  Assuming your grep supports the Perl regular expression extensions
(a useful thing to have), that should work.

  Or, if you only have an old grep, but do have Perl, the following should work:

perl -pe '/^\*(?!INDICATOR)/ and print' filename.txt

  Otherwise, I agree with what other suggested, using two grep's in a pipeline.
