11. Additional information:

11.1 The Warrants

The warrants, if exercised in full, would entitle the NPRFC to acquire 294,251,819 ordinary shares of the Bank. The NPRFC shall be entitled to exercise no more than 50 per cent. of the voting rights attaching to any ordinary shares which are issued as a result of the exercise of the warrants.

The number of ordinary shares which are the subject of each warrant is capable of being adjusted where there are changes in the share capital of the Bank.

11.2 2009 Bonus Shares

The 2009 Preference Shares entitle the NPRFC to receive a non-cumulative cash dividend at a fixed rate of 8 per cent. of the subscription price of €3.5 billion, payable annually in arrears at the discretion of the Bank. If a cash dividend is not paid by the Bank, the Bank shall make a bonus issue of ordinary shares in the Bank (the "2009 Bonus Shares") to the NPRFC.

The number of 2009 Bonus Shares that the Bank would be required to issue to the NPRFC in the event of non-payment of a cash dividend, is calculated by reference to the net amount of the unpaid dividend amount divided by:

(a) 100 per cent. of the average daily closing or, in the event of no dealings on any day, guide price of ordinary shares of the Bank on the Irish Stock Exchange over the 30 dealing days immediately preceding the original scheduled dividend declaration date, in the event that the 2009 Bonus Shares are issued on the originally scheduled dividend payment date; or

(b) 95 per cent. of the average daily closing or, in the event of no dealings on any day, guide price of ordinary shares of the Bank on the Irish Stock Exchange over the 30 dealing days immediately preceding the original scheduled dividend declaration date, in the event that that the 2009 Bonus Shares are issued later than the originally scheduled dividend payment date.

The 2009 Bonus Stock will rank pari passu with the ordinary shares of the Bank as to voting, save that all voting rights in connection with Board Resolutions shall be calculated in the manner set out above in paragraph 7.2(a).

The 2009 Bonus Shares will be issued on a date determined by the Bank, provided that the date of issue is not later than the date on which the Bank subsequently redeems or repurchases or pays a dividend on the 2009 Preference Shares or any other class of share capital. If any 2009 Bonus Shares become due, but are not issued to the Bank, the NPRFC will be entitled, at a general meeting of the Bank, to cast up to the number of votes that would have attached to the 2009 Bonus Shares had they been so issued on the relevant dividend payment date.
