                                     PART I

ITEM 1.  BUSINESS

GENERAL

    Ultrak, Inc. (the "Company" or "Ultrak") designs, manufactures, markets,
sells and services innovative electronic products and systems for use in
security and surveillance, industrial video and professional audio markets
worldwide. These products and systems include a broad line of cameras, lenses,
high-speed dome systems, monitors, switchers, quad processors, time lapse
recorders, multiplexers, video transmission systems, access control systems,
computerized observation and security systems, audio equipment and accessories.
The Company has generated rapid growth with sales increasing from $1.8 million
in 1987 to $195 million in 1998.

    It is the Company's objective to set new standards in quality, performance
and value by providing single-source Enterprise Security Solutions to its
customers in the form of integrated systems whereby all closed circuit
television ("CCTV") components, alarms, access control, and badging as well as
facility and alarm management functions and reporting are controlled from one
single console. Integrated systems better serve the end user by improving their
ease of operation, security, health/safety and loss prevention, and at the same
time reducing maintenance and training costs. Ultrak's management believes that
integrated systems provide customers maximum functionality at the lowest
possible cost.

    The Company was incorporated in Colorado in 1980 and re-incorporated in
Delaware in December 1995. In 1997, the Company built a 170,000 square foot
warehouse and headquarters facility known as the Ultrak Worldwide Support Center
located in the north Dallas suburb of Lewisville, Texas. Since January 1, 1998,
the Company's new address is 1301 Waters Ridge Drive, Lewisville, Texas 75057
and its telephone number is (972) 353-6500.

    Ultrak operates sales, distribution and manufacturing locations worldwide.
The Company has sales facilities in five U.S. cities, England, France, Germany,
Italy, Singapore, Australia, and South Africa, as well as active representation
through systems integrators in China and Brazil. The Company established a
headquarters facility in Antwerp, Belgium in 1999 to coordinate efforts among
its European operations. Customers are supported by twelve distribution centers
worldwide and manufacturing facilities located in the United States, Germany,
Australia and South Africa.

     Ultrak's products and systems include Enterprise Security Solutions and
Standard Products.

ENTERPRISE SECURITY SOLUTIONS

    As the technology leader in the security and surveillance markets, Ultrak
distinguishes itself from its competitors by providing Ultrak's Enterprise
Security Solutions ("ESS") for manufacturing facilities, airports, office
complexes, government agencies, hospitals, casinos, retail stores and other
organizations that increasingly need integrated electronic security and
surveillance systems that combine CCTV matrix switching, digital video
transmission, access control and alarm management and communications. These
products and systems also play an increasingly important role in traffic
management and public safety applications. 


    Included as part of ESS is the Company's DAVE (Duplex Analog Video Encoding)
Technology system. Ultrak's proprietary DAVE Technology(TM) System 2000 is based
on technology that provides complete and continuous video coverage using a large
array of cameras connected by a single loop of coaxial cable. The Company sells
these products and systems to distributors, dealers and systems integrators
through its own field sales personnel. ESS are customized and scaled to meet the
needs of all of the Company's customers regardless of the business size. It is
the Company's strategy to develop and acquire a comprehensive line of products
and integrated systems, build worldwide sales, service and support and provide
single-source solutions to its customers.

STANDARD PRODUCTS

    The following Ultrak standard products are sold into the professional
security and surveillance markets: cameras, lenses, domes and housings,
monitors, time-lapse and digital recorders, ruggedized cameras, monitors and
recorders for mobile video applications, digital processors (quads and
multiplexers), switchers and video management systems, video transmission
equipment, access control and facility management equipment. 



                                       2

    As CCTV becomes more affordable, small businesses and homeowners are
installing video observation systems to replace or supplement conventional alarm
systems. The consumer do-it-yourself security and surveillance market consists
of those applications in which end users purchase security and surveillance
systems and install the systems themselves in their small businesses or homes.
Video products sold into this market are characterized by affordability,
aesthetically appealing designs, ease of installation and maintenance and
mobility. The typical consumer do-it-yourself market CCTV system can be wired or
wireless and consists of a camera, a monitor, a switcher or quad processor and,
optionally, a video recorder. These products are available in either black and
white or color models. Consumer do-it-yourself CCTV products are sold through
mass merchandisers, wholesale clubs, electronic retail stores, office and
juvenile product superstores, as well as through retail catalogs.

    It is the Company's strategy to provide easy-to-install and easy-to-operate
video products and systems that are "feature rich" and affordably priced. The
Company is seeking to expand these product lines and introduce these, or similar
products and systems into the European market. These products are marketed under
the Exxis label at a certain wholesale club and under the Smart Choice and other
labels at various retail outlets. The Company sells these products through a
combination of its own sales force and manufacturer's representatives.

    The professional audio market includes public address equipment for office
complexes, hotels, airports and retail stores. In addition, this market includes
sound reinforcement systems for concert halls, churches, arenas and theaters.
Ultrak produces and markets products for professional audio and sound
reinforcement systems such as amplifiers, speakers, mixers, equalizers,
microphones, CD players, turntables and accessories. The Company sells these
systems through a direct sales force in France and other countries.

    Systems integrators, who assemble and sell equipment that incorporates video
to manufacturers that in turn use this equipment in their production processes,
typically purchase the Company's video products. Video cameras are used for
machine vision, computer imaging, robotics, microscopy, high-speed inspection
and high temperature furnace monitoring. Industrial video offers more precise
assessment than human visual inspection, and can measure image parameters which
are imperceptible to the human eye. These systems are also used to remotely
monitor automated assembly lines to ensure that each process on the assembly
line is accurately and completely performed. New industrial applications are
emerging as new equipment is developed and as production automation levels
increase.

    The Company's strategy with regard to the industrial video market is to
strengthen customer loyalty by backing-up advanced products with technical
expertise, a large variety of products and outstanding customer support. The
Company uses a combination of its own sales force and manufacturer's
representatives to sell these products to dealers and OEM accounts.

STRATEGY

    Ultrak's strategy is to develop and form relationships with its customers
and to provide them with the high quality and performance products and systems
they need and desire worldwide. Additionally, Ultrak's strategy is to provide
product improvement that is driven by customer requirements and to build
worldwide marketing capabilities to maximize market coverage and increase the
time it takes to get its products to market. The Company seeks to implement this
strategy through integration of products and security technology through ESS,
superior customer service, highly focused sales and marketing, and value
oriented products and systems, and expects to offer products, training and
service support over the Internet beginning in the second half of 1999.

ACQUISITIONS

    Acquisitions have contributed significantly to the Company's recent growth.
The Company believes that acquisitions are an effective way to obtain new CCTV
and related products and integrated systems, add experienced personnel, access
additional channels of distribution, expand into new geographic territories,
diversify its customer base and improve operating efficiencies through economies
of scale. As the security industry continues to consolidate, Ultrak will also
continue to search for growth through acquisitions. During 1996, the Company
completed three acquisitions and made a minority investment in one company
(subsequently sold in 1997). During 1997, the Company completed five
acquisitions, made a minority investment in one company and established an 80
percent-owned subsidiary in the Pacific Rim. During 1998-99, the Company
completed two acquisitions, acquired the minority interest in its Pacific Rim
subsidiary, sold one subsidiary to a third party and sold its minority
investment in one company.

MARKETING AND SALES

    Ultrak operates through highly focused selling groups organized according to
Ultrak's target markets. Ultrak's customer-focused structure allows for
individual attention to each target market, quick response to customer needs and
early identification of market requirements and new product ideas. Generally,
the Company reaches each target market through regional sales professionals
supported by telemarketing, catalogs, direct mail, magazine advertising and
industry trade shows.

    In 1998, the Company began implementing an internal reorganization of its
sales and marketing operations known as "Team Ultrak" which promotes a unified
network of sales professionals that are highly customer focused. Under this new
philosophy, product supply units, customer service units and technology units
have been unified to provide the Company's sales force with the means to better
serve customer needs. New sales teams have been established in strategic
geographic locations in the U.S. and along product lines. This team approach has
been identified as a means for integrating the sales aspects of various
operations acquired by the Company since 1995 and to encourage cross selling of
Ultrak products. Together with expansion of its sales force, the Company
anticipates that this reorganization effort and the Company's focus on providing
solution sales versus product sales will contribute substantially to the growth
in sales during 1999 and beyond.


                                       6

<PAGE>   7


    The Company uses various brand names for products sold through each of its
selling groups to maximize market penetration of each selling group, to minimize
market channel conflicts and to differentiate products by features, applications
and price. The Company's proprietary brand names, many of which are registered
trademarks, include Ultrak, Diamond Electronics, MAXPRO, VideV Systems,
Videosys, SAFEnet, Exxis, Smart Choice, BST, Industrial Vision Source and ESS.
Approximately 87% of the products sold by the Company in 1998 carried Ultrak
brand names, up from 85% in 1997 and 82% in 1996. The Company also sells brands
such as Panasonic(R), Mitsubishi(R), and Sony(R).

    Ultrak began actively pursuing the international market in 1995. In 1995 and
early 1996, Ultrak sold its products and systems in a number of countries
including Mexico, Brazil, Argentina, England, France, Germany, Denmark, India,
China, South Korea, Japan, The Philippines and Australia. Since the second
quarter of 1996, the Company acquired MAXPRO (Australia), Bisset (France), VideV
(Germany), Intervision (the UK), the Videosys Group (Italy), Philtech (South
Africa), and established a distribution company in Singapore, which has
substantially expanded the Company's presence internationally. See Note K to the
Company's Consolidated Financial Statements with respect to business segments.

PRODUCT DESIGN AND DEVELOPMENT

    In addition to traditional research and development activities, Ultrak's
engineering and product development staff worldwide works directly with its
customers to design new products and product enhancements, and coordinates with
its contract suppliers to manufacture certain Ultrak branded products. Ultrak
has developed a highly competent engineering staff to work with its selling and
marketing groups to develop new products and product line extensions that
promptly respond to customer needs on a worldwide basis. Consequently, Ultrak
believes that it can develop technologically superior products with
customer-desired performance capabilities that address new applications at lower
prices than competitive products. Increasingly, the Company's products are
computer-based and software-driven to support the integration of technologies
and functions into its customers' businesses.

    As of December 31, 1998, the Company had a full-time engineering staff of 79
employees compared to only four as of December 31, 1994. Because of the complex
and highly specialized requirements of Ultrak products and systems, these
employees are experienced in a wide range of engineering disciplines including
charged-coupled device ("CCD") technology, analog and digital signal processing,
CCTV management and switching technology, computer based access control
technology, facility management technology and high speed dome technology. In
addition, the Company's international contract manufacturers employ a number of
engineers who are primarily dedicated to research and development efforts of
products sold by Ultrak.

    In 1998, the Company introduced its DAVE Graphical User Interface (GUI).
Simple to operate and simple to learn, the DAVE GUI makes in-store loss
prevention personnel more efficient at locating, tracking and identifying
shoplifting suspects. For enterprise-wide applications, the DAVE GUI provides
touch screen control, intelligent video tracking and provides large retailers
with revolutionary capabilities for improved loss prevention. The Company also
introduced its computer-based SAFEnet-NT system, the Windows-NT(R) version of
Ultrak's flagship line of integrated access control and security systems. At the
core of the Company's ESS offerings, SAFEnet-NT provides a stable, flexible
platform for the integration of new functions and technologies. 1998 also marked
the start of a major development effort to redesign and streamline the SAFEnet
field hardware. A new distributed architecture has been developed and initial
hardware prototyped and demonstrated.

PRODUCTS AND SYSTEMS

    The Company's motto, "Quality Products That Make a Difference," encapsulates
the Company's strategy of developing technologically advanced and cost-effective
products and systems that are unique and solve customers' specific needs or
problems. Through in-house product development, and with the product lines the
Company has obtained through acquisitions, Ultrak offers a broad line of Ultrak
branded products and systems. The Company's brand names include Ultrak, Diamond
Electronics, MAXPRO, VideV Systems, Videosys, SAFEnet, Exxis, Smart Choice, BST,
Industrial Vision Source and ESS. Approximately 87% of the products sold by the
Company in 1998 carried Ultrak brand names. The Company continues to offer
brands such as Panasonic, Mitsubishi, Dedicated Micros and Sony.

    The Company's products and systems include a broad line of cameras, lenses,
high-speed dome and housings, monitors, time-lapse and digital recorders,
digital processors, switchers and video management systems, the DAVE
Technology(TM) system, video transmission equipment access control and facility
management equipment, control matrix switching systems and accessories,
professional audio products, video printers, patient education systems, video
otoscopes and furnace viewing products.

OPERATIONS

    A critical element of the Company's operations is its management information
systems. In early 1997, the Company selected SAP, a leading enterprise software
system, for its domestic information needs. As of February 1998, the Company had
successfully completed the SAP conversion process at its Lewisville, Texas
Worldwide Support Center, as well as four other domestic facilities. By mid
2000, SAP will unite Ultrak and all of its domestic subsidiaries with a common
inventory, sales and database management system. Via laptop computers, the
Ultrak domestic sales team can easily communicate with the host system from any
remote location. Internationally, the Company has selected "Exact", a
multilingual, multicurrency and Euro compliant software for its European
information needs. By the end of 1999, all of the Companies European operations
will be live on the "Exact" software and will be linked together with a common
inventory sales and financial system.

    Ultrak believes that one of the keys to its success is its commitment to be
responsive and provide excellent service to its customers. Domestic orders are
entered into the Company's Lewisville, Texas-based SAP computer system either
directly by the customer through electronic data interchange, by traveling sales
representatives using laptop computers or by in-house sales personnel. After the
computer system performs an automated check of the customer's account and credit
limit, the order is released to be shipped from available inventory at one of
the six domestic stocking warehouse locations. Because the Company maintains
domestically a relatively large inventory of products, it ships most items
within 24 hours of receipt of the order. The Company's domestic stocking
warehouse locations are Lewisville (Dallas), Texas; Broomfield (Denver),
Colorado; Rancho Cucamonga (Ontario), California; San Diego, California; Ft.
Lauderdale, Florida and Carroll (Columbus), Ohio. Approximately 71% of all
domestic shipments are made from the Lewisville, Texas warehouse.

    With respect to Ultrak branded products produced by contract manufacturers,
most of these products are made exclusively for the Company or there are limited
or no competitive sales of such products in the areas served by the Company. The
Company believes that its relationships with its contract suppliers are good. In
most of these relationships, the Company believes that the relationship is as
important to the supplier as it is to the Company. Thus, the Company believes
that there is a strong, mutually advantageous basis for the trading relationship
to continue and grow. See Note G to the Company's Consolidated Financial
Statements with regard to Major Customers and Suppliers.

    Delivery times for products manufactured abroad vary from one week to two
months, depending on the mode of transportation. Because of foreign production
lead times, the Company normally makes purchase commitments to these foreign
suppliers three to six months in advance of shipment. Therefore, management
believes it is necessary for the Company to commit to and carry larger levels of
inventory than would be necessary if it manufactured all of its products
domestically. Given order lead times, accurate inventory forecasting is
critical.

    Substantially all of the Company's purchases from its non-affiliated
contract manufacturers are made in United States Dollars with the remaining
purchases made in Japanese Yen, Australian Dollars, French Francs, German
Deutschmarks, Italian Lira, the South African Rand and English Pounds. To date,
the Company's purchases have not been materially adversely affected by
fluctuations in the valuation of any international currency. It is expected that
the Company will continue to purchase the vast majority of its products in
United States Dollars.

    To ensure complete customer service and satisfaction, Ultrak offers
third-party leasing services and after-sale service for all equipment sold by
the Company.

    Ultrak offers a limited warranty on all products shipped. The Company
generally warrants that its products will conform to Ultrak's published
specifications and be free from defects in materials and workmanship.

    When goods are delivered to Ultrak, a random sampling quality assurance
procedure is performed. Selected units are verified for functionality, proper
packaging, labeling and documentation. The Company's primary contract
manufacturer as well as VideV in Germany are ISO9001 certified. The quality
assurance procedures in the Company's Ohio plant and California facility comply
with ISO9001 specifications.

BACKLOG

    As of December 31, 1998 and 1997, the Company had approximately $13.1
million and $12.3 million respectively, in order backlog which it considered to
be firm. Because purchase orders are subject to cancellation or delay by
customers with limited or no penalty, the Company's backlog is not necessarily
indicative of future revenues or earnings. Since the Company ships most products


                                       8

<PAGE>   9

within 24 hours of receipt of the order, the Company believes that backlog is
not a significant measurement of the Company's financial position.

INTELLECTUAL PROPERTY

    As part of its ongoing engineering and development activities, Ultrak seeks
patent protection on inventions covering new products and improvements when
appropriate. Ultrak currently holds a number of United States patents and has a
number of pending patent applications. Although the Company's patents have
value, the Company believes that the success of its business depends more on
innovation, sales efforts, technical expertise and knowledge of its personnel
and other factors. The Company also relies upon trade secret protection for its
confidential and proprietary information. Many of the Company's brands are
registered trademarks owned by the Company.

COMPETITION

    The Company faces substantial competition in each of its markets.
Significant competitive factors in the Company's markets include price, quality
and product performance, breadth of product line and customer service and
support. Some of the Company's existing and potential competitors have
substantially greater financial, manufacturing, marketing and other resources
than the Company. To compete successfully, the Company must continue to make
substantial investments in its engineering and development, marketing, sales,
customer service and support activities. There can be no assurance that
competitors will not develop products that offer price or performance features
superior the Company's products.

    The Company considers its major competitors to be the CCTV and access
control operations of Sensormatic Electronics Corporation, Burle (part of
Philips Communication & Security Systems, Inc.), Panasonic, Pelco, Vicon
Industries, Inc. and Cassi Rusco.

EMPLOYEES

    As of December 31, 1998, the Company had 710 full-time employees employed
worldwide at 15 primary locations and 12 field sales offices, of which 266 were
sales and sales support personnel, 169 were warehouse/manufacturing personnel,
79 were technical/service personnel, 79 were engineering and product development
personnel and 117 were administrative and managerial personnel.

    The Company's future success will depend in large part upon its ability to
attract and retain highly skilled technical, managerial, financial and marketing
personnel, in a market where such people are in demand. No employee is
represented by a union or covered by a collective bargaining agreement and the
Company has not experienced a work stoppage or strike. The Company considers its
employee relations to be good.

    The Company has a formal employee partnership philosophy that the Company
believes contributes significantly to its success. During periodic "partners'
meetings," all employee-partners are informed about the state of the Company and
key events that took place during the preceding months and given the opportunity
to ask questions, make suggestions and comment.

    The Company's employee partnership philosophy statement is as follows:

    Ultrak's partnership philosophy is at the core of our business and extends
to our customers, suppliers and employee-partners. Each employee-partner pitches
in to get the job done, is encouraged to grow both professionally and
personally, is recognized for individual achievement, and works in a cheerful
and friendly team environment. There is no room for prima donnas or hierarchies.
All employee-partners share in the Company's profits. Ultrak extends its
partnership philosophy to its suppliers and customers as well.

ITEM 2.  PROPERTIES

    The Company moved to its new Worldwide Support Center in January 1998. The
facility is comprised of approximately 170,000 square feet of leased office and
warehouse space located on 14 acres of land in Lewisville, Texas, pursuant to a
lease with an initial term expiring in April 2003. There is adequate available
space on the premises for expansion of the Worldwide Support Center if such
expansion is deemed necessary. At the conclusion of the initial lease term, the
Company has an option to acquire the facility. The Company also leases
additional office/distribution warehouse space in Fort Lauderdale, Florida;
Westminster, Colorado; Las Vegas, Nevada; San Diego, California; Paris, France;
Preston (Manchester), England; Antwerp, Belgium; San Vendemiano (Venice), Italy;
Dusseldorf, Germany; Sydney, Australia; Kengray, South Africa and Singapore.

    The Company owns its 72,000 square foot manufacturing facility in Carroll
(Columbus), Ohio and leases its manufacturing facilities in Rancho Cucamonga,
California and Perth, Western Australia. The Company believes that its
manufacturing facilities are adequate to meet the Company's present and
anticipated manufacturing needs for products that it currently manufactures.

ITEM 3.  LEGAL PROCEEDINGS

    The Company is not aware of any pending or threatened legal proceedings to
which the Company is or may be a party, which may have a materially adverse
impact on the Company. The Company knows of no legal proceedings pending or
threatened or judgments entered against any director or officer of the Company.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

OVERVIEW

    The consolidated financial statements include the accounts of Ultrak and its
ten consolidated subsidiaries. The Company is further organized in the U.S. into
separate selling divisions; all supported by common administrative functions
such as credit, accounting, payroll, purchasing, warehousing, training and
computer support services. All significant intercompany balances and
transactions among subsidiaries and divisions have been eliminated in
consolidation.

    The Company has experienced substantial growth in recent years. Net sales
have grown from $1.8 million in 1987 to $195.2 million in 1998. Increases in net
sales have come from increased volume of sales of existing products and systems
to all of the markets served by the Company, introduction and sales of new
products and systems, creation of new selling groups to focus on new markets and
acquisitions of businesses in the security and surveillance and access control
industries.

    During 1995, the Company completed three acquisitions. The largest company
acquired was Diamond, a manufacturer of CCTV security and surveillance systems
used by large retailers, of traffic management systems used by municipalities
and of industrial systems used in hazardous settings. The transaction was
accounted for as a purchase and the operations have been included in the
Company's financial statements since July 1, 1995.

    In 1996, the Company completed three international acquisitions and made a
minority investment in a fourth company. Effective July 1, 1996, Ultrak acquired
approximately 75% of the outstanding stock of MAXPRO, a manufacturer of large
scale CCTV switching systems based in Perth, Western Australia. On February 17,
1997, the Company acquired the remainder of the outstanding stock of MAXPRO. On
September 6, 1996, Ultrak acquired and subsequently sold in September 1997 its
interest in approximately 24% of the outstanding stock of Lenel, a domestic
security access control software company. Effective October 1, 1996, Ultrak
acquired all of the outstanding share capital of Bisset, a distributor of CCTV
and professional audio products based in Paris, France. Effective December 1,
1996, Ultrak acquired all of the outstanding stock of VideV, a distributor and
manufacturer of CCTV products based in Dusseldorf, Germany. All of these
transactions were accounted for as purchases and the operations have been
included in the Company's financial statements since the dates of acquisition.

    In 1997, the Company completed five acquisitions and made a minority
investment in a sixth company. Effective February 1, 1997, Ultrak acquired all
of the outstanding stock of MDI, a manufacturer of security and access control
systems based in Rancho Cucamonga, California. Effective March 1, 1997, the
Company acquired all of the outstanding stock of Intervision, a distributor of
CCTV products and systems based in England. Effective April 1, 1997, Ultrak
acquired all of the outstanding stock of the Videosys Group, a distributor of
CCTV and security products and systems based in Italy. Also effective April 1,
1997, the Company acquired all of the outstanding stock of Veravision, a
manufacturer of intraoral dental camera products based in San Clemente,
California. Effective October 1, 1997, the Company acquired all of the
outstanding stock of Philtech, a manufacturer and distributor of CCTV switching
and control equipment based in South Africa. Effective November 1997, the
Company established an 80% owned company in Singapore. All of these transactions
were accounted for as purchases and the operations have been included in the
Company's financial statements since the dates of acquisition.

    In 1998, the Company made one acquisition and acquired the 20% minority
interest in its Singapore operation. As of February 1, 1998, the Company
acquired the net assets of Norbain-France, a distributor of CCTV products based
in Paris, France. Effective August 1, 1998, the Company sold its 90% owned
subsidiary, DVD, to a third party.

    In March 1999, the Company acquired all of the outstanding stock of ABM, a
company that develops and sells computer software for the alarm monitoring
security industry.

    Product sales are recorded when goods are shipped to the customer. Most of
the Company's sales are made to its domestic customers on Net 30 or Net 60 day
credit terms after a credit review has been performed to establish
creditworthiness and to determine an appropriate credit line. The Company's
international sales are made under varying terms depending upon the
creditworthiness of the customer, and include the use of letters of credit,
payment in advance of shipment or open trade terms. Sales to one customer
accounted for approximately 17% of total sales during 1998 and 12% of total
sales during 1996 and 1997.


                                       13

<PAGE>   14

    Cost of sales for most of the Company's products includes the cost of the
product shipped plus freight, customs and other costs associated with delivery
from foreign contract manufacturers or from domestic suppliers. Cost of sales
for products manufactured by Ultrak include material, direct labor and overhead
as well as an allocated portion of indirect overhead.

    Marketing and sales expenses are costs related to the Company's sales
efforts, which include costs incurred by both direct employees of the Company
and independent sales representatives. Marketing and sales expenses consist
primarily of salaries, commissions and related benefits, depreciation,
telephone, advertising, warranty, printing, product literature, sales promotion
and travel-related costs.

    General and administrative expenses include costs of all corporate and
general administrative functions that support the existing selling divisions as
well as provides the infrastructure for future growth. General and
administrative expenses consist primarily of salaries and related benefits of
executive, administrative, operations and engineering, research and development
personnel, legal, audit and other professional fees, supplies, other engineering
costs and travel-related costs. During 1996, 1997 and 1998 the Company added new
corporate management in several areas to help facilitate and manage its growth.

    Engineering, research and product development costs are included in general
and administrative expenses and consist primarily of salaries, overhead and
material costs associated with the development of new products offered by the
Company. All such R&D costs have been expensed when incurred. During the year
ended December 31, 1998, the Company capitalized approximately $1.0 million in
software development costs in accordance with FASB #86 primarily pertaining to
its Safenet NT software and its ESS software development projects. The Company's
investment in engineering, research and software developments increased
significantly during 1996, and have continued to increase on an absolute basis
in 1997 and 1998.

    The Company's consolidated financial statements are denominated in dollars
and, accordingly, changes in the exchange rate between the Company's
subsidiaries' local currencies and the dollar will affect the conversion of such
subsidiaries' financial results into dollars for purposes of reporting the
Company's consolidated financial results. Translation adjustments are reported
as a separate component of stockholders' equity.

    A substantial portion of the Company's purchases and sales are derived from
operations outside the United States. Since the revenues and expenses of the
Company's foreign operations are generally denominated in local currency,
exchange rate fluctuations between local currencies and the dollar subject the
Company to currency exchange risks with respect to the results of its foreign
operations. Therefore, the Company is subject to these risks to the extent that
it is unable to denominate its purchases or sales in dollars or otherwise shift
to its customers or suppliers the effects of currency exchange rate
fluctuations. Such fluctuations in exchange rates could have a material adverse
effect on the Company's results of operations. The Company did not have foreign
exchange forward or currency option contracts outstanding at December 31, 1998.

</TABLE>


YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997

    For the year ended December 31, 1998, net sales were $195.2 million, an
increase of $20.3 million (12%) over 1997. This increase was due to the effect
of the acquisitions during 1997, sales of new products introduced during late
1997 and 1998 and increased volume of sales of existing CCTV products to most of
the markets served by the Company.

    Cost of sales were $131.7 million for 1998, an increase of $10.8 million
(9%) over 1997. Gross profit margins increased to 32.6% in 1998 from 30.9% in
1997. This increase was due to the continued increased sales levels of
Ultrak-branded products, cost reductions realized on certain Ultrak-branded
products and somewhat higher margins earned on ESS and other new products
introduced during late 1997 and 1998.

    Marketing and sales expenses were $30.9 million for 1998, an increase of
$4.2 million (16%) over 1997. Marketing and sales expenses for 1998 were 15.8%
of net sales, up from 15.3% in 1997. This increase was due to the effect of
hiring additional sales, sales support and marketing personnel in conjunction
with new product introductions and resulting sales activities, as well as the
increased travel, printing, product literature, advertising and promotion costs
associated with the introduction of new products.

    General and administrative expenses were $19.9 million for 1998, an increase
of $.8 million (4%) over 1997. General and administrative expenses for 1998 were
10.2% of net sales, down from 10.9% of net sales in 1997. This decrease was a
result of less hiring and selective employee terminations later in the year and
the Company's efforts to reduce its general and administrative costs as a
percentage of sales. Depreciation and amortization expenses were $4.7 million
for 1997, an increase of $.7 million (18%) over 1997. Depreciation and
amortization expenses for 1998 were 2.4% of net sales, slightly up from 2.3% of
net sales in 1997.

    Other income was approximately $.5 million for 1998, a decrease of $2.5
million from 1997. This decrease was due to the Company's shift during mid 1997
to invest excess funds in marketable equity securities (including the investment
in Detection Systems, Inc.) instead of interest bearing investments, the use of
cash to fund the Company's stock repurchase program and the increase in expense
on bank borrowings during 1998.

YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996

    For the year ended December 31, 1997, net sales were $174.9 million, an
increase of $48.3 million (38%) over 1996. This increase was due to the effect
of new acquisitions during 1996 and 1997, sales of new products introduced
during late 1996 and 1997 and increased volume of sales of existing CCTV
products to most of the markets served by the Company.

    Cost of sales were $120.9 million for 1997, an increase of $32.1 million
(36%) over 1996, including approximately $1.0 million in provisions for excess
and obsolete inventory. Gross profit margins increased to 30.9% (to 31.5%
excluding the special provisions for excess and obsolete inventory) in 1996 from
29.9% in 1996. This increase was due to the continued increased sales levels of
Ultrak-branded products, cost reductions realized on certain Ultrak-branded
products, the effect of certain acquisitions (the manufactured products of which
carry higher gross profit margins than other products sold by the Company) and
somewhat higher margins earned on new products introduced during late 1996 and
1997.

    Marketing and sales expenses were $26.7 million for 1997, an increase of
$11.1 million (72%) over 1996. Marketing and sales expenses for 1997 were 15.3%
of net sales, up from 12.3% in 1996. This increase was due to the effect of
acquisitions during late 1996 and 1997 and the effect in 1997 of hiring
additional sales, sales support and marketing personnel in conjunction with new
product introductions and resulting sales activities, as well as the increased
travel, printing, product literature, advertising and promotion costs associated
with the introduction of new products.

    General and administrative expenses were $19.1 million for 1997, an increase
of $10.2 million (116%) over 1996, including $1.0 million in increases in
reserves for accounts receivable and other assets. General and administrative
expenses for 1997 were 10.9% (10.3% excluding the special reserves for accounts
receivable and other assets) of net sales, up from 7.0% of net sales in 1996.
This increase was a result of (i) the acquisitions in late 1996 and 1997, which
maintain certain separate administrative functions and have greater research and
development costs, as a percentage of net sales, than Ultrak's other operations
and (ii) the hiring of additional research and development and administrative
staff to support the anticipated growth in sales.

    Depreciation and amortization expenses were $4.0 million for 1997, an
increase of $2.5 million (176%) over 1996. Depreciation and amortization
expenses for 1997 were 2.3% of net sales, up from 1.1% of net sales in 1996.
This increase was a result of substantially increased goodwill amortization
related to the acquisitions in late 1996 and 1997 and increased property and
equipment.

    Special charges were $3.1 million for 1997, representing 1.8% of net sales
for 1997. Special charges consisted of (i) the write-off of computer hardware
and software made obsolete by the implementation of new software, (ii) the cost
of moving to a new headquarters building including the write-off of leasehold
improvements and other abandonment costs and (iii) implementation costs related
to new software through December 1997.

    Other income was approximately $3.0 million for 1997, an increase of $3.2
million from 1996. This increase was due primarily to interest income and gain
on sale of investments, offset partially by $697,055 in nonrecurring costs of a
terminated merger.

LIQUIDITY AND CAPITAL RESOURCES

    The Company had a net decrease in cash and cash equivalents for 1998 of
approximately $9.6 million. Net cash used in operating activities for the year
was approximately $695,000, primarily consisting of increases in accounts and
notes receivable, inventories and prepaid expenses and other current assets;
decreases in accounts payable offset partially by decreases in advances for
inventory purchases; and, increases in accrued and other current liabilities.
Net cash used in investing activities was approximately $25.7 million consisting
of cash payments for purchases of property and equipment, primarily related to
the domestic SAP computer implementation and increases in purchases of
investments, offset partially by proceeds from sale of a discontinued operation.
Cash provided by financing activities was approximately $13.8 million consisting
primarily of borrowings on its revolving line of credit, offset by the purchase
of approximately $ 27.6 million in treasury stock and the payment of dividends
on the Series A Preferred Stock.

    On February 16, 1999, the Company entered into a new three-year credit
facility with two banks. The credit facility provides for combined borrowings up
to $50.0 million, comprised of a $20.0 million term facility and a $30.0 million
revolving line of credit facility. Principal payments on the $20.0 million term
facility in the quarterly amount of $833,333 commence in April 2000. Interest is
payable quarterly at prime or LIBOR plus a range of .75% to 1.25%, depending on
the leverage ratio, as defined, for the quarter. The combined credit facility
contains certain restrictive financial and operational covenants and conditions,
including a 


                                       16

<PAGE>   17

maximum leverage ratio, a debt service ratio and minimum net worth amounts. The
Company pays a quarterly unused fee of .125% to .25%, depending on the leverage
ratio for the quarter.

As of December 31, 1998, the Company was in violation of a certain financial
covenant of it's previous $40.0 million credit facility. The Company obtained a
waiver from the previous bank on January 15, 1999 and the amount outstanding
with the previous bank was paid in full with borrowings from the new $50.0
million credit facility on February 17, 1999.

    The Company believes that internally generated funds, available borrowings
under the new credit facility and current amounts of cash will be sufficient to
meet its presently anticipated needs for working capital, capital expenditures
and acquisitions, if any, for at least the next 12 months.

DERIVATIVE FINANCIAL INSTRUMENTS

    During 1997, the Company sold equity put options covering 2.6 million
shares. As of December 31, 1998, one equity put option remained outstanding and
the Company has recorded on the balance sheet its potential repurchase
obligation related to the put option totaling $1.6 million at its exercise price
of $12.51 per share. The single remaining put option was exercised on January
13, 1999 with the Company purchasing 125,000 shares of its Common Stock.

YEAR 2000 COSTS

    The Company is aware of certain issues associated with the programming code
in certain of its existing computer hardware and software systems as the
millennium (Year 2000) approaches. The Company has designed and tested the most
current versions of its products to be year 2000 compliant. However, there can
be no assurances that the Company will not experience serious unanticipated
negative consequences and/or material costs caused by undetected errors or
defects in the technology used in the Company's products that may result in
material costs to the Company.

    The Year 2000 issue is pervasive and complex, as virtually every computer
operation in certain of its international subsidiaries could be affected in some
way by the rollover of the two-digit year value to "00". The issue is whether
systems will properly recognize date sensitive information when the year changes
to 2000. Systems that do not properly recognize such information could generate
erroneous data or cause complete system failures. With respect to its internal
systems, the Company is in the process of implementing a multi-lingual and
multi-currency enterprise software at all of Ultrak's facilities worldwide. As
of August 1998, the Company had successfully completed the conversion process to
SAP at its Worldwide Service and Support Center, as well as four other domestic
facilities. SAP's software and all associated third party applications are
represented to be Year 2000 compliant. The Company's Ohio manufacturing facility
will not be converted to SAP in 1999, but its existing business systems will be
upgraded to a Year 2000 compliant version by December 1999. The Company began
its European implementation in early March 1999 using "Exact" software, a
European multilingual, multi-currency Y2K and Euro compliant software. For all
European systems that are currently not Year 2000 compliant, the Company will
address and convert those computer systems first in its implementation plan
which should be completed by December 1999. During the years ended December 31,
1998 and 1997, the Company incurred approximately $6.3 million and $1.6 million
respectively related to its implementation of SAP in the U.S. It is expected
that the remaining phases of the "Exact" implementation will additionally cost
approximately $800,000, which will be incurred primarily in 1999. Such costs are
expected to be capitalized and amortized over the estimated useful life of the
software.

    Based upon the expected timely completion of its conversion to SAP and its
discussions with its primary suppliers and vendors, the Company does not believe
that the Year 2000 issues will have a material impact on the financial position,
results of operations or cash flows of the Company. However, there can be no
assurances that the Company will not experience serious unanticipated negative
consequences and/or material costs caused by undetected errors or defects in the
technology used in the Company's internal systems, which are composed of third
party software, third party hardware that contains embedded software and the
Company's own software products.

INFLATION

    During the years ended December 31, 1998, 1997 and 1996, the cost of
property and equipment, lease expense and salaries and wages increased modestly.
The increases have not had a material impact on the Company's results of
operations during any of the periods.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    The following discussion about the Company's market risk includes
"forward-looking statements" that involve risks and uncertainties. Actual
results could differ materially from those projected in the forward-looking
statements. The Company does not use derivative financial instruments for
speculative or trading purposes. The Company is exposed to market risk from
changes in foreign currency exchange rates, interest rates, and investment
prices, which could affect its future results of operations and financial
condition. The Company manages its exposure to these risks through its regular
operating and financing activities.

Foreign exchange

    The Company has foreign-based operations, primarily in Western Europe, which
accounted for 34% of 1998 net sales. The Company issues intercompany loans to
its foreign subsidiaries denominated in U.S. dollars, exposing the foreign
subsidiaries to the effect of changes in spot exchange rates of their local
currency relative to the U.S. dollar. In addition, many of the foreign-based
operations make sales to customers denominated in different currencies, which
carry minimal market risk because the transactions normally settle quickly. The
Company does not regularly use forward-exchange contracts to hedge these
exposures. Based on the Company's foreign currency exchange rate exposure for
intercompany borrowings of approximately $15.4 million at December 31, 1998, a
10% adverse change in currency rates would create an additional comprehensive
loss of approximately $1.5 million.

Interest rates

    The Company's credit arrangements expose it to fluctuations in interest
rates. At December 31, 1998, the Company had $37.5 million outstanding under its
revolving line of credit, which provided for interest to be paid quarterly based
on a variable rate. Thus, interest rate changes would result in a change in the
amount of interest to be paid each quarter. Based upon the interest rates and
borrowings at December 31, 1998, a 10% increase in interest rates would not
materially affect the Company's financial position, annual results of
operations, or cash flows.

Investments

    The Company is exposed to fluctuations in the stock prices of investment in
its available for sale portfolio. Market fluctuations would affect the carrying
value of investments. Based upon the holdings at December 31, 1998, a 10%
decrease in market value would not materially affect the Company's financial
position, annual results of operations, or cash flows.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

    The consolidated financial statements of the Company and its subsidiaries
that are required by this Item 8 are listed in Part IV under Item 14(a) of this
report. Such consolidated financial statements are included herein beginning on

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS




Board of Directors
Ultrak, Inc.


We have audited the accompanying consolidated balance sheets of Ultrak, Inc. and
Subsidiaries as of December 31, 1998 and 1997, and the related consolidated
statements of income, stockholders' equity, and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Ultrak, Inc. and
Subsidiaries as of December 31, 1998 and 1997, and the consolidated results of
their operations and their consolidated cash flows for each of the three years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

    transactions have been eliminated in consolidation.

    Cash and Cash Equivalents

    The Company considers all highly liquid investments with original maturities
    of three months or less to be cash equivalents.

    Restricted Cash

    Restricted cash represents collateral for outstanding equity put options.

    Investments

    The Company accounts for its investments using Statement of Financial
    Accounting Standards No. 115, "Accounting for Certain Investments in Debt
    and Equity Securities." Securities available for sale are reported at fair
    value, with unrealized gains and losses, net of tax, excluded from earnings
    and reported as a separate component or stockholders' equity. Realized gains

         POLICIES - Continued

    Property, Plant and Equipment and Depreciation

    Property, plant and equipment are carried at cost. The provision for
    depreciation is computed using the straight-line method over the estimated
    useful lives of the assets.

    Income Per Share

    The Company computes basic income per share based on the weighted average
    number of common shares outstanding. Diluted income per share is computed
    based on the weighted average number of shares outstanding, plus the number
    of additional common shares that would have been outstanding if dilutive
    potential common shares had been issued.

    Goodwill and Amortization

    Goodwill resulting from acquisitions is being amortized using the
    straight-line method over periods ranging from twenty to forty years.

    Accounting for Impairment of Long-Lived Assets

    The Company evaluates long-lived assets and intangibles held and used for
    impairment whenever events or changes in circumstances indicate that the
    carrying amounts may not be recoverable. Impairment is recognized when the
    undiscounted cash flows estimated to be generated by those assets are less
    than the carrying amounts of such assets.

    Fair Value of Financial Instruments

    The Company's financial instruments consist of cash and cash equivalents,
    notes receivable, debt and equity put options for which the fair value
    approximates the carrying value.

    Stock-Based Compensation

    The Company accounts for stock-based compensation to employees using the
    intrinsic value method. Accordingly, compensation cost for stock options is
    measured as the excess, if any, of the quoted market price of the Company's
    stock at the date of the grant over the amount an employee must pay to
    acquire the stock.

    Software Development Costs

    The Company capitalizes software development costs incurred from the time
    technological feasibility of the software is established until the software
    is ready for use in its products. Research and development costs related to
    software development are expensed as incurred. The capitalized costs relate
    to software which will become an integral part of the Company's revenue
    producing products and is amortized in relation to expected revenues from
    the product or a maximum of five years, whichever is greater. The carrying
    value of software development costs is regularly reviewed by the Company,
    and a loss is recognized when the net realizable value by product falls
    below the unamortized cost.

    Currency Translation

    Translation adjustments to the financial statements of foreign subsidiaries
    are reflected in the consolidated financial statements as a component of
    other comprehensive income.

    Use of Estimates

    In preparing financial statements in conformity with generally accepted
    accounting principles, management is required to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the financial
    statements and revenues and expenses during the reporting period. Actual
    results could differ from those estimates.

    Reclassifications

    Certain reclassifications have been made to prior years financial statements
    to conform with the 1998 presentation.

    Derivative Financial Instruments

    Equity put options on common stock represent the number of options sold at
    their respective strike price. Proceeds from the sale of equity put options
    on common stock are accounted for as additional paid-in capital.

    previous line of credit. The Company was in violation of a certain financial
    covenants and obtained a waiver on January 15, 1999. Amounts outstanding
    were paid in full with proceeds from the new $50.0 million credit facility
    on February 17, 1999. Interest on the line of credit at December 31, 1998
    was payable monthly at the bank's LIBOR rate (5.0% at December 31, 1998)
    plus 3%.


NOTE E - STOCKHOLDERS' EQUITY

    The Series A preferred stock earns dividends at the rate of 12% per annum,
    payable quarterly. All dividends accrue whether or not such dividends have
    been declared and whether or not there are profits, surplus, or other funds
    of the Company legally available for payment.

    The Company may at any time redeem all or any portion of the Series A
    Preferred Stock then outstanding at the liquidation value of $5.00 per share
    plus unpaid dividends. The holder of the Series A Preferred Stock may
    convert any or all of the 195,351 preferred shares into shares of the
    Company's common stock at any time at a conversion rate equal to 2.08 shares
    of common stock per preferred share or a total of 406,981 shares of common
    stock.

    Holders of Series A preferred stock are entitled to vote on all matters
    submitted to a vote of stockholders. Each Series A preferred share is
    entitled to voting rights equal to 16.667 shares of common stock.

    During 1997 and 1998, the Company repurchased 397,850 and 2,555,100 shares,
    respectively, of its common stock. As part of its share repurchase program,
    during 1997 the Company sold equity put options covering 2,620,000 shares
    for $4,484,310. As of December 31, 1998, 125,000 options remained
    outstanding and the Company's potential repurchase obligation under these
    options totaled approximately $1.6 million at an exercise price of $12.51
    per share. The options were exercised on January 13, 1999 and the Company
    repurchased the shares.

NOTE F - STOCK-BASED COMPENSATION

    The Company's 1988 Nonqualified Stock Option Plan (the "1988 Plan") provided
    for grants of options for up to 1,000,000 restricted shares and the 1997
    Incentive Stock Option Plan (the "1997 Plan") provides for grants of options
    for up to 400,000 shares. Shares under the 1997 Plan are awarded based upon
    the Company achieving one or more definitive performance measurements for a
    fiscal year, including minimum levels of economic value added, minimum
    levels of market value added or attainment of the financial budget. The 1997
    Plan is a formula-based plan administered by the Compensation Committee of
    the Board of Directors. Option grants under the 1997 Plan are limited to 1%
    of the outstanding common stock of the Company. At December 31, 1998,
    181,712 and 261,359 shares were available for grant under the 1988 Plan and
    the 1997 Plan, respectively.

    Option exercise prices are equal to the market price at the date of grant.
    Shares under grant generally become exercisable in five equal annual
    installments beginning one year after the date of grant, and expire after
    ten years.

    If the Company recognized compensation expense as permitted under Statement
    of Financial Accounting Standards No. 123, based upon the fair value at the
    grant date for options granted after 1994 under the 1988 Plan and 1997 Plan,
    the Company's net income from continuing operations and income per share
    would be reduced to the pro forma amounts indicated as follows:

    The fair value of these options was estimated at the date of grant using the
    Black-Scholes option pricing model with the following weighted-average
    assumptions: expected volatility of 50 to 70 percent; risk-free interest
    rates of 5.5 percent; no dividend yield; and expected lives of seven years.

    The pro forma amounts presented are not representative of the amounts that
    will be disclosed in the future because they do not take into effect pro
    forma expense related to grants before 1995.

    One customer accounted for more than 10% of revenue in each of the three
    years ended December 31, 1998. Sales to that customer were:

</TABLE>

    Loss of this customer would have a material adverse effect on the operations
    of the Company.

    The Company purchased in excess of 25% of its products from one contract
    manufacturer in each of the three years in the period ended December 31,
    1998. Although there are a limited number of manufacturers of the Company's
    products, management believes there are suppliers who could provide similar
    products on comparable terms. A change in suppliers could cause a delay in
    and a possible loss of sales.


NOTE H - COMMITMENTS AND CONTINGENCIES

    $3,473,563. All common stocks were purchased in 1998 at a cost of
    $3,733,978. The Company has classified these securities as available for

NOTE K - SEGMENT DISCLOSURE AND FOREIGN OPERATIONS

    Effective March 31, 1998, the Company adopted SFAS No. 131, Disclosures
    about Segments of an Enterprise and Related Information which changes the
    way the company reports information about its operating segments.

    The Company has three business segments: United States-Professional Security
    Group (US-PSG), United States-Diversified Group (US-DSG), and
    International-Professional Security Group (International-PSG). The segments
    are differentiated by the customers serviced as follows:

       US-PSG

       This segment consists of sales in the United States to professional
       security dealers, distributors, installers and certain large end users of
       professional security products.

       US-DSG

       This segment sells video and security products to industrial markets and
       consumers in the United States.

       International-PSG

       This segment consists of sales to professional security dealers,
       distributors, installers and certain large end users of professional
       security products outside the United States.

       The Company's underlying accounting records are maintained on a legal
       entity basis for government and public reporting requirements. Segment
       disclosures are on a performance basis consistent with internal
       management reporting. The Company evaluates performance based on earnings
       from continuing operations before income taxes and other income and
       expense. The Corporate column includes corporate overhead related items.
       The accounting policies of the segments are the same as those described
       in the summary of significant accounting policies (Note A).

     For 1998, 1997 and 1996, 367,919, 286,655, and 10,000 stock options were
     outstanding, respectively, but not included in the computation of diluted
     income per share because the options exercise price was greater than the
     average market price of the common shares and, therefore, the effect would
     have been antidilutive.

                  (a) Borrowing Request. Borrower may request a Borrowing only
         by making or delivering a Borrowing Request (that may be telephonic if
         confirmed in writing within two Business Days) to Administrative Agent,
         which is irrevocable and binding on Borrower, stating the Type, amount
         and Interest Period for each Borrowing and which must be received by
         Administrative Agent no later than (i) 12:00 noon on the Business Day
         before the date on which funds are requested (the "BORROWING DATE") for
         any LIBOR Rate Borrowing or (ii) 12:00 noon on the Borrowing Date for
         any Base Rate Borrowing. Administrative Agent shall promptly notify
         each Lender of any Borrowing Request.




                                       15

                  (b) Funding. Each Lender shall remit its Commitment Percentage
         of each requested Borrowing to Administrative Agent's principal office
         in Dallas, Texas, in funds that are available for immediate use by
         Administrative Agent by 2:00 p.m. on the applicable Borrowing Date.
         Subject to receipt of those funds, Administrative Agent shall (unless
         to its actual knowledge any of the applicable conditions precedent have
         not been satisfied by Borrower or waived by the requisite Lenders under
         SECTION 14.10) make those funds available to Borrower by (at Borrower's
         option) (i) wiring the funds to or for the account of Borrower at the
         direction of Borrower or (ii) depositing the funds in Borrower's
         account with Administrative Agent.

                  (c) Funding Assumed. Absent contrary written notice from a
         Lender, Administrative Agent may assume that each Lender has made its
         Commitment Percentage of the requested Borrowing available to
         Administrative Agent on the applicable Borrowing Date, and
         Administrative Agent may, in reliance upon such assumption (but shall
         not be required to), make available to Borrower a corresponding amount.
         If a Lender fails to make its Commitment Percentage of any requested
         Borrowing available to Administrative Agent on the applicable Borrowing
         Date, Administrative Agent may recover the applicable amount on demand,
         (i) from that Lender together with interest, commencing on the
         Borrowing Date and ending on (but excluding) the date Administrative
         Agent recovers the amount from that Lender, at an annual interest rate
         equal to the Fed Funds Rate, or (ii) if that Lender fails to pay its
         amount upon demand, then from Borrower. No Lender is responsible for
         the failure of any other Lender to make its Commitment Percentage of
         any Borrowing; however, failure of any Lender to make its Commitment
         Percentage of any Borrowing does not excuse any other Lender from
         making its Commitment Percentage of any Borrowing.

         2.4 Letters of Credit.

                  (a) Conditions. Subject to the terms and conditions of this
         agreement and applicable Governmental Requirements, Administrative
         Agent (itself or through one of its Affiliates, and references in this
         SECTION 2.4 to "Administrative Agent" include those Affiliates) agrees,
         if requested by Borrower, to issue LCs upon Borrower's making or
         delivering an LC Request and delivering an LC Agreement, both of which
         must be received by Administrative Agent no later than the second
         Business Day before the Business Day on which the requested LC is to be
         issued, so long as (i) no LC may have an expiration date more than one
         year from its date of issuance, (ii) no LC may expire after a date 30
         Business Days before the Revolving Facility Termination Date, (iii) the
         LC Exposure does not exceed $5,000,000, and (iv) the limitations in
         SECTIONS 2.2(c), (d) and (e) are not exceeded.

                  (b) Participation. Immediately upon Administrative Agent's
         issuance of any LC, Administrative Agent shall be deemed to have sold
         and transferred to each other Lender, and each other Lender shall be
         deemed irrevocably and unconditionally to have purchased and received
         from Administrative Agent, without recourse or warranty, an undivided
         interest and participation to the extent of such Lender's Commitment
         Percentage under the Revolving Facility in the LC and all applicable
         Rights of Administrative Agent in the LC (other than Rights to receive
         certain fees provided in SECTION 4.4 to be for Administrative Agent's
         sole account).

                  (c) Reimbursement Obligation. To induce Administrative Agent
         to issue and maintain LCs, and to induce Lenders to participate in
         issued LCs, Borrower agrees to pay or reimburse Administrative Agent
         (i) on the date when any draft or draw request is presented under any
         LC, the amount paid or to be paid by Administrative Agent and (ii)
         promptly, upon demand, the amount of any additional fees Administrative
         Agent customarily charges for the application and issuance of an LC,
         for amending LC Agreements, for honoring drafts and draw requests, and
         for taking similar action in connection with letters of credit. If
         Borrower has not reimbursed Administrative Agent for any drafts or
         draws paid or to be paid by the date of Administrative Agent's demand
         for reimbursement, Administrative Agent is irrevocably authorized to
         fund Borrower's reimbursement obligations as a Base 



                                       16
<PAGE>   22

         Rate Borrowing under the Revolving Facility if proceeds are available
         under the Revolving Facility and if the conditions in this agreement
         for such a Borrowing (other than any notice requirements or minimum
         funding amounts) have, to Administrative Agent's knowledge, been
         satisfied. The proceeds of that Borrowing shall be advanced directly to
         Administrative Agent to pay Borrower's unpaid reimbursement
         obligations. If funds cannot be advanced under the Revolving Facility,
         then Borrower's reimbursement obligation shall constitute a demand
         obligation. Borrower's obligations under this section are absolute and
         unconditional under any and all circumstances and irrespective of any
         setoff, counterclaim, or defense to payment that Borrower may have at
         any time against Administrative Agent or any other Person. From
         Administrative Agent's demand for reimbursement to the date paid
         (including any payment from proceeds of a Base Rate Borrowing), unpaid
         reimbursement amounts accrue interest that is payable on demand at the
         Default Rate thereafter.

                  (d) General. Administrative Agent shall promptly notify
         Borrower of the date and amount of any draft or draw request presented
         for honor under any LC (but failure to give notice will not affect
         Borrower's obligations under this agreement). Administrative Agent
         shall pay the requested amount upon presentment of a draft or draw
         request unless presentment on its face does not comply with the terms
         of the applicable LC. When making payment, Administrative Agent may
         disregard (i) any default or potential default that exists under any
         other agreement and (ii) obligations under any other agreement that
         have or have not been performed by the beneficiary or any other Person
         (and Administrative Agent is not liable for any of those obligations).
         Borrower's reimbursement obligations to Administrative Agent and
         Lenders, and each Lender's obligations to Administrative Agent, under
         this section are absolute and unconditional irrespective of, and
         Administrative Agent is not responsible for, (i) the validity,
         enforceability, sufficiency, accuracy, or genuineness of documents or
         endorsements (even if they are in any respect invalid, unenforceable,
         insufficient, inaccurate, fraudulent, or forged), (ii) any dispute by
         any Company with or any Company's claims, setoffs, defenses,
         counterclaims, or other Rights against Administrative Agent, any
         Lender, or any other Person, or (iii) the occurrence of any Potential
         Default or Event of Default. However, nothing in this agreement
         constitutes a waiver of Borrower's Rights to assert any claim or
         defense based upon the gross negligence or willful misconduct of
         Administrative Agent or any Lender. Administrative Agent shall promptly
         distribute reimbursement payments received from Borrower to all Lenders
         according to their Pro Rata Part of the Revolving Facility.

                  (e) Obligation of Lenders. If Borrower fails to reimburse
         Administrative Agent as provided in SECTION 2.4(c) within 24 hours
         after Administrative Agent's demand for reimbursement, and funds cannot
         be advanced under the Revolving Facility to satisfy the reimbursement
         obligations, Administrative Agent shall promptly notify each Lender of
         Borrower's failure, of the date and amount paid, and of each Lender's
         Commitment Percentage of the unreimbursed amount. Each Lender shall
         promptly and unconditionally make available to Administrative Agent in
         immediately available funds its Commitment Percentage of the unpaid
         reimbursement obligation, subject to the limitations of SECTION 2.2(d).
         Funds are due and payable to Administrative Agent before the close of
         business on the Business Day when Administrative Agent gives notice to
         each Lender of Borrower's reimbursement failure (if notice is given
         before 1:00 p.m.) or on the next succeeding Business Day (if notice is
         given after 1:00 p.m.). All amounts payable by any Lender accrue
         interest after the due date at the Fed Funds Rate from the day the
         applicable draft or draw is paid by Administrative Agent to (but not
         including) the date the amount is paid by the Lender to Administrative
         Agent.

                  (f) Duties of Administrative Agent. Administrative Agent
         agrees with each Lender that it will exercise and give the same care
         and attention to each LC as it gives to its other letters of credit.
         Each Lender and Borrower agree that, in paying any draft or draw under
         any LC, Administrative Agent has no responsibility to obtain any
         document (other than any documents expressly required by the respective
         LC) or to ascertain or inquire as to any document's validity,
         enforceability, sufficiency, accuracy, or genuineness or the authority
         of any Person delivering it. Neither Administrative Agent 



                                       17
<PAGE>   23

         nor its Representatives will be liable to any Lender or any Company for
         any LC's use or for any beneficiary's acts or omissions. Any action,
         inaction, error, delay, or omission taken or suffered by Administrative
         Agent or any of its Representatives in connection with any LC,
         applicable draws, drafts or documents, or the transmission, dispatch,
         or delivery of any related message or advice, if in good faith and in
         conformity with applicable Governmental Requirements and in accordance
         with the standards of care specified in the Uniform Customs and
         Practices for Documentary Credits (1993 Revision), International
         Chamber of Commerce Publication No. 500 (as amended or modified), is
         binding upon the Companies and Lenders and does not place
         Administrative Agent or any of its Representatives under any resulting
         liability to any Company or any Lender. Administrative Agent is not
         liable to any Company or any Lender for any action taken or omitted, in
         the absence of gross negligence or willful misconduct, by
         Administrative Agent or its Representatives in connection with any LC.

                  (g) Cash Collateral. On the Revolving Facility Termination
         Date, and if requested by Required Lenders while an Event of Default
         exists, Borrower shall provide Administrative Agent, for the benefit of
         Lenders, cash collateral in an amount to equal the then-existing LC
         Exposure.

                  (h) INDEMNIFICATION. BORROWER SHALL PROTECT, INDEMNIFY, PAY,
         AND SAVE ADMINISTRATIVE AGENT, EACH LENDER, AND THEIR RESPECTIVE
         REPRESENTATIVES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS,
         LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES, AND EXPENSES (INCLUDING
         REASONABLE ATTORNEYS' FEES) WHICH ANY OF THEM MAY INCUR OR BE SUBJECT
         TO AS A CONSEQUENCE OF THE ISSUANCE OF ANY LC, ANY DISPUTE ABOUT IT, OR
         THE FAILURE OF ADMINISTRATIVE AGENT TO HONOR A DRAFT OR DRAW REQUEST
         UNDER ANY LC AS A RESULT OF ANY ACT OR OMISSION (WHETHER RIGHT OR
         WRONG) OF ANY PRESENT OR FUTURE GOVERNMENTAL AUTHORITY. HOWEVER, NO
         PERSON IS ENTITLED TO INDEMNITY UNDER THE FOREGOING FOR ITS OWN GROSS
         NEGLIGENCE OR WILLFUL MISCONDUCT.

                  (i) LC Agreements. Although referenced in any LC, terms of any
         particular agreement or other obligation to the beneficiary are not
         incorporated into this agreement in any manner. The fees and other
         amounts payable with respect to each LC are as provided in this
         agreement, drafts and draws under each LC are part of the Obligation,
         only the events specified in this agreement as an Event of Default
         shall constitute a default under any LC, and the terms of this
         agreement control any conflict between the terms of this agreement and
         any LC Agreement.

         2.5 Borrowing Requests and LC Requests. Each Borrowing Request and LC
Request constitutes a representation and warranty by Borrower that as of the
Borrowing Date or the date of issuance of the requested LC, as the case may be,
that all of the conditions precedent in SECTION 6 have been satisfied.

         2.6 Termination. Upon giving at least five Business Days prior written
and irrevocable notice to Administrative Agent, Borrower may terminate all or
part of the unused portion of the Revolving Facility. Each partial termination
must be in an amount of not less than $1,000,000 or a greater integral multiple
of $1,000,000, and must be ratable in accordance with each Lender's Commitment
Percentage. At the time of any termination, Borrower shall pay to Administrative
Agent, for the account of each Lender, as applicable, all accrued and unpaid
fees under this agreement, the interest attributable to the amount of that
reduction, and any related Funding Loss. Any part of the Commitment for the
Revolving Facility that is terminated may not be reinstated.

SECTION 3. TERMS OF PAYMENT.

         3.1 Notes and Payments.

                  (a) Notes. The Term Loan is evidenced by the Term Notes, one
         payable to each Lender in the stated amount of its Commitment for the
         Term Loan. Principal Debt under the Revolving Facility is evidenced by
         the Revolving Notes, one payable to each Lender in the stated amount of
         its Commitment for the Revolving Facility.

                  (b) Payment. Borrower must make each payment and prepayment on
         the Obligation to Administrative Agent's principal office in Dallas,
         Texas in immediately available funds by 1:00 p.m. on the day due;
         otherwise, but subject to SECTION 3.8, those funds continue to accrue
         interest as if they were received on the next Business Day.
         Administrative Agent shall promptly pay to each Lender the part of any
         payment or prepayment to which that Lender is entitled under this
         agreement on the same day Administrative Agent receives the funds from
         Borrower.

                  (c) Payment Assumed. Unless Administrative Agent has received
         notice from Borrower prior to the date on which any payment is due
         under this agreement that Borrower will not make that payment in full,
         Administrative Agent may assume that Borrower has made the full payment
         due and Administrative Agent may, in reliance upon that assumption,
         cause to be distributed to each Lender on that date the amount then due
         to each Lender. If and to the extent Borrower does not make the full
         payment due to Administrative Agent, each Lender shall repay to
         Administrative Agent on demand the amount distributed to that Lender by
         Administrative Agent together with interest for each day from the date
         that Lender received payment from Administrative Agent until the date
         that Lender repays Administrative Agent (unless such repayment is made
         on the same day as such distribution), at an interest rate equal to the
         Fed Funds Rate.

         3.2 Interest and Principal Payments.

                  (a) Interest. Accrued interest on each LIBOR Rate Borrowing is
         due and payable on the 15th day of each January, April, July and
         October, commencing on the first of those dates that follows the
         Closing Date, and on the last day of its respective Interest Period.
         Accrued interest on each Base Rate Borrowing is due and payable on the
         15th day of each January, April, July and October, commencing on the
         first of those dates that follows the Closing Date. Accrued interest is
         also due and payable (irrespective of the Type of Borrowing) (i) on the
         Revolving Facility Termination Date in respect of accrued interest on
         the Revolving Facility, and (ii) on the final maturity date of the Term
         Loan as set forth in CLAUSE (d) below in respect of accrued interest on
         the Term Loan.

                  (b) Revolving Facility Principal. The Principal Debt under the
         Revolving Facility is due and payable on the Revolving Facility
         Termination Date. Before that date, Borrower may at any time prepay,
         without penalty (except as provided in this agreement) and in whole or
         in part, the Principal Debt under the Revolving Facility, so long as
         (i) each voluntary partial prepayment must be in a principal amount not
         less than $1,000,000, or a greater integral multiple of $1,000,000 and
         (ii) Borrower shall pay any related Funding Loss upon demand.
         Conversions under SECTION 3.10 are not prepayments.



                                       19
<PAGE>   25


                  (c) Revolving Facility Mandatory Prepayments. Immediately upon
         a Permitted Asset Sale as described in CLAUSE (v) or (vi) of the
         definition of "Permitted Asset Sale," Borrower shall make a mandatory
         prepayment to Administrative Agent (with any related Funding Loss)
         under the Revolving Facility in an amount equal to 80% of the Net
         Proceeds of such Permitted Asset Sale, but only to the extent Borrower
         is not able to use such proceeds to prepay the Term Loan as required by
         CLAUSE (f)(i) below.

                  (d) Term Loan Principal. The Principal Debt under the Term
         Loan is due and payable in installments of $833,333.33 on the 15th day
         of each January, April, July and October, commencing April 15, 2000,
         and ending on January 15, 2002, the a final payment of all remaining
         Principal Debt under the Term Loan being due and payable on February
         16, 2002.

                  (e) Term Loan Voluntary Prepayments. Borrower may, by giving
         notice to Administrative Agent no later than five Business Days before
         the date of the prepayment, prepay, without penalty (except as provided
         in this agreement) and in whole or part, the Principal Debt under the
         Term Loan, so long as (i) the notice by Borrower specifies the amount
         to be prepaid, (ii) each voluntary partial prepayment must be in a
         principal amount of not less than $1,000,000, or a greater integral
         multiple of $1,000,000, plus accrued interest on the amount prepaid to
         the date of the prepayment and (iii) Borrower shall pay any related
         Funding Loss upon demand. Conversions under SECTION 3.10 are not
         prepayments. No voluntary prepayment of the Term Loan may be
         reborrowed. Voluntary prepayments of the Term Loan shall be applied to
         installments in order of maturity.

                  (f) Term Loan Mandatory Prepayments.

                           (i) Immediately upon a Permitted Asset Sale as
                  described in CLAUSE (v) or (vi) of the definition of
                  "Permitted Asset Sale," Borrower shall make a mandatory
                  prepayment to Administrative Agent (with any related Funding
                  Loss) on the Term Loan in an amount equal to 80% of the Net
                  Proceeds of such Permitted Asset Sale. No such mandatory
                  prepayment of the Term Loan may be reborrowed.

                           (ii) All prepayments under this CLAUSE (f) shall be
                  applied to installments in inverse order of maturity.

         3.3 Interest Options. Except that the LIBOR Rate may not be selected
when an Event of Default of Potential Default exists, and except as otherwise
provided in this agreement, Borrowings bear interest at an annual rate equal to
the lesser of (i) the Base Rate plus the Applicable Margin or the LIBOR Rate
plus the Applicable Margin (in each case as designated or deemed designated by
Borrower), as the case may be and (ii) the Maximum Rate. Each change in the Base
Rate, LIBOR Rate or Maximum Rate is effective, without notice to Borrower or any
other Person, upon the effective date of change.

         3.4 Quotation of Rates. Borrower may call Administrative Agent before
delivering a Borrowing Request to receive an indication of the interest rates
then in effect, but the indicated rates do not bind Administrative Agent or
Lenders or affect the interest rate that is actually in effect when Borrower
makes a Borrowing Request or on the Borrowing Date.

         3.5 Default Rate. All past-due Principal Debt and, unless prohibited by
applicable Government Requirements, past-due interest accruing on the Principal
Debt shall, at Administrative Agent's option, bear interest on the amount
thereof from time to time outstanding from the date due (stated or by
acceleration) at the Default Rate until paid, regardless whether payment is made
before or after entry of a judgment.

         3.6 Interest Recapture. If the designated interest rate applicable to
any Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent 



                                       20
<PAGE>   26

reductions in the designated rate shall not reduce the interest rate thereon
below the Maximum Rate until the total amount of accrued interest equals the
amount of interest that would have accrued if that designated rate had always
been in effect. If at maturity (stated or by acceleration), or at final payment
of the Notes, the total interest paid or accrued is less than the interest that
would have accrued if the designated rates had always been in effect, then, at
that time and to the extent not prohibited by applicable Governmental
Requirements, Borrower shall pay an amount equal to the difference between (a)
the lesser of the amount of interest that would have accrued if the designated
rates had always been in effect and the amount of interest that would have
accrued if the Maximum Rate had always been in effect, and (b) the amount of
interest actually paid or accrued on the Notes.

         3.7 Interest Calculations. Interest on all LIBOR Rate Borrowings will
be calculated on the basis of a 360-day year consisting of twelve 30-day months
(including the first day but excluding the last day). Interest on all Base Rate
Borrowings will be calculated on the basis of a year consisting of 365 or 366
days, as the case may be (including the first day but excluding the last day).
All interest rate determinations and calculations by Administrative Agent are
conclusive and binding absent manifest error.

         3.8 Maximum Rate. It is the intent of Administrative Agent, Lenders and
Borrower in the execution and performance of the Credit Documents to remain in
strict compliance with applicable Governmental Requirements from time to time in
effect, including applicable laws limiting the amount or rate of interest.
Administrative Agent, Lenders and Borrower stipulate and agree that none of the
terms and provisions contained in the Credit Documents shall ever be construed
to create a contract to pay for the use, forbearance or detention of money with
interest at a rate or in an amount in excess of the Maximum Rate or Maximum
Amount. For purposes of the Credit Documents, "interest" shall include the
aggregate of all charges which constitute interest under applicable Governmental
Requirements that are contracted for, charged, reserved, received or paid under
the Credit Documents. Borrower shall never be required to pay unearned interest
and shall never be required to pay interest at a rate or in an amount in excess
of the Maximum Rate or Maximum Amount, and the provisions of this section shall
control over all other provisions of the Credit Documents, and of any other
instrument pertaining to or securing the Obligation, which may be in actual or
apparent conflict herewith. If the Obligation is prepaid, or if the maturity of
the Obligation is accelerated for any reason, or if under any contingency the
effective rate or amount of interest which would otherwise be payable under the
Credit Documents would exceed the Maximum Rate or Maximum Amount, or in the
event any Lender or any holder of the Notes shall charge, contract for, take,
reserve or receive monies that are deemed to constitute interest which would, in
the absence of this provision, increase the effective rate or amount of interest
payable under the Credit Documents to a rate or amount in excess of that
permitted to be charged, contracted for, taken, reserved or received under
applicable Governmental Requirements then in effect, then the principal amount
of the Obligation or the amount of interest which would otherwise be payable
under the Notes or both shall be reduced to the amount allowed under applicable
Governmental Requirements as now or hereinafter construed by the courts having
jurisdiction, and all such moneys so charged, contracted for, taken, reserved or
received that are deemed to constitute interest in excess of the Maximum Rate
shall immediately be returned to or credited to the account of Borrower upon
such determination. Administrative Agent, Lenders and Borrower further stipulate
and agree that, without limitation of the foregoing, all calculations of the
rate or amount of interest contracted for, charged, taken, reserved or received
under the Credit Documents which are made for the purpose of determining whether
such rate or amount exceeds the Maximum Rate or Maximum Amount, shall be made to
the extent not prohibited by applicable Governmental Requirements, by
amortizing, prorating, allocating and spreading during the period of the full
stated term of the Notes, all interest at any time contracted for, charged,
taken, reserved or received from Borrower or otherwise by Lenders or any other
holder of the Notes. If the Governmental Requirements of the State of Texas are
applicable for purposes of determining the "Maximum Rate" or the "Maximum
Amount," then those terms mean the indicated rate ceiling from time to time in
effect under Chapter 1D, Subtitle 1, Title 79, Revised Civil Statutes of Texas,
as amended.

         3.9 Interest Periods. When Borrower requests any LIBOR Rate Borrowing,
Borrower may elect the applicable interest period (each an "INTEREST PERIOD"),
which may be, at Borrower's option, one, three


                                       21
<PAGE>   27

or six months, subject to the following conditions: (i) the initial Interest
Period for a LIBOR Rate Borrowing commences on the applicable Borrowing Date or
conversion date, and each subsequent Interest Period applicable to any Borrowing
commences on the day when the next preceding applicable Interest Period expires;
(ii) if any Interest Period for a LIBOR Rate Borrowing begins on a day for which
no numerically corresponding Business Day in the calendar month at the end of
the Interest Period exists, then the Interest Period ends on the last Business
Day of that calendar month; (iii) if Borrower is required to pay any portion of
a LIBOR Rate Borrowing before the end of its Interest Period in order to comply
with the payment provisions of the Credit Documents, Borrower shall also pay any
related Funding Loss; (iv) no Interest Period for any portion of Principal Debt
may extend beyond the scheduled repayment date for that portion of Principal
Debt; and (v) no more than six Interest Periods may be in effect at one time.

         3.10 Conversions. Subject to the dollar limits of SECTION 2.2(B) and
provided that Borrower may not convert to or select a new Interest Period for a
LIBOR Rate Borrowing at any time when an Event of Default exists, Borrower may
(i) convert a LIBOR Rate Borrowing on the last day of the applicable Interest
Period to a Base Rate Borrowing, (ii) convert a Base Rate Borrowing at any time
to a LIBOR Rate Borrowing and (iii) elect a new Interest Period for a LIBOR Rate
Borrowing. That election may be made by telephonic request to Administrative
Agent no later than 12:00 noon on the Business Day before the conversion date or
the last day of the Interest Period, as the case may be (for conversion to a
LIBOR Rate Borrowing or election of a new Interest Period), and no later than
12:00 noon on the last day of the Interest Period (for conversion to a Base Rate
Borrowing). Borrower shall provide a Conversion Notice to Administrative Agent
no later than three days after the date of the conversion or election. Absent
Borrower's telephonic request for conversion or election of a new Interest
Period or if an Event of Default exists, then, a LIBOR Rate Borrowing shall be
deemed converted to a Base Rate Borrowing effective when the applicable Interest
Period expires.

         3.11 Order of Application.

                  (a) No Event of Default. If no Event of Default exists, any
         payment shall be applied to the Obligation in the order and manner as
         Borrower directs except as otherwise specifically provided in the
         Credit Documents.

                  (b) Event of Default or No Direction. If an Event of Default
         exists, or if Borrower fails timely to give direction, any payment
         (including proceeds from the exercise of any Rights) shall be applied
         in the following order: (i) To all fees and expenses for which
         Administrative Agent or Lenders have not been paid or reimbursed in
         accordance with the Credit Documents (and if such payment is less than
         all unpaid or unreimbursed fees and expenses, then the payment shall be
         paid against unpaid and unreimbursed fees and expenses in the order of
         incurrence or due date); (ii) to accrued interest on the Principal
         Debt; (iii) to any LC reimbursement obligations that are due and
         payable and that remain unfunded by any Borrowing under the Revolving
         Facility; (iv) to the remaining Principal Debt in the order as Required
         Lenders may elect (but Required Lenders agree to apply proceeds in an
         order that will minimize any Funding Loss); (v) to the remaining
         Obligation in the order and manner Required Lenders deem appropriate;
         (vi) as a deposit with Administrative Agent, for the benefit of
         Lenders, as security for and payment of any subsequent LC reimbursement
         obligations.

                  (c) Pro Rata. Each payment or prepayment shall be distributed
         to each Lender in accordance with its Pro Rata Part of that payment or
         prepayment

         3.12 Sharing of Payments, Etc. If any Lender obtains any payment or
prepayment with respect to the Obligation (whether voluntary, involuntary, or
otherwise, including, without limitation, as a result of exercising its Rights
under SECTION 3.13) that exceeds the part of that payment or prepayment that it
is then entitled to receive under the Credit Documents, then that Lender shall
purchase from the other Lenders participations that will cause the purchasing
Lender to share the excess payment or prepayment ratably with each other Lender.
If all or any portion of any excess payment or prepayment is subsequently
recovered from 



                                       22
<PAGE>   28


the purchasing Lender, then the purchase shall be rescinded and the purchase
price restored to the extent of the recovery. Borrower agrees that any Lender
purchasing a participation from another Lender under this section may, to the
fullest extent permitted by applicable Governmental Requirements, exercise all
of its Rights of payment (including the Right of offset) with respect to that
participation as fully as if that Lender were the direct creditor of Borrower in
the amount of that participation.

         3.13 Offset. If an Event of Default exists, to the extent not
prohibited by applicable Governmental Requirements, each Lender may exercise
(for the benefit of all Lenders in accordance with SECTION 3.12) the Rights of
offset and banker's Lien against each and every account and other property, or
any interest therein, that any Company may now or hereafter have with, or which
is now or hereafter in the possession of, that Lender to the extent of the full
amount of the Obligation owed (directly or participated) to it.

         3.14 Booking Borrowings. To the extent permitted by applicable
Governmental Requirements, any Lender may make, carry, or transfer its
Borrowings at, to, or for the account of any of its branch offices or the office
or branch of any of its Affiliates. However, no Affiliate or branch is entitled
to receive any greater payment under SECTION 3.16 than the transferor Lender
would have been entitled to receive with respect to those Borrowings, and a
transfer may not be made if, as a direct result of it, SECTION 3.15 or 3.17
would apply to any of the Obligation. If any of the conditions of SECTIONS 3.16
or 3.17 ever apply to a Lender, that Lender shall, to the extent possible, carry
or transfer its Borrowings at, to, or for the account of any of its branch
offices or the office or branch of any of its Affiliates so long as the transfer
is consistent with the other provisions of this section, does not create any
burden or adverse circumstance for that Lender that would not otherwise exist,
and eliminates or ameliorates the conditions of SECTIONS 3.16 or 3.17, as
applicable.

         3.15 Basis Unavailable or Inadequate for LIBOR Rate. If on or before
any date when a LIBOR Rate is to be determined for a Borrowing, Administrative
Agent or any Lender determines (and Required Lenders agree with that
determination) that the basis for determining the applicable rate is not
available or that the resulting rate does not accurately reflect the cost to
Lenders of making or converting Borrowings at that rate for the applicable
Interest Period, then Administrative Agent shall promptly notify Borrower and
Lenders of that determination (which is conclusive and binding on Borrower
absent manifest error), and the applicable Borrowing shall bear interest at the
sum of the Base Rate plus the Applicable Margin. Until Administrative Agent
notifies Borrower that those circumstances giving rise to such notice no longer
exist, Lenders' commitments under this agreement to make, or to convert to,
LIBOR Rate Borrowings, as the case may be, shall be suspended.

         3.16 Additional Costs. Each Lender severally and not jointly agrees to
notify Administrative Agent, the other Lenders, and Borrower within 180 days
after it has actual knowledge that any circumstances exist that would give rise
to any payment obligation by Borrower under CLAUSES (A) through (C) below.
Although no Lender shall have any liability to Administrative Agent, any other
Lender, or any Company for its failure to give that notice, Borrower is not
obligated to pay any amounts under those clauses that arise, accrue or are
imposed more than 180 days before that notice to the extent it is applicable to
those amounts. To demand payment under this section, any such Lender must
generally be making similar demand for similar additional costs under credit
agreements to which it is party that contain similar provisions to this section.

                  (a) Reserves. With respect to any LIBOR Rate Borrowing (i) if
         any change in any present Governmental Requirement, any change in the
         interpretation or application of any present Governmental Requirement,
         or any future Governmental Requirement imposes, modifies or deems
         applicable (or if compliance by any Lender with any requirement of any
         Governmental Authority results in) any requirement that any reserves
         (including, without limitation, any marginal, emergency, supplemental,
         or special reserves) be maintained (other than any reserve included in
         the Reserve Requirement) and if (ii) those reserves reduce any sums
         receivable by that Lender under this agreement or increase the costs
         incurred by Lender in advancing or maintaining any portion of any LIBOR
         Rate Borrowing, then (iii) that Lender (through Administrative Agent)
         shall deliver to Borrower a certificate



                                       23
<PAGE>   29




         setting forth in reasonable detail the calculation of the amount
         necessary to compensate it for its reduction or increase (which
         certificate is conclusive and binding absent manifest error), and (iv)
         Borrower shall pay that amount to that Lender within ten Business Days
         after demand. The provisions of and undertakings and indemnifications
         in this CLAUSE (A) survive the satisfaction and payment of the
         Obligation and termination of this agreement.

                  (b) Capital Adequacy. With respect to any Borrowing or LC, if
         any change in any present Governmental Requirement, any change in the
         interpretation or application of any present Governmental Requirement,
         or any future Governmental Requirement regarding capital adequacy, or
         if compliance by Administrative Agent (as issuer of LCs) or any Lender
         with any request, directive or requirement imposed in the future by any
         Governmental Authority regarding capital adequacy, or if any change in
         its written policies or in the risk category of this transaction, in
         any of the foregoing events or circumstances, reduces the rate of
         return on its capital as a consequence of its obligations under this
         agreement to a level below that which it otherwise could have achieved
         (taking into consideration its policies with respect to capital
         adequacy) by an amount deemed by it to be material (and it may, in
         determining the amount, utilize reasonable assumptions and allocations
         of costs and expenses and use any reasonable averaging or attribution
         method), then (unless the effect is already reflected in the rate of
         interest then applicable under this agreement) Administrative Agent or
         that Lender (through Administrative Agent) shall notify Borrower and
         deliver to Borrower a certificate setting forth in reasonable detail
         the calculation of the amount necessary to compensate it (which
         certificate is conclusive and binding absent manifest error), and
         Borrower shall pay that amount to Administrative Agent or that Lender
         within ten Business Days after demand. The provisions of and
         undertakings and indemnification in this CLAUSE (b) shall survive the
         satisfaction and payment of the Obligation and termination of this
         agreement.

                  (c) Taxes. Any Taxes payable by Administrative Agent or any
         Lender or ruled by a Governmental Authority to be payable by
         Administrative Agent or any Lender in respect of this agreement or any
         other Credit Document shall, if permitted by applicable Governmental
         Requirements, be paid by Borrower, together with interest and
         penalties, if any, except for Taxes payable on or measured by the
         overall net income of Administrative Agent or that Lender (or any other
         Person with whom Administrative Agent or that Lender files a
         consolidated, combined, unitary, or similar Tax return) and except for
         interest and penalties incurred as a result of the gross negligence or
         willful misconduct of Administrative Agent or that Lender.
         Administrative Agent or that Lender (through Administrative Agent)
         shall notify Borrower and deliver to Borrower a certificate setting
         forth in reasonable detail the calculation of the amount of Taxes
         payable, which certificate is conclusive and binding (absent manifest
         error), and Borrower shall pay that amount to Administrative Agent for
         its account or the account of that Lender, as the case may be, within
         ten Business Days after demand. If Administrative Agent or that Lender
         subsequently receives a refund of the Taxes paid to it by Borrower,
         then the recipient shall promptly pay the refund to Borrower.

         3.17 Change in Governmental Requirements. If any Governmental
Requirement makes it unlawful for any Lender to make or maintain LIBOR Rate
Borrowings, then that Lender shall promptly notify Borrower and Administrative
Agent, and (i) as to undisbursed funds, that requested Borrowing shall be made
as a Base Rate Borrowing and (ii) as to any outstanding Borrowing (a) if
maintaining the Borrowing until the last day of the applicable Interest Period
is unlawful, the Borrowing shall be converted to a Base Rate Borrowing as of the
date of notice, in which event Borrower will not be required to pay any related
Funding Loss or (b) if not prohibited by applicable Governmental Requirements,
the Borrowing shall be converted to a Base Rate Borrowing as of the last day of
the applicable Interest Period or (c) if any conversion will not resolve the
unlawfulness, Borrower shall promptly prepay the Borrowing, without penalty but
with related Funding Loss.

         3.18 Funding Loss. BORROWER SHALL INDEMNIFY EACH LENDER AGAINST, AND
PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF THAT LENDER. WHEN ANY LENDER DEMANDS
THAT BORROWER PAY ANY



                                       24
<PAGE>   30

FUNDING LOSS, THAT LENDER SHALL DELIVER TO BORROWER AND ADMINISTRATIVE AGENT A
CERTIFICATE SETTING FORTH IN REASONABLE DETAIL THE BASIS FOR IMPOSING FUNDING
LOSS AND THE CALCULATION OF THE AMOUNT, WHICH CALCULATION IS CONCLUSIVE AND
BINDING ABSENT MANIFEST ERROR. THE PROVISIONS OF AND UNDERTAKINGS AND
INDEMNIFICATION IN THIS SECTION SURVIVE THE SATISFACTION AND PAYMENT OF THE
OBLIGATION AND TERMINATION OF THIS AGREEMENT.

         3.19 Foreign Lenders, Participants, and Assignees. Each Lender,
Participant (by accepting a participation interest under this agreement), and
Assignee (by executing an Assignment) that is not organized under the
Governmental Requirements of the United States of America or one of its states
(a) represents to Administrative Agent and Borrower that (i) no Taxes are
required to be withheld by Administrative Agent or Borrower with respect to any
payments to be made to it in respect of the Obligation and (ii) it has furnished
to Administrative Agent and Borrower two duly completed copies of either U.S.
Internal Revenue Service Form 4224, Form 1001, Form W-8, or any other form
acceptable to Administrative Agent and Borrower that entitles it to a complete
exemption from U.S. federal withholding Tax on all interest or fee payments
under the Credit Documents, and (b) covenants to (i) provide Administrative
Agent and Borrower a new Form 4224, Form 1001, Form W-8, or other form
acceptable to Administrative Agent and Borrower upon the expiration or
obsolescence according to applicable Governmental Requirements of any previously
delivered form, duly executed and completed by it, entitling it to a complete
exemption from U.S. federal withholding Tax on all interest and fee payments
under the Credit Documents, and (ii) comply from time to time with all
applicable Governmental Requirements with regard to the withholding Tax
exemption. If any of the foregoing is not true at any time or the applicable
forms are not provided, then Borrower and Administrative Agent (without
duplication) may deduct and withhold from interest and fee payments under the
Credit Documents any Tax at the maximum rate under the IRC or other applicable
Governmental Requirement, and amounts so deducted and withheld shall be treated
as paid to that Lender, Participant, or assignee, as the case may be, for all
purposes under the Credit Documents.

SECTION 4. FEES.

         4.1 Treatment of Fees. The fees described in this SECTION 4 (i) are not
compensation for the use, detention or forbearance of money, (ii) are in
addition to, and not in lieu of, interest and expenses otherwise described in
the Credit Documents, (iii) are payable in accordance with SECTION 3.1, (iv) are
non-refundable, (v) to the fullest extent not prohibited by applicable
Governmental Requirements, bear interest, if not paid when due, on the amount
thereof from time to time unpaid at the Default Rate and (vi) with respect to
the fees referenced in SECTIONS 4.3 and 4.4, are calculated on the basis of the
actual number of days (including the first day but excluding the last day)
elapsed, as if each calendar year consisted of 360 days, unless such amount is
determined to constitute interest and if so, such computation would result in an
interest rate deemed to exceed (notwithstanding the foregoing) the Maximum Rate
in which event the computation is made on the basis of a year of 365 or 366
days, as the case may be.

         4.2 Arrangement and Underwriting Fees. Borrower shall pay to
Administrative Agent arrangement, structure, management, documentation, due
diligence and custodial fees in amounts and upon such payment terms as may be
separately agreed upon by Borrower and Administrative Agent in writing.

         4.3 Unused Facility Fee. From and after the Closing Date, Borrower
shall pay to Administrative Agent for the account of each Lender, according to
each Lender's Commitment Percentage on the day the fee is payable, an unused
facility fee for the Revolving Facility. The fee accrues on the last day of each
December, March, June and September, and is due and payable on the 15th day of
each January, April, July and October, commencing on April 15, 1999, and on the
Revolving Facility Termination Date. Each payment of the fee is equal to the
following, determined for the calendar quarter (or portion of a calendar quarter
commencing on the Closing Date or ending on the Revolving Facility Termination
Date) preceding and including the date it accrues: From the Closing Date until
the Revolving Facility Termination Date, the product of (i) the Applicable
Percentage times (ii) the amount by which the average-daily total Commitment for
only the Revolving Facility



                                       25
<PAGE>   31

exceeds the sum of the average-daily Principal Debt under only the Revolving
Facility plus the average-daily LC Exposure for standby LCs, times (iii) a
fraction with the number of days in the applicable quarter or portion of it as
the numerator and 365 as the denominator.

         4.4 LC Fees. As a condition precedent to the issuance (including,
without limitation, the extension) of each LC, Borrower shall pay to
Administrative Agent:

                  (a) For the account of each Lender, according to each Lender's
         Commitment Percentage on the day the fee is payable, an issuance fee,
         payable quarterly in arrears, equal to a percentage of the average-face
         amount of that LC during each applicable quarterly period, which
         percentage is equal to the Applicable Margin in effect for LIBOR Rate
         Borrowings on the first day of the quarterly period for which a payment
         is payable; and

                  (b) For the account of Administrative Agent, payable on the
         date of issuance, a fronting fee of the greater of (A) $300 or (B)
         0.125% of the face amount of each standby LC.

         4.5 Prepayment Fee. If the Obligation is entirely prepaid at any time
prior to February 16, 2000, Borrower shall pay to Administrative Agent for the
account of each Lender, according to each Lender's Commitment Percentage on the
day the fee is payable, a prepayment fee equal to 0.250% multiplied by the total
Commitments of all Lenders as of the Closing Date. Notwithstanding the
foregoing, no prepayment fee will be assessed against Borrower if the Obligation
is prepaid solely from the proceeds of an underwritten public offering of
Borrower's stock or debt securities, or from the proceeds of an acquisition of
Borrower by an unrelated third party.

SECTION 5. SECURITY.

         5.1 Guaranty. Borrower shall cause each of its present and future
Subsidiaries to (a) unconditionally guarantee the full payment and performance
of the Obligation by execution of a Guaranty (other than any Foreign Subsidiary
the execution of a Guaranty by which would create a material Tax obligation for
the Companies that would not otherwise exist) and (b) grant liens in all
Collateral now or hereafter owned by any of the, by due execution and delivery
of a Security Agreement to Administrative Agent for Lenders.

         5.2 Collateral. Borrower shall cause full payment and performance of
the Obligation to be secured by Lender Liens on all of the items and types of
property (together with its proceeds, the "COLLATERAL"), described in the
present and future Credit Documents creating Lender Liens, including, without
limitation:

                  (a) Present and future accounts receivable, inventory, general
         intangibles, contract rights, equipment, fixtures, patents, trademarks,
         other intellectual property and all other personal property of each
         present and future Domestic Company;

                  (b) 100% of the present and future issued and outstanding
         capital stock, partnership interests, and other equity interests of all
         of Borrower's present and future Domestic Subsidiaries;



                                       26
<PAGE>   32


                  (c) Approximately all (but not less than 65%) of the present
         and future issued and outstanding capital stock, partnership interests,
         and other equity interests of all of Borrower's present and future
         Foreign Subsidiaries the pledge of which would not create a material
         Tax obligation for the Companies that would not otherwise exist; and

                  (d) All present and future notes receivable executed by a
         Foreign Subsidiary in favor of Borrower.

         5.3 Creation of Liens and Further Assurances. Borrower covenants and
agrees that the Lender Liens described in SECTION 5.2 shall be created and
perfected as a condition to funding any Borrowings or the issuance of any LC.
Furthermore, Borrower shall, and shall cause each other appropriate Company to,
perform the acts, duly authorize, execute, acknowledge, deliver, file, and
record any additional writings, and pay all filing fees and costs as
Administrative Agent or Required Lenders may reasonably deem appropriate or
necessary to perfect and maintain the Lender Liens and preserve and protect the
Rights of Administrative Agent and Lenders under any Credit Document.

         5.4 Change in Tax Laws. Notwithstanding anything to the contrary set
forth in this SECTION 5, in the event the Tax laws regarding Foreign
Subsidiaries are changed to remove the creation of a material Tax obligation for
the Companies, each such Foreign Subsidiary may, at Borrower's discretion,
execute a Guaranty in exchange for a release of the pledge of its securities.

         5.5 Release of Collateral. Whenever Lenders no longer have any
commitment to extend credit under any Credit Document and the Obligation has
been fully paid and performed, then Administrative Agent and Lenders shall, upon
Borrower's written request and at Borrower's cost and expense, cause the Lender
Liens on all Collateral to be released and all Guaranties to be terminated and
released.

SECTION 6. CONDITIONS PRECEDENT.

         6.1 Initial Advances. The obligation of Lenders to make the initial
advances under this agreement is subject to the condition precedent that, on or
before the date of such advance, Administrative Agent and Lenders have received,
there shall have been performed and there shall exist, the documents, actions
and other matters set forth below, each in form, scope and substance, and (as
applicable) dated as of a date, satisfactory to Administrative Agent and

SECTION 7. REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants to
Administrative Agent and Lenders as follows:

         7.1 Purpose and Regulation U.

                  (a) Subject to the other provisions in the Credit Documents,
         including, without limitation, CLAUSE (b) below, the proceeds of the
         Term Loan will be used to refinance the term loan portion of the
         Refinanced Debt and for general corporate purposes, and the proceeds of
         the Revolving Facility will be used to refinance the revolving loan
         portion of the Refinanced Debt, for general corporate purposes, working
         capital uses in the ordinary course of business, Permitted
         Acquisitions, and permitted stock repurchases.

                  (b) The proceeds of the Revolving Facility and Term Loan will
         be used by Borrower solely for the purposes specified in SECTION
         7.1(a). None of such proceeds will be used for the purpose of
         purchasing or carrying any "margin stock"as defined in Regulation U or
         G of the Board of Governors of the Federal Reserve System (12 C.F.R.
         Part 221 and 207), or for the purpose of reducing or retiring any
         indebtedness which was originally incurred to purchase or carry a
         margin stock or for any other purpose which might constitute this
         transaction a "purpose credit" within the meaning of such Regulation U
         or G. No Company is engaged in the business of extending credit for the
         purpose of purchasing or carrying margin stocks. No Company, nor any
         Person acting on behalf of any Company, has taken or will take any
         action that might cause the Notes or any other of the Credit Documents,
         including this Credit Agreement, to violate Regulations U or G or any
         other regulations of the Board of Governors of the Federal Reserve
         System or to violate Section 7 of the Securities Exchange Act of 1934
         or any rule or regulation thereunder, in each case as now in effect or
         as the same may hereinafter be in effect. For the avoidance of doubt,
         no proceeds of the Revolving Facility or Term Loan may be used to
         purchase any securities, including without limitation, any of the
         Permitted Investments described in CLAUSES (f) through (h) of SECTION
         9.7.

         7.2 Corporate Existence, Good Standing, Authority and Locations. Each
Company is duly organized, validly existing and in good standing under the
Governmental Requirements of its jurisdiction of incorporation or formation, as
applicable. Except where the failure to qualify would not result in a Material
Adverse Event, each Company is duly qualified to transact business and is in
good standing as a foreign corporation or partnership (as applicable) in each
jurisdiction where the nature and extent of its business and



                                       30
<PAGE>   36


properties require due qualification and good standing (and each of such
jurisdictions is identified in SCHEDULE 7.3). Each Company possesses all
requisite authority and power to conduct its business as is now being conducted
and as proposed to be conducted (including under the Credit Documents) and to
own and operate its assets as now owned and operated and as proposed to be owned
and operated (including under the Credit Documents). Each Company's chief

present location of each Company's books and records concerning accounts and
accounts receivable is at its chief executive office.

         7.3 Subsidiaries and Names. SCHEDULE 7.3 describes (i) each Company,

shares of capital stock (or similar voting interests) of each Company are (1)

record and beneficially as described in SCHEDULE 7.3, free and clear of any

evidencing such shares.

         7.4 Authorization and Contravention. The execution and delivery by each
Company of each Credit Document to which it is a party and the performance by it
of its obligations under those Credit Documents (i) are within its corporate or
partnership power (as applicable), (ii) have been duly authorized by all
necessary corporate or partnership action (as applicable), (iii) require no

Agent for Lenders.

         7.5 Binding Effect. Upon execution by each Company of each Credit
Document to which it is a party, each such Credit Document will constitute a
legal and binding obligation of each such party, enforceable against each such
party in accordance with that Credit Document's terms except as that
enforceability may be limited by Debtor Relief Laws and general principles of
equity.

         7.6 Financials. The Current Financials were prepared in accordance with
GAAP and present fairly, in all material respects, the Companies' consolidated
(if applicable) financial condition, results of operations and cash flows as of,
and for the portion of the fiscal year ending on, their dates (subject only to
normal year-end adjustments for interim statements). Except for transactions
directly related to, or specifically contemplated or expressly permitted by, the
Credit Documents, no material adverse changes have occurred in the Companies'
consolidated (if applicable) financial condition from that shown in the Current
Financials.

         7.7 Solvency. On each Borrowing Date, each Company is, and after giving
effect to the requested Borrowing will be, Solvent.

         or aware of the threat of, any Litigation involving any Company, or any
         of their respective properties, which if adversely determined against
         any of them, reasonably could be expected to result in a Material
         Adverse Event, and



                                       31
<PAGE>   37

compliance with all requisite Governmental Requirements, and as so prepared,
have been properly filed (or extensions have been granted) and (ii) all Taxes

         Authority that it has any actual or potential Environmental Liability,
         and no Company has knowledge that it has any Environmental Liability,

any property of any Company except Permitted Liens. Except for the Credit
Documents, no Company is party or subject to any agreement, instrument or order

be successfully completed on a timely basis. To the knowledge of Borrower, the

reasonably be expected to have a material adverse effect on the Companies or
their business. Prior to the date hereof, Borrower has disclosed in writing to
Administrative Agent and Lenders the steps that Borrower has taken to become
Year 2000 compliant and the costs Borrower expects to incur in connection

issue.

furnished, true, complete and accurate in all material respects or where
estimates or projections were or will be therein made and so designated, based
on good faith, reasonable estimates or projections on the date the information
is stated or certified.

         distribution, accurate and complete copies of all reports and other

                  (f) Employee Plans. As soon as possible and within 30 days

         event under Section 4043(b) of Title IV of ERISA with respect to any
         Employee Plan subject to ERISA has occurred, or that the PBGC has
         instituted or will institute proceedings under ERISA to terminate that
         plan, deliver a certificate of a Responsible Officer of Borrower
         setting forth details as to that reportable event and the action which
         Borrower or an ERISA Affiliate, as the case may be, proposes to take
         with respect to it, together with a copy of any notice of that
         reportable event which may be required to be filed with the PBGC, or

         to be terminated, as the case may be. For all purposes of this section,
         Borrower is deemed to have all knowledge of all facts attributable to
         the plan administrator under ERISA.

                  (g) Other Notices. Promptly after Borrower knows or receives
         any notification thereof (whichever shall first occur), notice of (i)
         the existence and status of any Litigation or Environmental Liability
         that if determined adversely to any Company, could reasonably be
         expected to result in a Material Adverse Event, (ii) any change in any
         fact or circumstance (other than of an inconsequential nature)
         represented or warranted by any Company in any Credit Document, and
         (iii) an Event of Default, Potential Default or Material Adverse Event,
         specifying the nature thereof and what action the Companies have taken,
         are taking and propose to take.

                  (h) Other Information. Promptly when reasonably requested by
         Administrative Agent or any Lender, such information (not otherwise
         required to be furnished under this agreement) about any Company's
         business affairs, assets, liabilities, results of operation and
         financial condition (all in form and substance satisfactory to
         Administrative Agent or that Lender).

         8.2 Use of Credit. Borrower shall use the proceeds of Borrowings only
for the purposes represented in this agreement.

         8.3 Books and Records. Each Company shall maintain books, records and
accounts necessary to prepare Financials in accordance with GAAP.

         8.4 Inspections. Upon reasonable request and at least 5-days' advance
notice (but during the pendency of an Event of Default, no advance notice is
required), each Company shall allow Administrative Agent or any Lender (or their
respective Representatives) to inspect any of that Company's properties, to
review reports, files and other records and to make and take away copies, to
conduct tests or investigations and to discuss any of its affairs, conditions
and finances with its other creditors, directors, officers, employees, outside
accountants or representatives from time to time, during reasonable business
hours (but during the pendency of an Event of Default, at any time). Without
limiting the foregoing, the Companies shall allow Administrative Agent to
perform field examinations to test such systems and controls of the Companies as
it deems appropriate. Borrower shall reimburse Administrative Agent for the
reasonable expenses of one such field exam every twelve months (the expected
expense relating to each such annual field exam is $10,000). Additional field
exams may be conducted at the sole expense of Administrative Agent and Lenders;
provided, however, that Borrower shall reimburse Administrative Agent for the
reasonable expenses of follow-up examinations by Administrative Agent that are
reasonably required by Administrative Agent to address matters of concern
arising as a result of any prior field exam.

         8.5 Taxes. Each Company shall promptly pay when due any and all Taxes
except Taxes that are being contested in good faith by lawful proceedings
diligently conducted, against which reserve or other provision required by GAAP
has been made and in respect of which levy and execution of any Lien sufficient
to be enforced has been and continues to be stayed.

         8.6 Payment of Obligation. Each Company shall promptly pay (or renew
and extend) all of its obligations as they become due (unless the obligations,

an invoice describing the costs, fees and expenses in reasonable detail,
Borrower shall pay (i) all costs, fees and expenses paid or incurred by or on

counsel in connection with the negotiation, preparation, delivery and execution
of the Credit Documents and any related amendment, waiver or consent) and (ii)
all reasonable costs and expenses incurred by Administrative Agent in connection
with the enforcement of the obligations of any Company under the Credit
Documents or the exercise of any Rights under the Credit Documents (including,
without limitation, reasonable allocated costs of in-house counsel, other
reasonable attorneys' fees and court costs), all of which are part of the
Obligation, bearing interest (if not paid within fifteen Business Days after
demand accompanied by an invoice describing the costs, fees and expenses in
reasonable detail) on the portion thereof from time to time unpaid at the
Default Rate until paid.

         8.8 Maintenance of Existence, Assets and Business. Each Company shall
(i) except as permitted in SECTION 9.9 and SECTION 9.10, maintain its corporate
or partnership (as applicable) existence and good standing in its state of
incorporation or formation (as applicable) and (ii) except where the failure to
perform any of the following could not reasonably be expected to result in a
Material Adverse Event (a) maintain its authority to transact business and good
standing in all other states, (b) maintain all licenses, permits and franchises
(including, without limitation, Environmental Permits) necessary or desirable
for its business and (c) keep all of its assets that are useful in and necessary
to its business in good working order and condition (ordinary wear and tear

         8.9 Insurance. Each Company shall, at its cost and expense, maintain
with financially sound, responsible and reputable insurance companies or
associations, or as to workers' compensation or similar insurance, with an
insurance fund or by self-insurance authorized by the jurisdictions in which it
operates, insurance concerning its properties and businesses against casualties
and contingencies and of types and in amounts (and with co-insurance and
deductibles) as is customary in the case of similar businesses. In addition,
Borrower shall and shall cause each other Company to, (i) name Administrative
Agent as additional insured on all general and comprehensive liability insurance
and as loss payee on all insurance covering any Collateral (or any portion
thereof), (ii) deliver copies of the policies and endorsements for the insurance
required by this SECTION 8.9 to Administrative Agent promptly after issuance and
renewal of each and (iii) cause each policy of insurance to provide that it will
not be cancelled or modified (as to term, coverage, scope, property or risks
covered, change or addition of loss payee or additional insured or otherwise)
without 30 days prior written notice to Administrative Agent.

         8.10 Compliance with Governmental Requirements. Each Company shall (i)
operate and manage its businesses and otherwise conduct its affairs in
compliance with all Governmental Requirements (including without limitation, all
Environmental Governmental Requirements and Environmental Permits) except to the
extent noncompliance reasonably could be expected not to constitute a Material
Adverse Event, (ii) promptly deliver to Administrative Agent a copy of any
notice received from any Governmental Authority alleging that any Company is not
in compliance with any Governmental Requirements (including any Environmental
Governmental Requirements or Environmental Permits) if the allegation reasonably
could constitute a Material Adverse Event and (iii) promptly deliver to
Administrative Agent a copy of any notice received from any Governmental
Authority alleging that any Company has any potential Environmental Liability if
the allegation reasonably could constitute a Material Adverse Event.

         8.11 Subsidiary Guaranties and Pledges. Borrower shall cause all of its
present and future Domestic Subsidiaries, whether now existing or in the future

         8.12 Indemnification.

                  (a) AS USED IN THIS SECTION: (i) "INDEMNITOR" MEANS BORROWER
         AND (PURSUANT TO ITS GUARANTY OR ITS EXECUTION AND DELIVERY OF, OR
         CONSENT TO, ANY OTHER CREDIT DOCUMENT) EACH OTHER COMPANY; (ii)
         "INDEMNITEE" MEANS ADMINISTRATIVE AGENT, EACH LENDER, EACH PRESENT AND
         FUTURE AFFILIATE OF ADMINISTRATIVE AGENT AND EACH LENDER, EACH PRESENT
         AND FUTURE REPRESENTATIVE OF ADMINISTRATIVE AGENT AND EACH LENDER OR
         ANY OF THOSE AFFILIATES AND EACH PRESENT AND FUTURE SUCCESSOR AND
         ASSIGN OF ADMINISTRATIVE AGENT AND EACH LENDER OR ANY OF THOSE
         AFFILIATES OR REPRESENTATIVES; AND (iii) "INDEMNIFIED LIABILITIES"
         MEANS ALL PRESENT AND FUTURE, KNOWN AND UNKNOWN, FIXED AND CONTINGENT,
         ADMINISTRATIVE, INVESTIGATIVE, JUDICIAL AND OTHER CLAIMS, DEMANDS,
         ACTIONS, CAUSES OF ACTION, INVESTIGATIONS, SUITS, PROCEEDINGS, AMOUNTS
         PAID IN SETTLEMENT, DAMAGES, JUDGMENTS, PENALTIES, COURT COSTS,
         LIABILITIES AND OBLIGATIONS, AND ALL PRESENT AND FUTURE COSTS, EXPENSES
         AND DISBURSEMENTS (INCLUDING ALL REASONABLE ATTORNEYS' FEES AND
         EXPENSES WHETHER OR NOT SUIT OR OTHER PROCEEDING EXISTS OR ANY
         INDEMNITEE IS PARTY TO ANY SUIT OR OTHER PROCEEDING) IN ANY WAY RELATED
         TO ANY OF THE FOREGOING, THAT MAY AT ANY TIME BE IMPOSED ON, INCURRED
         BY, OR ASSERTED AGAINST, ANY INDEMNITEE AND IN ANY WAY RELATING TO OR
         ARISING OUT OF ANY (1) CREDIT DOCUMENT OR TRANSACTION CONTEMPLATED BY
         ANY CREDIT DOCUMENT, (2) ENVIRONMENTAL LIABILITY IN ANY WAY RELATED TO
         ANY COMPANY, OR ACT, OMISSION, STATUS, OWNERSHIP, OR OTHER
         RELATIONSHIP, CONDITION, OR CIRCUMSTANCE CONTEMPLATED BY, CREATED
         UNDER, OR ARISING PURSUANT TO OR IN CONNECTION WITH ANY CREDIT
         DOCUMENT, OR (3) INDEMNITEE'S SOLE OR CONCURRENT ORDINARY NEGLIGENCE.

                  (b) EACH INDEMNITOR AGREES, JOINTLY AND SEVERALLY, TO
         INDEMNIFY PROTECT AND DEFEND EACH INDEMNITEE FROM AND AGAINST, HOLD
         EACH INDEMNITEE HARMLESS FROM AND AGAINST, AND ON DEMAND PAY OR
         REIMBURSE EACH INDEMNITEE FOR, ALL INDEMNIFIED LIABILITIES.

                  (c) THE FOREGOING PROVISIONS (i) ARE NOT LIMITED IN AMOUNT
         EVEN IF THAT AMOUNT EXCEEDS THE OBLIGATION, (ii) INCLUDE, WITHOUT
         LIMITATION, REASONABLE FEES AND EXPENSES OF ATTORNEYS AND OTHER COSTS
         AND EXPENSES OF LITIGATION OR PREPARING FOR LITIGATION AND DAMAGES OR
         INJURY TO PERSONS, PROPERTY, OR NATURAL RESOURCES ARISING UNDER ANY
         STATUTORY OR COMMON LAW GOVERNMENTAL REQUIREMENT, PUNITIVE DAMAGES,
         FINES, AND OTHER PENALTIES, AND (iii) ARE NOT AFFECTED BY THE SOURCE OR
         ORIGIN OF ANY HAZARDOUS SUBSTANCE, AND (iv) ARE NOT AFFECTED BY ANY
         INDEMNITEE'S INVESTIGATION, ACTUAL OR CONSTRUCTIVE KNOWLEDGE, COURSE OF
         DEALING, OR WAIVER.

                  (d) However, no Indemnitee is entitled to be indemnified under
         the Credit Documents for its own fraud, gross negligence, or wilful
         misconduct.

                  (e) Although failure to do so does not reduce or impair any
         Indemnitor's obligations under this section, each Indemnitee shall
         promptly notify Borrower of any event about which the Indemnitee has
         received written notice and that is reasonably likely to result in any
         Indemnified Liability. Each Indemnitor may, at its own cost and
         expense, participate in the defense in any proceeding involving any
         Indemnified Liability. If no Event of Default or Potential Default
         exists, Indemnitors may assume the defense in that proceeding on behalf
         of the applicable Indemnitees, including the employment of counsel if
         first approved (which approval may not be unreasonably withheld) by the
         applicable Indemnitees. If Indemnitors assume any defense, they shall
         keep the applicable Indemnitees fully advised of the status of, and
         shall consult with, and receive the concurrence of, those Indemnitees
         before taking any material position in respect of, that proceeding.
         If Indemnitors consent, if an Event of Default, Potential Default or
         Material Adverse Event exists or if any Indemnitee reasonably



                                       37
<PAGE>   43


         determines that an actual conflict of interests exists between
         Indemnitors and that Indemnitee with respect to the subject matter of
         the proceeding or that Indemnitors are not diligently pursuing the
         defense, then (i) that Indemnitee may, at Indemnitors' joint and
         several expense, employ counsel to represent that Indemnitee that is
         separate from counsel for Indemnitors or any other Person in that
         proceeding and (ii) Indemnitors are no longer entitled to assume the
         defense on behalf of that Indemnitee. No Indemnitor may agree to the
         settlement of any Indemnified Liability, or any matters or issues
         material to or necessary for the resolution of any such liability,
         without the prior written consent of the applicable Indemnitees unless,
         as agreed to in writing by an Indemnitee, that settlement fully
         relieves those Indemnitees of any liability whatsoever for that
         Indemnified Liability. If an Indemnitee agrees to the settlement of any
         Indemnified Liability without the prior written consent of Indemnitors
         (which consent may not be unreasonably withheld), then Indemnitors are
         no longer obligated for that Indemnified Liability in respect of that
         Indemnitee.

                  (f) THE PROVISIONS OF AND INDEMNIFICATION AND OTHER
         UNDERTAKINGS UNDER THIS SECTION SURVIVE THE FORECLOSURE OF ANY LENDER
         LIEN OR ANY TRANSFER IN LIEU OF THAT FORECLOSURE, THE SALE OR OTHER
         TRANSFER OF ANY COLLATERAL OR REAL PROPERTY TO ANY PERSON, THE
         SATISFACTION OF THE OBLIGATION, THE TERMINATION OF THE CREDIT DOCUMENTS
         AND THE RELEASE OF ANY OR ALL LENDER LIENS.

         8.13 Post-Closing Covenants. Notwithstanding any other provision of
this agreement or any other Credit Document:

                  (a) Interest Rate Hedging Agreement. Within 180 days of the
         Closing Date, Borrower shall enter into a Hedging Agreement with
         Administrative Agent, any Lender, or any other bank incorporated under
         the Governmental Requirements of the United States of America or any of
         its states with a short-term certificate of deposit credit rating of at
         least P-2 by Moody's Investors Service, Inc., or A-2 by Standard &
         Poor's Corporation, on terms acceptable to Administrative Agent and
         Borrower, regarding the hedging of Borrower's interest rate risk with
         respect to a $20,000,000 portion of the Obligation.

                  (b) Delivery of Certain Stock Certificates. Within 30 days of
         the Closing Date, Borrower shall deliver to Administrative Agent the
         original stock certificates covering the shares of Detection Systems,
         Inc. pledged as Collateral as described on SCHEDULE 5-B of the Security
         Agreement (together with all appropriate stock powers executed in
         blank). Within 180 days of the Closing Date, Borrower shall deliver to
         Administrative Agent the original stock certificates covering the
         shares of the companies (other than Detection Systems, Inc.) pledged as
         Collateral as described on SCHEDULE 5-B of the Security Agreement
         (together with all appropriate stock powers executed in blank).

                  (c) Other Deliveries. Borrower shall cooperate with
         Administrative Agent's counsel in a timely manner to obtain, complete,
         file or otherwise complete all collateral documents not obtained on the
         Closing Date.

SECTION 9. NEGATIVE COVENANTS. For so long as any Lender is committed to lend or
issue LCs under this agreement and until the Obligation has been fully paid and
performed, Borrower covenants and agrees with Administrative Agent and Lenders
as follows:

         9.1 Payroll Taxes. No Company may directly or indirectly use any
proceeds of any Borrowing (i) for any purpose other than as represented in this
agreement, or (ii) for the payment of wages of employees unless a timely payment

to be deducted and withheld with respect to such wages is also made.

                           or Material Adverse Event (y) exists on the date any
                           such Debt is created, incurred or assumed or (z)
                           arises as a result of, or after giving effect to, any

and before the date of determination plus (c) 100% of the net (i.e., gross less
usual and customary brokerage and after related costs and expenses) proceeds
from the issuance and sale of any equity securities by any Company after
September 30, 1998, other than the proceeds of any issuance and sale of any
capital stock which is required to be redeemed, or is redeemable at the option

(d) the amount of any stock purchases permitted by SECTION 9.8(vi) or (vii)

expenditures for the acquisition, construction, improvement or replacement of

         10.5 Liquidity Ratio. The ratio of the Companies' consolidated Adjusted
Current Assets to the Companies' consolidated Adjusted Current Liabilities shall
at all times exceed 1.25 to 1.00.

         10.6 Effect of Special Charges. The financial covenants in this SECTION
10 have been negotiated assuming that Borrower will take a $1,000,000 special
charge in the fourth quarter of its fiscal year 1998 (relating to discontinued
operations) and a $1,500,000 special charge in the first quarter of its fiscal
year 1999 (relating to a plant closure and consolidation of its European
operations). If for any reason the $1,000,000 special charge described above is
not taken in the fourth quarter of fiscal year 1998, Borrower agrees to
negotiate in good faith with Administrative Agent and Lenders to amend the
financial covenant requirements in this SECTION 10 to reflect ratios and amounts
that would otherwise have been agreed upon by Administrative Agent and Lenders
on the Closing Date had it not been for consideration of this special charge. If
for any reason the $1,500,000 special charge described above is taken in the
second quarter of fiscal year 1999 rather than the first quarter, Borrower,
Administrative Agent and Lenders hereby agree that the minimum Fixed Charge
Coverage Ratio as set forth in SECTION 10.2 shall be deemed to be amended to
2.50 to 1.00 for the quarter ended March 31, 1999, with no further action
required by any party. If for any reason the $1,500,000 special charge described
above is taken in the third quarter of fiscal year 1999 rather than the first or
second quarter, Borrower, Administrative Agent and Lenders hereby agree that the
minimum Fixed Charge Coverage Ratio as set forth in SECTION 10.2 shall be deemed
to be amended to 2.25 to 1.00 for the quarter ended June 30, 1999, with no
further action required by any party. If for any reason the $1,500,000 special
charge described above is not taken in either the first, second or third
quarters of fiscal 1999, Borrower agrees to negotiate in good faith with
Administrative Agent and Lenders to amend the financial covenant requirements in
this SECTION 10 to reflect ratios and amounts that would otherwise have been
agreed upon by Administrative Agent and Lenders on the Closing Date had it not
been for consideration of this special charge.

liability or obligations under any Credit Document to which it is a party except
in accordance with that document's express provisions, or any Lender Lien shall
fail to constitute a valid, perfected-first priority lien in favor of
Administrative Agent for Lenders, except in accordance with the express
provisions of any applicable Credit Document.

         11.13 Material Agreement Default or Cancellation. The default under, or
breach or cancellation of, any agreement or other contractual arrangement to
which any Company is a party or beneficiary or by which any of its property is
bound or subject, which reasonably could be expected to result in any (i)
significant impairment of (a) the ability of Borrower or any other Company to
perform any of its payment or other material obligations under any Credit
Document or (b) the ability of Administrative Agent or Lenders to enforce any of
those obligations or any of their respective Rights under the Credit Documents,
(ii) significant and adverse effect on the business, management or financial
condition of the Borrower or of the Companies as a whole, as represented to
Lenders in the Financials then most recently received by them or (iii) event or
circumstance that could result in an Event of Default or Potential Default
pursuant to SECTIONS 11.1 through 11.13 (inclusive) or SECTION 11.14.



                                       46

         11.14 LCs. Administrative Agent is served with, or becomes subject to,
a court order, injunction, or other process or decree restraining or seeking to
restrain it from paying any amount under any LC and either (a) a drawing has
occurred under the LC, and Borrower has refused to reimburse Administrative
Agent for payment, or (b) the expiration date of the LC has occurred, but the
Right of the beneficiary to draw under the LC has been extended past the
expiration date in connection with the pendency of the related court action or
proceeding, and Borrower has failed to deposit with Administrative Agent cash
collateral in an amount equal to Administrative Agent's maximum exposure under
the LC.

SECTION 12. RIGHTS AND REMEDIES.

         12.1 Remedies Upon Event of Default.

                  (a) Debtor Relief. If an Event of Default exists under SECTION
         11.3, the commitment to extend credit under this agreement
         automatically terminates and the entire unpaid principal balance of the
         Obligation, together with all interest accrued thereon, and all other
         amounts then accrued and unpaid, automatically become and shall be due
         and payable without any action of any kind whatsoever.

                  (b) Other Events of Default. If any Event of Default exists,
         Administrative Agent may (with the consent of, and must, upon the
         request of Required Lenders), do any one or more of the following: (i)
         If the maturity of the Obligation has not already been accelerated
         under SECTION 12.1(a), declare the entire unpaid principal balance of
         all or any part of the Obligation, together with all interest accrued
         thereon, and all other amounts then accrued and unpaid, immediately due
         and payable, whereupon it is due and payable; (ii) terminate the
         commitments of Lenders to extend credit under this agreement; (iii)
         reduce any claim to judgment; (iv) demand payment of an amount equal to
         the LC Exposure then existing and retain as collateral for the LC
         Exposure any amounts received from any Company, from any property of
         any Company, through offset or otherwise; and (v) exercise any and all
         other legal or equitable Rights afforded by the Credit Documents, by
         applicable Governmental Requirements or otherwise at law or in equity.

                  (c) Offset. If an Event of Default exists, to the extent not
         prohibited by applicable Governmental Requirements, each Lender may
         exercise the Rights of offset and banker's lien against each and every
         account and other property, or any interest therein, which any Company
         may now or hereafter have with, or which is now or hereafter in the
         possession of, that Lender to the extent of the full amount of the
         Obligation owed to that Lender.

         12.2 Company Waivers. To the extent not prohibited by applicable
Governmental Requirements, Borrower and (pursuant to its Guaranty or its
execution and delivery of, or consent to, any other Credit Document) each other
Company waives, in respect to any action taken by Administrative Agent or
Lenders at any time and from time to time pursuant to SECTION 12.1, presentment,
demand for payment, protest, acceleration, notice of protest and nonpayment,
NOTICE OF INTENTION TO ACCELERATE, NOTICE OF ACCELERATION, and all other notices
and acts, and agrees that its liability with respect to all or any part of the
Obligation is not affected by any renewal or extension in the time of payment of
all or any part of the Obligation, by any indulgence, increase or other
modification to, or by any release or change in any security for the payment of,
all or any part of the Obligation.

         12.3 Performance by Administrative Agent. If any Company's covenant,
duty or agreement is not performed in accordance with the terms of the Credit
Documents, Administrative Agent may at its option (but subject to the approval
of Required Lenders), perform or attempt to perform that covenant, duty or
agreement on behalf of that Company, and any amount expended by or on behalf of
Administrative Agent in its performance or attempted performance is payable by
the Companies, jointly and severally, to Administrative Agent on demand, becomes
part of the Obligation, and bears interest on the portion thereof from time to
time unpaid at the Default Rate from the date of Administrative Agent's
expenditure until paid. However,



                                       47
<PAGE>   53


Administrative Agent does not assume and shall never have, except by its express
written consent, any liability or responsibility for the performance of any
Company's covenants, duties or agreements.

         12.4 Not in Control. Nothing in any Credit Document gives or may be
deemed to give to Administrative Agent or any Lender the Right to exercise
control over any Company's Real Property, other assets, affairs or management or
to preclude or interfere with any Company's compliance with any Governmental
Requirement or require any act or omission by any Company that may be harmful to
Persons or property. Any "Material Adverse Event" or other materiality or
substantiality qualifier of any representation, warranty, covenant, agreement or
other provision of any Credit Document is included for credit documentation
purposes only and does not imply and should not be deemed to mean that
Administrative Agent or any Lender acquiesces in any non-compliance by any
Company with any applicable Governmental Requirement, document, or otherwise or
does not expect the Companies to promptly, diligently and continuously carry out
all appropriate removal, remediation, compliance, closure or other activities
required or appropriate in accordance with all Environmental Governmental
Requirements. Administrative Agent's and Lenders' power is limited to the Rights
provided in, or referred to by, the Credit Documents. All of those Rights exist
solely to preserve and protect the Collateral and to assure payment and
performance of the Obligation in accordance with the terms of the Credit
Documents, and may be exercised in a manner determined to be appropriate by
Administrative Agent or Lenders in their sole respective good faith business
judgment.

         12.5 Course of Dealing. The acceptance by Administrative Agent or
Lenders of any partial payment on the Obligation is not a waiver of any Event of
Default then existing. No waiver by Administrative Agent, Required Lenders or
Lenders of any Event of Default is a waiver of any other then-existing or
subsequent Event of Default. No delay or omission by Administrative Agent,
Required Lenders or Lenders in exercising any Right under the Credit Documents
impairs that Right or is a waiver thereof or any acquiescence therein, nor will
any single or partial exercise of any Right preclude other or further exercise
thereof or the exercise of any other Right under the Credit Documents or
otherwise.

         12.6 Cumulative Rights. All Rights available to Administrative Agent,
Required Lenders and Lenders under the Credit Documents are cumulative of and in
addition to all other Rights granted to Administrative Agent, Required Lenders
and Lenders at law or in equity, whether or not the Obligation is due and
payable and whether or not Administrative Agent, Required Lenders or Lenders
have instituted any suit for collection, foreclosure, or other action in
connection with the Credit Documents.

         12.7 Application of Proceeds. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation according to SECTION 3.

         12.8 Certain Proceedings. Borrower shall promptly execute and deliver,
or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or Required Lenders reasonably request in connection with
the obtaining of any consent, approval, registration (other than securities law
registrations), qualification, permit, license or authorization of any
Governmental Authority or other Person necessary or appropriate for the
effective exercise of any Rights under the Credit Documents. Because Borrower
agrees that Administrative Agent's and Required Lenders' remedies under
applicable Governmental Requirements for failure of Borrower to comply with the
provisions of this section would be inadequate and that failure would not be
adequately compensable in damages, Borrower agrees that the covenants of this
section may be specifically enforced.

         12.9 Expenditures by Administrative Agent or Lenders. Any sums spent by
Administrative Agent or any Lender in the exercise of any Right under any Credit
Document is payable by the Companies to Administrative Agent within 15 Business
Days of written demand, becomes part of the Obligation, and bears interest on
the portion thereof from time to time unpaid at the Default Rate from the date
spent until the date repaid.



                                       48
<PAGE>   54


         12.10 Diminution in Value of Collateral. Neither Administrative Agent
nor any Lender has any liability or responsibility whatsoever for any diminution
in or loss of value of any collateral now or in the future securing payment or
performance of any of the Obligation (other than diminution in or loss of value
caused by its own gross negligence or willful misconduct).

SECTION 13. ADMINISTRATIVE AGENT AND LENDERS.

         13.1 Administrative Agent.

                  (a) Appointment. Each Lender appoints Administrative Agent
         (including, without limitation, each successor Administrative Agent in
         accordance with this SECTION 13) as its nominee and agent to act in its
         name and on its behalf (and Administrative Agent and each such
         successor accepts that appointment): (i) To act as its nominee and on
         its behalf in and under all Credit Documents; (ii) to arrange the means
         whereby its funds are to be made available to Borrower under the Credit
         Documents; (iii) to take any action that it properly requests under the
         Credit Documents (subject to the concurrence of other Lenders as may be
         required under the Credit Documents); (iv) to receive all documents and
         items to be furnished to it under the Credit Documents; (v) to be the
         secured party, mortgagee, beneficiary, recipient and similar party in
         respect of any collateral for the benefit of Lenders; (vi) to promptly
         distribute to it all material information, requests, documents, and
         items received from Borrower under the Credit Documents; (vii) to
         promptly distribute to it its ratable part of each payment or
         prepayment (whether voluntary, as proceeds of collateral upon or after
         foreclosure, as proceeds of insurance thereon, or otherwise) in
         accordance with the terms of the Credit Documents; and (viii) to
         deliver to the appropriate Persons requests, demands, approvals, and
         consents received from it. However, Administrative Agent may not be
         required to take any action that exposes it to personal liability or
         that is contrary to any Credit Document or applicable Governmental
         Requirements.

                  (b) Successor. Administrative Agent may assign all of its
         Rights and obligations as Administrative Agent under the Credit
         Documents to any of its Affiliates, which Affiliate shall then be the
         successor Administrative Agent under the Credit Documents.
         Administrative Agent may also voluntarily resign and shall resign upon
         the request of Required Lenders for cause (i.e., Administrative Agent
         is continuing to fail to perform its responsibilities as Administrative
         Agent under the Credit Documents). If the initial or any successor
         Administrative Agent ever ceases to be a party to this agreement or if
         the initial or any successor Administrative Agent ever resigns (whether
         voluntarily or at the request of Required Lenders), then Required
         Lenders shall (which, if no Event of Default or Potential Default
         exists, is subject to Borrower's approval that may not be unreasonably
         withheld) appoint the successor Administrative Agent from among Lenders
         (other than the resigning Administrative Agent). If Required Lenders
         fail to appoint a successor Administrative Agent within 30 days after
         the resigning Administrative Agent has given notice of resignation or
         Required Lenders have removed the resigning Administrative Agent, then
         the resigning Administrative Agent may, on behalf of Lenders, appoint a
         successor Administrative Agent, which must be a commercial bank having
         a combined capital and surplus of at least $1,000,000,000 (as shown on
         its most recently published statement of condition). Upon its
         acceptance of appointment as successor Administrative Agent, the
         successor Administrative Agent succeeds to and becomes vested with all
         of the Rights of the prior Administrative Agent, and the prior
         Administrative Agent is discharged from its duties and obligations of
         Administrative Agent under the Credit Documents (but, when used in
         connection with LCs issued and outstanding before the appointment of
         the successor Administrative Agent, "Administrative Agent" shall
         continue to refer solely to the prior Administrative Agent, but any LCs
         issued or renewed after the appointment of any successor Administrative
         Agent shall be issued or renewed by the successor Administrative
         Agent), and each Lender shall execute the documents that any Lender,
         the resigning or removed Administrative Agent, or the successor
         Administrative Agent reasonably request to reflect the change. After
         any Administrative Agent's resignation or removal as Administrative
         Agent under



                                       49
<PAGE>   55


         the Credit Documents, the provisions of this section inure to its
         benefit as to any actions taken or not taken by it while it was
         Administrative Agent under the Credit Documents.

                  (c) Rights as Lender. Administrative Agent, in its capacity as
         a Lender, has the same Rights under the Credit Documents as any other
         Lender and may exercise those Rights as if it were not acting as
         Administrative Agent. The term "Lender", unless the context otherwise
         indicates, includes Administrative Agent. Administrative Agent's
         resignation or removal does not impair or otherwise affect any Rights
         that it has or may have in its capacity as an individual Lender. Each
         Lender and Borrower agree that Administrative Agent is not a fiduciary
         for Lenders or for Borrower but is simply acting in the capacity
         described in this agreement to alleviate administrative burdens for
         Borrower and Lenders, that Administrative Agent has no duties or
         responsibilities to Lenders or Borrower except those expressly set
         forth in the Credit Documents, and that Administrative Agent in its
         capacity as a Lender has the same Rights as any other Lender.

                  (d) Other Activities. Administrative Agent or any Lender may
         now or in the future be engaged in one or more loan, letter of credit,
         leasing, hedging agreement, or other financing transactions with
         Borrower, act as trustee or depositary for Borrower, or otherwise be
         engaged in other transactions with Borrower (collectively, the "OTHER
         ACTIVITIES") not the subject of the Credit Documents. Without limiting
         the Rights of Lenders specifically set forth in the Credit Documents,
         neither Administrative Agent nor any Lender is responsible to account
         to the other Lenders for those other activities, and no Lender shall
         have any interest in any other Lender's activities, any present or
         future guaranties by or for the account of Borrower that are not
         contemplated by or included in the Credit Documents, any present or
         future offset exercised by Administrative Agent or any Lender in
         respect of those other activities, any present or future property taken
         as security for any of those other activities, or any property now or
         hereafter in Administrative Agent's or any other Lender's possession or
         control that may be or become security for the obligations of Borrower
         arising under the Credit Documents by reason of the general description
         of indebtedness secured or of property contained in any other
         agreements, documents, or instruments related to any of those other
         activities (but, if any payments in respect of those guaranties or that
         property or the proceeds thereof is applied by Administrative Agent or
         any Lender to reduce the Obligation, then each Lender is entitled to
         share ratably in the application as provided in the Credit Documents).

         13.2 Expenses. Each Lender shall pay its Pro Rata Part of any
reasonable expenses (including, without limitation, court costs, reasonable
attorneys' fees and other costs of collection) incurred by Administrative Agent
(while acting in such capacity) in connection with any of the Credit Documents
if Administrative Agent is not reimbursed from other sources within 30 days
after incurrence. Each Lender is entitled to receive its Pro Rata Part of any
reimbursement that it makes to Administrative Agent if Administrative Agent is
subsequently reimbursed from other sources.

         13.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Credit Documents, nothing in the Credit Documents gives any Lender any
advantage over any other Lender insofar as the Obligation is concerned or
relieves any Lender from ratably absorbing any losses sustained with respect to
the Obligation (except to the extent unilateral actions or inactions by any
Lender result in Borrower or any other obliger on the Obligation having any
credit, allowance, setoff, defense, or counterclaim solely with respect to all
or any part of that Lender's Pro Rata Part of the Obligation).

         13.4 Delegation of Duties; Reliance. Lenders may perform any of their
duties or exercise any of their Rights under the Credit Documents by or through
Administrative Agent, and Lenders and Administrative Agent may perform any of
their duties or exercise any of their Rights under the Credit Documents by or
through their respective Representatives. Administrative Agent, Lenders, and
their respective Representatives (a) are entitled to rely upon (and shall be
protected in relying upon) any written or oral statement believed by it or them
to be genuine and correct and to have been signed or made by the proper Person
and, with respect to legal 



                                       50
<PAGE>   56


matters, upon opinion of counsel selected by Administrative Agent or that Lender
(but nothing in this CLAUSE (a) permits Administrative Agent to rely on (i) oral
statements if a writing is required by this agreement or (ii) any other writing
if a specific writing is required by this agreement), (b) are entitled to deem
and treat each Lender as the owner and holder of its portion of the Obligation
for all purposes until, written notice of the assignment or transfer is given to
and received by Administrative Agent (and any request, authorization, consent,
or approval of any Lender is conclusive and binding on each subsequent holder,
assignee, or transferee of or Participant in that Lender's portion of the
Obligation until that notice is given and received), (c) are not deemed to have
notice of the occurrence of an Event of Default unless a responsible officer of
Administrative Agent, who handles matters associated with the Credit Documents
and transactions thereunder, has actual knowledge or Administrative Agent has
been notified by a Lender or Borrower, and (d) are entitled to consult with
legal counsel (including counsel for Borrower), independent accountants, and
other experts selected by Administrative Agent and are not liable for any action
taken or not taken in good faith by it in accordance with the advice of counsel,
accountants, or experts.

         13.5 Limitation of Administrative Agent's Liability.

                  (a) Exculpation. Neither Administrative Agent nor any of its
         Affiliates or Representatives will be liable for any action taken or
         omitted to be taken by it or them under the Credit Documents in good
         faith and believed by it or them to be within the discretion or power
         conferred upon it or them by the Credit Documents or be responsible for
         the consequences of any error of judgment (except for fraud, gross
         negligence, or willful misconduct), and neither Administrative Agent
         nor any of its Affiliates or Representatives has a fiduciary
         relationship with any Lender by virtue of the Credit Documents (but
         nothing in this agreement negates the obligation of Administrative
         Agent to account for funds received by it for the account of any
         Lender).

                  (b) Indemnity. Unless indemnified to its satisfaction against
         loss, cost, liability, and expense, Administrative Agent may not be
         compelled to do any act under the Credit Documents or to take any
         action toward the execution or enforcement of the powers thereby
         created or to prosecute or defend any suit in respect of the Credit
         Documents. If Administrative Agent requests instructions from Lenders,
         or Required Lenders, as the case may be, with respect to any act or
         action in connection with any Credit Document, Administrative Agent is
         entitled to refrain (without incurring any liability to any Person by
         so refraining) from that act or action unless and until it has received
         instructions. In no event, however, may Administrative Agent or any of
         its Representatives be required to take any action that it or they
         determine could incur for it or them criminal or onerous civil
         liability. Without limiting the generality of the foregoing, no Lender
         has any right of action against Administrative Agent as a result of
         Administrative Agent's acting or refraining from acting under this
         agreement in accordance with instructions of Required Lenders.

                  (c) Reliance. Administrative Agent is not responsible to any
         Lender or any Participant for, and each Lender represents and warrants
         that it has not relied upon Administrative Agent in respect of, (i) the
         creditworthiness of any Company and the risks involved to that Lender,
         (ii) the effectiveness, enforceability, genuineness, validity, or the
         due execution of any Credit Document (except by Administrative Agent),
         (iii) any representation, warranty, document, certificate, report, or
         statement made therein (except by Administrative Agent) or furnished
         thereunder or in connection therewith, (iv) the adequacy of any
         collateral now or hereafter securing the Obligation or the existence,
         priority, or perfection of any Lien now or hereafter granted or
         purported to be granted on the collateral under any Credit Document, or
         (v) observation of or compliance with any of the terms, covenants, or
         conditions of any Credit Document on the part of any Company. EACH
         LENDER AGREES TO INDEMNIFY ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES
         AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S
         COMMITMENT PERCENTAGE OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
         DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE
         EXPENSES, AND REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER



                                       51
<PAGE>   57


         THAT MAY BE IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY
         WAY RELATING TO OR ARISING OUT OF THE CREDIT DOCUMENTS OR ANY ACTION
         TAKEN OR OMITTED BY THEM UNDER THE CREDIT DOCUMENTS IF ADMINISTRATIVE
         AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY
         ANY COMPANY. ALTHOUGH ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES HAVE
         THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN
         ORDINARY NEGLIGENCE, ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES DO
         NOT HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR
         THEIR OWN FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

         13.6 Event of Default. While an Event of Default exists, Lenders agree
to promptly confer in order that Required Lenders or Lenders, as the case may
be, may agree upon a course of action for the enforcement of the Rights of
Lenders. Administrative Agent is entitled to act or refrain from taking any
action (without incurring any liability to any Person for so acting or
refraining) unless and until it has received instructions from Required Lenders.
In actions with respect to any Company's property, Administrative Agent is
acting for the ratable benefit of each Lender.

         13.7 Collateral Matters.

                  (a) General Authorization. Each Lender authorizes and directs
         Administrative Agent to enter into the Credit Documents for the Lender
         Liens and agrees that any action taken by Administrative Agent
         concerning any Collateral (with the consent or at the request of
         Required Lenders) in accordance with any Credit Document, that
         Administrative Agent's exercise (with the consent or at the request of
         Required Lenders) of powers concerning the Collateral in any Credit
         Document and that all other reasonably incidental powers are authorized
         and binding upon all Lenders.

                  (b) Maintaining Lender Liens. Administrative Agent is
         authorized on behalf of all Lenders, without the necessity of any
         notice to or further consent from any Lender, from time to time before
         an Event of Default or Potential Default, to take any action with
         respect to any Collateral or Credit Documents related to Collateral
         that may be necessary to perfect and maintain perfected the Lender
         Liens upon the Collateral.

                  (c) Limitation of Obligations. Except to use the same standard
         of care that it ordinarily uses for collateral for its sole benefit,
         Administrative Agent has no obligation whatsoever to any Lender or to
         any other Person to assure that the Collateral exists or is owned by
         any Company or is cared for, protected, or insured or has been
         encumbered or that the Lender Liens have been properly or sufficiently
         or lawfully created, perfected, protected, or enforced or are entitled
         to any particular priority.

                  (d) Standard of Care. Administrative Agent shall exercise the
         same care and prudent judgment with respect to the Collateral and the
         Credit Documents as it normally and customarily exercises in respect of
         similar collateral and security documents.

                  (e) Release of Collateral. Lenders irrevocably authorize
         Administrative Agent, at its option and in its discretion, to release
         any Lender Lien upon any Collateral (i) upon full payment of the
         Obligation, (ii) constituting property being disposed of as permitted
         under any Credit Document, (iii) constituting property in which no
         Company owned any interest at the time the Lender Lien was granted or
         at any time after that, (iv) constituting property leased to any
         Company under a lease that has expired or been terminated in a
         transaction permitted under the Credit Documents or is about to expire
         and that has not been, and is not intended by that Company to be,
         renewed, (v) consisting of an instrument evidencing Debt pledged to
         Administrative Agent (for the benefit of Lenders), if the underlying
         Debt has been paid in full, or (vi) if approved, authorized, or
         ratified in writing by Lenders. Upon request



                                       52
<PAGE>   58

         by Administrative Agent at any time, Lenders shall confirm in writing
         Administrative Agent's authority to release particular types or items
         of Collateral under this CLAUSE (e).

         13.8 Limitation of Liability. No Lender or any Participant will incur
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither Administrative Agent nor any Lender or Participant will
incur any liability to any other Person for any act or omission of any other
Lender or any Participant.

         13.9 Relationship of Lenders. The Credit Documents do not create a
partnership or joint venture among Administrative Agent and Lenders or among
Lenders.

         13.10 Benefits of Agreement. None of the provisions of this section
inure to the benefit of any Company or any other Person except Administrative
Agent and Lenders. Therefore, no Company or any other Person is entitled to rely
upon, or entitled to raise as a defense, in any manner whatsoever, the failure
of Administrative Agent or any Lender to comply with these provisions.

SECTION 14. MISCELLANEOUS.

         14.1 Nonbusiness Days. Any payment or action that is due under any
Credit Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a LIBOR Rate
Borrowing, in which case if the next-succeeding Business Day is in the next
calendar month, then such payment shall be made on the next-preceding Business
Day.

         14.2 Communications. Unless otherwise specifically provided, whenever
any Credit Document requires or permits any consent, approval, notice, request
or demand from one party to another, communication must be in writing (which may
be by telex or fax) to be effective and shall be deemed to have been given (i)
if by telex, when transmitted to the appropriate telex number and the
appropriate answer back is received, (ii) if by fax, when transmitted to the
appropriate fax number (and all communications sent by fax must be confirmed
promptly thereafter by telephone; but any requirement in this parenthetical
shall not affect the date when the fax shall be deemed to have been delivered),
(iii) if by mail, on the third Business Day after it is enclosed in an envelope
and properly addressed, stamped, sealed and deposited in the appropriate
official postal service, or (iv) if by any other means, when actually delivered.
Until changed by notice pursuant to this agreement, the address (and fax number)
for Administrative Agent, each initial Lender and Borrower is stated beside
their respective signatures to this agreement. The address (and fax number) for
each Lender who becomes party to this agreement after the Closing Date shall be
stated beside its name on the then most recently amended SCHEDULE 2.

         14.3 Form and Number of Documents. The form, substance and number of
counterparts of each writing to be furnished under this agreement must be
reasonably satisfactory to Administrative Agent and its counsel.

         14.4 Exceptions to Covenants. No Company may take or fail to take any
action that is permitted as an exception to any of the covenants contained in
any Credit Document if that action or omission would result in the breach of any
other covenant contained in any Credit Document.

        14.5 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Credit Documents survive all
closings under the Credit Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

         14.6 Governing Governmental Requirements. Unless otherwise stated in
any Credit Document, the Governmental Requirements of the State of Texas and of
the United States of America govern the Rights and



                                       53
<PAGE>   59


duties of the parties to the Credit Documents and the validity, construction,
enforcement, and interpretation of the Credit Documents.

         14.7 Invalid Provisions. Any provision in any Credit Document held to
be illegal, invalid or unenforceable is fully severable; the appropriate Credit
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. Administrative Agent, Lenders
and each Company party to the affected Credit Document agree to negotiate, in
good faith, the terms of a replacement provision as similar to the severed
provision as may be possible and be legal, valid and enforceable.

         14.8 Conflicts Between Credit Documents. The provisions of this
agreement control if in conflict (i.e., the provisions contradict each other as
opposed to a Credit Document containing additional provisions not in conflict)
with the provisions of any other Credit Document.

         14.9 Discharge and Certain Reinstatement. Borrower's obligations under
the Credit Documents remain in full force and effect until Lenders have no
commitment to extend credit under the Credit Documents and the Obligation is
fully paid (except for provisions under the Credit Documents which by their
terms expressly survive payment of the Obligation and termination of the Credit
Documents). If any payment under any Credit Document is ever rescinded or must
be restored or returned for any reason, then all Rights and obligations under
the Credit Documents in respect of that payment are automatically reinstated as
though the payment had not been made when due.

         14.10 Amendments, Consents, Conflicts, and Waivers.

                  (a) Required Lenders. Unless otherwise specifically provided
         (i) the provisions of this agreement may be amended, modified, or
         waived, only by an instrument in writing executed by Borrower,
         Administrative Agent, and Required Lenders and supplemented only by
         documents delivered or to be delivered in accordance with the express
         terms of this agreement, and (ii) the other Credit Documents may only
         be the subject of an amendment, modification, or waiver that has been
         approved by Required Lenders and Borrower.

                  (b) All Lenders. Any amendment to or consent or waiver under
         this agreement or any Credit Document that purports to accomplish any
         of the following must be by an instrument in writing executed by
         Borrower and Administrative Agent and executed (or approved, as the
         case may be) by each Lender: (i) Extends the due date or decreases the
         amount of any scheduled payment or amortization of the Obligation
         beyond the date specified in the Credit Documents; (ii) decreases any
         rate or amount of interest, fees, or other sums payable to
         Administrative Agent or Lenders under this agreement (except such
         reductions as are contemplated by this agreement); (iii) changes the
         definition of "COMMITMENT," "COMMITMENT PERCENTAGE," "REQUIRED
         LENDERS," or "PRO RATA PART;" (iv) increases any one or more Lenders'
         Commitment; (v) waives compliance with, amends, or fully or partially
         releases -- except as expressly provided in the Credit Documents or for
         when a Company merges into another Person or dissolves when
         specifically permitted in the Credit Documents -- any Guaranty or
         Collateral; or (vi) changes this CLAUSE (b) or any other matter
         specifically requiring the consent of all Lenders under this agreement.

                  (c) Conflicts. Any conflict or ambiguity between the terms and
         provisions of this agreement and terms and provisions in any other
         Credit Document is controlled by the terms and provisions of this
         agreement.

                  (d) Waivers. No course of dealing or any failure or delay by
         Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of Administrative
         Agent or any Lender under this agreement operates as a waiver thereof.
         A waiver must



                                       54
<PAGE>   60

         be in writing and signed by Administrative Agent and Lenders (or
         Required Lenders, if permitted under this agreement) to be effective,
         and a waiver will be effective only in the specific instance and for
         the specific purpose for which it is given.

         14.11 Multiple Counterparts. Any Credit Document may be executed in a
number of identical counterparts, and by each party thereto on separate
counterparts (including, at Administrative Agent's discretion, counterparts or
signature pages executed and transmitted by fax) with the same effect as if all
signatories had signed the same document. All counterparts must be construed
together to constitute one and the same instrument.

         14.12 Parties.

                  (a) Parties Bound. Each Credit Document binds and inures to
         the parties to it, any intended beneficiary of it, and each of their
         respective successors and permitted assigns. No Company may assign or
         transfer any Rights or obligations under any Credit Document without
         first obtaining all Lenders' consent, and any purported assignment or
         transfer without such consent is void. No Lender may transfer, pledge,
         assign, sell any participation in, or otherwise encumber its portion of
         the Obligation except as permitted by CLAUSES (b) or (c) below.

                  (b) Participations. Any Lender may (subject to the provisions
         of this section, in accordance with applicable Governmental
         Requirements, in the ordinary course of its business, and at any time)
         sell to one or more Persons (each a "PARTICIPANT") participating
         interests in its portion of the Obligation. The selling Lender remains
         a "Lender" under the Credit Documents, the Participant does not become
         a "Lender" under the Credit Documents, and the selling Lender's
         obligations under the Credit Documents remain unchanged. The selling
         Lender remains solely responsible for the performance of its
         obligations and remains the holder of its share of the Principal Debt
         for all purposes under the Credit Documents. Borrower and
         Administrative Agent shall continue to deal solely and directly with
         the selling Lender in connection with that Lender's Rights and
         obligations under the Credit Documents, and each Lender must retain the
         sole right and responsibility to enforce due obligations of the
         Companies. Participants have no Rights under the Credit Documents
         except certain voting rights as provided below. Subject to the
         following, each Lender may obtain (on behalf of its Participants) the
         benefits of SECTION 3 with respect to all participations in its part of
         the Obligation outstanding from time to time so long as Borrower is not
         obligated to pay any amount in excess of the amount that would be due
         to that Lender under SECTION 3 calculated as though no participations
         have been made. No Lender may sell any participating interest under
         which the Participant has any Rights to approve any amendment,
         modification, or waiver of any Credit Document except as to matters in
         SECTION 14.10(b)(i) and (ii).

                  (c) Assignments. Each Lender may make assignments to the
         Federal Reserve Bank. Each Lender may also assign to one or more
         assignees (each an "ASSIGNEE") all or any part of its Rights and
         obligations under the Credit Documents so long as (i) the assignor
         Lender and Assignee execute and deliver to Administrative Agent and
         Borrower for their consent and acceptance (that may not be unreasonably
         withheld in any instance and is not required if the Assignee is an
         Affiliate of the assigning Lender) an assignment and assumption
         agreement in substantially the form of EXHIBIT K (an "ASSIGNMENT") and
         pay to Administrative Agent a processing fee of $2,500, (ii) the
         assignment is for an identical percentage of the assignor Lender's
         Rights and obligations under the Term Loan and the Revolving Facility,
         (iii) the assignment must be for a minimum total Commitment of
         $5,000,000 and, if the assigning Lender retains any Commitment, it must
         be a minimum total Commitment of $5,000,000, and (iv) the conditions
         for that assignment set forth in the applicable Assignment are
         satisfied. The "Effective Date" in each Assignment must (unless a
         shorter period is agreeable to Borrower and Administrative Agent) be at
         least five Business Days after it is executed and delivered by the
         assignor Lender and the Assignee to Administrative Agent and Borrower
         for acceptance. Once



                                       55
<PAGE>   61

         that Assignment is accepted by Administrative Agent and Borrower, and
         subject to all of the following occurring, then, on and after the
         "Effective Date" stated in it (i) the Assignee automatically becomes a
         party to this agreement and, to the extent provided in that Assignment,
         has the Rights and obligations of a Lender under the Credit Documents,
         (ii) the assignor Lender, to the extent provided in that Assignment, is
         released from its obligations to fund Borrowings under this agreement
         and its reimbursement obligations under this agreement and, in the case
         of an Assignment covering all of the remaining portion of the assignor
         Lender's Rights and obligations under the Credit Documents, that Lender
         ceases to be a party to the Credit Documents, (iii) Borrower shall
         execute and deliver to the assignor Lender and the Assignee the
         appropriate Notes in accordance with this agreement following the
         transfer, (iv) upon delivery of the Notes under CLAUSE (iii) preceding,
         the assignor Lender shall return to Borrower all Notes previously
         delivered to that Lender under this agreement, and (v) SCHEDULE 2 is
         automatically deemed to be amended to reflect the name, address,
         telecopy number, and Commitment of the Assignee and the remaining
         Commitment (if any) of the assignor Lender, and Administrative Agent
         shall prepare and circulate to Borrower and Lenders an amended SCHEDULE
         2 reflecting those changes.

         14.13 Venue, Service of Process, and Jury Trial. BORROWER AND (PURSUANT
TO ITS GUARANTY OR ITS EXECUTION AND DELIVERY OF, OR CONSENT TO, ANY OTHER
CREDIT DOCUMENT) EACH COMPANY, IN EACH CASE FOR ITSELF AND ITS SUCCESSORS AND
ASSIGNS, IRREVOCABLY (a) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE
AND FEDERAL COURTS IN TEXAS, (b) WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE GOVERNMENTAL REQUIREMENTS, ANY OBJECTION THAT IT MAY NOW OR IN THE
FUTURE HAVE TO THE LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN
CONNECTION WITH ANY CREDIT DOCUMENT AND THE OBLIGATION BROUGHT IN THE DISTRICT
COURTS OF DALLAS COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE
NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, (c) WAIVES ANY CLAIMS THAT ANY
LITIGATION BROUGHT IN ANY OF THE FOREGOING COURTS HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM, (d) CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THOSE
COURTS IN ANY LITIGATION BY THE MAILING OF COPIES OF THAT PROCESS BY CERTIFIED
MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND DELIVERY, OR BY
DELIVERY BY A NATIONALLY RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE DEEMED
COMPLETE UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS FOR PURPOSES OF THIS
AGREEMENT, (e) AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY CREDIT
DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE CREDIT DOCUMENTS OR THE
OBLIGATION MAY BE BROUGHT IN ONE OF THE FOREGOING COURTS, AND (f) WAIVES TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE GOVERNMENTAL REQUIREMENTS, ITS RESPECTIVE
RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT
OF ANY CREDIT DOCUMENT. The scope of each of the foregoing waivers is intended
to be all encompassing of any and all disputes that may be filed in any court
and that relate to the subject matter of this transaction, including, without
limitation, contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims. BORROWER AND (PURSUANT TO ITS GUARANTY OR ITS
EXECUTION AND DELIVERY OF, OR CONSENT TO, ANY OTHER CREDIT DOCUMENT) EACH OTHER
COMPANY ACKNOWLEDGES THAT THESE WAIVERS ARE A MATERIAL INDUCEMENT TO
ADMINISTRATIVE AGENT'S AND EACH LENDER'S AGREEMENT TO ENTER INTO A BUSINESS
RELATIONSHIP, THAT ADMINISTRATIVE AGENT AND EACH LENDER HAS ALREADY RELIED ON
THESE WAIVERS IN ENTERING INTO THIS AGREEMENT, AND THAT ADMINISTRATIVE AGENT AND
EACH LENDER WILL CONTINUE TO RELY ON EACH OF THESE WAIVERS IN RELATED FUTURE
DEALINGS. BORROWER AND (PURSUANT TO ITS GUARANTY OR ITS EXECUTION AND DELIVERY
OF, OR CONSENT TO, ANY OTHER CREDIT DOCUMENT) EACH OTHER COMPANY FURTHER
WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THESE WAIVERS WITH ITS LEGAL
COUNSEL, AND THAT IT KNOWINGLY AND VOLUNTARILY AGREES TO EACH WAIVER FOLLOWING
CONSULTATION WITH LEGAL COUNSEL. The waivers in this section are irrevocable,
meaning that they may not be modified either orally or in writing, and these
waivers apply to any future renewals, extensions, amendments, modifications, or
replacements in respect of the applicable Credit Document. In connection with
any Litigation, this agreement may be filed as a written consent to a trial by
the court.

                                   TERM NOTE

$__________________                                           February 16, 1999

         FOR VALUE RECEIVED, the undersigned, ULTRAK, INC., a Delaware
corporation ("BORROWER"), irrevocably and unconditionally promises to pay to the
order of __________________, a __________________ ("LENDER", and together with
each subsequent holder hereof, "PAYEE"), at the principal banking office of
Administrative Agent (hereinafter referenced) at 1717 Main Street, Dallas, Texas
75201 (i) the principal amount of ___________________ AND NO/100 DOLLARS
($___________________) in installments on the dates and in the principal amounts
provided for in the Credit Agreement hereinafter referenced, and (ii) interest
on the unpaid principal amount of this Note from time to time remaining
outstanding and unpaid from the date hereof until it shall be paid in full, at
the rates per annum and on the dates provided in the Credit Agreement.

         All capitalized terms used herein and not otherwise defined herein
shall have the same meaning and effect as used and defined in that certain
Credit Agreement dated as of February 16, 1999 (as amended and otherwise
modified, and in effect, the "CREDIT AGREEMENT"), by and between Borrower,
certain Lenders, and Bank One Texas, N.A., as Administrative Agent for those
Lenders. Reference is hereby made to the Credit Agreement for all intents and
purposes.

         This Note is a "Term Note" executed by Borrower and is referred to in,
governed by, and subject to, and is entitled to the benefits of, the terms and
provisions of the Credit Agreement as therein stated and referenced. Reference
is hereby made to the Credit Agreement for a statement of the agreements,
rights, remedies, benefits and obligations of Payee and the covenants,
agreements, rights, duties and obligations of Borrower in relation hereto,
including provisions for acceleration of the maturity hereof, interest rate and
amount limitations, voluntary and mandatory prepayments and scheduled payments
hereon; but this reference to the Credit Agreement, or any provision thereof,
shall not affect or impair the irrevocable, absolute and unconditional
obligation of Borrower to pay principal of, and interest on, this Note when due.
Unless the maturity of this Note shall have sooner occurred, the outstanding
principal balance of this Note and all accrued and unpaid interest thereon shall
be finally and fully payable on February 16, 2002.

         The date, amount, Type, and interest rate and duration of each
Borrowing made by Lender to Borrower, and each payment made on account of the
principal thereof, and accrued interest thereon, shall be recorded by Payee on
its books and records, and prior to any transfer of this Note, endorsed by Payee
on a schedule attached hereto or any continuation thereof; and all recordations
and endorsements made by Payee shall, absent manifest error, be conclusive of
all such matters and binding on all Persons. Payee's failure to make or error in
making any such recordations or endorsements shall not diminish, reduce or
relieve Borrower's obligation to pay (i) all Borrowings made by Lender to
Borrower and then outstanding and (ii) all accrued and earned interest on the
amounts thereof from time to time outstanding and unpaid, pursuant to this Note.

         Upon the occurrence of an Event of Default, this Note may be declared
to be, or shall become, forthwith due and immediately payable in the manner,
upon the conditions and with the effect, provided for and referred to in the
Credit Agreement.

         If this Note is placed in the hands of an attorney for collection
(whether or not any proceeding is filed in connection therewith), or collected
through suit, the Bankruptcy Court or any other judicial proceeding, Borrower
irrevocably and unconditionally agrees to pay all costs, expenses and fees
incurred by Payee, including reasonable attorneys' fees and expenses, and any
assessed court and related costs, in addition to all other amounts owing
hereunder.

                                 REVOLVING NOTE


$_____________                                                  February 16,1999

         FOR VALUE RECEIVED, the undersigned, ULTRAK, INC., a Delaware
corporation ("BORROWER"), irrevocably and unconditionally promises to pay to the
order of ________________, a ___________________ ("LENDER", and together with
each subsequent holder hereof, "PAYEE"), at the principal banking office of
Administrative Agent (hereinafter referenced) at 1717 Main Street, Dallas, Texas
75201, (i) the principal amount of ___________________ AND NO/100 DOLLARS
($_________________) (or such lesser amount as shall equal the aggregate unpaid
principal amount of all Revolving Facility Borrowings made by Lender to Borrower
pursuant to the Credit Agreement hereinafter referenced), on the dates and in
the principal amounts provided for in the Credit Agreement, and (ii) interest on
the unpaid principal amount of each such Revolving Facility Borrowing from time
to time remaining outstanding and unpaid from the date of each such Revolving
Facility Borrowing until it shall be paid in full, at the rates per annum and on
the dates provided for in the Credit Agreement.

         All capitalized terms used herein and not otherwise defined herein
shall have the same meaning and effect as used and defined in that certain
Credit Agreement dated as of February 16, 1999 (as amended and otherwise
modified, and in effect, the "CREDIT AGREEMENT"), by and between Borrower,
certain Lenders, and Bank One Texas, N.A., as Administrative Agent for those
Lenders. Reference is hereby made to the Credit Agreement for all intents and
purposes.

         This Note is a "Revolving Note" executed by Borrower and is referred to

and provisions of the Credit Agreement as therein stated and referenced.
Reference is hereby made to the Credit Agreement for a statement of the
agreements, rights, remedies, benefits and obligations of Payee and the
covenants, agreements, rights, duties and obligations of Borrower in relation
hereto, including provisions for acceleration of the maturity hereof, interest
rate and amount limitations and voluntary and mandatory prepayments hereon; but
this reference to the Credit Agreement, or any provision thereof, shall not

all such matters and binding on all Persons. Payee's failure to make or error in
making any such recordations or endorsements shall not diminish, reduce or
relieve Borrower's obligation to pay (i) all Revolving Facility Borrowings made
by Lender and then outstanding and (ii) all accrued and earned interest on the
amounts thereof from time to time outstanding and unpaid, pursuant to this Note.

         Upon the occurrence of an Event of Default, this Note may be declared

                               GUARANTY AGREEMENT


         WHEREAS, ULTRAK, INC., a Delaware corporation ("BORROWER"), has entered
into a Credit Agreement of even date herewith with certain lenders which are or
may from time to time become parties thereto (each a "LENDER" and collectively,
"LENDERS"), and BANK ONE, TEXAS, N.A., a national banking association, as
administrative agent for itself and the other Lenders (in such capacity,
together with its successors in such capacity, "ADMINISTRATIVE AGENT"), pursuant
to which Lenders have agreed to make available (a) a revolving credit facility
to Borrower with advances thereunder not to exceed an aggregate principal amount
of $30,000,000 at any time outstanding, and (b) a term loan to Borrower in the
principal amount of $20,000,000 (such Credit Agreement, as may be amended,
extended, restated, supplemented or modified from time to time, the "CREDIT
AGREEMENT"); terms defined in the Credit Agreement and not otherwise defined
herein are used herein as defined therein; and

         WHEREAS, Administrative Agent and Lenders have conditioned their
obligations under the Credit Agreement upon the execution and delivery by
Guarantor (hereinafter defined) of this Guaranty Agreement (this "GUARANTY");

         NOW, THEREFORE, for valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the undersigned, ___________________, a
____________ corporation ("GUARANTOR"), hereby irrevocably and unconditionally
guarantees to Administrative Agent and Lenders, the full and prompt payment and
performance of the Guaranteed Indebtedness (hereinafter defined), this Guaranty
being upon the following terms:

         1. The term "GUARANTEED INDEBTEDNESS", as used herein means all of the
Obligation and shall include any and all post-petition interest and expenses
(including reasonable attorneys' fees) whether or not allowed under any
bankruptcy, insolvency, or other similar law.

         2. This Guaranty shall be an absolute, continuing, irrevocable, and
unconditional guaranty of payment and performance, and not a guaranty of
collection, and Guarantor shall remain liable on its obligations hereunder until
the payment and performance in full of the Guaranteed Indebtedness and
termination of the Commitments. No set-off, counterclaim, recoupment, reduction,
or diminution of any obligation, or any defense of any kind or nature which
Borrower may have against Administrative Agent, any Lender or any other party,
or which Guarantor may have against Borrower or any other party (other than
Administrative Agent or any Lender), shall be available to, or shall be asserted
by, Guarantor against Administrative Agent, any Lender or any subsequent holder
of the Guaranteed Indebtedness or any part thereof or against payment of the
Guaranteed Indebtedness or any part thereof.

         3. It is the intention of Guarantor, Administrative Agent and Lenders
that the amount of the Guaranteed Indebtedness not exceed the maximum amount
permitted by applicable laws, including fraudulent conveyance, fraudulent
transfer or similar laws applicable to Guarantor. Accordingly, and
notwithstanding anything to the contrary in this Guaranty, any Credit Document,
or any other agreement or instrument executed in connection with the payment of
any of the Guaranteed Indebtedness, if, after giving effect to this Guaranty and
applicable laws, the obligations of Guarantor under this Guaranty would
otherwise be set aside, terminated, annulled or avoided for such reason by a
court of competent jurisdiction in a proceeding actually pending before such
court, the amount of the Guaranteed Indebtedness shall be limited to the maximum
amount permitted by applicable laws which would not (a) render Guarantor
insolvent, (b) result in the fair saleable value of Guarantor's assets being
less than the amount required to pay its debts and other liabilities (including
contingent liabilities) as they mature, or (c) leave Guarantor with unreasonably
small capital to carry out its business as conducted prior to the execution of
this Guaranty and as proposed to be conducted, including its capital needs.



                                       1

         4. If Guarantor becomes liable for any indebtedness owing by Borrower
to Administrative Agent or any Lender by endorsement or otherwise, other than
under this Guaranty, such liability shall not be in any manner impaired or
affected hereby, and the rights of Administrative Agent and Lenders hereunder
shall be cumulative of any and all other rights that Administrative Agent and
Lenders may ever have against Guarantor. The exercise by Administrative Agent or
any Lender of any right or remedy hereunder or under any other instrument, or at
law or in equity, shall not preclude the concurrent or subsequent exercise of
any other right or remedy.

         5. In the event of default by Borrower in payment or performance of the
Guaranteed Indebtedness, or any part thereof, when such Guaranteed Indebtedness
becomes due, whether by its terms, by acceleration, or otherwise, Guarantor
shall promptly pay the amount due thereon to Administrative Agent, for the
benefit of Lenders, upon demand in lawful currency of the United States of
America and it shall not be necessary for Administrative Agent, in order to
enforce such payment by Guarantor, first to institute suit or exhaust its
remedies against Borrower or others liable on such Guaranteed Indebtedness, or
to enforce any rights against any collateral which shall ever have been given to
secure such Guaranteed Indebtedness.

         6. If acceleration of the time for payment of any amount payable by
Borrower under the Guaranteed Indebtedness is stayed upon the insolvency,
bankruptcy, or reorganization of Borrower or otherwise, all such amounts
otherwise subject to acceleration under the terms of the Guaranteed Indebtedness
shall nonetheless be payable by Guarantor hereunder forthwith on demand by
Administrative Agent.

         7. Guarantor hereby agrees that its obligations under this Guaranty
shall not be released, discharged, diminished, impaired, reduced, or affected
for any reason or by the occurrence of any event, including, without limitation,
one or more of the following events, whether or not with notice to or the
consent of Guarantor: (a) the taking or accepting of collateral as security for
any or all of the Guaranteed Indebtedness or the sale, release, surrender,
exchange, or subordination of any collateral now or hereafter securing any or
all of the Guaranteed Indebtedness; (b) any partial release of the liability of
Guarantor hereunder, or the full or partial release of Borrower or any other
guarantor from liability for any or all of the Guaranteed Indebtedness; (c) the
dissolution, insolvency, or bankruptcy of Borrower, Guarantor, or any other
party at any time liable for the payment of any or all of the Guaranteed
Indebtedness; (d) any renewal, extension, modification, waiver, amendment, or
rearrangement of any or all of the Guaranteed Indebtedness or any instrument,
document, or agreement evidencing, securing, or otherwise relating to any or all
of the Guaranteed Indebtedness; (e) any adjustment, indulgence, forbearance,
waiver, settlement, or compromise that may be granted or given by Administrative
Agent or any Lender to Borrower, Guarantor, or any other party ever liable for
any or all of the Guaranteed Indebtedness; (f) the subordination of the payment
of all or any part of the Guaranteed Indebtedness to the payment of any
obligations, indebtedness, or liabilities which may be due or become due to
Administrative Agent, any Lender or others; (g) the application of any deposit
balance, fund, payment, collections through process of law or otherwise, or
other collateral of Borrower to the satisfaction and liquidation of the
indebtedness or obligations of Borrower to Administrative Agent or any Lender,
if any, not guaranteed under this Guaranty; (h) the application of any sums paid
to Administrative Agent or any Lender by Guarantor, any other guarantor of all
or any part of the Guaranteed Indebtedness, Borrower or others to the Guaranteed
Indebtedness in such order and manner as Administrative Agent may determine in
accordance with the Credit Agreement; (i) any neglect, delay, omission, failure,
or refusal of Administrative Agent or any Lender to take or prosecute any action
for the collection of any of the Guaranteed Indebtedness or to foreclose or take
or prosecute any action in connection with any instrument, document, or
agreement evidencing, securing, or otherwise relating to any or all of the
Guaranteed Indebtedness; (j) the unenforceability or invalidity of any or all of
the Guaranteed Indebtedness or of any instrument, document, or agreement
evidencing, securing, or otherwise relating to any or all of the Guaranteed
Indebtedness; (k) any payment by Borrower or any other party to Administrative
Agent or any Lender is held to constitute a preference under applicable
bankruptcy or insolvency law or if for any other reason Administrative Agent or
any Lender is required to refund any payment or pay the amount thereof to
someone else; (l) the settlement or compromise of any of the Guaranteed
Indebtedness; (m) the non-perfection of any security interest or lien securing
any or all of the Guaranteed Indebtedness; (n) any impairment of any collateral
securing any or all of the Guaranteed Indebtedness; (o) the failure of
Administrative Agent or any Lender to sell any collateral



                                       2
<PAGE>   76



securing any or all of the Guaranteed Indebtedness in a commercially reasonable
manner or as otherwise required by law; (p) any change in the corporate
existence, structure, or ownership of Borrower; (q) any other circumstance which
might otherwise constitute a defense available to, or discharge of, Borrower;
(r) the unenforceability of all or an part of the Guaranteed Indebtedness
against Borrower by reason of the fact that the Guaranteed Indebtedness exceeds
the amount permitted by law; (s) the act of creating all or any part of the
Guaranteed Indebtedness is ultra vires; or (t) the officers creating all or any
part of the Guaranteed Indebtedness acted in excess of their authority.

         8. Guarantor hereby represents and warrants to Administrative Agent and
Lenders the following:

                  (a) This Guaranty may reasonably be expected to benefit,
         directly or indirectly, Guarantor.

                  (b) Guarantor is familiar with, and has independently reviewed
         the books and records regarding, the financial condition of Borrower
         and is familiar with the value of any and all collateral intended to be
         security for the payment of all or any part of the Guaranteed
         Indebtedness. However, Guarantor is not relying on such financial
         condition or collateral as an inducement to enter into this Guaranty.

                  (c) Guarantor has adequate means to obtain from Borrower on a
         continuing basis information concerning the financial condition of
         Borrower, and Guarantor is not relying on Administrative Agent or the
         Lenders to provide such information to Guarantor either now or in the
         future.

                  (d) Guarantor has the power and authority to execute, deliver,
         and perform this Guaranty and any other agreements executed by
         Guarantor contemporaneously herewith, and the execution, delivery, and
         performance of this Guaranty and any other agreements executed by
         Guarantor contemporaneously herewith do not and will not violate (i)
         any agreement or instrument to which Guarantor is a party, or (ii) any
         law, rule, regulation, or order of any Governmental Authority to which
         Guarantor is subject.

                  (e) Neither Administrative Agent, Lenders, nor any other party
         has made any representation, warranty, or statement to Guarantor in
         order to induce Guarantor to execute this Guaranty.

                  (f) The financial statements and other financial information
         regarding Guarantor heretofore and hereafter delivered to
         Administrative Agent and any Lender are and shall be true and correct
         in all material respects and fairly present the financial position of
         Guarantor as of the dates thereof, and no material adverse change has
         occurred in the financial condition of Guarantor as reflected in those
         financial disclosures.

                  (g) As of the date hereof, and after giving effect to this
         Guaranty, including without limitation, all rights of contribution and
         subrogation, and the obligations evidenced hereby, Guarantor is and
         will be Solvent (to the extent necessary, taking into account any
         rights of contribution, reimbursement and subrogation).

                  (h) All representations and warranties about Guarantor made in
         the Credit Agreement are true and correct.

                  (i) This Guaranty is the legal and binding obligation of
         Guarantor, enforceable in accordance with its terms, except as limited
         by bankruptcy, insolvency or other laws of general application relating
         to the enforcement of creditors' rights.




                                       3
<PAGE>   77


         9. Guarantor covenants and agrees that, as long as the Guaranteed
Indebtedness or any part thereof is outstanding or Lender has any Commitment
under the Credit Agreement:

                  (a) Guarantor shall not, so long as its obligations under this
         Guaranty continue, transfer or pledge any material portion of its
         assets for less than full and adequate consideration; provided that,
         Guarantor may make Distributions to Borrower as contemplated by SECTION
         9.8 of the Credit Agreement.

                  (b) Guarantor shall promptly furnish to Administrative Agent
         at any time and from time to time such financial statements and other
         financial information as Administrative Agent may require, in form and
         substance reasonably satisfactory to Administrative Agent.

                  (c) Guarantor acknowledges that certain covenants and other
         provisions in the Credit Agreement are applicable to it or are imposed
         upon it and agrees to promptly and properly comply with or be bound by
         each of them.

                  (d) Guarantor shall promptly inform Administrative Agent of
         (i) any litigation or governmental investigation against Guarantor or
         affecting any security for all or any part of the Guaranteed
         Indebtedness or this Guaranty which, if determined adversely, might
         have a material adverse effect upon the financial condition of
         Guarantor or upon such security or might cause a default under any of
         the Credit Documents, (ii) any claim or controversy which might become
         the subject of such litigation or governmental investigation, and (iii)
         any material adverse change in the financial condition of Guarantor.

         10. (a) Guarantor hereby agrees that the Subordinated Indebtedness
(hereinafter defined) shall be subordinate and junior in right of payment to the
prior payment in full of all Guaranteed Indebtedness, and Guarantor hereby
assigns the Subordinated Indebtedness to Administrative Agent, for the benefit
of Lenders, as security for the Guaranteed Indebtedness. If any sums shall be
paid to Guarantor by Borrower or any other person or entity on account of the
Subordinated Indebtedness, such sums shall be held in trust by Guarantor for the
benefit of Administrative Agent and shall forthwith be paid to Administrative
Agent without affecting the liability of Guarantor under this Guaranty and may
be applied by Administrative Agent and Lenders against the Guaranteed
Indebtedness in the order and manner described in SECTION 3.11 of the Credit
Agreement. Upon the request of Administrative Agent, Guarantor shall execute,
deliver, and endorse to Administrative Agent such documents and instruments as
Administrative Agent may request to perfect, preserve, and enforce its rights
hereunder. For purposes of this Guaranty, the term "SUBORDINATED INDEBTEDNESS"
means all indebtedness, liabilities, and obligations of Borrower to Guarantor,
whether such indebtedness, liabilities, and obligations now exist or are
hereafter incurred or arise, or whether the obligations of Borrower thereon are
direct, indirect, contingent, primary, secondary, several, joint and several, or
otherwise, and irrespective of whether such indebtedness, liabilities, or
obligations are evidenced by a note, contract, open account, or otherwise, and
irrespective of the person or persons in whose favor such indebtedness,
obligations, or liabilities may, at their inception, have been, or may hereafter
be created, or the manner in which they have been or may hereafter be acquired
by Guarantor.

<PAGE>   78


              (b) Guarantor agrees that any and all liens, security interests,
judgment liens, charges, or other encumbrances upon Borrower's assets securing
payment of any Subordinated Indebtedness shall be and remain inferior and
subordinate to any and all liens, security interests, judgment liens, charges,
or other encumbrances upon Borrower's assets securing payment of the Guaranteed
Indebtedness or any part thereof, regardless of whether such encumbrances in
favor of Guarantor or Administrative Agent presently exist or are hereafter
created or attached. Without the prior written consent of Required Lenders,
Guarantor shall not (i) file suit against Borrower or exercise or enforce any
other creditor's right it may have against Borrower, or (ii) foreclose,
repossess, sequester, or otherwise take steps or institute any action or
proceedings, judicial or otherwise, including without limitation the
commencement of, or joinder in, any liquidation, bankruptcy, rearrangement,
debtor's relief or insolvency proceeding to enforce any liens, security
interests, collateral rights, judgments or other encumbrances held by Guarantor
on assets of Borrower.

              (c) In the event of any receivership, bankruptcy, reorganization,
rearrangement, debtor's relief, or other insolvency proceeding involving
Borrower as debtor, Administrative Agent shall have the right to prove and vote
any claim under the Subordinated Indebtedness and to receive directly from the
receiver, trustee or other court custodian all dividends, distributions, and
payments made in respect of the Subordinated Indebtedness. Administrative Agent
may apply such dividends, distributions, and payments against the Guaranteed
Indebtedness in such order and manner as Administrative Agent and Lenders may
determine in their sole discretion.

              (d) Guarantor agrees that all promissory notes, accounts
receivable, ledgers, records, or any other evidence of Subordinated Indebtedness
shall contain a specific written notice thereon that the indebtedness evidenced
thereby is subordinated under the terms of this Guaranty.

         11. Guarantor waives (a) promptness, diligence, and notice of
acceptance of this Guaranty and notice of the incurring of any obligation,
indebtedness, or liability to which this Guaranty applies or may apply and
waives presentment for payment, notice of nonpayment, protest, demand, notice of
protest, notice of intent to accelerate, notice of acceleration, notice of
dishonor, diligence in enforcement, and indulgences of every kind, and (b) the
taking of any other action by Administrative Agent, including without
limitation, giving any notice of default or any other notice to, or making any
demand on, Borrower, any other guarantor of all or any part of the Guaranteed
Indebtedness or any other party.

         12. In addition to any other waivers, agreements and covenants of
Guarantor set forth herein, Guarantor hereby further waives and releases all
claims, causes of action, defenses and offsets for any act or omission of
Administrative Agent, its directors, officers, employees, representatives,
counsel or agents in connection with (i) Administrative Agent's or such other
parties' administration of the Guaranteed Indebtedness or (ii) Administrative
Agent's or such other parties' ordinary negligence, but not including (iii)
Administrative Agent's or such other parties' willful misconduct and gross
negligence.

         13. This Guaranty shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of all or any part of the Guaranteed
Indebtedness is rescinded or must otherwise be returned by Administrative Agent
or any Lender upon the insolvency, bankruptcy, or reorganization of Borrower,
Guarantor, any other guarantor of all or any part of the Guaranteed
Indebtedness, or otherwise, all as though such payment had not been made.

         14. Any acknowledgment or new promise, whether by payment of principal
or interest or otherwise and whether by Borrower or others (including
Guarantor), with respect to any of the Guaranteed Indebtedness shall, if the
statute of limitations in favor of Guarantor against Administrative Agent or any
Lender shall have commenced to run, toll the running of such statute of
limitations and, if the period of such statute of limitations shall have
expired, prevent the operation of such statute of limitations.

         15. This Guaranty is for the benefit of Administrative Agent and
Lenders and their respective successors and assigns, and in the event of an
assignment of the Guaranteed Indebtedness, or any part thereof, the rights and
benefits hereunder, to the extent applicable to the indebtedness so assigned,
may be transferred

with such indebtedness. This Guaranty is binding not only on Guarantor, but on
Guarantor's successors and assigns.

         16. Guarantor recognizes that Administrative Agent and Lenders are
relying upon this Guaranty and the undertakings of Guarantor hereunder in making
extensions of credit to Borrower under the Credit Agreement and further
recognizes that the execution and delivery of this Guaranty is a material
inducement to Administrative Agent and Lenders in entering into the Credit
Agreement. Guarantor hereby acknowledges that there are no conditions to the
full effectiveness of this Guaranty.

         17. This Guaranty is a Credit Document and, therefore, this Guaranty is
subject to the applicable provisions of the Credit Agreement, all of which
applicable provisions are incorporated herein by reference. Moreover, Guarantor
acknowledges and agrees that this Guaranty is subject to the offset provisions
in favor of Lenders in the Credit Agreement.

         18. Guarantor expressly assumes all responsibilities to remain informed
of the financial condition of Borrower and any circumstances affecting (a)
Borrower's ability to perform under the Credit Agreement and the other Credit
Documents to which it is a party or (b) any collateral securing all or any part
of the Guaranteed Indebtedness.

         19. In the event that Guarantor is entitled to receive any notice under
the Uniform Commercial Code, as it exists in the state governing any such
notice, of the sale or other disposition of any collateral securing all or any
part of the Guaranteed Indebtedness or this Guaranty, reasonable notice shall be
deemed given when such notice is deposited in the United States mail, postage
prepaid, at the address for Guarantor set forth on the signature page of this
Guaranty, five days prior to the date any public sale, or after which any
private sale, of any such collateral is to be held; provided, however, that
notice given in any other reasonable manner or at any other reasonable time
shall be sufficient.

         20. No delay on the part of Administrative Agent or any Lender in
exercising any right hereunder or failure to exercise the same shall operate as
a waiver of such right. In no event shall any waiver of the provisions of this
Guaranty be effective unless the same be in writing and signed by the
appropriate parties in accordance with the Credit Agreement, and then only in
the specific instance and for the purpose given.

and subject to the terms and conditions of this agreement. If the grant, pledge

remains effective to the extent allowed by UCC ss.9.318 or other applicable
Governmental Requirements, but is otherwise limited by that prohibition.

security only in order to secure the prompt, unconditional and complete payment
and performance of the Obligation when due. Neither Secured Party nor any Lender
assumes or may become liable for any Debtors' liabilities, duties or obligations
under or in connection with the Collateral. Neither Secured Party's acceptance
of this agreement nor its taking any action in carrying out this agreement,
constitutes Secured Party's approval of the Collateral or Secured Party's
assumption of any obligation under or in connection with the Collateral. This
agreement does not affect or modify any Debtors' obligations with respect to any
Collateral.

                                             Debtor, all of its:

                           (i)      Accounts;

                           (ii)     Chattel Paper;

                           (iii)    Instruments (including, without limitation,
                                    the Master Notes);

                           (iv)     General Intangibles, Partnership Interests
                                    and Securities;

                           (v)      Investment Property;

                           (vi)     Documents;

                           (vii)    Equipment (including, without limitation,
                                    all Motor Vehicles);

                           (viii)   Inventory;

                           (ix)     Intellectual Property;

                           (x)      all other goods and personal property of any
                                    Debtor whether tangible or intangible;

                           (xi)     all Proceeds and products of any or all of
                                    the foregoing.

         5. Fraudulent Conveyance. Notwithstanding any contrary provision, each
Debtor agrees that, if - but for the application of this paragraph - any of the
Obligation or the Security Interest would constitute a preferential transfer
under 11 U.S.C. ss.547, a fraudulent conveyance under 11 U.S.C. ss.548, or a
fraudulent conveyance or transfer under any state fraudulent conveyance,
fraudulent transfer or similar Governmental Requirement in effect from time to
time (each a "FRAUDULENT CONVEYANCE"), then the Obligation and Security Interest
remains enforceable to the maximum extent possible without causing any of the
Obligation or the Security Interest to be a fraudulent conveyance, and this
agreement is automatically amended to carry out the intent of this paragraph.

         6. Representations and Warranties. Debtors jointly and severally
represent and warrant to Secured Party on behalf of Lenders that:

                  (a) Credit Agreement. All representations and warranties in
         the Credit Agreement that are applicable to each Debtor or its assets
         or operations are accurate and complete and are ratified and confirmed.

                  (b) Binding Obligation. This agreement creates a legal, valid
         and binding Lender Lien in and to the Collateral (subject to delivery
         to Secured Party of the stock certificates for the Securities) in favor
         of Secured Party and enforceable against the Debtor owning the
         Collateral. For Collateral in which the Security Interest may have been
         perfected by the filing of Financing Statements, once those Financing
         Statements have been properly filed in the jurisdictions contemplated
         by the Credit Documents, the Security Interest in that Collateral will
         be fully perfected. For the Securities, the taking by Secured Party of
         physical possession in Texas of the stock certificates representing the
         Securities will perfect the Security Interest in that Collateral. Once
         perfected, the Security Interest will constitute a first-priority
         Lender Lien on the Collateral, subject to no other Liens. The creation
         of the Security Interest does not require the consent of any Person
         that has not been obtained.

                  (c) Locations. SCHEDULE 7.3 to the Credit Agreement accurately
         describes (i) the location of each Debtor's principal place of business
         and chief executive office, (ii) if different from CLAUSE (i)




                                       5
<PAGE>   87




         above, the one or more locations of its books and records concerning
         its Accounts, (iii) the locations where any of its Inventory (except
         when temporarily in the hands of a third-party contractor for
         processing and until sold in the ordinary course of business) is
         currently and will - subject to PARAGRAPH 7(b) below - in the future be
         maintained, and (iv) none of the locations described on SCHEDULE 7.3 to
         the Credit Agreement have changed within six months before the date of
         this agreement. Except as stated in CLAUSE (iii) above, each Debtor's
         Inventory is currently and will be in its possession. No Equipment of
         any Debtor is kept at any location except the real properties for such
         Debtors identified on SCHEDULE 7.3 to the Credit Agreement.

                  (d) Accounts. Each Debtor's Accounts (i) arise from its sales
         or rendition of services, (ii) are due to that Debtor, and (iii) are
         not subject to any material setoff, counterclaim, defense, allowance,
         adjustment (other than discounts for prompt payment shown on the
         invoice), or material dispute, objection or complaint by any Obligor.

                  (e) Securities. All Securities are duly authorized, validly
         issued, fully paid and non-assessable, and the transfer of them is not
         subject to any restrictions other than restrictions imposed by
         applicable Governmental Requirements. The Securities described on
         SCHEDULES 5-A and 5-B are approximately the maximum number of shares of
         each Subsidiary that may be pledged without creating a material Tax
         obligation for the Companies that would not otherwise exist. With
         respect to all Collateral that is Securities which are subject to Rule
         144 under the Securities Act of 1933, as such rule and act are amended
         at the time in question and any successor in whole or in part thereto,
         (a) the applicable Debtor is the beneficial and record owner thereof,
         free and clear of any Liens or transfer restrictions (other than
         restrictions on the amount thereof which may be sold, and the manner in
         which sales may be made, imposed by such Rule 144), (b) the applicable
         Debtor acquired such Securities directly from the issuer thereof more
         than two (2) years prior to the date hereof in transactions not
         involving any public offering, (c) the applicable Debtor paid the
         purchase price therefor in cash more than two (2) years prior to the
         date hereof, (d) since such date of acquisition, the applicable Debtor
         has not had a short position in, or any put or option to dispose of,
         any capital stock of any issuer thereof or Securities convertible into
         capital stock of any issuer thereof, (e) neither the applicable Debtor,
         nor any person or entity, the sales of which are required by Rule 144
         to be aggregated with the sales of such Debtor, has sold any capital
         stock of any issuer of such Securities during the period of six (6)
         months prior to the date hereof, other than sales pursuant to an
         effective registration statement under the Securities Act of 1933, as
         amended, and (f) to such Debtor's best knowledge, each issuer of such
         Securities has timely filed all reports required to be filed by it
         under the Securities Exchange Act of 1934, as amended.

                                    (f) Perfection. Upon the filing of Uniform
                           Commercial Code financing statements in the
                           jurisdictions listed on SCHEDULE 6 attached hereto,
                           the filing of this Security Agreement or any
                           assignment documents contemplated at closing with the
                           United States Patent and Trademark Office, and upon
                           the Secured Party's obtaining possession or control
                           of all Securities of the Debtors, the security
                           interest in favor of the Secured Party created herein
                           will constitute a valid and perfected lien upon and
                           security interest in the Collateral, subject to no
                           equal or prior liens (it is recognized that such
                           property may be covered by certain liens in respect
                           of the Refinanced Debt that are being released
                           concurrently with the closing of the Credit
                           Agreement).

                           (g) Intellectual Property.

                                    (i) All of the Intellectual Property is
                           subsisting, valid and enforceable. The information
                           contained on SCHEDULE 1 hereto is true, correct and
                           complete. No Debtor owns any material item of
                           Intellectual Property except as set forth on SCHEDULE
                           1 hereto.

                                    (ii) The specified Debtors are the sole and
                           exclusive owners of the entire and unencumbered
                           right, title and interest in and to the Intellectual
                           Property free and clear of any liens, charges or
                           encumbrances, including, without limitation, any
                           pledges, assignments, licenses, user agreements and
                           covenants by any Debtor not to sue third Persons (it
                           is recognized that such property may be covered by
                           certain liens in respect of the Refinanced Debt that
                           are being released concurrently with the closing of
                           the Credit Agreement).

                                    (iii) No claim has been made that the use of
                           any material amount of the Intellectual Property
                           violates or may violate the rights of any third
                           Person.

                                    (iv) The subject matter of the Intellectual
                           Property identified on SCHEDULE 1 hereto has been
                           properly registered or filed with the United States
                           Patent and Trademark Office.

                  (h) Additional Collateral. The foregoing representations and
         warranties will be true and correct in all respects with respect to any
         additional Collateral or additional specific descriptions of certain
         collateral delivered to Secured Party in the future by any Debtor.

The failure of any of these representations or warranties to be accurate and
complete does not impair the Security Interest in any Collateral.

         7. Covenants. While any Lender is committed to lend or extend credit
under the Credit Agreement and until the Obligation is fully paid and performed,
each Debtor jointly and severally covenants and agrees with Secured Party on
behalf of Lenders that, without first obtaining Secured Party's written notice
of Required Lenders' consent to the contrary:

                  (a) Credit Agreement. Each Debtor shall promptly and fully
         comply with and perform all covenants and agreements in the Credit
         Agreement that are applicable to it or its assets or operations, each
         of which is ratified and confirmed.

                  (b) Certain Relocations and Changes. Each Debtor shall give
         Secured Party 30 days' written notice before any proposed (i)
         relocation of its principal place of business or chief executive
         office, (ii) relocation of the place where its books and records
         concerning its Accounts are kept, (iii) change of its name, and (iv)
         relocation of any Collateral (other than delivery of Inventory in the
         ordinary course of business to third-party contractors for processing
         and sales of Inventory in the ordinary course of business) to a
         location not described on SCHEDULE 7.3 to the Credit Agreement as being
         a location for that Debtor or any other relocation that would cause the
         Lender Liens to be impaired in any way.

                  (c) Estoppel and Other Agreements. Each Debtor shall:



                                       7
<PAGE>   89

                           (i) Within 90 days after the date of this agreement
                  and at all times after that time, with respect to any of its
                  Inventory that is from time to time delivered to any
                  third-party contractor for processing in the ordinary course
                  of business, deliver to Secured Party a bailee, estoppel and
                  subordination agreement providing that such third-party
                  contractor holds that Inventory as Secured Party's bailee,
                  subordinates to the Security Interest all right, title and
                  interest it may have in and to that Inventory, and covenants
                  to keep that Inventory segregated and clearly marked as being
                  owned by that Debtor, which agreement must otherwise be in
                  form and substance reasonably acceptable to Secured Party and
                  its special counsel; and

                           (ii) Either (A) cause the landlord or lessor for each
                  location where any of its Inventory is maintained to execute
                  and deliver to Secured Party an estoppel and subordination
                  agreement in substantially the form of the attached SCHEDULE 7
                  or such other form as may be reasonably acceptable to Secured
                  Party and its special counsel, or (B) deliver to Secured Party
                  a legal opinion or other evidence (in each case that is
                  reasonably satisfactory to Secured Party and its special
                  counsel) that neither the applicable lease nor the
                  Governmental Requirements of the jurisdiction in which that
                  location is situated provide for contractual, common law, or
                  statutory landlord's Liens. The requirements of this clause
                  (c)(ii) are modified as follows: (x) an executed landlord
                  estoppel and subordination agreement with respect to the 1301
                  Waters Ridge Dr., Lewisville, Texas location will be delivered
                  by Borrower/Debtor to Secured Party promptly after the Closing
                  Date and (y) executed landlord estoppel and subordination
                  agreements or legal opinions as described above with respect
                  to all other locations leased by any Debtor will be delivered
                  as soon as practicable on a best efforts basis on the part of
                  Borrower/Debtor, provided that at all times at least 85% of
                  the Debtors' aggregate inventory will be maintained at
                  locations either owned by a Debtor or leased by a Debtor and
                  covered by a landlord estoppel and subordination agreement or
                  legal opinion as described above.

                                    (d) Foreign Account Debtors. With respect to
                           any Account on which the account debtor is Foreign,
                           Borrower shall promptly cause such Account to be (i)
                           supported by one or more letters of credit that are
                           in form and substance (and are issued by one or more
                           Persons) acceptable to Secured Party in its sole
                           discretion; or (ii) supported by Approved Foreign
                           Credit Insurance in amounts and on terms acceptable
                           to Secured Party in its sole discretion.
                           Notwithstanding the preceding sentence, up to
                           $2,000,000 in the aggregate of Accounts owed by
                           Foreign account debtors may be excluded from the
                           requirements set forth in CLAUSES (i) and (ii) of the
                           preceding sentence if Borrower/Debtor so elects. In
                           addition, additional Accounts owed by Foreign account
                           debtors may be excluded from the requirements set
                           forth in CLAUSES (i) and (ii) of the first sentence
                           of this CLAUSE (d) if request therefor is made by
                           Borrower/Debtor and agreed to by Secured Party in its
                           sole discretion.

                                    (e) Governmental Accounts. With respect to
                           any Accounts owed by the U.S. federal government, any
                           state or local government, or any agency, department
                           or instrumentality thereof, as to which a valid,
                           perfected, first-priority lien on it, or the ability
                           to obtain direct payment of the proceeds of it, is
                           governed by any Governmental Requirement other than
                           the applicable UCC, Borrower shall promptly cause all
                           actions and documents deemed appropriate by Secured
                           Party under applicable Governmental Requirements to
                           be taken and delivered to assign and perfect a first-
                           priority lien on such Accounts in favor of Secured
                           Party for Lenders, or to cause Secured Party to
                           obtain direct payment of the proceeds of such
                           Accounts. Notwithstanding the preceding




                                       8
<PAGE>   90




                           sentence, up to $2,000,000 in the aggregate of
                           Accounts owed by governmental authorities as
                           described above may be excluded from the requirements
                           set forth in the preceding sentence of this CLAUSE
                           (e) if Borrower/Debtor so elects. In addition,
                           additional Accounts owed by governmental authorities
                           as described above may be excluded from the
                           requirements set forth in the first sentence of this
                           CLAUSE (e) if request therefor is made by
                           Borrower/Debtor and agreed to by Secured Party in its
                           sole discretion.

                  (f) Other Notices and Actions. Each Debtor shall promptly
         notify Secured Party of (i) any change in any material fact or
         circumstance represented or warranted by any Debtor with respect to any
         of the Collateral, (ii) any claim, action or proceeding challenging the
         Security Interest or affecting title to all or any portion of the
         Collateral or the Security Interest (and, at Secured Party's request,
         that Debtor shall appear in and defend any such action or proceeding at
         that Debtor's expense), (iii) any default or event of default by that
         Debtor or any other party under or in connection with any portion
         (individually or collectively) of the Collateral (and it shall
         immediately use reasonable efforts to remedy the same or immediately
         demand that the same be remedied).

                  (g) Record of Collateral. Each Debtor shall maintain at its
         chief executive office a current record of where all of its Collateral
         is located and permit Secured Party or its representatives to inspect
         and make copies from those records pursuant to the Credit Agreement and
         furnish to Secured Party, from time to time, such documents, lists,
         descriptions, certificates and other information necessary or helpful
         to keep Secured Party informed with respect to the identity, location,
         status, condition, terms of, parties to, and value of the Collateral.

                  (h) Collateral in Trust. Each Debtor shall (i) hold in trust
         (and not commingle with its other assets) for Secured Party all of its
         Collateral that is contracts, chattel paper, instruments or documents
         of title at any time received by it, (ii) promptly deliver that
         Collateral to Secured Party unless Secured Party at its option gives
         Debtor written permission to retain any of it, and (iii) cause each
         contract, chattel paper, instrument or document of title so retained to
         be marked to state that it is assigned to Secured Party and each
         instrument to be endorsed to the order of Secured Party (but failure to
         be so marked or endorsed may not impair the Security Interest in any
         such Collateral).

                  (i) Perform Obligations. Each Debtor shall perform all of its
         material obligations under or in connection with all of its Collateral
         in accordance with customary business practices.

                  (j) Amendments, Etc. No Debtor may amend, alter or modify, or
         permit the amendment, alteration or modification of, any material
         portion (individually or collectively) of any Collateral (other than
         the processing of Inventory in the ordinary course of business).

                  (k) Impairment of Collateral. No Debtor may do or permit any
         act that is reasonably likely to adversely impair the value or
         usefulness of any material portion of any Collateral.

                  (l) Further Assurances. Debtors shall deliver such documents,
         instrument, certificates or other documents as are necessary from time
         to time to maintain and protect the Lender Liens in the Collateral and
         to update the schedules attached to this agreement so as to cause such
         schedules to remain true, correct and complete.

         8. Remedies Under Default. While an Event of Default exists, Secured
Party is, subject to the Credit Agreement, entitled to exercise any one or more
of the following Rights:

                  (a) Rights. Secured Party may exercise any and all Rights
         available to a secured party under the UCC, in addition to any and all
         other Rights afforded by this agreement and the other Credit Documents,
         at law, in equity, or otherwise, including, without limitation (i)
         requiring Debtors to



                                       9
<PAGE>   91


         assemble Collateral and make it available to Secured Party at a place
         to be designated by Secured Party which is reasonably convenient to the
         applicable Debtor and Secured Party, (ii) applying by appropriate
         judicial proceedings for appointment of a receiver for Collateral,
         (iii) applying to the Obligation any cash held by Secured Party under
         this agreement, (iv) reducing any claim to judgment, (v) exercising the
         Rights of offset or banker's Lien against the interest of each Debtor
         in and to every account and other property of each Debtor in Secured
         Party's possession to the extent of the full amount of the Obligation,
         (vi) foreclosing the Security Interest and any other Liens Secured
         Party may have or otherwise realize upon any and all of the Rights
         Secured Party may have in and to Collateral, and (vii) bringing suit or
         other proceedings before any Governmental Authority either for specific
         performance of any covenant or condition contained in any of the Credit
         Documents, or in aid of the exercise of any Right granted to Secured
         Party in any Credit Document.

                  (b) Notice. If any Collateral threatens to decline speedily in
         value or is of the type customarily sold on a recognized market,
         Secured Party may sell or otherwise dispose of that Collateral without
         notification, advertisement, or other notice of any kind. Otherwise,
         reasonable notice of the time and place of any public sale of the
         Collateral, or reasonable notification of the time after which any
         private sale or other intended disposition of the Collateral is to be
         made, shall be sent to Debtors and to any other Person entitled to
         notice under the UCC. Notice sent or given not less than ten calendar
         days prior to the taking of the action to which the notice relates is
         reasonable notice. It is not necessary that the Collateral be at the
         location of the sale.

                  (c) Sales of Securities. In connection with the sale of any
         Collateral that is securities, Secured Party is authorized, but not
         obligated, to limit prospective purchasers, to the extent deemed
         necessary or desirable by Secured Party to render that sale exempt from
         the registration and similar requirements under applicable Governmental
         Requirements, and no sale so made in good faith by Secured Party may be
         deemed not to be "commercially reasonable" because so made.

                  (d) Other Sales. Secured Party's sale of less than all
         Collateral does not exhaust Secured Party's Rights under this agreement
         and Secured Party is specifically empowered to make successive sales
         until all Collateral is sold. If the proceeds of a sale of less than
         all Collateral is less than the Obligation, then this agreement and the
         Security Interest remain in full force and effect as to the unsold
         portion of the Collateral just as though no sale had been made. In the
         event any sale under this agreement is not completed or is, in Secured
         Party's opinion, defective, that sale does not exhaust Secured Party's
         Rights under this agreement, and Secured Party is entitled to cause a
         subsequent sale or sales to be made. All statements of fact or other
         recitals made in any bill of sale or assignment or other instrument
         evidencing any foreclosure sale under this agreement - whether about
         nonpayment of the Obligation, the occurrence of any Event of Default,
         Secured Party's having declared all of the Obligation to be due and
         payable, notice of time, place and terms of sale and the properties to
         be sold having been duly given, or any other act or thing having been
         duly done by Secured Party - shall be taken as prima facie evidence of
         the truth of the facts so stated and recited. Secured Party may appoint
         or delegate any one or more Persons as agent to perform any act or acts
         necessary or incident to any sale held by Secured Party, including the
         sending of notices and the conduct of sale, but such acts must be done
         in the name and on behalf of Secured Party.

                  (e) Obligors. While an Event of Default (other than as
         described in Section 11.3 of the Credit Agreement) exists, Secured
         Party may, after three days' notice to Borrower/Debtor, notify or
         require each Obligor to make payment directly to Secured Party, and
         Secured Party may take control of the proceeds paid to Secured Party.
         While an Event of Default described in Section 11.3 of the Credit
         Agreement exists, Secured Party may at any time, without any required
         notice to Borrower/Debtor, notify or require each Obligor to make
         payment directly to Secured Party, and Secured Party may take control
         of the proceeds paid to Secured Party. Until Secured Party elects to
         exercise these Rights, each Debtor is authorized to collect and enforce
         the Collateral and to retain and expend all payments made on
         Collateral. While Secured Party is entitled to and elects to exercise
         these Rights, Secured Party has the Right in its own name or in the
         name of the applicable Debtor to



                                       10
<PAGE>   92


         (i) compromise or extend time of payment with respect to Collateral for
         such amounts and upon such terms as Secured Party may reasonably
         determine, (ii) demand, collect, receive, receipt for, sue for,
         compound, and give acquittance for any and all amounts due or to become
         due with respect to Collateral, (iii) take control of cash and other
         proceeds of any Collateral, (iv) endorse the applicable Debtor's name
         on any notes, acceptances, checks, drafts, money orders, or other
         evidences of payment on Collateral that may come into Secured Party's
         possession, (v) sign the applicable Debtor's name on any invoice or
         bill of lading relating to any Collateral, on any drafts against
         Obligors or other Persons making payment with respect to Collateral, on
         assignments and verifications of accounts or other collateral, and on
         notices to Obligors making payment with respect to Collateral, (vi)
         send requests for verification of obligations to any Obligor, and (vii)
         do all other acts and things reasonably necessary to carry out the
         intent of this agreement. If any Obligor fails to make payment on any
         Collateral when due, Secured Party is authorized, in its sole
         discretion, either in its own name or in the applicable Debtor's name,
         to take such action as Secured Party reasonably shall deem appropriate
         for the collection of any amounts owed with respect to Collateral or
         upon which a delinquency exists. However, Secured Party is neither (x)
         liable for its failure to collect, or for its failure to exercise
         diligence in the collection of, any amounts owed with respect to
         Collateral (except for its own fraud, gross negligence, willful
         misconduct, or violation of any applicable Government Requirement), nor
         (y) under any duty whatever to anyone except the applicable Debtor and
         Lenders to account for funds that it shall actually receive under this
         agreement. A receipt given by Secured Party to any Obligor is a full
         and complete release, discharge and acquittance to that Obligor, to the
         extent of any amount so paid to Secured Party. Secured Party may apply
         or set off amounts paid and the deposits against any liability of the
         applicable Debtor to Secured Party. Regarding the existence of any
         Event of Default for purposes of this agreement, each Debtor agrees
         that the Obligors on any Collateral may rely upon written certification
         from Secured Party that an Event of Default exists.

                  (f) Power-of-Attorney. Secured Party is deemed to be
         irrevocably appointed as each Debtor's agent and attorney-in-fact with
         all Right to enforce all of that Debtor's Rights under or in connection
         with the Collateral effective and operable at all times while an Event
         of Default exists. All reasonable costs, expenses and liabilities
         incurred and all payments made by Secured Party, as that Debtor's agent
         and attorney-in-fact (including, without limitation, reasonable
         attorneys' fees and expenses) are considered a loan by Secured Party to
         that Debtor that is repayable on demand, accrues interest at the
         Default Rate until paid, and is part of the Obligation.

                  (g) Application of Proceeds. While an Event of Default exists,
         Secured party shall apply the proceeds of any sale or other disposition
         of Collateral in the following order: (i) payment of all its reasonable
         expenses incurred in retaking, holding and preparing any Collateral for
         disposition, in arranging for such disposition, and in actually
         disposing of the same (all of which are part of the Obligation); (ii)
         repayment of amounts reasonably expended by Secured Party under
         PARAGRAPH 9 below; (iii) payment of the balance of the Obligation in
         the order and manner specified in the Credit Agreement; and (iv)
         delivery either (A) to Borrower/Debtor for the account of all Debtors,
         or (B) as a court of competent jurisdiction may direct.

         9. Other Rights.

                  (a) Performance. If any Debtor fails to preserve the priority
         of the Security Interest in any Collateral or otherwise fails to
         perform any of its obligations under any Credit Document with respect
         to any Collateral, then Secured Party may, at its option, but without
         being required to do so, prosecute or defend any suits in relation to
         the Collateral or take any other action that such Debtor is required,
         but has failed, to take. Any amount that is reasonably expended or paid
         by Secured Party in connection with the foregoing (including, without
         limitation, court costs and reasonable attorneys' fees and expenses)
         bears interest at the Default Rate from the date spent or incurred
         until repaid and is payable (with that interest) by Debtors to Secured
         Party upon demand and is part of the Obligation.



                                       11
<PAGE>   93

                  (b) Collateral in Secured Party's Possession. If, while an
         Event of Default exists, any Collateral comes into Secured Party's
         possession, Secured Party may use that Collateral for the purpose of
         preserving it or its value pursuant to the order of a court of
         appropriate jurisdiction or in accordance with any other Rights held by
         Secured Party in respect of that Collateral. Debtors jointly and
         severally covenant to promptly reimburse and pay to Secured Party, at
         Secured Party's request, the amount of all reasonable expenses, costs,
         Taxes and other charges incurred by Secured Party in connection with
         its custody and preservation of that Collateral, all of which bear
         interest at the Default Rate from the date spent or incurred until
         repaid and are (with that interest) payable by Debtors to Secured Party
         upon demand and are part of the Obligation. Except for Secured Party's
         own fraud, gross negligence, or willful misconduct (i) the risk of
         accidental loss or damage to, or diminution in value of, any Collateral
         is on Debtors, (ii) Secured Party has no liability for failure to
         obtain or maintain insurance or to determine whether any insurance in
         effect is adequate as to amount or risks insured, (iii) Secured Party
         has no duty to fix or preserve Rights against any Obligors in respect
         of any Collateral and is never liable for any failure to use diligence
         to collect any amount payable in respect of any Collateral (other than
         to account to Debtors and Lenders for what Secured Party may actually
         collect or receive).

                  (c) Record Ownership of Securities. While an Event of Default
         exists, Secured Party may have any Collateral that is securities and
         that is in the possession of Secured Party, or its nominee or nominees,
         registered in its name, or in the name of its nominee or nominees, as
         pledgee.

                  (d) Voting of Securities. As long as no Event of Default
         exists, the applicable Debtor may exercise all voting Rights pertaining
         to any Collateral that is securities. While an Event of Default exists,
         the Right to vote any Collateral that is securities is vested
         exclusively in Secured Party. Accordingly, each applicable Debtor
         irrevocably constitutes and appoints Secured Party as that Debtor's
         proxy and attorney-in-fact - effective only while an Event of Default
         exists but with full power of substitution - to vote, and to act with
         respect to, any Collateral that is securities standing in the name of
         that Debtor or with respect to which that Debtor is entitled to vote
         and act. That proxy is coupled with an interest, is irrevocable, and
         continues until the Obligation is fully paid and performed.

                  (e) Certain Proceeds. The provisions of this CLAUSE (E) are
         applicable only while an Event of Default exists. Notwithstanding any
         contrary provision, all dividends or distributions of property in
         respect of, and all proceeds of, any Collateral that is securities -
         whether those dividends, distributions or proceeds result from a
         subdivision, combination or reclassification of the outstanding capital
         stock of any issuer or as a result of any merger, consolidation,
         acquisition, or other exchange of assets to which any issuer may be a
         party, or otherwise - are part of the Collateral, shall, if received by
         any Debtor, be held in trust for Secured Party's benefit, and shall
         immediately be delivered to Secured Party (accompanied by proper
         instruments of assignment or stock or bond powers executed by the
         applicable Debtor in accordance with Secured Party's instructions) to
         be held subject to the terms of this agreement. Any cash proceeds of
         any Collateral that come into Secured Party's possession (including,
         without limitation, insurance proceeds) may, at Secured Party's option,
         be applied in whole or in part to the Obligation (to the extent then
         due), be fully or partially released to or under the written
         instructions of that applicable Debtor for any general or specific
         purpose, or be fully or partially retained by Secured Party as
         additional Collateral. Any cash Collateral in Secured Party's
         possession may be invested by Secured Party in certificates of deposit
         issued by Secured Party, any Lender, or any other state or national
         bank having combined capital and surplus greater than $100,000,000 or
         in securities issued or guaranteed by the United States of America or
         any of its agencies. Secured Party is never obligated to make any
         investment and never has any liability to any Debtor or any Lender for
         any loss that may result from any investment or non-investment. All
         interest and other amounts earned from any investment may be dealt with
         by Secured Party in the same manner as other cash Collateral.

<PAGE>   94





                  (f) INDEMNIFICATION. DEBTORS JOINTLY AND SEVERALLY ASSUME ALL
         LIABILITY FOR ALL COLLATERAL, FOR THE SECURITY INTEREST, AND FOR ANY
         USE, POSSESSION, MAINTENANCE AND MANAGEMENT OF, ALL COLLATERAL
         (INCLUDING, WITHOUT LIMITATION, ANY TAXES ARISING AS A RESULT OF, OR IN
         CONNECTION WITH, THE TRANSACTIONS CONTEMPLATED IN THIS AGREEMENT) AND
         JOINTLY AND SEVERALLY AGREE TO ASSUME LIABILITY FOR, AND TO INDEMNIFY
         AND HOLD SECURED PARTY, EACH LENDER AND THEIR RESPECTIVE
         REPRESENTATIVES (THE "INDEMNIFIED PARTIES") HARMLESS FROM AND AGAINST,
         AND DEFEND EACH INDEMNIFIED PARTY AGAINST, ALL CLAIMS, CAUSES OF
         ACTION, OR LIABILITY, FOR INJURIES TO OR DEATHS OF PERSONS AND DAMAGE
         TO PROPERTY HOWSOEVER ARISING FROM OR INCIDENT TO SUCH USE, POSSESSION,
         MAINTENANCE AND MANAGEMENT (WHETHER SUCH PERSONS BE AGENTS OR EMPLOYEES
         OF ANY DEBTOR OR OF THEIR PARTIES, OR SUCH DAMAGE BE TO PROPERTY OF ANY
         DEBTOR OR OF OTHERS) AND ALL LOSSES, DAMAGES, CLAIMS, COSTS, PENALTIES,
         LIABILITIES AND EXPENSES, INCLUDING, WITHOUT LIMITATION, COURT COSTS
         AND ATTORNEYS' FEES, HOWEVER ARISING OR INCURRED BECAUSE OF, INCIDENT
         TO, OR WITH RESPECT TO COLLATERAL OR ANY USE, POSSESSION, MAINTENANCE
         OR MANAGEMENT OF IT (THE "INDEMNIFIED LIABILITIES"). HOWEVER, NO
         INDEMNIFIED PARTY IS ENTITLED TO INDEMNITY UNDER THIS PARAGRAPH FOR ITS
         OWN GROSS NEGLIGENCE, WILLFUL MISCONDUCT OR FRAUD, OR FOR ANY
         INDEMNIFIED LIABILITY ARISING FROM ITS ACTIONS AFTER SECURED PARTY HAS
         FORECLOSED THE SECURITY INTEREST OR ACCEPTED CONVEYANCE IN LIEU OF
         FORECLOSURE OR (EXCEPT FOR THE SECURITIES) TAKEN POSSESSION OF ANY
         COLLATERAL. The provisions of this paragraph survive the payment and
         performance of the Obligation and the release of the Security Interest.

                  (g) Subrogation. If any of the Obligation is given in renewal
         or extension or applied toward the payment of Debt secured by any Lien,
         Secured Party is subrogated to all of the Rights, titles, interests and
         Liens securing that Debt.

         10. Miscellaneous.

                  (a) Term. This agreement terminates when no Lender has any
         commitment to lend or extend credit under the Credit Agreement and the
         Obligation is fully paid and performed. No Obligor on any Collateral is
         obligated to inquire about the termination of this agreement and is
         fully protected in making payments directly to Secured Party, which
         payments Secured Party shall pay to Borrower/Debtor on behalf of
         Debtors after termination of this agreement.

                  (b) No Release. Neither the Security Interest, any Debtor's
         obligations, nor Secured Party's or any Lenders' Rights under this
         agreement are released, diminished, impaired, or adversely affected by
         the occurrence of any one or more of the following events (i) the
         taking or accepting of any other security or assurance for any
         Obligation; (ii) any release, surrender, exchange, subordination or
         loss of any security or assurance at any time existing in connection
         with the Obligation; (iii) the modification of, amendment to, or waiver
         of compliance with any terms of any other Credit Document without the
         consent of Debtors except as required in that Credit Document; (iv) any
         present or future insolvency, bankruptcy, or lack of corporate or trust
         power of any party at any time liable for the payment of any
         Obligation; (v) except as specifically required by any other Credit
         Document, any renewal, extension or rearrangement of the payment of any
         Obligation (either with or without notice to or consent of any Debtor)
         or any adjustment, indulgence, forbearance or compromise that may be
         granted or given by Secured Party or any Lender to any Debtor (vi) any
         neglect, delay, omission, failure or refusal of Secured Party or any
         Lender to take or prosecute any action in connection with any
         agreement, document, guaranty or instrument evidencing, securing or
         assuring the payment of any Obligation; (vii) any failure of Secured
         Party or any Lender to notify any Debtor of any renewal, extension or
         assignment of any Obligation, or the release of any security under any
         other document or instrument, or of any other action taken or refrained
         from being taken by Secured Party or any Lender against any Debtor, or
         any new agreement between Secured Party, any Lender, and any Debtor, it
         being understood that, except as expressly required by the Credit
         Agreement, neither Secured Party nor any Lender is required to give any
         Debtor any notice of any kind under any




                                       13
<PAGE>   95




         circumstances whatsoever with respect to or in connection with the
         Obligation, including, without limitation, notice of acceptance of this
         agreement or any Collateral ever delivered to or for the account of
         Secured Party under this agreement; (viii) the illegality, invalidity
         or unenforceability of any Obligation against any third party obligated
         with respect to it by reason of the fact that the Obligation, or the
         interest paid or payable with respect to any of it, exceeds the amount
         permitted by applicable Governmental Requirements, the act of creating
         any of it is ultra vires, or the officers, partners or trustees
         creating any of it acted in excess of their authority, or for any other
         reason; or (ix) if any payment by any party obligated with respect to
         any Obligation is held to constitute a preference under applicable
         Governmental Requirements or for any other reason Secured Party or any
         Lender is required to refund any payment on any Obligation or pay the
         amount of it to someone else.

                  (c) Waivers. To the maximum extent lawful, except to the
         extent expressly otherwise provided in this agreement or in any other
         Credit Document, Debtors jointly and severally waive (i) any Right to
         require Secured Party or any Lender to proceed against any other
         Person, to exhaust Rights in Collateral, or to pursue any other Right
         that Secured Party or any Lender may have; (ii) with respect to the
         Obligation, presentment and demand for payment, protest, notice of
         protest and nonpayment, notice of acceleration, and notice of intent to
         accelerate; and (iii) all Rights of marshaling with respect of any
         Collateral.

                  (d) Financing Statement. Secured Party may at any time file
         this agreement (or a carbon, photographic, or other reproduction of
         this agreement) as a financing statement, but the failure of Secured
         Party to do so does not impair the validity or enforcement of this
         agreement.

                  (e) VENUE AND SERVICE OF PROCESS. SUBJECT TO THE VENUE AND
         SERVICE OF PROCESS PROVISIONS IS THE CREDIT AGREEMENT, EACH DEBTOR (i)
         IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF ANY TEXAS STATE
         OR FEDERAL COURT, (ii) IRREVOCABLY WAIVES -- TO THE FULLEST EXTENT
         PERMITTED BY LAW -- ANY OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE
         TO THE LAYING OF VENUE OF ANY LITIGATION BROUGHT IN CONNECTION WITH ANY
         CREDIT DOCUMENT OR THE OBLIGATION BROUGHT IN DISTRICT COURTS OF DALLAS
         COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
         DISTRICT OF TEXAS, DALLAS DIVISION (iii) IRREVOCABLY WAIVES ANY CLAIMS
         THAT ANY LITIGATION BROUGHT IN ANY OF THOSE COURTS HAS BEEN BROUGHT IN
         AN INCONVENIENT FORUM, (iv) IRREVOCABLY CONSENTS TO THE SERVICE OF
         PROCESS OUT OF ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF
         COPIES OF THAT LEGAL PROCESS BY CERTIFIED MAIL, RETURN RECEIPT
         REQUESTED, POSTAGE PREPAID, BY HAND-DELIVERY, OR BY DELIVERY BY A
         NATIONALLY RECOGNIZED COURIER SERVICE, AND SERVICE IS DEEMED COMPLETE
         UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS AS PROVIDED IN THIS
         AGREEMENT, AND (v) IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST
         ANY PARTY TO ANY CREDIT DOCUMENT ARISING OUT OF OR IN CONNECTION WITH
         THE CREDIT DOCUMENTS OR THE OBLIGATION MAY BE BROUGHT IN ONE OF THOSE
         COURTS. The scope of each of these waivers is intended to be
         all-encompassing of any and all disputes that may be filed in any court
         and that relate to the subject matter of this transaction -- including,
         without limitation, contract claims, tort claims, breach of duty
         claims, and all other common law and statutory claims. These waivers
         are a material inducement to the agreement by Secured Party and each
         Lender to enter into the Credit Documents, and they have each relied --
         and may continue to rely -- on these waivers in its dealings with
         Debtors. Each Debtor represents and warrants that it has reviewed these
         waivers with its legal counsel, and that it knowingly and voluntarily
         agrees to each waiver following consultation with legal counsel. These
         waivers are irrevocable, may not be modified either orally or in
         writing, and apply to any renewals, extensions, amendments, and
         replacements of any Credit Document.

                  (g) Credit Document. This agreement is a Credit Document and
         is subject to applicable provisions of SECTIONS 1 and 14 of the Credit
         Agreement, all of which are incorporated in this agreement by reference
         the same as if set forth in this agreement verbatim.

                  (h) Communications. For purposes of SECTION 14.2 of the Credit
         Agreement, each Debtor's address and telecopy number are the same as
         Borrower/Debtor's.

                  (i) Amendments, Etc.. No amendment, waiver, or discharge to or
         under this agreement is valid unless it is in writing and signed by the
         party against whom it is sought to be enforced as is otherwise in
         conformity with the requirements of SECTION 14.10 of the Credit
         Agreement.

                  (j) ENTIRETY. THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS TO
         WHICH ANY DEBTOR IS A PARTY REPRESENT THE FINAL AGREEMENT BETWEEN THE
         PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
         CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE
         ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                  (k) Secured Party and Lenders. Secured Party is the agent for
         each Lender under the Credit Agreement. The Security Interest and all
         Rights granted to Secured Party under or in connection with this
         agreement are for each Lender's ratable benefit. Secured Party may,
         without the joinder of any Lender, exercise any Rights in Secured
         Party's or Lenders' favor under or in connection with this agreement,
         including, without limitation, conducting any foreclosure sales and
         executing full or partial releases of, amendments or modifications to,
         or consents or waivers under this agreement. Secured Party's and each
         Lender's Rights and obligations vis-a-vis each other may be subject to
         one or more separate agreements between those parties. However, no
         Debtor need inquire about any such agreement or is subject to any terms
         of it unless that Debtor specifically joins it. Therefore, neither any
         Debtor nor its successors or assigns is entitled to any benefits or
         provisions of any such separate agreement or is entitled to rely upon
         or raise as a defense any party's failure or refusal to comply with the
         provisions of it.

                  (l) Parties. This agreement benefits Secured Party, Lenders,
         and their respective successors and assigns and binds each Debtor and
         its successors and assigns. Upon appointment of any successor
         Administrative Agent under the Credit Agreement, all of the Rights of
         Secured Party under this agreement automatically vests in that new
         Administrative Agent as successor Secured Party on behalf of Lenders
         without any further act, deed, conveyance, or other formality other
         than that appointment. The Rights of Secured Party and Lenders under
         this agreement may be transferred with any assignment of the
         Obligations. The Credit Agreement contains provisions governing
         assignments of the Obligations and of Rights and obligations under this
         agreement.

             PREMISES:  __________________________________, described on the
                        attached EXHIBIT A

         The undersigned is the landlord ("LANDLORD") under a lease (as renewed,
extended, amended, or substituted, the "LEASE") covering the Premises. Landlord
understands that Lessee is or will be party to, or a guarantor under, a Credit
Agreement (as renewed, extended, amended, or restated the "CREDIT AGREEMENT")
with you and certain lenders which requires (a) granting to you on behalf of
those lenders security interests in, among other things, all of Lessee's present
and future inventory and equipment now or in the future located at the Premises
(together with all cash and non-cash proceeds, the "COLLATERAL") and (b)
subordinating in your favor on behalf of those lenders any liens, security
interests, and other rights to which Landlord might be entitled in the
Collateral.

         To satisfy those requirements and induce you and those lenders to
extend credit under the Credit Agreement, Landlord agrees that, notwithstanding
anything to the contrary in the Lease, until all of Lessee's obligations to you
and those lenders have been paid and performed in full (a) all liens, security
interests, and other rights to which Landlord might be entitled in the
Collateral are subordinate and inferior to any present or future security
interests granted to you on behalf of those lenders in the Collateral,
regardless of the order in which any liens, security interests, and rights in
the Collateral were or will be created, attached, pledged, filed, recorded,
registered, or perfected, (b) Landlord intends that the Collateral will not
become fixtures and will be and remain personal property, notwithstanding the
manner of their annexation to the Premises, their adaptability to the uses and
purposes for which the Premises are used, and the intentions of the party making
the annexation, (c) Landlord will notify you in writing by Certified Mail,
Return Receipt Requested, at the above address, if Lessee defaults on its lease
obligations and grant to you the right but not the obligation to cure those one
or more defaults, (d) you and your representatives are entitled to enter upon
the Premises and assemble, appraise, display, sever, remove, maintain, prepare
for sale or lease, repair, lease, transfer, or sell at one or more public
auctions or private sales any Collateral, and (e) you may, without notice to
Landlord or Landlord's consent and without affecting the validity of this
agreement, increase, extend the times of payment of, or otherwise modify any of
Lessee's debts to you or the performance of any of the terms and conditions of
the Credit Agreement or related documents. This agreement inures to you, those
lenders, and the respective successors and assigns

of each and binds Landlord and Landlord's heirs, personal representatives,
successors, and assigns. Landlord waives notice of acceptance of this agreement.

                                      Very truly yours,

         3. Each Company is duly qualified to transact business and is in good
standing as a foreign corporation or other entity in each jurisdiction so
indicated on SCHEDULE 7.3 to the Credit Agreement and in each other jurisdiction
where, to the best of that counsel's knowledge, the nature and extent of that
Company's business and properties require due qualification and good standing.

         4. Each Company possesses all requisite corporate power and authority
to conduct its business as is now being -- or is contemplated by the Credit
Agreement to be -- conducted.

         5. The execution and delivery by each Company of each Credit Document
to which it is a party and the performance by it of its related obligations (a)

enforceability may be limited by applicable Debtor Relief Laws and general
principles of equity.

         7. Lender Liens are created and perfected on each item of Collateral
described in the Credit Documents.

         8. Except as disclosed on SCHEDULE 7.8 to the Credit Agreement (a) no
Company is subject to, or aware of the threat of, any Litigation that is

determined, would be a Material Adverse Event, and (b) no outstanding or unpaid
judgments against any Company exist.

         9. No Company is subject to regulation under the Investment Company Act
of 1940, as amended, or the Public Utility Holding Company Act of 1935, as
amended.

facility at the end of the ninety (90) day period and for any other inventory
that ADT earlier ships, or causes to be shipped, from Ultrak's facilities to ADT
or DVD and shall be liable for any loss or damage during loading or shipment.

binding agreement of each other party thereto, each such document constitutes a
valid and binding agreement of Ultrak, enforceable against Ultrak in accordance

                          ARTICLE VI: INDEMNIFICATION

     6.01. Mutual Indemnity. Subject to the terms and conditions of this 
Article VI, (a) ADT hereby agrees to indemnify, defend and hold Ultrak and 
Ultrak's officers, directors, and affiliates harmless from and against all 
losses, claims, obligations, demands, assessments, penalties, liabilities, 
costs, damages, attorneys' fees and expenses (collectively, "Damages"), 
asserted against or incurred by them by reason of or resulting from (i) any 
breach by ADT of any representation, warranty, or covenant contained herein or 
in any agreement executed pursuant hereto (including but not limited to the 
obligations under Section 4.01 hereof) or (ii) the failure of DVD to pay or 
perform any of its liabilities or obligations under Section 4.02 hereof or 
arising on or after the Effective Date and (b) Ultrak hereby agrees to 
indemnify, defend and hold ADT and ADT's officers, directors, and affiliates 
harmless from and against all Damages asserted against or incurred by them by 
reason of or resulting from (i) any breach by Ultrak of any representation, 
warranty, or covenant contained herein or in any agreement executed pursuant 
hereto or (ii) any liability or obligation of DVD or VVI for any act or 
activity of DVD or VVI that occurred prior to the Effective Date to the end 
that ADT shall be in the same position vis a vis DVD and VVI as if it had 
purchased the assets of DVD and VVI; provided, however, that, notwithstanding 
anything to the contrary in this Agreement, Ultrak shall have no liability or 
responsibility under this Section 6.01 or under any other provision of this 
Agreement for any matter covered by Sections 4.01 or 4.02 hereof.

     6.02. Conditions of Indemnification. The indemnity obligations under 
Section 6.01 hereof shall be subject to the following terms and conditions:

           (a) Within 20 days (or such earlier time as might be required to
avoid prejudicing the indemnifying party's position) after receipt of notice of
commencement of any action evidenced by service of process, or other legal
pleading, or with reasonable promptness after the assertion in writing of any
claim by a third party of a matter for which a party (the"indemnified party") is
entitled to indemnification under Section 6.01, the indemnified party shall give
the other party (the "indemnifying party") written notice thereof together with
a copy of such claim, process, or other legal pleading, and the indemnifying
party shall have the right to undertake the defense thereof by representatives
of its own choosing and at its own expense; provided, however, that the
indemnified party may participate in the defense with counsel of its own choice
and at its own expense. Notwithstanding the foregoing, if, in the reasonable
opinion of counsel to the indemnified party (which opinion must be furnished in
writing to the indemnified party), a potential conflict of interest shall exist
as between the indemnifying party and the indemnified party such that it would
not be in the best interest of the indemnified party to be represented by the
same counsel as the indemnifying party, the indemnified party shall be entitled
to retain separate counsel, all at the expense of the indemnified party;
provided, however, that in no


                                      -7-

<PAGE>   8
        event shall the indemnifying party be required to pay for more than one
        counsel for the indemnified party in any lawsuit, action, proceeding, or
        claim (including any related lawsuits, actions, proceedings, or claims).

            (b)   If the indemnifying party, by the 20th day after receipt of
        notice of any such claim (or, if earlier, by the 10th day preceding the
        day on which an answer or other pleading must be served in order to
        prevent judgment by default in favor of the person asserting such
        claim), does not notify in writing the indemnified party that the
        indemnifying party shall defend against such claim, then the
        indemnified party may (upon further notice to the indemnifying party)
        undertake the defense, compromise, or settlement of such claim on
        behalf of and for the account and risk of the indemnifying party and at
        the indemnifying party's expense, subject to the right of the
        indemnifying party to assume the defense of such claim at any time
        prior to settlement, compromise, or final determination thereof.

            (c)   Anything in this Section 6.02 to the contrary notwithstanding,
        the indemnifying party shall not settle any claim without the consent of
        the indemnified party unless such settlement involves only the payment
        of money and the claimant provides to the indemnified party a full and
        complete release from all liability in respect of such claim. If the
        settlement of the claim involves more than the payment of money, then
        the indemnifying party shall not settle the claim without the prior
        written consent of the indemnified party, which consent shall not be
        unreasonably withheld.

            (d)   Each of Ultrak and ADT will cooperate with all reasonable
        requests of the other pursuant to Section 6.01 and this Section 6.02.

        6.03.     Remedies Not Exclusive. The remedies provided in this 
Article VI shall not be exclusive of any other rights or remedies available by 
one party against the other, either at law or in equity; provided, however, 
that the parties agree to arbitrate disputes pursuant to Section 7.09.

                           ARTICLE VII: MISCELLANEOUS

        7.01.     Modification, Amendment and Waiver. This Agreement may not be 
modified unless such modification is in writing and signed by all parties 
hereto. No waiver of any term of this Agreement shall be enforceable unless in 
writing and signed by the party against which it is sought to be enforced. The 
waiver by any party of a breach of any provision of this Agreement shall not 
operate or be construed as a waiver of any subsequent breach by such party.

        7.02.     Expenses. Each party shall bear its own expenses incurred in 
connection with the preparation of this Agreement and the consummation of the 
transactions contemplated hereby; provided, however, in connection with the

of December 31, 1997, each of ADT and Ultrak shall pay one-half of such fees 
and expenses.

        7.03.     Counterparts. This Agreement may be executed in two or more 
counterparts, all of which will be considered the same agreement and faxed 
copies of manually executed signature pages to this Agreement will be fully 
binding and enforceable without the need for delivery of the manually executed 
signature page.

LAWS RULES) OF TEXAS GOVERN THIS AGREEMENT.

signature block for each party to this Agreement.

        7.06.     Survival. All representations, warranties and covenants made 
by ADT and Ultrak herein or in any agreement, certificate or other instrument 
delivered by it hereunder shall be considered to have been relied upon by Ultrak
or ADT and shall survive the Closing, regardless of any investigation made by 
or on behalf of Ultrak or ADT.

        7.07.     Severability. If any provision of this Agreement is held to 
be illegal, invalid, or unenforceable, such provision shall be fully severable, 
and this Agreement shall be construed and enforced as if such illegal, invalid, 
or unenforceable provision were never a part hereof; the remaining provisions 
hereof shall remain in full force and effect and shall not be affected by the 
illegal, invalid, or unenforceable provision or by its severance; and in lieu 
of such illegal, invalid, or unenforceable provision, there shall be added 
automatically as part of this Agreement, a provision as similar in its terms to 
such illegal, invalid, or unenforceable provision as may be possible and be 
legal, valid, and enforceable.

        7.08.     Assignments; Entire Agreement; Headings. This Agreement shall 
not be assignable by operation of law or otherwise. Any attempted assignment of 
this Agreement shall be void. This Agreement, the Schedules attached hereto, and

other prior agreements and understandings, both written and oral, between the

                              EMPLOYMENT AGREEMENT


     THIS AGREEMENT is between Ultrak, Inc., a Delaware corporation (the
"Company"), and Ted Wlazlowski ("Employee").

     In consideration of the terms of this Agreement, and other good and
valuable consideration, the sufficiency of which is hereby acknowledged by each
party, the Company and Employee, intending to be legally bound, hereby covenant
and agree as follows:

     1.   Employment. The Company hereby agrees to employ Employee, and Employee
hereby accepts employment with the Company, upon the terms and conditions
hereinafter set forth.

     2.   Term. Subject to the other terms of this Agreement, this Agreement
shall be effective for the period (the "First Year") from January 1, 1998
through December 31, 1999. The period from January 1 of a calendar year through
December 31 of such calendar year is hereafter referred to as a "Year." The
period during which this Agreement is effective is hereafter referred to as the
"Term." The parties may, by mutual written agreement, extend the Term beyond
December 31, 1999.

     3.   Duties. Employee shall be the Executive Vice President of the Company.
During the Term, Employee shall be based in Lewisville, Texas or elsewhere in
the Dallas metropolitan area (to include Collin, Dallas, Denton, Ellis, Rockwall
and Tarrant counties) only and shall perform the duties and exercise the powers
which from time to time may be lawfully assigned to or vested in him by the
Company's Board of Directors (the "Board"). It is agreed that during the Term,
Employee will not accept an officership or directorship or participate in the
operation or management of any other entity, unless it is an entity either owned
or controlled by the Company, without the prior written consent of the President
of the Company.

     4.   Extent of Services. Unless prevented by ill health, Employee shall
devote his entire working time, attention and energies to the business of the
Company, and shall not during the Term engage in any other business activity
whether or not such business activity is pursued for gain, profit or other
pecuniary advantage; provided, however, Employee shall not be prevented from
investing in such form or manner as will not require any services on the part of
Employee in the operation of the affairs of the companies in which such
investments are made, except that in no event may Employee make investments in
any firms in competition with, or in the business of supplying goods or services
to the Company, unless such investments are (a) disclosed in writing to and
approved by the Board and (b) do not exceed $25,000 with respect to each
investment in any privately-held company or 2% of the voting securities of any
publicly-owned company.

     5.   Base Salary. The Company shall pay Employee a salary (the "Base
Salary"), payable in bi-weekly installments. The Base Salary per Year shall be
$180,000 and may be increased by the Board without an amendment to this
Agreement. If Employee is absent from
<PAGE>   2
his employment because of illness which prevents Employee from performing his
duties described herein, the Company shall be obligated to pay Employee his Base
Salary and other compensation for all such periods of absence for the balance of
the Term less any applicable disability insurance actually received by Employee.
The Base Salary and any other compensation payable pursuant to this Agreement
shall be subject to appropriate tax withholding.

     6.   Other Compensation and Benefits.

          (a)  The Company currently has in effect certain bonus and stock 
               option plans. During the Term, Employee will be eligible to
               participate in those plans currently in effect and as they may
               be amended from time to time, so long as such plans remain in
               existence. Furthermore, during the Term, Employee shall be
               entitled to participate in all current or subsequently enacted
               benefit programs applicable to all executive officers of the
               Company, including the Company's 401(k) plan. For purposes of
               this Agreement, all references to stock option plans, bonus plans
               or benefit programs shall be deemed to mean that Employee shall
               be eligible to participate in such plans or programs of the
               Company in which Employee presently participates or is eligible
               to participate, or such plans or programs that may subsequently

               responsible for paying for forty percent (40%) of the premiums
               for health insurance coverage. Employee understands such
               percentage may change.

          (e)  The Company will, on or about the date hereof, grant Employee an 
               option under Company's Stock Option Plan to purchase 20,000

          (f)  For the First Year, the Company guarantees that Employee's bonus 
               will be at least $75,000 assuming Employee is employed by the
               Company for the entire First Year (subject to sick days and
               vacation). Such bonus for the First Year will be payable on or
               about March 15, 1999.

          (g)  Employee acknowledges that certain of Employee's relocation 
               expenses will be reimbursed to Employee pursuant to the Ultrak
               Relocation Policy, a copy of which has previously been furnished
               to Employee. In addition to the reimbursement of Employee under

<PAGE>   3
               reimbursement of $10,000, for the amount by which (i) Employee's 
               basis in his main residence in the Chicago, Illinois area exceeds
               (ii) the [gross] [net] amount received by Employee in connection 
               with the sale, within a reasonable time prior to or following the
               date of this Agreement, of Employee's main residence in the 
               Chicago, Illinois area.

          (h)  Upon execution of this Agreement, Employee will receive a 
               one-time signing bonus of $25,000.

          (i)  The Company will pay for a fully furnished executive apartment 
               for Employee for up to a maximum of six (6) months from the date
               hereof. Employee's selection of the apartment will be subject to
               the Company's prior reasonable approval.

          (j)  If Employee's residence in the Chicago, Illinois area is sold 
               by Employee at a sales price of less than $290,000, then the 
               Company will allow Employee to elect to receive an advance 
               against the guaranteed bonus payable to Employee pursuant to 
               Section 6(f) in an amount not to exceed the lesser of (i) the 
               amount by which the sales price is less than $290,000 or (ii) 
               $75,000.

     7.   Expense Reimbursement. Employee is authorized to incur reasonable 
expenses with regard to the business of the Company, including expenses for 
entertainment, travel and other items of a similar character in accordance with 
the Company's travel and entertainment policies as such policies shall exist 
from time to time (the "Policy"). The Company will reimburse Employee for all 
such expenses incurred and reported by him in accordance with the Policy.

     8.   Termination by the Company. This Agreement may be terminated by the 
giving of sixty (60) days prior written notice pursuant to Section 13 by the 
Company:

               requiring him to cure such breach(es);

          (b)  If Employee shall be convicted of a criminal offense which in 
               the reasonable opinion of the Board may injure or tend to injure
               the reputation or business of the Company;

          (c)  If Employee files for bankruptcy or a bankruptcy petition is 
               filed against Employee and, in either case, such bankruptcy 
               proceeding is not dismissed within ninety (90) days of being 
               filed;

          (d)  If Employee shall grossly neglect the performance of his duties

          (e)  If Employee becomes so addicted to alcohol, drugs or any 
               controlled substance that it substantially impairs his abilities

     9.   Termination by the Company or Employee. Notwithstanding any other 
provision of this Agreement, either party may terminate this Agreement by

     10.  Payments upon Termination or Death. It is agreed that if this 
Agreement is terminated, payments and/or provisions for payments will be made 
as follows:

          (a)  If the Company terminates this Agreement on some basis other 
               than the reason or reasons as stated in Section 8, or if 
               Employee dies, the Company will take the actions set forth in
               parts (1), (2) and (3) of this Subsection 10(a). If Employee 
               terminates this Agreement for cause, which shall be limited to a 
               material breach (specified in writing by Employee) by the 
               Company of the terms of this Agreement, then the Company will 
               take the actions set forth in parts (1), (2) and (3) of this 
               Subsection 10(a).

               (1)  All stock options presently granted to Employee will become 
                    immediately vested and shall be exercised, if ever, in 
                    accordance with and subject to the terms and provisions of 
                    the Company's Stock Option Plan and Employee's Stock Option 
                    Agreement; and

               (2)  If Employee dies, Employee's estate will receive within 
                    fifteen (15) days, an amount equal to all Base Salary and 
                    all other benefits that would have accrued and/or been 
                    payable to Employee for a period of twelve (12) months from 
                    the date of death at Employee's then current level of 
                    compensation, and if the Company terminates this Agreement 
                    on some basis other than the reason or reasons stated in 
                    Section 8 or Employee terminates this Agreement for cause, 
                    Employee will continue to receive all Base Salary and all 
                    other benefits for a period of one year from the date of 
                    termination; and 
               
               (3)  Any other relocation or other expense amount specifically 
                    agreed to herein.

          (b)  If the Company terminates this Agreement for a reason or reasons 
               set forth in Section 8 or Employee terminates this Agreement 
               without cause, then the Company will only be obligated to pay to 
               Employee the actual amount of compensation accrued to the date 
               of termination, Employee will be bound to the terms of any Stock 
               Option Agreement as it relates to the exercise of any vested 
               stock options, and all other payments or benefits recited herein 
               shall be cancelled and terminated, without recourse.

the reason or reasons stated in Section 8 or Employee terminates this Agreement 
for cause, the Noncompete Period shall be the period after termination for

     14.  Waiver, Modification or Cancellation. Any waiver, amendment, 
modification, or cancellation of any provision of this Agreement shall not be 
valid unless in writing and signed by both Employee and the Company; provided, 
however, that increases in the Base Salary approved by the Board or the 
granting of additional compensation and/or benefits to Employee approved by the 
Board need not be in a writing signed by Employee.

     15.  Binding Effect. This Agreement shall inure to the benefit of and be 
binding upon (a) the Company and the Company's successors and assigns, 
including but not limited to any entity which may acquire all or substantially 
all of the Company's assets and business or with or into which the Company may 
be consolidated or merged, and (b) Employee and Employee's heirs, executors,
administrators and legal representatives, provided that the duties of Employee 
as described herein may not be delegated.

     16.  Severability. If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws, such provision
shall be fully severable and this Agreement shall be construed and enforced as
if such illegal, invalid or unenforceable provision never comprised a part
hereof; and the remaining provisions hereof shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom. Furthermore, in lieu of such illegal,
invalid or unenforceable provision, there shall be added automatically as part
of this Agreement, a provision as similar in its terms to such illegal, invalid
or unenforceable provision as may be possible and be legal, valid and
enforceable.
