Dear Colleagues,

It has been a busy few weeks since we announced our transformative Merger of Equals with Harris Corporation. We’ve been making progress on our integration planning, so I wanted to provide you with a brief update.

Over the past several weeks I’ve been highly engaged with our customers, employees and shareholders. There is a shared enthusiasm about the many possibilities resulting from the proposed merger; it’s apparent that this combination will give us the scale necessary to better compete in the marketplace.

At the core of this merger, it’s about you, the employee, and it’s together that we will build the future of L3. The combination of our strengths will allow us to be even more competitive, execute better against our customer priorities and accelerate the pace of our innovative solutions. I encourage you to embrace the changes ahead and remember that our expanded company will present you with even more fulfilling and rewarding career opportunities.

We and Harris have created an Integration Management Office (IMO), which will be jointly staffed by experienced leaders from both companies across all of our functional teams. The IMO will manage functional and business integration project delivery and planning and will ensure our efforts remain on track from now until closing and beyond. Harris’ CEO Bill Brown and I will oversee the IMO Steering Committee, and will work closely with the IMO to establish objectives and guiding principles for integration.

One of my key priorities is to ensure this is a seamless integration with minimal disruption to our business. Heidi Wood, SVP, Corporate Strategy & Technology, and James Jordano, VP, Integration & Global Business Services, have been appointed as the Integration Leaders for L3 and Harris, respectively. In addition, McKinsey & Company has been engaged to support the merger integration, and we will look to them to provide the right tools and approaches for a successful and smooth execution. This week, we will have a kick-off merger integration meeting in Melbourne, FL to begin the process of establishing our charter, building the roadmap and defining our path forward.

As a reminder, the transaction is expected to close in mid-2019. In the meantime, it’s imperative we keep our focus on our day-to-day work.

I remain committed to keeping you informed of our progress. You can also visit the L3 Intranet for the latest FAQs on the merger. For any other questions, please continue to reach out to your Segment Leadership or email questions to merger.questions@L3T.com.

As we take this unique and exciting step forward, I hope you are inspired and share my enthusiasm. Thank you for your ongoing support and dedication to L3 and to your contributions for a brighter future ahead.

Sincerely,

All statements other than historical facts may be forward-looking statements; words such as “may,” “will,” “should,” “likely,” “projects,” “financial guidance,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” and similar expressions are used to identify forward-looking statements. L3 and Harris caution investors that these statements are subject to risks and uncertainties, many of which are difficult to predict and generally beyond L3’s and Harris’ control, that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. In addition to factors previously disclosed in L3’s and Harris’s reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of L3 and Harris to terminate the definitive merger agreement between L3 and Harris; the outcome of any legal proceedings that may be instituted against L3, Harris or their respective directors; the risk that the stockholder approvals of L3 or Harris may not be obtained on the expected schedule or at all; the ability to obtain regulatory approvals and satisfy other closing conditions to the merger in a timely manner or at all, including the risk that regulatory approvals required for the merger are not obtained or are obtained subject to conditions that are not anticipated; delay in closing the merger; difficulties and delays in integrating the L3 and Harris businesses or fully realizing anticipated cost savings and other benefits; business disruptions from the proposed merger that may harm L3’s or Harris’s businesses, including current plans and operations; any announcement relating to the proposed transaction could have adverse effects on the ability of L3 or Harris to retain and hire key personnel or maintain relationships with suppliers and customers, including the U.S. government and other governments, or on L3’s or Harris’s operating results and businesses generally; the risk that the announcement of the proposed transaction could have adverse effects on the market price of the common stock of either or both of L3’s and Harris’s common stock and the uncertainty as to the long-term value of the common stock of the combined company following the merger; certain restrictions during the pendency of the merger that may impact L3’s or Harris’s ability to pursue certain business opportunities or strategic transactions; the business, economic and political conditions in the markets in which L3 and Harris operate; and events beyond L3’s and Harris’s control, such as acts of terrorism.

These forward-looking statements speak only as of the date of this communication or as of the date they were made, and neither L3 nor Harris undertakes any obligation to update forward-looking statements. For a more detailed discussion of these factors, also see the information under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in L3’s and Harris’s most recent reports on Form 10-K for the years ended December 31, 2017 and June 29, 2018, respectively, and any material updates to these factors contained in any of L3’s and Harris’s subsequent and future filings.

As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. Given these uncertainties, you should not place any reliance on these forward-looking statements.
