The options subject to the order constitute portions of grants made to the reporting person on dates ranging from December 14, 1993 through March 14, 2001. Pursuant to the order, the economic benefits of a total of 133,731 of these options have been transferred as of the date of this report and the economic benefits of the balance of the options will be transferred in specified increments as the options vest at various times through 2008. Because the reporting person lacks beneficial ownership in the options subject to the order, these options are no longer included in the reporting person's Section 16 reports. The option vests in three equal annual installments beginning on March 14, 2002. By: Barbara J. Lucas, Attorney-in-Fact for B. Howe 2003-08-04
