		•    Conference call and Webcast to be held at 9:30 a.m. today
		Montreal, November 1, 2004 — (NYSE: CGT; TSX: CAE) — CAE today announced it has signed a purchase and sale agreement with L-3 Communications Corporation (NYSE: LLL) to sell its Marine Controls unit for approximately C$328 million, including C$276 (US$225) million in cash and the assumption of C$52 (£23) million of project finance debt. The transaction is subject to certain regulatory approvals and other closing conditions, with closing expected prior to CAE’s current fiscal year end, March 31, 2005.
		CAE’s president and chief executive officer, Robert E. Brown, stated, “This decision marks an important first step in our strategic process by sharpening CAE’s focus on its core competency — the development and use of simulation and modeling technology to provide training solutions. The sale of Marine Controls will significantly improve our balance sheet and provide greater flexibility to the company.”
		“Under L-3’s ownership, the Marine Controls unit will have the opportunity to work alongside other marine-oriented businesses in L-3’s group,” added Mr. Brown. “I am confident that L-3 will welcome the addition of the Marine Controls unit and its capable people, and I would like to thank the employees for their contribution to CAE.”
		Marine Controls’ revenue for the fiscal year ending March 31, 2004 was C$158.6 million, representing approximately 15% of the company’s total revenue. The sale of the business unit is initially expected to have some dilutive impact on CAE’s earnings. Marine Controls employs approximately 460 individuals worldwide, primarily in Canada, the U.S., the U.K., Norway and India. When the transaction closes, it is expected to result in an after-tax capital gain of approximately C$125 million for CAE. Proceeds will initially be used primarily for the reduction of the company’s long-term debt. CAE retained Goldman, Sachs & Co. as its advisor on the transaction.
		Headquartered in New York City, L-3 Communications is a leading merchant supplier of Intelligence, Surveillance and Reconnaissance (ISR) systems and products, secure communications systems and products, avionics and ocean products, training devices and services, microwave components and telemetry, instrumentation, space and navigation products.
		CAE is a leading provider of simulation and modeling technologies and integrated training services for commercial and business aviation, and defence customers worldwide. The company has annual revenues of approximately C$1 billion, with operations and training facilities in 17 countries on five continents.
