If this statement is filed pursuant to Rule 13d-1(c), check this box. [X] 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: From April 4, 2007 to April 13, 2007, Portside Growth and Opportunity Fund had an option to purchase up to $200,000,000 aggregate principal amount of Variable Rate Senior Convertible Notes due 2013 ("Notes"), which would have been convertible into approximately 1,508,352 Units. On April 12, 2007, Portside Growth and Opportunity Fund exercised a portion of this option to purchase $150,000,000 principal amount of Notes, convertible into approximately 1,131,264 Units, leaving Portside Growth and Opportunity Fund with an option to purchase $50,000,000 aggregate principal amount of Notes expiring on April 25, 2007. Therefore, as of the date of this filing, each Reporting Person may be deemed the beneficial owner of $100,000,000 principal amount of Notes,

CUSIP No. 029169109 13G Page 11 of 15 Pages convertible into approximately 754,176 Units and an option to purchase up to $50,000,000 aggregate principal amount of Notes, convertible into approximately 377,088 Units. On April 4, 2007, Highbridge International LLC purchased the same principal amount of Notes and received the same options as are held by the Reporting Persons. The Reporting Persons do not affirm that a group has been formed, but this disclosure is being made to ensure compliance with the Securities Exchange Act of 1934 (the "Act"). Based on information and belief, Highbridge International LLC and its affiliates (the "Highbridge Entities") are filing a Schedule 13G reporting ownership of $100,000,000 principal amount of Notes, convertible into approximately 754,176 Units and the option to purchase up to $50,000,000 principal amount of Notes, convertible into 377,088 Units. The Reporting Persons expressly disclaim beneficial ownership of securities held by any person or entity other than the various entities and accounts under the Reporting Persons' management and control. The securities reported herein as being beneficially owned by the Reporting Persons do not include any securities held by the Highbridge Entities (including but not limited to accounts or entities under its control) or any other person or entity other than the various entities and accounts under the Reporting Persons' management and control. Ramius Capital Group, L.L.C., a Delaware limited liability company ("Ramius") is the investment advisor of Portside Growth and Opportunity Fund and has the power to direct some of the affairs of Portside Growth and Opportunity Fund, including decisions respecting the disposition of the proceeds from the sale of shares of the Units. C4S & Co., L.L.C., a Delaware limited liability company, is the managing member of Ramius and in that capacity directs its operations. Peter A. Cohen, Morgan B. Stark, Thomas W. Strauss and Jeffrey M. Solomon are the managing members of C4S & Co., L.L.C. and in that capacity direct its operations. The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of Units owned by another Reporting Person. In addition, each Reporting Person disclaims beneficial ownership of Units not owned by such Reporting Person. (b) Percent of class: The Company's Annual Report on Form 10-K that was filed on March 6, 2007 and amended on March 16, 2007, indicates that there were 61,856,830 Units outstanding as of March 1, 2007. Therefore, based on the Company's outstanding Units and the Units issuable upon the conversion of the Notes issued by the Company, as of the date of this filing, each Reporting Person may be deemed to beneficially own 1.80% of the outstanding Units of the Company. During the period from April 4, 2007 to April 13, 2007, each Reporting Person may have been deemed to beneficially own 3.53% of the outstanding Units of the Company. The foregoing does not include the similar percentage of Units that the Highbridge Entities may be deemed to beneficially own. The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of shares of Units owned by another Reporting Person or by any of the Highbridge Entities.
