    1. DURATION
      AND EXERCISE OF WARRANTS

    

    (a)   Exercise
      Period.
      The
      Holder may exercise this Warrant in whole or in part on any Business Day on
      or
      before 5:00 P.M., Eastern Time, on the Expiration Date, at which time this
      Warrant shall become void and of no value.

     

    (b)    Exercise
      Procedures.

    

    (i)   
       While
      this Warrant remains outstanding and exercisable in accordance with Section
      1(a),
      in
      addition to the manner set forth in Section 1(b)(ii) below, the Holder may
      exercise this Warrant in whole or in part
      at any
      time and from time to time
      by:

    

      
      (A)     delivery
      to the Company of a duly executed copy of the Notice of Exercise attached as
      Exhibit
      A;

    

     
      (B)     surrender
      of this Warrant to the Secretary of the Company at its principal offices or
      at
      such other office or agency as the Company may specify in writing to the Holder;
      and

    

     
      (C)     payment
      of the then-applicable
      Exercise
      Price per share multiplied by the number of Warrant Shares being purchased
      upon
      exercise of the Warrant (such amount, the “Aggregate
      Exercise Price”)
      made
      in
      the form of cash, or by certified check, bank draft or money order payable
      in
      lawful money of the United States of America
      or in
      the form of a Cashless Exercise
      to the
      extent permitted in Section 1(b)(ii)
      below.

    

     
      (ii)     While
      this Warrant remains outstanding and exercisable in accordance with Section
      1(a), the Holder may, in its sole discretion, exercise all or any part of the
      Warrant in a “cashless” or “net-issue” exercise (a “Cashless
      Exercise”)
      by
      delivering to the Company (1) the Notice of Exercise and (2) the original
      Warrant,
      pursuant to which the Holder shall surrender the right to receive upon exercise
      of this Warrant, a number of Warrant Shares having a value (as determined below)
      equal to the Aggregate Exercise Price, in which case, the number of Warrant
      Shares to be issued to the Holder upon such exercise shall be calculated using
      the following formula:

     

    
 

    
      	 	
              X

            	
              =

            	
              Y
                * (A - B)

            	 
	 	
            	 	
              A

            	 

    

      

    
      	
            	with:	
              X
                =      the
                number of Warrant Shares to be issued to the
                Holder

            

    

    

    Y
      =     the
      number of Warrant Shares with respect to which the Warrant is being
      exercised

    

    A
      =     the
      fair
      value per share of Common
      Stock on
      the
      date of exercise of this Warrant

    

    B
      =     the
      then-current Exercise Price of
      the
      Warrant

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

       

    

    Solely
      for the purposes of this paragraph, “fair value” per share of Common Stock shall
      mean (A) the average of the closing sales prices, as quoted on the primary
      national or regional stock exchange on which the Common Stock is listed,
or,
      if not
      listed,
      the OTC
      Bulletin Board if quoted thereon, on the twenty
      (20)
      trading
      days immediately preceding the date on which the Notice of Exercise is deemed
      to
      have been sent to the Company, or (B) if the Common Stock is not publicly traded
      as set forth above, as reasonably and in good faith determined by the Board
      of
      Directors of the Company as of the date which the Notice of Exercise is deemed
      to have been sent to the Company.

    

    Notwithstanding
      the foregoing provisions of this Section 1(b)(ii), the Holder may not make
      a
      Cashless Exercise if and to the extent that such exercise would require the
      Company to issue a number of shares of Common Stock in excess of its authorized
      but unissued shares of Common Stock, less all amounts of Common Stock that
      have
      been reserved for issue upon the conversion of all outstanding securities
      convertible into shares of Common Stock and the exercise of all outstanding
      options, warrants and other rights exercisable for shares of Common Stock.
      If
      the Company does not have the requisite number of authorized but unissued shares
      of Common Stock to permit the Holder to make a Cashless Exercise, the Company
      shall use commercially reasonable efforts to obtain the necessary stockholder
      consent to increase the authorized number of shares of Common Stock to permit
      such Holder to make a Cashless Exercise pursuant to this Section
      1(b)(ii).

    

    (iii)  
       Upon
      the exercise
      of this
      Warrant in compliance with the provisions of this Section 1(b), and except
      as
      limited pursuant to the last paragraph of Section 1(b)(ii), the Company shall
      promptly issue and cause to be delivered to the Holder a certificate for the
      Warrant Shares purchased by the Holder. Each
      exercise of this Warrant shall be effective immediately prior to the close
      of
      business on the date (the “Date
      of Exercise”)
      that
      the
      conditions set forth in Section 1(b) have been satisfied, as the case may
      be.
      On
      the
      first Business Day following the date on which the Company has received each
      of
      the Notice of Exercise and the Aggregate Exercise Price (or notice of a Cashless
      Exercise in accordance with Section 1(b)(ii)) (the “Exercise
      Delivery Documents”),
      the
      Company shall transmit an acknowledgment of receipt of the Exercise Delivery
      Documents to the Company’s transfer agent (the “Transfer
      Agent”).
      On or
      before the third Business Day following the date on which the Company has
      received all of the Exercise Delivery Documents (the “Share
      Delivery Date”),
      the
      Company shall (X) provided that the Transfer Agent is participating in The
      Depository Trust Company (“DTC”)
      Fast
      Automated Securities Transfer Program, upon the request of the Holder, credit
      such aggregate number of shares of Common Stock to which the Holder is entitled
      pursuant to such exercise to the Holder’s or its designee’s balance account with
      DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the
      Transfer Agent is not participating in the DTC Fast Automated Securities
      Transfer Program, issue and dispatch by overnight courier to the address as
      specified in the Notice of Exercise, a certificate, registered in the Company’s
      share register in the name of the Holder or its designee, for the number of
      shares of Common Stock to which the Holder is entitled pursuant to such
      exercise. Upon delivery of the Exercise Delivery Documents, the Holder shall
      be
      deemed for all corporate purposes to have become the holder of record of the
      Warrant Shares with respect to which this Warrant has been exercised,
      irrespective of the date of delivery of the certificates evidencing such Warrant
      Shares. If this Warrant is submitted in connection with any exercise pursuant
      to
      Section 1(a) and the number of Warrant Shares represented by this Warrant
      submitted for exercise is greater than the actual
      number
      of
      Warrant Shares being acquired upon such an
      exercise, then the Company shall as soon as practicable and in no event later
      than three (3) Business Days after any exercise and at its own expense, issue
      a
      new Warrant of
      like
      tenor
      representing the right to purchase the number of Warrant Shares purchasable
      immediately prior to such exercise under this Warrant, less the number of
      Warrant Shares with respect to which this Warrant is exercised.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    (iv)  
       If
      the
      Company shall fail for any reason or for no reason to issue to the Holder,
      within three (3) Business Days of receipt of the Exercise Delivery Documents,
      a
      certificate for the number of shares of Common Stock to which the Holder is
      entitled and register such shares of Common Stock on the Company’s share
      register or to credit the Holder’s balance account with DTC for such number of
      shares of Common Stock to which the Holder is entitled upon the Holder’s
      exercise of this Warrant, and if on or after such Business Day the Holder
      purchases (in an open market transaction or otherwise) shares of Common Stock
      to
      deliver in satisfaction of a sale by the Holder of shares of Common Stock
      issuable upon such exercise that the Holder anticipated receiving from the
      Company (a “Buy-In”),
      then
      the Company shall, within three (3) Business Days after the Holder’s request and
      in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal
      to the Holder’s total purchase price (including brokerage commissions, if any)
      for the shares of Common Stock so purchased (the “Buy-In
      Price”),
      at
      which point the Company’s obligation to deliver such certificate (and to issue
      such shares of Common Stock) shall terminate, or (ii) promptly honor its
      obligation to deliver to the Holder a certificate or certificates representing
      such shares of Common Stock and pay cash to the Holder in an amount equal to
      the
      excess (if any) of the Buy-In Price over the product of (A) such number of
      shares of Common Stock, times (B) the closing bid price on
      the
      date of exercise. 

    

    (c)  
       Partial
      Exercise.
      This
      Warrant shall be exercisable, either in its entirety or, from time to time,
      for
      part only of the number of Warrant Shares referenced by this Warrant. If this
      Warrant is exercised in part, the Company shall issue, at its expense, a new
      Warrant, in substantially the form of this Warrant, referencing such reduced
      number of Warrant Shares that remain subject to this Warrant.

    

    (d)   
       Disputes.
      In the
      case of a dispute as to the determination of the Exercise Price or the
      arithmetic calculation of the Warrant Shares, the Company shall promptly issue
      to the Holder the number of Warrant Shares that are not disputed and resolve
      such dispute in accordance with Section 15.

    

    2.     ISSUANCE
      OF WARRANT SHARES

    

    (a)  
       The
      Company covenants that all Warrant Shares will, upon issuance in accordance
      with
      the terms of this Warrant, be (i) duly authorized, fully paid and
      non-assessable, and (ii) free from all liens, charges and security interests,
      with the exception of claims arising through the acts or omissions of any Holder
      and except as arising from applicable Federal and state securities
      laws.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    (b)   
       The
      Company shall register this Warrant upon records to be maintained by the Company
      for that purpose in the name of the record holder of such Warrant from time
      to
      time. The Company may deem and treat the registered Holder of this Warrant
      as
      the absolute owner thereof for the purpose of any exercise thereof, any
      distribution to the Holder thereof and for all other purposes.

    

    (c)   
       The
      Company will not, by amendment of its articles of incorporation, by-laws or
      through any reorganization, transfer of assets, consolidation, merger,
      dissolution, issue or sale of securities or any other voluntary action, avoid
      or
      seek to avoid the observance or performance of any of the terms to be observed
      or performed hereunder by the Company, but will at all times in good faith
      assist in the carrying out of all the provisions of this Warrant and in the
      taking of all action necessary or appropriate in order to protect the rights
      of
      the Holder to exercise this Warrant,
      or
      against impairment of such rights.

    

    3.     ADJUSTMENTS
      OF EXERCISE PRICE, NUMBER AND TYPE OF WARRANT SHARES

    

    (a)   
       The
      Exercise Price and the number of shares purchasable upon the exercise of this
      Warrant shall be subject to adjustment from time to time upon the occurrence
      of
      certain events described in this Section 3(a); provided,
      that
      notwithstanding the provisions of this Section 3, the Company shall not be
      required to make any adjustment if and to the extent that such adjustment would
      require the Company to issue a number of shares of Common Stock in excess of
      its
      authorized but unissued shares of Common Stock, less all amounts of Common
      Stock
      that have been reserved for issue upon the conversion of all outstanding
      securities convertible into shares of Common Stock and the exercise of all
      outstanding options, warrants and other rights exercisable for shares of Common
      Stock. If the Company does not have the requisite number of authorized but
      unissued shares of Common Stock to make any adjustment, the Company shall use
      its commercially best efforts to obtain the necessary stockholder consent to
      increase the authorized number of shares of Common Stock to make such an
      adjustment pursuant to this Section 3(a).

    

    (i)   
       Subdivision
      or Combination of Stock.
      In case
      the Company shall at any time subdivide (whether
      by way of stock dividend, stock split or otherwise) its
      outstanding shares of Common Stock into a greater number of shares, the Exercise
      Price in effect immediately prior to such subdivision shall be proportionately
      reduced and
      the
      number of Warrant Shares shall be proportionately increased,
      and
      conversely, in case the outstanding shares of Common Stock of the Company shall
      be combined (whether
      by way of stock combination, reverse stock split or otherwise) into
      a
      smaller number of shares, the Exercise Price in effect immediately prior to
      such
      combination shall be proportionately increased
      and the
      number of Warrant Shares shall be proportionately decreased. The Exercise Price
      and the Warrant Shares, as so adjusted, shall be readjusted in the same manner
      upon the happening of any successive event or events described in this Section
      3(a)(i).

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    (ii)   
       Dividends
      in Stock, Property, Reclassification.
      If at
      any time, or from time to time, the holders of Common Stock (or any shares
      of
      stock or other securities at the time receivable upon the exercise of this
      Warrant) shall have received or become entitled to receive, without payment
      therefore:

    

    (A)   
       any
      shares of stock or other securities that are at any time directly or indirectly
      convertible into or exchangeable for Common Stock, or any rights or options
      to
      subscribe for, purchase or otherwise acquire any of the foregoing by way of
      dividend or other distribution, or

    

    (B)   
       additional
      stock or other securities or property (including cash) by way of spin-off,
      split-up, reclassification, combination of shares or similar corporate
      rearrangement (other than shares of Common Stock issued as a stock split or
      adjustments in respect of which shall be covered by the terms of Section 3(a)(i)
      above),

    

    then
      and
      in each such case, the Exercise
      Price and the number of Warrant Shares to be obtained upon exercise of this
      Warrant shall be adjusted proportionately, and the Holder
      hereof shall, upon the exercise of this Warrant, be entitled to receive, in
      addition to the number of shares of Common Stock receivable thereupon, and
      without payment of any additional consideration therefor, the amount of stock
      and other securities and property (including cash in the cases referred to
      above) that such Holder would hold on the date of such exercise had such Holder
      been the holder of record of such Common Stock as of the date on which holders
      of Common Stock received or became entitled to receive such shares or all other
      additional stock and other securities and property.
      The
      Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted
      in
      the same manner upon the happening of any successive event or events described
      in this Section 3(a)(ii).

    

    (iii)   
       Reorganization,
      Reclassification, Consolidation, Merger or Sale.
      If any
      recapitalization, reclassification or reorganization of the capital stock of
      the
      Company, or any consolidation or merger of the Company with another corporation,
      or the sale of all or substantially all of its assets or other
      transaction shall be effected in such a way that holders of Common Stock shall
      be entitled to receive stock, securities, or other assets or property (an
“Organic
      Change”),
      then,
      as a condition of such Organic Change, lawful and adequate provisions shall
      be
      made by the Company whereby the Holder hereof shall thereafter have the right
      to
      purchase and receive (in lieu of the shares of the Common Stock of the Company
      immediately theretofore purchasable and receivable upon the exercise of the
      rights represented by this Warrant) such shares of stock, securities or other
      assets or property as may be issued or payable with respect to or in exchange
      for a number of outstanding shares of such Common Stock equal to the number of
      shares of such stock immediately theretofore purchasable and receivable assuming
      the full exercise of the rights represented by this Warrant. In the event of
      any
      Organic Change, appropriate provision shall be made by the Company with respect
      to the rights and interests of the Holder of this Warrant to the end that the
      provisions hereof (including, without limitation, provisions for adjustments
      of
      the Exercise Price and of the number of shares purchasable and receivable upon
      the exercise of this Warrant) shall thereafter be applicable, in relation to
      any
      shares of stock, securities or assets thereafter deliverable upon the exercise
      hereof. The Company will not effect any such consolidation, merger or sale
      unless, prior to the consummation thereof, the successor corporation (if other
      than the Company) resulting from such consolidation or merger
      or
the
      corporation purchasing such assets shall assume by written instrument reasonably
      satisfactory in form and substance to the Holder executed and mailed or
      delivered to the registered Holder hereof at the last address of such Holder
      appearing on the books of the Company, the obligation to deliver to such Holder
      such shares of stock, securities or assets as, in accordance
      with the foregoing provisions, such Holder may be entitled to
      purchase. If
      there
      is an Organic Change, then the Company shall cause to be mailed to the Holder
      at
      its last address as it shall appear on the books and records of the Company,
      at
      least 10 calendar days before the effective date of the Organic Change, a notice
      stating the date on which such Organic Change is expected to become effective
      or
      close, and the date as of which it is expected that holders of the Common Stock
      of record shall be entitled to exchange their shares for securities, cash,
      or
      other property delivered upon such Organic Change; provided,
      that
      the failure to mail such notice or any defect therein or in the mailing thereof
      shall not affect the validity of the corporate action required to be specified
      in such notice. The Holder is entitled to exercise this Warrant during the
      10-day period commencing on the date of such notice to the effective date of
      the
      event triggering such notice. In
      any
      event, the successor corporation (if other than the Company) resulting from
      such
      consolidation or merger or the corporation purchasing such assets shall be
      deemed to assume such obligation to deliver to such Holder such shares of stock,
      securities or assets even in the absence of a written instrument assuming such
      obligation to the extent such assumption occurs by operation of law.

    (b)   
       Certificate
      as to Adjustments.
      Upon
      the occurrence of each adjustment or readjustment pursuant to this Section
      3,
      the Company at its expense shall promptly compute such adjustment or
      readjustment in accordance with the terms hereof and furnish to each Holder
      of
      this Warrant a certificate setting forth such adjustment or readjustment and
      showing in detail the facts upon which such adjustment or readjustment is based.
      The Company shall
      promptly furnish
      or cause to be furnished to such Holder a like certificate setting forth: (i)
      such adjustments and readjustments; and (ii) the number of shares and the
      amount, if any, of other property which at the time would be received upon
      the
      exercise of the Warrant.

    

    (c)   
       Certain
      Events.
      If any
      event occurs as to which the other provisions of this Section 3 are not strictly
      applicable but the lack of any adjustment would not fairly protect the purchase
      rights of the Holder under this Warrant in accordance with the basic intent
      and
      principles of such provisions, or if strictly applicable would not fairly
      protect the purchase rights of the Holder under this Warrant in accordance
      with
      the basic intent and principles of such provisions, then the Company's Board
      of
      Directors will, in good faith, make an appropriate adjustment to protect the
      rights of the Holder; provided,
      that no
      such adjustment pursuant to this Section 3(c) will increase the Exercise Price
      or decrease the number of Warrant Shares as otherwise determined pursuant to
      this Section 3.

    

    (d)   
       Adjustment
      of Exercise Price Upon Issuance of Additional Shares of Common
      Stock.
      In the
      event the Company shall at any time prior to the fifteen month anniversary
      of
      the Effective Date issue Additional Shares of Common Stock, as defined below,
      without consideration or for a consideration per share less than the Exercise
      Price in effect immediately prior to such issue, then the Exercise Price shall
      be reduced,
      concurrently with such issue, to a price (calculated to the nearest cent)
      determined by multiplying such Exercise Price by a fraction, (A) the numerator
      of which shall be (1) the number of shares of Common Stock outstanding
      immediately prior to such issue plus (2) the number of shares of Common Stock
      which the aggregate consideration received or to be received by the Company
      for
      the total number of Additional Shares of Common Stock so issued would purchase
      at such Exercise Price; and (B) the denominator of which shall be the number
      of
      shares of Common Stock outstanding immediately prior to such issue plus the
      number of such Additional Shares of Common Stock so issued;
      provided that, (i) for the purpose of this Section 3(d), all shares of Common
      Stock issuable upon conversion or exchange of convertible securities outstanding
      immediately prior to such issue shall be deemed to be outstanding, and (ii)
      the
      number of shares of Common Stock deemed issuable upon conversion or exchange
      of
      such outstanding convertible securities shall be determined without giving
      effect to any adjustments to the conversion or exchange price or conversion
      or
      exchange rate of such convertible securities resulting from the issuance of
      Additional Shares of Common Stock that is the subject of this calculation.
      For
      purposes of this Warrant, “Additional Shares of Common Stock” shall mean all
      shares of Common Stock issued by the Company after the Effective Date (including
      without limitation any shares of Common Stock issuable upon conversion or
      exchange of any convertible securities or upon exercise of any option or
      warrant, on an as-converted basis), other than: (i) shares of Common Stock
      issued or issuable upon conversion or exchange of any convertible securities
      or
      exercise of any options or warrants outstanding on the Effective Date; (ii)
      shares of Common Stock issued or issuable by reason of a dividend, stock split,
      split-up or other distribution on shares of Common Stock that is covered by
      Sections 3(a)(i) through 3(a)(iii) above; (iii) shares of Common Stock (or
      options with respect thereto) issued or issuable to employees or directors
      of,
      or consultants to, the Company or any of its subsidiaries pursuant to a plan,
      agreement or arrangement approved by the Board of Directors of the Company;
      or
      (iv) shares of Common Stock issued or issuable pursuant to acquisitions or
      strategic transactions. The provisions of this Section 3(d) shall not operate
      to
      increase the Exercise Price.

      the
      number of Warrant Shares which may then be purchased hereunder, each of such
      new
      Warrants to be dated the date of such exchange and to represent the right to
      purchase such number of Warrant Shares as shall be designated by the Holder.
      The
      Holder shall surrender this Warrant with duly executed instructions regarding
      such
      re-certification of this Warrant to the Secretary of the Company at its

      equivalent number of Warrant Shares; provided,
      that,
      as a prerequisite to the issuance of a substitute Warrant, the Company may
      require satisfactory evidence of loss, theft or destruction as well as an
      indemnity from the Holder of a lost, stolen or destroyed Warrant.

    

    6.     PAYMENT
      OF TAXES

      applicable law or regulation. Without limiting the generality of the foregoing,
      the Company covenants that it will use commercially reasonable efforts to take

      the
      exercise of this Warrant and use commercially reasonable efforts to obtain
      all
      such authorizations, exemptions or consents, including but not limited to
      consents from the Company’s stockholders or Board of Directors or any public
      regulatory body, as may be necessary to enable the Company to perform its
      obligations under this Warrant.

    

    18.   NO
      THIRD
PARTY
      RIGHTS

    

    This
      Warrant is
      not

      beneficiary hereunder.

      AGREEMENT

     

    This
      Escrow Agreement (this “Agreement”) is entered into as of May 31, 2007, by and
      among WaferGen Bio-systems, Inc., formerly known as La Burbuja Café, Inc., a
      Nevada corporation (the “Parent”), Alnoor Shivji (the “Indemnification
      Representative”) and Gottbetter & Partners, LLP (the “Escrow
      Agent”).

     

    WHEREAS,
      the Parent has entered into an Agreement and Plan of Merger and Reorganization
      (the “Merger Agreement”) with WaferGen, Inc., a Delaware corporation (the
“Company”), (i) pursuant to which a wholly-owned subsidiary of the Parent will
      merge with and into the Company, with the Company surviving the merger and
      (ii)
      as a result of which the Company will become a wholly-owned subsidiary of the
      Parent;

     

    WHEREAS,
      the Merger Agreement provides that an escrow account will be established to
      secure the indemnification obligations of the stockholders of the Company as
      of
      the Closing Date, as such term is defined in the Merger Agreement (collectively,
      the “Indemnifying Stockholders”), to the Parent; and

     

    WHEREAS,
      the parties hereto desire to establish the terms and conditions pursuant to
      which such escrow account will be established and maintained.

     

    NOW,
      THEREFORE, the parties hereto hereby agree as follows:

     

    1. Consent
      of Company Stockholders.
      The
      Indemnifying Stockholders have, either by virtue of their approval of the Merger
      Agreement or through the execution of an instrument to such effect, consented
      to: (a) the establishment of this escrow to secure the Indemnifying
      Stockholders’ indemnification obligations under Article 6 of the Merger
      Agreement in the manner set forth herein, (b) the appointment of the
      Indemnification Representative as their representative for purposes of this
      Agreement and as attorney-in-fact and agent for and on behalf of each
      Indemnifying Stockholder, and the taking by the Indemnification Representative
      of any and all actions and the making of any decisions required or permitted
      to
      be taken or made by him under this Agreement and (c) all of the other
      terms, conditions and limitations in this Agreement.

     

    2. Escrow
      and Indemnification.

     

    (a) Escrow
      of Shares.
      Simultaneously with the execution of this Agreement, the Parent shall deposit
      with the Escrow Agent certificates representing an aggregate of 410,726 shares
      of common stock of the Parent, as determined pursuant to Section 1.5(b) of
      the Merger Agreement, or such other number as adjusted pursuant to Section
      1.8(e) of the Merger Agreement issued in the name of the Escrow Agent or its
      nominee. The Escrow Agent hereby acknowledges receipt of such stock
      certificates. The shares deposited with the Escrow Agent pursuant to the first
      sentence of this Section 2(a) are referred to herein as the “Escrow
      Shares.” The Escrow Shares shall be held as a trust fund and shall not be
      subject to any lien, attachment, trustee process or any other judicial process
      of any creditor of any party hereto. The Escrow Agent agrees to hold the Escrow
      Shares in an escrow account (the “Escrow Account”), subject to the terms and
      conditions of this Agreement.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    (b) Indemnification.
      The
      Indemnifying Stockholders have agreed in Section 6.1 of the Merger Agreement
      to
      indemnify and hold harmless the Parent from and against certain Damages (as
      defined in Section 6.1 of the Merger Agreement). The Escrow Shares shall be
      (i)
      security for such indemnity obligation of the Indemnifying Stockholders, subject
      to the limitations, and in the manner provided, in this Agreement and the Merger
      Agreement and (ii) shall be the exclusive means for the Parent to collect any
      Damages with respect to which the Parent is entitled to indemnification under
      Article VI of the Merger Agreement.

     

    (c) Dividends,
      Etc.
      Any
      securities distributed in respect of or in exchange for any of the Escrow
      Shares, whether by way of stock dividends, stock splits or otherwise, shall
      be
      issued in the name of the Escrow Agent or its nominee and shall be delivered
      to
      the Escrow Agent, who shall hold such securities in the Escrow Account. Such
      securities shall be considered Escrow Shares for purposes hereof. Any cash
      dividends or property (other than securities) distributed in respect of the
      Escrow Shares shall promptly be distributed by the Escrow Agent to the
      Indemnifying Stockholders in accordance with Section 3(c).

     

    (d) Voting
      of Shares.
      The
      Indemnification Representative shall have the right, in his sole discretion,
      on
      behalf of the Indemnifying Stockholders, to direct the Escrow Agent in writing
      as to the exercise of any voting rights pertaining to the Escrow Shares, and
      the
      Escrow Agent shall comply with any such written instructions. In the absence
      of
      such instructions, the Escrow Agent shall not vote any of the Escrow Shares.
      The
      Indemnification Representative shall have no obligation to solicit consents
      or
      proxies from the Indemnifying Stockholders for purposes of any such
      vote.

     

    (e) Transferability.
      The
      respective interests of the Indemnifying Stockholders in the Escrow Shares
      shall
      not be assignable or transferable, other than by operation of law. Notice of
      any
      such assignment or transfer by operation of law shall be given to the Escrow
      Agent and the Parent, and no such assignment or transfer shall be valid until
      such notice is given.

     

    3. Distribution
      of Escrow Shares.

     

    (a) The
      Escrow Agent shall distribute the Escrow Shares only in accordance with (i)
      a
      written instrument delivered to the Escrow Agent that is executed by both the
      Parent and the Indemnification Representative and that instructs the Escrow
      Agent as to the distribution of some or all of the Escrow Shares, (ii) an
      order of a court of competent jurisdiction, a copy of which is delivered to
      the
      Escrow Agent by either the Parent or the Indemnification Representative, that
      instructs the Escrow Agent as to the distribution of some or all of the Escrow
      Shares, or (iii) the provisions of Section 3(b) hereof.

     

    (b) Within
      five business days after May 31, 2009 (the “Termination Date”), the Escrow Agent
      shall distribute to the Indemnifying Stockholders all of the Escrow Shares
      then
      held in escrow, registered in the names of the Indemnifying Stockholders.
      Notwithstanding the foregoing, if the Parent has previously delivered to the
      Escrow Agent a copy of a Claim Notice (as hereinafter defined) and the Escrow
      Agent has not received written notice of the resolution of the claim covered
      thereby, or if the Parent has previously delivered to the Escrow Agent a copy
      of
      an Expected Claim Notice (as hereinafter defined) and the Escrow Agent has
      not
      received written notice of the resolution of the anticipated claim covered
      thereby, the Escrow Agent shall retain in escrow after the Termination Date
      such
      number of Escrow Shares as have a Value (as defined in Section 4 below)
      equal to the Claimed Amount (as hereinafter defined) covered by such Claim
      Notice or equal to the estimated amount of Damages set forth in such Expected
      Claim Notice, as the case may be. Any Escrow Shares so retained in escrow shall
      be distributed only in accordance with the terms of clauses (i) or (ii) of
      Section 3(a) hereof. For purposes of this Agreement, a Claim Notice means a
      written notification under the Merger Agreement given by the Parent to the
      Indemnifying Stockholders which contains (i) a description and the amount (the
      “Claimed Amount”) of any Damages incurred or reasonably expected to be incurred
      by the Parent, (ii) a statement that the Parent is entitled to indemnification
      under Article 6 of the Merger Agreement for such Damages and a reasonable
      explanation of the basis therefor, and (iii) a demand for payment (in the manner
      provided in Section 9.7 of the Merger Agreement) in the amount of such Damages.
      For purposes of this Agreement, an Expected Claim Notice means a notice
      delivered pursuant to the Merger Agreement by the Parent to an Indemnifying
      Stockholder, before expiration of a representation or warranty, to the effect
      that, as a result a legal proceeding instituted by or written claim made by
      a
      third party, the Parent reasonably expects to incur Damages as a result of
      a
      breach of such representation or warranty .

    (c) Any
      distribution of all or a portion of the Escrow Shares (or cash or other property
      pursuant to Section 2(c)) to the Indemnifying Stockholders shall be made by
      delivery of stock certificates issued in the name of the Indemnifying
      Stockholders (or cash or other property), covering such percentage of the Escrow
      Shares (or cash or other property) being distributed as is calculated in
      accordance with the percentages set forth opposite such holders’ respective
      names on Attachment A
      attached
      hereto
      provided,
      however,
      that
      the Escrow Agent shall withhold the distribution of the portion of the Escrow
      Shares otherwise distributable to an Indemnifying Stockholder who has not,
      according to a written notice provided by the Parent to the Escrow Agent, prior
      to such distribution, surrendered pursuant to the terms of the Merger Agreement
      his, her or its documents formerly representing equity interests of the Company.
      Any such withheld shares shall be delivered to the Parent promptly after the
      Termination Date, and shall be delivered by the Parent to the Indemnifying
      Stockholders to whom such shares would have otherwise been distributed upon
      surrender of documents evidencing their Company equity interests. Distributions
      to the Indemnifying Stockholders shall be made by mailing stock certificates
      to
      such holders at their respective addresses shown on Attachment A
      (or such
      other address as may be provided in writing to the Escrow Agent by any such
      holder). No fractional Escrow Shares shall be distributed to Indemnifying
      Stockholders pursuant to this Agreement. Instead, the number of shares that
      each
      Indemnifying Stockholder shall receive shall be rounded up or down to the
      nearest whole number (provided that the Indemnification Representative shall
      have the authority to effect such rounding in such a manner that the total
      number of whole Escrow Shares to be distributed equals the number of Escrow
      Shares then held in the Escrow Account).

     

    4. Valuation
      of Escrow Shares.
      For
      purposes of this Agreement, the “Value” of any Escrow Shares shall be $1.50 per
      share, multiplied by the number of such Escrow Shares.

     

    5. Fees
      and Expenses of Escrow Agent.
      The
      Parent, on the one hand, and the Indemnifying Stockholders, on the other hand,
      shall each pay one-half of the fees of the Escrow Agent for the services to
      be
      rendered by the Escrow Agent hereunder.

    6. Limitation
      of Escrow Agent’s Liability.

     

    (a) The
      Escrow Agent shall incur no liability with respect to any action taken or
      suffered by it in reliance upon any notice, direction, instruction, consent,
      statement or other documents believed by it to be genuine and duly authorized,
      nor for other action or inaction except its own willful misconduct or gross
      negligence. The Escrow Agent shall not be responsible for the validity or
      sufficiency of this Agreement. In all questions arising under the Escrow
      Agreement, the Escrow Agent may rely on the advice of counsel, and the Escrow
      Agent shall not be liable to anyone for anything done, omitted or suffered
      in
      good faith by the Escrow Agent based on such advice. The Escrow Agent shall
      not
      be required to take any action hereunder involving any expense unless the
      payment of such expense is made or provided for in a manner reasonably
      satisfactory to it. In no event shall the Escrow Agent be liable for indirect,
      punitive, special or consequential damages.

     

    (b) The
      Parent and the Indemnifying Stockholders agree to indemnify the Escrow Agent
      for, and hold it harmless against, any loss, liability or expense incurred
      without gross negligence or willful misconduct on the part of Escrow Agent,
      arising out of or in connection with its carrying out of its duties hereunder.
      The Parent, on the one hand, and the Indemnifying Stockholders, on the other
      hand, shall each be liable for one-half of such amounts.

     

    7. Liability
      and Authority of Indemnification Representative; Successors and
      Assignees.

     

    (a) The
      Indemnification Representative shall not incur any liability to the Indemnifying
      Stockholders with respect to any action taken or suffered by him in reliance
      upon any note, direction, instruction, consent, statement or other documents
      believed by him to be genuinely and duly authorized, nor for other action or
      inaction except his own willful misconduct or gross negligence. The
      Indemnification Representative may, in all questions arising under the Escrow
      Agreement, rely on the advice of counsel and the Indemnification Representative
      shall not be liable to the the Indemnifying Stockholders for anything done,
      omitted or suffered in good faith by the Indemnification Representative based
      on
      such advice.

     

    (b) In
      the
      event of the death or permanent disability of the Indemnification
      Representative, or his or her resignation as an Indemnification Representative,
      a successor Indemnification Representative shall be appointed by the other
      Indemnification Representative or, absent its appointment, a successor
      Indemnification Representative shall be elected by a majority vote of the
      Indemnifying Stockholders, with each such Indemnifying Stockholder (or his,
      her
      or its successors or assigns) to be given a vote equal to the number of votes
      represented by the shares of stock of the Company held by such Indemnifying
      Stockholder immediately prior to the effective time of the share purchase under
      the Merger Agreement. Each successor Indemnification Representative shall have
      all of the power, authority, rights and privileges conferred by this Agreement
      upon the original Indemnification Representative, and the term “Indemnification
      Representative” as used herein shall be deemed to include each successor
      Indemnification Representative.

     

    (c) The
      Indemnification Representative shall have full power and authority to represent
      the Indemnifying Stockholders, and their successors, with respect to all matters
      arising under this Agreement and Article 6 of the Merger Agreement and all
      actions taken by the Indemnification Representative hereunder or under Article 6
      of the Merger Agreement shall be binding upon the Indemnifying Stockholders,
      and
      their successors, as if expressly confirmed and ratified in writing by each
      of
      them. Without limiting the generality of the foregoing, the Indemnification
      Representative shall have full power and authority to interpret all of the
      terms
      and provisions of this Agreement, to compromise any claims asserted hereunder
      and to authorize any release of the Escrow Shares to be made with respect
      thereto, on behalf of the Indemnifying Stockholders and their successors.

    (d) The
      Escrow Agent may rely on the Indemnification Representative as the exclusive
      agent of the Indemnifying Stockholders under this Agreement and shall incur
      no
      liability to any party with respect to any action taken or suffered by it in
      good faith reliance thereon.

     

    8. Amounts
      Payable by Indemnifying Stockholders.
      The
      amounts payable by the Indemnifying Stockholders under this Agreement (i.e.,
      the
      fees of the Escrow Agent payable pursuant to Section 5 and the
      indemnification obligations pursuant to Section 6(b)) shall be payable
      solely as follows. The Escrow Agent shall notify the Indemnification
      Representative of any such amount payable by the Indemnifying Stockholders
      as
      soon as it becomes aware that any such amount is payable, with a copy of such
      notice to the Parent. On the sixth business day after the delivery of such
      notice, the Escrow Agent shall sell such number of Escrow Shares (up to the
      number of Escrow Shares then available in the Escrow Account), subject to
      compliance with all applicable securities laws, as is necessary to raise such
      amount, and shall be entitled to apply the proceeds of such sale in satisfaction

    Any
      party
      may give any notice, instruction or communication in connection with this
      Agreement using any other means (including personal delivery, telecopy or
      ordinary mail), but no such notice, instruction or communication shall be deemed
      to have been delivered unless and until it is actually received by the party
      to
      whom it was sent. Any party may change the address to which notices,
      instructions or communications are to be delivered by giving the other parties
      to this Agreement notice thereof in the manner set forth in this
      Section 10.

     

    11. Successor
      Escrow Agent.
      In the
      event the Escrow Agent becomes unavailable or unwilling to continue in its
      capacity herewith, the Escrow Agent may resign and be discharged from its duties
      or obligations hereunder by delivering a resignation to the parties to this
      Escrow Agreement, not less than 60 days prior to the date when such
      resignation shall take effect. The Parent may appoint a successor Escrow Agent
      without the consent of the Indemnification Representative so long as such
      successor is a bank with assets of at least $500 million, and may appoint any
      other successor Escrow Agent with the consent of the Indemnification
      Representative, which shall not be unreasonably withheld. If, within such notice
      period, the Parent provides to the Escrow Agent written instructions with
      respect to the appointment of a successor Escrow Agent and directions for the
      transfer of any Escrow Shares then held by the Escrow Agent to such successor,
      the Escrow Agent shall act in accordance with such instructions and promptly
      transfer such Escrow Shares to such designated successor. If no successor Escrow
      Agent is named as provided in this Section 11 prior to the date on which the
      resignation of the Escrow Agent is to properly take effect, the Escrow Agent
      may
      apply to a court of competent jurisdiction for appointment of a successor Escrow
      Agent.

      of
      this Agreement shall be effective unless in writing. No waiver by any party
      of
      any such condition or breach, in any one instance, shall be deemed to be a
      further or continuing waiver of any such condition or breach or a waiver of
      any
      other condition or breach of any other provision contained herein.

      State of New York in connection with any actions or proceedings brought against
      any party hereto by the Escrow Agent arising out of or relating to this Escrow
      Agreement. In any such action or proceeding, the parties hereby absolutely
      and
      irrevocably waive personal service of any summons, complaint, declaration or
      other process and hereby absolutely and irrevocably agree that the service
      thereof may be made by certified or registered first-class mail directed to
      such
      party, at their respective addresses in accordance with Section 10
      hereof.
