SECTION 3. Eligibility.

Any one or more Awards may be granted to any Employee, Director or any other non-Employee who provides services to or on behalf of the Corporation or any of its Subsidiaries, who is designated by the Committee to receive an Award.

SECTION 4. Awards.

(a) Type of Awards. The Committee may from time to time grant any of the following types of Awards, either singly, in tandem or in combination with other Awards:

(1) Nonqualified Stock Options. A Nonqualified Stock Option is an Award in the form of an option to purchase Stock that is not intended to comply with the requirements of Code Section 422. The exercise price of each Nonqualified Stock Option granted under this Plan shall not be less than the Fair Market Value of the Stock on the date that the Option is granted.

(2) Incentive Stock Options. An Incentive Stock Option is an Award in the form of an option to purchase Stock that is intended to comply with the requirements of Code Section 422 or any successor section thereof. The exercise price of each Incentive Stock Option granted under this Plan shall not be less than the Fair Market Value of the Stock on the date the Option is granted. If a Participant on the date an Incentive Stock Option is granted owns, directly or indirectly within the meaning of Code Section 424(d), stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Corporation, the exercise price per share of the Incentive Stock Option shall not be less than one hundred and ten percent (110%) of the Fair Market Value per share of the Stock at the time of grant, and such Incentive Stock Option shall not be exercisable after the expiration of five (5) years from the date such Incentive Stock Option is granted. To the extent that the aggregate Fair Market Value of Stock with respect to which one or more incentive stock options first become exercisable by a Participant in any calendar year exceeds $100,000, taking into account both Stock subject to Incentive Stock Options under this Plan and stock subject to incentive stock options under all other plans of the Corporation or of other entities referenced in Code Section 422(d)(1), the options shall be treated as Nonqualified Stock Options. For this purpose, the Fair Market Value of the Stock subject to options shall be determined as of the date the Options were granted.

(3) Stock Appreciation Rights. A Stock Appreciation Right is an Award in the form of a right to receive, upon surrender of the right, but without other payment, an amount based on the appreciation in the value of the Stock or the Option over a base price established in the Award, payable in cash, Stock or such other form or combination of forms of payout, at times and upon conditions (which may include a Change in Control), as may be approved by the Committee. The minimum base price of a Stock Appreciation Right granted under this Plan shall not be less than the Fair Market Value of the underlying Stock on the date the Stock Appreciation Right is granted.

(4) Restricted Stock. Restricted Stock is an Award of issued shares of Stock of the Corporation (other than Minimum Ownership Stock) that are subject to restrictions on transfer and/or such other restrictions on incidents of ownership as the Committee may determine.

4

(5) Other Share-Based Awards. The Committee may from time to time grant Awards under this Plan that provide the Participants with Stock or the right to purchase Stock, or provide other incentive Awards (including, but not limited to, Minimum Ownership Stock, phantom stock or units, performance stock or units, bonus stock, dividend equivalent units, or similar securities or rights) that have a value derived from the value of, or an exercise or conversion privilege at a price related to, or that are otherwise payable in shares of Stock. The Awards shall be in a form determined by the Committee, provided that the Awards shall not be inconsistent with the other express terms of this Plan applicable to such Awards.

(b) Special Performance-Based Awards. Without limiting the generality of the foregoing, any of the type of Awards listed in Section 4(a) may be granted as awards that satisfy the requirements for “performance-based compensation” within the meaning of Code Section 162(m) (“Performance-Based Awards”), the grant, vesting, exercisability or payment of which may depend on the degree of achievement of the Performance Goals relative to preestablished targeted levels for the Corporation or any of its Subsidiaries, divisions or other business units. Performance-Based Awards shall be subject to the requirements of clauses (1) through (7) below, except that notwithstanding anything contained in this Section 4(b) to the contrary, any Option or Stock Appreciation Right intended to qualify as a Performance-Based Award shall not be subject to the requirements of clauses (2), (4), (5) and (6) below (with such Awards hereinafter referred to as a “Qualifying Option” or a “Qualifying Stock Appreciation Right”, respectively). An Award that is intended to satisfy the requirements of this Section 4(b) shall be designated as a Performance-Based Award at the time of grant.

(1) Eligible Class. The eligible class of persons for Awards under this Section 4(b) shall be all Employees.

(2) Performance Goals. The performance goals for any Awards under this Section 4(b) (other than Qualifying Options and Qualifying Stock Appreciation Rights) shall be, on an absolute or relative basis, one or more of the Performance Goals. The Committee shall establish the Performance Goals and the Performance Periods for which they must be satisfied in order for a Participant to receive any portion of the Award. The specific performance target(s) with respect to Performance Goal(s) must be established by the Committee no later than the last day of the First Quarter of a given Performance Period (or such other date as may be required or permitted under Section 162(m) of the Code) and while the performance relating to the Performance Goal(s) remains substantially uncertain. The Committee may establish different performance objectives for each Performance Period, and may provide for multiple, overlapping Performance Periods hereunder. The Committee may provide, at the time when performance objectives are established with respect to a Performance Period (or at such later date as may be permitted under Section 162(m) of the Code), for the adjustment of such performance objectives as it deems equitable in recognition of unusual or non-recurring events affecting the Corporation, changes in applicable tax laws or accounting principles, or such other factors as the Committee may determine to be appropriate, including, without limitation, the gain or loss on disposal of a business segment.

5

(3) Individual Limits. The maximum number of shares of Stock subject to all Qualifying Options and Qualifying Stock Appreciation Rights granted during a calendar year to any Employee shall be 700,000, and the maximum number of shares of Stock or Share Units that are issuable under other Performance-Based Awards granted during a calendar year to an Employee shall be 700,000, in each case subject to adjustment as provided in Section 7. Awards that are cancelled during the year shall be counted against these limits to the extent required by Code Section 162(m).

(4) Committee Certification. Before any Performance-Based Award under this Section 4(b) (other than Qualifying Options and Qualifying Stock Appreciation Rights) is paid, the Committee must certify in writing (by resolution or otherwise) that the applicable Performance Goal(s) and any other material terms of the Performance-Based Award were satisfied; provided, however, that a Performance-Based Award may be paid without regard to the satisfaction of the applicable Performance Goal in the event of the Participant’s death or permanent disability or in the event of a Change in Control as provided in Section 7(b).

(5) Terms and Conditions of Awards; Committee Discretion to Reduce Performance Awards. The Committee shall have discretion to determine the conditions, restrictions or other limitations, in accordance with the terms of this Plan and Code Section 162(m), on the payment of individual Performance-Based Awards under this Section 4(b). The Committee may reserve the right to reduce the amount payable in accordance with any standards or on any other basis (including the Committee’s discretion), as the Committee may impose.

(6) Adjustments for Material Changes. To the extent set forth by the Committee in an Award Agreement or otherwise, in the event of (i) a change in corporate capitalization, a corporate transaction or a complete or partial corporate liquidation, (ii) any extraordinary gain or loss or other event that is treated for accounting purposes as an extraordinary item under generally accepted accounting principles, (iii) any material change in accounting policies or practices affecting the Corporation and/or the Performance Goals or targets, or (iv) any other unusual or nonrecurring event, the Committee shall make adjustments to the Performance Goals and/or targets, applied as of the date of the event, and based solely on objective criteria, so as to neutralize, in the Committee’s judgment, the effect of the event on the applicable Performance-Based Award.

(7) Interpretation. Except as specifically provided in this Section 4(b), the provisions of this Section 4(b) shall be interpreted and administered by the Committee in a manner consistent with the requirements for exemption of Performance-Based Awards granted to Executive Officers as “performance-based compensation” under Code Section 162(m) and regulations and other interpretations issued by the Internal Revenue Service thereunder.

6

(c) Non-Employee Directors. The Board may provide that all or a portion of a Non-Employee Director’s annual retainer, meeting fees and/or other awards or compensation as determined by the Board, be payable (either automatically or at the election of a Non-Employee Director) in the form of Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock or Other Share-Based Awards, including unrestricted Stock and Share Units. The Board shall determine the terms and conditions of any such Awards, including the terms and conditions which shall apply upon a termination of the Non-Employee Director’s service as a member of the Board, and shall have full power and authority in its discretion to administer such Awards, subject to the terms of the Plan and applicable law.

SECTION 5. Shares of Stock and Share Units Available Under Plan.

(a) Aggregate Limits on Shares and Share Units. (i) Subject to adjustment as provided in Section 5(b), Section 5(c) or Section 7, as of the Restatement Effective Date the maximum number of shares of Stock that may be granted pursuant to all Awards under the plan is 2,570,000, minus any shares of Stock subject to (x) Awards granted after March 26, 2013 under the Plan and (y) awards granted after March 26, 2013 under the Prior Directors Plan (the “Share Reserve”); and (ii) the maximum number of shares of Stock that may be issued pursuant to all Awards of Incentive Stock Options is 2,570,000.

(b) Share Usage for Full Value Awards. Solely for purposes of calculating the number of shares of Stock available for Award grants pursuant to Section 5(a)(i), each share of Stock subject to Awards (or awards under the Prior Directors Plan) granted after March 26, 2013 (other than Awards of Options and Stock Appreciation Rights, which shall continue to be counted as one (1) share) shall be counted as one and sixty eight one-hundredths (1.68) shares.

(c) Addbacks of Shares and Share Units. After March 26, 2013, any unexercised, unconverted or undistributed portion of any expired, cancelled, terminated or forfeited Award, or award under the Prior Directors Plan, shall again be available for grants of Awards under Section 5(a), whether or not the Participant has received benefits of ownership (such as dividends or dividend equivalents or voting rights) during the period in which the Participant’s ownership was restricted or otherwise not vested. After March 26, 2013, to the extent an Award, or an award under the Prior Directors Plan, is settled in cash in lieu of issuing shares of Stock subject thereto, such shares shall be deemed to constitute Share Units (and not shares of Stock subject to or issued pursuant to an Award) for purposes of the limits set forth in Section 5(a) and any shares subject to such an Award may again be available for grants of Awards under the Plan. In the event that after March 26, 2013, withholding tax liabilities arising from an Award other than an Option or Stock Appreciation Right, or an award other than an option or stock appreciation right under the Prior Plans, are satisfied by the tendering of shares (either actually or by attestation) or by the withholding of shares by the Corporation, the shares so tendered or withheld shall again be available for grants of Awards under the Plan. The foregoing provisions of this Section 5(c) shall be added back on the basis set forth in Section 5(d) below. For the avoidance of doubt, after March 26, 2013, the following shares of Stock shall not become available for Awards under the Plan: (1) shares tendered by Participants or withheld by the Corporation as full or partial payment to the Corporation upon exercise of Options or other Awards granted under the Plan, or options or other awards under the Prior Directors Plan; (2) shares of Stock reserved for issuance upon the grant of Stock Appreciation Rights, to the extent the number of reserved shares exceeds

7

the number of shares actually issued upon exercise of the Stock Appreciation Rights under the Plan, or stock appreciation rights under the Prior Directors Plan; (3) shares withheld by, or otherwise remitted to, the Corporation to satisfy a Participant’s tax withholding obligations upon the exercise of Options or Stock Appreciation Rights under the Plan, or options or stock appreciation rights under the Prior Directors Plan; and (4) shares of Stock reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of Options under the Plan or options granted under the Prior Directors Plan.

(d) Any shares of Stock that again become available for grant pursuant to Section 5(c) after March 26, 2013 shall be added back as (i) one (1) share for every one (1) share subject to Options or Stock Appreciation Rights granted under the Plan or options or stock appreciation rights granted under the Prior Directors Plan, and (ii) as 1.68 shares for every one (1) share subject to Awards other than Options or Stock Appreciation Rights granted under the Plan or awards other than options or stock appreciation rights granted under the Prior Directors Plan.

(e) Treasury Shares; No Fractional Shares. The Stock which may be issued (which term includes Stock reissued or otherwise delivered) pursuant to an Award under this Plan may be treasury or authorized but unissued Stock or Stock acquired, subsequently or in anticipation of a transaction under this Plan, in the open market or in privately negotiated transactions to satisfy the requirements of this Plan. No fractional shares shall be issued but fractional interests may be accumulated and any such accumulated fractional interests shall be rounded down to the nearest whole share.

(f) Consideration. The Stock issued under this Plan may be issued (subject to Section 10(d)) for any lawful form of consideration, the value of which equals the par value of the Stock or such greater or lesser value as the Committee, consistent with Sections 10(d) and 4(a)(1), (2) and (3), may require.

(g) Purchase or Exercise Price; Withholding. The exercise or purchase price (if any) of the Stock issuable pursuant to any Award and any withholding obligation under applicable tax laws shall be paid at or prior to the time of the delivery of such Stock in cash or, subject to the Committee’s express authorization and the restrictions, conditions and procedures as the Committee may impose, any one or combination of (i) cash, (ii) the delivery of shares of Stock, or (iii) a reduction in the amount of Stock or other amounts otherwise issuable or payable pursuant to such Award. In the case of a payment by the means described in clause (ii) or (iii) above, the Stock to be so delivered or offset shall be determined by reference to the Fair Market Value of the Stock on the date as of which the payment or offset is made, and any shares of Stock so tendered or withheld for taxes will be at the minimum statutory rate.

(h) Cashless Exercise. The Committee may also permit the exercise of the Award and payment of any applicable withholding tax in respect of an Award by delivery of written notice, subject to the Corporation’s receipt of a third party payment in full in cash (or in such other form as permitted under Section 5(f)) for the exercise price and the applicable withholding at or prior to the time of issuance of Stock, in the manner and subject to the procedures as may be established by the Committee.

8

(i) Limitations on Director Grants. The maximum number of shares of Stock subject to Awards granted during a calendar year to any Non-Employee Director, excluding any cash fees deferred in the form of Restricted Stock or Other Share-Based Awards during such calendar year, shall not exceed $400,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes).

SECTION 6. Award Agreements.

Each Award under this Plan shall be evidenced by an Award Agreement in a form approved by the Committee setting forth the number of shares of Stock or Share Units, as applicable, subject to the Award, and the price (if any) and term of the Award and, in the case of Performance-Based Awards, the applicable Performance Goals, if any. The Award Agreement shall also set forth (or incorporate by reference) other material terms and conditions applicable to the Award as determined by the Committee consistent with the limitations of this Plan.

(a) Incorporated Provisions. Award Agreements shall be subject to the terms of this Plan and shall be deemed to include the following terms:

(1) Transferability: Unless otherwise designated by the Committee, an Award shall not be assignable or transferable, except by will or by the laws of descent and distribution, and during the lifetime of a Participant the Award shall be exercised only by such Participant or by his or her guardian or legal representative; provided, that the Committee shall not have the authority to provide for transfers for consideration to persons unrelated to the Participant. An Award exercisable after the death of a Participant may be exercised by the legatees, personal representatives or distributees of the Participant. The designation of a Beneficiary hereunder shall not constitute a transfer prohibited by the foregoing provisions.

(2) Rights as Stockholder: A Participant shall have no rights as a holder of Stock with respect to any unissued securities covered by an Award until the date the Participant becomes the holder of record of these securities. Except as provided in Section 7, no adjustment or other provision shall be made for dividends or other stockholder rights, except to the extent that the Award Agreement provides for dividend equivalents or similar economic benefits.

(3) Withholding: The Participant shall be responsible for payment of any taxes or similar charges required by law to be withheld from an Award or an amount paid in satisfaction of an Award and these obligations shall be paid by the Participant on or prior to the payment of the Award. In the case of an Award payable in cash, the withholding obligation shall be satisfied by withholding the applicable amount and paying the net amount in cash to the Participant. In the case of an Award paid in shares of Stock, a Participant shall satisfy the withholding obligation as provided in Section 5(g).

(4) Maximum Term of Awards. No Option or Stock Appreciation Right may be exercised or converted to any extent or remain outstanding and unexercised, unconverted or unvested more than ten years after the date such Option or Stock

9

Appreciation Right was initially granted. The Committee may provide, at or after grant, that the period of time over which an Option, other than an Incentive Stock Option, or Stock Appreciation Right may be exercised shall be automatically extended if on the scheduled expiration of such Award, the Participant’s exercise of such Award would violate applicable securities law; provided, however, that during the extended exercise period the Option or Stock Appreciation Right may only be exercised to the extent such Award was exercisable in accordance with its terms immediately prior to such scheduled expiration date; provided further, however, that such extended exercise period shall end not later than thirty (30) days after the exercise of such Option or Stock Appreciation Right first would no longer violate such laws.

(b) Other Provisions. Award Agreements may include other terms and conditions as the Committee shall approve, including but not limited to the following:

(1) Termination of Employment: A provision describing the treatment of an Award in the event of the retirement, disability, death or other termination of a Participant’s employment with or services to the Corporation, including any provisions relating to the vesting, exercisability, forfeiture or cancellation of the Award in these circumstances, subject, in the case of Performance-Based Awards, to the requirements for “performance-based compensation” under Code Section 162(m).

(2) Vesting; Effect of Termination; Change in Control: Any other terms consistent with the terms of this Plan as are necessary and appropriate to effect the Award to the Participant, including but not limited to the vesting provisions, any requirements for continued employment, any other restrictions or conditions (including performance requirements) of the Award, and the method by which (consistent with Section 7) the restrictions or conditions lapse, and the effect on the Award of a Change in Control. Unless otherwise provided by the Committee in the applicable Award Agreement, (1) the minimum vesting period for Awards of Restricted Stock shall be three years from the date of grant (or one year in the case of Restricted Stock Awards that are Performance-Based Awards) and (2) the vesting period of an Award of Restricted Stock may not be accelerated to a date that is within such minimum vesting period except in the event of the Participant’s death, permanent disability or retirement or in the event of a Change in Control; provided, however, that the foregoing limitations shall not apply to Awards to Non-Employee Directors (in their capacity as such).

(3) Replacement and Substitution: Any provisions permitting or requiring the surrender of outstanding Awards or securities held by the Participant in whole or in part in order to exercise or realize rights under or as a condition precedent to other Awards, or in exchange for the grant of new or amended Awards under similar or different terms; provided, that except in connection with an adjustment contemplated by Section 7, no such provisions of an Award Agreement shall permit a “Repricing” as defined in Section 8(d).

(4) Dividends and Dividend Equivalents: Any provisions providing for the payment of dividends or dividend equivalents on unissued shares of Stock or unpaid Share Units underlying an Award, on either a current or deferred or contingent basis, and

10

either in cash or in additional shares of Stock; provided, however, that except under the circumstances set forth in Section 7 below, dividend equivalents may not be paid with respect to Awards of Options or Stock Appreciation Rights, and any dividend or dividend equivalent rights granted with respect to Other Share-Based Awards, including performance awards and restricted stock units, shall not be paid unless and until the underlying shares of Stock to which such dividend or dividend equivalent rights relate vest.

(c) Contract Rights, Forms and Signatures. Any obligation of the Corporation to any Participant with respect to an Award shall be based solely upon contractual obligations created by this Plan and an Award Agreement. No Award shall be enforceable until the Award Agreement has been signed on behalf of the Corporation by an Executive Officer (other than the recipient) or his or her delegate. By accepting receipt of the Award Agreement, a Participant shall be deemed to have accepted and consented to the terms of this Plan and any action taken in good faith under this Plan by and within the discretion of the Committee, the Board of Directors or their delegates, including but not limited to the incorporation of any applicable clawback policy adopted by the Board or the Committee at any time. Unless the Award Agreement otherwise expressly provides, there shall be no third party beneficiaries of the obligations of the Corporation to the Participant under the Award Agreement.

SECTION 7. Adjustments; Change in Control; Acquisitions.

(a) Adjustments. If there shall occur any recapitalization, stock split (including a stock split in the form of a stock dividend), reverse stock split, merger, combination, consolidation, or other reorganization or any extraordinary dividend or other extraordinary distribution in respect of the Stock (whether in the form of cash, Stock or other property), or any split-up, spin-off, extraordinary redemption, or exchange of outstanding Stock, or there shall occur any other similar corporate transaction or event in respect of the Stock, or a sale of substantially all the assets of the Corporation as an entirety, then the Committee shall, in the manner and to the extent, if any, as it deems appropriate and equitable to the Participants and consistent with the terms of this Plan, and taking into consideration the effect of the event on the holders of the Stock:

(1) proportionately adjust any or all of:

(A) the number and type of shares of Stock and Share Units which thereafter may be made the subject of Awards (including the specific maximum limits and numbers of shares of Stock or Share Units set forth elsewhere in this Plan),

(B) the number and type of shares of Stock, other property, Share Units or cash subject to any or all outstanding Awards,

(C) the grant, purchase or exercise price, or conversion ratio of any or all outstanding Awards, or of the Stock, other property or Share Units underlying the Awards,

11

(D) the securities, cash or other property deliverable upon exercise or conversion of any or all outstanding Awards,

(E) subject to Section 4(b), the performance targets or standards appropriate to any outstanding Performance-Based Awards, or

(F) any other terms as are affected by the event; and/or

(2) provide for:

(A) an appropriate and proportionate cash settlement or distribution, or

(B) the substitution or exchange of any or all outstanding Awards, or the cash, securities or property deliverable on exercise, conversion or vesting of the Awards.

The Committee shall act prior to an event described in this paragraph (a) (including at the time of an Award by means of more specific provisions in the Award Agreement) if deemed necessary or appropriate to permit the Participant to realize the benefits intended to be conveyed by an Award in respect of the Stock in the case of an event described in paragraph (a).

(b) Change in Control. The Committee may, in the Award Agreement, provide for the effect of a Change in Control on an Award. Such provisions may include, but are not limited to any one or more of the following with respect to any or all Awards: (i) the specific consequences of a Change in Control on the Awards; (ii) a reservation of the Committee’s right to determine in its discretion at any time that there shall be full acceleration or no acceleration of benefits under the Awards; (iii) that only certain or limited benefits under the Awards shall be accelerated; (iv) that the Awards shall be accelerated for a limited time only; or (v) that acceleration of the Awards shall be subject to additional conditions precedent (such as a termination of employment following a Change in Control).

In addition to any action required or authorized by the terms of an Award, the Committee may take any other action it deems appropriate to ensure the equitable treatment of Participants in the event of a Change in Control, including but not limited to any one or more of the following with respect to any or all Awards: (i) the acceleration or extension of time periods for purposes of exercising, vesting in, or realizing gain from, the Awards; (ii) the waiver of conditions on the Awards that were imposed for the benefit of the Corporation, (iii) provision for the cash settlement of the Awards for their equivalent cash value (based solely on the Fair Market Value of the Award), as determined by the Committee, as of the date of the Change in Control; or (iv) such other modification or adjustment to the Awards as the Committee deems appropriate to maintain and protect the rights and interests of Participants upon or following the Change in Control, including the cancellation of any Options or Stock Appreciation Rights whose exercise price (or base price, as the case may be) is less than the Fair Market Value of a share of Stock on the date of the Change in Control. The Committee also may accord any Participant a right to refuse any acceleration of exercisability, vesting or benefits, whether pursuant to the Award Agreement or otherwise, in such circumstances as the Committee may approve.

Notwithstanding the foregoing provisions of this Section 7(b) or any provision in an Award Agreement to the contrary, if any Award to any Insider is accelerated to a date that is less than six months after the date of the Award, the Committee may prohibit a sale of the underlying Stock (other than a sale by operation or law in exchange for or through conversion into other securities), and the Corporation may impose legend and other restrictions on the Stock to enforce this prohibition.

(c) Change in Control Definition. For purposes of this Plan, with respect to any Award other than an Award issued pursuant to an Award Agreement that separately defines the term “change in control,” a change in control shall include and be deemed to occur upon the following events:

(1) The acquisition by any person or group (including a group within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act), other than the Corporation or any of its Subsidiaries, of beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of a majority of the combined voting power of the Corporation’s then outstanding voting securities, other than by any employee benefit plan maintained by the Corporation;

(2) The sale of all or substantially all of the assets of the Corporation or of Engility Corporation or any successor thereto;

(3) The consummation of a merger, combination, consolidation, recapitalization, or other reorganization of the Corporation with one or more other entities that are not Subsidiaries if, as a result of the consummation of such transaction less than 50 percent of the outstanding voting securities of the surviving or resulting corporation shall immediately after the event be beneficially owned in the aggregate by the stockholders of the Corporation immediately prior to the event;

(4) The election, including the filling of vacancies, during any period of 24 months or less, of 50 percent or more, of the members of the Board, without the approval of Continuing Directors, as constituted at the beginning of such period. “Continuing Directors” shall mean any director of the Corporation who either (i) is a member of the Board on July 18, 2012, or (ii) is nominated for election to the Board by a majority of the Board which is comprised of Directors who were, at the time of such nomination, Continuing Directors; or

(5) In the Committee’s sole discretion on a case-by-case basis and solely with respect to Awards granted to Employees of a Subsidiary of the Corporation, or of a business unit or division of the Corporation or such Subsidiary, (i) the sale of all or substantially all of the assets of such Subsidiary, business unit or division or (ii) the sale (including without limitation by way of merger) of a majority of the combined voting power of such Subsidiary’s then outstanding voting securities.

Notwithstanding the foregoing, unless otherwise provided in the applicable Award Agreement, with respect to Awards constituting a “deferral of compensation” subject to Section 409A of the Code, a Change in Control shall mean a “change in the ownership of the Company,” a “change

13

in the effective control of the Company,” or a “change in the ownership of a substantial portion of the assets of the Company” as such terms are defined in Section 1.409A-3(i)(5) of the Treasury Regulations.

(d) Business Acquisitions. Awards may be granted under this Plan on the terms and conditions as the Committee considers appropriate, which may differ from those otherwise required by this Plan to the extent necessary to reflect a substitution for or assumption of stock incentive awards held by employees of other entities who become employees of the Corporation or a Subsidiary as the result of a merger of the employing entity with, or the acquisition of the property or stock of the employing entity by, the Corporation or a Subsidiary (an “Acquisition”), directly or indirectly (such awards, “Substitute Awards”). Substitute Awards shall not be counted against the limitations set forth in Section 5(a) nor be added back pursuant to Section 5(c), provided that Substitute Awards issued in connection with the assumption of, or in substitution for, Incentive Stock Options shall be counted against the limits set forth in Section 5(a)(ii) of the Plan. Without limiting the foregoing, the Corporation has assumed under the Plan (and will or has issued Stock under the Plan in respect of) certain equity-based Awards originally granted by L-3 Communications Holdings, Inc. to certain current and former employees of the Corporation in connection with the tax-free spin-off transaction on July 17, 2012 that resulted in the Corporation becoming an independent, publicly-traded company, and such Awards are treated as Awards made hereunder, and not as Substitute Awards. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan; provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination.

SECTION 8. Administration.

(a) Committee Authority and Structure. This Plan and all Awards granted under this Plan shall be administered by the Compensation Committee of the Board or such other committee of the Board or subcommittee of the Compensation Committee as may be designated by the Board and constituted so as to permit this Plan to comply with the disinterested administration requirements of Rule 16b-3 under the Exchange Act and the “outside director” requirement of Code Section 162(m). The members of the Committee shall be designated by the Board. A majority of the members of the Committee (but not fewer than two) shall constitute a quorum. The vote of a majority of a quorum or the unanimous written consent of the Committee shall constitute action by the Committee.

(b) Selection and Grant. The Committee shall have the authority to determine the individuals (if any) to whom Awards will be granted under this Plan, the type of Award or Awards to be made, and the nature, amount, pricing, timing, and other terms of Awards to be made to any one or more of these individuals, subject to the terms of this Plan.

14

(c) Construction and Interpretation. The Committee shall have the power to interpret and administer this Plan and Award Agreements, and to adopt, amend and rescind related rules and procedures. All questions of interpretation and determinations with respect to this Plan, the number of shares of Stock, Options, Stock Appreciation Rights, or units or other Awards granted, and the terms of any Award Agreements, the adjustments required or permitted by Section 7, and other determinations hereunder shall be made by the Committee and its determination shall be final and conclusive upon all parties in interest. In the event of any conflict between an Award Agreement and any non-discretionary provisions of this Plan, the terms of this Plan shall govern.

(d) Express Authority to Change Terms of Awards. The Committee may, at any time, alter or amend any or all Award Agreements under this Plan in any manner that would be authorized for a new Award under this Plan, including but not limited to any manner set forth in Section 9 (subject to any applicable limitations thereunder), except that no amendment or cancellation of an Award may effect a Repricing of such Award, except in connection with an adjustment pursuant to Section 7 or with the prior approval of the Corporation’s shareholders. A “Repricing” means any of the following: (i) changing the terms of an Award to lower its exercise price or base price, (ii) cancelling an Award with an exercise price or base price in exchange for other Awards with a lower exercise price or base price, or (iii) cancelling an Award with an exercise price or base price at a time when such price is equal to or greater than the Fair Market Value of the underlying Stock in exchange for other Awards, cash or property. Without limiting the Committee’s authority under this plan (including Sections 7 and 9), but subject to any express limitations of this Plan (including the prohibitions on Repricing set forth in this Section 8(d)), the Committee shall have the authority to accelerate the exercisability or vesting of an Award, to extend the term or waive early termination provisions of an Award (subject to the maximum ten-year term under Section 6(a)(5)), and to waive the Corporation’s rights with respect to an Award or restrictive conditions of an Award (including forfeiture conditions), in any case in such circumstances as the Committee deems appropriate.

(e) Rule 16b-3 Conditions; Bifurcation of Plan. It is the intent of the Corporation that this Plan and Awards hereunder satisfy and be interpreted in a manner, that, in the case of Participants who are or may be Insiders, satisfies any applicable requirements of Rule 16b-3, so that these persons will be entitled to the benefits of Rule 16b-3 or other exemptive rules under Section 16 under the Exchange Act and will not be subjected to avoidable liability thereunder as to Awards intended to be entitled to the benefits of Rule 16b-3. If any provision of this Plan or of any Award would otherwise frustrate or conflict with the intent expressed in this Section 8(e), that provision to the extent possible shall be interpreted and deemed amended so as to avoid such conflict. To the extent of any remaining irreconcilable conflict with this intent, the provision shall be deemed disregarded as to Awards intended as Rule 16b-3 exempt Awards. Notwithstanding anything to the contrary in this Plan, the provisions of this Plan may at any time be bifurcated by the Board or the Committee in any manner so that certain provisions of this Plan or any Award Agreement intended (or required in order) to satisfy the applicable requirements of Rule 16b-3 are only applicable to Insiders and to those Awards to Insiders intended to satisfy the requirements of Rule 16b-3.

15

(f) Delegation and Reliance. The Committee may delegate to the officers or employees of the Corporation the authority to make grants hereunder and to otherwise execute and deliver those instruments and documents, to do all acts and things, and to take all other steps deemed necessary, advisable or convenient for the effective administration of this Plan in accordance with its terms and purpose, except that the Committee may not delegate any discretionary authority to grant or amend an award or with respect to substantive decisions or functions regarding this Plan or Awards as these relate to the material terms of Performance-Based Awards to Executive Officers or to the timing, eligibility, pricing, amount or other material terms of Awards to Insiders. In making any determination or in taking or not taking any action under this Plan, the Board and the Committee may obtain and may rely upon the advice of experts, including professional advisors to the Corporation. No director, officer, employee or agent of the Corporation shall be liable for any such action or determination taken or made or omitted in good faith.

(g) Exculpation and Indemnity. Neither the Corporation nor any member of the Board of Directors or of the Committee, nor any other person participating in any determination of any question under this Plan, or in the interpretation, administration or application of this Plan, shall have any liability to any party for any action taken or not taken in good faith under this Plan or for the failure of an Award (or action in respect of an Award) to satisfy Code requirements as to incentive stock options or to realize other intended tax consequences, to qualify for exemption or relief under Rule 16b-3 or to comply with any other law, compliance with which is not required on the part of the Corporation.

SECTION 9. Amendment and Termination of this Plan.

The Board of Directors may at any time amend, suspend or discontinue this Plan, subject to any stockholder approval that may be required under applicable law. Notwithstanding the foregoing, no such action by the Board or the Committee shall, in any manner adverse to a Participant other than as expressly permitted by the terms of an Award Agreement, affect any Award then outstanding and evidenced by an Award Agreement without the consent in writing of the Participant or, to the extent applicable, a Beneficiary, a Participant’s family member or a trust (or similar estate planning entity) established for the benefit of a Participant and/or one or more of the Participant’s family members entitled to an Award. Notwithstanding the above, any amendment that would (i) materially increase the aggregate number of shares of Stock or other equity interest(s) that may be issued hereunder, (ii) materially modify the requirements as to eligibility for participation in this Plan, (iii) effect a Repricing, or (iv) otherwise require shareholder approval under the listing standards of the New York Stock Exchange (or such other principal market in which the Company’s shares are traded) or any other law or regulation, shall be subject to shareholder approval.

SECTION 10. Miscellaneous.

(a) Unfunded Plans. This Plan shall be unfunded. Neither the Corporation nor the Board of Directors nor the Committee shall be required to segregate any assets that may at any time be represented by Awards made pursuant to this Plan. Neither the Corporation, the Committee, nor the Board of Directors shall be deemed to be a trustee of any amounts to be paid or securities to be issued under this Plan.

16

(b) Rights of Employees.

(1) No Right to an Award. Status as an Employee shall not be construed as a commitment that any one or more Awards will be made under this Plan to an Employee or to Employees generally. Status as a Participant shall not entitle the Participant to any additional Award.

(2) No Assurance of Employment or Other Service Relationship. Nothing contained in this Plan (or in any other documents related to this Plan or to any Award) shall confer upon any Employee or Participant any right to continue in the employ or other service of the Corporation or any Subsidiary or constitute any contract (of employment or otherwise) or limit in any way the right of the Corporation or any Subsidiary to change a person’s compensation or other benefits or to terminate the employment or services of a person with or without cause.

(c) Effective Date; Duration. This Plan has been adopted by the Board of Directors of the Corporation and will amend and restate the previous plan as set forth herein effective as of the date on which the Corporation’s public shareholders approve the Plan (the “Restatement Effective Date”). This Plan shall remain in effect until any and all Awards under this Plan have been exercised, converted or terminated under the terms of this Plan and applicable Award Agreements. Notwithstanding the foregoing, no Award may be granted under this Plan after the tenth anniversary of the date on which the Corporation’s public shareholders approve the Plan; provided, however, that any Award granted prior to such date may be amended after such date in any manner that would have been permitted hereunder prior to such date.

(d) Compliance with Laws. This Plan, Award Agreements, and the grant, exercise, conversion, operation and vesting of Awards, and the issuance and delivery of shares of Stock and/or other securities or property or the payment of cash under this Plan, Awards or Award Agreements, are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal insider trading, registration, reporting and other securities laws and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may be necessary or, in the opinion of counsel for the Corporation, advisable in connection therewith. Any securities delivered under this Plan shall be subject to such restrictions (and the person acquiring such securities shall, if requested by the Corporation, provide such evidence, assurance and representations to the Corporation as to compliance with any of such restrictions) as the Corporation may deem necessary or desirable to assure compliance with all applicable legal requirements.

(e) Awards to Non-U.S. Participants. The Committee shall have the power and authority to determine which service providers outside the United States shall be eligible to participate in the Plan. Without amending the Plan, the Committee may grant Awards to eligible persons who are foreign nationals and/or reside outside the United States on such terms and conditions different from those specified in this Plan as may in the judgment of the Committee be necessary or desirable to foster and promote achievement of the purposes of this Plan. The Committee may adopt, amend or rescind rules, procedures or sub-plans relating to the operation and administration of the Plan to accommodate the specific requirements of local laws, procedures, and practices.

17

(f) Section 409A. Notwithstanding other provisions of the Plan or any Award Agreements thereunder, no Award shall be granted, deferred, accelerated, extended, paid out or modified under this Plan in a manner that would result in the imposition of an additional tax under Section 409A of the Code upon a Participant. In the event that it is reasonably determined by the Board or Committee that, as a result of Section 409A of the Code, payments in respect of any Award under the Plan may not be made at the time contemplated by the terms of the Plan or the relevant Award agreement, as the case may be, without causing the Participant holding such Award to be subject to taxation under Section 409A of the Code, the Corporation will make such payment on the first day that would not result in the Participant incurring any tax liability under Section 409A of the Code; which, if the Participant is a “specified employee” within the meaning of the Section 409A, shall be the first day following the six-month period beginning on the date of Participant’s termination of Employment. Notwithstanding the foregoing, each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on him or her, or in respect of any payment or benefit delivered in connection with the Plan (including any taxes and penalties under Section 409A of the Code), and the Company shall not have any obligation to indemnify or otherwise hold any Participant harmless from any or all such taxes or penalties.

(g) Applicable Law. This Plan, Award Agreements and any related documents and matters shall be governed by, and construed in accordance with, the laws of the State of Delaware and applicable Federal law.

(h) Non-Exclusivity of Plan. Nothing in this Plan shall limit or be deemed to limit the authority of the Corporation, the Board or the Committee to grant awards or authorize any other compensation, with or without reference to the Stock, under any other plan or authority.

(i) Company Clawback Policy. Notwithstanding any provision of the Plan or any Award Agreement to the contrary, the Company may require the Participant to return shares of Stock (or the value of such Stock when originally released to Participant), dividends paid thereon and any other amount required by law to be returned, in the event that such repayment is required in order to comply with any Company compensation recovery (or other clawback) policy as then in effect or any laws or regulations relating to restatements of the Company’s publicly-reported financial results.
