     4. Prepayment; Repayment Upon Consolidation or Merger. The principal amount

corporation.

and at any time on or prior to the Maturity  Date, to convert all or any part of
the entirety of the debt then  outstanding  under this Note into  fully-paid and
non-assessable  shares of Common Stock,  or any shares of capital stock or other
securities  of the Company  into which such  Common  Stock  shall  hereafter  be

Securities Purchase Agreement.

                                       2

and security interests with respect to the issue thereof.

          the  appointment  of a receiver,  trustee,  custodian or other similar
          official for it or for any  substantial  part of its  property)  shall
          occur; or

               (vi) The  occurrence  of any  event  of  default  or other  event
          triggering  acceleration of any  indebtedness by the Company under any

          indebtedness  (but not  including any trade  payables  incurred in the
          ordinary course of business),  whether such indebtedness now exists or

          which shall remain unsatisfied,  unvacated, unhanded or unstayed until
          the date that is the  earlier to occur of thirty  (30) days after such

               (x) The Company  shall  challenge,  or  institute  or join in any
          proceedings   to   challenge   the   validity,   binding   effect   or
          enforceability  of this  Note or any  endorsement  of this Note or any
          other obligation to Holder; or

               (xi) The Security  Agreement or any provision thereof shall cease
          to be in full force or effect or shall be  declared to be null or void
          or otherwise  unenforceable  in whole or in part;  or Holder shall not
          have or shall cease to have a valid and perfected security interest in
          the collateral described in the Security Agreement; or

               (xii) The  removal  of the Lead  Lender  Director  for any reason
          without the approval of St. Cloud.

          (b) In the event of and immediately upon the occurrence of an Event of
     Default,  the Note shall  become  immediately  due and payable  without any
     action by the Holder and the Note  shall  bear  interest  until paid at the
     rate of 15% per annum (the "Default Interest Rate"). If an Event of Default
     occurs and is continuing,  Holder may pursue any remedy available at law or
     in equity or  provided  for in any Loan  Document to collect the payment of
     all  amounts  due  under  the Note or to  enforce  the  performance  of any
     provision of the Note,  and all expenses  incurred by Holder in  connection
     with any  remedy  shall be  deemed  indebtedness  of the  Company.  For the
     avoidance of doubt,  the  occurrence of an Event of Default as set forth in
     Section 6(a)(iv) and Section 6(a)(v) above shall make all sums of principal
     and interest then remaining unpaid and all other amounts payable hereon due
     and payable,  all without demand,  presentment,  notice or protest,  all of
     which hereby are expressly  waived,  and will permit Holder to exercise any
     other  right  available  to it at law or in  equity,  all which  rights and
     powers may be exercised cumulatively.  No delay or failure of Holder in the
     exercise of any right or remedy  provided  for under this Note or under any
     of the Loan Documents shall be deemed a waiver of such right by Holder.  No
     exercise  or  partial  exercise  or waiver of any right or remedy  shall be
     deemed a waiver of any  further  exercise of such right or remedy or of any
     other  right or remedy that Holder may have under this Note or under any of
     the  Loan  Documents.  Enforcement  of any  of  Holder's  rights  as to any
     security for the Promissory Note shall not affect Holder's right to enforce
     payment of the  Promissory  Note and to recover  judgment  for any  portion
     thereof  remaining  unpaid.  The rights and remedies set forth in this Note
     and in any of the Loan  Documents are  cumulative  and not exclusive of any
     other right or remedy that Holder may have.

          (c) In no event shall  Holder be entitled  to interest  exceeding  the
     maximum  rate  permitted  by  law  or  under  the  applicable   regulations
     promulgated by the United States Small Business Administration (the "SBA").
     If any excess  interest is provided  for or shall be  adjudicated  to be so
     provided for in this Note, or if any payment or other  consideration  under
     this Note or the Securities  Purchase Agreement is determined by the SBA to
     exceed the amount permitted under applicable regulations promulgated by the
     SBA, then in such event:  (i) the provisions of this paragraph shall govern
     and control;  (ii) the Company  shall not be obligated to pay the amount of
     such interest or other payment or consideration to the extent that it is in
     excess  of the  maximum  amount  permitted  by law,  and the same  shall be
     construed  as a mutual  mistake of the  parties;  and (iii) any such excess
     which may have been collected or attributed shall, at the option of Holder,
     be subtracted from the then unpaid  principal  amount hereof or refunded to
     the Company.

                                       5



     7.  Failure to Pay Upon  Maturity.  In the event that the sum due under the
Note is not repaid on the  Maturity  Date,  the  Holder  will have the option to
either have the Note accrue interest at the Default Interest Rate or such amount
as legally  allowed  until  paid,  or to convert  the  entirety of the debt then
outstanding  under the Note into the shares of Common Stock at the a price equal
to $.05 per share.  Such conversion  price in the event of default is subject to
adjustment pursuant to the terms of the Securities Purchase Agreement.

     8. Unconditional Obligation; Fees, Waivers, Other.

          (a) The obligations to make the payments provided for in this Note are
     absolute  and  unconditional  and  not  subject  to any  defense,  set-off,
     counterclaim, rescission, recoupment or adjustment whatsoever.

          (b) The  Company  promises  to pay all costs and  expenses,  including
     reasonable  attorneys'  fees,  all as provided in the  Securities  Purchase
     Agreement,  incurred in the collection and  enforcement of this Note and to
     indemnify  Holder against any losses,  claims,  damages and liabilities and
     related expenses,  including counsel fees and expenses,  incurred by Holder
     in connection with the collection and enforcement of this Note  (including,
     without  limitation,   in  connection  with  any  bankruptcy,   insolvency,
     reorganization or workout). In addition,  the Company agrees to pay, and to
     save Holder harmless from all liability for, any stamp or other documentary
     taxes which may be payable in connection  with the  Company's  execution or
     delivery of this Note.

          All  payments  made by the Company  under this Note shall be made free
     and clear of, and without  deduction or  withholding  for or on account of,
     any  present  or future  income,  stamp or other  taxes,  levies,  imposts,
     duties,  charges,  fees,  deductions  or  withholdings,  now  or  hereafter
     imposed,  levied,  collected,  withheld  or  assessed  by any  governmental
     authority,  excluding net income taxes and franchise taxes (imposed in lieu
     of net income  taxes)  imposed on Holder as a result of a present or former
     connection   between  Holder  and  the  jurisdiction  of  the  governmental
     authority  imposing  such  tax  or  any  political  subdivision  or  taxing
     authority thereof or therein (other than any such connection arising solely
     from Holder  having  executed,  delivered or performed its  obligations  or
     received a payment under, or enforced, this Note). If any such non-excluded
     taxes, levies,  imposts,  duties,  charges, fees deductions or withholdings
     ("Non-Excluded Taxes") are required to be withheld from any amounts payable
     to Holder  under this  Note,  the  amounts  so  payable to Holder  shall be
     increased to the extent  necessary to yield to Holder (after payment of all
     Non-Excluded Taxes) interest or any such other amounts payable hereunder at
     the  rates  or  in  the  amounts  specified  in  this  Note.  Whenever  any
     Non-Excluded  Taxes are  payable by the  Company,  as  promptly as possible
     thereafter  (and, in any event,  within five (5) business days) the Company
     shall send to Holder for its own  account a  certified  copy of an original
     official receipt  received by the Company showing payment  thereof.  If the
     Company  fails to pay any  Non-Excluded  Taxes when due to the  appropriate
     taxing authority or fails to remit to Holder the required receipts or other
     required documentary evidence, the Company shall indemnify, defend and hold
     Holder harmless for any incremental  taxes,  interest or penalties that may
     become payable by Holder as a result of any such failure.

          (c) No forbearance, indulgence, delay or failure to exercise any right
     or remedy  with  respect  to this Note  shall  operate as a waiver or as an
     acquiescence  in any default,  nor shall any single or partial  exercise of

                                       6



     any right or remedy preclude any other or further  exercise  thereof or the
     exercise of any other right or remedy.

          (d) This Note may not be modified or discharged (other than by payment
     or conversion) except in a writing duly executed by the Company and Holder.

          (e) Holder hereby expressly waives demand and presentment for payment,
     notice of  nonpayment,  notice of  dishonor,  protest,  notice of  protest,
     bringing of suit,  and  diligence  in taking any action to collect  amounts
     called for  hereunder,  and shall be directly and primarily  liable for the
     payment of all sums owing and to be owing hereon, regardless of and without
     any notice,  diligence,  act or omission with respect to the  collection of
     any amount  called for  hereunder or in  connection  with any right,  lien,
     interest  or  property  at any and all times  which the  Company  had or is
     existing as security for any amount called for hereunder.
