Hello, Syednasir:
I have good news: I notice that Mr. Antonson has returned to posting. Hopefully, he will soon post a diagram of your sentence.
I do not know how to post diagrams, so I can only use some clumsy words:
1. "Clearly" in your sentence -- as the other posters told you -- is a sentence adverb. It modifies the whole sentence.
So it should be placed on a horizontal line above the whole sentence.
2. "you to sign a contract" is a so-called infinitive phrase. It is the direct object of "want." There are two different
ways to diagram it. As I said, I cannot post a diagram to show you and it is impossible to explain in words.
Let's hope that Mr. Antonson soon helps us.
James
