What happens if you exercise a futures call option?

i understand that if you exercise a call option on stocks, you can purchase the stocks for the strike price which is below the stock's market value, consequently getting a profit. But i am confused as to how futures would work in this manner.|||The buyer of a call option acquires the right but not the obligation to purchase (go long) a particular futures contract at a specified price at any time during the life of the option. Each option specifies the futures contract which may be purchased (known as the "underlying" futures contract) and the price at which it can be purchased (known as the "exercise" or "strike" price). A March Treasury bond 84 call option would convey the right to buy one March U.S. Treasury bond futures contract at a price of $84,000 at any time during the life of the option. One reason for buying call options is to profit from an anticipated increase in the underlying futures price. A call option buyer will realize a net profit if, upon exercise, the underlying futures price is above the option exercise price by more than the premium paid for the option. Or a profit can be realized it, prior to expiration, the option rights can be sold for more than they cost. Example: You expect lower interest rates to result in higher bond prices (interest rates and bond prices move inversely). To profit if you are right, you buy a June T-bond 82 call. Assume the premium you pay is $2,000. If, at the expiration of the option (in May) the June T-bond futures price is 88, you can realize a gain of 6 (that's $6,000) by exercising or selling the option that was purchased at 82. Since you paid $2,000 for the option, your net profit is $4,000 less transaction costs. As mentioned, the most that an option buyer can lose is the option premium plus transaction costs. Thus, in the preceding example, the most you could have lost--no matter how wrong you might have been about the direction and timing of interest rates and bond prices--would have been the $2,000 premium you paid for the option plus transaction costs. In contrast if you had an outright long position in the underlying futures contract, your potential loss would be unlimited. It should be pointed out, however, that while an option buyer has a limited risk (the loss of the option premium), his profit potential is reduced by the amount of the premium. In the example, the option buyer realized a net profit of $4,000. For someone with an outright long position in the June T-bond futures contract, an increase in the futures price from 82 to 88 would have yielded a net profit of $6,000 less transaction costs. Although an option buyer cannot lose more than the premium paid for the option, he can lose the entire amount of the premium. This will be the case if an option held until expiration is not worthwhile to exercise.|||If you exercise a futures call option, you will receive ownership of the underlying futures contract. Once you own the futures contract, you can decide if you want to sell it, or exercise. A futures option is just a derivative of a derivative, so the mechanics of exercise and assignment are the same except for the fact that you are one more step removed from the underlying security.|||Is there a futures option??
