The date for Oshkosh Truck Corporation's  Annual Meeting was printed incorrectly
on all proxy cards as Monday, February 3, 1999.

in the Proxy Statement.

Your proxy card(s) that were enclosed with your proxy statement are valid for
the Annual Meeting to be held on Monday, February 1, 1999, and should be used
for the appointment of proxies.  You do not need to modify the proxy card(s) to
correct the printing error (although you are free to do so).

We apologize for this error and any inconvenience it may have caused.
