Oregon Revised Statutes Trade Regulations and Practices § 650.230

Notwithstanding the terms of any franchise, no franchisor may prohibit or prevent the sale, assignment or other transfer of a franchise to a corporation in which the franchisee has and maintains a controlling interest if the franchisee offers in writing personally to guarantee the performance of the obligations under the franchise. In the event of a sale, assignment or transfer under this section, the franchisor may require the corporation to assume in writing all of the franchisee's obligations to the franchisor under the franchise and may require the franchisee to maintain a controlling interest in the corporation and actively operate the marketing premises during the time that the franchise with the corporation continues.
