(2) On the occurrence of events specified in the Articles of Organization or Regulations to cause dissolution.

(4) Except as otherwise provided in the Regulations, upon the death, retirement, resignation, expulsion, bankruptcy, or dissolution of a Member, or the occurrence of any other event which terminates the continued membership of a Member in the Limited Liability Company, unless there is at least one remaining Member and the business of the Limited Liability Company is continued by the consent of the number of Members or class thereof stated in the Articles of Organization or Regulations of the Limited Liability Company or if not so stated, by all remaining Members.

(A) On the winding up of a Limited Liability Company, its assets shall be paid or transferred as follows:

The statement of intent to dissolve shall be executed by a Manager of the Limited Liability Company.

(1) For the difference between the amount of the Member’s contributions to capital which have been actually made and the amount which is stated in the Articles of Organization or other contract as having been made; and

(2) For any unpaid contribution to capital which the Member, in the Articles of Organization or other contract, agreed to make in the future at the time and on the conditions stated in the Articles of Organization or other contract.

(1) Specific property which is stated in the Articles of Organization or other contract as having been contributed by such Member, but which property was not contributed or which property has been wrongfully or erroneously returned; and

(2) Money or other property wrongfully paid or conveyed to such Member on account of the Member’s contribution.

(C) The liabilities of a Member as set out in this section may be waived or compromised only by the consent of all Members, but a waiver or compromise shall not affect the right of a creditor of the Limited Liability Company who extended credit or whose claim arose after the filing and before a cancellation or amendment of the Articles of Organization or other contract to enforce such liabilities.

(D) When a contributor has rightfully received the return in whole or in part of the capital of the Member’s contribution, the contributor is still liable to the Limited Liability Company for any sum, not in excess of the return with interest, necessary to discharge its liability to all creditors of the Limited Liability Company who extended credit or whose claims arose before such return.

Debts, liabilities and other obligations may be contracted for or incurred on behalf of a Limited Liability Company, by any Member or Members, if management of the Limited Liability Company is retained by the Members.

Neither the Members of the Limited Liability Company nor the Manager(s) or Officers of the Limited Liability Company are liable for debts, obligations or liabilities of the Limited Liability Company.

Distributions of cash or other assets of a Limited Liability Company shall be made to the Members in the manner provided by the Regulations. If the Regulations do not otherwise provide, distributions shall be made on the basis of the agreed value, as stated in the records required to be kept under Section 2.22 of the Texas Limited Liability Company Act of the contributions made by each Member.

Except as otherwise provided by this Article, a Member is entitled to receive distributions from a Limited Liability Company before the Member’s withdrawal from the Limited Liability Company and before the winding up of the Limited Liability Company to the extent and at the times or on the occurrence of the events specified in the Regulations.

(A) In settling accounts after dissolution, the liabilities of the Limited Liability Company shall be entitled to payment in the following order of priority:

(1) Those liabilities to creditors, in the order of priority as provided by law, except those liabilities to Members of the Limited Liability Company on account of their contributions;

(2) Those liabilities to Members of the Limited Liability Company in respect of their shares of the profits and other compensation by way of income on their contributions; and

(3) Those liabilities to Members of the Limited Liability Company in respect of their contributions to capital.
