Redirect most of the subfolders (with exceptions)

Question

I'd like to redirect all subfolders of a language to the language folder, except 2 URLs. For example :

http://example.com/es/folder1/
http://example.com/es/folder1/folder2/
except http://example.com/es/terms-of-use/ and http://example.com/es/privacy-policy/

should redirect to http://example.com/es/

I tried the following without success :

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/es/terms-of-use/
RewriteCond %{REQUEST_URI} !^/es/privacy-policy/
RewriteRule ^/es/(.+)$ www.example.com/es/ [R=301,L]

Do you have any suggestions?

Thanks a lot in advance
