 EXHIBIT 10.38 
 ALION SCIENCE AND TECHNOLOGY CORPORATION 
 PERFORMANCE SHARES AND
RETENTION PHANTOM STOCK PLAN 
 (Amended and Restated as of June 25, 2013) 

The Alion Science and Technology Corporation Performance Shares and Retention Phantom Stock Plan (the “Plan”) was
initially established by Alion Science and Technology Corporation, a Delaware corporation (“Alion” or the “Company”), effective as of January 24, 2005. The Plan is hereby amended and restated effective as of
June 25, 2013. 
 ARTICLE I  
 PURPOSE 
 The purpose of the Plan is to attract and retain key management
employees of the Company and to provide such persons with a proprietary interest in the Company and an incentive to increase shareholder value through the granting of phantom shares of common stock of the Company. 

ARTICLE II 

DEFINITIONS 
 For the purpose of the Plan, unless the context requires otherwise, the following terms shall have the meanings indicated: 
 2.1. “Administrative Committee” means the Compensation Committee of the Board, or such person or persons as the Compensation Committee shall designate, unless the Board resolves to act itself as
the Administrative Committee. 
 2.2. “Affiliate” means an entity which is a member of a “controlled group”
of corporations with Alion under Code Section 414(b) or a trade or business under common control with Alion under Code Section 414(c); provided, however, that in applying Code Sections 1563(a)(1), (2) or (3) and for the purposes
of Code Section 414(b), the language “at least 50 percent” will be used instead of “at least 80 percent” each place it appears, and in applying Treasury Regulation Section 1.414(c)-2 for purposes of Code
Section 414(c), the language “at least 50 percent” will be used instead of “at least 80 percent” each place it appears. In addition, to the extent the Administrative Committee determines that legitimate business criteria
exist to use a reduced ownership percentage to determine whether an entity is an Affiliate for purposes of determining whether a Termination of Employment has occurred, the Administrative Committee may designate an entity that would meet the
definition of “Affiliate” by substituting “20 percent” in place of “50 percent” in the preceding sentence as an Affiliate. Such designation shall be made by December 31, 2007 or, if later, at the time a 20 percent
or more ownership interest in such entity is acquired. 
 2.3. “Award” means a grant of the opportunity to receive
Performance Share Phantom Stock or Retention Phantom Stock under this Plan.

between the Company and a Participant with respect to an Award granted under the Plan shall incorporate the terms of this Plan and shall contain such terms and conditions, consistent with the provisions of the Plan, as may be established by the
Administrative Committee. Provisions in any Phantom Stock Agreement relating to matters such as non-competition, non-solicitation and protection of intellectual property are hereby deemed to be consistent with the Plan.

fide leave of absence (such as temporary employment by the government) if the period of such leave does not exceed six months or such longer period as the Participant’s right to reemployment with the Company or any Affiliate is provided
either by statute or by contract. If the period of leave exceeds six months and the Participant’s right to reemployment is not provided either by statute or by contract, the Termination of Employment will be deemed to occur on the first date
immediately following such six-month period. Whether a Participant incurs a termination of employment with the Company or an Affiliate will be determined in accordance with the requirements of Code Section 409A.

 3.1. General. The Plan shall be
administered by the Administrative Committee. The Administrative Committee shall have the full and final authority, in its discretion, to interpret conclusively the provisions of the Plan; to adopt such rules for carrying out the Plan as it may deem
advisable; to decide all questions of fact arising in the application of the Plan; and to make all other determinations necessary or advisable for the administration of the Plan. 

3.2. Procedure. The Administrative Committee shall meet at such times and places and upon such notice as it may
determine. A majority of the members of the Board or committee serving as Administrative Committee hereunder shall constitute a quorum. Any acts by the Administrative Committee may be taken at any meeting at which a quorum is present and shall be by

Committee. Members of the Board or Administrative Committee who are either eligible for Awards or have been granted Awards may vote on any matters affecting the administration of the Plan or the grant of Awards pursuant to the Plan, except that no
such member shall act upon the granting of an Award to himself or herself, but any such member may be counted in determining the existence of a quorum at any meeting of the Administrative Committee during which action is taken with respect to the
granting of an Award to him or her. 
 3.3. Duties. The Administrative Committee shall have full
power and authority to administer and interpret the Plan and to adopt such rules, regulations, agreements, guidelines and instruments for the administration of the Plan and for the conduct of its business as the Administrative Committee deems
necessary or advisable, all within the Administrative Committee’s sole and absolute discretion. The Administrative Committee shall have full power and authority to take all other actions necessary to carry out the purpose and intent of the
Plan, including, but not limited to, the authority to: 
 (a) construe the Plan and any Award under the
Plan; 
 (b) select the Employees to whom Awards may be granted and the time or times at which Awards shall be
granted; 
 (c) determine the number of shares of Common Stock to be covered by or used for reference purposes
for any Award; 
 (d) determine and modify from time to time the terms and conditions, including restrictions, of
any Award and to approve the form of Phantom Stock Agreements; 
 (e) impose limitations on Awards, including

 (f) modify, extend or renew outstanding Awards, or accept the surrender of
outstanding Awards and substitute new Awards subject to restrictions or limitations of the Code; or 
 (g)
prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws. 

3.4. Limited Liability. To the maximum extent permitted by law, no member of the Board or committee serving as
Administrative Committee hereunder shall be liable for any action taken or decision made in good faith relating to the Plan or any Award. 
 3.5. Effect of Administrative Committee’s Decision. All actions taken and decisions and determinations made by the Administrative Committee on all matters relating to the Plan
pursuant to the powers vested in it hereunder shall be in the Administrative Committee’s sole and absolute discretion and shall be conclusive and binding on all parties concerned, including the Company, its stockholders, any Participants in the
Plan and any other employee of the Company, and their respective successors in interest. 
 ARTICLE IV 

PARTICIPATION 
 Individual Participants in the Plan shall be selected by the Administrative Committee in its sole discretion from key executive Employees of the Company. Awards may be granted by the Administrative
Committee at any time and from time to time to new Participants, or to existing Participants, or to a greater or lesser number of Participants, and may include or exclude previous Participants, as the Administrative Committee shall determine. Except
as required by the Plan, Awards granted at different times need not contain similar provisions. 
 ARTICLE V 

GRANT OF PHANTOM STOCK 
 5.1. Shares Subject to the Plan. Subject to adjustments as provided in Article X, the shares of Common Stock that may be used for reference purposes with respect to Awards granted
under this Plan shall not exceed 2,000,000 shares of Common Stock, reduced by any shares of Common Stock used for reference purposes with respect to awards issued under the Alion Science and Technology Corporation Board of Directors Phantom Stock
Plan and the Alion Science and Technology Corporation Phantom Stock Plan (whether or not such awards have expired, terminated unexercised, or become unexercisable, or have been forfeited or otherwise terminated, surrendered or cancelled). No actual
shares of Common Stock are reserved hereunder. References to shares of Common Stock are for accounting and valuation purposes only, and not to grant any voting or other rights associated with ownership of Common Stock. 

  
 - 6 -

 5.2. Grant of Award. Subject to Section 5.3 and other applicable
provisions of the Plan, the Administrative Committee may at any time and from time to time grant Awards of Phantom Stock to eligible Participants, as it deems appropriate. The grant of an Award shall be authorized by the Administrative Committee and
shall be evidenced by a Performance Share Phantom Stock Agreement or a Retention Phantom Stock Agreement in a form approved by the Administrative Committee, between the Company and the Participant. Each Phantom Stock Agreement shall set forth its
Grant Date, the number of shares of Retention Phantom Stock awarded or the formula for determining the amount of Performance Share Phantom Stock payment based on a Target Performance Share Award (meaning the nominal shares awarded to a Participant
on a Grant Date pursuant to a Performance Share Phantom Stock Agreement), which shares are subject to vesting upon the achievement of a predetermined Fair Market Value price per share of the Company’s Common Stock. Failure to achieve the
minimum threshold price shall result in the vesting of no Performance Share Phantom Stock under the Plan. Achievement of a Fair Market Value per share equal to the predetermined target price per share shall result in the vesting of Performance Share
Phantom Stock equal to the Target Performance Share Award. Achievement of a Fair Market Value per share in excess of the predetermined target price per share shall result in the vesting of Performance Share Phantom Stock in excess of the number of
Target Performance Shares up to the maximum percentage specified in the underlying Performance Share Phantom Stock Agreement. Each such Phantom Stock Agreement shall be subject to the express terms and conditions of this Plan, and shall be subject
to such other terms and conditions that, in the reasonable judgment of the Administrative Committee, are appropriate and not inconsistent with this Plan.  
 5.3. Disqualified Persons. Notwithstanding the foregoing, no grant of Phantom Stock may be made to any “Disqualified Person” (within the meaning of Sections 409(p)(4)
and 4979A of the Code) for any period during which the Company maintains the Alion Science and Technology Corporation Employee Ownership, Savings and Investment Plan or any other employee stock ownership plan as described in and qualified under
Sections 4975(e)(7) and 401(a) of the Code, respectively. Any grant of Phantom Stock made in violation of this provision shall be null and void ab initio. In addition, no grant of Phantom Stock may be made to any eligible individual if and to
the extent that such grant would cause such individual to become a Disqualified Person. 
 ARTICLE VI 

RIGHT TO PAYMENT 
 6.1. Vesting.  
 (a) Performance Phantom
Stock. For grants of Performance Share Phantom Stock awarded November 9, 2005 and thereafter, a Participant shall have no right to any share of Performance Share Phantom Stock until it is vested, except in the event of the
Participant’s death, Disability, or involuntary Termination of Employment without Cause, or a Change in Control as set forth in the Performance Shares Phantom Stock Agreement at the Grant Date. Except as provided in Section 6.2, vesting
shall occur at the third anniversary of the Grant Date. At vesting, a predetermined Target Performance Share Award, stated in the Performance Shares Phantom Stock Agreement at Grant Date, combined with the Fair Market Value of Common Stock in effect
on the date of vesting, shall be used in the calculation of the actual number of shares of Performance Shares Phantom Stock that will be vested for all Participants. 

  
 - 7 -

 (b) Retention Phantom Stock. For grants of Retention Phantom Stock
awarded November 9, 2005 and thereafter, a Participant shall have no right to any share of Retention Phantom Stock until it is vested, except in the event of the Participant’s death, Disability, or involuntary Termination of Employment
without Cause, or a Change in Control as set forth in the Retention Phantom Stock Agreement at the Grant Date. Vesting shall occur in accordance with the applicable provisions expressed in the individual Retention Phantom Stock Agreements.

 6.2. Payment Date and Vesting Events.  

(a) Payment Date. The Payment Date is the date certain specified in the Performance Share Phantom Stock Agreement
or Retention Phantom Stock Agreement executed by the Company and the Participant as of the Grant Date, for the conversion of Performance Share Phantom Stock and/or Retention Phantom Stock into an amount certain in cash. The Payment Date shall not be
earlier than the date on which the Participant becomes 100% vested in the Performance Share Phantom Stock or Retention Phantom Stock covered by the respective Phantom Stock Agreement, except as provided below with respect to the Participant’s
death, Disability, Termination of Employment or Change in Control. Nothing in this Plan shall be construed to require an identical Payment Date for any grants of Performance Share Phantom Stock or Retention Phantom Stock as of a particular date.

 (b) Termination of Employment. Except as set forth in the respective Phantom Stock Agreement or
elsewhere in the Plan, a Participant who has a Termination of Employment shall forfeit his or her rights to all unvested Awards. 
 (c) Death. If a Participant dies prior to terminating employment with the Company, the Participant’s Beneficiary shall be paid out any vested amount as set forth in the respective Phantom
Stock Agreement. Except as otherwise provided in the applicable Phantom Stock Agreement, the Payment Date shall be the date of the Participant’s death. 
 (d) Disability. If a Participant incurs a Termination of Employment due to Disability, the Participant shall be paid out any vested amount as set forth in the respective Phantom Stock Agreement.
Except as otherwise provided in the applicable Phantom Stock Agreement, the Payment Date shall be the date of the Participant’s Termination of Employment due to Disability. 

(e) Change in Control. Upon a Change in Control, Participants shall immediately vest in the Target Performance
Share Award and Retention Phantom Stock Award as and to the extent specified in the respective Phantom Stock Grant Agreements. Except as otherwise provided in the applicable Phantom Stock Agreement, the Payment Date shall be the date of the Change
in Control. 
 (f) Disqualified Persons. If Participant is or becomes a Disqualified Person as described
in Section 5.3 above, then the full amount of any then outstanding Award that has not yet vested shall be forfeited; and no amount of an Award shall become vested, if, as a result of such vesting, the Participant would become a Disqualified
Person and the vesting of any such Award would result in a “nonallocation year” (within the meaning of Code Section 409(p)(3)).

 ARTICLE VII  
 PAYMENT OF PHANTOM STOCK BENEFITS 
 7.1. Amount and Timing of
Payment.  
 (a) Retention Phantom Stock. For grants of Retention Phantom Stock, a Participant
shall be entitled to a cash payment on the Payment Date, equal to the number of vested shares of Retention Phantom Stock multiplied by the Fair Market Value as of the Valuation Date coincident with or immediately preceding the Payment Date;
provided, however, that in the case of payment due to a Change in Control, the Fair Market Value as of the date of the Change in Control or the immediately preceding Valuation Date, whichever is higher, shall be used. Except as provided below in
this Article VII, the Company shall make payment on a Payment Date by the delivery to the Participant of cash in a lump sum sixty (60) days after the Payment Date, less any applicable withholdings required by the Code or other similar
regulations. 
 (b) Performance Share Phantom Stock. For grants of Performance Share Phantom Stock, a
Participant shall be entitled to a cash payment on a Payment Date, equal to the amount generated by the calculation of the vested Target Performance Share Award contained in individual Performance Share Phantom Stock Agreements; provided, however,
that in the case of payment due to a Change in Control, the Fair Market Value as of the date of the Change in Control or the immediately preceding Valuation Date, whichever is higher, shall be used. Except as provided below in this Article VII, the
Company shall make payment on a Payment Date by the delivery to the Participant of cash in a lump sum sixty (60) days after the Payment Date, less any applicable withholdings required by the Code or other similar regulations. 

(c) Compliance with Code Section 409A. No payment shall be made in violation of Section 409A or any other
applicable provisions of the Code and the rules and regulations thereunder. 
 7.2. Acceleration of Payment
Date. Notwithstanding the foregoing, the Payment Date of a vested Award may be accelerated, with the consent of the Administrative Committee, under the following circumstances: 

(a) Compliance with Domestic Relations Order: To permit payment to an individual other than the Participant as
necessary to comply with the provisions of a domestic relations order (as defined in Code Section 414(p)(1)(B)); 
 (b) Conflicts of Interest: To permit payment as necessary to comply with the provisions of a Federal government ethics agreement or to avoid violation of applicable Federal, state, local or foreign
ethics law or conflicts of interest law; 

  
 - 9 -

 (c) Payment of Employment Taxes: To permit payment of federal
employment taxes under Code Sections 3101, 3121(a) or 3121(v)(2), or to comply with any federal tax withholding provisions or corresponding withholding provisions of applicable state, local, or foreign tax laws as a result of the payment of federal
employment taxes, and to pay the additional income tax at source on wages attributable to the pyramiding Code Section 3401 wages and taxes; 
 (d) Code Section 409(p): To prevent the occurrence of a nonallocation year (within the meaning of Code Section 409(p)(3)) in the plan year of an employee stock ownership plan next
following the Plan Year in which such payment is made, provided that the amount distributed may not exceed 125% of the minimum amount of distribution necessary to avoid the occurrence of a nonallocation year; or 

(e) Tax Event: Upon a good faith, reasonable determination by the Company, upon advice of counsel, that the Plan or
an Award fails to meet the requirements of Code Section 409A and regulations thereunder. Such payment may not exceed the amount required to be included in income as a result of the failure to comply with the requirements of Code
Section 409A. 
 7.3. Delay of Payments. If the Committee reasonably determines that the making of any
payment required under the Plan at the date specified in the Plan would jeopardize the ability of the Company to continue as a going concern, the payment will be treated as made upon the date specified under the Plan if the payment is made during
the first taxable year of the Company in which the making of the payment would not have such effect. In addition, payment may be delayed (without imputation of earnings, interest or other gains or losses after the Payment Date) solely to the extent
necessary under the following circumstances, provided that payment is made as soon as possible within the first taxable year of the Participant after the reason for delay no longer applies: 

(a) Payments Subject to Section 162(m). The Company reasonably anticipates that its deduction with respect to
such payment would otherwise be limited or eliminated by application of Code Section 162(m). 
 (b)
Payments that Would Violate Law. The Company reasonably determines that payment would violate Federal securities laws or other applicable law. 
 (c) Other Permitted Event: Upon such other events and conditions as the Commissioner of Internal Revenue shall prescribe in generally applicable guidance. 

  
 - 10 -

 7.4. Election to Defer Benefits. A Participant hereunder who is also a
participant in, or eligible to become a participant in, the Alion Science and Technology Corporation Executive Deferred Compensation Plan (the “Deferred Compensation Plan”), may elect to defer receipt of all or a portion of the Plan
benefit otherwise payable to him or her by electing to contribute such benefit to the Deferred Compensation Plan in the amount that would otherwise have been payable on the applicable Payment Date under Section 7.1. Any such election shall be
made in a writing acceptable to the Administrative Committee and filed with the Administrative Committee at least one year prior to the Payment Date; provided, however, that an election to defer the receipt of a payment under this Section 7.6
that would, absent such a deferral election, be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) must be made as of a date permitted by the Administrator that is at least one year prior to the
date such payment ceases to be subject to a substantial risk of forfeiture. Such election shall become effective upon the applicable Payment Date and shall specify a time for payment and method of distribution available under the Deferred
Compensation Plan, provided that such election may not provide for a time of distribution (other than as a result of Termination of Employment, death or Disability) earlier than five years after the Payment Date. If the Participant has elected a
time of payment or method of distribution under the Deferred Compensation Plan that will apply to amounts deferred hereunder and is different from the time or method of distribution specified in Section 7.1 with respect to any distribution
event, the deferral election under this Section 7.4 shall be treated as a change election under Treasury Regulation Section 1.409A-2(b) and Section 5.2(b) of the Deferred Compensation Plan. This Section 7.4 shall not apply to
amounts withheld under Section 7.6. 
 7.5. Discharge. Any payment made by the Company in good faith
in accordance with the provisions of this Plan and a Participant’s Phantom Stock Agreement shall fully discharge the Company from all further obligations with respect to such payment and such Phantom Stock Agreement. 

7.6. Withholding. The Company shall have the right to deduct from all amounts paid pursuant to the Plan any Federal,
State or local income tax, social security contribution or other payroll taxes required by law, whether domestic or foreign, to be withheld with respect to such payments. The Company shall also have the right to deduct FICA contributions required at
vesting from normal salary and wages or other cash compensation to be paid to the Participant. 
 ARTICLE VIII

 AMENDMENT AND TERMINATION 
 8.1. Amendment. The Board may amend the Plan at any time and from time to time, provided that (a) no amendment shall deprive any person of any rights granted under the Plan
before the effective date of such amendment without such person’s consent; and (b) amendments may be subject to shareholder approval to the extent needed to comply with applicable law. Notwithstanding the foregoing, the Board may
unilaterally amend the Plan or any outstanding Award subject to Code Section 409A as necessary to cause the Plan or such Award to comply with Code Section 409A. 
 8.2. Termination. The Board reserves the right to terminate the Plan in whole or in part at any time, without the consent of any person granted any rights under the Plan. Termination
of the Plan shall not affect the Administrative Committee’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. Notwithstanding the foregoing, termination
of the Plan shall not result in the acceleration of payment of any Award except as permitted by the Administrative Committee and consistent with the requirements of Code Section 409A. 

  
 - 11 -

 ARTICLE IX 
 TERM 
 The Plan shall be effective from the date that this Plan is approved
by the Board. Unless sooner terminated by action of the Board, the Plan will terminate on November 9, 2016, but Awards granted before this termination date will continue to be effective in accordance with their terms and conditions. 

ARTICLE X 

TRANSACTIONS 
 10.1. Adjustment of Number and Price of Shares. Any other provision of the Plan notwithstanding, if through, or as a result of, any merger, consolidation, sale of all or substantially
all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, the outstanding shares of Common Stock are increased or decreased or are exchanged
for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or
other securities, the Administrative Committee shall make an appropriate or proportionate adjustment in the Awards as it deems appropriate, in its sole discretion. The adjustment by the Administrative Committee shall be final, binding and
conclusive. 
 10.2. Adjustments Due to Special Circumstances. The Administrative Committee is
authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events affecting the Company, or the financial statements of the Company, or of changes in applicable laws,
regulations, or accounting principles, whenever the Administrative Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the
Plan.  
 10.3. Compliance with Code Section 409A. Notwithstanding the foregoing, the
Administrative Committee shall not make an adjustment under this Article X which results in a violation of Code Section 409A. 
 ARTICLE XI 
 MISCELLANEOUS PROVISIONS 

11.1. No Guarantee of Employment. Neither the Plan nor any Award granted under the Plan shall confer upon any Participant
any right with respect to continuance of employment by the Company. Participation in the Plan shall not be construed to confer upon any Participant the legal right to be retained in the employ of the Company or give any person any right to any
payment whatsoever, except to the extent of the benefits provided for hereunder. Each Participant shall remain subject to discharge to the same extent as if this Plan had never been adopted. Nothing in this Plan shall prevent, interfere with or
limit in any way the right of the Company to terminate a Participant’s employment at any time, whether or not such termination would result in: (a) the failure of any Award to vest; (b) the forfeiture of any unvested or vested portion
of any Award under the Plan; and/or (c) any other adverse effect on the Participant’s interests under the Plan. 

  
 - 12 -

 11.2. No Rights as a Shareholder. A Participant shall not have any
rights as a shareholder with respect to any shares of Phantom Stock.

Plan Administrative Committee. No member of the Board or the Administrative Committee, nor any officer or Employee of the Company acting on behalf of the Board or the Administrative Committee, shall be personally liable for any action,
determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Board or the Administrative Committee and each and any officer or Employee of the Company acting on their behalf shall, to the extent
permitted by law, be fully indemnified and protected by the Company in respect of any such action, determination, or interpretation. 
 11.4. Effect of the Plan. Neither the adoption of this Plan nor any action of the Board or the Administrative Committee shall be deemed to give any person any right to be granted an
Award or any other rights except as may be evidenced by a Phantom Stock Agreement, or any amendment thereto, duly authorized by the Administrative Committee and executed on behalf of the Company, and then only to the extent and upon the terms and
conditions expressly set forth therein. 
 11.5. Non-Assignability. Phantom Stock granted to a
Participant may not be transferred or assigned other than by will or by the laws of descent and distribution. If the Participant attempts to alienate, assign, pledge, hypothecate, or otherwise dispose of his or her Phantom Stock or any right
thereunder, except as provided for in the Plan or the Phantom Stock Agreement, or in the event of any levy, attachment, execution, or similar process upon the right or interest conferred by this Plan or the Phantom Stock Agreement, the
Administrative Committee shall terminate the Participant’s Phantom Stock by notice to him or her, and it shall thereupon become null and void.  
 11.6. Restrictive Legends. The Company may at any time place legends referencing any restrictions described in the Phantom Stock Agreement and any applicable federal or state
securities law restrictions on all Awards. 
 11.7. Company Charter and Bylaws. The Plan is subject
to the charter and by-laws of the Company, as they may be amended from time to time. 
 11.8. No Trust or
Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other person. To the extent that any
Participant or other person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company; however, in the event of commencement of a
voluntary or involuntary case of bankruptcy against or by the Company, all vested and unvested Awards made hereunder shall be canceled and void. 
 11.9. Governing Law. All questions arising with respect to this Plan and any Phantom Stock Agreement executed hereunder shall be determined by reference to the laws of the State of Delaware
in effect at the time of their adoption and execution, respectively, without implementing its laws regarding choice of law.

 2.22. “Termination of Employment” means cessation of performance of
services for the Company. For purposes of maintaining a Participant’s continuous status as an Employee and accrual of rights under any Award granted pursuant to the Plan, transfer of an Employee among Alion and any of its Affiliates shall not
be considered a Termination of Employment with the Company. A Participant will not be deemed to have incurred a Termination of Employment while he or she is on military leave, sick leave, or other bona fide leave of absence (such as temporary
employment by the government) if the period of such leave does not exceed six months or such longer period as the Participant’s right to reemployment with the Company or an Affiliate is provided either by statute or by contract. If the period
of leave exceeds six months and the Participant’s right to reemployment is not provided either by statute or by contract, the Termination of Employment will be deemed to occur on the first date immediately following such six-month period. For
the avoidance of doubt, and by way of example only, if a Participant works for a wholly-owned subsidiary of the Company, then a sale of the subsidiary by the Company would be regarded as a Termination of Employment of such Participant for purposes
of this Plan, notwithstanding the Participant’s continued employment with that former subsidiary. Whether an Employee of the Company incurs a termination of employment with the Company will be determined in accordance with the requirements of
Code Section 409A. 
 2.23. “Valuation Date” shall mean a date as of which the Fair Market Value of Common Stock
of the Company is determined. 
 ARTICLE III

 3.1. General. The Plan shall be
administered by the Administrative Committee. The Administrative Committee shall have the full and final authority, in its discretion, to interpret conclusively the provisions of the Plan; to adopt such rules for carrying out the Plan as it may deem

 3.5. Effect of Administrative
Committee’s Decision. All actions taken and decisions and determinations made by the Administrative Committee on all matters relating to the Plan pursuant to the powers vested in it hereunder shall be in the Administrative
Committee’s sole and absolute discretion and shall be conclusive and binding on all parties concerned, including the Company, its stockholders, any Participants in the Plan and any other employee of the Company, and their respective successors
in interest. 
 ARTICLE IV 
 PARTICIPATION

the Administrative Committee in its sole discretion from key executive Employees of the Company. Awards may be granted by the Administrative Committee at any time and from time to time to new Participants, or to existing Participants, or to a

 GRANT OF PHANTOM STOCK 
 5.1. Shares Subject to the
Plan. Subject to adjustments as provided in Article X, the shares of Common Stock that may be used for reference purposes with respect to Awards granted under this Plan shall not exceed 2,000,000 shares of Common Stock, reduced by any shares
of Common Stock used for reference purposes with respect to awards issued under the Alion Science and Technology Corporation Board of Directors Phantom Stock Plan and the Alion Science and Technology Corporation Performance Shares and Retention
Phantom Stock Plan (whether or not such awards have expired, terminated unexercised, or become unexercisable, or have been forfeited or otherwise terminated, surrendered or cancelled). No actual shares of Common Stock are reserved hereunder.
References to shares of Common Stock are for accounting and valuation purposes only, and not to grant any voting or other rights associated with ownership of Common Stock. 

5.2. Grant of Award. Subject to Section 5.3 and other applicable provisions of the Plan, the Administrative
Committee may at any time and from time to time grant Awards of Phantom Stock to eligible Participants, as it deems appropriate. The grant of an Award shall be authorized by the Administrative Committee and shall be evidenced by a Phantom Stock
Agreement in a form approved by the Administrative Committee, between the Company and the Participant. Each such Phantom Stock Agreement shall set forth its Grant Date, the number of shares of Phantom Stock awarded, and the vesting provisions. Each
such Phantom Stock Agreement shall be subject to the express terms and conditions of this Plan, and shall be subject to such other terms and conditions that, in the reasonable judgment of the Administrative Committee, are appropriate and not
inconsistent with this Plan.  
 5.3. Disqualified Persons. Notwithstanding the foregoing, no grant
of Phantom Stock may be made to any “Disqualified Person” (within the meaning of Sections 409(p)(4) and 4979A of the Code, as added by the Economic Growth and Tax Relief Reconciliation Act of 2001) for any period during which
the Company maintains the Alion Science and Technology Corporation Employee Ownership, Savings and Investment Plan or any other employee stock ownership plan as described in and qualified under Section 4975(e)(7) and 401(a) of the Code,
respectively. Any grant of Phantom Stock made in violation of this provision shall be null and void ab initio. In addition, no grant of Phantom Stock may be made to any eligible individual if and to the extent that such grant would cause such
individual to become a Disqualified Person.

 ARTICLE VI 
 RIGHT TO PAYMENT 
 6.1. Vesting. A Participant shall

with the following schedule: 
  

					
	Anniversary from Grant Date	  	Vested Amount

 6.2. Termination and Forfeiture of Awards. If a Participant incurs a Termination of
Employment on or before becoming 100% vested in an Award, he or she shall forfeit any unvested portion of the Award, except as provided below: 
 (a) Voluntary Termination of Employment. If a Participant voluntarily terminates employment with the Company, then such Participant shall forfeit all rights to all unvested Awards, unless such
termination is for Good Reason, as defined in the Participant’s Employment Agreement (but for this purpose only, without regard to whether the occurrence of one of the events is during the Protected Period, as defined by the Employment
Agreement). If a Participant voluntarily terminates employment with the Company for Good Reason, then such Participant shall immediately vest in a prorated portion of his or her unvested Awards issued prior to November 9, 2005, based on a ratio
the numerator of which is the number of months from the Grant Date through the end of the month of such termination and the denominator of which is sixty (60). For Awards made on or after November 9, 2005, if a Participant voluntarily
terminates employment with the Company for Good Reason, then such Participant shall immediately vest in a prorated portion of his or her outstanding Awards equal to the greater of the amount vested under Section 6.1(b) and the amount determined
based on a ratio the numerator of which is the number of months from the Grant Date through the end of the month of such termination and the denominator of which is sixty (60), 

  
 - 7 -

 (b) Involuntary Termination of Employment Without Cause. If a
Participant is involuntarily terminated from employment with the Company for any reason other than for Cause or Just Cause, then he or she shall immediately vest in a prorated portion of his or her unvested Awards issued prior to November 9,
2005, based on a ratio the numerator of which is the number of months from the Grant Date through the end of the month of such termination and the denominator of which is sixty (60). For Awards made on or after November 9, 2005, if a
Participant is involuntarily terminated from employment with the Company for any reason other than for Cause or Just Cause, then such Participant shall immediately vest in a prorated portion of his or her outstanding Awards equal to the greater of
the amount vested under Section 6.1(b) and the amount determined based on a ratio the numerator of which is the number of months from the Grant Date through the end of the month of such termination and the denominator of which is sixty (60).

 (c) Death or Disability. If the Participant’s Termination of Employment is due to death or
Disability, any outstanding Awards at the time of such Termination of Employment shall immediately become 100% vested. 
 (d) Change in Control. If the Participant incurs a Termination of Employment for any reason on or after a Change in Control, any Awards granted prior to such Change in Control that are outstanding
at the time of such Termination of Employment shall immediately become 100% vested. 
 (e) Disqualified
Persons. If Participant is or becomes a Disqualified Person as described in Section 5.3 above, then the full amount of any then outstanding Award that has not yet vested shall be forfeited; and no amount of an Award shall become vested, if,
as a result of such vesting, the Participant would become a Disqualified Person. 
 ARTICLE VII 

PAYMENT OF PHANTOM STOCK BENEFITS 
 7.1. Exercise of Awards Vested on or before December 31, 2004. A Participant may elect to exercise any shares of Phantom Stock granted and vested on or before December 31,
2004, by filing a written election to exercise with the Administrative Committee at least six (6) months in advance of the Exercise Date and at least three (3) months in advance of the Valuation Date that will apply to such Exercise Date;
provided, however, that the Phantom Stock that becomes vested on November 12, 2004 may be exercised as of November 12, 2004, based upon an election by the Participant filed no later than August 2, 2004. Notwithstanding the foregoing,
the Exercise Date of vested shares of Phantom Stock shall not be earlier than the date the Phantom Stock becomes vested nor later than the earliest of (1) the date of the occurrence of a termination event described in Section 6.2 or any
other Termination of Employment of the Participant; (2) the date of a Change in Control; or (3) the fifth
(5th) anniversary of the Grant Date of the Phantom
Stock. An election to exercise Phantom Stock shall be made in such form and at such time as the Administrative Committee deems acceptable.  

  
 - 8 -

 7.2. Payment of Awards Granted before November 9, 2005, and Vesting on or
after January 1, 2005. A Participant granted Phantom Stock under this Plan before November 9, 2005, but not vesting until on or after January 1, 2005, shall be entitled to a cash payment on the Surrender Date, which shall be
the earlier of (i) the date on which the Participant becomes fully vested in the Award, or (ii) the date of the Participant’s Termination of Employment. Notwithstanding the foregoing, (a) the Surrender Date of a vested Award may
be accelerated, with the consent of the Administrative Committee, under the circumstances set forth in Section 7.3(a) through (d); and (b) a Participant may elect, in accordance with Internal Revenue Service Notice 2005-1, Q-20(a), to
receive payment of any Awards granted before November 9, 2005, and vesting on or after January 1, 2005, calendar year 2005 or, if later, the taxable year in which the amounts are earned and vested. Any such election shall be made in a form
acceptable to the Administrative Committee and filed with the Administrative Committee no later than December 31, 2005. 
 7.3. Payment of Awards Granted on or after November 9, 2005. The Administrative Committee may, in its discretion, permit a Participant to elect whether the Surrender Date with
respect to an Award granted on or after November 9, 2005 shall occur (a) with respect to any portion of an Award which has become vested under Section 6.1(b), the date on which such portion of the Award becomes vested; or (b) the
date on which the entire amount of the Award becomes 100% vested or, if earlier, upon the Participant’s Termination of Employment. Any such election shall be made in a writing acceptable to the Administrative Committee and filed with the
Administrative Committee prior to the Award Grant Date; provided, however, that in the case of a new Participant, such election shall be made within 30 days after the Participant becomes eligible to participate in the Plan. If the Administrative
Committee does not permit an election under this provision, or if a Participant fails to make a timely election to the contrary hereunder, the Participant shall be deemed to have elected the Surrender Date described in clause (b) above.
Notwithstanding the foregoing, the Surrender Date of a vested Award may be accelerated, with the consent of the Administrative Committee, under the following circumstances: 

(a) Compliance with Domestic Relations Order: To permit payment to an individual other than the Participant as
necessary to comply with the provisions of a domestic relations order (as defined in Code Section 414(p)(1)(B)); 
 (b) Conflicts of Interest: To permit payment as necessary to comply with the provisions of a certificate of divestiture (as defined in Code Section 1043(b)(2)); 

(c) Payment of Employment Taxes: To permit payment of federal employment taxes under Code Sections 3101, 3121(a) or
3121(v)(2), or to comply with any federal tax withholding provisions or corresponding withholding provisions of applicable state, local, or foreign tax laws as a result of the payment of federal employment taxes, and to pay the additional income tax
at source on wages attributable to the pyramiding Code Section 3401 wages and taxes; or 
 (d) Tax
Event: Upon a good faith, reasonable determination by the Company, upon advice of counsel, that the Plan or an Award fails to meet the requirements of Code Section 409A and regulations thereunder. Such payment may not exceed the amount
required to be included in income as a result of the failure to comply with the requirements of Code Section 409A. 

  
 - 9 -

 7.4. Amount and Timing of Payment. A Participant shall be entitled to a
cash payment upon exercise or surrender (as applicable) of an Award equal to the number of vested units of Phantom Stock subject to surrender, multiplied by the Fair Market Value as of the Valuation Date coincident with or immediately preceding the
Surrender Date; provided, however, that, in the case of an Award outstanding on the date of a Change in Control, the Fair Market Value of such Phantom Stock units shall be determined based upon the Fair Market Value of Common Stock as of the
Valuation Date coincident with or immediately preceding the Surrender Date, or the Valuation Date coincident with or immediately preceding the date of the Change in Control, whichever produces the higher Fair Market Value.  

7.5. Time of Payment. Except as provided in Section 7.6, the Company shall make payment of
the amount receivable upon the exercise of an Award by the delivery of cash in a lump sum within sixty days after the Exercise Date of an Award described in Section 7.1, or as soon as practicable after the Surrender Date of an Award described
in Section 7.2 or 7.3, as applicable, but in any event within 2 1/2 months after the end of the Plan Year in which the Surrender Date occurs. Notwithstanding the foregoing, payment under
this Section 7.5 may be delayed (without imputation of earnings, interest or other gains or losses after the Surrender Date) solely to the extent necessary under the following circumstances, provided that payment is made as soon as possible
after the reason for delay no longer applies: 
 (a) Unforeseeable
Administrative or Financial Cause. The Compensation Committee reasonably determines that (1) it is administratively impracticable to make payment by the end of the applicable 2 1/2 month period or that making such payment will jeopardize the solvency of the Company, and (2) such impracticability or insolvency was unforeseeable as of the Grant Date. 

(b) Payments Subject to Section 162(m). The Company reasonably anticipates that its deduction with respect to
such payment would otherwise be limited or eliminated by application of Code Section 162(m). 
 (c)
Payments that Would Violate Loan Covenant or Similar Contractual Requirement. The Company reasonably anticipates that making the payment will violate a term of a loan agreement to which the Company is a party, including any ESOP loan
agreement, or other similar contract to which the Company is a party, and such violation will cause material harm to the Company. 
 (d) Payments that Would Violate Law. The Company reasonably determines that payment would violate Federal securities laws or other applicable law. 

  
 - 10 -

 7.6. Election to Defer Benefits. If a Participant has
elected as the Exercise Date for Phantom Stock granted and vested on or before December 31, 2004, the fifth
(5th) anniversary of the Grant Date of such Phantom
Stock, and the Participant is also a participant in the Alion Science and Technology Corporation Executive Deferred Compensation Plan (the “Deferred Compensation Plan”), he or she may elect, at least 180 days prior to such Exercise
Date, to defer receipt of all or a portion of the Plan benefit through a contribution to the Deferred Compensation Plan equal to the amount that would otherwise have been payable under Section 7.2. If a Participant has elected, or is deemed to
have elected, as the Surrender Date of an Award under Section 7.2 or 7.3 the date on which the entire amount of the Award becomes 100% vested, then the Participant may elect to have the amount of payment for such Award that would otherwise be
made upon the Surrender Date deferred into the Deferred Compensation Plan, provided that he or she has not incurred a Termination of Employment and is then (or is then eligible to become) a participant in the Deferred Compensation Plan. Any
such election shall be made in a writing acceptable to the Administrative Committee and filed with the Administrative Committee at least one year prior to the Surrender Date. Such election shall become effective upon the Surrender Date and shall
specify a time for payment and method of distribution available under the Deferred Compensation Plan, provided that such election may not provide for a time of distribution (other than as a result of Termination of Employment, death or Disability)
earlier than five years after the Surrender Date. 
 7.7. Discharge. Any payment made by the Company in good
faith in accordance with the provisions of this Plan and a Participant’s Phantom Stock Agreement shall fully discharge the Company from all further obligations with respect to such payment and the Phantom Stock Agreement. 

7.8. Compliance with Code Section 409A. No payment shall be made in violation of Section 409A or any other
applicable provisions of the Code and the rules and regulations thereunder. 
 7.9. Withholding. The
Company shall have the right to deduct from all amounts paid pursuant to the Plan any Federal, State or local income tax, social security contribution or other payroll taxes required by law, whether domestic or foreign, to be withheld with respect
to such payments. The Company shall also have the right to deduct FICA contributions required at vesting. 
 ARTICLE
VIII 
 AMENDMENT AND TERMINATION 
 8.1. Amendment. The Board may amend the Plan at any time and from time to time, provided that (a) no amendment shall deprive any person of any rights granted under the Plan
before the effective date of such amendment without such person’s consent; and (b) amendments may be subject to shareholder approval to the extent needed to comply with applicable law. Notwithstanding the foregoing, the Board may
unilaterally amend the Plan or any outstanding Award subject to Section 409A as necessary to cause the Plan or such Award to comply with Code Section 409A. 
 8.2. Termination. The Board reserves the right to terminate the Plan in whole or in part at any time, without the consent of any person granted any rights under the Plan. Termination
of the Plan shall not affect the Administrative Committee’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. Notwithstanding the foregoing, termination
of the Plan shall not result in the acceleration of payment of any Award except as permitted by the Administrative Committee and consistent with the requirements of Code Section 409A.

dividend, stock split, reverse stock split or other similar transaction, the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional
shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, the Administrative Committee shall make an appropriate or proportionate
adjustment in the Awards as it deems appropriate, in its sole discretion. The adjustment by the Administrative Committee shall be final, binding and conclusive.

recognition of unusual or nonrecurring events affecting the Company, or the financial statements of the Company, or of changes in applicable laws, regulations, or accounting principles, whenever the Administrative Committee determines that such
adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. 
 10.3. Compliance with Code Section 409A. Notwithstanding the foregoing, the Administrative Committee shall not make an adjustment under this Article X which results in a

 ARTICLE XI 

MISCELLANEOUS PROVISIONS 
 11.1. No Guarantee of Employment. Neither the Plan nor any Award granted under the Plan shall confer upon any Participant any right with respect to continuance of employment by the Company.
Participation in this Plan shall not be construed to confer upon any Participant the legal right to be retained in the employ of the Company or give any person any right to any payment whatsoever, except to the extent of the benefits provided for
hereunder. Each Participant shall remain subject to discharge to the same extent as if this Plan had never been adopted. Nothing in this Plan shall prevent, interfere with or limit in any way the right of the Company to terminate a
Participant’s employment at any time, whether or not such termination would result in: (a) the failure of any Award to vest; (b) the forfeiture of any unvested or vested portion of any Award under the Plan; and/or (c) any other
adverse effect on the Participant’s interests under the Plan.

Plan Administrative Committee. No member of the Board or the Administrative Committee, nor any officer or Employee of the Company acting on behalf of the Board or the Administrative Committee, shall be personally liable for any action,

permitted by law, be fully indemnified and protected by the Company in respect of any such action, determination, or interpretation. 
 11.4. Effect of the Plan. Neither the adoption of this Plan nor any action of the Board or the Administrative Committee shall be deemed to give any person any right to be granted an
Award or any other rights except as may be evidenced by a Phantom Stock Agreement, or any amendment thereto, duly authorized by the Administrative Committee and executed on behalf of the Company, and then only to the extent and upon the terms and
conditions expressly set forth therein. 
 11.5. Non-Assignability. Phantom Stock granted to a
Participant may not be transferred or assigned other than by will or by the laws of descent and distribution. If the Participant attempts to alienate, assign, pledge, hypothecate, or otherwise dispose of his Phantom Stock or any right thereunder,
except as provided for in this Plan or the Phantom Stock Agreement, or in the event of any levy, attachment, execution, or similar process upon the right or interest conferred by this Plan or the Phantom Stock Agreement, the Administrative Committee

 11.8. No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the
Company and a Participant or any other person. To the extent that any Participant or other person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any unsecured general
creditor of the Company; however, in the event of commencement of a voluntary or involuntary case of bankruptcy against or by the Company, all vested and unvested Awards made hereunder shall be canceled and void.
