Conversion Limitations. The Corporation shall not effect any conversion of any shares of Series D Preferred Stock, and a Holder shall not have the right to effect any such conversion of any of his, her or its shares of Series D Preferred Stock, pursuant to Section 5 or otherwise, to the extent that after giving effect to such conversion, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons “Attribution Parties”)), would beneficially own voting stock in excess of the Beneficial Ownership Limitation (as defined below). For purposes of this Section 5.3.7, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon any conversion with respect to which a Notice of Conversion has been given, but shall exclude the number of shares of Common Stock which would be issuable upon # conversion of the remaining, unconverted shares of Series D Preferred Stock beneficially owned by the Holder or any of its Affiliates or Attribution Parties and # exercise or conversion of the unexercised or nonconverted portion of any other derivative securities of the Corporation subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 5.3.7 applies, the determination of the number of shares of Series D Preferred Stock that are convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination as to the number of shares of Series D Preferred Stock that are convertible, in each case subject to the Beneficial Ownership Limitation, and the Corporation shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The “Beneficial Ownership Limitation” shall be 9.99% of the Cumulative Voting Power outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon the conversion specified in the Notice of Conversion. For purposes of this Section 5.3.7, the “Cumulative Voting Power” shall be the sum of the votes that may be cast at a meeting of the Corporation’s shareholders by the record holders of securities issued by the Corporation which by their terms provide the holder of such securities the right to cast votes on any proposal presented for vote of the shareholders. For purposes of this Section 5.3.7, in determining the Cumulative Voting Power, a Holder may rely on the information pertaining to the Cumulative Voting Power reflected in # the Corporation’s most recent periodic or annual report filed with the Securities and Exchange Commission, as the case may be, # a more recent public announcement by the Corporation or # a more recent written notice by the Corporation or its transfer agent setting forth the number of shares of Common Stock and/or the number of shares of other classes of stock with voting rights outstanding. Upon the written request of a Holder (which, for clarity, includes electronic mail), the Corporation shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock and number of shares of other classes of voting stock then outstanding. In any case, the Cumulative Voting Power shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including the Series D Preferred Stock, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock or such number of outstanding shares of other classes of voting stock, as applicable, was reported. The Holder, upon not less than 61 days’ prior notice to the Corporation, may increase the percentage of Cumulative Voting Power that defines the Beneficial Ownership Limitation to 19.99%.
