ORS 60.457: Effect of amendment.

An amendment to articles of incorporation does not affect a cause of action existing against or in favor of the corporation, a proceeding to which the corporation is a party or the existing rights of persons other than shareholders of the corporation. An amendment changing a corporation’s name does not abate a proceeding brought by or against the corporation in its former name. [1987 c.52 §111]
