At the commencement of trading, the CBOT® will list the following strike prices in 10-Year
Note options:

1.) __ the strike price closest to the previous day's settlement price on the
underlying 10-Year Note futures contract (i.e., the at-the-money strike
price);

2.) the next 5 consecutive higher and the next 5 consecutive lower strike
prices in integral multiples of one-half of one point closest to the ATM
strike price; and

3.) the next 25 consecutive higher and the next 25 consecutive lower strike
prices in integral multiples of one full point closest to the ATM strike
price.

4.) one-half of one point strike prices will always be listed for the nearest
quarterly month and the nearest two serial months. Beginning on June 25,
2007, one-half of one point strikes will be available for the August 2007
serial, September 2007 quarterly, and October 2007 serial 10-Year Note
option listings.

The CBOT will add new strike prices in 10-Year Note options over time to ensure that at least 5
strike prices in half-point intervals and at least 25 strike prices in one-point intervals always exist
above and below the previous day’s settlement price on the underlying 10-Year Note futures
contract. The Exchange will add new strike prices prior to the opening of trading on the
