How do I pass variables between two servers?

I am taking input from user for a shell script, and want to run this script on different servers.

I tried to pass the variables as follows: 

    USERNAME=****
    HOSTS="**** ***** *****"    
    FOO=$1
    BAR=$2
    for HOSTNAME in ${HOSTS} ; do
        ssh $USERNAME@$HOSTNAME bash << EOF

    #script using FOO and BAR variables goes here

    EOF

Login to the server is successful but variables are not being passed.

How can handle this situation without creating a temp file?
