STOCK EXCHANGE NOTICE

DOMESTIC EQUITY MARKET
ORDER BOOK - EURO PRICE FORMAT CODES

1. Stock Exchange Notice N30/99 stated that, in order to give market 
participants time to prepare for the new euro tick sizes, the Exchange trading
system would temporarily use the decimal price format code for euro priced
securities on the order book. This format has applied to each of the four
Irish securities which currently trade on the order book in euro. 

2. This Notice informs member firms that, with effect from Monday 20 September
1999, the Exchange trading system will use the price format codes (J, K and L)
which correspond exactly with the new euro tick sizes (1/100, 1/200 and 1/400
euro). The trading system will automatically reject orders (or quotes where
appropriate) which are not submitted in multiples of the relevant tick size
for a security.

3. The price format code for each of the four order book securities currently
trading in euro on the order book will be amended on the trading system to
conform with the existing tick sizes of the securities as follows:

       Company                                    Tick Size (euro)

       Allied Irish Banks PLC                     1/100       (0.01   euro)
       Bank Of Ireland (Governor & Co of)         1/100       (0.01   euro)
       Bord Telecom Eireann PLC                   1/200       (0.005  euro)
       CRH PLC                                    1/100       (0.01   euro)
       
4.  These tick sizes will be reviewed as part of the next scheduled review of
order book tick sizes.
