in the Collection Account and the Distribution Account, to the Series 1997-1 Noteholders in the proportion that the Note Principal Balance of each Series 1997-1 Note to be redeemed bears to the Outstanding Note Principal Balance; provided that if funds available on such Payment Date in the Collection Account and the Distribution Account are insufficient therefor, payment of a Mandatory Redemption may include funds on deposit in the Reserve Fund; provided, further, that the aggregate of funds available on such Payment Date in the Collection Account, the Distribution Account and the Reserve Fund are sufficient to pay in full the Outstanding Note Principal Balance. (c) Mandatory Redemption upon Direction of Noteholders. If on any date of determination the Issuer is prohibited from purchasing additional Eligible Receivables pursuant to Section 3.03 of the Sale and Purchase Agreements, the Issuer shall give notice thereof to the Series 1997-1 Noteholders, which notice shall reference this Section 5.02(c) relating to Mandatory Redemption. If the Required Holders of the Series 1997-1 Notes so direct the Trustee in writing, the Trustee shall give notice of a Mandatory Redemption of all the Outstanding Series 1997-1 Notes. Payment will be due on the Payment Date next succeeding such direction from the Required Holders of the Series 1997-1 Notes at the Redemption Price for a Mandatory Redemption. Section 5.03. Notice of Optional Redemption by Issuer. The Issuer shall give the Trustee and each Class A Noteholder fifteen Business Days prior written notice of any Optional Redemption. All notices of redemption shall state: (a) the Redemption Date; (b) the Redemption Price (including any Yield Maintenance Amount, if applicable); (c) that interest thereon shall cease to accrue on the date specified on the notice; (d) the place where such Series 1997-1 Notes are to be surrendered (or an indemnity reasonably satisfactory to the Trustee provided) for payment of the Redemption Price, which shall be the office or agency of the Trustee to be maintained as provided herein. Failure to give notice of redemption, or any defect therein, to any Holder of any Series 1997-1 Note selected for redemption shall not impair or affect the validity of the redemption of any other Series 1997-1 Note. Section 5.04. Deposit of Redemption Price for Optional, Special and Mandatory Redemptions. (a) In the case of an Optional Redemption, on or before the Payment Date on which such Optional Redemption is to be made, the Issuer shall deposit in the Distribution Account cash in an amount sufficient to provide for payment of the Redemption Price of all of the Class A Notes (unless such payment is to be made from funds on deposit in the Collection Account, any Lock-box Account or the Reserve Fund). (b) In the case of all Special Redemptions and any Mandatory Redemption, on or before the Payment Date on which a Special Redemption or Mandatory Redemption is to be made, the Issuer shall deposit into the Distribution Account cash in an amount sufficient to provide payment of the Redemption Price for all of the Series 1997-1 Notes that are to be redeemed on such Payment Date. If during the Non-Amortization Period any portion of the amount to be paid on a Payment Date as a Special Redemption or Mandatory Redemption remains outstanding after such Payment Date, cash will not be released from the Collection Account for the purpose of acquiring additional Eligible Receivables or for the payment of the Series 1997-1 Pro Rata Share of the Servicing Fee until such unpaid Special Redemption or Mandatory Redemption Amount is paid or cash therefor is on deposit in the Distribution Account. Any Special Redemption and Mandatory Redemption will be paid to the Series 1997-1 Noteholders in the proportion that the Note Principal Balance of each Series 1997-1 Note to be redeemed bears to the Outstanding Note Principal Balance. Section 5.05. Series 1997-1 Notes Payable on Redemption Date. Notice of redemption having been given as provided in Section 5.03 hereof, the Series 1997-1 Notes or portions thereof so to be redeemed shall, on the applicable Redemption Date, become due and payable at the Redemption Price and on such Redemption Date (unless the Issuer shall Default in the payment of the Redemption Price) such Series 1997-1 Notes (or portion thereof) shall cease to bear interest as specified in the Agreement. On or after the Redemption Date, such Series 1997-1 Notes shall be paid by the Issuer at the Redemption Price; provided, however, that payments due on a Redemption Date which is also a Payment Date shall be payable to the Holders of such Series 1997-1 Notes registered as such on the relevant Record Dates according to their terms. If any Outstanding Series 1997-1 Note called for Optional Redemption pursuant to Section 5.01 hereof shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at a per annum rate equal to 200 basis points in excess of the applicable Note Interest Rate. Section 5.06. Payments Upon Certain Events of Default and Triggers. (a) If an Event of Default specified in clause (1), (2), (8), (9), (10) (as to clause (10), with respect to Sections 5.01(c) and (d) only of the Servicing Agreement) or clauses (3) or (4), to the extent permitted by law, of Section 5.01 of the Indenture occurs, the amounts payable on the Class A Notes pursuant to Section 5.02(b) of the Indenture shall include Yield Maintenance Amount. (b) If (a) at the close of business on the date of any Increase, after giving effect to the Increase and any withdrawals from the Collection Account, the amount on deposit in the Collection Account is in excess of $45,000,000, and (b) the foregoing condition continues for the three Business Days following such date of Increase, then, on the next following Business Day (x) the amount by which the amount on deposit in the Collection Account at the end of the preceding Business Day exceeded the amount of $45,000,000 shall be paid as a reduction in principal of the Class B Notes and (y) the Issuer shall pay a fee of $2,000 to the Class B Noteholders.

This Class A Note is one of a duly authorized issue of Series 1997-1 Notes of the Issuer, designated as the 7.486% Fixed Rate Contract Receivable Collateralized Notes, Series 1997-1, Class A (herein referred to as the "Class A Notes"), limited in aggregate principal amount to $50,000,000 under the Agreement, subject to the terms, provisions and conditions of the Agreement, to which Agreement reference is made for a statement of the respective rights thereunder of the Issuer, the Trustee and the Holders of the Series 1997-1 Notes, and the terms upon which the Series 1997-1 Notes are, and are to be, authenticated and delivered. Also issued under the Agreement are the Floating Rate Contract Receivable Collateralized Notes, Series 1997-1, Class B. A summary of certain of the pertinent provisions of the Agreement is set forth hereinafter. All terms used in this Class A Note that are not otherwise defined herein shall have the meanings assigned to them in the Agreement. Each payment of this Class A Note shall be applied first to the payment of interest accrued and unpaid on this Class A Note and then, if principal is then payable, to the payment of principal of this Class A Note. The interest on this Class A Note and principal of this Class A Note shall be distributable in lawful money of the United States in the following manner: (a) Interest shall be payable on this Class A Note at the rate of 7.486% per annum (the "Class A Note Interest Rate"). Thirty days of interest shall be due and payable on the 30th day of each month or, if such day is not a Business Day, the next succeeding Business Day (each, a "Payment Date") commencing on April 30, 1997 on the Class A Note Principal Balance of the Class A Notes, determined as of the Closing Date with respect to the first Payment Date, and thereafter, the preceding Payment Date (after giving effect to any principal payment made on such Notes on such date). Interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months. If the amounts available in the Distribution Account and the Reserve Fund are insufficient to pay the amount of interest due and payable on the Class A Notes on any Payment Date, such shortfall will be carried forward and added to the amount due on such Class A Notes on the next Payment Date. Any such amount carried forward will bear interest, to the extent legally permissible, at a rate per annum which shall be equal to 200 basis points in excess of the Class A Note Interest Rate. (b) The principal of the Class A Notes shall be payable commencing on the Amortization Date and each Payment Date thereafter and otherwise in accordance with the Agreement, to the extent of the amount available after payment of all interest payable on the Notes, to the extent that funds remain in the Collection Account, as provided in the Agreement. The Holders of the Class A Notes as of the Record Date in respect of a Payment Date shall be entitled to the interest accrued and payable and the principal payable on such Payment Date. Payments of principal to such Holders shall be made in the proportion that the unpaid principal balance of the Class A Notes registered in the name of each such Holder on such Record Date bears to the aggregate unpaid principal balance of all the Class A Notes (the "Outstanding Class A Note Principal Balance") on such Record Date. All payment obligations under a Class A Note are discharged to the extent such payments are made to the Holder of record. The principal and interest to be distributed on any Payment Date will, as provided in the Agreement, be distributed to the Person in whose name this Class A Note is registered on the Record Date for such Payment Date. Payments on the Class A Notes shall be made by the Trustee by wire transfer of immediately available funds to the account of the Person entitled thereto at a bank or other entity having appropriate facilities therefor if such Person shall have so notified the Trustee in writing by the Record Date immediately prior to such Payment Date and is the registered owner of Class A Notes in the initial aggregate principal amount equal to or in excess of $500,000. The final installment of principal of and interest on each Class A Note shall be payable on or before its Class A Stated Maturity. The Trustee shall notify the Person in whose name a Class A Note is registered at the close of business on the twenty-fifth day of the month next preceding the month of the Payment Date on which the Issuer expects that the final installment of principal of and interest on such Class A Note will be paid. Upon payment of the final installment of principal of and interest on each Class A Note, the Holders will return the Class A Notes to the Trustee for cancellation. The Class A Notes may be redeemed, at the option of the Issuer, on notice as provided in the Agreement, in whole but not in part, on any Payment Date at a price (the "Redemption Price") equal to the sum of (i) 100% of the then Outstanding Class A Note Principal Balance, (ii) accrued and unpaid interest to such Payment Date and (iii) the applicable Yield Maintenance Amount, if any. The Class A Notes are additionally subject from time to time to redemption (i) in part, pursuant to a Special Redemption and (ii) in whole but not in part, pursuant to a Mandatory Redemption, respectively, under the limited circumstances set forth in the Agreement. The price to be paid for Class A Notes so redeemed will be equal to the applicable Redemption Price. Upon surrender for registration of transfer of any Class A Note in certificated form at the office or agency of the Issuer to be maintained in the United States of America, the Issuer shall execute, and, upon an Issuer Order, the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Class A Notes of any authorized denominations of a like aggregate principal amount. Prior to due presentment for registration of transfer of any Class A Note, the Issuer, the Trustee and any agent of the Issuer or of the Trustee may treat the Person in whose name any Class A Note is registered as the owner of such Class A Note for the purpose of receiving payments of principal and interest on such Class A Note and for all other purposes whatsoever, (whether or not such Class A Note is overdue), and neither the Issuer, the Trustee nor any agent of the Issuer or the Trustee shall be bound by notice to the contrary. If an Event of Default as defined in the Indenture shall occur and be continuing, the principal of all of the Class A Notes may, and in certain cases shall, become or be declared due and payable in the manner and with the effect provided in the Agreement. The Agreement permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights of the Holders of the Class A Notes under the Agreement at any time by the Issuer and the Trustee with the consent of the Registered Holders of all Series evidencing 66 2/3% of the Outstanding Note Principal Balance as of any date of determination.
