          (xi) Any Event of Default on the  Convertible  Debentures  (the "Prior

               $565,000  and  $1,475,000,  respectively.  Further,  an  Event of
               Default on this Debenture shall constitute an Event of Default on
               the Prior Debentures.

     (b)  During the time that any portion of this Debenture is outstanding,  if
          any Event of Default has occurred,  the full principal  amount of this
          Debenture,  together  with interest and other amounts owing in respect
          thereof,  to the date of  acceleration  shall  become at the  Holder's
          election,  immediately due and payable in cash, provided however,  the
          Holder may request (but shall have no obligation  to request)  payment
          of such  amounts in Common  Stock of the  Obligor.  In addition to any
          other  remedies,  the  Holder  shall  have  the  right  (but  not  the
          obligation)  to convert this  Debenture at any time after (x) an Event
          of  Default  or (y) the  Maturity  Date at the  Conversion  Price then
          in-effect.  The Holder need not provide and the Obligor  hereby waives
          any presentment,  demand, protest or other notice of any kind, and the
          Holder may  immediately  and without  expiration  of any grace  period
          enforce any and all of its rights and remedies hereunder and all other
          remedies available to it under applicable law. Such declaration may be
          rescinded  and  annulled  by  Holder  at any  time  prior  to  payment
          hereunder. No such rescission or annulment shall affect any subsequent
          Event of Default or impair any right consequent thereon. Upon an Event
          of Default,  notwithstanding  any other provision of this Debenture or
          any  Transaction  Document,  the Holder  shall have no  obligation  to
          comply with or adhere to any limitations, if any, on the conversion of
          this Debenture or the sale of the Underlying Shares.

         Section 3.        Conversion.

     (a)  (i) Conversion at Option of Holder.

          (A)  This Debenture  shall be convertible  into shares of Common Stock
               at the option of the Holder,  in whole or in part at any time and
               from time to time,  after the Original  Issue Date (as defined in
               Section 4) (subject to the limitations on conversion set forth in
               Section  3(a)(ii)  hereof).  The number of shares of Common Stock
               issuable  upon a conversion  hereunder  equals the sum of (i) the
               quotient obtained by dividing (x) the outstanding  amount of this
               Debenture to be converted by (y) the Conversion Price (as defined
               in Section  3(c)(i)).  The Obligor  shall  deliver  Common  Stock
               certificates  to the Holder prior to the Fifth (5th)  Trading Day
               after a Conversion Date.

          (B)  Notwithstanding  anything to the contrary contained herein, if on
               any Conversion  Date: (1) the number of shares of Common Stock at
               the time authorized, unissued and unreserved for all purposes, or
               held as treasury  stock,  is  insufficient  to pay  principal and
               interest  hereunder  in shares of Common  Stock;  (2) the  Common
               Stock is not  listed or  quoted  for  trading  on the OTC or on a
               Subsequent  Market;  (3) the Obligor has failed to timely satisfy
               its  conversion;  or (4) the  issuance  of such  shares of Common
               Stock would result in a violation of Section  3(a)(ii),  then, at
               the option of the  Holder,  the  Obligor,  in lieu of  delivering
               shares of Common  Stock  pursuant  to Section  3(a)(i)(A),  shall
               deliver,  within  three  (3)  Trading  Days  of  each  applicable
               Conversion  Date,  an amount in cash equal to the  product of the
               outstanding  principal  amount to be converted  plus any interest
               due therein divided by the Conversion Price and multiplied by the
               highest  closing  price of the stock from date of the  conversion
               notice till the date that such cash payment is made.

               Further,  if the Obligor shall not have delivered any cash due in
               respect of conversion of this Debenture or as payment of interest
               thereon by the fifth (5th) Trading Day after the Conversion Date,
               the Holder may, by notice to the Obligor,  require the Obligor to
               issue shares of Common  Stock  pursuant to Section  3(c),  except
               that for such purpose the  Conversion  Price  applicable  thereto
               shall be the  lesser of the  Conversion  Price on the  Conversion
               Date and the Conversion  Price on the date of such Holder demand.
               Any  such  shares  will  be  subject  to the  provisions  of this
               Section.

          (C)  The Holder shall effect  conversions by delivering to the Obligor
               a completed  notice in the form  attached  hereto as Exhibit A (a
               "Conversion  Notice").  The date on which a Conversion  Notice is
               delivered  is  the  "Conversion   Date."  Unless  the  Holder  is
               converting the entire  principal  amount  outstanding  under this
               Debenture,  the Holder is not  required to  physically  surrender
               this  Debenture  to the  Obligor in order to effect  conversions.
               Conversions  hereunder  shall  have the  effect of  lowering  the
               outstanding  principal  amount of this Debenture plus all accrued
               and unpaid interest  thereon in an amount equal to the applicable
               conversion.  The Holder and the Obligor  shall  maintain  records
               showing  the  principal  amount  converted  and the  date of such
               conversions.  In the event of any  dispute  or  discrepancy,  the
               records of the Holder shall be controlling and  determinative  in
               the absence of manifest error.

                  (ii) Certain Conversion Restrictions.

          (A)  A Holder may not  convert  this  Debenture  or receive  shares of
               Common Stock as payment of interest  hereunder to the extent such
               conversion  or receipt of such  interest  payment would result in
               the Holder,  together  with any affiliate  thereof,  beneficially
               owning (as  determined  in  accordance  with Section 13(d) of the
               Exchange Act and the rules  promulgated  thereunder) in excess of
               4.9% of the then issued and  outstanding  shares of Common Stock,
               including  shares  issuable  upon  conversion  of, and payment of
               interest on, this Debenture held by such Holder after application
               of this Section. Since the Holder will not be obligated to report
               to the Obligor  the number of shares of Common  Stock it may hold
               at the time of a conversion  hereunder,  unless the conversion at
               issue would  result in the  issuance of shares of Common Stock in
               excess of 4.9% of the then  outstanding  shares  of Common  Stock
               without  regard to any  other  shares  which may be  beneficially
               owned by the Holder or an  affiliate  thereof,  the Holder  shall
               have the  authority  and  obligation  to  determine  whether  the
               restriction  contained in this Section will limit any  particular
               conversion hereunder and to the extent that the Holder determines
               that  the  limitation  contained  in this  Section  applies,  the
               determination  of which portion of the  principal  amount of this
               Debenture  is  convertible  shall  be  the   responsibility   and
               obligation  of  the  Holder.   If  the  Holder  has  delivered  a
               Conversion  Notice for a principal amount of this Debenture that,
               without  regard  to any  other  shares  that  the  Holder  or its
               affiliates may beneficially  own, would result in the issuance in
               excess of the  permitted  amount  hereunder,  the  Obligor  shall
               notify the Holder of this fact and shall honor the conversion for
               the maximum  principal  amount  permitted to be converted on such
               Conversion  Date in  accordance  with the  periods  described  in
               Section  3(a)(i)(A)  and,  at the  option of the  Holder,  either
               retain any principal  amount tendered for conversion in excess of
               the permitted amount  hereunder for future  conversions or return
               such excess  principal  amount to the Holder.  The  provisions of
               this Section may be waived by a Holder (but only as to itself and
               not to any other  Holder) upon not less than 65 days prior notice
               to the Obligor.  Other  Holders  shall be  unaffected by any such
               waiver.

     (b)  (i)  Nothing  herein  shall  limit a Holder's  right to pursue  actual
          damages or declare  an Event of Default  pursuant  to Section 2 herein
          for the Obligor 's failure to deliver certificates representing shares
          of Common Stock upon conversion within the period specified herein and
          such Holder shall have the right to pursue all  remedies  available to
          it at law or in  equity  including,  without  limitation,  a decree of
          specific  performance  and/or injunctive  relief, in each case without
          the need to post a bond or provide other security. The exercise of any
          such rights  shall not  prohibit  the Holder  from  seeking to enforce
          damages pursuant to any other Section hereof or under applicable law.

          (ii) In addition to any other rights  available to the Holder,  if the
               Obligor  fails to  deliver  to the  Holder  such  certificate  or
               certificates  pursuant to Section 3(a)(i)(A) by the fifth Trading
               Day after the  Conversion  Date,  and if after such  fifth  (5th)
               Trading Day the Holder  purchases (in an open market  transaction
               or otherwise)  Common Stock to deliver in  satisfaction of a sale
               by  such  Holder  of  the  Underlying  Shares  which  the  Holder
               anticipated receiving upon such conversion (a "Buy-In"), then the
               Obligor  shall (A) pay in cash to the Holder (in  addition to any
               remedies  available  to or elected by the  Holder)  the amount by
               which (x) the Holder's total purchase price (including  brokerage
               commissions,  if any) for the Common Stock so  purchased  exceeds
               (y) the product of (1) the  aggregate  number of shares of Common
               Stock that such Holder anticipated  receiving from the conversion
               at issue  multiplied  by (2) the market price of the Common Stock
               at the time of the sale giving rise to such  purchase  obligation
               and (B) at the option of the Holder,  either  reissue a Debenture
               in the  principal  amount  equal to the  principal  amount of the
               attempted  conversion  or  deliver  to the  Holder  the number of
               shares of Common  Stock  that  would  have  been  issued  had the
               Obligor  timely  complied  with its delivery  requirements  under
               Section  3(a)(i)(A).  For example, if the Holder purchases Common
               Stock having a total  purchase price of $11,000 to cover a Buy-In
               with  respect  to an  attempted  conversion  of  Debentures  with
               respect to which the market price of the Underlying Shares on the
               date of conversion was a total of $10,000 under clause (A) of the
               immediately preceding sentence,  the Obligor shall be required to
               pay the Holder  $1,000.  The Holder  shall  provide  the  Obligor
               written notice  indicating  the amounts  payable to the Holder in
               respect of the Buy-In.

     (c)  (i) The  conversion  price in effect on any  Conversion  Date shall be
          equal to the lesser of (a) the Closing  Bid Price of the Common  Stock
          on the  date the  notice  of the  approval  of this  Debenture  by the
          shareholders  of the Obligor is mailed to the  Obligor's  shareholders
          (the "Fixed Conversion  Price") or (b) the average of the three lowest
          closing  market  prices of the  Company's  Common Stock for the thirty
          days preceding  conversion (the "Market Conversion Price").  The Fixed
          Conversion  Price and the  Market  Conversion  Price are  collectively
          referred to as the  "Conversion  Price." The  Conversion  Price may be
          adjusted pursuant to the other terms of this Debenture.

          (ii) If the Obligor,  at any time while this Debenture is outstanding,
               shall (a) pay a stock  dividend or otherwise  make a distribution
               or  distributions  on  shares  of its  Common  Stock or any other
               equity  or  equity  equivalent  securities  payable  in shares of
               Common Stock,  (b) subdivide  outstanding  shares of Common Stock
               into a larger number of shares,  (c) combine (including by way of
               reverse  stock split)  outstanding  shares of Common Stock into a
               smaller  number of shares,  or (d) issue by  reclassification  of
               shares of the Common  Stock any  shares of  capital  stock of the
               Obligor,  then the  Conversion  Price  shall be  multiplied  by a
               fraction of which the numerator  shall be the number of shares of
               Common Stock  (excluding  treasury  shares,  if any)  outstanding
               before  such  event  and of which  the  denominator  shall be the
               number of shares of Common  Stock  outstanding  after such event.
               Any  adjustment  made  pursuant  to  this  Section  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 re-classification.

          (iii) If the Obligor, at any time while this Debenture is outstanding,
               shall issue rights,  options or warrants to all holders of Common
               Stock (and not to the Holder)  entitling them to subscribe for or
               purchase  shares of Common  Stock at a price per share  less than
               the Fixed Conversion Price, then the Fixed Conversion Price shall
               be multiplied by a fraction,  of which the  denominator  shall be
               the  number of shares of the  Common  Stock  (excluding  treasury
               shares,  if any)  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
               (excluding  treasury  shares,  if any) 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  would  purchase  at  Fixed  Conversion  Price.  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. However, upon the expiration of
               any such  right,  option or  warrant  to  purchase  shares of the
               Common Stock the issuance of which  resulted in an  adjustment in
               the Fixed Conversion Price pursuant to this Section,  if any such
               right,  option or  warrant  shall  expire and shall not have been
               exercised, the Fixed Conversion Price shall immediately upon such
               expiration be  recomputed  and  effective  immediately  upon such
               expiration  be  increased  to the price  which it would have been
               (but  reflecting any other  adjustments  in the Fixed  Conversion
               Price made  pursuant to the  provisions of this Section after the
               issuance of such rights or warrants)  had the  adjustment  of the
               Fixed  Conversion  Price made upon the  issuance of such  rights,
               options  or  warrants  been  made on the  basis of  offering  for
               subscription or purchase only that number of shares of the Common
               Stock  actually  purchased  upon  the  exercise  of such  rights,
               options or warrants actually exercised.

          (iv) If the Obligor or any subsidiary  thereof,  as  applicable,  with
               respect to Common Stock  Equivalents (as defined  below),  at any
               time while this Debenture is  outstanding,  shall issue shares of
               Common Stock or rights, warrants,  options or other securities or
               debt that are  convertible  into or  exchangeable  for  shares of
               Common Stock ("Common Stock Equivalents") entitling any Person to
               acquire  shares of Common  Stock,  at a price per share less than
               the Fixed  Conversion Price (if the holder of the Common Stock or
               Common Stock  Equivalent 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 is issued in
               connection  with such issuance,  be entitled to receive shares of
               Common  Stock at a price per  share  which is less than the Fixed
               Conversion  Price, such issuance shall be deemed to have occurred
               for less  than the Fixed  Conversion  Price),  then,  at the sole
               option  of the  Holder,  the  Fixed  Conversion  Price  shall  be
               adjusted to mirror the conversion, exchange or purchase price for
               such Common  Stock or Common  Stock  Equivalents  (including  any
               reset provisions thereof) at issue. Such adjustment shall be made
               whenever  such  Common  Stock or  Common  Stock  Equivalents  are
               issued. The Obligor shall notify the Holder in writing,  no later
               than one (1)  business day  following  the issuance of any Common
               Stock  or  Common  Stock  Equivalent  subject  to  this  Section,
               indicating   therein  the  applicable   issuance   price,  or  of
               applicable  reset price,  exchange  price,  conversion  price and
               other pricing  terms.  No adjustment  under this Section shall be
               made as a  result  of  issuances  and  exercises  of  options  to
               purchase shares of Common Stock issued for compensatory  purposes
               pursuant to any of the Obligor's  stock option or stock  purchase
               plans.

          (v)  If the Obligor,  at any time while this Debenture is outstanding,
               shall  distribute  to all holders of Common Stock (and not to the
               Holder)  evidences  of its  indebtedness  or  assets or rights or
               warrants to subscribe for or purchase any security,  then in each
               such  case the Fixed  Conversion  Price at which  this  Debenture
               shall   thereafter   be   convertible   shall  be  determined  by
               multiplying  the Fixed  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 Closing Bid Price  determined as of the
               record date mentioned  above, and of which the numerator shall be
               such  Closing  Bid Price on such  record  date less the then fair
               market value at such record date of the portion of such assets or
               evidence  of  indebtedness  so  distributed   applicable  to  one
               outstanding  share of the Common Stock as determined by the Board
               of Directors in good faith. In either case the adjustments  shall
               be described in a statement provided to the Holder of 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.

          (vi) In  case  of any  reclassification  of the  Common  Stock  or any
               compulsory  share exchange  pursuant to which the Common Stock is
               converted  into other  securities,  cash or property,  the Holder
               shall have the right  thereafter  to, at its option,  (A) convert
               the then outstanding principal amount,  together with all accrued
               but unpaid interest and any other amounts then owing hereunder in
               respect  of this  Debenture  into the  shares  of stock and other
               securities,  cash and  property  receivable  upon or deemed to be
               held   by   holders   of  the   Common   Stock   following   such
               reclassification  or  share  exchange,  and  the  Holder  of this
               Debenture  shall be  entitled  upon such  event to  receive  such
               amount  of  securities,  cash or  property  as the  shares of the
               Common  Stock of the  Obligor  into  which  the then  outstanding
               principal  amount,  together with all accrued but unpaid interest
               and any other  amounts  then owing  hereunder  in respect of this
               Debenture  could have been  converted  immediately  prior to such
               reclassification  or share exchange would have been entitled,  or
               (B)  require  the  Obligor  to prepay the  outstanding  principal
               amount of this Debenture, plus all interest and other amounts due
               and payable thereon. The entire prepayment price shall be paid in
               cash.   This  provision   shall  similarly  apply  to  successive
               reclassifications or share exchanges.

          (vii) The Obligor shall  maintain a share reserve of not less than 50%
               of the shares of Common Stock  issuable  upon  conversion of this
               Debenture;  and within  three (3)  Business  Days  following  the
               receipt by the  Obligor of a Holder's  notice  that such  minimum
               number of Underlying Shares is not so reserved, the Obligor shall
               promptly reserve a sufficient number of shares of Common Stock to
               comply with such requirement.

          (viii) All  calculations  under this  Section 3 shall be rounded up to
               the nearest $0.001 of a share.

          (ix) Whenever the Conversion is adjusted pursuant to Section 3 hereof,
               the Obligor shall  promptly  mail to the Holder a notice  setting
               forth the  Conversion  Price  after such  adjustment  and setting
               forth a brief statement of the facts requiring such adjustment.

          (x)  If (A) the  Obligor  shall  declare  a  dividend  (or  any  other
               distribution)  on the Common Stock; (B) the Obligor shall declare
               a special  nonrecurring  cash  dividend on or a redemption of the
               Common Stock; (C) the Obligor shall authorize the granting to all
               holders of the Common Stock  rights or warrants to subscribe  for
               or  purchase  any shares of capital  stock of any class or of any
               rights; (D) the approval of any stockholders of the Obligor shall
               be required in connection with any reclassification of the Common
               Stock,  any  consolidation  or merger to which the  Obligor  is a
               party,  any sale or transfer of all or  substantially  all of the
               assets of the Obligor,  of any compulsory  share exchange whereby
               the Common  Stock is  converted  into other  securities,  cash or
               property;  or (E) the Obligor  shall  authorize  the voluntary or
               involuntary dissolution, liquidation or winding up of the affairs
               of the Obligor; then, in each case, the Obligor shall cause to be
               filed at each  office or agency  maintained  for the  purpose  of
               conversion of this Debenture, and shall cause to be mailed to the
               Holder  at its last  address  as it shall  appear  upon the stock
               books of the Obligor, at least twenty (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 mail such notice or any
               defect  therein or in the  mailing  thereof  shall not affect the
               validity of the corporate action required to be specified in such
               notice.  The Holder is entitled to convert this Debenture  during
               the 20-day calendar period  commencing the date of such notice to
               the effective date of the event triggering such notice.

          (xi) In case of any (1) merger or  consolidation of the Obligor or any
               subsidiary  of the Obligor  with or into another  Person,  or (2)
               sale by the Obligor or any subsidiary of the Obligor of more than
               one-half  of the  assets  of the  Obligor  in one or a series  of
               related  transactions,  a  Holder  shall  have  the  right to (A)
               exercise any rights under Section 2(b), (B) convert the aggregate
               amount of this  Debenture  then  outstanding  into the  shares of
               stock and other securities,  cash and property receivable upon or
               deemed to be held by  holders  of  Common  Stock  following  such
               merger,  consolidation or sale, and such Holder shall be entitled
               upon such  event or  series of  related  events to  receive  such
               amount of  securities,  cash and property as the shares of Common
               Stock  into  which  such  aggregate   principal  amount  of  this
               Debenture  could have been  converted  immediately  prior to such
               merger,  consolidation or sales would have been entitled,  or (C)
               in the case of a merger or  consolidation,  require the surviving
               entity  to issue to the  Holder a  convertible  Debenture  with a
               principal amount equal to the aggregate  principal amount of this
               Debenture  then held by such Holder,  plus all accrued and unpaid
               interest and other amounts owing thereon, which such newly issued
               convertible  Debenture shall have terms identical (including with
               respect to conversion) to the terms of this Debenture,  and shall
               be entitled to all of the rights and  privileges of the Holder of
               this  Debenture set forth herein and the  agreements  pursuant to
               which this Debentures were issued. In the case of clause (C), the
               conversion  price  applicable  for the  newly  issued  shares  of
               convertible  preferred stock or convertible  Debentures  shall be
               based upon the amount of securities,  cash and property that each
               share of Common Stock would receive in such  transaction  and the
               Conversion Price in effect immediately prior to the effectiveness
               or  closing  date for  such  transaction.  The  terms of any such
               merger,  sale or consolidation  shall include such terms so as to
               continue to give the Holder the right to receive the  securities,
               cash and property  set forth in this Section upon any  conversion
               or  redemption   following  such  event.   This  provision  shall
               similarly apply to successive such events.

     (d)  The  Obligor  covenants  that it will at all  times  reserve  and keep
          available out of its  authorized  and unissued  shares of Common Stock
          solely for the purpose of issuance upon  conversion of this  Debenture
          and payment of interest on this  Debenture,  each as herein  provided,
          free from preemptive  rights or any other actual  contingent  purchase
          rights of persons other than the Holder,  not less than such number of
          shares  of the  Common  Stock  as  shall  (subject  to any  additional
          requirements of the Obligor as to reservation of such shares set forth
          in this  Debenture) be issuable  (taking into account the  adjustments
          and restrictions of Sections 2(b) and 3(c)) upon the conversion of the

on a day other  than a  Business  Day,  such  payment  shall be made on the next
succeeding Business Day.

               such  case  or  proceeding  is  entered;  or the  Obligor  or any
               subsidiary  of  the  Obligor   suffers  any  appointment  of  any

               assignment  for the benefit of  creditors;  or the Obligor or any
               subsidiary  of the Obligor shall fail to pay, or shall state that

               indebtedness  now exists or shall  hereafter  be created and such
               default  shall  result  in such  indebtedness  becoming  or being
               declared  due and  payable  prior  to the  date on which it would
               otherwise become due and payable;

          (v)  The Common  Stock  shall cease to be quoted for trading or listed
               for  trading on the Nasdaq OTC  Bulletin  Board  ("OTC"),  Nasdaq
               SmallCap Market, New York Stock Exchange, American Stock Exchange

               shall not again be quoted or listed for  trading  thereon  within

               Commission  (as defined in Section 4), or the  Underlying  Shares
               Registration  Statement shall not have been declared effective by

          (viii) If the  effectiveness  of the  Underlying  Shares  Registration
               Statement  lapses  for any  reason  or the  Holder  shall  not be

          (ix) The  Obligor  shall fail for any reason to deliver  Common  Stock
               certificates  to a Holder  prior to the fifth  (5th)  Trading Day
               after a Conversion  Date or the Obligor shall  provide  notice to
               the Holder, including by way of public announcement, at any time,
               of its intention not to comply with requests for  conversions  of
               this Debenture in accordance with the terms hereof;

          (x)  The  Obligor  shall fail for any reason to deliver the payment in
               cash  pursuant to a Buy-In (as defined  herein)  within three (3)
               days after notice is claimed delivered hereunder; or

          (xi) Any Event of Default on the  Convertible  Debentures  (the "Prior
               Debentures") dated as of April 1, 2005, July 15, 2005 and October
               12,  2005  in  the  original  principal  amounts  of  $2,535,611,
               $565,000  and  $1,475,000,  respectively.  Further,  an  Event of
               Default on this Debenture shall constitute an Event of Default on
               the Prior Debentures.

     (b)  During the time that any portion of this Debenture is outstanding,  if
          any Event of Default has occurred,  the full principal  amount of this
          Debenture,  together  with interest and other amounts owing in respect
          thereof,  to the date of  acceleration  shall  become at the  Holder's
          election,  immediately due and payable in cash, provided however,  the
          Holder may request (but shall have no obligation  to request)  payment
          of such  amounts in Common  Stock of the  Obligor.  In addition to any
          other  remedies,  the  Holder  shall  have  the  right  (but  not  the
          obligation)  to convert this  Debenture at any time after (x) an Event
          of  Default  or (y) the  Maturity  Date at the  Conversion  Price then
          in-effect.  The Holder need not provide and the Obligor  hereby waives
          any presentment,  demand, protest or other notice of any kind, and the
          Holder may  immediately  and without  expiration  of any grace  period
          enforce any and all of its rights and remedies hereunder and all other
          remedies available to it under applicable law. Such declaration may be
          rescinded  and  annulled  by  Holder  at any  time  prior  to  payment
          hereunder. No such rescission or annulment shall affect any subsequent
          Event of Default or impair any right consequent thereon. Upon an Event
          of Default,  notwithstanding  any other provision of this Debenture or
          any  Transaction  Document,  the Holder  shall have no  obligation  to
          comply with or adhere to any limitations, if any, on the conversion of
          this Debenture or the sale of the Underlying Shares.

         Section 3.        Conversion.

         (a) (i) Conversion at Option of Holder.

          (A)  This Debenture  shall be convertible  into shares of Common Stock
               at the option of the Holder,  in whole or in part at any time and
               from time to time,  after the Original  Issue Date (as defined in
               Section 4) (subject to the limitations on conversion set forth in
               Section  3(a)(ii)  hereof).  The number of shares of Common Stock
               issuable  upon a conversion  hereunder  equals the sum of (i) the
               quotient obtained by dividing (x) the outstanding  amount of this
               Debenture to be converted by (y) the Conversion Price (as defined
               in Section  3(c)(i)).  The Obligor  shall  deliver  Common  Stock
               certificates  to the Holder prior to the Fifth (5th)  Trading Day
               after a Conversion Date.

          (B)  Notwithstanding  anything to the contrary contained herein, if on
               any Conversion  Date: (1) the number of shares of Common Stock at
               the time authorized, unissued and unreserved for all purposes, or
               held as treasury  stock,  is  insufficient  to pay  principal and
               interest  hereunder  in shares of Common  Stock;  (2) the  Common
               Stock is not  listed or  quoted  for  trading  on the OTC or on a
               Subsequent  Market;  (3) the Obligor has failed to timely satisfy
               its  conversion;  or (4) the  issuance  of such  shares of Common
               Stock would result in a violation of Section  3(a)(ii),  then, at
               the option of the  Holder,  the  Obligor,  in lieu of  delivering
               shares of Common  Stock  pursuant  to Section  3(a)(i)(A),  shall
               deliver,  within  three  (3)  Trading  Days  of  each  applicable
               Conversion  Date,  an amount in cash equal to the  product of the
               outstanding  principal  amount to be converted  plus any interest
               due therein divided by the Conversion Price and multiplied by the
               highest  closing  price of the stock from date of the  conversion
               notice till the date that such cash payment is made.

               Further,  if the Obligor shall not have delivered any cash due in
               respect of conversion of this Debenture or as payment of interest
               thereon by the fifth (5th) Trading Day after the Conversion Date,
               the Holder may, by notice to the Obligor,  require the Obligor to
               issue shares of Common  Stock  pursuant to Section  3(c),  except
               that for such purpose the  Conversion  Price  applicable  thereto
               shall be the  lesser of the  Conversion  Price on the  Conversion
               Date and the Conversion  Price on the date of such Holder demand.
               Any  such  shares  will  be  subject  to the  provisions  of this
               Section.

          (C)  The Holder shall effect  conversions by delivering to the Obligor
               a completed  notice in the form  attached  hereto as Exhibit A (a
               "Conversion  Notice").  The date on which a Conversion  Notice is
               delivered  is  the  "Conversion   Date."  Unless  the  Holder  is
               converting the entire  principal  amount  outstanding  under this
               Debenture,  the Holder is not  required to  physically  surrender
               this  Debenture  to the  Obligor in order to effect  conversions.
               Conversions  hereunder  shall  have the  effect of  lowering  the
               outstanding  principal  amount of this Debenture plus all accrued
               and unpaid interest  thereon in an amount equal to the applicable
               conversion.  The Holder and the Obligor  shall  maintain  records
               showing  the  principal  amount  converted  and the  date of such
               conversions.  In the event of any  dispute  or  discrepancy,  the
               records of the Holder shall be controlling and  determinative  in
               the absence of manifest error.

                  (ii) Certain Conversion Restrictions.

          (A)  A Holder may not  convert  this  Debenture  or receive  shares of
               Common Stock as payment of interest  hereunder to the extent such
               conversion  or receipt of such  interest  payment would result in
               the Holder,  together  with any affiliate  thereof,  beneficially
               owning (as  determined  in  accordance  with Section 13(d) of the
               Exchange Act and the rules  promulgated  thereunder) in excess of
               4.9% of the then issued and  outstanding  shares of Common Stock,
               including  shares  issuable  upon  conversion  of, and payment of
               interest on, this Debenture held by such Holder after application
               of this Section. Since the Holder will not be obligated to report
               to the Obligor  the number of shares of Common  Stock it may hold
               at the time of a conversion  hereunder,  unless the conversion at
               issue would  result in the  issuance of shares of Common Stock in
               excess of 4.9% of the then  outstanding  shares  of Common  Stock
               without  regard to any  other  shares  which may be  beneficially
               owned by the Holder or an  affiliate  thereof,  the Holder  shall
               have the  authority  and  obligation  to  determine  whether  the
               restriction  contained in this Section will limit any  particular
               conversion hereunder and to the extent that the Holder determines
               that  the  limitation  contained  in this  Section  applies,  the
               determination  of which portion of the  principal  amount of this
               Debenture  is  convertible  shall  be  the   responsibility   and
               obligation  of  the  Holder.   If  the  Holder  has  delivered  a
               Conversion  Notice for a principal amount of this Debenture that,
               without  regard  to any  other  shares  that  the  Holder  or its
               affiliates may beneficially  own, would result in the issuance in
               excess of the  permitted  amount  hereunder,  the  Obligor  shall
               notify the Holder of this fact and shall honor the conversion for
               the maximum  principal  amount  permitted to be converted on such
               Conversion  Date in  accordance  with the  periods  described  in
               Section  3(a)(i)(A)  and,  at the  option of the  Holder,  either
               retain any principal  amount tendered for conversion in excess of
               the permitted amount  hereunder for future  conversions or return
               such excess  principal  amount to the Holder.  The  provisions of
               this Section may be waived by a Holder (but only as to itself and
               not to any other  Holder) upon not less than 65 days prior notice
               to the Obligor.  Other  Holders  shall be  unaffected by any such
               waiver.

     (b)  (i)  Nothing  herein  shall  limit a Holder's  right to pursue  actual
          damages or declare  an Event of Default  pursuant  to Section 2 herein
          for the Obligor 's failure to deliver certificates representing shares
          of Common Stock upon conversion within the period specified herein and
          such Holder shall have the right to pursue all  remedies  available to
          it at law or in  equity  including,  without  limitation,  a decree of
          specific  performance  and/or injunctive  relief, in each case without
          the need to post a bond or provide other security. The exercise of any
          such rights  shall not  prohibit  the Holder  from  seeking to enforce
          damages pursuant to any other Section hereof or under applicable law.

          (ii) In addition to any other rights  available to the Holder,  if the
               Obligor  fails to  deliver  to the  Holder  such  certificate  or
               certificates  pursuant to Section 3(a)(i)(A) by the fifth Trading
               Day after the  Conversion  Date,  and if after such  fifth  (5th)
               Trading Day the Holder  purchases (in an open market  transaction
               or otherwise)  Common Stock to deliver in  satisfaction of a sale
               by  such  Holder  of  the  Underlying  Shares  which  the  Holder
               anticipated receiving upon such conversion (a "Buy-In"), then the
               Obligor  shall (A) pay in cash to the Holder (in  addition to any
               remedies  available  to or elected by the  Holder)  the amount by
               which (x) the Holder's total purchase price (including  brokerage
               commissions,  if any) for the Common Stock so  purchased  exceeds
               (y) the product of (1) the  aggregate  number of shares of Common
               Stock that such Holder anticipated  receiving from the conversion
               at issue  multiplied  by (2) the market price of the Common Stock
               at the time of the sale giving rise to such  purchase  obligation
               and (B) at the option of the Holder,  either  reissue a Debenture
               in the  principal  amount  equal to the  principal  amount of the
               attempted  conversion  or  deliver  to the  Holder  the number of
               shares of Common  Stock  that  would  have  been  issued  had the
               Obligor  timely  complied  with its delivery  requirements  under
               Section  3(a)(i)(A).  For example, if the Holder purchases Common
               Stock having a total  purchase price of $11,000 to cover a Buy-In
               with  respect  to an  attempted  conversion  of  Debentures  with
               respect to which the market price of the Underlying Shares on the
               date of conversion was a total of $10,000 under clause (A) of the
               immediately preceding sentence,  the Obligor shall be required to
               pay the Holder  $1,000.  The Holder  shall  provide  the  Obligor
               written notice  indicating  the amounts  payable to the Holder in
               respect of the Buy-In.

          (c)  (i) The conversion  price in effect on any Conversion  Date shall
               be equal to the lesser of (a) the Closing Bid Price of the Common
               Stock on the date the notice of the approval of this Debenture by
               the  shareholders  of the  Obligor  is  mailed  to the  Obligor's
               shareholders (the "Fixed Conversion Price") or (b) the average of
               the three lowest  closing  market prices of the Company's  Common
               Stock for the  thirty  days  preceding  conversion  (the  "Market
               Conversion  Price").  The Fixed  Conversion  Price and the Market
               Conversion Price are collectively  referred to as the "Conversion
               Price."  The  Conversion  Price may be  adjusted  pursuant to the
               other terms of this Debenture.

          (ii) If the Obligor,  at any time while this Debenture is outstanding,
               shall (a) pay a stock  dividend or otherwise  make a distribution
               or  distributions  on  shares  of its  Common  Stock or any other
               equity  or  equity  equivalent  securities  payable  in shares of
               Common Stock,  (b) subdivide  outstanding  shares of Common Stock
               into a larger number of shares,  (c) combine (including by way of
               reverse  stock split)  outstanding  shares of Common Stock into a
               smaller  number of shares,  or (d) issue by  reclassification  of
               shares of the Common  Stock any  shares of  capital  stock of the
               Obligor,  then the  Conversion  Price  shall be  multiplied  by a
               fraction of which the numerator  shall be the number of shares of
               Common Stock  (excluding  treasury  shares,  if any)  outstanding
               before  such  event  and of which  the  denominator  shall be the
               number of shares of Common  Stock  outstanding  after such event.
               Any  adjustment  made  pursuant  to  this  Section  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 re-classification.

          (iii) If the Obligor, at any time while this Debenture is outstanding,
               shall issue rights,  options or warrants to all holders of Common
               Stock (and not to the Holder)  entitling them to subscribe for or
               purchase  shares of Common  Stock at a price per share  less than
               the Fixed Conversion Price, then the Fixed Conversion Price shall
               be multiplied by a fraction,  of which the  denominator  shall be
               the  number of shares of the  Common  Stock  (excluding  treasury
               shares,  if any)  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
               (excluding  treasury  shares,  if any) 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  would  purchase  at  Fixed  Conversion  Price.  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. However, upon the expiration of
               any such  right,  option or  warrant  to  purchase  shares of the
               Common Stock the issuance of which  resulted in an  adjustment in
               the Fixed Conversion Price pursuant to this Section,  if any such
               right,  option or  warrant  shall  expire and shall not have been
               exercised, the Fixed Conversion Price shall immediately upon such
               expiration be  recomputed  and  effective  immediately  upon such
               expiration  be  increased  to the price  which it would have been
               (but  reflecting any other  adjustments  in the Fixed  Conversion
               Price made  pursuant to the  provisions of this Section after the
               issuance of such rights or warrants)  had the  adjustment  of the
               Fixed  Conversion  Price made upon the  issuance of such  rights,
               options  or  warrants  been  made on the  basis of  offering  for
               subscription or purchase only that number of shares of the Common
               Stock  actually  purchased  upon  the  exercise  of such  rights,
               options or warrants actually exercised.

          (iv) If the Obligor or any subsidiary  thereof,  as  applicable,  with
               respect to Common Stock  Equivalents (as defined  below),  at any
               time while this Debenture is  outstanding,  shall issue shares of
               Common Stock or rights, warrants,  options or other securities or
               debt that are  convertible  into or  exchangeable  for  shares of
               Common Stock ("Common Stock Equivalents") entitling any Person to
               acquire  shares of Common  Stock,  at a price per share less than
               the Fixed  Conversion Price (if the holder of the Common Stock or
               Common Stock  Equivalent 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 is issued in
               connection  with such issuance,  be entitled to receive shares of
               Common  Stock at a price per  share  which is less than the Fixed
               Conversion  Price, such issuance shall be deemed to have occurred
               for less  than the Fixed  Conversion  Price),  then,  at the sole
               option  of the  Holder,  the  Fixed  Conversion  Price  shall  be
               adjusted to mirror the conversion, exchange or purchase price for
               such Common  Stock or Common  Stock  Equivalents  (including  any
               reset provisions thereof) at issue. Such adjustment shall be made
               whenever  such  Common  Stock or  Common  Stock  Equivalents  are
               issued. The Obligor shall notify the Holder in writing,  no later
               than one (1)  business day  following  the issuance of any Common
               Stock  or  Common  Stock  Equivalent  subject  to  this  Section,
               indicating   therein  the  applicable   issuance   price,  or  of
               applicable  reset price,  exchange  price,  conversion  price and
               other pricing  terms.  No adjustment  under this Section shall be
               made as a  result  of  issuances  and  exercises  of  options  to
               purchase shares of Common Stock issued for compensatory  purposes
               pursuant to any of the Obligor's  stock option or stock  purchase
               plans.

          (v)  If the Obligor,  at any time while this Debenture is outstanding,
               shall  distribute  to all holders of Common Stock (and not to the
               Holder)  evidences  of its  indebtedness  or  assets or rights or
               warrants to subscribe for or purchase any security,  then in each
               such  case the Fixed  Conversion  Price at which  this  Debenture
               shall   thereafter   be   convertible   shall  be  determined  by
               multiplying  the Fixed  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 Closing Bid Price  determined as of the
               record date mentioned  above, and of which the numerator shall be
               such  Closing  Bid Price on such  record  date less the then fair
               market value at such record date of the portion of such assets or
               evidence  of  indebtedness  so  distributed   applicable  to  one
               outstanding  share of the Common Stock as determined by the Board
               of Directors in good faith. In either case the adjustments  shall
               be described in a statement provided to the Holder of 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.

          (vi) In  case  of any  reclassification  of the  Common  Stock  or any
               compulsory  share exchange  pursuant to which the Common Stock is
               converted  into other  securities,  cash or property,  the Holder
               shall have the right  thereafter  to, at its option,  (A) convert
               the then outstanding principal amount,  together with all accrued
               but unpaid interest and any other amounts then owing hereunder in
               respect  of this  Debenture  into the  shares  of stock and other
               securities,  cash and  property  receivable  upon or deemed to be
               held   by   holders   of  the   Common   Stock   following   such
               reclassification  or  share  exchange,  and  the  Holder  of this
               Debenture  shall be  entitled  upon such  event to  receive  such
               amount  of  securities,  cash or  property  as the  shares of the
               Common  Stock of the  Obligor  into  which  the then  outstanding
               principal  amount,  together with all accrued but unpaid interest
               and any other  amounts  then owing  hereunder  in respect of this
               Debenture  could have been  converted  immediately  prior to such
               reclassification  or share exchange would have been entitled,  or
               (B)  require  the  Obligor  to prepay the  outstanding  principal
               amount of this Debenture, plus all interest and other amounts due
               and payable thereon. The entire prepayment price shall be paid in
               cash.   This  provision   shall  similarly  apply  to  successive
               reclassifications or share exchanges.

          (vii) The Obligor shall  maintain a share reserve of not less than 50%
               of the shares of Common Stock  issuable  upon  conversion of this
               Debenture;  and within  three (3)  Business  Days  following  the
               receipt by the  Obligor of a Holder's  notice  that such  minimum
               number of Underlying Shares is not so reserved, the Obligor shall
               promptly reserve a sufficient number of shares of Common Stock to
               comply with such requirement.

          (viii) All  calculations  under this  Section 3 shall be rounded up to
               the nearest $0.001 of a share.

          (ix) Whenever the Conversion is adjusted pursuant to Section 3 hereof,
               the Obligor shall  promptly  mail to the Holder a notice  setting
               forth the  Conversion  Price  after such  adjustment  and setting
               forth a brief statement of the facts requiring such adjustment.

          (x)  If (A) the  Obligor  shall  declare  a  dividend  (or  any  other
               distribution)  on the Common Stock; (B) the Obligor shall declare
               a special  nonrecurring  cash  dividend on or a redemption of the
               Common Stock; (C) the Obligor shall authorize the granting to all
               holders of the Common Stock  rights or warrants to subscribe  for
               or  purchase  any shares of capital  stock of any class or of any
               rights; (D) the approval of any stockholders of the Obligor shall
               be required in connection with any reclassification of the Common
               Stock,  any  consolidation  or merger to which the  Obligor  is a
               party,  any sale or transfer of all or  substantially  all of the
               assets of the Obligor,  of any compulsory  share exchange whereby
               the Common  Stock is  converted  into other  securities,  cash or
               property;  or (E) the Obligor  shall  authorize  the voluntary or
               involuntary dissolution, liquidation or winding up of the affairs
               of the Obligor; then, in each case, the Obligor shall cause to be
               filed at each  office or agency  maintained  for the  purpose  of
               conversion of this Debenture, and shall cause to be mailed to the
               Holder  at its last  address  as it shall  appear  upon the stock
               books of the Obligor, at least twenty (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 mail such notice or any
               defect  therein or in the  mailing  thereof  shall not affect the
               validity of the corporate action required to be specified in such
               notice.  The Holder is entitled to convert this Debenture  during
               the 20-day calendar period  commencing the date of such notice to
               the effective date of the event triggering such notice.

          (xi) In case of any (1) merger or  consolidation of the Obligor or any
               subsidiary  of the Obligor  with or into another  Person,  or (2)
               sale by the Obligor or any subsidiary of the Obligor of more than
               one-half  of the  assets  of the  Obligor  in one or a series  of
               related  transactions,  a  Holder  shall  have  the  right to (A)
               exercise any rights under Section 2(b), (B) convert the aggregate
               amount of this  Debenture  then  outstanding  into the  shares of
               stock and other securities,  cash and property receivable upon or
               deemed to be held by  holders  of  Common  Stock  following  such
               merger,  consolidation or sale, and such Holder shall be entitled
               upon such  event or  series of  related  events to  receive  such
               amount of  securities,  cash and property as the shares of Common
               Stock  into  which  such  aggregate   principal  amount  of  this
               Debenture  could have been  converted  immediately  prior to such
               merger,  consolidation or sales would have been entitled,  or (C)
               in the case of a merger or  consolidation,  require the surviving
               entity  to issue to the  Holder a  convertible  Debenture  with a
               principal amount equal to the aggregate  principal amount of this
               Debenture  then held by such Holder,  plus all accrued and unpaid
               interest and other amounts owing thereon, which such newly issued
               convertible  Debenture shall have terms identical (including with
               respect to conversion) to the terms of this Debenture,  and shall
               be entitled to all of the rights and  privileges of the Holder of
               this  Debenture set forth herein and the  agreements  pursuant to
               which this Debentures were issued. In the case of clause (C), the
               conversion  price  applicable  for the  newly  issued  shares  of
               convertible  preferred stock or convertible  Debentures  shall be
               based upon the amount of securities,  cash and property that each
               share of Common Stock would receive in such  transaction  and the
               Conversion Price in effect immediately prior to the effectiveness
               or  closing  date for  such  transaction.  The  terms of any such
               merger,  sale or consolidation  shall include such terms so as to
               continue to give the Holder the right to receive the  securities,
               cash and property  set forth in this Section upon any  conversion
               or  redemption   following  such  event.   This  provision  shall
               similarly apply to successive such events.

     (d)  The  Obligor  covenants  that it will at all  times  reserve  and keep
          available out of its  authorized  and unissued  shares of Common Stock
          solely for the purpose of issuance upon  conversion of this  Debenture
          and payment of interest on this  Debenture,  each as herein  provided,
          free from preemptive  rights or any other actual  contingent  purchase
          rights of persons other than the Holder,  not less than such number of
          shares  of the  Common  Stock  as  shall  (subject  to any  additional
          requirements of the Obligor as to reservation of such shares set forth
          in this  Debenture) be issuable  (taking into account the  adjustments
          and restrictions of Sections 2(b) and 3(c)) upon the conversion of the
          outstanding principal amount of this Debenture and payment of interest
          hereunder.  The Obligor covenants that all shares of Common Stock that
          shall  be  so  issuable  shall,   upon  issue,  be  duly  and  validly
          authorized,   issued  and  fully  paid,   nonassessable  and,  if  the
          Underlying Shares  Registration  Statement has been declared effective
          under the  Securities  Act,  registered  for public sale in accordance
          with such Underlying Shares Registration Statement.

     (e)  Upon a conversion hereunder the Obligor shall not be required to issue
          stock  certificates  representing  fractions  of shares of the  Common
          Stock, but may if otherwise permitted,  make a cash payment in respect
          of any final  fraction  of a share  based on the  Closing Bid Price at
          such time.  If the Obligor  elects  not, or is unable,  to make such a
          cash payment,  the Holder shall be entitled to receive, in lieu of the
          final fraction of a share, one whole share of Common Stock.

     (f)  The  issuance  of  certificates  for  shares  of the  Common  Stock on
          conversion  of this  Debenture  shall be made  without  charge  to the
          Holder thereof for any documentary  stamp or similar taxes that may be
          payable  in  respect  of the issue or  delivery  of such  certificate,
          provided  that the  Obligor  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 Holder of such  Debenture  so  converted  and the  Obligor
          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 Obligor  the amount of such tax or shall have  established
          to the satisfaction of the Obligor that such tax has been paid.

     (g)  Any notices,  consents,  waivers or other  communications  required or
          permitted  to be given  under the terms  hereof must be in writing and
          will  be  deemed  to have  been  delivered:  (i)  upon  receipt,  when
          delivered  personally;  (ii)  upon  receipt,  when  sent by  facsimile
          (provided    confirmation   of   transmission   is   mechanically   or
          electronically  generated and kept on file by the sending  party);  or
          (iii) one (1) trading day after  deposit with a nationally  recognized
          overnight  delivery  service,  in each case properly  addressed to the
          party to receive the same.  The addresses  and  facsimile  numbers for
          such communications shall be:

breach  of such  provision  or of any  breach  of any  other  provision  of this
Debenture. The failure of the Holder to insist upon strict adherence to any term

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  shall violate
applicable laws governing  usury,  the applicable rate of interest due hereunder
shall  automatically be lowered to equal the maximum permitted rate of interest.
The Obligor  covenants  (to the extent that it may lawfully do so) that it shall
not at any time insist upon,  plead, or in any manner  whatsoever  claim or take
the benefit or advantage of, any stay, extension or usury law or other law which
would  prohibit  or forgive  the  Obligor  from paying all or any portion of the
principal of or interest on this  Debenture  as  contemplated  herein,  wherever
enacted,  now or at any time  hereafter  in  force,  or  which  may  affect  the
covenants or the performance of this  indenture,  and the Obligor (to the extent
it may lawfully do so) hereby  expressly waives all benefits or advantage of any
such law,  and  covenants  that it will not, by resort to any such law,  hinder,
delay or impeded the  execution of any power herein  granted to the Holder,  but
will  suffer and permit  the  execution  of every such as though no such law has
been enacted.

     Section 13. 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.

     Section 14. THE PARTIES HEREBY  KNOWINGLY,  VOLUNTARILY  AND  INTENTIONALLY
WAIVE  THE  RIGHT  ANY OF THEM  MAY HAVE TO A TRIAL  BY JURY IN  RESPECT  OF ANY
LITIGATION  BASED  HEREON OR ARISING OUT OF,  UNDER OR IN  CONNECTION  WITH THIS
AGREEMENT  OR ANY  TRANSACTION  DOCUMENT  OR ANY  COURSE OF  CONDUCT,  COURSE OF
DEALING,  STATEMENTS  (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY.  THIS
PROVISION  IS  A  MATERIAL  INDUCEMENT  FOR  THE  PARTIES'  ACCEPTANCE  OF  THIS
AGREEMENT.
