SECURITIES, PRICING ESTIMATES AND OTHER INFORMATION
The information contained in the attached materials (the “Information”) may include various forms of performance analysis, security characteristics and securities pricing estimates for the securities described therein. Should you receive Information that refers to the “Statement Regarding Assumptions and Other Information”, please refer to this statement instead. The Information is illustrative and is not intended to predict actual results which may differ substantially from those reflected in the Information. Performance analysis is based on certain assumptions with respect to significant factors that may prove not to be as assumed. Performance results are based on mathematical models that use inputs to calculate results. As with all models, results may vary significantly depending upon the value given to the inputs. Inputs to these models include but are not limited to: prepayment expectations (econometric prepayment models, single expected lifetime prepayments or a vector of periodic prepayments), interest rate assumptions (parallel and nonparallel changes for different maturity instruments), collateral assumptions (actual pool level data, aggregated pool level data, reported factors or imputed factors), volatility assumptions (historically observed or implied current) and reported information (paydown factors, rate resets, remittance reports and trustee statements). Models used in any analysis may be proprietary, the results therefore, may be difficult for any third party to reproduce. Contact your registered representative for detailed explanations of any modeling techniques employed in the Information.
The Information may not reflect the impact of all structural characteristics of the security, including call events and cash flow priorities at all prepayment speeds and/or interest rates. You should consider whether the behavior of these securities should be tested using assumptions different from those included in the Information. The assumptions underlying the Information, including structure and collateral, may be modified from time to time to reflect changed facts and circumstances. Offering Documents contain data that is current as of their publication dates and after publication may no longer be accurate, complete or current. Contact your registered representative for Offering Documents, current Information or additional materials, including other models for performance analysis, which are likely to produce different results, and any further explanation regarding the Information.
Any pricing estimates Bear Stearns has supplied at your request (a) represent our view, at the time determined, of the investment value of the securities between the estimated bid and offer levels, the spread between which may be significant due to market volatility or illiquidity, (b) do not constitute a bid by Bear Stearns or any other person for any security, (c) may not constitute prices at which the securities could have been purchased or sold in any market at any time, (d) have not been confirmed by actual trades, may vary from the value Bear Stearns assigns or may be assigned to any such security while in its inventory, and may not take into account the size of a position you have in the security, and (e) may have been derived from matrix pricing that uses data relating to other securities whose prices are more readily ascertainable to produce a hypothetical price based on the estimated yield spread relationship between the securities.
General Information: Bear Stearns and/or individuals associated therewith may have positions in these securities while the Information is circulating or during such period may engage in transactions with the issuer or its affiliates. We act as principal in transactions with you, and accordingly, you must determine the appropriateness for you of such transactions and address any legal, tax or accounting considerations applicable to you. Bear Stearns shall not be a fiduciary or advisor unless we have agreed in writing to receive compensation specifically to act in such capacities. If you are subject to ERISA, the Information is being furnished on the condition that it will not form a primary basis for any investment decision.

Optional Call: | The terms of the transaction allow for a clean-up call (the “Clean-up Call”), which may be exercised on the distribution date the aggregate stated principal balance of the Mortgage Loans has been reduced to less than or equal to 10% of the sum of the Original Pre-Funded Amount and the aggregate stated principal balance of the Mortgage Loans as of the Cut-off Date. |

Mortgage Loans: | The Trust will consist of fixed-rate and adjustable-rate mortgage loans secured by first and second liens on the mortgaged properties with an aggregate principal balance as of the sample pool calculation date (the “Sample Pool Calculation Date Balance”) of approximately $[795,601,639] (the “Mortgage Loans”) The Mortgage Loans have the characteristics as of the Sample Pool Calculation Date described in the collateral tables included in this free writing prospectus. |
The collateral tables included in this free writing prospectus as Appendix A represent a sample pool of Mortgage Loans (the “Sample Pool”) having the characteristics described therein as of the Sample Pool Calculation Date, and do not include additional Mortgage Loans expected to be included in the Trust on the Closing Date. The final pool of Mortgage Loans to be included in the Trust will be different from the Sample Pool, although the characteristics of such final pool will not materially differ from the characteristics of the Sample Pool as indicated herein. |
Original Pre-Funded Amount: | A deposit of not more than $[199,700,000] (the “Pre-Funded Amount”) will be made to a pre-funding account (the “Pre-Funding Account”) on the Expected Closing Date for the benefit of the Class A, Class M and Class B Certificates. From the Expected Closing Date to no later than June 29, 2007 (the “Funding Period”), the Original Pre-Funded Amount on deposit in the Pre-Funding Account will be used to purchase subsequent Mortgage Loans (the “Subsequent Mortgage Loans”). Any portion of the Original Pre-Funded Amount remaining on the last day of the Funding Period will be distributed, as described under “Certificates Priority” on the immediately following Distribution Date. |
Pre-Funded Amount: | The amount on deposit in the Pre-Funding Account on any date of determination. |
Pass-Through Rate: | The Pass-Through Rate for each class of Certificates will be equal to the least of (a) one-month LIBOR plus the margin for such class, (b) 11.50% per annum and (c) the applicable Net WAC Rate. |
LPMI Rate: | Approximately [9.53]% of the Mortgage Loans, by Sample Pool Calculation Date Balance of the Mortgage Loans, are covered by lender-paid mortgage insurance policies. The “LPMI Rate” for any period will equal the per annum premium rate of each such insured Mortgage Loan for that period expressed as a weighted average rate for the applicable Mortgage Loans. As of the Sample Pool Calculation Date, the weighted average LPMI Rate is approximately [0.092]% per annum of the Mortgage Loans. |
Net Mortgage Rate: | The “Net Mortgage Rate” will be a per annum rate equal to the excess of the weighted average of the mortgage rates on the Mortgage Loans minus the sum of (a) a weighted average sub-servicing fee rate (which is expected to be approximately [0.354]% per annum as of the Closing Date), (b) a master servicing fee rate of [0.030]% per annum, (c) a trustee fee rate of [0.0025]% and (d) the LPMI Rate. |

The Net WAC Rate will be adjusted to an effective rate reflecting the accrual of interest on an actual/360 basis. |
Net WAC Rate
Shortfall: | Any shortfalls in interest payments on any Class A, Class M or Class B Certificates resulting from the excess, if any, of (a) interest accrued on the Certificates at one-month LIBOR plus the related margin (up to the maximum rate of 11.50% per annum) over (b) interest accrued on the Certificates at the applicable Net WAC Rate (any such shortfalls, “Net WAC Rate Shortfalls”), on each Distribution Date, plus unpaid Net WAC Rate Shortfalls from prior Distribution Dates to be paid in the current month or carried forward for payment on subsequent Distribution Dates, together with interest thereon at the applicable Pass-Through Rate for the current Distribution Date, as described under “Certificates Priority of Distribution” below. |

Overcollateralization: | With respect to any Distribution Date, the outstanding principal balance of the Mortgage Loans as of the last day of the related Due Period plus the Pre-Funded Amount less the aggregate Certificate Principal Balance of the Class A, Class M, Class B and Class P Certificates (after taking into account all distributions of principal on such Distribution Date). |
Any Realized Losses on the Mortgage Loans will be covered first by the Excess Cashflow and then by the Overcollateralization, if any. If the Overcollateralization is thereafter reduced, the Excess Cashflow will be directed to pay principal on the Certificates, resulting in the limited acceleration of the Certificates relative to the amortization of the Mortgage Loans, until the Overcollateralization reaches the Overcollateralization Target. Upon this event, the acceleration feature will cease, unless the amount of Overcollateralization is reduced below the Overcollateralization Target by Realized Losses on the Mortgage Loans. |
Overcollateralization
Target: | For each Distribution Date prior to the Stepdown Date, [0.95]% of the sum of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date and the Original Pre-Funded Amount (the “Overcollateralization Target”). The initial amount of Overcollateralization will be approximately [0.95]% as of the Cut-off Date. |
On or after the Stepdown Date, the Overcollateralization Target will be equal to 1.90% of the aggregate principal balance of the Mortgage Loans for the related Distribution Date, subject to a floor of 0.50% of the sum of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date and the Original Pre-Funded Amount; provided, however, that if a Trigger Event (as described herein) is in effect on the related Distribution Date, the Overcollateralization Target will be equal to the Overcollateralization Target on the prior Distribution Date. |
Excess
Cashflow: | “Excess Cashflow” for any Distribution Date will be equal to the available funds for the Mortgage Loans remaining after interest and principal distributions on the Certificates (not including the Class C, Class P and Class R Certificates) as described pursuant to clauses (1) to (5) under “Certificates Priority of Distributions - Mortgage Loans.” |

Insurance Policy: | Ambac Assurance Corporation will guarantee the ultimate payment of principal and current interest shortfalls on the Class AM Certificates only, except shortfalls and losses resulting from prepayment interest shortfalls, Relief Act shortfalls and Net WAC Rate Shortfalls. Ambac’s claims paying ability is rated “AAA” and “Aaa” by S&P and Moody’s, respectively. |
Trigger Event: | “Trigger Event” will be in effect on any Distribution Date on or after the Stepdown Date if either (or both) a Delinquency Trigger or a Cumulative Loss Trigger is in effect on such Distribution Date. |
Delinquency Trigger: | With respect to the Certificates, a “Delinquency Trigger” will occur if the three month rolling average 60+ day delinquency percentage (including bankruptcy, foreclosures, and REO) for the outstanding Mortgage Loans equals or exceeds [42.00]% times the Senior Enhancement Percentage. As used above, the “Senior Enhancement Percentage” with respect to any Distribution Date is the percentage equivalent of a fraction, (a) the numerator of which is equal to: the excess of (i) the aggregate principal balance of the Mortgage Loans for such distribution date (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) over (ii) (1) before the Certificate Principal Balances of the Class A Certificates have been reduced to zero, the sum of the Certificate Principal Balances of the Class A Certificates (after taking into account distribution of the Principal Distribution Amount for such distribution date), or (2) after such time, the Certificate Principal Balance of the most senior class of Subordinate Certificates outstanding (after taking into account distribution of the Principal Distribution Amount for such distribution date) and (b) the denominator of which is equal to the aggregate principal balance of the Mortgage Loans for such distribution date (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). |

Cumulative Loss
Trigger: | With respect to the Certificates, a “Cumulative Loss Trigger” will occur if the aggregate amount of Realized Losses on the Mortgage Loans exceeds the applicable percentage of the sum of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date and the Original Pre-Funded Amount, as set forth below: |
Period (month) | Percentage |
25 - 36 | [0.25]% with respect to May 2009, plus an additional 1/12th of [0.45]% for each month thereafter |

61 - 72 | [1.75]% with respect to May 2012, plus an additional 1/12th of [0.30]% for each month thereafter |
73+ | [2.05]% |
Allocated Realized
Loss Amounts: | With respect to any class of Certificates and any Distribution Date, an amount equal to the sum of any Realized Loss allocated to that class of Certificates on that Distribution Date and any Allocated Realized Loss Amount for that class remaining unpaid from any previous Distribution Date. Allocated Realized Loss Amounts allocated to the Class AM Certificates will be covered by the Certificate Insurance Policy. |
Stepdown Date: | The earlier to occur of (x) the Distribution Date following the Distribution Date on which the aggregate Certificate Principal Balance of the Class A Certificates is reduced to zero and (y) the later to occur of: (i) the Distribution Date in May 2010 or (ii) the first Distribution Date on which the aggregate Certificate Principal Balance of the Class A Certificates is less than or equal to 86.50% of the aggregate principal balance of the Mortgage Loans and the Pre-Funded Amount for such Distribution Date. |
Certificate Principal Balance: | With respect to any Certificate as of any date of determination, the initial Certificate Principal Balance thereof, increased by any subsequent recoveries allocated thereto, and reduced by the aggregate of (a) all amounts allocable to principal previously distributed with respect to such Certificate and (b) any reductions in the Certificate Principal Balance thereof in connection with allocations of Realized Losses. |
