These transaction costs will increase the losses or reduce or eliminate the profits referred to in the following examples.

You may draw a limited recourse Loan from UBS by mortgaging Approved Securities and/or Options to UBS.

Unless agreed otherwise with UBS, Interest is prepaid for each Interest Period and is funded by a drawdown under the Loan. The following examples assume that this is the Interest payment arrangement.

1) Drawing down a limited recourse Loan without an Option

You can draw the Loan against Approved Securities that you own to monetise the value of those Approved Securities without an immediate disposal, or you can draw the Loan to purchase new Approved Securities and reduce the amount of capital that you have to contribute yourself. In both cases, you have to mortgage the Approved Securities to UBS as security for the Loan. Due to the limited recourse feature (your Underlying Securities can be applied by UBS at Maturity to satisfy your obligation to repay the Loan Balance), you are effectively protected against a fall in the value of your Underlying Securities below the Facility Amount at Maturity.

For example, say you own 100,000 Underlying Securities, and their current Market Price is $40. You want to borrow 90% of the Market Price of the Underlying Securities, or up to $36 per Underlying Security (90% x

$40), for 2 years from 1 August 2007. This will allow you to borrow $3,600,000 in total – this is the Facility Amount.

Assume Interest is charged at 10% p.a. on each Drawdown Amount. To calculate the amount of cash that you can extract today (the current Available Amount), based on the Facility Amount agreed with UBS, you need to first determine the Interest Amounts. Assume the 2 year Loan is made up of two Interest Periods of one year each. The following Interest Amounts and Interest payment schedule will apply:

Facility Amount: $3,600,000

Cashflows on First Drawdown Date (start of first Interest Period)

Initial Drawdown Amount: $3,240,000

First Interest Amount: $324,000 (10% on initial Drawdown Amount, paid on Drawdown Date)

Net cash made available to you (the current

Available Amount): $2,916,000 (being initial Drawdown Amount less first Interest Amount)

Cashflows at start of second Interest Period

Loan Balance at start of Interest Period: $3,240,000

Additional Drawdown Amount: $360,000 (= second Interest Amount)

New Loan Balance: $3,600,000

Second Interest Amount: $360,000 (10% on current Loan Balance of $3,600,000)

Net cash payment to or by you: nil

At Maturity:

Outstanding Loan Balance: $3,600,000

Loan repayment: $3,600,000 (paid out of your own funds or by UBS exercising its right

At Maturity, depending on the Market Price of the Underlying Securities, there are a number of actions you can take.

a) If the Market Price at Maturity is less than or equal to $36;

You can repay the Loan or do nothing, in which case UBS will sell the Underlying Securities as Mortgagee and apply the proceeds to repay the Loan Balance, without further recourse to you.

b) If the Market Price at Maturity is above $36;

You can instruct UBS to sell your Underlying Securities and apply the proceeds to repay the Loan, and UBS will pay to you any surplus funds (less any costs and Taxes).

For example, if the Underlying Securities are sold at $40, then you will receive, after repayment of the Loan,

$4 per Underlying Security or $400,000 on the total holding of 100,000 Underlying Securities (assuming no other costs or Taxes).

Alternatively you may repay the Loan to UBS using other funds, and UBS will arrange for the Nominee to transfer the Underlying Securities back to you.

2) Drawing down a Loan against Underlying Securities and a Put or a Collar

If you have Put Options or Collars with UBS, you can use the Loan Facility to draw funds against that Option Transaction. You can also use the Loan Facility to purchase Underlying Securities to cover those Options.

For example, assume you have 100,000 Underlying Securities, and their current Market Price is $40. Say, you have also put in place 100,000 “zero-cost” Collars over those Underlying Securities maturing in 2 years time, with a First Premium Amount of zero, a Strike Price of $36, a CPL of $44 and Participation Rate of 0% above the CPL.

If UBS allows you to borrow up to 100% of the Strike Price, then you may borrow up to $36 per Underlying Security for 2 years. Your Facility Amount is therefore $3,600,000.

Assuming an Interest Rate of 10% p.a. and the Loan term being made up of two Interest Periods of one year each, the Interest Amounts and current Available Amount will be as follows:

Facility Amount: $3,600,000

Cashflows on First Drawdown Date (start of first Interest Period)

Initial Drawdown Amount: $3,240,000

First Interest Amount: $324,000 (10% on initial Drawdown Amount, paid on Drawdown Date)

Net cash made available to you (the current

Available Amount): $2,916,000 (being initial Drawdown Amount less first Interest Amount)

Cashflows at start of second Interest Period

Loan Balance at start of Interest Period: $3,240,000

Additional Drawdown Amount: $360,000 (= second Interest Amount)

New Loan Balance: $3,600,000

Second Interest Amount: $360,000 (10% on current Loan Balance of $3,600,000)

Net cash payment to or by you: nil

At Maturity:

Outstanding Loan Balance: $3,600,000

Loan repayment: $3,600,000 (paid out of your own funds, or by UBS exercising its right as mortgagee to sell the Mortgaged Property, including your Underlying Securities, or by set off following the exercise of your Collar)

At Maturity, depending on the Market Price of the Underlying Securities, there are a number of actions you can take.

a) If the Market Price at Maturity is less than or equal to $36;

Assuming that the Collars are exercised, your Underlying Securities will be sold to UBS for $36 per Underlying Security and that amount will be applied to repay your Loan Balance at Maturity.

b) If the Market Price at Maturity is above $36 but below $44;

In this case the Collars will expire worthless.

You can instruct UBS to sell your Underlying Securities, apply the proceeds to repay the Loan, and UBS will pay to you any surplus funds (less any costs and Taxes).

For example, if the Underlying Securities are sold at $40, then you will receive, after repayment of the Loan,

$4 per Underlying Security or $400,000 on the total holding of 100,000 Underlying Securities (assuming no other costs or Taxes). This is the difference between the sale price ($40) and the Loan Balance per Underlying Security ($36).

c) If the Market Price at Maturity is equal to or above $44;

A Second Premium Amount is payable in respect of the Collars because the Market Price is greater than the CPL of $44.

You can instruct UBS to sell your Underlying Securities, apply the proceeds to repay the Loan and pay the Second Premium Amount, and UBS will pass on to you any surplus funds (less any costs and taxes).

For example, if the Market Price is $46, the Second Premium Amount payable (per Underlying Security) will be ($46 – $44 = $2). If the Underlying Securities are sold to UBS at $46, then that amount will be applied to repay the Loan of $36 per Underlying Security and the Second Premium Amount of $2 per Underlying Security. You will therefore net receive, after repayment of the Loan and payment of the Second Premium Amount, $8 per Underlying Security or $800,000 on the total holding of 100,000 Underlying Securities.

3) Drawing down a Loan against Underlying Securities and a Spread Option

If you have Put Spreads or Put Spread Collars with UBS and you hold the Underlying Securities, you can mortgage the Option Transaction and the Underlying Securities to UBS to obtain a Loan. The Facility Amount will be a percentage of the Gap Value.

For example, say you have 100,000 Underlying Securities, and their current Market Price is $40. Say, you purchase 100,000 2-year Put Spread Collars with a Strike Price of $36, a Lower Contingent Payment Level of

$30, an Upper Contingent Payment level of $44 and Participation Rate of 0% in respect of both CPLs. The Gap Value in this case is 100,000 x ($36 – $30) = $600,000. If UBS allows you to borrow up to 100% of the Gap Value then your Facility Amount will be $600,000, or $6 per Underlying Security.

Assuming an Interest Rate of 10% p.a. and the Loan term being made up of two Interest Periods of one year each, the Interest Amounts will be as follows:

Facility Amount: $600,000

Cashflows on Drawdown Date (start of first Interest Period)

Initial Drawdown Amount: $540,000

Net cash made available to you: $486,000 (being initial Drawdown Amount less first Interest Amount)

Cashflows at start of second Interest Period

Loan Balance at start of Interest Period: $540,000

Additional Drawdown Amount: $60,000 (= second Interest Amount)

New Loan Balance: $600,000

Second Interest Amount: $60,000 (10% on current Loan Balance of $600,000)

Net cash payment to or by you: nil

At Maturity:

Outstanding Loan Balance: $600,000

Loan repayment: $600,000 (paid out of your own funds or by UBS exercising its right as mortgagee to sell the Mortgaged Property, including your Underlying Securities, or by set off following the exercise of your Put Spread Collar)

At Maturity, depending on the Market Price of the Underlying Securities, there are a number of actions you can take.

a) If the Market Price at Maturity is less than $30;

You can exercise the Put Spread Collar to sell your Underlying Securities to UBS for $36 per Underlying Security. At the same time, a Second Premium Amount is payable because the Market Price has fallen below the Lower Contingent Payment Level. For example, if the Market Price at Maturity is $28, a Second Premium Amount of $2 per Underlying Security will be payable. The proceeds of the sale of Underlying Securities will be set off against the Second Premium Amount, such that you will be entitled to receive $34 for each Underlying Security that you deliver to UBS. Of that amount, $6 will be applied to repay the Loan that you have drawn from UBS. You will therefore receive, after repayment of the Loan and payment of the Second Premium Amount, $28 per Underlying Security.

b) If the Market Price at Maturity is above $30 but below $36;

You can exercise the Put Spread to sell your Underlying Securities to UBS for $36 per Underlying Security.

You will not be required to pay a Second Premium Amount because the Market Price has not fallen below the Lower Contingent Payment Level. For example, if the Market Price at Maturity is $34, you can exercise the Option and sell your Underlying Securities to UBS for $36 per Underlying Security. Of that amount, $6 will be applied to repay the Loan that you have drawn from UBS. You will therefore receive, after repayment of the Loan, $30 per Underlying Security.

c) If the Market Price at Maturity is above $36 but below $44;

The Collars will expire worthless. You can instruct UBS to sell your Underlying Securities and apply the proceeds to repay the Loan. Alternatively, UBS can exercise its rights under the Mortgage and sell the Underlying Securities and apply the proceeds to repay the Loan. In either case, UBS will pay to you any surplus funds (less any costs and taxes).

For example, if the Market Price is $40, and the Underlying Securities are sold at $40, UBS will apply $6 from the sale proceeds to repay the Loan and pay you the balance of $34 per Underlying Security.

d) If the Market Price at Maturity is equal to or above $44;

A Second Premium Amount is payable because the Market Price is greater than the Upper Contingent Payment Level of $44.

You can instruct UBS to sell your Underlying Securities, apply the proceeds to repay the Loan and pay the Second Premium Amount. If you do not provide any valid instructions, UBS may exercise its rights under the

Mortgage and sell the Underlying Securities and apply the proceeds to repay the Loan and pay the Second Premium Amount. In either case, UBS will pass on to you any surplus funds (less any costs and taxes).

For example, if the Market Price at Maturity is $46, the Second Premium Amount payable per Option will be ($46 – $44 = $2). If the Underlying Securities are sold to UBS at $46, then that amount will be applied to repay the Loan of $6 per Underlying Security and the Second Premium Amount of $2 per Underlying Security. You will therefore receive, after repayment of the Loan and payment of the Second Premium Amount, $38 per Underlying Security or $3,800,000 on the total holding of 100,000 Underlying Securities.
