(a) Except as provided in subsection (b), a person who makes a contribution to a partnership and erroneously but in good faith believes that he has become a limited partner in the partnership is not a general partner in the partnership and is not bound by its obligations by reason of making the contribution, receiving distributions from the partnership or exercising any rights of a limited partner, if, within a reasonable time after ascertaining the mistake:

(1) In the case of a person who wishes to be a limited partner, he causes, if applicable, a certificate of amendment withdrawing him as a general partner to be executed and filed with the office of the secretary of state and has his interest as a limited partner properly recorded, in the limited partnership's records as required by law and the partnership agreement;

(2) In the case of a person who wishes to withdraw from the partnership, he takes such action as may be necessary to withdraw.

(b) A person who makes a contribution under the circumstances described in subsection (a) is liable as a general partner to any third party who transacts business with the partnership prior to the occurrence of either of the events referred to in subsection (a):

(1) If such person knew or should have known either that no certificate has been filed or that the certificate inaccurately refers to him as a general partner; and

(2) If the third party actually believed in good faith that such person was a general partner at the time of the transaction, acted in reasonable reliance on such belief and extended credit to the partnership in reasonable reliance on the credit of such person.
