Filed Pursuant to Rule 433 Registration No. 333-118843 [Banc of America Securities Logo] - -------------------------------------------------------------------------------- Because the asset-backed securities are being offered on a "when, as and if issued" basis, any contract of sale will terminate, by its terms, without any further obligation or liability between us, if the securities themselves, or the particular class to which the contract relates, are not issued. Because the asset-backed securities are subject to modification or revision, any such contract also is conditioned upon the understanding that no material change will occur with respect to the relevant class of securities prior to the closing date. If a material change does occur with respect to such class, our contract will terminate, by its terms, without any further obligation or liability between us (the "Automatic Termination"). If an Automatic Termination occurs, we will provide you with revised offering materials reflecting the material change and give you an opportunity to purchase such class. To indicate your interest in purchasing the class, you must communicate to us your desire to do so within such timeframe as may be designated in connection with your receipt of the revised offering materials.

The U.S. Department of Labor has extended to Banc of America Securities LLC an administrative exemption (the "Exemption") from certain of the prohibited transaction rules of ERISA and the related excise tax provisions of Section 4975 of the Code with respect to the initial purchase, the holding and the subsequent resale by certain Plans of certificates in pass-through trusts that consist of certain receivables, loans and other obligations that meet the conditions and requirements of the Exemption. The Exemption may cover the acquisition and holding of the Offered Certificates by the Plans to which it applies provided that all conditions of the Exemption other than those within the control of the investors are met. In addition, as of the date hereof, there is no single mortgagor that is the obligor on 5% of the initial balance of the Mortgage Pool. If there are Mortgage Loans with loan-to-value ratios in excess of 100% in the Mortgage Pool or in a loan group within the Mortgage Pool, the Exemption will not cover the acquisition and holding of the related offered Super Senior Support or Subordinate Certificates. Prospective Plan investors should consult with their legal advisors concerning the impact of ERISA, the Code and Similar Law, the applicability of PTE 83-1 and the Exemption, and the potential consequences in their specific circumstances, prior to making an investment in the Offered Certificates. Moreover, each Plan fiduciary should determine whether under the governing plan instruments and the applicable fiduciary standards of investment prudence and diversification, an investment in the Offered Certificates is appropriate for the Plan, taking into account the overall investment policy of the Plan and the composition of the Plan's investment portfolio.

You must report income received on your Offered Certificates as it accrues from Distribution Date to Distribution Date, even if it is before such income is distributed in cash to you. Certain classes of Offered Certificates may be issued with "original issue discount." If your class of Offered Certificates is issued with original issue discount, you must report original issue discount income over the life of your Certificate, often well before such income is distributed in cash to you. If you hold an Offered Certificate that has the benefit of a yield maintenance agreement and is entitled to certain payments from a reserve account, you will be treated as owning two assets, a REMIC regular interest and the right to receive payments from the reserve fund and will be required to account separately for each of these assets for federal income tax purposes.

If the Mortgage Loans are divided into multiple loan groups with more than one set of Subordinate Certificates, the Depositor may, at its option, subject to certain conditions, purchase the Mortgage Loans in one or some of the loan groups, which would effect an early retirement of only the related Certificates. The Pooling Agreement: The Certificates will be issued pursuant to a Pooling and Servicing Agreement (the "Pooling Agreement") to be dated the Closing Date, among the Depositor, the Servicer and the Trustee. The Mortgage Pool: The "Mortgage Pool" will consist of fixed rate, conventional, fully-amortizing mortgage loans (the "Mortgage Loans") secured by first liens on one- to four-family properties. All of the Mortgage Loans were originated or acquired by Bank of America, National Association, which is an affiliate of the Depositor and Banc of America Securities LLC. In addition, certain of the Mortgage Loans were originated using underwriting standards that are different from, and in certain respects, less stringent than the general underwriting standards of Bank of America, National Association. See "Underwriting Guidelines of Bank of America" below. The Mortgage Pool may be divided into multiple loan groups. The Mortgage Loans: The Mortgage Loans consist of fixed rate, conventional, fully amortizing mortgage loans secured by first liens on one- to four-family residential properties. Substantially all of the Mortgage Loans will have original terms to stated maturity of approximately 20 to 30 years. Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at any time. If indicated in the Collateral Summary at the end of this Free Writing Prospectus, certain of the Mortgage Loans may be subject to prepayment premiums. Accordingly, the actual date on which any Mortgage Loan is paid in full may be earlier than the stated maturity date due to unscheduled payments of principal. See the Collateral Summary at the end of this Free Writing Prospectus for more information about the Mortgage Loans.

With respect to each Yield Maintenance Agreement for any Distribution Date (other than the initial Distribution Date) if LIBOR, as calculated for the Interest Accrual Period related to such Distribution Date, exceeds a designated strike percentage, the Counterparty will be obligated to pay to the Trustee, for deposit into the related Reserve Fund, an amount equal to the product of (a) the amount by which (i) the lesser of LIBOR and a designated maximum percentage exceeds (ii) the designated strike percentage, (b) the related notional amount as set forth for such Distribution Date in the related Yield Maintenance Agreement and (c) one-twelfth. Pursuant to the Pooling Agreement, the Trustee will establish a separate trust account (the "Reserve Fund") for deposit of any payments that it may receive under a Yield Maintenance Agreement. Each Reserve Fund is part of the trust fund but will not be an asset of any REMIC. Compensating Interest: Amounts on deposit in a Reserve Fund will be used to make certain payments on a specified Class of Certificates that has the benefit of a Yield Maintenance Agreement. Pursuant to the Pooling Agreement, the aggregate Servicing Fee payable to the Servicer for any month will be reduced (but not below zero) by an amount equal to the lesser of (i) the aggregate of the Prepayment Interest Shortfalls for such Distribution Date and (ii) one-twelfth of 0.25% of the aggregate Stated Principal Balance of the Mortgage Loans as of the due date in the month preceding the month of such Distribution Date (such amount, the "Compensating Interest"). If a group of Subordinate Certificates supports multiple groups of Senior Certificates, Compensating Interest will be determined on an aggregate basis with respect to all related loan groups. If a group of Subordinate Certificates supports one group of Senior Certificates, Compensating Interest will be determined for the related loan group. Advances: Subject to the certain limitations, the Servicer will be required pursuant to the Pooling Agreement to advance (any such advance, an "Advance") prior to each Distribution Date an amount equal to the aggregate of payments of principal and interest (net of the Servicing Fee) which were due on the related due date on the Mortgage Loans and which were delinquent on the related Determination Date. Advances made by the Servicer will be made from its own funds or funds available for future distribution. The obligation to make an Advance with respect to any Mortgage Loan will continue until the ultimate disposition of the REO Property or Mortgaged Property relating to such Mortgage Loan.

The initial Regular Interest Accrual Period will be deemed to have commenced on February 1, 2006 and any initial LIBOR Based Interest Accrual Period or No Delay Interest Accrual Period will be deemed to have commenced on February 25, 2006. On each Distribution Date, to the extent of the applicable Pool Distribution Amount or Amounts, each class of interest-bearing Certificates will be entitled to receive interest (as to each such class, the "Interest Distribution Amount") with respect to the related Interest Accrual Period. The Interest Distribution Amount for any interest-bearing class of Certificates will be equal to the sum of (i) interest accrued during the related Interest Accrual Period at the applicable pass-through rate on the related Class Balance or notional amount and (ii) the sum of the amounts, if any, by which the amount described in clause (i) above on each prior Distribution Date exceeded the amount actually distributed in respect of interest on such prior Distribution Dates and not subsequently distributed. The interest entitlement described in clause (i) of the Interest Distribution Amount for each class of interest-bearing Senior Certificates and each class of Subordinate Certificates will be reduced by the amount of Net Interest Shortfalls for the related Mortgage Loans for such Distribution Date. Allocations of the interest portion of Realized Losses on the Mortgage Loans in a loan group first to the related Subordinate Certificates in reverse numerical order will result from the priority of distributions first to the related Senior Certificates and then to the classes of related Subordinate Certificates in numerical order of the applicable Pool Distribution Amount as described below under "Priority of Distributions." After the date on which the aggregate Class Balance of the related Subordinate Certificates has been reduced to zero, the interest-bearing related Senior Certificates will bear the interest portion of any Realized Losses on such Mortgage Loans pro rata based on the interest entitlement described in clause (i) of the applicable Interest Distribution Amount.

With respect to each class of Subordinate Certificates, if on any Distribution Date the Fractional Interest is less than the Fractional Interest for that class on the Closing Date, no classes of Subordinate Certificates in the same group, if there is more than one group of Subordinate Certificates, junior to such class will be entitled to receive a principal distribution. Distributions of principal on the Subordinate Certificates that are entitled to receive a principal distribution on a Distribution Date will be made sequentially to each class of Subordinate Certificates in the order of their numerical class designations until each such class has received its respective pro rata share for the Distribution Date. However, the Class PO Deferred Amounts will be paid to the ratio strip components or certificates from amounts otherwise payable as principal to the related Subordinate Certificates, beginning with the amounts otherwise distributable as principal to the class of related Subordinate Certificates with the highest numerical designation. Shifting Interest Structure: Additional credit enhancement is provided by the allocation of the applicable Non-PO Percentages of principal prepayments on the Mortgage Loans in the Mortgage Pool or a loan group in the Mortgage Pool to the related Senior Certificates for the first five years and the disproportionately greater allocation of prepayments to such Senior Certificates over the following four years. The disproportionate allocation of the applicable Non-PO Percentages of prepayments on the Mortgage Loans in the Mortgage Pool or a loan group in the Mortgage Pool will accelerate the amortization of those Senior Certificates relative to the amortization of the Subordinate Certificates. As a result, the credit support percentage for the Senior Certificates should be maintained and may be increased during the first nine years.

Such allocation will be effected on each Distribution Date by reducing the Class Balance of the ratio strip certificate or principal balance of the ratio strip component of the related group if and to the extent that such balance (after taking into account the amount of all distributions to be made on such Distribution Date) exceeds the Adjusted Pool Amount (PO Portion) for such Distribution Date. The amount of any such Realized Loss allocated to a ratio strip certificate or ratio strip component of the related group will be treated as a "Class PO Deferred Amount." To the extent funds are available on such Distribution Date or on any future Distribution Date from amounts that would otherwise be allocable to the related Subordinate Principal Distribution Amount or Amounts, the Class PO Deferred Amounts for the ratio strip certificate or ratio strip component of the related group will be paid on such ratio strip certificate or ratio strip component of the related group prior to distributions of principal on the related Subordinate Certificates.

The Class Balance of the class of related Subordinate Certificates then outstanding with the highest numerical class designation will be reduced by the amount of any payments in respect of Class PO Deferred Amounts for the ratio strip certificate or ratio strip component of the related group. Any excess of these Class PO Deferred Amounts over the Class Balance of that class will be allocated to the next most subordinate class of related Subordinate Certificates to reduce its Class Balance and so on, as necessary. On each Distribution Date, the applicable Non-PO Percentage of any Realized Loss will be allocated first to the related Subordinate Certificates in the reverse order of their numerical class designations (beginning with the class of related Subordinate Certificates then outstanding with the highest numerical class designation), in each case until the Class Balance of such class of Certificates has been reduced to zero, and then to the Senior Certificates or to the Senior Certificates of the related group, if there are multiple groups of Senior Certificates pro rata based on their respective Class Balances.

If the Senior Certificates are divided into multiple groups, the Subordinate Certificates may or may not consist of multiple groups. If there are multiple groups of Subordinate Certificates, each group will support one or more groups of Senior Certificates. Additional credit enhancement is provided by the allocation of the applicable Non-PO Percentages of all principal prepayments on the applicable Mortgage Loans to the related Senior Certificates, subject to certain exceptions, for the first five years and the disproportionately greater allocation of prepayments to such Senior Certificates over the following four years. The disproportionate allocation of the applicable Non-PO Percentages of prepayments on the Mortgage Loans will accelerate the amortization of those Senior Certificates relative to the amortization of the related Subordinate Certificates. As a result, the credit support percentage for the Senior Certificates should be maintained and may be increased during the first nine years. The initial credit support percentage for the Senior Certificates (calculated by dividing the initial Class Balance of the related Subordinate Certificates by the related Pool Principal Balance) is expected to be 4.25% (+/- 50 basis points). Priority of Distributions ------------------------- Distributions will be made on each Distribution Date from the Pool Distribution Amount (if the Mortgage Pool is not divided into loan groups) or Amounts (if there are multiple loan groups, in which case the Senior Certificates and any components of a group will be paid from the related Pool Distribution Amount) in the following order of priority: ------------------------------------------------------------ First, to the classes of Senior Certificates and component (if any) entitled to payments of interest, to pay interest; ------------------------------------------------------------ | | | V ------------------------------------------------------------ Second, pro rata, to the Senior Certificates (other than any ratio strip certificates) and any ratio strip component or ratio strip certificates entitled to payments of principal, to pay principal; ------------------------------------------------------------ | | | V ------------------------------------------------------------ Third, to any ratio strip component or ratio strip certificates, to pay any Class PO Deferred Amounts, from amounts otherwise payable as principal to the related Subordinate Certificates; ------------------------------------------------------------ | | | V ------------------------------------------------------------ Fourth, subject to any cross-collateralization payments, sequentially, to each class of Subordinate Certificates from the related Pool Distribution Amount or Amounts to pay interest and principal in the order of numerical class designations, until each Class Balance is zero; and ------------------------------------------------------------ | | | V ------------------------------------------------------------ Fifth, to the residual certificate, any remaining amounts. ------------------------------------------------------------ Banc of America Securities LLC 23 - -------------------------------------------------------------------------------- The depositor has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates.

During the application process, the applicant is required to authorize Bank of America to obtain a credit report that summarizes the applicant's credit history with merchants and lenders and any record of bankruptcy or prior foreclosure. This credit information may be obtained from either a single credit repository or from up to three credit repositories. The credit bureau inquiry also includes a request for the applicant's Credit Score. "Credit Scores" are statistical credit scores obtained by many mortgage lenders in connection with the loan application to help assess a borrower's creditworthiness. Credit Scores are generated by models developed by a third party and are made available to lenders through three national credit bureaus, Experian (FICO), Equifax (Beacon) and TransUnion (Empirica). The models were derived by analyzing data on consumers in order to establish patterns which are believed to be indicative of the borrower's probability of default. A Credit Score is based on a borrower's historical credit data, including, among other things, payment history, delinquencies on accounts, levels of outstanding indebtedness, length of credit history, types of credit, and bankruptcy experience. Credit Scores range from approximately 300 to approximately 850, with higher scores indicating an individual with a more favorable credit history compared to an individual with a lower score. If the credit bureaus cannot generate a Credit Score due to insufficient information about an applicant, Bank of America will consider proof of an applicant's alternative credit history, such as a history of consistent rent and utility payments. In addition to a Credit Score, Bank of America may obtain a Custom Mortgage Score. In order to generate a Custom Mortgage Score, the applicant must have at least one trade line on his or her credit report and also have a Credit Score. The "Custom Mortgage Score" was developed on a population of mortgage loans serviced by Bank of America and is designed to assess the likelihood that a mortgage loan will become 60 days or more delinquent within two years of application. The Custom Mortgage Score used by Bank of America will either have been developed by Bank of America individually or with the assistance of a third party. The Custom Mortgage Score requires a Credit Score and utilizes information obtained from one of the three major credit bureaus. The credit bureau used depends on the geographic location of the applicant's residence at the time of application. Bank of America may evaluate a prospective borrower's creditworthiness with either (i) a Credit Score, (ii) a Custom Mortgage Score or (iii) a combination of a Credit Score and a Custom Mortgage Score.

These underwriting standards applied by Bank of America in originating or acquiring mortgage loans are intended to evaluate the applicants' repayment ability, credit standing, and the adequacy of the mortgage property as collateral for the mortgage loan. The underwriting standards as established in the Product Guides are continuously updated to reflect prevailing conditions in the residential market, new mortgage products, and the investment market for residential mortgage loans. Each mortgage application is evaluated by either an automated underwriting decision engine and/or a human underwriter to determine the appropriate credit decision and documentation requirements for the loan transaction. The automated underwriting decision engine may be an engine developed by an outside company and updated by Bank of America risk management personnel to facilitate automated decisions on Bank of America loan transactions. Alternatively, it may be an external decision engine such as Fannie Mae's Desktop Underwriter(R) or Freddie Mac's Loan Prospector(R) decision engines. If the loan is not automatically approved or declined by the automated underwriting decision engine, it is directed to an underwriter who evaluates the application against a set of specific criteria. The underwriter may be an employee of the lender or may be an individual performing underwriting on a contract basis through a third party firm such as a mortgage insurance company. Desktop Underwriter(R) is an automated underwriting system developed by Fannie Mae for conventional conforming loans. Desktop Underwriter(R) indicates the minimum income and asset verification, credit-related documentation and other requirements necessary to complete processing of the loan file. These requirements are based on the specific risk factors present in each loan file. Bank of America utilizes Fannie Mae's Custom Desktop Underwriter(R) which allows Bank of America's conditions and policies to display on a customized findings report specific to it. Loan Prospector(R) is an automated underwriting system developed by Freddie Mac for conventional conforming loans. Loan Prospector(R) indicates the minimum income and asset verification, credit-related documentation and other requirements necessary to complete processing of the loan file. These requirements are based on the specific risk factors present in each mortgage application.

As part of the underwriting evaluation, the Loan-to-Value Ratio is calculated. The "Loan to Value Ratio" is the percentage equal to (i) the principal balance of the mortgage loan at origination divided by (ii) the lesser of (a) the appraised value of the related mortgaged property determined in an appraisal obtained at origination of the mortgage loan or an automated valuation model or tax assessed value (if permitted by the applicable product type) and (b) except for mortgage loans made for refinancing purposes, the sales price for the mortgaged property. In addition to evaluating the Loan-to-Value Ratio, the automated underwriting decision engine or human underwriter will also evaluate the applicant's credit history and/or Credit Score and/or Custom Mortgage Score, the amount of the applicant's debts (including proposed housing payment and related expenses such as property taxes and hazard insurance) to his or her gross monthly income, the intended occupancy of the subject property, the property type, and the purpose of the loan transaction to determine whether the mortgage loan generally meets the guidelines established for the program under which the applicant is applying. If there are multiple applicants on a loan transaction, Bank of America generally utilizes the Credit Score and/or Custom Mortgage Score associated with the highest wage-earner on the transaction as the representative score(s) for the transaction. The automated underwriting decision engine and/or the underwriter may utilize compensating factors to offset one or more features of the loan transaction that may not specifically comply with the product guidelines. Therefore, the application of the underwriting guidelines for a product type by either an underwriter or an automated decision engine does not imply that each specific standard was satisfied individually. A loan is considered to be underwritten in accordance with a given set of guidelines if, based on an overall qualitative evaluation, the loan is in substantial compliance with such underwriting guidelines.

Bank of America's Debt-to-Income Ratio guidelines are based on the loan instrument, loan term, Credit Score, Loan-to-Value Ratio, property type, and occupancy characteristics of the subject loan transaction. Bank of America permits ratios to exceed guidelines when the applicant has documented compensating factors for exceeding ratio guidelines such as documented excess funds in reserves after closing, a history of making a similar sized monthly debt payment on a timely basis, substantial residual income after monthly obligations are met, evidence that ratios will be reduced shortly after closing when a financed property under contract for sale is sold, or additional income has been verified for one or more applicants that is ineligible for consideration as qualifying income. For certain mortgage loans, underwriting may be based on data obtained by third parties that are involved at various stages in the mortgage origination or acquisition process. This typically occurs under circumstances in which loans are subject to more than one approval process, as when correspondents, certain mortgage brokers or similar entities that have been approved by Bank of America to underwrite loans on its behalf, or independent contractors hired by these parties to perform underwriting services on Bank of America's behalf, make initial determinations as to the consistency of loans with established underwriting guidelines. The underwriting of mortgage loans acquired from another lender generally relies on the representations from the originating lender that the mortgage loans were underwritten in accordance with agreed upon underwriting standards that are materially similar to Bank of America's. In the event these standards differ materially from those set forth in this prospectus, the related prospectus supplement will describe the applicable standards. Generally, Bank of America conducts a post-purchase review of a sampling of all mortgage loans acquired from another lender to determine whether agreed upon requirements were met. In order to be eligible to sell mortgage loans under a delegated underwriting arrangement, the lender must meet certain requirements including, among other things, certain quality, operational and financial guidelines. Certain of the mortgage loans may be purchased by Bank of America in negotiated transactions, and these negotiated transactions may be governed by contractual agreements. The contractual agreements may provide the commitment by Bank of America to accept the delivery of a certain dollar amount of mortgage loans over a specific period of time; this commitment may allow for the delivery of mortgage loans one at a time or in multiples as aggregated by the seller. Many of the contractual agreements allow the delegation of all underwriting functions to the seller, who will represent that the mortgage loans have been originated in accordance with underwriting standards agreed to by Bank of America.

First lien refinance transactions may have existing secondary financing with the applicant that is resubordinated to the new first lien transaction or may have new secondary financing originated simultaneously with the first lien mortgage. The secondary financing may or may not be provided by Bank of America. The Total Loan-to-Value Ratio and Combined Loan-to-Value Ratio are evaluated on each loan with subordinate financing. The "Total Loan-to-Value Ratio" is the principal balance of the first lien mortgage loan at origination plus any secondary financing that was drawn upon at that time divided by the value of the mortgaged property. The "Combined Loan-to-Value Ratio" is the principal balance of the first lien mortgage loan at origination plus the total amount of available secondary financing (including any unused amount on a home equity line of credit) divided by the value of the mortgaged property. A mortgage loan with secondary financing is evaluated to determine if the Total Loan-to-Value Ratio and Combined Loan-to-Value Ratio meet the requirements for the program under which the application is submitted or if the application contains compensating factors to warrant an exception to the applicable guidelines. Some applicants request a first lien mortgage loan with a Loan-to-Value Ratio of 80% with a simultaneously funded second lien transaction in order to avoid the cost of primary mortgage insurance associated with first lien mortgage loans with Loan-to-Value Ratios exceeding 80%. Documentation ------------- In assessing an applicant, Bank of America requires supporting documentation (or other verification) for all material data provided by the applicant, such as income and source of down payment, unless the applicant qualifies for one of the Accelerated Processing Programs discussed below. Under Bank of America's standard documentation process (the "Standard Documentation Process") the following verifications are required: a salaried applicant's income is verified by either having the applicant provide copies of the previous year's federal withholding form (IRS W-2) and a current payroll earnings statement or by sending a verification of employment form to the applicant's employer. A verification of employment form asks the employer to report the applicant's length of employment with the employer, the current salary and an indication as to whether it is expected that the applicant will continue to be employed in the future. A self-employed applicant is required to provide copies of tax returns for the prior two years. Bank of America verifies down payment funds by (i) obtaining bank or other financial statements covering the most recent 60-day period confirming the existence of these funds, (ii) determining electronically that these funds are on deposit with Bank of America, (iii) obtaining documentation that these funds are to be obtained from a gift or sale of assets or (iv) asking the applicant's financial institution to complete a verification of deposit form detailing asset information. Asset verifications are not required on refinance transactions.

In order to qualify for Bank of America's general underwriting standards, applicants must be willing to have the income and assets stated on their application verified. Applicants who have indicated that they do not wish to have their income and/or assets verified are directed to other Bank of America programs outlined in "--Bank of America Alternative Underwriting Standards" below. While the applicants under Bank of America's general underwriting standards are willing to have income and asset information stated in the application verified, the level of verifications required (if any) are based on the applicant's credit profile, requested loan terms, and whether the applicant has an existing loan serviced by Bank of America that is being refinanced with the new loan transaction. Bank of America matches documentation requirements on mortgage loans to the overall risk parameters of the loan file under various "Accelerated Processing Programs" such as: (i) Rapid; (ii) PaperSaver (also known as Threshold); (iii) Stated Income, Stated Asset; (iv) All-Ready Home; (v) Mortgage Rewards programs; (vi) No Ratio or (vii) Stated Income. Under Bank of America's "Rapid" documentation program, only the most recent pay stub (if salaried) or first two pages of the most recent tax return (if self-employed) of an applicant is required for income verification and only the most recent bank statement of an applicant is required for asset verification on purchase transactions if the applicant meets the Total Loan-to-Value Ratio and Credit Score requirements for that program. Under Bank of America's "PaperSaver" documentation program, verification of the applicant's stated income and stated assets is not requested (with the exception of self-employed applicants who are required to sign the IRS form 4506-T (Request for Transcript of Tax Returns)) if the applicant meets the designated Credit Score, Custom Mortgage Score, Loan-to-Value Ratios and other eligibility requirements. An applicant with a designated higher Credit Score and designated higher Custom Mortgage Score which together indicate a favorable credit history is eligible for PaperSaver documentation. The PaperSaver documentation program has certain limitations relating to occupancy, property type, purpose and principal balance. Under Bank of America's "Stated Income, Stated Asset" documentation program, which is only available through the wholesale channel, income or asset verifications are not requested from applicants if they meet the Total Loan-to-Value Ratio, Credit Score and other eligibility requirements for the program. Although the Stated Income, Stated Asset program permits applicants to simply state their income and assets without verification, all applicants are required to sign an IRS form 4506 permitting income verification from tax return data if the file is selected as part of Bank of America's quality assurance audit.

Under each of these programs, Bank of America will pay certain closing costs normally paid by the customer. Under these programs, a borrower whose current mortgage loan is serviced by Bank of America does not need to provide income or asset verification documentation if the current mortgage loan has had no 30 day or more delinquent payments in the previous twelve months (or since origination if less than twelve months). In addition, Bank of America typically requires only a drive-by appraisal rather than a an interior inspection appraisal. Because these programs involve the refinancing of mortgage loans that Bank of America originally underwrote, Bank of America will not apply any significant borrower credit or property underwriting standards (other than a minimum Credit Score). Mortgage Loans initially included in the Trust Estate for a particular series may have been the subject of a refinancing described above. To the extent a borrower becomes eligible for the All-Ready Home or Mortgage Rewards program after his or her Mortgage Loan has been included in a particular Trust Estate, his or her Mortgage Loan could be more easily refinanced, resulting in a prepayment of the Mortgage Loan. For a description of the No Ratio and Stated Income programs, see "--Bank of America Alternative Underwriting Standards" below. Collateral Valuation -------------------- Bank of America conducts a valuation of the mortgaged property as collateral for each mortgage loan. This collateral valuation may be determined by (i) an interior inspection appraisal, (ii) a tax assessed value, (iii) a desktop appraisal, (iv) a drive-by appraisal, (v) an automated valuation model, or (vi) reference to the collateral valuation obtained in connection with the origination of the previous loan if the loan is a refinance of a mortgage loan that was previously serviced by Bank of America. An interior inspection appraisal is an appraisal report based on an interior inspection of the subject property. A tax assessed value is a factor applied to the tax value recorded for the subject property that reflects the general relationship between the assessed value and the market value of the property. These factors are established for each county by a third party vendor. A tax assessed value also does not entail any physical inspection of the subject property. A desktop appraisal is a report completed by a certified/licensed appraiser utilizing a sales comparison analysis from a local multiple listing service without conducting a physical inspection of the property. A drive-by appraisal report is a limited, summary appraisal report based on an exterior inspection of the property and comparable sales by a certified/licensed appraiser. An automated valuation model is an electronically generated valuation that utilizes real estate information such as property characteristics, market demographics, sales price data, and regional trends to calculate a value for a specific property. Bank of America utilizes the automated valuation models of several vendors. An automated valuation model does not entail any physical inspection of the subject property. In addition, no updated appraisal valuation may be performed if the loan is a refinance of a loan that was previously serviced by Bank of America and the valuation from the time of origination of the loan being refinanced reflects adequate value for the mortgaged property.

EPA Lead Paint requirements for notice and an inspection period are standard for properties built before 1978. Properties containing other hazards may be eligible for financing if the appraiser can value the property showing the impact of the hazard, and the borrower executes a "hold harmless" letter to the lender. Environmental hazards are not noted on collateral valuations where no physical inspection of the property takes place, such as on loans where the collateral valuation is conducted by an automated valuation model or tax assessed value. Appraisers only note environmental hazards on a desktop appraisal if they generally are known in the area. Certain states have "anti-deficiency" laws which, in general, require lenders providing credit on one to four family properties to look solely to the property for repayment in the event of foreclosure. The underwriting guidelines in all states (including anti deficiency states) require that the value of the property being financed, as indicated by the collateral valuation, currently supports and is anticipated to support in the future the outstanding loan balance and provides sufficient value to mitigate the effects of adverse shifts in real estate values, although there can be no assurance that the value will support the outstanding loan balance in the future. Flood Determinations and Hazard Insurance ----------------------------------------- Each mortgage loan is evaluated to determine if the subject property is located in a federal flood zone. If the property is located in a flood zone, then flood insurance is required on the loan transaction with an amount of coverage that meets or exceeds federal law requirements. Generally, evidence of acceptable hazard insurance coverage on the subject property is a requirement for loan approval. This documentation, however, is not required if the mortgage loan is a refinance of an existing Bank of America serviced loan transaction and hazard insurance was documented for the previous loan transaction or the mortgage loan is originated under a program that does not require the review of evidence of hazard insurance.

Except as noted below in connection with certain refinance transactions, mortgage loans will generally be covered by an appropriate standard form American Land Title Association ("ALTA") title insurance policy, or a substantially similar policy or form of insurance acceptable to Fannie Mae or Freddie Mac, or if the related mortgaged property is located in a jurisdiction where these policies are generally not available, an opinion of counsel of the type customarily rendered in these jurisdiction in lieu of title insurance will be obtained instead. If required, the title insurance policy may include environmental protection lien endorsement coverage (ALTA Form 8.1 or its equivalent) excepting only Superliens which may arise after the loan is made. Mortgage loans on refinance transactions generally do not contain title insurance policies. Title searches are often performed on these refinance transactions in lieu of obtaining a title insurance policy. A title search is a limited search of a specified parcel of land summarizing information concerning current owner(s) and all judgments, mortgages, and tax obligations filed. Borrowers Protection Plan(R) ---------------------------- Bank of America's Borrowers Protection Plan(R) ("BPP") is a debt-cancellation contract between the borrower and Bank of America. This optional plan can cancel a borrower's monthly principal and interest payment for up to a total of twelve months if the borrower loses his or her job or becomes disabled. Additionally, the outstanding principal balance of a mortgage loan with BPP will be cancelled if the borrower dies as a result of an accident. While Bank of America will cancel payment of the principal, interest and BPP fees, the borrower will still be responsible for the payment of taxes and insurance. Bank of America will be obligated to pay to the applicable Trust any amounts cancelled due to BPP on a Mortgage Loan. The following three protection options are available in a BPP contract: (i) disability, involuntary unemployment and accidental death; (ii) involuntary unemployment and accidental death or (iii) disability and accidental death. The benefit period ranges from six to twelve months. A borrower may elect single (i.e., one borrower who is named in the mortgage note) or joint coverage (i.e., any two of the borrowers named in the mortgage note). BPP is only available on certain first-lien fixed-rate and adjustable-rate mortgage loan products and programs. The term of protection is the lesser of the loan term and ten years. Upon expiration, BPP is discontinued and the monthly BPP fee is no longer assessed. If the borrower has an active BPP claim prior to the expiration date, however, loan protection can extend beyond the expiration date. BPP is optional and the borrower's choice regarding BPP is not considered when evaluating the loan request. The borrower must select the BPP plan prior to loan closing.

Bank of America's "Stated Income Program" provides applicants the ability to request that income stated on the loan application not be verified. The Debt to Income Ratio calculation used by the underwriter to evaluate the applicant's capacity for the loan is based on income the applicant discloses on the application. Under the Stated Income Program, applicants who have steady employment and complex sources of income or rapidly expanding incomes may be eligible. The Stated Income Program is designed to meet the needs of applicants with a traditional credit history who meet the minimum Credit Score requirement of the program. A verbal verification of employment confirming the applicant's date of employment, job status and title is required. While income information is not provided, the applicant must continue to provide documentation of assets used for down payment, closing costs, and reserves on purchase transactions.

A verbal verification of employment information provided in the application, without reference to income, takes place under this program. While income information is not provided, the applicant must continue to provide documentation of his or her assets used for down payment, closing costs, and reserves on purchase transactions. Bank of America's "100% LTV Program" provides applicants the ability to obtain a mortgage loan with no down payment. The 100% LTV Program is only available if the primary borrower has a minimum Credit Score. The 100% LTV Program also permits Loan to Value Ratios of up to 103% (including closing costs and prepaid items in an amount up to 3% of the value of the mortgaged property). Under this program, Bank of America uses the Standard Documentation Process.

If you are purchasing any Offered Certificates at a premium, and specifically if you are purchasing interest only certificates, you should consider the risk that if principal payments on the applicable mortgage loans or, in the case of interest only certificates whose notional amount is based on some or all of the Premium Mortgage Loans, such Premium Mortgage Loans, occur at a rate faster than you expected, your yield may be lower than you expected. You must make your own decisions as to the appropriate prepayment assumptions to be used when purchasing any Offered Certificates. The applicable Senior Prepayment Percentage of the applicable Non-PO Percentage of all principal prepayments (excluding for this purpose, partial liquidations due to default, casualty, condemnation and the like) initially will be distributed to the classes of related Senior Certificates then entitled to receive principal prepayment distributions. This may result in all (or a disproportionate percentage) of those principal prepayments being distributed to such Senior Certificates and none (or less than their pro rata share) of such principal prepayments being distributed to holders of the related Subordinate Certificates during the periods of time described in the applicable definition of "Senior Prepayment Percentage." The timing of changes in the rate of prepayments may significantly affect the actual yield to you, even if the average rate of principal prepayments is consistent with your expectations. In general, the earlier the payment of principal of the related Mortgage Loans, the greater the effect on your yield to maturity. As a result, the effect on your yield of principal prepayments occurring at a rate higher (or lower) than the rate you anticipate during the period immediately following the issuance of the certificates will not be offset by a subsequent like reduction (or increase) in the rate of principal prepayments. Any Yield Maintenance Agreement The Trustee on behalf of the Trust may enter is Subject to Counterparty Risk: into one or more Yield Maintenance Agreements with one or more counterparties, for the benefit of certain Classes of Certificates. Each Yield Maintenance Agreement will require the applicable counterparty to make certain payments in certain circumstances. To the extent that payments on such Certificates depend in part on payments to be received by the Trustee under the related Yield Maintenance Agreement, the ability of the Trustee to make such payments on such Certificates will be subject to the credit risk of the applicable counterparty.

The Servicer will determine that a proposed advance is nonrecoverable when, in the good faith exercise of its servicing judgment, it believes the proposed advance would not be ultimately recoverable from the related mortgagor, related liquidation proceeds, or other recoveries in respect of the Mortgage Loan. Because of the priority of distributions, shortfalls resulting from delinquencies that are not covered by advances will be borne first by the related Subordinate Certificates (in reverse numerical order), and then by the related Senior Certificates. Net interest shortfalls will adversely affect the yields on the Offered Certificates. In addition, losses generally will be borne by the related Subordinate Certificates. As a result, the yields on the Offered Certificates will depend on the rate and timing of realized losses on the related Mortgage Loans. Credits Scores May Not Accurately The Sponsor generally uses Credit Scores as Predict the Likelihood of Default: part of its underwriting process. The attached collateral summary shows credit scores for the mortgagors obtained at the time of origination of their mortgage loans. A credit score purports only to be a measurement of the relative degree of risk a borrower represents to a lender, i.e., that a borrower with a higher score is statistically expected to be less likely to default in payment than a borrower with a lower score. In addition, it should be noted that credit scores were developed to indicate a level of default probability over a two-year period, which does not correspond to the life of most mortgage loans. Furthermore, credit scores were not developed specifically for use in connection with mortgage loans, but for consumer loans in general. Therefore, credit scores do not address particular mortgage loan characteristics that influence the probability of repayment by the borrower. Neither the Depositor nor the Sponsor makes any representations any mortgage loan or that a particular credit score should be relied upon as a basis for an expectation that a borrower will repay its mortgage loan according to its terms. Geographic Concentrations May At various times, certain geographic regions Increase Risk of Loss Due to will experience weaker economic conditions Adverse Economic Conditions and housing markets and, consequently, will or Natural Disasters: experience higher rates of delinquency and loss on mortgage loans generally. In addition, certain states have experienced natural disasters, including earthquakes, fires, floods and hurricanes, which may adversely affect property values. Although mortgaged properties located in certain identified flood zones will be required to be covered, to the maximum extent available, by flood insurance, no mortgaged properties will otherwise be required to be insured against earthquake damage or any other loss not covered by standard hazard insurance policies. Any concentration of mortgaged properties in a state or region may present unique risk considerations. See the tables entitled "Geographic Distribution of Mortgaged Properties of the Mortgage Loans" in the attached collateral summary for a listing of the locations and concentrations of the mortgaged properties.

The value of any mortgaged property generally will change over time from its value on the appraisal or sales date.

If the residential real estate market should experience an overall decline in property values large enough to cause the outstanding balances of the Mortgage Loans and any secondary financing on the related mortgaged properties to equal or exceed the value of the mortgaged properties, delinquencies, foreclosures and losses could be higher than those now generally experienced in the mortgage lending industry or in the Sponsor's prior securitizations involving the Depositor. In addition, adverse economic conditions and other factors (which may or may not affect real property values) may affect the mortgagors' timely payment of scheduled payments of principal and interest on the Mortgage Loans and, accordingly, the actual rates of delinquencies, foreclosures and losses with respect to the mortgage pool. These other factors could include excessive building resulting in an oversupply of housing in a particular area or a decrease in employment reducing the demand for housing in an area.

It is possible that the number of reservists and members of the National Guard placed on active duty status may remain at high levels for an extended time. To the extent that a member of the military, or a member of the armed forces reserves or National Guard who is called to active duty, is a mortgagor of a mortgage loan in the trust, the interest rate limitation of the Servicemembers Civil Relief Act, and any comparable state law, will apply. This may result in interest shortfalls on the Mortgage Loans in the trust, which will be borne by all classes of interest bearing Certificates and components. Neither the Sponsor nor the Depositor has taken any action to determine whether any of the Mortgage Loans would be affected by these interest rate limitations. The Certificates May Not Receive Any "Yield Maintenance Amount" for any Amounts Expected from any Yield Distribution Date is based on the related Maintenance Agreements: notional amount, which decreases for each Distribution Date during the life of the related Yield Maintenance Agreement. The notional amounts specified in the related Yield Maintenance Agreement for each Distribution Date were derived by using an assumed prepayment rate. The actual rates of prepayment on the applicable Mortgage Loans are likely to differ from the rates assumed. If prepayments on the applicable Mortgage Loans occur at a rate slower than the rates used in determining the notional amounts specified in the related Yield Maintenance Agreement, the Class Balance(s) of the applicable Certificates will be greater than the related notional amount for a Distribution Date. For any Distribution Date on which the notional amount is lower than the actual Class Balance(s) of the related Certificates, the Yield Maintenance Amount will be greater than the payment the Counterparty is required to make under the applicable Yield Maintenance Agreement for such Distribution Date and therefore, a holder of the related Certificate may not receive its full Yield Maintenance Amount for such Distribution Date. However, to the extent that a holder of a class of related Certificates does not receive the full Yield Maintenance Amount for a Distribution Date, such shortfall may be paid to the related class of Certificates from amounts in the related Reserve Fund on future Distribution Dates, to the extent funds are available therefore.

This may result in a shortfall in interest collections available for payment on the next Distribution Date. The Servicer is required to cover a portion of the shortfall in interest collections that are attributable to prepayments in full and partial prepayments on the Mortgage Loans, but in each case only up to the amount of Compensating Interest related to such Mortgage Loans for such Distribution Date.

The Certificates do not represent an interest in or obligation of the Depositor, the Servicer, the Sponsor, the Trustee or any of their affiliates. There are, however, limited obligations of the Depositor with respect to certain breaches of representations and warranties, and limited obligations of the Servicer with respect to its servicing obligations. Neither the Certificates nor the Mortgage Loans will be guaranteed by or insured by any governmental agency or instrumentality, the Depositor, the Sponsor, the Servicer, the Trustee or any of their affiliates. Consequently, if payments on the Mortgage Loans are insufficient or otherwise unavailable to make all payments required on the Certificates, there will be no recourse to the Depositor, the Sponsor, the Servicer, the Trustee or any of their affiliates. Limited Liquidity: The Underwriter intends to make a market for purchase and sale of the Offered Certificates after their initial issuance, but the Underwriter has no obligation to do so. There is no assurance that such a secondary market will develop or, if it does develop, that it will provide you with liquidity of investment or that it will continue for the life of the Offered Certificates. As a result, you may not be able to sell your Certificates or you may not be able to sell your Certificates at a high enough price to produce your desired return on investment. The secondary market for mortgage-backed securities has experienced periods of illiquidity and can be expected to do so in the future. Illiquidity means that there may not be any purchasers for your class of Certificates. Although any class of Certificates may experience illiquidity, it is more likely that classes of Certificates that are more sensitive to prepayment, credit or interest rate risk (such as the Interest Only, Super Senior Support, Companion, Inverse Floating Rate, Principal Only, or Subordinated Certificates) will experience illiquidity. Alternative Underwriting Certain of the Mortgage Loans may have been Standards May Increase Risk originated using the Sponsor's "Alternative of Loss: A" underwriting guidelines. See "Underwriting Guidelines of Bank of America--Bank of America Alternative Underwriting Standards" above. These underwriting guidelines are different from and, in certain respects, less stringent than the general underwriting guidelines employed by the sponsor. For example, certain of the mortgage loans may have been originated with less than standard documentation or with higher maximum loan-to-value ratios. Accordingly, the mortgage loans may experience rates of delinquencies, defaults, foreclosure, bankruptcy and loss that are higher than those experienced by mortgage loans underwritten using the Sponsor's general underwriting standards.

An investor property Properties May be Higher than on is a property which, at the time of Other Mortgage Loans: origination, the mortgagor represented would not be used as the mortgagor's primary residence or second home. Because the mortgagor is not living on the property, the mortgagor may be more likely to default on the mortgage loan than on a comparable mortgage loan secured by a primary residence, or to a lesser extent, a second home. In addition, income expected to be generated from an investor property may have been considered for underwriting purposes in addition to the income of the mortgagor from other sources. Should this income not materialize, it is possible the mortgagor would not have sufficient resources to make payments on the mortgage loan. There Are Risks Relating to At the time of origination of certain of the Mortgaged Properties Subject to Mortgage Loans, a lender other than the Second Lien Mortgage Sponsor may have originated a second lien Loans: mortgage loan. Mortgage Loans that have second lien mortgage loans encumbering the same mortgaged property may have higher rates of delinquency and foreclosure relative to mortgage loans that do not have second lien mortgage loans behind them. This may be due to changes in the mortgagor's debt-to-income profile, the fact that mortgagors may then have less equity in the mortgaged property or other factors. You should also note that any mortgagor could obtain a second lien mortgage loan at any time subsequent to the date of origination of their first lien mortgage loan from any lender. Subordinate Certificates May The Subordinate Certificates may provide Provide Subordination for credit support for more than one Groups of All Groups Senior Certificates and thus the outstanding Class Balances of such Subordinate Certificates could be reduced to zero as a result of a disproportionate amount of principal losses on the Mortgage Loans in one Loan Group. Therefore, these losses on the Mortgage Loans in one Loan Group will reduce the subordination provided by the Subordinate Certificates to the other Groups of Senior Certificates and increase the likelihood that losses may be allocated to the other Groups of Senior Certificates. Under certain circumstances due to a cross-collateralization mechanism, principal otherwise payable to these Subordinate Certificates will be paid to certain Senior Certificates.

The Classes, in general, fall into different categories. The following chart identifies and generally defines certain of the more typical categories. The prospectus supplement for a series of Certificates may identify the Classes which comprise that series by reference to the following categories or another category specified in the prospectus supplement. PRINCIPAL TYPES --------------- Categories of Classes ............ Definitions Accretion Directed Certificates .................. A Class of Certificates that receives principal payments from amounts that would otherwise be distributed as interest on specified Accrual Certificates. These principal payments may be in lieu of or in addition to principal payments from principal receipts on the Mortgage Loans for the related series. Companion Certificates (also sometimes referred to as "Support Certificates") ....... A Class of Certificates that is entitled to receive principal payments on any Distribution Date only if scheduled payments have been made on specified Planned Amortization Certificates, Targeted Amortization Certificates and/or Scheduled Amortization Certificates. Component Certificates ........... A Class of Certificates consisting of two or more specified components (each, a "Component"), as described in the applicable prospectus supplement. The Components of a Class of Component Certificates may have different principal and/or interest payment characteristics but together constitute a single class and do not represent severable interests. Each Component of a Class of Component Certificates may be identified as falling into one or more of the categories in this chart. Lockout Certificates ............. A Class of Senior Certificates that is designed not to participate in or to participate to a limited extent in (i.e., to be "locked out" of ), for a specified period, the receipt of (1) principal prepayments on the Mortgage Loans that are allocated disproportionately to the Classes of Senior Certificates of its series as a group pursuant to a "shifting interest" structure and/or (2) scheduled principal payments on the Mortgage Loans that are allocated to the senior Classes as a group. A Class of Lockout Certificates will typically not be entitled to receive, or will be entitled to receive only a restricted portion of, distributions of principal prepayments and/or scheduled principal prepayments, as applicable, for a period of several years, during which time all or a portion of the principal payments that it would otherwise be entitled to receive in the absence of a "lockout" structure will be distributed in reduction of the Class Balances of other Senior Certificates. Lockout Certificates are designed to minimize weighted average life volatility during the lockout period.

A Class of Certificates having no Class Balance and bearing interest on a notional amount. The notional amount is a hypothetical balance used for calculating interest distributions. Pass-Through Certificates ........ A Class of Senior Certificates that is entitled to receive a specified percentage of the principal payments that are distributable to the Senior Certificates or applicable group of Senior Certificates (other than any Ratio Strip Certificates) in the aggregate on a Distribution Date and that is not designated as a Class of Sequential Pay Certificates. Planned Amortization Certificates (also sometimes referred to as "PAC Certificates") ................ A Class of Certificates that is designed to receive principal payments using a predetermined principal balance schedule derived by assuming two constant prepayment rates for the underlying Mortgage Loans. These two rates are the endpoints for the "structuring range" for a Class of Planned Amortization Certificates. The Classes of Planned Amortization Certificates in any series may be subdivided into different categories (e.g., Planned Amortization I Certificates or PAC I Certificates, Planned Amortization II Certificates or PAC II Certificates and so forth) derived using different structuring ranges and/or payment priorities. A Class of PAC Certificates is designed to provide protection against prepayments occurring at a constant rate within the structuring range. Ratio Strip Certificates ......... A Class of Certificates that is entitled to receive a constant proportion, or "ratio strip," of the principal payments on the underlying Mortgage Loans. Scheduled Amortization Certificates .................. A Class of Certificates that is designed to receive principal payments using a predetermined principal balance schedule but is not designated as a Class of Planned Amortization Certificates or Targeted Amortization Certificates. The schedule is derived by assuming either two constant prepayment rates or a single constant prepayment rate for the underlying Mortgage Loans. In the former case, the two rates are the endpoints for the "structuring range" for a Class of Scheduled Amortization Certificates and the range generally is narrower than that for a Class of Planned Amortization Certificates. Typically, the Companion Certificates for the applicable series of Certificates generally will represent a smaller percentage of a Class of Scheduled Amortization Certificates than the Companion Certificates generally would represent in relation to a Class of Planned Amortization Certificates or Targeted Amortization Certificates. A Class of Scheduled Amortization Certificates is generally less sensitive to prepayments than a Class of Companion Certificates, but more sensitive than a Class of Planned Amortization Certificates or Targeted Amortization Certificates.

A Class of Certificates that is entitled to receive payments of principal and interest on each Distribution Date prior to the Classes of Subordinate Certificates. Sequential Pay Certificates ...... Classes of Certificates that are entitled to receive principal payments in a prescribed sequence, that do not have predetermined principal balance schedules and that, in most cases, are entitled to receive payments of principal continuously from the first Distribution Date on which they receive principal until they are retired. A Class of Sequential Pay Certificates may receive principal payments concurrently with one or more other Classes of Sequential Pay Certificates. Subordinate Certificates ......... A Class of Certificates that is entitled to receive payments of principal and interest on each Distribution Date only after the Senior Certificates and Classes of Subordinate Certificates with higher priority of distributions have received their full principal and interest entitlements. Super Senior Certificates ........ A Class of Senior Certificates that will not bear its share of certain losses after the Classes of Subordinate Certificates are no longer outstanding for so long as one or more specified Classes of Senior Certificates are outstanding. Super Senior Support Certificates .................. A Class of Senior Certificates that bears certain losses allocated to one or more Classes of Super Senior Certificates. Targeted Amortization Certificates (also sometimes referred to as "TAC Certificates") ................ A Class of Certificates that is designed to receive principal payments using a predetermined principal balance schedule derived by assuming a single constant prepayment rate for the underlying Mortgage Loans. A Class of TAC Certificates is designed to provide some protection against prepayments at a rate exceeding the assumed constant prepayment rate used to derive that Class's principal balance schedule. Special Retail Certificates....... Although there can be no assurance as to the rate at which principal distributions will be made on any class of Offered Certificates, special retail certificates, in particular, may be inappropriate investments for you if you require a distribution of a particular amount of principal on a specific date or an otherwise predictable stream of distributions. If you own special retail certificates, funds available for distributions of principal may not be sufficient to permit the distributions you request within any specific period of time after your request. During periods in which prevailing interest rates are generally higher than the pass-through rate for a class of special retail certificates, greater numbers of beneficial owners may request distributions of principal in respect of the special retail certificates to take advantage of higher interest rates. During such periods there may, however, be a concurrent reduction in the rate of prepayments of the related Mortgage Loans, thus limiting the funds available for such distributions.

It is more likely that amounts will be distributed by random lot during the periods of the relatively low interest rates and, correspondingly, higher prepayment rates. Under such circumstances you may have difficulty reinvesting these principal distributions at rates as high as the pass-through rate of your Certificates or your expected yield. INTEREST TYPES -------------- Categories of Class .............. Definitions Accrual Certificates ............. A Class of Certificates that accretes the amount of accrued interest otherwise distributable on that Class, which amount will be added as principal to the Class Balance of that Class on each applicable Distribution Date. This accretion may continue until some specified event has occurred or until the Class of Accrual Certificates is retired. Fixed Rate Certificates .......... A Class of Certificates with an interest rate that is fixed throughout the life of the Class. Floating Rate Certificates ....... A Class of Certificates with an interest rate that resets periodically based upon a designated index and that varies directly with changes in that index. Interest Only Certificates ....... A Class of Certificates that is entitled to receive some or all of the interest payments made on the Mortgage Loans and little or no principal. Interest Only Certificates have either a nominal Class Balance or a notional amount. A nominal Class Balance represents actual principal that will be paid on the Class. It is referred to as nominal since it is extremely small compared to other Classes. A notional amount is the amount used as a reference to calculate the amount of interest due on a Class of Interest Only Certificates that is not entitled to any distributions in respect of principal. Inverse Floating Rate Certificates .................. A Class of Certificates with an interest rate that resets periodically based upon a designated index and that varies inversely with changes in that index and with changes in the interest rate payable on the related Class of Floating Rate Certificates. Principal Only Certificates ...... A Class of Certificates that does not bear interest and is entitled to receive only distributions of principal.
