     1. Calculation and Payment of Principal and Interest.

     (a) The principal amount of this note ("Note") shall be due and payable on
January 24, 2012 (the "Maturity Date"). No payments of principal are required to
be paid until the Maturity Date.

     (b) The principal amount of this Note outstanding from time to time shall

such principal amount has been repaid in full. Interest shall be payable as
provided below on the last day of each March, June, September and December (each
an "Interest Payment Date") commencing March 31, 2002, and on the Maturity Date.
Interest hereon shall be computed on the basis of a 360-day year. If any payment
to be made by the Company under this Note shall become due on a Saturday or
Sunday or a business holiday under the law of the State of New York, such
payment shall be made on the next succeeding business day, and any extension of
time shall be included in computing any interest in respect of such payment.

     (c) Notwithstanding the preceding paragraph, (i) on any Interest Payment
Date occurring prior to the first anniversary of the date hereof, the Company
may elect to pay up to 100% of the interest then due on this Note by increasing
the principal amount of this Note by the amount of interest as to which the
Company makes such election, (ii) on any Interest Payment Date occurring on or
after the first anniversary of the date hereof and prior to the second
anniversary of the date hereof, the Company may elect to pay up to 50% of the
interest then due on this Note by increasing the principal amount of this Note
by the amount of interest as to which the Company makes such election, and (iii)
on any Interest Payment Date occurring on or after the second anniversary of the
date hereof, Holder may, in its sole discretion, elect, in lieu of receiving all
interest then due on this Note in cash, to require the Company to pay a portion
of such interest (up to 100% thereof), as specified by Holder, by increasing the
principal amount of this Note by the amount of interest as to which Holder makes
such election. In the event an election is made by the Company pursuant to
clause (i) or (ii) of the preceding sentence or by Holder pursuant to clause
(iii) of the preceding sentence, the party making such election shall given
written notice thereof to the other at least 10 days prior to the applicable
Interest Payment Date, specifying the amount or portion of the interest payable
on such Interest Payment Date as to which such election is being made. On the
applicable Interest Payment Date, the Company shall send a written notice to
Holder setting forth the new principal amount of this Note after giving effect
to such election. Any portion of the interest on this Note as to which an
election under this paragraph is not made shall be paid in cash on the
applicable Interest Payment Date.

     (d) If the Company shall default in the payment of any principal of, or any
interest on, this Note when due (whether at maturity, by acceleration or
otherwise), the Company shall thereafter, until the date of actual payment, pay
interest from time to time on

                                       2

demand on such overdue principal and, to the extent legally permitted, overdue
interest at an annual rate of 14 %, provided that such rate shall not exceed the
maximum permitted by applicable law.

     (e) Each payment of principal and interest and any other amounts due
hereunder shall be made by not later than 2:00 p.m. New York time, on the date
such payment is due.

     2.   Subordination.

     Notwithstanding anything to the contrary in this Note, the payment of the
principal of and interest on this Note is subordinated, to the extent and in the
manner provided in the Subordination Agreement dated as of January 25, 2002,
among the Holder, the Company and CapitalSource Finance, LLC ("CapitalSource")
(the "Subordination Agreement"), to the prior payment in full of the Senior
Indebtedness (as such term is defined in the Subordination Agreement).
Notwithstanding the foregoing, at no time shall any amount due hereunder be
subordinated to any Senior Indebtedness in excess of $13,000,000. This Note
shall rank pari passu with the Note dated the date hereof in the principal
amount of $100,000 issued to Linda Yimoyines.

     3.   Prepayments.

     The Company may, at its option, at any time and from time to time, prepay
all or any part of the unpaid principal balance of this Note, without penalty or
premium, provided that concurrently with each such prepayment the Company shall
pay (in cash) accrued interest (and other amounts due hereunder) on the
principal amount so prepaid to the date of prepayment.

claims of any kind which, if unpaid, might become a lien on any of its property;
provided that the foregoing shall not require the Company or any such subsidiary

due, including all interest, fees, costs, expenses and attorneys' fees for which
the Company is now or hereafter becomes liable to pay under any agreement or by
law; provided, however, that Indebtedness shall not include operating leases,

<PAGE>

($250,000) in the aggregate, net of insurance proceeds, and if, within thirty

process shall not have been stayed, paid or discharged;

     (d) (i) Failure of the Company to pay when due any principal of or interest
on the Senior Indebtedness beyond the end of any grace period provided therefor,

dated as of January 25, 2002 between the Company and CapitalSource (the
"CapitalSource Credit Agreement"), or the occurrence of any other event,
condition or circumstance in respect of the CapitalSource Credit Agreement, if

vacated or dismissed within 60 days after such filing or commencement), have any
liquidator, administrator, trustee or custodian appointed with respect to it or
any substantial portion of its business or assets, make a general assignment for
the benefit of creditors or generally admit its inability to pay its debts as

presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived, anything contained in this Note to the contrary
notwithstanding, in which event, Holder shall be entitled to receive the
principal hereof together with the interest accrued hereon, provided, however,
that Holder by written notice to the Company, may waive any Default and/or

unenforceable, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Note, and this Note shall be construed as if any
invalid, illegal or unenforceable provisions had not been contained herein;
provided, however, that default in the performance or observance by the Company
of any provision of this Note which has been held to be invalid, illegal or
unenforceable shall, notwithstanding such invalidity, illegality or
unenforceability, constitute a Default hereunder, if such default would have
constituted a Default without regard to such invalidity, illegality or
unenforceability.

in connection with the enforcement of this Note or Holder's rights hereunder.

     (i) Holder, the Company and any guarantors, endorsers and any other person

agrees that Holder may extend the terms for payment or accept partial payment
and the Holder may compromise, subordinate, or take any other action or make any
change with respect to any security in which it hereafter has any interest, all
without discharging or releasing the Company from any of its obligation
hereunder.

     (j) If this Note is mutilated, lost, stolen or destroyed, the Company shall
issue a new note of like form and maturity to Holder upon presentment and
surrender of the mutilated Note, in the case of mutilation, and upon receipt of
evidence of loss, theft or destruction and of indemnity in all other cases, each
in form satisfactory to the Company.

     (k) No delay on the part of Holder in exercising any option, power or right
hereunder, shall constitute a waiver thereof, nor shall Holder be estopped from
enforcing the same or any other provision at any later time or in any other
instance.

as follows:

         1. Calculation and Payment of Principal and Interest.

         (a) The principal amount of this note ("Note") shall be due and payable
on January 24, 2012 (the "Maturity Date"). No payments of principal are required
to be paid until the Maturity Date.

         (b) The principal amount of this Note outstanding from time to time

until such principal amount has been repaid in full. Interest shall be payable
as provided below on the last day of each March, June, September and December
(each an "Interest Payment Date") commencing March 31, 2002, and on the Maturity
Date. Interest hereon shall be computed on the basis of a 360-day year. If any
payment to be made by the Company under this Note shall become due on a Saturday

payment shall be made on the next succeeding business day, and any extension of
time shall be included in computing any interest in respect of such payment.
Principal and, subject to paragraph 1(c) below, interest on this Note are
payable in lawful money of the United States of America which at the time of
payment is legal tender for the payment of public and private debts.

<PAGE>

         (c) Notwithstanding the preceding paragraph, (i) on any Interest
Payment Date occurring prior to the first anniversary of the date hereof, the
Company may elect to pay up to 100% of the interest then due on this Note by
increasing the principal amount of this Note by the amount of interest as to
which the Company makes such election, (ii) on any Interest Payment Date
occurring on or after the first anniversary of the date hereof and prior to the
second anniversary of the date hereof, the Company may elect to pay up to 50% of
the interest then due on this Note by increasing the principal amount of this

(iii) on any Interest Payment Date occurring on or after the second anniversary
of the date hereof, Holder may, in its sole discretion, elect, in lieu of
receiving all interest then due on this Note in cash, to require the Company to
pay a portion of such interest (up to 100% thereof), as specified by Holder, by
increasing the principal amount of this Note by the amount of interest as to
which Holder makes such election. In the event an election is made by the
Company pursuant to clause (i) or (ii) of the preceding sentence or by Holder
pursuant to clause (iii) of the preceding sentence, the party making such
election shall given written notice thereof to the other at least 10 days prior
to the applicable Interest Payment Date, specifying the amount or portion of the
interest payable on such Interest Payment Date as to which such election is
being made. On the applicable Interest Payment Date, the Company shall send a
written notice to Holder setting forth the new principal amount of this Note
after giving effect to such election. Any portion of the interest on this Note

orders, receipts, correspondence and other data relating to the assets of the
Company or such subsidiary. All such inspections or audits shall be at the
Company's expense.

         (c) Insurance. The Company will maintain, and cause each subsidiary of

setting forth in reasonable detail the nature and extent of all insurance
maintained by the Company and its subsidiaries.

         (d) Compliance with Laws; Payment of Taxes and Liabilities. The Company
will (i) comply, and cause each subsidiary of the Company to comply, in all
material respects with all applicable laws, rules, regulations, decrees, orders,

<PAGE>

claims of any kind which, if unpaid, might become a lien on any of its property;
provided that the foregoing shall not require the Company or any such subsidiary
to pay any such tax or charge so long as it shall contest the validity thereof
in good faith by appropriate proceedings and shall set aside on its books
adequate reserves with respect thereto in accordance with generally accepted
accounting principles.

         (e) Maintenance of Existence, etc. The Company will maintain and
preserve, and cause each Subsidiary to maintain and preserve, (a) its existence
and good standing in the jurisdiction of its organization and (b) its
qualification to do business and good standing in each jurisdiction where the
nature of its business makes such qualification necessary (except in those
instances in which the failure to be qualified or in good standing would not
have a material adverse effect on the Company).

         (f) Limitation on Senior and Secured Indebtedness. Without the prior
written consent of Palisade, the Company will not create, incur or assume (i)
any Indebtedness ranking senior to or pari passu with this Note, or (ii) any
Indebtedness secured by a lien on any asset of the Company or any subsidiary of
the Company, in each case other than (x) the Senior Indebtedness, (y)

Indebtedness approved by the Palisade. As used herein, "Indebtedness" means any
and all loans, advances, indebtedness, obligations, liabilities, covenants and
duties at any time owed by the Company or any subsidiary of the Company, whether
voluntary or involuntary and however arising, direct or indirect, absolute or
contingent, liquidated or unliquidated, determined or undetermined, secured or

due, including all interest, fees, costs, expenses and attorneys' fees for which
the Company is now or hereafter becomes liable to pay under any agreement or by
law; provided, however, that Indebtedness shall not include operating leases,
trade payables or other liabilities of the Company or its subsidiaries incurred
in the ordinary course or business which do not relate to borrowed funds.

the Company will not, and will not permit any subsidiary of the Company to, (A)
make any distribution to the Company's shareholders, (B) purchase or redeem any

in its sole discretion. Notwithstanding the foregoing, (i) any subsidiary of the
Company may pay dividends or make other distributions to the Company or to a
wholly-owned subsidiary of the Company and (ii) the Company may pay dividends or
make other distributions to, or purchase or redeem capital stock or other equity

of Palisade, the Company will not, and will not permit any subsidiary of the
Company to, (i) become a party to any merger or consolidation, or (ii) sell,
transfer, convey or lease all or substantially all its assets, except for any
such merger, consolidation, sale, transfer, conveyance, lease or assignment of
or by any wholly-owned subsidiary into the Company or into, with or to any other
wholly-owned subsidiary, other than (v) the merger of a subsidiary into another

their respective businesses, (y) dispositions of machinery and equipment no

for fair value in cash of assets that the board of directors of the Company
determines in good faith are no longer used or useful in the business of the
Company and its subsidiaries.

consent of Palisade, the Company will not, and will not permit the Certificate
of Incorporation, By-Laws or other organizational documents of the Company to be
amended or modified in any way which might reasonably be expected to adversely
affect the interests of the Holder.

         (j) Inconsistent Agreements. Without the prior written consent of
Palisade, the Company will not, and will not permit any subsidiary of the
Company to, enter into any agreement containing any provision which would (a) be
violated or breached by the performance by the Company of any of its obligations
hereunder, or (b) create or permit to exist or become effective any restriction
on the ability of any subsidiary to (i) pay dividends or make other
distributions to the Company or any other applicable subsidiary, or pay any

Note and such principal or interest shall remain unpaid for five days after the

                                      -9-
<PAGE>

($250,000) in the aggregate, net of insurance proceeds, and if, within thirty
(30) days after the entry, issue or levy thereof, such judgment, warrant or
process shall not have been stayed, paid or discharged;

         (d) (i) Failure of the Company to pay when due any principal of or
interest on the Senior Indebtedness beyond the end of any grace period provided
therefor, or (ii) any breach or default by the Company with respect to any other
terms of the Amended and Restated Revolving Credit, Term Loan and Security
Agreement dated as of January 25, 2002 between the Company and CapitalSource
(the "CapitalSource Credit Agreement"), or the occurrence of any other event,
condition or circumstance in respect of the CapitalSource Credit Agreement, if
in any case under clause (i) or clause (ii) such failure, breach or default or
such event, condition or circumstance has resulted in the Senior Indebtedness
becoming or being declared due and payable (or redeemable) prior to its stated
maturity;

         (e) The Company shall file a petition for relief or commence a
proceeding under any bankruptcy, insolvency, reorganization or similar law, have
any such petition filed or proceeding commenced against it (unless, in the case
of a petition filed or a proceeding commenced against the Company, the same is
vacated or dismissed within 60 days after such filing or commencement), have any
liquidator, administrator, trustee or custodian appointed with respect to it or
any substantial portion of its business or assets, make a general assignment for

then, and in each and every such case, subject to the provisions of paragraph 2
hereof, the Holder shall have the right to declare this Note due and payable
(or, in the case of a Default described in clause (e) of this paragraph 6, this
Note shall automatically become due and payable) without

                                      -10-
<PAGE>

presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived, anything contained in this Note to the contrary
notwithstanding, in which event, Holder shall be entitled to receive the
principal hereof together with the interest accrued hereon, provided, however,
that Holder by written notice to the Company, may waive any Default and/or
rescind and annul any such acceleration; but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent Default, or shall
impair any right consequent thereon.

         7. Assignment.

         Holder may at any time transfer, negotiate or assign this Note, without
the Company's prior consent and, in such case, such transferee shall become
entitled to all of Holder's rights, remedies and privileges hereunder and be
bound by the terms of this Note, including but not limited to the subordination
provisions hereof, and reference herein to Holder shall be deemed to refer to
such transferee.

         8. Miscellaneous.

         (a) All notices, demands, requests and other communications to be given
or delivered pursuant to this Note shall be deemed to have been given when
personally delivered or when received, if mailed by certified or registered

         (b) To the extent the Company makes a payment or payments to Holder,
which payment(s) are subsequently invalidated, declared to be fraudulent or
preferential, set

                                      -11-
<PAGE>

aside, and/or required to be repaid to a trustee, receiver, or any other person
under any bankruptcy, insolvency or similar laws or equitable cause, then, to
the extent such payment(s) are recovered from or repaid by Holder, the
obligations or part thereof intended to be satisfied shall be revived and
continue in full force and effect, as if such payment(s) had not been received
by Holder.

         (c) The words "herein," "hereof," "hereunder" and other words of
similar import refer to this Note as a whole and not to any particular
provision.

         (d) The rights, remedies and benefits of Holder hereunder are
cumulative and not exclusive or in limitation of any other rights, remedies or
benefits Holder may have under any agreement, at law, in equity or otherwise.

         (e) The Company agrees to do such further acts and things, and to
execute and deliver such additional agreements, documents and instruments as
Holder may from time to time reasonably request in order to better assure and
confirm unto Holder its rights and remedies hereunder.

         (f) If any provision of this Note shall be held to be invalid, illegal
or unenforceable, such invalidity, illegality or unenforceability shall not
affect any other provisions of this Note, and this Note shall be construed as if
any invalid, illegal or unenforceable provisions had not been contained herein;
provided, however, that default in the performance or observance by the Company
of any provision of this Note which has been held to be invalid, illegal or
unenforceable shall, notwithstanding such invalidity, illegality or
unenforceability, constitute a Default hereunder, if such default would have
constituted a Default without regard to such invalidity, illegality or
unenforceability.

         (g) The headings contained in this Note are for convenience only and
shall not control or affect the meaning or construction of any provisions
hereof.

         (h) If any Default shall occur and Holder proceeds to enforce or pursue
any legal or equitable remedies, the Company agrees to pay all costs, expenses
and fees incurred by Holder (including reasonable attorneys' fees and
disbursements) in connection with the enforcement of this Note or Holder's
rights hereunder.

         (i) Holder, the Company and any guarantors, endorsers and any other
person at any time liable for the payment hereof, severally waive the right to a

any time liable for the payment hereof, severally waive demand, protest and
notice of protest, diligence, and all other demands and notices in connection
with the delivery, acceptance, performance and enforcement of this Note, and the
Company agrees that Holder may extend the terms for payment or accept partial
payment and the Holder may compromise, subordinate, or take any other action or
make any change with respect to any security in which it hereafter has any
interest, all without discharging or releasing the Company from any of its
obligation hereunder.

         (j) If this Note is mutilated, lost, stolen or destroyed, the Company
shall issue a new note of like form and maturity to Holder upon presentment and
surrender of the mutilated Note, in the case of mutilation, and upon receipt of
evidence of loss, theft or destruction and of indemnity in all other cases, each
in form satisfactory to the Company.

         (k) No delay on the part of Holder in exercising any option, power or
right hereunder, shall constitute a waiver thereof, nor shall Holder be estopped
from enforcing the same or any other provision at any later time or in any other
instance.

                                      -13-
