With respect to all matters of Oregon law, we note that you have received an opinion, dated March 27, 2020, of Ann M. Miller, Vice President, Corporate Secretary and Chief Ethics & Compliance Officer of the Company.

In rendering the foregoing opinion, we have assumed, without independent verification, that the Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Oregon, that the Indenture, dated April 26, 2013, as supplemented by the Fourth Supplemental Indenture, dated March 27, 2020 (together, the “Indenture”), relating to the Securities, in each case, between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), was duly authorized, executed and delivered by the Company insofar as the laws of Oregon are concerned and that all corporate action by the Company related to the Securities was duly authorized as a matter of Oregon law.
