yes, but that is why it's called an option agreement - PRB has given up 55% with an explicit understanding of LSG's obligations to the venture - they have not met their obligation - it's not a matter of being in a hurry - why don't we just mothball the LSG JV for 5 years?? This agreement with LSG whereby PRB has given up 55% interest makes little sense, since LSG isn't willing to meet their obligations under the option agreemnet.
