Stockholder: As we have previously written, approval of management's proposed plan of liquidation at the March 12 Special Meeting will effectively terminate your company's existence. Consequently, approval will also eliminate your ability to receive anything more for your stock than the conditional, estimated payment of $0.45 per share, in the very best case, described in management's proxy statement. WE STRONGLY URGE YOU NOT TO RETURN ANY OF MANAGEMENT'S WHITE PROXY CARDS FOR ANY REASON. We will shortly be mailing you our proxy materials that will contain more detailed information. WAIT until you have received our detailed proxy materials and BLUE proxy card BEFORE making any voting decisions on the important matters to be considered at the Special Meeting. You should also consider that Net Perceptions' management has acknowledged that if the proposed plan of liquidation is approved and carried out, YOU MAY STILL BE LIABLE TO REPAY UP TO THE ENTIRE AMOUNT OF ANY PAYOUT, INCLUDING LAST FALL'S SPECIAL PAYOUT OF $1.50 PER SHARE, if management underestimates its liabilities, including those from the several lawsuits still pending against the company. IF YOU HAVE ANY QUESTIONS, PLEASE CALL OUR PROXY SOLICITOR, INNISFREE M&A INCORPORATED, TOLL-FREE, AT 1-888-750-5834. Sincerely, /s/ Timothy S. Durham --------------------- Timothy S.
