What charges are levied if option positions get exercised?

The Securities Transaction Tax (STT) on an option that is bought and exercised is 0.125% of the option's intrinsic value. If options were shorted, an STT of 0.1% of the premium would have been paid, so there would be no STT if this position expires.
