Forward-looking statements generally can be identified 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 variations of them or similar terminology. The forward-looking statements in this press release 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 difficult to predict. MDA's actual results of operations could differ materially from historical results or current expectations.

With regard to MDA's proposed acquisition of SS/L, there can be no assurance that MDA will realize the anticipated benefits or results due to a variety of factors, including: inability to complete the acquisition in the timeframe anticipated or at all; inability to obtain governmental approvals of the transaction or satisfy other conditions to the transaction on the proposed terms and timeframe; the terms of the proposed transaction may need to be modified to obtain governmental approvals of the transaction or satisfy other conditions to the transaction; the ability to promptly and effectively integrate the businesses of MDA and SS/L; higher than anticipated integration costs; diversion of management time on acquisition-related issues; and failure to obtain the consent or other agreement of certain counterparties whose consent or agreement is required in order for MDA to acquire certain business relationships. The anticipated benefits from the proposed transaction may not be realized in the time frame anticipated or at all as a result of several factors including changes in general economic and market conditions, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which SS/L operates.

We caution that the preceding list of material risk factors is not exhaustive and other factors could also adversely affect MDA's results. You are referred to the risk factors described in MDA's most recent annual Management's Discussion and Analysis, Annual Information Form and other documents on file with the Canadian securities regulatory authorities, available on SEDAR, www.sedar.com or www.mdacorporation.com.
