Item 5.03.    Amendments to Articles of Incorporation or Bylaws

        The Company filed its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware on August 22, 2005, which became effective today. The Amended and Restated Certificate of Incorporation was duly approved and adopted by the Company's board of directors and stockholders on July 29, 2005. The Company's Amended and Restated Bylaws were approved and adopted by the board of directors and stockholders on July 29, 2005 and became effective today.

        Provisions of the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws include:

        Classified Board of Directors: The Company's amended and restated certificate of incorporation provides that its board of directors is divided into three classes of directors, with the classes to be as nearly equal in number as possible. The members of each class serve for a three-year term. As a result, approximately one-third of the Company's board of directors will be elected each year.

        Removal of Directors, Vacancies: The Company's amended and restated certificate of incorporation and its amended and restated bylaws provide that directors may be removed only for cause and only upon the affirmative vote of holders of at least a majority in voting power of all of the Company's shares that are entitled to vote generally in the election of directors, voting as a single class; provided, however, if at any time Kohlberg Kravis Roberts & Co. L.P. ("KKR") and DLJ Merchant Banking Partners III, L.P. ("DLJMB") no longer beneficially own at least a majority in voting power of all shares entitled to vote in the election of directors, then, any director may be removed only for cause by the affirmative vote of at least 80% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. In addition, the Company's amended and restated certificate of incorporation and its amended and restated bylaws provide that any vacancies on its board of directors will be filled only by the affirmative vote of a majority of the remaining directors, although less than a quorum.

        No Stockholder Action by Written Consent: The Company's amended and restated certificate of incorporation precludes stockholder action by written consent after the date on which KKR and DLJMB cease to beneficially own, in the aggregate, a majority of the voting power of all outstanding shares of its stock entitled to vote generally in the election of directors.

        Calling of Special Meetings of Stockholders: The Company's amended and restated bylaws provide that special meetings of its stockholders may be called only by its board of directors, its chief executive officer or the chairman of its board of directors.

        Advance Notice Requirements for Stockholder Proposals and Director Nominations: The Company's amended and restated bylaws provide that stockholders seeking to bring business before an annual meeting of stockholders or nominate candidates for election as directors must provide timely notice of their proposal in writing to the corporate secretary. Generally, to be timely, a stockholder's notice must be received at its principal executive offices not less than 90 nor more than 120 days prior to the first anniversary of the previous year's annual meeting. The Company's amended and restated bylaws also specify requirements as to the form and content of a stockholder's notice.

        Supermajority Provisions: The Company's amended and restated certificate of incorporation provides that the amended and restated bylaws may be amended only by a vote of at least 80% of the voting power of all of the outstanding shares of its stock entitled to vote in the election of directors, voting together as a single class. In addition, a vote of at least 80% of the voting power of all of the outstanding shares of the Company's stock entitled to vote in the election of directors, voting as a single class, is required to amend certain provisions of its certificate of incorporation relating to actions by stockholders by written consent, board membership, limited liability of directors and indemnification
