For the period commencing on the Closing Date and ending on the second anniversary of the Closing Date (the “ Initial Period ”), you will continue to serve as the Chief Executive Officer of the Company and report directly to the Company’s Board of Directors (the “ Board ”).  You will also continue to serve as Chairman of the Board after the Closing Date.

|2. | Compensation.

During the Initial Period, your annual base salary will be $1,450,000, your target annual cash bonus award will be $2,500,000, the target value of your annual long-term incentive awards will be $10,250,000 and in no case will your annual base salary, annual bonus target, annual bonus payment, target value of your annual long-term incentive award or annual long-term incentive award be less than that paid or granted by the Company to Christopher Kubasik (assuming you remain employed for the full fiscal year in respect of which such bonus or award is earned). 1 To the extent that normal annual compensation review cycles occur prior to Closing, the Company may (but is not required to) adjust your compensation elements to amounts not exceeding the contemplated levels in the preceding sentence.


During the Subsequent Period, your annual base salary, target annual cash bonus award and target value of your long-term incentive awards will be determined by the Compensation Committee of the Board (the “ Compensation Committee ”) prior to the commencement thereof ; provided that in no event will your annual base salary, annual bonus target, annual bonus payment, target value of your annual long-term incentive award or annual long-term incentive award be less than that paid or granted by the Company to Christopher Kubasik (assuming you remain employed for the full fiscal year in respect of which such bonus or award is earned).  Notwithstanding the foregoing, the Compensation Committee will retain discretion to increase, but not decrease, the amount of your annual base salary, annual bonus target, annual bonus payment, target value of your annual long-term incentive award and your annual long-term incentive award at any time during the Initial Period and Subsequent Period, provided that any adjustment applied to such amounts will be equally applied to Christopher Kubasik’s annual base salary, annual bonus target, annual bonus payment, target value of his annual long-term incentive award and his annual long-term incentive award, as applicable.  Commencing January 1, 2020, you will be eligible for benefits and perquisites at levels no less favorable than those provided to Christopher Kubasik.


No later than 30 days following the Closing Date (or, if that date occurs within a “quiet period” under the Company’s equity grant policy, the first trading date following the end of such “quiet period”), you will receive a one-time integration award comprised of (i) performance stock units with a target value of $2,500,000 (the “ Integration PSUs ”) and (ii) performance-based non-qualified stock options with a grant date value of $5,000,000 and a 10-year term (the “ Integration Options ” and collectively, with the Integration PSUs, the “ Integration Award ”).  Both components of the Integration Award will be subject to three-year cliff-vesting.  The Integration PSUs will be subject to a 0 to 2 times target payout for the achievement of cost synergy goals from the Closing Date through December 31, 2021 and a separate 0.5 to 2 times modifier of any such earned payouts for achievement of a cumulative earnings per share goal over the same period, in each case as established by the Compensation Committee in good faith in consultation with you and communicated to you at the time of grant.  The actual earned value of the Integration PSUs will be determined by the Compensation Committee based on its assessment of the achievement of the applicable performance objectives.  The Integration PSUs will accrue dividends in an amount equal

to the cash dividends or other distributions, if any, which are paid during the performance period and will be paid upon settlement of the earned Integration PSUs.  The Integration Options will be subject to a performance-vesting condition such that the award will vest and become exercisable only if 80% of the cost synergy goal is achieved.  The Integration Award will be in addition to the long-term incentive award opportunity in the preceding paragraphs and the Integration Award will be on terms and conditions determined by the Compensation Committee that are the same as the equity-based integration awards granted to other senior executives of the Company generally.

|4. | Acknowledgments.

President and Chief Operating Officer of the Company of the duties and responsibilities specified in Paragraph 1 above, (ii) your transition to Executive Chairman at the completion of the Initial Period or (iii) your retirement after the Subsequent Period.

In addition, the definition of “Cause” contained in your CIC Agreement and your Employment Agreement will include as a clause thereof, “an independent third-party investigator mutually agreed to by you and the Company determines that you have engaged in an act of personal misconduct that (1) is a willful and substantial violation of the Company’s Corporate Policy on Equal Employment Opportunity, Anti-Harassment and Non-Retaliation (or any successors thereto) and there is a material risk that such action could cause meaningful harm to the Company (reputationally or otherwise) or (2) gives rise to a material risk of meaningful harm to the Company (reputationally or otherwise) under federal or applicable state law for discrimination or sexual harassment to subordinate employees”.  Further, you agree that if the Board reasonably believes that facts exist that may justify a termination of your employment for “Cause” under your CIC Agreement (or, for actions committed after the second anniversary of the Closing Date, your Employment Agreement), the Board retains the right to place you on a paid leave of absence for up to 10 calendar days pending its investigation of your conduct and the Board’s decision to place you on paid leave will not constitute grounds for you to terminate your employment for “Good Reason” under your CIC Agreement or be deemed a “Constructive Termination” under your Employment Agreement; provided , that nothing shall alter the Company’s obligations under this letter or your CIC Agreement or Employment Agreement, as applicable, and you shall continue to vest in any outstanding equity awards and other benefits during such period of paid leave.


You acknowledge and agree that Section 10 of your Employment Agreement ( Certain Covenants ) and Section 11 of your Employment Agreement ( Confidentiality; Intellectual Property )  are not modified by this letter and accordingly, remain in full force and effect.

|5. | Miscellaneous.

This letter will be governed and construed in accordance with the laws of the State of Florida, without regard to conflicts of laws principles thereof; provided that all matters relating to the amendment of your CIC Agreement will be governed and construed in accordance with the laws of the State of Delaware pursuant to Section 16 thereof.  This letter may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives.  The invalidity or unenforceability of any provision of this letter will not affect the validity or enforceability of any other provision hereof, and this letter will be construed as if such invalid or unenforceable provision were omitted (but only to the extent that such provision cannot be appropriately reformed or modified).  Upon the expiration or other termination of this letter, the respective rights and obligations of the parties hereto will survive such expiration or other termination to the extent necessary to carry out the intentions of the parties under this letter.  This letter may be executed in separate counterparts, each of which is deemed to be an original and all of which taken together constitute one and the same agreement.  Prior to the Closing Date the parties agree not to amend this letter without the consent of L3.
