      pay cash dividends as of the Closing Date. If at any time the Corporation has
      the right to pay dividends in cash or Common Stock, the Corporation must provide
      the Holders with at least ten Trading Days’ notice of its election to pay a
      regularly scheduled dividend in Common Stock (the Corporation may indicate
      in
      such notice that the election contained in such notice shall continue for later
      periods until revised by a subsequent notice). Dividends on the Preferred Stock
      shall be calculated on the basis of a 360-day year, consisting of twelve 30
      calendar day periods, shall accrue daily commencing on the Original Issue Date,
      and shall be deemed to accrue from such date whether or not earned or declared
      and whether or not there are profits, surplus or other funds of the Corporation
      legally available for the payment of dividends. Except as otherwise provided
      herein, if at any time the Corporation pays dividends partially in cash and
      partially in shares, then such payment shall be distributed ratably among the
      Holders based upon the number of shares of Preferred Stock held by each Holder
      on such Dividend Payment Date. Any dividends, whether paid in cash or shares
      of
      Common Stock, that are not paid within three Trading Days following a Dividend
      Payment Date shall continue to accrue and shall entail a late fee, which must
      be
      paid in cash, at the rate of 18% per annum or the lesser rate permitted by
      applicable law (such fees to accrue daily, from the Dividend Payment Date
      through and including the date of payment). If at any time the Corporation
      delivers a notice to the Holders of its election to pay the dividends in shares
      of Common Stock, the Corporation shall timely file a prospectus supplement
      pursuant to Rule 424 disclosing such election.

     

    b)  So
      long
      as any Preferred Stock shall remain outstanding, neither the Corporation nor
      any
      Subsidiary thereof shall redeem, purchase or otherwise acquire directly or
      indirectly any Junior Securities except as expressly permitted by Section
      9(a)(viii). So long as any Preferred Stock shall remain outstanding, neither
      the
      Corporation nor any Subsidiary thereof shall directly or indirectly pay or
      declare any dividend or make any distribution upon (other than a dividend or
      distribution described in Section 7 or dividends due and paid in the ordinary
      course on preferred stock of the Corporation at such times when the Corporation
      is in compliance with its payment and other obligations hereunder), nor shall
      any distribution be made in respect of, any Junior Securities as long as any
      dividends due on the Preferred Stock remain unpaid, nor shall any monies be
      set
      aside for or applied to the purchase or redemption (through a sinking fund
      or
      otherwise) of any Junior Securities or shares pari passu
      with the
      Preferred Stock.

    


    c)  The
      Corporation acknowledges and agrees that the capital of the Corporation in
      respect of the Preferred Stock and any future issuances of the Corporation’s
      capital stock shall be equal to the aggregate par value of such Preferred Stock
      or capital stock, as the case may be, and that, on or after the date of the
      Purchase Agreement, it shall not increase the capital of the Corporation with
      respect to any shares of the Corporation’s capital stock issued and outstanding
      on such date. The Corporation also acknowledges and agrees that it shall not
      create any special reserves without the prior written consent of each
      Holder.

    Section
      4.
       Voting
      Rights.
      Except
      as otherwise provided herein or as otherwise required by law, the Preferred
      Stock shall have no voting rights. However, as long as any shares of Preferred
      Stock are outstanding, the Corporation shall not, without the affirmative vote
      of the Holders of a majority of the then outstanding shares of the Preferred
      Stock, (a) alter or change adversely the powers, preferences or rights given
      to
      the Preferred Stock or alter or amend this Certificate of Designation, (b)
      authorize or create any class of stock ranking as to dividends, redemption
      or
      distribution of assets upon a Liquidation (as defined in Section 5) senior
      to or
      otherwise pari passu
      with the
      Preferred Stock, (c) amend its certificate of incorporation or other charter
      documents in any manner that adversely affects any rights of the Holders, (d)
      increase the authorized number of shares of Preferred Stock, or (e) enter into
      any agreement with respect to any of the foregoing.

     

    Section
      5.
       Liquidation.
      Upon
      any liquidation, dissolution or winding-up of the Corporation, whether voluntary
      or involuntary (a “Liquidation”),
      the
      Holders shall be entitled to receive out of the assets, whether capital or
      surplus, of the Corporation an amount equal to the Stated Value, plus any
      accrued and unpaid dividends thereon and any other fees or liquidated damages
      owing thereon, for each share of Preferred Stock before any distribution or
      payment shall be made to the holders of any Junior Securities, and if the assets
      of the Corporation shall be insufficient to pay in full such amounts, then
      the
      entire assets to be distributed to the Holders shall be ratably distributed
      among the Holders in accordance with the respective amounts that would be
      payable on such shares if all amounts payable thereon were paid in full. A
      Fundamental Transaction or Change of Control Transaction shall not be deemed
      a
      Liquidation. The Corporation shall mail written notice of any such Liquidation,
      not less than 45 days prior to the payment date stated therein, to each
      Holder.

    


    Section
      6.
       Conversion.

    


    a)  Conversions
      at Option of Holder.
      Each
      share of Preferred Stock shall be convertible at the option of the Holder
      thereof, at any time and from time to time from and after the Original Issue
      Date into that number of shares of Common Stock (subject to the limitations
      set
      forth in Section 6(c) )determined by dividing the Stated Value of such share
      of
      Preferred Stock by the Conversion Price. Holders shall effect conversions by
      providing the Corporation with the form of conversion notice attached hereto
      as
Annex
      A
      (a
“Notice
      of Conversion”).
      Each
      Notice of Conversion shall specify the number of shares of Preferred Stock
      to be
      converted, the number of shares of Preferred Stock owned prior to the conversion
      at issue, the number of shares of Preferred Stock owned subsequent to the
      conversion at issue and the date on which such conversion is to be effected,
      which date may not be prior to the date the applicable Holder delivers by
      facsimile such Notice of Conversion to the Corporation (such date, the
“Conversion
      Date”).
      If no
      Conversion Date is specified in a Notice of Conversion, the Conversion Date
      shall be the date that such Notice of Conversion to the Corporation is deemed
      delivered hereunder. The calculations and entries set forth in the Notice of
      Conversion shall control in the absence of manifest or mathematical error.
      To
      effect conversions of shares of Preferred Stock, a Holder shall not be required
      to surrender the certificate(s) 

     

    
      
        
        

      

      
        9

        
          

        

      

      
        
        

      

    

    representing
      such shares of Preferred Stock to the Corporation unless all of the shares
      of
      Preferred Stock represented thereby are so converted, in which case such Holder
      shall deliver the certificate representing such shares of Preferred Stock
      promptly following the Conversion Date at issue. Shares of Preferred Stock
      converted into Common Stock or redeemed in accordance with the terms hereof
      shall be canceled and shall not be reissued.

    


    b)  Conversion
      Price.
      The
      conversion price for the Preferred Stock shall equal $0.25,
      subject
      to adjustment herein (the “Conversion
      Price”).

    


    c)  Beneficial
      Ownership Limitation. The
      Corporation shall not effect any conversion of the Preferred Stock, and a Holder
      shall not have the right to convert any portion of the Preferred Stock, to
      the
      extent that, after giving effect to the conversion set forth on the applicable
      Notice of Conversion, such Holder (together with such Holder’s Affiliates, and
      any other person or entity acting as a group together with such Holder or any
      of
      such Holder’s Affiliates) would beneficially own in excess of the Beneficial
      Ownership Limitation (as defined below).  For purposes of the foregoing
      sentence, the number of shares of Common Stock beneficially owned by such Holder
      and its Affiliates shall include the number of shares of Common Stock issuable
      upon conversion of the Preferred Stock with respect to which such determination
      is being made, but shall exclude the number of shares of Common Stock which
      are
      issuable upon (A) conversion of the remaining, unconverted Stated Value of
      Preferred Stock beneficially owned by such Holder or any of its Affiliates
      and
      (B) exercise or conversion of the unexercised or unconverted portion of any
      other securities of the Corporation subject to a limitation on conversion or
      exercise analogous to the limitation contained herein (including the Warrants)
      beneficially owned by such Holder or any of its Affiliates.  Except as set
      forth in the preceding sentence, for purposes of this Section 6(c), beneficial
      ownership shall be calculated in accordance with Section 13(d) of the Exchange
      Act and the rules and regulations promulgated thereunder. To the extent that
      the
      limitation contained in this Section 6(c) applies, the determination of whether
      the Preferred Stock is convertible (in relation to other securities owned by
      such Holder together with any Affiliates) and of how many shares of Preferred
      Stock are convertible shall be in the sole discretion of such Holder, and the
      submission of a Notice of Conversion shall be deemed to be such Holder’s
      determination of whether the shares of Preferred Stock may be converted (in
      relation to other securities owned by such Holder together with any Affiliates)
      and how many shares of the Preferred Stock are convertible, in each case subject
      to such aggregate percentage limitations. To ensure compliance with this
      restriction, each Holder will be deemed to represent to the Corporation each
      time it delivers a Notice of Conversion that such Notice of Conversion has
      not
      violated the restrictions set forth in this paragraph and the Corporation shall
      have no obligation to verify or confirm the accuracy of such determination.
      In
      addition, a determination as to any group status as contemplated above shall
      be
      determined in accordance with Section 13(d) of the Exchange Act and
      the
      rules and regulations promulgated thereunder.
      For
      purposes of this Section 6(c), in determining the number of outstanding shares
      of Common Stock, a Holder may rely on the number of outstanding shares of Common
      Stock as stated in the most recent of the 

     

    
      
        
        

      

      
        10

        
          

        

      

      
        
        

      

    

    following:
      (A) the Corporation’s most recent Form 10-QSB or Form 10-KSB, as the case may
      be, (B) a more recent public announcement by the Corporation or (C) a more
      recent notice by the Corporation or the Corporation’s transfer agent setting
      forth the number of shares of Common Stock outstanding.  Upon the written
      or oral request of a Holder, the Corporation shall within two Trading Days
      confirm orally and in writing to such 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 Corporation, including the Preferred Stock, by
      such Holder or its Affiliates since the date as of which such number of
      outstanding shares of Common Stock was reported. The “Beneficial Ownership
      Limitation” shall be 4.99% of the number of shares of the Common Stock
      outstanding immediately after giving effect to the issuance of shares of Common
      Stock issuable upon conversion of Preferred Stock held by the applicable Holder.
      The Beneficial Ownership Limitation provisions of this Section 6(c) may be
      waived by such Holder, at the election of such Holder, upon not less than 61
      days’ prior notice to the Corporation, to change the Beneficial Ownership
      Limitation to 9.99% of the number of shares of the Common Stock outstanding
      immediately after giving effect to the issuance of shares of Common Stock upon
      conversion of Preferred Stock held by the applicable Holder and the provisions
      of this Section 6(c) shall continue to apply. Upon such a change by a Holder
      of
      the Beneficial Ownership Limitation from such 4.99% limitation to such 9.99%
      limitation, the Beneficial Ownership Limitation shall not be further waived
      by
      such Holder. The provisions of this paragraph shall be construed and implemented
      in a manner otherwise than in strict conformity with the terms of this Section
      6(c) to correct this paragraph (or any portion hereof) which may be defective
      or
      inconsistent with the intended Beneficial Ownership Limitation herein contained
      or to make changes or supplements necessary or desirable to properly give effect
      to such limitation. The
      limitations contained in this paragraph shall apply to a successor holder of
      Preferred Stock.

    


    d)  [RESERVED].

    


    e)  Mechanics
      of Conversion

    


    i.  Delivery
      of Certificate Upon Conversion.
      Not
      later than three Trading Days after each Conversion Date (the “Share
      Delivery Date”),
      the
      Corporation shall deliver, or cause to be delivered, to the converting Holder
      (A) a certificate or certificates which, on or after the Effective Date, shall
      be free of restrictive legends and trading restrictions (other than those which
      may then be required by the Purchase Agreement) representing the number of
      shares of Common Stock being acquired upon the conversion of shares of Preferred
      Stock, and (B) a bank check in the amount of accrued and unpaid dividends (if
      the Corporation has elected or is required to pay accrued dividends in cash).
      On
      or after the Effective Date, the Corporation shall, upon request of such Holder,
      use its best efforts to deliver any certificate or certificates required to
      be
      delivered by the Corporation under this Section 6 electronically through the
      Depository Trust Company or another established clearing corporation performing
      similar 

     

    
      
        
        

      

      
        11

        
          

        

      

      
        
        

      

    

    functions.
      If in the case of any Notice of Conversion such certificate or certificates
      are
      not delivered to or as directed by the applicable Holder by the third Trading
      Day after the Conversion Date, the applicable Holder shall be entitled to elect
      by written notice to the Corporation at any time on or before its receipt of
      such certificate or certificates, to rescind such Conversion Notice by written
      notice to the Corporation, in which event the Corporation shall promptly return
      to such Holder any original Preferred Stock certificate delivered to the
      Corporation and such Holder shall promptly return any Common Stock certificates
      representing the shares of Preferred Stock tendered for conversion to the
      Corporation.

     

    ii.  Obligation
      Absolute; Partial Liquidated Damages.
      The
      Corporation’s obligation to issue and deliver the Conversion Shares upon
      conversion of Preferred Stock in accordance with the terms hereof are absolute
      and unconditional, irrespective of any action or inaction by a Holder to enforce
      the same, any waiver or consent with respect to any provision hereof, the
      recovery of any judgment against any Person or any action to enforce the same,
      or any setoff, counterclaim, recoupment, limitation or termination, or any
      breach or alleged breach by such Holder or any other Person of any obligation
      to
      the Corporation or any violation or alleged violation of law by such Holder
      or
      any other person, and irrespective of any other circumstance which might
      otherwise limit such obligation of the Corporation to such Holder in connection
      with the issuance of such Conversion Shares; provided,
      however,
      that
      such delivery shall not operate as a waiver by the Corporation of any such
      action that the Corporation may have against such Holder. In the event a Holder
      shall elect to convert any or all of the Stated Value of its Preferred Stock,
      the Corporation may not refuse conversion based on any claim that such Holder
      or
      any one associated or affiliated with such Holder has been engaged in any
      violation of law, agreement or for any other reason, unless an injunction from
      a
      court, on notice to Holder, restraining and/or enjoining conversion of all
      or
      part of the Preferred Stock of such Holder shall have been sought and obtained,
      and the Corporation posts a surety bond for the benefit of such Holder in the
      amount of 150% of the Stated Value of Preferred Stock which is subject to the
      injunction, which bond shall remain in effect until the completion of
      arbitration/litigation of the underlying dispute and the proceeds of which
      shall
      be payable to such Holder to the extent it obtains judgment. In the absence
      of
      such injunction, the Corporation shall issue Conversion Shares and, if
      applicable, cash, upon a properly noticed conversion. If the Corporation fails
      to deliver to a Holder such certificate or certificates pursuant to Section
      6(e)(i) on the second Trading Day after the Share Delivery Date applicable
      to
      such conversion, the Corporation shall pay to such Holder, in cash, as
      liquidated damages and not as a penalty, for each $5,000 of Stated Value of
      Preferred Stock being converted, $50 per Trading Day (increasing to $100 per
      Trading Day on the third Trading Day and increasing to $200 per Trading Day
      on
      the sixth Trading Day after such damages begin to accrue) for each Trading
      Day
      after such second Trading Day after the Share Delivery Date until such
      certificates are delivered.

    Nothing
      herein shall limit a Holder’s right to pursue actual damages or declare a
      Triggering Event pursuant to Section 9 for the Corporation’s failure to deliver
      Conversion Shares within the period specified herein and such Holder shall
      have
      the right to pursue all remedies available to it hereunder, at law or in equity
      including, without limitation, a decree of specific performance and/or
      injunctive relief. The Exercise of any such rights shall not prohibit a Holder
      from seeking to enforce damages pursuant to any other Section hereof or under
      applicable law.

     

    iii.  Compensation
      for Buy-In on Failure to Timely Deliver Certificates Upon
      Conversion.
      If the
      Corporation fails to deliver to a Holder the applicable certificate or
      certificates by the Share Delivery Date pursuant to Section 6(e)(i), and if
      after such Share Delivery Date such Holder is required by its brokerage firm
      to
      purchase (in an open market transaction or otherwise), or the Holder’s brokerage
      firm purchases, shares of Common Stock to deliver in satisfaction of a sale
      by
      such Holder of the Conversion Shares which such Holder was entitled to receive
      upon the conversion relating to such Share Delivery Date (a “Buy-In”),
      then
      the Corporation shall (A) pay in cash to such Holder (in addition to any other
      remedies available to or elected by such Holder) the amount by which (x) such
      Holder’s total purchase price (including any brokerage commissions) for the
      shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate
      number of shares of Common Stock that such Holder was entitled to receive from
      the conversion at issue multiplied by (2) the actual sale price at which the
      sell order giving rise to such purchase obligation was executed (including
      any
      brokerage commissions) and (B) at the option of such Holder, either reissue
      (if
      surrendered) the shares of Preferred Stock equal to the number of shares of
      Preferred Stock submitted for conversion or deliver to such Holder the number
      of
      shares of Common Stock that would have been issued if the Corporation had timely
      complied with its delivery requirements under Section 6(e)(i). For example,
      if a
      Holder purchases shares of Common Stock having a total purchase price of $11,000
      to cover a Buy-In with respect to an attempted conversion of shares of Preferred
      Stock with respect to which the actual sale price (including any brokerage
      commissions) giving rise to such purchase obligation was a total of $10,000
      under clause (A) of the immediately preceding sentence, the Corporation shall
      be
      required to pay such Holder $1,000. The Holder shall provide the Corporation
      written notice indicating the amounts payable to such Holder in respect of
      the
      Buy-In and, upon request of the Corporation, evidence of the amount of such
      loss. Nothing herein shall limit a Holder’s right to pursue any other remedies
      available to it hereunder, at law or in equity including, without limitation,
      a
      decree of specific performance and/or injunctive relief with respect to the
      Corporation’s failure to timely deliver certificates representing shares of
      Common Stock upon conversion of the shares of Preferred Stock as required
      pursuant to the terms hereof.

    iv.  Reservation
      of Shares Issuable Upon Conversion.
      The
      Corporation covenants that it will at all times reserve and keep available
      out
      of its authorized and unissued shares of Common Stock for the sole purpose
      of
      issuance upon conversion of the Preferred Stock and payment of dividends on
      the
      Preferred Stock, each as herein provided, free from preemptive rights or any
      other actual contingent purchase rights of Persons other than the Holders of
      the
      Preferred Stock, not less than such aggregate number of shares of the Common
      Stock as shall (subject to the terms and conditions in the Purchase Agreement)
      be issuable (taking into account the adjustments and restrictions of Section
      7)
      upon the conversion of all outstanding shares of Preferred Stock and payment
      of
      dividends hereunder. The Corporation covenants that all shares of Common Stock
      that shall be so issuable shall, upon issue, be duly authorized, validly issued,
      fully paid and nonassessable and, if the Conversion Shares Registration
      Statement is then effective under the Securities Act, shall be registered for
      public sale in accordance with such Conversion Shares Registration
      Statement.

    


    v.  Fractional
      Shares.
      Upon a
      conversion hereunder, the Corporation shall not be required to issue stock
      certificates representing fractions of shares of Common Stock, but may if
      otherwise permitted, make a cash payment in respect of any final fraction of
      a
      share based on the VWAP at such time. If the Corporation elects not, or is
      unable, to make such a cash payment, the Holders shall be entitled to receive,
      in lieu of the final fraction of a share, one whole share of Common
      Stock.

    


    vi.  Transfer
      Taxes.
      The
      issuance of certificates for shares of the Common Stock on conversion of this
      Preferred Stock shall be made without charge to any Holder for any documentary
      stamp or similar taxes that may be payable in respect of the issue or delivery
      of such certificates, provided that the Corporation shall not be required to
      pay
      any tax that may be payable in respect of any transfer involved in the issuance
      and delivery of any such certificate upon conversion in a name other than that
      of the Holders of such shares of Preferred Stock so converted and the
      Corporation shall not be required to issue or deliver such certificates unless
      or until the Person or Persons requesting the issuance thereof shall have paid
      to the Corporation the amount of such tax or shall have established to the
      satisfaction of the Corporation that such tax has been paid.

    


    Section
      7.
       Certain
      Adjustments.

    


    a)  Stock
      Dividends and Stock Splits.
      If the
      Corporation, at any time while this Preferred Stock is outstanding: (A) pays
      a
      stock dividend or otherwise makes a distribution or distributions payable in
      shares of Common Stock on shares of Common Stock or any other Common Stock
      Equivalents (which, for avoidance of doubt, shall not include any shares of
      Common Stock issued by the Corporation upon conversion of, or payment of a
      dividend on, this Preferred Stock); (B) subdivides outstanding shares of


     

    
      
        
        

      

      
        14

        
          

        

      

      
        
        

      

    

    Common
      Stock into a larger number of shares; (C) combines (including by way of a
      reverse stock split) outstanding shares of Common Stock into a smaller number
      of
      shares; or (D) issues, in the event of a reclassification of shares of the
      Common Stock, any shares of capital stock of the Corporation, then the
      Conversion Price shall be multiplied by a fraction of which the numerator shall
      be the number of shares of Common Stock (excluding any treasury shares of the
      Corporation) outstanding immediately before such event and of which the
      denominator shall be the number of shares of Common Stock outstanding
      immediately after such event. Any adjustment made pursuant to this Section
      7(a)
      shall become effective immediately after the record date for the determination
      of stockholders entitled to receive such dividend or distribution and shall
      become effective immediately after the effective date in the case of a
      subdivision, combination or reclassification.

     

    b)  Subsequent
      Equity Sales.
      If, at
      any time while this Preferred Stock is outstanding, the Corporation or any
      Subsidiary, as applicable, sells or grants any option to purchase or sells
      or
      grants any right to reprice its securities, or otherwise disposes of or issues
      (or announces any sale, grant or any option to purchase or other disposition)
      any Common Stock or Common Stock Equivalents entitling any Person to acquire
      shares of Common Stock at an effective price per share that is lower than the
      then Conversion Price (such lower price, the “Base
      Conversion Price”
and
      such issuances collectively, a “Dilutive
      Issuance”)
      (if
      the holder of the Common Stock or Common Stock Equivalents so issued shall
      at
      any time, whether by operation of purchase price adjustments, reset provisions,
      floating conversion, exercise or exchange prices or otherwise, or due to
      warrants, options or rights per share which are issued in connection with such
      issuance, be entitled to receive shares of Common Stock at an effective price
      per share that is lower than the Conversion Price, such issuance shall be deemed
      to have occurred for less than the Conversion Price on such date of the Dilutive
      Issuance), then the Conversion Price shall be reduced to equal the Base
      Conversion Price. Notwithstanding
      the foregoing, no adjustment will be made under this Section 7(b) in respect
      of
      an Exempt Issuance.
      The
      Corporation shall notify the Holders in writing, no later than the third
      Business Day following the issuance of any Common Stock or Common Stock
      Equivalents subject to this Section 7(b), indicating therein the applicable
      issuance price, or applicable reset price, exchange price, conversion price
      and
      other pricing terms (such notice, the “Dilutive
      Issuance Notice”).
      For
      purposes of clarification, whether or not the Corporation provides a Dilutive
      Issuance Notice pursuant to this Section 7(b), upon the occurrence of any
      Dilutive Issuance, the Holders are entitled to receive a number of Conversion
      Shares based upon the Base Conversion Price on or after the date of such
      Dilutive Issuance, regardless of whether a Holder accurately refers to the
      Base
      Conversion Price in the Notice of Conversion. 

     

    c)  Subsequent
      Rights Offerings.
      If the
      Corporation, at any time while this Preferred Stock is outstanding, shall issue
      rights, options or warrants to all holders of Common Stock (and not to Holders)
      entitling them to subscribe for or purchase shares of Common Stock at a price
      per share that is lower than the VWAP on the record date referenced below,
      then
      the Conversion Price shall be multiplied by a fraction of which 

     

    
      
        
        

      

      
        15

        
          

        

      

      
        
        

      

    

    the
      denominator shall be the number of shares of the Common Stock outstanding on
      the
      date of issuance of such rights or warrants plus the number of additional shares
      of Common Stock offered for subscription or purchase, and of which the numerator
      shall be the number of shares of the Common Stock outstanding on the date of
      issuance of such rights or warrants plus the number of shares which the
      aggregate offering price of the total number of shares so offered (assuming
      delivery to the Corporation in full of all consideration payable upon exercise
      of such rights, options or warrants) would purchase at such VWAP. Such
      adjustment shall be made whenever such rights or warrants are issued, and shall
      become effective immediately after the record date for the determination of
      stockholders entitled to receive such rights, options or warrants.

     

    d)  Pro
      Rata Distributions.
      If the
      Corporation, at any time while this Preferred Stock is outstanding, distributes
      to all holders of Common Stock (and not to Holders) evidences of its
      indebtedness or assets (including cash and cash dividends) or rights or warrants
      to subscribe for or purchase any security (other than Common Stock, which shall
      be subject to Section 7(b)), then in each such case the Conversion Price shall
      be adjusted by multiplying such Conversion Price in effect immediately prior
      to
      the record date fixed for determination of stockholders entitled to receive
      such
      distribution by a fraction of which the denominator shall be the VWAP determined
      as of the record date mentioned above, and of which the numerator shall be
      such
      VWAP on such record date less the then fair market value at such record date
      of
      the portion of such assets, evidence of indebtedness or rights or warrants
      so
      distributed applicable to one outstanding share of the Common Stock as
      determined by the Board of Directors of the Corporation in good faith. In either
      case the adjustments shall be described in a statement delivered to the Holders
      describing the portion of assets or evidences of indebtedness so distributed
      or
      such subscription rights applicable to one share of Common Stock. Such
      adjustment shall be made whenever any such distribution is made and shall become
      effective immediately after the record date mentioned above.

    


    e)  Fundamental
      Transaction.
      If, at
      any time while this Preferred Stock is outstanding, (A) the Corporation effects
      any merger or consolidation of the Corporation with or into another Person,
      (B)
      the Corporation effects any sale of all or substantially all of its assets
      in
      one transaction or a series of related transactions, (C) any tender offer or
      exchange offer (whether by the Corporation or another Person) is completed
      pursuant to which holders of Common Stock are permitted to tender or exchange
      their shares for other securities, cash or property, or (D) the Corporation
      effects any reclassification of the Common Stock or any compulsory share
      exchange pursuant to which the Common Stock is effectively converted into or
      exchanged for other securities, cash or property (in any such case, a
“Fundamental
      Transaction”),
      then,
      upon any subsequent conversion of this Preferred Stock, the Holders shall have
      the right to receive, for each Conversion Share that would have been issuable
      upon such conversion immediately prior to the occurrence of such Fundamental
      Transaction, the same kind and amount of securities, cash or property as it
      would have been entitled to receive upon the occurrence of such Fundamental
      Transaction if it had been, immediately prior to such Fundamental Transaction,
      the holder of one share of Common Stock (the “Alternate
      Consideration”). 
      

     

    
      
        
        

      

      
        16

        
          

        

      

      
        
        

      

    

    For
      purposes of any such conversion, the determination of the Conversion Price
      shall
      be appropriately adjusted to apply to such Alternate Consideration based on
      the
      amount of Alternate Consideration issuable in respect of one share of Common
      Stock in such Fundamental Transaction, and the Corporation shall apportion
      the
      Conversion Price among the Alternate Consideration in a reasonable manner
      reflecting the relative value of any different components of the Alternate
      Consideration. If holders of Common Stock are given any choice as to the
      securities, cash or property to be received in a Fundamental Transaction, then
      the Holders shall be given the same choice as to the Alternate Consideration
      it
      receives upon any conversion of this Preferred Stock following such Fundamental
      Transaction. To the extent necessary to effectuate the foregoing provisions,
      any
      successor to the Corporation or surviving entity in such Fundamental Transaction
      shall file a new Certificate of Designation with the same terms and conditions
      and issue to the Holders new preferred stock consistent with the foregoing
      provisions and evidencing the Holders’ right to convert such preferred stock
      into Alternate Consideration. The terms of any agreement pursuant to which
      a
      Fundamental Transaction is effected shall include terms requiring any such
      successor or surviving entity to comply with the provisions of this Section
      7(e)
      and insuring that this Preferred Stock (or any such replacement security) will
      be similarly adjusted upon any subsequent transaction analogous to a Fundamental
      Transaction.

     

    f)  Calculations.
      All
      calculations under this Section 7 shall be made to the nearest cent or the
      nearest 1/100th of a share, as the case may be. For purposes of this Section
      7,
      the number of shares of Common Stock deemed to be issued and outstanding as
      of a
      given date shall be the sum of the number of shares of Common Stock (excluding
      any treasury shares of the Corporation) issued and outstanding.

    


    g)  Notice
      to the Holders.

    


    i.  Adjustment
      to Conversion Price.
      Whenever the Conversion Price is adjusted pursuant to any provision of this
      Section 7, the Corporation shall promptly mail to each Holder a notice setting
      forth the Conversion Price after such adjustment and setting forth a brief
      statement of the facts requiring such adjustment. If the Corporation issues
      a
      variable rate security, despite the prohibition thereon in the Purchase
      Agreement, the Corporation shall be deemed to have issued Common Stock or Common
      Stock Equivalents at the lowest possible conversion or exercise price at which
      such securities may be converted or exercised in the case of a Variable Rate
      Transaction (as defined in the Purchase Agreement).

     

    ii.  Notice
      to Allow Conversion by Holder.
      If (A)
      the Corporation shall declare a dividend (or any other distribution in whatever
      form) on the Common Stock, (B) the Corporation shall declare a special
      nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
      Corporation shall authorize the granting to all holders of the Common Stock
      of
      rights or warrants to subscribe for or purchase any shares of capital stock
      of
      any class or of any rights, 

     

    
      
        
        

      

      
        17

        
          

        

      

      
        
        

      

    

    (D)
      the
      approval of any stockholders of the Corporation shall be required in connection
      with any reclassification of the Common Stock, any consolidation or merger
      to
      which the Corporation is a party, any sale or transfer of all or substantially
      all of the assets of the Corporation, of any compulsory share exchange whereby
      the Common Stock is converted into other securities, cash or property or (E)
      the
      Corporation shall authorize the voluntary or involuntary dissolution,
      liquidation or winding up of the affairs of the Corporation, then, in each
      case,
      the Corporation shall cause to be filed at each office or agency maintained
      for
      the purpose of conversion of this Preferred Stock, and shall cause to be
delivered
      to each Holder at its last address as it shall appear upon the stock
      books of
      the
      Corporation, at least 20 calendar days prior to the applicable record or
      effective date hereinafter specified, a notice stating (x)
      the
      date on which a record is to be taken for the purpose of such dividend,
      distribution, redemption, rights or warrants, or if a record is not to be taken,
      the date as of which the holders of the Common Stock of record to be entitled
      to
      such dividend, distributions, redemption, rights or warrants are to be
      determined or (y) the date on which such reclassification, consolidation,
      merger, sale, transfer or share exchange is expected to become effective or
      close, and the date as of which it is expected that holders of the Common Stock
      of record shall be entitled to exchange their shares of the Common Stock for
      securities, cash or other property deliverable upon such reclassification,
      consolidation, merger, sale, transfer or share exchange, provided that the
      failure to deliver such notice or any defect therein or in the delivery thereof
      shall not affect the validity of the corporate action required to be specified
      in such notice. The Holder is entitled to convert the Conversion Amount of
      this
      Preferred Stock (or any part hereof) during the 20-day period commencing on
      the
      date of such notice through the effective date of the event triggering such
      notice. 

     

    Section
      8.
       Force
      Conversion.
      The
      Corporation shall have the following rights to force a conversion of the
      Preferred Stock if after the Effective Date, each of the closing bid price
      for
      any 20 consecutive Trading Days (such 20 day period commencing only after the
      later of the Effective Date, such period the “Threshold
      Period”))
      exceeds $1.25 (as appropriately adjusted for stock splits and combinations),
      the
      Corporation may, within 1 Trading Day of the end of any such Threshold Period,
      deliver a notice to the Holder (a “Forced
      Conversion Notice”
and
      the
      date such notice is received by the Holder, the “Forced
      Conversion Notice Date”)
      to
      cause the Holder to immediately convert all or part of the then outstanding
      Stated Value amount of Preferred Stocks. The Corporation may only effect a
      Forced Conversion Notice if all of the Equity Conditions are met through the
      applicable Threshold Period until the date of the applicable Forced Conversion
      and through and including the date such shares of Common Stock are issued to
      the
      Holder. Any Forced Conversion shall be applied ratably to all Holders based
      on
      their initial purchases of Preferred Stocks pursuant to the Purchase Agreement.
      For purposes of clarification, a Forced Conversion shall be subject to all
      of
      the provisions of Section 5, including, without limitation, the provision
      requiring payment of liquidated damages and limitations on conversions.

    Section
      9.
       Redemption
      Upon Triggering Events.

     

    a)  “Triggering
      Event”
means
      any one or more of the following events (whatever the reason and whether it
      shall be voluntary or involuntary or effected by operation of law or pursuant
      to
      any judgment, decree or order of any court, or any order, rule or regulation
      of
      any administrative or governmental body):

    


    i.  RESERVED;

     

    ii.  RESERVED;
      

    


    iii.  the
      Corporation shall fail to deliver certificates representing Conversion Shares
      issuable upon a conversion hereunder that comply with the provisions hereof
      prior to the fifth Trading Day after such shares are required to be delivered
      hereunder, or the Corporation shall provide written notice to any Holder,
      including by way of public announcement, at any time, of its intention not
      to

      accordance with the terms hereof;

    


    iv.  RESERVED;

    


    v.  the
      Corporation shall fail for any reason to pay in full the amount of cash due
      pursuant to a Buy-In within five calendar days after notice therefor is
      delivered hereunder or shall fail to pay all amounts owed on account of any
      Event (as defined in the Registration Rights Agreement) within five days of
      the
      date due;

    


    vi.  the
      Corporation shall fail to have available a sufficient number of authorized
      and
      unreserved shares of Common Stock to issue to such Holder upon a conversion
      hereunder;

    


    vii.  unless
      specifically addressed elsewhere in this Certificate of Designation as a
      Triggering Event, the Corporation shall fail to observe or perform any other
      covenant, agreement or warranty contained in, or otherwise commit any breach
      of
      the Transaction Documents, and such failure or breach shall not, if subject
      to
      the possibility of a cure by the Corporation, have been cured within 30 calendar
      days after the date on which written notice of such failure or breach shall
      have
      been delivered;

    


    viii.  the
      Corporation shall redeem more than a de minimis
      number
      of Junior Securities other than as to repurchases of Common Stock or Common
      Stock Equivalents from departing officers and directors of the Corporation,
      provided that, while any of the Preferred Stock remains outstanding,
      such

     

    
      
        
        

      

      
        19

        
          

        

      

      
        
        

      

    

    repurchases
      shall not exceed an aggregate of $200,000 from all officers and
      directors;

    


    ix.  the
      Corporation shall be party to a Change of Control Transaction; 

    


    x.  there
      shall have occurred a Bankruptcy Event;

    xii.  any
      monetary judgment, writ or similar final process shall be entered or filed
      against the Corporation, any Subsidiary or any of their respective property
      or
      other assets for greater than $200,000, and such judgment, writ or similar
      final
      process shall remain unvacated, unbonded or unstayed for a period of 45 calendar
      days.

    


    b)  Upon
      the
      occurrence of a Triggering Event, each Holder shall (in addition to all other
      rights it may have hereunder or under applicable law) have the right,
      exercisable at the sole option of such Holder, to require the Corporation to,
      (A) with respect to the Triggering Events set forth in Sections 9(a)(iii),
      (v),
      (vi), (vii), (viii), (ix), (ix) (as to Changes of Control approved by the Board
      of Directors of the Corporation) and (x) (as to voluntary filings only), redeem
      all of the Preferred Stock then held by such Holder for a redemption price,
      in
      cash, equal to the Triggering Redemption Amount or (B) at the option of each
      Holder and with respect to the Triggering Events set forth in Sections 9(a)(i),
      (ii), (iv), (ix) (as to Changes of Control not approved by the Board of
      Directors of the Corporation), (x) (as to involuntary filings only) and (xii),
      either (a) redeem all of the Preferred Stock then held by such Holder for a
      redemption price, in shares of Common Stock, equal to a number of shares of
      Common Stock equal to the Triggering Redemption Amount divided by 90% of the
      average of the 10 VWAPs immediately prior to the date of election hereunder
      or
      (b) increase the dividend rate on all of the outstanding Preferred Stock held
      by
      such Holder to 18% per annum thereafter. The Triggering Redemption Amount,
      in
      cash or in shares, shall be due and payable or issuable, as the case may be,
      within five Trading Days of the date on which the notice for the payment
      therefor is provided by a Holder (the “Triggering
      Redemption Payment Date”).
      If
      the Corporation fails to pay in full the Triggering Redemption Amount hereunder
      on the date such amount is due in accordance with this Section (whether in
      cash
      or shares of Common Stock), the Corporation will pay interest thereon at a
      rate
      equal to the lesser of 18% per annum or the maximum rate permitted by applicable
      law, accruing daily from such date until the Triggering Redemption Amount,
      plus
      all such interest thereon, is paid in full. For purposes of this Section, a
      share of Preferred Stock is outstanding until such date as the applicable Holder
      shall have received Conversion Shares upon a conversion (or attempted
      conversion) thereof that meets the requirements hereof or has been paid the
      Triggering Redemption Amount in cash.

    Section
      10.
       Negative
      Covenants.
      So long
      as any shares of Preferred Stock are outstanding, the Corporation shall not,
      and
      shall not permit any of its Subsidiaries to, directly or
      indirectly:

    


    a)  other
      than Permitted Indebtedness, enter into, create, incur, assume, guarantee or
      suffer to exist any indebtedness for borrowed money of any kind, including
      but
      not limited to, a guarantee, on or with respect to any of its property or assets
      now owned or hereafter acquired or any interest therein or any income or profits
      therefrom;

     

    b)  other
      than Permitted Liens, enter into, create, incur, assume or suffer to exist
      any
      Liens of any kind, on or with respect to any of its property or assets now
      owned
      or hereafter acquired or any interest therein or any income or profits
      therefrom;

    


    c)  amend
      its
      certificate of incorporation, bylaws or other charter documents so as to

    d)  Governing
      Law.
      All
      questions concerning the construction, validity, enforcement and interpretation
      of this Certificate of Designation shall be governed by and construed and
      enforced in accordance with the internal laws of the State of [name of state
      of
      incorporation], without regard to the principles of conflict of laws thereof.
      Each party agrees that all legal proceedings concerning the interpretation,
      enforcement and defense of the transactions contemplated by any of the
      Transaction Documents (whether brought against a party hereto or its respective
      Affiliates, directors, officers, shareholders, employees or agents) shall be
      commenced in the state and federal courts sitting in the City of New York,
      Borough of Manhattan (the “New
      York Courts”).
      Each
      party hereto hereby irrevocably submits to the exclusive jurisdiction of the
      New
      York Courts for the adjudication of any dispute hereunder or in connection
      herewith or with any transaction contemplated hereby or discussed herein
      (including with respect to the enforcement of any of the Transaction Documents),
      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
      such New York Courts, or such New York Courts are improper or inconvenient
      venue
      for such proceeding. Each party hereby irrevocably waives personal service
      of
      process and consents to process being served in any such suit, action or
      proceeding by mailing a copy thereof via registered or certified mail or
      overnight delivery (with evidence of delivery) to such party at the address
      in
      effect for notices to it under this Certificate of Designation and agrees that
      such service shall constitute good and sufficient service of process and notice
      thereof. Nothing contained herein shall be deemed to limit in any way any right
      to serve process in any other manner permitted by

     

    
      
        
        

      

      
        22

        
          

        

      

      
        
        

      

    

    applicable
      law. Each party hereto hereby irrevocably waives, to the fullest extent
      permitted by applicable law, any and all right to trial by jury in any legal
      proceeding arising out of or relating to this Certificate of Designation or
      the
      transactions contemplated hereby. If either party shall commence an action
      or
      proceeding to enforce any provisions of this Certificate of Designation, then
      the prevailing party in such action or proceeding shall be reimbursed by the
      other party for its attorneys’ fees and other costs and expenses incurred in the
      investigation, preparation and prosecution of such action or
      proceeding.

     

    e)  Waiver.
      Any
      waiver by the Corporation or a Holder of a breach of any provision of this
      Certificate of Designation shall not operate as or be construed to be a waiver
      of any other breach of such provision or of any breach of any other provision
      of
      this Certificate of Designation or a waiver by any other Holders. The failure
      of
      the Corporation or a Holder to insist upon strict adherence to any term of
      this
      Certificate of Designation on one or more occasions shall not be considered
      a
      waiver or deprive that party (or any other Holder) of the right thereafter
      to
      insist upon strict adherence to that term or any other term of this Certificate
      of Designation. Any waiver by the Corporation or a Holder must be in
      writing.

     

    f)  Severability.
      If any
      provision of this Certificate of Designation is invalid, illegal or
      unenforceable, the balance of this Certificate of Designation shall remain
      in
      effect, and if any provision is inapplicable to any Person or circumstance,
      it
      shall nevertheless remain applicable to all other Persons and circumstances.
      If
      it shall be found that any interest or other amount deemed interest due
      hereunder violates the applicable law governing usury, the applicable rate
      of
      interest due hereunder shall automatically be lowered to equal the maximum
      rate
      of interest permitted under applicable law. 

    


    g)  Next
      Business Day.
      Whenever any payment or other obligation hereunder shall be due on a day other
      than a Business Day, such payment shall be made on the next succeeding Business
      Day.

    


    h)  Headings.
      The
      headings contained herein are for convenience only, do not constitute a part
      of
      this Certificate of Designation and shall not be deemed to limit or affect
      any
      of the provisions hereof.

    


    i)  Status
      of Converted or Redeemed Preferred Stock.
      Shares
      of Preferred Stock may only be issued pursuant to the Purchase Agreement. If
      any
      shares of Preferred Stock shall be converted, redeemed or reacquired by the
      Corporation, such shares shall resume the status of authorized but unissued
      shares of preferred stock and shall no longer be designated as Series A
      Preferred Stock.
