The Plan

The Plan is a deposit account that allows investors to benefit from potential stock market
growth with the comfort of 100% capital security provided that the Plan is held until the Plan Maturity Date.

The return on Guaranteed Capital Account Global Warming 4 will be dependent upon the growth of an Index of Global Warming related Stocks (called Credit Suisse Global Warming Index).  This index is calculated upon the performance of the 40 Global stocks selected by Credit Suisse and are grouped into the 4 following themes:

• Emissions Limitation - Companies which provide solutions for more efficient energy consumption
• Demand Management - Companies which limit CO2 (Carbon Dioxide) production
• Renewable Electricity - Companies involved in electricity generation from renewable sources
• Renewable Fuels - Companies which create bio-fuels or bio-cells

Please see the sections ‘How does the Plan work?’ and ‘You should note that’ below for more details.

How is The Guaranteed Capital Account - Global Warming brought to you?

Keydata Investment Services Limited is the Account Manager of the Plan.

Leeds Building Society (the Society) is the Deposit Taker for the Plan.

When investments in the Plan are deposited with the Society, investors will acquire
membership rights in the Society.

All of the above are authorised and regulated by the Financial Services Authority (the FSA).

How does the Plan work?

If you maintain your investment in the Plan until the Plan Maturity Date your capital is 100% guaranteed and you may receive a gross growth payment on your subscription amount (your Initial Investment), determined as follows:

• The Index Reference Period is divided into 6 annual periods. At the end of each annual period the percentage gain or fall in the Index is calculated.



• The maximum gain or fall in the Index in any annual period is limited to 18%.



• At the end of the Index Reference Period, the annual period gains in the level of the Index are added and the annual period falls in the level of the Index are subtracted (subject to a maximum gain or fall in any annual period of 18%). This gives the overall percentage return, which is the rate of growth paid on your initial investment.

Important dates of The Guaranteed Capital Account - Global Warming

Availability of the Plan is strictly limited and may close early if oversubscribed. The important dates of the Plan are set out in the table below.

What happens following the Plan Maturity Date?

If you hold the Plan until the Plan Maturity Date you will receive:

• 100% repayment of your Initial Investment;
• any applicable growth payment; and
• a Bonus (if applicable).

You will be contacted prior to the Plan Maturity Date to determine what you wish to do with the proceeds of your Account (please see Terms & Conditions for further details).

Taxation

If you invest in the Plan via a Cash ISA and/or a Cash ISA transfer, any payments made to you under the Plan will be free from UK tax.

If you invest in the Plan via a Direct Deposit Account, any payments to you under the Plan
(other than the repayment of capital) will be taxable income in the year that it is paid and will be subject to tax at your marginal rate.

Payments to you subject to income tax will be made net of tax deducted at source at the lower rate (currently 20%). If you are a higher rate tax payer you will have a further 20% liability to HM Revenue and Customs. Basic rate tax payers will have no further liability to tax. If you have provided a valid declaration on either of HM Revenue and Customs forms R85 or R105 you will receive the full amount of any such payment without deduction of tax.

For companies and charities interest may be paid gross without the deduction of tax. For a
description of the tax treatment of bare trust applications please see the relevant application form.

Direct Deposits in the Plan may be:

• made and held in a bare trust on behalf of another person; and
• made by companies (public or private) and charities.

Please contact the Society or your professional adviser for further information.
For further details, please see ‘Taxation’ and ‘Risk Factors’ in the Key Features.

The meaning of ‘Guarantee’ or ‘Guaranteed’

The use of the word Guarantee and/or Guaranteed refers to the contractual obligations of the Society as Deposit Taker to repay the capital invested by way of a deposit shortly after the Plan Maturity Date.

Investors in the Plan should note that there is no guarantee provided by a third party in the event that the Deposit Taker defaults in respect of its obligations under the Plan.

You should note that:

• The level of the Index may go down as well as up and there can be no assurance as to the future performance of the Index. You should consider whether an investment based on the performance of the Index is suitable for you. Following the Plan Maturity Date, if there is no Index Growth the Plan will repay only your capital.
  
  
• In order to smooth out any fluctuations in the level of the Index at the Plan Maturity Date, the performance of the Index is determined by reference to the average of the closing levels of the Index on each of the 13 monthly Index Averaging Dates in the final year of the Index Reference Period. This means that if the Index falls significantly just before the Plan Maturity Date your potential growth payment is likely to be less severely affected. This will also mean that any rises in the Index during the final year will be averaged, which is likely to reduce your potential growth payment.
  
  
• The performance of the Plan cannot be directly compared to the performance of a direct investment in the Index or the securities comprising the Index as there is no direct investment in the Index or the shares comprising the Index. In particular, you will not benefit from any dividends and you will only have the potential to participate in 108% of the increase (if any), subject to averaging, in the Index.
