SECTION 3.        EXECUTIVE'S DUTIES AND OBLIGATIONS.

        3.1     Duties. During the Period of Employment, Executive agrees to (i)
serve as President & Chief Executive Officer of the Company and to perform such

efforts toward the fulfillment and execution, including performance criteria, of

good faith determination of the Board of Directors, interfere in any material
respect with the performance of his duties hereunder.

SECTION 4.        COMPENSATION

        4.1     Base Salary. For the services to be rendered by Executive
hereunder during the Period of Employment, the Company shall pay Executive a
base salary ("Salary") in the amount stated in Exhibit B, such Salary to be
payable in bi-weekly installments. From time to time, the Company may conduct a
review of Executive's Salary, giving attention to all pertinent factors
including, without limitation, the performance and financial condition of the
Company and the performance of Executive; and the Company shall, following such
review, determine any adjustments in Executive's Salary.

        4.2     Incentive Compensation. Provided that Executive has remained
continuously employed by the Company or an Affiliate of the Company from the
date hereof through the end of each fiscal year of the Company during the Period
of Employment, Executive shall be eligible to receive the performance-based
incentive compensation initially specified in Exhibit B and, thereafter, as
established by the Company at the same time and in the same manner as the
Company shall establish performance objectives for its senior executives, at all
times to be administered by the Company using its sound business discretion.

SECTION 5.        STOCK PURCHASE AND STOCK OPTIONS.

        The Company and Executive have previously executed: (a) a Stock Purchase
Agreement providing for the purchase by Executive of shares of Class B common
stock of the Company and a loan from the Company for that purpose on the terms
and conditions specified therein; and (b) several Stock Option Award Agreements
providing for the grant to Executive of options to acquire shares of Class B

Agreements are incorporated by reference and made a part hereof.

senior executive of the Company, have the right to become a participant or
beneficiary under or pursuant to any and all Employment Benefit Plans now in
force or later adopted for which Executive is eligible under the respective
provisions thereof. Nothing in this Agreement shall require the Company or any
Affiliate of the Company to adopt any Employee Benefit Plan and nothing in this
Agreement shall prevent the Company or any Affiliate of the Company from
amending, modifying or terminating any or all Employee Benefit Plans now or
hereafter in force. Executive's rights under any Employee Benefit Plans now in

SECTION 7.        NON-COMPETITION AND CONFIDENTIALITY

        As additional consideration for the employment of Executive by the
Company and in order to ensure the preservation and protection of Company good
will, trade secrets, and confidential information entrusted to Executive,
Executive agrees, during the Period of Employment and for a period of six (6)
months after Executive's voluntary termination of employment from the Company or
termination for Cause ("Six-Month Term"), to forbear from engaging in any of the
activities specifically enumerated in subparagraphs 7.1 through 7.6 below,
without first obtaining the written consent of Company. More specifically:

        7.1     Executive agrees to forbear during the Six-Month Term from
                serving as an officer or director of any Competing Enterprise,
                except serving as a director of a corporation with a class of
                equity securities registered under Section 12(b) or Section
                12(g) of the Securities Exchange Act of 1934;

        7.2     Executive agrees to forbear during the Six-Month Term from

                any Competing Enterprise;

        7.3     Executive agrees to forbear during the Six-Month Term from
                owning, directly or indirectly, any equity or beneficial
                interest in any Competing Enterprise, except ownership of less
                than five percent (5%) of the outstanding voting interests of an
                Entity with a class of equity interests registered under Section
                12(b) or Section 12(g) of the Securities Exchange Act of 1934;

        7.4     To the extent that Executive's duties and assignments with the
                Company or any Affiliate of the Company involved confidential
                applied research, design, or development of any product,
                technology, software, process, or service of the Company or any
                Affiliate of the Company, Executive agrees to forbear from any
                employment, assistance, consultation or other active
                participation with any Competing Enterprise during the Six-Month
                Term that would involve any applied research, design, or
                development of any similar or competing product, technology,
                software, process, or service for a Competing Enterprise;

        7.5     To the extent that Executive's duties and assignments with the
                Company or any Affiliate of the Company involved confidential
                strategic planning, business partnering, business development,
                marketing, or bid/proposal activities, Executive agrees to
                forbear from any employment, assistance, consultation or other
                active participation with any Competing Enterprise during the
                Six-Month Term that would involve or directly or indirectly
                assist (including "behind the scenes") any solicitation,
                business development, marketing, or bid/proposal activities with
                respect to any present or foreseeable prospective customer or
                business partner of the Company or any Affiliate of the Company
                as of the date of Executive's termination of employment; and

        7.6     Executive agrees to forbear, during the Six-Month Term and for
                an additional six (6) months thereafter, from engaging in, or
                directly or indirectly assisting any



                                     - 3 -
<PAGE>


                Competing Enterprise in, any activity to hire away any
                then-current employee, officer, or agent of the Company or any
                Affiliate of the Company.

        7.7     Executive further agrees that: (i) the aforementioned
                restrictions are reasonable in both scope and duration, in view
                of the nature and geographic reach of the business of the
                Company and its Affiliates, the state of the technical and
                commercial development of the products and services of the
                Company and its Affiliates, the nature of the work that
                Executive performs for the Company or any Affiliate of the
                Company, Executive's knowledge of the business of the Company
                and its Affiliates, and the Company's interests in preserving
                and protecting its goodwill, trade secrets, and confidential
                information; (ii) if any provision of this Section 7 shall be
                held or deemed to be invalid, inoperative, or unenforceable for
                any reason, the remaining provisions of this Section 7 shall be
                reformed and construed as if such invalid, inoperative, or
                unenforceable provision had never been contained herein, and
                such invalid, inoperative, or unenforceable provision shall be
                reformed so that it would be valid, operative, and enforceable
                to the maximum extent permitted; (iii) money damages would not
                be a sufficient remedy for any breach of this Section 7, and the
                Company shall be entitled to enforce the provisions of this
                Section 7 by specific performance and injunctive relief as
                remedies for such breach or any threatened breach and any such
                remedies shall not be deemed the exclusive remedies for a breach
                of this Section 7 but shall be in addition to all other remedies
                available at law or in equity against Executive and any other
                party involved in such breach; and (iv) the obligations of
                Executive under this Section 7 are in addition to all other
                obligations of Executive, by contract and under law, to protect
                and refrain from using or disclosing to others the trade secrets
                and confidential information of the Company and its Affiliates.
                Executive waives any requirement for the Company to post a bond
                or provide any other security in connection with its pursuit of
                any remedies hereunder.

SECTION 8.        INFORMATION DISCLOSED REMAINS PROPERTY OF THE COMPANY

        All ideas, concepts, information, and written material disclosed to
Executive by the Company or any Affiliate of the Company, or acquired from a
customer or prospective customer of the Company or any Affiliate of the Company,
are and shall remain the sole and exclusive property and proprietary information
of the Company, such Affiliate of the Company or such customers, and are
disclosed in confidence by the Company or such Affiliate of the Company or
permitted to be acquired from such customers in reliance on Executive's
agreement to maintain them in confidence and not to use or disclose them to any
other Person except in furtherance of the business of the Company or any
Affiliate of the Company. The ideas, concepts, information, and written material
covered by this Agreement do not include such ideas, concepts, information or
written material which (i) becomes or has been generally available to the public
other than as a result of a disclosure by Executive or any other Person bound by
a confidentiality agreement with the Company or any Affiliate of the Company,
(ii) was available to Executive on a nonconfidential basis prior to its
disclosure to Executive by the Company or any Affiliate of the Company, or (iii)
becomes available to Executive on a nonconfidential basis from a source other
than the Company or any Affiliate of the Company; provided, however, that such
source is not bound by a confidentiality agreement with the Company or any
Affiliate of the Company.

SECTION 9.        RETURN OF MATERIAL

        Executive agrees that, at any time upon the request of the Company and
in any event upon termination of employment, Executive shall turn over to the
Company, and not retain any copies of, all documents, disks or other computer
media, or other material in his possession or under his control that (i) may
contain or be derived from ideas, concepts, inventions, discoveries,
improvements, creations, or trade secrets and other proprietary and confidential
information as set forth in Section 7 and Section 8 above, or (ii) are connected
with or derived from Executive's services to the Company.

SECTION 10.       ENFORCEMENT OF COVENANTS.

        It is expressly understood and agreed by Executive that the covenants
contained in Section 7, Section 8 and Section 9 of this Agreement represent a
reasonable and necessary protection of the legitimate interests of the Company
and that Executive's failure to observe and comply with his covenants and
agreements therein may cause irreparable harm to the Company. It is expressly
understood and agreed by Executive that it is and will continue to be difficult
to ascertain the nature, scope and extent of the harm resulting from breach of
these covenants and that a remedy at law for such breach by Executive will be
inadequate. Accordingly, it is the intention of the parties that, in addition to
any other rights and remedies which the Company may have in the event of any
breach of this Agreement, the Company shall be entitled, and is authorized by
Executive, to demand and obtain specific performance, including without
limitation all appropriate injunctive and other equitable relief against
Executive in order to enforce against Executive, or to prevent any breach or any
threatened breach by Executive of the covenants and agreements contained in this
Agreement. Executive agrees to pay all costs and reasonable attorneys' fees
incurred by the Company to enforce its rights under this Agreement, if and to
the extent the Company prevails.

SECTION 11.       INDEMNIFICATION

        With respect to his services during the Period of Employment as a
director, officer, employee, or agent of the Company or any Affiliate of the
Company, the Company shall indemnify Executive, whether during or after the
Period of Employment, to the fullest extent authorized under the Delaware
General Corporation Law. If requested by Executive and subject to receipt by the
Company of an undertaking by or on behalf of Executive to repay such expenses if
it is ultimately determined that Executive is not entitled to be indemnified by
the Company as authorized in this Section, the Company shall advance to
Executive all reasonable expenses incurred by Executive in connection with any
claim for indemnification hereunder to the fullest extent permitted by law (or,
if applicable, reimburse Executive for any and all reasonable expenses incurred
by Executive and previously paid by Executive) within ten (10) business days
after such request. The Company shall be obligated from time to time at the
request of Executive to make or pay such advancement or reimbursement of
expenses in advance of the final disposition or conclusion of any action, suit
or proceeding. Notwithstanding anything to the contrary in this Agreement, the
Company's obligations under this Section shall never cease or terminate.

                12.7.1  If this Agreement is terminated by the Company pursuant

        Company shall have no obligation to pay to Executive the Salary or any
        other compensation or benefits provided under this Agreement for any
        period after the date of such termination; including any bonus for the

        Company shall (a) pay Executive, within thirty (30) days of the date of
        such termination, all Salary and other compensation and vested benefits



                                     - 6 -

        payments in amounts and forms determined in accordance with the
        Company's severance policy for senior corporate executives then in

        notice to the Company within sixty (60) days of such termination, the
        Company shall repurchase all stock and other direct and indirect
        ownership interests in the Company held by Executive, at the Fair Market
        Value per Share (as that term is defined in the Stock Purchase
        Agreement) determined as of the date of such termination; provided,
        however, that if the Company is restricted by applicable law or any
        agreement to which the Company is a party from repurchasing all or any
        part of such ownership interests, then the Company's obligation to
        repurchase such interests shall be deferred until such time as such
        restrictions are no longer in effect.

                12.7.4  If this Agreement is terminated pursuant to Section
        12.6, then, in addition to the Salary earned by Executive prior to the
        date of such termination, the Company shall pay Executive, within thirty
        (30) days of the date of such termination: (a) all Salary and other
        compensation and vested benefits accrued but unpaid as of the date of
        termination, (b) an allocable portion of any incentive compensation that
        the Company, using its reasonable business discretion, determines would
        have been earned had Executive remained employed through the end of the
        year in which such termination occurs, plus one full year, determined
        pro rata based on target bonus, and (c) a lump-sum severance payment in
        the amount of three times Executive's annual Salary then in effect. In
        addition: (d) the Company shall provide continuation of medical
        benefits, or a cash equivalent, for a period of three years or until
        Executive obtains new employment, whichever is the shorter period, (e)
        the Company shall pay for outplacement services for Executive for a
        period of one year following the date of such termination or until
        Executive obtains a comparable position, whichever occurs first, and (f)
        on the date of such termination, all rights of the Company under the
        Stock Purchase Agreement to repurchase the ownership interests of
        Executive in the Company at less than Fair Market Value (as such terms
        is defined in the Stock Purchase Agreement) shall expire and all
        unvested options to acquire stock of the Company then outstanding and
        held by Executive shall fully vest.

                12.7.5  In the event that the total payments to which Executive
        becomes entitled to receive following termination of employment under
        this Agreement (excluding accrued but unpaid Salary as of such date), or
        under any other agreement with or plan of the Company (in the aggregate,
        the "Total Payments"), become or are subject to the tax (the "Excise
        Tax") imposed by Section 4999 of the Code (or any similar tax that may
        hereafter be imposed), the Company shall pay to Executive in cash an
        additional amount (the "Gross-Up Payment") such that the net amount
        retained by Executive after deduction of any Excise Tax upon the Total
        Payments and any federal, state and local income tax and Excise Tax upon
        the Gross-Up Payment provided for by this Section 12.7.5 (including FICA
        and FUTA), shall be equal to the Total Payments. Such payment shall be
        made by the Company to Executive as soon as practical following the
        effective date of termination, but in no event beyond thirty (30) days
        from such date.

        12.8    Obligations Surviving Termination. Upon the termination of this
Agreement, all of the Company's obligations under this Agreement shall cease,
except for (i) the obligation to

pay the amounts provided in Section 12.7, (ii) any obligations under any
Employee Benefit Plans that by their terms are payable after the date of such
termination and (iii) the obligation to provide indemnification under Section
11. Upon the termination of this Agreement, all of Executive's obligations under
this Agreement shall cease except for the obligations set forth in Section 7,
Section 8, Section 9 and Section 10, which shall survive. The termination of
this Agreement shall not increase or decrease Executive's rights under any
Employee Benefit Plan.

                                   MEMORANDUM

DATE:     January 30, 2002
TO:       David Langstaff
FROM:     Joe Allen
RE:       2002 Compensation Plan
--------------------------------------------------------------------------------

COMPENSATION

Your annual base salary as of January 1, 2002 is $450,000. Your target bonus
for 2002 is $337,500. Your actual bonus will be based on the performance
metrics described below, the ultimate size of the incentive compensation ("IC")
pool, your performance, and on the terms of the plan approved by the Board of
Directors for the year.

SIZING AND FUNDING THE CORPORATE IC POOL

The actual corporate IC pool will be created (i.e., funded) based upon three
factors reflecting our 2002 financial performance:

     1.   Meeting our budgeted consolidated operating profit (EBIT) targets;
     2.   The absolute growth in consolidated operating profit from 2001 to
          2002; and
     3.   The absolute growth in consolidated revenues from 2001 to 2002.

Specifically, the actual IC pool will be determined by adding the following
three percentages, and multiplying that sum by the budgeted incentive pool:

     1.   40% multiplied by: the actual rate of growth in operating profit
          divided by the budgeted rate of growth in operating profit, subject to
          a ceiling of 40%;
     2.   Three (3) times the actual percentage growth in operating profit from
          2001 to 2002; and
     3.   Two and one-half (2-1/2) times the actual percentage growth in
          revenues from 2001 to 2002.

Note that there is no ceiling on the amounts calculated in points 2 and 3,
above.

INDIVIDUAL ALLOCATION METHODOLOGY

Given that the IC pool will be funded based on financial performance (as
described above) and our ability to accrue IC funds within our rate structure,
the ultimate size of the pool will be determined by actual financial
performance at year-end. Regardless as to the ultimate size of the IC pool at
year end, it will be segmented into two components:

          Participation Segment (25%)
          Discretionary Segment (75%)
<PAGE>
The participation segment reflects the fact that, while individual performance
is important, we succeed or fail as a team. Twenty-five percent of the IC pool
will be set aside and shared among the participants of the incentive
compensation pool on a pro-rata basis based on base salary. This component is
intended to underscore the fact that we must all assume responsibility for the
overall performance of the company, support each other wherever possible, and
work together in order to achieve success and therefore, maximize the size of
the incentive compensation pool.

The discretionary segment will consist of seventy-five percent of the total IC
pool, and will be based on an assessment of your contribution to the financial
performance of the company, any specific financial metrics discussed with you,
and your performance against your 2002 performance priorities (as previously
assigned).

Please recognize that, while the funding of the IC pool is calculated based on
performance, it is subject to final determination based on what can be accrued
within our rate structure. We may, on occasion, find that the funding
calculations suggest an IC pool that is greater than what we can accrue, due to
higher than expected indirect costs in other areas. To state the obvious, we
all share an objective of keeping our indirect costs within reason and budget.

The allocation of the IC pool to each individual will be done according to the
guidelines presented above, but nevertheless will remain subjective, with
judgments made that are not formulaic. The primary purpose of the 'Target
Bonus' amount identified for you is to determine your percentage of the IC
pool, assuming all performance targets (both corporate and individual) are
exactly met.

GENERAL RULES

Payment will be made to you during the first quarter of 2003, after
substantially final determination of the 2002 financial performance of the
company. Final year-end performance numbers may be adjusted by the CEO and the
Board of Directors, in their sole discretion.

All bonuses, despite metrics, remain subject to discretionary review,
adjustment, and approval of the CEO and the Veridian Board of Directors. In
particular, please note that:

     1.   An Executive Bonus may be reduced or eliminated for serious violations
          by the participant of Company policy, government laws or regulations,
          or as disciplinary action within the Company's Self-Governance
          program. Such actions require the approval of the CEO and the General
          Counsel.

     2.   The Plan focuses on the operating performance of the business. In the
          event significant consolidation or acquisition/divestiture activities
          occur during the Plan year which were not figured into the performance
          target, payments otherwise available under the Plan will be reviewed
          and may be altered with the approval of the CEO and the Board of
          Directors.

     3.   If your employment terminates during 2002 or before final calculation
          of bonus payments in 2003, for any reason other than a Change of
          Control (as defined in the Veridian Corporation 2000 Stock Incentive
          Plan) you will not be entitled to any payment under this Plan.

     4.   All bonuses are subject to funds having been accrued during 2002 to
          pay them. In the event that the bonus pool is insufficient to meet
          bonus obligations, then bonuses shall be adjusted on a pro-rata or
