Item 4. Ownership.

   Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

   (a) Amount Beneficially Owned

   As of the date of this filing, each Reporting Person may be deemed to be the beneficial owner of 1,561,554 Warrants ("Warrants") owned by Millenco, L.L.C., a Delaware limited liability company ("Millenco"), formerly known as Millenco, L.P., a Delaware limited partnership. Each Warrant entitles the holder to purchase one share of the Company’s Common Stock at a price of $5.00. Each Warrant will become exercisable on the later of the Company’s completion of a business combination and August 15, 2006, and will expire on August 15, 2009, or earlier upon redemption. On January, 2, 2007, the Company announced that it had completed its acquisition of International Paper Company’s kraft papers business, thereby making the warrants exercisable as of such date.

   In addition, Millenco has an open short position of 505,200 shares of Common Stock, which position is not netted against the data provided herein for the purpose of determining the number of shares beneficially owned by the Reporting Persons.

   Millenco is a broker-dealer and a member of the American Stock Exchange and the NASDAQ.

   Millennium Management, L.L.C., a Delaware limited liability company ("Millennium Management"), is the manager of Millenco, and consequently may be deemed to have voting control and investment discretion over securities owned by Millenco. 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 Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco.

   Note: Integrated Holding Group, L.P., a Delaware limited partnership ("Integrated Holding Group"), is a non-managing member of Millenco. As a non-managing member, Integrated Holding Group has no investment or voting control over Millenco or its securities positions.

(b) Percent of Class
