S.C. Code Ann. § 33-31-1103 – Action on plan by board, members, and third persons

(a) Unless this chapter, the articles, or bylaws require a greater vote or voting by class, a plan of merger to be adopted must be approved:
1. (1) by the board;
2. (2) by the members, if any, by two-thirds of the votes cast or a majority of the voting power, whichever is less; and
3. (3) in writing by any person whose approval is required by a provision of the articles authorized by Section 33-31-1030 for an amendment to the articles or bylaws.
(b) If the corporation does not have members, or does not have members entitled to vote on the merger, the merger must be approved by a majority of the directors in office at the time the merger is approved. In addition, the corporation shall provide notice of any directors' meeting at which such approval is to be obtained in accordance with Section 33-31-822(c). The notice also must state that the purpose, or one of the purposes, of the meeting is to consider the proposed merger.
(c) If the board seeks to have the plan approved by the members at a membership meeting, the corporation shall give notice to its members of the proposed membership meeting in accordance with Section 33-31-705. The notice also must state that the purpose, or one of the purposes, of the meeting is to consider the plan of merger and contain or be accompanied by a copy or summary of the plan. The copy or summary of the plan for members of the surviving corporation shall include any provision that, if contained in a proposed amendment to the articles of incorporation or bylaws, would entitle members to vote on the provision. The copy or summary of the plan for members of the disappearing corporation shall include a copy or summary of the articles and bylaws that will be in effect immediately after the merger takes effect.
(d) If the board seeks to have the plan approved by the members by written consent or written ballot, the material soliciting the approval shall contain or be accompanied by a copy or summary of the plan. The copy or summary of the plan for members of the surviving corporation shall include any provision that, if contained in a proposed amendment to the articles of incorporation or bylaws, would entitle members to vote on the provision. The copy or summary of the plan for members of the disappearing corporation shall include a copy or summary of the articles and bylaws that will be in effect immediately after the merger takes effect.
(e) Approval by a class of members is required on a plan of merger if the plan contains a provision that, if contained in a proposed amendment to articles of incorporation or bylaws, would entitle the class of members to vote as a class on the proposed amendment under Section 33-31-1004 or 33-31-1022. The plan is approved by a class of members by two-thirds of the votes cast by the class or a majority of the voting power of the class, whichever is less.
(f) After a merger is adopted, and at any time before articles of merger are filed, the planned merger may be abandoned, subject to any contractual rights, without further action by members or other persons who approved the plan in accordance with the procedure set forth in the plan of merger or, if none is set forth, in the manner determined by the board of directors.
(g) A plan of merger involving either a public benefit or mutual benefit corporation that would terminate all members or any class of members or redeem or cancel all memberships or any class of memberships must meet all the requirements of this chapter and specifically this subsection (g):
1. (i) Before adopting a resolution proposing a plan of merger, the board of a mutual benefit corporation shall give notice of the general nature of the amendment to the members.
2. (ii) After adopting a resolution proposing such a plan of merger, the notice to members proposing the merger shall include one statement of up to five hundred words opposing the proposed plan of merger if the statement is submitted by any five members or members having three percent or more of the voting power, whichever is less, not later than twenty days after the board has voted to submit such to the members for their approval. In public benefit corporations, the production and mailing costs must be paid by the requesting members. In mutual benefit corporations, the production and mailing costs must be paid by the corporation.
3. (iii) Any such plan of merger must be approved by the members by two-thirds of the votes cast by each class.
4. (iv) The provisions of Section 33-31-621 do not apply to any amendment meeting the requirements of this chapter.
