MODEL PENAL CODE
(1) Definition of Attempt. A person is guilty of an attempt to commit a crime if, acting with the kind of culpability otherwise required for commission of the crime, he:
(a) purposely engages in conduct which would constitute the crime if the attendant circumstances were as he believes them to be; or
(b) when causing a particular result is an element of the crime, does or omits to do anything with the purpose of causing or with the belief that it will cause such result without further conduct on his part; or
(c) purposely does or omits to do anything which, under the circumstances as he believes them to be, is an act or omission constituting a substantial step in a course of conduct planned to culminate in his commission of the crime.

(4) Renunciation of Criminal Purpose. When the actor's conduct would otherwise constitute an attempt under Subsection (1)(b) or (1)(c) of this Section, it is an affirmative defense that he abandoned his effort to commit the crime or otherwise prevented its commission, under circumstances manifesting a complete and voluntary renunciation of his criminal purpose. The establishment of such defense does not, however, affect the liability of an accomplice who did not join in such abandonment or prevention.
Within the meaning of this Article, renunciation of criminal
purpose is not voluntary if it is motivated, in whole or in part, by circumstances,
not present or apparent at the inception of the actor's course of conduct,
which increase the probability of detection or apprehension or which make
more difficult the accomplishment of the criminal purpose. Renunciation
is not complete if it is motivated by a decision to postpone the criminal
conduct until a more advantageous time or to transfer the criminal effort
to another but similar objective or victim.
Section 5.02. Criminal Solicitation.
(1) Definition of Solicitation. A person is guilty of solicitation to commit a crime if with the purpose of promoting or facilitating its commission he commands, encourages or requests another person to engage in specific conduct which would constitute such crime or an attempt to commit such crime or which would establish his complicity in its commission or attempted commission.
* * *
of Criminal Purpose. It is an affirmative
defense that the actor, after soliciting another person to commit a
crime, persuaded him not to do so or otherwise prevented the commission
of the crime, under circumstances manifesting a complete and voluntary
renunciation of his criminal purpose.
Section 5.03. Criminal Conspiracy.
(1) Definition of Conspiracy. A person is guilty of conspiracy with another person or persons to commit a crime if with the purpose of promoting or facilitating its commission he:
(a) agrees with such other person or persons that they or one or more of them will engage in conduct which constitutes such crime or an attempt or solicitation to commit such crime; or
(b) agrees to aid such other person or persons in the planning or commission of such crime or of an attempt or solicitation to commit such crime.
* * *
(6) Renunciation of Criminal Purpose. It is an affirmative defense that the actor, after conspiring to commit a crime, thwarted the success of the conspiracy, under circumstances manifesting a complete and voluntary renunciation of his criminal purpose.
(7) Duration of Conspiracy. For purposes of Section 1.06(4):
(a) conspiracy is a continuing course of conduct which terminates when the crime or crimes which are its object are committed or the agreement that they be committed is abandoned by the defendant and by those with whom he conspired; and
(b) such abandonment is presumed if neither the defendant nor anyone with whom he conspired does any overt act in pursuance of the conspiracy during the applicable period of limitation; and
(c) if an individual abandons the agreement, the
conspiracy is terminated as to him only if and when he advises those with
whom he conspired of his abandonment or he informs the law enforcement
authorities of the existence of the conspiracy and of his participation
Section 241.1. Perjury.
(1) Offense Defined. A person is guilty of perjury, a felony of the third degree, if in any official proceeding he makes a false statement under oath or equivalent affirmation, or swears or affirms the truth of a statement previously made, when the statement is material and he does not believe it to be true.

(4) Retraction. No person shall be guilty of an offense under this Section if he retracted the falsification in the course of the proceeding in which it was made before it became manifest that the falsification was or would be exposed and before the falsification substantially affected the proceeding.
