          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

                           AND RESULTS OF OPERATIONS


                        ANALYSIS OF STATEMENT OF INCOME

Effective May 1, 1995, the Company consummated its' acquisition of Texas Gulf
Coast Bancorp, Inc.  Such acquisition has been accounted for as a purchase.

The following analysis discusses material changes in the results of operations
for the second quarter of 1995 compared to the second quarter of 1994 and the
first six months of 1995 as compared to the first six months of 1994.  The
Company recorded earnings of $1,335,000 in the second quarter of 1995 and
$2,429,000 in the first six months of 1995 compared to $914,000 in the second
quarter of 1994 and $1,583,000 in the first six months of 1994.

NET INTEREST INCOME

Net interest income increased 64.3% in the second quarter of 1995 when compared
to the same period of 1994 and increased by 44.6% during the first six months of
1995 as compared to the first six months of 1994.  The net interest income of
Texas Gulf Coast accounted for 77.0% and 57% of the increases for the second
quarter and first six months, respectively.

Disregarding the acquisition of Texas Gulf Coast Bancorp, net interest income
increased 14.8% and 18.9% for the second quarter of 1995 and the first six
months of 1995, respectively.  The increase of $434,000 for the second quarter
of 1995 over the second quarter of 1994 resulted from an increase of $786,000
(19.0%) in interest income on earning assets offset by an increase of $352,000
(29.6%) in interest expense.  The increase of $1,071,000 for the first six
months of 1995 over the comparable period in 1994 resulted from an increase of
$1,521,000 (19.0%) in interest income offset by an increase of $450,000 (19.0%)
in interest expense.  Increases in earning assets and deposits were the primary
reasons for the increases in interest income and interest expense for both
periods in 1995 as compared to the comparable periods in 1994.

The Company's subsidiary banks (the "Subsidiary Banks") attempt to adjust the
rates paid or earned on interest bearing liabilities and interest earning assets
to maintain a consistent net interest margin to the extent possible.

PROVISION FOR POSSIBLE LOAN LOSSES

The provision for possible loan losses increased by $40,000 for the second
quarter of 1995 compared to the second quarter of 1994 and decreased by $10,000
for the first six months of 1995 as compared to the same period in 1994.  The
second quarter provision was completely attributable to the acquisition of Texas
Gulf Coast Bancorp.  The provision for possible loan losses for the first six
months of 1995 was offset by $40,000 in net losses charged to the allowance as
compared with net recoveries of $49,000 for the same period in 1994.  The ratio
of the allowance for possible loan losses to outstanding loans was 1.22% on June
30, 1995; as compared to 1.55% on June 30, 1994.  The allowance is $716,000 more
at June 30, 1995

                                       15
<PAGE>
 
than it was on the comparable date a year earlier, all of which is attributable
to the banks acquired May 1,1995. The improving quality of the Subsidiary Banks'
loan portfolios has enabled the Subsidiary Banks to decrease the provision for
possible loan losses for the six months ended June 30, 1995 despite increased
loan balances.

It is the policy of the Subsidiary Banks to maintain a level in the allowance
for possible loan losses that is adequate to cover the loan losses sustained
plus provide for any future possible losses on problem loans.  The adequacy of
the allowance is continually monitored and management considers the current
level to be appropriate based on an evaluation of the Subsidiary Banks' loan
portfolios.  The transactions in the allowance for possible loan losses were as
follows:

NON-PERFORMING ASSETS

All loans which cause management to have doubt as to the borrower's ability to
substantially comply with present loan repayment terms are included in the
schedule of non-performing loans.

Non-performing loans consist of loans on which interest is not being accrued and
loans which are 90 days or more past due as to principal and/or interest payment
and not yet in a non-accruing status.  The policy of the Subsidiary Banks is to
continue to accrue interest on loans which are 90 days or more past due if
periodic payments are being made on the loans.  If a loan is classified as past
due and payments then resume on the loan, it continues to be classified as past
due until all past due amounts are paid.

The following table discloses information regarding non-performing assets for
the indicated periods:

</TABLE>

The total of the various service charges and fees earned by the Company and
Subsidiary Banks for the second quarter and the first six months of 1995
increased by 47.8% and 22.6%, respectively, as compared to the comparable
periods of 1994.  Other operating income increased by $124,000 and $249,000 for
the second quarter and the first six months of 1995, respectively, as compared
to the same periods of 1994.

The increases in service charges and fees are completely attributable to the
acquisition of Texas Gulf Coast Bancorp.  Of the $124,000 increase in other
operating income during the second quarter of 1995, $90,000 is attributable to
the acquisition of Texas Gulf Coast Bancorp.  The $249,000 increase in other
operating income for the first six months of 1995 as compared to the same period
in 1994 also includes such $90,000 with the balance of the increase attributable
to the additional income generated by the Company's non-bank subsidiary in
increased data processing revenues.

The Company maintains a policy of constantly monitoring and evaluating service
charges and fees to ensure that the fees charged reflect the cost of service
provided and remain competitive with other financial institutions located in the
Subsidiary Banks' market area.

NON-INTEREST EXPENSE

Non-interest expenses increased 66.6% for the second quarter of 1995 over the

Salaries and benefits are the most significant operating expenses of the
Company.  Of the 76.8% and 38.2% increases for the second quarter and the first
six months of 1995, respectively, over the comparable periods of 1994, the
acquisition of Texas Gulf Coast Bancorp accounted for approximately 92% of each
of such increases.

Furniture, equipment and occupancy expense increased by 94.8% for the second
quarter of 1995 over the same quarter of 1994 and increased by 50.7% for the
first six months of 1995 as compared to the first six months of 1994.  The
occupancy expenses attributable to the acquisition of Texas Gulf Coast Bancorp
represent approximately 72% of the increases.  The increases of $355,000 and
$406,000 in other operating expenses for the second quarter and the first six
months of 1995 over the comparable periods of 1994, respectively, are completely
attributable to the acquisition of Texas Gulf Coast Bancorp.  The major
components of other operating expenses are legal and accounting fees, data
processing, supplies and advertising expenses.  Also included are expenses
related to real estate held for sale and other loan-related assets acquired
through foreclosure; although for 1995 these expenses represent a minimal amount
of the total.


                           ANALYSIS OF BALANCE SHEET

EARNING ASSETS

When comparing the total of earning assets at June 30, 1995, to the total at
December 31, 1994, earning assets increased 84.5%.  Included in the $194,474,000
increase are earning assets previously held by Texas Gulf Coast Bancorp totaling
$186,333,000.  The remaining increase is attributable to increases of $4,375,000
and $7,384,000 in federal funds sold and loans, respectively; partially offset
by decreases of $2,969,000 and $650,000 in investment securities and time
deposits in banks, respectively.

Included in the total of earning assets at June 30, 1995 are loans totaling
$1,657,000 which are on a non-accrual status.  This compares to non-accrual
loans totaling $1,209,000 and $1,215,000 at June 30, 1994 and December 31, 1994,
respectively.  The acquisition of Texas Gulf Coast Bancorp accounts for $501,000
in non-accrual loans at June 30,1995.

DEPOSITS

The most important funding source for earning asset growth is deposits.  Total
deposits increased by 82.5% from December 31, 1994 to June 30, 1995.  Included
in the $186,474,000 increase are deposits totaling $181,689,000 associated with
the acquisition of Texas Gulf Coast Bancorp.  In addition, the deposits of Gulf
Southwest's subsidiary bank increased by $4,785,000, or 2.1%, from the level at
December 31, 1994.  Non-interest bearing deposits represent 28.6% of total
deposits at June 30, 1995 as compared to 31.8% at December 31, 1994.

CAPITAL

Shareholders' equity totaled $45,649,000 at June 30, 1995 as compared to
$25,539,000 at December 31, 1994.  Included in the total at June 30, 1995 is
equity totaling approximately $18,212,000 attributable to the acquisition of
Texas Gulf Coast Bancorp.  The ratio of shareholders' equity to total assets was
9.8% on June 30, 1995, as compared to 10.1% on December 31, 1994 and 9.6% on
June 30, 1994.

Bank holding companies and their bank subsidiaries are required to maintain
certain capital ratios.  The Federal Reserve Board's guidelines classify capital
into two tiers, referred to as Tier 1 and Tier 2.  Tier 1 capital consists of
common and qualifying preferred shareholders' equity less goodwill.  Tier 2
capital consists of mandatory convertible debt, preferred stock not qualifying
as Tier 1, qualifying subordinated debt and the allowance for loan losses up to
1.25% of risk-weighted assets.  The minimum ratio for the sum of Tier 1 and Tier
2 to risk weighted assets is 8.0%, at least one-half of which should be in the
form of Tier 1 capital.  At June 30, 1995, core capital (Tier 1) and total
capital (Tier 1 and Tier 2) as a percentage of risk-weighted assets was 18.39%
and 19.55%, respectively.  The Subsidiary Banks at June 30, 1995 had core
capital of 18.67% and total capital of 19.83% as a percentage of risk weighted
assets.

In addition to the foregoing ratios, bank holding companies are required to
maintain a minimum ratio of core capital to total assets (hereinafter referred
to as the "Leverage Ratio") of at least 3.0%.  At June 30, 1995, the Company's
Leverage Ratio was 9.63%.  A similar leverage ratio applicable to the Subsidiary
Banks has been adopted by the FDIC.  At June 30, 1995, the Subsidiary Banks'
ratio was 9.79%.

LIQUIDITY AND CAPITAL COMMITMENTS

Liquidity is the ability of the Company and its Subsidiary Banks to meet their
short-term needs for cash arising from demands such as operating expenses,
withdrawal of deposits and demand for loans.  The liquidity of the Company is
primarily provided by dividends from the Subsidiary Banks and interest on time
deposits in financial institutions.

                                       20
<PAGE>
 
LIQUIDITY AND CAPITAL COMMITMENTS (CONTINUED)

The Subsidiary Banks' liquidity is primarily provided by maturing loans,
deposits, cash, short-term investments, time deposits in other banks, federal
funds sold and profits.  With bank regulators critically reviewing liquidity,
the Company has adopted a policy of maintaining a minimum liquidity level of 20%
as measured by the FDIC formula, at the Subsidiary Banks.  As of June 30, 1995,
the liquidity level of the Subsidiary Banks was 48.7%.

The Company believes that both it and the Subsidiary Banks have sufficient
capital and financial resources to meet its current and anticipated  capital
commitments.

Under restrictive loan covenants, Gulf Southwest Nevada Bancorp, Inc., a wholly
owned subsidiary of the Company may not pay dividends to the Company in excess
of its net earnings.

                                 (this "Note")


          FOR VALUE RECEIVED, ON OR BEFORE March 31, 1997 ("Stated Maturity"),
TEXAS GULF COAST BANCORP, INC. ("Borrower"), promises to pay to the order of
Bank at its office at 712 Main Street, Houston, Harris County, Texas, or at such
other location as Bank may designate, in immediately available funds and lawful
money of the United States of America, the sum of THREE MILLION FOUR HUNDRED
THOUSAND AND NO/100THS UNITED STATES DOLLARS (U.S. $3,400,000.00) or the
aggregate unpaid amount of all advances hereunder, whichever is lesser, plus
interest on the unpaid principal balance outstanding from time to time at a rate
per annum equal to the lesser of (i) the Prime Rate (as hereinafter defined)
from time to time in effect (the "Stated Rate") or (ii) the Highest Lawful Rate.
If the Stated Rate at any time exceeds the Highest Lawful Rate, the actual rate
of interest to accrue on the unpaid principal amount of this Note will be
limited to the Highest Lawful Rate, but any subsequent reductions in the Stated
Rate due to reductions in the Prime Rate will not reduce the interest rate
payable upon the unpaid principal amount of this Note below the Highest Lawful
Rate until the total amount of interest accrued on this Note equals the amount
of interest which would have accrued if the Stated Rate had at all times been in
effect.  "Prime Rate" means that rate as determined from time to time by Bank as
being its prime rate, and thereafter entered in the minutes of Bank's Loan and
Discount Committee.  Without notice to Borrower or any other Person, the Prime
Rate shall change automatically from time to time as and in the amount by which
said prime rate shall fluctuate with each such change to be effective as of the
date of each change in such prime rate.  THE PRIME RATE IS A REFERENCE RATE AND
DOES NOT NECESSARILY REPRESENT THE LOWEST OR BEST RATE.  BANK MAY MAKE LOANS AT
RATES OF INTEREST AT, ABOVE OR BELOW THE PRIME RATE.

          This Note is the Note described in Section 1.1 of the Credit Agreement
between Borrower and Texas Commerce Bank National Association ("Bank") dated as
of December 31, 1994 (as amended, restated and supplemented from time to time,
the "Agreement") and sometimes referred to therein as the Note.  Capitalized
terms used in this Note have the meanings used in the Agreement.

          The unpaid principal balance of this Note at any time shall be the
total amounts loaned or advanced by Bank or holder hereof, less the amount of
all payments or prepayments of principal made hereon by or for Borrower.  Absent
manifest error, the records of the Payee or any subsequent holder shall be
conclusive as to amounts owed, both principal and accrued interest, hereunder.
Subject to the terms and conditions of this Note and the Agreement and provided
that there is no default, Borrower may use all or any part of the credit
provided for herein at any time before March 31, 1995 (the "Advance Termination
Date") and may borrow and repay but not reborrow hereunder prior to the Advance
Termination Date and there is no limitation on the number of advances made
hereunder so long as the total amount advanced prior to the Advance Termination
Date does not exceed face amount of this Note.

          Accrued interest shall be due and payable quarterly, beginning March
31, 1995, and continuing on each June 30, September 30, December 31, and March
31 thereafter until the Stated Maturity when all accrued and unpaid interest
shall be finally due and payable.  Principal payments of $175,000.00 each (or
the remaining unpaid principal if less) shall be due and payable quarterly
beginning June 30, 1995 and continuing on each September 30, December 31, March
31 and June 30 thereafter until the Stated Maturity when all accrued and unpaid
interest shall be finally due and payable.  All unpaid principal and accrued and
unpaid interest shall be finally due and payable at the Stated Maturity.

          Interest shall be computed on the basis of the actual number of days
elapsed and a year comprised of 360 days, unless such calculation would result
in a usurious interest rate, in which case interest will be calculated on the
basis of a 365 or 366 day year, as applicable.

          All past-due principal and, to the extent permitted by applicable law,
interest on this Note, shall, at Bank's option, bear interest at the Highest
Lawful Rate, or if applicable law shall not

                                    Page 1
<PAGE>
 
provide for a maximum nonusurious rate of interest, at a rate per annum equal to
eighteen percent (18%).

          The unpaid principal balance of this Note at any time shall be the
total amounts advanced by Bank, less the amount of all payments of principal.
Absent manifest error, the records of Bank shall be conclusive as to amounts
owed.  Subject to the terms and conditions of the Agreement, Borrower may use
all or any part of the credit provided for herein at any time before the
Termination Date.

          Time is of the essence.  Borrower may at any time pay the full amount
or any part of this Note without the payment of any premium or fee.  Any
prepayment shall be in the amount of U.S. $10,000.00, or an integral multiple
thereof.  At Bank's sole option, all payments may be applied to accrued
interest, to principal, or to both.

          If any Event of Default occurs, then Bank may exercise any and all
rights and remedies under the Loan Documents, at law, in equity or otherwise.

          Each and all Obligors severally waive notice, demand, presentment for
payment, notice of nonpayment, notice of intent to accelerate, notice of
acceleration, protest, notice of protest, and the filing of suit and diligence
in collecting this Note and all other demands and notices, and consent and agree
that their liabilities and obligations shall not be released or discharged by
any or all of the following, whether with or without notice to them or any of
them, and whether before or after the stated maturity hereof:  (i) extensions of
the time of payment; (ii) renewals; (iii) acceptances of partial payments; (iv)
releases or substitutions of any collateral or any obligor; and (v) failure, if
any, to perfect or maintain perfection of any security interest in any
collateral.  Each Obligor agrees that acceptance of any partial payment shall
not constitute a waiver.

          Bank and any subsequent owner or holder hereof reserves the right, in
its sole discretion, without notice to Borrower, to sell participations or
assign its interest or both, in all or any part of this Note.  For purposes of
this Note, any assignee or subsequent holder of this Note will be considered the
"Bank," and each successor to Borrower will be considered the "Borrower."

IN WITNESS WHEREOF, Borrower has executed this Note effective as of the
Effective Date.

1.   THE LOANS.

ADVANCE CREDIT NOTE 1.1 Subject to the terms and conditions hereof, Bank agrees
to make loans ("Loan" or "Loans") to Borrower from time to time before March 31,

"Renewed Note"); and (2) redeem preferred stock issued by Borrower.  Chapter 15
of the Texas Credit Code will not apply to this Agreement, the Note or any Loan.
The Loans will be evidenced by, and will bear interest and be payable as
provided in, the promissory note of Borrower dated the Effective Date and
maturing March 31, 1997 (together with any and all renewals, modifications and
replacements thereof and substitutions therefor, the "Note").

arising out of or relating to the Loans or any Loan Document, but not limited to
any claim based on or arising from an alleged tort or an alleged breach of any

party to the Loan or Loan Documents (either before or after the commencement of
judicial proceedings), be settled by mandatory and binding arbitration in
accordance with the Commercial Arbitration Rules of

<PAGE>
 
Credit Agreement        December 31, 1994        Texas Gulf Coast Bancorp, Inc.


the American Arbitration Association (the "AAA Rules") and pursuant to Title 9
of the United States Code, or if Title 9 does not apply, the Texas General
Arbitration Act.  In any arbitration proceeding (i) all statutes of limitations
which would otherwise be applicable shall apply, and (ii) the proceeding shall
be conducted in the city in which the office of Bank originating the Loans is
located, by a single arbitrator if the amount in controversy is $1 million or
less, or by a panel of three arbitrators if the amount in controversy (including
but not limited to all charges, principal, interest fees and expenses) is over
$1 million.  Arbitrators are empowered to resolve any controversy by summary
rulings substantially similar to summary judgments and motions to dismiss.
Arbitrators may order discovery conducted in accordance with the Federal Rules
of Civil Procedures.  All arbitrators will be selected by the process of
appointment from a panel, pursuant to the AAA Rules.  Any award rendered in the
arbitration proceeding will be final and binding, and judgment upon any such
award may be entered in any court having jurisdiction.

(b) If any party to the Loan or Loan Documents files a proceeding in any court
to resolve any controversy or claim, such action will not constitute a waiver of
the right of such party or a bar to the right of any other party to seek
arbitration under the provisions of this Section or that of any other claim or
controversy, and the court shall, upon motion of any party to the proceeding,
direct that the controversy or claim be arbitrated in accordance with this
Section.

(c) No provision of, or the exercise of any rights under, this Section shall
limit or impair the right of any party to the Loan Documents before, during or
after any arbitration proceeding to: (i) exercise self-help remedies including
but not limited to setoff or repossession; (ii) foreclose any Lien on or
security interest in any Collateral; or (iii) obtain relief from a court of
competent jurisdiction to prevent the dissipation, damage, destruction,
transfer, hypothecation, pledging or concealment of assets or Collateral
including, but not limited to attachments, garnishments, sequestrations,
appointments of receivers, injunctions or other relief to preserve the status
quo.

(d) To the maximum extent permitted by applicable law and the AAA Rules, neither
Bank or any Obligor or any Affiliate, officer, director, employee, attorney, or
agent of either shall have any liability with respect to, and Bank and each
Obligor waives, releases, and agrees not to sue any of them upon, any claim for
any special, indirect, incidental and consequential damages suffered or incurred
by such Person in connection with arising out of, or in any way related to, this
Agreement or any of the other Loan Documents.  Each of Bank and each Obligor
waives, releases, and agrees not to sue each other or any of their Affiliates,
officers, directors, employees, attorneys, or agents for punitive damages in
respect of any claim in connection with, arising out of, or in any way related
to, this Agreement or any of the other Loan Documents, or any of the
transactions contemplated by this Agreement or any of the other Loan Documents.
Nothing contained herein, however, shall be construed as a waiver of any
Obligor's or the Bank's right to compel arbitration of disputes pursuant to
subparagraphs (a) and (b), above.

(e) Nothing herein shall be considered a waiver of the right or protections
afforded Bank by 12 U.S.C. 91, Texas Banking Code Art. 342.609 or any similar
statute.

(f) Each party agrees that any other party may proceed against any other liable
Person, jointly or severally, or against one or more of them, less than all,
without impairing rights against any other liable Persons.  A party shall not be
required to join the principal Obligor or any other liable Persons (e.g.,
sureties or guarantors) in any proceeding against any Person.  A party may
release or settle with one or more liable Persons as the party deems fit without
releasing or impairing right to proceed against any Persons not so released.

SURVIVAL PARTIES BOUND; TERM OF AGREEMENT 7.4  All representations, warranties,
covenants and agreements made by or on behalf of Borrower in connection with the
Loan Documents will survive the execution and delivery of the Loan Documents,
will not be affected by any investigation made by any Person, and will bind
Borrower and the successors, trustees, receivers and assigns of Borrower and
will benefit the successors and assigns of the Bank provided that Bank's
agreement to make Loans to Borrower will not inure to the benefit of any
successor or assign of Borrower.  Except as otherwise provided herein, the term
of this Agreement will be until the later of the final maturity of the Note and
the full and final payment of all amounts due under the Loan Documents.

Credit Agreement        December 31, 1994        Texas Gulf Coast Bancorp, Inc.


DOCUMENTARY MATTERS 7.5  This Agreement may be executed in several identical
counterparts, on separate counterparts; each counterpart will constitute an
original instrument, and all separate counterparts will constitute but one and
the same instrument.  The headings and captions in the Loan Documents have been
included solely for convenience and should not be considered in construing the
Loan Documents.  If any provision of any Loan Document is invalid, illegal or
unenforceable in any respect under any applicable law, the remaining provisions
will remain effective.  The Loans and all other obligations and indebtedness of
Borrower to Bank are entitled to the benefit of the Loan Documents.

EXPENSES 7.6  Any provision to the contrary notwithstanding, and whether or not
the transaction contemplated by this Agreement are consummated, Borrower agrees
to pay on demand all out-of-pocket expenses (including, without limitation, the
fee and expenses of counsel for Bank) in connection with the negotiation,
preparation, execution, filing, recording, modification, supplementing and
waiver of the Loan Documents and the making, servicing and collection of the
Loans.  Borrower agrees to pay Bank's standard Documentation Preparation and
Processing Fee for preparation, negotiation and handling of this Agreement.  The
obligations of the Borrower under this and the following section will survive
the termination of this Agreement.

INDEMNIFICATION 7.7  THE BORROWER AGREES TO INDEMNIFY, DEFEND AND HOLD BANK
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 BANK MAY BECOME
SUBJECT ARISING OUT OF OR BASED UPON THE LOAN DOCUMENTS, OR ANY LOAN, INCLUDING
THAT RESULTING FROM BANK'S OWN NEGLIGENCE, EXCEPT AND TO THE EXTENT CAUSED BY
BANK'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

NATURE OF OBLIGATIONS 7.8  If more than one Borrower executes this Agreement,
all of the representations, warranties, covenants and agreements of Borrower
shall be joint and several obligations of all Borrowers.

USURY NOT INTENDED 7.9  Borrower and Bank intend to conform strictly to
applicable usury laws.  Therefore, the total amount of interest (as defined
under applicable law) contracted for, charged or collected under this Agreement
or any other Loan Document will never exceed the Highest Lawful Rate.  If Bank
contracts for, charges or receives any excess interest, it will be deemed a
mistake.  Bank will automatically reform the Loan Document or change to conform
to applicable law, and if excess interest has been received, Bank will either
refund the excess to Borrower or credit the excess on any unpaid principal
amount of the Note or any other Loan Document.  All amounts constituting
interest will be spread throughout the full term of the Loan Document or
applicable Note in determining whether interest exceeds lawful amounts.

NO COURSE OR DEALING 7.10  NO COURSE OF DEALING BY BORROWER WITH BANK, NO COURSE
OF PERFORMANCE AND NO TRADE PRACTICES OR OTHER EXTRINSIC EVIDENCE OF ANY NATURE
MAY BE USED TO CONTRADICT, VARY, SUPPLEMENT OR MODIFY ANY TERM OF THIS
AGREEMENT.

     Agreement and the right, title, security interest and other interests
     created or evidenced hereby, and, subject to the restrictions in Section
     III of this Security Agreement, all expenses so incurred of every kind and

     Rate and shall be secured hereby and by each other agreement securing the
     secured indebtedness.  The party incurring such expenses shall be
     subrogated to all rights of the person receiving such payment.

       (e) Debtor will, on request of Secured Party, (i) promptly correct any
     defect, error or omission which may be discovered in the contents of this
     Security Agreement or in any other instrument executed in connection
     herewith or in the execution or acknowledgement thereof; (ii) execute,
     acknowledge, deliver and record or file such further instruments (including
     without limitation further security agreements, financing statements and

     desirable or proper to carry out more effectively the purposes of this
     Security Agreement and such other instruments and to subject to the
     security interests hereof and thereof any property intended by the terms
     hereof and thereof to be covered hereby and thereby, including
     specifically, but without limitation, any renewals, additions,
     substitutions,

     replacements or appurtenances to the then Collateral and (iii) execute,
     acknowledge, deliver, procure and record or file any document or instrument
     (including specifically any financing statement) deemed advisable by
     Secured Party to protect the security interests hereunder against the

     connected with any of the foregoing.

       (f) Notwithstanding the security interest in proceeds granted herein,
     Debtor will not sell, exchange, lend, assign, transfer or otherwise dispose
     of all or any part of the Collateral or any interest therein, or permit any
     of the foregoing, without the prior written consent of Secured Party.

       (g) Subject to the restrictions in Section III of this Security
     Agreement, and to the extent not prohibited by law, Debtor will pay, or
     reimburse Secured Party for, all costs and expenses, of every character,
     incurred or expended from time to time (including, but not limited to, the
     fees and expenses of counsel for Secured Party) in connection with the
     negotiation, preparation, execution, filing, recording, refiling and re-
     recording of this Agreement and all related financing statements and the
     making, servicing and collection of the indebtedness secured hereby; any
     and all stamp, mortgage and recording taxes; and all costs of negotiation,
     preparation, execution and delivery of any and all amendments,
     modifications, supplements, consents, waivers or other documents or
     writings relating to the transactions contemplated by this Agreement.
     Subject to the restrictions in Section III of this Security Agreement,
     Debtor will reimburse Secured Party for all amounts expended by Secured
     Party to satisfy any obligation of Debtor under this Agreement or to
     protect the Collateral.  In addition, whether or not a default shall have
     occurred, subject to the restrictions in Section III of this Security
     Agreement, Debtor will pay, or reimburse Secured Party for, all costs and
     expenses, of every character incurred or expended from time to time in

     from the date of expenditure by Secured Party until paid at the Past Due
     Rate.

       (h) Debtor will not change its address, name, identity or structure

     (30) days prior to the effective date of such change.

     separate and distinct from other property of Debtor and shall keep accurate
     and complete records of the Collateral and its proceeds.

       (j) Debtor shall furnish Secured Party all such information as Secured
     Party may request with respect to the Collateral.

       (k) If Secured Party should at any time be of the opinion that the
     Collateral is not sufficient or has declined or may decline in value, or
     should a decline in the value of the Collateral cause any indebtedness
     secured hereby to be in violation of 12 USC 84 or any regulation
     implementing such law, or should Secured Party deem payment of Debtor's
     obligations to Secured Party to be insecure, then Secured Party may call
     for additional Collateral satisfactory to Secured Party, and Debtor
     promises to furnish such additional security forthwith, but in no event
     later than five days from the date Secured Party requests such additional
     Collateral.  The call for additional security may be oral or by telegram or
     by United States Postal Service addressed to the address of Debtor shown at
     the beginning of this Security Agreement.

 5.2   Subject to the restrictions in Section III of this Security Agreement,
     Debtor agrees that, if Debtor fails to perform any act or to take any
     action which hereunder Debtor is required to perform or take, or to pay any
     money which hereunder Debtor is required to pay, Secured Party, in Debtor's
     name or in its own name, may but shall not be obligated to perform or cause
     to be performed such act or take such action or pay such money, and any
     expenses so incurred by Secured Party, and any money so paid by Secured
     Party, shall be a demand obligation owing by Debtor to Secured Party and
     Secured Party, upon making such payment, shall be subrogated to all of the
     rights of the person, corporation or body politic receiving such payment.
     Any amounts due and owing by Debtor to Secured Party pursuant to this
     Security Agreement shall bear interest from the date such amount becomes
     due until paid at the Past Due Rate and shall be a part of the secured
     indebtedness and shall be secured by this Security Agreement and by any
     other instrument securing the secured indebtedness.

SECTION VI.  VOTING RIGHTS AND DIVIDENDS.

  Unless and until an Event of Default, as hereinafter defined, shall have
occurred, Debtor shall be entitled to exercise all voting and consensual powers
and rights pertaining to the Collateral or any part thereof for all purposes not
inconsistent with the terms of this Security Agreement and shall be entitled to
receive and retain all dividends (other than stock or liquidating dividends) on
the Collateral or any part thereof, provided that all dividends in stock or
property representing stock, and all subscription, warrants or any other rights
or options issued in connection with the Collateral, and all liquidating
dividends or distributions or return of capital upon or in respect of the

     Agreement or made or furnished to Secured Party by or on behalf of Debtor
     in connection with this Security Agreement or to induce Secured Party to

     when made or furnished; or

       (e) Debtor's death, dissolution, termination of existence, insolvency or
     business failure; the failure of Debtor or of any guarantor or surety for

       (h) any adverse material change shall occur in the assets, liabilities,
     financial condition, business operations, affairs or circumstances of
     Debtor.

SECTION VIII.  REMEDIES IN EVENT OF DEFAULT.

 8.1   Upon the occurrence of an Event of Default, or if Secured Party shall
     deem payment of Debtor's obligations to Secured Party to be insecure, and
     at any time thereafter, Secured Party shall have the option of declaring,
     without notice to any person, all indebtedness secured hereby; principal
     and accrued interest, to be immediately due and payable.

 8.2   Upon the occurrence of an Event of Default, or if Secured Party shall
     deem payment of Debtor's obligations to Secured Party to be insure, and at
     any time thereafter, Secured Party may without notice, except as
     thereinafter provided, sell the Collateral or any part thereof at public or
     private sale or at any broker's board or on any securities exchange for
     cash, upon credit, or for future delivery, and at such price or prices as
     Secured Party may deem best, and Secured Party may be the purchaser of any
     and all of the Collateral so sold and may apply upon the purchase price
     therefor any indebtedness secured hereby or any part thereof, and
     thereafter hold the same absolutely free from any right or claim of
     whatsoever kind.  Secured Party is authorized at any such sale, if Secured
     Party deems it advisable so to do, to restrict the prospective bidders or
     purchasers to persons who will represent and agree that they are purchasing
     the Collateral for their own account for investment and not with a view to
     the distribution or resale of any of the Collateral.  Upon any such sale,
     Secured Party shall have the right to deliver, assign and transfer to the
     purchaser thereof the Collateral so sold.  Each purchaser at any such sale
     shall hold the property sold absolutely free from any claim or right of
     whatsoever kind, including any equity or right of redemption, stay or
     appraisal which Debtor has or may have under any rule of law or statute now
     existing or hereafter adopted.  Secured Party shall give Debtor ten (10)
     days written notice mailed to Debtor at the address set forth herein (which
     shall satisfy any requirement of notice or reasonable notice in any
     applicable statute) of Secured Party's intention to make any such public or
     private sale.  Such notice, in case of public sale, shall state the time
     and place fixed for such sale, and in case of sale at broker's board or on
     a securities exchange, shall state the board or exchange at which such sale
     is to be made and the day on which the Collateral or that portion thereof
     so being sold will first be offered for sale at such board or exchange.
     Any such public sale shall be held at such time or times within the
     ordinary business hours and at such place or places as Secured Party may
     fix in the notice of such sale.  At any sale, the Collateral may be sold in
     one lot as an entirety or in separate parcels as Secured Party may
     determine.

       Secured Party shall not be obligated to make any sale pursuant to any
     such notice.  Secured Party may, without notice or publication, adjourn any
     public or private sale or cause the same to be adjourned from time to time
     by announcement at any time and place fixed for the sale, and such sale may
     be made at any time or place to which the same may be so adjourned.  In
     case of any sale of all or any part of the Collateral on credit or for
     future delivery, the Collateral so sold may be retained by Secured Party
     until the selling price is paid by the purchaser thereof, but Secured Party
     shall incur no liability in case of the failure of such purchaser to take
     up and pay for the Collateral so sold, and in case of any such failure,
     such Collateral may again be sold upon like notice.  Each and every method
     of disposition described in this Section shall constitute disposition in a
     commercially reasonable manner.  Debtor, subject to the restrictions in
     Section III of this Security Agreement, shall remain liable for any
     deficiency.

 8.3   Upon the occurrence of an Event of Default, or if Secured Party shall
     deem payment of Debtor's obligations to Secured Party to be insecure, and
     at any time thereafter, Secured Party shall have all the rights of a
     secured party after default under the Uniform Commercial Code of Texas, and
     in conjunction with, in addition to or in substitution for those rights and
     remedies and the rights and remedies provided for herein:

       (a) Written notice mailed to Debtor as provided herein ten (10) days
     prior to the date of public sale of the Collateral or prior to the date
     after which private sale of the Collateral will be made shall constitute
     reasonable notice; and

       (b) It shall not be necessary that the Collateral or any part thereof be
     present at the location of such sale; and

       (c) Prior to application of proceeds of disposition of the Collateral to
     the secured indebtedness, such proceeds shall be applied, subject to the
     restrictions in Section III of this Security Agreement, to the reasonable
     expenses of retaking, holding, preparing for sale or lease, selling,
     leasing and the like and the attorneys' fees and legal expenses incurred by
     Secured Party, Debtor, subject to the restrictions in Section III of this
     Security Agreement, to remain liable for any deficiency; and

       (d) The sale by Secured Party of less than the whole of the Collateral
     shall not exhaust the rights of Secured Party hereunder, and Secured Party
     is specifically empowered to make successive sale or sales hereunder until
     the whole of the Collateral shall be sold; and, if the proceeds of such
     sale of less than the whole of the Collateral shall be less than the
     aggregate of the indebtedness secured hereby, this Security Agreement and
     the security interest created hereby shall remain in full force and effect
     as to the unsold portion of the Collateral just as though no sale had been
     made; and

       (e) In the event any sale hereunder is not completed or is defective in
     the opinion of Secured Party, such sale shall not exhaust the rights of
     Secured Party hereunder and Secured Party shall have the right to cause a
     subsequent sale or sales to be made hereunder; and

       (f) Any and all statements of fact or other recitals made in any bill of
     sale or assignment or other instrument evidencing any foreclosure sale
     hereunder as to nonpayment of the indebtedness or as to the occurrence of
     any default, or as to Secured Party having declared all of such
     indebtedness to be due and payable, or as to notice of time, place and
     terms of sale and the properties to be sold having been duly given, as to
     any other act or thing having been duly done by Secured Party, shall be
     taken as prima facie evidence of the truth of the facts so stated and
     recited; and

                                  Page 4 of 7
<PAGE>
 
       (g) Secured Party may appoint or delegate any one or more persons as
     agent to perform any act or acts necessary or incident to any sale held by
     Secured Party, including the sending of notices and the conduct of sale but
     in the name and on behalf of Secured Party.

 8.4   All remedies herein expressly provided for are cumulative of any and all
     other remedies existing at law or in equity and are cumulative of any and
     all other remedies provided for in any other instrument securing the
     payment of the secured indebtedness, or any part thereof, or otherwise
     benefiting Secured Party, and the resort to any remedy provided for
     hereunder or under any such other instrument or provided for by law shall
     not prevent the concurrent or subsequent employment of any other
     appropriate remedy or remedies.

 8.5   Secured Party may resort to any security given by this Security Agreement
     or to any other security now existing or hereafter given to secure the
     payment of the secured indebtedness, in whole or in part, and in such
     portions and in such order as may seem best to Secured Party in its sole
     and uncontrolled discretion, and any such action shall not be considered as
     a waiver of any of the rights, benefits or security interests evidenced by
     this Security Agreement.

 8.6   Secured Party may at any time cause any or all of the Collateral to be
     transferred into its name or into the name or names of any nominee or
     nominees of Secured Party.

 8.7   To the full extent Debtor may do so, Debtor agrees that Debtor will not
     at any time insist upon, plead, claim or take the benefit or advantage of
     any law now or hereafter in force provided for any appraisement, valuation,
     stay, extension or redemption, and Debtor, for Debtor, Debtor's heirs,
     devisees, personal representatives, receivers, trustees, successors and
     assigns, and for any and all persons ever claim any interest in the
     Collateral, to the extent permitted by law, hereby waives and releases all
     rights of redemption, valuation, appraisement, stay of execution, notice of
     intention to mature or declare due the whole of the secured indebtedness,
     notice of election to mature or declare due the whole of the secure
     indebtedness, and all rights to a marshaling of the assets of Debtor,
     including the Collateral, or to a sale in inverse order of alienation in
     the event of foreclosure of the security interest hereby created.  If this
     Security Agreement is governed by any of the Chapters, nothing herein shall
     be construed to waive any right accruing to Debtor under such Chapter.

SECTION IX.  ADDITIONAL AGREEMENTS.

 9.1   If all of the secured indebtedness be paid as the same becomes due and
     payable, and if all of the covenants, warranties, undertakings and
     agreements made in this Security Agreement are kept and performed, then and
     in that event only, all rights under this Security Agreement shall
     terminate and the Collateral shall become wholly clear of the security
     interest evidenced hereby, and such security interest shall be released by
     Secured Party in due form and, subject to the restrictions in Section III
     of this Security Agreement, at Debtor's cost.

 9.2   Secured Party may waive any default without waiving any other prior or
     subsequent default.  Secured Party may remedy any default without waiving
     the default remedied.  The failure by Secured Party to exercise any right,
     power or remedy upon any default shall not be construed as a waiver of such
     default or as a waiver of the right to exercise any such right, power or
     remedy at a later date.  No single or partial exercise by Secured Party of
     any right, power or remedy hereunder shall exhaust the same or shall
     preclude any other or further exercise thereof, and every such right, power
     or remedy hereunder may be exercised at any time and from time to time.  No
     modification or waiver of any provision hereof nor consent to any departure
     by Debtor therefrom shall in any event be effective unless the same shall
     be in writing and signed by Secured Party and then such waiver or consent
     shall be effective only in the specific instances, for the purpose of which
     given and to the extent therein specified.  No notice to nor demand on
     Debtor in any case shall of itself entitle Debtor to any other or further
     notice or demand in similar or other circumstances.  Acceptance by Secured
     Party of any payment in an amount less than the amount then due on any
     secured indebtedness shall be deemed an acceptance on account only and
     shall not in any way affect the existence of a default hereunder.

 9.3   Secured Party may at any time and from time to time in writing (a) waive
     compliance by Debtor with any covenant herein made by Debtor to the extent
     and the manner specified in such writing; (b) consent to Debtor's doing any
     act which hereunder Debtor is prohibited from doing, or consent to Debtor's
     failing to do any act which hereunder Debtor is required to do, to the
     extent and in the manner specified in such writing; (c) release any part of
     the Collateral, or any interest therein, from the security interest of this
     Security Agreement; or (d) release any party liable, either directly or
     indirectly, for the secured indebtedness or for any covenant herein or in
     any other instrument now or hereafter securing the payment of the secured
     indebtedness.  No such act shall in any way impair the rights of Secured
     Party hereunder, or impair or release the liability of any party except to
     the extent specifically agreed to by Secured Party in such writing.

 9.4   The security interest and other rights of Secured Party hereunder shall
     not be impaired by any indulgence, moratorium or release granted by Secured
     Party, including but not limited to (a) any renewal, extension or
     modification which Secured Party may grant with respect to any secured
     indebtedness; (b) any surrender, compromise, release, renewal, extension,
     exchange or substitution which Secured Party may grant in respect of any
     item of the Collateral, or any part thereof or any interest therein; or (c)
     any release or indulgence granted to any indorser, guarantor or surety of
     any secured indebtedness.

 9.5   A carbon, photographic or other reproduction of this Security Agreement
     or of any financing statement relating to this Security Agreement shall be
     sufficient as a financing statement.

 9.6   Debtor will cause all financing statements and confirmation statements
     relating hereto to be recorded, filed, re-recorded and refiled in such
     manner and in such places as Secured Party may reasonably request, and,
     subject to the restrictions in Section III of this Security Agreement, will
     pay all such recording, filing, re-recording and refiling taxes, fees and
     other charges.

 9.7   In the event the ownership of the Collateral or any part thereof becomes
     vested in a person other than Debtor, Secured Party may, without notice to
     Debtor, deal with such person with reference to this Security Agreement and
     to the indebtedness secured hereby in the same manner as with Debtor,
     without in any way vitiating or discharging Debtor's liability hereunder or
     for the payment of the indebtedness secured hereby.  No sale of the
     Collateral, no forbearance on the part of Secured Party and no extension of
     the time for the payment of the indebtedness secured hereby given by
     Secured Party shall operate to release, discharge, modify, change or
     affect, in whole or in part, the liability of Debtor hereunder or the
     liability of any other person hereunder or for the payment of the
     indebtedness secured hereby, except as agreed in writing by Secured Party.

 9.8   If any part of the secured indebtedness cannot be lawfully secured by
     this Security Agreement, or if any part of the Collateral cannot be
     lawfully subject to the security interest hereof to the full extent of such
     indebtedness, then all payments

                                  Page 5 of 7
<PAGE>
 
     made shall be applied on said indebtedness first if discharge of that
     portion thereof which is not secured by this Security Agreement.

 9.9   Secured Party may assign this Security Agreement so that the assignee
     shall be entitled to the rights and remedies of Secured Party hereunder.

 9.10    Any notice, request, demand or other communication required or
     permitted hereunder, or under any note, guaranty, loan agreement or other
     instrument securing the payment of the secured indebtedness (unless
     otherwise expressly provided therein) shall be given in writing by
     delivering same in person to the intended addressee, or by United States
     Postal Service, postage prepaid, registered or certified mail, return
     receipt requested or by prepaid telegram (provided that such telegram is
     confirmed by mail in the manner previously described), sent to the intended
     addressee at the address shown in this Agreement, or to such different
     address as the addressee shall have designated by written notice sent in
     accordance herewith and actually received by the other party at least ten
     (10) days in advance of the date upon which such change of address shall be
     effective.

 9.11    This Security Agreement shall be binding upon Debtor, and the heirs,
     devisees, personal representatives, receivers, trustees, successors and
     assigns of Debtor, including all successors in interest of Debtor in and to
     all or any part of the Collateral, and shall inure to the benefit of
     Secured Party and the successors and assigns of Secured Party.

 9.12    Secured Party in its discretion may, whether or not any of the
     indebtedness secured hereby be due, in its name or in the name of Debtor or
     otherwise, demand, sue for, collect or receive any money or other property
     at any time payable or receivable on account of or in exchange for, or make
     any compromise or settlement deemed desirable with respect to, any of the
     Collateral, but Secured Party shall be under no obligation so to do.

 9.13    Whenever possible, each provision of this Security Agreement shall be
     interpreted in such manner as to be effective and valid under applicable
     law.  A determination that any provision of this Security Agreement is
     unenforceable or invalid shall not affect the enforceability or validity of
     any other provision, and any determination that the application of any
     provision of this Security Agreement to any person or circumstance is
     illegal or unenforceable shall not affect the enforceability or validity of
     such provision as it may apply to any other persons or circumstances.

 9.14    Secured Party may, by any employee or employees it designates, execute,
     sign, indorse, transfer or deliver in the name of Debtor, notes, checks,
     drafts or other instruments for the payment of money and receipts or any
     other document necessary to evidence, perfect and realize upon the security
     interests and obligations of this Security Agreement.

 9.15    Secured Party's duty with reference to the Collateral shall be solely
     to use reasonable care in the custody and preservation of the Collateral in
     Secured Party's possession.  Secured Party shall not be responsible in any
     way for any depreciation in the value of the Collateral, nor shall any duty
     or responsibility whatsoever rest upon Secured Party to take necessary
     steps to preserve rights against prior parties or to enforce collection of
     the Collateral by legal proceedings or otherwise, the sole duty of the
     Secured Party, its successors and assigns, being to receive collections,
     remittances and payments on such Collateral as and when made.  In the event
     Debtor instructs Secured Party, in writing or orally, to deliver any or all
     of the Collateral to a broker or other third person, and Secured Party
     agrees to do so, the following conditions shall be conclusively deemed to
     be a part of secured party's agreement, whether or not they are
     specifically mentioned to Debtor at the time of such agreement.  Secured
     Party shall assume no responsibility for checking the genuineness or
     authenticity of any person purporting to be a messenger, employee or
     representative of the broker or other third person to whom Debtor has
     directed Secured Party to deliver the Collateral, or the genuineness or
     authenticity of any document or instructions delivered by any such person.
     Debtor will be considered, by requesting any such delivery, to have assumed
     all risk of loss as to the Collateral.  Secured Party's sole responsibility
     will be to deliver the Collateral to the person purporting to be the broker
     or other third person described by Debtor, or a messenger, employee or
     representative thereof.  Secured Party and Debtor hereby expressly agree
     that the foregoing actions by Secured Party shall constitute reasonable
     care.

 9.16    Notwithstanding anything to the contrary contained herein, if any
     secured indebtedness shall be indebtedness resulting from an extension of
     credit to a consumer (as such terms are defined or described in 12 C.F.R.
     227, Regulation AA of the Federal Reserve Board) hereinafter referred to as
     "consumer credit obligation" then the collateral securing any such consumer
     credit obligation shall not extend to any nonpossessory security interest
     in household goods which is not a purchase money security interest (as
     defined in said Regulation AA), and no waiver of any notice herein shall be
     construed under any circumstances to extend to any waiver of notice which
     is prohibited by Regulation AA.

 9.17    The term "Debtor" as used in this Security Agreement shall be construed
     as singular or plural to correspond with the number of persons executing
     this Security Agreement as Debtor.  The pronouns used in this Security
     Agreement are in the masculine gender but shall be construed as feminine or
     neuter as occasion may require.  "Secured Party" and "Debtor" as used in
     this Security Agreement include the heirs, executors or administrators,
     successors, representatives, receivers, trustees and assigns of those
     parties.

 9.18    If more than one person executes this Security Agreement as Debtor,
     their obligations under this Security Agreement shall be joint and several.

 9.19    The section headings appearing in this Security Agreement have been
     inserted for convenience only and shall be given no substantive meaning or
     significance whatever in construing the terms and provision of this
     Security Agreement.  Terms used in this Security Agreement which are
     defined in the Texas Uniform Commercial Code are used with the meanings as
     therein defined.

 9.20    This Security Agreement shall be governed by and construed in
     accordance with the laws of the state of Texas and the United States of
     America.
