                     NOTES TO COMBINED FINANCIAL STATEMENTS


1.       BASIS OF PRESENTATION

                 In the opinion of Casa Ole Restaurants, Inc. (the "Company"),
         the accompanying combined financial statements contain all adjustments
         (consisting only of normal recurring accruals and adjustments)
         necessary for a fair presentation of the combined financial position
         as of July 12, 1996, and the combined statements of income and cash
         flows for the 28-week and 12-week periods ended July 12, 1996 and July
         14, 1995.  The combined statements of income for the 28-week and
         12-week periods ended July 12, 1996, are not necessarily indicative of
         the results to be expected for the full year.

2.       ACCOUNTING POLICIES

                 During the interim periods the Company follows the accounting
         policies set forth in its combined financial statements in its
         Prospectus dated April 25, 1996.  Reference should be made to such
         financial statements for information on such accounting policies and
         further financial details.

3.       PRO FORMA DATA

                 The pro forma income statement data reflects adjustments to
         compensation and related party expense arrangements, and reflects an
         adjustment to the provision for income taxes to reflect a 37%
         effective tax rate, as if the Company had been taxed as a C
         corporation prior to the effective date of the Company's initial
         public offering.

                 Pro forma weighted average shares for the 28-week and 12-week
         periods ended July 14, 1995, and the 16- week period ended April 19,
         1996, represent the number of shares (2,732,705) issued pursuant to
         the contribution agreement for the predecessor companies (effective
         April 24, 1996) and 60,411 shares assumed to be issued to fund certain
         S corporation distributions.  Pro forma weighted average shares for
         the 12-week period ended July 12, 1996, represent the number of shares
         (2,732,705) issued pursuant to the contribution agreement for the
         predecessor companies, reduced by redeemed shares and increased by
         shares issued in the Company's initial public offering, along with
         common equivalent shares (stock options and warrants) determined using
         the treasury stock method.

4.       INITIAL PUBLIC OFFERING

                 The Company announced its initial public offering of 2,000,000
         shares of Common Stock at a price of $11.00 per share on April 25,
         1996.  On May 1, 1996, the Company redeemed 1,135,000 shares of Common
         Stock for $10.00 per share from a principal of the Company.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
         FINANCIAL CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

         Revenues.  The Company's revenues for the second quarter of fiscal
1996 of $4.2 million were up 4.5% over revenues of $4.1 million for the same
quarter a year ago.  Restaurant sales for the second quarter of 1996 were up
$139,000 over the same quarter a year ago, to $4.0 million.  Sales at
restaurants operating in both fiscal quarters ("same-stores") were up 6.7% over
last year's same quarter.  This increase was principally the result of
increased volume for the operating restaurants.

         Revenues for the 28 weeks ended July 12, 1996, increased $185,000, or
2.0%, to $9.6 million from $9.4 for the same period a year ago.  Of the
increase, $108,000 was in restaurant sales.  Same-store sales for the 28 weeks
ended July 12, 1996 were up 5.2% over the same period last year.

         During the first and second quarters of 1995, the Company operated two
restaurants that did not conform to the Company's current operating model.  One
of those restaurants was closed during the first quarter of 1995, and the other
restaurant was closed at the end of the second quarter of 1995.  During the
first and second quarters of 1995, sales of approximately $294,000 and
$110,000, respectively, were generated by these restaurants.

         Costs and Expenses.  Cost of sales as a percentage of restaurant sales
during the current quarter increased to 25.2% from 24.8% in the same quarter
last year.  This increase was attributed to modest fluctuations in ingredient
costs.

         For the 28 weeks ended July 12, 1996, cost of sales as a percentage of
restaurant sales was 25.1% compared to 24.9% during the same period last year.

         Restaurant operating expenses decreased $41,000, or 1.8%, in the
second quarter of 1996, as compared with the second quarter of 1995.  As a
percentage of restaurant sales, restaurant operating expenses decreased to
55.9% in the current quarter, as compared to 59.0% in the same quarter last
year.  This decrease was attributed to two items.  First, the restaurant
operating expenses in the store that was closed at the end of the second
quarter of 1995 were significantly greater than those in ongoing restaurants.
Second, the 1995 restaurant operating expenses included approximately $68,000
of related party salary expense that is not a component of the current quarter
expenses.  After giving effect to these two components, restaurant operating
expenses as a percentage of restaurant sales would have been 56.0% for the
second quarter of 1995.

         For the 28-week period ended July 12, 1996, restaurant operating
expenses decreased 6.1%, or $329,000, as compared with the same period last
year.  As a





                                       7
<PAGE>   8
percentage of restaurant sales, restaurant operating expenses decreased to
55.2% from 59.5% in the same period last year.  This decrease was attributed to
the two items discussed above related to the current quarter.  Giving effect to
these, restaurant operating expenses as a percentage of restaurant sales would
have been 55.7% for the 28-week period ended July 14, 1995.

         General and administrative expenses (G&A) decreased $86,000, or 18.7%,
in the current quarter as compared with the prior year's same quarter.  As a
percentage of total revenues, G&A decreased to 8.9% in the second quarter of
1996, from 11.4% in the second quarter of 1995.  This decrease is related
primarily to two components.  First, during the current quarter, a $50,000
royalty reserve was reversed when payment was received.  Second, included in
1995 G&A was approximately $121,000 of related party expense that is not a
component of the current quarter expenses.  After giving effect to this, G&A as
a percentage of total revenues would have been 8.4% for the quarter ended July
14, 1995.  The decrease in G&A as a percentage of total revenues was partially
offset by an increase in several G&A categories for expenses that relate to
being publicly traded and to the Company's preparation for growth, including
directors and officers liability insurance, directors' fees, legal expenses and
travel.

         For the 28 weeks ended July 12, 1996, G&A increased $29,000, or 2.7%,
over the same period a year ago.  As a percentage of total revenues, G&A was
11.4%, up slightly from 11.3% for the same period last year.  Removing the
effect of various related party pro forma expenses that occurred prior to the
initial public offering, G&A as a percentage of total revenues would have been
9.7% for the 28-week period ended July 12, 1996, as compared to 8.3% for the
same period last year.  This increase is attributed to the factors discussed
above related to the current quarter.

         Depreciation and amortization expense as a percentage of total
revenues decreased from 1.5% in the second quarter of 1995 to 0.9% in the
second quarter of 1996.  For the 28 weeks ended July 12, 1996, D&A as a
percentage of total revenues was 1.0%, as compared to 1.6% for the same period
last year.  These decreases as a percentage of total revenues were the result
of using accelerated methods of depreciation on equipment in the early years of
equipment life, combined with the relatively small amount of equipment
additions made by the Company during the current quarter and year-to-date.  As
the Company opens new restaurants, depreciation expense as a percentage of
total revenues is expected to increase.

         Other Income (Expense).  Net other income as a percentage of total
revenues increased from 0.1% in the second quarter of 1995 to 2.8% in the
second quarter of 1996.  This increase was due to a $90,000 increase in net
interest income related to the investment of the initial public offering
proceeds and approximately $25,000 in other income related to various vendor
rebates.

         For the 28-week period ended July 12, 1996, net other income as a
percentage of total revenues was 2.1%, compared to 0.3% for the same period a
year ago.  This increase





                                       8
<PAGE>   9
was due to the aforementioned items, along with a refund during the first
quarter of 1996 of approximately $60,000 related to the overpayment of rent
that occurred over the past four years.

         Income Tax Expense.  Prior to the Company's initial public offering,
substantially all of the predecessor corporations elected to be taxed as S
corporations under the provisions of Subchapter S of the Internal Revenue Code.
As a result of such election, federal income taxes on the net income of these
corporations were payable personally by the shareholders.  The provision for
income taxes reflected in the financial statements prior to the effective date
of the initial public offering is for state franchise taxes on all restaurants
and for federal income taxes on the predecessor corporations that were taxable
as C corporations.  The effective tax rates on those corporations were less
than the expected rates due to applicable graduated tax rates.  The provision
for income taxes reflected in the financial statements subsequent to the
effective date of the initial public offering reflects an estimated 37%
effective tax rate.

LIQUIDITY AND CAPITAL RESOURCES

         Net cash provided by operating activities was $1,325,000 for the 28
weeks ended July 12, 1996, compared to $626,000 for the same period last year.
This increase is attributed to an increase in net income combined with changes
in certain components of working capital.

         Capital expenditures were approximately $294,000 for the first 28
weeks of 1996 compared to approximately $44,000 for the same period of 1995.
During the current quarter the Company purchased real estate for its restaurant
in Copperas Cove, Texas.  Additionally, the Company upgraded its communication
systems at the corporate office and replaced equipment in various restaurants.

         Pursuant to the terms of the reorganization of the Company,
distributions of approximately $1.3 million that related to undistributed
income through the date of the initial public offering were made during the
second quarter to shareholders of all but one of the predecessor corporations.
Due to pending issues, the distribution related to one of the predecessor
companies has not been made.  Management anticipates the distribution will be
made during the third quarter.

         In late April 1996, the Company received the proceeds from its initial
public offering of 2,000,000 shares of Common Stock at $11.00 per share.  On
May 1, the Company used $11.35 million of the proceeds to redeem 1,135,000
shares of Common Stock owned by Michael D. Domec.  The remainder of the
proceeds, net of offering expenses, will be used to finance the development or
acquisition of additional restaurants, remodel existing restaurants, install
point of sale systems and fund general corporate expenses.





                                       9

         In July, the Company entered into a $10 million unsecured credit
agreement with NationsBank of Texas, N.A.  The facility is divided into a $4
million Revolving Line of Credit (the "Revolver) and a $6 million Advised
Guidance Loan Commitment (the "Guidance Loan").  The Revolver is to be used for
general corporate purposes, including the construction or acquisition of new
restaurants, and can be drawn on, with interest only payments, through May 31,
1998, at which time the balance will be placed in a four-year term note.  The
Guidance Loan can be used at any time through May 31, 1998, to acquire certain
operations of a specified franchisee.  Any draws will be placed in a five-year
term note from the date of funding.  The interest rate on both components of
the agreement is either the prime rate or LIBOR plus a stipulated percentage.
The Company will incur a non-use fee of 0.25% on the unused portion of the
Revolver from the date of the agreement.  At the time of funding of the
Guidance Loan, there will be a one time fee of 0.25%.  Within the terms of the
agreement, the Company must meet certain financial covenants.  As of August 20,
1996, the Company had not made any draws on the Revolver or the Guidance Loan.

         Construction is currently under way on two new restaurant sites.  The
first, in Copperas Cove, Texas, has a targeted opening date of September 30.
The second, which will be on a land lease in Bellmead (Waco), Texas, has an
anticipated opening date in November.  The Company also has real estate under
contract in two other communities in Texas.  Management has targeted December
1996 for one of the restaurant openings and early 1997 for the other opening.
In addition to the construction of new restaurants, the Company will be
remodeling several of its older locations and installing a point of sale
system.  Expenditures over the next 12 months for planned capital improvements
are currently anticipated to approximate $5.7 million exclusive of any
potential franchisee acquisitions.  Cash flow from operations and the proceeds
from the initial public offering, combined with the availability under the $10
million credit facility, are anticipated to be sufficient to fund these planned
capital expenditures.

                 (a)      Commitment.      The Bank agrees, on the terms and
conditions set forth in this Agreement and for the purposes set forth in
Section 5.4, to make Autoborrow Loan Advances to the Borrower from time to time
on any Business Day during the period from the Autoborrow Loan Activation Date
until the Autoborrow Loan Commitment Termination Date provided that (i) the
amount of  the Autoborrow Loan shall not exceed the Autoborrow Loan Commitment
and (ii) the amount of  the Autoborrow Loan plus the amount of the Revolving
Loan plus the Letter of Credit Exposure shall not exceed the lesser of (A) the
sum of the Autoborrow Loan Commitment plus the Revolving Loan Commitment or (B)
the Borrowing Base.  Within the limits expressed in this Agreement and in
accordance with the autoborrowing provisions set forth in this Section 2.1,
Autoborrow Loan Advances shall  from time to time be borrowed, prepaid, and
reborrowed.  The indebtedness of the Borrower to the Bank resulting from the
Autoborrow Loan Advances made by the Bank shall be evidenced by the Autoborrow
Loan Note.

                 (b)      Method of Advancing.  If at the close of business on
any Business Day the balance of the Autoborrow Loan Account is less than the
Autoborrow Loan Borrowing Target Amount, and provided that all conditions
precedent to the making of an Advance hereunder are satisfied, the Bank shall
make an Autoborrow Loan Advance in a multiple of the Autoborrow Loan Borrowing
Multiple to the Borrower in the smallest  amount such that following such
Autoborrow Loan Advance the balance of the Autoborrow Loan Account is equal to
or greater than the Autoborrow Loan Borrowing Target Amount unless such an
Autoborrow Loan Advance would violate the limitations set forth in paragraph
(a) above, in which case such Autoborrow Loan Advance shall be limited to and
made in the greatest amount available that would not violate such limitations.
Subject to such terms, the Bank shall make such Autoborrow Loan Advance to the
Borrower as of the close of business on such date in immediately available
funds at the Autoborrow Loan Account.

                 (c)      Prepayment.  If at the close of business on any
Business Day the balance of the Autoborrow Loan Account is greater than the
Autoborrow Loan Prepayment Target Amount by an amount equal to or greater than
the Autoborrow Loan Borrowing Multiple, the Bank shall apply funds from the
Autoborrow Loan Account in excess of the Autoborrow Loan Prepayment Target
Amount in multiples of the Autoborrow Loan Borrowing Multiple to the prepayment
of the Autoborrow Loan, provided that if the amount





                                      -16-
<PAGE>   22
of the Autoborrow Loan is less than the Autoborrow Loan Borrowing Multiple, the
amount of such prepayment shall be limited to and made in the amount of the
Autoborrow Loan. The Bank shall make such application as of the close of
business on such date.

                 (d)      Repayment.  The Borrower shall pay to the Bank the
outstanding amount of the Autoborrow Loan on the Autoborrow Loan Maturity Date.

         2.2     Revolving Loan Facility.

                 (a)      Commitment.      The Bank agrees, on the terms and
conditions set forth in this Agreement and for the purposes set forth in
Section 5.4, to make Revolving Loan Advances to the Borrower as requested by
the Borrower from time to time on any Business Day during the period from the
date of this Agreement until the Revolving Loan Commitment Termination Date
provided that (i) the amount of  the Revolving Loan shall not exceed the
Revolving Loan Commitment and (ii) the amount of  the Autoborrow Loan plus the
amount of the Revolving Loan plus the Letter of Credit Exposure shall not
exceed the lesser of (A) the sum of the Autoborrow Loan Commitment plus the
Revolving Loan Commitment or (B) the Borrowing Base.  Within the limits
expressed in this Agreement, the Borrower may from time to time borrow, prepay,
and reborrow Revolving Loan Advances.  The indebtedness of the Borrower to the
Bank resulting from the Revolving Loan Advances made by the Bank shall be
evidenced by the Revolving Loan Note.

                 (b)      Method of Advancing.   Each Revolving Loan Advance
shall be made pursuant to a Borrowing Request given by the Borrower to the Bank
in writing or by telecopy not later than the time required pursuant to Section
2.6(a)(i) to select the interest rate basis for the Revolving Loan Advance.
Revolving Loan Advances must be made in an amount equal to or greater than the
Revolving Loan Minimum Borrowing Amount or made in the amount of the remaining
available amount of the Revolving Loan.  Each Borrowing Request shall be fully
completed and shall specify the information required therein, and shall be
irrevocable and binding on the Borrower unless such Borrowing Request is
rejected by the Bank as incomplete or improper.  Subject to the satisfaction of
all applicable conditions precedent, the Bank shall before close of business on
the date requested for such Revolving Loan Advance make such Revolving Loan
Advance available to the Borrower in immediately available funds at the
Borrower Account.

                 (c)      Prepayment.

                          (i)     The Borrower may prepay the outstanding
principal amount of the Revolving Loan pursuant to written notice given by the
Borrower to the Bank in writing or by telecopy by 2:00 pm (Houston, Texas,
time) on the same Business Day of the proposed prepayment or earlier as
required by Section 2.6(b).  Each such notice shall specify  the principal
amount and the Tranches of the Revolving Loan which shall be prepaid and the





                                      -17-
<PAGE>   23
date of the prepayment, and shall be irrevocable and binding on the Borrower.
Partial prepayments of the Revolving Loan must be made in an amount equal to or
greater than the Revolving Loan Minimum Borrowing Amount.  For each such notice
given by the Borrower, the Borrower shall prepay the Revolving Loan in the
specified amount on the specified date as set forth in such notice.  The
Borrower shall have no right to prepay any principal amount of the Revolving
Loan except as provided in this Section 2.2(c)(i).

                          (ii)    If the sum of the amount of the Autoborrow
Loan plus the amount of the Revolving Loan plus the Letter of Credit Exposure
ever exceeds the lesser of (A) the Borrowing Base or (B) the sum of the
Autoborrow Loan Commitment plus the Revolving Loan Commitment, the Borrower
shall, upon receipt of written notice of such condition from the Bank and to
the extent of such excess, first prepay to the Bank outstanding principal of
the Revolving Loan, second prepay to the Bank the outstanding principal of the
Autoborrow Loan, and third, if the Revolving Loan and the Autoborrow Loan have
been repaid in full, make deposits into the Letter of Credit Collateral Account
to provide cash collateral for the Letter of Credit Exposure, such that such
excess is eliminated.

                          (iii)   Each prepayment of principal under the
Revolving Loan pursuant to this Section 2.2(c) must be made in accordance with
the requirements of Section 2.6(b) and shall be accompanied by payment of all
accrued but unpaid interest on the principal amount prepaid in accordance with
Section 2.6(c) and (d) and all amounts due under Section 2.7.

                          (iv)    Following the Revolving Loan Commitment
Termination Date, all prepayments of the Revolving Loan shall be applied to the
required payments of principal in the inverse order of maturity.

                 (d)      Repayment.  The Borrower shall pay to the Bank the
outstanding principal amount of the Revolving Loan which is outstanding on the
Revolving Loan Commitment Termination Date in equal monthly installments of
1/48th of the outstanding principal amount of the Revolving Loan.  The first
such equal monthly installment shall be due and payable on the last day of the
first calendar month ending after the Revolving Loan Commitment Termination
Date, with subsequent equal monthly installments due and payable on the last
day of each calendar month thereafter until the Revolving Loan Maturity Date.
The Borrower shall pay to the Bank the remaining amount of the Revolving Loan
on the Revolving Loan Maturity Date.

Letter of Credit may have an expiration date later than 12 months after the
Revolving Loan Commitment Termination Date unless approved by the Bank.  Each
Letter of Credit must be in form and substance acceptable to the Bank.  The
indebtedness of the Borrower to the Bank resulting from Letters of Credit
requested by the Borrower shall be evidenced by the Letter of Credit
Applications made by the Borrower.

                 (b)      Requesting Letters of Credit.  Each Letter of Credit
shall be issued, increased, or extended pursuant to a Letter of Credit

                 (c)      Prepayments of Letters of Credit.  In the event that
any Letters of Credit shall be outstanding according to their terms after the

to any Letter of Credit and in accordance with the related Letter of Credit
Application, the Borrower agrees to pay to the Bank on demand of the Bank any
amount due to the Bank under such Letter of Credit Application.  If the
Borrower does not pay upon demand of the Bank any amount due to the Bank under
any Letter of Credit Application, in addition to any rights the Bank may





                                      -19-

such Revolving Loan Advance to the Borrower.  The Borrower hereby
unconditionally and irrevocably authorizes, empowers, and directs the Bank to
make such requests for Revolving Loan Advances on behalf of the Borrower in
satisfaction of such obligations.  The Bank may record and otherwise treat the
making of such Revolving Loan Advances as the making of a Revolving Loan
Advance to the Borrower under this Agreement as if requested by the Borrower.
Nothing herein is intended to release the Borrower's obligations under any
Letter of Credit Application, but only to provide an additional method of
payment therefor.  The making of any Advance under this Section 2.3(d) shall
not constitute a cure or waiver of any Default or Event of Default caused by
the Borrower's failure to comply with the provisions of this Agreement or any
Letter of Credit Application.

                 (e)      Obligations Unconditional.  The obligations of the

Borrower or the Bank may have at any time against any beneficiary or transferee
of any Letter of Credit (or any Persons for whom any such beneficiary or any
such transferee may be acting), the Bank, or any other Person or entity,
whether in connection with the transactions contemplated in this Agreement or
any unrelated transaction; (iv) any statement or any other document presented
under such Letter of Credit proving to be forged, fraudulent, invalid, or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; or (v) payment by the Bank under any Letter of Credit against
presentation of a draft or certificate which does not comply with the terms of
such Letter of Credit; provided, however, that nothing contained in this
paragraph (e) shall be deemed to constitute a waiver of any remedies of the
Borrower or the Bank in connection with the Letters of Credit or the Borrower's
or the Bank's rights under paragraph (f) below.

                 (f)      Liability of Bank.  The Bank shall not be liable or
responsible for:  (i) the use which may be made of any Letter of Credit or any
acts or omissions of any beneficiary or transferee in connection therewith;
(ii) the validity, sufficiency, or genuineness of documents related to Letters
of Credit, or of any endorsement thereon, even if such documents should prove
to be in any or all respects invalid, insufficient, fraudulent, or





                                      -20-
<PAGE>   26
forged; (iii) payment by the Bank against presentation of documents which do
not strictly comply with the terms of a Letter of Credit, including failure of
any documents to bear any reference or adequate reference to the relevant
Letter of Credit; or (iv) any other circumstances whatsoever in making or
failing to make payment under any Letter of Credit (INCLUDING THE BANK'S OWN
NEGLIGENCE); except that the Bank shall be liable to the Borrower to the extent
of any direct, as opposed to consequential, damages suffered by the Borrower
which the Borrower proves were caused by  the Bank's gross negligence or
willful misconduct in determining whether documents presented under a Letter of
Credit comply with the terms of such Letter of Credit.

                 (g)      Letter of Credit Collateral Account.

                          (i)     If the Borrower is required to deposit funds
in the Letter of Credit Collateral Account pursuant to paragraph (e) above or
Section 6.4, then the Borrower and the Bank shall establish the Letter of
Credit Collateral Account and the Borrower shall execute any documents and
agreements, including the Bank's standard form assignment of deposit accounts,
that the Bank requests in connection therewith to establish the Letter of
Credit Collateral Account and grant the Bank a first priority security interest
in such account and the funds therein.  The Borrower hereby pledges to the Bank
and grants the Bank a security interest in the Letter of Credit Collateral
Account, whenever established, all funds held in the Letter of Credit
Collateral Account from time to time, and all proceeds thereof as security for
the payment of the Credit Obligations.

                          (ii)    Funds held in the Letter of Credit Collateral
Account shall be held as cash collateral for obligations with respect to
Letters of Credit and promptly applied by the Bank to any reimbursement or
other obligations under Letters of Credit that exist or occur.  To the extent
that any surplus funds are held in the Letter of Credit Collateral Account
above the Letter of Credit Exposure, (A) if an Event of Default exists the Bank
may hold such surplus funds in the Letter of Credit Collateral Account as cash
collateral for the Credit Obligations or apply such surplus funds to any Credit
Obligations in accordance with Section 6.9 or (B) if no Event of Default
exists, the Bank shall release to the Borrower at the Borrower's written
request such surplus funds.

                          (iii)   Funds held in the Letter of Credit Collateral
Account shall be invested in money market funds of the Bank or in another
investment if mutually agreed upon by the Borrower and the Bank, but the Bank
shall have no other obligation to make any other investment of the funds
therein.  The Bank shall exercise reasonable care in the custody and
preservation of any funds held in the Letter of Credit Collateral Account and
shall be deemed to have exercised such care if such funds are accorded
treatment substantially equivalent to that which the Bank accords its own
property, it being understood that the Bank shall not have any responsibility
for taking any necessary steps to preserve rights against any parties with
respect to any such funds.

         2.4     Guidance Loan.

                 (a)      Nonbinding Option to Advance.  The Bank may, on the
terms and conditions set forth in this Agreement and for the purposes set forth
in Section 5.4, make Guidance Loans to the Borrower as requested by the
Borrower from time to time on any Business Day during the period from the date
of this Agreement until the Guidance Loan Commitment Termination Date provided
that (i) the aggregate outstanding principal amount of Guidance Loans shall not
exceed the Guidance Loan Commitment and (ii) the Bank shall have approved, in
its sole discretion, the amount and terms of each Guidance Loan.  Until the
Bank shall have approved any requested Guidance Loan in writing, the Bank shall
have no commitment to fund such Guidance Loan.  Within the limits expressed in
this Agreement, the Borrower may from time to time borrow, prepay, and reborrow
Guidance Loans.  The indebtedness of the Borrower to the Bank resulting from
each Guidance Loan shall be evidenced by the Guidance Loan Note made by the
Borrower in connection with such Guidance Loan.

                 (b)      Method of Advancing.  In all circumstances where the
Borrower desires a Guidance Loan, the Borrower shall provide the Bank with
information regarding the circumstances related to the proposed Guidance Loan,
obtain the written approval of the Bank as to the terms and conditions for such
Guidance Loan, and execute an appropriate Guidance Loan Note made payable to
the Bank in connection with such proposed Guidance Loan to document the terms
and conditions for the Guidance Loan.  If such approval is obtained by the
Borrower, an appropriate Guidance Loan Note has been executed and delivered by
the Borrower, and all terms and conditions have been satisfied, the approved
Guidance Loan shall be made pursuant to a request given by the Borrower to the
Bank in writing or by telecopy not later than the time required pursuant to
Section 2.6(a)(i) to select the interest rate basis for the Guidance Loan.
Each Borrowing Request shall be fully completed and shall specify the
information required therein, and shall be irrevocable and binding on the
Borrower unless such Borrowing Request is rejected by the Bank as incomplete or
improper.  Subject to the satisfaction of all applicable conditions precedent,
the Bank shall before close of business on the date requested for such Guidance
Loan make such Guidance Loan available to the Borrower in immediately available
funds at the Borrower Account.

                 (c)      Prepayment.

                          (i)     The Borrower may prepay the outstanding
principal amount of any Guidance Loan pursuant to written notice given by the
Borrower to the Bank in writing or by telecopy by 2:00 pm (Houston, Texas,
time) on the same Business Day of the proposed prepayment or earlier as
required by Section 2.6(b).  Each such notice shall specify the principal
amount and the Tranches of the Guidance Loan  which shall be prepaid and the
date of the prepayment, and shall be irrevocable and binding on the Borrower.
Partial





                                      -22-
<PAGE>   28
prepayments of Guidance Loans must be made in an amount equal to or greater
than the Guidance Loan Minimum Borrowing Amount.  For each such notice given by
the Borrower, the Borrower shall prepay the Guidance Loan in the specified
amount on the specified date as set forth in such notice.  The Borrower shall
have no right to prepay any principal amount of Guidance Loans except as
provided in this Section 2.4(c)(i).

                          (ii)    Each prepayment of principal under any
Guidance Loan pursuant to this Section 2.4(c) must be made in accordance with
the requirements of Section 2.6(b) and shall be accompanied by payment of all
accrued but unpaid interest on the principal amount prepaid in accordance with
Section 2.6(c) and (d) and all amounts due under Section 2.7.

                          (iii)   Prepayments of Guidance Loans shall be
applied in accordance with the terms of the applicable Guidance Loan Note.

                 (d)      Repayment.  The Borrower shall pay to the Bank the
outstanding principal amount of each Guidance Loan in equal monthly
installments of 1/60th of the outstanding principal amount of such Guidance
Loan.  The first such equal monthly installment shall be due and payable on the
last day of the first calendar month ending after the funding of such Guidance
Loan, with subsequent equal monthly installments due and payable on the last
day of each calendar month thereafter until the applicable Guidance Loan
Maturity Date.   The Borrower shall pay to the Bank the remaining outstanding
principal amount of  such Guidance Loan on the applicable Guidance Loan
Maturity Date.

         2.5     Fees.

                 (a)      Commitment Fee.  The Borrower shall pay to the Bank a
commitment fee equal to 0.25% per annum on the average daily amount by which
(i) the Autoborrow Loan Commitment plus the Revolving Loan Commitment exceeds
(ii) the sum of the  amount of the Autoborrow Loan plus the Revolving Loan plus
the Letter of Credit Exposure.  The commitment fee shall be due and payable
quarterly in arrears on the last day of each calendar quarter, on the
Autoborrow Loan Commitment Termination Date, and on the Revolving Loan
Commitment Termination Date.

                 (b)      Upfront Fee.  The Borrower shall pay to the Bank an
upfront fee equal to 0.25% of each Guidance Loan made pursuant to this
Agreement.  For each such Guidance Loan, such fee shall be due and payable on
the day such Guidance Loan is made.

                 (c)      Fees for Letters of Credit.  For each Letter of
Credit issued by the Bank, the Borrower shall pay to the Bank a letter of
credit fee equal to 1.50% per annum on the face amount of such Letter of Credit
for the stated term of such Letter of Credit, with a minimum fee of $750.  The
Borrower shall pay such letter of credit fees for such Letter of





                                      -23-
<PAGE>   29
Credit, including any increased amount due in respect of any increase or
extension of such Letter of Credit, on the date of the issuance, increase, or
extension of such Letter of Credit.  All such fees shall be deemed to be earned
upon the issuance, increase, or extension of such Letter of Credit, and shall
not be subject to refund in the event of the early termination of such Letter
of Credit.

         2.6     Interest.

                 (a)      Election of Interest Rate Basis.  The Borrower may
select the interest rate basis for the outstanding principal amount of each
Loan in accordance with the terms of this Section 2.6(a):

                          (i)     The Autoborrow Loan may be comprised only of
Prime Rate Tranches.  With respect to the other Loans, under the Borrowing
Request provided to the Bank in connection with the making of each Advance
under such Loans, the Borrower shall select the amount and the Type of the
Tranches, and for each LIBOR Tranche selected, any permitted Interest Period
for such LIBOR Tranche, which will comprise such Advance, provided that (A) at
no time shall there be more than five separate LIBOR Tranches outstanding
under any Loan and (B) each Tranche must be in a principal amount equal to or
greater than the Minimum LIBOR Tranche Amount and be made in multiples of the
Minimum LIBOR Tranche Multiple.  If the Borrower selects any LIBOR Tranche,
such interest rate elections must be provided to the Bank in writing or by
telecopy not later than 2:00 p.m. (Houston, Texas, time) on the third Business
Day before the date of any proposed Advance.  In the case of any Advance
including any LIBOR Tranche, upon determination by the Bank, the Bank shall
promptly notify the Borrower of the applicable interest rate to such Tranche.

                          (ii)    With respect to any Tranche under any Loan
other than the Autoborrow Loan, the Borrower may continue or convert any
portion of any LIBOR Tranche or Prime Rate Tranche to form new LIBOR Tranches
or Prime Rate Tranches under the  same Loan in accordance with this paragraph.
Each such continuation or conversion shall be made pursuant to a
Continuation/Conversion Request given by the Borrower to the Bank in writing or
by telecopy not later than 2:00 p.m. (Houston, Texas, time) on the third
Business Day before the date of the proposed continuation or conversion.  Each
Continuation/Conversion Request shall be fully completed and shall specify the
information required therein, and shall be irrevocable and binding on the
Borrower.  In the case of any continuation or conversion into LIBOR Tranches,
upon determination by the Bank, the Bank shall notify the Borrower of the
applicable interest rate.  Continuations and conversions involving LIBOR
Tranches shall be made in integral multiples of the Minimum LIBOR Tranche
Multiple.  No continuation or conversion shall be permitted if such
continuation or conversion would cause the outstanding principal amount of any
LIBOR Tranche which would remain outstanding under the Loan to be less than the
Minimum LIBOR Tranche





                                      -24-
<PAGE>   30
Amount.  At no time shall there be more than five separate LIBOR Tranches
outstanding under any Loan.  Any conversion of an existing LIBOR Tranche is
subject to Section 2.7.  Subject to the satisfaction of all applicable
conditions precedent, the Bank shall before close of business on the date
requested by the Borrower for the continuation or conversion, make such
continuation or conversion.

                          (iii)   At the end of the Interest Period for any
LIBOR Tranche if the Borrower has not continued or converted such LIBOR Tranche
into new Tranches as provided for in paragraph (ii) above, the Borrower shall
be deemed to have continued such LIBOR Tranche as a Prime Rate Tranche under
the same Loan.  Each Prime Rate Tranche shall continue as a Prime Rate Tranche
under the same Loan unless the Borrower converts such Prime Rate Tranche as
provided for in paragraph (ii) above.

                 (b)      Payments on  LIBOR Tranches.  With respect to
payments made on the outstanding principal of any Loan, subject to the other
requirements in this Agreement, the Borrower may allocate the payments among
the Tranches comprising such Loan.  Unless required by mandatory payments,
partial prepayments involving LIBOR Tranches must be made in multiples of the
Minimum LIBOR Tranche Multiple and no partial prepayment may be made if the
prepayment would cause the outstanding principal amount of any LIBOR Tranche
under any Loan to be less than the Minimum LIBOR Tranche Amount.  No voluntary
prepayment of any LIBOR Tranche may be made unless the required notice is
provided by 2:00 p.m. (Houston, Texas, time) on the third Business Day before
the date of the proposed prepayment.

                 (c)      Interest on LIBOR Tranches.  Each LIBOR Tranche shall
bear interest during its Interest Period at a per annum interest rate equal to
the sum of the LIBOR for such LIBOR Tranche plus the Applicable Interest Margin
for LIBOR Tranches in effect from time to time.  The Borrower shall pay to the
Bank all accrued but unpaid interest on each LIBOR Tranche on the last day of
the applicable Interest Period for such LIBOR Tranche (and with respect to
LIBOR Tranches with Interest Periods of greater than three months, on the date
which is three months after the first date of the Interest Period for such
LIBOR Tranche), on any date when any portion of such LIBOR Tranche is
converted, prepaid, or repaid (but only on the amount so converted, prepaid, or
repaid), and on the applicable Maturity Date for such LIBOR Tranche.

                 (d)      Interest on Prime Rate Tranches.  Each Prime Rate
Tranche shall bear interest at a per annum interest rate equal to the Prime
Rate in effect from time to time plus the Applicable Interest Margin for Prime
Rate Tranches in effect from time to time.  The Borrower shall pay to the Bank
all accrued but unpaid interest on outstanding Prime Rate Tranches under any
Loan on the last day of each month, on any date all Prime Rate Tranches under
such Loan are prepaid or repaid in full, and on the applicable Maturity Date
for such Prime Rate Tranches.

                 (e)      Prevention of Usury.

                          (i)     If the effective rate of interest contracted
for by the Bank with the Borrower under the Credit Documents, including the
stated rates of interest contracted for hereunder and any other amounts
contracted for under the Credit Documents which are deemed to be interest, at
any time exceeds the Highest Lawful Rate, then the outstanding principal amount
of the loans made by the Bank to the Borrower hereunder shall bear interest at
a rate which would make the effective rate of interest on the loans made by the
Bank to the Borrower under the Credit Documents equal the Highest Lawful Rate
until the difference between the amounts which would have been due by the
Borrower to the Bank at the stated rates and the amounts which were due by the
Borrower to the Bank at the Highest Lawful Rate (such difference being the
"Lost Interest") has been recaptured by the Bank.  If, when the loans made
hereunder are repaid in full, the Lost Interest has not been fully recaptured
by the Bank pursuant to the preceding sentence, then, to the extent permitted
by law, the interest rates charged by the Bank to the Borrower under Sections
2.6 and 6.5 hereunder shall be retroactively increased such that the effective
rate of interest on the loans made by the Bank to the Borrower under the Credit
Documents was at the Highest Lawful Rate since the effectiveness of this
Agreement to the extent necessary to recapture the Lost Interest not recaptured
pursuant to the preceding sentence and, to the extent allowed by law, the
Borrower shall pay to the Bank the amount of the Lost Interest remaining to be
recaptured by the Bank.

                          (ii)    In calculating all sums paid or agreed to be
paid to the Bank by the Borrower for the use, forbearance, or detention of
money under the Credit Documents, such amounts shall, to the extent permitted
by applicable law, be amortized, prorated, allocated, and spread in equal parts
throughout the term of the Credit Documents.

                          (iii)   NOTWITHSTANDING THE FOREGOING OR ANY OTHER
TERM IN THIS AGREEMENT AND THE CREDIT DOCUMENTS TO THE CONTRARY, it is the
intention of the Bank and the Borrower to conform strictly to any applicable
usury laws.  Accordingly, if the Bank contracts for, charges, or receives any
consideration from the Borrower which constitutes interest in excess of the
Highest Lawful Rate, then any such excess shall be canceled automatically and,
if previously paid, shall at the Bank's option be applied to the outstanding
amount of the loans made hereunder by the Bank to the Borrower or be refunded
to the Borrower.

         2.7     Breakage Costs.  If (i) any payment of principal on or any
conversion of any LIBOR Tranche is made on any date other than the last day of
the Interest Period for such LIBOR Tranche, whether as a result of any
voluntary or mandatory prepayment, any acceleration of maturity, or any other
cause, (ii) any payment of principal on any LIBOR Tranche is not made when due,
or (iii) any LIBOR Tranche is not borrowed, converted, or prepaid in accordance
with the respective notice thereof provided by the Borrower to the





                                      -26-
<PAGE>   32
Bank, whether as a result of any failure to meet any applicable conditions
precedent for borrowing, conversion, or prepayment, the cancellation of any
request for borrowing, conversion, or prepayment, the failure of the Borrower
to provide the respective notice of borrowing, conversion, or prepayment, or
any other cause not specified above which is created by the Borrower, then the
Borrower shall pay to the Bank upon demand any amounts required to compensate
the Bank for any losses, costs, or expenses, including lost profits and
administrative expenses, which are allocable to such action, including losses,
costs, and expenses related to the liquidation or reinvestment of funds
acquired or designated by the Bank to fund or maintain such LIBOR Tranche or
related to the reacquisition or redesignation of funds by the Bank to fund or
maintain such LIBOR Tranche following any liquidation or reinvestment of such
funds caused by such action.  A certificate as to the amount of such loss,
cost, or expense detailing the calculation thereof submitted by the Bank to the
Borrower shall be conclusive and binding for all purposes, absent manifest
error.

         2.8     Increased Costs.

                 (a)      Cost of Funds.  If, due to either (i) any
introduction of, change in, or change in the interpretation of any law or
regulation after the date of this Agreement or (ii) compliance with any
guideline or request from any central bank or other governmental authority
having appropriate jurisdiction (whether or not having the force of law) given
after the date of this Agreement, there shall be any increase in the costs of
the Bank allocable to (x) committing to make any Advance or obtaining funds for
the making, funding, or maintaining of any Advance in the relevant interbank
market or (y) committing to make Letters of Credit or issuing, funding, or
maintaining Letters of Credit, including in each case any increase in any
applicable reserve requirement specified by the Federal Reserve Board whether
for emergency, marginal, supplemental, or other reserves, then the Borrower
shall pay to the Bank upon demand any amounts required to compensate the Bank
for such increased costs, such amounts being due and payable upon demand by the
Bank. A certificate as to the cause and amount of such increased cost detailing
the calculation of such cost submitted by the Bank to the Borrower shall be
conclusive and binding for all purposes, absent manifest error.

                 (b)      Capital Adequacy.  If, due to either (i) any
introduction of, change in, or change in the interpretation of any law or
regulation after the date of this Agreement or (ii) compliance with any
guideline or request from any central bank or other governmental authority
having appropriate jurisdiction (whether or not having the force of law) given
after the date of this Agreement, there shall be any increase in the capital
requirements of the Bank or its parent or holding company allocable to (x)
committing to make Advances or making, funding, or maintaining Advances or (y)
committing to make Letters of Credit or issuing, funding, or maintaining
Letters of Credit, as such capital requirements are allocated by the Bank, then
the Borrower shall pay to the Bank upon demand any amounts required to
compensate the Bank or its parent or holding company for such increase in costs
(including





                                      -27-
<PAGE>   33
an amount equal to any reduction in the rate of return on assets or equity of
the Bank or its parent or holding company), such amounts being due and payable
upon demand by the Bank.  A certificate as to the cause and amounts detailing
the calculation of such amounts submitted by the Bank to the Borrower shall be
conclusive and binding for all purposes, absent manifest error.

         2.9     Illegality.  Notwithstanding any other provision in this
Agreement, if it becomes unlawful for the Bank to obtain deposits or other
funds for making or funding any LIBOR Tranche in the relevant interbank market,
the Bank shall so notify the Borrower and the Bank's commitment to create LIBOR
Tranches shall be suspended until such condition has passed, all LIBOR Tranches
applicable to the Bank shall be converted to Prime Rate Tranches as of the end
of each applicable Interest Period or earlier if necessary, and all subsequent
requests for LIBOR Tranches shall be deemed to be requests for Prime Rate
Tranches.

         2.10    Market Failure.  Notwithstanding any other provision in this
Agreement, if the Bank determines that: (a) quotations of interest rates for
the relevant deposits referred to in the definition of "LIBOR" are not being
provided in the relevant amounts, or maturities for purposes of determining the
rate of interest referred to in the definition of "LIBOR" or (b) the relevant
rates of interest referred to in the definition of "LIBOR" which are used as
the basis to determine the rate of interest for LIBOR Tranches are not likely
to adequately cover the cost to the Bank of making or maintaining any LIBOR
Tranche, then if the Bank so notifies the Borrower, the commitment of the Bank
to create LIBOR Tranches shall be suspended until such condition has passed,
all LIBOR Tranches shall be converted to Prime Rate Tranches as of the end of
each applicable Interest Period, and all subsequent requests for LIBOR Tranches
shall be deemed to be requests for Prime Rate Tranches.

         2.11    Payment Procedures and Computations.

                 (a)      Payment Procedures.  Time is of the essence in this
Agreement and the Credit Documents.  All payment hereunder shall be made in
Dollars.  The Borrower shall make each payment under this Agreement and under
the Notes not later than 2:00 pm (local time at the Applicable Lending Office)
on the day when due to the Bank at its Applicable Lending Office in immediately
available funds.  All payments by the Borrower hereunder shall be made without
any offset, abatement, withholding, or reduction.

                 (b)      Authority to Charge Accounts.  The Bank, if and to
the extent payment owed to the Bank is not made when due, may charge from time
to time against any account of the Borrower with the Bank any amount so due.
The Bank agrees promptly to notify the Borrower after any such charge and
application made by the Bank provided that the failure to give such notice
shall not affect the validity of such charge and application.

<PAGE>   34
                 (c)      Interest and Fees.  Unless expressly provided for in
this Agreement, (i) all computations of interest based on the Prime Rate shall
be made on the basis of a 365/366 day year, as the case may be,  (ii) all
computations of interest based upon the LIBOR shall be made on the basis of a
360 day year, and (iii) all computations of fees shall be made on the basis of
a 360 day year, in each case for the actual number of days (including the first
day, but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Bank of an interest
rate or fee shall be conclusive and binding for all purposes, absent manifest
error.

                 (d)      Payment Dates.  Whenever any payment shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be.
If the time for payment for an amount payable is not specified in this
Agreement or in any other Credit Document, the payment shall be due and payable
on demand by the Bank.

         2.12    Taxes. The Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges, or similar
levies which arise from any payment made or from the execution, delivery, or
registration of, or otherwise with respect to, this Agreement or the other
Credit Documents.

ARTICLE 3.       CONDITIONS PRECEDENT.

         3.1     Conditions Precedent to Initial Extensions of Credit.  The

the Bank the rights of the Bank intended to be provided thereunder. In
connection therewith, the Borrower shall provide corporate documentation and,
if requested by the Bank, opinion letters reasonably satisfactory to the Bank
reflecting the corporate status of such new Subsidiary of the Borrower and the
enforceability of such agreements.

ARTICLE 6.       DEFAULT AND REMEDIES.

         6.1     Events of Default.  The occurrence of any of the following
shall be an "Event of Default" for the purposes of this Agreement and the
Credit Documents:

                 (a)      Payment Failure.  The Borrower fails to pay when due
any principal, interest, fees, reimbursements, indemnifications, or other
amounts due under this Agreement or any other Credit Document and such failure
is not cured within 10 days;

                 (b)      False Representation.  Any written representation or
warranty made by any Credit Party or any Responsible Officer thereof in this
Agreement or in any other Credit Document proves to have been materially false
or erroneous at the time it was made or deemed made;

                 (c)      Breach of Covenant.  (i) Any breach by the Borrower
of any of the covenants contained in Section 5.1, 5.11, 5.12, 5.14, 5.15, 5.16,
5.17, or 5.19 of this Agreement, and such breach is not cured within 30 days of
the earlier of knowledge of such breach by the Borrower or the receipt of
written notice thereof from the Bank, or (ii) any breach by the Borrower of any
of the other covenant contained in this Agreement or any other Credit Document;

                 (d)      Material Debt Default.  (i) Any principal, interest,
fees, or other amounts due on any Debt of any Credit Party is not paid when
due, whether by scheduled maturity, required prepayment, acceleration, demand,
or otherwise, and such failure is not cured within the applicable grace period,
if any, and the aggregate amount of all Debt of the Credit Parties so in
default exceeds $250,000; (ii) any other event shall occur or condition shall
exist under any agreement or instrument relating to any Debt of any Credit
Party the effect of which is to accelerate or to permit the acceleration of the
maturity of any such Debt, whether or not any such Debt is actually
accelerated, and the aggregate amount of all Debt of the Credit Parties so in
default exceeds $250,000; or (iii) any Debt of any Credit Party





                                      -40-
<PAGE>   46
shall be declared to be due and payable, or required to be prepaid (other than
by a regularly scheduled prepayment) prior to the stated maturity thereof, and
the aggregate amount of all Debt of the Credit Parties so accelerated exceeds
$250,000;

                 (e)      Material Agreement Default.  There shall occur any
breach by any Credit Party of any contract or agreement which breach could
reasonably be expected to cause a Material Adverse Change and such breach is
not cured within the applicable grace period, if any;

                 (f)      Adverse Judgment.  The aggregate outstanding amount
of unpaid, final judgments against the Credit Parties not discharged or stayed
pending appeal or other court action within 30 days following entry is greater
than $250,000;

                 (g)      Bankruptcy and Insolvency.  (i) there shall have been
filed against any Credit Party or any of such Person's properties, without such
Person's consent, any petition or other request for relief seeking an
arrangement, receivership, reorganization, liquidation, or similar relief under
bankruptcy or other laws for the relief of debtors and such request for relief
(A) remains in effect for 60 or more days, whether or not consecutive, or (B)
is approved by a final  nonappealable order, or (ii) any Credit Party consents
to or files any petition or other request for relief of the type described in
clause (i) above seeking relief from creditors, makes any assignment for the
benefit of creditors or other arrangement with creditors, or admits in writing
the inability to pay debts as they become due (the occurrence of any of the
foregoing in clause (i) or clause (ii) being a "Bankruptcy Event of Default);
or

                 (h)      Guaranty.  (i) the Guaranty shall at any time and for
any reason cease to be in full force and effect or shall be contested by any
Guarantor, or any Guarantor shall deny it has any further liability or
obligation thereunder, (ii) any breach by any Guarantor of any of the covenants
contained in Sections 1.1 or 1.2 of the Guaranty, or (iii) or any breach by any
Guarantor of any other covenants contained in the Guaranty or any other Credit
Document and such breach is not cured within 30 days following the earlier of
knowledge of such breach by such Guarantor or the receipt of written notice
thereof from the Bank.

         6.2     Termination of Commitments.  Upon the occurrence of any
Bankruptcy Event of Default, all of the commitments of the Bank hereunder shall
terminate.  During the existence of any Event of Default, the Bank may declare
by written notice to the Borrower all of the commitments of the Bank hereunder
terminated, whereupon the same shall immediately terminate.

         6.3     Acceleration of Credit Obligations.  Upon the occurrence of
any Bankruptcy Event of Default, the aggregate outstanding principal amount of
all loans made hereunder, all accrued interest thereon, and all other Credit
Obligations shall immediately and





                                      -41-
<PAGE>   47
automatically become due and payable.  During the existence of any Event of
Default, the Bank may declare by written notice to the Borrower the aggregate
outstanding principal amount of all loans made hereunder, all accrued interest
thereon, and all other Credit Obligations to be immediately due and payable.
In connection with the foregoing, except for the notice provided for above, the
Borrower waives notice of intent to demand, demand, presentment for payment,
notice of nonpayment, protest, notice of protest, grace, notice of dishonor,
notice of intent to accelerate, notice of acceleration, and all other notices.

         6.4     Cash Collateralization of Letters of Credit.  Upon the
occurrence of any  Bankruptcy Event of Default, the Borrower shall pay to the
Bank an amount equal to the Letter of Credit Exposure to be held in the Letter
of Credit Collateral Account for disposition in accordance with Section 2.3(g).
During the existence of any Event of Default, the Bank may require by written
notice to the Borrower that the Borrower pay to the Bank an amount equal to the
Letter of Credit Exposure to be held in the Letter of Credit Collateral Account
for disposition in accordance with Section 2.3(g).

         6.5     Default Interest.  If any Event of Default exists, the Bank
may declare by written notice to the Borrower that the Credit Obligations
specified in such notice shall bear interest beginning on the date specified in
such notice until paid in full at the applicable Default Rate for such Credit
Obligations, and the Borrower shall pay such interest to the Bank upon demand.

         6.6     Right of Setoff.  During the existence of an Event of Default,
the Bank is hereby authorized at any time, to the fullest extent permitted by
law, to set off and apply any indebtedness owed by the Bank to the Borrower
against any and all of the obligations of the Borrower under this Agreement and
the Credit Documents, irrespective of whether or not the Bank shall have made
any demand under this Agreement or the Credit Documents and although such
obligations may be contingent and unmatured.  The Bank agrees promptly to
notify the Borrower after any such setoff and application made by the Bank
provided that the failure to give such notice shall not affect the validity of
such setoff and application.

         6.7     Actions Under Credit Documents.  Following an Event of
Default, the Bank may take any and all actions permitted under the other Credit
Documents.

         6.8     Remedies Cumulative.  No right, power, or remedy conferred to
the Bank in this Agreement and the Credit Documents, or now or hereafter
existing at law, in equity, by statute, or otherwise, shall be exclusive, and
each such right, power, or remedy shall to the full extent permitted by law be
cumulative and in addition to every other such right, power, or remedy.  No
course of dealing and no delay in exercising any right, power, or remedy
conferred to the Bank in this Agreement and the Credit Documents, or now or
hereafter existing at law, in equity, by statute, or otherwise, shall operate
as a waiver of or otherwise





                                      -42-
<PAGE>   48
prejudice any such right, power, or remedy.   No notice to or demand upon the
Borrower shall entitle the Borrower to similar notices or demands in the
future.

         6.9     Application of Payments. Prior to an Event of Default, all
payments made hereunder shall be applied to the Credit Obligations as directed
by the Borrower, subject to the rules regarding the application of payments to
certain Credit Obligations provided for hereunder and in the Credit Documents.
During the existence of an Event of Default, all payments and collections shall
be applied to the Credit Obligations in the order determined by the Bank.

ARTICLE 7.       MISCELLANEOUS.

         7.1     Expenses.  The Borrower shall pay on demand (a) all reasonable
costs and expenses of the Bank in connection with the preparation, execution,
delivery, administration, modification, and amendment of this Agreement and the
other Credit Documents and (b) all costs and expenses of the Bank in connection
with the preservation or enforcement of its respective rights under this
Agreement and the other Credit Documents, whether through negotiations, legal
proceedings, or otherwise, including in each case fees and expenses of counsel
for the Bank.  The provisions of this paragraph shall survive the repayment and
termination of the credit provided for under this Agreement and any purported
termination of this Agreement which does not expressly refer to this paragraph.

         7.2     Indemnification.  The Borrower agrees to protect, defend,
indemnify, and hold harmless the Bank and its Related Parties (for the purposes
of this Section 7.2, collectively, the "Indemnified Parties") from and against
all demands, claims, actions, suits, damages, judgments, fines, penalties,
liabilities, and costs and expenses, including costs of attorneys and related
costs of experts such as accountants (collectively, the "Indemnified
Liabilities"), actually incurred by any Indemnified Party which are related to
this Agreement, the Credit Documents, or the transactions contemplated
thereunder, INCLUDING ANY INDEMNIFIED LIABILITIES CAUSED BY ANY INDEMNIFIED
PARTY'S OWN NEGLIGENCE, but not Indemnified Liabilities which are a result of
any Indemnified Party's gross negligence or willful misconduct. The provisions
of this paragraph shall survive the repayment and termination of the credit
provided for under this Agreement and any purported termination of this
Agreement which does not expressly refer to this paragraph.

         7.3     Modifications, Waivers, and Consents.  No modification or
waiver of any provision of this Agreement or the Notes, nor any consent
required under this Agreement or the Notes, shall be effective unless the same
shall be in writing and signed by the party against whom enforcement is sought,
and then such modification, waiver, or consent shall be effective only in the
specific instance and for the specific purpose for which given.

Documents shall bind and inure to the benefit of the Borrower and its

the Notes; provided however, Chapter 15 of the Texas Credit Code does not apply
to this Agreement or the Notes.

         7.8     Arbitration.

                 (a)      Any controversy or claim between or among the parties
hereto, including those arising out of or relating to this Agreement or the
Credit Documents, including any claim based on or arising from an alleged tort,
shall be determined by binding arbitration in accordance with the Federal
Arbitration Act (or if not applicable, the applicable state law), the rules of
practice and procedure for the arbitration of commercial disputes of Judicial
Arbitration and Mediation Services, Inc. ("JAMS"), and the "special rules" set
forth in paragraph (b) below.  In the event of any inconsistency, the special
rules shall control.  Judgment upon any arbitration award may be entered in any
court having jurisdiction.  Any party to this Agreement may bring an action,
including a summary or expedited proceeding, to compel arbitration of any
controversy or claim to which this Agreement or any of the Credit Documents
applies in any court having jurisdiction over such action.

                 (b)      The arbitration shall be conducted in Houston, Texas,
and administered by JAMS, who shall appoint an arbitrator; if JAMS is unable or
legally precluded from administering the arbitration, then the American
Arbitration Association shall serve.  All arbitration hearings shall be
commenced within 90 days of the demand for arbitration; further, the arbitrator
shall only be permitted to extend the commencement of such hearing for up to an
additional 60 days and only after showing cause.   The payment of costs and
fees associated with the arbitration shall be allocated  between the parties by
the arbitrator.

                 (c)      Nothing in this Agreement shall be deemed to (i)
limit the applicability of any otherwise applicable statutes of limitation or
repose and any waivers contained in this Agreement or the Credit Documents; or
(ii) be a waiver by the Bank of the protection afforded to it by 12 U.S.C. Sec.
91 or any substantially equivalent state law; or (iii) limit the right of the
Bank hereto (A) to exercise self help remedies such as setoff, or (B) to take
action to enforce rights under any security or support for the Credit
Obligations, including foreclosing on collateral and making claims under
guaranties, or (C) to obtain from a court provisional or ancillary remedies
such as injunctive relief, writ of possession, or the appointment of a
receiver.  The Bank may exercise such self help rights, enforce rights related
to security or support, or obtain such provisional or ancillary remedies
before, during, or after the pendency of any arbitration proceeding brought
pursuant to this Agreement.  Neither this exercise of self help remedies nor
the institution or maintenance of an action for foreclosure or provisional or
ancillary remedies shall constitute a waiver of the right of any party,
including the claimant in any such action, to arbitrate the merits of the
controversy or claim occasioning resort to such remedies.
