Trading Continuity System between OSE and Jasdaq Markets Launched

Tokyo, Japan. October 9, 2007 - Osaka Securities Exchange Co., Ltd. (OSE) and Jasdaq
Securities Exchange, Inc. (Jasdaq) today put the related rules into effect, and commenced operations
of Emergency Trading System. As a result, an unprecedented attempt to establish a trading
continuity system between markets was realized.
As a provider of a securities exchange, which is important social infrastructure, OSE and Jasdaq had
made all the necessary arrangements, from May 2006, to establish a scheme to continue trading on
the other exchange in case one exchange faced a difficult situation to continue trading due to an
emergency situation, such as natural disaster - necessary arrangements include (1) modifications of
the platforms, (2) modifications in the rules, etc., including responses to legal issues, (3) impact
study on Transaction Participants and responses to the issues with them, (4) responses to issues on
reporting and/or statistics, (5) impact study on clearing & settlement and responses to the issues, (6)
impact study on information vendors and responses to the issues with them, and so on. OSE and
Jasdaq published the draft rules in related to the trading continuity system in December 2006 and the
final rules in March 2007. After publication of the rules, OSE and Jasdaq conducted the drills to
test the trading continuity system between markets, and commenced the operations of Emergency
Trading System.
Through the implementation of Emergency Trading System, in case a trading platform of one
exchange halts due to a natural disaster, etc. and it is judged to be difficult to resume the trading
promptly, the trading continuity system will be activated and trading will be resumed on the other
exchange, after due consideration on readiness of securities companies, in principle, from the next
business day.
Since this trading continuity system between markets allows OSE and Jasdaq to have a backup
system between two different platforms, OSE Trading Platform and Jasdaq Platform, in addition to a
hot-standby backup, OSE and Jasdaq will become able to respond to a failure arising from the
program which cannot be addressed by a hot-standby backup.
