The combined company, which will bring together the two largest motion simulation companies, will be the largest provider of ride simulation entertainment attractions and software in the world. The transaction calls for each share of Showscan common stock to be converted into 0.85 of a share of Iwerks common stock. Outstanding Showscan convertible preferred stock will be exchanged for Iwerks common stock at the 0.85 ratio on an as converted basis. Iwerks expects to issue approximately 5.62 million shares of Iwerks common stock in the merger (plus shares issuable upon exercise of outstanding Showscan options and convertible notes), resulting in an estimated transaction value of approximately $27.4 million (based upon a closing price of Iwerks common stock on the Nasdaq National Market on August 4, 1997 of $4.875 per share). The transaction will be accounted for as a pooling of interests, after which Showscan will become a wholly owned subsidiary of Iwerks. Completion of the merger is subject to stockholder approval, as well as other customary closing conditions. The transaction is expected to close in the fourth calendar quarter of this year. As a result of the merger, the combined company will have: - Over 160 simulation theaters, which is the largest installed base of simulation theaters in the world; - Pro forma recurring film licensing revenues of approximately $12 million, based on Iwerks' and Showscan's fiscal 1997 results; - An expanded presence in the important Asian market, where Showscan has a strong installed base of 26 theaters; - Distribution rights to an industry-leading library of more than 60 ride simulation titles, including the critically-acclaimed DEVIL'S MINE RIDE and COSMIC PINBALL from the Showscan 28 title library and DINO ISLAND and SECRETS OF THE LOST TEMPLE from the Iwerks 40 title library; and - Showscan's interests in owned-and-operated attractions in Los Angeles at Universal City Walk and in London at the Trocadero, among others. Roy A. Wright, Iwerks' Chairman and Chief Executive Officer, will be Chairman and Chief Executive Officer of the combined company. Wright said, "This significant strategic move creates a company that is the strong leader in the ride simulation market. The creative and technical skills of the combined company will help us better serve and support our existing networks via premium software and technical innovation, while strengthening our marketing and sales effort to continue the growth of the market overall. "This merger also provides the combined company significant opportunities to realize efficiencies and synergies available by operating with a combined corporate overhead. We expect to realize significant cost savings in the combination, particularly in the areas of general and administrative expenses as well as marketing and selling expenses." Dennis Pope, President and Chief Executive Officer of Showscan, said, "This transaction allows Showscan stockholders to be part of the largest motion simulation entertainment company in the world. It is another step in bringing the remarkable promise of simulation entertainment to fruition. "The combined company will be the strongest, broadest and most versatile player in the industry. Existing and potential customers of both companies will win because they will not have access to the broadest selection of software and technology options, as well as the exemplary service and support the combined company will provide."
