A sale, lease, exchange, mortgage, pledge or other disposition of all, or substantially all, the property and assets of a nonprofit corporation may be made upon the terms and conditions and for the consideration, which may consist in whole or in part of money or property, real or personal, including shares of any corporation for profit, domestic or foreign, as may be authorized in the following manner:
(1) If there are members entitled to vote thereon, the board of directors shall adopt a resolution recommending the sale, lease, exchange, mortgage, pledge or other disposition and directing that it be submitted to a vote at a meeting of members entitled to vote thereon, which may be either an annual or a special meeting. Written notice stating that the purpose, or one of the purposes, of the meeting is to consider the sale, lease, exchange, mortgage, pledge, or other disposition of all, or substantially all, the property and assets of the nonprofit corporation shall be given to each member entitled to vote at the meeting, within the time and in the manner provided by this chapter for the giving of notice of meetings of members. At the meeting the members may authorize the sale, lease, exchange, mortgage, pledge, or other disposition and may fix, or may authorize the board of directors to fix, any or all of the terms and conditions thereof and the consideration to be received by the nonprofit corporation therefor. The authorization shall require at least two-thirds of the votes entitled to be cast by members present or represented by proxy at the meeting. After the authorization by a vote of members, the board of directors, nevertheless, in its discretion, may abandon the sale, lease, exchange, mortgage, pledge, or other disposition of assets, subject to the rights of third parties under any contracts relating thereto, without further action or approval by members.
(2) If there are no members, or no members entitled to vote thereon, a sale, lease, exchange, mortgage, pledge, or other disposition of all, or substantially all, the property and assets of a nonprofit corporation shall be authorized upon receiving the vote of a majority of the directors in office.
