Maryland Code, Corporations and Associations § 10-502

(a)(1) Except as provided in the partnership agreement, a limited partner is obligated to the limited partnership to perform any promise set forth in the partnership agreement to contribute cash or property or to perform services, even if he is unable to perform because of death, disability, or any other reason.

(2) If a limited partner does not make the required contribution of property or services, he is obligated at the option of the limited partnership to contribute cash equal to that portion of the value (as stated in the partnership agreement) of the stated contribution that has not been made.

(b)(1) The obligation of a limited partner to make a contribution or return money or other property paid or distributed in violation of this title may be compromised only upon compliance with the partnership agreement or, if the partnership agreement does not so provide, with the consent of all partners.

(2) Any compromise does not affect the rights to enforce the original obligation of any creditor of a limited partnership who extends credit, or whose claim arises, after the effective date of the execution of the partnership agreement which reflects the obligation, but before the amendment of the partnership agreement which reflects the compromise.
