|GRAPHIC |  | Amended and Restated Variable Rate-Installment Note
|------- |  | ---------------------------------------------------

|             
|-------------
|AMOUNT       
|$5,000,000.00
|             

FOR VALUE RECEIVED, the undersigned promise(s) to pay to the order of COMERICA BANK-TEXAS, a Texas
banking association ("Bank"), at any office of the Bank in the State of Texas, Five Million and No/100 Dollars (U.S. $5,000,000) plus interest on the unpaid balance from the date of this Note at a per
annum rate equal to the lesser of (a) the Maximum Rate, as later defined, or (b) the Stated Rate, as later defined, until maturity, whether by acceleration or otherwise. If on any day
the Stated Rate shall exceed the Maximum Rate for that day, the rate of interest applicable to this Note shall be fixed at the Maximum Rate on that day and on each day thereafter until the total
amount of interest accrued on the unpaid principal balance of this Note equals the total amount of interest which would have accrued if there had been no Maximum Rate. Subject to the limitations
hereinbelow set forth, interest shall be calculated for the actual number of days the principal is outstanding on the basis of a 360-day year if this Note evidences a business or
commercial loan. The Stated Rate shall mean the Bank's "prime rate," which is the annual rate of interest so designated by the Bank and which is changed by the Bank from time to time, plus four
percent (4%). Interest rate changes will be effective for interest computation purposes as and when the Maximum Rate or the Stated Rate, as applicable, changes.

Reference
is made to that certain Second Amended and Restated Revolving Credit Loan Agreement dated as of November 26, 2002 executed between the undersigned and the Bank (as the same may be
amended, restated or modified from time to time, the "Loan Agreement"). Unless otherwise defined herein, capitalized terms herein shall have the meanings given such terms in the Loan Agreement. This
Note is the Term Note referred to in the Loan Agreement.

Notwithstanding
the foregoing, (i) upon the occurrence of an Event of Default, or (ii) after the earlier of acceleration or the Term Loan Termination Date, interest on the unpaid
principal balance of this Note shall accrue and be paid at the Default Rate.

Accrued
and unpaid interest on the unpaid principal balance of this Note shall be due and payable under this Note on the first (1st) day of each month, commencing May 1, 2003, and continuing on
the same day of each successive month thereafter through and including the Term Loan Termination Date. In addition to (and not in lieu of) the required monthly installments of interest to be paid as
set forth in this Note, the undersigned shall pay the following amounts, in each case, to be credited to the unpaid principal balance of this Note:

On
or before April 15, 2003, an installment in the amount of $1,000,000;and additionally,



The
term "Maximum Rate," as used herein, shall mean at the particular time in question the maximum nonusurious rate of interest which, under applicable law, may then be charged on this Note. If such
maximum rate of interest changes after the date hereof, the Maximum Rate shall be automatically increased or decreased, as the case may be, without notice to the undersigned from time to time as of
the effective date of each change in such maximum rate.

If
this Note or any installment under this Note shall become payable on a day other than a day on which the Bank is open for business, this payment may be extended to the next succeeding business day
and interest shall be payable at the rate specified in this Note during this extension. Any payments of principal in excess of the installment payments required under this Note need not be accepted by
the Bank (except as required under applicable law), but if accepted shall apply to the installments last falling due. A late installment charge equal to a reasonable amount not to exceed 5% of each
late installment may be charged on any installment payment not received by the Bank within 10 calendar days after the installment due date, but acceptance of payment of this charge shall not waive any
Default under this Note.

This
Note and any other indebtedness and liabilities of any kind of the undersigned (or any of them) to the Bank (including without limitation that certain Amended and Restated Revolving Credit Note
dated as of November 26, 2002 in the original aggregate principal amount of $3,000,000 executed by the undersigned in favor of the Bank, as the same may be amended, restated, increased,
extended or otherwise modified from time to time), and any and all modifications, renewals or extensions of it, whether joint or several, contingent or absolute, now existing or later arising, and
however evidenced and whether incurred voluntarily or involuntarily, known or unknown, or originally payable to the Bank or to a third party and subsequently acquired by Bank including, without
limitation, any late charges; loan fees or charges; overdraft indebtedness; costs incurred by Bank in establishing, determining, continuing or defending the validity or priority of any security
interest, pledge or other lien or in pursuing any of its rights or remedies under any loan document (or otherwise) or in connection with any proceeding involving the Bank as a result of any financial
accommodation to the undersigned (or any of them); and reasonable costs and expenses of attorneys and paralegals, whether inside or outside counsel is used, and whether any suit or other action is
instituted, and to court costs if suit or action is instituted, and whether any such fees, costs or expenses are incurred at the trial court level or on appeal, in bankruptcy, in administrative
proceedings, in probate proceedings or otherwise (collectively "Indebtedness") are secured by and the Bank is granted a security interest in and lien upon all items deposited in any account of any of
the undersigned with the Bank and by all proceeds of these items (cash or otherwise), all account balances of any of the undersigned from time to time with the Bank, by all property of any of the
undersigned from time to time in the possession of the Bank and by any

2

---

other collateral, rights and properties described in each and every deed of trust, mortgage, security agreement, pledge, assignment and other agreement which has been, or will at any time(s) later
be, executed by any (or all) of the undersigned to or for the benefit of the Bank (collectively "Collateral").

If
an Event of Default (as defined in the Loan Agreement) occurs, or if the undersigned (or any of them) or any guarantor under a guaranty of all or part of the Indebtedness ("guarantor")
(i) fail(s) to pay this Note or any of the Indebtedness when due, by maturity, acceleration or otherwise, or fail(s) to pay any Indebtedness owing on a demand basis upon demand; or

pledge, collateral assignment or subordination agreement relating to all or any part of the Indebtedness; or (c) if there is any failure by any of the undersigned or any guarantor to pay when

at its option and without prior notice to the undersigned (or any of them), declare any or all of the Indebtedness to be immediately due and payable (notwithstanding any provisions contained in the
evidence thereof to the contrary), sell or liquidate all or any portion of the Collateral, set off against the Indebtedness any amounts owing by the Bank to the undersigned (or any of them), charge
interest at the default rate provided in the document evidencing the relevant Indebtedness and exercise any one or more of the rights and remedies granted to the Bank by any agreement with the
undersigned (or any of them) or given to it under applicable law. All payments under this Note shall be in immediately available United States funds, without setoff or counterclaim.

If
this Note is signed by two or more parties (whether by all as makers or by one or more as an accommodation party or otherwise), the obligations and undertakings under this Note shall be that of all
and any two or more jointly and also of each severally. This Note shall bind the undersigned, and the undersigned's respective heirs, personal representatives, successors and assigns.

The
undersigned waive(s) presentment, demand, protest, notice of dishonor, notice of demand or intent to demand, notice of acceleration or intent to accelerate, and all other notices and agree(s) that
no extension or indulgence to the undersigned (or any of them) or release, substitution or nonenforcement of any security, or release or substitution of any of the undersigned, any guarantor or any
other party, whether with or without notice, shall affect the obligations of any of the undersigned. The undersigned waive(s) all defenses or right to discharge available under Section 3.605 of
the Texas Uniform Commercial Code and waive(s) all other suretyship defenses or right to discharge. The undersigned agree(s) that the Bank has the right to sell, assign, or grant participations or any
interest in, any or all of the Indebtedness, and that, in connection with this right, but without limiting its ability to make other disclosures to the full extent allowable, the Bank may disclose all
documents and information which the Bank now or later has relating to the undersigned or the Indebtedness. The undersigned agree(s) that the Bank may provide information relating to this Note or the
Indebtedness or relating to the undersigned to the Bank's parent, affiliates, subsidiaries and service providers.

The
undersigned agree(s) to reimburse the holder or owner of this Note upon demand for any and all costs and expenses (including without limit, court costs, legal expenses and reasonable attorneys'
fees, whether inside or outside counsel is used, and whether or not suit is instituted and, if suit is instituted, whether at the trial court level, appellate level, in a bankruptcy, probate or
administrative proceeding or otherwise) incurred in collecting or attempting to collect this Note or incurred in any other matter or proceeding relating to this Note.

The
undersigned acknowledge(s) and agree(s) that there are no contrary agreements, oral or written, establishing a term of this Note and agree(s) that the terms and conditions of this Note may not be
amended, waived or modified except in a writing signed by an officer of the Bank expressly stating that the writing constitutes an amendment, waiver or modification of the terms of this Note. As used
in this Note, the word "undersigned" means, individually and collectively, each maker, accommodation party, indorser and other party signing this Note in a similar capacity. If any provision of this
Note is unenforceable in whole or part for any reason, the remaining provisions shall continue to be effective. THIS NOTE IS MADE IN THE STATE OF TEXAS AND SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

This
Note and all other documents, instruments and agreements evidencing, governing, securing, guaranteeing or otherwise relating to or executed pursuant to or in connection with this Note or the
Indebtedness evidenced hereby (whether executed and delivered prior to, concurrently with or subsequent to this Note), as such documents may have been or may hereafter be amended from time to time
(the "Loan Documents") are intended to be performed in accordance with, and only to the extent permitted by, all applicable usury laws. If any provision hereof or of any of the other Loan Documents or
the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision to any other person or
circumstance nor the remainder of the instrument in which such provision is contained shall be affected thereby and shall be enforced to the greatest extent permitted by law. It is expressly
stipulated and agreed to be the intent of the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable on the indebtedness
evidenced by this Note. If the applicable law is ever revised, repealed or judicially interpreted so as to render usurious any amount called for under this Note or under any of the other Loan
Documents, or contracted for, charged, taken, reserved or received with respect to the indebtedness evidenced by this Note, or if Bank's exercise of the option to accelerate the maturity of this Note,
or if any prepayment by the undersigned or prepayment agreement results (or would, if complied with, result) in the undersigned having paid, contracted for or being charged for any interest in excess
of that permitted by law, then it is the express intent of the undersigned and Bank that this Note and the other Loan Documents shall be limited to the extent necessary to prevent such result and all
excess amounts theretofore collected by Bank shall be credited on

3

---

the principal balance of this Note or, if fully paid, upon such other Indebtedness as shall then remaining outstanding (or, if this Note and all other Indebtedness have been paid in full, refunded to
the undersigned), and the provisions of this Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the
necessity of the execution of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder or thereunder. All
sums paid, or agreed to be paid, by the undersigned for the use, forbearance, detention, taking, charging, receiving or reserving of the indebtedness of the undersigned to Bank under this Note or
arising under or pursuant to the other Loan Documents shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such
indebtedness for so long as such indebtedness is outstanding. To the extent federal law permits Bank to contract for, charge or receive a greater amount of interest, Bank will rely on federal law
instead of the Texas Finance Code, as supplemented by Texas Credit Title, for the purpose of determining the Maximum Rate. Additionally, to the maximum extent permitted by applicable law now or
hereafter in effect, Bank may, at its option and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code, as supplemented by Texas Credit Title, or
under other applicable law, by giving notice, if required, to the undersigned as provided by applicable law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in
any of the other Loan Documents, it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the
time of such acceleration.

The
indebtedness evidenced by this Note is in renewal, extension, and modification, but not in extinguishment or novation of the indebtedness evidenced by that certain Variable
Rate-Installment Note dated November 26, 2002 in the original principal amount of $5,000,000 executed by the undersigned and payable to the order of the Bank.

THE
UNDERSIGNED AND THE BANK, BY ACCEPTANCE OF THIS NOTE, ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR HAVING HAD
THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE
PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS.

THIS WRITTEN LOAN AGREEMENT (AS DEFINED BY SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE) REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
