The Company announces that it has allotted 2,600,000 new ordinary shares of 1p
each for cash, at a price of 119.25 pence per share, a premium to the Company's
net asset value, under its ordinary share blocklisting facility. The new
ordinary shares will rank pari passu with the existing ordinary shares and
dealings are expected to commence on 26 July 2013.

Following the allotment of these shares, the Company will have the ability to
issue a further 4,048,999 shares under its block listing facility.

In addition, the Company wishes to notify the market (as per DTR 5.6.1R) that,
as a result of the above allotment of ordinary shares, the issued share capital
of the Company will consist of 84,288,500 ordinary shares.  Each ordinary share
carries the right to one vote in relation to all circumstances at general
meetings of the Company.  The Company does not hold any ordinary shares in
Treasury.

The above figure may be used by shareholders as the denominator for the
calculations by which they will determine if they are required to notify their
interest in, or a change to their interest in, the Company under the FCA's
