MOD re-write problem

[3Y3]

On my site I'm using TextPattern and it wants one mod rewrite rule to handle virtual directories (the last line), but there are some folders on my system that I don't want it to touch (mainly .htpasswd'd directories). How do I add a condition to my .htaccess so that it excludes specific folders?

I want to exclude

http://www.example.com/myPasswordedFolder/

<

http://www.example.com/myPasswordedFolder/>

http://www.example.com/myPasswordedFolder2/

<

http://www.example.com/myPasswordedFolder2/>

and their child folders but send anything in

http://www.example.com/random/virtual/folder/

<

http://www.example.com/random/virtual/folder/>

etc...
to index.php

This is the .htaccess as it currently exists:

# DirectoryIndex index.php index.html
Options +FollowSymlinks
RewriteEngine On
RewriteBase /

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+) - [PT,L]

RewriteRule ^(.*) index.php

</IfModule>
