--(BUSINESS WIRE)

What: Live demonstrations of the latest in race timing technology,
      presented by Nextel Communications and ChampionChip. See the
      system in action as runners, wearing a small transponder chip
      affixed to their shoes, run over the mats that will be set up at
      strategic locations along the Marathon race route. After
      crossing the mat, a device records the runner and registers
      his/her time, then instantly transmits the information via a
      Nextel wireless phone. On race day, this information will be
      transmitted to timing trailers located at the finish line,
      where the information will be formatted and posted to the
      official Marathon web site, www.chicagomarathon.com.

When: Friday, October 5 at 1:30 p.m. and Saturday,
      October 6 at 2:30 p.m.

When: Saturday, October 6 from 1:00 p.m. to 2:00 p.m.

Where: Both activities will take place at The LaSalle Bank Health and
       Fitness Expo - McCormick Place North.
