Probably 10 or 12 pitch - looking at their source, it doesn't seem as if the font or size was changed from whatever the default was in their web authoring software, only the color and the italics. Arial 12 is a general standard default font for most programs.
I can't tell you what the font is for sure as they are using a cascading style sheet (css). But it looks more like a Times New Roman italics and the should size is 11 as I saw this in the source: font-size: 11px.
So try Times New Roman either 11 or 12 to see if it gets you what you need.
