If by "environment" you mean the exported environment variables.. `exec' 
"retains" them, they will be accessible:

export EXPORTED=foo; non_exported=bar; exec bash -c 'echo "$EXPORTED 
$non_exported"'

-> foo

(perhaps run the above after having run an additional copy of bash if 
your terminal program, say gnome-terminal, closes the window when the 
shell exits, as the exec'd bash will exit immediately after echo'ing).

Or, what you mean by "environment"?
