Expect script issue

HI Al,
I have written the following expect script:

Code:

#!/bin/ksh
#!/usr/local/bin/expect--
##echo "PLease enter the server name"
##read host
echo "please enter the instance"
read instance
set ##password to be entered right before the script is run##
##/usr/local/bin/expect<<-EOF
cat serverlist.txt | while {read host};
do
/usr/local/bin/expect<<-EOF
spawn ssh -p 2222 $instance@$host
sleep 1
expect "*Password:*"
sleep 1
send "$1\r"
expect "*/export/home/a61359>#*"
send "/usr/local/bin/top -d 2 >> tempfile.txt\r"
expect "*/export/home/a61359>#*"
send "uuencode tempfile.txt tempfile.txt | mailx -s '$host' myemail@mycompany.com\r"
sleep 1
expect "*/export/home/a61359>#*"
sleep 1
send "rm tempfile.txt\r"
sleep 1
expect "*/export/home/a61359>#*"
sleep 1
send "exit\r"
expect eof
done

This script gives me the error

Code:

./ssh.sh[9]: syntax error at line 11 : `<<' unmatched

when I run it. serverlist.txt is a list of servers in teh same directory as the script
How ever when I run the script by commenting out the while loop and taking the server and the instance name from the user it works.
I have already checked the spaces around the /usr/local/bin/expect<<-EOF and the issue persists.
few noteworthy things.
I have not been able to run expect without having the "/usr/local/bin/expect<<EOF" option.
Could somebody please suggest if I am making a syntax error in the while loop or anything else...
Thanks in advance

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
