I am a newbie in the domain game, but so much I know, you better get rid of that name fast! Offer it to PepsiCola as a gift (don't ask for money or compensation!) maybe they are gracious enough to give you something for it.
But as I said, I am not an expert and my advice above should be backed up by a consultation with a lawyer.
You got a bomb on your hands here! See that it doesn't explode in your hand.
