For purposes of this Section 1, "Change of Control" means (i) the sale, lease or transfer, whether direct or indirect (other than by way of merger or consolidation), of all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, in one transaction or a series of related transactions, to any "person" or "group," (ii) the liquidation or dissolution of the Company or the adoption of a plan of liquidation or dissolution of the Company, (iii) the acquisition of "beneficial ownership" by any "person" or "group" of securities 2 of the Company which when aggregated with all other securities of the Company then owned by such person or group would permit such person or group to elect a majority of the directors of the Company or any successor entity (such securities entitled to so vote being referred to as "Voting Stock") by way of sale, transfer or issuance of, or a series of sales, transfers and/or issuances of, Voting Stock or otherwise, or (iv) any merger or consolidation to which the Company is a party, except for a merger or consolidation in which the holders of the Company's outstanding Voting Stock entitled to elect a majority of the members of the Company's Board of Directors immediately prior to the merger or consolidation shall continue to own directly or beneficially the outstanding Voting Stock of the surviving corporation entitled to elect a majority of the Board of Directors of the surviving corporation after giving effect to the merger or consolidation. For purposes of this Agreement, (i) the terms "person" and "group" shall have the meanings set forth in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), whether or not applicable, and (ii) the term "beneficial owner" shall have the meaning set forth in Rules 13d-3 and 13d-5 under the Exchange Act, whether or not applicable. Section 2. Transfer Restrictions. Each of the Stockholders hereby covenants and agrees, severally and not jointly, that, (i) during the term of this Agreement, with respect to the Debentures, and (ii) during a period of two years from the date hereof, with respect to the Conversion Shares, it will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of (any such act being referred to herein as a "transfer") any of the Debentures or Conversion Shares, other than (x) a transfer to any other Stockholder, (y) a transfer by a Stockholder to his or her spouse or lineal descendants, or any trust or other entity owned by or for the benefit of any such person, or (z) a transfer pursuant to a transaction that would constitute a Change of Control that is approved by the Board of Directors of the Company as provided in Section 1(b) above.
