registration to transact business in state.

A. A foreign limited liability company transacting business in

this state may not maintain an action, suit, or proceeding in a

court of this state until it has registered in this state as

provided in this act.

B. The failure of a foreign limited liability company to

register in this state does not impair the validity of any contract

or act of the foreign limited liability company or prevent the

foreign limited liability company from defending any action, suit,

or proceeding in any court of this state.

C. A foreign limited liability company, by transacting business

in this state without registration, appoints the Office of the

Secretary of State as its agent for service of process with respect

to a cause of action arising out of the transaction of business in

this state.

D. A member of a foreign limited liability company is not

liable for the debts and obligations of the limited liability
