Complicated sentences

Which of these sentences is correct:

1-There is a man there whom I don't want to see me.
2-There is a man there who I don't want to see me.
3-There is a man there that I don't want to see me.
4-There is a man there I don't want to see me.

Meaning: There is a man there I don't want to be seen by.
I think "1" is wrong and the rest are acceptable although I think the "meaing" sentence is much better than all of them.

Thanks
