This is to remind you that the election period for the exchange program is scheduled to expire on Friday, September 8, 2006 at 12:00 midnight, Eastern Time. We currently have no plans to extend the expiration date. If you wish to exchange any of your eligible options, you must complete, sign and date the form of election included in Appendix C of the Offer to Exchange and return it to us so that we receive it before the expiration of the election period. Additional copies of the form of election are available on the Source at http://hr.mc.com/optionexchange.
