Dear Ms. Webb:

Chicago Mercantile Exchange Inc. (“CME” or “Exchange") hereby notifies the Commission that
the Exchange has approved amendments to Rule 588.K. to include new COMEX and NYMEX
products, remove a delisted NYMEX product and specify the no bust range for Commodity Options
contracts at any premium level. The rule changes are attached with the addition underlined and
deletions strikethrough.

The Exchange certifies that this regulatory advisory neither violates nor is inconsistent with any
provision of the Commodity Exchange Act or of the rules and regulations thereunder.
If you have any questions regarding this matter, please call me at (312) 648-5422.

Sincerely,
