If, prior to the Change of Control Conversion Date (as defined below), the Issuer has provided notice of its election to redeem some or all of the Series A Preferred Stock (whether pursuant to its optional redemption right or this special optional redemption right), the holders of Series A Preferred Stock will not have the conversion right described below under “Conversion rights” with respect to the shares of Series A Preferred Stock called for redemption.
Change of Control: Deemed to occur when, after the original issuance of the Series A Preferred Stock, the following have occurred and are continuing: (i) the acquisition by any person, including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of the Issuer's stock entitling that person to exercise more than 50% of the total voting power of all the Issuer's stock entitled to vote generally in the election of the Issuer's directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition); and (ii) following the closing of any transaction referred to in clause (i) above, neither the Issuer nor the acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the “NYSE”), the NYSE Amex Equities (the “NYSE Amex”) or The NASDAQ Stock Market (“Nasdaq”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or Nasdaq.
Conversion rights: Upon the occurrence of a Change of Control, provided that the Common Stock Authorization has occurred at or prior to such Change of Control, each holder of Series A Preferred Stock will have the right (subject to the special optional redemption described above) to convert some or all of the Series A Preferred Stock held by such holder on the Change of Control Conversion Date into a number of shares of the Issuer's common stock per share of Series A Preferred Stock to be converted equal to the lesser of:
l      the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference per share of the Series A Preferred Stock plus the amount of any accumulated and unpaid dividends thereon to, but not including, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a dividend record date and prior to the corresponding dividend payment date for the Series A Preferred Stock, in which case no additional amount for such accrued and unpaid dividends will be included in this sum) by (ii) the Common Stock Price (as defined below); and
l      1.7100 (the “Share Cap”), subject to adjustments to the Share Cap for any splits, subdivisions or combinations of our common stock.
The “Common Stock Authorization” consists of (1) the approval of an amendment by the Issuer's stockholders at the 2012 Annual Meeting, or any other amendment to the Issuer's amended and restated certificate of incorporation to increase the number of the Issuer's authorized shares of common stock by an amount in excess of the Exchange Cap (as defined below), whether at the Issuer's 2012 Annual Meeting or otherwise, and (2) the subsequent filing of such amendment to effect the increased number of authorized common shares provided for in such amendment.
The “Common Stock Price” is (i) if the consideration to be received in the Change of Control by the holders of the Issuer's common stock is solely cash, the amount of cash consideration per share of the Issuer's common stock or (ii) if the consideration to be received in the Change of Control by holders of the Issuer's common stock is other than solely cash (x) the average of the closing sale prices per share of the Issuer's common stock (or, if no closing sale price is reported, the average of the closing bid and ask prices per share or, if more than one in either case, the average of the average closing bid and the average closing ask prices per share) for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred as reported on the principal U.S. securities exchange on which the Issuer's common stock is then traded, or (y) the average of the last quoted bid prices for the Issuer's common stock in the over-the-counter market as reported by Pink OTC Markets Inc. or similar organization for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred, if the Issuer's common stock is not then listed for trading on a U.S. securities exchange.
The “Change of Control Conversion Date” is the date the Series A Preferred Stock is to be converted, which will be a business day selected by the Issuer that is no fewer than 20 days nor more than 35 days after the date on which the Issuer provides the required notice of the occurrence of a Change of Control to the holders of Series A Preferred Stock.
The “Exchange Cap” is the aggregate number of shares of the Issuer's common stock (or equivalent alternative conversion consideration, as applicable) issuable or deliverable, as applicable, in connection with the exercise of the Change of Control Conversion Right. For the avoidance of doubt, subject to certain adjustments, the Exchange Cap will not exceed 10,260,000 shares of the Issuer's common stock (or equivalent alternative conversion consideration, as applicable), subject to proportionate increase to the extent the underwriters' over-allotment option to purchase additional shares of Series A Preferred Stock is exercised, not to exceed 11,799,000 shares of the Issuer's common stock in total (or equivalent cash, securities or other property or assets (including any combination thereof), as applicable).
