Reference File # 2784.01
Rule Certification
Dear Ms. Donovan:

Pursuant to Commission Regulation 40.6(a), the Chicago Board of Trade (CBOT®) hereby
submits the following:

- Amendments to Regulation 3204.01 per the attached text (deletions bracketed and
struck through).

The referenced amendments will modify the strike price listing intervals for CBOT Soybean Oil
Options. Regulation 3204.01 currently specifies Soybean Oil Options strike prices for the “first
tier” in integral multiples of one-half cent per pound for strikes less than thirty cents and in
integral multiples of one cent per pound for strikes greater than or equal to thirty cents. In
addition, “second tier” strike prices are specified in integral multiples of one cent per pound for
strikes less than thirty cents and in integral multiples of two cents per pound for strikes greater
than or equal to thirty cents. The revised regulation will specify strike price intervals of one-half
cent per pound for the first tier of strike prices and one cent per pound for the second tier, to be
applicable at all price levels.

This revision is in response to customer demand and is designed to enhance the utility of these
options at soybean oil price levels above thirty cents per pound.

The CBOT intends to implement these amendments no sooner than one day after the
Commission’s receipt of this submission.

There were no opposing views concerning these amendments.

The CBOT certifies that these amendments comply with the Commodity Exchange Act and the
rules thereunder.

Sincerely,

Paul J. Draths
Vice President and Secretary
