Update NDA PDF Text

I have a short document in PDF format that needs a quick, precise edit. Three specific lines must be replaced with new wording I will supply. The file is not password protected, so you can work directly in Adobe Acrobat, PDF-XChange, or any comparable editor without first unlocking it...
