Items 1.01 and 3.03.       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.
