Sure you know what you are doing?
You are giving probably various linefeeds to your substitution (assuming 
file2 has more than one line).
E.G. 'awk <...> file2' produces as many lines as there are in file2. But 
the substitution in sed has to be a string-like expression with no line 
feeds.

There for the "unterminated substitution" error.
