            SECTION 1.  Agreement  to  Subordinate.  Subordinated  Creditor  and
Debtor  agree that the payment of the  principal  of, and  interest  on, and all
other amounts owing in respect of the  Subordinated  Debt is and shall be hereby
expressly  subordinated,  to the extent and in the manner hereinafter set forth,
to the prior payment in full of all indebtedness, liabilities and obligations of

Notes or any other document or instrument evidencing,  securing, guaranteeing or
in any way pertaining to the Loans (collectively the "Loan Documents"),  and all
other indebtedness owing by Borrower and/or Parent to Lender howsoever evidenced
(such documents evidencing,  securing, guaranteeing, or pertaining to such other
indebtedness  are also included within the definition of the "Loan  Documents"),
whether now or hereafter  existing,  whether for principal,  interest (including
without  limitation  interest  accruing after the commencement of any proceeding
referred to in Section 3), or whether  fees,  expenses  or  otherwise  (all such
obligations being the "Senior Indebtedness").

            SECTION 2. A. No Payment on the Subordinated Debt.

            (i) Unless and until all Senior  Indebtedness  has been paid in full
and no commitment is in existence to advance or create Senior Indebtedness:

                       (A) except as provided  in 2.B and 2.C, no payment  shall
            be made  by  Debtor,  directly  or  indirectly,  in  respect  of the
            principal  of, or  interest  or premium  on, or  otherwise  owing in
            respect of, the Subordinated Debt, and

                       (B)  except  as  provided  in 2.B and  2.C,  Subordinated
            Creditor shall not ask, demand, sue for, take any action to enforce,
            take or receive,  directly or indirectly,  in cash or other property
            (other than Common Stock),  by sale,  set-off or in any other manner
            whatsoever  any  moneys  which may now or  hereafter  be owing  with
            respect to the Subordinated Debt.

Notwithstanding the foregoing,  Subordinated  Creditor may demand, sue for, take
any  action,  or  commence  proceedings  to  enforce  the  following  so long as
Subordinated Creditor does not breach its agreements in Section 4, below:

            (X)  Debtor's   obligations   and   agreements  in  respect  of  the
            Subordinated  Debt  or  under  the  Subordinated  Note  and  related
            documents that are non-monetary in nature, and

            (Y)   Subordinated   Creditor's   rights  and  remedies   under  the
            Subordinated  Note and  related  documents  (other  than  rights and
            remedies   consisting  of  the  payment  of  cash  to   Subordinated
            Creditor).

            (ii)  In the  event  that,  notwithstanding  the  provisions  of the
preceding  subsection (i) of this Section 2.A, and except as provided in 2.B and
2.C below,  Debtor  shall make any  payment on account of the  principal  of, or
interest on, or amounts  otherwise  owing in respect of, the  Subordinated  Debt
while Senior  Indebtedness has not been paid in full or while a commitment is in
existence to advance or create any Senior  Indebtedness,  such payment  shall be
segregated  from other funds and property of  Subordinated  Creditor and held by
the Subordinated  Creditor,  in trust for the benefit of, and shall forthwith be
paid over and delivered to,  Lender or the holder of Senior  Indebtedness  (with
any necessary endorsement) for application pro rata to the payment of all Senior
Indebtedness  remaining  unpaid  to  the  extent  necessary  to pay  all  Senior
Indebtedness  or held as  collateral  in the case of non cash  property  for the
payment of the Senior Indebtedness.

            B.  Principal  and Interest on  Subordinated  Debt Prior to Default.
Notwithstanding anything to the contrary contained in 2.A so long as there shall
exist no Event of Default as  defined in any of the Loan  Documents,  Debtor may
from time to time pay or cause to be paid, and Subordinated Creditor may receive
and retain for its own account, regularly scheduled payments of accrued interest
as and  when  such  payments  are  due  on the  Subordinated  Note.  Debtor  and
Subordinated  Creditor  will not change the






schedule of payments as to principal or interest  without Lender's prior written
consent.  Each of Debtor and  Subordinated  Creditor shall maintain records with
respect to such payments and upon the happening of any Event of Default,  Debtor
shall have no right to make, and  Subordinated  Creditor shall cease to have the
right to receive and retain,  such  payments in cash;  and any  payments in cash
received  by  Subordinated  Creditor  shall be held in trust for the  benefit of
Senior Creditor in accordance with this Agreement.

            C.  Payments  on  Subordinated  Debt in Common  Stock or Addition to
Principal  Amount Due under the  Subordinated  Note.  Whether or not there shall
exist any Event of Default as defined in any of the Loan  Documents,  Debtor may
make,  and  Subordinated  Creditor  may receive and retain for its own  account,
payments  of  principal,  accrued  interest,   penalties,   liquidated  damages,
premiums,   or  any  other  amounts  owing  under  the  Subordinated   Note  and
Registration  Rights Agreement entered into as of the date hereof between Debtor
and the  purchasers  signatory  thereto,  either in the form of Common Stock (as
such term is  defined in the  Subordinated  Note) or by adding the amount of any
such payments to the principal amount due under the  Subordinated  Note (but not
in cash),  pursuant to Section 2(c) of the Registration Rights Agreement entered
into as of the date hereof between Debtor and the purchasers  signatory  thereto
and Section 7 of the Subordinated Note.


         SECTION 3. In Furtherance of Subordination.

            (a) Upon any  distribution  of all or any of the  assets  of  Debtor
(other than assets  constituting  Common Stock)  (whether in connection with the
dissolution, winding up, liquidation, arrangement,  reorganization,  adjustment,
protection,  relief or  composition  of Debtor  or its debts or  whether  in any
bankruptcy, insolvency, rearrangement,  reorganization,  receivership, relief or
similar  proceedings  or whether upon an assignment for the benefit of creditors
or otherwise) the following provisions shall apply:

            (i) Lender or the holder of all Senior  Indebtedness  shall first be
entitled to receive payment in full of the principal thereof,  premium,  if any,
and interest (including  post-petition interest) due thereon before Subordinated
Creditor  or the holder of the  Subordinated  Debt is  entitled  to receive  any
payment on account of the  principal of or interest on or any other amount owing
in respect of the Subordinated Debt;

            (ii) any payment,  dividend or  distribution  of assets of Debtor of
any  kind or  character,  whether  in  cash,  property  or  securities  to which
Subordinated  Creditor or the holder of the Subordinated  Debt would be entitled
except for the provisions of this  Agreement,  shall be paid by the  liquidating
trustee or agent or other person making such payment or distribution,  whether a
trustee in  bankruptcy,  a receiver or  liquidating  trustee or other trustee or
agent,  directly to Lender or the holder of Senior  Indebtedness,  to the extent
necessary to make payment in full of all Senior Indebtedness remaining unpaid;

            (iii) in any such  proceeding,  Lender or the  holder of the  Senior
Indebtedness  is hereby  irrevocably  authorized  and  empowered (in the name of
Subordinated  Creditor or otherwise),  but shall have no obligation,  to demand,
sue for,  collect  and  receive  every  payment or  distribution  referred to in
clauses (i) and (ii) of subsection (a) above and given acquittance  therefor and
to file  claims  and  proofs  of claim and take such  other  action  (including,
without  limitation,  voting the  Subordinated  Debt or  enforcing  any security
interest or other lien securing payment of the Subordinated Debt) as it may deem
necessary or advisable for the exercise or  enforcement  of any of the rights or
interests of Lender or the





holder of Senior Indebtedness hereunder;

            (iv)  in  any  proceeding,  Subordinated  Creditor  shall  duly  and
promptly  take such action to the  extent,  and only to the extent as Lender may
expressly request:

                  (A) to collect the Subordinated Debt for the account of Lender
or the holder of Senior Indebtedness and to file appropriate claims or proofs of
claim in respect of the Subordinated Debt;

                  (B) to execute and deliver to Lender such powers of  attorney,
assignments,  or other  instruments  as it may  request in order to enable it to
enforce any and all claims with respect to, and any security interests and other
liens securing payment of, the Subordinated Debt; and

                  (C)  to  collect  and   receive   any  and  all   payments  or
distributions  which may be payable or  deliverable  upon or with respect to the
Subordinated Debt; and

            (v) in any such proceeding, Subordinated Creditor shall not have any
right  to  setoff  against  the  Subordinated  Debt  any  indebtedness  owed  by
Subordinated  Creditor to Debtor (including,  without  limitation,  any right of
setoff under Section 553 of the  Bankruptcy  Code),  and  Subordinated  Creditor
hereby irrevocably  agrees, to the fullest extent permitted by law, that it will
not exercise (and herein waives) any right of setoff.

If the foregoing  waivers are adjudicated  unenforceable by a court of competent
jurisdiction,  then  Subordinated  Creditor  agrees  that,  in the event that it
exercises any right of setoff in any such proceeding, Subordinated Creditor will
pay directly to Lender or the holder of the Senior Indebtedness remaining unpaid
or unprovided for, an amount equal to the amount of Subordinated  Debt which was
so setoff,  for  application to such Senior  Indebtedness  until all such Senior
Indebtedness shall have been paid in full;

            (b) in the event that,  notwithstanding the foregoing  provisions of
this Section 3, any payment or  distribution  of assets of Debtor of any kind or
character,  whether  in cash,  property  or  securities,  shall be  received  by
Subordinated  Creditor on account of principal or interest on Subordinated  Debt
before all Senior  Indebtedness  is paid in full, or effective  provision  shall
have been made for its payment,  such payment or distribution  shall be received
and held in trust for and  shall be paid  over to  Lender  or the  holder of the
Senior  Indebtedness  remaining unpaid or unprovided for, for application to the
payment of such Senior  Indebtedness  until all such Senior  Indebtedness  shall
have been paid in full; and

            (c)  Lender  or the  holder  of the  Senior  Indebtedness  is hereby
authorized to demand  specific  performance  of this  Agreement,  whether or not
Debtor shall have complied with any of the provisions  hereof  applicable to it,
at any time when  Subordinated  Creditor shall have failed to comply with any of
the provisions of this Agreement applicable to it. Subordinated  Creditor hereby
irrevocably  waives any defense based on the adequacy of a remedy at law,  which
might be asserted as a bar to such remedy of specific performance.

            SECTION 4. Subordination of all Liens  Subordinated  Creditor agrees
that it will  not hold any lien or  security  interest  in any real or  personal
property as security for the Subordinated Debt unless Lender has given its prior
written  consent to the creation  thereof.  In the event  Subordinated  Creditor
shall  acquire any lien or security  interest as security  for the  Subordinated
Debt,  regardless  of whether  such lien or security  interest is  permitted  or
prohibited by this Agreement or the Loan Documents,  Subordinated  Creditor will
hold such lien or security  interest for the benefit of Lender and shall enforce
such lien or security  interest in






accordance with the written  instructions of Lender.  Any cash or other property
received on account of any lien or security  interest  securing the Subordinated
Debt shall be delivered  to Lender and, in the case of cash,  applied to, or, in
the case of other property, held as collateral for, the Senior Indebtedness.  To
the extent that any Subordinated  Debt is now or hereafter  secured by a lien or
security  interest (a "Subordinate  Lien") against any real or personal property
that  is also  subject  to a lien  or  security  interest  securing  the  Senior
Indebtedness  (a  "Senior  Lien"),   Subordinated   Creditor  agrees  that  such
Subordinate Lien shall be second, junior and subordinate to such Senior Lien and
such  Senior  Lien  shall be first and  prior to such  Subordinate  Lien.  It is
further  agreed that the  priorities  specified  in the  preceding  sentence are
applicable  irrespective  of the time or order of  attachment  or  perfection of
liens  and  security  interests,  or the time or order of  filing  of liens  and
security interests,  or the time or order of filing of financing statements,  or
the giving or failure to give notice of the acquisition or expected  acquisition
of purchase money or other security interests.

            SECTION 5. No Commencement of Any Proceeding.  Subordinated Creditor
agrees that, so long as any of the Senior  Indebtedness  shall remain unpaid, it
will not commence,  or join with any creditor other than Lender or the holder of
Senior Indebtedness in commencing, any proceeding for any distribution of all or
any of the  assets of Debtor  (other  than  assets  constituting  Common  Stock)
(whether  in  connection  with  the   dissolution,   winding  up,   liquidation,
arrangement,  reorganization,  adjustment,  protection, relief or composition of
Debtor or its debts or whether  in any  bankruptcy,  insolvency,  rearrangement,
reorganization,  receivership,  relief or similar proceedings or whether upon an
assignment for the benefit of creditors or otherwise).

            SECTION 6. Rights of Subrogation.  Subordinated Creditor agrees that
no  payment  or  distribution  to  Lender or the  holder of Senior  Indebtedness
pursuant to the provisions of this Agreement shall entitle Subordinated Creditor
to  exercise  any  rights of  subrogation  in respect  thereof  until the Senior
Indebtedness shall have been paid in full.

            SECTION 7. Subordination  Legend;  Further Assurances.  Subordinated
Creditor and Debtor will cause each instrument  evidencing  Subordinated Debt to
be endorsed with the following legend:

            "The  indebtedness  evidenced by this  instrument is subordinated to
            the prior payment in full of the Senior  Indebtedness (as defined in
            the Subordination  Agreement  hereinafter  referred to) pursuant to,
            and to the extent provided in, the Subordination Agreement effective
            as of September 8, 2000,  by the maker hereof and payee named herein
            in favor of Lender or the holder of Senior Indebtedness  referred to
            in such Subordination Agreement."

Subordinated  Creditor and Debtor each will further mark its books of account in
such a manner as shall be effective to give proper  notice of the effect of this
Agreement and will, in the case of any Subordinated  Debt which is not evidenced
by any instrument,  upon Lender's  reasonable  request,  cause such Subordinated
Debt to be evidenced by an appropriate  instrument or instruments  endorsed with
the above legend. Subordinated Creditor and Debtor each will, at its expense and
at any time and from time to time,  promptly  execute  and  deliver  all further
instruments and documents,  and take all further actions,  that may be necessary
or desirable,  or that Lender may  reasonably  request,  in order to protect any
right or interest  granted or purported to be granted hereby or to enable Lender
to exercise and enforce its rights and remedies hereunder.

            SECTION  8.  No  Change  in or  Disposition  of  Subordinated  Debt.
Subordinated  Creditor  shall not: (a) cancel or otherwise  discharge any of the
Subordinated Debt, except by the issuance of Common Stock as







permitted  under  the  Subordinated   Debenture,   or  subordinate  any  of  the
Subordinated   Debt  to  any  indebtedness  of  Debtor  other  than  the  Senior
Indebtedness,  except as provided  otherwise in Section 2, above;  or (b) permit
the terms of any of the  Subordinated  Debt to be changed in such a manner as to
have an adverse  effect upon the rights or  interests  of the Lender  under this
Agreement or the Loan Documents.

            SECTION 9.  Agreement by the Debtor.  Debtor agrees that it will not
make any payment of any of the Subordinated  Debt, nor take any other action, in
contravention  of the provisions of this  Agreement.  Nothing  contained in this
Agreement is intended to or shall impair,  as between  Debtor,  on the one hand,
and its  creditors  other than the  holders of the Senior  Indebtedness  and the
Subordinated  Debt,  on the other  hand,  the  obligations  of Debtor to pay the
holders of the Subordinated  Debt all amounts owing on the Subordinated  Debt as
and when the same shall become due and payable in accordance  with its terms, or
to affect the relative  rights of the holders of  Subordinated  Debt, on the one
hand, and creditors of the Debtor other than holders of the Senior Indebtedness,
on the other hand.

            SECTION 10. Senior Indebtedness  Hereunder Not Affected.  All rights
and interests of Lender or the holder of Senior Indebtedness hereunder,  and all
agreements  and  obligations  of  Subordinated  Creditor  and Debtor  under this
Agreement, shall remain in full force and effect irrespective of:

            (i) any lack of validity or  enforceability of all or any portion of
this Agreement;

            (ii) any change in the amount of interest  rate  accruing  on, time,
manner or place of payment of, or in any other term of, all or any of the Senior
Indebtedness,  or any other amendment or waiver of any consent to departure from
any of the Loan Documents,  including, without limitation,  changes in the terms
of  disbursement  of the Loan  proceeds  or  repayment  thereof,  modifications,
extensions  or  renewals  of  payment  dates,  changes in  interest  rate or the
advancement of additional funds by the Lender in its discretion;

            (iii) any exchange,  release or  non-perfection of any collateral or
any release or amendment or waiver of or consent to departure from any guaranty,
for all or any of the Senior Indebtedness; or

            (iv) any other circumstance in respect of this Agreement which might
otherwise  constitute a defense  available  to, or a discharge of, Debtor or any
guarantor  of or in  respect  of the  Senior  Indebtedness  or the  Subordinated
Creditor.

            SECTION  11.  Reinstatement.  This  Agreement  shall  continue to be
effective  or be  reinstated,  as the case may be, if at any time any payment of
any of the Senior  Indebtedness  is rescinded  or must  otherwise be returned by
Lender upon the insolvency, bankruptcy or reorganization of Debtor or otherwise,
all as though such payment had not been made.

            SECTION 12. Waivers. Subordinated Creditor hereby waives promptness,
diligence,  notice of acceptance,  notice of intention to accelerate,  notice of
acceleration and any other notice with respect to any of the Senior Indebtedness
and this Agreement and any requirement that Lender protect,  secure,  perfect or
insure any security  interest or lien or any property subject thereto or exhaust
any right or take any action against Debtor or any other person or entity or any
collateral.  Subordinated  Creditor waives any right or benefit of any notice of
any action, event or circumstance relating to the Senior Indebtedness, including
but not limited to the incurrence,  modification, default, exercise of remedies,
compromise or release of or with respect to Senior Indebtedness.






            SECTION 13. Representations and Warranties.

            (a) Debtor  hereby  represents  and  warrants  as  follows:  (i) the
