Defendant was convicted of two counts of sodomy in the first degree, ORS 163.405, after a trial to a jury. He assigns error to the imposition of multiple post-prison supervision terms on the consecutive sentences. Defendant did not object below, and we decline to exercise our discretion to address the alleged error. ORAP 5.45(2); State v. Farmer, 317 Or 220, 856 P2d 623 (1993).

Defendant did object to the imposition of a post-prison supervision term of 20 years, pursuant to ORS 144.103.1 The state concedes that the statute applies only to persons convicted of an offense that occurred on or after September 1, 1991, and that defendant committed the offenses before that date. Both defendant and the state agree that the mandated term of post-prison supervision for the sodomy convictions is 36 months.

Convictions affirmed; remanded with instructions to modify judgment to impose 36-month term of post-prison supervision on sodomy convictions.
