Exercise prices divisible by 25 without remainder within a range of 250 index points will be added.  This amendment will be effective for existing contracts including those to be listed in the future beginning with the March 2006 contract following the September 2005 expiration. Amended rules follow with additions underlined and deletions bracketed and struck out.
