| A sex offender or sexually violent predator who fails to |
| register or update the information required under this chapter |
| commits a Class D crime, except that a violation of this section |
| when the sex offender or sexually violent offender has 2 or more |
| prior convictions in this State for violation of this chapter is |
| a Class C crime.__For purposes of this section, the dates of both |
| of the prior convictions must precede the commission of the |
| offense being enhanced by no more than 10 years, although both |
| prior convictions may have occurred on the same day.__The date of |
| the conviction is deemed to be the date that sentence is imposed, |
| even though an appeal was taken.__The date of a commission of a |
| prior offense is deemed to be that stated in the complaint, |
| information or indictment, notwithstanding the use of the words |
| "on or about" or the equivalent.__It is an affirmative defense |
| that the failure to register or update information resulted from |
| just cause. |
