That's why I paid the 30 cents for the call without the second obligation.  It's still a great deal for me, since I couldn't buy that call for that.  I sold some December corn last fall for $3.65 that came with a July '08 call for 10 cents and a second obligation for corn this fall if the market is above $5 for November.  Seemed good at the time, but now I have a pretty good chance at delivering that corn for $5 (minus basis) when it may be worth a lot more.  That's ok with me, but I didn't want to lock in any more and I still wanted the price floor with a chance at capturing any more increase in the market.
