Laurus (the  "Securities  Purchase  Agreement") and (ii) each Related  Agreement
referred  to in the  Securities  Purchase  Agreement  (the  Securities  Purchase
Agreement and each Related Agreement, as each may be amended, modified, restated
or supplemented  from time to time, are  collectively  referred to herein as the
"Documents"),  or  any  documents,  instruments  or  agreements  relating  to or
executed in  connection  with the  Documents or any  documents,  instruments  or
agreements  referred  to  therein  or  otherwise,  or  any  other  indebtedness,
obligations  or  liabilities  of the Debtor to Laurus,  whether now  existing or
hereafter arising, direct or indirect,  liquidated or unliquidated,  absolute or
contingent,  due or not due and whether  under,  pursuant to or  evidenced  by a
note,  agreement,  guaranty,  instrument  or otherwise  (all of which are herein
collectively  referred  to  as  the  "Obligations"),  and  irrespective  of  the
genuineness,  validity,  regularity or enforceability of such Obligations, or of
any instrument  evidencing any of the Obligations or of any collateral  therefor
or of the  existence  or  extent of such  collateral,  and  irrespective  of the
allowability,  allowance or disallowance of any or all of the Obligations in any
case  commenced  by or  against  Debtor  under  Title 11,  United  States  Code,
including,  without  limitation,  obligations  or  indebtedness  of  Debtor  for
post-petition interest,  fees, costs and charges that would have accrued or been
added to the  Obligations  but for the  commencement  of such  case.  Terms  not
otherwise  defined  herein  shall have the  meaning  assigned  such terms in the
Securities Purchase Agreement. In furtherance of the foregoing,  the undersigned
hereby agrees as follows:

      1. No  Impairment.  Laurus  may at any time and from time to time,  either
before or after the maturity  thereof,  without notice to or further  consent of
the  undersigned,  extend the time of payment  of,  exchange  or  surrender  any
collateral  for, renew or extend any of the  Obligations or increase or decrease
the interest rate thereon,  or any other agreement with Debtor or with any other
party to or person liable on any of the Obligations,  or interested therein, for
the extension,  renewal, payment,  compromise,  discharge or release thereof, in
whole or in part, or



for any modification of the terms thereof or of any agreement between Laurus and
Debtor or any such other party or person,  or make any election of rights Laurus
may deem desirable under the United States  Bankruptcy Code, as amended,  or any
other federal or state bankruptcy, reorganization,  moratorium or insolvency law
relating to or affecting the enforcement of creditors'  rights generally (any of
the foregoing,  an  "Insolvency  Law") without in any way impairing or affecting
this Guaranty.  This instrument shall be effective  regardless of the subsequent
incorporation,  merger  or  consolidation  of  Debtor,  or  any  change  in  the
composition,  nature,  personnel  or location of Debtor and shall  extend to any
successor  entity to Debtor,  including a debtor in possession or the like under
any Insolvency Law.

      2.  Guaranty  Absolute.  Each of the  undersigned  jointly  and  severally
guarantees  that the  Obligations  will be paid strictly in accordance  with the
terms of the  Documents  and/or  any other  document,  instrument  or  agreement
creating or evidencing  the  Obligations,  regardless of any law,  regulation or
order now or hereafter in effect in any jurisdiction affecting any of such terms
or the rights of Debtor with respect thereto. Guarantors hereby knowingly accept
the full range of risk  encompassed  within a contract of "continuing  guaranty"
which risk  includes  the  possibility  that  Debtor  will  contract  additional
indebtedness  for  which  Guarantors  may be  liable  hereunder  after  Debtor's
financial  condition  or ability to pay its lawful  debts when they fall due has
deteriorated,  whether or not  Debtor has  properly  authorized  incurring  such
additional   indebtedness.   The  undersigned   acknowledge  that  (i)  no  oral
representations, including any representations to extend credit or provide other
financial  accommodations  to  Debtor,  have been  made by Laurus to induce  the
undersigned  to enter into this Guaranty and (ii) any extension of credit to the
Debtor  shall  be  governed  solely  by the  provisions  of the  Documents.  The
liability of each of the  undersigned  under this Guaranty shall be absolute and
unconditional,  in accordance with its terms, and shall remain in full force and
effect  without  regard to, and shall not be  released,  suspended,  discharged,
terminated or otherwise affected by, any circumstance or occurrence  whatsoever,
including,  without limitation: (a) any waiver, indulgence,  renewal, extension,
amendment or modification  of or addition,  consent or supplement to or deletion
from or any other action or inaction under or in respect of the Documents or any
other instruments or agreements relating to the Obligations or any assignment or
transfer  of any  thereof,  (b) any lack of validity  or  enforceability  of any
Document  or  other  documents,   instruments  or  agreements  relating  to  the
Obligations or any assignment or transfer of any thereof,  (c) any furnishing of
any additional  security to Laurus or its assignees or any acceptance thereof or
any release of any security by Laurus or its  assignees,  (d) any  limitation on
any party's  liability or obligation under the Documents or any other documents,
instruments  or  agreements  relating to the  Obligations  or any  assignment or
transfer of any thereof or any  invalidity or  unenforceability,  in whole or in
part, of any such document, instrument or agreement or any term thereof, (e) any
bankruptcy, insolvency,  reorganization,  composition,  adjustment, dissolution,
liquidation  or other like  proceeding  relating to Debtor,  or any action taken
with respect to this  Guaranty by any trustee or receiver,  or by any court,  in
any such  proceeding,  whether  or not the  undersigned  shall  have  notice  or
knowledge of any of the foregoing, (f) any exchange, release or nonperfection of
any  collateral,  or any  release,  or  amendment  or  waiver of or  consent  to
departure  from any guaranty or security,  for all or any of the  Obligations or
(g) any other circumstance which might otherwise  constitute a defense available
to, or a discharge of, the undersigned.  Any amounts due from the undersigned to
Laurus  shall bear  interest  until such amounts are paid in full at the highest
rate then  applicable  to the  Obligations.  Obligations  include  post-petition
interest whether or not allowed or allowable.

      3. Waivers.
         --------

            (a) This  Guaranty is a guaranty  of payment and not of  collection.
      Laurus shall be under no obligation to institute suit,  exercise rights or
      remedies  or take any other  action  against  Debtor  or any other  person
      liable with respect to any of the  Obligations or resort to any collateral
      security  held  by it to  secure  any of the  Obligations  as a  condition
      precedent to the  undersigned  being obligated to perform as agreed herein
      and each of the  Guarantors  hereby waives any and all rights which it may
      have by statute or otherwise  which would require  Laurus to do any of the
      foregoing.  Each of the Guarantors further consents and agrees that Laurus
      shall be under no obligation to marshal any assets in favor of Guarantors,
      or against or in payment of any or all of the Obligations. The undersigned
      hereby  waives all  suretyship  defenses and any rights to  interpose  any
      defense,  counterclaim or offset of any nature and  description  which the
      undersigned  may have or which may exist between and among Laurus,  Debtor
      and/or the undersigned with respect to the undersigned's obligations under
      this  Guaranty,  or  which  Debtor  may  assert  on the  underlying  debt,
      including but not limited to failure of consideration, breach of warranty,
      fraud,  payment  (other  than cash  payment  in full of the  Obligations),
      statute of frauds, bankruptcy, infancy, statute of limitations, accord and
      satisfaction, and usury.

            (b)  Each  of the  undersigned  further  waives  (i)  notice  of the
      acceptance of this Guaranty, of the making of any such loans or extensions
      of  credit,  and of all  notices  and  demands  of any kind to  which  the
      undersigned  may be entitled,  including,  without  limitation,  notice of
      adverse change in Debtor's financial  condition or of any other fact which
      might materially increase the risk of the undersigned and (ii) presentment
      to or demand of payment  from  anyone  whomsoever  liable  upon any of the
      Obligations,  protest, notices of presentment,  non-payment or protest and
      notice of any sale of collateral security or any default of any sort.

            (c)  Notwithstanding any payment or payments made by the undersigned
      hereunder,  or any setoff or  application  of funds of the  undersigned by
      Laurus,  the undersigned  shall not be entitled to be subrogated to any of
      the rights of Laurus against Debtor or against any collateral or guarantee
      or right of offset held by Laurus for the payment of the Obligations,  nor
      shall the  undersigned  seek or be  entitled to seek any  contribution  or
      reimbursement  from Debtor in respect of payments made by the  undersigned
      hereunder,  until all amounts  owing to Laurus by Debtor on account of the
      Obligations  are paid in full and  Laurus'  obligation  to  extend  credit
      pursuant to the Documents have been terminated.  If,  notwithstanding  the
      foregoing,  any amount shall be paid to the undersigned on account of such
      subrogation  rights at any time when all of the Obligations shall not have
      been paid in full and Laurus'  obligation to extend credit pursuant to the
      Documents shall not have been terminated, such amount shall be held by the
      undersigned  in trust  for  Laurus,  segregated  from  other  funds of the
      undersigned,  and shall  forthwith  upon,  and in any event within two (2)
      business days of, receipt by the undersigned,  be turned over to Laurus in
      the  exact  form  received  by  the  undersigned  (duly  endorsed  by  the
      undersigned  to  Laurus,   if  required),   to  be  applied   against  the
      Obligations,  whether  matured or  unmatured,  in such order as Laurus may
      determine, subject to the provisions of the Documents. Any and all present
      and future debts and  obligations of Debtor to any of the  undersigned are
      hereby  waived and  postponed  in favor


                                       3


      of, and  subordinated  to the full payment and performance of, all present
      and future debts and Obligations of Debtor to Laurus.

      4. Security. All sums at any time to the credit of the undersigned and any
property of the  undersigned  in Laurus'  possession or in the possession of any
bank, financial institution or other entity that directly or indirectly, through
one or more  intermediaries,  controls or is  controlled  by, or is under common
control with, Laurus (each such entity, an "Affiliate")  shall be deemed held by
Laurus or such Affiliate, as the case may be, as security for any and all of the
undersigned's  obligations  to Laurus and to any Affiliate of Laurus,  no matter
how or when arising and whether under this or any other instrument, agreement or
otherwise.

      5. Representations and Warranties.  Each of the undersigned  respectively,
hereby   jointly  and   severally   represents   and  warrants   (all  of  which
representations   and  warranties   shall  survive  until  all  Obligations  are
indefeasibly   satisfied  in  full  and  the  Documents  have  been  irrevocably
terminated), that:

      to the extent  that the failure to obtain any of the  foregoing  could not
      reasonably be expected to have, either individually or in the aggregate, a
      Material Adverse Effect.

      default shall occur and be continuing  under any agreement  made by Debtor
      or any of the  undersigned  to  Laurus,  or  either  Debtor  or any of the
      undersigned  should  at any  time  become  insolvent,  or  make a  general
      assignment,  or if a proceeding  in or under any  Insolvency  Law shall be
      filed or commenced by, or in respect of, any of the  undersigned,  or if a
      notice of any lien, levy, or assessment is filed of record with respect to
      any assets of any of the  undersigned  by the United  States of America or

            (b) Each of the  undersigned  will  promptly  notify  Laurus  of any
      default by such undersigned in its respective performance or observance of
      any term or condition of any agreement to which the undersigned is a party

maintained as security for the Obligations.

      8.  Costs.  The  undersigned  shall pay on  demand,  all  costs,  fees and

the undersigned's


                                       5

subsequently invalidated,  declared to be fraudulent or preferential,  set aside
and/or  required to be repaid to a trustee,  receiver,  or any other party under

proceeding,   shall  be  binding  upon  the   undersigned  for  the  purpose  of
establishing  the items therein set forth and shall constitute prima facie proof
thereof.

      12. No Waiver. No failure on the part of Laurus to exercise,  and no delay
in exercising,  any right,  remedy or power  hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise by Laurus of any right, remedy
or power  hereunder  preclude  any other or future  exercise  of any other legal
right, remedy or power. Each and every right, remedy and power hereby granted to
Laurus or  allowed  it by law or other  agreement  shall be  cumulative  and not
exclusive of any other, and may be exercised by Laurus at any time and from time
