Borrower in accordance with their terms, except as such enforceability may be

affecting creditors' rights and the enforcement of debtors' obligations
generally and by general principles of equity, regardless of whether enforcement
is pursuant to a proceeding in equity or at law.

     3.3. Absence of Conflicts. The execution, delivery and performance of this
Agreement is not in conflict with nor constitutes a breach of any provision
contained in Borrower's organizational documents, nor will it constitute an
event of default under any material agreement to which Borrower is a party or by
which Borrower is bound.

     3.4. Consents and Approvals. Borrower has obtained all consents, approvals
and authorizations of, made all declarations or filings with, and given all

affect Borrower in, conducting its businesses in any jurisdiction in which it is
now conducting business. As defined in this Agreement, "Knowledge" of Borrower

years and (b) all of its Quarterly Reports on Form 10-Q and each other report,
registration statement or definitive proxy statement filed with the Securities
and Exchange Commission since the beginning of such two fiscal years
(collectively, the "SEC Reports"). The SEC Reports do not (as of their
respective dates) contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were

in such Financial Statements or the notes thereto) and fairly present the
financial position

<PAGE>

           (f) A final judgment for the payment of money in an amount in excess
of $50,000 shall be rendered against Borrower (other than any judgment as to
which a reputable insurance company shall have accepted full liability in
writing) and shall remain undischarged for a period (during which execution
shall not be effectively stayed) of 20 days after the date on which the right to
appeal has expired;

           (g) Any representation or warranty made by Borrower in this
Agreement, the Security Agreement or in any other document or instrument
furnished in connection with the transactions contemplated hereby shall prove to
be materially false or incorrect on the date as of which made; or

           (h) An event shall occur or there exist facts or circumstances which
create or result in a Material Adverse Effect;

then and in any such case (x) upon the occurrence of any Event of Default
described in paragraphs (d) or (e), the unpaid principal amount of and accrued
interest on the Notes shall automatically become due and payable, without
presentment, demand, protest or notice of any kind, all of which are hereby
waived by Borrower, and (y) upon the occurrence of any other Event of Default,
in addition to any other rights, powers and remedies permitted by law or in
equity, the Lenders may, at their option, by notice in writing to Borrower,
declare the Notes to be, and the Notes shall thereupon be and become,
immediately due and payable, together with interest accrued thereon and all
other sums due hereunder, without presentment, demand, protest or other notice
of any kind, all of which are waived by Borrower.

     Upon the occurrence of any Event of Default, the holders of the Notes may
proceed to protect and enforce their rights by an action at law, suit in equity
or other appropriate proceeding, whether for the specific performance of any
agreement contained herein or in the Note held by them, for an injunction
against a violation of any of the terms hereof or thereof, or for the pursuit of
any other remedy which it may have by virtue of this Agreement, the Security
Agreement or pursuant to applicable law. Borrower shall pay to the holders of
the Notes upon demand the reasonable costs and expenses of collection and of any
other actions referred to in this Article, including without limitation
reasonable attorneys' fees, expenses and disbursements.

     No course of dealing and no delay on the part of the holders of the Notes
in exercising any of their rights shall operate as a waiver thereof or otherwise
prejudice the rights of such holders, nor shall any single or partial exercise
of any right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder. No right, power or
remedy conferred hereby or by the Notes on the holders thereof shall be
exclusive of any other right, power or remedy referred to herein or therein or
now or hereafter available at law, in equity, by statute or otherwise.

be liable for all commercially reasonable costs, expenses and attorneys' fees
incurred by the Lender in connection with the collection of the indebtedness
evidenced by the Note.

     To the extent permitted by applicable law, the Borrower waives all rights

     The term "the Borrower" shall include each person and entity now or
hereafter liable hereunder, whether as maker, successor, assignee or endorsee,
each of whom shall be jointly, severally and primarily liable for all of the
obligations set forth herein.

     If any provision of this Note shall for any reason be held invalid or
unenforceable, such invalidity or unenforceability shall not affect any other
provision of this Note, but this Note shall be construed as if this Note had
never contained the invalid or unenforceable provision.
