Dear CME Globex Customers,

Effective this Sunday, March 12, 2006 (for trade date Monday, March 13), the order entry quantity caps for CME E-mini Euro FX and CME E-mini Japanese Yen futures contracts will be increased to 50 contracts. The quantity cap for these two products is currently set at 30 contracts each.

The order entry quantity cap limits the number of bids or offers that can be submitted to the CME Globex electronic trading platform in a single order. CME E-mini Euro FX or CME E-mini Japanese Yen futures orders that exceed 50 contracts must be submitted into the CME Globex platform in multiple orders, each of which can not exceed 50 contracts.

For more information on this CME Globex product change, please contact David Schulz, CME Foreign Exchange, at 312.930.3426; or your CME Globex Account Manager at 312.634.8700; or in Europe at +44.201.623.2550.

Thank you,

CME
