Re: Amendments to Rule 21.25 -
Submission Pursuant to Section 5c(c)(1) of the Act and Regulation 40.6

Dear Ms. Webb:

Pursuant to Section 5e(c)(1) of the Commodity Exchange Act, as amended, and
Commission Regulation 40.6, the Board of Trade of the City of New York, Inc. (“Exchange”)
submits, by written certification, amendments to Rule 21.25, attached as Exhibit A.

The amendments to Rule 21.25 will permit the use of certain wireless communication
devices in the Exchange’s trading rings. Currently, Rule 21.25(b)(i)(A)17 prohibits the use of
any type of wireless communication device. But technology has evolved so that floor members
could use a wireless, handheld device that enables the user to receive live market data feeds and
communicate with others by instant-messaging. The amendments, then, will delete the
prohibition from Rule 21.25(b)(i)(A)17 subject to certain conditions as stated below.

The amendments to Rule 21.15(b)(i)(A)8 will require a floor member to receive
certification or authorization by the Exchange’s Department of Technology (“Department”) prior
to using the wireless device. At the present time, the Department will only approve those
devices that receive the live data feeds, enable two-way communication and have audit trail
capability for monitoring. Orders to execute Exchange transactions will not be permitted to be
transmitted on the devices.

The Exchange certifies that the amendments comply with the requirements of the
Commodity Exchange Act and the rules and regulations promulgated thereunder.

The amendments were adopted by the Exchange’s Board of Governors on April 28, 2006.
No substantive opposing views were expressed by members or others with respect to the



amendments. The amendments will become effective on a date set by the President twenty-four
(24) hours after filing with the Commission.
