Better CTAs for ‘Save & exit’ and ‘Save & done’?

I’ve got a bit of a language block for the final stage of a form-filling journey where the user can either

  1. Save what they’ve done, quit and return later
  2. Save what they’ve done and lock it so no further changes can be made.

Save and exit kinda works for 1., but I can’t come up with a suitable unambiguously different label for 2.

Send is the closest, but no sending is involved – this is simply marking the work as ‘complete’ and putting it in a read-only state.

Save & exit and Save & done aren’t sufficiently different to me – anyone got anything better..?
