FOR VALUE RECEIVED, the undersigned promises unconditionally to PAY TO THE ORDER
OF

         Stellar McKim LLC, a Delaware limited liability company,  the principal
sum of one million and eight hundred thousand  ($1,800,000.00)  dollars together
with the interest thereon from January 4, 2006, at the rate of nine (9%) percent
per annum until  maturity,  all payable in lawful money of the United  States of
America, as follows:

         interest to be paid on annually  beginning  on January 4, 2007,  and on
         the same date every year thereafter  until all amounts of principal and
         interest  then due and owing  shall  have  been paid in full;  provided
         further that all amounts of principal  and interest  then due and owing
         shall be paid on or before  January 4, 2009.  Principal  may be paid in
         whole or in part without penalty  (provided that any partial payment of
         principal shall be at least  $100,000.00 in amount).  Prior  provisions
         notwithstanding,  any amount of  principal  and  interest  then due and
         owing may be paid at the option of the maker in  correspondingly-valued
         shares of common stock issued by the maker and having a per-share value
         of such  common  stock  determined  as  follows  for  purposes  of such
         optional  payment under this promissory note: the total value of all of
         such stock publicly-traded  during the preceding twenty trading days of
         the  exchange  on which such  shares  are  traded  divided by the total
         number of such shares of common stock traded on those days. Conflicting
         provisions notwithstanding,  nothing herein shall entitle any holder to
         any usurious  rate or amount of interest and any interest  deemed to be
         usurious under  applicable law shall be considered  first to be payment
         of then-unpaid principal of,  alternatively,  shall be considered to be
         refundable to the party paying such interest.

All payments shall apply first to accrued interest,  and the remainder,  if any,
to reduction of principal.  If any  installment  of principal or interest is not
paid when due, or upon any default in the performance of any of the covenants or
agreements of this note,  or of any  instrument  now or hereafter  evidencing or
securing this note or the obligation  represented hereby, the whole indebtedness
(including principal and interest) remaining unpaid, shall, at the option of the
holder,  become immediately due, payable and collectible,  and while in default,
this note and deferred  interest  shall bear  interest at the highest  legal and
non-usurious rate under applicable law. Each maker and endorser severally waives
demand,  protest  and  notice  of  maturity,  non-payment  or  protest  and  all
requirements necessary to hold each of them liable as makers and endorsers. Each
maker and endorser  further agrees,  jointly and severally,  to pay all costs of
collection,  including  reasonable  attorney  fees in case the principal of this
note or any payment on the principal or any interest  thereon is not paid at the
respective  maturity  thereof,  or in case it becomes  necessary  to protect the
security hereof, whether suit be brought or not.

      whether voluntary or involuntary, to the Series A Preferred Stock, Series C
      Preferred Stock, and Series D Preferred Stock, Series E Preferred Stock,
      and Series F Preferred Stock .

    

    4. Dividends.

    

    (a) The
      holders of shares of Series G Preferred Stock shall be entitled to receive,
      when, as and if declared by the Board of Directors of the Company, cumulative
      dividends out of funds legally available therefor, at the annual rate of $0.40
      per annum on each outstanding share of Series G Preferred Stock (as
      appropriately adjusted for stock splits, stock dividends, combinations,
      recapitalizations and the like with respect to the Series G Preferred Stock)
      (the "Annual
      Dividend Rate").
      Such
      dividends shall cumulate from the date issued and be paid when, as and if
      declared, annually on November 1st
      of each
      year commencing on November 1, 2006 (each of such dates being a "Series
      G Dividend Payment Date"
      and
      each period between such dates or the date of issue, if earlier, being a
      "Series
      G Dividend Period")
      to the
      shareholders of record of Series G Preferred Stock on the respective date,
      not
      exceeding 15 days preceding such Series G Dividend Payment Date, as shall be
      fixed for this purpose by the Board of Directors of the Company in advance
      of
      payment of each particular dividend. Dividend payments made with respect to
      shares of Series G Preferred Stock shall be made in cash, fully paid and
      nonassessable shares of Common Stock, or a contribution thereof, at the
      Company's discretion. For purposes of determining the number of shares of Common
      Stock issuable in connection with a Series G Dividend Period, the value of
      each
      share of Common Stock shall be equal to the average closing price for such
      stock
      over the 30 day period preceding the Series G Dividend Payment Date, as quoted
      on The NASDAQ Stock Market and reported in the Wall
      Street Journal,
      or so
      long as the Common Stock is traded on the over-the-counter market, as reported
      by such system (the "Dividend
      Share Price")
      The
      amount of dividends payable for the initial dividend period and any period
      shorter than 1 year Series G Dividend Period shall be computed on the basis
      of a
      360-day year of twelve 30-day months.

    

    
      
         

      

      
        -2-

        
          

        

      

      
         

      

    

    (b) All
      dividends paid in shares of Common Stock pursuant to subparagraph (a) shall
      be
      paid pro rata to the holders entitled thereto. Notwithstanding Section 4(a)
      above, in lieu of issuing fractional shares of Common Stock in connection with
      payment of a dividend for a Series G Dividend Period, any portion of such
      dividend which would otherwise result in distribution of a fractional share
      of
      Common Stock shall be paid in cash in an amount equal to the product of such
      fraction and the Dividend Share Price. All shares of Common Stock which may
      be
      issued as a dividend with respect to the Series G Preferred Stock will thereupon
      be duly authorized, validly issued, fully paid and nonassessable. 

    

    (c) Holders
      of Series G Preferred Stock will not be entitled to any dividends, whether
      payable in cash, property or stock, in excess of the full cumulative dividends.
      No interest or sum of money in lieu of interest shall be payable in respect
      of
      any accumulated unpaid dividends.

    

    (d) No
      dividends or other distributions shall be declared, paid or set apart for
      payment on shares of Junior Stock or any other capital stock of the Company
      ranking junior as to dividends to the Series G Preferred Stock (the Junior
      Stock
      and any such other class or series of the Company's capital stock, other than
      the Series A Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock, Series E Preferred Stock, and Series F Preferred Stock being
      herein referred to as "Junior
      Dividend Stock"),
      unless full cumulative dividends have been, or contemporaneously are, paid
      or
      declared and set apart for such payment on the Series G Preferred Stock for
      all
      dividend payment periods ending on or before the payment date of such dividends
      on Junior Dividend Stock.

    

    (e) No
      payment on account of the purchase, redemption, retirement or other acquisition
      of shares of Junior Dividend Stock or any other class or series of the Company's
      capital stock ranking junior to the Series G Preferred Stock as to distributions
      of assets upon liquidation, dissolution or winding up of the Company, whether
      voluntary or involuntary (the Junior Stock and any other class or series of
      the
      Company's capital stock ranking junior to the Series G Preferred Stock as to
      such distributions other than the Series A Preferred Stock, Series C
      Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, and
      Series F Preferred Stock being herein referred to as "Junior
      Liquidation Stock")
      shall
      be made for any period unless and until all accrued and unpaid dividends on
      the
      Series G Preferred Stock for all dividend payment periods ending on or before
      such payment for such Junior Dividend Stock or Junior Liquidation Stock (as
      hereinafter defined) shall have been paid or declared and set apart for
      payment.

    

    
      
         

      

      
        -3-

        
          

        

      

      
         

      

    

    (f) No
      dividends or other distributions shall be declared, paid or set apart for
      payment on shares of any class or series of the Company's capital stock
      hereafter issued ranking, as to dividends, on a parity with the Series G
      Preferred Stock (any such class or series of the Company's capital stock being
      herein referred to as "Parity
      Dividend Stock")
      for
      any period unless full cumulative dividends have been, or contemporaneously
      are,
      paid or declared and set apart for such payment on the Series G Preferred Stock
      for all dividend payment periods ending on or before the payment date of such
      dividends on Parity Dividend Stock. No dividends may be paid on Parity Dividend
      Stock except on dates on which dividends are paid on the Series G Preferred
      Stock. All dividends paid or declared and set apart for payment on the Series
      G
      Preferred Stock and the Parity Dividend Stock shall be paid or declared and
      set
      apart for payment pro rata so that the amount of dividends paid or declared
      and
      set apart for payment per share on the Series G Preferred Stock and the Parity
      Dividend Stock on any date shall in all cases bear to each other the same ratio
      that accrued and unpaid dividends to the date of payment on the Series G
      Preferred Stock and the Parity Dividend Stock bear to each other.

    

    (g) No
      payment on account of the purchase, redemption, retirement or other acquisition
      of shares of Parity Dividend Stock or any class or series of the Company's
      capital stock ranking on a parity with the Series G Preferred Stock as to
      distributions of assets upon liquidation, dissolution or winding up of the
      Company, whether voluntary or involuntary (any such class or series of the
      Company's capital stock being herein referred to as "Parity
      Liquidation Stock")
      shall
      be made, and, other than dividends to the extent permitted by the preceding
      paragraph, no distributions shall be declared, paid or set apart for payment
      on
      shares of Parity Dividend Stock or Parity Liquidation Stock, unless and until
      all accrued and unpaid dividends on the Series G Preferred Stock for all
      dividend payment periods ending on or before such payment for, or the payment
      date of such distributions on, such Parity Dividend Stock or Parity, Liquidation
      Stock shall have been paid or declared and set apart for payment; provided,
      however, that the restrictions set forth in this sentence shall not apply to
      the
      purchase or other acquisition of Parity Dividend Stock or Parity Liquidation
      Stock either (A) pursuant to any employee or director incentive or benefit
      plan or arrangement (including any employment, severance or consulting
      agreement) of the Company or any subsidiary of the Company hereafter adopted
      or
      (B) in exchange solely for Junior Stock.

    

    (h) Any
      reference to "distribution" contained in this Section 4 shall not be deemed
      to include any distribution made in connection with any liquidation, dissolution
      or winding up of the Company, whether voluntary or involuntary.

    

    5. Liquidation
      Preference.

    

    (a) In
      the
      event of any liquidation, dissolution or winding up of the Company, whether
      voluntary or involuntary, before any payment or distribution of the assets
      of
      the Company shall be made to or set apart for the holders of Parity Liquidation
      Stock, the holders of Series A Preferred Stock, Series C Preferred
      Stock, Series D Preferred Stock, Series E Preferred Stock, and then
      Series F Preferred Stock (in that order) shall be paid all amounts that
      such holders are entitled with respect to the liquidation and dissolution of
      the
      Company. In the event of any liquidation, dissolution or winding up of the
      Company, whether voluntary or involuntary, before any payments or distribution
      of the assets of the Company shall be made to or set apart for the holders
      of
      Junior Stock, the holders of the Series G Preferred Stock shall be entitled
      to
      receive in immediately available funds the sum of $5.00 per share (as
      appropriately adjusted for stock splits, stock dividends, combinations,
      recapitalizations and the like with respect to the Series G Preferred Stock),
      plus all dividends (whether or not authorized) accumulated and unpaid without
      interest thereon to the date of final distribution to such holders (the
      "Liquidation
      Preference");
      but
      such holders shall not be entitled to any further payment. If, upon any
      liquidation, dissolution or winding up of the Company, the assets of the
      Company, or proceeds thereof, distributable among the holders of the Series
      G
      Preferred Stock shall be insufficient to pay in full the Liquidation Preference
      and liquidating payments on any other shares of any class or series of Parity
      Liquidation Stock, then such assets, or the proceeds thereof, shall be
      distributed among the holders of Series G Preferred Stock and any such other
      Parity Liquidation Stock ratably in accordance with the respective amounts
      that
      would be payable on such shares of Series G Preferred Stock and any such other
      shares of Parity Liquidation Stock if all amounts payable thereon were paid
      in
      full.

    

    
      
         

      

      
        -4-

        
          

        

      

      
         

      

    

    (b) Subject
      to the rights of the holders of shares of Parity Liquidation Stock, after
      payment shall have been made in full to the holders of the Series G Preferred
      Stock, as provided in this Section 5, any other series or class or classes
      of Junior Stock shall, subject to the respective terms and provisions (if any)
      applying thereto, be entitled to receive any and all assets remaining to be
      paid
      or distributed, and the holders of the Series G Preferred Stock shall not be
      entitled to share therein.

    

    (c) For
      purposes of this Section 5, neither the voluntary sale, lease, conveyance,
      exchange, or transfer (for cash, shares of stock, securities, or other
      consideration) of all or substantially all of the property or assets of the
      Company, nor the consolidation or merger of the Company with or into one or
      more
      other corporations, shall be deemed to be a liquidation, dissolution, or winding
      up of the affairs of the Company, unless such voluntary sale, lease, conveyance,
      exchange, or transfer shall be in connection with a plan of liquidation,
      dissolution, or winding up of the affairs of the Company.

    

    6. Conversion.

    

    (a) Optional
      Conversion.
      After
      the initial issuance of the Series G Preferred Stock each share of Series G
      Preferred Stock shall be convertible at the option of the holder thereof, at
      any
      time prior to the close of business on the fifth business day prior to the
      date
      fixed for redemption of such shares as herein provided, into such number of
      fully paid and nonassessable shares of Common Stock as is determined by dividing
      the Original Issue Price by the Conversion Price, determined as hereinafter
      provided, in effect at the time of conversion for the Common Stock and then
      multiplying such quotient by each share of Series G Preferred Stock to be
      converted. For purposes of this resolution, the "Conversion Price" applicable
      per share of Common Stock shall initially be equal to $0.05 and shall be
      adjusted from time to time in accordance with the provisions of this
      Section 6. The number of shares of Common Stock into which each share of
      Series G Preferred Stock may be converted is hereinafter referred to as the

    (b) Automatic
      Conversion.
      Each
      share of Series G Preferred Stock shall automatically be converted into shares
      of Common Stock at the then effective Conversion Rate, upon such date where
      the
      Company's Common Stock has traded at a price of $0.20 (subject to appropriate
      adjustment for stock splits, stock dividends, combinations, recapitalizations
      and the like) or greater per share for 20 consecutive trading days, on the
      basis
      of closing prices of the Common Stock quoted on The NASDAQ Stock Market and
      reported in the Wall
      Street Journal,
      or so
      long as the Common Stock is traded on the over-the-counter market, as reported
      by such system. As used herein, the term "trading day" shall mean a day on
      which
      national stock exchanges and The NASDAQ Stock Market are open for trading of
      securities.

    

    (c) Conversion
      Procedures.
      Any
      holder of shares of Series G Preferred Stock converting such shares into Common
      Stock shall surrender the certificate or certificates evidencing such shares
      of
      Series G Preferred Stock at the office of the transfer agent for the Series
      G
      Preferred Stock, which certificate or certificates, if the Company shall so
      require, shall be duly endorsed to the Company or in blank, or accompanied
      by
      proper instruments of transfer to the Company or in blank, accompanied by
      irrevocable written notice to the Company that the holder elects so to convert
      such shares of Series G Preferred Stock and specifying the name or names (with
      address or addresses) in which a certificate or certificates evidencing shares
      of Common Stock are to be issued; provided, that in the event of an automatic
      conversion pursuant to Section 6(b) hereof, the outstanding shares of Series
      G
      Preferred Stock shall be converted automatically without any further action
      by
      the holders of such shares and whether or not the certificates representing
      such
      shares are surrendered to the Company or its transfer agent; provided, further,
      that the Company shall not be obligated to issue certificates evidencing the
      shares of Common Stock issuable upon such automatic conversion unless either
      the
      certificates evidencing such shares of Series G Preferred Stock are delivered
      to
      the Company or its transfer agent as provided above, or the holder notifies
      the
      Company or its transfer agent that such certificates have been lost, stolen
      or
      destroyed and executes an agreement and provides, if requested by the Company,
      a
      bond satisfactory to the Company to indemnify the Company from any loss incurred
      by it in connection with such certificates.

    

    Subject
      to Section 6(d) hereof, no payments or adjustments in respect of
      accumulated and unpaid dividends on shares of Series G Preferred Stock
      surrendered for conversion or on account of any dividend on the Common Stock
      issued upon conversion shall be made upon the conversion of any shares of Series
      G Preferred Stock; provided, however, that to the extent the Board of Directors
      of the Company have declared prior to the date of conversion payment of any
      accumulated and unpaid dividends on shares of Series G Preferred Stock a holder
      of Series G Preferred Stock shall retain the right to receive such declared
      dividends notwithstanding the conversion of any shares of Series G Preferred
      Stock.

    

    The
      Company shall, as soon as practicable after such deposit of certificates
      evidencing share of Series G Preferred Stock accompanied by the written notice
      and compliance with any other conditions herein contained, deliver at such
      office of such transfer agent to the person for whose account such shares of
      Series G Preferred Stock were so surrendered, or to the nominee or nominees
      of
      such person, certificates evidencing the number of full shares of Common Stock
      to which such person shall be entitled as aforesaid, together with a cash
      adjustment in respect of any fraction of a share of Common Stock as provided
      in
      Section 6(e). Such conversion shall be deemed to have been made as of the
      date of such notice, compliance and surrender of the shares of Series G
      Preferred Stock to be converted, and the person or persons entitled to receive
      the Common Stock deliverable upon conversion of such Series G Preferred Stock
      shall be treated for all purposes as the record holder or holders of such Common
      Stock on such date.

    (d) Adjustment
      of Conversion Price.
      The
      conversion price at which a share of Series G Preferred Stock is convertible
      into Common Stock shall be subject to adjustment from time to time as
      follows:

    

    (i) Stock
      Dividends, Subdivisions, Reclassifications or Combinations.
      If this
      Corporation shall after the date of the filing of this Statement of Designation:
      

    

    (1) declare
      a
      dividend or make a distribution on its Common Stock in shares of its Common
      Stock,

    

    (2) subdivide
      or reclassify the outstanding shares of Common Stock into a greater number
      of
      shares, or

    

    (3) combine
      or reclassify the outstanding Common Stock into a smaller number of
      shares,

    

    the
      conversion price at which a share of Series G Preferred Stock is convertible
      into Common Stock in effect at the time of the record date for such dividend
      or
      distribution or the effective date of such subdivision, combination or
      reclassification shall be proportionately adjusted so that the holder of any
      shares of Series G Preferred Stock surrendered for conversion after such date
      shall be entitled to receive the number of shares of Common Stock that such
      holder would have owned or been entitled to receive had such shares been
      converted immediately prior to such date. For example, (i) in the event the
      outstanding shares of Common Stock shall be subdivided (by stock split, or
      otherwise) into a greater number of shares of Common Stock, the Conversion
      Price
      for the Series G Preferred Stock then in effect shall, concurrently with the
      effectiveness of such subdivision, be proportionately decreased, and (ii) in
      the
      event the outstanding shares of Common Stock shall be combined or consolidated,
      by reclassification or otherwise, into a lesser number of shares of Common
      Stock, the Conversion Price for the Series G Preferred Stock then in effect
      shall, concurrently with the effectiveness of such combination or consolidation,
      be proportionately increased. Successive adjustments in the conversion price
      for
      the Series G Preferred Stock shall be made whenever any events specified above
      shall occur.

    

    (ii) Adjustment
      for Recapitalization, Reclassification or Substitution.
      If
      Common Stock issuable upon the conversion of shares of the outstanding Series
      G
      Preferred Stock is changed into the same or a different number of shares of
      any
      class or classes of stock, whether by recapitalization, reclassification or
      otherwise (other than a subdivision or combination of shares or stock dividend
      otherwise provided for in this Section 6(d)), then and in such event each holder
      of shares of Preferred Stock shall have the right thereafter, upon conversion,
      to receive the kind and amount of stock and other securities and property
      receivable upon such reorganization or other change in an amount equal to the
      amount that such holder would have been entitled to had it immediately prior
      to
      such recapitalization, reclassification or other change converted such shares,
      but only to the extent such shares are actually converted, all subject to
      further adjustments provided herein. As a part of such recapitalization,
      reclassification or substitution, provision shall be made by the Company so
      that
      such holder shall thereafter be entitled to receive such stock, securities
      and
      property.

    

    
      
         

      

      
        -7-

        
          

        

      

      
         

      

    

    (iii) Certificate
      of Adjustment.
      In any
      case of an adjustment or readjustment of the conversion price for the Series
      G
      Preferred Stock or the number of shares of Common Stock or other securities
      issuable upon conversion, the Company shall promptly compute such adjustment
      or
      readjustment in accordance with the provisions hereof and its chief financial
      officer shall prepare a certificate showing such adjustment or readjustment,
      and
      shall mail such certificate, by first class mail, postage prepaid, to the holder
      at the holder's address as shown in the Company's books. The certificate shall
      set forth such adjustment or readjustment, showing in detail the facts upon
      which such adjustment or readjustment is based, including a statement
      of:

    

    (1) such
      adjustments and readjustments,

    

    (2) the
      conversion price for the Series G Preferred Stock then in effect,
      and

    

    (3) the
      type
      and amount, if any, of other property which at the time would be received upon
      conversion of such shares.

    

    (e) Fractional
      Shares.
      No
      fractional shares of Common Stock shall be issued upon conversion of the
      outstanding Series G Preferred Stock. If more than one share of Series G
      Preferred Stock shall be surrendered for conversion at any one time by the
      same
      holder, the number of full shares of Common Stock issuable upon conversion
      thereof shall be computed on the basis of the aggregate number of shares of
      Preferred Stock so surrendered. Any portion of the outstanding Series G
      Preferred Stock surrendered for conversion which would otherwise result in
      a
      fractional share of Common Stock shall be redeemed for cash in an amount equal
      to the product of such fraction multiplied the market
      price per share of Common Stock (as determined by the Board of Directors or
      in
      any manner prescribed by the Board of Directors, which, so long as the Common
      Stock is quoted on The NASDAQ Stock Market, shall be the closing price for
      such
      stock (or the average of the reported closing bid and asked prices, if no sales
      were reported that day) as quoted on such exchange or system on the date of
      determination, as reported in the Wall
      Street Journal,
      or so
      long as the Common Stock is traded on the over-the-counter market, shall be
      the
      closing sale price as reported by such system at the close of business on the
      day of conversion (or the average of the reported closing bid and asked prices,
      if no sales were reported that day)). 

    

    (f) Reservation
      of Shares; Etc.
      The
      Company shall at all times reserve and keep available, free from preemptive
      rights out of its authorized and unissued stock, solely for the purpose of
      effecting the conversion of the Series G Preferred Stock, such number of shares
      of its Common Stock as shall from time to time be sufficient to effect the
      conversion of all shares of Series G Preferred Stock from time to time
      outstanding. If at any relevant time the number of authorized but unissued
      shares of Common Stock shall not be sufficient to effect the conversion of
      all
      the then outstanding shares of Series G Preferred Stock, the Company will use
      its reasonable efforts to forthwith take such corporate action as may be
      necessary to increase its authorized but unissued shares of Common Stock for
      issuance on conversion of such Series G Preferred Stock to such number of shares
      as shall be sufficient for such purposes. In the event the Company does not
      have, after taking into account all shares reserved for outstanding warrants,
      options other securities convertible into Common Stock, sufficient authorized
      but unissued shares of Common Stock, to allow for conversion of some or all
      of
      its shares of Series G Preferred Stock, the holders of such shares of Series
      G
      Preferred Stock shall not be entitled to convert such shares to Common Stock
      until such time as the Company has sufficient authorized but unissued shares
      of
      Common Stock to allow for conversion.

    (g) Prior
      Notice of Certain Events.
      In
      case:

    

    (i) the
      Company shall (1) declare any dividend (or any other distribution) on its
      Common Stock, other than (A) a dividend payable in shares of Common Stock
      or (B) a dividend payable in cash out of its retained earnings other than
      any special or nonrecurring or other extraordinary dividend or (2) declare
      or authorize a redemption or repurchase of the then-outstanding shares of Common
      Stock; or

    

    (ii) the
      Company shall authorize the granting to all holders of Common Stock of rights
      or
      warrants to subscribe for or purchase any shares of stock of any class or series
      or of any other rights, or warrants; or

    

    (iii) of
      any
      reclassification of Common Stock (other than a subdivision or combination of
      the
      outstanding Common Stock, or a change in par value, or from par value to no
      par
      value; or from no par value to par value), or of any consolidation or merger
      to
      which the Company is a party and for which approval of any stockholders of
      the
      Company shall be required, or of the sale or transfer of all or substantially
      all of the assets of the Company or of any compulsory share exchange whereby
      the
      Common Stock is converted into other securities, cash or other property;
      or

    

    (iv) of
      the
      voluntary or involuntary dissolution, liquidation or winding up of the
      Company;

    

    then
      the
      Company shall cause to be mailed to the holders of record of the Series G
      Preferred Stock, at their last addresses as they shall appear upon the stock
      transfer books of the Company, at least fifteen days prior to the later of
      the
      applicable record or effective date hereinafter specified, a notice stating
      (x) the date on which a record (if any) is to be taken for the purpose of
      such dividend, distribution, redemption, repurchase, rights or warrants or,
      if a
      record is not to be taken, the date as of which the holders of Common Stock
      of
      record to be entitled to such dividend, distribution, redemption, rights or
      warrants are to be determined or (y) the date on which such
      reclassification, consolidation, merger, sale, transfer, share exchange,
      dissolution, liquidation or winding up is expected to become effective, and
      the
      date as of which it is expected that holders of Common Stock of record shall
      be
      entitled to exchange their shares of Common Stock for securities, cash or other
      property deliverable upon such reclassification, consolidation, merger, sale,
      transfer, share exchange, dissolution, liquidation or winding up (but no failure
      to mail such notice or any defect therein or in the mailing thereof shall affect
      the validity of the corporate action required to be specified in such
      notice).

    7. Redemption.

    

    (a) Optional
      Redemption.
      The
      shares of Series G Preferred Stock may be redeemed at the option of the Company,
      to the extent it has funds legally available for such redemption, at any time,
      in whole or in part at a redemption price per share, payable in cash, equal
      to
      $5.00 (as appropriately adjusted for stock splits, stock dividends,
      combinations, recapitalizations and the like with respect to the Series G
      Preferred Stock) plus an amount equal to all accumulated and unpaid cash
      dividends thereon to the date of such redemption (the "Redemption
      Price"),
      whether or not declared.

    

    In
      the
      case of redemption of less than all of the then outstanding shares of Series
      G
      Preferred Stock, the Company shall effect such redemption pro rata.
      Notwithstanding the foregoing, the Company shall not redeem less than all of
      the
      shares of the Series G Preferred Stock at any time outstanding until all
      dividends accumulated and in arrears upon all shares of Series G Preferred
      Stock
      then outstanding for all dividend periods ending prior to the date of redemption
      been paid.

    

    (b) Redemption
      Procedure.
      With
      respect to any redemption of shares of Series G Preferred Stock provided for
      in
      this Section 7, a notice of redemption of shares of Series G Preferred
      Stock (the "Redemption
      Notice")
      shall
      be given by first-class mail, postage prepaid, mailed at least 30 calendar
      days
      prior to the specified redemption date to each holder of the shares of Series
      G
      Preferred Stock to be redeemed, at such holder's address as the same appears
      on
      the register of the Company for the Series G Preferred Stock. Each Redemption
      Notice shall state and include (i) the Redemption Date, (ii) a
      statement either (A) that all of the holder's shares of Series G Preferred
      Stock are being redeemed or (B) the number of such shares to be redeemed
      from the holder (which number will be calculated based on the holder's pro
      rata
      ownership percentage of then outstanding shares of Series G Preferred Stock),
      (iii) the Redemption Price per share, and (iv) the place or places
      where certificates for such shares are to be surrendered for payment of the
      Redemption Price.

    

    (c) Any
      Redemption Notice that is mailed as herein provided shall be conclusively
      presumed to have been duly given, whether or not the holder of the shares of
      Series G Preferred Stock receives such notice; and failure to give such notice
      by mail, or any defect in such notice, to the holders of any shares designated
      for redemption shall not affect the validity of the proceedings for the
      redemption of any other shares of Series G Preferred Stock.

    

    (d) On
      or
      after the Redemption Date as stated in the Redemption Notice, the holders of
      shares of Series G Preferred Stock which have been called for redemption shall
      surrender certificates representing such shares to the Company at its principal
      place of business or as otherwise stated in the Redemption Notice, and thereupon
      the redemption price of such shares shall be paid by the Company in the manner
      specified in the Redemption Notice to the person whose name appears on such
      certificate or certificates as the owner thereof. If less than all the shares
      represented by any such surrendered certificate are redeemed, a new certificate
      shall be issued representing the unredeemed shares. In lieu of issuing any
      fractional interest in a share of Series G Preferred Stock that would otherwise
      be deliverable upon the redemption of less than all shares of Series G Preferred
      Stock, the Company shall pay to the holder of such share an amount in cash
      based
      upon the Redemption Price plus accumulated dividends.

    

    
      
         

      

      
        -10-

        
          

        

      

      
         

      

    

    (e) Notice
      having been given as aforesaid, if, on the date fixed for redemption, funds
      necessary for the redemption shall be available therefor and shall have been
      deposited with a bank or trust company with irrevocable instructions and
      authority to pay the Redemption Price to the holders of the Series G Preferred
      Stock, then, notwithstanding that the certificates representing any shares
      so
      called for redemption shall not have been surrendered, dividends with respect
      to
      the shares so called shall cease to accumulate after the date fixed for
      redemption, such shares shall no longer be deemed outstanding, the holders
      thereof shall cease to be stockholders of the Company, and all rights whatsoever
      with respect to the shares so called for redemption (except the right of the
      holders to receive the Redemption Price without interest upon surrender of
      their
      certificates therefor) shall terminate. If funds legally available for such
      purpose are not sufficient for redemption of the Series G Preferred Stock which
      were to be redeemed, then Section 8 shall apply and the certificates
      representing shares not redeemed pursuant to Section 8 shall be deemed not
      to be surrendered, such shares shall remain outstanding, the right of the holder
      to receive payment of the Redemption Price for such shares shall terminate,
      and
      the right of holders of Series G Preferred Stock thereafter shall continue
      to be
      only those of a holder of shares of the Series G Preferred Stock.

    

    8. Partial
      Payments.
      Upon an
      optional redemption by the Company, if at any time the Company does not pay
      amounts sufficient to redeem all shares of Series G Preferred Stock, then such
      funds which are paid shall be applied to redeem such shares of Series G
      Preferred Stock pro rata.

    

    9. Shares
      to Be Retired.
      All
      shares of Series G Preferred Stock which shall have been issued and reacquired
      in any manner by the Company shall be restored to the status of authorized
      but
      unissued shares of preferred stock of the Company, without designation as to
      class or series.

    

    10. Voting
      Rights.
      

    

    (a) Subject
      to Section 10(b) below, the shares of Series G Preferred Stock shall not entitle
      the holder thereof to voting rights. The shares of Common Stock issuable upon
      conversion of the Series G Preferred Stock shall entitle the holder thereof
      to
      all voting rights provided to the Common Stock generally as a class under the
      Company's articles of incorporation or by law.

    

    (b) Notwithstanding
      the foregoing, so long as any shares of Series G Preferred Stock are
      outstanding, the affirmative vote of at least a majority of the votes entitled
      to be cast by the holders of the Series G Preferred Stock (each such share
      being
      entitled to one vote), voting separately as a class, at the time outstanding,
      given in person or by proxy, either in writing without a meeting or by vote
      at
      any meeting called for the purpose shall be necessary for effecting or
      validating:

    

    (i) Any
      amendment, alteration or repeal of any of the provisions of the articles of
      incorporation or bylaws of the Company or this Statement of Designation that
      adversely affects the voting powers (as limited herein to those provided by
      Section 10(b)(i)-(iii)), rights or preferences of the holders of the Series
      G
      Preferred Stock; provided,
      however,
      that
      the amendment of the provisions of the articles of incorporation of the Company
      so as to authorize or create or to increase the authorized amount of any Parity
      Stock or any Junior Stock, (a) shall not be deemed to adversely affect the
      voting powers, rights or preferences of the holders of Series G Preferred Stock
      and (b) shall not in any case require a separate vote of the holders of
      Series G Preferred Stock; or 

    

    
      
         

      

      
        -11-

        
          

        

      

      
         

      

    

    (ii) A
      share
      exchange that affects the Series G Preferred Stock, a consolidation with or
      merger of the Corporation into another entity, or a consolidation with or merger
      of another entity into the Corporation, or the voluntary sale, lease,
      conveyance, exchange, or transfer (for cash, shares of stock, securities, or
