Considering that the founders will be taking positions at facebook, these 'side deals' appear to be closer to salary/compensation negotiations than anything else. Just because you invested in a company, it doesn't mean you own the founders. While the company may not have succeeded, these guys are probably very valuable assets and should be compensated by FB accordingly.
