I don't know anything except what I read in press releases and filings and what I see on the message boards. I just don't know why he would sell now. No other insiders with very recent sales, and all the reports we see seem positive. I really have no knowledge about his personal feelings toward the company.
He helped bring the company to the Amex and was rewarded with his current shares and a seat on the board. After the company made a secondary offering in the fall of '07 at $5, he resigned/was removed from the board. Now he's selling PLX a buying shares of LTS and OPK.
