Tab content is only a single link

One page of my website has several different related tabs. One of those tabs, however, only will contain a single link to an external site, which makes the page seem very empty when that tab is active.

One suggestion was to have the tab be a "dummy tab" that instead of acting as a tab usually does (show new content), would actually be a link to that external site.

Which of those two options (mostly empty tab content, tab as a link) is better? Or are there any other ideas that would work better?
