Material Events

The Company's portfolio manager, Graham Birch, has taken sabbatical leave from
the end of March until the beginning of next year. Graham has managed the
Company since its inception in late 1993 and in his absence Evy Hambro will
assume responsibility. Evy began his career with the firm in 1994 and has since
worked closely with Graham.

Material Transactions

During the period, 556,800 shares were bought back and placed in treasury.

On 27 February 2009, 1,313 warrants to subscribe for new ordinary shares were
exercised at an exercise price of 565p per share. This was the final
opportunity for the remaining warrant holders to exercise their subscription
rights and all unexercised warrants have now lapsed.

On 20 April, BlackRock received notification from Merrill Lynch that an amount
of approximately £2m had been received from HMRC relating to VAT incorrectly
levied on management fees for the period from 2001 to September 2006. This
recovery was reflected in the Company's NAV as released to the market on 20
April 2009.

Additional claims remain outstanding in respect of the recovery of VAT,
including a claim against HMRC for payment of interest, but there is
insufficient certainty relating to the outcomes to accrue further amounts in
the net asset value at this time.

The Board is not aware of any material events or transactions, except as
disclosed herein, occurring between 31 March 2009 and the date of publication
of this interim management statement which would have a material impact on the
financial position of the Company. Latest information is available by typing,

Bloomberg or "8800" on Topic 3 (ICV terminal).
