                         ODS NETWORKS, INC. AND SUBSIDIARIES
           NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)


Note A - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X.  Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements.  In the opinion of management, all the adjustments
(consisting of normal recurring adjustments) considered necessary for fair
presentation have been included.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, EARNINGS PER SHARE, which is required to be adopted on December 31, 1997. 
At that time, the Company will be required to change the method currently used
to compute earnings per share and to restate all prior periods.  Under the new
requirements for calculating primary earnings per share, the dilutive effect of
stock options will be excluded.  The change in method is expected to have no
effect on primary earnings per share for the quarter or six months ended June
30, 1997.  The change in method is expected to have no effect on primary
earnings per share for the quarter ended June 30, 1996 and an increase in
primary earnings per share for the six months ended June 30, 1996 of $0.02 per
share.  The impact of Statement 128 on the calculation of fully diluted earnings
per share for these quarters is not expected to be significant. 

The results of operations for the six month period ending June 30, 1997 are 
not necessarily indicative of the results which may be achieved for the full 
fiscal year or for any future period.  The condensed consolidated financial 
statements included herein should be read in conjunction with the 
consolidated financial statements and notes thereto included in the Company's 
annual report on Form 10-K for the year ended December 31, 1996.

RESULTS OF OPERATIONS

    NET SALES.  Net sales for the quarter and six months ended June 30, 1997
decreased to $27.9 million and $48.0 million, respectively, compared to $31.0
million and $60.5 million, respectively, for the same periods of 1996 as sales
of the Company's new network switching products did not increase quickly enough
to offset the decrease in sales of its prior generation shared bandwidth
intelligent hubs.

    Export sales for the quarter and six months ended June 30, 1997 increased
to $8.8 million and $13.2 million, respectively, compared to $3.6 million and
$8.2 million, respectively, for the same periods of 1996 primarily due to growth
in export sales to the Asian region.

    Sales to Electronic Data Systems Corporation ("EDS") were 14.6% and 14.5%,
respectively, of net sales during the quarter and six months ended June 30,
1997, compared to 31.2% and 26.3%, respectively, of net sales for the same
periods of 1996. Sales to Sapura Holdings Sdn. Bhd. ("Sapura") were 13.9% and
8.1%, respectively, of net sales during the quarter and six months ended June
30, 1997. Direct net sales to various agencies of the U.S. Government were 13.2%
and 11.6%, respectively, of net sales during the quarter and six months ended
June 30, 1997, compared to 11.4% and 10.5%, respectively, of net sales for the
same periods of 1996. Sales to AT&T Corp. ("AT&T") were 2.7% and 3.0%,
respectively, of net sales during the quarter and six months ended June 30,
1997, compared to 8.1% and 13.6%, respectively, of net sales for the same
periods of 1996.

    GROSS PROFIT.  Gross profit decreased to $11.8 million or 42.3% of net
sales for the second quarter of 1997 compared to $15.4 million or 49.6% of net
sales for the second quarter of 1996.  Gross profit decreased to $20.8 million
or 43.3% of net sales for six months ended June 30, 1997 compared to $29.7
million or 49.1% of net sales for the same period of 1996.  Gross profit as
percentages of net sales in the quarter and six months ended June 30, 1997 were
impacted by several factors, including a decline in the net realizable value of
certain prior generation products, product mix and lower sales volumes.  Gross
profit margins in future periods may be affected by several factors such as
continued product transition, declining market demand for prior generation
products, obsolescence or surplus of inventory, shifts in product mix, changes
in channels of distribution, sales volume, fluctuation in manufacturing costs,
pricing strategies of the Company and its competitors and fluctuations in sales
of integrated third-party products. Gross profit margins are typically lower on
sales of integrated third-party products.

    SALES AND MARKETING.  Sales and marketing expenses increased to $7.9
million or 28.3% of net sales for the second quarter of 1997 from $6.4 million
or 20.6% of net sales for the second quarter of 1996.  Sales and marketing
expenses increased to $15.0 million or 31.3% of net sales for six months ended
June 30, 1997 compared to $12.3 million or 20.4% of net sales for the same
period of 1996.  The increase in sales and marketing expense was primarily due
to higher levels of staffing in sales, marketing and technical support and
associated costs.  The Company expects sales and marketing expenses to continue
to increase in amount, but may vary as a percentage of net sales in the future.

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased to
$2.8 million or 10.1% of net sales for the second quarter of 1997 from $2.4
million or 7.9% of net sales for the second quarter of 1996. Research and
development expenses increased to $5.7 million or 11.8% of net sales for six
months ended June 30, 1997 compared to $4.6 million or 7.6% of net sales for the
same period of 1996.  The increase in research and development expense was
primarily due to an increase in the number of development personnel and
increased costs related to the development and testing of new switching
products.  The Company expects to continue to invest in research and development
activities in the future in order to broaden its family of switching products.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
to $1.3 million or 4.5% of net sales for the second quarter of 1997 from $0.9


                                       -9-
<PAGE>

million or 2.9% of net sales for the second quarter of 1996. General and
administrative expenses increased to $2.5 million or 5.2% of net sales for six
months ended June 30, 1997 compared to $1.8 million or 2.9% of net sales for the
same period of 1996.  As the Company continues to expand its domestic and
foreign operations, general and administrative expenses are expected to increase
in amount, but may vary as a percentage of net sales in the future.

    INTEREST.  Net interest income increased to $0.4 million and $0.7 million,
respectively, for the quarter and six months ended June 30, 1997 compared to
$0.2 million and $0.5 million, respectively, for the same periods of 1996.  Net
interest income may vary in the future based on the Company's cash flow and rate
of return on investments. 

    INCOME TAXES.  The Company's effective income tax rate remained constant at
38.0% for the quarter and six months ended June 30, 1997 compared to the same
periods of 1996.

LIQUIDITY AND CAPITAL RESOURCES

    The Company's principal sources of liquidity at June 30, 1997 were $10.8
million of cash and cash equivalents, $15.7 million of short-term investments,
$5.5 million of highly liquid investments with a stated maturity beyond one year
and an available line of credit.  As of June 30, 1997, working capital was 
$53.2 million compared to $54.5 million as of December 31, 1996.

    Cash flows provided by operations for the first six months of 1997 were
$8.1 million, primarily due to a decrease in inventory and accounts receivable
balances partially offset by a net loss for the period.  Future fluctuations in
accounts receivable and inventory balances will be dependent upon several
factors, including but not limited to quarterly sales, ability to collect
accounts receivable timely, the Company's strategy as to building inventory in
advance of receiving orders from customers, and the accuracy of the Company's
forecasts of product demand and component requirements.

    Cash used in investing activities in the first six months of 1997 consisted
of net purchases of short-term and long-term investments of $2.4 million, and
property and equipment purchases of $1.9 million.

    Cash provided by financing activities in the first six months of 1997 was
$0.5 million, which consisted of the issuance of common stock relating to the
exercise of certain warrants and employee stock options.

    During the first six months of 1997 the Company funded its operations
solely through cash flow from operations.  In April 1997, the Company renewed
its unsecured bank line of credit agreement and increased the maximum available
borrowings under the credit facility to $15.0 million.  Borrowings under this
line are subject to certain limitations and conditions, including the
maintenance of certain financial ratios such as debt-to-equity and fixed charge
coverage ratios. Borrowings on this line accrue interest at prime with interest
due monthly and principal due April 12, 1999.  As of June 30, 1997, the Company
had no borrowings outstanding under its bank credit facility.

    The Company believes that its cash, cash equivalents and investment
balances, cash expected to be generated from operations and the availability of
borrowings under its bank credit facility will provide sufficient cash resources
to finance its operations and currently projected capital expenditures through
the remainder of 1997.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

As noted above, the foregoing discussions may include forward-looking 
statements that involve risks and uncertainties.  In addition to those 
factors discussed elsewhere in this report and those discussed in the 
Company's Annual Report on Form 10-K and other filings with the Securities 
and Exchange Commission, the Company identifies the following factors which 
could affect the Company's actual results and cause actual results to differ 
materially from those in the forward-looking statements.

TECHNOLOGICAL CHANGES.  The market for the Company's products is characterized
by frequent product introductions, rapidly changing technology and continued
evolution of new industry standards. The market for network intelligent hubs and
switches requires the Company's products to be compatible and interoperable with
products and architectures offered by various vendors, including other
networking products, workstation and personal computer architectures and
computer and network operating systems.  The Company's success will depend to a
substantial degree upon its ability to develop and introduce in a timely manner
new products and enhancements to its existing products that meet changing
customer requirements and evolving industry standards.  The development of
technologically advanced products is a complex and uncertain process requiring
high levels of innovation as well as the accurate anticipation of technological
and market trends.  There can be no assurance that the Company will be able to
identify, develop, manufacture, market and support new or enhanced products
successfully in a timely manner.  Further, the Company or its competitors may
introduce new products or product enhancements that shorten the life cycle of or
obsolete the Company's existing product lines which could have a material
adverse effect on the Company's business, operating results and financial
condition.  

COMPETITION AND MARKET ACCEPTANCE.  The market for network intelligent hubs and
switches is intensely competitive and subject to frequent product introductions
with improved price/performance characteristics.  Even if the Company does
introduce advanced products which meet evolving customer requirements in a
timely manner, there can be no assurance that the new Company products will gain
market acceptance.  Many networking companies, including Cisco Systems, Inc.
("Cisco"), Cabletron Systems, Inc. ("Cabletron"), Bay Networks, Inc.("Bay
Networks"), FORE Systems, Inc. ("FORE Systems"), Xylan Corporation ("Xylan") and
others, have substantially greater financial, technical, sales and marketing
resources, better name recognition and a larger customer base than the Company. 
In addition, many of the Company's large competitors offer customers a broader
product line which provides a more comprehensive networking solution than the
Company currently offers.  Increased competition in the networking industry
could result in significant price competition, reduced profit margins or loss of
market share, any of which could have a material adverse effect on the Company's
business, operating results and financial condition.

Cisco, Cabletron, Bay Networks, FORE Systems and other competitors have recently
acquired several networking companies with complementary technologies, and the
Company anticipates that such acquisitions will continue in the future.  These
acquisitions may permit such competitors to accelerate the development and
commercialization of broader product lines and more comprehensive networking
solutions than the Company currently offers.  In the past, the Company has
relied upon a combination of internal product development and partnerships with
other networking vendors to provide competitive networking solutions to
customers.  Certain of the recent and future acquisitions by the Company's
competitors may have the effect of limiting the Company's access to commercially
significant technologies.  Further, the business combinations and acquisitions
in the networking industry are creating companies with larger market shares,
customer 


                                      -11-
<PAGE>

bases, sales forces, product offerings and technology and marketing 
expertise.  There can be no assurance that the Company will be able to 
compete successfully in such an environment.

PRODUCT TRANSITIONS.  Once current networking products have been in the market
place for a period of time and begin to be replaced by higher performance
products (whether of the Company's or a competitor's design), the Company
expects the net sales of such networking products to decrease.  In order to
achieve revenue growth in the future the Company will be required to design,
develop and successfully commercialize higher performance products in a timely
manner.  For example, the Company believes that the market for shared bandwidth
intelligent hubs, sales of which have represented the vast majority of the
Company's net sales over the past several years, decreased over the past several
quarters and may continue to decrease as switching products with enhanced
price/performance characteristics gain market acceptance.  There can be no
assurance that the Company will be able to introduce new products and gain
market acceptance quickly enough to avoid adverse revenue transition patterns
during current or future product transitions.

MANUFACTURING AND AVAILABILITY OF COMPONENTS.  The Company's manufacturing
operations consist primarily of final assembly, testing and quality control of
subassemblies and finished units.  Materials used by the Company in its
manufacturing processes include semiconductors such as microprocessors, memory
chips and application-specific integrated circuits ("ASICs"), printed circuit
boards, power supplies and enclosures.  All of the materials used in the
Company's products are purchased under contracts and purchase orders with third
parties.  While the Company believes that many of the materials used in the
production of its products are generally readily available from a variety of
sources, certain key components are available from one or a limited number of
suppliers. For example, certain ASICs designed into the Company's InfiniteSwitch
products are supplied by FORE Systems (see Factors That May Affect Future
Results of Operations - Competition and Market Acceptance).  The lead times for
delivery of components vary significantly and exceed twelve weeks for certain
components.  If the Company should fail to forecast its requirements accurately
for components, it may experience excess inventory or shortages of certain
components which could have an adverse effect on the Company's business and
operating results.  Further, any interruption in the supply of any of these
components, or the inability of the Company to procure these components from
alternative sources at acceptable prices within a reasonable time, could have an
adverse effect on the Company's business and operating results.

THIRD-PARTY PRODUCTS.  The Company believes that it is beneficial to work with
third parties with complementary technologies to broaden the appeal of the
Company's switches and intelligent hub products.  These alliances allow ODS to
provide integrated solutions to its customers, combining ODS developed
technology with third-party products such as certain routers from Cisco and ATM
switches from FORE Systems.  As the Company also competes with these technology
partners in certain segments of the market, there can be no assurance that the
Company will have access to all of the third-party products which may be
desirable in order to offer fully integrated solutions to ODS customers.

DEPENDENCE ON KEY CUSTOMERS.  A relatively small number of customers has
accounted for a significant portion of the Company's revenue. U.S. Government
agencies and strategic network integrators, such as EDS, which purchase the
Company's products for internal use and offer the Company's products for resale,
are expected to continue to account for a substantial portion of the Company's
net revenue.  The Company continuously faces competition from Cisco, Cabletron,
Bay Networks and others for U.S. Government networking projects and corporate
networking installations.  Any reduction or delay in sales of the Company's
products to these customers could have a material adverse effect on the
Company's operating results.


                                      -12-
<PAGE>

INTERNATIONAL OPERATIONS.  Export sales accounted for approximately 31.7% of the
Company's revenue for the three months ended June 30, 1997.  The Company intends
to expand its international presence and expects that export sales will
represent a significant portion of its business in the future.  While the
Company's current products are designed to meet relevant regulatory requirements
of the foreign markets in which they are sold, any inability to obtain any
required foreign regulatory approvals on a timely basis could have a material
adverse effect on the Company's operating results.  Additionally, the Company's
international operations may be affected by changes in demand resulting from
fluctuations in currency exchange rates and local purchasing practices,
including seasonal fluctuations in demand, as well as by risks such as increases
in duty rates, difficulties in distribution and other constraints upon
international trade.

INTELLECTUAL PROPERTY.  The Company's success and its ability to compete are
dependent, in part, upon its proprietary technology.  The Company does not hold
any issued patents and currently relies on a combination of contractual rights,
trade secrets and copyright laws to establish and protect its proprietary rights
in its products.  There can be no assurance that the steps taken by the Company
to protect its intellectual property will be adequate to prevent
misappropriation of its technology or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technology.

The Company is also subject to the risk of adverse claims and litigation
alleging infringement of intellectual property rights of others.  The Company
could incur substantial costs in defending itself and its customers against any
such claim regardless of the merits of such claims.  In the event of a
successful claim of infringement, the Company may be required to obtain one or
more licenses from third parties.  There can be no assurance that the Company
could obtain the necessary licenses on reasonable terms.

GENERAL.  Sales of networking products fluctuate, from time to time, based on
numerous factors, including customers' capital spending levels and general
economic conditions.  There can be no assurance as to the rate or extent of the
growth of the market for network intelligent hubs and switches or the potential
adoption of alternative technologies.  Future declines in networking product
sales as a result of general economic conditions, adoption of alternative
technologies or any other reason could have a material adverse effect on the
Company's business, operating results and financial condition.

Due to the factors noted above and elsewhere in Management's Discussion and
Analysis of Financial Condition and Results of Operations, the Company's future
earnings and stock price may be subject to significant volatility, particularly
on a quarterly basis.  Past financial performance should not be considered a
reliable indicator of future performance and investors should not use historical
trends to anticipate results or trends in future periods.  Any shortfall in
revenue and earnings from the levels anticipated by securities analysts could
have an immediate and significant effect on the trading price of the Company's
common stock in any given period.  Also, the Company participates in a highly
dynamic industry which often results in volatility of the Company's common stock
price.

                           REVOLVING CREDIT LOAN AGREEMENT


    This Second Amended and Restated Revolving Credit Loan Agreement (the "LOAN
AGREEMENT") dated as of the 12th day of April, 1997, is entered into by and
between Optical Data Systems, Inc., a Texas corporation (the "BORROWER") and
NationsBank of Texas, N.A., formerly known as NCNB Texas National Bank (the
"BANK").

                                 W I T N E S S E T H:

    WHEREAS, Borrower and Bank have entered into that certain Amended and
Restated Revolving Credit Loan Agreement dated as of April 30, 1995 (the "PRIOR
LOAN AGREEMENT"), pursuant to which Bank agreed to loan Borrower up to
$5,000,000 to fund working capital needs (the "PRIOR LOAN"), which Prior Loan
matures April 14, 1997; and

    WHEREAS, Borrower has requested that Bank renew, extend and increase the
Prior Loan; and

    WHEREAS, Bank is willing to renew, extend and increase the Prior Loan
pursuant to the terms and conditions set forth herein; and

     WHEREAS, Borrower and Bank wish to restate in its entirety the Prior Loan
Agreement and set forth the terms and conditions of the renewal, extension and
increase of the Prior Loan;

    NOW, THEREFORE, in consideration of the mutual promises herein contained
and for other valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the Prior Loan Agreement is hereby restated in its entirety

Rate from time to time in effect, plus two percent, (b) for Eurodollar Advances,

principal and interest, shall be maintained by Bank in its records, and the
aggregate unpaid principal amount shown on such records shall be rebuttable
presumptive evidence of the principal amount owing and unpaid on the Note.  The
failure to record any such amount on such records shall not, however, limit or
otherwise affect the obligations of Borrower hereunder or under the Note to
repay the principal amount of the Advance together with all interest accruing
thereon.

<PAGE>

    2.3. PROCEDURE FOR ADVANCES.  Borrower shall give Bank prior verbal notice
on or before 12:00 noon (Dallas, Texas time) on any day a Prime Rate Advance is

requested Prime Rate Advance in immediately available funds.  Borrower shall
give Bank prior written notice on or before 12:00 noon (Dallas, Texas time) at
least two Eurodollar Business Days prior to the day a Eurodollar Advance is

2:00 p.m., Dallas, Texas time, on the date specified, subject to the terms and
conditions of this Loan Agreement, Bank shall make available to Borrower at

    2.4. COMMITMENT FEES.  Borrower agrees to pay Bank a commitment fee of 
two-tenths of one percent (0.20%) per annum on the daily unused portion of

quarterly in arrears on the last day of each June, September, December and 
March, commencing June 30, 1997 (which payment shall cover the period from

long as the Revolving Credit Commitment is in effect, and shall also be 
payable at the maturity of the Note and upon the date of prepayment in full 
of the Note if the Revolving Credit Commitment is thereupon terminated.  
Borrower acknowledges and agrees that the commitment fees payable hereunder 
are bona fide commitment fees and are intended as reasonable compensation to 
Bank for committing to make funds available to Borrower as described herein 
and for no other purpose.

    2.5. LETTERS OF CREDIT.  At the request of Borrower, and upon execution of
letter of credit documentation satisfactory to Bank (including, without
limitation, an Application and Agreement for Commercial Letter of Credit [for
documentary letters of credit] or Standby Letter of Credit Application and
Agreement [for standby letters of credit] for each such letter of credit in the
form attached hereto as EXHIBIT "D") (the "APPLICATION"), Bank shall issue
documentary or standby letters of credit ("LETTERS OF CREDIT") from time to time
for the account of Borrower in a face amount not exceeding in the aggregate at
any time outstanding the lesser of (a) $5,000,000, or (b) $15,000,000 MINUS the
aggregate outstanding principal balance of all Advances.  The Revolving Credit
Commitment shall at all times be reduced by the aggregate face amount of
outstanding Letters of Credit.  The Letters of Credit shall be on terms mutually
acceptable to Bank and Borrower and no Letter of Credit shall have an expiration
date later than one hundred eighty days after the Termination Date.  Any amount
paid by Bank on any Letter of Credit which is not immediately reimbursed by
Borrower shall be treated as an Advance without the necessity for any request by
Borrower.  Borrower shall pay to Bank, at the time of issuance of each
documentary Letter of Credit, a fee equal to one and one-quarter of one percent
(1.25%) per annum times the face amount of the Letter of Credit for the period
the Letter of Credit is to be outstanding.  Borrower shall pay to Bank, at the
time of issuance of each standby Letter of Credit, a fee equal to two percent
(2%) per annum times the face amount of the Letter of Credit for the period the
Letter of Credit is to be outstanding.  In connection with the issuance of any
Letters of Credit, Borrower shall pay to Bank its standard fees and charges,
including the standard fees and charges provided for in the Application.  The

         Eurodollar Business Days' prior written notice from Borrower to Bank
         specifying the commencement date and length of the applicable Interest
         Period selected by Borrower, Borrower may convert an amount equal to
         $500,000 or an integral multiple of $50,000 in excess thereof, of any
         outstanding Prime Rate Advance into a Eurodollar Advance.

                   (b)  CONVERSION FROM EURODOLLAR ADVANCES.  Unless Bank shall
         have actually received written notice from Borrower requesting
         otherwise, delivered in accordance with SECTION 2.6(C) below, at least
         three (3) Eurodollar Business Days prior to the Final Interest Payment
         Date with respect to a Eurodollar Advance, then on such Final Interest
         Payment Date the outstanding Eurodollar Advance shall be converted to
         a Prime Rate Advance.

                   (c)  ROLLOVER.  Provided that no Event of Default shall have
         occurred and be continuing, at least three (3) Eurodollar Business
         Days prior to the Final Interest Payment Date of each Eurodollar

         portion of such Eurodollar Advance shall continue as a Eurodollar
         Advance upon the expiration of the then-current Interest Period (the
         "ROLLOVER NOTICE").  Such Rollover Notice shall also specify the
         length of the succeeding Interest Period selected by Borrower with
         respect thereto.  Each Rollover Notice shall be effective and
         irrevocable upon receipt thereof by Bank.  If the required Rollover
         Notice shall not have been timely received by Bank, then Borrower
         shall be deemed to have elected to have such Eurodollar Advance be a
         Prime Rate Advance as provided in SECTION 2.6(B).

                   (d)  MINIMUM AMOUNTS AND NUMBER OF EURODOLLAR ADVANCES. 
         Notwithstanding any provision to the contrary contained herein, (i)

         integral multiple of $50,000 in excess thereof, and (ii) there shall
         not exist or be outstanding at any time more than an aggregate of five
         (5) Eurodollar Advances.

         (e)  LENDING OFFICE.  Bank may cause any Eurodollar Advance to be made
by its principal office or by a foreign or domestic subsidiary, affiliate,
branch or correspondent.  Notwithstanding the right of Bank to fund all or any
portion of a Eurodollar Advance in any manner that it deems appropriate, Bank
shall, regardless of the actual means of funding, be deemed to have funded the
Eurodollar Advance in accordance with the interest option from time to time
selected by Borrower.

    2.7. PROTECTION OF YIELD.

                   (a)  INCREASED COSTS, ETC.  Subject to SECTION 9.8, if at
         any time, and from time to time, Bank determines that the adoption,
         modification or implementation of, or compliance with, any applicable
         law, rule or regulation regarding taxation, required levels of
         reserves, deposits, insurance or capital (including any allocation of
         capital requirements or conditions), or similar requirements
         applicable to Bank, or any interpretation or administration thereof by
         any governmental authority, central bank or comparable agency charged
         with the interpretation, administration or compliance of or with any
         of such requirements, has or would have the effect of (i) increasing
         Bank's costs relating to the Loan, the Revolving Credit Commitment, or
         any part thereof or (ii) reducing the yield or rate of return of Bank
         on the Loan, the Revolving Credit Commitment, or any part thereof, to
         a level below that which Bank could have achieved but for the
         adoption, modification or implementation of, or compliance with, any
         such requirements, Borrower shall, within ten (10) days after any
         request by Bank, pay to Bank such additional amounts as (in Bank's
         sole judgment, after good faith and reasonable computation) will
         compensate Bank for such increase in costs or reduction in yield or
         rate of return of Bank.  No failure by Bank to demand immediately
         payment of any additional amounts payable under this SECTION 2.7(A)
         shall constitute a waiver of Bank's right to demand payment of such
         amounts at any subsequent time.  If Bank requests that Borrower pay
         additional amounts pursuant to this SECTION 2.7(A), Bank shall submit
         to Borrower a certificate, executed by Bank, as to such additional
         amounts, which certificate shall be conclusive in the absence of
         manifest error.  Such certificate shall set forth the nature of the
         occurrence giving rise to such claim for additional amounts, the
         additional amounts to be paid to Bank hereunder, and the method by
         which such amounts were determined.  In determining such amounts, Bank
         may use any reasonable averaging and attribution methods.  Any portion
         of the additional amounts required to be paid under this SECTION
         2.7(A) remaining unpaid ten (10) days after the due date thereof shall
         bear interest at the Default Rate.

                   (b)  SUBSTITUTE INTEREST RATE.  If, on or before any date on
         which a Eurodollar Rate is to be determined hereunder, Bank determines
         that deposits of United States Dollars in the appropriate amount for
         the appropriate period are not being offered in the interbank
         Eurodollar market for United States Dollars, or that by reason of
         circumstances affecting such market, adequate and reasonable means do
         not exist for ascertaining the Eurodollar Rate, then Bank shall
         promptly give notice of such determination to Borrower and such
         determination shall be conclusive and binding.  During the ten (10)
         days next following the giving of such notice, Borrower and Bank shall
         negotiate in good faith in order to arrive at a mutually satisfactory
         alternative interest rate (the "SUBSTITUTE RATE") to replace the rate
         otherwise applicable to the pertinent Eurodollar Advances of Borrower
         during the applicable Interest Period.  If, within such ten (10) day
         period, Borrower and Bank agree in writing upon a Substitute Rate,
         such rate shall be effective from the first day of such Interest
         Period.  If Bank and Borrower fail to agree upon a Substitute Rate
         within such ten (10) day period, the Substitute 

<PAGE>

         Rate applicable to the pertinent Eurodollar Advance during such 
         Interest Period shall be the interest rate applicable to a Prime 
         Rate Advance under SECTION 2.2. Bank shall inform Borrower of such 
         rate as promptly as practicable, and, if requested by Borrower, Bank 
         shall deliver to Borrower a statement reflecting the computations 
         made in determining such Substitute Rate.

                   (c)  CHANGES IN LAW RENDERING LOAN UNLAWFUL.  In the event
         that (i) any change in applicable law, treaty or regulation or the
         interpretation thereof (whether or not having the force of law) shall
         make it unlawful or impossible for Bank to make or continue to
         maintain all or any portion of a Eurodollar Advance contemplated
         hereunder, or (ii) any central bank or other fiscal, monetary or other
         authority having jurisdiction over Bank or all or any portion of a
         Eurodollar Advance shall request Bank in writing to comply with
         restrictions (whether or not having the force of law) which seek to
         prohibit Bank from making or continuing to maintain such a Eurodollar
         Advance, then Bank shall so notify Borrower, and Borrower shall, upon
         demand by Bank, either, at the option of Borrower, prepay such
         Eurodollar Advance or convert such Eurodollar Advance to a Prime Rate
         Advance in accordance with SECTION 2.6(B) hereof, except that, subject
         to the provisions of SECTION 2.7 hereof, such prepayment or conversion
         need not be effected on a Final Interest Payment Date, and upon such
         demand or upon notice by Bank, the obligation of Bank to make such
         Eurodollar Advance hereunder shall terminate.  Failure to prepay any
         such portion of a Eurodollar Advance shall be deemed an election to
         convert to a Prime Rate Advance.  Such demand or notice shall be
         accompanied by a certificate of Bank provided to Borrower as to the
         reasons why it is no longer feasible for Bank to make or continue to
         maintain such Eurodollar Advance hereunder and such certificate shall,
         in the absence of manifest error in calculation, be conclusive and
         binding.

         (d)  EURODOLLAR CONSEQUENTIAL LOSS.  Borrower agrees to indemnify and
hold harmless Bank from and against any Eurodollar Consequential Loss.  Borrower
shall pay, within five (5) Business Days following demand therefor, the amount
of any Eurodollar Consequential Loss incurred by Bank.  

                   (e)  REASONABLE EFFORTS.  Borrower and Bank will use all
         reasonable efforts to avoid or to minimize the obligation of Borrower
         to pay any amounts under this SECTION 2.7 or the subjecting of any
         payment by Borrower to any withholding tax, and Borrower will, as
         promptly as practical, notify Bank, and Bank will, as promptly as
         practicable, notify Borrower, of the existence of any event which will
         require the payment by Borrower of any such amounts or the subjecting
         of any payment by Borrower to any withholding tax; PROVIDED, HOWEVER,
         that any failure to give such prompt notification shall not in any way
         affect the rights of Bank or the obligations of Borrower hereunder.

    3.1. OPTIONAL PREPAYMENTS.  Borrower shall have the right, from time to
time, to prepay the Note, in whole or in part, without premium or penalty, upon
the payment of accrued interest on the amount prepaid to and including the date
of payment.  Prepayments of the Note shall not reduce the Revolving Credit
Commitment.

    3.2. PAYMENTS.  Principal and interest shall be due and payable as provided
in the Note and this Loan Agreement.  All payments (including prepayments) by
Borrower on account of principal, interest, and fees hereunder shall be made in
immediately available funds.  All such payments shall be made to Bank at its
principal office in Dallas, not later than 12:00 noon, Dallas, Texas time, on
the date due and funds received after that hour shall be deemed to have been
received by Bank on the next following Business Day.  If any payment is
scheduled to become due and payable on a day which is not a Business Day, such
payment shall instead become due and payable on the immediately following
Business Day and interest thereon shall be payable at the then applicable rate
during such extension.

    3.3. COMPUTATION OF INTEREST AND FEES.  Interest on the Note and the fees
shall be calculated on the basis of a year of 360 days, as the case may be, for
the actual number of days (including the first but excluding the last) elapsed. 
Any change in the interest rate on the Note resulting from a change in the Prime
Rate shall become effective as of the opening of business on the day on which
such change in the Prime Rate becomes effective.

    3.4. USE OF PROCEEDS.  Borrower represents, warrants and covenants that it
is not engaged and shall not engage in the business of extending credit for the
purposes of "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulations G, T, U or X of the Board
of Governors of the Federal Reserve System, and no part of the proceeds of the
Loan shall be used to purchase or carry any such margin stock or to reduce or
retire any indebtedness incurred for any such purposes.  If requested by Bank,
Borrower will furnish to Bank a statement in conformity with the requirements of
the Federal Reserve Form U-1 referred to in said Regulation U to the foregoing
effect.  No part of the proceeds of the Loan will be used for any purpose which
violates, or which is inconsistent with, the provisions of Regulation X of said
Board of Governors.  Portions of the Loan will be advanced from time to time by
Borrower to one or more of its Subsidiaries.

notice.

                                      SECTION 8.
                                           
                                  EVENTS OF DEFAULT
                                           
    8.1. NATURE OF EVENT.  An Event of Default shall exist hereunder if any one
or more of the following occurs and is continuing:

         8.1.1.    Borrower fails to make, when due, any payment or prepayment
    of (i) principal or interest on the Note or (ii) any fee or other
    Obligation;

         8.1.2.    Default is made in the due observance or performance by
    Borrower or any Subsidiary of any of the covenants or agreements contained
    in this Loan Agreement or in any other Security Instrument (other than
    those set forth in SECTIONS 7.5 and 7.6 hereof);

         8.1.3.    Default is made in the observance or performance by Borrower
    of any of the covenants set forth in SECTIONS 7.5 or  7.6 hereof and such
    default shall continue for thirty days;

         8.1.4.    Any Loan Paper shall in any way whatsoever cease to give
    Bank the rights, interests, remedies, powers or privileges intended to be
    created thereby;

         8.1.5.    Any statement, warranty or representation by or on behalf of
    Borrower or any Subsidiary contained in this Loan Agreement or in any other
    Loan Paper or any certificate furnished in connection with this Loan
    Agreement, proves to have been incorrect in any material respect as of the
    date made or deemed made;

         8.1.6.    Borrower or any Subsidiary shall generally not pay its debts
    as they become due or shall admit in writing its inability to pay its
    debts, or shall make a general assignment for the benefit of creditors;

         8.1.7.    Borrower or any Subsidiary shall commence any case,
    proceeding or other action seeking reorganization, rearrangement,
    adjustment, liquidation, dissolution or composition of it or him or its or
    his debts under any law relating to bankruptcy, insolvency, reorganization
    or relief of debtors, or seeking appointment of a 

<PAGE>

    receiver, trustee, custodian or other similar official of it or him or of 
    all or any substantial part of its or his property;

         8.1.8.    Any case, proceeding or other action against Borrower or any
    Subsidiary shall be commenced seeking to have an order for relief entered
    against it as debtor, seeking reorganization, rearrangement, adjustment,
    liquidation, dissolution or composition of it or its debts under any law
    relating to bankruptcy, insolvency, reorganization or relief of debtors, or
    seeking appointment of a receiver, trustee, custodian or similar official
    for it or for all or any substantial part of its property, and such case,
    proceeding or other action (i) results in the entry of an order for relief
    against it or him which is not fully stayed within seven (7) Business Days
    after the entry thereof or (ii) remains undismissed for a period of sixty
    (60) days;

         8.1.9.    Any judgment against Borrower or any attachment or other
    levy against the property of Borrower with respect to a claim remains
    unpaid, unstayed on appeal, undischarged, not bonded or not dismissed for a
    period of thirty days;

         8.1.10.   The occurrence of a "default" or an "event of default"
    pursuant to the provisions of any Loan Paper; or

         8.1.11.   Default in the payment when due (subject to any applicable
    grace period), whether by acceleration or otherwise, of any other
    Indebtedness (which in the aggregate is in excess of the principal amount
    of $500,000) for borrowed money of Borrower and such default shall continue
    for a period of thirty (30) days or Borrower fails to perform or observe in
    any material manner any material provision contained in any such
    Indebtedness for borrowed money or any agreement securing or relating to
    such Indebtedness (or any other material breach or material default under
    such indebtedness or agreement occurs) if the effect of such failure to
    perform or observe such provision (or breach or default) is to permit such
    Indebtedness to become due prior to its stated maturity or prior to its
    regularly scheduled dates of payment and such failure continues for a
    period of thirty (30) days.

    8.2. DEFAULT REMEDIES.  If an Event of Default shall have occurred, Bank
may, at its option, take one or more of the following actions: (a) declare the
entire principal and all interest accrued on the Note to be due and payable, and
such Note shall thereupon become, forthwith due and payable, without any
presentment, demand, protest, notice of protest and nonpayment, notice of
intention to accelerate, notice of acceleration, notice of default or other
notice of any kind, all of which hereby are expressly waived, (b) terminate the
Revolving Credit Commitment, (c) reduce any claim to judgment and/or (iv)
without notice of default or demand, pursue and enforce any of Bank's rights and
remedies under the Loan Papers, or otherwise provided under or pursuant to any
applicable law or agreement; provided, however, that if an Event of Default
specified in SECTION 8.1(G) or (H) above occurs, the Revolving Credit Commitment
shall be immediately terminated and the Note shall become immediately due and
payable, both as to principal and interest, without any action by Bank and
without presentment, demand, protest, notice of protest and nonpayment, notice
of intention to accelerate, notice of acceleration, notice of default or any
other notice of any kind or character, all of which are hereby expressly waived;
anything contained herein or in the Note to the contrary notwithstanding.  If
Borrower fails to pay when due the principal of, or interest on, the Note,
Borrower shall pay to the holder of such Note, to the extent permitted by
applicable law, such further amount as shall be 

<PAGE>

sufficient to cover the cost and expense of collection, including (but not 
limited to) reasonable attorneys' fees.  Bank shall be entitled to exercise 
any and all rights and remedies granted to it herein and in any of the other 
Loan Papers and under applicable law.

                                      SECTION 9.
                                           
                                  GENERAL PROVISIONS
                                           
    9.1. AMENDMENT AND WAIVER.  The provisions of the Note and the other Loan
Papers, including this Loan Agreement, may not be amended, and the observance of
any term thereof may not be waived, without the express written consent of Bank
and Borrower and/or the other Person which is a party thereto.

    9.2. DELAY NOT A WAIVER; CUMULATIVE REMEDIES.  No failure or delay on the
part of Bank in exercising any right, power or privilege under the Note or the
Loan Papers, including this Loan Agreement, shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege
thereunder preclude any other or further exercise thereof or the exercise of any
other right, power or privilege.  The rights and remedies provided in the Note
and the Loan Papers, including this Loan Agreement, are cumulative and not
exclusive of any rights or remedies provided by law, and shall include the right
to set off against the Note and all of the other obligations of Borrower to
Bank, all money or property in Bank's possession, held for, or owed to,
Borrower.

    9.3. NOTICES.  Any notice hereunder to Borrower shall be in writing and, if
mailed, shall be deemed to be given when sent by mail, return receipt requested,

warranties made in the Note and in the other Loan Papers, including this Loan
Agreement, and in any certificates delivered pursuant hereto and thereto shall
survive the execution and delivery of this Loan Agreement and the Notes and the
making of the Loans.

    9.5. SUCCESSORS AND ASSIGNS.  This Loan Agreement shall be binding upon and
inure to the benefit of Borrower and Bank and their respective successors and
assigns, except that Borrower may not assign or transfer any of its rights under

<PAGE>

    9.7. GOVERNING LAW.  THE NOTE AND THE OTHER LOAN PAPERS, INCLUDING THIS
LOAN AGREEMENT, SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS AND APPLICABLE FEDERAL LAWS, AND
SHALL BE PERFORMABLE IN DALLAS, DALLAS COUNTY, TEXAS.

    9.8. USURY.  It is the intention of the parties hereto to conform strictly
to usury laws applicable to Bank.  Accordingly, if the transactions contemplated
hereby would be usurious under applicable law (including the laws of the United
States of America and the State of Texas or any other jurisdiction whose laws
may be mandatorily applicable, notwithstanding the other provisions of this Loan
Agreement), then, in that event, notwithstanding anything to the contrary in the
Note, this Loan Agreement or in any other Loan Paper or agreement entered into
in connection with or as security for the Note, it is agreed as follows: (i) the
aggregate of all consideration which constitutes interest under law applicable
to Bank that is contracted for, taken, reserved, charged or received under the
Note, this Loan Agreement or under any of the other aforesaid Loan Papers or
agreements or otherwise in connection with the Note, shall under no
circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be credited by Bank on the principal amount of the Obligation (or,
if the principal amount of the Obligation shall have been paid in full, refunded
to Borrower); and (ii) in the event that the maturity of any or all Note is
accelerated by reason of an election of Bank resulting from any Event of Default
under this Loan Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to Bank may never include more than the maximum amount allowed by
such applicable law, and excess interest, if any, provided for in this Loan
Agreement or otherwise shall be canceled automatically as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by Bank
on the principal amount of the Obligation (or, if the principal amount of the
Indebtedness shall have been paid in full, refunded by Bank to Borrower).  To
the extent that Article 5069-1.04, as amended, of the Texas Revised Civil
Statutes is relevant to Bank for the purpose of determining the maximum lawful
rate, Bank hereby elects to determine the applicable rate ceiling under such
Article by the indicated (weekly) rate ceiling from time to time in effect,
subject to Bank's right subsequently to change such method in accordance with
applicable law.

    9.9. NON-APPLICABILITY OF TEX.  REV.  STAT.  ANN. ART. 5069 CH. 15.  Tex. 
Rev.  Stat.  Ann. art. 5069 ch. 15 (which regulates certain revolving loan
accounts and revolving triparty accounts) shall not apply to the Loan.

    9.10.     DESCRIPTIVE HEADINGS.  The captions in this Loan Agreement are
for convenience of reference only and shall not define or limit the provisions
hereof.

    9.11.     TERM OF LOAN AGREEMENT.  This Loan Agreement shall continue until
the Note shall have been paid in full and until all other liabilities and
obligations of Borrower under this Loan Agreement shall have been fully
satisfied and the Revolving Credit Commitment and all Letters of Credit
terminated in full.

    9.12.     CAPITAL ADEQUACY.  If, after the date hereof, Bank shall have
determined that either (i) the adoption of any applicable law, rule, regulation
or guideline regarding capital adequacy, or any change therein, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, of (ii) compliance by Bank (or any lending office 

<PAGE>

of Bank) with any request or directive regarding capital adequacy (whether or 
not having the force of law) of any such authority, central bank or 
comparable agency, has or would have the effect of reducing the rate of 
return on Bank's capital as a consequence of its obligations hereunder to a 
level below that which bank could have achieved but for such adoption, change 
or compliance (taking into consideration Bank's policies with respect to 
capital adequacy) by an amount deemed by Bank to be material, then from time 
to time, within ten (10) days after demand by Bank Borrower shall pay to Bank 
such additional amount of amounts as will compensate Bank for such reduction. 
 Bank will promptly notify Borrower of any event of which it has actual 
knowledge, occurring after the date thereof, which will entitle Bank to 
compensation pursuant to this SECTION 9.12. A certificate of Bank claiming 
compensation under this SECTION 9.12 and setting forth the additional amount 
of amounts to be paid to it hereunder, together with the description of the 
manner in which such amounts have been calculated, shall be conclusive in the 
absence of manifest error.  In determining such amount, Bank may use any 
reasonable averaging and attribution methods.

    9.13.     RENEWAL, EXTENSION, AMENDMENT AND RESTATEMENT.  This Loan
Agreement is entered into for purposes of renewing and extending the Loan and
other credit accommodations made pursuant to the Prior Loan Agreement and for
the purpose of amending and restating the Prior Loan Agreement.  This Agreement
shall not constitute a novation of all or any portion of the Borrower's
indebtedness or obligations evidenced by or arising under or otherwise existing
with respect to the Prior Loan Agreement or any instrument, agreement or other
documents executed or delivered in connection therewith (herein collectively
referred to as the "ORIGINAL LOAN PAPERS").  All Indebtedness and Obligations
that are owed to the Bank under the Prior Loan Agreement or under any Original
Loan Paper shall continue to exist in full force and effect. 

    9.14.     NO ORAL AGREEMENTS.  THIS AGREEMENT AND THE OTHER LOAN PAPERS AS
WRITTEN REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

    IN WITNESS WHEREOF, the parties hereto have caused this Loan Agreement to
be duly executed and delivered as of the day and year first above written.

                             BORROWER:

                            EIGHTH RENEWAL PROMISSORY NOTE
                                           
$15,000,000.00     Dallas, Texas  April 12, 1997


    FOR VALUE RECEIVED, the undersigned, OPTICAL DATA SYSTEMS, INC., a Texas
corporation ("Maker") hereby unconditionally promises to pay to the order of
NATIONSBANK OF TEXAS, N.A., formerly known as NCNB Texas National Bank
("Payee"), at 901 Main Street, Dallas Texas, or at such other address given to
Maker by Payee, the principal sum of Fifteen Million and No/100 Dollars
($15,000,000.00), or so much thereof as may be advanced prior to maturity, in
lawful money of the United States of America, together with interest (calculated
on the basis of a 360 day year), on the unpaid principal balance from day-to-day
remaining, computed from the date of advance until maturity at the rate per
annum which shall from day-to-day be equal to the lesser of (a) the Maximum
Rate, or (b) at the election of the Maker as provided in the Loan Agreement, as
amended (as hereinafter defined), (i) the Prime Rate (hereinafter defined) in
effect from day-to-day, or (ii) the Eurodollar Rate (as defined in the Loan
Agreement, as amended) plus one and one-half percent (1.5%).  If at any time and
from time to time the rate of interest calculated pursuant to item (b) above
would exceed the Maximum Rate, thereby causing the interest payable hereon to be
limited to the Maximum Rate, then any subsequent reduction in the rate specified
in item (b) above shall not reduce the rate of interest hereon below the Maximum
Rate until the total amount of interest accrued hereon from and after the date
of the first advance hereunder equals the amount of interest which would have
accrued hereon if the rate specified in item (b) above had at all times been in
effect.

    The term "Maximum Rate," as used herein, shall mean, with respect to the
holder hereof, the maximum nonusurious interest rate, if any, that at any time,
or from time to time, may be contracted for, taken, reserved, charged, or
received on the indebtedness evidenced by this Note.  To the extent that Article
5069-1.04, Title 79, Texas Revised Civil Statutes, as amended, is relevant to
any holder of this Note for the purposes of determining the Maximum Rate, the
Payee hereby notifies Maker that the "applicable rate ceiling" shall be the
"indicated rate ceiling" referred to in Article 5069-1.04(a)(1) from time to
time in effect, as limited by Article 5069-1.04(b); provided, however, that to
the extent permitted by applicable law, Payee reserves the right to change the
"applicable rate ceiling" from time to time by further notice and disclosure to
Maker; and, provided further, that the "Maximum Rate" for purposes of this Note
shall not be limited to the applicable rate ceiling under Article 5069-1.04 if
federal laws or other state laws now or hereafter in effect and applicable to
this Note (and the interest contracted for, charged and collected hereunder)
shall permit a higher rate of interest.

    As used herein, the term "Prime Rate" means the variable rate of interest
established from time to time by Payee as its Prime Interest Rate or Base Rate,
each change in the rate charged hereunder to become effective, without notice to
Maker, on the effective date of each change in the Prime Rate.  Maker
acknowledges that Payee may, from time to time, extend credit to other borrowers
at rates of interest varying from, and having no relationship to, such Prime
Interest Rate or Base Rate.

    This Note has been executed and delivered pursuant to, and is subject to
certain terms and conditions set forth in, that certain Second Amended and


<PAGE>

Restated Revolving Credit Loan Agreement (the "LOAN AGREEMENT") between Maker
and Payee, dated as of April 12, 1997, and is the "Note" referred to in the Loan
Agreement.  The Holder of this Note shall be entitled to the benefits provided
in the Loan Agreement.  Reference is made to the Loan Agreement for a statement
of (i) the obligation of Payee to advance funds hereunder, (ii) the events upon
which the maturity of this Note may be accelerated, and (iii) Maker's right to
cure certain events of default, if any, as more fully set forth therein.

    The entire unpaid principal balance of this Note shall be due and payable
in full on April 12, 1999.  Accrued and unpaid interest on this Note shall be
due and payable on each Interest Payment Date (as defined in the Loan Agreement,
as amended) and on the Termination Date (as defined in the Loan Agreement).

    All past due principal and, to the extent permitted by applicable law,
interest upon this Note shall bear interest at the Default Rate (as defined in
the Loan Agreement).

    Maker and each surety, endorser, guarantor and other party ever liable for
payment of any sums of money payable on this Note, jointly and severally waive
presentment, protest, notice of protest and non-payment, or other notice of
default, notice of acceleration and intention to accelerate, and agree that
their liability under this Note shall not be affected by any renewal or
extension in the time of payment hereof, or any indulgences, or by any release
or change in any security for the payment of this Note, and hereby consent to
any and all renewals, extensions, indulgences, releases or changes, regardless
of the number of such renewals, extensions, indulgences, releases or changes.

    No waiver by Payee of any of its rights or remedies hereunder or under any
other document evidencing or securing this Note or otherwise shall be considered
a waiver of any other subsequent right or remedy of Payee; no delay or omission
in the exercise or enforcement by Payee of any rights or remedies shall ever be
construed as a waiver of any right or remedy of Payee; and no exercise or
enforcement of any such rights or remedies shall ever be held to exhaust any
right or remedy of Payee.

    Maker reserves the right to prepay the outstanding principal balance of
this Note, in whole or in part, at any time and from time to time (subject to
the provisions of the Loan Agreement, as amended, relating to the prepayment of
Eurodollar Advances), without premium or penalty.  Any such prepayment shall be
made together with payment of interest accrued on the amount of principal being
prepaid through the date of such prepayment, and shall be applied to the
installments of principal due hereunder in the inverse order of maturity.  Any
prepayment of a Eurodollar Advance may be made only on the terms contained in
the Loan Agreement (as amended).
    Regardless of any provision contained in this Note, the Loan Agreement or
any other document executed or delivered in connection therewith, Payee shall
never be deemed to have contracted for or be entitled to receive, collect or
apply as interest on this Note, any amount in excess of the Maximum Rate, and,
in the event that Payee ever receives, collects or applies as interest any such
excess, such amount which would be excessive interest shall be applied to the
reduction of the unpaid principal balance of this Note, and, if the principal
balance of this Note is paid in full, any remaining excess shall forthwith be
paid to Maker.  In determining whether or not the interest paid or payable under
any specific contingency exceeds the Maximum Rate, Maker and Payee shall, to the
maximum extent permitted under applicable law, (i) characterize any
non-principal payment (other than payments which are 

<PAGE>

expressly designated as interest payments hereunder) as an expense or fee 
rather than as interest, (ii) exclude voluntary prepayments and the effect 
thereof, and (iii) spread the total amount of interest throughout the entire 
contemplated term of this Note so that the interest rate is uniform 
throughout such term; provided, that if this Note is paid and performed in 
full prior to the end of the full contemplated term hereof, and if the 
interest received for the actual period of existence thereof exceeds the 
Maximum Rate, if any, Payee or any holder hereof shall refund to Maker the 
amount of such excess, or credit the amount of such excess against the 
aggregate unpaid principal balance of all advances made by the Payee or any 
holder hereof under this Note at the time in question.

    This Note is being executed and delivered, and is intended to be performed
in the State of Texas.  Except to the extent that the laws of the United States
may apply to the terms hereof, the substantive laws of the State of Texas shall
govern the validity, construction, enforcement and interpretation of this Note. 
In the event of a dispute involving this Note or any other instruments executed
in connection herewith, the undersigned irrevocably agrees that venue for such
dispute shall lie in any court of competent jurisdiction in Dallas County,
Texas.

    This Note modifies in its entirety that certain Seventh Renewal Promissory
Note dated April 13, 1995, executed by Maker and payable to the order of Payee
in the original principal amount of $5,000,000.00, but does not extinguish the
indebtedness evidenced thereby.  The indebtedness evidenced hereby was
originally evidenced by that certain Promissory Note dated April 30, 1990,
executed by Maker and payable to the order of Payee in the original principal
amount of $10,000,000.00.
