Search for a string, then append character to end of that line only

I have 2 files that I am working with

Code:
$ cat file1
server1
server3
server5
server6
server8


Code:
$ cat file2
server1;Solaris;
server2; SLES;
server3;Linux;
server4; Solaris;
server5;SLES;
server6;SLES;
server7;Solaris;
server8;Linux;

my script

Code:
#!/bin/ksh
# if there is a match, write "HIT" at EOL
#set -x

while read LINE; do
    line2=`grep "$LINE" file2`
    if [ -n "$line2" ] ; then
#      awk '/$line2/{print $0, "HIT"}' file2  ##>> file4
#      sed "s/$/ HIT/" file2
#      sed '/$line2/s/$/ HIT/' file2
       sed '/server1/s/$/ HIT/' file2
    else
        echo "$line2" ##>> file4
    fi
done < file1

expected output
Code:
server1;Solaris; HIT
server2; SLES;
server3;Linux; HIT
server4; Solaris;
server5;SLES; HIT
server6;SLES; HIT
server7;Solaris;
server8;Linux; HIT

I have been trying both sed and awk but no luck so far.

cat(1)							      General Commands Manual							    cat(1)

Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The  command reads each file in sequence and displays it on the standard output.  Therefore, to display the file on the standard output you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file.  Output is buffered in
       1024-byte blocks unless the standard output is a terminal, in which case it is line buffered.  The utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores blank lines and precedes each output line with its line number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with line numbers.

       -s   Squeezes adjacent blank lines from output and single spaces output.

       -t   Displays non-printing characters (including tabs) in output.  In addition to those representations used with the -v  option,  all  tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays  non-printing  characters (excluding tabs and newline) as the ^x.	If the character is in the range octal 0177 to octal 0241,
	    it is displayed as M-x. The delete character (octal 0177) displays as ^?.  For example, is displayed as ^X.
