Hailo says Uber blocked potential investors

>He added: "In raising that massive [funding] round, any investor who wanted to even look at Uber's books to decide whether they wanted to make an investment had to sign an agreement which specifically named us, as well as Lyft, and restricting them from having any ability to even talk to us for at least a year.

I'm not very familiar with venture capitalism. This reads to me as if prospective investors wanted to gauge Uber's finances by looking at their books but were forced to sign the agreement first. Is this not the case?
