As one of those shareholders for 4+ years ago I prefer a deal to be done.  Otherwise I agree, hold the warrants right through expiry if necessary.  Unless the share price gets going soon, I will be saying goodbye to several thousand warrants. 

Right now ( okay a few days ago) I could have bought 2.5 shares for the price of exercising. Y warrants.  Good money after bad.  

I am going to do like Kenny Rogers and hold them. I may end up folding that part of my investment but....  I knew that going in.
