**7.**  **NON-COMPETITION** **AND NON-SOLICITATION.**




(a)  For
      as
      long as Executive shall remain employed by Employer and for (i) one year if
      terminated by Employer for Cause or by Employee for any reason and (ii) the
      applicable following period if terminated by Employer without Cause pursuant
      to
      Section 11(f): (x) one year if terminated during the Initial Term; or (y) nine
      months if terminated after the Initial Term (the “ Non-Competition
      Period ”),
      Executive shall not, directly or indirectly, as principal, agent, Executive,
      employer, consultant, independent contractor, stockholder, partner or in any
      other individual capacity whatsoever (except as permitted herein), engage in
      any
      Competitive Business Activities without the written consent of Employer which
      shall not unreasonably be withheld. For purposes of this Agreement,
“ Competitive
      Business Activity ”
means
      any business activities that are competitive with the activities of Employer
      as
      of the Effective Date. The foregoing shall not prevent Executive from owning
      for
      investment purposes up to 5% of the outstanding securities of a publicly traded
      company engaged in a Competitive Business Activity (provided that, in
      no event shall Executive own more than 5% of the outstanding securities of
      a
      publicly traded company engaged in a Competitive Business Activity).




(b)  For
      a
      period equal to the longer of (i) five (5) years after the Effective Date and
      (ii) two (2) years after Executive ceases, for any reason, to be employed by
      Employer or its affiliates, Executive shall not (for his own benefit or for
      the
      benefit of any person other than Employer and its affiliates), for the
      Non-Competition Period, solicit, or assist any person other than Employer to
      solicit, any officer, director, executive or Executive of Employer or any of
      their respective affiliates to leave his or her employment.




(c)  During
      the Non-Competition Period, Executive shall not, either himself, or for the
      benefit of any other person, either as Executive, consultant, investor or in
      any
      other capacity whatsoever, contact any Customer or Prospective Customer for
      the
      purpose of selling any products or services that constitute a Competitive
      Business Activity. For purposes of this Agreement, “ Customer ”
means
      any Person who has purchased products or services from Employer and its
      affiliates at any time within two (2) years prior to the Effective Date, and
      “ Prospective
      Customer ”
means
      any Person who Employer and its affiliates will actively solicit (or had
      targeted for solicitation) as of the Effective Date.




(d)  Executive
      has carefully read and considered the provisions of this Section 7, and,
      having done so, agrees that (i) the restrictions set forth herein are
      reasonable, in terms of scope, duration, geographic scope and otherwise, (ii)
      Employer is in the process of expanding its operations and Executive will have
      access to critical information regarding its operations and therefore the broad
      scope of the restrictions relating to Employer’s business are necessary, (iii)
      the protection afforded to Employer hereunder is necessary to protect its
      legitimate business interests and is no greater than necessary to protect
      Employer’s legitimate business interests, (iv) the agreement to observe such
      restrictions forms a material part of the consideration for this Agreement
      and
      Executive’s employment by Employer and (v) upon the termination of Executive’s
      employment with Employer for any reason, she will be able to earn a livelihood
      without violating the foregoing restrictions. In the event that, notwithstanding
      the foregoing, any of the provisions of this Section 7 shall be held to be
      invalid or unenforceable, the remaining provisions thereof shall nevertheless
      continue to be valid and enforceable as though the invalid or unenforceable
      parts had not been included therein. In the event that any provision of this
      Section 7 relating to the time period and/or the areas of restriction and/or
      related aspects shall be declared by a court of competent jurisdiction to exceed
      the maximum restrictiveness such court deems reasonable and enforceable, the
      time period and/or areas of restriction and/or related aspects deemed reasonable
      and enforceable by the court shall become and thereafter be the maximum
      restriction in such regard, and the restriction shall remain enforceable to
      the
      fullest extent deemed reasonable by such court.

(e)  Executive
      agrees that Employer’s remedies at law for any breach or threat of breach by his
      of any of the provisions of this Section 7 will be inadequate and that Employer
      shall be entitled to seek an injunction or injunctions to prevent breaches
      of
      the provisions of this Section 7 and to enforce specifically the terms and
      provisions thereof, in addition to any other remedy to which Employer may be
      entitled at law or equity. Employer agrees that the Employee’s obligations under
      this Section 7 are contingent upon the Employer fulfilling its obligations
      to
      make the payments required by Section 11, Section 12, and Section 13.




**8.**  **TRADE
      SECRETS** .
      Executive shall not use or disclose any of Employer’s trade secrets or other

      scientific, trade and engineering secrets, “know-how,” formulae, secret
      processes or machines, inventions, computer programs (including documentation

      proprietary information about costs, profits, markets, sales, lists of
      customers, plans for future development, and other information of a similar
      nature that is designated as confidential or generally maintained as
      confidential or proprietary by Employer. After termination of Executive’s
      employment, Executive shall not use or disclose trade secrets or other
      confidential information unless such information becomes a part of the public
      domain other than through a breach of Employer’s policies or is disclosed to
      Executive by a third party who is entitled to receive and disclose such
      information.




**9.**  **RETURN
      OF DOCUMENTS AND PROPERTY.** **** Upon
      the
      effective date of notice of Executive’s or Employer’s election to terminate

      information relating to Employer’s business and affairs, and (b) all documents,

      discoveries and works, and (c) promptly execute, whether during his employment
      by Employer or thereafter, all applications or other endorsements necessary
      or

      termination of Executive’s employment by Employer, are made, disclosed, reduced
      to a tangible or written form or description, or are reduced to practice by
      Employer and which pertain to the business carried on or products or services
      being sold or developed by Employer at the time of such termination shall,
      as
      between Executive and Employer, be presumed to have been made during Executive’s
      employment by Employer. Set forth on Schedule

                and




(iii)
            provide

                expressly provided under this Section 11, Section 12 or Section 13,
                as
                applicable.




Any
      payments under this Section 11, Section 12 or Section 13 that are to be made
      in
      connection with the termination of Executive’s employment are subject to the

      ten (10) business days of Executive’s termination of employment; provided , however ,
      that in
      the event Executive’s employment is terminated pursuant to Section 11(b) below,

      other compensation and employment benefit arrangements provided for in this
      Agreement shall cease upon such termination of employment except to the extent
      required by law or otherwise expressly provided by such arrangements.




(b)  In
      the
      event Employer terminates Executive’s employment without Cause or Executive

      equal to Executive’s then applicable Base Compensation for a period of twelve
      (12) months following the termination of employment if the termination takes
      place during the Initial Term, or a severance benefit equal to Executive’s then
      applicable Base Compensation for a period of nine (9) months following the
      termination of employment if the termination takes place after the Initial
      Term
      (such twelve- or nine-month period, as the case may be, the “ Applicable
      Severance Period ”),
      and
      (ii) an amount equal to fifty percent (50%) of the Incentive Compensation
      Target(s), if any, applicable for the calendar year ending during the Applicable

      employment with Employer is terminated, Employer shall calculate the amount
      of
      Incentive Compensation Executive would have received had Executive remained
      employed by Employer for the entire applicable calendar year. To the extent
      that
      the amount of the Incentive Compensation Executive would have received had
      Executive remained employed by Employer for the entire applicable calendar
      year
      is in excess of 50% of the Incentive Compensation Target for that year (the
      “ Overage
      Amount ”),
      Employer shall then promptly pay to Executive the Overage Amount. No Overage
      Amount shall be payable in respect of years following the year in which

      assertion of Good Reason shall be null and void.




(f)  For
      purposes of this Agreement, Employer shall have “ Cause ”

      terminate Executive’s employment hereunder upon (i) the continued, willful and
      deliberate failure of Executive to perform his duties in a manner substantially

      than
      any such failure resulting from his incapacity due to physical or mental
      illness), (ii) the engaging by Executive in misconduct materially and

      and
      obligations of the parties; provided,

                other than an employee benefit plan of Employer, immediately after
                which
                such person or group has “Beneficial Ownership” (within the meaning of
                Rule 13d-3 under the Exchange Act) of more than fifty percent (50%)

                consummation of (A) a merger, consolidation or reorganization involving
                Employer, unless the company resulting from such merger, consolidation

                reorganization (the “Surviving

(d)  In
      the
      event that, as a result of payments to or for the benefit of Executive under
      this Agreement or otherwise in connection with a Change in Control, any state,
      local or federal taxing authority imposes any taxes on Executive that would
      not
      be imposed but for the occurrence of a Change in Control, including any excise
      tax under Section 4999 of the Internal Revenue Code and any successor or
      comparable provision, then, in addition to the benefits provided for under
      Sections 11(a)(i) and 11(a)(ii) and under Sections 12(a) and 12(b), Employer
      (including any successor to Employer) shall pay to Executive at the time any
      such tax becomes payable an amount equal to the amount of any such tax imposed

**13.**  **DISABILITY;
      DEATH** **.**




(a)  If,
      prior
      to the expiration or termination of the Employment Term, Executive shall be
      unable to perform his duties by reason of disability or impairment of health
      for
      at least six consecutive calendar months, Employer shall have the right to
      terminate Executive’s employment on account of disability by giving written
      notice to 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 Executive is disabled within the meaning of this Section 13(a),
      either party may from time to time request a medical examination of Executive
      by
      a doctor selected by Employer, and the written medical opinion of such doctor
      shall be conclusive and binding upon the parties as to whether Executive has
      become disabled and the date when such disability arose. The cost of any such
      medical examination shall be borne by Employer. If Employer terminates
      Executive’s employment on account of disability, then, in addition to the
      benefits provided for under Sections 11(a)(i) and 11(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.




(b)  If,
      prior
      to the expiration or termination of the Employment Term, Executive shall die,
      then, in addition to the benefits provided for under Sections 11(a)(i) and
      11(a)(ii), the Employment Term 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 13 shall impair or otherwise affect any rights and
      interests of Executive under any insurance arrangements, death benefit plan
      or
      other compensation plan or arrangement of Employer which may be adopted by
      the
      Board.




**14.**  **LAW
      APPLICABLE** .
      This
      Agreement shall be governed by and construed pursuant to the laws of the
      Commonwealth of Virginia, without giving effect to conflicts of laws
      principles.

**16.**  **ASSIGNMENT,
      ETC** .
      This
      Agreement shall inure to the benefit of and be binding upon the parties hereto
      and their respective legal representatives, heirs, assignees and/or successors
      in interest of any kind whatsoever; provided , however ,
      that
      Executive acknowledges and agrees that he cannot assign or delegate any of
      his
      rights, duties, responsibilities or obligations hereunder to any other person
      or
      entity. Employer may assign its rights under this Agreement to any affiliate
      of
      Employer or to any entity upon any sale of all or substantially all of the
      assets of Employer, or upon any merger or consolidation of Employer with or
      into
      any other entity, provided that
      such assignment shall not relieve Employer of its obligations hereunder without
      the written consent of Executive.




**17.**  **ENTIRE
      AGREEMENT; MODIFICATIONS** .
      This
      Agreement constitutes the entire final agreement between the parties with
      respect to, and supersedes any and all prior agreements between the parties
      hereto both oral and written concerning, the subject matter hereof and may
      not
      be amended, modified or terminated except by a writing duly signed by the
      parties hereto.




**18.**  **SEVERABILITY** .
      If any
      provision of this Agreement shall be held to be invalid or unenforceable, and
      is
      not reformed by a court of competent jurisdiction, such invalidity or
      unenforceability shall attach only to such provision and shall not in any way
      affect or render invalid or unenforceable any other provision of this Agreement,
      and this Agreement shall be carried out as if such invalid or unenforceable
      provision were not contained herein.




**19.**  **NO
      WAIVER** .
      A
      waiver of any breach or violation of any term, provision or covenant contained
      herein shall not be deemed a continuing waiver or a waiver of any future or
      past
      breach or violation. No oral waiver shall be binding. The failure of a party
      to
      insist upon strict adherence to any term of this Agreement on one or more
      occasions shall not be considered a waiver or deprive that party of the right
      thereafter to insist upon strict adherence to that term or any other term of
      this Agreement.




**20.**  **ARBITRATION** .




(a)  Agreement
      to Arbitrate .
      In the
      event of differences between Employer and Executive arising out of or relating
      to his employment with Employer or the termination of that employment, Executive
      and Employer mutually agree to arbitration. Executive understands that his
      assent to mandatory arbitration is a condition of employment and continued
      employment. Any claim or controversy that arises out of or relates to this
      Agreement or the breach of it, as well as all other claims made arbitrable
      by
      this Agreement, will be settled by arbitration in the Commonwealth of Virginia
      in accordance with the rules of the American Arbitration Association. Judgment
      upon the award rendered may be entered in any court possessing jurisdiction
      of
      arbitration awards. A request by a party to a court for interim measures or
      specific performance necessary to preserve a party’s rights and remedies for
      resolution pursuant to this Section 20 shall not be deemed a waiver of the
      agreement to arbitrate. The parties, their representatives, other participants
      and arbitrator shall hold the existence, content and result of the arbitration
      in confidence.




(b)  Covered
      Claims .
      Except
      as otherwise provided in this Agreement, Executive and Employer hereby consent
      to the resolution by arbitration of all claims or controversies for which a
      court otherwise would be authorized by law to grant relief, in any way arising
      out of, relating to, or associated with Executive’s employment with Employer or
      its termination (“ Claims ”)
      that
      Employer may have against Executive or that Executive may have against Employer
      or against its officers, directors, employees, or agents, in their capacity
      as
      such or otherwise. The Claims covered by this Agreement include, but are not
      limited to: claims for discrimination based on race, sex, religion, national
      origin, age, marital status, handicap, disability, or medical condition; claims
      for benefits, except as excluded in the following paragraph, and claims for
      violation of any federal, state, or other governmental constitution, statute,
      ordinance, or regulation (including but not limited to claims arising under
      Title VII of the Civil Rights Act, the Americans with Disabilities Act, the
      Age
      Discrimination in Employment Act, the Family Medical Leave Act, the Fair Labor
      Standards Act, and Employee Retirement Income Security Act). Additionally,
      any
      and all issues of arbitrability (whether a claim is covered by this Agreement)
      will be decided by the arbitrator(s) and not a court.

(c)  Claims
      Not Covered .
      This
      agreement to arbitrate does not apply to or cover claims for workers’
compensation benefits; claims for unemployment compensation benefits; claims
      by
      Employer for injunctive and/or other equitable relief for breach of
      Section 7 or for unfair competition and/or the use and/or unauthorized
      disclosure of trade secrets or confidential information; and claims based upon
      an employee pension or benefit plan, the terms of which contain an arbitration
      or other non-judicial dispute resolution procedure, in which case the provisions
      of such plan shall apply.




**21.**  **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 the timing (but
      not
      the amount) of any payment hereunder to the extent necessary to comply with
      Section 409A and avoid application of any taxes, penalties or interest
      thereunder. Consequently, notwithstanding any provision of this Agreement to
      the
      contrary, if Executive is a “specified employee” as defined in Section 409A,
      Executive shall not be entitled to any payments upon Date of Termination until
      the earlier of (i) the date which is six (6) months after Date of Termination
      for any reason other than death, or (ii) the date of Executive’s death. Any
      amounts otherwise payable to Executive following Date of Termination that are
      not so paid by reason of this Section 21 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 Executive’s death). The provisions of this Section 21 shall only
      apply if, and to the extent, required to comply with Section 409A in a manner
      such that Executive is not subject to additional taxes and/or penalties under
      Section 409A.




**22.**  **COUNTERPARTS** .
      This
      Agreement may be executed in counterparts, each of which shall be an original,
      but all of which together shall constitute one and the same instrument, and
      it
      shall not be necessary in making proof of this agreement to account for all
      such
      counterparts.
