      of state before submitting the statement for filing. You also may e-mail
      an inquiry to corpinfo@sos.state.tx.us. As information on out-of-state
      financial institutions is maintained on a separate database, a financial
      institution must call (512) 463-5701 to verify registered agent and
      registered office information. If the information on the form is
      inconsistent with the records of this office, the statement will be
      returned.

2.    You are required by law to provide a street address in item 4 unless the
      registered office is located in a city with a population of 5,000 or less.

      limited partnership. A person commits an offense under the Texas Business
      Corporation Act, the Texas Non-Profit Corporation Act or the Texas Limited
      Liability Company Act if the person signs a document the person knows is
      false in any material respect with the intent that the document be
      delivered to the secretary of state for filing. The offense is a Class A
      misdemeanor.
