MORTGAGE LOAN TRUST 1999-2 PAGE 5 - - -------------------------------------------------------------------------------- INTEREST CARRY-FORWARD: (a) If, on any Payment Date, the Available Funds Cap Rate (as defined below) for the related Class of Notes limits the payment of the full interest rate on the related Class, the amount of any such shortfall will be carried forward and be due and payable to the Noteholder of the related Class on the following Payment Date and shall accrue interest at the note interest rate until paid (the "Available Funds Cap Carry Forward Amount") . (b) The payment of this Available Funds Cap Carry Forward Amount would be made in future periods from the excess cash flows. (c) The Note Insurer does not cover the Available Funds Cap Carry Forward Amount. AVAILABLE FUNDS CAP RATE: The Available Funds Cap Rate with respect to each Class of Notes for any payment date is a rate per annum equal to the fraction, expressed as a percentage, the numerator of which is (i) an amount equal to (A) 1/12 of the aggregate scheduled principal balance of the then outstanding Mortgage Loans and REO properties in the related Group times the weighted average of the Expense Adjusted Coupon Rates on the then outstanding Mortgage Loans and REO properties in such Group minus (B) the amount of the Note Insurer premium for such payment date allocable to such Group, and the denominator of which is (ii) an amount equal to (A) the then outstanding aggregate Note Balance multiplied by (B) the actual number of days elapsed in the related interest period divided by 360. Payments received by the Indenture Trustee under the Interest Rate Cap Agreement do not increase the Available Funds Cap Rate. "Note Balance" with respect to a Class will equal as of any Payment Date, the Original Note Balance as of the date of issuance of the Notes less all related Monthly Principal and Excess Cash paid to the respective Noteholders on previous Payment Dates. The Expense Adjusted Coupon Rate on any Mortgage Loan is equal to the then applicable coupon rate minus the sum of (i) the Minimum Spread, (ii) the Servicing Fee Rate, and (iii) the Indenture Trustee Fee. For any Payment Date occurring from the Closing Date through and including the twelfth Payment Date, the Minimum Spread is equal to 0.00% per annum. For any Payment Date occurring after the twelfth Payment Date the Minimum Spread is equal to 0.50% per annum. For any Payment Date for so long as the Servicer is the servicer, the Servicing Fee Rate is equal to 0.44% per annum; PROVIDED, HOWEVER, that the Servicing Fee Rate may increase up to 0.50% per annum if it is necessary to appoint a successor Servicer or a successor Sub-Servicer. PAYMENTS OF PRINCIPAL: On each Payment Date, the Noteholders of a Class of Notes will be entitled to payments of Monthly Principal in reduction of the Note Balance. MONTHLY PRINCIPAL The Monthly Principal with respect to each Class of Notes and for any Payment Date will be equal to the lesser of (a) the excess of related Available Funds over the amounts described in clauses (i), (ii) and (iii) of the definition of Excess Cash below, and (b) the aggregate of all scheduled payments of principal received or advanced with respect to the Mortgage Loans in the related Group and due during the related Due Period and all other amounts collected, received - - -------------------------------------------------------------------------------- FIRST UNION SECURITIES THIS SET OF COMPUTATIONAL MATERIALS SUPERSEDES ANY PREVIOUS COMPUTATIONAL MATERIALS, AND WILL BE SUPERSEDED BY THE INFORMATION IN THE PROSPECTUS SUPPLEMENT.

PAYMENTS OF EXCESS CASH: With respect to each Class of Notes and each Payment Date on which the Overcollateralization Amount for the Notes is less than the Required Overcollateralization Amount for such Payment Date, Excess Cash derived from Available Funds, if any, will be paid on the related Class of Notes in reduction of the Note Balance, up to the amount necessary for the related Overcollateralization Amount to equal the applicable Required Overcollateralization Amount "Excess Cash" with respect to a Group on any Payment Date will be equal to Available Funds for such Group and Payment Date, reduced by the sum of (i) any amounts payable to the Note Insurer for Insured Payments with respect to either Group paid on prior Payment Dates and not yet reimbursed and for any unpaid Note Insurer Premiums for such Group on prior Payment Dates (in each case with interest thereon at the Late Payment Rate as defined and set forth in the Insurance Agreement), (ii) the Note Interest for the related Note and Payment Date (and to the extent not covered by Available Funds for the other Group, such amounts with respect to the other Group), (iii) any amounts payable for any Overcollateralization Deficit for the other Class; and (iv) the Monthly Principal for the related Class and Payment Date. The Insurance Policy does not cover the Available Funds Cap Carry Forward Amount, Prepayment Interest Shortfalls or shortfalls in interest due to the application of the Relief Act; the payment of such amounts may be funded only from (a) any excess interest resulting from the Available Funds Cap Rate being in excess of the applicable Interest Rate on future Payment Dates and (b) any Excess Cash for either Group that would otherwise be paid to the holder(s) of the Residual Interest. Any Excess Cash remaining after making required payments on each Class of Notes and to the Note Insurer on any Payment Date as described herein will be released to the holder(s) of the Residual Interest on such Payment Date, free from the lien of the Indenture. OPTIONAL REDEMPTION: Each Class of Notes may be redeemed, in full but not in part, at the option of the Servicer or the Note Insurer, on or after the Payment Date on which the combined principal balance of the Notes has declined to less than 10% of the outstanding Note Balance as of the Settlement Date. COUPON STEP-UP: If the Class A-1 Notes are not redeemed pursuant to the Optional Redemption, the coupon on the Notes will be set at the lesser of (a) one month LIBOR plus [xx] basis points and (b) the related Available Funds Cap Rate. If the Class A-2 Notes are not redeemed pursuant to the Optional Redemption, the coupon on the Notes will be set at the lesser of (a) one month LIBOR plus [xx] basis points and (b) the related Available Funds Cap Rate. INTEREST PERIOD: Interest will accrue on each of the Notes from each Payment Date to and including the day preceding the next Payment Date.

MORTGAGE LOAN TRUST 1999-2 PAGE 7 - - -------------------------------------------------------------------------------- interest will accrue from and including the closing date to, but not including the first Payment Date. COMPENSATING INTEREST PAYMENTS: With respect to any Mortgage Loan in each Group as to which a prepayment in whole or in part was received during the related Collection Period, the Servicer will be required to remit to the Indenture Trustee, up to the amount otherwise payable to the Servicer as its servicing compensation for the related Payment Date, an amount generally calculated to cover Prepayment Interest Shortfalls to ensure that a full month's interest on each such Mortgage Loan is available for payment to the related Noteholders on the applicable Payment Date. Compensating Interest Payments are not reimbursable to the Servicer. The Note Insurer is not required to cover any Prepayment Interest Shortfalls. LEGAL INVESTMENT CONSIDERATIONS: The Notes are SMMEA eligible securities. ERISA CONSIDERATIONS: The Issuer believes that the Notes are ERISA eligible, subject to individual Plan account restrictions. Accordingly, any Plan fiduciary considering whether to purchase any Notes on behalf of a Plan should consult with its counsel prior to purchase of such Notes. TAXATION: The Notes will be treated as debt obligations of the Issuer. No REMIC election will be made.
