privileges or voting power of the Series A Preferred Stock; and provided, further, that (i) any increase in the number of authorized shares of Series A Preferred Stock, (ii) any increase in the number of authorized shares of preferred stock of the Corporation or the creation or issuance of any other class or series of preferred stock or (iii) any increase in the number of authorized shares of any other class or series of preferred stock, in each case ranking on a parity with or junior to the Series A Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers.

8. Term. The Series A Preferred Stock will have a perpetual term and shall not be subject to any sinking fund.

9. No Preemptive Rights. No holder of the Series A Preferred Stock shall, as such holder, have any preemptive rights to purchase or subscribe for additional shares of stock of the Corporation or any other security of the Corporation which it may issue or sell.

The Corporation shall mail the reports to the holders of Series A Preferred Stock within 15 days after the respective dates by which the Corporation would have been required to file the reports with the SEC if the Corporation were then subject to Section 13 or 15(d) of the Exchange Act, assuming the Corporation is a “non-accelerated filer” in accordance with the Exchange Act.

14. Record Holders. The Corporation and the transfer agent for the Series A Preferred Stock may deem and treat the record holder of any Series A Preferred Stock as the true and lawful owner thereof for all purposes, and neither the Corporation nor the transfer agent shall be affected by any notice to the contrary.
