The merger rumor died when shares were revoked.
The merger rumor was almost plausible in 2011 if Jade was worth $20 million, NuVax was a valid spinoff possibility, and India annual revenues were going to be $10 - $12 million in 2011.
Unfortunately, we learned in 2012 that Jade was worth nothing, NuVax evaporated and was worthless, and India Revenues turned out to be zero.
As a result, the merger rumor became implausible in 2012. However, buyout rumors that can't be absolutely proven false always have a tiny thread of life in the world of zombie biotechs.
Unfortunately, RXPC changed from being a zombie biotech to being nothing when the company declared itself insolvent, share registration was revoked, the directors and officers quit and appointed new Directors and Officers from a different continent, and the new Directors and Officers removed all means of communication and disappeared.
[bAs a result, the merger rumor is dead. It's not "mostly dead," it is DEAD.
