Each of Parent, Spinco, and RMT Parent is sometimes referred to individually as a “Party” and collectively they are sometimes referred to as the “Parties.”

WHEREAS, in connection with the Agreement and Plan of Merger dated as of January 26, 2016 (the “Merger Agreement”), entered into by and Parent, Spinco, RMT Parent, and Lion Merger Co., a Delaware corporation and wholly owned Subsidiary of RMT Parent, the Parties contemporaneously entered into the Employee Matters Agreement; and

WHEREAS, the Parties desire to amend certain rights and obligations of the Parties under the Employee Matters Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements hereof, and intending to be legally bound hereby, the Parties agree as follows:

Section 1. Definitions. Capitalized terms used in this Amendment but not defined herein shall have the meanings given to them in the Employee Matters Agreement.

Section 2. Amendment to Section 2.03(c) of the Employee Matters Agreement. Section 2.03(c) of the Employee Matters Agreement is hereby amended and restated in its entirety as follows:

“(c) The terms of the Successor Savings Plan, or each such Successor Savings Plan, shall provide that the Spinco Business Employees shall have the right to make direct rollovers to such plan of their accounts in each Parent Savings Plan, other than a direct in-kind rollover of any investments in Lockheed Martin Corporation stock and RMT Parent stock. No Successor Savings Plan shall be obligated to permit investments in Lockheed Martin Corporation stock after the Distribution Date. Each Successor Savings Plan shall also provide that the Spinco Business Employees shall have the right to make direct rollovers to such plan of any notes evidencing loans made to such Spinco Business Employees, as provided in paragraph (d) of this Section 2.03. However, if Parent reasonably determines that a direct rollover from a Parent Savings Plan to a Successor Savings Plan is impermissible under Section 401(k) of the Code, Spinco or the RMT Parent Entity, as the case may be, shall cause the Successor Savings Plan, or each such Successor Savings Plan, to accept a transfer of assets and liabilities with respect to the Spinco Business Employees from the corresponding Parent Savings Plan at such time and in such form as agreed upon by Parent and Spinco or an RMT Parent Entity, as the case may be. If any Spinco Business Employee has a loan that remains outstanding under a

Parent Savings Plan after the Distribution Date, Parent shall provide coupon books to permit such Spinco Business Employee to continue to repay such loan until the earlier of the date such loan is paid in full and the date such loan is rolled over to a Successor Savings Plan as provided in paragraph (d) of this Section 2.03.”
