It is the intent of Maker and Payee
in the execution of this Note and all other loan documents to contract in strict
compliance with applicable usury law. In furtherance thereof, Maker and Payee
stipulate and agree that none of the terms and provisions contained in this
Note, or in any other instrument executed in connection herewith, shall ever be
construed to create a contract to pay for the use, forbearance or detention of
money, interest at a rate in excess of the maximum rate allowedbylaw ("Maximum Rate"). Neither Maker nor any
guarantors, endorsers or other parties now or hereafterbecomingliable for payment of this Note
shall ever be obligated or required to pay interest on this Note at a rate in
excess of the Maximum Rate, and the provisions of this paragraph shall control
over all other provisions of this Note and any other loan documents now or
hereafter executed which may be in apparent conflict herewith. Payee expressly
disavows any intention to charge or collect excessive unearned interest or
finance charges in the event the maturity of this Noteisaccelerated. If the maturity of
this Note shall be accelerated for any reason or if the principal of this Note
is paid prior to the end of the term of this Note, and as a result thereof the
interest received for the actual period of existence of the loan evidenced by
this Note exceeds the applicable maximum lawful rate, the holder of this Note
shall credit the amount of such excess against the principal balance of this
Note then outstanding and thereby shall render inapplicable any and all
penalties of any kind provided by applicable law as a result of such excess
interest; provided, however, that if the principal hereof has been paid in full,
such excess shall be refunded to Maker. If the holder of this Note shall receive
money (or anything else) which is determined to constitute interest and which
would increase the effective interest rate on this Note or any other
indebtedness which Maker or a guarantor is obligated to pay to holder to a rate
in excess of that permitted by applicable law, the amount determined to
constitute interest in excess of the lawful rate shall be credited against the
principal balance of this Note then outstanding or, if the principal balance has
been paid in full, refunded to Maker, in which event any and all penalties of
any kind under applicable law as a result of such excess interest shall be
inapplicable. If the holder of this Note shall not actually receive, but shall
contract for, request or demand, a payment of money (or anything else) which is
determined to constitute interest and which would increase the effective
interest rate contracted for or charged on this Note or the other indebtedness
evidenced or secured by the Loan Documents to a rate in excess of that permitted
by applicable law, the holder of this Note shallbeentitled, following such
determination, to waive or rescind the contractual claim, request or demand for
the amount determined to constitute interest in excess of the lawful rate, in
which event any and all penalties of any kind under applicable law as a result
of such excess interest shall be inapplicable. By execution of this Note, Maker
acknowledges that Maker believes the loan evidencedbythis Note to be non-usurious and agrees that if, at
any time, Maker should have reason to believe that such loan is in fact
usurious, Maker will give the holder of this Note notice of
such condition and Maker agrees that the holder shall have sixty (60) daysinwhich to make appropriate refund or
other adjustment in order to correct such condition if in fact such
exists.

Additionally,
if, from any circumstance whatsoever, fulfillment of any provision hereof or of
any documents or instruments executed pursuant to the terms thereof, shall, at
the time fulfillment of such provision be due, involve transcending the Maximum
Rate then, ipso facto, the obligation to be fulfilled shall be reduced to the
Maximum Rate. The term "applicable law" as used in this Note shall mean the laws
of the State of Texas or the laws of the United States, whichever laws allow the
greater rate of interest, as such laws now exist or may be changed or amended or
come into effect in the future.




Company
agrees to make lump sum payments if it receives any substantial payments from
any sources.




This
Note is secured under the terms of a Security Agreement dated the date hereof,
executed by Maker (or by any other liable party) in favor of Payee, or any other
holder of this Note.




In
addition to the above provisions, Maker will be in default if : (1) Maker fails
to timely pay or perform any obligation or covenant in any written agreement
between Payee and Maker; (2) Maker makes any material false statement or
representation in any agreement or document presented to Payee and upon which
Payee relied in funding this Note; (3) a receiver is appointed for Maker; (4)
bankruptcy or insolvency proceedings are commenced against or by Maker; (5)
Maker is dissolved; (6)Maker's collateral provided to secure payment of this
Note is impaired by loss, theft, damage, levy and execution, or destruction,
unless it is promptly replaced with collateral of like kind and quality or
restored to its former condition.




This
Note shall rank senior to all other indebtedness of Maker, and no other
obligation may be created by Maker that ranks senior to this Note.




This
Note has been executed and delivered in and shall be construed in accordance
with and governed by the laws of the State of Texas.
