or  registered  assigns (the  "Holder") the amount set out above as the Original
Principal   Amount  (as  reduced  pursuant  to  the  terms  hereof  pursuant  to

the Securities  Purchase Agreement (the "Agreement") of even date herewith among
the Holder and the Company. Certain capitalized terms used in this Debenture are
defined in Section 17.

(1)  GENERAL TERMS

     (a)  Payment of  Principal.  On or before  February 11,  2008,  the Company
          shall repay $1,000,000 of the Principal. On each Installment Date, the
          Company  shall pay to the  Holder an amount  equal to the  Installment
          Amount due on such  Installment  Date in accordance with Section 3. On
          the Maturity  Date,  the Company  shall pay to the Holder an amount in
          cash  representing  all  outstanding  Principal,  accrued  and  unpaid
          Interest.  The  "Maturity  Date" shall be February 11, 2009, as may be
          extended at the option of the Holder (i) in the event that, and for so
          long as, an Event of Default (as defined  below)  shall have  occurred
          and be continuing on the Maturity Date (as may be extended pursuant to
          this Section 1) or any event shall have  occurred and be continuing on
          the Maturity Date (as may be extended pursuant to this Section 1) that
          with the  passage of time and the  failure to cure would  result in an
          Event  of  Default.  Other  than  as  specifically  permitted  by this
          Debenture,  the  Company  may not prepay or redeem any  portion of the
          outstanding Principal without the prior written consent of the Holder

     (b)  Interest.  Interest shall accrue on the outstanding  principal balance
          hereof at an annual rate equal to ten percent (10%) ("Interest Rate").
          Interest  shall be  calculated  on the basis of a 365-day year and the
          actual number of days elapsed,  to the extent  permitted by applicable
          law.  Interest  hereunder  shall be paid  monthly  in  arrears on each
          Installment  Date and continuing until the Maturity Date (or sooner as
          provided  herein)  to the  Holder or its  assignee  in whose name this
          Debenture  is  registered  on the  records  of the  Company  regarding
          registration  and  transfers  of this  Debenture  at the option of the
          Company in cash.

     (c)  Security.  The  Debenture  is  secured  by  a  pledge  of  assets  and
          guaranties as set forth in the Security Documents.

               (B)  notice,  written or oral,  to any holder of this  Debenture,
               including  by way of public  announcement,  at any  time,  of its
               intention  not to comply  with a request for  conversion  of this

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

     (b)  During the time that any portion of this Debenture is outstanding,  if
          any Event of Default has occurred, the full unpaid 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  Company.
          Furthermore,  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.  The Holder need not provide and the Company hereby
          waives any presentment,  demand,  protest or other notice of any kind,
          (other  than  required  notice  of  conversion)  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.

(3)  COMPANY INSTALLMENT REDEMPTION.

     (a)  Installment Payments. On each applicable Installment Date, the Company
          shall pay to the Holder of this Debenture the  Installment  Amount due
          on such date by wire transfer of immediately available funds.

     (b)  Deferred  Installment  Amount.  Notwithstanding  any provision of this
          Section 3 to the  contrary,  the Holder  may, at its option and in its
          sole discretion,  deliver a written notice to the Company at least two
          (2) days prior to any Installment Date electing to have the payment of
          all or any  portion  of an  Installment  Amount  payable  on the  next
          Installment Date deferred to the Maturity Date. Any amount deferred to
          the Maturity  Date  pursuant to this  Section  3(c) shall  continue to
          accrue Interest through the Maturity Date.

     (c)  Company's Additional Cash Redemption.  The Company at its option shall
          have the  right to redeem  ("Optional  Redemption")  a portion  or all
          amounts   outstanding   under  this   Debenture  in  addition  to  any
          Installment  Amount prior to the Maturity Date provided that as of the
          date of the  Holder's  receipt  of a  Redemption  Notice  (as  defined
          herein) (i) the  Closing  Bid Price is less than the Fixed  Conversion
          Price,  and (ii) no Event of Default has  occurred.  The Company shall
          pay an amount equal to the principal amount being redeemed and accrued
          Interest,   (collectively  referred  to  as  the  "Company  Additional
          Redemption  Amount").  In order to make a redemption  pursuant to this
          Section,  the Company shall first provide written notice to the Holder
          of its  intention  to  make a  redemption  (the  "Redemption  Notice")
          setting  forth the amount of  Principal  it  desires to redeem.  After
          receipt  of the  Redemption  Notice  the  Holder  shall have three (3)
          Business  Days  to  elect  to  convert  all or  any  portion  of  this
          Debenture,  subject to the  limitations  set forth in Section 4(b). On
          the fourth (4th) Business Day after the Redemption Notice, the Company
          shall deliver to the Holder the Company  Additional  Redemption Amount
          with respect to the Principal  amount  redeemed after giving effect to
          conversions effected during the three (3) Business Day period.

(4)  CONVERSION OF DEBENTURE. This Debenture shall be convertible into shares of
     the Company's  Common Stock,  on the terms and conditions set forth in this
     Section 4.

     (a)  Conversion  Right.  Subject to the  provisions of Section 4(c), at any
          time or times on or after  the  Issuance  Date,  the  Holder  shall be
          entitled  to  convert  any  portion  of  the  outstanding  and  unpaid
          Conversion Amount (as defined below) into fully paid and nonassessable
          shares  of  Common  Stock in  accordance  with  Section  4(b),  at the
          Conversion  Rate (as  defined  below).  The number of shares of Common
          Stock issuable upon  conversion of any Conversion  Amount  pursuant to
          this Section 4(a) shall be determined by dividing (x) such  Conversion
          Amount  by (y) the  Conversion  Price  (the  "Conversion  Rate").  The
          Company  shall not issue any  fraction of a share of Common Stock upon
          any  conversion.  If the  issuance  would  result in the issuance of a
          fraction  of a share of Common  Stock,  the  Company  shall round such
          fraction of a share of Common Stock up to the nearest whole share. The
          Company shall pay any and all  transfer,  stamp and similar taxes that
          may be payable  with  respect to the  issuance  and delivery of Common
          Stock upon conversion of any Conversion Amount.

          (i)  "Conversion  Amount"  means  the  portion  of the  Principal  and
               accrued  Interest to be  converted,  redeemed or  otherwise  with
               respect to which this determination is being made.

          (ii) "Conversion  Price" means,  as of any Conversion Date (as defined
               below) the lesser of (a) $0.05 (the "Fixed Conversion  Price") or
               (b) eighty  percent (80%) of the lowest  Closing Bid Price of the
               Common  Stock  during the thirty (30)  trading  days  immediately
               preceding the Conversion Date as quoted by Bloomberg (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
               terms of this Debenture.

     (b)  Mechanics of Conversion.

          (i)  Optional Conversion. To convert any Conversion Amount into shares
               of Common  Stock on any date (a  "Conversion  Date"),  the Holder
               shall (A)  transmit by  facsimile  (or  otherwise  deliver),  for
               receipt on or prior to 11:59 p.m., New York Time, on such date, a
               copy of an executed  notice of  conversion  in the form  attached
               hereto as Exhibit I (the "Conversion  Notice") to the Company and
               (B) if required by Section 4(b)(iv),  surrender this Debenture to
               a nationally  recognized  overnight delivery service for delivery
               to the  Company  (or an  indemnification  undertaking  reasonably
               satisfactory to the Company with respect to this Debenture in the
               case of its loss, theft or  destruction).  On or before the third
               Business Day following the date of receipt of a Conversion Notice
               (the "Share Delivery Date"), the Company shall (X) if legends are
               not  required to be placed on  certificates  of Common  Stock and
               provided  that  the  Transfer  Agent  is   participating  in  the
               Depository  Trust  Company's  ("DTC") Fast  Automated  Securities
               Transfer  Program,  credit  such  aggregate  number  of shares of
               Common  Stock to  which  the  Holder  shall  be  entitled  to the
               Holder's or its designee's  balance  account with DTC through its
               Deposit Withdrawal Agent Commission system or (Y) if the Transfer
               Agent is not  participating in the DTC Fast Automated  Securities
               Transfer  Program,  issue and deliver to the address as specified
               in the Conversion  Notice, a certificate,  registered in the name
               of the Holder or its designee, for the number of shares of Common
               Stock to which the Holder  shall be entitled  which  certificates
               shall not bear any  restrictive  legends.  If this  Debenture  is
               physically   surrendered   for  conversion  and  the  outstanding
               Principal of this Debenture is greater than the Principal portion
               of the Conversion Amount being converted,  then the Company shall
               as soon as  practicable  and in no event  later  than  three  (3)
               Business  Days  after  receipt of this  Debenture  and at its own
               expense,  issue  and  deliver  to  the  holder  a  new  Debenture
               representing the outstanding Principal not converted.  The Person
               or  Persons  entitled  to  receive  the  shares of  Common  Stock
               issuable upon a conversion of this Debenture shall be treated for
               all  purposes  as the record  holder or holders of such shares of
               Common Stock upon the transmission of a Conversion Notice.

          (ii) Company's Failure to Timely Convert.  If within three (3) Trading
               Days  after the  Company's  receipt  of the  facsimile  copy of a
               Conversion  Notice the Company  shall fail to issue and deliver a
               certificate to the Holder or credit the Holder's  balance account
               with DTC for the  number of  shares of Common  Stock to which the
               Holder  is  entitled  upon  such   holder's   conversion  of  any
               Conversion  Amount (a "Conversion  Failure"),  and if on or after
               such  Trading  Day  the  Holder  purchases  (in  an  open  market
               transaction or otherwise) Common Stock to deliver in satisfaction
               of a sale by the  Holder  of  Common  Stock  issuable  upon  such
               conversion that the Holder anticipated receiving from the Company
               (a "Buy-In"),  then the Company shall,  within three (3) Business
               Days after the Holder's  request and in the Holder's  discretion,
               either  (i) pay  cash to the  Holder  in an  amount  equal to the
               Holder's total purchase price  (including  brokerage  commissions
               and  other  out of  pocket  expenses,  if any) for the  shares of
               Common Stock so purchased  (the "Buy-In  Price"),  at which point
               the  Company's  obligation  to deliver such  certificate  (and to
               issue such Common Stock) shall terminate,  or (ii) promptly honor
               its  obligation  to  deliver  to  the  Holder  a  certificate  or
               certificates  representing  such Common Stock and pay cash to the
               Holder in an amount  equal to the  excess  (if any) of the Buy-In
               Price  over the  product  of (A) such  number of shares of Common
               Stock, times (B) the Closing Bid Price on the Conversion Date.

          (iii) Book-Entry.  Notwithstanding  anything to the contrary set forth
               herein,  upon  conversion  of any  portion of this  Debenture  in
               accordance  with  the  terms  hereof,  the  Holder  shall  not be
               required to physically  surrender  this  Debenture to the Company
               unless  (A)  the  full  Conversion  Amount  represented  by  this
               Debenture  is being  converted or (B) the Holder has provided the
               Company with prior  written  notice (which notice may be included
               in a Conversion Notice)  requesting  reissuance of this Debenture
               upon  physical  surrender of this  Debenture.  The Holder and the
               Company shall maintain records showing the Principal and Interest
               converted  and the  dates of such  conversions  or shall use such
               other  method,  reasonably  satisfactory  to the  Holder  and the
               Company,  so  as  not  to  require  physical  surrender  of  this
               Debenture upon conversion.

     (c)  Limitations on Conversions.

          (i)  Beneficial   Ownership.   The   Company   shall  not  effect  any
               conversions  of this  Debenture and the Holder shall not have the
               right to convert any portion of this  Debenture or receive shares
               of Common  Stock as payment of interest  hereunder  to the extent
               that after giving  effect to such  conversion  or receipt of such
               interest  payment,  the  Holder,   together  with  any  affiliate
               thereof, would beneficially own (as determined in accordance with
               Section  13(d)  of the  Exchange  Act and the  rules  promulgated
               thereunder)  in excess of 9.99% of the number of shares of Common
               Stock  outstanding   immediately  after  giving  effect  to  such
               conversion or receipt of shares as payment of interest. Since the
               Holder will not be  obligated to report to the Company 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 4.99% 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
               Company  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 Section 4(a)
               and, any principal  amount  tendered for  conversion in excess of
               the permitted  amount  hereunder shall remain  outstanding  under
               this Debenture. 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 Company.  Other Holders
               shall be unaffected by any such waiver.

     (d)  Other Provisions.

               (i)  The Company  shall at all times  reserve and keep  available
                    out of its authorized Common Stock the full number of shares
                    of Common Stock issuable upon  conversion of all outstanding
                    amounts under this Debenture;  and within three (3) Business
                    Days  following  the  receipt  by the  Company of a Holder's
                    notice that such minimum number of Underlying  Shares is not
                    so reserved, the Company shall promptly reserve a sufficient
                    number  of  shares  of  Common  Stock to  comply  with  such
                    requirement.

               (ii) All  calculations  under this  Section 4 shall be rounded to
                    the nearest $0.0001 or whole share.

               (iii) 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 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 Company as to reservation of
                    such shares set forth in this Debenture) be issuable (taking
                    into  account the  adjustments  and  restrictions  set forth
                    herein) upon the  conversion  of the  outstanding  principal
                    amount of this Debenture and payment of interest  hereunder.
                    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, and nonassessable.

               (iv) 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  Company  '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.

(5)  Adjustments to Conversion Price

     (a)  Adjustment of Conversion  Price upon Issuance of Common Stock.  If the
          Company,  at any time while this Debenture is  outstanding,  issues or
          sells,  or in  accordance  with  this  Section  5(a) is deemed to have
          issued or sold, any shares of Common Stock, excluding shares of Common
          Stock deemed to have been issued or sold by the Company in  connection
          with any Excluded Securities,  for a consideration per share (the "New
          Issuance  Price") less than a price equal to the  Conversion  Price in
          effect  immediately  prior  to such  issue  or sale  (such  price  the
          "Applicable  Price")  (the  foregoing  a  "Dilutive  Issuance"),  then
          immediately  after such Dilutive Issuance the Conversion Price then in
          effect shall be reduced to an amount equal to the New Issuance  Price.
          For purposes of determining the adjusted  Conversion  Price under this
          Section 5(a), the following shall be applicable:

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

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

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

          (iv) Calculation  of  Consideration  Received.  In case any  Option is
               issued in connection  with the issue or sale of other  securities
               of the Company, together comprising one integrated transaction in
               which no specific  consideration  is allocated to such Options by
               the  parties  thereto,  the  Options  will be deemed to have been
               issued for the  difference of (x) the aggregate fair market value
               of such  Options  and  other  securities  issued  or sold in such
               integrated  transaction,  less (y) the fair  market  value of the
               securities  other  than  such  Option,  issued  or  sold  in such
               transaction  and  the  other  securities  issued  or sold in such
               integrated transaction will be deemed to have been issued or sold
               for the balance of the consideration  received by the Company. If
               any Common Stock, Options or Convertible Securities are issued or
               sold or  deemed  to  have  been  issued  or sold  for  cash,  the
               consideration  received  therefor  will be deemed to be the gross
               amount raised by the Company; provided,  however, that such gross
               amount is not greater than 110% of the net amount received by the
               Company  therefor.  If any Common Stock,  Options or  Convertible
               Securities  are  issued or sold for a  consideration  other  than
               cash, the amount of the consideration other than cash received by
               the Company will be the fair value of such consideration,  except
               where such  consideration  consists of securities,  in which case
               the amount of  consideration  received by the Company will be the
               Closing Bid Price of such  securities on the date of receipt.  If
               any Common Stock, Options or Convertible Securities are issued to
               the owners of the  non-surviving  entity in  connection  with any
               merger in which the Company is the surviving  entity,  the amount
               of consideration  therefor will be deemed to be the fair value of
               such portion of the net assets and business of the  non-surviving
               entity  as is  attributable  to such  Common  Stock,  Options  or
               Convertible Securities, as the case may be. The fair value of any
               consideration  other than cash or  securities  will be determined
               jointly by the Company and the Holder. If such parties are unable
               to reach  agreement  within ten (10) days after the occurrence of
               an event requiring  valuation (the "Valuation  Event"),  the fair
               value of such  consideration  will be determined  within five (5)
               Business  Days after the tenth (10th) day following the Valuation
               Event by an independent,  reputable appraiser jointly selected by
               the Company and the Holder.  The  determination of such appraiser
               shall be deemed  binding upon all parties  absent  manifest error
               and the fees and expenses of such appraiser shall be borne by the
               Company.

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

     (b)  Adjustment of Conversion  Price upon  Subdivision  or  Combination  of
          Common  Stock.  If the  Company,  at any time 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 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  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.

     (c)  Purchase  Rights.  If at any time the Company grants,  issues or sells
          any  Options,  Convertible  Securities  or rights to  purchase  stock,
          warrants,  securities or other property pro rata to the record holders
          of any class of Common Stock (the "Purchase Rights"),  then the Holder
          will be  entitled  to  acquire,  upon  the  terms  applicable  to such
          Purchase Rights,  the aggregate Purchase Rights which the Holder could
          have  acquired  if the  Holder had held the number of shares of Common
          Stock acquirable upon complete  conversion of this Debenture  (without
          taking  into  account  any   limitations   or   restrictions   on  the
          convertibility of this Debenture) immediately before the date on which
          a record is taken for the  grant,  issuance  or sale of such  Purchase
          Rights,  or,  if no such  record  is  taken,  the date as of which the
          record  holders of Common  Stock are to be  determined  for the grant,
          issue or sale of such Purchase Rights.

     (d)  Other  Events.  If any event  occurs of the type  contemplated  by the
          provisions  of this Section 4 but not  expressly  provided for by such
          provisions  (including,  without  limitation,  the  granting  of stock
          appreciation rights,  phantom stock rights or other rights with equity
          features),  then  the  Company's  Board  of  Directors  will  make  an
          appropriate  adjustment in the  Conversion  Price so as to protect the
          rights of the  Holder  under  this  Debenture;  provided  that no such
          adjustment will increase the Conversion Price as otherwise  determined
          pursuant to this Section 5.

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

     (f)  Whenever  the  Conversion  Price is  adjusted  pursuant  to  Section 5
          hereof, the Company 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.

     (g)  In case of any (1)  merger  or  consolidation  of the  Company  or any
          subsidiary of the Company with or into another Person,  or (2) sale by
          the Company or any  subsidiary of the Company of more than one-half of
          the assets of the Company 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 Debenture was 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.

          or  redemption  of any  portion  of this  Debenture,  the  outstanding

          exchangeable, upon the surrender hereof by the Holder at the principal
          office of the Company, for a new Debenture (in accordance with Section
          6(d)) representing in the aggregate the outstanding  Principal of this
          Debenture,  and each such new Debenture will represent such portion of
          such outstanding  Principal as is designated by the Holder at the time
          of such surrender.

     (d)  Issuance of New Debentures.  Whenever the Company is required to issue
          a new  Debenture  pursuant  to the terms of this  Debenture,  such new
          Debenture (i) shall be of like tenor with this  Debenture,  (ii) shall
          represent,  as  indicated  on the  face of  such  new  Debenture,  the
          Principal  remaining  outstanding  (or in the case of a new  Debenture
          being issued  pursuant to Section 6(a) or Section 6(c),  the Principal
          designated  by  the  Holder   which,   when  added  to  the  principal
          represented by the other new Debentures issued in connection with such
          issuance,  does not exceed the Principal  remaining  outstanding under
          this Debenture  immediately prior to such issuance of new Debentures),
          (iii) shall have an issuance  date,  as  indicated on the face of such
          new  Debenture,  which  is the  same  as the  Issuance  Date  of  this
          Debenture,  (iv) shall have the same  rights  and  conditions  as this
          Debenture,  and (v) shall  represent  accrued and unpaid Interest from

     on,  this  Debenture  at the  time,  place,  and  rate,  and in the coin or
     currency,  herein prescribed.  This Debenture is a direct obligation of the
     Company.  As long as this Debenture is  outstanding,  the Company shall not
     and shall  cause  their  subsidiaries  not to,  without  the consent of the
     Holder, (i) amend its certificate of incorporation, bylaws or other charter
     documents so as to adversely  affect any rights of the Holder;  (ii) repay,
     repurchase or offer to repay, repurchase or otherwise acquire shares of its
     Common Stock or other  equity  securities  other than as to the  Underlying
     Shares to the extent  permitted or required under this Debenture;  or (iii)
     enter into any agreement with respect to any of the foregoing.

(9)  This  Debenture  shall not  entitle  the  Holder to any of the  rights of a
     stockholder  of the Company,  including  without  limitation,  the right to
     vote,  to receive  dividends  and other  distributions,  or to receive  any
     notice of, or to attend,  meetings of stockholders or any other proceedings
     of the Company,  unless and to the extent  converted  into shares of Common
     Stock in accordance with the terms hereof.

(10) No  indebtedness  of the  Company is senior to this  Debenture  in right of
     payment,  whether with respect to interest,  damages or upon liquidation or
     dissolution or otherwise.  Without the Holder's  consent,  the Company will
     not  and  will  not  permit  any of  their  subsidiaries  to,  directly  or
     indirectly,  enter  into,  create,  incur,  assume  or  suffer to exist any
     indebtedness  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  there  from  that  is  senior  in any  respect  to the
     obligations of the Company under this Debenture.

(11) This  Debenture  shall be governed by and construed in accordance  with the
     laws of the State of New Jersey, without giving effect to conflicts of laws
     thereof.  Each of the parties  consents to the jurisdiction of the Superior
     Courts of the State of New Jersey sitting in Hudson County,  New Jersey and
     the U.S.  District  Court for the District of New Jersey sitting in Newark,
     New Jersey in connection  with any dispute arising under this Debenture and
     hereby  waives,  to the maximum  extent  permitted by law,  any  objection,
     including  any objection  based on forum non  conveniens to the bringing of
     any such proceeding in such jurisdictions.

(12) If the Company fails to strictly  comply with the terms of this  Debenture,
     then the Company shall  reimburse the Holder  promptly for all fees,  costs
     and expenses,  including, without limitation,  attorneys' fees and expenses
     incurred  by the Holder in any action in  connection  with this  Debenture,
     including,  without  limitation,  those  incurred:  (i) during any workout,
     attempted workout,  and/or in connection with the rendering of legal advice
     as to the Holder's rights,  remedies and  obligations,  (ii) collecting any
     sums which become due to the Holder,  (iii)  defending or  prosecuting  any
     proceeding or any  counterclaim  to any  proceeding or appeal;  or (iv) the
     protection,  preservation  or  enforcement of any rights or remedies of the
     Holder.

(13) Any waiver by 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 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.

(14) 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  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 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 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.

(15) 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.

(16) 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 DEBENTURE OR ANY
     COURSE  OF  CONDUCT,  COURSE  OF  DEALING,  STATEMENTS  (WHETHER  VERBAL OR
     WRITTEN) OR ACTIONS OF ANY PARTY.  THIS PROVISION IS A MATERIAL  INDUCEMENT
