Cooper Industries plc Statement Of Intention Not To Make A Firm Offer For Laird

Dublin, Ireland, August 1, 2011 – Further to the announcements by each of Cooper (NYSE: CBE) and Laird on 30 July and the statement by the Panel on Takeovers and Mergers on 27 June 2011, Cooper hereby confirms that it does not intend to make an offer for Laird PLC (“Laird”).

For the purposes of Rule 2.8 of the City Code on Takeovers and Mergers (the “Code”), Cooper reserves the right to make, announce or participate in an offer or possible offer, including a reverse takeover, for Laird and/or to take any other action which would otherwise be restricted under Rule 2.8 of the Code within six months of the date of this announcement:
