Not clear. We have lines, that have SEV in them, lines with SEV and ATOM, others with those two and COUNT, and many not having any of those. On top, the Guessing wildly, I infer that in a shell loop you want to assign those three values to three variables, but only from lines that have all three in them? Try this:
Code:
sed -nr 's/COUNT=([^;]*).*ATOM=([^;]*).*SEV=([^;]*).*/\1 \2 \3/p' file | while read A B C; do echo $C $B $A; done
Critical KLZCPU.CPUID 3
Warning KLZCPU.CPUID 3
Critical LNXPROC.CMD 3
Critical LNXPROC.PID 4
Critical KLZNET.FIPADDR 3

This depends on the three values to occur in the same sequence in all lines. If that's not the case, you'd need to use e.g. awk.

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
