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 Plan Administrator may specify which in any event shall not be less frequent than once each
month. The Plan Administrator may provide that future contributions may be invested in a different investment alternative than amounts already accumulated in the Participant’s Account(s). 
 (e) The Plan Administrator 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. 
 (f)
The Plan Administrator shall provide notice by arranging for reports to Participants regarding the investment of their funds pursuant to their investment elections. Failure of a Participant to notify the Plan Administrator regarding implementation
of his investment election within thirty (30) days following 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 Plan Administrator 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 

  

 23 

 
if that method differs from the Participant’s election form or investment instructions. 
 4.7 Irrevocability. The Company shall have no right or title to, nor interest in, the contributions made to the Trust Fund, and no part of
the Trust Fund shall revert to the Company except that funds may be returned to the Company as follows: 
 (a) In the case of
a Company Contribution which is made by a mistake of fact, that contribution shall be returned to the Company within one (1) year after such contribution is made. 
 (b) If the Commissioner of the Internal Revenue Service determines that the Plan is not initially qualified under the Code, any
contribution made incident to that initial qualification by the Company shall be returned to the Company within one year after the date the initial qualification is denied, but only if the application for the qualification is made by the time
prescribed by law for filing the Company’s return for the taxable year in which the Plan is adopted, or such later date as the Secretary of the Treasury may prescribe. 
 (c) All Company Contributions to the Plan are conditioned upon the deductibility of those contributions under Code section 404. To
the extent a deduction is disallowed, the contribution shall, at the election of the Company, be returned to the Company within one year after the disallowance. 
 4.8 Company, Plan Administrator and Trustee Not Responsible for Adequacy of Trust Fund. 
 (a) Neither the Company nor the Trustee shall be liable or responsible for the adequacy of the Trust Fund to meet and discharge any or all payments and liabilities hereunder. All Plan benefits will be paid from the
Trust assets, and neither the Company nor the Trustee shall have any duty or liability to furnish the Trust with any funds, securities or other assets except as expressly provided in the Plan. 
 (b) Except as required under the Plan or Trust or under Part 4 of Title I of ERISA, the Company shall not be responsible for any
decision, act or omission of the Trustee or the Investment Manager (if applicable), and shall not be responsible for the application of any moneys, securities, investments or other property paid or delivered to the Trustee. 
 (c) The Company expressly disavows any contractual obligation, implied or explicit, to make any contribution to the Plan or to contribute
any specified amount. 
  

 24 

 4.9 Company Stock Transactions with Disqualified Persons. Acquisition or sale by the Plan
of Company Stock or other qualifying employer securities (as defined in ERISA section 407(a)(5)), from or to a “disqualified person” (as defined in Code section 4975(e)(2)), shall be at a price which represents “adequate
consideration” (as defined in ERISA section 3(18)) or, in the event such Company Stock or other qualifying employer security is a marketable obligation (as defined in ERISA section 407(e)), at a price not less favorable to
the Plan than the price determined under ERISA section 407(e)(1). 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 4.9 shall be made by the Plan Administrator. 
  

 25 

 ARTICLE V 
 ELECTIVE DEFERRALS, ROLLOVER CONTRIBUTIONS, 
 PLAN-TO-PLAN TRANSFERS AND VOLUNTARY CONTRIBUTIONS

 5.1 Election. At dates established by the Plan Administrator, each Participant may elect, on forms prescribed by the
Plan Administrator, to defer the receipt of a portion of his Compensation for that Plan Year and to have the deferred amount contributed directly by the Company to the Trust Fund as Elective Deferrals. 
 5.2 Amount Subject to Election; Nondiscrimination Requirement and Distribution of Excess Contributions. 
 (a) The amount of an individual’s Compensation that may be deferred subject to the election provided in Section 5.1 shall be a
percentage of the individual’s Compensation, not to exceed the maximum percentage established by the Plan Administrator, except with respect to Participants who formerly participated in the NNS 401(k) Plan and whose accounts in that plan are
transferred to the Plan pursuant to Section 5.6. With regard to such Participants who formerly participated in the NNS 401(k) Plan, the amount of such employees’ Compensation that may be deferred, subject to the election provided in
Section 5.1, shall be an amount equal to not less than one percent (1%) or such percentage of Compensation greater than 12 percent (12%) as may be specified from time to time by the Plan Administrator, provided that the percentage
rate for determining such contributions shall be a whole number. 
 (b) For purposes of Section 5.2(a), (i) the
amount of the individual’s Compensation shall be determined prior to the reduction caused by the deferral (if any) of a portion of his Compensation pursuant to this Article V and (ii) Compensation shall not include bonuses, income
from stock options, vesting stock or non-cash remuneration. 
 (c) The maximum amount of Elective Deferrals contributed on
behalf of a Participant under the Plan shall not exceed $7,000 (multiplied by the Adjustment Factor) during any calendar year. If a Participant’s Elective Deferrals to this Plan exceed the limitation described in the preceding sentence, the
Excess Deferral may be distributed to such Participant as Permitted by Code section 402(g)(A)(ii). Effective for Plan Years beginning on and after January 1, 1992, if, during a calendar year, (i) the Employee participates in this Plan and
one or more other plans with a qualified cash or deferred arrangement described in Code sections 401(k), 408(k)(6), 125 or 403(b), 

  

 26 

 
(ii) the Employee’s Elective Deferrals under all such plans (including this Plan) exceed $7,000 (multiplied by the Adjustment Factor), and
(iii) all or any portion of such Employee’s Elective Deferrals under this Plan constitute Excess Deferrals by virtue of an allocation and notification by the Employee pursuant to Code section 402(g)(2)(A)(i), such Excess Deferrals
shall not be distributed to such Employee as permitted by Code section 402(g)(2)(A)(ii), notwithstanding that the Employee may request such distribution, but rather shall be held in the Trust Fund in the same manner as such Employee’s
Elective Deferrals which do not constitute Excess Deferrals. 
 (d) The Company shall distribute Excess Contributions to
Highly Compensated Employees as provided in subsection (e) below to the extent necessary to satisfy one of the deferral percentage tests described below: 
 (i) The Average Deferral Percentage of Highly Compensated Employees who are Participants is not more than the product of 1.25 and the
Average Deferral Percentage of all Non-Highly Compensated Employees for the current Plan Year. 
 (ii) The Average Deferral
Percentage of Highly Compensated Employees who are Participants is not more than the lesser of (A) 200% of the Average Deferral Percentage of all Non-Highly Compensated Employees for the current Plan Year and (B) the Average Deferral
Percentage of all Non-Highly Compensated Employees for the current Plan Year, plus two percentage points. 
 In determining the Average
Deferral Percentages, the Deferral Percentages of all “Qualified Employees” shall be taken into account. For this purpose, a Qualified Employee is any Employee who is directly or indirectly eligible under the Plan to make Elective
Deferrals for all or a portion of a Plan Year and includes: 
 (A) an Employee who would be a Participant but for the failure
to make Elective Deferrals; 
 (B) an Employee whose eligibility to make Elective Deferrals has been suspended because of an
election not to participate or receipt of a distribution or a loan; and 
 (C) an Employee who is unable to make an Elective
Deferral because his Compensation is less than a stated dollar amount. In the case of a Qualified Employee who makes no Elective Deferrals, the Deferral Percentage that is to be included in determining the Average Deferral Percentage shall be zero.

  

 27 

 (e) Excess Contributions for the preceding Plan Year plus any income allocable to such
contributions shall be distributed no later than the last day of each Plan Year to the Highly Compensated Employees to whose accounts such Excess Contributions were allocated. Excess Contributions shall be treated as Annual Additions. The income
allocable to such contributions shall include the income accrued during the Plan Year for which the Excess Contributions were made and income for the period between the end of the Plan Year and the date of the distribution. Such income shall be
determined pursuant to procedures established by the Plan Administrator consistent with Code section 401(k)(8)(A) and Treasury regulation section 1.401(k)-1(f)(4). 
 (f) Distribution of Excess Contributions (plus any income or minus any loss allocable thereto) shall be made to Highly Compensated
Employees on the basis of the amount of the Excess Contributions by, or on behalf of, each Highly Compensated Employee. Excess Contributions shall be distributed from the Participant’s Deferral Account as follows: 
 (i) Calculate the dollar amount of Excess Contributions for each Highly Compensated Employee consistent with the provisions of Code
section 401(k)(8)(B). 
 (ii) Add the dollar amounts calculated in subsection (i) above to arrive at the total dollar
amount of the Excess Contributions for the Plan Year, and distribute such total amount in accordance with subsections (iii)-(v) below. 
 (iii) The Deferral Account of the Highly Compensated Employee with the highest dollar amount of Elective Deferrals for the Plan Year shall be reduced by the dollar amount required to cause such Highly Compensated
Employee’s Elective Deferrals for the Plan Year to equal the dollar amount of the Elective Deferrals of the Highly Compensated Employee with the next highest dollar amount of Elective Deferrals. Such reduction amount shall be distributed from
the Deferral Account of the Highly Compensated Employee. However, if a lesser reduction, when added to the total dollar amount already distributed pursuant to this subsection (iii) would equal the total Excess Contributions as determined
pursuant to subsection (ii) above, then the lesser reduction amount shall be distributed from such Highly Compensated Employee’s Deferral Account. 
 (iv) If the total amount distributed in subsection (iii) is less than the total Excess Contributions determined pursuant to
subsection (ii) above, then the reduction and distribution process in subsection (iii) above shall be repeated. 
  

 28 

 (v) No distributions of Excess Contributions (plus income) shall be made to any Highly
Compensated Employee as long as any other Highly Compensated Employee has a higher amount of Elective Deferrals. 
 Any reduction in the amount of Elective
Deferrals to be made on behalf of a Participant or any distribution of Excess Contributions under this subsection (e) will also be effective for purposes of determining the amount of Matching Contributions, if any, allocated to such Participant
under Section 5.3. 
 (g) The Deferral Percentage for any Participant who is a Highly Compensated Employee for the Plan
Year and who is eligible to have salary deferrals described in Code section 402(g)(3)(A) or qualified nonelective contributions described in Code section 401(m)(4)(C) allocated on his behalf under two or more plans or arrangements
described in Code section 401(k) that are maintained by the Company or any Affiliated Company shall be determined as if all such deferrals and contributions were made under a single arrangement. Notwithstanding the foregoing, certain plans
shall be treated as separate if mandatorily disaggregated under regulations under Code section 401(k). 
 (h) The Plan
Administrator may prescribe such rules as it deems necessary or appropriate regarding the maximum amount that a Participant may elect to defer and the timing of such an election. These rules may prescribe a maximum percentage of Compensation that
may be deferred, or may provide that the maximum percentage of Compensation that a Participant may defer will be a lower percentage of his Compensation above a certain dollar amount of Compensation than the maximum deferral percentage below that
dollar amount of Compensation. These rules shall apply to all individuals eligible to make the election described in Section 5.1, except to the extent that the Plan Administrator prescribes special or more stringent rules applicable only to
Highly Compensated Employees. 
 (i) The Plan Administrator may, in its discretion, estimate, as soon as is reasonably
possible prior to the close of the Plan Year, the extent (if any) to which deferral treatment under Code section 401(k) may not be available to any Participant (or class of Participants). If, pursuant to these estimates by the Plan
Administrator, a Participant (or a class of Participants) is not eligible for deferral treatment for any or all of the amounts deferred pursuant to the election set forth above in Section 5.1, then the Plan Administrator may authorize a
suspension of Elective Deferrals made pursuant to the provisions of Article V. This suspension shall be made pursuant to rules promulgated by the Plan Administrator. These rules may include 

  

 29 

 
provisions authorizing the suspension of Elective Deferrals above a specified dollar amount of Compensation, or any other means that the Plan Administrator
believes will help to ensure that deferral treatment will be available for all Participants. 
 (j) In the event that the Plan
Administrator determines that an amount to be deferred pursuant to the election provided in Section 5.1 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 XIII, the Plan Administrator may treat such amount in accordance with the
rules set forth above in Section 5.2(i). 
 5.3 Matching Contributions; Nondiscrimination Requirement and Distribution of Excess
Aggregate Contributions. 
 (a) Effective for Plan Years beginning on or after January 1, 1990, the Company may,
in its discretion, make a Matching Contribution in an amount equal to a percentage (determined each year in the Company’s discretion) for each $1 of a Participant’s Elective Deferrals up to a maximum of $5,000 of such Elective Deferrals,
subject to the limitations specified in Article XIII, except with respect to Participants who formerly participated in the NNS 401(k) Plan and whose accounts in that plan are transferred to the Plan pursuant to Section 5.6. With regard to
such Participants who formerly participated in the NNS 401(k) Plan, the Company, in its sole discretion, may make a Matching Contribution to those Participants alone and in an amount which is different than that available to other Participants,
subject to the limitations specified in Article XIII. 
 (b) The contribution described in Section 5.3(a) shall be
paid to the Trustee on the last day of the calendar quarter, or as soon as possible thereafter, but in any event no later than the date which is prescribed by law for filing the Company’s federal income tax return, including any extensions for
the taxable year with respect to which such contributions are made. A Matching Contribution shall be allocated as provided in Section 6.10(b) and made to each Participant, including former NNS employees, who is performing duties as a wage
earning Employee for the Company as of the last day of a calendar quarter and any Participant who dies, retires or becomes disabled during such quarter. Notwithstanding the above, for the period of January 1, 1995 through June 30, 1995,
Matching Contributions will be paid to the Trustee and allocated to each Participant’s account as of June 30, 1995 for those Participants who are employed on June 30, 1995. 
  

 30 

 (c) Excess Aggregate Contributions, plus any income or minus any loss allocable thereto
shall be forfeited, if forfeitable, or if not forfeitable, distributed to the Highly Compensated Employees to whose Accounts they were allocated, as set forth in subsections (d) and (e) below to the extent necessary to satisfy one of the
following contribution percentage tests: 
 (i) The Average Contribution Percentage of Highly Compensated Employees who are
Participants is not more than the product of 1.25 and the Average Contribution Percentage of all other Participants for the current Plan Year. 
 (ii) The Average Contribution Percentage of Highly Compensated Employees who are Participants is not more than the lesser of (A) 200 percent of the Average Contribution Percentage of all other Participants for
the current Plan Year and (B) the Average Contribution Percentage of all other Participants for the current Plan Year plus two points. 
 (d) In determining the Average Contribution Percentages, the Contribution Percentages of all “Qualified Employees” shall be taken into account. For this purpose, a Qualified Employee is any Employee who is
directly or indirectly eligible under the Plan to receive an allocation of Matching Contributions for all or a portion of a Plan Year and includes: 
 (i) an Employee who would be a Plan Participant but for the failure to make Elective Deferrals; 
 (ii) an Employee whose eligibility to make Elective Deferrals has been suspended because of an election not to participate or receipt of a hardship distribution; 
 In the case of a Qualified Employee who makes no Elective Deferrals, and thus receives no Matching Contributions, the Contribution
Percentage that is to be included in determining the Average Contribution Percentage shall be zero. 
 (e) Excess Aggregate
Contributions (plus any income or minus any loss allocable thereto) for a Plan Year, to the extent not vested pursuant to Article VII, shall be forfeited and to the extent vested, they shall be distributed no later than the last day of the next
succeeding Plan Year to those Highly Compensated Employees to whose accounts such Excess Aggregate Contributions were allocated. Excess Aggregate Contributions shall be treated as Annual Additions. 
  

 31 

 (f) Distribution of Excess Aggregate Contributions (plus any income or minus any loss
allocable thereto) shall be made to Highly Compensated Employees on the basis of the amount of the Matching Contributions on behalf of each Highly Compensated Employee. Excess Contributions shall be distributed from the Participant’s Matching
Contribution Account as follows: 
 (i) Calculate the dollar amount of Excess Aggregate Contributions for each Highly
Compensated Employee consistent with the provisions of Code section 401(m)(6)(D). 
 (ii) Add the dollar amounts
calculated in subsection (i) above to arrive at the total dollar amount of the Excess Aggregate Contributions for the Plan Year, and distribute such amount in accordance with subsections (iii)-(vi) below. 
 (iii) The Matching Contribution Account of the Highly Compensated Employee with the highest dollar amount of Matching Contributions for
the Plan Year shall be reduced by the dollar amount required to cause such Highly Compensated Employee’s Matching Contributions for the Plan Year to equal the dollar amount of the Matching Contributions of the Highly Compensated Employee with
the next highest dollar amount of Matching Contributions. Such reduction amount shall be distributed from the Matching Contribution Account of the Highly Compensated Employee. However, if a lesser reduction, when added to the total dollar amount
already distributed pursuant to this subsection (iii) would equal the total Excess Aggregate Contributions as determined pursuant to subsection (ii) above, then the lesser reduction amount shall be distributed from such Highly Compensated
Employee’s Matching Contribution Account. 
 (iv) If the total amount distributed in subsection (iii) is less than
the total Excess Aggregate Contributions determined pursuant to subsection (ii) above, then the reduction and distribution process in subsection (iii) above shall be repeated. 
 (v) Income or loss attributable to such Excess Aggregate Contributions shall be determined based on the income or loss in the Company
Contribution Account of each Highly Compensated Employee to whom such Excess Aggregate Contributions are distributed (or from whose accounts such Excess Aggregate Contributions are forfeited) for the Plan Year for which the Excess Aggregate
Contributions were made. Such income or loss shall be determined pursuant to procedures established by the Plan Administrator consistent with Code section 401(m)(6) and Treasury regulation section 1.401(m)-1(e)(3). 
  

 32 

 (vi) No distributions of Excess Aggregate Contributions (plus income) shall be made to
any Highly Compensated Employee as long as any other Highly Compensated Employee has a higher amount of Matching Contributions. 
 (g) The Contribution Percentage of a Highly Compensated Employee who is eligible to participate in two or more plans described in Code section 401(a) or arrangements described in Code section 401(k) maintained by the Company or an
Affiliated Company to which Matching Contributions or employee after-tax contributions are made shall be aggregated for purposes of determining such Employee’s Contribution Percentage. 
 (h) Any Excess Aggregate Contributions that are forfeited shall be added to Company Contributions and allocated as provided in
Section 6.12(a); provided, however, that forfeitures of Excess Aggregate Contributions shall not be allocated to the Account of any Highly Compensated Employee whose Matching Contributions Account is reduced pursuant to Subsection 5.3(f).

 (i) If one or more Highly Compensated Employees participates in a cash or deferred arrangement subject to the
nondiscrimination test in Code section 401(k) and a plan subject to the nondiscrimination test in Code section 401(m) that are maintained by the Company or an Affiliated Company, and the sum of the Average Deferral Percentage and Average
Contribution Percentage of the Highly Compensated Employees subject to either or both of those tests exceeds the aggregate limit defined below, the Matching Contribution Account of the Highly Compensated Employees who also participate in the cash or
deferred arrangement shall be reduced (beginning with the Highly Compensated Employee whose Matching Contributions for the Plan Year are the highest) to the extent necessary to come within the Applicable Limit. The amount by which each Highly
Compensated Employee’s Matching Contribution Account is reduced shall be treated as an Excess Aggregate Contribution. The Average Deferral Percentage and Average Contribution Percentage of the Highly Compensated Employees shall be determined
after any corrections required to meet the Average Deferral Percentage test and the Average Contribution Percentage test. Multiple use does not occur if either the Average Deferral Percentage or the Average Contribution Percentage of the Highly
Compensated Employee does not exceed 1.25 multiplied by the Average Deferral Percentage and Average Contribution Percentage of the Nonhighly Compensated Employees for the current Plan Year. Effective for Plan Years ending on or before
December 31, 2001, the provisions of Reg. Section 1.401(m)-2(b) shall apply for the purpose of applying the test for multiple use of the alternative limitation. 
  

 33 

 5.4 Termination of, Change in Rate of, or Resumption of Deferrals. 
 (a) A Participant may submit on form(s) prescribed by the Plan Administrator a request to the Plan Administrator that he wishes to
terminate, alter the rate of, or resume his Elective Deferrals made pursuant to this Article V. Such changes may be made once each month. 
 (b) This request for termination, alteration, or resumption shall be effective as soon as practicable, subject to Section 5.2(i), and shall be effective on the later of the date specified in the notice of the
change and the date which is fifteen days after the notice is received by the Plan Administrator. 
 5.5 Rollover Contributions From
Other Plans. An Eligible Employee, regardless of whether he has satisfied the participation requirements of Section 3.1, may contribute to the Trust Fund a Rollover Contribution pursuant to procedures approved by the Plan Administrator.
The Plan Administrator shall develop such procedures and may require such information from an Employee desiring to make such a contribution as it deems necessary or desirable to determine that the proposed contribution will meet the requirements of
a Rollover Contribution. Upon approval by the Plan Administrator, the amount contributed 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 6.11, but shall not share in allocations of any Profit Sharing Contributions. Upon termination of employment, the total amount of the Voluntary Account shall be distributed as soon as practicable
following termination of employment or, if the Employee so elects, treated as part of the Employee’s “Distributable Benefit” under Section 8.5 and distributed in accordance with Sections 8.1 through 8.7, as applicable.

 Upon such contribution by an Employee who is otherwise eligible to participate in the Plan, but who has not yet completed the
participation requirements of Section 3.1, his Rollover Account shall represent his sole interest in the Plan until he becomes a Participant. 
 5.6 Plan-to-Plan Transfers. In its sole discretion, the Plan Administrator may authorize (subject to procedures established by the Plan Administrator) the Trustee to accept a transfer, from a plan qualified under Code
section 401(a), of a Participant’s account(s) balance under such transferee plan but 

  

 34 

 
only to the extent such account(s) balances are in cash and satisfy each of the following requirements: 
 (a) If it is made to this Plan from a plan which contained Protected Benefits, such Protected Benefits shall continue to be maintained
with respect to the amounts transferred whether in the Participant’s NNS Transfer Accounts or in the Participant’s other Accounts, depending upon the character of the contribution under the transferee plan. 
 (b) To the extent required by Code section 411(d)(6), and pursuant to procedures established by the Company, an amount transferred to the
Participant’s Accounts, including a Participant’s NNS Transfer Accounts, if any, pursuant to this Section 5.6 shall retain the Protected Benefits that were applicable to such Account balance prior to the transfer to the Plan.
Notwithstanding the foregoing, the Company reserves the right to eliminate all or any of such Protected Benefits if and to the extent permitted by Code section 411(d)(6) and any regulations or guidance promulgated thereunder. 
 5.7 Voluntary Contributions. No Voluntary Contributions are permitted subsequent to December 31, 1986. Voluntary Contributions made
prior to such date shall be maintained in a Voluntary Account as set forth herein. 
  

 35

 6.10 Allocation of Company Contributions. 
 (a) All Company Contributions on account of Elective Deferrals shall be allocated to Participants’ Deferral Accounts as soon as practicable following their contribution to the Trust, but in no event later than
ninety (90) days after such amounts were deferred. 
 (b) All Company Contributions which constitute Matching
Contributions shall be allocated to Participants’ Company Contribution Accounts within ninety (90) days following their contribution to the Trust. An allocation shall be made on behalf of a Participant who is otherwise eligible to receive
a Matching Contribution only if such Participant is a wage-earning Employee of the Company on the last day of the calendar quarter, or if such Participant dies, retires or becomes disabled during such quarter. 
 (c) Any Company Contributions which constitute Profit Sharing Contributions shall be allocated to the Company Contribution Account of each
Participant who is performing duties as a wage-earning Employee of the Company on the last day of the Plan Year. An allocation also shall be made for any Participant who dies, retires or becomes disabled during the Plan Year. The Profit Sharing
Contribution shall be allocated to each Participant eligible to receive a share of such contribution (except for those Participants who formerly participated in the NNS 401(k) Plan) in the proportion that the Compensation paid to each such
Participant during the Plan Year bears to the Compensation paid to all such Participants. With respect to Participants who formerly participated in the NNS 401(k) Plan and whose accounts in that plan were transferred to the Plan pursuant to
Section 5.6, any Profit Sharing Contribution shall be allocated among each such Participant who is otherwise eligible to receive a share of such contribution in the proportion that the Compensation paid to each such Participants during the Plan
Years bears to the Compensation paid to all such Participants who formerly participated in the NNS 401(k) Plan. 
 (d) Any
Company Contributions for a Plan Year which constitute Additional Company Contributions shall be held on an unallocated basis until allocated to Participants’ Deferral Accounts as provided under this Plan. Prior to allocation, these
contributions shall not be adjusted for any income, gain or loss thereon, which shall be allocated separately pursuant to Section 6.13. 
  

 37 

 (e) Company Contributions in the form of Additional Company Contributions shall be
allocated to Participants’ Deferral Accounts so as to allow the Plan to satisfy the nondiscrimination test set forth in Code section 401(k)(3)(A)(ii) and Section 5.2(d) of the Plan as applied to Elective Deferrals and the
nondiscrimination test set forth in Code section 401(m)(2) and Section 5.3 of the Plan as applied to Matching Contributions. Subject to the limitations of Article XIII of this Plan and to the requirements of Code sections
401(k)(3)(A)(ii) and 401(m)(2), effective January 1, 1992, Additional Company Contributions shall be allocated as an equal dollar amount to Deferral Accounts of all Eligible Employees who are Nonhighly Compensated Employees who are taken into
account in the nondiscrimination tests set forth in Sections 5.2 and 5.3 of the Plan. 
 (f) Company Contributions
made pursuant to Section 6.13 shall not be allocated to Accounts of Participants, but (together with any gains or income thereon) shall be applied to defray Plan expenses. 
 (g) In no event shall amounts be allocated which would cause the limitation on Annual Additions set forth in Article XIII to be
exceeded. 
 (h) Company Contributions in the form of Company Stock shall be allocated to the Accounts of the Participants
based on the fair market dollar value of such contributed Company Stock as determined under the provisions of Section 6.11(b)(ii), unless a different valuation method shall be required under the applicable Treasury regulations. 
 6.11 Valuation of Accounts. 
 (a) As of each Valuation Date and within sixty (60) days after the removal or resignation of the Trustee, and at such other times as determined by the Plan Administrator, the Trustee shall value the assets of the
Trust on the basis of fair market values. 
  

 38 

 (b) As soon as is reasonably possible after receipt of these valuations from the Trustee,
the Plan Administrator 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 6.11 shall be applied and implemented in accordance with the following rules: 
 (i)
If separate subaccounts have been established for separate investment alternatives, each subaccount shall be valued separately and the total value of a Participant’s Account(s) shall equal the total value of his interest in each of the
respective subaccounts in which his Account(s) have been invested. 
 (ii) Company Stock allocated and credited to an Account
or subaccount, or to a separate fund within the Trust Fund in which Participants’ Accounts or subaccounts are invested as provided in Section 4.6, as well as Company Stock held on an unallocated basis in the Trust Fund, shall be valued as
of the applicable Valuation Date, according to the following rules: 
 (A) Company Stock acquired by the Trust Fund with cash
shall initially be valued at the purchase price paid for such stock. On any subsequent Valuation Date, such Company Stock, as well as all other Company Stock held in, or contributed to, the Trust Fund, shall be valued in accordance with
Section 6.11(b)(ii)(B) or 6.11(b)(ii)(C) below, as applicable. 
 (B) If any Company Stock does not consist of
securities listed on a national securities exchange, or traded on a regular basis, as determined by the Company, in the over-the-counter market, the fair market value of such stock shall be determined using the formula price for such stock, as
described in the August 24, 1987 Prospectus for Science Applications International Corporation (or the most recent prospectus that supersedes that prospectus), on the applicable Valuation Date. The Plan Administrator may at any time, and from
time to time, change the method of determining the fair market value of Company Stock, provided that the replacement method is consistent with applicable provisions of ERISA and the Code. A Participant, Beneficiary or Alternate Payee shall have no
right to have a particular valuation method applied (or continue to be applied) to his Account(s). 
 (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 trading day immediately preceding the day 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 

  

 39 

 
automatic quotation system of a securities association registered under the federal securities laws for the trading day immediately preceding the applicable
Valuation Date. 
 (iii) The fair market value of any guaranteed interest contract, trust or fund holding such a contract, or
similar program entered into between an insurance company and the Plan shall be determined based on the principal amount of such contract or program, plus the amount of the guaranteed interest or other increase in value which is paid or credited to
the Plan pursuant to such contract or program. The provisions of this subparagraph (iii) shall apply to any investment alternative established under Section 4.6 which is invested in such a contract or program. 
 (iv) To the extent that a Participant’s Account is invested in a regulated investment company offered as an investment alternative
under the Trust, the value of that portion of the Account shall be valued, pursuant to rules prescribed by the Plan Administrator, based on the unit or share value of the regulated investment company on the applicable Valuation Date. 
 (c) The Company, the Plan Administrator 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. 
 (d) Allocation of Company Stock Received Pursuant to Stock Dividends, Splits, Recapitalizations, Etc. Any Company 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 Stock Rights, Warrants or Options. 
 (i) In the event any rights, warrants or options are issued on Company Stock held in the Trust Fund, the Trustee shall exercise them for
the acquisition of additional Company Stock as directed by the Plan Administrator and to the extent that cash is then available in the Trust Fund. 
 (ii) Any Company Stock acquired in this fashion shall be treated as Company Stock purchased by the Trustee for the net price paid and shall be allocated in the same manner as the funds used to purchase the Company
Stock were or would be 

  

 40 

 
allocated under the provisions of this Plan, pursuant to directions of the Plan Administrator. 
 (iii) Any rights, warrants, or options on Company Stock which cannot be exercised for lack of cash may, as directed by the Plan
Administrator, be sold by the Trustee and the proceeds allocated in accordance with the source of the Company Stock with respect to which the rights, warrants or options were issued. 
 (f) 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 4.6, 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 Participants’ Account or subaccount. 
 (ii) All cash dividends paid to the Trustee with respect
to unallocated Company Stock shall be allocated as provided in Section 6.13. 
 (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 4.6, as prescribed by the Plan Administrator. 
 6.12 Allocation of Forfeitures. The treatment of all amounts that are forfeited by reason of the termination of the employment of a
Participant shall be governed by the following rules, effective January 1, 1992: 
 (a) Forfeitures shall be used to
offset the Company’s obligation to make Company Contributions and shall be allocated to the Matching Contribution Accounts of those Participants who are entitled to receive an allocation of Matching Contributions for the Plan Year in the manner
prescribed in Section 6.10(b). 
 (b) No forfeitures shall be allocated to any Voluntary Account, Rollover Account,
Deferral Account or Alternate Payee Account. 
  

 41 

 (c) The forfeitures to be allocated shall be the amount of forfeitures occurring since
the next preceding allocation under this Section 6.12 and prior to the date prescribed by the Plan Administrator as the cutoff date for such allocation, which shall be a date falling between the Anniversary Date and the actual date in which the
allocations are made. Such date may be changed from time to time by the Plan Administrator. 
 (d) Pending allocation,
forfeitures shall be accounted for in the same manner as unallocated Company Contributions and shall not be adjusted for income, gain or loss on such forfeitures. Such income, gain or loss shall be considered and accounted for in the same fashion as
income, gain or loss on unallocated Company Contributions. 
 (e) For periods prior to January 1, 1991, forfeitures
occurring during a Plan Year were allocated in the same manner as Profit Sharing Contributions. 
 6.13 Allocation of Income or Loss on
Unallocated Company Contributions; Company Contributions to Defray Plan Expenses. At the time Company Profit Sharing Contributions are allocated to Company Contribution Accounts, the income, gain or loss on unallocated Company Contributions
(determined as of the end of the Plan Year preceding the actual allocation date), 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 Contributions for such Plan Year, pro rata, according to each such Participant’s entitlement to such
allocation. The Company may, in its discretion, make a Plan contribution at any time for the purpose of defraying Plan expenses. Such contribution shall be used to defray Plan expenses and shall not be allocated to Accounts of Participants.

 6.14 Accounting Procedures. The Plan Administrator shall establish accounting procedures for the purpose of making the
allocations, valuations and adjustments to Accounts provided for in this Article VI, as well as the implementation of investment direction by Participants pursuant to Section 4.6 and transfers between or distributions from subaccounts
established pursuant to Section 4.6(b). From time to time the Plan Administrator 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 VI. 
  

 42 

 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 Plan Administrator 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). 
 6.15 Suspended Participants. The Accounts of each Suspended Participant shall
be held intact and shall be valued on each Valuation Date as provided in Section 6.11, but shall not receive any allocation of Company Contributions; provided, however, that if the Participant completes, during the Plan Year in which he becomes
a Suspended Participant, 1,000 or more Hours of Service during such Plan Year, his Company Contribution Account shall participate in the allocation of Profit Sharing Contributions for such Plan Year, if he otherwise would have been eligible for such
an allocation. 
 6.16 Qualified Military Service. Effective December 12, 1994, notwithstanding any provision of this Plan
to the contrary, Company Contributions, benefits and service credit with respect to qualified military service will be provided in accordance with Section 414(u) of the Code. 
 6.17 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 14.2, such interest shall be separated into one or more separate Accounts and accounted for under rules prescribed by the Plan Administrator, pending
distribution to the Alternate Payee. 
  

 43 

 ARTICLE VII 
 VESTING IN ACCOUNTS 
 7.1 No Vested Rights Except as Herein Specified. No Participant,
Beneficiary or Alternate Payee shall have any vested right or interest to, or any right of payment of, any assets of the Trust Fund, except as provided in this Plan. Neither the making of any allocations nor the crediting of any amounts to the
Account of a Participant, Beneficiary or Alternate Payee shall vest in any Participant, Beneficiary or Alternate Payee any right, title, or interest in or to any assets of the Trust Fund. 
 7.2 Participant’s Vested Interest—General Rule. Subject to the provisions of Section 7.3 and 7.6, the Vested Interest of
each Participant or Suspended Participant in his Company Contribution Account shall be determined by multiplying the balance in each such account as of the applicable date by the Vested Percentage determined in accordance with the rules of
Section 7.3 and the following schedule: 
  

				
	 Years of Service
	  	Vested
Percentage	 
	 Less than three years
	  	0	 
	 Three years but less than five years
	  	50	%
	 Five years or more
	  	100	%

 7.3 Vested Percentage—Special Rules. The determination of a Participant’s
or Suspended Participant’s Vested Percentage in his Company Contribution Account shall be subject to the following special rules: 
 (a) During an Employee’s period of employment with the Company or an Affiliated Company (including periods while on an approved leave of absence or a Maternity or Paternity absence), in the event of his death,
Disability, attainment of Normal Retirement Age, or a judicial declaration of his mental incompetence, the Employee’s Vested Percentage shall become one hundred percent (100%), regardless of his number of Years of Service. 
 (b) For Plan Years beginning on and after January 1, 1992, the following rules shall apply: 
 (i) If a Participant terminates employment with the Company before becoming fully vested in his Accounts, and does not elect to receive a
distribution, the nonvested portion of his Accounts shall be forfeited at the time the Participant incurs five consecutive Breaks in Service. If the Participant resumes employment with the Company prior to incurring five 

  

 44 

 
consecutive Breaks in Service, his Vested Percentage shall be determined as if he had not terminated employment. 
 (ii) If a Participant terminates employment with the Company before becoming fully vested in his Company Contribution Account, and
voluntarily elects to receive a distribution at termination, the nonvested portion of such Participant’s Company Contribution Account shall be forfeited at the time the Participant incurs a Break in Service. 
 (iii) If the nonvested portion of a Participant’s Company Contribution Account is forfeited as described in clause (ii), and the
Participant returns to employment prior to incurring five consecutive Breaks in Service, the amount forfeited shall be restored to his Company Contribution Account if the Participant repays to the Plan the full amount of the distribution
attributable to contributions made by the Company before the earlier of (A) five years after the first date on which the Participant is subsequently reemployed by the Company, or (B) the date on which the Participant incurs five
consecutive Breaks in Service. Reinstatement shall be made on the last day of the Plan Year coinciding with or following the Employee’s Reemployment Commencement Date. Restoration shall be made from available funds in the following order: first
from forfeitures occurring on the last day of the Plan Year coinciding with or following the Employee’s Reemployment Commencement Date, and second, from extraordinary contributions made by the Company. 
 (iv) If a Participant terminates employment with the Company when the value of the Participant’s Distributable Benefit is $5,000 or
less, the Participant shall receive such Distributable Benefit as soon as practicable following termination of employment. The nonvested portion of such Participant’s Accounts shall be forfeited at the date the Participant receives distribution
of his Distributable Benefit. If the Participant resumes employment with the Company prior to incurring five consecutive Breaks in Services, and repays the amount distributed, as described in clause (iii), the nonvested portion shall be restored as
provided in clause (iii). If a Participant has no vested interest in his Accounts, the Participant shall be deemed to have received a distribution of his Distributable Benefit. 
 (v) An Employee’s aggregate Years of Service shall not include any Years of Service not required to be taken into account under this
Section 7.3(b) by reason of any prior Break in Service. 
 (c) An Employee’s Vested Percentage as of January 1,
1992 shall be equal to his Vested Percentage determined as of 

  

 45 

 
December 31, 1991, under the terms of the Amended and Restated Plan as in effect on September 30, 1989. 
 (d) In the event of a divestiture of an operating group or division, the Plan Administrator or the Plan Administrator’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 Percentage specified in this Article
VII, (1) treat the Eligible Employees’ Vested Percentage 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 Percentage. Any such determination for a particular group or division shall not bind the Company in any way with respect to any subsequent
determination relating to a different group or division. In the event of a subsequent divestiture from the new employer, the Plan Administrator or the Plan Administrator’s designee may make a similar determination regarding vesting
acceleration. 
 7.4 Nonforfeitable Accounts. The Vested Interest of each Participant in his Deferral Account, Voluntary
Account and Rollover Contributions Account shall at all times be 100 percent. 
 7.5 Alternate Payee Accounts. In the
event that an Alternate Payee is awarded an interest in the Accounts of a Participant whose Vested Percentage in any such Account is less than 100%, the Vested Percentage at any time of the Alternate Payee in that portion of the Alternate Payee
Account attributable to such awarded interest shall be the same percentage as the Participant’s Vested Percentage in his Account at that time, determined in accordance with Sections 7.1 through 7.3. 
 7.6 Participants Vested Interest. 
 (a) Notwithstanding the above, effective January 1, 1997, the Vested Interest in the Company Contribution of each Participant actively employed on January 1, 1997 shall be at all times 100%.

 (a) A Participant who attains Normal Retirement Age shall be fully vested in his Accounts and shall be entitled to receive a distribution
of his Distributable Benefit as of his Normal Retirement Date. The value of his Distributable Benefit shall be based on the value of his Account as of the Applicable Valuation Date. 
 (b) If the Participant continues in the service of the Company beyond his Normal Retirement Date with the consent of the Company
consistent with applicable legal requirements, he shall continue to participate in the Plan in the same manner as Participants who have not reached their Normal Retirement Dates. At the subsequent termination of the Participant’s employment
with the Company, his Distributable Benefit shall be based upon the value of his Accounts as of the Applicable Valuation Date determined with reference to his date of termination of employment as though that were his Normal Retirement Date.

 8.2 Other Termination of Employment. A Participant who terminates employment with the Company for any other reason other
than retirement on or after Normal Retirement Age, shall be entitled to receive a distribution of his Distributable Benefit as soon as reasonably practicable but in no event later than 120 days following the end of the Plan Year in which the
Participant terminates his employment. A Participant shall be deemed to have terminated employment on the date the Plan Administrator determines the Participant has incurred a Disability. The value of his Distributable Benefit shall be based on the
value of his Account as of the Applicable Valuation Date. 
 8.3 Withdrawals of Voluntary Contributions and from NNS Transfer Accounts;
Hardship Withdrawals. 
 (a) A Participant (except a Participant who formerly participated in the NNS 401(k) Plan)
shall be entitled to make a withdrawal from his Voluntary Account at any time, subject to procedures established by the Plan Administrator. A Participant who formerly participated in the NNS 401(k) Plan and had accounts in that plan transferred to
the Plan, shall be entitled to make a withdrawal from his NNS Transfer After-Tax Account, NNS Transfer Employer Account, or NNS Transfer Rollover Account at any time, subject to procedures established by the Plan Administrator. 
  

 47 

 (b) Further, a Participant (except a Participant who formerly participated in the NNS
401(k) Plan), may withdraw amounts from his Deferral Account that are attributable to Elective Deferrals, excluding all earnings attributable thereto, upon incurring a financial hardship as determined by the Plan Administrator. A Participant who
formerly participated in the NNS 401(k) Plan shall be entitled to make withdrawals from his Deferral Account and his NNS Transfer Deferral Account that are attributable to Elective Deferrals, excluding all earnings attributable thereto, upon
incurring a financial hardship as determined by the Plan Administrator. A withdrawal will be deemed made on account of financial 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 paragraph shall be made in accordance with rules prescribed by the Plan Administrator 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 Plan
Administrator 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: 
 (A) Medical expenses of the Employee or his dependent(s) not covered by insurance; 
 (B) Purchase of the principal residence for the Employee; 
 (C) Payment of tuition for the next twelve months of post-secondary education for the Employee or his dependent(s); 
 (D) The need to prevent the eviction from the Employee’s principal residence or foreclosure on the mortgage of the Employee’s
principal residence; or 
 (E) Other financial circumstances as the Plan Administrator may determine, consistent with
applicable regulations and rulings of the Treasury Department and the Internal Revenue Service.

the applicant: 
 (A) The applicant must sign the forms provided by the Plan Administrator and certify all information

applicant must have applied for all eligible loans from this Plan or from any other Company retirement plans which permit Participant loans; 
 (D) The hardship withdrawal normally cannot be less than $500.00; 
 (E) The applicant must
suspend all Elective Deferrals for twelve (12) months after receiving the hardship withdrawal pursuant to rules prescribed by the Plan Administrator; and 
 (F) The maximum amount of Elective Deferrals for the calendar year following the year of the hardship withdrawal will be the maximum
amount permitted by Code section 402(g) for such calendar year less the amount of any Elective Deferrals made by the Participant during the calendar year in which such Hardship withdrawal is made. 
 (iii) In the event that a Participant has elected to have his Deferral Account invested in more than one investment alternative, then the
withdrawal shall be made pro rata from the subaccounts in which his Accounts are 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 Plan Administrator. 
 (c) Upon fifteen (15) days’ written notice to the Plan Administrator, and not more than once each Plan Year, a Participant may withdraw up to one hundred percent (100%) of the balance in his Voluntary Account as
soon as administratively feasible following submission of the withdrawal request. 
 (d) Any withdrawal made under this
Section 8.3 shall be subject to the restrictions on distributions set forth in Sections 8.6 through 8.8. 
 8.4 Withdrawals After
Age 59 1/2. On or after a Participant reaches the age of 59 1/2, he may make
unlimited withdrawals of any amount from any or all of his Accounts as set forth in Section 2.1. 
  

 49 

 8.5 Distributable Benefit. 
 (a) A Participant’s “Distributable Benefit” shall be his entire nonforfeitable interest in his Accounts. This amount shall
be distributable in the forms described in Section 8.6, subject to the restrictions on distributions set forth in Sections 8.7 and 8.8. 
 (b) 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 VIII, the value of the Participant’s Accounts
shall be determined in accordance with rules prescribed by the Plan Administrator. However, the value of the Participant’s Accounts shall be increased or decreased (as appropriate) by any contributions or distributions properly allocable under
the terms of this Plan to his Accounts 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) Neither the Plan Administrator, 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 Distributable Benefit to him or his Beneficiary. Also,
neither the Plan Administrator, the Company, nor the Trustee shall have any responsibility for failing to make any interim valuation of a Participant’s Accounts between the date of distribution to the Participant of his Distributable Benefit
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. 
 8.6 Optional Forms of Payment. 
 (a) Each Participant may elect, with his spouse’s consent if required and subject to (b) below, to receive his Distributable Benefit in one of the following forms, or a combination of such forms, subject to
the provisions of Sections 8.7 and 8.8:

beyond the life expectancy of the Participant. 
 (ii) A period certain not extending beyond the joint life and last survivor
expectancy of the Participant and a designated Beneficiary. 
 (iii) The Participant’s life. 
 (iv) The lives of the Participant and the Participant’s designated Beneficiary. 
 (c) With respect to any Participant whose Plan Accounts contain no allocations made prior to January 1, 1992, the only available
benefit option is a single sum distribution. 
 8.7 Direct Rollover. 
 (a) This Section 8.7 applies to distributions made on or after January 1, 1993. Notwithstanding any provision of the Plan to the
contrary that would otherwise limit a “distributee’s” election under this Section 8.7, a distributee may elect, at the time and in the manner prescribed by the Plan Administrator, to have any portion of an “eligible rollover
distribution” paid directly to a “eligible retirement plan” specified by the distributee in a direct rollover. 
 (b) “Eligible rollover distribution” means any distribution of all or any portion of the balance of the credit of the distributee, except that an eligible rollover distribution does not include: any distribution that is one of a
series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the distributee or the joint lives (or joint life expectancies) of the distributee and the distributee’s designated
beneficiary, or for a specified period of ten years or more; any distribution to the extent such distribution is required under section 401(a)(9) of the Code; any hardship distribution made under Code section 401(k)(2)(B)(i)(IV) for distributions
after December 31, 1998; 

  

 51 

 
and the portion of any distribution that is not includable in gross income (determined without regard to the exclusion for net unrealized appreciation with
respect to employer securities). 
 (c) “Eligible retirement plan” means an individual retirement account described
in section 408(a) of the Code, an individual retirement annuity described in section 408(b) of the Code, an annuity plan described in section 403(a) of the Code, or a qualified trust described in section 401(a) of the Code, that accepts the
distributee’s eligible rollover distribution. However, in the case of an eligible rollover distribution to the surviving spouse, an eligible retirement plan is an individual retirement account or individual retirement annuity. 
 (d) 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 an Alternate Payee are distributees with regard to the interest of the spouse or former spouse. 
 (e) A “direct rollover” is a payment by the Plan to the eligible retirement plan specified by the distributee. 
 8.8 Distribution Restrictions on Plan Account and Matching Account Notwithstanding the prior provisions of this Article VIII to the
contrary, a Participant’s Plan Account and Matching Account Balances shall not be distributable earlier than: 
 (a) Upon
termination of the Participant’s employment with the Company on or after the date he or she attains Normal Retirement Date or by reason of death; 
 (b) Upon a determination by the Committee that the Participant has become Disabled; 
 (c)

application for a hardship or in-service withdrawal, but only to the extent provided in Section 8.7;

Company’s disposition of corporate assets or a subsidiary; and

Payee’s right to all or a portion of a Participant’s Plan and Matching Contribution Accounts under a domestic relations order which the Committee determines is a qualified domestic relations order as provided in Section 14.2, but only
as to the portion which is payable to the Alternate Payee. 
 8.9 Distribution Rules. The provisions of Section 8.8(a)
shall apply to the Distributable Benefit of a Participant who does not elect, and has not previously elected, a life annuity under the Plan. The provisions of Section 8.8(b) shall apply to the Distributable Benefit of a Participant who elects,
or has previously elected, a life annuity under the Plan. 
 (a)(i) Upon termination of employment with the Company for any
reason other than death, a Participant who does not elect to receive a life annuity under the Plan shall be entitled to a single sum payment of his entire Distributable Benefit. Payment shall be made in the form and at the time determined under
Sections 8.6 and 8.7. 
 (ii) If the Participant has a Distributable Benefit remaining at his death, and has not elected a
life annuity under the Plan, the Participant’s benefit shall be paid to the Participant’s surviving spouse. If there is no surviving spouse, or if the surviving spouse has consented in a manner conforming to the requirements of a Qualified
Election as described below to a different Beneficiary designation, the Participant’s Distributable Benefit shall be paid to the Participant’s designated Beneficiary. The Participant’s spouse may waive the spousal death benefit
described above at any time, but the waiver shall not be effective unless it satisfies the requirements for a Qualified Election with respect to a Qualified Preretirement Survivor Annuity. The Plan Administrator shall direct the Trustee to pay out
the Participant’s benefits in the form elected by the Beneficiary subject to the provisions of Sections 8.6 and 8.7. 
 (b)(i) If a married Participant who has elected to receive a life annuity under the Plan dies prior to his Annuity Starting Date, is survived by a spouse and has not made a Qualified Election within the Election Period, the
Participant’s Distributable Benefit shall be used to provide a Qualified Preretirement Survivor Annuity providing for payments over the 

  

 53 

 
life of the Participant’s surviving spouse. The surviving spouse may elect to have distributions commence within a reasonable period after the
Participant’s death or to defer distribution as provided in Section 8.6. 
 (ii) If a married Participant is alive
on his Annuity Starting Date and does not make a Qualified Election within the Election Period, the Participant’s Distributable Benefit shall be used to provide a Qualified Joint and Survivor Annuity providing payments over the joint life of
the Participant and the Participant’s spouse and the life of the survivor. The Participant shall designate on the form provided by the Plan Administrator the amount of the survivor annuity expressed as a percentage of the amount payable during
the joint life of the Participant and his spouse. The Participant may elect to have such annuity distributed upon attainment of the earliest date on which the Participant may elect to receive retirement benefits. 
 (iii) If the Participant is unmarried on his Annuity Starting Date, or has certified that his spouse cannot be located, and does not make
a Qualified Election within the Election Period, the Participant’s Distributable Benefit shall be used to provide a single life annuity providing payments over the life of the Participant. 
 (iv) Within the Applicable Notice Period, the Plan Administrator shall provide each Participant with a written explanation of the terms
and conditions of the Qualified Preretirement Survivor Annuity and the Qualified Joint and Survivor Annuity; the Participant’s right to make, and the effect of, an election to waive such annuities; the requirement for spousal consent to the
election to waive such annuities; the material features and optional forms of benefit; and the right to make, and the effect of, a revocation of an election to waive such annuities. 
 (v) If the Participant makes a Qualified Election within the Election Period, the Participant, or the Participant’s designated
Beneficiary in the event of the Participant’s death, may elect to receive benefits in one of the forms described in Section 8.6. 
 (c) The following definitions shall apply with respect to this Section 8.9 in addition to the definitions in Article II of the Plan:

form. 
  

 54

ending after the individual becomes a Participant. 
 (3) Notwithstanding clause (i), a reasonable period ending
after the date the Participant terminates employment with the Company, if the Participant terminates employment before attaining age thirty-five (35). 
 (B) For a Qualified Joint and Survivor Annuity, a reasonable period which shall not be less than thirty (30) days nor more than ninety (90) days before the Participant’s Annuity Starting Date.

 (C) For purposes of clause (ii), a ”reasonable period” shall be the end of the two-year period
beginning one year before the described event occurs and ending one year after that date. For purposes of clause (iii), a ”reasonable period” shall include the two-year period beginning one year before the Participant terminates
employment with the Participating Employer and ending one year after such termination. If the Participant returns to employment with the Participating Employer, the Applicable Notice Period shall be redetermined. 
 (iii) “Election Period” means: 
 (A) For a Qualified Preretirement Survivor Annuity, the period which begins on the first day of the Plan Year in which the Participant attains age thirty-five (35) and ends on the date of the Participant’s
death. If a Participant terminates employment with the Company before the first day of such period, the Election Period shall begin on the date on which the Participant terminates employment with the Company with respect to benefits previously
accrued. A Participant who will not yet attain age thirty-five (35) as of the end the current Plan Year may make a special Qualified Election to waive the Qualified Preretirement Survivor Annuity for the period beginning on the date of such
election and ending on the first day of the Plan Year in which the Participant will 

  

 55 

 
attain age thirty-five (35). Such election shall not be valid unless the Participant receives a written explanation of the Qualified Preretirement Survivor
Annuity in terms similar to those described in subsection (c) above. Qualified Preretirement Survivor Annuity coverage shall be reinstated as of the first day of the Plan Year in which the Participant attains age thirty-five (35). Any waiver
after such date must meet the requirements of a Qualified Election in order to be valid. 
 (B) For a Qualified Joint and
Survivor Annuity, the ninety-day period ending on the Participant’s Annuity Starting Date. 
 (iv) “Qualified
Election” means an election by a Participant to waive a Qualified Joint and Survivor Annuity or Qualified Preretirement Survivor Annuity which meets the following requirements: 
 (A) The Participant’s spouse consents in writing to the election. 
 (B) The election designates a specific Beneficiary, including any class of Beneficiaries or contingent Beneficiaries, which may not be
changed without spousal consent, or the spouse expressly permits designations by the Participant without further spousal consent. 
 (C) The election designates a form of benefit payment that may not be changed without spousal consent (or the spouse expressly permits designation by the Participant without any further spousal consent). If it is established to the
satisfaction of a Plan representative that there is no spouse, or that the spouse cannot be located, a waiver shall be deemed a Qualified Election. 
 (D) The spouse’s consent acknowledges the effect of the election. 
 (E) The
spouse’s consent is witnessed by a Plan representative or a notary public. 
 (F) The Participant has received notice as
described in clause (iv) within the Applicable Notice Period. Any consent made by a spouse to a Participant’s election to waive an annuity shall be effective only with respect to such spouse. A consent which permits designation by the
Participant without any requirement of further consent by such spouse shall acknowledge that the spouse has the right to limit consent to a specific Beneficiary, and a specific form of benefit where applicable, and that the spouse voluntarily elects
to relinquish 

  

 56 

 
either or both such rights. A revocation of a prior waiver may be made by a Participant without the consent of the spouse at any time before the commencement
of benefits. The number of revocations shall not be limited. 
 (v) “Qualified Joint and Survivor Annuity” means an
immediate annuity for the life of the Participant with a survivor annuity for the life of the spouse which is not less than 50 percent and not more than 100 percent of the amount of the annuity that is payable during the joint life of the
Participant and the spouse. The percentage of the survivor annuity shall be 50 percent unless the Participant designates a different percentage. 
 (vi) “Qualified Preretirement Survivor Annuity” means an immediate annuity for the life of the surviving spouse of the Participant. 
 8.10 Designation of Beneficiary. 
 (a) Subject to the provisions of Section 8.10(e), each Participant shall have the right to designate a Beneficiary or Beneficiaries to receive his Distributable Benefit. This designation is to be made on the form
prescribed by and delivered to the Plan Administrator or its delegate. 
 (b) Subject to the provisions of
Section 8.10(e), a Participant shall have the right to change or revoke any such designation by filing a new designation or notice of revocation with the Plan Administrator. Subject to the provisions of Section 8.10(e), no notice to any
Beneficiary nor consent by any Beneficiary shall be required to effect any such change or revocation. 
 (c) If a deceased
Participant shall have failed to designate a Beneficiary, if the Plan Administrator 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 estate
(except as provided in Section 8.10(e)), and the estate shall be considered the Beneficiary under this Plan. 
 (d) In
the event that the deceased Participant was not a resident of Virginia at the date of his death, the Plan Administrator, in its discretion, may require the establishment of ancillary administration in Virginia. In the event that a Participant shall
predecease his Beneficiary and on the 

  

 57 

 
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) If a Participant shall be married at the time of his death, the designation by the
Participant under Section 8.10 of a person other than the current spouse as his Beneficiary shall not take effect (and the entire Distributable Benefit shall be paid to such spouse) (i) unless the spouse of the Participant consents in
writing to such designation, and the spouse’s consent acknowledges the effect of such designation and is witnessed by the Plan Administrator (or its delegate), a notary, or (ii) unless it is established to the satisfaction of the Plan
Administrator that such consent is not required because there is no spouse, because the spouse cannot be located, or because of such other circumstances as the Secretary of the Treasury may by regulations prescribe. 
 (f) The Company, the Plan Administrator and the Trustee shall have no duty to determine whether a Beneficiary designation or spousal
consent made pursuant to this Section 8.10 was an informed designation or consent or was freely given, and shall be entitled to rely upon the Beneficiary form filed with the Plan Administrator, as well as such other documents as may be required
pursuant to Section 8.13, and shall be under no duty or obligation to protect the rights of a spouse or former spouse of a Participant, except as may be required by law. 
 8.11 Facility of Payment. If any payee under the Plan is a minor or if the Plan Administrator reasonably believes that any payee is legally
incapable of giving a valid receipt and discharge for any payment due him, the Plan Administrator 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 therefor 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. 
 8.12 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 14.2, the benefits payable to such Alternate Payee shall be distributed pursuant to such qualified domestic relations order under
rules or procedures described by the Plan Administrator. If permitted by applicable law and regulations, the Plan Administrator may require or permit immediate distribution of such benefits to an Alternate Payee at any time following the
determination by the Plan Administrator that such 

  

 58 

 
an order is a qualified domestic relations order. In the event that an 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. 
 8.13 Additional Documents. 
 (a) The Plan Administrator or Trustee, or both, may require (and rely upon) the execution and delivery of such documents, papers and receipts as the Plan Administrator 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 under this Article VIII. 
 (b) The Plan Administrator or the Trustee, or both, may, as a condition precedent to the payment of death benefits hereunder, require an
inheritance tax release and/or such security as the Plan Administrator or Trustee, or both, may deem appropriate as protection against possible liability for state or federal death taxes attributable to any death benefits. 
 8.14 Transfer of Distributed Company Stock—Right of First Refusal for SAIC and the Plan. 
 (a) Any Company Stock distributed from the Plan which is Class B Common stock shall be subject to a right of first refusal by Science
Applications International Corporation (“SAIC”). The terms and conditions of the right of first refusal shall be those applied to Class A Common stock by the SAIC’s certificate of incorporation, as in effect from time to time.

 (b) Any Company Stock distributed from the Plan, in addition to the right of first refusal imposed by the SAIC’s
certificate of incorporation, shall also be subject to a right of first refusal in favor of the Plan, subordinate to that of SAIC, the terms and conditions of which (except for the right being in favor of the Plan) shall be the same as the SAIC
right of first refusal, modified as necessary to comply with applicable Treasury regulations. 
 (c) In administering the
rights of first refusal with respect to such Company Stock, the rights shall be modified, as necessary, to comply with applicable Treasury regulations.

 (a) 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). However, no allocation or delegation under this Section 9.2(a) shall be effective until the person or persons to whom the responsibilities have been
allocated or delegated agree to assume the responsibilities. The term “trustee responsibilities” as used herein shall have the meaning set forth in ERISA section 405(c). The preceding provisions of this Section 9.2(a) shall not
limit the authority of the Plan Administrator to appoint one or more Investment Managers in accordance with Section 9.3: 
 (b) To designate agents to carry out responsibilities relating to the Plan, other than fiduciary responsibilities. 
 (c) 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

 (i) To satisfy accounting, auditing, record keeping,
insurance, bonding and reporting and disclosure requirements. 
 (j) 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
Plan Administrator in the exercise of authority conferred upon it by this Plan shall be conclusive and binding upon the Participants and their Beneficiaries and any Alternate Payees. All discretionary powers conferred upon the Plan Administrator
shall be absolute, but shall be exercised in a uniform and nondiscriminatory manner. 
  

 61

duties in accordance with applicable law and in particular in accordance with ERISA section 404(a)(1). 
 (c) 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 Plan Administrator 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 Plan Administrator in the documents governing the relationship between or among the Plan, the Company and the Investment Manager. 
 9.4 Periodic Review. 
 (a) At periodic intervals, not less frequently than annually, the Plan Administrator shall review the long-run and short-run financial needs of the Plan and shall determine a funding policy for the Plan consistent with the objectives of the
Plan and the minimum funding standards of ERISA, if applicable. In determining the funding policy, the Plan Administrator shall take into account, at a minimum, not only the long-term investment objectives of the Trust Fund consistent with the
prudent management of the assets thereof, but also the short-run needs of the Plan to pay benefits. 
 (b) All actions taken
by the Plan Administrator with respect to the funding policy of the Plan, including the reasons therefor, shall be fully reflected in the minutes of the Plan Administrator’s actions. 
 9.5 Reliance Upon Documents and Opinions. 
 (a) The Plan Administrator, 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 Plan Administrator, the Board of Directors, the Company and 

  

 62 

 
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 Plan Administrator, 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 Plan Administrator 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. 
 9.6 Requirement of Proof. The Plan Administrator 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. 
 9.7 Multiple Fiduciary Capacity. Any person or group of persons may serve in more than one fiduciary capacity with respect to the Plan.

 9.8 Limitation on Liability. 
 (a) Except as provided in Part 4 of Title I of ERISA, neither the Company, the Board of Directors (or any member thereof), nor the Plan Administrator shall be subject to any liability with respect to his duties under
the Plan unless he or it acts fraudulently or in bad faith. 
 (b) Neither the Company, the Board of Directors (or any member
thereof) nor the Plan Administrator shall be liable for any breach of fiduciary responsibility resulting from the act or omission of any other fiduciary or any person to whom fiduciary responsibilities have been allocated or delegated, except as
provided in Part 4 of Title I of ERISA. 
 (c) Neither the Company, the Board of Directors (or any member thereof), the Plan
Administrator, nor the Trustee shall be liable to the extent relief from liability is provided pursuant to ERISA section 404(c). 
  

 63 

 (d) The Company in this Plan document does not intend to create additional fiduciary
liability, or to characterize actions or responsibilities as fiduciary in nature, beyond that required by ERISA or other applicable law. 
 9.9 Indemnification. 
 (a) To the extent permitted by law, the Company hereby indemnifies each member
of the Board of Directors, and any 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.

 (b) The preceding right of indemnification shall be in addition to any other right to which the Board of Directors or other
person may be entitled as a matter of law or otherwise. 
 9.10 Allocation of Fiduciary Responsibility. 
 (a) ERISA section 405(c) permits the division, allocation and delegation among Plan fiduciaries of the fiduciary responsibilities
owed to the Plan Participants and Beneficiaries. Under this concept, each fiduciary, including a Named Fiduciary, is accountable only for its own functions, except to the extent of his co-fiduciary liability under ERISA section 405. It is the
intent of the Company in establishing this Plan to comply with Section 405(c) and to have the limitation on liability set forth in ERISA section 405(c)(2) apply to the maximum extent allowed by law. 
 (b) Pursuant to ERISA section 405(c), the authority to control and manage the operation and administration of the Plan is allocated
to the Plan Administrator. Except to the extent expressly provided to the contrary in this Plan document, and the Trust Agreement, the responsibilities allocated to the Plan Administrator include: 
 (i) Responsibilities identified as Plan Administrator authority and powers in Sections 9.2(a) - (j); and 
 (ii) Responsibilities identified elsewhere in this Plan document as applicable to the Plan Administrator. 
  

 64 

 (c) The Board of Directors is allocated the following responsibilities, acting with the
advice and assistance of the Plan Administrator: 
 (i) Appointing the Trustee; 
 (ii) Adopting Plan amendments; 
 (iii) Determining the amount of Company Contributions; 
 (iv) Determining whether to
terminate the Plan or suspend contributions thereto; 
 (v) Determining which Affiliated Companies shall participate in the
Plan, and the conditions on which any such Affiliated Company shall participate; 
 (vi) Determining the form of Company
Contributions; and 
 (vii) Performing those duties specifically allocated to it elsewhere in this Plan document. 

(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 ERISA section 405(c), which may not legally be allocated to another person or fiduciary. Any Investment Manager appointed pursuant to Section 9.3 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. 
 9.11 Prohibition Against Certain Actions. 
 (a) To the extent prohibited by law, in administering this Plan the Plan Administrator shall not discriminate in favor of any class of
Employees and particularly it shall not discriminate in favor of Highly Compensated Employees. 
 (b) The Plan Administrator
shall not cause the Plan to engage in any transaction that constitutes a nonexempt prohibited transaction under Code section 4975(c) or ERISA section 406(a). 
 (c) All individuals who are fiduciaries with respect to the Plan (as defined in ERISA section 3(21)) shall discharge 

  

 65 

 
their fiduciary duties in accordance with applicable law, and in particular, in accordance with the standards of conduct contained in ERISA section 404.

 9.12 Bonding and Insurance. 
 (a) Except as provided in ERISA section 412, as may be required under any other applicable law, or as may be required by the Plan Administrator in its sole discretion, no bond or other security shall be required
by any member of any fiduciary under this Plan. 
 (b) For purposes of satisfying its indemnity obligations under
Section 9.9, the Company may (but need not) purchase and pay premiums for one or more policies of insurance. However, this insurance shall not release the Company of its liability under the indemnification provisions. 
 9.13 Voting and Other Rights of Company Stock. 
 (a) All voting rights of Company 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 9.13, Beneficiaries and Alternate Payees having an
interest in an Account or fund holding Company Stock) shall be given the opportunity to instruct the Trustee confidentially on a form prescribed and provided by the Company as to how to vote those shares (including fractional shares) of Company
Stock allocated to his Account(s) under the Plan (directly or indirectly through an interest in a Company Stock fund) on the date immediately preceding the record date for the meeting of shareholders of the Company. The Trustee shall not divulge to
the Company the instructions of any Qualified Holder. The Company may require verification of the Trustee’s compliance with such confidential voting instructions by an independent auditor elected by the Company. 
 (ii) All Participants entitled to direct such voting shall be notified by the Plan Administrator (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 of federal law) before these rights are to be
exercised. The notification shall include all information distributed by the Company to other shareholders regarding the exercise of such rights. 
  

 66 

 (iii) The Participants shall be so entitled to direct the voting of fractional shares (or
fractional rights to shares). However, the Plan Administrator 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 Qualified Holders
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 allocated to his Account, then these voting rights, together with voting rights as to shares of Company Stock which have not
been allocated, shall be exercised by the Trustee in the same proportion as the number of shares of Company 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. 
 (v) Except as provided in paragraph (b) below, all rights (other than voting rights) of Company 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, subject to the rules prescribed by the Plan Administrator, 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 Qualified Holders.
The Trustee shall have no discretion with respect to the exercise of any such rights. 
 (vi) Neither the Plan Administrator
nor the Trustee shall make any recommendation to any Qualified Holder regarding the exercise of the Participant’s voting rights or any other rights under the provisions of this Section 9.13, nor shall the Plan Administrator 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 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 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 Company Stock,
and the Trustee shall respond in accordance with the instructions so received. The Trustee shall 

  

 67 

 
not divulge to the Company the instructions of any Participant. The Plan Administrator 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. 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 with respect to which such Participant has the right of direction, and the Trustee shall have no discretion in such matter. 
 (ii) Unallocated shares of Company Stock and shares of Company 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 paragraph (i) above are tendered or exchanged, and the Trustee shall have no discretion in such matter.

 9.14 Plan Expenses. 
 (a) Except as provided in Section 9.14(b), all expenses incurred in the establishment, administration and operation of the Plan, 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 VI. 
 (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 Plan Administrator,
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 Plan Administrator. 
  

 68 

 ARTICLE X 
 MERGER OF COMPANY: MERGER OF PLAN 
 10.1 Effect of Reorganization or Transfer of
Assets. 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. 
 10.2 Merger Restriction. 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). 
  

 69 

 ARTICLE XI 
 PLAN TERMINATION AND 
 DISCONTINUANCE OF CONTRIBUTIONS 
 11.1 Plan Termination. 
 (a) Subject to the following provisions of this Section 11.1, the Company may terminate the Plan and the Trust agreements at any time and for any reason by an instrument in writing executed in the name of the Company by an officer or
officers duly authorized to execute such an instrument, and delivered to the Trustee. The Company expressly disavows any contractual obligation, implied or otherwise, to continue this Plan. 
 (b) The Plan and Trust agreements may terminate if the Company merges into any other corporation, if as a result of the merger the entity
of the Company ceases, and the Plan is terminated pursuant to the rules of Section 10.1. 
 (c) Upon and after the
effective date of the termination, the Company shall make no further contributions under the Plan and no contributions need be made by the Company applicable to the Plan Year in which the termination occurs, except as may otherwise be required by
law. 
 (d) The rights of all affected Participants to benefits accrued to the date of termination of the Plan, to the extent
funded as of the date of termination, shall automatically become fully vested as of that date. 
 11.2 Discontinuance of
Contributions. 
 (a) The Company by resolution of its Board of Directors may discontinue contributions to the Plan at
any time and for any reason in the Board’s sole discretion. Upon and after the effective date of this discontinuance, the Company shall make no further Company contributions under the Plan and no Company contributions need be made by the
Company with respect to the Plan Year in which the discontinuance occurs, except as may otherwise be required by law. 
  

 70 

 (b) The discontinuance of Company contributions on the part of the Company shall not
terminate the Plan as to the funds and assets then held by the Trustee, or operate to accelerate any payments of distributions to or for the benefit of Participants, Beneficiaries or Alternate Payees, and the Trustee shall continue to administer the
Trust Fund in accordance with the provisions of the Plan until all of the obligations under the Plan shall have been discharged and satisfied. 
 (c) However, if this discontinuance of Company contributions shall cause the Plan to lose its status as a qualified plan under Code section 401(a), the Plan shall be terminated in accordance with the provisions
of this Article XI. 
 (d) On and after the effective date of a discontinuance of Company contributions, the rights of
all affected participants to benefits accrued to that date, to the extent funded as of that date, shall automatically become fully vested as of that date. 
 11.3 Rights of Participants. In the event of the termination of the Plan, for any cause whatsoever, all assets of the Plan, after payment of expenses, shall be used for the exclusive benefit of
Participants and their Beneficiaries and no part thereof shall be returned to the Company, except as provided in Section 4.7 of this Plan or as otherwise permitted by law. 
 11.4 Trustee’s Duties on Termination. 
 (a) Upon termination of the Plan, the Plan Administrator 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) If so directed by the Plan Administrator upon termination of this Plan, the Trustee shall proceed as soon as possible to reduce all of the assets of the Trust Fund to cash and/or common stock and other securities in such proportions as
the Plan Administrator shall determine (after approval by the Internal Revenue Service, if necessary or desirable, with respect to any portion of the assets of the Trust Fund held in common stock or securities of the Company). After first deducting
the estimated expenses for liquidation and distribution chargeable to the Trust Fund, and after setting aside a reasonable reserve for expenses and liabilities (absolute or contingent) of the Trust, the Plan Administrator shall make the allocations
required under Article VI, where applicable, with the same effect as though the date of completion of liquidation were an Anniversary Date of the 

  

 71 

 
Plan. Following these allocations, the Trustee shall promptly, after receipt of appropriate instructions from the Plan Administrator, distribute in
accordance with such instructions to each former Participant, or Beneficiary or Alternate Payee, a benefit equal to the amount credited to his Accounts as of the date of completion of the liquidation. 
 (c) The Trustee and the Plan Administrator 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. 
 11.5 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 Plan Administrator and the Trustee shall follow
the same procedures and take the same actions prescribed in this Article XI in the case of a total termination of the Plan. 
 11.6
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.

 ARTICLE XII 
 APPLICATION FOR BENEFITS 
 12.1 Application for Benefits; Claims Procedure. The Plan
Administrator may require any person claiming benefits under the Plan to submit an application therefor, together with such documents and information as the Plan Administrator may require. In the case of any person suffering from a disability which

perfection of the application (together with an explanation why the material or information is necessary); and 
 (iii) An
explanation of the Plan’s claim review procedure. 
 (c) A claimant who wishes to contest the denial of his application
for benefits or to contest the amount of benefits payable to him shall follow the procedures for an appeal of benefits as set forth in Section 12.3 below, and shall exhaust such administrative procedures prior to seeking any other form of
relief. 
 12.3 Appeals. 
 (a)(i) A claimant who does not agree with the decision rendered with respect to his application may appeal the decision to the Plan Administrator. 
  

 73 

 (ii) The appeal shall be made, in writing, within sixty-five (65) days after the

 (c) The decision of the Plan
Administrator shall be made promptly, and not later than sixty (60) days after the Plan Administrator’s receipt of a request for review, unless special circumstances require an extension of time for processing, in which case a decision
shall be rendered as soon as possible, but not later than one hundred twenty (120) days after receipt of a request for review.

 74 

 ARTICLE XIII 
 LIMITATIONS ON ANNUAL ADDITIONS 
 13.1 Maximum Annual Additions. The Annual Additions
of a Participant shall not exceed the maximum permissible amount specified in Code section 415(c)(1). To the extent necessary to reduce an excess amount in a Participant’s Accounts, the Plan Administrator may distribute such
Participant’s Elective Deferrals to the Participant. Any such amounts shall be disregarded for purposes of the nondiscrimination test in Section 5.2 of the Plan and for purposes of determining whether the Participant has any Excess
Deferrals for the Plan Year. 
 13.2 Effect of Participation in Other Company Plans. 
 If a Participant in this Plan is also a Participant in another defined contribution plan maintained by the Company, the aggregate Annual Additions of the
Participant under this Plan and such other plan(s) shall not exceed the maximum permissible amount specified in Code section 415(c)(1). The Plan Administrator shall prescribe such rules as may be necessary or appropriate with respect to
applying this limit to the respective plans involved so as to ensure that the aggregate limit or Annual Additions is not exceeded. 
 13.3
Incorporation by Reference of Code Section 415. In order to ensure compliance with Code section 415, the Plan hereby incorporates said Section by reference as though it were set out as part of this Plan. In applying Code
section 415 to this Plan, the Plan shall include each grandfather or transition rule provided by such Section or any law amending such Section, in order to allow the largest benefit otherwise payable hereunder, or under other plans
maintained by the Company, to be paid. 
 13.4 No Contractual Right to Excess Contributions. If, in order to comply with the
limitations of this Article XIII, 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 Plan Administrator and
Trustee free of any contractual obligation to the Participant (or Beneficiary) affected based on prior Account balances or allocations. 
  

 75 

 ARTICLE XIV 
 RESTRICTION ON ALIENATION; PARTICIPANT LOANS 
 14.1 General Restrictions Against
Alienation. Except as otherwise provided by law and as otherwise provided by Sections 14.2 and 14.3: 
 (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. 
 (b) In the event any person attempts to take any action contrary to this Article XIV,
that action shall be void and the Company, the Plan Administrator, 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 14.1 shall be interpreted and applied by the Plan Administrator in
accordance with the requirements of Code section 401(a)(13) as construed and interpreted by authoritative judicial and administrative rulings and regulations. 
 14.2 Nonconforming Distributions Under Court Order. Benefits shall be paid to an Alternate Payee if such payment is required pursuant to a qualified domestic relations order, as defined in Code
sections 401(a)(13) and 414(p). 
 In the event that the Plan receives a domestic relations order, the Plan Administrator or its
delegate shall promptly 

  

 76 

 
notify the Participant and any Alternate Payee (i.e., spouse, former spouse, child or other dependent of a participant who is recognized by a domestic
relations order as having a right to receive all, or a portion of, the benefits payable under the Plan with respect to such Participant) of the receipt of such order and the Plan’s procedures for determining the qualified status of such orders,
and within a reasonable period of time after receipt of such order, the Plan Administrator shall determine whether such order is a qualified domestic relations order and notify the Participant and each Alternate Payee of such determination. In
determining the qualified status of a domestic relations order and in administering distributions under such qualified orders, the Plan Administrator shall follow the following procedures: 
 (a) When the Plan receives a domestic relations order affecting Plan benefits, the Plan Administrator or its delegate shall promptly
notify each person specified in the order as entitled to benefits under the Plan (using the address(es) included in the domestic relations order) of the Plan procedure as set forth herein (and as supplemented, if necessary, by Plan Administrator
procedures). 
 (b) The Plan shall permit an Alternate Payee to designate a representative for receipt of copies of notices
that are sent to the Alternate Payee with respect to a domestic relations order. 
 (c) The Plan Administrator shall review
any domestic relations order to determine if it satisfies the requirements of being a qualified domestic relations order. In making such determination, the Plan Administrator may seek the advice of legal counsel to the Plan and may rely upon the
legal opinion of such counsel in determining the qualified status of domestic relations orders and appropriate measures to resist or implement such orders. The Plan Administrator may, but need not, enter an appearance on behalf of the Plan in the
domestic relations lawsuit, if any, and may pursue such legal remedies as may be desirable for resisting unqualified orders or in modifying proposed orders. 
 (d) During any period in which the issue of whether a domestic relations order is a qualified domestic relations order is being determined
by the Plan Administrator, by a court of competent jurisdiction, or otherwise, the Plan Administrator shall segregate in a separate account in the Plan or in an escrow account the amounts, if any, which would have been payable to the Alternate Payee
during such period if the order had been determined to be a qualified domestic relations order. If, within eighteen (18) months it is determined that the order is not a qualified domestic relations order or the issue as to 

  

 77 

 
whether such order is a qualified domestic relations order is not resolved, than the Plan Administrator shall pay the segregated amounts (plus any interest
thereon) to the person or persons who would have been entitled to such amounts if there had been no order. Any determination that an order is a qualified domestic relations order which is made after the close of the aforementioned eighteen
(18) month period shall be applied prospectively only, should there be any undistributed benefits of the Participant to which the order related. 
 (e) If the Plan Administrator or other fiduciary of the Plan acts in accordance with the foregoing procedures in treating a domestic relations order as being (or not being) a qualified domestic relations order or
taking action to segregate an account and ultimately make payment thereof in accordance with subparagraph (d) above, then the Plan’s obligations to the Participant and each Alternate Payee shall be discharged to the extent of any payment
made pursuant to such act. 
 14.3 Authorized Participant Loans. The Plan Administrator may authorize one loan from the Trust
Fund to Participants (including, for this purpose, Suspended Participants) pursuant to rules prescribed by the Plan Administrator, except with respect to Participants who formerly participated in the NNS 401(k) Plan. Such Participants who formerly
participated in the NNS 401(k) Plan will be permitted to maintain up to two loans if such loans are outstanding as of September 1, 1999, but after such loans are repaid, such Participants will only be entitled to one loan from the Trust Fund
pursuant to the rules prescribed by the Plan Administrator. These rules shall be designed to ensure that these Participant loans satisfy the requirements of Code sections 4975(d)(1), 72(p), and any other provision of law that is, or may become
applicable. These rules shall provide that: 
 (a) The loans are available to all Participants on a reasonably equivalent
basis. 
 (b) The loans are not made available to Highly Compensated Employees in amounts greater than the amounts made
available for other Employees. For this purpose, the rules prescribed by the Plan Administrator may restrict the amount of the loan to a percentage of the Participant’s Account balance or to use different percentages depending upon the amount
of the loan, provided the percentages are applicable to all Participants. The Plan Administrator may also prescribe rules pursuant to which the portion of an individual’s Account that is invested in Company Stock (or a fund within the Trust to
which Company Stock is allocated) may (or may not) be taken into account in determining the maximum loan he may obtain. 
  

 78 

 (c) The loans bear a reasonable rate of interest. 
 (d) The loans are adequately secured. For this purpose, the amount of the security must be at least equal to the amount of the loan. The
rules to be prescribed by the Plan Administrator may permit a Participant to use some or all of his interest under the Plan as security for the loan, provided that the Participant’s interest in his Accounts attributable to Company Stock may not
be used as collateral for a loan. 
 (e) 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 Accounts under the Plan, the Participant and his spouse, if any, must consent to the loan and the possible reduction in the Accounts in the event of a set-off of the loan against the
Account balances as a result of nonpayment of the loan. Such consent must be given in writing within a ninety-day period before the Plan Administrator makes the loan. In the event the Participant defaults on the loan and Participant’s Accounts
are security for the loan, the Account 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
Accounts under the Plan. 
 (f) The loan must state the date upon which the loan must be repaid, which may not exceed five
years (except in the case of loans used to acquire a dwelling unit which, within a reasonable time after the loan is made, is to be used as the principal residence of the Participant). The loan must be repayable in substantially level payments, with
payments not less frequently than quarterly. However, if a Participant is on an approved, unpaid leave of absence, the loan repayments may be suspended for a period not longer than one year. In the case of this exception to the level payments
requirement, the loan must be repaid within the five year period and the remaining installment payments cannot be less than those required under the terms of the original loan. Notwithstanding the foregoing, loan repayments will be suspended under
this Plan as permitted under Section 414(u)(4) of the Code. 
 (g) In connection with the making of any loan to a
Participant pursuant to the provisions of this Section 14.3, the Participant receiving such a loan may be required to execute such documents as may be required by the Plan Administrator and/or Trustee. 
  

 79 

 (h) The amount of the loan may not exceed the lesser of: 
 (i) $50,000 (reduced by the excess of the highest outstanding balance of loans from the Plan during the one-year period ending on the date
preceding the date on which such loan is made); or 
 (ii) One-half of the present value of the Participant’s vested
interest in his Accounts. For purposes of this Section 14.3(h), the Participant’s vested interest and outstanding loan balances in all qualified employer plans (as such term is defined in Code section 72(p)(3)) of the Company shall be
aggregated to determine whether a loan shall be permissible hereunder and the maximum permissible amount thereof. 
 The decision as to
whether or not any Participant Loans shall be made under this Section 14.3 shall be made in the sole discretion of the Plan Administrator, and the Participant shall not have a contractual right to obtain a loan hereunder. 
 (i) In the event the Participant dies prior to distribution of his Distributable Benefit, the amount payable to his Beneficiary or spouse,
as applicable, shall be reduced by the amount of the security interest in the Participant’s vested interest held by the Plan by reason of a loan outstanding to such Participant. 
 (j) If a Participant is subject to the requirements of Section 8.6(a), a loan shall be granted to a Participant only if the
Participant obtains the consent of his spouse, if any, to use his Accounts as security for the loan. Spousal consent shall be obtained no earlier than the beginning of the 90-day period that ends on the date the loan is to be secured. The consent
must be in writing, must acknowledge the effect of the loan and must be witnessed by a plan representative or notary public. Such consent shall thereafter be binding with respect to the consenting spouse or any subsequent spouse with respect to that
loan. A new consent shall be required if the Participant’s Accounts are used for renegotiation, extension, renewal or other revision of the loan. 
  

 80 

 ARTICLE XV 
 PLAN AMENDMENTS 
 15.1 Amendments. The Board of Directors in its sole discretion may at
any time, and from time to time, amend the Plan by an instrument in writing executed in the name of the Company by an officer or officers duly authorized to execute such instrument, and delivered to the applicable Trustee. However, except as
provided in Section 15.2 no amendment shall be made at any time, the effect of which would be: 
 (a) To cause any assets
of the Trust Fund to be used for or diverted to purposes other than providing benefits to the Participants and their Beneficiaries, and defraying reasonable expenses of administering the Plan, except as provided in Section 4.7 or as otherwise
permitted by law; 
 (b) To have any retroactive effect so as to deprive any Participant or Beneficiary of any benefit to
which he would be entitled under this Plan if his employment were terminated immediately before the amendment; or 
 (c) To
increase the responsibilities or liabilities of a Trustee or an Investment Manager without its written consent. 
 15.2 Retroactive
Amendments. The Plan may be amended prospectively or retroactively (as provided in Code section 401(b)) to make the Plan conform to any provision of ERISA, any Code provisions dealing with tax-qualified employees’ trusts, or any
regulation under either. 
  

 81 

 ARTICLE XVI 
 TOP-HEAVY PROVISIONS 
 16.1 Application. If the Plan is or becomes top heavy in any
Plan Year, the provisions of this Article XVI will supersede any conflicting provisions in the Plan. 
 16.2 Criteria. The
Plan shall be top heavy for any Plan Year if any of the following conditions exist: 
 (a) The Top-Heavy Ratio for the Plan
exceeds 60% and this Plan is not part of any Required Aggregation Group or Permissive Aggregation Group of Plans. 
 (b) This
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%. 
 (c) This Plan is a 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%. 
 16.3 Definitions. For purposes of this Article XVI, the following terms
shall have the following meanings: 
 (a) Determination Date: With respect to any Plan Year, (i) the Determination Date
shall be the last day of the preceding Plan Year, or (ii) in the case of the first Plan Year of the Plan, the last day of such Plan Year. 
 (b) 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: 
 (i) An officer of the Company having an annual Compensation greater than 50% of the dollar limitation under Code
section 415(b)(1)(A); 
 (ii) 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; 
 (iii) A 5% Owner of the Company; or 
 (iv) A 1% Owner of the Company having annual Compensation from the Company of more than $150,000. 
  

 82 

 The determination period is the Plan Year containing the Determination Date and the four preceding Plan Years.

 (c) Permissive Aggregate 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 Aggregate Group. 
 (d) 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 determination period (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.

 (e) Top-Heavy Ratio: 
 (i) 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 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. 
 (ii) 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 

  

 83 

 
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). 
 (iii) For purposes of (i) and (ii) 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 12-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. 
 (iv) 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. 
  

 84 

 (f) Valuation Date: The date described in Section 2.1 as of which Account balances
or accrued benefits are valued for purposes of calculating the Top-Heavy Ratio. 
 16.4 Adjustment to Fractions. In any Plan
Year in which the Plan is Top-Heavy, in applying the limitations of Code section 415, the denominator of the Defined Benefit Fraction shall be computed using 100% of the dollar limitation instead of 125%, and the maximum aggregate amount used
with respect to the denominator of the Defined Contribution Fraction shall be computed by using 100% of the dollar limitation instead of 125%. 
 16.5 Vesting Requirements. If the Plan is determined to be a Top-Heavy Plan in any Plan Year, then a Participant’s right 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
Article VII 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 five or more years of vesting service
shall be given the option of remaining under the vesting schedule set forth above. 
 16.6 Minimum Contribution. If this Plan
is a Top-Heavy Plan 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 (a) under the Plan or (b) if the Plan is part of an Aggregation
Group, under any defined contribution plan in such Group. The percentage of compensation at which Company Contributions are made for a Key Employee shall be computed 

  

 85 

 
without regard to compensation in excess of the ceiling on includable compensation set forth in Section 16.7 of this Article XVI. For Plan Years
beginning before January 1, 1989, for purposes of this Section 16.6, 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 16.6. 
 l6.7 Ceiling on Includable Compensation. If this Plan is determined to be a Top-Heavy Plan in any Plan
Year, then only the first $150,000 of a Participant’s Compensation shall be taken into account in determining the allocation to the Accounts of such Participant for the Plan Year. The $150,000 limit shall automatically be adjusted for such Plan
Years and to such extent as is permitted by the Secretary of the Treasury. 
  

 86 

 ARTICLE XVII 
 MISCELLANEOUS 
 17.1 No Enlargement of Employee Rights.

applicable state unclaimed property or similar fund, pursuant to applicable state law. 
 (iv) The Plan Administrator shall
prescribe such rules as it may deem necessary or appropriate with respect to the notice, deposit or forfeiture rules stated above. 
 (e) 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 Plan Administrator shall prescribe rules that are consistent with the applicable provisions of the Code and/or ERISA.

or any other applicable law. 
 17.6 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 State of Virginia. All contributions made hereunder shall be deemed to have been made in Virginia.

sentence of Section 1.1 is amended to read as follows: 
 This document amends and restates the Plan in its entirety,
effective as of January 1, 1997, except where a different date is specifically provided.

 (a) For purposes of determining the allocation of Profit
Sharing Contributions pursuant to Sections 4.3 and 6.10(e) and the amount of the Participant’s permissible Elective Deferrals under Section 5.2, “Compensation” shall mean the amounts described in subsection (b) below paid by
the Company during a Plan Year by reason of services performed by an Employee less any compensation paid by reason of services performed during any period in which the Employee is not a Participant under this Plan, but including any elective
contributions that are made by the Company on behalf of an Employee pursuant to an arrangement described in Code sections 125, 132(f)(4), 402(a)(8), 402(h) or 403(b). 
 (b) For purposes of applying the limitation on Annual Additions pursuant to Article XIII of the Plan, “Compensation” shall mean
a Participant’s earned income, wages, salaries and fees for professional services and other amounts received for personal services actually rendered in the course of 

  

 -1- 

 
employment with the Company (including, but not limited to, commissions paid salespersons, compensation for services on the basis of a percentage of profits,
commissions on insurance premiums, tips and bonuses), and excluding the following: 
 (i) Company contributions to a plan of
deferred compensation that are not includable in the Employee’s gross income for the taxable year in which contributed, or Company contributions under a simplified employee pension (within the meaning of Code section 408(k)) to the extent such
contributions are excludable from gross income by the Employee, or any distributions from a plan of deferred compensation;

 (iv) Other amounts that received special tax benefits, or Company contributions (whether or not under a salary reduction

 Notwithstanding the foregoing, effective for Plan Years beginning after December 31, 1997, “Compensation” for purposes of
this subsection 2.19(b) shall include Elective Deferrals under Code section 402(g)(3) and amounts contributed under Code sections 125 and 132(f)(4) by the Company at the Employee’s election that are not included in the Employee’s gross

Participant attains age 70-1/2. 
 In the case of a 5% Owner, the Required Payment Commencement Date shall be April 1

 4. Effective on and after April 1,
2002, Section 8.8 is amended to read as follows in its entirety: 
 8.8 Timing on Distributions. 
 (a) Required Distributions Under the Plan. The Participant’s ability to elect the form or timing of payment (or the
Beneficiary’s ability, in the event of the Participant’s death before the date on which distributions commence) shall be subject to the following rules: 
 (i) Distributable Benefit Under $5,000. Notwithstanding any other provision of the Plan, if the 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 as soon as practicable following the Participant’s termination of employment, receipt of notice of Participant’s death or such subsequent Valuation Date, whichever is applicable. 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. 
 (ii) Distributable Benefit Upon Termination of Employment. If the value of the Participant’s Distributable Benefit determined
as of the date the Participant terminates employment and at each subsequent Valuation Date exceeds $5,000 no distribution shall be made to the Participant without the Participant’s consent before the Participant attains Normal Retirement Age,
or distributions are made at the termination of the Plan. Unless the Participant elects to defer distribution to the extent authorized, payment shall be made or commence no later than sixty (60) days after the close of the Plan Year in which
(A) the Participant attains Normal Retirement Age or (B) the Participant terminates employment with the Company, whichever occurs later. The failure of a Participant to consent to a distribution prior to such time shall be deemed to be an
election to defer commencement of payment. In no event shall distributions to a Participant commence later than the Participant’s Required Payment Commencement Date. 
  

 -2- 

 (iii) Distributable Benefit Upon Death. If the Participant’s Distributable
Benefit determined as of the date of the Participant’s death and at each subsequent Valuation Date exceeds $5,000, distribution of the Participant’s entire benefit shall be completed to the Participant’s Designated Beneficiary or
estate, as applicable, by December 31 of the calendar year containing the fifth anniversary of the Participant’s death except to the extent that the Designated Beneficiary elects, prior to April 1, 2002, to receive distributions in
accordance with subparagraph (A) or (B) below. 
 (A) If any portion of the Participant’s benefits are payable
to a Designated Beneficiary, distributions may be made over the Life Expectancy of the Designated Beneficiary if distributions are made or commence on or before December 31 of the calendar year which immediately follows the calendar year in
which the Participant dies. Prior to April 1, 2002, the Designated Beneficiary may elect one of the annuity options described in Section 8.6. 
 (B) If the Designated Beneficiary is the Participant’s surviving spouse, the date distributions are required to be made or begin in accordance with subparagraph (A) above shall not be earlier than the later
of (1) December 31 of the calendar year immediately following the calendar year in which the Participant dies and (2) December 31 of the calendar year in which the Participant would have attained age seventy and one-half
(70-1/2). Prior to April 1, 2002, the Beneficiary may select from the annuity options described in Section 8.6. 
 (C) Distributable Benefit After Death. If the Participant dies after distributions under one of the annuity options have begun, the remaining payments shall continue to be distributed at least as rapidly as under the method of
distribution being used prior to the Participant’s death. 
 (iv) Distributable Benefit Upon Required Payment
Commencement Date. If the Participant elects to receive his or her interest as a single sum, such Participant’s entire Account(s) must be distributed no later than his Required Payment Commencement Date. If prior to April 1, 2002, the
Participant commenced receipt of his or her Distributable Benefit in a form other than a single sum, on or after the Required Payment Commencement Date distributions shall be made in accordance with Treasury regulation section 1.401(a)(9), including
the minimum distribution incidental benefit rules of section 1.401(a)(9)-2 as may be amended. 
 (v) Distributable Benefit
to Surviving Spouse. If the surviving spouse dies after the Participant, but before payments to the spouse begin, the above provisions shall apply as if the surviving spouse were the Participant. Any amount paid to a child of the Participant
shall be treated as if it had been paid to the surviving spouse if the amount becomes payable to the surviving spouse when the child reaches the age of majority. 
  

 -3- 

 (b) Commencement of Benefits. Notwithstanding the prior provisions of this Article
VIII to the contrary, a Participant’s Plan Account and Matching Account Balances shall not be distributable earlier than: 
 (i) termination of the Participant’s employment with the Company on or after the date he or she attains Normal Retirement Date or by reason of death; 
 (ii) a determination of Disability in accordance with Section 2.23; 
 (iii) termination of the Participant’s employment with the Company and Affiliated Companies for any reason other than those specified
in paragraph (i) above, but only if such termination constitutes a separation from service (within the meaning of Code section 401(k)(2)(B)(i)(I); 
 (iv) the Committee’s approval of the Participant’s application for a hardship or in-service withdrawal, but only to the extent provided in Section 8.7; 
 (v) in accordance with and to the limited extent provided in Sections 5.2(d) and 5.6(a); 
 (vi) if and to the extent permitted by Code section 401(k)(10) in connection with the Company’s disposition of corporate assets or a
subsidiary; and 
 (vii) the creation or recognition of an Alternate Payee’s right to all or a portion of a
Participant’s Plan and Matching Contribution Accounts under a domestic relations order which the Committee determines is a qualified domestic relations order as provided in Section 14.2, but only as to the portion which is payable to the
Alternate Payee.

 EGTRRA AMENDMENT TO 
 AMSEC EMPLOYEES 401(K) PROFIT SHARING PLAN 
  

	A.	AMENDMENT OF THE PLAN FOR EGTRRA 

  

	 	1.	Adoption and Effective Date of Amendment. This Amendment of the Plan is adopted to reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act
of 2001 (“EGTRRA”). This Amendment is intended as good faith compliance with the requirements of EGTRRA and is to be construed in accordance with EGTRRA and guidance issued thereunder. Except as otherwise provided, this Amendment shall be
effective as of January 1, 2002 and unless otherwise extended past the “sunset” or otherwise made permanent pursuant to EGTRRA, this amendment will expire as of December 31, 2010. 

  

	 	2.	Supersession of Inconsistent Provisions. This Amendment shall supersede the provisions of the Plan to the extent those provisions are inconsistent with the provisions
of this Amendment. 

  

	B.	SECTIONS 2.62. ROLLOVERS FROM OTHER PLANS 

 The Plan will accept a direct rollover of an eligible rollover distribution from a qualified plan described in Code sections 401(a) or 403(a), excluding after-tax employee contributions, from a qualified plan described in Code sections
401(a) or 403(a), from a qualified plan or annuity contract described in Code sections 403(a) or (b), excluding after-tax employee contributions, from an eligible plan under Code section 457(b) which is maintained by a state, political subdivision
of a state, or any agency or instrumentality of a state or political subdivision of a state, and from the portion of a distribution from an individual retirement account or annuity that is described in Code sections 408(a) or (b) funded exclusively
with a distribution from another retirement plan qualified under Code section 401(a), 403(a) or (b), or 457(b), and earnings thereon (also known as a conduit IRA) that is eligible to be rolled over and would otherwise be includible in gross income.

  

	C.	SECTIONS 8.2. DISTRIBUTION UPON SEVERANCE FROM EMPLOYMENT 

  

	 	1.	New Distributable Event. This amendment to Section 8.2 of the Plan is intended to reflect the elimination of the “same desk rule”. A Participant’s
elective deferrals, qualified nonelective contributions, qualified matching contributions, and earnings attributable to these contributions shall be distributed on account of the Participant’s severance from employment. However, such a
distribution shall be subject to the other provisions of the Plan regarding distributions, other than provisions that require a separation from service before such amounts may be distributed. 

  

	 	2.	Effective Date. This change to section 8.2 shall apply to Plan Years and Limitation Years beginning on and after January 1, 2002.

	D.	SECTION 8.7. DIRECT ROLLOVERS OF PLAN DISTRIBUTIONS 

  

	 	1.	Effective Date. This section shall apply to distributions made after December 31, 2001. 

  

	 	2.	Modification of definition of Eligible Retirement Plan. For purposes of the direct rollover provisions of section 8.7, the Plan is amended to add the following to the
end thereof as follows: 

 “An eligible retirement plan shall also mean an annuity contract described in Code section
403(b) and an eligible plan under Code section 457(b) which is maintained by the state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state and which agrees to separately account for
amounts transferred into such plan from this Plan. The definition of eligible retirement plan shall also apply in the case of a distribution to a surviving spouse, or to a spouse or former spouse who is the Alternate Payee under a qualified domestic
relations order, as defined in Code section 414(p).” 
  

	 	3.	Modification of definition of Eligible Rollover Distribution to include After-Tax Employee Contributions. For purposes of the direct rollover provision in section
8.7(b) of the Plan, a portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not includible in gross income. However, such portion may be
transferred only to an individual retirement account or annuity described in Code sections 408(a) or (b), or to a qualified defined contribution 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.

 A new subsection 8.8(c) is added to read as follows:

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)	Time And Manner Of Distribution. 

  

	 	A.	Required Payment Commencement Date. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the

birthdays in the Distribution Calendar Year. 

  

	 	3.	Required minimum distributions will be determined under this section 8.8(c)(ii)(C) beginning with the first Distribution Calendar Year and up to and including the Distribution

 7. A new Section 5.8 is added to the Plan to read as follows in its entirety:

 5.8 Special Contract Contributions. 
 (a) Amount of Special Contract Contributions. Effective on and after January 1, 2004, the Company or a Contributing Employer
may satisfy the fringe benefit obligations under the McNamara-O’Hara Service Contract Act by electing, with the approval of the Committee, to make a Special Contract Contribution to each SCA Eligible Employee (as defined below) under the Plan
who was for the Measuring Period in question performing duties as a wage-earning Employee of the Company or a Contributing Employer. The amount of Special Contract Contribution to be allocated to each SCA Eligible Employee shall be calculated in
accordance with the formula specified in 29 CFR §4.175 as follows: 
 (i) the SCA Eligible Employee’s fringe
benefit determination rate multiplied by the total hours worked under the SCA Contract by the SCA Eligible Employee during the Measuring Period (subject to any caps or limits which may be set forth in the McNamara-O’Hara Service Contract Act or
the SCA Contract); less 
 (ii) the total amount contributed during the Measuring Period by the contributor (as applicable,
the Company or a Contributing Employer) on behalf of such SCA Eligible Employee for health and welfare and/or pension contribution (including, but not limited to, the employer’s portion of contributions for medical, dental, disability, and life
insurance, sick leave and retirement savings, including matching contributions under this Plan). 
 (b) Multiple
Contracts. Notwithstanding the preceding Section 5.8(a) to the contrary, the allocation to an SCA Eligible Employee working on more than one SCA Contract during a Measuring Period may consist of the sum of multiple calculations under
(i) and (ii), above; however, each such calculation shall be aggregated 

  

 -2- 

 
and offset to the full extent permitted under the McNamara-O’Hara Service Contract Act or the SCA Contract. 
 (c) Timing. It is expected that contributions made by the Company or a Contributing Employer under Section 5.8(a) shall be
paid to the Trustee quarterly or at such other intervals as may be required under the McNamara-O’Hara Service Contract Act or a specific SCA Contract, but not less than annually. 
 (d) Definitions. 
 (i) SCA Eligible Employee. “SCA Eligible Employee” means a covered non-exempt Employee, as defined under the Fair Labor Standards Act, working on one or more SCA Contracts and who for the Measuring
Period, has a deficiency between (A) the health and welfare and/or pension contributions made by the Company or a Contributing Employer and (B) the Company or a Contributing Employer’s fringe benefit obligation under an SCA Contract.
Notwithstanding the forgoing to the contrary, if for a Measuring Period the Company or a Contributing Employer elects to fulfill its fringe benefit obligation under an SCA Contract by making hourly cash equivalent or differential payments to its
Employees, such Employees shall not qualify as SCA Eligible Employees for such Measuring Period. 
 (ii) SCA Contract.
“SCA Contract” means a contract under the McNamara-O’Hara Service Contract Act or any other contract where a fringe benefit obligation wage determination is established by federal or state law. 
 (iii) Measuring Period. “Measuring Period” means the time set forth by the Committee for calculating a Special Contract
Contribution. The Committee may, in its discretion, establish a separate Measuring Period for the Company and each Contributing Employer which elects to make a contribution described in Section 5.8(a). Notwithstanding the foregoing to the
contrary, under no circumstances may the Measuring Period established by the Committee extend beyond the time required under an SCA Contract for the payment of a fringe benefit obligation and/or pension contribution under the McNamara-O’Hara
Service Contract Act or a specific SCA Contract. 
 8. Subsection 6.10(c) is amended to read as follows in its entirety: 
 (c) In accordance with Section 4.3, the Company or any Contributing Employer may, with the approval of the Committee, make a separate
Profit Sharing Contribution on behalf of its eligible Participants. Any Company Contributions that constitute a Profit Sharing Contribution shall be allocated to the Company Contribution Account of each Participant who is performing duties as a
wage-earning Employee of the Company or a Contributing Employer on the last day of the Plan Year and for any Participant who dies, retires or becomes disabled during the Plan Year. 
 (i) Any Profit Sharing Contribution made by the Company shall be allocated to each Participant eligible to receive a share of such
contribution in the 

  

 -3- 

 
proportion that the Compensation paid to each such Participant during the Plan Year by the Company bears to the Compensation paid to all such Participants
employed by the Company; and 
 (ii) Any Profit Sharing Contribution made by a Contributing Employer shall be allocated to
each such Participant who is otherwise eligible to receive a share of such contribution in proportion that the Compensation paid to each such Participant during the Plan Year by the Contributing Employer bears to the Compensation paid to all such
Participants employed by the Contributing Employer. 
 (iii) Although a Participant may receive allocations from the Company
and one or more Contributing Employers, or from two or more Contributing Employers, during a Plan Year the same Compensation shall not be used by more than one Contributing Employer and the Company for allocations made to such Participant’s
Company Contribution Account. 
 9. The first paragraph of Section 14.3 is amended to read as follows in its entirety: 
 The Plan Administrator may authorize one loan from the Trust Fund to Participants (including, for this purpose, Suspended Participants)
pursuant to rules prescribed by the Plan Administrator, except with respect to (i) Participants who formerly participated in the NNS 401(k) Plan and (ii) Participants who formerly participated in the EMA 401(k) Plan. Participants who
formerly participated in the NNS 401(k) Plan will be permitted to maintain up to two loans if such loans are outstanding as of September 1, 1999, but after such loans are repaid, such Participants will only be entitled to one loan from the
Trust Fund pursuant to the rules prescribed by the Plan Administrator. Participants who formerly participated in the EMA 401(k) Plan will be permitted to maintain up to three loans but only if such loans are outstanding under the EMA 401(k) Plan as
of December 1, 2003 and such loans were subsequently rolled over to this Plan in accordance with Section 5.5. After all such EMA 401(k) Plan loans are repaid, such Participants will only be entitled to one loan from the Trust Fund pursuant
to the rules prescribed by the Plan Administrator. These rules shall be designed to ensure that all Participant loans satisfy the requirements of Code sections 4975(d)(1), 72(p), and any other provision of law that is, or may become applicable.
These rules shall provide that:

Stock may be bought or sold in accordance with the terms and conditions of the “limited market” as set forth in a prospectus prepared by Science Applications International Corporation or its ultimate parent corporation for the Plan. If

discretion, elects to conduct a transaction with respect to the assets of the Plan. If Company Stock is readily tradable on an established securities market (or is Preferred Stock convertible into Company Stock that is readily tradable on an
established securities market), then rules established by Science Applications International Corporation or its ultimate parent corporation may designate any or all business days as “Trade Dates;” however, in no event shall such Trade
Dates be set any less frequently than four predetermined times per calendar year (one each calendar quarter). 

 4. Subsection 8.3(b)(i) is amended to read as follows effective June 1, 2006 in its entirety:

 (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: 
 (A) Medical expenses that would be deductible under Code Section 213(d) (determined without regard to whether the expenses exceed
7.5% of adjusted gross income); 
 (B) Purchase of the principal residence for the Employee (excluding mortgage payments);

 (C) Payment of tuition and related education fees for the next twelve months of post-secondary education for the Employee
or the Employee’s spouse, children or dependents (as defined in Code Section 152, without regard to sections 152(b)(l), (b)(2) and (d)(i)(B)); 
 (D) The need to prevent the eviction from the Employee’s principal residence or foreclosure on the mortgage of the Employee’s principal residence;

a reason for permitting distribution under this section. 
 5. Section 8.6 is amended to read as follows effective June 1, 2006 in
its entirety: 
 8.6 Optional Forms of Payment. 
 (a) Form. Effective on and after October 1, 2004 with respect PCI Legacy Employees and effective on and after January 1,
2004 with respect to all other Participants distributions shall be in the form of a cash lump sum or a Direct Rollover, as set forth Section 8.7. For distribtuions made on and after June 1, 2006, a Participant who has attained age
59 1/2 may elect to receive the portion of
his or her Distributable Benefit invested in Company Stock in the form of (i) whole shares of Company Stock (plus cash for any fractional shares of Company Stock) or (ii) cash. The value of the amount distributed in the form of cash from
the portion of a Participant’s Distributable Benefit invested in Company Stock shall be the net proceeds at the sale of the Company Stock liquidated pending distribution, plus the cash attributable to a fractional share. 
 (b) Notice of Right to Receive Company Stock. The Committee shall notify the Participant in advance of making the distribution of
his right to elect distribution in the form of Company Stock upon reaching age 59 1/2. Upon being so notified the Participant shall have a reasonable period of time (at least fourteen days) in which
to elect to receive his Distributable Benefit in the form of a Company Stock distribution as calculated under Subsection (c) below. 

 
This election by the Participant shall be made in writing or as otherwise permitted by Section 17.4, 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 Subsection (c) below. 
 (c) Distribution of Company Stock. A Company Stock Distributable Benefit shall be governed by the following rules: 
 (i) The amount of such a distribution shall be the number of whole shares of Company Stock held in 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) If more than one class of Company Stock is available for distribution to a Participant, the Participant must receive substantially the same proportion of each such class of stock (“Pro Rata
Distribution”). The rule in the preceding sentence shall not apply to the extent that the Participant elects, pursuant to rules to be prescribed by Science Applications International Corporation or its ultimate parent corporation, to receive
the distribution in a form other than the Pro Rata Distribution. For purposes of the foregoing, Preferred Stock is not considered available for distribution because Preferred Stock is converted prior to distribution. 
 (iii) Notwithstanding paragraphs (i) and (ii) above, a Company Stock Distributable Benefit shall not include Preferred Stock.
Instead, any such Preferred Stock shall be converted prior to distribution in accordance with the provisions of the applicable Certificate of Incorporation. 

 AMSEC EMPLOYEES 401(k) PROFIT SHARING PLAN 
 Amendment No. 10 
 The AMSEC
Employees 401(k) Profit Sharing Plan is hereby amended effective on and after January 1, 2006 as follows: 
  

	 	1.	Section 2.18, defining Company Stock, is amended by adding the following to the end of the definition: 

 “Company Stock shall consist of the ‘Exchangeable Company Stock Subaccount,’ and the ‘Non-Exchangeable Company Stock
Subaccount.’ If, at the time it authorizes a contribution to the Plan in the form of Company Stock, the Board of Directors specifies that such Company Stock is subject to investment direction by Participants as provided in Section 4.6,
then such Company Stock shall be credited to the Exchangeable Company Stock Subaccount. Furthermore, if pursuant to rules established by the Committee under Section 4.6, a Participant directs that a portion of his Accounts (other than Company
Stock credited to the Non-Exchangeable Company Stock Subaccount) be invested in Company Stock, then the Company Stock credited as a result of such contributions (along with that portion of any loan repayments by such Participant credited as Company
Stock by reason of the Participant’s direction to invest Elective Deferrals in Company Stock) shall be credited to the Exchangeable Company Stock Subaccount. All other all Company Stock shall be credited to the Non-Exchangeable Company
Subaccount.” 
  

	 	2.	Section 4.6(a) is amended to read as follows: 

 “The Committee shall establish rules setting forth the extent to which Participants may determine the manner in which their Accounts (other than Company Stock credited to the Non-Exchangeable Company Stock Subaccount) may be invested.
Consistent with such rules, the Committee may establish a choice of investment alternatives from which each Participant may select in determining the manner in which the applicable portions of his Plan Accounts will be invested. The Committee shall
prescribe procedures for investment of amounts (other than Company Stock credited to the Non-Exchangeable Company Stock Subaccount) allocated to an Alternate Payee Account. To the extent permitted under rules established by the Committee, a
Participant may direct that Company Contributions (other than Company Stock credited to the Non-Exchangeable Company Stock Subaccount) be invested all or in part in a Company Stock fund within the Trust. Company Stock credited to the
Non-Exchangeable Company Stock Subaccount shall not be subject to the direction of investments by Participants except as provided in Section 4.6(g) with respect to Participants who are no longer Employees. Fifty percent (50%) of a
Participant’s Company Matching Contributions shall be invested in the Non-Exchangeable Company Stock Subaccount. Neither the Committee nor the 

 
Trustee shall cause such Company Stock to be invested other than as provided in Section 4.6(g).” 
  

	 	3.	The following new Section 4.6(g) is hereby added to the Plan: 

  

	 	“(g)	Non-Exchangeable Company Stock Subaccount. 

 Except for Company Stock credited to the Exchangeable Company Stock Subaccount, the Company’s contributions made in the form of Company Stock are made with the expectation and understanding that such contributions shall remain invested
in Company Stock until the Participant whose Account is credited with such Company Stock ceases to be an Employee, except to the extent that diversification is otherwise expressly permitted under this Plan. Accordingly, the Non-Exchangeable Company
Stock Subaccount shall be invested exclusively in Company Stock (subject only to the power to hold cash pending immediate distribution to Participants, Beneficiaries, and Alternate Payees), and until the Participant whose Account is credited with
such Company Stock ceases to be an Employee shall not be transferred to any other investment alternative, except as otherwise expressly provided in this Plan. Notwithstanding any other provisions of the Plan, no fiduciary (including but not limited
to the Committee and the Trustees) shall have the authority or duty to cause any Company Stock credited to the Non-Exchangeable Company Stock Subaccount to be invested other than in Company Stock (except for cash held pending immediate distribution
to Participants, Beneficiaries, or Alternate Payees).”

occurring on or about June 30, 2006 or any postponement thereof (and for no other Quarterly Trade Date), that amounts credited to the Non-Exchangeable Company Stock Account on the Participant’s behalf as of such Quarterly Trade Date be
invested all or in any part in an investment alternative offered under the Plan other than the Company Stock fund.”

distribution, as described above, is greater than $1,000, then such amount shall be paid as a direct rollover to an individual retirement plan designated by the Company unless the Participant elects, in the manner proscribed by the Company,
to either (i) have the mandatory distribution paid directly to an eligible retirement plan specified by the Participant as a direct rollover in accordance with Section 8.7 or (ii) to receive the mandatory distribution directly.

	 	2.	Section 8.8(a)(i) is amended to read as follows in its entirety: 

 (a)(i) Distributable Benefit Under $5,000. Notwithstanding any other provision of the Plan, if the 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 mandatory distribution of the entire value of the Participant’s Distributable Benefit
as a single sum distribution as soon as practicable following the Participant’s termination of employment, receipt of notice of Participant’s death or such subsequent Valuation Date, whichever is applicable. However, effective for
distributions occurring on and after March 28, 2005, if the amount of the mandatory distribution, as described above, is greater than $1,000, then such amount shall be paid as a direct rollover to an individual retirement plan designated by the
Company unless the Participant elects, in the manner prescribed by the Company, to either (i) have the mandatory distribution paid directly to an eligible retirement plan specified by the Participant as a direct rollover in accordance
with Section 8.7 or (ii) to receive the mandatory distribution directly. If the Participant’s Distributable Benefit is zero, the Participant shall be deemed to have received a distribution of his entire Distributable Benefit.
Distributions in accordance with this Section 8.8(a)(i) shall not require consent by the Participant or the Participant’s spouse.

immediately upon such notice. 
 Provided the conditions precedents set forth above are met in full, and subject to the dollar limitation on the amount of
Services PPD Development is obligated to provide 

  

 2 

 
hereunder, the Services to be provided by PPD Development shall be limited to providing the direct labor support (i.e., PPD personnel) for the following
tasks and activities:

 Notwithstanding anything herein to the contrary, PPD Development’s obligation to provide the Services shall be limited to providing direct labor support having a

other forms of compensation), employee benefits and overhead with respect to all employees providing direct labor support for the Services, all as determined by PPD in its reasonable discretion and in accordance with its accounting methods and
practices, (ii) the aggregate cost incurred by PPD for any independent contractors providing labor for the performance of the Services and (iii) any unreimbursed out-of-pocket expenses that PPD has incurred in connection with the performance of the

part. For clarity, the cost for clinical trial 

  

 3 

 
services performed under the MSA for the Qualitative Study shall be paid to PPD Development in cash and are not included in PPD’s obligation to provide
Services as stated in this Section 1.1. PPD Development shall provide Services in compliance with this Schedule 2, PPD Development’s Standard Operating Procedures (“SOPs”), and all applicable laws, rules, and regulations. SOPs are
subject to revision by PPD Development in which case PPD Development shall notify Accentia of such revision. The current SOPs for conducting and monitoring clinical trials are available for review upon request by Accentia.” 
 4. Section 2 of Schedule 2. The first sentence of Section 2 of Schedule 2 is hereby stricken and replaced in its entirety by the following two
sentences: 
 “Accentia shall reimburse PPD for all out-of-pocket expenses incurred in connection with the performance of Services, including, without
limitation, travel expenses, printing fees and other “pass through” expenses reasonably expected to be incurred in connection with performing the Services (collectively, the “Pass Through Costs”). Notwithstanding anything herein
to the contrary, PPD shall have no obligation to advance, pay for or finance the payment of grants or other payments to clinical trial sites or investigators participating in any Clinical Trial under agreements with such investigators or
otherwise.” 
 5. Option To Terminate Services. Accentia and PPD shall each have the option to terminate PPD and PPD
Development’s obligations under Section 9(a) and Schedule 2 of this Agreement (the “Option”), each in their sole and absolute discretion, at any time prior to 5 PM Eastern time on December 31, 2006 by delivering written notice thereof
(the “Termination Notice”) to the other party on or before December 31, 2006. The Termination Notice shall be delivered to the other party in accordance with Section 10(e) of this Agreement and the date on which it is deemed given and
received under Section 10(e) shall be the “Termination Date” for purposes of this Section 5. Upon termination by either party under this Section 5, Accentia shall pay PPD an amount in cash equal to the Fully-Loaded Cost through the
Termination Date plus any additional obligations that PPD has incurred in performing the Services that are not cancelable or terminable by PPD (the “Full Cash Payment”). Following the Termination Date, PPD shall send Accentia an invoice
for the Full Cash Payment, which shall be due and payable in full within ten (10) days of the date on which PPD sent such invoice to Accentia. Upon receipt by PPD of the Full Cash Payment, the term “Royalty Stream” as used in the Restated
Agreement shall mean Royalty Stream as defined in the Original Agreement. For clarification, upon receipt by PPD of the Full Cash Payment from Accentia, the royalty payable to PPD on the SinuNase Formation shall be reduced from 14% to 7%.

 6. Remaining Terms and Conditions of Agreement. Except as specifically amended herein, all other terms and conditions of the
Restated Agreement are in full force and effect, including, without limitation, the payment of the Royalty Stream as defined in Section 1(l) of the Restated Agreement.
