Introduction

On 24 April 2012, the boards of Shell Bidco and Cove announced the terms of the cash offer by Shell Bidco, a wholly owned subsidiary of Royal Dutch Shell plc, for the entire issued and to be issued share capital of Cove (the “Offer”). The offer document (the “Offer Document”), which contains, among other things, the full terms and conditions of the Offer and procedures for acceptance of the Offer, was issued by Shell Bidco on 2 May 2012.

On 28 June 2012, Shell Bidco announced the Offer was extended until 1.00 p.m. (London time) on 11 July 2012.

Capitalised terms used in this announcement have the meanings given to them in the Offer Document.

Level of acceptances

As at 1.00 p.m. (London time) on 11 July 2012, Shell Bidco had received valid acceptances of the Offer in respect of 16,066,696 Cove Shares representing approximately 3.27 per cent. of the existing issued share capital of Cove, which Shell Bidco may count towards the satisfaction of the acceptance condition to the Offer. So far as Shell Bidco is aware, none of these acceptances have been received from persons acting in concert with Shell Bidco. Of these acceptances, acceptances have been received in respect of, in aggregate, 4,684,179 Cove Shares (representing approximately 0.95 per cent. of the existing issued share capital of Cove) which were subject to an irrevocable commitment procured by Shell Bidco.

The Offer, which remains subject to the terms and conditions set out in the Offer Document, is being extended and will remain open for acceptance until the next closing date which will be 1.00 p.m. (London time) on 25 July 2012.
