 ARTICLE I 

GENERAL 
 1.1
Plan Name and Purpose. Effective as of May 1, 2018, Enterprise Services LLC (the “Company”) established the Enterprise Services 401(k) Plan (the “Plan”). The Plan is intended to qualify under Code
Section 401(a), and with respect to the portion hereof intended to qualify as a qualified cash or deferred arrangement, to satisfy the requirements of Code Section 401(k), and with respect to the portion intended to qualify as an employee
stock ownership plan, to satisfy the requirements of Code Section 4975(e)(7). This Plan is intended to qualify as a profit-sharing plan under Code Section 401(a)(27)(B). 

1.2 The Separation. In connection with DXC Technology Company’s (“DXC”) spinoff of the legal
entities constituting its U.S. public sector (“USPS”) business, DXC underwent an internal reorganization and incorporated Ultra SC Inc., which was renamed Perspecta Inc. (“Perspecta”), as a wholly-owned subsidiary of DXC and
parent company of the Company. Pursuant to an Agreement and Plan of Merger dated as of October 11, 2017, the USPS business (including Perspecta and the Company) was spun-off on or around June 1, 2018
(the “Separation”) and was subsequently combined with Vencore Holding Corp. (“Vencore”) and KGS Holding Corp. (“KGS”), creating an independent, publicly traded corporation which owns and operates the legal entities
constituting the USPS business previously owned and operated by DXC (through its direct and indirect subsidiaries), as well as Vencore and KGS, which have become wholly owned subsidiaries of Perspecta. 

1.3 Transfer of Assets and Liabilities, Service Credit. In connection with the Separation and as described in that
certain Employee Matters Agreement by and between DXC and Perspecta, the Company established this Plan to be substantially similar to the DXC Technology Matched Asset Plan (“DXC MAP”). On or around May 1, 2018, certain active
employees (“USPS Participants”) had their account balances under the DXC MAP transferred to this Plan. The assets and liabilities attributable to these USPS Participants are transferred to this Plan in accordance with Code
Section 414(l) and ERISA Section 208. In accordance with the Employee Matters Agreement between DXC and Perspecta, the Plan shall recognize each USPS Participant’s full service history under the DXC MAP for purposes eligibility,
vesting and benefits hereunder. 
 1.4 Effective Date. The original effective date of the Plan is May 1,
2018.

2.63 Special Dividend. Upon the Separation, each holder of DXC Stock will receive a dividend of one share of Perspecta
Stock for every two shares of DXC Stock he or she owns on the record date. 
 2.64 Spouse (Surviving Spouse). The
person to whom a Participant is legally married at the first to occur of (i) the time benefits commence or (ii) the date of his death. A former spouse will be treated as the Spouse or Surviving Spouse and a current Spouse will not be
treated as a Spouse or Surviving Spouse to the extent provided under a qualified domestic relations order as described in Code Section 414(p). 

2.65 Stock. Common stock of Perspecta and shares of stock of Perspecta or of another corporation for which such
common stock shall be exchanged, whether through reorganization, recapitalization, stock split-up, combination of shares, merger, consolidation or other change in the corporate stock structure, which stock
shall constitute Qualifying Employer Securities. In certain contexts throughout the Plan, “Stock” may also mean common stock of DXC or of another corporation for which such common stock shall be exchanged, whether through reorganization,
recapitalization, stock split-up, combination of shares, merger, consolidation or other change in the corporate stock structure, which stock shall constitute Qualifying Employer Securities. 

2.66 Temporary Employee. Temporary Employees can be either temporary Full-Time Employees or temporary Part-Time
Employees. Temporary Full-Time Employees are scheduled to work at least 30 hours per week for a period not to exceed six months. Temporary Part-Time Employees are scheduled to work less than 30 hours per week, but at least 20 hours per week, for a
period not to exceed six months. 
 2.67 Top Paid Group. The top 20 percent of Employees who performed
services for a Participating Employer or an Affiliated Company during the applicable year, ranked according to the amount of Includable Compensation received from a Participating Employer or an Affiliated Company during such year. The determination
of the Top Paid Group shall be made on a Participating Employer by Participating Employer basis including all Affiliated Companies of each Participating Employer. Leased Employees within the meaning of Code Sections 414(n)(2) and 414(o)(2) shall be
considered Employees unless such Leased Employees are covered by a plan described in Code Section 414(n)(5) and are not covered in any qualified plan maintained by a Participating Employer or an Affiliated Company. Employees who are non-resident aliens and who received no earned income (within the meaning of Code Section 911(d)(2) from the Company or an Affiliated Company constituting United States source income within the meaning of Code
Section 861(a)(3)) shall not be treated as Employees. Additionally, for the purpose of determining the number of active Employees in any year, the following additional Employees shall also be excluded; however, such Employees shall still be
considered for the purpose of identifying the particular Employees in the Top Paid Group: 

  
 16 








 (a) Employees with less than six (6) months of service; 

(b) Employees who normally work less than 17  1⁄2 hours per week; 
 (c) Employees who normally work less than six (6) months during
a year; and 
 (d) Employees who have not yet attained age 21. 

In addition, if 90 percent or more of the Employees of a Participating Employer or an Affiliated Company are covered under
agreements the Secretary of Labor finds to be collective bargaining agreements between Employee representatives and a Participating Employer or an Affiliated Company and the Plan covers only Employees who are not covered under such agreements, then
Employees covered by such agreements shall be excluded from both the total number of active Employees as well as from the identification of particular Employees in the Top Paid Group. 

The foregoing exclusions set forth in this Section shall be applied on a uniform and consistent basis for all purposes for
which the Code Section 414(q) definition is applicable. 
 The determination of a
Top-Paid Group shall be made on a Participating Employer-by-Participating Employer basis provided such Participating Employer is
not in the Company’s controlled group as defined under the Code using only the Includable Compensation that such Employee received from the Participating Employer. 

2.68 Total and Permanent Disability. An individual shall be considered to be suffering from a Total
and Permanent Disability if the Committee determines that the individual is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment. An individual’s disabled status shall be

five (5) working-days’ notice; signed a non-compete agreement before working outside of the Company; and any such work outside of the Company during this period was not for a competitor of the
Company, as determined by the Committee. 
 2.75 Year of Service. Except as provided in Appendices A and B,
“Year of Service” for a regular full-time Employee, shall mean for all purposes of this Plan, three hundred sixty-five (365) days of Service. For purposes of determining the Vested Interest of a part-time, casual or temporary
Employee, a Year of Service shall be calculated in the same manner as it is for a regular full-time Employee.

 ARTICLE III 

ELIGIBILITY AND PARTICIPATION 

3.1 Eligibility to Participate. Except as provided in Section 3.2, 

(a) A regular full-time Eligible Employee will be eligible to participate in the Plan as of the date he attains age 21. 

(b) A part-time, casual or temporary Eligible Employee will be eligible to participate in the Plan as of the date he attains

 19 








 ARTICLE IV 

COMPENSATION DEFERRALS 

4.1 Compensation Deferral Agreement. 

(a) Each Eligible Employee who desires to have Compensation Deferral Contributions made on his behalf shall enter into a
Compensation deferral agreement with his Participating Employer to have a percentage (from 1% (one percent) to 50% (fifty percent) (but not to exceed 14% (fourteen percent) for Highly Compensated Employees of the Company and each Affiliated Company)
of his Compensation deferred for each payroll period for which such Compensation deferral agreement is in effect. Such percentage shall be a whole percentage of Compensation up to the maximum permissible dollar amount under the Plan. A Participating
Employer shall make Compensation Deferral Contributions on behalf of the Participant in accordance with subsection 5.1(a)(i). A Participant may elect to designate all or a part of his Compensation Deferral Contributions as Roth Contributions. Such
designation shall be prospective only and shall be made at the same time and in the same manner for making Compensation Deferral Contributions as prescribed by the Committee. A Participant may prospectively change the amount of his Compensation
Deferral Contributions that are designated as Roth Contributions in accordance with procedures established by the Committee. All elections made by a Participant to designate all or part of his Compensation Deferral Contributions as Roth
Contributions shall remain in force until they are changed or until the Participant ceases to be eligible to participate in the Plan. Unless the context otherwise indicates, a Roth Contribution will be treated as a “Compensation Deferral
Contribution” for all purposes under the Plan. 
 (b) The Compensation deferral agreement shall remain in effect
throughout that Plan Year and all subsequent Plan Years until such agreement is modified, revoked or terminated, pursuant to Section 4.3, or the Participant ceases to be an Eligible Employee. A Compensation deferral agreement shall be made in
such form and manner as the Committee shall prescribe or approve. 
 (c) All Participants who are eligible to make
Compensation Deferral Contributions under this Plan and who have attained age 50 before the close of the calendar year shall be eligible to enter into an agreement with a Participating Employer to make
Catch-up Contributions in a whole dollar amount in accordance with, and subject to the limitations of, Code Section 414(v); provided, however, no Catch-up
Contributions may be made in the first payroll period of the Plan Year in which a Participant attains age 50. Such Catch-up Contributions shall not be taken into account for purposes of the Plan implementing
the required limitations of Code Sections 402(g) and 415. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Code Section 401(k)(3), 401(k)(11), 401(k)(12), 410(b), or 416, as
applicable, by reason of the making of such Catch-up Contributions. Matching Contributions shall not be made with respect to amounts contributed as Catch-up
Contributions regardless of whether such amounts are later recharacterized as Compensation Deferral Contributions. A Participant’s Catch-up Contribution election shall remain in effect throughout the Plan
Year and all subsequent Plan Years until such election is modified, revoked or terminated, pursuant to Section 4.3, or the Participant ceases to be an Eligible Employee. Catch-up Contribution elections
shall be made in such form and manner as the Committee shall prescribe or approve. A Participant may elect to designate all or a part of his Catch-up Contributions as Roth
Catch-up Contributions. Unless the context otherwise indicates, a Roth Catch-up Contribution will be treated as a “Catch-up
Contribution” for all purposes under the Plan. 

  
 20 








 4.2 Automatic Enrollment. 

(a) Definitions. The following definitions shall apply with respect to the automatic contribution arrangement: 

(i) Automatic Enrollment Date. With respect to an Eligible Employee who is automatically enrolled in the automatic
contribution arrangement of the Plan, the date specified as the Eligible Employee’s Automatic Enrollment Date in subsection 4.2(b). 

(ii) Automatic Enrollment Participant. An Eligible Employee who becomes a Participant by being automatically enrolled in
the automatic contribution arrangement of the Plan and has Compensation Deferral Contributions made to the Plan on his behalf in the Automatic Percentage. 

(iii) Automatic Percentage. The percentage of Compensation contributed to the Plan as a Compensation Deferral
Contribution on behalf of an Automatic Enrollment Participant. 
 (b) Automatic Contribution Arrangement. An Eligible
Employee who is not a member of a union, who is eligible to participate in the Plan pursuant to Article 3, and who has not entered into a Compensation deferral agreement pursuant to Section 4.1 shall be automatically enrolled in the Plan and
shall have Compensation Deferral Contributions made on his behalf. Notwithstanding the foregoing, such Eligible Employee shall not be automatically enrolled in the Plan if, within 60 days of becoming eligible to participate in the Plan pursuant to
Article 3, the Eligible Employee affirmatively elects not to participate in the automatic contribution arrangement or the Eligible Employee enters into a Compensation deferral agreement to make Compensation Deferral Contributions in any amount
pursuant to Section 4.1. With respect to any Eligible Employee who becomes or again becomes eligible to participate in the Plan pursuant to Article 3, Compensation Deferral Contributions shall automatically be made beginning on the date of the
Eligible Employee’s first paycheck following the 60th day after the date the Eligible Employee becomes or again becomes eligible to participate in the Plan pursuant to Article 3, which date shall be that Eligible Employee’s Automatic
Enrollment Date. 

  
 21 








 (c) Automatic Contribution Arrangement Contributions. A Compensation
Deferral Contribution in the Automatic Percentage shall be made to each Automatic Enrollment Participant’s Account by the Participating Employer on behalf of each Automatic Enrollment Participant beginning on the Eligible Employee’s
Automatic Enrollment Date unless and until the Automatic Enrollment Participant affirmatively elects to cease being an Automatic Enrollment Participant by (i) affirmatively electing not to participate in the automatic contribution arrangement,
(ii) entering into a Compensation deferral agreement to make Compensation Deferral Contributions pursuant to Section 4.1, (iii) changing the percentage of Compensation Deferral Contributions pursuant to Section 4.3, or

	7%	  	Beginning on the fourth anniversary of the Automatic Enrollment Date and ending one calendar year thereafter
		
	8%	  	Beginning on the fifth anniversary of the Automatic Enrollment Date and ending one calendar year thereafter
		
	9%	  	Beginning on the sixth anniversary of the Automatic Enrollment Date and ending one calendar year thereafter
		
	10%	  	Beginning on the seventh anniversary of the Automatic Enrollment Date and continuing for each calendar year thereafter

 (e) Investments. Compensation Deferral Contributions made on behalf of an Automatic
Enrollment Participant shall be invested in the qualified default investment alternative fund designated by the Committee and specified in Appendix G to the Plan unless and until the Participant otherwise directs pursuant to Section 7.2. 

  
 22 








 4.3 Modification, Revocation or Termination of Compensation Deferral Agreement and Catch-up Contribution Elections. 
 (a) A Participant may change the percentage of
his Compensation Deferral Contributions or the amount of Catch-up Contributions during any payroll period by delivering to the Plan Administrator his written notice (or other means of communication, such as
telephonic or electronic, as the Plan Administrator may designate) of such change. Any such change shall become effective as soon as administratively feasible after receipt by the Plan Administrator to receive such changes. 

(b) A Participant may revoke his Compensation deferral agreement or Catch-up
Contribution election during any payroll period by delivering to the Plan Administrator his written notice (or other means of communication, such as telephonic or electronic, as the Plan Administrator may designate) of such revocation. Such
revocation shall become effective as soon as administratively feasible after receipt by the Committee. A revocation shall remain in effect throughout that Plan Year and all subsequent Plan Years until the Participant enters into a new Compensation
deferral agreement or Catch-up Contribution election with his Participating Employer pursuant to Section 4.1. 

(c) A Participant’s Compensation deferral agreement or Catch-up Contribution
election shall automatically terminate if he ceases to be an Eligible Employee. If he again becomes an Eligible Employee and desires again to defer a portion of his Compensation, it shall be his responsibility to enter into a new Compensation
deferral agreement or Catch-up Contribution election to resume Compensation deferrals or Catch-up Contributions. 

(d) The Committee may prescribe such rules as it deems necessary or appropriate regarding the modification, revocation or
termination of a Participant’s Compensation deferral agreement or Catch-up Contribution election. 

(e) It shall be the responsibility of an Eligible Employee who elects Compensation Deferral Contributions or Catch-up Contributions to be made to this Plan to verify that the amounts of Compensation deferrals or Catch-up Contributions are in accordance with his Compensation deferral
agreement or Catch-up Contribution election, and investment of such deferrals is in accordance with his investment designations. 

4.4 Amount Subject to Deferral. 

(a) No Participant shall be permitted to make Compensation Deferral Contributions or
Catch-up Contributions in any calendar year in excess of the amount as may be determined from time to time by the Secretary of the Treasury pursuant to Code Section 402(g) or 414(v), respectively. If a
Participant’s Compensation Deferral Contributions or Catch-up Contributions exceed the amount as determined in the previous sentence for any calendar year for any reason, such excess contributions
allocable thereto shall be returned to the Participant, as provided in Section 4.7. 

  
 23 








 (b) The Committee may prescribe such rules as it deems necessary or appropriate
regarding deferrals under subsection 4.1(a) or 4.1(c), including rules regarding the timing of a deferral election. These rules shall apply to all Employees eligible to enter into a Compensation deferral agreement or
Catch-up Contribution election described in Section 4.1. 
 4.5 Limitation on
Compensation Deferrals by Highly Compensated Employees. With respect to each Plan Year, Compensation Deferral Contributions (including amounts contributed pursuant to subsection 4.1(c) that are recharacterized as Compensation Deferral
Contributions) by Highly Compensated Employees under the Plan for the Plan Year shall not exceed the limitations on contributions by or on behalf of Highly Compensated Employees under Code Section 401(k), as provided in this Section. This
determination shall be made on the basis of the Company and its Affiliated Companies as one testing group and each Participating Employer, as defined under subsection 2.47(c) and its Affiliated Companies, each as a separate testing group. If
Compensation Deferral Contributions under this Plan by or on behalf of Highly Compensated Employees for any Plan Year exceed the limitations of this Section 4.5 for any reason, such excess contributions and any income allocable thereto shall be
returned to the Participant, as provided in Section 4.6. The Actual Deferral Percentage test will be calculated using the Current Year Testing method described in Treasury Regulations
Section 1.401(k)-2(a)(2). 
 (a) The Compensation Deferral Contributions by a
Participant who is a Highly Compensated Employee for a Plan Year shall satisfy one of the following tests: 
 (i) The Actual
Deferral Percentage for Eligible Employees who are Highly Compensated Employees shall not be more than the Actual Deferral Percentage of all other Eligible Employees multiplied by 1.25; or 

(ii) The excess of the Actual Deferral Percentage for Eligible Employees who are Highly Compensated Employees over the Actual
Deferral Percentage for all other Eligible Employees shall not be more than two percentage points, and the Actual Deferral Percentage for Highly Compensated Employees shall not be more than the Actual Deferral Percentage of all other Eligible
Employees multiplied by 2.00. 
 (b) For the purposes of this Article 4, “Actual Deferral Percentage” means, with
respect to Eligible Employees who are Highly Compensated Employees and all other Eligible Employees for a Plan Year, the average of the ratios, calculated separately for each Employee in such group, of the amount of Compensation Deferral
Contributions under the Plan on behalf of each Employee for such Plan Year to such Employee’s Includable Compensation for such Plan Year. 

(c) If as of the last day of a Plan Year this Plan satisfies the requirements of Code Section 401(a)(4) or 410(b) only if
aggregated with one or more other plans which include arrangements under Code Section 401(k), then this Section 4.5 shall be applied by determining the Actual Deferral Percentages of Eligible Employees as if all such plans were a single
plan. 

  
 24 








 (d) For the purposes of this Section 4.5, the Actual Deferral Percentage for
any Highly Compensated Employee who is a Participant under two or more Code Section 401(k) arrangements of a Participating Employer or an Affiliated Company shall be determined by taking into account the Highly Compensated Employee’s
Compensation (including any differential wage payment (as defined in Code Section 3401(h)(2)) made by a Participating Employer) under each such arrangement and contributions under each such arrangement which qualify for treatment under Code
Section 401(k). 
 (e) For purposes of this Section, the amount of Compensation Deferral Contributions by a Participant
who is not a Highly Compensated Employee for a Plan Year shall be reduced by any Compensation Deferral Contributions in excess of the limits under Code Section 402(g) (as adjusted upward by the Secretary of Treasury) which have been distributed
to the Participant under Section 4.7, in accordance with regulations prescribed by the Secretary of the Treasury under Code Section 401(k). 

(f) The determination and treatment of Compensation Deferral Contributions and the Actual Deferral Percentage of any
Participant shall satisfy such other requirements as may be prescribed by the Secretary of the Treasury. 
 4.6 Provisions for
Distribution of Excess Contributions by Highly Compensated Employees. The Committee shall determine, as soon as is reasonably possible following the close of each Plan Year the extent, if any, to which the Compensation Deferral
Contributions by Highly Compensated Employees do not satisfy one of the tests set forth in Section 4.5. Notwithstanding any other provision of the Plan, if Excess Contributions exist, the Committee shall distribute such Excess Contributions,
plus any income and minus any loss allocable thereto, no later than the last day of each Plan Year to Participants to whose Accounts such Excess Contributions were allocated for the preceding Plan Year. Excess Contributions are allocated to the
Highly Compensated Employees with the largest amounts of Compensation Deferral Contributions taken into account in calculating the Actual Deferral Percentage test for the year in which the excess arose, beginning with the Highly Compensated Employee
with the largest amount of such Compensation Deferral Contributions and continuing in descending order until all the Excess Contributions have been allocated. For purposes of the preceding sentence, the “largest amount” is determined after
distribution of any Excess Contributions. However, in determining the amount of Excess Contributions to be distributed with respect to an affected Highly Compensated Employee as determined herein, such amount shall be reduced by any Excess
Contributions previously distributed to such affected Highly Compensated Employee for his taxable year ending with or within such Plan Year. 

(a) With respect to the distribution of Excess Contributions such distribution: 

(i) shall be adjusted for income as provided in (c) below; and 

(ii) shall be designated by the Committee as a distribution of Excess Contributions (and income). 

(b) Any distribution of less than the entire amount of Excess Contributions shall be treated as a pro rata distribution of
Excess Contributions and income. 

  
 25 








 (c) Income Allocable to Excess Contributions. The income allocable to Excess
Contributions shall be equal to the allocable gain or loss for the Plan Year. In all events, the gain or loss allocable to Excess Contributions will be determined in accordance with Code Section 401(k) and the regulations issued thereunder.

 (d) If the correction of a Participant’s Excess Contributions requires the distribution of amounts from a
Participant’s Accounts, the distribution shall be removed from the accounts as determined by the Plan Administrator in its sole discretion. 

4.7 Provisions for Distribution of Annual Compensation Deferral Contributions in Excess of the Applicable Limit. 

(a) If the Compensation Deferral Contributions or Catch-up Contributions by a
Participant under this Plan and “elective deferrals” or catch-up contributions (as defined or described in Treasury Regulations Section 1.402(g)-1(b)) and
Code Section 414(v), respectively, under all other plans, contracts, or arrangements of a Participating Employer shall exceed the “applicable limit” (as defined in Treasury Regulations Sections
1.402(g)-l(d) and 1.402(g)-2) for the Participant’s taxable year, then such excess Compensation Deferral Contributions or
Catch-up Contributions and the income allocable to the excess Compensation Deferral Contributions and Catch-up Contributions shall be distributed to the Participant
(after withholding applicable federal, state and local income taxes due on such amounts) on or before the first April 15 following the close of the calendar year in which such excess contribution is made. The income allocable to excess
Compensation Deferral Contributions or Catch-up Contributions shall equal the sum of the gain or loss for the taxable year of the Participant. In all events, the income attributable to excess Compensation
Deferral Contributions or Catch-up Contributions will be determined in accordance with Code Section 402(g) and the regulations issued thereunder. The Committee shall not be liable to any Participant (or
his Beneficiary, if applicable) for any losses caused by incorrectly estimating the amount of any Participant’s Compensation Deferral Contributions or Catch-up Contributions in excess of the limitations
of this Article 4 and any income allocable to such excess. 
 (b) On or before April 1, a Participant may submit a claim
to the Committee in which he certifies in writing the specific amount of his Compensation Deferral Contributions or Catch-up Contributions for the preceding calendar year which, when added to amounts deferred
for such calendar year under other plans or arrangements described in Code Section 401(k), 408(k) or 403(b), will cause the Participant to exceed the “applicable limit” for the calendar year in which the deferral occurred.
Notwithstanding the amount of the Participant’s Compensation Deferral Contributions under the Plan for such preceding calendar year, the Committee shall treat the amount specified by the Participant in his claim as a Compensation Deferral
Contribution in excess of the “applicable limit” for such calendar year and return such excess, as adjusted for any income or loss allocable thereto, to the Participant as provided in (a) above. 

(c) Any excess Compensation Deferral Contributions shall be treated as Annual Additions under Article 15 for the Plan Year for
which the excess Compensation Deferral Contributions were made unless such excess is distributed to a Participant in accordance with this Section. 

  
 26 








 (d) If a distribution is required for a Participant’s contributions to
comply with an “applicable limit”, the distribution shall be removed from the accounts as determined by the Plan Administrator in its sole discretion. 

4.8 Character of Amounts Contributed as Compensation Deferrals. Amounts deferred pursuant to the Compensation
deferral agreement and Catch-up Contribution election described above in Section 4.1 (and which qualify for treatment under Code Section 401(k) and are contributed to the Trust Fund pursuant to
Article 6) shall be treated for federal and state income tax purposes, as Participating Employer Contributions. 
 4.9
Participant Voluntary Contributions. A Participant shall not be permitted to make any voluntary after-tax contributions to the Plan. 

4.10 Participant Rollover Contributions. 

(a) Effective as of a Participant’s Eligibility Date, or such later date as may be determined by the Committee, the
account, if any, of such Participant then held in trust under another plan that satisfies the requirements of Code Section 401(a), an annuity contract described in Code Section 403(b), or in an individual retirement account which is
attributable solely to a rollover contribution within the meaning of Code Section 408(d)(3)(A)(ii), may be transferred to this Plan and credited to the Participant’s Rollover Account in accordance with rules which the Committee shall
prescribe from time to time; provided, however, the Committee determines that the continued qualification of this Plan would not be adversely affected by such transfer. Except as provided in Appendix E, no individual shall be eligible to rollover
any amounts that are considered to be a loan under another plan. In the case of a transfer to this Plan of a Participant’s account under a plan of an Affiliated Company, such transfer shall be made directly from the trustee of the plan of such
Affiliated Company to the Trustee of this Plan. Any amount transferred in accordance with this Section 4.10 shall not be subject to distribution to the Participant except as expressly provided under the terms of this Plan. Any such rollover
under this Section 4.10 shall be made to the Plan in cash, except for those loans as provided in Appendix E. 
 (b) A
Participant may apply to the Committee to deposit a direct transfer from a designated Roth account under another applicable retirement plan, which shall be deposited into the Roth Rollover Account established or maintained under the Plan in the name
of the contributing Participant. The Committee shall, before agreeing to accept any such transfer, seek and obtain reasonable representations from the plan administrator or other responsible party of the distributing plan (i) of the first year
of the Five-Taxable-Year Period for the Participant and the portion of such distribution that is attributable to investment in the contract; or (ii) that the distribution is a Qualified Roth Distribution. The Plan shall not accept an indirect
(i.e., 60 day) transfer from a designated Roth account under another applicable retirement plan. 

  
 27 








 ARTICLE V 

EMPLOYER CONTRIBUTIONS 

5.1 Amount of Participating Employer Contributions. 

(a) Subject to the requirements and restrictions of this Article 5 and Articles 6 and 15, a Participating Employer shall make
contributions to the Plan as follows: 
 (i) As soon as administratively practicable following each payroll period, the
Participating Employer shall make a Compensation Deferral Contribution on behalf of a Participant equal to the amount of Compensation deferred by the Participant for each payroll period pursuant to the Compensation deferral agreement described in
subsection 4.1(a) hereunder, provided such Compensation Deferral Contribution qualifies for tax treatment under Code Section 401(k). Notwithstanding the foregoing, in no event shall such Compensation Deferral Contributions be contributed before
(i) the Participant has entered into a Compensation deferral agreement with a Participating Employer or (ii) the Participant’s performance of services that relate to the Compensation that, but for the Participant’s Compensation
deferral agreement, would have been paid to the Participant. 
 (ii) As soon as administratively practicable following each
payroll period, the Participating Employer shall make a Catch-up Contribution on behalf of a Participant equal to the amount of Compensation (determined without regard to subsection 2.11(f)) deferred by the
Participant for each payroll period ending within such calendar month pursuant to the Catch-up Contribution deferral agreement described in Section 4.1(c) hereunder, provided such Catch-up Contribution qualifies for tax treatment under Code Section 414(v). Notwithstanding the foregoing, in no event shall such Catch-up Contributions be contributed
before (i) the Participant has entered into an agreement with a Participating Employer to make Catch-up Contributions or (ii) the Participant’s performance of services that relate to the
Compensation that, but for the Participant’s Catch-up Contribution deferral agreement, would have been paid to the Participant. 

(iii) Except as otherwise provided in the Plan, including Appendix A thereto: 

(1) As soon as administratively practicable following the end of the Plan Year, the Participating Employer shall make a
Matching Contribution (which may include forfeitures applied pursuant to subsection 9.5(b)) on behalf of a Participant in an amount as follows: 

(A) For Compensation paid to employees, an amount equal to fifty percent (50%) of the first six percent (6%) of the aggregate
Compensation Deferral Contributions made on behalf of the Participant during the preceding Plan Year, provided the Participant’s aggregate Compensation Deferral Contributions qualify for tax treatment under Code Section 401(k). 

  
 28 








 (B) A Participant shall be eligible for such Matching Contribution on the date
the Participant commences participation in the Plan. Notwithstanding the foregoing, in no event shall such Matching Contributions be contributed before (i) the Participant has entered into a Compensation deferral agreement with a Participating
Employer or (ii) the Participant’s performance of services that relate to the Compensation that, but for the Participant’s Compensation deferral agreement, would have been paid to the Participant. For the avoidance of doubt,
Participants must be employed with a Participating Employer on December 31 of the Plan Year in order to receive a Matching Contribution under this subsection 5.1(a)(iii) with respect to such Plan Year. Participants who die or retire on or after
their Early Retirement Date or Normal Retirement Date will receive a Matching Contribution for the applicable Plan Year as soon as administratively practicable following the Participant’s date of death or retirement. Solely for purposes of
calculating the Matching Contribution for the 2018 Plan Year, a Participant’s aggregate Compensation Deferral Contributions shall include any compensation deferral contributions made under the DXC MAP. 

(2) Notwithstanding the foregoing, Matching Contributions provided under this Section 5.1(a)(iii) to Participants who are
collectively bargained employees shall be made as soon as administratively practicable following each payroll period. 
 (3)
For the avoidance of doubt, Compensation Deferral Contributions designated as Roth Contributions shall be included in the calculation of Matching Contributions. 

(b) In no event shall contributions made under subsection 5.1(a)(iii) above for any Plan Year be made later than the time
prescribed by law for the deduction of such contribution for purposes of a Participating Employer’s federal income tax, as determined by the applicable provisions of the Code. 

(c) Subject to the following, each Participating Employer may make annual Discretionary Employer Contributions, in cash, for
that Participating Employer’s fiscal year, which shall be allocated to each eligible Participant’s Discretionary Employer Contributions Account in a uniform percentage as determined by the Participating Employer, provided that such
percentage shall not exceed three percent (3%) of the Participant’s Compensation received during that fiscal year: 

  
 29 








 (i) The Discretionary Employer Contributions made pursuant to this Section shall
be made in a manner that is nondiscriminatory and that meets all of the applicable qualification requirements of the Code. 

(ii) In order to be eligible to receive Discretionary Employer Contributions, a Participant (A) must have been at least 50
years old on April 3, 2009, and must have been enrolled in and actively making employee contributions to the Computer Sciences Corporation Employee Pension Plan for the entire pay period that ended on April 3, 2009 (if the Participant was laid-off after April 3, 2009 and then re-employed, the Participant will not be eligible to receive Discretionary Employer Contributions unless the re-employment occurs on or before July 2, 2009), or (B) must have been on the payroll of CSC Applied Technologies LLC on April 3, 2009, or on the payroll of any entity within CSC Applied Technologies
LLC’s “controlled group” (within the meaning of Code Section 414, and regulations thereunder) on April 3, 2009. Notwithstanding the foregoing, the following Participants shall not be eligible to receive Discretionary
Employer Contributions: 
 (1) for periods prior to August 15, 2015, former employees of E.I. du Pont de Nemours and
Company who are covered by Supplement 1 of the Computer Sciences Corporation Employee Pension Plan. 
 (2) for periods prior
to January 5, 2013, former employees of Conoco Inc. who are covered by Supplement 2 of the Computer Sciences Corporation Employee Pension Plan, and 

(3) for periods prior to January 5, 2013, any employees who transferred from the United States government payroll in the
LogMod transaction (whether covered by Appendix K of the Computer Sciences Corporation Employee Pension Plan or by a non-Appendix K section of the Computer Sciences Corporation Employee Pension Plan). 

(iii) The Participating Employer may designate whether or not the Participant must be an active Employee on the last day of the
applicable fiscal year or on any particular day during such fiscal year, and/or at the time the Discretionary Employer Contribution is made, in order to be eligible for a share in the Discretionary Employer Contribution. 

(iv) Discretionary Employer Contributions shall be invested in accordance with each Participant’s investment election for
such amounts under Section 7.2. If no such election is made, the Discretionary Employer Contribution shall be invested in the Investment Funds otherwise elected by the Participant for investment of the Participant’s Compensation Deferral
Account. In the event a Participant has not designated an Investment Fund for the investment of his Compensation Deferral Account, any Discretionary Employer Contributions allocated to the Participant pursuant to this subsection 5.1(c) shall be
invested in the same qualified default investment alternative fund designated by the Committee and specified in Appendix G to the Plan for Compensation Deferral Contributions made on behalf of Automatic Enrollment Participants, unless and until the
Participant otherwise directs pursuant to Section 7.2. 

  
 30 








 (v) In no event shall a Participating Employer be obligated to make a
Discretionary Employer Contribution in excess of the maximum amount deductible under Code Section 404(a)(3)(A). 
 (vi)
For purposes of applying the Code Section 401(a)(17) limit described in subsection 2.11(f), the Compensation taken into account shall be the Compensation received for the fiscal year for which the Discretionary Employer Contribution is made,
except that the Compensation shall be determined, and Code Section 401(a)(17) shall be applied, on a fiscal year basis (rather than on a Plan Year basis), and as a result of which, the Code Section 401(a)(17) limit in effect for the Plan
Year in which the fiscal year begins shall apply, as required by Treasury Regulations Section 1.401(a)(17)-1(b)(3)(ii). 

5.2 Special Limitations on Matching Contributions. With respect to each Plan Year, Matching Contributions under the
Plan made on behalf of Highly Compensated Employees for the Plan Year shall not exceed the “contribution percentage requirement” of Code Section 401(m)(2), as provided in this Section. This determination shall be made on a
Participating Employer-by-Participating Employer basis, including any Affiliated Company of each Participating Employer in such Participating Employer’s testing
group. In the event that Matching Contributions under this Plan made on behalf of Highly Compensated Employees for any Plan Year exceed the “contribution percentage requirement” of Code Section 401(m)(2) for any reason, such Excess
Aggregate Contributions and any income allocable thereto shall be disposed of in accordance with Section 5.3, the provisions of Code Sections 401(m)(2) and 401(m)(9) and any applicable regulations. The Actual Contribution Percentage test will
be calculated using the Current Year Testing method described in Treasury Regulation Section 1.401(m)-2(a)(2). 

(a) The Matching Contributions made on behalf of a Participant who is a Highly Compensated Employee for a Plan Year shall
satisfy one of the following tests: 
 (i) The Actual Contribution Percentage for Eligible Employees who are Highly
Compensated Employees shall not be more than the Actual Contribution Percentage of all other Eligible Employees multiplied by 1.25; or 

(ii) The excess of the Actual Contribution Percentage for Eligible Employees who are Highly Compensated Employees over the
Actual Contribution Percentage for all other Eligible Employees shall not be more than two percentage points, and the Actual Contribution Percentage for Eligible Employees who are Highly Compensated Employees shall not be more than the Actual
Contribution Percentage of all other Eligible Employees multiplied by 2.00. 

  
 31 








 (b) For the purposes of this Article 5, “Actual Contribution
Percentage” means, with respect to Eligible Employees who are Highly Compensated Employees and all other Eligible Employees for a Plan Year, the average of the ratios, calculated separately for each Employee in such group, of the amount of
Matching Contributions under the Plan on behalf of each Employee for such Plan Year to such Employee’s Includable Compensation for such Plan Year. 

(c) If as of the last day of a Plan Year this Plan satisfies the requirements of Code Section 401(a)(4) or 410(b) only if
aggregated with one or more other plans which include arrangements under Code Section 401(k), then this Section 5.2 shall be applied by determining the Actual Contribution Percentages of Eligible Employees as if all such plans were a
single plan. 
 (d) For the purposes of this Section, the Actual Contribution Percentage for any Highly Compensated Employee
who is a Participant under two or more Code Section 401(k) arrangements of a Participating Employer or an Affiliated Company shall be determined by taking into account the Highly Compensated Employee’s Compensation (including any
differential wage payment (as defined in Code Section 3401(h)(2)) made by a Participating Employer) under each such arrangement and contributions under each such arrangement which qualify for treatment under Code Section 401(k). 

(e) The determination and treatment of Matching Contributions and the Actual Contribution Percentage of any Participant shall
satisfy such other requirements as may be prescribed by the Secretary of the Treasury. 
 5.3 Return of Excess Aggregate
Contributions on Behalf of Highly Compensated Employees. The Committee shall determine, as soon as is reasonably possible following the close of the Plan Year, the extent (if any) to which Matching Contributions on behalf of Highly
Compensated Employees of each Participating Employer (and its Affiliated Company(ies) (if applicable)) may cause the Plan to exceed the limitations of Section 5.2 for such Plan Year. Notwithstanding any other provision of the Plan, if, pursuant
to the determination by the Committee, Matching Contributions on behalf of a Highly Compensated Employee may cause the Plan to exceed such limitations, then the Committee shall take the following steps: 

(a) First, any Excess Aggregate Contributions on behalf of Highly Compensated Employees, plus any income and minus any loss
allocable thereto, shall be forfeited, to the extent forfeitable under the Plan. Amounts of Excess Aggregate Contributions forfeited by Highly Compensated Employees under this Section shall be applied to the maximum extent practicable, to reduce a
Participating Employer’s Matching Contribution for the Plan Year for which the Excess Aggregate Contribution was made and succeeding Plan Years, as necessary. 

(b) If any excess remains after the provisions of (a) above are applied, any Excess Aggregate Contributions which are non-forfeitable under the Plan, plus any income and minus any loss allocable thereto shall be distributed to the Highly Compensated Employee (after withholding applicable federal, state and local income taxes due on
such amount) within two and one-half (2-1/2) months following the close of the Plan Year for which the Excess Aggregate Contribution was made, but in no event later than
the end of the first Plan Year following the Plan Year for which the excess Matching Contribution was made, notwithstanding any other provision in this Plan. 

  
 32 








 (c) Excess Aggregate Contributions are allocated to the Highly Compensated
Employees with the largest Actual Contribution Percentage amounts taken into account in calculating the Actual Contribution Percentage test for the year in which the excess arose, beginning with the Highly Compensated Employee with the largest
amount of such Actual Contribution Percentage amounts and continuing in descending order until all the Excess Aggregate Contributions have been allocated. For purposes of the preceding sentence, the “largest amount” is determined after
distribution of any Excess Aggregate Contributions. 
 (d) For purposes of this Section, the amount of any Excess Aggregate
Contributions on behalf of a Highly Compensated Employee for a preceding Plan Year under Section 5.2, and any income or loss allocable to any Excess Aggregate Contributions, shall be determined by the Committee in accordance with subsection
4.7(a). The Committee shall not be liable to any Highly Compensated Employee (or his Beneficiary, if applicable) for any losses caused by incorrectly estimating the amount of any Excess Aggregate Contributions on behalf of a Highly Compensated
Employee and the earnings attributable to such excess. In all events, the income attributable to Excess Aggregate Contributions will be determined in accordance with Code Section 401(m) and the regulations issued thereunder. 

(e) Any Excess Aggregate Contribution forfeited by or distributed to a Highly Compensated Employee in accordance with this
Section shall be treated as an Annual Addition under Article 15 for the Plan Year for which the Excess Aggregate Contribution was made. In addition, any forfeited amount reallocated to the Account of another Participant shall be treated as an Annual
Addition with respect to such Participant. 
 5.4 Irrevocability. A Participating Employer 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 a Participating Employer except that on and after the Effective Date funds may be returned to the appropriate Participating Employer
as follows: 
 (a) In the event a Participating Employer shall make an excessive contribution under a mistake of fact
pursuant to ERISA Section 403(c)(2)(A), the Participating Employer may demand repayment of such excessive contribution at any time within one (1) year following the time of payment and the Trustees shall return such amount to the
Participating Employer within the one (1) year period. Earnings of the Plan attributable to the excess contributions may not be returned to the Participating Employer but any losses attributable thereto must reduce the amount so returned. 

(b) Any contribution by a Participating Employer to the Trust Fund is conditioned upon the deductibility of the contribution by
the Participating Employer under the Code and, to the extent any such deduction is disallowed, the Participating Employer may, within one (1) year following the disallowance of the deduction, demand repayment of such disallowed contribution and
the Trustee shall return such contribution within one (1) year following the disallowance. Earnings of the Plan attributable to the excess contribution may not be returned to the Participating Employer, but any losses attributable thereto must
reduce the amount so returned.

Contributions Account, his Discretionary Employer Contributions Account, and his Retirement Account under the Plan as made available by the Committee, subject to the rules set forth in (a)-(d) below. A Participant’s Account may be charged for
the reasonable expenses of carrying out the Participant’s investment directions and for investment adviser fees associated with his or her Account. These provisions are intended to comply with Code Sections 401(a)(28) and 401(a)(35). 

(a) Investment of Accounts in an Investment Fund shall be in such amounts or whole percentages as the Committee shall prescribe

(c) Investment Funds may, from time to time, hold cash or cash equivalent investments (including interests in any fund
maintained by the Trustee as provided in the Trust Agreement) resulting from investment transactions relating to the property of said Fund; provided, however, that neither the Committee, the Company, any Participating Employer, the Trustee nor any
other person shall have any duty or responsibility to cause such Funds to be held in cash or cash equivalent investments for investment purposes. In the case of any Investment Fund under the management and control of an Investment Manager appointed
by the Committee in accordance with Section 11.4, neither the Committee, the Company, any Participating Employer, the Trustee, nor any other person shall have any responsibility or liability for investment decisions made by such Investment
Manager.

Section 4.1 in effect with the Participating Employer on December 31 of the applicable Plan Year. 
 7.5 DXC Stock
Fund. In connection with the Separation, the Plan will maintain the DXC Stock Fund that is a portion of the assets transferred from the DXC MAP. After the Separation, in order to permit Participants a reasonable opportunity to decide
when they wish to liquidate, in an orderly fashion, their investment in the DXC Stock Fund, the Plan will maintain the DXC Stock Fund in accordance with the following special rules: 

(a) No new investment in the DXC Stock Fund shall be permitted. Any cash dividends paid with respect to a Participant’s
interest in the DXC Stock Fund shall be reinvested in the DXC Stock Fund, subject to Article XX and Section 20.4. 
 (b)
The DXC Stock Fund shall be maintained until such date as determined by the Committee for the purpose of permitting Participants the opportunity to divest their interests in the DXC Stock Fund. Prior to the date selected by the Committee,
Participants may direct the transfer of investments out of the DXC Stock Fund, subject to Article 7, but may not direct any transfers, contributions or other investments into the DXC Stock Fund. Commencing on the date selected by the Committee,
there shall be implemented measures as determined by the Committee to liquidate, in an orderly fashion, the common stock of DXC held in the DXC Stock Fund. At the conclusion of such liquidation, the proceeds from the liquidation shall be deposited
in Participant Accounts in an Investment Fund to be determined by the Committee. 
 (c) Each Participant shall be entitled to
direct the manner in which the shares (including fractional shares) of DXC common stock in his or her Account in the DXC Stock Fund are to be voted. The Trustee shall vote such shares in accordance with the directions of the Participants. This
requirement will be met if the Trustee votes the combined fractional shares to the extent possible to reflect the direction of the voting Participants. All shares credited to Participants’ Accounts as to which the Trustee does not receive
voting directions, and all unallocated shares held by the Trustee, shall be voted by the Trustee proportionately in the same manner as the Trustee votes shares as to which the Trustee has received voting instructions. The Company will cause proxy
materials to be distributed to all Participants who have an Account balance in the DXC Stock Fund prior to each stockholders’ meeting at the same time it distributes such materials to all other stockholders.

 ARTICLE IX 

PAYMENT OF PLAN BENEFITS 

9.1 Distribution Upon Retirement. 

(a) A Participant may retire from the employment of a Participating Employer on his Early Retirement Date or his Normal
Retirement Date. If the Participant continues in the service of a Participating Employer beyond his Normal Retirement Date, he shall continue to participate in the Plan in the same manner as Participants who have not reached their Normal Retirement
Dates. At the Participant’s Severance on his Postponed Retirement Date, his Distributable Benefit shall be based upon the Vested Interest of his Accounts as of the applicable Valuation Date. After a Participant has reached his Normal Retirement
Date, any Severance (other than by reason of death or Total and Permanent Disability) shall be deemed a Normal Retirement. 

(b) Subject to the provisions of Sections 9.4 and 9.11, upon a Participant’s Severance on or after his Early Retirement
Date or Normal Retirement Date such Participant shall be entitled to a distribution of his Distributable Benefit as provided in Section 9.6 within ninety (90) days after receipt by the Committee of all required documentation, but in no
event shall payment be made later than the sixtieth day after the later of the close of the Plan Year in which occurs the Severance, or the close of the Plan Year in which the Participant attains Normal Retirement Age, unless such Participant
consents to a later distribution. 
 (c) All distributions under this Plan must be made in accordance with the regulations
under Code Section 401(a)(9), including the incidental death benefit of Code Section 401(a)(9)(G). Furthermore, the provisions of this Article 9 reflecting Code Section 401(a)(9) override any other distribution options in the Plan
inconsistent with Code Section 401(a)(9). 
 (d) The following provisions shall apply with respect to distributions:

 (i) In accordance with procedures described in this subsection 9.1(d), a Participant who (i) is not a five percent
owner (as defined in Code Section 416), (ii) attains age 70  1⁄2 while actively employed by the Company, and (iii) has not otherwise commenced
payment of his Distributable Benefit as of the date an election is made shall be given a one-time option to elect to commence an in-service distribution of a portion of
his or her Distributable Benefit beginning on or before April 1 of the calendar year following the calendar year in which the Participant attains age 70
 1⁄2 (“Voluntary Minimum Distribution” or “VMD”). The procedures for electing, calculating the amount of, and paying a VMD are as follows:

 (1) The option to elect shall be given in the January of the year in which the Participant reaches age 70  1⁄2. The Participant shall have the period specified in the notice, which shall not be less than 30 days from the date of the notice, to elect a VMD (the “VMD
Election Period”). 

  
 41 








 (2) If the Committee receives a properly completed and signed election form
within the VMD Election Period, the VMD shall be paid in an amount equal to the amount, and shall be distributed in the same time and manner, that the Participant would have received as the Participant’s required minimum distribution calculated
under subsection 9.1(c) of the Plan; provided, however, that the required minimum distribution shall be calculated based on the Participant’s Account balance on the VMD Date. The VMD Date shall be the last business day of November of the year
in which the Participant reaches age 70  1⁄2. 

(ii) Any Participant who is not a five percent owner (as defined in Code Section 416) and who is hired by the Company
after the Participant attains age 70  1⁄2 shall be given the one-time option to elect to commence a VMD pursuant to the
terms set forth in subsection 9.1(d)(i) above in the January of the first Plan Year commencing after the first December 31 on which the Participant has an Account balance. 

(iii) Any Participant who is not a five percent owner (as defined in Code Section 416) and who is rehired after attaining
age 70  1⁄2 shall be given the one-time option to elect to commence a VMD pursuant to the terms set forth in subsection
9.1(d)(i) above; provided, however, that a rehired Participant may elect a VMD only if the Participant was not otherwise given the one-time option to take a VMD prior to his date of rehire. 

(iv) Notwithstanding any provision of the Plan to the contrary, a Participant who is receiving a VMD at the time of his
Severance Date shall cease receiving such VMD and instead commence receiving his Distributable Benefit in the form elected by the Participant in accordance with Article 9 of the Plan. Notwithstanding anything herein to the contrary, if a Participant
has elected to receive a VMD which has not yet commenced at the time of his retirement under the Plan, such election shall be cancelled and the Participant shall instead commence receiving his Distributable Benefit in the form elected by the
Participant at retirement in accordance with Article 9 of the Plan. 
 (v) Notwithstanding anything herein to the contrary, a
Participant shall not receive a VMD concurrently with the Participant’s required minimum distributions paid in accordance with subsection 9.1(c). With respect to a Participant who was actively employed by the Company and receiving required
minimum distributions as of October 1, 1998, that Participant shall have a one-time election to cease and defer distribution of his required minimum distribution until April 1 of the later of
(i) the year in which the Participant reaches age 70  1⁄2; or (ii) the year following the Participant’s Severance Date. 

(e) Notwithstanding anything in subsection 9.1(d) to the contrary, the required minimum distribution of the Distributable
Benefit of a Participant who is a five percent owner (as defined in Code Section 416) must begin by April 1 of the calendar year following the calendar year in which the Participant attains age 70
 1⁄2. 

  
 42 








 (f) Notwithstanding the foregoing provisions of Section 9.1, a Participant
or Beneficiary who would have been required to receive required minimum distributions for 2009 but for the enactment of Code Section 401(a)(9)(H) (“2009 RMDs”), and who would have satisfied that requirement by receiving distributions
that are (1) equal to the 2009 RMDs or (2) one or more payments in a series of substantially equal distributions (that include the 2009 RMDs) made at least annually and expected to last for the life (or life expectancy) of the Participant,
the joint lives (or joint life expectancy) of the Participant and the Participant’s designated Beneficiary, or for a period of at least 10 years (“Extended 2009 RMDs”), will receive those distributions for 2009, unless the Participant
or Beneficiary chooses not to receive such distributions. Participants and Beneficiaries described in the preceding sentence will be given the opportunity to elect to stop receiving the distributions described in the preceding sentence.
Notwithstanding the foregoing provisions of this subsection 9.1(f), for purposes of applying the direct rollover provisions of the Plan, 2009 RMDs and Extended 2009 RMDs (both as defined above) are not treated as eligible rollover distributions.

 9.2 Distribution Upon Death Prior to Payment of Benefits. 

(a) Upon the death of a Participant prior to the payment of his Distributable Benefit, the Committee shall direct the Trustee
to make a distribution of such Distributable Benefit as provided in Section 9.6 to the Beneficiary designated by the deceased Participant, or otherwise entitled to such Distributable Benefit, as provided in Section 9.8. 

(b) Distribution of a Participant’s Distributable Benefit shall be made within ninety (90) days after all facts
required by the Committee to be established as a condition of payment have been established to the satisfaction of the Committee, but in any event within the maximum time period allowed by Code Section 401(a)(9). 

(c) If a Participant dies while performing qualified military service (as defined in Code Section 414(u)(5)), the
Participant’s Beneficiary shall be entitled to any additional benefits under the Plan as if the Participant had died during service with a Participating Employer. 

9.3 Distribution Upon Disability Prior to Retirement Date. 

(a) Upon the Severance of a Participant as a result of Total and Permanent Disability, which shall be certified by a physician
designated by the Committee, if the Committee so requests, his Distributable Benefit shall be distributed to him as provided in Section 9.6. 

(b) Distribution to a disabled Participant shall be made within ninety (90) days after all facts required by the Committee
to be established as a condition of payment have been established to the satisfaction of the Committee. 

  
 43 








 9.4 Severance Prior to Normal Retirement Date. 

(a) If a Participant incurs a Severance prior to his Normal Retirement Date for any reason other than Total and Permanent
Disability or death, his Distributable Benefit shall be paid in a lump sum as provided in Section 9.6 as soon as practicable following the Participant’s attainment of Normal Retirement Age; provided, however, that in no event shall such
distribution be later than sixty (60) days after the close of the Plan Year in which the Participant attains Normal Retirement Age, unless such Participant elects to defer receipt of such payment until such Participant attains age 70  1⁄2. 
 (b) Payment of a
Participant’s Distributable Benefit under this Section 9.4 shall be made in a lump sum as provided in Section 9.6 before the Participant’s attainment of Normal Retirement Age within ninety (90) days after receipt by the
Committee of all required documentation (but in no event later than sixty (60) days after the close of the Plan Year in which the Participant attains Normal Retirement Age) as follows: 

(i) In the case of a Participant whose Distributable Benefit exceeds $5,000 (not including the amount of any Rollover Account
or Roth Rollover Account) if the Participant elects in writing to receive payment of such Distributable Benefit. 
 (ii) In
the case of a Participant whose Distributable Benefit does not exceed $1,000 (including the amount of any Rollover Account or Roth Rollover Account) without such Participant’s election. 

(iii) In the case of a Participant whose Distributable Benefit does not exceed $5,000 (not including the amount of any Rollover
Account or Roth Rollover Account) and is more than $1,000 (including the amount of any Rollover Account), then the Committee shall pay the Distributable Benefit as a direct rollover to an individual retirement plan designated by the Committee
without such participant’s election. Notwithstanding the preceding sentence, if the Participant elects in writing to receive payment of such Distributable Benefit, it shall be paid to the Participant. 

9.5 Forfeitures; Restoration. 

(a) Subject to the provisions of subsection 9.5(c) below, any non-vested portion of a
Participant’s Matching Contributions Account shall be forfeited as of the earlier of the date the Participant’s Distributable Benefit is paid to him as provided in Section 9.4 or the date the Participant incurs five
(5) consecutive Breaks in Service. 
 (b) Any non-vested portion of a
Participant’s Matching Contributions Account which is forfeited in accordance with (a) above shall be applied to reduce Matching Contributions by a Participating Employer under subsection 5.1(a)(iii) or to restore amounts previously
forfeited, as provided in subsection 9.5(c) below, or shall be applied to reduce Employer Discretionary Contributions, or shall be used for corrective allocations as permitted under the IRS Employee Plans Compliance Resolution System (EPCRS), or
shall be used to pay for Plan administrative expenses, and shall not otherwise be repaid or recovered by a Participating Employer. 

  
 44 








 (c) In accordance with such rules as the Committee may prescribe, there shall be
restored to the Participant’s credit in his Matching Contributions Account a number of shares of Stock equal in value to the dollar value of any non-vested portion of a Participant’s Matching
Contributions Account which was forfeited upon payment of the Participant’s Distributable Benefit in accordance with subsection 9.4(b) prior to the date on which he incurs five (5) consecutive Breaks in Service; provided, however, that
such restoration shall be made only in the case of the Participant’s reemployment as an Employee prior to incurring five (5) consecutive Breaks in Service, and upon the Participant’s repayment of the amount distributed under
Section 9.4 within five (5) years of the Participant’s reemployment. The determination of the dollar value of the forfeited portion of the Participant’s Matching Contributions Account required to be restored to the Participant
shall be made as of the Valuation Date the Participant’s Accounts were valued for purposes of determining his Distributable Benefit, as provided in Article 10. No adjustment in the dollar value of the forfeited amounts shall be made for any
gains or losses of any Investment Fund, including the Perspecta Stock Fund, between the applicable Valuation Date and the restoration of the dollar value of the forfeited portion of the Participant’s Matching Contributions Account. 

9.6 Payment of Distributable Benefit. 

(a) Form of Distribution. If a Participant has a Merged Account that has received amounts directly from another
qualified plan that provides for an annuity form of distribution, such Merged Account shall be distributed in accordance with Section 9.12. Otherwise, a Participant may elect to receive the entire Vested Interest balance of his Accounts in one
of the following forms: 
 (i) Single lump sum payment. 

(ii) Period certain in five, ten or other yearly period as elected by the Participant, but not beyond the life expectancy of
the Participant. 
 (iii) A fixed monthly, quarterly or annual amount, as elected by the Participant, the duration of which
ends on the earlier of the date such Participant’s Account balance equals $0 (zero dollars) or age 70 1⁄2, at which time payment shall be in a variable
amount not to exceed such Participant’s life expectancy. 
 (iv) If a Participant elects a payment method described in
subsections 9.6(a)(ii) or (iii) above, such installment payments shall be made from such Participant’s Accounts on a pro rata basis by Investment Fund in the Participant’s Accounts. The amounts remaining in a Participant’s
Account shall be subject to Section 7.3. 
 (v) A Participant who makes an election pursuant to subsections 9.6(a)(ii)
or (iii) subsequently may elect to receive any remaining balance in a lump sum as provided in subsection 9.6(a)(i). 

  
 45 








 (b) Manner of Payment. All distributions shall be valued as of the
Valuation Date on which such amounts are distributed. Payment of a Participant’s Distributable Benefit reflecting the Participant’s interest in the Perspecta Stock Fund (and/or DXC Stock Fund) shall be made in shares of Stock (together
with cash in lieu of any fractional share), unless the Participant elects to receive his entire distribution in cash; provided, however, that all distributions pursuant to subsections 9.4(b)(ii) or (iii) shall be made in cash, unless the
Participant elects to receive a distribution pursuant to subsection 9.4(b)(ii) or (iii) in shares of Stock (together with cash in lieu of any fractional share). Unless a Participant specifically requests that his Distributable Benefit
attributable to Investment Funds other than the Perspecta Stock Fund (and/or DXC Stock Fund) be made in Stock, such portion of his Distributable Benefit shall be made in cash; provided, however, that a Distributable Benefit pursuant to subsection
9.4(b)(iii) shall be made only in cash. The payment of a Participant’s Distributable Benefit in Stock (other than the portion of the distribution representing the Participant’s interest in the Perspecta Stock Fund and/or DXC Stock Fund)
shall consist of a number of shares of Stock equal to the number of shares of Stock which can be purchased with the dollar value of the Participant’s Distributable Benefit (other than the portion of the distribution representing the
Participant’s interest in the Perspecta Stock Fund and/or DXC Stock Fund), such value to be determined as of the appropriate Valuation Date determined under Article 10. 

9.7 Withdrawals. 

(a) Hardship Distributions. 

(i) Upon at least thirty (30) days written notice to the Committee, a Participant who is an Employee may obtain a hardship
distribution if the Committee finds that the distribution is necessary to relieve a “financial hardship” incurred by the Participant. A Participant will be considered to have incurred a financial hardship only if he has immediate and heavy
financial needs that cannot be fulfilled through other reasonably available resources of the Participant. “Immediate and heavy financial needs” means: 

(1) Expenses for medical care described in Code Section 213(d) previously incurred by the Participant, the
Participant’s Spouse, or any dependents of the Participant (as defined in Code Section 152) or any Beneficiary under the Plan with respect to the Participant or necessary for these persons to obtain such medical care; 

(2) The purchase (excluding mortgage payments) of a principal residence for the Participant; 

(3) Payment of tuition and related educational fees for the next 12 months of post-secondary education for the Participant or
his Spouse, children or dependents (as defined in Code Section 152) or Beneficiary; 
 (4) The need to prevent the
eviction of the Participant from his principal residence or foreclosure on the mortgage of that residence; 

  
 46 








 (5) Payments for burial or funeral expenses for the Participant’s deceased
parent, Spouse, children, dependents (as defined in Code Section 152), or Beneficiary; 
 (6) Expenses for the repair
of damage to the Participant’s principal residence that would qualify for the casualty deduction under Code Section 165; and 

(7) Such additional expenses or payments approved by the Internal Revenue Service. 

(ii) The determination of hardship shall be made by the Committee in a uniform and nondiscriminatory manner in accordance with
such standards as may be promulgated from time to time by the Internal Revenue Service. The Committee may rely on the Participant’s representation that the financial need cannot be relieved: 

(1) Through reimbursement or compensation by insurance or otherwise; 

(2) By reasonable liquidation of the Participant’s assets, to the extent such liquidation would not itself cause an
immediate and heavy financial need; 
 (3) By cessation of Compensation Deferral Contributions under the Plan; or 

(4) By other distributions or non-taxable loans from plans maintained by the Company
or by any other employer, or by borrowing from commercial sources on reasonable commercial terms. 
 (iii) A distribution
will be deemed necessary to satisfy an immediate and heavy financial need of the Participant if all of the following requirements are met: 

(1) The distribution is not in excess of the amount of the immediate and heavy financial need of the Participant; 

(2) The Participant has obtained all distributions, other than hardship withdrawals, and all
non-taxable loans currently available under this Plan and all plans maintained by the Company or an Affiliated Company; and 

(3) The Participant’s Compensation Deferral Contributions, and elective contributions and employee contributions under
this Plan and all other plans maintained by the Company or an Affiliated Company will be suspended for six months after receipt of the withdrawal. 

  
 47 








 (iv) A distribution may include any amount necessary to pay any federal, state,
or local income taxes or penalties reasonably anticipated to result from the distribution. 
 (b) While still an Employee, a
Participant may, upon at least thirty (30) days written notice to the Committee, make a withdrawal from his Retirement Account of an amount specified by him up to the whole amount thereof. A Participant who makes a withdrawal under this
subsection 9.7(b) shall not be eligible to again make a withdrawal under this subsection 9.7(b) prior to the first anniversary of the date the Participant’s most recent withdrawal under this subsection 9.7(b) was distributed to him. 

(c) While still an Employee, a Participant who has attained at least age fifty-nine and
one-half (59 1⁄2) and has a one hundred percent (100%) Vested Interest in the value of his Accounts under the Plan
may, upon at least thirty (30) days written notice to the Committee, make a withdrawal from his Accounts of the amount specified by him, up to the total value of his Vested Interest in his Accounts. A Participant who makes a withdrawal under
this subsection 9.7(c) shall not be eligible to again make a withdrawal under this subsection 9.7(c) prior to the first anniversary of the date the Participant’s most recent withdrawal under this subsection 9.7(c) was distributed to him. A
Participant shall have a separate withdrawal option under this subsection 9.7(c) for his Roth Accounts, if applicable. 
 (d)
While still an Employee, a Participant may, upon at least thirty (30) days written notice to the Committee, make a withdrawal from his Merged Account of all amounts thereof attributable to transfers from other profit sharing plans and amounts
attributable to other pension plans and Code Section 401(k) plans provided the Participant had the right to elect to receive a distribution of such amount at the time of the transfer to this Plan. No withdrawals under this provision shall be
permitted of any amounts transferred from an account that qualifies under Code Section 401(k) if the Participant did not have the right to receive a distribution at the time of the transfer. A Participant who makes a withdrawal under this
subsection 9.7(d) shall not be eligible to again make a withdrawal under this subsection 9.7(d) prior to the first anniversary of the date the Participant’s most recent withdrawal under this subsection 9.7(d) was distributed him. 

(e) Rollover Account and Roth Rollover Account amounts may be withdrawn at any time for any reason. 

(f) The maximum amount subject to withdrawal under this Section 9.7 shall be determined as of the Valuation Date
immediately following the Committee’s determination authorizing the withdrawal. 
 (g) Any withdrawal under this
Section 9.7 reflecting the Participant’s interest in the Perspecta Stock Fund shall be made in shares of Stock (together with cash in lieu of any fractional share), unless the Participant elects to receive such entire amount in cash. Any
withdrawal from an Investment Fund other than the Perspecta Stock Fund shall be in Stock or cash, as determined in accordance with the provisions of subsection 9.6(b). Such withdrawals shall be distributed as soon as practicable following the
Committee’s determination authorizing a withdrawal. Similar provisions shall apply with respect to DXC Stock in the DXC Stock Fund. 

  
 48 








 9.8 Designation of Beneficiary. 

(a) Subject to the provisions of subsection 9.8(b) below, each Participant shall have the right to designate a Beneficiary or
Beneficiaries to receive his Vested Interest in the Trust Fund in the event of his death before receipt of his entire Vested Interest in the Trust Fund. This designation is to be made on the form prescribed by and delivered to the Committee. Subject
to the provisions of subsection 9.8(b) below, a Participant shall have the right to change or revoke any such designation by filing a new designation or notice of revocation with the Committee, and no notice to any Beneficiary nor consent by any
Beneficiary shall be required to effect any such change or revocation. 
 (b) If a Participant designates a non-Spouse as the Beneficiary of his Vested Interest in the Trust Fund and on the date of his death has a Spouse, no effect shall be given to such designation unless such Spouse has consented in writing to such
designation and such consent is witnessed by a notary public. If a Participant designates a non-Spouse Beneficiary and the surviving Spouse does not consent to such designation, the surviving Spouse shall be
deemed the Beneficiary of the deceased Participant. A Spouse’s consent to a Beneficiary designation is not required under the following circumstances: 

(i) if it is established to the satisfaction of the Committee that there is no Spouse; or 

(ii) if the Participant’s Spouse cannot be located; or 

(iii) because of other circumstances under which a Spouse’s consent is not required in accordance with applicable Treasury
or Department of Labor Regulations. 
 (c) If a deceased Participant has failed to designate a Beneficiary, or if the
Committee, after reasonable efforts have been made, is unable to locate a form designating a Beneficiary, but has a Surviving Spouse, such Surviving Spouse shall be the Beneficiary and the Participant’s
non-forfeitable accrued benefit (reduced by any security interest held by the Plan by reason of a loan outstanding to such Participant) shall be payable in full to such deceased Participant’s Surviving
Spouse. In the case of a deceased Participant who has no Surviving Spouse, and such deceased Participant shall have (i) failed to designate a Beneficiary, or (ii) if the Committee shall be unable to locate a designated Beneficiary after
reasonable efforts have been made, or (iii) if for any reason the designation shall be legally ineffective, or (iv) if the Committee after reasonable efforts have been made, is unable to locate a form designating a Beneficiary, or
(v) if the Beneficiary shall have predeceased the Participant and the Participant did not designate a successor Beneficiary, then the Participant’s estate shall be the Beneficiary and the Participant’s
non-forfeitable accrued benefit (reduced by any security interest held by the Plan by reason of a loan outstanding to such Participant) shall be payable in full to such estate within one (1) year after
the Participant’s death. 

  
 49 








 (d) In the event that the deceased Participant was not a resident of California
at the date of his death, the Committee, in its discretion, may require the establishment of ancillary administration in California. In the event that a Participant shall predecease his Beneficiary and on the subsequent death of the Beneficiary a
remaining distribution is payable under the applicable provisions of this Plan, the distribution shall be payable to the estate of the Beneficiary, subject to the same provisions concerning non-California
residency and the establishment of ancillary administration as are applicable on the death of the Participant. 
 (e) The
Committee shall not be required to authorize any payment to be made to any person following a Participant’s death, whether or not such person has been designated by the Participant as Beneficiary, if the Committee determines that the Plan may
be subject to conflicting claims in respect of said payment for any reason, including, without limitation, the designation or continuation of a designation of a Beneficiary other than the Participant’s Spouse without the consent of such Spouse
to the extent such consent is required by Code Section 401(a). In the event the Committee determines in accordance with this subsection 9.8(e) not to make payment to a designated Beneficiary, the Committee shall take such steps as it determines
appropriate to resolve such potential conflict. The provisions of this Section 9.8 shall not be construed to place upon the Company or the Committee any duty or obligation to require the consent of a Spouse for the purpose of protecting the
rights or interests of present or former Spouses of Participants, except to the extent required to comply with Code Section 401(a)(11) or ERISA Section 205. 

9.9 Facility of Payment. If any payee under the Plan is a minor or if the Committee reasonably believes that any
payee is legally incapable of giving a valid receipt and discharge for any payment due him, the Committee may have the payment or any part thereof, made to the person (or persons or institution) whom it reasonably believes is caring for or
supporting the payee, unless it has received due notice of claim therefor from a duly appointed guardian or custodian 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. 
 9.10 Payee Consent. To the extent required to comply
with Code Section 411(a)(11), the Committee shall require each Participant or other payee to consent to any payment of a Participant’s Accounts. 

9.11 Additional Requirements for Distribution. 

(a) The Committee or Trustee, or both, may require the execution and delivery of such documents, papers and receipts as the
Committee or Trustee may determine necessary or appropriate in order to establish the fact of death of the deceased Participant and of the right and identity of any Beneficiary or other person or persons claiming any benefits under this Article 9.


  
 50 








 (b) The Committee 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 Committee or Trustee, or both, may deem appropriate as protection against possible liability for state or federal death taxes attributable to any
death benefits. 
 (c) Notwithstanding any other provision in this Article 9 regarding the time within which a
Participant’s Distributable Benefit will be paid, if, in the opinion of the Committee there are or reasonably may be conflicting claims or other legal impediments to the payment of such Distributable Benefit to a payee, such payment may be
delayed for so long as is necessary to resolve such conflict, potential conflict, or other legal impediment, but not beyond the date permitted by applicable law. 

(d) The Committee shall notify each recipient of an “eligible rollover distribution” (as defined in
Section 9.13(d)(i)) of his distribution options within a reasonable period of time prior to making such distribution. 
 9.12
Distribution from Merged Accounts. The provisions of this Section 9.12 shall apply to any Participant whose Accounts include a Merged Account that has received amounts directly from another qualified plan that provides
for an annuity form of distribution. 
 (a) Qualified Joint and Survivor Annuity. Unless an optional form of benefit is selected
pursuant to a qualified election within the 90-day period ending on the annuity starting date, a married Participant’s Merged Account will be paid in the form of a Qualified Joint and Survivor Annuity and
an unmarried Participant’s Merged Account will be paid in the form of a life annuity. The Participant may elect to have such annuity distributed upon attainment of the earliest retirement age under the Plan. 

(b) Qualified Pre-retirement Survivor Annuity. Unless an optional form of benefit has been
selected within the election period pursuant to a qualified election, if a Participant dies before the annuity starting date then the entire balance of the Participant’s Merged Account shall be applied toward the purchase of an annuity for the
life of the Surviving Spouse. Such an annuity shall provide for annual payments to the Surviving Spouse and shall have a value that is equal to 100 percent (100%) of the Participant’s non-forfeitable
account balance, including the proceeds of any insurance on the Participant’s life, as of the date of the Participant’s death. Such Surviving Spouse may direct the Committee as to the commencement of payments under the Qualified Pre-retirement Survivor Annuity within a reasonable time after the death of the Participant. In addition, the Surviving Spouse may elect to waive the right to a survivor annuity and in lieu thereof, receive a lump
sum distribution of the entire balance of the Participant’s Merged Account. 
 (c) Optional Form of Benefit. During the election
period, a Participant may, pursuant to a qualified election, select as an optional form of benefit in lieu of an annuity form of distribution either one of the following forms of distribution: (a) a series of substantially equal annual or more
frequent installments over a period certain not extending beyond the earlier of (i) the end of the period measured by the joint life and last survivor expectancy of the Participant and his Spouse, or (ii) twenty years; or (b) a lump
sum distribution in accordance with subsection 9.6(a). In addition, a Participant shall be entitled to elect any additional optional form of benefit provided by a transferor plan and which is a protected benefit under Code Section 411(d)(6).


  
 51 








 (d) For purposes of this Section 9.12 the following definitions shall apply: 

(i) Election Period. The period which begins on the first day of the Plan Year in which the Participant attains age 35
and ends on the date of the Participant’s death. If a Participant separates from Service prior to the first day of the Plan Year in which age 35 is attained, the election period shall begin on the Participant’s Severance Date. A
Participant who will not yet attain age 35 as of the end of any current Plan Year may make a special qualified election to waive the qualified pre-retirement survivor annuity for the period beginning on the
day of such election and ending on the first day of the Plan Year in which the Participant will attain age 35. Such election shall not be valid unless the Participant receives a written explanation of the qualified
pre-retirement survivor annuity in such terms as are comparable to the pre-retirement survivor annuity explanation required under subsection 9.12(b). Qualified pre-retirement survivor annuity coverage will be automatically reinstated as of the first day of the Plan Year in which the Participant attains age 35. Any new waiver on or after such date shall be subject to the
full requirements of this Section 9.12. 
 (ii) Earliest Retirement Age. The earliest date on which, under the
Plan, the Participant could elect to receive retirement benefits. 
 (iii) Qualified Election. A waiver of a Qualified
Joint and Survivor Annuity or a qualified pre-retirement survivor annuity shall not be effective unless (i) the Participant’s Spouse consents in writing to the election; (ii) the election
designates a specific Beneficiary, including any class of Beneficiaries or any contingent Beneficiaries, which may not be changed without spousal consent (or the Spouse expressly permits designations by the Participant without any further spousal
consent); (iii) the Spouse’s consent acknowledges the effect of the election; and (iv) the Spouse’s consent is witnessed by a Plan representative or notary public. Additionally, a Participant’s waiver of the Qualified Joint and
Survivor Annuity shall not be effective unless the election designates a form of benefit payment which may not be changed without spousal consent (or the Spouse expressly permits designations 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 will be deemed a qualified election. 

Any consent obtained under this provision (or establishment that the consent of a Spouse may not be obtained) shall be
effective only with respect to such Spouse. A consent that permits designations by the Participant without any requirement of further consent by such Spouse must 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 either or both of 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. No consent obtained under this provision shall be valid unless the Participant has received notice as provided in subsection 9.12(e) below. 

  
 52 








 (iv) Qualified Joint and Survivor Annuity. 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% and not more than 100% of the amount of the annuity which is payable during the joint lives of the Participant and the Spouse and which is the
amount of benefit which can be purchased with the Participant’s Merged Account. The percentage of the survivor annuity shall be either 50% or 100%, as selected by the Participant. 

(v) Annuity Starting Date. The first day of the first period for which an amount is payable as an annuity or any other
form. 
 (e) Notice Requirements. 

(i) In the case of a Qualified Joint and Survivor Annuity, the Committee shall no less than 30 days and no more than 90 days
prior to the Annuity Starting Date provide each Participant a written explanation of: (i) the terms and conditions of a Qualified Joint and Survivor Annuity; (ii) the Participant’s right to make and the effect of an election to waive
the Qualified Joint and Survivor Annuity form of benefit; (iii) the rights of a Participant’s Spouse; and (iv) the right to make, and the effect of, a revocation of a previous election to waive the Qualified Joint and Survivor
Annuity. 
 (ii) In the case of a qualified pre-retirement survivor annuity as
described in subsection 9.12(b), the Committee shall provide each Participant within the applicable period for such Participant a written explanation of the qualified pre-retirement survivor annuity in such
terms and in such manner as would be comparable to the explanation provided for meeting the requirements of subsection 9.12(e)(i) applicable to a Qualified Joint and Survivor Annuity. The applicable period for a Participant is whichever of the
following periods ends last: (i) the period beginning with the first day of the Plan Year in which the Participant attains age 32 and ending with the close of the Plan Year preceding the Plan Year in which the Participant attains age 35; (ii) a
reasonable period ending after the individual becomes a Participant; or (iii) a reasonable period ending after this Section 9.12 first applies to the Participant. 

Notwithstanding the foregoing, notice must be provided within a reasonable period ending after separation from Service in the
case of a Participant who incurs a Severance before attaining age 35. 

  
 53 








 For purposes of the preceding paragraph, a reasonable period ending after the
enumerated events described in (ii) and (iii) is the end of the two year period beginning one year prior to the date the applicable event occurs, and ending one year after that date. In the case of a Participant who separates from Service
before the Plan Year in which age 35 is attained, notice shall be provided within the two year period beginning one year prior to the Participant’s Severance Date and ending one year after such Severance Date. If such a Participant thereafter
returns to employment with a Participating Employer, the applicable period for such Participant shall be redetermined. 
 9.13 Direct
Transfer of Distribution. 
 (a) Notwithstanding any provision of the Plan to the contrary that would otherwise limit
a Distributee’s election under this Section, a Distributee may elect, at the time and in the manner prescribed by the Committee, to have any portion of an eligible rollover distribution paid directly to an eligible retirement plan specified by
the Distributee in a direct rollover. 
 (b) Solely to the extent permitted in Code Sections 408A(c)(3)(B), 408A(d)(3), and
408A(e) and the regulations and other guidance issued thereunder, an eligible Participant may elect to roll over any portion of a distribution of his Account to a Roth IRA (as defined by Code Section 408A) in a “qualified rollover
contribution” (as defined in Code Section 408A(e)), provided that the rollover requirements of Code Section 402(c) are met. The amount of the qualified rollover contribution that would be includible in the Participant’s gross
income were it not part of a qualified rollover contribution shall be included in the Participant’s gross income in accordance with Code Section 408A(d)(3). In addition, the 10% penalty tax on early distributions from qualified retirement
plans imposed by Code Section 72(t) shall not apply to qualified rollover contributions. 
 (c) Notwithstanding the
provisions of this Section 9.13, solely to the extent permitted under Code Section 402(c)(11) and the regulations and other guidance issued thereunder, with respect to any portion of a distribution from the Plan on behalf of a deceased
Participant, if a direct trustee-to-trustee transfer is made to an individual retirement plan described in Code Section 402(c)(8)(B)(i) or (ii), which individual
retirement plan is established for the purposes of receiving the distribution on behalf of an individual who is a designated beneficiary (as defined by Code Section 401(a)(9)(E)) of the Participant and who is not the Surviving Spouse of the
Participant, the transfer shall be treated as an eligible rollover distribution for purposes of this Plan and Code Section 402(c). For purposes of this paragraph, to the extent provided in regulations or other guidance prescribed by the
Internal Revenue Service under Code Section 402(c)(11), a trust maintained for the benefit of one or more designated beneficiaries shall be treated in the same manner as a trust designated beneficiary. 

  
 54 








 (d) For purposes of this Section 9.13, the following definitions shall
apply: 
 (i) Eligible Rollover Distribution. An eligible rollover distribution is any distribution of all or any
portion of a Participant’s vested Account, except that an eligible rollover distribution does not include: any distribution that is one of a series of substantially equal periodic payments, made not less frequently than annually, for the life,
or life expectancy, of the Participant or the Participant’s designated Beneficiary or the joint lives (or joint life expectancies) of the Participant and the Participant’s designated Beneficiary, or for a specified period of 10 years or
more; any distributions, to the extent such distribution is required under Code Section 401(a)(9); and any amount distributed on account of hardship. Notwithstanding any provision of the Plan to the contrary, a portion of a distribution shall
not fail to be an eligible rollover distribution merely because the portion consists of voluntary employee contributions that are not includible in gross income; provided, however, such portion may be transferred only to an individual retirement
account or annuity described in Code Section 408(a) or (b), a qualified retirement plan (either a defined contribution plan or a defined benefit plan) described in Code Section 401(a) or 403(a), or an annuity contract described in Code
Section 403(b) that agrees to separately account for amounts so transferred. 
 (ii) Eligible Retirement Plan. An
eligible retirement plan is an individual retirement account described in Code Section 408(a), an individual retirement annuity described in Code Section 408(b), an annuity plan described in Code Section 403(a), a qualified trust
described in Code Section 401(a), an eligible deferred compensation plan described in Code Section 457(a), an eligible deferred compensation plan described in Code Section 457(b) that is maintained by an eligible employer described in
Code Section 457(e)(1)(A) and that agrees to separately account for amounts rolled into such plan from this Plan, an annuity contract described in Code Section 403(b), or a Roth IRA if the rollover requirements of Code Sections 402(c) and
408A (as applicable) are met, that accepts the Participant’s or Beneficiary’s eligible rollover distribution. 

(iii) Distributee. A Distributee is an Employee or former Employee. In addition, the Employee’s Surviving Spouse
and the Employee’s former Spouse who is the alternate payee pursuant to a qualified domestic relations order, as defined in Code Section 414(p), are Distributees with regard to the interest of the Spouse or former Spouse. Notwithstanding
the foregoing, in accordance with subsection 9.13(c), a designated beneficiary of the Participant who is not the Surviving Spouse of the Participant is also a Distributee. 

(iv) Direct Rollover. A direct rollover is a payment by the Plan to the Eligible Retirement Plan specified by the
Distributee. 

  
 55 








 (e) Notwithstanding the foregoing, with respect to distributions from a
Participant’s Roth Accounts, a portion of a distribution shall not fail to be considered an eligible rollover distribution merely because such portion is not includable in the disributee’s gross income (determined without regard to the
rollover). However, notwithstanding the preceding sentence, such portion may be transferred only to a Roth IRA or transferred in a direct trustee to trustee transfer to a designated Roth account under a qualified defined contribution plan described
in Code Section 401(a) that agrees (in a form satisfactory to the Committee) to separately account for the portion of such distribution which is not so includible. Within a reasonable time after the occurrence of a direct rollover of a
distribution from a Participant’s Roth Accounts under the Plan to a designated Roth account, the Committee shall provide to the distributee a statement indicating the first year of the Five-Taxable-Year Period for the distributee and the
portion of such distribution that is non-taxable. If the distribution is not a direct rollover to a designated Roth account, the beginning date of the Five-Year-Taxable Period cannot be carried over to a
designated Roth account. The Plan Administrator shall, within a reasonable time after the distirbutee’s request, provide to the distributee a statement indicating the beginning date of the Five-Taxable-Year Period and the portion of such
distribution that is non-taxable. 

  
 56 








 ARTICLE X 

VALUATION OF ACCOUNTS 

For purposes of payment of a Participant’s Distributable Benefit following a Severance for any reason or any other distributions or
withdrawals under this Plan, the value of a Participant’s Accounts shall be determined in accordance with rules prescribed by the Committee, subject, however, to the following provisions: 

(a) Subject to subsections 10(b) and 10(c) below, in the case of Normal Retirement or other Severance including death or Total
and Permanent Disability, the value of a Participant’s Accounts under the Plan shall be determined by reference to the Valuation Date immediately following both (i) the occurrence of an event entitling the Participant to a distribution,
and (ii) the receipt by the Committee of the completed application of the Participant (or his Beneficiary) for payment of the Participant’s Distributable Benefit with respect to such event. 

(b) The value of a Participant’s Accounts shall be increased or decreased (as appropriate) by any contributions,
withdrawals or distributions properly allocable under the terms of this Plan to his Accounts that occurred on or after the applicable Valuation Date or which, for any other reason were not otherwise reflected in the valuation of his Accounts on such
Valuation Date. 
 (c) Notwithstanding any provision of this Plan to the contrary, a Participant’s Accounts, to the
extent held in the Perspecta Stock Fund, shall be distributed solely in shares of Stock (with payment of cash in lieu of any fractional share), unless the Participant elects to receive the Participant’s entire distribution in cash. The number
of shares so distributable shall be the number of shares credited to the Participant’s Accounts held in the Perspecta Stock Fund and such additional shares as may be purchased with the Participant’s allocable share of non-Stock assets of the Perspecta Stock Fund (the value of such non-Stock assets to be determined in accordance with principles consistent with subsections 10(a) and 10(b)
above, and the number of shares to be purchased with such non-Stock assets to be determined in accordance with such rules of general application as the Committee may adopt from time to time). Similar
provisions shall apply to a Participant’s Accounts held in the DXC Stock Fund.

Committee from time to time, and all such members shall be appointed or removed by the Board of Directors. 
 (c) For
purposes of ERISA Section 402(a), the Committee shall be the Named Fiduciary of this Plan. 
 (d) Notwithstanding the
foregoing, a Trustee with whom Plan assets have been placed in trust or an Investment Manager appointed pursuant to Section 11.4 may be granted exclusive authority and discretion to manage and control all or any portion of the assets of the
Plan. 
 11.2 Committee Powers. The Committee shall have all powers necessary to supervise the administration of
the Plan and control its operations. In addition to any powers and authority conferred on the Committee elsewhere in the Plan or by law, the Committee shall have, by way of illustration but not by way of limitation, the following powers and
authority: 
 (a) To allocate fiduciary responsibilities (other than trustee responsibilities) among the Named Fiduciaries
and the Trustee and to designate one or more other persons (including the Trustee) to carry out fiduciary responsibilities (other than trustee responsibilities). The term “trustee responsibilities” as used herein shall have the meaning set

and capricious manner. 
 11.3 Correcting Administrative Errors. If, with respect to any Plan Year, an
administrative error results in a Participant’s Account not being properly credited with the amounts of contributions, allocations, or earnings or an Eligible Employee is erroneously omitted, solely for the purpose of placing the

Committee may in its discretion allocate or reallocate existing contributions, allocations, or earnings among the Accounts of affected Participants, to the extent allowed by law. If an administrative error results in an amount being credited to a
Participant’s Account or any other individual, including a person who is not an Eligible Employee, who is not entitled thereto, corrective action may be taken by the Committee in its discretion, including but not limited to forfeit amounts
erroneously credited, reallocate such amounts among other Participants, or take such other corrective action as is appropriate under the circumstances. To the extent amounts contributed by a Participating Employer under this Section are attributable
to lost earnings, such contributions shall not be deemed to be annual additions under the Plan. In all events, such corrections may be corrected through the use of the IRS Employee Plans Compliance Resolution System, the Department of Labor
Voluntary Fiduciary Correction Program, or any other similar program of the IRS, or Department of Labor, or other applicable agency. 

11.4 Investment Managers.

applicable law and in particular in accordance with ERISA Section 404(a)(1).

Committee, in which event the Committee shall notify the Trustee of this action and the name or names of the designated members. The Trustee, Company, a Participating Employer, Participants, Beneficiaries, and any other party dealing with the

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. 
 12.2 Merger Restriction.
Notwithstanding any other provision in this Article, this Plan shall not in whole or in part merge or consolidate with, or transfer its assets or liabilities to any other plan unless each affected Participant in this Plan would receive a benefit

then terminated).

 13.4 Trustee’s Duties on Termination. 

(a) On or before the effective date of termination of this Plan, the Trustee shall proceed as soon as possible, but in any

chargeable to the Trust Fund, and after setting aside a reasonable reserve for expenses and liabilities (absolute or contingent) of the Trust, the Committee shall make required allocations of items of income and expense to the Accounts.

contributions are not required under the Plan for that year, shall not constitute a complete discontinuance of contributions to the Plan. 

  
 67 








 ARTICLE XIV 

APPLICATION FOR BENEFITS 

14.1 Application for Benefits. The Plan Administrator may require any person claiming benefits under the Plan to
submit an application thereof, together with such documents and information as the Plan Administrator may require. In the case of any person suffering from a disability which prevents the claimant from making personal application for benefits, the
Plan Administrator shall permit another person acting on his behalf to submit the application. 
 14.2
Action-on Application. 
 (a) Within ninety days following receipt of an
application and all necessary documents and information, the Plan Administrator or its authorized delegate reviewing the claim shall furnish the claimant with written notice of the decision rendered with respect to the application. If special
circumstances require an extension of time for processing the claim and written notice is given to the claimant of such extension, and such notice describes the circumstances requiring the extension and the date the Plan Administrator expects to
render a final decision, then a decision shall be rendered not later than one hundred eighty days after receipt of a request for review. 

(b) In the case of a denial of the claimant’s application, the written notice shall set forth: 

(i) The specific reasons for the denial, with reference to the Plan provisions upon which the denial is based; 

(ii) A description of any additional information or material necessary for 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 14.3 below, and must exhaust such administrative procedures prior to seeking any other form of relief. 

14.3 Appeals. 

(a) General. 

(i) A claimant who does not agree with the decision rendered with respect to his application may appeal the decision to the
Plan Administrator. 
 (ii) The appeal shall be made, in writing, within sixty (60) days after the date of notice of the
decision with respect to the application.

day period provided in Section 14.2 above, then the appeal shall be made within sixty (60) days after the expiration of the ninety (90) day period. 

(b) The claimant may request that his application be given full and fair review by the Plan Administrator. The claimant may
review all pertinent documents and submit issues and comments in writing in connection with the appeal. 
 (c) The decision
of the Plan Administrator shall be made promptly, and not later than sixty 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 days after receipt of a request for review. 

(d) The decision on review shall be in writing and shall include specific reasons for the decision, written in a manner
calculated to be understood by the claimant with specific reference to the pertinent Plan provisions upon which the decision is based. 

14.4 Disability Claims. The provisions of this Section 14.4 shall apply to claims based on a Total and
Permanent Disability pursuant to Section 9.3. 
 (a) Any review of an appeal of a denied claim must meet the following
standards: the review does not afford deference to the initial adverse benefit determination; the review is conducted by an appropriate named fiduciary who is nether the party who made the initial adverse benefit determination that is the subject of
the appeal nor a subordinate of such party; the review provides that the appropriate named fiduciary shall consult with health care professionals with appropriate training and experience in the field of medicine involved in the medical judgment in
deciding the appeal of an adverse benefit determination that is based in whole or in part on a medical judgment; and the review provides, upon the claimant’s request, for the identification of the medical or vocational experts whose advice was
obtained in connection with the claimant’s adverse benefit determination, without regard to whether the advice was relied upon in making the determination. 

(b) The 90-day period described in Section 14.2 and subsection 14.3(a) above shall
be shortened to 45 days. The 45-day period may be extended by 30 days if the Plan Administrator determines the extension is necessary because of circumstances outside the Plan’s control, and the claimant
is notified prior to the end of the 45-day period. If prior to the end of the 30-day extension period, the Plan Administrator determines that additional time is
necessary, the period may be extended for a second 30-day period, provided the claimant is notified prior to the end of the first 30-day extension period and such notice
specifies the circumstances requiring the extension and the date as of which the Plan expects to render a decision. 
 (c)
The 60-day period described in subsection 14.3(a) shall be extended to 180 days. 

  
 69 








 (d) The 60-day period described in
subsection 14.3(c) above shall be shortened to 45 days. The 45-day period may be extended by an additional 45 days if the Plan Administrator determines the extension is necessary because of circumstances
outside the Plan’s control, and the claimant is notified prior to the end of the initial 45-day period. 

(e) With respect to any claim filed on or after April 1, 2018 based on a Total and Permanent Disability, the provisions of
this Section 14.4(e) shall apply in addition to the other provisions of Section 14.4: 
 (i) The notice of denial

 (1) A discussion of the decision, including an explanation of the basis for
disagreeing with or not following: 
 (A) The views presented by the claimant to the Plan of health care professionals
treating the claimant and vocational professionals who evaluated the claim; 
 (B) The views of medical or vocational
experts whose advice was obtained on behalf of the Plan in connection with a claimant’s adverse benefit determination, without regard to whether the advice was relied upon in making the benefit determination; and 

(C) A disability determination regarding the claimant presented by the claimant to the Plan made by the Social Security
Administration. 
 (2) If the adverse benefit determination is based on a medical necessity or experimental treatment or
similar exclusion or limit, either an explanation of the scientific or clinical judgment for the determination, applying the terms of the Plan to the claimant’s medical circumstances, or a statement that such explanation will be provided free
of charge upon request. 
 (3) Either the specific internal rules, guidelines, protocols, standards or other similar
criterion of the Plan relied upon in making the adverse determination or, alternatively, a statement that such rules, guidelines, protocols, standards or other similar criterion of the Plan do not exist. 

(4) A statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies
of, all documents, records, and other information relevant to the claimant’s claim for benefits. 
 (ii) With respect to

 ARTICLE XV 

LIMITATIONS ON CONTRIBUTIONS 

15.1 General Rule. 

(a) Notwithstanding anything to the contrary contained in this Plan, in accordance with the requirements of Code
Section 415 and the final regulations issued thereunder (which are hereby incorporated by reference), and except to the extent permitted under Code Section 414(v), if applicable, the total Annual Additions that may be contributed or
allocated under this Plan to a Participant’s Accounts for any Limitation Year shall not exceed the lesser of: 
 (i)
$55,000 (as adjusted at the same time and in the same manner as under Code Section 415(d)); or 
 (ii) 100% of the
Participant’s 415 Compensation for such Limitation Year. 
 The 415 Compensation limit referred to above shall not apply
to any contribution for medical benefits after separation from service (within the meaning of Code Section 401(h) or 419A(f)(2)) that is otherwise treated as an Annual Addition. 

(b) For purposes of this Article 15, the Company has elected a “Limitation Year” corresponding to the Plan Year. 

15.2 Annual Additions. For purposes of Section 15.1, the term “Annual Additions” shall mean, for any
Plan Year, the sum of (i) the amount credited to the Participant’s Accounts from Participating Employer contributions for such Plan Year; (ii) any Employee Contributions for the Plan Year; (iii) any amounts described in Code
Section 415(l)(1) or 419(A)(d)(2); and (iv) any amounts described in Code Section 414(v) and subsection 4.1(c) of the Plan. The term “Employee Contributions,” for purposes of the preceding sentence, shall mean amounts
considered contributed by the Employee and which do not qualify for tax deferral treatment under Code Section 401(k). 
 15.3
Other Defined Contribution Plans. If a Participating Employer or an Affiliated Company is contributing to any other defined contribution plan (as defined in Code Section 415(i)) for its Employees, some or all of whom
may be Participants in this Plan, then the total Annual Additions limits specified in Section 15.1 shall be adjusted as follows: 

(a) First, if the Participant is participating in another tax-qualified defined
contribution plan maintained by any Participating Employer or an Affiliated Company (as modified by the application of Code Section 415(h)) within the same Limitation Year, and the provisions of such other defined contribution plan explicitly
require that the annual additions (within the meaning of Code Section 415(c)(2)) of such defined contribution plan be reduced in such a situation, the otherwise applicable limitation on annual additions (within the meaning of Code
Section 415(c)(2)) under such other defined contribution plan for that Limitation Year shall be first reduced by the amount of Annual Additions allocated under the Plan for that Limitation Year; and 

  
 73 








 (b) Second, the Annual Additions limits specified in Section 15.1 shall be
reduced by the amount of any annual additions (within the meaning of Code Section 415(c)(2)) a Participant receives as a participant in another tax-qualified defined contribution plan maintained by any
Participating Employer or Affiliated Company (as modified by the application of Code Section 415(h)), aside from such plans referenced in subsection 15.3(a). 

15.4 Correction of Excess Annual Additions. If the limitations with respect to Annual Additions (within the meaning
of Code Section 415) set forth in this Article 15 are exceeded for any Participant, then the Plan shall correct such excess in accordance with the Employee Plans Compliance Resolution System (EPCRS) as set forth in Revenue Procedure 2016-51 or any superseding guidance. 
 15.5 Correction of Excess Amounts. Any
excess Compensation Deferral Contributions by a Participant and any excess Matching Contributions on behalf of a Participant for any Plan Year shall be corrected in the manner described in Section 15.4. 

15.6 Affiliated Company. For purposes of this Article 15, the status of an entity as an Affiliated Company shall be
determined by reference to the percentage tests set forth in Code Section 415(h).

 ARTICLE XVI 

RESTRICTION ON ALIENATION 

16.1 General Restrictions Against Alienation. 

(a) The interest of any Participant or Beneficiary 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 and Beneficiary 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 or Beneficiary 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 or Beneficiary 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 or Beneficiary. 
 (b) In the event any person attempts to take
any action contrary to this Article 16, that action shall be void and the Company, a Participating Employer, the Committee, the Trustees and all Participants and their Beneficiaries, 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 16.1 shall be interpreted and applied by
the Committee in accordance with the requirements of Code Section 401(a)(13) as construed and interpreted by authoritative judicial and administrative rulings and regulations. 

16.2 Nonconforming Distributions Under Court Order. 

(a) In the event that a court with jurisdiction over the Plan and the Trust Fund shall issue an order or render a judgment
requiring that all or part of a Participant’s interest under the Plan and in the Trust Fund be paid to a Spouse, former Spouse and/or children of the Participant by reason of or in connection with the marital dissolution and/or marital
separation of the Participant and the Spouse, and/or some other similar proceeding involving marital rights and property interests, then notwithstanding the provisions of Section 16.1, the Committee may, in its absolute discretion, direct the
applicable Trustee to comply with that court order or judgment and distribute assets of the Trust Fund in accordance therewith. 

(b) The Committee’s decision with respect to compliance with any such court order or judgment shall be made in its
absolute discretion and shall be binding upon the Trustee and all Participants and their Beneficiaries; provided, however, that the Committee in the exercise of its discretion shall not make payments in accordance with the terms of an order which is
not a “qualified domestic relations order” or which the Committee determines would jeopardize the continued qualification of the Plan and Trust under Code Section 401. 

  
 75 








 (c) Neither the Plan, the Company, a Participating Employer, the Committee nor
the Trustee shall be liable in any manner to any person, including any Participant or Beneficiary, for complying with any such court order or judgment. 

(d) Nothing in this Section 16.2 shall be interpreted as placing upon the Company, a Participating Employer, the Committee
or any Trustee any duty or obligation to comply with any such court order or judgment. The Committee may, if in its absolute discretion it deems it to be in the best interests of the Plan and the Participants, determine that any such court order or
judgment shall be resisted by means of judicial appeal or other available judicial remedy, and in that event the Trustee shall act in accordance with the Committee’s directions. 

(e) The Committee shall adopt procedures and provide notifications to a Participant and alternate payees in connection with a
“qualified domestic relations order,” to the extent required under Code Section 414(p). 

  
 76 








 ARTICLE XVII 

PLAN AMENDMENTS 

17.1 Amendments. The Company may at any time, and from time to time, amend in whole or in part any or all of the
provisions of the Plan. Notwithstanding the foregoing, 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 5.3; 

(b) To have any retroactive effect so as to deprive any Participant or Beneficiary of any Vested Interest to which he would be
entitled under this Plan if his employment were terminated immediately before the amendment, to the extent so doing would contravene Code Section 411(d)(6); 

(c) To eliminate or reduce a subsidy or early retirement benefit or an optional form of benefit to the extent so doing would
contravene Code Section 411(d)(6); or 
 (d) To increase the responsibilities or liabilities of a Trustee or an
Investment Manager without his written consent.

forfeited at such time. These forfeitures shall be disposed of according to rules prescribed by the Committee, which rules shall be consistent with applicable law. 

(iv) The Committee shall prescribe such rules as it may deem necessary or appropriate with respect to the notice and forfeiture
rules stated above.

 ARTICLE XIX 

TOP-HEAVY PLAN RULES 

19.1 Application of Article XIX. 

(a) This Article XIX shall apply only if the Plan is Top-Heavy, as defined below. If,
as of any Top-Heavy Determination Date, as defined below, the Plan is Top-Heavy, the provisions of Section 19.4 shall take effect as of the first day of the Plan
Year next following the Top-Heavy Determination Date and shall continue to be in effect until the first day of any subsequent Plan Year following a Top-Heavy
Determination Date as of which it is determined that the Plan is no longer Top-Heavy. 

(b) For purpose of determining whether the Plan is Top-Heavy in any given year, Catch-Up Contributions for that Plan Year shall not be taken into account. However, Catch-Up Contributions for prior years shall be taken into account. Thus, Catch-Up Contributions from prior years shall be included in the accrued benefit that is used to determine whether the Plan is Top-Heavy under Section 19.3. This
paragraph is intended to comply with Code Section 414(r) and shall be interpreted to comply therewith, and with any regulations or other guidance issued thereunder. 

19.2 Definitions Concerning Top-Heavy Status. 

In addition to the definitions set forth in Article II, the following definitions shall apply for purposes of this Article XIX, and shall be
interpreted in accordance with the provisions of Code Section 416 and the Treasury Regulations thereunder: 
 (a)
“Aggregation Group” means a group of Employer Plans consisting of each Employer Plan in the Required Aggregation Group and each other Employer Plan selected by the Company for inclusion in the Aggregation Group that would not, by
its inclusion, prevent the group of Employer Plans included in the Aggregation Group from continuing to meet the requirements of Code Sections 401(a)(4) and 410. 

(b) “Annual Compensation” means, for any Plan Year, Compensation as defined in Section 2.11 for such Plan
Year. 
 (c) “Employer Plan” means any tax-qualified plan of the
Company. 
 (d) “Key Employee” means any employee of the Company who satisfies the criteria set forth in
Code Section 416(i)(1). 
 (e) “Required Aggregation Group” means one of more Employer Plans comprising
each Employer Plan in which a Key Employee is a participant and each Employer Plan that enables any Company Plan in which a Key Employee is a participant to meet the requirements of Code Sections 401(a)(4) or 410. 

  
 81 








 (f) “Top-Heavy” means
the Plan is included in an Aggregation Group under which, as of the Top-Heavy Determination Date, the sum of the present value of the cumulative accrued benefits of the Key Employees under all defined benefit
plans in the Aggregation Group and the aggregate value of the accounts (excluding Rollover Accounts, except to the extent permitted by applicable Treasury Regulations) of Key Employees under all defined contribution plans in the Aggregation Group
exceeds 60 percent of the analogous sum determined for all employees. The determination of whether the Plan is Top-Heavy shall be made in accordance with Code Section 416(g)(2)(8) and the Treasury
Regulations thereunder. 
 (g) “Top-Heavy Determination Date” means
the December 31 immediately preceding the Plan Year for which the determination is made. 
 (h) “Top-Heavy Ratio” means the percentage calculated in accordance with paragraph (f) and Code Section 416(g)(2) and the Treasury Regulations thereunder. 

(i) “Top-Heavy Year” means a Plan Year for which the Plan is Top-Heavy. 
 19.3 Calculation of Top-Heavy
Ratio. 
 The Top-Heavy Ratio with respect to any Plan Year shall be determined in accordance
with the following rules: 
 (a) Determination of Accrued Benefits. The accrued benefit of any current Participant
shall be calculated, as of the most recent valuation date that is within a 12-month period ending on the Top-Heavy Determination Date, as if the Participant had
voluntarily terminated employment as of such valuation date. Such valuation date shall be the same valuation date used for computing plan costs for purposes of the minimum funding provisions of Code Section 412. 

(b) Aggregation. The Plan shall be aggregated with all Employer Plans included in the Aggregation Group. 

19.4 Effect of Top-Heavy Status. 

(a) Minimum Contribution. Notwithstanding anything else contained in the Plan, and subject to the provisions of this
Section 19.4(a) as of the last day of each Top-Heavy Year, the Employer and Affiliates shall make, for each Participant who is not a Key Employee (without regard to such Participant’s Hours of
Service or level of Compensation), (1) the Company contributions they otherwise would have made under the Plan for such Top-Heavy Year, or if greater, (2) contributions for such Top-Heavy Year that, when added to the contributions made by the Company for such Participant (and any forfeitures allocated to his account) for such Top-Heavy Year under all
other defined contribution plans for the Company, aggregate the lessor of (x) three percent of his Annual Compensation or (y) the percentage at which contributions (including before-tax Contributions
or other contributions attributable to a salary reduction or similar arrangement) are made for the Key Employee for whom such percentage is the highest for the Top-Heavy Year. 

  
 82 








 (b) Accelerated Vesting. A Participant who has completed at least three
years of service and who is credited with an Hour of Service in a Top-Heavy Year shall have a nonforfeitable interest in his Accounts as of the last day of any Top-Heavy
Year. For purposes of determining whether the Participant’s interest in his Accounts is nonforfeitable under the preceding sentence, Code Sections 411(a)(3)(B) and (a)(3)(D) (relating to suspension of benefits and forfeitures upon withdrawal of
mandatory contributions, respectively) shall not apply. 
 19.5 Effect of Discontinuance of
Top-Heavy Status. 
 If, for any Plan Year after a
Top-Heavy Year, the Plan is no longer Top-Heavy, the provisions of Section 19.4 shall not apply with respect to such Plan Year, except that: 

(a) The accrued benefit of any Participant shall not be reduced on account of the operation of this Section 19.5; 

(b) Each Participant shall remain fully vested in any portion of the Participant’s accrued benefit that was fully vested
before the Plan ceased to be Top-Heavy; and 
 (c) Any Participant who was a
Participant in a Top-Heavy Year and who has completed at least three years of service as of the first day of the Plan Year in which the Plan is no longer Top-Heavy may
elect to remain subject to the provisions of Section 19.4(b). 
 19.6 Intent of Article XIX. 

This Article XIX is intended to satisfy the requirements imposed by Code Section 416 and shall be construed in a manner that shall
effectuate this intent. This Article XIX shall not be construed in a manner that would impose requirements on the Plan that are more stringent than those imposed by Code Section 416. 

  
 83 








 ARTICLE XX 

ESOP 

“Stock” in this Article refers to both Perspecta Stock and DXC Stock. When the DXC Stock Fund ceases to exist, “Stock” in
this Article shall refer only to Perspecta Stock. 
 20.1 ESOP Accounts. It is intended that the Accounts held in
the Trust Fund in Stock under the Plan in both the Perspecta Stock Fund and the DXC Stock Fund shall constitute a separate Employee Stock Ownership Plan (“ESOP”) within the meaning of Code Section 4975(e)(7) with respect to
Participants who are currently or were formerly employed by a Participating Employer with respect to which Stock is considered to be “Employer Securities” within the meaning of that term under Code Section 409(l); provided, however,
that a Participant who is employed by a Participating Employer or Affiliate or is a member of a designated employee group (in both cases as set forth in Appendix I hereof) shall not be considered a Participant in the ESOP during the time period he
is employed by such ineligible employer or is a member of such ineligible group but only with respect to contributions or accretions to his Account occurring during such period of ineligibility. A Participant in the ESOP who ceases to be eligible
for the ESOP due to the transfer of his employment to an employer that fails to be a Participating Employer with respect to which Stock is considered to be “Employer Securities” within the meaning of that term under Code
Section 409(l) or that is excluded from participation in the ESOP under Appendix I hereof shall continue to be a Participant in the ESOP with respect to his Account balance held in the Perspecta Stock Fund or DXC Stock Fund) prior to the date
on which his employment transfer caused such Participant to cease to be eligible for the ESOP. However, contributions (and earnings and gains thereon) made to the Plan on behalf of a transferred Participant on or after the date on which the
Participant ceases to be eligible for the ESOP shall not become part of the ESOP during any period in which the Participant remains employed by an ineligible employer or is a member of an ineligible group in accordance with Appendix I hereof or is
otherwise excludable from the ESOP with respect to post-transfer contributions and earnings. Assets held in the ESOP shall be invested primarily in Stock in accordance Code Section 4975(e)(7). Except as otherwise provided in this Article 20,
the provisions of the Plan shall apply to and are made a part of the ESOP. A Beneficiary of a Participant in the ESOP whose Account balance was considered to be part of the ESOP as of the Participant’s death shall also be considered a
Participant in the ESOP to the extent such Account balance (including reinvested dividends on Stock in the Perspecta Stock Fund (or DXC Stock Fund) remains in the Perspecta Stock Fund (or DXC Stock Fund) following the Participant’s death. An
alternate payee pursuant to a qualified domestic order, as defined in Code Section 414(p), whose Account balance was considered to be part of the ESOP as of the effective date of the qualified domestic relations order shall also be considered a
Participant in the ESOP to the extent such Account balance (including reinvested dividends on Stock in the Perspecta Stock Fund or DXC Stock Fund) remains in the Perspecta Stock Fund (or DXC Stock Fund) following the effective date of the qualified
domestic relations order. Notwithstanding the foregoing, the DXC Stock Fund is intended to be part of the ESOP solely for purposes of continuing the Participant opportunity for the dividend (and company deductions) feature of Plan Section 20.4
and shall be administered with this intention. 

  
 84 








 20.2 Exempt Loan. In the event the ESOP enters into an exempt loan,
the following provisions shall apply: 
 (a) The proceeds of such exempt loan shall be used (i) to acquire qualifying
employer securities, (ii) to repay such loan, and/or (iii) to repay a prior exempt loan. No security acquired with the proceeds of an exempt loan may be subject to a put, call or other option, or
buy-sell or similar arrangement while held by and when distributed from the ESOP. The terms of each exempt loan shall meet the applicable requirements of Treasury Regulations
Section 54.4975-7(b), including the requirements: (a) that the loan bear a reasonable rate of interest, be for a definite period (rather than payable on demand), and be without recourse against the
Plan, and (b) that the only assets of the Plan that may be given as collateral is Stock purchased with the proceeds of that loan or with the proceeds of a prior exempt loan. The interest rate of an exempt loan and the price of the
securities to be acquired with the proceeds of an exempt loan may not be such that plan assets are drained off. An exempt loan must be primarily for the benefit of the Participants and Beneficiaries of the Plan. Proceeds of an exempt loan
must be used within a reasonable time to acquire Perspecta Stock, to repay the exempt loan, or to repay a prior exempt loan. No person entitled to payment under an exempt loan shall have any right to assets of the ESOP other than collateral
given for the exempt loan, contributions (other than contributions of Perspecta Stock) made to repay such exempt loan, and earnings attributable to such collateral and the investment of such contributions. Payments made with respect to an
exempt loan during a Plan Year must not exceed an amount equal to the sum of such contributions and earnings during such Plan Year less such payments in prior years. Such contributions and earnings must be accounted for separately in the books
of account of the ESOP until the exempt loan is repaid. In the event of a default on an exempt loan, the assets transferred from the Plan may not exceed the amount of the default. If the lender is a disqualified person, the assets
transferred may not exceed the amount then due under the payment schedule of the exempt loan. In the event that a Participant incurs a forfeiture, assets in the Participant’s Accounts other than Stock acquired with an exempt loan will be
forfeited before such Stock is forfeited. 
 (b) Put Options. The Company shall issue a “Put Option” to each
Participant (or each Participant’s Beneficiary) who receives a distribution of Stock if, at the time of such distribution, Stock is not then readily tradable on an established market, as defined in Code Section 408(h) and the regulation
thereunder. The Put Option shall permit the Participant (or the Participant’s Beneficiary) to sell such Stock at its then fair market, as determined by an independent appraiser in accordance with the provisions of Section 20.2(e)(iv), to
the Company at any time during the sixty-day period commencing on the date the Stock was distributed to the Participant (or the Participant’s Beneficiary), and, if not exercised within that period, the
Put Option will temporarily lapse. The Plan Administrator shall extend the sixty-day period referred to in the immediately preceding sentence if such an extension is necessary in order for the Stock to be
valued by an independent appraiser as of the applicable Valuation Date coincident with or immediately preceding the date the Stock was distributed to the recipient. As of the annual Valuation Date coincident with or immediately following the Plan
Year in which such temporary lapse of the Put Option occurs, the independent appraiser shall determine the value of the Stock in accordance with the provisions of Section 20.2(e)(iv), and the Plan Administrator shall notify each distribute who
did not exercise the initial Put Option prior to its temporary lapse in the preceding Plan Year of the revised value of the Stock. The time during which the Put Option may be exercised shall recommence on the date such notice or revaluation is given
and shall permanently terminate sixty days thereafter. The Trustee may be permitted by the Company to purchase Stock put to the Company under a Put Option. Payment for Stock sold pursuant to a Put Option shall be made, as determined in the
discretion of the Plan Administrator, in the following forms: 

  
 85 








 (i) If a Participant’s Account invested in the ESOP is distributed in a
total distribution (that is, a distribution within one taxable year of the balance to the credit of the Participant’s Account invested in the ESOP), then payment for such Stock may be made with a promissory note that provides for substantially
equal annual installments commencing within 30 days from the date of the exercise of the Put Option and over a period not exceeding five years, with interest payable at a reasonable rate (as determined by the Plan Administrator) on any unpaid
installment balance, with adequate security provided, and without penalty for any prepayment of such installments; or 
 (ii)
In a lump sum no later than 30 days after such Participant exercises the Put Option. 
 Except as otherwise provided in this
Section, no shares of Stock held or distributed by the Trustee may be subject to a put, call or other option, or buy-sell or similar arrangement. The provisions of this Section are nonterminateable, and shall
continue to be applicable to shares of Stock even if the Accounts held in the Trust Fund in Stock under the Plan cease to be an ESOP within the meaning of Code Section 4975(e)(7). 

(c) The rights and protections as stated in subsections 20.2(a) and (b) are
non-terminable. 
 (d) All assets acquired by the ESOP with the proceeds of an exempt
loan will be added to and maintained in a suspense account. Stock acquired through an exempt loan shall be released from the suspense account as the exempt loan is repaid. For each Plan Year until the exempt loan is fully repaid, the number of
shares of Stock released from the suspense account shall equal the number of unreleased shares immediately before such release for the current Plan Year multiplied by the “Release Fraction.” As used herein, the Release Fraction shall be a
fraction the numerator of which is the amount of principal and interest paid on the exempt loan for such current Plan Year and the denominator of which is the sum of the numerator plus the principal and interest to be paid on such exempt loan for
all future years during the duration of the term of such loan (determined without reference to any possible extensions or renewals thereof). 

(e) Allocations, Forfeitures and Valuations. 

(i) As at the end of each Plan Year, the ESOP must consistently allocate to the Participant’s Accounts non-monetary units representing Participants’ interests in assets withdrawn from the suspense account. 

  
 86 








 (ii) Interest with respect to securities acquired with the proceeds of an exempt
loan must be allocated as income of the ESOP, except to the extent that the ESOP provides for the use of income from such securities to repay the loan. 

(iii) If a portion of a Participant’s Account is forfeited, qualifying Company securities allocated under this subsection
20.2(e) must be forfeited only after other assets. 
 (iv) Valuations must be made in good faith and based on fair market
value. The fair market value of Company securities that are not readily tradable on an established securities market shall be determined by an independent appraiser, as defined in Code Section 401(a)(28)(C), in accordance with the provisions of
ERISA Section 3(18). In the case of a transaction between the Plan and a disqualified person as described in Code Section 4975(e)(2), value must be determined as of the date of the transaction. 

(v) Notwithstanding any provision of this Plan to the contrary, if shares of Stock are sold to the Plan by a shareholder in a
transaction for which special tax treatment is elected by such shareholder (or his representative) pursuant to Code Section 1042, no allocation of such shares (or other assets in lieu thereof) may accrue or be allocated directly or indirectly
under any plan of the Company meeting the requirements of Code Section 401(a) to the Accounts of: 
 (1) any person who
owns (after the application of Code Section 318(a)) more than 25 percent of any class of the outstanding securities of the companies included in a controlled group of corporations, within the meaning of Code Section 414(b), that
includes the Company; or 
 (2) during the Nonallocation Period, any person who sold shares to the Plan, and any person who
is related to such shareholder (within the meaning of Code Section 267(b)), but excluding lineal descendants of such shareholder as long as no more than 5 percent of the aggregate amount of all Stock sold by such shareholder or any other
relative of the lineal descendant in a transaction to which Code Section 1042 applies is allocated to lineal descendants of such shareholder during the Nonallocation Period. 

(3) The term “Nonallocation Period” means the period beginning on the date of sale and ending on the later of ten
years after the date of sale or the date of the allocation attributable to the final payment on the Acquisition Loan incurred with respect to the sale. An election under Code Section 1042 may not be made if the Company is an S corporation at
the time of sale, but if such an election is made for a time when the Company is a C corporation the restrictions of this subsection shall continue to apply if the Company becomes an S corporation. 

  
 87 








 (f) Accounts are Distributable Only in Stock. If securities acquired with
the proceeds of an exempt loan available for distribution consist of more than one class, a Distributee must receive substantially the same proportion of each such class. In the event such distributable securities are not readily tradeable on an
established market, a Participant has the right to require the Company to repurchase such securities within the time periods and in accordance with the methods described in Code Sections 409(h)(5) and (6). Income held by the ESOP for a 2-year period or longer must be distributed under the rule described in the first sentence of this subsection 20.2(f). 

20.3 Distributions. Notwithstanding any provision of the Plan to the contrary, any portion of a Participant’s
Accounts attributable to Stock acquired by the ESOP which has not been invested in accordance with Section 7.3 shall, at the election of the Participant and his Spouse (if required under subsection 9.4(b)(i)), be distributed not later than one
(1) year after the close of the Plan Year (i) in which occurs the Participant’s Severance by reason of attainment of Normal Retirement Date, Total and Permanent Disability, or death, or (ii) which is the fifth Plan Year following
the Plan Year in which occurs the Participant’s Severance for any reason other than those listed under (i) above, provided that the Participant is not reemployed prior to the close of such fifth Plan Year. It is intended that this
Section 20.3 complies with the distribution rule set forth in Code Section 409(o)(1) with respect to amounts invested in the ESOP. 

20.4 Treatment of Dividends. 

(a) Whenever cash dividends are declared in respect of Stock held by the ESOP, Participants who are considered to be
Participants in the ESOP on the dividends record date may make an election in respect of Stock deemed to be held in their Accounts under the ESOP no later than the ex-dividend date either to receive such
dividends in a cash distribution from the ESOP or to have such dividends reinvested for their benefit in Stock to be held in the Perspecta Stock Fund (or DXC Stock Fund) of the ESOP. Such election shall be offered and administered in accordance with
Code Section 404(k)(2)(A)(iii), related Treasury Regulations and other official IRS guidance, including IRS Notice 2002-2. Participants who fail to make an affirmative election to receive a cash
distribution of dividends shall be deemed to have made an election to have such dividends reinvested for their benefit in Stock to be held in the Perspecta Stock Fund (or DXC Stock Fund) of the ESOP. Notwithstanding anything to the contrary herein,
dividends paid in respect of Stock held by the ESOP shall be fully vested at all times. Dividends paid in respect of Stock held by the ESOP shall be distributed to Participants or reinvested as soon as practicable following the dividends payment
date in accordance with the election procedure described herein. Such dividends shall not be subject to the nondiscrimination provisions of the Code, including Code Sections 401(a)(4), 401(k), 401(m), 410(b), shall not be considered Annual Additions
for purposes of Code Section 415 nor shall they be subject to the top heavy rules of Code Section 416. For purposes of this Section 20.4, a Beneficiary or an alternate payee described in Section 20.1 of the Plan shall be eligible
to make the election described herein with respect to Stock held in the Beneficiary’s Account that is considered to be part of the ESOP no later than the ex-dividend date. 

  
 88 








 (b) Upon the Separation, Participants who have invested in the DXC Stock Fund
prior to the Separation are entitled to the Special Dividend (i.e., the Perspecta Stock dividend) on the same basis as other DXC shareholders. Perspecta Stock and DXC Stock each will be considered an “applicable employer security” as set
forth in Code Section 404(k). A Participant’s election under Section 20.4(a) of the Plan (or as in effect under the DXC MAP as of the Participant’s transfer to this Plan as of May 1, 2018) that is in effect on the ex-dividend date for the Special Dividend will be applied to the Special Dividend. If the Participant has not made an election (or has not made an election under the DXC MAP that is carried over to this Plan) to
receive his or her dividends in cash before the Special Dividend ex-dividend date, the Special Dividend will automatically be paid into the Plan. 

20.5 Acquisition Loans. An “Acquisition Loan” means the issuance of notes, a series of notes or other
installment obligations incurred by the Trustee, in accordance with the Trust, in connection with the purchase of Stock. An “exempt loan” is an Acquisition Loan that complies with the terms of Treasury Regulation Section 54.4975-7(b), Section 20.2, and of this paragraph. The term “Financed Shares” means shares of Stock acquired by the Trustee with the proceeds of an Acquisition Loan. The terms of each
Acquisition Loan shall meet the applicable requirements of Treasury Regulations Section 54.4975-7(b), including the requirements: (a) that the loan bear a reasonable rate of interest, be for a
definite period (rather than payable on demand), and be without recourse against the Plan, and (b) that the only assets of the Plan that may be given as collateral are Financed Shares purchased with the proceeds of that loan or with the
proceeds of a prior Acquisition Loan. The interest rate of an Acquisition Loan and the price of the securities to be acquired with the proceeds of an Acquisition Loan may not be such that Plan assets are drained off. An Acquisition Loan must be
primarily for the benefit of the Participants and Beneficiaries of the Plan. Proceeds of an Acquisition Loan must be used within a reasonable time to acquire Stock, to repay the Acquisition Loan, or to repay a prior Acquisition Loan. Proceeds of an
Acquisition Loan may not be used to purchase life insurance. No person entitled to payment under an Acquisition Loan shall have any right to assets of the Plan other than collateral given for the Acquisition Loan, contributions (other than
contributions of Stock) made to repay such Acquisition Loan, and earnings attributable to such collateral and the investment of such contributions. Payments made with respect to an Acquisition Loan during a Plan Year must not exceed an amount equal
to the sum of such contributions and earnings during such Plan Year less such payments in prior years. Such contributions and earnings must be accounted for separately in the books of account of the Plan until the exempt loan is repaid. In the event
of a default of an Acquisition Loan, the assets transferred from the Plan may not exceed the amount of the default. If the lender is a disqualified person, the assets transferred may not exceed the amount then due under the payment schedule of the
Acquisition Loan. Notwithstanding any other provision in this Plan to the contrary, assets may be transferred upon default of an Acquisition Loan to a lender who is a disqualified person up to the limits specified in this paragraph.

notice to the Committee, make a withdrawal from his After-Tax Merged Account of any amount up to the entire amount thereof. The maximum amount subject to withdrawal under this Section 21.3 shall be
determined as of the Valuation Date immediately following the Committee’s determination authorizing the withdrawal. A Participant who makes a withdrawal under this Section 21.3 shall not be eligible to again make a withdrawal under this
Section 21.3 prior to the first anniversary of the date the Participant’s most recent withdrawal under this Section 21.3 was distributed to him. 

21.4 Effect on Other Plan Provisions. Nothing contained in this Article 21 shall be deemed to create any right in
any Participant to make after-tax employee contributions to this Plan nor shall this Article 21 create any additional rights beyond those required to effectuate the creation and administration of the After-Tax Merged Accounts.
