(b) However, if a person abandons the agreement a conspiracy is terminated as to him or her only, when the person:
(1) Advises other persons with whom the person conspired of his or her abandonment; or
(2) Informs a law enforcement authority of the existence of the conspiracy and of his or her participation in the conspiracy.
