Exhibit 10.18 -- Form of Severance Protection Agreement



 Exhibit 10.18 
 SEVERANCE PROTECTION AGREEMENT 
 SEVERANCE PROTECTION AGREEMENT dated December
    , 2008, by and between General Dynamics Corporation, a Delaware corporation (the “Company”),
                     and (the “Executive”). 
 The Board of Directors of the Company (the “Board”) recognizes that the possibility of a Change in Control (as hereinafter defined) of the Company exists and that the threat or occurrence of a Change
in Control may result in the distraction of its key management personnel because of the uncertainties inherent in such a situation. 
 The
Board has determined that it is essential and in the best interests of the Company and its stockholders to retain the services of the Executive in the event of the threat or occurrence of a Change in Control and to ensure the Executive’s
continued dedication and efforts in such event without undue concern for the Executive’s personal financial and employment security. 
 In order to induce the Executive to remain in the employ of the Company, particularly in the event of the threat or occurrence of a Change in Control, the Company desires to enter into this Agreement to provide the Executive with certain
benefits in the event the Executive’s employment is terminated as a result of, or in connection with, a Change in Control. 
 NOW,
THEREFORE, in consideration of the respective agreements of the parties contained herein, it is agreed as follows: 
 Section 1.
Definitions. For purposes of this Agreement, the following terms have the meanings set forth below: 
 “Accounting
Firm” has the meaning set forth in Section 5.2. 
 “Accrued Compensation” means an amount which includes all
amounts earned or accrued by the Executive through and including the Termination Date but not paid to the Executive on or prior to such date, including (a) all base salary, (b) reimbursement for all reasonable and necessary expenses
incurred by the Executive on behalf of the Company during the period ending on the Termination Date, (c) all vacation pay and (d) all bonuses and incentive compensation (other than the Pro Rata Bonus). 
 “Base Amount” means the greater of the Executive’s annual base salary (a) at the rate in effect on the Termination Date and
(b) at the highest rate in effect at any time during the 180-day period prior to a Change in Control, and will include all amounts of the Executive’s base salary that are deferred under any qualified or non-qualified employee benefit plan
of the Company or any other agreement or arrangement. 
 “Beneficial Owner” has the meaning as used in Rule 13d-3
promulgated under the Securities Exchange Act. The terms “Beneficially Owned” and “Beneficial Ownership” each have a correlative meaning. 







 “Board” means the Board of Directors of the Company. 
 “Bonus Amount” means the greater of (a) the annual bonus paid or payable to the Executive pursuant to any annual bonus or incentive
plan maintained by the Company in respect of the fiscal year ending immediately prior to the fiscal year in which the Termination Date occurs or (b) the average of the annual bonus paid or payable to the Executive pursuant to any annual bonus
or incentive plan maintained by the Company in respect of each of the three fiscal years ending immediately prior to the fiscal year in which the Termination Date occurs (or, if higher, ending in respect of each of the three fiscal years ending
immediately prior to the year in which the Change in Control occurs). 
 “Cause” for the termination of the Executive’s
employment with the Company will be deemed to exist if the Executive has been convicted of a felony or if the Board determines by a resolution adopted in good faith by at least two-thirds of the Board that the Executive has (a) intentionally
and continually failed to perform in all material respects the Executive’s reasonably assigned duties with the Company (other than a failure resulting from the Executive’s incapacity due to physical or mental disability or illness or from
the Executive’s assignment of duties that would constitute Good Reason for the Executive’s termination of employment with the Company) which failure has continued for a period of at least 30 days after a written notice of demand for
performance has been delivered to the Executive specifying the manner in which the Executive has failed in all material respects to so perform or (b) intentionally engaged in conduct which is demonstrably and materially injurious to the
Company; provided that no termination of the Executive’s employment will be for Cause as set forth in clause (b) hereof unless (i) there has been delivered to the Executive a written notice specifying in reasonable detail the conduct
of the Executive of the type described in clause (b) and (ii) the Executive has been provided an opportunity to be heard in person by the Board (with the assistance of the Executive’s counsel if the Executive so desires). No act, nor
failure to act, on the Executive’s part will be considered intentional unless the Executive has acted, or failed to act, with a lack of good faith and with a lack of reasonable belief that the Executive’s action or failure to act was in or
not opposed to the best interests of the Company. 
 “Change in Control” means any following events: 
 (a) An acquisition (other than directly from the Company) of any voting securities of the Company by any Person who immediately after such
acquisition is the Beneficial Owner of 40% or more of the combined voting power of the Company’s then outstanding voting securities; provided that in determining whether a Change in Control has occurred, voting securities which are acquired by

under the Securities Exchange Act, is permitted to, and actually does, report its beneficial ownership of voting securities of the Company on Schedule 

  

 2 








 
13G (or any successor Schedule) (a “13G Filer”) (provided that, if any 13G Filer subsequently becomes required to or does report its
Beneficial Ownership of voting securities of the Company on Schedule 13D (or any successor Schedule) then such Person shall be deemed to have first acquired, on the first date on which such Person becomes required to or does so file, Beneficial
Ownership of all voting securities of the Company Beneficially Owned by it on such date, (iv) any Person in connection with a Non-Control Transaction (as hereinafter defined) or (v) any acquisition by an underwriter temporarily holding
Company securities pursuant to an offering of such securities, will not constitute an acquisition which results in a Change in Control; 
 (b) Consummation of: 
 (i) a merger, consolidation or reorganization involving the Company,
or any direct or indirect Subsidiary of the Company, unless: 
 (A) the stockholders of the Company immediately before such
merger, consolidation or reorganization will own, directly or indirectly, immediately following such merger, consolidation or reorganization, at least 50% of the combined voting power of the outstanding voting securities of the corporation resulting
from such merger, consolidation or reorganization (the “Surviving Corporation”) or any parent thereof in substantially the same proportion as their ownership of the voting securities of the Company immediately before such merger,
consolidation or reorganization; 
 (B) the individuals who were members of the Board immediately prior to the execution of
the agreement providing for such merger, consolidation or reorganization constitute a majority of the members of the board of directors of the Surviving Corporation (or parent thereof); and 
 (C) no Person (other than the Company, any Subsidiary of the Company, any employee benefit plan (or any trust forming a part thereof)
maintained by the Company, any Schedule 13G Filer, the Surviving Corporation, any Subsidiary or parent of the Surviving Corporation, or any Person who, immediately prior to such merger, consolidation or reorganization, was the Beneficial Owner of
40% or more of the then outstanding 

  

 3 








 
voting securities of the Company) is the Beneficial Owner of 40% or more of the combined voting power of the Surviving Corporation’s then outstanding
voting securities. 
 (D) a transaction described in clauses (A) through (C) above is referred to herein as a
“Non-Control Transaction”; or 
 (ii) the complete liquidation or dissolution of the company. 
 (iii) a sale or other disposition of all or substantially all of the assets of the Company to an entity (other than to an entity
(A) of which at least 50% of the combined voting power of the outstanding voting securities are owned, directly or indirectly, by stockholders of the Company in substantially the same proportion as their ownership of the voting securities of
the Company, (B) a majority if the board of directors of which is comprised of the individuals who were members of the Board immediately prior to the execution of the agreement providing for such sale or disposition and (C) of which no
Person (other than the Company, any Subsidiary of the Company, any employee benefit plan (or any trust forming a part thereof) maintained by the Company or any of its Subsidiaries, any Schedule 13G Filer, the Surviving Corporation, any Subsidiary or
parent of the Surviving Corporation, or any Person who, immediately prior to such merger, consolidation or reorganization, was the Beneficial Owner of 40% or more of the then outstanding voting securities of the Company) has Beneficial Ownership of
40% or more of the combined voting power of the entity’s outstanding voting securities. 
 (c) Individuals who, as of the
date hereof, constitute the Board (the “Incumbent Board”), cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the date first written above
whose election, or nomination for election by Company stockholders, was approved by a vote of two-thirds of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, unless
any such individual’s initial assumption of office occurs as a result of either an actual or threatened election contest (including, but not limited to, a consent solicitation). 
  

 4 








 (d) Notwithstanding the foregoing, a Change in Control will not be deemed to occur solely
because any Person (a “Subject Person”) acquires Beneficial Ownership of more than the permitted amount of the outstanding voting securities of the Company as a result of the acquisition of voting securities by the Company which, by
reducing the number of voting securities outstanding, increases the proportional number of shares Beneficially Owned by the Subject Person, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the
acquisition of voting securities by the Company, and after such share acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional voting securities which increases the percentage of the then outstanding voting
securities Beneficially Owned by the Subject Person, then a Change in Control will be deemed to have occurred. 
 (e)
Notwithstanding anything contained in this Agreement to the contrary, if the Executive’s employment with the Company is terminated prior to a Change in Control and the Executive reasonably demonstrates that such termination (i) was at the
request of a Person who has indicated an intention or taken steps reasonably calculated to effect a Change in Control or (ii) otherwise occurred in connection with, or in anticipation of, a Change in Control, then for all purposes of this
Agreement, the date of such Change in Control with respect to the Executive will mean the date immediately prior to the date of such termination of the Executive’s employment.

terminated (i) by the Company for Cause or Disability, (ii) by reason of the Executive’s death or (iii) by the Executive other than for Good Reason and other than during the 60-day period commencing on the first anniversary of

referred to in clauses (A) and (B) above. The Company’s obligation hereunder with respect to the foregoing benefits will be limited to the extent that the Executive obtains any such benefits pursuant to a subsequent employer’s
benefit plans, in which case the Company may reduce the coverage of any benefits it is required to provide the Executive hereunder as long as the coverages and benefits of the combined benefit plans are no less favorable to the Executive than the
coverages and benefits required to be provided hereunder. This Section 3.1(b) will not be interpreted so as to limit any benefits to which the Executive or the Executive’s dependents or beneficiaries may be entitled under any of the
Company’s employee benefit plans, programs or practices following the Executive’s termination of employment, including retiree medical and life insurance benefits; 
  

 9 








 (iv) the Company will pay in a single payment an amount in cash equal to the excess of

Executive’s Base Salary and the Bonus Amount, (3) the Company had made employer contributions to each defined contribution plan in which the Executive was a participant at the Termination Date in an amount equal to the amount of such
contribution for the plan year immediately preceding the Termination Date and (4) the Executive had been fully vested in the Executive’s benefit under each retirement plan in which the Executive was a participant, over (B) the lump
sum actuarial equivalent of the aggregate retirement benefit the Executive is actually entitled to receive under such retirement plans; 
 (v) the Company shall credit the Executive with [18 – 36] months of additional age and service credit for purposes of qualifying for any post-retirement health or welfare benefits provided by the Company as in
effect immediately prior to the Termination Date or, if more favorable to the Executive, as in effect at the time of the Change in Control or at any time thereafter prior to the Termination Date; 
 (vi) the Company shall provide the Executive with outplacement services suitable to the Executive’s position for a period of 12
months or, if earlier, until the first acceptance by the Executive of an offer of employment; and 
 (vii) The Company shall
reimburse the Executive for financial counseling and tax planning service costs incurred within [12 – 36] months following the Termination Date; provided that the aggregate cost of such financial counseling and tax planning services shall not
exceed $10,000 in any calendar year. 
 (c) The amounts provided for in Section 3.1(a) and Sections 3.1(b)(i),
(ii) and (iv) will be paid in a single lump sum cash payment by the Company to the Executive within five days after the Termination Date. Notwithstanding anything to the contrary in this Agreement, to the extent required in order to avoid
accelerated taxation and/or tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Agreement 

  

 10 








 
during the six-month period immediately following the Executive’s termination of employment shall instead be paid on the first business day after the
date that is six months following the Executive’s “separation from service” within the meaning of Section 409A of the Code. Any amount the payment of which is delayed in accordance with the preceding sentence shall be paid with
interest at an annual rate equal to the prime rate (as determined by the Northern Trust Company of Chicago from time to time) from the date on which such amount would otherwise have been paid until the actual date of payment. 
 (d) The Executive will not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or
otherwise, and no such payment will be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment except as specifically provided in Section 3.1(b)(iii) and 3.1(b)(vi). 
 (e) Notwithstanding anything in this Agreement to the contrary, the Executive shall not be entitled to the payments or benefits provided
in this Section 3.1 until the Executive has incurred a “separation from service” under Section 409A of the Code. 
 3.2
The compensation to be paid to the Executive pursuant to Sections 3.1(a), 3.1(b)(i) and 3.1(b)(ii) of this Agreement will be in lieu of any similar severance or termination compensation to which the Executive may be entitled under any other Company
severance or termination agreement, plan, program, policy, practice or arrangement. With respect to any other compensation and benefit to be paid or provided to the Executive pursuant to this Section 3. The Executive’s entitlement
to any compensation or benefits of a type not provided in this Agreement will be determined in accordance with the Company’s employee benefit plans and other applicable programs, policies and practices as in effect from time to time.

 Section 4. Notice of Termination. Following a Change in Control, any purported termination of the Executive’s
employment by the Company will be communicated by a Notice of Termination to the Executive. For purposes of this Agreement, no such purported termination will be effective without such Notice of Termination. 
 Section 5. Excise Tax Payments. 
 5.1 In the event that any payment or benefit (within the meaning of Section 280G(b)(2) of the Code) to the Executive or for the Executive’s benefit paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise in connection with, or arising out of, the Executive’s employment with the Company or a change in ownership or effective control of the Company or of a substantial portion of its assets (a “Payment”),
would be subject to the excise tax imposed by Section 4999 of the Code, or any interest or penalties are incurred 

  

 11 








 
by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to
herein as the “Excise Tax”), then, subject to Section 5.3 below, the Executive will be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the Executive of
all taxes (including any interest or penalties imposed with respect to such taxes and the Excise Tax, other than interest and penalties imposed by reason of the Executive’s failure to file timely a tax return or pay taxes shown due on the
Executive’s return, and including any Excise Tax imposed upon the Gross-Up Payment), the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. 
 5.2 An initial determination as to whether a Gross-Up Payment is required pursuant to this Agreement and the amount of such Gross-Up Payment will be
made at the Company’s expense by an accounting firm of recognized national standing selected by the Company and reasonably acceptable to the Executive (the “Accounting Firm”). The Accounting Firm will provide its determination
(the “Determination”), together with detailed supporting calculations and documentation, to the Company and the Executive within five days of the Termination Date, if applicable, or such other time as requested by the Company or by
the Executive (provided the Executive reasonably believes that any of the Payments may be subject to the Excise Tax). If the Accounting Firm determines that no Excise Tax is payable by the Executive with respect to a Payment or Payments, it will
furnish the Executive with an opinion reasonably acceptable to the Executive that no Excise Tax will be imposed with respect to any such Payment or Payments. Within ten days of the delivery of the Determination to the Executive, the Executive will
have the right to dispute the Determination (the “Dispute”). The Gross-Up Payment, if any, will be paid by the Company to the Executive within five days of the receipt of the Determination. The existence of the Dispute will not in any way
affect the Executive’s right to receive the Gross-Up Payment in accordance with the Determination. If there is no Dispute, the Determination will be binding, final and conclusive upon the Company and the Executive, subject to the application of
Section 5.4. 
 5.3 Notwithstanding the foregoing provisions of this Section 5, if it shall be determined that any Payment would be
subject to the Excise Tax, but the aggregate Payments do not exceed by at least $50,000 the greatest amount (the “Reduced Amount”) that could be paid to the Executive such that the receipt of the aggregate Payments would not give
rise to any Excise Tax, then no Gross-Up Payment shall be made to the Executive and the aggregate Payments shall be reduced to the Reduced Amount. The Executive shall be entitled to determine which Payments shall be reduced. 
 5.4 As a result of uncertainty in the application of Sections 280G and 4999 of the Code, it is possible that a Gross-Up Payment (or a portion thereof)
will be paid which should not be paid (an “Excess Payment”), a Gross-Up Payment (or a portion thereof) which should be paid will not be paid (an “Underpayment”) or that a portion of the Reduced Amount will be
subject to Excise Tax (an “Under Reduction”). 
 (a) An Underpayment will be deemed to have occurred
(i) upon notice (formal or informal) to the Executive from any governmental taxing authority that the Executive’s tax liability (whether in respect of the 

  

 12 








 
Executive’s current taxable year or in respect of any prior taxable year) may be increased by reason of the imposition of the Excise Tax on a Payment or
Payments with respect to which the Company has failed to make a sufficient Gross-Up Payment, (ii) upon a determination by a court, (iii) by reason of a determination by the Company (which will include the position taken by the Company,
together with its consolidated group, on its federal income tax return) or (iv) upon the resolution of the Dispute to the Executive’s satisfaction. If an Underpayment occurs, the Executive will promptly notify the Company and the Company
will promptly, but in any event at least five days prior to the date on which the applicable government taxing authority has requested payment, pay to the Executive an additional Gross-Up Payment equal to the amount of the Underpayment plus any
interest and penalties (other than interest and penalties imposed by reason of the Executive’s failure to file timely a tax return or pay taxes shown due on the Executive’s return) imposed on the Underpayment. 
 (b) An Excess Payment will deemed to have occurred upon a Final Determination (as hereinafter defined) that the Excise Tax will not be
imposed upon a Payment or Payments (or portion thereof) with respect to which the Executive had previously received a Gross-Up Payment. A “Final Determination” will be deemed to have occurred when the Executive has received from the
applicable government taxing authority a refund of taxes or other reduction in the Executive’s tax liability by reason of the Excess Payment and upon either (i) the date a determination is made by, or an agreement is entered into with, the
applicable governmental taxing authority which finally and conclusively binds the Executive and such taxing authority, or in the event that a claim is brought before a court of competent jurisdiction, the date upon which a final determination has
been made by such court and either all appeals have been taken and finally resolved or the time for all appeals has expired or (ii) the statute of limitations with respect to the Executive’s applicable tax return has expired. 

(c) An Under Reduction will be deemed to have occurred (i) upon notice (formal or informal) to the Executive from any governmental
taxing authority that the Executive’s tax liability (whether in respect of the Executive’s current taxable year or in respect of any prior taxable year) may be increased by reason of the imposition of the Excise Tax in respect of a
Payment, (ii) upon a determination by a court that Excise Tax is due in respect of an Payment, or (iii) by reason of a determination by the Company (which will include the position taken by the Company, together with its consolidated
group, on its federal income tax return) that it must withhold Excise Tax in respect of a Payment. The Executive will promptly notify the Company of any assertion of an Under Reduction of which the Company does not have knowledge. If an Under
Reduction is determined to have occurred, then, if a repayment by the Executive to the Company would result in (x) no portion of the remaining aggregate Payments being 

  

 13 








 
subject to the Excise Tax and (y) a dollar-for-dollar reduction in the Executive’s taxable income and wages for purposes of federal, state and
local income and employment taxes, the Executive shall repay the Company upon demand an amount (the “Under Reduction Amount”) equal to the amount of the aggregate Payments made to the Executive in excess of the amount which is
subsequently determined to be the greatest amount of aggregate Payments that could be paid to the Executive such that the receipt of the aggregate Payments would not give rise to any Excise Tax. 
 (d) If an Excess Payment or Under Reduction is determined to have been made, the Executive will pay to the Company on demand (but not less
than 10 days after the determination of such Excess Payment or Under Reduction and written notice has been delivered to the Executive) the amount of the Excess Payment or Under Reduction Amount plus interest at an annual rate equal to the Applicable
Federal Rate provided for in Section 1274(d) of the Code (the “Interest”) from the date such payment was made until the date of repayment to the Company. The Executive will use reasonable cooperative efforts at the request of
the Company to assist in the determination of the amount of the Executive’s Excess Payment, Underpayment or Under Reduction Amount. 
 5.5 Notwithstanding anything contained in this Agreement to the contrary, in the event that, according to the Determination, an Excise Tax is imposed on any Payment or Payments, the Company will pay to the applicable government taxing
authorities as Excise Tax withholding the amount of the Excise Tax that the Company has actually withheld from the Payment or Payments.

modification or discharge is agreed to in writing and signed by the Executive and the Company. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement
to be performed by such other party will be 

  

 15 








 
deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreement or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.

Control. 
 Section 16. Section 409A. The intent of the parties is that payments and benefits under this Agreement comply
with Section 409A of the Code to the extent subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered to be in compliance therewith. Notwithstanding anything contained herein to the
contrary, the Executive shall not be considered to have terminated employment with the Company for purposes of this Agreement until the Executive would be considered to have incurred a “separation from service” from the Company within the
meaning of Section 409A of the Code. To the extent required to avoid an accelerated or additional tax under Section 409A of the Code, amounts reimbursable to Executive under this Agreement shall be paid to the Executive on or before the
last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in-kind benefits provided to the Executive) during any one year may not effect amounts reimbursable or provided in
any subsequent year.
