    ARTICLE II
CONVERSION
      RIGHTS
    The
      Holder shall have the right to convert the principal due under this Note into
      Shares of the Borrower's Common Stock, no par value per share (“Common Stock”)
      as set forth below.
    2.1. Conversion
      into the Borrower's Common Stock.
    (a) The
      Holder shall have the right from and after the date of the issuance of this
      Note
      and then at any time until this Note is fully paid, to convert any outstanding
      and unpaid principal portion of this Note, and accrued interest, at the election
      of the Holder (the date of giving of such notice of conversion being a
      "Conversion Date") into fully paid and nonassessable shares of Common Stock
      as
      such stock exists on the date of issuance of this Note, or any shares of capital
      stock of Borrower into which such Common Stock shall hereafter be changed or
      reclassified, at the conversion price as defined in Section 2.1(b) hereof (the
      "Conversion Price"), determined as provided herein. Upon delivery to the
      Borrower of a completed Notice of Conversion, a form of which is annexed hereto,
      Borrower shall issue and deliver to the Holder within four (4) business days
      from the Conversion Date (such third day being the “Delivery Date”) that number
      of shares of Common Stock for the portion of the Note converted in accordance
      with the foregoing. At the election of the Holder, the Borrower will deliver
      accrued but unpaid interest on the Note in the manner provided in Section 1.3
      through the Conversion Date directly to the Holder on or before the Delivery
      Date (as defined in the Subscription Agreement). The number of shares of Common
      Stock to be issued upon each conversion of this Note shall be determined by
      dividing that portion of the principal of the Note and interest to be converted,
      by the Conversion Price.
    (b)  Subject
      to adjustment as provided in Section 2.1(c) hereof, the Conversion Price per
      share shall be the lesser of: (i) seventy percent (70%) of the average of the
      five lowest closing bid prices for the Common Stock as reported by Bloomberg
      L.P. for the Principal Market for the ten trading days preceding a Conversion
      Date, or (ii) $0.55.
    (c) 
      The
      Conversion Price and number and kind of shares or other securities to be issued
      upon conversion determined pursuant to Section 2.1(a), shall be subject to
      adjustment from time to time upon the happening of certain events while this
      conversion right remains outstanding, as follows:
    A. Merger,
      Sale of Assets, etc. If the Borrower at any time shall consolidate with or
      merge
      into or sell or convey all or substantially all its assets to any other
      corporation, this Note, as to the unpaid principal portion thereof and accrued
      interest thereon, shall thereafter be deemed to evidence the right to purchase
      such number and kind of shares or other securities and property as would have
      been issuable or distributable on account of such consolidation, merger, sale
      or
      conveyance, upon or with respect to the securities subject to the conversion
      or
      purchase right immediately prior to such consolidation, merger, sale or
      conveyance. The foregoing provision shall similarly apply to successive
      transactions of a similar nature by any such successor or purchaser. Without
      limiting the generality of the foregoing, the anti-dilution provisions of this
      Section shall apply to such securities of such successor or purchaser after
      any
      such consolidation, merger, sale or conveyance.
    B. Reclassification,
      etc. If the Borrower at any time shall, by reclassification or otherwise, change
      the Common Stock into the same or a different number of securities of any class
      or classes that may be issued or outstanding, this Note, as to the unpaid
      principal portion thereof and accrued interest thereon, shall thereafter be
      deemed to evidence the right to purchase an adjusted number of such securities
      and kind of securities as would have been issuable as the result of such change
      with respect to the Common Stock immediately prior to such reclassification
      or
      other change.
    C. Stock
      Splits, Combinations and Dividends. If the shares of Common Stock are subdivided
      or combined into a greater or smaller number of shares of Common Stock, or
      if a
      dividend is paid on the Common Stock in shares of Common Stock, the Conversion
      Price shall be proportionately reduced in case of subdivision of shares or
      stock
      dividend or proportionately increased in the case of combination of shares,
      in
      each such case by the ratio which the total number of shares of Common Stock
      outstanding immediately after such event bears to the total number of shares
      of
      Common Stock outstanding immediately prior to such event..
    D. Share
      Issuance. So long as this Note is outstanding, if the Borrower shall issue
      or
      agree to issue any shares of Common Stock except for the Excepted Issuances
      (as
      defined in the Subscription Agreement) for a consideration less than the
      Conversion Price in effect at the time of such issue, then, and thereafter
      successively upon each such issue, the Conversion Price shall be reduced to
      such
      other lower issue price. For purposes of this adjustment, the issuance of any
      security carrying the right to convert such security into shares of Common
      Stock
      or of any warrant, right or option to purchase Common Stock shall result in
      an
      adjustment to the Conversion Price upon the issuance of the above-described
      security and again upon the issuance of shares of Common Stock upon exercise
      of
      such conversion or purchase rights if such issuance is at a price lower than
      the
      then applicable Maximum Base Price. The reduction of the Conversion Price
      described in this paragraph is in addition to other rights of the Holder
      described in this Note and the Subscription Agreement.
    (d) Whenever
      the Conversion Price is adjusted pursuant to Section 2.1(c) above, the Borrower
      shall promptly mail to the Holder a notice setting forth the Conversion Price
      after such adjustment and setting forth a statement of the facts requiring
      such
      adjustment.
    (e) During
      the period the conversion right exists, Borrower will reserve from its
      authorized and unissued Common Stock not less than 200% of the number of shares
      of Common Stock issuable upon the full conversion of this Note. Borrower
      represents that upon issuance, such shares will be duly and validly issued,
      fully paid and non-assessable. Borrower agrees that its issuance of this Note
      shall constitute full authority to its officers, agents, and transfer agents
      who
      are charged with the duty of executing and issuing stock certificates to execute
      and issue the necessary certificates for shares of Common Stock upon the
      conversion of this Note.
    2.2 Method
      of Conversion.
      This
      Note may be converted by the Holder in whole or in part as described in Section
      2.1(a) hereof and the Subscription Agreement. Upon partial conversion of this
      Note, a new Note containing the same date and provisions of this Note shall,
      at
      the request of the Holder, be issued by the Borrower to the Holder for the
      principal balance of this Note and interest which shall not have been converted
      or paid.
    2.3 Maximum
      Conversion.
      The
      Holder shall not be entitled to convert on a Conversion Date that amount of
      the
      Note in connection with that number of shares of Common Stock which would be
      in
      excess of the sum of (i) the number of shares of Common Stock beneficially
      owned
      by the Holder and its affiliates on a Conversion Date, (ii) any Common Stock
      issuable in connection with the unconverted portion of the Note, and (iii)
      the
      number of shares of Common Stock issuable upon the conversion of the Note with
      respect to which the determination of this provision is being made on a
      Conversion Date, which would result in beneficial ownership by the Holder and
      its affiliates of more than 4.99% of the outstanding shares of Common Stock
      of
      the Borrower on such Conversion Date. For the purposes of the provision to
      the
      immediately preceding sentence, beneficial ownership shall be determined in
      accordance with Section 13(d) of the Securities Exchange Act of 1934, as
      amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder
      shall not be limited to aggregate conversions of only 4.99% and aggregate
      conversion by the Holder may exceed 4.99%. The Holder shall have the authority
      and obligation to determine whether the restriction contained in this Section
      2.3 will limit any conversion hereunder and to the extent that the Holder
      determines that the limitation contained in this Section applies, the
      determination of which portion of the Notes are convertible shall be the
      responsibility and obligation of the Holder. The Holder may waive the conversion
      limitation described in this Section 2.3, in whole or in part, upon and
      effective after 61 days prior written notice to the Borrower. The Holder may
      allocate which of the equity of the Borrower deemed beneficially owned by the
      Holder shall be included in the 4.99% amount described above and which shall
      be
      allocated to the excess above 4.99%.
    2.4. Optional
      Redemption of Principal Amount.
      Provided an Event of Default has not occurred, whether or not such Event of
      Default has been cured and further provided that the Common Stock has had a
      closing price of more than $1.50 as reported by Bloomberg L.P. for the Principal
      Market for twenty consecutive trading days, the Borrower will have the option
      of
      prepaying the outstanding Principal Amount ("Optional Redemption"), in whole
      or
      in part, by paying to the Holder a sum of money equal to one hundred and thirty
      percent (130%) of the Principal Amount to be redeemed, together with accrued
      but
      unpaid interest thereon and any and all other sums due, accrued or payable
      to
      the Holder arising under this Note or any Transaction Document through the
      Redemption Payment Date as defined below (the "Redemption Amount"). Borrower’s
      election to exercise its right to prepay must be by notice in writing (“Notice
      of Redemption”). The Notice of Redemption shall specify the date for such
      Optional Redemption (the "Redemption Payment Date"), which date shall be ten
      (10) business days after the date of the Notice of Redemption (the "Redemption
      Period"). A Notice of Redemption shall not be effective with respect to any
      portion of the Principal Amount for which the Holder has a pending election
      to
      convert pursuant to Section 2.1, or for conversions initiated or made by the
      Holder pursuant to Section 2.1 during the Redemption Period. On the Redemption
      Payment Date, the Redemption Amount, less any portion of the Redemption Amount
      against which the Holder has exercised its rights pursuant to Section 2.1,
      shall
      be paid in good funds to the Holder. In the event the Borrower fails to pay
      the
      Redemption Amount on the Redemption Payment Date as set forth herein, then
      (i)
      such Notice of Redemption will be null and void, (ii) Borrower will have no
      right to deliver another Notice of Redemption, and (iii) Borrower’s failure may
      be deemed by Holder to be a non-curable Event of Default.
