         If any payment required to be made hereunder becomes due and payable on
a nonbusiness day, the maturity thereof shall extend to the next business day.
The term "business day" shall mean a calendar day excluding Saturdays, Sundays
or other days on which banks in the State of Texas are required or authorized to
remain closed.

         If this Note is placed in the hands of an attorney for collection, the
Company agrees to pay attorneys' fees and costs and expenses of collection,
including but not limited to court costs.

         An Event of default is defined as (i) the failure of prompt and timely
payment when due of any installment of Stated Interest, Additional Interest or
principal under this Note, such failure continuing for thirty (30) calendar days
after notice thereof from Payee to Company, or (ii) the Company is adjudicated a
bankrupt, declared insolvent or shall execute a general assignment for the
benefit of creditors, or the Company shall file a voluntary petition in
bankruptcy or all, or substantially all of its assets shall become subject to
the control of a receiver and such receivership proceedings are not dismissed

then the Payee, at its option, may declare the entire unpaid balance of
principal, accrued State interest accrued Additional Interest hereunder to be
immediately due and payable.

         This Note shall be governed by and construed in accordance with the
laws of the State of Texas and applicable laws of the United States.

         In no contingency or event whatsoever shall the amount of interest paid
or agreed to be paid by the Company, received by payee, or requested or demanded
to be paid by the Company exceed the maximum amount permitted by applicable law.
In the event any such sums paid to Payee by the Company would exceed the maximum
amount permitted by applicable law, Payee shall automatically apply such excess
to the unpaid principal amount of this Note. All sums paid or agreed to be paid
by the Company, received by payee, or requested or demanded to be paid by the
Company, which are, or hereafter may be construed to be, or in respect of
compensation, for the use, forbearance or detention of money shall, to the
extent permitted by applicable law, be amortized, prorated spread and allocated
throughout the full term of all indebtedness of the Company to Payee, to the end
that the actual rate of interest hereon shall never exceed the maximum rate of
interest permitted from time to time by applicable law.
