8.   Miscellaneous.

     8.1     No Waiver. No failure to exercise and no delay on the part of the
Lender in exercising any power or right in connection herewith or under any
other Loan Document shall operate as a waiver, nor shall any single or partial
exercise of any such right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. No course of dealing
between the Borrower and the Lender shall operate as a waiver of any right of
the Lender. No modification or waiver of any provision of this Agreement or any
other Loan Document shall be effective unless the same shall be in writing and
signed by the Person against whom enforcement thereof is to be sought.

     8.2     Governing Law. Unless otherwise specified therein, each Loan
Document shall be governed by and construed in accordance with the laws of the
State of Texas and The United States of America. The Parties hereby irrevocably
agree that any legal proceeding against the Lender arising out of or in
connection with this Agreement or the other Loan Documents shall be brought in
the District Courts of Travis County, Texas, or in the United States District
Court for the Western District of Texas, Austin Division.

     8.3     Usury Not Intended; Refund of Any Excess Payments. It is the intent
of the Parties in the execution and performance of this Agreement to contract in
strict compliance with the usury laws of the State of Texas and The United
States of America from time to time in effect. In furtherance thereof, the
Lender and the Parties stipulate and agree that none of the terms and provisions
contained in this Agreement or the other Loan Documents shall ever be construed
to create a contract to pay for the use, forbearance, or detention of money with
interest at a rate in excess of the Highest Lawful Rate and that for purposes
hereof "interest" shall include the aggregate of all charges which constitute
interest under such laws that are contracted for, reserved, taken, charged, or
received under this Agreement. In determining whether or not the interest paid
or payable, under any specific contingency, exceeds the Highest Lawful Rate, the
Parties and the Lender shall, to the maximum extent permitted under applicable
law, (a) treat all advances as but a single extension of credit (and the Parties
and the Lender agree that such is the case and that provision herein for
multiple advances is for convenience only), (b) characterize any nonprincipal
payment as an expense, fee, or premium rather than as interest, (c) exclude
voluntary prepayments and the effects thereof, and (d) "spread" the total amount
of interest throughout the entire contemplated term of the Loan. The provisions
of this paragraph shall control over all other provisions of the Loan Documents
which may be in apparent conflict herewith.

     8.4     Expenses. Any provision to the contrary notwithstanding, and
whether or not the transactions contemplated by this Agreement shall be
consummated, the Parties shall pay on demand all reasonable out-of-pocket
expenses (including, without limitation, the fees and expenses of counsel for
the Lender) in connection with the negotiation, preparation,



execution, filing, recording, refiling, re-recording, modification,
supplementing, and waiver of the Loan Documents and the making and collection of
the Loan. The obligations of the Parties under this and the following section
shall survive the termination of this Agreement and/or the payment of the Loan.

     8.5     Indemnification. The Borrower agrees to indemnify, defend, and hold
the Lender harmless from and against any and all loss, liability, obligation,
damage, penalty, judgment, claim, deficiency, and expense (including interest,
penalties, attorneys' fees, and amounts paid in settlement) to which the Lender
may become subject arising out of or based upon the Loan Documents or the Loan,
excluding those to the extent caused by the Lender's own acts or omissions.

     8.6     Entire Agreement. This Agreement and the Loan Documents embody the
entire Agreement and understanding between the Parties and the Lender relating
to the subject matter hereof and supersedes all prior proposals, negotiations,
agreements, and understandings relating to such subject matter. The Parties
certify that they are not relying on any representation, warranty, covenant, or
agreement except for those set forth in this Agreement and the other Loan
Documents. All written representations made by the Parties to the Lender
respecting the subject matter hereof shall survive the execution of this
Agreement.

     8.7     Severability. If any provision of any Loan Document shall be
invalid, illegal, or unenforceable in any respect under any applicable law, the
validity, legality, and enforceability of the remaining provisions shall not be
affected or impaired thereby.

     8.8     Loan Agreement Controls. If there are any conflicts or
inconsistencies among this Agreement and any of the other Loan Documents, this
Agreement shall prevail and control.

     8.9     Commitment. The Lender has no commitment to lend sums to the
Borrower other than as specifically set forth herein.

     8.10    Notices. All notices, demands and requests made under any provision
of this Agreement shall be in writing and shall be deemed to have been properly
delivered as of the time of delivery if personally delivered, the date of
receipt or refusal indicated on the return receipt, if sent by United States
certified mail, return receipt requested, and postage prepaid, or one (1)
business day after the time of delivery to Federal Express (or comparable
express delivery system) if sent by such method with all costs prepaid. All
notices, demands and requests shall be addressed to the Lender at 500 Marquette
NW, 14th Floor, Albuquerque, New Mexico 87102, Attention: Elizabeth Allbright,
to the Borrower at 2700 Pecan Street West, Suite 423, Pflugerville, Texas 78660,
Attention: William Jasura, Chief Financial Officer, or to such other address
that either the Lender or the Borrower may designate to the other by written
notice sent in the manner required hereby.

     8.11    Sale or Assignment. The Lender reserves the right, in its sole
discretion, without notice to the Borrower, or any of the other Parties, to sell
participants or assign its interest, or both, in all or any part of the Loan
evidenced by this Agreement, or the other Loan



Documents. No such sale or assignment shall relieve the Lender of any obligation
of the Lender under the Loan Documents.

Exhibit A - Note



PROMISSORY NOTE

$10,000,000.00                                                   August 9, 2002

     For value received, WINDERMERE UTILITY CO., INC., a Texas corporation (the
"Makers," whether one or more), promise to pay to the order of BANK OF THE WEST
(the "Lender"), at 500 Marquette NW, 14th Floor, Albuquerque, New Mexico 87102,
or such other location as the Lender designates to the makers in writing, the
principal sum of TEN MILLION AND NO/100 DOLLARS ($10,000,000.00), or the
outstanding principal amount advanced hereunder, whichever is less, in legal and
lawful money of the United States of America, with interest thereon as
hereinafter specified.

TERMS OF PAYMENT:

     Principal shall be due and payable in quarterly installments of $125,000.00
each, commencing on November 9, 2002 and continuing thereafter on February 9,
May 9, August 9 and November 9 of each year until August 9, 2012 (the "Maturity
Date"), when the entire amount hereof, principal and interest then remaining
unpaid, shall be then due and payable. Interest, computed upon the unpaid
principal balance hereof, shall be due and payable quarterly as it accrues, on
the same dates as, but in addition to, said payments of principal; interest
being calculated on the unpaid principal to the date each payment is received
and the payment made credited first to the discharge of the interest accrued and
the balance to the reduction of the principal.

PAYMENT ON NON-BUSINESS DAYS:

     If any payment hereunder falls due on a Saturday, Sunday or public holiday
on which commercial banks in Albuquerque, New Mexico are permitted or required
by law to be closed, the time for such payment shall be extended to the next day
on which the Lender is open for business, and such extension of time shall be
included in the calculation of interest accruing and payable hereunder.

LATE PAYMENT CHARGE:

     The Makers agree to pay to the Lender a late payment service charge in an
amount equal to five percent (5%) of any regularly scheduled principal and
accrued interest installment which is not received by the Lender within fifteen
(15) days after the installment is due; provided however, such late payment
service charge shall not apply to the principal and interest installment due on
the Maturity Date.

RATE OF INTEREST:

     Prior to maturity (whether by acceleration or otherwise) interest on the
outstanding and unpaid principal balance hereof shall be computed in accordance
with the specific



provisions of the Loan Agreement dated of even date herewith between the Makers
and the Lender (the "Loan Agreement").

INTEREST AFTER DEFAULT:

     Upon default, including failure to pay upon final maturity, the Lender, at
its option, may, if permitted under applicable law, increase the variable
interest rate on this Note to six percent (6.00%) over the Adjusted LIBOR, as
defined in the Loan Agreement (the "Past Due Rate"). The interest rate will not
exceed the Maximum Lawful Rate permitted by applicable law. Prior to maturity,
the Past Due Rate shall not be charged on any balance owed under the Note after
the Borrower successfully cures any default in accordance with the express
notice and cure rights described in this Note.

     As used herein, the term "Maximum Lawful Rate" shall mean the greater of
(i) the highest non-usurious rate of interest permitted by applicable United
States law, or (ii) a rate per annum equal to the applicable weekly ceiling
described in Chapter 303 of the Texas Finance Code, as amended, as such weekly
ceiling is in effect from time to time, but in no event greater than
twenty-eight percent (28.00%) per annum. Unless precluded by law, changes in the
Maximum Lawful Rate created by statute or governmental action during the term of
this Note shall be immediately applicable to this Note on the effective date of
such changes. If the applicable law ceases to provide for a Maximum Lawful Rate,
the Maximum Lawful Rate shall be equal to eighteen percent (18%) per annum.

PREPAYMENT:

     Prior to August 9, 2007, the Borrower shall only have the right to prepay
this Note upon payment of a prepayment premium to the Lender on the date of the
prepayment. The prepayment premium shall be equal to two percent (2.00%) of the
unpaid principal balance of this Note if made prior to August 9, 2005 and one
percent (1.00%) of the unpaid principal balance of this Note if made between
August 9, 2005 and August 9, 2007.

     At any other time, the Makers reserve the right to prepay this Note or any
portion hereof without penalty or premium; however, all prepayments must be made
at the end of the applicable Interest Period (as defined in the Loan Agreement).
Interest shall be calculated on the unpaid principal to the date of any
prepayment and any such prepayment shall be applied first toward the payment of
accrued interest and next to the principal installments of this Note in the
direct order of maturity beginning with the earliest date.

SECURITY FOR PAYMENT:

     Payment of this Note is secured by, and this Note is entitled to the
benefits of, all security agreements, assignments, deeds of trust, mortgages and
lien instruments executed by the Makers (or any of them), or other similar
instruments, guaranties, endorsements or other agreements, executed by any other
person or entity (the "Collateral Agreements," whether one or more) to secure,
guarantee or otherwise provide for the payment hereof, in favor of or for the
benefit of the Lender, including any previously executed and any now or
hereafter



executed. Without limiting the foregoing, the Collateral Agreements include (i)
a Deed of Trust, Security Agreement and Financing Statement dated of even date
herewith executed by the Makers to Meade Bauer, Trustee for the benefit of the
Lender, which instrument covers certain real property (the "Real Property")
located in Travis and Williamson Counties, Texas, and (ii) a security agreement
dated of even date herewith executed by the Makers, as debtor, in favor of the
Lender, as secured party, covering certain collateral as more particularly
described therein.

USE OF PROCEEDS:

     This Note represents funds advanced and to be advanced to the Makers at the
Makers' special instance and request, the receipt of a portion which is hereby
acknowledged, which funds are to refinance certain improvements on the Real
Property pursuant to the terms of the Loan Agreement.

REPRESENTATIONS AND WARRANTIES:

     WINDERMERE UTILITY CO., INC. expressly represents and warrants to the
Lender that it is a corporation duly organized and existing in good standing
under the laws of the State of Texas; that it possesses full power and authority
to conduct its business as now conducted and as presently proposed to be
conducted; that the execution and delivery of this Note will not contravene any
provisions of its articles of incorporation or by-laws; that the officer
executing this Note is the legally elected, qualified and acting officer of said
corporation and is expressly authorized to execute this Note by resolution of
the board of directors of said corporation.

LIMITATION OF INTEREST:

     All agreements and transactions among the Makers and the Lender, whether
now existing or hereafter arising, whether contained herein or in any other
instrument, and whether written or oral, are hereby expressly limited so that in
no contingency or event whatsoever, whether by reason of acceleration of the
maturity hereof, late payment, prepayment, or otherwise, shall the amount of
interest contracted for, charged or received by the Lender from the Makers for
the use, forbearance, or detention of the principal indebtedness or interest
hereof, which remains unpaid from time to time, exceed the Maximum Lawful Rate,
it particularly being the intention of the parties hereto to conform strictly to
the applicable usury laws of the State of Texas (or applicable United States law
to the extent that it permits the Lender to contract for, charge or receive a
greater amount of interest than under Texas law). Any interest payable hereunder
or under any other instrument relating to the indebtedness evidenced hereby that
is in excess of the Maximum Lawful Rate, shall, in the event of acceleration of
maturity, late payment, prepayment, or otherwise, be applied to a reduction of
the unpaid indebtedness hereunder and not to the payment of interest, or if such
excessive interest exceeds the unpaid balance of such unpaid indebtedness, such
excess shall be refunded to the Makers. To the extent not prohibited by
applicable law, determination of the Maximum Lawful Rate shall at all times be
made by amortizing, prorating, allocating and spreading in equal parts during
the full term of this loan, all interest at any time contracted for,



charged or received from the Makers in connection with this loan, so that the
actual rate of interest on account of such indebtedness is uniform throughout
the term thereof.

SUCCESSORS AND ASSIGNS:

     As used herein, the term "Lender" shall include the successors and assigns
of the Lender and any subsequent owner and holder of this Note, and the term
"Makers" shall include co-makers, endorsers, guarantors, sureties and their
respective successors and assigns.

DEFAULT AND COLLECTION:

     Subject to the express notice and cure rights described in this Note, it is
expressly provided that, upon default in the punctual payment of this Note, or
any part hereof, principal or interest, as the same shall become due and
payable, or if the Lender deems itself insecure, either because the prospect of
timely payment of this Note becomes impaired, or because the prospect of timely
performance of any of the Collateral Agreements becomes impaired, at the option
of the Lender, the entire indebtedness evidenced hereby shall be matured, and in
the event default is made in the prompt payment of this Note when due or
declared due, and the same is placed in the hands of an attorney for collection,
or suit is brought on the same, or the same is collected through probate,
bankruptcy or other judicial proceedings, then the Makers jointly and severally
agree and promise to pay all reasonable attorney's fees, court costs and
collection costs incurred by the Lender.

NOTICE AND CURE RIGHTS:

     In the event of any default under the Collateral Agreements or this Note,
or if the Lender deems itself insecure, the Makers shall be entitled to receive
written notice of any such default and a period of fifteen (15) days after such
notice is sent by the Lender within which to cure such default prior to the
Lender being entitled to exercise any remedy which may arise due to the
occurrence of such default, other than the right to withhold making further
advances of funds during the period any such default remains uncured. However,
nothing herein shall obligate the Lender to give the Makers more than one (1)
notice of default during any ninety (90) day period.

WAIVERS AND CONSENTS:

     Except for the express notice and cure provisions contained in this Note,
each of the Makers waives presentment for payment, notice of intent to
accelerate, notice of acceleration, protest and notice of protest, dishonor and
diligence in collecting and the bringing of suit against any other party, and
agrees to all renewals, extensions, partial payments, releases and substitutions
of security, in whole or in part, with or without notice, before or after
maturity. The Lender may remedy any default, without waiving the same, or may
waive any default without waiving any prior to subsequent default.



GOVERNING LAWS AND VENUE:

     This Note is governed by and is to be construed and enforced in accordance
with the laws of the State of Texas and of the United States. The Makers agree
and consent to the jurisdiction of the District Courts of Travis County, Texas,
and of the United States District Court for the Western District of Texas
(Austin Division) and acknowledge that such courts shall constitute proper and
convenient forums for the resolution of any actions among the Makers and the
Lender with respect to the subject matter hereof, and agree that such courts
shall be the exclusive forums for the resolution of any actions among the Makers
and the Lender with respect to the subject matter hereof.
