 ARTICLE I 

INTRODUCTION & PLAN HISTORY 

1.01 Introduction. The General Dynamics Corporation 401(k) Plan 3.5 (As Adopted Effective as of January 1, 2016) (the
“Plan”) is maintained by General Dynamics Corporation (the “Company”), a Delaware Corporation. The purposes of the Plan are to encourage thrift on the part of eligible employees by furnishing them with an incentive to save for
the future and to give them an opportunity to become more interested in the affairs of the Company through investing in the General Dynamics Stock Fund. The Plan is intended to be a profit sharing plan with a Code Section 401(k) feature and a
Code Section 401(m) feature. A portion of the General Dynamics Stock Fund is designated as a stock bonus plan and an employee stock ownership plan (“ESOP”), as defined in Code Section 4975(e)(7). In the event that any provision
of the Plan relating to the ESOP conflicts with any applicable ESOP requirements set forth in the Code or any regulations thereunder, the Plan shall be construed and administered to conform to such requirements. The Plan is intended to be a safe
harbor plan under Code Section 401(k)(12) with a qualified automatic contribution arrangement under Code Section 401(k)(13). 

1.02 History and Effective Date. This Plan is established effective as of January 1, 2016. Certain of the balances subject to the
terms of the Plan were transferred on the Effective Date, either from the General Dynamics Corporation 401(k) Plan 3.0, which received a favorable determination letter issued by the Internal Revenue Service on September 20, 2013, or from the
General Dynamics Corporation 401(k) Plan 4.5, which received a favorable determination letter issued by the Internal Revenue Service on September 23, 2013. On the Effective Date, the Arma 401(k) Employee Savings Plan, a prototype plan which
received a favorable determination letter issued by the Internal Revenue Service on March 31, 2008, shall be merged into the Plan. 

1.03 Employers. Any subsidiary, affiliate or business unit of the Company that is a member of the Affiliated Group may become an
Employer with the Company’s consent, provided such consent is indicated by amendment to the Plan. Notwithstanding anything to the contrary, employees of any subsidiary, affiliate or business unit that become employees of the Company or of its
controlled group of corporations (as defined in Code Section 414(b)) by reason of any acquisition, merger or other corporate transaction shall not be permitted to participate in the Plan (a) in the absence of any express provision for
their participation in any Supplement (as defined herein) or (b) in the event that such employees continue to actively participate in any similar plan for which the Company or any of its affiliates, subsidiaries or business units assumes or
maintains sponsorship. A “subsidiary” of the Company is any legal entity of which more than 50 percent of the voting stock, units or other ownership interests thereof is owned, directly or indirectly, by the Company. An
“affiliate” of the Company is any legal entity of which more than 50 percent of the voting stock, units or other ownership interests thereof is owned, directly or indirectly, by the owner or owners of more than 50 percent of the voting
stock of the Company. A “business unit” of the Company is any subsidiary or affiliate of the Company or any economic or organizational or locational division or unit thereof. The Company and any stand-alone subsidiaries, affiliates or
business units of the Company which participate in the Plan are referred to below collectively as the “Employers” or “Employing Units” and sometimes individually as an “Employer” or an “Employing Unit.”

 1.04 Notices. Any notice or document required to be given to or filed with the Company
will be properly given or filed if delivered or mailed, by registered mail, postage prepaid, to the Company, at the address provided from time to time in the summary plan description or any summary of material modifications thereto. 

1.05 Funding of Benefits. Funds contributed under the Plan are held and invested in a trust fund (the “Trust Fund”), until
distribution, by a trustee appointed by the Company or the Investment Committee (the “Trustee”) in accordance with the terms of a trust agreement between the Investment Committee and/or the Company on the one hand, and the Trustee on the
other which implements and forms a part of the Plan (the “Trust Agreement”). Participation and benefits under the Plan are subject to the terms and provisions of the Plan and the Trust Agreement. 

1.06 Exhibits and Plan Supplements. From time to time, the Company may adopt exhibits to the Plan for the purpose of setting forth
specific provisions of this Plan (“Exhibits”). In addition, the Company may from time to time adopt supplements to this Plan document for the purpose of providing documentation necessary to determine benefits under the Plan for certain
employee groups and Employing Units (“Supplements”). An Exhibit or Supplement may provide for additional benefits, substitute one benefit for another or provide for more restrictive benefits than those found in the main body of this Plan
document. Exhibits and Supplements may also include provisions to preserve benefits attributable to such Employees’ participation in a plan of the Employing Unit, predecessor of the Employing Unit or Affiliated Group, or to coordinate such
benefits with the benefits of the Plan. Each such Exhibit or Supplement shall be attached to and form a part of the Plan. Each Exhibit and Supplement shall specify the Employing Unit to which it applies and shall supersede the provisions of the Plan
document to the extent necessary to eliminate any inconsistencies between the Plan document and such Exhibits and Supplements. 
 ARTICLE
II  
 DEFINITIONS 

The following words and phrases shall have the respective meanings stated below unless a different meaning is plainly required by the context:

 2.01 Account. “Account” means the recordkeeping account to which Contributions are credited under this Plan, including
amounts transferred into this Plan, as described in Article IX. An Account may be divided into various sub-accounts, as determined by the Plan Administrator. Such Accounts and subaccounts, if any, are referred to herein collectively as the
“Account” or “Accounts,” and sometimes individually as the “Account.” To the extent necessary or desirable as determined by the Plan Administrator, each Account shall segregate income from contributions for the purpose
of properly recording distributions and/or withdrawals from the Participant’s Account.

 2.02 Active Participant. “Active Participant” shall have the meaning set forth
in Section 3.02.

in Code Section 414(c)) with the Company; any organization (whether or not incorporated) which is a Participant of an affiliated service group (as defined in Code Section 414(m)) which includes the Company; and any other entity required to
be aggregated with the Company pursuant to Regulations under Code Section 414(o) (collectively referred to herein as an “Affiliated Group Member”). 

2.04 After-Tax Contributions. “After-Tax Contributions” means the amount, if any, withheld from the Participant’s
paycheck on a non-deductible basis and contributed to the Plan as permitted under a specific provision of the Plan. 
 2.05 Authorized

maternity or paternity reasons, or any other reason. An Authorized Leave of Absence shall include that portion of leave under the Family and Medical Leave Act, as amended (the “FMLA”) that is required to be credited by the FMLA. In
addition, the following shall be Authorized Leaves of Absence: 
  

	 	(a)	Armed Forces Leave. An absence due to service in the Armed Forces of the United States shall be considered an Authorized Leave of Absence provided that the Employee returns to employment with the Employer with
re-employment rights provided by federal law. 

  

	 	(b)	Maternity or Paternity Leave of Absence. For purposes of this Plan, a “maternity or paternity leave of absence” means an absence from work for any period by reason of the Employee’s pregnancy,
birth of the Employee’s child, placement of a child with the Employee in connection with the adoption of such child, or any absence for the purpose of caring for such child for a period immediately following such birth or placement. In the case
of such an absence, the 12-consecutive-month period beginning on the first anniversary of the first day of such absence shall not constitute a One-Year Break-in-Service under Section 7.02(f). The Plan Administrator shall determine, under rules
of uniform application and based on information provided to the Plan Administrator by the Employee, whether the Employee’s absence from work is due to “maternity or paternity leave of absence.”

 3 








 2.07 Company. “Company” means General Dynamics Corporation and any successor

 2.08 Company Stock or Shares. “Company Stock” or “Shares” means “qualifying employer
securities” of the Company as that term is defined in Code Section 4975(e)(8) (with reference to Code Section 409(l)(1)) to mean common stock issued by the Company which is readily tradable on an established securities market. 

2.09 Continuous Service. “Continuous Service” has the meaning described in Section 7.02(d). 

2.10 Contributions. “Contributions” means any 401(k) Contributions, Roth Elective Deferrals, After-Tax Contributions,

 2.11 Deferral
Pay. “Deferral Pay” (also known as “401(k) Eligible Pay”) means an Eligible Employee’s base pay or base rate of pay during such periods he or she is eligible to participate in the Plan, as reported by the Employing Unit,
prior to any reduction for 401(k) Contributions, and prior to any reduction for deferrals of regular salary under any other plan of deferred compensation or any flexible benefits, healthcare/dependent care spending accounts or cafeteria plan

(provided that these payments are related to hours worked), vacation, sick and/or holiday pay, accrued vacation, sick and/or holiday pay paid after termination of employment that the Eligible Employee could have received if employment had continued,
cash payments provided in lieu of fringe benefits intended to satisfy prevailing wage obligations under the Service Contract Act, and cash bonuses such as business unit and executive compensation awards, performance awards or spot bonus awards

determine to be not related to the performance of personal services. No compensation shall be included as Deferral Pay pursuant to the preceding sentence unless reflected in an amendment to the Plan. For Plan Years commencing on or after
January 1, 2016, Deferral Pay shall not include annual compensation in excess of $265,000 per year, or such other amount, as adjusted for cost-of-living increases as may be determined under Code Section 401(a)(17) or any successor
provision thereto. 

  
 4 








 2.12 Disability. “Disability” means when the Plan Administrator is notified by
the Employing Unit that a Participant is determined to be disabled under the terms of his or her Employing Unit’s applicable long-term disability plan or when a Participant is determined to be disabled by the Social Security Administration. An
individual who elects an installment form of distribution of his or her Vested Account by reason of Disability may be required to submit to a medical examination at any time by the Plan Administrator, but not more often than once every six
(6) months, to determine whether he or she is eligible for continuance of further installment payments. If the Plan Administrator is notified by the Employing Unit that such individual prior to attaining age sixty-five (65) is no longer
disabled under the terms of his or her Employing Unit’s applicable long-term disability plan or is no longer found to be disabled by the Social Security Administration and such individual returns to active status with the Company, the
distribution of his or her Vested Account shall cease. In the event that such individual shall fail within thirty (30) days after receiving notice to submit to medical examinations, his or her installment distribution payments may be
discontinued at the discretion of the Plan Administrator until he or she has submitted to such examination, after which his or her continued eligibility may be determined as provided above. The medical examinations provided herein shall be made by a
competent physician or physicians or clinic or hospital selected by the Plan Administrator. 
 2.13 Effective Date. “Effective
Date” shall have the meaning set forth in Section 1.02.

ARTICLE III 

PARTICIPATION 

3.01 Eligibility and Commencement of Participation. The Plan includes a qualified automatic contribution arrangement (within the
meaning of Code Section 401(k)(13)) and the following provisions shall apply to a new Eligible Employee: 
  

	 	(a)	 Each Employee who becomes an Eligible Employee as a result of transferring into the Plan on January 1, 2016, and who has not made an election
under his or her transferor plan to contribute at least 6% shall (i) if contributing zero, be automatically enrolled with 6% of his or her Deferral 



  
 8 









	 	
Pay contributed on a before-tax basis, or (ii) if contributing an amount greater than zero and less than 6%, be automatically increased, with the increased contributions made on a before-tax
basis, so that 6% of his or her Deferral Pay is contributed; in each case, unless an affirmative election is made to the contrary. An Eligible Employee who is hired or rehired on or after January 1, 2016, or whose eligibility for the Plan on or
after January 1, 2016 results from an employment transfer from an Affiliated Group Member is immediately eligible and shall automatically have 6% of his or her Deferral Pay contributed on a before-tax basis, unless an affirmative election is
made to the contrary. 

  

	 	(b)	Any such automatic enrollment under Section 3.01(a) shall be effective within a reasonable period of time, as determined by the Plan Administrator, after which the notice described in Section 3.01(c) below is
provided, which shall be no later than the earlier of (i) the pay date for the second pay period that begins after such notice is provided, or (ii) the first pay date that occurs at least 30 days after such notice is provided.


  

	 	(c)	Each Eligible Employee described in Section 3.01(a) above shall be provided a notice which explains the Employee’s rights with respect to the automatic enrollment, including information about the level of
401(k) Contributions which will be made on the Employee’s behalf if the Eligible Employee does not make an affirmative election to the contrary, the Employee’s right to elect not to have such automatic 401(k) Contributions made on the
Employee’s behalf (or to elect to have such 401(k) Contributions made in a different amount), how the automatic contributions made pursuant to this Section 3.01 will be invested in the absence of an affirmative investment election, and
such other information as is required by applicable regulations. Such notice shall be provided in sufficient time to allow the Employee a reasonable period of time after receipt of such notice and before the first 401(k) Contribution is made
pursuant to this Section 3.01 in order to make an affirmative election to the contrary. Such notice shall also be provided to each Eligible Employee within a reasonable period of time before the first day of each Plan Year (which is deemed
satisfied if such notice is provided at least 30 days and no more than 90 days before the beginning of each Plan Year). 

  

	 	(d)	Any such automatic enrollment contribution made pursuant to this Section 3.01 shall cease to apply if an Eligible Employee makes an affirmative election either not to have 401(k) Contributions made to the Plan on
his or her behalf or to have such contributions made to the Plan at a different rate specified by the Employee. Such affirmative election shall be effective, in accordance with uniform procedures established by the Plan Administrator, as soon as
practicable after it is made, but in no event retroactively. 


  
 9 









	 	(e)	Subject to the limits of Article IV, and effective as of the date determined by the Plan Administrator, the Plan Administrator may increase the automatic contribution provided for by this Section 3.01 in accordance
with any rules established and communicated by the Plan Administrator. 

 Any other Eligible Employee not described in Section 3.01(a)
above may elect to participate in the Plan by complying with enrollment procedures and authorizing a deferral of Deferral Pay at such time and in such manner as the Company may prescribe. Each such Eligible Employee shall become a Participant in the
Plan as soon as administratively feasible after electing enrollment and complying with enrollment procedures. The Plan Administrator will furnish each such Participant and each beneficiary receiving benefits thereunder with a copy of a summary plan
description. 
 3.02 Active Participation. A Participant who is eligible to make 401(k) Contributions (regardless of whether such
contributions are actually made) or whose right to do so has been temporarily suspended for any reason, and who has an Account balance under the Plan, is an Active Participant and is eligible to receive contributions under Article V. Each
Participant shall participate in the Plan under the terms and conditions of the Supplement applicable to that Participant’s current Employing Unit. 

3.03 Inactive Participation. A Participant shall be an Inactive Participant when he is no longer an Eligible Employee but maintains an
Account balance. An Inactive Participant is not eligible to make a 401(k) Contributions election, nor may he receive contributions under Article V, but he may continue to make investment transfer and distribution decisions, as provided for by
the Plan. Where the context permits, Inactive Participants and Active Participants are referred to collectively as “Participants.” 

3.04 Limited Participation by Beneficiary or Alternate Payee. If a Participant dies before his or her Account balance is reduced to
zero, his or her Beneficiary shall be deemed a Participant for the limited and exclusive purposes of administering the deceased Participant’s Account and distributing the same. Any “Alternate Payee” identified in a Qualified Domestic
Relations Order (as defined by Section 414(p) of the Code) shall be deemed a Participant for the limited and exclusive purposes of administering the Alternate Payee’s interest in the Plan and distributing the same. 

3.05 Termination of Participation. An individual who has become a Participant shall remain an Active Participant or an Inactive
Participant, as appropriate, until he or she dies or his or her Account balance is reduced to zero. 
 3.06 Transfer of Employment.
Any change in employment status which causes a Participant who remains employed by the Affiliated Group to cease to be an Eligible Employee shall not be considered to be a termination of employment for purposes of Section 7.02(e), but such
Participant shall cease to be an Active Participant and shall become an Inactive Participant. Any transfer from one Affiliated Group Member to another will not be treated as a termination of employment for purposes of Section 7.02(e) of this
Plan. In the event of any such transfers between different Supplements in the Plan, or any such transfer between the Plan and an Other General Dynamics Corporation 401(k) Plan, such Participant and his or her Contributions,


  
 10 








 
prospectively from the date of any such transfer, will cease to be governed by his or her prior Supplement and will be governed by the terms of his or her new Supplement in the Plan or in the
Other General Dynamics Corporation 401(k) Plan in the event such Participant contributes to any such plan. In the event of any such transfers between different Supplements within the Plan, any contribution and investment elections under the prior
Supplement will apply in the new Supplement until changed by the Participant if the applicable contribution rate structures and investment options, both before and after any such transfer, are the same. In the event of any such transfers between the
Plan and one of the Other General Dynamics Corporation 401(k) Plans, and unless otherwise provided by the Plan Administrator, the contribution and investment elections under this Plan will not apply in the Other General Dynamics Corporation 401(k)
Plan, and such Other General Dynamics Corporation 401(k) Plan’s rules with respect to enrollment shall apply. If such a transfer occurs between the Plan and one of the Other General Dynamics Corporation 401(k) Plan, the Participant’s
Account shall be transferred as soon as administratively practical following the date of the Participant’s transfer, in accordance with rules established by the Plan Administrator. 

3.07 Leased Employees. A “leased employee” shall not be eligible to participate in the Plan. Consistent with Code
Section 414(n), a “leased employee” means any person who has provided services for an Employing Unit under primary direction of or control by the Employing Unit, on a substantially full time basis for a period of at least one year,
pursuant to an agreement between the Employing Unit and a leasing organization. The period during which a leased employee performs services for the Employing Unit shall be taken into account for purposes of participation or service if such leased
employee becomes an Eligible Employee, unless (i) such leased employee is a participant in a money purchase pension plan maintained by the leasing organization which provides a non-integrated employer contribution rate of at least 10 percent of
compensation, immediate participation for all employees and full and immediate vesting, and (ii) leased employees do not constitute more than 20 percent of the Employing Unit’s non-highly compensated workforce. 

ARTICLE IV 

PARTICIPANT CONTRIBUTIONS 

4.01 401(k) Contributions. Subject to the limitations of this Article IV and the remainder of the Plan, each Eligible Employee who
becomes a Participant in the Plan pursuant to the automatic enrollment provisions of Section 3.01 of the Plan shall automatically have 6% of his or her Deferral Pay contributed on a before-tax basis to the Plan, unless an affirmative election
to the contrary is made, in accordance with Section 3.01. In accordance with any rules established by the Plan Administrator, such Participant may subsequently change such deferral percentage. Subject to the foregoing, all other Participants
may elect to make 401(k) Contributions under the Plan for any Plan Year, beginning with the Plan Year in which he or she becomes a Participant, as provided for in the applicable Supplement. Each election made by a Participant under this
Section 4.01 must be made at such time and in such manner as the Plan Administrator shall determine. 
 4.02 Payment of Participant
Contributions. A Participant’s 401(k) Contributions, Roth Elective Deferrals, and After-Tax Contributions, as applicable, shall be 

  
 11 








 
made by the Employing Unit on behalf of the Participant, and shall reduce the Participant’s compensation at the time of payment of such compensation. Amounts so deducted (or amounts by which
a Participant’s compensation has been so reduced) for any calendar month shall be paid to the Trustee as soon as practicable thereafter, but in any event no later than the 15th business day of the next following month, subject to permissible
extensions. 
 4.03 After-Tax Contributions. After-Tax Contributions shall be permitted under the Plan only as set forth in the
applicable Supplement. 
 4.04 Variation, Discontinuance and Resumption of Participant Contributions. A Participant may elect to
change his or her deferral percentage (but not retroactively) within the limits specified in this Article IV, to discontinue contributions or to resume contributions. Each such election by a Participant shall be made at such time and in such manner
as the Plan Administrator shall determine, and shall be effective only in accordance with such rules as shall be established from time to time by the Plan Administrator. 

4.05 Maximum Amount of Participant Contributions. In no event shall the amount of a Participant’s elective deferrals
(401(k) Contributions and Roth Elective Deferrals) for any calendar year exceed $18,000 (for Plan Years commencing on or after January 1, 2016, or such other amount as may be determined under Code Section 402(g) for that calendar
year). If, because of the foregoing limitation, a portion of the contributions made by a Participant may not be credited to his or her Account for a calendar year, such portion and the earnings thereon shall be distributed to the Participant by
April 15 of the following calendar year (subject to permissible extensions). The earnings distributed to Participants pursuant to the preceding sentence shall not include earnings for the gap period. To the extent there is an excess
distribution to a Participant, and such Participant does not actively elect a method of receiving such excess, distributions will first come from Roth Elective Deferrals and then 401(k) Contributions. 

4.06 Rollover Contributions. At the direction of the Plan Administrator, and in accordance with such rules as the Plan Administrator
may establish from time to time, rollovers described in Section 402(c) of the Code, rollover contributions described in Section 408(d)(3) of the Code and benefits of an Employee under another plan that meets the requirements of
Section 401(a) of the Code may be received by the Trustee in cash only, and will be credited to an account established in the name of the Employee (provided he or she is eligible to be an Active Participant under this Plan). 

Additionally, at the direction of the Plan Administrator and in accordance with such rules as the Plan Administrator may establish from time to time, the Plan
will accept only in cash on behalf of an Active Participant: 
  

	 	(a)	 a direct rollover of an eligible rollover distribution from: (i) another plan that meets the requirements of Sections 401(a) or 403(a) of
the Code (excluding after-tax employee contributions, unless (if permitted by the Plan Administrator) such contributions are separately accounted for and relate to corporate acquisitions or the integration of acquired plans’ assets into the
Plan); or (ii) an annuity contract described in Section 403(b) of the 



  
 12 









	 	
Code (excluding after-tax employee contributions); or (iii) an eligible plan under Section 457 of the Code which is maintained by a state, political subdivision of a state, or an agency
or instrumentality of a state or political subdivision of a state; 

  

	 	(b)	a Participant contribution of an eligible rollover distribution from: (i) another plan that meets the requirements of Sections 401(a) or 403(a) of the Code (excluding after-tax employee contributions, unless
(if permitted by the Plan Administrator) such contributions are separately accounted for and relate to corporate acquisitions or the integration of acquired plans’ assets into the Plan); or (ii) an annuity contract described in
Section 403(b) of the Code (excluding after-tax employee contributions); or (iii) an eligible plan under Section 457 of the Code which is maintained by a state, political subdivision of a state, or an agency or instrumentality of a
state or political subdivision of a state; and 

  

	 	(c)	a Participant rollover contribution of the portion of a distribution from an individual retirement account or annuity described in Sections 408(a) or 408(b) of the Code that is eligible to be rolled over and would
otherwise be includible in gross income. 

 Any amounts received by the Trustee for a Participant in accordance with any of the preceding
provisions shall be adjusted from time to time in accordance with Article IX of the Plan and shall be fully vested in the Employee for whom it is held under the Plan. 

4.07 Vesting. A Participant shall always be 100% vested in the amounts (including earnings) attributable to any 401(k) Contributions,
Roth Elective Deferrals, After-Tax Contributions, Rollover Contributions, catch-up contributions described in Section 4.08, and safe harbor Employer Matching Contributions described in Section 5.01. Any dividends from investments in the
General Dynamics Stock Fund shall always be 100% vested to the extent the election contemplated by Section 8.14 of the Plan is permitted by the Plan Administrator. See Article VII for vesting rules affecting other types of Contributions.

 4.08 Catch-up Contributions. In accordance with, and subject to the limitations of, Section 414(v) of the Code, all
Participants who are eligible to make elective deferrals under the Plan and who have attained age 50 before the close of the Plan Year shall be eligible to make catch-up contributions. For purposes of the preceding sentence, a Participant who is
projected to attain age 50 before the end of a Plan Year shall be deemed to be age 50 as of January 1 of such year. Such catch-up contributions shall not be taken into account for purposes of the provisions of the Plan implementing the
requirements of Sections 401(k)(3), 401(k)(11), 401(k)(12), 410(b) or 416 of the Code, as applicable, by reason of the making of such catch-up contributions. Furthermore, the election to make such catch-up contributions shall be made in
accordance with such rules as determined by the Plan Administrator and, at the discretion of the Plan Administrator, may be made separately from all other contribution elections under the Plan. 

4.09 Amounts Limited. Notwithstanding anything to the contrary contained herein, to the extent permitted by the Company and applicable
law and pursuant to an unfunded 

  
 13 








 
deferred compensation plan established by the Company, amounts limited by applicable tax or Plan limitations may be credited to such unfunded deferred compensation plan, and amounts so
limited that may have been paid to the Plan may be returned to the Company. 
 4.10 Roth Elective Deferrals. 

 

	 	(a)	General Application. The Plan accepts Roth Elective Deferrals and Roth rollover contributions made on behalf of Participants under all applicable Supplements herein. A Participant’s Roth Elective Deferrals and Roth
rollover contributions will be allocated to separate accounts maintained for such funds as described in subsection (b). Unless specifically stated otherwise, Roth Elective Deferrals will be treated as 401(k) Contributions for all purposes under the
Plan in accordance with applicable law and as required by the context of the Plan. Additionally, Roth Elective Deferrals shall not be made under any automatic enrollment provisions of the Plan. 


 

	 	(b)	Separate Accounting. Contributions and withdrawals of Roth Elective Deferrals and rollovers (collectively, “Roth contributions”) will be credited and debited to the Roth Accounts (i.e., Roth Elective Deferral
Account and Roth Rollover Account) maintained for each Participant. The Plan will maintain a record of the amount of Roth contributions in each Participant’s Account. Gains, losses, and other credits or charges must be separately allocated on a
reasonable and consistent basis to each Participant’s Roth Accounts and the Participant’s other Accounts under the Plan. No contributions other than Roth Elective Deferrals and properly attributable earnings will be credited to each
Participant’s Roth Elective Deferral Account. Solely with respect to the order in which Accounts may be accessed and subject to any other restrictions contained in the Plan regarding the availability of funds for certain purposes, the depletion
order of Accounts for any applicable (as determined by the Plan Administrator) purposes under the Plan will be in accordance with rules established by the Plan Administrator from time to time. Roth contributions can be depleted separately from other
contribution sources. Roth contributions, earnings, distributions and withdrawals will be taxed in accordance with applicable law. 

  

	 	(c)	Direct Rollovers. Notwithstanding anything to the contrary, a direct rollover of a distribution from a Roth Elective Deferral Account under the Plan will only be made to another Roth elective deferral account under an
applicable retirement plan described in Section 402A(e)(1) of the Code or to a Roth IRA described in Section 408A of the Code, and only to the extent the rollover is permitted under the rules of Section 402(c) of the Code.
Notwithstanding Section 4.06, the Plan will accept a rollover contribution to a Roth Rollover Account only if it is a direct rollover from another Roth elective deferral account under an applicable retirement plan described in
Section 402A(e)(1) of the Code and only to the extent the rollover is permitted under the rules of Section 402(c) of the Code. Notwithstanding Section 4.06 of the Plan, the Plan will not accept rollovers from a Roth IRA.



  
 14 









	 	(d)	Correction of Excess Contributions. In the case of a distribution of excess contributions for a Highly Compensated Employee, distributions will first come from 401(k) Contributions and then Roth Elective Deferrals.


  

	 	(e)	In-Plan Roth Rollovers. In accordance with Code Section 402A(c)(4) and any regulatory guidance thereunder, an eligible rollover distribution made from the vested Account of an Active Participant (or a surviving
spouse Beneficiary or an alternate payee that is a spouse or former spouse) under the Plan other than a designated Roth Account, including from Accounts that are otherwise nondistributable, may be transferred to the Active Participant’s
designated Roth Account (or the designated Roth Account of a surviving spouse Beneficiary or an alternate payee that is a spouse or former spouse) under the Plan. The Plan will maintain such records as are necessary for the proper reporting of
in-plan Roth rollovers. 

 ARTICLE V 

EMPLOYER CONTRIBUTIONS 

5.01 Employer Matching Contributions. The Company shall make an “Employer Matching Contribution” to the Trustee equal to 100
percent on the first 1 percent of a Participant’s Deferral Pay contributed pursuant to Article IV and any applicable Supplement, and 50 percent on the next 5 percent of a Participant’s Deferral Pay contributed pursuant to Article IV and
any applicable Supplement. Such safe harbor Employer Matching Contributions will be made on 401(k) Contributions first, then Roth Elective Deferrals, and after which any applicable After-Tax Contributions will be subject to such Employer Matching
Contributions. Employer Matching Contributions may be made in cash or such other property as may be determined by the Company, and shall be invested in accordance with Article VI. Notwithstanding the foregoing, no Employer Contributions shall
be made in Company Stock during a period commencing with the public announcement of an offer for acquisition of the common stock of the Company (ending at the expiration of the offer period), as described in Article VI. Non-safe harbor
“Employer Matching Contributions” shall include such amounts, if any, that were made prior to January 1, 2016, to a non-safe harbor plan, and that were transferred to the Plan. 

The Company may make additional Employer Matching Contributions to the Accounts of Participants in accordance with such nondiscriminatory rules as it may
establish and communicate from time to time so that certain Participants are able to benefit from Employer Matching Contributions throughout any particular Plan Year, provided that such additional contributions do not exceed the maximum amounts
described in this Section 5.01 and the amount that such Participants would have received had their contributions been made throughout the duration of any particular Plan Year. 

5.02 Employer Discretionary Contribution. For each Plan Year, the Company, in its discretion, may specify (a) an aggregate
discretionary contribution to be made under the 

  
 15 








 
Plan for that year and (b) a definite basis or formula by which such aggregate discretionary contribution can be determined within a reasonable time after the end of that Plan Year, or
(c) any other type of Company contribution that is not necessarily based on the achievement or existence of any profits or actual 401(k) Contributions applicable for and described in any one or more Supplements. Any of the foregoing shall be
known as an “Employer Discretionary Contribution.” If any such Employer Discretionary Contribution is made, any Employees eligible to receive such contributions may receive, as specified in an applicable Supplement, a proportionate share
of such contributions based on an allocation formula that generally considers each eligible Employee’s actual base salary (or other compensation specified in the applicable Plan Supplement) over the total actual base salary (or other
compensation specified in the applicable Plan Supplement) of all Employees eligible to receive such contributions under the applicable Plan Supplement. In the event Employer Discretionary Contributions are made for any Plan Year, the Company, as
specified in a Supplement, shall contribute to the Trustee amounts determined by it which shall be allocated to the Accounts of Participants eligible for such contributions in accordance with the applicable Supplement. In addition to the foregoing,
the Company shall be permitted to make any such contributions on any basis determined by the Company that will permit passage of any discrimination or other testing. Notwithstanding the foregoing, the ESOP component of the Plan will not be used to
satisfy the requirements of IRC § 401(a)(4) by using cross-testing. 
 5.03 Limitations on Employer Contributions. The
Company’s total contribution for a Plan Year is conditioned on its deductibility under Section 404 of the Code in that year, shall comply with the contribution limitations set forth in Section 9.09 and the allocation limitations
contained in Section 9.10, and shall not exceed an amount equal to the maximum amount deductible on account thereof by the Company for that year for purposes of federal taxes on income. 

5.04 Payment of Employer Contributions. The Company’s total contribution under the Plan for any Plan Year shall be paid without
interest, not later than the time prescribed by law for filing the Company’s federal income tax return for such year, including extensions thereof. 

5.05 Verification of Employer Contributions. If for any reason the Company decides to verify the correctness of any amount or
calculation relating to any contribution for any Plan Year, the certificate of an independent accountant selected by the Company as to the correctness of any such amount or calculation shall be conclusive on all persons. 

5.06 No Interest in Employers. The Company shall have no right, title or interest in the Trust Fund, nor shall any part of the Trust
Fund revert or be repaid to the Company, directly or indirectly, unless: 
  

	 	(a)	the IRS initially determines that the Plan, as applied to the Company, does not meet the requirements of Section 401(a) of the Code, in which event the contributions made to the Plan by the Company shall be
returned to it within one year after such adverse determination; 


  
 16 









	 	(b)	a contribution is made by the Company by mistake of fact and such contribution is returned to it within one year after payment to the Trustee; or 


 

	 	(c)	a contribution conditioned on the deductibility thereof is disallowed as an expense for federal income tax purposes and such contribution (to the extent disallowed) is returned to the Company within one year after the
disallowance of the deduction. 

 Contributions may be returned to the Company pursuant to paragraph (a) above only if they are
conditioned upon initial qualification of the Plan, and an application for determination was made by the time prescribed by law for filing the Company’s federal income tax return for the taxable year in which the Plan was adopted (or such other
date as the Secretary of the Treasury may prescribe). The amount of any contribution that may be returned to the Company pursuant to paragraph (b) or (c) above must be reduced by any portion thereof previously distributed from the Trust
Fund and by any losses of the Trust Fund allocable thereto, and in no event may the return of such contribution cause any Participant’s Account balances to be less than the amount of such balances had the contribution not been made under the
Plan. 
 ARTICLE VI 

INVESTMENT OF CONTRIBUTIONS 

6.01 The Investment Funds. The Trust Fund as of any date shall consist of all property of every kind then held by the Trustee on behalf
of the Plan. The Trust Fund shall consist of such investment funds as the Investment Committee shall determine from time to time, except that the Trust Fund shall maintain a Company Stock fund (the “General Dynamics Stock Fund”), subject
to the terms of Section 6.11 below. The purpose of the General Dynamics Stock Fund is to enable Plan participants to indirectly invest in Company Stock through the Plan. 

A portion of the General Dynamics Stock Fund shall be an ESOP, as described in the following paragraph. The Trustee’s purchase of Company Stock for the
General Dynamics Stock Fund shall be made in accordance with this Section and Section 6.05 below. Pending investment, reinvestment or distribution as provided in the Plan, the Trustee may temporarily retain the assets of any one or more of
the investment funds in cash, commercial paper, short-term obligation, or undivided interests or participation in common or collective short-term investment funds. Any investment fund may be partially or entirely invested in any common or commingled
fund or in any group annuity, deposit administration or separate account contract issued by a legal reserve life insurance company which is invested generally in property of the kind specified for the investment fund. The Investment Committee, in
its discretion, may direct the Trustee to establish such investment funds or, subject to the requirement to maintain the General Dynamics Stock Fund, to terminate any of the investment funds as it shall from time to time consider appropriate and in
the best interests of the Participants. Subject to the requirement to maintain the General Dynamics Stock Fund and the terms of Section 6.11 below, the Investment Committee may change the types of investment funds offered, may add, freeze or
delete any particular investment fund, and may map investments between investment funds (or from investment funds of merged plans into investment funds of the Plan), in each case, other than as 

  
 17 








 
to the General Dynamics Stock Fund. The decision to invest in any particular investment fund offered under the Plan, however, is the sole responsibility of each Participant. The Trustee, the Plan
Administrator, the Investment Committee, the Company or any Employer, or any of its directors, officers, employees or agents are not empowered to advise a Participant as to the manner in which his Account shall be invested. The fact that a security
is available to Participants (or Beneficiaries) for investment under the Plan shall not be construed as a recommendation for the purchase of that security, nor shall the designation of any option impose any liability on the Company or any Employer,
or any of its directors, officers, employees or agents, the Trustee, the Investment Committee or the Plan Administrator. The funds established hereunder may be referred to collectively as the “investment funds” and individually as an
“investment fund.” 
 The General Dynamics Stock Fund shall be an ESOP to the extent the dividend election of Section 8.14 is available to
the assets held in the General Dynamics Stock Fund. All assets are eligible to be invested in the General Dynamics Stock Fund, except that any benefits or contributions that are integrated with Social Security will not be a part of the ESOP and
will not be eligible for the election described in Section 8.14. Notwithstanding anything to the contrary, all non-ESOP contributions to the General Dynamics Stock Fund shall be deemed “non-ESOP” for all average deferral
percentage testing and all aggregate contribution percentage testing purposes under the Plan. 
 6.02 Investment Fund Elections. The
Plan is intended to constitute a plan described in Section 404(c) of ERISA. Except as otherwise provided, a Participant may elect to invest all or a portion of his or her own contributions in his or her Account in one or more of the Plan’s
investment funds. Employer Contributions made on behalf of a Participant shall be invested in one or more of the Plan’s investment funds in accordance with the Participant’s allocation and percentage elections applicable to his or her
401(k) Contributions (or, if none, then After-Tax Contributions). Investment elections must be made in whole percentages, shall be made at such time and in such manner as the Plan Administrator shall determine, and shall be subject to any rules,
restrictions and limitations established by the Plan Administrator. If a Participant fails to make an election under this Section 6.02, with regard to his or her contributions (including all automatic deferrals described in Section 4.01 of
the Plan) and his or her share of the Employer Contributions, such Participant shall be deemed to have elected to have such contributions invested in the applicable default investment fund as shall be designated by the Investment Committee and
communicated to Participants from time to time by the Plan Administrator in accordance with any applicable laws. The Plan Administrator shall establish rules to permit investment fund elections consistent with Code Section 401(a)(28) and any
related Treasury regulations thereunder for ESOP diversification purposes under the Plan. 
 Unless otherwise provided in Section 8.14, dividends paid
on investments held in the General Dynamics Stock Fund shall be reinvested in that investment fund. 
 6.03 Investment Fund
Transfers. Subject to any administrative rules established by the Plan Administrator, a Participant may elect that all or a part of his or her interest in an investment fund shall be liquidated and the proceeds thereof transferred to one or more
of the other investment funds. Each such election may be made in either whole percentages or on a dollar specific basis. Transfers may be made at such time and in such 

  
 18 








 
manner as the Plan Administrator shall determine, and shall be subject to any rules, restrictions and limitations established by the Plan Administrator, including, but not limited to,
restrictions on and resulting penalties for excessive trading. 
 6.04 Diversification. The provisions of this Article VI are
intended to satisfy Code Section 401(a)(28) and the Pension Protection Act of 2006 (including, but not limited to, Code Section 401(a)(35) and the Treasury regulations promulgated thereunder) by permitting immediate diversification for all
units in the General Dynamics Stock Fund acquired by the Account of a Participant. 
 6.05 Purchase of Company Stock. As soon as
practicable after receipt of contributions applicable thereto, the Trustee shall regularly purchase Company Stock from time to time in the open market in accordance with a non-discretionary purchasing program, or shall purchase authorized but
unissued Company Stock from General Dynamics Corporation or Company Stock held in the treasury of General Dynamics Corporation. In the event that authorized but unissued or treasury Company Stock is purchased by the Trustee, the price per share
shall be the average closing market price of the Company Stock on the New York Stock Exchange over the five most recent days prior to such purchase on which at least one sale took place. Company Stock will be held in the name of the Trustee or its
nominees for the account of the Participants or Inactive Participants until distributed, and the Trustee shall in its discretion exercise or sell any rights for the purchase of any additional shares of Company Stock or other securities which General
Dynamics Corporation may offer to its shareholders, except as described in Section 6.06 below. 
 6.06 Voting of Company Stock.
When the Company prepares for any annual or special meeting, the Company shall notify the Trustee and the Stock Fund Fiduciary at least thirty (30) days in advance of the intended record date and shall cause a copy of all proxy solicitation
materials to be sent to the Trustee and the Stock Fund Fiduciary. If requested by either the Trustee or the Stock Fund Fiduciary, the Company shall certify to the requesting party that the aforementioned materials represent the same information
distributed to shareholders of Company Stock. Based on these materials, the Trustee and the Stock Fund Fiduciary shall prepare (or cause to be prepared) a voting instruction form and shall provide a copy of all proxy solicitation materials to be
sent to each Participant with an interest in the General Dynamics Stock Fund held in the Trust Fund, together with the foregoing voting instruction form to be returned to the Trustee or its designee. The form shall show the number of full and
fractional shares of Company Stock credited to the Participant’s Account. 
 Each Participant (or Beneficiary in the event of the death of the
Participant, or a representative properly designated by that Participant, or the Participant’s legal guardian) is, for purposes of this Section 6.06, hereby designated a “named fiduciary” within the meaning of
Section 402(a)(2) of ERISA, with respect to Company Stock allocated to his Account, and shall have the right to direct the Trustee as to the manner in which the Trustee is to vote (including not to vote) that number of shares of Company Stock
credited to his Account (both vested and unvested). Directions from a Participant to the Trustee concerning the voting of Company Stock shall be communicated in writing, or by such other means as agreed upon by the Trustee, the Stock Fund Fiduciary
and the Company. These directions shall be held in confidence by the Trustee and the Stock Fund Fiduciary and shall not be divulged to the Company, or any officer or employee 

  
 19 








 
thereof, or any other person except to the extent that the aggregate consequences of such directions are reflected in reports regularly communicated to any such person in the ordinary course of
the performance of the Trustee’s services under the Trust Fund agreement. Upon its receipt of the directions, the Trustee shall vote the shares of Company Stock as directed by the Participant unless otherwise directed by the Stock Fund
Fiduciary. Any share held by Trustee as to which it receives no voting instructions shall be voted by Trustee at the direction of the Stock Fund Fiduciary, and if no direction is provided, the Trustee shall not vote such shares. 

The Trustee shall vote that number of shares of Company Stock not credited to Participants’ Accounts in a manner as directed by the Stock Fund Fiduciary
and if no direction is provided, the Trustee shall not vote such shares. 
 6.07 Tender Offers. 

 

	 	(a)	Upon commencement of a tender offer for any Company Stock securities held in the General Dynamics Stock Fund in the Trust Fund, the Company shall timely notify the Trustee and the Stock Fund Fiduciary in advance of the
intended tender date and shall cause a copy of all materials to be sent to the Trustee and the Stock Fund Fiduciary. The Company shall certify to the Trustee and the Stock Fund Fiduciary that the aforementioned materials represent the same
information distributed to shareholders of Company Stock. Based on these materials and after consultation with the Company, the Trustee and the Stock Fund Fiduciary shall prepare (or cause to be prepared) a tender instruction form and shall provide
a copy of all tender materials to be sent to each Participant with an interest in the General Dynamics Stock Fund, together with the foregoing tender instruction form, to be returned to the Trustee or its designee. The tender instruction form shall
show the number of full and fractional shares of Company Stock credited to each Participant’s Account (both vested and unvested). 

  

	 	(b)	 Each Participant, or Beneficiary in the event of the death of the Participant, or a representative properly designated by that Participant or the
Participant’s legal guardian (to the extent consistent with the terms of an Offer), as “named fiduciary” within the meaning of Section 402(a)(2) of ERISA with respect to an interest in the General Dynamics Stock Fund, shall have
the right to direct the Trustee to tender or not to tender some or all of the shares of Company Stock credited to the Participant’s Account (both vested and unvested). Directions from a Participant to the Trustee concerning the tender of
Company Stock shall be communicated in writing, or such other means as is agreed upon by the Trustee and the Company. These directions shall be held in confidence by the Trustee and the Stock Fund Fiduciary (as applicable) and shall not be divulged
to the Company, or any officer or employee thereof, or any other person except to the extent that the aggregate consequences of such directions are reflected in reports regularly communicated to any such persons in the ordinary course of the
performance of the Trustee’s services under the 



  
 20 









	 	
Trust Fund agreement. The Trustee shall tender or not tender shares of Company Stock as directed by the Participant unless otherwise directed by the Stock Fund Fiduciary. The Trustee shall not
tender shares of Company Stock credited to a Participant’s Account for which it has received no directions from the Participant unless otherwise directed by the Stock Fund Fiduciary. 


 

	 	(c)	Except as otherwise required by applicable law, the Trustee shall tender that number of shares of Company Stock not credited to Participants’ Accounts in a manner as directed by the Stock Fund Fiduciary and if no
direction is provided, the Trustee shall not tender such shares. 

  

	 	(d)	A Participant who has directed the Trustee to tender some or all of the shares of Company Stock credited to the Participant’s Account may, at any time prior to the tender offer withdrawal date, direct the Trustee
to withdraw some or all of the tendered shares, and the Trustee shall withdraw the directed number of shares from the tender offer prior to the tender offer withdrawal deadline. A Participant shall not be limited as to the number of directions to
tender or withdraw that the Participant may give to the Trustee. 

  

	 	(e)	A direction by a Participant to the Trustee to tender shares of Company Stock credited to the Participant’s Accounts shall not be considered a written election under the Plan by the Participant to withdraw, or have
distributed, any or all of his withdrawable shares. The Trustee shall credit to each Account of the Participant from which the tendered shares were taken the proceeds received by the Trustee in exchange for the shares of Company Stock tendered from
that Account. Pending receipt of directions (through the Plan Administrator) from the Participant or the Investment Committee or the Stock Fund Fiduciary, as the case may be, as to which of the remaining investment funds the proceeds should be
invested in, the Trustee shall invest the proceeds in the applicable default investment fund as shall be designated by the Investment Committee. 

  

	 	(f)	The tender offer period is that period during which tender offer is outstanding and may be accepted or rejected or during which time an acceptance or rejection may be withdrawn. 


6.08 Additional Restrictions. Restrictions may be imposed on the Accounts of certain Participants with General Dynamics Stock Fund
investments to comply with any securities laws or Company policies. 
 6.09 Special Fiduciary Provisions Concerning Company Stock.
The Trustee shall adopt procedures designed to safeguard the confidentiality of information relating to the purchase, holding, and sale of such securities, and the exercise of voting, tender and similar rights with respect to such securities by
Participants (and Beneficiaries), except to the extent necessary to comply with Federal laws or state laws not preempted by ERISA. The Stock Fund Fiduciary shall monitor the sufficiency of the foregoing procedures to safeguard the confidentiality of
such information and such procedures are being followed. 

  
 21 








 6.10 No Obligation to Acquire Securities. Pursuant to Treasury Regulation §
54.4975-11(a)(7)(i), the Plan is not obligated to acquire securities from a particular security holder at an indefinite time determined upon the happening of an event (such as the death of the holder). 

6.11 General Dynamics Stock Fund. 
  

	 	(a)	The General Dynamics Stock Fund is intended to be a feature of the Plan that shall be invested 100% in Company Stock. The General Dynamics Stock Fund is intended to remain so invested without regard to the
diversification of assets, subject to the discretion of the Stock Fund Fiduciary. 

  

	 	(b)	Stock Fund Fiduciary. Notwithstanding anything in the Plan or the Trust Fund to the contrary, the Stock Fund Fiduciary shall be the exclusive independent fiduciary and investment manager for the General Dynamics
Stock Fund. The Stock Fund Fiduciary shall have the exclusive fiduciary authority and responsibility, in its sole discretion, to determine whether continuing the General Dynamics Stock Fund as an investment option in accordance with the terms of the
Plan is prudent under ERISA (either with respect to continuing to permit new investment in the General Dynamics Stock Fund, continuing to hold Company Stock, or both).In making such a determination, the Company intends that the Stock Fund Fiduciary
consider the risk associated with the General Dynamics Stock Fund not standing alone, but in light of the availability of other investment funds under the Plan and the ability of Plan participants to construct a diversified portfolio of investments
consistent with their individual desired level of risk and return. 

  

	 	(c)	Powers of the Stock Fund Fiduciary. Notwithstanding anything in the Plan to the contrary, the Stock Fund Fiduciary shall at all times have the exclusive fiduciary authority and responsibility to exercise the
following powers: 

  

	 	(1)	in connection with a determination that purchasing Company Stock is no longer prudent under ERISA, to suspend or prohibit the investment of new Contributions in the General Dynamics Stock Fund; 


 

	 	(2)	in connection with a determination that purchasing Company Stock is no longer prudent under ERISA, to suspend or prohibit the transfer of Participant Account balances into the General Dynamics Stock Fund;



  
 22 









	 	(3)	in connection with a determination that purchasing Company Stock is no longer prudent under ERISA, to eliminate the General Dynamics Stock Fund as an investment fund under the Plan and to sell or otherwise dispose of
all of the Company Stock held in the General Dynamics Stock Fund; 

  

	 	(4)	to suspend or prohibit the transfer of Participant Account balances out of the General Dynamics Stock Fund during any period in which the Stock Fund Fiduciary is directing the sale or other disposition of the Company
Stock in the General Dynamics Stock Fund; 

  

	 	(5)	unless otherwise directed by the Investment Committee, to designate an alternative investment fund available under the Plan for the temporary investment of any proceeds from any sale or other disposition of Company
Stock, following the completion of such sale or other disposition, pending Participant directions to the Trustee with respect to the investment of such proceeds; 

  


	 	(6)	to vote the shares of, and respond to tender offers with respect to, Company Stock held by the Plan in the General Dynamics Stock Fund, subject to the terms of the Plan; and 


 

	 	(7)	to instruct the Trustee with respect to the foregoing matters. 

 6.12 Self-Directed
Brokerage Window. The Investment Committee, in its discretion, may allow for the Plan to provide Participants and Beneficiaries with the option to invest money in their Plan Accounts through a self-directed brokerage window investment
arrangement (or other similar arrangement) in accordance with any rules established for such arrangement. The decision to invest through a self-directed brokerage window investment option (or other similar arrangement) is the sole responsibility of
each Participant (or Beneficiary, as the case may be). To the extent a self-directed brokerage window investment arrangement (or other similar arrangement) is available, each Participant (or Beneficiary, as the case may be) shall be the “named
fiduciary” (as described in Section 402(a)(2) of ERISA) with respect to such self-directed brokerage window investment arrangement (or other similar arrangement), which Participants (or Beneficiaries, as the case may be) will not be able
to use to acquire Company Stock. 
 6.13 Managed Account. The Investment Committee in its discretion may engage investment managers
to manage the Accounts of Participants (if so elected by Participants) upon such terms as agreed to by the Investment Committee and such investment managers. 

  
 23 








 ARTICLE VII 

VESTING AND FORFEITURES 

7.01 General. Each Participant and Inactive Participant shall have a continuing interest under this Plan until his or her Account is
distributed or forfeited. An individual Account will be valued in accordance with this Article VII. 
 7.02 Vested Account. A
Participant or Inactive Participant shall have a Vested Account balance in accordance with the following provisions: 
  

	 	(a)	Vested as of the Effective Date. Participants and Inactive Participants who are vested in any portion of their Account balance as of the Effective Date of the Plan shall continue to be vested in those balances.


  

	 	(b)	Immediate Vesting. A Participant shall be 100% vested in his or her 401(k) Contributions, Roth Elective Deferrals, After-Tax Contributions, Rollover Contributions, catch-up contributions as described in
Section 4.08, dividends from investments in the General Dynamics Stock Fund to which the election contemplated in Section 8.14 herein applies, and safe harbor Employer Matching Contributions described in Section 5.01. All earnings
allocated on all of the foregoing shall also be 100% vested. 

  

	 	(c)	Vesting of Certain Employer Contributions. Participants and Inactive Participants shall become fully vested in all other Employer Contributions and earnings thereon credited to their Accounts upon the earliest to
occur of the following: 

  

	 	(1)	Satisfaction by the Participant or Inactive Participant of the Continuous Service requirements set forth in the Supplement applicable to that Participant or Inactive Participant; 


 

	 	(2)	Termination of a Participant’s or Inactive Participant’s employment from the Affiliated Employers by reason of the Participant’s or Inactive Participant’s death, Disability, or layoff (in accordance
with Section 7.02(e)) or discharge without fault (by reason of failing to obtain any required security clearance or as part of a reduction-in-force program as defined by uniform, non-discriminatory guidelines established by the Company); or


  

	 	(3)	Termination of the employment of a Participant or Inactive Participant by reason of retirement as described in the applicable provisions of Section 8.01(a). 


  
 24 









	 	(d)	Continuous Service. Subject to any administrative rules on Continuous Service established from time to time by the Plan Administrator, an individual’s Continuous Service is the sum of the following:


  

	 	(1)	That period of employment with the Affiliated Group commencing on the later of the Effective Date or the individual’s first Hour of Service and ending on the individual’s Termination Date; 


 

	 	(2)	For an individual who shall be in the employment of the Affiliated Group on the Effective Date, that period of Continuous Service prior to the Effective Date accrued under the terms of the Plan as it existed prior to
such date; and 

  

	 	(3)	In the event an Employee who was not fully vested under Section 7.02(c) incurs a Termination Date, and is subsequently reemployed, his or her Continuous Service recognized in his or her previous period of
employment will be recognized in his or her subsequent period of employment after he or she completes one year of Continuous Service following his or her reemployment. 


 

	 	(e)	Termination Date. Subject to Section 3.06, an Employee’s “Termination Date” shall mean that last date on which he or she performed or was deemed to have performed an Hour of Service for the
Affiliated Group as reported by an Affiliated Group Member. For these purposes, any Participant who performs any services beyond the level of merely committing to be available to perform services for any period shall not be treated as having
incurred a Termination Date for Plan purposes during such time. 

  

	 	(f)	One-Year Break-in-Service. A “One-Year Break-in-Service” shall mean any Plan Year within which the Employee fails to complete one Hour of Service. 


7.03 Forfeitures. 
  

	 	(a)	If a Participant or Inactive Participant terminates employment and fails to vest in his or her Employer Contributions described under Section 7.02(c), all non-vested amounts and shares then in the
Participant’s or Inactive Participant’s Account as of his Termination Date shall be forfeited the earlier of: 

  

	 	(1)	The distribution date of the entire vested portion of the Participant’s or Inactive Participant’s Account attributable to Employer Contributions; or 


 

	 	(2)	The last day of the Plan Year in which the Participant or Inactive Participant incurs five consecutive One-Year Breaks-in-Service. 


Furthermore, for purposes of Section 7.03(a)(1) above, in the case of a Participant or Inactive Participant whose vested benefit derived
from Employer Contributions is zero, such individual shall be deemed to have received a complete distribution of this vested portion upon his or her Termination Date. 

  
 25 









	 	(b)	Reinstatement of Forfeitures. An amount forfeited under Section 7.03 shall be reinstated if the Participant or Inactive Participant again becomes an Employee of the Affiliated Group. Notwithstanding the
foregoing, if such an individual received a distribution of any amount upon termination, such distribution must be repaid to the Plan (valued as of the distribution date) for a reinstatement to be made. Such repayment must be made before the later
of (1) five years after the Termination Date, or (2) five years after the date of re-employment. Any reinstated amount (not including repayments) described in this Section shall be subject to the normal vesting provisions of
Section 7.02(c). In addition, if the value of a Participant’s Account was forfeited as a result of a distribution from the Plan prior to termination of employment, such value shall be restored to the Participant’s Account provided
such Participant repays to the Plan, in cash and in a lump sum, the value of the entire withdrawal and any loan amounts that were defaulted as part of a distribution upon a termination (less any amounts withdrawn from a rollover account), prior to
any Termination Date. 

 In the event the individual repays the full amount distributed to him or her, the undistributed
portion of the Participant’s Account will be restored in full, unadjusted by any gains or losses. The source for such reinstatement shall be: 
  

	 	(1)	any Forfeitures occurring during the Plan Year; then 

  

	 	(2)	any income or gain to the Plan (pursuant to Treasury Regulation Section 1.411(a)-7(d)(6)(iii)(C)); and last, 

  

	 	(3)	an Employer Contribution in an amount sufficient to restore Forfeited Accounts provided, however, that if an Employer non-elective contribution is made for such Plan Year, such contribution shall first be applied to
restore any such Accounts and the remainder shall be allocated in accordance with the terms of the Plan. 

  

	 	(c)	Application of Forfeitures. All forfeitures of Employer Contributions and earnings thereon from the Accounts of any Participant or Inactive Participant shall be applied as a credit to reduce subsequent Employer
Contributions or used to pay expenses of the Plan consistent with Section 10.22. All amounts so forfeited and applied shall be determined as of the accounting date coincident with or immediately following the date on which the event resulting
in such forfeiture occurs. However, in the event the Plan is terminated, any amount not so applied by the Trustee shall be credited ratably to the Accounts of Participants and Inactive Participants in proportion to the amounts of their respective
Accounts attributable to Employer Contributions. 


  
 26 









	 	(d)	Pursuant to Treasury Regulation § 54.4975-11(d)(4), if a portion of a Participant’s or Inactive Participant’s Account is forfeited, Company Stock must be forfeited only after other assets.


 7.04 Value Upon Distribution. The amount of a Participant’s or Inactive Participant’s distribution shall
equal the Participant’s Vested Account determined on the Valuation Date coincident with or immediately after the date on which the distribution is requested by the Participant or his or her Beneficiary. 

ARTICLE VIII 

DISTRIBUTIONS UPON RETIREMENT, TERMINATION OR DEATH 

8.01 Right to Payment. For purposes of this Article VIII, the term “Participant” shall refer to both Participants and
Inactive Participants. Upon termination of employment with the Affiliated Employers by reason of (a) through (d) below, the Participant or, in case of death, the Participant’s Beneficiary, shall be eligible to receive a distribution
in the time and manner described in this Article VIII. For purposes of this Article VIII, a termination of employment shall be the Termination Date on which a Participant’s employment with the Affiliated Employers is terminated because of the
first to occur of the following: 
  

	 	(a)	Retirement under a Pension Plan. For any Participant who was not a participant in the General Dynamics Corporation 401(k) Plan 3.0 or the General Dynamics Corporation 401(k) Plan for Represented Employees on or
before December 1, 1999, such Participant will be treated as retired for purposes of this Section if he terminates employment with an Employing Unit after he has attained the age of 55. In such event, the Participant’s Vested Account
balance may be distributed pursuant to any of the methods provided under Sections 8.02 and 8.05 below, or as otherwise provided in an applicable Supplement. 


If an Employee was a participant in the General Dynamics Corporation 401(k) Plan 3.0 or the General Dynamics Corporation 401(k) Plan for
Represented Employees on or before December 1, 1999, and such Employee participates in the Plan, such Participant will be treated as retired for purposes of this Section if he terminates employment with an Employing Unit at the earlier of
age 55 or the date the Participant satisfies the conditions for normal or early retirement under a defined benefit pension plan, maintained by or for an Employing Unit, in which the Participant participates, or if such Participant does not
participate in such a defined benefit pension plan, the date he would otherwise satisfy the conditions for normal or early retirement under the applicable defined benefit pension plan. In such event, the Participant’s Vested Account balance may
be distributed pursuant to any of the methods provided under Sections 8.02 and 8.05 below, or as otherwise provided in an applicable Supplement. 

  
 27 









	 	(b)	Death. The date of the Participant’s death prior to the commencement of distribution of his or her Vested Account from the Plan. In such event, the Participant’s Vested Account balance may be
distributed pursuant to either of the methods provided under Sections 8.02 and 8.05 below, or as otherwise provided in an applicable Supplement. 

  

	 	(c)	Disability. The date the Participant terminates from the employ of the Affiliated Group at any age by reason of a Disability. In such event, the Participant’s Vested Account balance may be distributed
pursuant to any of the methods provided under Sections 8.02 and 8.05 below, or as otherwise provided in an applicable Supplement. 

  

	 	(d)	Other Terminations. The date the Participant terminates employment for any reason, except as otherwise provided for in this Section 8.01, from the Affiliated Group pursuant to Section 7.02(e). In such
event, the Participant’s Vested Account balance may be distributed pursuant to the method provided under Sections 8.02 or 8.05 below. Notwithstanding anything to the contrary, distributions of a Participant’s Vested Account and
earnings thereon shall be permitted on account of severances from employment regardless of when the severance from employment occurred or occurs. 


8.02 Form of Payment. The normal form of benefit under the Plan is a lump sum. Subject to the conditions set forth in this Article
VIII, a Participant, or in the case of his or her death, his or her Beneficiary, may elect to receive his or her Vested Account balance in the forms specified below, as applicable pursuant to Section 8.01, or as otherwise provided in an
applicable Supplement. 
  

	 	(a)	Lump Sum. By payment in a single lump sum, valued as of the Valuation Date coincident with or after the date on which payment is requested. 


 

	 	(b)	Partial Distributions. By payment of partial lump sums (in amounts no less than $500 or 100% of the available Account balance if less than $500), valued as of the Valuation Date coincident with or after the date
on which such payment is requested. The value of and balances in the Vested Account will be reduced by the amount of any partial lump sums in accordance with any rules established by the Plan Administrator. 


 

	 	(c)	Installments. 

 By payment in the form of monthly or annual fixed-amount installments
($500 minimum with amount changes permitted annually). Such a Participant may subsequently elect a lump-sum distribution of his or her Vested Account balance at any time by notifying the Plan Administrator. All installment payments under the Plan
will be suspended upon a Participant’s reemployment with an Employer and subsequent active participation in the Plan. 

  
 28 








 8.03 Distributions Made in Cash or Shares. All lump sum or total distributions requested
by a former Employee or the designated Beneficiary of a deceased Participant shall be made in cash (or if the Participant so elects in full shares of Company Stock to the extent deemed held in his or her Account). In addition, fractional shares of
Company Stock shall be paid in cash and valued as of the date the distribution request is processed, but in any event after the Participant terminates employment with the Affiliated Group Member pursuant to Sections 8.01 (a), (b), (c) and
(d) above, or requests a withdrawal or payment of his or her deferred Account balance pursuant to this Article VIII. Notwithstanding anything to the contrary, all distributions made pursuant to Code Section 411(a)(11) shall be paid in
cash. 
 8.04 Commencement of Payment. Except as provided below in this Section 8.04, payment of a Participant’s Vested
Account balance shall be made or installment payments will commence as soon as practicable after the appropriate date of termination of employment under Section 8.01 above, in accordance with such practices as the Plan Administrator may in its
judgment implement. In accordance with Code Sections 411(a)(11) and 401(a)(31)(B), Department of Labor Regulations Section 2550.404a-2, and any other applicable law, if a Participant’s or Beneficiary’s Vested Account balance at the
time of distribution is less than or equal to $5,000, distributions may be made in a nondiscriminatory manner on behalf of a Participant or Beneficiary before any “required commencement date” (defined below) without his or her consent as
soon as administratively practicable. In the event of a mandatory distribution greater than $1,000 in accordance with the provisions of this Section 8.04, if a Participant does not elect to have such distribution paid directly to an eligible
retirement plan specified by the Participant (if allowed under applicable law) in a direct rollover or to receive the distribution directly in accordance with Sections 8.02 or 8.09, then the Plan Administrator will pay the distribution in a direct
rollover to an individual retirement plan designated by the Plan Administrator in accordance with Internal Revenue Code Section 401(a)(31)(B) and any authority promulgated thereunder. For Participants who attain age 70 1⁄2, distribution of benefits must be made or commence no later than April 1 of the calendar year following the later of the calendar year in which the
Participant attains age 70 1⁄2 or the calendar year in which he retires (his or her “required commencement date”). The required commencement date of
a Participant who is a 5 percent owner (as defined in Section 416 of the Code) shall remain April 1 of the calendar year next following the calendar year in which he attains age 70 1⁄2. All distributions from the Plan shall be made in accordance with Code Section 401(a)(9) and regulations promulgated thereunder, including Treasury Regulations §§ 1.401(a)(9)-2 through
1.401(a)(9)-9. All distributions shall also comply with the Incidental Death Benefit requirement of IRC 401(a)(9)(G). The provisions reflecting Section 401(a)(9) override any distribution options in the Plan inconsistent with
Section 401(a)(9). With respect to Participants whose balances transferred to the Plan from an Other General Dynamics Corporation 401(k) Plan, such distributions will continue under the Plan, but consistent with Section 8.04 of the Other
General Dynamics Corporation 401(k) Plan. 
 8.05 Deferral of Payment. A Participant or Beneficiary who is eligible to receive
payment of his or her Vested Account pursuant to Section 8.01 may elect to defer such payment until his or her required commencement date (as defined in Section 8.04 above). The 

  
 29 








 
deferring Participant or Beneficiary may elect to receive a lump-sum distribution of his or her entire Vested Account at any time after the initial deferral and before his or her required
commencement date by requesting a distribution in the manner prescribed by the Plan Administrator. Notwithstanding the foregoing, the Vested Account balance of a deferring Participant who terminated employment may be distributed pursuant to any of
the methods provided above or in a partial lump-sum payment and partial deferral. Effective for deferral dates prior to January 1, 1998, with respect to balances under the General Dynamics Corporation 401(k) Plan 3.0 or the General Dynamics
Corporation 401(k) Plan for Represented Employees that transferred to the Plan, in the event that the Participant fails to elect a form of benefit, his or her Vested Account shall be distributed in lump sum form. 

8.06 Designation of Beneficiary. Each Participant from time to time may designate a Beneficiary to whom his or her benefits may be paid
in the event of his or her death. “Beneficiary” shall mean (a) the person designated by the Participant either (i) in writing, on a form prescribed by the Plan Administrator and on file with the Plan’s designated
recordkeeper, to receive a distribution upon the death of a Participant or (ii) in such other manner as provided by the Plan Administrator, or (b) the estate of the Participant in the event that no such designation shall have been made or
the person so designated shall have died prior to or coincident with the Participant. Notwithstanding anything to the contrary contained in the Plan, the designated Beneficiary of a legally married Participant shall be the Participant’s spouse.
Any Beneficiary designation to the contrary shall be void unless such spouse of the Participant consents in writing to the Beneficiary designation. Such spouse’s written consent shall be given on such forms as designated by the Plan
Administrator. The consent shall acknowledge the effect of the consent and must be witnessed by a Plan representative or notary public. Only valid Beneficiary designation forms on file with the Plan’s recordkeeper will be honored. Any
Beneficiary designation forms misfiled elsewhere by Participants will be void. Accordingly, if a Participant does not have a valid Beneficiary designation form on file with the Plan’s designated recordkeeper, then the Participant shall be
treated as not having designated a Beneficiary. The designated Beneficiary of a Participant or an alternate payee, as defined in Section 414(p) of the Code, (unless otherwise provided in a Qualified Domestic Relations Order) shall not be
entitled to designate another Beneficiary. Upon the death of the designated Beneficiary of a Participant after the designated Beneficiary has become entitled to receive distribution of the Participant’s Account, payment shall be made to the
designated Beneficiary’s estate pursuant to Section 8.07. Any disclaimer with respect to benefits provided herein and any power of attorney must be made consistent with any applicable law (including ERISA and the Code) and any other rules
established by the Company for the orderly administration of the Plan. A Participant may from time to time authorize a third-party representative to access certain Account information and to take certain actions on the Participant’s
behalf. Such authorization shall be (i) in writing, on a form prescribed by the Plan Administrator or its designee, or (ii) in such other form and manner as accepted by the Plan Administrator. Only valid authorizations on file
with the Plan’s recordkeeper will be honored. 
 8.07 Special Rules for Distribution In Case of Death. If a Participant dies
before receiving his or her entire Vested Account balance, benefits shall be paid to his or her designated Beneficiary. If a deceased Participant failed to designate a Beneficiary before his or her death, or if all of the designated Beneficiaries
die before the Participant, the Participant’s benefits shall be distributed in accordance with the provisions set forth in Section 8.06 above. In 

  
 30 








 
addition, the following rules shall apply with respect to benefits distributed after the Participant’s death: 
  

	 	(a)	In the event that the Participant’s benefits are distributed to his or her estate pursuant to Section 8.06, the maximum period over which installment payments shall be payable shall be 5 years.


  

	 	(b)	In the event that the Participant dies before receiving all or part of a distribution from his or her Vested Account but after he has properly requested such a distribution, the distribution shall be paid in accordance
with his or her election (that is, paid to his or her estate or Beneficiary). 

  

	 	(c)	In the event that the designated Beneficiary dies after commencing receipt of distributions but before the entire Vested Account balance is distributed, the remaining balance shall be distributed to the
Beneficiary’s estate. 

  

	 	(d)	In the event that the Participant dies after terminating employment with the Affiliated Employers and after deferring receipt of his or her Vested Account balance pursuant to Section 8.05, such Vested Account
balance shall be distributed in accordance with Section 8.06. 

  

	 	(e)	If any portion of a Participant’s Vested Account is payable to a designated Beneficiary who is a minor at the time of such distribution, the distribution may be paid to the duly appointed guardian of such
minor’s estate or to the custodian of a Uniform Transfer to Minors Act or Uniform Gifts to Minors Act account for the benefit of such minor Beneficiary. 


8.08 Missing Participants or Beneficiaries. Each Participant and each designated Beneficiary must provide his or her post office
address, and any change in post office address, to the Plan Administrator pursuant to procedures determined by his or her Employer’s Human Resource Department. Any communication, statement or notice addressed to a Participant or Beneficiary at
his or her last post office address filed with the Plan Administrator or the Employer shall be binding on the Participant and his or her Beneficiary for all purposes of the Plan. Subject to applicable law, neither the Employer nor the Plan
Administrator is required to search for or locate a Participant or Beneficiary. If a Participant or Beneficiary is notified by the Plan Administrator that he or she is entitled to a payment, and the Participant or Beneficiary fails to claim his or
her benefits or make his or her whereabouts known to the Plan Administrator within 5 years after a distribution becomes due, the amount thereof shall be used to reduce Employer Contributions. Should the Participant or Payee subsequently make proper
claim for such amount, it shall be paid to the Trust Fund by the Employer and distributed in accordance with the terms of the Plan. 
 8.09
Direct Rollovers. If payment of a Participant’s benefits constitutes an eligible rollover distribution under Section 402(c) of the Code, then the Participant or other eligible distributee may elect to have such distribution paid
directly to an eligible retirement plan described in Section 402(c)(8)(B) or Section 408A of the Code, or as may be required or limited 

  
 31 








 
by applicable law. Such eligible rollover distribution may be paid in cash or Company Stock, as the Participant or such other eligible distributee shall elect. Each election under this
Section 8.09 shall be made at such time and in such manner as the Plan Administrator shall determine, and shall be effective only in accordance with such rules as shall be established from time to time by the Plan Administrator. 

Any before-tax contribution amount that is distributed on account of hardship shall not be an eligible rollover distribution under this Section 8.09 and
the distributee may not elect to have any portion of such a distribution paid directly to an eligible retirement plan as described above. 
 The term
eligible retirement plan described above shall also mean an annuity contract described in Section 403(b) of the Code and an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or
any agency or instrumentality of a state or political subdivision of a state and which agrees to separately account for amounts transferred into such plan from this Plan and the definition of eligible retirement plan shall also apply in the case of
a distribution to a surviving spouse, or to a spouse or former spouse who is the alternate payee under a Qualified Domestic Relations Order, as defined in Section 414(p) of the Code. 

With respect to the term eligible rollover distribution described above, a portion of a distribution shall not fail to be an eligible rollover distribution
merely because the portion consists of after-tax employee contributions which are not includible in gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or
(b) of the Code (including annuities described in Section 403(b) of the Code), or to a qualified plan (including a qualified defined benefit plan) described in Section 401(a) or 403(a) of the Code that agrees to separately account for
amounts so transferred, including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible. Moreover, the entire amount of any hardship withdrawal
shall not be eligible for rollovers. 
 In addition, notwithstanding anything to the contrary in this Section 8.09, and solely for purposes of applying
the direct rollover provisions of the Plan, only distributions that would be eligible for a direct rollover without regard to Section 401(a)(9)(H) of the Code will be treated as eligible rollover distributions. 

8.10 Distribution to Alternate Payees. The Plan Administrator may direct the Trustee to distribute benefits to an alternate payee, as
defined in Section 414(p) of the Code, on the earliest date specified in a Qualified Domestic Relations Order, without regard to whether such distribution is made or commences prior to the Participant’s earliest retirement age (as defined
in Section 414(p)(4)(B) of the Code) or the earliest date that the Participant could commence receiving benefits under the Plan. 

  
 32 








 8.11 Loans to Participants. The Plan Administrator, in accordance with regulations
promulgated by the IRS and pursuant to such rules as it may from time to time establish and maintain in addition to this Plan document, and upon application by a Participant supported by such evidence as the Plan Administrator requests, may direct
the Trustee to make a loan from the Trust Fund to a Participant subject to the following: 
  

	 	(a)	The principal amount of any loan made to a Participant, when added to the outstanding balance of all other loans made to such Participant from all qualified plans maintained by the Employers, shall not exceed the lesser
of: 

  

	 	(1)	$50,000 reduced by the excess (if any) of the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the date on which such loan was made, over the outstanding balance of
loans from the Plan on the date on which such loan was made; or 

  

	 	(2)	one-half of the Participant’s Vested Account balances under the Plan. 

  

	 	(b)	Each loan must be evidenced by a note in a form approved by the Plan Administrator, shall bear interest at a reasonable rate, and shall require substantially level amortization (with payments at least quarterly) over
the term of the loan. 

  

	 	(c)	Each loan shall specify a repayment period that shall not extend beyond five years or twenty years in the case of loans for a primary residence. 


If, on a Participant’s Termination Date, any loan or portion of a loan made to him under the Plan, together with the accrued interest thereon, remains
unpaid, an amount equal to such loan or any part thereof, together with the accrued interest thereon, shall be charged to the Participant’s Accounts after all other adjustments required under the Plan, but before any distribution pursuant to
Article VIII. The foregoing shall not apply to a Participant during a period in which he is laid off, provided he elects to continue loan payments through personal check. Participants with a Disability, Participants who are receiving short-term
disability benefits from their Employing Unit or Participants who are on a Company-approved leave of absence may make manual loan repayments for the duration of such disability or leave. Moreover, at the discretion of the Plan Administrator, the
foregoing loan rules may be modified in accordance with the terms of any applicable corporate sale, outsourcing or other similar agreement affecting Participants who are part of affected Employing Units and such Participants may be permitted to make
manual loan repayments under such terms and conditions as the Plan Administrator determines. If a Participant is terminated and requests a lump sum distribution while a loan remains unpaid, such loan will be immediately foreclosed and treated as a
taxable event. 
 In determining the adjusted net worth of the Trust Fund as of each accounting date, the Trustee shall disregard loans made to Participants
under this Section 8.11 and any interest and principal payments on such loans received by the Trustee since the last preceding accounting date. For purposes of adjusting Participants’ Accounts under Article VIII, the Company shall
exclude from the credit balance in a Participant’s Accounts the unpaid amount of any loan made to him (disregarding any principal payments made since the last preceding accounting date). Interest paid by a Participant on a loan made to him
under this Section 8.11 shall be credited to the Accounts of the Participant after all other adjustments required under the Plan as of that date have been completed. A deferring Participant who leaves the employ of the Affiliated Employers and
any Participant on an unpaid leave of absence shall not be eligible for a loan from his or her Vested Account. 

  
 33 








 Participants, whether Active Participants or Inactive Participants, may take either two general purpose loans or
one general purpose loan and one principal residence loan, provided that such Participants are on the active payroll of an Employing Unit. The total number and type of loans available hereunder shall be reduced by the corresponding number and type
of loans outstanding under any other plan maintained by the Company such that only two loans (in the combinations described in the preceding sentence) per Participant will be permitted under all plans similar to this Plan. Any loans transferred to
the Plan from an Other General Dynamics Corporation 401(k) Plan shall count toward the limits on loans specified herein. In addition, for any loans so transferred to the Plan from an Other General Dynamics Corporation 401(k) Plan, the name of the
Plan shall be deemed substituted for the name of the Other General Dynamics Corporation 401(k) Plan on any applicable loan notes and all other loan note terms shall remain the same. Notwithstanding any of the foregoing, the Plan Administrator may
allow additional loans with respect to any Business Unit or group of Participants employed at a business that is acquired by the Company and specifically permitted participation herein; provided that the Plan Administrator determines that such
additional loans are administratively feasible and such action is taken solely to accommodate prior loans under any plans affected by such business acquisition. 

8.12 Hardship Withdrawal of Compensation Deferral Contributions. Subject to the following provisions of this Section 8.12, a
Participant may elect to withdraw in the following order, all or any portion of his or her After-Tax Contributions, if any, as well as Rollover Contributions, vested Employer Matching Contributions (other than “safe harbor” Employer
Matching Contributions and any earnings thereon), vested Employer Discretionary Contributions, 401(k) Contributions and Roth Elective Deferrals (including earnings on such contributions prior to 1989), provided that the withdrawal is necessary in
light of immediate and heavy financial needs of the Participant. Such a withdrawal shall be in an amount that is no less than $500, and in no event shall such a withdrawal exceed the amount required to meet this immediate financial need, after
seeking amounts reasonably available from other resources of the Participant (including, pursuant to rules established by the Plan Administrator, electing to receive dividends in cash as described in Section 8.14, all other distributions and
nontaxable loans currently available under the Plan). Each such election shall be filed with the Plan Administrator or its agent at such time and in such manner as the Plan Administrator shall determine, and shall be effective in accordance with
such rules as the Plan Administrator shall establish and publish from time to time. Consistent with Treasury Regulation Section 1.401(k)-1(d), immediate and heavy financial needs are limited to amounts necessary for: 

 

	 	(a)	Unreimbursed medical expenses described in Code Section 213(d) that are previously incurred by the Participant, his or her spouse or his or her dependents (as defined by the IRS in the Code, including, but not
limited to, Section 152 thereof) or necessary for these persons to obtain medical care described in Code Section 213(d); 

  

	 	(b)	Purchase (excluding mortgage payments) of a principal residence for the Participant; 


  
 34 









	 	(c)	Payment of tuition and related educational fees (including room and board) for the next 12 months of post-secondary education for the Participant, his or her spouse or his or her dependents (as defined by the IRS in the
Code, including, but not limited to, Section 152 thereof); 

  

	 	(d)	Preventing foreclosure on or eviction from the Participant’s principal residence; 

  

	 	(e)	Funeral expenses of a family member; 

  

	 	(f)	an IRS tax levy; 

  

	 	(g)	Certain legal fees and costs; 

  

	 	(h)	Covering expenses for the repair of damage to the Participant’s principal residence that would qualify for the casualty deduction under Section 165 of the Code (determined without regard to whether the loss
exceeds 10% of adjusted gross income); or 

  

	 	(i)	Such other events or expenses that constitute an immediate and heavy financial need under Treasury Regulation Section 1.401(k)-1(d) and based on all relevant facts and circumstances. 


8.13 In-Service Withdrawals. A Participant who is employed by the Affiliated Group may elect to withdraw a specified portion of his or
her Vested Account balance as described below (in amounts of not less than $25; and in an age 59 1⁄2 withdrawal, in amounts of not less than $500 or 100
percent of the available amount, whichever is less), subject to the restrictions contained in this Section 8.13 and such other rules and restrictions as the Plan Administrator may from time to time impose. Each election by a Participant under
this Section 8.13 must be filed with the Plan Administrator or its agent at such time and in such manner as the Plan Administrator shall determine, and shall be effective in accordance with such rules as the Plan Administrator shall establish.
The Vested Account portion from which an in-service withdrawal may be made consists of all vested amounts credited to a Participant’s Account (including rollover balances credited pursuant to Section 4.06) and vested transfers from other
plans, except for: 
  

	 	(a)	401(k) Contributions, Roth Elective Deferrals, and all safe harbor Employer Matching Contributions, and earnings thereon (before the Participant’s attainment of age
59 1⁄2); 

  

	 	(b)	vested non-safe harbor Employer Matching Contributions or Employer Discretionary Contributions, and earnings thereon credited to a Participant’s Account, provided that such contributions (and related earnings)
shall be available for in-service withdrawal if (i) such contributions (and related earnings) have remained in the Plan (or any Other General Dynamics Corporation 401(k) Plan) for the 24 months preceding the date the withdrawal is requested and
made or (ii) the Participant has participated in the Plan (or any Other General Dynamics Corporation 401(k) Plan) for at least five years (in the aggregate among such plans) on the date the withdrawal is requested and made; 


  
 35 









	 	(c)	vested non-safe harbor Employer Matching Contributions and the After-Tax Contributions to which they relate, provided that such contributions shall be available for in-service withdrawal if (i) such contributions
have remained in the Plan (or any Other General Dynamics Corporation 401(k) Plan) for the 24 months preceding the date the withdrawal is requested and made or (ii) the Participant has participated in the Plan (or any Other General Dynamics
Corporation 401(k) Plan) for at least five years (in the aggregate among such plans) on the date the withdrawal is requested and made. 

 All
amounts and/or shares withdrawn shall be drawn from a Participant’s Account in accordance with rules established by the Plan Administrator from time to time. Notwithstanding the foregoing, there shall be no restriction on the number of
withdrawals with respect to any Vested Account balances under this Section. 
 8.14 ESOP Dividend Distribution Election. In
accordance with such rules as the Plan Administrator establishes and consistent with Code Section 404(k), all Participants may elect at any time either to reinvest any regularly scheduled quarterly (or annual) cash dividends attributable to
their investment in the ESOP portion of the General Dynamics Stock Fund or to receive the value of such dividends in cash. If no such election is made, such dividends will be reinvested in the General Dynamics Stock Fund. Such election on file with
the Plan Administrator at the end of the day on the business day that is ten business days prior to the dividend payment date shall be treated as irrevocable. The treatment elected under such irrevocable election shall be processed as soon as
administratively practicable. The foregoing only applies to regularly scheduled quarterly (or annual) cash dividends actually paid to the Plan. Any other dividends, including special dividends, or dividends paid in the form of shares of the Company
or other property, are not eligible for the foregoing dividend distribution election and will be reinvested in the General Dynamics Stock Fund or as otherwise provided under the Plan. 

ARTICLE IX 
 PLAN
ACCOUNTING 
 9.01 Separate Accounts. The Plan Administrator shall maintain the following Accounts, which shall include
amounts transferred to the Plan, in the name of each Participant or Inactive Participant: 
  

	 	(a)	a “Before-Tax Account,” which shall reflect his or her 401(k) Contributions, if any, under the Plan, and the income, losses, appreciation and depreciation attributable thereto; 


 

	 	(b)	an “After-Tax Account” which shall reflect his or her voluntary After-Tax Contributions, if any, under the Plan, and the income, losses, appreciation and depreciation attributable thereto; 


  
 36 









	 	(c)	a “Company Match Account,” which shall reflect his or her share of Employer Contributions (except as provided in (d) below) under the Plan, and the income, losses, appreciation and depreciation
attributable thereto; 

  

	 	(d)	a “Non-Contributory Retirement Contribution Account,” which shall reflect amounts attributable to Employer Discretionary Contributions described in Section 5.02(c) and to any other contributions specified
only in a Supplement; and 

  

	 	(e)	a “Rollover Account,” which shall reflect Rollover Contributions rolled over to the Plan from another qualified plan, if any, and the income, losses, appreciation and depreciation attributable thereto.


 The Plan Administrator will also maintain such other Accounts in the names of Participants or otherwise as it considers advisable
(including a “Roth Elective Deferral Account” and “Roth Rollover Account” as described in Section 4.10). Unless the context indicates otherwise, references to a Participant’s “Account” or “Accounts”
means all accounts maintained in his or her name under the Plan. 
 9.02 Daily Accounting Dates. Participants’ Accounts shall be
adjusted as of the end of each business day. A “business day” shall mean any day on which the New York Stock Exchange is open for business. Accordingly, an “accounting date” means each business day as defined herein as of which
Participants’ Accounts are adjusted under the Plan. 
 9.03 Adjustment of Participants’ Accounts. Participants’
Accounts shall be maintained on the basis of dollar values or units that may be converted to dollar values. Pursuant to the accounting procedures of the Plan Administrator, Participants’ Accounts will be adjusted on each accounting date to
reflect the adjusted net worth (as described below) of the investment funds in which such Accounts have an interest and to reflect any contributions and distributions since the previous accounting date (including adjustments for Plan expenses that
are paid out of Plan assets). The “adjusted net worth” of an investment fund as of any accounting date means the then-net worth of that investment fund as determined by the Trustee in accordance with the provisions of the Trust Agreement.
Accounts held under an annuity contract shall be adjusted in accordance with the annuity contract. 
 9.04 Allocation of Employer
Contributions. As of each regular accounting date on which a Participant’s 401(k) Contribution, Roth Elective Deferral or After-Tax Contribution is credited to his or her Accounts, Employer Contributions shall be allocated and credited to
the Accounts of the same Participants in accordance with Sections 5.01, 5.02 and 6.02. Subject to Section 8.14 as applicable, regular quarterly or annual dividends declared by the Company and received on Company Stock held by the Trustee
shall be used to purchase shares or units of Company Stock, and the Participant’s or Inactive Participant’s Accounts shall be credited with a proportionate number of such shares or units determined on the basis of the number of shares or
units in each Participant’s or Inactive Participant’s Account. 
 9.05 Crediting of Participant Contributions. Subject to
Article IV, each Participant’s 401(k) Contributions, Roth Elective Deferrals or After-Tax Contributions shall be 

  
 37 








 
credited to his or her Before-Tax Account, Roth Elective Deferral Account, and After-Tax Account, as applicable, as soon as practicable, but in any event no later than the 15th business day of
the next following month, subject to permissible extensions. 
 9.06 Charging Distributions. All payments or distributions made to a
Participant or his or her Beneficiary will be charged to the appropriate Accounts of such Participant. 
 9.07 Account Notices. In
accordance with applicable law, the Plan Administrator will provide to each Participant such notices as may be required to increase awareness of automatic enrollment, safe harbor, diversification and other rights affecting Accounts and participation
herein. 
 9.08 Statement of Account. As soon as practicable after the end of each calendar quarter, or at such other times as
required by applicable law or at such other times as the Plan Administrator may decide, each Participant will be furnished with a statement reflecting the condition of his or her Accounts in the Trust Fund as of that date. No Participant, except one
authorized by the Plan Administrator, shall have the right to inspect the records reflecting the Accounts of any other Participant. 
 9.09
Contribution Limitations. For each Plan Year, the annual addition (as defined below) to a Participant’s Accounts under the Plan shall not exceed the lesser of $53,000 (for Plan Years commencing on or after January 1, 2016, or as
adjusted for increases in the cost-of-living under Section 415(d) of the Code) or 100 percent of the Participant’s Section 415 compensation (as defined below) during that Plan Year. The term “annual addition” for any Plan
Year means the sum of the Employer Contributions, Contributions made by Participants and forfeitures credited to a Participant’s Accounts for that year. Any Contributions made by Participants which cannot be allocated to a Participant because
of the foregoing limitations (and any gains attributable thereto) shall be returned to him. Any Employer Contributions which cannot be allocated to a Participant because of the foregoing limitations shall be applied to reduce Employer Contributions
in succeeding Plan Years, in order of time. For all applicable purposes under the Plan (including determining amounts eligible for Deferral Pay), a Participant’s “Section 415 compensation” means his or her total cash compensation for
services rendered to the Employers as an Employee, determined in accordance with Treasury Regulation Section 1.415-2(d)(11)(i) and in accordance with the timing requirements of the final regulations promulgated under Section 415 of the
Code, but including pre-tax deferrals or payments made pursuant to Sections 125, 132(f) and 402(e)(3) of the Code and excluding any contribution for medical benefits after separation from service (within the meaning of Code Sections 401(h) or
419A(f)(2)) which is otherwise treated as an annual addition. Contributions made on behalf of a Participant in any qualified defined contribution plan of the Company will not exceed the limitation (as may be adjusted from time to time) under
Section 415 of the Code. 

  
 38 








 9.10 Allocation of Earnings to Distributions of Excess Contributions. The earnings
allocable to distributions of Participants’ 401(k) Contributions exceeding the limits of Sections 4.05 (Code Section 402(g) limit) and Participants’ After-Tax Contributions and Employer Matching Contributions exceeding the limits
of Section 9.11 (ACP limit) shall be determined as follows in the event any such testing is required under the Plan for any Plan Year: 
  

	 	(a)	for Section 4.05, earnings shall be determined by multiplying the income or loss attributable to the Participant’s 401(k) Contributions for the Plan Year by a fraction, the numerator of which is the excess
contributions to be distributed to the Participant for the Plan Year and the denominator of which is the sum of: (i) the Participant’s Before-Tax Account balance on the first day of the Plan Year, and (ii) the Participant’s
401(k) Contributions for such Plan Year. 

  

	 	(b)	for Section 9.11, earnings shall be determined by multiplying the income or loss attributable to the Participant’s After-Tax and Employer Matching Contributions for the Plan Year by a fraction, the numerator
of which is the excess aggregate contributions to be distributed to the Participant for the Plan Year and the denominator of which is the sum of: (i) the total of the Participant’s After-Tax Account balance and Company Match Account
balance on the first day of the Plan Year, and (ii) the total of the Participant’s After-Tax Contributions and Employer Matching Contributions for such Plan Year. 


Excess contributions and excess aggregate contributions shall not be adjusted for income or loss for the gap period. 

9.11 Limitation on Allocation of Contributions. In the event the testing contemplated by this Section 9.11 is required for any
Plan Year, this Section 9.11 shall apply. 
 Notwithstanding the foregoing provisions of this Article IX, in no event shall the actual contribution
percentage (“ACP,” as defined below) of the Highly Compensated Employees (as defined in Section 2.19) who are Plan Participants for any Plan Year exceed the greater of: 

 

	 	(a)	the contribution percentage of all other Participants for the current Plan Year multiplied by 1.25; or 

  

	 	(b)	the contribution percentage of all other Participants for the current Plan Year multiplied by 2.0; provided that the contribution percentage of the Highly Compensated Employees does not exceed that of all other
Participants for the current Plan Year by more than 2 percentage points. 

 The ACP of a group of Participants for a Plan Year means the
average of the actual contribution ratios (determined separately for each Participant in such group) of such group of Participants, where the actual contribution ratio for a Participant means the ratio of: (i) the sum of Employer Matching
Contributions (and, at the election of the Company, any qualified nonelective contributions (“QNECs”) or qualified matching contributions (“QMACs”) made to the Plan on behalf of the Participant) and Participant After-Tax
Contributions allocated to such Participant for such Plan Year; to (ii) the Participant’s compensation, determined in accordance with Section 414(s) of the Code, for such Plan Year. Pursuant to Treasury Regulation
Section 1.401(m)-2(a)(6)(v), QNECs cannot be taken into account for an applicable year for a non-Highly Compensated Employee to the extent such contributions exceed the product of that non-Highly
Compensated Employee’s compensation and the greater of 5% and 2 times the plan’s 

  
 39 








 
representative contribution rate. Pursuant to Treasury Regulation Section 1.401(m)-2(a)(5)(ii), QMACs cannot be taken into account for a non-Highly Compensated Employee to the extent the
QMAC exceeds the greatest of (1) 5% of compensation, (2) the employee’s elective deferrals for a year, and (3) the product of 2 times the plan’s representative matching rate and the employee’s elective deferrals for a
year. For purposes of this Section 9.11, a Participant means any Employee who is eligible to receive Employer Matching Contributions or to make Participant After-Tax Contributions under the Plan. 

Matching Contributions (that otherwise meet the ACP safe harbor provisions of Code Section 401(m)(11)) may be included in the ACP test, at the discretion
of the Plan Administrator. 
 The Employer Matching Contributions allocated to and Participant After-Tax Contributions made by the Highly Compensated
Employees will be reduced to the extent necessary to meet the requirements of this Section 9.11. For Purposes of this Section 9.11, such Employer Matching Contributions and Participant After-Tax Contributions are collectively referred to
as “Aggregate Contributions.” The reductions will occur in the following manner (and in accordance with guidance set out by the IRS, including Notice 97-2): 
  

	 	(c)	The actual contribution ratio of the Highly Compensated Employee with the highest actual contribution ratio is reduced such that the actual contribution ratio is equal the actual contribution ratio of the Highly
Compensated Employee with the next highest actual contribution ratio, provided, if applicable, that the reduction of the actual contribution ratio will be no more than is necessary to satisfy the ACP test indicated above. 


 

	 	(d)	The process of step (c) is repeated until the ACP test indicated above is satisfied. The total amount of excess Aggregate Contributions is equal to the sum of these hypothetical reductions multiplied, in each case,
by the Highly Compensated Employee’s compensation (as determined above). 

  

	 	(e)	The Aggregate Contributions of the Highly Compensated Employee with the highest dollar amount of Aggregate Contributions are reduced by the amount required to cause that Highly Compensated Employee’s Aggregate
Contributions to equal the dollar amount of the Aggregate Contributions of the Highly Compensated Employee with the next highest dollar amount of Aggregate Contributions. This amount is then distributed as provided below to the applicable Highly
Compensated Employee. However, if a lesser reduction, when added to the total dollar amount already distributed under this step, would equal the total excess Aggregate Contributions determined under step (d), the lesser reduction amount is
distributed. 

  

	 	(f)	If the total amount distributed in accordance with step (e) is less than the total excess Aggregate Contributions determined under step (d), step (e) is then repeated. 


If, because of the foregoing limitations, a portion of the Employer Matching Contributions allocated to, or the After-Tax Contributions (and any applicable
Employer Matching 

  
 40 








 
Contributions thereon) made by a Highly Compensated Employee may not be credited to his or her Account for a Plan Year, such portions of the After-Tax Contributions and vested Employer Matching
Contributions (and the earnings thereon) shall be distributed to such Employee within 2 1⁄2 months after the end of that Plan Year, but in no event later than
the last day of the next following Plan Year. Any such portions of the aforementioned Employer Matching Contributions that are not vested shall be forfeited. 

For purposes of the above ACP test, the actual contribution ratio of a Highly Compensated Employee will be determined by treating all plans subject to Code
Section 401(m) under which the Highly Compensated Employee is eligible (other than those that may not be permissively aggregated) as a single plan. 

The provisions herein relating to the ACP test shall be administered in accordance with Code Section 401(m) and the applicable regulations and guidance
thereunder. 
 9.12 Qualified Separate Lines of Business. In the event that Plan testing described in Sections 4.06 and 9.11
herein is required and occurs on the basis of individual “qualified separate lines of business” (as defined in the Code), Participants who transfer from one separate line of business to another separate line of business will be assigned to
the “qualified separate line of business” in which they are employed on the last day of the applicable testing year for purposes of the testing described in Sections 4.06 and 9.11 herein. Furthermore, such Participants’
applicable total annual pay and total annual contributions will be included in the qualified separate line of business in which they are employed on the last day of the applicable testing year. 

ARTICLE X 
 GENERAL
PROVISIONS 
 10.01 Fiduciary Responsibilities. The Plan Administrator is a named fiduciary and the administrator of the
Plan. The Investment Committee shall be the Plan’s named fiduciary with respect to the selection of investment funds and all other matters pertaining to the investment and management of Plan assets. All conforming changes related to naming the
Investment Committee as the named fiduciary for investment purposes shall be deemed to have been made to this document to effect the purposes and intent of such change. 

The Plan Administrator and the Investment Committee may allocate fiduciary responsibilities among the fiduciaries named in the Plan or may designate other
persons or entities other than named fiduciaries to carry out fiduciary responsibilities. 
 Any of the fiduciaries of the Plan may, by agreement among
themselves, allocate specific responsibilities among themselves or delegate to other persons all or such portion of their fiduciary duties hereunder, as they, in their sole discretion, shall decide, other than those granted to the Trustee under the
Trust Agreement. The Company may purchase insurance to cover the potential liability of all persons who serve in a fiduciary capacity (as defined in ERISA or the Plan) with regard to the Plan. 

  
 41 








 10.02 Fiduciary Liability. The Plan Administrator and members of the Investment Committee
shall use the degree of care, skill, prudence and diligence in carrying out their duties that a prudent man, acting in a like capacity and familiar with such matters, would use in his conduct of a similar situation. 

Except as provided in ERISA, in administering the Plan neither a person designated to act on behalf of the Plan Administrator, nor any member of the
Investment Committee, nor any Employer, nor any director, officer or employee thereof, shall be liable for any acts of omission or commission, except for his or its own individual, willful and intentional malfeasance or misfeasance and each
Employer, the officers, directors and employees of an Employer or the Company, and any member of the Investment Committee shall be entitled to rely conclusively on all tables, valuations, certificates, opinions and reports which shall be furnished
by any actuary, accountant, Trustee, insurance company, counsel or other expert who shall be employed or engaged by the Company, an Employer or the Investment Committee. 

10.03 Administration of the Plan. The Company shall administer the Plan in accordance with its terms and shall have all the powers
necessary to carry out the provisions of the Plan. The Company has the discretionary authority to construe and interpret the provisions of the Plan and make factual determinations thereunder, including the power to determine the rights or
eligibility of Employees or Participants and any other persons, and the amounts of their benefits under the Plan, and to remedy ambiguities, inconsistencies or omissions or to adjust Account balances or benefit payments in the event of overpayments
or underpayments; and such determinations shall be binding on all parties. The Company from time to time may adopt such rules and regulations as may be necessary or desirable for the proper and efficient administration of the Plan and as are
consistent with the terms of the Plan. The Company also, from time to time, may appoint such individuals to act as the Company’s representatives as the Company considers necessary or desirable for the efficient administration of the Plan. The
Company shall have no fiduciary responsibility relating to the selection of investment funds and all other matters pertaining to the investment and management of Plan assets. 

10.04 Investment Committee. The Investment Committee will be comprised of the Senior Vice President and Chief Financial Officer of the
Company, the Vice President – Treasurer of the Company, and the Senior Vice President – Human Resources and Administration (or such other comparable officers of the Company should the titles of the Company’s officers change) (each a
“Committee Member”). Each Committee Member may appoint a designee to serve in the Committee Member’s stead. The Investment Committee shall operate in accordance with its charter adopted by it and as may be amended by it from time
to time, which charter shall be incorporated into the Plan by this reference. 
 10.05 Delegation. The Plan Administrator and the
Investment Committee have the authority to delegate any of their powers or duties to any other person. Any such person may further delegate its powers or duties to another person. Unless otherwise expressly provided, any delegation or subsequent
delegation shall include the same full, final and discretionary authority that the delegating party has and any decisions, actions or interpretations made by any delegate shall have the same ultimate binding effect as if made by the delegating
entity. 

  
 42 








 10.06 Employment of Agents. The Plan Administrator and the Investment Committee may employ
such legal, medical, insurance, accounting, actuarial or other experts as it deems necessary or desirable in its sole discretion, in carrying out the provisions of the Plan. 

10.07 Action by Employers. Any action required or permitted to be taken by an Employing Unit under the Plan shall be by resolution of
its board of directors or any duly authorized officer and any delegates thereof. 
 10.08 Information Required by Company. Each
person entitled to benefits under the Plan shall furnish the Company, as Plan Administrator, with such documents, evidence, data or information as the Company considers necessary or desirable for the purpose of administering the Plan. The records of
the Company as to an Employee’s or Participant’s period of employment, service, Termination Date and reason therefor, leave of absence, reemployment and compensation/Deferral Pay will be conclusive on all persons unless determined to the
Company’s satisfaction to be incorrect. 
 10.09 Review of Benefit Determinations. The Company shall establish a benefits claim
procedure. If a claim for benefits is denied, the Company shall provide notice in writing to the Participant or Beneficiary, if appropriate, within 90 days after the claim is filed (plus an additional 90 days if special circumstances necessitate an
extension). Such notice shall explain the reasons for the denial, the Plan provisions on which the denial is based and any additional material or information needed to perfect the claim; and shall also set forth the procedure for requesting a review
of the claim. Within 75 days of receiving this notice of denial, the Participant may submit a written request for review on appeal to the Plan Administrator. The Participant or Beneficiary, if appropriate, also shall be afforded the opportunity to
review pertinent documents on which the denial is based and to submit comments and address issues in writing. Within 60 days of receiving such a request for review (or within 120 days, if special circumstances necessitate an extension), the Company
shall issue written notice of its decision on the appeal, which notice shall set forth the specific reasons for the decision, including references to the pertinent Plan provisions on which the decision is based. Any claims relating to Disability
will be processed in accordance with the procedures described in the Plan’s summary plan description. No individual shall be permitted to file any lawsuit, either in law or equity, until after such individual has exhausted and complied with the
claim and appeal provisions herein. 
 10.10 Company’s Decision Final. Subject to applicable law, any interpretation of the
provisions of the Plan and any decisions on any matter made by the Company in good faith shall be binding on all persons. A misstatement or other mistake of fact shall be corrected when it becomes known and the Company shall make such adjustment on
account thereof as it considers equitable and practicable. The Company or its delegate shall have full discretion to determine eligibility for benefits or to interpret the Plan, resolve any disputes arising from Plan language, construe any ambiguous
or uncertain terms therein and make all other determinations necessary or advisable for the discharge of its duties under the Plan including but not limited to making findings of facts. As such, benefits will only be paid if the Company determines
that a person is entitled to them. Any such determination, interpretation, resolution or construction made by the Company in good faith shall be final and binding on all persons. 

  
 43 








 10.11 Action by Company. Any action required or permitted to be taken by the Company under
the Plan shall be by action of its Board of Directors or its delegate or by any duly authorized officer or employee. 
 10.12 Waiver of
Notice. Subject to applicable law, any notice required under the Plan may be waived by the person entitled to such notice. 
 10.13
Gender and Number. Where the context admits, words in the masculine gender shall include the feminine and neuter genders, the singular shall include the plural, and the plural shall include the singular. 

10.14 Controlling Law. Except to the extent superseded by laws of the United States, the laws of the state of New York shall be
controlling in all matters relating to the Plan. 
 10.15 Employment Rights. The Plan does not constitute a contract of employment,
and participation in the Plan will not give any Employee the right to be retained in the employ of an Employer, nor any right or claim to any benefit under the Plan, unless such right or claim has specifically accrued under the terms of the Plan.

 10.16 Litigation by Participants. If a legal action begun against the Trustee, the Company or an Employer by or on behalf of any
person results adversely to that person, or if a legal action arises because of conflicting claims to a Participant’s or other person’s benefits, the cost to the Trustee, the Company or the Employer of defending the action will be charged
to the extent permitted by law to the sums, if any, which were involved in the action or were payable to the person concerned. 
 10.17
Interests Not Transferable. The interests of persons entitled to benefits under the Plan are not subject to their debts or other obligations and, except as may be required by the tax withholding provisions of the Code or any state’s
income tax act or pursuant to a Qualified Domestic Relations Order as defined in Section 414(p) of the Code, may not be voluntarily or involuntarily sold, transferred, alienated, assigned or encumbered. 

10.18 Absence of Guaranty. The Company does not in any way guarantee the Trust Fund from loss or depreciation. The liability of the
Trustee, the Company or the Employers to make any payment under the Plan will be limited to the assets held by the Trustee that are available for that purpose. 

10.19 Evidence. Evidence required of anyone under the Plan may be by certificate, affidavit, document or other information which the
person acting on it considers pertinent and reliable, and signed, made or presented by the proper party or parties. 
 10.20
Indemnification. Each officer, director and employee of the Company who has been designated to carry out any fiduciary or administrative responsibility shall be indemnified by the Company against all expenses (including costs and
attorneys’ fees) actually and necessarily incurred or paid by that person in connection with the defense of any action, suit or proceeding in any way relating to or arising from the Plan to which that person may be made a party by reason of his
or her being or having been so designated or by reason of any action or omission or alleged action or omission by that person in such capacity, and against any amount 

  
 44 








 
or amounts which may be paid by that person (other than to the Company) in reasonable settlement of such action, suit or proceeding, where it is in the interest of the Company that such
settlement be made. In cases where such action, suit or proceeding shall proceed to final adjudication such indemnification shall not extend to matters as to which it shall be adjudged that such officer, director or employee is liable for negligence
or misconduct in the performance of his or her duties as such. The right of indemnification herein provided shall not be exclusive of other rights to which any such officer, director or employee may now or hereafter be entitled, shall continue as to
a person who has ceased to be so designated, and shall inure to the benefit of the heirs, executors and administrators of such officer, director or employee. 

10.21 Unclaimed Distributions. If, within a reasonable period of time after any distribution becomes due to a Participant or Inactive
Participant, the same shall not have been claimed, provided due and proper care shall have been exercised by the Trustee and the Employer in attempting to make such distribution, the amount thereof shall be used to reduce Employer Contributions or
used to pay expenses of the Plan consistent with Section 10.22. Should a Participant or Inactive Participant, or Alternate Payee subsequently make proper claim for such amount, it will be paid to the Trust Fund by the Employer and distributed
in accordance with the terms of the Plan. 
 10.22 Plan Expenses. 

 

	 	(a)	All reasonable and proper expenses incurred in the administration of the Plan shall be paid from the Trust Fund, unless paid by the Company or the Employing Unit(s); provided, however, the Company or the Employing
Unit(s) may pay any of such expenses or reimburse the Trust Fund for any payment, or the Trust Fund may reimburse the Company or the Employing Unit(s) for any payment the Company or the Employing Unit(s) has paid. The payment by the Company or the
Employing Unit(s) of any particular expense for a Plan Year shall not be deemed an election to pay that or any other expense in that or any subsequent Plan Year. 

  


	 	(b)	To the extent that expenses are paid from the Trust Fund, the Plan Administrator shall determine how such expenses are to be allocated. Without limitation, expenses may be charged directly against individual
Participant Accounts, against the assets of investment funds or as otherwise determined by the Plan Administrator. The Plan Administrator is authorized to establish administrative fees which may be charged against a Participant’s Account.


  

	 	(c)	Without limitation, (i) expenses may be paid from a clearing or other account, and may be accrued for, based on estimated expenses, against the Plan investment funds or Participant Accounts during any period
determined by the Plan Administrator, and paid as and when determined by the Plan Administrator, and (ii) amounts accrued during a Plan Year may be used to pay expenses incurred in a prior, current or future Plan Year, and true-ups may be
directed by the Plan Administrator from time to time if, to the extent it deems them necessary or desirable. 


  
 45 








 10.23 Disaster Relief. Notwithstanding any provision of the Plan to the contrary, the Plan
shall be administered in accordance with the Katrina Emergency Tax Relief Act of 2005 and any related authority promulgated by any United States administrative agency. 

10.24 Statute of Limitations. After exhausting the Plan’s administrative claim and appeal provisions, and except for claims
relating to Disability, an individual wishing to bring a lawsuit in either state or federal court challenging a claim denial must commence the lawsuit no later than six months after the individual receives a final denial letter indicating the
individual has exhausted his or her administrative appeals and has the right to file a lawsuit. In addition to this six-month deadline that applies to filing a lawsuit after the claims and appeals procedures are exhausted, a general time
limitation shall apply to all lawsuits involving all types of Plan issues except for Disability-related claims. An individual must commence any such lawsuit involving Plan claims no later than two years after the individual first receives
information that constitutes a clear repudiation of the rights the individual is seeking to assert (i.e., the underlying event or issue that should have triggered the individual’s awareness that his or her rights under the Plan may
have been violated). Although any period of time when an individual’s claim is in the claims procedure described above (i.e., the time between when an individual files a claim for benefits with the Plan Administrator and the time the
individual receives a final determination letter from the Plan Administrator) does not count against the two-year period, once the claims procedure process is completed, the two-year period will continue running from the point at which it was
tolled. 
 Legal actions may be brought on a denied Disability claim no later than one year after a final decision is rendered on a claim. 

In order to raise an issue in any legal action related to the claim, an individual must have clearly raised such issue during the claims and appeals procedure
described above. 
 10.25 Mitigation. In order to mitigate any damages or other negative effects, individuals must always carefully
review their account statements, confirmations, payroll records (e.g., for deductions and contributions made to the Plan) and any other records relating to the Plan, and report any discrepancies or other concerns within 30 days of the date of the
applicable record through the procedures discussed in the summary plan description. An individual must file a claim under the Plan’s claim procedures if his or her concerns cannot be resolved within this time. Neither the Company, the Plan, the
Plan Administrator, nor any of their agents or employees will be responsible for damages or other negative effects caused by an individual’s failure to follow these requirements and procedures. 

ARTICLE XI 

AMENDMENT AND TERMINATION 

11.01 Amendment. While the Company expects and intends to continue the Plan, the Company reserves the right to amend the Plan (in
accordance with the procedures set forth in Section 10.11) from time to time, except as follows: 
  

	 	(a)	No amendment shall reduce the value of a Participant’s benefits to less than the amount he would be entitled to receive if he had resigned from the employ of all of the Employers on the date of the amendment; and



  
 46 









	 	(b)	Except as provided elsewhere in the Plan, under no condition shall an amendment result in the return or repayment to any Employer of any part of the Trust Fund or the income from it or result in the distribution of the
Trust Fund for the benefit of anyone other than persons entitled to benefits under the Plan. Notwithstanding the foregoing, the Company, or its delegate, shall have the duty and power revise the Plan, Supplements, Exhibits or Appendices, as well as
addenda or amendments thereto, to correct errors, including but not limited to scrivener’s errors, to the extent such correction is necessary to reflect the intent of the Plan; provided that such correction shall be applied as if included in
the original provisions. 

 11.02 Termination. The Plan will terminate as to all Employers on any date specified by the
Company (in accordance with the procedures set forth in Section 10.11). The Plan will terminate as to an individual Employer on the first to occur of the following: 
  

	 	(a)	The date it is terminated by that Employer (in accordance with the procedures set forth in Section 10.07) if 30 days advance written notice of the termination is given to the Company, the Trustee and other
Employers. 

  

	 	(b)	The date that Employer is judicially declared bankrupt or insolvent. 

  

	 	(c)	The date that either the Company completely discontinues contributions under the Plan on behalf of that Employer or that Employer completely discontinues contributions under the Plan. 


 

	 	(d)	The dissolution, merger, consolidation or reorganization of that Employer, or the sale by the Company or that Employer of all or substantially all of that Employer’s assets, except that: 


 

	 	(1)	in any such event, arrangements may be made with the consent of the Company whereby the Plan will be continued by any successor to that Employer or any purchaser of all or substantially all of its assets, in which case
the successor or purchaser will be substituted for that Employer under the Plan and the Trust Agreement; and 

  

	 	(2)	if an Employer is merged, dissolved, or in any other way reorganized into, or consolidated with, any other Employer, the Plan as applied to the former Employer will automatically continue in effect without a termination
thereof. 

 11.03 Vesting and Distribution on Termination. On termination or partial termination of the Plan, the date
of termination will be a “special accounting date” and, after all adjustments then required have been made, each affected Participant’s benefits will be nonforfeitable and will be distributable to the Participant or his or her
beneficiary in accordance with the provisions of Article VIII. 

  
 47 








 11.04 Notice of Amendment or Termination. Participants will be notified of an amendment or
termination of the Plan in accordance with applicable law. 
 11.05 Plan Merger, Consolidation, etc.. In the case of any merger or
consolidation with, or transfer of assets or liabilities to, any other plan, each Participant’s benefits if the Plan terminated immediately after such merger, consolidation or transfer shall be equal to or greater than the benefits he would
have been entitled to receive if the Plan had terminated immediately before the merger, consolidation or transfer. 
 ARTICLE XII 

SPECIAL RULES FOR TOP-HEAVY PLANS 

12.01 Purpose and Effect. The purpose of this Article XII is to comply with the requirements of Section 416 of the Code. The
provisions of this Article XII shall be effective for each Plan Year in which the Plan is a “top-heavy plan” within the meaning of Section 416(g) of the Code. Notwithstanding anything to the contrary, the Plan shall be governed by the
then in effect Code Section 416 in the event the Plan is a “top-heavy plan” within the meaning of Code Section 416 for any given Plan Year. 

12.02 Top-Heavy Plan. 
  

	 	(a)	In general, the Plan will be a top-heavy plan for any Plan Year if, as of the last day of the preceding Plan Year (the “determination date”), the present value of accrued benefits of Participants who are key
employees (as defined in Section 416(i)(1) of the Code) to the present value of accrued benefits of all Participants exceeds 60% taking into account all distributions made during a 1-year period ending on the most recent determination date and
not taking into account any accrued benefit or Account balance of an individual who has not performed services for an Employer during a 1-year period ending on the determination date, except that in the case of a distribution made for a reason other
than severance from employment, death or disability, this provision shall be applied by substituting “5-year period” for “1-year period.” 

  

	 	(b)	 Distributions during year ending on the determination date. The present values of accrued benefits and the amounts of Account balances of an
Employee as of the determination date shall be increased by the distributions made with respect to the Employee under the Plan and any plan aggregated with the Plan under Section 416(g)(2) of the Code during the 1-year period ending on the
determination date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Section 416(g)(2)(A)(i) of the Code. In the case of a
distribution 



  
 48 









	 	
made for a reason other than severance from employment, death, or Disability, this provision shall be applied by substituting “5-year period” for “1-year period.”


  

	 	(c)	Employees not performing services during year ending on the determination date. The accrued benefits and Accounts of any individual who has not performed services for an Employer during the 1-year period ending
on the determination date shall not be taken into account. 

  

	 	(d)	Matching contributions. Employer Matching Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) of the Code and the Plan. The
preceding sentence shall apply with respect to Employer Matching Contributions under the Plan or, if the Plan provides that the minimum contribution requirement shall be met in another plan, such other plan. Employer Matching Contributions that are
used to satisfy the minimum contribution requirements shall be treated as matching contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code. 


12.03 Key Employee. Key employee means any Employee or former Employee (including any deceased Employee) who at any time during the
Plan Year that includes the determination date was an officer of an Employer having annual compensation greater than $170,000 (as adjusted under Section 416(i)(1) of the Code for Plan Years beginning on or after January 1, 2016), a 5-percent owner of an Employer, or a 1-percent owner of an Employer having annual compensation of more than $150,000. For this purpose, annual compensation means compensation within the meaning of
Section 415(c)(3) of the Code. In all cases, the determination of who is a key employee will be made in accordance with Section 416(i)(1) of the Code and the applicable regulations and other guidance of general applicability issued
thereunder. 
 12.04 Minimum Vesting. For any Plan Year in which the Plan is a top-heavy plan, a Participant shall be 100% vested in
his or her Employer Contributions after three years of Continuous Service. If the foregoing provisions of this Section 12.04 become effective, and the Plan subsequently ceases to be a top-heavy plan, each Participant who has then completed
three or more years of service may elect to continue to have the vested percentage of his or her Employer Contributions determined under the provisions of this Section 12.04. 

12.05 Minimum Employer Contribution. For any Plan Year in which the Plan is a top-heavy plan, the Employer contributions and
forfeitures, if any, credited to each Participant who is not a key employee shall not be less than 3 percent of such Participant’s Compensation for that year. In no event, however, shall the Employer Contribution credited in any year to a
Participant who is not a key employee exceed the maximum Employer Contribution credited in that year to a key employee (expressed as percentage of such key employee’s compensation). 

  
 49 








 12.06 Aggregate of Plans. In accordance with Section 416(g)(2) of the Code, other
plans maintained by the Employers may be required or permitted to be aggregated with this Plan for purposes of determining whether the Plan is a top-heavy plan. 

For purposes of determining whether the Plan is a top-heavy plan for a particular Plan Year, the required aggregation group includes each plan of the Employer
in which a key employee participates (in the Plan Year containing the determination date or any of the four preceding Plan Years) and each other plan which enables any plan in which a key employee participates during the period tested to meet the
requirements of Code Sections 401(a)(4) or 410(b). A permissive aggregation group consists of the plans of the Employer that are required to be aggregated, plus one or more plans of the Employer that are not part of the required aggregation group
but that satisfy the requirements of Code Sections 401(a)(4) and 410(b) when considered together with the required aggregation group. 

12.07 No Duplication of Benefits. If the Employers maintain more than one plan, the minimum Employer Contribution otherwise required
under Section 12.05 above may be reduced in accordance with regulations of the Secretary of the Treasury to prevent inappropriate duplication of minimum contributions or benefits. 

12.08 Adjustment of Combined Benefit Limitations. To the extent required under applicable law only, for any Plan Year in which the Plan
is a top-heavy plan, the determination of the defined contribution plan fraction and defined benefit plan fraction in accordance with Section 415 of the Code and Section 1106 of the Tax Reform Act of 1986 shall be adjusted in accordance
with the provisions of Section 416(h) of the Code. 
 12.09 Use of Terms. All terms and provisions of the Plan shall apply to
this Article XII, except that where the terms and provisions of the Plan and this Article XII conflict, the terms and provisions of this Article XII shall govern. 

ARTICLE XIII 
 HEART
ACT PROVISIONS 
 13.01 Death Benefits. Notwithstanding any provision of the Plan to the contrary, in the case
of a Participant who dies while performing Qualified Military Service (as defined in Code Section 414(u)), the Participant’s Beneficiary is entitled to any additional benefits (other than benefit accruals relating to the period of
qualified military service) provided under the Plan as if the Participant had resumed and then terminated employment on account of death. The Plan will credit the Participant’s Qualified Military Service as service for purposes of vesting as
though the Participant had resumed employment under the Uniformed Services Employment and Reemployment Rights Act (USERRA) immediately prior to the Participant’s death. 

13.02 Differential Wage Payments. Notwithstanding any provision of the Plan to the contrary, (i) a Participant
receiving a differential wage payment (as defined in Code Section 3401(h)(2)) shall be treated as an Employee, (ii) the differential wage payment shall be treated as compensation for Code Section 415(c)(3) purposes and for Treasury
Regulations 

  
 50 








 
Section 1.415-2(d) purposes, as well as for purposes of determining the Employer Contributions to which the Participant is entitled under the terms of the Plan, and (iii) the Plan shall
not be treated as failing to meet the requirements of any provision described in Code Section 414(u)(1)(C) by reason of any contribution or benefit which is based on the differential wage payment. Section 13.02(iii) will only apply to the
