      “ Chairman/CEO ”)
      for a
      period to be agreed upon by the Executive and the Compensation Committee of
      the
      Board of Directors (the “ Compensation

      however ,
      that

      responsibilities and obligations pursuant to this Agreement. These restrictions
      shall not apply to the Executive during the Chairman Only Period. The Executive
      shall use his best efforts to promote the interests and welfare of the

(a)  Base
      Compensation .

      a base salary at the rate of $300,000 per year, as adjusted from time to time
      with the approval of the Compensation Committee (“ CEO

      The
      Executive’s base salary during the Chairman Only Period shall be at a reduced

      Base Compensation ”).

      the CEO Period in an amount up to 65% of the CEO Base Compensation. The
      Incentive Compensation payable for each performance period (which shall not
      be
      less than twelve (12) months) shall be contingent on and based on corporate
      and
      individual performance criteria agreed to between the Executive and the
      Compensation Committee from time to time. At or before the commencement of
      the
      Chairman Only Period, the Executive and the Compensation Committee will agree
      on
      the extent, if any, to which the Executive shall be entitled to Incentive
      Compensation during the Chairman Only Period. The target amount payable as

(b)  In
      the
      event the Corporation terminates the Executive’s employment without Cause or the
      Executive terminates his employment for Good Reason, then, in addition to the
      benefits provided for under Sections 6(a)(i) and 6(a)(ii) and subject to the
      provisions of Section 8, the Corporation shall pay to the Executive (i) a
      severance benefit equal to the Executive’s then applicable CEO Base Compensation

      the
      case may be, the “ Applicable
      Severance Period ”),
      (ii)

      calculate the amount of Incentive Compensation the Executive would have received

      Executive would have received had the Executive remained employed by the
      Corporation for the entire applicable calendar year is in excess of 50% of
      the
      Incentive Compensation Target for that year (the “ Overage
      Amount ”),

      Overage Amount shall be payable in respect of years following the year in which
      the Executive’s employment with the Corporation is terminated.

      all
      unvested stock options and any other equity-based compensation arrangements
      shall be terminated and all vested stock options shall be exercisable in
      accordance with the applicable award agreement.




(e)  For
      purposes of this Agreement, the Executive shall be considered to have

      employment voluntarily by Executive, by the Corporation for Cause, or under
      the
      circumstances described in Section 8 hereof), (i) the responsibilities of the
      Executive are substantially reduced or altered, (ii) the Executive’s CEO Base

      days after actual receipt written notice of the Executive’s assertion of Good
      Reason to cure the basis for such assertion, and, in the event of cure (or
      the
      commencement of steps reasonably designed to result in prompt cure), the
      assertion of Good Reason shall be null and void.


5




(f)  For
      purposes of this Agreement, the Corporation shall have “ Cause ”
to
      terminate the Executive’s employment hereunder upon (i) the continued, willful
      and deliberate failure of the Executive to perform his duties in a manner
      substantially consistent with the manner prescribed by the Board (other than
      any
      such failure resulting from his incapacity due to physical or mental illness),
      (ii) the engaging by the Executive in misconduct materially and demonstrably
      injurious to the Corporation, (iii) the conviction of the Executive of
      commission of a felony, whether or not such felony was committed in connection
      with the Corporation’s business, (iv) the circumstances described in Section 8
      hereof, in which case the provisions of Section 8 shall govern the rights and
      obligations of the parties, or (v) during the Chairman Only Period (but prior

      in clauses (i) or (ii), the Executive shall have a period of thirty (30)
      business days after actual receipt written notice of the Corporation’s assertion
      of Cause to cure the basis for such assertion, and, in the event of cure (or
      the
      commencement of steps reasonably designed to result in prompt cure), the
      assertion of Cause shall be null and void.




(g)  Notwithstanding
      any other provision hereof, the Executive shall not be entitled to receive
      any
      payment under Section 6 or 7 of this Agreement that is treated as “deferred
      compensation” within the meaning of Section 409A of the Code and the regulations
      thereunder prior to the time such payment is permitted to be made under Section
      409A(a)(2)(B) of the Code.

      the level of health insurance then maintained by the Executive (including

      to the expiration or termination of the Employment Period, the Executive shall
      be unable to perform his duties by reason of disability or impairment of health
      for at least six consecutive calendar months, the Corporation shall have the
      right to terminate the Executive’s employment on account of disability by giving
      written notice to the Executive to that effect, but only if at the time such
      notice is given such disability or impairment is still continuing. In the event
      of a dispute as to whether the Executive is disabled within the meaning of
      this
      Section 8(a), either party may from time to time request a medical examination
      of the Executive by a doctor selected by the Corporation, and the written
      medical opinion of such doctor shall be conclusive and binding upon the parties
      as to whether the Executive has become disabled and the date when such
      disability arose. The cost of any such medical examination shall be borne by
      the
      Corporation. If the Corporation terminates the Executive’s employment on account
      of disability, then, in addition to the benefits provided for under Sections
      6(a)(i) and 6(a)(ii), all unvested stock options and any other equity-based
      compensation arrangements shall be terminated, and all vested stock options
      shall be exercisable in accordance with the terms of the applicable award
      agreement.


7




(b)  If,
      prior
      to the expiration or termination of the Employment Period, the Executive shall
      die, then, in addition to the benefits provided for under Sections 6(a)(i)
      and
      6(a)(ii), the Employment Period shall terminate without further notice. In
      such
      an event, all unvested stock options and any other equity-based compensation
      arrangements shall be terminated, and all vested stock options shall be
      exercisable in accordance with the terms of the applicable award agreement.




(c)  Nothing
      contained in this Section 8 shall impair or otherwise affect any rights and
      interests of the Executive under any insurance arrangements, death benefit
      plan
      or other compensation plan or arrangement of the Corporation which may be
      adopted by the Board.




9.  Non-Competition/Non-Solicitation .




(a)  Non-Competition.  The
      Executive agrees that for a period commencing on the Effective Date and ending
      at the end of the Applicable Severance Period (the “ Non-Competition
      Period ”),
      the
      Executive will not, except as otherwise provided herein, engage or participate,
      directly or indirectly, as principal, agent, officer, employee, employer or
      consultant or in any other comparable capacity, in the conduct or management
      of,
      any business which is competitive with any business conducted by the
      Corporation. For the purpose of this Agreement, a business shall be considered
      to be competitive with the business of the Corporation only if such business
      is
      engaged in providing services similar to (i) any service currently provided
      by
      the Corporation or provided by the Corporation during the Employment Period;
      (ii) any service which in the ordinary course of business during the
      Non-Competition Period evolves from or results from enhancements to the services
      provided by the Corporation as of the Effective Date or during the
      Non-Competition; or (iii) any future service of the Corporation as to which
      the
      Executive materially and substantially participated in the design or
      enhancement. Nothing in this Section 9(a) shall be interpreted to prohibit
      the
      Executive from continuing to serve as a non-employee member of the board of
      directors of services companies that may compete with the Corporation or, during
      the Chairman Only Period, as the non-executive chairman of the board of such
      companies.




(b)  Non-Solicitation
      of Employees .
      During
      the Non-Competition Period, the Executive will not (for the Executive’s own
      benefit or for the benefit of any person or entity other than the Corporation)
      solicit, or assist any person or entity other than the Corporation to solicit,
      any officer, director, executive or employee of the Corporation or its
      affiliates to leave his or her employment.


8




(c)  Reasonableness .
      The
      Executive acknowledges that (i) the markets served by the Corporation are
      national and are not dependent on the geographic location of executive personnel
      or the businesses by which they are employed, (ii) the length of the
      Non-Competition Period is related to the length of the Employment Period and
      the
      Corporation’s agreement to provide severance benefits as set forth in Sections 6
      or 7, above, that, under certain circumstances, will provide additional
      compensation to the Executive upon the termination of the Executive’s
      employment; and (iii) the above covenants are reasonable on their face, and
      the
      parties expressly agree that such restrictions have been designed to be
      reasonable and no greater than is required for the protection of the
      Corporation.




(d)  Investments .
      Nothing
      in this Agreement shall be deemed to prohibit the Executive from owning equity
      or debt investments in any corporation, partnership or other entity which is
      competitive with the Corporation, provided that
      such investments (i) are passive investments and constitute five percent (5%)
      or
      less of the outstanding equity securities of such an entity the equity
      securities of which are traded on a national securities exchange or other public
      market, or (ii) are approved by the Compensation Committee.




10.  Waiver .
      The
      waiver of the breach of any term or provision of this Agreement shall not
      operate as or be construed to be a waiver of any other or subsequent breach
      of
      this Agreement. Failure by the Executive or the Corporation to insist upon
      strict compliance with any provision of this Agreement or to assert any right
      the Executive or the Corporation may have hereunder, including, without
      limitation, the right of the Executive to terminate employment for Good Reason,
      shall not be deemed to be a waiver of such provision or right or of any other
      provision or rights under this Agreement.




11.  Enforcement .
      The
      Executive agrees that the Corporation’s remedies at law for any breach or threat
      of breach by him of Sections 3, 4, 5 or 9 hereof will be inadequate, and that
      the Corporation shall be entitled to an injunction or injunctions to prevent
      breaches of Sections 3, 4, 5 or 9 hereof and to enforce specifically the terms
      and provisions thereof, in addition to any other remedy to which the Corporation
      may be entitled at law or equity. If the Corporation sues to enforce Sections
      3,
      4, 5 or 9 hereof and fails to prevail in such proceeding, the court shall award
      to the Executive his reasonable fees for his attorneys, the reasonable expenses
      of his witnesses, and any other reasonable expenses incurred in connection
      with
      the proceeding to the extent that the court determines that the Executive has
      prevailed in such proceeding.




12.  Arbitration .
      Any
      dispute or claim other than those referred to in Section 11, arising out of
      or
      relating to this Agreement or otherwise relating to the employment relationship
      between the Executive and the Corporation, shall be submitted to arbitration,
      in
      Fairfax County, Virginia, before a single arbitrator, in accordance with the
      rules of the American Arbitration Association as the exclusive remedy for such
      claim or dispute. The Executive and the Corporation agree that such arbitration
      will be confidential and no details, descriptions, settlements or other facts
      concerning such arbitration shall be disclosed or released to any third party
      without the specific written consent of the other party, unless required by
      law
      or court order or in connection with enforcement of any decision in such
      arbitration. Any damages awarded in such arbitration shall be limited to the
      contract measure of damages, and shall not include punitive damages. In any
      proceeding, whether commenced by the Executive or by the Corporation, the
      arbitrator shall award to the Executive his reasonable fees for his attorneys,
      the reasonable expenses of his witnesses, and any other reasonable expenses
      incurred in connection with the arbitration to the extent that the arbitrator
      determines that the Executive has prevailed in such proceeding.

13.  Full
      Settlement .
      The
      Corporation’s obligation to make any payments provided for in this Agreement and
      otherwise to perform its obligations hereunder shall not be affected by any
      set-off, counterclaim, recoupment, defense or other claim, right or action
      which
      the Corporation may have against the Executive or others. In no event shall
      the
      Executive be obligated to seek other employment or take other action by way
      of
      mitigation of the amounts payable to the Executive under any of the provisions
      of this Agreement, and such amounts shall not be reduced whether or not the
      Executive obtains other employment.




14.  Severability .
      Should
      any provision of this Agreement be determined to be unenforceable or prohibited
      by any applicable law, such provision shall be ineffective to the extent, and
      only to the extent, of such unenforceability or prohibition without invalidating
      the balance of such provision or any other provision of this Agreement, and
      any
      such unenforceability or prohibition in any jurisdiction shall not invalidate
      or
      render unenforceable such provision in any other jurisdiction.




15.  Counterparts .
      This
      Agreement may be executed in any number of counterparts, and each such
      counterpart shall be deemed to be an original instrument, but all such
      counterparts together shall constitute one and the same instrument.




16.  Assignment .
      The
      Executive’s rights and obligations under this Agreement shall not be assignable
      by the Executive. The Corporation's rights and obligations under this Agreement
      shall not be assignable by the Corporation except as incident to the transfer,
      by merger or otherwise, of all or substantially all of the business of the
      Corporation in a transaction in which the successor entity remains obligated
      under, or by operation of law or otherwise assumes, the Corporation’s
      obligations under this Agreement. In the event of any such assignment by the
      Corporation, all rights of the Corporation hereunder shall inure to the benefit
      of the assignee.




17.  Notices .
      Any
      notice required or permitted under this Agreement shall be deemed to have been
      effectively made or given if in writing and personally delivered or sent by
      registered or certified U.S. mail, UPS or recognized overnight courier, properly
      addressed in a sealed envelope, with delivery charges prepaid. Unless otherwise
      changed by notice, notice shall be properly addressed to the Executive if

18.  Compliance
      with Section 409A .
      Because
      the parties hereto intend that any payment under this Agreement shall be paid
      in
      compliance with Section 409A of the Code (“ Section
      409A ”)
      and
      all regulations, guidance and other interpretative authority thereunder, such
      that there will be no adverse tax consequences, interest or penalties as a
      result of such payments, the parties hereby agree to modify this Agreement
      with
      respect to the timing (but not the amount) of any payment to the extent
      necessary to comply with Section 409A and avoid application of any taxes,
      penalties or interest thereunder. Notwithstanding any provision of this
      Agreement to the contrary, if the Executive is a “specified employee” as defined
      in Section 409A, the Executive shall not be entitled to any payments upon Date
      of Termination until the earlier of (a) the date which is six (6) months after
      Date of Termination for any reason other than death, or (b) the date of the
      Executive’s death. Any amounts otherwise payable to the Executive following Date
      of Termination that are not so paid by reason of this Section 18 shall be paid
      as soon as practicable after the date that is six (6) months after Date of
      Termination (or, if earlier, the date of the Executive’s death). The provisions
      of this Section 18 shall only apply if, and to the extent, required to comply
      with Section 409A in a manner such that the Executive is not subject to
      additional taxes and/or penalties under Section 409A.





19.  Miscellaneous .
      Except
      for the separate agreement related to the award of restricted stock contemplated
      by Section 2(a), this Agreement constitutes the entire agreement, and terminates
      and supersedes all prior agreements, of the parties hereto relating to the
      subject matter hereof, and there are no written or oral terms or representations
      made by either party other than those contained herein, except that nothing
      contained in this Agreement shall invalidate or supersede the terms of any
      previously or subsequently granted stock options or other equity-based
      compensation arrangements (including without limitation the provisions thereof
      relating to post termination exercisability) to the extent that such stock
      options or arrangements provide more favorable terms to the Executive. The
      validity, interpretation, performance and enforcement of this Agreement shall
      be
      governed by the laws of the Commonwealth of Virginia, without giving effect
      to
      conflicts of laws principles. The headings contained herein are for reference
      purposes only and shall not in any way affect the meaning or interpretation
      of
      this Agreement.

      WITNESS WHEREOF, the parties hereto have executed this Amended and Restated
