These are Z clause amendments and you should look at your amendments to see how these will be applied.
Slightly strange they are in data part 2, I would have expected them to state in data part 1 how much notice you need to give if you plan to swap a Key Person, and how much compensation event you will have to pay if you have to swap a key person for a reason not stated in the contract. I doubt they are asking you to offer these as part of your competitive bid? You are unlikely to offer a long notice period or large sum of compensation if you have the choice!
If in doubt or not clear - ask them what they expect!
