Dear Associates:

As a follow up to the memo dated April 17, 2006, all shareholders of IUSA stock either through our 401k Plan, our Payroll Stock Purchase Plan and/or individual stock purchase should have received the WHITE proxy voting card. If you haven’t done so already, we encourage you to make your vote count by signing and returning the proxy card or voting online at https://www.proxyvotenow.com/iusa or voting by phone at 866.818.3987. Don’t let your interests go unheard. Please vote today.

We strongly urge you to disregard the dissidents’ materials and the blue proxy card and vote FOR the incumbent infoUSA directors. Your Board of Directors also urges you to vote AGAINST shareholder proposal number 2.

If you have any questions, please feel free to call me and I will be happy to answer any questions you may have.

Thank you.
