INTRODUCTION

Engility Corporation (the “Company”) establishes the Engility Master Savings Plan (the “Plan”) to provide retirement benefits to eligible employees of Engility Corporation and its affiliated business units. The Plan is adopted effective June 29, 2012.

The Plan is established in connection with the distribution by L-3 Communications Holdings, Inc. to its public shareholders of 100 percent of the common shares of Engility Holdings, Inc. Effective on July 18, 2012, Engility Corporation will be a subsidiary of Engility Holdings, Inc., and will continue to be the sponsor of this Plan.

The Engility Master Savings Plan is comprised of two parts. The first part consists of this Plan document, which sets forth the provisions that apply to all eligible employees. This Plan document is effective as of June 29, 2012.

The second part consists of Schedule B which set forth the specific benefits, rights and features that apply to employees of each of the Engility Corporation business units.

The benefits payable to or on behalf of a Participant in accordance with the provisions of this Plan shall not be affected by the terms of any amendment to the Plan adopted after such Participant’s employment terminates, unless the amendment expressly provides otherwise.

The Plan is intended to be qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”) and its Trust is intended to be tax-exempt under Code Section 501(a). Participants are entitled to receive benefits in accordance with the terms of the Plan in effect on the date they terminate employment or retire.

(a) If a portion of a Participant’s Accounts under the Plan is attributable to amounts transferred from a money purchase pension plan, and the Participant elects an annuity form of payment and the Participant dies before the Annuity Starting Date, the Participant’s vested Account balance shall be used to purchase a Qualified Preretirement Survivor Annuity for the Participant’s spouse. A Qualified Preretirement Survivor Annuity is an annuity for the life of the Participant’s spouse.

(b) A Participant may waive the Qualified Preretirement Survivor Annuity form of payment. Any election to waive the Qualified Preretirement Survivor Annuity must be consented to by the Participant’s spouse in the same manner provided for in Section 10.8(b) and (c). A Participant may revoke a waiver at any time before the payment of benefits commences without the consent of the spouse, provided that a new waiver shall require a new spousal consent.

(c) If the Participant dies and the Qualified Preretirement Survivor Annuity has not been waived, the surviving spouse may, prior to the time that annuity payments begin, waive the Qualified Preretirement Survivor Annuity form of benefit and elect an alternative form of payment provided under the Plan.

ARTICLE XI—SPECIAL TOP-HEAVY PROVISIONS

11.1 TOP-HEAVY RULES

In the event the Plan is or becomes Top-Heavy (as defined in Section 11.2 hereof) in any Plan Year, the provisions of this Article shall apply and shall supersede any conflicting provisions in the Plan for such Plan Year.

11.2 DEFINITIONS

As used in this Article, the following terms shall have the meanings set forth below:

(a) “Determination Date” means with respect to any Plan Year the last day of the preceding Plan Year, and for the first Plan Year, the first day of such Plan Year.

(b) “Key Employee” means an Eligible Employee or former Eligible Employee (including a deceased employee) of the Company or an Affiliate who, at any time during the Plan Year that includes the Determination Date was an officer having greater than $130,000 (as adjusted under Section 416(i)(1) of the Code for Plan Years beginning after December 31, 2002), a 5-percent owner of the Company or an Affiliate, or a 1-percent owner of the Company or an Affiliate. For this purpose, annual compensation means compensation within the meaning of Section 415(c)(3) of the Code. The determination of who is a Key Employee will be made in accordance with Section 416(i)(1) of the Code and the applicable regulations and other guidance of general applicability issued thereunder.

(c) “Non-Key Employee” means any employee who is not a Key Employee and includes an employee who is a former Key Employee.

(d) This Plan shall be “Top-Heavy” for any Plan Year if the provisions of any of the following apply:

(1) the Top-Heavy Ratio for the Plan exceeds 60% and the Plan is not part of any Required Aggregation Group of Plans or Permissive Aggregation Group of Plans;

(2) the Plan is a part of a Required Aggregation Group of Plans (but is not part of a Permissive Aggregation Group of Plans) and the Top-Heavy Ratio for the Required Aggregation Group of Plans exceeds 60%; or

(3) the Plan is a part of a Required Aggregation Group of Plans and part of a Permissive Aggregation Group of Plans and the Top-Heavy Ratio for the Permissive Aggregation Group of Plans exceeds 60%.

(e) “Top-Heavy Ratio” means a fraction: (1) the numerator of which is the sum of the amount credited to accounts under the Plan and any other defined contribution plan maintained by the Company or an Affiliate which is required or permitted to be taken into account for all Key Employees and the Present Value of accrued

Engility Master Savings Plan

40

benefits under any defined benefit plan maintained by the Company or Affiliate which is required or permitted to be taken into account for all Key Employees, and (2) the denominator of which is the sum of the amount credited to the accounts under such defined contribution plans for all Participants and the Present Value of accrued benefits under such defined benefit plans for all Participants. In determining the Top-Heavy Ratio, a Participant’s accrued benefit in a defined benefit plan must be determined using the method uniformly used for accrual purposes for all plans of the Company and Affiliate. If there is no such uniform method, the accrued benefit is to be determined as if it accrued not more rapidly than under the slowest rate of accrual permitted under Code Section 411(b)(1)(C).

For purposes of this definition: (A) the amount credited to accounts and the Present Value of accrued benefits shall be determined as of the last day of the most recent Plan Year that falls within or ends with the 12-month period ending on the Determination Date; (B) the amount credited to the accounts and accrued benefits of a Participant who is a Non-Key Employee but who was a Key Employee in a prior year will be disregarded; (C) the amount credited to the accounts and accrued benefits of any individual who has not performed services for the Employer or an Affiliate for the one-year period ending on the Determination Date shall not be taken into account; and (D) the present value of accrued benefits and the account balances of an employee as of the Determination Date shall be increased by the distributions made with respect to the employee under the Plan and any plan aggregated with the Plan under section 416(g)(2) of the Code during the 1-year period ending on the Determination Date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under section 416(g)(2)(A)(i) of the Code. In the case of a distribution made for a reason other than severance from employment, death, or disability, this provision shall be applied by substituting “5-year period” for “1-year period.”

(f) “Required Aggregation Group of Plans” means (1) each qualified plan of the Company or an Affiliate (including a terminated plan) in which at least one Key Employee participates, and (2) any other qualified plan of the Company or an Affiliate which enables a plan described in (1) to meet the requirements of Section 401(a)(4) or 410 of the Code.

(g) “Permissive Aggregation Group of Plans” means the Required Aggregation Group of Plans plus any other plan or plans of the Company or an Affiliate which, when considered as a group with the Required Aggregation Group of Plans, would continue to satisfy the requirements of Sections 401(a)(4) and 410 of the Code.

(h) “Present Value” of accrued benefits under any defined benefit plan maintained by the Company or an Affiliate shall mean an actuarial equivalent lump sum amount based on the Pension Benefit Guaranty Corporation factors and assumptions.

11.3 MINIMUM CONTRIBUTION

(a) Except as otherwise provided in subsection (b), for any Plan Year in which the Plan is Top-Heavy, the Employer contributions (and forfeitures) allocated on behalf of any Participant who is a Non-Key Employee (exclusive of any Pre-Tax Contributions on his behalf) shall not be less than 3% of such Participant’s Section 415 earnings (as defined in Section 5.5(d) hereof) for such Plan Year. However, should the sum of the Employer’s contributions, including Pre-Tax Contributions, and forfeitures allocated to the Account of each Key Employee for such Top-Heavy Plan Year be less than 3% of each Key Employee’s Compensation, the sum of the Employer’s contributions and forfeitures allocated to the Account of each Non-Key Employee shall be equal to the largest percentage allocated to the Account of each Key Employee. The percentage allocated to the Account of any Key Employee shall be equal to the ratio of the sum of the Employer’s contribution and forfeitures allocated on behalf of such Key Employee divided by the Compensation for such Key Employees. The minimum allocation provided for in this Section shall be determined without regard to any contribution to or benefit payable under the Social Security law and shall apply even though under other Plan provisions the Participant would not otherwise be entitled to receive an allocation or would have received a lesser allocation for the applicable Plan Year for any reason. Matching Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) and this Section. Matching Contributions that are used to satisfy the minimum contributions requirements shall be treated as matching contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code.

(b) The minimum allocation provided in subsection (a) shall not apply to any Participant who was not an Eligible Employee on the last day of the applicable Plan Year or to any Participant to the extent such Participant is covered under any other plan of the Company or an Affiliate which provides for the minimum allocation of Employer contributions and/or accrual of retirement benefits.

11.4 TOP-HEAVY VESTING SCHEDULE

(a) Effective as of the first day of the first Plan Year in which this Plan is Top-Heavy (the “Top-Heavy Effective Date”), the nonforfeitable interest of each Participant in the portion of his or her Employer Contribution Account shall be determined as follows, provided, however, that if the Appendix provides a faster vesting schedule, such vesting schedule shall continue to apply:

2		20	%
3		40	%
4		60	%
5		80	%
6 years or more		100	%

(b) Such vesting schedule shall remain in effect for all Plan Years commencing on and after the Top-Heavy Effective Date even though the Plan may not be Top-Heavy for any such Plan Year. Notwithstanding the foregoing provisions of this Section, this Section shall not apply to the benefit of any Participant whose Termination of Employment occurred prior to the Top-Heavy Effective Date.

ARTICLE XIII—AMENDMENT AND TERMINATION

13.1 PLAN AMENDMENTS

The Company, by action of the Board of Directors, may at any time modify or amend the Plan, in whole or in part, provided, however, that no such amendment shall make it possible for any of the assets of the Trust Fund to be used for or diverted to purposes other than for the exclusive benefit of Participants and their Beneficiaries, or cause a cut-back in Participants’ benefits under the Plan within the meaning of Section 411(d)(6) of the Code. Any such amendment shall be by an instrument in writing approved by the Board of Directors and executed by an officer who is authorized by the Company to sign amendments to the Plan.

ARTICLE XIV—GENERAL PROVISIONS

Nothing contained in the Plan shall be construed as a contract of employment between the Employer or the Company and any Eligible Employee, and the Plan shall not afford an Eligible Employee a right to continued employment with the Employer or the Company.

14.4 ALIENATION AND QDROS

Engility Master Savings Plan

46

representatives) of the Committee’s determination. “Alternate Payee” shall mean any spouse, former spouse, child or other dependent of a Participant recognized by a proper domestic relations order as having a right to receive all, or a portion of, a Participant’s benefits under the Plan, as prescribed under Code Section 414(p).

14.5 NOTICE TO THE COMMITTEE

14.6 MERGERS AND TRANSFERS

The Board of Directors shall have the power to fully or partially merge the Plan with any other tax-qualified plan or transfer assets to, or accept assets from, any other tax-qualified plan. In the event of any merger or consolidation of the Plan with, or a transfer of the assets and liabilities of the Plan to, any other plan, each Participant shall receive a benefit under such other plan (if such other plan were terminated immediately after such merger, consolidation or transfer) which is equal to or greater than the benefit the Participant would have been entitled to receive under the Plan (if the Plan had been terminated immediately prior to such merger, consolidation or transfer).

14.11 DEEMED DISTRIBUTIONS OF UNVESTED AMOUNTS

In the event of a Participant’s Termination of Employment before he or she has any vested interest in his or her Employer Contribution Account, if any, the Participant shall be deemed to have received a distribution of his or her balance as of the Termination of Employment date, in the amount of the unvested portion of his or her Employer Contribution Account. The amount of this deemed distribution shall be zero. Following this deemed distribution, the Participant shall have no remaining benefit under the Plan attributable to his or her Employer Contribution Account.

14.12 HEADINGS

Section headings are provided only for the convenience of the reader. Section headings shall not be considered in interpreting this document.

14.13 MISSING PAYEES

A Participant (or, if deceased, his or her Beneficiary if entitled to Benefits under the Plan) is obligated to keep the Plan Administrator informed as to his or her current address at all times. In the event that a Participant or Beneficiary or other recipient of Benefits cannot be located with reasonable efforts by the end of the second calendar year following the date when Benefits are first payable under the Plan, an amount equal to the Benefit payable may be forfeited. If the Participant or Beneficiary or other recipient of Benefits subsequently makes a claim for these forfeited Benefits, at any time, then the amount forfeited will be reinstated, without interest, and paid as soon as practicable.

14.14 CHANGES IN VESTING SCHEDULE

If the vesting schedule is amended in any way that directly or indirectly affects the computation of the Participant’s nonforfeitable percentage such that contributions made subsequent to the amendment will vest more slowly as a result of the amendment, or if the Plan is deemed to be amended by an automatic change to or from a Top-Heavy vesting schedule, each Participant with at least three years of Service with the Employer may elect, within a reasonable period after the adoption of the amendment or change, to have the nonforfeitable percentage computed under the applicable Appendix without regard to such amendment or change. The period during which the election may be made shall commence with the date the amendment is adopted or deemed to be made and shall end on the latest of:

(a) 60 days after the amendment is adopted;

(b) 60 days after the amendment becomes effective; or

Engility Master Savings Plan

48

(c) 60 days after the Participant is issued written notice of the amendment by the Employer or Plan Administrator.

If a vesting schedule is amended, or if the Plan is determined to be Top-Heavy, then the Participants with (1) at least one Hour of Service during the Plan Year for which the change is made and (2) three years of Service with an Employer may elect within a reasonable period, as provided by Code Section 411(a)(10), either the new or former vesting schedule.

The Committee hereby specifically delegates to the Trustee the responsibility to be liable for income tax withholding, and to withhold the appropriate amount from any payment made from the Trust to any payee under the provisions of applicable law and regulation.

14.16 COMMON TRUST FUNDS

The Plan adopts and includes the provisions of any group or common trust fund in which the Trust participates, but only as long as such group or common trust fund remains qualified under Section 401(a), and exempt from taxation under Section 501(a), of the Code in accordance with Revenue Ruling 81-100.

SCHEDULE A

MINIMUM REQUIRED DISTRIBUTIONS

Section 1. General Rules.

(a) Effective Date. Notwithstanding any other provision of the Plan to the contrary, the provisions of this Appendix will apply for purposes of determining required minimum distributions for calendar years beginning with the 2003 calendar year.

(b) Treasury Regulations Incorporated by Reference. All distributions required under this Appendix will be determined and made in accordance with the Treasury regulations under section 401(a)(9) of the Code.

Section 2. Time and Manner of Distribution.

(a) Required Beginning Date. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s Required Beginning Date.

(b) Death of Participant Before Distributions Begin. If the Participant dies before distributions begin, the Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary and the surviving spouse dies after the Participant but before distributions to the surviving spouse begin, this Section 2(b) will apply as if the surviving spouse were the Participant.

(c) Forms of Distribution. Unless the Participant’s interest is distributed in a single sum on or before the Required Beginning Date, as of the first Distribution Calendar Year, distributions will be made in accordance with Sections 3 and 4 of this Schedule.

Section 3. Required Minimum Distributions During Participant’s Lifetime.

(a) Amount of Required Minimum Distribution For Each Distribution Calendar Year. During the Participant’s lifetime, the minimum amount that will be distributed for each Distribution Calendar Year is the lesser of:

(1) the quotient obtained by dividing the Participant’s Account Balance by the distribution period in the Uniform Lifetime Table set forth in Treas. Reg. §1.401(a)(9)–9, using the Participant’s age as of the Participant’s birthday in the Distribution Calendar Year; or

(2) if the Participant’s sole Designated Beneficiary for the Distribution Calendar Year is the Participant’s spouse, the quotient obtained by dividing the Participant’s Account Balance by the number in the Joint and Last Survivor Table set forth in §1.401(a)(9)–9, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the Distribution Calendar Year.

Section 4. Required Minimum Distributions After Participant’s Death.

(a) Death On or After Date Distributions Begin.

(1) Participant Survived by Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the longer of the remaining Life Expectancy of the Participant or the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as follows:

(A) The Participant’s remaining Life Expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

(B) If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, the remaining Life Expectancy of the surviving spouse is calculated for each Distribution Calendar Year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year. For Distribution Calendar Years after the year of the surviving spouse’s death, the remaining Life Expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year.

(C) If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, the Designated Beneficiary’s remaining Life Expectancy is calculated using the age of the beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year.

(2) No Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is no Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the Participant’s remaining Life Expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

(b) Death Before Distributions Begin. If the Participant dies before distributions begin, the Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

For distributions beginning before the Participant’s death, the first Distribution Calendar Year is the calendar year immediately preceding the calendar year which contains the Participant’s Required Beginning Date. For distributions beginning after the Participant’s death, the first Distribution Calendar Year is the calendar year in which distributions are required to begin under Section 2(b). The required minimum distribution for the Participant’s first Distribution Calendar Year will be made on or before the Participant’s Required Beginning Date. The required minimum distribution for other Distribution Calendar Years, including the required minimum distribution for the Distribution Calendar Year in which the Participant’s Required Beginning Date occurs, will be made on or before December 31 of that Distribution Calendar Year.

(c) Life Expectancy. Life Expectancy as computed by use of the Single Life Table in Treas. Reg. §1.401(a)(9)–9.

The Account Balance for the valuation calendar year includes any amounts rolled over or transferred to the Plan either in the valuation calendar year or in the Distribution Calendar Year if distributed or transferred in the valuation calendar year.
