Transaction Overview (Cont.)

Record Date:	For so long as the Offered Certificates are held in book-entry form, the Record Date will be the business day immediately preceding the related Distribution Date. With respect to any Offered Certificates held in definitive form, the Record Date will be the last business day of the month immediately preceding the month in which the related Distribution Date occurs.

Distribution Dvbate:	25^th day of each month (or the next business day if such day is not a business day) commencing in March 2007.

Determination Date:	The Determination Date with respect to any Distribution Date and (i) Ocwen, is the business day immediately preceding the related Servicer Remittance Date and (ii) Countrywide, the 18^th day of the month in which the Distribution Date occurs or, if such day is not a business day, on the immediately preceding business day.

Servicer Remittance Date:	With respect to any Distribution Date and (i) Ocwen, the 22nd day of the month in which such Distribution Date occurs; provided that if the 22nd day of a given month is a Saturday, the Servicer Remittance Date shall be the immediately preceding business day and if the 22nd day of a given month is a Sunday or otherwise not a business day (except for Saturdays), the Servicer Remittance Date shall be the next business day, and (ii) Countrywide the 22nd day of the month in which such Distribution Date occurs; provided that if such 22nd day of a given month is not a business day, the Servicer Remittance Date for such month shall be the business day immediately preceding such 22nd day; provided further, that if the Servicer Remittance Date falls on a Friday, the Servicer Remittance Date shall be the business day immediately preceding such Friday.

Due Period:	The Due Period with respect to any Distribution Date commences on the second day of the month immediately preceding the month in which such Distribution Date occurs and ends on the first day of the month in which such Distribution Date occurs.

Prepayment Period:	The Prepayment Period with respect to any Distribution Date and (i) Ocwen, shall be (a) with respect to principal prepayments in full, the period from the 16th day of the month immediately preceding the Distribution Date to the 15th day of the month of the Distribution Date and (b) with respect to principal prepayments in part, the calendar month immediately preceding the month in which the Distribution Date occurs, and (ii) Countrywide, shall be the period from the 16th day of the month immediately preceding the Distribution Date (or with respect to the first Prepayment Period, the period from the Cut-off Date) to the 15th day of the month of the Distribution Date.

Interest Accrual Period:	Interest will initially accrue on the Offered Certificates from the Closing Date to (but excluding) the first Distribution Date, and thereafter, from the prior Distribution Date to (but excluding) the current Distribution Date on an actual/360 basis. The Offered Certificates will initially settle flat (no accrued interest).

Interest Distribution Amount:	For the certificates of any class on any Distribution Date is equal to interest accrued during the related Interest Accrual Period on the certificate principal balance of that class immediately prior to such Distribution Date at the then applicable pass-through rate for such class, and reduced (to not less than zero), in the case of each such class, by the allocable share, if any, for such class of prepayment interest shortfalls to the extent not covered by Compensating Interest paid by the Master Servicer or the Servicers and shortfalls resulting from the application of the Servicemembers’ Civil Relief Act or similar state or local laws.

Senior Interest Distribution Amount:	For the Class A Certificates on any Distribution Date is an amount equal to the sum of the Interest Distribution Amount for such Distribution Date for each such class and the Interest Carry Forward Amount, if any, for such Distribution Date for each such class.

Administration Fee Rate:	The Master Servicer, Servicers and Credit Risk Manager will be paid monthly fees on the outstanding principal balance of the Mortgage Loans. These fees initially aggregate to a weighted average cost of approximately 0.5175% for the Mortgage Loans.

Compensating Interest:	Each Servicer will be required to cover Prepayment Interest Shortfalls on prepayments in full on the Mortgage Loans serviced by such Servicer up to the Servicing Fee payable to each Servicer. If any Servicer fails to make any required Compensating Interest payment, the Master Servicer will be required to do so up to the Master Servicing Fee.


ACE Securities Corp. Home Equity Loan Trust, Series 2007-HE2

Transaction Overview (Cont.)

Prepayment Interest Shortfalls:	Interest shortfalls attributable to voluntary principal prepayments on the Mortgage Loans.

Optional Termination:	On any Distribution Date on which the aggregate outstanding principal balance of the Mortgage Loans as of the last day of the related Due Period is less than or equal to 10% of the aggregate outstanding principal balance of the Mortgage Loans as of the Cut-off Date, the Master Servicer may repurchase all of the Mortgage Loans and REO properties remaining in the trust, causing an early retirement of the certificates, but is not required to do so.

Monthly Servicer Advances:	Each Servicer will collect monthly payments of principal and interest on the Mortgage Loans serviced by such Servicer and will be obligated to make advances of delinquent monthly principal and interest payments. Each Servicer is required to advance delinquent payments of principal and interest on the Mortgage Loans serviced by such Servicer only to the extent such amounts are deemed recoverable. If any Servicer fails to make any such advance, a successor servicer (which may be the Master Servicer) will be required to do so subject to its determination of recoverability. The Servicers and the successor servicer are entitled to be reimbursed for these advances, and therefore these advances are not a form of credit enhancement.

Credit Enhancement:	1) Excess Interest; 2) Overcollateralization (“OC”); and 3) Subordination.

Allocation of Losses:	Any Realized Losses on the Mortgage Loans will be allocated on any Distribution Date, first, to Net Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider, if any, second, to the Class CE Certificates, third, to the Class M-9 Certificates, fourth, to the Class M-8 Certificates, fifth, to the Class M-7 Certificates, sixth, to the Class M-6 Certificates, seventh, to the Class M-5 Certificates, eighth, to the Class M-4 Certificates, ninth, to the Class M-3 Certificates, tenth, to the Class M-2 Certificates and eleventh, to the Class M-1 Certificates. There will be no allocation of Realized Losses to the Class A Certificates. Investors in the Class A Certificates should note, however, that although Realized Losses cannot be allocated to such Certificates, under certain loss scenarios there may not be enough principal and interest on the Mortgage Loans to distribute to the holders of the Class A Certificates all principal and interest amounts to which they are then entitled.

	Once Realized Losses have been allocated to the Mezzanine Certificates, such amounts with respect to such Certificates will no longer accrue interest and such amounts will not be reinstated thereafter. However, the amount of any Realized Losses allocated to the Mezzanine Certificates may be distributed to such certificates on a subordinated basis on any Distribution Date from Net Monthly Excess Cashflow, to the extent available on such Distribution Date and any Net Swap Payments paid by the Swap Provider and available for this purpose.


ACE Securities Corp. Home Equity Loan Trust, Series 2007-HE2

Transaction Overview (Cont.)

Required Overcollateralization Amount:	Overcollateralization refers to the amount by which the aggregate principal balance of the Mortgage Loans exceeds the aggregate certificate principal balance of the Certificates. This excess (the “Overcollateralization Amount”) is intended to protect the certificateholders 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 approximately 5.00% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. On or after the Stepdown Date and provided that a trigger event is not in effect, the Required Overcollateralization Amount may be permitted to decrease to approximately 10.00% of the aggregate principal balance of the Mortgage Loans as of the last day of the related Due Period, subject to a floor amount of approximately 0.50% of the aggregate outstanding principal balance as of the Cut-off Date. If, due to losses, the Overcollateralization Amount is reduced below the Required Overcollateralization Amount, excess spread, if any is available, will be paid to the certificates then entitled to receive distributions in respect of principal in order to reduce the certificate principal balance of such certificates to the extent necessary to reach the Required Overcollateralization Amount. In addition, Net Swap Payments paid by the Swap Provider may be used to restore or maintain the Required Overcollateralization Amount.

Overcollateralization Interest Amount:	An Overcollateralization Increase Amount for any Distribution Date is the lesser of (i) the Net Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider, if any, for that Distribution Date and (ii) the excess of the Required Overcollateralization Amount over the current Overcollateralization Amount.

Overcollateralization Reduction Amount:	An Overcollateralization Reduction Amount for any Distribution Date is the amount by which the current Overcollateralization Amount exceeds the Required Overcollateralization Amount after taking into account all other distributions to be made on the Distribution Date limited to the distribution of principal on the Mortgage Loans.

Stepdown Date:	Is the earlier of (i) the first Distribution Date after which the aggregate certificate principal balance of the Class A Certificates has been reduced to zero and (ii) the later to occur of (x) the Distribution Date occurring in March 2010 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 principal to the holders of the certificates) is equal to or greater than approximately 51.00%.

Credit Enhancement Percentage:	The Credit Enhancement Percentage for any class of certificates and any Distribution Date is the percentage obtained by dividing (x) the aggregate certificate principal balance of the class or classes subordinate thereto (which includes the Overcollateralization Amount) by (y) the aggregate principal balance of the Mortgage Loans, calculated after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period.

Transaction Overview (Cont.)

Net Monthly Excess Cashflow:		For any Distribution Date is equal to the sum of (i) any Overcollateralization Reduction Amount and (ii) the excess of the Available Distribution Amount, net of any Net Swap Payment and the Swap Termination Payment, if any, required to be made by the Securities Administrator, on behalf of the supplemental interest trust (described below), to the Swap Provider under the Swap Agreement, over the sum of (w) with respect to the Class A Certificates, the Senior Interest Distribution Amount for such Distribution Date, (x) with respect to the Mezzanine Certificates, the Interest Distribution Amount for such Distribution Date and (y) the amount of principal remittance required to be distributed to the holders of the Certificates on such Distribution Date.

Net WAC Pass- Through Rate:		Class A-1 and Class A-2 Certificates: The per annum rate (subject to adjustment based on the actual number of days elapsed in the related Interest Accrual Period) equal to the product of (i) 12 and (ii) a fraction, expressed as a percentage, the numerator of which is the difference of (a) the amount of interest which accrued on the Mortgage Loans in the related loan group in the prior calendar month minus the fees payable to the Servicers, Master Servicer and the Credit Risk Manager with respect to the related Mortgage Loans for such Distribution Date, over (b) the Group I Allocation Percentage or Group II Allocation Percentage, as applicable, of any Net Swap Payment or Swap Termination Payment made to the Swap Provider for such Distribution Date (which was not caused by a Swap Provider Trigger Event, as defined in the Swap Agreement), and the denominator of which is the aggregate principal balance of the Mortgage Loans in the related loan group as of the last day of the immediately preceding Due Period (or as of the Cut-off Date with respect to the first Distribution Date), after giving effect to principal prepayments received during the related Prepayment Period. Mezzanine Certificates: The per annum rate equal to the weighted average (weighted in proportion to the results of subtracting from the aggregate principal balance of each loan group, the certificate principal balance of the related Class A Certificates), of (i) the Net WAC Pass-Through Rate for the Class A-1 Certificates and (ii) the Net WAC Pass-Through Rate for the Class A-2 Certificates. Group I Allocation Percentage: The aggregate principal balance of the Group I Mortgage Loans divided by the sum of the aggregate principal balance of the Group I Mortgage Loans and the Group II Mortgage Loans. Group II Allocation Percentage: The aggregate principal balance of the Group II Mortgage Loans divided by the sum of the aggregate principal balance of the Group I Mortgage Loans and the Group II Mortgage Loans.

Net WAC Rate Carryover Amount:		If on any Distribution Date the Pass-Through Rate for any class of certificates is limited by the related Net WAC Pass-Through Rate, such class will be entitled to the “Net WAC Rate Carryover Amount” which will be equal to the sum of (i) the excess of, if any, (a) the amount of interest that would have accrued on such class based on one-month LIBOR plus the related margin over (b) the amount of interest accrued on such class based on the related Net WAC Pass-Through Rate and (ii) the unpaid portion of any related Net WAC Rate Carryover Amount from the prior Distribution Date together with accrued interest on such unpaid portion at a rate equal to one-month LIBOR plus the related margin for the most recently ended Interest Accrual Period. Any Net WAC Rate Carryover Amount will be paid on such Distribution Date or future Distribution Dates to the extent of funds available. The Net WAC Rate Carryover Amount will be distributed from certain amounts received by the Securities Administrator, on behalf of the Supplemental Interest Trust (described below), under the Swap Agreement, if any, and from the Net Monthly Excess Cashflow on a subordinated basis on the same Distribution Date or on any subsequent Distribution Date to the extent of available funds. The ratings on each class of certificates do not address the likelihood of the payment of any Net WAC Rate Carryover Amount from Net Monthly Excess Cashflow.


ACE Securities Corp. Home Equity Loan Trust, Series 2007-HE2

Transaction Overview (Cont.)

Group I Cap Agreement:	On the Closing Date, the Trustee will enter into a “Group I Cap Agreement”, which will be effective for the period commencing on the Distribution Date occurring in March 2007 and ending immediately following the Distribution Date occurring in August 2007, to make payments in respect of any Net WAC Rate Carryover Amounts in respect of the Class A-1 Certificates and the Mezzanine Certificates as described herein. The Group I Cap Agreement requires a cap payment in an amount equal to the product of: (1) the excess, if any, of one-month LIBOR over a specified strike rate for the related Distribution Date; (2) the related scheduled notional amount, which is based on the lesser of (i) the expected amortization of the Group I Mortgage Loans and (ii) Group I Cap Schedule and (3) a fraction, the numerator of which is the actual number of days elapsed from the previous Distribution Date to but excluding the current Distribution Date (or, for the first Distribution Date, the actual number of days elapsed from the Closing Date to but excluding the first Distribution Date), and the denominator of which is 360.

Group II Cap Agreement:	On the Closing Date, the Trustee will enter into a “Group II Cap Agreement”, which will be effective for the period commencing on the Distribution Date occurring in March 2007 and ending immediately following the Distribution Date occurring in August 2007, to make payments in respect of any Net WAC Rate Carryover Amounts in respect of the Class A-2A, Class A-2B, Class A-2C, Class A-2D Certificates and the Mezzanine Certificates as described herein. The Group II Cap Agreement requires a cap payment in an amount equal to the product of: (1) the excess, if any, of one-month LIBOR over a specified strike rate for the related Distribution Date; (2) the related scheduled notional amount, which is based on the lesser of (i) the expected amortization of the Group II Mortgage Loans and (ii) Group II Cap Schedule and (3) a fraction, the numerator of which is the actual number of days elapsed from the previous Distribution Date to but excluding the current Distribution Date (or, for the first Distribution Date, the actual number of days elapsed from the Closing Date to but excluding the first Distribution Date), and the denominator of which is 360.

Transaction Overview (Cont.)

Swap Agreement:		On the Closing Date, the Trustee will enter into a Swap Agreement with the Swap Provider as described in the final prospectus supplement. The Swap Agreement will have an initial notional amount of $633,135,825. Under the Swap Agreement, commencing on the Distribution Date occurring in September 2007, the trust (through a supplemental interest trust) will be obligated to pay an amount equal to the product of (i) [5.10]% per annum, (ii) the Swap Notional Amount (as defined below) and (iii) a fraction, the numerator of which is 30 and the denominator of which is 360, and the Swap Provider will be obligated to pay to the supplemental interest trust, for the benefit of the holders of the Offered Certificates, an amount equal to the product of (i) one-month LIBOR, (ii) the Swap Notional Amount and (iii) a fraction, the numerator of which is the actual number of days elapsed during the related Interest Accrual Period and the denominator of which is 360, until the Swap Agreement is terminated. The “Swap Notional Amount” for each Distribution Date will be equal to the lesser of (a) the aggregate certificate principal balance of the Offered Certificates on the day immediately preceding such Distribution Date, and (b) the scheduled swap notional amount set forth in the Swap Agreement for such Distribution Date. Only the net amount of the two obligations will be paid by the appropriate party (the “Net Swap Payment”). See the attached schedule. A separate trust created under the pooling and servicing agreement (the “Supplemental Interest Trust”) will hold the Swap Agreement. The Swap Agreement and any payments made by the Swap Provider thereunder will be assets of the Supplemental Interest Trust but will not be assets of any REMIC. Upon early termination of the Swap Agreement, the Supplemental Interest Trust or the Swap Provider may be liable to make a termination payment (the ‘‘Swap Termination Payment’’) to the other party (regardless of which party caused the termination). The Swap Termination Payment will be computed in accordance with the procedures set forth in the Swap Agreement. In the event that the Securities Administrator, on behalf of the Supplemental Interest Trust, is required to make a Swap Termination Payment, that payment will be paid on the related Distribution Date, and on any subsequent Distribution Dates until paid in full, and, if such Swap Termination Payment is not due as a result of the occurrence of a Swap Provider Trigger Event (as defined in the Swap Agreement), such payment will be prior to distributions to Certificateholders.

Available Distribution Amount:		For any Distribution Date, net of the administrative fees, an amount equal to (i) the aggregate amount of scheduled monthly payments on the Mortgage Loans due on the related Due Date and received on or prior to the related Determination Date; (ii) unscheduled payments in respect of the Mortgage Loans (including prepayments, insurance proceeds, liquidation proceeds, subsequent recoveries and proceeds from repurchases of and substitutions for the Mortgage Loans occurring during the Prepayment Period or proceeds from the repurchase of the Mortgage Loans due to the Optional Termination of the Trust); (iii) all P&I Advances with respect to the Mortgage Loans received for the Distribution Date; and (iv) all Compensating Interest paid by the Servicers or the Master Servicer in respect of Prepayment Interest Shortfalls for the related Prepayment Period.

Transaction Overview (Cont.)

Class A Principal Distribution Amount:		Until the Stepdown Date, or if a Trigger Event occurs, the Class A Principal Distribution Amount will be distributed to the holders of the Class A-1 Certificates and the Class A-2 Certificates concurrently, on a pro rata basis based on the related Class A principal allocation percentage (for any Distribution Date, the percentage equivalent of a fraction, the numerator of which is the principal remittance amount for the Group I Mortgage Loans (in the case of the Class A-1 Certificates) or the principal remittance amount for the Group II Mortgage Loans (in the case of the Class A-2 Certificates) and the denominator of which is equal to the principal remittance amount for all of the Mortgage Loans).

		Until the Stepdown Date, or if a Trigger Event occurs, the Class A Certificates will receive the principal collected on the Mortgage Loans plus any excess interest and any Net Swap Payment received by the Securities Administrator from the Swap Provider required to restore or maintain the Required Overcollateralization Amount until the aggregate certificate principal balance of the Class A Certificates has been reduced to zero. On or after the Stepdown Date, if no Trigger Event occurs, principal paid on the Class A Certificates will be an amount such that the Class A Certificates will maintain approximately a 51.00% Credit Enhancement Percentage (2x the Class A Initial Credit Enhancement Percentage). The Class A Principal Distribution Amount will be distributed to the holders of the Class A-1 Certificates and the Class A-2 Certificates to the extent of their respective group-based principal distribution amount.

		Principal distributions to the Class A-2 Certificates will be allocated sequentially to the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, in that order, until the certificate principal balance of each such class has been reduced to zero; provided, however, on any Distribution Date on which the aggregate certificate principal balance of the Mezzanine Certificates has been reduced to zero and the Overcollateralization Amount is zero, all principal distributions will be distributed to the Class A-2 Certificates concurrently, on a pro rata basis, based on the certificate principal balance of each such class, until the certificate principal balance of each such class has been reduced to zero.

Class M Principal Distribution Amount:		Until the Stepdown Date, unless the aggregate certificate principal balance of the Class A Certificates is reduced to zero, the Mezzanine Certificates will not receive any principal payments. On or after the Stepdown Date (if no Trigger Event occurs), principal will be paid to the Mezzanine Certificates, first to the Class M-1 Certificates until it reaches approximately a 42.80% Credit Enhancement Percentage (2x the Class M-1 Initial Credit Enhancement Percentage), second to the Class M-2 Certificates until it reaches approximately a 35.10% Credit Enhancement Percentage (2x the Class M-2 Initial Credit Enhancement Percentage), third to the Class M-3 Certificates until it reaches approximately a 30.30% Credit Enhancement Percentage (2x the Class M-3 Initial Credit Enhancement Percentage), fourth to the Class M-4 Certificates until it reaches approximately a 26.20% Credit Enhancement Percentage (2x the Class M-4 Initial Credit Enhancement Percentage), fifth to the Class M-5 Certificates until it reaches approximately a 22.50% Credit Enhancement Percentage (2x the Class M-5 Initial Credit Enhancement Percentage), sixth to the Class M-6 Certificates until it reaches approximately a 19.00% Credit Enhancement Percentage (2x the Class M-6 Initial Credit Enhancement Percentage), seventh to the Class M-7 Certificates until it reaches approximately a 15.80% Credit Enhancement Percentage (2x the Class M-7 Initial Credit Enhancement Percentage), eighth to the Class M-8 Certificates until it reaches approximately a 12.90% Credit Enhancement Percentage (2x the Class M-8 Initial Credit Enhancement Percentage), ninth to the Class M-9 Certificates until it reaches approximately a 10.00% Credit Enhancement Percentage (2x the Class M-9 Initial Credit Enhancement Percentage
