          be the date  that  such  Notice  of  Conversion  is  deemed  delivered
          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.
          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(s) converted and the date of such
          conversion(s).  The Company may deliver an  objection to any Notice of
          Conversion  within  1  Business  Day of  delivery  of such  Notice  of
          Conversion. 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 $0.45  subject  to  adjustment  herein  (the
          "Conversion Price").

                                       6

     c)   Holder's  Restriction on Conversion.  The Company shall not effect any
          conversion of this Debenture, and a Holder shall not have the right to
          convert any portion of this Debenture, to the extent that after giving
          effect  to the  conversion  set  forth  on the  applicable  Notice  of
          Conversion,  such Holder (together with such Holder's Affiliates,  and
          any other person or entity acting as a group together with such Holder
          or any of such Holder's  Affiliates) would  beneficially own in excess
          of  the  Beneficial  Ownership  Limitation  (as  defined  below).  For
          purposes  of the  foregoing  sentence,  the number of shares of Common
          Stock  beneficially  owned by such  Holder  and its  Affiliates  shall
          include the number of shares of Common Stock issuable upon  conversion
          of this  Debenture with respect to which such  determination  is being
          made, but shall exclude the number of shares of Common Stock which are
          issuable upon (A) conversion of the remaining,  unconverted  principal
          amount of this Debenture  beneficially  owned by such Holder or any of
          its  Affiliates  and (B) exercise or conversion of the  unexercised or
          unconverted  portion of any other securities of the Company subject to
          a limitation  on conversion  or exercise  analogous to the  limitation
          contained herein (including,  without limitation, any other Debentures
          or the  Warrants)  beneficially  owned  by such  Holder  or any of its
          Affiliates.  Except  as set  forth  in  the  preceding  sentence,  for
          purposes  of  this  Section  4(c),   beneficial   ownership  shall  be
          calculated  in  accordance  with Section 13(d) of the Exchange Act and
          the rules and regulations promulgated  thereunder.  To the extent that
          the   limitation   contained  in  this  Section  4(c)   applies,   the
          determination of whether this Debenture is convertible (in relation to
          other  securities  owned by such Holder  together with any Affiliates)
          and of which principal  amount of this Debenture is convertible  shall
          be in the sole  discretion  of such Holder,  and the  submission  of a
          Notice of Conversion shall be deemed to be such Holder's determination
          of whether  this  Debenture  may be  converted  (in  relation to other
          securities  owned by such Holder  together  with any  Affiliates)  and
          which principal amount of this Debenture is convertible,  in each case
          subject to such aggregate percentage limitations. To ensure compliance
          with this restriction,  each Holder will be deemed to represent to the
          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),  in  determining  the number of  outstanding  shares of
          Common Stock, a Holder may rely on the number of outstanding shares of
          Common  Stock as stated in the most recent of the  following:  (A) the
          Company's most recent Form 10-QSB or Form 10-KSB,  as the case may be;
          (B) a more recent public  announcement  by the Company;  or (C) a more
          recent 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 a Holder,  the  Company  shall  within two
          Trading Days  confirm  orally and in writing to such Holder the number
          of shares of Common Stock then outstanding. In any case, the number of
          outstanding  shares of Common Stock shall be  determined  after giving
          effect to the  conversion  or exercise of  securities  of the Company,
          including this Debenture,  by such Holder or its Affiliates  since the
          date as of which such number of outstanding shares of Common Stock was
          reported.  The "Beneficial Ownership Limitation" shall be 4.99% of the
          number of shares of the Common  Stock  outstanding  immediately  after
          giving effect to the issuance of shares of Common Stock  issuable upon
          conversion  of this  Debenture  held  by the  Holder.  The  Beneficial
          Ownership Limitation  provisions of this Section 4(c) may be waived by
          such Holder,  at the  election of such  Holder,  upon not less than 61
          days' prior notice to the Company, to change the Beneficial  Ownership
          Limitation  to 9.99% of the  number  of  shares  of the  Common  Stock
          outstanding  immediately after giving effect to the issuance of shares
          of Common Stock upon  conversion of this  Debenture held by the Holder
          and the provisions of this Section 4(c) shall continue to apply.  Upon
          such a change by a Holder of the Beneficial  Ownership Limitation from
          such  4.99%  limitation  to  such  9.99%  limitation,  the  Beneficial
          Ownership  Limitation  may not be further  waived by such Holder.  The
          provisions of this paragraph  shall be construed and  implemented in a
          manner  otherwise  than in  strict  conformity  with the terms of this
          Section 4(c) to correct this  paragraph (or any portion  hereof) which
          may  be  defective  or  inconsistent  with  the  intended   Beneficial
          Ownership   Limitation   herein   contained  or  to  make  changes  or
          supplements  necessary or  desirable  to properly  give effect to such
          limitation. The limitations contained in this paragraph shall apply to
          a successor holder of this Debenture.

                                       7

     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. 21


          ii.  Delivery of  Certificate  Upon  Conversion.  Not later than three
               Trading  Days after each  Conversion  Date (the  "Share  Delivery
               Date"), the Company shall deliver,  or cause to be delivered,  to
               the  Holder  a  certificate  or  certificates   representing  the
               Conversion  Shares which,  on or after the Effective  Date or the
               date when the conversion  Shares are eligible for sale under Rule
               144,   shall  be  free  of   restrictive   legends   and  trading
               restrictions  (other than those which may then be required by the
               Purchase  Agreement)  representing the number of shares of Common
               Stock being acquired upon the conversion of this Debenture. On or
               after the Effective  Date, the Company shall use its best efforts
               to  deliver  any  certificate  or  certificates  required  to  be
               delivered  by the  Company  under this  Section 4  electronically
               through  the  Depository  Trust  Company 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 the Conversion  Date, the Holder shall be entitled to elect
               by  written  notice to the  Company  at any time on or before its
               receipt of such  certificate  or  certificates,  to rescind  such
               Conversion,  in which event the Company shall promptly  return to
               the Holder any  original  Debenture  delivered to the Company and
               the Holder shall  promptly  return the Common Stock  certificates
               representing the principal amount of this Debenture  tendered for
               conversion to the Company.

          iv.  Obligation  Absolute;  Partial Liquidated Damages.  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,
               that 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
               anyone  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  to  Holder,
               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  outstanding  principal  amount of this Debenture,
               which is subject to the  injunction,  which bond shall  remain in
               effect  until the  completion  of  arbitration/litigation  of the
               underlying  dispute and the proceeds of which shall be payable to
               such Holder to the extent it obtains judgment.  In the absence of
               such injunction, the Company shall issue Conversion Shares or, if
               applicable,  cash,  upon a properly  noticed  conversion.  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,  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 on the fifth
               Trading Day after such  liquidated  damages  begin to accrue) for
               each  Trading  Day  after  such  third  Trading  Day  until  such
               certificates are delivered. Nothing herein shall limit a Holder's
               right to pursue  actual  damages  or  declare an Event of Default
               pursuant to Section 8 hereof 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 hereunder, at law or in equity including,  without limitation,
               a decree of specific  performance  and/or injunctive  relief. The
               exercise of any such rights  shall not  prohibit  the Holder from
               seeking to enforce  damages  pursuant to any other Section hereof
               or under applicable law.

                                       8

          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  by the Share Delivery
               Date  pursuant  to  Section  4(d)(ii),  and if after  such  Share
               Delivery  Date the Holder is  required by its  brokerage  firm to
               purchase (in an open market  transaction  or  otherwise),  or the
               Holder's  brokerage  firm otherwise  purchases,  shares of Common
               Stock to deliver in  satisfaction of a sale by such Holder of the
               Conversion  Shares  which the Holder was entitled to receive upon
               the conversion relating to such Share Delivery Date (a "Buy-In"),
               then the  Company  shall (A) pay in cash to the Holder (in ------
               addition  to any other  remedies  available  to or elected by the
               Holder) the amount by which (x) the Holder's total purchase price
               (including  any  brokerage  commissions)  for the Common Stock so
               purchased  exceeds (y) the product of (1) the aggregate number of
               shares of Common  Stock that such Holder was  entitled to receive
               from the  conversion  at issue  multiplied by (2) the actual sale
               price  at which  the  sell  order  giving  rise to such  purchase
               obligation was executed (including any brokerage commissions) and
               (B) at the option of 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 if
               the Company had 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 (including any brokerage  commissions) giving rise to such
               purchase  obligation  was a total of $10,000  under clause (A) of
               the immediately preceding sentence, the 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 and, upon request of the Company,  evidence
               of the amount of such loss. Nothing herein shall limit a Holder's
               right to pursue any other remedies available to it hereunder,  at
               law or in  equity  including,  without  limitation,  a decree  of
               specific performance and/or injunctive relief with respect to the
               Company's  failure to timely  deliver  certificates  representing
               shares of Common  Stock  upon  conversion  of this  Debenture  as
               required pursuant to the terms hereof.

          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 for the
               sole purpose of issuance upon  conversion of this  Debenture 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 150% of the aggregate  number of
               shares of the  Common  Stock as shall  (subject  to the terms and
               conditions set forth in the Purchase  Agreement) be issuable 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 authorized,
               validly  issued,   fully  paid  and  nonassessable  and,  if  the
               Registration  Statement is then  effective  under the  Securities
               Act, shall be registered for public sale in accordance  with such
               Registration Statement.

                                       9

          vii. Fractional Shares. Upon a conversion  hereunder the Company shall
               not  be  required  to  issue  stock   certificates   representing
               fractions  of  shares  of  Common  Stock,  but  may if  otherwise
               permitted,  make a cash payment in respect of any final  fraction
               of a share based on the VWAP at such time. If the 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,
               1 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  certificates,  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  payable  in shares of Common
          Stock on  shares  of  Common  Stock or any  Common  Stock  Equivalents
          (which, for avoidance of doubt, shall not include any shares of Common
          Stock issued by the Company upon  conversion of the  Debentures);  (B)
          subdivides  outstanding shares of Common Stock into a larger number of
          shares;  (C)  combines  (including  by way of a reverse  stock  split)
          outstanding shares of Common Stock into a smaller number of shares; or
          (D) issues, in the event of a reclassification of shares of the Common
          Stock, any shares of capital stock of the 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 any treasury shares
          of the Company) 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, at any time  while this  Debenture  is
          outstanding,  the Company or any Subsidiary,  as applicable,  sells or
          grants any option to purchase or sells or grants any right to reprice,
          or otherwise  disposes of or issues (or announces  any sale,  grant or
          any option to  purchase  or other  disposition),  any Common  Stock or
          Common Stock  Equivalents  entitling  any Person to acquire  shares of
          Common  Stock at an  effective  price per share that is lower than the
          then Conversion Price (such lower price,  the "Base Conversion  Price"
          and such  issuances,  collectively,  a  "Dilutive  Issuance")  (if the
          holder of the Common Stock or Common Stock Equivalents so issued shall
          at any time, whether by operation of purchase price adjustments, reset
          provisions,  floating  conversion,  exercise  or  exchange  prices  or
          otherwise,  or due to warrants,  options or rights per share which are
          issued in connection with such issuance, be entitled to receive shares
          of Common Stock at an effective price per share that is lower than the
          Conversion  Price,  such issuance shall be deemed to have occurred for
          less than the Conversion Price on such date of the Dilutive Issuance),
          then  the  Conversion  Price  shall  be  reduced  to  equal  the  Base
          Conversion  Price.  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 1 Business Day  following  the issuance of any
          Common Stock or Common Stock Equivalents subject to this Section 5(b),
          indicating therein the applicable  issuance price, or applicable reset
          price, exchange price,  conversion price and other pricing terms (such
          notice,   the   "Dilutive   Issuance   Notice").   For   purposes   of
          clarification, whether or not the Company provides a Dilutive Issuance
          Notice  pursuant to this  Section  5(b),  upon the  occurrence  of any
          Dilutive  Issuance,  the  Holder is  entitled  to  receive a number of
          Conversion Shares based upon the Base Conversion Price on or after the
          date of such  Dilutive  Issuance,  regardless  of  whether  the Holder
          accurately  refers  to the  Base  Conversion  Price in the  Notice  of
          Conversion.

                                       10

     c)   Subsequent  Rights  Offerings.  If the Company,  at any time while the
          Debenture is outstanding,  shall issue rights,  options or warrants to
          all  holders of Common  Stock (and not to Holders)  entitling  them to
          subscribe for or purchase  shares of Common Stock at a price per share
          that is lower than the VWAP on the record date referenced  below, then
          the  Conversion  Price shall be  multiplied by a fraction of which the
          denominator  shall  be  the  number  of  shares  of the  Common  Stock
          outstanding  on the date of issuance  of such rights or warrants  plus
          the  number  of   additional   shares  of  Common  Stock  offered  for
          subscription  or  purchase,  and of which the  numerator  shall be the
          number  of  shares  of the  Common  Stock  outstanding  on the date of
          issuance of such rights or  warrants  plus the number of shares  which
          the aggregate  offering price of the total number of shares so offered
          (assuming delivery to the Company in full of all consideration payable
          upon exercise of such rights,  options or warrants)  would purchase at
          such VWAP.  Such  adjustment  shall be made  whenever  such  rights or
          warrants are issued, and shall become effective  immediately after the
          record date for the determination of stockholders  entitled to receive
          such rights, options or warrants.

     d)   Pro  Rata  Distributions.  If the  Company,  at any  time  while  this
          Debenture is  outstanding,  distributes to all holders of Common Stock
          (and not to the  Holders)  evidences  of its  indebtedness  or  assets
          (including cash and cash dividends) or rights or warrants to subscribe
          for or purchase any security (other than the Common Stock, which shall
          be  subject to Section  5(b)),  then in each such case the  Conversion
          Price shall be adjusted by multiplying such Conversion Price in effect
          immediately  prior to the  record  date  fixed  for  determination  of
          stockholders  entitled to receive such  distribution  by a fraction of
          which the  denominator  shall be the VWAP  determined as of the record
          date mentioned above, and of which the numerator shall be such VWAP on
          such record  date less the then fair market  value at such record date
          of  the  portion  of  such  assets  or  evidence  of  indebtedness  so
          distributed  applicable to 1 outstanding  share of the Common Stock as
          determined by the Board of Directors of the Company in good faith.  In
          either  case  the  adjustments  shall  be  described  in  a  statement
          delivered to the Holder  describing the portion of assets or evidences
          of indebtedness so distributed or such subscription  rights applicable
          to 1 share of Common Stock. Such adjustment shall be made whenever any
          such distribution is made and shall become effective immediately after
          the record date mentioned above.

     e)   Fundamental  Transaction.  If, at any time  while  this  Debenture  is
          outstanding,  (A) the Company effects any merger or  consolidation  of
          the Company with or into another  Person,  (B) the Company effects any
          sale of all or substantially all of its assets in one transaction or a
          series of related transactions, (C) any tender offer or exchange offer
          (whether by the 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 1 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 1
          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 Section 5(e) and insuring that
          this  Debenture (or any such  replacement  security) will be similarly
          adjusted upon any  subsequent  transaction  analogous to a Fundamental
          Transaction.

                                       11


     f)   Effective Date Adjustment. On the Effective Date, the Conversion Price
          shall be immediately and  permanently  adjusted to equal the lesser of
          (i) the then  Conversion  Price  and (ii)  80% of the  average  of the
          Closing  Prices  on the 10  Trading  Days  immediately  preceding  the
          Effective Date.

     g)   Registration  Failure  Adjustment.  Upon the  occurrence of any of the
          following events, the Conversion Price shall be adjusted as follows:

               (i)  if  the  initial  Registration   Statement  registering  all
          Registrable  Securities  is not  effective  on or before  February 20,
          2008, the then Conversion  Price applicable to an amount of Conversion
          Shares equal to the 144 Amount shall be  immediately  and  permanently
          adjusted to equal the lesser of (i) the then Conversion Price and (ii)
          80% of the  average  of the 3  lowest  Closing  Prices  during  the 10
          Trading Days immediately preceding February 20, 2008;

               (ii)  if  the  initial  Registration  Statement  registering  all
          Registrable  Securities  is not effective on or before April 20, 2008,
          the  Conversion  Price  applicable to an amount of  Conversion  Shares
          equal to the 144 Amount shall be immediately and permanently  adjusted
          to equal the lesser of (i) the then  Conversion  Price and (ii) 80% of
          the average of the 3 lowest  Closing Prices during the 10 Trading Days
          immediately preceding April 20, 2008;

               (iii)  if the  initial  Registration  Statement  registering  all
          Registrable  Securities  is not  effective on or before July 20, 2008,
          the  Conversion  Price  applicable to an amount of  Conversion  Shares
          equal to the 144 Amount shall be immediately and permanently  adjusted
          to equal the lesser of (i) the then  Conversion  Price and (ii) 80% of
          the average of the 3 lowest  Closing Prices during the 10 Trading Days
          immediately preceding July 20, 2008;

               (iv)  if  the  initial  Registration  Statement  registering  all
          Registrable Securities is not effective on or before October 20, 2008,
          the  Conversion  Price  applicable to an amount of  Conversion  Shares
          equal to the 144 Amount shall be immediately and permanently  adjusted
          to equal the  lesser of (i) the then  effective  Conversion  Price and
          (ii) 80% of the average of the 3 lowest  Closing  Prices during the 10
          Trading Days immediately preceding October 20, 2008; and

               (v)  if  the  initial  Registration   Statement  registering  all
          Registrable  Securities  is not  effective  on or before  February 20,
          2009,  the  Conversion  Price  shall be  immediately  and  permanently
          adjusted  to equal  the  lesser of (i) the then  effective  Conversion
          Price  and (ii) 80% of the  average  of the 3  lowest  Closing  Prices
          during the 10 Trading Days immediately preceding February 20, 2009.

     h)   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  any
          treasury shares of the Company) issued and outstanding.

     i)   Notice to the Holder.

          i.   Adjustment to Conversion Price.  Whenever the Conversion Price is
               adjusted pursuant to any provision 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
               enters into a Variable Rate Transaction,  despite the prohibition
               thereon in the Purchase Agreement, the Company shall be deemed to
               have  issued  Common  Stock or Common  Stock  Equivalents  at the
               lowest possible  conversion price at which such securities may be
               converted or exercised.

                                       12

          ii.  Notice to Allow  Conversion  by Holder.  If (A) the Company shall
               declare a dividend (or any other  distribution  in whatever form)
               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 of 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 or (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 delivered to
               the  Holder  at its  last  address  as it shall  appear  upon the
               Debenture  Register,  at  least  20  calendar  days  prior to the
               applicable  record or effective  date  hereinafter  specified,  a
               notice  stating (x) the date on which a record is to be taken for
               the purpose of such dividend, distribution, redemption, rights or
               warrants, or if a record is not to be taken, the date as of which
               the holders of the Common  Stock of record to be entitled to such
               dividend, distributions, redemption, rights or warrants are to be
               determined  or (y)  the  date  on  which  such  reclassification,
               consolidation,  merger,  sale,  transfer  or  share  exchange  is
               expected to become  effective or close,  and the date as of which
               it is expected  that  holders of the Common Stock of record shall
               be  entitled  to exchange  their  shares of the Common  Stock for
               securities,   cash  or  other  property   deliverable  upon  such
               reclassification,  consolidation, merger, sale, transfer or share
               exchange, provided that the failure to deliver such notice or any
               defect  therein or in the delivery  thereof  shall not affect the
               validity of the corporate action required to be specified in such
               notice.  The Holder is entitled to convert this Debenture  during
               the 20-day period  commencing on the date of such notice  through
               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 Effective  Date,  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  principal  amount of this  Debenture for
          cash in an amount equal to the Optional  Redemption Amount on the 30th
          Trading Day following the Optional  Redemption Notice Date (such date,
          the  "Optional  Redemption  Date" and such  redemption,  the "Optional
          Redemption"). The Optional Redemption Amount is payable in full on the
          Optional  Redemption  Date.  The  Company  may only effect an Optional
          Redemption  if each of the  Equity  Conditions  shall have been met on
          each  Trading  Day  during  the  period  commencing  on  the  Optional
          Redemption  Notice Date  through to the Optional  Redemption  Date and
          through and  including  the date  payment of the  Optional  Redemption
          Amount is actually made. If any of the Equity  Conditions  shall cease
          to be satisfied at any time during the 30 Trading Day period, then the
          Holder may elect to nullify the Optional  Redemption  Notice by notice
          to the Company  within 3 Trading Days after the first day on which any
          such  Equity  Condition  has not been  met  (provided  that  if,  by a
          provision of the  Transaction  Documents,  the Company is obligated to
          notify the Holder of the  non-existence of an Equity  Condition,  such
          notice  period shall be extended to the third Trading Day after proper
          notice from the Company) in which case the Optional  Redemption Notice
          shall be null and void,  ab initio.  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.

                                       13

     b)   Redemption Procedure. The payment of cash or issuance of Common Stock,
          as applicable,  pursuant to an Optional Redemption shall be payable on
          the Optional  Redemption  Date. If any portion of the payment pursuant
          to an  Optional  Redemption  shall not be paid by the  Company  by the
          applicable due date, interest shall accrue thereon at an interest rate
          equal to the lesser of 18% per annum or the maximum rate  permitted by
          applicable  law until  such  amount  is paid in full.  Notwithstanding
          anything  herein  contained  to the  contrary,  if any  portion of the
          Optional  Redemption Amount remains unpaid after such date, the Holder
          may  elect,  by  written  notice  to the  Company  given  at any  time
          thereafter,  to invalidate such Optional  Redemption,  ab initio, and,
          with  respect  to  the   Company's   failure  to  honor  the  Optional
          Redemption,  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  ratably  among the
          Holders of Debentures. 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 the
          delivery of a Notice of Conversion to the Company.

     Section 7.  Negative  Covenants.  As long as any portion of this  Debenture
remains outstanding,  unless Purchasers holding in the aggregate at least 75% of
the principal amount of the then outstanding  Debentures shall otherwise consent
in writing,  the Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly:

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

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

     c)   amend  its  charter  documents,  including,  without  limitation,  the
          certificate of incorporation and bylaws, in any manner that materially
          and adversely affects 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

               and such  judgment,  writ or similar  final  process shall remain

                                       16


     b)   Remedies Upon Event of Default.  If any Event of Default  occurs,  the
          outstanding principal amount of this Debenture, liquidated damages and
          other   amounts  owing  in  respect   thereof   through  the  date  of
          acceleration,  shall become, at the Holder's election, immediately due
          and payable in cash at 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 an interest rate equal to the lesser of 18%
          per annum or the maximum rate permitted under applicable law. Upon the
          payment in full of the  Mandatory  Default  Amount,  the Holder  shall
          promptly surrender this Debenture to or as directed by the Company. In
          connection with such acceleration  described  herein,  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  acceleration may be rescinded and annulled
          by Holder at any time prior to payment  hereunder and the Holder shall
          have all rights as a holder of the Debenture  until such time, if any,
          as the Holder receives full payment  pursuant to this Section 8(b). No
          such  rescission  or annulment  shall affect any  subsequent  Event of
          Default or impair any right consequent thereon.

     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 the  principles  of conflict of
          laws thereof. Each party agrees that all legal proceedings  concerning
          the  interpretation,  enforcement  and  defense  of  the  transactions
          contemplated  by any of the  Transaction  Documents  (whether  brought
          against  a  party  hereto  or its  respective  Affiliates,  directors,
          officers, shareholders, employees or agents) shall be commenced in the
          state and federal courts  sitting in the City of New York,  Borough of
          Manhattan   (the  "New  York   Courts").   Each  party  hereto  hereby
          irrevocably  submits  to the  exclusive  jurisdiction  of the New York
          Courts for the adjudication of any dispute  hereunder or in connection
          herewith  or with any  transaction  contemplated  hereby or  discussed
          herein  (including  with  respect  to  the  enforcement  of any of the
          Transaction Documents),  and hereby irrevocably waives, and agrees not
          to assert in any suit, action or proceeding,  any claim that it is not
          personally  subject to the  jurisdiction  of such New York Courts,  or
          such New York  Courts  are  improper  or  inconvenient  venue for such
          proceeding.  Each party hereby  irrevocably waives personal service of
          process and consents to process being served in any such suit,  action
          or  proceeding  by mailing a copy thereof via  registered or certified
          mail or overnight  delivery  (with evidence of delivery) to such party
          at the  address in effect for notices to it under this  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 other
          manner   permitted  by  applicable   law.  Each  party  hereto  hereby
          irrevocably waives, to the fullest extent permitted by applicable law,
          any and all right to trial by jury in any legal proceeding arising out
          of or  relating to this  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  in 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 by the
          Company or the Holder 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 the applicable law
          governing  usury,  the applicable rate of interest due hereunder shall
          automatically  be  lowered  to  equal  the  maximum  rate of  interest
          permitted under  applicable law. 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.

                                       19

     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 any surviving entity in a
          Fundamental  Transaction  shall (i) assume,  prior to such Fundamental
          Transaction,  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) and (ii) 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
          equal to the  principal  amount,  which shall be  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.

     j)   Secured  Obligation.   The  obligations  of  the  Company  under  this
          Debenture are secured by all assets of the Company and each Subsidiary
          pursuant to the  Security  Agreement,  dated as of February  20, 2007,
          between the Company,  [the Subsidiaries of the Company and the Secured
          Parties (as defined therein)
