SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements and other information included in this press release constitute “forward-looking information” or “forward-looking statements” (collectively, “forward-looking statements”) under applicable securities laws, including the Private Securities Litigation Reform Act of 1995. Statements including words such as “may”, “will”, “could”, “should”, “would”, “plan”, “potential”, “intend”, “anticipate”, “believe”, “estimate” or “expect” and other words, terms and phrases of similar meaning are forward-looking statements. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Such forward-looking statements include, but are not limited to, statements as to MDA’s and DigitalGlobe’s management’s expectations with respect to: the combined company’s plans, objectives, expectations and intentions; the ability of DigitalGlobe and MDA to obtain the requisite regulatory approvals and satisfy the remaining conditions to closing; the anticipated timing for the closing of the merger; and other statements that are not historical facts.

Forward-looking statements in this press release are based on certain key expectations and assumptions made by MDA and DigitalGlobe, including expectations and assumptions concerning: the receipt, in a timely manner, of regulatory, stock exchange, shareholder and other third party approvals in respect of the transaction; satisfaction of other closing conditions; consummation of financing related to the transaction; and the belief that the merger poses no threat to the national security of the United States. Although management of MDA and DigitalGlobe believe that the expectations and assumptions on which such forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because MDA and DigitalGlobe can give no assurance that they will prove to be correct.

Forward-looking statements are subject to various risks and uncertainties which could cause actual results and experience to differ materially from the anticipated results or expectations expressed in this press release. Some of the key risks and uncertainties include, but are not limited to: changes in government priorities, mandates, policies, funding levels, contracts and regulations, including the grant and maintenance of security clearances, loss or reduction in scope of any of our primary contracts, or decisions by customers not to exercise renewal options; growth in the businesses of our customers and the ability of our customers to develop new services; inherent risks of performance on firm fixed price construction contracts and termination of contracts by customers for convenience; decrease in demand for our products and services; failure to maintain technological advances and offer new products to retain customers and market position; reliance on a limited number of vendors to provide certain key products or services to us; breach of our system security measures or loss of our secure facility clearance and accreditation; the loss or damage to any of our satellites; delays in the construction and launch of any of our satellites or our ability to achieve and maintain full operational capacity of all our satellites; potential for product liability or the occurrence of defects in products or systems and resulting loss of revenue and harm to our reputation; detrimental reliance on third parties for data; interruption or failure of our ground systems and other infrastructure; increased competition that may reduce our market share or cause us to lower our prices; changes in political or economic conditions, including fluctuations in the value of foreign currencies, interest rates, energy and commodity prices, trade laws and the effects of governmental initiatives to manage economic conditions; our ability to recruit, hire or retain key employees or a highly skilled and diverse workforce; potential for work stoppages; failure to obtain or maintain required regulatory approvals and licenses; failure to comply with environmental regulations; and changes in U.S., Canadian or foreign law or regulation that may limit our ability to distribute our products and services. There are also risks that are inherent in the nature of the pending merger transaction, including: failure to realize anticipated synergies or cost savings; risks regarding the integration of the two companies; and failure to obtain any required regulatory and other approvals (or to do so in a timely manner). The anticipated timeline for completion of the transaction may change for a number of reasons, including the inability to secure necessary regulatory, stock exchange or other approvals in the time assumed or the need for additional time to satisfy the conditions to the completion of the transaction. As a result of the foregoing, readers should not place undue reliance on the forward-looking statements contained in this press release concerning the timing of the transaction. Additional information concerning these and other risk factors can be found in MDA’s filings with Canadian securities regulatory authorities, which are available online under MDA’s profile at www.sedar.com or on MDA’s website at www.mdacorporation.com , and in DigitalGlobe’s filings with the SEC, including Item 1A of DigitalGlobe’s Annual Report on Form 10-K for the year ended December 31, 2016.
