Oregon Revised Statutes Insurance § 743.258

If any statement other than those relating to age, sex and identity are required as a condition to issuing an annuity or pure endowment policy, the policy shall contain a provision that the policy shall be incontestable after it has been in force during the lifetime of the person or of each of the persons as to whom such statements are required, for a period of two years from its date of issue, except for nonpayment of stipulated payments to the insurer. At the option of the insurer the two year limit within which the policy may be contested shall not apply to any provisions relative to benefits in the event of disability and any provisions which grant insurance specifically against death by accident or accidental means.
