Stock); provided, however, that if either (a) such Person acquires beneficial ownership of additional shares of Common Stock such that such Person becomes the Beneficial Owner of fifteen percent (15%) or more of the shares of Common Stock then outstanding, or (b) such Person is the Beneficial Owner of ten percent (10%) or more but less than fifteen percent (15%) of the shares of Common Stock then outstanding and reports or is required to report such ownership of shares of Common Stock on Schedule 13D under the Exchange Act (or any comparable or successor report) which Schedule 13D reports the intention to or reserves the right to control or influence the management or policies of the Company or engage in any of the actions specified in Item 4 of such schedule (other than the disposition of the Common Stock), then such Person shall become an Acquiring Person immediately.
