(1) A promise by a member to contribute to the limited liability company is not enforceable unless set out in a writing signed by the member.

(2) A member is obligated to the limited liability company to perform an enforceable promise to contribute cash or property or to perform services, even if the member is unable to perform because of death, disability or any other reason. If a member does not make the required contribution of property or services, the member is obligated at the option of the limited liability company to contribute cash equal to that portion of the value of the stated contribution that has not been made. The foregoing option shall be in addition to, and not in lieu of, any other rights, including the right to specific performance, that the limited liability company may have against the member under the operating agreement or applicable law.

(3) The obligation of a member to make a contribution or return money or other property paid or distributed in violation of this chapter may be compromised only by specific consent of all the members. However, a creditor of a limited liability company who extends credit, or otherwise acts in reliance on that obligation after the member signs a writing that reflects the obligation and before the amendment or cancellation thereof to reflect the compromise, may enforce the original obligation to the same extent as the limited liability company could pursuant to this section. A conditional obligation of a member to make a contribution or return money or other property to a limited liability company may not be enforced unless the conditions of the obligation have been satisfied or waived as to or by such member. Conditional obligations include contributions payable upon a discretionary call of a limited liability company prior to the time the call occurs.

(4) A certificate of formation or operating agreement may provide that the interest of any member who fails to make any contribution that the member is obligated to make, shall be subject to specified penalties for, or specified consequences of, such failure. Such penalty or consequence may take the form of reducing the defaulting member’s proportionate financial or governance interest in the limited liability company, subordinating the defaulting member’s financial or governance interests to that of nondefaulting members, forcing a sale of the defaulting member’s financial or governance interest, forfeiting the defaulting member’s financial or governance interest, the lending by other members of the amount necessary to meet the defaulting member’s commitment, fixing the value of the defaulting member’s financial or governance interest by appraisal or by formula and redeeming or selling of the defaulting member’s financial or governance interest at such value, or other penalty or consequence.
