        of effecting any of the foregoing;

      5. Rights

        Upon

        of
        Default described in Sections 4(c)
        or
4(d))
        and at
        any time thereafter during the continuance of such Event of Default, Investor
        may, with the consent of the Agent, by written notice to the Company, declare
        all outstanding Obligations payable by the Company hereunder to be immediately
        due and payable without presentment, demand, protest or any other notice
        of any
        kind, all of which are hereby expressly waived. Upon the occurrence or existence
        of any Event of Default described in Sections 4(c)
        and
4(d), immediately
        and without notice, all outstanding Obligations payable by the Company hereunder
        shall automatically become immediately due and payable, without presentment,
        demand, protest or any other notice of any kind, all of which are hereby
        expressly waived. In addition to the foregoing remedies, upon the occurrence
        or
        existence of any Event of Default and subject to the consent of the Agent,
        Investor may exercise any other right power or remedy granted to it by the
        Transaction Documents or otherwise permitted to it by law, either by suit
        in
        equity or by action at law, or both.

       

      
        
           

        

        
          -4-

          
            

          

        

        
           

        

      

       

      6. Conversion.

      


      (a) Optional
        Conversion.
        At the
        Maturity Date, each Investor shall have the option to convert the entire
        principal amount of this Note then outstanding into Common Stock. The number
        of
        shares of Common Stock that this Note may be converted into shall be determined
        by dividing the principal amount then outstanding by the Conversion Price
        at the
        time of conversion. If the Investor elects to convert this Note at maturity,
        it
        shall provide the Company with written notice of its election at least one
        (1)
        day prior to the Maturity Date. Upon conversion, the Investor shall deliver
        to
        the Company the original of this Note (or a notice to the effect that the
        original Note has been lost, stolen or destroyed and an agreement reasonably
        acceptable to the Company whereby the holder agrees to indemnify the Company
        from any loss incurred by it in connection with this Note). However, upon
        such
        conversion of this Note, this Note shall be deemed converted and of no further
        force and effect, whether or not the Note is delivered for cancellation as
        set
        forth in the preceding sentence. If there shall occur a Change of Control,
        the
        Company shall give written notice to the Investor at least five (5) days
        prior
        to any closing thereof and the Investor’s election to convert this Note shall be
        conditional upon the consummation thereof.

      


      (b) Mechanics
        of Optional Conversion.
        As soon
        as practicable following surrender by the Investor of the original of its
        Note,
        the Company shall issue and deliver to Investor a certificate or certificates
        for the shares of Common Stock into which the Note has been converted (bearing
        such legends as may be required or advisable in the opinion of counsel to
        the
        Company). Such conversion shall be deemed to have been made immediately prior
        to
        the close of business on the Maturity Date, and the Investor shall be treated
        for all purposes as the record holder or holders of such Common Stock on
        such
        date.

      


      (c) Fractional
        Shares; Interest; Effect of Conversion. No
        fractional shares shall be issued upon conversion of this Note. In lieu of
        the
        Company issuing any fractional shares to Investor upon the conversion of
        this
        Note, the Company shall pay to Investor an amount equal to the product obtained
        by multiplying the Conversion Price by the fraction of a share not issued
        pursuant to the previous sentence. Upon conversion of this Note in full and
        the
        payment of any amounts specified in this Section 6(c),
        the
        Company shall be forever released from all its obligations and liabilities
        under
        this Note.

      


      7. Successors
        and Assigns.
        Subject
        to the restrictions on transfer described in Sections 9
        and
10
        below,
        the rights and obligations of the Company and Investor shall be binding upon
        and
        benefit the successors, assigns, heirs, administrators and transferees of
        the
        parties.

      


      8. Waiver
        and Amendment.
        Any
        provision of this Note may be amended, waived or modified upon the written
        consent of the Company and the holders of a Requisite Percentage.

       

      
        
           

        

        
          -5-

          
            

          

        

        
           

        

      

       

      9. Transfer
        of this Note or Securities Issuable on Conversion
        Hereof.
        With
        respect to any offer, sale or other disposition of this Note or securities
        into
        which such Note may be converted, Investor will give written notice to the
        Company prior thereto, describing briefly the manner thereof, together with
        (unless waived by the Company) a written opinion of Investor’s counsel, or other
        evidence if reasonably satisfactory to the Company, to the effect that such
        offer, sale or other distribution may be effected without registration or
        qualification (under any federal or state law then in effect). Upon receiving
        such written notice and reasonably satisfactory opinion, if so requested,
        or
        other evidence, the Company, as promptly as practicable, shall notify Investor
        that Investor may sell or otherwise dispose of this Note or such securities,
        all
        in accordance with the terms of the notice delivered to the Company. If a
        determination has been made pursuant to this Section 9
        that the
        opinion of counsel for Investor, or other evidence, is not reasonably
        satisfactory to the Company, the Company shall so notify Investor promptly
        after
        such determination has been made. Each Note thus transferred and each
        certificate representing the securities thus transferred shall bear a legend
        as
        to the applicable restrictions on transferability in order to ensure compliance
        with the Securities Act, unless in the opinion of counsel for the Company
        such
        legend is not required in order to ensure compliance with the Securities
        Act.
        The Company may issue stop transfer instructions to its transfer agent in
        connection with such restrictions. Subject to the foregoing, transfers of
        this
        Note shall be registered upon registration books maintained for such purpose
        by
        or on behalf of the Company. Prior to presentation of this Note for registration
        of transfer, the Company shall treat the registered holder hereof as the

        Passu Notes.
        Investor
        acknowledges and agrees that the payment of all or any portion of the
        outstanding principal amount of this Note and all interest hereon shall be
        pari
        passu in
        right
        of payment and in all other respects to the other Notes issued pursuant to
        the
        Note Purchase Agreement or pursuant to the terms of such Notes. In the event
        Investor receives payments in excess of its pro rata share of the Company’s

        all such excess payments for the benefit of the holders of the other Notes

      13. Usury.
        In the
        event any interest is paid on this Note which is deemed to be in excess of
        the
        then legal maximum rate, then that portion of the interest payment representing
        an amount in excess of the then legal maximum rate shall be deemed a payment
        of
        principal and applied against the principal of this Note.

      


      14. Waivers.
        The
        Company hereby waives notice of default, presentment or demand for payment,
        protest or notice of nonpayment or dishonor and all other notices or demands
        relative to this instrument.

      


      15. Remedies
        Cumulative.
        The
        remedies of Investor as provided herein and in the Note Purchase Agreement
        and
        in any other documents governing or securing repayment hereof shall be
        cumulative and concurrent and may be pursued singly, successively, or together,
        at the sole discretion of Investor to the extent provided herein and in the
        Note
        Purchase Agreement and may be exercised as often as occasion therefore shall
        arise. No act or omission of the Investor, including specifically, but without
        limitation, any failure to exercise any right, remedy or recourse, shall
        be
        effective as a waiver of any right of the Investor hereunder, unless set
        forth
        in a written document executed by the Investor, and then only to the extent
        specifically recited therein. A waiver or release with reference to one event
        shall not be construed as continuing, as a bar to, or as a waiver or release
        of
        any subsequent right, remedy or recourse as to any subsequent event. All
        notices, waivers, releases and/or consents by an Investor shall be directed
        to
        the Company only through the Agent.

      


      16. No
        Rights of a Stockholder.
        Nothing
        contained in this Note shall be construed as conferring upon the Investor
        or any
        other Person the right to vote or consent or to receive notice as an stockholder
        in respect of meetings of stockholders for the election of directors of the
        Company or any other matters or any rights whatsoever as a stockholder of
        the
        Company prior to the time that this Note is converted pursuant to Section
        6.

      


      17. Governing
        Law.
        This
        Note and all actions arising out of or in connection with this Note shall
        be
        governed by and construed in accordance with the laws of the State of Delaware,
        without regard to the conflicts of law provisions of the State of Delaware,
        or
        of any other state.
