XETR XETRA SIMULATIONMARKET RESET ON JUNI 20, 2012

In order to provide members with the opportunity to test their
 applications in case of technical problems on the exchange side, the
 following scenarios will be provided in the Xetra 12.0 Simulation
 environment (Xetra Frankfurt) on Wednesday June 20, 2012:

 1. Matching engine crash / failover:

 Wednesday June 20, 2012:  16:00 CEST
 First matching engine crashes in simulation, affected instruments VOW,
 DPW, IFX, BAS, ALV, 63DA, EOAA and RWEA. For ISE members: BIR.

 Wednesday June 20, 2012:  16:30 CEST
 Second matching engine crashes in simulation, affected instruments DBK,
 DAI, CBK, BMWA, DPWA, FMEA and SAPA. For ISE members: DOY.

 After the crash of the respective matching engine, another matching engine
 will take over (failover) the processing of all instruments that were
 served by the crashed matching engine.

 In this scenario non-persistent orders and quotes for the set of
 instruments involved will be removed from the Xetra order book. A Market
 Reset Event will be triggered, whereby only persistent orders are restored
 in the order book.

 2. Host crash / failover:

 Wednesday June 20, 2012: 17:00 CEST

 At 17:00 CEST the simulation host will be shut down. The other host will
 take over.

 In this scenario non-persistent orders and quotes will be removed from the
 Xetra order book. A Market Reset Event will be triggered, whereby only
 persistent orders are restored in the order book.
