NORTHROP GRUMMAN 2011 LONG-TERM INCENTIVE STOCK PLAN (As Amended Through December 4, 2014)

(i)    39,075,942 shares; plus

(ii)    the number of shares of Common Stock which were available for additional award grant purposes under the Company’s 2001 Long-Term Incentive Stock Plan (the “2001 Plan”) immediately prior to the expiration of the authority to grant new awards under the 2001 Plan; plus

(iii)    the number of any shares of Common Stock which are subject to stock options granted under the 2001 Plan and are outstanding at the Effective Time which expire, or for

any reason are cancelled or terminated, after the Effective Time without being exercised; plus

(iv)    the number of any shares of Common Stock which are subject to restricted stock, restricted stock right, restricted performance stock right or other awards (other than stock options) granted under the 2001 Plan and are outstanding and unvested at the Effective Time that are subsequently forfeited, terminated, cancelled or otherwise reacquired by the Company without having become vested or paid (including, for purposes of clarity, any shares initially reserved but, at the conclusion of any applicable performance period ending after the Effective Time, not otherwise deliverable with respect to restricted performance stock right awards because actual performance for the performance period did not result in the maximum potential payout of the awards) (such awards, the “Outstanding Restricted Stock Awards”).

(a)    Upon (or, as may be necessary to effect the adjustment, immediately prior to): any reclassification, recapitalization, stock split (including a stock split in the form of a stock dividend) or reverse stock split; any merger, combination, consolidation, or other reorganization; any spin-off, split-up, or similar extraordinary dividend distribution in respect of the Common Stock; or any

exchange of shares of Common Stock or other securities of the Company, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; then the Committee shall equitably and proportionately adjust (1) the number and type of shares of Common Stock (or other securities) that thereafter may be made the subject of awards (including the specific share limits, maximums and numbers of shares set forth elsewhere in this Plan), (2) the number, amount and type of shares of Common Stock (or other securities or property) subject to any outstanding awards, (3) the grant, purchase, or exercise price (which term includes the base price of any SAR or similar right) of any outstanding awards, and/or (4) the securities, cash or other property deliverable upon exercise or payment of any outstanding awards, in each case to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding awards.

Unless otherwise expressly provided in the applicable award agreement, upon (or, as may be necessary to effect the adjustment, immediately prior to) any event or transaction described in the preceding paragraph or a sale of all or substantially all of the business or assets of the Company as an entirety, the Committee shall equitably and proportionately adjust the performance standards applicable to any then-outstanding performance-based awards to the extent necessary to preserve (but not increase) the level of incentives intended by the Plan and the then-outstanding performance-based awards.

It is intended that, if possible, any adjustments contemplated by the preceding two paragraphs be made in a manner that satisfies applicable legal, tax (including, without limitation and as applicable in the circumstances, Section 424 of the Code, Section 409A of the Code and Section 162(m) of the Code) and accounting (so as to not trigger any charge to earnings with respect to such adjustment) requirements.

(b)    Notwithstanding anything to the contrary in Section 6(a), the provisions of this Section 6(b) shall apply to an outstanding Plan award if a Change in Control (as defined in Section 6(e)) occurs. If the Company undergoes a Change in Control triggered by clause (iii) or (iv) of the definition thereof and the Company is not the surviving entity and the successor to the Company (if any) (or a parent thereof) does not agree in writing prior to the occurrence of the Change in Control to continue and assume the award following the Change in Control, or if for any other reason the award would not continue after the Change in Control, then upon the Change in Control: (i) if the award is a stock option, it shall vest fully and completely, any and all restrictions on exercisability or otherwise shall lapse, and it shall be fully exercisable; (ii) if the award is a SAR, it shall vest fully and completely, any and all restrictions on such SAR shall lapse, and it shall be fully exercisable; and (iii) if such award is an award or grant under Section 8(c) of the Plan, it shall immediately vest fully and completely, and all restrictions shall lapse, provided, however, that if the award is performance-based, the earnout or payout of the award, as applicable, shall be computed based on the performance terms of the award and based on actual performance achieved to the date of the Change in Control. No acceleration of vesting, exercisability and/or payment of an outstanding Plan award shall occur in connection with a Change in Control if either (i) the Company is the surviving entity, or (ii) the successor to the Company (if any) (or a parent thereof) agrees in writing prior to the Change in Control to assume the award; provided, however, that individual awards may provide for acceleration under these circumstances as contemplated by Section 6(c) below. If a stock option or other award is fully vested or becomes fully vested as provided in this paragraph

but is not exercised or paid prior to a Change in Control triggered by clause (iii) or (iv) of the definition thereof and the Company is not the surviving entity and the successor to the Company (if any) (or a parent thereof) does not agree in writing prior to the occurrence of the Change in Control to continue and assume the award following the Change in Control, or if for any other reason the award would not continue after the Change in Control, then the Committee may provide for the settlement in cash of the award (such settlement to be calculated as though the award was paid or exercised simultaneously with the Change in Control and based upon the then Fair Market Value of a share of Common Stock and subject, in the case of a performance-based award, to the Change in Control payment provisions set forth above). An option or other award so settled by the Committee shall automatically terminate. If, in such circumstances, the Committee does not provide for the cash settlement of an option or other award, then upon the Change in Control such option or award shall terminate, subject to any provision that has been made by the Committee through a plan of reorganization or otherwise for the survival, substitution or exchange of such option or right and further subject to any Change in Control settlement or payment provisions included in the applicable award agreement; provided that the option or award holder shall be given reasonable notice of such intended termination and an opportunity to exercise the option or award (to the extent an award other than an option must be exercised in order for the participant to realize the intended benefits) prior to or upon the Change in Control.

(c)    Notwithstanding the provisions of Section 6(b), awards issued under the Plan may contain specific provisions regarding the consequences of a Change in Control and, if contained in an award, those provisions shall be controlling in the event of any inconsistency. (For example, and without limitation, an award may provide that (i) acceleration of vesting will occur automatically upon a Change in Control, or (ii) acceleration will occur in connection with a Change in Control if the participant is terminated by the Company without cause or the participant terminates employment for good reason.) Furthermore, and notwithstanding the provisions of Section 6(b), a Change in Control shall not accelerate the payment of any award that is subject to Section 409A of the Code to the extent such acceleration would result in any tax, penalty or interest under Section 409A of the Code; provided that the Committee retains the authority contemplated by this Section 6 to the extent any modification of an award may be made in a manner which complies with (and does not result in any tax under) Section 409A of the Code or is otherwise exempt from Section 409A of the Code. The occurrence of a particular Change in Control under the Plan shall have no effect on any award granted under the Plan after the date of that Change in Control.

(d)    The Committee may make adjustments pursuant to Section 6(a) and/or deem an acceleration of vesting of awards pursuant to Section 6(b) to occur sufficiently prior to an event if necessary or deemed appropriate to permit the participant to realize the benefits intended to be conveyed with respect to the shares underlying the award; provided, however, that, the Committee will, in such circumstances, reinstate the original terms of an award if the related event does not actually occur.

(e)    A “Change in Control” of the Company shall be deemed to have occurred as of the first day that any one or more of the following conditions shall have been satisfied:

(i)    Any Person (other than those Persons in control of the Company as of the Effective Time, or other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any affiliate of the Company or a successor) becomes the Beneficial Owner, directly or indirectly, of securities of the Company representing twenty-five percent (25%) or more of either (1) the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (2) the combined voting power of the then-outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this clause (i): (A) “Person” or “group” shall not include underwriters acquiring newly-issued voting securities (or securities convertible into voting securities) directly from the Company with a view towards distribution, (B) creditors of the Company who become shareholders of the Company in connection with any bankruptcy of the Company under the laws of the United States shall not, by virtue of such bankruptcy, be deemed a “group” or a single Person for the purposes of this clause (i) (provided that any one of such creditors may trigger a Change in Control pursuant to this clause (i) if such creditor’s ownership of Company securities equals or exceeds the foregoing threshold), and (C) an acquisition shall not constitute a Change in Control if made by an entity pursuant to a transaction that is covered by and does not otherwise constitute a Change in Control under clause (iii) below;

(ii)    On any day after the Effective Time (the “Measurement Date”) Continuing Directors cease for any reason to constitute either: (1) if the Company does not have a Parent, a majority of the Board; or (2) if the Company has a Parent, a majority of the Board of Directors of the Controlling Parent. A director is a “Continuing Director” if he or she either:

A member of the Board (or Board of Directors of the Controlling Parent, as applicable) who was not a director on the applicable Initial Date shall be deemed to be an Initial Director for purposes of clause (2) above if his or her election, or nomination for election by the Company’s or the Controlling Parent’s shareholders, was approved by a vote of at least two-thirds (2/3) of the Initial Directors (including directors elected after the applicable Initial Date who are deemed to be Initial Directors by application of this provision) then in office. “Initial Date” means the later of (1) the Effective Time or (2) the date that is two (2) years before the Measurement Date.

(iii)    Consummation of a reorganization, merger, statutory share exchange or consolidation or similar corporate transaction involving the Company or any of its subsidiaries, a sale or other disposition of all or substantially all of the assets of the Company, or the acquisition of assets or stock of another entity by the Company or any of its subsidiaries (each, a “Business Combination”), in each case unless, following such Business Combination, (1) all or substantially all of the individuals and entities that were the Beneficial Owners of the Outstanding Company Common Stock and the Outstanding Company Voting Securities immediately prior to such Business Combination Beneficially Own, directly or indirectly, more than sixty percent (60%) of the then-outstanding shares of common stock and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the entity resulting from such Business Combination (including, without limitation, an entity that, as a result of such transaction, is a Parent of the Company or the successor of the Company) in substantially the same proportions as their ownership immediately prior to such Business Combination of the Outstanding Company Common Stock and the Outstanding Company Voting Securities, as the case may be, (2) no Person (excluding any entity resulting from such Business Combination or a Parent of the Company or any successor of the Company or any employee benefit plan (or related trust) of the Company or such entity resulting from such Business Combination or a Parent of the Company or the successor entity) Beneficially Owns, directly or indirectly, twenty-five percent (25%) or more of, respectively, the then-outstanding shares of common stock of the entity resulting from such Business Combination or the combined voting power of the then-outstanding voting securities of such entity, except to the extent that the ownership in excess of twenty-five percent (25%) existed prior to the Business Combination, and (3) a Change in Control is not triggered pursuant to clause (ii) above with respect to the Company (including any successor entity) or any Parent of the Company (or the successor entity).

(iv)    A complete liquidation or dissolution of the Company other than in the context of a transaction that does not constitute a Change in Control of the Company under clause (iii) above.

Notwithstanding the foregoing, in no event shall a transaction or other event that occurred prior to the Effective Time constitute a Change in Control. Notwithstanding anything in clause (iii) above to the contrary, a change in ownership of the Company resulting from creditors of the Company becoming shareholders of the Company in connection with any bankruptcy of the Company under the laws of the United States shall not trigger a Change in Control pursuant to clause (iii) above.

“Beneficial Owner” shall have the meaning ascribed to such term in Rule 13d-3 of the General Rules and Regulations under the 1934 Act. “Controlling Parent” means the Company’s Parent so long as a majority of the voting stock or voting power of that Parent is not Beneficially Owned, directly or indirectly through one or more subsidiaries, by any other Person. In the event that the Company has more than one “Parent,” then “Controlling Parent” means the Parent of the Company the majority of the voting stock or voting power of which is not Beneficially Owned, directly or indirectly through one or more subsidiaries, by any other Person. “Parent” means an entity that Beneficially Owns a majority of the voting stock or voting power of the Company, or

all or substantially all of the Company’s assets, directly or indirectly through one or more subsidiaries. “Person” shall have the meaning ascribed to such term in Section 3(a)(9) of the 1934 Act and used in Sections 13(d) and 14(d) thereof, including a “group” as defined in Section 13(d) thereof.

“Fair Market Value” for all purposes under the Plan shall mean the closing price of a share of Common Stock as reported by the New York Stock Exchange (the “Exchange”) for the date in question. If no sales of Common Stock were made on the Exchange on that date, the closing price of a share of Common Stock as reported by the Exchange for the next preceding day on which sales of Common Stock were made on the Exchange shall be substituted.

The Committee shall determine the type or types of award(s) to be made to each participant. Awards may be granted singly, in combination or in tandem. Awards also may be made in combination or in tandem with, in replacement of, as alternatives to, or as the payment form for grants or rights under any other employee or compensation plan of the Company, including the plan of any acquired entity. The types of awards that may be granted under the Plan are (subject, in each case, to the no repricing provisions of Section 3(b)):

(a)    Stock Options—A grant of a right to purchase a specified number of shares of Common Stock during a specified period as determined by the Committee. The purchase price per share for each option shall be not less than 100% of Fair Market Value on the date of grant. A stock option may be in the form of an ISO which, in addition to being subject to applicable terms, conditions and limitations established by the Committee, complies with Section 422 of the Code. If an ISO is granted, the aggregate Fair Market Value (determined on the date the option is granted) of Common Stock subject to an ISO granted to a participant by the Committee which first becomes exercisable in any calendar year shall not exceed $100,000.00 (otherwise, the intended ISO, to the extent of such excess, shall be rendered a nonqualified stock option). ISOs may only be granted to employees of the Company or a Subsidiary. (“Subsidiary” means a “subsidiary corporation” of the Company within the meaning of Section 424(f) of the Code.) The maximum term of each option (ISO or nonqualified) shall be ten (10) years. The price at which shares of Common Stock may be purchased under a stock option shall be paid in full at the time of the exercise in cash or such other method permitted by the Committee, including (i) tendering (either actually or by attestation) Common Stock; (ii) surrendering a stock award valued at Fair Market Value on the date of surrender; (iii) authorizing a third party to sell the shares (or a sufficient portion thereof) acquired upon exercise of a stock option and assigning the delivery to the Company of a sufficient amount of the sale proceeds to pay for all the shares acquired through such exercise; (iv) the Company withholding a number of shares of Common Stock otherwise deliverable pursuant to the award with a value sufficient to cover such exercise price; or (v) any combination of the above.

(b)    SARs—A right to receive a payment, in cash and/or Common Stock, equal to the excess of the Fair Market Value of a specified number of shares of Common Stock on the date the SAR is exercised over the “base price” of the award, which base price shall be set forth in the

applicable award agreement and shall not be less than 100% of the Fair Market Value of a share of Common Stock on the date of grant of the SAR. The maximum term of a SAR shall be ten (10) years.

(c)    Other Awards—Other awards, granted or denominated in Common Stock or units of Common Stock, may be granted under the Plan. Awards not granted or denominated in Common Stock or units of Common Stock (cash awards) also may be granted consistent with clause (ii) below.

(i)    All or part of any stock award may be subject to conditions and restrictions established by the Committee, and set forth in the award agreement, which may include, but are not limited to, continuous service with the Company (or a subsidiary or affiliate), achievement of specific business objectives, and other measurements of individual, business unit or Company performance. Awards may be granted under this Section 8(c) to any individual eligible pursuant to Section 4; provided, however, that unless the Committee otherwise provides, awards under this Section 8(c) to employees of the Company or a Subsidiary that are either granted or become vested, exercisable or payable based on attainment of one or more of the performance goals related to the business criteria identified below, shall be deemed to be intended as Section 162(m) Awards under Section 8(c)(ii).

(ii)    Without limiting the generality of the foregoing, and in addition to stock options and SAR grants, other performance-based awards within the meaning of Section 162(m) of the Code (“Section 162(m) Awards”) may be granted under the Plan, whether in the form of restricted stock, performance stock, phantom stock or other rights, the vesting of which depends on the performance of the Company relative to pre-established goals on a consolidated, segment, sector, subsidiary, division, or plant basis with reference to:

The financial metrics identified above can be measured on an as reported or pension adjusted basis, on an annual or cumulatively over a defined period of time basis, and can be measured on an absolute, relative or growth basis. The applicable business criteria and the specific performance goals for Section 162(m) Awards must be approved by the Committee in advance of applicable deadlines under the Code and while the performance relating to such goals remains substantially uncertain. The applicable performance period may range from three months to ten years. Performance targets shall, to the extent determined by the Committee to be equitable and appropriate and unless otherwise expressly provided in the applicable award agreement, be adjusted to mitigate the impact of material, unusual or nonrecurring gains and losses, changes in law, regulations or in generally accepted accounting principles, accounting charges or other extraordinary events not foreseen at the time the targets were set. In no event shall share-based Section 162(m) Awards granted to any eligible person under this Plan exceed the limit set forth in Section 5(e). In no event shall grants to any eligible person under this Plan of Section 162(m) Awards payable only in cash in any calendar year and not related to shares provide for payment of more than $10,000,000. Except as otherwise permitted under Section 162(m) of the Code, before any Performance-Based Award is paid, the Committee must approve (by resolution or other valid action of the Committee) that the performance goal and any other material terms of the Performance-Based Award were in fact satisfied. The Committee shall have discretion to determine the conditions, restrictions or other limitations, in accordance with the terms of the Plan and Section 162(m) of the Code, on the payment of individual Section 162(m) Awards. The Committee reserves the right to reduce the amount payable with respect to any Performance-Based Award in accordance with any standards the Committee may impose or on any other basis (including the Committee’s discretion) as the Committee may determine appropriate. Section 162(m) Awards may be granted only to employees of the Company or a Subsidiary. The Plan, and this Section 8(c)(ii) in particular, does not limit the Company’s authority to grant awards intended as performance-based compensation within the meaning of Section 162(m) of the Code under any other compensation plan that may be maintained by the Company or any of its Subsidiaries from time to time.

The Committee may provide that any awards under the Plan earn dividends or dividend equivalents; provided, however, that dividend equivalent rights may not be granted in connection with any option or SAR granted hereunder. Such dividends or dividend equivalents may be paid currently or may be credited to a participant’s account, provided that as to any dividend equivalent

rights granted in connection with an award granted under the Plan that is subject to performance-based vesting requirements, no payment shall be made with respect to such dividend equivalent right (or, in the case of a restricted stock or similar award where the dividend must be paid as a matter of law, the dividend payment shall be subject to forfeiture or repayment, as the case may be) unless the related performance-based vesting conditions of such award are satisfied. Any crediting of dividends or dividend equivalents may be subject to such restrictions and conditions as the Committee may establish, including reinvestment in additional shares or share equivalents.

Payment of awards may be in the form of cash, Common Stock, other awards or combinations thereof as the Committee shall determine, and with such restrictions as it may impose. The Committee may also require or permit participants to elect to defer the issuance of shares or the settlement of awards in cash under such rules and procedures as it may establish under the Plan. It may also provide that deferred settlements include the payment or crediting of interest on the deferral amounts, or the payment or crediting of dividend equivalents where the deferral amounts are denominated in shares.

Unless otherwise expressly provided in (or pursuant to) this Section 11, by applicable law or by the award agreement, (i) all awards are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge; (ii) awards shall be exercised only by the holder; and (iii) amounts payable or shares issuable pursuant to an award shall be delivered only to (or for the account of) the holder. The foregoing exercise and transfer restrictions shall not apply to: (a) transfers to the Company; (b) the designation of a beneficiary to receive benefits in the event of the participant’s death or, if the participant has died, transfers to or exercise by the participant’s beneficiary, or, in the absence of a validly designated beneficiary, transfers by will or the laws of descent and distribution; (c) transfers pursuant to a qualified domestic relations order (as defined in the Code) (in the case of ISOs, to the extent such transfers are permitted by the Code); (d) if the participant has suffered a disability, permitted transfers to or exercises on behalf of the holder by his or her legal representative; or (e) the authorization by the Committee of “cashless exercise” procedures. The Committee by express provision in the award or an amendment thereto may permit an award (other than an ISO) to be transferred to, exercised by and paid to certain persons or entities related to the participant, including but not limited to members of the participant’s family, charitable institutions, or trusts or other entities whose beneficiaries or beneficial owners are members of the participant’s family and/or charitable institutions, or to such other persons or entities as may be expressly approved by the Committee, pursuant to such conditions and procedures as the Committee may establish. Any permitted transfer shall be subject to the condition that the Committee receive evidence satisfactory to it that the transfer is being made for estate and/or tax planning purposes (or to a “blind trust” in connection with the participant’s termination of employment or service with the Company (or a subsidiary or affiliate) to assume a position with a governmental, charitable, educational or similar non‑profit institution) and on a basis consistent with the Company’s lawful issue of securities.

Awards under the Plan shall be evidenced by agreements that set forth the terms, conditions and limitations for each award which may include the term of an award, the provisions applicable in the event the participant’s employment or service terminates, and the Company’s authority to unilaterally or bilaterally amend, modify, suspend, cancel or rescind any award; provided, however, that such authority shall be subject to the no repricing provisions of Section 3(b) hereof. The Committee need not require the execution of any such agreement, in which case acceptance of the award by the respective participant shall constitute agreement to the terms of the award.

The Plan may only be amended by a majority of the Board of Directors as it deems necessary or appropriate to better achieve the purpose of the Plan, except that no such amendment shall be made without the approval of the Company’s shareholders if the amendment would increase the number of shares available for issuance under the Plan (except for increases or adjustments expressly contemplated by Sections 5 and 6) or shareholder approval is otherwise required under applicable law or applicable New York Stock Exchange listing requirements.

The Company shall have the right to deduct from any settlement of an award made under the Plan, including the delivery or vesting of shares, or deduct from any other compensation otherwise payable to the award holder a sufficient amount to cover withholding of any Federal, state or local taxes required by law with respect to such award settlement or to take such other action as may be necessary to satisfy any such withholding obligations. The Committee may permit shares to be used to satisfy required tax withholding and such shares shall be valued at the Fair Market Value as of the settlement date of the applicable award.

Unless otherwise specifically determined by the Committee, settlements of awards received by participants under the Plan shall not be deemed a part of a participant’s regular, recurring compensation for purposes of calculating payments or benefits from any benefit plan or severance program of the Company (or a subsidiary or affiliate), or any severance pay law of any country. Further, the Company may adopt other compensation programs, plans or arrangements as it deems appropriate or necessary.

Unless otherwise determined by the Committee, the Plan shall be unfunded and shall not create (or be construed to create) a trust or a separate fund or funds. The Plan shall not establish any fiduciary relationship between the Company and any participant or other person. To the extent any person holds any rights by virtue of a grant awarded under the Plan, such rights (unless otherwise determined by the Committee) shall be no greater than the rights of an unsecured general creditor of the Company.

No person shall have any claim or rights to be granted an award under the Plan, and no participant shall have any rights under the Plan to be retained in the employ or service of the Company (or any subsidiary or affiliate).

The validity, construction and effect of the Plan, any award agreements or other documents setting forth the terms of an award, and any actions taken or relating to the Plan shall be determined in accordance with the laws of the State of Delaware and applicable Federal law. If any provision of the Plan, any award agreement, or any other document setting forth the terms of an award shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of the Plan or such other document shall continue in effect.

The Plan, the granting and vesting of awards under the Plan and the issuance and delivery of Common Stock and/or the payment of money under the Plan or under awards granted hereunder are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal securities and banking laws) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Company, be necessary or advisable in connection therewith. Any securities delivered under the Plan shall be subject to such restrictions as the Company may deem necessary or desirable to assure compliance with all applicable legal requirements.

The Plan and the awards granted under the Plan are intended to comply with (or be exempt from, as the case may be) Section 409A of the Code so as to avoid any tax, penalty or interest under Section 409A of the Code. The Plan shall be construed, operated and administered consistent with this intent.

The Plan shall be binding on all successors and assigns of a participant, including, without limitation, the estate of such participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the participant’s creditors.

Except as otherwise provided in the award agreement, a participant shall have no rights as a shareholder until he or she becomes the holder of record of shares of Common Stock.

Awards under the Plan are subject to recoupment pursuant to the Company’s Policy Regarding the Recoupment of Certain Performance-Based Compensation Payments as in effect from time to time, and participants shall promptly make any reimbursement requested by the Board or Committee pursuant to such policy with respect to any award.
