Under the terms of the Merger Agreement, Merger Sub will be merged with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as an indirectly wholly owned subsidiary of the Reporting Person (the “Surviving Corporation”). At the effective time of the Merger, shares of Common Stock owned by the Reporting Person or Merger Sub and shares of Common Stock held by the Issuer (as treasury stock or otherwise) will be canceled. All other outstanding shares of Common Stock, other than shares of Common Stock owned by any stockholder who is entitled to and who properly exercises appraisal rights under Delaware law, will be canceled and each converted into the right to receive $6.35 in cash, without interest, less any applicable withholding taxes. Shares of the Series C Junior Participating Convertible Preferred Stock, par value $0.001 per share of the Issuer (the “Series C Preferred Stock”) will be canceled and each converted into the right to receive $4703.7037037 in cash, without interest, less any applicable withholding taxes. Warrants to acquire Company Stock (“Warrants”) will be canceled and each Warrant shall be converted into the right to receive, with respect to each share of Common Stock subject to such Warrant, an amount in cash equal to $6.35 minus the applicable exercise price per share of Common Stock, without interest, less any applicable withholding taxes. Consummation of the Merger is not subject to a financing condition, but it is subject to certain customary conditions, including adoption of the Merger Agreement by the Issuer’s stockholders and the expiration or termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and certain foreign antitrust laws. The description of the Merger Agreement included in this Item 4 is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is incorporated herein by reference under Exhibit 1 hereto. In connection with the Merger Agreement, certain stockholders of the Issuer (the “Stockholders”) entered into a Voting Agreement (the “Voting Agreement”) with the Reporting Person. Pursuant to the Voting Agreement and as more fully described therein, each Stockholder, among other things, (a) agreed to vote all its shares of Common Stock and all its shares of the Series C Preferred Stock (i) in favor of the Merger, including the adoption of the Merger Agreement, all other transactions contemplated by the Merger Agreement and any other matters that must be approved by the stockholders of the Issuer in order for the transactions contemplated by the Merger Agreement to be consummated and (ii) against any and all alternative proposals; (b) agreed it shall not, and shall cause its representatives not to, directly or indirectly solicit, initiate, knowingly encourage or facilitate or take certain other actions with respect to, any alternative proposals; (iii) agreed to convert a portion of its shares of Series C Preferred Stock into shares of Common Stock (provided that the number of shares of Common Stock issuable pursuant to such conversion shall not exceed such number of shares of Common Stock, the issuance of which would require approval by the stockholders of the Company under the applicable rules of the NASDAQ Stock Market), and (iv) agreed to certain transfer restrictions with respect to its shares of Common Stock, shares of Series C Preferred Stock and Warrants (the aggregate shares of Common Stock held by the Stockholders, including those issuable upon the conversion of the Series C Preferred Stock and the exercise of the Warrants, the “Subject Shares”). If either the Issuer or the Reporting Person terminates the Merger Agreement in accordance with its terms before the Merger is completed, the Voting Agreement will also terminate.
