      the
      basis of the representations, warranties and agreements of the Company herein
      contained, and subject to all the terms and conditions of this
      Agreement:

    

    (a) The
      Company hereby engages the Placement Agent, on a non-exclusive basis and so
      long
      as the Placement
      Agent is authorized to act as a selling agent of the Company for the Company's
      Units pursuant to Section 1
      hereof,
      to assist the Company in obtaining a senior credit facility for project
      financing as described in the Prospectus.

    

    (b) As

      1A, upon the execution
      and delivery of definitive and binding written agreements by the Company and
      the
      lender providing the senior
      credit facility, the Company shall pay to the Placement Agent in cash, on the
      date such definitive and binding written
      agreements are executed, by wire transfer of immediately available funds to
      an
      account or accounts designated
      by the Placement Agent, art amount equal to one and one-half percent (1.5%)
      of
      the amount of the senior credit
      facility received by the Company; provided, however, that notwithstanding the
      foregoing, the Placement Agent
      shall be entitled to compensation pursuant to this Section 1A(b) only if: (i)
      the Placement Agent received a bona
      fide
      offer to provide the senior credit facility from the lender providing the senior
      credit facility to the Company,
      the Placement Agent communicated such bona fide offer to provide the senior
      credit facility to the Company
      and the Company thereafter accepted such bona fide offer, and (ii) the
      definitive and binding written agreements
      between the Company and the lender providing the senior credit facility are
      executed and delivered not more
      than
      twelve, (12) months following the termination of the Placement Agent's
      engagement to assist the Company
      in obtaining a senior credit facility pursuant to Section 1A(a).

    

    (c) Offers
      to
      provide a senior credit facility may be solicited by the Placement Agent as
      agent for the Company
      at such times and in such amounts as the Placement Agent deems advisable. The
      Placement Agent shall communicate
      to the Company, orally or in writing, each reasonable offer to provide a senior
      credit facility received by
      it as
      agent of the Company. The Company shall have the sole right in its absolute
      discretion to accept or reject any
      such
      offer, in whole or in part. The Placement Agent shall have the right, in its
      discretion reasonably exercised, subject
      to giving prior notice to the Company, to reject any offer to provide a senior
      credit facility received by it, in whole
      or
      in part, and any such rejection shall not be deemed a breach of its agreement
      contained herein.

      4. Reference
        to and Effect on the Loan Agreement.

       

      (a) Except
        as
        expressly provided herein, the Loan Agreement and all of the other Loan
        Documents shall remain unmodified and continue in full force and effect and

        and
        delivery hereof, that on and as of the date hereof and after giving effect
        to
        this Amendment:

       

      (a) It
        has
        the requisite power and authority to execute, deliver and perform its
        obligations under this Amendment. This Amendment has been duly authorized
        by all
        necessary action of it. This Amendment constitutes the legal, valid and binding
        obligation of it, enforceable against it in accordance with its terms, subject
        to the effect of any applicable bankruptcy, insolvency, reorganization or
        similar law affecting creditors’ rights generally and general principles of
        equity;

       

      (b) The
        representations set forth in the Loan Agreement and in the Loan Documents

        upon an Event of Default, will represent a binding obligation of the Guarantor
        enforceable against it in accordance with its terms, and the Common Stock,

“this
        Loan Agreement,” “this Agreement”, “hereunder,” “hereof,” “herein” or words of
        like import shall mean and be a reference to the Loan Agreement as amended
        hereby. The term “Loan Documents” as defined in Section 1.53 of the Loan
        Agreement shall include (in addition to the Loan Documents described in the
        Loan
        Agreement) this Amendment and any other agreements, instruments or other
        documents executed in connection herewith.

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

      (b) The
        Agent’s failure, at any time or times hereafter, to require strict performance
        by the Borrower of any provision or term of the Loan Agreement, this Amendment
        or the other Loan Documents shall not waive, affect or diminish any right
        of the
        Lender hereafter to demand strict compliance and performance herewith or
        therewith. Any suspension or waiver by the Lender of a breach of this Amendment
        or any Event of Default under the Loan Agreement shall not, except as expressly
        set forth herein, suspend, waive or affect any other breach of this Amendment
        or
        any Event of Default under the Loan Agreement, whether the same is prior
        or
        subsequent thereto and whether of the same or of a different kind or character.
        None of the undertakings, agreements, warranties, covenants and representations
        of the Borrower or Guarantor contained in this Amendment, shall be deemed
        to
        have been suspended or waived by the Agent unless such suspension or waiver
        is:
        (i) in writing and signed by the Agent, and (ii) delivered to the Borrower
        or
        Guarantor. In no event shall the Agent’s execution and delivery of this
        Amendment establish a course of dealing among the Agent, Guarantor, Borrower
        or
        any other obligor or in any other way obligate the Agent to hereafter provide
        any amendments or waivers with respect to the Loan Agreement. The terms and
        provisions of this Amendment shall be limited precisely as written and shall
        not
        be deemed: (A) to be a consent to a modification (except as expressly provided
        herein) or waiver of any other term or condition of the Loan Agreement or
        of any
        other Loan Documents, or (B) to prejudice any right or remedy that the Agent
        may
        now have under or in connection with the Loan Agreement or any of the other
        Loan
        Documents.

       

      7. Successors
        and Assigns.This
        Amendment shall be binding upon and inure to the benefit of the Agent, the
        Lenders and each of the other parties hereto and their respective successors
        and
        assigns; provided,
        however,
        the
        Borrower may not assign this Amendment or any of the Borrower’s rights hereunder
        without the Agent’s prior written consent. Any prohibited assignment of this
        Amendment shall be absolutely null and void. This Amendment may only be amended
        or modified by a writing signed by the Agent, Lenders, Borrower and
        Guarantor.

       

      8. Severability.Wherever
        possible, each provision of this Amendment shall be interpreted in such a
        manner
        so as to be effective and valid under applicable law, but if any provision
        of
        this Amendment is held to be prohibited by or invalid under applicable law,
        such
        provision or provisions shall be ineffective only to the extent of such
        provision and invalidity, without invalidating the remainder of this
        Amendment.

       

      9. Governing
        Law.THIS
        AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE
        WITH
        THE LAWS OF THE STATE OF NEW YORK, THE LAWS OF WHICH THE BORROWER HEREBY
        EXPRESSLY ELECTS TO APPLY TO THIS AMENDMENT, WITHOUT GIVING EFFECT TO PROVISIONS
        FOR CHOICE OF LAW HEREUNDER. THE BORROWER AGREES THAT ANY ACTION OR PROCEEDING
        BROUGHT TO ENFORCE OR ARISING OUT OF THIS AMENDMENT SHALL BE COMMENCED IN
        ACCORDANCE WITH THE PROVISIONS OF THE LOAN AGREEMENT. 

       

      10. Counterparts;
        Facsimile or Other Electronic Transmission.This
        Agreement may be executed in counterparts and by facsimile or other electronic
        signatures, each of which when so executed, shall be deemed an original,
        but all
        of which shall constitute but one and the same instrument.

          hereby certifies that, for value received, [Lender] or its permitted registered

          stock, $0.001 par value (the “Common

          Share”
and
          all

          Shares”)
          at an
          exercise price per share equal to $0.01 (the “Exercise
          Price”),
          at
          any time and from time to time from and after the Trigger Date (as defined
          below) and through and including [FIVE YEARS FROM THE ORIGINAL ISSUE DATE]
          (the
“Expiration
          Date”),
          and
          subject to the following terms and conditions: 

        

        This
          Warrant is issued pursuant to that certain Loan and Security Agreement,
          dated
          August 22, 2008, as amended or restated from time to time, by and among
          the
          Company, HydroGen L.L.C., Federated Kaufmann Fund, a portfolio of Federated
          Equity Funds, as Agent for Federated Kaufmann Fund and Samsung C&T
          Corporation (the “Loan

          The
          Warrants and Warrant Shares shall be referred to herein collectively as
          the

        1.
           Definitions.
          In
          addition to the terms defined elsewhere in this Warrant, capitalized terms
          that
          are not otherwise defined herein have the meanings given to such terms
          in the
          Security and Loan Agreement. 

          

        2.  List
          of Warrant Holders.
          The
          Company shall register this Warrant, upon records to be maintained by the
          Company for that purpose (the “Warrant
          Register”),
          in
          the name of the record Holder (which shall include the initial Holder or,
          as the
          case may be, any registered assignee to which this Warrant is permissibly
          assigned hereunder from time to time). The Company may deem and treat the
          registered Holder of this Warrant as the absolute owner hereof for the
          purpose
          of any exercise hereof or any distribution to the Holder, and for all other
          purposes, absent actual notice to the contrary. 

         

        3.
           List
          of Transfers.
          

        

        (a) This
          Warrant is subject to the restrictions noted in the legend set forth on
          the
          first page of this Warrant.

        (b) The
          Company shall register any such transfer of all or any portion of this
          Warrant
          in the Warrant Register, upon (i) surrender of this Warrant, with the Form
          of
          Assignment attached hereto duly completed and signed, to the Company at
          its
          address specified in Section 13 hereof and (ii) if a registration statement
          is
          not effective, (x) delivery, at the request of the Company, of an opinion
          of
          counsel reasonably satisfactory to the Company, to the effect that the
          transfer
          of such portion of this Warrant may be made pursuant to an available exemption
          from the registration requirements of the Securities Act and all applicable
          state securities or blue sky laws and (y) delivery by the transferee of
          a
          written statement to the Company certifying that the transferee is an
“accredited investor” as defined in Rule 501(a) under the Securities Act and
          making the representations and certifications set forth below in Section
          3(c),
          to the Company at its address specified herein. Upon any such registration
          or
          transfer, a new Warrant to purchase Common Stock, in substantially the
          form of
          this Warrant (any such new Warrant, a “New
          Warrant”),
          evidencing the portion of this Warrant so transferred shall be issued to
          the
          transferee and a New Warrant evidencing the remaining portion of this Warrant
          not so transferred, if any, shall be issued to the transferring Holder.
          The
          acceptance of the New Warrant by the transferee thereof shall be deemed
          the
          acceptance by such transferee of all of the rights and obligations in respect
          of
          the New Warrant that the Holder has in respect of this Warrant. Notwithstanding
          the foregoing, to the extent a Holder desires to transfer this Warrant
          to a
          non-affiliate after the effectiveness of any registration statement filed
          by the
          Company to register for offer and sale the Warrant Shares, then such transferee
          shall not be entitled to the registration rights associated with the underlying
          Warrant Shares but shall be entitled to all other rights as a Holder hereunder,
          including the right to exercise this Warrant on a “cashless” exercise basis
          pursuant to Section 10(b) hereof.

        

        (c) Any
          transferee of the Warrant shall represent and warrant to the Company the
          following:

        

        (i)
          Investment
          Intent.
          Such
          transferee understands that the Securities are “restricted securities” and have
          not been registered under the Securities Act or any applicable state securities
          law and is acquiring the Securities and, upon exercise of the Warrant will
          acquire the Warrant Shares issuable upon exercise thereof, as principal
          for its
          own account for investment purposes only and not with a view to or for
          distributing or reselling such Securities or any part thereof, without
          prejudice, however, to such transferee's right, subject to the provisions
          of
          this Agreement, at all times to sell or otherwise dispose of all or any
          part of
          such Securities pursuant to an effective registration statement under the
          Securities Act or under an exemption from such registration and in compliance
          with applicable federal and state securities laws. Subject to the immediately
          preceding sentence, nothing contained herein shall be deemed a representation
          or
          warranty by such transferee to hold the Securities for any period of time.
          Such
          transferee is acquiring the Securities hereunder in the ordinary course
          of its
          business. Such transferee does not have any agreement, plan or understanding,
          directly or indirectly, with any Person to distribute any of the
          Securities. 

        

        (ii)
          Purchaser
          Status.
          At the
          time such transferee was offered the Securities, it was, and at the date
          hereof
          it is, and on each date on which it exercises the Warrants it will be,
          an
“accredited investor” as defined in Rule 501(a) under the Securities Act. Such
          transferee is not a registered broker-dealer under Section 15 of the Exchange
          Act.

         

        (iii)
          General
          Solicitation.
          Such
          transferee is not purchasing the Securities as a result of any advertisement,
          article, notice or other communication regarding the Securities published
          in any
          newspaper, magazine or similar media or broadcast over television or radio
          or
          presented at any seminar or any other general solicitation or general
          advertisement.

        

        

        4.
           Exercise
          and Duration of Warrants.
          

         

        (a)
           All
          or
          any part of this Warrant shall be exercisable by the registered Holder
          at any
          time and from time to time on or after the Trigger Date (as defined below)
          and
          through and including the Expiration Date. 

        

        (b)
           As
          used
          in this Agreement, the following term shall have the respective
          meaning:

        

        (i)
          “Trigger Date” shall mean the day following the occurrence and existence of
          an Event of Default (as defined in the Loan and Security Agreement) that
          is
          either not cured by the Borrower or Guarantor (as defined in the Loan and
          Security Agreement)  nor waived by the Lenders (as defined in the Loan and
          Security Agreement) within the applicable cure period. 

        

        
          
            
            

          

          
            -2-

            
              

            

          

          
            
            

          

        

        (c)
           At
          5:00
          p.m., New York City time, on the Expiration Date, the portion of this Warrant
          not exercised prior thereto shall be and become void and of no value and
          this
          Warrant shall be terminated and no longer outstanding. 

        

        (d) The
          Holder may exercise this Warrant by delivering to the Company (i) an exercise
          notice, in the form attached hereto (the “Exercise
          Notice”),
          completed and duly signed, together with the aggregate Exercise Price for
          the
          number of Warrant Shares to be issued pursuant to such exercise, and (ii)
          if
          such Holder is not utilizing the cashless exercise provisions set forth
          in this
          Warrant, payment of the Exercise Price for the number of Warrant Shares
          as to
          which this Warrant is being exercised, and the date such items are delivered
          to
          the Company (as determined in accordance with the notice provisions hereof)
          is
          an “Exercise
          Date.”
The
          delivery by (or on behalf of) the Holder of the Exercise Notice and the
          applicable Exercise Price shall be accompanied by a statement by the Holder
          certifying to the Company the representations and warranties contained
          in
          Section 3(c) hereof. The Holder shall not be required to deliver the original
          Warrant in order to effect an exercise hereunder. Execution and delivery
          of the
          Exercise 

        

        Notice
          shall have the same effect as cancellation of the original Warrant and
          issuance
          of a New Warrant evidencing the right to purchase the remaining number
          of
          Warrant Shares.

         

         5.
           Delivery
          of Warrant Shares.
          

         

        (a)
           Upon
          exercise of this Warrant, the Company shall promptly (but in no event later
          than
          three Trading Days after the Exercise Date) issue or cause to be issued
          and
          cause to be delivered to or upon the written order of the Holder and in
          such
          name or names as the Holder may designate (provided that, if a registration
          statement is not effective and the Holder directs the Company to deliver
          a
          certificate for the Warrant Shares in a name other than that of the Holder
          or an
          Affiliate of the Holder, it shall deliver to the Company on the Exercise
          Date an
          opinion of counsel reasonably satisfactory to the Company to the effect
          that the
          issuance of such Warrant Shares in such other name may be made pursuant
          to an
          available exemption from the registration requirements of the Securities
          Act and
          all applicable state securities or blue sky laws), a certificate for the
          Warrant
          Shares issuable upon such exercise, free of restrictive legends unless
          a
          registration statement covering the resale of the Warrant Shares and naming
          the
          Holder as a selling stockholder thereunder is not then effective or the
          Warrant
          Shares are not freely transferable pursuant to Rule 144 under the Securities
          Act. The Holder, or any Person permissibly so designated by the Holder
          to
          receive Warrant Shares, shall be deemed to have become the holder of record
          of
          such Warrant Shares as of the Exercise Date. 

         

        (b)
           If
          by the
          close of the third Trading Day after delivery of an Exercise Notice, the
          Company
          fails to deliver to the Holder a certificate representing the required
          number of
          Warrant Shares in the manner required pursuant to Section 5(a), and if
          after
          such third Trading Day and prior to the receipt of such Warrant Shares,
          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 the Warrant
          Shares
          which the Holder anticipated receiving upon such exercise (a “Buy-In”),
          then
          the Company shall, within three Trading Days after the Holder’s request and in
          the Holder’s sole discretion, either (1) pay in cash to the Holder 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 Warrant Shares) shall terminate or (2) promptly honor its obligation
          to
          deliver to the Holder a certificate or certificates representing such Warrant
          Shares 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 Warrant Shares,
          times
          (B) the closing bid price of a share of Common Stock on the date of the
          event
          giving rise to the Company’s obligation to deliver such certificate.

         

        
          
            
            

          

          
            -3-

            
              

            

          

          
            
            

          

        

        

        (c)
           To
          the
          extent permitted by law, the Company’s obligations to issue and deliver Warrant
          Shares in accordance with the terms hereof are absolute and unconditional,
          irrespective of any action or inaction by the Holder to enforce the same,
          any
          waiver or consent with respect to any provision hereof, the recovery of
          any
          judgment against any Person or any action to enforce the same, or any setoff,
          counterclaim, recoupment, limitation or termination, or any breach or alleged
          breach by the Holder or any other Person of any obligation to the Company
          or any
          violation or alleged violation of law by the Holder or any other Person,
          and
          irrespective of any other circumstance which might otherwise limit such
          obligation of the Company to the Holder in connection with the issuance
          of
          Warrant Shares. Nothing herein shall limit a Holder’s right to pursue any other
          remedies available to it hereunder, at law or in equity including, without
          limitation, a decree of specific performance and/or injunctive relief with
          respect to the Company’s failure to timely deliver certificates representing
          shares of Common Stock upon exercise of the Warrant as required pursuant
          to the
          terms hereof. 

        

        6.
           Charges,
          Taxes and Expenses.
          Issuance and delivery of certificates for shares of Common Stock upon exercise
          of this Warrant shall be made without charge to the Holder for any issue
          or
          transfer tax, withholding tax, transfer agent fee or other incidental tax
          or
          expense in respect of the issuance of such certificates, all of which taxes
          and
          expenses shall be paid by the Company; provided,
          however,
          that
          the Company shall not be required to pay any tax which may be payable in
          respect
          of any transfer involved in the registration of any certificates for Warrant
          Shares or Warrants in a name other than that of the Holder. The Holder
          shall be
          responsible for all other tax liability that may arise as a result of holding
          or
          transferring this Warrant or receiving Warrant Shares upon exercise hereof.
          

         

        7.
           Replacement
          of Warrant.
          If this
          Warrant is mutilated, lost, stolen or destroyed, the Company shall issue
          or
          cause to be issued in exchange and substitution for and upon cancellation
          hereof, or in lieu of and substitution for this Warrant, a New Warrant,
          but only
          upon receipt of evidence reasonably satisfactory to the Company of such
          loss,
          theft or destruction and customary and reasonable indemnity (which shall
          not
          include a surety bond), if requested. Applicants for a New Warrant under
          such
          circumstances shall also comply with such other reasonable regulations
          and
          procedures and pay such other reasonable third-party costs as the Company
          may
          prescribe. If a New Warrant is requested as a result of a mutilation of
          this
          Warrant, then the Holder shall deliver such mutilated Warrant to the Company
          as
          a condition precedent to the Company’s obligation to issue the New Warrant.

        

        

        8.
           Reservation
          of Warrant Shares.
          The
          Company covenants that it will initially reserve and keep available out
          of the
          aggregate of its authorized but unissued and otherwise unreserved Common
          Stock,
          solely for the purpose of enabling it to issue Warrant Shares upon exercise
          of
          this Warrant as herein provided, [one hundred twenty percent (120%)] of
          the
          number of Warrant Shares which are initially issuable and deliverable upon
          the
          exercise of this entire Warrant, free from preemptive rights or any other
          contingent purchase rights of persons other than the Holder. The Company
          further
          covenants that it will at all times reserve and keep available out of the
          aggregate of its authorized but unissued and otherwise unreserved Common
          Stock,
          solely for the purpose of enabling it to issue Warrant Shares upon exercise
          of
          this Warrant as herein provided, the number of Warrant Shares which are
          then
          issuable and deliverable upon the exercise of this entire Warrant, free
          from
          preemptive rights or any other contingent purchase rights of persons other
          than
          the Holder (taking into account the adjustments and restrictions of Section
          9).
          The
          Company covenants that all Warrant Shares so issuable and deliverable shall,
          upon issuance and the payment of the applicable Exercise Price in accordance
          with the terms hereof, be duly and validly authorized, issued and fully
          paid and
          nonassessable. 

         

        9.
           Certain
          Adjustments.
          The
          Exercise Price and number of Warrant Shares issuable upon exercise of this
          Warrant are subject to adjustment from time to time as set forth in this
          Section
          9.
          

         

        
          
            
            

          

          
            -4-

            
              

            

          

          
            
            

          

        

        (a)  Stock
          Dividends and Splits.
          If the
          Company, at any time while this Warrant is outstanding, (i) pays a stock
          dividend on its Common Stock or otherwise makes a distribution on any class
          of
          capital stock that is payable in shares of Common Stock, (ii) subdivides
          its
          outstanding shares of Common Stock into a larger number of shares, or (iii)
          combines its outstanding shares of Common Stock into a smaller number of
          shares,
          then in each such case the Exercise Price shall be multiplied by a fraction
          of
          which the numerator shall be the number of shares of Common Stock outstanding
          immediately before such event and of which the denominator shall be the number
          of shares of Common Stock outstanding immediately after such event. Any
          adjustment made pursuant to clause (i) of this paragraph shall become effective
          immediately after the record date for the determination of stockholders
          entitled
          to receive such dividend or distribution, and any adjustment pursuant to
          clause
          (ii) or (iii) of this paragraph shall become effective immediately after
          the
          effective date of such subdivision or combination. 

         

        (b)
           Pro
          Rata Distributions.
          If the
          Company, at any time while this Warrant is outstanding, distributes to
          all
          holders of Common Stock (i) evidences of its indebtedness, (ii) any security
          (other than a distribution of Common Stock covered by the preceding paragraph),
          (iii) rights or warrants to subscribe for or purchase any security, or
          (iv) any
          other asset (in each case, “Distributed
          Property”),
          then,
          upon any exercise of this Warrant that occurs after the record date fixed
          for
          determination of stockholders entitled to receive such distribution, the
          Holder
          shall be entitled to receive, in addition to the Warrant Shares otherwise
          issuable upon such exercise (if applicable), the Distributed Property that
          such
          Holder would have been entitled to receive in respect of such number of
          Warrant
          Shares had the Holder been the record holder of such Warrant Shares immediately
          prior to such record date.

        

        (c) Fundamental
          Transactions.
          If, at
          any time while this Warrant is outstanding (i) the Company effects any
          merger or
          consolidation of the Company with or into another Person, in which the
          Company
          is not the survivor, (ii) the Company effects any sale of all or substantially
          all of its assets in one or a series of related transactions, (iii) any
          tender
          offer or exchange offer (whether by the Company or another Person) is completed
          pursuant to which holders of Common Stock are permitted to tender or exchange
          their shares for other securities, cash or property, or (iv) the Company
          effects
          any reclassification of the Common Stock or any compulsory share exchange
          pursuant to which the Common Stock is effectively converted into or exchanged
          for other securities, cash or property (each, a “Fundamental
          Transaction”),
          then
          the Holder shall have the right thereafter to receive, upon exercise of
          this
          Warrant, the same amount and kind of securities, cash or property as it
          would
          have been entitled to receive upon the occurrence of such Fundamental
          Transaction if it had been, immediately prior to such Fundamental Transaction,
          the holder of the number of Warrant Shares then issuable upon exercise
          in full
          of this Warrant (the “Alternate
          Consideration”).

         

        (d)
           Number
          of Warrant Shares.
          Simultaneously with any adjustment to the Exercise Price pursuant to paragraph
          (a) of this Section 9, the number of Warrant Shares that may be purchased
          upon
          exercise of this Warrant shall be increased or decreased proportionately,
          so
          that after such adjustment the aggregate Exercise Price payable hereunder
          for
          the adjusted number of Warrant Shares shall be the same as the aggregate
          Exercise Price in effect immediately prior to such adjustment. 

         

         (e)
           Calculations.
          All
          calculations under this Section
          9
          shall be
          made to the nearest cent or the nearest 1/100th
          of a
          share, as applicable. The number of shares of Common Stock outstanding
          at any
          given time shall not include shares owned or held by or for the account
          of the
          Company, and the disposition of any such shares shall be considered an
          issue or
          sale of Common Stock. 

        

        (f)
           Notice
          of Adjustments.
          Upon
          the occurrence of each adjustment pursuant to this Section
          9,
          the
          Company at its expense will, at the written request of the Holder, promptly
          compute such adjustment, in good faith, in accordance with the terms of
          this
          Warrant and prepare a certificate setting forth such adjustment, including
          a
          statement of the adjusted Exercise Price and adjusted number or type of
          Warrant
          Shares or other securities issuable upon exercise of this Warrant (as
          applicable), describing the transactions giving rise to such adjustments
          and
          showing in detail the facts upon which such adjustment is based. Upon written
          request, the Company will promptly deliver a copy of each such certificate
          to
          the Holder and to the Company’s Transfer Agent. 

         

        
          
            
            

          

          
            -5-

            
              

            

          

          
            
            

          

        

        (g)
           Notice
          of Corporate Events.
          If,
          while this Warrant is outstanding, the Company (i) declares a dividend
          or any
          other distribution of cash, securities or other property in respect of
          its
          Common Stock, including without limitation any granting of rights or warrants
          to
          subscribe for or purchase any capital stock of the Company or any Subsidiary,
          (ii) authorizes or approves, enters into any agreement contemplating, or
          solicits stockholder approval for any Fundamental Transaction or (iii)
          authorizes the voluntary dissolution, liquidation or winding up of the
          affairs
          of the Company, then, except if such notice and the contents thereof shall
          be
          deemed to constitute material non-public information, the Company shall
          deliver
          to the Holder a notice describing the material terms and conditions of
          such
          transaction at least ten (10) Trading Days prior to the applicable record
          or
          effective date on which a Person would need to hold Common Stock in order
          to
          participate in or vote with respect to such transaction, and the Company
          will
          take all reasonable steps to give the Holder the practical opportunity
          to
          exercise this Warrant prior to such time; provided,
          however,
          that
          the failure to deliver such notice or any defect therein shall not affect
          the
          validity of the corporate action required to be described in such notice.
          

         

        10.
           Payment
          of Exercise Price.
          The
          Holder may pay the Exercise Price in one of the following manners: 

         

        (a)
           Cash
          Exercise.
          The
          Holder may deliver immediately available funds; or 

         

        (b)
           Cashless
          Exercise.
          If an
          Exercise Notice is delivered at a time when a registration statement permitting
          the Holder to resell the Warrant Shares is required to be effective and
          is not
          then effective or the prospectus forming a part thereof is not then available
          to
          the Holder for the resale of the Warrant Shares, then the Holder may notify
          the
          Company in an Exercise Notice of its election to utilize cashless exercise,
          in
          which event the Company shall issue to the Holder the number of Warrant
          Shares
          determined as follows: 

         

        X
          = Y
          [(A-B)/A] 

         

        where:
          

         

        X
          = the
          number of Warrant Shares to be issued to the Holder. 

         

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

         

        A
          = the
          average of the closing prices of a share of Common Stock for the five Trading
          Days immediately prior to (but not including) the Exercise Date. 

         

        B
          = the
          Exercise Price. 

         

        For
          purposes of Rule 144 promulgated under the Securities Act, it is intended,
          understood and acknowledged that the Warrant Shares issued in a cashless
          exercise transaction shall be deemed to have been acquired by the Holder,
          and
          the holding period for the Warrant Shares shall be deemed to have commenced,
          on
          the date this Warrant was originally issued. 

         

        11.
           No
          Fractional Shares.
          No
          fractional Warrant Shares will be issued in connection with any exercise
          of this
          Warrant. In lieu of any fractional shares which would otherwise be issuable,
          the
          Company shall pay cash equal to the product of such fraction multiplied
          by the
          closing price of one Warrant Share as reported by the applicable Trading
          Market
          on the Exercise Date. 

         

        
          
            
            

          

          
            -6-

            
              

            

          

          
            
            

          

        

        12.
            Registration
          Rights and SEC Reporting Obligations of Company.
          

        

        (a)
          Piggy
          Back Registration Rights. If
          the
          Investor exercises any portion of the Warrant, and thereafter the Company
          proposes to file a registration statement under the Securities Act with
          respect
          to an offering for its own account of any class of its equity securities
          (other
          than a registration statement on Form S-8 (or any

        successor
          form) or any other registration statement relating solely to employee benefit
          plans or filed in connection with an exchange offer, then the Company shall
          in
          each case give written notice of such proposed filing to the Holder as
          soon as
          practicable (but no later than 20 business days) before the anticipated
          filing
          date, and such notice shall offer each Holder the opportunity to register
          such
          number of shares of Warrant Shares as such Holder may request. Each Holder
          desiring to have Warrant Shares included in such registration statement
          shall so
          advise the Company in writing within 10 business days after the date on
          which
          the Company’s notice is so given, setting forth the number of shares of Warrant
          Shares for which registration is requested. If the Company's offering is
          to be
          an underwritten offering, the Company shall use its reasonable best efforts
          to
          cause the managing underwriter or underwriters to permit the Holders of
          the
          Warrant Shares requested to be included in the registration for such offering
          to
          include such Warrant Shares in such offering on the same terms and conditions
          as
          any similar securities of the Company included therein. 

        

        

        (b)
          SEC
          Reporting Obligation.
          The
          Company agrees to make publicly available adequate public information necessary
          for the Holder to transfer the Warrant Shares pursuant to Rule 144 promulgated
          under the Securities Act (“Rule
          144”)
          by
          providing the following: 

        

        
          	 	
                  (i)

                	
                  For
                    so long at the Company is subject to the reporting requirements
                    of Section
                    13 or 15(d) of the Securities Exchange Act of 1934, as amended,
                    (the
                    “Exchange
                    Act”),
                    the Company shall timely file (inclusive of any extensions) all
                    required
                    reports under Section 13 or 15(d) of the Exchange Act, as applicable,
                    (other than Form 8-K reports). 

                

        

        
          	 	
                  (ii)

                	
                  If
                    the Company is not subject to the reporting requirements of Section
                    13 or

          and
          their respective successors and assigns. Subject to the preceding sentence,

        (b)
           All

          of this Warrant shall be governed by and construed and enforced in accordance
          with the internal laws of the State of New York, without regard to the

          proceedings concerning the interpretations, enforcement and defense of
          this
          Warrant and the transactions herein contemplated (“Proceedings”)
          (whether brought against a party hereto or its respective Affiliates, employees
          or agents) shall be commenced exclusively in the New York Courts. Each
          party
          hereto hereby irrevocably submits to the exclusive jurisdiction of the
          New York
          Courts for the adjudication of any dispute hereunder or in connection herewith
          or with any transaction contemplated hereby or discussed herein, and hereby

          such Proceeding has been commenced in an improper or inconvenient forum.
          Each
          party hereto hereby irrevocably waives personal service of process and
          consents
          to process being served in any such Proceeding by mailing a copy thereof

          any way
          any right to serve process in any manner permitted by law. Each party hereto
          hereby irrevocably waives, to the fullest extent permitted by applicable
          law,
          any and all right to trial by jury in any legal proceeding arising out
          of or
          relating to this Warrant or the transactions contemplated hereby. If either
          party shall commence a Proceeding to enforce any provisions of this Warrant,
          then the prevailing party in such Proceeding shall be reimbursed by the
          other
          party for its attorney’s fees and other costs and expenses incurred in
          connection with the investigation, preparation and prosecution of such
          Proceeding.

          Warrant and shall not be deemed to limit or affect any of the provisions
          hereof.

         

        (d)
           In
          case
          any one or more of the provisions of this Warrant shall be invalid or
          unenforceable in any respect, the validity and enforceability of the remaining
          terms and provisions of this Warrant shall not in any way be affected or
          impaired thereby and the parties will attempt in good faith to agree upon
          a
          valid and enforceable provision which shall be a commercially reasonable
          substitute therefor, and upon so agreeing, shall incorporate such substitute
          provision in this Warrant. 

         

        (e)
           Other
          than as otherwise set forth herein, prior to exercise of this Warrant,
          the
          Holder hereof shall not, by reason of by being a Holder, be entitled to

          rights of a stockholder with respect to the Warrant Shares
