Pennsylvania Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act pertain to specific provisions of company mergers and share exchanges. Although Pennsylvania is not explicitly mentioned in the provided context, assuming its inclusion is unintended, we will focus solely on Minnesota. Section 302A.471 of the Minnesota Business Corporation Act deals with the process of mergers and share exchanges involving parent corporations that own at least 90% of the outstanding shares of a subsidiary corporation. This section lays out the requirements and procedures necessary for such transactions to take place. It emphasizes the need for shareholder approval, with a majority vote from each corporation involved being necessary to proceed. The section also highlights the need for comprehensive notices to be provided to shareholders, detailing the terms of the proposed merger or share exchange, thereby ensuring transparency and allowing shareholders to make informed decisions. Lastly, Section 302A.471 establishes the duration of corporate existence following the transaction, outlining the rules regarding its continuity or dissolution. Section 302A.473 of the Minnesota Business Corporation Act delves into more specific aspects of the merger or share exchange process. This section focuses on the rights of shareholders who oppose the proposed transaction, allowing dissenting shareholders to take certain actions. These actions include exercising appraisal rights, which entitle a shareholder to receive the fair value of their shares, as determined by the court, or demanding the payment of an alternative fair value if their shares are not marketable. Additionally, Section 302A.473 provides guidance on the process and requirements for dissenting shareholders to assert their rights, including important deadlines, notice requirements, and documentation submission. While Pennsylvania was mistakenly included in the requested context, it is worth mentioning that the corresponding sections in Pennsylvania's business corporation law are not labeled as 302A.471 and 302A.473, as these are specific to the Minnesota Business Corporation Act.
