Review and update of IP contract for software development project

The client has come back with some further changes that his lawyer has made.

This is what he said:

"My lawyer is happy to have different classifications of code but consequently requires additional legal language to ensure that any potential ‘angel investor’ is assured that the software can be distributed and sold without hindrance."

Please see the amended document attached.

Apparently, I have to fill in Schedule 1, so that is part of what I need help doing from you.

Additionally, i informed the client that it was unlikely I would be able to agree to assigning exclusive rights over the the client for my pre-existing work and work that was based on my previous work - which is what some of their new amendments seem to ask for.

My client responded: "Your comments on the Exclusive license seem quite reasonable to me so alternative wording is welcome."

So, I need help on this point too.

Personally, i think the wording you came up with last time was perfect and I'm now a bit confused as to what the new amendments amount to.
