         Section 2.   Interest.

         a) Payment of Interest. The Company shall pay interest to the Holder on
     the aggregate  unconverted and then  outstanding  principal  amount of this
     Debenture at the rate per annum equal to the Prime Rate for the  applicable
     Interest Period plus 1.5%, or such lesser rate as shall be the highest rate
     permitted  by  applicable  law,  payable  monthly  on the first day of each
     month,  beginning on the first such date after the Original  Issue Date, on
     each  Monthly  Redemption  Date (as to that  principal  amount  then  being
     redeemed),  on each Conversion Date (as to that principal amount then being
     converted),  on each Optional  Redemption Date (as to that principal amount
     then being  redeemed)  and on the Maturity  Date (except  that, if any such
     date is not a  Business  Day,  then such  payment  shall be due on the next
     succeeding Business Day), in cash via wire transfer.  At any time following
     the  Effective  Date,  the interest  rate for any Interest  Period shall be
     decreased  by 2% to the  extent the  average of the five VWAPs  immediately
     prior to such  Interest  Period  (the  "Trigger  Price")  exceeds  the then
     applicable Conversion Price by 25% (and shall be decreased by an additional
     2% for  every  successive  25%  that the  Trigger  Price  exceeds  the then
     applicable Conversion Price but in no event shall the interest rate be less
     than 0%). By way of an example, if the interest rate for an Interest Period
     as  determined  pursuant to the first  sentence of this section would be 5%
     and the  Trigger  Price  immediately  prior to such period is $5.00 and the
     then  applicable  Conversion  Price is $4.00,  the  interest  rate for such
     Interest  Period would be 3%. Any such decrease shall be applicable only as
     to the then  applicable  Interest  Period  and shall not be  applicable  to
     successive Interest Periods which shall be calculated  independently of any
     preceding  Interest  Periods.  Accordingly,  in the example  above,  if the
     Trigger  Price  as to the next  Interest  Period  is less  than  $4.00,  no
     reduction shall be made as to the interest rate for such period.

         b) Interest Calculations.  Interest shall be calculated on the basis of
     a 360-day year and shall accrue daily commencing on the Original Issue Date
     until payment in full of the principal  sum,  together with all accrued and
     unpaid interest and other amounts which may become due hereunder,  has been
     made.  Interest shall cease to accrue with respect to any principal  amount
     converted, provided that the Company in fact delivers the Conversion Shares
     within the time period  required by Section  4(d)(ii).  Interest  hereunder
     will be paid to the Person in whose name this  Debenture is  registered  on
     the records of the Company  regarding  registration  and  transfers of this
     Debenture (the "Debenture Register").

         c) Late  Fee.  All  overdue  accrued  and  unpaid  interest  to be paid
     hereunder  shall  entail a late fee at the rate of 18% per  annum  (or such
     lower maximum amount of


                                       7


     interest  permitted to be charged under applicable law) ("Late Fees") which
     will accrue daily, from the date such interest is due hereunder through and
     including the date of payment.

         d)  Prepayment.  Except as otherwise set forth in this  Debenture,  the
     Company  may  not  prepay  any  portion  of the  principal  amount  of this
     Debenture without the prior written consent of the Holder.

         Section 3.   Registration of Transfers and Exchanges.

         a) Different Denominations. This Debenture is exchangeable for an equal
     aggregate   principal   amount  of  Debentures   of  different   authorized
     denominations, as requested by the Holder surrendering the same. No service
     charge will be made for such registration of transfer or exchange.

         b) Investment  Representations.  This Debenture has been issued subject
     to certain  investment  representations of the original Holder set forth in
     the  Purchase  Agreement  and  may be  transferred  or  exchanged  only  in
     compliance  with the Purchase  Agreement and  applicable  federal and state
     securities laws and regulations.

         c) Reliance on  Debenture  Register.  Prior to due  presentment  to the
     Company for  transfer of this  Debenture,  the Company and any agent of the
     Company  may  treat  the  Person  in  whose  name  this  Debenture  is duly
     registered on the Debenture Register as the owner hereof for the purpose of
     receiving payment as herein provided and for all other purposes, whether or
     not this  Debenture is overdue,  and neither the Company nor any such agent
     shall be affected by notice to the contrary.

         Section 4.   Conversion.

         a)  Voluntary  Conversion.  At any time after the  Original  Issue Date
     until this  Debenture is no longer  outstanding,  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  (subject  to the
     limitations  on conversion  set forth in Section 4(c)  hereof).  The Holder
     shall effect conversions by delivering to the Company the form of Notice of
     Conversion   attached  hereto  as  Annex  A  (a  "Notice  of  Conversion"),
     specifying  therein the principal  amount of this Debenture to be converted
     and the date on which such  conversion  is to be  effected  (a  "Conversion
     Date").  If no Conversion Date is specified in a Notice of Conversion,  the
     Conversion  Date  shall be the date  that  such  Notice  of  Conversion  is
     provided hereunder.  To effect conversions hereunder,  the Holder shall not
     be required to physically  surrender  this  Debenture to the Company unless
     the entire principal amount of this Debenture has been so converted and all
     accrued but unpaid interest  thereon has been paid.  Conversions  hereunder
     shall have the effect of lowering the outstanding  principal amount of this
     Debenture in an amount equal to the applicable  conversion.  The Holder and
     the Company shall maintain  records showing the principal  amount converted
     and the date of such  conversions.  The Company shall deliver any objection
     to any  Notice of  Conversion  within 1  Business  Day of  receipt  of such
     notice.



                                       8


     In the event of any dispute or discrepancy, the records of the Holder shall
     be controlling  and  determinative  in the absence of manifest  error.  The
     Holder and any assignee,  by acceptance of this Debenture,  acknowledge and
     agree  that,  by  reason of the  provisions  of this  paragraph,  following
     conversion  of a portion of this  Debenture,  the  unpaid  and  unconverted
     principal  amount of this  Debenture  may be less than the amount stated on
     the face hereof.

         b) Conversion  Price.  The conversion price in effect on any Conversion
     Date  shall  be  equal  to  $1.738  (subject  to  adjustment  herein)  (the
     "Conversion Price").

         c) Conversion Limitations.

               i. Trading Market Limitations. Notwithstanding anything herein to
          the contrary, if the Company has not obtained Shareholder Approval (as
          defined below), then the Company may not issue upon conversion of this
          Debenture,  a number of shares of Common Stock which,  when aggregated
          with any shares of Common Stock issued prior to such  Conversion  Date
          (A)  pursuant  to any  Debentures  issued  pursuant  to  the  Purchase
          Agreement  and (B)  pursuant to any  Warrants  issued  pursuant to the
          Purchase  Agreement,  would exceed  19.999% of the number of shares of
          Common Stock outstanding on the Trading Day immediately  preceding the
          Original Issue Date (such number of shares,  the "Issuable  Maximum").
          Each Holder  shall be entitled  to a portion of the  Issuable  Maximum
          equal to the quotient obtained by dividing (x) the aggregate principal
          amount  of the  Debenture(s)  issued  and sold to such  Holder  on the
          Original  Issue  Date by (y) the  aggregate  principal  amount  of all
          Debentures  issued and sold by the Company on the Original Issue Date.
          If any  Holder  shall no  longer  hold  the  Debenture(s),  then  such
          Holder's  remaining portion of the Issuable Maximum shall be allocated
          pro-rata among the remaining  Holders.  If on any Conversion Date: (1)
          the applicable Conversion Price then in effect is such that the shares
          issuable under this Debenture on any Conversion Date together with the
          aggregate number of shares of Common Stock that would then be issuable
          upon  conversion  in full of all  then  outstanding  Debentures  would
          exceed the Issuable Maximum, and (2) the Company's  shareholders shall
          not have  previously  approved the  transactions  contemplated  by the
          Transaction Documents, if any (the "Shareholder  Approval"),  then the
          Company shall issue to the Holder  requesting a conversion a number of
          shares of Common Stock equal to such Holder's  pro-rata portion (which
          shall be  calculated  pursuant  to the terms  hereof) of the  Issuable
          Maximum and, with respect to the remainder of the aggregate  principal
          amount  of the  Debentures  then  held  by  such  Holder  for  which a
          conversion in accordance  with the applicable  conversion  price would
          result in an  issuance  of  shares  of Common  Stock in excess of such
          Holder's  pro-rata portion (which shall be calculated  pursuant to the
          terms hereof) of the Issuable  Maximum (the "Excess  Principal"),  the
          Company shall be prohibited from converting such Excess Principal, and
          shall notify the Holder of the reason  therefor.  This Debenture shall
          thereafter   be   unconvertible   to  such  extent  until  and  unless
          Shareholder  Approval



                                       9


          is subsequently obtained, but this Debenture shall otherwise remain in
          full force and effect.

               ii.  Holder's  Restriction on  Conversion.  The Company shall not
          effect any conversion of this Debenture, and the Holder shall not have
          the right to  convert  any  portion  of this  Debenture,  pursuant  to
          Section 4(a) or  otherwise,  to the extent that after giving effect to
          such conversion,  the Holder (together with the Holder's  Affiliates),
          as  set  forth  on  the  applicable   Notice  of   Conversion,   would
          beneficially  own in  excess  of 4.99% of the  number of shares of the
          Common  Stock  outstanding  immediately  after  giving  effect to such
          conversion.  For  purposes of the  foregoing  sentence,  the number of
          shares  of  Common  Stock  beneficially  owned by the  Holder  and its
          Affiliates shall include the number of shares of Common Stock issuable
          upon   conversion  of  this   Debenture  with  respect  to  which  the
          determination  of such  sentence is being made,  but shall exclude the
          number of shares of Common  Stock  which  would be  issuable  upon (A)
          conversion of the  remaining,  nonconverted  portion of this Debenture
          beneficially  owned by the  Holder  or any of its  Affiliates  and (B)
          exercise or conversion of the unexercised or  nonconverted  portion of
          any other securities of the Company  (including,  without  limitation,
          any other  Debentures  or the  Warrants)  subject to a  limitation  on
          conversion or exercise  analogous to the limitation  contained  herein
          beneficially  owned by the Holder or any of its Affiliates.  Except as
          set forth in the  preceding  sentence,  for  purposes of this  Section
          4(c)(ii),  beneficial ownership shall be calculated in accordance with
          Section  13(d)  of the  Exchange  Act and the  rules  and  regulations
          promulgated thereunder. To the extent that the limitation contained in
          this section applies,  the  determination of whether this Debenture is
          convertible (in relation to other  securities owned by the Holder) and
          of which a portion of this  Debenture is  convertible  shall be in the
          sole  discretion  of such  Holder.  To  ensure  compliance  with  this
          restriction,  the Holder  will be deemed to  represent  to the Company
          each time it  delivers  a Notice  of  Conversion  that such  Notice of
          Conversion  has  not  violated  the  restrictions  set  forth  in this
          paragraph  and the  Company  shall  have no  obligation  to  verify or
          confirm  the  accuracy  of  such   determination.   In   addition,   a
          determination  as to any group status as  contemplated  above shall be
          determined  in  accordance  with Section 13(d) of the Exchange Act and
          the rules and regulations promulgated thereunder. For purposes of this
          Section 4(c)(ii),  in determining the number of outstanding  shares of
          Common Stock, the Holder may rely on the number of outstanding  shares
          of Common  Stock as reflected  in (x) the  Company's  most recent Form
          10-Q or Form  10-K,  as the  case  may be,  (y) a more  recent  public
          announcement  by the Company or (z) any other notice by the Company or
          the  Company's  Transfer  Agent  setting forth the number of shares of
          Common  Stock  outstanding.  Upon the  written or oral  request of the
          Holder,  the Company shall within two Trading Days confirm  orally and
          in writing  to the  Holder  the number of shares of Common  Stock then
          outstanding.  In any case, the number of outstanding  shares of Common
          Stock shall be  determined  after giving  effect to the  conversion or
          exercise of securities of the Company,  including this  Debenture,  by
          the Holder or its Affiliates since the date as of which such number of
          outstanding  shares of


                                       10


          Common Stock was reported.  The provisions of this Section 4(c) may be
          waived by the Holder,  at the  election  of the Holder,  upon not less
          than 61 days' prior notice to the Company,  and the provisions of this
          Section  4(c)  shall  continue  to apply  until such 61st day (or such
          later date, as  determined by the Holder,  as may be specified in such
          notice  of  waiver).   The  provisions  of  this  paragraph  shall  be
          implemented in a manner  otherwise than in strict  conformity with the
          terms of this Section 4(c) to correct this  paragraph  (or any portion
          hereof) which may be defective or inconsistent with the intended 4.99%
          beneficial ownership limitation herein contained or to make changes or
          supplements  necessary or  desirable  to properly  give effect to such
          4.99%  limitation.  The limitations  contained in this paragraph shall
          apply to a successor  holder of this Debenture.  The holders of Common
          Stock  of the  Company  shall  be third  party  beneficiaries  of this
          Section  4(c) and the Company may not waive this  Section 4(c) without
          the consent of holders of a majority of its Common Stock.

         d) Mechanics of Conversion

               i.  Conversion  Shares  Issuable  Upon  Conversion  of  Principal
          Amount.  The  number  of  shares  of  Common  Stock  issuable  upon  a
          conversion  hereunder shall be determined by the quotient  obtained by
          dividing (x) the outstanding  principal amount of this Debenture to be
          converted by (y) the Conversion Price. i.

               ii. Delivery of Certificate Upon Conversion. Not later than three
          Trading Days after any  Conversion  Date,  the Company will deliver or
          cause to be delivered to the Holder (A) a certificate or  certificates
          representing the Conversion  Shares which shall be free of restrictive
          legends and  trading  restrictions  (other than those  required by the
          Purchase Agreement)  representing the number of shares of Common Stock
          being acquired upon the conversion of this Debenture and (B) an amount
          in cash  via  wire  transfer  in the  amount  of  accrued  and  unpaid
          interest.  The  Company  shall,  if  available  and if  allowed  under
          applicable  securities  laws,  use its best  efforts  to  deliver  any
          certificate  or  certificates  required to be delivered by the Company
          under  this  Section   electronically  through  the  Depository  Trust
          Corporation or another  established  clearing  corporation  performing
          similar functions.

               iii.  Failure  to  Deliver  Certificates.  If in the  case of any
          Notice  of  Conversion  such   certificate  or  certificates  are  not
          delivered  to or as  directed  by the  applicable  Holder by the third
          Trading Day after a Conversion  Date,  the Holder shall be entitled by
          written  notice to the Company at any time on or before its receipt of
          such   certificate  or  certificates   thereafter,   to  rescind  such
          conversion,  in which event the Company shall  immediately  return the
          certificates  representing  the  principal  amount  of this  Debenture
          tendered for conversion.

               iv.  Obligation  Absolute;  Partial  Liquidated  Damages.  If the
          Company fails for any reason to deliver to the Holder such certificate
          or certificates


                                       11


          pursuant  to  Section  4(d)(ii)  by the  third  Trading  Day after the
          Conversion  Date,  the Company  shall pay to such Holder,  in cash, as
          liquidated  damages and not as a penalty,  for each $1000 of principal
          amount being  converted,  $10 per Trading Day  (increasing  to $20 per
          Trading Day after 5 Trading Days after such  damages  begin to accrue)
          for  each  Trading  Day  after  such  third  Trading  Day  until  such
          certificates  are  delivered.  The Company's  obligations to issue and
          deliver the  Conversion  Shares upon  conversion of this  Debenture in
          accordance  with the terms  hereof  are  absolute  and  unconditional,
          irrespective  of any action or  inaction  by the Holder to enforce the
          same, any waiver or consent with respect to any provision hereof,  the
          recovery of any  judgment  against any Person or any action to enforce
          the same,  or any  setoff,  counterclaim,  recoupment,  limitation  or
          termination,  or any  breach or  alleged  breach by the  Holder or any
          other  Person of any  obligation  to the Company or any  violation  or
          alleged  violation  of law by the  Holder  or any  other  person,  and
          irrespective  of any other  circumstance  which might  otherwise limit
          such  obligation of the Company to the Holder in  connection  with the
          issuance of such Conversion Shares;  provided,  however, such delivery
          shall not  operate as a waiver by the  Company of any such  action the
          Company may have  against the Holder.  In the event the Holder of this
          Debenture  shall  elect  to  convert  any or  all  of the  outstanding
          principal amount hereof,  the Company may not refuse  conversion based
          on any claim that the Holder or any one associated or affiliated  with
          the Holder has been engaged in any violation of law,  agreement or for
          any other  reason,  unless,  an  injunction  from a court,  on notice,
          restraining  and  or  enjoining  conversion  of all or  part  of  this
          Debenture  shall have been sought and obtained and the Company posts a
          surety bond for the benefit of the Holder in the amount of 150% of the
          principal  amount of this Debenture  outstanding,  which is subject to
          the injunction, which bond shall remain in effect until the completion
          of  arbitration/litigation  of the dispute  and the  proceeds of which
          shall be payable to such Holder to the extent it obtains judgment.  In
          the absence of an injunction  precluding  the same,  the Company shall
          issue  Conversion  Shares  or, if  applicable,  cash,  upon a properly
          noticed  conversion.  Nothing  herein shall limit a Holder's  right to
          pursue  actual  damages or declare  an Event of  Default  pursuant  to
          Section 8 herein  for the  Company's  failure  to  deliver  Conversion
          Shares within the period  specified  herein and such Holder shall have
          the right to pursue all  remedies  available to it at law or in equity
          including, without limitation, a decree of specific performance and/or
          injunctive  relief. The exercise of any such rights shall not prohibit
          the  Holder  from  seeking to enforce  damages  pursuant  to any other
          Section hereof or under applicable law.

               v.   Compensation   for  Buy-In  on  Failure  to  Timely  Deliver
          Certificates  Upon  Conversion.   In  addition  to  any  other  rights
          available  to the  Holder,  if the  Company  fails  for any  reason to
          deliver to the Holder such  certificate  or  certificates  pursuant to
          Section  4(d)(ii) by the third Trading Day after the Conversion  Date,
          and if after such third  Trading  Day the  Holder is  required  by its
          brokerage  firm  to  purchase  (in  an  open  market   transaction  or
          otherwise)  Common Stock to deliver in  satisfaction of a sale by such
          Holder of the Conversion Shares


                                       12


          which  the  Holder  anticipated  receiving  upon  such  conversion  (a
          "Buy-In"),  then the  Company  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 actual  sale price of the
          Common Stock at the time of the sale (including brokerage commissions,
          if any) giving rise to such purchase  obligation and (B) at the option
          of the Holder,  either  reissue (if  surrendered)  this Debenture in a
          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 Company timely complied with
          its delivery requirements under Section 4(d)(ii).  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 this
          Debenture  with  respect  to  which  the  actual  sale  price  of  the
          Conversion  Shares  at the  time  of  the  sale  (including  brokerage
          commissions,  if any) giving rise to such  purchase  obligation  was a
          total  of  $10,000  under  clause  (A)  of the  immediately  preceding
          sentence,  the Company shall be required to pay the Holder $1,000. The
          Holder shall provide the Company written notice indicating the amounts
          payable  to the  Holder  in  respect  of the  Buy-In.  Notwithstanding
          anything  contained  herein to the contrary,  if a Holder requires the
          Company to make  payment  in  respect  of a Buy-In for the  failure to
          timely deliver  certificates  hereunder and the Company timely pays in
          full such  payment,  the  Company  shall not be  required  to pay such
          Holder  liquidated  damages under  Section  4(d)(iv) in respect of the
          certificates resulting in such Buy-In.

               vi.  Reservation of Shares Issuable Upon Conversion.  The Company
          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  as herein
          provided,  free from preemptive  rights or any other actual contingent
          purchase  rights  of  persons  other  than the  Holder  (and the other
          holders of the Debentures), not less than such number of shares of the
          Common Stock as shall  (subject to the terms and  conditions set forth
          in the  Purchase  Agreement)  be  issuable  (taking  into  account the
          adjustments and  restrictions of Section 5) upon the conversion of the
          outstanding principal amount of this Debenture.  The Company 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  Registration  Statement is then  effective
          under the  Securities  Act,  registered  for public sale in accordance
          with such Registration Statement.

               vii. Fractional Shares.  Upon a conversion  hereunder the Company
          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


                                       13


          respect  of any final  fraction  of a share  based on the VWAP at such
          time.  If the Company  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.

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

         Section 5.        Certain Adjustments.

         a) Stock Dividends and Stock Splits. If the Company,  at any time while
     this Debenture is outstanding: (A) pays a stock dividend or otherwise makes
     a distribution or  distributions on shares of its Common Stock or any other
     equity or equity  equivalent  securities  payable in shares of Common Stock
     (which,  for  avoidance  of doubt,  shall not  include any shares of Common
     Stock issued by the Company  pursuant to this  Debenture),  (B)  subdivides
     outstanding  shares of Common  Stock into a larger  number of  shares,  (C)
     combines  (including by way of reverse stock split)  outstanding  shares of
     Common  Stock  into  a  smaller   number  of  shares,   or  (D)  issues  by
     reclassification  of shares of the Common Stock any shares of capital stock
     of the Company, 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  immediately  before such
     event and of which the denominator  shall be the number of shares of Common
     Stock  outstanding  immediately  after  such  event.  Any  adjustment  made
     pursuant to this  Section  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.

         b) Subsequent  Equity Sales. If the Company or any Subsidiary  thereof,
     as  applicable,  at any time while this  Debenture  is  outstanding,  shall
     offer, sell, grant any option to purchase or offer, sell or grant any right
     to reprice  its  securities,  or  otherwise  dispose of or issue any Common
     Stock or Common Stock Equivalents entitling any Person to acquire shares of
     Common Stock, at an effective price per share less than the then Conversion
     Price (such lower price,  the "Base  Conversion  Price" and such  issuances
     collectively,  a "Dilutive Issuance"), as adjusted hereunder (if the holder
     of the Common  Stock or Common  Stock  Equivalents  so issued  shall at any
     time, whether by operation of


                                       14


     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 an  effective  price per share which is
     less  than the  Conversion  Price,  such  issuance  shall be deemed to have
     occurred  for less than the  Conversion  Price on such date of the Dilutive
     Issuance),  then the Conversion  Price shall be reduced by multiplying  the
     Conversion  Price by a fraction,  the  numerator  of which is the number of
     shares of Common  Stock  issued and  outstanding  immediately  prior to the
     Dilutive  Issuance  plus the  number of shares  of Common  Stock  which the
     offering  price  for such  Dilutive  Issuance  would  purchase  at the then
     Conversion  Price,  and the  denominator  of which  shall be the sum of the
     number of shares of Common Stock issued and outstanding  immediately  prior
     to the  Dilutive  Issuance  plus the  number of  shares of Common  Stock so
     issued  or  issuable  in  connection  with  the  Dilutive  Issuance.   Such
     adjustment  shall  be made  whenever  such  Common  Stock or  Common  Stock
     Equivalents are issued.  Notwithstanding the foregoing,  no adjustment will
     be made under this  Section  5(b) in  respect  of an Exempt  Issuance.  The
     Company shall notify the Holder in writing,  no later than the Business Day
     following  the  issuance of any Common  Stock or Common  Stock  Equivalents
     subject to this section,  indicating therein the applicable issuance price,
     or of applicable  reset price,  exchange price,  conversion price and other
     pricing terms (such notice the "Dilutive Issuance Notice"). For purposes of
     clarification,  whether or not the  Company  provides  a Dilutive  Issuance
     Notice  pursuant to this Section 5(b),  upon the occurrence of any Dilutive
     Issuance,  after the date of such Dilutive  Issuance the Holder is entitled
     to receive a number of  Conversion  Shares  based upon the Base  Conversion
     Price  regardless  of  whether  the  Holder  accurately  refers to the Base
     Conversion Price in the Notice of Conversion.

         c) Pro Rata  Distributions.  If the  Company,  at any time  while  this
     Debenture is outstanding,  shall  distribute to all holders of Common Stock
     (and not to the holders of the Debenture)  evidences of its indebtedness or
     assets  (including  cash and cash  dividends)  or  rights  or  warrants  to
     subscribe  for or  purchase  any  security,  then in  each  such  case  the
     Conversion  Price shall be adjusted by multiplying such Conversion Price in
     effect  immediately  prior to the record  date fixed for  determination  of
     stockholders  entitled to receive such  distribution by a fraction of which
     the  denominator  shall  be  the  VWAP  determined  as of the  record  date
     mentioned  above,  and of which  the  numerator  shall be such VWAP on such
     record  date less the then fair  market  value at such  record  date of the
     portion  of  such  assets  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.

         d)  Fundamental  Transaction.  If, at any time while this  Debenture is
     outstanding,  (A) the Company  effects any merger or  consolidation  of the
     Company with


                                       15


     or  into  another  Person,  (B)  the  Company  effects  any  sale of all or
     substantially all of its assets in one or a series of related transactions,
     (C) any tender offer or exchange  offer  (whether by the Company or another
     Person)  is  completed  pursuant  to which  holders  of  Common  Stock  are
     permitted to tender or exchange their shares for other securities,  cash or
     property,  or (D) the Company  effects any  reclassification  of the Common
     Stock or any compulsory  share exchange  pursuant to which the Common Stock
     is effectively  converted into or exchanged for other  securities,  cash or
     property (in any such case,  a  "Fundamental  Transaction"),  then upon any
     subsequent conversion of this Debenture, the Holder shall have the right to
     receive,  for each Conversion Share that would have been issuable upon such
     conversion   immediately  prior  to  the  occurrence  of  such  Fundamental
     Transaction, the same kind and amount of securities, cash or property as it
     would have been entitled to receive upon the occurrence of such Fundamental
     Transaction  if  it  had  been,   immediately  prior  to  such  Fundamental
     Transaction,  the  holder  of one  share of Common  Stock  (the  "Alternate
     Consideration").  For purposes of any such conversion, the determination of
     the  Conversion  Price  shall be  appropriately  adjusted  to apply to such
     Alternate  Consideration  based on the  amount of  Alternate  Consideration
     issuable  in  respect  of one  share of  Common  Stock in such  Fundamental
     Transaction, and the Company shall apportion the Conversion Price among the
     Alternate  Consideration  in a reasonable  manner  reflecting  the relative
     value  of any  different  components  of the  Alternate  Consideration.  If
     holders of Common Stock are given any choice as to the securities,  cash or
     property to be received in a Fundamental Transaction, then the Holder shall
     be given the same choice as to the Alternate Consideration it receives upon
     any conversion of this Debenture following such Fundamental Transaction. To
     the extent necessary to effectuate the foregoing provisions,  any successor
     to the Company or surviving  entity in such Fundamental  Transaction  shall
     issue  to  the  Holder  a  new  debenture  consistent  with  the  foregoing
     provisions and evidencing the Holder's right to convert such debenture into
     Alternate  Consideration.  The terms of any  agreement  pursuant to which a
     Fundamental  Transaction is effected shall include terms requiring any such
     successor  or  surviving  entity  to  comply  with the  provisions  of this
     paragraph  (d) and insuring that this  Debenture  (or any such  replacement
     security)  will be  similarly  adjusted  upon  any  subsequent  transaction
     analogous to a Fundamental Transaction.

         e) Calculations. All calculations under this Section 5 shall be made to
     the nearest cent or the nearest 1/100th of a share, as the case may be. For
     purposes of this  Section 5, the number of shares of Common Stock deemed to
     be issued and outstanding as of a given date shall be the sum of the number
     of shares of Common Stock (excluding  treasury  shares,  if any) issued and
     outstanding.

         f) Notice to the Holder.

               i. Adjustment to Conversion Price.  Whenever the Conversion Price
          is  adjusted  pursuant  to any of this  Section 5, the  Company  shall
          promptly  mail to each Holder a notice  setting  forth the  Conversion
          Price after such adjustment and setting forth a brief statement of the
          facts requiring such adjustment. If the Company issues a variable rate
          security,  despite the prohibition  thereon in the


                                       16


          Purchase Agreement,  the Company shall be deemed to have issued Common
          Stock or Common Stock Equivalents at the lowest possible conversion or
          exercise price at which such  securities may be converted or exercised
          in the case of a Variable Rate Transaction (as defined in the Purchase
          Agreement).

               ii.  Notice to Allow  Conversion  by Holder.  If (A) the  Company
          shall  declare a dividend  (or any other  distribution)  on the Common
          Stock;  (B) the  Company  shall  declare a special  nonrecurring  cash
          dividend on or a redemption of the Common Stock; (C) the Company 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 Company shall be required in connection with any  reclassification
          of the Common Stock, any  consolidation or merger to which the Company
          is a party,  any sale or transfer of all or  substantially  all of the
          assets of the Company,  of any compulsory  share exchange  whereby the
          Common Stock is converted into other securities, cash or property; (E)
          the Company shall authorize the voluntary or involuntary  dissolution,
          liquidation or winding up of the affairs of the Company; then, in each
          case,  the  Company  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  addresses  as it shall
          appear upon the stock books of the Company,  at least 20 calendar days
          prior  to  the  applicable   record  or  effective  date   hereinafter
          specified,  a notice  stating  (x) the date on which a record is to be
          taken for the  purpose  of such  dividend,  distribution,  redemption,
          rights or warrants,  or if a record is not to be taken, the date as of
          which the holders of the Common Stock of record to be entitled to such
          dividend,  distributions,  redemption,  rights or  warrants  are to be
          determined   or  (y)  the   date  on  which   such   reclassification,
          consolidation, merger, sale, transfer or share exchange is expected to
          become  effective  or close,  and the date as of which it is  expected
          that  holders  of the  Common  Stock of record  shall be  entitled  to
          exchange  their  shares of the Common  Stock for  securities,  cash or
          other property deliverable upon such reclassification,  consolidation,
          merger, sale, transfer or share exchange;  provided,  that the failure
          to 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 period  commencing the date of such notice
          to the effective date of the event triggering such notice.

         Section 6.        Redemption.

         a)  Optional  Redemption  at  Election  of  Company.   Subject  to  the
     provisions  of this  Section  6, at any time  after  the date  hereof,  the
     Company may deliver a notice to the Holder (an "Optional Redemption Notice"
     and the date such  notice  is deemed  delivered  hereunder,  the  "Optional
     Redemption Notice Date") of its irrevocable  election to redeem some or all
     of the  then  outstanding  Debentures,  for an  amount,  in cash  via  wire
     transfer,  equal to the Optional  Redemption Amount on the 20th Trading Day
     following


                                       17


     the Optional  Redemption  Notice Date (such date, the "Optional  Redemption
     Date" and such redemption,  the "Optional Redemption") (provided,  however,
     the Company may pay up to 15% of the of the principal  amount  comprising a
     portion of the  Option  Redemption  Amount in shares of Common  Stock (at a
     price per share  equal to 90% of the  average  of the 10 VWAPs  immediately
     prior to the  applicable  Optional  Redemption  Date) if all of the  Equity
     Conditions  are  satisfied as to such shares and the other  conditions  set
     forth herein are satisfied).  The Optional Redemption Amount is due in full
     on the Optional  Redemption Date. The Company  covenants and agrees that it
     will honor all Notices of Conversion  tendered from the time of delivery of
     the Optional  Redemption  Notice through the date all amounts owing thereon
     are due and paid in full.

         b) Monthly  Redemption.  On each Monthly  Redemption  Date, the Company
     shall  redeem  the  Monthly  Redemption  Amount  plus  accrued  but  unpaid
     interest,  the sum of all  liquidated  damages and any other  amounts  then
     owing  to  such  Holder  in  respect  of  this   Debenture   (the  "Monthly
     Redemption").  The Monthly Redemption Amount due on each Monthly Redemption
     Date shall be paid in cash via wire transfer;  provided, however, as to any
     Monthly  Redemption  and upon 30 Trading  Days' prior  written  irrevocable
     notice  (the  "Monthly  Redemption  Notice"  and the 30 Trading  Day period
     immediately   following  the  Monthly   Redemption   Notice,  the  "Monthly
     Redemption  Period"),  in lieu of a cash redemption payment the Company may
     elect to pay all or part of the principal  amount  included in such Monthly
     Redemption  Amount in  Conversion  Shares in an amount not to exceed 10% of
     the total dollar  trading  volume of the Common Stock during the 10 Trading
     Days  immediately  prior to the applicable  Monthly  Redemption  Date (such
     dollar amount to be paid on a Monthly Redemption Date in Conversion Shares,
     the "Monthly Redemption Share Amount") based on a conversion price equal to
     85% of the  average  of the  lowest  3 VWAPs  during  the 10  Trading  Days
     immediately  prior to the applicable  Monthly  Redemption  Date (subject to
     adjustment for any stock dividend,  stock split, stock combination or other
     similar event affecting the Common Stock during such 10 Trading Day period)
     (the price calculated during the 10 Trading Day period immediately prior to
     the  Monthly  Redemption  Date,  the  "Monthly  Conversion  Price" and such
     period,  the "Monthly  Conversion  Period");  provided,  further,  that the
     Company  may not  pay  such  portion  of a  Monthly  Redemption  Amount  in
     Conversion  Shares unless,  (y) from the date the Holder  receives the duly
     delivered Monthly Redemption Notice through and until the date such Monthly
     Redemption is paid in full, the Equity Conditions, unless waived in writing
     by the Holder,  have been satisfied and (z) as to such Monthly  Redemption,
     prior to such Monthly  Redemption  Period (but not more than 5 Trading Days
     prior to the commencement of the Monthly  Redemption  Period),  the Company
     shall have  delivered to the Holder's  account  with The  Depository  Trust
     Company  a number of shares of  Common  Stock to be  applied  against  such
     Monthly Redemption Share Amount equal to the quotient of (x) the applicable
     Monthly  Redemption  Share Amount divided by (y) the then Conversion  Price
     (the "Pre-Redemption  Conversion Shares"). The Holder may convert, pursuant
     to  Section  4(a),  any  principal  amount of this  Debenture  subject to a
     Monthly  Redemption  at  any  time  prior  to the  date  that  the  Monthly
     Redemption  Amount and all amounts  owing thereon are due and paid in full.
     Unless  otherwise  indicated  by the  Holder  in the  applicable  Notice of


                                       18


     Conversion,  any principal  amount of this Debenture  converted  during the
     applicable  Monthly Redemption Period until the date the Monthly Redemption
     Amount  is paid in full  shall be first  applied  to the  principal  amount
     subject to the Monthly  Redemption  Amount  payable in cash and then to the
     Monthly  Redemption  Share Amount.  Any principal  amount of this Debenture
     converted during the applicable  Monthly Redemption Period in excess of the
     Monthly  Redemption  Amount  shall be applied  against  the last  principal
     amount of this  Debenture  scheduled to be redeemed  hereunder,  in reverse
     time  order  from  the  Maturity  Date;  provided,  however,  if  any  such
     conversion is applied to such Monthly Redemption Amount, the Pre-Redemption
     Conversion  Shares,  if any were  issued in  connection  with such  Monthly
     Redemption or were not already applied to such conversions,  shall be first
     applied against such conversion.  The Company  covenants and agrees that it
     will honor all Notice of  Conversions  tendered  up until such  amounts are
     paid in full. The Company's  determination  to pay a Monthly  Redemption in
     cash,  shares of Common  Stock or a  combination  thereof  shall be applied
     ratably to all of the  holders of the  Debentures  based on their (or their
     predecessor's)  initial  purchases of  Debentures  pursuant to the Purchase
     Agreement.  At any time the Company  delivers a notice to the Holder of its
     election to pay the Monthly  Redemption  Amount in shares of Common  Stock,
     the Company shall file a prospectus supplement pursuant to Rule 424 or file
     a Current Report on Form 8-K disclosing such election.

         c)  Additional  Redemption  Right.  Subject to the  provisions  of this
     Section 6, in addition to the  redemption  rights  above,  in the event the
     Company has not consummated the acquisition described in Section 4.9 of the
     Purchase  Agreement on or before  December  31, 2005,  at any time from the
     Original  Issue Date through  December 31, 2005,  the Company may deliver a
     notice to the Holder (a "Short  Term  Optional  Redemption  Notice") of its
     irrevocable  election  to  redeem  all (but not less  than all) of the then
     outstanding  Debentures,  for an amount,  in cash (except as to (iv) below)
     via wire transfer,  equal to the sum of (i) 102.5% of the principal  amount
     of the Debenture then outstanding,  (ii) accrued but unpaid interest, (iii)
     all  liquidated  damages and other  amounts due in respect of the Debenture
     and (iv) a warrant to purchase  shares of Common Stock as described  below.
     Such amount is due in full on the 30th  calendar day  following the date of
     the Short  Term  Optional  Redemption  Notice  (the  "Short  Term  Optional
     Redemption  Date"). If the Company fails to deliver a Short Term Redemption
     Notice on or before December 31, 2005, the Company shall no longer have the
     right to  exercise  a  redemption  under this  Section  6(c).  The  Company
     covenants and agrees that it will honor Notices of  Conversions of up to an
     aggregate of 50% of the principal amount of this Debenture then outstanding
     tendered  from the time of delivery of the Short Term  Optional  Redemption
     Notice through the date all amounts owing thereon are due and paid in full.
     In addition to the cash payment  described  above,  as partial  payment for
     such Short Term Optional  Redemption,  each Holder of  Debentures  shall be
     issued a warrant to purchase  their  pro-rata share (based on such Holder's
     Subscription  Amount  and the  aggregate  Subscription  Amounts  under  the
     Purchase   Agreement)  of  100,000  shares  of  Common  Stock  (subject  to
     adjustment for forward and reverse stock splits,  recapitalizations,  stock
     dividends  and  the  like),  in the  form  of  Exhibit  C to  the  Purchase
     Agreement,  which  warrants  shall be  exercisable  immediately  upon their
     issuance,  have a


                                       19


     term of exercise equal to 5 years and an exercise price equal to the lesser
     of the  exercise  price of the  Warrants  issued  pursuant to the  Purchase
     Agreement and 120% of the average Closing Price of the Common Stock for the
     ten Trading Days immediately  preceding the Short Term Optional  Redemption
     Date.

         d)  Redemption  Procedure.  The payment of cash pursuant to an Optional
     Redemption  or  Short  Term  Optional  Redemption  shall  be made  via wire
     transfer on the Optional  Redemption Date or Short Term Optional Redemption
     Date,  as  applicable.  If any portion of the cash  payment for an Optional
     Redemption  or Short  Term  Optional  Redemption  shall  not be paid by the
     Company by the  respective  due date,  interest shall accrue thereon at the
     rate of 18% per annum (or the maximum  rate  permitted by  applicable  law,
     whichever is less) until the payment of such amount, plus all amounts owing
     thereon is paid in full.  Alternatively,  if any  portion  of the  Optional
     Redemption  Amount or Short Term Optional  Redemption amount remains unpaid
     after such date,  the  Holders  subject to such  redemption  may elect,  by
     written notice to the Company given at any time  thereafter,  to invalidate
     ab initio such redemption, notwithstanding anything herein contained to the
     contrary, and, with respect the failure to honor the Optional Redemption as
     applicable,  the  Company  shall have no  further  right to  exercise  such
     Optional  Redemption.  Notwithstanding  anything  to the  contrary  in this
     Section 6, the Company's  determination  to redeem in cash or its elections
     under  Section  6(b)  shall be  applied  among the  Holders  of  Debentures
     ratably.  The Holder may elect to convert the outstanding  principal amount
     of the Debenture  pursuant to Section 4 prior to actual payment in cash for
     any  redemption  under  this  Section  6 by fax  delivery  of a  Notice  of
     Conversion to the Company.

         Section 7. Negative Covenants. So long as any portion of this Debenture
is outstanding, the Company will not and will not permit any of its Subsidiaries
to directly or  indirectly:  a) other than Permitted  Indebtedness,  enter into,
create,  incur,  assume,  guarantee  or  suffer to exist  any  indebtedness  for
borrowed  money of any kind,  including  but not limited to, a guarantee,  on or
with respect to any of its property or assets now owned or hereafter acquired or
any interest therein or any income or profits therefrom;

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

         c) amend its  certificate  of  incorporation,  bylaws or other  charter
     documents  so as to  materially  and  adversely  affect  any  rights of the
     Holder;

         d) repay, repurchase or offer to repay, repurchase or otherwise acquire
     more than a de minimis number of shares of its Common Stock or Common Stock
     Equivalents  other than as to the Conversion Shares to the extent permitted
     or required under the  Transaction  Documents or as otherwise  permitted by
     the Transaction Documents;



                                       20


         e) enter into any agreement with respect to any of the foregoing; or

         f) pay cash dividends or distributions on any equity  securities of the
     Company.

         Section 8.        Events of Default.

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

               i. any default in the payment of (A) the principal  amount of any
          Debenture,  or (B) interest  (including  Late Fees) on, or  liquidated
          damages  in  respect  of,  any  Debenture,  as and when the same shall
          become due and payable  (whether on a Conversion  Date or the Maturity
          Date or by  acceleration  or otherwise)  which default,  solely in the
          case of an interest  payment or other  default under clause (B) above,
          is not cured, within 3 Trading Days;

               ii. the  Company  shall  fail to  observe  or  perform  any other
          covenant  or  agreement  contained  in  this  Debenture  or any  other
          Debenture  (other than a breach by the Company of its  obligations  to
          deliver  shares of Common  Stock to the Holder upon  conversion  which
          breach is addressed in clause (xi) below) which  failure is not cured,
          if possible to cure, within the earlier to occur of (A) 5 Trading Days
          after notice of such default sent by the Holder or by any other Holder
          and (B)10  Trading Days after the Company  shall become or should have
          become aware of such failure;

               iii. a default or event of default  (subject to any grace or cure
          period  provided  for  in  the  applicable   agreement,   document  or
          instrument) shall occur under (A) any of the Transaction Documents, or

               x.  if,  during  the  Effectiveness  Period  (as  defined  in the

          acquisition  or sale of all or  substantially  all of its  assets or a
          similar  transaction  and in the  written  opinion  of  counsel to the
          Company, the Registration  Statement,  would be required to be amended
          to include  information  concerning  such  transactions or the parties
          thereto that is not available or may not be publicly  disclosed at the

          Agreement and the Company does not obtain Shareholder Approval.

         b) Remedies Upon Event of Default.  If any Event of Default occurs, 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 via wire
     transfer.  The aggregate  amount  payable upon an Event of Default shall be
     equal  to  the  Mandatory  Default  Amount.  Commencing  5 days  after  the
     occurrence   of  any  Event  of  Default   that  results  in  the  eventual
     acceleration of this  Debenture,  the interest rate on this Debenture shall
     accrue  at the rate of 18% per  annum,  or such  lower  maximum  amount  of
     interest  permitted to be charged under applicable law. Upon the payment in
     full of the Mandatory  Default  Amount on this entire  Debenture the Holder
     shall  promptly  surrender this Debenture to or as directed by the Company.
     The Holder need not provide and the Company 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 and the Holder shall have all rights as
     a Debenture  holder until such time, if any, as the full payment under this
     Section  shall have been  received by it. No such


                                       23


     rescission  or annulment  shall affect any  subsequent  Event of Default or
     impair any right consequent thereon.

         Section 9.        Miscellaneous.

         a) Notices.  Any and all notices or other  communications or deliveries

     number or  address  appears,  at the  principal  place of  business  of the
     Holder. Any notice or other communication or deliveries  hereunder shall be

         b)  Absolute  Obligation.  Except  as  expressly  provided  herein,  no
     provision of this  Debenture  shall alter or impair the  obligation  of the
     Company,  which is absolute and  unconditional,  to pay the  principal  of,
     interest and  liquidated  damages (if any) on, this  Debenture at the time,
     place,  and rate,  and in the coin or  currency,  herein  prescribed.  This
     Debenture is a direct debt obligation of the Company.  This Debenture ranks
     pari passu with all other  Debentures  now or  hereafter  issued  under the
     terms set forth herein.

         c) Lost or Mutilated  Debenture.  If this Debenture shall be mutilated,
     lost,  stolen or  destroyed,  the Company  shall  execute and  deliver,  in
     exchange  and  substitution  for  and  upon  cancellation  of  a  mutilated

     Debenture,  a new Debenture for the principal  amount of this  Debenture so
     mutilated,  lost,  stolen or destroyed but only upon receipt of evidence of
     such loss,  theft or  destruction of such  Debenture,  and of the ownership
     hereof,  and indemnity,  if requested,  all reasonably  satisfactory to the
     Company.

         d) Governing Law. All questions concerning the construction,  validity,
     enforcement and  interpretation  of this Debenture shall be governed by and
     construed and enforced in accordance with the internal laws of the State of
     New York,  without  regard to


                                       24


     the  principles  of conflicts  of law  thereof.  Each party agrees that all
     legal proceedings  concerning the interpretations,  enforcement and defense
     of the  transactions  contemplated  by any  of  the  Transaction  Documents
     (whether  brought  against  a party  hereto or its  respective  affiliates,
     directors, officers, shareholders,  employees or agents) shall be commenced
     in the state and federal courts sitting in the City of New York, Borough of
     Manhattan  (the "New York  Courts").  Each party hereto hereby  irrevocably
     submits  to the  exclusive  jurisdiction  of the New  York  Courts  for the
     adjudication of any dispute hereunder or in connection herewith or with any
     transaction contemplated hereby or discussed herein (including with respect
     to  the  enforcement  of  any of the  Transaction  Documents),  and  hereby
     irrevocably  waives,  and  agrees  not to  assert  in any  suit,  action or
     proceeding, any claim that it is not personally subject to the jurisdiction
     of any such  court,  or such New York Courts are  improper or  inconvenient
     venue for such proceeding.  Each party hereby  irrevocably  waives personal
     service of process and  consents to process  being served in any such suit,
     action or proceeding by mailing a copy thereof via  registered or certified
     mail or overnight delivery (with evidence of delivery) to such party at the
     address in effect for  notices to it under this  Debenture  and agrees that
     such service shall  constitute  good and sufficient  service of process and
     notice thereof.  Nothing  contained  herein shall be deemed to limit in any
     way any right to serve  process in any manner  permitted by law. Each party
     hereto  hereby  irrevocably  waives,  to the fullest  extent  permitted  by
     applicable law, any and all right to trial by jury in any legal  proceeding
     arising  out  of  or  relating  to  this  Debenture  or  the   transactions
     contemplated hereby. If either party shall commence an action or proceeding
     to enforce any provisions of this Debenture,  then the prevailing  party in
     such action or  proceeding  shall be  reimbursed by the other party for its
     attorneys   fees  and  other   costs  and   expenses   incurred   with  the
     investigation, preparation and prosecution of such action or proceeding.

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

         f) Severability. If any provision of this Debenture is invalid, illegal
     or unenforceable, the balance of this Debenture shall remain in effect, and
     if any provision is  inapplicable to any person or  circumstance,  it shall
     nevertheless  remain applicable to all other persons and circumstances.  If
     it shall be found that any  interest or other  amount  deemed  interest due
     hereunder violates  applicable laws governing usury, the applicable rate of
     interest due hereunder shall  automatically be lowered to equal the maximum
     permitted  rate of interest.  The Company  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
     Company  from paying all or any portion of the  principal of or interest on
     this Debenture as contemplated herein, wherever enacted, now or at any


                                       25


     time  hereafter  in  force,  or  which  may  affect  the  covenants  or the
     performance  of this  indenture,  and the  Company  (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.

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

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

         i)  Assumption.  Any successor to the Company or surviving  entity in a
     Fundamental  Transaction shall (i) assume in writing all of the obligations
     of the Company  under this  Debenture and the other  Transaction  Documents
     pursuant to written  agreements in form and substance  satisfactory  to the
     Holder (such approval not to be unreasonably  withheld or delayed) prior to
     such  Fundamental  Transaction  and  (ii)  to  issue  to the  Holder  a new
     debenture  of such  successor  entity  evidenced  by a  written  instrument
     substantially  similar in form and substance to this Debenture,  including,
     without  limitation,  having a principal  amount and interest rate equal to
     the principal  amounts and the interest rates of the Debentures held by the
     Holder and having similar  ranking to this Debenture,  and  satisfactory to
     the Holder (any such approval not to be unreasonably  withheld or delayed).
     The  provisions  of this Section 9(i) shall apply  similarly and equally to
     successive Fundamental  Transactions and shall be applied without regard to
     any limitations of this Debenture.

                              *********************
