Warrant info - PRE.WTI just talked to investor relations. It turns out you are NOT forced to exercise the warrants next week. You can hold them through July 2012.
The only difference is you will pay the original exercise price, which I believe is $7.80.
So if you have a big capital gain in the warrants and you are planning to hold the company for the long-term, or if you don't have the liquidity right now, you can just sit tight and hold on to your warrants.
I havn't decided what I'm going to do yet but it's good to know you are not forced to do anything.
