The governor of this state may also surrender, on demand of the executive authority of any other state, any person in this state charged in such other state in the manner provided in section 570.08 with committing an act in this state or in a third state, intentionally resulting in a crime in the state whose executive authority is making the demand, when the acts for which extradition is sought would be punishable by the laws of this state, if the consequences claimed to have resulted therefrom in the demanding state had taken effect in this state; and the provisions of this article not otherwise inconsistent, shall apply to such cases, even though the accused was not in that state at the time of the commission of the crime, and has not fled therefrom; provided, however, that the governor of this state may, in his discretion, make any such surrender conditional upon agreement by the executive authority of the demanding state, that the person so surrendered will be held to answer no criminal charges of any nature except those set forth in the requisition upon which such person is so surrendered, at least until such person has been given reasonable opportunity to return to this state after his acquittal, if he shall be acquitted, or if he shall be convicted, after he shall be released from confinement. Nothing in this section shall apply to the crime of libel.
