    New

      New York

     

    November
      14, 2007                                                                                             $21,200

     

    FOR
      VALUE RECEIVED, AVITAR INC., a Delaware corporation
      (hereinafter called the “Borrower”), hereby promises to pay to
      the order of AJW PARTNERS, LLC or registered assigns (the
“Holder”) the sum of $21,200, on November 14, 2010 (the
“Maturity Date”), and to pay interest on the unpaid principal
      balance hereof at the rate of eight percent (8%) (the “Interest
      Rate”) per annum from November 14, 2007 (the “Issue
      Date”) until the same becomes due and payable, whether at maturity or
      upon acceleration or by prepayment or otherwise.  Any amount of
      principal or interest on this Note which is not paid when due shall bear
      interest at the rate of fifteen percent (15%) per annum from the due date
      thereof until the same is paid (“Default
      Interest”).  Interest shall commence accruing on the Issue
      Date, shall be computed on the basis of a 365-day year and the actual number
      of
      days elapsed and shall be payable quarterly provided that no interest shall
      be
      due and payable for any month in which the Trading Price (as such term is
      defined below) is greater than $.20 for each Trading Day (as such term is
      defined below) of the month. All payments due hereunder (to the extent not
      converted into common stock, $.01 par value per share (the “Common
      Stock”) in accordance with the terms hereof) shall be made in lawful
      money of the United States of America.  All payments shall be made at
      such address as the Holder shall hereafter give to the Borrower by written
      notice made in accordance with the provisions of this Note.  Whenever
      any amount expressed to be due by the terms of this Note is due on any day
      which
      is not a business day, the same shall instead be due on the next succeeding
      day
      which is a business day and, in the case of any interest payment date which
      is
      not the date on which this Note is paid in full, the extension of the due date
      thereof shall not be taken into account for purposes of determining the amount
      of interest due on such date.  As used in this Note, the term
“business day” shall mean any day other than a Saturday, Sunday or a day on
      which commercial banks in the city of New York, New York are authorized or
      required by law or executive order to remain closed.  Each capitalized
      term used herein, and not otherwise defined, shall have the meaning ascribed
      thereto in that certain Securities Purchase Agreement, dated November 14, 2007,
      pursuant to which this Note was originally issued (the “Purchase
      Agreement”).

     

    This
      Note
      is free from all taxes, liens, claims and encumbrances with respect to the
      issue
      thereof and shall not be subject to preemptive rights or other similar rights
      of
      shareholders of the Borrower and will not impose personal liability upon the
      holder thereof.  The obligations of the Borrower under this Note shall
      be secured by that certain Security Agreement and Intellectual Property Security
      Agreement, each dated November 14, 2007 by and between the Borrower and the
      Holder.

     

    The
      following terms shall apply to this Note:

     

     

    ARTICLE
      I.     CONVERSION RIGHTS

     

    1.1  Conversion
      Right.  The Holder shall have the right
      from time to time, and at any time on or prior to the earlier of (i) the
      Maturity Date and (ii) the date of payment of the Default Amount (as defined
      in
      Article III) pursuant to Section 1.6(a) or Article III, the Optional Prepayment
      Amount (as defined in Section 5.1 or any payments pursuant to Section 1.7,
      each
      in respect of the remaining outstanding principal amount of this Note to convert
      all or any part of the outstanding and unpaid principal amount of this Note
      into
      fully paid and non-assessable shares of Common Stock, as such Common Stock
      exists on the Issue Date, or any shares of capital stock or other securities
      of
      the Borrower into which such Common Stock shall hereafter be changed or
      reclassified at the conversion price  (the “Conversion
      Price”) determined as provided herein (a
“Conversion”); provided, however, that in no
      event shall the Holder be entitled to convert any portion of this Note in excess
      of that portion of this Note upon conversion of which the sum of (1) the number
      of shares of Common Stock beneficially owned by the Holder and its affiliates
      (other than shares of Common Stock which may be deemed beneficially owned
      through the ownership of the unconverted portion of the Notes or the unexercised
      or unconverted portion of any other security of the Borrower (including, without
      limitation, the warrants issued by the Borrower pursuant to the Purchase
      Agreement) subject to a limitation on conversion or exercise analogous to the
      limitations contained herein) and (2) the number of shares of Common Stock
      issuable upon the conversion of the portion of this Note with respect to which
      the determination of this proviso is being made, would result in beneficial
      ownership by the Holder and its affiliates of more than 4.99% of the outstanding
      shares of Common Stock and providedfurther that the Holder shall
      not be entitled to convert any portion of this Note during any month immediately
      succeeding a Determination Date on which the Borrower exercises its prepayment
      option pursuant to Section 5.2 of this Note.  For purposes of the
      proviso 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 Regulations 13D-G thereunder, except as otherwise provided
      in clause (1) of such proviso.  The number of shares of Common Stock
      to be issued upon each conversion of this Note shall be determined by dividing
      the Conversion Amount (as defined below) by the applicable Conversion Price
      then
      in effect on the date specified in the notice of conversion, in the form
      attached hereto as Exhibit A (the “Notice of Conversion”),
      delivered to the Borrower by the Holder in accordance with Section 1.4 below;
      provided that the Notice of Conversion is submitted by facsimile (or by other
      means resulting in, or reasonably expected to result in, notice) to the Borrower
      before 6:00 p.m., New York, New York time on such conversion date (the
“Conversion Date”).  The term “Conversion
      Amount” means, with respect to any conversion of this Note, the sum of
      (1) the principal amount of this Note to be converted in such conversion
plus (2) accrued and unpaid interest, if any, on such principal amount
      at
      the interest rates provided in this Note to the Conversion Date, provided,
      however, that the Company shall have the right to pay any or all interest in
      cash plus (3) Default Interest, if any, on the amounts referred to in the
      immediately preceding clauses (1) and/or (2) plus (4) at the Holder’s
      option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g)
      hereof or pursuant to Section 2(c) of that certain Registration Rights
      Agreement, dated as of November 14, 2007, executed in connection with the
      initial issuance of this Note and the other Notes issued on the Issue Date
      (the
“Registration Rights Agreement”).  The term
“Determination Date” means the last business day of each month
      after the Issue Date.

     

    1.2  Conversion
      Price.

     

    (a)  Calculation
      of Conversion Price.  The Conversion
      Price shall be the Variable Conversion Price (as defined herein) (subject,
      in
      each case, to equitable adjustments for stock splits, stock dividends or rights
      offerings by the Borrower relating to the Borrower’s securities or the
      securities of any subsidiary of the Borrower, combinations, recapitalization,
      reclassifications, extraordinary distributions and similar
      events).  The “Variable Conversion Price” shall mean
      the Applicable Percentage (as defined herein) multiplied by the Market Price
      (as
      defined herein).  “Market Price” means the average of
      the lowest three (3) Trading Prices (as defined below) for the Common Stock
      during the twenty (20) Trading Day period ending one Trading Day prior to the
      date the Conversion Notice is sent by the Holder to the Borrower via facsimile
      (the “Conversion Date”).  “Trading
      Price” means, for any security as of any date, the intraday trading
      price on the Over-the-Counter Bulletin Board (the “OTCBB”) as
      reported by a reliable reporting service (“Reporting Service”)
      mutually acceptable to Borrower and Holder and hereafter designated by Holders
      of a majority in interest of the Notes and the Borrower or, if the OTCBB is
      not
      the principal trading market for such security, the intraday trading price
      of
      such security on the principal securities exchange or trading market where
      such
      security is listed or traded or, if no intraday trading price of such security
      is available in any of the foregoing manners, the average of the intraday
      trading prices of any market makers for such security that are listed in the
      “pink sheets” by the National Quotation Bureau, Inc.  If the Trading
      Price cannot be calculated for such security on such date in the manner provided
      above, the Trading Price shall be the fair market value as mutually determined
      by the Borrower and the holders of a majority in interest of the Notes being
      converted for which the calculation of the Trading Price is required in order
      to
      determine the Conversion Price of such Notes.  “Trading
      Day” shall mean any day on which the Common Stock is traded for any
      period on the OTCBB, or on the principal securities exchange or other securities
      market on which the Common Stock is then being
      traded.  “Applicable Percentage” shall mean
      40.0%.

     

    (b)  Conversion
      Price During Major
      Announcements.  Notwithstanding anything
      contained in Section 1.2(a) to the contrary, in the event the Borrower (i)
      makes
      a public announcement that it intends to consolidate or merge with any other
      corporation (other than a merger in which the Borrower is the surviving or
      continuing corporation and its capital stock is unchanged) or sell or transfer
      all or substantially all of the assets of the Borrower or (ii) any person,
      group
      or entity (including the Borrower) publicly announces a tender offer to purchase
      50% or more of the Borrower’s Common Stock (or any other takeover scheme) (the
      date of the announcement referred to in clause (i) or (ii) is hereinafter
      referred to as the  “Announcement Date”), then the
      Conversion Price shall, effective upon the Announcement Date and continuing
      through the Adjusted Conversion Price Termination Date (as defined below),
      be
      equal to the lower of (x) the Conversion Price which would have been applicable
      for a Conversion occurring on the Announcement Date and (y) the Conversion
      Price
      that would otherwise be in effect. From and after the Adjusted Conversion Price
      Termination Date, the Conversion Price shall be determined as set forth in
      this
      Section 1.2(a).  For purposes hereof,  “Adjusted
      Conversion Price Termination Date” shall mean, with respect to any
      proposed transaction or tender offer (or takeover scheme) for which a public
      announcement as contemplated by this Section 1.2(b) has been made, the date
      upon
      which the Borrower (in the case of clause (i) above) or the person, group or
      entity (in the case of clause (ii) above) consummates or publicly announces
      the
      termination or abandonment of the proposed transaction or tender offer (or
      takeover scheme) which caused this Section 1.2(b) to become
      operative.

     

    1.3  Authorized
      Shares.  Subject to Stockholder Approval
      (as such term is defined in Section 4(n) of the Securities Purchase Agreement),
      the Borrower covenants that during the period the conversion right exists,
      the
      Borrower will reserve from its authorized and unissued Common Stock a sufficient
      number of shares, free from preemptive rights, to provide for the issuance
      of
      Common Stock upon the full conversion of this Note and the other Notes issued
      pursuant to the Purchase Agreement.  The Borrower is required at all
      times to have authorized and reserved two times the number of shares that is
      actually issuable upon full conversion of the Notes (based on the Conversion
      Price of the Notes or the Exercise Price of the Warrants in effect from time
      to
      time) (the “Reserved Amount”).  The Reserved Amount
      shall be increased from time to time in accordance with the Borrower’s
      obligations pursuant to Section 4(h) of the Purchase Agreement.  The
      Borrower represents that upon issuance, such shares will be duly and validly
      issued, fully paid and non-assessable.  In addition, if the Borrower
      shall issue any securities or make any change to its capital structure which
      would change the number of shares of Common Stock into which the Notes shall
      be
      convertible at the then current Conversion Price, the Borrower shall at the
      same
      time make proper provision so that thereafter there shall be a sufficient number
      of shares of Common Stock authorized and reserved, free from preemptive rights,
      for conversion of the outstanding Notes.  The Borrower (i)
      acknowledges that it has irrevocably instructed its transfer agent to issue
      certificates for the Common Stock issuable upon conversion of this Note, and
      (ii) agrees that its issuance of this Note shall constitute full authority
      to its officers and agents who are charged with the duty of executing stock
      certificates to execute and issue the necessary certificates for shares of
      Common Stock in accordance with the terms and conditions of this
      Note.

     

    If,
      at
      any time a Holder of this Note submits a Notice of Conversion, and the Borrower
      does not have sufficient authorized but unissued shares of Common Stock
      available to effect such conversion in accordance with the provisions of this
      Article I (a “Conversion Default”), subject to Section 4.8, the
      Borrower shall issue to the Holder all of the shares of Common Stock which
      are
      then available to effect such conversion.  The portion of this Note
      which the Holder included in its Conversion Notice and which exceeds the amount
      which is then convertible into available shares of Common Stock (the
“Excess Amount”) shall, notwithstanding anything to the
      contrary contained herein, not be convertible into Common Stock in accordance
      with the terms hereof until (and at the Holder’s option at any time after) the
      date additional shares of Common Stock are authorized by the Borrower to permit
      such conversion, at which time the Conversion Price in respect thereof shall
      be
      the lesser of (i) the Conversion Price on the Conversion Default Date (as
      defined below) and (ii) the Conversion Price on the Conversion Date thereafter
      elected by the Holder in respect thereof.  In addition, the Borrower
      shall pay to the Holder payments (“Conversion Default
      Payments”) for a Conversion Default in the amount of (x) the sum
      of (1) the then outstanding principal amount of this Note plus (2)
      accrued and unpaid interest on the unpaid principal amount of this Note through
      the Authorization Date (as defined below) plus (3) Default Interest, if
      any, on the amounts referred to in clauses (1) and/or (2), multiplied by
      (y) .24, multiplied by (z) (N/365), where N = the number of days from the
      day the holder submits a Notice of Conversion giving rise to a Conversion
      Default (the “Conversion Default Date”) to the date (the
“Authorization Date”) that the Borrower authorizes a sufficient
      number of shares of Common Stock to effect conversion of the full outstanding
      principal balance of this Note.  The Borrower shall use its best
      efforts to authorize a sufficient number of shares of Common Stock as soon
      as
      practicable following the earlier of (i) such time that the Holder notifies
      the
      Borrower or that the Borrower otherwise becomes aware that there are or likely
      will be insufficient authorized and unissued shares to allow full conversion
      thereof and (ii) a Conversion Default.  The Borrower shall send notice
      to the Holder of the authorization of additional shares of Common Stock, the
      Authorization Date and the amount of Holder’s accrued Conversion Default
      Payments.  The accrued Conversion Default Payments for each calendar
      month shall be paid in cash or shall be convertible into Common Stock (at such
      time as there are sufficient authorized shares of Common Stock) at the
      applicable Conversion Price, at the Borrower’s option, as follows:

     

    (a)  In
      the
      event Holder elects to take such payment in cash, cash payment shall be made
      to
      Holder by the fifth (5th) day of
      the month
      following the month in which it has accrued; and

     

    (b)  In
      the
      event Holder elects to take such payment in Common Stock, the Holder may convert
      such payment amount into Common Stock at the Conversion Price (as in effect
      at
      the time of conversion) at any time after the fifth day of the month following
      the month in which it has accrued in accordance with the terms of this Article
      I
      (so long as there is then a sufficient number of authorized shares of Common
      Stock).

     

    The
      Holder’s election shall be made in writing to the Borrower at any time prior to
      6:00 p.m., New York, New York time, on the third day of the month following
      the
      month in which Conversion Default payments have accrued.  If no
      election is made, the Holder shall be deemed to have elected to receive
      cash.  Nothing herein shall limit the Holder’s right to pursue actual
      damages (to the extent in excess of the Conversion Default Payments) for the
      Borrower’s failure to maintain a sufficient number of authorized shares of
      Common Stock, and each holder shall have the right to pursue all remedies
      available at law or in equity (including degree of specific performance and/or
      injunctive relief).

     

    1.4  Method
      of Conversion.

     

    (a)  Mechanics
      of Conversion.  Subject to Section 1.1,
      this Note may be converted by the Holder in whole or in part at any time from
      time to time after the Issue Date, by (A) submitting to the Borrower a
      Notice of Conversion (by facsimile or other reasonable means of communication
      dispatched on the Conversion Date prior to 6:00 p.m., New York, New York time)
      and (B) subject to Section 1.4(b), surrendering this Note at the principal
      office of the Borrower.

     

    (b)  Surrender
      of Note Upon
      Conversion.  Notwithstanding anything to
      the contrary set forth herein, upon conversion of this Note in accordance with
      the terms hereof, the Holder shall not be required to physically surrender
      this
      Note to the Borrower unless the entire unpaid principal amount of this Note
      is
      so converted.  The Holder and the Borrower shall maintain records
      showing the principal amount so converted and the dates of such conversions
      or
      shall use such other method, reasonably satisfactory to the Holder and the
      Borrower, so as not to require physical surrender of this Note upon each such
      conversion.  In the event of any dispute or discrepancy, such records
      of the Borrower shall be controlling and determinative in the absence of
      manifest error.  Notwithstanding the foregoing, if any portion of this
      Note is converted as aforesaid, the Holder may not transfer this Note unless
      the
      Holder first physically surrenders this Note to the Borrower, whereupon the
      Borrower will forthwith issue and deliver upon the order of the Holder a new
      Note of like tenor, registered as the Holder (upon payment by the Holder of
      any
      applicable transfer taxes) may request, representing in the aggregate the
      remaining unpaid principal amount of this Note.  The Holder and any
      assignee, by acceptance of this Note, acknowledge and agree that, by reason
      of
      the provisions of this paragraph, following conversion of a portion of this
      Note, the unpaid and unconverted principal amount of this Note represented
      by
      this Note may be less than the amount stated on the face hereof.

     

    (c)  Payment
      of Taxes.  The Borrower shall not be
      required to pay any tax which may be payable in respect of any transfer involved
      in the issue and delivery of shares of Common Stock or other securities or
      property on conversion of this Note in a name other than that of the Holder
      (or
      in street name), and the Borrower shall not be required to issue or deliver
      any
      such shares or other securities or property unless and until the person or
      persons (other than the Holder or the custodian in whose street name such shares
      are to be held for the Holder’s account) requesting the issuance thereof shall
      have paid to the Borrower the amount of any such tax or shall have established
      to the satisfaction of the Borrower that such tax has been paid.

     

    (d)  Delivery
      of Common Stock Upon Conversion.  Upon
      receipt by the Borrower from the Holder of a facsimile transmission (or other
      reasonable means of communication) of a Notice of Conversion meeting the
      requirements for conversion as provided in this Section 1.4, the Borrower shall
      issue and deliver or cause to be issued and delivered to or upon the order
      of
      the Holder certificates for the Common Stock issuable upon such conversion
      within three (3) business days after such receipt (and, solely in the case
      of
      conversion of the entire unpaid principal amount hereof, surrender of this
      Note)
      (such third business day being hereinafter referred to as the
“Deadline”) in accordance with the terms hereof and the
      Purchase Agreement (including, without limitation, in accordance with the
      requirements of Section 2(g) of the Purchase Agreement that certificates for
      shares of Common Stock issued on or after the effective date of the Registration
      Statement upon conversion of this Note shall not bear any restrictive
      legend).

     

    (e)  Obligation
      of Borrower to Deliver Common
      Stock.  Upon receipt by the Borrower of
      a Notice of Conversion, the Holder shall be deemed to be the holder of record
      of
      the Common Stock issuable upon such conversion, the outstanding principal amount
      and the amount of accrued and unpaid interest on this Note shall be reduced
      to
      reflect such conversion, and, unless the Borrower defaults on its obligations
      under this Article I, all rights with respect to the portion of this Note being
      so converted shall forthwith terminate except the right to receive the Common
      Stock or other securities, cash or other assets, as herein provided, on such
      conversion.  If the Holder shall have given a Notice of Conversion as
      provided herein, the Borrower’s obligation to issue and deliver the certificates
      for Common Stock shall be absolute and unconditional, irrespective of the
      absence of any action by the Holder to enforce the same, any waiver or consent
      with respect to any provision thereof, the recovery of any judgment against
      any
      person or any action to enforce the same, any failure or delay in the
      enforcement of any other obligation of the Borrower to the holder of record,
      or
      any setoff, counterclaim, recoupment, limitation or termination, or any breach
      or alleged breach by the Holder of any obligation to the Borrower, and
      irrespective of any other circumstance which might otherwise limit such
      obligation of the Borrower to the Holder in connection with such
      conversion.  The Conversion Date specified in the Notice of Conversion
      shall be the Conversion Date so long as the Notice of Conversion is received
      by
      the Borrower before 6:00 p.m., New York, New York time, on such
      date.

     

    (f)  Delivery
      of Common Stock by Electronic
      Transfer.  In lieu of delivering
      physical certificates representing the Common Stock issuable upon conversion,
      provided the Borrower’s transfer agent is participating in the Depository Trust
      Company (“DTC”) Fast Automated Securities Transfer
      (“FAST”) program, upon request of the Holder and its compliance
      with the provisions contained in Section 1.1 and in this Section 1.4, the
      Borrower shall use its best efforts to cause its transfer agent to
      electronically transmit the Common Stock issuable upon conversion to the Holder
      by crediting the account of Holder’s Prime Broker with DTC through its Deposit
      Withdrawal Agent Commission (“DWAC”) system.

     

    (g)  Failure
      to Deliver Common Stock Prior to
      Deadline.  Without in any way limiting
      the Holder’s right to pursue other remedies, including actual damages and/or
      equitable relief, the parties agree that if delivery of the Common Stock
      issuable upon conversion of this Note is more than two (2) business days after
      the Deadline (other than a failure due to the circumstances described in Section
      1.3 above, which failure shall be governed by such Section) the Borrower shall
      pay to the Holder $2,000 per day in cash, for each day beyond the Deadline
      that
      the Borrower fails to deliver such Common Stock.  Such cash amount
      shall be paid to Holder by the fifth day of the month following the month in
      which it has accrued or, at the option of the Holder (by written notice to
      the
      Borrower by the first day of the month following the month in which it has
      accrued), shall be added to the principal amount of this Note, in which event
      interest shall accrue thereon in accordance with the terms of this Note and
      such
      additional principal amount shall be convertible into Common Stock in accordance
      with the terms of this Note.

     

    1.5  Concerning
      the Shares.  The shares of Common Stock
      issuable upon conversion of this Note may not be sold or transferred
      unless  (i) such shares are sold pursuant to an effective registration
      statement under the Act or (ii) the Borrower or its transfer agent shall have
      been furnished with an opinion of  counsel (which opinion shall be in
      form, substance and scope customary for opinions of counsel in comparable
      transactions) to the effect that the shares to be sold or transferred may be
      sold or transferred pursuant to an exemption from such registration or
      (iii) such shares are sold or transferred pursuant to Rule 144 under the
      Act (or a successor rule) (“Rule 144”) or (iv) such shares are
      transferred to an “affiliate” (as defined in Rule 144) of the Borrower who
      agrees to sell or otherwise transfer the shares only in accordance with this
      Section 1.5 and who is an Accredited Investor (as defined in the Purchase
      Agreement).  Except as otherwise provided in the Purchase Agreement
      (and subject to the removal provisions set forth below), until such time as
      the
      shares of Common Stock issuable upon conversion of this Note have been
      registered under the Act as contemplated by the Registration Rights Agreement
      or
      otherwise may be sold pursuant to Rule 144 without any restriction as to the
      number of securities as of a particular date that can then be immediately sold,
      each certificate for shares of Common Stock issuable upon conversion of this
      Note that has not been so included in an effective registration statement or
      that has not been sold pursuant to an effective registration statement or an
      exemption that permits removal of the legend, shall bear a legend substantially
      in the following form, as appropriate:

     

    “THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED.  THE SECURITIES MAY NOT BE SOLD,
      TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
      FOR THE SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE
      AND SCOPE CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT
      REGISTRATION IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144
      OR
      REGULATION S UNDER SAID ACT.”

     

    The
      legend set forth above shall be removed and the Borrower shall issue to the
      Holder a new certificate therefor free of any transfer legend if (i) the
      Borrower or its transfer agent shall have received an opinion of counsel, in
      form, substance and scope customary for opinions of counsel in comparable
      transactions, to the effect that a public sale or transfer of such Common Stock
      may be made without registration under the Act and the shares are so sold or
      transferred, (ii) such Holder provides the Borrower or its transfer agent with
      reasonable assurances that the Common Stock issuable upon conversion of this
      Note (to the extent such securities are deemed to have been acquired on the
      same
      date) can be sold pursuant to Rule 144 or (iii) in the case of the Common Stock
      issuable upon conversion of this Note, such security is registered for sale
      by
      the Holder under an effective registration statement filed under the Act or
      otherwise may be sold pursuant to Rule 144 without any restriction as to the
      number of securities as of a particular date that can then be immediately
      sold.  Nothing in this Note shall (i) limit the Borrower’s obligation
      under the Registration Rights Agreement or (ii) affect in any way the Holder’s
      obligations to comply with applicable prospectus delivery requirements upon
      the
      resale of the securities referred to herein.

     

    1.6  Effect
      of Certain Events.

     

    (a)  Effect
      of Merger, Consolidation, Etc.  At the
      option of the Holder, the sale, conveyance or disposition of all or
      substantially all of the assets of the Borrower, the effectuation by the
      Borrower of a transaction or series of related transactions in which more than
      50% of the voting power of the Borrower is disposed of, or the consolidation,
      merger or other business combination of the Borrower with or into any other
      Person (as defined below) or Persons when the Borrower is not the survivor
      shall
      either:  (i) be deemed to be an Event of Default (as defined in
      Article III) pursuant to which the Borrower shall be required to pay to the
      Holder upon the consummation of and as a condition to such transaction an amount
      equal to the Default Amount (as defined in Article III) or (ii) be treated
      pursuant to Section 1.6(b) hereof.  “Person” shall
      mean any individual, corporation, limited liability company, partnership,
      association, trust or other entity or organization.

     

    (b)  Adjustment
      Due to Merger, Consolidation, Etc.  If,
      at any time when this Note is issued and outstanding and prior to conversion
      of
      all of the Notes, there shall be any merger, consolidation, exchange of shares,
      recapitalization, reorganization, or other similar event, as a result of which
      shares of Common Stock of the Borrower shall be changed into the same or a
      different number of shares of another class or classes of stock or securities
      of
      the Borrower or another entity, or in case of any sale or conveyance of all
      or
      substantially all of the assets of the Borrower other than in connection with
      a
      plan of complete liquidation of the Borrower, then the Holder of this Note
      shall
      thereafter have the right to receive upon conversion of this Note, upon the
      basis and upon the terms and conditions specified herein and in lieu of the
      shares of Common Stock immediately theretofore issuable upon conversion, such
      stock, securities or assets which the Holder would have been entitled to receive
      in such transaction had this Note been converted in full immediately prior
      to
      such transaction (without regard to any limitations on conversion set forth
      herein), and in any such case appropriate provisions shall be made with respect
      to the rights and interests of the Holder of this Note to the end that the
      provisions hereof (including, without limitation, provisions for adjustment
      of
      the Conversion Price and of the number of shares issuable upon conversion of
      the
      Note) shall thereafter be applicable, as nearly as may be practicable in
      relation to any securities or assets thereafter deliverable upon the conversion
      hereof.  The Borrower shall not effect any transaction described in
      this Section 1.6(b) unless (a) it first gives, to the extent practicable, thirty
      (30) days prior written notice (but in any event at least fifteen (15) days
      prior written notice) of the record date of the special meeting of shareholders
      to approve, or if there is no such record date, the consummation of, such
      merger, consolidation, exchange of shares, recapitalization, reorganization
      or
      other similar event or sale of assets (during which time the Holder shall be
      entitled to convert this Note) and (b) the resulting successor or acquiring
      entity (if not the Borrower) assumes by written instrument the obligations
      of
      this Section 1.6(b).  The above provisions shall similarly apply to
      successive consolidations, mergers, sales, transfers or share
      exchanges.

     

    (c)  Adjustment
      Due to Distribution.  If the Borrower
      shall declare or make any distribution of its assets (or rights to acquire
      its
      assets) to holders of Common Stock as a dividend, stock repurchase, by way
      of
      return of capital or otherwise (including any dividend or distribution to the
      Borrower’s shareholders in cash or shares (or rights to acquire shares) of
      capital stock of a subsidiary (i.e., a spin-off)) (a
“Distribution”), then the Holder of this Note shall be
      entitled, upon any conversion of this Note after the date of record for
      determining shareholders entitled to such Distribution, to receive the amount
      of
      such assets which would have been payable to the Holder with respect to the
      shares of Common Stock issuable upon such conversion had such Holder been the
      holder of such shares of Common Stock on the record date for the determination
      of shareholders entitled to such Distribution.

     

    (d)  Adjustment
      Due to Dilutive Issuance.  If, at any
      time when any Notes are issued and outstanding, the Borrower issues or sells,
      or
      in accordance with this Section 1.6(d) hereof is deemed to have issued or sold,
      any shares of Common Stock for no consideration or for a consideration per
      share
      (before deduction of reasonable expenses or commissions or underwriting
      discounts or allowances in connection therewith) less than the Fixed Conversion
      Price in effect on the date of such issuance (or deemed issuance) of such shares
      of Common Stock (a “Dilutive Issuance”), then immediately upon
      the Dilutive Issuance, the Variable Conversion Price will be reduced to the
      amount of the consideration per share received by the Borrower in such Dilutive
      Issuance; provided that only one adjustment will be made for each
      Dilutive Issuance.

     

    The
      Borrower shall be deemed to have issued or sold shares of Common Stock if the
      Borrower in any manner issues or grants any warrants, rights or options (not
      including employee stock option plans), whether or not immediately exercisable,
      to subscribe for or to purchase Common Stock or other securities convertible
      into or exchangeable for Common Stock (“Convertible
      Securities”) (such warrants, rights and options to purchase Common
      Stock or Convertible Securities are hereinafter referred to as
“Options”) and the price per share for which Common Stock is
      issuable upon the exercise of such Options is less than the Variable Conversion
      Price then in effect, then the Variable Conversion Price shall be equal to
      such
      price per share.  For purposes of the preceding sentence, the “price
      per share for which Common Stock is issuable upon the exercise of such Options”
is determined by dividing (i) the total amount, if any, received or receivable
      by the Borrower as consideration for the issuance or granting of all such
      Options, plus the minimum aggregate amount of additional consideration, if
      any,
      payable to the Borrower upon the exercise of all such Options, plus, in the
      case
      of Convertible Securities issuable upon the exercise of such Options, the
      minimum aggregate amount of additional consideration payable upon the conversion
      or exchange thereof at the time such Convertible Securities first become
      convertible or exchangeable, by (ii) the maximum total number of shares of
      Common Stock issuable upon the exercise of all such Options (assuming full
      conversion of Convertible Securities, if applicable).  No further
      adjustment to the Conversion Price will be made upon the actual issuance of
      such
      Common Stock upon the exercise of such Options or upon the conversion or
      exchange of Convertible Securities issuable upon exercise of such
      Options.

     

    Additionally,
      the Borrower shall be deemed to have issued or sold shares of Common Stock
      if
      the Borrower in any manner issues or sells any Convertible Securities, whether
      or not immediately convertible (other than where the same are issuable upon
      the
      exercise of Options), and the price per share for which Common Stock is issuable
      upon such conversion or exchange is less than the Variable Conversion Price
      then
      in effect, then the Variable Conversion Price shall be equal to such price
      per
      share.  For the purposes of the preceding sentence, the “price per
      share for which Common Stock is issuable upon such conversion or exchange” is
      determined by dividing (i) the total amount, if any, received or receivable
      by
      the Borrower as consideration for the issuance or sale of all such Convertible
      Securities, plus the minimum aggregate amount of additional consideration,
      if
      any, payable to the Borrower upon the conversion or exchange thereof at the
      time
      such Convertible Securities first become convertible or exchangeable, by (ii)
      the maximum total number of shares of Common Stock issuable upon the conversion
      or exchange of all such Convertible Securities.  No further adjustment
      to the Variable Conversion Price will be made upon the actual issuance of such
      Common Stock upon conversion or exchange of such Convertible
      Securities.

     

    (e)  Purchase
      Rights.  If, at any time when any Notes
      are issued and outstanding, the Borrower issues any convertible securities
      or
      rights to purchase stock, warrants, securities or other property (the
“Purchase Rights”) pro rata to the record holders of any class
      of Common Stock, then the Holder of this Note will be entitled to acquire,
      upon
      the terms applicable to such Purchase Rights, the aggregate Purchase Rights
      which such Holder could have acquired if such Holder had held the number of
      shares of Common Stock acquirable upon complete conversion of this Note (without
      regard to any limitations on conversion contained herein) immediately before
      the
      date on which a record is taken for the grant, issuance or sale of such Purchase
      Rights or, if no such record is taken, the date as of which the record holders
      of Common Stock are to be determined for the grant, issue or sale of such
      Purchase Rights.

     

    (f)  Notice
      of Adjustments.  Upon the occurrence of
      each adjustment or readjustment of the Conversion Price as a result of the
      events described in this Section 1.6, the Borrower, at its expense, shall
      promptly compute such adjustment or readjustment and prepare and furnish to
      the
      Holder of a certificate setting forth such adjustment or readjustment and
      showing in detail the facts upon which such adjustment or readjustment is
      based.  The Borrower shall, upon the written request at any time of
      the Holder, furnish to such Holder a like certificate setting forth (i) such
      adjustment or readjustment, (ii) the Conversion Price at the time in effect
      and
      (iii) the number of shares of Common Stock and the amount, if any, of other
      securities or property which at the time would be received upon conversion
      of
      the Note.

     

    1.7  Trading
      Market Limitations. Unless permitted by the
      applicable rules and regulations of the principal securities market on which
      the
      Common Stock is then listed or traded, in no event shall the Borrower issue
      upon
      conversion of or otherwise pursuant to this Note and the other Notes issued
      pursuant to the Purchase Agreement more than the maximum number of shares of
      Common Stock that the Borrower can issue pursuant to any rule of the principal
      United States securities market on which the Common Stock is then traded (the
      “Maximum Share Amount”), which shall be 19.99% of the total
      shares outstanding on the Closing Date (as defined in the Purchase Agreement),
      subject to equitable adjustment from time to time for stock splits, stock
      dividends, combinations, capital reorganizations and similar events relating
      to
      the Common Stock occurring after the date hereof.  Once the Maximum
      Share Amount has been issued (the date of which is hereinafter referred to
      as
      the “Maximum Conversion Date”), if the Borrower fails to
      eliminate any prohibitions under applicable law or the rules or regulations
      of
      any stock exchange, interdealer quotation system or other self-regulatory
      organization with jurisdiction over the Borrower or any of its securities on
      the
      Borrower’s ability to issue shares of Common Stock in excess of the Maximum
      Share Amount (a “Trading Market Prepayment Event”), in lieu of
      any further right to convert this Note, and in full satisfaction of the
      Borrower’s obligations under this Note, the Borrower shall pay to the Holder,
      within fifteen (15) business days of the Maximum Conversion Date (the
“Trading Market Prepayment Date”), an amount equal to 130%
times the sum of (a) the then outstanding principal amount
      of this
      Note immediately following the Maximum Conversion Date, plus (b) accrued
      and unpaid interest on the unpaid principal amount of this Note to the Trading
      Market Prepayment Date, plus (c) Default Interest, if any, on the amounts
      referred to in clause (a) and/or (b) above, plus (d) any optional amounts
      that may be added thereto at the Maximum Conversion Date by the Holder in
      accordance with the terms hereof (the then outstanding principal amount of
      this
      Note immediately following the Maximum Conversion Date, plus the amounts
      referred to in clauses (b), (c) and (d) above shall collectively be referred
      to
      as the “Remaining Convertible Amount”).  With respect
      to each Holder of Notes, the Maximum Share Amount shall refer to such Holder’s
prorata share thereof determined in accordance with Section 4.8
      below.  In the event that the sum of (x) the aggregate number of
      shares of Common Stock issued upon conversion of this Note and the other Notes
      issued pursuant to the Purchase Agreement plus (y) the aggregate number
      of shares of Common Stock that remain issuable upon conversion of this Note
      and
      the other Notes issued pursuant to the Purchase Agreement, represents at least
      one hundred percent (100%) of the Maximum Share Amount (the “Triggering
      Event”), the Borrower will use its best efforts to seek and obtain
      Shareholder Approval (or obtain such other relief as will allow conversions
      hereunder in excess of the Maximum Share Amount) as soon as practicable
      following the Triggering Event and before the Maximum Conversion
      Date.  As used herein, “Shareholder Approval” means
      approval by the shareholders of the Borrower to authorize the issuance of the
      full number of shares of Common Stock which would be issuable upon full
      conversion of the then outstanding Notes but for the Maximum Share
      Amount.

     

    1.8  Status
      as Shareholder.  Upon submission of a
      Notice of Conversion by a Holder, (i) the shares covered thereby (other than
      the
      shares, if any, which cannot be issued because their issuance would exceed
      such
      Holder’s allocated portion of the Reserved Amount or Maximum Share Amount) shall
      be deemed converted into shares of Common Stock and (ii) the Holder’s rights as
      a Holder of such converted portion of this Note shall cease and terminate,
      excepting only the right to receive certificates for such shares of Common
      Stock
      and to any remedies provided herein or otherwise available at law or in equity
      to such Holder because of a failure by the Borrower to comply with the
      terms  of this Note.  Notwithstanding the foregoing, if a
      Holder has not received certificates for all shares of Common Stock prior to
      the
      tenth (10th) business day after the expiration of the Deadline with respect
      to a
      conversion of any portion of this Note for any reason, then (unless the Holder
      otherwise elects to retain its status as a holder of Common Stock by so
      notifying the Borrower) the Holder shall regain the rights of a Holder of this
      Note with respect to such unconverted portions of this Note and the Borrower
      shall, as soon as practicable, return such unconverted Note to the Holder or,
      if
      the Note has not been surrendered, adjust its records to reflect that such
      portion of this Note has not been converted.  In all cases, the Holder
      shall retain all of its rights and remedies (including, without limitation,
      (i)
      the right to receive Conversion Default Payments pursuant to Section 1.3 to
      the
      extent required thereby for such Conversion Default and any subsequent
      Conversion Default and (ii) the right to have the Conversion Price with respect
      to subsequent conversions determined in accordance with Section 1.3) for the
      Borrower’s failure to convert this Note.

     

     

    ARTICLE
      II.     CERTAIN COVENANTS

     

    2.1  Distributions
      on Capital Stock.  So long as the
      Borrower shall have any obligation under this Note, the Borrower shall not
      without the Holder’s written consent (a) pay, declare or set apart for such
      payment, any dividend or other distribution (whether in cash, property or other
      securities) on shares of capital stock other than dividends on shares of Common
      Stock solely in the form of additional shares of Common Stock or (b) directly
      or
      indirectly or through any subsidiary make any other payment or distribution
      in
      respect of its capital stock except for distributions pursuant to any
      shareholders’ rights plan which is approved by a majority of the Borrower’s
      disinterested directors.

     

    2.2  Restriction
      on Stock Repurchases.  So long as the
      Borrower shall have any obligation under this Note, the Borrower shall not
      without the Holder’s written consent redeem, repurchase or otherwise acquire
      (whether for cash or in exchange for property or other securities or otherwise)
      in any one transaction or series of related transactions any shares of capital
      stock of the Borrower or any warrants, rights or options to purchase or acquire
      any such shares.

     

    2.3  Borrowings.  So
      long as the Borrower shall have any obligation under this Note, the Borrower
      shall not, without the Holder’s written consent, create, incur, assume or suffer
      to exist any liability for borrowed money, except (a) borrowings in existence
      or
      committed on the date hereof and of which the Borrower has informed Holder
      in
      writing prior to the date hereof, (b) indebtedness to trade creditors or
      financial institutions incurred in the ordinary course of business or (c)
      borrowings, the proceeds of which shall be used to repay this Note.

     

    2.4  Sale
      of Assets.  So long as the Borrower
      shall have any obligation under this Note, the Borrower shall not, without
      the
      Holder’s written consent, sell, lease or otherwise dispose of any significant
      portion of its assets outside the ordinary course of business.  Any
      consent to the disposition of any assets may be conditioned on a specified
      use
      of the proceeds of disposition.

     

    2.5  Advances
      and Loans.  So long as the Borrower
      shall have any obligation under this Note, the Borrower shall not, without
      the
      Holder’s written consent, lend money, give credit or make advances to any
      person, firm, joint venture or corporation, including, without limitation,
      officers, directors, employees, subsidiaries and affiliates of the Borrower,
      except loans, credits or advances (a) in existence or committed on the date
      hereof and which the Borrower has informed Holder in writing prior to the date
      hereof, (b) made in the ordinary course of business or (c) not in excess of
      $50,000.

     

    2.6  Contingent
      Liabilities.  So long as the Borrower
      shall have any obligation under this Note, the Borrower shall not, without
      the
      Holder’s written consent, which shall not be unreasonably withheld, assume,
      guarantee, endorse, contingently agree to purchase or otherwise become liable
      upon the obligation of any person, firm, partnership, joint venture or
      corporation, except by the endorsement of negotiable instruments for deposit
      or
      collection and except assumptions, guarantees, endorsements and contingencies
      (a) in existence or committed on the date hereof and which the Borrower has
      informed Holder in writing prior to the date hereof, and (b) similar
      transactions in the ordinary course of business.

     

     

    ARTICLE
      III.     EVENTS OF DEFAULT

     

    If
      any of
      the following events of default (each, an “Event of Default”)
      shall occur:

     

    3.1  Failure
      to Pay Principal or Interest.  The
      Borrower fails to pay the principal hereof or interest thereon when due on
      this
      Note, whether at maturity, upon a Trading Market Prepayment Event pursuant
      to
      Section 1.7, upon acceleration or otherwise;

     

    3.2  Conversion
      and the Shares.  The Borrower fails to
      issue shares of Common Stock to the Holder (or announces or threatens that
      it
      will not honor its obligation to do so) upon exercise by the Holder of the
      conversion rights of the Holder in accordance with the terms of this Note (for
      a
      period of at least sixty (60) days, if such failure is solely as a result of

      specified in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 3.9, or 3.10, at the option
      of the Holders of a majority of the aggregate principal amount of the
      outstanding Notes issued pursuant to the Purchase Agreement exercisable through
      the delivery of written notice to the Borrower by such Holders (the
“Default Notice”), and upon the occurrence of an Event of

      of this Note to the date of payment (the “Mandatory Prepayment
      Date”) plus (y) Default Interest, if any, on the amounts

      Holder pursuant to Sections 1.3 and 1.4(g) hereof or pursuant to Section 2(c)
      of
      the Registration Rights Agreement (the then outstanding principal amount of
      this
      Note to the date of payment plus the amounts referred to in clauses (x),
      (y) and (z) shall collectively be known as the “Default Sum”)
      or (ii) the “parity value” of the Default Sum to be prepaid, where parity value
      means (a) the highest number of shares of Common Stock issuable upon conversion
      of or otherwise pursuant to such Default Sum in accordance with Article I,
      treating the Trading Day immediately preceding the Mandatory Prepayment Date
      as
      the “Conversion Date” for purposes of determining the lowest applicable
      Conversion Price, unless the Default Event arises as a result of a breach in
      respect of a specific Conversion Date in which case such Conversion Date shall
      be the Conversion Date), multiplied by (b) the highest Closing Price for
      the Common Stock during the period beginning on the date of first occurrence
      of
      the Event of Default and ending one day prior to the Mandatory Prepayment Date
      (the “Default Amount”) and all other amounts payable hereunder
      shall immediately become due and payable, all without demand, presentment or
      notice, all of which hereby are expressly waived, together with all costs,
      including, without limitation, legal fees and expenses, of collection, and
      the
      Holder shall be entitled to exercise all other rights and remedies available
      at
      law or in equity.  If the Borrower fails to pay the Default Amount
      within five (5) business days of written notice that such amount is due and
      payable, then the Holder shall have the right at any time, so long as the
      Borrower remains in default (and so long and to the extent that there are
      sufficient authorized shares), to require the Borrower, upon written notice,
      to
      immediately issue, in lieu of the Default Amount, the number of shares of Common
      Stock of the Borrower equal to the Default Amount divided by the Conversion
      Price then in effect.

    4.1  Failure
      or Indulgence Not Waiver.  No failure or
      delay on the part of the Holder in the exercise of any power, right or privilege
      hereunder shall operate as a waiver thereof, nor shall any single or partial
      exercise of any such power, right or privilege preclude other or further
      exercise thereof or of any other right, power or privileges.  All
      rights and remedies existing hereunder are cumulative to, and not exclusive
      of,
      any rights or remedies otherwise available.

    4.3  Amendments.  This
      Note and any provision hereof may only be amended by an instrument in writing
      signed by the Borrower and the Holder.  The term “Note” and all
      reference thereto, as used throughout this instrument, shall mean this
      instrument (and the other Notes issued pursuant to the Purchase Agreement)
      as
      originally executed, or if later amended or supplemented, then as so amended
      or
      supplemented.

     

    4.4  Assignability.  This
      Note shall be binding upon the Borrower and its successors and assigns, and
      shall inure to be the benefit of the Holder and its successors and
      assigns.  Each transferee of this Note must be an “accredited
      investor” (as defined in Rule 501(a) of the 1933
      Act).  Notwithstanding anything in this Note to the contrary, this
      Note may be pledged as collateral in connection with a bonafide
      margin account or other lending arrangement.

     

    4.5  Cost
      of Collection.  If default is made in
      the payment of this Note, the Borrower shall pay the Holder hereof costs of
      collection, including reasonable attorneys’ fees.

     

    4.6  Governing
      Law.  THIS NOTE SHALL BE ENFORCED,
      GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK
      APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE,
      WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS.  THE BORROWER
      HEREBY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES FEDERAL COURTS
      LOCATED IN NEW YORK, NEW YORK WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS
      NOTE, THE AGREEMENTS ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS
      CONTEMPLATED HEREBY OR THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE
      OF AN
      INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR
      PROCEEDING.  BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A
      PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE
      SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR
      PROCEEDING.  NOTHING HEREIN SHALL AFFECT EITHER PARTY’S RIGHT TO SERVE
      PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.  BOTH PARTIES AGREE THAT
      A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR PROCEEDING SHALL BE
      CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT
      OR IN ANY OTHER LAWFUL MANNER.  THE PARTY WHICH DOES NOT PREVAIL IN
      ANY DISPUTE ARISING UNDER THIS NOTE SHALL BE RESPONSIBLE FOR ALL FEES AND
      EXPENSES, INCLUDING ATTORNEYS’ FEES, INCURRED BY THE PREVAILING PARTY IN
      CONNECTION WITH SUCH DISPUTE.

     

    4.7  Certain
      Amounts.  Whenever pursuant to this Note
      the Borrower is required to pay an amount in excess of the outstanding principal
      amount (or the portion thereof required to be paid at that time) plus accrued
      and unpaid interest plus Default Interest on such interest, the Borrower and
      the
      Holder agree that the actual damages to the Holder from the receipt of cash
      payment on this Note may be difficult to determine and the amount to be so
      paid
      by the Borrower represents stipulated damages and not a penalty and is intended
      to compensate the Holder in part for loss of the opportunity to convert this
      Note and to earn a return from the sale of shares of Common Stock acquired
      upon
      conversion of this Note at a price in excess of the price paid for such shares
      pursuant to this Note.  The Borrower and the Holder hereby agree that
      such amount of stipulated damages is not plainly disproportionate to the
      possible loss to the Holder from the receipt of a cash payment without the
      opportunity to convert this Note into shares of Common Stock.

     

    4.8  Allocations
      of Maximum Share Amount and Reserved
      Amount.  The Maximum Share Amount and
      Reserved Amount shall be allocated pro rata among the Holders of Notes based
      on
      the principal amount of such Notes issued to each Holder.  Each
      increase to the Maximum Share Amount and Reserved Amount shall be allocated
      pro
      rata among the Holders of Notes based on the principal amount of such Notes
      held
      by each Holder at the time of the increase in the Maximum Share Amount or
      Reserved Amount.  In the event a Holder shall sell or otherwise
      transfer any of such Holder’s Notes, each transferee shall be allocated a pro
      rata portion of such transferor’s Maximum Share Amount and Reserved
      Amount.  Any portion of the Maximum Share Amount or Reserved Amount
      which remains allocated to any person or entity which does not hold any Notes
      shall be allocated to the remaining Holders of Notes, pro rata based on the
      principal amount of such Notes then held by such Holders.

     

    4.9  Damages
      Shares.  The shares of Common Stock that
      may be issuable to the Holder pursuant to Sections 1.3 and 1.4(g) hereof and
      pursuant to Section 2(c) of the Registration Rights Agreement (“Damages
      Shares”) shall be treated as Common Stock issuable upon conversion of
      this Note for all purposes hereof and shall be subject to all of the limitations
      and afforded all of the rights of the other shares of Common Stock issuable
      hereunder, including without limitation, the right to be included in the
      Registration Statement filed pursuant to the Registration Rights
      Agreement.  For purposes of calculating interest payable on the
      outstanding principal amount hereof, except as otherwise provided herein,
      amounts convertible into Damages Shares (“Damages Amounts”)
      shall not bear interest but must be converted prior to the conversion of any
      outstanding principal amount hereof, until the outstanding Damages Amounts
      is
      zero.

     

    4.10  Denominations.  At
      the request of the Holder, upon surrender of this Note, the Borrower shall
      promptly issue new Notes in the aggregate outstanding principal amount hereof,
      in the form hereof, in such denominations of at least $50,000 as the Holder
      shall request.

     

    4.11  Purchase
      Agreement.  By its acceptance of this
      Note, each Holder agrees to be bound by the applicable terms of the Purchase
      Agreement.

     

    4.12  Notice
      of Corporate Events.  Except as
      otherwise provided below, the Holder of this Note shall have no rights as a
      Holder of Common Stock unless and only to the extent that it converts this
      Note
      into Common Stock.  The Borrower shall provide the Holder with prior
      notification of any meeting of the Borrower’s shareholders (and copies of proxy
      materials and other information sent to shareholders).  In the event
      of any taking by the Borrower of a record of its shareholders for the purpose
      of
      determining shareholders who are entitled to receive payment of any dividend
      or
      other distribution, any right to subscribe for, purchase or otherwise acquire
      (including by way of merger, consolidation, reclassification or
      recapitalization) any share of any class or any other securities or property,
      or
      to receive any other right, or for the purpose of determining shareholders
      who
      are entitled to vote in connection with any proposed sale, lease or conveyance
      of all or substantially all of the assets of the Borrower or any proposed
      liquidation, dissolution or winding up of the Borrower, the Borrower shall
      mail
      a notice to the Holder, at least twenty (20) days prior to the record date
      specified therein (or thirty (30) days prior to the consummation of the
      transaction or event, whichever is earlier), of the date on which any such
      record is to be taken for the purpose of such dividend, distribution, right
      or
      other event, and a brief statement regarding the amount and character of such
      dividend, distribution, right or other event to the extent known at such
      time.  The Borrower shall make a public announcement of any event
      requiring notification to the Holder hereunder substantially simultaneously
      with
      the notification to the Holder in accordance with the terms of this Section
      4.12.

     

    4.13  Remedies.  The
      Borrower acknowledges that a breach by it of its obligations hereunder will
      cause irreparable harm to the Holder, by vitiating the intent and purpose of
      the
      transaction contemplated hereby.  Accordingly, the Borrower
      acknowledges that the remedy at law for a breach of its obligations under this
      Note will be inadequate and agrees, in the event of a breach or threatened
      breach by the Borrower of the provisions of this Note, that the Holder shall
      be
      entitled, in addition to all other available remedies at law or in equity,
      and
      in addition to the penalties assessable herein, to an injunction or injunctions
      restraining, preventing or curing any breach of this Note and to enforce
      specifically the terms and provisions thereof, without the necessity of showing
      economic loss and without any bond or other security being
      required.

    5.1  Call
      Option.  Notwithstanding anything to the
      contrary contained in this Article V, so long as (i) no Event of Default or
      Trading Market Prepayment Event shall have occurred and be continuing,
      (ii) the Borrower has a sufficient number of authorized shares of Common
      Stock reserved for issuance upon full conversion of the Notes, then at any
      time
      after the Issue Date, and (iii) the Common Stock is trading at or below
      $.25 per share, the Borrower shall have the right, exercisable on not less
      than
      ten (10) Trading Days prior written notice to the Holders of the Notes (which
      notice may not be sent to the Holders of the Notes until the Borrower is
      permitted to prepay the Notes pursuant to this Section 5.1), to prepay all
      of
      the outstanding Notes in accordance with this Section 5.1.  Any notice
      of prepayment hereunder (an “Optional Prepayment”) shall be
      delivered to the Holders of the Notes at their registered addresses appearing
      on
      the books and records of the Borrower and shall state (1) that the Borrower
      is
      exercising its right to prepay all of the Notes issued on the Issue Date and
      (2)
      the date of prepayment (the “Optional Prepayment
      Notice”).  On the date fixed for prepayment (the
“Optional Prepayment Date”), the Borrower shall make payment of
      the Optional Prepayment Amount (as defined below) to or upon the order of the
      Holders as specified by the Holders in writing to the Borrower at least one
      (1)
      business day prior to the Optional Prepayment Date.  If the Borrower
      exercises its right to prepay the Notes, the Borrower shall make payment to
      the
      holders of an amount in cash (the “Optional Prepayment Amount”)
      equal to either (i) 120% (for prepayments occurring within thirty (30) days
      of the Issue Date), (ii) 125% for prepayments occurring between thirty-one
      (31) and sixty  (60) days of the Issue Date, or (iii) 135% (for
      prepayments occurring after the sixtieth (60th) day following
      the
      Issue Date), multiplied by the sum of (w) the then outstanding principal amount
      of this Note plus (x) accrued and unpaid interest on the unpaid
      principal amount of this Note to the Optional Prepayment Date plus (y)
      Default Interest, if any, on the amounts referred to in clauses (w) and (x)
      plus (z) any amounts owed to the Holder pursuant to Sections 1.3 and
      1.4(g) hereof or pursuant to Section 2(c) of the Registration Rights Agreement
      (the then outstanding principal amount of this Note to the date of payment
      plus the amounts referred to in clauses (x), (y) and (z) shall
      collectively be known as the “Optional Prepayment Sum”).
      Notwithstanding notice of an Optional Prepayment, the Holders shall at all
      times
      prior to the Optional Prepayment Date maintain the right to convert all or
      any
      portion of the Notes in accordance with Article I and any portion of Notes
      so
      converted after receipt of an Optional Prepayment Notice and prior to the
      Optional Prepayment Date set forth in such notice and payment of the aggregate
      Optional Prepayment Amount shall be deducted from the principal amount of Notes
      which are otherwise subject to prepayment pursuant to such notice.  If
      the Borrower delivers an Optional Prepayment Notice and fails to pay the
      Optional Prepayment Amount due to the Holders of the Notes within two (2)
      business days following the Optional Prepayment Date, the Borrower shall forever
      forfeit its right to redeem the Notes pursuant to this Section 5.1.

     

    5.2  Partial
      Call Option.  Notwithstanding anything to the contrary
      contained in this Article V, in the event that the Average Daily Price of the
      Common Stock, as reported by the Reporting Service, for each day of the month
      ending on any Determination Date is below the Initial Market Price, the Borrower
      may, at its option, prepay a portion of the outstanding principal amount of
      the
      Notes equal to 104% of the principal amount hereof divided by thirty-six (36)
      plus one month’s interest.  The term “Initial Market
      Price” means shall mean $.25.
