AMENDED AND RESTATED 2010 STOCK PLAN

Amended and Restated as of February 20, 2012

I. GENERAL PROVISIONS

A. PURPOSE OF THE PLAN

This 2010 Stock Plan (the “Plan”) is intended to promote the interests of KRATOS DEFENSE & SECURITY SOLUTIONS, INC., a Delaware corporation (“Corporation”), by providing Eligible Persons (as defined in Section I(D) below) with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Corporation as an incentive for them to continue in such employ or service.

Unless otherwise defined herein, all capitalized terms shall have the meaning assigned to them in the attached Appendix.

B. STRUCTURE OF THE PLAN

The Plan shall be divided into two (2) separate equity programs:

(i) the Option Grant Program under which Eligible Persons may, at the discretion of the Board, be granted options to purchase Shares of Common Stock, thereby becoming Optionees.

(ii) the Stock Issuance and Restricted Stock Unit Program under which Eligible Persons may, at the discretion of the Board, be issued shares of common stock directly, through the immediate purchase of such shares, as a bonus for services rendered to the Corporation (or any Parent or Subsidiary), or the grant and vesting of Restricted Stock Units (RSUs), thereby becoming Participants.

The provisions of Articles One and Four shall apply to both equity programs under the Plan and shall accordingly govern the interests of all persons under the Plan.

C. ADMINISTRATION OF THE PLAN

The Plan shall be administered by the Corporation’s Board of Directors (“Board”), or in the discretion of the Board, a committee consisting of no less than two Non-Employee Directors or persons meeting such other requirements as may be imposed by Rule 16(b) under the 1934 Act (“Committee”).

The Board or Committee shall have full power and authority (subject to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of the Plan and to make such determinations under, and issue such interpretations of, the Plan and any outstanding options or stock issuances thereunder as it may deem necessary or advisable. Decisions of the Board shall be final and binding on all parties who have an interest in the Plan or any option or stock issuance thereunder.

D. ELIGIBILITY

The persons eligible to participate in the Plan (“Eligible Persons”) are:

1. Officers, directors, employees and consultants; and

2. Consultants and other independent advisors who provide services to the Corporation, or any parent or subsidiary of the Corporation.

Awards or Grants may be granted after March 30, 2011 to individuals who were not employed by the Corporation, or its subsidiaries, on March 30, 2011. Notwithstanding the foregoing, individuals who were employed by Herley Industries, Inc. on March 30, 2011 may also be granted Awards or Grants under the Plan.

Notwithstanding the foregoing, the following limitations shall apply:

1. Incentive Options may only be granted to Employees other than the Chairman, Chief Executive Officer and directors.

2. Nothing in this Plan, as amended extends the time during which Shares of Common Stock are available for Awards or Grants beyond the period when they would have been available under the Plan as it existed on the date prior to March 30, 2011.

3. To the extent required by NASDAQ Listing Rule 5635 and IM-5635-1, Awards or Grants after March 30, 2011 may not be granted to individuals who were employed by or providing services to the Corporation, or its subsidiaries, on March 30, 2011.

The Board or Committee shall have full authority to determine, (i) with respect to the grants made under the Option Grant Program, described in Article Two below, which Eligible Persons are to receive the option grants, the time or times when those grants are to be made, the number of shares to be covered by each such grant, the status of the granted option as either an Incentive Option or a Non-Qualified Option, the time or times when each option is to become exercisable, the vesting schedule (if any) applicable to the option shares and the maximum term for which the option is to remain outstanding, and (ii) with respect to stock issuances or RSU Awards made under the Stock Issuance and Restricted Stock Unit Program, described in Article Three, which Eligible Persons are to receive such stock issuances or RSU Awards, the time or times when those issuances or RSU Awards are to be made, the number of shares or RSU Awards to be issued to each Participant, the vesting schedule (if any) applicable to the issued shares or awarded RSUs and the consideration to be paid by the Participant for such shares or RSUs.

The Board or Committee shall have the absolute discretion either to grant options in accordance with the Option Grant Program, to issue stock in accordance with the Stock Issuance Program, or to award RSUs in accordance with the Restricted Stock Unit Program.

E. STOCK SUBJECT TO THE PLAN

The stock issuable under the Plan shall be shares of the Corporation’s authorized but unissued or reacquired common stock. Notwithstanding the foregoing, no more than 503,704 shares of Common Stock may be issued under the Plan after March 30, 2011, adjusted as described below.

Shares of common stock subject to outstanding options shall be available for subsequent issuance under the Plan to the extent (i) the options expire or terminate for any reason prior to exercise in full, or (ii) the options are cancelled in accordance with the cancellation-regrant provisions of Article Two. Unvested shares issued under the Plan and subsequently repurchased by the Corporation, at the option exercise or direct issue price paid per share, pursuant to the Corporation’s repurchase rights under the Plan shall be added back to the number of shares of common stock reserved for issuance under the Plan. Shares of common stock subject to outstanding RSU Awards shall be available for subsequent issuance under the Plan to the extent that the shares are subject to Awards that (i) have been terminated, expired unexercised, forfeited or settled in cash; (ii) have been retained by the Corporation in payment or satisfaction of the exercise price, purchase price or tax withholding obligation of an Award; or (iii) otherwise do not result in the issuance of Shares of Common Stock in connection with payment or settlement of an award.

If there is any change to the common stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding common stock as a class without the Corporation’s receipt of consideration, then appropriate adjustments shall be made to (i) the maximum number and/or class of securities issuable under the Plan, and (ii) the number and/or class of securities and the exercise price per share in effect under each outstanding option or Award in order to prevent the dilution or enlargement of benefits thereunder.

Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Board or Committee and set forth in the documents evidencing the option grant. However, no option shall have a term in excess of five (5) years measured from the option grant date.

3. Effect of Termination of Service.

a. The following provisions shall govern the exercise of any vested option held by the Optionee at the time of cessation of Optionee’s employment or rendering of services to the Corporation (collectively “Service”) or death:

(i) Should the Optionee cease to remain in Service for any reason other than death, Disability or Misconduct, then the Optionee shall have a period of three (3) months following the date of such cessation of Service during which to exercise each option held by such Optionee to the extent exercisable on the date of such termination.

(ii) Should Optionee’s Service terminate by reason of Disability, then the Optionee shall have a period of twelve (12) months following the date of such cessation of Service during which to exercise each outstanding option held by such Optionee to the extent exercisable on the date of such termination.

(iv) Under no circumstances, however, shall any such option be exercisable after the specified expiration of the option term.

(v) All vested options shall terminate upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term.

b. The Board or Committee shall have the discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to:

(i) extend the period of time for which the option is to remain exercisable following Optionee’s cessation of Service or death from the limited period otherwise in effect for that option to such greater period of time as it shall deem appropriate, but in no event beyond the expiration of the option term, and/or

(ii) permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested shares of common stock for which such option is exercisable at the time of the Optionee’s cessation of Service

but also with respect to one or more additional installments in which the Optionee would have vested under the option had the Optionee continued in Service.

4. Stockholder Rights. The holder of an option shall have no stockholder rights with respect to the shares subject to the option until such person exercises the option, pays the exercise price and becomes the recordholder of the purchased shares.

5. Limited Transferability of Options. During the lifetime of the Optionee, the option shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or, following the Optionee’s death, by the laws of descent and distribution.

B. CORPORATE TRANSACTION

1. All unvested options shall automatically vest in full if and when either of the following stockholder approved transactions to which the Corporation is a party are consummated: (i) a merger or consolidation in which securities possessing more than fifty percent (50%) of the total combined voting power of the Corporation’s outstanding securities are transferred to a person or persons different from the persons holding those securities immediately prior to such transaction, or (ii) the sale, transfer or other disposition of all or substantially all of the Corporation’s assets in complete liquidation or dissolution of the Corporation. However, the shares subject to an outstanding option shall not vest on such an accelerated basis if and to the extent: (i) such option is assumed by the successor corporation (or parent thereof) in the Corporate Transaction or (ii) such option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested option shares at the time of the Corporate Transaction and provides for subsequent payout in accordance with the same vesting schedule applicable to those unvested option shares or (iii) the acceleration of such option is subject to other limitations imposed by the Board or Committee at the time of the option grant.

2. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Corporate Transaction, had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments shall also be made to (i) the number and class of securities available for issuance under the Plan following the consummation of such Corporate Transaction and (ii) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same.

3. The Board or Committee shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains outstanding, to structure one or more options so that those options shall automatically accelerate and vest in full (and any repurchase rights of the Corporation with respect to the unvested shares subject to those options shall immediately terminate) upon the occurrence of a Corporate Transaction, whether or not those options are to be assumed in the Corporate Transaction.

4. The Board or Committee shall also have full power and authority, exercisable either at the time the option is granted or at any time while the option remains outstanding, to structure such option so that the shares subject to that option will automatically vest on basis should the Optionee’s Service terminate by reason of the Optionee’s involuntary dismissal or discharge by the Corporation for reasons other than misconduct (“Involuntary Termination”) within a designated period (not to exceed one year) following the effective date of any Corporate Transaction in which the option is assumed and the repurchase rights applicable to those shares do not otherwise terminate. Any option so accelerated shall remain exercisable for the fully-vested option shares until the expiration or sooner termination of the option term.

5. The portion of any Incentive Option accelerated in connection with a Corporate Transaction shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar ($100,000.00) limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws.

6. The grant of options under the Plan shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

III. STOCK ISSUANCE PROGRAM

A. STOCK ISSUANCE TERMS

Shares of common stock may be issued at the discretion of the Board or Committee under the Stock Issuance Program through direct and immediate issuances without any intervening option grants. Each such stock issuance shall comply with the terms specified below.

1. Issuances.

Shares of common stock may be issued under the Stock Issuance Program for past or future services rendered, or to be rendered, to the Corporation (or any Parent or Subsidiary) as the Board may deem appropriate in each individual instance.

2. Vesting Provisions.

a. Shares of common stock issued under the Stock Issuance Program shall vest at the discretion of the Board or Committee.

b. The Participant shall have full stockholder rights with respect to any shares of common stock issued to the Participant under the Stock Issuance

Program. Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares.

B. RESTRICTED STOCK UNIT AWARDS (RSU Awards)

1. Grant.

The Board may grant Restricted Stock Unit Awards (RSU Awards) to Eligible Persons, in all cases pursuant to Award Agreements setting forth terms and conditions that are not inconsistent with the Plan. The Board shall establish as to each RSU Award the number of Shares deliverable or subject to the Award (which number may be determined by a written formula), and the period or periods of time (the “Restriction Period”) at the end of which all or some restrictions specified in the Award Agreement shall lapse, and the Participant shall receive Unrestricted Shares (or cash to the extent provided in the Award Agreement) in settlement of the Award. Such restrictions may include, without limitation, restrictions concerning voting rights and transferability, and such restrictions may lapse separately or in combination at such times and pursuant to such circumstances or based on such criteria as selected by the Board, including, without limitation, criteria based on the Participant’s duration of employment, directorship or consultancy with the Corporation, individual, group, or divisional performance criteria, corporation performance, or other criteria selection by the Board. The Board may make RSU Awards with or without the requirement for payment of cash or other consideration. In addition, the Board may grant Awards hereunder in the form of Unrestricted Shares which shall vest in full upon the Grant Date or such other date as the Board may determine or which the Board may issue pursuant to any program under which one or more Eligible Persons (selected by the Board in its sole discretion) elect to pay for such Shares or to receive Unrestricted Shares in lieu of cash bonuses that would otherwise be paid.

2. Vesting and Forfeiture.

The Board shall set forth, in an Award Agreement granting RSUs, the terms and conditions under which the Participant’s interest in the Shares subject to RSUs will become vested and non-forfeitable. Except as set forth in the applicable Award Agreement or as the Board otherwise determines, upon termination of a Participant’s Continuous Service for any reason, the Participant shall forfeit his or her RSUs to the extent the Participant’s interest therein has not vested on or before such termination date; provided that if a Participant purchases Restricted Shares and forfeits them for any reason, the Corporation shall return the purchase price to the Participant to the extent either set forth in an Award Agreement or required by Applicable Laws.

3. Certificates for Restricted Shares.

Unless otherwise provided in an Award Agreement, the Corporation shall hold certificates representing Restricted Shares and dividends (whether in Shares or cash) that accrue with respect to them until the restrictions lapse, and the Participant shall provide the Corporation with appropriate stock powers endorsed in blank. The Participant’s failure to provide such stock

powers within ten days after a written request from the Corporation shall entitle the Board to unilaterally declare a forfeiture of all or some of the Participant’s Restricted Shares.

4. Issuance of Shares upon Vesting.

As soon as practicable after vesting of a Participant’s right to receive Shares underlying RSUs, the Corporation shall deliver to the Participant, free from vesting restrictions, one Share free of the vesting restriction for each vested RSU, unless an Award Agreement provides otherwise and subject to Section IV(D) regarding withholding of taxes. No fractional Shares shall be distributed, and cash shall be paid in lieu thereof.

IV. MISCELLANEOUS

A. ADJUSTMENTS DUE TO STOCK SPLITS, MERGERS, CONSOLIDATION, ETC.

If, at any time, the Corporation shall take any action, whether by stock dividend, stock split, combination of shares or otherwise, which results in a proportionate increase or decrease in the number of shares of common stock theretofore issued and outstanding, the number of shares which are reserved for issuance under the Plan and the number of shares which, at such time, are subject to options, issuances or RSU Awards shall, to the extent deemed appropriate by the Board or Committee, be increased or decreased in the same proportion, provided, however, that the Corporation shall not be obligated to issue fractional shares.

Likewise, in the event of any change in the outstanding shares of common stock by reason of any recapitalization, merger, consolidation, reorganization, combination or exchange of shares or other corporate change, the Board or Committee shall make such substitution or adjustments, if any, as it deems to be appropriate, as to the number or kind of shares of common stock or other securities which are reserved for issuance under the Plan and the number of shares or other securities which, at such time are subject to Options, issuances or RSU Awards.

B. EFFECTIVE DATE AND TERM OF PLAN

1. The Plan shall become effective on March 23, 2010, provided that no Incentive Options may be granted unless the Plan is first approved by Herley’s stockholders. The Board may grant options, issue shares and grant awards under the Plan at any time after the effective date of the Plan and before the date fixed herein for termination of the Plan.

2. The Plan shall terminate upon the earliest of (i) the expiration of the ten (10)-year period measured from the date the Plan is adopted by the Board, (ii) the date on which all shares available for issuance under the Plan shall have been issued as vested shares or (iii) the termination of all outstanding options, issuances or RSU Awards in connection with a Corporate Transaction. All options, unvested stock issuances and unvested RSU Awards outstanding at the time of a clause (i) termination event shall continue to have full force and effect in accordance with the provisions of the documents evidencing those options, issuances or RSU Awards.

C. AMENDMENT OF THE PLAN

The Board or Committee shall have complete and exclusive power and authority to amend or modify the Plan in any or all respects, except for those persons ineligible to participate. However, no such amendment or modification shall adversely affect the rights and obligations with respect to options, unvested stock issuances or unvested RSU Awards at the time outstanding under the Plan unless the Optionee or the Participant consents to such amendment or modification. In addition, certain amendments may require stockholder approval pursuant to Applicable Laws.

D. WITHHOLDING

The Corporation’s obligation to deliver shares of common stock upon the exercise of any options, upon the issuance of shares issued under the Plan or upon the vesting of RSUs awarded under the Plan shall be subject to the satisfaction of all applicable Federal, state and local income and employment tax withholding requirements.

E. REGULATORY APPROVALS

The implementation of the Plan, the granting of any options under the Plan, the issuance of any shares of common stock (i) upon the exercise of any option or (ii) under the Stock Issuance and Restricted Stock Unit Program shall be subject to the Corporation’s obtaining all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the options granted under it, the shares of common stock issued pursuant to it, and the RSUs awarded under it.

F. NO EMPLOYMENT OR SERVICE RIGHTS

Nothing in the Plan shall confer upon the Optionee or the Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining such person) or of the Optionee or the Participant, which rights are hereby expressly reserved by each, to terminate such person’s Service at any time for any reason, with or without cause.

(b) Neither you nor any person claiming under or through you will have any of the rights or privileges of a stockholder of the Company with respect to any Shares deliverable hereunder unless and until certificates representing such Shares have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to you or your broker.

(c) Prior to actual distribution of Shares pursuant to any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3. Payment After Satisfaction of Vesting Restrictions. As soon as practicable after the Vesting Date, the Company will issue to you or your duly-authorized transferee, free from vesting restrictions (but subject to such legends as the Company determines to be appropriate), one Share for each vested RSU. Payment is subject to Section 8.

4. Forfeiture upon Termination of Continuous Service. If your Continuous Service terminates for any reason, any unvested RSUs awarded by this Award immediately will be forfeited without any payment to you. This Award shall be canceled and become automatically null and void immediately thereafter, but only to the extent your RSUs have not vested, pursuant to Section 1 above, on or before the date your Continuous Service ends. This Section 4 is subject to the terms of any employment agreement between you and the Company (and/or any Affiliate) in effect when your Continuous Service terminates.

5. Change in Control. In the event that a Change in Control occurs prior to the termination of the vesting schedule specified herein, RSUs vested as of the effective date of the Change in Control shall be settled by the Company through the issuance of Shares immediately prior to the effective date of the Change in Control.

6. Payments after Death. In the absence of a designation of beneficiary, any distribution or delivery to be made to you under this Award Agreement, if you are then deceased, will be made to the administrator or executor of your estate, who must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. RSUs not vested as of your death shall be forfeited at no cost to the Company.

7. Grant is Not Transferable. Your rights under this Award Agreement may not be sold, pledged, or otherwise transferred (whether by operation of law or otherwise) without the prior written consent of the Committee, except to the limited extent provided in Section 6. Further, your rights under this Award Agreement will not be subject to sale under execution,

attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this Award, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this Award and the rights and privileges conferred hereby immediately will become null and void.

8. Taxes.

(a) Code Section 409A. Notwithstanding anything to the contrary in this Award Agreement, if you are a “specified employee” (as determined in accordance with Code Section 409A and related Treasury guidance and related Treasury guidance and regulations) and a payment under this Award Agreement would be subject to additional taxes and interest under Section 409A of the Code, then any such payment that you would otherwise be entitled to receive during the first six months following the date of your “separation from service” (as determined in accordance with Section 409A of the Code and related Treasury guidance and regulations) from the Company shall be accumulated and paid on the date that is six (6) months and one (1) day following the date of your separation from service, or if earlier, upon your death.

(b) Except to the extent otherwise specifically provided in an employment or consulting agreement between you and the Company, by signing this Award Agreement, you acknowledge that you shall be solely responsible for the satisfaction of any applicable taxes that may arise pursuant to this Award (including taxes arising under Code Sections 409A (regarding deferred compensation) or 4999 (regarding golden parachute excise taxes)), and that neither the Company nor the Committee shall have any obligation whatsoever to pay such taxes or to otherwise indemnify or hold you harmless from any or all of such taxes.

(c) Notwithstanding any contrary provision of this Award Agreement, no certificate representing the Shares will be issued to you, unless and until you have made satisfactory arrangements (as determined by the Company) with respect to the payment of income, employment and other taxes which the Company determines must be withheld or otherwise remitted to the government with respect to such Shares.

(d) To the extent determined appropriate by the Company in its discretion, it shall have the right (but not the obligation) to satisfy any tax withholding obligations by reducing the number of Shares otherwise deliverable to you.

(e) If you fail to make satisfactory arrangements for the payment of any required tax withholding obligations hereunder at the time any applicable RSUs otherwise are scheduled to vest pursuant to this Award Agreement, you will forfeit permanently such RSUs and any right to receive Shares thereunder, and the RSUs will be returned to the Company at no cost to the Company.

(f) The Committee shall have the sole discretion to interpret the requirements of the Code, including Section 409A, for purposes of the Plan and this Award Agreement.

9. No Effect on Employment. By executing this Award Agreement, you acknowledge and agree that (i) your employment with the Company is on an at-will basis only; (ii) nothing in this Award Agreement or the Plan confers on you any right to continue an employment,

service or consulting relationship with the Company, nor shall it affect in any way your right or the Company’s right to terminate or change the terms of your employment, service, or consulting relationship at any time, with or without Cause; and (iii) the Company would not have granted this Award to you but for these acknowledgements and agreements.

10. Additional Conditions to Issuance of Stock. If at any time the Company determines, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to you (or your estate), such issuance will not occur unless and until such listing, registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

11. Investment Purposes. By executing this Award, you represent and warrant to the Company that any Shares issued to you pursuant to your RSUs will be for investment for your own account and not with a view to, for resale in connection with, or with an intent of participating directly or indirectly in, any distribution of such Shares within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

12. Securities Law Restrictions. Regardless of whether the offering and sale of Shares under the Plan have been registered under the Securities Act, or have been registered or qualified under the securities laws of any state, the Company at its discretion may impose restrictions upon the sale, pledge or other transfer of such Shares (including the placement of appropriate legends on stock certificates or the imposition of stop-transfer instructions) if, in the judgment of the Company, such restrictions are necessary or desirable in order to achieve compliance with the Securities Act or the securities laws of any state or any other law or to enforce the intent of this Award.
