The Secretary of the State shall file one copy of such process and keep a record of the date and hour of such receipt, and, within two business days after such service, forward by registered or certified mail the other copy of such process to the foreign limited liability company at the address of the office designated in the application for registration filed pursuant to subdivision (4) of section 34-275b.

The address of the principal office shall be as shown on the company's or foreign company's most recent annual report filed by the Secretary of the State. Service is effected under this subsection on the earliest of: (1) The date the company or foreign company receives the mail or delivery by the commercial delivery service; (2) the date shown on the return receipt, if signed by the company or foreign company; or (3) five days after its deposit with the United States Postal Service, or with the commercial delivery service, if correctly addressed and with sufficient postage or payment.
