As it is already known by a relevant announcement of the ATHEX published on December 23rd, 2002 and according to the rule of the average daily price spread per session (session spread), it is announced that:

1. The shares with a spread less than two (2) percentage units, which is the annual limit set for 2003, will have a continuous five (5) hour trading, i.e. from 11:00 am to 16:00 pm, while

2. The shares with a session spread greater than two (2) percentage units, will have a continuous three (3) hour trading in two periods, i.e. from 11:00am to 11:30am and from 13:30pm to 16:00pm. Between these two periods, buying and selling orders will be entered into the system in order to determine the start price per share upon the starting of the second period (pre-opening procedure).

It should be noted that:

1. The first evaluation will take place on the first session of the ATHEX Board of Directors in May 2003, while the incorporation into the trading hours will take place on June 2, 2003. The period from 2-1-2003 until 30-4-2003 will be the period for the first evaluation of the shares, whereas the period from 1-5-2003 until 30-9-2003 will be the period for the second evaluation. The shares for which the ATHEX Board of Directors approves the initiation of their market making in the transitional stage of May 2003, will be included in the five hour continuous trading regardless of the spread of the session.

2. Shares that will already trade in the three hour continuous trading, will be transferred to the five hour continuous trading provided that a market making agreement is concluded in accordance with the relevant decisions of the ATHEX and the Capital Market Commission (CMC), in spite of their average daily spread. In such cases, the date that the share will be included in the long trading hour session, will be the date that, in accordance with the relevant decision of the ATHEX Board, market making on the share will start.

Finally, it is reminded that the shares that will be traded in the five-hour continuous trading, will be included in the Composite Index of the Main & Parallel Market of the ATHEX, in sector indices and in the FTSE/ASE indices.
