UNIVERSAL NOTE
(c) 1984, 1991 BANKERS SYSTEMS, INC., ST. CLOUD MN (1-800-397-2341) FORM UN-TX 8/3/91               (page 1 of 2)
</TABLE>
                         
<PAGE>   2
APPLICABLE LAW:  The law of the state of Texas will govern this note.  Any term
of this note which is contrary to applicable law will not be effective, unless
the law permits you and me to agree to such a variation.  If any provision of
this agreement cannot be enforced according to its terms, this fact will not
affect the enforceability of the remainder of this agreement.  No modification
of this agreement may be made without your express written consent.  Time is of
the essence in this agreement.

PAYMENTS:  Each payment I make on this note will first reduce the amount I owe
you for charges which are neither interest nor principal.  The remainder of
each payment will then reduce accrued unpaid interest, and then unpaid
principal.  If you and I agree to a different application of payments, we will
describe our agreement on this note.  I may prepay a part of, or the entire
balance of this loan without penalty, unless we specify to the contrary on this
note.  Any partial prepayment will not excuse or reduce any later scheduled
payment until this note is paid in full (unless, when I make the prepayment,
you and I agree in writing to the contrary).

INTEREST:  If I receive the principal in more than one advance, each advance
will start to earn interest only when I receive the advance.  The interest rate
in effect on this note at any given time will apply to the entire principal
advanced at that time.  Notwithstanding anything to the contrary, I do not
agree to pay and you do not intend to charge any rate of interest that is
higher than the maximum rate of interest you could charge under applicable law
for the extension of credit that is agreed to here (either before or after
maturity).  If any notice of interest accrual is sent and is in error, we
mutually agree to correct it, and if you actually collect more interest than
allowed by law and this agreement, you agree to refund it to me.
        
INDEX RATE:  The index will serve only as a device for setting the rate on this
note.  You do not guarantee by selecting this index, or the margin, that the
rate on this note will be the same rate you charge on any other loans or class
of loans to me or other borrowers.

ACCRUAL METHOD:  The amount of interest that I will pay on this loan will be
calculated using the interest rate and accrual method stated on page 1 of this
note.  For the purpose of interest calculation, the accrual method will
determine the number of days in a "year."  If no accrual method is stated, then
you may use any reasonable accrual method for calculating interest.

POST MATURITY RATE:  For purposes of deciding when the "Post Maturity Rate"
(shown on page 1) applies, the term "maturity" means the date of the last
scheduled payment indicated on page 1 of this note or the date you accelerate
payment of the note, whichever is earlier.

SINGLE ADVANCE LOANS:  If this is a single advance loan, you and I expect
that you will make only one advance of principal.  However, you may add other
amounts to the principal if you make any payments described in the "PAYMENTS BY
LENDER" paragraph below.

MULTIPLE ADVANCE LOANS:  If this is a multiple advance loan, you and I expect
that you will make more than one advance of principal.  If this is closed end
credit, repaying a part of the principal will not entitle me to additional
credit. 

PAYMENTS BY LENDER:  If you are authorized to pay, on my behalf,
charges I am obligated to pay (such as property insurance premiums), then you
may treat those payments made by you as advances and add them to the unpaid
principal under this note, or you may demand immediate payment of the charges.

SET-OFF:  I agree that you may set off any amount due and payable under this
note against any right I have to receive money from you.

         "Right to receive money from you" means:

         (1)  any deposit account balance I have with you;

         (2)  any money owed to me on an item presented to you or in your
              possession for collection or exchange; and
  
         (3)  any repurchase agreement or other nondeposit obligation.

         "Any amount due and payable under this note" means the total amount of
which you are entitled to demand payment under the terms of this note at the
time you set off.  This total includes any balance the due date for which you
properly accelerate under this note.

         If my right to receive money from you is also owned by someone who has
not agreed to pay this note, your right of set-off will apply to my interest in
the obligation and to any other amounts I could withdraw on my sole request or
endorsement.  Your right of set-off does not apply to an account or other
obligation where my rights are only as a representative.  It also does not
apply to any Individual Retirement Account or other tax-deferred retirement
account.

         You will not be liable for the dishonor of any check when the dishonor
occurs because you set off this debt against any of my accounts.  I agree to
hold you harmless from any such claims arising as a result of your exercise of
your right of set-off.

REAL ESTATE OR RESIDENCE SECURITY:  If this note is secured by real estate or a
residence that is personal property, the existence of a default and your
remedies for such a default will be determined by applicable law, by the terms
of any separate instrument creating the security interest and, to the extent not
prohibited by law and not contrary to the terms of the separate security
instrument, by the "Default" and "Remedies" paragraphs herein.  

DEFAULT:  I will be in default on this loan and any agreement securing this
loan if any one or more of the following occurs:

         (1)     I fail to perform any obligation which I have undertaken in
                 this note or any agreement securing this note; or

         (2)     you, in good faith, believe that the prospect of payment or
                 the prospect of my performance of any other of my obligations
                 under this note or any agreement securing this note is
                 impaired.

         If any of us are in default on this note or any security agreement,
you may exercise your remedies against any or all of us.

REMEDIES:  If I am in default on this note you have, but are not limited to, the
following remedies:

         (1)     You may demand immediate payment of my debt under this note
                 (principal, accrued unpaid interest and other accrued charges).

         (2)     You may set off this debt against any right I have to the
                 payment of money from you, subject to the terms of the
                 "Set-Off" paragraph herein.

         (3)     You may demand security, additional security, or additional
                 parties to be obligated to pay this note as a condition for 
                 not using any other remedy.

         (4)     You may refuse to make advances to me or allow purchases on
                 credit by me.

         (5)     You may use any remedy you have under state or federal law.

         By selecting any one or more of these remedies you do not give up your
right to later use any other remedy.  By waiving your right to declare an event
to be a default, you do not waive your right to later consider the event as a
default if it continues or happens again.

COLLECTION COSTS AND ATTORNEY'S FEES:  I agree to pay all costs of collection,
replevin or any other or similar type of cost if  I am in default.  In
addition, if  you hire an attorney to collect this note, I also agree to pay
any fee you incur with such attorney plus court costs (except where prohibited
by law).  To the extent permitted by the United States Bankruptcy Code, I also
agree to pay the reasonable attorney's fees and costs you incur to collect this
debt as awarded by any court exercising jurisdiction under the Bankruptcy Code.

WAIVER:  I give up my rights to require you to do certain things.  I will not
require you to:

         (1)     demand payment of amounts due (presentment);

         (2)     obtain official certification of nonpayment (protest);

         (3)     give notice that amounts due have not been paid (notice of
                 dishonor);

         (4)     give notice of intent to accelerate; or

         (5)     give notice of acceleration.

OBLIGATIONS INDEPENDENT:  I understand that I must pay this note even if
someone else has also agreed to pay it (by, for example, signing this form or a
separate guarantee or endorsement).  You may sue me alone, or anyone else who
is obligated on this note, or any number of us together, to collect this note.
You may do so without any notice that it has not been paid (notice of
dishonor).  You may without notice release any party to this agreement without
releasing any other party.  If you give up any of your rights, with or without
notice, it will not affect my duty to pay this note.  Any extension of new
credit to any of us, or renewal of this note by all or less than all of us
will not release me from my duty to pay it.  (Of course, you are entitled to
only one payment in full.) I agree that you may at your option extend this note
or the debt represented by this note, or any portion of the note or debt, from 
time to time without limit or notice and for any term without affecting my 
liability for payment of the note.  I will not assign my obligation under this
agreement without your prior written approval.  

CREDIT INFORMATION:  I agree and authorize you to obtain credit information 
about me from time to time (for example, by requesting a credit report) and to 
report to others your credit experience with me (such as a credit reporting
agency).  I agree to provide you, upon request, any financial statement or
information you may deem necessary. I warrant that the financial statements and
information I provide to you are or will be accurate, correct and complete.

NOTICE:  Unless otherwise required by law, any notice to me shall be given by
delivering it or by mailing it by first class mail addressed to me at my last
known address.  My current address is on page 1.  I agree to inform you in
writing of any change in my address.  I will give any notice to you by mailing
it first class to your address state on page 1 of this agreement, or to any
other address that you have designated.
