(“Ideation” or the “Company”) (NYSE Amex: IDI, IDI.U, IDI.WS) today announced that its special meeting of stockholders to approve a business combination with SearchMedia International Limited (“SearchMedia”) will be held on October 26, 2009 at 8:30 am Eastern Time at the offices of Akerman Senterfitt, at One S.E.

At the special meeting, stockholders of Ideation will be asked to vote on the following ten proposals: (1) to approve an amendment to Section D of Article Sixth of Ideation’s Certificate of Incorporation to provide conversion rights to holders of shares issued in Ideation’s initial public offering upon approval of the business combination regardless of whether such holder votes for or against the business combination; (2) to approve the corporate redomestication of Ideation that will result in holders of Ideation securities holding securities in a Cayman Islands exempted company rather than a Delaware corporation; (3) to approve the business combination between ID Cayman and SM Cayman; (4) to approve the authorization in ID Cayman’s Memorandum of Association of 1,000,000,000 ordinary shares, as compared to 50,000,000 shares of common stock currently authorized in Ideation’s amended and restated certificate of incorporation, dated November 21, 2007, which we refer to as Ideation’s Certificate of Incorporation, and 10,000,000 preferred shares, as compared to 1,000,000 shares of preferred stock currently authorized under Ideation’s Certificate of Incorporation; (5) to approve in ID Cayman’s Articles of Association the elimination of the classified board currently authorized in Ideation’s Certificate of Incorporation; (6) to approve in ID Cayman’s Articles of Association a provision providing that the amendment of either of ID Cayman’s Memorandum of Association or Articles of Association will require a vote of two-thirds of its shareholders voting in person or by proxy at a meeting, as compared to the vote of a majority of the outstanding stock as set forth in Ideation’s Certificate of Incorporation; (7) to approve in ID Cayman’s Articles of Association a provision providing that the ID Cayman shareholders may pass resolutions without holding a meeting only if such resolutions are passed by a unanimous written resolution signed by all of the shareholders entitled to vote, as opposed to the provisions in Ideation’s Certificate of Incorporation that provide that stockholders may take action without a meeting if written consent to the action is signed by the holders of outstanding stock having the minimum number of votes necessary to authorize or take the action at a meeting of the stockholders; (8) to approve in ID Cayman’s Memorandum of Association a provision providing for the perpetual existence of the company, as compared to a provision providing for the termination of the company’s existence on November 19, 2009 as set forth in Ideation’s Certificate of Incorporation; (9) to approve the assumption of the SearchMedia International Limited 2008 Share Incentive Plan and its amendment and restatement as the Amended and Restated SearchMedia Holdings Limited Share Incentive Plan; and (10) to approve an adjournment or postponement of the special meeting for the purpose of soliciting additional proxies.
