Critical System Updates

ITC 2.1 Changes on the Market Data Platform
Effective Sunday, October 14, 2007, CME Group will implement changes to the current ITC 2.1 channel schema for CME Globex data on the Market Data Platform. The following channels will be added to the Market Data Platform to provide more granular and scalable ITC 2.1 format market data:

Channel 200 - CME Globex Equity Futures
Channel 201 - CME Globex Equity Options
Channel 202 - CME Globex Interest Rate Futures
Channel 203 - CME Globex Interest Rate Options

Channel 205 - CME Globex FX Options
Channel 206 - CME Globex Commodity, Industrials and TRKRS Futures
Channel 207 - CME Globex Commodity, Industrials and TRKRS Options

These changes only impact the ITC 2.1 channels; there is no change to RLC-format channels.

The current channels 4, 5 and 6 for CME Globex ITC 2.1 market data will be maintained in parallel with the new channels in production until December 1, 2007.

Channel 4 - CME Globex Futures
Channel 5 - CME Globex Options
Channel 6 - CME Globex Spreads

Please note: these ITC 2.1 channels, 4-6 and 200-207, disseminate Top of Book market data only.

These new channels are currently available for customer testing in the New Release environment, and in Certification on October 16. The channel definitions for New Release are now available at www.cme.com/certsdk.

Introducing Alphanumeric Host Order Numbers (HON)
Effective September 15 in the New Release environment, CME Group introduced alphanumeric Host Order Numbers (HON) in FIX tag 37, OrderID, in all applicable iLink messaging. CME Group will force the following December 2007 futures to an alphanumeric HON in New Release:

NYMEX Crude Oil - CLZ7
E-mini S&P 500 ^® - ESZ7
Eurodollar - GEZ7
Euro FX - 6EZ7

Tag 37 is defined with a String format in the iLink Message Specifications module of the iLink Software Development Kit (SDK), so there is no field type change. Tag 37 is used to uniquely identify orders per contract, per trading session. Currently numeric only, tag 37 will use alphanumeric values to support the growth in trading and messaging volume.

Alphanumeric values for tag 37 will be launched in production October 28.

Please note: customer certification for FIX/FAST is mandatory.

In early Q4 2007, CME Group is scheduled to launch the new FIX/FAST market data format on the CME Globex platform. FIX/FAST is the basis of a new industry standard for market data and improves bandwidth scalability. The new format is based on FIX SM and FAST SM protocols for increased efficiency. FIX provides the core message structure and syntax while the FAST protocol increases optimization.

Customers must complete their migration to FIX/FAST from the legacy RLC format market data by October 17, 2008. After October 17, surcharges will be assessed for each site still receiving RLC format market data.

$2,000 per week in October
$4,000 per week in November
$6,000 per week in December

The legacy RLC format market data will be eliminated no later than the end of December 2008.
