The actual remaining terms to maturity, weighted average loan ages and interest rates of most ofthe mortgage loans will diÅer from the weighted averages shown above, perhaps signiÑcantly.

Class Factors

The class factors are numbers that, when multiplied by the initial principal balance of acertiÑcate, can be used to calculate the current principal balance of that certiÑcate (after taking intoaccount principal payments in the same month). We publish the class factors on or shortly after the11th day of each month.

S-4

Settlement Date

We expect to issue the certiÑcates on March 28, 2003.

Distribution Dates

We will make payments on the certiÑcates on the 25th day of each calendar month, or on the nextbusiness day if the 25th day is not a business day.

Book-Entry and Physical CertiÑcates

We will issue the book-entry certiÑcates through the U.S. Federal Reserve Banks, which willelectronically track ownership of the certiÑcates and payments on them. We will issue physicalcertiÑcates in registered, certiÑcated form.

We will issue the classes of certiÑcates in the following forms:

Fed Book-Entry Physical

All classes of certiÑcates other R and RL Classesthan the R and RL Classes

Exchanging CertiÑcates Through Combination and Recombination

If you own certain certiÑcates, you will be able to exchange them for a proportionate interest inthe related RCR certiÑcates as shown on Schedule 1. We will issue the RCR certiÑcates upon suchexchange. You can exchange your certiÑcates by notifying us and paying an exchange fee. We use theprincipal and interest of the certiÑcates exchanged to pay principal and interest on the related RCRcertiÑcates. Schedule 1 lists the available combinations of the certiÑcates eligible for exchange and therelated RCR certiÑcates.

Interest Rates

During each interest accrual period, the Ñxed rate classes will bear interest at the applicableannual interest rates listed on the cover of this prospectus supplement or on Schedule 1.

During the initial interest accrual period, the Öoating rate and inverse Öoating rate classes willbear interest at the initial interest rates listed below. During subsequent interest accrual periods, theÖoating rate and inverse Öoating rate classes will bear interest based on the formulas indicated below,but always subject to the speciÑed maximum and minimum interest rates:

DESCRIPTION OF THE CERTIFICATES

The material under this heading summarizes certain features of the CertiÑcates. You will Ñndadditional information about the CertiÑcates in the other sections of this prospectus supplement, aswell as in the additional Disclosure Documents and the Trust Agreement. If we use a capitalized termin this prospectus supplement without deÑning it, you will Ñnd the deÑnition of that term in theapplicable Disclosure Document or in the Trust Agreement.

General

Structure. We will create the Fannie Mae REMIC Trust speciÑed on the cover of thisprospectus supplement (the ""Trust'') and a separate trust (the ""Lower Tier REMIC'') pursuant to atrust agreement dated as of March 1, 2003 (the ""Issue Date''). We will issue the Guaranteed REMICPass-Through CertiÑcates (the ""REMIC CertiÑcates'') pursuant to that trust agreement. We willissue the Combinable and Recombinable REMIC CertiÑcates (the ""RCR CertiÑcates'' and, togetherwith the REMIC CertiÑcates, the ""CertiÑcates'') pursuant to a separate trust agreement dated as ofthe Issue Date (together with the trust agreement relating to the REMIC CertiÑcates, the ""TrustAgreement''). We will execute the Trust Agreement in our corporate capacity and as trustee (the""Trustee''). In general, the term ""Classes'' includes the Classes of REMIC CertiÑcates and RCRCertiÑcates.

The Trust and the Lower Tier REMIC each will constitute a ""real estate mortgage investmentconduit'' (""REMIC'') under the Internal Revenue Code of 1986, as amended (the ""Code'').

‚ The REMIC CertiÑcates (except the R and RL Classes) will be ""regular interests'' in theTrust.

‚ The R Class will be the ""residual interest'' in the Trust.

‚ The interests in the Lower Tier REMIC other than the RL Class (the ""Lower Tier RegularInterests'') will be the ""regular interests'' in the Lower Tier REMIC.

‚ The RL Class will be the ""residual interest'' in the Lower Tier REMIC.

The assets of the Trust will consist of the Lower Tier Regular Interests.

The assets of the Lower Tier REMIC will consist of

‚ certain previously issued REMIC certiÑcates (the ""Group 1 Underlying REMIC CertiÑcates'')evidencing beneÑcial ownership interests in the related Fannie Mae REMIC trust (the""Underlying REMIC Trust''), all as further described in Exhibit A, and

‚ seven groups of Fannie Mae Guaranteed Mortgage Pass-Through CertiÑcates (the ""Group 2MBS,'' ""Group 3 MBS,'' ""Group 4 MBS,'' ""Group 5 MBS,'' ""Group 6 MBS,'' ""Group 7 MBS''and ""Group 8 MBS'' and, together, the ""Trust MBS'').

S-12

The assets of the Underlying REMIC Trust evidence direct or indirect beneÑcial ownershipinterests in certain MBS.

Each MBS represents a beneÑcial ownership interest in a pool of Ñrst lien, one- to four-family(""single-family''), Ñxed-rate residential mortgage loans (the ""Mortgage Loans'') having the charac-teristics described in this prospectus supplement.

Fannie Mae Guaranty. We guarantee that we will distribute to CertiÑcateholders:

‚ required installments of principal and interest on the CertiÑcates on time, and

‚ the principal balance of each Class of CertiÑcates no later than its Final Distribution Date,whether or not we have received suÇcient payments on the MBS.

In addition, we guarantee that we will distribute to each holder of an MBS:

‚ scheduled installments of principal and interest on the underlying Mortgage Loans on time,whether or not the related borrowers pay us, and

‚ the full principal balance of any foreclosed Mortgage Loan, whether or not we recover it.

Our guaranty obligations with respect to the Group 1 Underlying REMIC CertiÑcates are described inthe Underlying REMIC Disclosure Document. Our guarantees are not backed by the full faith andcredit of the United States. See ""Description of the CertiÑcatesÌThe Fannie Mae Guaranty'' in theREMIC Prospectus, ""Description of the CertiÑcatesÌFannie Mae Guaranty'' in the MBS Prospectus,and ""Description of the CertiÑcatesÌGeneralÌFannie Mae Guaranty'' in the Underlying REMICDisclosure Document.

Characteristics of CertiÑcates. We will issue the CertiÑcates (except the R and RL Classes) inbook-entry form on the book-entry system of the U.S. Federal Reserve Banks (the ""Fed Book-EntryCertiÑcates''). Entities whose names appear on the book-entry records of a Federal Reserve Bank ashaving had CertiÑcates deposited in their accounts are ""Holders'' or ""CertiÑcateholders.'' A Holder isnot necessarily the beneÑcial owner of a CertiÑcate. BeneÑcial owners ordinarily will hold CertiÑcatesthrough one or more Ñnancial intermediaries, such as banks, brokerage Ñrms and securities clearingorganizations. See ""Description of CertiÑcatesÌDenominations and Form'' in the REMICProspectus.

We will issue the R and RL CertiÑcates in fully registered, certiÑcated form. The ""Holder'' or""CertiÑcateholder'' of the R or RL CertiÑcate is its registered owner. The R or RL CertiÑcate can betransferred at the corporate trust oÇce of the Transfer Agent, or at the oÇce of the Transfer Agent inNew York, New York. U.S. Bank National Association (""US Bank'') in Boston, Massachusetts will bethe initial Transfer Agent. We may impose a service charge for any registration of transfer of the R orRL CertiÑcate and may require payment to cover any tax or other governmental charge. See also ""ÌCharacteristics of the R and RL Classes'' below.

The Holder of the R Class will receive the proceeds of any remaining assets of the Trust, and theHolder of the RL Class will receive the proceeds of any remaining assets of the Lower Tier REMIC, ineach case only by presenting and surrendering the related CertiÑcate at the oÇce of the Paying Agent.US Bank will be the initial Paying Agent.

Authorized Denominations. We will issue the CertiÑcates, other than the R and RL Classes, inminimum denominations of $1,000 and whole dollar increments. We will issue the R and RL Classesas single CertiÑcates with no principal balances.

Distribution Dates. We will make monthly payments on the CertiÑcates on the 25th day of eachmonth (or, if the 25th is not a business day, on the Ñrst business day after the 25th). We refer to eachof these dates as a ""Distribution Date.'' We will make the Ñrst payments to CertiÑcateholders themonth after we issue the CertiÑcates.

S-13

Record Date. On each Distribution Date, we will make each monthly payment on the CertiÑ-cates to Holders of record on the last day of the preceding month.

Class Factors. On or shortly after the eleventh calendar day of each month, we will publish afactor (carried to eight decimal places) for each Class of CertiÑcates. When the applicable class factoris multiplied by the original principal balance (or notional principal balance) of a CertiÑcate of anyClass, the product will equal the current principal balance (or notional principal balance) of thatCertiÑcate after taking into account payments on the Distribution Date in the same month (as well asany addition to principal in the case of the Accrual Classes).

No Optional Termination. We have no option to eÅect an early termination of the Lower TierREMIC or the Trust. Further, we will not repurchase the Mortgage Loans underlying any MBS in a""clean-up call.'' See ""Description of the CertiÑcatesÌTermination'' in the MBS Prospectus.

Voting the Group 1 Underlying REMIC CertiÑcates. Holders of the Group 1 Underlying REMICCertiÑcates may be asked to vote on issues arising under the related trust agreement. If so, the Trusteewill vote the Group 1 Underlying REMIC CertiÑcates as instructed by Holders of CertiÑcates of theClasses backed by the Group 1 Underlying REMIC CertiÑcates. The Trustee must receive instructionsfrom Holders of CertiÑcates having principal balances totaling at least 51% of the aggregate principalbalance of the related Classes. In the absence of such instructions, the Trustee will vote in a mannerconsistent, in its sole judgment, with the best interests of CertiÑcateholders.

Combination and Recombination

General. You are permitted to exchange all or a portion of the WI, WE, WG, WH, WJ, IW, WB,NI, TI, KE, IM, MA, IK, MB, ID and BD Classes of REMIC CertiÑcates for a proportionate interestin the related RCR CertiÑcates in the combinations shown on Schedule 1. You also may exchange allor a portion of the RCR CertiÑcates for the related REMIC CertiÑcates in the same manner. Thisprocess may occur repeatedly.

Holders of RCR CertiÑcates will be the beneÑcial owners of a proportionate interest in the relatedREMIC CertiÑcates and will receive a proportionate share of the distributions on the related REMICCertiÑcates.

The Classes of REMIC CertiÑcates and RCR CertiÑcates that are outstanding at any given time,and the outstanding principal balances (or notional principal balances) of these Classes, will dependupon any related distributions of principal, as well as any exchanges that occur. REMIC CertiÑcatesand RCR CertiÑcates may be exchanged only in the proportions shown on Schedule 1.

Procedures. If a CertiÑcateholder wishes to exchange CertiÑcates, the CertiÑcateholder mustnotify our Structured Transactions Department through one of our ""REMIC Dealer Group'' dealers inwriting or by telefax no later than two business days before the proposed exchange date. The exchangedate can be any business day other than the Ñrst or last business day of the month subject to ourapproval. The notice must include the outstanding principal balance of both the CertiÑcates to beexchanged and the CertiÑcates to be received, and the proposed exchange date. After receiving theHolder's notice, we will telephone the dealer with delivery and wire payment instructions. Noticebecomes irrevocable on the second business day before the proposed exchange date.

In connection with each exchange, the Holder must pay us a fee equal to 1/32 of 1% of theoutstanding principal balance (exclusive of any notional principal balance) of the CertiÑcates to beexchanged. In no event, however, will our fee be less than $2,000.

We will make the Ñrst distribution on a REMIC CertiÑcate or an RCR CertiÑcate received in anexchange transaction on the Distribution Date in the following month. We will make that distributionto the Holder of record as of the close of business on the last day of the month of the exchange.

Additional Considerations. The characteristics of RCR CertiÑcates will reÖect the characteris-tics of the REMIC CertiÑcates used to form those RCR CertiÑcates. You should also consider a

S-14

number of factors that will limit a CertiÑcateholder's ability to exchange REMIC CertiÑcates for RCRCertiÑcates or vice versa:

‚ At the time of the proposed exchange, a CertiÑcateholder must own CertiÑcates of the relatedClass or Classes in the proportions necessary to make the desired exchange.

‚ A CertiÑcateholder that does not own the CertiÑcates may be unable to obtain the necessaryREMIC CertiÑcates or RCR CertiÑcates.

‚ The CertiÑcateholder of needed CertiÑcates may refuse to sell them at a reasonable price (orany price) or may be unable to sell them.

‚ Certain CertiÑcates may have been purchased and placed into other Ñnancial structures andthus be unavailable.

‚ Principal distributions will decrease the amounts available for exchange over time.

‚ Only the combinations listed on Schedule 1 are permitted.

The Group 1 Underlying REMIC CertiÑcates

The Group 1 Underlying REMIC CertiÑcates represent beneÑcial ownership interests in theUnderlying REMIC Trust. The assets of that trust evidence direct or indirect beneÑcial ownershipinterests in certain MBS having the general characteristics set forth in the MBS Prospectus.Distributions on the Group 1 Underlying REMIC CertiÑcates will be passed through monthly,beginning in the month after we issue the CertiÑcates. The general characteristics of the Group 1Underlying REMIC CertiÑcates are described in the Underlying REMIC Disclosure Document.

These may include changesin prepayment speeds, prevailing interest rates and other economic factors. As a result, the usefulnessof the information set forth in those documents may be limited.

The Trust MBS

The following table contains certain information about the Trust MBS. The Trust MBS includedin each speciÑed Group will have the aggregate unpaid principal balance and Pass-Through Rateshown below and the general characteristics described in the MBS Prospectus. The Trust MBSprovides that principal and interest on the related Mortgage Loans are passed through monthly. TheMortgage Loans underlying the Trust MBS are conventional, Ñxed-rate, fully-amortizing mortgageloans secured by Ñrst mortgages or deeds of trust on single-family residential properties. TheseMortgage Loans have original maturities of up to 30 years in the case of the Group 2, Group 3 andGroup 5 MBS, up to 15 years in the case of the Group 4, Group 7 and Group 8 MBS, and up to 20years in the case of the Group 6 MBS.

General. We will pay interest on the CertiÑcates at the applicable annual interest rates speciÑedon the cover or described in this prospectus supplement. We calculate interest based on an assumed360-day year consisting of twelve 30-day months. We pay interest monthly (except in the case of theAccrual Classes) on each Distribution Date, beginning in the month after the Settlement DatespeciÑed in the Reference Sheet.

Interest to be paid on each CertiÑcate (or added to principal, in the case of the Accrual Classes)on a Distribution Date will consist of one month's interest on the outstanding balance of thatCertiÑcate immediately prior to that Distribution Date. For a description of the Accrual Classes, see""ÌAccrual Classes'' below.

We will apply interest payments from exchanged REMIC CertiÑcates to the corresponding RCRCertiÑcates, on a pro rata basis, following any exchange.

Interest Accrual Periods. Interest to be paid on each Distribution Date will accrue on theCertiÑcates during the applicable one-month periods set forth below (each, an ""Interest AccrualPeriod'').

Classes Interest Accrual Periods

in which the Distribution Date occurs

See ""Additional Risk FactorsÌDelay classes have lower yields and market values'' in this prospectussupplement.

Accrual Classes. The ZL and WZ Classes are Accrual Classes. Interest will accrue on the AccrualClass at the applicable annual rate speciÑed on the cover of this prospectus supplement. However, wewill not pay any interest on the Accrual Class. Instead, interest accrued on the Accrual Class will beadded as principal to its principal balance on each Distribution Date. We will pay principal on theAccrual Class as described under ""ÌDistributions of Principal'' below.

Notional Classes. The Notional Classes will not have principal balances. During each InterestAccrual Period, the Notional Classes will bear interest on their notional principal balances at theirapplicable interest rates. The notional principal balances of the Notional Classes will be calculated asspeciÑed under ""Reference SheetÌNotional Classes'' in this prospectus supplement.

We use the notional principal balance of a Notional Class to determine interest payments on thatClass. Although a Notional Class will not have a principal balance and will not be entitled to any

S-18

principal payments, we will publish a class factor for that Class. References in this prospectussupplement to the principal balances of the CertiÑcates generally shall refer also to the notionalprincipal balances of the Notional Classes.

Floating Rate and Inverse Floating Rate Classes. During each Interest Accrual Period, theFloating Rate and Inverse Floating Rate Classes will bear interest at rates determined as describedunder ""Reference SheetÌInterest Rates'' in this prospectus supplement.

Changes in the speciÑed interest rate index (the ""Index'') will aÅect the yields with respect to therelated Classes. These changes may not correspond to changes in mortgage interest rates. Lowermortgage interest rates could occur while an increase in the level of the Index occurs. Similarly, highermortgage interest rates could occur while a decrease in the level of the Index occurs.

Our establishment of each Index value and our determination of the interest rate for eachapplicable Class for the related Interest Accrual Period will be Ñnal and binding in the absence ofmanifest error. You may obtain each such interest rate by telephoning us at 1-800-237-8627 or202-752-6547.

Calculation of LIBOR

On each Index Determination Date, we will calculate LIBOR for the related Interest AccrualPeriod. We will calculate LIBOR on the basis of the ""BBA Method,'' as described in the REMICProspectus under ""Description of CertiÑcatesÌIndexes for Floating Rate Classes and InverseFloating Rate ClassesÌLIBOR.''

If we are unable to calculate LIBOR on the initial Index Determination Date, LIBOR for thefollowing Interest Accrual Period will be equal to 2.00% in the case of the GF, GS and GT Classes and1.34% in the case of all other Floating Rate and Inverse Floating Rate Classes.

Structuring Assumptions

Pricing Assumptions. Except where otherwise noted, the information in the tables in thisprospectus supplement has been prepared based on the actual characteristics of each pool of Mortgage

S-25

Loans backing the Group 1 Underlying REMIC CertiÑcates and the following assumptions (suchcharacteristics and assumptions, collectively, the ""Pricing Assumptions''):

‚ the Mortgage Loans underlying the Trust MBS have the original terms to maturity, remainingterms to maturity, WALAs and interest rates speciÑed under ""Reference SheetÌAssumedCharacteristics of the Mortgage Loans Underlying the Trust MBS'' in this prospectussupplement;

‚ the Mortgage Loans prepay at the constant percentages of PSA speciÑed in the related table;

‚ the settlement date for the sale of the CertiÑcates is March 28, 2003; and

‚ each Distribution Date occurs on the 25th day of a month.

Prepayment Assumptions. Prepayments of mortgage loans commonly are measured relative to aprepayment standard or model. The model used in this prospectus supplement with respect to allClasses and Principal Balances Schedules (other than the Group 1 MBS SpeciÑed Balances) is TheBond Market Association's standard prepayment model (""PSA''). To assume a speciÑed rate of PSAis to assume a speciÑed rate of prepayment each month of the then-outstanding principal balance of apool of new mortgage loans computed as described under ""Description of CertiÑcatesÌPrepaymentModels'' in the REMIC Prospectus.

The model used in this prospectus supplement with respect to the Group 1 MBS SpeciÑedBalances is the constant prepayment rate model (""CPR''). CPR represents the annual rate ofprepayment relative to the then outstanding principal balance of a pool of new mortgage loans. Thus,""0% CPR'' means no prepayments, ""15% CPR'' means an annual prepayment rate of 15%, and soforth.

It is highly unlikely that prepayments will occur at any constant PSA or CPR rate, as applicable,or at any other constant rate.

Structuring Ranges and Rates. The Principal Balance Schedules are found beginning onpage B-1 of this prospectus supplement. The Principal Balance Schedules have been prepared on thebasis of the Pricing Assumptions and the assumption that the related Mortgage Loans will prepay at aconstant PSA rate within the applicable Structuring Ranges or at the applicable PSA or CPR rates setforth below.

Principal BalanceSchedule References Related Groups(1) Structuring Ranges and Rates

Scheduled Balances QX Class Between 130% and 200% PSAPlanned Balances Aggregate Group I Between 150% and 700% PSASpeciÑed Balances Group 1 MBS 14% CPRSpeciÑed Balances Group 3 MBS 210% PSAPlanned Balances Aggregate Group II Between 100% and 250% PSAPlanned Balances Aggregate Group III Between 100% and 250% PSAScheduled Balances Aggregate Group IV Between 125% and 200% PSA

(1) The Structuring Ranges for the Aggregate Groups are associated with the related Aggregate Balances but not with theindividual balances of the related Classes.

We cannot assure you that the balance of any Group or Class listed above will conformon any Distribution Date to the speciÑed balance in the Principal Balance Schedules. As aresult, we cannot assure you that payments of principal of any Group or Class listed abovewill begin or end on the Distribution Dates speciÑed in the Principal Balance Schedules. Wewill distribute any excess of principal payments over the amount needed to reduce a Group or Class toits scheduled balance on a Distribution Date. Accordingly, the ability to reduce a Group or Class to itsscheduled balance will not be improved by the averaging of high and low principal payments frommonth to month. In addition, even if the related Mortgage Loans prepay at rates falling within theapplicable Structuring Ranges, principal distributions may be insuÇcient to reduce the applicableGroup or Class to their scheduled balances if the prepayments do not occur at a constant PSA rate, as

S-26

applicable. Moreover, because of the diverse remaining terms to maturity of the related MortgageLoans, which may include recently originated Mortgage Loans, the Groups or Class speciÑed abovemay not be reduced to their scheduled balances, even if prepayments occur at a constant rate withinthe applicable Structuring Ranges.

Initial EÅective Ranges. The EÅective Range for a Group or Class is the range of prepaymentrates (measured by constant PSA rates) which would reduce that Group or Class to its scheduledbalance on each Distribution Date. The Initial EÅective Ranges shown in the table below are basedupon the assumed characteristics of the related Mortgage Loans speciÑed in the Pricing Assumptions.

Groups Initial EÅective Ranges

QX Class Between 130% and 200%Aggregate Group I Between 150% and 700%Aggregate Group II Between 100% and 250%Aggregate Group III Between 100% and 250%Aggregate Group IV Between 125% and 200%

The actual EÅective Ranges at any time will be based upon the actual characteristics of therelated Mortgage Loans at that time, which are likely to vary (and may vary considerably) from thePricing Assumptions. The actual EÅective Ranges calculated on the basis of the actual characteristicsare likely to diÅer from the Initial EÅective Ranges. As a result, the applicable Groups or Class mightnot be reduced to their scheduled balances even if prepayments were to occur at a constant PSA ratewithin the Initial EÅective Ranges. This is so particularly if the rate were at the lower or higher end ofthis range. In addition, even if prepayments occur at rates falling within the actual EÅective Ranges,principal distributions may be insuÇcient to reduce the applicable Groups or Class to their scheduledbalances if such prepayments do not occur at a constant PSA rate. It is highly unlikely that the relatedMortgage Loans will prepay at any constant PSA rate. In general, the actual EÅective Ranges maynarrow, widen or shift upward or downward to reÖect actual prepayment experience over time. Thestability in principal payment of the PAC and Scheduled Groups and Scheduled Class will besupported in part by the related Support Groups and Classes. When the related Support Group andClasses are retired, the PAC and Scheduled Groups and Scheduled Class, if still outstanding, may nolonger have EÅective Ranges and will be more sensitive to prepayments.

Yield Tables

General. The tables below illustrate the sensitivity of the pre-tax corporate bond equivalentyields to maturity of the applicable Classes to various constant percentages of PSA and, wherespeciÑed, to changes in the Index. We calculated the yields set forth in the tables by

‚ determining the monthly discount rates that, when applied to the assumed streams of cashÖows to be paid on the applicable Classes, would cause the discounted present values of theassumed streams of cash Öows to equal the assumed aggregate purchase prices of those Classes,and

‚ converting the monthly rates to corporate bond equivalent rates.

These calculations do not take into account variations in the interest rates at which you could reinvestdistributions on the CertiÑcates. Accordingly, these calculations do not illustrate the return on anyinvestment in the CertiÑcates when reinvestment rates are taken into account.

We cannot assure you that

‚ the pre-tax yields on the applicable CertiÑcates will correspond to any of the pre-tax yieldsshown here, or

‚ the aggregate purchase prices of the applicable CertiÑcates will be as assumed.

S-27

In addition, it is unlikely that the Index will correspond to the levels shown here. Furthermore,because some of the Mortgage Loans are likely to have remaining terms to maturity shorter or longerthan those assumed and interest rates higher or lower than those assumed, the principal payments onthe CertiÑcates are likely to diÅer from those assumed. This would be the case even if all MortgageLoans prepay at the indicated constant percentages of PSA. Moreover, it is unlikely that

‚ the Mortgage Loans will prepay at a constant PSA rate until maturity,

‚ all of the Mortgage Loans will prepay at the same rate, or

‚ the level of the Index will remain constant.

The Fixed Rate Interest Only Classes. The yields to investors in the Fixed Rate InterestOnly Classes will be very sensitive to the rate of principal payments (including prepay-ments) of the related Mortgage Loans. The Mortgage Loans generally can be prepaid atany time without penalty.

The Inverse Floating Rate Classes. The yields on the Inverse Floating Rate Classes will besensitive in varying degrees to the rate of principal payments, including prepayments, ofthe related Mortgage Loans and to the level of the Index. The Mortgage Loans generallycan be prepaid at any time without penalty. In addition, the rate of principal payments(including prepayments) of the Mortgage Loans is likely to vary, and may vary considera-bly, from pool to pool. As illustrated in the tables below, it is possible that investors in theJS, HS, CS and SA Classes would lose money on their initial investments under certainIndex and prepayment scenarios.

Changes in the Index may not correspond to changes in prevailing mortgage interest rates. It ispossible that lower prevailing mortgage interest rates, which might be expected to result in fasterprepayments, could occur while the level of the Index increased.

The information shown in the yield tables has been prepared on the basis of the PricingAssumptions and the assumptions that

Weighted Average Lives of the CertiÑcates

The weighted average life of a CertiÑcate is determined by

(a) multiplying the amount of the reduction, if any, of the principal balance of the CertiÑcatefrom one Distribution Date to the next Distribution Date by the number of years from theSettlement Date to the second such Distribution Date,

(b) summing the results, and

(c) dividing the sum by the aggregate amount of the reductions in principal balance of theCertiÑcate referred to in clause (a).

For a description of the factors which may inÖuence the weighted average life of a CertiÑcate, see""Description of CertiÑcatesÌWeighted Average Life and Final Distribution Date'' in the REMICProspectus.

In general, the weighted average lives of the CertiÑcates will be shortened if the level ofprepayments of principal of the related Mortgage Loans increases. However, the weighted averagelives will depend upon a variety of other factors, including

‚ the timing of changes in the rate of principal payments,

‚ the priority sequences of payments of principal of the Classes, and

‚ in the case of the Group 3 and Group 5 Classes, the payment of principal of certain Classes inaccordance with the Principal Balance Schedules.

See ""ÌDistributions of Principal'' above.

The eÅect of these factors may diÅer as to various Classes and the eÅects on any Class may varyat diÅerent times during the life of that Class. Accordingly, we can give no assurance as to the

S-35

weighted average life of any Class. Further, to the extent the prices of the CertiÑcates representdiscounts or premiums to their original principal balances, variability in the weighted average lives ofthose Classes of CertiÑcates could result in variability in the related yields to maturity. For an exampleof how the weighted average lives of the Classes may be aÅected at various constant prepayment rates,see the Decrement Tables below.

Decrement Tables

The following tables indicate the percentages of original principal balances of the speciÑed Classesthat would be outstanding after each date shown at various constant PSA rates, and the correspondingweighted average lives of those Classes. The tables have been prepared on the basis of the PricingAssumptions. However, in the case of the information set forth for each Class under 0% PSA, weassumed that the underlying Mortgage Loans have the original and remaining terms to maturity andbear interest at the annual rates speciÑed in the table below.

Original RemainingMortgage Loans Relating to Terms Terms to InterestTrust Assets SpeciÑed Below to Maturity Maturity Rates

Group 1 Underlying REMIC CertiÑcates 360 months 348 months 9.50%Group 2 MBS 360 months 360 months 8.00%Group 3 MBS 360 months 360 months 8.25%Group 4 MBS 180 months 180 months 7.00%Group 5 MBS 360 months 360 months 8.00%Group 6 MBS 240 months 240 months 8.00%Group 7 MBS 180 months 180 months 7.50%Group 8 MBS 180 months 180 months 7.50%

It is unlikely

‚ that all of the underlying Mortgage Loans will have the interest rates, WALAs or remainingterms to maturity assumed or

‚ that the underlying Mortgage Loans will prepay at any constant PSA level.

In addition, the diverse remaining terms to maturity of the Mortgage Loans could produce sloweror faster principal distributions than indicated in the tables at the speciÑed constant PSA rates. Thisis the case even if the dispersion of weighted average remaining terms to maturity and the weightedaverage WALAs of the Mortgage Loans are identical to the dispersion speciÑed in the PricingAssumptions.

Characteristics of the R and RL Classes

The R and RL Classes will not have principal balances and will not bear interest. If any assets ofthe Trust remain after the principal balances of all Classes are reduced to zero, we will pay the Holderof the R Class the proceeds from those assets. If any assets of the Lower Tier REMIC remain after theprincipal balances of the Lower Tier Regular Interests are reduced to zero, we will pay the proceeds ofthose assets to the Holder of the RL Class. Fannie Mae does not expect that any material assets willremain in either case.

A Residual CertiÑcate will be subject to certain transfer restrictions. We will not permit transferof record or beneÑcial ownership of a Residual CertiÑcate to a ""disqualiÑed organization.'' In addition,we will not permit transfer of record or beneÑcial ownership of a Residual CertiÑcate to any personthat is not a ""U.S. Person'' or a foreign person subject to United States income taxation on a net basison income derived from that CertiÑcate. Any transferee of a Residual CertiÑcate must execute anddeliver an aÇdavit and an Internal Revenue Service Form W-9 (or, if applicable, a Form W-8ECI) onwhich the transferee provides its taxpayer identiÑcation number. See ""Description of CertiÑcatesÌSpecial Characteristics of Residual CertiÑcates'' and ""Certain Federal Income Tax ConsequencesÌTaxation of BeneÑcial Owners of Residual CertiÑcates'' in the REMIC Prospectus. The aÇdavit mustalso state that the transferee is a ""U.S. Person'' or a foreign person subject to United States incometaxation on a net basis on income derived from that CertiÑcate and that, if the transferee is apartnership for U.S. federal income tax purposes, each person or entity that holds an interest(directly, or indirectly through a pass-through entity) in the partnership is a ""U.S. Person'' or aforeign person subject to United States income taxation on a net basis on income derived from thatCertiÑcate. In addition, the transferee must receive an aÇdavit containing these same representationsfrom any new transferee. Transferors of a Residual CertiÑcate should consult with their own taxadvisors for further information regarding such transfers.

Treasury Department regulations (the ""Regulations'') provide that a transfer of a ""noneconomicresidual interest'' will be disregarded for all federal tax purposes unless no signiÑcant purpose of thetransfer is to impede the assessment or collection of tax. The R and RL Classes will constitutenoneconomic residual interests under the Regulations. Having a signiÑcant purpose to impede theassessment or collection of tax means that the transferor of a Residual CertiÑcate knew or should haveknown that the transferee would be unwilling or unable to pay taxes due on its share of the taxableincome of the REMIC trust (that is, the transferor had ""improper knowledge'').

As discussed under the caption ""Special Characteristics of Residual CertiÑcates'' in the REMICProspectus, the Regulations presume that a transferor does not have improper knowledge if twoconditions are met. The Treasury Department has amended the Regulations to provide additionalrequirements that a transferor must satisfy to avail itself of the safe harbor regarding the presumedlack of improper knowledge. For transfers occurring on or after August 19, 2002, a transferor of aResidual CertiÑcate is presumed not to have improper knowledge if, in addition to meeting the twoconditions discussed in the REMIC Prospectus, both (i) the transferee represents that it will notcause income from the Residual CertiÑcate to be attributed to a foreign permanent establishment orÑxed base of the transferee or another taxpayer and (ii) the transfer satisÑes either the ""asset test'' orthe ""formula test.'' The representation described in (i) will be included in the aÇdavit discussedabove. See ""Description of CertiÑcatesÌSpecial Characteristics of Residual CertiÑcates'' and ""Cer-tain Federal Income Tax ConsequencesÌTaxation of BeneÑcial Owners of Residual CertiÑcates'' inthe REMIC Prospectus.

A transfer satisÑes the asset test if (i) the transferee's gross assets exceed $100 million and its netassets exceed $10 million (in each case, at the time of the transfer and at the close of each of thetransferee's two Ñscal years preceding the year of transfer), (ii) the transferee is an ""eligiblecorporation'' and the transferee agrees in writing that any subsequent transfer of the ResidualCertiÑcate will be to an eligible corporation and will comply with the safe harbor and satisfy the assettest, and (iii) the facts and circumstances known to the transferor do not reasonably indicate that thetaxes associated with the Residual CertiÑcate will not be paid. A transfer satisÑes the formula test if

S-50

the present value of the anticipated tax liabilities associated with holding the Residual CertiÑcate isless than or equal to the present value of the sum of (i) any consideration given to the transferee toacquire the Residual CertiÑcate, (ii) expected future distributions on the Residual CertiÑcate, and(iii) anticipated tax savings associated with holding the Residual CertiÑcate as the related REMICtrust generates losses. The Regulations contain additional details regarding their application and youshould consult your own tax advisor regarding the application of the Regulations to a transfer of aResidual CertiÑcate.

The Holder of the R Class will be considered to be the holder of the ""residual interest'' in theREMIC constituted by the Trust, and the Holder of the RL Class will be considered to be the holder ofthe ""residual interest'' in the REMIC constituted by the Lower Tier REMIC. See ""Certain FederalIncome Tax Consequences'' in the REMIC Prospectus. Pursuant to the Trust Agreement, we will beobligated to provide to these Holders (i) information necessary to enable them to prepare their federalincome tax returns and (ii) any reports regarding the R or RL Class that may be required under theCode.

CERTAIN ADDITIONAL FEDERAL INCOME TAX CONSEQUENCES

The CertiÑcates and payments on the CertiÑcates are not generally exempt from taxation.Therefore, you should consider the tax consequences of holding a CertiÑcate before you acquire one.The following tax discussion supplements the discussion under the caption ""Certain Federal IncomeTax Consequences'' in the REMIC Prospectus. When read together, the two discussions describe thecurrent federal income tax treatment of beneÑcial owners of CertiÑcates. These two tax discussions donot purport to deal with all federal tax consequences applicable to all categories of beneÑcial owners,some of which may be subject to special rules. In addition, these discussions may not apply to yourparticular circumstances for one of the reasons explained in the REMIC Prospectus. You shouldconsult your own tax advisors regarding the federal income tax consequences of holding and disposingof CertiÑcates as well as any tax consequences arising under the laws of any state, local or foreigntaxing jurisdiction.

REMIC Elections and Special Tax Attributes

We will elect to treat the Lower Tier REMIC and the Trust as REMICs for federal income taxpurposes. The REMIC CertiÑcates, other than the R and RL Classes, will be designated as the""regular interests,'' and the R Class will be designated as the ""residual interest,'' in the REMICconstituted by the Trust. The Lower Tier Regular Interests will be designated as the ""regularinterests'' and the RL Class will be designated as the ""residual interest'' in the Lower Tier REMIC.

Because the Lower Tier REMIC and the Trust will qualify as REMICs, the REMIC CertiÑcatesand any related RCR CertiÑcates generally will be treated as ""regular or residual interests in aREMIC'' for domestic building and loan associations, as ""real estate assets'' for real estate investmenttrusts, and, except for the R and RL Classes, as ""qualiÑed mortgages'' for other REMICs. See""Certain Federal Income Tax ConsequencesÌREMIC Election and Special Tax Attributes'' in theREMIC Prospectus.

Taxation of BeneÑcial Owners of Regular CertiÑcates

The Notional Classes and the Accrual Classes will be issued with original issue discount (""OID''),and certain other Classes of REMIC CertiÑcates may be issued with OID. If a Class is issued withOID, a beneÑcial owner of a CertiÑcate of that Class generally must recognize some taxable income inadvance of the receipt of the cash attributable to that income. See ""Certain Federal Income TaxConsequencesÌTaxation of BeneÑcial Owners of Regular CertiÑcatesÌTreatment of Original IssueDiscount'' in the REMIC Prospectus. In addition, certain Classes of REMIC CertiÑcates may betreated as having been issued at a premium. See ""Certain Federal Income Tax Conse-quencesÌTaxation of BeneÑcial Owners of Regular CertiÑcatesÌRegular CertiÑcates Purchased at aPremium'' in the REMIC Prospectus.

S-51

The Prepayment Assumptions that will be used in determining the rate of accrual of OID will beas follows:

Group Prepayment Assumption

1 650% PSA2 382% PSA3 218% PSA4 200% PSA5 215% PSA6 523% PSA7 325% PSA8 333% PSA

See ""Certain Federal Income Tax ConsequencesÌTaxation of BeneÑcial Owners of Regular CertiÑ-catesÌTreatment of Original Issue DiscountÌDaily Portions of Original Issue Discount'' in theREMIC Prospectus. No representation is made as to whether the Mortgage Loans underlying theMBS will prepay at any of those rates or any other rate. See ""Description of the CertiÑcatesÌWeighted Average Lives of the CertiÑcates'' in this prospectus supplement and ""Description ofCertiÑcatesÌWeighted Average Life and Final Distribution Date'' in the REMIC Prospectus.

Taxation of BeneÑcial Owners of Residual CertiÑcates

For purposes of determining the portion of the taxable income of the Trust (or the Lower TierREMIC) that generally will not be treated as excess inclusions, the rate to be used is 120% of the""federal long-term rate.'' The rate will be published on or about February 20, 2003. See ""CertainFederal Income Tax ConsequencesÌTaxation of BeneÑcial Owners of Residual CertiÑcatesÌTreat-ment of Excess Inclusions'' and ""ÌForeign InvestorsÌResidual CertiÑcates'' in the REMICProspectus.

Taxation of BeneÑcial Owners of RCR CertiÑcates

General. The RCR Classes will be created, sold and administered pursuant to an arrangementthat will be classiÑed as a grantor trust under subpart E, part I of subchapter J of the Code. TheREMIC CertiÑcates that are exchanged for RCR CertiÑcates (including any exchanges eÅective onthe Settlement Date) will be the assets of the trust, and the RCR CertiÑcates will represent anownership interest in those REMIC CertiÑcates. For a general discussion of the federal income taxtreatment of beneÑcial owners of REMIC CertiÑcates, see ""Certain Federal Income Tax Conse-quences'' in the REMIC Prospectus.

The RCR Classes (each, a ""Combination RCR Class'') will represent the beneÑcial ownership ofthe underlying REMIC CertiÑcates set forth in Schedule 1. Each CertiÑcate of a CombinationRCR Class (a ""Combination RCR CertiÑcate'') will represent beneÑcial ownership of undividedinterests in two or more underlying REMIC CertiÑcates.

Combination RCR Classes. A beneÑcial owner of a Combination RCR CertiÑcate will be treatedas the beneÑcial owner of a proportionate interest in the REMIC CertiÑcates underlying thatCombination RCR CertiÑcate. Except in the case of a beneÑcial owner that acquires a CombinationRCR CertiÑcate in an exchange described under ""ÌExchanges'' below, a beneÑcial owner of aCombination RCR CertiÑcate must allocate its cost to acquire that CertiÑcate among the underlyingREMIC CertiÑcates in proportion to their relative fair market values at the time of acquisition. Suchan owner should account for its ownership interest in each underlying REMIC CertiÑcate as describedunder ""ÌTaxation of BeneÑcial Owners of Regular CertiÑcates'' above and ""Certain Federal IncomeTax ConsequencesÌTaxation of BeneÑcial Owners of Regular CertiÑcates'' in the REMIC Prospectus.When a beneÑcial owner sells a Combination RCR CertiÑcate, the owner must allocate the saleproceeds among the underlying REMIC CertiÑcates in proportion to their relative fair market valuesat the time of sale.

S-52

Exchanges. If a beneÑcial owner exchanges one or more REMIC CertiÑcates for the related RCRCertiÑcate or CertiÑcates in the manner described under ""Description of the CertiÑcatesÌCombina-tion and Recombination'' in this prospectus supplement, the exchange will not be taxable. Likewise, ifa beneÑcial owner exchanges one or more RCR CertiÑcates for the related REMIC CertiÑcate orCertiÑcates in the manner described in that discussion, the exchange will not be a taxable exchange. Ineach of these cases, the beneÑcial owner will be treated as continuing to own after the exchange thesame combination of interests in the related REMIC CertiÑcates (or the same interest in the relatedREMIC CertiÑcate) that it owned immediately prior to the exchange.

Tax Return Disclosure Requirements

The Treasury Department recently issued Regulations directed at ""tax shelters'' that could beread to apply to transactions generally not considered to be tax shelters. These Regulations requirethat taxpayers that participate in a ""reportable transaction'' disclose such transaction on their taxreturns by attaching IRS Form 8886, and retain information related to the transaction. A transactionmay be a ""reportable transaction'' based upon any of several indicia, one or more of which may bepresent with respect to the CertiÑcates. You should consult your tax advisor concerning any possibledisclosure obligation with respect to your investment in the CertiÑcates.

PLAN OF DISTRIBUTION

General. We are obligated to deliver the CertiÑcates to Credit Suisse First Boston LLC (the""Dealer'') in exchange for the Group 1 Underlying REMIC CertiÑcates and the Trust MBS. TheDealer proposes to oÅer the CertiÑcates directly to the public from time to time in negotiatedtransactions at varying prices to be determined at the time of sale. The Dealer may eÅect thesetransactions to or through other dealers.

Increase in CertiÑcates. Before the Settlement Date, we and the Dealer may agree to oÅerGroup 2, 3, 4, 5, 6, 7 or 8 Classes in addition to those contemplated as of the date of this prospectussupplement. In this event, we will increase the related Trust MBS in principal balance, but we expectthat all these additional Trust MBS will have the same characteristics as described under ""Descriptionof the CertiÑcatesÌThe Trust MBS'' in this prospectus supplement. The proportion that the originalprincipal balance of each Group 2, 3, 4, 5, 6, 7 or 8 Class bears to the aggregate original principalbalance of all Group 2, 3, 4, 5, 6, 7 or 8 Classes, respectively, will remain the same. In addition, thedollar amounts shown in the Principal Balance Schedules will be increased to correspond to theincrease of the principal balances of the applicable Classes.

LEGAL MATTERS

Sidley Austin Brown & Wood LLP will provide legal representation for Fannie Mae. McKeeNelson LLP will provide legal representation for the Dealer.
