A guarantee may be given by a corporation, although not in furtherance of its corporate purposes, when authorized at a meeting of shareholders by two-thirds of the votes of all outstanding shares entitled to vote thereon. If authorized by a like vote, such guarantee may be secured by a mortgage or pledge of, or the creation of a security interest in, all or any part of the corporate property, or any interest therein, wherever situated.
