Some technical notes on this MOU. This isn't a paper document that was signed. Its electronic.
You'll notice on the top that there is statement about a DocuSign Envelope ID. This is a DocuSign document. DocuSign is an electronic signature company. You'll also note that Greg Schiano's signature says DocuSigned around his signature. That means he open a link to this, usually sent by email, typed in his name, and the signature you see is generated. By law that's the same as typing you name - I deal with these things at work semi-regularly, and its clear that's a legal signature.
Currie's signature is hard to tell on. There is not a DocuSigned statement around it. That said, it lines up nearly perfect. I suspect the contract was generated by lawyers, signed by John Currie in some other electronic medium, then embedded as an image when it was generated by DocuSign. Everything is centered too well for him to have signed a manual copy of this thing. Generally physical signing and scanning results in tilts in formatting. This is perfect centering, computers do that, not people. Again, still Currie's signature legally however it was placed there.
Beyond that, it also means Schiano might have received this with some other document or email text in conjunction with this that stated the UT contract policy. He might not have. You can't tell from this. Dates, times executed, other linked documents, etc. could all be tied to this thing. Main point being there may be more directly and demonstrably connected to this thing than what you are seeing here that could easily be used in a court case to support or negate some of the debate going on regarding its validity. The lawyers would have to weigh in on that. Mainly wanted it to be clear this thing has Metadata and maybe additional data not visible.
One last consideration. Because its a DocuSign, there is the possibility of a multi-step electronic routing sign off that automatically kicks to Davenport, CFO, etc. via an electronic approval process. Again, you wouldn't see it here. That magic DocuSign electronic Envelope section might have it though.
