The exhibits to the filing only needs to contain enough to establish cause for the complaints made.

There's no reason to attach everything you've got to an initial complaint, and a lot of good reason to wait until you see how the other side responds. If they want to settle, for example, the less you've had to disclose in public, the easier it might be.

So while they very well may not have had a contract, this confirms no such thing.
