My condolences to you for the loss of your husband.
Since this your first post on iHub you might want to spend time reading through the information which is available when you entered EXS or EXSFF.
A person who did significant due dilegence who does not post here anymore is Dan D. go to his web site "The Fundamental View" blog http://thefundamentalview.blogspot.com/ search for "EXS Due Diligence" (about 12 page downs in the extreme right side of the window.)
The Due Diligence from Dan D. That got me started on the stock. It is a lot of reading with some nice maps. I counted 11 sections (posting dates) and was only half way through. These are in date sequence so you might want to start at the bottom and read them going up datewise. First one is 8/3/09
