Sec. 23. This chapter does not apply to any business combination of a resident domestic corporation with an interested shareholder of the resident domestic corporation who became an interested shareholder inadvertently, if the interested shareholder:
(1) as soon as practicable, divests itself of a sufficient amount of the voting shares of the corporation so that it no longer is the beneficial owner (directly or indirectly) of ten percent (10%) or more of the outstanding voting shares of the resident domestic corporation; and
(2) would not at any time within the five (5) year period preceding the announcement date with respect to the business combination have been an interested shareholder but for the inadvertent acquisition.
