ACE SECURITIES CORP. DEUTSCHE BANC ALEX. BROWN@ HOME EQUITY LOAN TRUST, SERIES 2001-HE1 - -------------------------------------------------------------------------------- OVERCOLLATERALIZATION: Overcollateralization refers to the amount by which the aggregate principal balance of the Mortgage Loans exceeds the certificate principal balance of the certificates. This excess (the "Overcollateralization Amount") is intended to protect the certificate holders against shortfalls in payments on the certificates. The required Overcollateralization Amount for the Certificates, which will be fully established at issuance, is anticipated to be [0.50]% of the original pool balance. If, due to losses, the Overcollateralization Amount is reduced below [0.50]%, excess spread, if any is available, will be applied to first pay Class A principal, and then Class M principal, in order to maintain the required Overcollateralization Amount. OVERCOLLATERALIZATION After the Stepdown Date, the overcollateralization amount will be allowed to be reduced to STEPDOWN: [1.00]% of the then current balance of the mortgage pool, subject to a floor of $[3,695,698], but only in the event that a Trigger Event has not occurred. OVERCOLLATERALIZATION INCREASE On any Distribution Date, any amount of Net Monthly Excess Cashflow actually applied as an AMOUNT: accelerated payment of principal to the extent the required Overcollateralization Amount exceeds the current Overcollateralization Amount. OVERCOLLATERALIZATION With respect to each such Distribution Date, the Group I Principal Distribution Amount and REDUCTION AMOUNT: the Group II Principal Distribution Amount will each be reduced by an allocated portion of the amount by which the current Overcollateralization Amount exceeds the required Overcollateralization Amount INITIAL CREDIT ENHANCEMENT The Credit Enhancement Percentage for any class and any Distribution Date is the percentage PERCENTAGE: obtained by dividing (x) the aggregate Certificate Principal Balance of the class or classes subordinate thereto by (y) the aggregate principal balance of the Mortgage Loans, calculated after taking into account distributions of principal on the Mortgage Loans and distribution of the Principal Distribution Amount to the holders of the certificates then entitled to distributions of principal on the Distribution Date. INITIAL ENHANCEMENT PERCENTAGE CLASS RATING PERCENT ----- ------ ------- A-1, A-2, A-IO Aaa / AAA / AAA [6.00]% M-1 Aa2 / AA / AA [3.00]% M-2 A2 / A / A [1.50]% M-3 Baa2 / BBB / BBB [0.50]% BASIS RISK SHORTFALL: Because the mortgage rates are either fixed rate, based on 6 month LIBOR, or based on 1 year CMT, and some loans may have delayed first adjustments, and the pass-through rates on the Offered Certificates are based on one month LIBOR, the limitations of the Net WAC Pass-Through Rate could result in shortfalls of interest otherwise payable to the Offered Certificates in certain periods. This may also occur if 6 month LIBOR and 1 month LIBOR rise quickly since the Mortgage Pool cash flows are constrained by interim caps. If basis risk interest shortfalls occur, they will be carried forward at their applicable rate and such shortfalls will be paid on a subordinated basis on the same Distribution Date or in any subsequent period. Such shortfalls will accrue interest at the related pass-through rate. STEPDOWN DATE: Is the earlier of (i) the first Distribution Date on which the Certificate Principal Balances of the Class A Certificates have been reduced to zero and (ii) the later to occur of (x) the Distribution Date occurring in December 2004 and (y) the first Distribution Date on which the Credit Enhancement Percentage (calculated for this purpose only after taking into account distributions of principal on the Mortgage Loans, but prior to any distribution of the Principal Distribution Amount to the holders of the Certificates then entitled to distributions of principal on such Distribution Date) is greater than or equal to approximately [12.00]%.
