         5. Remedies. Upon occurrence of any Default specified in subparagraph
4(j) or (k) above, the entire principal amount due under this Note and all
interest then accrued thereon, and any other liabilities of Maker hereunder,
shall become immediately due and payable all without notice and without
presentment, demand, protest, notice of protest or dishonor, notice of
acceleration or any other notice of default of any kind, all of which are hereby
expressly waived by Maker. Upon the occurrence of any other Default hereunder,
Maker shall have ten business days from the date of such Default to cure such
Default. If such Default is not timely cured, the Holder hereof shall have the
right to declare the entire outstanding principal balance hereof and all accrued
but unpaid interest on this Note at once due and payable (and upon such
declaration, the same shall be at once due and payable) without presentment or
demand for payment and to exercise any of its other right, power and remedies
under this Note or at law or in equity.

         6. Default Rate. It is understood and agreed that time is of the
essence respecting this Note. It is understood and agreed that any past due
principal and/or interest shall bear interest from the date it is due until
paid, at the Maximum Rate.

         7. Representations, Warranties and Covenants of the Maker. The Maker
represents, warrants and covenants to the Payee that the Maker:

                  (a) is a corporation duly organized, validly existing, and in
         good standing under the laws of the State of Delaware;

                  (b) has all requisite corporate power and authority to own,
         lease, license and use its properties and assets and to conduct the
         business in which it is engaged; and

                  (c) is duly licensed or qualified and is in good standing as a
         foreign corporation in each jurisdiction wherein the nature of the
         business transacted by it or the nature of the property owned or leased
         by it makes such licensing or qualification necessary, the failure of
         which would have a material adverse effect on the business, operations,
         properties or condition (financial or otherwise) of the Maker.

         8. Waivers. Except as provided for herein, the Maker and each surety,
guarantor, endorser, or any party ever liable for payment of any sum of money
payable on this Note does hereby severally waive demand, grace, presentment for
payment, notice of dishonor, notice of intent to accelerate, notice of
acceleration, protest, and diligence in


PROMISSORY NOTE - PAGE 3

   4


collecting sums due hereunder and in bringing suit against any party hereto. The
Maker and each surety, guarantor, endorser, or any other party ever liable for
payment of any sum of money payable on this Note further agrees (i) to all
extensions and partial payments, with or without notice, before or after
maturity, (ii) to any substitution, exchange or release of any security now or
hereafter given for this Note, (iii) to the release of any party primarily or
secondarily liable hereon, and (iv) that it will not be necessary for the holder
hereof, in order to enforce payment of this Note, to first institute or exhaust
such holder's remedy against the Maker or any other party liable therefor or
against any security for this Note. No delay or omission on the part of the
Payee in exercising any power or right under this Note shall operate as a waiver
of such power or right, nor shall any single or partial exercise of any power or
right preclude further exercise of that power or right.

         9. Maximum Rate. All agreements between the Maker and the holder
hereof, whether now existing or hereafter arising and whether written or oral,
are hereby expressly limited so that in no contingency or event whatsoever,
shall the amount paid, or agreed to be paid, to the holder hereof for the use,
forbearance, or detention of the funds advanced pursuant to this Note, or
otherwise, or for the payment or performance of any covenant or obligation
contained herein or any other document or instrument evidencing, securing, or
pertaining to this Note, exceed the maximum amount permissible under applicable
law (the "Maximum Rate"). If, from any circumstances whatsoever, fulfillment of
any provision hereof or of any other document or instrument exceeds the Maximum
Rate, then ipso facto, the obligation to be fulfilled shall be reduced to the
limit of such validity, and if from any such circumstances the holder hereof
shall ever receive anything of value deemed interest by applicable law which
would exceed interest at the highest lawful rate, such amount would be excessive
interest, and would be applied to the unpaid principal balance of this Note, or
on account of any other principal indebtedness of the Maker to the holder
hereof, and not to the payment of interest, or if such excessive interest
exceeds the unpaid principal balance of this Note and such other indebtedness,
such excess shall be refunded to the Maker. All sums paid, or agreed to be paid,
by the Maker for the use, forbearance, or detention of the indebtedness of the
Maker to the holder of this Note shall, to the extent permitted by applicable
law, be amortized, pro-rated, allocated, and spread throughout the full term of
such indebtedness until payment in full so that the actual rate of interest on
account of such indebtedness is uniform throughout the term hereof. The terms
and provisions of this paragraph shall control and supersede every other
provision of all agreements between the Maker and the holder hereof.

         10. Costs and Fees. If there is a Default under this Note, or if this
Note is placed in the hands of an attorney or agency for collection, regardless
of whether or not suit is filed, or if this Note is collected by suit or legal
process, including, but not limited to, through the probate court or bankruptcy
proceedings, Maker agrees to pay all costs of collection, including reasonable
attorney's fees and court costs in addition to other amounts due. Additionally,
Maker agrees to pay all reasonable attorney's fees and expenses of Payee and its
affiliates incurred in connection with the negotiation, preparation,
administration, enforcement and collection of this Note and the Loan Documents
immediately upon request thereof by Payee.
