    Holders of Series C Preferred Stock are entitled to receive dividends on shares of Series C Preferred Stock (on an as-if-converted-to-Common-Stock basis, without regard to the Beneficial Ownership Limitation (as defined in the Series C Certificate of Designation), equal to and in the same form, and in the same manner, as dividends (other than dividends on shares of the Common Stock payable in the form of Common Stock) actually paid on shares of the Common Stock when, as if such dividends (other than dividends payable in the form of Common Stock) are paid on the shares of the Common Stock. In addition, holders of Series C Preferred Stock shall be entitled to receive, and the Company shall pay, payment-in-kind dividends on each share of Series C Preferred Stock, accruing at a rate equal to five percent (5.0%) per annum payable in shares of Series C Preferred Stock on the date that is 180 days after the date of the original issuance of such Series C Preferred Stock or such earlier date that that such holder may convert any portion of the Series C Preferred Stock to Common Stock.

     

    Except as otherwise required by law, the Series C Preferred Stock does not have voting rights. However, as long as any shares of Series C Preferred Stock are outstanding, the Company will not, without the affirmative vote of the holders of a majority of the then-outstanding shares of the Series C Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series C Preferred Stock or alter or amend the Series C Certificate of Designation, amend or repeal any provision of, or add any provision to, the Company’s third amended and restated certificate of incorporation, as amended (the “Charter”) or Second Amended and Restated Bylaws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of Preferred Stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series C Preferred Stock, regardless of whether any of the foregoing actions shall be by means of amendment to the Charter or by merger, consolidation, recapitalization, reclassification, conversion or otherwise, (ii) issue further shares of Series C Preferred Stock, or increase or decrease (other than by conversion) the number of authorized shares of Series C Preferred Stock (iii) prior to the Stockholder Approval (as defined in the Series C Certificate of Designation) or at any time while at least 30% of the originally issued Series C Preferred Stock remains issued and outstanding, consummate either: (A) any Fundamental Transaction (as defined in the Series C Certificate of Designation) or (B) any merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the stockholders of the Company immediately before such transaction do not hold at least a majority of the capital stock of the Company immediately after such transaction, or (iv) enter into any agreement with respect to any of the foregoing.

     

     

     

     

    The Series C Preferred Stock shall rank on parity with the Common Stock as to distributions of assets upon liquidation, dissolution or winding-up of the Company, whether voluntarily or involuntarily.
