I would suggest:

  color brightcyan "\<(exec|print)([[:blank:]]|$)"

The word "print" must be followed by whitespace or newline.

Of course, print"something" may be valid syntax, but it is
poor style, and I have no problem not coloring things that
are poor style.  Also, print{3} may be valid syntax, but
your regex would color also the opening brace, and probably
you don't want that.

(Also, a "(" is not special inside square brackets, so
a backslash is not needed.  Or do you mean that "print"
should not be highlighted either when followed by "\"?)
