B. A statement included in the articles of incorporation that "the corporation elects to have preemptive rights" or words of similar import means that the following principles apply except to the extent the articles of incorporation expressly provide otherwise:

1. 1. The shareholders of the corporation have a preemptive right, granted on uniform terms and conditions prescribed by the board of directors, to provide a fair and reasonable opportunity to exercise the right to acquire proportional amounts of the corporation's unissued shares on the decision of the board of directors to issue them.
2. 2. A shareholder may waive his preemptive right. A waiver evidenced by a writing is irrevocable even though it is not supported by consideration.

3. 3. There is no preemptive right with respect to:

   1. (a) Shares issued as compensation to directors, officers, agents or employees of the corporation, its subsidiaries or its affiliates.
   2. (b) Shares issued to satisfy conversion or option rights created to provide compensation to directors, officers, agents or employees of the corporation, its subsidiaries or its affiliates.
   3. (c) Shares authorized in articles of incorporation that are issued within six months from the effective date of incorporation.
   4. (d) Shares issued in transactions for which shareholder approval is required by chapters 1 through 17 of this title.
4. 4. Holders of shares of any class without general voting rights but with preferential rights to distributions or assets have no preemptive rights with respect to shares of any class.
5. 5. Holders of shares of any class with general voting rights but without preferential rights to distributions or assets have no preemptive rights with respect to shares of any class with preferential rights to distributions or assets unless the shares with preferential rights are convertible into or carry a right to subscribe for or acquire shares without preferential rights.
6. 6. Shares that are subject to preemptive rights and that are not acquired by shareholders may be issued to any person for a period of one year after being offered to shareholders at a consideration set by the board of directors that is not lower than the consideration set for the exercise of preemptive rights. An offer at a lower consideration or after the expiration of one year is subject to the shareholders' preemptive rights.
