BURBANK, CA, March 26, 1998--Iwerks Entertainment, Inc. (NMS:IWRK) said today that it continues to support its proposed merger with Showscan Entertainment Inc. (NMS:SHOW), and urged shareholders to vote their proxy ballots in favor of the merger. The company said that while it was disappointed by today's announcement by one of its shareholders, Heartland Advisors Inc., that Heartland would oppose the transaction, it is continuing to meet with and contact shareholders to explain the benefits of the merger. Iwerks said that it stands behind its previously stated position that "this merger is strategically significant to Iwerks and that the benefits are considerable." In presentations to shareholders this week, Iwerks' management has presented in significant detail its integration plan and business strategy, as well as financial projections that illustrate the positive effect the merger would have on the value of its stock. The company cited a report issued Wednesday by Institutional Shareholders Services (ISS) a leading proxy analysis firm, that said the merger warrants shareholder support. "ISS's objectivity in this case is significant. They listened, as have we, to the concerns of certain shareholders who have publicly stated their opposition to this transaction, then they listened to our detailed presentation of the facts and our plans for the future of Iwerks. In the end, they recommended that our shareholders support the merger." Both Iwerks' and Showscan's Board of Directors have unanimously approved the merger and recommend that shareholders vote in favor of it. Iwerks' shareholder meeting to vote on the proposed merger and other matters will be held at 10:00 a.m. local time on March 31, 1998 at Iwerks' offices, 4540 West Valerio Street, Burbank, California.
