SMORES OVERVIEW

Barclays Structured Mortgage-Linked Retail Securities (SMORES^SM) offer today’s investor the opportunity to attain an attractive yield while earning a monthly income.

SMORES are senior, unsecured, unsubordinated debt securities issued by Barclays Bank PLC. They are designed to give individual investors enhanced yield with an automatic redemption feature tied to the rate of principal prepayments of a specific reference pool and an optional redemption feature which may be exercised by Barclays at its discretion.

SMORES are NOT mortgage-backed securities. SMORES are debt securities that are backed by Barclays. They are, however, linked to a reference pool of mortgages to determine if and when they will be automatically redeemed by Barclays. Even if the mortgage loans underlying the reference pool default, Barclays will pay investors their principal.

Barclays SMORES provide:

• Monthly income stream

• Variety of maturities

• Weekly posting of rates

• Diversification from Treasury and other corporate debt risk

• The credit quality of Barclays

• Competitive rates

KEY TERMS

• Reference Pool – A pool of mortgages (such as fixed rate, level payment mortgages), guaranteed by Government National Mortgage Association (Ginnie Mae), Federal National Mortgage Association (Fannie Mae), or Federal Home Loan Mortgage Corporation (Freddie Mac).

• Pool Factor – An exact decimal value equal to the total outstanding principal balance of all mortgages in the Reference Pool divided by the total original principal balance of all mortgages in the Reference Pool.

• Prepayment – The early repayment of principal on mortgage loans. Changes in prepayment rates are the primary reason the pool factor would decline faster or slower than expected. The variability of prepayment rates makes it uncertain whether Barclays SMORES would be redeemed prior to legal maturity.

• Threshold Factor Table – Reference table of factors set forth in the Free Writing Prospectus used to determine Automatic Redemption.

AUTOMATIC REDEMPTION

Barclays has the obligation to AUTOMATICALLY redeem the securities based on a threshold test

OPTIONAL REDEMPTION

Barclays has the right to redeem the securities at any time following a gap period after issuance

NO REDEMPTION

If the SMORES are not redeemed, principal repayment will occur on the final maturity date

For Illustrative Purposes Only. Please refer to the offering memorandum for final features and further details.

ABOUT MORTGAGE - BACKED SECURITIES

• The first mortgage pool was issued by Government National Mortgage Association (GNMA) in 1970.

• U.S. residential mortgages outstanding at the end of 2006 totaled $10.2 trillion.

• Of those mortgages, $5.7 trillion were securitized into pools, constituting the largest share (24%) of the U.S. Bond Market.

RISKS

We urge you to read the “Risk Factors” section in the applicable offering documents for a detailed discussion of the risks. The following highlights some, but not all, of the risk considerations:

• Principal Protection only if Held to Maturity or Redemption – If you sell in the secondary market, prior to the stated maturity or redemption by Barclays, you may not receive the full principal amount of your SMORES.

• Risk Related to Principal Payments – As the rate of principal payments on the Reference Pool accelerates (or slows down), the likelihood of automatic redemption increases (or decreases). This will impact the timing of the return and reinvestment rate of your principal. The principal amount of your securities may be returned earlier than otherwise anticipated at a time that it cannot be reinvested in products generating an equivalent or greater yield. The prepayment rate is influenced by a complex array of factors and we cannot predict what the prepayment experience of any Reference Pool will be. We also cannot give any assurance as to the certainty or timing of any redemption.

• Liquidity Risk – The securities will not be listed on any securities exchange. Whereas Barclays intends to make a secondary market, there is no guarantee that a secondary market will develop such that you will have access to enough liquidity to trade or sell your securities easily.
