"only do it if you actually get a deal"
It's a little bit more nuanced than that. Read this:
The Option shall vest only upon the occurrence of either of the following:
(i) I enter into a binding agreementregarding my Business with a shark within two (2) years of the date of my presentation to the shark.
(ii) the initial exhibition of an episode of the Series that includes my presentation to the sharks (or a portion thereof sufficient toallow a reasonable person to identify the name and nature of my Business).
It seems to me that the 2nd section here says that the royalty/equity options also vest if you get a deal from someone else after the show airs, if they can say that the new investor only found out about you from your appearance on shark tank.
