How do I extract a 5 digit zip code from a column that may have a random number of text?

Thanks for the tip.

So attached is a sample workbook of what I'll be working on. As you can see under the "notes" column, there is a body of text with the zip code. I want to be able to extract only the zip code shown to the row over to the right (column E)

Thanks to everybody for the help so far.
