Consulting Agreement

June 6, 2012

Mr. Jay L. Johnson

Dear Mr. Johnson:

This letter agreement (“Agreement”) confirms the contractual arrangement between General Dynamics Corporation (the “Company,” “us,” or “we”) and Mr. Jay L. Johnson (“Consultant” or “you”) for the personal services of Consultant described in more detail below.

The term of this Agreement shall be from January 1, 2013, until June 30, 2013 (the “Consulting Period”). Consultant’s obligations under Section 5 of this Agreement shall survive the expiration or termination of this Agreement.

(a) The Company retains Consultant to render, and Consultant hereby agrees to render to the Company, upon request, strategic advice and guidance regarding the aerospace and defense market and particular matters of importance to the Company’s business. These services will include conference calls, review of relevant materials, and attendance at meetings, and may include occasional travel. All such services shall be referred to herein as “the Services.”

(b) The Parties anticipate that the level of services to be provided by Consultant during the Consulting Period will be no more than twenty percent (20%) of the average level of services provided by Consultant during his tenure as Chairman and Chief Executive Officer. On a weekly basis, the parties do not expect that the Services shall entail more than an average of eight hours of work per week.

(c) As a self-employed independent contractor, Consultant retains control over the manner and means by which Consultant provides the Services, provided that we determine the objectives of the Services and timeframes for completion. Consultant is not required to work any fixed schedule and will set his own hours, subject to deadlines required by the Company. With the exception of in-person meetings that may be scheduled at times that are mutually convenient to the Company and Consultant, Consultant will not be required to work at any particular location.

(a) In consideration for the Services, the Company shall pay Consultant a fee of Eight Hundred Twenty-Five Thousand dollars ($825,000.00) (“the Retainer”). The Retainer shall be paid to Consultant in a single, lump sum on or before January 31, 2013 but in no event prior to January 1, 2013 and shall compensate Consultant for all services performed and hours worked during the Consulting Period.

(b) Reimbursement for all out-of-pocket expenses will be based on reasonable commercial practices and actual cost, provided that the Company will reimburse Consultant only for expenses for airfare, transportation, meals, and lodging that Consultant incurs in the course of out-of-town travel requested and approved in advance by the Company. Expenses must be supported by receipts and be submitted in accordance with the Company’s standard practices for expense reimbursement. Per standard policy, all invoices submitted for payment are subject to review or audit by us, and Consultant must maintain copies of receipts for six years from the date of the relevant invoice.

(c) Subject to Consultant’s continued performance of the Services in accordance with this Agreement for the period beginning on January 1, 2013 and ending on June 30, 2013, the Company will provide office space and administrative support for the Consultant in the Washington, D.C. area for this time period. Consultant shall be responsible for all costs or expenses outside this time period.

During the Consulting Period, Consultant may provide consulting, advisory or other services to other persons or entities and may serve as a director or be employed by other persons or entities, provided that Consultant shall not violate the restrictive covenants set forth in Section 3 of the June 6, 2012 Retirement Agreement between Consultant and the Company (the “Retirement Agreement”), which obligations are expressly incorporated herein. Consultant further agrees and covenants that, during the Consulting Period, all services he performs for the Company in connection with any government program or business opportunity shall be limited solely to the exclusive benefit of General Dynamics and its subsidiaries.

(a) Use and Disclosure of Confidential Information. You acknowledge and agree that any Confidential Information (as such term is defined in the Retirement Agreement) that the Company provides you (even if you previously acquired that information while employed by the Company), will not be used by you for any purpose other than for the sole and exclusive benefit of the Company. You further agree that all Confidential Information shall remain our property and that, subject to the same exceptions that permit disclosure under the Retirement Agreement, you will not disclose such information to any third party without our prior written approval, during or after the term of this Agreement. Upon our written request or the conclusion of this Agreement, whichever is earlier, you will promptly return to us all Confirmation Information in whatever form (including computer files and other electronic data) provided to you during the

2

Consulting Period. Nothing in this Agreement shall limit or extinguish your obligations under the Retirement Agreement to maintain confidentiality of trade secrets and other information relating to the Company’s business.

b. Intellectual Property. All documents, writings, presentations, or other copyrightable materials that you produce and deliver to us as work done in connection with the Services shall constitute “works for hire” prepared for us, and as such, General Dynamics is and shall be the sole owner of all right, title, and interest in the copyright of all such materials. You shall promptly notify us of any limitation of which you are or become aware concerning materials you deliver to us.

At all times, the relationship between us shall be that of independent contractors, and nothing herein shall be construed to create or imply any employer-employee, principal-agent, partnership, joint venture, or other relationship between us. You shall hold no authority, express or implied, to obligate us or make representations on our behalf and shall make no representation to others to the contrary.

Amounts paid to you hereunder will be reported on IRS Form 1099-Misc. You are solely responsible for payment of all taxes arising out of your activities in connection with the Services, including, without limitation, federal and state income taxes, self employment taxes, and any other taxes or business license fees as required. We shall not be responsible for paying any income or taxes on your behalf.

No amount payable hereunder shall be counted for purposes of calculating or accruing any benefit or service for purposes of any pension, retirement, health, welfare, or other benefit plan or program. Your performance of the Services will not count toward, and does not and will not make you eligible to participate in, any benefit plan or program in which employees of GD or its subsidiaries or affiliates participate.

Consultant will comply with all federal, state, and local laws, regulations, licensing and registration requirements, and rules that apply to Consultant’s activities in connection with the Services.

(a) Disputes. Any dispute, controversy, or claim arising out of or in connection with this Agreement, including any question regarding its existence, validity or termination, shall be finally resolved by arbitration under the rules of the American Arbitration Association in force as of the date of this Agreement, which rules are deemed to be incorporated by reference into this clause. The place of arbitration shall be Fairfax County, Virginia.

(b) Complete Agreement. This Agreement and the Retirement Agreement constitute the entire understanding of the Company and the Consultant with respect to the subject matter

3

hereof and together supersede all prior understandings, written or oral.

(c) Amendment; Waiver. The terms of this Agreement may be changed, modified or discharged only by an instrument in writing signed by the parties hereto. A failure of the Company or the Consultant to insist on strict compliance with any provision of this Agreement shall not be deemed a waiver of such provision or any other provision hereof.

(d) Construction of Agreement. Each party has negotiated the terms and provisions of this Agreement and has had the opportunity to contribute to its revision. The terms of this Agreement shall be construed fairly and evenly as to both parties hereto and not in favor or against either party based on the characterization of one or the other as the drafting party.

(e) Choice of Law. This Agreement shall be construed, enforced and interpreted in accordance with and governed by the laws of the Commonwealth of Virginia, without regard to its choice of law principles.

(f) Successors and Assigns. This Agreement is binding upon, and shall inure to the benefit of, the parties and their respective heirs, successors and assigns, it being acknowledged and agreed that the obligation of the Consultant to provide personal services to the Company shall not be assignable by him.

(g) Section 409A. The intent of the Parties is that any payments and benefits under this Agreement that are subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) comply with the requirements of Section 409A of the Code and any related regulations and other guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service. Accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered in compliance therewith. All expense reimbursements paid pursuant to this Agreement that are taxable income to Consultant shall in no event be paid later than the end of the calendar year next following the calendar year in which Consultant incurs such expense. With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by this Agreement and Section 409A of the Code, the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit and the amount of expenses eligible for reimbursement, or in-kind benefits provided, during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year.
