Not really. At worst you lose a couple of years of growth in prior equity grants but your yearly refresher will be bulked up significantly to account for the diminished value of the stock and voila, pleb no more...
Yup, if the stock goes down, and you get a bigger (# of shares, not $$) refresh, if it goes back up to where it was before, bam, you've got it made. If you're lucky, you'll have enough for a down payment on a house....
