LAMPRELL PLC

EXPIRY OF THE OFFER PERIOD - OFFER SUCCESSFUL

Further to the offer document dated 19 May 2011 (the "Offer Document") published by Lamprell plc regarding the recommended voluntary cash offer (the "Offer") for 100 per cent. of the shares of Maritime Industrial Services Co. Ltd. Inc. ("MIS") made by its wholly-owned subsidiary Lamprell Investment Holdings Ltd. (together with Lamprell plc, "Lamprell"), an update on the Offer is detailed below.

The acceptance period for the Offer (the "Offer Period") expired on 29 June 2011 at 17:30 CET.

As at the expiry of the Offer Period, Lamprell had received acceptances for approximately 48,081,827 shares in MIS, amounting in aggregate to 99.76 per cent. of the share capital and voting rights in MIS. Please note that the final number of acceptances under the Offer may be subject to change due to possible corrections. As set out in the Offer Document, Lamprell reserves the right, but shall in no event be obliged, to accept any incorrect or late delivered Acceptance Forms (as defined in the Offer Document), and the right to treat an Acceptance (as defined in the Offer Document) of the Offer as valid, in whole or in part, even though it is not entirely in order or not accompanied by the required evidence of authority or if it is received in places other than as set out in the Offer Document.

The completion of the Offer was subject to a number of conditions, which have all been satisfied. Lamprell has therefore resolved to announce that the Offer will complete, subject to the non-occurrence of certain events as set forth in section 1.6 and 1.10 of the Offer Document. Settlement of the Offer will be completed within two weeks following expiry of the Offer Period.

As set out in the Offer Document, Lamprell intends to make a mandatory unconditional offer for the remaining shares in MIS in due course following settlement of the Offer.
