Create a 301 redirect excluding a subdirectory

Create a 301 redirect excluding a subdirectory

I need to do a 301 directory redirect in my httpd.conf file but exclude a
subdirectory within the directory. Example: RedirectPermanent /redirect/
http://www.mysite.com/
But I want to exclude this subdirectory /redirect/example/
Any ideas?
Thanks in advance for you help!
