No fractional shares will be issued in connection with the reverse stock split. In the event that the number of shares of post-split common stock for any shareholder includes a fraction, such fractional shares will be rounded up to the nearest whole share. Ownership percentages are not expected to change meaningfully as a result of rounding up fractional shares that result from the exchange. Similarly, no fractional shares will be issued on the exercise of outstanding options or rights, except as otherwise expressly specified in the documents governing such options or rights.
