Delivery of an executed signature page to this Amendment by facsimile or other electronic transmission (including, without limitation, by

Adobe portable document format file (also known as a “PDF” file)) shall be as effective as delivery of a manually signed counterpart of this Amendment.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed by their respective officers thereunto duly authorized, as of the date first above written.
