The link in the email actually goes to sharefile.com where it downloads a file Amendment or the Agreement_09-11-2015.zip containing a malicious execitable Amendment or the Agreement_09-11-2015.scr which has a VirusTotal detection rate of 2/54.
Automated analysis is inconclusive   but you can guarantee that this is nothing good. Because of the low detection rates, it might be worth temporarily blocking sharefile.com.
My sources (thank you!) say that this is Upatre dropping the Dyre banking trojan, dropping a DLL with a 2/55 detection rate. The comments in that report also contain a list of IP address that you might want to block.
