-------------------------------------------------------------------------------- AN IMPORTANT MESSAGE FOR NET PERCEPTIONS STOCKHOLDERS o APPROVAL OF MANAGEMENT'S PROPOSED LIQUIDATION COULD JEOPARDIZE YOUR ABILITY TO RECEIVE THE FULL VALUE OF YOUR INVESTMENT o YOU, THE STOCKHOLDERS, SHOULD HAVE THE RIGHT TO CHOOSE THE BEST WAY TO RECEIVE FULL VALUE FOR YOUR INVESTMENT! o DO NOT RETURN MANAGEMENT'S WHITE PROXY CARD FOR ANY REASON, EVEN AS A PROTEST! o WAIT UNTIL YOU HAVE RECEIVED OUR PROXY STATEMENT AND BLUE PROXY CARD BEFORE MAKING ANY VOTING DECISIONS -------------------------------------------------------------------------------- February 27, 2004 Dear Net Perceptions, Inc. Stockholder: As you may know, the Net Perceptions Board of Directors and management are seeking your support for their proposed plan of liquidation at the upcoming Special Meeting of Stockholders currently scheduled for March 12, 2004. The approval of that plan will effectively terminate your company's existence and eliminate your ability to receive anything more for your stock than the conditional payment described in management's proxy statement. We, Obsidian Enterprises, Inc., believe that management's conditional, estimated payout, $0.45 per share in the very best case, does not represent the full value of your investment. As an alternative, Obsidian has offered to exchange 1/25 share of Obsidian common stock for each Net Perceptions share. You should also consider 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. That's not just us telling you that. Net Perceptions' Board and management say the same thing in their February 12 proxy materials! We will shortly be mailing you our definitive proxy materials that will contain more detailed information and a BLUE proxy card. Until you receive that information, we strongly urge you not to return any white proxy card sent to you by Net Perceptions' management. 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. 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.
