Millennium Operations, L.L.C., a Delaware limited liability company ("Millennium Operations") is the managing member of Catapult Operations and consequently may be deemed to have voting control and investment discretion over securities deemed to be beneficially owned by Catapult Operations. Millennium International Management, L.P., a Delaware limited partnership ("Millennium International Management") is the managing member of Millennium Operations and consequently may be deemed to have voting control and investment discretion over securities deemed to be beneficially owned by Millennium Operations.

Israel A. Englander ("Mr. Englander") is the managing member of Millennium Management. As a result, Mr. Englander may be deemed to be the beneficial owner of any shares deemed to be beneficially owned by Millennium Management. The foregoing should not be construed in and of itself as an admission by Catapult Operations, Millennium Operations, Millennium International Management, Millennium International Management GP, Integrated Holding Group, Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco or Catapult Partners, as the case may be.

   The business address for Millenco, Millennium Operations, Millennium International Management, Millennium International Management GP, Integrated Holding Group, Millennium Management and Mr. Englander is c/o Millennium Management, L.L.C., 666 Fifth Avenue, New York, New York 10103. The business address for Catapult Partners and Catapult Operations is c/o Catapult Operations, L.L.C., 650 Fifth Avenue, 32nd Floor, New York, New York 10019. Mr. Englander is a United States citizen.

   Note:  Integrated Holding Group is a non-managing member of Millenco. As a non-managing member, Integrated Holding Group has no voting control or investment discretion over Millenco or its securities positions.

   (d)  During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

   (e)  On December 1, 2005, Millennium Management and Mr. Englander, together with Millennium Partners, L.P. ("Millennium Partners") and certain related persons and entities, entered into settlements with the Securities and Exchange Commission ("SEC") and the Attorney General of the State of New York (the "NYAG") relating to allegations that Millennium Partners had engaged in a pattern of deceptive "market timing" of mutual fund shares in years prior to 2004 and, in the case of the settlement with the NYAG only, had failed to take adequate steps to prevent a trader from engaging in mutual fund "late trading" in violation of firm policy. The parties neither admitted nor denied the allegations or findings (except as to jurisdiction) but consented to the entry of findings. The SEC proceedings are In the Matter of Millennium Partners, L.P., et al. Securities Act Release No. 8639 (December 1, 2005), available at www.sec.gov. Contemporaneously, the NYAG issued an Assurance of Discontinuance relating to the claims and findings of that office.

   Neither the Reporting Persons nor any other party admitted or denied any of the allegations or findings in these matters. The remedies included disgorgement by the entities of approximately $148 million of mutual fund trading profits, civil penalties aggregating approximately $32.15 million (with approximately $30 million being paid by Mr. Englander), an administrative order to cease and desist from violations of the antifraud provisions of the Securities Act of 1933 and the Securities Exchange Act of 1934 (the "Exchange Act"), and prophylactic relief.

Item 3.      Source and Amount of Funds or Other Consideration.

   The amount of funds used to purchase the warrants ("Warrants") owned by Millenco and the Common Stock and Warrants owned by Catapult Partners in the transactions giving rise to this Schedule 13D was approximately $657,700 and $570,200, respectively, calculated on an average cost basis (excluding brokerage commissions) by account. In some cases, the consideration attributable to the individual constituent parts of the Issuer’s units ("Units") (each Unit consisting of one share of Common Stock and two Warrants) is based on estimates by the Reporting Persons (e.g., this might be necessary in the case that, for example, Common Stock and Warrants were purchased as part of a Unit, and when the Unit’s constituent parts became separately traded, a Reporting Person sold such Common Stock and such retained Warrants needed to be valued.) Millenco and Catapult Partners effect purchases of securities primarily through margin accounts maintained for Millenco and Catapult Partners with prime brokers, which may extend margin credit to Millenco and Catapult Partners as and when required to open or carry positions in the margin accounts, subject to applicable Federal margin regulations, stock exchange rules and the prime broker’s credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.

Item 4.       Purpose of Transaction.

   The Reporting Persons are engaged in the investment business. In pursuing this business, the Reporting Persons analyze the operations, capital structure and markets of companies, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management). From time to time, one or more of the Reporting Persons may hold discussions with third parties or with management of such companies in which the Reporting Persons may suggest or take a position with respect to potential changes in the operations, management or capital structure of such companies as a means of enhancing shareholder value. Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act, including, without limitation, such matters as disposing of or selling all or a portion of the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting certain types of anti-takeover measures and restructuring the Issuer’s capitalization or dividend policy.

   The Reporting Persons employ the services of a number of portfolio managers, each of whom independently employs a separate and distinct trading strategy. A portion of the securities of the Issuer held by the Reporting Persons are held in accounts of the Reporting Persons managed by portfolio managers who engage in event-, risk- or merger-arbitrage or fundamental strategies.

   Except as set forth above, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions required to be described in Item 4 of Schedule 13D. Each of the Reporting Persons may, at any time, review or reconsider its position with respect to the Issuer and formulate plans or proposals with respect to any of such matters, but has no present intention of doing so.

Item 5.      Interest in Securities of the Issuer.

   (a)  As of the date hereof, (i) Millenco is the beneficial owner of 1,071,671 Warrants and (ii) Catapult Partners is the beneficial owner of 93,700 shares of Common Stock and 50,000 Warrants. Each Warrant, which became exerciseable upon the Issuer’s completion of a business combination on March 6, 2007, entitles the holder to purchase one share of the Issuer’s Common Stock at a price of $5.00 per share.

   Catapult Operations, as the investment manager of Catapult Partners, may be deemed to beneficially own securities owned by Catapult Partners. Millennium Operations, as the managing member of Catapult Operations, may be deemed to beneficially own securities deemed to be beneficially owned by Catapult Operations. Millennium International Management, as the managing member of Millennium Operations, may be deemed to beneficially own securities deemed to be beneficially owned by Millennium Operations. Millennium International Management GP, as the general partner of Millennium International Management, may be deemed to beneficially own securities deemed to be beneficially owned by Millennium International Management. Integrated Holding Group, as the sole shareholder of Catapult Partners, may be deemed to beneficially own securities owned by Catapult Partners. Millennium Management, as the manager of Millenco and the general partner of Integrated Holding Group, may be deemed to beneficially own securities beneficially owned by Millenco and deemed to be beneficially owned by Integrated Holding Group, respectively. Mr. Englander, as the managing member of Millennium Management, may be deemed to beneficially own any securities deemed to be beneficially owned by Millennium Management.

   (b)  Millenco may be deemed to hold the sole power to vote and to dispose of the 1,071,671 shares of Common Stock described in (a) above. Catapult Partners, Catapult Operations, Millennium Operations, Millennium International Management, Millennium International Management GP and Integrated Holding Group may be deemed to hold the sole power to vote and to dispose of the 143,700 shares of Common Stock described in (a) above. Mr. Englander and Millennium Management may be deemed to hold the sole power to vote and to dispose of the 1,215,371 shares of Common Stock described in (a) above, which represents approximately 8.1% of the outstanding shares of Common Stock. The calculation of the foregoing percentage is on the basis of 13,907,892 shares of the Issuer’s Common Stock outstanding as disclosed by the Issuer on its Form 8-K dated March 12, 2007.

   The foregoing should not be construed in and of itself as an admission by Catapult Operations, Millennium Operations, Millennium International Management, Millennium International Management GP, Integrated Holding Group, Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco or Catapult Partners, as the case may be.

   (c)  Transactions in Common Stock and Warrants during the past 60 days: Schedule A annexed hereto lists all transactions in the Common Stock and Warrants during the past 60 days by the Reporting Persons.

   (d)  No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of, dividends from, or proceeds from the sale of, the shares of Common Stock reported in this Statement.

Item 6.      Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

   Millenco maintains an open short position of 500 shares of Common Stock, which position is not netted against the data provided herein as to the number of shares beneficially owned by the Reporting Persons.

   In connection with arrangements with Millenco’s and Catapult Partners’ prime brokers, such prime brokers are permitted to lend securities in Millenco’s and Catapult Partners’ accounts to the extent permitted by debit balances in such account. Millenco and Catapult Partners generally will not have any knowledge of the specific loans made by such prime brokers. In addition, in the ordinary course of business, Millenco and Catapult Partners (or its prime brokers), may borrow securities to satisfy delivery obligations arising from short sales. Millenco may lend securities to third parties and such loans generally may be recalled upon demand.

   There are no other contracts, arrangements, understandings or relationships among the Reporting Persons, or between the Reporting Persons and any other person, with respect to the securities of the Issuer.
