It is critically important to note that failure to participate in the next 3 mandatory Mock Trading sessions and five Ticker Tests listed below may severely impede your ability to successfully complete the migration by January 11, 2008.

THERE ARE NO PLANS TO SEND THIS DATA IN PARALLEL VIA CBOT QVN AND CME MDP AFTER THE MIGRATION DEADLINES!

On January 13, 2008 market data for designated e-cbot products will only be sent to you via CME MDP , per the previously published migration schedule. The remaining e-cbot products will be migrated on Sunday, January 27, 2008, followed by the migration of floor-traded products in February 2008. If for any reason you are not able to take the CBOT products via CME MDP, the only alternative for getting this data will be from another quote vendor that has successfully migrated.

Please take a moment to complete the CBOT Migration Readiness Survey that was due this past Monday, December 10, 2007. Completion of this survey is essential so that we understand your current state of migration readiness and can assist you in any manner you may require.
