 ARTICLE I 

TITLE AND DEFINITIONS 

1.1. Title and History. 

This Plan shall be known as the “Science Applications International Corporation 401(k) Excess Deferral Plan.” 

All Participants and their Beneficiaries having an undistributed interest in the Leidos, Inc. Retirement Plan (previously known as the Science
Applications International Corporation Retirement Plan) immediately prior to September 27, 2013 shall, on and after September 27, 2013, be entitled to benefits provided solely from this Plan, in lieu of any and all interest which they had
or may have had under the Leidos, Inc. Retirement Plan, and the rules governing distribution of such interests under the Leidos, Inc. Retirement Plan as well as any outstanding deferral elections under the Leidos, Inc. Retirement Plan made by a
Participant shall remain in effect except to the extent amended in accordance with the terms of this Plan. Without limiting the generality of the foregoing, Beneficiary designations under the Leidos, Inc. Retirement Plan shall continue to apply to
the Accounts. 
 1.2. Definitions. 

Whenever the following words and phrases are used in this Plan, with the first letter capitalized, they shall have the meanings specified
below. 
 “Account” or “Accounts” shall mean a Participant’s Deferral Account and Matching Account. The Committee
may establish such additional accounts or subaccounts as it deems necessary for the proper administration of the Plan. Accounts are established under the Plan for recordkeeping purposes only, and do not contain or represent actual assets. 

“Annual 401(k) Matching Amount” shall mean the amount of the Company’s matching contribution credited to a Participant’s
account in the 401(k) Plan for a Plan Year. 

 “Beneficiary” or “Beneficiaries” shall mean the person or persons, including
a trustee, personal representative or other fiduciary, who have been designated by the Participant to receive the benefits specified hereunder in the event of the Participant’s death. The Participant shall make such designation on a form
provided by the Committee or on such terms and conditions as the Committee may prescribe for a Beneficiary designation. No such Beneficiary designation shall become effective until it is filed with the Committee. Such Beneficiary designation shall
thereafter remain in effect with respect to this Plan until a new Beneficiary designation is filed with the Committee pursuant to the terms hereof. A Participant may from time to time change his or her designated Beneficiary or Beneficiaries without
the consent of such Beneficiary or Beneficiaries by filing a new designation in writing with the Committee. If the designated Beneficiary does not survive the Participant, or if there is no valid Beneficiary designation, amounts payable under the
Plan shall be paid to the Participant’s spouse, or if there is no surviving spouse, then to the duly appointed and currently acting personal representative of the Participant’s estate. If there is no personal representative of the
Participant’s estate duly appointed and acting in that capacity within sixty (60) days after the Participant’s death, then all payments due under the Plan shall be payable to the person or persons who can verify by affidavit or court
order to the satisfaction of the Committee that they are legally entitled to receive the benefits specified hereunder pursuant to the laws of intestate succession or other statutory provisions in effect at the Participant’s death in the state
in which the Participant resided. In the event any amount is payable under this Plan to a minor, payment shall not be made to the minor, but instead shall be paid (i) to that person’s living parent(s) to act as custodian, (ii) if that
person’s parents are then divorced, and one parent is the sole custodial parent, to such custodial parent, or (iii) if no parent of that person is then living, to a custodian 

  
 2 

 
selected by the Committee to hold the funds for the minor under the Uniform Transfers of Gifts to Minors Act in effect in the jurisdiction in which the minor resides. If no parent is living and
the Committee decides not to select another custodian to hold the funds for the minor, then payment shall be made to the duly appointed and currently acting guardian of the estate for the minor or, if no guardian of the estate for the minor is duly
appointed and currently acting within sixty (60) days after the date the amount becomes payable, payment shall be deposited or made with the court having jurisdiction over the estate of the minor. 

“Board of Directors” or “Board” shall mean the Board of Directors of Science Applications International Corporation, or
its parent corporation. 
 “Change in Control” of the Company shall mean the following for purposes of this Plan and shall be
deemed to occur if any “person,” (as defined in Section 3(a)(9) of the Exchange Act), other than the Company, any subsidiary or any employee benefit plan or trust maintained by the Company or subsidiary becoming the beneficial owners
(as defined in Rule 13d-3 under the Exchange Act), directly to indirectly, of more than thirty-five percent (35%) of the common stock of the Company outstanding at such time, without the prior approval of the Board. For purposes of the
foregoing, a subsidiary is any corporation in an unbroken chain of corporations beginning with the Company if each of the corporations, other than the last corporation in such chain, owns at least fifty percent (50%) of the total voting power
in one of the other corporations in such chain. The above definition of Change in Control shall be applied in accordance with Code Section 409A. 

“Code” shall mean the Internal Revenue Code of 1986, as amended. 

“Committee” shall mean the committee composed of such members as shall be appointed from time to time by the Board to administer the
Plan.

corporation). In addition, unless the context indicates otherwise, as used in this Plan the term Company shall also mean and include any direct or indirect subsidiary of the Company which has been approved by the Board for participation in this Plan
by its employees. Upon and after a Change in Control, Company shall include any successor to Science Applications International Corporation or its parent corporation or a substantial portion of their assets. 

“Deferral Account” shall mean the bookkeeping account maintained by the Company on behalf of a Participant who elects to defer his
or her Salary in cash under this Plan pursuant to Section 3.1. 
 “Eligible Employee” shall mean a highly compensated
employee of the Company who has been selected by the Board to participate in this Plan. The Board shall limit Eligible Employee status to a select group of management or highly compensated employees, as set forth in Sections 201, 301 and 401 of
ERISA. The Board may make its determination of Eligible Employees by establishing eligibility criteria such as title or compensation level. 

“ERISA” shall mean the Employee Retirement Income Security Act of 1974, as amended. 

“Exchange Act” shall mean the Securities Exchange Act of 1934, as amended from time to time. 

“401(k) Plan” means the Science Applications International Corporation Retirement Plan as it may be amended from time to time. 

“Investment Funds” shall mean the deemed investments established by the Committee under Section 4.3 for the purpose of
determining the investment gains and losses to be credited to Accounts. 

  
 4 

 “Matching Account” shall mean the bookkeeping account maintained by the Company on
behalf of each Participant pursuant to Section 4.2 to reflect the Participant’s interest in the Plan attributable to the Company’s matching credits. 

“Participant” shall mean any Eligible Employee who elects to defer a portion of his or her Salary in accordance with
Section 3.1 and who satisfies the participation requirements of Article II. 
 “Plan” shall mean the Science Applications
International Corporation 401(k) Excess Deferral Plan set forth herein, as it may be amended from time to time. This Plan constitutes an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of
management or highly compensated employees, as set forth in Sections 201, 301 and 401 of ERISA. 
 “Plan Year” shall mean each
twelve (12) consecutive month period beginning on January 1. 
 “Salary” shall mean the amount of compensation paid as
salary by the Company during a calendar year by reason of services performed by a Participant reflected as “wages, tips, other compensation” on the Participant’s Form(s) W-2 for such year; 

(i) plus elective deferrals under Code Section 402(g)(3), catch-up contributions under Code Section 414(v), and
amounts contributed under Code Sections 125 and 132(f) by the Company at the Participant’s election that are not included in the Participant’s gross income (but only to the extent such deferrals and contributions were made by reducing
salary otherwise payable to the Participant); plus 
 (ii) Any compensation paid as salary which, but for Code
Section 3401(a)(8)(A) (dealing with the Code Section 911 exclusion and income subject to foreign withholding) would be required to be reflected as “wages, tips, other compensation” on the Participant’s Form(s) W-2; less 

  
 5 

 (iii) Any compensation paid by reason of services performed during any period in
which an employee is not a Participant; overtime pay (which shall be deemed to include base pay and premium pay for time worked in excess of a normal day or week); bonuses; commissions; and amounts reflecting reimbursed expenses or fringe benefits
(including any amount relating to the grant or exercise of stock options, disposition of shares through exercise of options, payment of dividends on non-vested stock, payments representing dividends or dividend equivalents on stock units or stock
rights, and any distributions from a plan of deferred compensation) which have been included as “wages, tips, compensation” on the Participant’s Form(s) W-2. 

“Separation from Service” means, the death, retirement or termination of the Eligible Employee’s employment with the Company,
whether voluntarily or involuntarily. This definition of Separation from Service shall be interpreted and construed in a manner intended to comply with Code Section 409A and Treasury Regulation Section 1.409A-1(h). 

“Trust” shall mean a grantor trust established and funded by the Company for the purpose of satisfying some or all of the
Company’s obligations under the Plan. 
 “Trustee” shall mean the trustee of the Trust. 

ARTICLE II 

PARTICIPATION 
 2.1.
Participation. 
 Elective deferrals under this Plan are voluntary. Only Eligible Employees may participate in this Plan. An
Eligible Employee shall become a Participant in this Plan by electing 

  
 6 

 
to defer a portion of his or her Salary in accordance with Article III. Notwithstanding anything else contained herein to the contrary, an Eligible Employee shall be permitted to defer a portion
of his or her Salary to this Plan during a particular Plan Year only after the Eligible Employee is prohibited from making any additional elective deferrals to the 401(k) Plan during such Plan Year because the elective deferrals (a) would
exceed the amount specified in Code Section 402(g), (b) would cause the 401(k) Plan to fail to satisfy the limitation of Code Section 401(k)(3), or would increase the margin by which the 401(k) Plan fails to satisfy the limitation of
Code Section 401(k)(3), or (c) would otherwise exceed the maximum elective deferrals permitted under the terms of the 401(k) Plan. 

An Eligible Employee who is eligible to make catch-up contributions (as described in Code Section 414(v)) under the 401(k) Plan shall be
permitted to defer compensation under this Plan for a Plan Year only if the Eligible Employee satisfies the requirements of this Article II and has made all such catch-up contributions under the 401(k) Plan for such Plan Year. 

ARTICLE III 
 DEFERRAL
ELECTIONS 
 3.1. Deferral Elections. 

(a) Salary Deferral Elections. The Committee shall notify each Eligible Employee of his or her eligibility to participate in the Plan.
An Eligible Employee’s elections to participate may be made by electronic means in accordance with rules and procedures established by the Committee. 

(b) No Bonus Deferrals. Notwithstanding any other provision herein, no Eligible Employee shall be permitted to defer any bonus under
this Plan. 

  
 7 

 (c) Timing of Deferral Election. To participate through the deferral of Salary for any
Plan Year, an Eligible Employee must file an election in accordance with procedures established by the Committee no later than the date in the preceding Plan Year determined by the Committee. Such date shall precede the first day of the Plan Year
during which the deferral election shall be effective for the deferral of Salary. 
 (d) Newly Hired Employee. An Eligible Employee
whose employment with the Company commences during a Plan Year shall not be permitted to participate until the first day of the following Plan Year. 

(e) Method of Deferral. Each deferral election shall specify the portion of the Eligible Employee’s Salary that he or she elects
to defer. An election to defer Salary for a Plan Year shall apply to all Salary earned during each pay period that ends during such Plan Year. 

(f) Amount of Deferrals. The amount of Salary that an Eligible Employee may elect to defer is any percentage (in one percent
(1%) increments) up to twenty percent (20%); provided, however, that no election shall be effective to reduce the Salary payable to an Eligible Employee for a calendar year to an amount which is less than the amount that the Company is required
to withhold from such Eligible Employee’s Salary for such calendar year for purposes of federal, state and local (if any) income tax, employment tax (including without limitation Federal Insurance Contributions Act (FICA) tax), and other tax
withholdings. Deferral of the percentage of Salary elected by the Eligible Employee shall commence with the pay period following the pay period in which the Eligible Employee’s elective deferrals under the 401(k) Plan for the Plan Year reach
the limit on elective deferrals under Code Section 402(g) (increased, if applicable, by the limit on catch-up contributions under Code Section 414(v)). 

  
 8 

 (g) Duration of Deferral Election. Any deferral election made under paragraphs (c) or
(d) shall remain in effect and, except as provided in Subsection 3.1(h), be irrevocable, notwithstanding any change in the Participant’s Salary, for the entire Plan Year for which it is effective. A new deferral election must be made for
each subsequent Plan Year prior to the commencement of such subsequent Plan Year. 
 (h) Emergency Cessation of Deferrals.
Notwithstanding anything else contained herein to the contrary, a Participant may discontinue his or her Salary deferrals under the Plan at any time if the Committee determines that the Participant has an Unforeseeable Emergency as defined in
Section 6.3(b), or a hardship distribution from the 401(k) Plan pursuant to Treasury Regulation 1.401(k)-1(d)(3). Such discontinuance of deferrals will remain in effect for the remainder of the current Plan Year. 

3.2. Coordination with 401(k) Plan Election. 

Participants shall make separate elections of the percentage deferrals under this Plan and the 401(k) Plan. 

ARTICLE IV 
 ACCOUNTS

 4.1. Deferral Account. 

The Committee shall establish and maintain a Deferral Account for each Participant under the Plan. Notwithstanding anything else contained
herein to the contrary, the Committee and the administrator of the 401(k) Plan shall have full power and authority to determine whether amounts of the Participant’s Salary that the Participant elected to be deferred to the 401(k) Plan for a
Plan Year will instead be deferred under this Plan or not deferred under either this Plan or the 401(k) Plan. 

  
 9 

 Subject to the requirements of Article II, as soon as administratively practical after submission
of each pay period report, the Plan’s recordkeeper shall credit the Participant’s Deferral Account with an amount equal to the portion of Salary deferred by the Participant during the pay period in accordance with the Participant’s
election under Sections 3.1 and 3.2; that is, the portion of the Participant’s Salary that the Participant has elected to be deferred and has been determined by the Committee to be deferred under his or her Deferral Account. 

4.2. Matching Account. 

The Committee shall establish and maintain a Matching Account for each Participant who receives a matching credit under the Plan. Subject to
the requirements of Article II, as soon as administratively practical after submission of the final pay period report for each Plan Year, for any Participant who continues to be an employee of the Company on the last business day of the Plan Year,
the Plan’s recordkeeper shall credit a Participant’s Matching Account with an amount, if any, equal to the difference between his or her actual Annual 401(k) Matching Amount and the amount the Annual 401(k) Matching Amount would have been
had Participant not deferred his or her Salary under this Plan for the Plan Year. 
 4.3. Investment of Accounts. 

(a) Separate Investment Funds shall be established under this Plan. The Committee may, in its discretion, terminate any Investment Fund. The
Committee shall determine the number of Investment Funds, and the Committee or its delegate shall determine the investments to be made under the Investment Funds. 

(b) Pursuant to rules established by the Committee, each Participant shall have the right and obligation to designate in which of the
Investment Funds his or her Accounts will be deemed to be invested for purposes of determining the investment gain (or loss) to be 

  
 10 

 
credited to his or her Accounts. Pursuant to rules established by the Committee, a Participant may change the designation made under this Section 4.3 and/or transfer an amount deemed to be
invested in one Investment Fund to another Investment Fund by filing an election with the Committee, on a form and in a manner prescribed by the Committee, prior to any deadline that may be established by the Committee. If a Participant does not
make an election with respect to the investment of his or her Account, the Participant shall be deemed to have elected a default Investment Fund determined by the Committee. The Committee may establish other rules, regulations and procedures
regarding the Investment Funds as it deems appropriate in its sole discretion. 
 (c) Investment Funds are designated only for the purpose
of determining the investment gains and losses to be credited on Participants’ Accounts. Neither the Company nor the Trust is required to make actual investments corresponding to such Investment Funds. 

ARTICLE V 
 VESTING

 5.1. Vesting. 

(a) Deferral Account. A Participant’s Deferral Account shall be one hundred percent (100%) vested at all times. 

(b) Matching Account. The Participant’s Matching Account shall vest as follows: 

 

						
	 Years of Service
	  	Vested Interest
	 Less than one year
	  	 	 	0	%
	 One year but less than two years
	  	 	 	20	%
	 Two years but less than three years
	  	 	 	40	%
	 Three years but less than four years
	  	 	 	60	%
	 Four years but less than five years
	  	 	 	80	%
	 Five years or more
	  	 	 	100	%

  
 11 

 A “Year of Service” is any calendar year in which a Participant completes at least
eight hundred fifty (850) hours of service for the Company and continues to be an employee of the Company on the last business day of the Plan Year, including service in years prior to the establishment of this Plan. 

Notwithstanding the above schedule, a Participant’s Matching Account shall become one hundred percent (100%) vested if, during a
Participant’s period of employment with the Company (including periods while on an approved leave of absence, or, in the case of the Participant’s death while performing ‘qualified military service’ as defined in Code
Section 414(u)), there is a Change in Control, the Participant dies, is Disabled (as determined under the 401(k) Plan), reaches age 59  1⁄2 or is
judicially declared to be incompetent. Any amount not vested upon a Participant’s Separation from Service is immediately forfeited. 

ARTICLE VI 

DISTRIBUTIONS 
 6.1.
Distribution of Accounts. 
 (a) Time of Distribution. Distribution of a Participant’s Accounts under the Plan shall
be made (or if installments are paid under § 6.1(b)(ii), shall commence to be made) within ninety (90) days following his or her Separation from Service or as soon as administratively feasible thereafter. Notwithstanding the
foregoing, if any stock of the Company is publicly traded on an established securities market, the distribution to any Participant who is a “specified employee” under Code Section 409A(a)(1)(B)(i) shall not be made (or commence to be
made in the case of installment payments) before the earlier of (i) the date which is six (6) months after such Participant’s Separation from Service or (ii) the date of the Participant’s death.

  
 12 

 
For any twelve (12) month period commencing April 1 and ending March 31, an Eligible Employee is a “specified employee” if the Eligible Employee was a “key
employee” at any time during the calendar year ending before such April 1. A key employee is defined in Code Section 416(i) without regard to Code Section 416(i)(5). 

(b) Manner of Distribution. The amount to be paid to the Participant shall be the entire vested amount credited to the
Participant’s Accounts. 
 (i) Amounts shall be paid in cash in a lump sum and valued as of the date the amount of the
distribution is determined. 
 (ii) Notwithstanding Section 6.1(b)(i) above, if elected by the Participant prior to his
or her participation in the Plan, the Participant shall receive his or her payment in the form of annual installments, over a period not to exceed ten (10) years. If a Participant dies during the payout period, any amounts remaining in the
Participant’s Accounts shall be paid in a lump sum as soon as administratively practical to the Participant’s Beneficiary. 

(iii) Except as set forth in this Section, a Participant’s election of form of distribution shall be irrevocable. Each of
the forms of distribution set forth in Sections 6.1(b)(i) and (ii) shall be considered a single payment for purposes of Code Section 409A. Accordingly, Participants shall be allowed to make a new form of distribution election, provided
that the following requirements are satisfied: 
 (a) The election does not take effect until at least twelve
(12) months after the date the election is made, and the election must be made at least twelve (12) months prior to the date the first payment would be made to the Participant absent the election; 

  
 13 

 (b) The commencement date of the first payment to the Participant shall be five
(5) years following the date the payment would have commenced absent the change in the Participant’s election; and 

(c) No Participant may make more than one (1) new form of distribution election. 

Any attempt to change a payout election that does not satisfy these requirements shall be void. 

6.2. Inability to Locate Participant. 

In the event that the Committee is unable to locate a Participant or Beneficiary within two (2) years following the date the Participant
was to commence receiving payment or delivery pursuant to Section 6.1 the entire amount allocated to the Participant’s Accounts shall be forfeited. Furthermore, if any benefit payment (by check or other form of payment) to a Participant or
Beneficiary remains uncashed or unclaimed for two (2) years following its delivery to the last known address of the Participant or Beneficiary, the amount of such benefit payment shall be forfeited. Any forfeited amount shall immediately become
the property of the Company. If, after such forfeiture, the Participant or Beneficiary later claims such benefit, such benefit shall be reinstated without interest or earnings, from the date of the forfeiture. The distribution of such benefits shall
thereafter be made in the manner determined by the Committee. 

  
 14 

 6.3. Unforeseeable Emergencies. 

(a) General. A Participant (or former Participant or Beneficiary) may request a distribution from the vested portion of his or her
Account for an Unforeseeable Emergency without penalty. Such distribution for an Unforeseeable Emergency shall be subject to approval by the Committee and may be made only to the extent reasonably necessary to satisfy the emergency need (which may
include amounts necessary to pay any federal, state or local income taxes or penalties reasonably anticipated to result from the distribution). A distribution for an Unforeseeable Emergency may not be made to the extent that such emergency is or may
be relieved (1) through reimbursement or compensation by insurance or otherwise, (2) by liquidation of the Participant’s (or Beneficiary’s) assets, to the extent the liquidation of such assets would not itself cause severe
financial hardship, or (3) by cessation of deferrals under this Plan. The Committee may require that the Participant (or Beneficiary) provide a written representation that any such distribution satisfies the requirements set forth in this
Section 6.3(a). 
 (b) Definition of Unforeseeable Emergency. An “Unforeseeable Emergency” with respect to a
Participant shall mean a severe financial hardship to the Participant resulting from an illness or accident of the Participant, the Participant’s spouse, the Participant’s Beneficiary or the Participant’s dependent (as defined in Code
Section 152, without regard to Code Section 152(b)(l), (b)(2) and (d)(1)(B)), loss of the Participant’s property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the
control of the Participant. The circumstances that will constitute an Unforeseeable Emergency will depend upon the facts of each case and in all events must constitute an “unforeseeable emergency” within the meaning of Code
Section 409A. The purchase of a home and the payment of college tuition would typically not be considered to be Unforeseeable Emergencies. 

  
 15 

 (c) Administrative Provisions for Withdrawals. Distributions under this Section 6.3
shall first be made from the Deferral Account and after it is exhausted, from the vested portion of the Matching Account. Such distributions will be made as soon as administratively practical following the Participant’s submission of a
completed withdrawal form. 
 6.4. Distributions on Death. 

In the event of the death of a Participant, the Participant’s Accounts shall be paid to the Participant’s Beneficiary in a lump sum
as soon as administratively practical following the Participant’s death. 
 6.5. Change in Control. 

Upon a Change in Control at the Company, all Accounts shall be distributed as soon as administratively practical after the Change in Control.
Following a Change in Control, no amendment or termination of the Plan shall adversely affect any benefits earned by Participants prior to the amendment or termination. 

6.6. Incapacity. 

If the Committee shall find that any person to whom any payment is payable under this Plan is unable to care for his or her affairs because of
illness or accident, a payment due (unless a prior claim therefore shall have been made by a duly appointed guardian or other legal representative) may be paid to the spouse, a child, a parent, or a brother or sister, or to any custodian,
conservator or other fiduciary responsible for the management and control of such person’s financial affairs in such manner and proportions as the Committee may determine. Any such payment shall, to the extent thereof, discharge of the
liabilities of the Company to the Participant or Beneficiary under this Plan. 

  
 16 

 6.7. Construction. 

For purposes of this Article VI, a payment shall be considered to have been made “as soon as administratively practical after” a
particular date only if it is made within ninety (90) days after that date. 
 ARTICLE VII 

CLAIMS PROCEDURE AND ARBITRATION 

7.1. Claims Procedure and Arbitration. 

(a) The Committee shall establish procedures for action upon claims initially made and the communication of a decision to the claimant
promptly and, in any event, not later than sixty (60) days after the date of the claim; the claim may be deemed by the claimant to have been denied for purposes of further review described below in the event a decision is not furnished to the
claimant within such sixty (60) day period. Every claim for benefits which is denied shall be denied by written notice setting forth in a manner calculated to be understood by the claimant (1) the specific reason or reasons for the denial,
(2) specific reference to any provisions of this Plan on which denial is based, (3) description of any additional material or information necessary for the claimant to perfect his claim with an explanation of why such material or
information is necessary, and (4) an explanation of the procedure for further reviewing the denial of the claim under the Plan. The Committee shall establish a procedure for review of claim denials, such review to be undertaken by the
Committee. The review given after denial of any claim shall be a full and fair review with the claimant or his duly authorized representative having one hundred eighty (180) days after receipt of denial of his claim to request such review,
having the right to review all pertinent documents and the right to submit issues and comments in writing. The Committee shall establish a procedure for issuance of a decision by the Committee not later than sixty (60) days after receipt of a
request for review 

  
 17 

 
from a claimant unless special circumstances, such as the need to hold a hearing, require a longer period of time, in which case a decision shall be rendered as soon as possible but not later
than one hundred twenty (120) days after receipt of the claimant’s request for review. The decision on review shall be in writing and shall include specific reasons for the decision written in a manner calculated to be understood by the
claimant with specific reference to any provisions of this Plan on which the decision is based. 
 (b) Any person disputing a decision of
the Committee shall submit such dispute to binding arbitration pursuant to the rules of the American Arbitration Association, to be held in Fairfax County, Commonwealth of Virginia. In any arbitration with respect to a decision or action of the
Committee taken before a Change in Control, the losing party in such arbitration proceedings shall bear the costs of arbitration, and each party shall bear its own attorneys’ fees. In any arbitration with respect to a decision or action of the
Committee taken after a Change in Control, the Company shall bear the costs of arbitration (other than attorneys’ fees), and the arbitrator may make an award of attorneys’ fees; any such award shall be made according to the then-prevailing
standards for judicial awards of attorneys’ fees applicable to civil actions brought under the Employee Retirement Income Security Act of 1974, as amended. 

ARTICLE VIII

 8.1.
Committee. 
 The Committee shall be appointed by, and serve at the pleasure of, the Board of Directors. 

  
 18 

 8.2. Committee Action. 

The Committee shall act at meetings by affirmative vote of a majority of the members of the Committee. Any action permitted to be taken at a
meeting may be taken without a meeting if, prior to such action, a written consent to the action is signed by all members of the Committee and such written consent is filed with the minutes of the proceedings of the Committee. A member of the
Committee shall not vote or act upon any matter which relates solely to himself or herself as a Participant. The chairman of the Committee (the “Chairman”) or any other member or members of the Committee designated by the Chairman may
execute any certificate or other written direction on behalf of the Committee. 
 8.3. Powers and Duties of the Committee.

 Subject to Section 8.4, the Committee, on behalf of the Participants and their Beneficiaries, shall enforce this Plan in
accordance with its terms, shall be charged with the general administration of this Plan, and shall have all powers necessary to accomplish its purposes, including, but not by way of limitation, the following: 

(a) Prior to a Change in Control, to construe and interpret the terms and provisions of the Plan; provided that upon and after a Change in
Control, the Committee’s interpretation or construction (and any previous interpretation or construction of the Committee) shall be reviewed on a de novo basis; 

(b) To compute and certify to the amount and kind of benefits payable or deliverable to Participants and their Beneficiaries; 

(c) To maintain all records that may be necessary for the administration of this Plan; 

  
 19 

 (d) To provide for the disclosure of all information and the filing or provision of all reports
and statements to Participants, Beneficiaries or governmental agencies as shall be required by law; 
 (e) To make and publish such rules
for the regulation of this Plan and procedures for the administration of this Plan as are not inconsistent with the terms hereof; 
 (f) To
appoint a plan administrator or any other agent, and to delegate to them such powers and duties in connection with the administration of this Plan as the Committee may from time to time prescribe; and 

(g) To direct the Trustee concerning the performance of various duties and responsibilities under the Trust. 

8.4. Interpretation of Plan. 

Prior to the occurrence of a Change in Control, the Committee shall have full discretion to construe and interpret the terms and provisions of
this Plan, which interpretation or construction shall be final and binding on all parties, including but not limited to the Company and any Participant or Beneficiary. The Committee shall administer such terms and provisions in a uniform and
nondiscriminatory manner and in full accordance with any and all laws applicable to this Plan. Notwithstanding the foregoing, after the occurrence of a Change in Control, no deference shall be given to the Committee’s construction or
interpretation (or the Committee’s prior interpretation or construction) of the Plan and any such construction or interpretation shall be reviewed under a de novo standard of review. 

In making any determination or in taking or not taking any action under this Plan, the Committee, or the Board, as the case may be, may obtain
and may rely upon the advice of experts, including professional advisors to the Company. No Director, officer or agent of the Company shall be liable for any such action or determination taken or made or omitted in good faith. 

  
 20 

 8.5. Plan Construction. 

It is the intent of the Company that a Participant’s deferrals of Salary and matching contributions under the Plan shall not be
considered conditioned on the Participant’s participation in the 401(k) Plan in accordance with Treasury Regulation Section 1.401(k)- 1(e)(6)(iv), and this Plan shall be interpreted consistent with such intent. 

8.6. Information. 

To enable the Committee to perform its functions, the Company shall, upon request of the Committee, supply full and timely information to the
Committee on all matters relating to the Salary of all Participants, their death, or other cause of termination, and such other pertinent facts as the Committee may require. 

8.7. Compensation, Expenses and Indemnity. 

(a) The Committee is authorized at the expense of the Company to employ such legal counsel and administrative services as it may deem
advisable to assist in the performance of its duties hereunder. Expenses and fees in connection with the administration of this Plan shall be paid by the Company. 

(b) To the extent permitted by applicable state law, the Company shall indemnify and save harmless the Committee and each member thereof, the
Board of Directors and any delegate of the Committee who is an employee of the Company against any and all expenses, liabilities and claims, including legal fees to defend against such liabilities and claims arising out of their discharge in good
faith of responsibilities under or incident to this Plan, other 

  
 21 

 
than expenses and liabilities arising out of willful misconduct. This indemnity shall not preclude such further indemnities as may be available under insurance purchased by the Company or
provided by the Company under any bylaw, agreement or otherwise, as such indemnities are permitted under state law. 
 ARTICLE IX 

MISCELLANEOUS 
 9.1.
Unsecured General Creditor. 
 Participants and their Beneficiaries, heirs, successors, and assigns shall have no legal or
equitable rights, claims, or interest in any specific property or assets of the Company. No assets of the Company shall be held under any trust (other than a grantor trust within the meaning of Code Section 671, et. seq.), or held in any way as
collateral security for the fulfilling of the obligations of the Company under this Plan. The Company’s obligation under this Plan shall be merely that of an unfunded and unsecured promise of the Company to pay money in the future, and the
rights of the Participants and Beneficiaries shall be no greater than those of unsecured general creditors. 
 9.2. No Employment
Contract. 
 Nothing contained in this Plan (or in any other documents related to this Plan) shall confer upon any Eligible Employee
or other Participant any right to continue in the employ or other service of the Company or constitute any contract or agreement of employment or other service, nor shall interfere in any way with the right of the Company to change such
person’s compensation or other benefits or to terminate the employment of such person, with or without cause. 

  
 22 

 9.3. Restriction Against Assignment 

The Company shall pay all amounts payable hereunder only to the person or persons designated by this Plan and not to any other person or
corporation. No part of a Participant’s Accounts shall be liable for the debts, contracts, or engagements of any Participant, his or her Beneficiary, or successors in interest, nor shall a Participant’s Accounts be subject to execution by
levy, attachment, or garnishment or by any other legal or equitable proceeding, nor shall any such person have any right to alienate, anticipate, commute, pledge, encumber, or assign any benefits or payments hereunder in any manner whatsoever. If
any Participant, Beneficiary or successor in interest is adjudicated bankrupt or purports to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge any distribution or payment from this Plan, voluntarily or involuntarily, the
Committee, in its discretion, may cancel such distribution or payment (or any part thereof) to or for the benefit of such Participant, Beneficiary or successor in interest in such manner as the Committee shall direct. 

9.4. Withholding. 

The Company shall satisfy any state or federal income or other tax withholding obligation arising upon distribution of a Participant’s
Accounts. The Participant shall pay or provide for payment in cash of the amount of any taxes which the Company may be required to withhold with respect to the benefits hereunder. Without limiting the Company’s authority to satisfy the
withholding obligation from other sources, the Company may satisfy any withholding requirements with respect to the Plan by withholding wages, salary or bonus amounts otherwise payable to Participants. 

9.5. Amendment, Modification, Suspension or Termination. 

The Committee may amend, modify or suspend this Plan in whole or in part, except that (i) no amendment, modification or suspension shall
have any retroactive effect to reduce any 

  
 23 

 
amounts allocated to Participants’ Accounts, and (ii) Section 4.3 may not be amended, modified or suspended so as to, with respect to any amounts credited to the Accounts as of the
date of such amendment, reduce the amount of investment gains to be credited to Participants’ Accounts in accordance with Section 4.3. The Committee may terminate and liquidate this Plan and distribute all vested benefits hereunder in
accordance with the requirements of Treasury Regulation 1.409A-3(j)(4)(ix)(A), (B) or (C) promulgated under Code Section 409A (or any similar successor provision), which regulation generally provides that a deferred compensation
arrangement such as this Plan may be terminated within twelve (12) months following a dissolution or change in control of the Company or may be terminated if the Company also terminates all other similar deferred compensation arrangements and
distributes all benefits under this Plan not less than twelve (12) months and not more than twenty-four (24) months following such termination. The Committee may, in its discretion, accelerate the vesting of any or all Participants’
Accounts under this Plan in connection with any such Plan termination and liquidation. 
 9.6. Governing Law. 

Except to the extent preempted by ERISA or other applicable federal law, this Plan shall be construed, governed and administered in accordance
with the laws of the State of Delaware without regard to principles of conflict of laws. 
 9.7. Receipt or Release. 

Any payment to a Participant or the Participant’s Beneficiary in accordance with the provisions of this Plan shall, to the extent
thereof, be in full satisfaction of all claims against the Committee and the Company. The Committee may require such Participant or Beneficiary, as a condition precedent to such payment or delivery, to execute a receipt and release to such effect.

  
 24 

 9.8. Headings etc. Not Part of Agreement. 

Headings and subheadings in this Plan are inserted for convenience of reference only and are not to be considered in the construction of the
provisions hereof. 
 9.9. Code Section 409A. 

To the extent that this Plan is subject to Code Section 409A, this Plan shall be construed and interpreted to the maximum extent
reasonably possible to avoid the imputation of any tax, penalty or interest pursuant to Code Section 409A. If any portion of a Participant’s Account balance under this Plan is required to be included in income by the Participant prior to
receipt due to a failure of this Plan to comply with the requirements of Code Section 409A and related Treasury Regulations, the Committee may determine that such Participant shall receive a distribution from this Plan in an amount equal to the
lesser of (i) the portion of his or her Account balance required to be included in income as a result of the failure of this Plan to comply with the requirements of Code Section 409A and related Treasury Regulations, or (ii) the
Participant’s unpaid vested Account balance.

 Science Applications International Corporation Retirement Plan 

ARTICLE I 
 NAME,
EFFECTIVE DATE AND PURPOSES 
 1.1 Name and Effective Date. Effective September 27, 2013, this Plan is hereby adopted by the
Company for the benefit of its employees in connection with (1) the distribution of the stock of SAIC Gemini, Inc. to the stockholders of SAIC, Inc. on September 27, 2013 and the introduction of a Company Stock Fund to hold shares of SAIC
Gemini, Inc. distributed to the Trust hereunder, (2) the change of the name of SAIC, Inc. to Leidos Holdings, Inc. (“Leidos Holdings”) and the change of the name of Science Applications International Corporation to Leidos, Inc.
(“Leidos”), (3) the spin-off of Leidos Plan assets to this Plan and (4) the change of the name of the Science Applications International Retirement Plan to the Leidos Retirement Plan. 

This Plan was created when Leidos caused the accounts (including any outstanding loan balances) in the Leidos Plan attributable to Employees
who participate in this Plan as of September 27, 2013, and all of the assets in the Leidos Plan related thereto, to be transferred in-kind to this Plan, and effective as of the date of such transfer, the Company agrees to assume and to fully
perform, pay, and discharge, all obligations of the Leidos Plan relating to the accounts of this Plan’s Beneficiaries. It is intended that the transfer of assets shall be conducted in accordance with Section 414(l) of the Code, Treasury
Regulation Section 1.414(1)-1, and Section 208 of ERISA, and the Plan is to be regarded as a spin-off plan from the Leidos Plan. Because this Plan includes assets and accounts from the Leidos Plan, which itself is the result of the mergers
of historic plans sponsored or acquired by Leidos or a predecessor, the history of the Leidos Plan is recounted here, to the extent it pertains to the assets held in this Plan. 

Leidos (previously named Science Applications International Corporation) adopted the Science Applications International Corporation Profit
Sharing Retirement Plan on February 1, 1970 (the “PSRP”). Effective January 1, 1995, the PSRP was merged with the Science Applications International Corporation Profit Sharing Plan II, which was originally adopted as the SAIC
COMSYSTEMS Division Money Accumulation Pension Plan on February 1, 1977 and was subsequently merged with the TSC Profit Sharing Retirement Plan effective January 1, 1992. The PSRP was amended and restated in its entirety most recently
effective January 1, 2001 and has been amended subsequently in several respects. 
 Leidos adopted the Science Applications
International Corporation Cash or Deferred Arrangement (the “CODA”) effective January 1, 1983. The CODA was amended and restated in its entirety most recently effective as of January 1, 2001 and has been subsequently amended in
several respects. 

  
 1 

 Science Applications, Inc. established the Science Applications, Inc. Stock Bonus Retirement Plan
effective February 1, 1973 (the “Predecessor Plan”). In connection with the reorganization between Science Applications, Inc. and Leidos effected October 1, 1981, Leidos adopted the Predecessor Plan and the name of Predecessor
Plan was changed to the Science Applications International Corporation Stock Bonus Retirement Plan. The Predecessor Plan was amended and restated in its entirety effective as of January 1, 1985, and has been amended in several respects and has
undergone restatements and amendments subsequent to that date, most recently effective as of January 1, 2001. The resulting plan was known as the Science Applications International Corporation Employee Stock Retirement Plan (the
“ESRP”). 
 Effective as of November 28, 2003, the PSRP was merged with the CODA, and the merged plan was renamed the Science
Applications International Corporation 401(k) Profit Sharing Plan. In addition, effective as of January 1, 2006, (i) the ESRP was merged with and into the Leidos Plan, and (ii) an additional component (“ESOP Feature”) was
added to the Leidos Plan. In connection with such merger, the Plan was renamed the Science Applications International Corporation Retirement Plan and was restated in its entirety effective as of January 1, 2006, and again restated in its
entirety effective as of January 1, 2008. This Plan was amended and restated in its entirety effective as of January 1, 2010 except as may otherwise be provided herein. The Roth Deferral feature was effective April 1, 2008 or as soon
as administratively feasible thereafter. 
 The Plan reads as follows: 

1.2 Plan Purposes. This Plan is designed to foster and expand employee ownership of Company Stock through a tax-qualified profit sharing
plan for purposes of Sections 401(a) and 501(a) of the Code and provides a vehicle whereby Eligible Employees may save for retirement by electing to defer the receipt of some portion of their income and to have those amounts contributed to the Plan
under a “cash or deferred arrangement” within the meaning of Section 401(k) of the Code. In addition, the ESOP Feature of the Plan consists of both a stock bonus plan and an employee stock ownership plan intended to qualify under
Sections 401(a) and 4975(e)(7) of the Code, and is designed as such to invest primarily in Company Stock.

 ARTICLE III 

CONTRIBUTIONS 
 3.1
Elective Deferrals. 
 (a) Election to Defer. Subject to the limitations of this Article III and Article IV, each Participant may
elect to defer up to seventy-five percent (75%) of his Compensation on a pre-tax basis for a Plan Year, except that with respect to such portion of his Elective Deferrals that the Participant designates as Roth Deferrals, such contributions
shall be treated by the Company as includible in the Participant’s income at the time the Participant would have received that amount in cash if the Participant had not made an Elective Deferral election. The deferred amount shall be
contributed directly by the Company to the Trust Fund as Elective Deferrals and, if applicable, Catch-Up Contributions. For purposes of this Section 3.1, the Participant’s Compensation shall be determined prior to the reduction caused by
the deferral made pursuant to this Section 3.1. 
 An eligible Participant who has elected to participate in the Excess Plan for a Plan Year must make
his Elective Deferral election during the Plan Year immediately preceding the Plan Year in which such election is effective. 
 (b)
Termination of, Change in Rate of, or Resumption of Elective Deferrals. A Participant’s Elective Deferrals election shall remain in effect, notwithstanding any change in Compensation until the Participant elects to change the election. A
Participant may at any time submit a request to the Committee to terminate, alter the rate of, or resume his Elective Deferrals. An eligible Participant who has elected to participate in the Excess Plan for a Plan Year shall be permitted to change
his or her election of Elective Deferrals or Catch-Up Contributions effective as of the first day of such Plan Year, and shall not be permitted to change, discontinue, or resume his or her election of Elective Deferrals or (if applicable) Catch-Up
Contributions during that Plan Year; provided, however, that if such a Participant has a hardship withdrawal under Section 6.3 or has an unforeseeable emergency as defined in the Excess Plan, the Participant may elect, in a manner prescribed by
the Committee, to completely discontinue all Elective Deferrals and Catch-Up Contributions (if applicable) beyond the six (6) month suspension required under Section 6.3(b)(ii)(5). Such a Participant may not resume contributions to the
Plan for the remainder of the Plan Year. 
 (c) Contribution and Allocation of Elective Deferrals. The Company shall reduce the
Participant’s Compensation in the amount of the Participant’s Elective Deferrals and shall make a contribution to the Trustee equal to such reduction as soon as practicable after such amounts are withheld from the Participant’s
Compensation, but in any event within time prescribed under applicable regulations. Such contributions shall be allocated to Participants’ Plan Accounts, except to the extent that such contributions are designated as Roth Deferrals, in which
case such contributions shall be allocated to Participants’ Roth Deferral Accounts. 
 (d) 402(g) Limit on Elective Deferrals.

 (i) Elective Deferrals made on behalf of any Participant under this Plan and all other plans maintained by the Company or an Affiliated
Company shall not exceed the limitation under Section 402(g)(1) of the Code for the taxable year of the Participant, as adjusted annually under Section 402(g)(4) of the Code. 

  
 4 

 (ii) In the event that the dollar limitation provided for in subsection (d)(i) is exceeded, such
excess Elective Deferrals shall be treated, to the extent permissible, as Catch-Up Contributions pursuant to Section 414(v) of the Code. To the extent that the dollar limitation provided for in subsection (d)(i) is exceeded because the
Participant made elective deferrals to a cash or deferred arrangement maintained by an unrelated employer during the same taxable year, the Participant shall be required to request that any excess elective deferrals be refunded from the cash or
deferred arrangement maintained by the unrelated employer. 
 (e) Section 401(k) Limitations on Elective Deferrals. 

(i) The Committee may estimate at such times as the Committee in its discretion determines, the extent, if any, to which the deferral of
taxation on Elective Deferrals under Section 401(k) of the Code may not be available to any Participant or class of Participants. In accordance with any such estimate, the Committee may modify the limits in Section 3.1(a) or set initial or
interim limits for Elective Deferrals relating to any Participant or class of Participants. These rules may include provisions authorizing the suspension or reduction of Elective Deferrals above a specified dollar amount or percentage of
Compensation, or any other means adopted by the Committee. 
 (ii) For each Plan Year, an actual deferral percentage will be determined for
each Employee meeting the requirements of Section 2.1. The actual deferred percentage shall equal the ratio of the total amount of Elective Deferrals, Qualified Matching Contributions and Additional Company Contributions made on behalf of or
allocated to the Employee for the Plan Year divided by the Employee’s Compensation for the Plan Year. In the case of any Participant who is a Highly Compensated Employee and who is eligible to participate in one or more other defined
contribution plans of the Company or an Affiliated Company containing a cash or deferred arrangement described in Section 401(k) of the Code, the actual deferral percentage shall be determined by treating this Plan and all such other plans
(other than those which may not be aggregated under Treasury Regulations) as a single plan. With respect to Employees who have met the requirements of Section 2.1, and who have made no Elective Deferrals under the Plan, such actual deferral
percentage will be zero. 
 (iii) The average of the actual deferral percentages for Highly Compensated Employees in the Plan Year (the
“High Average”) when compared with the average of the actual deferral percentages for Non-Highly Compensated Employees in the applicable year (the “Low Average”) must meet one of the following requirements: 

(1) The High Average is no greater than 1.25 times the Low Average; or 

(2) The High Average is no greater than two times the Low Average, and the High Average is no greater than the Low Average plus two
percentage points. 

  
 5 

 (3) The “applicable year” under the prior year testing method is the Plan Year
immediately before the Plan Year being tested. The “applicable year” under the current year testing method is the Plan Year being tested. The Plan shall use the current year testing method for the 2013 testing year and subsequent years
unless and until changed by the Committee to the prior year method consistent with procedures prescribed by the Internal Revenue Service pursuant to Code Sections 401(k)(3)(A) and 401(m)(2)(A). 

(iv) If, at the end of the Plan Year, a Participant or class of Participants has excess Elective Deferrals, then the Committee may elect, at
its discretion, to pursue either of the following courses of action or any combination thereof: 
 (1) Excess Elective Deferrals, and any
earnings attributable thereto through the end of the Plan Year to which such excess Elective Deferrals relate (such earnings to be determined pursuant to applicable Treasury Regulations), may be distributed to Participant(s) no later than 12 months
following the close of the Plan Year to which the excess Elective Deferrals relate. Any such excess Elective Deferrals distributed from the Plan with respect to a Participant for a Plan Year shall be reduced by any amount previously distributed to
such Participant under Section 3.1(d) for the Participant’s taxable year ending with or within such Plan Year. The amount of any Participant’s excess Elective Deferrals is determined under subsection (e)(v). 

(2) The Company, in its discretion, may make an Additional Company Contribution to the Plan, which will be allocated as of a date within the
applicable year among the Accounts of Non-Highly Compensated Employees who have met the requirements of Section 2.1. Such contributions shall be considered ‘qualified non-elective contributions’ under applicable Treasury Regulations,
and shall not exceed the product of each affected Non-Highly Compensated Employee’s Compensation and the greater of 5% or two times the Plan’s ‘representative contribution rate’ as defined in Treasury Regulations
Section 1.401(k)-2(a)(6)(iv)(B). Alternatively, the Company, in its discretion, may make a Qualified Matching Contribution to the Plan, which will be allocated as of a date within the applicable year to Non-Highly Compensated Participants who
made Elective Deferrals. Such contributions shall be considered ‘qualified matching contributions’ under applicable Treasury Regulations. In either case, contributions made under this subparagraph (2) shall be fully (100%) vested
at all times and shall be subject to the withdrawal restrictions which are applicable to Elective Deferrals. 
 (v) Excess Elective
Deferrals shall be determined by the Committee in accordance with this Section 3.1(e)(v). The Committee shall calculate a tentative reduction amount to the Elective Deferrals of the Highly Compensated Employee(s) with the highest actual
deferral percentage equal to the amount which, if they were actually reduced, would enable the Plan to meet the limits in Section 3.1(e)(iii) or to cause the actual deferral percentage of such Highly Compensated Employee(s) to equal the actual
deferral percentage of the Highly Compensated Employee(s) with the next-highest actual deferral percentage. The process shall be repeated until the limits in Section 3.1(e)(iii) above are satisfied. The aggregate amount of the tentative
reduction amounts in the preceding sentence shall constitute “Refundable Contributions.” The entire aggregate amount of Refundable Contributions shall be refunded to Highly Compensated Employees. The amount to be refunded to each Highly
Compensated Employee (which shall constitute his excess Elective Deferrals) shall be determined as follows: 

  
 6 

 
(A) the Elective Deferrals of the Highly Compensated Employee(s) with the highest dollar amount of Elective Deferrals shall be refunded to the extent that there are Refundable Contributions or to
the extent necessary to cause the dollar amount of Elective Deferrals of such Highly Compensated Employee(s) to equal the dollar amount of Elective Deferrals of the Highly Compensated Employee(s) with the next-highest Elective Deferrals, and
(B) the process in the foregoing clause shall be repeated until the total amount of Elective Deferrals refunded equals the total amount of Refundable Contributions. The earnings attributable to excess Elective Deferrals will be determined in
accordance with Treasury Regulations. The Committee will not be liable to any Participant (or his Beneficiary, if applicable) for any losses caused by inaccurately estimating or calculating the amount of any Participant’s excess Elective
Deferrals and earnings attributable to Elective Deferrals. 
 (vi) In the event that the Committee determines that an amount to be deferred
pursuant to the election provided in Section 3.1 would cause the Company Contributions under this and any other tax qualified retirement plan maintained by the Company or any Affiliated Company to exceed the applicable deduction limitations
contained in Code Section 404, or to exceed the maximum Annual Addition determined in accordance with Article IV, the Committee may treat such amount in accordance with the rules set forth above in Section 3.1(e)(i) above. 

(vii) In the discretion of the Committee, the tests described in this Section may be applied by aggregating the Plan with any other defined
contribution plans permitted under the Code. For purposes of determining whether the Plan satisfies the requirements of this Section 3.1(e), all Elective Deferrals and elective contributions made under any other plan maintained by the Company
which is aggregated with the Plan for purposes of Section 401(a) or 410(b) of the Code (other than Section 410(b)(2)(A)(ii)) are to be treated as made under a single plan. Furthermore, if two or more plans are permissively aggregated for
purposes of the test described in this subsection (e), the aggregated plans must also satisfy Sections 401(a)(4) and 410(b) of the Code as though they were a single plan. If a Highly Compensated Employee participates in two or more cash or deferred
arrangements of the Company or any Affiliated Company with different plan years, then all such cash or deferred arrangements shall be aggregated and the actual deferral percentage for each such Highly Compensated Employee shall be determined by
taking into account all Elective Deferrals for the plan year being tested. 
 3.2 Voluntary Contributions. No Voluntary Contributions
are permitted under the Plan. Voluntary Contributions made under the Leidos Retirement Plan and transferred to this Plan shall be maintained in a Voluntary Account as set forth herein. 

3.3 Company Matching Contributions. 

(a) Amount of Company Matching Contributions. Subject to the limitations of this Section 3.3 and Article IV, for each Plan Year
the Company may, in its sole discretion, make a Company Matching Contribution. The amount, if any, of the Company Matching Contribution for each Fringe Rate Group shall be determined by the Company in its sole discretion. The amounts or percentages
of Company Matching Contributions among Fringe Rate Groups may differ or may be zero. However, in no event shall the amount of a Company 

  
 7 

 
Matching Contribution for any Plan Year result in the allocation to any Participant’s Account in excess of one hundred percent (100%) of that portion of such Participant’s Elective
Deferrals which do not exceed six percent (6%) of such Participant’s Match Eligible Compensation for the applicable Plan Year. Thus, with respect to a Participant, the Company Matching Contribution shall not exceed six percent (6%) of
such Participant’s Match Eligible Compensation. For avoidance of doubt, the Company shall not make Company Matching Contributions with respect to amounts treated as Catch-Up Contributions. 

(b) Contribution and Allocation of Company Matching Contributions. The Company shall pay to the Trustee the Company Matching
Contributions for any Plan Year no later than the due date for filing the federal income tax return (including extensions) of the Company for the taxable year with respect to which the contribution is made. The Company Matching Contributions with
respect to each Fringe Rate Group for any Plan Year shall be allocated to the Company Matching Account maintained for the Participant on behalf of whom the contribution under Section 3.3(a) was made. For avoidance of doubt, the Company Matching
Contribution for each Fringe Rate Group shall be separately allocated only to the Participants employed in the Fringe Rate Group for which such contribution was made. The Company may designate separate Fringe Rate Groups for purposes of determining
the amount of Company Matching Contributions to be allocated to Participants. In addition, the Company may designate that Company Matching Contributions shall be allocated with respect to Elective Deferrals made while a Participant is an Employee of
a designated Fringe Rate Group only if such Participant is employed by the Company or an Affiliated Company on the last working day of the Plan Year. 

(c) Section 401(m) Limitations on Company Matching Contributions. 

(i) The Committee may estimate, at such times as the Committee in its discretion determines, the extent, if any, to which Company Matching
Contributions may not be available to any Participant or class of Participants as a result of the limitations of Code Section 401(m). In accordance with any such estimate, the Committee may modify the percentages in Section 3.3(a) or set
initial or interim limits or percentages for Company Matching Contributions relating to any Participant or class of Participants. After determining the amount of excess Elective Deferrals, if any, under Section 3.1(e), the Committee shall
determine the aggregate contribution percentage under (ii) below. 
 (ii) For each Plan Year, a contribution percentage will be
determined for each Employee meeting the requirements of Section 2.1. The contribution percentage shall equal the ratio of the total amount of Company Matching Contributions made on behalf of or allocated to the Employee for the Plan Year
divided by the Employee’s Compensation for the Plan Year. In the case of any Participant who is a Highly Compensated Employee and who is eligible to participate in one or more other defined contribution plans of the Company or an Affiliated
Company to which Company Matching Contributions are made, the contribution percentage shall be determined by treating this Plan and such other plans (other than those which may not be aggregated under Treasury Regulations) as a single plan. With
respect to Employees who have met the requirements of Section 2.1 and for whom there were no Company Matching Contributions under the Plan, such contribution percentage will be zero. 

  
 8 

 (iii) The average of the contribution percentages for Highly Compensated Employees in the Plan
Year (the “High Average”) when compared with the average of the contribution percentages for Non-Highly Compensated Employees in the applicable Year (the “Low Average”) must meet one of the following requirements: 

(1) The High Average is no greater than 1.25 times the Low Average; or 

(2) The High Average is no greater than two times the Low Average, and the High Average is no greater than the Low Average plus two
percentage points. 
 (3) The “applicable year” under the prior year testing method is the Plan Year immediately before the Plan
Year being tested. The “applicable year” under the current year testing method is the Plan Year being tested. The Plan shall use the current year testing method for the 2013 testing year and subsequent years unless and until changed by the
Committee to the prior year method consistent with procedures prescribed by the Internal Revenue Service pursuant to Code Sections 401(k)(3)(A) and 401(m)(2)(A). 

(iv) If, at the end of the Plan Year, a Participant or class of Participants has excess contributions, then the Committee may elect, at its
discretion, to pursue any of the following courses of action or any combination thereof: 
 (1) Excess Company Matching Contributions (and
any earnings attributable thereto through the end of the Plan Year) attributable to excess Elective Deferrals may be forfeited. 
 (2)
Excess Company Matching Contributions (and any earnings attributable thereto through the end of the Plan Year) that are not vested may be forfeited. 

(3) Excess Company Matching Contributions (and any earnings attributable thereto through the end of the Plan Year to which such excess
Company Matching Contributions relate, such earnings to be determined under applicable Treasury Regulations) may be distributed to the Participant no later than 12 months after the close of the Plan Year. The Committee may distribute (or forfeit
pursuant to subsection (c)(iv)(1) above) Company Matching Contributions attributable to excess Elective Deferrals prior to distributing any other Company Matching Contributions. 

(4) Notwithstanding the foregoing, the conditions in this subsection (c)(iv)(4) must be met if there are Company Matching Contributions
allocated to a Participant which are attributable to excess Elective Deferrals. In such case, such Company Matching Contributions shall not be allocated to the Account of any Participant who had excess Company Matching Contributions in such Plan
Year. In addition, Company Matching Contributions remaining in the Plan allocated to the Participant after satisfying this Section 3.3(c) cannot exceed the amount which may be allocated under Section 3.1 when taking into account only those
Elective Deferrals remaining in the Plan after satisfying Section 3.1(d), 3.1(e) and this Section 3.3(c). Any such excess Company Matching Contributions (and earnings attributable thereto) must be forfeited or distributed pursuant to
subsections (c)(iv)(1), (c)(iv)(2) or (c)(iv)(3) immediately above. 

  
 9 

 (v) Excess Company Matching Contributions shall be determined by the Committee in accordance
with this Section 3.3(c)(v). The Committee shall calculate a tentative reduction amount to the Company Matching Contributions made with respect to the Highly Compensated Employee(s) with the highest contribution percentage equal to the amount
which, if they were actually reduced, would enable the Plan to meet the limits in Section 3.3(c)(iii) above or to cause the contribution percentage of such Highly Compensated Employee(s) to equal the actual contribution percentage of the Highly
Compensated Employee(s) with the next-highest actual contribution percentage. The process shall be repeated until the limits in Section 3.3(c)(iii) above are satisfied. The aggregate amount of the tentative reduction amounts in the preceding
sentence shall constitute “Refundable Matching Contributions.” The entire aggregate amount of Refundable Matching Contributions shall be refunded to Highly Compensated Employees. The amount to be refunded to each Highly Compensated
Employee (which shall constitute his excess Company Matching Contributions) shall be determined as follows: (A) the Company Matching Contributions made with respect to the Highly Compensated Employee(s) with the highest dollar amount of
aggregate Company Matching Contributions shall be refunded to the extent that there are Refundable Matching Contributions or to the extent necessary to cause the dollar amount of Company Matching Contributions of such Highly Compensated Employee(s)
to equal the dollar amount of Company Matching Contributions made with respect to the Highly Compensated Employee(s) with the next-highest aggregate Company Matching Contributions, and (B) the process in the foregoing clause shall be repeated
until the total amount of Company Matching Contributions refunded equals the total amount of Refundable Matching Contributions. The earnings attributable to excess Company Matching Contributions will be determined in accordance with Treasury
Regulations. The Committee will not be liable to any Participant (or his Beneficiary, if applicable) for any losses caused by inaccurately estimating or calculating the amount of any Participant’s excess Company Matching Contributions and
earnings attributable to such Company Matching Contributions. 
 (d) Forfeiture of Company Matching Contributions Attributable to Excess
Deferrals. Company Matching Contributions attributable to Elective Deferrals that exceed the limits of Section 3.1(d) or Section 3.1(e) shall be forfeited and allocated as set forth in Section 8.1. 

3.4 Profit Sharing, ESOP and Certain Additional Company Contributions. 

(a) For each Plan Year the Company may, in its sole discretion, contribute to the Trust Fund an amount or amounts to be determined by the
Board of Directors in its discretion as a Profit Sharing Contribution and/or an ESOP Contribution. The amount, if any, of the Profit Sharing Contribution and ESOP Contribution for each Fringe Rate Group, shall be determined by the Company in its
sole discretion. Such discretion may result in different amounts or percentages (including zero) of Profit Sharing Contributions and/or ESOP Contributions among Fringe Rate Groups. The Company’s Profit Sharing Contribution and ESOP Contribution
to the Trust Fund shall be made no later than the due date for filing the federal income tax return (including extensions) of the Company for the taxable year with respect to which the 

  
 10 

 
contribution is made. Any Profit Sharing Contributions and ESOP Contributions shall be subject to the requirements and restrictions of this Section 3.4 and subject also to the right of the
Company to amend or terminate this Plan or to suspend or discontinue Profit Sharing Contributions and ESOP Contributions to this Plan. 

(b) All Profit Sharing Contributions and ESOP Contributions to the Trust Fund shall be held on an unallocated basis until allocated, as
applicable, to Participants’ Profit Sharing Accounts and ESOP Accounts as provided under this Plan or otherwise used or applied in accordance with the provisions of this Plan. Pending such allocation, Profit Sharing Contributions and ESOP
Contributions shall be invested as directed, or under rules prescribed by the Committee. All gains or losses on such investments shall be allocated as provided in Section 8.3 and may be used for the payment of Plan expenses. 

(c) Profit Sharing Contributions and ESOP Contributions with respect to each Fringe Rate Group for any particular Plan Year (unadjusted for
income, gain and loss, which shall be allocated separately pursuant to Section 8.3) shall be separately allocated only to the Participants (A) employed in the Fringe Rate Group for which such contribution was made, (B) who completed
850 or more Hours of Service during the Plan Year and (C) who either are employed by the Company or an Affiliated Company on the last working day of the Plan Year or whose employment terminated during the Plan Year as a result of death,
retirement on or after the Normal Retirement Date, Disability or involuntary lay-off (other than for cause, as determined by the Committee in its sole discretion) (“Eligible Participants”). The Profit Sharing Contribution and ESOP
Contributions for each Fringe Rate Group shall be allocated, as applicable to the Profit Sharing Account or ESOP Account of each Eligible Participant in that Fringe Rate Group in the ratio that each such Eligible Participant’s total
Compensation for the Plan Year while a member of such Fringe Rate Group bears to all such Eligible Participants’ total Compensation for such Plan Year while members of such Fringe Rate Group. 

(d)(1) The Company may, in its sole discretion, contribute to the Trust Fund an Additional Company Contribution to be allocated solely to
certain Participants (as described in Section 3.4(d)(2)) who provide services on Company contracts that are subject to the McNamara-O’Hara Service Contract Act (the “SCA”). The amount or amounts of any such contribution shall be
determined by the Board of Directors in its discretion, or if applicable, by authorized officers of the Company as appropriate to satisfy contractual obligations with respect to such Participants. Any such Additional Company Contributions shall be
subject to the requirements and restrictions of this Section 3.4 and subject also to the right of the Company to amend or terminate this Plan or to suspend or discontinue such contributions to this Plan. 

(2) Additional Company Contributions with respect to Participants who provide services on Company contracts that are subject to the SCA shall
be separately allocated only to those Participants (A) for whom such contribution is made to satisfy an obligation under the SCA, and (B) who are Non-Highly Compensated Employees for the Plan Year for which such contribution is made
(“Eligible SCA QNEC Participants”). The Additional Company Contributions for a group of Eligible SCA QNEC Participants shall be allocated to the Plan Account of each such Eligible SCA QNEC Participant based upon the terms of the applicable
contract subject to the SCA. 

  
 11 

 3.5 Other Provisions Regarding Company Contributions. 

(a) Expenses. The Company may, in its discretion, make contributions at any time to defray Plans expenses as provided in
Section 8.3. 
 (b) Corrective Contributions. If an error has been made in calculating the amount of any required Company
Contributions or because of any other error there was a mistake which resulted in the Company contributing the incorrect amount of contributions for a particular Plan Year or Plan Years, the Company may adjust the amount of its contributions to the
extent necessary to correct its mistake. The Company may make these corrections prospectively or retrospectively in its discretion. 

3.6 Rollover Contributions and In-Plan Roth Conversions. 

(a) An Eligible Employee may transfer to the Trust Fund a Rollover Contribution pursuant to procedures approved by the Committee. The
Committee shall develop such procedures and may require such information as it deems necessary or desirable to determine that the proposed transfer will meet the requirements of a Rollover Contribution. Upon approval by the Committee, the amount
transferred shall be deposited in the Trust Fund and shall be credited to a Rollover Account. Such Account shall be one hundred percent (100%) vested in the Employee, shall be valued in accordance with Section 3.9, but shall not share in
allocation of Company Matching Contributions, Qualified Matching Contributions, forfeitures, Profit Sharing Contributions or ESOP Contributions. Upon termination of employment, the total amount of the Rollover Account shall be treated as part of the
Employee’s ‘Distributable Benefit’ under Section 6.5 and distributed in accordance with Sections 6.1 through 6.4, as applicable. For avoidance of doubt, a Rollover Contribution shall not include the portion of any distribution
that otherwise would not be includable in gross income. Notwithstanding the foregoing, the Plan may accept a Rollover Contribution to a Roth Deferral Account, provided that such Rollover Contribution is a ‘direct rollover’ (as defined in
Section 6.6) 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.

 (b) In-Plan Roth Conversions. 

(i) To the extent permitted under this Section 3.6(b), a Participant described in this Section 3.6(b) may elect that the eligible
portion of his or her Accounts be designated an In-Plan Roth Conversion to be maintained in the Participant’s In-Plan Roth Conversion Account. Any such election shall be irrevocable. The Committee may establish rules and procedures governing
elections under this Section 3.6(b), including but not limited to the frequency of elections, required forms and deadlines. Such Account shall be one hundred percent (100%) vested in the Participant, shall be valued in accordance with
Section 3.9, but shall not share in allocation of Company Matching Contributions, Qualified Matching Contributions, forfeitures, Profit Sharing Contributions or ESOP Contributions. Upon termination of employment, the total amount of the In Plan
Roth Conversion Account shall be treated as part of the Employee’s ‘Distributable Benefit’ under Section 6.5 and distributed in accordance with Sections 6.1 through 6.4, as applicable. 

  
 12 

 (ii) A Participant who has either (1) reached at least age 59-1/2 or (2) terminated
employment with the Company, may elect that any portion of the following Accounts be designated as an In-Plan Roth Conversion, but only to the extent vested in such Accounts: Plan Account, Matching Contribution Account, Rollover Account, Profit
Sharing Account, Voluntary Account, TRASOP Account, CODA Account and PSRP Profit Sharing Account. 
 (iii) A Participant who has not
reached at least age 59-1/2, but who has completed at least 5 years of participation in the Plan, may elect that any portion of the following Accounts be designated as an In-Plan Roth Conversion, but only to the extent vested in such Accounts:
Matching Contribution Account, Rollover Account, Profit Sharing Account, Voluntary Account, TRASOP Account and PSRP Profit Sharing Account. 

(iv) A Participant who has neither reached age 59-1/2 nor completed at least 5 years of participation in the Plan may elect that any portion
of his or her Rollover Account and Voluntary Account be designated as an In-Plan Roth Conversion. 
 (v) Spousal consent shall not be
required in the case of an election by a Participant to designate any portion of his or her Survivor Annuity Subaccount as an In-Plan Roth Conversion, but the amount so converted shall remain subject to the rules set forth in Sections 401(a)(11) and
417 of the Code and Section 6.4 of the Plan applicable to Survivor Annuity Subaccounts. 
 3.7 Plan-to-Plan Transfers. 

(a) In its sole discretion, the Committee may authorize the Plan to accept a transfer, from a plan qualified under Code Section 401(a),
of a Participant’s account balance under such transferee plan. Any such transfer shall be allocated to a specified Account of the Participant as determined by the Committee. Information concerning certain such transfers are set forth in
appendices to this Plan which are incorporated herein. 
 (b) To the extent required by Code Section 411(d)(6), an Account balance
transferred pursuant to this Section 3.7 shall retain optional forms of benefit payments that were applicable to such Account balance prior to the transfer to the Plan. 

3.8 Investment of Accounts. 

(a) Investment Direction by Participants. 

(i) All contributions to the Plan (whether Company Contributions, Voluntary Contributions, Rollover Contributions or plan-to-plan transfers)
shall be invested as provided in this Section 3.8. Except as otherwise set forth in the Plan, the Committee shall establish rules setting forth the extent to which Participants may determine the manner in which their Accounts may be invested.
Consistent with such rules, the Committee shall establish a choice of at least three investment alternatives from which each Participant may select in determining the manner in which the applicable portions of his Plan Account, Roth Deferral Account
(if any), Profit Sharing Account (if any), Voluntary Contributions (if any), Matching Contribution Account (if any) and Rollover Account (if any) will be invested. The Committee shall prescribe procedures for investment of amounts allocated to an
Alternate Payee Account. 

  
 13 

 (1) To the extent permitted herein, a Participant may direct that Company Contributions be
invested all or in part in a Company Stock Fund within the Trust. No fiduciary (including but not limited to the Committee and the Trustees) shall have the authority or duty (x) to cause any Company Stock to be invested other than in Company
Stock (except for cash held pending distribution to Participants, Beneficiaries, or Alternate Payees and to facilitate Participant-directed changes to investment alternatives) or (y) to remove the Company Stock Fund as an investment alternative
under the Plan. 
 (2) The Committee may maintain separate subaccounts for the Company Stock Fund, including but not limited to the Closed
Stock Subaccount and the Common Stock Subaccount. 
 (3) Transfers into the Closed Stock Subaccount shall not be permitted, and no
contributions or rollovers shall be made or allocated to the Closed Stock Subaccount. Any transfers, contributions and Rollovers to the Company Stock Fund shall be made to the Common Stock Subaccount. 

(4) All amounts held in the Company Stock Fund shall be subject to elections by Participants to transfer to another investment fund under the
Plan. 
 (ii) The Plan is designed to provide benefits largely through the long-term investment of Participant Accounts. It is not designed
to serve as a vehicle for speculative investment, such as short-swing securities trades. Plan fiduciaries shall execute Participant-directed investment transactions, fund transfers, distributions and related transactions within a reasonable period
of time after receiving proper instructions to do so, but neither the Plan nor Plan fiduciaries guarantee how promptly execution will commence or be completed. 

(iii) If the investment alternatives described above are established under the Plan, each Participant may elect to invest the assets of his
Accounts in such alternatives at such time, in such manner, and subject to such restrictions as the Committee shall specify. No more than 50% of a Participant’s Elective Deferrals and Rollover Contributions may initially be invested in the
Company Stock Fund. 
 (iv) Separate funds within the Trust Fund shall be established to reflect the available alternatives, and separate
subaccounts shall be established for each investment alternative selected by a Participant, and each such subaccount shall be valued separately. 

(v) The Committee, in its discretion, may permit Participants to transfer amounts from one investment alternative to one or more other
investment alternatives. An election to transfer such amounts shall be made only at such time, in such manner, and subject to such restrictions as the Committee may specify. The Committee may provide that future contributions may be invested in a
different investment alternative than amounts already accumulated in the Participant’s Account(s). 
 (vi) The Committee shall
prescribe rules relating to the investment of the assets in the Accounts of a Participant who fails to make an effective election, for any reason whatsoever, as to how all or a portion of his Accounts shall be invested. Without limitation, such
rules may provide for a “qualified default investment alternative,” as provided in Department of Labor Regulations under Section 404(c) of ERISA. 

  
 14 

 (vii) The Committee shall arrange for reports to be delivered or made available to Participants
regarding the investment of their funds pursuant to their investment elections. Failure of a Participant to notify the Committee regarding implementation of his investment election (or change therein) within thirty (30) days following any such
notice shall be deemed to be an election to have the Accounts invested in the manner shown on such report, even if the manner of investment is different from that specified in the Participant’s election form or investment instructions. If a
Participant has not received a notice confirming his investment election (or change therein) and does not notify the Committee or its designated delegate within thirty (30) days of the date such election (or change) was to be effective, the
Participant shall be deemed to have elected to have the Accounts invested in the manner in which they are in fact invested, even if that method differs from the Participant’s election form or investment instructions. 

(b) Investment of Accounts of Participants Subject to Governmental Conflict of Interest Rules. 

(i) If a Participant, by virtue of his spouse’s employment with the government or otherwise, is subject to governmental conflict of
interest rules that would, in the opinion of the General Counsel of the Company, require the Participant to divest himself of ownership of Company Stock, then, notwithstanding other Plan provisions, no portion of a Participant’s Accounts may be
invested in a Company Stock Fund and Company Contributions which would otherwise be directed to a Company Stock Fund within the Trust shall instead be invested from among the other Plan investment alternatives selected by the Participant. 

(ii) The Committee may prescribe such procedures and rules as may be required or desirable to implement this Section 3.8(b). 

(c) Leidos Stock Fund. 
 (i)
In General. Effective on the Effective Date, a new investment fund under the Plan shall be established which shall be called the Leidos Stock Fund. The establishment, maintenance and elimination of the Leidos Stock Fund shall be determined by
the Company and the Board of Directors or its authorized delegee, exercising its prerogative as plan settlor, and neither the Committee nor any other fiduciary of the Plan shall have any discretion with regard to the establishment, continued
inclusion or elimination of the Leidos Stock Fund, as required by the terms of the Plan. The Leidos Stock Fund shall be invested in Leidos Stock as well as cash and cash equivalents as determined by the Committee in its discretion. The Leidos Stock
Fund shall have established within it a Common Stock Subaccount and a Closed Stock Subaccount. 
 (ii) Subaccounts. Shares of Leidos
Stock formerly held in the common stock subaccount of the company stock fund in the Leidos Plan shall be allocated to the Common Stock Subaccount of the Leidos Stock Fund of this Plan, and shares of Leidos Stock formerly held in the closed stock
subaccount of the company stock fund of the Leidos Plan shall be allocated to the Closed Stock Subaccount of the Leidos Stock Fund of this Plan. 

  
 15 

 (iii) Investment Limitations. Following the Effective Date, no additional amounts may be
allocated to the Leidos Stock Fund, and any amounts transferred from the Leidos Stock Fund may not be returned to the Leidos Stock Fund at any time. 

(iv) Fund Transfers. Subject to the limitations of subparagraph (vi), below, a Participant may transfer amounts held in the Common
Stock Subaccount of the Leidos Stock Fund to the Common Stock Subaccount of the Company Stock Fund and amounts held in the Closed Stock Subaccount of the Leidos Stock Fund to the Closed Stock Subaccount of the Company Stock Fund. A Participant may
transfer amounts held in the Leidos Stock Fund to an investment alternative other than the Company Stock Fund at any time. 
 (v)
Dividends. All cash dividends on Leidos Stock allocated to Participants’, Beneficiaries’ and Alternate Payees’ Accounts may, as determined by the Company consistent with Section 404(k) of the Code, be retained in the
Participants’, Beneficiaries’ and Alternate Payees’ Accounts, or be paid out to the Participant, Beneficiary or Alternate Payee. Such retained dividends shall be invested on behalf of the Participant in the Company Stock Fund. 

(vi) Elimination of Leidos Stock Fund. The Leidos Stock Fund shall be discontinued on December 31, 2014. Participant-directed transfers
out of the Leidos Stock Fund may be made in accordance with applicable procedures at any time up to the deadline established by the Committee for effecting the necessary transactions consistent with the above. Any amounts remaining in the Leidos
Stock Fund after the deadline for such Participant-directed transfers shall be reallocated to a default investment alternative selected by the Committee. Assets in the Leidos Stock Fund may be transferred into the Company Stock Fund during the
period from the Effective Date through such deadline, or reallocated to the Company Stock Fund upon expiration of such deadline, whether or not the amount of the Participant’s Account invested in the Company Stock Fund at the time of such
transfer exceeds the 50% limit of Section 3.8(a)(iii) or will exceed such 50% limit as a result of such transfer. 
 3.9 Valuation
of Accounts. 
 (a) The Trustee shall value the assets of the Trust on the basis of fair market values as of each Valuation Date. 

(b) The Committee shall value the Accounts of each Participant, Suspended Participant and Alternate Payee as of the applicable Valuation Date
so as to reflect the current fair market value of each Account as of such Valuation Date. The valuation provisions of this Section 3.9 shall be applied and implemented in accordance with the rules established by the Committee. The Company, the
Committee and Trustee do not in any manner or to any extent whatsoever warrant, guarantee or represent that the value of a Participant’s Account shall at any time equal or exceed the amount previously contributed thereto, or that any valuation
or accounting method or practice will continue to be applied. 

  
 16 

 (c) If any Company Stock consists of securities listed on a national securities exchange, fair
market value of such Company Stock shall be considered to be equal to the closing price of such Company Stock (as reported in the consolidated transaction reporting system, or if not so reported, as reported on the principal exchange market for such
Company Stock by such exchange or on any system sponsored by such exchange) on the applicable Valuation Date. If any Company Stock consists of securities traded on a regular basis, as determined by the Company, in the over the counter market, the
fair market value of such Company Stock shall be considered to be equal to the average between the high bid price and the low asked price quoted by the automatic quotation system of a securities association registered under the federal securities
laws for the applicable Valuation Date. If any Company Stock is not readily tradable on an established securities market, then the fair market value of such Company Stock shall be determined by an independent appraiser meeting the requirements of
Code Section 401(a)(28)(C). Any valuation by an independent appraiser shall be made in good faith on at least an annual basis and shall be based on all relevant factors for determining the fair market value of securities. In the case of a
transaction involving Company Stock between the Plan and a ‘disqualified person,’ as defined in Code Section 4975(e)(2), the value of Company Stock involved in the transaction shall be determined as of the date of the transaction, and
the transaction shall otherwise meet the requirements of Section 7.6. 
 (d) Any Company Stock or Leidos Stock received by the Trustee
as a stock split, dividend, or as a result of a reorganization or other recapitalization of the Company shall be allocated as of the day on which the stock is received by the Trustee in the same manner as the Company Stock to which it is
attributable is then allocated. 
 (e) Allocation of Cash Dividends and Other Distributions Received in the Trust Fund. 

(i) All cash dividends paid to the Trustee with respect to Company Stock that has been allocated to an Account (if any) as of the date the
dividend is received by the Trustee shall be allocated to such Account. If the Company Stock in the Trust Fund is held in a Company Stock Fund as an investment alternative pursuant to Section 3.9, such that Participants have an interest in such
Company Stock only indirectly through an interest in such fund held in a subaccount, the cash dividends shall be allocated to such fund and shall thereafter be invested in accordance with the investment practices of such fund, and shall not be
allocated directly to a Participant’s Account or subaccount. Notwithstanding the foregoing, as determined by the Committee, cash dividends may be held in a short-term investment pending a determination regarding the extent to which the
dividends will be distributed pursuant to Section 12.3. 
 (ii) All cash dividends paid to the Trustee with respect to unallocated
Company Stock shall be allocated as provided in Section 8.3. 
 (iii) Other distributions received by the Trustee with respect to
investments of the Trust shall be allocated to the applicable fund(s) established pursuant to Section 3.8.

 ARTICLE IV 

LIMITATION ON ANNUAL ADDITIONS 

4.1 Definitions. 
 For
purposes of this Article IV, the following terms shall have the following meanings: 
 “Defined Contribution Plan” means a
plan described in Code Sections 414(i). 
 “Section 415 Compensation” shall mean a Participant’s wages within the
meaning of Code Section 3401(a) and all other payments of compensation to the Participant by the Company (in the course of the Company’s business) for which the Company is required to provide the Participant a written statement under Code
Sections 6041(d), 6051(a)(3) and 6052. Section 415 Compensation shall be determined without regard to any rules under Code Section 3401(a) that limit the remuneration included in wages based on the nature or location of the employment or
the services performed. Compensation for any limitation year is the compensation actually paid or includible in gross income during such year. Effective January 1, 1998, “Section 415 Compensation” shall include elective deferrals as
defined in Code Section 402(g)(3) of the Code and any amount which is contributed or deferred by the Company or an Affiliated Company at the election of an Employee and which is not includible in the gross income of the Employee by reason of
Code Sections 125, 132(f)(4) or 457. 
 4.2 Section 415 Limitation. 

Notwithstanding anything else contained herein, the Annual Additions to all Accounts of a Participant shall not exceed the lesser of $40,000
($45,000 as adjusted through 2007 and thereafter adjusted as permitted under Section 415(d)(1) of the Code and regulations issued thereunder) or 100% of the Participant’s Section 415 Compensation from the Company and all Affiliated
Companies during the Plan Year. 
 4.3 Annual Addition Limitations. 

(a) The compensation limitation of Section 4.2 of the Plan shall not apply to any contribution for medical benefits (within the meaning
of Code Section 419A(f)(2)) after separation from service which is treated as an Annual Addition. 
 (b) If any Company or any
Affiliated Company contributes amounts, on behalf of Participants covered by the Plan, to other Defined Contribution Plans, the limitation on Annual Additions provided in this Article IV shall be applied to Annual Additions in the aggregate to the
Plan and such other Defined Contribution Plans. Reduction of Annual Additions, where required, shall be accomplished by first refunding any voluntary contributions to Participants, then by reducing contributions under other Defined Contribution
Plans and this Plan in the following order: 
 (i) Earnings on unallocated Company contributions under such other Defined Contribution
Plans; 

  
 18 

 (ii) Earnings on unallocated Profit Sharing Contribution and ESOP Contribution under this Plan;

 (iii) Forfeitures under such other Defined Contribution Plans; 

(iv) Return of Elective Deferrals and reduction of corresponding Company Matching Contributions; 

(v) Company contributions under such other Defined Contribution Plans; and 

(vi) Profit Sharing Contributions and ESOP Contributions under this Plan. 

(c) In the event the limitations of Section 4.2 or this Section 4.3 of the Plan are exceeded, any excess shall be corrected in
accordance with the principles and/or procedures of the Employee Plans Compliance Resolution System described in IRS Revenue Procedure 2013-12, 2013-4 I.R.B. 313 (January 22, 2013) (or any corresponding successor guidance). 

To the extent allocations to a Participant are reduced under subsections (b)(i)-(vi) above, such reduced amounts shall be allocated and
reallocated to other Participants in the applicable Plan, except that Elective Deferrals shall be returned to the Participant. 
 4.4 No
Contractual Right to Excess Contributions. 
 If, in order to comply with the limitations of this Article IV, it becomes necessary to
reduce a Participant’s Account(s), to reduce or reallocate amounts previously allocated to such Accounts, or otherwise, such action(s) may be taken by the Committee and Trustee free of any contractual obligation to the Participant (or
Beneficiary) affected based on prior Account balances or allocations. 

  
 19 

 ARTICLE V 

VESTING 
 5.1 Fully
Vested Accounts. 
 A Participant’s Plan Account, Roth Deferral Account, Voluntary Account, Rollover Account, TRASOP Account, CODA
Account and Survivor Annuity Subaccount, if any, shall be 100% vested and nonforfeitable. 
 5.2 Employer Matching Contributions, Profit
Sharing Account and ESOP Account. 
 (a) Subject to the provisions of Section 5.2(b), the Vested Interest of each Participant or
Suspended Participant shall be equal to the amount determined by multiplying the balance in his Matching Contribution Account, Profit Sharing Account and ESOP Account on the applicable date by the Vested Interest determined in accordance with the
rules of Section 5.2(b) and the following schedule: 
  

						
	 Years of Service
	  	Vested Interest
	 Less than one year
	  	 	 	0	%
	 One year but less than two years
	  	 	 	20	%
	 Two years but less than three years
	  	 	 	40	%
	 Three years but less than four years
	  	 	 	60	%
	 Four years but less than five years
	  	 	 	80	%
	 Five years or more
	  	 	 	100	%

 A Participant’s PSRP Profit Sharing Account, if any, shall be fully vested. 

(b) The determination of a Participant’s or Suspended Participant’s Vested Interest in his Matching Contribution Account, Profit
Sharing Account and ESOP Account shall be subject to the following special rules: 
 (i) During an Employee’s period of employment
with the Company or an Affiliated Company (including periods while on an approved leave of absence, a Maternity or Paternity Absence, or while performing ‘qualified military service’ as defined in Section 414(u) of the Code), in the
event of his death, Disability, attainment of Normal Retirement Date, or a judicial declaration of his mental incompetence, the Employee’s Vested Interest shall become one hundred percent (100%), regardless of his number of Years of Service.

 (ii) Forfeitures shall be determined as follows: 

(1) A Participant who terminates employment prior to becoming one hundred percent (100%) vested in his Matching Contribution Account,
Profit Sharing Account and ESOP Account shall immediately forfeit the non-vested portion of such Accounts upon receiving a distribution in accordance with Section 6.1. 

  
 20 

 (2) In the case of a Participant with no Vested Interest in his Matching Contribution Account,
Profit Sharing Account and ESOP Account, the Participant shall be deemed to have received a distribution of zero dollars in respect of his Matching Contribution Account, Profit Sharing Account and/or ESOP Account, as applicable, and the forfeiture
shall occur within 120 days after his termination of employment. 
 (3) In the case of a Participant with a Vested Interest in his Matching
Contribution Account, Profit Sharing Account and ESOP Account, but who terminates employment prior to becoming one hundred percent (100%) vested in such Accounts and incurs five consecutive Breaks in Service prior to receiving a distribution
under Section 6.1, such Participant shall forfeit the non-vested portion of such Accounts within 120 days after the completion of the fifth consecutive Break in Service. 

(iii) A former Employee who is reemployed by the Company or an Affiliated Company, prior to incurring five consecutive Breaks in Service
shall be subject to Section 5.2(c). If a former Employee incurs five consecutive Breaks in Service prior to reemployment, amounts forfeited from his Matching Contribution Account, Profit Sharing Account and ESOP Account shall remain forfeited
and shall not be restored, and his Years of Service prior to such period of five consecutive Breaks in Service shall (subject to Section 5.2(c)) count only towards his Vested Interest applicable to allocations to his Matching Contribution
Account credited after such period of five consecutive Breaks in Service. 
 (iv) If an Employee whose Vested Interest is zero (and who has
no balance in a Survivor Annuity Subaccount, Plan Account, Roth Deferral Account, Voluntary Account, Rollover Account, TRASOP Account or CODA Account) upon his initial Break in Service incurs five or more consecutive Breaks in Service, his Years of
Service accumulated before the commencement of any such period of consecutive Breaks in Service shall not be taken into account for purposes of determining the Vested Interest in his Matching Contribution Account, his Profit Sharing Account and his
ESOP Account at any time or for any purpose. An Employee’s aggregate Years of Service shall not include any Years of Service not required to be taken into account under this Section 5.2(b) by reason of any Prior Break in Service. 

(v) No Employee shall be credited with any Years of Service performed for the Company, Leidos, an affiliate or a predecessor prior to
February 1, 1976, if the period of service would have been disregarded under the provisions of the Predecessor Plan in existence on the relevant date relating to continuity and interruptions of service and these rules requiring full-time
service as a condition for participation in the Predecessor Plan. 
 (vi) Prior to January 1, 2006, no Employee shall be given credit
for any Years of Service performed for the Company, Leidos, an affiliate or a predecessor before the computation period (as determined in accordance with the definition of “Compensation” in Section 13.1) during which the Employee
attained the age of 18. Individuals who were Employees of Leidos or an affiliate as of January 1, 2006 shall receive credit for any Years of Service performed before the computation period during which the Employee attained the age of 18;
individuals who were not Employees as of such date shall not receive such credit. Furthermore, no amounts forfeited as a result of a termination of employment prior to January 1, 2006 shall be restored as a result of the crediting of Years of
Service under this clause. 

  
 21 

 (vii) In the event of a divestiture of an operating group, business unit or division, the
Compensation Committee or the Compensation Committee’s designee may, in their sole discretion, determine, with respect to Eligible Employees whose employment with the Company terminates as a result of such divestiture and in lieu of the
otherwise applicable determination of Vested Interest specified in this Article V, (1) treat the Eligible Employees’ Vested Interest as 100%, notwithstanding their Years of Service prior to termination; or (2) treat such Eligible
Employees as Suspended Participants but credit Years of Service with the new employer to whom such group is divested for purposes of determining such Eligible Employees’ Vested Interest. Any such determination for a particular group, business
unit or division shall not bind the Company in any way with respect to any subsequent determination relating to a different group, business unit or division. In the event of a subsequent divestiture from the new employer, the Compensation Committee
or the Compensation Committee designee may make a similar determination regarding vesting acceleration. 
 (viii) In the event the Plan is
amended to change any vesting schedule under the Plan, each Participant having no less than three Years of Service shall be permitted to elect, within a reasonable period after the adoption of such amendment, to have his Vested Interest determined
under the Plan without regard to such amendment. 
 (ix) With respect to a Participant who was an employee of Leidos, an affiliate or a
predecessor as of December 31, 1994, the Vested Interest of the Participant in his Matching Contribution Account shall be 100%. Further, any Participant who was first employed before January 1, 1995 and is actively employed on
November 28, 2003 shall become 100% vested his Profit Sharing Account and ESRP Plan Account on November 28, 2003. A Participant who was first employed by Leidos, an affiliated company or a predecessor thereof before January 1, 1995
and terminated employment with Leidos, an affiliated company or a predecessor prior to November 28, 2003 shall become 100% vested in his Profit Sharing Account and ESRP Plan Account if he subsequently returns to active employment with the
Company, Leidos or an affiliate thereof on or after November 28, 2003. 
 (x) In order to comply with a government contract, or for
other business reasons, the Chief Executive Officer, President, Chief Operating Officer, or Executive Vice President for Human Resources of the Company (or a delegate of any such officer) may determine (without any requirement of action by the Board
of Directors), with respect to a designated category of Eligible Employees within a group or classification within the Company, including, without limitation, a group of newly Eligible Employees acquired through an acquisition, and in lieu of the
otherwise applicable determination of such Employees’ Vested Interest specified in this Article V, (1) to treat the Eligible Employees’ Vested Interest as 100%, notwithstanding their Years of Service; (2) to credit service
performed for the acquired company prior to the acquisition as Years of Service hereunder; or (3) to apply a more liberal vesting schedule than the schedule described in Section 5.2(a) for purposes of determining such Eligible
Employees’ Vested Interest. An Eligible Employee must satisfy any specified conditions (including but not limited to a requirement to execute a Mutual Agreement to Arbitrate Claims or similar agreement) in order to have his or her Vested
Interest determined under the preceding sentence. The designation of any such group or classification and the effective date of the method of determining the Vested Interest shall be made in writing and attached hereto as an exhibit and incorporated
herein. Any such determination for a particular group shall not bind the Company in any way with respect to any subsequent determination relating to a different group. 

  
 22 

 (xi) Notwithstanding anything to the contrary in this Section 5.2, a Participant who was
first employed by Leidos or an affiliated company before January 1, 1995, terminated employment with Leidos or an affiliated company prior to November 28, 2003 and whose Vested Interest in his Profit Sharing Account or ESRP Plan Account
was less than 100% on the date of his termination shall forfeit the nonvested portion of his Profit Sharing Account and ESRP Plan Account effective as of November 28, 2003 even if such former Employee has not received a distribution in
accordance with Article VI of the Plan. Any such forfeited amount shall be restored to the Participant’s Profit Sharing Account and ESRP Plan Account or ESOP Account by the Company from existing forfeitures if the Participant is reemployed by
the Company or an Affiliated Company and such restored amount shall become 100% vested in his Profit Sharing Account and ESRP Plan Account or ESOP Account as of his reemployment date. 

(c) If a Participant who was partially vested under Section 5.2(a) is reemployed by the Company or an Affiliated Company on (or before)
the Anniversary Date of the Plan Year in which his fifth consecutive Break in Service occurs, the Participant shall be entitled to have his Matching Contribution Account, Profit Sharing Account and ESOP Account reinstated by making the repayment
described in Section 8.2. 
 5.3 Alternate Payee Accounts. 

In the event that an Alternate Payee is awarded an interest in either the Matching Contribution Account, the Profit Sharing Account or the
ESOP Account of a Participant whose Vested Interest in such Account is less than 100%, to the extent expressly required under the terms of the applicable qualified domestic relations order, the Vested Interest of the Alternate Payee at any
subsequent time in that portion of the Alternate Payee Account attributable to such awarded interest shall be the same percentage as the Participant’s Vested Interest in his applicable Matching Contribution Account, Profit Sharing Account or
ESOP Account at that time, determined in accordance with Sections 5.1 and 5.2. 

  
 23 

 ARTICLE VI 

DISTRIBUTIONS 
 6.1
Distribution Upon Termination of Employment. The following rules shall apply in the case of a Participant whose employment with the Company terminates other than due to his death or Disability: 

(a) A Participant’s Distributable Benefit shall become distributable upon the Participant’s termination of employment with the
Company other than due to his death or Disability. 
 (b) The Participant’s Accounts shall continue to be valued pursuant to
Section 3.9, but no further allocations of Company Contributions under Article III shall be made to such Accounts, except for an allocation of Company Contributions representing Elective Deferrals made prior to the Participant’s
termination of employment and Company Matching Contributions related thereto. Notwithstanding the foregoing, an Eligible Participant (as defined in Section 3.4(c)) shall receive a Profit Sharing Contribution and an ESOP Contribution. 

(c) If a Participant’s Distributable Benefit exceeds $5,000, distribution shall be made upon the Participant’s termination of
employment only if the Participant so requests or consents to such distribution in writing. An explanation of the Participant’s right to defer distribution of his Distributable Benefit shall be provided to the Participant no less than 30 and no
more than 180 days before such distribution is to be made (consistent with such regulations as the Secretary of the Treasury may prescribe). If the Distributable Benefit of a terminating Participant is a distribution to which Code Sections
401(a)(11) and 417 do not apply, such distribution may commence less than 30 days after the notice described in the preceding sentence is given, provided that: (1) the Committee clearly informs the Participant that the Participant has the right
to a period of at least 30 days after receiving the notice to consider the decision of whether or not to elect a distribution, and (2) the Participant, after receiving the notice, affirmatively elects an immediate distribution. If a Participant
does not request an immediate distribution of his Distributable Benefit upon a termination of employment, (unless Treasury Regulations otherwise provide and the Committee adopts different rules), a Participant’s Distributable Benefit shall be
distributed to him as soon as administratively practicable following the latest of: 
 (i) the Participant’s termination of
employment, 
 (ii) the earlier of the date the Participant consents in writing to such distribution or attains age 62, or 

(iii) the date elected by the Participant, which shall not be later than the Required Payment Commencement Date. 

(iv) Distribution to a Participant upon the Participant’s Required Payment Commencement Date may, for any calendar year, if elected by
the Participant, be the minimum required distribution under Code Section 401(a)(9) and the regulations thereunder, as set forth in Section 6.5(i). A Participant making such an election may thereafter elect to receive any remaining amounts
in his Accounts in a single sum. 

  
 24 

 (d) Distributions shall be in the form of a cash lump sum, provided that a Participant may elect
to receive the portion of his Distributable Benefit invested in a Company Stock Fund in the form of shares of Company Stock (plus cash for any fractional shares), or in the form of cash. The value of the amount distributed in the form of cash from
the portion of a Participant’s Distributable Benefit invested in a Company Stock Fund shall be the net proceeds at the sale of the Company Stock liquidated pending distribution, plus cash for any fractional share. 

(e) In lieu of receiving his entire Distributable Benefit in a single lump-sum distribution as provided in Section 6.1(d), a Participant
may elect to receive a distribution of that portion of his Account(s) that is not invested in a Company Stock Fund within the Trust, while leaving in the Plan the remaining portion which is invested in a Company Stock Fund until a later distribution
date specified by the Participant, which in no event shall be a date after the Required Payment Commencement Date. Any such partial withdrawal shall be subject to such limitations and restrictions as may be imposed by Committee rule. Notwithstanding
the foregoing, with respect to any portion of the Participant’s Account attributable to Leidos Stock acquired by the ESRP after December 31, 1986 (as determined under terms of the ESRP and applicable Treasury Regulations), the Participant
may elect to have payment made in substantially equal annual payments over a period of five years, with the first such annual payment made not later than one year after the close of the Plan Year which is the fifth Plan Year following the Plan Year
in which the Participant separated from service with the Company. Notwithstanding the foregoing, a Participant who elects such a Leidos Stock Distributable Benefit may, at any time, request that the Committee pay him the Vested Interest in his
Accounts in a cash lump sum and, in such event, the distribution shall be made not later than one hundred twenty (120) days (or as soon thereafter as is reasonable for administrative purposes) after the close of the Plan Year in which such
request is made. A Participant (regardless of age) may elect to receive up to two distributions in the form of cash (not to include distribution in the form of shares of Company Stock) in any Plan Year of all or any portion of his or her Accounts.

 6.2 Designation of Beneficiary; Distribution Upon Death or Disability. 

(a) On a form prescribed by and delivered to the Committee, each Participant shall have the right to designate in writing a Beneficiary or
Beneficiaries whom such Participant desires to receive the benefits of this Plan in the event of such Participant’s death. A Participant’s designation of Beneficiary must be made directly with the Plan’s outside recordkeeper in a form
prescribed by the Committee. If a Participant fails to designate a Beneficiary as provided in the preceding sentence, the Participant shall be treated as not having made a Beneficiary designation until such time as the Participant makes a
designation in the approved format. 
 (b) A Participant may from time to time change his designated Beneficiary or Beneficiaries without
the consent of such Beneficiary or Beneficiaries by filing a new designation in the manner set forth herein. 

  
 25 

 (c) If a deceased Participant shall have failed to designate a Beneficiary, if the Committee
shall be unable to locate a designated Beneficiary after reasonable efforts have been made, if for any reason the designation shall be legally ineffective, or if the Beneficiary shall have predeceased the Participant (and no legally effective
contingent Beneficiary shall have been named), any distribution required to be made under the provisions of this Plan shall be payable to the Participant’s surviving spouse, and if the Participant had no surviving spouse, to the
Participant’s estate, and the surviving spouse or estate shall be considered the Beneficiary under this Plan. 
 (d) In the event that
a Participant shall predecease his Beneficiary and on the subsequent death of the Beneficiary a remaining distribution is payable under the applicable provisions of this Plan, the distribution shall be payable to the Beneficiary’s estate. 

(e) The Company, the Committee and the Trustee shall have no duty to determine whether a Beneficiary designation or spousal consent made
pursuant to this Section 6.2 was an informed designation or consent or was freely given, and shall be entitled to rely upon the Beneficiary form filed with the Committee or its delegate, as well as such other documents as may be required
pursuant to Section 6.2(i), and shall be under no duty or obligation to attempt to protect the rights of a spouse or former spouse of a Participant. 

(f) Upon the death of a Participant during his employment, or in the event that the Committee shall determine that a Participant has suffered
a Disability while an Employee of the Company, the Committee shall direct the Trustee to make a distribution of the Participant’s Distributable Benefit to the Participant’s Beneficiary determined under this Section 6.2 (in the event
of death), or to the disabled Participant (in the event of Disability). 
 (g) Except as may be required in accordance with
Section 6.4, the form of the Distributable Benefit shall be a cash lump sum distribution, payable within one hundred twenty (120) days (or as soon thereafter as is reasonable for administrative purposes) after the close of the Plan Year in
which the death of the Participant occurs, or in which he is determined to be Disabled, as the case may be, subject to proof of death or Disability satisfactory to the Committee. In no event shall the payment to a Participant who has suffered a
Disability be made later than such Participant’s Required Payment Commencement Date. 
 (h) Upon the death of a former Participant
after his retirement, Disability or other termination of employment, but prior to the distribution of his Distributable Benefit to which he is entitled, the Committee shall direct the Trustee to make a distribution of the balance to which the
deceased Participant was entitled, to the Participant’s Beneficiary determined under this Section 6.2, such payment to be made within one hundred twenty (120) days (or as soon thereafter as is reasonable for administrative purposes)
after the close of the Plan Year in which the death of the Participant occurs, notwithstanding any elections previously made by the Participant. 

(i) The Committee or Trustee, or both, may require (and rely upon) the execution and delivery of such documents, papers and receipts as the
Committee or Trustee may determine necessary or appropriate in order to establish the fact of death of the deceased Participant and of the right and identity of any Beneficiary or other person or persons claiming any benefits.

 6.3 In-Service Withdrawals. 

(a) Age 59  1⁄2 Withdrawals. A Participant
shall be entitled to make withdrawals from the vested portion of his Accounts including any earnings thereon, after the date on which he attains the age of 59-1/2 even though his employment with the Company has not yet been terminated. 

(b) Hardship Withdrawal. A Participant may withdraw amounts attributable to Rollover Contributions, Elective Deferrals and Catch-Up
Contributions made to this Plan prior to attaining age 59 1/2, upon incurring a hardship as determined by the Committee, provided that no amount representing earnings in such account after December 31, 1988, may be withdrawn. A withdrawal will
be deemed on account of hardship only if the distribution is made on account of an immediate and heavy financial need and is necessary to satisfy such financial need. Any withdrawal made pursuant to this Section 6.3(b) shall be made in
accordance with rules prescribed by the Committee that are consistent with Regulations under Code Section 401(k), and the following rules: 

(i) The determination of whether an Employee has an immediate and heavy financial need is to be made by the Committee on the basis of all
relevant facts and circumstances. A distribution will be deemed to be made on account of an immediate and heavy financial need of the Employee if the distribution is on account of: 

(1) Medical expenses for the Employee, his spouse, his dependents or his primary Beneficiary (provided that such Beneficiary is an
individual) that would be deductible under Code Section 213(d) (determined without regard to whether the expenses exceed 7.5% of adjusted gross income); 

(2) Purchase of the principal residence for the Employee (excluding mortgage payments); 

(3) Payment of tuition and related education fees for the next twelve months of post-secondary education for the Employee, the
Employee’s spouse, children or dependents (as defined in Code Section 152, without regard to Sections 152(b)(1), (b)(2) and (d)(1)(B)) or the Employee’s primary Beneficiary (provided that such Beneficiary is an individual); 

(4) The need to prevent the eviction from the Employee’s principal residence or foreclosure on the mortgage of the Employee’s
principal residence; 
 (5) Payments for burial or funeral expenses for the Employee’s deceased parent, spouse, children, dependents
(as defined in Code Section 152, without regard to Section 152(d)(1)(B)) or primary Beneficiary (provided that such Beneficiary is an individual); 

  
 27 

 (6) Expenses for the repair of damages to the Employee’s principal residence that would
qualify for the casualty deduction under Code Section 165 (determined without regard to whether the loss exceeds 10% of adjusted gross income); or 

(7) Any other event described in Treasury Regulations or rulings as an immediate and heavy financial need and approved by the Committee as a
reason for permitting distribution under this Section. 
 (ii) To receive a hardship withdrawal, the following requirements must first be
met by the applicant: 
 (1) The applicant must apply in the manner required by the Committee and including any required signatures and
certifications; 
 (2) The applicant must have withdrawn, or must withdraw at the same time that an application for hardship withdrawal is
submitted, all eligible in-service withdrawals from balances in this Plan and all other Company retirement plans; 
 (3) The applicant must
have applied for all eligible loans from those Company retirement plans which permit Participant loans; 
 (4) The hardship withdrawal
cannot be less than $500.00; and 
 (5) The applicant must suspend all Elective Deferrals to all qualified plans of deferred compensation
maintained by the Company or an Affiliated Company for six (6) months after receiving the hardship withdrawal pursuant to rules prescribed by the Committee. 

(iii) The withdrawal shall be made pro rata from the subaccounts in which the Participant’s Account is invested. 

(iv) The timing of the payment of the withdrawal shall be made as soon as practicable following the request in accordance with the rules
established by the Committee. 
 (c) Withdrawal of Voluntary Accounts and Rollover Accounts. 

(i) A Participant shall be entitled to a distribution from his Voluntary Account or Rollover Account (up to the full balance thereof on the
Applicable Valuation Date) prior to the termination of his employment with the Company or an Affiliated Company, subject to reasonable restrictions imposed by the Committee with respect to the frequency and amount of such withdrawals. 

(ii) All withdrawals from Voluntary Accounts or Rollover Accounts shall be paid in cash as soon as administratively practicable following the
receipt of a request for withdrawal from the Participant. 
 (iii) In the event that a Participant has elected to have his Voluntary
Account or Rollover Account invested in more than one investment alternative pursuant to the 

  
 28 

 
rules of Section 3.8, then a Participant withdrawing less than the entire balance in his Voluntary Account or Rollover Account will receive a pro rata distribution from among such investment
alternatives. 
 (d) Withdrawals by Qualified Reservists. 

If a Participant who is a “Qualified Reservist” is ordered or called to active military duty, and such active duty is for a duration
of 180 days or more or for an indefinite period, then the Participant may elect to withdraw all or a portion of his Plan Account attributable to his pre-tax Elective Deferrals and Roth Deferrals made to this Plan. Such withdrawal can be made at any
time during the period beginning on the date of such order or call to active duty and ending on the date that such active duty ceases. For purposes of withdrawals under this Section 6.3(d), (1) a “Qualified Reservist” is a
reservist or national guardsman as defined in 37 U.S.C. 101(24), and (2) a Participant’s Plan Account shall be valued as of the Valuation Date immediately following the Committee’s acceptance of the Participant’s written
application for a distribution under this Section 6.3(d). 
 6.4 Distribution of Survivor Annuity Subaccount. Notwithstanding
the preceding sections of this Article VI: 
 (a)(i) A Participant’s Distributable Benefits attributable to his Survivor Annuity
Subaccount shall be paid in the form of a distribution of an annuity contract (purchased from a legal reserve life insurance company with the aggregate balance in the Participant’s Survivor Annuity Subaccount) providing a joint and fifty
percent (50%) survivor annuity (“Joint and Survivor Annuity”) if the Participant was married at the time of retirement or at the time the Distributable Benefit would otherwise be paid pursuant to Section 6.1. The Participant,
with the consent of his spouse, may, however, elect not to receive a Joint and Survivor Annuity as provided in this Section 6.4, in which case the Participant’s benefit will be paid in accordance with the otherwise applicable provisions of
this Article VI. 
 (ii) The Joint and Survivor Annuity payable under this Section 6.4 shall provide for payments to the Participant
in equal monthly payments, beginning in the month following the month in which the Participant’s Normal Retirement Date occurs (or would occur in the event of termination of employment prior to such date), and ending the payment for the
calendar month in which his death occurs, and, if the Participant dies after his benefit commences and is survived by a spouse entitled to survivor benefits under such Joint and Survivor Annuity, such spouse shall receive monthly payments of fifth
percent (50%) of the Participant’s benefit beginning with the payment for the calendar month following the month in which the Participant died and ending with the payment for the calendar month in which the spouse dies. 

(iii) A Participant may elect with the consent of his spouse, in the manner prescribed by the Committee, not to receive a Joint and Survivor
Annuity in which case the Participant shall receive his benefit as otherwise provided in this Article VI. This election may be made or revoked at any time during the one hundred and eighty (180)-day period ending on the annuity starting date but
shall become irrevocable once the Participant’s benefit commences (i.e., once the annuity contract is distributed. The election may be made only with 

  
 29 

 
the consent of the spouse, which consent must acknowledge the effect of such election and must be given in writing witnessed by a member of the Committee, a representative thereof, or a notary
public. Spousal consent may be waived by the Committee only if it is established to the satisfaction of the Committee that such consent cannot be obtained because the Participant has no spouse, because the spouse cannot be located, or because of
such other circumstances as are prescribed in regulations issued by the Secretary of the Treasury. Consent obtained or waived under this Section 6.4(a) shall be effective only with respect to the spouse to whom such consent applied. 

(iv) A Participant who is entitled to receive a distribution in the form of a Joint and Survivor Annuity may elect to instead receive the
Distributable Benefits attributable to his Survivor Annuity Subaccount in the form of a distribution of an annuity contract (purchased from a legal reserve life insurance company with the aggregate balance in the Participant’s Survivor Annuity
Subaccount) providing a joint and seventy-five percent (75%) survivor annuity. Such annuity is intended to satisfy the requirement set forth in Code Section 417 that the Plan make available a qualified optional survivor annuity. 

(b) If a Participant dies before commencement of payment of his Distributable Benefit attributable to his Survivor Annuity Subaccount, the
Participant’s surviving spouse shall (unless such surviving spouse elects to receive a lump sum distribution as set forth in this subsection (b)) receive a distribution of an annuity contract (provided from a legal reserve life insurance
company with the aggregate balance in the Participant’s Accounts) providing an immediate annuity for the life of the surviving spouse (“Preretirement Survivor Annuity”). The surviving spouse may waive the Preretirement Survivor
Annuity and instead receive a lump sum distribution at any time before the benefit commences, but distribution in the form of an annuity shall become irrevocable once the benefit commences (i.e., once the annuity contract is distributed). 

(c) Survivor benefits under Section 6.4(a) or (b) shall not be paid to any surviving spouse (or former spouse) who was neither
(i) married to the Participant throughout the one-year period ending on the earlier of the Participant’s annuity starting date or the date of the Participant’s death nor (ii) deemed to be married at such time pursuant to Code
Section 417(d)(2). Instead, the amount attributable to the Survivor Annuity Subaccount shall be paid in a lump sum to the Participant’s Beneficiary. 

(d) Required Minimum Distributions. 

(i) General. All distributions required under Section 6.4 of the Plan will be determined and made in accordance with the Treasury
Regulations under Code Section 401(a)(9), and the requirements of this Section 6.4(d) will take precedence over any inconsistent provisions of the Plan. Notwithstanding the foregoing, distributions may be made under a designation made
before January 1, 1984, in accordance with Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act (TEFRA) and the provisions of the Plan that relate to Section 242(b)(2) of TEFRA. 

(ii) Death of Participant before Distributions Begin. If the Participant dies before distribution begins, and the Participant’s
surviving spouse is the Participant’s sole 

  
 30 

 
designated Beneficiary, then distributions to the surviving spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant dies.
Unless a lump sum distribution is elected pursuant to Section 6.4(b) or a lump sum is payable pursuant to Section 6.5(f), the Participant’s interest shall be distributed in the form a Preretirement Survivor Annuity purchased from an
insurance company. If the Participant’s interest is distributed in the form of a Preretirement Survivor Annuity purchased from an insurance company, distributions thereunder will be made in accordance with the requirements of Code
Section 401(a)(9) and the Treasury Regulations. Distributions to a Beneficiary other than the surviving spouse of the Participant shall be made pursuant to Section 6.1. 

6.5 Special Rules Relating to Distributions. 

(a) Form. Subject to the Participant’s right under Sections 6.1(d), 6.1(e) and Section 6.5(d) to elect to receive a Company
Stock distribution calculated under the provisions of Section 6.5(e), a Participant’s Distributable Benefit shall be distributed in the form of cash or, if elected in accordance with Section 6.6(b), by trustee-to-trustee transfer.

 (b) Amount. For purposes of determining the amount of Distributable Benefit that will be distributed to a Participant or
Beneficiary pursuant to the rules of this Article VI, the value of the Participant’s Account shall be determined in accordance with rules prescribed by the Committee. However, the value of the Participant’s Account shall be increased or
decreased (as appropriate) by any contributions or distributions properly allocable under the terms of this Plan to his Account that occurred on or after the Applicable Valuation Date or for any other reason were not otherwise properly reflected in
the valuation of his Account on such Valuation Date. 
 (c) Liability. Neither the Committee, the Company, nor the Trustee shall have
any responsibility for any increase or decrease in the value of a Participant’s Account as a result of any valuation made under the terms of this Plan after the date of his termination of employment and before the date of the distribution of
his Account to him or his Beneficiary. Also, neither the Committee, the Company, nor the Trustee shall have any responsibility for failing to make any interim valuation of a Participant’s Account between the date of distribution to the
Participant of his Account and the immediately preceding Valuation Date, even though the Plan Assets may have been revalued in that interim for a purpose other than to revalue the Accounts under this Plan. 

(d) Right to Receive Company Stock. Each Participant shall have the right (pursuant to procedures established by the Committee) to
elect to receive his Distributable Benefit in the form of a Company Stock distribution as calculated under Section 6.5(e). This election by the Participant shall be made in writing or as otherwise permitted by Section 11.9, shall be
irrevocable when made unless the Committee shall approve a revocation thereof, and shall operate to require the Committee to cause the Participant’s Distributable Benefit to be made in the form of a Company Stock distribution as calculated
under Section 6.5(e). 
 (e) Distribution of Company Stock. A Company Stock Distributable Benefit shall be governed by the
following rules: 

  
 31 

 (i) The amount of such a distribution shall be the number of whole shares of Company Stock that
can be purchased, either by a stated percentage or by the dollar value of the Participant’s Plan balance (determined as of the Applicable Valuation Date), with the remainder of the value of the Participant’s Plan balance distributable in
the form of cash. 
 (ii) Any Company Stock Distributable Benefit under this Plan is limited to, and shall be deemed made from, the assets
of the ESOP Fund. 
 (f) Distributable Benefit Under $5,000. If the present value of the Participant’s Distributable Benefit
determined as of the Participant’s termination date, death or any subsequent Valuation Date does not exceed $5,000, the Participant (or Beneficiary in the event of the Participant’s death) shall receive a single sum distribution of the
entire value of the Participant’s Distributable Benefit within twelve months (or as soon thereafter as is reasonable for administrative purposes) following the Participant’s termination of employment, or as soon as practicable following
receipt of notice of Participant’s death or such subsequent Valuation Date, whichever is applicable; provided, however, that with respect to a Participant’s Survivor Annuity Subaccount, no distribution shall be made under this subsection
(f) after the Participant’s annuity starting date unless the Participant and spouse consent in writing to such distribution. For this purpose, the annuity starting date shall mean the first day of the first period for which an amount is
payable as an annuity or, in the case of a disability benefit, the first day of the first period for which a benefit is to be received by reason of a Disability. Notwithstanding anything to the contrary contained in the foregoing, in the event that
the present value of a Participant’s Distributable Benefit is greater than $1,000 but equal to or less than $5,000, if the Participant does not affirmatively elect to have such distribution either (1) paid directly to an eligible
retirement plan specified by the Participant in a direct rollover, or (2) to receive the distribution directly, then the Committee shall pay the distribution in a direct rollover to an individual retirement plan designated by the Committee. If
the Participant’s Distributable Benefit is zero, the Participant shall be deemed to have received a distribution of his entire Distributable Benefit. Such distribution shall not require consent by the Participant or the Participant’s
spouse. 
 (g) Facility of Payment. If any payee under the Plan is a minor or if the Committee reasonably believes that any payee is
legally incapable of giving a valid receipt and discharge for any payment due him, the Committee may have the payment, or any part thereof, made to the person (or persons or institution) whom it reasonably believes is caring for or supporting the
payee, unless it has received due notice of claim therefore from a duly appointed guardian or committee of the payee. Any payment shall be a payment from the Accounts of the payee and shall, to the extent thereof, be a complete discharge of any
liability under the Plan to the payee. 
 (h) Distribution to Alternate Payees. If an Alternate Payee is entitled to a distribution
of benefits from this Plan pursuant to a qualified domestic relations order, as defined in Section 11.5, the benefits payable to such Alternate Payee shall be distributed pursuant to such qualified domestic relations order under rules or
procedures described by the Committee. If permitted by applicable law and regulations, the Committee may require or permit immediate distribution of such benefits to an Alternate Payee at any time following the determination by the Committee that
such an order is a qualified domestic relations order. In the event that an 

  
 32 

 
Alternate Payee dies prior to receipt of the amounts due him from an Alternate Payee Account, such amounts shall be distributed to the estate of the Alternate Payee as soon as practicable
following the date such amounts would have been distributed to such Alternate Payee unless the order provides that the amounts shall revert back to the Participant. 

(i) Compliance with Section 401(a)(9). 

(i) Notwithstanding anything to the contrary contained herein, the distribution options under this Plan shall comply with Code
Section 401(a)(9) (including the incidental death benefit requirements of Code Section 401(a)(9)(G)) and Treasury Regulations Sections 1.401(a)(9)-2 through 1.401(a)(9)-9, which are hereby incorporated by this reference as a part of this
Plan. Any inconsistencies in this Plan shall be overruled by Code Section 401(a)(9) and its underlying Treasury Regulations. Accordingly, unless otherwise permitted by law, the interest of each Participant shall commence to be distributed no
later than such Participant’s Required Payment Commencement Date. 
 (ii) For purposes of determining the distributions under
Section 6.1(c) to Participants who elect to receive a minimum required distribution for any distribution calendar year, the following shall apply: 

(1) During the Participant’s lifetime, the minimum amount that will be distributed for each distribution calendar year is the lesser of:

 (A) the quotient obtained by dividing the Participant’s account balance by the distribution period in the Uniform Lifetime Table
set forth in Section 1.401(a)(9)-9 of the Treasury Regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or 

(B) if the Participant’s sole designated Beneficiary for the distribution calendar year is the Participant’s spouse, the quotient
obtained by dividing the Participant’s account balance by the number in the Joint and Last Survivor Table set forth in Section 1.401(a)(9)-9 of the Treasury Regulations, using the Participant’s and spouse’s attained ages as of
the Participant’s and spouse’s birthdays in the distribution calendar year. 
 (2) Required minimum distributions will be
determined under this Article VI beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death. Required minimum distributions following the
Participant’s death shall be made in a lump sum as set forth in Section 6.2. 
 (3) The required minimum distribution for any
distribution calendar year shall be made pro rata from the subaccounts in which the Participant’s Account is invested. 
 (4) For
purposes of this Section 6.5(i), the following definitions shall apply: 

  
 33 

 (A) A “distribution calendar year” is a calendar year for which a minimum distribution
is required. For distributions beginning before the Participant’s death, the first distribution calendar year is the calendar year immediately preceding the calendar year which contains the Participant’s required beginning date. The
required minimum distribution for the Participant’s first distribution calendar year will be made on or before the Participant’s Required Payment Commencement Date. The required minimum distribution for other distribution calendar years,
including the required minimum distribution for the distribution calendar year in which the Participant’s Required Payment Commencement Date occurs, will be made on or before December 31 of that distribution calendar year. 

(B) The “Participant’s account balance” is the account balance as of the last valuation date in the calendar year immediately
preceding the distribution calendar year (valuation calendar year) increased by the amount of any contributions made and allocated or forfeitures allocated to the account balance as of dates in the valuation calendar year after the valuation date
and decreased by distributions made in the valuation calendar year after the valuation date. The account balance for the valuation calendar year includes any amounts rolled over or transferred to the Plan either in the valuation calendar year or in
the distribution calendar year if distributed or transferred in the valuation calendar year. 
 6.6 Direct Rollovers. 

(a) Notwithstanding any provision of the Plan to the contrary that would otherwise limit a distributee’s election under this
Section 6.6, a “distributee” (as defined below) may elect, at the time and in the manner prescribed by the Committee, to have any portion of an “eligible rollover distribution” (as defined below) made payable directly to an
“eligible retirement plan” (as defined below) specified by the distributee in a “direct rollover” (as defined below). 

(b) For purposes of this Section 6.6: 

(i) An “eligible rollover distribution” is any distribution of all or any portion of the balance to the credit of the distributee,
except that an eligible rollover distribution does not include: (a) any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancies) of the
distributee or the distributee’s designated Beneficiary, or for a specified period of 10 years or more; (b) any distribution to the extent such distribution is required under Code Section 401(a)(9); (c) the portion of any
distribution that is not includible in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to employer securities) unless such portion is (I) not attributable to the distributee’s Roth
Deferral Account and transferred in a direct trustee-to-trustee transfer to a qualified trust which is part of a plan which is a defined contribution plan and which agrees to separately account for amounts so transferred, including separate
accounting for the portion which is includible in gross income and the portion which is not so includible, or (II) attributable to the distributee’s Roth Deferral Account and transferred 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; (d) any hardship distribution described in Section 401(k)(2)(B)(i)(IV) of the Code; and (e) any
other type of distribution which the Internal Revenue Service announces (pursuant to 

  
 34 

 
regulation, notice, or otherwise) is not an eligible rollover distribution. If approved by the Committee in its sole discretion, an eligible rollover distribution may include active loans from
the Participant’s Accounts. 
 (ii) An “eligible retirement plan” is a retirement plan that accepts the distributee’s
eligible rollover distribution and is an individual retirement account described in Code Section 408(a), an individual retirement annuity described in Code Section 408(b), an annuity plan described in Code Section 403(a), an annuity
contract as described in Code Section 403(b), a qualified trust described in Code Section 401(a) or an eligible plan under Code Section 457 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. However, 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 Code
Section 414(p), an eligible retirement plan is an individual retirement account or individual retirement annuity. Notwithstanding the foregoing, a direct rollover of a distribution from a Roth 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. An “eligible retirement plan” with respect to any portion of the distribution that is not attributable to the distributee’s Roth Deferral Account shall also include a Roth IRA as described in
Section 408A of the Code, provided that the distributee is not restricted from making such a rollover from this Plan to a Roth IRA pursuant to Code Section 408A(c). 

(iii) A “distributee” includes an employee or former employee. In addition, the employee’s or former employee’s surviving
spouse and the employee’s or former employee’s spouse or former spouse who is the alternative payee under a qualified domestic relations order, as defined in Section 414(p) of the Code, are distributees with regard to the interest of
the spouse or former spouse. In addition, a Beneficiary other than the Participant’s or former Participant’s surviving spouse or the Participant’s or former Participant’s spouse or former spouse who is the Alternate Payee under a
qualified domestic relations order, as defined in Code Section 414(p), is a distributee with regard to the interest of the Participant, subject to the limitation in Section 6.6(c) for such a Beneficiary that an eligible retirement plan is
an individual retirement account that will be treated as an inherited individual retirement account Code Section 402(c)(11). 
 (iv) A
“direct rollover” is a payment by the Plan to the eligible retirement plan specified by the distributee. 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, (a) such portion as is not attributable to the distributee’s Roth Deferral Account may be transferred only to an individual retirement account or annuity described
in Code Sections 408(a) or 408(b), to a qualified plan described in Code Sections 401(a) or 403(a) 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, or to a Roth IRA as described in Section 408A of the Code, provided that the distributee is not restricted from making such a rollover from this Plan to a Roth IRA
pursuant to Code Section 408A(c), and (b) such portion as is attributable to the distributee’s Roth Deferral Account may be 

  
 35 

 
transferred only 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. 
 (c) If the designated Beneficiary (within the meaning of Code Section 401(a)(9)(E)) of a deceased Participant is not the
spouse of the Participant, the Beneficiary may elect that a transfer of the survivor benefit be made directly to an individual retirement account established on behalf of the Beneficiary. Provided that the distributed amount satisfies all the
requirements to be an eligible rollover distribution (other than the requirement that the distribution be made to the Participant or the Participant’s spouse) and is made to an individual retirement account that will be treated as an inherited
individual retirement account pursuant to the provisions of Code Section 402(c)(11), such transfer shall be treated as a direct rollover.

favorable to the Plan than the price determined under Section 407(e)(1) of ERISA. No commission shall be charged to the Plan in connection with any such sale or acquisition. The determination as to whether or not such a sale or acquisition
satisfies the requirements of this Section 7.6 shall be made by the Committee.

and/or ESOP Accounts of all Eligible Participants (as defined in Section 3.4(c)) for the Plan Year in the proportion that the Compensation of each such Eligible Participant (regardless of Fringe Rate Group) bears to the total compensation of
all such Eligible Participants, (ii) be used to offset Company Matching Contributions for such Plan Year and allocated to the Matching Contribution Accounts of those Participants who are entitled to receive an allocation of Company Matching
Contributions for the Plan Year according to the rules of Section 3.3, or (iii) be used to pay Plan expenses as provided in Section 8.3. 

(c) Pending allocation, all forfeitures shall be accounted for in the same manner as Company Contributions and shall be adjusted for income,
gain or loss on such forfeitures. 
 (d) Notwithstanding anything to the contrary herein, amounts forfeited under the Plan may be used by
the Company to satisfy reinstatements due to military leave or amounts owed to the Plan as a result of an error in the operation of the Plan. 

8.2 Reinstatement of Forfeitures. 

(a) If a Participant who was partially vested under Section 5.2(a) is reemployed by the Company or an Affiliated Company on (or before)
the Anniversary Date of the Plan Year in which his fifth consecutive Break in Service occurs, the Participant shall be entitled to have the entire portion of his Matching Contribution Account, his Profit Sharing Account, his ESOP Account and his
PSRP Profit Sharing Account (including the nonvested portion(s) of such Account(s)) reinstated by repaying the total amount distributed to him. Such reinstatement shall be made from current forfeitures or, if necessary, from Company

  
 39 

 
Contributions and shall not be treated as an Annual Addition. However, this repayment must be made prior to the earlier of (1) five years from the date of reemployment or (2) five
consecutive Breaks in Service after the distribution of the Vested Interest in his Plan Account following such termination of employment, provided he is an Eligible Employee during that period. If such repayment is not made, then the previously
forfeited amounts shall not be restored. 
 (b) In the case of a repayment made pursuant to this Section 8.2: 

(i) The Participant shall not be required to pay any interest charge upon the amounts repaid by him; and 

(ii) The nonvested portion(s) of his applicable Account(s) as set forth in subsection (a) above (which was not distributed to him) shall
not be adjusted for gains or losses during the period between the forfeiture and the repayment of the distributed amount. 
 (iii) In the
case of a Participant with no Vested Interest in his applicable Account(s) as set forth in subsection (a) above who is reemployed prior to incurring five consecutive Breaks in Service, his entire nonvested Account(s) (unadjusted for gains or
losses during the period between the date of his forfeiture and the date of his reemployment) shall be reinstated upon his reemployment, without regard to the repayment requirement of subsection (a) above. 

(iv) In no event shall a Participant who has received a distribution which includes the balance in his Plan Account, Voluntary Account,
TRASOP Account, CODA Account, Roth Deferral Account and/or Rollover Account be entitled either to repay the Plan or to have the balance in such Plan Account, Voluntary Account, TRASOP Account, CODA Account, Roth Deferral Account and/or Rollover
Account reinstated upon reemployment by the Company or an Affiliated Company. However, if the previous distribution otherwise qualifies for a Rollover Contribution, the Participant may make a Rollover Contribution upon reemployment. 

8.3 Allocation of Income or Loss on Unallocated Company Contributions; Company Contributions to Defray Plan Expenses. At the time
Company Contributions are allocated to Plan Accounts, the income, gain or loss on unallocated Company Contributions, adjusted for any Plan expenses paid or accrued as of the end of the Plan Year preceding the actual allocation date (except for Plan
expenses paid through Company Contributions pursuant to the following sentence), shall be allocated to those Participants eligible to receive an allocation of Profit Sharing Contribution or ESOP Contribution for such Plan Year, pro rata, according
to each such Participant’s entitlement to such allocation. The Company may, in its discretion, (i) make a Plan Contribution at any time for the purpose of defraying Plan expenses, or (ii) use forfeitures of Matching Contribution
Accounts, Profit Sharing Accounts, PSRP Profit Sharing Accounts and/or ESOP Accounts for the purpose of defraying Plan expenses. Such contribution and/or forfeitures shall be used to defray Plan expenses and shall not be allocated to Accounts of
Participants. 
 8.4 Accounting Procedures. The Committee shall establish accounting procedures for the purpose of making the
allocations, valuations and adjustments to Accounts provided for 

  
 40 

 
in this Article VIII, as well as the implementation of investment direction by Participants pursuant to Section 3.8 and transfers between or distributions from subaccounts established
pursuant to Section 3.8. From time to time the Committee may modify such accounting procedures for the purpose of achieving equitable, nondiscriminatory, and administratively feasible allocations among the Accounts in accordance with the
general concepts of the Plan and the provisions of this Article VIII. 
 A Participant, Beneficiary or Alternate Payee shall have no
contractual or other right to have a particular accounting procedure or convention apply, or continue to apply, and the Committee shall be free to alter any such procedure or convention without obligation to any Participant, Beneficiary or Alternate
Payee, consistent with the requirements of Code Section 411(d)(6). 
 8.5 Suspended Participants. The Accounts of each Suspended
Participant shall be held intact and shall be valued on each Valuation Date as provided in Section 3.9, but shall not receive any allocation of Company Contributions or forfeitures; provided, however, that if the Participant completes, during
the Plan Year in which he becomes a Suspended Participant, 850 or more Hours of Service during such Plan Year, his Profit Sharing Account shall participate in the allocation of Company Contributions and forfeitures of Profit Sharing Contribution or
ESOP Contribution for such Plan Year, if he otherwise would have been eligible for such an allocation or if such Suspended Participant’s employment terminated during such Plan Year as a result of death, retirement on or after the Normal
Retirement Date, Disability or involuntary lay-off (other than for cause) as determined by the Committee in its sole discretion. 
 8.6
Accounting for Interest of an Alternate Payee. In the event an Alternate Payee is awarded an interest in the Plan benefits of a Participant pursuant to a qualified domestic relations order, as defined in Section 11.5, such interest shall be
separated into one or more separate Accounts and accounted for under rules prescribed by the Committee, pending distribution to the Alternate Payee.

 ARTICLE IX 

OPERATION AND ADMINISTRATION OF THE PLAN; 

VOTING AND OTHER RIGHTS OF COMPANY STOCK 

9.1 Members. The Committee is the Science Applications International Corporation Retirement Plans Committee. The members of the
Committee shall be appointed by the Board of Directors and shall hold office until resignation, death, removal by the Board of Directors or the date the member ceases to be an employee of the Company. A member of the Committee may resign by
delivering a written notice of resignation to the Board of Directors. The Board of Directors may remove any member by delivering a certified copy of its resolution of removal to such member. Vacancies in the membership of the Committee shall be
filled by the Board of Directors. 
 9.2 Committee Action. A majority of the members of the Committee as constituted at any time
shall constitute a quorum, and any action by a majority of the members present at any meeting, or authorized by a majority of the members in writing without a meeting, shall constitute the action of the Committee and be binding upon the same as if
all members had joined therein. A member of the Committee shall not vote or act upon any matter which relates solely to himself as a Participant. Any member or members of the Committee designated by the Committee may execute any certificate or other
written direction on behalf of the Committee. The Trustee or any third person dealing with the Committee may conclusively rely upon any certificate or other written direction so signed until the Committee shall file with the Trustee a written
revocation of the authorization of the designated members. 
 9.3 Rights and Duties. 

(a) The Company shall be the Plan Administrator (as defined in Section 3(16)(A) of ERISA). The Company delegates its duties under the
Plan to the Committee. The Committee shall act as the Fiduciary with respect to control and management of the Plan for purposes of ERISA on behalf of the Participants and their Beneficiaries, shall enforce the Plan in accordance with its terms,
shall be charged with the general administration of the Plan, and shall have all powers necessary to accomplish its purposes, including, but not limited to, the following: 

(i) To allocate fiduciary responsibilities (other than trustee responsibilities) among the named Fiduciaries and to designate one or more
other persons to carry out fiduciary responsibilities (other than trustee responsibilities). The term “trustee responsibilities” as used herein shall have the meaning set forth in Section 405(c) of ERISA. The preceding provisions of
this Section 9.3(a) shall not limit the authority of the Committee to appoint one or more Investment Managers in accordance with Section 9.3(b). 

(ii) To designate agents to carry out responsibilities relating to the Plan, other than fiduciary responsibilities. 

(iii) To employ such legal, actuarial, medical, accounting, clerical, administrative and ministerial and other assistance as it may deem
appropriate in carrying out the provisions of this Plan, including one or more persons to render advice with regard to any responsibility any named Fiduciary or any other fiduciary may have under the Plan. 

  
 42 

 (iv) To establish rules and regulations from time to time for the conduct of the
Committee’s business and the administration and effectuation of this Plan. 
 (v) To administer, interpret, construe and apply this
Plan and the Plan’s claims procedure and to decide all questions which may arise or which may be raised under this Plan by any employee, Participant, former Participant, Beneficiary, Alternate Payee or other person whatsoever, including but not
limited to all questions relating to eligibility to participate in the Plan, the amount of service of any Participant, and the amount of benefits to which any Participant or his Beneficiary may be entitled on or after the Effective Date hereof. 

(vi) To determine the manner in which the assets of this Plan, or any part thereof, shall be distributed. 

(vii) Subject to the restrictions hereunder, including the requirements of subsection 3.8(a)(i)(1), to select alternative investment options
from which Participants may select from in determining investment of their Accounts, and to establish rules and procedures regarding such investment options. 

(viii) To satisfy accounting, auditing, record keeping, insurance, bonding and reporting and disclosure requirements. 

(ix) To establish claims procedures consistent with regulations of the Secretary of Labor for presentation of claims by Participants and
Beneficiaries for Plan benefits, consideration of such claims, review of claim denials and issuance of a decision on review. Such claims procedures shall at a minimum consist of the following: 

(1) The Committee shall notify Participants and, where appropriate, Beneficiaries of their right to claim benefits under the claims
procedures, and may, if appropriate, make forms available for filing of such claims, and shall provide the name of the person or persons with whom such claims should be filed. 

(2) The Committee shall establish procedures for action upon claims initially made and the communication of a decision to the claimant
promptly and, in any event, not later than 90 days after the claim is received by the Committee, unless special circumstances require an extension of time for processing the claim. If an extension is required, written notice of the extension shall
be furnished to the claimant prior to the end of the initial 90-day period, which notice shall indicate the reasons for the extension and the expected decision date. The extension shall not exceed 90 days. The claim may be deemed by the claimant to
have been denied for purposes of further review described below in the event a decision is not furnished to the claimant within the period described in the three preceding sentences. 

(3) Every claim for benefits which is denied shall be denied by written notice setting forth in a manner calculated to be understood by the
claimant (i) the specific reason or reasons for denial, (ii) specific references to any provisions of the Plan on which the denial is based, (iii) a description of any additional material or information necessary

  
 43 

 
for the claimant to perfect his claim with an explanation of why such material or information is necessary, and (iv) an explanation of the procedure for further reviewing the denial of the
claim under the Plan, including a statement of the right of the claimant to bring an action under Section 502(a) of ERISA following an adverse benefit determination on review. 

(4) The Committee shall establish a procedure for review of claim denials, such review to be undertaken by the Committee. The review given
after denial of any claim shall be a full and fair review with the claimant or his duly authorized representative having 65 days after receipt of denial of his claim to request such review. Claimant shall have the right to submit documents, records,
issues, comments and other information in writing which relates to the claim for benefits, all of which shall be taken into account regardless of whether it was submitted in the initial benefit determination. The claimant shall be provided upon
request and at no charge reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits. 

(5) The Committee shall establish a procedure for issuance of a decision by the Committee not later than 60 days after receipt of a request
for review from claimant unless special circumstances (i.e., such as the need to hold a hearing) require an extension of time for processing the claim. If the Committee determines that an extension of time for processing is required, written notice
of the extension shall be furnished to the claimant prior to the termination of the initial 60-day period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render
the determination on review. In no event shall such extension exceed a period of 60 days from the end of the initial period. The decision on review shall be in writing and shall include specific reasons for the decision written in a manner
calculated to be understood by the claimant with specific reference to any provisions of the Plan on which the decision is based. 
 (6)
Notwithstanding any other provision of this Plan, no person claiming any benefit under this Plan may commence any legal action in connection therewith until all of the claim and appeal procedures specified in this Section 9.3(a)(ix) have been
commenced and completed. In addition, no action may be commenced with respect to or arising from any claim for benefits against the Plan (or the Committee, the Company or any of its or their agents) more than one hundred eighty (180) days after
the Participant, Beneficiary or other individual, as the case may be (“Claimant”) is first given a written notice of the denial of his or her appeal by the Committee. Unless the Committee specifically determines otherwise, this period
shall not be extended even if the Committee again considers the matter after the initial denial. This limitations period shall apply to all actions arising out of or relating to a claim for benefits including, but not limited to, any action under
Section 502(a)(1)(B) of ERISA and any action under Section 502(a)(3) of ERISA to the extent said claim relates to the provision of benefits or rights under this Plan. 

(x) To execute any amendment to the Plan which is necessary to maintain the qualification and tax exempt status of the Plan under the Code
and ERISA, and any other amendments to the Plan which do not materially affect the financial obligation of the Company nor the level of benefits provided to Participants and Beneficiaries as stated in Section 10.1. 

  
 44 

 (xi) To perform or cause to be performed such further acts as it may deem to be necessary,
appropriate or convenient in the efficient administration of the Plan. 
 Any action taken in good faith by the Committee in the exercise of
its authority conferred upon it by the Plan shall be conclusive and binding upon Participants and their Beneficiaries and any Alternate Payees. 

(b) Subject to the restrictions hereunder, including the requirements of subsection 3.8(a)(i)(1), the Committee shall have the power to direct
the Trustee in writing with respect to the investment of the Trust Fund or any part thereof. Where investment authority, management and control of the Trust Fund have been delegated to the Trustee by the Committee, the Trustee shall be the Fiduciary
with respect to the investment, management and control of the Trust Fund with full discretion in the exercise of such investment, management and control. Except as otherwise provided by law, the Committee may appoint one or more Investment Managers,
as defined in Section 3(38) of ERISA, to manage all or a portion of the assets of the Plan. An Investment Manager, when appointed, shall have full power to manage the assets of the Plan for which it has responsibility, and neither the Company
nor the Committee shall thereafter have any responsibility for the management of those assets, except to the extent such power or responsibility shall have been reserved to the Company or Committee in the documents governing the relationship between
or among the Plan, the Company and the Investment Manager. Where investment authority, management and control of Trust assets is not specifically delegated to the Trustee, the Trustee shall not be a Fiduciary with respect to the investment,
management and control of Trust assets and shall be subject to the direction of the Committee or the Investment Managers appointed by the Committee, if any, regarding the investment, management and control of such assets, and in such case the
Committee, or the Investment Managers, as the case may be, shall be the Fiduciary with respect to the investment, management and control of such assets. 

(c) Each Fiduciary under the Plan and Trust shall be solely responsible for its own acts or omissions. Except to the extent required by ERISA
or the Code, no Fiduciary shall have the duty to question whether any other Fiduciary is fulfilling any or all of the responsibilities imposed upon such other Fiduciary by ERISA or by any regulations or rulings issued thereunder. No Fiduciary shall
have any liability for a breach of fiduciary responsibility of another Fiduciary with respect to the Plan or Trust unless he knowingly participates in such breach, knowingly undertakes to conceal such breach, has actual knowledge of such breach and
fails to take reasonably remedial action to remedy said breach or, through his negligence in performing his own specific fiduciary responsibilities, has enabled such other Fiduciary to commit a breach of the latter’s fiduciary responsibilities.

 9.4 Compensation, Bonding, Indemnity and Liability. 

(a) Members of the Committee shall serve without compensation unless the Board of Directors shall otherwise determine. However, in no event
shall any member of the Committee who is an Employee receive compensation from the Plan for his services as a member of the Committee. All members shall be reimbursed for any necessary or appropriate expenditures incurred in the discharge of duties
as members of the Committee. The compensation or fees, as the case may be, of all officers, agents, counsel, the Trustee, or other 

  
 45 

 
persons retained or employed by the Committee shall be fixed by the Committee. Members of the Committee and any delegates shall be bonded to the extent required by Section 412(a) of ERISA
and the regulations thereunder. Bond premiums and all expenses of the Committee or of any delegate who is an employee of the Company shall be paid by the Company and the Company shall furnish the Committee and any such delegate with such clerical
and other assistance as is necessary in the performance of their duties. The Committee is authorized at the expense of the Company to employ such legal counsel as it may deem advisable to assist in the performance of its duties hereunder. No expense
or fee of the Committee for the administration of the Plan and services in relation thereto shall be paid from the Trust assets, other than those expenses related to investments as are charged against an investment alternative established pursuant
to Section 3.9. 
 (b) To the extent permitted by law, the Company shall indemnify each member of the Board of Directors and the
Committee, and any other Employee of the Company with duties under the Plan, against expenses (including any amount paid in settlement) reasonably incurred by him in connection with any claims against him by reason of his conduct in the performance
of his duties under the Plan, except in relation to matters as to which he acted fraudulently or in bad faith in the performance of such duties. The preceding right of indemnification shall pass to the estate of such a person and shall be in
addition to any other right to which the Board of Directors or Committee member or other person may be entitled as a matter of law or otherwise. The following additional provisions apply to the right of indemnification: 

(i) The Company shall promptly pay all legal costs and expenses covered by this indemnification; 

(ii) The Company’s indemnification obligation survives the termination of the Plan, the termination of employment of any indemnified
party and the termination of an indemnified party’s fiduciary status under the Plan; 
 (iii) The Company’s indemnification
obligation is not reduced as applied to acts or omissions occurring prior to any reduction in future indemnification rights nor prior to a date at least 90 days after notice of such indemnification reduction is given to the affected indemnified
party, unless such party consents in writing; 
 (iv) The Company’s indemnification obligation exists until a final decision (by a
court or arbitrator) is rendered to the effect that the individual acted fraudulently or in bad faith; in which case the indemnified party shall be obligated to repay all benefits provided under this Section 9.4; 

(v) All related costs, claims and expenses, including those, if any, incurred in enforcing the indemnification provisions, are covered by
this indemnification obligation. 
 9.5 Manner of Administration. The Committee shall have full discretion to construe and interpret
the terms and provisions of the Plan and to make factual determinations with respect to the administration of the Plan, which interpretation, construction or determination shall be final and binding on all parties, including but not limited to the
Company and any Participant or Beneficiary or Alternate Payee. 

  
 46 

 9.6 Duty of Care. In the exercise of the powers and duties of the Committee as Plan
Administrator and Fiduciary with respect to control and management of the Plan, each member of the Committee shall use the care, prudence, and diligence under the circumstances then prevailing that a prudent person acting in a like capacity and
familiar with such matters would use in the conduct of an enterprise of a like character and with like aims. 
 9.7 Reliance Upon
Documents and Opinions. 
 (a) The members of the Committee, the Board of Directors, the Company and any Employee of the Company
delegated under the provisions hereof to carry out any fiduciary responsible under the Plan (“Delegated Fiduciary”), shall be entitled to rely upon any tables, valuations, computations, estimates, certificates and reports furnished by any
consultant, or firm or corporation which employs one or more consultants, upon any opinions furnished by legal counsel, and upon any reports furnished by the Trustee. The members of the Committee, the Board of Directors, the Company and any
Delegated Fiduciary shall not be liable in any manner whatsoever for anything done or action taken or suffered in reliance from any such consultant or firm or corporation which employs one or more consultants, trustee, or counsel. 

(b) Any and all such things done or actions taken or suffered by the Committee, the Board of Directors, the Company and any Delegated
Fiduciary shall be conclusive and binding on all Employees, Participants, Beneficiaries, Alternate Payees and any other persons whomsoever, except as otherwise provided by law. 

(c) The Committee and any Delegated Fiduciary may, but are not required to, rely upon all records of the Company with respect to any matter or
thing whatsoever, and may likewise treat those records as conclusive with respect to all Employees, Participants, Beneficiaries, and any other persons whomsoever, except as otherwise provided by law. 

9.8 Requirement of Proof. The Committee or the Company may, in its (or their) sole discretion, require satisfactory proof of any matter
under this Plan from or with respect to any Employee, Participant, Beneficiary or Alternate Payee, and no benefits under this Plan need be paid until the required proof shall be furnished. 

9.9 Voting and Other Rights of Company Stock and Leidos Stock. 

(a) All voting rights of Company Stock and Leidos Stock held in the Trust Fund shall be exercised in accordance with the following provisions:

 (i) Each Participant (which term shall include, for purposes of this Section 9.9, Beneficiaries and Alternate Payees having an
interest in an Account or fund holding Company Stock or Leidos Stock) shall be given the opportunity to instruct the Trustee confidentially on a form prescribed and provided by the Committee as to how to vote those shares (including fractional
shares) of Company Stock and Leidos Stock allocated to his Account(s) under the Plan (directly or indirectly through an interest in a Company Stock Fund or a Leidos Stock Fund) on the date immediately preceding the record date for the meeting of

  
 47 

 
shareholders of the Company or Leidos, as applicable. The Trustee shall not divulge to the Committee or the Company the instructions of any Participant. The Committee may require verification of
the Trustee’s compliance with such confidential voting instructions by an independent auditor elected by the Committee. 
 (ii) All
Participants entitled to direct such voting shall be notified by the Committee (or the Company, pursuant to its normal communications with shareholders) of each occasion for the exercise of these voting rights within a reasonable time (but not less
than the time period that may be required by any applicable state or federal law) before these rights are to be exercised. The notification shall include all information distributed by the Company or by Gemini, as applicable, to other shareholders
regarding the exercise of such rights. 
 (iii) The Participants shall be so entitled to direct the voting of fractional shares (or
fractional rights to shares). However, the Committee may, to the extent possible, direct the Trustee to vote the combined fractional shares (or fractional rights to shares) so as to reflect the aggregate direction of all Participants giving
directions with respect to fractional shares (or fractional rights to shares). 
 (iv) In the event that a Participant shall fail to direct
the Trustee, in whole or in part, as to the exercise of voting rights arising under any Company Stock or Leidos Stock allocated to his Account, then these voting rights, together with voting rights as to shares of Company Stock or Leidos Stock which
have not been allocated, shall be exercised by the Trustee in the same proportion as the number of Shares of Company Stock or Leidos Stock for which the Trustee has received direction in such matter (e.g., to vote for, against or abstain from voting
on a proposal, or to grant or withhold authority to vote for a director or directors), and the Trustee shall have no discretion in such matter, except as may be required by applicable law. 

(v) Except as provided in subsection (b) below, all rights (other than voting rights) of Company Stock and Leidos Stock held in the
Trust Fund shall be exercised in the same manner and to the same extent as provided above with respect to the voting rights of the Company Stock and the Leidos Stock, subject to the rules prescribed by the Committee, which rules, among other
matters, may prescribe that no action shall be taken with respect to shares as to which no direction is received from Participants. The Trustee shall have no discretion with respect to the exercise of any such rights, except as may be required by
applicable law. 
 (vi) Neither the Committee nor the Trustee shall make any recommendation to any Participant regarding the exercise of
the Participant’s voting rights or any other rights under the provisions of this Section 9.9, nor shall the Committee or Trustee make any recommendation as to whether any such rights should or should not be exercised by the Participant.

 (b) All responses to tender and exchange for Company Stock or Leidos Stock offers shall be made in accordance with the following
provisions: 
 (i) Each Participant shall be given the opportunity, to the extent that shares of Company Stock or Leidos Stock are
allocated to his Account, to direct the Trustee in writing as to the manner in which to respond to a tender or exchange offer with respect to 

  
 48 

 
Company Stock or Leidos Stock, and the Trustee shall respond in accordance with the instructions so received. The Trustee shall not divulge to the Committee or the Company the instructions of any
Participant. The Committee shall utilize its best efforts to timely distribute or cause to be distributed to each Participant such information as will be distributed to shareholders of the Company in connection with any such tender or exchange
offer, together with a form addressed to the Trustee requesting confidential instructions on whether or not such shares will be tendered or exchanged, including to the extent practicable, any materials distributed by Gemini to its shareholders
generally. If the Trustee shall not receive timely direction from a Participant as to the manner in which to respond to such a tender or exchange offer, the Trustee shall not tender or exchange any shares of Company Stock or Leidos Stock with
respect to which such Participant has the right of direction, and the Trustee shall have no discretion in such matter, except as may be required by applicable law. 

(ii) Unallocated shares of Company Stock and Leidos Stock and shares of Company Stock and Leidos Stock held by the Trustee pending allocation
to Participants’ Accounts shall be tendered or exchanged (or not tendered or exchanged) by the Trustee in the same proportion as shares with respect to which Participants have been given the opportunity to direct the Trustee pursuant to
subsection (i) above are tendered or exchanged, and the Trustee shall have no discretion in such matter, except as may be required by applicable law. 

9.10 Plan Expenses. 
 (a)
Except as provided in subsection (b) below, all expenses incurred in the establishment, administration and operation of the Plan, including but not limited to the expenses incurred by the members of the Committee in exercising their duties, to
the extent these expenses are not paid by the Company, shall be charged to the Trust Fund and accounted for pursuant to the provisions of Article VIII, unless paid by the Company. 

(b) Costs or expenses which are particular to a specific asset or group of assets in the Trust Fund, such as interest and brokerage charges
which are included in the cost of securities purchased by the Trustee (or charged to proceeds in the case of sales), as determined by the Committee, shall be charged or allocated in a fair and equitable manner to the Accounts, subaccounts or funds
to which those assets are allocated pursuant to rules prescribed by the Committee. 
 9.11 Multiple Fiduciary Capacity. Any person or
group of persons may serve in more than one fiduciary capacity with respect to the Plan. 
 9.12 Allocation of Fiduciary
Responsibility. 
 (a) It is the intent of the Company to comply with Section 405(c) of ERISA and to have the limitation on
liability set forth in Section 405(c)(2) of ERISA apply to the maximum extent allowed by law. 
 (b) Pursuant to Section 405(c) of
ERISA, the authority to control and manage the operation and administration of the Plan is allocated to the Committee. Except to the extent expressly provided to the contrary in this Plan document, and the Trust Agreement, the responsibilities

(d) The Trustee shall have only those responsibilities which have been specifically allocated to it under this Plan document and related Trust
Agreement, plus any “trustee responsibilities”, under Section 405(c) of ERISA, which may not legally be allocated to another person or Fiduciary. Any Investment Manager appointed pursuant to Section 9.3(b) may be granted
exclusive authority and discretion to manage and control all or any portion of the assets of the Plan, subject to such limitations as may be provided in the documents governing the relationship between or among the Plan, the Company (if applicable)
and the Trustee or Investment Manager. 
 9.13 Section 404(c) Provisions. 

(a) This Plan is intended to constitute a plan described in Section 404(c) of ERISA and the regulations thereunder. As a result, with
respect to elections described in the Plan and any other exercise of control by a Participant or Beneficiary over assets in the Participant’s Accounts, such Participant or Beneficiary shall be solely responsible for such actions, and neither
the Trustee, the Committee, the Company, nor any other person or entity which is otherwise a Fiduciary shall be liable for any loss or liability which results from such Participant’s or Beneficiary’s exercise of control. 

(b) The Committee shall provide to each Participant or his Beneficiary the information described in Section 2550.404(c)-1(b)(2)(i)(B)(1)
of the Department of Labor Regulations. Upon request by a Participant or his Beneficiary, the Committee shall provide the information described in Section 2550.404c-1(b)(2)(i)(B)(2) of the Department of Labor Regulations.

(a) It is the Company’s expectation that the Plan and the payment of contributions hereunder will be continued indefinitely, but
continuance of the Plan by the Company is not assumed as a contractual obligation, and the Company reserves the right to permanently discontinue contributions hereunder. In the event of the complete discontinuance of contributions by the Company,
the entire interest of each Participant affected thereby shall immediately become 100% vested. The Company, the Board of Directors, the Committee, and the Employees, agents and shareholders of the Company shall not be liable for the payment of any
benefits under the Plan and all benefits hereunder shall be payable solely from the assets of the Trust except as otherwise required by ERISA. 

(b) The Board of Directors may terminate the Plan at any time. Upon complete termination or partial termination of the Plan, the entire
interest of each of the affected Participants shall become 100% vested. The Trustee shall thereafter, upon direction of the Committee, distribute to the Participants the amounts in such Participant’s Accounts in the same manner as set forth in
Article VI, subject, where appropriate, to Section 403(d)(1) of ERISA and regulations of the Secretary of Labor thereunder as may affect allocation of assets upon termination of such Plan. 

  
 51 

 10.4 Failure to Contribute. The failure of the Company to contribute to the Trust in any
year, shall not, in and of itself, constitute a complete discontinuance of contributions to the Plan. 
 10.5 Merger or
Consolidation. 
 (a) This Plan and its related Trust shall not in whole or in part merge or consolidate with, or transfer its assets or
liabilities to any other plan or trust unless each affected Participant in this Plan would receive a benefit immediately after the merger, consolidation, or transfer (if the Plan then terminated) which is equal to or greater than the benefit he
would have been entitled to receive immediately before the merger, consolidation, or transfer (if the Plan had then terminated). 
 (b) In
the event of a consolidation, merger, sale, liquidation, or other transfer of the operating assets of the Company to any other company, the ultimate successor or successors to the business of the Company shall automatically be deemed to have elected
to continue this Plan in full force and effect, in the same manner as if the Plan had been adopted by resolution of its board of directors, unless the successor(s), by resolution of its board of directors, shall elect not to so continue this Plan in
effect, in which case the Plan shall automatically be deemed terminated as of the applicable effective date set forth in the board resolution. 

(c) The Committee may, in its discretion, authorize a plan-to-plan transfer, provided such transfer will meet the requirements of
Section 414(l) of the Code and that all other actions legally required are taken. In the event of a transfer of assets from the Plan pursuant to this subsection, any corresponding benefit liabilities shall also be transferred. 

(d) In the event that assets are transferred to this Plan from another qualified plan in a plan-to-plan transfer, such assets will be
accounted for separately to the extent required to preserve optional forms of benefit or other attributes of the transfer or plan as may be required by law or as may be determined by the Committee to be desirable. 

10.6 Procedures on Termination. 

(a) Upon termination of the Plan, the Committee shall determine whether to continue the Trust, to distribute the assets of the Trust to
Participants, Beneficiaries and Alternate Payees, to transfer the assets in the Trust to another qualified plan maintained by the Company, or to take other action consistent with applicable law. 

(b) The Trustee and the Committee shall continue to function as such for such period of time as may be necessary for the winding up of this
Plan and for the making of distributions in accordance with the provisions of this Plan. 

  
 52 

 10.7 Partial Termination. 

(a) In the event of a partial termination of the Plan within the meaning of Code Section 411(d)(3), the interest of affected Participants
in the Trust Fund, as of the date of the partial termination, shall become nonforfeitable as of that date. 
 (b) That portion of the assets
of the Plan affected by the partial termination shall be used exclusively for the benefit of the affected Participants and their Beneficiaries, and no part thereof shall otherwise be applied. 

(c) With respect to Plan assets and Participants affected by a partial termination, the Committee and the Trustee shall follow the same
procedures and take the same actions prescribed in this Article X in the case of a total termination of the Plan. 

  
 53 

 ARTICLE XI 

MISCELLANEOUS 
 11.1
Contributions Not Recoverable. Except where contributions are required to be returned to the Company by the provisions of the Plan as permitted or required by ERISA or the Code, it shall be impossible for any part of the contributions made under
the Plan to be used for, or diverted to, purposes other than the exclusive benefit of Participants or their Beneficiaries. Notwithstanding this or any other provision of the Plan, the Company shall be entitled to recover, and the Participants under
the Plan shall have no interest in (i) any contributions made under the Plan by mistake of fact, so long as the contribution is returned within one year after payment and (ii) any contributions for which deduction is disallowed under
Section 404 of the Code, so long as the contributions are returned to the Company within one year following such disallowance or as permitted or required by the Code or ERISA. In the event of such mistake of fact or disallowance of deductions,
contributions shall be returned to the Company, subject to the limitations, if any, of Section 403(c) of ERISA. 
 11.2 Limitation
on Participant’s Rights. Participation in the Plan shall not give any Employee the right to be retained as an Employee of the Company or any right or interest under the Plan other than as herein provided. The Company reserves the right to
dismiss any Employee without any liability for any claim either against the Trustee, the Trust except to the extent provided in the Trust, or against the Company. All benefits under the Plan shall be provided solely from the assets of the Trust.

 11.3 Receipt or Release. Any payment to any Participant or Beneficiary in accordance with the provisions of the Plan shall, to the
extent hereof, be in full satisfaction of all claims against the Trustee, the Committee and the Company. The Trustee may require such Participant or Beneficiary, as a condition precedent to such payment, to execute a receipt and release to such
effect. 
 11.4 Alienation. Except as otherwise provided by law and as otherwise provided by Sections 11.5 and 11.6: 

(a) The interest of any Participant, Beneficiary or Alternate Payee in the income, benefits, payments, claims or rights hereunder, or in the
Trust Fund shall not in any event be subject to sale, assignment, hypothecation, or transfer. Each Participant, Beneficiary or Alternate Payee is prohibited from anticipating, encumbering, assigning, or in any manner alienating his interest under
the Trust Fund, and is without power to do so, except as may otherwise be provided for in the Trust Agreement. The interest of any Participant, Beneficiary or Alternate Payee shall not be liable or subject to his debts, liabilities, or obligations,
now contracted, or which may be subsequently contracted. The interest of any Participant, Beneficiary or Alternate Payee shall be free from all claims, liabilities, bankruptcy proceedings, or other legal process now or hereafter incurred or arising;
and the interest or any part thereof, shall not be subject to any judgment rendered against the Participant, Beneficiary or Alternate Payee. 

  
 54 

 (b) In the event any person attempts to take any action contrary to this Article XI, that action
shall be void and the Company, the Committee, the Trustee and all Participants, their Beneficiaries and Alternate Payees may disregard that action and are not in any manner bound thereby, and they, and each of them separately, shall suffer no
liability for any disregard of that action, and shall be reimbursed on demand out of the Trust Fund for the amount of any loss, cost or expense incurred as a result of disregarding or of acting in disregard of that action. 

(c) The preceding provisions of this Section 11.4 shall be interpreted and applied by the Committee in accordance with the requirements
of Code Section 401(a)(13) as construed and interpreted by authoritative judicial and administrative rulings and regulations. 

11.5 Nonconforming Distributions Under Court Order. 

(a) The right to a benefit payable with respect to a Participant pursuant to a “qualified domestic relations order” (within the
meaning of Section 414(p) of the Code) may be created, assigned or recognized. The Committee shall establish reasonable procedures to determine the qualified status of domestic relations orders and to administer distributions under such
qualified orders. In the event a qualified domestic relations order exists with respect to a benefit payable under the Plan, the benefits otherwise payable to a Participant or Beneficiary shall be payable to the Alternate Payee specified in the
qualified domestic relations order. 
 (b) The Plan’s obligations to the Participant and each Alternate Payee shall be discharged to
the extent of any payment made pursuant to such qualified domestic relations order. 
 (c) The reasonable expense of determining whether a
domestic relations order satisfies the requirements of being a qualified domestic relations order shall be charged to the Account of the Participant; provided, however, that if a qualified domestic relations order so provides, such expense may,
instead, be charged to the Alternate Payee’s share of the Participant’s Account or divided equally between the Participant and the Alternate Payee. 

11.6 Authorized Participant Loans. 

(a) Each Participant shall have the right, subject to prior approval by the Committee, to borrow from his Accounts. Application for a loan
must be submitted by a Participant to the Committee according to the procedures established by the Committee. Approval shall be granted or denied in accordance with the rules established by the Committee to govern loans from the Plan, and the
Committee shall have the power to modify such rules. Such rules are included in a separate document(s) and shall be considered a part of the Plan; provided, each rule and each loan shall be made only in accordance with the regulations and rulings of
the Internal Revenue Service and Department of Labor and other applicable state or federal law. The Committee shall act in its sole discretion to ascertain whether the requirements of such regulations and rulings and the Plan loan rules have been
met. 
 (b) Notwithstanding anything contained in the rules established by the Committee pursuant to Section 11.6(a), each loan shall,
by its terms, satisfy each of the following requirements: 

  
 55 

 (i) The amount of the loan shall not exceed the lesser of: 

(1) $50,000, reduced by the excess, if any, of a Participant’s highest outstanding balance of all loans from the Plan during the
preceding 12 months over the outstanding balance of such loans on the loan date, or 
 (2) 50% of the value of the Participant’s
Vested Interest in his Accounts, except that a Participant’s Survivor Annuity Subaccount shall not be included in determining such value. For purposes of this Section 11.6(b), the Participant’s Vested Interest and outstanding loan
balances in all qualified employer plans (as such term is defined in Code Section 72(p)(4)) of the Company shall be aggregated to determine whether a loan shall be permissible hereunder and the maximum permissible amount thereof. 

(ii) Each loan must be repaid within sixty (60) months (except that if the loan proceeds are being used to purchase the principal
residence of a Participant, the Committee may, in its discretion, establish a term of up to 30 years for repayment). 
 (iii) Each loan
must require substantially level amortization over the term of the loan, with payments not less frequently than quarterly (loan payments may be suspended during a Participant’s active military service, as provided in Section 414(u)(4) of
the Code). 
 (iv) Each loan must be adequately secured, with the security to consist of the balance of the Participant’s Accounts
other than the Survivor Annuity Subaccount. For this purpose, the amount of the security must be at least equal to the amount of the loan. A Participant’s Survivor Annuity Subaccount shall not constitute security for any loan made after
January 1, 2006. 
 (1) In the case of any Participant who is an active Employee, automatic payroll deductions shall be required as
additional security. To the extent a Participant’s loan is secured by the Participant’s Accounts, the investment gain or loss attributable to the loan shall not be included in the calculation or allocation of the increase or decrease in
fair market value of the general assets of the Plan pursuant to Section 3.9. Instead, the entire gain or loss (including any gain or loss attributable to interest payments or default) shall be allocated to the Accounts of the Participant. 

(2) In the case of any other Participant, the outstanding loan balance may at no time exceed 50% of the outstanding vested balance of the
Participant’s Accounts; provided, however, that for any loan made after January 1, 2006, a Participant’s Survivor Annuity Subaccount shall not be included in a Participant’s Accounts for this purpose. If such limit is at any time
exceeded, or if the Participant fails to make timely repayment, the loan will be treated as in default and become immediately payable in full, subject to rules established by the Committee. 

(c) If the loan, or a loan from another qualified retirement plan maintained by the Company, is to be secured by some or all of the
Participant’s Survivor Annuity Subaccount under the Plan, the Participant and his spouse, if any, must consent to the loan and the possible reduction in the Survivor Annuity Subaccount in the event of a setoff of the loan against the

  
 56 

 
Survivor Annuity Subaccount balances as a result of nonpayment of the loan. Such consent must be given in writing within a ninety day period before the Committee makes the loan. In the event the
Participant defaults on the loan and Participant’s Survivor Annuity Subaccount is security for the loan, the Survivor Annuity Subaccount balances will not be used to satisfy the loan obligation prior to the earlier of the Participant’s
termination of employment with the Company or an event resulting in a permissible distribution of his Survivor Annuity Subaccount under the Plan. In the event of default, the Company shall offset the amount owed by the Participant against any
amounts owed by the Company to the Participant. 
 (d) In connection with the making of any loan to a Participant pursuant to the provisions
of this Section 11.6, the Participant receiving such a loan may be required to execute such documents as may be required by the Committee and/or Trustee. 

11.7 Lapsed Benefits. 

(a) In the event that a benefit is payable under this Plan to a Participant or Beneficiary and after reasonable efforts such individual cannot
be located for the purpose of paying the benefit after a reasonable time following the date payment would otherwise have been made, the benefit shall be forfeited and treated like other forfeitures pursuant to the provisions of Section 8.1. If
the Participant or Beneficiary later makes a valid claim for the benefit, the claim shall be paid pursuant to directions by the Committee. 

(b) For purposes of this Section 11.7, the term “Beneficiary” shall include any person entitled under Section 6.2 to
receive the interest of a deceased Participant or deceased designated Beneficiary and shall also include an Alternate Payee. The Committee or its delegate is authorized to accept assets representing benefits payable to the following individuals:
(i) the individual was a participant or beneficiary in a tax-qualified defined contribution plan, (ii) such plan has been terminated, (iii) at the time of the payment of benefits with respect to the termination of such plan, the
sponsor of the plan was an Affiliated Company, and (iv) payment of benefits cannot be made to such individual because such individual cannot be located or has failed to consent to distribution. Any such individual shall be considered a
“Beneficiary” solely for purposes of this Section 11.7. 
 (c) The Accounts of a Participant shall continue to be maintained
until the amounts in the Accounts are paid to the Participant or his Beneficiary. In the event that the Plan is terminated and the Committee directs the Trustee to liquidate the Trust and distribute the assets of the Trust Fund, the following rules
shall apply: 
 (i) All Participants and Beneficiaries (including Participants and Beneficiaries who have not previously claimed their
benefits under the Plan) shall be notified of their right to receive a distribution of their interests in the Plan. 
 (ii) All
Participants and Beneficiaries shall be given a reasonable length of time, which shall be specified in the notice, in which to claim their benefits. 

(iii) All Participants (and their Beneficiaries) who do not claim their benefits within the designated time period shall be presumed to be
dead. The Accounts of such Participants shall be forfeited at such time. These forfeitures shall be disposed of according to rules prescribed by the Committee, which rules shall be consistent with applicable law. 

  
 57 

 (iv) The Committee shall prescribe such rules as it may deem necessary or appropriate with
respect to the notice, deposit or forfeiture rules stated above. 
 (d) Should it be determined that the preceding rules relating to
forfeiture of benefits upon Plan termination are inconsistent with any of the provisions of the Code and/or ERISA, these provisions shall become inoperative without the need for a Plan amendment and the Committee shall prescribe rules that are
consistent with the applicable provisions of the Code and/or ERISA. 
 11.8 Addresses. Each Participant shall be responsible for
furnishing the Committee with his correct current address and the correct current name and address of his Beneficiary or Beneficiaries. 

11.9 Notices and Communications. 

(a) All applications, notices, designations, elections, and other communications (collectively referred to in this Section 11.9 as
“communications”) from or to Participants, Beneficiaries and Alternate Payees shall be made in the manner prescribed by the Committee. The Committee may require or permit to be made by means of such written or electronic media as the
Committee may prescribe. 
 (b) To the extent written communication is provided for by the Committee, an item shall be deemed to have been
delivered and received by the Participant, Beneficiary or Alternate Payee when it is deposited in the United States mail with postage prepaid, addressed to the Participant, Beneficiary or Alternate Payee at his last address of record with the
Committee. 
 (c) The Committee in its absolute discretion may accept or require communications given by facsimile, telex, telegram,
telephone or any form of electronic communication that the Committee reasonably believes in good faith to be genuine. If the Committee chooses to accept one or more alternative methods of communication, the Company, any Affiliated Company, any
Participant or Beneficiary or any other person providing communication to the Committee will be required to follow reasonable procedures adopted by the Committee for written confirmation. In addition, the Committee may record oral instructions. If
any person providing communication to the Committee fails or refuses to comply with the Committee’s confirmation procedures, the Committee will be entitled to refuse to comply with such communications without incurring any liability for such
refusal. 
 11.10 Governing Law. All legal questions pertaining to the Plan shall be determined in accordance with the provisions of
ERISA and, to the extent not preempted by ERISA, the laws of the Commonwealth of Virginia; provided, however, that if any provision is susceptible to more than one interpretation, such interpretation shall be given thereto as is consistent with the
Plan remaining qualified within the meaning of Section 401(a) of the Code. If any provisions of this instrument shall be held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions hereof shall continue to
be fully effective. All contributions made hereunder shall be deemed to have been made in Virginia. 

  
 58 

 11.11 Interpretation. Article and Section headings are for convenient reference only and

 11.12 Withholding For Taxes. Any payments out of the Trust Fund may be
subject to withholding for taxes as may be required by any applicable federal or state law. 
 11.13 Limitation on Company, Committee and
Trustee Liability. Any benefits payable under this Plan shall be paid or provided for solely from the Trust Fund and neither the Company, the Committee nor the Trustee assume any responsibility for the sufficiency of the assets of the Trust to
provide the benefits payable hereunder. 
 11.14 Successors and Assigns. This Plan and the Trust established hereunder shall inure to
the benefit of, and be binding upon, the parties hereto and their successors and assigns.

may be executed in any number of identical counterparts, each of which shall be deemed a complete original in itself and may be introduced in evidence or used for any other purpose without the production of any other counterparts. 

11.16 Top-Heavy Plan Requirements. 

(a) For any Plan Year for which the Plan is top-heavy, and despite any other provisions of the Plan to the contrary, the Plan will be subject
to the provisions of this Section 11.16. 
 (b) Criteria. The Plan shall be top-heavy for any Plan Year if any of the following
conditions exist: 
 (i) The Top-Heavy Ratio for the Plan exceeds 60% and the Plan is not part of any Required Aggregation Group or
Permissive Aggregation Group of Plans. 
 (ii) The Plan is part of a Required Aggregation Group of plans, but not part of a Permissive
Aggregation Group, and the Top-Heavy Ratio for the group of plans exceeds 60%. 
 (iii) The Plan is part of a Required Aggregation Group
and part of a Permissive Aggregation Group of plans and the Top-Heavy Ratio for the Permissive Aggregation Group exceeds 60%. 
 (c)
Definitions. As used in this Section 11.16, the following terms shall have the meanings specified below. 
 (i)
Determination Date: With respect to any Plan Year, (1) the Determination Date shall be the last day of the preceding Plan Year, or (2) in the case of the first Plan year of the Plan, the last day of such Plan Year. 

  
 59 

 (ii) Key Employee: Any Employee or former Employee (and the Beneficiaries of such
Employees) who, pursuant to the rules of Code Section 416(i) and the Regulations thereunder, is or was: 
 (1) An officer of the
Company having an annual Compensation greater than 50% of the dollar limitation under Code Section 415(b)(1)(A) (for Determination Dates on and after January 1, 2002, Compensation of greater than $130,000 (as adjusted under Code
Section 416(i)(1))); 
 (2) For Determination Dates on or before December 31, 2001, one of the ten Employees having annual
Compensation from the Company of more than the dollar limitation under Code Section 415(c)(1)(A), and owning (or considered as owning) under Code Section 318 the largest interest in the Company; 

(3) A 5% Owner of the Company; or 

(4) A 1% Owner of the Company having Annual Compensation from the Company of more than $150,000. 

The determination period is the Plan Year containing the Determination Date and the four preceding Plan Years. Effective January 1, 2002,
the five-year look-back period is reduced to a one-year period ending on the Determination Date, with the exception of any distribution made for a reason other than separation from service, death, or disability. 

(iii) Permissive Aggregation Group: The Required Aggregation Group of plans plus any other plan or plans of the Company that, when
considered as a group with the Required Aggregation Group, would continue to satisfy the requirements of Code Sections 401(a)(4) and 410, and which are designated by the Company to constitute a Permissive Aggregation Group. 

(iv) Required Aggregation Group: (1) Each plan of the Company in which a Key Employee is a Participant or was a Participant at
any time during the Plan Year containing the Determination Date or any of the four preceding Plan Years (regardless of whether the Plan has terminated) and (2) any other qualified plan of the Company that enables a plan described in (1) to
meet the requirements of Code Section 401(a)(4) or 410. 
 (v) Top Heavy Ratio: 

(1) If the Company maintains one or more defined contribution plans (including any Simplified Employee Pension) and the Company has not
maintained any defined benefit plan that during the five year period ending on the Determination Date has or has had accrued benefits, the Top Heavy Ratio for this Plan alone or for the Required Aggregation Group or Permissive Aggregation Group, as
appropriate, is a fraction, the numerator of which is the sum of the Account balances of Key Employees as of the Determination Date (including any part of any account balance distributed in the five year period ending on the Determination Date), and
the denominator of which is the sum of all account balances (including any part of any account balance distributed in the five year period ending on the Determination Date), both computed in accordance with Code Section 416 and regulations
thereunder. Both the numerator 

  
 60 

 
and denominator of the Top Heavy Ratio are adjusted to reflect any contributions not actually made as of the Determination Date, but which is to be taken into account on that date under Code
Section 416 and regulations thereunder. 
 (2) If the Company maintains one or more defined contribution plans (including any
Simplified Employee Pension) and the Company maintains or has maintained one or more defined benefit plans that during the five year period ending on the Determination Date has or has had any accrued benefits, the Top Heavy Ratio for any Required or
Permissive Aggregation Group, as appropriate, is a fraction, the numerator of which is the sum of Account balances under the aggregated defined contribution plan or plans for all Key Employees determined in accordance with (1) above and the
present value of accrued benefits under the aggregated defined benefit plan or plans for all Key Employees as of the Determination Date, and the denominator of which is the sum of the Account balances under the aggregated defined contribution plan
or plans for all Participants determined in accordance with (1) above, and the present value of accrued benefits under the defined benefit plan or plans for all Participants as of the Determination Date, all determined in accordance with Code
Section 416 and the regulations thereunder. The accrued benefits under a defined benefit plan in both the numerator and denominator of the Top Heavy Ratio are adjusted for any distribution of an accrued benefit made in the five year period
ending on the Determination Date. Solely for the purpose of determining if the Plan, or any other plan included in a Required Aggregation Group is top heavy (within the meaning of Code Section 416(g)), the accrued benefit of an Employee other
than a Key Employee shall be determined under (i) the method, if any, that uniformly applies for accrual purposes under all plans maintained by the Company and any Affiliated Companies or (ii) if there is no such method, as if such benefit
accrued not more rapidly than the slowest accrual rate permitted under the fractional accrual rate of Code Section 411(b)(1)(C). 

(3) For purposes of (1) and (2) above, the value of Account balances and the present value of accrued benefits will be determined
as of the most recent Valuation Date that falls within or ends with the twelve month period ending on the Determination Date, except as provided in Code Section 416 and regulations thereunder for the first and second Plan Years of a defined
benefit plan. The Account balances and accrued benefits of a Participant (A) who is not a Key Employee but who was a Key Employee in a prior year or (B) who has not been credited with at least one Hour of Service with any Company
maintaining the Plan at any time during the five year period ending on the Determination Date will be disregarded. The calculation of the Top Heavy Ratio, and the extent to which distributions, rollovers and transfers are taken into account, will be
made in accordance with Code Section 416 and regulations thereunder. Voluntary deductible contributions will not be taken into account in computing the Top Heavy Ratio. When aggregating plans, the value of account balances and accrued benefits
will be calculated with reference to the Determination Dates that fall within the same calendar year. 
 (4) For purposes of establishing
the present value in order to compute the Top Heavy Ratio any benefit shall be discounted only for mortality and interest based on the interest rate that would be used as of the date of distribution by the Pension Benefit Guaranty Corporation to
determine the present value of a lump sum distribution on plan termination. 

  
 61 

 (vi) Valuation Date: The date as of which Account balances or accrued benefits are valued
for purposes of calculating the Top Heavy Ratio. 
 (d) Vesting Requirements. If the Plan is determined to be a top-heavy plan in any
Plan Year, then a Participant’s rights to his Accounts derived from Company Contributions, determined as of the end of such Plan Year, shall vest in accordance with the following schedule, unless a more rapid vesting schedule is then in effect
under the terms of the Plan: 
  

						
	 Years of Vesting Service
	  	Vesting Percentage
	 2
	  	 	 	20	%
	 3
	  	 	 	40	%
	 4
	  	 	 	60	%
	 5
	  	 	 	80	%
	 6 or more
	  	 	 	100	%

 If the Plan ceases to be a top-heavy plan in any Plan Year, then the vesting schedule set forth in
Section 5.2 shall apply for such Plan Year with respect to any portion of a Participant’s Accounts that is forfeitable as of the beginning of such Plan Year; provided, however, that a Participant with three or more Years of Service shall
be given the option of remaining under the vesting schedule set forth above. 
 (e) Minimum Contribution. If this Plan is top heavy
in any Plan Year, the Company Contributions for such year for each “participant” (as defined for the purpose of providing mandatory minimum contributions under regulations) who is not a Key Employee shall not be less than three percent
(3%) of such participant’s compensation. If, however, the Plan does not enable a defined benefit plan to meet the requirements of Section 401(a)(4) or 410, the Company Contributions shall not exceed that percentage of each
participant’s compensation which is equal to the highest percentage of compensation at which Company Contributions are made for the Plan Year for any Key Employee (1) under the Plan or (2) if the Plan is part of an aggregation group,
under any defined contribution plan in such group. For Plan Years beginning before January 1, 1989, for purposes of this Section 11.16(e), Company Contributions attributable to a salary reduction or similar arrangement and contributions
made pursuant to Chapter 21 of Title II of the Social Security Act shall be disregarded. For Plan Years beginning after December 31, 1988, Company Contributions attributable to a salary reduction or similar arrangement made by Employees other
than Key Employees shall not be taken into account under this Section 11.16(e). Effective January 1, 2002, Company Matching Contributions shall be taken into account in determining whether the minimum contribution requirement has been
satisfied under Code Section 416(c)(2). Company Matching Contributions that are used to satisfy the minimum contribution requirements shall be treated as matching contributions for purposes of the average contribution percentage test and other
requirements of Section 401(m) of the Code. 
 11.17 Rule 16b-3 Provisions. The Committee may (but need not) adopt such rules
and/or take such actions or implement such measures and/or limitations as it deems desirable in order to comply with 17 C.F.R. 140.16b-3, promulgated under Section 16 of the Securities Exchange Act of 1934, as amended (the “SEC
Section 16”). Neither the Company, the Board of 

  
 62 

 
Directors, the Committee, the Trustee nor the Plan shall have any liability to any Participant in the event that any Participant has any liability under SEC Section 16 due to any rule so
adopted, the failure to adopt any rule, any Plan provision (or lack thereof), and transaction in the Plan or otherwise. 
 11.18 Military
Service. Notwithstanding any provision of the Plan to the contrary, contributions, benefits and service credit with respect to qualified military service shall be provided in accordance with Section 414(u) of the Code. 

11.19 Errors, Misstatements, and Payment of Interest. In the event of any misstatement, error, or omission of fact resulting in payment
of benefits in an incorrect amount, the Committee shall promptly cause the amount of future payments to be corrected upon discovery of the facts, and shall pay, or authorize others to pay, the Participant or his Beneficiary any underpayment, in cash
in a lump sum, or to recoup, or authorize others to proceed against the Participant or his Beneficiary for recovery of any such overpayment. Except as otherwise specifically provided herein, no interest or investment earnings shall be paid on the
payment of any corrected amounts.

 ARTICLE XII 

ESOP FEATURE 
 12.1
ESOP Contributions. 
 (a) ESOP Establishment. This Article XII adds an ESOP Feature to the Plan, which ESOP Feature is both a
stock bonus plan and an employee stock ownership plan intended to qualify under Sections 401(a) and 4975(e)(7) of the Code, and as such is designed to invest primarily in employer securities described in Section 409(l) of the Code. The ESOP
Feature shall become effective (“ESOP Effective Date”) as of September 27, 2013. Up to 100% of the assets of the ESOP Fund shall be invested in Company Stock. An ESOP Contribution is any contribution to the Plan which the Company
designates as such. ESOP Contributions shall be wholly invested in Company Stock, unless otherwise directed by the Company and except as provided otherwise due to an election under Section 12.2. 

(b) Character of the Fund. The Company has provided for the establishment of the Company Stock Fund under the provisions of this
Section 12.1 and other applicable provisions of the Plan with the intent that the Company Stock Fund, as distinguished from the investment alternatives established and maintained in the discretion of the Committee, constitute an employee stock
ownership plan (ESOP) or fund, thereby qualifying the Plan as an “eligible individual account plan” as defined in Section 407(d)(3) of ERISA (“EIAP”). Pursuant to Section 404(b) of ERISA (which applies equally to all
EIAPs, whether or not the ESOP component contains the additional provisions required in order to leverage the acquisition of employer stock or enjoy the benefit of certain special tax incentives), the Plan is exempt from, and the Company Stock Fund
shall accordingly be maintained and administered without regard to (i) the general prohibition against investment of more than ten percent of plan assets in employer securities and (ii) the diversification requirement and prudence
requirement to the extent that it requires diversification of Section 404(a)(1) of ERISA. Consequently, and in furtherance of such intent and the policy underlying the special treatment of such ESOPs and EIAPs under Section 404(b) of ERISA
(including the perceived desirability of giving employees an ownership stake in the Company, with the attendant potential benefits as well as the risks), the Company Stock Fund shall at all times be invested exclusively in Company Stock except for
such reserve invested in short-term fixed income investments or cash as shall be determined to be necessary or advisable for the purpose of maintaining appropriate liquidity in order to satisfy daily Participant exchange, transfer, withdrawal or
distribution requests, as more fully provided in the Trust. 
 12.2 Diversification Election. 

(a) Notwithstanding any other provision of the Plan following the ESOP Effective Date, any Participant who has attained age 55 and completed
at least ten (10) years of participation in the Plan (a “Qualified Participant”) may elect to have up to 25% of the value in his ESOP Account invested in the funds referred to in Section 12.2(b). Any such Participant may make
this election at least once during each Plan Year of his Qualified Election Period. During the sixth Plan Year in the Participant’s Qualified Election Period, the Participant may so direct the investment of up to 50% of the value of amounts in
his ESOP Account. For this 

  
 64 

 
purpose, the term “Qualified Election Period” shall mean the period beginning with the Plan Year in which the Participant becomes a Qualified Participant and ending upon the earlier of
the Participant’s Termination of Employment or the sixth Plan Year following diversification eligibility. The percentage of amounts in a Participant’s ESOP Account for which he may make investment directions in a Plan Year shall be the
“Allocable Portion” of such Participant’s Account at the time of the election under this Section 12.2. 
 (b) A
Participant may elect to have the dollar value of the Allocable Portion of his ESOP Account, on the Valuation Date following the date on which the election is filed, invested by the Trustee in any investments available under the Plan (other than
Company Stock) which are maintained by the Trustee and which conform to the requirements of Code Section 401(a)(28)(B). Such election, which shall be made pursuant to procedures established by the Committee, shall be in accordance with any
notice, rulings, or regulations or other guidance issued by the Internal Revenue Service with respect to Code Section 401(a)(28)(B). Once such election is made, the Participant cannot subsequently direct that such Allocable Portion (or any
income thereon) be re-invested in any portion of the ESOP Fund. 
 12.3 Dividends on Allocated Shares. As of and after the ESOP
Effective Date, all cash dividends on Company Stock allocated to Participants’, Beneficiaries’ and Alternate Payees’ Accounts may, as determined by the Company consistent with Section 404(k) of the Code, be retained in the
Participants,’ Beneficiaries’ and Alternate Payees’ Accounts, or be paid out to the Participant, Beneficiary or Alternate Payee. The Committee may determine how such dividends may be applied for any Plan Year up to the time when such
dividends are finally allocated to the Accounts of Participants as of the last day of the Plan Year. 
 12.4 Valuation of Stock.
Company Stock held in Participants,’ Beneficiaries’ and Alternate Payees’ Accounts shall be valued pursuant to Section 3.9(c). 

12.5 Tender for Stock. All tender or exchange decisions with respect to Company Stock held by the Trustee shall be made only by
Participants, Beneficiaries and Alternate Payees acting in their capacity as Named Fiduciaries with respect to both allocated and unallocated Shares in accordance with the provisions of Section 9.9(b). 

12.6 Voting of Stock. All voting rights on Company Stock held by the Trustee shall be exercised by the Trustee in accordance with the
provisions of Section 9.9(a). 
 12.7 Put Right. If, at the time of distribution, Company Stock distributed from the ESOP Fund
is not readily tradable on an established market within the meaning of Section 409(h) of the Code and the Treasury Regulations thereunder, such Company Stock shall be subject to a put right in the hands of a Qualified Holder by which such
Qualified Holder may sell all or any part of the Stock distributed to him by the ESOP Fund to the Trustee. For this purpose, the determination of whether such Company Stock is readily tradable on an established market shall be made consistent with
the rules set forth in Section 3.9(c). Should the Trustee decline to purchase all or any part of the Company Stock put to it by the Qualified Holder, the Company shall purchase the Company Stock that the Trustee declines to purchase. The put
right shall be subject to the following conditions: 

  
 65 

 (a) The term ‘Qualified Holder’ shall mean the Participant, Beneficiary or Alternate
Payee receiving the distribution of such Company Stock, any other party to whom the Company Stock is transferred by gift or by reason of death, and also any trustee of an individual retirement account (as defined under Code Section 408) to
which all or any portion of the distributed Company Stock is transferred pursuant to a tax-free ‘rollover’ transaction satisfying the requirements of Sections 402 and 408 of the Code. 

(b) During the 60-day period following any distribution of such Company Stock, a Qualified Holder shall have the right to require the Company
to purchase all or a portion of the distributed Company Stock held by the Qualified Holder. The purchase price to be paid for any such Stock shall be their fair market value determined (1) as of the Valuation Date coinciding with or next
preceding the exercise of the put right under this Section 12.7 or, (2) in the case of a transaction between the Plan and a ‘disqualified person’ within the meaning of Section 4975(e)(2) of the Code or a ‘party in
interest’ within the meaning of Section 3(14) of ERISA, as of the date of the transaction. 
 (c) If a Qualified Holder shall fail
to exercise his put right under Section 12.7(b), the option right shall temporarily lapse upon the expiration of the 60-day period. As soon as practicable following the later of (1) the last day of the Plan Year in which the 60-day option
period began, or (2) the expiration of the 60-day period, the Company shall notify the non-electing Qualified Holder (if he is then a shareholder of record) of the valuation of the Company Stock as of that date. During the 60-day period
following receipt of such valuation notice, the Qualified Holder shall again have the right to require the Company to purchase all or any portion of the distributed Company Stock. The purchase price to be paid therefor shall be fair market value
determined (1) as of the Valuation Date coinciding with or next preceding the exercise of the put right under this Section 12.7(c) or, (2) in the case of a transaction between the Plan and a ‘disqualified person’ within the
meaning of Section 4975(e)(2) of the Code or a ‘party in interest’ within the meaning of Section 3(14) of ERISA, as of the date of the transaction. 

(d) The foregoing put rights under Sections 12.7(b) and (c) hereof shall be effective solely against the Company and shall not obligate
the Plan or Trust in any manner. 
 (e) In making the determination of fair market value, the Company shall apply the rules set forth in
Section 3.9(c). 
 (f) The period during which the put right is exercisable does not include any time when a Qualified Holder is unable
to exercise it because the Company is prohibited from honoring it by applicable Federal or State laws. 
 (g) Except as otherwise required
or permitted by the Code, the put rights under this Section 12.7 shall satisfy the requirements of Sections 54.4975-7(b) and 54.4975-11(a)(7)(i) of the Treasury Regulations to the extent, if any, that such requirements apply to such put rights.
Accordingly, the protections and rights described in this Section 12.7 are nonterminable. If the Trust holds or distributes Company Stock and the ESOP Feature is terminated, the protections and rights described in this Section 12.7 shall
continue to exist. In addition, except as required by Code Section 409(h) and by Treasury Regulation Sections 54.4975-7(b)(9), (10), or as otherwise required by applicable law, no Company Stock may be

  
 66 

 
subject to a put, call or other option, or buy-sell or similar arrangement while held by, and when distributed from, the Plan, whether or not the Plan is an employee stock ownership plan, within
the meaning of Code Section 4975(e)(7), at that time. Furthermore, the Plan shall not otherwise obligate itself to acquire Company Stock from a particular Qualified Holder at an indefinite time determined upon the happening of an event such as
the death of the Qualified Holder. 
 (h) Unless otherwise expressly provided by the Committee, a Qualified Holder must exercise his put
right in writing. If a Qualified Holder exercises his put right under this Section 12.7, payment for the Company Stock repurchased shall be made, in the case of a distribution of a Participant’s Account within one taxable year, in
substantially equal annual payments over a period beginning not later than 30 days after the exercise of the put right and not exceeding five years (provided that adequate security and reasonable interest are provided with respect to unpaid amounts)
or, in the case of other distributions, not later than 30 days after such exercise.

the time of such termination, unless otherwise specified in any subsequent amendment. 

  
 73 

 “Elective Deferrals” shall mean contributions paid over by the Company to the
Trustee at the election of a Participant in lieu of cash Compensation pursuant to Section 3.1. Except as otherwise provided in the following sentence, no amount that was designated or treated at the time of deferral or contribution as a
Catch-Up Contribution shall be treated as an Elective Deferral. If a Participant’s Elective Deferrals for a Plan Year are less than both the dollar limitation of Code Section 402(g) and the percentage limitation of Plan

applicable officer specified below) hours credited to an Employee for service with a predecessor employer provided that such service has been approved by the President, Chief Operating Officer or Executive Vice President for Human Resources of the
Company for recognition under this Plan, which approval shall apply on a nondiscriminatory basis to all Employees with service during the recognition period for such predecessor employer as calculated according to Committee rules.

period equivalency method set forth on Department of Labor Regulation Section 2530.200-3(e)(iii). Thus, regardless of the actual hours worked by such an Employee, the Employee shall be credited (as applicable) with either 45 Hours of Service
for any week in which the Employee would otherwise be required to be credited with at least one Hour of Service (90 hours for each two-week payroll period), or 95 Hours of Service for any semi-monthly payroll period in which the Employee would
otherwise be required to be credited with at least one Hour of Service. Employees not classified by the Company as exempt under wage and hour law shall not be subject to this subsection (a)(vi). 

(b) Hours of Service under subsections (a)(ii), (a)(iii), and (a)(iv) shall be calculated in accordance with Department of Labor Regulation 29
C.F.R. Section 2530.200b 2(b). Hours of Service shall be credited to the appropriate computation period according to the Department of Labor Regulation 29 C.F.R. Section 2530.200b 2(c). 

(c) In the event that an Employee receives credit for Hours of Service for a period during which no duties are performed (including sick
leave, jury duty, vacations or other paid non-work periods), the Employee shall be deemed to have completed Hours of Service for each day or portion thereof during that period on the basis of what he would have been credited if he had worked his
normal work schedule during such non-work period. 
 (d) To the extent not otherwise credited under this definition, Hours of Service
determined with respect to a Maternity or Paternity Absence shall be credited as follows: the Employee shall be credited (solely for purposes of determining whether a Break in Service has occurred) with those Hours of Service that otherwise would
normally have been credited to such Employee but for such absence, except that (i) the total number of Hours of Service so credited shall not exceed 426 and (ii) such Hours of Service shall be credited as Hours of Service in the Plan Year
in which the absence from work commences only if the Employee would be prevented from incurring a Break in Service in such Plan Year solely by virtue of such crediting, and shall otherwise be credited in the Plan Year immediately following the Plan
Year in which the absence from work commences.

application of the provisions of the Plan to Employees who are employed by the Company in the Commonwealth of Puerto Rico, and who are bona-fide residents of the Commonwealth of Puerto Rico or perform labor or services primarily within the
Commonwealth of Puerto Rico, regardless of residence for other purposes (“Puerto Rico Employees”). 
 (a) For Puerto Rico income
tax purposes, effective January 1, 2011, the Plan is intended to be a profit sharing plan with a cash-or-deferred arrangement qualified under the provisions of Sections 1081.01 (a) and (d) of the Internal Revenue Code for a New Puerto
Rico of 2011, as amended from time to time (the “2011 PR Code”), and any regulations issued by the Puerto Rico Treasury Department. The Trust Fund is intended to be exempt from Puerto Rico taxation under 2011 PR Code
Section 1081.01(a). 
 (b) Highly Compensated Employee. Notwithstanding Section 13.1, for Puerto Rico tax purposes, effective
January 1, 2011, a “Highly Compensated Employee” means a Puerto Rico Employee who: 
 (i) is an officer (as defined by
applicable regulations) of the Company; or 
 (ii) was a 5% Owner at any time during the calendar year ending with or within the Plan Year
or the preceding calendar year ending with or within the Plan Year; or 

  
 84 

 (iii) for the preceding calendar year, had Compensation from the Company in excess of the
maximum dollar amount in effect under 2011 PR Code Section 1081.01(d)(3)(E)(iii)(IV) (e.g., $110,000 in 2011, $115,000 in 2012 and 2013). 

For Puerto Rico tax purposes, the term “Highly Compensated Employee” also includes any former Puerto Rico Participant who has had a
termination of employment (or has had a deemed termination of employment) prior to the Plan Year, does not perform an Hour of Service for the Company during the Plan Year, and was a Highly Compensated Employee for the year of termination. 

For purposes of this Section 14.1(b), a “5% Owner” means a 5% Owner of the Company or an Affiliated Company. To determine if a
Puerto Rico Employee owns more than five percent (5%) of the shares, capital or profit of the Company or Affiliated Company, the controlled group rules, as defined by 2011 PR Code Section 1010.04, related entities rules, as defined by 2011
PR Code Section 1010.05 and affiliated service group rules, as defined by 2011 PR Code Section 1081.01(a)(14)(B) will be taken into account. 

(c) For purposes of this Article XIV, a “‘Puerto Rico Participant” shall mean a Puerto Rico Employee who is an Eligible
Employee and who has become a Participant in the Plan pursuant to Section 2.2. 
 (d) The following shall apply in lieu of the first
sentence of Section 3.1(a) hereof: Effective January 1, 2011, subject to the limitations of this Article III and Article IV, each Puerto Rico Participant may elect to defer up to seventy-five percent (75%) of his Compensation on a
pre-tax basis for a Plan Year, not to exceed the maximum dollar limit in effect under 2011 PR Code Section 1081.01(d)(7)(A)(ii) in any calendar year (e.g., $16,500 in 2011, $17,000 in 2012, and $17,500 in 2013). Notwithstanding the foregoing,
effective January 1, 2011, Elective Deferrals by a Puerto Rico Participant who also makes contributions to an individual retirement account described in 2011 PR Code Section 1081.02 cannot exceed the sum of the limits permitted under PR
Code Section 1081.01(d)(7)(A)(i) and PR Code Section 1081.02. In the event the Puerto Rico Participant participates in two or more plans, those plans shall be treated as one for purposes of the limit provided in PR Code
Section 1081.01(d)(7)(A). In the event that any limit in this Section is exceeded, the Committee shall, in its discretion, and to the extent permitted by ERISA, refund any excess Elective Deferrals in accordance with 2011 PR Code
Section 1081.01 and the regulations issued thereunder. 
 (e) Notwithstanding Section 3.1 to the contrary, effective
January 1, 2011, Puerto Rico Participants shall be eligible to make Catch-Up Contributions in accordance with, and subject to the limitations of, 2011 PR Code Section 1081.01(d)(7)(C) (e.g., $1,000 in 2011 and $1,500 in 2012). 

(f) In addition to the actual deferral percentage test set forth in Section 3.1(e) effective January 1, 2011, an actual deferral
percentage test in compliance with 2011 PR Code Section 1081.01(d)(3) and applicable regulations shall be applied separately with respect to Puerto Rico Participants on a current Plan Year basis. For purposes of applying the actual deferral
percentage test to Puerto Rico Participants, the definition of Highly Compensated Employee contained in subparagraph (b) hereof shall be used, and in the event of a failure of the 

  
 85 

 
test, the Committee shall in its discretion take such measures consistent with 2011 PR Code Section 1081.01 to correct such failure including without limitation (i) the distribution of
excess contributions, to the extent permitted by the 2011 PR Code and ERISA and (ii) the allocation of qualified nonelective contributions. 

(g) Notwithstanding any provision of the Plan to the contrary, effective January 1, 2012, a Puerto Rico Participant’s Compensation

in 2013). For purposes of this Section 14.1(h), all Puerto Rico tax qualified defined contribution plans maintained by the Company shall be treated as one defined contribution plan. 

(i) Effective, January 1, 2011, any contribution made by the Company on account of military service in accordance with Section 11.18
and Code Section 414(u) shall be made regardless of whether or not it is otherwise deductible in whole or in part in any taxable year under applicable provisions of the Uniformed Services Employment and Reemployment Rights Act and the 2011 PR
Code. Any contribution made to a Puerto Rico Participant pursuant to Section 11.18 which is also subject to this Section 14.1(i) shall be subject to the 2011 PR Code’s limitations on contributions under 2011 PR Code Sections
1081.01(a)(11), 1081.01(a)(12) and 1081.01(d)(7) for the year in which the military contribution under Code Section 414(u) could have been made, but for the military service, not the actual year of contribution. 

(j) Effective for Plan Years beginning on or after January 1, 2012, for purposes of the qualification requirements and the
non-discrimination and coverage testing provisions of 2011 PR Code Sections 1081.01(a) and 1081.01(d), the term “Affiliated Company” means an entity described in 2011 PR Code Section 1081.01(a)(14)(A) with Employees in the

periods during which such entity is so a member of a controlled group or under common control. 
 (k) For purposes of Hardship Withdrawal
under Section 6.3(b), an “immediate and heavy financial need” of a Puerto Rico Participant may only consist of:

 86 

 (ii) the purchase of the Puerto Rico Participant’s principal residence (not including

(l) Notwithstanding anything in the Plan to the contrary, a Puerto Rico Participant who makes a withdrawal on account of a financial hardship
under Sections 6.3(b) and 14.1(k) shall not be permitted to make Elective Deferrals under the Plan (or under any other plan maintained by the Company) during the twelve (12)-month period beginning on the date of the withdrawal. In addition, in the
calendar year following the date of the hardship withdrawal, the Puerto Rico Participant shall not be permitted to make Elective Deferrals which, when added to his Elective Deferrals during the calendar year of the withdrawal, exceed the dollar
limitation specified in 2011 PR Code Section 1081.01(d)(7)(A). 
 (m) Notwithstanding any provision of the Plan to the contrary, a
rollover to the Plan by a Puerto Rico Participant is limited to those eligible rollover distributions under Section 3.6 that are paid from a qualified trust that is described in both Code Section 401(a) and 2011 PR Code
Section 1081.01(a) or in 2011 PR Code Section 1081.01(a). 
 (n) Notwithstanding any provision of the Plan to the contrary, a
Puerto Rico Participant may elect, at the time and in the manner prescribed by the Committee, to have all or part of a distribution received from the Plan on account of termination of employment or the termination of the Plan paid directly in a
direct rollover to a “Puerto Rico eligible retirement plan” (as defined in below) that accepts the Puerto Rico Participant’s eligible rollover distribution. For purposes of this Section, the term “Puerto Rico eligible retirement
plan” means a qualified trust described in 2011 PR Code Section 1081.01(a) or an individual retirement account or annuity described in 2011 PR Code Sections 1081.02(a) and (b), respectively, that accepts the Puerto Rico Participant’s
eligible rollover distribution. Notwithstanding the foregoing, in order for such rollover distribution not to be subject to applicable U.S. and Puerto Rico income tax withholdings and to defer taxation under both the Code and the 2011 PR Code, as
applicable, a Puerto Rico Participant’s benefit must be distributed in the form of a direct rollover distribution to a plan that is tax qualified under both Code Section 401(a) and 2011 PR Code Section 1081.01(a). For Puerto Rico
Participants, the term “eligible rollover distribution” means all or any portion of a total distribution on account of separation from service of the total balance to the credit of the distributee.

 (o) Puerto Rico Participants shall not be eligible to make Roth Elective Deferrals or Roth
Rollover Contributions. 
 (p) Each contribution made by the Company to the Plan with respect to a Puerto Rico Participant is expressly
conditioned on the deductibility of such contribution under the 2011 PR Code, for the taxable year for which it is contributed. If the Puerto Rico Department of the Treasury disallows the deduction, or if the contribution was made by a mistake of
fact, to the extent permissible under ERISA, such contributions shall be returned to the Company within one (1) year after the disallowance of the deduction (to the extent disallowed), or after the payment of the contribution, respectively.

 (q) Contributions to the Plan by the Company with respect to the Puerto Rico Participants shall be paid to the Trustee not later than the
due date for filing the Company’s Puerto Rico income tax return for the taxable year in which such payroll period falls, including any extension thereof. 

(r) Any merger or consolidation of the Plan with, or transfer in whole or in part of the assets and liabilities of the Trust Fund to another
trust as applied to a Puerto Rico Participant under the Plan will be limited to the extent such other plan and trust are qualified under 2011 PR Code Section 1081.01(a). 

(s) Effective on and after January 1, 2012, loans to Puerto Rico Participants must meet the requirements of Section 11.6 and 2011 PR
Code Section 1081.01(b)(3)(E). 
 (t) Puerto Rico Participants shall not be subject to the top heavy requirements established in
Section 11.16 of the Plan. 
 (u) With respect to the Puerto Rico Participants, the Plan will be administered, governed and construed
according to the 2011 PR Code, where such law is not in conflict with applicable United States federal law.

 15.2 Transfer of Leidos Accounts. 

The portion of the Leidos Plan Trust attributable to Leidos Accounts shall be transferred to the Trustee on the Effective Date or as soon as

additional trustee under this Plan, until such transfer is completed. 
 15.3 Eligibility to Participate. 

An Eligible Employee who was a participant in the Leidos Plan on September 27, 2013 shall become a Participant on September 27,
2013, provided he remains an Eligible Employee. Notwithstanding the foregoing, any such individual who has made a hardship withdrawal of elective deferrals from the Leidos Plan within six months before the date of such initial eligibility shall not
be entitled to make Elective Deferrals under this Plan until six months have elapsed from the date of such hardship withdrawal. 
 15.4

this Plan. 
 15.7 Investment of Transferred Accounts. 

Funds transferred to the Trustee in respect of an Employee’s Leidos Account pursuant to Section 15.2 shall initially be invested in
accordance with Section 15.8 and shall remain so invested until the end of the blackout period established in connection with the spinoff of this Plan from the Leidos Plan. Thereafter, the Participant may change such investments incident to a
change made in the investment of his Account in accordance with Section 3.8 of the Plan.
