RE:Regardless Nobody will offer anything on the 13th hour because the books are closed. Shareholders, at least some of them, voted Yes or No on the proposed deal, even if you qualified on many occasions this transaction as horrible. Again, it is too late to send any message refusing this horrible deal.
Concerning the rights offering, you will have until the end of February to exercise them. In your case, you will have the possibility to buy near 61,000 shares of Terranueva at 0.64 cents. I presume that you will do it if the stock is much higher than 0.64 cents; otherwise, it won't make any sense to exercise those rights.
Now, if the stock is higher or much higher than 0.64 cents before the end of February, you will have the possibility to sell your actual position or a part of it and take the money to exercise your rights. Even if you are frustrated, don't discard too fast the possibility that you have been wrong since the beginning.
Of course, I presume that the Yes will win the derby; we will find out in two days.
