BARINGTON GROUP ANNOUNCES PROXY CONTEST TO ELECT

A STOCKHOLDER REPRESENTATIVE TO THE BOARD OF DIRECTORS

OF AMERON INTERNATIONAL CORPORATION

New York, NY, February 28, 2011 – The Barington Group announced today that it has filed a definitive proxy statement with the Securities and Exchange Commission in connection with its solicitation of proxies to elect James A. Mitarotonda to the Board of Directors of Ameron International Corporation (NYSE: AMN) at the Company’s 2011 Annual Meeting.  The Annual Meeting is scheduled to be held at 10:00 a.m. (local time) on Wednesday, March 30, 2011 in Pasadena, California.  The Barington Group’s proxy statement and an accompanying WHITE proxy card are expected to be mailed to stockholders on or about March 1, 2011.

The Barington Group believes that the Company has a vast value potential that is not being realized and is convinced that if the Company were more effectively managed, its stock could be worth more than $100 a share.  The Barington Group also lacks confidence in the commitment of the Ameron Board to protect stockholder interests based on the Board’s track record in the area of CEO compensation, corporate governance and related party transactions.  

James A. Mitarotonda, the Barington Group’s highly qualified director nominee, is committed to improving shareholder value and protecting the interests of all stockholders of the Company.  If elected, Mr. Mitarotonda intends to work constructively with the other members of Ameron’s seven-member Board to seek to improve the Company’s operations, profitability and corporate governance.

Mr. Mitarotonda, 56, is the Chairman, President and Chief Executive Officer of Barington Capital Group, L.P.  Barington and its principals have substantial experience helping improve shareholder value and corporate governance as long-term investors in undervalued publicly-traded companies.  Mr. Mitarotonda is an experienced director who has represented stockholder interests on the boards of ten publicly-traded companies.  He currently serves as a director of Griffon Corporation, A. Schulman, Inc., The Pep Boys – Manny, Moe & Jack and Gerber Scientific, Inc. If elected at the Annual Meeting, Mr. Mitarotonda would resign from the board of one of these companies to ensure that he has ample time to dedicate to the affairs of Ameron.

A copy of the Barington Group’s proxy statement and its other solicitation materials can be found at the Barington Group’s web site located at www.ourmaterials.com/ameron.
