Dear Wes:

It is my sincere pleasure to offer you the position as President of the Integrated Defense Systems (IDS) business effective July 30, 2015, reporting to me. I look forward to you joining our Leadership team. Your position will be an officer and vice president of the corporation. The position resides in Tewksbury, MA.

The offer details are as follows:

• Your base salary will be $600,000 annually, paid at a bi-weekly rate of $23,077.60. Your next eligibility for a base salary increase will be March, 2016.

• Your Results Based Incentive (RBI) Program target for 2015 will be increased to 100% of your annualized base salary, subject to individual and company performance.

• You will be eligible to participate in the Company’s Long Term Participant Plan (LTPP). As a first time participant, your award value for the 2015 program is $950,000, based on performance achieved at the end of a three-year cycle (2015-2017). Your payout, if earned, may be higher or lower than the initial award value. Participation in this plan is subject to annual review.

• You remain eligible to participate in the annual restricted share award program subject to the terms of the award and the provisions of the Raytheon Stock Plan. Your 2016 restricted stock award is targeted at $975,000, subject to your individual performance and approval by the Board of Directors in 2016.

• You will be required by the end of your fifth (5^th) year in an elected officer capacity to own a minimum of three (3x) times base salary in the form of Raytheon equity. In addition, there is a requirement that each elected officer holds shares of Company "stock owned outright" with a value of at least 1x base salary. Company stock owned outright includes the following Company securities: outright share purchases, shares from restricted stock/unit vestings or acquired upon option exercises; and vested shares or share equivalents in any Company retirement plan (e.g., 401(k), Deferred Compensation Plan).

• If you are involuntarily separated from employment with the Company without cause, as defined in the Raytheon Severance Pay Plan, you will be entitled to a separation payment of one (1) times your annual base salary and target bonus, as well as one (1) years benefits (excluding executive perquisites) as of the date of separation in exchange for a General Release.

• You will be entitled to a Change in Control Severance Agreement which would provide you with severance benefits equal to two (2) times your annual base salary and target bonus as of the date of the change in control in the event of a change in control of the company. Please note that the Change in Control Severance Agreement is structured to require both a change in corporate ownership and a loss of employment as those terms are defined in the draft agreement.
