Liability for contribution.

A. Except as provided in the articles of organization or an operating agreement, a member's written promise to the limited liability company to contribute cash or property or render services is not excused by reason of the member's death, disability or other inability to perform. B. The articles of organization or an operating agreement may provide that the interest of a member who fails to make a payment of cash or transfer of property to the limited liability company or fails to render services required by a written promise is subject to specified consequences. Such consequences may take the form of a reduction of the defaulting member's interest in the limited liability company, subordination of the member's interest to that of nondefaulting members, a forced sale of the member's interest, forfeiture of the member's interest, the lending of money to the defaulting member by other members of the amount necessary to meet the defaulting member's commitment, a determination of the value of a defaulting member's interest by appraisal or by formula and redemption or sale of the interest at that value, or any other specified consequence. Unless otherwise provided by the articles of organization or an operating agreement, a member who does not perform a written promise to contribute cash or property or render service shall be obligated, at the option of the limited company, to contribute cash equal to the fair market value of that portion of the promised performance that has not been received by the limited liability company. C. Unless otherwise provided in the articles of organization or an operating agreement, the obligation of a member to make a contribution may be compromised only with the unanimous consent of the members.
