The original deal between Altria and Lexaria states:
"Altria is funding a milestone-based research & development program (“R&D Program”) in exchange for a minority equity interest in Lexaria Nicotine and certain DehydraTECH™ license rights. Altria will provide initial funding of US$1 million, with the option for additional funding of up to US$12 million through multiple phased private financings".
Hopefully, that's all the ownership Altria get until they make a decent offer. I'd personally like to see some big royalty revenues for a couple of years and then a buy out.
