| It�s time to update our email list and the On-line Systems Participants List for the Systems Liaison web-site. From now on, we will be sending you this notice and attached Firm Contact Form every two months to ensure that our information is current. Would you please take a moment to complete the attached two-part form so we can update our information as soon as possible? Please note that the information we request regarding "Back Office Manager" and "Back Office Manager's Back-up" is very important. If we need to inform your firm of critical information, it is extremely important that we are able to reach the correct person quickly. You can either FAX the Firm Contact Form to Systems Liaison at (312) 930-8158, or email your form to jperun@cme.com by Thursday, August 31, 2000. Please call Jackie Perun, Information Specialist, at (312) 930-3421 if you have any questions. Thank you for your continued cooperation!
