ALION SCIENCE AND TECHNOLOGY CORPORATION

PERFORMANCE SHARES AND RETENTION PHANTOM STOCK PLAN

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 the “Company”), effective as of January 24,
2005. The Plan is hereby amended and restated effective November 1, 2007 to comply with final
regulations under Code Section 409A; provided, however, that any provision herein required to be
effective as of an earlier date in order for the Plan to comply with Code Section 409A shall be
effective as of such earlier date.

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.

 

 

 

2.4. “Beneficiary” shall mean one or more persons, trusts, estates or other entities,
designated by the Participant to receive benefits under this Plan upon his or her death. The
Administrative Committee may establish such forms and procedures that it deems appropriate for the
designation of a Beneficiary. If the Participant has not designated a Beneficiary, the
Participant’s Beneficiary shall be his or her estate.

2.5. “Board” means the Board of Directors of the Company.

2.6. “Cause” or “Just Cause” shall have the same meaning as defined in the relevant
Participant’s Employment Agreement.

2.7. “Change in Control” shall mean and shall be deemed to have occurred as of the date of the
first to occur of the following events:

(a) any Person or Group acquires stock of Alion that, together with stock held by such
Person or Group, constitutes more than fifty percent (50%) of the total Fair Market Value or
total voting power of the stock of Alion. However, if any Person or Group is considered to
own more than fifty percent (50%) of the total Fair Market Value or total voting power of
the stock of Alion, the acquisition of additional stock by the same Person or Group is not
considered to cause a Change in Control of Alion. An increase in the percentage of stock
owned by any Person or Group as a result of a transaction in which Alion acquires its stock
in exchange for property will be treated as an acquisition of stock for purposes of this
subsection. This subsection applies only when there is a transfer of stock of Alion (or
issuance of stock of Alion) and stock in Alion remains outstanding after the transaction;

(b) any Person or Group acquires (or has acquired during the 12-month period ending on
the date of the most recent acquisition by such Person or Group) ownership of stock of Alion
possessing thirty percent (30%) or more of the total voting power of the stock of Alion;

(c) a majority of members of the Board is replaced during any 12-month period by
Directors whose appointment or election is not endorsed by a majority of the members of the
Board prior to the date of the appointment or election; or

(d) any Person or Group acquires (or has acquired during the 12-month period ending on
the date of the most recent acquisition by such Person or Group) assets from Alion that have
a total gross fair market value equal to or more than forty percent (40%) of the total gross
fair market value of all of the assets of Alion immediately prior to such acquisition or
acquisitions. For this purpose, gross fair market value means the value of the assets of
Alion, or the value of the assets being disposed of, determined without regard to any
liabilities associated with such assets. However, no Change in Control shall be deemed to
occur under this subsection (d) as a result of a transfer to:

(i) A shareholder of Alion (immediately before the asset transfer) in exchange
for or with respect to its stock;

(ii) An entity, fifty percent (50%) or more of the total value or voting power
of which is owned, directly or indirectly, by Alion;

 

- 2 -

 

(iii) A Person or Group that owns, directly or indirectly, fifty percent (50%)
or more of the total value or voting power of all the outstanding stock of Alion; or

(iv) An entity, at least fifty percent (50%) of the total value or voting power
of which is owned, directly or indirectly, by a person described in clause (iii)
above.

For these purposes, the term “Person” shall mean an individual, corporation,
association, joint-stock company, business trust or other similar organization, partnership,
limited liability company, joint venture, trust, unincorporated organization or government or
agency, instrumentality or political subdivision thereof (other than an employee benefit trust
established or maintained for the benefit of employees of the Company). The term “Group”
shall have the meaning set forth in Rule 13d-5 of the Securities Exchange Commission (“SEC”),
modified to the extent necessary to comply with Treasury Regulation Section 1.409A-3(i)(5), or any
successor thereto in effect at the time a determination of whether a Change in Control has occurred
is being made. If any one Person, or Persons acting as a Group, is considered to effectively
control the Corporation as described in subsections (b) or (c) above, the acquisition of additional
control by the same Person or Persons is not considered to cause a Change in Control.

2.8. “Code” means the Internal Revenue Code of 1986, as amended, and related rules,
regulations and interpretations.

2.9. “Common Stock” means the voting common stock, $0.01 par value per share, of the Company,
subject to adjustments pursuant to the Plan.

2.10. “Company” means Alion Science and Technology Corporation, a Delaware corporation.

2.11. “Disability” means that the Participant: (a) is unable to engage in any substantial
gainful activity by reason of any medically determinable physical or mental impairment that can be
expected to result in death or can be expected to last for a continuous period of not less than 12
months; (b) is, by reason of any medically determinable physical or mental impairment that can be
expected to result in death or can be expected to last for a continuous period of not less than 12
months, receiving income replacement benefits for a period of not less than 3 months under an
accident and health plan covering employees of the Company; or (c) has been determined to be
totally disabled by the Social Security Administration.

2.12. “Employee” shall mean any person who is employed by the Company, is on the Company’s
payroll, and whose wages are subject to withholding under the Federal Insurance Contributions Act,
codified in Code Section 3121, or would be subject to such withholding if paid in the US.

2.13. “Employer” shall mean the Company and any Affiliate that, with the consent of the
Company, elects to participate in the Plan and any successor entity that adopts the Plan. If
any such entity withdraws, is excluded from participation in the Plan or terminates its
participation in the Plan, such entity shall thereupon cease to be an Employer.

 

- 3 -

 

2.14. “Employment Agreement” shall mean the employment contract specifying the terms of a
Participant’s employment with his or her Employer.

2.15. “Fair Market Value” on any given date means the value of one share of Common Stock, as
determined by the Administrative Committee in its sole discretion, based upon the most recent
valuation of the Common Stock made by an independent appraisal that meets the requirements of Code
Section 401(a)(28)(C) and the regulations thereunder as of a date that is no more than 12 months
before the relevant transaction to which the valuation is applied.

2.16. “Grant Date” means the effective date on which an Award is made to a Participant as set
forth in the applicable Phantom Stock Agreement.

2.17. “Participant” shall mean an Employee of the Company who has an Employment Agreement to
whom an Award is granted under this Plan.

2.18. “Payment Date” means the date established in Section 6.2 of the Plan.

2.19. “Performance Share Phantom Stock Agreement” or “Retention Phantom Stock Agreement”
(collectively referred to as “Phantom Stock Agreement”) means the agreement between the Company and
the Participant pursuant to which the Company authorizes an Award hereunder. Each Phantom Stock
Agreement entered into 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.

2.20. “Performance Share Phantom Stock” or “Retention Phantom Stock” (collectively referred to
as “Phantom Stock”) means a unit granted to a Participant that entitles the Participant to receive
a payment in cash equal to the Fair Market Value of a share of Common Stock on the date the
respective grants of Phantom Stock pay out.

2.21. “Plan” means the Alion Science and Technology Corporation Performance Shares and
Retention Phantom Stock Plan, as amended from time to time.

2.22. “Target Performance Share Award” means 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.

 

- 4 -

 

2.23. “Termination of Employment” means the severing of employment with the Company and its
Affiliates for any reason. A Termination of Employment will be deemed to have occurred if the
facts and circumstances indicate that the Company and Participant reasonably anticipate that no
further services will be performed after a certain date or that the level of bona fide services the
Participant will perform for the Company or any Affiliate after
such date (whether as an employee or as an independent contractor) will permanently decrease
to no more than the lesser of (a) 19 hours of bona fide services per week, or (b) fifty percent
(50%) of the average level of bona fide services performed (whether as an employee or an
independent contractor) over the immediately preceding 36-month period (or the full period of
services to the employer if the Participant has been providing services to the Company and its
Affiliates). 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 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.

2.24. “Valuation Date” shall mean a date as of which the Fair Market Value of Common Stock of
the Company is determined.

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;

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.

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.

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.

(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.

 

- 8 -

 

(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.

 

- 9 -

 

(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;

(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.

 

- 10 -

 

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.

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.

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, 2014, 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.

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.

11.3. Indemnification of Board and 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.

 

- 13 -

 

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.

IN WITNESS WHEREOF, the undersigned has caused this instrument to be executed as of November
13, 2007, and certifies that the foregoing Plan was duly adopted by the Board of the Company on
that date.

Exhibit 4.24

ALION SCIENCE AND TECHNOLOGY CORPORATION

BOARD OF DIRECTORS PHANTOM STOCK PLAN

The Alion Science and Technology Corporation Phantom Stock Plan (the “Plan”) was
established by Alion Science and Technology Corporation, a Delaware corporation (“Alion” or the
“Company”), effective as of October 1, 2005. The Plan is hereby amended and restated
effective January 1, 2007 to comply with final regulations under Code Section 409A; provided,
however, that any provision herein required to be effective as of an earlier date in order for the
Plan to comply with Code Section 409A shall be effective as of such earlier date.

ARTICLE I

PURPOSE

The purpose of the Plan is to benefit and advance the interests of the Company by attracting
and retaining directors, by rewarding them for their contributions to the financial success of the
Company and thereby motivating them to continue to make such contributions in the future, 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” shall mean 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. “Award” means a grant of Phantom Stock under this Plan.

2.3. “Board” means the Board of Directors of the Company.

2.4. “Cause” means that the Participant has (a) abandoned his position as a Director; (b)
engaged in willful misconduct deleterious to the interests of the Company, including but not
limited to engaging in or assisting a competing business enterprise without the consent of the
Board, making public statements disparaging of the Company or its personnel or customers, other
than truthful statements made in connection with a legal proceeding or governmental investigation,
or disclosing trade secrets or other confidential information of the Company in an unauthorized
manner; (c) been convicted of a felony crime; or (d) been indicted for a felony crime relating to
the Participant’s business conduct or morals, if the Board determines that the Participant’s
continuing service as a Director is deleterious to the interests of the Company. Whether a
Participant’s Termination of Service is the result of Cause shall be determined by the Board in its
sole discretion.

 

 

 

2.5. “Change in Control” shall mean and shall be deemed to have occurred as of the date of the
first to occur of the following events:

(a) any Person or Group acquires stock of the Alion that, together with stock held by
such Person or Group, constitutes more than fifty percent (50%) of the total Fair Market
Value or total voting power of the stock of Alion. However, if any Person or Group is
considered to own more than fifty percent (50%) of the total Fair Market Value or total
voting power of the stock of Alion, the acquisition of additional stock by the same Person
or Group is not considered to cause a Change in Control of Alion. An increase in the
percentage of stock owned by any Person or Group as a result of a transaction in which Alion
acquires its stock in exchange for property will be treated as an acquisition of stock for
purposes of this subsection. This subsection applies only when there is a transfer of stock
of Alion (or issuance of stock of Alion) and stock in Alion remains outstanding after the
transaction;

(b) any Person or Group acquires (or has acquired during the 12-month period ending on
the date of the most recent acquisition by such Person or Group) ownership of stock of Alion
possessing thirty percent (30%) or more of the total voting power of the stock of Alion;

(c) a majority of members of Alion’s Board is replaced during any 12-month period by
Directors whose appointment or election is not endorsed by a majority of the members of
Alion’s Board prior to the date of the appointment or election; or

(d) any Person or Group acquires (or has acquired during the 12-month period ending on
the date of the most recent acquisition by such Person or Group) assets from Alion that have
a total gross fair market value equal to or more than forty percent (40%) of the total gross
fair market value of all of the assets of Alion immediately prior to such acquisition or
acquisitions. For this purpose, gross fair market value means the value of the assets of
Alion, or the value of the assets being disposed of, determined without regard to any
liabilities associated with such assets. However, no Change in Control shall be deemed to
occur under this subsection (d) as a result of a transfer to:

(1) A shareholder of Alion (immediately before the asset transfer) in exchange
for or with respect to its stock;

(2) An entity, fifty percent (50%) or more of the total value or voting power
of which is owned, directly or indirectly, by Alion;

(3) A Person or Group that owns, directly or indirectly, fifty percent (50%) or
more of the total value or voting power of all the outstanding stock of Alion; or

(4) An entity, at least fifty percent (50%) of the total value or voting power
of which is owned, directly or indirectly, by a person described in clause (3)
above.

limited liability company, joint venture, trust, unincorporated organization or government or
agency, instrumentality or political subdivision thereof (other than an employee benefit trust
established
or maintained for the benefit of employees of the Corporation). The term “Group”
shall have the meaning set forth in Rule 13d-5 of the Securities Exchange Commission (“SEC”),
modified to the extent necessary to comply with Treasury Regulation Section 1.409A-3(i)(5), or any
successor thereto in effect at the time a determination of whether a Change in Control has occurred
is being made. If any one Person, or Persons acting as a Group, is considered to effectively
control the Corporation as described in subsections (b) or (c) above, the acquisition of additional
control by the same Person or Persons is not considered to cause a Change in Control.

2.6. “Code” means the Internal Revenue Code of 1986, as amended and any successor Code, and
related rules, regulations and interpretations.

2.7. “Common Stock” means the voting common stock, $0.01 par value per share, of the Company,
subject to adjustments pursuant to the Plan.

2.8. “Company” means Alion Science and Technology Corporation, a Delaware corporation.

2.9. “Director” means a member of the Board of Directors of the Company who is not also an
employee of the Company on the Grant Date.

2.10. “Disability” means that the Participant (a) is unable to engage in any substantial
gainful activity by reason of any medically determinable physical or mental impairment that can be
expected to result in death or to last for a continuous period of not less than 12 months; or (b)
has been determined to be totally disabled by the Social Security Administration.

2.11. “Fair Market Value” on any given date means the value of one share of Common Stock as
determined by the Administrative Committee in its sole discretion, based upon the most recent
valuation of the Common Stock made by an independent appraisal that meets the requirements of Code
Section 401(a)(28)(C) and the regulations thereunder as of a date that is no more than 12 months

forth in the applicable Phantom Stock Agreement.

2.13. “Participant” means a member of the Board of the Company to whom an Award is granted
under this Plan.

receive a payment in cash equal to the Fair Market Value of a share of Common Stock as of the
Surrender Date.

2.15. “Phantom Stock Agreement” means the agreement between the Company and the Participant
pursuant to which the Company makes an Award hereunder. Each Phantom Stock Agreement shall
incorporate the terms of this Plan and shall contain such further terms and conditions consistent

2.16. “Plan” means the Alion Science and Technology Corporation Phantom Stock Plan, as amended
from time to time.

2.17. “Plan Year” means the fiscal year of the Company.

2.18. “Surrender Date” means the date as of which a Participant surrenders Phantom Stock
shares pursuant to Section 7.1 below.

2.19. “Termination of Service” means termination of the Participant’s status as a Director of
the Company and, if the Director is otherwise an independent contractor of the Company, complete
and good-faith termination of of any such contractual relationship. If the Director is also an
employee of the Company or any Affiliate (as such term is defined in the Alion Executive Deferrd
Compensation Plan), the services provided as an employee are not taken into account in determining
whether the Director has incurred a Termination of Service hereunder to the extent this Plan is not
aggregated for purposes of Treasury Regulation Section 1.409-1(h)(5) with any deferred compensation
plan in which he or she participates as an employee.

2.20. “Valuation Date” means a date as of which the Fair Market Value of Common Stock of the
Company is determined.

2.21. “Year of Vesting Service” means a complete year of the Participant’s service as a
Director, beginning with the Grant Date of the applicable Award and each anniversary of such date
after the Grant Date.

ARTICLE III

ADMINISTRATION

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 Administrative Committee
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 majority vote of those members entitled to vote.
Additionally, any acts reduced to writing and approved in writing by all of the members of the
Administrative Committee hereunder shall be valid acts of the Administrative Committee. Members of
the 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
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.
Notwithstanding the foregoing, a member of the Committee
will not be deemed as acting upon the granting of an Award to himself or herself under the
preceding sentence if the matter under consideration applies equally to all Participants.

 

- 4 -

 

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 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) accelerate or otherwise change the time in which an Award may be vested, and to
waive or accelerate the lapse, in whole or in part, of any restriction or condition with
respect to such Award, except that the date of payment of an Award may not be accelerated in
a manner inconsistent with Code Section 409A; or

(f) 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.

or Administrative Committee hereunder shall be liable for any action taken or decision made in good
faith relating to the Plan or any Award.

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

Company, its stockholders, any Participants in the Plan and any employee, officer or Director of
the Company, and their respective successors in interest.

ARTICLE IV

PARTICIPATION

Each individual who is a Director and who is not also an employee of the Company as of a Grant
Date is eligible to participate in the Plan while he or she is a member of the Board of Directors.

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 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 Awards. Except as otherwise provided in Section 5.4, an Award shall be
made to each eligible Director as of the date of the first general Board of Directors meeting of
each Plan Year within the term of this Plan (each, a “Grant Date”). In addition, each
individual who becomes a Director during a Plan Year within the term of this Plan after the first
general meeting of the Board for such Plan Year shall be eligible for an Award effective as of the
date he or she becomes a Director (also a “Grant Date”). The Compensation Committee of the Board
of Directors shall have discretion to determine the amount of Phantom Stock to be awarded for any
Plan Year; provided, however, that, except as otherwise provided in Section 5.4, each Director as
of the date of the first general meeting of the Board during the Plan Year to which the Award
relates shall receive the same level of Award. Unless and until the Compensation Committee
determines otherwise, the number of units of Phantom Stock which shall be awarded to a Director for
a Plan Year shall be the number determined by dividing thirty-five thousand dollars ($35,000) by
the Fair Market Value (determined as of the Valuation Date corresponding with or immediately
preceding such Grant Date) of a share of Common Stock on the Grant Date, rounded to the next
highest round number; provided, however, that an Award made to an individual who becomes a Director
after the first general Board of Directors meeting for the applicable Plan Year shall be prorated
to reflect the number of full and partial calendar months remaining in such Plan Year from the date
of the Director’s election. A Participant who incurs a Termination of Service or is not a Director
for any reason as of the close of business on the Grant Date shall not be eligible for an Award.

5.3. Phantom Stock Agreement. The grant of an Award 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.

 

- 6 -

 

5.4. 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 (“ESOP”) 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 Participant shall have no right to receive payment for any share of
Phantom Stock upon the applicable Surrender Date, as described below, unless and until such Phantom
Stock Award has become vested. Unless otherwise determined by the Administrative Committee in a
Participant’s Phantom Stock Agreement, Awards shall vest in accordance with the following schedule:

	 	 	 	 	 
	Service from the Grant Date	 	Amount Vested	 
	 
	 	 	 	 
	One Year of Vesting Service for Awards granted prior to
November 1, 2007, or one Year and 31 days of Vesting Service
for Awards granted on or after November 1, 2007
	 	 	33	%
	Two Years of Vesting Service
	 	 	66	%
	Three Years of Vesting Service
	 	 	100	%

6.2. Termination and Forfeiture of Awards. If a Participant incurs a Termination of
Service 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) Death or Disability. If the Participant’s Termination of Service is due to
death or Disability, any outstanding Awards at the time of such Termination of Service shall
immediately become 100% vested.

(b) Change in Control. If the Participant incurs a Termination of Service 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 Service shall immediately
become 100% vested.

 

- 7 -

 

(c) Failure to be Reelected. If the Participant fails to be reelected as a
Director for any reason other than Cause, such Director shall continue to vest in accordance
with the above schedule, without regard to such Termination of Service. Notwithstanding the
foregoing, Awards issued on or after November 1, 2007, shall not become vested under this
Section 6.2(c), if a Participant fails to be reelected as a Director for any reason within
the first one year and thirty one days after the Grant Date of such Award.

(d) Disqualified Persons. If Participant is or becomes a Disqualified Person
as described in Section 5.4 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. Surrender Date. The Administrative Committee may, in its discretion, permit a
Participant to elect whether the Surrender Date with respect to an Award shall occur (a) with
respect to any portion of an Award which has become vested under Section 6.1, 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 Service. Notwithstanding
the foregoing or any contrary election by the Participant, if a Participant incurs a Termination of
Service but continues to vest under Section 6.2(c), the Surrender Date of any portion of a
then-outstanding Award that has vested prior to the Participant’s Termination of Service shall be
the date of such Termination of Service, and the Surrender Date of any portion of the Award that
becomes vested after the Participant’s Termination of Service shall be the date on which such
portion of the Award becomes vested. Any such election shall be made in a writing acceptable to
the Administrative Committee and filed with the Administrative Committee as of a date specified by
the Administrative Committee which is within 30 days after the Award Grant Date; provided, however,
that an election by a Participant who first becomes a Director on the Grant Date shall be made
within 30 days of the Grant Date (provided that such Director was not eligible to participate in
this or any similar non-qualified deferred compensation plan of the Company required to be
aggregated with this Plan under Treasury Regulation Section 1.409-1(h)(5) during the preceding 24
month period). 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 (except as
provided above with respect to Section 6.2(c)). 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 Federal government ethics agreement or to avoid violation of applicable
Federal, state, local or foreign ethics law or conflicts of interest law;

 

- 8 -

 

(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) 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.

7.2. Amount of Payment. A Participant shall be entitled to a cash payment upon
surrender 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.

7.3. Time of Payment. Except as provided in Section 7.4, the Company shall make
payment of the amount receivable upon the exercise of an Award by the delivery of cash in a lump
sum as soon as practicable, but in any event within ninety (90) days, after the Surrender Date.
Notwithstanding the foregoing, 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, a payment otherwise
required to be made under the terms of the Plan may be delayed 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 the Deduction Limitation: The Company reasonably
anticipates that such payment would otherwise violate Code Section 162(m);

(b) Violation of Law: The Administrator reasonably determines that making the
payment will violate Federal securities or other applicable laws; or

(c) Other Permitted Event: Upon such other events and conditions as the
Commissioner of Internal Revenue shall prescribe in generally applicable guidance.

 

- 9 -

 

7.4. Election to Defer Payments. If a Participant has elected, or is deemed to have
elected, as the Surrender Date of an Award under Section 7.1 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 Alion Director
Deferred Compensation Plan (the “Deferred Compensation Plan”), provided that he or she has
not incurred a Termination of Service 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; provided, however, that an election to defer the receipt of a payment under this
Section 7.4 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 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 Service, Change in Control, death or Disability) earlier than
five years after the Surrender 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 7.3 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 Article V of the Deferred Compensation
Plan. This Section 7.4 shall not apply to amounts withheld under Section 7.7.

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

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

TRANSACTIONS

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.

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

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 may terminate
the Participant’s Phantom Stock Award by notice to him or her, and it shall thereupon become null

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.

IN WITNESS WHEREOF, the undersigned has caused this instrument to be executed as of November
13, 2007, and certifies that the foregoing Plan, as amended and restated herein, was duly adopted
by the Board of the Company on that date.
