As you may know, CME Group reinstated the legacy site, cbot.com, while we worked internally to finalize content and improve select market data behaviors. We paid close attention to the feedback about how cmegroup.com could better meet the needs of our users. In response to that feedback, CME Group has taken measures to improve the following:

• A new section of delayed quotes for all products displayed by asset class
• Time and Sales displayed for the full day, expanded from hourly
• Improved chart functionality
• Faster page load time
• Improved functionality for left navigation
• Resolved the issue of data being removed during market halts

We are pleased to announce that these improvements have been completed and we are now ready to move ahead with the cbot.com site decommissioning. The timing for decommissioning cbot.com is mid-July 2009.

As you visit www.cmegroup.com after the cbot.com decommissioning, we want to take a moment to remind you to bookmark the new pages you are redirected to on cmegroup.com to easily find the information upon your return visit.

In addition to the improvements outlined above, we are taking the following additional measures during the cbot.com decommissioning:

• We will include Spreads data for both CBOT and CME products
• To aid users who have pages on cbot.com bookmarked, all CBOT product and quote pages will be redirected to the corresponding page on cmegroup.com (example: Corn Futures Globex quotes page on cbot.com would redirect to the same page on cmegroup.com).

We continue to seek your feedback on cmegroup.com. Please send us comments and suggestions via the link at the top right corner of each web page on cmegroup.com. You can also contact Customer Service at info@cmegroup.com or 800-331-3332.

We appreciate your support as we move to a single Web site providing valuable information on all of our products and services and continue to improve cmegroup.com to meet your needs.
