Regulatory Advisory

TO: All Members and Employees of Members RA-05-07
(supersedes
RA-03-05)

FROM: CME Market Regulation Department

DATE: June 27, 2005

SUBJECT: Personal Cell Phone Usage and Prohibition of Photography on the
Trading Floors

Staff of the Market Regulation Department has recently received several inquiries
concerning allowable uses of personal cell phones on the trading floors. At its recent
meeting, the Trading Floor Operations Committee reviewed the matter and directed that
this advisory be distributed to clarify the policy to all members and their employees.

The use of personal cell phones by members or their employees on the trading floor to
accept or place orders remains strictly prohibited. However, members may place orders
using their personal cell phones from the member break rooms on the trading floors
provided that the party they are contacting is receiving the order via a CME approved
telecommunication device and not a personal cell phone. CME provides various
approved communication methods for members on the trading floor who wish to accept
or place orders (either directly or through one of their employees) including wired and
wireless headsets or order placement through clearing firm desks or CME Globex
execution operations. Please be reminded that wired and wireless phones issued by
CME may be used only for the purposes for which they have been authorized.

Use of personal cell phones for non-business purposes is permissible anywhere on the
trading floor. Please be advised, however, that use of personal cell phones in a trading
pit for non-business purposes that disrupts or interferes with the orderly operation of the
pit is strictly prohibited.

Additionally, please be reminded that the use of cameras or video equipment is
expressly prohibited on the trading floors without approval by the CME Corporate
Communications Department. This prohibition includes, but is not limited to, the use of
camera or video functionality within cell phones or other telecommunication devices.
