... 4. Linking To This Website
Unless you have a written agreement with us that specifies how you may link to the Site, following are the rules for adding a link to the Site from your website:

* The link may not be used in connection with or appear on a website that a reasonable person might consider offensive, obscene, defamatory or otherwise malicious
* We reserve the right to revoke consent to the link at any time in our sole discretion. If we revoke such consent, you agree to immediately remove and disable any and all of your links to the Site ...
