Notwithstanding any provisions to the contrary in § 7-6-50 — § 7-6-55, upon termination of the corporation, title to all funds and other properties owned by it which remain after provision for the payment or satisfaction of all bonds, certificates of indebtedness, promissory notes, and other obligations of the corporation shall be transferred to and shall vest in the sinking fund as provided in chapter 8 of Title 35. Net proceeds, after expenses, arising from any assets and legal settlements that have reverted to the sinking fund shall be deposited into the sinking fund as provided in chapter 8 of Title 35.
