Oregon Revised Statutes Insurance § 743.168

(1) A life insurance policy shall contain a provision that the policy shall be incontestable after it has been in force for two years from its date of issue during the lifetime of the insured, except for nonpayment of premiums. At the option of the insurer the two-year limit within which the policy may be contested shall not apply to the provisions for benefits in the event of total and permanent disability and provisions which grant additional insurance specifically against death by accident.

(2) A provision in a life insurance policy providing that such policy shall be incontestable after a specified period shall preclude only a contest of the validity of the policy, and shall not preclude the assertion at any time of defenses based upon provisions in the policy which exclude or restrict coverage, whether or not such restrictions or exclusions are excepted in such provision.
