This stock reminds me of SIRI which was also about to get de-listed for not being over 1 dollar. SIRI is now doing fine.
My only concerns are any possible losses due to the drug being disapproved by the FDA in June and closer to that public panic due to the earnings statement on May 3rd.
Pluspoints are assets did increase last quarter (Dec 09) and liabilities went down http://finance.yahoo.com/q/bs?s=SNSS so it seems this new drug is a key factor.
In addition and my opinion only is that today's sell of was due because we had already reached and crossed above the upper BB so a pullback and more support never hurts (which seems to be the .90 area and below that .85)
Couple more days should start pulling back up IMO unless there is a gap like SNTS which I hope not
