On June 15, 2011, the Board of Directors of Omega Protein Corporation (the “Company”), promoted Gregory Toups, the Company’s Vice President and Controller, to the additional position of Chief Accounting Officer, a position previously held by Bret Scholtes who continues as the Company’s Executive Vice President and Chief Financial Officer. Mr. Toups has served as the Company’s Vice President and Controller since May 2008, as Controller since May 2005, and as Assistant Controller from March 2005 to May 2005. Prior thereto, Mr. Toups was employed by the accounting firms Kushner LaGraize LLC, from November 2001 to March 2005, and by PricewaterhouseCoopers, LLP, from January 1998 to November 2001. In connection with his promotion, Mr. Toups’ annual base salary was increased to $200,000 effective June 15, 2011.

Under the 2006 Long-Term Incentive Plan (the “Plan”) of the Company, on each date of the Company’s Annual Meeting of Stockholders, each Outside Director (as defined in the Plan) receives an automatic stock option grant under the Plan to purchase a number of shares of the Company’s common stock at fair market value on the date of the grant. The number of option shares is determined by the Board of Directors and is currently set at 10,000.

The Company’s 2011 Annual Meeting of Stockholders (the “2011 Stockholders’ Meeting”) was held on June 15, 2011. Accordingly, each Outside Director (Dr. Gary L. Allee, Gary R. Goodwin, Paul M. Kearns, Dr. William E. M. Lands, David A. Owen and Harry O. Nicodemus IV) received a stock option grant pursuant to the Plan for 10,000 shares of the Company’s common stock. These non-qualified stock options vest six months and one day after the date of the grant and have an exercise price of $13.41 per share, the fair market value of the Company’s common stock on the date of grant.

On June 15, 2011, the Board of Directors elected Joseph von Rosenberg III, the Company’s Chairman of the Board, Chief Executive Officer and President, as Chairman of the Scientific Committee of the Board of Directors.
