question and answer session, contain certain forward-looking statements and 
information, which reflect the current view of MacDonald, Dettwiler and

by the use of forward-looking terminology such as "may", "will", "would", 
"could", "should", "expect", "intend", "estimate", "anticipate", "plan", 
"foresee", "believe" or "continue" or the negatives of such terms or

are based on MDA's current expectations, estimates, projections and 
assumptions made in light of its experience and perception of historical 
trends. Forward-looking statements are subject to risks and uncertainties, 
many of which are beyond MDA's control and the effects of which can be

reputation; quality issues and failure of systems to meet performance 
requirements; failure of the Company to manage its acquisitions and breaches 
of contracts and indemnities and related risks on divestitures; satellite

threats; detrimental reliance on third parties for data; dependence on key 
employees, potential for work stoppages and lack of oversight over a U.S. 
proxy board and management; failure to anticipate changes in technology, 
technical standards and offerings or comply with the requisite standards; 
failure to maintain technological advances and market positions; significant

or subcontractors to effect technology transfer; changes in customer security 
requirements and the resulting cancellation of contracts; failure to maintain 
business alliances; uncertainty in financing arrangements; failure of 
counterparties in financing arrangements and financial derivative contracts;
