SUPERVISOR TALKING POINTS

¡ This acquisition accelerates our ability to deliver new, high-value products, systems and services while driving down our customers’ costs – which is critical in today’s tight U.S. government spending environment.

• Share that the integration team will review the worldwide locations of both companies. Where it makes sense, we may consolidate facilities as appropriate.

• Share that the integration team will also be working to understand both companies to determine the best organizational structure. No decisions have been made and more information will be shared as progress occurs over the next 12-18 months.

• Acknowledge that the uncertainty of organizational changes can be difficult.

• Remind employees that Harris and Exelis still operate as independent companies until the transaction is complete. It’s important that the two organizations do not collaborate outside of the normal course of business, and we should not promote ourselves as one company to any stakeholders or the general public.

• Express to employees that we should continue operating business as usual. Where we compete with Exelis, we should continue to compete as we have in the past.

• End the discussion on a positive note. Harris firmly believes that the success of our combined company will rely on our employees and we have every intention of cultivating talented people. This is the place where employees can make a difference, and the new company will provide exciting and broad opportunities.

• Remind employees it’s important we all stay focused on our day-to-day responsibilities and delivering against our objectives and our customer expectations.

• Encourage employees to come forward with their questions and viewpoints later, after they’ve had time to digest the information further. Also remind employees to periodically visit the microsite on connect.harris.com which will be updated as new information is available.
