Answer

The person who is witnessing the signature signs the bottom part. Most signatures have to be witnessed, on most documents.

Answer

You can be more specific than 'signs'. What you can ask is 'who usually witnesses a contract?'. 
That probably depends on local law - so you should ask a lawyer who can do it. 
Presumably a lawyer can? 
I think that here, anyone can witness it, although they might need to be independent of the company.
