Voting Rights and Capital

17 May 2010

Pursuant to provisions of the Transparency (Directive 2004/109/EC) Regulations 2007, Allied Irish Banks, p.l.c. ("the Company") declares the following:

The Company's Issued Ordinary Share Capital consists of 1,116,525,417 Ordinary Shares of €0.32. This includes, as at close of business on 13 May 2010, 35,680,114 Ordinary Shares held as Treasury Shares. Therefore, the total number of Ordinary Shares with voting rights relevant to notifying an interest in, or a change to an interest in, the Company is 1,080,845,303.

The Company has in issue 3,500,000,000 Preference Shares of €0.01 each ("the 2009 Preference Shares") with certain voting rights exercisable in certain circumstances; the 2009 Preference Shares carry voting rights in respect of resolutions at a general meeting of the Company for the appointment, re-appointment, or removal of directors and certain matters relating to a proposed change of control of the Company or a sale of all or substantially all of its business. In each case, the voting rights attaching to the 2009 Preference Shares are equivalent to 25% of all votes capable of being cast by shareholders on a poll at a general meeting of the Company. The voting rights with respect to the 2009 Preference Shares are set out in detail in the Company's Articles of Association.

The Company has in issue warrants which entitle the holder to subscribe for 294,251,819 Ordinary Shares, exercisable between the fifth and tenth anniversary of the date of issue of the 2009 Preference Shares on 13 May, 2009. Ordinary Shares issued pursuant to the exercise of these warrants would entitle a Government Preference Shareholder (currently the National Pensions Reserve Fund Commission) to exercise no more than 50 per cent. of the voting rights attaching to such Ordinary Shares, although this restriction does not apply to a holder of such Ordinary Shares that is not a Government entity. The voting rights with respect to the warrants are set out in detail in the Company's Articles of Association.
