To whom it may concern:

I am writing to express my strong disagreement with the CBOE's arbitrary elimination of my exerciser right. I bought my membership at a premium to other memberships based on their agreement to my exercise right. At present I don't want it eliminated at my expense and their arbitrary benefit. If it is eliminated the least they can do is give me fair value decided by an impartial court.
