"The Rule does not apply to the underlying transactions or the ability of an investor to buy or sell a security, but rather the ability to publish a quotation, or an “indication of interest,” to the greater investing public."

Conclusion
Your guess is as good as mine.
Maybe cut down on Day Trader volatility with no Level 2 quotes
Probably just be harder to buy/sell GNBT stock

Question
What changed from yesterday to today with GNBT to make the OTC change to the Expert Market??
