ELECTION AND RATIFICATION OF APPOINTMENT OF DIRECTORS
Our Board is divided into three classes serving staggered three-year terms. Our Certificate of Incorporation requires us to ensure each class is as nearly equal in number as possible. Directors for each class are elected at the Annual Meeting of Stockholders held in the year in which the term for their class expires.
The terms for two Directors will expire at this 2007 Annual Meeting. Directors elected at the 2007 Annual Meeting will hold office for a three-year term expiring at our 2010 Annual Meeting (or until their respective successors are elected and qualified, or until their earlier death, resignation or removal). At our 2005 Annual Meeting, Dr. Grieve was elected to a three year term scheduled to expire at our 2008 Annual Meeting. On May 12, 2006, our Board appointed Dr. Grieve to a term scheduled to expire at our 2009 Annual Meeting. We previously had only one Director in the class with term set to expire at our 2009 Annual Meeting as both Dr. Nova and Dr. Stevenson decided not to stand for re-election at our 2006 Annual Meeting. Our Certificate of Incorporation requires us to have at least two Directors in each class if our Board consists of six or seven Directors. If ratified, Dr. Grieve will hold office for a term expiring at our 2009 Annual Meeting (or until his successor is elected and qualified or until his earlier death, resignation or removal). Votes cannot be cast and proxies cannot be voted other than for the two nominees and the appointee named below. Both of the nominees and the appointee are currently Directors of Heska. There are no family relationships among Heskas Executive Officers and Directors.
