Attention: David H. Fogg, Vice President—Treasurer

Ladies and Gentlemen:

General Dynamics Corporation (the “ Borrower ”) has requested that (i) JPMorgan Chase Bank, N.A. (“ JPMorgan ”) and Wells Fargo Securities, LLC (“ WFS ”, and collectively with JPMorgan, the “ Arrangers ”) agree to structure, arrange and syndicate a 364-day incremental revolving credit facility (the “ Facility ”) in the initial aggregate principal amount of up to $7.5 billion (the “ Aggregate Commitment ”), (ii) JPMorgan and Wells Fargo Bank, National Association (“ WFBNA ”, and collectively with JPMorgan, the “ Commitment Parties ”) commit to provide a portion of the Facility, (iii) JPMorgan agrees to serve as administrative agent for the Facility and (iv) WFBNA agrees to serve as syndication agent for the Facility.

The Arrangers are pleased to advise the Borrower that they are willing to act as joint lead arrangers and joint bookrunners for the Facility. Furthermore, and subject to the terms and conditions herein, (i) each Commitment Party is pleased to advise the Borrower of (a) its several commitment to provide $1,275,000,000 of the Aggregate Commitment on the Closing Date (as defined in the Term Sheet) (collectively, the “ Commitment Parties Commitments ”), (ii) each Arranger is pleased to advise the Borrower of its agreement to use commercially reasonable efforts to assemble a syndicate of financial institutions identified by the Arrangers in consultation with the Borrower (together with JPMorgan and WFBNA, the “ Lenders ”) to provide the balance of the Aggregate Commitment for the Facility, (iii) JPMorgan is pleased to offer to act as administrative agent for the Facility and (iv) WFBNA is pleased to offer to act as syndication agent for the Facility, in each case upon the terms and subject to the conditions set forth or referred to in this commitment letter and in the Confidential Term Sheet attached hereto as Exhibit A (the “ Term Sheet ” and, together with this commitment letter, the “ Commitment Letter ”). It is a condition to each Commitment Party’s commitment hereunder that the portion of the Aggregate Commitment not being provided by the Commitment Parties shall be provided by the other Lenders.

It is agreed that JPMorgan will act as the sole and exclusive administrative agent, that WFBNA will act as the sole and exclusive syndication agent and that the Arrangers will act as sole and exclusive joint lead arrangers and joint bookrunners for the Facility; provided that (i) the Borrower agrees that JPMorgan may perform its responsibilities hereunder through its affiliate, J.P. Morgan Securities LLC and (ii) the Borrower may appoint up to two (2) other financial institutions as joint bookrunners, joint

lead arrangers and co-documentation agents so long as each such institution (or its leading affiliate) commits to the Facility an amount that is no less than each Commitment Party’s commitment hereunder. It is agreed that JPMorgan will have “left placement”, WFS will have “middle placement”, and the remaining arrangers and bookrunners will be subsequently listed in alphabetical order in the Confidential Information Memorandum referred to below and in all other marketing materials or advertisements related to the Facility.

The Arrangers will use their best efforts to form a syndicate of Lenders to provide the additional commitments required to complete the Facility. The Borrower agrees that, except as provided in clause (ii) of the immediately preceding paragraph, no other titles will be awarded, and no compensation (other than that expressly contemplated by the Term Sheet and the Fee Letter referred to below) will be paid, in connection with the Facility, unless in each case the Borrower and the Arrangers shall so agree. Each of the Arrangers reserves the right to allocate the relevant Commitment Parties Commitment among its affiliates.

The Arrangers will, in consultation with the Borrower, manage all aspects of the syndication, including, without limitation, decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted, which institutions will participate, designation of titles, the allocations of the commitments among the Lenders and the amount and distribution of the fees among the Lenders. The Borrower agrees to participate actively in the preparation of an information package regarding the operations and prospects of the Borrower to be used in connection with the syndication, including a Confidential Information Memorandum (collectively with the Term Sheet, the “ Information Materials ”), and the presentation of the Information Materials to prospective Lenders. Before distribution of any Information Materials, the Borrower agrees to execute and deliver to the Arrangers a letter in which the Borrower authorizes distribution of the Information Materials to a prospective Lender’s employees, subject to the agreement by each such prospective Lender to maintain the confidentiality of the Information Materials on terms set forth in the Information Materials and approved by the Borrower (such approval not to be unreasonably withheld or delayed). You hereby authorize the Arrangers and the Commitment Parties to download copies of the Borrower’s trademark logos from its website and post copies thereof on the IntraLinks site or similar workspace established by the Arrangers to syndicate the Facility and use the logos on any confidential information memorandum, presentations and other marketing materials prepared in connection with the syndication of the Facility. The Borrower agrees that, prior to and during the syndication of the Facility, neither it nor any of its subsidiaries shall place, arrange or renew any commercial bank or other credit facilities, other than a Five-Year multicurrency revolving credit facility as contemplated by that certain commitment letter dated the date hereof among the Borrower and the Arrangers.

The obligation of the Commitment Parties and the other Lenders to make loans under the Facility is subject to the following: (i) the preparation, execution and delivery of a 364-day credit agreement (“ Credit Agreement ”) and other loan documents (collectively, together with the Credit Agreement, the “ Loan Documents ”) mutually acceptable to the Borrower and the Lenders incorporating, without limitation, substantially the terms and conditions outlined herein and in the Term Sheet; (ii) receipt of commitments from other Lenders on the terms and conditions of the attached Term Sheet for the balance of the Aggregate Commitment; and (iii) the Commitment Parties’ determination that there is no material adverse change in the business, financial condition or results of operations of the Borrower and its subsidiaries, taken as a whole, from December 31, 2017.

The Arrangers will have no responsibility other than to arrange the syndication as set forth herein. The Arrangers and the Commitment Parties are acting solely in the capacity of an arm’s length contractual counterparty to the Borrower with respect to the arrangement of the Facility (including in connection with determining the terms of the Facility) and the other services described herein (as applicable) and not as a

financial advisor or a fiduciary to, or an agent of, the Borrower or any other person. The Borrower agrees that it will not assert any claim against any Arranger or Commitment Party based on an alleged breach of fiduciary duty by such Arranger or Commitment Party in connection with this Commitment Letter and the transactions contemplated hereby. Additionally, the Borrower acknowledges and agrees that the Arrangers and the Commitment Parties are not advising the Borrower as to any legal, tax, investment, accounting, regulatory or any other matters in any jurisdiction. The Borrower shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Arrangers and Commitment Parties shall have no responsibility or liability to the Borrower with respect thereto. Any review by the Arrangers and Commitment Parties of the Borrower, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Arrangers and the Commitment Parties and shall not be on behalf of the Borrower.

The Borrower hereby agrees to reimburse the Arrangers and Commitment Parties for all reasonable and documented out-of-pocket expenses (including the reasonable fees, time charges and expenses of one primary counsel for the Arrangers and Commitment Parties) incurred in connection with the preparation, negotiation, execution, syndication and distribution (including, without limitation, via Intralinks) of this Commitment Letter, the fee letter delivered with the Commitment Letter (the “ Fee Letter ”), the Loan Documents and any other documentation contemplated hereby or thereby. The Borrower hereby agrees to reimburse the Arrangers and Commitment Parties for all reasonable and documented out-of-pocket expenses (including the reasonable fees, time charges and expenses of one primary counsel for the Arrangers and Commitment Parties, taken as a whole, and one additional local counsel in each applicable jurisdiction for the Arrangers and Commitment Parties, taken as a whole, and additional counsel in light of actual or potential conflicts of interest) incurred in connection with the enforcement of this Commitment Letter, the Fee Letter, the Loan Documents and any other documentation contemplated hereby or thereby. The Borrower hereby further agrees to indemnify and hold harmless the Arrangers, the Commitment Parties, and their respective officers, employees, agents and directors (each an “ indemnified party ”) against any and all losses, claims, damages, costs, expenses (including the reasonable and documented fees, time charges and expenses of one primary counsel for all indemnified parties, taken as a whole, and a single local counsel in each applicable jurisdiction for all such indemnified parties, taken as a whole, and additional counsel in light of actual or potential conflicts of interest) or liabilities of every kind whatsoever (collectively, the “ Indemnified Obligations ”) to which each of the indemnified parties may become subject directly related to and arising solely from the matters which are the subject of this Commitment Letter, including, without limitation, expenses incurred in connection with investigating or defending against any liability or action (whether or not such indemnified party is a party thereto), except that the Borrower shall not be liable for any Indemnified Obligations of any indemnified party to the extent any of the foregoing is found in a final judgment by a court of competent jurisdiction to have arisen or resulted from (i) the gross negligence, bad faith or willful misconduct of the respective indemnified party or any Related Indemnified Person (as defined below) of such indemnified party, (ii) a material breach of the express obligations of any indemnified party or any Related Indemnified Person thereof under this Commitment Letter, the Fee Letter or the Loan Documents, or (iii) any claim, litigation, investigation or proceeding (except to the extent involving any act or omission by you or any of your affiliates) brought by any indemnified party against any other indemnified party or any Related Indemnified Person of any indemnified party (other than claims against any indemnified party or any of its Related Indemnified Persons in its capacity or in fulfilling its role as an agent, arranger, bookrunner or any similar role with respect to the Facility). For purposes hereof, a “ Related Indemnified Person ” of an indemnified party means (1) any controlling person or controlled affiliate of such indemnified party, (2) the respective directors, officers or employees of such indemnified party or any of its controlling persons or controlled affiliates and (3) the respective agents, advisors and representatives of such indemnified party or any of its controlling persons or controlled affiliates, in the case of this clause (3), acting at the instructions of such indemnified party, controlling person or such controlled affiliate; provided that each reference to a controlling person, controlled

affiliate, director, officer or employee in this sentence pertains to a controlling person, controlled affiliate, director, officer or employee involved in the structuring, arrangement, negotiation or syndication of the Commitment Letter and the Facility. Neither the Arrangers, any Commitment Party nor any other Lender shall be liable under this Commitment Letter or any Loan Document or in respect of any act, omission or event relating to the transaction contemplated hereby or thereby, on any theory of liability, for any special, indirect, consequential or punitive damages.

The Borrower’s obligations under the immediately preceding paragraph shall continue and are and shall remain absolute obligations of the Borrower, unless and until superseded by the reimbursement and indemnity provisions of definitive Loan Documents, whether or not Loan Documents are executed or any loan is made by the Lenders or any conditions of lending are met. The obligations of the Arrangers, the Commitment Parties and the other Lenders under this Commitment Letter shall be enforceable solely by the Borrower and may not be relied upon by any other person. For purposes of this and the immediately preceding paragraph, the terms “Commitment Parties” and “Arrangers” shall include affiliates thereof.

This Commitment Letter and the Fee Letter are for the Borrower’s confidential use only and may not be disclosed by it to any person other than its employees, attorneys and financial advisors (but not commercial lenders), and then only in connection with the proposed transaction and on a confidential basis, except where (in the Borrower’s reasonable judgment) disclosure is required by law or where the Commitment Parties or the Arrangers consent to the proposed disclosure, which consent shall not be unreasonably withheld. Officers, directors, employees and agents of each of the Arrangers and the Commitment Parties and their respective affiliates shall at all times have the right to share amongst themselves information received from the Borrower and its affiliates and their respective officers, directors, employees and agents. Each of the Commitment Parties and the Arrangers reserve the right to assign some or all of its rights and delegate some or all of its responsibilities hereunder to one of its affiliates or branch offices (including each Commitment Party’s responsibility to fund some or all of the Commitment Parties Commitments in the currencies described in the Term Sheet). This Commitment Letter supersedes any and all prior versions hereof or thereof. This Commitment Letter may only be amended by a writing signed by all parties hereto. This Commitment Letter may be executed in any number of counterparts, each of which shall be an original, and all of which, when taken together, shall constitute one agreement. Delivery of an executed signature page of this Commitment Letter by electronic or facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. This Commitment Letter and the Fee Letter are the only agreements that have been entered into among the parties hereto and thereto with respect to the Facility and set forth the entire understanding of such parties with respect hereto and thereto.

This Commitment Letter shall be governed by, and construed and interpreted in accordance with, the law of the State of New York. Each of the parties hereto consents to the exclusive jurisdiction and venue of the state or federal courts located in the Borough of Manhattan in the City of New York. Each party hereto irrevocably waives, to the fullest extent permitted by applicable law, (a) any right it may have to a trial by jury in any legal proceeding arising out of or relating to this Commitment Letter, the Fee Letter or the transactions contemplated hereby or thereby (whether based on contract, tort or any other theory) and (b) any objection that it may now or hereafter have to the laying of venue of any such legal proceeding in the state or federal courts located in the Borough of Manhattan in the City of New York. The Borrower, each Commitment Party and each Arranger irrevocably agrees to waive trial by jury in any suit, action, proceeding, claim or counterclaim brought by or on behalf of any party related to or arising out of the transactions contemplated by this Commitment Letter or the Fee Letter or the performance of services contemplated hereby or thereby.

conflicting interests regarding the transactions described herein and otherwise. None of the Commitment Parties, the Arrangers nor any of their affiliates will use confidential information obtained from the Borrower by virtue of the transactions contemplated by the Commitment Letter, the Fee Letter or their other relationships with the Borrower in connection with the performance by the Commitment Parties, the Arrangers and their respective affiliates of services for other companies, and will not furnish any such information to other companies. The Borrower also acknowledges that each Commitment Party and each Arranger has no obligation to use in connection with the transactions contemplated by the Commitment Letter, or to furnish to the Borrower, confidential information obtained from other companies. You further acknowledge that each Arranger and each Commitment Party is a full service securities or banking firm engaged in, as applicable, securities trading and brokerage activities as well as providing investment banking and other financial services. In the ordinary course of business, any Arranger or Commitment Party may provide investment banking and other financial services to, and/or acquire, hold or sell, for its own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of, you and other companies with which you may have commercial or other relationships. With respect to any securities and/or financial instruments so held by any Arranger or Commitment Party or any of its customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the holder of the rights, in its sole discretion.

Each Commitment Party and each Arranger may employ the services of its affiliates in providing certain services hereunder and, in connection with the provision of such services, may exchange with such affiliates information concerning the Borrower and the other companies that may be the subject of the transactions contemplated by this Commitment Letter, and, to the extent so employed, such affiliates shall be entitled to the benefits of such Commitment Party or Arranger hereunder and shall also be subject to the terms, provisions, restrictions and covenants of such Commitment Party or Arranger hereunder.

The compensation, reimbursement, indemnification and confidentiality provisions contained in this Commitment Letter and in the Fee Letter and any other provision herein or therein which by its terms expressly survives the termination of this Commitment Letter shall remain in full force and effect notwithstanding the termination of this Commitment Letter or each Commitment Party’s commitment hereunder; provided, however, that upon the execution and delivery of the Loan Documents by the Borrower, the Administrative Agent and the Lenders, the reimbursement and indemnification provisions contained herein shall automatically terminate and be superseded by the reimbursement and indemnification provisions of the Loan Documents.

Each Commitment Party and each Arranger hereby notifies the Borrower that pursuant to the requirements of the U.S.A. PATRIOT ACT (Title III of Pub. L. 107 56 (signed into law October 26, 2001)) (the “ Patriot Act ”), it and each of the Lenders may be required to obtain, verify and record information that identifies the Borrower and its subsidiaries, which information may include the name and address and other information that will allow such Commitment Party and such Arranger and each of the Lenders to identify the Borrower and its subsidiaries in accordance with the Patriot Act.
