(2) A person who conspires to commit more than one (1) crime, all of which are the object of the same agreement or continuous conspiratorial relationship, is guilty of only one (1) conspiracy.

(3) If a person guilty of conspiracy, as defined by KRS 506.040, knows that a person with whom he conspires to commit a crime has conspired with another person or persons to commit the same crime, he is guilty of conspiring to commit the crime with the other person or persons, whether or not he knows their identity.
(4) No person may be convicted of conspiracy to commit a crime when an element of that crime is agreement with the person with whom he is alleged to have conspired or when that crime is so defined that his conduct is an inevitable incident to its commission.
