      adjustment as provided in Section 8 herein (individually, a “Warrant

      severally, the “Warrant
      Units”).
      Each
      Warrant Unit shall provide the holder of such Unit with a capital account

      in the event the Merger does not occur, then the exercise price shall be $92.72
      per Unit, subject to any adjustments pursuant to Section 8. Notwithstanding
      the
      foregoing, the Exercise Price and number of Warrant Units purchasable pursuant
      to each Warrant are subject to adjustment as provided in Section 8.


     

    2.  EXERCISE
      OF WARRANT; EXPIRATION DATE.
      

     

    2.1  

     

    (a)  This
      Warrant is exercisable at any time and from time to time commencing on July
      23,
      2007 (“Commencement
      Date”)
      and
      ending at 5:00 p.m., Eastern Time on the date set forth above (the “Expiration
      Date”),
      in
      whole or from time to time in part, at the option of the Warrant Holder, upon
      surrender of this Warrant to the Company together with a duly completed Notice
      of Exercise in the form attached hereto and payment of an amount equal to the
      then applicable Exercise Price multiplied by the number of Warrant Units then
      being purchased upon such exercise, except as provided in Section 2.1(b)
      hereunder. 

    


    (b) If
      the
      securities underlying this Warrant are adjusted in accordance with Section
      8(b),
      into shares of common stock (“Common Stock”) and such Common Stock is
      subsequently registered under Section 12 of the Securities Exchange Act of
      1934,
      as amended, the Warrant Holder may elect to pay all or part of the Exercise
      Price by surrendering shares of Common Stock to the Company, including by
      allowing the Company to deduct from the number of shares of Common Stock
      deliverable upon exercise of this Warrant, a number of such shares which has
      an
      aggregate Fair Market Value, determined as of the average of the last sale
      price
      (defined hereunder) of the Common Stock for the 20 consecutive trading days
      immediately preceding the date of exercise of this Warrant, equal to the
      aggregate Exercise Price. In the event that the Warrant Holder elects to utilize
      the “cashless exercise” procedure contained in Section 2.1(b), this Warrant is
      exercisable upon surrender of this Warrant to the Company together with a duly
      completed Notice of Exercise in the form attached hereto and surrender of that
      number of shares of Common Stock equal to the aggregate Exercise Price
      determined in accordance with this Section 2.1(b)(i) or (ii). “Fair Market
      Value” per share of Common Stock on any relevant date shall be determined in
      accordance with the following provisions:

    


    (i) If
      the
      Common Stock is at the time traded on the NASD OTC Bulletin Board or other
      electronic quotation service, then the Fair Market Value shall be the average
      of
      the last sale price per share of the Common Stock for the 20 consecutive trading
      days preceding the date of exercise of this Warrant; or

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    (ii) If
      the
      Common Stock is at the time listed on any Exchange, then the Fair Market Value
      shall be the average of the last sale price per share of the Common Stock for
      the 20 consecutive trading days preceding the date of exercise of this Warrant,
      on the Exchange determined to be the primary market for the Common Stock.
      "Exchange" shall mean any organization, association, or group of persons,
      whether incorporated or unincorporated, which constitutes, maintains, or
      provides a market place or facilities for bringing together purchasers and
      sellers of securities or for otherwise performing with respect to securities
      the
      functions commonly performed by a stock exchange as that term is generally
      understood, and includes the market place and the market facilities maintained
      by such exchange.


     

    2.2  Each
      exercise of this Warrant shall be deemed to have been effected immediately
      prior
      to the close of business on the day on which this Warrant shall have been
      surrendered to the Company as provided in Section 2.1. At such time, the person
      or persons in whose name or names any certificates for Warrant Units shall
      be
      issuable upon such exercise as provided in Section 2.3 below shall be deemed
      to
      have become the holder or holders of record of the Warrant Units represented
      by
      such certificates.

     

    2.3  Within
      three business days after the exercise of the purchase right represented by
      this
      Warrant, the Company at its expense will use its reasonable best efforts to
      cause to be issued in the name of, and delivered to, the Warrant Holder, or,
      subject to the terms and conditions hereof, to such other individual or entity
      as such Warrant Holder (upon payment by such Warrant Holder of any applicable
      transfer taxes) may direct: 

     

    (a)  a
      certificate or certificates for the number of full Warrant Units to which such
      Warrant Holder shall be entitled upon such exercise , and 

     

    (b)  in
      case
      such exercise is in part only, a new Warrant or Warrants (dated the date hereof)
      of like tenor, stating on the face or faces thereof the number of Units
      currently stated on the face of this Warrant minus the number of such Units
      purchased by the Warrant Holder upon such exercise as provided in Section 2.2
      (in each case prior to any adjustments made thereto pursuant to the provisions
      of this Warrant).

     

    3.  REGISTRATION
      AND TRANSFER ON COMPANY BOOKS.
      

     

    3.1  The
      Company (or an agent of the Company) will maintain a register containing the
      names and addresses of the Warrant Holders. Any Warrant Holder may change its,
      his or her address as shown on the warrant register by written notice to the
      Company requesting such change. 

     

    3.2  The
      Company shall register upon its books any transfer of a Warrant upon surrender
      of same as provided in Section 5. 

     

    4.  RESERVATION
      OF UNITS.
      The
      Company will at all times reserve and keep available, solely for issuance and
      delivery upon the exercise of this Warrant, such Warrant Units and other stock,
      securities and property, as from time to time shall be issuable upon the
      exercise of this Warrant. As
      long as the Warrant shall be outstanding, the Company shall use its commercially
      reasonable efforts to cause all Warrant Units issuable upon exercise of the
      Warrants to be listed (subject to official notice of issuance) on each Exchange
      (or, if applicable on Nasdaq, NASD OTC Bulletin Board or Pink Sheets, LLC or
      any
      successor electronic quotation service and trading market) on which the
      Company's Membership Interests are then listed and/or quoted, if
      any.

    5.  EXCHANGE,
      TRANSFER, ASSIGNMENT OR LOSS OR MUTILATION OF WARRANTS.
      This Warrant is exchangeable, without expense, at the option of the Warrant
      Holder, upon presentation and surrender hereof to the Company for other warrants
      of different denominations entitling the holder thereof to purchase in the
      aggregate the same number of Units purchasable hereunder. Subject to the terms
      of Sections 6 and 7, upon surrender of this Warrant to the Company at its
      principal office or at the office of its transfer agent, if any, with the
      Assignment Form annexed hereto duly executed and funds sufficient to pay any
      transfer tax, the Company shall, without charge, execute and deliver a new
      Warrant in the name of the assignee named in such instrument of assignment
      and
      this Warrant shall be promptly canceled. Subject to the terms of Sections 6
      and
      7, this Warrant may be divided or combined with other warrants which carry
      the
      same rights upon presentation hereof at the principal office of the Company
      together with a written notice specifying the names and denominations in which
      new Warrants are to be issued and signed by the Warrant Holder hereof. The
      term
“Warrant” as used herein includes any Warrants into which this Warrant may be
      divided or exchanged. Upon receipt by the Company of reasonable evidence of
      the
      ownership of and the loss, theft, destruction or mutilation of this Warrant
      and,
      in the case of loss, theft or destruction, of indemnity reasonably satisfactory
      to the Company, or, in the case of mutilation, upon surrender and cancellation
      of the mutilated Warrant, the Company shall execute and deliver in lieu thereof
      a new Warrant of like tenor and date representing an equal number of Warrants.
      

     

    6.  LIMITATION
      ON EXERCISE AND SALES.
      

     

    (a)
       Each
      holder of this Warrant acknowledges that this Warrant and the Warrant Units
      have
      not been registered under the Securities Act, as of the date of issuance hereof.
      This Warrant only may be transferred in compliance with this Section 6 and
      Section 7. The Company shall be under no obligation to issue the Units covered
      by such exercise unless and until the Warrant Holder shall have executed the
      form of exercise annexed hereto that states that at the time of such exercise
      that it is then an “accredited investor” within the meaning of Rule 501 of
      Regulation D, is acquiring such Units for its own account, and will not transfer
      the Warrant Units unless pursuant to an effective and current registration
      statement under the Securities Act or an exemption from the registration
      requirements of the Securities Act and any other applicable restrictions, in
      which event the Warrant Holder shall be bound by the provisions of a legend
      or
      legends to such effect that shall be endorsed upon the certificate(s)
      representing the Warrant Units issued pursuant to such exercise. In such event,
      the Warrant Units issued upon exercise hereof shall be imprinted with a legend
      in substantially the form provided in Section 7(b). 

    


    (b) Warrant
      Holder represents and warrants that it is acquiring this Warrant for its own
      account, for purposes of investment, and not with a view to, or for sale in
      connection with, any distribution thereof within the meaning of the Securities
      Act and the rules and regulations promulgated thereunder. Warrant Holder
      represents, warrants and agrees that it will not sell, exercise, transfer or
      otherwise dispose of this Warrant (or any interest therein) or any of the Units
      purchasable upon exercise hereof, except pursuant to (i) an effective
      registration statement under the Securities Act and applicable state securities
      laws or (ii) an opinion of counsel, satisfactory to Company, that an exemption
      from registration under the Securities Act and such laws is available. Warrant
      Holder further acknowledges and agrees that Company is not required, legally
      or
      contractually, so to register or qualify the Warrant or such Units or to take
      any action to make such an exemption available. Warrant Holder understands
      that
      Company will be relying upon the truth and accuracy of the representations
      and
      warranties contained in this Section 6 in issuing this Warrant and such Units
      without first registering the issuance thereof under the Securities Act or
      qualifying or registering the issuance thereof under any state securities laws
      that may be applicable.

    (c) Warrant
      Holder acknowledges that (i) there is not now, and there may not be in the
      future, any public market for the Warrant, (ii) although there currently is
      not
      a public trading market for the Units, there can be no assurance that any such
      market will be created and sustained, and (iii) there can be no assurance that
      Warrant Holder will be able to liquidate its investment in Company. Warrant
      Holder represents and warrants that it is familiar with and understands the
      terms and conditions of Rule 144 promulgated under the Securities
      Act.

    


    (d)
       Warrant
      Holder represents and warrants to Company that (i) it has such knowledge and
      experience in financial and business matters as is necessary to enable it to
      evaluate the merits and risks of any investments in Company and is not utilizing
      any other person to be a purchaser representative in connection with evaluation
      of such merits and risks; and (ii) it has no need for liquidity in an investment
      in Company and is able to bear the risk of that investment for an indefinite
      period and to afford a complete loss thereof.

    


    (e) Warrant
      Holder represents and warrants that it has had access to, and has been furnished
      with, all of the information it has requested from Company and has had an
      opportunity to review the books and records of Company and to discuss with
      management and members of the board of directors of Company the business and
      financial affairs of Company.

    


    (f)
       Warrant
      Holder agrees that at the time of each exercise of this Warrant, unless the
      issuance of Units issuable thereupon is pursuant to an effective registration
      statement under the Securities Act and under applicable state blue sky laws,
      Warrant Holder will provide Company with a letter embodying the representations
      and warranties set forth in subsections (b) through (e), in form and substance
      reasonably satisfactory to Company, and agrees that the certificate(s)
      representing any shares issued to it upon any exercise of this Warrant may
      bear
      such restrictive legend as Company may deem necessary to reflect the restricted
      status of such shares under the Securities Act unless Company shall have
      received from Warrant Holder an opinion of counsel to Warrant Holder, reasonably
      satisfactory in form and substance to Company and its counsel, that such
      restrictive legend is not required.

     

    7.  TRANSFER
      RESTRICTIONS.

    (a) If,
      at the time
      of the surrender of this Warrant in connection with any transfer of this
      Warrant, the transfer of this Warrant shall not be registered pursuant to an
      effective registration
      statement under the Securities Act
      and under
      applicable state securities or blue sky laws, the Company may require, as a
      condition of allowing such transfer (i) that the Warrant Holder or transferee
      of
      this Warrant, as the case may be, furnish to the Company a written opinion
      of
      counsel (which opinion shall be in form, substance and scope customary for
      opinions of counsel in comparable transactions and reasonably satisfactory
      to
      counsel for the Company) to the effect that such transfer may be made
      without
      registration under the
      Securities Act and under applicable state securities or blue sky laws, (ii)
      that
      the holder or transferee execute and deliver to the Company an investment letter
      in form and substance acceptable to the Company, (iii) that transferee agree
      in
      writing with the Company to be bound by the terms and conditions of this Warrant
      applicable to the Warrant Holder and (iv) that the transferee be an “accredited
      investor” as defined in Regulation D promulgated under the Securities
      Act.

     

    (b) The
      Units
      or other securities issuable on the exercise of the Warrant shall bear the
      following legend:

     

    THESE
      SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION,
      OR THE SECURITIES COMMISSION OF ANY STATE, IN RELIANCE UPON AN EXEMPTION FROM
      REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
      ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
      AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
      REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
      SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR
      TO
      SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE
      COMPANY.

     

    (c) The
      Holder acknowledges that the Warrant Units acquired upon the exercise of this
      Warrant, if not registered, will have restrictions upon resale imposed by state
      and federal securities laws.

     

    8.  ADJUSTMENT
      OF EXERCISE PRICE AND NUMBER OF UNITS DELIVERABLE.
      The
      Exercise Price and the number of Warrant Units purchasable pursuant to each
      Warrant shall be subject to adjustment from time to time as hereinafter set
      forth in this Section 8: 

     

    (a)  In
      case,
      prior to the expiration of this Warrant by exercise or by its terms, the Company
      shall issue any additional units of Membership Interest as a dividend or
      subdivide the number of outstanding Units into a greater number of units of
      Membership Interest, then in either of such cases, the then applicable Exercise
      Price per Warrant Unit purchasable pursuant to this Warrant in effect at the
      time of such action shall be proportionately reduced and the number of Warrant
      Units at that time purchasable pursuant to this Warrant shall be proportionately
      increased; and conversely, in the event the Company shall reduce the number
      of
      outstanding units of Membership Interest by combining such units into a smaller
      number of units of Membership Interest then, in such case, the then applicable
      Exercise Price per Warrant Unit purchasable pursuant to this Warrant in effect
      at the time of such action shall be proportionately increased and the number
      of
      Warrant Units at that time purchasable pursuant to this Warrant shall be
      proportionately decreased. If the Company shall, at any time during the life
      of
      this Warrant, declare a dividend payable in cash on its Membership Interest
      and
      shall at substantially the same time offer to its stockholders a right to
      purchase new units of Membership Interest from the proceeds of such dividend
      or
      for an amount substantially equal to the dividend, all units of Membership
      Interest so issued shall, for the purpose of this Warrant, be deemed to have
      been issued as a dividend. Any dividend paid or distributed upon the Membership
      Interests in units of any other class of securities convertible into units
      of
      Membership Interest shall be treated as a dividend paid in units of Membership
      Interest to the extent that units of Membership Interest are issuable upon
      conversion thereof.

     

    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

     

    (b)  In
      case,
      prior to the expiration of this Warrant by exercise or by its terms, the Company
      shall be recapitalized by reclassifying its outstanding units of Membership
      Interest, (or the Company or a successor corporation shall consolidate or merge
      with or convey all or substantially all of its or of any successor corporation’s
      property and assets to any other corporation or corporations (any such other
      corporations being included within the meaning of the term “successor
      corporation” hereinbefore used in the event of any consolidation or merger of
      any such other corporation with, or the sale of all or substantially all of
      the
      property of any such other corporation to, another corporation or corporations),
      then, as a condition of such recapitalization, consolidation, merger or
      conveyance, lawful and adequate provision shall be made whereby the holder
      of
      this Warrant shall thereafter have the right to purchase, upon the basis and
      on
      the terms and conditions specified in this Warrant, in lieu of the Warrant
      Units
      theretofore purchasable upon the exercise of this Warrant, such shares of stock,
      securities or assets, as may be issued or payable with respect to, or in
      exchange for, the number of Warrant Units theretofore purchasable upon the
      exercise of this Warrant had such recapitalization, consolidation, merger,
      or
      conveyance not taken place, and the exercise price for which shall have been
      appropriately adjusted to reflect the number of securities which the Warrant
      Holder is entitled to purchase in exchange for such Warrant; and in any such
      event, the rights of the Warrant Holder to any adjustment in the number of
      Warrant Units purchasable upon the exercise of this Warrant, as herein provided,
      shall continue and be preserved in respect of any stock which the Warrant Holder
      becomes entitled to purchase.

      liquidate, or wind up its affairs, lawful provision shall be made as part of
      the
      terms of any such sale, dissolution, liquidation or winding up, so that the
      holder of this Warrant may thereafter receive upon exercise hereof in lieu
      of
      each Warrant Unit that it would have been entitled to receive, the same kind
      and
      amount of any securities or assets as may be issuable, distributable or payable
      upon any such sale, dissolution, liquidation or winding up with respect to
      each
      Unit of the Company, provided, however, that in any case of any such sale or
      of
      dissolution, liquidation or winding up, the right to exercise this Warrant
      shall
      terminate on a date fixed by the Company; such date so fixed to be not earlier
      than 5:00 p.m., Eastern Time, on the forty-fifth day next succeeding the date
      on

      appears on the books of the Company.

    (c)  of
      the
      voluntary or involuntary dissolution, liquidation or winding-up of the Company,

      such
      other stock or securities) for securities or other property deliverable upon
      such reorganization, reclassification, consolidation, merger, transfer,
      dissolution, liquidation or winding-up. Such notice shall be mailed at least
      ten
      days prior to the record date or effective date for the event specified in
      such

      effective and current registration statement under the Securities Act or an
      exemption from the registration requirements of the Securities Act and any
      other
      applicable restrictions, in which event a legend or legends will be placed
      upon

    2. REGISTRATION
      RIGHTS.

     

    2.1 Demand
      Registration.

     

    2.1.1 Request
      for Registration. At any time and from time to time, the Holder or the permitted
      transferees of the Holder, may make a written demand for registration under
      the
      Securities Act (“Demanding Holder”) of all or part of their Registrable
      Securities (a “Demand Registration”). Any demand for a Demand Registration shall
      specify the number of shares of Registrable Securities proposed to be sold
      and
      the intended method(s) of distribution thereof. Upon any such request, the
      Demanding Holder shall be entitled to have their Registrable Securities included
      in the Demand Registration, subject to Section 2.2.2. The Company shall not
      be
      obligated to effect more than one (1) Demand Registration under this Section
      2.1.1 in respect of Registrable Securities.

     

    2.1.2 Effective
      Registration. A registration will not count as a Demand Registration until
      the
      Registration Statement filed with the Commission with respect to such Demand
      Registration has been declared effective and the Company has complied with
      all
      of its obligations under this Agreement with respect thereto; provided, however,
      that if, after such Registration Statement has been declared effective, the
      offering of Registrable Securities pursuant to a Demand Registration is
      interfered with by any stop order or injunction of the Commission or any other
      governmental agency or court, the Registration Statement with respect to such
      Demand Registration will be deemed not to have been declared effective, unless
      and until, (i) such stop order or injunction is removed, rescinded or otherwise
      terminated, and (ii) the Demanding Holder thereafter elects to continue the
      offering; provided, further, that the Company shall not be obligated to file
      a
      second Registration Statement until a Registration Statement that has been
      filed
      is counted as a Demand Registration or is terminated or withdrawn.

     

    
      
        
        

      

      
        15

        
          

        

      

      
        
        

      

    

    


    2.1.3 Withdrawal.
      If the Demanding Holder disapproves of the terms of any underwriting or is
      not
      entitled to include all of their Registrable Securities in any offering, such
      Demanding Holder may elect to withdraw from such offering by giving written
      notice to the Company and the underwriter(s) of their request to withdraw prior
      to the effectiveness of the Registration Statement filed with the Commission
      with respect to such Demand Registration. If the Demanding Holder withdraws
      from
      a proposed offering relating to a Demand Registration, then such registration
      shall not count as a Demand Registration provided for in Section
      2.1.1

     

    2.2
      Piggyback
      Registration.
      

     

    2.2.1
      At
      any
      time and from time to time during the Warrant exercise period, whenever the
      Company proposes to file a Registration Statement, the Company will prior to
      such filing give written notice to Holder of its intention to do so and, upon
      the written request of Holder given within ten (10) days after the Company
      provides such notice, the Company shall use its good faith efforts to cause
      all
      Registrable Securities which the Company has been requested by Holder to
      register to be registered under the Securities Act to the extent necessary
      to
      permit their sale or other disposition in accordance with the intended methods
      of distribution specified in the request of Holder; provided that the Company
      shall have the right to postpone or withdraw any registration effected pursuant
      to this Section 2 without obligation or liability to Holder. In the Holder’s
      request, the Holder will be required to describe briefly its proposed
      disposition of the Registrable Securities. However, in connection with any
      registration under Section 2, the Holder’s Registrable Securities shall be
      junior and subordinate to any registration rights granted by the Company which
      are already outstanding, and any senior registration rights granted by the
      Company in the future. 

    


    2.2.2 In
      connection with any registration under Section 2 involving an underwritten
      offering of the Company’s securities, the Company shall not be required to
      include any Registrable Securities in such underwriting unless Holder accepts
      the terms of the underwriting as agreed upon between the Company and the
      underwriters selected by it, and then only in such quantity as will not, in
      the
      sole discretion of the underwriters, jeopardize the success of the offering
      by
      the Company. If in the sole discretion of the managing underwriter or
      underwriters the registration of all, or part of, the Registrable Securities
      which Holder has requested to be included would adversely affect such public
      offering, then the Company shall be required to include in the underwriting
      only
      that number of Registrable Securities, if any, which the managing underwriter
      or
      underwriters believe may be sold without causing such adverse effect. If the
      number of Registrable Securities to be included in the underwriting in
      accordance with the foregoing is less than the total number of shares which
      Holder has requested to be included, then Holder and each participant other
      than
      the Company in such underwriting shall participate in the underwriting pro
      rata
      based upon their total ownership of Registrable Securities. Any such limitation
      shall be imposed in such manner so as to avoid any diminution in the number
      of
      shares the Company may register for sale by giving first priority for the shares
      to be registered for issuance and sale by the Company and the underwriter,
      and
      by giving second priority for the shares to be registered for sale by any holder
      of Registrable Securities pursuant to the terms of this Agreement.

    2.2.3 In
      connection with any registration under Section 2 involving a selling stockholder
      registration statement or any other registration statement not involving an
      underwritten offering of the Company’s securities, the Company reserves the
      right to include only that number of Registrable Securities, if any, as it
      shall
      determine in its sole discretion, may be sold without jeopardizing the success
      of the offering or having an adverse effect on the offering. If the number
      of
      Registrable Securities to be included in the offering in accordance with the
      foregoing is less than the total number of shares which Holder has requested
      to
      be included, then Holder and each participant other than the Company in such
      offering shall participate in the offering pro rata based upon their total
      ownership of Registrable Securities. Any such limitation shall be imposed in
      such manner so as to avoid any diminution in the number of shares the Company
      may register for sale by giving first priority for the shares to be registered
      for issuance and sale by the Company, and by giving second priority for the
      shares to be registered for sale by any holder of Registrable Securities
      pursuant to the terms of this Agreement.

     

    2.2.4
       Withdrawal. Any
      holder of Registrable Securities may elect to withdraw such holder’s request for
      inclusion of Registrable Securities in any Piggy-Back Registration by giving
      written notice to the Company of such request to withdraw prior to the
      effectiveness of the Registration Statement. The Company may also elect to
      withdraw a registration statement at any time prior to the effectiveness of
      the
      Registration Statement. Notwithstanding any such withdrawal, the Company shall
      pay all expenses incurred by the holders of Registrable Securities in connection
      with such Piggy-Back Registration as provided in Section 4.

     

    3. REGISTRATION

      When
      the
      Company proposes to effect the registration of any of the Registrable Securities
      under the Securities Act, the Company shall: 

     

    3.1.1
      furnish
      to the Holder such number of copies of the Registration Statement and the
      Prospectus included therein (including each preliminary Prospectus) as the
      Holder reasonably may request to facilitate the public sale or disposition
      of
      the Registrable Securities covered by the Registration Statement;

     

    3.1.2
      use
      its
      commercially reasonable efforts to register or qualify the Holder’s Registrable
      Securities covered by the Registration Statement under the securities or “blue
      sky” laws of such jurisdictions within the United States as the Holder may
      reasonably request, provided, however, that the Company shall not for any such
      purpose be required to qualify generally to transact business as a foreign
      corporation in any jurisdiction where it is not so qualified or to consent
      to
      general service of process in any such jurisdiction; and

      including, without limitation, all registration and filing fees, printing

    5.
      INDEMNIFICATION.

     

    5.1
      In
      the
      event of a registration of the Registrable Securities, the Holder (subject
      to
      the provisions of Section 5.2) will indemnify and hold harmless the Company,
      and
      its officers, directors and each other person, if any, who controls the Company
      within the meaning of the Securities Act, against all losses, claims, damages
      or
      liabilities, joint or several, to which the Company or such persons may become
      subject under the Securities Act, the Exchange Act or otherwise, insofar as
      such
      losses, claims, damages or liabilities (or actions in respect thereof) arise
      out
      of or are based upon: (i) any untrue statement or alleged untrue statement
      of any material fact which was furnished in writing by the Holder to the Company
      expressly for use in (and such information is contained in) the Registration
      Statement under which such Registrable Securities were registered under the
      Securities Act pursuant to the Warrant, any preliminary Prospectus or final
      Prospectus contained therein, or any amendment or supplement thereof, or arise
      out of or are based upon the omission or alleged omission to state therein
      a
      material fact required to be stated therein or necessary to make the statements
      therein not misleading, and will reimburse the Company and each such person
      for
      any reasonable legal or other expenses incurred by them in connection with
      investigating or defending any such loss, claim, damage, liability or action,
      provided, however, that such Holder will be liable in any such case if and
      only
      to the extent that any such loss, claim, damage or liability arises out of
      or is
      based upon said Holder’s untrue statement or alleged untrue statement or
      omission or alleged omission so made in conformity with information furnished
      in
      writing to the Company by or on behalf of said Holder specifically for use
      in
      any such document, or (ii) in connection with a Holder’s sale of
      Registrable Securities, including without limitation alleged violations of
      Regulation M. Notwithstanding the provisions of this paragraph, no Holder shall
      be required to indemnify any person or entity in excess of the amount of the
      aggregate net proceeds received by said Holder in respect of Registrable
      Securities in connection with any such registration under the Securities
      Act.

     

    5.2
      Promptly
      after receipt by a party entitled to claim indemnification hereunder (an
“Indemnified Party”) of notice of the commencement of any action, such
      Indemnified Party shall, if a claim for indemnification in respect thereof
      is to
      be made against a party hereto obligated to indemnify such Indemnified Party
      (an
“Indemnifying Party”), notify the Indemnifying Party in writing thereof, but the
      omission so to notify the Indemnifying Party shall not relieve it from any
      liability which it may have to such Indemnified Party other than under this
      Section 5.2 and shall only relieve it from any liability which it may have
      to
      such Indemnified Party under this Section 5.2 if and to the extent the
      Indemnifying Party is prejudiced by such omission. In case any such action
      shall
      be brought against any Indemnified Party and it shall notify the Indemnifying
      Party of the commencement thereof, the Indemnifying Party shall be entitled
      to
      participate in and, to the extent it shall wish, to assume and undertake the
      defense thereof with counsel reasonably satisfactory to such Indemnified Party,
      and, after notice from the Indemnifying Party to such Indemnified Party of
      its
      election so to assume and undertake the defense thereof, the Indemnifying Party
      shall not be liable to such Indemnified Party under this Section 5.2 for any
      legal expenses subsequently incurred by such Indemnified Party in connection
      with the defense thereof; if the Indemnified Party retains its own counsel,
      then
      the Indemnified Party shall pay all fees, costs and expenses of such counsel,
      provided, however, that, if the defendants in any such action include both
      the
      Indemnified Party and the Indemnifying Party and if counsel shall have
      reasonably concluded that there may be reasonable defenses available to the
      Indemnified Party which are different from or additional to those available
      to
      the Indemnifying Party or if the interests of the Indemnified Party reasonably
      may be deemed to conflict with the interests of the Indemnifying Party in either
      case which would prohibit such counsel from representing both parties under
      applicable conflicts of interest rules of professional ethics, the Indemnified
      Party shall have the right to select one separate counsel and to assume such
      legal defenses and otherwise to participate in the defense of such action,
      with
      the reasonable expenses and fees of such separate counsel and other expenses
      related to such participation to be reimbursed by the Indemnifying Party as
      incurred. Neither party shall settle any proceeding for which indemnification
      is
      sought without the written consent of the other party, which shall not be
      unreasonably withheld.

    5.3
       Notwithstanding
      any provision herein to the contrary, each Holder shall be treated individually
      and separately from all other Holders under this Section 5, and will not become
      the subject of any obligation under this Section 5 as a result of any action,
      failure to act, statement, omission, or otherwise of any other Holder
      hereunder.
