The Certificates may not be suitable investments for you. You should not purchase Certificates unless you have carefullyconsidered and are able to bear the associated prepayment, interest rate, yield and market risks of investing in them.Certain Risk Considerations on page S-2 highlights some of these risks.

You should purchase Certificates only if you have read and understood this Supplement, the attached Offering Circularand the documents identified under Available Information.

We guarantee principal and interest payments on the Certificates. These payments are not guaranteed by, and are not debtsor obligations of, the United States or any federal agency or instrumentality other than Freddie Mac. The Certificates arenot tax-exempt. Because of applicable securities law exemptions, we have not registered the Certificates with any federalor state securities commission. No securities commission has reviewed this Supplement.

CERTAIN RISK CONSIDERATIONS

Although we guarantee the payments on the Certificates, and so bear the associated credit risk, as aninvestor you will bear the other risks of owning mortgage securities. This section highlights some of theserisks. You should also read Risk Factors and Prepayment, Yield and Suitability Considerations in theOffering Circular for further discussions of these risks.

The Certificates May Not be Suitable Investments for You. The Certificates are complexsecurities. You should not purchase Certificates unless you are able to understand and bear the associatedprepayment, interest rate, yield and market risks.

In particular, the Interest Only, Principal Only, Inverse Floating Rate, Support, Retail and ResidualClasses have special risks and are not suitable for all investors.

Prepayments Can Reduce Your Yield. The yield on your Certificates could be lower than youexpect if:

• You buy your Certificates at a premium over their principal amount and principal paymentsare faster than you expect.

• You buy your Certificates at a discount to their principal amount and principal payments areslower than you expect. This is especially true for the Principal Only Class.

If you buy an Interest Only Class and prepayments are fast, you may not even recover your investment.

LIBOR Levels Can Reduce Your Yield if You Own a Floating Rate or Inverse Floating RateClass. The yield on your Certificates could be lower than you expect if:

• You buy a Floating Rate Class and LIBOR levels are lower than you expect.

• You buy an Inverse Floating Rate Class and LIBOR levels are higher than you expect.

If you buy an Interest Only Inverse Floating Rate Class, you may not even recover your investment ifLIBOR levels are high or prepayments are fast.

Retail Classes Have Special Payment Rules. If you invest in a Retail Class, you will receiveprincipal payments in $1,000 increments called “Retail Class Units,” subject to the priorities andlimitations described in Appendix IV to the Offering Circular. The weighted average lives and yields ofindividual Retail Class Units will vary among different investors.

The Certificates are Subject to Market Risks. You will bear all of the market risks of yourinvestment. The market value of your Certificates will vary over time, primarily in response to changes inprevailing interest rates. If you sell your Certificates when their market value is low, you may experiencesignificant losses. The underwriter named on the front cover (the “Underwriter”) intends to make amarket for the purchase and sale of the Certificates after they are issued, but has no obligation to do so. Asecondary market may not develop. Even if one does develop, it may not be liquid enough to allow you tosell your Certificates easily or at your desired price.

Our Multiclass Certificates Offering Circular dated June 1, 2010 (the “Offering Circular”),attached to this Supplement, defines many of the terms we use in this Supplement.

MACR Classes

On each Payment Date when any outstanding MACR Certificates are entitled to principal payments,we allocate such payments from the applicable REMIC Certificates to those MACR Certificates, asdescribed under MACR Certificates in the Offering Circular.

Retail Classes

CC and TT are Retail Classes. If you own a Retail Class, you will receive principal payments in$1,000 Retail Class Units, as described in Appendix IV to the Offering Circular.

See Prepayment and Yield Analysis — Prepayment and Weighted Average Life Considerations —Retail Classes.

REMIC Status

We will form an Upper-Tier REMIC Pool and a Lower-Tier REMIC Pool for this Series. We willelect to treat each REMIC Pool as a REMIC under the Code. R and RS will be “Residual Classes” andthe other Classes shown on the front cover will be “Regular Classes.” The Residual Classes will besubject to transfer restrictions. See Certain Federal Income Tax Consequences in this Supplement and theOffering Circular.

GENERAL INFORMATION

The Trust Agreement

We will form a trust fund to hold the Assets and to issue the Certificates, each pursuant to theMulticlass Certificates Master Trust Agreement dated June 1, 2010 and a Terms Supplement dated theClosing Date (together, the “Trust Agreement”). We will act as Trustee and Administrator under theTrust Agreement.

You should refer to the Trust Agreement for a complete description of your rights and obligationsand those of Freddie Mac. You will acquire your Certificates subject to the terms and conditions of theTrust Agreement, including the Terms Supplement.

S-10

Form of Certificates

The non-Retail Regular and MACR Classes are issued, held and transferable on the Fed System. TheRetail Classes are issued, held and transferable on the DTC System in $1,000 Retail Class Units. TheResidual Classes are issued and held in certificated form and are transferable at the office of the Registrar.

Only a Fed Participant can be a Holder of a non-Retail Regular or MACR Class. DTC or its nomineeis the Holder of each Retail Class. As an investor in Certificates, you are not necessarily the Holder.

See Description of Certificates — Form, Holders and Payment Procedures in the Offering Circular.

Denominations of Certificates

See Description of Certificates — Form, Holders and Payment Procedures in the Offering Circularfor the minimum denominations of the Classes.

Structure of Transaction

General

This Series is a Double-Tier Series, structured as follows:

REMIC Pool Classes Issued from REMIC Pool REMIC Pool Assets

Upper-Tier All Regular Classes and R All Lower-Tier regular interests andRetail Rounding Account

Lower-Tier RS The Assets

See Description of Certificates — REMIC Pool Structures in the Offering Circular.

The PC Assets

The PC Assets are Gold PCs and/or Gold Giant PCs.

The Multiclass Assets

The Multiclass Assets consist of previously issued Freddie Mac REMIC and MACR Certificates,which represent interests in their underlying PCs.

For additional information about the Multiclass Assets, see the Multiclass Asset Offering Circularsand other related information on our internet website. We have attached the front covers, Terms Sheetsand, if applicable, MACR tables from the Multiclass Asset Offering Circulars as Exhibits to thisSupplement.

There may have been material changes since we prepared the Multiclass Asset Offering Circulars,including changes in prepayment rates, prevailing interest rates and other economic factors. Thesechanges may limit the usefulness of, and be inconsistent with the assumptions used in preparing, theMulticlass Asset Offering Circulars.

The Mortgages

The Mortgages underlying the Assets (the “Mortgages”) are fixed-rate, first lien residentialmortgages and mortgage participations.

For purposes of this Supplement, we have made certain assumptions regarding the Mortgagesunderlying the PC Assets, as shown under Terms Sheet — Mortgage Characteristics. The weighted

S-11

average remaining terms to maturity, weighted average loan ages and weighted average interest rates ofthe Mortgages underlying the Multiclass Assets, as of June 1, 2012, are shown under Terms Sheet —Mortgage Characteristics. However, the actual characteristics of most of the Mortgages differ from thoseassumed or shown, perhaps significantly. This is the case even if the weighted average characteristics ofthe Mortgages are the same as those of mortgages having the characteristics assumed or shown.

We may furnish some or all of the Assets from our own portfolio. Assets from our portfolio, or fromother sources, may emphasize specific Mortgage characteristics, such as loan purpose, source oforigination, geographic distribution or loan size, or specific borrower characteristics, such as creditscore or equity in the property. You can obtain information about the underlying Mortgage characteristicsfor the Assets from our internet website.

PAYMENTS

Payment Dates; Record Dates

We make payments of principal and interest on the Certificates on each Payment Date, beginning inthe month following the Closing Date. A “Payment Date” is the 15th of each month or, if the 15th is not aBusiness Day, the next Business Day.

On each Payment Date, any payment on a Certificate is made to the Holder of record as of the end ofthe preceding calendar month.

On each Payment Date, DTC remits payments on the Retail Classes to those DTC participants thatheld Retail Class Units of record as of the end of the preceding calendar month.

Method of Payment

You will receive payments on your Certificates in the manner described under Description ofCertificates — Form, Holders and Payment Procedures in the Offering Circular.

Categories of Classes

For purposes of principal and interest payments, we have categorized the Classes as shown under“Principal Type” and “Interest Type” on the front cover and Appendix A. Appendix II to the OfferingCircular explains the abbreviations used for categories of Classes.

Interest

We pay 30 days’ interest on each Payment Date to the Holders of each Class on which interest hasaccrued. We calculate each interest payment on the outstanding balance of the Class immediately beforethe Payment Date and on the basis of a 360-day year of twelve 30-day months.

Accrual Period

The “Accrual Period” for each Payment Date is:

• For Fixed Rate and Delay Classes — the preceding calendar month.

• For Floating Rate and Inverse Floating Rate Classes other than Delay Classes — from the15th of the preceding month to the 15th of the month of that Payment Date.

S-12

Fixed Rate Classes


Principal Only Class

The Principal Only Class is shown under Terms Sheet — Interest. It does not bear interest.

Notional Classes

The Notional Classes do not receive principal payments. For calculating interest payments, theNotional Classes have notional principal amounts that will reduce as shown under Terms Sheet —Notional Classes.

Floating Rate and Inverse Floating Rate Classes

The Floating Rate and Inverse Floating Rate Classes bear interest as shown under Terms Sheet —Interest. Their Class Coupons are based on one-month LIBOR.

We determine LIBOR and calculate the Class Coupons for the Floating Rate and Inverse FloatingRate Classes as described in Appendix V to the Offering Circular.

Principal

We pay principal on each Payment Date to the Holders of the Classes on which principal is then due.Holders receive principal payments on a pro rata basis among the Certificates of their Class, subject tospecial allocation procedures for investors in a Retail Class.

Amount of Payments

The principal payments on the Certificates on each Payment Date equal the amount of principalrequired to be paid in the same month on the Assets of each applicable Group (the “Group 1 AssetPrincipal Amount,” the “Group 2 Asset Principal Amount” and so forth).

Allocation of Payments

On each Payment Date, we pay the Asset Principal Amounts for that Payment Date as describedunder Terms Sheet — Principal. Principal allocable to the Classes receiving payments from a particularAsset Group will be allocated only to those Classes and will not be available for Classes receivingpayments from the other Asset Groups.

Retail Classes

Appendix IV to the Offering Circular describes how we make principal payments on the RetailClasses.

Class Factors

General

We make Class Factors available on or about the fifth business day of each month after the ClosingDate. See Description of Certificates — Payments — Class Factors in the Offering Circular.

S-13

Use of Factors

You can calculate principal and interest payments by using the Class Factors.

For example, the reduction in the balance of a Certificate in February will equal its original balancetimes the difference between its January and February Class Factors. (The Class Factor for each RetailClass applies to that Class as a whole, not to individual Retail Class Units, and disregards any rounding ofprincipal payments.) The amount of interest to be paid on a Certificate in February will equal 30 days’interest at its Class Coupon, accrued during the related Accrual Period, on the balance of that Certificatedetermined by its January Class Factor. (The interest payable on each outstanding Retail Class Unit inFebruary will be based on its $1,000 balance, without regard to the January Class Factor.)

Guarantees

We guarantee to each Holder of a Certificate the timely payment of interest at its Class Coupon andthe payment of its principal amount as described in this Supplement. See Description of Certificates —Payments — Guarantees in the Offering Circular.

1% Clean-up Call

We have a 1% Clean-up Call Right. If we exercise this right, all of the Classes then outstanding willbe paid in full and will retire. 3751-CI, 3997-DS and 3997-GP may, and the other Multiclass Assets willnot, become subject to the similar 1% Clean-up Call Rights in their Series. See Description ofCertificates — Payments — 1% Clean-up Call in the Offering Circular.

Residual Proceeds

Upon surrender of their Certificates to the Registrar, the Holders of each Residual Class will receivethe proceeds of any remaining assets of the related REMIC Pool after all required principal and interestpayments on the Classes have been made. Any remaining assets are likely to be insignificant. For R, theywill include the Retail Rounding Account. See Description of Certificates — Payments — ResidualClasses in the Offering Circular.

PREPAYMENT AND YIELD ANALYSIS

General

Mortgage Prepayments

The rates of principal payments on the Assets and the Certificates will depend on the rates ofprincipal payments, including prepayments, on the underlying Mortgages. The Mortgages are subject toprepayment at any time without penalty. Mortgage prepayment rates fluctuate continuously and, in somemarket conditions, substantially. See Prepayment, Yield and Suitability Considerations — Prepaymentsin the Offering Circular for a discussion of Mortgage prepayment considerations and risks.

Yield

As an investor in the Certificates, your yield will depend on:

• Your purchase price.

• The rate of principal payments on the underlying Mortgages.

S-14

• The actual characteristics of the underlying Mortgages.

• If you own a Floating Rate or Inverse Floating Rate Class, the level of LIBOR.

• If you own a Fixed Rate or Delay Class, the delay between its Accrual Period and the relatedPayment Date.

• If you own a Group 6, 7, 8 or 9 Class, the payment characteristics of the related MulticlassAssets in their own Series, as described in the Terms Sheets of the related Multiclass AssetOffering Circulars.

• If you own Retail Class Units, when they retire as a result of the special Retail Class principalpayment rules described in Appendix IV to the Offering Circular.

See Prepayment, Yield and Suitability Considerations — Yields in the Offering Circular for adiscussion of yield considerations and risks.

Suitability

The Certificates may not be suitable investments for you. See Prepayment, Yield and SuitabilityConsiderations — Suitability in the Offering Circular for a discussion of suitability considerations andrisks.

Modeling Assumptions

To prepare the tables in this Supplement, we have made several assumptions. Unless otherwisenoted, each table employs the following assumptions (the “Modeling Assumptions”), among others:

• The Mortgages underlying the PC Assets have the characteristics shown under TermsSheet — Mortgage Characteristics.

• As of June 1, 2012, each Mortgage underlying the Multiclass Assets has a remaining term tomaturity 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, ofall the Mortgages underlying the same PC.

• As of the Closing Date, the Assets have the balances shown under Terms Sheet — The Assets.

• The Multiclass Assets receive payments as described in the Multiclass Asset OfferingCirculars.

• The Classes and Assets always receive payments on the 15th of the month, whether or not aBusiness Day.

• We do not exercise our 1% Clean-up Call Right.

• We do not round Retail Class principal payments to multiples of $1,000.

• Each Class is outstanding from the Closing Date to retirement and no exchanges occur.

The Modeling Assumptions, like any other stated assumptions, are likely to differ from actualexperience in many cases. For example, the Mortgages have characteristics more diverse than thoseassumed, many Payment Dates will occur on a Business Day after the dates assumed and we may exerciseour 1% Clean-up Call Right. Moreover, Mortgage prepayment rates will differ from the percentages of

S-15

PSA shown in the tables. These differences will affect the actual payment behavior, weighted averagelives and yields of the Classes, perhaps significantly.

See Prepayment, Yield and Suitability Considerations — Tabular Information in Supplements in theOffering Circular for descriptions of weighted average life and yield calculations and the PSA prepay-ment model.

Prepayment and Weighted Average Life Considerations

PAC and TAC Classes

Principal payments on the PAC and TAC Classes should be more stable than would be the case ifthey did not receive such payments, to the extent of available principal, in accordance with theirschedules. Moreover, they will have cumulative priorities for future payments if they fall behind theirschedules. Based on the Modeling Assumptions, each of these Classes has a range of constant Mortgageprepayment rates (an “Effective Range”) or a single constant Mortgage prepayment rate (an “EffectiveRate”) at which it would receive scheduled payments. The Effective Range or Rate at any time dependson the actual or assumed characteristics of the underlying Mortgages at that time. Based on the ModelingAssumptions, each PAC or TAC Class would receive scheduled payments until retirement if theunderlying Mortgages were to prepay at any constant percentage of PSA within its initial EffectiveRange, or at its initial Effective Rate, shown in the following table.

The initial Effective Ranges, if calculated using the actual characteristics of the Mortgages, coulddiffer from those shown in the table. Even if the Mortgages were to prepay at a constant rate within theinitial Effective Range shown for any Class, but near the upper or lower end of that Effective Range, thatClass might not receive scheduled payments. Moreover, there may not be any constant prepayment rate,based on the actual characteristics of the Mortgages, at which the TAC Class would receive scheduledpayments.

Non-constant prepayment rates can cause any Class not to receive scheduled payments, even if suchrates remain within its Effective Range, if any, shown above. The Effective Ranges can narrow or “drift”

S-16

upward or downward over time. Under many scenarios the Classes shown in the table, especially theType II PAC and TAC Classes, would not receive scheduled payments.

Other Classes support the principal payment stability of the PAC and TAC Classes, as shown below.When its supporting Classes all retire, any outstanding PAC or TAC Class will become more sensitive toMortgage prepayments and its Effective Range, if any, will no longer exist. If a Type II PAC or TAC Classsupports any other Class at that time, its principal payment behavior will become similar to that of aSupport Class, as described below.

If the underlying Mortgages prepay at rates that are generally below the Effective Range or Rate forany Class, the available principal may be insufficient to produce scheduled payments on that Class and itsweighted average life may extend, perhaps significantly. If the underlying Mortgages prepay at rates thatare generally above the Effective Range or Rate for any Class, its weighted average life may shorten,perhaps significantly. However, the weighted average life of any PAC or TAC Class could extend (orshorten) under some scenarios, including “whipsaw” scenarios, involving Mortgage prepayments at ratesthat, on average, are above (or below) its Effective Range or Rate.

We distribute all available principal monthly on each Payment Date and do not retain it fordistribution on subsequent Payment Dates. As a result, the likelihood that the PAC and TAC Classes willreceive scheduled payments will not benefit from averaging high and low principal payments in differentmonths.

Support Classes

The Support Classes support the principal payment stability of the PAC and TAC Classes asdescribed above. As a result, each Support Class is likely to be much more sensitive to Mortgageprepayments than is any Class it supports. The Support Classes may receive no principal payments forextended periods of time, and their principal payment rates may vary widely from month to month.Relatively fast Mortgage prepayments may significantly shorten, and relatively slow Mortgage prepay-ments may significantly extend, the weighted average lives of the Support Classes.

Sequential Pay Classes

The Sequential Pay Classes receive principal payments from their related Assets in a prescribedsequence.

S-17

Pass-Through Classes

Each Pass-Through Class receives a specified portion of the principal payments made on its relatedAssets. The sensitivity of each Pass-Through Class to prepayments on the underlying Mortgages is thesame as that of its related Assets.

The Multiclass Assets

The Group 6 and 7 Assets include Notional (Sequential Pay) Classes that reduce with their relatedSequential Pay Classes. These Sequential Pay Classes receive principal payments from their relatedAssets in a prescribed sequence with other Classes in their Series.

The Group 6 and 7 Assets also include, and the Group 8 Assets consist of, Notional (PAC) Classesthat reduce with their related PAC Classes. The Group 9 Assets consist of a PAC Class. These PACClasses were structured to receive principal payments in accordance with schedules. Based on theModeling Assumptions for this Series, the Group 6, 7 and 8 Assets, in each case taken as a whole, and theGroup 9 Assets, currently have no Effective Ranges. We cannot predict whether or for how long thesePAC Classes might receive scheduled payments.

See Prepayment and Yield Analysis in the Multiclass Asset Offering Circulars.

MACR Classes

The payment characteristics of the MACR Classes reflect the payment characteristics of theirrelated REMIC Classes.

Retail Classes

Principal payments on each Retail Class will depend on the prepayment rate on the underlyingMortgages. As a result, it is uncertain when principal payments on the Retail Classes will begin, how fastthey will occur and when the Retail Classes will retire. Under some prepayment scenarios, your RetailClass Units could retire on the first Payment Date, especially if you invest in TT. On the other hand, theycould retire as late as the Final Payment Date for your Retail Class.

The amount of principal available for payment on a Retail Class on any given Payment Date will belimited. As a result, if you request a Retail Class principal payment, your request may not be honoreduntil long after you submit it. The likelihood that your request will be honored at any particular time willdepend in part on the number of Retail Class Units owned by Deceased Owners who have a prior right ofpayment and on the number of Retail Class Units owned by other Living Owners who have submittedrequests. On the other hand, the amount of principal available for payment on your Retail Class on anygiven Payment Date could exceed the amount necessary to honor all requests. In that case, you mayreceive principal payments you did not request.

When prevailing interest rates are higher than the Class Coupon of a Retail Class, a greater numberof investors in that Class are likely to request Retail Class principal payments. At the same time, however,Mortgage prepayment rates are likely to decline, reducing the funds available for Retail Class principalpayments. By contrast, Mortgage prepayment rates are likely to accelerate when prevailing interest ratesdecline, while investors may be less likely to request Retail Class principal payments. If your RetailClass Units are selected for payment under such conditions, you may not be able to reinvest yourpayments in comparable securities at as high a yield.

S-18

The following tables show the amounts that would be available for principal payments on the RetailClasses during the twelve-month periods indicated at various percentages of PSA. We have preparedthese tables using the Modeling Assumptions. Because you will receive principal payments on yourRetail Class in multiples of $1,000 and subject to special payment rules, you may not receive a principalpayment on any particular date.

The amounts available for principal payments on a Retail Class during any twelve-month period arelikely to differ in many cases from the amounts shown in the table.

The weighted average lives of each Retail Class shown in the declining balances table below applyto that Class as a whole; the weighted average lives of your Retail Class Units will vary, and may varysignificantly, from the weighted average life of the related Retail Class. We cannot predict the weightedaverage life of a Retail Class as a whole, much less the weighted average life of any particular Retail ClassUnit.

Declining Balances Table

The following table shows:

• Percentages of original balances (as of the Closing Date) that would be outstanding aftereach of the Payment Dates shown at various percentages of PSA.

• Corresponding weighted average lives.

We have prepared this table using the Modeling Assumptions. However, for 0% PSA we haveassumed that each Mortgage underlying the PC Assets has (a) an interest rate 2.5% higher than that of therelated PCs and (b) a remaining term to maturity of 180, 240 or 360 months, as applicable, and a loan ageof 0 months. We have calculated weighted average lives for each Notional Class assuming that areduction in its notional principal amount is a reduction in principal balance.

FINAL PAYMENT DATES

The Final Payment Date for each Class is the latest date by which it will be paid in full and willretire. We calculate Final Payment Dates using highly conservative assumptions. The actual retirement ofeach Class may occur earlier than its Final Payment Date.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

General

Any discussion of tax matters herein and in the Offering Circular was not intended or written to beused, and cannot be used, by any person for the purpose of avoiding tax penalties that may be imposed onsuch person. Such discussion was written to support the promotion and marketing of the Certificates.Investors should consult their own independent tax advisors regarding the Certificates and each investor’sparticular circumstances.

Subject to the assumptions described under Certain Federal Income Tax Consequences — REMICElection in the Offering Circular, the Upper-Tier REMIC Pool and the Lower-Tier REMIC Pool will eachqualify as a REMIC for federal income tax purposes.

Regular Classes

The Regular Classes are “regular interests” in the Upper-Tier REMIC Pool. See General Informa-tion — Structure of Transaction. They are treated as debt instruments for federal income tax purposes andmay be issued with original issue discount (“OID”) or at a premium. Based in part on (a) the level ofLIBOR on the date of this Supplement and (b) information provided by the Underwriter regarding theinitial prices at which it would have expected to sell or will sell substantial portions of the RegularClasses, we expect to report income to the Internal Revenue Service and to Holders of the RegularClasses assuming they are issued as follows:

• OID: AI, AS, BI, CS, GO, HS, IG, IK, LI, SA and SH.

• De Minimis OID: CE, FC, GB, GC, GE, GF, GK, GS, GY and SL.

• Premium: AK, AP, BP, CB, CC, CP, GD, GH, HA, HB, LA, LB, LC, LF, PB, PC and TT.

OID generally results in recognition of taxable income in advance of the receipt of cash attributableto that income. The Pricing Speeds used for OID and premium calculations are:

• Group 1 — 190% PSA

• Groups 2, 6 and 9 — 250% PSA

• Groups 3, 4 and 5 — 200% PSA

• Groups 7 and 8 — 300% PSA

See Certain Federal Income Tax Consequences — Taxation of Regular Classes — Original Issue Dis-count and — Premium in the Offering Circular. Mortgage prepayment rates will differ, perhaps signif-icantly, from the Pricing Speeds shown above.

S-33

Residual Classes

Each Residual Class is the “residual interest” in its related REMIC Pool. See General Informa-tion — Structure of Transaction. Special tax considerations apply to the Residual Classes. The taxation ofthe Residual Classes can produce a significantly less favorable after-tax return than if (a) the ResidualClasses were taxable as debt instruments or (b) no portion of the taxable income on the Residual Classeswere treated as “excess inclusions.” In certain periods, taxable income and the resulting tax liability on aResidual Class may exceed any payments on that Class. See Certain Federal Income Tax Consequen-ces — Taxation of Residual Classes in the Offering Circular.

A substantial tax may be imposed on certain transferors of a Residual Class and certain beneficialowners of a Residual Class that are “pass-through entities.” See Certain Federal Income Tax Con-sequences — Transfers of Interests in a Residual Class — Disqualified Organizations in the OfferingCircular. You should not purchase a Residual Class before consulting your tax advisor.

We intend to report accruals of OID and market discount and to amortize premium with respect tothe Multiclass Assets using the applicable Pricing Speeds shown above, regardless of the Pricing Speedsused in their Series.

Certain Transfers of Residual Classes

The REMIC Regulations disregard:

1. A transfer of a “noneconomic residual interest” unless no significant purpose of the transfer is toimpede the assessment or collection of tax.

2. 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 Trust Agreementprohibits the transfer of an interest in a Residual Class to or from a foreign investor without ourwritten consent.

See Certain Federal Income Tax Consequences — Transfers of Interests in a Residual Class — Addi-tional Transfer Restrictions in the Offering Circular. In the case of a transfer that is disregarded, thetransferor would continue to be treated as the owner of the residual interest and thus would continue to besubject to tax on its allocable portion of the net income of the REMIC.

MACR Classes

The arrangement under which the MACR Classes are created (the “MACR Pool”) will be classifiedas a grantor trust under subpart E, part I of subchapter J of the Code. The interests in the Regular Classesthat have been exchanged for the MACR Classes, including any exchanges effective on the Closing Date,will be the assets of the MACR Pool and the MACR Classes will represent beneficial ownership of theseassets.

For a discussion of certain federal income tax consequences applicable to the MACR Classes, seeCertain Federal Income Tax Consequences — Taxation of MACR Classes, — Exchanges of MACRClasses and Regular Classes and — Taxation of Certain Foreign Investors in the Offering Circular.

ERISA CONSIDERATIONS

Fiduciaries of employee benefit plans should review ERISA Considerations in the Offering Circular.

S-34

ACCOUNTING CONSIDERATIONS

You should consult your accountant for advice on the appropriate accounting treatment for yourCertificates. See Accounting Considerations in the Offering Circular.

LEGAL INVESTMENT CONSIDERATIONS

You should consult your legal advisor to determine whether the Certificates are a legal investmentfor you and whether you can use the Certificates as collateral for borrowings. See Legal InvestmentConsiderations in the Offering Circular.

PLAN OF DISTRIBUTION

Under an agreement with the Underwriter, we have agreed to sell all of the REMIC Certificates tothe Underwriter in exchange for the Assets.

The Underwriter is offering the Certificates to the public in negotiated transactions at varying pricesto be determined at the time of sale, plus accrued interest on each interest-bearing Class from the first dayof its initial Accrual Period. The Underwriter is offering the Certificates subject to their issuance by usand subject to the Underwriter’s right to reject any order. The Underwriter may make sales to or throughsecurities dealers. The dealers may receive compensation in the form of discounts, concessions orcommissions from the Underwriter and commissions from any purchasers for which they act as agents.

The sales commission charged to a retail investor is likely to be a higher percentage of the sales pricethan the commission charged to an institutional investor in any Class.

Our agreement with the Underwriter provides that we will indemnify it against certain liabilities.

LEGAL MATTERS

Our General Counsel or one of our Deputy General Counsels will render an opinion on the legalityof the Certificates. Bingham McCutchen LLP is representing the Underwriter on legal matters con-cerning the Certificates.

TERMS SHEET



Payment Dates

We make payments of principal and interest on the Certificates on each monthly Payment Datebeginning in November 2010.

Form of Classes

Regular, Callable and MACR Classes: Book-entry on Fed System

Residual and Call Classes: Certificated

Callable Pass-Through Certificates

The Callable Class (CP), together with the Call Class (C1), will represent the entire interest in CX(the “Underlying REMIC Class”). The Underlying REMIC Class will be issued on the Closing Date butwill be held by Freddie Mac unless and until the Callable Class is redeemed.

If you are the Holder of the Call Class, you will have a call right (the “Call Right”) as to the CallableClass. See Summary — Call and Callable Classes in the Offering Circular. You must pay a Call Fee and aCall Payment to exercise the Call Right. The Call Right allows you to direct Freddie Mac to redeem theCallable Class on any Payment Date on or after April 15, 2011 (the “Earliest Redemption Date”).

If you exercise the Call Right, you will receive the Underlying REMIC Class. However, you mayexercise your Call Right only if, at the time we receive notice of your intention to exercise, the UnderlyingREMIC Class has a market value (as determined by Freddie Mac, in its sole judgment and discretion) thatequals or exceeds its principal amount.

Appendix C describes the required payments and procedures for exercising the Call Right. Toexercise the Call Right, you must notify Freddie Mac at least five business days before the end of thecalendar month preceding the Redemption Date, in the manner described in Appendix C.

Upon a redemption, the Holders of the Callable Class will receive, on the Redemption Date, theremaining principal balance of their CPCs and 30 days’ interest accrued during the preceding calendarmonth. They will not receive any interest in respect of the month in which the redemption occurs.

The Call Class will not receive payments of principal and interest.

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

Interest


BO (a MACR Class), NO and OH are Principal Only Classes and do not bear interest.

We will form an Upper-Tier REMIC Pool, a Lower-Tier REMIC Pool and a Callable Pass-ThroughPool for this Series. We will elect to treat each REMIC Pool as a REMIC under the Code. R and RS willbe “Residual Classes” and the other Classes shown on the front cover (other than C1 and CP) will be“Regular Classes.” The Residual Classes will be subject to transfer restrictions. The Callable Pass-Through Pool will be treated as a grantor trust under the Code. See Certain Federal Income TaxConsequences in this Supplement and the Offering Circular.

If you own the Callable Class, you will be treated for federal income tax purposes as owning theUnderlying REMIC Class and as having written a call option on the Underlying REMIC Class.

If you own the Call Class, you will be treated for federal income tax purposes as holding a call optionon the Underlying REMIC Class.

TERMS SHEET



Payment Dates

We make payments of principal and interest on the Certificates on each monthly Payment Datebeginning in December 2010.

Form of Classes




Each Callable Class, together with the related Call Class, will represent the entire interest in therelated “Underlying REMIC Class” shown in the following table. Each Underlying REMIC Class willbe issued on the Closing Date but will be held by Freddie Mac unless and until the related Callable Classis redeemed.

Group Callable Class Call Class Underlying REMIC Class

1 CP P1 PX3 CM M1 MX

If you are the Holder of a Call Class, you will have a call right (the “Call Right”) as to the relatedCallable Class. See Summary — Call and Callable Classes in the Offering Circular. You must pay a CallFee and a Call Payment to exercise your Call Right. The Call Right allows you to direct Freddie Mac toredeem the related Callable Class on any Payment Date on or after May 15, 2011 (the “EarliestRedemption Date”).

If you exercise your Call Right, you will receive the related Underlying REMIC Class. However,you may exercise your Call Right only if, at the time we receive notice of your intention to exercise, therelated Underlying REMIC Class has a market value (as determined by Freddie Mac, in its sole judgmentand discretion) that equals or exceeds its principal amount.

Appendix C describes the required payments and procedures for exercising your Call Right. Toexercise your Call Right, you must notify Freddie Mac at least five business days before the end of thecalendar month preceding the Redemption Date, in the manner described in Appendix C.

Upon a redemption, the Holders of a Callable Class will receive, on the Redemption Date, theremaining principal balance of their CPCs and 30 days’ interest accrued during the preceding calendarmonth. They will not receive any interest in respect of the month in which the redemption occurs.

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

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

MACR Classes


REMIC Status

We will form an Upper-Tier REMIC Pool, a Lower-Tier REMIC Pool and two Callable Pass-Through Pools for this Series. We will elect to treat each REMIC Pool as a REMIC under the Code. R andRS will be “Residual Classes” and the other Classes shown on the front cover (other than the Callableand Call Classes) will be “Regular Classes.” The Residual Classes will be subject to transfer restrictions.Each Callable Pass-Through Pool will be treated as a grantor trust under the Code. See Certain FederalIncome Tax Consequences in this Supplement and the Offering Circular.

If you own a Callable Class, you will be treated for federal income tax purposes as owning therelated Underlying REMIC Class and as having written a call option on the related Underlying REMICClass.

If you own a Call Class, you will be treated for federal income tax purposes as holding a call optionon the related Underlying REMIC Class.

* We calculate weighted average lives based on the assumptions described in Prepayment and Yield Analysis and, in the case of theCallable Classes, the various redemption scenarios shown. The actual weighted average lives are likely to differ from thoseshown, perhaps significantly, and any redemption of a Callable Class is likely to occur on a date other than those shown.

MACR Classes


REMIC Status

We will form an Upper-Tier REMIC Pool, a Lower-Tier REMIC Pool and two Callable Pass-Through Pools for this Series. We will elect to treat each REMIC Pool as a REMIC under the Code. R andRS will be “Residual Classes” and the other Classes shown on the front cover (other than the Callableand Call Classes) will be “Regular Classes.” The Residual Classes will be subject to transfer restrictions.Each Callable Pass-Through Pool will be treated as a grantor trust under the Code. See Certain FederalIncome Tax Consequences in this Supplement and the Offering Circular.

If you own a Callable Class, you will be treated for federal income tax purposes as owning therelated Underlying REMIC Class and as having written a call option on the related Underlying REMICClass.

If you own a Call Class, you will be treated for federal income tax purposes as holding a call optionon the related Underlying REMIC Class.

See Terms Sheet — Callable Pass-Through Certificates and General Information — Structure of the

Transaction.



We guarantee principal and interest payments on the Certificates and the proceeds due on the Call Class upon exercise ofthe Call Right. These payments are not guaranteed by, and are not debts or obligations of, the United States or any federalagency or instrumentality other than Freddie Mac. The Certificates are not tax-exempt. Because of applicable securitieslaw exemptions, we have not registered the Certificates with any federal or state securities commission. No securitiescommission has reviewed this Supplement.

TERMS SHEET



Payment Dates

We make payments of principal and interest on the Certificates on each monthly Payment Datebeginning in February 2012.

Form of Classes




The Callable Class (CD), together with the Call Class (C1), will represent the entire interest in CX(the “Underlying REMIC Class”). The Underlying REMIC Class will be issued on the Closing Date butwill be held by Freddie Mac unless and until the Callable Class is redeemed.

If you are the Holder of the Call Class, you will have a call right (the “Call Right”) as to the CallableClass. See Summary — Call and Callable Classes in the Offering Circular. You must pay a Call Fee and aCall Payment to exercise the Call Right. The Call Right allows you to direct Freddie Mac to redeem theCallable Class on any Payment Date on or after July 15, 2012 (the “Earliest Redemption Date”).

If you exercise the Call Right, you will receive the Underlying REMIC Class. However, you mayexercise the Call Right only if, at the time we receive notice of your intention to exercise, the UnderlyingREMIC Class has a market value (as determined by Freddie Mac, in its sole judgment and discretion) thatequals or exceeds its principal amount.

Appendix C describes the required payments and procedures for exercising the Call Right. Toexercise the Call Right, you must notify Freddie Mac at least five business days before the end of thecalendar month preceding the Redemption Date, in the manner described in Appendix C.

Upon a redemption, the Holders of the Callable Class will receive, on the Redemption Date, theremaining principal balance of their CPCs and 30 days’ interest accrued during the preceding calendarmonth. They will not receive any interest in respect of the month in which the redemption occurs.

The Call Class will not receive payments of principal and interest.

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

MACR Classes


REMIC Status

We will form two Upper-Tier REMIC Pools, two Lower-Tier REMIC Pools and a Callable Pass-Through Pool for this Series. We will elect to treat each REMIC Pool as a REMIC under the Code. R, RA,RS and RTwill be “Residual Classes” and the other Classes shown on the front cover (other than CD andC1) will be “Regular Classes.” The Residual Classes will be subject to transfer restrictions. The CallablePass-Through Pool will be treated as a grantor trust under the Code. See Certain Federal Income TaxConsequences in this Supplement and the Offering Circular.

* We calculate weighted average lives based on the assumptions described in Prepayment and Yield Analysis and, in the case of theCallable Class, the various redemption scenarios shown. The actual weighted average lives are likely to differ from those shown,perhaps significantly, and any redemption of the Callable Class is likely to occur on a date other than those shown.

MACR Classes


REMIC Status

We will form two Upper-Tier REMIC Pools, two Lower-Tier REMIC Pools and a Callable Pass-Through Pool for this Series. We will elect to treat each REMIC Pool as a REMIC under the Code. R, RA,RS and RTwill be “Residual Classes” and the other Classes shown on the front cover (other than CD andC1) will be “Regular Classes.” The Residual Classes will be subject to transfer restrictions. The CallablePass-Through Pool will be treated as a grantor trust under the Code. See Certain Federal Income TaxConsequences in this Supplement and the Offering Circular.


If you own the Call Class, you will be treated for federal income tax purposes as holding a call optionon the related REMIC Class.
