THE BIOTECH GROWTH TRUST PLC

NET ASSET VALUE

The estimated un-audited net asset value, calculated in accordance with the
guidelines of the Association of Investment Companies, for The Biotech Growth
Trust PLC at the close of business on 1 July 2014 was 535.06p (ex & cum
income).

The Company holds 1,036,604 shares in treasury. In line with the Company's
published policy any re-sale of treasury shares will only take place at a
premium to the prevailing net asset value per share at the time of issue and
therefore the shares held in treasury do not give rise to a potential dilution
to net asset value per share.
