Intention to conduct intraday share repurchase

On 5 May 2010 it was announced that the Company's shareholders had approved at
the Annual General Meeting held on 4 May 2010 (the "AGM"), a renewal of the
Repurchase Program, authorising Lancashire to make one or more purchases of its
issued Common Shares ("Shares") up to a maximum number of 18,250,306 Shares
(representing approximately 10% of issued Share capital of the Company as at
the date of the notice of the AGM).

Further to the aforementioned announcement, Lancashire today announces that it
intends to purchase a total aggregate consideration of US$20,000,000 of its
Shares by way of an on market intraday buyback which is being conducted by
Numis Securities Limited on behalf of the Company and is being made to its
current institutional shareholders through an accelerated bookbuilding process.
Shares purchased may be held as treasury shares or cancelled.

The maximum price (exclusive of expenses payable by the Company) which may be
paid for a Share shall be the higher of: (i) 5% above the average of the
closing middle market quotations for a Share taken from the London Stock
Exchange Daily Official List for the 5 business days immediately preceding the
day on which the Share is contracted to be purchased; and (ii) the higher of
the price of the last independent trade and the highest current independent bid
for the Shares on the London Stock Exchange at the time of purchase as
stipulated by Article 5(1) of the Commission Regulation (EC) No.2273/2003 of 22
December 2003 implementing the Market Abuse Directive (Directive 2003/6/EC of
the European Parliament and of the Council) as regards exemptions for buy-back
programmes and stabilisation of financial instruments.

Given the low level of liquidity of the Shares on the London Stock Exchange,
the Company's brokers have informed the Financial Services Authority and the
Company hereby announces that it will purchase more than the threshold of 25%
of the average daily volume traded of the Shares over the 20 trading days
preceding the date of purchase ("Volume"), and which is likely to result in
purchases over 50% of the Volume.

A further announcement will be released by no later than 7.30am tomorrow
announcing the results of the intra-day buy-back.
