      prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice
      of conversion in the form attached hereto as Exhibit
      I (the
“ **Conversion

      Company and (B) if required by Section
      3(c)(iii) ,
      surrender this Note to a common carrier for delivery to the Company as soon
      as
      practicable on or following such date (or an indemnification undertaking with
      respect to this Note in the case of its loss, theft or destruction). On or
      before the first (1 st )
      Trading
      Day following the date of receipt of a Conversion Notice, the Company shall
      transmit by facsimile a confirmation of receipt of such Conversion Notice to
      the
      Holder and the Company’s transfer agent (the “ **Transfer
      Agent** ”).
      On or
      before the third (3rd) Trading Day following the date of receipt of a Conversion
      Notice (the “ **Share
      Delivery**  **Date** ”),
      the
      Company shall (x) provided that
      there is an effective Registration Statement and that the Transfer Agent is
      participating in the Depository Trust Company’s (“ **DTC** ”)

      designee’s balance account with DTC through its Deposit Withdrawal Agent
      Commission system or (y) if there is no effective Registration Statement or
      if
      the Transfer Agent is not participating in the DTC Fast Automated Securities
      Transfer Program, issue and deliver to the address as specified in the
      Conversion Notice, a certificate, registered in the name of the Holder or its
      designee, for the number of shares of Common Stock to which the Holder shall
      be
      entitled. If this Note is physically surrendered for conversion as required
      by Section
      3(c)(iii) and the
      outstanding Principal of this Note is greater than the Principal portion of
      the
      Conversion Amount being converted, then the Company shall as soon as practicable
      and in no event later than three (3) Trading Days after receipt of this Note
      and
      at its own expense, issue and deliver to the holder a new Note (in accordance

      entitled to receive the shares of Common Stock issuable upon a conversion of
      this Note shall be treated for all purposes as the record holder or holders
      of
      such shares of Common Stock on the Conversion Date.

(ii)  Company’s
      Failure to Timely Convert . If
      the
      Company shall fail to issue a certificate to the Holder or credit the Holder’s
      balance account with DTC, as applicable, for the number of shares of Common
      Stock to which the Holder is entitled upon conversion of any Conversion Amount
      on or prior to the date which is three (3) Trading Days after the Conversion
      Date (a “ **Conversion
      Failure** ”),
      then
      (A) the Company shall pay damages to the Holder for each Trading Day of such
      Conversion Failure in an amount equal to one and one-half percent (1.5%) of
      the
      product of (1) the sum of the number of shares of Common Stock not issued to
      the
      Holder on or prior to the Share Delivery Date and to which the Holder is
      entitled, and (2) the Weighted Average Price of the Common Stock on the Share
      Delivery Date and (B) the Holder, upon written notice to the Company within
      five
      (5) Trading Days after the Conversion Failure, may void its Conversion Notice
      with respect to, and retain or have returned, as the case may be, any portion
      of
      this Note that has not been converted pursuant to such Conversion Notice; provided that the
      voiding of a Conversion Notice shall not affect the Company’s obligations to
      make any payments which have accrued prior to the date of such notice pursuant
      to this Section
      3(c)(ii) or
      otherwise. In addition to the foregoing, i f
      within
      three (3) Trading Days after the Company’s receipt of the facsimile copy of a
      Conversion Notice the Company shall fail to issue and deliver a certificate
      to
      the Holder or credit the Holder’s balance account with DTC for the number of
      shares of Common Stock to which the Holder is entitled upon such holder’s
      conversion of any Conversion Amount or on any date of the Company’s obligation
      to deliver shares of Common Stock as contemplated pursuant to clause (y) below,
      and if on or after such Trading Day the Holder purchases (in an open market
      transaction or otherwise) Common Stock to deliver in satisfaction of a sale
      by
      the Holder of Common Stock issuable upon such conversion that the Holder
      anticipated receiving from the Company (a “ **Buy-In** ”),
      then
      the Company shall, within three (3) Trading Days after the Holder’s request and
      in the Holder’s discretion, either (x) pay cash to the Holder in an amount equal
      to the Holder’s total purchase price (including brokerage commissions and other
      out of pocket expenses, if any) for the shares of Common Stock so purchased
      (the
“ **Buy-In
      Price** ”),
      at
      which point the Company’s obligation to deliver such certificate (and to issue
      such Common Stock) shall terminate, or (y) promptly honor its obligation to
      deliver to the Holder a certificate or certificates representing such Common
      Stock and pay cash to the Holder in an amount equal to the excess (if any)
      of
      the Buy-In Price over the product of (I) such number of shares of Common Stock,
      times (II) the Weighted Average Price on the Conversion Date.

      the
      principal amount of the Notes held by such holders (the “ **Registered
      Notes** ”).
      The
      entries in the Register shall be conclusive and binding for all purposes absent
      manifest error. The Company and the holders of the Notes shall treat each Person
      whose name is recorded in the Register as the owner of a Note for all purposes,
      including, without limitation, the right to receive payments of Principal and
      Interest hereunder, notwithstanding notice to the contrary. A Registered Note
      may be assigned or sold in whole or in part only by registration of such
      assignment or sale on the Register. Upon its receipt of a request to assign
      or
      sell all or part of any Registered Note by a Holder, the Company shall record
      the information contained therein in the Register and issue one or more new
      Registered Notes in the same aggregate principal amount as the principal amount
      of the surrendered Registered Note to the designated assignee or transferee
      pursuant to Section
      18 .
      Notwithstanding anything to the contrary set forth herein, upon conversion
      of
      any portion of this Note in accordance with the terms hereof, the Holder shall
      not be required to physically surrender this Note to the Company unless (A)
      the
      full Principal amount represented by this Note is being converted or (B) the
      Holder has provided the Company with prior written notice (which notice may
      be
      included in a Conversion Notice) requesting reissuance of this Note upon
      physical surrender of this Note. The Holder and the Company shall maintain
      records showing the Principal, Interest and Late Charges, if any, converted
      and
      the dates of such conversions or shall use such other method, reasonably
      satisfactory to the Holder and the Company, so as not to require physical
      surrender of this Note upon conversion.




(iv)  Pro
      Rata Conversion; Disputes .
      In the
      event that the Company receives a Conversion Notice from more than one holder
      of
      Notes for the same Conversion Date and the Company can convert some, but not
      all, of such portions of the Notes submitted for conversion, the Company,
      subject to Section
      3(d) ,
      shall
      convert from each holder of Notes electing to have Notes converted on such
      date
      a pro rata amount of such holder’s portion of its Notes submitted for conversion
      based on the principal amount of Notes submitted for conversion on such date
      by
      such holder relative to the aggregate principal amount of all Notes submitted
      for conversion on such date. In the event of a dispute as to the number of
      shares of Common Stock issuable to the Holder in connection with a conversion
      of
      this Note, the Company shall issue to the Holder the number of shares of Common
      Stock not in dispute and resolve such dispute in accordance with Section
      23 .

      with Section 3(c) hereof
      at the Conversion Rate as of the Mandatory Conversion Date (as defined below)

(B)  Pro
      Rata Conversion Requirement .
      If the
      Company elects to cause a conversion of any Conversion Amount of this Note
      pursuant to Section
      3(c)(v)(A) ,
      then it
      must to the extent allowable in the Other Notes, simultaneously take the same
      action in the same proportion with respect to the Other Notes. If the Company
      elects a Mandatory Conversion of this Note pursuant to Section
      3(c)(v)(A) (or
      similar provisions under the Other Notes) with respect to less than all of
      the
      Conversion Amounts of the Notes then outstanding, then the Company shall require
      conversion of a Conversion Amount from each of the holders of the Notes equal
      to
      the product of (1) the aggregate Conversion Amount of Notes which the Company
      has elected to cause to be converted pursuant to Section
      3(c)(v)(A) ,
      multiplied by (2) the fraction, the numerator of which is the sum of the
      aggregate Original Principal Amount of the Notes purchased by such holder of
      outstanding Notes and the denominator of which is the sum of the aggregate
      Original Principal Amount of the Notes purchased by all holders holding
      outstanding Notes (such fraction with respect to each holder is referred to
      as
      its “ **Conversion**  **Allocation
      Percentage** ,”
and
      such amount with respect to each holder is referred to as its “ **Pro
      Rata Conversion Amount** ”);
      provided, however, that in the event that any holder’s Pro Rata Conversion
      Amount exceeds the outstanding Principal amount of such holder’s Note, then such
      excess Pro Rata Conversion Amount shall not be converted and no holder shall
      be
      required to convert an amount in excess of its Pro Rata Conversion Amount.
      In
      the event that the initial holder of any Notes shall sell or otherwise transfer
      any of such holder’s Notes, the transferee shall be allocated a pro rata portion
      of such holder’s Conversion Allocation Percentage and the Pro Rata Conversion
      Amount.

      On each
      six month anniversary of the Issuance Date beginning August 15, 2008, the
      Conversion Price shall be adjusted downward to the Reset Reference Price (as
      defined below) if the Weighted Average Price for the twenty (20) consecutive
      Trading Days immediately prior to the applicable six month anniversary (the
      “ **Reset
      Reference Price** ”)
      is
      less than 95% of the Conversion Price in effect as of such applicable six month
      anniversary date, as adjusted pursuant to Section
      7 .
      The
      foregoing notwithstanding, the Conversion Price shall not be reduced pursuant
      to
      this Section
      3(d) to less
      than 80% of the Conversion Price in effect on the Issuance Date, as adjusted
      pursuant to Section
      7(b) ;
      and in
      no event shall the Conversion Price be reduced to less than
      $6.7417.




(e)  Limitations
      on Conversions .




(i)  Beneficial
      Ownership .
      The
      Company shall not effect any conversion of this Note, and the Holder of this
      Note shall not have the right to convert any portion of this Note pursuant
      to Section
      3(a) ,
      to the
      extent that after giving effect to such conversion, the Holder (together with
      the Holder’s affiliates) would beneficially own in excess of 4.99% **** (the
      “ **Maximum
      Percentage** ”)
      of the
      number of shares of Common Stock outstanding immediately after giving effect
      to
      such conversion. For purposes of the foregoing sentence, the number of shares
      of
      Common Stock beneficially owned by the Holder and its affiliates shall include
      the number of shares of Common Stock issuable upon conversion of this Note
      with
      respect to which the determination of such sentence is being made, but shall
      exclude the number of shares of Common Stock which would be issuable upon (A)
      conversion of the remaining, nonconverted portion of this Note beneficially
      owned by the Holder or any of its affiliates and (B) exercise or conversion
      of
      the unexercised or nonconverted portion of any other securities of the Company
      (including, without limitation the Warrants (as defined in the Securities
      Purchase Agreement) and any Other Notes) subject to a limitation on conversion
      or exercise analogous to the limitation contained herein beneficially owned
      by
      the Holder or any of its affiliates. Except as set forth in the preceding
      sentence, for purposes of this Section
      3(e)(i) ,
      beneficial ownership shall be calculated in accordance with Section 13(d) of
      the
      Securities Exchange Act of 1934, as amended (the “ **Exchange
      Act** ”).
      For
      purposes of this Section
      3(e)(i) ,
      in
      determining the number of outstanding shares of Common Stock, the Holder may
      rely on the number of outstanding shares of Common Stock as reflected in (1)
      the
      Company’s most recent Form 10-K, Form 10-Q, Form 8-K or other public filing with
      the SEC, as the case may be, (2) a more recent public announcement by the
      Company or (3) any other notice by the Company or the Transfer Agent setting
      forth the number of shares of Common Stock outstanding. For any reason at any
      time, upon the written or oral request of the Holder, the Company shall within
      one (1) Business Day confirm orally and in writing to the Holder the number
      of
      shares of Common Stock then outstanding. In any case, the number of outstanding
      shares of Common Stock shall be determined after giving effect to the conversion
      or exercise of securities of the Company, including this Note, by the Holder
      or
      its affiliates since the date as of which such number of outstanding shares
      of
      Common Stock was reported. By written notice to the Company, the Holder may
      increase or decrease the Maximum Percentage to any other percentage not in
      excess of 4.99% specified in such notice; provided that (x)
      any such increase will not be effective until the sixty-first (61 st )
      day
      after such notice is delivered to the Company, and (y) any such increase or
      decrease will apply only to the initial Holder and not to any other Holder
      of
      Notes.

(ii)  Mandatory
      Conversion Cap .
      The
      Company shall not effect a Mandatory Conversion of more than twelve percent
      (12%) of the Original Principal Amount of the Notes (with the applicable accrued
      but unpaid Interest and Late Charges on such Conversion Amount) in any six
      month
      period or twenty-four percent (24%) of the Original Principal Amount of the
      Notes (with the applicable accrued but unpaid Interest and Late Charges on
      such
      Conversion Amount) in any twelve (12) month period.




(iii)  Market
      Regulation .
      The
      Company shall not be obligated to issue any shares of Common Stock upon
      conversion of this Note if the issuance of such shares of Common Stock would
      exceed the aggregate number of shares of Common Stock which the Company may
      issue upon conversion of the Notes without breaching the Company’s obligations
      under the rules or regulations of the Principal Market (the “ **Exchange
      Cap** ”),
      except that such limitation shall not apply in the event that the Company (A)
      obtains the approval of its stockholders as required by the applicable rules
      of
      such Principal Market for issuances of Common Stock in excess of such amount
      or
      (B) obtains a written opinion from outside counsel to the Company that such
      approval is not required, which opinion shall be reasonably satisfactory to
      the
      Required Holders. Until such approval or written opinion is obtained, no
      purchaser of the Notes pursuant to the Securities Purchase Agreement (the
“ **Purchasers** ”)
      shall
      be issued in the aggregate, upon conversion of Notes, shares of Common Stock
      in
      an amount greater than the product of the Exchange Cap multiplied by a fraction,
      the numerator of which is the principal amount of Notes issued to a Purchaser
      pursuant to the Securities Purchase Agreement on the Closing Date and the
      denominator of which is the aggregate principal amount of all Notes issued
      to
      the Purchasers pursuant to the Securities Purchase Agreement on the Closing
      Date
      (with respect to each Purchaser, the “ **Exchange
      Cap Allocation** ”).
      In
      the event that any Purchaser shall sell or otherwise transfer any of such
      Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such
      Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence
      shall apply to such transferee with respect to the portion of the Exchange
      Cap
      Allocation allocated to such transferee. In the event that any Holder of Notes
      shall convert all of such Holder’s Notes into a number of shares of Common Stock
      which, in the aggregate, is less than such Holder’s Exchange Cap Allocation,
      then the difference between such Holder’s Exchange Cap Allocation and the number
      of shares of Common Stock actually issued to such Holder shall be allocated
      to
      the respective Exchange Cap Allocations of the remaining Holders of Notes on
      a
      pro rata basis in proportion to the aggregate principal amount of the Notes
      then
      held by each such Holder.

      the
      Notes, including by way of public announcement or through any of its agents,

      any other Transaction Document (as defined in the Securities Purchase Agreement)
      or any other agreement, document, certificate or other instrument delivered
      in
      connection with the transactions contemplated hereby and thereby to which the

      rendered against the Company or any of its Subsidiaries and which judgments
      are
      not, within sixty (60) days after the entry thereof, bonded, discharged or
      stayed pending appeal, or are not discharged within sixty (60) days after the
      expiration of such stay; provided , however ,
      that
      any judgment which is covered by insurance or an indemnity from a credit worthy
      party shall not be included in calculating the $2,000,000 **** amount
      set forth above so long as the Company provides the Holder a written statement
      from such insurer or indemnity provider (which written statement shall be
      reasonably satisfactory to the Holder) to the effect that such judgment is
      covered by insurance or an indemnity and the Company will receive the proceeds
      of such insurance or indemnity within thirty (30) days of the issuance of such
      judgment;




(vii)  other
      than as specifically set forth in another clause of this Section
      4(a) ,
      the
      Company materially breaches and fails to cure within any allowable cure period
      any representation, warranty, covenant or other term or condition of any
      Transaction Document, except, in the case of a breach of a covenant or other
      term or condition of any Transaction Document which is curable, only if such
      breach continues for a period of at least ten (10) consecutive Business
      Days;




(viii)  any
      breach or failure in any respect to comply with either of Sections
      8 or 14 of this
      Note; or




(ix)  any
      unwaived Event of Default (as defined in the Other Notes) occurs with respect
      to
      any Other Notes.




(b)  Redemption
      Right .
      Upon
      the occurrence of an Event of Default with respect to this Note or any Other
      Note, the Company shall within one (1) Business Day deliver written notice
      thereof via facsimile and overnight courier (an “ **Event
      of Default Notice** ”)
      to the
      Holder. At any time after the earlier of the Holder’s receipt of an Event of
      Default Notice and the Holder becoming aware of an Event of Default, the Holder
      may require the Company to redeem all or any portion of this Note by delivering
      written notice thereof (the “ **Event
      of Default Redemption Notice** ”)
      to the
      Company, which Event of Default Redemption Notice shall indicate the Conversion
      Amount of this Note the Holder is electing to require the Company to redeem.
      Each portion of this Note subject to redemption by the Company pursuant to
      this Section
      4(b) shall be
      redeemed by the Company at a price equal to the sum of (i) the Conversion Amount
      to be redeemed and (ii) the Other Make Whole Amount (the “ **Event
      of Default**  **Redemption
      Price** ”).
      Redemptions required by this Section
      4(b) shall be
      made in accordance with the provisions of Section
      12 .
      To the
      extent redemptions required by this Section
      4(b) are
      deemed or determined by a court of competent jurisdiction to be prepayments
      of
      the Note by the Company, such redemptions shall be deemed to be voluntary
      prepayments. The parties hereto agree that in the event of the Company’s
      redemption of any portion of the Note under this Section
      4(b) ,
      the
      Holder’s damages would be uncertain and difficult to estimate because of the
      parties’ inability to predict future interest rates and the uncertainty of the
      availability of a suitable substitute investment opportunity for the Holder.
      Accordingly, any premium due under this Section
      4(b) is
      intended by the parties to be, and shall be deemed, a reasonable estimate of
      the
      Holder’s actual loss of its investment opportunity and not as a
      penalty.

(5)  RIGHTS
      UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL .




(a)  Assumption .
      The
      Company shall not enter into or be party to a Fundamental Transaction unless
      the
      Successor Entity assumes in writing all of the obligations of the Company under
      this Note and the other Transaction Documents in accordance with the provisions
      of this Section
      5(a) pursuant
      to written agreements in form and substance reasonably satisfactory to the
      Required Holders prior to such Fundamental Transaction, including agreements
      to
      deliver to each Holder of Notes in exchange for such Notes a security of the
      Successor Entity evidenced by a written instrument substantially similar in
      form
      and substance to the Notes, including, without limitation, having a principal
      amount and interest rate equal to the principal amounts and the interest rates
      of the Notes then outstanding held by such Holder, having similar conversion
      rights and having similar ranking to the Notes. Upon the occurrence of any
      Fundamental Transaction, the Successor Entity shall succeed to, and be
      substituted for (so that from and after the date of such Fundamental
      Transaction, the provisions of this Note referring to the “Company” shall refer
      instead to the Successor Entity), and may exercise every right and power of
      the
      Company and shall assume all of the obligations of the Company under this Note
      with the same effect as if such Successor Entity had been named as the Company
      herein, except for (as described in the following sentence) the substitution
      of,
      instead of shares of Common Stock of the Company as initially provided herein,
      the delivery upon conversion of other applicable securities, cash, assets or
      other property. Upon consummation of the Fundamental Transaction, the Successor
      Entity shall deliver to the Holder confirmation that there shall be issued
      upon
      conversion or redemption of this Note (or exchange note issued under the first
      sentence of this paragraph) at
      any
      time after the consummation of the Fundamental Transaction, in lieu of the
      shares of the Company’s Common Stock (or
      other
      securities, cash, assets or other property) issuable
      upon the conversion or redemption of the Notes prior to such Fundamental
      Transaction , the same
      combination and amount of securities, cash, assets or other property as a holder
      of shares of Common Stock would have been entitled to receive in the Fundamental
      Transaction, in accordance with and as adjusted by the provisions of this Note. The
      provisions of this Section shall apply similarly and equally to successive
      Fundamental Transactions and shall be applied without regard to any limitations
      on the conversion or redemption of this Note.




(b)  Redemption
      Right .
      No
      sooner than fifteen (15) days prior to nor later than ten (10) days prior to
      the
      consummation of a Change of Control (the date of consummation, the “ **Change
      of Control Effective Date** ”),
      but
      not prior to the public announcement of such Change of Control, the Company
      shall deliver written notice thereof via facsimile and overnight courier to
      the
      Holder (a “ **Change
      of Control**  **Notice** ”).
      At
      any time and from time to time during the period beginning after the Holder’s
      receipt of a Change of Control Notice and ending on the Change of Control
      Effective Date (provided there has been at least ten (10) Trading Days between
      the date of the Change of Control Notice and the Change of Control Effective
      Date), the Holder may require the Company to redeem all or any portion of this
      Note by delivering written notice thereof (“ **Change
      of Control Redemption Notice** ”)
      to the
      Company, which Change of Control Redemption Notice shall indicate the Conversion
      Amount of the Holder is electing to require the Company to redeem. The
      portion of this Note subject to redemption pursuant to this Section
      5(b) shall be
      redeemed by the Company in cash at a price (the “ **Change
      of Control Redemption Price** ”)
      equal
      to the sum of (i) the Conversion Amount being redeemed and (ii) the Other Make
      Whole Amount .
      Notwithstanding anything to the contrary in this Section
      5(b) ,
      but
      subject to Section
      3(d) and Section
      5(a) ,
      until
      the Holder receives the Change of Control Redemption Price, the Change of
      Control Redemption Price may be converted, in whole or in part, as indicated
      by
      the Holder on a Change of Control Redemption Notice (the “ **Converted
      Portion** ”)
      pursuant to Section
      3(c) and Section
      5(a) hereof. Any
      c onversions
      required by this Section
      5(b) shall
      reduce the Change of Control Redemption Price and shall be made in accordance
      with the provisions of Section
      3(c )
      and Section
      5(a) .




11




(c)  General .
      Redemptions required by this Section
      5 shall be
      made in accordance with the provisions of Section
      12 and
      shall have priority to payments to stockholders in connection with a Change
      of
      Control. To the extent redemptions required by Section
      5(b) are
      deemed or determined by a court of competent jurisdiction to be prepayments
      of
      the Note by the Company, such redemptions shall be deemed to be voluntary
      prepayments. Notwithstanding anything to the contrary in this Section
      5 ,
      but
      subject to Section
      3(d) and Section
      5(a) ,
      until
      the Change of Control Redemption Price (together with any interest thereon)
      is
      paid in full, the Conversion Amount submitted for redemption under this Section
      5(c) (together with any interest thereon) may be converted, in whole or in part,
      by
      the Holder into Common Stock pursuant to Section
      3 and Section
      5(a) .
      The
      parties hereto agree that in the event of redemption of any portion of the
      Note
      under Section
      5(b) and
      because of the parties’ inability to predict future interest rates and the
      uncertainty of the availability of a suitable substitute investment opportunity
      for the Holder, any premium due under Section
      5(b) is
      intended by the parties to be, and shall be deemed, a reasonable estimate of
      the
      Holder’s actual loss of its investment opportunity and not as a
      penalty.




(d)  Make
      Whole Amounts .
      For
      purposes of this Note:




(i)  the
      “ **Maturity
      Make Whole Amount** ”
shall
      mean a premium to the Conversion Amount such that the total amount received
      by
      the Holder at Maturity represents a gross yield to the Holder on the Original
      Principal Amount as of the Maturity Date equal to thirteen percent (13%), with
      interest computed on the basis of actual number of days elapsed over a 360-day
      year.




(ii)  the
      “ **Other
      Make Whole Amount** ”
shall
      mean a premium to the Conversion Amount such that the total amount received
      by
      the Holder upon redemption represents a gross yield to the Holder on the
      Original Principal Amount as of the redemption date equal to thirteen percent
      (13%), with interest computed on the basis of actual number of days elapsed
      over
      a 360-day year.




12




(iii)  the
      “ **Annual
      Redemption Make Whole Amount** ”
shall
      mean a premium to the Conversion Amount such that the total amount received

      the Holder upon any Annual Redemption represents a gross yield on the Original
      Principal Amount of (A) ten percent (10%), if the redemption date occurs during
      2009, (B) eleven percent (11%), if the redemption date occurs during 2010 or
      2011, and (c) thirteen percent (13%), if the redemption date occurs during
      2012,
      in each case with interest computed on the basis of actual number of days
      elapsed over a 360-day year.




(iv)  The
      “ **Henglong
      Make Whole Amount** ”
shall
      mean a premium to the Conversion Amount such that the total amount received

      360-day year.




(6)  RIGHTS
      UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS .




(a)  Purchase
      Rights .
      If at
      any time the Company grants, issues or sells any Options, Convertible Securities
      or rights to purchase stock, warrants, securities or other property pro rata
      to
      the record holders of any class of Common Stock (the “ **Purchase
      Rights** ”),
      then
      the Holder will be entitled to acquire, upon the terms applicable to such
      Purchase Rights, the aggregate Purchase Rights which the Holder could have
      acquired if the Holder had held the number of shares of Common Stock acquirable
      upon complete conversion of this Note (without taking into account any
      limitations or restrictions on the convertibility of this Note) 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.




(b)  Other
      Corporate Events .
      In
      addition to and not in substitution for any other rights hereunder, prior to
      the
      consummation of any Fundamental Transaction pursuant to which holders of shares
      of Common Stock are entitled to receive securities or other assets with respect
      to or in exchange for shares of Common Stock (a “ **Corporate
      Event** ”),
      the
      Company shall make appropriate provision to insure that the Holder will
      thereafter have the right to receive upon a conversion of this Note, at the
      Holder’s option, (i) in addition to the shares of Common Stock receivable upon
      such conversion, such securities or other assets to which the Holder would
      have
      been entitled with respect to such shares of Common Stock had such shares of
      Common Stock been held by the Holder upon the consummation of such Corporate
      Event (without taking into account any limitations or restrictions on the
      convertibility of this Note) or (ii) in lieu of the shares of Common Stock
      otherwise receivable upon such conversion, such securities or other assets
      received by the holders of shares of Common Stock in connection with the
      consummation of such Corporate Event in such amounts as the Holder would have
      been entitled to receive had this Note initially been issued with conversion
      rights for the form of such consideration (as opposed to shares of Common Stock)
      at a conversion rate for such consideration commensurate with the Conversion
      Rate. Provision made pursuant to the preceding sentence shall be in a form
      and
      substance reasonably satisfactory to the Required Holders. The provisions of
      this Section shall apply similarly and equally to successive Corporate Events
      and shall be applied without regard to any limitations on the conversion or
      redemption of this Note.

(7)  RIGHTS
      UPON ISSUANCE OF OTHER SECURITIES .




(a)  Adjustment
      of Conversion Price upon Issuance of Common Stock .
      If and
      whenever on or after the Issuance Date, the Company issues or sells, or in
      accordance with this Section
      7(a) is
      deemed to have issued or sold, any shares
      of Common
      Stock (including the issuance or sale of shares
      of Common
      Stock owned or held by or for the account of the Company, but excluding shares
      of Common
      Stock deemed to have been issued or sold by the Company in connection with
      any
      Excluded Security) for a consideration per share less than a price (the
“ **Applicable
      Price** ”)
      equal
      to the Conversion Price in effect immediately prior to such issue or sale (the
      foregoing a “ **Dilutive
      Issuance** ”),
      then
      immediately after such Dilutive Issuance the Conversion Price then in effect
      shall be an amount equal to the
      following:




NCP
            =
            APx[(OCP
                x OS) + (C)] [       (AP x
              NS)]




where:




NCP
            =
            new
                Conversion Price (immediately after such Dilutive
                Issuance)


OCP
            =
            old
                Conversion Price (immediately prior to such Dilutive
                Issuance)


AP
            =
            the
                Applicable Price


NS
            =
            new
                shares of Common Stock Deemed Outstanding (immediately after such
                Dilutive
                Issuance)


OS
            =
            old
                shares of Common Stock Deemed Outstanding (immediately prior to such
                Dilutive Issuance)


C
            =
            the
                consideration, if any, received by the Company upon such Dilutive
                Issuance





For
      purposes of determining the adjusted Conversion Price under this Section
      7(a) ,
      the
      following shall be applicable:




(i)  Issuance
      of Options .
      If the
      Company in any manner grants or sells any Options and the lowest price per
      share
      for which one share
      of Common
      Stock is issuable upon the exercise of any such Option or upon conversion or
      exchange or exercise of any Convertible Securities issuable upon exercise of
      such Option is less than the Applicable Price, then such share
      of Common
      Stock shall be deemed to be outstanding and to have been issued and sold by
      the
      Company at the time of the granting or sale of such Option for such price per
      share. For purposes of this Section
      7(a)(i) ,
      the
“lowest price per share for which one share
      of Common
      Stock is issuable upon the exercise of any such Option or upon conversion or
      exchange or exercise of any Convertible Securities issuable upon exercise of
      such Option” shall be equal to the sum of the lowest amounts of consideration
      (if any) received or receivable by the Company with respect to any one share
      of Common
      Stock upon granting or sale of the Option, upon exercise of the Option and
      upon
      conversion or exchange or exercise of any Convertible Security issuable upon
      exercise of such Option. No further adjustment of the Conversion Price shall
      be
      made upon the actual issuance of such share of Common Stock or of such
      Convertible Securities upon the exercise of such Options or upon the actual
      issuance of such Common Stock upon conversion or exchange or exercise of such
      Convertible Securities.




14




(ii)  Issuance
      of Convertible Securities .
      If the
      Company in any manner issues or sells any Convertible Securities and the lowest
      price per share for which one share of Common Stock is issuable upon such
      conversion or exchange or exercise thereof is less than the Applicable Price,
      then such share of Common Stock shall be deemed to be outstanding and to have
      been issued and sold by the Company at the time of the issuance or sale of
      such
      Convertible Securities for such price per share. For the purposes of this Section
      7(a)(ii) ,
      the
“lowest price per share for which one share of Common Stock is issuable upon
      such conversion or exchange or exercise” shall be equal to the sum of the lowest
      amounts of consideration (if any) received or receivable by the Company with
      respect to any one share of Common Stock upon the issuance or sale of the
      Convertible Security and upon the conversion or exchange or exercise of such
      Convertible Security. No further adjustment of the Conversion Price shall be
      made upon the actual issuance of such share of Common Stock upon conversion
      or
      exchange or exercise of such Convertible Securities, and if any such issue
      or
      sale of such Convertible Securities is made upon exercise of any Options for
      which adjustment of the Conversion Price had been or are to be made pursuant
      to
      other provisions of this Section
      7(a) ,
      no
      further adjustment of the Conversion Price shall be made by reason of such
      issue
      or sale.




(iii)  Change
      in Option Price or Rate of Conversion .
      If the
      purchase price provided for in any Options, the additional consideration, if
      any, payable upon the issue, conversion, exchange or exercise of any Convertible
      Securities, or the rate at which any Convertible Securities are convertible
      into
      or exchangeable or exercisable for Common Stock changes at any time, the
      Conversion Price in effect at the time of such change shall be adjusted to
      the
      Conversion Price which would have been in effect at such time had such Options
      or Convertible Securities provided for such changed purchase price, additional
      consideration or changed conversion rate, as the case may be, at the time
      initially granted, issued or sold. For purposes of this Section
      7(a)(iii) ,
      if the
      terms of any Option or Convertible Security that was outstanding as of the
      Issuance Date are changed in the manner described in the immediately preceding
      sentence, then such Option or Convertible Security and the Common Stock deemed
      issuable upon exercise, conversion or exchange thereof shall be deemed to have
      been issued as of the date of such change. No adjustment shall be made if such
      adjustment would result in an increase of the Conversion Price then in
      effect.




(iv)  Calculation
      of Consideration Received .
      In case
      any Option is issued in connection with the issue or sale of other securities
      of
      the Company, together comprising one integrated transaction in which no specific
      consideration is allocated to such Options by the parties thereto, (x) the
      Options will be deemed to have been issued for a value determined by use of
      the
      Black Scholes Option Pricing Model (the “ **Option
      Value** ”)
      and
      (y) the other securities issued or sold in such integrated transaction shall
      be
      deemed to have been issued for the difference of (I) the aggregate consideration
      received by the Company, less (II) the Option Value. If any Common Stock,
      Options or Convertible Securities are issued or sold or deemed to have been
      issued or sold for cash, the consideration received therefor will be deemed
      to
      be the net amount received by the Company therefor. If any Common Stock, Options
      or Convertible Securities are issued or sold for a consideration other than
      cash, the amount of the consideration other than cash received by the Company
      will be the fair value of such consideration, except where such consideration
      consists of securities, in which case the amount of consideration received
      by
      the Company will be the Closing Sale Price of such securities on the date of
      receipt. If any Common Stock, Options or Convertible Securities are issued
      to
      the owners of the non-surviving entity in connection with any merger in which
      the Company is the surviving entity, the amount of consideration therefor will
      be deemed to be the fair value of such portion of the net assets and business
      of
      the non-surviving entity as is attributable to such Common Stock, Options or
      Convertible Securities, as the case may be. The fair value of any consideration
      other than cash or securities will be determined jointly by the Company and
      the
      Required Holders. If such parties are unable to reach agreement within ten
      (10)
      days after the occurrence of an event requiring valuation (the “ **Valuation
      Event** ”),
      the
      fair value of such consideration will be determined within five (5) Business
      Days after the tenth (10 th )
      day
      following the Valuation Event by an independent, reputable appraiser jointly
      selected by the Company and the Required Holders. The determination of such
      appraiser shall be deemed binding upon all parties absent manifest error and
      the
      fees and expenses of such appraiser shall be borne by the Company.




15




(v)  Record
      Date .
      If the
      Company takes a record of the holders of Common Stock for the purpose of
      entitling them (A) to receive a dividend or other distribution payable in Common
      Stock, Options or in Convertible Securities or (B) to subscribe for or purchase
      Common Stock, Options or Convertible Securities, then such record date will
      be
      deemed to be the date of the issue or sale of the Common Stock deemed to have
      been issued or sold upon the declaration of such dividend or the making of
      such
      other distribution or the date of the granting of such right of subscription
      or
      purchase, as the case may be.




(b)  Adjustment
      of Conversion Price upon Subdivision or Combination of Common
      Stock .
      If the
      Company at any time on or after the Issuance Date subdivides (by any stock
      dividend, stock split, recapitalization or otherwise) one or more classes of
      its
      outstanding shares of Common Stock into a greater number of shares, the
      Conversion Price in effect immediately prior to such subdivision will be
      proportionately reduced. If the Company at any time on or after the Issuance
      Date combines (by combination, reverse stock split or otherwise) one or more
      classes of its outstanding shares of Common Stock into a smaller number of
      shares, the Conversion Price in effect immediately prior to such combination
      will be proportionately increased.




(c)  Other
      Events .
      If any
      event occurs of the type contemplated by the provisions of this Section
      7 but not
      expressly provided for by such provisions (including, without limitation, the
      granting of stock appreciation rights, phantom stock rights or other rights
      with
      equity features), then the Company’s Board of Directors will make an appropriate
      adjustment in the Conversion Price so as to protect the rights of the Holder
      under this Note; provided that no
      such adjustment will increase the Conversion Price as otherwise determined
      pursuant to this Section
      7 .




16




(d)  Voluntary
      Decrease .
      The
      Company may at any time during the term of this Note reduce the then current
      Conversion Price to any amount and for any period of time deemed appropriate
      by
      the Board of Directors.




(e)  Excluded
      Securities .
      The
      issuance of any Excluded Securities shall not result in an adjustment to the
      Conversion Price.




(8)  HOLDER’S
      RIGHT OF MANDATORY REDEMPTION . ****




(a)  General .




(i)  On
      each
      of February 15, 2010 and February 15, 2011 (the “ **Annual
      Redemption** ”),
      the
      Holder shall have the right (the “ **Annual
      Redemption Right** ”),
      in
      its sole discretion, to require that the Company redeem the Note in whole but
      not in part, by delivering written notice thereof to the Company (an
“ **Annual
      Redemption Notice** ”).




(ii)  In
      the
      event (each of the events set forth in (x) and (y) a “ **Listing
      Default** ”)
      (x)
      the Company has not filed to list the Conversion Shares on its Principal Market
      by the date that is ninety (90) days after the Issuance Date or has not so
      listed the Conversion Shares by the date that is ninety (90) days after the
      Issuance Date (as required pursuant to Section
      3(a) of the
      Registration Rights Agreement); or (y) the shares of the Company’s Common Stock
      are (A) subject to any Grace Periods ((as defined in the Registration Rights
      Agreement), terminated from registration under the Securities Act of 1933,
      as
      amended (the “ **Act** ”),
      during the time in which the Company remains obligated under Section
      2(f) of the
      Registration Rights Agreement to keep the R egistration
      Statement current, effective and free from any material misstatement or omission
      to state a material fact or (B) are delisted from the Principal Market for
      more
      than ten (10) Trading Days, the Holder shall have the right (the “ **Listing
      Default Redemption Right** ”),
      in
      its sole discretion, to require that the Company redeem all or any portion
      of
      the Note by delivering written notice thereof to the Company (a “ **Listing
      Default Mandatory Redemption Notice** ”).




(iii)  At
      anytime following the first anniversary of the Issuance Date, if the Weighted
      Average for twenty (20) consecutive Trading Days is less than forty-five percent
      (45%) of the Conversion Price in effect on the Issuance Date, as adjusted (a
      “ **WAP
      Default** ”),
      the
      Holder shall have the right (a “ **WAP
      Default Redemption Right,** ”
and
      together with the Listing Default Redemption Right, the Annual Redemption Right
      and the Henglong Default Redemption Right (as defined below) a “ **Holder
      Redemption Right** ”),
      in
      its sole discretion, to require that the Company redeem all or any portion
      of
      the Note by delivering written notice thereof to the Company within five (5)
      Business Days after the Company notice described in paragraph (v) below or
      if no
      such Company Notice is received, at any time after a WAP Default upon written
      notice to the Company (a “ **Holder
      WAP Redemption Notice** ”
and
      together with the Listing Default Redemption Notice, the Annual Redemption
      Notice, and the Henglong Default Redemption Notice (as defined below) a
“ **Holder
      Redemption Notice** ”).




17




(iv)  Henglong
      Redemption Right .
      In the
      event the Company has not consummated the Henglong Transaction by April 15,
      2008
      on terms and conditions satisfactory to the Lead Investor as required by the
      Securities Purchase Agreement (a “ **Henglong
      Default** ”),
      the
      Holder shall have the right (the “ **Henglong
      Default Redemption Right** ”),
      in
      its sole discretion, to require that the Company redeem all but not less than
      all of the Note within thirty (30) days following the first anniversary of
      the
      Issuance Date by delivering written notice thereof to the Company (a
“ **Henglong
      Default Redemption Notice** ”)
      at
      anytime prior to the first anniversary of the Issuance Date. If the Henglong
      Transaction is consummated on or prior to April 15, 2008 on terms and conditions
      satisfactory to the Lead Investor, or if the Escrow Amount (as defined in the
      Securities Purchase Agreement) is released to the Company on or prior to April
      30, 2008, whichever occurs earlier, the Holder’s Henglong Default Redemption
      Right shall immediately expire.




(v)  The
      Company shall deliver written notice (the “ **Company
      Notice** ”)
      to the
      Holder no later than two (2) Business Days following a Listing Default, a WAP
      Default or a Henglong Default stating (x) the Mandatory Redemption Price (as
      defined below) and (y) that the Holder’s right of redemption under this Section
      8(a)(ii) , (iii )
      or (iv) is
      effective and the period during which the redemption may be exercised.




(b)  In
      order
      to exercise the Holder Redemption Right, the Holder Redemption Notice shall
      indicate the Conversion Amount the Holder is electing to have redeemed (the
      “ **Redemption
      Amount** ”),
      which
      shall be the entire Conversion Amount in the case of the Annual Redemption
      Right
      or the Henglong Default Redemption Right, on the redemption date set forth
      on
      the Holder Redemption Notice (the “ **Holder
      Mandatory Redemption Date** ”),
      which
      date shall be no earlier than five (5) Business
      Days after the date the Holder has delivered the Holder Redemption Notice to
      the
      Company in the case of a Listing Default Redemption Right, thirty (30) days
      after such delivery in the case of a Henglong Default Redemption Right or ninety
      (90) days after such delivery in the case of a WAP Default Redemption Right
      and
      an Annual Redemption Right .
      The
      portion of this Note subject to redemption pursuant to the Holder Redemption
      Right shall be redeemed by the Company in cash at a price equal to the sum
      of
      (i) the Conversion Amount being redeemed and (ii) in the case of an Annual
      Redemption Right, the Annual Redemption Make Whole Amount, in the case of a
      Henglong Default Redemption Right, the Henglong Make Whole Amount or in the case
      of the WAP Default Redemption Right or the Listing Default Redemption Right,
      the
      Other Make Whole Amount **** (the
      “ **Mandatory
      Redemption Price** ”).  Notwithstanding
      anything to the contrary in this Section
      8 ,
      but
      subject to Section
      3(d) ,
      beginning on the Holder Mandatory Redemption Date and until the Holder receives
      the Mandatory Redemption Price, the Mandatory Redemption Amount may be
      converted, in whole or in part, as indicated by the Holder on a Holder
      Redemption Notice (the “ **Converted
      Amount** ”)
      into a
      number of shares of Common Stock determined by dividing the Converted Amount
      by
      the lesser of (i) the Conversion Price and (ii) the greater of (A) the
      arithmetic average of the ten (10) Trading Days immediately preceding the
      Conversion Date and (B) $3.5411 and provided that, if
      required by the Principal Market, stockholder approval has been obtained. Any
      such conversion shall reduce the Mandatory Redemption Amount.




(c)  Mechanics
      of Holder Mandatory Redemption .
      If the
      Holder elects a Holder Mandatory Redemption in accordance with Section
      8(a) ,
      then
      the Mandatory Redemption Amount which is to be paid to the Holder on the
      applicable Mandatory Redemption Date shall be redeemed by the Company, and
      the
      Company shall pay to the Holder on such Mandatory Redemption Date by wire
      transfer of immediately available funds, the applicable Mandatory Redemption
      Price.




18




(9)  COMPANY’S
      RIGHT OF OPTIONAL REDEMPTION .




(a)  General .
      At any
      time that less than ten percent (10%) of the Original Principal Amount of all
      Notes remains outstanding, the Company shall have the right to redeem all or
      any
      portion of the Conversion Amount under this Note (the “ **Optional
      Redemption Amount** ”)
      as
      designated in the Optional Redemption Notice on the Optional Redemption Date
      (each as defined below) (an “ **Optional
      Redemption** ”).
      The
      portion of this Note subject to redemption pursuant to this Section
      9(a) shall be
      redeemed by the Company in cash at a price (the “ **Optional
      Redemption Price** ”)
      equal
      to the sum of (i) the Conversion Amount being redeemed and (ii) the Other Make
      Whole Amount. The Company may exercise its right to require redemption under
      this Section
      9 by
      delivering a written notice thereof by facsimile and overnight courier to all,
      but not less than all, of the holders of Notes (the “ **Optional
      Redemption Notice** ”
and
      the
      date all of the holders received such notice is referred to as the “ **Optional
      Redemption Notice Date** ”).
      Each
      Optional Redemption Notice shall be irrevocable. The Optional Redemption Notice
      shall state (1) the date on which the Optional Redemption shall occur (the
      “ **Optional
      Redemption Date** ”)
      which
      date shall not be less than five (5) nor more than fifteen (15) Business Days
      following the Optional Redemption Notice Date and (2) the aggregate Conversion
      Amount of the Notes which the Company has elected to be subject to Optional
      Redemption from the Holder and all of the other holders of the Notes pursuant
      to
      this Section
      9(a) (and
      analogous provisions under the Other Notes) on the Optional Redemption Date.
      The
      Company may not effect more than one (1) Optional Redemption. Notwithstanding
      anything to the contrary in this Section
      9 ,
      until
      the Optional Redemption Price is paid, in full, the Optional Redemption Amount
      may be converted, in whole or in part, by the Holders into shares of Common
      Stock pursuant to Section
      3 .
      All
      Conversion Amounts converted by the Holder after the Optional Redemption Notice
      Date shall reduce the Optional Redemption Amount of this Note required to be
      redeemed on the Optional Redemption Date. Redemptions made pursuant to this Section
      9 shall be
      made in accordance with Section
      12 .




(b)  Pro
      Rata Redemption Requirement .
      If the
      Company elects to cause an Optional Redemption pursuant to Section
      9(a) ,
      then it
      must simultaneously take the same action in the same proportion with respect
      to
      the Other Notes. If the Company elects to cause an Optional Redemption pursuant
      to Section
      9(a) (or
      similar provisions under the Other Notes) with respect to less than all of
      the
      Conversion Amounts of the Notes then outstanding, then the Company shall require
      redemption of a Conversion Amount from each of the holders of the Notes equal
      to
      the product of (i) the aggregate Conversion Amount of Notes which the Company
      has elected to cause to be redeemed pursuant to Section
      9(a) ,
      multiplied by (ii) the fraction, the numerator of which is the sum of the
      aggregate Original Principal Amount of the Notes purchased by such holder of
      outstanding Notes and the denominator of which is the sum of the aggregate
      Original Principal Amount of the Notes purchased by all holders holding
      outstanding Notes (such fraction with respect to each holder is referred to
      as
      its “ **Redemption
      Allocation Percentage** ”,
      and
      such amount with respect to each holder is referred to as its “ **Pro
      Rata Redemption Amount** ”); provided , however that in
      the event that any holder’s Pro Rata Redemption Amount exceeds the outstanding
      Principal amount of such holder’s Note, then such excess Pro Rata Redemption
      Amount shall be allocated amongst the remaining holders of Notes in accordance
      with the foregoing formula. In the event that the initial holder of any Notes
      shall sell or otherwise transfer any of such holder’s Notes, the transferee
      shall be allocated a pro rata portion of such holder’s Redemption Allocation
      Percentage and Pro Rata Redemption Amount.

(10)  NONCIRCUMVENTION .
      The
      Company hereby covenants and agrees that the Company will not, by amendment
      of
      its Certificate of Incorporation, Bylaws or through any reorganization, transfer
      of assets, consolidation, merger, scheme of arrangement, dissolution, issue
      or
      sale of securities, or any other voluntary action, avoid or seek to avoid the
      observance or performance of any of the terms of this Note, and will at all
      times in good faith carry out all of the provisions of this Note and take all
      action as may be required to protect the rights of the Holder of this Note.




(11)  RESERVATION
      OF AUTHORIZED SHARES .




(a)  Reservation .
      The
      Company shall reserve out of its authorized and unissued Common Stock a number
      of shares of Common Stock for each of the Notes equal to 120% of the Conversion
      Rate with respect to the Conversion Amount of each such Note as of the
      Issuance **** Date.
      So
      long as any of the Notes are outstanding, the Company shall take all action
      necessary to reserve and keep available out of its authorized and unissued
      Common Stock, solely for the purpose of effecting the conversion of the Notes,
      120% of the number of shares of Common Stock as shall from time to time be
      necessary to effect the conversion of all of the Notes then outstanding; provided that at
      no time shall the number of shares of Common Stock so reserved be less than
      the
      number of shares required to be reserved by the previous sentence (without
      regard to any limitations on conversions) (the “ **Required
      Reserve Amount** ”).
      The
      initial number of shares of Common Stock reserved for conversions of the Notes
      and each increase in the number of shares so reserved shall be allocated pro
      rata among the holders of the Notes based on the principal amount of the Notes
      held by each holder at the Closing (as defined in the Securities Purchase
      Agreement) or increase in the number of reserved shares, as the case may be
      (the
“ **Authorized
      Share Allocation** ”).
      In
      the event that a holder shall sell or otherwise transfer any of such holder’s
      Notes, each transferee shall be allocated a pro rata portion of such holder’s
      Authorized Share Allocation. Any shares of Common Stock reserved and allocated
      to any Person which ceases to hold any Notes shall be allocated to the remaining
      holders of Notes, pro rata based on the principal amount of the Notes then
      held
      by such holders.




(b)  Insufficient
      Authorized Shares .
      If at
      any time while any of the Notes remain outstanding the Company does not have
      a
      sufficient number of authorized and unreserved shares of Common Stock to satisfy
      its obligation to reserve for issuance upon conversion of the Notes at least
      a
      number of shares of Common Stock equal to the Required Reserve Amount (an
“ **Authorized
      Share Failure** ”),
      then
      the Company shall take all action necessary to increase the Company’s authorized
      shares of Common Stock to an amount sufficient to allow the Company to reserve
      the Required Reserve Amount for the Notes then outstanding. Without limiting
      the
      generality of the foregoing sentence, as soon as practicable after the date
      of
      the occurrence of an Authorized Share Failure, but in no event later than sixty
      (60) days after the occurrence of such Authorized Share Failure, the Company
      shall hold a meeting of its stockholders for the approval of an increase in
      the
      number of authorized shares of Common Stock. In connection with such meeting,
      the Company shall provide each stockholder with a proxy statement and shall
      use
      its best efforts to solicit its stockholders’ approval of such increase in
      authorized shares of Common Stock and to cause its board of directors to
      recommend to the stockholders that they approve such proposal.

(12)  REDEMPTIONS .




(a)  Mechanics .
      The
      Company shall deliver the applicable Event of Default Redemption Price to the
      Holder within five (5) Business Days after the Company’s receipt of the Holder’s
      Event of Default Redemption Notice. If the Holder has submitted a Change of
      Control Redemption Notice in accordance with Section
      5(b) ,
      the
      Company shall deliver the applicable Change of Control Redemption Price to
      the
      Holder concurrently with the consummation of such Change of Control. The Company
      shall deliver the applicable Mandatory Redemption Price on the Holder Mandatory
      Redemption Date. The Company shall deliver the applicable Optional Redemption
      Price on the applicable Optional Redemption Date. In the event of a redemption
      of less than all of the Conversion Amount of this Note, the Company shall
      promptly cause to be issued and delivered to the Holder, against surrender
      of
      the original Note, a new Note (in accordance with Section
      18(d) )
      representing the outstanding Principal which has not been redeemed. In the
      event
      that the Company does not pay the applicable Redemption Price to the Holder
      within the time period required, at any time thereafter and until the Company
      pays such unpaid Redemption Price in full, the Holder shall have the option,
      in
      lieu of redemption, to require the Company to promptly return to the Holder
      all
      or any portion of this Note representing the Conversion Amount that was
      submitted for redemption and for which the applicable Redemption Price (together
      with any Late Charges thereon) has not been paid. Subject to any different
      conversion price provided for in Section
      8(b) ,
      and
      subject to prior stockholder approval if required by the Principal Market,
      upon
      the Company’s receipt of such notice, (x) the applicable Redemption Notice shall
      be null and void with respect to such Conversion Amount, (y) the Company shall
      immediately return this Note, or issue a new Note (in accordance with Section
      18(d) )
      to the
      Holder representing such Conversion Amount that was to be redeemed and (z)
      the
      Conversion Price of this Note or such new Notes shall be adjusted to the lesser
      of (A) the Conversion Price as in effect on the date on which the applicable
      Redemption Notice is voided and (B) the lowest Closing Bid Price of the Common
      Stock during the period beginning on and including the date on which the
      applicable Redemption Notice is delivered to the Company and ending on and
      including the date on which the applicable Redemption Notice is voided but
      in no
      event lower than $3.5411. The Holder’s delivery of a notice voiding a Redemption
      Notice and exercise of its rights following such notice shall not affect the
      Company’s obligations to make any payments of Late Charges which have accrued
      prior to the date of such notice with respect to the Conversion Amount subject
      to such notice.




(b)  Redemption
      by Other Holders .
      Upon
      the Company’s receipt of notice from any of the holders of the Other Notes for
      redemption or repayment as a result of an event or occurrence substantially
      similar to the events or occurrences described in Section
      4(b) , Section
      5(b) or Section
      8 (each,
      an “ **Other
      Redemption Notice** ”),
      the
      Company shall immediately, but no later than one (1) Business Day of its receipt
      thereof, forward to the Holder by facsimile a copy of such notice. If the
      Company receives a Redemption Notice and one or more Other Redemption Notices,
      during the seven (7) Business Day period beginning on and including the date
      which is three (3) Business Days prior to the Company’s receipt of the Holder’s
      Redemption Notice and ending on and including the date which is three (3)
      Business Days after the Company’s receipt of the Holder’s Redemption Notice and
      the Company is unable to redeem all principal, interest and other amounts
      designated in such Redemption Notice and such Other Redemption Notices received
      during such seven (7) Business Day period, then the Company shall redeem a
      pro
      rata amount from each holder of the Notes (including the Holder) based on the
      principal amount of the Notes submitted for redemption pursuant to such
      Redemption Notice and such Other Redemption Notices received by the Company
      during such seven Business Day period.

(d)  Issuance
      of New Notes .
      Whenever the Company is required to issue a new Note pursuant to the terms
      of
      this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall

      CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE
      RELIEF .
      The
      remedies provided in this Note shall be cumulative and in addition to all other
      remedies available under this Note and any of the other Transaction Documents
      at
      law or in equity (including a decree of specific performance and/or other
      injunctive relief), and nothing herein shall limit the Holder’s right to pursue
      actual and consequential damages for any failure by the Company to comply with
      the terms of this Note. Amounts set forth or provided for herein with respect
      to
      payments, conversion and the like (and the computation thereof) shall be the
      amounts to be received by the Holder and shall not, except as expressly provided
      herein, be subject to any other obligation of the Company (or the performance
      thereof). The Company acknowledges that a breach by it of its obligations
      hereunder will cause irreparable harm to the Holder and that the remedy at
      law
      for any such breach may be inadequate. The Company therefore agrees that, in
      the
      event of any such breach or threatened breach, the Holder shall be entitled,
      in
      addition to all other available remedies, to an injunction restraining any
      breach, without the necessity of showing economic loss and without any bond

      of this Note or (b) there occurs any bankruptcy, reorganization, receivership

      herein, and hereby irrevocably waives, and agrees not to assert in any suit,
      action or proceeding, any claim that it is not personally subject to the
      jurisdiction of any such court, that such suit, action or proceeding is brought
      in an inconvenient forum or that the venue of such suit, action or proceeding
      is
      improper. Nothing contained herein shall be deemed to limit in any way any
      right
      to serve process in any manner permitted by law. The Holder and the Company

      obligations, or to enforce a judgment or other court ruling in favor of the

(28)  SEVERABILITY .
      If any
      provision of this Note is prohibited by law or otherwise determined to be
      invalid or unenforceable by a court of competent jurisdiction, the provision
      that would otherwise be prohibited, invalid or unenforceable shall be deemed
      amended to apply to the broadest extent that it would be valid and enforceable,
      and the invalidity or unenforceability of such provision shall not affect the
      validity of the remaining provisions of this Note so long as this Note as so
      modified continues to express, without material change, the original intentions
      of the parties as to the subject matter hereof and the prohibited nature,
      invalidity or unenforceability of the provision(s) in question does not
      substantially impair the respective expectations or reciprocal obligations
      of
      the parties or the practical realization of the benefits that would otherwise
      be
      conferred upon the parties. The parties will endeavor in good faith negotiations
      to replace the prohibited, invalid or unenforceable provision(s) with a valid
      provision(s), the effect of which comes as close as possible to that of the
      prohibited, invalid or unenforceable provision(s).
