rules

in a live game if the dealer or another player happens to flip one of my hole cards while dealing or before play has started i would normally get the burn card unless in the blind. this is the rule i have seen used in variouse live games. now what is the rule if i accidently flip one of my own hole cards lets say before the flop? Do i have to keep that card, do i get the burn, or do i have to muck my hand? Can someone please help.

A penalty may be given (though it is unlikely if the exposure was accidental) but the player is not entitled to another card and the hand is not declared dead.
