Page 5 October 2008 Clearstreams existing processing environment Previous settlement engine was designed and deployed to achieve scale and optimisation Quality was evidenced in its night time efficiency, processing over 90% of the volume The old 15 batch daytime deployment leveraged our competence in optimisation Whilst delivering optimal efficiency, it reached its limits to meet evolving customer requirements Queuing times for feedback of internal, bridge and external settlement Suboptimal deadlines

Page 6 October 2008 The solution: proven settlement infrastructure with strong optimisation functionalities… The full set of settlement optimisation functionality is working in real-time from 04:30 to 18:00 CET Securities and cash nettingOptimises settlement efficiency and throughput Self-collateralisation on stock and flow Assists in the funding of own purchase Money Purchase Lien Supports higher trading velocity with less collateralised credit Fails lending Maximises settlement efficiency and reduces the risk of fails Sequencing Enables you to prioritise and control your settlement Provisioning Minimises domestic market turnaround times while recognising a collateral provision to support other settlement Automated collateral allocation and substitution engine Optimises use of securities as collateral for refinancing activities

Page 16 October 2008 The new Bridge: Changing your perception Daytime Bridge : an effective infrastructure for secondary market settlement Settlement efficiency rates over bridge are now equal to internal transactions Quality of ICSD settlement engines and number of instructions exchanges ensures that the most complex chains of transactions are always resolved To ensure that the Bridge is sufficiently robust to support evolving market needs, we need to maintain the pace of progress Joint effort with Euroclear to make continuous improvements to the infrastructure so we eliminate all bottlenecks Push for full interoperability Interoperability Future aim to maximise same-day financing and settlement possibilities and to introduce interoperability between the triparty repo systems of the ICSDs
