The trick in any multiplayer game where you can lose is to pit the two biggest opponents against each other and scrap the loser. Law is most definately a multiplayer game. :)

Legally, this is tricky but possible, IMHO (though IANAL, thank Chao). Does $COMPANY already have a bad reputation? If so, seek the help of advocacy groups such as the Better Business Bureau, or attempt to get in touch with law enforcement -- if the CEO is doing this to you, the CEO may be doing it to someone else.

Similarly, consider the possibility of enlisting a (hopefully) more honorable corporate sponsor in some fashion -- set up a licensing agreement with someone who has got the legal capability to reduce $COMPANY to litigious cinders, and sit back to watch the fireworks.

Keep in mind that IANAL. (Although if you do see a hefty settlement through these techniques, then by reading this post you've already agreed to my EULA (End-User Legal Agreement) and therefore owe me 5% of all monies recieved. ;) )
