    12. Further
      Assurances.
      The

      such other agreements, certificates, instruments and documents, as any Investor
      or the Transfer Agent or, in the case of the Holder or Successor, the Company,

      purposes of this Agreement and the consummation of the transactions contemplated
      hereby.

    

    13. No
      Strict Construction.

      Investors shall be entitled to seek temporary and permanent injunctive relief
      in
      any such case without the necessity of proving actual damages and without

      Company,
      Holder and Successor
      contained in this Agreement and this Section) as follows: (a) All Proceedings
      concerning the interpretations, enforcement and defense of the transactions

      hereunder or in connection herewith or with any transaction contemplated hereby
      or discussed herein, and hereby irrevocably waives, and agrees not to assert
      in
      any Proceeding, any claim that it is not personally subject to the jurisdiction
      of any such New York Court, or that such Proceeding has been commenced in an
      improper or inconvenient forum. (b) Each of the Company and the Holder hereby
      irrevocably waives personal service of process and consents to process being
      served in any such Proceeding by mailing a copy thereof via registered or
      certified mail or overnight delivery (with evidence of delivery) to such party
      at the address in effect for notices to it under this Agreement and agrees
      that
      such service shall constitute good and sufficient service of process and notice
      thereof. Nothing contained herein shall be deemed to limit in any way any right
      to serve process in any manner permitted by law. (c) Each of the Company and
      the

      of this Agreement, then the prevailing party in such Proceeding shall be
      reimbursed by the other party (and in the case of an Investor bringing such
      a
      Proceeding, the Company, Holder and Successor shall jointly and severally
      reimburse the Investor) for its reasonable attorneys’ fees and other costs and
      expenses incurred with the investigation, preparation and prosecution of such
      Proceeding.

      Funds (or portion thereof) delivered by the Investor(s) as directed by the
      Investor(s) without regard and irrespective of any other notices or
      instructions. If the Escrow Agent receives the notice contemplated under Section
      3.1(3) prior to a Termination Election (the “Disbursement
      Notice”),
      then
      the Escrow Agent shall disburse the Escrowed Funds in accordance with the funds
      flow memorandum attached hereto as Exhibit
      C.
      

    

    3.3 In
      accordance with Exhibit
      C,
      upon
      receipt of a Disbursement Notice, $4,250,000 of the Escrowed Funds are to be
      immediately transferred to the escrow account set forth in that certain Holdback
      Escrow Agreement, dated as of the date hereof, by and among the Company, the
      Escrow Agent and the Investors, in the form attached hereto as Exhibit
      D,
      to be
      held in escrow pursuant to the terms thereof.

    3.4 Should
      any controversy arise among the parties hereto with respect to this Agreement
      or
      with respect to the right to receive the Escrowed Funds, the Escrow Agent shall
      have the right to consult counsel and/or to institute an appropriate
      interpleader action to determine the rights of the parties. The Escrow Agent
      is
      also hereby authorized to institute an appropriate interpleader action upon
      receipt of a written letter of direction executed by Green and the Required
      Investors so directing the Escrow Agent. If the Escrow Agent is directed to
      institute an appropriate interpleader action, it shall institute such action
      not
      prior to thirty (30) days after receipt of such letter of direction and not
      later than sixty (60) days after such date. Any interpleader action instituted
      in accordance with this Section 3.4 shall be filed in any court of competent
      jurisdiction in Virginia, and the portion of the Escrowed Funds in dispute
      shall
      be deposited with the court and in such event the Escrow Agent shall be relieved
      of and discharged from any and all obligations and liabilities under and
      pursuant to this Agreement with respect to that portion of the Escrowed
      Funds.

    

    4.
       Exculpation
      and Indemnification of Escrow Agent

    

    4.1
       The
      Escrow Agent shall have no duties or responsibilities other than those expressly
      set forth herein. The Escrow Agent shall have no duty to enforce any obligation
      of any person to make any payment or delivery, or to direct or cause any payment
      or delivery to be made, or to enforce any obligation of any person to perform
      any other act. The Escrow Agent shall be under no liability to the other parties
      hereto or anyone else, by reason of any failure on the part of any other party
      hereto or any maker, guarantor, endorser or other signatory of a document or
      any
      other person, to perform such person’s obligations under any such document.
      Except for amendments to this Agreement referenced below, and except for written
      instructions given to the Escrow Agent by Green and the Required Investors
      (and
      if relevant the Placement Agent) relating to the Escrowed Funds, the Escrow
      Agent shall not be obligated to recognize any other agreement between or among
      the parties hereto relating to the subject matter hereof, notwithstanding that
      references hereto may be made herein and whether or not it has knowledge
      thereof. 

    

    4.2 Subject
      to its obligations upon receipt of a Termination Election, the Escrow Agent
      shall not be liable to Green, the Company or to anyone else for any action
      taken
      or omitted by it, or any action suffered by it to be taken or omitted, in good
      faith and acting upon any order, notice, demand, certificate, opinion or advice
      of counsel (including counsel chosen by the Escrow Agent), statement,
      instrument, report, or other paper or document (not only as to its due execution
      and the validity and effectiveness of its provisions, but also as to the truth
      and acceptability of any information therein contained), which is believed
      by
      the Escrow Agent to be genuine and to be signed or presented by the proper
      person or persons. The Escrow Agent shall not be bound by any of the terms
      thereof, unless evidenced by written notice delivered to the Escrow Agent signed
      by the proper party or parties and, if the duties or rights of the Escrow Agent
      are affected, unless it shall give its prior written consent
      thereto.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    4.3 The
      Escrow Agent shall not be responsible for the sufficiency or accuracy of the
      form, or of the execution, validity, value or genuineness of, any document
      or
      property received, held or delivered to it hereunder, or of any signature or
      endorsement thereon, or for any lack of endorsement thereon, or for any
      description therein; nor shall the Escrow Agent be responsible or liable to
      Green or to anyone else in any respect on account of the identity, authority
      or
      rights, of the person executing or delivering or purporting to execute or
      deliver any document or property or this Agreement. The Escrow Agent shall
      have
      no responsibility with respect to the use or application of the Escrowed Funds
      pursuant to the provisions hereof.

    

    4.4 The
      Escrow Agent shall have the right to assume, in the absence of written notice
      to
      the contrary from the proper person or persons, that a fact or an event, by
      reason of which an action would or might be taken by the Escrow Agent, does
      not
      exist or has not occurred, without incurring liability to Green or to anyone
      else for any action taken or omitted to be taken or omitted, in good faith
      and
      in the exercise of its own best judgment, in reliance upon such
      assumption.

    

    4.5 To
      the
      extent that the Escrow Agent becomes liable for the payment of taxes, including
      withholding taxes, in respect of income derived from the investment of the
      Escrowed Funds, or any payment made hereunder, the Escrow Agent may pay such
      taxes; and the Escrow Agent may withhold from any payment of the Escrowed Funds
      to the Company (but not any payments to the Investors or pursuant to Section
      3.3) such amount as the Escrow Agent estimates to be sufficient to provide
      for
      the payment of such taxes not yet paid, and may use the sum withheld for that
      purpose. The Escrow Agent shall be indemnified and held harmless by Green
      against any liability for taxes and for any penalties in respect of taxes,
      on
      such investment income or payments in the manner provided in Section
      4.6.

    

    4.6 The
      Escrow Agent will be indemnified and held harmless by the Company from and
      against all expenses, including all counsel fees and disbursements, or loss
      suffered by the Escrow Agent in connection with any action, suit or proceedings
      involving any claim, or in connection with any claim or demand, which in any
      way, directly or indirectly, arises out of or relates to this Agreement, the
      services of the Escrow Agent hereunder, except for claims relating to gross
      negligence by Escrow Agent or breach of this Agreement by the Escrow Agent,
      or
      the monies or other property held by it hereunder. Promptly after the receipt
      of
      the Escrow Agent of notice of any demand or claim or the commencement of any
      action, suit or proceeding, the Escrow Agent shall, if a claim in respect
      thereof is to be made against Green, notify it thereof in writing, but the
      failure by the Escrow Agent to give such notice shall not relieve any such
      party
      from any liability which Green may have to the Escrow Agent hereunder.
      Notwithstanding any obligation to make payments and deliveries hereunder, the
      Escrow Agent may retain and hold for such time as it deems necessary such amount
      of monies or property as it shall, from time to time, in its sole discretion,
      seem sufficient to indemnify itself for any such loss or expense and for any
      amounts due it under Section 7. 

    

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

       

    

    4.7 For
      purposes hereof, the term “expense or loss” shall include all amounts paid or
      payable to satisfy any claim, demand or liability, or in settlement of any
      claim, demand, action, suit or proceeding settled with the express written
      consent of the Escrow Agent, and all costs and expenses, including, but not
      limited to, counsel fees and disbursements, paid or incurred in investigating
      or
      defending against any such claim, demand, action, suit or proceeding.

    

    5.
       Termination
      of Agreement and Resignation of Escrow Agent 

    

    5.1 This
      Agreement shall terminate and be of no further force or effect on the earlier
      of
      (i) disbursement of all Escrowed Funds and (ii) the one year anniversary of
      the
      Closing Date; provided that the rights of the Escrow Agent and the Investors
      and
      the obligations of Green under Section 4 shall survive the termination
      hereof.

    

    5.2 The
      Escrow Agent may resign at any time and be discharged from its duties as Escrow
      Agent hereunder by giving Green at least five (5) business days written notice
      thereof (the “Notice Period”). As soon as practicable after its resignation, the
      Escrow Agent shall, if it receives notice from Green within the Notice Period,
      turn over to a successor escrow agent appointed by Green all Escrowed Funds
      (less such amount as the Escrow Agent is entitled to retain pursuant to Section
      7) upon presentation of the document appointing the new escrow agent and its
      acceptance thereof. If no new agent is so appointed within the Notice Period,
      the Escrow Agent shall return the Escrowed Funds to the parties from which
      they
      were received without interest or deduction. 

    

    6.
       Form
      of Payments by Escrow Agent.

      Fee:
      Green
      shall pay a fee of $500.00 to the Escrow Agent upon its receipt of a
      Disbursement Notice. 

    

    7.3 Interest :
      The
      Escrowed Funds shall accrue interest (the “Accrued
      Interest”)
      at the
      available rate obtained by the Escrow Agent with respect to the period during
      which such funds are held in the Escrow Account. Each
      time
      Escrowed Funds are disbursed to the Company in accordance with this Agreement,
      Green shall be paid Accrued Interest of 2.0% per annum on the aggregate amount
      of Escrowed Funds disbursed to the Company at such time and the balance of
      Accrued Interest, if any, shall be retained by the Escrow Agent.

     

    
      
        
        

      

      
        5

      to time on and after the date hereof, Green shall deliver or cause to be
      delivered to the Escrow Agent such further documents and instruments and shall
      do and cause to be done such further acts as the Escrow Agent shall reasonably
      request (it being understood that the Escrow Agent shall have no obligation
      to
      make any such request) to carry out more effectively the provisions and purposes
      of this Agreement, to evidence compliance herewith or to assure itself that
      it
      is protected in acting hereunder.

      requiring construction against the party causing such instrument to be drafted.
      The terms “hereby,” “hereof,” “hereunder,” and any similar terms, as used in

      deemed to include any other number and any other gender as the context may
      require. This Agreement shall not be admissible in evidence to construe the
      provisions of any prior agreement. 

    

    11.2 This
      Agreement and the rights and obligations hereunder of Green may not be assigned.
      This Agreement and the rights and obligations hereunder of the Escrow Agent
      may
      be assigned by the Escrow Agent, with the prior consent of Green and the

      benefit of each party’s respective successors, heirs and permitted assigns. No

      supplemented without an express written agreement executed by the Escrow Agent,
      Green and the Investors. This Agreement is intended to be for the sole benefit
      of the parties hereto and their respective successors, heirs and permitted
      assigns, and none of the provisions of this Agreement are intended to be, nor
      shall they be construed to be, for the benefit of any third person, other than
      the Placement Agent.

      Agreement shall be governed by, and construed in accordance with, the internal
      laws of the State of Virginia. The representations and warranties contained
      in
      this Agreement shall survive the execution and delivery hereof and any
      investigations made by any party. The headings in this Agreement are for
