Entry into a Material Definitive Agreement; Material ---------------------------------------------------- Modification to Rights of Security Holders. ------------------------------------------- On November 12, 2007, Ameron International Corporation ("Ameron" or the "Company") issued a press release announcing it had entered into a Shareholder Rights Agreement (the "Rights Agreement"). The Rights Agreement is designed to deter the use of coercive or abusive takeover tactics by one or more parties interested in acquiring Ameron or a significant position in Ameron common stock, as well as to generally assist the Board in representing the interests of all shareholders in connection with takeover proposals. The Rights Agreement accomplishes these objectives by encouraging a potential acquiror to negotiate with the Board. The Rights Agreement was not adopted in response to any effort to acquire control of Ameron; rather, it replaces a similar shareholder rights agreement which expired by its terms on December 16, 2006. One "Right" will be issued for each share of Ameron common stock outstanding as of November 16, 2007. Once exercisable, each Right will represent the right to purchase a unit consisting of 1/100th of a share of Ameron's preferred stock at a per unit price of $150, subject to adjustment as set forth in the Rights Agreement. The Rights will not become exercisable, and separate Rights Certificates will not be issued, unless the Rights are triggered. The Rights would be triggered by, among other things, a person or group acquiring or announcing an intention to acquire 20% or more of Ameron's voting stock, or upon the consummation of a transaction in which Ameron is not the surviving entity, the outstanding shares of Ameron common stock are exchanged for stock or assets of another person, or 50% or more of Ameron's consolidated assets or earning power are sold. However, the Rights Agreement would not be triggered by an all cash, fully financed cash offer for 100% of the outstanding shares of Ameron common stock at an offer price per share which represents a reasonable premium over the market price of Ameron common stock for the 30 trading days immediately preceding the date on which the offer is commenced. The Rights will expire on November 11, 2008, unless extended by Ameron's shareholders, in which case, the Rights will expire on November 11, 2010. Subject to certain exceptions, the Rights are redeemable by action of Ameron's Board of Directors at a nominal price per Right. The Company has filed a Registration Statement on Form 8-A (the "Form 8-A") with the U.S. Securities and Exchange Commission that contains additional information regarding the terms and conditions of the Rights Agreement, the Rights and the preferred stock. A copy of the Rights Agreement has been filed with the Securities and Exchange Commission as Exhibit 1 to the Form 8-A and is incorporated herein by reference. A copy of the press release is attached hereto as Exhibit 99.1. The foregoing summary description of the Rights Agreement, the Rights and the preferred stock does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which is incorporated herein by reference.
