                                    PART I

ITEM 1.   DESCRIPTION OF BUSINESS

                            HISTORY OF THE COMPANY

     GENERAL.  Boots & Coots International Well Control, Inc. (the "Company"),
formerly known as Havenwood Ventures, Inc. ("Havenwood"), was incorporated in
Delaware in April 1988.  Havenwood was originally formed to serve as a blind
pool investment fund, and in July 1988 Havenwood raised $499,500 in an initial
public offering of its common stock, par value $.00001 per share ("Common
Stock").  After completing its initial public offering, Havenwood expended its
available resources in the development of a business enterprise which it
ultimately divested, thereafter remaining inactive, with no material assets or
liabilities, until it entered into a business combination with IWC Services,
Inc. a Texas corporation ("IWC Services") on July 29, 1997.

     ACQUISITION OF IWC SERVICES, INC.  The Company acquired IWC Services on
July 29, 1997, in a "reverse triangular merger" in which it issued shares of
Common Stock to the stockholders of IWC Services in exchange for all of the
issued and outstanding common stock of IWC Services and issued options and
warrants to purchase Common Stock of the Company in exchange for all of the
options and warrants to purchase common stock of IWC Services then outstanding.
As a result of the merger, IWC Services became a wholly-owned subsidiary of the
Company, the stockholders of IWC Services became the beneficial holders of
approximately 93% of the post-merger issued and outstanding shares of Common
Stock and the board of directors and management of IWC Services took over the
management of the Company.

     IWC Services is a global-response oil and gas well control service company
that specializes in responding to and controlling oil and gas well emergencies,
including blowouts and well fires.  In addition, IWC Services provides snubbing
and other non-critical well control services.  IWC Services was organized in
June 1995 by six former key employees of the Red Adair Company who resigned
their positions after Mr. Adair retired and sold his business.

     ACQUISITION OF THE ASSETS OF BOOTS & COOTS, L.P.  On July 31, 1997, the
Company completed the acquisition of substantially all of the operating assets
of Boots & Coots, L.P., a Colorado limited partnership ("Boots & Coots") an oil
well firefighting, snubbing and blowout control services company.  In connection
with the acquisition of Boots & Coots, the Company acquired all interests of
Boots & Coots in its subsidiary corporations, Boots & Coots Overseas, Ltd., and
Boots & Coots de Venezuela, S.A. 

                                       1
<PAGE>
 
(collectively referred to herein as "Boots & Coots"). The consideration paid
consisted of (i) $369,432 cash, (ii) $680,568 placed in escrow to pay certain
debts of Boots & Coots, (iii) the issuance of secured promissory notes of the
Company in the aggregate principal amount of $4,760,977 and (iv) 259,901 shares
of Common Stock of the Company. The Company also granted registration rights for
the shares of Common Stock issued to Boots & Coots in the transaction.

     Boots & Coots was organized by Boots Hansen and Coots Mathews, two former
employees of the Red Adair Company who, like the founders of IWC Services, left
that firm to form an independent company, which was a primary competitor of
IWC Services.  As a consequence of the acquisition of Boots & Coots, the Company
became a leader in the worldwide oil well firefighting and blowout control
industry, reuniting many of the former employees of the Red Adair Company.

     ACQUISITION OF ABASCO, INC. On September 25, 1997, the Company completed
the acquisition of all of the capital stock of ABASCO, INC. ("ABASCO") which had
acquired the operating assets of American Boat and Skimmer Company, a recognized
leader in the design and manufacture of a comprehensive line of rapid-response
oil and chemical spill containment and reclamation equipment and products since
1975. ABASCO'S products and services include mechanical skimmers, containment
booms and boom reels, dispersant sprayers, agent absorbents, response vessels,
oil and chemical spill industrial products, spill response packages, oil and
chemical spill ancillary products and waste oil recovery and remediation
services. The Company acquired ABASCO for aggregate consideration consisting of
approximately $1,590,000 cash and 300,000 shares of Common Stock.

     ACQUISITION OF ITS SUPPLY CORPORATION. On January 2, 1998, the Company
completed the funding of the acquisition, effective as of December 31, 1997, of
all of the capital stock of ITS Supply Corporation ("ITS") for aggregate
consideration of $6,000,000. Financing for the acquisition of ITS was provided
from working capital ($500,000); and proceeds from the issuance of 10% Senior
Secured Promissory Notes ($4,500,000) and short-term bridge financing from the
seller ($1,000,000).

     ITS is an ISO 9002 certified materials and equipment procurement,
transportation and logistics company that serves the energy industry worldwide,
with offices in Houston, Venezuela, Peru, Dubai (UAE) and the United Kingdom.

     ACQUISITION OF CODE 3, INC. On February 20, 1998, the Company completed the
acquisition of all of the capital stock of Code 3, Inc. ("Code 3").
Consideration for the acquisition of Code 3, with an effective date for audited
purchase price adjustments of December 31, 1997, was (i) $570,568 cash, (ii) the
repayment of corporate secured debt and interest thereon of approximately
$1,250,000 through closing, and (iii) the issuance of 488,136 shares of the
Company's Common Stock, of which 158,646 shares were delivered into escrow to
secure the indemnification obligations of the stockholders of Code 3 for claims
that may arise as a consequence of a breach by such stockholders or Code 3 of
the representations, warranties and covenants contained in the definitive
agreements.

     Code 3, originally headquartered in Harlingen, Texas, provides containment
and remediation of hazardous material and oil spills for the railroad,
transportation and shipping industries, as well as various state and federal
governmental agencies.  Code 3 also specializes in the transfer of hazardous
materials and high and low pressure liquids and industrial fire fighting and
provides in-plant remedial plan implementation, hazardous waste management,
petroleum tank management, industrial hygiene, environmental and occupational,
health and safety services.  Through December 31, 1997, Code 3 operated out of
facilities in Harlingen, El Paso, Laredo, San Antonio and Houston, Texas.
Current expansion plans for additional emergency response facilities and
equipment include Ft. Worth, Texas, and Denver, Colorado.

                                    BUSINESS

     INDUSTRY OVERVIEW

     The oil and gas industry has enjoyed a sustained resurgence over the last
several years due to improved market conditions.  The fundamental supply and
demand balance for oil and gas products began to shift in late 1992 and has
continued to improve with increased global demand for petroleum products.
Historically, the oil and gas cycle has been characterized by alternating "boom"
and "bust" periods that typically last for 12 to 14 years.  The last down cycle
began in 1981 and continued through 1992, when signs of recovery began, and by
1995, the current recovery cycle had been confirmed.  Although oil and natural
gas prices have recently softened, management believes that the fundamental
market statistics and trends strongly suggest that the oil and gas business
cycle, though not likely to be at a historical "boom" level, will be favorable
over the next 10 years.

     The three major segments on the production side of the oil and gas industry
have generally experienced the effects of the "boom" and "bust" cycle in
distinctly different time frames.  The first group to experience the effects of
cycle changes consists of exploration and production companies who plan their
drilling and development activities on the basis of current and anticipated oil
and gas prices.  The next group to experience the effects of cycle changes
consists of oil and gas service providers, including seismic companies, contract
drilling companies, and other companies that provide pipe and drill bits,
together with logging, cementing, and other services.  The last group to
experience the effects of cycle changes consists of equipment manufacturers who
are usually the last to recover when oil and gas prices increase and the first
to decline when oil and gas prices decline. During the past two years, for the
first time since 1982, plans were announced for the construction of a meaningful
number of new offshore drilling rigs.

     Drilling activity increased in 1996 and in 1997, which, combined with
increased drilling activities since 1993, equates to increased numbers of wells
coming on line. Although drilling technology has improved in recent years,
thereby reducing the likelihood of a major well control event, several industry
conditions tend to offset this factor. Relatively old drilling equipment
(although generally well maintained) continues to be used. There have been few
new land or offshore drilling rigs constructed since 1981 because rig rental
rates have been insufficient to justify the required capital investment. Current
worldwide utilization rates for offshore drilling rigs are at substantially full
capacity for marketable rigs and utilization for land drilling rigs is
increasing. Several contract drilling companies are experiencing problems hiring
experienced crews, prices for new drill pipe have increased significantly and
delivery schedules have been extended. These factors together with an increased
number of producing wells requiring workover operations, tend to increase the
likelihood of a major well control event. In addition, existing environmental
constraints in the U.S. and increasing awareness of environmental issues in
developing countries will require operators to emphasize training, safety and
contingency planning for potential blowout or other well control events.

                                       3

     THE EMERGENCY RESPONSE SEGMENT OF THE OIL AND GAS SERVICE INDUSTRY

     History. The emergency response segment of the oil and gas services
industry traces its roots to the late 1930's when Myron Kinley organized the
Kinley Company, the first oil and gas well firefighting specialty company.
Shortly after organizing the Kinley Company, Mr. Kinley took on an assistant
named Red Adair who learned the firefighting business under Mr. Kinley's
supervision and remained with the Kinley Company until Mr. Kinley's retirement.
When Mr. Kinley retired in the late 1950's, Mr. Adair organized the Red Adair
Company and subsequently hired Boots Hansen, Coots Mathews and Raymond Henry as
members of his professional firefighting staff. Mr. Adair added Richard
Hatteberg, Danny Clayton, Brian Krause, Mike Foreman and Juan Moran to his
professional firefighting staff and the international reputation of the Red
Adair Company grew to the point where it was a subject of popular films and the
dominant competitor in the industry. Boots Hansen and Coots Mathews remained
with the Red Adair Company until 1978 when they split off to organize Boots &
Coots, an independent firefighting, snubbing and blowout control company.

     Historically, the well control emergency response segment of the oil and
gas services industry has been reactive, rather than proactive, and a small
number of Houston-based companies have dominated the market.  As a result, if an
operator in Indonesia, for example, experienced a well blowout and fire, he
would likely call a well control emergency response company in Houston that
would take the following steps:

  *  Immediately dispatch a control team to the well location to supervise
     debris removal, local equipment mobilization and site preparation;

  *  Gather and analyze the available data, including drilling history, geology,
     availability of support equipment, personnel, water supplies and ancillary
     firefighting resources;

  *  Develop or implement a detailed fire suppression and well-control plan;

  *  Mobilize additional well-control and firefighting equipment in Houston;

  *  Air freight equipment from Houston to the blowout location;

  *  Extinguish the fire and bring the well under control; and

  *  Transport the control team and equipment back to Houston.

   On a typical blowout, debris removal, fire suppression and well control can
require several weeks of intense effort and consume millions of dollars,
including several hundred thousand dollars in air freight costs alone.

   The 1990's have been a period of rapid change in the oil and gas well control
and firefighting business. The hundreds of oil well fires that were started by
Iraqi troops during their retreat from Kuwait spurred the development of new
firefighting techniques and tools that have become industry standards. Moreover,
after extinguishing the Kuwait fires, the entrepreneurs who created the oil and
gas well firefighting industry, including Red Adair, Boots Hansen and Coots
Mathews retired, leaving the Company's senior staff as the most experienced
active oil and gas well firefighters in the world. At present, the principal
competitors in the oil and gas well firefighting business are the Company, Wild
Well Control, Inc., and Cudd Pressure Control, Inc.

   Emerging Trends.  Corporate downsizing and outsourcing of services, when
coupled with increased recognition of the importance of training, environmental
protection and emergency preparedness, are 

                                       4
<PAGE>
 
having a profound impact on the emergency response segment of the oil and gas 
services industry. Instead of waiting for a blowout, fire or other disaster to
occur, major oil producers are coming to the Company for proactive preparedness
and incident prevention programs, together with pre-event consultation on
matters relating to well control training, blowout contingency planning, on-site
safety inspections and formal fire drills.

   In addition to seeking pre-event consulting services, a number of major oil
and gas producers have come to the realization that servicing the worldwide
firefighting and well control market from Houston is inefficient: the response
time is too long and the cost of transporting equipment by air freight is
prohibitive.  As a result, the Company has recently entered into an agreement to
establish and maintain an industry supported "Fire Station" on the North Slope
of Alaska.  Under the terms of the agreement, the Company has sold to a
consortium of producers the equipment required to respond to a blowout or oil or
gas well fire, and has agreed to maintain the equipment and conduct on-site
safety inspections and emergency response drills.  Over the next five years, the
Company plans to establish a worldwide network of Company owned Fire Stations
and to use this global presence as the foundation to seek to establish a
preeminent position in the oil and gas well firefighting business.

   VOLATILITY OF FIREFIGHTING REVENUES. The market for oil and gas well
firefighting and blowout control services is highly volatile due to factors
beyond the control of the Company. While the demand for firefighting and blowout
control services ordinarily follows predictable trends in the oil and gas
industry, extraordinary events such as the Bay Marchand and Piper Alpha
disasters have historically occurred only every four to six years. Wars, acts of
terrorism and other unpredictable factors may increase the need for oil and gas
well firefighting and blowout control services from time to time. As a result,
the Company can expect to experience large fluctuations in its revenues from oil
and gas well firefighting and blowout control services. While the Company
believes that its acquisitions of ABASCO, ITS and Code 3 and anticipated
revenues from the WELLSURE(SM) program and from the Company's consulting,
snubbing, training and industrial and marine firefighting services will help to
provide an expanded and predictable revenue and earnings base in the future,
there can be no assurance that the Company will be successful in further
developing these acquired businesses and added services. Accordingly, the
Company expects that its revenues and operating performance may vary
considerably from year to year for the foreseeable future.

   SERVICES PROVIDED BY THE COMPANY

   The Company is a global-response oil and gas service company that specializes
in responding to and controlling oil and gas well emergencies, including
blowouts and well fires.  In connection with such services, the Company has the
capacity to supply the equipment, expertise and personnel necessary to contain
the oil and hazardous materials spills and discharges associated with such oil
and gas well emergencies, to remediate affected sites and to restore affected
oil and gas wells to production. In addition to providing emergency response
services, the Company provides snubbing, well plugging and abandonment and other
non-critical well control services, including pre-event planning, training and
consulting services. The Company also manufactures and markets oil and hazardous
materials spill containment and recovery equipment. The Company provides
environmental remediation services to the chemical manufacturing and
transportation industries, as well as to various state and federal agencies, and
also provides materials and equipment procurement, transportation and logistics
services to the energy industry. The Company's principal services lines include:

   Well Control.  This service line is divided into two distinct service levels:
(1) "Critical Event" response is ordinarily reserved for well control projects
where hydrocarbons are escaping from a well bore, regardless of whether a fire
has occurred.  (2) "Non-critical Event" response, on the other hand, is intended
for the more common operating problems that do not involve escaping
hydrocarbons.

                                       5
<PAGE>
 
     Critical Events. Critical Events frequently result in explosive fires, the
     loss of life, the destruction of drilling and production facilities,
     substantial environmental damage and the loss of hundreds of thousands of
     dollars per day in production revenue. Since Critical Events ordinarily
     arise from equipment failures or human error, it is impossible to
     accurately predict the timing or scope of the Company's Critical Event
     work. Notwithstanding the foregoing, a Critical Event of catastrophic
     proportions could result in revenues to the Company well in excess of
     $5,000,000 in the year of the incident. The Company's professional
     firefighting staff has more than 220 years of aggregate industry experience
     in responding to Critical Events, oil and gas well fires and blowouts.

     Non-critical Events. Non-critical Events frequently occur in connection
     with the drilling of new wells into high pressure reservoirs. In most Non-
     critical Events, the blowout preventers and other safety systems on the
     drilling rig function according to design and the Company is then called
     upon to supervise and assist in the well control effort so that drilling
     operations can resume as promptly as safety permits. While Non-critical
     Events do not ordinarily have the revenue impact of a Critical Event, they
     are much more common and predictable.

     Equipment Rentals.  This service line includes the rental of specialty well
control and firefighting equipment by the Company primarily for use in
conjunction with Critical Events.  Such equipment includes, but is not limited
to, firefighting pumps, pipe-racks, Athey Wagons, pipe cutters, crimping tools
and deluge safety systems.  The Company charges this equipment out on a per diem
basis.  Past experience indicates that rentals can be expected to average
approximately 40% of the revenues associated with a Critical Event.

     Equipment Sales and Service. This service line involves the sale of
complete firefighting equipment packages, together with maintenance, monitoring,
updating of equipment and ongoing consulting services. A typical example of this
service line is the industry supported Fire Station that the Company has
established on the North Slope of Alaska. The establishment of this Fire
Station, completed during the six month period ended December 31, 1997, included
the sale of approximately $485,000 in equipment. The Company has also entered
into a long-term agreement to provide ongoing consulting services relating to
the Fire Station, including training, contingency planning, safety inspections
and emergency response drills. The Company believes that the follow-on revenue
from the North Slope Fire Station may approximate $100,000 per year.

     Snubbing Operations.  A snubbing unit is a high pressure workover rig that
permits an operator to repair or change-out damaged casing, production tubing
and down-hole production equipment in a high pressure environment.  Using a
series of highly sophisticated blowout prevention devices, a snubbing unit makes
it possible to remove and replace down-hole equipment in a pressurized well.
Since snubbing is a very hazardous process that entails a high risk of flash
fire or explosion, the snubbing segment of the oil and gas services industry is
concentrated in a few competitors who have the experience and knowledge required
to safely and efficiently perform such services.

     Industrial and Marine Firefighting.  This service line is divided into two
distinct elements: pre-event consulting and Critical Event management.  The pre-
event services offered in the industrial and marine firefighting business
include complete on-site inspection services, safety audits and pre-event
planning.  Based on these pre-event services, the Company can recommend the
equipment, facilities and manpower resources that a client should have available
in order to effectively respond to a fire.  The Company can also consult with
the client to insure that the equipment and services required by the client will
be available when needed.  If a Critical Event subsequently occurs, the Company
is ready to respond at a client's facility with experienced firefighters and
auxiliary equipment.

     Oil and Chemical Spill Containment and Reclamation Equipment. The Company
is a leader in the design and manufacture of a comprehensive line of rapid
response oil and chemical spill containment and reclamation equipment and
products, including mechanical skimmers, containment booms and boom reels,
dispersant sprayers, dispersal agents, absorbents, response vessels, oil and
chemical spill industrial products, spill response packages, oil and chemical
spill ancillary products and waste oil recovery and reclamation products.

     Oil and Chemical Spill Containment and Remediation Services. The Company's
ABASCO business unit provides containment and remediation of oil and chemical
spills for the oil and gas, petrochemical, railroad, transportation and shipping
industries, as well as various state and federal governmental agencies. Code 3
specializes in the transfer of high and low pressure liquids and hazardous
materials and industrial fire fighting. Code 3 also provides in-plant remedial
plan implementation, hazardous waste management, petroleum tank management,
industrial hygiene, environmental and occupational, health and safety services.

     Supply, Transportation and Logistics. The Company's ITS business unit is
ISO 9002 certified and provides material and equipment procurement,
transportation and logistics services to the energy industry worldwide.
 
     Consulting; Drilling Engineering.  The Company has the ability to provide
through its highly-specialized in-house engineering staff, supplemented if
necessary by outside engineering consultants and the Halliburton Energy Services
division, engineering services for such areas as: (1) planning and design of
relief well drilling (trajectory planning, directional control and equipment
specifications, and on-site supervision of the drilling operations), (2)
planning and design of production facilities which are susceptible to well
capping or other control procedures, and (3) mechanical and computer aided
designs for well control equipment.
 
     Consulting; Inspections.  A cornerstone of the Company's strategy of
providing preventive well control services involves on-site inspection services
for drilling and workover rigs, drilling and production platforms, and field
production facilities.  Since these inspection services will be offered as a
standard option in Halliburton's field service programs, the Company anticipates
that inspection services will become an important source of revenue.
 
     Consulting; Training.  The Company provides specialized training in well
control procedures for drilling, exploration and production personnel.  To date
such training programs have been provided for both U.S. and international
operators.  Since the Company's training services will be offered in conjunction
with ongoing educational programs sponsored by Halliburton, the Company believes
the training segment of its business offers considerable potential for growth.

     Strategic Event Planning (S.T.E.P.).  A key element of the services offered
by the Halliburton Alliance is a strategic and tactical planning process
addressing action steps, resources and equipment necessary for an operator to
control a blowout.  This planning process incorporates organizational
structures, action plans, specifications, people and equipment mobilization
plans with engineering details for well firefighting, capping, relief well and
kill operations.  It also addresses optimal recovery of well production status,
insurance recovery, public information and relations and safety/environmental
issues.  While the S.T.E.P. program includes a standardized package of services,
it is easily modified to suit the particular needs of a specific client.

     Regional Fire Stations. The Company, in conjunction with Halliburton, plans
to pre-position in selected geographic locations throughout the world complete
complements of specialty firefighting equipment and ancillary tools and
equipment ("Fire Stations"). The equipment for these proposed Fire Stations will
either be purchased by the Company for its own account, using cash flow, if any,
from operations, or purchased by a consortium of local producers who will then
contract with the Company for

                                       7
<PAGE>
 
maintenance and consulting services. The Company currently has Fire Stations in
Houston, Texas, Duncan, Oklahoma, and Anaco, Venezuela, and maintains an
industry supported Fire Station on the North Slope of Alaska. The Company plans
to deploy at least one Fire Station per year over the next five years. It is
believed these Fire Stations, once established, will place the Company and its
Wellcall Alliance with Halliburton in an unique competitive position within the
industry and allow the alliance to gain market share by reducing the
mobilization time and costs traditionally involved in controlling major blowout
events.

   WELLSURE (SM) Program.  On February 6, 1998, the Company announced the
formation of an alliance with Global Special Risks, Inc., a managing general
insurance agent located in Houston, Texas, and New Orleans, Louisiana.  The
alliance offers oil and gas exploration and production companies, through retail
insurance brokers, a new program known as "WELLSURE (SM)," which combines
traditional well control and blowout insurance with the Company's post-event
response services and well control preventative services including company-wide
and/or well specific contingency planning, personnel training, safety
inspections and engineering consultation.  Insurance provided under WELLSURE
(SM) has been arranged with leading London insurance underwriters.  WELLSURE
(SM) program participants will be provided with the full benefit of having the
Company as a safety and prevention partner.  In the event of well blowouts, the
Company will serve as the integrated emergency response service provider, as
well as function as lead contractor and project manager for control and
restoration of wells covered under the program.

     HALLIBURTON ALLIANCE

     In response to ongoing changes in the emergency response segment of the oil
and gas service industry, the Company entered into a global strategic alliance
with Halliburton Energy Services. Halliburton is widely recognized as an
industry leader in the pumping, cementing, snubbing, production enhancement,
coiled tubing and related services segment of the oil field services industry.
This alliance, "WELLCALL (SM)", draws on the expertise and abilities of both
companies to offer a total well control solution for oil and gas producers
worldwide. The Halliburton Alliance provides a complete range of well control
services including pre-event troubleshooting and contingency planning, snubbing,
pumping, blowout control, debris removal, firefighting, relief and directional
well planning and other specialized services. The specific benefits that
WELLCALL (SM) provides to an operator include:

     *    Quick response with a global logistics system supported by an
          international communications network that operates around the clock,
          seven days a week;

     *    A full-time team of experienced well control specialists that are
          dedicated to safety;

     *    Specialized equipment design, rental, and sales;

     *    Contingency planning consultation where WELLCALL (SM) specialists meet
          with customers, identify potential problems, and help develop a
          comprehensive contingency plan; and

     *    A single-point contact to activate a coordinated total response to
          well control needs.

     Operators contracting with WELLCALL (SM) receive a Strategic Event Plan, or
S.T.E.P., a comprehensive contingency plan for well control that is region-
specific, reservoir-specific, site-specific and well-specific.  The S.T.E.P.
plan provides the operator with a written, comprehensive and coordinated action
plan that incorporates historical data, pre-planned call outs of Company and
Halliburton personnel, pre-planned call outs of necessary equipment and
logistical support to minimize response time and coordinate the entire well
control effort.  Thereafter, in the event of a blowout, WELLCALL (SM) provides

                                       8
<PAGE>
 
the worldwide engineering and well control equipment capabilities of Halliburton
and the firefighting expertise of the Company through an integrated contract
with the operator.

     As a result of the Halliburton Alliance, the Company is directly involved
in Halliburton's well control projects that require firefighting expertise,
Halliburton is a primary service vendor to the Company and the Company has
exclusive rights to use certain firefighting technologies developed by
Halliburton. It is anticipated that most of the Company's Fire Stations will be
established at existing Halliburton facilities and that maintenance of the Fire
Station equipment will be performed by Halliburton employees. The Halliburton
Alliance also gives the Company access to Halliburton's global communications
and currency management systems, capabilities that could prove invaluable in
connection with the Company's international operations.

     Consistent with the Halliburton Alliance, the Company's focus has evolved
to meet its clients' needs in a global theater of operations. With the increased
emphasis by operators on operating efficiencies and outsourcing many engineering
services, the Company has developed a proactive menu of services to meet their
needs. These services emphasize pre-event planning and training to minimize the
likelihood of a blowout and minimize damages in the event of an actual blowout.
The Company provides comprehensive advance training, readiness, preparation,
inspections and mobilization drills which allow client companies to pursue every
possible preventive measure and to react in the most cohesive manner possible
when an event occurs. The Halliburton Alliance stresses the importance of
safety, environmental protection and cost control, along with asset protection
and liability minimization.

     The agreement documenting the alliance between the Company and Halliburton
(the "Alliance Agreement") provides that it will remain in effect for an
indefinite period of time and may be terminated prior to September 15, 2000,
only for cause, or by mutual agreement between the parties.  Under the Alliance
Agreement, cause for termination is limited to (i) a fundamental breach of the
Alliance Agreement, (ii) a change in the business circumstances of either party,
(iii) the failure of the Alliance to generate economically viable business, or
(iv) the failure of either party to engage in good faith dealing.  While the
Company considers its relationship with Halliburton to be good, there can be no
assurance that the Alliance Agreement will not be terminated by Halliburton.
The termination of the Alliance Agreement could have a material adverse effect
on the Company's future operating performance.

     BUSINESS STRATEGY

     Over the next few years, the Company intends to continue to expand its
operations and to build upon its demonstrated strengths while increasing
revenues from its consulting, equipment sales, environmental containment and
remediation services and Non-critical Event activities.  Recognizing that the
well control services business is a finite market whose upside potential is
dependent upon the occurrence of blowouts which cannot be reasonably predicted,
the Company's business strategy is to market its pre-event services on a global
basis and expand its range of services to establish a diversified and expanded
revenue base.  The Company intends to accomplish its objectives by promoting the
Halliburton Alliance and the WELLSURE (SM) program, continuing to integrate the
businesses of Boots & Coots, ABASCO, ITS and Code 3, increasing the geographical
scope of its training and consulting programs, and establishing additional
Company-owned Fire Stations at locations outside the United States.  Like the
Company owned Fire Stations in Houston, Texas, and Duncan, Oklahoma, the
industry supported Fire Station on the North Slope of Alaska and the Fire
Station in Anaco, Venezuela, the proposed Company-owned Fire Stations would
include the equipment required to respond to a well blowout or fire.  In
general, the Company plans to offer a broader range of services to oil and gas
producers worldwide, increasing both the scope of its target and its market
share.

                                       9
<PAGE>
 
     The Company hopes to expand its service capabilities through a combination
of internal growth, additional acquisitions, joint ventures and strategic
alliances. Because of the fragmented nature of the oil and gas services
industry, the Company believes a number of attractive acquisition opportunities
exist in the pressure control, emergency response and environmental services
segments of the business. The oil and gas services business in general, and the
emergency response and environmental remediation segments in particular, are
characterized by a small number of dominant global competitors and a significant
number of locally oriented businesses, many of which tend to be viable
acquisition targets. The Company believes that the owners of locally oriented
companies may be willing to consider becoming part of a larger organization.

     Management has recently commenced preliminary discussions with a number of
companies engaged in complementary businesses to explore the potential for
mutually beneficial business arrangements.  While none of these discussions has
progressed to the point where the Company believes a particular transaction is
probable, management believes that additional acquisitions, joint ventures and
strategic alliances are likely.

     RESEARCH AND DEVELOPMENT

     The Company is not directly involved in activities that will require the
expenditure of substantial sums on research and development.  The Company does,
however, as a result of the Halliburton Alliance, benefit from the ongoing
research and development activities of Halliburton to the extent that new
Halliburton technologies are or may be useful in connection with the Company's
business.

     COMPETITION

     The emergency response segment of the oil and gas services business is a
rapidly evolving field in which developments are expected to continue at a rapid
pace.  The Company believes that the Halliburton Alliance, the WELLSURE (SM)
program, and its recent acquisitions of Boots & Coots, Abasco, ITS and Code 3
will strengthen its competitive position in the industry by expanding the scope
of services that the Company offers to its customers.  However, the Company's
ability to compete depends upon, among other factors, increasing industry
awareness of the variety of services the Company offers, expanding the Company's
network of Fire Stations and further expanding the breadth of its available
services.  Competition from other emergency response companies, some of which
may have greater financial resources than the Company, is intense and is
expected to increase as the industry undergoes additional anticipated change.
The Company's competitors may also succeed in developing new techniques,
products and services that are more effective than any that have been or are
being developed by the Company or that render the Company's techniques, products
and services obsolete or noncompetitive.  The Company's competitors may also
succeed in obtaining patent protection or other intellectual property rights
that might hinder the Company's ability to develop, produce or sell competitive
products or the specialized equipment used in its business.

     EMPLOYEES

     As of March 23, 1998, the Company and its operating subsidiaries
collectively had 183 full-time employees. In addition, the Company has several
part-time consultants and also employs part-time contract personnel who remain
on-call for certain emergency response projects. The Company is not subject to
any collective bargaining agreements and it considers its relations with its
employees to be good.

                                       10
<PAGE>
 
     OPERATING HAZARDS; LIABILITY INSURANCE COVERAGE; LITIGATION

     The Company's operations involve ultra-hazardous activities that involve an
extraordinarily high degree of risk.  Such operations are subject to accidents
resulting in personal injury and the loss of life or property, environmental
mishaps and mechanical failures, and litigation arising from such events may
result in the Company being named a defendant in lawsuits asserting large
claims.  The Company may be held liable in certain circumstances, including if
it fails to exercise reasonable care in connection with its activities, and it
may also be liable for injuries to its agents, employees and contractors who are
acting within the course and scope of their duties.  The Company and its
subsidiaries presently maintain liability insurance coverage with aggregate
policy limits which are believed to be adequate for their respective operations.
However, it is generally considered economically unfeasible in the oil and gas
service industry to maintain insurance sufficient to cover large claims.
Accordingly, there can be no assurance that the Company's insurance will be
sufficient or effective under all circumstances or against all hazards to which
the Company may be subject.  A successful claim for which the Company is not
fully insured could have a material adverse effect on the Company.  No assurance
can be given that the Company will not be subject to future claims in excess of
the amount of insurance coverage which the Company deems appropriate and
feasible to maintain.

     RELIANCE UPON OFFICERS, DIRECTORS AND KEY EMPLOYEES

     The Company's emergency response services require highly specialized
skills. Due to the unique nature of the industry and the small number of persons
who possess the requisite skills and experience, the Company is highly dependent
upon the personal efforts and abilities of its officers, directors and key
employees. In seeking qualified personnel, the Company will be required to
compete with companies having greater financial and other resources than the
Company. Since the future success of the Company will be dependent upon its
ability to attract and retain qualified personnel, the inability to do so, or
the loss of personnel, could have a material adverse impact on the Company's
business.

     CONTROL OF THE COMPANY BY SIGNIFICANT STOCKHOLDERS

     The Company's current officers and directors own beneficially, on a
combined basis, 10,943,473 shares of Common Stock, including currently
exercisable options to purchase Common Stock. The shares of Common Stock owned
by the Company's current officers and directors represent, in the aggregate,
approximately 35.79% of the issued and outstanding Common Stock.  As a
result, the current officers and directors of the Company collectively have
significant and perhaps controlling influence in the election of the Company's
Board of Directors and with respect to the determination and authorization of
corporate actions for an indefinite period of time. Further, in May 1995, Brian
Krause, the Company's President, Raymond Henry, the Company's Director of Well
Control Operations, Richard Hatteberg, the Company's Senior Vice President, Well
Control, and Danny Clayton, the President of IWC de Venezuela, entered into a
Voting Trust Agreement that gives Larry H. Ramming, the Company's Chairman and
Chief Executive Officer, and Mr. Henry, as co-trustees, the absolute right to
vote all shares of Common Stock now owned or hereafter acquired by Messrs.
Krause, Henry, Hatteberg and Clayton during the five-year period ending December
31, 2000 (the "Voting Trust Agreement"); provided, that twenty percent of the
shares subject to such agreement are eligible for release therefrom on each one
year anniversary date of the Voting Trust Agreement upon the written request of
the party owning such shares. In the event that Messrs. Ramming and Henry are
unable to reach an agreement respecting the voting of such shares, the Voting
Trust Agreement designates Charles T. Phillips, attorney at law, as the
tiebreaker.

     CONTRACTUAL OBLIGATIONS TO CUSTOMERS; INDEMNIFICATION

     The Company customarily enters into service contracts with its customers
which frequently contain provisions that hold the Company liable for various
losses or liabilities incurred by the customer in connection with the activities
of the Company, including, without limitation, losses and liabilities relating
to claims by third parties, damage to property, violation of governmental laws,
regulations or orders, injury or death to persons, and pollution or
contamination caused by substances in the Company's possession or control.  The
Company may be responsible for any such losses or liabilities caused by
contractors retained by the Company in connection with the provision of its
services.  In addition, such contracts generally require the Company, its
employees, agents and contractors to comply with all applicable laws, rules and
regulations (which may include the laws, rules and regulations of various
foreign jurisdictions) and to provide sufficient training and educational
programs to such persons in order to enable them to comply with applicable laws,
rules and regulations.  Consequently, the Company may be exposed to substantial
liabilities in connection with its services.  In the case of emergency response
services, the Company frequently enters into agreements with customers which
limit the Company's exposure to liability and/or require the customer to
indemnify the Company for losses or liabilities incurred by the Company in
connection with such services, except in the case of willful misconduct by the
Company.  There can be no assurance, however, that such contractual provisions
limiting the liability of the Company will be enforceable in whole or in part
under applicable law.

ITEM 2.   DESCRIPTION OF PROPERTY.

     REAL PROPERTY

     The Company leases a 7,000 square foot office in the Halliburton Center,
Houston, Texas.  This space is rented from an unaffiliated landlord through May
2002 for an average monthly rental of $7,000.  The Company leases an 11,000
square foot Fire Station facility in Anaco, Venezuela, which space is rented
through January 2000 for a monthly rental of $4,476. The Company owns a facility
in northwest Houston, Texas, that includes approximately 2 acres of land, a
4,000 square foot office building and a 12,000 square foot manufacturing and
warehouse building. The Company's ITS business unit leases approximately 10,000
square feet of office space in the Camac Plaza, Houston, Texas, through June 30,
1999, for an average monthly rental of $9,400. Additionally, ABASCO, ITS and
Code 3 have leased office and equipment storage facilities in various other
cities within the United States, Venezuela, the United Kingdom and Peru. The
future commitments on such leases are immaterial. The Company believes that
these facilities will be adequate for its anticipated needs.

     EQUIPMENT

     The Company is well-equipped for its current operations.  In the fields of
oil and gas well blowout control and firefighting specifically, the Company owns
five complete sets of oil-well firefighting equipment, including Athey wagons,
pumps, water lines, monitors and nozzles. These equipment sets are presently
located at Company-owned Fire Stations in Houston, Texas, Duncan, Oklahoma and
Anaco, Venezuela, and are in good condition. In addition, the Company has the 
in-house capacity to assemble additional firefighting and pump equipment 
packages as needed.

ITEM 3.   LEGAL PROCEEDINGS.

     The Company is not a party to any pending legal proceeding, nor is its
property the subject of a pending legal proceeding, which is not routine
litigation incidental to its business or in which the amount involved, exclusive
of interest and costs, exceeds ten percent of the current assets of the Company.

                                    PART II

ITEM 5.   MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

     The Company's Common Stock is traded on the AMEX under the symbol "WEL."
Prior to January 30, 1998, the Company's Common Stock was traded on the NASD's
OTC Electronic Bulletin Board under the symbol "BCWC".  Significant trading in
the Company's Common Stock has occurred only since August 1997.  The following

</TABLE>

     On March 23, 1998, the last reported sale price of the Common Stock as
reported on AMEX was $5.00 per share.

     The bid information has been provided by National Quotation Bureau, Inc.,
and reflects inter-dealer prices, without retail mark-up, mark-down or
commission, and may not represent actual transactions. As of March 20, 1998 the
Company's Common Stock was held by approximately 255 holders of record. The
Company estimates that it has a significantly larger number of shareholders
because a substantial number of the Company's shares are held of record by
broker-dealers for their customers in street name.

     The Company has not paid any cash dividends on its Common Stock to date.
The Company's current policy is to retain earnings to provide funds for the
operation and expansion of its business. Additionally, subsequently to December
31, 1997, the Company obtained short-term secured financing in the aggregate
amount of $7,250,000, which comes due between May 2, 1998 and June 15, 1998 (the
"Senior Notes"). The Company is prohibited from paying cash dividends as long as
the Senior Notes remain outstanding.

</TABLE> 

    Comparison of Year Ended June 30, 1996 with Year Ended June 30, 1997

    Revenues were $1,662,121 for the year ended June 30, 1996 ("fiscal 1996") 
compared to $2,564,087 for the year ended June 30, 1997 ("fiscal 1997"). This 
increase was the result of increased market share from diversification of IWC 
Service's client base.

    Operating expenses were $1,320,702 for fiscal 1996, compared to $1,459,640 
for fiscal 1997. The increase was the result of expanded operations in the 
fourth quarter of fiscal 1997 due to expanded business activity.

     General and administrative expenses were $772,626 for fiscal 1996, compared
to $1,061,259 for fiscal 1997. The increase was primarily the result of 
investments in expanded corporate infrastructure and expanded marketing and 
advertising to increase market share and diversify the Company's client base.

     Depreciation and amortization expense increased from $49,893 for fiscal
1996, compared to $111,469 for fiscal 1997, primarily as the result of a full
year of depreciation on equipment additions made in fiscal 1996.

     Other income (expenses) was $4,216 for fiscal 1996, compared to a net 
expense of ($62,774) for fiscal 1997, resulting primarily from higher interest 
expense on financed equipment purchases made during the 1996 period and interest
expense on the 12% Senior Subordinated Notes sold through June 30, 1997.

     Income taxes for fiscal 1996, includes a credit for the reversal of a 
deferred federal income tax provision of $139,000 for the 1995 start-up period. 
Substantially all of the balance of income taxes for both fiscal 1996 and fiscal
1997 represents foreign taxes withheld on various international projects.

     IWC Services sustained a net loss of $339,066 for fiscal 1996, compared to 
a net loss of $155,624 for the comparable period in 1997 as a result of the 
revenue and expense variations discussed above.

     Comparison of Six Months Ended December 31, 1996 with Six Months Ended 
     December 31, 1997

     Revenues were $743,040 for the six months ended December 31,1996 ("1996
Interim Period") compared to $5,389,137 for the six months ended December 31,
1997 ("1997 Interim Period"). This increase principally resulted from: (1)
product sales from the ABASCO acquisition completed in September 1997
($971,538); (2) sales of two fire fighting equipment packages in the 1997
Interim Period ($907,933); and, (3) increased market share for the Company's
Well Control business unit.

     Operating expenses were $730,890 for the 1996 Interim Period compared to 
$3,785,787 for the 1997 Interim Period. This increase principally resulted from:
(1) cost of sales and operating expenses from the ABASCO acquisition completed
in September 1997; ($632,176); (2) costs associated with the sales of two fire
fighting equipment packages in the 1997 Interim Period ($685,837); (3) personnel
and equipment mobilizations costs incurred in connection with an international
well control incident in October 1997 ($540,000); and, (4) costs associated with
an increase in personnel and support facilities resulting from the July 31, 1997
acquisition of the Boots & Coots operating assets and growth in the Company's
Well Control business unit.

     General and administrative expenses were $370,694 for the 1996 Interim 
Period compared to $1,535,890 for the 1997 Interim Period. This increase 
principally resulted from: (1) expenses associated from the ABASCO acquisition 
completed in September 1997 ($246,040); and, (2) expenses associated with an 
increase in personnel and other overhead to support the Company's increased 
operational level in Well Control.

     Depreciation and amortization expenses increased from $37,000 for the 1996 
Interim Period compared to $499,616 for the 1997 Interim Period due to the 
significant increase in property and equipment acquired with the July 31, 1997 
acquisition of the Boots & Coots operating assets.

     The loss of debt extinguishment of $193,333 resulted from the early 
conversion to common stock of $2,900,000 in face amount of the Company's 12% 
Senior Subordinated Notes during the 1997 Interim Period.

     The increase in other expenses from $1,104 during the 1996 Interim Period 
to  $91,973 during the 1997 Interim Period is principally due to interest 
expense on the Company's 12% Senior Subordinated Notes.

     Income taxes of $12,662 during the 1996 Interim Period and $41,370 during 
the 1997 Interim Period results from foreign taxes incurred on Well Control 
projects.

     OVERVIEW

     Such financing alternatives include: (1) the sale, currently underway
through private placement on a best-effort basis, of $10,000,000 of 10% Junior
Redeemable Convertible Preferred Stock; (2) consideration for the offering
through private placement on a best-efforts basis of a Convertible Preferred
Stock Offering; (3) discussions with certain commercial banks for a secured debt
facility; and, (4) discussions regarding the possible private placement of
Subordinated Notes. Although these financing efforts are in process and not yet
completed, Management believes these actions, together with cash flows from
operations, will provide adequate funding to the Company. In the event that one
or more of these financing alternatives under consideration are not
accomplished, the Company could be required to restructure current indebtedness,
sell assets to repay indebtedness, curtail expansion plans and fund business
activities from only internally generated funds.

     In the past seven months, the Company has completed the Boots & Coots,
ABASCO, ITS and Code 3 acquisitions. A primary component of the Company's
business strategy is to increase and diversify the size and scope of the
Company's business operations through acquisitions of complementary businesses.
The Company anticipates that acquisitions will continue to play an important
role in its growth for the foreseeable future. There can be no assurance,
however, that the Company will be able to identify and acquire additional
companies.

     LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash expenditures in connection with the acquisitions of
Abasco, ITS and Code 3 required a substantial portion of the Company's cash
reserves.  Further, the terms upon which Abasco, ITS and Code 3 were acquired
allowed the sellers to retain most or all of the working capital of such
companies.  To date, the Company has funded its operations and acquisitions
from: equity capital contributed by its officers, directors and principal
stockholders; proceeds from the sale in July 1997 of $3,000,000 of the Company's
12% Senior Subordinated Notes due December 31, 2000 (the "Subordinated Notes")
(of which $2,900,000 has been converted into 3,866,653 shares of Common Stock);
$6,481,000 in net proceeds from the private placement, in September 1997, of
7,475,000 shares of Common Stock (the "September Private Placement"); $4,500,000
in net proceeds from the private placement, in January 1998, of the Company's
10% Senior Secured Notes due May 2, 1998 (the "Senior Notes"); $2,250,000 in net
proceeds from the private placement, in March 1998, of additional Senior Notes
due June 15, 1998 ("Additional Senior Notes"); and seller financing in the
aggregate principal amount of $5,760,977, of which approximately $1,500,000
remains outstanding as of the date hereof.

     Accordingly, the Company currently needs additional working capital to fund
its existing operations and to repay indebtedness in the aggregate principal
amount of $8,750,000 which comes due between March 31 and June 15, 1998.  The
Company is exploring various financing alternatives to enable it to retire all
of the outstanding Senior Notes, Additional Senior Notes, seller notes and to
finance future acquisitions by the Company.  There can be no assurance, however,
that the Company will be successful in obtaining financing through alternative
means on acceptable terms.  If the Company is unable to obtain additional
financing on or prior to the May 2, 1998, maturity date of the Senior Notes, it
may be forced to restructure its current indebtedness, sell assets to repay the
indebtedness, curtail its plans for expansion and finance its business
activities with only such internally generated funds as may then be available.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Boots & Coots
International Well Control, Inc. and subsidiaries as of June 30, 1997 and
December 31, 1997, and the results of their operations and their cash flows for
the year ended June 30, 1997 and for the six-month period ended December 31,
1997, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 A.  ORGANIZATION:

   Boots & Coots International Well Control, Inc. (the "Company"), formerly
   known as Havenwood Ventures, Inc. ("Havenwood"), was incorporated in Delaware
   in April 1988. Havenwood was originally formed to serve as a blind pool
   investment fund, and in July 1988 Havenwood raised $499,500 in an initial
   public offering of its Common Stock. After completing its initial public
   offering, Havenwood expended its available resources in the development of a
   business enterprise which it ultimately divested, thereafter remaining
   inactive, with no material assets or liabilities, until it entered into a
   business combination with IWC Services Inc. on July 29, 1997. 

   The Company acquired IWC Services, Inc. ("IWC Services") on July 29, 1997, in
   a "reverse triangular merger" in which it issued shares of Common Stock to
   the stockholders of IWC Services in exchange for all of the issued and
   outstanding common stock of IWC Services and issued options and warrants to
   purchase Common Stock of the Company in exchange for all of the options and
   warrants to purchase common stock of IWC Services then outstanding. As a
   result of the merger, IWC Services became a wholly-owned subsidiary of the
   Company, the stockholders of IWC Services became the beneficial holders of
   approximately 93% of the post-merger issued and outstanding shares of Common
   Stock and the board of directors and management of IWC Services took over the
   management of the Company.

   IWC Services, incorporated in Texas on June 27, 1995, was formed with the
   issuance of 100,000 shares of no par common stock (increased to 5,000,000
   pursuant to a 50-to-one stock split discussed in Note G) in exchange for cash
   of $549,000, property and equipment valued at $108,925 assigned by Buckingham
   Capital Corporation, and services performed by certain other shareholders.
   IWC Services had no operations prior to its acquisition of Hell Fighters,
   Inc. (Hell Fighters). The shareholders of Hell Fighters, a Texas corporation,
   incorporated on May 4, 1995, contributed to IWC Services all of their
   outstanding common shares of Hell Fighters, which then became a wholly-owned
   subsidiary of IWC Services.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 A.  ORGANIZATION: (continued)

   Under the plan of merger between Havenwood and IWC Services, (i) the
   outstanding voting securities of the Company were reverse split in the ratio
   of one post-split share for every 135 pre-split shares held by a shareholder,
   provided, however, that no single shareholder's share ownership was reduced
   to fewer than 100 post-split shares; (ii) certain principal shareholders of
   the Company surrendered a total of 740,740 post-split shares to the Company
   for cancellation, leaving a total of 1,173,074 shares of common stock issued
   and outstanding on the closing date; (iii) each issued and outstanding share
   of common stock of IWC Services was converted into 2.30 post-merger shares of
   the Company's common stock, amounting to approximately 15,502,000 post-merger
   shares in the aggregate (all share amounts herein have been adjusted to
   reflect this 2.30 for 1 split; (iv) outstanding options and warrant to
   purchase shares of the authorized and unissued common stock of IWC Services
   were converted into substantially similar options and warrants to purchase
   shares of the Company's authorized and unissued common stock, and (v) IWC
   Services became a wholly-owned subsidiary of the Company with the former IWC
   Services shareholders, as a group, acquiring shares representing
   approximately 92% of the resulting capitalization of the Company. Following
   the completion of the transactions, there were approximately 16,675,168
   shares of the Company's common stock issued and outstanding, on a fully
   diluted basis. Immediately after the merger, all the officers and directors
   of the Company resigned and were replaced by representatives of IWC. The
   business combination was accounted for as a merger. No goodwill arose from
   this transaction. As IWC Services obtained a controlling interest in the
   Company, the transaction was accounted for as a reverse merger. Therefore,
   for financial statement purposes, IWC Services was considered the acquiror.
   The consolidated financial statements reflect the historical operations and
   cost basis of IWC Services since its inception.

   On July 31, 1997, IWC acquired all of the operating assets, including stock
   of its foreign services subsidiaries, of Boots & Coots, L.P. ("Boots &
   Coots"), an oil and gas well control firefighting, snubbing and industrial
   and marine firefighting company. The consideration paid consisted of (I)
   $369,432 cash payable to Boots & Coots, (ii) $680,568 placed in escrow to pay
   certain debts of Boots & Coots, (iii) the issuance of secured promissory
   notes of the Company in the aggregate principal amount of $4,760,977 and (iv)
   259,901 shares of Common Stock of the Company. The promissory notes are
   secured by the acquired assets of Boots & Coots, and have been paid, with the
   exception of approximately $1,544,000 outstanding at December 31, 1997
   pending final determination of foreign tax obligations which is anticipated
   to be resolved during the quarter end June 30, 1998. This transaction was
   accounted for as a purchase and the acquired assets of Boots & Coots were
   revalued at fair market value as of July 31, 1997 resulting in goodwill of
   $50,000 which will be amortized over 15 years.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 A.  ORGANIZATION: (continued)

   After completion of the merger and the Boots & Coots acquisition, the name of
   Havenwood was changed to Boots & Coots International Well Control, Inc.

   On September 25, 1997, the Company formed a wholly-owned subsidiary company,
   ABASCO, Inc. ("ABASCO") to purchase the assets of ITS Environmental, a
   manufacturer and distributor of rapid response oil and chemical spill
   containment and reclamation equipment and products since 1975. The Company
   paid $1,590,000 cash and issued 300,000 shares of common stock to acquire the
   manufacturing equipment, inventory and customer lists. This transaction was
   accounted for as a purchase and the acquired assets of ABASCO were revalued
   at fair market value effective as of September 12, 1997 resulting in goodwill
   of approximately $749,000 which will be amortized over 25 years.

   The operations of the two acquired entities are included in the Company's
   consolidated operations from the respective acquisition dates. The Company's
   revenues, net loss applicable to common shareholders, and net loss per share
   on an unaudited pro forma basis, assuming that Boots & Coots and ABASCO
   acquisitions occurred on July 1, 1996 would be as follows:

     and natural gas well control segment of the oil and gas services industry,
     providing services on a global basis in oil and gas well blowout control
     and/or firefighting, specialized industrial firefighting and well control
     equipment rental and sales, consulting engineering services, drilling rig
     and production facilities inspection, safety training courses and blowout
     contingency planning.

 B.  SIGNIFICANT ACCOUNTING POLICIES:

     the financial transactions and accounts of the Company and its
     subsidiaries. All significant intercompany accounts and transactions are
     eliminated in consolidation.

 B.  SIGNIFICANT ACCOUNTING POLICIES: (continued)

   Revenue Recognition - Revenue is recognized on the Company's service
   contracts either as earned on the basis of day work completed or, for
   turnkey contracts, on the percentage-of-completion method based upon costs
   incurred to date and estimated total contract costs. Revenue and cost from
   equipment sales is recognized upon contract completion.

   Inventories - Inventories consist primarily of equipment, parts and supplies
   in work-in-progress. Inventories are valued at the lower of cost or market
   using the average cost method.

   Property and Equipment - Property and equipment is stated at cost.
   Depreciation is provided principally using the straight-line method over the
   estimated useful lives of the respective assets as follows: buildings and
   improvements (15 years), well control and fire -fighting equipment (8 years),
   shop and other equipment (8 years), vehicles (5 years) and office equipment
   and furnishings (5 years). Office leasehold improvements are amortized over
   the remaining primary lease terms.

   Goodwill - The Corporation amortizes costs in excess of fair value of net
   assets of businesses acquired using the straight-line method over periods
   ranging from 15 to 25 years. Recoverability is reviewed annually or sooner if
   events or changes in circumstances indicate that the carrying amount may
   exceed fair value. Recoverability is then determined by comparing the
   undiscounted net cash flows of the assets to which the goodwill applies to
   the net book value including goodwill of those assets. Goodwill shown in the
   consolidated financial statements relates to the Company's acquisitions of
   IWC, Boots & Coots LP, and ABASCO, and Hell Fighters.

   Amortization expense was 13,063 in year ended June 30, 1997 and $20,179
   six month for the period ended December 31, 1997. 

   Foreign Currency Translation - The functional currency of the Company's
   foreign operations is the U.S. dollar. All customer invoices and vendor
   payments are denominated in U.S. currency. Revenues and expenses from foreign
   operations are remeasured into U.S. dollars on the respective transaction
   dates and foreign currency transaction gains or losses are included in the
   Consolidated Statements of Operations.

   Income Taxes - The Company accounts for income taxes pursuant to the
   liability method, which requires recognition of deferred income tax
   liabilities and assets for the expected future tax consequences of events
   that have been recognized in the Company's financial statements or tax
   returns. Under this method, deferred income tax liabilities and assets are
   determined based on the temporary differences between the financial statement
   carrying amounts and the tax bases of existing assets and liabilities and
   available tax carryforwards.

 B.  SIGNIFICANT ACCOUNTING POLICIES: (continued)

     Earnings Per Share - Basic and diluted earnings (loss) per share was
     computed by dividing net income (loss) by the weighted average common
     shares outstanding during the year ended June 30, 1997 and the six-month
     period ended December 31, 1997. Options to purchase shares of common stock
     were outstanding during the year ended June 30, 1997 and six-month period
     ended December 31, 1997 but were not included in the computation of diluted
     earnings (loss) per share, either because the option price was greater than
     the average market price of the common stock or were anti-dilutive.

     Recent Accounting Pronouncements  - The Financial Accounting Standards
     Board (FASB) issued SFAS No. 121, Accounting for the Impairment of Long-
     Lived Assets and for Long-Lived Assets to be Disposed of, which is
     effective for fiscal years beginning after December 15, 1995. This
     pronouncement specifies certain events and circumstances which indicate the
     cost of an asset or assets may be impaired, the method by which the
     evaluation should be performed, and the method by which writedowns, if any,
     of the asset or assets are to be determined and recognized. The adoption of
     this pronouncement did not have a material impact on the Company's
     financial condition or operating results upon implementation.

     The FASB issued SFAS No. 123, Accounting for Stock Based Compensation,
     which is effective for fiscal years beginning after December 15, 1995. This
     pronouncement allows companies to choose to adopt the statement's new rules
     for accounting for employee stock-based compensation plans. For those
     companies who choose not to adopt the new rules, the statement requires
     disclosures as to what earnings would have been if the new rules had been
     adopted. Management adopted the disclosure requirements of this statement
     in the fiscal year ended June 30, 1997; see Note D - Capital Stock for
     further discussion.

     The FASB issued SFAS No. 128, Earnings Per Share, effective for financial
     statements issued after December 31, 1997, including interim periods, that
     establishes standards for computing and presenting earnings per share. The
     new statement requires retroactive restatement of all prior-period per
     share data presented. The Company adopted the disclosure requirements of
     this statement and has restated, its 1997 amounts to reflect the adoption
     retroactively.

 B.  SIGNIFICANT ACCOUNTING POLICIES: (continued)

     The FASB issued SFAS No. 130, Reporting Comprehensive Income, and SFAS No.
     131, Disclosures About Segments of an Enterprise and Related Information.
     SFAS No. 130 establishes standards for reporting and display of
     comprehensive income, its components and accumulated balances.
     Comprehensive income is defined to include all changes in equity except
     those resulting from investments by owners and distributions to owners.
     Among other disclosures, SFAS No. 130 requires that all items that are
     required to be recognized under current accounting standards as components
     of comprehensive income be reported in a financial statement that displays
     these items with the same prominence as other financial statements. SFAS
     No. 131 supercedes SFAS No. 14, Financial Reporting for Segments of a
     Business Enterprise. SFAS No. 131 establishes standards on the way that
     public companies report financial information about operating segments in
     annual financial statements and requires reporting of selected information
     about operating segments in interim financial statements issued to the
     public. It also establishes standards for disclosures regarding products
     and services, geographic areas and major customers. SFAS No. 131 defines
     operating segments as components of a company about which separate
     financial information is available that is evaluated regularly by the
     Company management in deciding how to allocate resources and in assessing
     performance.

     SFAS Nos. 130 and 131 are effective for financial statements presented for
     periods beginning after December 15, 1997 and require comparative
     information for earlier years to be restated. Because of the recent
     issuance of these standards, management has been unable to fully evaluate
     the impact, if any, the standards may have on the future financial
     statement disclosures. Results of operations and financial position,
     however, will be unaffected by implementation of these standards.

     Use of Estimates - The preparation of the Company's consolidated financial
     statements in conformity with generally accepted accounting principles
     requires the Company's management to make estimates and assumptions that
     affect the amounts reported in these financial statements and accompanying
     notes. Actual results could differ from these estimates.

     Cash Flow Information - The Company considers all unrestricted, highly
     liquid investments with a maturity of three months or less at the time of
     purchase to be cash equivalents.

     Change in Fiscal Year - Effective December 8, 1997, the Company changed its
     fiscal year from June 30 to December 31. The consolidated financial
     statements include presentation of the transition period beginning on July
     1, 1997 and ending December 31, 1997.

     June 30, 1997 and the six-month period ended December 31, 1997,
     respectively, because of net operating loss carryforwards generated in
     those years. There were no other significant temporary differences as of
     June 30, 1997 and December 31, 1997.

     As of December 31, 1997, the Company has net operating loss carryforwards

F.   NOTES PAYABLE: (continued)

     In January 1997, the Company commenced an offering for up to $5,000,000 of
     debt financing on a "best-efforts" basis through a Private Placement
     Memorandum providing for the issuance of a minimum of 500 and a maximum of
     5,000 Investment Units at a price of $1,000 per Unit with a minimum
     investment of 25 Units. Each Unit consisted of a 12% Senior Subordinated
     Note (the "Notes") of the Company in the principal amount of $1,000 with a
     warrant to purchase under certain circumstances shares of the Company's
     common stock at a discounted price. Management estimated the fair value of
     the proceeds applicable to the warrants issued through June 30, 1997 to be
     $155,000 and during July 1997 to be $145,000, which amounts have been
     reflected as a discount on the Notes and an increase to additional paid-in
     capital. Interest on the Notes at the rate of 12% per annum (13.3%
     effective interest rate based on reduced note balances) is payable semi-
     annually commencing July 1, 1997 with maturity date for the Notes on
     December 31, 2000, subject to extension for up to two periods of six months
     each with an increase in the interest rate to 14%. Net proceeds, after
     sales commissions and offering expenses, (deferred and amortized over term
     of notes) from this financing were utilized for working capital and
     business expansion purposes. Through June 30, 1997 subscriptions for
     $1,555,000 were received and funded. Subsequent to June 30, 1997 the
     Company received additional subscription agreements of $1,445,000 though
     termination of the offering in July 1997.

     Effective September 12, 1997, holders of the Company's 12% Senior
     Subordinated Notes were offered the election to exercise the warrants into
     common stock of the Company at an exchange rate of $.75 per share 
     with payment accomplished through surrender and retirement of their notes.
     An aggregate face amount of $2,900,000 of Notes were converted into an
     aggregate of 3,866,653 shares of common stock with $193,000 recognized as a
     charge to operations for early extinguishment of indebtedness. The carrying
     amount, net of costs associated with debt offering, was transferred to
     equity at time of conversion .

     5,000,000 shares of $0.00001 par value preferred stock, which may be issued
     at the discretion of the Board of Directors. At June 30, 1997 and December
     31, 1997, a total of 14,187,368 shares and 29,998,662 shares, respectively,
     of common stock were issued and outstanding. As discussed in Note A, on
     July 29, 1997 the Company completed a merger with Havenwood Ventures, Inc.
     and the par value of the common stock became $.00001 per share. All
     references herein have been restated to reflect the amended amounts.

     On September 18, 1997, Boots & Coots/IWC closed a private placement
     offering for the sale of 7,475,000 shares of common stock at $1 per share
     for a total of $7,475,000. Proceeds to the Company after placement agents'
     fees and expenses of the offering were approximately $6,323,000 and were
     used for payment on the Boots & Coots, L.P. acquisition notes and for
     working capital. Additionally, the placement agents were awarded 748,000
     warrants at an exercise price of $1.20, which are exercisable for a period
     of four years from grant date.

     In November 1996, the Board of Directors approved the 1996 Incentive Stock
     Plan which allowed the Board of Directors to grant up to 1,500,000
     incentive stock options to eligible employees. These options are
     exercisable by the holders thereof for a period of 10 years from the date
     of grant.

     In November 1997, the Board of Directors approved the 1997 Incentive Stock
     Plan, which will allow the Company to grant an additional 1,475,000
     incentive stock options to eligible employees. The terms of the 1997 plan
     are substantially the same as the 1996 plan discussed above.

     Also in November 1997, the Board of Directors adopted the Outside
     Directors' Option Plan (the "Director's Plan"). The Directors' Plan
     provides for the issuance an option to purchase 15,000 shares per year to
     each member of the Board of Directors who is not an employee of the
     Company. Options may be exercised over a five-year period with the initial
     right to exercise, starting one year from the date of the grant, provided
     the director has not resigned or been removed for cause by the Board of
     Directors prior thereto. After one year from the date of the grant, options
     outstandig under the Director' Plan may be exercised regardless of whether
     the individual continues to serve as a director. Options granted under the
     Directors' Plan are not transferable except by will or by operation of law.
     45,000 options have been granted under the Directors Plan as of December
     31, 1997.

     The Board of Directors also approved an Executive Compensation Plan, which
     will allow the Company to grant additional options covering 1,475,000
     shares of the Company's common stock. The terms of this plan are
     substantially the same as the two incentive plans.

     Activity in these option plans for the year ended June 30, 1997 and 
     December 31, 1997 was as follows:

                                                            Weighted

     As of December 31, 1997, 349,000 ($.43) options are currently exercisable
     and the remaining options vest over a period of five years from date of
     grant.

     In December 1996 and April 1997, the Company issued a total of 1,265,000
     contractual stock options to five persons, including 460,000 options issued
     to certain officers and directors and 350,000 options issued to two
     attorneys. These contractual stock options have a two-year term beginning
     on the original date of grant, are fully vested and are immediately
     exercisable by the holders thereof at a price of $0.43 per share. During
     the six-months ended December 31, 1997, the Company allowed the exercise of
     these options through the redemption of common shares owned by the option
     holders. These shares had been owned for a period adequate to place the
     option holders at risk for market fluctutation; therefore, no compensation
     expense has been recorded by the Company for the shares issued pursuant to
     this option exercise.

G.   SHAREHOLDERS' EQUITY: (continued)

     In December 1997, the Company granted 50,000 options to a consultant at an
     exercise price of $3.66 per share. These options are excercisable upon
     grant and remain exercisable for a period of five years from the grant
     date.

     In September 1997, the Company granted 80,000 options to two consultants at
     an exercise price of $2 per share. These options are exercisable upon grant
     and remain excercisable for a period of four years from the grant date.

     The Company applies APB Opinion 25, Accounting for Stock Issued to
     Employees, and related interpretations in accounting for its plans.
     Accordingly, no compensation cost has been recognized for its stock option
     plans. Had compensation expense for the Company's stock-based compensation
     plans been determined based on the fair value at the grant dates for awards
     under those plans, consistent with the method of SFAS No. 123, the
     Company's reported net loss and net loss per common share would have
     changed to the pro forma amounts indicated below:

 
                                                                  Six-Month

     The fair value of each option grant was estimated on the date of grant
     using Black-Scholes option pricing model with the following assumptions:
     risk-free rate of 6%, volatility of 97%, no assumed dividend yield and
     expected lives of one to three years.

H.   RELATED PARTY TRANSACTIONS:

     The Company shares certain administrative facilities and services including
     corporate office space, administrative personnel and office support
     equipment with Buckingham Capital Corporation, an affiliate of the
     Company's controlling shareholder. For the year ended June 30, 1997 and 
     six-month period ended December 31, 1997, the Company paid approximately 
     $236,000 and $186,000, respectively, to Buckingham Capital Corporation for
     such services. Management believes such charges are comparable to what
     would have been paid to outside parties for such facilities and services.

     During the year ended June 30, 1997 and the six-month period ended December
     31, 1997, the Company incurred $155,500 and $144,500, respectively, in
     financial consulting fees for services rendered by Buckingham Capital
     Corporation in connection with the Company's private offering of $3,000,000
     principal amount of 12% Senior Subordinated Notes. Such amounts were
     included with deferred financing costs in the consolidated balance sheet
     and amortized over the term of the Notes, $2,900,000 of which were
     converted to equity in September 1997 (see Note F).

J.   REVENUES FROM MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK: (continued)

The Company's revenues are generated geographically as follows:

                                                          Six-Month

               Domestic customers           71%              61%
               Foreign customers            29%              39%

     Four of the Company's customers (each in excess of 10%) collectively
     accounted for 86% of outstanding accounts receivable at June 30, 1997.
     Two of the Company's customers collectively accounted for 27% of 
     outstanding accounts receivable at December 31, 1997. The Company believes
     that future accounts receivable with these companies will continue to be
     collected under normal credit terms based on previous experience. The
     Company performs ongoing evaluations of its customers and generally does
     not require collateral. The Company assesses its credit risk and provides
     an allowance for doubtful accounts for any accounts which it deems doubtful
     of collection.

     The Company maintains deposits in banks which may exceed the amount of
     federal deposit insurance available. Management believes that any possible
     deposit loss is minimal.

K.   EVENTS SUBSEQUENT TO DECEMBER 31, 1997:

     On January 2, 1998, the Company completed the funding of the acquisition,
     effective as of December 31, 1997, of all of the capital stock of ITS
     Supply Corporation ("ITS") for aggregate consideration of $6,000,000.
     Financing for the acquisition of ITS was provided from working capital
     ($500,000); proceeds from the issuance of 10% Senior Secured Notes due May
     21, 1998 ($4,500,000); and short-term bridge financing from the seller
     ($1,000,000).

     In connection with the sale through private placement of the 10% Senior
     Secured Notes on January 2, 1998, the Company entered into a financial
     advisory arrangement pursuant to which the note holders are to provide a
     certain level of financial, merger and acquisition advisory services over a
     three-year period in consideration of an advance cash consulting fee of
     $500,000, all of which was added to the principal balance of the Senior
     Secured Notes. The commitment for the Senior Secured Notes by the note
     holders also required the payment by the Company of a $50,000 commitment
     fee. The note holders were also issued warrants exercisable over a six year
     term to purchase an aggregate of 2,000,000 shares of the Company's Common
     Stock at a price of $2.62 per share.

K.   EVENTS SUBSEQUENT TO DECEMBER 31, 1997: (continued)

     The ITS seller obligation of $1,000,000 bears interest at the rate of 10%
     per annum is payable on March 31, 1998.

     For its most recent fiscal year ended March 31, 1997, ITS contributed
     revenues of approximately $41,000,000 and pre-tax operating income of
     approximately $1,000,000 to the consolidated operating results of its
     former parent company (unaudited). The above pre-tax operating income is
     prior to allocations of a portion of the former parent company's corporate
     overhead expenses to ITS. Such corporate overhead expense allocations are
     not considered to be indicative of incremental costs, if any, to be
     incurred by the Company as a result of its ownership of ITS.

     On February 20, 1998, the Company completed the acquisition of all of the
     stock of Code 3, Inc. ("Code 3"). Consideration for the acquisition of Code
     3, with an effective date for audited purchase price adjustments of
     December 31, 1997, was $570,568 cash; the repayment of corporate secured
     debt and interest thereon of approximately $1,250,000; and the issuance of
     488,136 shares of the Company's Common Stock, of which 158,646 shares were
     delivered into escrow to secure the indemnification obligations of the
     stockholders of Code 3. Code 3 reported unaudited revenues of approximately
     $4,800,000 and pre-tax income of approximately $296,000 for its fiscal year
     ended December 31, 1997.

     On March 5, 1998, the Company sold through private placement to the
     noteholders an additional $2,250,000 of 10% Senior Secured Notes due June
     15, 1998. In addition, these note holders were issued warrants, exercisable
     over a six year term, to purchase an additional 500,000 shares of the
     Company's common stock at a price of $4.50 per share.

     Management has undertaken steps to finance its working capital and 
     expansion plan. Such financing alternatives include: (1) the sale,
     currently underway through private placement on a best-effort basis, of
     $10,000,000 of 10% Junior Redeemable Convertible Preferred Stock; (2)
     consideration for the offering through private placement on a best-efforts
     basis of a Convertible Preferred Stock Offering; (3) discussions with
     certain commercial banks for a secured debt facility; and, (4) discussions
     regarding the possible private placement of Subordinated Notes. Although
     these financing efforts are in process and not yet completed, Management
     believes these actions, together with cash flows from operations, will
     provide adequate funding to the Company.

     4.1  Principal Payments.  All of the principal of the Notes remaining
outstanding on May 2, 1998, together with interest accrued thereon, shall become
due and payable on May 2, 1998.

     4.2  Interest Payments.  The Notes will bear interest at the rate of 10.0%
per annum, such interest to be payable monthly in arrears commencing February 1,
1998, and on the first day of each month thereafter until May 2, 1998, when all
principal, together with accrued and unpaid interest shall be due and payable.
If an Event of Default shall have occurred, and for so long as such Event of
Default continues, or if any payment of principal, interest or fees is not paid
when due, interest shall accrue upon the principal of the Notes, together with
any accrued and unpaid interest and fees, at the Highest Lawful Rate.  It is the
intention of the holder of the Notes to conform strictly to usury laws
applicable to them.  Accordingly, if the transactions contemplated hereby or the
Notes would be usurious as to any of the holders of the Notes under laws
applicable to it (including the laws of the United States of America and the
State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such holder notwithstanding the other provisions of this
Agreement, the Notes or any other Document), then, in that event,
notwithstanding anything to the contrary in this Agreement, the Notes or any
other Document, it is agreed as follows:  (i) the aggregate of all consideration
which constitutes interest under laws applicable to such holder that is
contracted for, taken, reserved, charged or received by such holder under this
Agreement, the Notes or any other Document or otherwise shall under no
circumstances exceed the Highest Lawful Rate, and any excess shall be credited
by such holder on the principal amount of the Notes (or, if the principal amount
of such Notes shall have been paid in full, refunded by such holder to the
Company); (ii) in the event that the maturity of the Notes is accelerated by
reason of an election of the holder or holders thereof resulting 

                                       11
<PAGE>
 
from any Event of Default hereunder or otherwise, or in the event of any
required or permitted prepayment, then such consideration that constitutes
interest under laws applicable to such holder may never include more than the
Highest Lawful Rate, and excess interest, if any, provided for in this

canceled by such holder as of the date of such acceleration or prepayment and,
if theretofore paid, shall be credited by such holder on the principal amount of

the interest provided under the Notes or the Agreement, together with any other

at the Highest Lawful Rate, the amount of interest and any such fees to accrue
to such holder hereunder and thereunder shall be limited to the amount which
would have accrued at the Highest Lawful Rate, but any subsequent reductions
shall not reduce the interest to accrue to such holder hereunder and thereunder

other manner as may be reasonably directed or to such other address in the

to, any Note shall fall on a day other than a Business Day, then such payment
shall be made on the first Business Day following the day on which such payment
shall have so fallen due, provided that if all or any portion of such payment
shall consist of a payment of interest, for purposes of calculating such
interest, such payment shall be deemed to have been originally due on such first
following Business Day, such interest shall accrue and be payable to (but not
including) the actual date of payment and the amount of the next succeeding
interest payment shall be adjusted accordingly.

          (c) Payments, When Received.  Any payment to be made to the holders of

losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all reasonable attorneys' fees and other
reasonable expenses of investigating, defending against claims, litigation or

which any of them may pay or incur arising out of or relating to (i) any action,
suit or proceeding by any third party or governmental authority against such
Indemnified Party and relating to any Document or the application or proposed
application by the Company of the proceeds of any Note, REGARDLESS OF WHETHER

RESPECTIVE SHAREHOLDERS, DIRECTORS, OFFICERS, PARTNERS, EMPLOYEES OR ATTORNEYS,
(ii) any investigation of any third party or any governmental authority
involving any Indemnified Party and related to any use made or proposed to be

authority, litigation or proceeding involving any Indemnified Party by virtue of
the Documents and related to any environmental cleanup, audit, compliance or
other matter relating to any Environmental Law or the presence of any Hazardous
Material (including, without limitation, any losses, liabilities, damages,
injuries, costs, expenses or claims asserted or arising under any

terms and conditions therein set forth, the Debtor has issued its 10.0% Senior

rearranged, and/or restated from time to time, together with any notes given by
the Debtor in extension, replacement, rearrangement, modification and/or
substitution thereof or therefor, collectively called the "Notes" and any

     B.  Under the terms of the Note Purchase Agreements, the Debtor is required
by each of  Geneva and Main Street to provide certain security in respect of the
liabilities of the Debtor under the Note Purchase Agreements, and each of Geneva
and Main Street requires that this Agreement be entered into by the Debtor as a

     additions, accessories and improvements to any equipment and all
     substitutions therefor and all accessories, parts and equipment which may
     be attached to or which are necessary for the operation and use of any
     equipment, personal property or fixtures, together with all accessions
     thereto;

          (b) All accounts (as defined in the UCC) and accounts receivable now
     owned or hereafter acquired by the Debtor;

          (c) All rights of the Debtor under or arising out of present or future

          (d) All rights of the Debtor in, to and under all patents, trademarks,

     of convenience or necessity franchises, immunities, easements, consents,
     grants, ordinances or other rights granted by any governmental authority;

          (f) All rights of the Debtor in and to all books, records, writings,

Securities Agreement and Financing Statement
Page 2
<PAGE>
 
     foregoing;

          (g) All rights of the Debtor in, to or under (i) all sales orders,
     sales contracts, purchase orders, purchase contracts, operating agreements,
     management agreements, service agreements, development agreements,
     consulting agreements and leases and (ii) all other contract rights,
     general intangibles (as defined in the UCC) and, to the extent they can
     lawfully be conveyed or assigned, under express or implied warranties from
     providers of goods or services;

          (h) All rights of the Debtor in, to and under all products,
     accessions, rents, issues, profits, returns, income and proceeds of any and
     all Collateral and, to the extent not otherwise included, all rights of the
     Debtor in, to and under all payments under insurance or any indemnity,
     warranty or guaranty payable by reason of any loss or damage to any
     Collateral or otherwise with respect to any of the Collateral; and

          (i) All rights of the Debtor in, to and under all moneys and
     securities deposited with the Secured Party pursuant to any term of this
     Agreement or any other Document to be held by the Secured Party hereunder
     or thereunder (collectively "Cash Collateral").

All of the foregoing property, whether now owned or hereafter acquired, other
than the Excluded Items, is hereinafter collectively referred to as the
"Collateral"; Collateral described in clauses (g) and (h) may be referred to
herein as "Collateral Proceeds").  To have and to hold all and singular the
Collateral by the Secured Party, its successors and assigns, in trust for the
benefit and security of the Secured Party and for the uses and purposes, and
subject to the terms and provisions, set forth in this Agreement and in the Note
Purchase Agreements.  Any term of this Agreement to the contrary
notwithstanding, the Collateral does not include any of the Excluded Items.  The
term "Excluded Items" means and includes all properties or assets described
above, whether now owned or hereafter acquired by the Debtor, which by their
terms or by reason of applicable law would become void or voidable if a security
interest therein were granted hereunder by the Debtor or which cannot be
granted, conveyed, mortgaged, transferred or assigned by this Agreement or in
which a security interest cannot effectively be granted hereunder.

     3.   Rights of Debtor; Debtor Remains Liable.

          (a) Any term of this Agreement to the contrary notwithstanding, until
     written notice shall be given to the Debtor in accordance with Section 10
     that the Secured Party is exercising its rights under Section 10, the
     Debtor shall have the right, subject to the prohibitions contained in the
     Note Purchase Agreements to possess, retain, enjoy and use the Collateral,
     to give consents, waivers or notifications with respect to the Collateral,
     to exercise its rights, powers and privileges under the Collateral, to
     agree to any modification of any of the terms of the Collateral, to dispose
     of any of the Collateral (it being agreed that the Lien of this Agreement
     shall attach to the proceeds thereof), and 

Securities Agreement and Financing Statement
Page 3
<PAGE>
 
     otherwise to act with respect to the Collateral in the ordinary course of
     business, in each case other than with respect to any Cash Collateral held
     by the Secured Party. The Secured Party shall from time to time execute
     such instruments and take such other action, in each instance, at the
     Debtor's sole expense, as may reasonably be requested of it to give effect
     to, or to confirm any action taken by the Debtor in accordance with this
     Section 3(a).

          (b) Any term of this Agreement to the contrary notwithstanding, until
     written notice shall be given to the Debtor in accordance with Section 10
     that the Secured Party is exercising its rights under Section 10, the
     Debtor shall be entitled, from time to time, except as may otherwise be
     provided in the Note Purchase Agreements, to collect and receive for its
     own use all Collateral Proceeds.  Any Collateral Proceeds collected or
     received by or paid over to the Debtor pursuant to this Section 3(b) may be
     used, distributed or otherwise disposed of by the Debtor as it determines
     except as may otherwise be provided in the Note Purchase Agreements.

          (c) Anything herein to the contrary notwithstanding, (i) the Debtor
     shall remain liable under the contracts and agreements included in the
     Collateral to the extent set forth therein (and subject to any defenses
     thereto), to perform all of its duties and obligations thereunder to the
     same extent as if this Agreement had not been executed, (ii) the exercise
     by the Secured Party of any of the rights hereunder shall not release any
     Debtor from any of its duties or obligations under the contracts and
     agreements included in the Collateral, and (iii) the Secured Party shall
     not have any obligation or liability under the contracts and agreements
     included in the Collateral solely by reason of this Agreement, nor shall
     the Secured Party be obligated to perform any of the obligations or duties
     of the Debtor thereunder or to take any action to collect or enforce any
     claim for payment assigned hereunder, in each case, solely by reason of
     this Agreement.

     4.   Representations and Warranties.  The Debtor represents and warrants as
follows:

          (a) The Debtor owns the Collateral presently owned by it free and
     clear of any Lien, except for Permitted Liens.  No effective financing
     statement, mortgage, or other instrument similar in effect covering all or
     any part of the Collateral is on file in any recording office, except for
     (i) protective filings under true leases, (ii) filings filed in favor of
     the Secured Party for the benefit of the Secured Party relating to this
     Agreement, and (iii) filings, if any, with respect to Permitted Liens.

          (b) This Agreement has been duly executed and delivered by the Debtor.
     Upon the filing of financing statements in the locations requested by the
     Secured Party, the security interests granted herein shall constitute valid

     Permitted Liens, to the extent such security interests can be perfected by
     such filings pursuant to the UCC.

Securities Agreement and Financing Statement

<PAGE>
 
          (c) As of the date hereof, no consent of, or notice to, any other
     Person and no authorization, approval or other action by, and no notice to
     or filing with, any governmental authority or regulatory body is required
     for the grant by the Debtor of the Liens granted hereby or for the
     execution, delivery or performance of this Agreement by the Debtor, other
     than the filing of financing statements as provided in (b) above and except
     for such other consents, notices or filings that have been obtained or made
     or that as of the date hereof are not required to have been obtained or
     made and may be obtained or made, as the case may be, when necessary.

     5.   Further Assurances.

          (a) The Debtor agrees that from time to time, at the expense of the
     Debtor, that it will promptly execute and deliver all further instruments
     and documents, and take all further action, that the Secured Party may
     reasonably request as being necessary or desirable in order to perfect and
     protect any security interest granted or purported to be granted hereby or
     to enable the Secured Party to exercise and enforce its rights and remedies
     hereunder with respect to any Collateral.  Without limiting the generality
     of the foregoing, the Debtor will execute and file such financing or
     continuation statements, or amendments thereto, and such other instruments
     or notices, as the Secured Party may request as being necessary or
     desirable in order to perfect and preserve the security interests granted
     or purported to be granted hereby.

          (b) The Debtor hereby authorizes the Secured Party to file one or more
     financing or continuation statements, and amendments thereto, relative to
     all or any part of the Collateral without the signature of the Debtor, in
     each case where permitted by law.  A carbon, photographic or other
     reproduction of any financing statement executed by the Debtor covering the
     Collateral or any part thereof shall be sufficient as a financing statement
     where permitted by law.

          (c) The Debtor will furnish to the Secured Party from time to time
     such statements and schedules further identifying and describing the
     Collateral, and such other reports in connection with the Collateral, as
     the Secured Party may reasonably request at reasonable intervals, all in
     reasonable detail.

          (d) The Debtor will promptly notify the Secured Party of any change of
     its name, corporate structure, federal employer identification number or
     the address of its principal place of business or chief executive office
     where its books and records are maintained.

          (e) The Debtor shall keep its principal place of business and chief
     executive office and the office where it keeps its records concerning the
     Collateral, at the address beside its signature hereto or, upon thirty (30)
     days' prior written notice (or such other notice acceptable to the Secured
     Party) to the Secured Party, at such other locations in 


Securities Agreement and Financing Statement
Page 5
<PAGE>
 
     a jurisdiction where all action required by this Section 5 shall have been
     taken with respect to the Collateral. The Debtor will hold and preserve
     such records and will upon reasonable notice permit representatives of the
     Secured Party at any time during normal business hours to inspect and make
     abstracts from such records.

     6.   Insurance.  The Debtor shall, at its own expense, maintain insurance
with respect to the Collateral as required by the Note Purchase Agreements.

     7.   Transfers and Other Liens.  The Debtor shall not (i) Transfer any of
the Collateral except as permitted by the Note Purchase Agreements, or (ii)
create or suffer to exist any Lien upon or with respect to any of the
Collateral, except for Permitted Liens.

     8.   Secured Party's Duties.  The powers conferred on the Secured Party
hereunder are solely to protect its interest in the Collateral and shall not
impose any duty upon it to exercise any such powers.  Except for reasonable care
in the custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, the Secured Party shall have no duty as to
any Collateral or as to the taking of any necessary steps to preserve rights
against other parties or any other rights pertaining to any Collateral.  The
Secured Party shall be deemed to have exercised reasonable care in the custody
and preservation of any Collateral in its possession if such Collateral is
accorded treatment substantially equal to that which the Secured Party accords
its own property, it being understood that the Secured Party shall not have any
responsibility for taking any necessary steps to preserve rights against other
parties or any other rights with respect to any Collateral.

     9.   Events of Default.  The Debtor shall be in default under this
Agreement upon the occurrence of and during the continuation of any of the
events or conditions defined as Events of Default in any of the Note Purchase
Agreements (an "Event of Default").

     10.  Remedies.  If any Event of Default shall have occurred and be
continuing, to the extent not prohibited by applicable law:

          (a) The Secured Party may exercise in respect of the Collateral, in
     addition to other rights and remedies provided for herein or under the Note
     Purchase Agreements, the other Documents or otherwise available to it, all
     the rights and remedies of a secured party on default under the UCC
     (whether or not the UCC applies to the affected Collateral), and the
     Secured Party may also (i) require the Debtor to, and the Debtor hereby
     agrees that it will, at its expense and upon request of the Secured Party,
     forthwith (but in no event sooner than can be effectuated in compliance
     with all applicable laws) assemble all or part of the Collateral as
     directed by the Secured Party and make it available to the Secured Party at
     a place to be designated by the Secured Party which is reasonably
     convenient to both parties, and (ii) without notice except as specified
     below, sell, assign or otherwise convey (as applicable) the Collateral or
     any part thereof in one or more parcels at public or private sale, for cash
     or on credit, and upon such other terms as may be commercially reasonable.
     The Debtor agrees, to the fullest extent that it may

     effectively do so under applicable law, that, to the extent notice of sale
     shall be required by law, at least ten (10) days' prior notice to the
     Debtor of the time and place of any public sale or the time after which any
     private sale is to be made shall constitute reasonable notification thereof
     within the meaning of Section 9.504(c) of the UCC. The Secured Party shall
     not be obligated to make any sale of Collateral regardless of notice of
     sale having been given. The Secured Party may adjourn any public or private
     sale from time to time by announcement at the time and place fixed
     therefor, and such sale may, without further notice, be made at the time
     and place to which it was so adjourned.

          (b) Any proceeds of the Collateral received by the Secured Party may,
     and if direct by the Debtor shall, be applied to the Notes pursuant to the
     terms of the Note Purchase Agreements and the Intercreditor Agreement.

          (c) All rights of marshalling of assets of the Debtor, including any
     such right with respect to the Collateral, are hereby waived by the Debtor,
     to the fullest extent that it may effectively do so under applicable law.

     11.  Attorney-in-Fact.  The Debtor further agrees, at its expense, to do,
make, procure, assign, endorse, and deliver all acts, things, writings
(including, without limitation, any check, endorsement, certificate or any other
instrument required by the Secured Party), and assurances as the Secured Party
may at any time reasonably require to protect, assure, or enforce its interest
and remedies created by this Agreement.  The Debtor further agrees that while
any Event of Default is continuing, the Secured Party may receive any and all
proceeds or income from the Collateral, and the Secured Party may execute,
assign, and endorse appropriate receipts, releases and satisfaction, or
negotiable or non-negotiable instruments, or any other instruments or documents
in the name of and as agent for the Debtor, or in its own name, which the Debtor
has agreed to execute, sign, or endorse herein or any assigned agreements or
contracts, and the Secured Party is hereby constituted and appointed the agent
and attorney-in-fact of the Debtor to do all acts with respect to any of the
Collateral necessary or desirable to accomplish the purposes of this Agreement,
and to execute and endorse all such instruments, in each case while any Event of
Default shall be continuing.  The Debtor agrees that this power of attorney is
coupled with an interest and may not be revoked until this Agreement is no
longer in full force and effect as provided in Section 22.  At such time
thereafter or after such Event of Default shall cease to be continuing, any
amounts then held by Secured Party pursuant to this Section 11 shall be paid
over to the Debtor.

     12.  No Waiver; Cumulative Remedies.  No failure on the part of the Secured
Party to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power, or privilege under this Agreement shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, power,
or privilege under this Agreement preclude any other or further exercise thereof
or the exercise of any other right, power, or privilege.  To the fullest extent
permitted by applicable laws, the rights and remedies provided for in this
Agreement are cumulative and not exclusive of any rights and remedies provided
by law.

capable of delivery) promptly to Secured Party in the exact form received, with
the appropriate endorsement of Pledgor when necessary and/or appropriate undated
stock powers duly executed in blank, to be held by Secured Party, as additional
Collateral for the Obligations, subject to the terms hereof.  Any sums paid upon

continuing or any property shall be distributed while a Default or an Event of
Default shall be continuing upon or with respect to the Collateral pursuant to
any recapitalization or reclassification of the capital of the issuer thereof or
pursuant to any reorganization of the issuer thereof, the property so
distributed shall be delivered to the Secured Party to be held by it, as
additional Collateral for the Obligations, subject to the terms hereof.  All

held by Pledgor in trust as additional security for the Obligations, provided
that except to the extent that such sums of money or property have theretofore
been applied against the Obligations in accordance with the Note Purchase
Agreement, such sums of money or property shall forthwith be delivered to
Pledgor at such time as no Default or Event of Default shall be continuing under
the Note Purchase Agreement.

     3.04.  Further Assurances.  Pledgor has delivered the certificate
representing the stock referred to in Section 1.01 (a) to Secured Party, with an
undated stock power duly executed in blank to be held by Secured Party as
Collateral for the Obligations, subject to the terms hereof.  At any time and
from time to time, upon the request of Secured Party, and at the sole expense of
Pledgor, Pledgor shall promptly execute and deliver all such further instruments
and documents and take such further action as Secured Party may deem reasonably
necessary or desirable to preserve and perfect its security interest in the
Collateral and carry out the provisions and purposes of this Agreement,
including, without limitation, the execution and filing of such financing
statements as Secured Party may require.  A carbon, photographic, or other
reproduction of this Agreement or of any financing statement covering the
Collateral or any part thereof shall be sufficient as a financing statement and
may be filed as a financing statement to the extent provided by applicable law.

     3.05.  Inspection Rights.  Upon reasonable notice from Secured Party,
Pledgor shall permit Secured Party and its representatives to examine, inspect,
and copy Pledgor's books and records concerning ownership of the Collateral at
any reasonable time during normal business hours and as often as Secured Party
may desire.

     3.06.  Notification.  Pledgor shall promptly after either Person has
knowledge thereof, notify Secured Party of (i) any lien, security interest,
encumbrance, or claim made or threatened against the Collateral other than
Permitted Liens, and (ii) the occurrence or existence of any Default or Event of
Default.

     3.07.  Books and Records.  Pledgor shall mark its books and records to
reflect the security interest of Secured Party under this Agreement.

     3.08.  Additional Securities.  Pledgor shall not consent to or approve the
issuance of any additional shares of any class of capital stock of the Company
or any securities convertible into, or exchangeable for, any such shares or any
warrants, options, rights, or other commitments entitling any person or entity
to purchase or otherwise acquire any such shares.

     4.01.  Power of Attorney.  Pledgor hereby irrevocably constitutes and
appoints Secured Party and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead and in the name of Pledgor or in its
own name, from time to time in Secured Party's discretion during the continuance
of an Event of Default and prior to the Collateral Termination Date, to take any
and all action and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement and, without
limiting the generality of the foregoing, hereby gives Secured Party the power
and right on behalf of Pledgor and in its own name to do any of the following
after the occurrence and during the continuance of an Event of Default and to
the extent permitted by applicable laws, without notice to or the consent of
Pledgor:

     (a)  to demand, sue for, collect, or receive in the name of Pledgor or in
          its own name, any money or property at any time payable or receivable
          on account of or in exchange for any of the Collateral and, in
          connection therewith, endorse checks, notes, drafts, acceptances,
          money orders, or any other instruments for the payment of money under
          the Collateral;

     (b)  to pay or discharge taxes, liens, security interests, or other
          encumbrances (other than Permitted Liens) levied or placed on or
          threatened against the Collateral;

     (c)  (i) to direct account debtors and any other parties liable for any
          payment  under any of the Collateral to make payment of any and all
          monies due and to become due thereunder directly to Secured Party or
          as Secured Party shall direct; (ii) to receive payment of and receipt
          for any and all monies, claims, and other amounts due and to become
          due at any time in respect of or arising out of any Collateral; (iii)
          to sign and endorse any drafts, assignments, proxies, stock powers,
          verifications, notices, and other documents relating to the
          Collateral; (iv) to commence and prosecute any suit, actions or
          proceedings at law or in equity in any court of competent jurisdiction
          to collect the Collateral or any part thereof and to enforce any other
          right in respect of any Collateral; (v) to defend any suit, action, or
          proceeding brought against Pledgor with respect to any Collateral;
          (vi) to settle, compromise, or adjust any suit, action, or proceeding
          described in clause (v) above and, in connection therewith, to give
          such discharges or releases as Secured Party may deem appropriate;
          (vii) to exchange any of the Collateral for other property upon any
          merger, consolidation, reorganization, recapitalization, or other
          readjustment of the issuer thereof and, in connection therewith,
          deposit any of the Collateral with any committee, depositary, transfer
          agent, registrar, or other designated agency upon such terms as
          Secured Party may determine; (viii) to add or release any guarantor,
          endorser, surety, or other party to any of the Collateral or the
          Obligations; and (ix) to sell, transfer, pledge, make any agreement
          with respect to or otherwise deal with any of the Collateral as fully
          and completely as though Secured Party were the absolute owner thereof
          for all purposes, and to do, at Secured Party's option and Pledgor's
          expense, at any time, or from time to time, all acts and things which
          Secured Party deems necessary to protect, preserve, or realize upon
          the Collateral and Secured Party's security

          interest.

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  Secured Party shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to Secured Party in this Agreement, and shall not be liable
for any failure to do so or any delay in doing so.  Secured Party shall not be
liable for any act or omission or for any error of judgment or any mistake of
fact or law in its individual capacity or in its capacity as attorney-in-fact
except acts or omissions constituting or resulting from its willful misconduct
or gross negligence.  This power of attorney is conferred on Secured Party
solely to protect, preserve, and realize upon its security interest in the
Collateral.

     4.02.  Voting Rights.  Until written notice shall be given to Pledgor in
accordance with Section 5.02(d) that Secured Party has exercised its rights
under Section 5.02(d) to vote the Collateral (provided, however, if Secured
Party is prevented from providing such notice as a result of Section 362 of the
United States Bankruptcy Code or similar law Pledgor shall be entitled to
exercise such rights so long as no Event of Default shall have occurred and be
continuing), Pledgor shall be entitled to exercise any and all voting and other
rights relating or pertaining to the Collateral or any part thereof (and the
Secured Party shall execute and deliver (or cause to be executed and delivered)
to Pledgor all such proxies and other instruments as Pledgor may reasonably
request for the purpose of enabling Pledgor to exercise the voting and other
rights which it is entitled to exercise pursuant to this sentence).

     4.03.  Dividends.   Until written notice shall be given to Pledgor in
accordance with Section 5.02(d) that Secured Party has exercised its rights
under Section 5.02(d) to vote the Collateral, Pledgor shall be entitled to
receive and collect for its own use all Collateral Proceeds.

     4.04.  Performance by Secured Party of Pledgor's Obligations.  If an Event
of Default has occurred and is continuing or if Pledgor fails to perform or
comply with any of its agreements contained herein and Secured Party itself
shall cause performance of or compliance with such agreement, the reasonable
expenses of Secured Party, together with interest thereon at the rate of
interest provided in the Note Purchase Agreement, shall be payable by Pledgor to
Secured Party on demand and shall constitute Obligations secured by this
Agreement.

     4.05.  Secured Party's Duty of Care.  Other than the exercise of reasonable
care in the physical custody of the Collateral while held by Secured Party
hereunder, Secured Party shall have no responsibility for or obligation or duty
with respect to all or any part of the Collateral or any matter or proceeding
arising out of or relating thereto, including, without limitation, any
obligation or duty to collect any sums due in respect thereof or to protect or
preserve any rights against prior parties or any other rights pertaining
thereto, it being understood and agreed that Pledgor shall be responsible for
preservation of all rights in the Collateral.  Without limiting the generality
of the foregoing, Secured Party shall be conclusively deemed to have exercised
reasonable care in the custody of the Collateral if Secured Party takes such
action, for purposes of preserving rights in the Collateral, as Pledgor may
reasonably request in writing, but no failure or omission or delay by Secured
Party in complying with any such request by Pledgor, 


Stock Pledge Agreement
Page 6
<PAGE>
 
and no refusal by Secured Party to comply with any such request by Pledgor,
shall of itself be deemed to be a failure to exercise reasonable care.

                                   ARTICLE V
                                    Default

     5.01.  Events of Default.  Each of the following shall be deemed an "Event
of Default":

     (a)  The failure of the Collateral pledged to Secured Party hereunder to
          constitute at least one hundred percent (100%) of the issued and
          outstanding stock of the Company;

     (b)  An Event of Default under any Note Purchase Agreement shall have
          occurred;

     (c)  Failure by Pledgor to perform any agreement contained herein and
          continuance of such non-compliance or failure for thirty (30) days
          after notice thereof to Pledgor from Secured Party; or

     (d)  Any representation, statement or warranty of Pledgor contained herein
          shall be untrue in any material respect as of the date made.
 
     5.02.  Rights and Remedies.  Prior to the Collateral Termination Date, upon
the occurrence of an Event of Default and so long as the same shall be
continuing, Secured Party shall have the following rights and remedies to the
extent not prohibited by applicable laws:

     (a)  In addition to all other rights and remedies granted to Secured Party
          in this Agreement and in any other instrument or agreement securing,
          evidencing, or relating to the Obligations, Secured Party shall have
          all of the rights and remedies of a secured party under the Uniform
          Commercial Code as adopted by the State of Texas.  Without limiting
          the generality of the foregoing, Secured Party may (A) without demand
          or notice to Pledgor, collect, receive, or take possession of the
          Collateral or any part thereof, (B) sell or otherwise dispose of the
          Collateral, or any part thereof, in one or more parcels at public or
          private sale or sales, at Secured Party's offices or elsewhere, for
          cash, on credit, or for future delivery without assumption of any
          credit risk, and/or (C) bid and become a purchaser at any such sale
          free of any right or equity of redemption in Pledgor, which right or
          equity is hereby expressly waived and released by Pledgor.  Upon the
          request of Secured Party, Pledgor shall assemble the Collateral and
          make it available to Secured Party at any place designated by Secured
          Party that is reasonably convenient to Pledgor and Secured Party.
          Pledgor agrees that Secured Party shall not be obligated to give more
          than ten (10) days' prior written notice of the time and place of any
          public sale or of the time after which any private sale may take place
          and that such notice shall constitute reasonable notice of such
          matters.  Pledgor shall be liable for all reasonable expenses of
          retaking, holding, preparing for sale, or the like, and all reasonable
          attorneys' fees and other reasonable 

Stock Pledge Agreement
Page 7
<PAGE>
 
          expenses incurred by Secured Party in connection with the collection
          of the Obligations and the enforcement of Secured Party's rights under
          this Agreement, in each case during the continuance of an Event of
          Default, all of which expenses and fees shall constitute additional
          Obligations secured by this Agreement. Secured Party may apply the
          Collateral against the Obligations then due and payable in such order
          and manner as provided in Section 6.15. Pledgor shall remain liable
          for any deficiency if the proceeds of any sale or disposition of the
          Collateral are insufficient to pay the Obligations. Pledgor waives all
          rights of marshalling in respect of the Collateral.

     (b)  Secured Party may cause any or all of the Collateral held by it to be
          transferred into the name of Secured Party or the name or names of
          Secured Party's nominee or nominees (in each case as pledgee
          hereunder).

     (c)  Secured Party shall be entitled to receive all cash dividends payable
          in respect of the Collateral.

     (d)  Secured Party shall have the right, but shall not be obligated to,
          exercise or cause to be exercised all voting rights and corporate
          powers in respect of the Collateral, and Pledgor shall deliver to
          Secured Party, if requested by Secured Party, irrevocable proxies with
          respect to the Collateral in form satisfactory to Secured Party.

Because of applicable securities laws, including without limitation, the
Securities Act of 1933, as amended, the securities laws of Texas and other
applicable state securities laws, there may be legal restrictions or limitations
affecting attempts of Secured Party to dispose of the Collateral in the
enforcement of its rights and remedies hereunder.  Secured Party is hereby
authorized by Pledgor, but not obligated, upon the occurrence and during the
continuance of an Event of Default, to the extent permitted by applicable law,
to sell all or any part of the Collateral at private sale, subject to investment
letters or in any other manner which will not require the Collateral or any part
thereof, to be registered in accordance with the Securities Act of 1933, as
amended, or the rules and regulations promulgated thereunder, or any other
applicable securities law or regulation.  Pledgor specifically agrees that under
these circumstances, such a sale is a commercially reasonable method of
disposition of the Collateral.  Secured Party is also hereby authorized by
Pledgor, but not obligated, to take such actions, give such notices, obtain such
rulings and consents, and do such other things as Secured Party may deem
appropriate in the event of such a sale or disposition of any of the Collateral.
Pledgor acknowledges that Secured Party may, in its reasonable discretion,
approach a restricted number of potential purchasers and that a sale under such
circumstances may yield a lower price for the Collateral or any part or parts
thereof than would otherwise be obtainable if the same were registered and sold
in the open market.  Pledgor agrees that such private sale shall constitute a
commercially reasonable method of disposing of the Collateral in view of the
time, expense, and potential liability to the parties of such transactions of
registration of the Collateral in accordance with applicable securities laws.

                                   ARTICLE VI
                                 Miscellaneous

     6.01.  No Waiver; Cumulative Remedies.  No failure on the part of Secured
Party to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power, or privilege under this Agreement shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, power,
or privilege under this Agreement preclude any other or further exercise thereof
or the exercise of any other right, power, or privilege.  To the fullest extent
permitted by applicable laws, the rights and remedies provided for in this
Agreement are cumulative and not exclusive of any rights and remedies provided
by law.

     6.02.  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of Pledgor and Secured Party and their respective heirs,
successors, and assigns, except that Pledgor may not assign any of its rights or
obligations under this Agreement without the prior written consent of Secured
Party except to the extent permitted by the Note Purchase Agreement.

     6.03.  Amendment; Entire Agreement.  This Agreement, together with any
applicable pledge or other agreement required by applicable laws, embodies the
final, entire agreement among the parties hereto and supersedes any and all
prior commitments, agreements, representations, and understandings, whether
written or oral, relating to the subject matter hereof.  The provisions of this
Agreement may be amended or waived only by an instrument in writing signed by
the parties hereto with the requisite consent of Secured Party as provided in
the Note Purchase Agreement.

                   FIRST AMENDMENT TO STOCK PLEDGE AGREEMENT

     THIS FIRST AMENDMENT TO STOCK PLEDGE AGREEMENT (this "Amendment") dated as
of March ___, 1998, is by and between Boots & Coots International Well Control,
Inc., a Delaware corporation ("Pledgor"), and Geneva Associates, L.L.C.
("Geneva"), as Collateral Agent for the Noteholders (as hereinafter defined)
(the "Secured Party").

                                   RECITALS:

     A.  Pledgor, Geneva and Main Street Merchant Partners II, L.P. ("Main
Street") have entered into that certain Note Purchase Agreement dated as of
January 2, 1998, as amended by that certain First Amendment to Note Purchase
Agreement dated as of March ___, 1998 (the "Note Purchase Agreement Amendment")
(herein, as the same may be further amended, modified, supplemented, extended,
rearranged, and/or restated from time to time, called the "Note Purchase
Agreement"), pursuant to which, upon the terms and conditions therein set forth,
Pledgor has issued its 10.0% Senior Secured Notes due June 15, 1998, in the
aggregate principal amount of $7,250,000 (herein, as the same may be amended,
modified, supplemented, extended, rearranged, and/or restated from time to time,
together with any notes given by Pledgor in extension, replacement,
rearrangement, modification and/or substitution thereof or therefor,
collectively called the "Notes" and any holders of the Notes, collectively
called the "Noteholders").

     B.  Each of Geneva and Main Street requires that this Amendment be entered

           *********************************************************

                                    WARRANT

                                       to

                             PURCHASE COMMON STOCK

                 BOOTS & COOTS INTERNATIONAL WELL CONTROL, INC.

            *******************************************************


This certifies that, for good and valuable consideration, Boots & Coots
International Well Control, Inc., a Delaware corporation (the "Company"), grants
to Main Street Merchant Partners II, L.P. or its registered assigns (the
"Warrantholder"), the right to subscribe for and purchase from the Company
1,200,000 shares (the "Warrant Shares") of common stock, par value $0.00001 per
share (the "Common Stock"), of the Company at the Exercise Price (as defined
herein).  The exercise price shall initially be $2.62 per share of Common Stock,
subject to adjustment as provided in Section 5 (the "Exercise Price").  This
Warrant shall be exercisable from and after 9:00 A.M., Central Standard Time on
January 3, 1998 (the "Initial Exercise Date") to and including 5:00 P.M.,
Central Standard Time on January 3, 2004 (the "Expiration Date").  The Exercise
Price and the number of Warrant Shares are subject to adjustment from time to
time as provided in Section 5.


SECTION 1.  DURATION AND EXERCISE OF WARRANT; LIMITATION ON EXERCISE; TAXES;
            TRANSFER; DIVISIBILITY.

     1.1  DURATION AND EXERCISE OF WARRANT.  This Warrant is immediately
exercisable on 
<PAGE>
 
the Initial Exercise Date and may be exercised, in whole or in part, at any time
from the Initial Exercise Date to the Expiration Date. The rights represented by
this Warrant may be exercised by the Warrantholder of record, in whole or in
part, from time to time, by (a) surrender of this Warrant, accompanied by the
Exercise Form annexed hereto (the "Exercise Form") duly executed by the
Warrantholder of record and specifying the number of Warrant Shares to be
purchased to the Company at the office of the Company located at 5151 San
Felipe, Suite 450, Houston, TX 77056 (or such other office or agency of the
Company as it may designate by notice to the Warrantholder at the address of
such Warrantholder appearing on the books of the Company) during normal business
hours on any day (a "Business Day") other than a Saturday, Sunday or a day on
which the New York Stock Exchange is authorized to close or on which the Company
is otherwise closed for business (a "Nonbusiness Day") on or after 9:00 A.M.
Central Standard Time on the Initial Exercise Date but not later than 5:00 P.M.
on the Expiration Date (or 5:00 P.M. on the next succeeding Business Day, if the
Expiration Date is a Nonbusiness Day), (b) delivery of payment to the Company in
cash or by certified or official bank check in New York Clearing House Funds, of
the Exercise Price for the number of Warrant Shares specified in the Exercise
Form or notice that all or a portion of the next due principal or interest
payment to be paid by the Company to the Warrantholder pursuant to the Note
Purchase Agreement dated as of January 2, 1998, as may be amended from time to
time, on any Note held by Warrantholder is to be applied towards such exercise
(to the extent the Warrantholder is also the holder of such Note), and (c) such
documentation as to the identity and authority of the Warrantholder as the
Company may reasonably request. Such Warrant Shares shall be deemed by the
Company to be issued to the Warrantholder as the record holder of such Warrant
Shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for the Warrant Shares as aforesaid.
Certificates for the Warrant Shares specified in the Exercise Form shall be
delivered to the Warrantholder as promptly as practicable, and in any event
within ten (10) Business Days, thereafter. The stock certificates so delivered
shall be in denominations as may be specified by the Warrantholder and agreed
upon by the Company, and shall be issued in the name of the Warrantholder or, if
permitted by subsection 1.4 and in accordance with the provisions thereof, such
other name as shall be designated in the Exercise Form. If this Warrant shall
have been exercised only in part, the Company shall, at the time of delivery of
the certificates for the Warrant Shares, deliver to the Warrantholder a new
Warrant evidencing the rights to purchase the remaining Warrant Shares, which
new Warrant shall in all other respects be identical with this Warrant. No
adjustments or payments shall be made on or in respect of Warrant Shares
issuable on the exercise of this Warrant for any cash dividends paid or payable
to holders of record of Common Stock prior to the date as of which the
Warrantholder shall be deemed to be the record holder of such Warrant Shares.

     1.2  LIMITATION ON EXERCISE.  If this Warrant is not exercised prior to
5:00 P.M. on the Expiration Date (or the next succeeding Business Day, if the
Expiration Date is a Nonbusiness Day), this Warrant, or any new Warrant issued
pursuant to Section 1.1, shall cease to be exercisable and shall become void,
and all rights of the Warrantholder hereunder shall cease.

     2.3  PAYMENT OF TAXES.  The issuance of certificates for Warrant Shares
shall be made 

                                      -2-
<PAGE>
 
without charge to the Warrantholder for any stock transfer or other issuance tax
in respect thereto; provided, however, that the Warrantholder shall be required
to pay any and all taxes which may be payable in respect to any transfer
involved in the issuance and delivery of any certificates for Warrant Shares in
a name other than that of the then Warrantholder as reflected upon the books of
the Company.

     1.4  RESTRICTIONS ON TRANSFER.  Neither this Warrant nor any of the Warrant
Shares may be transferred or sold except in compliance with applicable United
States federal and state securities laws.

     1.5  DIVISIBILITY OF WARRANT.  This Warrant may be divided into multiple
warrants upon surrender at the principal office of the Company on any Business
Day, without charge to any Warrantholder.

     1.6  CASHLESS EXERCISE.  At the option of the Warrantholder, the
Warrantholder may exercise this Warrant, without a cash payment of the Exercise
Price through (i) application of all or a portion of the next due principal or
interest payment to be paid by Borrower on the Note, or (ii) a reduction in the
number of Warrant Shares issued upon the exercise of the Warrant.  Such
reduction may be effected by designating that the number of the shares of Common
Stock issuable to the Warrantholder upon such exercise shall be reduced by the
number of shares having a fair market value equal to the amount of the total
Exercise Price for such exercise.  In such instance, no cash or other
consideration will be paid by the Warrantholder in connection with such exercise
other than then surrender of the Warrant itself, and no commission or other
remuneration will be paid or given by the Warrantholder or the Company in
connection with such exercise.

SECTION 2.  RESERVATION AND LISTING OF SHARES.

     All Warrant Shares which are issued upon the exercise of the rights
represented by this Warrant shall, upon issuance and payment of the Exercise
Price, be validly issued, fully paid and nonassessable and free from all taxes,
liens, security interests, charges and other encumbrances with respect to the
issue thereof other than taxes in respect of any transfer occurring
contemporaneously with such issue.  During the period within which this Warrant
may be exercised, the Company shall at all times have authorized and reserved,
and keep available free from preemptive rights, a sufficient number of shares of
Common Stock to provide for the exercise of this Warrant, and shall at its
expense use its best efforts to procure such listing thereof as then may be
required on all stock exchanges or automated quotation systems on which the
Common Stock may be listed.

SECTION 3.  EXCHANGE, LOSS OR DESTRUCTION OF WARRANT.

                                      -3-
<PAGE>
 
     If permitted by subsection 1.4 or 1.5, upon surrender of this Warrant to
the Company with a duly executed instrument of assignment and funds sufficient
to pay any transfer tax, the Company shall, without charge, execute and deliver
a new Warrant of like tenor in the name of the assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, the Company will execute and deliver
a new Warrant of like tenor.

SECTION 4.  OWNERSHIP OF WARRANT.

     The Company may deem and treat the person or entity in whose name this
Warrant is registered as the holder and owner hereof (notwithstanding any
notations of ownership or writing hereon made by anyone other than the Company)
for all purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for registration of transfer as provided in
subsections 1.1 and 1.5 or in Section 3.

SECTION 5.  CERTAIN ADJUSTMENTS.

     The Exercise Price at which Warrant Shares may be purchased hereunder and
the number of Warrant Shares to be purchased upon exercise hereof are subject to
change or adjustments as follows:

     5.1  NOTICE OF ADJUSTMENT.  Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail first class, postage prepaid, to all Warrantholders,
notice of such adjustment.

     5.2  PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION.  In case
of any consolidation of the Company with or merger of the Company into another
corporation or in case of any sale, transfer or lease to another corporation of
all or substantially all of the assets or stock of the Company, the Company or
such successor or purchasing corporation, as the case may be, shall execute with
the Warrantholder an agreement providing that the Warrantholder shall have the
right thereafter upon payment of the Exercise Price in effect immediately prior
to such action to receive upon exercise of this Warrant the kind and amount of
shares and other securities and property which such holder would have been
entitled to receive after the happening of such consolidation, merger, sale,
transfer or lease had this Warrant been exercised immediately prior to such
action.  Such agreement shall provide for adjustments, which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 5.
The provisions of this subsection 5.2 shall apply similarly to successive
consolidations, mergers, sales, transfers or leases.

                                      -4-
<PAGE>
 
SECTION 5.3    ADJUSTMENTS TO EXERCISE PRICE.

          (a) Stock Dividends, Distributions or Subdivisions.  In the event the
     Company shall issue additional shares of Common Stock pursuant to a stock
     dividend, stock distribution, subdivision, share split or reclassification,
     the Exercise Price in effect immediately prior to such event shall,
     concurrently with the effectiveness of such event, be proportionately
     decreased.

          (b) Combinations or Consolidations.  In the event the outstanding
     shares of Common Stock shall be combined or consolidated, by
     reclassification, reverse split or otherwise, into a lesser number of
     shares of Common Stock, the Exercise Price in effect immediately prior to
     such event shall, concurrently with the effectiveness of such event, be
     proportionately increased.

          (c) Issuance of Additional Shares of Common Stock.

               (i) In the event the Company shall issue Additional Shares
               (defined below) without consideration or for a consideration per
               share less than the Exercise Price in effect immediately prior to
               the issuance, then the Exercise Price shall be reduced to the
               price at which such Additional Shares are issued.

               (ii) If the Company issues Common Stock for a consideration in
               whole or in part other than cash, the consideration other than
               cash shall be deemed to be the fair value thereof as determined
               by mutual agreement of the Warrantholder and the Company
               irrespective of any accounting treatment.

               (iii)  If the Company issues options to purchase or rights to
               subscribe for Common Stock, securities by their terms convertible
               into or exchangeable for Common Stock or options to purchase or
               rights to subscribe for such convertible or exchangeable
               securities, the following provisions shall apply for all purposes
               of this subsection:

                    (A) The aggregate maximum number of shares of Common Stock
                    deliverable upon exercise (assuming the satisfaction of any
                    conditions to exercisability including, without limitation,
                    the passage of time, but without taking into account
                    potential antidilution adjustments) of such options to
                    purchase or rights to subscribe for Common Stock shall be
                    deemed to have been issued at the time such options or
                    rights were issued and for a 

                                      -5-
<PAGE>
 
                    consideration equal to the consideration, if any, received
                    by the Company upon the issuance of such options or rights
                    plus the exercise price provided in such options or rights
                    (without taking into account potential antidilution
                    adjustments) for the Common Stock covered thereby.

                    (B) The aggregate maximum number of shares of Common Stock
                    deliverable upon conversion of or in exchange (assuming the
                    satisfaction of any conditions to convertibility or
                    exchangeability, including, without limitation, the passage
                    of time, but without taking into account potential
                    antidilution adjustments) for any such conversion or
                    exchange thereof shall be deemed to have been issued at the
                    time such securities were issued or such options or rights
                    were issued and for consideration equal to the
                    consideration, if any, received by the Company for any such
                    securities and related option or rights (excluding any cash
                    received on account of accrued interest or accrued
                    dividends), plus the additional consideration, if any, to be
                    received by the Company (without taking into account
                    potential antidilution adjustments) upon the conversion or
                    exchange of such securities or the exercise of any related
                    options or rights.

                    (C) In the event of any change in the number of shares of
                    Common Stock deliverable or in the consideration payable to
                    the Company upon exercise of such options or rights or upon
                    conversion of or in exchange for such convertible or
                    exchangeable securities, including, but not limited to, a
                    change resulting from the antidilution provisions thereof,
                    the Exercise Price, to the extent it is in any way affected
                    by the issuance of such options, rights or securities, shall
                    be recomputed to reflect such change, but no further
                    adjustment shall be made for the actual issuance of Common
                    Stock or any payment of such consideration upon the exercise
                    of any such options or rights or the conversion or exchange
                    of such securities.

                    (D) Upon the expiration of any such options or rights, the
                    termination of any such rights to convert or exchange or the
                    expiration of any options or rights related to such
                    convertible or exchangeable securities, the Exercise Price,
                    to the extent it is in any way affected by the issuance of
                    such options, rights or securities or options or rights
                    related to such securities, shall be recomputed to reflect
                    the issuance of only the number of shares of 

                                      -6-
<PAGE>
 
                    Common Stock (and convertible or exchangeable securities
                    which remain in effect) actually issued upon the exercise of
                    such options or rights, upon the conversion or exchange of
                    such securities or upon the exercise of the options or
                    rights related to such securities.

                    (E) The number of shares of Common Stock deemed issued and
                    the consideration deemed paid therefor pursuant to
                    subsections 5.3(c)(iii)(A) and (B) shall be appropriately
                    adjusted to reflect any change, termination or expiration of
                    the type described in either subsection 5.3(c)(iii)(C) or
                    (D).

               (iv) "Additional Shares" shall mean any shares of Common Stock
               issued (or deemed to have been issued) pursuant to subsection
               5.3(c)(iii) by the Company on or after the Initial Exercise Date
               other than the Common Stock issued upon exercise of the Warrant.

                         REGISTRATION RIGHTS AGREEMENT


     THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") dated as of January 2,
1998, is by and between Main Street Merchant Partners II, L.P., a Delaware
limited partnership ("Investor"), and Boots & Coots International Well Control,
Inc., a Delaware corporation (the "Company").

                                R E C I T A L S:

     WHEREAS, the Company has requested that Investor purchase certain Notes of
the Company in connection with the purchase by IWC Services, Inc. of the issued
and outstanding stock of ITS Supply Corporation.

     WHEREAS, Investor is willing to purchase certain Notes upon the terms and
conditions of that certain Note Purchase Agreement dated of even date herewith
(the "Note Purchase Agreement"), by and between the Company and Investor, and
subject to the representations, warranties, covenants and agreements set forth
herein and therein:

     WHEREAS, it is a material inducement and a precondition to the entering
into of the Note Purchase Agreement by Investor that the Company enter into this
Agreement;

     NOW, THEREFORE, in consideration of the terms and conditions contained
herein and of the purchase of Notes by Investor, the parties hereto, intending
to be legally bound hereby, agree as follows:

                                   ARTICLE I

                              REGISTRATION RIGHTS

     Section 1.1  Requested Registration.

     (a)  If, at any time, the Company shall receive from Investor a written
request that the Company effect a registration under the Securities Act for the
sale of at least 25% of the Registrable Securities (as defined below) held or
obtainable by all of the Holders, the Company shall:

     (i) within ten (10) days after receipt of such written request, give
written notice of the proposed registration to all other Holders (if any); and

     (ii) as soon as practicable use its best efforts to register (including,
without limitation, the execution of an undertaking to file post-effective
amendments and any other governmental requirements) all Registrable Securities
which a Holder requests to be registered and all Registrable Securities which
any other Holder requests to be registered within twenty (20) days after receipt
of such written notice from the Company; provided, that the Company shall 
<PAGE>
 
not be obligated to file any additional registration statement pursuant to this
Section 1.1 after the Company has effected two such registrations at the request
of Investor and such registrations have been declared or ordered effective.

     Subject to the foregoing, the Company shall file a registration statement
covering the Registrable Securities so requested to be registered as soon as
practicable, but in any event within sixty (60) days after receipt of the
request or requests of a Holder and shall use its best efforts to have such
registration statement promptly declared effective by the Securities Exchange
Commission whether or not all Registrable Securities requested to be registered
can be included.  If, however, the Company shall furnish to such Holders a
certificate signed by the President of the Company stating that in the good-
faith judgment of the Board of Directors it would be materially detrimental to
the Company and its shareholders for such registration statement to be filed
within such sixty-day (60-day) period and it is therefore deferring the filing
of such registration statement, the Company shall have an additional period of
not more than sixty (60) days after the expiration of the initial sixty-day (60-
day) period within which to file such registration statement; provided, that
during such time the Company may not file a registration statement for
securities to be issued and sold for its own account or the account of an other
of its shareholders.

     (b)  If a Holder intends to distribute the Registrable Securities covered
by its request by means of an underwriting, such Holder shall so advise the
Company as part of its request and the Company shall include such information in
the written notice referred to in subsection 1.1(a)(i).  The underwriter may be
selected by the Holders electing to sell their Registrable Securities, subject
to the reasonable approval of the Company.  The right of any Holder to
registration pursuant to this Section 1.1 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.  The
Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting.  Notwithstanding any other provisions of this Section 1.1, if the
representative of the underwriter advises the Company and the Holder(s) in
writing that marketing factors require a limitation on the number of shares to
be underwritten (a "Cutback"), the number of shares to be included in the
underwriting or registration shall be allocated first to the Holders, without
limitation,  and thereafter shall be allocated among the Company and the other
holders requesting inclusion in the registration pro rata on the basis of the
number of shares each requesting other holder (or the Company, as the case may
be) requests to be included bears to the total number of shares of all
requesting other holders (and the Company) that have been requested to be
included in such registration.  If a person who has requested inclusion in such
registration as provided above does not agree to the terms of any such
underwriting, such person shall be excluded therefrom by written notice from the
Company, the underwriter or the Holder(s).  The securities so excluded shall
also be withdrawn from registration.

     (c) If, at the time any written request for registration is received by the
Company pursuant to this Section, the Company has determined to proceed with the
actual preparation and filing of a registration statement under the Securities
Act in connection with the proposed offer 

                                      -2-
<PAGE>
 
and sale for cash of any of its securities by it or any of its security holders,
or in the event that Section 1.3 hereof is applicable, then such written request
shall be deemed to have been given pursuant to Section 1.2 and Section 1.3
hereof, as the case may be, rather than this Section 1.1, and the rights of the
Holders covered by such written request shall be governed by Section 1.2 or
Section 1.3, as the case may be.

     Section 1.2   Piggyback Registration.  If at any time or from time to time,
the Company shall determine to register the sale of any of its securities, for
its own account or the account of any of its shareholders, other than a
registration relating solely to an employee benefit plan or a registration
relating solely to a transaction under Rule 145 of the Securities Act, the
Company will:

               (i) give to each Holder written notice thereof as soon as
          practicable prior to filing the registration statement; and

               (ii) on behalf of all entities requesting inclusion in such
          registration, include such securities in the offering and may
          condition such offer on their acceptance of any other reasonable
          conditions (including, without limitation, if such offering is
          underwritten, that such requesting holders agree in writing to enter
          into an underwriting agreement with usual and customary terms).  If
          the representative of the underwriter advises the Company in writing
          that marketing factors require a Cutback, the number of shares to be
          included in the underwriting or registration shall be allocated first
          to the Company, and thereafter shall be allocated among the other
          holders requesting inclusion in the registration pro rata on the basis
          of the number of shares each requesting other holder requests to be
          included bears to the total number of shares of all requesting other
          holders that have been requested to be included in such registration.
          If a person who has requested inclusion in such registration as
          provided above does not agree to the terms of any such underwriting,
          such person shall be excluded therefrom by written notice from the
          Company or the underwriter.  The securities so excluded shall also be
          withdrawn from registration.

     Section 1.3  Form S-2 or Form S-3.

          (a) Each Holder will have the right to request and have effected
     unlimited registrations of shares of its Registrable Securities on Form S-2
     or Form S-3.

          (b) Upon written request of a Holder delivered to the Company, the
     Company will notify each other Holder of such request within three (3) days
     after the receipt of such request.  Each of such other Holders shall have
     three (3) days after receipt of such notice from the Company to request
     that all or any portion of its Registrable Securities be included in such
     registration.  After the expiration of all such request and notice periods
     under this Section, the Company will use all reasonable efforts to cause
     the registration of all Registrable Securities on Form S-2 or such
     successor form or Form S-3 

                                      -3-
<PAGE>
 
     or such successor form to the extent requested by such Holders.

          (c) Any registration statement filed pursuant to this Section may
     include other securities of the Company, with respect to which "piggyback"
     registration rights have been granted, and may include securities of the
     Company being sold for the account of the Company; provided, however, that
     any Cutback shall be dealt with in the same manner as provided in Section
     1.1.

     Section 1.4  Registrable Securities.  For the purposes of this Section 1,
the term "Registrable Securities" shall mean any shares of voting Common Stock
issuable to a Holder upon exercise of  the Warrant, any shares of Common Stock
issued to a Holder as a dividend on the Warrant Shares, and any other shares of
Common Stock distributable on, with respect to, or in substitution for such
Registrable Securities, including those which have been transferred as permitted
under this Agreement, except for those that have been sold or transferred
pursuant to an effective registration statement or pursuant to Rule 144 under
the Securities Act.

     Section 1.5  Procedure for Registration.  Whenever the Company is required
under this Agreement to register Common Stock, it agrees do the following:

          (a) Use all reasonable efforts to prepare, as soon as is feasible, for
     filing with the Securities and Exchange Commission a registration statement
     and such amendments and supplements to said registration statement and the
     prospectus as may be necessary to keep the registration statement effective
     and to comply with the provisions of the Securities Act for the period
     necessary to complete the proposed public offering;

          (b) Furnish to each selling Holder such copies of each preliminary and
     final prospectus and such other documents as such holder may reasonably
     request to facilitate the public offering of its Registrable Securities;

          (c) Enter into any underwriting agreement with provisions reasonably
     required by the proposed underwriter for the selling holders, if any; and

          (d) Use all reasonable efforts to register or qualify the Registrable
     Securities covered by the registration statement under the securities or
     "blue-sky" laws of such jurisdictions as any selling Holder may reasonably
     request, although the Company will not have to register in any states that
     require it to qualify to do business or subject itself to general service
     of process, and for a registration under Section 1.2. The Company will not
     be required to register in more states than are necessary to permit the
     sale of the securities.

     Section 1.6.  Indemnification.

          (a)  Subject to applicable law, the Company will indemnify each Holder
and each person controlling such Holder against all claims, losses, damages and
liabilities, including legal 

                                      -4-
<PAGE>
 
and other expenses reasonably incurred, arising out of any untrue or allegedly
untrue statement of a material fact contained in the registration statement, or
any omission or alleged omission to state a material fact required to be stated
in the registration statement or necessary to make the statements not
misleading, or arising out of any violation by the Company of the Securities
Act, any state securities or "blue-sky" laws or any applicable rule or
regulation.

          (b)  Subject to applicable law, each Holder will indemnify the
Company, and each person controlling the Company, against all claims, losses,
damages and liabilities, including legal and other expenses reasonably incurred,
arising out of any untrue or allegedly untrue statement of a material fact
contained in the registration statement, or required to be stated in the
registration statement or necessary to make the statements contained therein not
misleading, to the extent, but only to the extent, that such untrue statement or
omission is contained in any information or affidavit furnished in writing by
such Holder to the Company specifically for inclusion in such registration
statement.  In no event shall the liability of such Holder under this paragraph
be greater in amount than the dollar amount of the proceeds received by such
Holder upon the sale of the Common Stock pursuant to the registration statement
giving rise to such indemnification obligation.

     Section 1.7  Transfer of Registration Rights.  The registration rights of a
Holder under Section 1 may be transferred to any transferee of Registrable
Securities.  Any such transferee will be deemed to be a Holder for purposes of
this Agreement, and as a condition precedent to transfer, such transferee must
agree to be bound by the terms of this Agreement.

     Section 1.8  Obligations of a Holder and Others in a Registration.  Each
Holder  agrees to timely furnish such information regarding such person and the
securities sought to be registered and to take such other action as the Company
may reasonably request, including the entering into of agreements and the
providing of documents, in connection with the registration or qualification of
such securities and/or the compliance of such registration statement with all
applicable laws.  Each Holder severally agrees that, in connection with any
offering undertaken pursuant to Section 1.2 or Section 1.3, the Company shall
have the right to, if it deems an underwriter or underwriters necessary or
appropriate, designate such underwriter(s); provided, however, that if the
Company does not within sixty (60) days from the date of the last written notice
of the Holder(s) delivered pursuant to Section 1.2 or Section 1.3, as the case
may be, designate such underwriter(s) in writing to the Holder(s), the Holder(s)
shall have the right to designate their own underwriter(s).  If the registration
involves an underwriter, each Holder agrees, upon the request of such
underwriter, not to sell any unregistered securities of the Company for a period
of one hundred eighty (180)  days following the effective date of the
registration statement for such offering and to enter into an underwriting
agreement with such underwriters containing usual and customary terms and
provisions.

     Section 1.9  Limitations on Subsequent Registration Rights.  The Company
will not, without the prior written consent of  Investor, enter into any
agreement with any holder or prospective holder of any securities of the Company
which would allow such holder or prospective holder to make a demand
registration which could result in such registration 

                                      -5-
<PAGE>
 
statement being declared effective prior to the 180th day subsequent to the
effective date of any registration effective pursuant to Section 1.2 or Section
1.3. If the Company grants any subsequent registration rights more favorable
than the registration rights granted to Investor in this Section, the Company
will also grant the more favorable registration rights to Investor.

     Section 1.10  Expenses of Registration.  All expenses incurred in
connection with registrations pursuant to this Agreement, including, without
limitation, all registration, federal and state filing and qualification fees,
printing expenses, fees and disbursements of counsel for the Company and one
counsel for the Holders and expenses of any special audits of the Company's
financial statements incidental to or required by such registration, shall be
borne by the Company, except that the Company shall not be required to pay
underwriters' fees, discounts or commissions relating to Registrable Securities
being sold by any Holders.


                                   ARTICLE II

                        BOARD OF DIRECTOR REPRESENTATIVE

     At the election of Investor or Geneva Associates, L.L.C. ("Geneva"), for a
period of six (6) years from the date hereof, the Company shall elect a

Company's Board of Directors as soon as possible after the date hereof.  Until
such time, Investor and Geneva shall have Board of Director visitation rights
which will entitle it to participation in (and receive copies of all materials
distributed at) all meetings of the Board of Directors and any committees
thereof.

                                  ARTICLE III

                                 MISCELLANEOUS

     Section 3.1  Modification of Agreement, Sale of Interest.

     (a) This Agreement may not be modified, altered or amended, except by an
agreement in writing signed by Investor and the Company.  The Company may not
sell, assign or transfer this Agreement, or the Warrant, or any portion thereof,
including, without limitation, any of the Company's rights, titles, interests,
remedies, powers, obligations and/or duties hereunder or thereunder.  Investor
may, subject to the provisions of the Section 3.1(b) below, assign, transfer or
otherwise dispose of, at any time or times hereafter, this Agreement or the
Warrant, or any portion hereof or thereof, including, without limitation, such
party's rights, title, interest, remedies, powers, and/or duties hereunder or
thereunder, and such transferee or assignee must agree to be bound by the terms
and conditions of this Agreement.  This Agreement and Warrant shall be binding
upon and inure to the benefit of the successors and permitted assigns of
Investor.

     (b) Anything to the contrary in this Agreement notwithstanding, if Investor
has assigned any of its rights as permitted hereunder, the rights of Investor,
including the right to

                                      -6-
<PAGE>
 
grant any consent or waiver or to enter into any amendment to this Agreement may
be exercised only by the holders of the majority in interest of the Warrant
Shares issued or issuable under the Warrant and such action taken by such
majority shall be binding on all others, including Investor and its successors
and permitted assigns. Investor will give notice to Borrower of any such
assignment within a reasonable period thereafter.

     Section 3.2  Expenses and Attorney's Fees.  If, at any time or times,
whether prior or subsequent to the date hereof, Investor employs counsel for
advice or other representation or incurs reasonable legal and/or other costs and
expenses in connection with:

     (a) the negotiation, preparation or execution of this Agreement or any
amendment of or modification of this Agreement;

     (b) any litigation, contest, dispute, suit, proceeding or action (whether
instituted by Investor, the Company or any other person) in any way relating to
this Agreement or the Warrant, unless a court of competent jurisdiction finds in
favor of the Company as the prevailing party, and awards court costs and
attorneys' fees to the such prevailing party; or

     (c) any attempt to enforce any rights of Investor or any participant
against the Company or any other person that may be obligated to Investor by
virtue of this Agreement or the Warrant in accordance with the terms of this
Agreement;

then, in any such event, the reasonable attorneys' fees arising from such
services and all reasonable expenses, costs, charges, and fees of counsel or of
Investor in any way or respect arising in connection with or relating to any of
the events or actions described in this subsection shall be payable on demand by
the Company, to Investor.

     Section 3.3  Waiver by Investor.  Investor's failure, at any time or times
hereafter, to require strict performance by the Company of any provision of this
Agreement or the Warrant shall not waive, affect or diminish any right of
Investor thereafter to demand strict compliance and performance therewith.  None
of the undertakings, agreements, warranties, covenants and representations of
the Company or any of its Subsidiaries contained in this Agreement, the Warrant,
or the other Documents shall be deemed to have been suspended or waived by
Investor, unless such suspension or waiver is by an instrument in writing signed
by an officer of Investor and specifying such suspension or waiver.

     Section 3.4  Severability.  Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     Section 3.5  Parties.  This Agreement, the Warrant and the Other Agreements
shall be binding upon and inure to the benefit of the successors and permitted
assigns of Borrower, each of its Subsidiaries, the Company and Investor.

                                      -7-

     Section 3.6  Entire Agreement; Conflict of Terms.  This Agreement, the
Warrant and the other Documents constitute the entire agreement of the parties
with respect to the Warrant and may not be modified or supplemented by any prior
or contemporaneous oral understanding.

     Section 3.7  Equitable Relief.  The Company recognized that, in the event
the Company fails to perform, observe or discharge any of its obligations or
liabilities under this Agreement, any remedy of law may prove to be inadequate
relief to Investor, therefore, the Company agrees that Investor, if Investor so
requests, shall be entitled to temporary and permanent injunctive relief in any
such case without the necessity of proving actual damages.

     Section 3.8  Governing Law; Jurisdiction; Venue; Waiver of Jury Trial and
Service of Process.  THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE AT TEXAS

<PAGE>
 
   The Plan shall be administered by a Committee of the Board of Directors
consisting of two or more persons, each of whom shall be a "disinterested
person" within the meaning of Rule 16b-3(c)(2)(i) promulgated under Section 16
of the Exchange Act. The Committee shall from time to time designate the
employees of the Company who shall be granted Incentive Awards and the amount
and type of such Incentive Awards.

   The Committee shall have full authority to administer the Plan, including
authority to interpret and construe any provision of the Plan and the terms of
any Incentive Award issued under it and to adopt such rules and regulations for
administering the Plan as it may deem necessary. Decisions of the Committee
shall be final and binding on all parties.

   The Committee may, in its absolute discretion (i) accelerate the date on
which any Option granted under the Plan becomes exercisable, (ii) extend the
date on which any Option granted under the Plan ceases to be exercisable, (iii)
accelerate the Vesting Date or Issue Date, or waive any condition imposed
pursuant to Section 7(b) hereof, with respect to any share of Restricted Stock
granted under the Plan and (iv) accelerate the Vesting Date or waive any
condition imposed pursuant to Section 8 hereof, with respect to any share of
Phantom Stock granted under the Plan.

   In addition, the Committee may, in its absolute discretion, grant Incentive
Awards to Participants on the condition that such Participants surrender to the
Committee for cancellation such other Incentive Awards (including, without
limitation, Incentive Awards with higher exercise prices) as the Committee
specifies. Notwithstanding Section 3 hereof, Incentive Awards granted on the
condition of surrender of outstanding Incentive Awards shall not count against
the limits set forth in such Section 3 until such time as such Incentive Awards
are surrendered.

   Whether an authorized leave of absence, or absence in military or government
service, shall constitute termination of employment shall be determined by the
Committee in its absolute discretion.

   No member of the Committee shall be liable for any action, omission, or
determination relating to the Plan, and the Company shall indemnify and hold
harmless each member of the Committee and each other director or employee of the
Company to whom any duty or power relating to the administration or
interpretation of the Plan has been delegated from and against any cost or
expense (including attorneys' fees) or liability (including any sum paid in
settlement of a claim with the approval of the Committee) arising out of any
action, omission or determination relating to the Plan, unless, in either case,
such action, omission or determination was taken or made by such member,
director or employee in bad faith and without reasonable belief that it was in
the best interests of the Company.

5. ELIGIBILITY

   The persons who shall be eligible to receive Incentive Awards pursuant to the
Plan shall be such full-time employees of the Company as the Committee, in its
absolute discretion, shall select from time to time. Notwithstanding the
generality of the foregoing, no employee of the Company shall be eligible to
receive Incentive Awards pursuant to this Plan if the employee is also entitled
to receive an Incentive Award under the terms of his employment agreement with
the Company, or any specialty Incentive Stock Plan adopted after the date
hereof, unless such employment agreement or specialty plan expressly provides
otherwise.

   such Non-Qualified Stock Option is granted; provided, that such price may not
   be less than the minimum price required by law. Except as provided in Section
   6(d) hereof, the exercise price of any Incentive Stock Option granted under
   the Plan shall be not less than 100% of the Fair Market Value of a share of
   Common Stock on the date on which such Incentive Stock Option is granted.

   (c) Term and Exercise of Options

       (1) Each Option shall be exercisable on such date or dates, during such
       period and for such number of shares of Common Stock as shall be
       determined by the Committee on the day on which such Option is granted
       and set forth in the agreement evidencing the Option; provided, however,
       that no Option shall be exercisable after the expiration of ten years
       from the date such Option was granted; and, provided, further, that each
       Option shall be subject to earlier termination, expiration or
       cancellation as provided in the Plan.

       (2) Each Option shall be exercisable in whole or in part with respect to
       whole shares of Common Stock. The partial exercise of an Option shall not
       cause the expiration, termination or cancellation of the remaining
       portion thereof. Upon the partial exercise of an Option, the agreement
       evidencing such Option shall be returned to the Participant exercising
       such Option together with the delivery of the certificates described in
       Section 6(c)(5) hereof.

       (3) An Option shall be exercised by delivering notice to the Company's
       principal office, to the attention of its Secretary, no fewer than five
       business days in advance of the effective date of the proposed exercise.
       Such notice shall be accompanied by the agreement evidencing the Option,
       shall specify the number of shares of Common Stock with respect to which
       the Option is being exercised and the effective date of the proposed
       exercise, and shall be signed by the Participant. The Participant may
       withdraw such notice at any time prior to the close of business on the
       business day immediately preceding the effective date of the proposed
       exercise, in which case such agreement shall be returned to the
       Participant. Payment for shares of Common Stock purchased upon the
       exercise of an Option shall be made on the effective date of such
       exercise either (i) in cash, by certified check, bank cashier's check or
       wire transfer or (ii) subject to the approval of the Committee, in shares
       of Common Stock owned by the Participant and valued at their Fair Market
       Value on the effective date of such exercise, or (iii) partly in shares
       of Common Stock with the balance in cash, by certified check, bank
       cashier's check or wire transfer. Any

                                       5
<PAGE>
 
       payment in shares of Common Stock shall be effected by the delivery of
       such shares to the Secretary of the Company, duly endorsed in blank or
       accompanied by stock powers duly executed in blank, together with any
       other documents and evidences as the Secretary of the Company shall
       require from time to time.

       (4) Any Option granted under the Plan may be exercised by a broker-dealer
       acting on behalf of a Participant if (i) the broker-dealer has received
       from the Participant or the Company a duly endorsed agreement evidencing
       such Option and instructions signed by the Participant requesting the
       Company to deliver the shares of Common Stock subject to such Option to
       the broker-dealer on behalf of the Participant and specifying the account
       into which such shares should be deposited, (ii) adequate provision has
       been made with respect to the payment of any withholding taxes due upon
       such exercise and (iii) the broker-dealer and the Participant have
       otherwise complied with Section 220.3(e)(4) of Regulation T, 12 CFR Part
       220.

       (5) Certificates for shares of Common Stock purchased upon the exercise
       of an Option shall be issued in the name of the Participant and delivered
       to the Participant as soon as practicable following the effective date on
       which the Option is exercised; provided, however, that such delivery
       shall be effected for all purposes when a stock transfer agent of the
       Company shall have deposited such certificates in the United States mail,
       addressed to the Participant.

       (6) During the lifetime of a Participant each Option granted to him shall
       be exercisable only by him. No Option shall be assignable or transferable
       otherwise than by will or by the laws of descent and distribution.

   (d) Limitations on Grant of Incentive Stock Options

       (1) The aggregate Fair Market Value of shares of Common Stock with
       respect to which "incentive stock options" (within the meaning of Section
       422, without regard to Section 422(d) of the Code) are exercisable for
       the first time by a Participant during any calendar year under the Plan
       (and any other stock option plan of the Company, or any subsidiary of the
       Company shall not exceed $100,000. Such Fair Market Value shall be
       determined as of the date on which each such Incentive Stock Option is
       granted. If such aggregate Fair Market Value of shares of Common Stock
       underlying such Incentive Stock Options exceeds $100,000, then Incentive
       Stock Options granted hereunder to such Participant shall, to the extent
       and in the order required by Regulations promulgated under the Code (or
       any other authority having the force of Regulations), automatically be
       deemed to be Non-Qualified Stock Options, but all other terms and
       provisions of such Incentive Stock Options shall remain unchanged. In the
       absence of such Regulations (and authority), or if such Regulations (or
       authority) require or permit a designation of the options which shall
       cease to constitute Incentive Stock Options, Incentive Stock Options
       shall, to the extent of such excess and in the order in which they were
       granted, automatically be deemed to be Non-Qualified Stock Options, but
       all other terms and provisions of such Incentive Stock Options shall
       remain unchanged.

       (2) No Incentive Stock Option may be granted to an individual if, at the
       time of the proposed grant, such individual owns, directly or indirectly
       (based on the attribution rules in Section 424(d) of the Code) stock
       possessing more than ten

                                       6
<PAGE>
 
       percent of the total combined voting power of all classes of stock of the
       Company or any of its subsidiaries, unless (i) the exercise price of such
       Incentive Stock Option is at least 110% of the Fair Market Value of a
       share of Common Stock at the time such Incentive Stock Option is granted
       and (ii) such Incentive Stock Option is not exercisable after the
       expiration of five years from the date such Incentive Stock Option is
       granted.

   (e) Effect of Termination of Employment

       (1) If the employment of a Participant with the Company shall terminate
       for any reason other than Cause, "permanent and total disability (within
       the meaning of Section 22(e)(3) of the Code) or the death of the
       Participant (i) Options granted to such Participant, to the extent that
       they were exercisable at the time of such termination, shall remain
       exercisable until the expiration of one month after such termination, on
       which date they shall expire, and (ii) Options granted to such
       Participant, to the extent that they were not exercisable at the time of
       such termination, shall expire at the close of business on the date of
       such termination; provided, however, that no Option shall be exercisable
       after the expiration of its term.

       (2) If the employment of a Participant with the Company shall terminate
       as a result of the "permanent and total disability (within the meaning of
       Section 22(e)(3) of the Code) of the Participant, the voluntary
       retirement of the Participant in accordance with the Company's retirement
       policy as then in effect or the death of the Participant (i) Options
       granted to such Participant, to the extent that they were exercisable at
       the time of such termination, shall remain exercisable until the
       expiration of one year after such termination, on which date they shall
       expire, and (ii) Options granted to such Participant, to the extent that
       they were not exercisable at the time of such termination, shall expire
       at the close of business on the date of such termination; provided,
       however, that no Option shall be exercisable after the expiration of its
       term.

       (3) In the event of the termination of a Participant's employment for
       Cause, all outstanding Options granted to such Participant shall expire
       at the commencement of business on the date of such termination.

   (f) Acceleration of Exercise Date Upon Change in Control

   Upon the occurrence of a Change in Control, each Option granted under the
   Plan and outstanding at such time shall become fully and immediately
   exercisable and shall remain exercisable until its expiration, termination or
   cancellation pursuant to the terms of the Plan.

Restricted Stock shall comply with and be subject to the following terms and
conditions:

   (a) Issue Date and Vesting Date

   At the time of the grant of shares of Restricted Stock, the Committee shall
   establish an Issue Date or Issue Dates and a Vesting Date or Vesting Dates

<PAGE>
 
   Issue Date and/or Vesting Date for each class. Except as provided in Sections
   7(c) and 7(f) hereof, upon the occurrence of the Issue Date with respect to a
   share of Restricted Stock, a share of Restricted Stock shall be issued in
   accordance with the provisions of Section 7(d) hereof. Provided that all
   conditions to the vesting of a share of Restricted Stock imposed pursuant to
   Section 7(b) hereof are satisfied, and except as provided in Sections 7(c)
   and 7(f) hereof, upon the occurrence of the Vesting Date with respect to a
   share of Restricted Stock, such share shall vest and the restrictions of
   Section 7(c) hereof shall cease to apply to such share.

   (b) Conditions to Vesting

   At the time of the grant of shares of Restricted Stock, the Committee may
   impose such restrictions or conditions, not inconsistent with the provisions
   hereof, to the vesting of such shares as it in its absolute discretion deems
   appropriate. By way of example and not by way of limitation, the Committee
   may require, as a condition to the vesting of any class or classes of shares
   of Restricted Stock, that the Participant or the Company achieve certain
   performance criteria, such criteria to be specified by the Committee at the
   time of the grant of such shares.

   (c) Restrictions on Transfer Prior to Vesting

   Prior to the vesting of a share of Restricted Stock, no transfer of a
   Participant's rights with respect to such share, whether voluntary or
   involuntary, by operation of law or otherwise, shall vest the transferee with
   any interest or right in or with respect to such share, but immediately upon
   any attempt to transfer such fights, such share, and all of the rights
   related thereto, shall be forfeited by the Participant and the transfer shall
   be of no force or effect.

   (d) Issuance of Certificates

       (1) Except as provided in Sections 7(c) or 7(f) hereof, reasonably
       promptly after the Issue Date with respect to shares of Restricted Stock,
       the Company shall cause to be issued a stock certificate, registered in
       the name of the Participant to whom such shares were granted, evidencing
       such shares: provided, that the Company shall not cause to be issued such
       a stock certificates unless it has received a stock power duly endorsed
       in blank with respect to such shares. Each such stock certificate shall
       bear the following legend:

         The transferability of this certificate and the shares of stock
         represented hereby are subject to the restrictions, terms and
         conditions (including forfeiture and restrictions against transfer)
         contained in the IWC Services, Inc.--1996 Incentive Stock Plan and an
         Agreement entered into between the registered owner of such shares and
         IWC Services, Inc. A copy of the Plan and Agreement is on file in the
         office of the Secretary of IWC Services, Inc., 2800 Post Oak Boulevard,
         Suite 6300, Houston, Texas 77056.
          
       Such legend shall not be removed from the certificate evidencing such
       shares until such shares vest pursuant to the terms hereof.

       (2) Each certificate issued pursuant to Paragraph 7 (d)(1) hereof,
       together with the stock powers relating to the shares of Restricted Stock
       evidenced by such certificate, shall be held by the Company. The Company
       shall issue to the Participant a receipt evidencing the certificates held
       by it which are registered in the name of the

                                       8
<PAGE>
 
       Participant.

   (e) Consequences Upon Vesting

   Upon the vesting of a share of Restricted Stock pursuant to the terms hereof,
   the restrictions of Section 7(c) hereof shall cease to apply to such share.
   Reasonably promptly after a share of Restricted Stock vests pursuant to the
   terms hereof, the Company shall cause to be issued and delivered to the
   Participant to whom such shares were granted, a certificate evidencing such
   share, free of the legend set forth in Paragraph 7 (d)(1) hereof, together
   with any other property of the Participant held by Company pursuant to
   Section 7(d) hereof, provided, however, that such delivery shall be effected
   for all purposes when the Company shall have deposited such certificate and
   other property in the United States mail, addressed to the Participant.

   (f) Effect of Termination of Employment

       (1) If the employment of a Participant with the Company shall terminate
       for any reason other than Cause prior to the vesting of shares of
       Restricted Stock granted to such Participant, a portion of such shares,
       to the extent not forfeited or canceled on or prior to such termination
       pursuant to any provision hereof, shall vest on the date of such
       termination. The portion referred to in the preceding sentence shall be
       determined by the Committee at the time of the grant of such shares of
       Restricted Stock and may be based on the achievement of any conditions
       imposed by the Committee with respect to such shares pursuant to Section
       7(b). Such portion may equal zero.

       (2) In the event of the termination of a Participant's employment for
       Cause, all shares of Restricted Stock granted to such Participant which
       have not vested as of the date of such termination shall immediately be
       forfeited.

   (g) Effect of Change in Control

   which have not theretofore vested (including those with respect to which the
   Issue Date has not yet occurred) shall immediately vest.

8. PHANTOM STOCK

   The Committee may grant shares of Phantom Stock pursuant to the Plan. Each
grant of shares of Phantom Stock shall be evidenced by an agreement in such form
as the Committee shall from time to time approve. Each grant of shares of
Phantom Stock shall comply with and be subject to the following terms and
conditions:

   (a) Vesting Date

   At the time of the grant of shares of Phantom Stock, the Committee shall
   establish a Vesting Date or Vesting Dates with respect to such shares. The
   Committee may divide such shares into classes and assign a different Vesting
   Date for each class. Provided that all conditions to the vesting of a share
   of Phantom Stock imposed pursuant to Section 8(c) hereof are satisfied, and

   to receive in cash, within 90 days of the date on which such share vests, an
   amount in cash in a lump sum equal to the sum of (i) the Fair Market Value of
   a share of Common Stock

                                       9
<PAGE>
 
   of the Company on the date on which such share of Phantom Stock vests and
   (ii) the aggregate amount of cash dividends paid with respect to a share of
   Common Stock of the Company during the period commencing on the date on which
   the share of Phantom Stock was granted and terminating on the date on which
   such share vests.

   At the time of the grant of shares of Phantom Stock, the Committee may impose
   such restrictions or conditions, not inconsistent with the provisions hereof,
   to the vesting of such shares as it, in its absolute discretion deems
   appropriate. By way of example and not by way of limitation, the Committee
   may require, as a condition to the vesting of any class or classes of shares
   of Phantom Stock, that the Participant or the Company achieve certain
   performance criteria, such criteria to be specified by the Committee at the
   time of the grant of such shares.

   (d) Effect of Termination of Employment

       (1) If the employment of a Participant with the Company shall terminate
       for any reason other than Cause prior to the vesting of shares of Phantom
       Stock granted to such Participant a portion of such shares, to the extent
       not forfeited or canceled on or prior to such termination pursuant to any
       provision hereof, shall vest on the date of such termination. The portion
       referred to in the preceding sentence shall be determined by the
       Committee at the time of the grant of such shares of Phantom Stock and
       may be based on the achievement of any conditions imposed by the
       Committee with respect to such shares pursuant to Section 8(c). Such
       portion may equal zero.

       (2) In the event of the termination of a Participant's employment for

amounts as it shall determine from time to time. A Stock Bonus shall be paid at
such time and subject to such conditions as the Committee shall determine at the
time of the grant of such Stock Bonus. Certificates for shares of Common Stock

such grant was made and delivered to such Participant as soon as practicable
after the date on which such Stock Bonus is required to be paid.

grant of Restricted Stock or Stock Bonus or at any time thereafter, a cash
bonus, payable promptly after the date on which the Participant is required to

Restricted Stock or Stock Bonus, in such amounts as the Committee shall
determine from time to time; provided, however, that in no event shall the

Restricted Stock or Stock Bonus on such date. A Cash Bonus shall be subject to
such conditions as the Committee shall determine at the time of the grant of
such Cash Bonus.

11.  ADJUSTMENT UPON CHANGES IN COMMON STOCK

     (a) Outstanding Restricted Stock and Phantom Stock

     Unless the Committee in its absolute discretion otherwise determines, if a
     Participant receives any securities or other property (including dividends
     paid in cash) with respect to a share of Restricted Stock, the Issue Date
     with respect to which occurs prior to such event, but which has not vested
     as of the date of such event, as a result of any dividend, stock split
     recapitalization, merger, consolidation, combination, exchange of shares or
     otherwise, such securities or other property will not vest until such share
     of Restricted Stock vests, and shall be held by the Company pursuant to
     Paragraph 7 (d) (2) hereof. The Committee may, in its absolute discretion,
     adjust any grant of shares of Restricted Stock, the Issue Date with respect
     to which has not occurred as of the date of the occurrence of any of the
     following events, or any grant of shares of Phantom Stock, to reflect any
     dividend, stock split, recapitalization, merger, consolidation,
     combination, exchange of shares or similar corporate change as the
     Committee may deem appropriate to prevent the enlargement or dilution of
     rights of Participants under the grant.

     (b) Outstanding Options, Increase or Decrease in Issued Shares Without
     Consideration.

     Subject to any required action by the shareholders of the Company, in the
     event of any increase or decrease in the number of issued shares of Common
     Stock resulting from a subdivision or consolidation of shares of Common
     Stock or the payment of a stock dividend (but only on the shares of Common
     Stock), or any other increase or decrease in the number of such shares
     effected without receipt of consideration by the Company, the Committee
     shall proportionally adjust the number of shares and the exercise price per
     share of Common Stock subject to each outstanding Option.

     (c) Outstanding Options, Certain Mergers
 
     Subject to any required action by the shareholders of the Company, if the
     Company shall be the surviving corporation in any merger or consolidation
     (except a merger of consolidation as a result of which the holders of
     shares of Common Stock receive securities of another corporation), each
     Option outstanding on the date of such merger or consolidation shall
     entitle the Participant to acquire upon exercise the securities which a
     holder of the number of shares of Common Stock subject to such Option would
     have received in such merger or consolidation.

     (d) Outstanding Options, Certain Other Transactions

     In the event of a dissolution or liquidation of the Company, a sale of all
     or substantially all of the Company's assets, a merger or consolidation
     involving the Company in which the Company is not the surviving corporation
     or a merger or consolidation involving the Company in which the Company is
     the surviving corporation but the holders of shares of Common Stock receive
     securities of another corporation and/or other property, including cash,
     the Committee shall, in its absolute discretion, have the power to:

         (1) cancel, effective immediately prior to the occurrence of such
         event, each 

                                       11
<PAGE>
 
         Option outstanding immediately prior to such event (whether or not then
         exercisable), and, in full consideration of such cancellation, pay to
         the Participant to whom such Option was granted an amount in cash, for
         each share of Common Stock subject to such Option equal to the excess
         of (A) the value, as determined by the Committee in its absolute
         discretion, of the property (including cash) received by the holder of
         a share of Common Stock as a result of such event over (B) the exercise
         price of such Option; or

         (2) provide for the exchange of each Option outstanding immediately
         prior to such event (whether or not then exercisable) for an option on
         some or all of the property for which such Option is exchanged and,
         incident thereto, make an equitable adjustment as determined by the
         Committee in its absolute discretion in the exercise price of the
         option, or the number of shares or amount of property subject to the
         option or, if appropriate, provide for a cash payment to the
         Participant to whom such Option was granted in partial consideration
         for the exchange of the Option.

     (e) Outstanding Options. Other Changes

     In the event of any change in the capitalization of the Company or
     corporate change other than those specifically referred to in Sections
     11(b), (c) or (d) hereof, the Committee may, in its absolute discretion,
     make such adjustments in the number and class of shares subject to Options
     outstanding on the date on which such change occurs and in the per share
     exercise price of each such Option as the Committee may consider
     appropriate to prevent dilution or enlargement of rights.

     (f) No Other Rights

     Except as expressly provided in the Plan, no Participant shall have any
     rights by reason of any subdivision or consolidation of shares of stock of
     any class, the payment of any dividend, any increase or decrease in the
     number of shares of stock of any class or any dissolution, liquidation,
     merger or consolidation of the Company or any other corporation. Except as
     expressly provided in the Plan, no issuance by the Company of shares of
     stock of any class, or securities convertible into shares of stock of any
     class, shall affect, and no adjustment by reason thereof shall be made with
     respect to, the number of shares of Common Stock subject to an Incentive
     Award or the exercise price of any Option.

12.  RIGHTS AS A SHAREHOLDER

   No person shall have any rights as a shareholder with respect to any shares
of Common Stock covered by or relating to any Incentive Award granted pursuant
to this Plan until the date of the issuance of a stock certificate with respect
to such shares. Except as otherwise expressly provided in Section 11 hereof, no
adjustment to any Incentive Award shall be made for dividends or other rights
for which the record date occurs prior to the date such stock certificate is
issued.

13.  NO SPECIAL EMPLOYMENT RIGHTS; NO RIGHT TO INCENTIVE AWARD

   Nothing contained in the Plan or any Incentive Award shall confer upon any
Participant any right with respect to the continuation of his employment by the
Company or interfere in any way with the right of the Company, subject to the
terms of any separate employment agreement to the contrary, at any time to
terminate such employment or to increase or decrease the compensation of the
Participant from the rate in existence at the time of the grant of an Incentive

                                       12
<PAGE>
 
Award.

   No person shall have any claim or right to receive an Incentive Award
hereunder. The Committee's granting of an Incentive Award to a Participant at
any time shall neither require the Committee to grant an Incentive Award to such
Participant or any other Participant or other person at any time nor preclude
the Committee from making subsequent grants to such Participant or any other
Participant or other person.

14.  SECURITIES MATTERS

   (a) The Company shall be under no obligation to effect the registration
   pursuant to the Securities Act of any shares of Common Stock to be issued
   hereunder or to effect similar compliance under any state laws.
   Notwithstanding anything herein to the contrary, the Company shall not be
   obligated to cause to be issued or delivered any certificates evidencing
   shares of Common Stock pursuant to the Plan unless and until the Company is
   advised by its counsel that the issuance and delivery of such certificates is
   in compliance with all applicable laws, regulations of governmental authority
   and the requirements of any securities exchange on which shares of Common
   Stock are traded. The Committee may require, as a condition of the issuance
   and delivery of certificates evidencing shares of Common Stock pursuant to
   the terms hereof, that the recipient of such shares make such covenants,
   agreements and representations, and that such certificates bear such legends,
   as the Committee, in its sole discretion, deems necessary or desirable.

   (b) The exercise of any Option granted hereunder shall only be effective at
   such time as counsel to the Company shall have determined that the issuance
   and delivery of shares of Common Stock pursuant to such exercise is in
   compliance with all applicable laws, regulations of governmental authorities
   and the requirements of any securities exchange on which shares of Common
   Stock are traded. The Company may, in its sole discretion, defer the
   effectiveness of any exercise of an Option granted hereunder in order to
   allow the issuance of shares of Common Stock pursuant thereto to be made
   pursuant to registration or an exemption from registration or other methods
   for compliance available under federal or state securities laws. The Company
   shall inform the Participant in writing of its decision to defer the
   effectiveness of the exercise of an Option granted hereunder. During the
   period that the effectiveness of the exercise of an Option has been deferred,
   the Participant may, by written notice, withdraw such exercise and obtain the
   refund of any amount paid with respect thereto.

15.  WITHHOLDING TAXES

   Whenever shares of Common Stock are to be issued upon the exercise of an
Option, the occurrence of the Issue Date or Vesting Date with respect to a share
of Restricted Stock or the payment of a Stock Bonus, the Company shall have the
right to require the Participant to remit to the Company in cash an amount
sufficient to satisfy federal, state and local withholding tax requirements, if
any, attributable to such exercise, occurrence or payment prior to the delivery
of any certificate or certificates for such shares. In addition, upon the grant
of a Cash Bonus or the making of a payment with respect to a share of Phantom
Stock, the Company shall have the right to withhold from any cash payment
required to be made pursuant thereto an amount sufficient to satisfy the
federal, state and local withholding tax requirements, if any, attributable to
such exercise or grant.

16.  AMENDMENT OF THE PLAN

   The Board of Directors may at any time suspend or discontinue the Plan or
revise or amend it in any respect whatsoever, provided, however, that without
approval of the shareholders no revision or amendment shall (i) except as
provided in Section 11 hereof, increase the number of shares of Common Stock
that may be issued under the Plan, (ii) materially increase the benefits
accruing to individuals holding Incentive Awards granted pursuant to the Plan or
(iii) materially modify the requirements as to eligibility for participation in
the Plan.

17.  NO OBLIGATION TO EXERCISE

   The grant to a Participant of an Option shall impose no obligation upon such
Participant to exercise such Option.

18.  TRANSFERS UPON DEATH

   Upon the death of a Participant, outstanding Incentive Awards granted to such
Participant may be exercised only by the executors or administrators of the
Participant's estate or by any person or persons who shall have acquired such
right to exercise by will or by the laws of descent and distribution. No
transfer by will or the laws of descent and distribution of any Incentive Award,
or the right to exercise any Incentive Award, shall be effective to bind the
Company unless the Committee shall have been furnished with (a) written notice
thereof and with a copy of the will and/or such evidence as the Committee may
deem necessary to establish the validity of the transfer and (b) an agreement by
the transferee to comply with all the terms and conditions of the Incentive
Award that are or would have been applicable to the Participant and to be bound
by the acknowledgments made by the Participant in connection with the grant of
the Incentive Award.

19.  EXPENSES AND RECEIPTS

   The expenses of the Plan shall be paid by the Company. Any proceeds received
by the Company in connection with any Incentive Award will be used for general
corporate purposes.

20.  FAILURE TO COMPLY

   In addition to the remedies of the Company elsewhere provided for herein,
failure by a Participant to comply with any of the terms and conditions of the
Plan or the agreement executed by such Participant evidencing an Incentive
Award, unless such failure is remedied by such Participant within ten days after
having been notified of such failure by the Committee, shall be grounds for the
cancellation and forfeiture of such Incentive Award, in whole or in part as the
Committee, in its absolute discretion, may determine.

21.  EFFECTIVE DATE AND TERM OF PLAN

   The Plan was adopted by the Board of Directors effective November 12, 1997,
subject to approval by the shareholders of the Company in accordance with
applicable law, the requirements of Section 422 of the Code and the requirements
of Rule 16b-3 under Section 16(b) of the Exchange Act. No Incentive Award may be
granted under the Plan after November 11, 2007. Incentive Awards may be granted
under the Plan at any time prior to the receipt of such shareholder approval;
provided, however, that each such grant shall be subject to such approval.
Without limitation on the foregoing, no Option may be exercised prior to the
receipt of such approval, no share certificate shall be issued pursuant to a
grant of Restricted Stock or Stock Bonus prior to the receipt of such approval
and no 

                                       14
<PAGE>
 
Cash Bonus or payment with respect to a share of Phantom Stock shall be paid
prior to the receipt of such approval. If the Plan is not approved by the
Company's shareholders, then the Plan and all Incentive Awards then outstanding
hereunder shall forthwith automatically terminate and be of no force and effect.
 
   IN WITNESS WHEREOF, this 1997 Incentive Stock Plan has been executed in
Houston, Texas this 12th day of November, 1997.

                    PROPOSED OUTSIDE DIRECTORS' OPTION PLAN

     On November 12, 1997, the Board adopted the Outside Directors' Option Plan
(the "Directors' Plan") and proposed the Directors' Plan for the approval of the
Company's stockholders.

     The proposed Directors' Plan provides for the issuance an option to
purchase 15,000 shares per year to each member of the Board of Directors who is
not an employee of the Company. The purpose of the Directors Plan is to
encourage the continued service of outside directors and to provide them with
additional incentive to assist the Company in achieving its growth objectives.
Options may be exercised over a five-year period with the initial right to
exercise, starting one year from the date of the grant, provided the director
has not resigned or been removed for cause by the Board of Directors prior
thereto. After one year from the date of the grant, options outstanding under
the proposed Directors' Plan may be exercised regardless of whether the
individual continues to serve as a director. Options granted under the proposed
Directors' Plan are not transferable except by will or by operation of law. No
options have been granted under the proposed Directors Plan at the date of this
Proxy Statement. If the proposed Directors' Plan is approved by the
stockholders, the total number of shares available for future grant under the
Directors' Plan will be 150,000.

     CONTRACTUAL LIMITATIONS ON OPTION GRANTS. The placement agreement between
the Company, Arizona Securities, Inc. and Paradise Valley Securities, Inc.
limits the total number of options that may be granted during the two years
beginning August 14, 1997 and 1998 to 3% of the total number of shares
outstanding on such dates. Therefore, the maximum number of options that may be
granted under all of the Company's existing and proposed option plans during the
period ended August 15, 1998 will be limited to 854,211 shares, subject to
reduction for any other options that the Board may elect to grant during such
period.

     STOCKHOLDERS ENTITLED TO VOTE AND VOTE REQUIRED FOR APPROVAL. The
affirmative vote of the holders of a majority of all shares of Common Stock
represented and voting at the Meeting, in person or by proxy, will be required
to approve the proposed 1997 Directors' Option Plan. For purposes of determining
the number of votes cast with respect to this proposal, only those cast "for" or
"against" will be included. Abstentions and broker non-votes are counted only
for purposes of determining whether a quorum is present at the meeting.

                                                                   EXHIBIT 10.16

                         EXECUTIVE COMPENSATION PLANS

     The Company has not yet adopted any formal executive compensation plans and
the Board is of the opinion that final decisions respecting the adoption and
implementation of the Company's executive compensation plans should be deferred
pending the appointment of a formal Compensation Committee consisting of two or
more members of the Board, each of whom is a "non-employee director" within the
meaning of SEC Rule 16b-3(b)(3). The Board's decision to defer the adoption and
implementation of executive compensation plans pending the appointment of a
Compensation Committee, however, creates an inherent conflict since Article IV,
Subsection (a) of the Company's Certificate of Incorporation provides in part
that:

   "Notwithstanding the foregoing, and with the sole exception of shares issued
pursuant to those of the Corporation's stock option and other employee benefit
plans which have been approved by the stockholders entitled or required by law
to vote thereon, no shares of Common Stock shall be issued or sold to any
officer or director of the Corporation, or any stockholder who directly or
indirectly owns more than 10% of the issued and outstanding voting stock of the
Corporation, or any affiliate of such a person, without the affirmative vote of
a majority in interest of the disinterested stockholders of the Corporation."

     Since a Compensation Committee cannot be appointed until after the Meeting,
and the Board believes that the prompt adoption and implementation of
appropriate executive compensation plans are essential because achievement of
the Company's long-term business objectives will be dependent in large part upon
the continued efforts, expertise and abilities of the Company's executive
officers, the Board believes that the Stockholders should vote to authorize the
Compensation Committee to develop and implement discretionary executive
compensation plans that may include equity-based incentive awards. If the
Executive Compensation Plan proposal is approved by the stockholders, the
executive officers of the Company will be ineligible to participate in the
proposed 1997 Incentive Stock Plan discussed above and all of the shares
eligible for grant under the 1997 Incentive Stock Plan will be reserved for
issuance to non-executive employees. If the Executive Compensation Plan proposal
is rejected by the stockholders, the executive officers of the Company will be
eligible to participate in the proposed 1997 Incentive Stock Plan and the number
of shares eligible for grant to non-executive employees will be reduced
proportionally.

     If the Executive Compensation Plan proposal is approved by the
stockholders, the Compensation Committee will be granted full power and
authority, without additional stockholder approval, to develop and implement one
or more Executive Compensation Plans that will authorize the Compensation
Committee to grant of incentive equity awards covering a maximum of 1,475,000
shares of Common Stock. It is anticipated that these Executive Compensation
Plans will be similar in most substantive respects to the proposed 1997
Incentive Stock Plan discussed above and that the types of incentive awards
permitted under the Executive Compensation Plans will include (i) non-qualified
stock options, (ii) incentive stock options, (iii) shares of restricted stock,
(iv) shares of phantom stock and (v) stock bonuses. Notwithstanding the
generality of the foregoing, and subject to the requirements of the rules and
regulations of the SEC and applicable Internal Revenue Service Regulations, the
ultimate authority to determine the terms of the Executive Compensation Plans
and the conditions applicable to incentive awards thereunder will be vested
exclusively in the Compensation Committee.

     In addition, if the Executive Compensation Plan proposal is approved by the
stockholders, the Compensation Committee will be granted full power and
authority, without additional stockholder approval, to develop and implement one
or more Acquisition Bonus Plans that will permit the grant of equity awards
covering an indeterminate number of shares of Common Stock in connection with
future acquisitions made by the Company. Subject to the requirements of the
rules and regulations of the SEC and applicable Internal Revenue Service
Regulations, the ultimate authority to determine the terms of such Acquisition
Bonus Plans and the conditions applicable thereto will be vested exclusively in
the Compensation Committee, provided, that the total value of future equity
grants under the Acquisition Bonus Plans may not exceed 5% of the value of
future acquisitions made by the Company.

     CONTRACTUAL LIMITATIONS ON OPTION GRANTS. The placement agreement between
the Company, Arizona Securities, Inc. and Paradise Valley Securities, Inc.
limits the total number of options that may be granted during the two years
beginning August 14, 1997 and 1998 to 3% of the total number of shares
outstanding on such dates. Therefore, the maximum number of options that may be
granted under all of the Company's existing and proposed option plans during the
period ended August 15, 1998 will be limited to 854,211 shares, subject to
reduction for any other options that the Board may elect to grant during such
period.

     STOCKHOLDERS ENTITLED TO VOTE AND VOTE REQUIRED FOR APPROVAL. The
affirmative vote of the holders of a majority of all shares of Common Stock
represented and voting at the Meeting, in person or by proxy, will be required
to authorize the Compensation Committee to develop and implement discretionary
executive compensation plans that may include the issuance of equity-based
incentive awards. For purposes of determining the number of votes cast with
respect to this proposal, only those cast "for" or "against" will be included.
Abstentions and broker non-votes are counted only for purposes of determining
whether a quorum is present at the meeting.

                             SUBLEASE AGREEMENT

        THIS SUBLEASE AGREEMENT ("SUBLEASE") is made and entered into 
effective as of March 1, 1997, between APACHE CORPORATION, a Delaware 
corporation ("SUBLESSOR"), and IWC SERVICES, INC., a Texas corporation 
("SUBLESSEE"):

                                  RECITALS:

        A. Sublessor, as tenant, and Barnhart Interests, Inc., as Agent for
Sage Plaza One Ltd. ("PRIME LESSOR"), as landlord, made and entered into that
certain Lease Agreement (the "PRIME LEASE"), dated as of September 28, 1995,
covering approximately 18,051 square feet of office space (the "PRIME LEASED
PREMISES") in the building located at 5151 San Felipe Road, Houston, Texas,
commonly known as Halliburton Center (the "BUILDING").

        B. Sublessor, as subtenant, and Halliburton Company ("PRIME LESSOR"),
as sublandlord, made and entered into that certain Agreement to Sublease (as
amended, the "PRIME SUBLEASE") dated as of March 15, 1995, and that certain
First Amendment to Agreement to Sublease, covering approximately 64,024 square
feet of office space (the "PRIME SUBLEASED PREMISES") in the Building.

        C. Sublessor has agreed to sublease to Sublessee, and Sublessee has
agreed to sublease and take from Sublessor, a portion of the Prime Leased
Premises and a portion of the Prime Subleased Premises, all located on floor 4
of the Building (the "SUBLEASED PREMISES") and consisting of approximately
6,696 square feet of Net Rentable Area in the aggregate, as depicted by cross-
hatching on the floor plan attached hereto as EXHIBIT A and made a part hereof
for all purposes, on the terms and conditions hereinafter specified.

        1.      DEMISE OF SUBLEASED PREMISES.

                (a)     Subject to and upon the terms and conditions set forth
herein, Sublessor hereby subleases to Sublessee, and Sublessee hereby 
subleases from Sublessor the Subleased Premises. Sublessee acknowledges and 
agrees that it has inspected the subleased Premises and agrees to accept same 
in its present condition, "AS IS" and "WITH ALL FAULTS".

                (b)     SUBLESSEE ACKNOWLEDGES THAT SUBLESSOR HAS NOT MADE AND
WILL NOT MAKE ANY WARRANTIES TO SUBLESSEE WITH RESPECT TO THE QUALITY OF 
CONSTRUCTION OF ANY LEASEHOLD IMPROVEMENTS OR TENANT FINISH WITHIN THE 
SUBLEASED PREMISES OR AS TO THE CONDITION OF THE SUBLEASED PREMISES, EITHER 
EXPRESS OR IMPLIED, AND THAT SUBLESSOR EXPRESSLY DISCLAIMS ANY IMPLIED 
WARRANTY THAT THE SUBLEASED PREMISES ARE OR WILL BE SUITABLE FOR SUBLESSEE'S 
INTENDED COMMERCIAL PURPOSES.



                

<PAGE>
 
                (c)     Any construction of improvements within the Subleased 
Premises desired by Sublessee will be conducted in strict compliance with the 
applicable provisions of the Prime Lease, including, without limitation, 
Article 3 thereof. Upon Sublessee's request received by Sublessor not later 
than June 1, 1997, Sublessor agrees to provide Sublessee an allowance (the 
"CONSTRUCTION ALLOWANCE") in an amount up to $7.00 per square foot of Net 
Rentable Area in the Subleased Premises ($46,872.00) to reimburse Sublessee 
for the costs and expenses of labor and materials incurred from the 
construction and installment of permanent leasehold improvements in the 
Subleased Premises. The Construction Allowance will be funded to Sublessee 
within thirty (30) days following Sublessor's receipt of Sublessee's written 
request therefor, which request will include Sublessee's certification that 
the total costs and expenses paid by Sublessee for the construction and 
installation of permanent leasehold improvements in the Subleased Premises 
were not less than the amount of the Construction Allowance requested by 
Sublessee. If the total costs of the permanent leasehold improvements in the 
Subleased Premises exceed the Construction Allowance, the excess shall be at 
Sublessee's sole cost and expense.

        2.      PREMISE LEASE AND PRIME SUBLEASE.

                (a)     This Sublease is subject and subordinate to the Prime 
Lease and the Prime Sublease, true and correct copies of which have been 
provided to Sublessee. Capitalized terms not otherwise defined in this 
Sublease are used with the meaning assigned to them in the Prime Lease.

                (b)     With the exception of the obligation to pay rentals, 
Sublessee hereby covenants and agrees to comply with and perform all 
obligations of Sublessor under the Prime Lease and the Prime Sublease, insofar
as same pertain and apply to the Subleased Premises, including, without 
limitation, all repair obligations, all insurance obligations, all obligations
to pay utility charges and taxes, and all indemnification obligations of 
Sublessor thereunder, and any liability accruing from failure to pay same when
due thereunder. Sublessee agrees that whenever the consent of Prime Lessor is 
required under the terms of the Prime Lease (or the consent of the Prime 
Sublessor is required under the Prime Sublease) with respect to any action, 
Sublessee shall obtain the consent of Prime Lessor (or Prime Sublessor, as 
applicable) and Sublessor prior to taking such action. Sublessee hereby 
covenants and agrees to promptly deliver to Sublessor copies of any and all 
notices or other correspondence received by Sublessee from Prime Lessor or 
Prime Sublessor that might affect Sublessor in any manner and further agrees, 
notwithstanding Section 13 hereof to the contrary, to so deliver same in the 
manner most appropriate to insure that Sublessor will be able to respond to 
any of such notices or other correspondence from the Prime Lessor or Prime 
Sublessor within any time periods set forth in the Prime Lease or the Prime 
Sublease, as applicable.

                (c)     Sublessor covenants and agrees that except for the 
obligations assumed by Sublessee under Section 1(b) above, Sublessor will duly
and faithfully perform each of its obligations, duties and liabilities under 
the Prime Lease and the Prime Sublease. Sublessor covenants and agrees that it
will not enter into any amendment to the Prime Lease or the Prime Sublease that
would adversely effect Sublessee's use and enjoyment of the Subleased 
Premises.

                                     -2-
<PAGE>
 
                (d)     Sublessee acknowledges and agrees that the only 
services, amenities and rights to which Sublessee is entitled under this 
Sublease are those to which Sublessor is entitled under the Prime Lease or the
Prime Sublease, as applicable (subject to all the provisions, restrictions and
conditions imposed of the Prime Lease or the Prime sublease, as applicable, 
and only to the extent that same apply directly to Subleased Premises). 
Sublessor shall in no event be liable to Sublessee for Prime Lessor's or Prime
Sublessor's failure to provide any such services, amenities and rights. 
Sublessee agrees that no such failure by Prime Lessor or Prime Sublessor shall
be construed as a breach hereof by Sublessor or an eviction of Sublessee or 
entitle Sublessee to an abatement of any of the rentals under this Sublease, 
except and only to the extent that Sublessor receives an abatement under the 
Prime Lease or Prime Sublease, as applicable, with respect thereto.

                (e)     Sublessee shall not have the right to exercise any of 
Sublessor's options or elections permitted or authorized under the Prime Lease
of the Prime Sublease, or to institute any action or proceeding against Prime 
Lessor or Prime Sublessor for the enforcement of the Prime Lease or the Prime 
Sublease. If Prime Lessor or Prime Sublessor shall default in the performance 
of any of its obligations under the Prime Lease or the Prime Sublease, as
applicable, Sublessor shall, upon the written request of Sublessee and at 
Sublessee's sole cost and expense, use its diligent good faith efforts to 
enforce its remedies under the Prime Lease or the Prime Sublease, as 
applicable, to cause Prime Lessor or Prime Sublessor to comply with its 
obligations thereunder.

        3.      TERM

                (a)     Unless the Prime Lease or Prime Sublease is 
terminated sooner pursuant to the terms thereof, the term of this Sublease 
("TERM") shall be for the period commencing on March 22, 1997 (the 
"COMMENCEMENT DATE") and ending on August 31, 2003. Any occupancy of the 
Subleased Premises by Sublessee prior to the Commencement Date shall be 
subject to all of the terms and conditions of this Sublease other than the 
obligation to pay rentals.

                (b)     At the termination of this Sublease or of Sublessee's 
right to possession of the Subleased Premises, by lapse of time or otherwise, 
Sublessee shall deliver up the subleased Premises to Sublessor in as good 
condition as existed on the date of possession by Sublessee, ordinary wear and
tear only excepted. Upon such termination of this Sublease or of Sublessee's 
right to possession of the Subleased Premises, Sublessor shall have the right 
to re-enter and resume possession of the Subleased Premises.

                (c)     In the event of holding over by Sublessee after 
expiration or termination of this Sublease without the prior written consent 
of Sublessor, Sublessee shall as liquidated damages and amount equal to one 
and one-half (1-1/2) the amount of all base rental and additional rental that 
was payable by Sublessee immediately prior to such expiration or termination, 
pro rated on a daily basis for the entire holdover period. In the event of any
unauthorized holding over, Sublessee shall also indemnify Sublessor against 
all claims for damages (i) by any other tenant to whom Sublessor may have 
subleased all or any part of the Subleased Premises effective upon the 

                                     -3-

<PAGE>
 
termination of this Sublease, (ii) by Prime Lessor for default by Sublessor 
under the Prime Lease, and (iii) by Prime Sublessor for default by Sublessor 
under the Prime Sublease. Any such holding over without the prior written 
consent of Sublessor shall create a tenancy at sufferance relationship with 
Sublessee.

        4.      RENT

                (a)      Sublessee hereby agrees to pay an annual base rental 
to Sublessor with respect to the Subleased Premises as follows:


                                  Annual Base Rental
                                Per Square Foot of Net    Monthly Base
Time Period                        Rentable Area        Rental Payments
- -----------                     ----------------------  ---------------
March 22, 1997 - 
        September 30, 1997               $15.11            $8,431.38
October 1, 1997 -
        February 28, 1998                $13.28            $7,410.24    
March 1, 1998 -
        August 31, 2003                  $11.21            $6,255.18

Sublessee shall pay such base rental to Sublessor in equal monthly 
installments without demand, for each and every month during the Term, on the 
first day of each month beginning on the Commencement Date.

                (b)     Beginning in 1998 and for each year thereafter during 
the Sublease term, Sublessee will pay to Sublessor as additional rental its 
proportionate share (defined below) of the amount, if any, by which (i) the 
Basic Cost payable by Sublessor under the Prime Lease for each such year 
exceeds the amount of the Basic Cost payable by Sublessor under the Prime Lease
for the year 1997, and (ii) the Basic Cost payable by Sublessor under the 
Prime Sublease for each such year exceeds the amount of the Basic Cost payable
by Sublessor under the Prime Sublease for the year 1997. Sublessee's 
proportionate share of Basic Cost will be payable monthly beginning January 
1998 based on the estimates of Basic Cost provided by Prime Lessor under 
Sections 5.04 and 5.05 of the Prime Lease and the estimates provided to 
Sublessor by Prime Sublessor under the corresponding provisions of the Prime 
Sublease. If any adjustment is made thereafter to Sublessor's payments with 
respect to Basic Cost under Sections 5.06 or 5.07 of the Prime Lease and/or 
under the corresponding provisions of the Prime Sublease, Sublessee will pay 
or receive, as the case may be, a corresponding adjustment of its payments 
with respect to Basic Cost under this Section 4(b).

                (c)     Each monthly installment of base rental and additional
rental due to Sublessor under this Sublease shall be payable by Sublessee on 
the first day of each calendar month at Sublessor's address herein set forth 
or at such other place as Sublessor shall designate in writing from time to 
time. If less than all of any calendar month or year occurs during the Term, 
rents for



                                     -4-
<PAGE>
 
such partial month or year shall be prorated based on the actual number of 
days during such month or year occurring within the Term.

                (d)     As used in this Section 4, Sublessee's "proportionate 
share" means:

                (i)     as to the portion of the Subleased Premises that is 
part of the Prime Leased Premises, the percentage determined by (x) dividing 
the Net Rentable Area of that portion of the Subleased Premises by the Net 
Rentable Area of the Prime Leased Premises, and (y) multiplying the 
quotient obtained in clause 4(d)(i)(x) by 100; and

                (ii)    as to the portion of the Subleased Premises that is 
part of the Prime Subleased Premises, the percentage determined by (x) 
dividing the Net Rentable Area of that portion of the Subleased Premises by 
the Net Rentable Area of the Prime Subleased Premises, and (y) multiplying the
quotient obtained in clause 4(d)(ii)(x) by 100.

        5.      SECURITY DEPOSIT. On the date of execution of this Sublease by
Sublessee, there shall be due and payable by Sublessee a security deposit in 
the amount of $7,929.00, such deposit to be held for the performance by 
Sublessee of Sublessee's covenants and obligations under this Sublease, it 
being expressly understood that the deposit shall not be considered an advance
payment of rental or a measure of Sublessor's damages in case of default by 
Sublessee. Upon the occurrence of any event of default by Sublessee or breach 
by Sublessee of Sublessee's covenants or obligations under this Sublease, 
Sublessor may, from time to time, without prejudice to any other remedy, use 
the security deposit to the extent necessary to make good any arrears of 
rental or other payments hereunder and/or any damage, injury, expense or 
liability caused to Sublessor by such event or breach of covenant. Following 
any such application of the security deposit, sublessee shall pay to Sublessor
on demand the amount so applied in order to restore the security deposit to 
the amount thereof existing prior to such application. Any remaining balance 
of the security deposit shall be returned by Sublessor to Sublessee within 
thirty (30) days after the termination of this Sublease; provided, however, 
Sublessor shall have the right to retain and expend such remaining balance (a)
to reimburse Sublessor for any and all rentals or other sums due hereunder 
that have not been paid in full by Sublessee and/or (b) for cleaning and 
repairing the Subleased Premises if Sublessee shall fail to deliver same at 
the termination of this Sublease in a neat and clean condition and in as good 
a condition as existed at the date of possession of same by Sublessee, 
ordinary wear and tear only excepted. Sublessee shall not be entitled to any 
interest on the security deposit.

        6.      USE. The Subleased Premises will be used for general office 
purposes only, and Sublessee will use and maintain the Subleased Premises in a
lawful manner consistent with the standards of operation of the Building and 
the other tenants thereof.

        7.      PARKING. Sublessee will be entitled to the use of 15 parking 
permits in the Building Parking Garage throughout the Term at no additional 
cost, all of which will be for unreserved/unassigned parking. Sublessee 
acknowledges that Sublessor's rights to such parking spaces arise under the 
Prime Sublease and are accordingly subject to the terms of that sublease.

        8.      ASSIGNMENT AND SUBLETTING

                (a)     Sublessee shall not, without the prior written consent
of Sublessor, assign, transfer, mortgage, pledge, hypothecate or encumber this
Sublease or any interest herein or sublet the Subleased Premises or any part 
thereof, or permit the use of the Subleased Premises by any party other than 
Sublessee. Any such assignment or subletting without such consent by Sublessor
shall be void. Any such consent by Sublessor to any such assignment or 
subletting shall not release Sublessee from any of Sublessee's obligations 
hereunder to be deemed to be a consent to any subsequent assignment, 
subletting, occupation or use by another person.

                (b)     Sublessor's consent to any proposed assignment or 
subleting will not be unreasonably withheld, provided that notwithstanding 
Sublessor's consent the proposed assignment of subletting will be subject to 
the further consent of Prime Lessor and Prime Sublessor (provided that in the 
case of a subletting, Prime Lessor's consent will be required only if 
Sublessor's rights to any portion of the Subleased Premises being sublet are 
derived under the Prime Lease, and Prime Sublessor's consent will be required 
only if Sublessor's rights to any portion of the Subleased Premises being 
sublet are derived under the Prime Sublease). Sublessee agrees that reasonable
bases upon which Sublessor may decide whether to consent to the proposed 
assignment or subletting include (but are not limited to) the criteria 
enumerated in Section 13.02 of the Prime Lease.

        9.      INDEMNITIES

                (a)     Sublessor shall indemnify Sublessee and Prime Lessor 
for and hold Sublessee harmless from and against all costs, expenses 
(including reasonable attorney's fees), fines, suits, claims, demands, 
liabilities and actions resulting from any breach, violation or nonperformance
of any covenant or condition hereof or from any negligent act or omission of 
Sublessor or Sublessor's employees, agents or contractors, except to the 
extent that any such costs, expenses, fines, suits, claims, demands, 
liabilities and actions which are also attributable to the negligence of 
Sublessee, its employees, agents or contractors.

                (b)     Sublessee shall indemnify Sublessor and Prime Lessor 
for and hold Sublessor and Prime Lessor harmless from and against all costs, 
expenses (including reasonable attorneys' fees), fines, suits, claims, 
demands, liabilities and actions resulting from any breach, violation or 
nonperformance of any covenant or condition hereof, from any liens imposed for
non-payment of any mechanics or materialmens in connection with any tenant 
improvements to the subleased premises, or from any negligent act or omission 
of Sublessee or Sublessee's employees, agents and contractors, except to the 
extent that any such costs, expenses, fines, suits, claims,

                                     -6-

<PAGE>
 
demands, liabilities and actions which are also attributable to the negligence
of Sublessor, its employees, agents or contractors.

        10.     DEFAULT BY SUBLESSEE: REMEDIES OF SUBLESSOR.  In case of any 
breach hereof by Sublessee, in addition to all other rights of Sublessor 
hereunder or available to Sublessor at law or equity, Sublessor shall have all
the rights against Sublessee as would be available to the Prime Lessor against
Sublessor under the Prime Lease if such breach were by Sublessor thereunder.

        11.     QUIET ENJOYMENT.  Provided Sublessee has performed all of the 
terms, covenants, agreements and conditions of this Sublease, including the 
payment of rental and all other sums due hereunder, Sublessee shall peaceably 
and quietly hold and enjoy the Subleased Premises against Sublessor and all 
persons claiming by, through or under Sublessor, for the term herein 
described, subject to the provisions and conditions of this Sublease, the 
Prime Lease and the Prime Sublease.

        12.     LIMITATION OF SUBLESSOR'S LIABILITY.

                (a)     It is understood and agreed that the provisions of 
Section 11 above and any and all other covenants of Sublessor contained in 
this Sublease shall be binding upon Sublessor and its successors only with 
respect to breaches occurring during its and their respective ownership of the
Sublessor's interest hereunder. This Sublease is subject to and subordinate to
all matters of public record in Harris, Texas.

                (b)     Sublessor shall not be liable to Sublessee or 
Sublessee's employees, agents, contractors, licensees or invitees for any 
damage to person or property resulting from any act or omission of any visitor
to the Subleased Premises except as Sublessor's own negligence may contribute 
thereto.

        13.     NOTICES.  All notices, consents, requests, instructions,

                             SUBLEASE AGREEMENT

        THE SUBLEASE AGREEMENT is made and entered into on this 31st day of 
December, 1997 by and between ITS SUPPLY CORPORATION, a corporation organized 
and existing under the laws of the State of Delaware (hereinafter referred to 
as "Sublessee"), and International Tool & Supply Company, Inc., a corporation 
organized and existing under the laws of the State of Delaware (hereinafter 
referred to as "Sublessor").
        
                                 WITNESSETH:

        WHEREAS, Sublessor is the Lessee under a Lease Contract (the "Lease") 
entered into by and between Camac Holdings, Inc., as Lessor ("Camac") and 
Sublessor, which Lease includes 10,454 square feet of Rentable Area located on
the fourth floor of the building currently known as "Camac Plaza", located at 
4669 Southwest Freeway, Houston, Texas; and

        WHEREAS, Sublessee desires to sublease 10,454 square feet of Rentable 
Area located on the fourth floor of Camac Plaza and 238 square feet of 
Rentable Area currently used for storage located on the first floor of Camac 
Plaza (collectively, the "Sublease Area") from Sublessor pursuant to and 
subject to the terms and conditions hereinafter set forth;

        NOW THEREFORE, in consideration of the mutual covenants and promises 
set forth below, the parties hereto do hereby agree as follows:

1.      Sublessor hereby subleases to Sublessee and Sublessee hereby subleases
        from Sublessor the Sublease Area pursuant to and subject to the terms
        and conditions hereinafter set forth. The Sublease Area is subleased
        "as is" and neither Sublessor nor Camac (or its successors or assigns)
        shall have any obligation to make improvements thereto.

2.      This Sublease shall become effective on January 1, 1998 and, except as
        otherwise provided herein, shall continue in full force until the 30th
        day of June 1999. Notwithstanding the foregoing, however, Sublessee
        shall have the right to terminate this Sublease Agreement, and the
        sublease thereunder, at any time by giving no less than twelve (12)
        months written notice of its intent to so terminate prior to such
        termination.

3.      Sublessee agrees to pay without demand a rental rate of $9,028.00 per
        month for the Sublease Area located on the fourth floor and $236.00
        per month for the Sublease Area located on the first floor. Such
        rental rate shall be due and payable on the first day of each calendar
        month, and Sublessee hereby agrees to pay such rent monthly in advance
        without demand to Sublessor at Sublessor's address as may be
        designated from time to time by Sublessor.

4.      Sublessor agrees that there shall be no escalation in the rental rate 
        to be paid by Sublessee during the term of this Sublease.




<PAGE>
 
5.      Except as expressly otherwise provided herein, Sublessee agrees to be
        bound by all of the terms and conditions of the Lease (including Exhibit
        "D"thereto), a copy of which is attached hereto, as if Sublessee were
        the Lessee thereunder and Sublessor were the Lessor thereunder.
