successors,  endorsees  and  assigns  the prompt  payment  when due  (whether by
acceleration or otherwise) of all present and future obligations and liabilities
of any and all kinds of each  Company  to Laurus and of all  instruments  of any

each Related  Agreement  referred to in the Securities  Purchase  Agreement (the

amended,  modified,   restated  and/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  obligations  or liabilities of such Company 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 any  Company  under Title 11,
United States Code, including,  without limitation,  obligations or indebtedness
of any Company 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 any Company or
with  any  other  party  to or  person  liable  on any of  the  Obligations,  or
interested

                                       12



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 any Company 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 Guaranty
shall  be  effective  regardless  of the  subsequent  incorporation,  merger  or
consolidation  of  any  Company,  or any  change  in  the  composition,  nature,
personnel or location of any Company and shall extend to any successor entity to
each Company,  including a debtor in possession or the like under any Insolvency
Law.

        2.      GUARANTY ABSOLUTE.  Subject to Section 5(c) hereof,  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 any  Company  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 a Company will contract additional  obligations and liabilities
for which  Guarantors may be liable  hereunder  after such  Company's  financial
condition   or  ability  to  pay  its  lawful  debts  when  they  fall  due  has
deteriorated, whether or not such Company has properly authorized incurring such
additional obligations and liabilities.  The undersigned acknowledge that (i) no
oral representations,  including any representations to extend credit or provide
other  financial  accommodations  to any  Company,  have  been made by Laurus to
induce the  undersigned  to enter into this  Guaranty and (ii) any  extension of
credit  to any  Company  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 any
Company,  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

                                       2



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 any Company
        or  any  other  person  or  entity  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.  Each of 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,  any
        Company  and/or  the  undersigned  with  respect  to  the  undersigned's
        obligations under this Guaranty,  or which any Company 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  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 any
        Company'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 any Company 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 any Company in
        respect of payments made by the undersigned hereunder, until all amounts
        owing to  Laurus by each  Company  on  account  of the  Obligations  are
        indefeasibly  paid in full  and  Laurus'  obligation  to  extend  credit
        pursuant  to  the  Documents  has  been  irrevocably   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)

                                       3



        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 obligations and liabilities of each Company to any of
        the  undersigned  are  hereby  waived  and  postponed  in favor of,  and
        subordinated  to the full payment and performance of, all Obligations of
        each Company 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  and  liabilities  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 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:

                (a)     CORPORATE  STATUS.  It is a corporation,  partnership or
        limited  liability  company,  as the case may be, duly  formed,  validly
        existing  and in good  standing  under the laws of its  jurisdiction  of
        formation  indicated  on the  signature  page hereof and has full power,
        authority and legal right to own its property and assets and to transact
        the business in which it is engaged.

        and legal right to execute and deliver,  and to perform its  obligations
        under, this Guaranty and has taken all necessary corporate,  partnership

        the execution, delivery and performance of this Guaranty.

                (c)     LEGAL,  VALID  AND  BINDING  CHARACTER.   This  Guaranty
        constitutes  its legal,  valid and  binding  obligation  enforceable  in
        accordance with its terms,  except as  enforceability  may be limited by
        applicable bankruptcy, insolvency,  reorganization,  moratorium or other
        laws of general  application  affecting  the  enforcement  of creditor's
        rights and general  principles of equity that restrict the  availability
        of equitable or legal remedies.

                (d)     VIOLATIONS.  The execution,  delivery and performance of
        this Guaranty will not violate any  requirement  of law applicable to it
        or any  contract,  agreement or  instrument to which it is a party or by
        which it or any of its  property  is bound or result in the  creation or
        imposition  of any  mortgage,  lien or other  encumbrance  other than in
        favor  of  Laurus  on any of its  property  or  assets  pursuant  to the
        provisions  of any  of the  foregoing,  which,  in any of the  foregoing
        cases,  could reasonably be expected to have, either  individually or in
        the aggregate, a Material Adverse Effect.

                                       4



                (e)     CONSENTS OR APPROVALS. No consent of any other person or
        entity (including,  without limitation, any creditor of the undersigned)

        by, notice or report to, or  registration,  filing or declaration  with,
        any governmental authority is required in connection with the execution,
        delivery,  performance,  validity or  enforceability of this Guaranty by
        it, except 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.

                (f)     LITIGATION. No litigation, arbitration, investigation or
        administrative   proceeding  of  or  before  any  court,  arbitrator  or
        governmental authority, bureau or agency is currently pending or, to the
        best of its  knowledge,  threatened (i) with respect to this Guaranty or
        any of the transactions contemplated by this Guaranty or (ii) against or
        affecting  it, or any of its property or assets,  which,  in each of the
        foregoing cases, if adversely  determined,  could reasonably be expected
        to have a Material Adverse Effect.

                (g)     FINANCIAL BENEFIT. It has derived or expects to derive a
        financial  or other  advantage  from each and  every  loan,  advance  or
        extension  of  credit  made  under  the  Documents  or other  Obligation
        incurred by the Companies to Laurus.

                (h)     SOLVENCY. As of the date of this Guaranty,  (a) the fair
        saleable  value of its  assets  exceeds  its  liabilities  and (b) it is
        meeting its current liabilities as they mature.

        6.      ACCELERATION.

                (a)     If any  breach of any  covenant  or  condition  or other
        event of default shall occur and be continuing  under any agreement made
        by any  Company  or any of the  undersigned  to  Laurus,  or either  any
        Company 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  any   department,   agency,   or
        instrumentality  thereof,  or if any taxes or debts owing at any time or
        times  hereafter to any one of them becomes a lien or  encumbrance  upon
        any assets of the undersigned in Laurus' possession,  or otherwise,  any
        and all Obligations  shall for purposes  hereof,  at Laurus' option,  be
        deemed due and  payable  without  notice  notwithstanding  that any such
        Obligation is not then due and payable by the Companies.

                (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 if the effect of such  default  is to cause,  or
        permit the holder of any obligation under such agreement to cause,  such
        obligation  to become due prior to its stated  maturity  and, if such an
        event  occurs,   Laurus  shall  have  the  right  to   accelerate   such
        undersigned's obligations hereunder.

        7.      PAYMENTS  FROM  GUARANTORS.  Laurus,  in its sole  and  absolute
discretion,  with or without notice to the undersigned,  may apply on account of
the  Obligations any payment from the  undersigned or any other  guarantors,  or
amounts realized from any security for the

                                       5



Obligations,  or may deposit any and all such amounts realized in a non-interest
bearing cash  collateral  deposit  account to be  maintained as security for the
Obligations.

        8.      COSTS. The undersigned shall pay on demand,  all costs, fees and
expenses  (including  expenses  for legal  services of every  kind)  relating or
incidental to the enforcement or protection of the rights of Laurus hereunder or
under any of the Obligations.

        9.      NO TERMINATION.  This is a continuing  irrevocable  guaranty and
shall remain in full force and effect and be binding upon the  undersigned,  and
each of the undersigned's  successors and assigns,  until all of the Obligations
have been  indefeasibly  paid in full and Laurus'  obligation  to extend  credit
pursuant to the Documents has been irrevocably terminated. If any of the present
or future Obligations are guarantied by persons,  partnerships,  corporations or
other entities in addition to the undersigned,  the death,  release or discharge
in whole or in part or the  bankruptcy,  merger,  consolidation,  incorporation,
liquidation  or dissolution of one or more of them shall not discharge or affect
the liabilities of any undersigned under this Guaranty.

        10.     RECAPTURE.   Anything   in  this   Guaranty   to  the   contrary
notwithstanding,  if Laurus  receives  any payment or payments on account of the
liabilities guaranteed hereby, which payment or payments or any part thereof are
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
any Insolvency Law, common law or equitable doctrine,  then to the extent of any
sum not finally  retained by Laurus,  the  undersigned's  obligations  to Laurus
shall be reinstated  and this Guaranty shall remain in full force and effect (or
be reinstated) until payment shall have been made to Laurus, which payment shall
be due on demand.

        11.     BOOKS AND RECORDS.  The books and records of Laurus  showing the
account  between  Laurus and each Company shall be admissible in evidence in any
action or 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 to time.

        13.     WAIVER OF JURY TRIAL.  EACH OF THE UNDERSIGNED  DESIRES THAT ITS
DISPUTES BE RESOLVED BY A JUDGE APPLYING APPLICABLE LAWS. THEREFORE,  TO ACHIEVE
THE BEST  COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION,
EACH OF THE UNDERSIGNED HERETO WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION,

this Guaranty is made voluntarily and  unconditionally  after  consultation with
outside  legal  counsel  and  with  full  knowledge  of  its   significance  and
consequences,  with the understanding  that events giving rise to any defense or
right waived may diminish,  destroy or otherwise  adversely  affect rights which
such  Guarantor  otherwise  may have  against any  Company,  Laurus or any other
person or entity or against any collateral.  If,  notwithstanding  the intent of
the  parties  that  the  terms of this  Guaranty  shall  control  in any and all
circumstances,  any such waivers or consents are determined to be  unenforceable
under  applicable  law,  such  waivers and  consents  shall be  effective to the
maximum extent permitted by law.

        16.     SEVERABILITY.  To the extent  permitted by  applicable  law, any
provision  of  this  Guaranty  which  is  prohibited  or  unenforceable  in  any
jurisdiction shall, as to such jurisdiction,

                                       7



be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

        17.     AMENDMENTS,  WAIVERS. No amendment or waiver of any provision of
this Guaranty nor consent to any departure by the undersigned therefrom shall in
any event be effective  unless the same shall be in writing  executed by each of
the undersigned  directly  affected by such amendment  and/or waiver and Laurus.

        18.     NOTICE.  All  notices,  requests  and  demands  to or  upon  the
undersigned,  shall be in writing and shall be deemed to have been duly given or
made (a) when  delivered,  if by hand,  (b) three  (3) days  after  being  sent,
postage  prepaid,  if by  registered  or  certified  mail,  (c)  when  confirmed
electronically,  if by  facsimile,  or (d) when  delivered,  if by a  recognized
overnight  delivery  service in each event,  to the numbers  and/or  address set
forth beneath the signature of the undersigned.

        19.     SUCCESSORS. Laurus may, from time to time, without notice to the
undersigned,  sell, assign,  transfer or otherwise dispose of all or any part of
the  Obligations  and/or  rights  under  this  Guaranty.  Without  limiting  the
generality of the foregoing,  Laurus may assign, or grant participations to, one
or more banks,  financial  institutions or other entities all or any part of any
of the  Obligations.  In each such event,  Laurus,  its  Affiliates and each and
every immediate and successive purchaser,  assignee, transferee or holder of all
or any part of the Obligations shall have the right to enforce this Guaranty, by
legal action or  otherwise,  for its own benefit as fully as if such  purchaser,
assignee,  transferee  or holder  were  herein by name  specifically  given such
right.  Laurus shall have an  unimpaired  right to enforce this Guaranty for its
benefit  with respect to that  portion of the  Obligations  which Laurus has not
disposed of, sold, assigned, or otherwise transferred.

        20.     JOINDER.  It is understood  and agreed that any person or entity
that  desires  to become a  Guarantor  hereunder,  or is  required  to execute a
counterpart of this Guaranty after the date hereof pursuant to the  requirements
of any Document,  shall become a Guarantor  hereunder by (x) executing a joinder
agreement  in  form  and  substance   satisfactory  to  Laurus,  (y)  delivering
supplements  to such  exhibits  and annexes to such  Documents  as Laurus  shall
reasonably  request and/or as may be required by such joinder  agreement and (z)
taking all  actions as  specified  in this  Guaranty as would have been taken by
such such Guarantor had it been an original party to this Guaranty, in each case
with  all  documents  required  above to be  delivered  to  Laurus  and with all
documents and actions required above to be taken to the reasonable  satisfaction
of Laurus.

        21.     RELEASE.  Nothing  except  indefeasible  payment  in full of the
Obligations  shall  release any of the  undersigned  from  liability  under this
Guaranty.

        22.     REMEDIES NOT  EXCLUSIVE.  The remedies  conferred upon Laurus in
this  Guaranty are intended to be in addition to, and not in  limitation  of any
other remedy or remedies available to Laurus under applicable law or otherwise.

        23.     LIMITATION OF OBLIGATIONS  UNDER THIS  GUARANTY.  Each Guarantor
and Laurus (by its acceptance of the benefits of this Guaranty)  hereby confirms
that it is its intention that this

                                       8



Guaranty not constitute a fraudulent  transfer or conveyance for purposes of the
Bankruptcy Code, the Uniform Fraudulent Conveyance Act of any similar Federal or
state law. To effectuate the foregoing intention,  each Guarantor and Laurus (by
its acceptance of the benefits of this Guaranty) hereby  irrevocably agrees that
the Obligations  guaranteed by such Guarantor shall be limited to such amount as
will,  after giving effect to such maximum  amount and all other  (contingent or
otherwise)  liabilities  of such Guarantor that are relevant under such laws and
after  giving  effect to any rights to  contribution  pursuant to any  agreement
providing  for an  equitable  contribution  among such  Guarantor  and the other
Guarantors  (including  this  Guaranty),  result  in  the  Obligations  of  such
Guarantor under this Guaranty in respect of such maximum amount not constituting
a fraudulent transfer or conveyance.
