CERTAIN RISK CONSIDERATIONSTHE SECURITIES ARE NOT SUITABLE INVESTMENTS FOR ALL INVESTORS. IN PARTICULAR, NO

INVESTOR SHOULD PURCHASE SECURITIES OF ANY CLASS UNLESS THE INVESTOR UNDERSTANDS ANDIS ABLE TO BEAR THE PREPAYMENT, REDEMPTION, YIELD, LIQUIDITY AND MARKET RISKS ASSOCIATEDWITH THAT CLASS.

The Securities are complex securities and it is important that each investor in any Class possess, either alone or together with aninvestment advisor, the expertise necessary to evaluate the information contained and incorporated in this Supplement in the context ofthat investor's Ñnancial situation.

The yield of each Class will depend upon its purchase price, the rate of payments on the related Asset or Assets (which will besensitive to the rate of principal payments on the related Mortgages), the actual characteristics of the related Mortgages and, in the caseof the Callable Classes, whether a redemption of the Group 1 or Group 7 Asset occurs (as described under ""General Information ÌStructure of Transaction Ì The Callable Assets'' in this Supplement). The yields of the Floating Rate and Inverse Floating Rate Classeswill also be sensitive to the level of LIBOR or the Ten-Year Treasury Index (each, an ""Index''). The Mortgages are subject toprepayment at any time without penalty. Mortgage prepayment rates are likely to Öuctuate signiÑcantly from time to time, as is the levelof each Index. In addition, principal payments on the Mortgages underlying the Group 2 through Group 5, Group 8 and Group 11 throughGroup 14 Assets will be allocated among the various classes of the related Series, and such allocations will aÅect the sensitivity of eachrelated Class of this Series to Mortgage prepayment rates generally. Investors should consider the associated risks, including:

‚ Fast prepayment rates on the related Mortgages or, in the case of the Callable Classes, a redemption of the related CallableAsset, can reduce the yields of the Interest Only Classes and any other Classes purchased at a premium over their principalamounts. Under some prepayment and redemption scenarios, investors in such Classes (especially Interest Only and CallableClasses) could fail to fully recover their investments.

‚ Slow prepayment rates on the related Mortgages and, in the case of the Callable Classes, the absence of a redemption of therelated Callable Asset, can reduce the yields of the Principal Only Classes and any other Classes purchased at a discount totheir principal amounts.

‚ Small diÅerences in the characteristics of the Mortgages can have a signiÑcant eÅect on the weighted average lives and yieldsof the related Classes.

‚ Low levels of LIBOR can reduce the yields of the Floating Rate Classes. Conversely, high levels of the applicable Index cansigniÑcantly reduce the yields of the Inverse Floating Rate Classes and (especially in combination with fast Mortgageprepayment rates) may result in the failure of investors in the Inverse Floating Rate Classes that are also Interest OnlyClasses to fully recover their investments.

‚ Because Retail Class investors will receive principal payments subject to the priorities, limitations and allocations described inthis Supplement, the weighted average lives of Retail Class Units will vary among diÅerent investors. In addition, the RetailClasses are Callable Classes. As a result, the weighted average lives and yields to maturity of the Retail Class Units aresubject to substantial volatility.

‚ The Group 1 and Group 7 Assets each consists of a separate Callable Class of Freddie Mac's CPCs, Series C057(""Series C057''). As further described under ""General Information Ì Structure of Transaction Ì The Callable Assets'' inthis Supplement, each such Asset may be redeemed on any Payment Date beginning in September 1998 at the direction ofthe holder of the related Call Class of Series C057. The holder of the related Call Class, which may include the Underwriter(or an aÇliate), may also be a Holder of one or more Callable Classes of this Series, such as an Interest Only Class, whichmay aÅect such holder's decision whether to direct a redemption of the Group 1 or Group 7 Asset. The redemption of theGroup 1 or Group 7 Asset would result in the concurrent retirement of all related Callable Classes then outstanding andwould reduce the weighted average lives of such Classes, perhaps signiÑcantly.

‚ In general, principal payment rates on the Support, Pass-Through and Sequential Pay Classes are likely to exhibit a highersensitivity to prepayments on the related Mortgages than are principal payment rates on the PAC Classes.

‚ The Group 3, Group 4 and Group 13 Assets were structured as TAC Classes, the Group 2 and Group 12 Assets werestructured as Scheduled Classes, the Group 5 Assets were structured as PAC Classes, the Group 11 Asset was structured as aType I PAC Class and the Group 8 Assets were structured as Type III PAC Classes. However, certain of such TAC,Scheduled and PAC Classes have not received principal payments in accordance with their schedules and there can be noassurance that any of such Classes will do so in the future.

‚ The Group 14 Asset is a Notional Class whose notional principal amount reduces proportionately with the Strip Class withinSeries G021. Therefore, the rate of reduction in the notional principal balance of the Group 14 Asset is approximately thesame as the rate of reduction of its underlying GNMA-Related Securities.

See ""Prepayment and Yield Analysis'' in this Supplement.

The Underwriter intends to make a market for the purchase and sale of the Securities after their initial issuance but has noobligation to do so. There is no assurance that such a secondary market will develop or, if it develops, that it will continue.Consequently, investors may not be able to sell their Securities readily or at prices that will enable them to realize their desired yield.The market values of the Securities are likely to Öuctuate; such Öuctuations may be signiÑcant and could result in signiÑcant losses toinvestors. In addition, the redemption feature of the Group 1 and Group 7 Assets may aÅect the market values of the Callable Classes.

The secondary markets for mortgage-related securities have experienced periods of illiquidity and can be expected to do so in thefuture. Illiquidity can have a severely adverse eÅect on the prices of Securities that are especially sensitive to prepayment, redemption orinterest rate risk or that have been structured to meet the investment requirements of limited categories of investors.

GENERAL INFORMATION

Multiclass Agreement

Freddie Mac will create the Securities under the Multiclass Mortgage Participation CertiÑcate Agree-ment and the Multiclass Mortgage Security Agreement, each dated as of January 1, 1997, and a TermsSupplement, to be dated the Closing Date (collectively, the ""Multiclass Agreement''). Investors can ordercopies of the Multiclass Agreement by writing or calling the Investor Inquiry Department at Freddie Mac atthe address or phone numbers shown under ""Available Information'' in this Supplement. The MulticlassAgreement is incorporated by reference in this Supplement.

Holders and anyone having a beneÑcial interest in the Securities should refer to the MulticlassAgreement for a complete description of their rights and obligations and the rights and obligations of FreddieMac. Holders and beneÑcial owners of Securities will acquire their Securities subject to all terms andconditions of the Multiclass Agreement, including the Terms Supplement.

S-17

Form of Securities

Non-Retail Classes

The Regular Classes (other than the Retail Classes) and the MACR Classes will be issued and may beheld of record and transferred only on the book-entry system of the Federal Reserve Banks by entities eligibleto maintain book-entry accounts with a Federal Reserve Bank (""Fed Participants''). The Residual Classeswill be issued and may be held of record only in certiÑcated form and will be transferable at Texas CommerceBank National Association or its successor (the ""Registrar''). The Classes other than the Retail Classes willbe issued in the denominations speciÑed under ""Description of Multiclass PCs Ì Form of Multiclass PCs,Holders, Minimum Principal Amounts and Transfers'' in the Multiclass PC OÅering Circular or ""Descriptionof Multiclass Securities Ì Form of Multiclass Securities, Holders, Minimum Principal Amounts andTransfers'' in the Multiclass Securities OÅering Circular.

Retail Classes (QQ and UU Classes)

Each Retail Class will be represented by one or more certiÑcates held by or on behalf of The DepositoryTrust Company or its successor (the ""Retail Depository''). The Retail Depository is a New York-charteredlimited purpose trust company that performs services for its participants (the ""Retail Depository Partici-pants''), principally brokerage Ñrms and other Ñnancial institutions. The Retail Depository will maintain eachRetail Class through its book-entry facilities in principal amounts of $1,000 each (""Retail Class Units''). TheRetail Depository will record the positions held by each Retail Depository Participant in Retail Class Units,whether held for the Retail Depository Participant's own account or for another person.

Investors in a Retail Class will be subject to the rules and procedures of the Retail Depository and RetailDepository Participants in eÅect from time to time. Retail Class investors will not receive certiÑcates. Rather,each investor's ownership interest in a Retail Class will be recorded, in Retail Class Units, on the records ofthe brokerage Ñrm, bank, thrift institution or other Ñnancial intermediary where the investor maintains anaccount for this purpose. In turn, the Ñnancial intermediary's interest in a Retail Class will be recorded, inRetail Class Units, on the records of the Retail Depository (or of a Retail Depository Participant that acts asagent for the Ñnancial intermediary, if the intermediary is not itself a Retail Depository Participant). Investorsmay transfer their Retail Class Units only through their brokers or other Ñnancial intermediaries, incompliance with their procedures.

Holders

The term ""Holders'' means (i) in the case of a Regular Class (other than a Retail Class) or a MACRClass, the Fed Participants that appear on the book-entry records of a Federal Reserve Bank as holders of thatClass, (ii) in the case of a Retail Class, the Retail Depository or its nominee and (iii) in the case of a ResidualClass, the entities or individuals that appear on the records of the Registrar as the registered holders of thatClass. The beneÑcial owner of a Security is not necessarily the Holder.

Structure of Transaction

General

This Series will be a ""Double-Tier Series.'' The Regular Classes of Multiclass PCs and MulticlassSecurities and the R Class will represent beneÑcial ownership interests in the Upper-Tier REMIC Pool. TheUpper-Tier REMIC Pool will consist of (i) the classes of ""regular interests'' in three Lower-Tier REMICPools (the ""Mortgage Securities'') and (ii) a non-interest bearing cash deposit of $1,999.98 (the ""RetailRounding Account''), to be applied as described in this Supplement. The RA, RB and RC Classes will eachrepresent the residual interest in a separate Lower-Tier REMIC Pool.

The Ñrst Lower-Tier REMIC Pool will contain the Group 1 Asset. The second Lower-Tier REMIC Poolwill contain the Group 7 Asset. The third Lower-Tier REMIC Pool will contain the other Assets.

The Lower-Tier REMIC Pool containing the Group 1 Asset will also include a non-interest bearing cashdeposit of $57,000 (the ""Group 1 Cash Deposit'') to be applied to the payment of interest on the GA and HAClasses (and their corresponding Mortgage Security) through the twelfth Payment Date. The Lower-Tier

S-18

REMIC Pool containing the Group 7 Asset will also include a non-interest bearing cash deposit of $37,500(the ""Group 7 Cash Deposit'') to be applied to the payment of interest on the QA, QD and TA Classes (andtheir corresponding Mortgage Security) through the twelfth Payment Date. See ""Payments Ì Interest ÌAscending Rate and Descending Rate Classes'' in this Supplement. The Lower-Tier REMIC Pool containingthe Group 14 Asset will also include a non-interest bearing cash deposit of $10,000 (the ""Group 14 CashDeposit''). See Payments Ì Interest Ì Excess Class'' in this Supplement.

The Underwriter intends to acquire the Group 1 and Group 7 Assets upon their issuance, and the otherAssets in privately negotiated transactions, before delivering them to Freddie Mac on the Closing Date. Onthe Closing Date, Freddie Mac expects to acquire the Assets from the Underwriter in exchange for theMulticlass PCs and the Multiclass Securities.

The Callable Assets

Each Callable Asset will represent an interest in a separate ""Pass-Through Pool'' consisting of a singleGiant PC and the rights of such Pass-Through Pool under a Guaranteed Investment and Fee Contract, asdescribed in the Callable Asset OÅering Circular. Each Giant PC will represent a pass-through interest in thecash Öows provided by its underlying PCs.

The Callable Assets are described generally under ""Terms Sheet Ì The Assets'' in this Supplement. Foradditional information about the Callable Assets, see the Callable Asset OÅering Circular and ""Prepaymentand Yield Analysis Ì Prepayment and Weighted Average Life Considerations Ì The Callable Assets'' in thisSupplement. The cover page and terms sheet from the Callable Asset OÅering Circular are reproduced asExhibit I to this Supplement.

Each Callable Asset may be redeemed by Freddie Mac at the direction of the holder of the related CallClass of Series C057 on any Payment Date beginning in September 1998 if, as of the date Freddie Macreceives notice of intention to redeem, the market value of the Giant PC underlying such Callable Assetexceeds its principal amount. A redemption is most likely to occur if prevailing interest rates have declined.See ""Prepayment and Yield Analysis Ì Yield Considerations'' in this Supplement.

The holder of the related Call Class may exercise its option to cause a redemption of a Callable Assetupon payment to Freddie Mac of a fee equal to 1/32 of 1% of the outstanding principal amount of the CallableAsset (but not less than $7,500). The redemption price of a Callable Asset will equal the sum of:

(a) its outstanding principal amount;

(b) 30 days' interest on such principal amount at the Class Coupon of such Callable Asset; and

(c) additional interest at such Class Coupon for the period from the Ñrst day of the month ofredemption to the redemption date, calculated on the principal amount to which such Callable Assetwould have been reduced on that redemption date if no redemption were to occur (that is, approximately14 days' interest on such reduced principal amount).

Payment of the redemption price will be in lieu of any payment of principal and interest that would otherwisebe made on that Payment Date. Upon a redemption, the holder of the related Call Class will receive the GiantPC underlying a Callable Asset. See ""Payments Ì Redemption and Exchange'' in the Callable Asset OÅeringCircular.

Upon a redemption of a Callable Asset, each Holder of a related Security of this Series will receive theoutstanding principal amount, if applicable, of that Security plus 30 days' interest at its applicable ClassCoupon on its principal or notional principal amount. In addition, each Holder of a related Fixed Rate,Ascending Rate, Descending Rate or Delay Class will receive additional interest at its applicable ClassCoupon (as adjusted, in the case of an Ascending Rate, Descending Rate or Delay Class) for the period fromthe Ñrst day of the month of redemption to the redemption date, based on a principal or notional principalamount equal to the principal amount of the Holder's Security that would have remained outstandingimmediately after such redemption date if no redemption were to occur (that is, approximately 14 days'interest on such, possibly reduced, principal or notional principal amount). Such additional accrued interestwill not be payable on the FN Class. The additional accrued interest payable on a Retail Class will be

S-19

allocated among all Retail Class Units of such Retail Class equally. The SN Class will receive any additionalinterest payable on the Group 7 Asset in excess of that which is passed through to Holders of other relatedCallable Classes.

If the holder of a Call Class notiÑes Freddie Mac that it intends to exercise its option to redeem therelated Callable Asset, Freddie Mac, prior to the last day of the calendar month preceding the month in whichsuch redemption is to occur, will notify the Holders of any related outstanding Callable Classes of this Seriesthat such Classes will be retired on the next Payment Date. On the Ñrst business day of the month ofredemption, Freddie Mac will reduce the Class Factor for such outstanding Callable Classes to zero.

The Group 2 through Group 5, Group 8 and Group 11 through Group 14 Assets (Multiclass Assets)

The Group 2 through Group 5, Group 8 and Group 11 through Group 14 Assets (collectively, the""Multiclass Assets'') consist of Classes of Freddie Mac Multiclass Securities or Multiclass PCs and aredescribed generally under ""Terms Sheet Ì The Assets'' in this Supplement. For additional information aboutsuch Assets, see the applicable Asset OÅering Circulars and ""Prepayment and Yield Analysis Ì Prepaymentand Weighted Average Life Considerations Ì The ""Multiclass Assets'' in this Supplement. The cover pagesand terms sheets from such Asset OÅering Circulars are reproduced as Exhibits II through V to thisSupplement.

It should be noted that there have been material changes in facts and circumstances since the dates ofsuch Asset OÅering Circulars, including changes in prepayment rates, prevailing interest rates and othereconomic factors, which may limit the usefulness of, and be directly contrary to the assumptions used inpreparing the information set forth in, such documents.

The Group 6, Group 9, Group 10 and Group 15 Assets (PC Assets)

The Group 6, Group 9, Group 10 and Group 15 Assets (collectively, the ""PC Assets'') are PCs, whichmay include Gold Mortgage Participation CertiÑcates (""Gold PCs'') and/or Gold Giant Mortgage Participa-tion CertiÑcates (""Gold Giant PCs''). Gold PCs represent undivided interests in discrete pools consisting ofspeciÑed Mortgages. Gold Giant PCs represent beneÑcial ownership interests in discrete pools consisting ofspeciÑed Gold PCs (or, in some cases, other Gold Giant PCs).

The Mortgages

The Mortgages underlying the Assets are Ñxed-rate, Ñrst lien, residential mortgages and mortgageparticipations. For purposes of this Supplement, Freddie Mac has made certain assumptions regarding theremaining terms to maturity, loan ages and interest rates of the Mortgages underlying the PC and CallableAssets. See ""Terms Sheet Ì Mortgage Characteristics'' in this Supplement. The weighted average remainingterms to maturity, weighted average loan ages and weighted average interest rates of the Mortgages underlyingthe Multiclass Assets, as of September 1, 1997, are shown under ""Terms Sheet Ì Mortgage Characteristics''in this Supplement. However, the characteristics of most of the Mortgages diÅer from those assumed orshown, in some cases signiÑcantly. This is the case even if the weighted average characteristics of theMortgages are the same as those of mortgages having the characteristics assumed or shown. Small diÅerencesin the characteristics of the Mortgages underlying each Asset Group can have a signiÑcant eÅect on thepayment behavior of the related Assets and the weighted average lives and yields of the related Classes. See""Prepayment and Yield Analysis'' in this Supplement.

PAYMENTS

Payment Dates; Record Dates

Freddie Mac will make payments of principal and interest on the Securities to Holders entitled to suchpayments on each Payment Date, beginning in the month following the Closing Date. A ""Payment Date''means (i) in the case of the Regular Classes of Multiclass PCs, the related MACR Classes and the RA andRB Classes, the 15th of each month or, if the 15th is not a ""Business Day'' (as deÑned under ""OÅering

S-20

Circular Summary Ì Payment Dates'' in the Multiclass PC OÅering Circular), the next Business Day or(ii) in the case of the Regular Classes of Multiclass Securities, the related MACR Class and the R and RCClasses, the 25th day of each month or, if the 25th is not a ""Business Day'' (as deÑned under ""OÅeringCircular Summary Ì Payment Dates'' in the Multiclass Securities OÅering Circular), the Ñrst Business Dayfollowing the 25th.

On each Payment Date, any payment on a Security will be made to the Holder of record as of the end ofthe preceding calendar month (each, a ""Record Date''). On each Payment Date, the Retail Depository willremit payments on each Retail Class to those Retail Depository Participants that held Retail Class Units ofrecord as of the related Record Date.

Method of Payment

Non-Retail Classes

A Federal Reserve Bank will credit payments on the Regular Classes (other than the Retail Classes) andthe MACR Classes to the accounts of Holders of these Classes monthly on each Payment Date.

The Registrar will mail any payments on the Residual Classes by check to the addresses of the Holders ofthese Classes as they appear on the Registrar's records, not later than the applicable Payment Date. A Holderof a Residual Class will be required to present the Holder's certiÑcate to the Registrar for payment under thecircumstances described under ""Description of Multiclass PCs Ì Form of Multiclass PCs, Holders, Mini-mum Principal Amounts and Transfers'' in the Multiclass PC OÅering Circular and ""Description ofMulticlass Securities Ì Form of Multiclass Securities, Holders, Minimum Principal Amounts and Transfers''in the Multiclass Securities OÅering Circular.

A Holder that is not also the beneÑcial owner of a Security, and each other Ñnancial intermediary in thechain to the beneÑcial owner, will be responsible for remitting payments to their customers.

Retail Classes

The Registrar will act as Freddie Mac's paying agent for the Retail Classes. The Registrar will makepayments on the Retail Classes to the Retail Depository in immediately available funds. The RetailDepository will be responsible for crediting payments to the accounts of the appropriate Retail DepositoryParticipants in accordance with the Retail Depository's normal procedures. Each Retail Depository Partici-pant, and each other Ñnancial intermediary in the chain to the beneÑcial owner, will be responsible forremitting payments to their customers. Thus, investors in a Retail Class may experience some delay in thereceipt of payments.

Interest

Freddie Mac will pay interest on each Payment Date to the Holders of each Class of Securities on whichinterest has accrued, except in the case of the Accrual Classes, which will receive payments as described under""Accrual Classes'' below.

Categories of Classes

For purposes of interest payments, the Classes of Multiclass PCs and Multiclass Securities will becategorized as shown under ""Interest Type'' on the cover page of this Supplement, and the MACR Classeswill be categorized as shown under ""Interest Type'' on Appendix 1 to this Supplement. The abbreviations usedon the cover page and Appendix 1 are explained under ""Description of Multiclass PCs Ì Standard DeÑnitionsand Abbreviations for Classes'' in the Multiclass PC OÅering Circular and ""Description of MulticlassSecurities Ì Standard DeÑnitions and Abbreviations for Classes'' in the Multiclass Securities OÅeringCircular.

S-21

Accrual Periods

The Accrual Period for the Fixed Rate, Delay, Ascending Rate and Descending Rate Classes will be thecalendar month preceding the related Payment Date. The Accrual Period for the Floating Rate and InverseFloating Rate Classes other than the Delay Classes (the ""Non-Delay Classes'') will be from the 15th of themonth preceding the related Payment Date to the 15th of the month of that Payment Date in the case of theMulticlass PCs and from the 25th of the month preceding the related Payment Date to the 25th of the monthof that Payment Date in the case of the Multiclass Securities. In each case, interest will be calculated on thebasis of a 360-day year consisting of twelve 30-day months. Interest payable on any Class on any PaymentDate will consist of 30 days' interest on its balance as of the related Record Date. In addition, upon aredemption of a Callable Asset, Holders of certain related Callable Classes will receive additional interest asdescribed under ""General Information Ì Structure of Transaction Ì The Callable Assets'' in thisSupplement.

Fixed Rate Classes

The Fixed Rate Classes will bear interest at the Class Coupons shown on the cover page of thisSupplement.

Ascending Rate and Descending Rate Classes

The Ascending Rate and Descending Rate Classes will bear interest as shown under ""Terms Sheet ÌClass Coupons'' in this Supplement.

The Group 1 Cash Deposit will be applied to the payment of interest on the GA and HA Classes throughthe twelfth Payment Date, and the Group 7 Cash Deposit will be applied to the payment of interest on theQA, QD and TA Classes through the twelfth Payment Date. As of any Payment Date, to the extent that thebalance remaining in the Group 1 or Group 7 Cash Deposit, as applicable, exceeds the amount that may benecessary to pay interest on the GA and HA Classes or the QA, QD and TA Classes, respectively, onsubsequent Payment Dates, such excess will be passed through to the Holders of the RA or RB Class,respectively.

Principal Only Classes

The EA, ED, LA, MO, PO and W Classes will be Principal Only Classes and will not bear interest.

Notional Classes

The Notional Classes will not receive principal payments. For convenience in describing interestpayments, the Notional Classes will have notional principal amounts. The table under ""Terms Sheet ÌNotional Classes'' in this Supplement shows the original notional principal amounts of the Notional Classesand the Class, Classes or Asset (or portion thereof) with which each Notional Class (or portions thereof) willreduce proportionately.

Floating Rate and Inverse Floating Rate Classes

The Floating Rate and Inverse Floating Rate Classes will bear interest as shown under ""Terms Sheet ÌClass Coupons'' in this Supplement. The Class Coupons for the Floating Rate and Inverse Floating RateClasses will be based on (i) the arithmetic mean of the London interbank oÅered quotations for one-monthEurodollar deposits (""LIBOR'') or (ii) the weekly average yield, expressed as a per annum rate, on U.S.Treasury Securities adjusted to a constant maturity of ten years (the ""Ten-Year Treasury Index'').

For information regarding the manner in which Freddie Mac determines the Indices and calculates theClass Coupons for the Floating Rate and Inverse Floating Rate Classes, see ""Description of Multiclass PCs ÌInterest Rate Indices'' in the Multiclass PC OÅering Circular and ""Description of Multiclass Securities ÌInterest Rate Indices'' in the Multiclass Securities OÅering Circular.

S-22

Freddie Mac's determination of either Index and its calculation of the Class Coupons will be Ñnal, exceptin the case of clear error. Investors can get the Index levels and the Class Coupons for the current andpreceding Accrual Periods from Freddie Mac's Internet Web-Site or by writing or calling Freddie Mac'sInvestor Inquiry Department at the address or phone numbers shown under ""Available Information'' in thisSupplement.

Accrual Classes

The K, Z, ZD, ZE, ZF and ZG Classes will be Accrual Classes. No payments of interest will be made onthe K Class on any Payment Date if the Current PSA Rate applicable to that Payment Date is higher than85% PSA or lower than 147.5% PSA. Rather, the interest accrued on the K Class during the related AccrualPeriod will be added to its principal amount on such Payment Date. If the Current PSA Rate applicable to aPayment Date is 85% PSA or lower or is 147.5% PSA or higher, the interest accrued on the K Class during therelated Accrual Period will be paid on the K Class as interest on that Payment Date. No payments of interestwill be made on the other Accrual Classes; rather, interest accrued on any such Accrual Class during eachAccrual Period will be added to its principal amount on the related Payment Date. Payments of principal onthe Accrual Classes (including accrued interest that has been added to their principal amounts) will be madeas described under ""Terms Sheet Ì Allocation of Principal'' in this Supplement.

Excess Class

On any Payment Date on which the notional principal amount of the Group 14 Asset is reduced, theGroup 14 Cash Deposit will be reduced proportionately. The R Class will receive, as interest, the amount ofeach such reduction in such Cash Deposit. For a description of the Group 14 Asset, see the Asset OÅeringCircular for Series G021 and Exhibit IV to this Supplement.

Principal

Freddie Mac will pay principal on each applicable Payment Date to the Holders of the Classes on whichprincipal is then due. The Holders of each such Class will receive principal payments on a pro rata basisamong the Securities of that Class, subject to special allocation procedures for investors in a Retail Class.

Categories of Classes

For purposes of principal payments, the Classes of Multiclass PCs and Multiclass Securities will becategorized as shown under ""Principal or Other Type'' on the cover page of this Supplement, and theMACR Classes will be categorized as shown under ""Principal or Other Type'' on Appendix 1 to thisSupplement. The abbreviations used on the cover page or Appendix 1 are explained under ""Description ofMulticlass PCs Ì Standard DeÑnitions and Abbreviations for Classes'' in the Multiclass PC OÅering Circularand ""Description of Multiclass Securities Ì Standard DeÑnitions and Abbreviations for Classes'' in theMulticlass Securities OÅering Circular.

Component Classes

For convenience in describing principal payments, the FO Class will be a ""Component Class.'' It will bedeemed to consist of two ""Components'' having the designations and original principal amounts shown under""Terms Sheet Ì Components'' in this Supplement. Such Components, together, will constitute a single Classand will not be separately issued or transferable.

For convenience in describing principal payments, the FD, FG, FM, FP, J, K, SD, SF, SM, SQ, SR, ST,U, V and Y Classes will also be Component Classes and will be apportioned into two or more Segments. EachSegment will have the original principal amount shown under ""Terms Sheet Ì Segments'' in this Supple-ment. Payments of principal made with respect to these Segments on any Payment Date will be aggregatedand then allocated as described under ""Terms Sheet Ì Allocation of Principal Ì Allocation of SegmentPrincipal Payments'' in this Supplement. Segments are not separate Classes and will not be separately issuedor transferable.

S-23

Amount of Payments

The total amount of principal payments that will be made on the Securities on each Payment Date willequal the sum of:

‚ the amount of interest, if any, accrued on the K Class during the related Accrual Period and notpayable as interest on that Payment Date (the ""K Accrual Amount'');

‚ the amount of interest, if any, accrued on the Z Class during the related Accrual Period and notpayable as interest on that Payment Date (the ""Z Accrual Amount'');

‚ the amount of interest, if any, accrued on the ZD Class during the related Accrual Period and notpayable as interest on that Payment Date (the ""ZD Accrual Amount'');

Retail Class Principal Payments

General

The QQ and UU Classes are Retail Classes. Freddie Mac has arranged to make principal payments oneach Retail Class in $1,000 increments. These arrangements are intended to accommodate retail investorswho may not wish to receive their principal payments in amounts smaller than $1,000, to give a limitedpayment priority to investors who request early payment, and to give the Ñrst limited payment priority to therequesting estates of deceased investors.

Principal payments on the Retail Classes will be made as follows:

‚ Freddie Mac will determine the amount of principal, if any, payable on each Retail Class (as awhole) on each Payment Date as described above.

‚ The principal payment on each Retail Class will be rounded to a multiple of $1,000 using theRetail Rounding Account, and the Registrar will pay the rounded amount to the RetailDepository.

‚ The Retail Depository will remit the principal payment for each Retail Class, in multiples of$1,000, to the applicable Retail Depository Participants. The Retail Depository Participants andother Ñnancial intermediaries in turn will remit principal payments to investors in each RetailClass, also in multiples of $1,000.

‚ Investors in each Retail Class who have properly requested early payment will be paid Ñrst, to theextent of available principal, with a Ñrst priority given to ""Deceased Owners'' of that Class and asecond priority to ""Living Owners'' of that Class.

‚ If more principal is available for payment on a Retail Class than the amount covered by validrequests for early payment, non-requesting investors in that Class will receive principal paymentsin multiples of $1,000 under procedures described below.

The rest of this section describes these procedures in more detail.

Rounding of Principal Payments

Whenever principal payments are to be made on a Retail Class, the amount allocable to that Class will berounded to a multiple of $1,000. On the Ñrst Payment Date when principal payments will be made on a RetailClass, the Registrar will withdraw from the Retail Rounding Account any funds needed to round the allocableamount upward to the next multiple of $1,000 and will pay the rounded amount on that Class. On the nextPayment Date when principal payments will be made on such Retail Class, the Registrar will apply theallocable amount Ñrst to repay any amount withdrawn for that Class from the Retail Rounding Account on theprevious Payment Date; then it will round the remainder of such allocable amount upward to the next multipleof $1,000, by making another withdrawal from the Retail Rounding Account, and will pay this amount to suchRetail Class. This process will continue on subsequent Payment Dates until such Retail Class has been retired.

Principal Payment Requests and Withdrawals

Any beneÑcial owner of Retail Class Units may request that any or all of such Units be paid in full on theearliest possible Payment Date. The beneÑcial owner must submit any request for Retail Class principalpayments to his or her broker or other Ñnancial intermediary, which must in turn make the request in writingto the Retail Depository. The Retail Depository will date and time stamp all requests in accordance with itsestablished procedures and forward the requests to the Registrar. The Registrar will maintain a list of thoseRetail Depository Participants representing beneÑcial owners that have requested Retail Class principalpayments, together with the order of receipt and the amounts of the requests. Investors can get informationregarding the number of Retail Class Units of the applicable Class for which requests have been made and thestatus of their own requests by writing the Registrar at Texas Commerce Bank National Association, 601Travis, 8TCT39, Houston, TX 77002.

S-41

A beneÑcial owner may withdraw a request for a Retail Class principal payment by notifying his or herbroker or other Ñnancial intermediary, which must in turn forward the notice of withdrawal in writing to theRegistrar. Any request for a Retail Class principal payment will be deemed withdrawn when the Registrarreceives notice of the beneÑcial owner's transfer of the related Retail Class Units.

In order for a request or a notice of withdrawal to be eÅective for any Payment Date, it must be receivedby the Retail Depository (in the case of a request) or the Registrar (in the case of a withdrawal) by the lastbusiness day of the preceding calendar month. Once eÅective, a request will remain eÅective for all PaymentDates unless it is withdrawn.

The Retail Depository will honor requests for Retail Class principal payments to be made on anyPayment Date in accordance with the procedures described below. The Registrar will notify the RetailDepository and the appropriate Retail Depository Participants which of the requests should be honored oneach Payment Date. The decisions of the Registrar and the Retail Depository concerning these matters, andany related rules and procedures they establish, will be binding on all aÅected persons.

Principal Payment Allocations

Payments to Requesting BeneÑcial Owners. For any Payment Date, priority of payment on each RetailClass will be given to beneÑcial owners of that Class for whom principal payment requests are in eÅect. TheRetail Depository will honor requests in the following order of priority:

First, the Retail Depository will honor requests submitted on behalf of Deceased Owners of a RetailClass in the order of their receipt by the Retail Depository, until such requests have been honored in anamount up to $100,000 for each requesting Deceased Owner of that Class; and

Second, the Retail Depository will honor requests submitted on behalf of Living Owners of a RetailClass in the order of priority established by the random lot procedures of the Registrar, until suchrequests have been honored in an amount up to $10,000 for each requesting Living Owner of that Class.

Thereafter, the Retail Depository will honor requests submitted on behalf of each Deceased Owner asprovided in step First up to a second $100,000, and requests submitted on behalf of each Living Owner asprovided in step Second up to a second $10,000. This sequence of priorities will be repeated until all principalpayment requests have been honored.

If the amount of principal available for payment on a Retail Class on a given Payment Date is insuÇcientto honor all requests, such requests will be honored on succeeding Payment Dates as principal becomesavailable. In the case of requests on behalf of Living Owners, the Registrar will establish a new order ofpriority for each Payment Date by random lot. This order will apply both to previously unsatisÑed paymentrequests and to newly submitted requests. A Retail Class principal payment request submitted on behalf of aLiving Owner who later dies will become entitled to the priority of a newly submitted request on behalf of aDeceased Owner. Such priority will be eÅective for each subsequent Payment Date, if the Retail Depositoryhas received appropriate evidence of death and any requested tax waivers by the last business day of thepreceding calendar month.

Payments to Non-Requesting BeneÑcial Owners. If the amount of principal available for payments on aRetail Class on a given Payment Date exceeds the amount needed to honor all principal payment requests, theRetail Depository will determine which Retail Class Units will be paid, using its established random lotprocedures. Each Retail Depository Participant receiving such payments, and each Ñnancial intermediary inthe chain to the beneÑcial owners, will remit payments to their customers according to their own procedures,which may or may not be by random lot. A Retail Depository Participant or Ñnancial intermediary coulddecide to allot Retail Class principal payments to certain customers (which could include such RetailDepository Participant or intermediary) without allotting payments to others. Investors may ask their brokersor other intermediaries what allocation procedures they use.

S-42

BeneÑcial Owners

A ""Deceased Owner'' is the estate of an individual who beneÑcially owned one or more Retail ClassUnits of the applicable Class at the time of death, provided the executor or other authorized representative ofthe estate furnishes to the Retail Depository evidence of death satisfactory to the Registrar and any tax waiversrequested by the Registrar. A ""Living Owner'' is any other beneÑcial owner of one or more Retail Class Unitsof the applicable Class.

The following rules will apply to determine beneÑcial ownership in the case of Deceased Owners:

‚ Retail Class Units beneÑcially owned by tenants by the entirety, joint tenants or tenants incommon will be regarded as beneÑcially owned by a single owner. The death of a tenant by theentirety, joint tenant or tenant in common will be deemed the death of the beneÑcial owner, andthe Retail Class Units beneÑcially owned will become eligible for the principal payment prioritydescribed above.

‚ Retail Class Units beneÑcially owned by a trust will be regarded as beneÑcially owned by eachbeneÑciary of the trust to the extent of that beneÑciary's interest in the trust (however, a trust'sbeneÑciaries collectively cannot be beneÑcial owners of more Retail Class Units than are ownedby the trust). The death of a beneÑciary of a trust will be deemed the death of a beneÑcial ownerof the Retail Class Units beneÑcially owned by the trust to the extent of that beneÑciary's interestin the trust.

‚ The death of an individual who was a tenant by the entirety, joint tenant or tenant in common in atenancy which is the beneÑciary of the trust will be deemed the death of the beneÑciary of thetrust.

‚ The death of a person who, during his or her lifetime, was entitled to substantially all of thebeneÑcial interest in a Retail Class Unit will be deemed the death of the beneÑcial owner of thatRetail Class Unit, regardless of the registration of ownership, if such beneÑcial interest can beestablished to the satisfaction of the Registrar. Such beneÑcial interest will exist in many cases ofstreet name or nominee ownership, ownership by a trustee, ownership under the Uniform Gifts toMinors Act and community property or other joint ownership arrangements between spouses.BeneÑcial interest will be evidenced by such factors as the power to sell or otherwise dispose of aRetail Class Unit, the right to receive the proceeds of sale or disposition and the right to receiveinterest and principal payments on a Retail Class Unit.

Class Factors

Description of Factors

On or about the Ñrst business day of each month after the Closing Date in the case of the Regular Classesof Multiclass PCs and related MACR Classes, and on or about the ninth business day of each month after theClosing Date in the case of the Regular Classes of Multiclass Securities and related MACR Class, FreddieMac will make available (including on its Internet Web-Site) a Class Factor for each Class having a principalamount. The Class Factor for any Class for any month will be a truncated seven-digit decimal which, whenmultiplied by the original principal amount of a Security of that Class (assuming such Class was issued on theClosing Date), will equal its remaining principal amount, after giving eÅect to any principal payment (oraddition to principal) to be made on the Payment Date in the same month. The Class Factor for an AccrualClass will also reÖect any addition to its principal amount to be made on the same Payment Date. Forexample, the January Class Factor for any Class will reÖect the remaining principal amount of a Security ofthat Class, after giving eÅect to any principal payment (or addition to principal) to be made on January 15 orJanuary 25, as applicable. Freddie Mac will also make available a Class Factor for each Notional Class, whichwill reÖect the remaining notional principal amount of a Security of that Class in an analogous manner. TheClass Factor for a Retail Class will apply to that Class as a whole, not to individual Retail Class Units, and willdisregard any rounding of principal payments. The Class Factor for each Class for the month of the ClosingDate is 1.0000000.

S-43

Component Factors for each Component will be available from Freddie Mac's Internet Web-Site or uponrequest by writing or calling the Investor Inquiry Department at Freddie Mac at the address or phone numbersshown under ""Available Information'' in this Supplement. The Component Factor for a Component isanalogous to the Class Factor for a Class.

Regular Classes of Multiclass Securities and Related MACR Class

The Class Factors for the Regular Classes of Multiclass Securities and related MACR Class will reÖectFreddie Mac's published Class Factors for their related Asset or Assets, which will be based in part onpreliminary GNMA CertiÑcate factors or, in some cases, on Freddie Mac's own calculation of assumedMortgage amortization schedules, and may not reÖect payments actually received on the underlying GNMACertiÑcates in a given month. See ""Description of Multiclass Securities Ì Class Factors'' in the MulticlassSecurities OÅering Circular and ""Description of Pass-Through Securities Ì Payments Ì Class Factors'' inthe Giant Securities OÅering Circular.

Use of Factors

For any Payment Date, investors can calculate the reduction (or for an Accrual Class, the increase) inthe principal amount of a Security of any Class entitled to principal payments by multiplying the originalprincipal amount of that Security by the diÅerence between its Class Factors for the preceding and currentmonths. The amount of interest to be paid on (or added to the principal amount of) a Security of any Class oneach Payment Date will equal 30 days' interest on its outstanding principal amount (or notional principalamount) as determined by its Class Factor for the preceding month, plus additional interest on certainCallable Classes in the case of a redemption of the related Callable Asset. See ""General Information ÌStructure of Transaction Ì The Callable Assets'' in this Supplement.

For example, the reduction (or for an Accrual Class, the increase) in the principal amount of anySecurity entitled to principal payments in February will reÖect the diÅerence between its January andFebruary Class Factors. The amount of interest to be paid on (or added to the principal amount of) anySecurity in February (other than upon a redemption of a Callable Asset) will equal 30 days' interest at itsClass Coupon, accrued during the month of January (in the case of a Fixed Rate, Delay, Ascending Rate orDescending Rate Class) or from January 15 or 25 to February 15 or 25 (in the case of a Non-Delay Class), onthe principal amount or notional principal amount of such Security determined by its January Class Factor. Ifthe outstanding balance of any Fixed Rate, Delay, Ascending Rate or Descending Rate Class is reduced onthe Payment Date that falls within an Accrual Period, that Class will accrue interest during such AccrualPeriod on its reduced balance, even though its balance had been higher for approximately the Ñrst 15 or 25days of the Accrual Period. No interest at all will be paid on any Class (or on any Retail Class Unit) after itsbalance has been reduced to zero.

Guarantees

Freddie Mac guarantees to each Holder of a Security (i) the timely payment of interest at the applicableClass Coupon and (ii) the payment of the principal amount of the Holder's Security as described in thisSupplement. See ""Description of Multiclass PCs Ì Guarantees'' in the Multiclass PC OÅering Circular and""Description of Multiclass Securities Ì Guarantees'' in the Multiclass Securities OÅering Circular.

Freddie Mac also guarantees the payment of interest and principal on the Assets, Gold PCs, Gold GiantPCs and Giant Securities. See ""PC Security Structure Ì Guarantees'' in the PC OÅering Circular and""Description of Pass-Through PCs Ì Guarantees'' in the Giant PC OÅering Circular and ""Description ofPass-Through Securities Ì Guarantees'' in the Giant Securities OÅering Circular.

GNMA guarantees the timely payment of principal and interest on the GNMA CertiÑcates. Theobligations of GNMA under its guarantees of the GNMA CertiÑcates are backed by the full faith and creditof the United States.

S-44

Optional Redemption

A Callable Asset may be redeemed on any Payment Date beginning in September 1998 at the option ofthe holder of the related Call Class in Series C057. The redemption of a Callable Asset would result in theconcurrent retirement of all related Regular Classes then outstanding and the RA or RB Class, as applicable.See ""Payments Ì Redemption and Exchange'' in the Callable Asset OÅering Circular and ""GeneralInformation Ì Structure of Transaction Ì The Callable Assets'' and ""Prepayment and Yield Analysis ÌYield Considerations Ì Prepayments and Redemption: EÅect on Yields'' in this Supplement.

Freddie Mac may redeem the RA, RB or RC Class and its related Mortgage Securities, in whole but notin part, on any Payment Date when their aggregate outstanding principal amount would be less than 1% oftheir aggregate original principal amount. Upon any redemption, the redemption price of such MortgageSecurities will be applied to retire the related Regular Classes that remain outstanding. Any outstandingMACR Classes will be retired from the proceeds of any redemption of their related Regular Classes. TheMulticlass Assets other than the Group 5 and Group 11 Assets may become subject to similar optionalredemption provisions applicable to their respective Series. Freddie Mac will not exercise its right ofredemption as to a Lower-Tier REMIC Pool containing a Callable Asset if the Callable Asset is to beredeemed. The Group 5 and Group 11 Assets and the PCs and the GNMA-Related Securities are notredeemable. See ""Description of Multiclass PCs Ì Optional Redemption'' in the Multiclass PC OÅeringCircular and ""Description of Multiclass Securities Ì Optional Redemption'' in the Multiclass SecuritiesOÅering Circular.

Residual Proceeds

Upon surrender of their certiÑcates to the Registrar, the Holders of the RA, RB or RC Class will receivethe proceeds of the remaining assets of the related Lower-Tier REMIC Pool after all required principal andinterest payments on the related Mortgage Securities have been made. Any such remaining assets are notlikely to be signiÑcant.

Upon like surrender, the Holders of the R Class will receive the proceeds of the remaining assets of theUpper-Tier REMIC Pool (including the Retail Rounding Account) after all required principal and interestpayments on the Regular Classes and the R Class have been made. Any such remaining assets are not likely tobe signiÑcant.

PREPAYMENT AND YIELD ANALYSIS

General

Mortgage Prepayments

The rates of principal payments on the PC Assets and Callable Assets will depend directly, and the ratesof payments on the Multiclass Assets and the Securities will depend indirectly, on the rates of principalpayments on the related Mortgages. Mortgage principal payments may be in the form of scheduledamortization or partial or full prepayments. ""Prepayments'' include prepayments by the borrower, liquidationsresulting from default, casualty or condemnation and payments made by Freddie Mac or GNMA, asapplicable, pursuant to its guarantee of principal (other than scheduled amortization) on PCs or GNMACertiÑcates. The Mortgages are subject to prepayment at any time without penalty.

Mortgage prepayment rates are likely to Öuctuate signiÑcantly. In general, when prevailing mortgageinterest rates decline signiÑcantly below the interest rates on the Mortgages, the prepayment rate on theMortgages is likely to increase, although a number of other factors also may inÖuence the prepayment rate.See ""Prepayments, Yields and Suitability'' in the PC OÅering Circular.

Acceleration of mortgage payments as a result of transfers of mortgaged properties is an important factoraÅecting prepayment rates. The Mortgages underlying PCs generally provide that, in the event of the transferor prospective transfer of the underlying mortgaged property, the full unpaid principal balance is due andpayable at the option of the holder. Freddie Mac, in most cases, requires mortgage servicers to enforce such""due-on-transfer'' provisions where permitted by applicable law. See ""The Mortgages Ì Mortgage Purchase

S-45

and Servicing Standards Ì Mortgage Servicing Ì Assumption and Due-on-Transfer Policies'' in the PCOÅering Circular.

None of the Mortgages underlying GNMA CertiÑcates includes a ""due-on-transfer'' clause. Conse-quently, the holder of such a Mortgage generally may not demand the payment in full of the remainingprincipal balance of that Mortgage on the sale or other transfer of the mortgaged property to a creditworthytransferee.

Information on the principal payment history of the PCs, Giant Securities and Assets is available fromthe Investor Inquiry Department at Freddie Mac at the address or phone numbers shown under ""AvailableInformation'' in this Supplement. However, historical payment experience is not likely to be indicative offuture payment experience on the PCs, Giant Securities, Assets and related Mortgages.

PSA Model

Prepayments on pools of mortgages are commonly measured relative to a variety of prepayment models.The particular model used in this Supplement, ""PSA,'' is the standard prepayment model of PSA The BondMarket Trade Association. This model assumes that mortgages will prepay at an annual rate of 0.2% in theÑrst month after origination, that the prepayment rate increases at an annual rate of 0.2% per month up to the30th month after origination and that the prepayment rate is constant at 6% per annum in the 30th and latermonths (this assumption is called ""100% PSA''). For example, at 100% PSA, mortgages with a loan age ofthree months (i.e., mortgages in their fourth month after origination) are assumed to prepay at an annual rateof 0.8%. ""0% PSA'' assumes no prepayments; ""50% PSA'' assumes prepayment rates equal to 0.50 times100% PSA; ""200% PSA'' assumes prepayment rates equal to 2.00 times 100% PSA; and so forth. PSA is not adescription of historical prepayment experience or a prediction of the rate of prepayment of the Mortgages.

Weighted Average Life

The weighted average life of a security refers to the average amount of time that will elapse from the dateof its issuance until each dollar of principal has been repaid to the investor. The weighted average lives of theClasses will depend primarily on the rate at which principal is paid on the related Mortgages and, in the caseof the Callable Classes, whether a redemption of the related Callable Asset occurs. This Supplement showsweighted average lives under various Mortgage prepayment assumptions and redemption assumptions, ifapplicable. In each case, Freddie Mac has calculated the weighted average life by (i) multiplying the assumednet reduction, if any, in the principal amount on each Payment Date by the number of years from the ClosingDate to such Payment Date, (ii) summing the results and (iii) dividing the sum by the aggregate amount ofthe assumed net reductions in principal amount.

Yield

The yield of each Class will depend upon its purchase price, its sensitivity to the rate of payments on therelated Asset or Assets (which will be sensitive to the rate of principal payments on the related Mortgages),the manner in which payments are allocated to the related Asset or Assets, the actual characteristics of therelated Mortgages and, in the case of the Callable Classes, whether a redemption of the related Callable Assetoccurs. In the case of a Retail Class, the yield of a particular Retail Class Unit will also depend upon the dateon which it is retired as a result of the priorities, limitations and allocations described under ""Payments ÌRetail Class Principal Payments'' in this Supplement. The yield of each Floating Rate or Inverse FloatingRate Class will also depend on its sensitivity to the level of the applicable Index. This Supplement shows pre-tax yields to maturity under various scenarios. In each case, Freddie Mac has calculated the pre-tax yield by(i) determining the monthly discount rate (whether positive or negative) that, when applied to an assumedstream of cash Öows to be paid on the applicable Class, would cause the discounted present value of suchassumed stream of cash Öows to equal an assumed purchase price (including accrued interest, if any) of thatClass and (ii) converting such monthly rate to a corporate bond equivalent (i.e., semiannual payment) rate.The yield calculations do not take into account any variations in the interest rates at which investors may beable to reinvest payments received. Consequently, they do not reÖect the return on any investment whenreinvestment rates other than the discount rate are considered.

S-46

Modeling Assumptions

In order to prepare the various tables and other statistical information in this Supplement, Freddie Machas made certain assumptions regarding the underlying Mortgages. Unless otherwise noted, each table isbased on the following assumptions (the ""Modeling Assumptions''), among others:

‚ The Mortgages underlying the PC Assets and Callable Assets have the assumed characteristicsshown under ""Terms Sheet Ì Mortgage Characteristics'' in this Supplement;

‚ As of September 1, 1997, each Mortgage underlying the Multiclass Assets has a remaining termto maturity equal to the weighted average remaining term to maturity, a loan age equal to theweighted average loan age, and an interest rate equal to the weighted average interest rate, of allthe Mortgages underlying the same PC or GNMA-Related Security;

‚ As of the Closing Date, the Assets have the principal or notional principal balances shown under""Terms Sheet Ì The Assets'' in this Supplement;

‚ Payments on the Callable Assets and Multiclass Assets are made as described in the AssetOÅering Circulars;

‚ Payments on the Group 5 and Group 14 Classes and their underlying Assets are always receivedon the 25th of the month, whether or not a Business Day;

‚ Payments on the other Classes and their underlying Assets are always received on the 15th of themonth, whether or not a Business Day;

‚ Except as otherwise noted, no redemption of a Callable Asset occurs;

‚ Freddie Mac does not make an optional redemption;

‚ Principal payments on the Retail Classes are not rounded to multiples of $1,000; and

‚ Each Class is held from the Closing Date to retirement and is not exchanged in whole or in part.

When reading the tables and the related text, investors should bear in mind that the ModelingAssumptions, like any other stated assumptions, are unlikely to be entirely consistent with actual experience.For example, most of the Mortgages do not have the characteristics assumed, many Payment Dates will occuron the Ñrst Business Day after the 15th or 25th of the month, a redemption of a Callable Asset may occur andFreddie Mac may make an optional redemption as described under ""Payments Ì Optional Redemption''above.

In addition, payments on the Group 5 and Group 14 Classes will depend in part on preliminary GNMACertiÑcate factors and, in some cases, on Freddie Mac's own calculations of assumed Mortgage amortizationschedules, both of which may not reÖect payments actually received on the GNMA CertiÑcates in a givenmonth. See ""Payments Ì Class Factors'' in this Supplement and ""Description of Multiclass Securities ÌClass Factors'' in the Multiclass Securities OÅering Circular.

Principal Payment Stability

Mortgages and mortgage securities, such as the Assets and Securities, are subject to prepaymentuncertainty. The rates of principal payments on the PC Assets and Callable Assets will depend directly, andthe rates of payments on the Multiclass Assets and the Securities will depend indirectly, on the rates ofprincipal payments on their related Mortgages. In addition, the redemption of a Callable Asset, which mayoccur on any Payment Date beginning in September 1998, would result in the concurrent retirement of all therelated Callable Classes then outstanding. However, within certain limits, some Classes of Securities, such asthe PAC Classes, are expected to exhibit a lower level of prepayment uncertainty than the related Mortgagesand Assets. Such Classes are said to have a degree of ""stability.'' Stability in one Class or group of Classes isnecessarily oÅset by instability in other Classes, such as the Support Classes, which are said to ""support'' themore stable Classes.

Suitability

The Securities, especially the Inverse Floating Rate, Interest Only, Principal Only, Callable, Support,Component, Accrual and Residual Classes are not suitable investments for all investors. The Securities are notappropriate investments for any investor that requires a single lump sum payment on a predetermined date oran otherwise certain payment stream. In addition, although the Underwriter intends to make a market for the

S-47

purchase and sale of the Securities after their initial issuance, it has no obligation to do so. There is noassurance that such secondary market will develop, that any secondary market will continue, or that the priceat which an investor can sell an investment in any Class will enable the investor to realize a desired yield onthat investment. The market values of the Classes are likely to Öuctuate; such Öuctuations may be signiÑcantand could result in signiÑcant losses to investors. The secondary markets for mortgage-related securities haveexperienced periods of illiquidity and can be expected to do so in the future. Illiquidity can have a severelyadverse eÅect on the prices of Classes that are especially sensitive to prepayment, redemption or interest raterisk or that have been structured to meet the investment requirements of limited categories of investors.Investors are encouraged to consult their own advisors regarding the Ñnancial, legal, tax and other aspects ofan investment in the Securities. The Öexibility created by the ability to modify and combine certain Classes ofMulticlass PCs or Multiclass Securities and related MACR Classes may aÅect the liquidity of the Classes andthe prices that potential purchasers are willing to pay in the secondary market. In addition, the redemptionfeature of the Callable Assets may aÅect the market values of the Callable Classes. No investor shouldpurchase Securities of any Class unless the investor understands and is able to bear the prepayment,redemption, yield, liquidity and market risks associated with that Class.

Prepayment and Weighted Average Life Considerations

PAC Classes, Component and Segments

Payments of principal on the PAC Classes, Component and Segments are likely to be relatively stablebecause they will receive principal payments in accordance with their schedules, so long as prepayments onthe related Mortgages occur at rates that are neither too fast nor too slow to support their schedules.Moreover, the PAC Classes, Component and Segments will have cumulative priorities for future payments ifthey fall behind their schedules. For each PAC Class, Component or Segment, there is a range of constantMortgage prepayment rates (an ""EÅective Range'') at which such Class, Component or Segment wouldreceive scheduled payments. The EÅective Range at any time depends on the actual or assumed characteris-tics of the related Mortgages at that time. Based on the Modeling Assumptions, each PAC Class, Componentor Segment shown in the following table would receive scheduled payments if the related Mortgages were toprepay at any constant percentage of PSA within its initial EÅective Range shown below, until that Class,Component or Segment has been retired.

* The schedules for the Classes, Component and Segments shown were prepared by calculating the amounts that would beavailable for payments of principal on those Classes, Component and Segments using, among other things, the ModelingAssumptions and the ""structuring ranges'' shown under ""Terms Sheet Ì Allocation of Principal'' in this Supplement.

The underlying Mortgages will have characteristics that diÅer from those of the Modeling Assumptions.The initial EÅective Ranges, if calculated using the actual characteristics of the Mortgages, could diÅer fromthose shown in the table. Therefore, even if the Mortgages were to prepay at a constant rate within the initialEÅective Range shown for any Class, Component or Segment, but near its upper or lower end, that Class,Component or Segment could fail to receive scheduled payments.

Moreover, the Mortgages will not prepay at any constant rate. Non-constant prepayment rates can causeany PAC Class, Component or Segment not to receive scheduled payments, even if such rates remain withinits initial EÅective Range. The EÅective Range for any PAC Class, Component or Segment can narrow or""drift'' upward or downward over time.

The principal payment stability of the Group 6 PAC Classes and Segment will be supported in part by theGroup 6 Support Class and Segment. The principal payment stability of the Group 9 Type IA PAC Class andSegment will be supported in part by the Group 9 Type IB PAC and Support Classes and the Type IB PACand TAC Segments. The principal payment stability of the Group 9 Type IB PAC Classes and Segment willbe supported in part by the Group 9 Support Class and the TAC Segment. The principal payment stability ofthe Group 10 PAC Classes, Component and Segment will be supported in part by the Group 10 SupportClasses, Component and Segment. The principal payment stability of the Group 15 PAC Classes andSegment will be supported in part by the Group 15 Support Class and Segment. When its supportingClass(es), Component or Segment(s) are retired, any outstanding PAC Class, Component or Segment will nolonger have an EÅective Range and will become more sensitive to Mortgage prepayments.

S-49

If the underlying Mortgages prepay at rates that are generally below the EÅective Range for any PACClass, Component or Segment, the available principal may be insuÇcient to generate scheduled payments onthat Class, Component or Segment and its weighted average life may be extended, perhaps signiÑcantly. If theunderlying Mortgages prepay at rates that are generally above the EÅective Range for any PAC Class,Component or Segment, its weighted average life may be shortened, perhaps signiÑcantly. However, theweighted average lives of one or more of the PAC Classes, Component and Segments could be extended undercertain scenarios involving Mortgage prepayments at rates that are generally above their EÅective Ranges.

The entire Group 6, Group 9, Group 10 and Group 15 Asset Principal Amounts will be distributedmonthly on each Payment Date and will not be retained for distribution on subsequent Payment Dates. Thus,the likelihood that the PAC Classes, Component and Segments will receive scheduled payments will not beenhanced by averaging high and low principal payments in diÅerent months.

TAC Segments

Payments of principal on the TAC Segments are expected to be more stable than would be the case if theTAC Segments were not entitled to receive payments, to the extent of available principal, according to theirschedules of Targeted Balances. Based on the Modeling Assumptions, the TAC Segments would adhere totheir schedules if the underlying Mortgages were to prepay at constant rates of 170% PSA (in the case ofSegment 5) and 152% PSA (in the case of Segments 8 and 11) until they have been retired. However,because the characteristics of the Mortgages will diÅer from those assumed and because the Mortgages willnot prepay at such rates or any other constant rate, it is not likely that the TAC Segments will consistentlyadhere to their schedules.

The principal payment stability of Segment 5 will be supported in part by the ZD Class. The principalpayment stability of Segment 8 will be supported in part by the Y Class. The principal payment stability ofSegment 11 will be supported in part by the FM and SM Classes. When its supporting Class or Classes areretired, any outstanding TAC Segment will become more sensitive to Mortgage prepayments.

Based on the Modeling Assumptions, if the underlying Mortgages prepay at rates that are generally belowapproximately 170% PSA (in the case of Segment 5) or 152% PSA (in the case of Segments 8 and 11), theGroup 9 Asset Principal Amount, the Group 10 Asset Principal Amount or the Group 15 Asset PrincipalAmount, as applicable, may be insuÇcient to reduce the applicable TAC Segment to its Targeted Balance andits weighted average life may be extended, perhaps signiÑcantly. Based on the Modeling Assumptions, if theunderlying Mortgages prepay at rates that are generally above approximately 170% PSA (in the case ofSegment 5) or 152% PSA (in the case of Segments 8 and 11), the weighted average life of the applicableTAC Segment may be shortened, perhaps signiÑcantly. However, the weighted average lives of the TACSegments could be extended under certain scenarios involving Mortgage prepayments at rates that aregenerally above approximately 170% PSA (in the case of Segment 5) and 152% PSA (in the case ofSegments 8 and 11).

As is the case with the PAC Classes, Component and Segments, the likelihood that the TAC Segmentswill adhere to their schedules will not be enhanced by averaging high and low principal payments in diÅerentmonths.

Support Classes, Component and Segments

The Support Classes, Component and Segments will support the principal payment stability of therelated PAC and TAC Classes, Component and Segments, as described above. Thus, each Support Class,Component and Segment is likely to be much more sensitive to Mortgage prepayments than is any Class,Component or Segment it supports. The Support Classes, Component and Segments may receive no principalpayments for extended periods of time and may receive principal payments that vary widely from period toperiod. Relatively fast Mortgage prepayments may signiÑcantly shorten, and relatively slow Mortgageprepayments may signiÑcantly extend, the weighted average lives of the Support Classes, Component andSegments.

Component Classes

The FO Class consists of a PAC Component and, primarily, a Support Component. The principalpayment characteristics of the FO Class will be generally similar to those of Support Classes. The principalpayment characteristics of the Component Classes that constitute Segments are described under ""PAC

S-50

Classes, Component and Segments,'' ""TAC Segments'' and ""Support Classes, Component and Segments''above. DiÅerent Classes within any given Segment are likely to exhibit diÅerent degrees of sensitivity toprepayment rates on the related Mortgages.

Sequential Pay Classes

As described above, the Sequential Pay Classes will receive principal payments from the Group 1 Assetor Group 7 Asset, as applicable, in a prescribed sequence. While it is receiving such principal payments, thesensitivity of each Sequential Pay Class to prepayments on the underlying Mortgages will be approximatelythe same as that of its related Asset. The Sequential Pay Classes are also Callable Classes; if any CallableClass is redeemed, its weighted average life will be reduced, perhaps signiÑcantly.

Pass-Through Classes

Each Pass-Through Class will receive all or a speciÑed portion of the principal payments made on itsrelated Asset or Assets on each Payment Date. The sensitivity of a Pass-Through Class to prepayments on itsrelated Mortgages will reÖect that of the related Asset or Assets.

Retail Classes

Principal payments on each Retail Class will depend upon the prepayment rate on the underlyingMortgages. As a result, it is uncertain when principal payments on either Retail Class will begin, at what rateprincipal payments on either Retail Class will be made and when either Retail Class will be retired. Underextremely fast and highly unlikely prepayment scenarios, some investors' Retail Class Units could be retiredon the Ñrst Payment Date. On the other hand, some investors' Retail Class Units could be retired as late as theFinal Payment Date for the related Retail Class.

The amount of principal available for payment on a Retail Class on any given Payment Date will belimited. Thus, an investor's request for a Retail Class principal payment may not be honored until well after itssubmission. The likelihood that any Living Owner's request can be honored within any particular time aftersubmission will depend in part on the number of Retail Class Units of the same Class beneÑcially owned byinvestors who have a prior right of payment because they are Deceased Owners and on the number of RetailClass Units of the same Class owned by other Living Owners who have submitted requests. Conversely, theamount of principal available for payment on a Retail Class on any given Payment Date could exceed theamount necessary to honor all requests. In that case, some investors will receive principal payments they didnot request.

When prevailing interest rates are higher than the Class Coupon of a Retail Class, a greater number ofinvestors in that Class can be expected to request Retail Class principal payments. At the same time, however,Mortgage prepayment rates are likely to decline (and a redemption of the related Callable Asset is less likelyto occur), reducing the funds available for Retail Class principal payments. Conversely, Mortgage prepaymentrates are likely to accelerate (and a redemption of the related Callable Asset will become more likely) whenprevailing interest rates decline, while investors may be less likely to request Retail Class principal payments.Investors whose Retail Class Units are selected for payment under such conditions may not be able to reinvesttheir payments at rates as high as the Class Coupon of the related Retail Class.

The following tables show the amounts that would be available for principal payments on the RetailClasses during the twelve-month periods indicated at various constant percentages of PSA. Freddie Mac hasprepared these tables based on the Modeling Assumptions, including the assumption that no redemption ofthe related Callable Asset occurs. Because Retail Class investors will receive principal payments in multiplesof $1,000 subject to the priorities, limitations and allocations described above, there is no assurance that anyinvestor will receive a principal payment on any particular date.

The Mortgages will not prepay at any constant rate until maturity. Moreover, the Mortgages havecharacteristics that diÅer from those of the Modeling Assumptions. Therefore, the amounts available forpayments of principal on a Retail Class during any twelve-month period are likely to diÅer in many cases fromthe amounts shown in its table.

The weighted average lives of each Retail Class shown in the declining balances table below apply to thatClass as a whole; as a result of the priorities, limitations and allocations described above, the weighted averagelives of the Retail Class Units owned by individual investors will vary (and may vary signiÑcantly) from theweighted average life of the related Retail Class. Freddie Mac can give no assurance regarding the weightedaverage life of a Retail Class as a whole, much less the weighted average life of any particular Retail ClassUnit.

MACR Classes

The principal payment characteristics of each MACR Class will reÖect the principal payment character-istics of the Classes of Multiclass PCs or Multiclass Securities which are combined to form such MACRClass.

S-53

The Callable Assets

Each Callable Asset is a Callable Class entitled to receive all of the interest and principal payments on itsunderlying Giant PC. Unless it is redeemed, the sensitivity of a Callable Asset to Mortgage prepayments willbe the same as that of its underlying PCs. A Callable Asset may be redeemed on any Payment Date beginningin September 1998, as described under ""Payments Ì Redemption and Exchange'' in the Callable AssetOÅering Circular and ""General Information Ì Structure of Transaction Ì The Callable Assets'' in thisSupplement.

See ""Prepayment and Yield Analysis'' in the Callable Asset OÅering Circular.

The Multiclass Assets

The Group 5 Assets are PAC Classes in Series G021, and the Group 11 Asset is a Type I PAC Class inSeries 1468. Such PAC Classes and Type I PAC Class are scheduled to receive principal payments beginningSeptember 25, 2002 and June 15, 2006, respectively. However, there is no assurance that either the Group 5Assets or the Group 11 Asset will receive principal payments in accordance with their respective schedules forall periods in the future. Moreover, no assurance can be given regarding the rate of reduction in the principalamount of the Group 5 Assets or the Group 11 Asset or the related Classes of this Series.

The Group 2 and Group 12 Assets are Scheduled Classes in Series 1727, the Group 3, Group 4 andGroup 13 Assets are TAC Classes in Series 1727, Series 1671 and Series 1671, respectively, and the Group 8Assets are Type III PAC Classes in Series 1671. Such Assets were structured to receive principal payments inaccordance with schedules. Currently, there is no constant rate or range of prepayments at which any suchAsset would adhere to its schedule. The principal payment stability of each such Asset is supported by certainother classes in its Series. When those other classes are retired, each such Asset, if outstanding, will becomemore sensitive to Mortgage prepayments. There can be no assurance that any such Asset will receive principalpayments in accordance with its schedule.

The Group 14 Asset is a Notional Class whose notional principal amount reduces proportionately withthe Strip Class in Series G021. The principal payment stability of such Strip Class is approximately the sameas the underlying GNMA-Related Securities. Therefore, the rate of reduction in the notional principalbalance of the Group 14 Asset is approximately the same as the rate of reduction of such GNMA-RelatedSecurities.

See ""Prepayment and Yield Analysis Ì Prepayment and Weighted Average Life Considerations'' in therelated Asset OÅering Circulars.

Declining Balances Table

The following table shows, for the indicated Classes of Securities and the underlying Assets, (i) thepercentages of their original principal or notional principal amounts (or, in the case of the Assets, theiroutstanding principal or notional principal amounts as of the Closing Date) that would be outstanding aftereach of the dates shown at various constant percentages of PSA, assuming, in the case of the Callable Classes,that no redemption of the related Callable Asset occurs and (ii) except in the case of the Group 14 Asset andrelated Classes, their corresponding weighted average lives, assuming, in the case of the Callable Classes,either that no redemption of the related Callable Asset occurs or that a redemption occurs on one of thePayment Dates shown. Freddie Mac has prepared this table using the Modeling Assumptions. However, for0% PSA, Freddie Mac has assumed that each Mortgage underlying the PC Assets or Callable Assets bearsinterest at a per annum rate of 2.5% above that of such Assets and has a remaining term to maturity of360 months or 180 months, as applicable, and a loan age of 0 month. The Mortgages do not have thecharacteristics assumed, and Mortgage prepayment rates may diÅer from the constant rates shown. ThesediÅerences may aÅect the actual payment behavior and weighted average life of any Class or Asset. Forexample, because of the diverse remaining terms to maturity, loan ages and interest rates of the Mortgages,principal payments on any Class or Asset may be faster or (except at 0% PSA in the case of the PC Assets,Callable Assets and related Classes) slower than indicated, even if the Mortgages were to prepay at theconstant rates shown. This may be the case even if the weighted average remaining term to maturity, weightedaverage loan age and weighted average interest rate of the Mortgages are the same as those of mortgageshaving the characteristics assumed.

Yield Considerations

An investor seeking to maximize yield should make a decision whether to invest in any Class based on theanticipated yield of that Class resulting from its purchase price, the investor's own projection of Mortgageprepayment rates and Asset payment rates under a variety of scenarios, the investor's own projection of thelikelihood of a redemption of the related Callable Asset (if applicable) under a variety of scenarios and, in thecase of the Floating Rate and Inverse Floating Rate Classes, the investor's own projection of levels of theapplicable Index under a variety of scenarios. Freddie Mac makes no representation regarding Mortgageprepayment rates, Asset payment rates, the likelihood of a redemption of the Callable Assets, the level ofeither Index or the yield of any Class.

Prepayments and Redemption: EÅect on Yields

The yields to investors will be sensitive in varying degrees to the rate of prepayments on the underlyingMortgages and, in the case of the Callable Classes, to the occurrence of a redemption of the related CallableAsset. In the case of the Interest Only Classes and any other Classes purchased at a premium over theirprincipal amounts, faster than anticipated rates of Mortgage principal payments or a redemption of the relatedCallable Asset, if applicable, could result in actual yields to investors that are lower than the anticipated yields.Investors in such Classes (especially the Interest Only and Callable Classes) should also consider the risk thatrapid rates of Mortgage principal payments or such a redemption, if applicable, could result in the failure ofinvestors to fully recover their investments. In the case of the Principal Only Classes and any other Classespurchased at a discount to their principal amounts, slower than anticipated rates of principal payments and theabsence of a redemption of the related Callable Asset, if applicable, could result in actual yields to investorsthat are lower than the anticipated yields.

Each Callable Asset may be redeemed by Freddie Mac at the direction of the holder of the related CallClass of Series C057 on any Payment Date beginning in September 1998 if, as of the date Freddie Macreceives notice of intention to redeem, the market value of the Giant PC underlying such Callable Assetexceeds its principal amount. A redemption of a Callable Asset would result in the concurrent retirement of allrelated Callable Classes then outstanding and would decrease the weighted average lives of such Classes,perhaps signiÑcantly. The earlier after the Closing Date that a redemption occurs, the greater would be sucheÅect.

In general, a redemption of a Callable Asset is most likely to occur if prevailing interest rates havedeclined. However, the holder of a Call Class, which may include the Underwriter (or an aÇliate), may alsobe a Holder of one or more related Callable Classes, such as an Interest Only Class, which may aÅect suchholder's decision whether to direct or not to direct the redemption of the related Callable Asset. Such investormay have an economic incentive to direct or not to direct the redemption of the related Callable Asset forreasons independent of the market value of the underlying Giant PC. For example, if the holder of a Call Classalso holds a related Interest Only Class, such holder may have an incentive not to exercise the redemptionoption, even if the underlying Giant PC has a market value above its principal amount. The eÅect of aredemption of a Callable Asset upon interest payments on the related Callable Classes is discussed under""General Information Ì Structure of Transaction Ì The Callable Assets'' in this Supplement.

Rapid rates of prepayments on the Mortgages (or a redemption of a Callable Asset) are likely to coincidewith periods of low prevailing interest rates. During such periods, the yields at which an investor may be ableto reinvest amounts received as principal payments on the investor's Class may be lower than the yield on thatClass. Conversely, slow rates of prepayments on the Mortgages (and the absence of a redemption of a CallableAsset) are likely to coincide with periods of high prevailing interest rates. During such periods, the amount ofprincipal payments available to an investor for reinvestment at such high rates may be relatively low.

The Mortgages will not prepay at any constant rate until maturity, nor will all of the Mortgages prepay atthe same rate at any one time. The timing of changes in the rate of prepayments may aÅect the actual yield toan investor, even if the average rate of principal prepayments is consistent with the investor's expectation. Ingeneral, the earlier a prepayment of principal on the Mortgages, the greater the eÅect on an investor's yield. Asa result, the eÅect on an investor's yield of principal prepayments occurring at a rate higher (or lower) than

S-70

the rate anticipated by the investor during the period immediately following the Closing Date is not likely tobe oÅset by a later equivalent reduction (or increase) in the rate of principal prepayments.

The Indices: EÅect on Yields of the Floating Rate and Inverse Floating Rate Classes

Investors in the Floating Rate Classes should consider the risk that lower than anticipated levels ofLIBOR could result in actual yields to investors that are lower than the anticipated yields and the fact thattheir Class Coupons cannot exceed their speciÑed maximum rates. Conversely, investors in the InverseFloating Rate Classes should consider the risk that higher than anticipated levels of the applicable Index couldresult in actual yields to investors that are signiÑcantly lower than the anticipated yields and the fact that theirClass Coupons can fall as low as 0%. Further, high levels of the applicable Index (especially in combinationwith fast Mortgage prepayment rates) may result in the failure of investors in the Inverse Floating RateClasses that are also Interest Only Classes to fully recover their investments.

Changes in either Index may not correlate with changes in mortgage interest rates. It is possible thatlower prevailing mortgage interest rates (which would be expected to result in faster prepayments) couldoccur concurrently with a higher level of either Index. Conversely, higher prevailing mortgage interest rates(which would be expected to result in slower prepayments) could occur concurrently with a lower level ofeither Index.

Neither Index will remain constant at any level. The timing of changes in the level of the applicableIndex may aÅect the actual yield to an investor, even if the average level is consistent with the investor'sexpectation. In general, the earlier a change in the level of the applicable Index, the greater the eÅect on aninvestor's yield. As a result, the eÅect on an investor's yield of an Index level that is higher (or lower) than therate anticipated by the investor during earlier periods is not likely to be oÅset by a later equivalent reduction(or increase).

Payment Delay: EÅect on Yields of Fixed Rate, Delay, Ascending Rate and Descending Rate Classes

The eÅective yield on any Fixed Rate, Delay, Ascending Rate or Descending Rate Class will be less thanthe yield otherwise produced by its Class Coupon and purchase price because (i) on the Ñrst Payment Date30 days' interest will be payable on (or, in the case of an Accrual Class, added to the principal amount of) thatClass even though interest began to accrue approximately 45 or 55 days earlier and (ii) on each subsequentPayment Date (except for certain Callable Classes, in the case of a redemption of the related Callable Asset)the interest payable will accrue during the related Accrual Period, which will end approximately 15 or 25 daysearlier. In the event of a redemption of a Callable Asset, interest payable on certain of the related CallableClasses will include interest to the date of redemption, as described under ""General Information Ì Structureof Transaction Ì The Callable Assets'' in this Supplement.

Yield Tables

The following tables show the pre-tax yields to maturity (corporate bond equivalent) of the Interest Only,Principal Only and Inverse Floating Rate Classes (i) at various constant percentages of PSA, (ii) in the caseof a Callable Class, assuming either that no redemption of the related Callable Asset occurs or that aredemption occurs on one of the Payment Dates shown and (iii) in the case of the Inverse Floating RateClasses, at various constant levels of the applicable Index. The tables for the Interest Only Classes also showannual and total interest payments on those Classes, assuming, if applicable, that no redemption of the relatedCallable Class occurs. Freddie Mac has prepared these tables using the Modeling Assumptions and theassumed purchase prices shown in the table captions. Where the assumed price is expressed as a dollaramount, it includes accrued interest. Where the assumed price is expressed as a percentage of originalprincipal amount, it excludes accrued interest and Freddie Mac has added accrued interest, if any, incalculating the yields shown. The assumed prices are not necessarily those at which actual sales will occur.

The Mortgages will not prepay at any constant rate until maturity, nor will either Index remain constantat any level. Moreover, the Mortgages have characteristics that diÅer from those of the Modeling Assump-tions. Therefore, the actual pre-tax yield of any Class may diÅer from any of those shown in the table for thatClass, even if purchased at the assumed price shown, and the actual annual and total payments for the InterestOnly Classes may also diÅer from any of those shown in the tables for those Classes.

FINAL PAYMENT DATES

The Final Payment Date for each Class is the latest date by which it will be retired. The assumptionsused in calculating the Final Payment Dates are highly conservative, and the actual retirement of any Classmay occur earlier than its Final Payment Date.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

General

Subject to the assumptions described in ""Certain Federal Income Tax Consequences Ì REMICElection'' in the Multiclass OÅering Circulars, the Upper-Tier REMIC Pool and the three Lower-TierREMIC Pools will each qualify as a REMIC for federal income tax purposes.

The following discussion does not consider the federal income tax consequences to a beneÑcial owner of aCallable Class if such owner also has an interest in the related Call Class of Series C057. Accordingly, such abeneÑcial owner should consult its own tax advisor in determining the federal, state, local and any other taxconsequences of the purchase, ownership, exchange or disposition of the Callable Classes.

The arrangement pursuant to which the MACR Classes are created, sold and administered (the ""MACRPool'') will be classiÑed as a grantor trust under subpart E, part I of subchapter J of the Internal RevenueCode. The interests in the Regular Classes that have been exchanged with Freddie Mac for the MACRClasses (including any exchanges eÅective on the Closing Date) will be the assets of the MACR Pool and theMACR Classes will represent beneÑcial ownership of these assets.

Regular Classes

The Regular Classes will be the ""regular interests'' in the Upper-Tier REMIC Pool. The Regular Classeswill be treated as debt instruments for federal income tax purposes and may be issued with original issuediscount (""OID'') or at a premium. Based in part on the level of LIBOR as of the date of this Supplementand assumptions regarding the initial prices at which substantial portions of the Regular Classes will be sold tothe public, Freddie Mac expects to report income to the Internal Revenue Service and to Holders of theRegular Classes assuming they are issued as follows:

‚ OID: EA, EB, EC, ED, FM, K, L, LA, PF, PG, PI, PJ, PQ, PR, PS, PX, PY, S, SA, SB, SC,SD, SE, SG, SH, SJ, SK, SL, SM, SN, SO, SR, ST, SU, SW, W, Z, ZD, ZE, ZF andZG Classes.

‚ De Minimis OID: E, FD, FG, FP, G, GA, GB, GC, H, HA, HB, HC, HH, O, PB, PC, PH, PM,PW, QA, QB, QC, QD, QQ, T, TA, TB, TC, UU and Y Classes.

‚ Premium: A, AP, C, D, FA, FB, FH, J, N, NB, PA, PD, PE, PK, PL, PN, PT, PU, PV, SF, SP,SQ, U and V Classes.

OID generally will result in recognition of taxable income in advance of the receipt of cash attributable tosuch income. The ""Prepayment Assumption'' used in determining whether OID is de minimis and incomputing the rate of accrual of OID or the amortization of premium is 200% PSA for the Group 1 andGroup 7 Classes, 125% PSA for the Group 2 and Group 12 Classes, 130% PSA for the Group 3 Classes, 150%PSA for the Group 4, Group 8, Group 11 and Group 13 Classes, 120% PSA for the Group 5 and Group 14Classes, 197% PSA for the Group 6 Classes, 170% PSA for the Group 9 Classes and 152% PSA for theGroup 10 and Group 15 Classes. See ""Certain Federal Income Tax Consequences Ì Taxation of RegularClasses Ì Original Issue Discount'' and ""Ì Premium'' in the Multiclass OÅering Circulars. Section1272(a)(6) of the Internal Revenue Code, however, authorizes regulations regarding the ""prepayment

S-88

assumption'' to be used in making these determinations. If such regulations are issued, they may require that abeneÑcial owner of a Callable Class take into account, in making these determinations, the possibility of theretirement of such Callable Class concurrently with the redemption of the related Callable Asset.

Freddie Mac intends to report any original issue or market discount or premium with respect to theFloating Rate Classes assuming that each variable rate is a Ñxed rate equal to the value of the variable rate asof the date of this Supplement. See ""Certain Federal Income Tax Consequences Ì Taxation of RegularClasses Ì Floating Rate and Inverse Floating Rate Classes'' in the Multiclass OÅering Circulars.

Residual Classes

The R Class will be the ""residual interest'' in the Upper-Tier REMIC Pool and the RA, RB andRC Classes will each be the ""residual interest'' in a Lower-Tier REMIC Pool. Special tax considerationsapply to the Residual Classes. The taxation of the Residual Classes can produce a signiÑcantly less favorableafter-tax return than if (i) the Residual Classes were taxable as debt instruments or (ii) no portion of thetaxable income on the Residual Classes were treated as ""excess inclusions.'' In certain periods, taxable incomeand the resulting tax liability on the R Class may exceed any payments on that Class. See ""Certain FederalIncome Tax Consequences Ì Taxation of Residual Classes'' in the Multiclass OÅering Circulars. In addition,a substantial tax may be imposed on certain transferors of a Residual Class and certain beneÑcial owners ofsuch a Class that are ""pass-through entities.'' See ""Certain Federal Income Tax Consequences Ì Transfers ofInterests in a Residual Class Ì DisqualiÑed Organizations'' in the Multiclass OÅering Circulars. Investorsshould not purchase a Residual Class before consulting their tax advisors.

Freddie Mac intends to report accruals of original issue discount and market discount and to amortizepremium with respect to the Multiclass Assets using the applicable Prepayment Assumptions set forth aboverather than the prepayment assumptions used in their respective Series.

Certain Transfers of Residual Classes

The REMIC Regulations (as deÑned under ""Certain Federal Income Tax Consequences Ì Transfers ofInterests in a Residual Class Ì Additional Transfer Restrictions'' in the Multiclass OÅering Circulars)disregard:

‚ A transfer of a ""noneconomic residual'' unless no signiÑcant purpose of the transfer is to impedethe assessment or collection of tax; and

‚ Except in certain cases, a transfer of a residual interest to a foreign investor or a transfer of aresidual interest from a foreign investor to a U.S. investor (accordingly, the Multiclass Agreementprohibits the transfer of an interest in a Residual Class to or from a foreign investor withoutFreddie Mac's written consent).

In such cases, the transferor would continue to be treated as the owner of the residual interest and thus wouldcontinue to be subject to tax on its allocable portion of the net income of the REMIC. See ""Certain FederalIncome Tax Consequences Ì Transfers of Interests in a Residual Class Ì Additional Transfer Restrictions''in the Multiclass OÅering Circulars.

Residual Classes with Negative Fair Market Values

The federal income tax consequences of any consideration paid to a transferee on a transfer of a ResidualClass are unclear. The REMIC Regulations do not address whether a residual interest could have a negativebasis and a negative issue price. The preamble indicates that the Internal Revenue Service is considering thetax treatment of these types of residual interests. Any transferee receiving consideration should consult its taxadvisors.

Reporting and Administrative Matters

Freddie Mac will furnish Holders of the Residual Classes the information it deems necessary orappropriate to enable them to prepare any reports required under the Internal Revenue Code or applicableTreasury regulations. Freddie Mac does not intend to hold the Residual Classes for its account, and applicable

S-89

law may not permit Freddie Mac to perform tax administrative functions for the REMIC Pools. Accordingly,the Holders of a Residual Class may have certain tax administrative obligations (for which Freddie Mac willact as attorney-in-fact and agent). See ""Certain Federal Income Tax Consequences Ì Reporting andAdministrative Matters'' in the Multiclass OÅering Circulars.

MACR Classes

For a discussion of certain federal income tax consequences applicable to the MACR Classes, see""Certain Federal Income Tax Consequences Ì Taxation of MACR Classes,'' ""Ì Exchanges of MACRClasses and Multiclass PCs'' and ""Ì Taxation of Certain Foreign Investors'' in the Multiclass PC OÅeringCircular and ""Certain Federal Income Tax Consequences Ì Taxation of MACR Classes,'' ""Ì Exchanges ofMACR Classes and Multiclass Securities'' and ""Ì Taxation of Certain Foreign Investors'' in the MulticlassSecurities OÅering Circular.

LEGAL INVESTMENT CONSIDERATIONS

Investors should consult their legal advisors to determine whether and to what extent any Classesconstitute legal investments for such investors. An institution under the jurisdiction of the Comptroller of theCurrency, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation,the OÇce of Thrift Supervision, the National Credit Union Administration, the Department of the Treasuryor any other federal or state agency with similar authority should review any applicable regulations, policystatements and guidelines before purchasing or pledging any Class. See ""Legal Investment Considerations'' inthe Multiclass OÅering Circulars.

ERISA CONSIDERATIONS

Fiduciaries of ERISA plans should review ""ERISA Considerations'' in the Multiclass OÅering Circularsand in the Callable Asset OÅering Circular.

The discussion under ""ERISA Considerations'' in the Callable Asset OÅering Circular regarding theholding by an ERISA plan of a Callable Asset or the related Call Class, and the holding by a ""party ininterest'' of the other such security, would apply equally with respect to the holding of a Callable Class of thisSeries and the related Call Class.

TERMS SHEET

This Terms Sheet contains selected information about this Series. Investors should refer to theremainder of this Supplement for further information.

General

Description

Each Callable Class, together with its related Call Class (the Call Class having the same numericdesignation), will represent the entire interest in a separate Pass-Through Pool that includes the related GiantPC. Each Class is guaranteed by Freddie Mac but is not guaranteed by, and is not a debt or obligation of, theUnited States. See ""General Information'' and ""Payments Ì Guarantees'' in this Supplement.

Investment Objective

Each investor should determine, either alone or in consultation with an investment advisor, whether ornot a CPC satisÑes such investor's speciÑed investment objectives. See ""Prepayment and Yield Analysis ÌGeneral Ì Suitability'' in this Supplement.

Liquidity

The Underwriter intends to make a market for the purchase and sale of the A3 Class and the Call Classesafter their initial issuance, but has no obligation to do so. There is no assurance that such a secondary marketwill develop or, if it develops, that it will continue. See ""Prepayment and Yield Analysis Ì General ÌSuitability'' in this Supplement.

The Underwriter intends to deliver the A1 and A2 Classes to Freddie Mac in connection with theissuance of Series 1987.

Federal Income Taxes

A beneÑcial owner of an interest in a Callable Class will be treated for federal income tax purposes ashaving purchased an undivided interest in the PCs underlying the related Giant PC and as having written acall option on its interest in such PCs. The beneÑcial owner of the related Call Class will be treated for federalincome tax purposes as holding a call option on such PCs. See ""Certain Federal Income Tax Consequences''in this Supplement and in the OÅering Circular.

The Callable Classes

Interest

The Callable Classes will each bear interest at the applicable Class Coupon shown on the cover page ofthis Supplement. See ""Payments Ì Interest'' in this Supplement.

Allocation of Principal

On each Payment Date, Freddie Mac will pay:

‚ the ""A1 Principal Payment Amount'' for that Payment Date to the A1 Class, until retired



See ""Payments Ì Principal'' and ""Prepayment and Yield Analysis'' in this Supplement.

Payment Behavior

The Callable Classes do not have any Ñxed principal payment schedules. The timing of principalpayments may vary considerably based upon a number of factors, including changes in prevailing interestrates. If prevailing interest rates decrease, principal payments on a Callable Class may accelerate, and any

S-93

reinvestment of such payments might be at such lower prevailing interest rates. Moreover, a Callable Class ismore likely to be redeemed if prevailing mortgage interest rates have decreased. Conversely, if prevailinginterest rates increase, principal payments on a Callable Class may slow down, and investors might receive lessprincipal to reinvest at such higher prevailing interest rates. In that case, the market value of such CallableClass is likely to have declined. See ""Prepayment and Yield Analysis'' in this Supplement.

Redemption

The A3 Class, and subject to certain limitations, the A1 and A2 Classes may be redeemed by FreddieMac, at the direction of the Holder of the related Call Class, on any Payment Date beginning on theapplicable Earliest Redemption Date, in the case of the A1 and A2 Classes, or during the A3 Call Period, inthe case of the A3 Class. Upon a redemption, the investors in the redeemed Callable Class will receive theoutstanding principal amount of that Callable Class, plus interest to the date of redemption in the case of theA1 and A2 Classes or for the related Accrual Period in the case of the A3 Class, calculated as described under""Payments Ì Redemption and Exchange'' in this Supplement.

The A3 Class may be redeemed on any Payment Date beginning on its Earliest Redemption Datethrough September 15, 2017 (the ""A3 Call Period'').

After the A3 Call Period has ended, a Holder of the A3 Class may, subject to the satisfaction of certainconditions and upon the payment of an exchange fee, exchange all or part of such Holder's interest in suchClass for a like principal amount of the related Giant PC. The exchange fee will equal 1/32nd of 1% of theoutstanding principal amount of the portion of the A3 Class being exchanged (but not more than $15,000 orless than $5,000). Such an exchange will be permitted only if the original principal amount of such Giant PC,or portion thereof, received in the exchange was at least $1,000.

See ""Payments Ì Redemption and Exchange'' in this Supplement.

The Call Classes

No Payments

The Call Classes will not receive payments of principal or interest.

Redemption Right

The Holder of a Call Class will have the right to direct Freddie Mac to redeem the related Callable Classon any Payment Date beginning on the Earliest Redemption Date for that Class, in the case of the A1 and A2Classes, or during the A3 Call Period, in the case of the A3 Class. However, a redemption of the A1 or A2Class will be permitted only if, as of the date Freddie Mac receives notice from the Holder of the related CallClass of its intention to redeem, the related Giant PC has a market value in excess of its principal amount.

After payment to Freddie Mac of the Call Payment that will be applied to redeem the related CallableClass and an Exchange Fee in an amount equal to 1/32 of 1% of the outstanding principal amount of suchCallable Class (but not less than $7,500), the Holder of the related Call Class will be entitled to receive fromFreddie Mac, in exchange for such Call Class, the underlying Giant PC. See ""Payments Ì Redemption andExchange'' in this Supplement.

Holders

Only one Holder is permitted to hold a Call Class at any time.
