Compensation of Named Executive Officers

     The executive officers named in the summary compensation table in the proxy statement for Ixia’s 2006 Annual Meeting of Shareholders (the “Named Executive Officers”) have their base salaries determined annually by the Compensation Committee of the Board of Directors (the “Compensation Committee”). Such determinations ordinarily take place in the first quarter of each fiscal year and are effective as of January 1st (i.e., the first day of that fiscal year). The Named Executive Officers are all “at will” employees and do not have written or oral employment agreements with the Company. The Company, upon the approval of the Committee, retains the right to unilaterally decrease or increase such officers’ base salaries at any time during the fiscal year.

     The annual base salaries for the Named Executive Officers (effective since January 1, 2006) are as follows:
