          CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS

  This document contains "forward-looking statements" within the meaning of
the Private Securities Litigation Reform Act of 1995. These statements are
subject to risks and uncertainties and are based on the beliefs and
assumptions of management, based on information currently available to
management. Forward-looking statements can be identified by the use of the
future tense or other forward-looking words such as "believe," "expect,"
"anticipate," "intend," "plan," "estimate," "should," "may," "will,"
"objective," "projection," "forecast," "management believes," "continue,"
"strategy," "position" or the negative of those terms or other variations of
them or by comparable terminology. In particular, statements, express or
implied, concerning future operating results or the ability to generate sales,
income or cash flow are forward-looking statements. Forward-looking statements
include the information concerning possible or assumed future results of
operations of the Company set forth under:

  .  Item 1, Business

  .  Item 7, Management's Discussion and Analysis of Financial Condition and
     Results of Operations

  .  Item 7A, Quantitative and Qualitative Disclosures about Market Risk.

  Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. The future results and shareholder value
of the Company may differ materially from those expressed in these forward-
looking statements. Many of the factors that will determine these results and
values are beyond management's ability to control or predict. These statements
are necessarily based upon various assumptions involving judgments with
respect to the future including, among others,

  .  the ability to achieve synergies and revenue growth,

  .  national, regional and local economic, competitive and regulatory
     conditions and developments,

  .  technological developments,

  .  capital market conditions,

  .  inflation rates,

  .  interest rates,

  .  weather conditions,

  .  the timing and success of business development efforts, and

  .  other uncertainties,

all of which are difficult to predict and many of which are beyond
management's control. Shareholders are cautioned not to put undue reliance on
any forward-looking statements.

  Shareholders should understand that the foregoing important factors, in
addition to those discussed elsewhere in this document, could affect the
future results of the Company and could cause results to differ materially
from those expressed in such forward-looking statements.

                                    PART I

Item 1. Description of Business.

  Encompass Services Corporation ("Encompass"), a Texas corporation
incorporated in 1997, is the leading nationwide provider of facilities
services to commercial, industrial and residential customers. Its operations
are conducted through subsidiaries operating in approximately 250 locations
throughout the United States. As used herein, the "Company" refers to
Encompass and its subsidiaries.

Merger With Building One Services Corporation

  In November 1999, Group Maintenance America Corp. ("GroupMAC"), the
predecessor of Encompass, and Building One Services Corporation ("Building
One") entered into an Agreement and Plan of Merger providing for the merger of
Building One with and into GroupMAC (the "Merger"). The Merger was completed
in February 2000 to form Encompass Services Corporation. As a result of the
Merger, the combined company is approximately twice the size of each of
GroupMAC and Building One and has the capability of providing mechanical,
electrical and janitorial services, either alone or in combination with
another service, in more locations than either constituent company could
perform on its own. For additional information concerning the Merger, see Item
7, "Management's Discussion and Analysis of Financial Condition and Results of
Operations," and Note 18 to the Consolidated Financial Statements of Encompass
Services Corporation and Subsidiaries.

  Because the Merger occurred in February 2000, the financial statements
included herein do not reflect the historical operations of Building One.
Furthermore, because the Merger will be accounted for as a reverse acquisition
of GroupMAC by Building One, financial statements for future periods will
reflect the historical operations of Building One rather than GroupMAC.

  In connection with the Merger, Encompass issued to an affiliate of Apollo
Management, L.P. approximately $256 million of 7.25% Convertible Preferred
Stock in exchange for $150 million in cash and approximately $106 million
aggregate principal amount of Building One convertible subordinated
debentures. Based upon the current conversion price of $14.00 per share, the
preferred stock is convertible into approximately 18.2 million shares of
Encompass common stock, representing approximately 23% of the voting power of
Encompass. Encompass used the cash proceeds from the issuance of the
Convertible Preferred Stock to permit its shareholders to convert
approximately 11.1 million shares of Encompass common stock into cash pursuant
to the Merger.

Other Developments in 1999

  During 1999, the Company acquired 14 mechanical and electrical services
companies with combined annual revenues of approximately $406 million. These
acquisitions resulted in an increase in the portion of the Company's business
derived from commercial and industrial customers as the Company focused its
acquisition program on companies that could further the implementation of the
Company's national accounts initiatives. The Company significantly expanded
its electrical and communications business with the acquisition of five
electrical service companies. With these acquisitions and the addition of the
Building One operating companies, the Company comprises approximately 250
locations in 38 states and has $3.6 billion in pro forma 1999 revenues. The
Company's expanded geographic coverage and service mix will allow it to pursue
business opportunities that were not previously available and lessen its
dependence on acquisitions to fulfill its business plan.

  The Company intends to selectively make additional acquisitions of
businesses offering mechanical, electrical/communications and janitorial
services within the commercial, industrial and residential markets. The
Company's long term objective is to be able to offer each of these services in
the 100 largest metropolitan areas in the United States.

</TABLE>

  Upon the consummation of the Merger with Building One, the
Commercial/Industrial Group was reorganized into four groups--the Mechanical
Group, the Electrical/Communications Group, the Industrial Group and the
National Accounts Group.

Services Provided

  Mechanical. The Company designs, installs, maintains, repairs and replaces
the heating, ventilating and air conditioning ("HVAC"), control and monitoring
and process piping systems in commercial and industrial facilities such as
manufacturing and processing facilities, power generation facilities,
hospitals and other critical care facilities, colleges and universities,
hotels, commercial office buildings, retail stores, and restaurants,
supermarkets, and convenience stores. The services provided include both
maintenance, repair and replacement ("MRR") services and new installation
services for products such as compressor-bearing HVAC equipment, boilers,
chillers, central plants, process piping and control systems. The MRR work
includes preventive maintenance (periodic checkups, cleaning and filter
change-outs), emergency repairs and the replacement (in conjunction with the
retrofitting or remodeling of a commercial building, or as a result of an
emergency request) of HVAC systems and associated parts, plumbing fixtures,
pipes, water feed and sewer lines, water heaters, softeners, filters and
controls. The Commercial/Industrial Group also designs and installs
mechanical, electrical and other systems on behalf of owners or general
contractors in commercial buildings.

  Electrical/Communications. The Company installs, maintains and upgrades the
electrical systems of commercial/industrial facilities, including process
controls, lighting, power, lifesafety systems and energy management systems.
The Company also designs, installs, upgrades, maintains and repairs low energy
systems ("LES") including voice and data cabling, high speed data network
infrastructure systems, fiber optics, video, security and sound. LES is the
fastest growing segment of the electrical construction business. Additionally,
through its information technology unit, Total Site SolutionsSM, the Company
provides consulting services, turnkey design and installation work for various
mission critical facilities such as telecommunications facilities, call
centers, network control rooms, mainframe data centers, trading floors,
laboratories and medical facilities, which must remain on line 100% of the
time. Total Site SolutionsSM also provides broad-based service agreements that
include provision and administration of bundled preventive maintenance and
emergency response services for these facilities.

                                       3
<PAGE>

Customers

  The Company's commercial/industrial customers include general contractors,
facility owners, facility managers, developers, utilities, energy service
companies, property managers, engineers, consultants, and architects. The
Company expects to perform an increasing amount of services for energy service
companies seeking to bundle their service and commodity product offerings.

  The Company is seeking to expand the services it provides to building owners
and operators through a national accounts marketing effort focusing on
entities that are responsible for operating the mechanical and electrical
systems of buildings located throughout the United States. The Company's
customers include Microsoft, Lincoln Properties, Pep Boys, Blockbuster and MCI
Worldcom. No customer accounts for more than 2% of the Commercial/Industrial
Group's revenues.

                               RESIDENTIAL GROUP

  Through its Residential Group, the Company provides mechanical and other
contracting services to homebuilders and homeowners from 38 locations.
Although most of the Group's locations perform MRR services, five of the
operating companies emphasize new construction work and represent 69% of the
Group's revenues.

  The following table shows the revenue mix of the Residential Group for each
of the fiscal years ended December 31, 1999 and 1998:

Services

  The Residential Group installs HVAC and plumbing systems in homes, apartment
and condominium complexes and small commercial buildings. It also provides
maintenance services for these systems, such as inspections, cleaning, repair
and replacement of HVAC systems and associated parts; repair and replacement
of bathroom fixtures, water filters and water heaters; and cleaning, repair
and replacement of pipes, sewer lines and residential sanitary systems. In
connection with its maintenance, repair and replacement services, the Company
sells a wide range of HVAC, plumbing and other equipment, including complete
HVAC systems and a variety of parts and components.

Customers

  The Company markets its residential new installation contracting services to
local, regional and national homebuilders, including U.S. Home Corporation,
Pulte Home Corporation, Centex Corporation, and Beazer Homes Corporation. The
Company targets its growth in the residential new installation market in those
areas of the United States that have growth rates above the national average.
Through strong existing relationships with major national homebuilders, the
Company is marketing its capabilities to provide consistent, reliable
installation services on a regional basis. No customer accounts for more than
3% of the Residential Group's revenues.

  The Company's customers for residential maintenance, repair and replacement
services consist primarily of homeowners. The Company advertises its
maintenance and repair services in the yellow pages, on billboards, on
television and radio, and through direct mail. It also relies upon unique
service offerings to attract and retain customers.

                               JANITORIAL GROUP

  The Janitorial Group, which was acquired by the Company in February 2000 in
connection with the Building One merger, offers janitorial and maintenance
management services in 50 states. The Company believes that the Janitorial
Group is the largest provider of janitorial and maintenance management
services to the retail sector in the United States based on revenues.

Services

  The services provided by the Janitorial Group include:

  .floor and carpet cleaning and maintenance;

  .floor stripping and refinishing;

  .chemical supply and equipment management;

  .window, wall and structural cleaning and maintenance;

  .restroom and other area sanitation;

  .duct cleaning;

  .furniture polishing; and

  .exterior window, wall, sidewalk, and parking lot cleaning and maintenance.

  If requested by a customer, the Janitorial Group selects, manages and
integrates services provided by its operating companies and third parties to
customers and often administers the back office functions for the third party
to ensure the quality of the service performed. The Janitorial Group also
relieves its customers from the burden of finding and supervising the
contractor or in-house labor to provide service.

Customers

  The customers of the Janitorial Group include retail chain stores, grocery
stores, office buildings, industrial plants, banks, department stores,
warehouses, educational and health facilities, restaurants, and airport
terminals throughout the United States. The Company often provides services to
a customer under a contractual arrangement on a regional or national basis.
The Janitorial Group's customers include MCI Worldcom, Walmart, Safeway, UPS,
Trammell Crow and CB Richard Ellis. No single customer accounts for more than
8% of the Janitorial Group's revenues.

                                  OPERATIONS

  In providing maintenance, repair and replacement services, the Company uses
specialized systems to log service orders, schedule service calls, identify
and ready the necessary parts and equipment, track the work order, provide
information for communication with the service technicians and customers, and
prepare accurate invoices. Service histories and specific product information
are generally accessible to the dispatcher in a database that may be searched
by customer name or address. Maintenance, repair and replacement calls are
initiated when a customer requests emergency repair service or the Company
calls the client to schedule periodic service agreement maintenance. Service
technicians are scheduled for the call or routed to the customer's business or
residence by the dispatcher via a scheduling board or daily work sheet (for
non-emergency service) or through cellular telephone, pager or radio. Service
personnel work out of the Company's service vehicles, which carry an inventory
of equipment, tools, parts and supplies needed to complete the typical variety
of jobs. The technician assigned to a service call travels to the business or
residence, interviews the customer, diagnoses the problem, presents the
solution, obtains agreement from the customer and performs the work.

  A portion of the Company's service work is done to satisfy manufacturers'
equipment warranties. For such services, the Company is generally compensated
by the manufacturer responsible for the defective equipment under warranty.
The Company attempts to enter into service contracts whereby the customer pays
an annual or semiannual fee for periodic diagnostic and preventive services.
The customers under service contracts receive priority service and specific
discounts from standard prices for repair and replacement services.

  Commercial new installation work begins with a design request from the owner
or general contractor. Initial meetings with the parties allow the contractor
to prepare preliminary and then more detailed design specifications,
engineering drawings and cost estimates. Once a project is awarded, it is
conducted in pre-agreed phases and progress billings are rendered to the owner
for payment, less a retainage. Actual field work (ordering of equipment and
materials, fabrication or assembly of certain components, delivery of
materials to the job sites, scheduling of work crews with the necessary
skills, and inspection and quality control) is coordinated in these same
phases. The Company has established a policy to review and approve any new
installation project by an operating unit that exceeds 5% of the projected
annual revenue of that unit.

  The Company will generally perform work contracted by it using its personnel
who work from one of the Commercial/Industrial Group's 68 locations. However,
the Company may subcontract with other contractors to perform work in
locations where the Company does not have a facility or where the Company's
backlog requires additional resources.

  Residential service technicians may carry a Customer Assurance Pricing
manual developed by the Company which specifies the labor, equipment and parts
required to fulfill certain tasks and the associated flat rate prices for
those tasks. This manual is custom generated for each company from a database
containing over 15,000 different repair operations and is regularly updated
for price changes. This "flat rate pricing" strategy allows the Company to
monitor margins and labor productivity at the point of sale, while increasing
the level of customer satisfaction by demonstrating greater fairness and
objectivity in pricing. Payment for maintenance, repair and replacement
services not covered by a warranty or service contract is generally requested
in cash, check or credit card at the service location.

  The Janitorial Group assigns regional contract managers to each customer.
The contract managers determine whether to self perform work or utilize the
group's existing network of 425 cleaning companies to subcontract duties. Each
of the group's three major divisions (retail, commercial and industrial) use
the subcontractor network whenever possible because of the proven benefits
(reliability, quality consistency and customer preference) of using the local
workforce. The Janitorial Group's Quality Measurement System measures the
quality of cleaning and customer support efforts. In addition, the group runs
a 24/7 call center to handle any emergency cleaning requests and has a
national computer network to respond quickly and appropriately to any customer
requests.

Sources of Supply

  The raw materials and components used by the Company include HVAC system
components, ductwork, steel sheet metal and copper tubing and piping. These
raw materials and components are generally available from

                                       6
<PAGE>

a variety of domestic or foreign suppliers at competitive prices. Delivery
times are typically short for most raw materials and standard components, but
during periods of peak demand, may extend to a month or more. Chillers for
large units typically have the longest delivery time and generally have lead
times of up to three to four months. The major components of HVAC systems are
condensing units and chillers that are manufactured primarily by Trane Air
Conditioning Company, Carrier Corporation, and York Heating and Air
Conditioning Company. The major suppliers of control systems are Honeywell
Inc., Johnson Controls, Inc. and Andover Control Corporation. The Company is
not materially dependent on any of these outside sources.

Employees

  The Company currently has approximately 30,000 full and part-time employees.
In the course of performing installation work, the Company may utilize the
services of subcontractors. Approximately 3,800 employees (in 20 of the
Company's subsidiaries) are members of unions and work under collective
bargaining agreements. The collective bargaining agreements have expiration
dates between April 2000 and June, 2007. The Company believes that its
relationship with its employees is generally satisfactory.

Seasonality

  The Company's mechanical and electrical services business tends to be
affected adversely by moderate weather patterns. Comparatively warm winters
and cool summers reduce the demand for its maintenance, repair and replacement
services. Additionally, its new installation business is affected adversely by
extremely cold weather and large amounts of rain. As a result, the Company
expects that its revenues and operating results will be lower in the first
and, to a lesser degree, fourth calendar quarters. Prolonged weather
conditions or seasonal variations may cause unpredictable fluctuations in
operating results.

Backlog

  At December 31, 1999 and 1998, the Company's backlog of work was
approximately $589.7 million and $420.7 million, respectively. Of the December
31, 1999 backlog, approximately $543.6 million related to the Company's
commercial/industrial operations and the remaining $46.1 million related to
the Company's residential operations. The Company expects that during 2000 it
will complete a substantial portion of the backlog as of December 31, 1999.

Competition

  The facility services industry is highly competitive. The Company believes
that the principal competitive factors in the facility services industry are
(i) timeliness, reliability and quality of services provided, (ii) range of
services offered, (iii) market share and visibility and (iv) price. The
Company believes its strategy of creating a leading national provider of
comprehensive services directly addresses these factors. The ability of the
Company to employ, train and retain highly motivated service technicians to
provide quality services should be enhanced by its ability to utilize
professionally managed recruiting and training programs. In addition, the
Company expects to offer compensation, health and savings benefits that are
more comprehensive than most offered in the industry. Competitive pricing is
possible through purchasing economies and other cost saving opportunities that
exist across each of the service lines offered and from productivity
improvements.

  Most of the Company's competitors are small, owner-operated companies that
typically operate in a single market. Certain of these smaller competitors may
have lower overhead cost structures and may be able to provide their services
at lower rates. Moreover, many homeowners have traditionally relied on
individual persons or small repair service firms with whom they have long-
established relationships for a variety of home repairs. There are currently a
limited number of public companies focused on providing services in some of
the same service lines provided by the Company.

  In addition, there are a number of national retail chains that sell a
variety of plumbing fixtures and equipment and HVAC equipment for residential
use and offer, either directly or through various subcontractors,
installation, warranty and repair services. Other companies or trade groups
engage in franchising their names and marketing programs in some service
lines. In addition, HVAC equipment manufacturers, the unregulated business
segments of regulated gas and electric utilities and deregulated utilities are
entering into various

                                       7
<PAGE>

commercial/industrial or residential service areas. Certain of the Company's
competitors and potential competitors have greater financial resources than
the Company to finance acquisition and development opportunities, to pay
higher prices for the same opportunities or to develop and support their own
commercial/industrial or residential service operations if they decide to
enter the field.

Governmental Regulation

  Many aspects of the Company's operations are subject to various federal,
state and local laws and regulations, including, among others, (1) permitting
and licensing requirements applicable to contractors in their respective
trades, (2) building, mechanical and electrical codes and zoning ordinances,
(3) laws and regulations relating to consumer protection, including laws and
regulations governing service contracts for residential services, and (4) laws
and regulations relating to worker safety and protection of human health. In
Florida, warranties provided for in the Company's service agreements subject
the Company and such agreements to some aspects of that state's insurance laws
and regulations. Specifically, the Company is required to maintain funds on
deposit with the Florida Office of Insurance Commissioner and Treasurer, the
amount of which is not material to the Company's business. The Company is in
compliance with these deposit requirements.

  The Company believes it has all required permits and licenses to conduct its
operations and is in substantial compliance with applicable regulatory
requirements relating to its operations. Failure of the Company to comply with
the applicable regulations could result in substantial fines or revocation of
the Company's operating permits.

  A large number of state and local regulations governing the residential
services trades require various permits and licenses to be held by
individuals. In some cases, a required permit or license held by a single
individual may be sufficient to authorize specified activities for all the
Company's service technicians who work in the geographic area covered by the
permit or licenses.

Environmental Regulation

  The Company's operations are subject to numerous federal, state and local
environmental laws and regulations, including those governing the remediation
of contaminated soil and groundwater, vehicle emissions and the use and
handling of refrigerants. These laws and regulations are administered by the
United States Environmental Protection Agency, the Coast Guard, the Department
of Transportation and various state and local governmental agencies. The
technical requirements of these laws and regulations are becoming increasingly
complex and stringent, and meeting these requirements can be expensive. The
nature of the Company's operations and its ownership or operation of property
expose it to the risk of claims with respect to such matters, and there can be
no assurance that material costs or liabilities will not be incurred in
connection with such claims. Federal and state environmental laws include
statutes intended to allocate the cost of remedying contamination among
specifically identified parties. For example, the federal Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA" or
"Superfund") can impose strict, joint and several liability on past and
present owners or operators of facilities at, from or to which a release of
hazardous substances has occurred, on parties who generated hazardous
substances that were released at such facilities and on parties who arranged
for the transportation of hazardous substances to such facilities. A majority
of states have adopted "Superfund" statutes comparable to, and in some cases
more stringent than, CERCLA. If the Company were to be found to be a
responsible party under CERCLA or a similar state statute, the Company could
be held liable for all investigative and remedial costs associated with
addressing such contamination, even though the releases were caused by a prior
owner or operator or third party. In addition, claims alleging personal injury
or property damage may be brought against the Company as a result of alleged
exposure to hazardous substances resulting from the Company's operations.

  Prior to entering into the agreements relating to the acquisition of
businesses, the Company evaluated the properties owned or leased by those
businesses and in some cases engaged an independent environmental consulting
firm to conduct or review assessments of environmental conditions at certain
of those properties. No material environmental problems were discovered in
these reviews, and the Company is not otherwise aware of

                                       8
<PAGE>

any actual or potential environmental liabilities that would be material to
the Company. There can be no assurance that all such liabilities have been
identified, that such liabilities will not occur in the future, that a party
could not assert a material claim against the Company with respect to such
liabilities, or that the Company would be required or able to answer for such
claim.

  The Company's operations are subject to the Clean Air Act, Title VI of which
governs air emissions and imposes specific requirements on the use and
handling of substances known or suspected to cause or contribute significantly
to harmful effects on the stratospherical ozone layer, such as
chlorofluorocarbons and certain other refrigerants ("CFCs"). Clean Air Act
regulations require the certification of service technicians involved in the
service or repair of systems, equipment and appliances containing these
refrigerants and also regulate the containment and recycling of these
refrigerants. These requirements have increased the Company's training
expenses and expenditures for containment and recycling equipment. The Clean
Air Act is intended ultimately to eliminate the use of CFCs in the United
States and require alternative refrigerants to be used in replacement HVAC
systems. The implementation of the Clean Air Act restrictions has also
increased the cost of CFCs in recent years and is expected to continue to
increase such costs in the future. As a result, the number of conversions of
existing HVAC systems that use CFCs to systems using alternative refrigerants
is expected to increase.

  The Company's operations in certain geographic regions are subject to laws
that will, over the next few years, require specified percentages of vehicles
in large vehicle fleets to use "alternative" fuels, such as compressed natural
gas or propane, and meet reduced emissions standards. The Company does not
anticipate that the cost of fleet conversion that may be required under
current laws will be material. Future costs of compliance with these laws will
be dependent upon the number of vehicles purchased in the future for use in
the covered geographic regions, as well as the number and size of future
business acquisitions by the Company in these regions. The Company cannot
determine to what extent its future operations and earnings may be affected by
new regulations or changes in existing regulations relating to vehicle
emissions.

  Capital expenditures related to environmental matters during the fiscal year
ended December 31, 1999, were not material. The Company does not currently
anticipate any material adverse effect on its business or consolidated
financial position as a result of future compliance with existing
environmental laws and regulations controlling the discharge of materials into
the environment. Future events, however, such as changes in existing laws and
regulations or their interpretation, more vigorous enforcement policies of
regulatory agencies or stricter or different interpretations of existing laws
and regulations may require additional expenditures by the Company which may
be material.

Item 2. Properties.

  The Company's executive offices are located in leased office space at 3
Greenway Plaza, Suite 2000, Houston, Texas 77046.

  The Company's vehicle fleet is estimated to be approximately 9,500 owned or
leased service trucks, vans and support vehicles. It believes these vehicles
generally are well-maintained, ordinary wear and tear excepted, and adequate
for the Company's current operations.

  The Company conducts its business from approximately 250 facilities,
substantially all of which are leased under agreements with remaining terms up
to 11 years from the date hereof on terms the Company believes to be
commercially reasonable. A majority of the Company's facilities are leased
from certain former shareholders (or entities controlled by certain former
shareholders) of its subsidiaries. The provisions of the leases are on terms
the Company believes to be at least as favorable to the Company as could have
been negotiated by the Company with unaffiliated third parties. The Company
believes the owned and leased facilities are adequate to serve its current
level of operations.

                                       9
<PAGE>

  The Company believes that it has generally satisfactory title to the
property owned by it, subject to the liens for current taxes, liens incident
to minor encumbrances and easements and restrictions that do not materially
detract from the value of such property or the interests therein or the use of
such property in its business. Additionally, the inventory and accounts
receivable of the Company and the capital stock of its subsidiaries are
subject to a lien under its credit facility.

Item 3. Legal Proceedings.

  The Company is a party to various legal proceedings. It is not possible to
predict the outcome of these matters. However, in the opinion of management,
the resolution of these matters will not have a material adverse effect on the
Company's financial condition or results of operations.

Item 4. Submission of Matters to a Vote of Security Holders.

  The Company did not submit any matter to a vote of its security holders
during the fourth quarter of 1999.

Item 4A. Executive Officers.

  The following table sets forth certain information concerning the executive
officers of the Company as of March 1, 2000:

Dividends

  Under applicable corporate law, the Company may pay dividends out of surplus
(as defined under the Texas Business Corporation Act). At December 31, 1999,
the Company had surplus of approximately $426.0 million for the payment of
dividends. The Company has not paid a dividend on the Common Stock since its
incorporation and does not anticipate paying any dividends on the Common Stock
in the foreseeable future because it intends to retain any earnings to finance
the expansion of its business, to repay indebtedness and for general corporate
purposes. Under the terms of the Company's 7.25% Convertible Preferred Stock,
the holders of the Convertible Preferred Stock are entitled to receive in the
aggregate dividends of approximately $18.6 million per year, payable
quarterly. However, the Company has the option, until March 2003, of deferring
the payment of dividends on the Convertible Preferred Stock without any
adverse consequences other than a compounding of the dividends payable in the
future. The Company has elected to defer the payment of the dividend that
would otherwise be payable on March 31, 2000.

  Any payment of future dividends will be at the discretion of the Board of
Directors and will depend upon, among other things, the Company's earnings,
financial condition, capital requirements, level of indebtedness, contractual
restrictions with respect to the payment of dividends and other relevant
factors. Additionally, the Company's revolving credit facility prohibits the
payment of dividends without the consent of the lenders, the Company's
indenture relating to the 10 1/2% Senior Subordinated Notes due 2009 assumed
in connection with the Merger (the "10 1/2% Notes") places restrictions on the
ability of the Company to pay dividends other than dividends on its
Convertible Preferred Stock, and the holders of the Convertible Preferred
Stock must approve payment of dividends on the Common Stock in excess of five
percent of the value of the Common Stock during any twelve month period. For
additional information concerning the Company's revolving credit facility and
the 10 1/2% Notes, see Note 7 and Note 18, respectively, to the Consolidated
Financial Statements included under Item 8 of this Annual Report.

Item 6. Selected Financial Data.

  Our first acquisition was that of Airtron. For accounting purposes, this
transaction was accounted for as a reverse acquisition, as if Airtron acquired
Encompass, because the former shareholders of Airtron owned a majority of our
common stock upon consummation of the acquisition. As such, the Selected
Income Statement and Balance Sheet data set forth below as of and for the two-
year period ended February 28, 1997 have been derived from the audited
financial statements of Airtron. The financial statements of Encompass and its
subsidiaries, other than Airtron, are included in the financial statements
from their respective dates of acquisition.

  The selected financial data presented below should be read in conjunction
with Item 7, "Management's Discussion and Analysis of Financial Condition and
Results of Operations," and Item 8, "Financial Statements and Supplementary

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations.

  Encompass Services Corporation ("Encompass"), formerly Group Maintenance
America Corp. ("GroupMAC"or the "Company") was incorporated to build a
national company providing mechanical and electrical services in the
commercial, industrial and residential markets. The following review of the
Company's financial condition and results of operations should be read in
connection with the consolidated financial statements and related notes
presented in Item 8.

Merger With Building One Services Corporation

  On February 22, 2000, the shareholders of both GroupMAC and Building One
Services Corporation ("Building One") approved a merger of the two companies
(the "Merger"). Under the terms of the Merger, each outstanding share of
Building One common stock was converted into 1.25 shares of GroupMAC common
stock. In addition, approximately 11,052,000 shares of GroupMAC common stock
were converted into cash at a rate of $13.50 per share pursuant to a cash
election right available to GroupMAC shareholders. In connection with the
closing of the Merger, GroupMAC amended its articles of incorporation to
change the Company's name to Encompass Services Corporation.

  Concurrent with the closing of the Merger, an affiliate of Apollo
Management, L.P. exchanged $106 million of Building One convertible junior
subordinated debentures and $150 million of cash for approximately $256
million of GroupMAC convertible preferred stock. The preferred stock will
mature in 2012, will bear a dividend yield coupon rate of 7.25% and will be
convertible into shares of GroupMAC common stock at a conversion price of $14
per common share. The proceeds from the issuance of the convertible preferred
stock were used to fund the cash election feature of the Merger.

  On February 22, 2000, GroupMAC entered into a new credit agreement to
provide a total of $800 million in financing. The proceeds of this new credit
agreement were used to refinance the existing revolving credit facilities of
GroupMAC and Building One, as well as GroupMAC's senior subordinated notes. In
addition, GroupMAC assumed the 10 1/2% Senior Subordinated Notes due 2009 of
Building One.

  GroupMAC was the surviving legal entity in the Merger. However, for
accounting purposes, Building One is deemed to be the acquiror and,
accordingly, the Merger will be accounted for as a "reverse acquisition."
Under this method of accounting, Encompass' historical results for periods
prior to the Merger will be the same as Building One's historical results.

General

  The Company has historically derived revenues from providing maintenance,
repair and replacement and new installation services for mechanical,
electrical and other systems to commercial/industrial and residential
customers. Revenues for 1999 consisted of the following (dollars in
thousands):

<TABLE>

                                                          ----------    -----
  Total.................................................. $1,547,791    100.0%
                                                          ==========    =====
</TABLE>

  The Company recognizes maintenance, repair and replacement revenues as the
services are performed, except for service contract revenue, which is
recognized ratably over the life of the contract. The Company generally
accounts for revenues from fixed price installation and retrofit contracts on
a percentage-of-completion basis, using the cost-to-cost method.

  Cost of services consists primarily of components, parts and supplies
related to new installation and maintenance, repair and replacement services,
salaries and benefits of service and installation technicians, subcontracted
services, depreciation, fuel and other vehicle expenses and equipment rentals.
Selling, general and

                                      15
<PAGE>

administrative expenses consist primarily of compensation and related benefits
for management, administrative salaries and benefits, advertising, office rent
and utilities, communications and professional fees.

  The Company's balanced business mix is reflected to varying degrees in its
gross margins. The gross margin for the businesses providing services to
commercial/industrial markets was 18.7% for the twelve months ended December
31, 1999. The Company's businesses performing primarily maintenance, repair
and replacement services in the residential markets tend to have higher gross
margins, averaging 32.3% for the twelve months ended December 31, 1999. On
average, the Company's residential new installation businesses have lower
gross margins. Such companies' gross margin was 23.0% for the twelve months
ended December 31, 1999. Future consolidated gross margins may vary depending
on, among other things, shifts in the business mix as well as the impact of
future acquisitions on the business mix.

  The Company has realized savings from (1) greater volume discounts from
suppliers of components, parts and supplies; (2) consolidation of insurance
and bonding programs; (3) other general and administrative expenses such as
training and advertising; and (4) its ability to borrow at lower interest
rates than most, if not all, of its subsidiaries. These savings are offset by
costs related to corporate management structure, costs associated with being a
public company and integration costs.

  Effective April 30, 1997, the Company entered into an Agreement and Plan of
Exchange with Airtron (the "Airtron Agreement"), pursuant to which the Company
issued $20.4 million in cash, 14.9 million shares of preferred stock and 4.7
million shares of common stock to shareholders of Airtron in exchange for all
of the then outstanding shares of Airtron. Although for legal purposes Airtron
was acquired by the Company, for accounting purposes the transaction was
accounted for as a reverse acquisition, as if Airtron acquired the Company,
due to the fact that the former shareholders of Airtron then owned a majority
of the outstanding common stock. In connection with the reverse acquisition,
the Company recorded the consideration paid to the shareholders of the Company
as non-recurring compensation expense of $7.0 million in the accompanying
consolidated statements of operations for the ten months ended December 31,
1997. The consolidated financial statements included elsewhere herein for the
periods prior to the effective date of the acquisition only include the
accounts of Airtron. The consolidated statements of shareholders' equity have
been converted from Airtron's capital structure to the Company's capital
structure to reflect the exchange of shares pursuant to the Airtron Agreement.
Concurrent with the initial public offering of the Company's common stock in
November 1997 (the "IPO"), the Company changed its fiscal year end from
February 28 to December 31.

  As of December 31, 1999, the Company was comprised of 73 operating companies
performing services in 64 cities across 28 states. Through its acquisitions
since the IPO, the Company has increased the portion of its business derived
from commercial/industrial customers and focused its acquisition program on
companies that could further the implementation of the Company's national
accounts initiatives. The Company has also significantly expanded its
electrical and data cabling business through these acquisitions.

Twelve Months Ended December 31, 1999 Compared To Twelve Months Ended December
31, 1998

  Revenues. Revenues increased $786.3 million, or 103.2%, to $1,547.8 million
for the twelve months ended December 31, 1999 from $761.5 million for the
twelve months ended December 31, 1998. The increase in revenues is
attributable to the following:

  . $624.7 million relates to the incremental revenue contributed in the
    twelve months ended December 31, 1999 by commercial/industrial companies
    acquired during or subsequent to the twelve months ended December 31,
    1998;

  . $13.1 million relates to the incremental revenue contributed in the
    twelve months ended December 31, 1999 by residential companies acquired
    during or subsequent to the twelve months ended December 31, 1998;

  . $117.0 million relates to the same store growth in the
    commercial/industrial group. Of this increase, $47.2 million results from
    growth in work in mission-critical environments and voice/data cabling in
    the Mid-Atlantic region and $25.0 million relates to volume increases in
    the Seattle/Portland market, with the balance of the increase generated
    primarily from the Dallas, Little Rock, Toledo, Minneapolis, Bakersfield,
    California and Vail, Colorado markets; and

  . $31.5 million relates to the same store growth in the residential group.
    Of this increase, $22.9 million relates to companies that primarily
    provide new installation services due to an increase in new home starts
    in the markets they serve and $8.6 million relates to companies that
    primarily provide maintenance, repair and replacement services.

  Gross Profit. Gross profit increased $142.6 million, or 80.9%, to $318.7
million for the twelve months ended December 31, 1999 from $176.1 million for
the twelve months ended December 31, 1998. The increase in gross profit is
attributable to the following:

  . $117.1 million relates to the incremental gross profit contributed in the
    twelve months ended December 31, 1999 by commercial/industrial companies
    acquired during or subsequent to the twelve months ended December 31,
    1998;

                                      17
<PAGE>

  . $2.4 million relates to the incremental gross profit contributed in the
    twelve months ended December 31, 1999 by residential companies acquired
    during or subsequent to the twelve months ended December 31, 1998;

  . $13.8 million relates to the same store growth in the
    commercial/industrial group. Of this increase, $5.1 million results from
    growth in work in mission-critical environments and voice/data cabling in
    the Mid-Atlantic region and $4.3 million relates to volume increases in
    the Seattle/Portland market, with the balance of the increase generated
    primarily from the Little Rock, Toledo, Minneapolis and Vail, Colorado
    markets. Partially offsetting these increases were continued economic
    softening in the Richmond, Virginia market and general labor
    inefficiencies caused by the shortage of experienced field personnel in
    the industry and additional overtime hours incurred to handle the
    substantial volume of work, which had the most impact on the Dallas
    market;

  . $7.7 million relates to the same store growth in the residential group.
    Of this increase, $5.2 million relates to companies that primarily
    provide new installation services due to an increase in new home starts
    in the markets they serve and $2.5 million relates to companies that
    primarily provide maintenance, repair and replacement services; and

  . $1.6 million relates to additional materials purchases savings in the
    current period.

  Gross profit margin decreased 2.5% for the twelve months ended December 31,
1999 compared to the twelve months ended December 31, 1998 because of the
Company's acquisition emphasis during 1998 and 1999 on commercial/industrial
businesses, which support the Company's national accounts initiatives. These
businesses typically have lower gross margins than residential businesses.
Also impacting the decrease were gross profit declines in the Dallas and
Richmond, Virginia markets, as well as the general labor inefficiencies
referred to above.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses, including goodwill amortization and merger and
related charges, increased $90.6 million, or 73.1%, to $214.7 million for the
twelve months ended December 31, 1999 from $124.1 million for the twelve
months ended December 31, 1998. The increase in these expenses is attributable
to the following:

  . $59.6 million relates to the incremental selling, general and
    administrative expenses incurred in the twelve months ended December 31,
    1999 by commercial/industrial companies acquired during or subsequent to
    the twelve months ended December 31, 1998;

  . $1.5 million relates to the incremental selling, general and
    administrative expenses incurred in the twelve months ended December 31,
    1999 by residential companies acquired during or subsequent to the twelve
    months ended December 31, 1998;

  . $12.3 million relates to the same store growth in the
    commercial/industrial group, with $1.7 million of the increase coming
    from the Mid-Atlantic market and $3.8 million from the Company's
    Seattle/Portland operations;

  . $5.4 million relates to the same store growth in the residential group;

  . $7.1 million relates to incremental corporate expenses representing
    expansion of the corporate management team, expenses of employee benefit
    programs and infrastructure necessary to execute the Company's operating
    and acquisition strategies;

  . $3.7 million relates to non-recurring, non-deductible charges related to
    costs incurred in connection with the Merger (see above discussion and
    Note 18 to the Consolidated Financial Statements);

  . $6.6 million relates to an increase in goodwill amortization associated
    with the above described acquisitions.

  Partially offsetting the above increases is approximately $5.3 million of
increased savings related to the Company's property and casualty insurance
programs and a $0.3 million decrease in field bonuses.

                                      18
<PAGE>

  As a percentage of revenues, selling, general and administrative expenses,
excluding corporate expenses, non-recurring charges related to the Merger and
goodwill amortization, decreased to 11.8% for the twelve months ended December
31, 1999 from 14.0% for the twelve months ended December 31, 1998, due
primarily to achieving lower selling, general and administrative expense
margins on a same store basis and acquiring a higher mix of commercial
companies which tend to have lower selling, general and administrative expense
structures relative to revenues earned. When including corporate expenses and
goodwill amortization but excluding non-recurring charges related to the
Merger, selling, general and administrative expenses as a percentage of
revenues decreased to 13.6% for the twelve months ended December 31, 1999 from
16.2% for the twelve months ended December 31, 1998.

  Net Interest. Net interest increased $22.5 million during the twelve months
ended December 31, 1999 compared to the same period of the prior year. Such
increase was attributable to a higher level of borrowings under the Company's
credit facility and the issuance in January 1999 of $130 million in Senior
Subordinated Notes, which carried a higher rate of interest than loans under
the credit facility. The higher level of borrowings was needed to finance the
Company's aggressive acquisition program during 1998 and 1999. See "Liquidity
and Capital Resources."

  Income Tax Provision. The income tax provision increased $14.2 million to
$34.5 million for the twelve months ended December 31, 1999 from $20.3 million
for the twelve months ended December 31, 1998. This increase corresponds with
the pre-tax income increase of $29.8 million between periods. The effective
tax rate for the twelve months ended December 31, 1999 was 45.3% compared to
43.9% for the twelve months ended December 31, 1998. The effective tax rate
exceeds the Company's statutory federal and state tax rate and has increased
between years due primarily to non-deductible goodwill amortization of $9.3
million and non-deductible merger and related charges of $3.7 million in 1999
compared to $6.0 million of non-deductible goodwill amortization in 1998. When
excluding the non-deductible merger and related charges in 1999, the overall
effective tax rate decreased to 43.2% in 1999 from 43.9% in 1998. This overall
decrease in the effective tax rate results from certain income tax strategies,
including structuring seven of the Company's acquisitions as taxable asset
acquisitions, resulting in the deductibility of goodwill for these entities.

Twelve Months Ended December 31, 1998 Compared To Ten Months Ended December
31, 1997

  Revenues. Revenues increased $623.0 million, or 450.0%, to $761.5 million
for the twelve months ended December 31, 1998 from $138.5 million for the ten
months ended December 31, 1997. The increase in revenues is attributable to
the following:

  . $328.7 million relates to 28 commercial/industrial companies acquired
    during 1998,

  . $54.1 million relates to 11 residential companies acquired during 1998,

  . $186.7 million relates to 13 companies acquired simultaneous with the
    IPO, resulting in twelve months of revenues during 1998 compared to two
    months of revenues during 1997,

  . $29.3 million relates to the other 10 companies acquired in June and July
    of 1997, resulting in twelve months of revenue during 1998 compared to
    six or seven months of revenues during 1997, and

  . $24.2 million relates to Airtron, resulting in twelve months of revenues
    in 1998 compared to ten months of revenues in 1997.

  Gross Profit. Gross profit increased $139.4 million, or 379.8%, to $176.1
million for the twelve months ended December 31, 1998 from $36.7 million for
the ten months ended December 31, 1997. The increase in gross profit is
attributable to the following:

  . $66.0 million relates to 28 commercial/industrial companies acquired
    during 1998,

  . $15.2 million relates to 11 residential companies acquired during 1998,

                                      19
<PAGE>

  . $37.2 million relates to 13 companies acquired simultaneous with the IPO,
    resulting in twelve months of activity during 1998 compared to two months
    of activity during 1997,

  . $8.9 million relates to the other 10 companies acquired in June and July
    of 1997, resulting in twelve months of activity during 1998 compared to
    six or seven months of activity during 1997,

  . $10.1 million relates to Airtron, resulting in twelve months of activity
    in 1998 compared to ten months of activity in 1997, and

  . $2.0 million relates to materials purchases savings.

  Gross profit margin decreased 3.4% for the twelve months ended December 31,
1998 compared to the ten months ended December 31, 1997 because of the
Company's 1998 acquisition emphasis on com-mercial/industrial businesses,
which support the Company's national accounts initiatives although they
typically have lower gross margins than residential businesses.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $87.6 million, or 240.0%, to $124.1 million
for the twelve months ended December 31, 1998 from $36.5 million for the ten
months ended December 31, 1997. The increase in selling, general and
administrative expenses is attributable to the following:

  . $37.5 million relates to 28 commercial/industrial companies acquired
    during 1998,

  . $10.6 million relates to 11 residential companies acquired during 1998,

  . $23.5 million relates to 13 companies acquired simultaneous with the IPO,
    resulting in twelve months of activity during 1998 compared to two months
    of activity during 1997,

  . $6.5 million relates to the other 10 companies acquired in June and July
    of 1997, resulting in twelve months of activity during 1998 compared to
    six or seven months of activity during 1997,

  . $4.3 million relates to Airtron, resulting in twelve months of activity
    in 1998 compared to ten months of activity in 1997,

  . $7.8 million relates to corporate expenses representing the formation of
    the corporate management team and infrastructure necessary to execute the
    Company's operating and acquisition strategies,

  . $5.3 million relates to goodwill amortization associated with the above
    described acquisitions, and

  . $2.6 million relates to field bonuses.

  Offsetting the above increases were the following reductions:

  . $7.0 million reduction in compensation expense recognized in the prior
    year from the reverse acquisition of Airtron, and

  . $3.5 million of savings related to the Company's property and casualty
    insurance programs.

  As a percentage of revenues, selling, general and administrative expenses,
excluding corporate expenses, goodwill amortization and the 1997 non-recurring
compensation expense, decreased to 14.0% for the twelve months ended December
31, 1998 from 18.3% for the ten months ended December 31, 1997. This decrease
was due primarily to achieving lower selling and administrative expense
margins within the 23 companies acquired during 1997 and acquiring a higher
mix of commercial/industrial companies which tend to have lower selling and
administrative expense structures relative to revenues earned. When including
corporate expenses and goodwill amortization, but excluding the non-recurring,
non-cash compensation expense of $7.0 million, selling, general and
administrative expenses as a percentage of revenue decreased to 16.2% for the
twelve months ended December 31, 1998 from 21.1% for the ten months ended
December 31, 1997.

                                      20
<PAGE>

  Net Interest. Net interest increased $5.0 million during the twelve months
ended December 31, 1998 compared to the ten months ended December 31, 1997 due
to borrowings under our credit facility to fund our aggressive acquisition
program during 1998. See "Liquidity and Capital Resources."

  Income Tax Provision. The income tax provision increased $17.5 million, or
625.0%, to $20.3 million for the twelve months ended December 31, 1998 from
$2.8 million for the ten months ended December 31, 1997. This increase
corresponds with the pre-tax income increase of $40.1 million between periods
after adding back the $7.0 million of non-recurring, non-cash compensation
expense related to the reverse acquisition of Airtron. The effective tax rate
for the twelve months ended December 31, 1998 was 43.9% compared to 45.8% for
the ten months ended December 31, 1997 after adding back the $7.0 million of
non-recurring, non-cash compensation expense related to the reverse
acquisition of Airtron. The decrease results primarily from income tax
planning strategies implemented during 1998.

Year 2000

  The Year 2000 issue refers to the inability of certain date sensitive
computer chips, software and systems to recognize a two-digit date field as
belonging to the 21st century. Many computer software programs, as well as
certain hardware and equipment containing date sensitive data, were structured
to utilize a two-digit date field. Accordingly, these programs may not be able
to properly recognize dates in the year 2000 and later, which could result in
significant system and equipment failures.

  The Company has completed its Year 2000 plan to address the issues resulting
from the Year 2000. To date the Company has encountered no major automation or
business disruptions due to Year 2000 issues. The Company continues to operate
normally through all of its operating companies and will continue to monitor
operations throughout 2000.

  The Company is monitoring the effect of the Year 2000 on its most
significant customers and suppliers, and thus indirectly on the Company. To
date, none of these significant customers and suppliers has encountered
business interruptions due to the Year 2000 that have impacted the Company's
operations. There are no individual customers who will have a material impact
on our revenues should they fail to complete their Year 2000 efforts.
Additionally, the Company has alternative vendors that can be relied on should
a current vendor fail in its Year 2000 preparations.

  Independent of its Year 2000 activities discussed in the previous
paragraphs, the Company has been developing a common information system
throughout the organization for its overall information needs that would be
free of any Year 2000 limitations. The Company's board of directors previously
approved the prototype and pilot phase of an enterprise resource planning
("ERP") system. This phase commenced in July 1999 and was expected to take
approximately ten months to complete, with conclusion originally expected by
the end of the second quarter of the Year 2000. The Merger required that
management focus all resources towards the integration of the Building One
companies. Accordingly, implementation of the ERP system has been suspended
until such time as the information needs of the Building One companies can be
assessed and factored into the overall systems strategy of the combined
organization. To date, the Company has expended approximately $6.1 million
related to the implementation of the ERP system.

Seasonality and Cyclicality

  The HVAC industry is subject to seasonal variations. Specifically, the
demand for new installations is generally lower during the winter months due
to reduced construction activities during inclement weather and less use of
air conditioning during the colder months. Demand for HVAC services is
generally higher in the second and third quarters. Accordingly, the Company
expects its revenues and operating results generally will be lower in the
first and, to a lesser degree, fourth quarters. Historically, the construction
industry has been highly cyclical. As a result, the Company's volume of
business may be adversely affected by declines in new installation projects in
various geographic regions of the United States.

                                      21
<PAGE>

  A substantial portion of the Company's business involves installation of
mechanical and electrical systems in newly constructed residences and
commercial/industrial facilities. Our revenues from new installation services
in the residential market is dependent upon the level of housing starts in the
areas in which we operate. The housing industry is cyclical, and the Company's
revenues from residential new installation will be affected by the factors
that affect the housing industry. These factors include changes in employment
and income levels, the availability and cost of financing for new home buyers
and general economic conditions. The level of new commercial/industrial
installation services is also affected by changes in economic conditions and
interest rates. General downturns in housing starts or new
commercial/industrial construction in the areas in which the Company operates
could have a material adverse effect on its business, including its financial
condition and results of operations.

Inflation

  Inflation did not have a significant effect on the results of operations for
the years ended December 31, 1999 and 1998, or the ten months ended December
31, 1997.

Liquidity and Capital Resources

  Historically, the Company has financed its operations and growth with
internally generated working capital and borrowings from commercial banks or
other lenders. These borrowings (other than subordinated debt) are secured by
the Company's accounts receivable and inventory.

  At December 31, 1999, the Company had outstanding $249.4 million of
borrowings under its then existing $425 million revolving credit facility (the
"Credit Agreement"). In connection with the Merger with Building One, the
Company entered into a new $800 million revolving credit facility and borrowed
funds under the new facility to repay (i) the borrowings under the old
facility, (ii) $130 million of senior subordinated notes (the "Senior
Subordinated Notes") issued in January 1999, and (iii) borrowings of Building
One under its revolving credit facility. As of March 27, 2000, $743.5 million
of borrowings were outstanding under the new facility. The availability of
borrowings under the new facility is subject to the Company's ability at the
time to meet certain specified conditions, which the Company believes it
currently meets. These conditions include compliance with the financial
covenants and ratios required by the new credit facility, absence of default
under the facility and continued accuracy of the representations and
warranties contained in the facility (including the absence of any material
adverse changes since the specified dates). Also in connection with the
Merger, the Company assumed the 10 1/2% Senior Subordinated Notes due 2009 of
Building One.

  Concurrent with the closing of the Merger, an affiliate of Apollo
Management, L.P. exchanged $106 million of Building One convertible junior
subordinated debentures and $150 million of cash for approximately $256
million of Encompass convertible preferred stock. The preferred stock will
mature in 2012, will bear a dividend yield coupon rate of 7.25% and will be
convertible into shares of Encompass common stock at a conversion price of $14
per common share. The proceeds from the issuance of the convertible preferred
stock were used to fund the cash election feature of the Merger.

  The Company's largest need for capital in the past has been to fund
acquisitions. Historically, the Company has generally paid for its
acquisitions with cash and common stock in approximately equal amounts. The
Company intends to continue to use its common stock as a significant component
of the consideration that it pays for businesses to be acquired. When the
Company's common stock price declines, the Company generally reduces the price
it is willing to pay for acquisitions and in some cases may increase the cash
component of the purchase price. If the price of the Company's common stock
declines, then the Company believes that the number of companies willing to be
acquired at an accretive price may be reduced, which could adversely impact
the growth of the Company. Furthermore, if the Company pays a greater
proportion of the consideration of future acquisitions in cash, then it will
exhaust its available credit faster than would otherwise be the case and would
increase its ratio of debt to total capitalization.

  The Company's primary requirements for capital (other than those related to
acquisitions) consist of purchasing vehicles, inventory and supplies used in
the operation of the business. During the years ended

                                      22
<PAGE>

December 31, 1999 and 1998 and the ten months ended December 31, 1997, capital
expenditures aggregated $20.1 million, $9.3 million and $2.0 million,
respectively. The Company anticipates that its cash flow from operations and
existing credit facilities will provide cash in excess of its normal working
capital needs, debt service requirements and planned capital expenditures for
property and equipment.

  For the years ended December 31, 1999 and 1998 and the ten months ended
December 31, 1997, the Company generated $29.6 million, $0.9 million and $4.4
million of cash from operating activities, respectively. For the year ended
December 31, 1999, net income, depreciation, amortization, deferred taxes and
other items generated $72.6 million and changes in asset and liability
accounts utilized a net $43.0 million. The use of cash due to changes in asset
and liability accounts is due primarily to increased levels of receivables,
the majority of which results from internal revenue growth during the twelve
months ended December 31, 1999. For the year ended December 31, 1998, net
income, depreciation, amortization, deferred taxes and non-cash compensation
generated $43.5 million and changes in asset and liability accounts utilized a
net $42.6 million. For the ten months ended December 31, 1997, net loss,
depreciation, amortization, deferred taxes and non-cash compensation generated
$7.5 million and changes in asset and liability accounts utilized a net $3.1
million.

  For the year ended December 31, 1999, the Company used $137.1 million of
cash in investing activities. These activities principally consisted of $116.0
million for acquisitions and $20.1 million for capital expenditures. For the
year ended December 31, 1998, the Company used $189.2 million in investing
activities. These activities principally consisted of $178.5 million for
acquisitions and $9.3 million for capital expenditures. For the ten months
ended December 31, 1997, the Company used $37.9 million in investing
activities. These activities principally consisted of $35.8 million for
acquisitions and $2.0 million for capital expenditures.

  For the year ended December 31, 1999, the Company generated $108.6 million
of cash from financing activities. These activities principally consisted of
proceeds from long-term debt, net of offering costs, of $357.1 million and
$248.8 million in payments of long-term debt. For the year ended December 31,
1998, the Company generated $165.0 million in cash from its financing
activities. These activities principally consisted of proceeds from long-term
debt of $884.5 million and payments of long-term debt of $719.5 million. For
the ten months ended December 31, 1997, the Company generated $54.9 million in
cash from its financing activities. These activities principally consisted of
issuance of common stock for $109.7 million and proceeds from long-term debt
of $32.5 million less distributions to shareholders of $20.4 million, payments
of long-term debt of $47.7 million and retirement of preferred stock of $19.3
million.

  The Company intends to selectively pursue strategic acquisition
opportunities. Management believes that funds provided by operations, together
with funds available under the Company's new credit facility entered into with
Bank of America, N.A. and Chase Bank of Texas, N.A. (as Co-Lead Arrangers and
Co-Book Managers) in connection with the Merger and other financing sources
will be adequate to meet its anticipated requirements for acquisitions.
Estimates as to working capital needs and other expenditures may be materially
affected if the foregoing sources are not available or do not otherwise
provide sufficient funds to meet the Company's obligations.

New Accounting Pronouncements

  In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." This
statement establishes new accounting and reporting standards requiring that
all derivative instruments (including certain derivative instruments embedded
in other contracts) be recorded in the balance sheet as either an asset or
liability measured at its fair value. The statement requires that changes in
the derivative's fair value be recognized currently in earnings unless
specific hedge accounting criteria are met. Special accounting for qualifying
hedges allows a derivative's gains and losses to offset related results on the
hedged item in the income statement and requires that a company must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting. This statement, as amended, is effective for all fiscal
years beginning after June 15, 2000. Under present operations, this statement
will have no impact on the Company's financial position or results of
operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

  The table below provides information about the Company's market sensitive
financial instruments as of December 31, 1999 and 1998. In connection with the
Merger, the Company has refinanced the borrowings under the Credit Agreement
and the Senior Subordinated Notes with proceeds from a new $800 million
revolving credit facility discussed in Item 7 and has assumed $200 million of
Building One's 10.5% Senior Subordinated Notes. The Company's major market
risk exposure is changing interest rates. All items described are non-trading
and are stated in U.S. dollars (in thousands). The information constitutes a
"forward looking statement."

(a) The Credit Agreement borrowings bore interest at a rate per annum, at the
    Company's option, of either (1) the Alternate Base Rate or (2) the
    Eurodollar Rate. The Alternate Base Rate is equal to the greater of the
    Federal Funds Effective Rate plus 0.5% or the Prime Rate plus a Margin
    depending on the ratio of indebtedness for borrowed money to EBITDA (with
    all capitalized terms as defined in the Credit Agreement). The Eurodollar
    Rate is the rate defined in the Credit Agreement plus a Margin depending
    on the ratio of indebtedness for borrowed money to EBITDA. At December 31,
    1999 and 1998, the weighted average interest rates in effect for the
    Credit Agreement borrowings were 8.34% and 7.08%, respectively.
(b) The Senior Subordinated Notes were unsecured, matured in January 2009 and
    bore interest at 9.75% payable semi-annually. In addition, there were
    approximately $11.0 million in related debt issuance costs which were
    being amortized to interest expense over the ten year life of these notes,
    increasing the effective interest rate to 10.6%.

                         INDEPENDENT AUDITORS' REPORT

The Board of Directors
Encompass Services Corporation:

  We have audited the accompanying consolidated balance sheets of Encompass
Services Corporation (formerly Group Maintenance America Corp.) and
Subsidiaries as of December 31, 1999 and 1998 and the related consolidated
statements of operations, shareholders' equity and cash flows for the years
ended December 31, 1999 and 1998, and the ten months ended December 31, 1997.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Encompass
Services Corporation (formerly Group Maintenance America Corp.) and
Subsidiaries as of December 31, 1999 and 1998 and the results of their
operations and their cash flows for the years ended December 31, 1999 and 1998
and the ten months ended December 31, 1997, in conformity with generally
accepted accounting principles.

1. BUSINESS AND ORGANIZATION

  Encompass Services Corporation ("Encompass"), formerly Group Maintenance
America Corp. ("GroupMAC" or "the Company" ) was incorporated as a Texas
corporation to build a national company providing mechanical and electrical
services in the commercial, industrial and residential markets.

  Effective April 30, 1997, the Company entered into an Agreement and Plan of
Exchange (the "Airtron Agreement") with Airtron, Inc. ("Airtron") and certain
of its shareholders, pursuant to which $20.4 million in cash, 14.9 million
shares of the Company preferred stock and 4.7 million shares of the Company
common stock were issued to shareholders of Airtron in exchange for all of the
then outstanding shares of Airtron. Although for legal purposes Airtron was
acquired by the Company, for accounting purposes the transaction was accounted
for as a reverse acquisition, as if Airtron acquired the Company, due to the
fact that the former shareholders of Airtron then owned a majority of the
Company common stock. In connection with the purchase of the Company, the
consideration paid to the shareholders of the Company was recorded as non-
recurring compensation expense of $7.0 million in the accompanying
consolidated statements of operations for the ten months ended December 31,
1997. The consolidated financial statements presented herein for the periods
prior to the effective date of the acquisition only include the accounts of
Airtron. The consolidated statements of shareholders' equity have been
converted from Airtron's capital structure to the Company's capital structure
to reflect the exchange of shares pursuant to the Airtron Agreement. The cash
and redeemable preferred stock paid to the Airtron shareholders, net of
existing liabilities to former shareholders, have been treated as a
distribution to the Airtron shareholders. All significant intercompany
balances have been eliminated. Concurrent with the initial public offering of
the Company's common stock in November 1997 (the "IPO"), the Company changed
its fiscal year end from February 28 to December 31.

  As of December 31, 1999, the Company was comprised of 73 operating companies
performing services in 64 cities across 28 states. Through its acquisitions,
the Company has increased the portion of its business derived from
commercial/industrial customers and focused its acquisition program on
companies that could further the implementation of the Company's national
accounts initiatives. The Company has also significantly expanded its
electrical and data cabling business through these acquisitions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Use of Estimates

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

 Revenue Recognition

  Revenues from work orders are recognized as services are performed. Revenues
from service and maintenance contracts are recognized over the life of
contracts. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--Continued

 Cash and Cash Equivalents

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

 Inventories

  Inventories consist primarily of purchased materials and supplies. The
inventory is valued at the lower of cost or market, with cost determined on a
first-in, first-out ("FIFO") basis.

 Property and Equipment

  Property and equipment is stated at cost. Depreciation is computed
principally using the straight-line method over the useful lives of the
assets. Leasehold improvements are amortized over the shorter of the remaining
lease term or the estimated useful life of the asset.

  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the consolidated statements of operations.

 Goodwill

  Goodwill represents the excess of the aggregate purchase price over the fair
value of net assets acquired and is amortized on a straight-line basis over a
period of 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows compared to
the carrying value of goodwill. The Company will reassess the recoverability
of goodwill if estimated future operating cash flows are not achieved.

 Deferred Debt Issue Costs

  Deferred debt issue costs related to the Company's revolving credit
agreement and senior subordinated notes are included in other noncurrent
assets and amortized to interest expense over the scheduled maturity of the
debt.

 Stock-Based Compensation

  Statement of Financial Accounting Standards ("SFAS") No. 123, Accounting for
Stock-Based Compensation, encourages but does not require companies to record
compensation expense for stock-based employee compensation plans at fair
value. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and
related Interpretations. Accordingly, compensation expense for stock options
is measured as the excess, if any, of the quoted market price of the Company's
common stock at the date of the grant over the amount an employee must pay to
acquire the common stock.

 Warranty Costs

  The Company generally warrants all of its work for a period of one year from
the date of installation. A provision for estimated warranty costs is made at
the time a product is sold or service is rendered.

 Income Taxes

  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

 Earnings Per Share

  Weighted average shares outstanding for each of the periods presented were
as follows (in thousands):

</TABLE>

  Basic earnings per share have been calculated by dividing net income (loss)
by the weighted average number of common shares outstanding. Diluted earnings
per share are computed by dividing net income by the weighted average number
of common shares outstanding plus potentially dilutive common shares.

  Because the Company reported a net loss for the ten months ended December
31, 1997, the potentially dilutive common shares (including warrants and stock
options discussed in Note 9) had an anti-dilutive effect on earnings per
share. As of December 31, 1999 and 1998, options to purchase 3.4 million and
0.4 million shares of common stock and warrants to purchase 0.6 million and
1.3 million shares of common stock, respectively, were not included in the
calculation of diluted earnings per share because the options' or warrants'
exercise price was greater than the average market price of the common shares.

 Reclassifications

  Certain amounts recorded in the year ended December 31, 1998 and the ten
months ended December 31, 1997 have been reclassified to conform with the
current year presentation.

3. BUSINESS COMBINATIONS

  During 1997, the Company acquired 23 companies for approximately $44.2
million in cash, 4.5 million shares of common stock, 4.4 million shares of
redeemable preferred stock (which were retired in connection with the IPO),
options to acquire 0.1 million shares of common stock and warrants to purchase
0.5 million shares of common stock. Of the total recorded consideration,
approximately $3.2 million of cash and 0.5 million shares of common stock were
due to former owners at December 31, 1997. During 1998, a reduction of
approximately $1.0 million in cash and 0.1 million shares of common stock was
recorded to reflect final settlements on certain 1997 acquisitions. Also
during 1998, payments of approximately $1.9 million in cash and 0.4 million
shares of common stock were made to former shareholders on certain 1997
acquisitions.

  During 1998, the Company completed the acquisition of 39 platform and five
tuck-in companies for approximately $194.8 million in cash, $4.0 million of
notes payable, $16.0 million of junior subordinated debt, 12.1 million shares
of common stock, options to purchase 0.3 million shares of common stock and
warrants to purchase 0.8 million shares of common stock. Of the total
consideration, approximately $7.2 million of cash was due to former owners at
December 31, 1998. During 1999, the Company paid approximately $6.1 million of
cash related to previously recorded amounts due to former shareholders of
companies acquired prior to December 31, 1998. In addition, the Company
reduced amounts due to former shareholders by approximately $1.1 million
related to final purchase price settlements.

  During 1999, the Company completed the acquisition of 14 additional
companies, including 13 platform companies and one satellite location. These
companies were acquired for approximately $181.4 million, which includes cash
payments of $115.2 million, $4.1 million in junior subordinated notes, 5.1
million shares of common stock and warrants to purchase approximately 80,000
shares of common stock. Of the total consideration, approximately $6.6 million
of cash was due to former owners at December 31, 1999.

  In conjunction with the above mentioned acquisitions, the Company assumed
$35.4 million, $26.2 million and $16.1 million of debt for acquisitions
completed in 1999, 1998 and 1997, respectively.

  For the above mentioned acquisitions, the common stock, options and warrants
were valued at estimated fair value at the time of the respective acquisition
and the preferred stock was valued at its redemption value of $1 per share.
For certain 1999 acquisitions, allocation of purchase price to the assets
acquired and liabilities assumed has been initially assigned and recorded
based on preliminary estimates of fair value and may be revised as additional
information becomes available. Such additional information includes appraisals
on property, contingent liabilities of the acquired business, and working
capital settlements related to the acquisition consideration and the net
assets acquired. However, the Company does not expect any significant
adjustments to the purchase price allocations or amount of goodwill at
December 31, 1999.

  Several former owners of businesses acquired by the Company have the ability
to receive additional amounts of purchase price, payable in cash and/or common
stock contingent upon the occurrence of future events. The Company records
such contingent consideration as additional purchase price when earned. During
1997, approximately $0.3 million in cash and 22,500 shares of common stock
were earned and due to former owners related to these contingent payments.
These amounts were paid in 1998. During 1998, approximately $5.2 million of
cash and 0.3 million shares of common stock were earned related to these
contingent payments, of which approximately $3.3 million of cash and 0.3
million shares of common stock were due to former owners as of December 31,
1998 and were subsequently paid in 1999. During 1999, approximately $5.0
million of cash and 0.1 million shares were earned related to these contingent
payments, of which approximately $4.0 million of cash and 0.1 million shares
of common stock remained due to former owners as of December 31, 1999.
Additional cash and common stock may become payable in 2000 through 2002
contingent upon future events.

  On December 11, 1997, the Company entered into a three-year revolving credit
agreement (the "Credit Agreement"), which was subsequently amended and
restated to increase the borrowing capacity. As of December 31, 1999 the
Credit Agreement provided for a borrowing capacity of $425 million. Borrowings
under the Credit Agreement are guaranteed by the Company's domestic
subsidiaries, including future domestic subsidiaries. The obligations of the
Company under the Credit Agreement and the obligations under the guarantees
are secured by a first priority lien on the accounts receivable and inventory
of the domestic subsidiaries, and by a pledge of stock of its domestic
subsidiaries.

  Borrowings under the Credit Agreement bear interest at a rate per annum, at
the Company's option, of either (1) the Alternate Base Rate or (2) the
Eurodollar Rate. The Alternate Base Rate is equal to the greater of the

Federal Funds Effective Rate plus 0.5% or the Prime Rate plus a Margin
depending on the ratio of indebtedness for borrowed money to EBITDA (with all
capitalized terms as defined in the Credit Agreement). The Eurodollar Rate is
the rate defined in the Credit Agreement plus a Margin depending on the ratio
of indebtedness for borrowed money to EBITDA. The Company is subject to
commitment fees payable quarterly in arrears and administration fees payable
annually to the Agent until such time as the Credit Agreement is terminated.
The commitment fees range from 0.25% to 0.375% per annum with respect to the
unused commitments under the Credit Agreement depending on the ratio of
indebtedness for borrowed money to EBITDA. In addition, the Company paid
various underwriting and arrangement fees and closing costs associated with
the origination and syndication of the Credit Agreement. The unamortized
portion of these expenses is included as deferred debt issue costs in the
accompanying consolidated balance sheets and amounted to approximately $2.9
million and $2.4 million at December 31, 1999 and 1998, respectively.

  Under the Credit Agreement, the Company is required to maintain certain
financial covenants and tests, including: (1) a minimum Fixed Charge Coverage
Ratio; (2) a maximum ratio of total indebtedness for borrowed money to
capitalization (as defined in the Credit Agreement); (3) a maximum ratio of
senior debt to pro forma earnings before interest, taxes, depreciation and
amortization; (4) a maximum ratio of total indebtedness to EBITDA; (5) a
minimum amount of Consolidated Net Worth (as defined in the Credit Agreement)
and (6) a maximum amount of Capital Expenditures in relation to Consolidated
Net Worth. The Credit Agreement places limitations upon the amount of letters
of credit which may be drawn, investments which may be permitted, and liens
which may be granted to secure other debt. The Company may not pay any
dividends or redeem, retire or guarantee the value of shares of any class of
stock in the Company without prior approval from the lending banks, other than
the purchase of outstanding shares of the Company's stock within defined
limits. At December 31, 1999, the Company was in compliance with these
covenants. The Credit Agreement matures on October 13, 2001. Subsequent to
year-end 1999, the Company refinanced the Credit Agreement with borrowings
under a new credit facility (see Note 18).

  In connection with the acquisition of Trinity Contractors, Inc. ("Trinity"),
the Company paid cash and issued $16.0 million of subordinated notes (the
"Trinity Notes"), common stock and warrants to purchase common stock (the
"Trinity Warrants"). Unless prepaid in whole or part at any time by the
Company, the balance of the Trinity Notes was due in November 2003. Holders of
the Trinity Notes had a one-time option to require the Company to repurchase
the Trinity Notes (the "Put Option") in the event the Company issued
$50,000,000 or more in principal amount of debt that met certain criteria. In
connection with the private placement offering in January 1999 discussed
below, the Put Option was exercised by substantially all the holders of the
Trinity Notes, such notes were repaid by the Company and the related Trinity
Warrants were surrendered.

  In January 1999, the Company completed a private placement offering (the
"Offering") of $130 million of unsecured senior subordinated notes bearing
interest at 9.75% and maturing in January 2009. The net proceeds of the
offering were used to repay indebtedness incurred under the Credit Agreement.
These notes were subsequently exchanged for identical notes registered under
the Securities Act of 1933, as amended (the "Notes").

  The Notes are guaranteed by all of the Company's current and future U.S.
subsidiaries other than "Unrestricted Subsidiaries" (as defined in the
indenture governing the Notes). As of December 31, 1999, there were no
"Unrestricted Subsidiaries." These guarantees are full, unconditional and
joint and several. Accordingly, no separate financial statements of the
guarantor subsidiaries are presented because management believes this
information is not material to users of its financial statements.

  The Notes pay interest semi-annually commencing July 15, 1999 and are
redeemable at the option of the Company at any time on or after January 15,
2004. Additionally, the Notes' indenture has restrictive covenants

or limitations on the payment of dividends, the distribution or redemption of
capital stock, the incurrence of debt and the sale of assets.

  The Company entered into an agreement to lock in the ten year U.S. Treasury
rate used to price the offering of the Notes. The Company locked in $100
million at 5.5212%, which management believes is an attractive long-term base
rate. This agreement expired on January 31, 1999, and was settled on that date
based upon the ten year Treasury yield of 4.648%, resulting in an additional
pre-tax financing cost of approximately $6.9 million. In accordance with SFAS
No. 80, Accounting for Futures Contracts, this agreement qualified as a hedge
and was recognized as deferred debt issue costs. The Company has also paid
various underwriting and closing costs associated with the Offering. The
unamortized portion of all costs related to the Offering is included as
deferred debt issue costs in the accompanying consolidated balance sheets and
amounted to approximately $10.0 million and $6.9 million at December 31, 1999
and 1998, respectively. Subsequent to December 31, 1999, the Company
refinanced the Notes with borrowings under a new credit facility (see Note
18).

  The aggregate maturities of debt as of December 31, 1999 are as follows (in

8. DUE TO RELATED PARTIES

  Under the Airtron Agreement, part of the cash purchase price payable to
former shareholders of Airtron related to the tax benefits which have been
received by the Company related to the exercise of previously outstanding
warrants and distributions under deferred compensation arrangements. The
Company recognized liabilities of $9.7 million at the date of acquisition as
an estimate of these amounts. This amount was paid to the former shareholders
of Airtron as the tax benefit was realized by the Company either through
receipt of net operating loss carryback claims or utilization of current
deductions and net operating loss carryforwards to reduce estimated tax
payments. During 1998, the Company was able to realize certain tax benefits
under the Airtron Agreement and correspondingly paid $5.3 million of the
original liability to the former shareholders. As of December 31, 1998, the
$4.4 million remaining liability and the related refundable income taxes and
deferred tax assets were reflected as current assets and liabilities in the
December 31, 1998 consolidated balance sheet as all remaining tax benefits
were realized during 1999.

9. STOCK-BASED PLANS

  The Company has implemented the following stock-based programs for its
employees and others:

  Stock Awards Plan--In August 1997, the Company adopted the Group Maintenance
America Corp. 1997 Stock Awards Plan which provides the Company the latitude
to grant a variety of awards, such as stock options, stock appreciation rights
("SARs"), restricted stock, performance awards and phantom stock awards, to
officers, directors, key employees and other persons working for the Company
and its subsidiaries. The plan requires that options and SARs be granted at
not less than the fair market value of a share of common stock on the grant
date. The plan also requires that no stock option granted shall vest in less
than six months after the grant date. The

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--Continued

Company may issue not more than 9% of the number of total shares outstanding
(determined on a quarterly basis) under the plan, which will terminate on June
30, 2007. At December 31, 1999, options to purchase 3.4 million shares at an
average exercise price of $12.84 were outstanding under this plan.

  Stock Option Plan--In August 1997, the Company adopted the Group Maintenance
America Corp. 1997 Stock Option Plan under which the Company may grant options
to employees who are not eligible for awards under the Stock Awards Plan. The
plan requires that options be granted at not less than fair market value of a
share of common stock on the grant date. The plan also requires that no stock
option granted shall vest in less than six months after the grant date. The
Company may issue not more than 3% of the number of shares outstanding
(determined on a quarterly basis) under this plan, which will terminate on
June 30, 2007. At December 31, 1999, options to purchase 0.7 million shares at
an average exercise price of $13.97 were outstanding under this plan.

  Founder Options--Between October 1996 and August 1997, the Company granted
to directors, senior management and other employees options to purchase an
aggregate of 388,800 shares of common stock at an exercise price of $3.08.
These options vest and expire over various periods. At December 31, 1999,
options to purchase 352,000 shares of common stock were outstanding under this
plan.

  During 1999 and 1998, the Company issued options to purchase approximately
0.8 million and 1.6 million shares of common stock at a weighted average
exercise price of $13.17 and $14.32, respectively. These options vest at a
rate of 25% per year and expire at various dates during 2003 and 2004.

  Additionally, the Company issued options to purchase 0.3 million and 0.1
million shares of common stock in connection with acquisitions at a weighted
average exercise price of $4.09 and $11.89 in 1998 and 1997, respectively.
These options were valued at $3.4 million and $1.2 million in 1998 and 1997,
respectively, and are included in the purchase price of the acquired company.
Substantially all of these options are immediately exercisable.

  As consideration for a company acquired in January 1999, the Company issued
80,000 warrants to purchase shares of common stock at $19.50 per share. These
warrants were valued at $0.4 million and are included in the purchase price of
the acquired company. As consideration for a company acquired in November
1998, the Company issued 829,000 warrants to purchase shares of common stock
at $19.30 per share. As indicated in Note 7, substantially all of the warrants
issued in November 1998 were surrendered in January 1999 and accordingly no
value was included for these warrants in the purchase price of the acquired
company. In connection with the purchase of one company in July 1997, the
Company issued warrants to purchase 514,000 shares of common stock at $17.50
per share. These warrants were valued at $1.0 million and are included in the
purchase price of the acquired company. There were no options issued in
connection with acquisitions during 1999.

  The Company applies Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees, in accounting for its stock options (other than
options issued in connection with acquisitions). Accordingly, compensation
cost has been recognized only for the options that have an exercise price less
than the fair market value of the underlying stock at the date of grant. A
compensation charge of approximately $0.2 million is reflected in the
consolidated statements of operations and shareholders' equity for each of the
years ended December 31, 1999 and 1998 and the ten months ended December 31,
1997 related to the issuance of management shares and stock options at prices
below the fair market value at the date of issue or grant.

  The following pro forma data is calculated as if compensation expense for
the Company's stock option plans were determined based on the fair value at
the grant date for awards under these plans consistent with the methodology
prescribed under SFAS No. 123, Accounting for Stock-Based Compensation (in

10. SHAREHOLDERS' EQUITY

  On October 24, 1996, the Company entered into a stock subscription agreement
with an individual providing for the sale of up to 2.6 million shares of
common stock at a purchase price of $3.08 per share. At December 31, 1997, the
Company had sold all of the 2.6 million shares.

  During November and December 1997, the Company completed the IPO involving
the sale of 8.3 million shares of common stock at a price to the public of
$14.00 per share. The net proceeds from the IPO (after deducting underwriting
discounts and commissions and offering expenses) were approximately $103.6
million. Of this amount, $29.8 million was used to pay the cash portion of the
closing consideration relating to certain acquired businesses, $42.6 million
to repay corporate indebtedness and debt assumed in connection with the
acquisition of businesses, $19.3 million to retire all of the then outstanding
preferred stock and $11.9 million for general corporate purposes including
working capital, final consideration settlements related to acquired
businesses and future acquisitions. In March 1998, the Company issued $0.8
million of subordinated convertible debentures to fund a portion of the
consideration of one acquisition. These debentures were converted to 68,000
shares of common stock during 1998.

  As discussed in Note 8, under the Airtron Agreement, the Company received
certain tax benefits related to the exercise of previously outstanding
warrants and distributions under deferred compensation arrangements. The
Company repaid a portion of these benefits to the former shareholders of
Airtron as the benefits were realized. In addition to the tax benefits paid to
the former shareholders, the Company realized additional tax benefits during

  Total rental expense for the years ended December 31, 1999 and 1998 and the
ten months ended December 31, 1997 was approximately $22.0 million, $13.5
million and $2.3 million, respectively (including $5.6 million, $4.3 million
and $1.2 million, respectively, to related parties).

13. EMPLOYEE BENEFIT PLANS

  Effective January 1, 1999, the Company adopted a defined contribution
savings plan (the "Savings Plan") to consolidate and replace the existing
defined contribution employee retirement plans at acquired companies. In
addition, certain of the Company's subsidiaries maintain defined contribution
employee retirement plans that have not yet been merged into the Savings Plan.
These plans are open to certain employees after various lengths of service.
Employee contributions and employer matching contributions occur at different
rates and the matched portions of the funds vest over a period of years.
Company contributions to these plans totaled approximately $7.1 million, $4.8
million and $0.4 million for the years ended December 31, 1999 and 1998 and
the ten months ended December 31, 1997, respectively.

  Certain of the Company's subsidiaries make contributions to union-
administered benefit funds that cover the majority of these companies' union
employees. For the years ended December 31, 1999 and 1998 and the ten months
ended December 31, 1997, the participant costs charged to operations were
approximately $24.3 million, $8.8 million and $0.6 million, respectively.
Governmental regulations require that, in the event of plan termination or
employer withdrawal, an employer may be liable for a portion of the plan's
unfunded vested benefits, if any. The Company is not aware of any liabilities
resulting from unfunded vested benefits related to union administered benefit
plans. The Company does not anticipate withdrawal from the plans, nor is the
Company aware of any expected plan terminations.

14. COMMITMENTS AND CONTINGENCIES

  The Company is involved in various legal actions. It is not possible to
predict the outcome of these matters; however, in the opinion of management,
the resolution of these matters will not have a material adverse effect on the
Company's consolidated financial position or results of operations.

15. FINANCIAL INSTRUMENTS

  The Company's financial instruments consist of cash and cash equivalents and
short- and long-term debt. The Company believes that the carrying values of
these instruments on the accompanying consolidated balance sheets approximate
their fair value.

16. OPERATING SEGMENTS

  The Company's reportable segments are strategic business units that offer
products and services to two distinct customer groups. They are managed
separately because each business requires different operating and marketing
strategies.

  The Company has two reportable segments: commercial/industrial and
residential markets. The commercial/industrial segment provides maintenance,
repair and replacement services and new installation services in manufacturing
and processing facilities, power generation facilities, hospitals and other
critical care facilities, colleges and universities, hotels, commercial office
buildings and complexes, retail stores and restaurants, supermarkets and
convenience stores. The residential segment provides maintenance, repair and
replacement services and new installation services in single family and low-
rise multifamily housing units.

  The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. The Company evaluates
performance based on income from operations of the respective business units
prior to unallocated corporate expenses.

  Other activities include financial data of two operating subsidiaries that
provide products and services outside of those performed by the Company's two
primary operating segments. Unallocated corporate expenses primarily include
(1) corporate overhead, (2) corporate and operating company management
bonuses, and (3) savings from national purchase agreements relating to
materials and property/casualty insurance. Assets, capital expenditures and
depreciation expense for the corporate function are included in the "Other"
column in the presentation below.

18. EVENTS SUBSEQUENT TO INDEPENDENT AUDITORS' REPORT

  On February 22, 2000, the shareholders of both GroupMAC and Building One
Services Corporation (Building One) approved a merger of the two companies.
Under the terms of the merger, each outstanding share of Building One common
stock was converted into 1.25 shares of GroupMAC common stock. In addition,
approximately 11,052,000 shares of GroupMAC common stock were converted into
cash at a rate of $13.50 per share pursuant to a cash election right available
to GroupMAC shareholders. In connection with the closing of the merger,
GroupMAC amended its articles of incorporation to change its name to Encompass
Services Corporation.

  Concurrent with the closing of the merger, an affiliate of Apollo
Management, L.P. exchanged $106 million of Building One convertible junior
subordinated debentures and $150 million of cash for approximately $256
million of Encompass convertible preferred stock. The preferred stock will
mature in 2012, will bear a dividend yield coupon rate of 7.25% and will be
convertible into shares of Encompass common stock at an initial conversion
price of $14 per common share. The proceeds from the issuance of the
convertible preferred stock were used to fund the cash election feature of the
merger.

  On February 22, 2000, Encompass entered into a new credit agreement to
provide a total of $800 million in financing. The proceeds of this new credit
agreement were used to refinance the existing revolving credit facilities of
GroupMAC and Building One, as well as GroupMAC's senior subordinated notes. In
addition, Encompass assumed the 10 1/2% Senior Subordinated Notes due 2009 of
Building One.

  GroupMAC was the surviving legal entity in the merger. However, for
accounting purposes, Building One is deemed to be the acquiror and,
accordingly, the merger will be accounted for as a "reverse acquisition."
Under this method of accounting, Encompass' historical results for periods
prior to the merger will be the same as Building One's historical results.

                         INDEPENDENT AUDITORS' REPORT

The Board of Directors
Group Maintenance America Corp.

  We have audited the accompanying balance sheets of Group Maintenance America
Corp. (the Company) as of December 31, 1996 and April 30, 1997, and the
related statements of operations, shareholders' equity (deficit), and cash
flows for the periods from October 21, 1996 (inception) to December 31, 1996
and the four months ended April 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the 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

                        GROUP MAINTENANCE AMERICA CORP.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

  Group Maintenance America Corp. (the Company or GroupMAC Parent) was
incorporated in October 1996 and, therefore, the financial statements reflect
the period since the Company's inception through December 31, 1996 and the
four months ended April 30, 1997. The Company's primary business is to build a
national company providing heating, ventilation and air conditioning (HVAC),
plumbing and electrical services.

  Effective April 30, 1997, GroupMAC Parent entered into an Agreement and Plan
of Exchange (the Agreement) with Airtron, Inc. (Airtron), in which $20,366,951
in cash, 14,873,133 shares of GroupMAC Parent preferred stock and 4,652,140
shares of GroupMAC Parent common stock were issued to shareholders of Airtron
in exchange for 100 percent of the then outstanding shares of Airtron. In
connection with this merger the combined company is referred to as GroupMAC
and Subsidiaries. The Agreement closed on May 2, 1997 with the cash portion
funded by the Company's available credit facility and a capital contribution
from a shareholder pursuant to a stock subscription agreement (see note 6).
For accounting purposes, the transaction was accounted for as a reverse
acquisition, as if Airtron acquired GroupMAC Parent, as the former
shareholders of Airtron then owned a majority of GroupMAC Parent's common
stock. Concurrent with this transaction, the resulting combined entity will be
named Group Maintenance America Corp. and Subsidiaries. The Company is
included in the consolidated financial statements of GroupMAC and
Subsidiaries, presented elsewhere herein, for periods subsequent to the
effective date of the acquisition.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Use of Estimates

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

 Cash and Cash Equivalents

  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with original maturities of three months or
less to be cash equivalents. There were no cash payments for interest or
income taxes in 1996 or in the four months ended April 30, 1997.

Property and Equipment

  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.

  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures of major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.

 Income Taxes

  The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards No. 109. Under
this method deferred income taxes are recorded based upon differences between
the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets or liabilities are received or settled.

                        GROUP MAINTENANCE AMERICA CORP.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


  The Company has recorded a full valuation allowance against all deferred tax
assets due to the uncertainty of ultimate realizability. Accordingly, no
income tax benefit has been recorded for the losses incurred.

5. LONG-TERM DEBT

 Credit Agreement

  In May 1997, the Company entered into a credit agreement (the Credit
Agreement) with a group of banks providing for secured facilities consisting
of an 18-month revolving credit line of $3 million, a six-year term loan of
$20 million used in connection with the acquisition of Airtron (see note 1)
and a term loan facility, available until October 31, 1998, providing for up
to $12 million in term loans having a final maturity six years after the date
of the Credit Agreement, to be used in connection with future acquisitions.
Loans under the revolving credit facility are limited to a borrowing base
consisting of 70% of eligible accounts receivable. Interest on outstanding
borrowings is payable in quarterly installments beginning August 31, 1997. A
commitment fee of .25% is payable on the unused portion of the revolving
credit line.

  The Credit Agreement contains covenants which, among other matters, restrict
or limit the ability of the Company to pay dividends, incur indebtedness, make
capital expenditures and repurchase capital stock. The Company must also
maintain a minimum fixed charge coverage ratio (as defined) and certain other
ratios, among other restrictions.

                        GROUP MAINTENANCE AMERICA CORP.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


  As of June 30, 1997, available borrowing capacity under the Credit Agreement
was $5.4 million.

 Long-Term Debt

  On October 24, 1996, the Company executed a $75,000 subordinated note with a
Texas limited liability company. The note bears interest at eight percent (8%)
and is payable upon the earlier of (i) the closing of the Company's first
public offering of its common stock or (ii) two years from the date of the
note. The note is subordinate to all indebtedness of the Company to the banks
and is guaranteed by certain officers of the Company.

6. SHAREHOLDERS' EQUITY (DEFICIT)

 Common Stock

  The Company is authorized to issue 100 million shares of common stock, $.001
par value. There were 1,211,345 and 1,611,345 shares of common stock issued
and outstanding at December 31, 1996 and April 30, 1997, respectively. In
connection with the sale of certain shares of common stock to management, a
nonrecurring, noncash compensation charge of $206,250 was recorded in 1996 to
reflect the difference between the amount paid for the shares and the
estimated fair value of the shares on the date of sale.

  On October 24, 1996, the Company entered into a stock subscription agreement
with an individual allowing for the purchase of up to 2.6 million shares of
common stock at a purchase price of $3.08 per share. Under this agreement, 0.2
million shares were purchased in October 1996, 0.2 million in January 1997 and
0.2 million in April 1997 and additional shares are required to be purchased
upon written notice from the Company, but in no event later than October 24,
1998. Subsequent to April 30, 1997, an additional 1.658 million shares have
been purchased under the Subscription Agreement.

 Preferred Stock

  The Company is authorized to issue up to 50 million shares of preferred
stock, par value $.001 per share, in one or more series. As of December 31,
1996 and April 30, 1997, none were outstanding.

 Options

  Under an option agreement dated October 24, 1996, the Company is authorized
to grant stock options with respect to 388,800 shares of the Company's common
stock to directors and senior management.

  The following is a summary of stock option activity and number of shares
reserved for outstanding options.

  At April 30, 1997, options representing 28,000 shares were available to be
granted under the option agreement.

                        GROUP MAINTENANCE AMERICA CORP.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


  The Company has adopted the disclosure-only provisions of the Statement of
Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-based
Compensation. Accordingly, no compensation cost has been recognized for the
option agreement as all options have an exercise price equal to or greater
than the fair value of the underlying stock at date of grant. Had compensation
cost for the Company's stock option plan been determined consistent with the
provisions of SFAS No. 123, net loss would have been increased by the
following pro forma amounts:

<TABLE>

                                                      1996) through    ended
                                                      December 31,   April 30,

      <S>                                             <C>           <C>
      Net loss:
        As reported..................................   $(722,517)  $(1,780,743)
        Pro forma....................................   $(745,602)  $(1,837,870)
</TABLE>

  The pro forma compensation cost may not be representative of that to be
expected in future years because options vest over several years and
additional awards may be made each year.

  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted average
assumptions used by the plan for fiscal 1996 and for the four months ending
April 30, 1997: no dividend yield; expected volatility of 0%; risk-free
interest rate of 6.26%; and expected lives of ten years. The weighted average
fair value per share of the options granted during fiscal 1996 and in the four
months ending April 30, 1997 is estimated to be $1.425.

7. INCOME TAXES

  There is no Federal income tax provision as losses were incurred and a
valuation allowance has been established against future benefits deriving from
the carryforward of these losses.

8. COMMITMENTS AND CONTINGENCIES

  The Company has entered into various operating lease agreements, primarily
for office space, furniture and service equipment. Minimum annual rental
payments under non-cancelable operating leases as of June 30, 1997, were
approximately as follows:

<TABLE>
<CAPTION>
      For the year ending April 30,
      -----------------------------
      <S>                                                                <C>
      1997.............................................................. $46,000
      1998..............................................................     600
      1999..............................................................     300
</TABLE>

  Rental expense under operating leases was $9,032 for the period ended
December 31, 1996 and $49,194 for the four months ending April 30, 1997.

9. EVENT SUBSEQUENT TO INDEPENDENT AUDITORS' REPORT--STOCK SPLIT

  On August 16, 1997, the Company's Board of Directors declared a 1-for-2.5
reverse stock split of the Company's common stock. All share data included in
the consolidated financial statements have been restated to reflect the stock
split.

(4)  Article VII is amended in its entirety to be as follows:

"ARTICLE VII

BOARD OF DIRECTORS

     (1) The property, affairs and business of the Corporation shall be managed
by or under the direction of the Corporation's board of directors.  Subject to
the rights of the holders of any series of Preferred Stock, the number of
directors constituting the board of directors of the Corporation shall not be
less than nine (9) nor more than eighteen (18).  Subject to the rights of the
holders of any series of Preferred Stock, the number of directors shall be
determined from time to time hereafter exclusively pursuant to a resolution
adopted by the affirmative vote of a majority of the entire board of directors.
For purposes of these Restated Articles of Incorporation, the "entire board of
directors" shall mean the number of directors that would be in office if there
were no vacancies nor any unfilled newly created directorships.  Directors need
not be residents of the State of Texas or shareholders of the Corporation.
Until the third annual meeting of shareholders following effectiveness of these
Restated Articles of Incorporation under the TBCA, the directors shall be
divided into three classes, which shall consist, as nearly as possible, of one-
third of the total number of directors constituting the entire Board of
Directors, and designated Class I, Class II and Class III, respectively. Each
director elected or appointed prior to the effectiveness of these Restated
Articles of Incorporation under the TBCA shall serve for their full term, such
that the term of each Class I director shall end at the second succeeding annual
meeting of shareholders following effectiveness of these Restated Articles of
Incorporation, the term of each Class II director shall end at the third
succeeding annual meeting of shareholders following effectiveness of these
Restated Articles of Incorporation, and the term of each Class III director
shall end at the first succeeding annual meeting of shareholders following
effectiveness of these Restated Articles of Incorporation. The term of each
director elected after the effectiveness of these Restated Articles of
Incorporation whether at an annual meeting or to fill a vacancy in the board of
directors arising for any reason, including any increase in the size of the
board of directors, shall end at the first annual meeting following his or her
election. Commencing with the third annual meeting of shareholders following the
effectiveness of these Restated Articles of Incorporation, the foregoing
classification of the board of directors shall cease, and all directors shall be
of one class and serve for a term ending at the annual meeting following the
annual meeting at which the director was elected. In no case shall a decrease in
the number of directors shorten the term of any incumbent director. Each
director shall hold office after the annual meeting at which his or her term is
scheduled to end until his or her successor shall be elected and shall qualify,
subject, however, to prior death, resignation, disqualification or removal from
office in accordance with the TBCA. Any newly created directorship resulting
from an increase in the number of directors may be filled by a majority of the
board of directors then in office, provided that a quorum is present, and any
other vacancy on the board of directors may be filled by a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director.

     (2) Notwithstanding anything else contained in these Restated Articles of
Incorporation, whenever holders of any one or more series of Preferred Stock
shall have the right, voting separately by class or series, to elect directors
at any annual or special meeting of shareholders, the election, term of office,
filling of vacancies and other features of such directorships shall be governed
by the provisions applicable to such class or series established pursuant to
Paragraph 1 of Article IV hereof. Directors shall be elected by such holders
annually unless expressly provided otherwise by the terms of such class or
series of Preferred Stock.

                                       2
<PAGE>

     (3) No director of the Corporation shall be removed from office as a
director by vote or other action of the shareholders or otherwise except for
cause."

(5)  Article XII is hereby deleted in its entirety.

(6)  Article XIII is amended in its entirety to be as follows:


                                  "ARTICLE XII

                 PROVISIONS APPLICABLE TO BUSINESS COMBINATIONS

     1.   Vote Required for Certain Business Combinations.  In addition to any
affirmative vote required by law or these Articles of Incorporation or the
Bylaws of the Corporation, and except as otherwise expressly provided in Section
2 of this Article XII, a Business Combination (as hereinafter defined) with, or
proposed by or on behalf of, any Interested Shareholder (as hereinafter defined)
or any Affiliate or Associate (as hereinafter defined) of any Interested
Shareholder or any person who thereafter would be an Affiliate or Associate of
such Interested Shareholder, shall require the affirmative vote of not less than
eighty percent (80%) of the votes entitled to be cast by the holders of all of
the then outstanding shares of Voting Stock (as hereinafter defined), voting
together as a single class, and the affirmative vote of not less than a majority
of the votes entitled to be cast by the Voting Stock beneficially owned by
persons other than such Interested Shareholder. Each share of Voting Stock shall
have the number of votes granted to it in, or duly fixed by the board of
directors pursuant to, Article IV of these Articles of Incorporation.  Such
affirmative vote shall be required notwithstanding the fact that no vote may be
required, or that a lesser percentage or separate class vote may be specified,
by law, or in any agreement of the Corporation with any national securities
exchange or otherwise.

     2.   Exceptions to Higher Vote Requirement.  The provisions of Section 3 of
this Article XII shall not be applicable to any particular Business Combination,
and such Business Combination shall require only such affirmative vote, if any,
as is required by law or by any other provision of these Articles of
Incorporation or the Bylaws of the Corporation, or any agreement with any
national securities exchange, if all of the conditions specified in any of the
following Paragraphs (a), (b) or (c) are met or, in the case of a Business
Combination not involving the payment of consideration to the holders of the
Corporation's outstanding Capital Stock (as hereinafter defined), if the
condition specified in the following Paragraph (a) is met:

          (a)     The Business Combination shall have been approved either
     specifically, or as a transaction which is within a series of related
     transactions described with reasonable specificity, by at least an eighty
     percent (80%) vote of the Continuing Directors (as hereinafter defined),
     who shall at the time constitute at least a majority of the Whole Board (as
     hereinafter defined) (whether or not such approval occurs prior to or
     subsequent to the acquisition of, or announcement or public disclosure of
     the intention to acquire, beneficial ownership of the Voting Stock that
     caused the Interested Shareholder to become an Interested Shareholder).

          (b) All of the following conditions shall have been met:

               (i) The aggregate amount of cash and the Fair Market Value (as
          hereinafter defined), as of the date of the consummation of the
          Business Combination, of consideration other than cash to be received
          per share by holders of Common Stock of the Corporation in such
          Business Combination shall be at least equal to the higher amount
          determined under clauses (A) and (B) below:

                    (A) (If applicable) the highest per share price (including
               any brokerage commissions, transfer taxes and soliciting dealers'
               fees) ("Highest

               Purchase Price") paid by or on behalf of the Interested
               Shareholder for any share of Common Stock in connection with the
               acquisition by the Interested Shareholder of beneficial ownership
               of shares of Common Stock,

                         (x) within the two-year period immediately prior to the
                    first public announcement of the proposed Business
                    Combination (the "Announcement Date"), or

                         (y) in the transaction in which it became an Interested
                    Shareholder,

               whichever is higher, in either case, as adjusted for any
               subsequent stock split, stock dividend, subdivision or
               reclassification with respect to the Common Stock; provided that
               if the Business Combination is effected more than 180 days after
               the last date upon which such Interested Shareholder paid the
               Highest Purchase Price, then the consideration to be received by
               the shareholders shall be increased by Interest (as hereinafter
               defined) with respect to the period from the date the Interested
               Shareholder paid the applicable Highest Purchase Price to the
               effective date of the Business Combination ("Adjustment Period").

                    (B) The Fair Market Value per share of Common Stock on the
               Announcement Date or on the date (the "Determination Date") on
               which the Interested Shareholder became an Interested
               Shareholder, whichever is higher, as adjusted for any subsequent
               stock split, stock dividend, subdivision or reclassification with

                         (x) within the two-year period immediately prior to the
                    Announcement Date, or

                         (y)    in the transaction in which it became an
                    Interested Shareholder,

          of the Interested Shareholder in connection with its direct or

               outstanding Capital Stock;

                    (B) There shall have been no reduction in the annual rate of
               dividends paid on the Common Stock (except as necessary to
               reflect any stock split, stock dividend or subdivision of the
               Common Stock of the Corporation), except as approved by a

               Directors; and

                    (D) Neither such Interested Shareholder nor any of its
               Affiliates shall have become the beneficial owner of any
               additional shares of Capital Stock or securities convertible into
               Capital Stock except as part of the transaction that results in
               such Interested Shareholder becoming an Interested Shareholder
               and except in a transaction that, after giving effect thereto,
               would not result in any increase in the percentage beneficial
               ownership of the Interested Shareholder or any of its Affiliates
               of any class or series of Capital Stock.

               (v) A proxy or information statement describing the proposed

     The purpose for which the Corporation is organized is to transact any and
all lawful business for which corporations may be incorporated under the Texas
Business Corporation Act (the "TBCA").

                                   ARTICLE IV

     The total number of shares of all classes of stock which the Corporation
shall have authority to issue is 250,000,000 which shall be divided into (a)
200,000,000 shares of common stock having a par value of $.001 per share

including voting rights of the various classes of stock are as follows:

     1.   Preferred Stock.  The shares of Preferred Stock may be divided into
and issued in series.  The board of directors shall have the authority to
establish series of unissued shares of Preferred Stock by fixing and determining
the relative rights and preferences of the shares of any series so established,
and to increase or decrease the number of shares within each such series;
provided, however, that the board of directors may not decrease the number of
shares within a series of Preferred Stock to less than the number of shares
within such series that are then issued.  The Preferred Stock of each such
series shall have such designations, preferences, limitations or relative
rights, including voting rights, as shall be set forth in the resolution or
resolutions establishing such series adopted by the board of directors,
including, but without limiting the generality of the foregoing, the following:

          (a) the distinctive designation of, and the number of shares of
     Preferred Stock that shall constitute, such series, which number (except
     where otherwise provided by the board of directors in the resolution
     establishing such series) may be increased or decreased (but not below the
     number of shares of such series then outstanding) from time to time by like
     action of the board of directors;

          (b) The rights in respect of dividends, if any, of such series of
     Preferred Stock, the extent of the preference or relation, if any, of such
     dividends to the dividends payable on any other class or classes or any
     other series of the same or other class or classes of capital stock of the
     Corporation and whether such dividends shall be cumulative or
     noncumulative;

          (c) The right, if any, of the holders of such series of Preferred
     Stock to convert the same into, or exchange the same for, shares of any
     other class or classes or of any other series of the same or any other
     class or classes of capital stock, obligations, indebtedness, rights to
     purchase securities or other securities of the Corporation or other
     entities, domestic or foreign, or for other property or for any combination
     of the foregoing, and the terms and conditions of such conversion or
     exchange;

     subject to redemption, and the redemption price or prices and the time or
     times at which, and the terms and conditions on which, shares of such
     series of Preferred Stock may be redeemed;

          (e) The rights, if any, of the holders of such series of Preferred
     Stock upon the voluntary or involuntary liquidation, dissolution or
     winding-up of the Corporation or in the event of any merger or
     consolidation of or sale of assets by the Corporation;

          (f) The terms of any sinking fund or redemption or repurchase or
     purchase account, if any, to be provided for shares of such series of
     Preferred Stock;

          (g) The voting powers, if any, of the holders of any series of
     Preferred Stock generally or with respect to any particular matter, which
     may be less than, equal to or greater than one vote per share, and which
     may, without limiting the generality of the foregoing, include the right,
     voting as a series of Preferred Stock as a class, to elect one or more
     directors of the Corporation generally or under such specific circumstances
     and on such conditions, as shall be provided in the resolution or
     resolutions of the board of directors adopted pursuant hereto, including,
     without limitation, in the event there shall have been a default in the
     payment of dividends on or redemption of any one or more series of
     Preferred Stock; and

          (h) Such other powers, preferences and relative, participating,
     optional and other special rights, and the qualifications, limitations and
     restrictions thereof, as the board of directors shall determine.

     2.   Common Stock.

          (i) Subject to the prior and superior rights of the Preferred Stock,
and on the conditions set forth in Section 1 of this Article or in any
resolution of the board of directors providing for the issuance of any series of
Preferred Stock, and not otherwise, such dividends (payable in cash, stock or
otherwise) as may be determined by the board of directors may be declared and
paid on the Common Stock from time to time out of any funds legally available
therefor.

          (j) Each holder of Common Stock shall be entitled to one vote for each
share held.

     3.   Cumulative Voting Denied.  Shares of the voting stock of the
Corporation shall not be voted cumulatively.

     4.   Preemptive Rights.  Except as may be established by the board of
directors with respect to any series of Preferred Stock, shares of stock of the
Corporation do not carry preemptive rights.

     5.   Stock Certificates.  There shall be set forth on the face or back of
each certificate for shares of stock of the Corporation a statement that each of
the following is set forth in the articles of incorporation of the Corporation
on file in the Office of the Secretary of State of the State of Texas, and that
the Corporation will furnish a copy of each such statement to the record holder
of the certificate without charge on written request to the Corporation at its
principal place of business or registered office: (i) a statement of the
designations, preferences, and relative rights, including voting rights, of each
class or series of the Corporation's capital stock to the extent that they have
been fixed and determined; (ii) a statement of the authority of the board of
directors to fix and determine the designations, preferences, limitations and
relative rights, including voting rights, of any series; and (iii) a statement
of the extent to which the Corporation has by its articles of incorporation
limited or denied the preemptive right of shareholders to acquire unissued or
treasury shares of the Corporation.

     6.   Reverse Stock Split.  At 5:00 p.m. Houston Time on September 26, 1997
(the "Effective Date"), each share of the Company's Common Stock, par value
$.001 per share, issued and outstanding (the "Old Common Stock") shall
automatically and without any action on the part of the holder thereof be
reclassified and changed into two-fifths of a share of the Company's Common
Stock, par value $.001 per share (the "New Common Stock"), subject to the
treatment of fractional share interests as described below.  Each holder of a
certificate or certificates, which immediately prior to the Effective Date
represented outstanding shares of Old Common Stock (the "Old Certificates,"
whether one or more), shall be entitled to receive, upon surrender of such Old
Certificates to the Company's exchange agent appointed by the Company (the
"Exchange Agent") for cancellation, a certificate or certificates (the "New
Certificates," whether one or more) representing the number of whole shares of
the New Common Stock into which and for which the shares of the Old Common Stock
formerly represented by such Old Certificates so surrendered are reclassified
under the terms hereof.  From and after the Effective Date, Old Certificates
shall represent only the right to receive New Certificates (and, where
applicable, cash in lieu of fractional shares, as provided below) pursuant to
the provisions hereof.  No certificates or scrip representing fractional share
interests in New Common Stock will be issued, and no such fractional share
interest will entitle the holder thereof to vote, or to any rights of a
shareholder of the Company.  A holder of Old Certificates shall receive, in lieu
of any fraction of a share of New Common Stock to which the holder would
otherwise be entitled, a cash payment equal to the product of such fraction
multiplied by $16.00. If more than one Old Certificate shall be surrendered at
one time for the account of the same shareholder, the number of full shares of
New Common Stock for which New Certificates shall be issued shall be computed on
the basis of the aggregate number of shares represented by the Old Certificates
so surrendered. In the event that the Company's Exchange Agent determines that a
holder of Old Certificates has not tendered to all his certificates for exchange
the Exchange Agent shall carry forward any fractional share until all
certificates of that holder have been presented for exchange such that payment
for fractional shares to any one person shall not exceed $16.00. If any New
Certificate is to be issued in a name other than that in which the Old
Certificates surrendered for exchange are issued, the Old Certificates so
surrendered shall be properly endorsed and otherwise in proper form for
transfer, and the person or persons requesting such exchange shall affix any
requisite stock transfer tax stamps to the Old Certificates so surrendered, or
provide funds for their purchase, or establish to the satisfaction of the
Exchange Agent that such taxes are not payable. From and after the Effective
Date the amount of capital represented by the shares of the New Common Stock
into which and for which the shares of Old Common Stock are reclassified under
the terms hereof shall be the same as the amount of capital represented by the
shares of Old Common Stock so reclassified, until thereafter reduced or
increased in accordance with applicable law. The Exchange Agent shall be the
Secretary of the Company or such other agent as the Company may appoint for such
purpose.

                                   ARTICLE V

                  INITIAL CONSIDERATION FOR ISSUANCE OF SHARES

     The Corporation will not commence business until it has received for the
issuance of its shares consideration of a value of at least One Thousand and
No/100 Dollars ($1,000.00), consisting of money, labor done or property actually
received.

                                   ARTICLE VI

BOARD OF DIRECTORS

     (1) The property, affairs and business of the Corporation shall be managed
by or under the direction of the Corporation's board of directors.  Subject to
the rights of the holders of any series of Preferred Stock, the number of
directors constituting the board of directors of the Corporation shall not be
less than nine (9) nor more than eighteen (18).  Subject to the rights of the
holders of any series of Preferred Stock, the number of directors shall be
determined from time to time hereafter exclusively pursuant to a resolution
adopted by the affirmative vote of a majority of the entire board of directors.
For purposes of these Restated Articles of Incorporation, the "entire board of
directors" shall mean the number of directors that would be in office if there
were no vacancies nor any unfilled newly created directorships. Directors need
not be residents of the State of Texas or shareholders of the Corporation. Until
the third annual meeting of shareholders following effectiveness of these
Restated Articles of Incorporation under the TBCA, the directors shall be
divided into three classes, which shall consist, as nearly as possible, of one-
third of the total number of directors constituting the entire Board of
Directors, and designated Class I, Class II and Class III, respectively. Each
director elected or appointed prior to the effectiveness of these Restated
Articles of Incorporation under the TBCA shall serve for their full term, such
that the term of each Class I director shall end at the second succeeding annual
meeting of shareholders following effectiveness of these Restated Articles of
Incorporation, the term of each Class II director shall end at the third
succeeding annual meeting of shareholders following effectiveness of these
Restated Articles of Incorporation, and the term of each Class III director
shall end at the first succeeding annual meeting of shareholders following
effectiveness of these Restated Articles of Incorporation. The term of each
director elected after the effectiveness of these Restated Articles of
Incorporation whether at an annual meeting or to fill a vacancy in the board of
directors arising for any reason, including any increase in the size of the
board of directors, shall end at the first annual meeting following his or her
election. Commencing with the third annual meeting of shareholders following the
effectiveness of these Restated Articles of Incorporation, the foregoing
classification of the board of directors shall cease, and all directors shall be
of one class and serve for a term ending at the annual meeting following the
annual meeting at which the director was elected. In no case shall a decrease in
the number of directors shorten the term of any incumbent director. Each
director shall hold office after the annual meeting at which his or her term is
scheduled to end until his or her successor shall be elected and shall qualify,
subject, however, to prior death, resignation, disqualification or removal from
office in accordance with the TBCA. Any newly created directorship resulting
from an increase in the number of directors may be filled by a majority of the
board of directors then in office, provided that a quorum is present, and any
other vacancy on the board of directors may be filled by a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director.

     (2) Notwithstanding anything else contained in these Restated Articles of
Incorporation, whenever holders of any one or more series of Preferred Stock
shall have the right, voting separately

by class or series, to elect directors at any annual or special meeting of
shareholders, the election, term of office, filling of vacancies and other
features of such directorships shall be governed by the provisions applicable to
such class or series established pursuant to Paragraph 1 of Article IV hereof.
Directors shall be elected by such holders annually unless expressly provided
otherwise by the terms of such class or series of Preferred Stock.

     (3) No director of the Corporation shall be removed from office as a
director by vote or other action of the shareholders or otherwise except for
cause.

                                  ARTICLE VIII

                        LIMITATION OF DIRECTOR LIABILITY

     To the greatest extent permitted by applicable law in effect from time to
time, a director of the Corporation shall not be liable to the Corporation or
its shareholders for monetary damages for an act or omission in the director's
capacity as a director except for liability for: (i) a breach of a director's
duty of loyalty to the Corporation or its shareholders; (ii) an act or omission
not in good faith that constitutes a breach of duty of the director to the
Corporation or that involved intentional misconduct or a knowing violation of
the law; (iii) a transaction from which a director received an improper benefit,
whether or not the benefit resulted from an action taken within the scope of the
director's office; (iv) an act or omission for which the liability of a director
is expressly provided for by statute; or (v) an act related to any unlawful
stock repurchase or unlawful payment of a dividend.

                                   ARTICLE IX

                                INDEMNIFICATION

     1.   Right to Indemnification.  Each person who was or is made a party or
is threatened to be made a party to or is otherwise involved in any threatened,
pending or completed action, suit or proceeding whether civil, criminal,
administrative, arbitrative or investigative, any appeal in such action, suit or
proceeding, and any inquiry or investigation that would lead to such action,
suit or proceeding (hereinafter a "proceeding"), by reason of the fact that he
or she, or a person of whom he or she is the legal representative, is or was a
director or officer of the Corporation or is or was serving at the request of
the Corporation as a director or officer of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to any employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a director
or officer or in any other capacity while serving as a director or officer,
shall be indemnified and held harmless by the Corporation to the fullest extent
authorized by the TBCA, as the same exists or may hereafter be amended (but, in
the case of any such amendment, only to the extent that such amendment permits
the Corporation to provide broader indemnification rights than permitted prior
thereto), against all judgments, fines, penalties (including excise tax and
similar taxes), settlements, and reasonable expenses actually incurred by such
indemnitee in connection therewith.  The right to indemnification conferred in
this Article shall include the right to be paid by the Corporation the expenses
incurred in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that if the TBCA
requires, an advancement of expenses incurred by an indemnitee shall be made
only upon delivery to the Corporation of any undertaking, by or on behalf of
such indemnitee, to repay all amount so advanced if it shall ultimately be
determined by that such indemnitee is not entitled to be indemnified for such
expenses under this Article or otherwise.

     2.   Insurance.  The Corporation may purchase and maintain insurance, at
its expense, on behalf of any indemnitee against any liability asserted against
him and incurred by him in such a capacity or arising out of his status as a
representative of the Corporation, whether or not the Corporation would have the
power to indemnify such person against such expense, liability or loss under the
TBCA.

     3.   Indemnity of Employees and Agents of the Corporation.  The Corporation
may, to the extent authorized from time to time by the board of directors, grant
rights to indemnification and to the advancement of expenses to any employee or
agent of the Corporation to the fullest extent of the provisions of this article
or as otherwise permitted under the TBCA with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

     Special meetings of the Corporation's shareholders may be called (i) by the
president, the board of directors, or such other person or persons as may be

                                   ARTICLE XI

                              AMENDMENT OF BYLAWS

     In furtherance and not in limitation of the powers conferred by the laws of
the State of Texas, the board of directors is expressly authorized to alter,
amend or repeal the bylaws of the Corporation or to adopt new bylaws.

                                  ARTICLE XII

                 PROVISIONS APPLICABLE TO BUSINESS COMBINATIONS

     1.   Vote Required for Certain Business Combinations.  In addition to any
affirmative vote required by law or these Articles of Incorporation or the
Bylaws of the Corporation, and except as otherwise expressly provided in Section
2 of this Article XII, a Business Combination (as hereinafter defined) with, or
proposed by or on behalf of, any Interested Shareholder (as hereinafter defined)
or any Affiliate or Associate (as hereinafter defined) of any Interested
Shareholder or any person who thereafter would be an Affiliate or Associate of
such Interested Shareholder, shall require the affirmative vote of not less than
eighty percent (80%) of the votes entitled to be cast by the holders of all of
the then outstanding shares of Voting Stock (as hereinafter defined), voting
together as a single class, and the affirmative vote of not less than a majority
of the votes entitled to be cast by the Voting Stock beneficially owned by
persons other than such Interested Shareholder. Each share of Voting Stock shall
have the number of votes granted to it in, or duly fixed by the board of
directors pursuant to, Article IV of these Articles of Incorporation.  Such
affirmative vote shall be required notwithstanding the fact that no vote may be
required, or that a lesser percentage or separate class vote may be specified,
by law, or in any agreement of the Corporation with any national securities
exchange or otherwise.

     2.   Exceptions to Higher Vote Requirement.  The provisions of Section 3 of
this Article XII shall not be applicable to any particular Business Combination,
and such Business Combination shall require only such affirmative vote, if any,
as is required by law or by any other provision of these Articles of
Incorporation or the Bylaws of the Corporation, or any agreement with any
national securities exchange, if all of the conditions specified in any of the
following Paragraphs (a), (b) or (c) are met or, in the case of a Business
Combination not involving the payment of consideration to the holders of the
Corporation's outstanding Capital Stock (as hereinafter defined), if the
condition specified in the following Paragraph (a) is met:

          (a)     The Business Combination shall have been approved either
     specifically, or as a transaction which is within a series of related
     transactions described with reasonable specificity, by at least an eighty
     percent (80%) vote of the Continuing Directors (as hereinafter defined),
     who shall at the time constitute at least a majority of the Whole Board (as
     hereinafter defined) (whether or not such approval occurs prior to or
     subsequent to the acquisition of, or announcement or public disclosure of
     the intention to acquire, beneficial ownership of the Voting Stock that
     caused the Interested Shareholder to become an Interested Shareholder).

          (b) All of the following conditions shall have been met:

                                       17

               (i) The aggregate amount of cash and the Fair Market Value (as
          hereinafter defined), as of the date of the consummation of the
          Business Combination, of consideration other than cash to be received
          per share by holders of Common Stock of the Corporation in such
          Business Combination shall be at least equal to the higher amount

               any brokerage commissions, transfer taxes and soliciting dealers'
               fees) ("Highest Purchase Price") paid by or on behalf of the
               Interested Shareholder for any share of Common Stock in
               connection with the acquisition by the Interested Shareholder of
               beneficial ownership of shares of Common Stock,

                         (x) within the two-year period immediately prior to the
                    first public announcement of the proposed Business
                    Combination (the "Announcement Date"), or

                         (y) in the transaction in which it became an Interested
                    Shareholder,

               whichever is higher, in either case, as adjusted for any
               subsequent stock split, stock dividend, subdivision or
               reclassification with respect to the Common Stock; provided that
               if the Business Combination is effected more than 180 days after
               the last date upon which such Interested Shareholder paid the
               Highest Purchase Price, then the consideration to be received by
               the shareholders shall be increased by Interest (as hereinafter
               defined) with respect to the period from the date the Interested
               Shareholder paid the applicable Highest Purchase Price to the
               effective date of the Business Combination ("Adjustment Period").

                    (B) The Fair Market Value per share of Common Stock on the
               Announcement Date or on the date (the "Determination Date") on
               which the Interested Shareholder became an Interested
               Shareholder, whichever is higher, as adjusted for any subsequent
               stock split, stock dividend, subdivision or reclassification with
               respect to the Common Stock.

               (ii) The aggregate amount of cash and the Fair Market Value, as
          of the date of the consummation of the Business Combination, of
          consideration other than cash to be received per share by holders of
          shares of any class or series of outstanding Capital Stock, other than
          Common Stock, shall be at least equal to the highest amount determined

               or series of Capital Stock in connection with the acquisition by
               the Interested Shareholder of beneficial ownership of shares of
               such class or series of Capital Stock,

                         (x) within the two-year period immediately prior to the
                    Announcement Date, or

                         (y)    in the transaction in which it became an

               Stock; provided that if the Business Combination is effected more
               than 180 days after the last date upon which such Interested
               Shareholder paid the Highest Purchase Price, then the
               consideration to be received by the

                                       18
<PAGE>

               Directors; and

               additional shares of Capital Stock or securities convertible into
               Capital Stock except as part of the transaction that results in
               such Interested Shareholder becoming an Interested Shareholder
               and except in a transaction that, after giving effect thereto,
               would not result in any increase in the percentage beneficial
               ownership of the Interested Shareholder or any of its Affiliates
               of any class or series of Capital Stock.

quarterly dividend period shall be paid in cash, out of funds legally available
therefor.

     (d) In the event a Change of Control occurs prior to the fifth anniversary
of the Original Issuance Date, the holders of the outstanding shares of
Convertible Preferred Stock, as of the close of business on the Business Day
immediately preceding the date of consummation of the Change of Control, shall
be entitled to receive, out of funds legally available therefor, all accrued or
accumulated and unpaid dividends as of the date of the consummation of such
Change of Control and the lesser of (i) all dividends that would accrue from the
date of the consummation of such Change of Control through the fifth anniversary
of the Original Issuance Date and (ii) all dividends that would accrue from the
date of the consummation of such Change of Control through the date that is two
and one-half (2 1/2) years from the date of the consummation of the Change of
Control, such dividends to be paid in cash, provided that, any holder of
Convertible Preferred Stock who converts such shares into shares of Common Stock
pursuant to Section 4 hereof after receipt of a notice from the Corporation
pursuant to Section 6 hereof and prior to the date of consummation of the Change
of Control to which such notice relates, may elect to receive the sum payable
pursuant to this paragraph in the form of cash, shares of Common Stock or any
combination thereof, all as specified in such holder's notice of election to
convert. Shares of Common Stock issued pursuant to the foregoing election shall
be valued at the Fair Market Value as of the date of consummation of the Change
of Control. Any holder of Convertible Preferred Stock who elects to require the
Company to redeem the Convertible Preferred Stock upon a Change of Control in
accordance with Section 6 hereof, shall be entitled to receive an amount equal
to the amount of such dividends, in cash, as part of the amount paid for such
redemption under Section 6(a). Payment of the amount specified in clauses (i)
and (ii) in accordance with this Section shall satisfy in full the obligation of
the Corporation to otherwise make such dividend payments on the scheduled
Preferred Dividend Payment Dates.

     (e) The dividends payable with respect to the Convertible Preferred Stock
on each Preferred Dividend Payment Date pursuant to Sections 2(a) through (c)
shall be paid to the holders of shares of the Convertible Preferred Stock as
they appear on the stock records of the Corporation on such date (the "Preferred
Record Date") as shall be fixed by the Board, which Preferred Record Date shall
not be more than 40 days prior to the

                                       2
<PAGE>

applicable Preferred Dividend Payment Date and shall not precede the date upon
which the resolution fixing such Preferred Record Date is adopted.

     (f) Except as otherwise provided herein, if at any time the Corporation
pays less than the total amount of dividends then accrued or accumulated with
respect to the Convertible Preferred Stock, such payment shall be distributed
ratably among the holders of the shares of Convertible Preferred Stock based
upon the number of shares of Convertible Preferred Stock then held by each
holder.

     (g) In addition to all dividends payable pursuant to Sections 2(a) through
(d), whenever the Corporation shall declare any dividend on its Common Stock
(other than a distribution described in Section 4(e)(5) or a dividend described
in Section 4(e)(11) (a "Common Dividend")), the holders of the outstanding
shares of Convertible Preferred Stock shall have the option, exercisable by the
Requisite Convertible Preferred Shareholders to (i) participate in such
dividends on a ratable basis with such Common Stock, pro rata in accordance with
the number of shares of Common Stock into which such shares of Convertible
Preferred Stock are then convertible (the "Cash Election"), or (ii) reduce the
Conversion Price then in effect by the amount of dividends payable with respect
to one share of Common Stock or, if not payable in cash, by an amount equal to
the Fair Market Value of such dividends. The Corporation shall notify each
holder of Convertible Preferred Stock within two Business Days following the
date on which the Board declares a Common Dividend, which notice shall specify
the amount of such dividend per share of such Common Stock. If the Corporation
shall have received, prior to the 10th day following the date of such notice
from the Corporation (the "Determination Date"), notices from the Requisite
Preferred Shareholders electing the Cash Election, then the holders of record of
Convertible Preferred Stock as of the Determination Date shall be entitled to
receive, out of funds legally available therefor, the Common Dividend in
accordance with clause (i). Any such dividend shall be payable no later than 10
Business Days after the Determination Date. Unless a Cash Election has been made
prior to the Determination Date, the adjustment to the Conversion Price
specified in clause (ii) shall become effective as of the close of the business
on the Determination Date.

     3. LIQUIDATION.

     Upon a Liquidation, after payment or provision for payment of the debts and
other liabilities of the Corporation and the liquidation preference of any class
or series of capital stock of the Corporation ranking senior to the Convertible
Preferred Stock, the holders of Convertible Preferred Stock shall be entitled to
receive, out of the remaining assets of the Corporation available for
distribution to its shareholders, with respect to each share of Convertible
Preferred Stock, an amount equal to the greater of (i) the Liquidation Amount of
such share and (ii) the amount the holder of such share would have received if
such holder had converted such share of Convertible Preferred Stock into shares
of Common Stock immediately prior to such Liquidation, before any distribution
shall be made to the holders of the Common Stock or any other class or series of
capital stock of the Corporation ranking junior to the Convertible Preferred
Stock. If upon any Liquidation the assets of the Corporation available for
distribution to its shareholders shall be insufficient to pay the holders of
Convertible Preferred Stock the full

                                       3
<PAGE>

amount to which they shall be entitled, the holders of Convertible Preferred
Stock shall share in any distribution of assets pro rata in accordance with the
total amount that each such holder would have received had there been such
sufficient assets.

     4.  CONVERSION.

     (a) Upon the terms set forth in this Section 4, each holder of shares of
Convertible Preferred Stock shall have the right, at such holder's option, at
any time and from time to time, to convert all or any portion of such shares
into the number of fully paid and nonassessable shares of Common Stock equal to
the quotient obtained by dividing (A) the aggregate Liquidation Amount of the
shares of Convertible Preferred Stock to be converted by (B) the Conversion
Price (as defined below), as last adjusted and then in effect, by surrender of
the certificate or certificates representing such shares in accordance with this
Section 4. The initial conversion price per share at which shares of Common
Stock shall be issuable upon conversion of shares of Convertible Preferred Stock
(the "Conversion Price") shall be $14.00, subject to adjustment as set forth
herein.

     (b) Any holder of shares of Convertible Preferred Stock electing to convert
all or any portion of the shares in accordance with Section 4(a) above shall
give written notice to the Corporation as specified herein (which notice may be
given by facsimile transmission) that such holder elects to convert the same and
shall state therein the number of shares of Convertible Preferred Stock to be
converted and the name or names in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued. Promptly thereafter, the
holder shall surrender the certificate or certificates representing the shares
of Convertible Preferred Stock to be converted, duly endorsed, at the office of
the Corporation or any transfer agent for such shares, or at such other place
designated by the Corporation, provided that the Corporation shall at all times
maintain an office or agency for such purposes. The Corporation shall, promptly
upon receipt of such notice, issue and deliver to or upon the order of such
holder, against delivery of the certificates representing the shares of
Convertible Preferred Stock that have been converted, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled (in the number(s) and denomination(s) designated by such holder),
and the Corporation shall deliver to such holder a certificate or certificates
for the number of shares of Convertible Preferred Stock that such holder has not
elected to convert. To the extent the holder requests that the shares of Common
Stock to be issued upon conversion shall be issued in the name of any Person
other than the holder of the Convertible Preferred Stock surrendered for
conversion, such holder shall deliver to the Corporation (and its transfer
agent, if applicable) such documents and certificates, including, if requested,
an opinion of counsel to the effect that the transfer thereof will not
constitute a violation of the Securities Act of 1933, as amended, or state
securities laws. The Corporation shall pay any documentary, stamp or similar
issue or transfer tax due on the issuance of Common Stock upon the conversion of
Convertible Preferred Stock or due on the issuance of a new certificate or
certificates for any Convertible Preferred Stock not converted, other than any
tax in respect of any transfer involved in any issuance of shares of Common
Stock in a name other than the name in which the shares of Convertible Preferred
Stock so converted were registered. The conversion right

                                       4
<PAGE>

with respect to any shares of Convertible Preferred Stock shall be deemed to
have been exercised at the earliest date upon which both the notice of
conversion referred to in the first sentence of this paragraph and the
certificates therefor shall have been so delivered (the "Conversion Date") and
the Person or persons entitled to receive the Common Stock issuable upon
conversion shall be treated for all purposes as the record holder or holders of
such Common Stock upon that date.

     (c) No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Convertible Preferred Stock. The number of full shares
of Common Stock issuable upon conversion of Convertible Preferred Stock shall be
computed on the basis of the aggregate number of shares of such Convertible
Preferred Stock to be converted. Instead of any fractional shares of Common
Stock that would otherwise be issuable upon conversion of any such shares, the
Corporation shall pay a cash adjustment in respect of such fractional interest
in an amount equal to the product of (i) the Fair Market Value of one share of
Common Stock and (ii) such fractional interest. The holders of fractional
interests shall not be entitled to any rights as shareholders of the Corporation
in respect of such fractional interests.

     (d) The Corporation shall reserve out of its authorized but unissued Common
Stock a sufficient number of shares of Common Stock to permit the conversion of
all of the then-outstanding shares of Convertible Preferred Stock. For the
purposes of this Section 4(d), the full number of shares of Common Stock then
issuable upon the conversion of all then-outstanding shares of Convertible
Preferred Stock shall be computed as if at the time of computation all
outstanding shares of Convertible Preferred Stock were held by a single holder.
The Corporation shall from time to time, in accordance with the laws of the
State of Texas and its articles of incorporation, increase the authorized amount
of its Common Stock if at any time the authorized amount of its Common Stock
remaining unissued shall not be sufficient to permit the conversion of all
shares of Convertible Preferred Stock at the time outstanding. All shares of
Common Stock issued upon conversion of the shares of Convertible Preferred Stock
shall be validly issued, fully paid and nonassessable.

     (e) The Conversion Price shall be subject to adjustment from time to time
as follows:

          (1) If the Corporation shall, (A) at any time or from time to time
     after the Original Issuance Date through the date that is two and one-half
     (2 1/2) years after the Original Issuance Date, issue any shares of Common
     Stock, 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, other than Excluded Stock, without
     consideration or for a consideration per share less than the greater of
     (x) the Conversion Price or (y) the Fair Market Value of the Common Stock,
     in effect immediately prior to the issuance of such Common Stock or
     securities, or (B) at any time or from time to time after the date that is
     two and one-half (2 1/2) years after the Original Issuance Date, issue any
     shares of Common Stock, options to purchase or rights to subscribe for
     Common Stock,

                                       5
<PAGE>

     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, other than Excluded Stock, without
     consideration or for a consideration per share less than the Fair Market
     Value of the Common Stock, in effect immediately prior to the issuance of
     such Common Stock or securities, then such Conversion Price, as in effect
     immediately prior to each such issuance, shall forthwith be lowered to a
     price equal to the price obtained by multiplying:

                (A) the Conversion Price at which shares of Convertible
          Preferred Stock were theretofore convertible by

                (B) a fraction of which (x) the denominator shall be the number
          of shares of Common Stock outstanding on a fully-diluted basis
          immediately after such issuance and (y) the numerator shall be the sum
          of (1) the number of shares of Common Stock outstanding on a fully-
          diluted basis immediately prior to the date of such issuance and
          (2) the number of additional shares of Common Stock which the
          aggregate offering price of the number of shares of Common Stock so
          offered would purchase at the greater of the Conversion Price or the
          Fair Market Value per share of Common Stock.

          (2) If the Corporation shall, at any time or from time to time after
     the Original Issuance Date, directly or indirectly, redeem, purchase or
     otherwise acquire any shares of Common Stock, 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, for a
     consideration per share greater than the Fair Market Value (plus, in the
     case of such options, rights, or securities, the additional consideration
     required to be paid to the Corporation upon exercise, conversion or
     exchange) for shares of Common Stock in effect immediately prior to such
     event, then such Conversion Price, as in effect immediately prior to each
     such event, shall forthwith be lowered to a price equal to the price
     obtained by multiplying:

                (A) the Conversion Price at which shares of Convertible
          Preferred Stock were theretofore convertible by

                (B) a fraction of which (x) the denominator shall be the Fair
          Market Value per share of Common Stock immediately prior to such event
          and (y) the numerator shall be the result of dividing:

                       i) (1) the product of the number of shares of Common
                Stock outstanding on a fully-diluted basis and the Fair Market
                Value per share of Common Stock, in each case immediately prior
                to such event, minus (2) the aggregate consideration paid by the
                Corporation in such event (plus, in the case of such options,
                rights, or convertible or exchangeable securities, the aggregate

                                       6
<PAGE>

                additional consideration to be paid by the Corporation upon
                exercise, conversion or exchange), by

                       ii) the number of shares of Common Stock outstanding on a
                fully-diluted basis immediately after such redemption.

          (3) For the purposes of any adjustment of the Conversion Price
     pursuant to Sections 4(e)(1) or (2) above, the following provisions shall
     be applicable:

                (A) In the case of the issuance of Common Stock for cash in a
          public offering or private placement, the consideration shall be
          deemed to be the amount of cash paid therefor by the investors without
          deducting any discounts, commissions or placement fees payable by the
          Corporation to any underwriter or placement agent in connection with
          the issuance and sale thereof that are usual and customary for such a
          transaction. Notwithstanding anything provided above to the contrary,
          for purposes of issuances described in this clause, Fair Market Value
          for such issuance shall be deemed to be the lesser of (i) the Closing
          Price on the date of the execution of the underwriting, placement,
          subscription or purchase agreement executed in connection with such
          offering or placement and (ii) the Fair Market Value (as defined
          herein) determined as of the date of the execution of the
          underwriting, placement, subscription or purchase agreement executed
          in connection with such offering or placement.

                (B) In the case of the issuance of Common Stock for
          consideration consisting in whole or in part other than cash, the
          value of such non-cash consideration shall be deemed to be the fair
          market value thereof as determined in good faith by the Board or a
          duly authorized committee thereof, irrespective of any accounting
          treatment. Notwithstanding anything provided above to the contrary,
          for purposes of issuances described in this clause, Fair Market Value
          for such issuance shall be deemed to be the fair market value as
          determined in good faith by the Board or a duly authorized committee
          thereof, irrespective of any accounting treatment, as of the date of
          the approval of such transaction by the Board or appropriate committee
          of the Board.

                (C) In the case of the issuance of 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,
          except for options to acquire Excluded Stock:

                       i) the aggregate maximum number of shares of Common Stock
                deliverable upon exercise 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
                consideration equal to the consideration (determined in the
                manner provided in Sections 4(e)(3)(A) and (B) above), if any,
                received by the Corporation upon the issuance of such options
                or

                                       7
<PAGE>

                rights were issued and for a consideration equal to the
                consideration (determined in the manner provided in Sections
                4(e)(3)(A) and (B) above), if any, received by the Corporation
                upon the issuance of such options or rights plus the minimum
                purchase price provided in such options or rights for the Common
                Stock covered thereby;

                       ii) the aggregate maximum number of shares of Common
                Stock deliverable upon conversion of or in exchange for any such
                convertible or exchangeable securities or upon the exercise of
                options to purchase or rights to subscribe for such convertible
                or exchangeable securities and subsequent conversion or exchange
                thereof shall be deemed to have been issued at the time such
                securities, options, or rights were issued and for a
                consideration equal to the consideration received by the
                Corporation for any such securities and related options 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 Corporation upon
                the conversion or exchange of such securities or the exercise of
                any related options or rights (the consideration in each case to
                be determined in the manner provided in Sections 4(e)(3)(A) and
                (B) above); and

                       iii) on any change in the number of shares or exercise
                price of Common Stock deliverable upon exercise of any such
                options or rights or conversions of or exchanges for such
                securities, other than a change resulting from the antidilution
                provisions thereof, the applicable Conversion Price shall
                forthwith be readjusted to such Conversion Price as would have
                been obtained had the adjustment made upon the issuance of such
                options, rights or securities not converted prior to such change
                or options or rights related to such securities not converted
                prior to such change been made upon the basis of such change;

                       iv) Upon the expiration of the right to convert, exchange
                or acquire Common Stock in accordance with the terms of any
                securities, the issuance of which securities had effected an
                adjustment to the Conversion Price pursuant to the terms of this
                Section 4(e), if any such securities shall not have been
                converted, exercised or exchanged prior to such expiration, the
                number of shares of Common Stock deemed to have been issued and
                outstanding by reason of the fact that they were issuable upon
                conversion, exchange or exercise of any such security pursuant
                to Section 4(e)(l)

                                       8
<PAGE>

                above, shall no longer be computed as set forth above and the
                Conversion Price shall forthwith be readjusted and thereafter be
                the price at which it would have been had the adjustment to the
                Conversion Price made upon the issuance or sale of any such
                security been made on the basis of the issuance only of the
                number of additional shares of Common Stock actually issued upon
                exercise, conversion or exchange thereof and thereupon only the
                number of additional shares of Common Stock actually so issued
                shall be deemed to have been issued and the only consideration
                actually received by the Corporation (computed as set forth
                above) shall be deemed to have been received by the Corporation;
                and

                       v) No further adjustment of the Conversion Price adjusted
                upon the issuance of any such options, rights, convertible
                securities or exchangeable securities shall be made as a result
                of the actual issuance of Common Stock on the exercise of any
                such rights or options or any conversion or exchange of any such
                securities.

          (4) All calculations under this Section will be made to the nearest
     one-hundredth of a cent or to the nearest whole share, as the case may be.
     No adjustment to the Conversion Price will be required unless such
     adjustment would result in an increase or decrease of at least one percent
     (1%) of the Conversion Price; provided, however, that any adjustments which
     by reason of this clause (4) are not required to be made will be carried
     forward and taken into account in a subsequent adjustment, if any.

          (5) If, at any time after the Original Issuance Date, the number of
     shares of Common Stock outstanding is increased by a stock dividend payable
     in shares of Common Stock or by a subdivision or split-up of shares of
     Common Stock, then the provisions of Section 4(e)(1) shall not apply and,
     following the record date for the determination of holders of Common Stock
     entitled to receive such stock dividend, subdivision or split-up, the
     Conversion Price shall be appropriately decreased so that the number of
     shares of Common Stock issuable on conversion of each share of Convertible
     Preferred Stock shall be increased in proportion to such increase in
     outstanding shares.

          (6) If, at any time after the Original Issuance Date, the number of
     shares of Common Stock outstanding is decreased by a combination of the
     outstanding shares of Common Stock, then, following the record date for
     such combination, the Conversion Price shall be appropriately increased so
     that the number of shares of Common Stock issuable on conversion of each
     share of Convertible Preferred Stock shall be decreased in proportion to
     such decrease in outstanding shares.

                                       9
<PAGE>

          (7) In the event of any capital reorganization of the Corporation, any
     reclassification of the stock of the Corporation (other than a change in
     par value or from par value to no par value or from no par value to par
     value or as a result of a stock dividend or subdivision, split-up or
     combination of shares), or any consolidation or merger of the Corporation
     (other than the Merger), each share of Convertible Preferred Stock shall
     after such reorganization, reclassification, consolidation, or merger be
     convertible into the kind and number of shares of stock or other securities
     or property of the Corporation or of the corporation resulting from such
     consolidation or surviving such merger to which the holder of the number of
     shares of Common Stock deliverable (immediately prior to the time of such
     reorganization, reclassification, consolidation or merger) upon conversion
     of such share of Convertible Preferred Stock would have been entitled upon
     such reorganization, reclassification, consolidation or merger. The
     provisions of this clause shall similarly apply to successive
     reorganizations, reclassifications, consolidations, or mergers.

          (8) In any case in which the provisions of this Section 4(e) shall
     require that an adjustment shall become effective immediately after a
     record date of an event, the Corporation may defer until the occurrence of
     such event (1) issuing to the holder of any share of Convertible Preferred
     Stock converted after such record date and before the occurrence of such
     event the shares of capital stock issuable upon such conversion by reason
     of the adjustment required by such event in addition to the shares of
     capital stock issuable upon such conversion before giving effect to such
     adjustments, and (2) paying to such holder any amount in cash in lieu of a
     fractional share of capital stock pursuant to Section 4(c) above; provided,
     however, that the Corporation shall deliver to such holder an appropriate
     instrument evidencing such holder's right to receive such additional shares
     and such cash.

          (9) Whenever a Conversion Price shall be adjusted as provided in this
     Section 4(e), the Corporation shall make available for inspection during
     regular business hours, at its principal executive offices or at such other
     place as may be designated by the Corporation, a statement, signed by its
     chief financial officer, showing in detail the facts requiring such
     adjustment and the Conversion Price that shall be in effect after such
     adjustment. The Corporation shall also cause a copy of such statement to be
     sent by first class certified mail, return receipt requested and postage
     prepaid, to each holder of Convertible Preferred Stock affected by the
     adjustment at such holder's address appearing on the Corporation's records.
     Where appropriate, such copy may be given in advance and may be included,
     as part of any notice required to be mailed under the provisions of this
     Section 4(e) below.

          (10) If the Corporation shall propose to take any action of the types
     described in clauses (5), (6) or (7) of this Section 4(e), the Corporation
     shall give notice to each holder of shares of Convertible Preferred Stock,
     in the manner set forth in clause (9) above, which notice shall specify the
     record date, if any, with respect to any such action and the date on which
     such action is to take place.

                                       10
<PAGE>

     Such notice shall also set forth such facts with respect thereto as shall
     be reasonably necessary to indicate the effect of such action (to the
     extent such effect may be known at the date of such notice) on the
     Conversion Price and the number, kind or class of shares or other
     securities or property which shall be deliverable or purchasable upon the
     occurrence of such action or deliverable upon conversion of shares of
     Convertible Preferred Stock. In the case of any action which would require
     the fixing of a record date, such notice shall be given at least 20 days
     prior to the date so fixed, and in case of all other action, such notice
     shall be given at least 30 days prior to the taking of such proposed
     action. Failure to give such notice, or any defect therein, shall not
     affect the legality or validity of any such action.

          (11) Without duplication of any other adjustment provided for in this
     Section 4, at any time the Corporation makes or fixes a record date for the
     determination of holders of Common Stock entitled to receive a dividend or
     other distribution payable in securities of the Corporation other than
     shares of Common Stock, provision shall be made so that each holder of
     Convertible Preferred Stock shall have the option to (i) receive as part of
     such dividend or distribution the number of securities of the Corporation
     which such holder would have received had its shares of Convertible
     Preferred Stock been converted into shares of Common Stock immediately
     prior to the date of such event or (ii) receive upon conversion thereof, in
     addition to the shares of Common Stock receivable thereupon, the number of
     securities of the Corporation which such holder would have received had its
     shares of Convertible Preferred Stock been converted into shares of Common
     Stock on the date of such event and had such holder thereafter, during the
     period from the date of such event to and including the date of conversion,
     retained such securities receivable by it pursuant to this paragraph during
     such period, subject to the sum of all other adjustments called for during
     such period under this Section 4 with respect to the rights of such holder
     of Convertible Preferred Stock.

          (12) If the Corporation issues any securities after the Original
     Issuance Date containing provisions protecting the holder or holders
     thereof against dilution in any manner more favorable to such holder or
     holders thereof than those set forth in this Section 4, such provisions
     (or any more favorable portion thereof) shall be deemed to be incorporated
     herein as if fully set forth in this Statement and, to the extent
     inconsistent with any provision of this Statement, shall be deemed to be
     substituted therefor.

     5. REDEMPTION AT OPTION OF THE CORPORATION.

          (a) The Corporation shall have the right to redeem, at any time after
     the fifth anniversary of the Original Issuance Date, out of funds legally
     available for such purpose, all, but not less than all, of the shares of
     Convertible Preferred Stock then outstanding, for an amount per share (the
     "Corporation Redemption Price"), which shall be payable in cash, as set
     forth below:

                                       11
<PAGE>

               (i) 103% of the Liquidation Amount, if such redemption occurs on
                   or after the fifth anniversary of the Original Issuance Date
                   and before the sixth anniversary date of the Original
                   Issuance Date;

               (ii) 102% of the Liquidation Amount, if such redemption occurs on
                    or after the sixth anniversary of the Original Issuance Date
                    and before the eighth anniversary date of the Original
                    Issuance Date; and

               (iii) 101% of the Liquidation Amount, if such redemption occurs
                     on or after the eighth anniversary of the Original Issuance
                     Date but prior to the Maturity Date.

          (b) Not less than 20 nor more than 60 days (such date as fixed by the
     Board of Directors of the Corporation is referred to herein as the
     "Redemption Record Date") prior to the date fixed for any redemption of
     shares of the Convertible Preferred Stock pursuant to this Section 5, a
     notice specifying the time and place of the redemption, the redemption
     price and the number of shares to be redeemed shall be given by first class
     mail, postage prepaid, to the holders of record on the Redemption Record
     Date of the shares of the Convertible Preferred Stock to be redeemed at
     their respective addresses as the same shall appear on the books of the
     Corporation, calling upon each holder of record to surrender to the
     Corporation on the redemption date at the place designated in the notice
     such holder's certificate or certificates representing the number of shares
     specified in the notice of redemption. Neither failure to mail such notice,
     nor any defect therein or in the mailing hereof, to any particular holder
     shall affect the sufficiency of the notice or the validity of the
     proceedings for redemption with respect to the other holders. Any notice
     mailed in the manner herein provided shall be conclusively presumed to have
     been duly given whether or not the holder receives the notice. On or after
     the redemption date, each holder of shares of Convertible Preferred Stock
     to be redeemed shall present and surrender such holder's certificate or
     certificates for such shares to the Corporation at the place designated in
     the redemption notice and thereupon the Corporation Redemption Price shall
     be paid to or on the order of the person whose name appears on such
     certificate or certificates as the owner thereof, and each surrendered
     certificate shall be canceled.

          (c) If a notice of redemption has been given pursuant to this Section
     5 and if, on or before the redemption date, the funds necessary for such
     redemption (including all dividends on the shares of Convertible Preferred
     Stock to be redeemed that will accrue to the redemption date) shall have
     been set aside by the Corporation, separate and apart from its other funds
     in trust for the pro rata benefit of the holders of the shares of
     Convertible Preferred Stock so called for redemption, then, notwithstanding
     that any certificates for such shares of Convertible Preferred Stock have
     not been surrendered for cancellation, on the redemption date dividends
     shall cease to accrue on the shares of the Convertible Preferred Stock to
     be redeemed, and the holders of such shares shall cease to be shareholders
     with respect to those shares and shall have no voting or other rights with
     respect thereto, except the right to receive the moneys payable upon such
     redemption, without interest thereon, upon surrender (and endorsement, if
     required by the Corporation) of their certificates, and the shares of
     Convertible Preferred Stock evidenced

                                       12
<PAGE>

     thereby shall no longer be outstanding, provided, however, nothing in this
     Section 5 will limit the right of the holders of shares of Convertible
     Preferred Stock to convert such shares after the notice of redemption has
     been given and prior to the redemption date in accordance with Section 4.
     If the holder of any shares of Convertible Preferred Stock shall not,
     within one year after the redemption date, claim the amount deposited for
     the redemption thereof, such funds shall be released to the Corporation and
     held thereby until such holder shall make a claim therefor.

          (d) If a notice of redemption has been given pursuant to this Section
     5 and any holder of shares of Convertible Preferred Stock shall, prior to
     the close of business on the Business Day immediately preceding the
     redemption date, give written notice to the Corporation pursuant to Section
     4 above of the conversion of any or all of the shares to be redeemed held
     by the holder (accompanied by a certificate or certificates for such
     shares, duly endorsed or assigned to the Corporation, as required by
     Section 4 above), then such redemption shall not become effective as to
     such shares to be converted and such conversion shall become effective as
     provided in Section 4 above, whereupon any funds deposited by the
     Corporation for the redemption of such shares shall immediately upon such
     conversion be returned to the Corporation or, if then held in trust by the
     Corporation, shall automatically and without further corporate action or
     notice be discharged from the trust.

     6. REDEMPTION AT THE OPTION OF THE HOLDERS.

          (a) Each holder of Convertible Preferred Stock shall have the right to
     require the Corporation to redeem, out of funds legally available therefor,
     any or all of such holder's shares of Convertible Preferred Stock at the
     Redemption Price, plus the amount described in the first sentence of
     Section 2(d), in connection with the occurrence of a Change of Control as
     set forth herein.

          (b) The Corporation shall notify the holders of the Convertible
     Preferred Stock in writing promptly upon the occurrence of a Change of
     Control; provided, however, that any failure by the Corporation to provide
     such notice shall not affect the right of the holders of shares of
     Convertible Preferred Stock to require a redemption of such shares in
     connection with such Change of Control. Such notice shall state the terms
     and conditions of such Change of Control.

          (c) In the event the Requisite Convertible Preferred Shareholders
     expect that a Change of Control will occur, the Requisite Convertible
     Preferred Shareholders may so notify the Corporation, which notice shall
     specify the circumstances constituting the expected Change of Control.
     Within three Business Days following the receipt by the Corporation of such
     notice, the Corporation shall notify each holder of Convertible Preferred
     Stock of the receipt of such notice from the Requisite Convertible
     Preferred Shareholders. For a period of 15 days following such notice by
     the Corporation, each holder of Convertible Preferred Stock may elect to
     have any or all of such holder's shares of Convertible Preferred Stock
     redeemed under this Section 6(c) by providing an irrevocable written notice
     (a "Section 6(c) Redemption Notice") to the Corporation of such election;
     provided, however, no redemption shall be effected prior to the

                                       13
<PAGE>

     consummation of the Change of Control. The Corporation shall effect such
     redemption on the later to occur of (i) 15 days following receipt by the
     Corporation of such Section 6(c) Redemption Notice and (ii) the date of the
     consummation of such Change of Control (such date on which redemption is
     required, the "Redemption Date") and the holders of record of shares of
     Convertible Preferred Stock being redeemed in accordance with this Section
     6(c) shall promptly deliver certificates representing the shares being
     redeemed to the Corporation or its agents. If a holder has delivered a
     Section 6(c) Redemption Notice and no Change of Control shall have been
     consummated within 180 days from the date of such Section 6(c) Redemption
     Notice, then such Section 6(c) Redemption Notice shall be null and void and
     the holders shall again be entitled to deliver a new Section 6(c)
     Redemption Notice in accordance with the terms of this Section 6(c).

          (d) If the Corporation has delivered to the holders of the Convertible
     Preferred Stock a notice pursuant to Section 6(b) above that a Change of
     Control has occurred, each holder of Convertible Preferred Stock may elect
     to have any or all of such holder's shares of Convertible Preferred Stock
     redeemed under this Section 6(d) by providing an irrevocable written notice
     (a "Section 6(d) Redemption Notice") to the Corporation of such election at
     any time prior to the 90th day following the date of the Corporation's
     notice given pursuant to Section 6(b) (the "Expiration Date"). The
     Corporation shall effect the redemption of all shares pursuant to this
     Section 6(d) on the date which is 15 days after the Expiration Date.

          (e) If, on or before any redemption date specified in paragraph (c) or
     (d) above, the funds necessary for such redemption (including all dividends
     on the shares of Convertible Preferred Stock to be redeemed that will
     accrue to the redemption date) shall have been set aside by the
     Corporation, separate and apart from its other funds in trust for the pro
     rata benefit of the holders of the shares of Convertible Preferred Stock so
     called for redemption, then, notwithstanding that any certificates for such
     shares of Convertible Preferred Stock have not been surrendered for
     cancellation, on the redemption date, dividends shall cease to accrue on
     the shares of the Convertible Preferred Stock to be redeemed, and the
     holders of such shares shall cease to be shareholders with respect to those
     shares and shall have no voting or other rights with respect thereto,
     except the right to receive the monies payable upon such redemption,
     without interest thereon, upon surrender (and endorsement, if required by
     the Corporation) of their certificates, and the shares of Convertible
     Preferred Stock evidenced thereby shall no longer be outstanding. Upon
     delivery to the Corporation of an irrevocable notice from a holder of
     Convertible Preferred Stock pursuant to paragraph (c) or (d) above, the
     right of such holder to convert the shares of Convertible Preferred Stock
     to be redeemed into shares of Common Stock pursuant to Section 4 shall
     cease and terminate. If the holder of any shares of Convertible Preferred
     Stock shall not, within one year after the redemption date, claim the
     amount deposited for the redemption thereof, such funds shall be released
     to the Corporation and held thereby until such holder shall make a claim
     therefor. On and after the redemption date pursuant to either Section 6(c)
     or (d) above (unless default shall be made by the Corporation in the
     payment of the applicable Redemption Price, in which event such rights
     shall be exercisable until such default is cured), all rights in respect of
     the shares of Convertible Preferred Stock to be redeemed, except the right
     to receive the Redemption Price, shall cease and terminate, and such shares
     shall no longer be deemed

                                       14
<PAGE>

     to be outstanding, whether or not the certificates representing such shares
     have been received by the Corporation.

          (f)  If the assets of the Corporation available for redemption of the
     Convertible Preferred Stock shall be insufficient to permit the payment of
     the entire Redemption Price required to be paid pursuant to this Section 6,
     then the holders of Convertible Preferred Stock shall share ratably in any
     such redemption based on the respective number of shares of Convertible
     Preferred Stock that each holder thereof holds.

          (g) Any communication or notice relating to redemption given pursuant
     to this Section 6 shall be sent by first-class certified mail, postage
     prepaid, to the holders of record of shares of Convertible Preferred Stock,
     at their respective addresses as the same shall appear on the books of the
     Corporation, or to the Corporation at the address of its principal, or
     registered office, as the case may be.

          (h) The Corporation shall not engage in any Sale of the Corporation
     transaction unless (i) if the Corporation shall be the surviving or
     continuing entity of such transaction, the Corporation shall, after
     consummation thereof, have sufficient funds to perform its obligations
     under this Section 6, and (ii) if the Corporation shall not be the
     surviving or continuing entity of such transaction, proper and adequate
     provision shall be made, in the definitive documentation providing for such
     transaction or otherwise, to ensure that the surviving or continuing
     corporation of such transaction shall expressly assume the Corporation's
     obligations under this Section 6 and shall have sufficient funds to perform
     its obligations under this Section 6.

          7. MANDATORY REDEMPTION.

     On the Maturity Date, the Corporation shall redeem each outstanding share
of Convertible Preferred Stock for the Liquidation Amount of such share at such
time.  If the assets of the Corporation available for redemption of the
Convertible Preferred Stock shall be insufficient to permit the payment of the
entire Liquidation Amount to which they shall be entitled, the holders of
Convertible Preferred Stock shall share ratably in any such redemption based on
the respective number of shares of Convertible Preferred Stock that each holder
thereof holds.

          8. VOTING RIGHTS.

          (a) Except as otherwise expressly provided herein or required by law
     and so long as any shares of the Convertible Preferred Stock are
     outstanding, each share of Convertible Preferred Stock shall entitle the
     holder thereof to notice of and to vote, in person or by proxy, at any
     special or annual meeting of shareholders, on all matters entitled to be
     voted on by holders of Common Stock (and any other series or class of
     Voting Stock also entitled to vote with the holders of Common Stock),
     voting together as a single class with all other shares entitled to vote
     thereon. With respect to any such vote, each share of Convertible Preferred
     Stock shall entitle the holder thereof to cast that number of votes as is
     equal to the number of votes that such holder would be entitled to cast had
     such holder converted such share of Convertible Preferred Stock into shares
     of


                                       15
<PAGE>

     Common Stock as of the record date for determining the shareholders of
     the Corporation entitled to vote on any such matters.


          (b) At any time after the Original Issuance Date, the Corporation
     shall not, and shall not permit any Subsidiary to, without first obtaining
     the affirmative written consent or approval of the Requisite Convertible
     Preferred Shareholders:

                (i) in any manner authorize, create, designate, issue, sell or
          reclassify any class or series of capital stock of the Corporation
          (including any shares of treasury stock) or rights, options, warrants
          or other securities convertible into or exercisable or exchangeable
          for capital stock or any debt security which by its terms is
          convertible into or exchangeable for any equity security or has any
          other equity feature or any security that is a combination of debt and
          equity, which, in each case, as to the payment of dividends,
          distribution of assets or Redemptions, including, without limitation,
          distributions to be made upon a Liquidation, is pari passu with, is
          senior to the Convertible Preferred Stock or is mandatorily redeemable
          prior to the Convertible Preferred Stock or which in any manner
          materially adversely affects the rights, preferences or remedies of
          the holders of the Convertible Preferred Stock;

                (ii) in any manner alter or change the terms, designations,
          powers, preferences or relative, participating, optional or other
          special rights, or the qualifications, limitations or restrictions
          thereof, of the Convertible Preferred Stock;

                (iii) in any manner authorize, create, issue or sell any
          additional shares of Convertible Preferred Stock;

                (iv) amend, alter or repeal any of the provisions of (A) the
          Articles of Incorporation of the Corporation (as amended or restated)
          or (B) the By-laws of the Corporation, if such amendment, alteration
          or repeal would alter or change the rights, preferences or privileges
          of the holders of such Convertible Preferred Stock so as to adversely
          affect them.

                (v) declare or pay any dividend with respect to, or make any
          payment on account of, or set apart assets for a sinking or other
          analogous fund for, the purchase, redemption, retirement or other
          acquisition of, any shares of any class of capital stock of the
          Corporation ranking junior to the Convertible Preferred Stock, or any
          warrants or options to purchase any such capital stock, or make any
          other distribution in respect thereof, either directly or indirectly,
          whether in cash or property or in obligations of the Corporation or
          any Subsidiary (other than a declaration or payment of a stock
          dividend payable in shares of Common Stock to the holders of Common
          Stock); provided, however, that the Corporation may declare or pay any
          dividend on (or repurchase) the Common Stock if such amount, when
          combined with the sum of all other dividends declared or paid on (plus
          all amounts paid in the repurchase of), the Common Stock in the
          preceding twelve-month period, does not exceed 5% of the aggregate
          Fair Market Value of

                                       16
<PAGE>

          the Common Stock at the time of the declaration or payment of such
          dividend or commitment to repurchase, as the case may be;

                (vi) agree to, or permit any Subsidiary to agree to, any
          provision in any agreement that would by its terms impose any
          restriction on the ability of the Corporation to honor the exercise of
          any rights of the holders of the Convertible Preferred Stock;

                (vii) enter into any transaction, including, without limitation,
          any purchase, sale, lease or exchange of property, the rendering of
          any service or the payment of any management, advisory or similar
          fees, with any Affiliate (other than any transaction between the
          Corporation and any wholly-owned Subsidiary or between or among
          wholly-owned Subsidiaries) unless such transaction is (a) in the
          ordinary course of business of the Corporation and its Subsidiaries,
          and (b) upon fair and reasonable terms no less favorable to the
          Corporation and its Subsidiaries than they would obtain in a
          comparable arm's length transaction with a Person which is not an
          Affiliate

          9.  BOARD OF DIRECTORS.

          (a) The holders of the Convertible Preferred Stock, voting as a
     separate class, shall be entitled to elect directors (the "Convertible
     Preferred Directors") to the Board as follows:

                (i) for so long as Apollo and its Affiliates hold in the
          aggregate Common Stock Equivalents representing at least 50% of the
          number of Conversion Shares issuable upon conversion of the
          Convertible Preferred Stock issued on the Original Issuance Date,
          Apollo shall be entitled to elect the greater of 3 directors or the
          number of directors that represents 30% of the Board, rounded up to
          the nearest whole director;

                (ii) for so long as Apollo and its Affiliates hold in the
          aggregate Common Stock Equivalents representing at least 25% of the
          number of Conversion Shares issuable upon conversion of the
          Convertible Preferred Stock issued on the Original Issuance Date,
          Apollo shall be entitled to elect the number of directors that
          represents 22% of the Board, rounded up to the nearest whole director;

                (iii) for so long as Apollo and its Affiliates hold in the
          aggregate Common Stock Equivalents representing at least 12 1/2% of
          the number of Conversion Shares issuable upon the conversion of the
          Convertible Preferred Stock issued on the Original Issuance Date,
          Apollo shall be entitled to elect the number of directors that
          represents 15% of the Board, rounded up to the nearest whole director.

          (b) In the event the number of directors the holders of Convertible
     Preferred Stock are entitled to elect decreases in accordance with
     paragraph (a) above, then the

                                       17
<PAGE>

     number of directors the holders of Convertible Preferred Stock are entitled
     to elect pursuant to paragraph (a) shall not thereafter be increased,
     irrespective of any subsequent acquisition of Common Stock Equivalents by
     Apollo and its Affiliates. In determining the number of directors the
     holders of the Convertible Preferred Stock shall be entitled to elect
     pursuant to paragraph (a) above, Apollo and its Affiliates shall be deemed
     to hold each Common Stock Equivalent that is held of record by Apollo or
     any of its Affiliates, or as to which Apollo or any of its Affiliates
     retains the entire economic interest.

          (c) Each committee of the Board shall include directors elected by the
     holders of shares of the Convertible Preferred Stock in the same
     proportion, rounded up to the nearest whole director, as such directors
     comprise the Board and the Corporation shall provide each Convertible
     Preferred Director with notice at least 48 hours prior to any meeting of
     the Board or any committee.

          (d) If an Event of Non-Compliance occurs (each, a "Trigger Event"),
     the Requisite Convertible Preferred Shareholders (voting as a separate
     class) shall have the special right to elect that number of individuals to
     the Board that will constitute a majority of the Board. Upon receipt by the
     Corporation of written notice of the occurrence of a Trigger Event signed
     by the Requisite Convertible Preferred Shareholders, the number of
     directors constituting the entire Board shall be increased by a number
     which, together with the number of directors which the holders of the
     Convertible Preferred Stock have elected pursuant to Section 9(a), shall
     constitute a majority of the number of directors constituting the entire
     Board. In case any vacancy shall occur among the directors elected by the
     holders of the Convertible Preferred Stock pursuant to Section 9(a) or
     9(d), a successor shall be elected by the Convertible Preferred Directors
     (or by the holders of the Convertible Preferred Stock, in the event no such
     director remains in office). Upon receipt by the Corporation of written
     consents signed by or on behalf of the Requisite Convertible Preferred
     Shareholder designating the persons to fill the vacancy, created by
     increase or otherwise, the Board shall immediately fill such vacancies with
     the designees named in such notice. In lieu of delivery of notice to the
     Corporation described in the preceding sentence, at their discretion, the
     holders of the Convertible Preferred Stock, voting separately as a single
     class, may elect such directors at any annual meeting of the shareholders
     or any special meeting of the holders of the Convertible Preferred Stock
     called as hereinafter provided. At any time during which the power to elect
     any directors has been vested in the holders of Convertible Preferred
     Stock, the Secretary of the Corporation, upon written request of any holder
     of Convertible Preferred Stock, shall call a meeting of the holders of the
     Convertible Preferred Stock for the election of directors as provided
     herein. The rights of the holders of the Convertible Preferred Stock to
     increase the number of directors and designate such additional directors,
     as provided in this Section 9(d) shall continue until such time as there is
     no longer a Trigger Event in existence, at which time such special right
     shall terminate, subject to revesting upon the occurrence and continuation
     of any subsequent Trigger Event which gives rise hereunder. After the
     expiration of such Trigger Event, the term of office of the directors
     elected pursuant to the increase under this Section 9(d) shall
     automatically expire and the number of directors shall be reduced
     accordingly.

     confer on Apollo (or such other Person as the Corporation shall approve),
     for so long as such shares remain outstanding, sole power and authority to
     vote such shares of Convertible Preferred Stock (at any meeting of
     shareholders or by execution of a written consent of shareholders), with
     respect to (i) any election of directors of the Corporation, including any
     election of directors pursuant to Section 9 of this Statement, or (ii) any
     matter described in Section 8(b)(vi). A counterpart of any such contract
     shall be deposited with the Corporation at its principal place of business
     or registered office and shall be subject to examination by shareholders,
     in accordance with Article 2.30 of the Texas Business Corporation Act. Upon
     any transfer in which the transferee does not agree to such contractual
     agreement described above, such shares of Convertible Preferred Stock shall
     automatically convert into a like number of Series B Convertible Preferred
     Stock, which shall be identical in all respects to the Convertible
     Preferred Stock, except such Series B Convertible Preferred Stock shall not
     be entitled to vote (at any meeting of shareholders or by execution of a
     written consent of shareholders) with respect to (i) any election of
     directors of the Corporation, including any election of directors pursuant
     to Section 9, or (ii) any matter described in Section 8(b)(vi).

          "Affiliate" means, with respect to any Person, any other Person that

and special purpose entities that are not operating companies, whether existing
as of the date hereof or created hereafter, if the Persons controlling Apollo
have a dominant management role in such entities.  For the purpose of the above
definition, the term "control" (including, with correlative meaning, the terms
"controlling", "controlled by", and "under common control with"), as used with
respect to any Person, means the possession, directly or indirectly, of the
power to direct or cause the direction of the management and policies of such
Person, whether through the ownership of voting securities, by contract or
otherwise.

          "Applicable Dividend Rate" means 7.25% per annum; provided however
that the Applicable Dividend Rate shall be 9.25% upon the occurrence of and
during the continuation of any Event of Non-Compliance until cured, except for

          Agreement; or

                (ii) any breach of Sections 15(a), (iii), (v), (vi), (vii), or
          (ix) through (xiii) (in the case of (xiii), only insofar as it relates
          to the foreoging clauses) of the Investor Rights Agreement that does
          not have a material adverse effect on the Corporation and its
          Subsidiaries, taken as a whole.

          "Apollo" means Apollo Management IV, L.P.

          "Appraisal Procedure" shall mean the following procedure to determine
the fair market value, as to any security, for purposes of the definition of
"Fair Market Value" or the fair market value, as to any other property (in
either case, the "valuation amount").  The valuation amount shall be determined
in good faith jointly by the disinterested members of the Board and the
Requisite Convertible Preferred Shareholders; provided, however, that if such
parties are not able to agree on the valuation amount within a reasonable period
of time (not to exceed twenty (20) days) the valuation amount shall be
determined by an investment banking firm of national recognition, which firm
shall be reasonably acceptable to the disinterested members of the Board and the
Requisite Convertible Preferred Shareholders.  If the disinterested members of
the Board and the Requisite Convertible Preferred Shareholders are unable to
agree upon an acceptable investment banking firm within ten (10) days after the
date either party proposed that one be selected, the investment banking firm
will be selected by an arbitrator located in New York City, New York, selected
by the American Arbitration Association (or if such organization ceases to
exist, the arbitrator shall be chosen by a court of competent jurisdiction).
The arbitrator shall select the investment banking firm (within ten (10) days of
his appointment) from a list, jointly prepared by the disinterested members of
the Board and the Requisite Convertible Preferred Shareholders, of not more than
six investment banking firms of national standing in the United States, of which
no more than three may be named by the disinterested members of the Board and no
more than three may be named by the Requisite Convertible Preferred
Shareholders.  The arbitrator may consider, within the ten-day period allotted,
arguments from the parties regarding which investment banking firm to choose,
but the selection by the arbitrator shall be made in its sole discretion from
the list of six.  The disinterested members of the Board and the Requisite
Convertible Preferred Shareholders shall submit to the investment banking firm
their respective determinations of the valuation amount, and any supporting
arguments and other data as they may desire, within ten (10) days of the
appointment of the investment banking firm, and the investment banking firm
shall as soon as practicable thereafter make its own determination of the
valuation amount.  The final valuation amount for purposes hereof shall be the
average of the two valuation amounts closest together, as determined by the
investment banking firm, from among the valuation amounts submitted by the
Corporation and the Requisite Convertible Preferred Shareholders and the
valuation amount calculated by the investment banking firm.  The determination
of the final valuation amount by such investment-banking firm shall be final and
binding upon the parties.  The party that submits the valuation amount that is
not used by the investment banking firm to calculate the final valuation amount
shall pay the fees and expenses of the investment banking firm and arbitrator
(if any) used to determine the valuation amount.  If required by any such
investment banking firm or arbitrator, the Corporation shall execute a retainer
and engagement letter containing reasonable terms and conditions, including,
without limitation, customary provisions concerning the rights of
indemnification and contribution by the

paid in Qualified Capital Stock) paid, accrued or scheduled to be paid or
accrued during such period times (y) a fraction, the numerator of which is one
and the denominator of which is one minus the then current effective

to the Transactions and non-cash charges related to the acceleration of the
vesting of options), (c) the net in-

                                      -7-

come of any Person acquired in a "pooling of interests" transaction accrued
prior to the date it becomes a Restricted Subsidiary of the referent Person or
is merged or consolidated with the referent Person or any Restricted Subsidiary
of the referent Person, (d) the net income (but not loss) of any Restricted
Subsidiary of the referent Person to the extent that the declaration of
dividends and the making of loans or advances or similar distributions, loans or
advances by that Restricted Subsidiary of that income is restricted by a
contract, operation of law or otherwise, (e) the net income of any Person, other

                                THE SECURITIES

SECTION 2.01.  Form and Dating.
               ---------------

          The Securities and the Trustee's certificate of authentication shall
be substantially in the form of Exhibit A hereto. The Securities may have
                                ---------
notations, legends or endorsements required by law, stock exchange rule or
usage. The Company shall approve the form of the Securities and any notation,
legend or endorsement on them. Each Security shall be dated the date of its
issuance and show the date of its authentication. Each Security shall have an
executed Guarantee from each of the Guarantors endorsed thereon substantially in
the form of Exhibit E.
            ---------

          The terms and provisions contained in the Securities and the
Guarantees shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company, the Guarantors and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

          Securities offered and sold in reliance on Rule 144 and Securities
offered and sold in reliance on Regulation S shall be issued initially in the
form of one or more Global Securities, substantially in the form set forth in
Exhibit A, deposited with the Trustee, as custodian for the Depository, duly
- ---------
executed by the Company (and having an executed Guarantee from each of the
Guarantors endorsed thereon) and authenticated by

                                     -34-
<PAGE>

the Trustee as hereinafter provided and shall bear the legends set forth in
Exhibit B. The aggregate principal amount of the Global Securities may from time
- ---------
to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided.

          Securities issued in exchange for interests in a Global Security
pursuant to Section 2.16 may be issued in the form of permanent certificated
Securities in registered form in substantially the form set forth in Exhibit A
                                                                     ---------
(the "Physical Securities").
      -------------------

SECTION 2.02.  Execution and Authentication.
               ----------------------------

          Two Officers, or an Officer and an Assistant Secretary, shall sign, or
one Officer shall sign and one Officer or an Assistant Secretary (each of whom
shall, in each case, have been duly authorized by all requisite corporate
actions) shall attest to, the Securities for the Company by manual or facsimile
signature.

          If an Officer whose signature is on a Security or Guarantee, as the
case may be, was an Officer at the time of such execution but no longer holds
that office at the time the Trustee authenticates the Security, the Security
shall nevertheless be valid.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall authenticate Securities for original issue on the
Issue Date in the aggregate principal amount of $200,000,000 upon a written
order of the Company in the form of an Officers' Certificate. In addition, the
Trustee shall authenticate Securities for original issue after the Issue Date in
the aggregate principal amount of up to $200,000,000 upon a written order of the
Company in the form of an Officers' Certificate. Each such Officers' Certificate
shall specify the amount of Securities to be authenticated and the date on which
the Securities are to be authenticated. The aggregate principal amount of
Securities outstanding at any time may not exceed $400,000,000, except as
provided in Section 2.07.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate Securities.

                                     -35-
<PAGE>

Unless otherwise provided in the appointment, an authenticating agent may
authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as an Agent to deal with the
Company and Affiliates of the Company.

          The Securities shall be issuable only in registered form without
coupons in denominations of $1,000 and integral multiples thereof.

SECTION 2.03.  Registrar and Paying Agent.
               --------------------------

          The Company shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where (a) Securities may be presented or
surrendered for registration of transfer or for exchange ("Registrar"), (b)
                                                           ---------
Securities may be presented or surrendered for payment ("Paying Agent") and (c)
                                                         ------------
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company may also from time to time designate one or
more other offices or agencies where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or reacission shall in
              --------  -------
any manner relieve the Company of its obligation to maintain an office or agency
in the Borough of Manhattan, The City of New York, for such purposes. The
Company may act as its own Registrar, Paying Agent or Calculation Agent except
that for the purposes of Articles Three and Eight and Sections 4.15 and 4.16,
neither the Company nor any Affiliate of the Company shall act as Paying Agent.
The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company, upon notice to the Trustee, may have one or more
co-Registrars and one or more additional paying agents reasonably acceptable to
the Trustee. The term "Paying Agent" includes any additional paying agent. The
Company initially appoints the Trustee as Registrar and Paying Agent until such
time as the Trustee has resigned or a successor has been appointed.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee, in advance of the name and address of any such Agent. If the
Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as
such.

                                     -36-

<PAGE>

SECTION 2.04.  Paying Agent To Hold Assets in Trust.
               ------------------------------------

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that, subject to Article Four and Article Twelve, each Paying
Agent shall hold in trust for the benefit of Holders or the Trustee all assets
held by the Paying Agent for the payment of principal of, or interest on, the
Securities (whether such assets have been distributed to it by the Company or
any other obligor on the Securities), and shall notify the Trustee of any
Default by the Company (or any other obligor on the Securities) in making any
such payment. If the Company or a Subsidiary acts as Paying Agent, it shall
segregate such assets and hold them as a separate trust fund. The Company at any
time may require a Paying Agent to distribute all assets held by it to the
Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent shall have no further liability for such assets.

SECTION 2.05.  Holder Lists.
               ------------

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Company shall furnish to the
Trustee on or before each Interest Payment Date and at such other times as the
Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Holders, which list
may be conclusively relied upon by the Trustee.

SECTION 2.06.  Transfer and Exchange.
               ---------------------

          Subject to Sections 2.15 and 2.16, when Securities are presented to
the Registrar or a co-Registrar with a request to register the transfer of such
Securities or to exchange such Securities for an equal principal amount of
Securities of other authorized denominations, the Registrar or co-Registrar
shall register the transfer or make the exchange as requested if its
requirements for such transaction are met; provided, however, that the
                                           --------  -------
Securities surrendered for transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Registrar

                                     -37-
<PAGE>

or co-Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing. To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Securities at the
Registrar's or co-Registrar's request. No service charge shall be made for any
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith. The Registrar or co-Registrar shall not be required to
register the transfer of or exchange of any Security (i) during a period
beginning at the opening of business 15 days before the mailing of a notice of
redemption of Securities and ending at the close of business on the day of such
mailing, (ii) selected for redemption in whole or in part pursuant to Article
Three, except the unredeemed portion of any Security being redeemed in part, and
(iii) during a Change of Control Offer or an Net Proceeds Offer if such Security
is tendered pursuant to such Change of Control Offer or Net Proceeds Offer and
not withdrawn.

          Any Holder of a beneficial interest in a Global Security shall, by
acceptance of such beneficial interest, agree that transfers of beneficial
interests in such Global Securities may be effected only through a book entry
system maintained by the Holder of such Global Security (or its agent), and that
ownership of a beneficial interest in the Security shall be required to be
reflected in a book entry system.

SECTION 2.07.  Replacement Securities.
               ----------------------

          If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security claims that the Security has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the Trustee's requirements are met. If required by the Trustee or
the Company, such Holder must provide an indemnity bond or other indemnity,
sufficient in the judgment of both the Company and the Trustee, to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Security is replaced. The Company may charge such Holder for its reasonable
out-of-pocket expenses in replacing a Security pursuant to this Section 2.07,
including reasonable fees and expenses of counsel.

          Every replacement Security is an additional obligation of the Company
and every replacement Guarantee shall constitute an additional obligation of the
Guarantors.

                                     -38-

<PAGE>

SECTION 2.08.  Outstanding Securities.
               ----------------------

          Securities outstanding at any time are all the Securities that have
been authenticated by the Trustee except those cancelled by it, those delivered
to it for cancellation and those described in this Section as not outstanding. A
Security does not cease to be outstanding because the Company, the Guarantors or
any of their respective Affiliates holds the Security (subject to the provisions
of Section 2.09).

          If a Security is replaced pursuant to Section 2.07 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a protected purchaser. A mutilated Security ceases to be outstanding
upon surrender of such Security and replacement thereof pursuant to Section
2.07. If the principal amount of any Security is considered paid under Section
4.01, it ceases to be outstanding and interest ceases to accrue.

          If on a Redemption Date or the Maturity Date the Paying Agent (other
than the Company or a Subsidiary) holds U.S. Legal Tender or U.S. Government
Obligations sufficient to pay all of the principal and interest due on the
Securities payable on that date, then on and after that date such Securities
cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09.  Treasury Securities.
               -------------------

          In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, any of its Subsidiaries or any of their respective Affiliates
shall be disregarded, except that, for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Securities that the Trustee knows or has reason to know are so owned shall
be disregarded.

SECTION 2.10.  Temporary Securities.
               --------------------

          Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Securities in exchange for temporary Securities. Until
such exchange, tempo-

                                     -39-

<PAGE>

rary Securities shall be entitled to the same rights, benefits and privileges as
definitive Securities. Notwithstanding the foregoing, so long as the Securities
are represented by a Global Security, such Global Security may be in typewritten
form.

SECTION 2.11.  Cancellation.
               ------------

          The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Company or a Subsidiary), and no one else, shall cancel and, at
the written direction of the Company, shall dispose of all Securities
surrendered for transfer, exchange, payment or cancellation. Subject to Section
2.07, the Company may not issue new Securities to replace Securities that it has
paid or delivered to the Trustee for cancellation. If the Company or any
Guarantor shall acquire any of the Securities, such acquisition shall not
operate as a redemption or satisfaction of the Indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for
cancellation pursuant to this Section 2.11.

SECTION 2.12.  Defaulted Interest.
               ------------------

          If the Company defaults in a payment of interest on the Securities, it
shall, unless the Trustee fixes another record date pursuant to Section 6.10,
pay the defaulted interest, plus (to the extent lawful) any interest payable on
the defaulted interest, in any lawful manner. The Company may pay the defaulted
interest to the persons who are Holders on a subsequent special record date,
which date shall be the fifteenth day next preceding the date fixed by the
Company for the payment of defaulted interest or the next succeeding Business
Day if such date is not a Business Day. At least 15 days before any such
subsequent special record date, the Company shall mail to each Holder, with a
copy to the Trustee, a notice that states the subsequent special record date,
the payment date and the amount of defaulted interest, and interest payable on
such defaulted interest, if any, to be paid.

SECTION 2.13.  CUSIP Number.
               ------------

          The Company in issuing the Securities may use a "CUSIP" number, and if
so, the Trustee shall use the CUSIP number in notices of redemption or exchange
as a convenience to

                                     -40-
<PAGE>

Holders; provided, however, that any such notice may state that no
         --------  -------
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Securities, and that reliance may be placed only
on the other identification numbers printed on the Securities.

SECTION 2.14.  Deposit of Moneys.
               -----------------

          Prior to 11:00 a.m. New York City time on each Interest Payment Date,
Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds
Offer Payment Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control
Payment Date and Net Proceeds Offer Payment Date, as the case may be, in a
timely manner which permits the Paying Agent to remit payment to the Holders on
such Interest Payment Date, Maturity Date, Redemption Date, Change of Control
Payment Date and Net Proceeds Offer Payment Date, as the case may be.

SECTION 2.15.  Book-Entry Provisions for Global Securities.
               -------------------------------------------

          (a)  The Global Securities initially shall (i) be registered in the
name of the Depository or the nominee of such Depository, (ii) be delivered to
the Trustee as custodian for such Depository and (iii) bear legends as set forth
in Exhibit B.
   ---------

          Members of, or participants in, the Depository ("Participants") shall
                                                           ------------
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Global Security, and the Depository may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner of the Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and Participants, the operation of customary practices governing the exercise of
the rights of a Holder of any Security.

          (b)  Transfers of Global Securities shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Securities may be
transferred or ex-

                                     -41-
<PAGE>

changed for Physical Securities in accordance with the rules and procedures of
the Depository and the provisions of Section 2.16. In addition, Physical
Securities shall be transferred to all beneficial owners in exchange for their
beneficial interests in Global Securities if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for any Global
Security and a successor Depository is not appointed by the Company within 90
days of such notice or (ii) an Event of Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue
Physical Securities.

          (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in a Global Security to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Securities are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of such Global Security in an amount equal to the principal
amount of the beneficial interest in the Global Security to be transferred, and
the Company shall execute, and the Trustee shall authenticate and deliver, one
or more Physical Securities of authorized denominations in an aggregate
principal amount equal to the principal amount of the beneficial interest in the
Global Security so transferred.

          (d)  In connection with the transfer of a Global Security as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15,
such Global Security shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, the Guarantors shall execute
Guarantees on and the Trustee shall upon written instructions from the Company
authenticate and deliver, to each beneficial owner identified by the Depository
in exchange for its beneficial interest in such Global Security, an equal
aggregate principal amount of Physical Securities of authorized denominations.

          (e)  Any Physical Security constituting a Restricted Security
delivered in exchange for an interest in a Global Security pursuant to paragraph

                                  REDEMPTION


SECTION 3.01.  Notices to Trustees.
               -------------------

          If the Company elects to redeem Securities pursuant to Paragraph 6 or
Paragraph 7 of the Securities, it shall notify the Trustee in writing of the
Redemption Date, the Redemption Price and the principal amount of Securities
to be redeemed. The Company shall give notice of redemption to the Paying Agent
and Trustee at least 45 days but not more than 60 days before the Redemption
Date (unless a shorter notice shall be agreed to by the Trustee in writing),
together with an Officers' Certificate stating that such redemption will comply
with the conditions contained herein.

SECTION 3.02   Selection of Securities To Be Redeemed
               --------------------------------------

          In the event that less than all of the Securities are to be
redeemed at any time, selection of such Securities for redemption will be made
by the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which such Securities are listed or, if such
Securities are not then listed on a national securities exchange, on a pro rata
                                                                       --- ----
basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided, however, that no Securities of a principal amount of $1,000 or less
- --------  -------
shall be redeemed in part; and provided, further, that if a partial redemption
                               --------  -------
is made with the net cash proceeds of an Equity Offering, selection of the
Securities or portions thereof for redemption shall be made by the Trustees only
on a pro rata basis or on as nearly a pro rata basis as is practicable (subject
     --- ----                         --- ----
to the procedures of the Depository) unless such method is otherwise prohibited.

                                     -46-
<PAGE>

SECTION 3.03.  Notice of Redemption.
               --------------------

          At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail a notice of redemption by first class mail, postage
prepaid, to each Holder whose Securities are to be redeemed at its registered
address. At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. Each notice for
redemption shall identify the Securities to be redeemed and shall state:

          (1)  the Redemption Date;

          (2)  the Redemption Price and the amount of accrued interest, if any,
     to be paid;

          (3)  the name and address of the Paying Agent;

          (4)  that Securities called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price plus accrued interest, if any;

          (5)  that, unless the Company defaults in making the redemption
     payment, interest on Securities called for redemption ceases to accrue on
     and after the Redemption Date, and the only remaining right of the Holders
     of such Securities is to receive payment of the Redemption Price upon
     surrender to the Paying Agent of the Securities redeemed;

          (6)  if any Security is being redeemed in part, the portion of the
     principal amount of such Security to be redeemed and that, after the
     Redemption Date, and upon surrender of such Security, a new Security or
     Securities in aggregate principal amount equal to the unredeemed portion
     thereof will be issued;

          (7)  if fewer than all the Securities are to be redeemed, the
     identification of the particular Securities (or portion thereof) to be
     redeemed, as well as the aggregate principal amount of Securities to be
     redeemed and the aggregate principal amount of Securities to be outstanding
     after such partial redemption; and

          (8)  the Paragraph of the Securities pursuant to which the Securities
     are to be redeemed.

                                     -47-



<PAGE>

          The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption in whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

SECTION 3.04.  Effect of Notice of Redemption.
               ------------------------------

          Once notice of redemption is mailed in accordance with Section 3.03,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price plus accrued interest, if any. Upon surrender to the
Trustee or Paying Agent, such Securities called for redemption shall be paid at
the Redemption Price (which shall include accrued interest thereon to the
Redemption Date), but installments of interest, the maturity of which is on or
prior to the Redemption Date, shall be payable to Holders of record at the close
of business on the relevant Record Dates.

SECTION 3.05.  Deposit of Redemption Price.
               ---------------------------
          On or before 11.00 a.m. New York time on the Redemption Date, the
Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay
the Redemption Price plus accrued interest, if any, of all Securities to be
redeemed on that date.

          If the Company complies with the preceding paragraph, then, unless the
Company defaults in the payment of such Redemption Price plus accrued interest,
if any, interest on the Securities to be redeemed will cease to accrue on and
after the applicable Redemption Date, whether or not such Securities are
presented for payment.

SECTION 3.06.  Securities Redeemed in Part.
               ---------------------------

          Upon surrender of a Security that is to be redeemed in part only, the
Trustee shall upon written instruction from the Company authenticate for the
Holder a new Security or Securities in a principal amount equal to the
unredeemed portion of the Security surrendered.

SECTION 4.01.  Payment of Securities.

          The Company shall pay the principal of and interest on the Securities
in the manner provided in the Securities. An installment of principal of or
interest on the Securities shall be considered paid on the date it is due if the
Trustee or Paying Agent holds on that date U.S. Legal Tender designated for and
sufficient to pay the installment. Interest on the Securities will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 4.02.  Maintenance of Office or Agency.
               -------------------------------

          The Company shall maintain in the Borough of Manhattan, The City of
New York, the office or agency required under Section 2.03. The Company shall
give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth in Section 13.02.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

          The Company hereby initially designates the Corporate Trust Office of
the Trustee located in the Borough of Manhattan, The City of New York, as such

     Company and its Restricted Subsidiaries separate from the financial

     Company, if any) and, with respect to the annual information only, a report

                                     -55-

<PAGE>

     thereon by the Company's certified independent accountants; and

     Commission's rules and regulations.

          In addition, following the consummation of the exchange offer
contemplated by the Registration Rights Agreement, whether or not required by
the rules and regulations of the Commission, the Company will file a copy of all
such information and reports with the Commission for public availability within
the time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. In addition, for so
long as any Securities remain outstanding, the Company shall furnish to the
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A (d) (4)

it may lawfully do so) that it will not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the
Company or such Guarantor from paying all or any portion of the principal of
and/or interest on the Securities or the Guarantee of any such Guarantor as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture, and (to the
extent that it may lawfully do so) each hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

SECTION 4.12.  Limitations on Transactions with Affiliates.
               -------------------------------------------

          (a)  The Company shall not, and shall not permit any of its Restricted

                                     -56-
<PAGE>

ter into or permit to exist any transaction or series of related transactions
(including, without limitation, the purchase, sale, lease or exchange of any
property or the rendering of any service) with, or for the benefit of, any of
its Affiliates (each an "Affiliate Transaction"), other than (x) Affiliate
                         ---------------------
Transactions permitted under paragraph (b) below and (y) Affiliate Transactions
on terms that are no less favorable than those that might reasonably have been
obtained in a comparable transaction at such time on an arm's-length basis

Subsidiary. All Affiliate Transactions (and each series of related Affiliate
Transactions which are similar or part of a common plan) involving aggregate

shall be approved by the Board of Directors of the Company or such Restricted
Subsidiary, as the case may be, such approval to be evidenced by a Board
Resolution stating that such Board of Directors has determined that such
transaction complies with the foregoing provisions. If the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction (or a
series of related Affiliate Transactions related to a common plan) that involves
an aggregate fair market value of more than $10.0 million, the Company or such
Restricted Subsidiary, as the case may be, shall, prior to the consummation
thereof, obtain a favorable opinion as to the fairness of such transaction or
series of related transactions to the Company or the relevant Restricted
Subsidiary, as the case may be, from a financial point of view, from an
Independent Financial Advisor and file the same with the Trustee.

          (b)  The restrictions set forth in clause (a) shall not apply to (i)
reasonable fees and compensation paid to and indemnity provided on behalf of,
officers, directors, employees, consultants or investment bankers of the Company
or any Restricted Subsidiary of the Company as determined in good faith by the
Company's Board of Directors or senior management; (ii) transactions exclusively
between or among the Company and any of its Wholly Owned Restricted
Subsidiaries, or exclusively between or among such Wholly Owned Restricted
Subsidiaries, provided such transactions are not otherwise prohibited by this
              --------
Indenture; (iii) any agreement as in effect as of the Issue Date or any
amendment thereto or any transaction contemplated thereby (including pursuant to
any amendment thereto) or any replacement agreement thereto so long as any such
amendment or replacement agreement is not more disadvantageous to the Holders in
any material respect than the original agreement as in effect on the Issue Date;
(iv) Restricted Payments permitted by this Indenture; (v) transactions in which
the Company or any of

                                     -57-
<PAGE>

its Restricted Subsidiaries, as the case may be, delivers to the Trustee a
letter from an Independent Financial Advisor stating that such transaction is
fair to the Company or such Restricted Subsidiary from a financial point of view
or meets the requirements of the first sentence of this Section 4.12; (vi) the
existence of, or the performance by the Company or any of its Restricted
Subsidiaries of its obligations under the terms of, the Investors' Rights
Agreement, the Securities Purchase Agreement, any stockholders' agreement
(including any registration rights agreement or purchase agreement related
thereto) to which it is a party as of the Issue Date and any similar agreements
which it may enter into thereafter; provided, however, that the existence of, or
                                    --------  -------
the performance by the Company or any of its Restricted Subsidiaries of
obligations under, any future amendment to any such existing agreement or under
any similar agreement entered into after the Issue Date shall only be permitted
by this clause (vi) to the extent that the terms of any such amendment or new
agreement are not otherwise disadvantageous to the Holders of the Securities in
any material respect; (vii) the issuance of securities or other payments, awards
or grants, in cash, securities or otherwise, pursuant to, or the funding of,
employment arrangements, stock options and stock ownership plans approved by the
Board of Directors of the Company in good faith and loans to employees of the
Company and its Subsidiaries which are approved by senior management of the
Company in good faith; (viii) the payment of all fees and expenses related to
the Transactions; (ix) transactions with customers, clients, suppliers,
purchasers or sellers of goods or services, in each case in the ordinary course
of business and otherwise in compliance with the terms of this Indenture, which
are fair to the Company or its Restricted Subsidiaries, in the reasonable
determination of senior management of the Company, or are on terms at least as
favorable as might reasonably have been obtained at such time from an
unaffiliated party; and (x) transactions reasonably related to (x) the exercise
of rights and remedies with respect to the Convertible Subordinated Notes or (y)
the conversion or exchange of the Convertible Subordinated Notes (each to the
extent not otherwise prohibited in this Indenture).

               Restricted Subsidiaries.
               ---------------------------------------------------------------

          The Company shall not, and shall not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or

     reason of: (1) applicable law; (2) this Indenture; (3) customary non-
     assignment provisions of any contract or any lease governing a leasehold
     interest of, or any license held by, any Restricted Subsidiary of the
     Company; (4) any instrument governing Acquired Indebtedness, which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person or the
     properties or assets of the Person so acquired; (5) the Credit Agreement;
     (6) agreements existing on the Issue Date to the extent and in the manner
     such agreements are in effect on the Issue Date; (7) an agreement governing
     Indebtedness incurred to Refinance the Indebtedness issued, assumed or
     incurred pursuant to an agreement referred to in clauses (2), (4), (5) or

     Indebtedness are no less favorable to the Company in any material respect
     as determined by the Board of Directors of the Company or senior management
     in its reasonable and good faith judgment than the provisions relating to
     such encumbrance or restriction contained in agreements referred to in such
     clause (2), (4), (5), (6), (8), and (10); (8) purchase money obligations
     for property acquired in the ordinary course of business that impose
     restrictions of the nature discussed in clause (c) above on the property so
     acquired; (9) contracts for the sale of assets, including without
     limitation, customary restrictions with respect to a Restricted Subsidiary
     of the Company pursuant to an agreement that has been entered into for the
     sale or disposition of the Capital Stock or assets of such Restricted
     Subsidiary; (10) secured Indebtedness otherwise permitted to be incurred
     pursuant to Sections 4.04 and 4.14 that limits the right of the debtor to
     dispose of the assets securing such Indebtedness; (11) customary provisions
     in joint venture agreements, licenses and leases and other similar
     agreements entered into in the ordinary course of business; (12) net worth
     provisions in leases and other agreements entered into by the Company or
     any Restricted Subsidiary; and (13) an agreement governing Indebtedness
     (including any Credit Facilities) permitted to be incurred pursuant to

<PAGE>

material respect as determined by senior management of the Company in its

                                  --------  -------

Refinanced and (y) do not extend to or cover any property or assets of the
Company or any of its Restricted Subsidiaries not securing the Indebtedness so

SECTION 4.15.  Change of Control.
               -----------------

          (a)  Upon the occurrence of a Change of Control, the Company shall be

     Change of Control Offer will be required to surrender the Security, with
     the form entitled "Option of Holder to Elect Purchase" on the reverse of
     the Security completed, to the Paying Agent at the address specified in the
     notice prior to the close of business on the third Business Day prior to
     the Change of Control Payment Date;

          (6)  that Holders will be entitled to withdraw their election if the

     Securities the Holder delivered for purchase and a statement that such
     Holder is withdrawing his election to have such Security purchased;

          (7)  that Holders whose Securities are purchased only in part will be
     issued new Securities in a principal amount equal to the unpurchased
     portion of the Securities surrendered; and

Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price plus accrued interest, if any, of all
Securities so tendered and (iii) deliver to the Trustee Securities so accepted

management or, in the case of an Asset Sale in excess of $5 million, by the
Company's Board of Directors); (ii) at least 75% of the consideration received
by the Company or the Restricted Subsidiary, as the case may be, from such Asset

by the Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash within 180 days

credit facility, effect a permanent reduction in the availability under such
revolving credit facility, (B) to make an Investment in properties and assets
that replace the properties and assets

                                     -63-

and/or (C) a combination of prepayment and investment permitted by the foregoing
clauses (iii) (A) and (iii) (B). On the 361st day after an Asset Sale or such

                      --------  -------
consideration received by the Company or any Restricted Subsidiary of the
Company, as the case may be, in connection with any Asset Sale is converted into
or sold or otherwise disposed of for cash (other than interest received with
respect to any such non-cash consideration), then such conversion or disposition
shall be deemed to constitute an Asset Sale hereunder and the Net cash Proceeds
thereof shall be applied in accordance with this Section 4.16. The Company may
defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds
Offer Amount equal to or in excess of $10.0 million resulting from one or more
Asset Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and
not just the amount in excess of $10.0 million, shall be applied as required
pursuant to this paragraph).

     In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 5.01, which
transaction does not constitute a Change of Control, the successor corporation
shall be deemed to have sold the properties and assets of the Company and its
Restricted Subsidiaries not so transferred for purposes

with respect to such deemed sale as if it were an Asset Sale. In addition, the
fair market value of such properties and assets of the Company or its Restricted
Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for
purposes of this Section 4.16.

          Notwithstanding the first two paragraphs of this Section 4.16, the
Company and its Restricted Subsidiaries will be permitted to consummate an Asset
Sale without complying with such paragraphs to the extent:

          (1)  at least 75% of the consideration for such Asset Sale constitutes
     Replacement Assets; and

          (2)  such Asset Sale is for fair market value;

provided that any consideration not constituting Replacement Assets received by
- --------
the Company or any of its Restricted Subsidiaries in connection with any Asset
Sale permitted to be consummated under this paragraph shall constitute Net Cash
Proceeds subject to the provisions of the first two paragraphs of this Section
4.16.

          Notice of each Net Proceeds Offer pursuant to this Section 4.16 shall
be mailed or caused to be mailed, by first class mail, by the Company within 30
days following the applicable Net Proceeds Offer Trigger Date to all Holders at
their last registered addresses, with a copy to the Trustee. A Net Proceeds
Offer shall remain open for a period of 20 Business Days or such longer period
as may be required by law. The notice shall contain all instructions and
materials necessary to enable such Holders to tender Securities pursuant to the
Net Proceeds Offer and shall state the following terms:

          (1)  that the Net Proceeds Offer is being made pursuant to this
     Section 4.16 and that all Securities tendered will be accepted for payment;
     provided, however, that if the principal amount of Securities tendered in
     --------  -------
     the Net Proceeds Offer exceeds the aggregate amount of Net Proceeds Offer
     Amount, the Company shall select the Securities to be purchased on a pro
     rata basis;

          (2)  the purchase price (including the amount of accrued interest, if
     any) and the purchase date (which shall be no earlier than 30 days nor
     later than 60 days from the date such notice is mailed, other than as may
     be required by applicable law);

                                     -65-
<PAGE>

     (3)  that any Security not tendered will continue to accrue interest;

     (4)  that, unless the Company defaults in making payment therefor, any
  Security accepted for payment pursuant to the Net Proceeds Offer shall cease
  to accrue interest after the Net Proceeds Offer Payment Date;

     (5)  that Holders electing to have a Security purchased pursuant to the Net
  Proceeds Offer will be required to surrender the Security, with the form
  entitled "Option of Holder to Elect Purchase" on the reverse of the Security
  completed, to the Paying Agent at the address specified in the notice prior to
  the close of business on the Net Proceeds Offer Payment Date;

     (6)  that Holders will be entitled to withdraw their election if the Paying

  delivered for purchase and a statement that such Holder is withdrawing his
  election to have such Security purchased; and

     (7)  that Holders whose Securities are purchased only in part will be
  issued new Securities in a principal amount at maturity equal to the
  unpurchased portion of the Securities surrendered.

     On or before the Net Proceeds Offer Payment Date, the Company shall
(i) accept for payment Securities or portions thereof tendered pursuant to the
Net Proceeds Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price, plus accrued interest, if any, of all
Securities to be purchased and (iii) deliver to the Trustee Securities so
accepted together with an Officers' Certificate stating the Securities or
portions thereof being purchased by the Company. The Paying Agent shall promptly
mail to the Holders of Securities so accepted payment in an amount equal to the
purchase price, plus accrued interest, if any, thereon set forth in the notice
of such Net Proceeds Offer. Any Security not so accepted shall be promptly
mailed by the Company to the Holder thereof. For purposes of this Section 4.16,
the Trustee shall act as the Paying Agent. Any amounts remaining after the
purchase of Securities pursuant to a Net Proceeds Offer shall be returned by the
Trustee to the Company.

          The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Securities pursuant to a Net Proceeds Offer. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.16, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 4.16 by virtue thereof.

              ----------------------------

          The Company shall not, and shall not permit any Restricted Subsidiary
that is a Guarantor to, incur or suffer to exist Indebtedness that is senior in
right of payment to the Securities or such Guarantor's Guarantee, as the case
may be, and subordinate in right of payment to any other Indebtedness of the
Company or such Guarantor, as the case may be.

SECTION 4.18. Additional Subsidiary Guarantees.

transactions, any property to any Domestic Restricted Subsidiary that is not a
Guarantor, or if the Company or any of its Restricted Subsidiaries shall
organize, acquire or otherwise invest in another Domestic Restricted Subsidiary
having total assets with a book value in excess of $1 million, then such
transferee or acquired or other Restricted Subsidiary shall (i) execute and
deliver to the Trustee a supplemental indenture pursuant to which such
Restricted Subsidiary shall unconditionally guarantee all of the Company's
obligations under the Securities and this Indenture on the terms set forth in
this Indenture and (ii) deliver to the Trustee an Opinion of Counsel that such
supplemental indenture has been duly authorized, executed and delivered by such
Restricted Subsidiary and constitutes a legal, valid, binding and enforceable
obligation of such Restricted Subsidiary. Thereafter, such Restricted Subsidiary
shall be a Guarantor for all purposes of this Indenture.

SECTION 4.19. Conduct of Business.
              -------------------

          The Company and its Restricted Subsidiaries shall not engage in any

          (b)  For purposes of the foregoing paragraph (a), the transfer (by

     Twelve of this Indenture);

          (b)  the failure to pay the principal on any Securities, when such
     principal becomes due and payable, at maturity, upon redemption or

     the Holders of at least 25% of the outstanding principal amount of the
     Securities;

          (d)  the failure to pay at final maturity (giving effect to any

     is not rescinded, annulled or otherwise cured within 20 days of receipt by
     the Company or such Significant Subsidiary of notice of any such
     acceleration) if the aggregate principal amount of such Indebtedness,
     together with the principal amount of any other such Indebtedness in

     accelerated (in each case with respect to which the 20-day period described
     above has passed), aggregates $10.0 million or more at any time;

          (e)  one or more judgments in an aggregate amount in excess of $10.0

     Subsidiary denies its liability under its Gaurantee (other than by reason
     of release of a Guarantor in accordance with the terms of this Indenture).

SECTION 6.02.  Acceleration.
               ------------

          If an Event of Default (other than an Event of Default specified in
either clause (f) or (g) of Section 6.01 above with respect to the Company)
shall occur and be continuing, the Trustee or the Holders of at least 25% in
principal amount of outstanding Securities may declare the principal of and
accrued interest on all the Securities to be due and payable by notice in
writing to the Company (and the Trustee if given by the Holders) specifying the
respective Event of Default and that it is a "notice of acceleration" (the
"Acceleration Notice"), and the same (i) shall become immediately due and
 -------------------
payable or (ii) if there are any amounts outstanding under the Credit Agreement,
shall become immediately due and payable upon the first to occur of an
acceleration under the Credit Agreement or 5 business days after receipt by the
Company and the Representative under the Credit Agreement of such Acceleration
Notice but only if such Event of Default is then continuing. If an Event of
Default specified in either clause (f) or (g) of Section 6.01 above with respect
to the Company occurs and is continuing, then all unpaid principal of, and
premium, if any, and accrued and unpaid interest on all of the outstanding
Securities shall ipso facto become and be immediately due and payable without
                 ---- -----
any declaration or other act on the part of the trustee or any Holder.

                                     -72-

<PAGE>

          At any time after a declaration of acceleration with respect to the
Securities as described in the preceding paragraph, the Holders of a majority
in principal amount of the Securities may rescind and cancel such declaration
and its consequences (i) if the rescission would not conflict with any judgment
or decree, (ii) if all existing Events of Default have been cured or waived
except nonpayment of principal or interest that has become due solely because
of the acceleration, (iii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid,
(iv) if the Company has paid the Trustee its reasonable compensation and
reimbursed the Trustee for its expenses, disbursements and advances and (v) in
the event of the cure or waiver of an Event of Default of the type described in
either clause (f) or (g) of Section 6.01, the Trustee shall have received an
Officers' Certificate and an Opinion of Counsel that such Event of Default has
been cured or waived. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

SECTION 6.03.  Other Remedies.
               --------------

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

SECTION 6.04.  Waiver of Past Defaults.
               -----------------------

          Subject to Sections 2.09, 6.07 and 9.02, the Holders of not less than
a majority in principal amount of the outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences,
except a Default in the payment of principal of or interest on any Security as
specified in clauses (a) and (b) of Section 6.01. The Company shall deliver to
the Trustee an Officers' Certificate stating that the requisite percentage of
Holders have con-

                                     -73-

<PAGE>

sented to such waiver and attaching copies of such consents. When a Default or
Event of Default is waived, it is cured and ceases.

SECTION 6.05.  Control by Majority.
               -------------------

          The Holders of not less than a majority in principal amount of the
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. Subject to Section 7.01, however, the Trustee may refuse
to follow any direction that conflicts with any law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another
Securityholder, or that may involve the Trustee in personal liability; provided
                                                                       --------
that the Trustee may take any other action deemed proper by the trustee which
is not inconsistent with such direction.

          In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against any loss or expense caused by
taking such action or following such direction.

SECTION 6.06.  Limitation on Suits.
               -------------------

          A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities unless:

          (1)  the Holder gives to the Trustee written notice of a continuing
     Event of Default;

          (2)  the Holder or Holders of at least 25% in principal amount of the
     outstanding Securities make a written request to the Trustee to pursue the
     remedy;

          (3)  such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (4)  the Trustee does not comply with the request within 45 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

          (5)  during such 45-day period the Holder or Holders of a majority in
     principal amount of the outstanding Securities do not give the Trustee a
     direction which, in the opinion of the Trustee, is inconsistent with the
     request.

                                     -74-

<PAGE>

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over such other
Securityholder.

SECTION 6.07.  Rights of Holders To Receive Payment.
               ------------------------------------

          Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of principal of and interest on a Security, on or
after the respective due dates expressed in such Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of the Holder.

SECTION 6.08.  Collection Suit by Trustee.

fees and expenses of such counsel; provided, however, that the Company will not
                                   --------  -------

     irrevocably instructed to apply such U.S. Legal Tender to the payment of
     said principal, premium, if any, and interest with respect to the
     Securities and provided, further, that from and after the time of deposit,
                    --------  -------

     discharge does not result in a default under the Credit Agreement or any
     other material agreement or instrument then known to such counsel that
     binds or affects the Company.

          Subject to the next sentence and notwithstanding the foregoing
paragraph, the Company's obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01,

and Section 4.02 hereof, (iii) the rights, powers, trusts, duties and immunities

          (c)  Upon the Company's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.03 hereof, be released
from its obligations under the covenants contained in Sections 4.03, 4.04 and
Sections 4.12 through 4.19 and Article Five hereof with respect to the
outstanding Securities on and after the date the conditions set forth below are
satisfied (hereinafter, "Covenant Defeasance"), and the Securities shall
                         -------------------
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Securities shall not be deemed outstanding for accounting purposes) and Holders
of the Securities and any amounts deposited under Section 8.03 hereof shall
cease to be subject to any obligations to, or the rights of, any holder of
Senior Debt under Article Ten or otherwise. For this purpose, such Covenant
Defeasance means that, with respect to the outstanding Securities, the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.01(c) hereof, but, except as specified
above, the remainder of this Indenture and such Securities shall be unaffected
thereby. In addition, upon the Company's exercise under paragraph (a) hereof of
the option applicable to this paragraph (c), subject to the satisfaction of the
conditions set forth in Section 8.03 hereof, Sections 6.01(c), 6.01(d) and
6.01(e) shall not constitute Events of Default.

SECTION 8.03.  Conditions to Legal Defeasance or Covenant Defeasance.
               -----------------------------------------------------

          The following shall be the conditions to the application of either

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (a)  the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders, U.S. Legal Tender or U.S. Government
     Obligations or a combina-

                                     -87-
<PAGE>

tion thereof which through the scheduled payment of principal and interest in
respect thereof in accordance with their terms, will provide, not later than one
day before the due date of any payment on the Securities, U.S. Legal Tender in
such amounts as will be sufficient, in the opinion of a nationally recognized
firm of independent public accountants, to pay the principal of, premium, if
any, and interest on the Securities on the stated date for payment thereof or on
the applicable redemption date, as the case may be;

     (b)  in the case of an election under Section 8.02(b) hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred;

     (c)  in the case of an election under Section 8.02(c) hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
Securities will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

     (d)  no Default or Event of Default shall have occurred and be continuing
on the date of such deposit (other than a Default or Event of Default resulting
from the incurrence of Indebtedness all or a portion of the proceeds of which
will be used to defease the Securities pursuant to this Article Eight
concurrently with such incurrence) or insofar as Sections 6.01(f) and 6.01(g)
hereof are concerned, at any time in the period ending on the 91st day after the
date of such deposit;

                                     -88-
<PAGE>

          (e)  such legal Defeasance or Covenant Defeasance shall not result in
     a breach or violation of, or constitute a default under this Indenture, the
     Credit Agreement or any other material agreement or instrument to which the
     Company or any of its Subsidiaries is a party of by which the Company or
     any of its Subsidiaries is bound;

          (f)  the Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders over any other creditors of the Company or
     with the intent of defeating, hindering, delaying or defrauding any other
     creditors of the Company or others;

          (g)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for or relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with; and

          (h)  the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that (i) the trust funds will not be subject to any
     rights of any holders of Senior Debt, including, without limitation, those
     arising under this Indenture, and (ii) assuming no intervening bankruptcy
     or insolvency of the Company between the date of deposit and the 91st day
     following the deposit and that no Holder is an insider of the Company,
     after the 91st day following the deposit, the trust funds will not be
     subject to the effect of any applicable Bankruptcy Law.

          Notwithstanding the foregoing, the Opinion of Counsel required by
clause (b) above of this Section 8.03 with respect to a Legal Defeasance need
not be delivered if all Securities not theretofore delivered to the Trustee for
cancellation (i) have become due and payable or (ii) will become due and payable
on the Maturity Date within one year under arrangements satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.

SECTION 8.04. Application of Trust Money.
              --------------------------

          The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or
U.S. Government Obligations deposited with it pursuant to this Article Eight,
and shall apply the deposited U.S. Legal Tender and the money from U.S.
Government Obligations in accordance with this Indenture to the payment of
principal of and interest on the Securities. The Trustee shall be

                                     -89-



<PAGE>

under no obligation to invest said U.S. Legal Tender or U.S. Government
Obligations except as it may agree with the Company.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Legal Tender or U.S.
Government Obligations deposited pursuant to Section 8.03 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the
outstanding Securities.

          Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the
Company's request any U.S. Legal Tender or U.S. Government Obligations held by
it as provided in Section 8.03 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

SECTION 8.05. Repayment to the Company.
              ------------------------

          Subject to this Article Eight, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess U.S. Legal Tender or U.S.
Government Obligations held by them at any time and thereupon shall be relieved
from all liability with respect to such money. The Trustee and the Paying Agent
shall pay to the Company upon request any money held by them for the payment of
principal or interest that remains unclaimed for two years; provided that the
                                                            --------
Trustee or such Paying Agent, before being required to make any payment, may at
the expense of the Company cause to be published once in a newspaper of general
circulation in the City of New York or mail to each Holder entitled to such
money notice that such money remains unclaimed and that after a date specified
therein which shall be at least 30 days from the date of such publication or
mailing any unclaimed balance of such money then remaining will be repaid to the
Company. After payment to the Company, Holders entitled to such money must look
to the Company for payment as general creditors unless an applicable law
designates another Person.

SECTION 8.06. Reinstatement.
              -------------

          If the Trustee or Paying  Agent is unable to apply any U.S. Legal
Tender or U.S. Government Obligations in accordance

                                     -90-
<PAGE>

with this Article Eight by reason of any legal proceeding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Eight until such time as the
Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S.
Government Obligations in accordance with this Article Eight; provided that if
                                                              --------
the Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying
Agent.

SECTION 9.01.  Without Consent of Holders.
               --------------------------

          Subject to Section 9.03, the Company, the Guarantors and the Trustee,
together, may amend or supplement this Indenture, the Securities or the

          (1)  to cure any ambiguity, defect or inconsistency;

          (5)  to comply with any requirements of the Commission in connection
     with the qualification of this Indenture under the TIA; or

                                     -91-




<PAGE>

          (6)  to add or release any Guarantor pursuant to the terms of this
     Indenture;

provided that the Company has delivered to the Trustee an Opinion of Counsel and
- --------
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.01.

SECTION 9.02. With Consent of Holders.
              -----------------------

          Subject to Sections 6.07 and 9.03, the Company, the Guarantors and the
Trustee, together, with the written consent of the Holder or Holders of at least
a majority in aggregate principal amount of the outstanding Securities, may
amend or supplement this Indenture, the Securities or the Guarantees, without
notice to any other Securityholders. Subject to Sections 6.07 and 9.03, the
Holder or Holders of a majority in aggregate principal amount of the outstanding
Securities may waive compliance by the Company with any provision of this
Indenture, the Securities or the Guarantees without notice to any other
Securityholder. Without the consent of each Securityholder affected, however, no
amendment, supplement or waiver, including a waiver pursuant to Section 6.04,
may:

          (1)  reduce the amount of Securities whose Holders must consent to an
     amendment, supplement or waiver;

          (2)  reduce the rate of or change or have the effect of changing the
     time for payment of interest, including default interest, on any

          (3)  reduce the principal of or change or have the effect of changing
     the fixed maturity of any Securities, or change the date on which any

     redemption or purchase price therefor;

          (4)  make any Securities payable in money other than that stated in
     the Securities;

          (5)  make any change in provisions of this Indenture protecting the
     right of each Holder to receive payment of principal of and interest on
     such Security on or after the due date thereof or to bring suit to enforce
     such payment, or permitting Holders of a majority in principal amount of
     the Securities to waive Defaults or Events of Default;

                                     -92-
<PAGE>

          (6)  modify or change any provision of this Indenture or the related
     definitions affecting the subordination or ranking of the Securities or any
     Guarantee, in a manner which adversely affects the Holders;

          (7)  after the Company's obligation to purchase Securities arises
     thereunder, amend, modify or change in any material respect the obligation
     of the Company to make and consummate a Change of Control Offer in the
     event of a Change of Control or make and consummate a Net Proceeds Offer
     with respect to any Asset Sale that has been consummated, or modify any of
     the provisions or definitions with respect thereto; or

          (8)  release any Guarantor that is a Significant Subsidiary from any
     of its obligations under its Guarantee or this Indenture otherwise than in
     accordance with the terms of this Indenture.

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03. Effect on Senior Debt.
              ---------------------

          No amendment of, or supplement or waiver to, this Indenture shall
adversely affect the rights of any holder of Senior Debt or Guarantor Senior
Debt under Article Ten or Article Twelve, as the case may be, of this Indenture,
without the consent of such holder.

SECTION 9.04. Compliance with TIA.
              -------------------

          From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture, the Securities or the
Guarantees shall comply with the TIA as then in effect.

                                     -93-
<PAGE>

SECTION 9.05. Revocation and Effect of Consents.
              ---------------------------------

          Until an amendment, waiver or supplement becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of his Security by notice to the Trustee
or the Company received before the date on which the Trustee receives an
Officers' Certificate certifying that the Holders of the requisite principal
amount of Securities have consented (and not theretofore revoked such consent)
to the amendment, supplement or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver which record date shall be at least 30 days prior to the
first solicitation of such consent. If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to revoke any consent previously
given, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 90 days after
such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (9) of Section 9.02, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security; provided that any such waiver
                                                   --------
shall not impair or affect the right or any Holder to receive payment of
principal of and interest on a Security, on or after the respective due dates
expressed in such Security, or to bring suit for the enforcement of any such
payment on or after such respective dates without the consent of such Holder.

SECTION 9.06. Notation on or Exchange of Securities.
              -------------------------------------

          If an amendment, supplement or waiver changes the terms of a Security,
the Company may require the Holder of the Security to deliver it to the Trustee.
The Company shall provide the Trustee with an appropriate notation on the
Security

                                     -94-


<PAGE>

about the changed terms and cause the Trustee to return it to the Holder at the
Company's expense.  Alternatively, if the Company or the Trustee so determines,
the Company in exchange for the Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.  Failure to make
the appropriate notation or issue a new Security shall not affect the validity
and effect of such amendment, supplement or waiver.


SECTION 9.07.  Trustee To Sign Amendments, Etc.
               -------------------------------

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article Nine; provided that the Trustee may, but
                                          --------
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
each stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and constituted the legal, valid and binding obligations of the
Company enforceable in accordance with its terms. Such Opinion of Counsel shall
be at the expense of the Company.


                                  ARTICLE TEN

                          SUBORDINATION OF SECURITIES


SECTION 10.01. Securities Subordinated to Senior Debt.
               ---------------------------------------

          Anything herein to the contrary notwithstanding, the Company, for
itself and its successors, and each Holder, by his or her acceptance of
Securities, agrees that the payment of all Obligations owing to the Holders in
respect of the Securities is subordinated, to the extent and in the manner
provided in this Article Ten, to the prior payment in full in cash of Cash
Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, of all Obligations on Senior Debt (including the
Obligations with respect to the Credit Agreement). Notwithstanding the
foregoing, payments and distributions made relating to the Notes pursuant to the
trust described under Article Eight shall not, so long as the conditions
specified in Article Eight (without any waiver or modification of the
requirement that the deposits pursuant thereto do

                                     -95-

<PAGE>

not conflict with the terms of the Credit Agreement or any other Senior Debt or
Guarantor Senior Debt) are satisfied on the date of any deposit pursuant to said
trust, be so subordinated in right of payment.

          This Article Ten shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Senior Debt, and such provisions are
made for the benefit of the holders of Senior Debt and such holders are made
obligees hereunder and any one or more of them may enforce such provisions.

SECTION 10.02. Suspension of Payment When Senior Debt Is in Default.
               ----------------------------------------------------

          (a)  If any default occurs and is continuing in the payment when due,
whether at maturity, upon any redemption, by declaration or otherwise, of any
principal of, interest on, unpaid drawings for letters of credit issued in
respect of, or regularly accruing fees with respect to, any Senior Debt (a
"Payment Default"), then no payment or distribution of any kind or character
 ---------------
shall be made by or on behalf of the Company or any other Person on its or their
behalf with respect to any Obligations on or relating to the Securities or to
acquire any of the Securities for cash or property or otherwise.

          (b)  If any other event of default (other than a Payment Default)
occurs and is continuing with respect to any Designated Senior Debt (as such
event of default is defined in the instrument creating or evidencing such
Designated Senior Debt) permitting the holders of such Designated Senior Debt
then outstanding to accelerate the maturity thereof (a "Non-payment Default")
                                                        -------------------
and if the Representative for the respective issue of Designated Senior Debt
gives notice of the event of default to the Trustee stating that such notice is
a payment blockage notice (a "Payment Blockage Notice"), then, unless and until
                              -----------------------
all events of default have been cured or waived or have ceased to exist or the
Trustee receives notice thereof from the Representative for the respective issue
of Designated Senior Debt terminating the Payment Blockage Period (as defined
below), during the 180 days after the delivery of such Payment Blockage Notice
(the "Payment Blockage Period"), neither the Company nor any other Person on its
      -----------------------
behalf shall (x) make any payment of any kind or character with respect to any
Obligations on or with respect to the Securities or (y) acquire any of the
Securities for cash or property or otherwise. Notwithstanding anything herein to
the contrary, (x) in no event will a Payment Blockage Period extend beyond 180
days from the date the applicable Payment Blockage Notice is received by the
Trustee and (y) only

                                     -96-
<PAGE>

one such Payment Blockage Period may be commenced within any 360 consecutive
days. For all purposes of this Section 10.02(b), no event of default which
existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Debt shall be, or be made,
the basis for the commencement of a second Payment Blockage Period by the
Representative of such Designated Senior Debt whether or not within a period of
360 consecutive days, unless such event of default shall have been cured or
waived for a period of not less than 90 consecutive days (it being acknowledged
that any subsequent action, or any breach of any financial covenants for a
period commencing after the date of commencement of such Payment Blockage that,
in either case, would give rise to an event of default pursuant to any
provisions under which an event of default previously existed or was continuing
shall constitute a new event of default for this purpose).

     (c) In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any Holder when such payment is prohibited by the
foregoing provisions of this Section 10.02, such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Senior Debt (pro rata to such holders on the basis of the respective amount of
Senior Debt held by such holders) or their respective Representatives), as their
respective interests may appear. The Trustee shall be entitled to rely on
information regarding amounts then due and owing on the Senior Debt, if any,
received from the holders of Senior Debt (or their Representatives) or, if such
information is not received from such holders or their Representatives, from the
Company and only amounts included in the information provided to the Trustee
shall be paid to the holders of Senior Debt.

     Nothing contained in this Article Ten shall limit the right of the Trustee
or the Holders of Securities to take any action to accelerate the maturity of
the Securities pursuant to Section 6.02 or to pursue any rights or remedies
hereunder; provided that all Senior Debt thereafter due or declared to be
           --------
due shall first be paid in full in cash or Cash Equivalents before the Holders
are entitled to receive any payment of any kind or character with respect to
Obligations on the Securities.

SECTION 10.03. Securities Subordinated to Prior Payment of All Senior Debt on
               Dissolution, Liquidation or Reorganization of Company.
               --------------------------------------------------------------

          (a)  Upon any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to creditors upon
any total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets of the Company
or in a bankruptcy, reorganization, insolvency, receivership or other similar
proceeding relating to the Company or its property, whether voluntary or
involuntary , all Obligations due or to become due upon all Senior Debt shall
first be paid in full in cash or Cash Equivalents, or such payment duly provided
for to the satisfaction of the holders of Senior Debt, before any payment or
distribution of any kind or character is made on account of any Obligations on
or relating to the Securities, or for the acquisition of any of the Securities
for cash or property or otherwise. Upon any such dissolution, winding-up,
liquidation, reorganization, receivership or similar proceeding, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders or the Securities of the Trustee
under this Indenture would be entitled, except for the provisions hereof, shall
be paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the
Holders or by the Trustee under this Indenture if received by them, directly to
the holders of Senior Debt (pro rata to such holders on the basis of the
respective amounts of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of Senior Debt remaining
unpaid until all such Senior Debt has been paid in full in cash or Cash
Equivalents after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of Senior Debt.

     (b)  To the extent any payment of Senior Debt (whether by or on behalf of
the Company, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or
other similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then, if such payment is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or

                                     -98-
<PAGE>

other similar Person, the Senior Debt or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

     (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 10.03, such payment or distribution
shall be held in trust for the benefit of, and shall be paid over or delivered
to, the holders of Senior Debt (pro rata to such holders on the basis of the
respective amount of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of Senior Debt remaining
unpaid until all such Senior Debt has been paid in full in cash or Cash
Equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Debt.

     (d) The consolidation of the Company with, or the merger of the Company
with or into, another corporation, partnership, trust or limited liability
company or the liquidation or dissolution of the Company following the
conveyance or transfer of all or substantially all of its assets, to another
corporation, partnership, trust or limited liability company upon the terms and
conditions provided in Article Five hereof and as long as permitted under the
terms of the Senior Debt shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section if such other
corporation shall, as a part of such consolidation, merger, conveyance or
transfer, assume the Company's obligations hereunder in accordance with Article
Five hereof.

SECTION 10.04. Payments May Be Paid Prior
               to Dissolution.
               --------------------------

          Nothing contained in this Article Ten or elsewhere in this Indenture
shall prevent (i) the Company, except under the conditions described in Sections
10.02 and 10.03, from making payments at any time for the purpose of making
payments of principal of and interest on the Securities, or from depositing with
the Trustee any moneys for such payments, or (ii) in the absence of actual
knowledge by the Trustee that a given payment would be prohibited by Section
10.02 or 10.03, the application by the Trustee of any moneys deposited with it
for the purpose of making such payments of principal of, and interest on, the

                                     -99-

<PAGE>

Securities to the Holders entitled thereto unless at least two Business Days
prior to the date upon which such payment would otherwise become due and payable
a Trust Officer shall have actually received the written notice provided for in
the first sentence of Section 10.02(b) or in Section 10.07 (provided that,
                                                            --------
notwithstanding the foregoing, the Holders receiving any payments made in
contravention of Section 10.02 and/or 10.03 (and the respective such payments)
shall otherwise be subject to the provisions of Section 10.02 and Section
10.03). The Company shall give prompt written notice to the Trustee of any
dissolution, winding-up, liquidation or reorganization of the Company, although
any delay or failure to give any such notice shall have no effect on the
subordination provisions contained herein.

SECTION 10.05.  Holders To Be Subrogated to Rights of Holders of Senior Debt.
                ------------------------------------------------------------

          Subject to the payment in full in cash or Cash Equivalents of all
Senior Debt, the Holders of the Securities shall be subrogated to the rights of
the holders of Senior Debt to receive payments or distributions of cash,
property or securities of the Company applicable to the Senior Debt until the
Securities shall be paid in full; and, for the purposes of such subrogation, no
such payments or distributions to the holders of the Senior Debt by or on behalf
of the Company, or by or on behalf of the Holders by virtue of this Article Ten,
which otherwise would have been made to the Holders shall, as between the
Company and the Holders, be deemed to be a payment by the Company to or on
account of the Senior Debt, it being understood that the provisions of this
Article Ten are and are intended solely for the purpose of defining the relative
rights of the Holders, on the one hand, and the holders of Senior Debt, on the
other hand.

SECTION 10.06.  Obligations of the Company Unconditional.
                ----------------------------------------

          Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Debt, and the Holders, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders and creditors of the Company
other than the holders of the Senior Debt, nor shall anything herein or therein
prevent the Holder of any Security or the Trustee on

                                     -100-





<PAGE>

its behalf from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, in respect of
cash, property or securities of the Company received upon the exercise of
any such remedy.

SECTION 10.07. Notice to Trustee.
               -----------------

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities pursuant to the provisions of this Article
Ten, although any delay or failure to give any such notice shall have no effect
on the subordination provisions contained herein.  Regardless of anything to the
contrary contained in this Article Ten or elsewhere in this Indenture, the
Trustee shall not be charged with knowledge of the existence of any default or
event of default with respect to any Senior Debt or of any other facts which
would prohibit the making of any payment to or by the Trustee unless and until
the Trustee shall have received notice in writing from the Company, or from a
holder of Senior Debt or a Representative therefor and, prior to the receipt of
any such written notice, the Trustee shall be entitled to assume (in the absence
of actual knowledge to the contrary) that no such facts exist.  The Trustee
shall be entitled to rely on the delivery to it of any notice pursuant to
this Section 10.07 to establish that such notice has been given by a holder of
Senior Debt (or a trustee thereof).

     In the event that the Trustee determines in good faith that any evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article Ten, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amounts of Senior Debt held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article Ten, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

SECTION 10.08.  Reliance on Judicial Order or
                Certificate of Liquidation Agent.
                --------------------------------

     Upon any payment or distribution of assets of the Company referred to in
this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Securities shall be entitled to rely upon any
order or de-

                                     -101-








<PAGE>

cree made by any court of competent jurisdiction in which any insolvency,
bankruptcy, receivership, dissolution, winding-up, liquidation, reorganization
or similar case or proceeding is pending, or upon a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered
to the Trustee or the Holders of the Securities, for the purpose of ascertaining
the persons entitled to participate in such payment or distribution, the holders
of the Senior Debt and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Ten.

SECTION 10.09.  Trustee's Relation to Senior Debt.
                ---------------------------------

     The Trustee and any agent of the Company or the Trustee shall be entitled
to all the rights set forth in this Article Ten with respect to any Senior Debt
which may at any time be held by it in its individual or any other capacity to
the same extent as any other holder of Senior Debt and nothing in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such
holder.

     With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt.

     Whenever a distribution is to be made or a notice given to holders or
owners of Senior Debt, the distribution may be made and the notice may be given
to their Representative, if any.

SECTION 10.10.  Subordination Rights Not Impaired
                by Acts or Omissions of the Company
                or Holders of Senior Debt.
                -----------------------------------

     No right of any present or future holders of any Senior Debt to enforce
subordination as provided herein shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms of this Indenture,

                                     -102-












<PAGE>

regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Securities and without impairing or releasing the
subordination provided in this Article Ten or the obligations hereunder of the
Holders of the Securities to the holders of the Senior Debt, do any one or more
of the following: (i) change the manner, place or terms of payment or extend
the time of payment of, or renew or alter, Senior Debt, or otherwise amend or
supplement in any manner Senior Debt, or any instrument evidencing the same or
any agreement under which Senior Debt is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

SECTION 10.11. Securityholders Authorize Trustee To Effectuate Subordination
               -------------------------------------------------------------
               of Securities.
               -------------

          Each Holder of Securities by its acceptance of them authorizes and
expressly directs the Trustee on its behalf to take such action as may be
necessary or appropriate to effectuate, as between the holders of Senior Debt
and the Holders of Securities, the subordination provided in this Article Ten,
and appoints the Trustee its attorney-in-fact for such purposes, including, in
the event of any dissolution, winding-up, liquidation or reorganization of the
Company (whether in bankruptcy, insolvency, receivership, reorganization or
similar proceedings or upon an assignment for the benefit of credits or
otherwise) tending towards liquidation of the business and assets of the
Company, the filing of a claim for the unpaid balance of its Securities and
accrued interest in the form required in those proceedings.

          If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Securities. Nothing herein contained shall be deemed to
authorize the Trustee or

                                     -103-


<PAGE>

the holders of Senior Debt or their Representative to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of
any Holder thereof, or to authorize the Trustee or the holders of Senior Debt or
their Representative to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 10.12. This Article Ten Not To Prevent Events of Default.
               -------------------------------------------------

          The failure to make a payment on account of principal of or interest
on the Securities by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of an Event of Default.

SECTION 10.13. Trustee's Compensation Not Prejudiced.
               -------------------------------------

          Nothing in this Article Ten will apply to amounts due to the Trustee
pursuant to other sections of this Indenture.

                                ARTICLE ELEVEN

                            GUARANTEE OF SECURITIES

SECTION 11.01. Unconditional Guarantee.
               -----------------------

          Subject to the provisions of this Article Eleven, each of the
Guarantors hereby, jointly and severally, unconditionally and irrevocably
guarantees, on a senior subordinated basis (such guarantees to be referred to
herein as a "Guarantee") to each Holder of a Security authenticated and
             ---------
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the
Securities or the obligations of the Company or any other Guarantors to the
Holders or the Trustee hereunder or thereunder, that: (a) the principal of,
premium, if any, and interest on the Securities shall be duly and punctually
paid in full when due, whether at maturity, upon redemption at the option of
Holders pursuant to the provisions of the Securities relating thereto, by
acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Securities and all other
obligations of the Company or the Guarantors to the Holders or the Trustee
hereunder or thereunder (including amounts due the

                                     -104-
<PAGE>

Trustee under Section 7.07 hereof) and all other obligations shall be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any Securities
or any of such other obligations, the same shall be promptly paid in full when
due or performed in accordance with the terms of the extension or renewal,
whether at maturity, by acceleration or otherwise. Failing payment when due of
any amount so guaranteed, or failing performance of any other obligation of the
Company to the Holders under this Indenture or under the Securities, for
whatever reason, each Guarantor shall be obligated to pay, or to perform or
cause the performance of, the same immediately. An Event of Default under this
Indenture or the Securities shall constitute an event of default under this
Guarantee, and shall entitle the Holders of Securities to accelerate the
obligations of the Guarantors hereunder in the same manner and to the same
extent as the obligations of the Company.

     Each of the Guarantors hereby agrees that its obligations hereunder shall
be unconditional, irrespective of the validity, regularity or enforceability of
the Securities or this Indenture, the absence of any action to enforce the same,
any waiver or consent by any Holder of the Securities with respect to any
provisions hereof or thereof, any release of any other Guarantor, the recovery
of any judgment against the Company, any action to enforce the same, whether or
not a Guarantee is affixed to any particular Security, or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
Guarantor. Each of the Guarantors hereby waives the benefit of diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the company, protest, notice and all demands whatsoever and covenants
that its Guarantee shall not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and this Guarantee. This
Guarantee is a guarantee of payment and not of collection. If any Holder or the
Trustee is required by any court or otherwise to return to the Company or to any
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or such Guarantor, any amount paid by the
Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect.
Each Guarantor further agrees that, as between it, on the one hand, and the
Holders of Securities and the Trustee, on the other hand, (a) subject to this
Article Eleven, the maturity of the obligations guaranteed

                                     -105-
<PAGE>

hereby may be accelerated as provided in Article Six hereof for the purpose of
this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby,
and (b) in the event of any acceleration of such obligations as provided in
Article Six hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purpose of this
Guarantee.

     No stockholder, officer, director, employee or incorporator, past, present
or future, or any Guarantor, as such, shall have any personal liability under
this Guarantee by reason of his, her or its status as such stockholder, officer,
director, employee or incorporator.

     Each Guarantor that makes a payment or distribution under its Guarantee
shall be entitled to a contribution from each other Guarantor, determined in
accordance with GAAP.

SECTION 11.02. Limitations on Guarantees.
               -------------------------

     The obligations of each Guarantor under its Guarantee are limited to the
maximum amount which, after giving effect to all other contingent and fixed
liabilities of such Guarantor (including without limitation, its guarantee of
Obligations pursuant to the Credit Agreement and any other Guarantor Senior
Debt) and after giving effect to any collections from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other
Guarantor under its Guarantee or pursuant to its contribution obligations under
this Indenture, will result in the obligations of such Guarantor under the
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal or state law. Each Guarantor that makes a payment or distribution under
a Guarantee shall be entitled to a contribution from each other Guarantor in an
amount pro rata, based on the net assets of each Guarantor, determined in
       --- ----
accordance with GAAP.

SECTION 11.03. Execution and Delivery of Guarantee.
               -----------------------------------

     To further evidence the Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Guarantee, substantially in the
form of Exhibit E hereto, shall be endorsed on each Security authenticated and
        ---------
delivered by the Trustee. Such Guarantee shall be executed on behalf of each
Guarantor by either manual or facsimile signature of one Officer of each
Guarantor who shall have been duly authorized to so execute by all requisite
corporation action. The valid-

                                     -106-
<PAGE>

ity and enforceability of any Guarantee shall not be affected by the fact that
it is not affixed to any particular Security.

     Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 11.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Security a notation of such Guarantee.

     If an Officer of a Guarantor whose signature is on this Indenture or a
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Security shall nevertheless be valid.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of each Guarantor.

SECTION 11.04. Release of a Guarantor.
               ----------------------

     (a)  Upon the sale or disposition of all of the Capital Stock of a
Guarantor by the Company, in a transaction or series of related transactions
that either (i) does not constitute an Asset Sale or (ii) constitutes an Asset
Sale the Net Cash Proceeds of which are applied in accordance with Section 4.16,
or upon the consolidation or merger of a Guarantor with or into any Person in
compliance with Article Five (in each case, other than to the Company or an
Affiliate of the Company), or if any Guarantor is dissolved or liquidated in
accordance with this Indenture, such Guarantor's Guarantee will be automatically
discharged and released from all obligations under this Article Eleven without
any further action required on the part of the Trustee or any Holder. Any
Guarantor not so released or the entity surviving such Guarantor, as applicable,
shall remain or be liable under its Guarantee as provided in this Article
Eleven.

     (b)  The Trustee shall deliver an appropriate instrument evidencing the
release of a Guarantor upon receipt of a request by the Company or such
Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel
certifying as to the compliance with this Section 11.04; provided, however, that
                                                         --------  -------
the legal counsel delivering such Opinion of Counsel may rely as to matters of
fact on one or more Officers' Certificates of the Company.

                                     -107-
<PAGE>

     The Trustee shall execute any documents reasonably requested by the Company
or a Guarantor in order to evidence the release of such Guarantor from its
obligations under its Guarantee endorsed on the Securities and under this
Article Eleven.

     Except as set forth in Articles Four and Five and this Section 11.04,
nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of a Guarantor with or into the Company or another
Guarantor or shall prevent any sale or conveyance of the property of a Guarantor
as an entirety or substantially as an entirety to the Company or another
Guarantor.

SECTION 11.05. Waiver of Subrogation.
               ---------------------

     Until this Indenture is discharged and all of the Securities are discharged
and paid in full, each Guarantor hereby irrevocably waives and agrees not to
exercise any claim or other rights which it may now or hereafter acquire against
the Company that arise from the existence, payment, performance or enforcement
of the Company's obligations under the Securities or this Indenture and such
Guarantor's obligations under this Guarantee and this Indenture, in any such
instance including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution, indemnification, and any right to participate in any
claim or remedy of the Holders against the Company, whether or not such claim,
remedy or right arises in equity, or under contract, statute or common law,
including, without limitation, the right to take or receive from the Company,
directly or indirectly, in cash or other property or by set-off or in any other
manner, payment or security on account of such claim or other rights. If any
amount shall be paid to any Guarantor in violation of the preceding sentence and
any amounts owing to the Trustee or the Holders of Securities under the
Securities, this Indenture, or any other document or instrument delivered under
or in connection with such agreements or instruments, shall not have been paid
in full, such amount shall have been deemed to have been paid to such Guarantor
for the benefit of, and held in trust for the benefit of, the Trustee or the
Holders and shall forthwith be paid to the Trustee for the benefit of itself or
such Holders to be credited and applied to the obligations in favor of the
Trustee or the Holders, as the case may be, whether matured or unmatured, in
accordance with the terms of this Indenture. Each Guarantor acknowledges that it
will receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture

                                     -108-
<PAGE>

and that the waiver set forth in this Section 11.05 is knowingly made in
contemplation of such benefits.

SECTION 11.06. Immediate Payment.
               -----------------

          Each Guarantor agrees to make immediate payment to the Trustee on
behalf of the Holders of all Obligations owing or payable to the respective
Holders upon receipt of a demand for payment therefor by the Trustee to such
Guarantor in writing.

SECTION 11.07. No Set-Off.
               ----------

          Each payment to be made by a Guarantor hereunder in respect of the
Obligations shall be payable in the currency or currencies in which such
Obligations are denominated, and shall be made without set-off, counterclaim,
reduction or diminution of any kind or nature.

SECTION 11.08. Obligations Absolute.
               ---------------------

          The obligations of each Guarantor hereunder are and shall be absolute
and unconditional and any monies or amounts expressed to be owing or payable by
each Guarantor hereunder which may not be recoverable from such Guarantor on the
basis of a Guarantee shall be recoverable from such Guarantor as a primary
obligor and principal debtor in respect thereof.

SECTION 11.09. Obligations Continuing.
               ----------------------

          The obligations of each Guarantor hereunder shall be continuing and
shall remain in full force and effect until all the obligations have been paid
and satisfied in full. Each Guarantor agrees with the Trustee that it will from
time to time deliver to the Trustee suitable acknowledgments of this continued
liability hereunder and under any other instrument or instruments in such form
as counsel to the Trustee may advise and as will prevent any action brought
against it in respect of any default hereunder being barred by any statute of
limitations now or hereafter in force and, in the event of the failure of a
Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and
agent of such Guarantor to make, execute and deliver such written acknowledgment
or acknowledgments or other instruments as may from time to time become
necessary or advisable, in the judgment of the Trustee on the advice of counsel,
to fully maintain and keep in force the liability of such Guarantor hereunder.

                                     -109-
<PAGE>

SECTION 11.10. Obligations Not Reduced.
               -----------------------

          The obligations of each Guarantor hereunder shall not be satisfied,
reduced or discharged solely by the payment of such principal, premium, if any,
interest, fees and other monies or amounts as may at any time prior to discharge
of this Indenture pursuant to Article Eight be or become owing or payable under
or by virtue of or otherwise in connection with the Securities or this
Indenture.

SECTION 11.11. Obligations Reinstated.
               ----------------------

          The obligations of each Guarantor hereunder shall continue to be
effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of any Guarantor hereunder
(whether such payment shall have been made by or on behalf of the Company or by
or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders
upon the insolvency, bankruptcy, liquidation or reorganization of the Company or
any Guarantor or otherwise, all as though such payment had not been made. If
demand for, or acceleration of the time for, payment by the Company is stayed

whatsoever, occurring before, upon or after any demand for payment hereunder
(and whether or not known or consented to by any Guarantor or any of the
Holders) which, but for this provision, might constitute a whole or partial
defense to a claim against any Guarantor hereunder or might operate to release
or otherwise exonerate any Guarantor from any of its obligations hereunder or
otherwise affect such obligations, whether occasioned by default of any of the
Holders or otherwise, including, without limitation:

          (a)  any limitation of status or power, disability, incapacity or
other circumstance relating to the Company or any other Person, including any

Obligations or the obligations of a Guarantor under its Guarantee; and

     (j)  any other circumstance, including release of the Guarantor pursuant to

constitute a legal or equitable discharge or defense of the Com-

SECTION  12.01.  Guarantee Obligations Subordinated
                 to Guarantor Senior Debt.
                 ----------------------------------

          Anything herein to the contrary notwithstanding, each of the
Guarantors, for itself and its successors, and each Holder, by his or her
acceptance of Guarantees, agrees that the payment of all Obligations owing to
the Holders in respect of its Guarantee (collectively, as to any Guarantor, its
"Guarantee Obligations") is subordinated, to the extent and in the manner
 ---------------------
provided in this Article Twelve, to the prior payment in full in cash or Cash
Equivalents, or such payment duly provided for to the satisfaction of the
holders of Guarantor Senior Debt, of all Obligations on Guarantor Senior Debt of
such Guarantor.

          This Article Twelve shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Guarantor Senior Debt, and such
provisions are made for the benefit of the holders of Guarantor Senior Debt and
such holders are made obligees hereunder and any one or more of them may enforce
such provisions.


SECTIONS  12.02.  Suspension of Guarantee Obligations
                  When Guarantor Senior Debt Is in Default.
                  ----------------------------------------

          (a)     If any default occurs and is continuing in the payment when
due, whether at maturity, upon any redemption, by declaration or otherwise, of
any principal of, interest on, unpaid drawings for letters of credit issued in
respect of, or regularly accruing fees with respect to, any Guarantor Senior
Debt, then no payment of any kind or character shall be made by or on behalf of
such Guarantor or any other Person on its behalf with respect to any Guarantee
Obligations or to acquire any of the Securities for cash or property or
otherwise and un-

                                     -115-

til such Payment Default shall have been cured or waived or shall have ceased to
exist or such Guarantor Senior Debt shall have been discharged or paid in full
in cash or Cash Equivalents.

          (b)    At any time while any Payment Blockage Period is in existence,
neither any Guarantor nor any other Person on any Guarantor's behalf shall (x)
make any payment of any kind or character with respect to any Obligations on its
Guarantee or (y) acquire any of the Securities for cash or otherwise.

          (c)    In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any Holder when such payment is prohibited
by the foregoing provisions of this Section 12.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Guarantor Senior Debt (pro rata to such holders on the basis of the respective
amount of Guarantor Senior Debt held by such holders) or their respective
Representatives, as their respective interests may appear. The Trustee shall be
entitled to rely on information regarding amounts then due and owing on the
Guarantor Senior Debt, if any, received from the holders of Guarantor Senior
Debt (or their Representatives) or, if such information is not received from
such holders or their Representatives, from a Guarantor and only amounts
included in the information provided to the Trustee shall be paid to the holders
of Guarantor Senior Debt.

SECTION  12.03.  Guarantee Obligations Subordinated
                 to Prior Payment of All Guarantor
                 Senior Debt on Dissolution, Liquidation
                 or Reorganization of Such Guarantor.
                 ---------------------------------------

          (a)    Upon any payment or distribution of assets of any Guarantor of
any kind or character, whether in cash, property or securities, to creditors
upon any total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets of such
Guarantor or in a bankruptcy, reorganization, insolvency, receivership or other
similar proceeding relating to such Guarantor or its property, whether voluntary
or involuntary, all Obligations due or to become due upon all Guarantor Senior
Debt shall first be paid in full in cash or Cash Equivalents, or such payment
duly provided for to the satisfaction of the holders of Guarantor Senior Debt,
before any payment or distribution of any kind or character is made on account
of any Guarantee Obligations or for the acquisition of any of the Securities for
cash or property or otherwise. Upon any such dissolution,

                                     -116-

payment or distribution of assets of such Guarantor of any kind or character,
whether in cash, property or securities, to which the Holders or the Trustee
under this Indenture would be entitled, except for the  provisions hereof,
shall be paid by such Guarantor or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Holders or by the Trustee under this Indenture if received by them,
directly to the holders of Guarantor Senior Debt (pro rata to such holders on
the basis of the respective amounts of Guarantor Senior Debt held by such
holders) or their respective Representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Guarantor Senior Debt may have
been issued, as their respective interests may appear, for application to the
payment of Guarantor Senior Debt remaining unpaid until all such Guarantor
Senior Debt has been paid in full in cash or Cash Equivalents after giving
effect to any concurrent payment, distribution or provision therefor to or for
the holders of Guarantor Senior Debt.

          (b)  To the extent any payment of Guarantor Senior Debt (whether by or
on behalf of a Guarantor, as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, the Guarantor Senior Debt or part thereof originally
intended to be satisfied shall be deemed to be reinstated and outstanding as if
such payment had not occurred.

          (c)  In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 12.03, such payment of distribution
shall be held in trust for the benefit of, and shall be paid over or delivered
to, the holders of Guarantor Senior Debt (pro rata to such holders on the basis
of the respective amount of Guarantor Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Guarantor Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of
Guarantor Senior Debt

Guarantor with or into, another corporation or the liquidation or dissolution of
a Guarantor following the conveyance or transfer of all or substantially all of
its assets, to another corporation upon the terms and conditions provided in
Article Five hereof and as long as permitted under the terms of the Guarantor
Senior Debt shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section if such other corporation shall,
as a part of such consolidation, merger, conveyance or transfer, assumes the
Guarantee of such Guarantor hereunder in accordance with Article Five hereof.

SECTION 12.04. Payments May Be Paid Prior to Dissolution.
               ------------------------------------------

          Nothing contained in this Article Twelve or elsewhere in this
Indenture shall prevent (i) any Guarantor, except under the conditions described
in Sections 12.02 and 12.03, from making payments at any time for the purpose of
making payments on Guarantee Obligations, or from depositing with the Trustee
any moneys for such payments, or (ii) in the absence of actual knowledge by the
Trustee that a given payment would be prohibited by Section 12.02 or 12.03, the
application by the Trustee of any moneys deposited with it for the purpose of
making such payments on Guarantee Obligations to the Holders entitled thereto
unless at least two Business Days prior to the date upon which such payment
would otherwise become due and payable a Trust Officer shall have actually
received the written notice provided for in the first sentence of Section
10.02(b) or in Section 12.07 (provided that, notwithstanding the foregoing, the
                              --------

provisions of Section 12.02 and Section 12.03). Each Guarantor shall give prompt
written notice to the Trustee of any dissolution, winding-up, liquidation or
reorganization of such Guarantor, although any delay or failure to give any such
notice shall have no effect on the subordination provisions contained herein.

SECTION 12.05. Holders of Guarantee Obligations To Be Subrogated to Rights of
               --------------------------------------------------------------
               Holders of Guarantor Senior Debt.
               --------------------------------

          Subject to the payment in full in cash or Cash Equivalents of all
Guarantor Senior Debt, the Holders of Guarantee Obligations of any Guarantor
shall be subrogated to the rights of the holders of Guarantor Senior Debt of
such Guarantor to receive payments or distributions of cash, property or
securities of such Guarantor applicable to such Guarantor Senior Debt until all
amounts owing on or in respect of the Guarantee Obligations shall be paid in
full; and, for the purposes of such subrogation, no such payments or
distributions to the holders of such Guarantor Senior Debt by or on behalf of
such Guarantor, or by or on behalf of the Holders by virtue of this Article
Twelve, which otherwise would have been made to the Holders shall, as between
such Guarantor and the Holders, be deemed to be a payment by such Guarantor to
or on account of such Guarantor Senior Debt, it being understood that the
provisions of this Article Twelve are and are intended solely for the purpose of
defining the relative rights of the Holders, on the one hand, and the holders of
Guarantor Senior Debt, on the other hand.

SECTION 12.06. Obligations of the Guarantors Unconditional.
               -------------------------------------------

          Nothing contained in this Article Twelve or elsewhere in this
Indenture or in the Guarantees is intended to or shall impair, as among the
Guarantors, their creditors other than the holders of Guarantor Senior Debt, and
the Holders, the obligation of the Guarantors, which is absolute and
unconditional, to pay to the Holders all amounts due and payable under the
Guarantees as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders and creditors of the Guarantors other than the holders of the Guarantor
Senior Debt, nor shall anything herein or therein prevent any Holder or the
Trustee on its behalf from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
in respect of cash, property or securities of the Guarantors received upon the
exercise of any such remedy.

SECTION 12.07. Notice to Trustee.
               -----------------

<PAGE>

spect of the Guarantees pursuant to the provisions of this Article Twelve,
although any delay or failure to give any such notice shall have no effect on
the subordination provisions contained herein. Regardless of anything to the
contrary contained in this Article Twelve or elsewhere in this Indenture, the
Trustee shall not be charged with knowledge of the existence of any default or
event of default with respect to any Guarantor Senior Debt or of any other facts
which would prohibit the making of any payment to or by the Trustee unless and
until the Trustee shall have received notice in writing from a Guarantor, or
from a holder of Guarantor Senior Debt or a Representative therefor and, prior
to the receipt of any such written notice, the Trustee shall be entitled to
assume (in the absence of actual knowledge to the contrary) that no such facts
exist. The Trustee shall be entitled to rely on the delivery to it of any notice
pursuant to this Section 12.07 to establish that such notice has been given by a
holder of Senior Debt (or a trustee thereof).

     In the event that the Trustee determines in good faith that any evidence is
required with respect to the right of any Person as a holder of Guarantor Senior
Debt to participate in any payment or distribution pursuant to this Article
Twelve, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amounts of Guarantor Senior
Debt held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Twelve, and if such evidence is not
furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

SECTION 12.08.  Reliance on Judicial Order or
                Certificate of Liquidating Agent.
                --------------------------------

     Upon any payment of distribution of assets of a Guarantor referred to in
this Article Twelve, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders shall be entitled to rely upon any order or decree made
by any court of competent jurisdiction in which any insolvency, bankruptcy,
receivership, dissolution, winding-up, liquidation, reorganization or similar
case or proceeding is pending, or upon a certificate of the trustee in
bankruptcy, liquidating trustee, receiver, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered
to the Trustee or the Holders, for the purpose of ascertaining the persons
entitled to participate in such payment or distribu-

                                     -120-

distributed thereon and all other facts pertinent thereto or to this Article
Twelve.

SECTION 12.09.  Trustee's Relation to Guarantor Senior Debt.
                -------------------------------------------

     The Trustee and any agent of a Guarantor or the Trustee shall be entitled
to all the rights set forth in this Article Twelve with respect to any Guarantor
Senior Debt which may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Guarantor Senior Debt and
nothing in this Indenture shall deprive the Trustee or any such agent of any of
its rights as such holder.

     With respect to the holders of Guarantor Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Twelve, and no implied covenants
or obligations with respect to the holders of Guarantor Senior Debt shall be
read into this Indenture against the Trustee.  The Trustee shall not be deemed
to owe any fiduciary duty to the holders of Guarantor Senior Debt.

     Whenever a distribution is to be made or a notice given to holders or
owners of Guarantor Senior Debt, the distribution may be made and the notice may
be given to their Representative, if any.

SECTION 12.10.  Subordination Rights Not Impaired
                by Acts or Omissions of the Guarantors
                or Holders of Guarantor Senior Debt.
                --------------------------------------

     No right of any present or future holders of any Guarantor Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of any Guarantor
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by any Guarantor with the terms of this Indenture, regardless of
any knowledge thereof which any such holder may have or otherwise be charged
with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Guarantor Senior Debt may, at any time and from time to time, without
the consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Securities and without impairing or releasing the
subordination provided in this Article Twelve

                                     -121-

Guarantor Senior Debt, do any one or more of the following: (i) change the

alter, Guarantor Senior Debt, or otherwise amend or supplement in any manner
Guarantor Senior Debt, or any instrument evidencing the same or any agreement
under which Guarantor Senior Debt is outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Guarantor Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Guarantor Senior Debt; and (iv) exercise or refrain
from exercising any rights against the Guarantors and any other Person.

SECTION 12.11. Holders Authorize Trustee To Effectuate
               Subordination of Guarantee Obligations.
               ---------------------------------------

     Each Holder of Guarantee Obligations by its acceptance of them authorizes
and expressly directs the Trustee on its behalf to take such action as may be
necessary or appropriate to effectuate, as between the holders of Guarantor
Senior Debt and the Holders, the subordination provided in this Article Twelve,
and appoints the Trustee its attorney-in-fact for such purposes, including, in
the event of any dissolution, winding-up, liquidation or reorganization of any

aggregate principal amount of up to $400,000,000 of 10 1/2% Senior Subordinated
Notes due 2009 (the "Securities");

     WHEREAS, the Company has entered into an Agreement and Plan of Merger,
dated November 2, 1999, as amended, whereby the Company has agreed to merge with
and into GroupMAC;

     WHEREAS, Section 5.01 of the Indenture provides that upon a merger of the
Company into another person, such as GroupMAC, GroupMAC is required to execute
and deliver to the Trustee a supplemental indenture pursuant to which GroupMAC
shall unconditionally assume all of the Company's obligations under the
Securities on the terms and conditions set forth in the Indenture;

     WHEREAS, pursuant to Section 4.18 of the Indenture, the New Guarantors are
required to execute and deliver to the Trustee a supplemental indenture pursuant
to which they unconditionally guarantee all of the Company's obligations under
the Securities and the Indenture on the terms set forth in the Indenture; and

     WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee, the
Company, the Existing Guarantors, GroupMAC and the New Guarantors are authorized
to execute and deliver this Supplemental Indenture;

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, it is
hereby mutually covenanted and agreed for the equal and ratable benefit of the
holders of the Securities as follows:

     1.  AGREEMENT TO ASSUME.  GroupMAC hereby assumes the due and punctual

Company to be performed or observed; provided, however, that such assumption
shall not become effective until the effective time of the Merger;

     2.  AGREEMENT TO GUARANTEE.  The New Guarantors hereby unconditionally
guarantee GroupMAC's obligations under the Securities on the terms set forth in
the Indenture; provided, however, that such guarantee shall not become effective

as of August 1, 1997 (the "Original Employment Agreement"); and
                           -----------------------------

     WHEREAS, GroupMAC assigned the Original Employment Agreement to the
Company, and Employee became an employee of the Company, effective as of March
1, 1998; and

     WHEREAS, the Company, GroupMAC and Employee desire to amend and restate the
Original Employment Agreement to reflect the effects of the foregoing
assignment, to modify the provisions of the Original Employment Agreement
pertaining to changes of control of GroupMAC, and to make certain other changes;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties hereby amend and restate the Original Employment
Agreement as follows:

     1.   Employment.  The Company hereby agrees to employ Employee and the
          ----------
Employee hereby agrees to work for the Company as its Executive Vice President-
Commercial Group. Employee's principal office shall be in Houston, Texas.
Employee will report to the President of the Company. Subject to consultation
with the President, Employee will have direct supervisory responsibility and
authority for the operations of the Company's commercial/ industrial businesses.
So long as he is employed by the Company, Employee shall devote his skill,
energy and best efforts to the faithful discharge of his duties as an employee
of the Company. In providing services hereunder, Employee shall comply with and
follow all directives, policies, standards and regulations from time to time
established by the Board of Directors of the Company.

     2.   Term of Employment.  Employee's employment by the Company pursuant to
          ------------------
this Agreement shall continue in effect for an initial term of three years from
the date of this Agreement, unless terminated in accordance with Section 7, and
shall be extended from year to year thereafter, unless terminated effective as
of the end of the initial term or any one-year extension thereafter by written
notice from the Company to Employee, or by written notice of Employee to the
Company, delivered not less than 90 days prior to the end of the initial term,
or the anniversary of such one-year extension, as applicable.
<PAGE>

     3.   Representations and Warranties.  Employee represents and warrants that
          ------------------------------
he is under no contractual or other restrictions or obligations that will
significantly limit his activities on behalf of the Company or will prohibit or
limit the disclosure or use of by Employee of any information which directly or
indirectly relates to the nature of the Company or the services to be rendered
by Employee under this Agreement.

     4.   Compensation.  Subject to the provisions of Section 10, Employee will
          ------------
be entitled to the compensation and benefits set forth in this Section 4.

     (a)  During 1998, the Company shall pay Employee an Annual Base Salary,
payable semi-monthly, in equal semi-monthly installments at a rate equal to
$150,000 per year. In each subsequent calendar year during the term of this
Agreement, the Company shall pay to Employee an Annual Base Salary equal to the
greater of (i) his salary for the immediately preceding year or (ii) if
determined otherwise by the Board of Directors, an Annual Base Salary determined
by the Board of Directors following its annual salary and performance review.

     (b)  Employee shall be eligible to receive an annual bonus pursuant to the
incentive compensation program in effect from time to time for executive
employees of GroupMAC. The target bonus of Employee under such program shall not
be less than 90% of Employee's annual salary.

     (c)  All payments of salary and other compensation to Employee shall be
made after deduction of any taxes required to be withheld with respect thereto
under applicable federal and state laws.

     5.   Fringe Benefits; Expenses.  (a)  Employee shall participate in all
          -------------------------
employee benefit plans sponsored by the Company or GroupMAC for its executive
employees, including but not limited to stock bonus, stock purchase and stock
option plans, sick leave and disability leave, health insurance, dental
insurance and pension and/or profit sharing plans; provided, however, that
except as provided below, the nature, amount and limitations of such plans shall
be determined from time to time by the Board of Directors of the Company.

     (b)  The Company will reimburse Employee for all reasonable business
expenses incurred by Employee in the scope of his employment; provided, however,
that Employee must file expense reports with respect to such expenses in
accordance with the Company's policies as are in effect from time to time.

     (c)  Employee shall be entitled to a minimum of three weeks paid vacation
during each calendar year, increasing to four weeks at June 1, 2000, and to paid
holidays and other paid leave set forth in the Company's policies in effect from
time to time. Any vacation not used during a calendar year may not be used
during any subsequent period.

     (d)  The Company will pay all license fees, occupation taxes and reasonable
educational costs and expenses necessary to maintain Employee's good standing
under any professional licenses.

                                       2
<PAGE>

     (e)  The Company shall use reasonable efforts to provide (i) life insurance
payable to Employee's designated beneficiary in an amount at least three times
Employee's Annual Base Salary and (ii) disability insurance on behalf of
Employee which, as a goal, shall provide for salary continuation in the event of
permanent disability in an amount not less than 60% of Employee's Annual Base
Salary, it being acknowledged by Employee that GroupMAC's present disability
insurance provides a limit of $5,000 per month.

     6.   Indemnification and Insurance.  The Company shall indemnify Employee
          -----------------------------
with respect to matters relating to his services as an officer and/or director
of the Company or any of its Affiliates to the extent set forth in the Company's
By-laws and in accordance with the terms of any other indemnification which is
generally applicable to executive officers of the Company or any of its
Affiliates that may be provided by the Company or any such Affiliate from time
to time. The foregoing indemnity is contractual and will survive any adverse
amendment to or repeal of the By-laws. The Company will also cover Employee
under a policy of officers' and directors' liability insurance providing
coverage that is comparable to that provided now or hereafter to any other
executive officer or director of the Company or GroupMAC. The provisions of this
Section 6 will survive the termination of Employee's employment for any reason
and the term of this Agreement.

     7.   Change in Control of the Company.
          --------------------------------

     (a)  If a Change of Control (as defined in Exhibit A attached hereto)
occurs and if during the Protected Period (as defined in Exhibit A attached
hereto), Employee's employment is terminated, whether by the Company or by
Employee, then the Company shall promptly pay or otherwise provide to Employee
the benefits set forth below:

          (i)   An amount equal to two times the sum of (A) Employee's Annual
     Base Salary then in effect and (B) Employee's target bonus for the calendar
     year in which such termination occurs (assuming the maximum target bonus
     will be earned for such year), payable in a single lump sum by certified or
     bank cashier's check within five days of such termination; and

          (ii)  An amount equal to the product of (A) the maximum monthly
     premium payment that may be charged to continue coverage for Employee and
     Employee's dependents under the Company's health insurance plan under
     COBRA, multiplied by (B) 24 months.
            ----------

Notwithstanding the foregoing, Employee shall not be entitled to any benefits
under this Section 7 if such termination is (i) due to Employee's death, (ii) by
the Company on account of Employee's Disability as provided in Section 10(d)
below, (iii) by the Company for Cause as provided in Section 10(a) below, or
(iv) by Employee for other than Good Reason (as defined in Exhibit A attached
hereto) as provided in Section 10 below.

     8.   Gross-Up of Parachute Payments.
          ------------------------------

                                       3
<PAGE>

     (a)  To provide Employee with adequate protection in connection with his
ongoing employment with the Company, this Agreement provides Employee with
various benefits in the event of termination of Employee's employment with the
Company during the Protected Period. If Employee's employment is terminated
following a "change of control" of GroupMAC or the Company, within the meaning
of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), a
                                                                       ----
portion of those benefits could be characterized as "excess parachute payments"
within the meaning of Section 280G of the Code. The parties hereto acknowledge
that the protections set forth in this Section 8 are important, and it is agreed
that Employee should not have to bear the burden of any excise tax that might be
levied under Section 4999 of the Code or any similar provision of state or
federal law, in the event that any portion of the benefits payable to Employee
pursuant to this Agreement are treated as an excess parachute payment. The
parties, therefore, have agreed as set forth in this Section 8.

     (b)  Anything in this Agreement to the contrary notwithstanding, if it
shall be determined that any payment or distribution (including income
recognized by Employee upon the early vesting of restricted property or upon the
exercise of options whose exercise date has been accelerated) by GroupMAC or the
Company or any other person to or for the benefit of Employee (whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise, but determined without regard to any additional payments required
under this Section 8) (a "Payment") would be subject to the excise tax imposed
                          -------
by Section 4999 of the Code or any similar provision of state or federal law or
any interest or penalties are incurred by Employee with respect to such excise
tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then the Company
                                             ----------
shall pay an additional payment (a "Gross-Up Payment") in an amount such that
                                    ----------------
after payment by Employee of all taxes (including any interest or penalties
imposed with respect to such taxes), including, without limitation, any income
taxes (and any interest and penalties imposed with respect thereto) and Excise
Tax imposed on the Gross-Up Payment, Employee retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed on the Payments.

     (c)  Subject to the provisions of Section 8(d) below, all determinations
required to be made under this Section 8, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by an
independent public accounting firm with a national reputation selected by
Employee (the "Accounting Firm") that shall provide detailed supporting
               ---------------
calculations both to the Company and to Employee within 15 business days after
the receipt of notice from Employee that there has been a Payment, or such
earlier time as is requested by the Company. In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the change in control of GroupMAC or the Company, Employee shall
appoint another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall
be borne solely by the Company. The Company shall indemnify and hold harmless
Employee, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed on Employee as a result of
such payment of fees and expenses. Any Gross-Up Payment, as determined pursuant
to this Section 8, shall be paid by the Company to Employee within five days of
the receipt of the Accounting

                                       4
<PAGE>

Firm's determination. If the Accounting Firm determines that no Excise Tax is
payable by Employee, it shall furnish Employee with a written opinion that
failure to report the Excise Tax on Employee's applicable federal income tax
return would not result in the imposition of a negligence or similar penalty.
Any determination by the Accounting Firm shall be binding on the Company and
Employee. As a result of uncertainty in the application of Section 4999 of the
Code at the time of the initial determination by the Accounting Firm hereunder,
it is possible that Gross-Up Payments may not have been made by the Company that
should have been made ("Underpayment"), consistent with the calculations
                        ------------
required to be made hereunder. If the Company exhausts its remedies pursuant to
Section 8(d) below and Employee thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of Employee.

     (d)  Employee shall notify the Company in writing of any claim (including
any threatened tax lien related to or based on any such claims) by the Internal
Revenue Service that, if successful, would require the payment by the Company of
the Gross-Up Payment.  Such notification shall be given as soon as practicable
but no later than 10 business days after Employee is informed in writing of such
claim (or threatened lien) and shall apprize the Company of the nature of such
claim and the date on which such claim is requested to be paid. Employee shall
not pay such claim prior to the expiration of the 30-day period following the
date on which Employee gives such notice to the Company (or such shorter period
ending on the date that any payment of taxes with respect to such claim is due
or such tax lien would be imposed). If the Company notifies Employee in writing
prior to the expiration of such period that it desires to contest such claim (or
threatened lien), Employee shall:

          (i)   give the Company any information reasonably requested by the
     Company relating to such claims (or threatened lien);

          (ii)  take such action in connection with contesting such claim (or
     threatened lien) as the Company shall reasonably request in writing from
     time to time, including, without limitation, accepting legal representation
     with respect to such claim by an attorney reasonably selected by the
     Company;

          (iii) cooperate with the Company in good faith in order effectively
     to contest such claim (or threatened lien); and

          (iv)  permit the Company to participate in any proceedings relating to
     such claims (or threatened lien);

provided, however, that the Company shall bear and pay directly all costs and
expenses (including legal fees and expenses, additional interest and penalties)
incurred in connection with such contest and shall indemnify and hold Employee
harmless, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed as a result of such
representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 8(d), the Company shall control all
proceedings taken in

                                       5
<PAGE>

connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct Employee to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and Employee shall prosecute such contest to a
determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as Employee shall determine
(but in no event shall the Company permit or direct Employee to allow a tax lien
to be imposed on Employee's property); provided, further, that if the Company
directs Employee to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to Employee, on an interest-free basis, and
shall indemnify and hold Employee harmless on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided, further, that any extension of the
statute of limitations relating to payment of taxes for the taxable year of
Employee with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. In addition, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder, and Employee shall be entitled to settle or contest,
as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority.

     (e)  If, after the receipt by Employee of an amount advanced by the Company
pursuant to Section 8(d), Employee becomes entitled to receive any refund with
respect to such claim, Employee shall (subject to the Company's complying with
the requirements of Section 8(d) above) promptly pay to the Company the amount
of such refund (together with any interest paid or credited thereon after taxes
applicable thereto). If after the receipt by Employee of an amount advanced by
the Company pursuant to Section 8(d) above, a determination is made that
Employee shall not be entitled to any refund with respect to such claim and the
Company does not notify Employee in writing of its intent to contest such denial
of refund prior to the expiration of 30 days after such determination, then such
advance shall be forgiven and shall not be required to be repaid and the amount
of such advance shall offset, to the extent thereof, the amount of Gross-Up
Payment required to be paid.

     9.   Acceleration of Options.  Upon the occurrence of any of the following
          -----------------------
events at a time while Employee holds outstanding options to purchase GroupMAC
Common Stock, all such options shall be immediately exercisable in full:

          (i)   the acquisition described in clause (i) of the definition of
     Change of Control;

          (ii)  the change in the composition of the Board of Directors
     described in clause (ii) of such definition;

          (iii) the shareholder approval or adoption described in clauses (iii)
     or (iv) of such definition;

                                       6
<PAGE>

          (iv)  the commencement date of any tender offer subject to the terms
     of Section 14(d)(1) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or exchange offer subject to the terms of the Securities
      ------------
     Act of 1933, as amended (the "Securities Act"), or any other offer or
                                   --------------
     series of offers to purchase for cash, or to exchange for securities of a
     person other than the Company or any of its affiliates, GroupMAC Common
     Stock by any "person" or "group" of persons (as such terms are used in Rule
     13d of the Exchange Act) other than an offer or offers by GroupMAC or by
     employee benefit plan(s) sponsored by GroupMAC ("Tender Offer") if such
                                                      ------------
     person or group would hold 30% or more of the then outstanding GroupMAC
     Common Stock after the consummation of the Tender Offer.

     10.  Termination.
          -----------

     (a)  Either the Company or Employee may terminate Employee's employment
hereunder at any time by delivery of written notice by the terminating party of
its election to terminate this Agreement to the other party. Promptly after such
termination of employment, the Company shall pay to Employee an amount equal to
the sum of (i) Employee's earned but unpaid Annual Base Salary through the date
of termination of employment at the rate in effect at the time of such
termination, (ii) vacation pay earned but not taken to the date of such
termination, and (iii) all other amounts previously deferred by Employee or
earned but not paid as of such date under all Company incentive or deferred
compensation plans or programs.

     (b)  If the Company terminates Employee's employment without Cause, then
the Company shall promptly pay to Employee the following amounts in addition to
those set forth in Section 10(a):

          (i)   If such termination occurred during a Protected Period, the
     amounts set forth in Section 7; and

          (ii)  If such termination did not occur during a Protected Period,

                (A)  an amount equal to 12 months' compensation at Employee's
          then current Annual Base Salary, payable semimonthly, and shall
          continue to provide benefits in the kind and amounts provided up to
          the date of termination for a 12 month period including, without
          limitation, continuation of any Company-paid benefits as described in
          Section 5 for Employee and Employee's family;

                (B)  any portion of Employee's bonus for the calendar year prior
          to the calendar year in which such termination of employment occurs
          which has not been paid; and

                (C)  an additional amount equal to a prorated portion of
          Employee's target bonus for the calendar year in which such
          termination occurs, assuming that Employee would have earned the
          maximum target bonus for such year (such prorated portion to be
          determined based upon the number of working days

                                       7
<PAGE>

          Employee is employed by the Company during the calendar year in which
          Employee's employment is terminated divided by the total number of
          working days in such calendar year).

     The amounts described in clauses (B) and (C) above shall be paid promptly
     after the determination of such bonuses, but in any event prior to the
     publication of financial statements of GroupMAC for such year.

     (c)  If Employee terminates Employee's employment for Good Reason during a
Protected Period, then the Company shall promptly pay to Employee, in addition
to the amounts set forth in Section 10(a), the amounts set forth in Section 7.

     (d)  In the event this Agreement is terminated by the Company without Cause
or by Employee with Good Reason, Employee agrees to accept, in full settlement
of any and all claims, losses, damages and other demands that Employee may have
arising out of such termination, as liquidated damages and not as a penalty, the
payments set forth in this Agreement. Employee hereby waives any and all rights
Employee may have to bring any cause of action or proceeding contesting any
termination without Cause or Good Reason; provided, however, that such waiver
shall not be deemed to affect Employee's rights to enforce any other obligations
of the Company. Under no circumstances shall Employee be entitled to any
compensation or confirmation of any benefits under this Agreement for any period
of time following Employee's date of termination if Employee's termination is
for Cause.

     (e)  If at any time during the term of this Agreement, Employee is unable
due to physical or mental disability, to perform effectively Employee's duties
hereunder, the Company shall continue payment of compensation as provided in
Section 4 during the first 12 month period of such disability to the extent not
covered by the Company's disability insurance policies. Upon the expiration of
such 12 month period, the Company, at its sole option, may continue payment of
Employee's salary for such additional periods as the Company elects, or may
terminate this Agreement without any further obligations hereunder. If Employee
should die during the term of this Agreement, Employee's employment and the
Company's obligations hereunder shall terminate as of the end of the month in
which Employee's death occurs.

     (f)  So long as Employee receives a severance as provided in Section 10(b)
above, Employee shall sign any lock-up letters, standstill agreements, or other
similar documentation required by an underwriter in connection with a public
offering of securities by GroupMAC or take other actions reasonably related
thereto as requested by the Board of Directors of GroupMAC; provided, however,
that the period of any such lock-up or standstill agreement shall not exceed the
shorter of (i) 180 days or (ii) the balance of the severance period. Failure to
take any such action shall cause Employee to forfeit any further rights to the
salary continuation payments in Section 10(b)(ii). In addition, in such event
the Company can seek and obtain specific performance of such covenant, including
any injunction requiring execution thereof, and Employee hereby appoints the
then current president of the Company to sign any such documents on his behalf
so long as such documents are prepared on the same basis as other shareholders
generally or as all management shareholders.

                                       8

     11.  No Mitigation Obligation.  The Company acknowledges that it will be
          ------------------------
difficult and may be impossible (i) for Employee to find reasonably comparable
employment following termination of Employee's employment and (ii) to measure
the amount of damages which Employee may suffer as a result of the termination
of Employee's employment.  Accordingly, all amounts paid to Employee under this
Agreement following Employee's termination of employment are acknowledged by the
Company to be reasonable and to be liquidated damages, and Employee will not be
required to mitigate the amount of such payments by seeking other employment or
otherwise, nor will any profits, income, earnings or other benefits from any
source whatsoever (including from other employment) create any mitigation,
offset, reduction or any other obligation on the part of Employee under this
Agreement.

     12.  Covenant Not to Compete.
          -----------------------

     (a)  During Employee's employment with the Company or any of its Affiliates
(as defined in Exhibit A attached hereto) and thereafter during the Restricted
Period (as defined in Exhibit A attached hereto), regardless of the reason for
the termination of Employee's employment, Employee will not engage in or carry
on, directly or indirectly, either for himself or as a member of a partnership
or as a shareholder, investor, owner, officer or director of a company or other
entity, or as an employee, agent, associate or consultant of any person,
partnership, corporation or other entity, any business in any State of the
United States or in any other part of the world that directly competes with any
services or products produced, sold, conducted, developed, or in the process of
development by the Company or its Affiliates on the date of termination of
Employee's employment.

     (b)  Notwithstanding the foregoing, Employee shall be permitted to engage
in the following activities which could otherwise be covered by Section 12(a):

          (i)   the ownership of less than one percent of any class of
     securities of a publicly-held company whose gross assets exceed
     $100,000,000; and

          (ii)  working in the indoor air quality, heating, ventilation and air
     conditioning or plumbing maintenance services industry if such activities
     are not in direct competition with any products or services produced, sold,
     conducted, developed, or in the process of development by the Company or
     its Affiliates on the date of termination of Employee's employment.

     (c)  Employee acknowledges that the limitations set forth herein on his
rights to compete with the Company and its Affiliates are reasonable and
necessary for the protection of the Company and its Affiliates. In this regard,
Employee specifically agrees that the limitations as to period of time and
geographic area, as well as all other restrictions on his activities specified
herein, are reasonable and necessary for the protection of the Company and its
Affiliates. In particular, Employee acknowledges that the parties anticipate
that Employee will be actively seeking markets for the products and services of
the Company and its Affiliates throughout the United States during Employee's
employment with the Company.

                                       9
<PAGE>

     (d)  In the event that there shall be any violation of the covenant not to
compete set forth in this Section 12, then the time limitation thereof shall be
extended for a period of time equal to the period of time during which such
violation continues; and in the event the Company is required to seek relief
from such violation in any court, board of arbitration or other tribunal, then
the covenant shall be extended for a period of time equal to the pendency of
such proceedings, including all appeals.

     (e)  Employee agrees that the remedy at law for any breach by Employee of
this Section 12 will be inadequate and that the Company shall also be entitled
to injunctive relief.

     13.  Confidential Information.  During the term of this Agreement, and for
          ------------------------
five years after Employee's termination of employment, Employee shall not use or
disclose, without the prior written consent of the Company, Confidential
Information (as defined in Exhibit A attached hereto) relating to the Company or
any of its Affiliates, and upon termination of Employee's employment will return
to the Company all written materials in Employee's possession embodying such
Confidential Information. Employee will promptly disclose to the Company all

          (iii) two years after the termination of Employee's employment, if
     Employee is entitled to benefits under Section 10(b)(i).

                             EMPLOYMENT AGREEMENT


     This Employment Agreement (this "Agreement") is effective as of March 1,
                                      ---------
1998, between GroupMAC Management Co., a Delaware corporation (the "Company"),
                                                                    -------
Group Maintenance America Corp., a Texas corporation ("GroupMAC"), and Chester
                                                       --------
J. Jachimiec, a resident of Harris County, Texas ("Employee").
                                                   --------

                             W I T N E S S E T H:

     WHEREAS, Employee and GroupMAC entered into an Employment Agreement dated
as of October 24, 1996 (the "Original Employment Agreement"); and
                             -----------------------------

     WHEREAS, GroupMAC assigned the Original Employment Agreement to the
Company, and Employee became an employee of the Company, effective as of March
1, 1998; and

     WHEREAS, the Company, GroupMAC and Employee desire to amend and restate the
Original Employment Agreement to reflect the effects of the foregoing
assignment, to modify the provisions of the Original Employment Agreement
pertaining to changes of control of GroupMAC, and to make certain other changes;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties hereby amend and restate the Original Employment
Agreement as follows:

     1.   Employment.  The Company hereby agrees to employ Employee and the
          ----------
Employee hereby agrees to work for the Company as its Executive Vice President-
Acquisitions.  Employee's principal office shall be in Houston, Texas.
Employee will report to the Chief Executive Officer of the Company.  Subject to
consultation with the Chief Executive Officer, Employee will have direct
supervisory responsibility and authority for the implementation of the Company's
program to expand its business through acquisitions.   So long as he is employed
by the Company, Employee shall devote his skill, energy and best efforts to the
faithful discharge of his duties as an employee of the Company.  In providing
services hereunder, Employee shall comply with and follow all directives,
policies, standards and regulations from time to time established by the Board
of Directors of the Company.

     2.   Term of Employment.  Employee's employment by the Company pursuant to
          ------------------
this Agreement shall continue in effect for an initial term of three years from
the date of this Agreement, unless terminated in accordance with Section 7, and
shall be extended from year to year thereafter, unless terminated effective as
of the end of the initial term or any one-year extension thereafter by written
notice from the Company to Employee, or by written notice of Employee to the
Company, delivered not less than 90 days prior to the end of the initial term,
or the anniversary of such one-year extension, as applicable.
<PAGE>

     3.   Representations and Warranties.  Employee represents and warrants that
          -------------------------------
he is under no contractual or other restrictions or obligations that will
significantly limit his activities on behalf of the Company or will prohibit or
limit the disclosure or use of by Employee of any information which directly or
indirectly relates to the nature of the Company or the services to be rendered
by Employee under this Agreement.

     4.   Compensation.  Subject to the provisions of Section 10, Employee will
          ------------
be entitled to the compensation and benefits set forth in this Section 4.

     (a)  During 1998, the Company shall pay Employee an Annual Base Salary,
payable semi-monthly, in equal semi-monthly installments at a rate equal to
$140,000 per year. In each subsequent calendar year during the term of this
Agreement, the Company shall pay to Employee an Annual Base Salary equal to the
greater of (i) his salary for the immediately preceding year or (ii) if
determined otherwise by the Board of Directors, an Annual Base Salary determined
by the Board of Directors following its annual salary and performance review.

     (b)  Employee shall be eligible to receive an annual bonus pursuant to the
incentive compensation program in effect from time to time for executive
employees of GroupMAC. The target bonus of Employee under such program shall not
be less than 90% of Employee's annual salary.

     (c)  All payments of salary and other compensation to Employee shall be
made after deduction of any taxes required to be withheld with respect thereto
under applicable federal and state laws.

     5.   Fringe Benefits; Expenses.  (a) Employee shall participate in all
          -------------------------
employee benefit plans sponsored by the Company or GroupMAC for its executive
employees, including but not limited to stock bonus, stock purchase and stock
option plans, sick leave and disability leave, health insurance, dental
insurance and pension and/or profit sharing plans; provided, however, that
except as provided below, the nature, amount and limitations of such plans shall
be determined from time to time by the Board of Directors of the Company.

     (b)  The Company will reimburse Employee for all reasonable business
expenses incurred by Employee in the scope of his employment; provided, however,
that Employee must file expense reports with respect to such expenses in
accordance with the Company's policies as are in effect from time to time.

     (c)  Employee shall be entitled to a minimum of three weeks paid vacation
during each calendar year, increasing to four weeks at January 1, 1999, and to
paid holidays and other paid leave set forth in the Company's policies in effect
from time to time.  Any vacation not used during a calendar year may not be used
during any subsequent period.

     (d)  The Company will pay all license fees, occupation taxes and reasonable
educational costs and expenses necessary to maintain Employee's good standing
under any professional licenses.

                                       2
<PAGE>

     (e)  The Company shall use reasonable efforts to provide (i) life insurance
payable to Employee's designated beneficiary in an amount at least three times
Employee's Annual Base Salary and (ii) disability insurance on behalf of
Employee which, as a goal, shall provide for salary continuation in the event of
permanent disability in an amount not less than 60% of Employee's Annual Base
Salary, it being acknowledged by Employee that GroupMAC's present disability
insurance provides a limit of $5,000 per month.

     6.   Indemnification and Insurance.  The Company shall indemnify Employee
          -----------------------------
with respect to matters relating to his services as an officer and/or director
of the Company or any of its Affiliates to the extent set forth in the Company's
By-laws and in accordance with the terms of any other indemnification which is
generally applicable to executive officers of the Company or any of its
Affiliates that may be provided by the Company or any such Affiliate from time
to time. The foregoing indemnity is contractual and will survive any adverse
amendment to or repeal of the By-laws. The Company will also cover Employee
under a policy of officers' and directors' liability insurance providing
coverage that is comparable to that provided now or hereafter to any other
executive officer or director of the Company or GroupMAC. The provisions of this
Section 6 will survive the termination of Employee's employment for any reason
and the term of this Agreement.

     7.   Change in Control of the Company.
          --------------------------------

     (a)  If a Change of Control (as defined in Exhibit A attached hereto)
occurs and if during the Protected Period (as defined in Exhibit A attached
hereto), Employee's employment is terminated, whether by the Company or by
Employee, then the Company shall promptly pay or otherwise provide to Employee
the benefits set forth below:

          (i)  An amount equal to two times the sum of (A) Employee's Annual
     Base Salary then in effect and (B) Employee's target bonus for the calendar
     year in which such termination occurs (assuming the maximum target bonus
     will be earned for such year), payable in a single lump sum by certified or
     bank cashier's check within five days of such termination; and

          (ii) An amount equal to the product of (A) the maximum monthly premium
     payment that may be charged to continue coverage for Employee and
     Employee's dependents under the Company's health insurance plan under
     COBRA, multiplied by (B) 24 months.
            ----------

Notwithstanding the foregoing, Employee shall not be entitled to any benefits
under this Section 7 if such termination is (i) due to Employee's death, (ii) by
the Company on account of Employee's Disability as provided in Section 10(d)
below, (iii) by the Company for Cause as provided in Section 10(a) below, or
(iv) by Employee for other than Good Reason (as defined in Exhibit A attached
hereto) as provided in Section 10 below.

     8.   Gross-Up of Parachute Payments.
          ------------------------------

                                       3
<PAGE>

     (a)  To provide Employee with adequate protection in connection with his
ongoing employment with the Company, this Agreement provides Employee with
various benefits in the event of termination of Employee's employment with the
Company during the Protected Period. If Employee's employment is terminated
following a "change of control" of GroupMAC or the Company, within the meaning
of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), a
                                                                       ----
portion of those benefits could be characterized as "excess parachute payments"
within the meaning of Section 280G of the Code.  The parties hereto acknowledge
that the protections set forth in this Section 8 are important, and it is agreed
that Employee should not have to bear the burden of any excise tax that might be
levied under Section 4999 of the Code or any similar provision of state or
federal law, in the event that any portion of the benefits payable to Employee
pursuant to this Agreement are treated as an excess parachute payment.  The
parties, therefore, have agreed as set forth in this Section 8.

     (b)  Anything in this Agreement to the contrary notwithstanding, if it
shall be determined that any payment or distribution (including income
recognized by Employee upon the early vesting of restricted property or upon the
exercise of options whose exercise date has been accelerated) by GroupMAC or the
Company or any other person to or for the benefit of Employee (whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise, but determined without regard to any additional payments required
under this Section 8) (a "Payment") would be subject to the excise tax imposed
                          -------
by Section 4999 of the Code or any similar provision of state or federal law or
any interest or penalties are incurred by Employee with respect to such excise
tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then the Company
                                             ----------
shall pay an additional payment (a  "Gross-Up Payment") in an amount such that
                                     ----------------
after payment by Employee of all taxes (including any interest or penalties
imposed with respect to such taxes), including, without limitation, any income
taxes (and any interest and penalties imposed with respect thereto) and Excise
Tax imposed on the Gross-Up Payment, Employee retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed on the Payments.

     (c)  Subject to the provisions of Section 8(d) below, all determinations
required to be made under this Section 8, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by an
independent public accounting firm with a national reputation selected by
Employee (the "Accounting Firm") that shall provide detailed supporting
               ---------------
calculations both to the Company and to Employee within 15 business days after
the receipt of notice from Employee that there has been a Payment, or such
earlier time as is requested by the Company.  In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the change in control of GroupMAC or the Company, Employee shall
appoint another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder).  All fees and expenses of the Accounting Firm shall
be borne solely by the Company.  The Company shall indemnify and hold harmless
Employee, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed on Employee as a result of
such payment of fees and expenses.  Any Gross-Up Payment, as determined pursuant
to this Section 8, shall be paid by the Company to Employee within five days of
the receipt of the Accounting

                                       4
<PAGE>

Firm's determination. If the Accounting Firm determines that no Excise Tax is
payable by Employee, it shall furnish Employee with a written opinion that
failure to report the Excise Tax on Employee's applicable federal income tax
return would not result in the imposition of a negligence or similar penalty.
Any determination by the Accounting Firm shall be binding on the Company and
Employee. As a result of uncertainty in the application of Section 4999 of the
Code at the time of the initial determination by the Accounting Firm hereunder,
it is possible that Gross-Up Payments may not have been made by the Company that
should have been made ("Underpayment"), consistent with the calculations
                        ------------
required to be made hereunder. If the Company exhausts its remedies pursuant to
Section 8(d) below and Employee thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of Employee.

     (d)  Employee shall notify the Company in writing of any claim (including
any threatened tax lien related to or based on any such claims) by the Internal
Revenue Service that, if successful, would require the payment by the Company of
the Gross-Up Payment.  Such notification shall be given as soon as practicable
but no later than 10 business days after Employee is informed in writing of such
claim (or threatened lien) and shall apprize the Company of the nature of such
claim and the date on which such claim is requested to be paid. Employee shall
not pay such claim prior to the expiration of the 30-day period following the
date on which Employee gives such notice to the Company (or such shorter period
ending on the date that any payment of taxes with respect to such claim is due
or such tax lien would be imposed). If the Company notifies Employee in writing
prior to the expiration of such period that it desires to contest such claim (or
threatened lien), Employee shall:

          (i)    give the Company any information reasonably requested by the
     Company relating to such claims (or threatened lien);

          (ii)   take such action in connection with contesting such claim (or
     threatened lien) as the Company shall reasonably request in writing from
     time to time, including, without limitation, accepting legal representation
     with respect to such claim by an attorney reasonably selected by the
     Company;

          (iii)  cooperate with the Company in good faith in order effectively
     to contest such claim (or threatened lien); and

          (iv)   permit the Company to participate in any proceedings relating
     to such claims (or threatened lien);

provided, however, that the Company shall bear and pay directly all costs and
expenses (including legal fees and expenses, additional interest and penalties)
incurred in connection with such contest and shall indemnify and hold Employee
harmless, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed as a result of such
representation and payment of costs and expenses.  Without limitation on the
foregoing provisions of this Section 8(d), the Company shall control all
proceedings taken in

                                       5
<PAGE>

connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct Employee to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and Employee shall prosecute such contest to a
determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as Employee shall determine
(but in no event shall the Company permit or direct Employee to allow a tax lien
to be imposed on Employee's property); provided, further, that if the Company
directs Employee to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to Employee, on an interest-free basis, and
shall indemnify and hold Employee harmless on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided, further, that any extension of the
statute of limitations relating to payment of taxes for the taxable year of
Employee with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. In addition, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder, and Employee shall be entitled to settle or contest,
as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority.

     (e)  If, after the receipt by Employee of an amount advanced by the Company
pursuant to Section 8(d), Employee becomes entitled to receive any refund with
respect to such claim, Employee shall (subject to the Company's complying with
the requirements of Section 8(d) above) promptly pay to the Company the amount
of such refund (together with any interest paid or credited thereon after taxes
applicable thereto).  If after the receipt by Employee of an amount advanced by
the Company pursuant to Section 8(d) above, a determination is made that
Employee shall not be entitled to any refund with respect to such claim and the
Company does not notify Employee in writing of its intent to contest such denial
of refund prior to the expiration of 30 days after such determination, then such
advance shall be forgiven and shall not be required to be repaid and the amount
of such advance shall offset, to the extent thereof, the amount of Gross-Up
Payment required to be paid.

     9.   Acceleration of Options.  Upon the occurrence of any of the following
          -----------------------
events at a time while Employee holds outstanding options to purchase GroupMAC
Common Stock, all such options shall be immediately exercisable in full:

          (i)    the acquisition described in clause (i) of the definition of
     Change of Control;

          (ii)   the change in the composition of the Board of Directors
     described in clause (ii) of such definition;

          (iii)  the shareholder approval or adoption described in clauses (iii)
     or (iv) of such definition;

                                       6
<PAGE>

          (iv)   the commencement date of any tender offer subject to the terms
     of Section 14(d)(1) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or exchange offer subject to the terms of the Securities
      ------------
     Act of 1933, as amended (the "Securities Act"), or any other offer or
                                   --------------
     series of offers to purchase for cash, or to exchange for securities of a
     person other than the Company or any of its affiliates, GroupMAC Common
     Stock by any "person" or "group" of persons (as such terms are used in Rule
     13d of the Exchange Act) other than an offer or offers by GroupMAC or by
     employee benefit plan(s) sponsored by GroupMAC ("Tender Offer") if such
                                                      ------------
     person or group would hold 30% or more of the then outstanding GroupMAC
     Common Stock after the consummation of the Tender Offer.

     10.  Termination.
          -----------

     (a)  Either the Company or Employee may terminate Employee's employment
hereunder at any time by delivery of written notice by the terminating party of
its election to terminate this Agreement to the other party. Promptly after such
termination of employment, the Company shall pay to Employee an amount equal to
the sum of (i) Employee's earned but unpaid Annual Base Salary through the date
of termination of employment at the rate in effect at the time of such
termination, (ii) vacation pay earned but not taken to the date of such
termination, and (iii) all other amounts previously deferred by Employee or
earned but not paid as of such date under all Company incentive or deferred
compensation plans or programs.

     (b)  If the Company terminates Employee's employment without Cause, then
the Company shall promptly pay to Employee the following amounts in addition to
those set forth in Section 10(a):

          (i)  If such termination occurred during a Protected Period, the
     amounts set forth in Section 7; and

          (ii) If such termination did not occur during a Protected Period,

               (A)  an amount equal to 12 months' compensation at Employee's
          then current Annual Base Salary, payable semimonthly, and shall
          continue to provide benefits in the kind and amounts provided up to
          the date of termination for a 12 month period including, without
          limitation, continuation of any Company-paid benefits as described in
          Section 5 for Employee and Employee's family;

               (B) any portion of Employee's bonus for the calendar year prior
          to the calendar year in which such termination of employment occurs
          which has not been paid; and

               (C)  an additional amount equal to a prorated portion of
          Employee's target bonus for the calendar year in which such
          termination occurs, assuming that Employee would have earned the
          maximum target bonus for such year (such prorated portion to be
          determined based upon the number of working days

                                       7
<PAGE>

          Employee is employed by the Company during the calendar year in which
          Employee's employment is terminated divided by the total number of
          working days in such calendar year).

     The amounts described in clauses (B) and (C) above shall be paid promptly
     after the determination of such bonuses, but in any event prior to the
     publication of financial statements of GroupMAC for such year.

     (c)  If Employee terminates Employee's employment for Good Reason during a
Protected Period, then the Company shall promptly pay to Employee, in addition
to the amounts set forth in Section 10(a), the amounts set forth in Section 7.

     (d)  In the event this Agreement is terminated by the Company without Cause
or by Employee with Good Reason, Employee agrees to accept, in full settlement
of any and all claims, losses, damages and other demands that Employee may have
arising out of such termination, as liquidated damages and not as a penalty, the
payments set forth in this Agreement. Employee hereby waives any and all rights
Employee may have to bring any cause of action or proceeding contesting any
termination without Cause or Good Reason; provided, however, that such waiver
shall not be deemed to affect Employee's rights to enforce any other obligations
of the Company. Under no circumstances shall Employee be entitled to any
compensation or confirmation of any benefits under this Agreement for any period
of time following Employee's date of termination if Employee's termination is
for Cause.

     (e)  If at any time during the term of this Agreement, Employee is unable
due to physical or mental disability, to perform effectively Employee's duties
hereunder, the Company shall continue payment of compensation as provided in
Section 4 during the first 12 month period of such disability to the extent not
covered by the Company's disability insurance policies. Upon the expiration of
such 12 month period, the Company, at its sole option, may continue payment of
Employee's salary for such additional periods as the Company elects, or may
terminate this Agreement without any further obligations hereunder. If Employee
should die during the term of this Agreement, Employee's employment and the
Company's obligations hereunder shall terminate as of the end of the month in
which Employee's death occurs.

     (f)  So long as Employee receives a severance as provided in Section 10(b)
above, Employee shall sign any lock-up letters, standstill agreements, or other
similar documentation required by an underwriter in connection with a public
offering of securities by GroupMAC or take other actions reasonably related
thereto as requested by the Board of Directors of GroupMAC; provided, however,
that the period of any such lock-up or standstill agreements shall not exceed
the shorter of (i) 180 days or (ii) the balance of the severance period. Failure
to take any such action shall cause Employee to forfeit any further rights to
the salary continuation payments in Section 10(b)(ii). In addition, in such
event the Company can seek and obtain specific performance of such covenant,
including any injunction requiring execution thereof, and Employee hereby
appoints the then current president of the Company to sign any such documents on
his behalf so long as such documents are prepared on the same basis as other
shareholders generally or as all management shareholders.

                                       8
<PAGE>

     11.  No Mitigation Obligation.  The Company acknowledges that it will be
          ------------------------
difficult and may be impossible (i) for Employee to find reasonably comparable
employment following termination of Employee's employment and (ii) to measure
the amount of damages which Employee may suffer as a result of the termination
of Employee's employment.  Accordingly, all amounts paid to Employee under this
Agreement following Employee's termination of employment are acknowledged by the
Company to be reasonable and to be liquidated damages, and Employee will not be
required to mitigate the amount of such payments by seeking other employment or
otherwise, nor will any profits, income, earnings or other benefits from any
source whatsoever (including from other employment) create any mitigation,
offset, reduction or any other obligation on the part of Employee under this
Agreement.

     12.  Covenant Not to Compete.
          -----------------------

     (a)  During Employee's employment with the Company or any of its Affiliates
(as defined in Exhibit A attached hereto) and thereafter during the Restricted
Period (as defined in Exhibit A attached hereto), regardless of the reason for
the termination of Employee's employment, Employee will not engage in or carry
on, directly or indirectly, either for himself or as a member of a partnership
or as a shareholder, investor, owner, officer or director of a company or other
entity, or as an employee, agent, associate or consultant of any person,
partnership, corporation or other entity, any business in any State of the
United States or in any other part of the world that directly competes with any
services or products produced, sold, conducted, developed, or in the process of
development by the Company or its Affiliates on the date of termination of
Employee's employment.

     (b)  Notwithstanding the foregoing, Employee shall be permitted to engage
in the following activities which could otherwise be covered by Section 12(a):

          (i)  the ownership of less than one percent of any class of securities
     of a publicly-held company whose gross assets exceed $100,000,000; and

          (ii) working in the indoor air quality, heating, ventilation and air

                             EMPLOYMENT AGREEMENT


     This Employment Agreement (this "Agreement") is effective as of March 1,
                                      ---------
1998, between GroupMAC Management Co., a Delaware corporation (the "Company"),
                                                                    -------

                                                       --------
Miller, a resident of Ft. Bend County, Texas ("Employee").
                                               --------

                             W I T N E S S E T H:

     WHEREAS, Employee and GroupMAC entered into an Employment Agreement dated
as of October 24, 1996 (the "Original Employment Agreement"); and
                             -----------------------------

     WHEREAS, GroupMAC assigned the Original Employment Agreement to the
Company, and Employee became an employee of the Company, effective as of March
1, 1998; and

     WHEREAS, the Company, GroupMAC and Employee desire to amend and restate the
Original Employment Agreement to reflect the effects of the foregoing
assignment, to modify the provisions of the Original Employment Agreement
pertaining to changes of control of GroupMAC, and to make certain other changes;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties hereby amend and restate the Original Employment
Agreement as follows:

     1.   Employment. The Company hereby agrees to employ Employee and the
          ----------
Employee hereby agrees to work for the Company as its Executive Vice President
and Chief Financial Officer. Employee's principal office shall be in Houston,
Texas. Employee will report to the Chief Executive Officer of the Company.
Subject to consultation with the Chief Executive Officer, Employee will have
direct supervisory responsibility and authority for the financing, financial
reporting, tax and risk management function of GroupMAC. So long as he is
employed by the Company, Employee shall devote his skill, energy and best
efforts to the faithful discharge of his duties as an employee of the Company.
In providing services hereunder, Employee shall comply with and follow all
directives, policies, standards and regulations from time to time established by
the Board of Directors of the Company.

     2.   Term of Employment. Employee's employment by the Company pursuant to
          ------------------
this Agreement shall continue in effect for an initial term of three years from
the date of this Agreement, unless terminated in accordance with Section 7, and
shall be extended from year to year thereafter, unless terminated effective as
of the end of the initial term or any one-year extension thereafter by written
notice from the Company to Employee, or by written notice of Employee to the
Company, delivered not less than 90 days prior to the end of the initial term,
or the anniversary of such one-year extension, as applicable.
<PAGE>

     3.   Representations and Warranties.  Employee represents and warrants that
          ------------------------------
he is under no contractual or other restrictions or obligations that will
significantly limit his activities on behalf of the Company or will prohibit or
limit the disclosure or use of by Employee of any information which directly or
indirectly relates to the nature of the Company or the services to be rendered
by Employee under this Agreement.

     4.   Compensation. Subject to the provisions of Section 10, Employee will
          ------------
be entitled to the compensation and benefits set forth in this Section 4.

     (a)  During 1998, the Company shall pay Employee an Annual Base Salary,
payable semi-monthly, in equal semi-monthly installments at a rate equal to
$140,000 per year. In each subsequent calendar year during the term of this
Agreement, the Company shall pay to Employee an Annual Base Salary equal to the
greater of (i) his salary for the immediately preceding year or (ii) if
determined otherwise by the Board of Directors, an Annual Base Salary determined
by the Board of Directors following its annual salary and performance review.

     (b)  Employee shall be eligible to receive an annual bonus pursuant to the
incentive compensation program in effect from time to time for executive
employees of GroupMAC. The target bonus of Employee under such program shall not
be less than 90% of Employee's annual salary.

     (c)  All payments of salary and other compensation to Employee shall be
made after deduction of any taxes required to be withheld with respect thereto
under applicable federal and state laws.

     5.   Fringe Benefits; Expenses. (a) Employee shall participate in all
          -------------------------
employee benefit plans sponsored by the Company or GroupMAC for its executive
employees, including but not limited to stock bonus, stock purchase and stock
option plans, sick leave and disability leave, health insurance, dental
insurance and pension and/or profit sharing plans; provided, however, that
except as provided below, the nature, amount and limitations of such plans shall
be determined from time to time by the Board of Directors of the Company.

     (b)  The Company will reimburse Employee for all reasonable business
expenses incurred by Employee in the scope of his employment; provided, however,
that Employee must file expense reports with respect to such expenses in
accordance with the Company's policies as are in effect from time to time.

     (c)  Employee shall be entitled to a minimum of three weeks paid vacation
during each calendar year, increasing to four weeks at January 1, 1999, and to
paid holidays and other paid leave set forth in the Company's policies in effect
from time to time. Any vacation not used during a calendar year may not be used
during any subsequent period.

     (d)  The Company will pay all license fees, occupation taxes and reasonable
educational costs and expenses necessary to maintain Employee's good standing
under any professional licenses.

                                       2
<PAGE>

     (e)  The Company shall use reasonable efforts to provide (i) life insurance
payable to Employee's designated beneficiary in an amount at least three times
Employee's Annual Base Salary and (ii) disability insurance on behalf of
Employee which, as a goal, shall provide for salary continuation in the event of
permanent disability in an amount not less than 60% of Employee's Annual Base
Salary, it being acknowledged by Employee that GroupMAC's present disability
insurance provides a limit of $5,000 per month.

     6.   Indemnification and Insurance. The Company shall indemnify Employee
          -----------------------------
with respect to matters relating to his services as an officer and/or director
of the Company or any of its Affiliates to the extent set forth in the Company's
By-laws and in accordance with the terms of any other indemnification which is
generally applicable to executive officers of the Company or any of its
Affiliates that may be provided by the Company or any such Affiliate from time
to time. The foregoing indemnity is contractual and will survive any adverse
amendment to or repeal of the By-laws. The Company will also cover Employee
under a policy of officers' and directors' liability insurance providing
coverage that is comparable to that provided now or hereafter to any other
executive officer or director of the Company or GroupMAC. The provisions of this
Section 6 will survive the termination of Employee's employment for any reason
and the term of this Agreement.

     7.   Change in Control of the Company.
          --------------------------------

     (a)  If a Change of Control (as defined in Exhibit A attached hereto)
occurs and if during the Protected Period (as defined in Exhibit A attached
hereto), Employee's employment is terminated, whether by the Company or by
Employee, then the Company shall promptly pay or otherwise provide to Employee
the benefits set forth below:

          (i)   An amount equal to two times the sum of (A) Employee's Annual
     Base Salary then in effect and (B) Employee's target bonus for the calendar
     year in which such termination occurs (assuming the maximum target bonus
     will be earned for such year), payable in a single lump sum by certified or
     bank cashier's check within five days of such termination; and

          (ii)  An amount equal to the product of (A) the maximum monthly
     premium payment that may be charged to continue coverage for Employee and
     Employee's dependents under the Company's health insurance plan under
     COBRA, multiplied by (B) 24 months.
            ----------

Notwithstanding the foregoing, Employee shall not be entitled to any benefits
under this Section 7 if such termination is (i) due to Employee's death, (ii) by
the Company on account of Employee's Disability as provided in Section 10(d)
below, (iii) by the Company for Cause as provided in Section 10(a) below, or
(iv) by Employee for other than Good Reason (as defined in Exhibit A attached
hereto) as provided in Section 10 below.

     8.   Gross-Up of Parachute Payments.
          ------------------------------

                                       3
<PAGE>

     (a)  To provide Employee with adequate protection in connection with his
ongoing employment with the Company, this Agreement provides Employee with
various benefits in the event of termination of Employee's employment with the
Company during the Protected Period. If Employee's employment is terminated
following a "change of control" of GroupMAC or the Company, within the meaning
of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), a
                                                                       ----
portion of those benefits could be characterized as "excess parachute payments"
within the meaning of Section 280G of the Code. The parties hereto acknowledge
that the protections set forth in this Section 8 are important, and it is agreed
that Employee should not have to bear the burden of any excise tax that might be
levied under Section 4999 of the Code or any similar provision of state or
federal law, in the event that any portion of the benefits payable to Employee
pursuant to this Agreement are treated as an excess parachute payment. The
parties, therefore, have agreed as set forth in this Section 8.

     (b)  Anything in this Agreement to the contrary notwithstanding, if it
shall be determined that any payment or distribution (including income
recognized by Employee upon the early vesting of restricted property or upon the
exercise of options whose exercise date has been accelerated) by GroupMAC or the
Company or any other person to or for the benefit of Employee (whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise, but determined without regard to any additional payments required
under this Section 8) (a "Payment") would be subject to the excise tax imposed
                          -------
by Section 4999 of the Code or any similar provision of state or federal law or
any interest or penalties are incurred by Employee with respect to such excise
tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then the Company
                                             ----------
shall pay an additional payment (a "Gross-Up Payment") in an amount such that
                                    ----------------
after payment by Employee of all taxes (including any interest or penalties
imposed with respect to such taxes), including, without limitation, any income
taxes (and any interest and penalties imposed with respect thereto) and Excise
Tax imposed on the Gross-Up Payment, Employee retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed on the Payments.

     (c)  Subject to the provisions of Section 8(d) below, all determinations
required to be made under this Section 8, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by an
independent public accounting firm with a national reputation selected by
Employee (the "Accounting Firm") that shall provide detailed supporting
               ---------------
calculations both to the Company and to Employee within 15 business days after
the receipt of notice from Employee that there has been a Payment, or such
earlier time as is requested by the Company. In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the change in control of GroupMAC or the Company, Employee shall
appoint another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall
be borne solely by the Company. The Company shall indemnify and hold harmless
Employee, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed on Employee as a result of
such payment of fees and expenses. Any Gross-Up Payment, as determined pursuant
to this Section 8, shall be paid by the Company to Employee within five days of
the receipt of the Accounting

                                       4
<PAGE>

Firm's determination. If the Accounting Firm determines that no Excise Tax is
payable by Employee, it shall furnish Employee with a written opinion that
failure to report the Excise Tax on Employee's applicable federal income tax
return would not result in the imposition of a negligence or similar penalty.
Any determination by the Accounting Firm shall be binding on the Company and
Employee. As a result of uncertainty in the application of Section 4999 of the
Code at the time of the initial determination by the Accounting Firm hereunder,
it is possible that Gross-Up Payments may not have been made by the Company that
should have been made ("Underpayment"), consistent with the calculations
                        ------------
required to be made hereunder. If the Company exhausts its remedies pursuant to
Section 8(d) below and Employee thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of Employee.

     (d)  Employee shall notify the Company in writing of any claim (including
any threatened tax lien related to or based on any such claims) by the Internal
Revenue Service that, if successful, would require the payment by the Company of
the Gross-Up Payment. Such notification shall be given as soon as practicable
but no later than 10 business days after Employee is informed in writing of such
claim (or threatened lien) and shall apprize the Company of the nature of such
claim and the date on which such claim is requested to be paid. Employee shall
not pay such claim prior to the expiration of the 30-day period following the
date on which Employee gives such notice to the Company (or such shorter period
ending on the date that any payment of taxes with respect to such claim is due
or such tax lien would be imposed). If the Company notifies Employee in writing
prior to the expiration of such period that it desires to contest such claim (or
threatened lien), Employee shall:

          (i)   give the Company any information reasonably requested by the
     Company relating to such claims (or threatened lien);

          (ii)  take such action in connection with contesting such claim (or
     threatened lien) as the Company shall reasonably request in writing from
     time to time, including, without limitation, accepting legal representation
     with respect to such claim by an attorney reasonably selected by the
     Company;

          (iii) cooperate with the Company in good faith in order effectively to
     contest such claim (or threatened lien); and

          (iv)  permit the Company to participate in any proceedings relating to
     such claims (or threatened lien);

provided, however, that the Company shall bear and pay directly all costs and
expenses (including legal fees and expenses, additional interest and penalties)
incurred in connection with such contest and shall indemnify and hold Employee
harmless, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed as a result of such
representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 8(d), the Company shall control all
proceedings taken in

                                       5
<PAGE>

connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct Employee to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and Employee shall prosecute such contest to a
determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as Employee shall determine
(but in no event shall the Company permit or direct Employee to allow a tax lien
to be imposed on Employee's property); provided, further, that if the Company
directs Employee to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to Employee, on an interest-free basis, and
shall indemnify and hold Employee harmless on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided, further, that any extension of the
statute of limitations relating to payment of taxes for the taxable year of
Employee with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. In addition, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder, and Employee shall be entitled to settle or contest,
as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority.

     (e)  If, after the receipt by Employee of an amount advanced by the Company
pursuant to Section 8(d), Employee becomes entitled to receive any refund with
respect to such claim, Employee shall (subject to the Company's complying with
the requirements of Section 8(d) above) promptly pay to the Company the amount
of such refund (together with any interest paid or credited thereon after taxes
applicable thereto). If after the receipt by Employee of an amount advanced by
the Company pursuant to Section 8(d) above, a determination is made that
Employee shall not be entitled to any refund with respect to such claim and the
Company does not notify Employee in writing of its intent to contest such denial
of refund prior to the expiration of 30 days after such determination, then such
advance shall be forgiven and shall not be required to be repaid and the amount
of such advance shall offset, to the extent thereof, the amount of Gross-Up
Payment required to be paid.

     9.   Acceleration of Options. Upon the occurrence of any of the following
          -----------------------
events at a time while Employee holds outstanding options to purchase GroupMAC
Common Stock, all such options shall be immediately exercisable in full:

          (i)   the acquisition described in clause (i) of the definition of
     Change of Control;

          (ii)  the change in the composition of the Board of Directors
     described in clause (ii) of such definition;

          (iii) the shareholder approval or adoption described in clauses (iii)
     or (iv) of such definition;

                                       6
<PAGE>

          (iv)  the commencement date of any tender offer subject to the terms
     of Section 14(d)(1) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or exchange offer subject to the terms of the Securities
      ------------
     Act of 1933, as amended (the "Securities Act"), or any other offer or
                                   --------------
     series of offers to purchase for cash, or to exchange for securities of a
     person other than the Company or any of its affiliates, GroupMAC Common
     Stock by any "person" or "group" of persons (as such terms are used in Rule
     13d of the Exchange Act) other than an offer or offers by GroupMAC or by
     employee benefit plan(s) sponsored by GroupMAC ("Tender Offer") if such
                                                      ------------
     person or group would hold 30% or more of the then outstanding GroupMAC
     Common Stock after the consummation of the Tender Offer.

     10.  Termination.
          -----------

     (a)  Either the Company or Employee may terminate Employee's employment
hereunder at any time by delivery of written notice by the terminating party of
its election to terminate this Agreement to the other party. Promptly after such
termination of employment, the Company shall pay to Employee an amount equal to
the sum of (i) Employee's earned but unpaid Annual Base Salary through the date
of termination of employment at the rate in effect at the time of such
termination, (ii) vacation pay earned but not taken to the date of such
termination, and (iii) all other amounts previously deferred by Employee or
earned but not paid as of such date under all Company incentive or deferred
compensation plans or programs.

     (b)  If the Company terminates Employee's employment without Cause, then
the Company shall promptly pay to Employee the following amounts in addition to
those set forth in Section 10(a):

          (i)   If such termination occurred during a Protected Period, the
     amounts set forth in Section 7; and

          (ii)  If such termination did not occur during a Protected Period,

                (A)  an amount equal to 12 months' compensation at Employee's
          then current Annual Base Salary, payable semimonthly, and shall
          continue to provide benefits in the kind and amounts provided up to
          the date of termination for a 12 month period including, without
          limitation, continuation of any Company-paid benefits as described in
          Section 5 for Employee and Employee's family;

                (B)  any portion of Employee's bonus for the calendar year prior
          to the calendar year in which such termination of employment occurs
          which has not been paid; and

                (C)  an additional amount equal to a prorated portion of
          Employee's target bonus for the calendar year in which such
          termination occurs, assuming that Employee would have earned the
          maximum target bonus for such year (such prorated portion to be
          determined based upon the number of working days

                                       7
<PAGE>

          Employee is employed by the Company during the calendar year in which
          Employee's employment is terminated divided by the total number of
          working days in such calendar year).

     The amounts described in clauses (B) and (C) above shall be paid promptly
     after the determination of such bonuses, but in any event prior to the
     publication of financial statements of GroupMAC for such year.

     (c)  If Employee terminates Employee's employment for Good Reason during a
Protected Period, then the Company shall promptly pay to Employee, in addition
to the amounts set forth in Section 10(a), the amounts set forth in Section 7.

     (d)  In the event this Agreement is terminated by the Company without Cause
or by Employee with Good Reason, Employee agrees to accept, in full settlement
of any and all claims, losses, damages and other demands that Employee may have
arising out of such termination, as liquidated damages and not as a penalty, the
payments set forth in this Agreement. Employee hereby waives any and all rights
Employee may have to bring any cause of action or proceeding contesting any
termination without Cause or Good Reason; provided, however, that such waiver
shall not be deemed to affect Employee's rights to enforce any other obligations
of the Company. Under no circumstances shall Employee be entitled to any
compensation or confirmation of any benefits under this Agreement for any period
of time following Employee's date of termination if Employee's termination is
for Cause.

     (e)  If at any time during the term of this Agreement, Employee is unable
due to physical or mental disability, to perform effectively Employee's duties
hereunder, the Company shall continue payment of compensation as provided in
Section 4 during the first 12 month period of such disability to the extent not
covered by the Company's disability insurance policies. Upon the expiration of
such 12 month period, the Company, at its sole option, may continue payment of
Employee's salary for such additional periods as the Company elects, or may
terminate this Agreement without any further obligations hereunder. If Employee
should die during the term of this Agreement, Employee's employment and the
Company's obligations hereunder shall terminate as of the end of the month in
which Employee's death occurs.

     (f)  So long as Employee receives a severance as provided in Section 10(b)
above, Employee shall sign any lock-up letters, standstill agreements, or other
similar documentation required by an underwriter in connection with a public
offering of securities by GroupMAC or take other actions reasonably related
thereto as requested by the Board of Directors of GroupMAC; provided, however,
that the period of any such lock-up or standstill agreements shall not exceed
the shorter of (i) 180 days or (ii) the balance of the severance period. Failure
to take any such action shall cause Employee to forfeit any further rights to
the salary continuation payments in Section 10(b)(ii). In addition, in such
event the Company can seek and obtain specific performance of such covenant,
including any injunction requiring execution thereof, and Employee hereby
appoints the then current president of the Company to sign any such documents on
his behalf so long as such documents are prepared on the same basis as other
shareholders generally or as all management shareholders.

                                       8
<PAGE>

     11.  No Mitigation Obligation. The Company acknowledges that it will be
          ------------------------
difficult and may be impossible (i) for Employee to find reasonably comparable
employment following termination of Employee's employment and (ii) to measure

     12.  Covenant Not to Compete.
          -----------------------

     (a)  During Employee's employment with the Company or any of its Affiliates
(as defined in Exhibit A attached hereto) and thereafter during the Restricted
Period (as defined in Exhibit A attached hereto), regardless of the reason for
the termination of Employee's employment, Employee will not engage in or carry
on, directly or indirectly, either for himself or as a member of a partnership
or as a shareholder, investor, owner, officer or director of a company or other
entity, or as an employee, agent, associate or consultant of any person,
partnership, corporation or other entity, any business in any State of the
United States or in any other part of the world that directly competes with any
services or products produced, sold, conducted, developed, or in the process of
development by the Company or its Affiliates on the date of termination of
Employee's employment.

     (b)  Notwithstanding the foregoing, Employee shall be permitted to engage
in the following activities which could otherwise be covered by Section 12(a):

          (i)   the ownership of less than one percent of any class of
     securities of a publicly-held company whose gross assets exceed
     $100,000,000; and

          (ii)  working in the indoor air quality, heating, ventilation and air
     conditioning or plumbing maintenance services industry if such activities
     are not in direct competition with any products or services produced, sold,
     conducted, developed, or in the process of development by the Company or
     its Affiliates on the date of termination of Employee's employment.

     (c)  Employee acknowledges that the limitations set forth herein on his
rights to compete with the Company and its Affiliates are reasonable and
necessary for the protection of the Company and its Affiliates. In this regard,
Employee specifically agrees that the limitations as to period of time and
geographic area, as well as all other restrictions on his activities specified
herein, are reasonable and necessary for the protection of the Company and its
Affiliates. In particular, Employee acknowledges that the parties anticipate
that Employee will be actively seeking markets for the products and services of
the Company and its Affiliates throughout the United States during Employee's
employment with the Company.

     (d)  In the event that there shall be any violation of the covenant not to
compete set forth in this Section 12, then the time limitation thereof shall be
extended for a period of time equal to the period of time during which such
violation continues; and in the event the Company is required to seek relief
from such violation in any court, board of arbitration or other tribunal, then
the covenant shall be extended for a period of time equal to the pendency of
such proceedings, including all appeals.

     (e)  Employee agrees that the remedy at law for any breach by Employee of
this Section 12 will be inadequate and that the Company shall also be entitled
to injunctive relief.

     13.  Confidential Information. During the term of this Agreement, and for
          ------------------------

any of its Affiliates, and upon termination of Employee's employment will return
to the Company all written materials in Employee's possession embodying such
Confidential Information. Employee will promptly disclose to the Company all
Confidential Information, as well as any business opportunity which comes to
Employee's attention during the term of Employee's employment with the Company.
Employee will not take advantage of or divert any business opportunity for the
benefit of Employee or any other Person (as defined in Exhibit A attached
hereto) without the prior written consent of the Company. Employee agrees that
the remedy at law for any breach by him of this Section 13 will be inadequate

the actual or anticipated operations of the Company or any of its Affiliates,
Employee hereby agrees that all patents, trademarks, copyrights, trade secrets,

patentable, and any product, drawing, design, recording, writing, literary work

          ----------------------
supplemented, and any obligation hereunder may be waived, only by a written
instrument executed by the parties hereto. The waiver by either party of a

exists hereunder, reborrowed, at the option of the Company in accordance with
the provisions hereof, and (iv) shall, in the aggregate at any time outstanding,
together with the Letter of Credit Liabilities, not exceed the Total Revolving
Loan Commitment. There shall be no further Advances after the Revolving Loan
Maturity Date. Notwithstanding anything to the contrary contained in this
Agreement, the Company may from time to time request, and Bank of America (or
any successor Bank acting as swingline lender, approved by the Company and the
Administrative Agent, the "Swingline Lender") may at its discretion from time to
time advance (but shall in no event be obligated to advance), Revolving Loans
which are to be funded solely by the Swingline Lender (the "Swingline
Advances"); provided however, that (i) the aggregate principal amount of the
Swingline Advances outstanding at any time shall not exceed $30,000,000 and the
aggregate principal amount of the Outstanding Revolving Credit at any time
(inclusive of the Swingline Advances) shall not exceed the Total Revolving Loan
Commitment, (ii) all Swingline Advances shall bear interest at the Swingline
Lender's cost of funds (as determined by the Swingline Lender in good faith)

Swingline Lender to the Administrative Agent and the other Banks at any time and
from time to time (including, without limitation, at any time following the
occurrence of a Default or an Event of Default) and, in any event, without
notice on the Business Day immediately preceding the Revolving Loan Maturity
Date, each Bank (including, without limitation, the Swingline Lender) severally
agrees, as provided in the first sentence of this Section 2.01(a), and
notwithstanding anything to the contrary contained in this Agreement, any
Default or Event of Default or the inability or failure of the Company or any of
its Subsidiaries to satisfy any condition precedent to funding any of the
Revolving Loans contained in Article IV (which conditions precedent shall not
apply to this sentence), to make a Revolving Loan, in the form of an Alternate
Base Rate Advance, in an amount equal to its Revolving Loan Commitment
Percentage of the aggregate principal amount of the Swingline Advances then
outstanding, and the proceeds of such Revolving Loans shall be promptly paid by
the Administrative Agent to the Swingline Lender and applied as a repayment of
the aggregate principal amount of the Swingline Advances then outstanding.

immediately available funds at the Payment Office. At such time, the
Administrative Agent shall credit the amounts so received to the general deposit

available funds.

     Unless the Administrative Agent shall have been notified by any Bank prior
to disbursement of the Advance by the Administrative Agent that such Bank does
not intend to make available to the Administrative Agent such Bank's portion of
the Advance to be made on such date, the Administrative Agent may assume that
such Bank has made such amount available to the Administrative Agent on such
Advance Date and the Administrative Agent may, in reliance upon such assumption,
make available to the Company a corresponding amount. If such corresponding
amount is not in fact made available to the Administrative Agent by such Bank
and the Administrative Agent has made available same to the Company, the
Administrative Agent shall be entitled to recover such corresponding amount on
demand from such Bank. If such Bank does not pay such corresponding amount
forthwith upon the Administrative Agent's demand therefor, the Administrative
Agent shall promptly notify the Company, and the Company shall pay such
corresponding amount to the Administrative Agent within two (2) Business Days

of its intention to continue such Advance as an Advance of the same Type. Each
such conversion shall be effected by the Company giving the Administrative Agent

shall have the right to voluntarily prepay the Loans in whole or in part at any

Advance to maturity of said Loan (whether by acceleration or otherwise) at a
rate per annum which shall at all times be equal to the lesser of (i) the
Highest Lawful Rate and (ii) the Alternate Base Rate in effect from time to time
plus the applicable Margin for Alternate Base Rate Advances applicable to the
Loans in question, which applicable Margin shall be adjusted on the first day of
each Margin Period. If the Alternate Base Rate is based on the Prime Rate,
interest shall be computed on the basis of the actual number of days elapsed

is based on the Federal Funds Effective Rate, interest shall be computed on the
basis of the actual number of days elapsed over a year of 360 days.

applicable Eurodollar Rate for such Interest Period plus the applicable Margin
for Eurodollar Rate Advances applicable to the Loans in question. The applicable
Eurodollar Rate shall be fixed for each Interest Period and shall not change
during said Interest Period nor shall the applicable Margin, which is added to
said Eurodollar Rate to determine the total interest payable to the Banks, be
adjusted until the first day of each Interest Period that begins after the
effective date of the new Margin Period.

     (c)  Subject to Section 11.08, overdue principal and, to the extent
                     -------------
permitted by law, overdue interest in respect of any Advance and all other
overdue amounts owing hereunder shall bear interest for each day that such
amounts are overdue at a rate per annum equal to the Default Rate.

such Advance to but excluding the date of any repayment thereof and shall be
payable in arrears (i) in respect of Eurodollar Rate Advances (A) on the last
day of the Interest Period applicable thereto and on each Designated Payment
Date during any Interest Period in excess of three (3) months and (B) on the

Interest Period, shall notify the Company thereof. Each such determination
shall, absent manifest error, be final and conclusive and binding on all parties
hereto. In addition, prior to the due date for the payment of interest on any
Advances set forth in the immediately preceding paragraph, the Administrative
Agent shall notify the Company of the amount of interest due by the Company on
all outstanding Advances on the applicable due date, but any failure of the
Administrative Agent to so notify the Company shall not reduce the Company's
liability for the amount owed.

     (f)  So long as any Bank shall be required under regulations of the Board
to maintain reserves with respect to liabilities or assets consisting of or
including Eurocurrency Liabilities and, as a result, the cost to such Bank is
increased above the level it would be but for such requirement, then such Bank
may require the Company to pay to the Administrative Agent, for the account of
such Bank, additional interest on the unpaid principal amount of each such
Eurodollar Rate Advance, from the date of such Advance until such principal
amount is paid in full, at an interest rate per annum equal at all times during
the Interest Period for such Advance to the lesser of (i) the Highest Lawful
Rate and (ii) the remainder obtained by subtracting (A) the Eurodollar Rate for
such Interest Period from (B) the rate obtained by dividing such Eurodollar Rate
referred to in clause (A) above by that percentage equal to 100% minus the
Reserve Percentage of such Bank for such Interest Period. Such additional
interest shall be determined by such Bank as incurred and shall be payable upon
written demand therefor by the Bank to the Company within 180 days of the
incurrence thereof. Each determination by such Bank of additional interest due
under this Section shall be conclusive and binding for all purposes in the
absence of manifest error if such determination is made on a reasonable basis.

     Section 2.11  Interest Periods.
                   ----------------

     (a)  At the time the Company gives any Notice of Advance or Notice of
Conversion or provides notice of its intent to continue a loan as the same Type
in respect of the making of, or conversion into, a Eurodollar Rate Advance, the
Company shall have the right to elect, by giving the Administrative Agent on the
dates and at the times specified in Section 2.03 or Section 2.05, as the case
                                    ------------    ------------
may be, notice of the interest period (each an "Interest Period") applicable to
                                                ---------------
such Eurodollar Rate Advance, which Interest Period shall be a one, two, three,
six, nine or twelve month period; provided, that:
                                  --------

          (i)   the initial Interest Period for any Eurodollar Rate Advance
          shall commence on the date of such Eurodollar Rate Advance (including
          the date of any conversion thereto or continuance thereof pursuant to
          Section 2.05); each Interest Period occurring thereafter in respect of
          ------------
          such Eurodollar Rate Advance shall commence on the expiration date of
          the immediately preceding Interest Period;

          (ii)  if any Interest Period relating to a Eurodollar Rate Advance
          begins on a day for which there is no numerically corresponding day in
          the calendar month at the end of such Interest Period, such Interest
          Period shall end on the last Business Day of such calendar month;

          (iii) if any Interest Period would otherwise expire on a day which is
          not a Business Day, such Interest Period shall expire on the next
          succeeding Business Day, provided, that if there are no more Business
                                   --------
          Days in that month, the Interest Period shall expire on the preceding
          Business Day;

          (iv)  no Interest Period for Advances shall extend beyond the
          applicable Maturity Date; and

          (v)   the Company shall be entitled to have a maximum of fifteen (15)
          separate Eurodollar Rate Advances hereunder for all Loans
                outstanding at any one time.

     (b) If, upon the expiration of any Interest Period applicable to a
Eurodollar Rate Advance, the Company has failed to elect a new Interest Period
to be applicable to such Advance as provided above, the Company shall be deemed
to have elected to convert such Advance into an Alternate Base Rate Advance
effective as of the expiration date of such current Interest Period.

     Section 2.12 Interest Rate Not Ascertainable. In the event that the
                  -------------------------------
Administrative Agent shall determine (which determination shall, absent manifest
error, be final, conclusive and binding upon all parties) that on any date for
determining the Eurodollar Rate for any Interest Period, by reason of any
changes arising after the date of this Agreement affecting the Eurodollar
interbank market adequate and fair means do not exist for ascertaining the
applicable interest rate on the basis provided for in the definition of
Eurodollar Rate, then, and in any such event, the Administrative Agent shall
forthwith give notice to the Company and to the Banks of such determination.
Until the Administrative Agent notifies the Company that the circumstances
giving rise to the suspension

                                      33
<PAGE>

described herein no longer exist, the obligations of the Banks to make
Eurodollar Rate Advances shall be suspended.

     Section 2.13  Legality.
                   --------

     (a)  Notwithstanding anything to the contrary herein contained, if any law
or regulation or the interpretation thereof by any governmental authority
charged with the administration or interpretation thereof makes it unlawful for
any Bank or its Eurodollar Lending Office to make or maintain any Eurodollar
Rate Advance or to give effect to its obligations as contemplated hereby, then,
by prompt written notice to the Company, such Bank may:

          (i)  declare that Eurodollar Rate Advances will not thereafter be made
          by such Bank hereunder, whereupon the right of the Company to receive
          Eurodollar Rate Advances from such Bank hereunder shall be suspended
          until such declaration is subsequently withdrawn, provided, such
                                                            --------
          request for a Eurodollar Rate Advance shall be automatically converted
          (as to such Bank) into a request for an Alternate Base Rate Advance
          and the affected Bank or Banks shall respond thereto as provided
          herein; and

          (ii) require that all outstanding Eurodollar Rate Advances made by
          such Bank be converted to Alternate Base Rate Advances, in which event
          (A) all such Eurodollar Rate Advances shall be automatically converted
          to Alternate Base Rate Advances as of the effective date of such
          notice as provided in paragraph (b) below if required by applicable
          law or regulation, or if not so required, at the end of the current
          Interest Period and (B) all payments and prepayments of principal
          which would otherwise have been applied to repay the converted
          Eurodollar Rate Advances shall instead be applied to repay the
          Alternate Base Rate Advances resulting from the conversion of such
          Eurodollar Rate Advances.

     (b) For purposes of this Section, a notice to the Company by a Bank,
pursuant to paragraph (a) above shall be effective on the date of receipt
thereof by the Company.

     Section 2.14  Change in Law.
                   -------------

     (a)  If any Change in Law

          (i)  shall change the basis of taxation of payments to such Bank of
          the principal of or interest on any Eurodollar Rate Advance made by
          such Bank or any other fees or amounts payable hereunder with respect
          to Eurodollar Rate Advances (other than Excluded Taxes),

          (ii) shall impose, modify or deem applicable any reserve, special
          deposit or similar requirement with respect to Eurodollar Rate
          Advances against assets of, deposits with or for the account of, or
          credit extended by, such Bank (without duplication of any amounts paid
          pursuant to Section 2.10(f)), or
                      ---------------

                                       34
<PAGE>

          (iii) shall impose on such Bank any other condition affecting this
          Agreement with respect to Eurodollar Rate Advances or any Eurodollar
          Rate Advance made by such Bank,

and the result of any of the foregoing clauses (i), (ii) or (iii) shall be to
increase the cost to such Bank of maintaining its Commitment or of making or
maintaining any Eurodollar Rate Advance or to reduce the amount of any sum
received or receivable by such Bank hereunder (whether of principal, interest or
otherwise) in respect thereof by an amount deemed in good faith by such Bank to
be material, then the Company shall pay to such Bank such additional amount as
will compensate it for such increase or reduction within ten (10) days after
notice thereof pursuant to Section 2.14(c).
                           ---------------

     (b)  If any Bank shall have determined in good faith that any Change in Law
has or would have the effect of reducing the rate of return on the capital of
such Bank as a consequence of, or with reference to, such Bank's obligations to
lend hereunder to a level below that which it could have achieved but for such
Change in Law by an amount deemed by such Bank to be material, then, from time
to time, the Company shall pay to the Administrative Agent for the benefit of
such Bank such additional amount as will reasonably compensate it for such
reduction within ten (10) days after notice thereof pursuant to Section 2.14(c).
                                                                ---------------

     (c)  Each Bank will notify the Company through the Administrative Agent of
any event occurring after the date of this Agreement which will entitle it to
compensation pursuant to this Section, as promptly as practicable after it
becomes aware thereof and determines to request compensation and in any case
within 120 days after becoming aware thereof. A certificate setting forth in
reasonable detail the amount necessary to compensate the Bank in question as
specified in paragraph (a) or (b) above, as the case may be, and the calculation
of such amount shall be delivered to the Company and shall be conclusive absent
manifest error if such determination is made on a reasonable basis. The Company
shall pay to the Administrative Agent for the account of such Bank the amount
shown as due on any such certificate within ten (10) days after its receipt of
the same. The failure on the part of any Bank to demand increased compensation
with respect to any Interest Period shall not constitute a waiver of the right
to demand compensation with respect to subsequent Interest Periods within the
120 day time limit set forth above. Each Bank agrees, to the extent it may
lawfully do so without incurring additional costs, to use its best efforts to
minimize costs arising under this section by designating another lending office
for the Loans affected, provided no Bank shall be required to do so.
                        --------
     (d)  Any notice given pursuant to this Section 2.14 shall be deemed to
                                            ------------
contain a representation by the Bank issuing such notice that the increased
costs and charges are common to substantially all of the loan customers of such
Bank and are not unique to the Company.

     Section 2.15  Eurodollar Advance Prepayment and Default Penalties. Subject
                   ---------------------------------------------------
to Section 11.08, the Company shall indemnify each Bank against any loss or
   -------------
expense (excluding loss of anticipated profits) which it may sustain or incur as
a consequence of (a) an Advance of, or a conversion from or into, Eurodollar
Rate Advances that does not occur on the date specified therefor in a Notice of
Advance or Notice of Conversion, (b) any payment, prepayment or conversion of a
Eurodollar Rate Advance required by any other provision of this Agreement or
otherwise made on

                                       35
<PAGE>

a date other than the last day of the applicable Interest Period (including any
thereof arising in connection with syndication of the Commitments within six (6)
months after the Effective Date), or (c) any default in the payment or
prepayment of the principal amount of any Eurodollar Rate Advance or any part
thereof or interest accrued thereon, as and when due and payable (at the due
date thereof, by notice of prepayment or otherwise). Such loss or expense shall
include an amount equal to the excess determined by each Bank of (i) its cost of
obtaining the funds for the Advance being paid, prepaid or converted or not
borrowed (based on the Eurodollar Rate) for the period from the date of such
payment, prepayment or conversion or failure to borrow to the last day of the
Interest Period for such Advance (or, in the case of a failure to borrow, the
Interest Period for the Advance which would have commenced on the date of such
failure to borrow) over (ii) the amount of interest (as determined by each
                   ----
Bank) that would be realized in reemploying the funds so paid, prepaid or
converted or not borrowed for such period or Interest Period, as the case may
be. The Administrative Agent, on behalf of the Banks, will notify the Company of
any loss or expense which will entitle the Banks to compensation pursuant to
this Section, as promptly as possible after it becomes aware thereof, but
failure to so notify shall not affect the Company's liability therefor. A
certificate of any Bank setting forth any amount which it is entitled to receive
pursuant to this Section shall be delivered to the Company and shall be
conclusive absent manifest error if such determination is made on a reasonable
basis. The Company shall pay to the Administrative Agent for the account of the
Banks the amount shown as due on any certificate within ten (10) days after its
receipt of the same. Without prejudice to the survival of any other obligations
of the Company hereunder, the obligations of the Company under this Section
shall survive the termination of this Agreement and the assignment of any of the
Notes.

     Section 2.16  Additional Costs, Taxes or Similar Requirements.
                   -----------------------------------------------

     (a)  General.  Any and all payments by the Company to or for the account of
any Bank or the Administrative Agent hereunder or under any other Loan Document

future Taxes.  If the Company shall be required by Law to deduct any Taxes from
or in respect of any sum payable under this Agreement or any other Loan Document
to any Bank or the Administrative Agent, (i) the sum payable shall be increased
as necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.16) such Bank or the
Administrative Agent receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Company shall make such deductions,
(iii) the Company shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable Law, and (iv) the
Company shall furnish to the Administrative Agent, at its address listed in
Section 11.02, the original or a certified copy of a receipt evidencing payment
- -------------
thereof.

     (b)  Stamp and Documentary Taxes. In addition, to the extent permitted by
applicable Law, the Company agrees to pay any and all present or future stamp or
documentary taxes and any other excise or property taxes or charges or similar
levies which arise from any payment made under this Agreement or any other Loan
Document or from the execution or delivery of, or otherwise with respect to,
this Agreement or any other Loan Document (hereinafter referred to as "Other
Taxes").

                                       36
<PAGE>

     (c)  Indemnification for Taxes. The Company agrees to indemnify each Bank
and the Administrative Agent for the full amount of Taxes and Other Taxes which
the Company is obligated to pay under this Section 2.16 (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 2.16) paid by such Bank or the Administrative
Agent (as the case may be) and any liability (including penalties, interest, and
expenses except any thereof arising from such Bank's willful misconduct or gross
negligence) arising therefrom or with respect thereto.

     (d)  If the Administrative Agent or a Bank (or transferee) receives a
refund (as determined in its sole discretion) of any Taxes or Other Taxes in or
with respect to the taxable year in which it has been indemnified by the
Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section 2.16, it shall pay over such refund to the Borrower
(but only to the extent of indemnity payments made, or additional amounts paid,
by the Borrower under this Section 2.16 with respect to the Taxes or Other Taxes
giving rise of such refund), net of all out-of-pocket expenses of the
Administrative Agent or such Bank (or transferee) and taxes and without interest
(other than any interest paid by the relevant Governmental Authority with
respect to such refund) (all as determined in the Administrative Agent's or
Bank's sole discretion); provided, however, that the Borrower, upon the request
                         --------  -------
of the Administrative Agent or such Bank (or transferee), agrees to repay the
amount paid over to the Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent or
such Bank (or transferee) in the event the Administrative Agent or such Bank (or
transferee) is required to repay such refund to such Governmental Authority.
Nothing contained in this Section 2.16 shall require the Administrative Agent or
any Bank to make available its Tax returns (or any other information relating to
its Taxes which it deems confidential) to the Borrower or any other Person.

     Section 2.17 Tax Forms. If any Bank or any entity that is or hereafter
                  ---------
becomes a Bank is organized under the laws of a jurisdiction outside the United
States (a "Foreign Bank"), such Person shall provide the Administrative Agent
and the other parties hereto with the Prescribed Forms on the date it becomes a
party hereto, and from time to time thereafter if requested by the affected
party hereto or the Administrative Agent. The Administrative Agent, if required
by applicable law or regulation, may withhold taxes from payments under the Loan
Documents at the applicable rate in the case of payments to or for any Foreign
Bank. Any Person which is not a "United States person" (as defined in Section
7701 (a)(30) of the Code) that seeks to become a Bank under this Agreement shall
provide the Prescribed Forms to the Company and the Administrative Agent prior
to becoming a Bank hereunder, and no such Person may become a Bank hereunder if
such Person is unable to deliver the Prescribed Forms.

     Section 2.18 Voluntary Reduction of Commitment. Upon at least three (3)
                  ---------------------------------
Business Day's prior written notice, the Company shall have the right, without
premium or penalty, to reduce ratably in part or terminate in whole the unused
portions of the respective Commitments of the Banks, provided that each partial
                                                     --------
reduction shall be in the aggregate amount of $5,000,000 or any integral
multiple of $1,000,000 in excess thereof and provided further that the Company
                                             -------- -------
shall not have the right to terminate or reduce in part an unused portion of the
Revolving Loan Commitments that could or may be required to pay or refinance
Swingline Advances or Letter of Credit Liabilities then outstanding.

     Section 2.19 Fees.  Subject to Section 11.08 hereof, the Company agrees to
                  ----              -------------
pay the following fees (the "Fees"):
                             ----

     (a)  The Company shall pay to the Administrative Agent for the ratable
account of the Banks a commitment fee (the "Commitment Fee") for, in the case of
                                            --------------
Revolving Loan Commitments, the period from and including the Execution Date to
the Revolving Loan Maturity Date calculated on the basis of a 360-day year and
computed on the daily average of the Unutilized Commitment of each Bank at the
rate for Commitment Fees set forth in the definition of Margin and, in the case
of the Tranche A Term Loan Commitment, the period from and including the
Execution Date to May 31, 2000 calculated on such basis and computed on the
unused portion of the Tranche A Term Loan Commitment during such period.
Commitment Fees shall be due and payable in arrears on each Designated Payment
Date commencing on the first such date following the Execution Date and on the
Revolving Loan Maturity Date.

     (b)  The Company shall pay to the Administrative Agent for the benefit of
the Banks (and, in the case of clause (z) below, for the benefit of the Issuing
Bank) an annual fee (the "Letter of Credit Fee") in respect of each Letter of
                          --------------------
Credit issued hereunder equal to (y) the greater of (i) the then effective
Eurodollar Margin for Revolving Loans multiplied by the face amount of such
Letter of Credit (computed on the basis of the actual number of days elapsed
over a year of 360 days) or (ii) $500, plus (z) 0.125% per annum multiplied by
the face amount of such Letter of Credit, to be paid to the Issuing Bank. Such
fees shall be payable quarterly in arrears on each Designated Payment Date
commencing May 31, 2000 and on the Maturity Date.

     Section 2.20  Replacement of Banks.  If any Bank requests compensation
                   --------------------
under Section 2.10(f), 2.14, 2.16 or 3.04 or if any Bank notifies the Company
      ---------------  ----  ----    ----
that it cannot fund certain Loans or is unable to deliver the Prescribed Forms,
or if any Bank defaults in its obligation to fund Advances or issue Letters of
Credit hereunder, then the Company may, at its sole expense and effort, upon
notice to such Bank and the Administrative Agent, require such Bank to assign
and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 11.10), all its interests, rights and
                          -------------
obligations under this Agreement to an assignee that shall assume such
obligations (which assignee may be another Bank, if a Bank accepts such
assignment); provided that (i) the Company shall have received the prior written
consent of the Administrative Agent, which consent shall not unreasonably be
withheld, (ii) such Bank shall have received payment of an amount equal to the
outstanding principal of its Advances, accrued interest thereon, accrued fees
and all other amounts payable to it hereunder, from the assignee (to the extent
of such outstanding principal and accrued interest and fees) or the Company (in
the case of all other amounts) and (iii) in the case of any such assignment
resulting from a claim for compensation under Section 2.10(f), 2.14 or 2.16,
                                              ---------------  ----    ----
such assignment will result in a reduction in such compensation.  A Bank shall
not be required to make any such assignment and delegation if, prior thereto, as
a result of a waiver by such Bank or otherwise, the circumstances entitling the
Company to require such assignment and delegation cease to apply.

     Section 3.01  Letters of Credit.
                   -----------------

     (a)  Subject to and upon the terms and conditions herein set forth, the
Issuing Bank will, at any time and from time to time on or after the Execution
Date and prior to the Revolving Loan Maturity Date, promptly following its
receipt of a Letter of Credit Request and Application for Letter of Credit,
issue for the account of the Company or any of the Guarantors and in support of
the obligations of the Company or any of its Subsidiaries, one or more
irrevocable letters of credit (all such letters of credit together with the
Existing Letters of Credit collectively, the "Letters of Credit"), up to a
                                              -----------------
maximum amount outstanding at any one time for all Letters of Credit and
Existing Letters of Credit equal to $50,000,000, provided that the Issuing Bank
                                                 --------
shall not issue any Letter of Credit if at the time of such issuance: (i) the
stated amount of such Letter of Credit is greater than an amount which, when
added to the Outstanding Revolving Credit would exceed the Total Revolving Loan
Commitment; or (ii) the expiry date or, in the case of any Letter of Credit
containing an expiry date that is extendible at the option of the Issuing Bank,
the initial expiry date of such Letter of Credit is a date that is later than
the Revolving Loan Maturity Date, unless such Letter of Credit is secured by
cash.

     (b)  The Issuing Bank shall neither renew nor permit the renewal of any
Letter of Credit if any of the conditions precedent to such renewal set forth in
Section 4.02 are not satisfied or, after giving effect to such renewal, the
- ------------
expiry date of such Letter of Credit would be a date that is later than the
Revolving Loan Maturity Date.

     (c)  The Company, the Administrative Agent and the Banks acknowledge that
Chase and Bankers Trust Company have issued, for the account of the Company, the
Existing Letters of Credit described on Schedule 3.01 hereto. Upon the
                                        -------------
Execution Date, the Letters of Credit outstanding shall be that amount equal to
the aggregate stated amount of the Existing Letters of Credit, and the amount
available for Loans and Letters of Credit under the Commitments shall be reduced
by such amount so long as said Letters of Credit are outstanding and the amount
available under each Bank's Commitment shall be reduced by such Bank's
percentage participation of such amount. If the Company or any of the Guarantors
desires to extend the existing expiry date of any Existing Letter of Credit, or
request a substitute letter of credit be issued for any reason in respect of any
Existing Letter of Credit, the Company or any of the Guarantors shall submit to
the Issuing Bank a Letter of Credit Request as provided in Section 3.02(a).

     Section 3.02  Letters of Credit Requests.
                   --------------------------

     (a)  Whenever the Company desires that a Letter of Credit be issued for its
account or that the existing expiry date shall be extended, it shall deliver to
the Issuing Bank (with copies to be sent to the Administrative Agent) in the
case of a Letter of Credit to be issued, at least three (3) Business Days' prior
written request therefor and in the case of the extension of the existing expiry
date of any Letter of Credit, at least five days prior to the date on which the
Issuing Bank must notify the beneficiary thereof that the Issuing Bank does not
intend to extend such existing expiry date. Each such request shall be executed
by the Company and shall be in the form of Exhibit 3.02 attached

hereto (each a "Letter of Credit Request") and shall be accompanied by an
                ------------------------
application for Letter of Credit therefor, completed to the reasonable
satisfaction of the Issuing Bank, and such other certificates, documents and
other papers and information as the Issuing Bank or any Bank (through the
Administrative Agent) may reasonably request. Each Letter of Credit shall be
denominated in U.S. dollars, shall expire no later than the date specified in
Section 3.01, shall not be in an amount greater than is permitted under clauses
- ------------
(i) or (ii) of Section 3.01(a) and shall be in such form as may be reasonably
               ---------------
approved from time to time by the Issuing Bank and the Company.

     (b)  The delivery of each Letter of Credit Request shall be deemed to be a
representation and warranty by the Company that such Letter of Credit may be
issued in accordance with, and will not violate the requirements of, this
Agreement or the terms of any other Indebtedness of the Company (including,
without limitation, the Indentures). Unless the Issuing Bank has received notice
from any Bank before it issues the respective Letter of Credit or extends the
existing expiry date of a Letter of Credit that one or more of the conditions
specified in Article IV are not then satisfied, or that the issuance of such
             ----------
Letter of Credit would violate this Agreement, then the Issuing Bank may issue
the requested Letter of Credit in accordance with the Issuing Bank's usual and
customary practices. Upon its issuance of any Letter of Credit or the extension
of the existing expiry date of any Letter of Credit, as the case may be, the
Issuing Bank shall promptly notify the Company, the Administrative Agent and
each Bank of such issuance or extension, which notice shall be accompanied by a
copy of the Letter of Credit actually issued or a copy of any amendment
extending the existing expiry date of any Letter of Credit, as the case may be,
provided that the failure of the Issuing Bank to give such notice or provide
such copy shall not affect the obligations of the Banks under Section 3.03.

     Section 3.03  Letter of Credit Participations.
                   -------------------------------

     (a)  All Obligations of the Company and the Guarantors with respect to all
Existing Letters of Credit and all Letters of Credit issued subsequent hereto
shall be deemed to have been sold and transferred by the Issuing Bank to each
Bank, and each Bank shall be deemed irrevocably and unconditionally to have
purchased and received from the Issuing Bank, without recourse or warranty, an
undivided interest and participation (to the extent of such Bank's percentage
participation in the Commitments) in each such Obligation, each substitute
letter of credit, each drawing made thereunder and the obligations of the
Company under this Agreement and the other Loan Documents with respect thereto,
and any security therefor or guaranty pertaining thereto including the Guaranty.

     (b)  The Issuing Bank shall have no obligation relative to the Banks other
than to confirm that any documents required to be delivered under such Letter of
Credit appear to have been delivered and that they appear to comply on their
face with the requirements of such Letter of Credit.

     (c)  In the event that the Issuing Bank makes any payment under any Letter
of Credit, the same shall be considered an Alternate Base Rate Advance of a
Revolving Loan without further action by any Person. The Issuing Bank shall
promptly notify the Administrative Agent, which shall promptly notify each Bank
thereof. Each Bank shall immediately pay to the Administrative Agent for the
account of the Issuing Bank the amount of such Bank's percentage participation
of such Advance. If any Bank shall not have so made its percentage participation
available to the

                                       40

Administrative Agent, such Bank agrees to pay interest thereon, for each day
from such date until the date such amount is paid at the lesser of the Federal
Funds Effective Rate and the Highest Lawful Rate.

     (d)  The Issuing Bank shall not be liable for, and the obligations of the
Company and the Banks to make payments to the Administrative Agent for the
account of the Issuing Bank with respect to Letters of Credit shall not be
subject to, any qualification or exception whatsoever, including any of the
following circumstances:

          (i)   any lack of validity or enforceability of this Agreement or any
          of the other Loan Documents;

          (ii)  the existence of any claim, setoff, defense or other right which
          the Company may have at any time against a beneficiary named in a
          Letter of Credit, any transferee of any Letter of Credit, the
          Administrative Agent, the Issuing Bank, any Bank, or any other Person,
          whether in connection with this Agreement, any Letter of Credit, the
          transactions contemplated herein or any unrelated transactions
          (including any underlying transaction between the Company and the
          beneficiary named in any such Letter of Credit);

          (iii) any draft, certificate or any other document presented under
          the Letter of Credit proving to be forged, fraudulent, invalid or
          insufficient in any respect or any statement therein being untrue or
          inaccurate in any respect;

          (iv)  the surrender or impairment of any security for the performance
          or observance of any of the terms of any of the Loan Documents; or

          (v)   the occurrence of any Default or Event of Default.

     (e)  The Issuing Bank shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by the Issuing Bank's gross negligence or willful
misconduct. It is the express intention of the parties hereto that the Issuing
Bank, its officers, directors, employees and agents shall be indemnified and
held harmless from any action taken or omitted by such Person under or in
connection with any Letter of Credit or any related draft or document arising
out of or resulting from such Person's sole or contributory negligence. The
Company agrees that any action taken or omitted by the Issuing Bank under or in
connection with any Letter of Credit or the related drafts or documents, if done
in accordance with the standards of care specified in the Uniform Customs and
Practice for Documentary Credits (1993 Revision), International Chamber of
Commerce, Publication No. 500 (and any subsequent revisions thereof approved by
a Congress of the International Chamber of Commerce and adhered to by the
Issuing Bank) and, to the extent not inconsistent therewith, the Uniform
Commercial Code of the State of Texas, shall not result in any liability of the
Issuing Bank to the Company.

affecting this Agreement or any Letter of Credit, and the result of any of the
foregoing is to increase the cost to any Bank of issuing, maintaining or
participating in any Letter of Credit, or reduce the amount received or

deemed by such Bank to be material, then, from time to time, the Company shall
pay to the Administrative Agent for the account of such Bank such additional
amount or amounts as will reasonably compensate such Bank for such increased
cost or reduction by such Bank.

     (b)  Each Bank will notify the Company through the Administrative Agent of
any event occurring after the date of this Agreement which will entitle such
Bank to compensation pursuant to subsection (a) above, as promptly as
practicable. A certificate of a Bank setting forth in reasonable detail such
amount or amounts as shall be necessary to compensate such Bank as specified in
subsection (a) above may be delivered to the Company (with a copy to the
Administrative Agent) and shall be conclusive absent manifest error. The Company
shall pay to the Administrative Agent for the account of such Bank the amount
shown as due on any such certificate within 30 days after its receipt of the
same. No Bank shall be entitled to recover any costs pursuant to this Section
                                                                      -------

                                   GUARANTY
                                   --------

     Section 8.01  Guaranty. In consideration of, and in order to induce the
                   --------
Banks to make the Loans hereunder, the Guarantors hereby absolutely,
unconditionally and irrevocably, jointly and severally guarantee the punctual
payment and performance when due, whether at stated maturity, by acceleration or
otherwise, of the Obligations, and all other obligations and covenants of the
Company now or hereafter existing under this Agreement, the Notes and the other
Loan Documents whether for principal, interest (including interest accruing or
becoming owing both prior to and subsequent to the commencement of any
proceeding against or with respect to the Company under any chapter of the
Bankruptcy Code), Fees, commissions, expenses (including reasonable attorneys'
fees and expenses) or otherwise, and all reasonable costs and expenses, if any,
incurred by the Administrative Agent or any Bank in connection with enforcing
any rights under this Guaranty (all such obligations being the "Guaranteed
Obligations"), and agree to pay any and all reasonable expenses incurred by each
Bank and the Administrative Agent in enforcing this Guaranty; provided that
notwithstanding anything contained herein or in any of the Loan Documents to the
contrary, the maximum liability of each Guarantor hereunder and under the other
Loan Documents shall in no event exceed such Guarantor's Maximum Guaranteed
Amount, and provided further, each Guarantor shall be unconditionally required
to pay all amounts demanded of it hereunder prior to any determination of such
Maximum Guaranteed Amount and the recipient of such payment, if so

                                       63
<PAGE>

required by a final non-appealable order of a court of competent jurisdiction,
shall then be liable for the refund of any excess amounts. If any such rebate or
refund is ever required, all other Guarantors (and the Company) shall be fully
liable for the repayment thereof to the maximum extent allowed by applicable
law. This Guaranty is an absolute, unconditional, present and continuing
guaranty of payment and not of collectibility and is in no way conditioned upon
any attempt to collect from the Company or any other action, occurrence or
circumstance whatsoever. Each Guarantor agrees that the Guaranteed Obligations
may at any time and from time to time exceed the Maximum Guaranteed Amount of
such Guarantor without impairing this Guaranty or affecting the rights and
remedies of the Banks hereunder.

     Section 8.02  Continuing Guaranty. Each Guarantor guarantees that the
                   -------------------
Guaranteed Obligations will be paid strictly in accordance with the terms of
this Agreement, the Notes and the other Loan Documents. Each Guarantor agrees
that the Guaranteed Obligations and Loan Documents may be extended or renewed,
and Loans repaid and reborrowed in whole or in part, without notice to or assent
by such Guarantor, and that it will remain bound upon this Guaranty
notwithstanding any extension, renewal or other alteration of any Guaranteed
Obligations or Loan Documents, or any repayment and reborrowing of Loans. To the
maximum extent permitted by applicable law, the obligations of each Guarantor
under this Guaranty shall be absolute, unconditional and irrevocable, and shall
be performed strictly in accordance with the terms hereof under any
circumstances whatsoever, including:

     (a)  any extension, renewal, modification, settlement, compromise, waiver
or release in respect of any Guaranteed Obligations;

     (b)  any extension, renewal, amendment, modification, rescission, waiver or
release in respect of any Loan Documents;

     (c)  any release, exchange, substitution, non-perfection or invalidity of,
or failure to exercise rights or remedies with respect to, any direct or
indirect security for any Guaranteed Obligations, including the release of any
Guarantor or other Person liable on any Guaranteed Obligations;

     (d)  any change in the corporate existence, structure or ownership of the
Company, any Guarantor, or any insolvency, bankruptcy, reorganization or other
similar proceeding affecting the Company, such Guarantor, any other Guarantor or
any of their respective assets;

     (e)  the existence of any claim, defense, set-off or other rights or
remedies which such Guarantor at any time may have against the Company, or the
Company or such Guarantor may have at any time against the Administrative Agent,
any Bank, any other Guarantor or any other Person, whether in connection with
this Guaranty, the Loan Documents, the transactions contemplated thereby or any
other transaction other than by the payment in full by the Company of the
Guaranteed Obligations after the termination of the Commitments of the Banks;

     (f)  any invalidity or unenforceability for any reason of this Agreement or
other Loan Documents, or any provision of law purporting to prohibit the payment
or performance by the

                                       64
<PAGE>

Company, such Guarantor or any other Guarantor of the Guaranteed Obligations or
Loan Documents, or of any other obligation to the Administrative Agent or any
Bank; or

     (g)  any other circumstances or happening whatsoever, whether or not
similar to any of the foregoing.

     Section 8.03  Effect of Debtor Relief Laws. If after receipt of any payment
                   ----------------------------
of, or proceeds of any security applied (or intended to be applied) to the
payment of all or any part of the Guaranteed Obligations, the Administrative
Agent or any Bank is for any reason compelled to surrender or voluntarily
surrenders (under circumstances in which it believes it could reasonably be
expected to be so compelled if it did not voluntarily surrender), such payment
or proceeds to any Person (a) because such payment or application of proceeds is
or may be avoided, invalidated, declared fraudulent, set aside, determined to be
void or voidable as a preference, fraudulent conveyance, fraudulent transfer,
impermissible set-off or a diversion of trust funds or (b) for any other similar
reason, including (i) any judgment, decree or order of any court or
administrative body having jurisdiction over the Administrative Agent, any Bank
or any of their respective properties or (ii) any settlement or compromise of
any such claim effected by the Administrative Agent or any Bank with any such
claimant (including the Company), then the Guaranteed Obligations or part
thereof intended to be satisfied shall be reinstated and continue, and this
Guaranty shall continue in full force as if such payment or proceeds have not
been received, notwithstanding any revocation thereof or the cancellation of any
Note or any other instrument evidencing any Guaranteed Obligations or otherwise;
and the Guarantors, jointly and severally, shall be liable to pay the
Administrative Agent and the Banks, and hereby do indemnify the Administrative
Agent and the Banks and hold them harmless for the amount of such payment or
proceeds so surrendered and all expenses (including reasonable attorneys' fees,
court costs and expenses attributable thereto) incurred by the Administrative
Agent or any Bank in the defense of any claim made against it that any payment
or proceeds received by the Administrative Agent or any Bank in respect of all
or part of the Guaranteed Obligations must be surrendered. The provisions of
this paragraph shall survive the termination of this Guaranty, and any
satisfaction and discharge of the Company by virtue of any payment, court order
or any federal or state law.

     Section 8.04  Waiver of Subrogation. Notwithstanding any payment or
                   ---------------------
payments made by any Guarantor hereunder, or any set-off or application by the
Administrative Agent or any Bank of any security or of any credits or claims, no
Guarantor will assert or exercise any rights of the Administrative Agent or any
Bank or of such Guarantor against the Company to recover the amount of any
payment made by such Guarantor to the Administrative Agent or any Bank hereunder
by way of any claim, remedy or subrogation, reimbursement, exoneration,
contribution, indemnity, participation or otherwise arising by contract, by
statute, under common law or otherwise, and such Guarantor shall not have any
right of recourse to or any claim against assets or property of the Company, in
each case unless and until the Obligations of the Company guaranteed hereby and
then due have been fully and finally satisfied. Until such tim e, each Guarantor
hereby expressly waives any right to exercise any claim, right or remedy which
such Guarantor may now have or hereafter acquire against the Company that arises
under this Agreement or any other Loan Document or from the performance by any
Guarantor of the Guaranty hereunder including any claim, remedy or right of
subrogation, reimbursement, exoneration, contribution, indemnification or
participation in any

                                       65
<PAGE>

claim, right or remedy of the Administrative Agent or any Bank against the
Company or any Guarantor, or any security that the Administrative Agent or any
Bank now has or hereafter acquires, whether or not such claim, right or remedy
arises in equity, under contract, by statute, under common law or otherwise. If
any amount shall be paid to a Guarantor by the Company or another Guarantor
after payment in full of the Obligations, and the Obligations shall thereafter
be reinstated in whole or in part and the Administrative Agent or any Bank
forced to repay any sums received by any of them in payment of the Obligations,
this Guaranty shall be automatically reinstated and such amount shall be held in
trust for the benefit of the Administrative Agent and the Banks and shall
forthwith be paid to the Administrative Agent to be credited and applied to the
Guaranteed Obligations, whether matured or unmatured. The provisions of this
paragraph shall survive the termination of this Guaranty, and any satisfaction
and discharge of the Company by virtue of any payment, court order or any
federal or state law.

     Section 8.05  Subordination. If any Guarantor becomes the holder of any
                   -------------
indebtedness payable by the Company or another Guarantor, each Guarantor hereby
subordinates all indebtedness owing to it from the Company or such other
Guarantor to all indebtedness of the Company to the Administrative Agent and the
Banks, and agrees that during the continuance of any Event of Default and at the
request of the Administrative Agent it shall not accept any payment on the same
until payment in full of the Obligations of the Company under this Agreement and
the other Loan Documents after the termination of the Commitments of the Banks
and shall in no circumstance whatsoever attempt to set-off or reduce any
obligations hereunder because of such indebtedness. If any amount shall
nevertheless be paid in violation of the foregoing to a Guarantor by the Company
or another Guarantor prior to payment in full of the Guaranteed Obligations,
such amount shall be held in trust for the benefit of the Administrative Agent
and the Banks and shall forthwith be paid to the Administrative Agent to be
credited and applied to the Guaranteed Obligations, whether matured or
unmatured.

     Section 8.06  Waiver. Each Guarantor hereby waives promptness, diligence,
                   ------
notice of acceptance and any other notice with respect to any of the Guaranteed
Obligations and this Guaranty and waives presentment, demand of payment, notice
of intent to accelerate, notice of dishonor or nonpayment and any requirement
that the Administrative Agent or any Bank institute suit, collection proceedings
or take any other action to collect the Guaranteed Obligations, including any
requirement that the Administrative Agent or any Bank protect, secure, perfect
or insure any Lien against any property subject thereto or exhaust any right or
take any action against the Company or any other Person or any collateral (it
being the intention of the Administrative Agent, the Banks and each Guarantor
that this Guaranty is to be a guaranty of payment and not of collection). It
shall not be necessary for the Administrative Agent or any Bank, in order to
enforce any payment by any Guarantor hereunder, to institute suit or exhaust its
rights and remedies against the Company, any other Guarantor or any other
Person, including others liable to pay any Guaranteed Obligations, or to enforce
its rights against any security ever given to secure payment thereof. Each
Guarantor hereby expressly waives to the maximum extent permitted by applicable
law each and every right to which it may be entitled by virtue of the suretyship
laws of the State of Texas, including any and all rights it may have pursuant to
Rule 31, Texas Rules of Civil Procedure, Section 17.001 of the Texas Civil
Practice and Remedies Code and Chapter 34 of the Texas Business and Commerce
Code. Each Guarantor hereby waives marshaling of assets and liabilities, notice
by the

                                       66
<PAGE>

Administrative Agent or any Bank of any indebtedness or liability to which such
Bank applies or may apply any amounts received by such Bank, and of the
creation, advancement, increase, existence, extension, renewal, rearrangement or
modification of the Guaranteed Obligations. Each Guarantor expressly waives, to
the extent permitted by applicable law, the benefit of any and all laws
providing for exemption of property from execution or for valuation and
appraisal upon foreclosure.

     Section 8.07  Full Force and Effect. This Guaranty is a continuing guaranty
                   ---------------------
and shall remain in full force and effect until all of the Obligations of the
Company under this Agreement and the other Loan Documents and all other amounts
payable under this Guaranty have been paid in full (after the termination of the
Commitments of the Banks). All rights, remedies and powers provided in this
Guaranty may be exercised, and all waivers contained in this Guaranty may be
enforced, only to the extent that the exercise or enforcement thereof does not
violate any provisions of applicable law which may not be waived.

     Section 8.08  Negative Pledge. No Guarantor will create any lien on its
                   ---------------
assets to any other Person during the pendency of this Agreement except for
liens that would be permitted by Section 7.04 nor will any of them enter any
                                 ------------
agreement with any Person not to grant liens on or pledge assets to the
Administrative Agent, except for restrictions in leases, licenses, purchase
money loans and other contracts entered into in the ordinary course of business
and limited to the specific property subject to such lease, license, loan or
contract.

appoints and authorizes the Administrative Agent to act on its behalf and to
exercise such powers under this Agreement and the other Loan Documents as are
specifically delegated to or required of the Administrative Agent by the terms

to be taken by it or them under or in connection with this Agreement, the Notes

have no liability to the Banks for actions and omissions under this Section
resulting from the Administrative Agent's sole ordinary or contributory
negligence.

     (b)  Without limitation of the generality of the foregoing, the
Administrative Agent: (i) may treat the payee of each Note and the Obligations

     Section 10.03  Administrative Agent and Affiliates; Bank of America and
                    --------------------------------------------------------
Affiliates.  Without limiting the right of any other Bank to engage in any
- ----------
business transactions with the Company or any of its Affiliates, with respect to
their Commitments, the Loans made by them and the Notes issued to them, Bank of
America and each other Bank who may become the Administrative Agent shall have
the same rights and powers under this Agreement and its Notes as any other Bank
and may exercise the same as though it was not the Administrative Agent; and the
term "Bank" or "Banks" shall, unless otherwise expressly indicated, include Bank
of America and any such other Bank, in their individual capacities. Bank of
America, each other Person who becomes the Administrative Agent and their
respective Affiliates may be engaged in, or may hereafter engage in, one or more
loan, letter of credit, leasing or other financing activity not the subject of
this Agreement (collectively, the "Other Financings") with the Company, any

Subsidiary or any of its Affiliates, or may act as trustee on behalf of, or

                                                    ----------------
responsibility to account therefor to the Banks. Without limiting the rights and
remedies of the Banks specifically set forth herein, no other Bank by virtue of
being a Bank hereunder shall have any interest in (a) any Other Activities, (b)
any present or future guaranty by or for the account of the Company not
contemplated or included herein, (c) any present or future offset exercised by
the Administrative Agent in respect of any such Other Activities, (d) any
present or future property taken as security for any such Other Activities or
(e) any property now or hereafter in the possession or control of the
Administrative Agent which may be or become security for the Obligations of the
Company hereunder and under the Notes by reason of the general description of
indebtedness secured, or of property contained in any other agreements,
documents or instruments related to such Other Activities; provided, however,
                                                           --------  -------

     Section 10.04  Banks' Credit Decision.  Each Bank acknowledges and agrees
                    ----------------------
that it has, independently and without reliance upon the Administrative Agent or
any other Bank and based on the financial statements referred to in Section 5.07
                                                                    ------------
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Bank also
acknowledges and agrees that it will, independently and without reliance upon
the Administrative Agent or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement and the
other Loan Documents.

     Section 10.05  Administrative Agent's Indemnity.
                    --------------------------------

     (a)  The Administrative Agent shall not be required to take any action
hereunder or to prosecute or defend any suit in respect of this Agreement, the
Notes or any other Loan Document unless indemnified to the Administrative
Agent's satisfaction by the Banks against loss, cost, liability and expense. If
any indemnity furnished to the Administrative Agent shall become impaired, it
may call for additional indemnity and cease to do the acts indemnified against
until such additional indemnity is given. In addition, the Banks agree to
indemnify the Administrative Agent (to the extent not reimbursed by the
Company), ratably according to the respective aggregate principal amounts of the
Notes then held by each of them (or if no Notes are at the time outstanding,
ratably according to the respective amounts of the Commitments), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against the
Administrative Agent in any way relating to or arising out of this Agreement or
any action taken or omitted by the Administrative Agent under this Agreement,
the Notes and the other Loan Documents. Without limitation of the foregoing,
each Bank agrees to reimburse the Administrative Agent promptly upon demand for
its ratable share of any out-of-pocket expenses (including reasonable counsel
fees) incurred by the Administrative Agent in connection with the preparation,
execution, administration, or enforcement of, or legal advice in respect of
rights or responsibilities under, this Agreement, the Notes and the other Loan
Documents to the extent that the Administrative Agent is not reimbursed for such
expenses by the Company. The provisions of this Section shall survive the
termination of this Agreement, the payment of the Obligations and/or the
assignment of any of the Notes.

     (b)  Notwithstanding the foregoing, no Bank shall be liable under this
Section to the Administrative Agent for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements due to the Administrative Agent resulting from the
Administrative Agent's gross negligence or willful misconduct. Each Bank agrees,
however, that it expressly intends, under this Section, to indemnify the
Administrative Agent ratably as aforesaid for all such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements arising out of or resulting from the Administrative Agent's sole
ordinary or contributory negligence.

     Section 10.06  Successor Administrative Agent.  The Administrative Agent
                    ------------------------------
may resign at any time by giving written notice thereof to the Banks and the
Company and may be removed as Administrative Agent under this Agreement, the
Notes and the other Loan Documents at any time

                                       72
<PAGE>

with or without cause by the Majority Banks. Upon any such resignation or
removal, the Majority Banks shall have the right to appoint a successor
Administrative Agent with the approval of the Company (so long as no Default or
Event of Default then exists), which shall not be unreasonably withheld. If no
successor Administrative Agent shall have been so appointed by the Majority
Banks, and shall have accepted such appointment, within 30 calendar days after
the retiring Administrative Agent's giving of notice of resignation or the
Majority Banks' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Banks, appoint a successor
Administrative Agent with the approval of the Company (so long as no Default or
Event of Default then exists), which shall not be unreasonably withheld, which
shall be a commercial bank organized under the laws of the United States of
America or of any state thereof and having a combined capital and surplus of at
least $50,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder and under the Notes and the other Loan Documents by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under this Agreement, the
Notes and the other Loan Documents. After any retiring Administrative Agent's
resignation or removal as Administrative Agent hereunder and under the Notes and
the other Loan Documents, the provisions of this Article X shall inure to its
                                                 ---------
benefit as to any actions taken or omitted to be taken by it while it
was Administrative Agent under this Agreement, the Notes and the other Loan
Documents.

     Section 10.07  Notice of Default.  The Administrative Agent shall not be
                    -----------------
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent shall have received notice
from a Bank or the Company referring to this Agreement, describing such Default
or Event of Default and stating that such notice is a "notice of default." If
the Administrative Agent receives such notice, the Administrative Agent shall
give notice thereof to the Banks; provided, however, if such notice is received
                                  --------  -------
from a Bank, the Administrative Agent also shall give notice thereof to the
Company. The Administrative Agent shall be entitled to take action or refrain
from taking action with respect to such Default or Event of Default as provided
in Section 10.01 and Section 10.02.

thereby), nor consent to any departure by the Company herefrom or therefrom,

Securitizations) where the Administrative Agent may release the affected
guaranty, assets or Accounts without Bank approval. Releases of Collateral as
part of an asset sale that is not currently permitted by Section 7.02 but which

does not constitute a release of all or substantially all of the Collateral
shall require approval of Majority Banks. Further, no provisions of Article III

                    -------------------
the Administrative Agent to exercise, and no delay in exercising, any right
hereunder, under any Note or under any other Loan Document shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right, or
any abandonment or discontinuance of any steps to enforce such right, preclude

Bank and each Affiliate thereof and their respective directors, officers,

proposed use by the Company of the proceeds of any extension of credit hereunder
or any investigation, litigation or other proceeding (including any threatened
investigation or proceeding) relating to the foregoing or any of the other Loan
Documents, and the Company shall reimburse each Bank and each Affiliate thereof
and their respective directors, officers, employees and agents, upon demand for
any expenses (including legal fees) reasonably incurred in connection with any
such investigation or proceeding; but excluding any such losses, liabilities,

intention of the parties hereto that each Person to be indemnified hereunder

in Article IX, each Bank is hereby authorized at any time and from time to time,

subsidiary or Affiliate, to or for the credit or the account of the Company or
any Guarantor against any and all the Obligations of the Company or any
Guarantor now or hereafter existing under this Agreement and the other Loan
Documents and other obligations of the Company or any Guarantor held by such
Bank, irrespective of whether or not such Bank shall have made any demand under
this Agreement, its Note or the Obligations and although the Obligations may be
unmatured. Each Bank agrees promptly to notify the Company or Guarantors as the
case may be, after any such set-off and application made by such Bank, provided,

and application. The rights of each Bank under this Section are in addition to
other rights and remedies (including other rights of setoff) which such Bank may
have.

     Section 11.07  Governing Law.  This Agreement, all Notes, the other Loan
                    -------------
Documents and all other documents executed in connection herewith shall be
deemed to be contracts and agreements executed by the Company and each Bank
under the laws of the State of Texas and of the United States of America and for
all purposes shall be construed in accordance with, and governed by, the laws of
said state and of the United States of America. Without limitation of the
foregoing, nothing in this Agreement, or in the Notes or in any other Loan
Document shall be deemed to constitute a waiver of any rights which any Bank may
have under applicable federal legislation relating to the amount of interest
which such Bank may contract for, take, receive or charge in respect of the Loan
and the Loan Documents, including any right to take, receive, reserve and charge
interest at the rate allowed by the law of the state where any Bank is located.
The Administrative Agent, each Bank and the Company further agree that insofar
as the provisions of Texas Finance Code, Chapter 303, as amended, are applicable
to the determination of the Highest Lawful Rate with respect to the Notes and
the Obligations hereunder and under the other Loan Documents, the weekly rate
ceiling of such Article, as described in Article 1D.003 of the Texas Credit
Title, shall be applicable; provided, however, that to the extent permitted by
                            --------  -------
such Article, the Administrative Agent may from time to time by notice to the
Company revise the election of such interest rate ceiling as such ceiling
affects the then current or future balances of the Loans. The provisions of the
Texas Finance Code, Chapter 346 do not apply to this Agreement, any Note issued
hereunder or the other Loan Documents.

     Section 11.08  Interest.  Each provision in this Agreement and each other
                    --------
Loan Document is expressly limited so that in no event whatsoever shall the
amount paid, or otherwise agreed to be paid, to the Administrative Agent or any
Bank, or charged, contracted for, reserved, taken or

                                       76
<PAGE>

received by the Administrative Agent or any Bank, for the use, forbearance or
detention of the money to be loaned under this Agreement or any Loan Document or
otherwise (including any sums paid as required by any covenant or obligation
contained herein or in any other Loan Document which is for the use, forbearance
or detention of such money), exceed that amount of money which would cause the
effective rate of interest to exceed the Highest Lawful Rate, and all amounts
owed under this Agreement and each other Loan Document shall be held to be
subject to reduction to the effect that such amounts so paid or agreed to be
paid, charged, contracted for, reserved, taken or received which are for the
use, forbearance or detention of money under this Agreement or such Loan
Document shall in no event exceed that amount of money which would cause the
effective rate of interest to exceed the Highest Lawful Rate. Anything in any
Note or any other Loan Document to the contrary notwithstanding, the Company
shall not be required to pay unearned interest on any Note and the Company shall
not be required to pay interest on the Obligations at a rate in excess of the
Highest Lawful Rate, and if the effective rate of interest which would otherwise
be payable under such Note and such Loan Documents would exceed the Highest
Lawful Rate, or if the holder of such Note shall receive any unearned interest
or shall receive monies that are deemed to constitute interest which would
increase the effective rate of interest payable by the Company under such Note
and the other Loan Documents to a rate in excess of the Highest Lawful Rate,
then (a) the amount of interest which would otherwise be payable by the Company
shall be reduced to the amount allowed under applicable law and (b) any unearned
interest paid by the Company or any interest paid by the Company in excess of
the Highest Lawful Rate shall in the first instance be credited on the principal
of the Obligations of the Company (or if all such Obligations shall have been
paid in full, refunded to the Company). It is further agreed that, without
limitation of the foregoing, all calculations of the rate of interest contracted
for, reserved, taken, charged or received by any Bank under the Notes and the
Obligations and under the other Loan Documents are made for the purpose of
determining whether such rate exceeds the Highest Lawful Rate, and shall be
made, to the extent permitted by usury laws applicable to such Bank, by
amortizing, prorating and spreading in equal parts during the period of the full
stated term of the Notes and this Agreement all interest at any time contracted
for, charged or received by such Bank in connection therewith. Furthermore, in
the event that the maturity of any Note or other obligation is accelerated or in
the event of any required or permitted prepayment, then such consideration that
constitutes interest under applicable law may never include more than the
maximum amount allowed by applicable law and excess interest, if any, provided
for in this Agreement, any Note or otherwise shall be canceled automatically as
of the date of such acceleration or prepayment and, if theretofore paid, shall
be refunded to the Company.

hereto, whether so expressed or not, provided that the Commitments of the Banks

transfer any of its rights or obligations hereunder.

     (b)  Any of the Banks may sell participations to one or more banks,

Lien, setoff or claim of any kind against the Company as a result of which the
unpaid principal portion of the Notes and the Obligations held by it shall be
proportionately less than the unpaid principal portion of the Notes and
Obligations held by any other Bank, it shall be deemed to have simultaneously
purchased from such other Bank a participation in the Notes and Obligations held
by such other Bank, in the amount required to render such amounts proportional;
provided, however, that if any such purchase or purchases or adjustments shall
- --------  -------
be made pursuant to this Section and the payment giving rise thereto shall

have been stricken herefrom and the remainder will have the same force and
effectiveness as if such part or parts had never been included herein.

be taken with respect to the Collateral.

     (f)  Except as otherwise provided in this subsection (f), each Debtor shall
continue to collect, at its own reasonable expense, all amounts due or to become
due such Debtor under the Receivables. In connection with such collections, each
Debtor may take (and, upon the occurrence and continuance of an Event of Default
and so long as it is continuing and has not been waived at the Secured Party's
direction, shall take) such action as such Debtor or the Secured Party may deem
necessary or advisable to enforce collection of the Receivables; provided, that
the Secured Party shall have the right at any time during the existence of an
Event of Default, upon written notice to each Debtor of its intention to do so,
to notify the account debtors or obligors under any Receivables of the
assignment of such Receivables to the Secured Party and to direct such account
debtors or obligors to make payment of all amounts due or to become due to such
Debtor thereunder directly to the Secured Party and, upon such notification and
at the expense of such Debtor, to enforce collection of any such Receivables,
and to adjust, settle or compromise the amount or payment thereof, in the same
manner and to the same extent as such Debtor might have done. After receipt by
the Debtors of the notice from the Secured Party referred to in the proviso to
the preceding sentence, (i) all amounts and proceeds (including instruments)
received by the Debtors in respect of the Receivables shall be received in trust
by the Debtors, shall be segregated from other funds of the Debtors and shall be
forthwith paid over to the Secured Party in the same form as so received (with
any necessary endorsement) to be held as cash collateral and either (A) released
to the Debtors so long as no Default or Event of Default shall be continuing or
(B) if any Default or Event of Default shall be continuing, applied as provided
in Section 12(b), and (ii) the Debtors shall not adjust, settle or compromise
   -------------
the amount or payment of any Receivable, or release wholly or partly any account
debtor or obligor
<PAGE>

thereof, or allow any credit or discount thereon, except with the prior written
consent of the Secured Party.

     (g)  The Debtors shall keep substantially all the Inventory (other than
such Inventory sold in the ordinary course of business or Inventory in transit
or Inventory placed at the location of its installation pending installation and
payment therefor) at the places therefor specified in Section 5(a) or, upon
                                                      ------------
notice within 30 days after such move to the Secured Party, at such other places
in jurisdictions where all action required by Section 6(a) shall have been or
                                              ------------
shall be taken with respect to such Inventory.

     (h)  The Debtors shall promptly upon request furnish to the Secured Party a
statement respecting any material loss or damage to any of the Inventory or any
other of the Collateral and will permit the Secured Party to inspect the
Collateral upon reasonable notice during normal business hours.

     SECTION  7.  Secured Party Appointed Attorney-in-Fact. Each Debtor hereby
                  ----------------------------------------
irrevocably appoints the Secured Party as the Debtors' attorney-in-fact, with
full authority in the place and stead of the Debtors and in the name of the
Debtors, from time to time in the Secured Party's sole reasonable discretion
after the occurrence of an Event of Default and during the continuance thereof,
to take any action and to execute any instrument which the Secured Party may
deem reasonably necessary or advisable to accomplish the purposes of this
Agreement, including:

     (a)  to obtain insurance required to be maintained pursuant to the Credit
Agreement,

     (b)  to ask, demand, collect, sue for, recover, compromise, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral,

     (c)  to receive, endorse, and collect any drafts or other instruments,
documents and chattel paper, in connection with clause (b) above,

     (d)  to file any claims or take any action or institute any proceedings
which the Secured Party may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce the rights of the Secured Party
with respect to any of the Collateral, and

     (e)  to sell, transfer, assign, or otherwise deal in or with the Collateral
or the proceeds thereof, as provided herein and subject to applicable law, as
fully and effectually as if the Secured Party were the absolute owner thereof;
provided, that the Secured Party shall give the Debtors not less than ten (10)
days' prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral, except any Collateral which is perishable
or
<PAGE>

threatens to decline speedily in value or is of a type customarily sold on a
recognized market. The Debtors agree that such notice constitutes "reasonable
notification" within the meaning of (S) 9.504(c) of the UCC.

     SECTION 8.  Secured Party May Perform.  If any Debtor fails to perform any
                 -------------------------
agreement contained herein, the Secured Party may itself perform, or cause
performance of, such agreement, and the expenses of the Secured Party incurred
in connection therewith shall be payable upon demand by such Debtor and if not
paid shall bear interest at the Default Rate set forth in the Credit Agreement.

     SECTION 9.  The 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 or any other Party to exercise any such
powers. In regard to any Debtor, except for reasonable care in the custody of
any Collateral in its possession and the accounting for moneys actually received
by it hereunder, neither the Secured Party nor any other party shall have any
duty as to any Collateral or as to the taking of any necessary steps to preserve
rights against prior 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.

     SECTION 10. Remedies.  If any Event of Default shall have occurred and be
                 --------
continuing:

     (a)  The Secured Party may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party on default under the UCC
and the Secured Party may also (i) require any Debtor to, and each Debtor hereby
agrees that it will at its reasonable expense and upon request of the Secured
Party forthwith, 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, and (ii) without notice except as specified
below, sell the Collateral or any part thereof in one or more parcels at public
or private sale, at any of the Secured Party's offices or elsewhere, for cash or
on credit, and upon such other terms as may be commercially reasonable. Each
Debtor agrees that, to the extent notice of sale shall be required by law, at
least ten (10) days' prior notice to the Debtors 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. 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.
<PAGE>

     (b)  Any cash received by the Secured Party shall be applied to repay the
Secured Obligations. Any surplus of such cash or cash proceeds held by the
Secured Party and remaining after payment in full of all the Secured Obligations
shall be paid over to the Debtors or to whomsoever may be lawfully entitled to
receive such surplus.

     SECTION 11.  Amendments.  No amendment or waiver of any provision of this
                  ----------
Agreement, nor consent to any departure by the Debtors herefrom, shall in any
event be effective unless the same shall be in writing and signed by the Secured
Party with the requisite consent of the Debtors, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.

     SECTION 12.  Addresses for Notices.  All notices and other communications
                  ---------------------
provided for hereunder shall be given in the manner and at the addresses and
telecopy numbers as set forth in the Credit Agreement, and shall become
effective, as specified in the Credit Agreement.

     SECTION 13.  Termination; Reinstatement.  (a) Each Debtor agrees that this
                  --------------------------
Agreement and the Liens granted hereunder shall terminate when, but only when,
all Secured Obligations have been fully paid and performed (except for
indemnification obligations not yet due) and all Banks' commitments under the
Loan Documents have expired or been terminated.  At any time thereafter upon the
Debtor's request, the Secured Party shall (i) promptly reassign and redeliver,
(or cause to be reassigned and redelivered) to the Debtors, or to such Person or
Persons as the Debtors shall designate in writing, against receipt, such of the
Collateral (if any) as shall not have been sold or otherwise applied by the
Secured Party pursuant to the terms hereof and shall still be held by it
hereunder and (ii) terminate any financing statements with respect to the
Collateral or any part thereof.  Any such reassignment shall be without recourse
upon, or representation or warranty by, the Secured Party (other than that the
Secured Party has not sold, encumbered or otherwise transferred any interest in
the Collateral except as provided in this Agreement) and shall be at the sole
reasonable cost and expense of the Debtors.

     (b)  This Agreement shall continue to be effective or be reinstated, as the
case may be, if at any time any amount received by the Secured Party in respect
of the Secured Obligations is rescinded or must otherwise be restored or
returned by the Secured Party upon the filing of any bankruptcy proceeding by or
of the Debtors or upon the appointment of any intervenor or conservator of, or
trustee or similar official for, the Debtors or any substantial part of their
assets, or otherwise, all as though such payments had not been made.

     SECTION 14.  Waiver of Marshaling.  All rights of marshaling of assets of
                  --------------------
the Debtors, including any such right with respect to the Collateral, are hereby
waived by the Debtors.

     SECTION 15.  Limitation by Law.  All rights, remedies and powers provided
                  -----------------
in this Agreement may be exercised only to the extent that the exercise thereof
does not violate any
<PAGE>

applicable provision of law, and all the provisions of this Agreement are
intended to be subject to all applicable mandatory provisions of law which may
be controlling and to be limited to the extent necessary so that they will not
render this Agreement invalid, unenforceable, in whole or in part, or not
entitled to be recorded, registered or filed under the provisions of any
applicable law.

     SECTION 16.  Separability.  Should any clause, sentence, paragraph,
                  ------------
subsection or Section of this Agreement be judicially declared to be invalid,
unenforceable or void, such declaration will not have the effect of invalidating
or voiding the remainder of this Agreement, and the parties hereto agree that
the part or parts of this Agreement so held to be invalid, unenforceable or void
will be deemed to have been stricken herefrom by the Secured Party hereto, and
the remainder will have the same force and effectiveness as if such stricken
part or parts had never been included herein.

     SECTION 17.  No Waiver; Remedies.  No failure on the part of the Secured
                  -------------------
Party to exercise, and no delay in exercising, any right hereunder shall operate
as a waiver thereof; nor shall any single or partial exercise of any right
hereunder preclude any other or further exercise thereof or the exercise of any
other right. The remedies herein provided are cumulative and not exclusive of
any remedies provided by law.

     SECTION 18.  Partial Release of Security Interest. Upon the request of the
                  ------------------------------------
Debtors in connection with any sale, transfer or other disposition of property
or assets permitted hereunder or under any Loan Document, so long as no Event of
Default under any of the Loan Documents has occurred and is continuing, the
Secured Party shall execute and deliver to the Debtors duly executed releases or
partial releases, as applicable, of any security interest it may have in such
property or assets, in form and substance reasonably satisfactory to the Secured
Party and the applicable Debtor.

     SECTION 19.  Continuing Security Interest.  This Agreement shall create a
                  ----------------------------
continuing security interest in the Collateral and shall (a) remain in full
force and effect until payment in full of the Secured Obligations, (b) be
binding upon each Debtor, its successors and assigns, and (c) inure to the
benefit of the Secured Party and its respective successors, transferees and
assigns. Without limiting the generality of the foregoing clause (c), the
Secured Party may assign or otherwise transfer all or a portion of its
interests, rights and obligations under any Note held by it pursuant to the
Credit Agreement or pursuant to any Loan Document.  Upon the payment in full of
the Secured Obligations, the Liens granted hereby shall terminate and all rights
to the Collateral shall revert to the Debtors.  Upon any such termination, the
Secured Party will, at the Debtors' reasonable expense, promptly execute and
deliver to the Debtors such documents as the Debtors shall reasonably request to
evidence such termination.  Any Subsidiary of the Company that executes an
Adoption Agreement after the date of this Agreement shall, upon such execution,
become a party hereto as a Debtor.
<PAGE>

     SECTION 20.  Survival of Representations and Warranties.  All
                  ------------------------------------------
representations and warranties contained in this Agreement or made in writing by
or on behalf of the Debtors in connection herewith are true and correct in all
material respects when made or deemed made and shall survive the execution and
delivery of this Agreement until repayment of the Secured Obligations. Any
investigation by the Secured Party shall not diminish in any respect whatsoever
its rights to rely on such representations and warranties.

     SECTION 21.  Governing Law; Terms.  This Agreement shall be governed by and
                  --------------------
construed in accordance with the laws of the State of Texas and the applicable
laws of the United States of America, except as required by mandatory provisions
of law and except to the extent that the validity or perfection of the security
interest hereunder, or remedies hereunder, in respect of any particular
collateral are governed by the laws of a jurisdiction other than the State of
Texas.

     SECTION 22.  Inconsistencies. In the event of any irreconcilable
                  ---------------
inconsistences between any provision of this Agreement and any provision of the
Credit Agreement and/or the Loan Documents, the provisions of this Agreement
shall control.

     SECTION 23.  Counterparts.  This Agreement may be executed in any number of
                  ------------
counterparts, and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which when
taken together shall constitute but one and the same agreement.

          SECTION 3.  Security for Obligations.  This Agreement secures on a
                      ------------------------

shall be accompanied by duly executed instruments of transfer or assignment
specifying the certificate and the issuer to which it relates, in blank, all in
form and substance satisfactory to the Secured Party.  With respect to any
Pledged Collateral in which any Pledgor has any right, title or interest and
that constitutes an uncertificated security, such Pledgor will cause the issuer
thereof (i) to register the Secured Party as the registered owner or lien holder
of such security, (ii) to agree in writing with such Pledgor and the Secured
Party that such Pledgor will comply with instructions with respect to such
security originated by the Secured Party without further consent of such
Pledgor, such agreement to be in form and substance satisfactory to the Secured
Party, or (iii) take other action necessary or appropriate to attach and perfect
the Secured Party's security interest in  accordance with applicable law to the
Secured Party's satisfaction.

the date hereof. Each other Pledgor has its chief executive office at the
location shown on Schedule II hereto or at such other locations as disclosed to
                  -----------
the Secured Party after the date hereof.

          (b)   The Pledged Shares have been duly authorized and validly issued
and are fully paid and non-assessable.

          (c)   The Pledgors are the legal and beneficial owners of the Pledged

encumbrance except for the Permitted Liens and other Liens not prohibited under
the Credit Agreement.

          (d)   The actions taken under Section 4 pursuant to this Agreement and
                                        ---------
the filing of financing statements, if applicable, creates a valid and perfected
first priority security
<PAGE>

interest in the Pledged Shares (subject only to Permitted Liens and other Liens
not prohibited under the Credit Agreement), securing the payment of the Secured
Obligations.

          (e)  No authorization, approval, or other action by, and no notice to
or filing with, any governmental authority is required either (i) for the pledge
by the Pledgors of the Pledged Shares pursuant to this Agreement or for the
execution, delivery or performance of this Agreement by the Pledgors or (ii) for
the exercise by the Secured Party of the voting or other rights provided for in
this Agreement (except as may be required in connection with such disposition by
laws affecting the offering and sale of securities generally and except for
filings or other actions described herein relating to the attachment and
perfection of a security interest).

time to time, at the reasonable expense of the Pledgor, each Pledgor 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 Pledged
Collateral. Without limiting the generality of the foregoing, each Pledgor will
execute and file such financing or continuation statements, or amendments
thereto, and such other instruments or notices as the Secured Party may
reasonably request as being necessary or desirable in order to perfect and
preserve the security interests granted or purported to be granted hereby.

          (b)  Each Pledgor hereby authorizes the Secured Party for the benefit
of itself and the Banks to file one or more financing or continuation
statements, and amendments thereto, relative to all or any part of the Pledged
Collateral without the signature of such Pledgor, in each case where permitted
by law.  A carbon, photographic or other reproduction of any financing statement
executed by each Pledgor covering the Pledged Collateral or any part thereof
shall be sufficient as a financing statement where permitted by law.  The
Secured Party shall provide the Company with copies of all financing statements
that it files.

          (c)  Each Pledgor will furnish to the Secured Party from time to time
statements and schedules further identifying and describing the Pledged
Collateral as the Secured Party may reasonably request, all in reasonable
detail.

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)  Each Pledgor shall keep its principal place of business and chief
executive office and the office where it keeps its records concerning the
Pledged Collateral at the location or locations therefor specified in Section
                                                                      -------
5(a) or, upon prompt written notice after such move, to the Secured Party, at
- ----
such other locations in a jurisdiction where all action required by this Section
                                                                         -------

          SECTION 7.  Voting Rights.  (a) So long as no Event of Default shall
                      -------------
have occurred and be continuing, the Pledgors shall be entitled to exercise any
and all voting and other rights pertaining to the Pledged Collateral or any part
thereof for any purpose not inconsistent with the terms of this Agreement, the
Credit Agreement, or any Loan Documents.

          (b)  Upon the occurrence and during the continuance of an Event of
Default, upon notice by the Administrative Agent, all rights of the Pledgors to
exercise the voting rights which they would otherwise be entitled to exercise
pursuant to Section 7(a) hereof shall cease for so long as such Event of Default
            ------------
shall continue, and the Secured Party shall thereupon have the sole right to
exercise such voting rights.

          SECTION 8.  Dividends.  If dividends or other distributions with
                      ---------
respect to the Pledged Collateral are received by the Pledgors in violation of
the terms of the Loan Documents, such dividends shall be received in trust for
the benefit of the Secured Party for itself and for the benefit of the Banks,
shall be segregated from other funds of the Pledgors and shall be forthwith paid
over to the Secured Party as Pledged Collateral in the same form as so received.

          SECTION 9.  Transfers and Other Liens; Additional Shares.  (a) The
                      --------------------------------------------
Pledgors shall not: (i) sell, assign (by agreement, operation of law or
otherwise) or otherwise dispose of, or grant any option with respect to, any of
the Pledged Collateral, except for transfers not prohibited by the Credit
Agreement or (ii) create or permit to exist any Lien upon or with respect to any
of the Pledged Collateral, except for the Permitted Liens and other Liens not
prohibited by the Credit Agreement.

          (b)  The Pledgors agree that they will (i) cause the Persons that

such acquisition (directly or indirectly) thereof, any and all additional
Capital Stock of such Person constituting Pledged Shares.

          (c)  Notwithstanding the foregoing or any other provision hereof, any
Subsidiary may be merged with or liquidate into any other Subsidiary whose
Capital Stock has
<PAGE>

been pledged pursuant hereto or pursuant to any Adoption Agreement or other
Security Document or with the Company, except that no Domestic Subsidiary shall
be permitted to merge or liquidate into a Foreign Subsidiary.

          SECTION 10.  Secured Party Appointed Attorney-in-Fact.  The Pledgors
                       ----------------------------------------
hereby irrevocably appoint the Secured Party for the benefit of itself and for
the benefit of the Banks as the Pledgors' attorney-in-fact, with full authority
in the place and stead of the Pledgors and in the name of the Pledgors, from
time to time in the Secured Party's sole reasonable discretion after the
occurrence of an Event of Default and during the continuance thereof, to take
any action and to execute any instrument which the Secured Party may reasonably
deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation, to receive, endorse and collect all certificates
made payable to the Pledgors representing any dividend or other distribution in
respect of the Pledged Collateral or any part thereof.  Upon the occurrence and
during the continuance of an Event of Default, the Secured Party shall have the
right, in its sole discretion and without notice to the Pledgors, to transfer to
or to register in the name of the Secured Party or any of its nominees, for the
benefit of itself and the Banks, any or all of the Pledged Collateral.

          SECTION 11.  Secured Party May Perform.  If any Pledgor fails to
                       -------------------------
perform any agreement contained herein, the Secured Party may itself perform, or
cause performance of, such agreement, and the reasonable expenses of the Secured
Party incurred in connection therewith shall be payable upon demand by such
Pledgor and if not paid shall bear interest at the Default Rate set forth in the
Credit Agreement.

          SECTION 12.  The Secured Party's Duties.  The powers conferred on the
                       --------------------------
Secured Party hereunder are solely to protect its interest and the interests of
Banks in the Pledged Collateral and shall not impose any duty upon it to
exercise any such powers.  In regard to any Pledgor, except for reasonable care
in the custody of any Pledged Collateral in its possession and the accounting
for moneys actually received by it hereunder, neither the Secured Party nor any
other party shall have any duty as to any Pledged Collateral or as to the taking
of any reasonably necessary steps to preserve rights against prior parties or
any other rights pertaining to any Pledged Collateral. The Secured Party shall
be deemed to have exercised reasonable care in the custody and preservation of
the Pledged Collateral in its possession if the Pledged 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 (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Pledged Collateral, whether or not the Secured Party has or is deemed to have
knowledge of such matters or (b) taking any necessary steps to preserve rights
against any parties with respect to any Pledged Collateral.

          SECTION 13.  Remedies upon Default.  If any Event of Default shall
                       ---------------------
have occurred and be continuing:
<PAGE>

          (a)  The Secured Party for itself and for the benefit of the Banks may
exercise in respect of the Pledged Collateral, in addition to other rights and
remedies provided for herein or otherwise available to it, all the rights and
remedies of a secured party under the UCC (whether or not the UCC applies to the
affected Pledged Collateral), and the Secured Party may also, without notice
except as specified below, sell the Pledged Collateral or any part thereof in
one or more parcels at public or private sale, at any exchange, broker's board
or at any of the Secured Party's offices or elsewhere, for cash, or for future
delivery, and upon such other terms as are commercially reasonable.  Each
Pledgor agrees that, to the extent notice of sale shall be required by
applicable law, at least ten (10) days' notice to the Pledgors of the time and
place of any public sale or of the time after which any private sale is to be
made shall constitute reasonable notification thereof.  The Secured Party shall
not be obligated to make any sale of Pledged 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 cash received by the Secured Party shall be applied to repay
the Secured Obligations.  Any surplus of such cash or cash proceeds held by the
Secured Party and remaining after payment in full of all the Secured Obligations
shall be paid over to the Pledgors or to whomsoever may be lawfully entitled to
receive such surplus.

          (c)  In connection with the sale of any Pledged Collateral, the
Secured Party is authorized, but not obligated, to limit prospective purchasers
to the extent deemed necessary or desirable by the Secured Party to render such
sale exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"), and any applicable state laws and regulations,
              --------------
and no sale so made in good faith by the Secured Party shall be deemed not to be
"commercially reasonable" because so made.

          (d)  All rights and remedies of the Secured Party expressed herein are
in addition to all other rights and remedies possessed by the Secured Party
under the Credit Agreement and any other agreement or instrument relating to the
Obligations.

          SECTION 14.  Additional Provisions Concerning Sales of Pledged
                       -------------------------------------------------
Collateral.  (a) The Pledgors recognize that the Secured Party may be unable to
- ----------
effect a public sale of any or all of the Pledged Collateral by reason of
certain prohibitions contained in the laws of any jurisdiction outside the
United States or in the Securities Act and applicable state securities laws, but
may instead be compelled to resort to one or more private sales thereof to a
restricted group of purchasers who shall be obligated to agree, among other
things, to acquire such Pledged Collateral for their own account for investment
and not with a view to the distribution or resale thereof.  The Pledgors
acknowledge and agree that any such private sale may result in prices and other
terms less favorable to the seller than if such sale were a public sale and,
notwithstanding such circumstances, agree that any such private sale shall, to
the extent permitted by law, be deemed to have been made in a commercially
reasonable manner.  The Secured Party shall not be under any obligation to delay
a sale of any of the Pledged Collateral for the period of time
<PAGE>

necessary to permit the Pledgors to register such securities under the laws of
any jurisdiction outside the United States, under the Securities Act or under
any applicable state securities laws, even if the Pledgors would agree to do so.

          (b)  The Pledgors further agree to do or cause or be done, to the
extent that the Pledgors may legally do so, all such other acts and things as
may be necessary to make such sales or resales of any portion or all of the
Pledged Collateral valid and binding and in compliance with any and all
applicable laws, regulations, orders, writs, injunctions, decrees or awards of
any and all courts, arbitrators or governmental authorities, domestic or
foreign, having jurisdiction over any such sale or sales, all at the Pledgors'
expense; provided, however, that the Pledgors shall not be obligated to register
such securities under the laws of any jurisdiction including, without
limitation, under the Securities Act.  The Pledgors further agree that a breach
of any of the covenants contained in this Section shall cause irreparable injury
to the Secured Party, and that the Secured Party has no adequate remedy at law
in respect of such breach and, as a consequence, agrees that each and every
covenant contained in this Section shall be specifically enforceable against the
Pledgors, and, to the fullest extent permitted by law, the Pledgors hereby waive
and agree not to assert as a defense against an action for specific performance
of such covenants that (i) the Pledgors' failure to perform such covenants shall
not cause irreparable injury to the Secured Party or the Banks or (ii) the
Secured Party for itself and on behalf of the Banks has an adequate remedy at
law in respect of such breach.

          SECTION 15.  Indemnity and Expenses.  (a) The Pledgors hereby agree to
                       ----------------------
indemnify the Secured Party from and against any and all claims, losses and
liabilities growing out of or resulting from enforcement of this Agreement,
except claims, losses or liabilities, if any, resulting from the Secured Party's
gross negligence or willful misconduct.  SUBJECT TO THE FOREGOING, IT IS THE
EXPRESS INTENTION OF THE PLEDGORS THAT THE SECURED PARTY SHALL BE INDEMNIFIED
AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES,
JUDGMENTS OR EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY CONTRIBUTORY
OR ORDINARY CONCURRENT NEGLIGENCE OF ANY SUCH PERSON.

          (b)  The Pledgors shall, upon demand, but subject to the terms of the
Credit Agreement, pay to the Secured Party the amount of any and all reasonable
expenses, including the reasonable fees and expenses of the such party's counsel
and of its experts, that the Secured Party may incur in connection with (i)
administration of this Agreement, (ii) the evaluation, appraisal, custody or
preservation of, or sale of, collection from, or other realization upon any of
the Pledged Collateral, (iii) the exercise or enforcement of any of the rights
of the Secured Party for itself and for the benefit of the Banks hereunder or
(iv) the failure by the Pledgors to perform or observe any of the provisions of
this Agreement.  Each Pledgor agrees to pay interest on any sums payable to the

<PAGE>

          SECTION 16.  Amendments, Etc.  No amendment or waiver of any provision
                       ---------------
of this Agreement, nor consent to any departure by the Pledgors herefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Secured Party with the requisite consent of all other Banks, if applicable, and
the Pledgors, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose of which given.

          SECTION 17.  Addresses for Notices.  All notices and other
                       ---------------------
communications to any Pledgor provided for hereunder shall be given in the
manner and at the addresses and telecopy numbers as set forth for the Company in
the Credit Agreement, and shall become effective as specified in the Credit
Agreement and/or Loan Documents.

          SECTION 18.  Waiver of Marshaling.  All rights of marshaling of assets
                       --------------------
of the Pledgors, including any such right with respect to the Pledged
Collateral, are hereby waived by the Pledgors.

          SECTION 19.  Limitation by Law.  All rights, remedies and powers
                       -----------------
provided in this Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable provision of law, and all the provisions
of this Agreement are intended to be subject to all applicable mandatory
provisions of law which may be controlling and to be limited to the extent
necessary so that they shall not render this Agreement invalid, unenforceable,
in whole or in part, or not entitled to be recorded, registered or filed under
the provisions of any applicable law.

          SECTION 20.  Severability.  Should any clause, sentence, paragraph,
                       ------------
subsection or Section of this Agreement be judicially declared to be invalid,
unenforceable or void, such decision shall not have the effect of invalidating
or voiding the remainder of this Agreement, and the parties hereto agree that
the part or parts of this Agreement so held to be invalid or unenforceable shall
be deemed to have been stricken herefrom by the parties hereto, and the
remainder of this Agreement shall have the same force and effectiveness as if
such stricken part or parts had never been included herein.

          SECTION 21.  Termination; Reinstatement.  (a)  Each Pledgor agrees
                       --------------------------
that this Agreement and the Liens granted hereunder shall terminate when, but
only when, all Secured Obligations have been fully and finally paid (except for
indemnification obligations not yet due) and performed and all Banks'
Commitments under the Credit Agreement and/or Loan Documents have expired or
been terminated.

          (b)  Upon the sale or transfer by any Pledgor of any Pledged
Collateral that is permitted under the Credit Agreement to any Person that is
not a Pledgor, or, upon the effectiveness of any release of the Liens granted
hereunder in any Pledged Collateral pursuant to Section 11.01 of the Credit
Agreement, the Lien granted in such Pledged Collateral shall be automatically
released.
<PAGE>

          (c)  In connection with any release under paragraphs (a) or (b) above,
upon the Pledgor's request, the Secured Party shall (i) promptly reassign and
redeliver (or cause to be reassigned and redelivered) to the Pledgors, or to
such Person or Persons as the Pledgors shall designate in writing, against
receipt, such released Pledged Collateral (if any) as shall not have been sold
or otherwise applied by the Secured Party for the benefit of itself or the Banks
pursuant to the terms hereof and shall still be held by it hereunder, and (ii)
terminate any financing statements with respect to the Pledged Collateral or any
part thereof.  Any such reassignment shall be without recourse upon, or
representation or warranty by the Secured Party (other than that the Secured
Party for the benefit of itself and the Banks has not sold, encumbered or
otherwise transferred any interest in the Collateral except as provided in this
Agreement) and shall be at the sole reasonable cost and expense of the Pledgors.

          (d)  This Agreement shall continue to be effective or be reinstated,
as the case may be, if at any time any amount received by the Secured Party or
any other of the Banks in respect of the Secured Obligations is rescinded or
must otherwise be restored or returned by the Secured Party or such other Banks
upon the filing of any bankruptcy proceeding by or of the Pledgors or upon the
appointment of any intervenor or conservator of, or trustee or similar official
for, the Pledgors or any substantial part of their assets, or otherwise, all as
though such payments had not been made.

          SECTION 22.  No Waiver; Remedies.  No failure on the part of the
                       -------------------
Secured Party to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by applicable law.

          SECTION 23.  Continuing Security Interest; Transfer of the Notes.
                       ---------------------------------------------------
This Agreement creates a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the full and final payment
and performance of the Secured Obligations (except for indemnification
obligations not yet due) and the Commitments of the Banks have been terminated,
(b) be binding upon each Pledgor, its successors and assigns and (c) inure to
the benefit of the Secured Party for the benefit of itself and the Banks and
their respective permitted successors, transferees and assigns.  Without
limiting the generality of the foregoing clause (c), any of the Banks may assign
or otherwise transfer all or a portion of  its interests, rights and obligations
in the Pledged Collateral held by it pursuant to the Credit Agreement, or
pursuant to any Loan Document, to any other Person in accordance with the terms
of the Credit Agreement, and such other Person shall thereupon become vested
with all the benefits in respect thereof granted to the Secured Party for itself
and for the benefit of the Banks herein or otherwise.  Upon the termination of
the Secured Obligations, the Liens granted hereby in accordance with the
foregoing shall revert to Pledgors, and the Secured Party will, at the Pledgors'
sole cost and expense, promptly execute and deliver to the Pledgor such
documents as the Pledgor shall reasonably request to evidence such termination.
Any Subsidiary of the Company that executes a counterpart of an Adoption
Agreement after the date of this Agreement shall, upon such execution, become a
party hereto as a Pledgor.
<PAGE>

          SECTION 24.  Security Interest Absolute.  All rights of the Secured
                       --------------------------
Party for itself and for the benefit of Banks and security interests hereunder,
and all obligations of the Pledgors hereunder, shall be absolute and
unconditional irrespective of:

          (a)  any lack of validity or enforceability of the Credit Agreement,
any of the Notes, or any other Loan Document;

          (b)  any change in the time, manner or place or payment of, or in any
other term of, all or any of the Secured Obligations, or any other amendment or
waiver of or any consent to any departure from the Credit Agreement, any of the
Notes, or any other Loan Documents;

          (c)  any exchange, release or non-perfection of any other collateral,
or any release or amendment or waiver of or consent to departure from any
guaranty  for all or any of the Secured Obligations; or

          (d)  any other circumstance which might otherwise constitute a defense
available to, or a discharge of, the Pledgors or any other third party.

          SECTION 25.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND
                       -------------
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA, EXCEPT AS REQUIRED BY MANDATORY PROVISIONS
OF LAW AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY
INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF

inconsistences between any provision of this Security Agreement and any
provision of the Credit Agreement and/or the Loan Documents, the provisions of
this Agreement shall control.

                       ------------
number of counterparts, and by different parties hereto in separate counterparts
either in original form or by telecopy, each of which when so executed shall be
deemed to be an original and all of which when taken together shall constitute
but one and the same agreement.

                               February 22, 2000

To (i) each of the Banks party to the
Credit Agreement dated as of February 22, 2000
among Group Maintenance America Corp.,
a Teas corporation (the "Borrower"), such Banks,
Bank of America, N.A., as Administrative
Agent, Chase Bank of Texas, National Association,
as Syndication Agent, First Union National Bank,
as Documentation Agent and others ("Credit Agreement"),
and (ii) such Administrative Agent, such Syndication Agent
and such Documentation Agent (the "Agents")

Ladies and Gentlemen:

We have acted as counsel to Group Maintenance America Corp., a Texas corporation
(the "Borrower") and certain Subsidiaries of the Borrower in connection with the
Credit Agreement. As used herein, (i) the term "Subsidiary Obligors" means the
Subsidiaries of the Borrower party to the Credit Agreement and (ii) the term
"Debtors" means the Borrower and each Subsidiary Obligor.

This opinion is the opinion referred to in Section 4.01(h)(i) of the Credit
Agreement. Capitalized terms used herein and defined in the Credit Agreement but
not defined herein are used herein as therein defined.

In connection with this opinion, we have examined copies of the following
documents (the "Documents"):

     (i)   a counterpart of the Credit Agreement executed by the Borrower;

     (ii)  the 20 notes dated February 22, 2000, each substantially in the form
           of Exhibit 2.02 (a-1) to the Credit Agreement, one executed by the
           Borrower for each Bank committed to make Revolving Loans (the
           "Revolving Notes");

     (iii) the 20 notes dated February 22, 2000, each substantially in the form
           of Exhibit 2.02(b) to the Credit Agreement, one executed by the
           Borrower for each Bank committed to make Tranche A Term Loans (the
           "Tranche A Term Notes");
<PAGE>

     (iv)   the 20 notes dated February 22, 2000, each substantially in the form
            of Exhibit 2.02(c) to the Credit Agreement, one executed by the
            Borrower for each Bank committed to make Tranche B Term Loans (the
            "Tranche B Term Notes");

     (v)    the note dated February 22, 2000 in substantially the form of
            Exhibit 2.02(a-2) to the Credit Agreement executed by the Borrower
            payable to Bank of America (the "Swingline Note");

     (vi)   the Security Agreement dated as of February 22, 2000, executed by
            the Borrower and the Subsidiary Obligors party thereto (the
            "Security Agreement");

     (vii)  the Pledge Agreement dated as of February 22, 2000, executed by the
            Borrower and the Subsidiary Obligors party thereto (the "Pledgors")
            (the "Pledge");

     (viii) the Merger Agreement;

     (ix)   the Investors' Rights Agreement; and

     (x)    the Subscription Agreement.

We have also examined originals or copies of such records and documents as we
have deemed necessary and relevant for purposes of this opinion. In addition, we
have relied on certificates or comparable documents of an officer of the
Borrower and various Subsidiary Obligors and of an officer of Building One
Services Corporation as to certain matters of fact relating to this opinion and
have made such investigations of law as we have deemed necessary and relevant as
a basis for this opinion. We have assumed (a) the genuineness of all signatures
(including, without limitation, those of the Borrower and each Subsidiary
Obligor), (b) the authenticity of all documents and records submitted to us as
originals, (c) the conformity to original documents and records of all documents
and records submitted to us as copies and (d) the truthfulness of all statements
of fact contained therein.

The Credit Agreement, the Revolving Notes, the Tranche A Term Notes, the Tranche
B Term Notes, the Swingline Note, the Subscription Agreement, the Security
Agreement, the Pledge, the Merger Agreement and the Investors' Rights Agreement
are collectively referred to as the "Borrower Documents". The Credit Agreement
and the Security Agreement are collectively referred to as the "Subsidiary
Obligor Documents".

Based on the foregoing and subject to the limitations and assumptions set forth
in this opinion, and having due regard for such legal considerations as we deem
relevant (including, without limitation, any relevant Texas and federal usury
laws), we are of the opinion that:

     1.   Each of the Borrower Documents constitutes the legal, valid and
binding obligation of the Borrower, enforceable against the Borrower in
accordance with its terms.

     2.   Each of the Subsidiary Obligor Documents constitutes the legal, valid
and binding obligation of each Subsidiary Obligor, enforceable against each
Subsidiary Obligor in accordance with its terms.

     3.   The Pledge constitutes the legal, valid and binding obligation of each
of the Pledgors, enforceable against each of the Pledgors in accordance with its
terms.


                                      -2-

     4. The Security Agreement creates a security interest in the Borrower's and
each Subsidiary Obligors' respective right, title and interest in the Collateral
(as defined in the Security Agreement) to the extent that a security interest in
such Collateral can be created under the Texas Business and Commerce Code
("UCC"). The form of the financing statement attached as Exhibit A hereto is in
proper form for filing with the Office of the Secretary of State of Texas,
assuming completion thereof with the correct name and mailing address of a
Debtor and due execution thereof by such Debtor. To the extent the UCC is
applicable to the creation and perfection of a security interest in such
Collateral and except for any such Collateral the perfection of a security
interest in which cannot be obtained by the filing pursuant to the UCC of a
financing statement with the Office of the Secretary of State of Texas, upon the
filing, pursuant to the provisions of the UCC, of a financing statement in the
form attached as Exhibit A hereto, completed with the correct name and mailing
address of a Debtor and duly executed by such Debtor, the security interests
referred to in the first sentence of this paragraph 4 in such Debtor's
respective right, title and interest in such Collateral will be perfected. To
the extent the UCC is applicable to the perfection of a security interest
created by the Pledge in certificated securities in registered form described in
the Pledge, perfection of such security interest in such securities may be
accomplished by delivery to the secured party, and the secured party taking
possession, in the State of Texas of the security certificates representing such
securities pursuant to the Pledge.

     5. The pledge of Capital Stock of the Subsidiary Obligors pursuant to the
Pledge does not violate any federal or Texas securities law, and registration of
any such Capital Stock under the Securities Act of 1933, as amended, or any
Texas securities laws is not required by such pledge.

     6. The making of the initial Loans on the Effective Date and the
application of the proceeds thereof by the Borrower do not violate Regulation T,
U or X of the Board of Governors of the Federal Reserve System.

     7. The choice of Texas and United States law to govern the Credit
Agreement, the Revolving Notes, the Tranche A Term Notes, the Tranche B Term
Notes, the Swingline Note, the Security Agreement and the Pledge is a valid
choice of law under the laws of the State of Texas.

     8.   The Merger has become effective.

     9. The principal of and interest on Loans made on the date hereof pursuant
to the Credit Agreement and Revolving Loans made pursuant to the Credit
Agreement constitute "Senior Debt" as defined in the BOSC Senior Subordinated
Notes Indenture, except to the extent that such principal or interest is held by
a Subsidiary (as that term is defined in the BOSC Senior Subordinated Notes
Indenture) of the Company or any shareholder (other than the Banks), director,
officer or employee of the Company or any such Subsidiary.

     The foregoing opinion is, with your concurrence, predicated on and
qualified in its entirety by the following:

     (a) We are members of the Bar of the State of Texas. The foregoing opinion
is based on and is limited to the law of the State of Texas and applicable
federal law of the United States. We render no opinion with respect to the law
of any other jurisdiction nor do we express any opinion with respect to the
antifraud provisions of any federal or state laws. In this regard, we call to
your attention the provisions of the Investors' Rights Agreement, the
Subscription Agreement and the Merger Agreement which provide that


                                      -3-
<PAGE>

those agreements shall be governed by the law of the State of New York or
Delaware, as the case may be.

     (b) No opinion is expressed as to the creation, existence, perfection or
priority of any Lien except as expressly stated in paragraph 4 above.
Furthermore, we express no opinion as to (i) goods not located in Texas, (ii)
goods which are installed in or affixed to, or become a part of a product or
mass with, goods which are not items of collateral; (iii) any collateral which
consists of fixtures, crops, timber, minerals and the like or accounts or
general intangibles resulting from the sale thereof or letters of credit; (iv)
any collateral that is not reasonably identified in the description of
collateral set forth in the relevant Documents; (v) any collateral in which the
Person purporting to grant a security interest does not have "rights" within the
meaning of (S) 9.203(a)(3) of the UCC; or (vi) perfection by filing with respect
to any collateral in the form of accounts, general intangibles, mobile goods or
investment property owned by a Person that is not located (within the meaning of
the UCC) in Texas.

     (c) Our opinion is subject to the effect of applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, preference,
liquidation, conservatorship or other similar law affecting creditor's rights
generally.

     (d) The enforceability of the Documents is subject to general principles of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law), and we express no opinion as to the availability of
specific performance or any other equitable remedy.

     (e) We express no opinion as to the legality, validity, binding effect or
enforceability of any provision in the Documents (i) purporting to restrict
access to courts or to legal or equitable remedies; (ii) purporting to establish
evidentiary standards; (iii) purporting to grant a right of set-off of moneys,
securities and other properties of Persons other than the Person granting such
right; (iv) providing for enforceability of any assignment of leases or rents
prior to the time that the lienholder obtains possession of the property covered
by any real property security document through foreclosure or appointment of a
receiver for the property covered thereby, or takes some action which is
judicially deemed to be the equivalent thereof; (v) purporting to irrevocably
appoint any Person as attorney-in-fact; (vi) purporting to permit any Person to
sell or otherwise dispose of any collateral except in compliance with applicable
law; (vii) purporting to establish standards for the care of collateral in a
secured party's possession other than as provided in (S) 9.207 of the UCC;
(viii) purporting to indemnify, defend or hold harmless any Person; (ix)
purporting to affect any right to trial by jury, venue or jurisdiction; or (x)
pertaining to subrogation rights, delay or omission of enforcement of rights or
remedies, severability or marshaling of assets.

     (f) We express no opinion as to any provision of the Documents insofar as
it provides that any Person purchasing a participation from a Bank pursuant
thereto may exercise set-off or similar rights with respect to such
participation.

     (g) We express no opinion as to the adequacy or accuracy of any description
of real or personal property, and we have assumed that such descriptions are
adequate and accurate. We express no opinion as to title or ownership of any
property.

     (h) We express no opinion as to the legality, validity, binding effect or
enforceability of any waiver under the Documents, or any consent thereunder,
relating to the rights of any party, or duties owing to them, which exist as a
matter of law except to the extent such party may legally so waive or consent
and has so waived and consented.

     (i) We have assumed, as to each Person (including, without limitation, the
Borrower, each Pledgor and each Guarantor) shown as being a party to any of the
Documents or any of the financing statements referred to in paragraph 4 above
(the "Financing Statements"), (i) that such Person is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized, (ii) that each of the Documents and Financing Statements to which
such Person is shown as a party has been duly authorized, executed and delivered
by such Person, (iii) that such Person has the requisite power and authority to
execute, deliver and perform its obligations under the Documents (and, where
relevant, the the Financing Statements) and will perform such obligations in
compliance with all laws and regulations applicable to it, (iv) that there are
neither suits, actions or proceedings pending against such Person nor judicial
or administrative orders, judgments, or decrees binding on such Person that
affect the legality, validity, binding effect or enforceability of the Documents
(or, where relevant, the Financing Statements) to which such Person is a party,
(v) that no consent, license, approval or authorization of, or filing or
registration with, any governmental authority is required for the valid
execution, delivery and performance of the Documents and Financing Statements,
and (vi) that the execution, delivery and performance of the Documents and
Financing Statements by such Person do not violate (1) any provision of any law
or regulation, (2) any order, judgment, writ, injunction, award or decree of any
court, arbitrator, or governmental authority, (3) the charter of bylaws of such
Person, or (4) any indenture, lease or other agreement to which such Person is a
party or by which such Person or any of its assets is bound. Furthermore, we
have assumed, as to each Person (other than the Borrower and each Subsidiary
Obligor) that each of the Documents to which such Person is shown as a party
constitutes the legal, valid and binding obligation of such Person enforceable
against such Person in accordance with its terms, subject to the type of
qualifications regarding enforceability as are set forth in this opinion. We
have also assumed (i) that each Bank will make each Loan for its own account in
the ordinary course of its commercial lending business and not with a view to,
or for sale in connection with, any distribution of the Notes and that no Bank
is participating in any such distribution and (ii) that the representation set
forth in Section 11.18 is true and correct as to each Bank.

     (j) We have assumed that the Agents and the Banks will comply with each
usury savings clause in the Documents and that neither any of the Agents nor any
of the Banks has taken, reserved, charged or received interest, or drill take,
reserve, charge or receive interest, except as provided in the Loan Documents.
We express no opinion as to the effect of the law of any jurisdiction other than
the State of Texas wherein any Bank or Agent may be located or wherein
enforcement of the Documents may be sought which limits the rates of interest
legally chargeable or collectible.

     (k) Our opinion is subject to the qualification that certain remedial
provisions of the Documents are or may be unenforceable in whole or in part, but
such possible unenforceability of such remedial provisions will not render any
Document inadequate for enforcing payment of the indebtedness that is evidenced
by such Document and for the practical realization of the principal rights and
benefits afforded by such Document.

     (1) In the case of property which becomes collateral after the date hereof,
(S) 552 of the Bankruptcy Code limits the extent to which property acquired by a
debtor after the commencement of a case under the Bankruptcy Code may be subject
to a security interest arising from a security agreement entered into by the
debtor before the commencement of such case.

     (m) We express no opinion as to the choice of law provisions in the
Investors' Rights Agreement, the Subscription Agreement and the Merger Agreement
or any choice of law provision insofar as it may

                                      -5-
<PAGE>

relate to any matter referred to in (S) 8.110 or (S) 9.103 of the UCC or any
financing statement. Furthermore, our opinion is subject to the effect of 12
U.S.C. (S) 85.

     (n) Insofar as any Document covers personal property, we call your
attention to (S) 9.311 of the UCC which states that a debtor's rights in
collateral may be voluntarily or involuntarily transferred (by way of sale,
creation of a security interest, attachment, levy, garnishment or other judicial
process) notwithstanding a provision in the security agreement prohibiting any
transfer or making the transfer constitute a default. Our opinion is subject to
the operation of (S) 9.311 of the UCC.

     (o) This opinion is given only as of the date hereof, and we have no
obligation to report to you or any other Person any fact or circumstance that
may hereafter come to our attention or any change in law. Without limiting the
generality of the foregoing, you are advised that filing of continuation
statements may be required to maintain perfection of security interests, and
perfection of security interests may terminate if the debtor changes its name,
identity, corporate structure or the jurisdiction of its chief executive office
or the collateral is moved to a new jurisdiction. As to any collateral as to
which possession is required for the perfection of a security interest, a
perfected security interest will not continue (with certain exceptions) if
possession is not maintained. Continuation of perfection of a security interest
in proceeds is limited to the extent set forth in the UCC.

     (p) We have assumed that (i) value has been given within the meaning of
(S) 9.203(a)(2) of the UCC and (ii) financing statements have been or will be
properly filed in the proper offices in the relevant jurisdictions for
perfection of the security interests in all collateral pursuant to the
provisions of local law in effect in the relevant jurisdictions.

This opinion (i) is to be delivered only to you and your assignees permitted
under the Documents, solely in your capacities identified as addressees of this
opinion, and only in connection with the transactions described above, (ii) does
not extend to you or your assignees when acting in any other capacity or to any
other Person without our prior express written consent, and (iii) may not be
quoted, circulated, or published, in whole or in part, or furnished to any other
Person (other than to independent auditors and attorneys, participants or
transferees, regulators or government agencies, or pursuant to a court order,
subpoena or other legal process) without our prior express written consent.

                               Very truly yours,


                               /s/ Bracewell & Patterson, L.L.P.

     4.  the incurrence on the date hereof of the entire committed amount of the

   To the Banks and the Agents
     referred to below:
   c/o Bank of America, N.A.
   901 Main Street, 14th Floor
   Dallas, Texas 75202

   Ladies and Gentlemen:

        As Senior Vice President and General Counsel of Group Maintenance
   America Corp., a Texas corporation (the "Company"), I have acted as counsel
   for the Company and its subsidiaries in connection with the Credit Agreement
   (the "Credit Agreement") dated as of February 22, 2000, among the Company,
   the subsidiaries of the Company party thereto (the "Subsidiaries"), the banks
   party thereto (the "Banks"), Chase Bank of Texas, National Association, as
   Syndication Agent (the "Syndication Agent"), First Union National Bank, as
   Documentation Agent (the "Documentation Agent"), and Bank of America, N.A.,
   as Administrative Agent (the "Administrative Agent" and, together with the
   Syndication Agent and the Documentation Agent, the "Agents"). This opinion is
   being delivered to you pursuant to Section 4.01(h) of the Credit Agreement.
   Unless otherwise defined herein, capitalized terms used herein have the
   definitions set forth in the Credit Agreement.

        I am familiar with the corporate proceedings of the Company and its
   Subsidiaries (the Company and such Subsidiaries are herein collectively
   referred to as the "GroupMAC Entities") relating to the authorization of the
   Transaction Documents and the Third Supplemental Indenture dated as of
   February 22, 2000 among BOSC, the Company, the subsidiaries of BOSC and the
   Company named therein, and IBJ Whitehall Bank & Trust Company (the
   "Supplemental Indenture"). In connection with the Credit Agreement, I have
   examined such statutes, corporate records and other instruments and documents
   as I have deemed necessary to examine for the purposes of this opinion.

        Based upon the foregoing and having regard to the legal considerations
   that I deem relevant, I am of the opinion that:
<PAGE>

February 22, 2000
Page 2



     1.   The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Texas and has all requisite
corporate power and authority to execute and deliver the Transaction Documents
and the Supplemental Indenture (collectively, the "GroupMAC Documents") to which
it is a party and to perform its obligations thereunder and to engage in its
business as presently conducted and as proposed to be conducted.

     2.   Except as described in Schedule 1 hereto, each Subsidiary (other than
GroupMAC Indiana, L.L.C. and GroupMAC Texas L.P.) is a corporation duly
incorporated, validly existing and in good standing under the jurisdiction of
its incorporation and has all requisite corporate power and authority to execute
and deliver the GroupMAC Documents to which it is a party and to perform its
obligations thereunder.

     3.   GroupMAC Indiana, L.L.C. is a limited liability company validly
existing and in good standing under the laws of the State of Indiana and has all
requisite power and authority to execute and deliver the GroupMAC Documents to
which it is a party.

     4.   GroupMAC Texas L.P. is a limited partnership validly existing and in
good standing under the laws of the State of Texas and has all requisite power
and authority to execute and deliver the GroupMAC Documents to which it is a
party. The general partner of GroupMAC Texas L.P. is GroupMAC Holding Corp. and
its limited partner is Greenway Investment Corp., both of which are wholly-owned
Subsidiaries of the Company.

     5.   Each of the Company, GroupMAC Management Co. and GroupMAC Holding
Corp. is qualified as a foreign corporation in each jurisdiction in which the
character of its business or its ownership of property requires such
qualification except where the failure to be so qualified would not have a
material adverse effect on the business or financial condition of the Company
and its Subsidiaries, taken as a whole.

     6.   Each of the GroupMAC Entities has duly authorized, by all necessary
corporate or other entity action on its part, its execution, delivery and
performance of the GroupMAC Documents to which it is a party and the
consummation of the transactions contemplated therein.

     7.   Each of the GroupMAC Entities has executed and delivered the GroupMAC
Documents to which it is a party.

     8.   The execution and delivery by each GroupMAC Entity of the GroupMAC
Documents to which it is a party, and the performance of its obligations
thereunder, (i) do not violate (A) any provision of any existing law or
regulation applicable to the GroupMAC Entities, (B) any order, judgment, writ,
injunction, award or decree, known to me after due inquiry, of any court,
arbitrator, or governmental authority applicable to the GroupMAC
<PAGE>

Entities, (C) the charter or by-laws or other organizational documents of any
GroupMAC Entity, or (D) any material indenture, material lease or other material
agreement, known to me after due inquiry, to which any GroupMAC Entity is a
party or by which any GroupMAC Entity or any of its assets is bound, and (ii) do
not result in, or require, the creation or imposition of any lien on any
property, assets or revenues of any GroupMAC Entity pursuant to the provisions
of any such indenture, lease or other agreement, except for liens created by, or
required to be created by, any of the Loan Documents.

     9.  No consent, license, approval or authorization of, or filing or
registration with, any governmental authority, which has not been obtained or
made, is required for the valid execution and delivery by each GroupMAC Entity
of the GroupMAC Documents to which it is a party or the performance by it of its
obligations thereunder.

     10.  To the best of my knowledge, there is no litigation, investigation or
administrative proceeding of or before any court, arbitrator or governmental
authority pending or threatened against any GroupMAC Entity (i) with respect to
the Loan Documents or (ii) that, in my reasonable judgment, would have a
material adverse effect on the business or financial condition of the Company
and its Subsidiaries, taken as a whole.

     11. The Company is not an "investment company" as defined in the Investment
Company Act of 1940 or a company "controlled" by an "investment company" within
the meaning of the Investment Company Act of 1940.

     12.  The Company is not a "holding company" or a "subsidiary company" of a
"holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

     I am a member of the State Bar of Texas, and the opinions expressed herein
are based upon and are limited exclusively to the laws of the State of Texas,
the General Corporation Law of the State of Delaware and the federal laws of the
United States of America. For purposes of this opinion I have assumed, with your
permission, that the laws of any state other than the laws of Texas and the
corporate laws of Delaware applicable to the matters addressed herein are
identical to the laws of the State of Texas.

     This opinion is provided solely for your benefit and the respective
successors and assigns of each of you and may not be relied upon by, or
disclosed to, any other persons.

                               Very truly yours,


                               /s/ Randolph W. Bryant

                                                                      SCHEDULE 1


     1.  Electrical Associates of Dallas, Inc. ("EAD") is not in good standing
         with the Texas Comptroller of Public Accounts. The Company has not been
         able to determine the reason for this status, but it believes that
         Electrical Associates of Dallas probably owes some amount of interest
         to the State of Texas concerning an amended tax return filed as a
         result of a federal audit.

     2.  Costner Brothers, Inc. is not in good standing with the State of South
         Carolina because of the alleged failure to file a required tax return.
         The South Carolina tax authorities have caused dissolution papers to be
         filed in that state. Representatives of the Company have discussed this
         matter with the South Carolina tax authorities, who were under the
         erroneous belief that a return was required for the tax period ending
         February 28, 1999. Although this situation was due to a mistake by the
         South Carolina tax authorities, the proper authorities cannot correct
         the mistake immediately, and the Company does not expect to be able to
         obtain a good standing certificate for Costner Brothers, Inc. until
         sometime in March 2000.

     3.  Four subsidiaries of the Company incorporated in Maryland (Commercial
         Air Holding Company, Commercial Air, Power & Cable, Inc., Masters, Inc.
         and Vantage Mechanical Contractors, Inc.) have apparently failed to
         file required personal property tax returns in that jurisdiction and
         therefor are not in good standing in that state.

 To the Administrative Agent and each
 of the Banks from time to time party to the
 Credit Agreement referred to below


 Ladies and Gentlemen:

 Pursuant to an Agreement and Plan of Merger dated as of November 2, 1999, as
 amended (the "Merger Agreement"), between Croup Maintenance America Corp., a
 Texas corporation (the "Texas Company" or the "Surviving Corporation") and
 Building One Services Corporation, a Delaware corporation (the "Delaware
 Company"), the Delaware Company will merge with and into the Texas Company and
 the separate corporate existence of the Delaware Company shall thereupon cease,
 with the Texas Company being the surviving corporation of the merger (the
 "Merger"). In connection with the transactions contemplated by the Merger
 Agreement, the Surviving Corporation is entering into a Credit Agreement (the
 "Credit Agreement") dated as of the Closing Date among the Surviving
 Corporation, the subsidiaries of the Surviving Corporation listed on the
 signature pages thereto, the banks and other financial institutions listed on
 the signature pages thereto under the caption "Banks", Chase Bank of Texas,
 National Association, individually as a Bank and as Syndication Agent, First
 Union National Bank, individually as a Bank and as Documentation Agent, and
 Bank of America, NA., individually as a Bank and as Administrative Agent for
 the other Banks. Defined terms used herein and not otherwise defined shall have
 the meanings ascribed to such term in the Merger Agreement.

 We have acted as special counsel to the Delaware Company in connection with the
 Merger and in that connection you have requested this opinion.

 In connection with this opinion, we have examined copies of the Merger
 Agreement and following documents (collectively referred to herein as "Loan
 Documents"):

     (i)   a counterpart of the Credit Agreement executed by the Surviving
           Corporation;

     (ii)  the form of Revolving Note attached as Exhibit 2.02(a-1) to the
           Credit Agreement;

     (iii) the form of Swingline Note attached as Exhibit 2.02(a-2) to the
           Credit Agreement;

     (iv)  the form of Tranche A Term Note attached as Exhibit 2.02(b) to the
           Credit Agreement;

     (v)   the form of Tranche B Term Note attached as Exhibit 2.02(c) to the
           Credit Agreement;

     (vi)  the Security Agreement dated as of February 22, 2000, executed by the
           Surviving Corporation and the subsidiaries of the Surviving
           Corporation party thereto; and

     (vii) the Pledge Agreement dated as of February 22, 2000, executed by the
           Surviving Corporation and the subsidiaries of the Surviving
           Corporation party thereto.

We have also examined originals or copies, certified or otherwise authenticated
to our satisfaction, of such records, certificates and documents as were deemed
relevant and necessaryin our judgment to render the opinions expressed below. We
also have examined and relied upon such other documents, instruments and
certificates of public officials and made such other investigations of fact and
law as we have deemed necessary.

We have assumed the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such latter documents.

As to certain matters of fact material to this opinion, we have, where such
facts were not independently known to us, relied with your consent upon the
representations and warranties made by the Delaware Company in the Merger
Agreement, upon the representations and warranties of the Texas Company in the
Credit Agreement and upon representations and warranties contained in
certificates of officers of the Delaware Company and the Texas Company.

Based upon the foregoing, and subject to the qualifications, assumptions and
other limitations stated herein, it is our opinion that:

The execution and delivery by the Delaware Company of the Merger Agreement and
the other documents and agreements to which it is a party that are contemplated
thereby do not and the consummation of the transactions contemplated thereunder
and under the Loan Documents
<PAGE>

To the Administrative Agent and each of the Banks
from time to time party to the Credit Agreement

will not (a) violate or constitute a default under the Indenture dated April
30, 1999, by and among the Delaware Company, as Issuer, the Guarantors named
therein and IBJ Whitehall Bank 8t Trust Company, as Trustee, related to the
Delaware Company's 10 1/2% Senior Subordinated Notes due 2009 (the "Indenture").
In particular, the Merger and the consummation of the other transactions
contemplated thereby will not constitute a "Change of Control" as such term is
defined in the Indenture.

The opinions expressed in the foregoing paragraph (the "Opinion Paragraph") are
subject in all respects to the following further qualifications, assumptions and
other limitations:

          a.  We express no opinion as to compliance by the Surviving
Corporation, upon consummation of the Merger and the other transactions
contemplated by the Merger Agreement and by the Loan Documents, of the covenants
set forth in Article four (other than Sections 4.04 and 4.15) of the Indenture.

          b.  With respect to our opinion set out above in the Opinion Paragraph
as it relates to Section 4.04 of the Indenture, we have relied op an officer's
certificate from each of the Delaware Company and the Texas Company, copies of
which are attached hereto, that (1) with respect to the Delaware Company prior
to the Merger, no Default or Event of Default (as defined in the Indenture) has
occurred and is continuing on the date of the Closing, (2) with respect to the
Surviving Corporation following the Merger, no Default or Event of Default will
occur as a consequence of the incurrence of Indebtedness (as defined in the
Indenture) in connection with the consummation of the transactions contemplated
by the Loan Documents, and (3) after giving effect to the incurrence of
Indebtedness (as defined in the Indenture) on the date of Closing in connection
with the transactions contemplated by the Merger Agreement and the Loan
Documents, the Consolidated Fixed Charge Coverage Ratio (as defined in the
Indenture) of the Surviving Corporation will be GREATER THAN 2.25 TO 1.0.

          c.  With respect to our opinion set out above in the Opinion Paragraph
as it relates to or is dependent upon Article Five of the Indenture:

              (i)  in respect of the conclusions called for under clause
          (a)(i)(2)(x) of Section 5.01 therein, we have assumed that the
          Surviving Corporation is a corporation organized and validly existing
          under the laws of the State of Texas;

              (ii) in respect of the matters required under clause (a)(i)(2)(y)
          of Section 5.01 of the Indenture, we have assumed that a supplemental
          indenture,
<PAGE>

To the Administrative Agent and each of the Banks
from time to time party to the Credit Agreement
February 22, 2000
Page 4


          in the form contemplated by such clause, has been duly authorized,
          executed and delivered by the Surviving Corporation;

               (iii) we have assumed the satisfaction of the conditions set
          forth in clauses (a)(ii) and (a)(iii) of Section 5.01 of the
          Indenture; and

               (iv)  based on the officer's certificate and opinion of counsel
          contemplated by clause (a)(iv) of Section 5.01 of the Indenture,
          copies of which are attached hereto, we have assumed the satisfaction
          of the condition set forth in such clause.

          d.   We have based our opinion set forth in the last sentence of the
Opinion Paragraph above on the assumption that the term "Affiliate" as used in
the indenture has the same meaning as such term has been defined and interpreted
under Rule 405 of the Securities Act of 1933, as amended.

The opinions expressed herein are limited to matters governed by the laws of the
Commonwealth of Pennsylvania, the State of New York and the Delaware General
Corporation Law and the federal laws of the United States of America. To the
extent that any opinion herein relates to matters governed by any laws other
than the laws to which the opinions expressed herein are limited, we have
assumed that such laws are the same as the laws of the Commonwealth of
Pennsylvania in all relevant respects.

This opinion letter is furnished solely for your benefit in connection with
matters relating to the Credit Agreement and may not be used or relied upon by
any other person or for any other purpose without our prior written consent.
This opinion is given as of the date hereof and we have no obligation to advise
you of any change after the date hereof pertaining to any matter referred to
herein.



Very truly yours,

Re: Building One Services Corporation 10 1/2% Senior Subordinated Notes Due 2009


Ladies and Gentlemen:

and Group Maintenance America Corp., a Texas corporation ("GroupMac"), pursuant
to the Agreement and Plan of Merger, effective February 22, 2000, whereby the

forth in the Indenture, dated as of April 30, 1999, as supplemented from time to
time, among the Company, as issuer, the Guarantors named therein and the Trustee
(the "Indenture") in relation to the issuance by the Company of up to
$400,000,000 of the Company's 10 1/2% Senior Subordinated Notes due 2009. This
opinion is furnished to you pursuant to Sections 5.01 and 13.04 of the

In connection with the rendering of this opinion, (1) I have read and am
familiar with the covenants and conditions of the Indenture relating to delivery
of an opinion of counsel with respect to the Merger and in respect to the
execution and delivery of the Supplemental Indenture wherein GroupMac shall
assume the obligations of the Company under the Indenture and that such Merger
and Supplemental Indenture comply with the applicable provisions of the
Indenture and that all conditions precedent in the Indenture relating to such
transactions have been satisfied; (2) I have reviewed and examined various
records of the Company and made an investigation of the conditions or covenants
in the Indenture relating to the Merger and the Supplemental Indenture; and (3)
I have made such examinations and investigations as are necessary to enable me
to express an informed opinion as to the matters set forth herein.

Based upon the foregoing, it is my opinion that the Merger and Supplemental
Indenture comply with the provisions of the Indenture and that all conditions
precedent, if any, provided for in the Indenture relating to the Merger have
been met.

This opinion is limited to the general corporate laws of the State of Delaware
and I do not express any opinion concerning any law other than the general
corporate laws of the State of Delaware and the federal laws of the United

Ladies and Gentlemen:


     In connection with the opinions to be delivered regarding the material
federal income tax consequences of the proposed merger (the "Merger") between
Group Maintenance America Corp., a Texas corporation (the "Texas Company"), and
Building One Services Corporation, a Delaware corporation (the "Delaware
Company") pursuant to the Agreement and Plan of Merger, as amended (the
"Agreement"), dated as of November 2, 1999 between the Texas Company and the
Delaware Company, the undersigned officer of the Delaware Company hereby
certifies and represents as to the Delaware Company that the facts relating to
the Agreement and as described in the Joint Proxy Statement/Prospectus of the
Texas Company and the Delaware Company (the "Joint Proxy Statement") included in
the registration statement of the Texas Company (the "Registration Statement")
dated December 27, 1999 are true, correct and complete in all respects as of the
date hereof and will be true, correct and complete in all respects at the
effective time of the Merger and that:

     1.  The facts relating to the contemplated merger of the Delaware Company
with and into the Texas Company (the "Merger") as described in the Joint Proxy
Statement and in Section 1 of the Agreement are true, accurate and complete in
all material respects insofar as they relate to the Delaware Company and/or any
person related to the Delaware Company.

     2.  The Merger will be consummated in accordance with the terms of the
Agreement and none of the material conditions to the Delaware Company's
performance of its obligations under the Agreement will be waived or modified
and the exchange of Preferred Stock will be
<PAGE>

consummated in accordance with the Subscription and Exchange Agreement dated
November 2, 1999 between the Texas Company and BOSS II, LLC.

     3.  The fair market value of the Texas Company stock and other
consideration received by each Delaware Company shareholder will be
approximately equal to the fair market value of the Delaware Company stock
surrendered in the exchange.

     4.  The liabilities of the Delaware Company assumed by the Texas Company
and the liabilities to which the transferred assets of the Delaware Company are
subject were not incurred by the Delaware Company in connection with the Merger.

     5.  Except as set forth in Sections 7.4 and 5.10 of the Agreement, The
Texas Company, the Delaware Company, and the stockholders of the Delaware
Company will pay their respective expenses, if any, incurred in connection with
the transaction.

     6.  There is no intercorporate indebtedness existing between the Delaware
Company and the Texas Company that was issued, acquired, or will be settled at
a discount.

     7.  The Delaware Company is not an investment company as defined in section
368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code.

     8.  The Delaware Company is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of section 368(a)(3)(A) of the
Internal Revenue Code.

     9.  The fair market value of the assets of the Delaware Company transferred
to the Texas Company will equal or exceed the sum of the liabilities assumed by
the Texas Company plus the amount of liabilities, if any, to which the
transferred assets are subject.

    10.  The payment of cash in lieu of fractional shares of Texas Company stock
is solely for the purpose of avoiding the expense and inconvenience to the Texas
Company of issuing fractional shares and does not represent separately
bargained-for consideration. The total cash consideration that will be paid in
the transaction to the Delaware Company stockholders instead of issuing
fractional shares of Texas Company stock will not exceed one percent of the
total consideration that will be issued in the transaction to the Delaware
Company stockholders in exchange for their shares of Delaware Company stock. The
fractional share interests of each Delaware Company stockholder will be
aggregated, and no Delaware Company stockholder will receive cash in an amount
greater to or greater than the value of one full share of Texas Company stock.

    11.  None of the compensation received by any stockholder-employees of the
Delaware Company will be separate consideration for, or allocable to, any of
their shares of Delaware Company stock; none of the shares of Texas Company
stock received by any such stockholder-employees will be separate
consideration for, or allocable to, any employment
<PAGE>

agreement; and the compensation paid to any such stockholder-employees will be
for services actually rendered and will be commensurate with amounts paid to
third parties bargaining at arm's-length for similar services.

    12.  The ratio of exchange of Delaware Company stock for Texas Company stock
was agreed upon as the result of arm's length negotiations between the
respective managements of the Texas Company and the Delaware Company.


    13.  The Delaware Company and its subsidiaries will not take, and
the Delaware Company is not aware of any plan or intention of Delaware Company
stockholders to take any position on any federal, state, or local income or
franchise tax return, or take any other tax reporting position, that is
inconsistent with the treatment of the Merger as a reorganization within the
meaning of Section 368(a) of the Code unless otherwise required by a final
determination under Section 1313(a)(1) of the Code or by comparable provisions
or state or local income or franchise tax law.

    14.  Neither the Delaware Company nor any of its subsidiaries has
constituted either a "distributing corporation" or a "controlled corporation"
(within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of
stock qualified for tax free treatment under Section 355 of the Code (a) in the
two years prior to the date of the Agreement or (b) in a distribution that could
otherwise constitute part of a "plan" or "series of related transactions"
(within the meaning of Section 355(e) of the Code) in conjunction with the
Merger.

     We understand that Bracewell & Patterson, L.L.P. and Morgan, Lewis &
Bockius LLP will rely on this letter in rendering their respective opinions as
to the material federal income tax consequences of the Merger and we will
promptly and timely inform them if, after signing this letter, we have reason to

Statement or the Registration Statement or any of the representations made in
this letter are untrue, incorrect or incomplete in any respect.

Dear Ladies and Gentlemen:

Pursuant to an Agreement and Plan of Merger dated as of November 2, 1999 (the
"Agreement") between Group Maintenance America Corp., a Texas corporation (the
"Texas Company") and Building One Services Corporation, a Delaware corporation
(the "Delaware Company" and together with the Texas Company, the "Companies"),
the Delaware Company will merge with and into the Texas Company and the separate
corporate existence of the Delaware Company shall thereupon cease, with the
Texas Company being the surviving corporation of the merger (the "Merger").
Defined terms used herein and not otherwise defined shall have the meanings
ascribed to such term in the Agreement.

We have acted as counsel to the Delaware Company in connection with the Merger
and in that connection you have requested our opinion regarding the material
federal income tax consequences of the Merger to holders of shares of the Texas
and Delaware Companies' Common Stock and to the Companies. Our opinion only
addresses the federal income tax consequences of the Merger to holders of
Delaware Company Common Stock that hold their shares as capital assets and does
not address all aspects of federal income taxation that may be important to such
holders in light of their particular circumstances. Further, our opinion does
not address all aspects of federal income taxation that may be applicable to
certain holders subject to special rules, such as: (i) holders who are not
United States persons; (ii) financial institutions; (iii) tax-exempt
organizations; (iv) insurance companies; (v) dealers or brokers in securities;
(vi) holders who held their Delaware Company or Texas Company stock as part of a
hedge, appreciated financial position, straddle, or conversion transaction; or
(vii) holders who acquired their Delaware Company or Texas Company stock
pursuant to the exercise of employee stock options or otherwise as compensation.
In rendering our opinion, we have examined the Agreement, the registration
Statement of the Texas Company ("the Registration Statement"), the joint proxy
statement/prospectus of the Companies ("the Proxy Statement"), certain factual
representations contained in Officer's Certificates of the Delaware Company and
the Texas Company dated as of today's date which have been delivered to us for
purposes of this opinion (the "Officer's Certificates") and such other documents
and corporate records as we have deemed necessary or appropriate for purposes of
this opinion. In addition, we have

assumed: (i) the Merger will be consummated in the manner contemplated in the
Registration Statement and the Proxy Statement and in accordance with the
provisions of the Agreement, (ii) the statements concerning the Merger and
related transactions set forth in the Registration Statement and the Proxy
Statement are accurate and complete, (iii) the representations in the Officer's
Certificates dated as of today's date are accurate and complete and will be
accurate and complete as of the effective time of the merger, and (iv) any
representations in the Officer's Certificates that are qualified by the phrases
"to the best knowledge," "has no knowledge," or similar phrases are, in each
case, correct without such qualification.

      Under current law, and on the basis and subject to (i) the accuracy of
the statements and representations contained in the materials referred to above
assumptions and (ii) our considerations of such other matters as we have deemed
necessary, our opinion of the material federal income tax consequences to
holders of Texas and Delaware Company Common Stock and the Companies is as
follows:

      (A)  The merger of the Delaware Company with and into the Texas Company
will be treated for federal income tax purposes as a reorganization within the
meaning of Section  368(a) of the Internal Revenue Code of 1986, as amended,
(the "Code"), and the Texas Company and the Delaware Company will each be a
party to the reorganization within the meaning of Section 368(b) of the Code;

     (B)  no gain or loss will be recognized for federal income tax purposes by
the Texas Company, the Delaware Company, holders of Texas Company Common Stock,
or holders of Delaware Company Common Stock as a result of the Merger, except
with respect to cash received in lieu of fractional shares by holders of
Delaware Company Common Stock and with respect to cash received by holders of
Texas Company Common Stock as a result of the exchange of their shares pursuant
to the Exchange Agreement.

     (C)  the aggregate tax basis of shares the Texas Company Common Stock
received by a holder of the Delaware Company Common Stock in the Merger
will be the same as such holder's aggregate tax basis of the Delaware Company
Common Stock surrendered in the Merger, reduced by any such tax basis allocable
to fractional shares of the Texas Company Common Stock for which cash is
received in lieu of such fractional share;

     (D)  the holding period of Texas Company Common Stock received by former
Delaware Company shareholders in the Merger will include the period during which
such shareholder held the Delaware Company Common Stock exchanged in the Merger
if such shareholder held such Delaware Company Common Stock as a capital asset;
and

     (E) a holder of Delaware Company Common Stock who receives cash in lieu of
fractional shares of the Texas Company Common Stock in the Merger will recognize
gain or loss measured by the difference between the amount of cash received and
the portion of such holder's aggregate tax basis allocable to such fractional
share. Any such gain or loss generally will be capital gain or loss if the
Delaware Company Common Stock surrendered in the Merger was held as a capital
asset, and will be long-term capital gain or loss if such Delaware Company
Common Stock has been held for more than one year as of the date of the closing
of the Merger.

You have not requested, and we do not express, an opinion concerning any other
tax consequences of the Merger.

Our opinion expresses our views only as to the U.S. federal income tax laws in
effect as of the date hereof. It represents our best legal judgment as to the
matters addressed in our opinion, but is not binding on the Internal Revenue
Service or the courts. Accordingly, no assurance can be given that our opinion
will be respected by the Internal Revenue Service or, if contested, would be
sustained by a court. Furthermore, the authorities upon which we rely are
subject to change either prospectively or retroactively, and any change in such
authorities or variation or difference in the facts from those on which we rely
and assume as correct, as set forth above, might affect the conclusion stated.
This opinion is expressed as of the date hereof, and we are under no obligation
to supplement or revise our opinion to reflect any changes (including changes
that have retroactive effect) (i) in applicable law, or (ii) in any information,
document, corporate record, covenant, statement, representation, or assumption
stated therein that becomes untrue or incorrect.

Our opinion is not to be used, circulated, quoted or otherwise referred to for
any purpose without our express written permission.

Very truly yours,

Credit Agreement referred to below



Ladies and Gentlemen:



I am general counsel to Building One Services Corporation, a Delaware
corporation ("BOSS"), BOSS and Group Maintenance America, Corp., a Texas
corporation (the "Company") are parties to an Agreement and Plan of Merger (as
amended, the "Merger Agreement") dated as of November 2, 1999, pursuant to which
BOSS will be merged with and into the Company with the Company as the surviving
corporation. In connection with the transactions contemplated by the Merger
Agreement, the Company will enter into a Credit Agreement (the "Credit
Agreement") dated as of February 22, 2000 among the Company, the Subsidiaries of
the Company listed on the signature pages thereto (including the subsidiaries of
BOSS (the "BOSS Subsidiaries," and, together with BOSS, the "BOSS Parties"), the
banks and other financial institutions listed on the signature pages thereto
under the caption "Banks", Chase Bank of Texas, National Association,
individually as a Bank and as Syndication Agent, First Union National Bank,

opinion is delivered to you pursuant to Section 4.01(h) of the Credit Agreement.
Capitalized terms used herein but not defined herein shall have the meanings set
forth in the Credit Agreement.

In acting as counsel for the BOSS Parties, I have examined originals or
counterparts of the Merger Agreement, the Credit Agreement and the transaction
documents contemplated thereby (collectively, the "Transaction Documents"). In
addition, I have examined originals or copies, certified or otherwise
authenticated to my satisfaction, of such records, certificates and documents as
were deemed relevant and necessary in my judgment to render the opinions
expressed below. I also have examined and relied upon such other documents,
instruments and certificates of public officials and made such other
investigations of fact and law as I have deemed necessary.

I have assumed the genuineness of all signatures, the authenticity of all
documents submitted to me as originals, the conformity to original documents of
all documents submitted to me as certified or photostatic copies and the
authenticity of the originals of such latter documents.

As to certain matters of fact material to this opinion, I have, where such facts
were not independently known to me, relied with your consent upon the
representations and warranties

made by the BOSS Parties in the Transaction Documents and in certificates of
officers of the BOSS Parties.

Based upon the foregoing, and subject to the qualifications and limitations
stated herein, it is my opinion that:

     1. Except as set forth on Exhibit A hereto, each of the BOSS Parties is
validly existing and in good standing under the laws of its state of
incorporation or organization.

     2. The execution, delivery and performance by each of the BOSS Parties of
the Transaction Documents to which it is a party are within the power and
authority of such BOSS Party, and have been duly authorized by all necessary
action on the part of such BOSS Party.

     3. Each Merger Transaction Document to which a BOSS Party is a party has
been duly executed and delivered by such BOSS Party.

     4. The execution and delivery of the Transaction Documents by the BOSS
Parties does not and the consummation of the transactions contemplated
thereunder will not (a) conflict with, violate, result in a breach of or require
any consent under, any provision of the Articles or Certificate of Incorporation
or organization, By-laws or equivalent organizational document of any ofthe BOSS
Parties or (b) to my knowledge, violate or constitute a default under any
agreement, document or instrument to which any of the BOSS Parties is a party or
by which any of it or its properties are bound except for such violations as
would not have a Material Adverse Effect.

     5. To the best of my knowledge, there is no litigation, investigation or
administrative proceeding of or before any court, arbitrator or governmental
authority pending or threatened against any BOSS Party with respect to the
Transaction Documents.

I am a member of the bar of the Commonwealth of Pennsylvania. The opinions
expressed herein are limited to matters governed by the laws of the Commonwealth
of Pennsylvania, the

     Credit Agreement Schedule 6.03 - Insurance Policies

Part B

BOSC maintains a comprehensive property and casualty insurance program designed
to protect it and all of its subsidiary companies from such losses as usually
insured by companies in similar industries. These insurance coverages include
Workers Compensation insurance, which provides statutory benefits owed injured
workers under the various state workers compensation laws; Comprehensive General
Liability coverage, Comprehensive Automobile Liability coverage and Employers
Liability coverage, each subject to a $100,000,000 umbrella limit; Contractor's
Pollution Liability and Professional Liability, subject to a combined
$25,000,000 limit; and Crime Insurance (including Fidelity) subject to a
$5,000,000 limit.

The Insurance program also includes coverage for loss to physical property and
equipment owned by BOSC or its subsidiaries, or non-owned property and equipment
which BOSC or its subsidiaries are required to insure by way of a lease, rental
agreement or other similar contract.  Such coverage is subject to the following
catastrophic loss limits:  $50,000,000 Buildings; $15,000,000 Contents;
$12,000,000 Extra Expense; $20,000,000 Contractor's Equipment; and $10,000,000
Equipment & Materials being installed at a project site.

The above coverages and limits are subject to actual policy wording,
deductibles, limitations, coverage extensions and exclusions, all of which are
no more restrictive than those of similar companies in the industry.

performance by the Company of all of its obligations as of such date; it being
understood that if the Company has not fully paid and performed all of its
obligations as of such date, the Company's obligations under this Section 3
shall survive until such obligations have been satisfied) and the date on which
Sections 15(a) and 15(b) hereof have ceased to have any effect, if the Investor
concludes, either as a result of a notice delivered by the Company pursuant to
Section 3(g), or otherwise, that an Event of Non-Compliance has occurred or is
reasonably likely to occur, the Investor shall deliver a notice to the Company
to such effect. If an Event of Non-Compliance shall occur and shall be
continuing at the end of the one week period following delivery by the Investor
of the notice referred to in the preceding sentence (each, a "Trigger Event"),
the Investor shall have the special right to designate that number of
individuals to the Board that, when combined with the Preferred Directors, will
constitute a majority of the Board. The Company agrees to take all necessary and
desirable action within its control in connection with and in furtherance of the
execution of such special right. Such special right shall continue until such
time as there is no longer a Trigger Event in existence, at which time such
special right shall terminate, subject to revesting upon the subsequent
occurrence and continuation of any Trigger Event. After designees of the
Investor represent a majority of the Board, the directors of the Company shall
use commercially reasonable efforts promptly to cure the condition that
constituted the Event of Non-Compliance. After the expiration of such Trigger
Event, the term of office of such newly elected directors shall automatically
cease and the number of directors constituting the entire Board shall be reduced
accordingly.

                                      -10-
<PAGE>

        (i) Whenever the Investor shall have the right to designate one or more
directors of the Board pursuant to this Section 3, the Company shall, to the
extent permitted by applicable law (a) increase as required the number of
directors constituting the entire Board, (b) fill the vacancies created by such
expansion with designees who are approved by the Company, which approval will
not be unreasonably withheld and (c) submit the name of each such designee to
the shareholders of the Company (together with a recommendation of his or her
election) at each meeting of the shareholders at which directors are elected and
which is held during the period which the Investor is entitled to designate one
or more directors. The Company shall take such actions as shall be within its
control and reasonably necessary to effectuate the provisions of this Section 3,
including, if required, the calling of a special or annual meeting of the
shareholders of the Company to fill vacancies created by any increase in the
size of the entire Board.

        (j) Notwithstanding any provision of this Agreement to the contrary, the
rights of the Investor to designate Board members pursuant to this Section 3
shall in no event be operative at any time when the holders of the Convertible
Preferred Stock shall have rights to elect directors pursuant to the Statement
of Designations.

SECTION 4.  INFORMATION RIGHTS; COVENANTS.

        (a)  Access to Records.

        The Company shall, and shall cause each Subsidiary to, afford to the
Investor, the Affiliates of the Investor and each of their respective officers,
employees, advisors, counsel and other authorized representatives (collectively
with the Affiliates of the Investor, the "Representatives"), during normal
business hours, at their expense, reasonable access, upon reasonable advance
notice, to all of the books, records and properties of the Company and such
Subsidiary and all officers and employees of the Company and such Subsidiary.
The Investor shall use its best efforts to maintain the confidentiality of any
information designated by the Company as confidential or proprietary; provided,
however, that the foregoing shall in no way limit or otherwise restrict the
ability of the Investor or any of its Representatives to disclose any such
information concerning the Company and each Subsidiary which it may be required
to disclose (i) to its partners or limited partners to the extent required to
satisfy its fiduciary obligations to such Persons, provided such Persons agree
in writing to be bound by the provisions of this Section, or (ii) otherwise
pursuant to or as required by law.

        (b)  Financial Reports.

        The Company shall furnish the Investor with the following:

(i)  Monthly Reports.  As soon as available, but not later than 30 days after
     the end of each fiscal month, a consolidated balance sheet of the Company
     as of the end of such period and consolidated statements of income of the
     Company for such period and for the period commencing at the end of the
     previous fiscal year and ending with the end of such period, setting forth
     in each case in comparative form the corresponding figures for the
     corresponding period of the preceding fiscal year, and including
     comparisons for income statements to the budget or business plan all
     prepared in

                                      -11-

      the end of each quarterly accounting period, (A) a consolidated balance
      sheet of the Company as of the end of such period and consolidated
      statements of income and cash flows for such quarterly accounting period
      and/or for the period commencing at the end of the previous fiscal year
      and ending with the end of such period, setting forth in each case in
      comparative form the corresponding figures for the corresponding period of
      the preceding fiscal year, and including comparisons to the budget or
      business plan for the income statement only, all prepared in accordance
      with GAAP consistently applied and (B) a report by management of the
      Company in a format consistent with Form 10-Q of the operating and

      balance sheet as of the last day thereof, each prepared in accordance with
      generally accepted accounting principles, consistently applied, and
      accompanied by the report of a "Big 5" firm of independent certified
      public accountants selected by the Board (the "Accountants"). The Company
      and its Subsidiaries shall maintain a system of accounting sufficient to
      enable its Accountants to render the report referred to in this Section 4;
      and

(iv)  Miscellaneous. Promptly upon becoming available, the Company shall provide
      to the Investor:

        (A)  copies of all financial statements, reports, press releases,
             notices, proxy statements and other documents sent by the Company
             or its Subsidiaries to its investors generally or released to the
             public and copies of all regular and periodic reports, if any,
             filed by the Company or its Subsidiaries with the Securities and
             Exchange Commission, any securities exchange or the NYSE;

        (B)  notification in writing of any litigation or governmental
             proceeding in which it or any of its Subsidiaries is involved and

             affect the Company or any of its material Subsidiaries;

        (C)  notification in writing of the existence of any default under any
             material agreement or instrument to which the Company or any of its
             Subsidiaries is a party or by which any of their assets are bound;

        (D)  upon request, copies of all reports prepared for or delivered to
             the management of the Company or its Subsidiaries by its
             accountants;

                                      -12-
<PAGE>

        (E)  upon request, any other routinely collected financial or other
             information available to management of the Company or its
             subsidiaries (including, without limitation, routinely collected
             statistical data); and

        (F)  The provisions of this Section 4 shall terminate upon the earlier
             to occur of the twelfth anniversary of the Closing Date and the
             date on which the Investor shall no longer be entitled to elect any
             directors pursuant to Section 3(a) of this Agreement.

SECTION 5.  DEMAND REGISTRATION.

        (a) If the Company shall be requested by holders of at least 20% of the
total number of outstanding Restricted Shares (assuming conversion of all shares
of Convertible Preferred Stock) to effect a registration under the Securities
Act of all or a portion of Restricted Shares with an aggregate Fair Market Value
as of the date of such request equal to at least $25,000,000, or, if the
Restricted Shares have an aggregate Fair Market Value of less than $25,000,000,
all of the remaining Restricted Shares, in accordance with this Section, then
the Company shall promptly give written notice of such proposed registration to
all holders of Restricted Shares and shall offer to include in such proposed
registration any Restricted Shares requested to be included in such proposed
registration by such holders who respond in writing to the Company's notice
within 15 days after delivery of such notice (which response shall specify the
number of Restricted Shares proposed to be included in such registration and the
intended method of distribution, which may be pursuant to a shelf registration).
If a registration pursuant to Section 7 hereof is available, the holders of
Restricted Shares shall utilize such registration instead of making a request
pursuant to this Section 5, unless the holders of Restricted Shares reasonably
determine that it is advantageous to such holders of Restricted Shares to make a
request under this Section 5. The Company shall promptly use its best efforts to
effect such registration on an appropriate form under the Securities Act of the
Restricted Shares which the Company has been so requested to register; provided,
however, that the Company shall not be obligated to effect any registration
under the Securities Act except in accordance with the following provisions:

(i)  the Company shall not be obligated to file more than four registration
     statements in total pursuant to this Section, subject to paragraph (c)
     below;

(ii) the Company shall not be obligated to file any registration statement
     during any period in which (A) any other registration statement (other than
     on Form S-4 or Form S-8 promulgated under the Securities Act or any
     successor forms thereto) pursuant to which Primary Shares are to be or were
     sold has been filed and not withdrawn or has been declared effective within
     the prior 90 days or (B) the Company has determined in good faith that the
     filing of a registration statement would require the disclosure of material
     information that the Company has a bona fide business purpose for
     preserving as confidential, such filing to be delayed until the date which
     is 90 days after such request for registration pursuant to this Section
     5(a); provided that the Company may only so delay the filing or
     effectiveness of a registration statement pursuant to this Section
     5(a)(ii)(B) on one occasion during any twelve-month period; and

                                      -13-
<PAGE>

(iii) with respect to the registration pursuant to this Section, the Company may
      include in such registration any Primary Shares or Other Shares; provided,
      however, that if the managing underwriter advises the Company in writing
      that the inclusion of all Restricted Shares, Primary Shares and Other
      Shares proposed to be included in such registration would interfere with
      the successful marketing (including pricing) of all such securities, then
      the number of Restricted Shares, Primary Shares and Other Shares proposed
      to be included in such registration shall be included in the following
      order:

        (A)  First, the Restricted Shares, pro rata based upon the number of
             Restricted Shares owned by each holder at the time of such
             registration;

        (B)  Second, the Primary Shares; and

        (C)  Third, the Other Shares.

        (b) The holders of Restricted Shares requesting a registration pursuant
to this Section may, in the notice delivered pursuant to paragraph (a) above,
elect that such registration cover an underwritten offering. Upon such election,
such holders shall select one or more nationally recognized firms of investment
banks to act as the managing underwriters and shall select any additional
investment banks to be used in connection with such offering, provided that such
investment banks must be reasonably satisfactory to the Company. The Company
shall, together with all holders proposing to sell Restricted Shares in such
offering, enter into a customary underwriting agreement with such underwriters.

        (c) A requested registration under this Section may be rescinded by
written notice to the Company by the Persons holding a majority of the
Restricted Shares to be included in such registration with the following
consequences:

(i)   If such registration statement is rescinded prior to the filing date, such
      rescinded registration shall not count as a registration statement
      initiated pursuant to this Section for purposes of paragraph (a) above;

(ii)  If such registration statement is rescinded after the filing date but
      prior to its effective date, such rescinded registration shall not count
      as a registration statement initiated pursuant to this Section for
      purposes of paragraph (a) above if the participating holders (x) have
      reimbursed the Company for all out-of-pocket expenses incurred by the
      Company in connection with such rescinded registration or (y) (1)
      reasonably believed that the registration statement contained an untrue
      statement of material fact or omitted to state a material fact required to
      be stated therein or necessary to make the statements made therein not
      misleading, (2) notified the Company of such fact and requested that the
      Company correct such alleged misstatement or omission and (3) the Company
      has refused to correct such alleged misstatement or omission; and

(iii) A registration that becomes effective shall not count as a registration
      statement initiated pursuant to this Section for purposes of paragraph (a)
      above unless the participating holders are able to sell at least 80% of
      the Restricted Shares sought to be included in such registration
      statement.

SECTION 6.  PIGGYBACK REGISTRATION.

          If at any time the Company proposes for any reason to register Primary
Shares or Other Shares under the Securities Act (other than on Form S-4 or Form
S-8 promulgated under the Securities Act or any successor forms thereto, it
shall promptly give written notice to the holders of Restricted Shares of its
intention to so register the Primary Shares or Other Shares and, upon the
written request, given within 15 days after delivery of any such notice by the
Company, of any holders of Restricted Shares to include in such registration
Restricted Shares held by such holders (which request shall specify the number
of Restricted Shares proposed to be included in such registration), the Company
shall use its best efforts to cause all such Restricted Shares to be included in
such registration on the same terms and conditions as the securities otherwise
being sold in such registration; provided, however, that if the managing
underwriter advises the Company that the inclusion of all Restricted Shares or
Other Shares proposed to be included in such registration would interfere with
the successful marketing (including pricing) of the Primary Shares proposed to
be registered by the Company, then the number of Primary Shares, Restricted
Shares and Other Shares proposed to be included in such registration shall be
included in the following order:

        (a)  first, the Primary Shares;

        (b) second, Other Shares entitled to registration pursuant to the
Registration Rights Agreements set forth on Annex A;

        (c) third, Restricted Shares, pro rata based upon the number of
Restricted Shares owned by each holder at the time of such registration; and

        (d) fourth, the Other Shares (other than those shares of Common Stock
which are not subject to any registration rights agreement), pro rata based upon
the number of shares of Common Stock (based upon Common Stock Equivalents) owned
by each such seller at the time of such registration.

SECTION 7.  S-3 REGISTRATIONS.

          If at any time (i) the Persons holding at least 20% of the total
number of outstanding Restricted Shares (assuming conversion of all shares of
Convertible Preferred Stock) request that the Company file a registration
statement on Form S-3 or any successor thereto for a public offering of all or a
portion of Restricted Shares with an aggregate Fair Market Value as of the date
of such request equal to at least $25,000,000, or, if the aggregate Restricted
Shares have an aggregate Fair Market Value of less than $25,000,000, all of the
remaining Restricted Shares and (ii) the Company is a registrant entitled to use
Form S-3 or any successor thereto to register such shares, then the Company
shall use its best efforts to register under the Securities Act on Form S-3 or
any successor thereto, for public sale in accordance with the method of
disposition specified in such notice, the number of shares of Restricted Shares
specified in such notice.  Whenever the Company is required by this Section 7 to
use its best efforts to effect the registration of Restricted Shares, each of
the procedures and requirements of Section 5 (including but not limited to the
requirement that the Company notify all holders of Restricted Shares from whom
notice has not been received and provide them with the opportunity to
participate in the

                                      -15-
<PAGE>

offering) shall apply to such registration. Notwithstanding anything to the
contrary contained herein, no request may be made under this Section 7 within
three months after the effective date of a registration statement filed by the
Company covering a firm commitment underwritten public offering in which the
holders of Restricted Shares shall have been entitled to join pursuant to
Section 5 or 6 in which there shall have been effectively registered all
Restricted Shares as to which registration shall have been requested. There is
no limitation on the number of registrations pursuant to this Section 7 that the
Company is obligated to effect.

SECTION 8.  EXPENSES.

          The Company shall bear the expense of any registrations effected
pursuant to Sections 5, 6 and 7 including, without limitation, all registration
and filing fees (including all expenses incident to filing with the NYSE), fees
and expenses of complying with securities and blue sky laws, printing expenses,
and fees and expenses of the Company's counsel and accountants, and the fees and
expenses of the Selling Holders' Counsel (as defined below), but excluding any
underwriters' or brokers' discounts or commissions, transfer taxes (to the
extent that such taxes are required by law to be paid by the Selling Holders)
and the fees of any counsel to any Selling Holder, other than the Selling
Holders' Counsel (it being understood that the fees and expenses of any
underwriter and such underwriter's counsel shall be the responsibility of such
underwriter).

SECTION 9.  PREPARATION AND FILING.

          If and whenever the Company is under an obligation pursuant to the
provisions of this Agreement to use its best efforts to effect the registration
of any Restricted Shares, the Company shall, as expeditiously as practicable:

(a)  with respect to a registration under Sections 5, 6 and 7, use its best
     efforts to cause a registration statement that registers such Restricted
     Shares to become and remain effective for a period of 180 days or until all
     of such Restricted Shares have been disposed of (if earlier);

(b)  furnish, at least five business days before filing a registration statement
     that registers such Restricted Shares, a prospectus relating thereto or any
     amendments or supplements relating to such a registration statement or
     prospectus, to each holder of Restricted Shares, to any counsel to any
     seller of Restricted Shares (the "Selling Holder") and to one counsel
     selected by the holders of a majority of such Restricted Shares (the
     "Selling Holders' Counsel"), copies of all such documents proposed to be
     filed (it being understood that such five-business-day period need not
     apply to successive drafts of the same document proposed to be filed so
     long as such successive drafts are supplied to such counsel in advance of
     the proposed filing by a period of time that is customary and reasonable
     under the circumstances);

(c)  prepare and file with the Commission such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     as may be necessary to keep such registration statement effective for at
     least the periods set forth in Section 9(a) or until all of such Restricted
     Shares have been disposed of (if earlier) and to comply with the

                                      -16-
<PAGE>

     provisions of the Securities Act with respect to the sale or other
     disposition of such Restricted Shares;

(d)  notify in writing any counsel to any Selling Holder and the Selling
     Holders' Counsel promptly (i) of the receipt by the Company of any
     notification with respect to any comments by the Commission with respect to
     such registration statement or prospectus or any amendment or supplement
     thereto or any request by the Commission for the amending or supplementing
     thereof or for additional information with respect thereto, (ii) of the
     receipt by the Company of any notification with respect to the issuance by
     the Commission of any stop order suspending the effectiveness of such
     registration statement or prospectus or any amendment or supplement thereto
     or the initiation or threatening of any proceeding for that purpose and
     (iii) of the receipt by the Company of any notification with respect to the
     suspension of the qualification of such Restricted Shares for sale in any
     jurisdiction or the initiation or threatening of any proceeding for such
     purposes;

(e)  use its best efforts to register or qualify such Restricted Shares under
     such other securities or blue sky laws of such jurisdictions as any seller
     of Restricted Shares reasonably requests and do any and all other acts and
     things which may be reasonably necessary or advisable to enable such seller
     of Restricted Shares to consummate the disposition in such jurisdictions of
     the Restricted Shares owned by such seller; provided, however, that the
     Company will not be required to qualify generally to do business, subject
     itself to general taxation or consent to general service of process in any
     jurisdiction where it would not otherwise be required so to do but for this
     paragraph (e);

(f)  furnish to each seller of such Restricted Shares such number of copies of a
     summary prospectus or other prospectus, including a preliminary prospectus,
     in conformity with the requirements of the Securities Act, and such other
     documents as such seller of Restricted Shares may reasonably request in
     order to facilitate the public sale or other disposition of such Restricted
     Shares;

(g)  use its best efforts to cause such Restricted Shares to be registered with
     or approved by such other governmental agencies or authorities as may be
     necessary by virtue of the business and operations of the Company to enable
     the seller or sellers thereof to consummate the disposition of such
     Restricted Shares;

(h)  notify on a timely basis each seller of such Restricted Shares at any time
     when a prospectus relating to such Restricted Shares is required to be
     delivered under the Securities Act within the appropriate period mentioned
     in paragraph (a) of this Section, of the happening of any event as a result
     of which the prospectus included in such registration statement, as then in
     effect, includes an untrue statement of a material fact or omits to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances then
     existing and, at the request of such seller, prepare and furnish to such
     seller a reasonable number of copies of a supplement to or an amendment of
     such prospectus as may be necessary so that, as thereafter delivered to the
     offerees of such shares, such prospectus shall not include an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing;

                                      -17-
<PAGE>

(i)  make available for inspection by any counsel to any Selling Holder and the
     Selling Holders' Counsel or any underwriter participating in any
     disposition pursuant to such registration statement and any attorney,
     accountant or other agent retained by any such underwriter (collectively,
     the "Inspectors"), all pertinent financial and other records, pertinent
     corporate documents and properties of the Company (collectively, the
     "Records"), as shall be reasonably necessary to enable them to exercise
     their due diligence responsibility, and cause the Company's officers,
     directors and employees to supply all information (together with the
     Records, the "Information") reasonably requested by any such Inspector in
     connection with such registration statement.  Any of the Information which
     the Company determines in good faith to be confidential, and of which
     determination the Inspectors are so notified, shall not be disclosed by the
     Inspectors unless (i) the disclosure of such Information is necessary to
     avoid or correct a misstatement or omission in the registration statement,
     (ii) the release of such Information is ordered pursuant to a subpoena or
     other order from a court of competent jurisdiction or (iii) such
     Information has been made generally available to the public.  The seller of
     Restricted Shares agrees that it will, upon learning that disclosure of
     such Information is sought in a court of competent jurisdiction, give
     notice to the Company and allow the Company, at the Company's expense, to
     undertake appropriate action to prevent disclosure of the Information
     deemed confidential;

(j)  in the case of an underwritten offering, use its best efforts to obtain
     from its independent certified public accountants "comfort" letters in
     customary form and at customary times and covering matters of the type
     customarily covered by comfort letters;

(k)  in the case of an underwritten offering, use its best efforts to obtain
     from its counsel an opinion or opinions in customary form;

(l)  provide a transfer agent and registrar (which may be the same entity and
     which may not be the Company) for such Restricted Shares;

(m)  issue to any underwriter to which any seller of Restricted Shares may sell
     shares in such offering certificates evidencing such Restricted Shares;
     provided, however, that the Company shall have the right to approve any
     such underwriter with such approval not to be unreasonably withheld;

(n)  list such Restricted Shares on any national securities exchange on which
     any shares of the Common Stock are listed or on NASDAQ if then included, or
     if the Common Stock is not listed on a national securities exchange, use
     its best efforts to qualify such Restricted Shares for inclusion on such
     national securities exchange or NASDAQ as the holders of a majority of such
     Restricted Shares shall request;

(o)  otherwise use its best efforts to comply with all applicable rules and
     regulations of the Commission and make available to its securityholders, as
     soon as reasonably practicable, earnings statements (which need not be
     audited) covering a period of 12 months beginning within three months after
     the effective date of the registration statement, which earnings statements
     shall satisfy the provisions of Section 11(a) of the Securities Act; and

                                      -18-
<PAGE>

(p)  use its best efforts to take all other steps necessary to effect the
     registration of such Restricted Shares contemplated hereby.


SECTION 10.  INDEMNIFICATION.

(a)  In connection with any registration of any Restricted Shares under the
     Securities Act pursuant to this Agreement, the Company shall indemnify and
     hold harmless the seller of such Restricted Shares, its officers and
     directors, each underwriter, broker or any other person acting on behalf of
     such seller and each other person, if any, who controls any of the
     foregoing persons within the meaning of the Securities Act against any
     losses, claims, damages or liabilities, joint or several, (or actions in
     respect thereof) to which any of the foregoing persons may become subject
     under the Securities Act or otherwise, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon an untrue statement or alleged untrue statement of a material
     fact contained in the registration statement under which such Restricted
     Shares were registered under the Securities Act, any preliminary prospectus
     or final prospectus contained therein or otherwise filed with the
     Commission, any amendment or supplement thereto or any document incident to
     registration or qualification of any Restricted Shares, or arise out of or
     are based upon the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, and shall reimburse such seller, such officer or
     director, such underwriter, such broker or such other person acting on
     behalf of such seller and each such controlling person for any legal or
     other expenses reasonably incurred by any of them in connection with
     investigating or defending any such loss, claim, damage, liability or
     action; provided, however, that the Company shall not be liable in any such
     case to the extent that any such loss, claim, damage, liability or action
     arises out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in said registration
     statement, preliminary prospectus, final prospectus, amendment, supplement
     or document incident to registration or qualification of any Restricted
     Shares in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such seller
     or underwriter specifically for use in the preparation thereof; provided,
     further, that with respect to any preliminary prospectus, the foregoing
     indemnity shall not inure to the benefit of (a) any underwriter or, in the
     case of a registration statement filed with respect to an offering which is
     not an underwritten offering, any Selling Holder, from whom the person
     asserting any losses, claims, damages and liabilities and judgments
     purchased Restricted Shares or (b) any person controlling such underwriter
     or Selling Holder, if (i) a copy of the prospectus (as then amended or
     supplemented if the Company shall have furnished any amendments or
     supplements thereto) was required by law to have been delivered by such
     underwriter or Selling Holder (as applicable), (ii) the prospectus had not
     been sent or given by or on behalf of such underwriter or Selling Holder
     (as applicable) to such person with or prior to a written confirmation of
     the sale of the Restricted Shares to such person, (iii) the prospectus (as
     so amended and supplemented) would have cured the defect giving rise to
     such loss, claim, damage, liability or judgment and (iv) such failure to
     deliver the prospectus (as so amended and supplemented) was not the result
     of noncompliance by the Company with Section 9(f) hereof.

(b)  In connection with any registration of Restricted Shares under the
     Securities Act pursuant to this Agreement, each seller of Restricted Shares
     shall indemnify and hold harmless (in the same manner and to the same
     extent as set forth in the preceding paragraph of

                                      -19-
<PAGE>

     this Section) the Company, each director of the Company, each officer of
     the Company, each underwriter, broker or other person acting on behalf of
     such seller, each person who controls any of the foregoing persons within
     the meaning of the Securities Act and each other seller of Restricted
     Shares under such registration statement with respect to any statement or
     omission from such registration statement, any preliminary prospectus or
     final prospectus contained therein or otherwise filed with the Commission,
     any amendment or supplement thereto or any document incident to
     registration or qualification of any Restricted Shares, if such statement
     or omission was made in reliance upon and in conformity with written
     information furnished to the Company or such underwriter through an
     instrument duly executed by such seller specifically for use in connection
     with the preparation of such registration statement, preliminary
     prospectus, final prospectus, amendment, supplement or document; provided,
     however, that the obligation to indemnify will be several, not joint and
     several, among such sellers of Restricted Shares, and the maximum amount of
     liability in respect of such indemnification shall be in proportion to and
     limited to, in the case of each seller of Restricted Shares, an amount
     equal to the net proceeds actually received by such seller from the sale of
     Restricted Shares effected pursuant to such registration.

(c)  The indemnification required by this Section 10 will be made by periodic
     payments during the course of the investigation or defense, as and when
     bills are received or expenses incurred, subject to prompt refund in the
     event any such payments are determined not to have been due and owing
     hereunder.

(d)  Promptly after receipt by an indemnified party of notice of the
     commencement of any action involving a claim referred to in the preceding
     paragraphs of this Section, such indemnified party will, if a claim in
     respect thereof is made against an indemnifying party, give written notice
     to the latter of the commencement of such action (it being understood that
     no delay in delivering or failure to deliver such notice shall relieve the
     indemnifying persons from any liability or obligation hereunder unless (and
     then solely to the extent that) the indemnifying person is prejudiced by
     such delay and/or failure).  In case any such action is brought against an
     indemnified party, the indemnifying party will be entitled to participate
     in and to assume the defense thereof, jointly with any other indemnifying
     party similarly notified to the extent that it may wish, with counsel
     reasonably satisfactory to such indemnified party, and after notice from
     the indemnifying party to such indemnified party of its election so to
     assume the defense thereof, the indemnifying party shall not be responsible
     for any legal or other expenses subsequently incurred by the latter in
     connection with the defense thereof; provided, however, that if any
     indemnified party shall have reasonably concluded that there may be one or
     more legal or equitable defenses available to such indemnified party which
     are additional to or conflict with those available to the indemnifying
     party, or that such claim or litigation involves or could have an effect
     upon matters beyond the scope of the indemnity agreement provided in this
     Section, the indemnifying party shall not have the right to assume the
     defense of such action on behalf of such indemnified party and such
     indemnifying party shall reimburse such indemnified party and any person
     controlling such indemnified party for that portion of the fees and
     expenses of any counsel retained by the indemnified party which is
     reasonably related to the matters covered by the indemnity agreement
     provided in this Section.

(e)  The indemnification provided for under this Agreement will remain in full
     force and effect regardless of any investigation made by or on behalf of
     the indemnified party or

                                      -20-
<PAGE>

     any officer, director or controlling person of such indemnified party and
     will survive the transfer of securities.

(f)  If the indemnification provided for in this Section 10 is held by a court
     of competent jurisdiction to be unavailable to an indemnified party with
     respect to any loss, claim, damage, liability or action referred to herein,
     then the indemnifying party, in lieu of indemnifying such indemnified party
     hereunder, shall contribute to the amounts paid or payable by such
     indemnified party as a result of such loss, claim, damage, liability or
     action in such proportion as is appropriate to reflect the relative fault
     of the indemnifying party on the one hand and of the indemnified party on
     the other in connection with the statements or omissions which resulted in
     such loss, claim, damage or liability as well as any other relevant
     equitable considerations.  The relative fault of the indemnifying party and
     of the indemnified party shall be determined by reference to, among other
     things, whether the untrue or alleged untrue statement of a material fact
     or the omission or alleged omission to state a material fact relates to
     information supplied by the indemnifying party or by the indemnified party
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission.  The Company
     and the sellers of Restricted Shares agree that it would not be just and
     equitable if contributions pursuant to this paragraph were determined by
     pro rata allocation or by any other method of allocation which did not take
     into account the equitable considerations referred to herein.  The amount
     paid or payable to an indemnified party as a result of the losses, claims,
     damages, liabilities or expenses referred to above shall be deemed to
     include, subject to the limitation set forth in the fourth paragraph of
     this Section 10, any legal or other expenses reasonably incurred in
     connection with investigating or defending the same.  Notwithstanding the
     foregoing, in no event shall the amount contributed by a seller of
     Restricted Shares exceed the aggregate net offering proceeds received by
     such seller from the sale of its Restricted Shares.

SECTION 11.  UNDERWRITING AGREEMENT.

          Notwithstanding the provisions of Sections 9 and 10, to the extent
that the Company and the holders selling Restricted Shares in a proposed
registration shall enter into an underwriting or similar agreement, which
agreement contains provisions covering one or more issues addressed in such
Sections, the provisions contained in such Sections addressing such issue or
issues shall be superseded with respect to such registration by such other
agreement.

SECTION 12.  INFORMATION BY HOLDERS.

          The holders selling Restricted Shares in a proposed registration shall
furnish to the Company such written information regarding such holder and the
distribution proposed by such holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Agreement.

SECTION 13.  EXCHANGE ACT COMPLIANCE.

          The Company shall comply with all of the reporting requirements of the
Exchange Act and with all other public information reporting requirements of the
Commission

                                      -21-
<PAGE>

which are conditions to the availability of Rule 144 for the sale of the Common
Stock. The Company shall cooperate with the Investor in supplying such
information as may be necessary for such Investor to complete and file any
information reporting forms presently or hereafter required by the Commission as
a condition to the availability of Rule 144.

SECTION 14.  NO CONFLICT OF RIGHTS.

          The Company represents and warrants to the Investors that the
registration rights granted to the Investors hereby do not conflict with any
other registration rights granted by the Company.  The Company shall not, after
the date hereof, grant any registration rights which conflict with the
registration rights granted hereby; provided, however, that such prohibition
shall not apply to the assumption by the Company of any registration right
obligations of Building One Services Corporation.

SECTION 15.  PROTECTIVE PROVISIONS.

(a)  Until the Maturity Date (assuming full payment and performance by the
     Company of all of its obligations as of such date, if the Company has not
     fully paid and performed all of its obligations as of such date, it being
     understood that the Company's obligations under this section shall survive
     until such obligations have been satisfied), and so long as (X) if the
     Convertible Preferred Stock has been converted into shares of Common Stock
     after the receipt by the holders of notice of the Company's intention to
     redeem the Convertible Preferred Stock pursuant to the Statement of
     Designations, then for two years from the date of such conversion, provided
     that, the Investor and its Affiliates hold in the aggregate Common Stock
     Equivalents representing at least 25% of the Conversion Shares issuable
     upon conversion of the Convertible Preferred Stock issued on the Closing

     Company and its Subsidiaries, and (ii) upon fair and reasonable terms no
     less favorable to the Company and its Subsidiaries than they would obtain
     in a comparable arm's length transaction with a Person which is not an

       agreement between the Company and a shareholder of the Company with

       agreement with a non-employee of the Company and involves less than
       10,000 shares of Common Stock (adjusted for stock splits, stock dividends
       and similar events after the date hereof);

(vi)   dispose of any business or asset, (whether by merger, consolidation, sale

       consideration) in excess of 2.0% of total assets of the Company;

(viii) hire or fire, or amend the employment terms of the Chairman of the Board

       amendment to any benefit plan or program in which employees of the
       Company participate generally;

(ix)   through any transaction or series of related transactions incur or
       refinance any Indebtedness; except that the Company and any of its
       Subsidiaries may incur or refinance any (x) Indebtedness under the Credit
       Agreement so long as at the time such Indebtedness is incurred and after
       giving effect to the incurrence thereof, the Consolidated Leverage Ratio
       of the Company is less than 4.0 to 1.0; (y) any other Indebtedness so
       long as at the time such Indebtedness is incurred and after giving effect
       to the incurrence thereof, the aggregate outstanding amount of all such
       Indebtedness shall not exceed 2 1/2% of the total assets of the Company;

                                      -23-
<PAGE>

(xi)   create or acquire any interest in any Subsidiary other than a wholly-
       owned Subsidiary unless, after giving effect to such acquisition, the

       exceed 1% of the Company's consolidated total assets as of the end of the
       last fiscal quarter;

(xii)  adopt or amend any Equity-Linked Plan or make any bonus payment to any
       (i) employee of the Company or (ii) any President of any Subsidiary in
       excess of $250,000 (except pursuant to the terms of the arrangements in
       effect on the Closing Date); or

(xiii) agree or otherwise commit to take any of the actions set forth above.

        (b) Until the Maturity Date (assuming full payment and performance by
the Company of all of its obligations as of such date, if the Company has not
fully paid and performed all of its obligations as of such date, it being
understood that the Company's obligations under this Section shall survive until
such obligations have been satisfied) in the event the Convertible Preferred
Stock has been converted into shares of Common Stock after the receipt by the
holders of notice of the Company's intention to redeem the Convertible Preferred
Stock pursuant to the Statement of Designations and two years has elapsed since
the date of such conversion, for so long as the Investor and its Affiliates hold
in the aggregate at least 10% of the outstanding Common Stock of the Company,
the Company shall not, and shall not permit any Subsidiary, without the prior
written consent of the Investor to take any of the following actions provided,
however, that nothing in this Section 15 shall prohibit any transaction between
the Company and one or more wholly owned Subsidiaries between or among wholly
owned Subsidiaries:

(i)   merge, consolidate or amalgamate with any person or entity, or sell all or
      substantially all of the assets of the Company or such Subsidiary (other
      than in connection with an acquisition or disposition of any business or
      assets for which the consent of the Investor is not required under clauses
      15(a)(vi) or (vii) above, unless prior to the consummation of such merger,
      consolidation, amalgamation or sale, the Company has paid the amount
      provided for in Section 15(c) below;

(ii)  enter into any transaction, including, without limitation, any purchase,
      sale, lease or exchange of property, the rendering of any service or the
      payment of any management, advisory or similar fees, with any Affiliate
      unless such transaction is (i) in the ordinary course of business of the
      Company and its Subsidiaries, and (ii) upon fair and reasonable terms no
      less favorable to the Company and its Subsidiaries than they would obtain
      in a comparable arm's length transaction with a Person which is not an

                                      -24-
<PAGE>

      executives are entitled resulting solely from an amendment to any benefit
      plan or program in which employees of the Company participate generally;
      or

(v)   agree or otherwise commit to take any of the actions set forth above.

        (c) If the Company requests that the Investor consent to a merger,
consolidation or amalgamation described in Section 15(a)(i) or 15(b)(i) (a
"Proposed Transaction") and the Investor fails to consent to such Proposed
Transaction within 15 days after delivery of such request, then the Company may
consummate the Proposed Transaction without the consent of the Investor,
provided the Company purchases from the Investor all of (i) the shares of
Convertible Preferred Stock and (ii) the shares of Common Stock of the Company
received upon conversion thereof, in each case that are held by the Investor as
of the date of the Election Notice (as defined below)((i) and (ii) together the
"Retained Shares"), on the terms specified herein. In the event the Company
elects to exercise the right of repurchase set forth herein, it shall deliver
written notice to the Investor (an "Election Notice") no less than 20 days prior
to the date of consummation of the Proposed Transaction. The purchase price of
the Retained Shares shall be a sum (the "Purchase Price") that would provide to
the Investor a 25% annual rate of return compounded quarterly, on the Original
Cost of the shares of Convertible Preferred Stock represented by the Retained
Shares, such return to be calculated from the Closing Date through the date of
consummation of the Proposed Transaction. The Investor shall and shall cause all
of its Affiliates to vote all their shares of capital stock of the Company (or
to execute one or more written consents) in favor of any Proposed Transaction as
to which it has received an Election Notice. The closing of the purchase of the
Retained Shares pursuant to this Section 15(c) shall take place on the date of
consummation of the Proposed Transaction at which time the Company shall pay to
the Investor the Purchase Price, and the Investor shall deliver or cause to be
delivered to the Company certificates representing the Retained Shares.

SECTION 16.  STANDSTILL.

          Except pursuant to Section 2 hereof, prior to the second anniversary
of the Closing Date, the Investor shall not purchase or agree to purchase or
otherwise acquire beneficial ownership of additional shares of Common Stock,
other than by conversion of the Convertible Preferred Stock in accordance with
the terms of the Statement of Designations or by exercise of its warrants to
purchase shares of common stock of Building One Services Corporation, if after
giving effect to such proposed purchase, the Investor and its Affiliates would
own in the aggregate Common Stock Equivalents equal to greater than 30% of the
outstanding Voting Stock of the Company on such date.

SECTION 17.  VOTING AGREEMENT.

          The Investor agrees to vote all shares of capital stock held by the
Investor (by proxy or in person) in favor of the slate of directors recommended
by the Board to the shareholders at the annual shareholders' meetings of the
Company to be held in 2000 and 2001 and to cause all other Affiliates of the
Investor to vote their shares of capital stock of the Company in such manner.
The Investor and its Affiliates shall not enter into any agreement or
arrangement that confers on any Person, other than an Affiliate of the Investor,
the right to vote

                                      -25-
<PAGE>

(or execute written consents with respect to) any shares of Convertible
Preferred Stock or Conversion Shares, while such securities are owned by the
Investor or its Affiliates.

SECTION 18.  MISCELLANEOUS.

        (a)  Restrictive Legends.

(i)   Each certificate for Restricted Shares (unless otherwise permitted by the
      provisions of Section 18(a) (ii)) shall include a legend in substantially
      the following form:

                 "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                 UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
                 SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD EXCEPT IN
                 COMPLIANCE THEREWITH.  THESE SECURITIES ARE SUBJECT TO
                 RESTRICTIONS ON VOTING, TRANSFER AND OTHER MATTERS AS SET FORTH
                 IN THE INVESTOR'S RIGHTS AGREEMENT DATED AS OF FEBRUARY 22,
                 2000;"

(ii)  Subject to Section 18(a)(iii), any holders of Restricted Shares registered
      pursuant to the Securities Act and qualified under applicable state
      securities laws may exchange certificates representing such Restricted
      Shares on transfer for new certificates that shall not bear the legend set
      forth in paragraph (i) of this Section 18(a);

(iii) Compliance with Securities Laws. Upon any proposed transfer of Restricted
      Shares, the Company shall register the transfer of such Restricted Shares
      on the stock transfer books of the Company if the Company shall have
      received (A) to the extent required to ensure compliance with the
      Securities Act, an opinion of counsel reasonably satisfactory to the
      Company, to the effect that the proposed transfer of Restricted Shares may
      be effected without registration under the Securities Act, (B)
      representation letters in form and substance reasonably satisfactory to
      the Company to ensure compliance with the provisions of the Securities Act
      and (C) the agreement of the transferee to comply with the provisions of
      Section 16 and 17 of this Agreement. Each certificate evidencing
      Restricted Shares transferred as above provided shall bear the legend set
      forth in Section 18(a)(i), except that such certificate shall not bear
      such legend if neither such legend nor the restrictions on transfer in
      Section 18(a) are required in order to ensure compliance with the
      provisions of the Securities Act.

        (b) Severability. Whenever possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, and such invalid, void or
otherwise unenforceable provisions shall be null and void. It is the intent of
the parties, however, that any invalid, void or otherwise unenforceable
provisions be automatically replaced by other

                                      -26-
<PAGE>

provisions which are as similar as possible in terms to such invalid, void or
otherwise unenforceable provisions but are valid and enforceable to the fullest
extent permitted by law.

        (c) Entire Agreement. This Agreement, together with the Subscription
Agreement, contains the entire agreement among the parties with respect to the
subject matter hereof and supersedes all prior arrangements or understandings
with respect hereto.

        (d) Successors and Assigns. This Agreement shall bind and inure to the
benefit of the Company and the Investor and their respective successors and
permitted assigns; provided, however, that each such person or entity shall, as
a condition to the effectiveness of such assignment, be required to execute a
counterpart to this Agreement whereupon such person or entity shall have the
benefits of, and shall be subject to the restrictions contained in, this
Agreement with respect to such Restricted Shares, including the provisions of
Section 16 and 17; provided, further, that the Investor shall not be entitled to
assign its rights under Sections 2, 3, 4 or 15 without the consent of the
Company other than to an Affiliate of the Investor.

        (e) Counterparts. This Agreement may be executed simultaneously in two
or more counterparts, any one of which need not contain the signatures of more
than one party, but all such counterparts taken together will constitute one and
the same agreement. It shall not be necessary in making proof of this Agreement
to produce or account for more than one such counterpart. The failure of any
Investor to execute this Agreement does not make it invalid as against any other
Investor.

        (f) Remedies. The Investor shall have all rights and remedies reserved
for such Investor pursuant to this Agreement and the Articles of Incorporation
and the By-laws of the Company, as amended, and all rights and remedies which
such Investor has been granted at any time under any other agreement or contract
and all of the rights which such holder has under any law or equity. Any person
having any rights under any provision of this Agreement will be entitled to
enforce such rights specifically, to recover damages by reason of any breach of
any provision of this Agreement and to exercise all other rights granted by law
or equity.

(i)  The parties hereto agree that if any parties seek to resolve any dispute
     arising under this Agreement pursuant to a legal proceeding, the prevailing
     parties to such proceeding shall be entitled to receive reasonable fees and
     expenses (including reasonable attorneys' fees and expenses) incurred in
     connection with such proceedings.

(ii) It is acknowledged that it will be impossible to measure in money the
     damages that would be suffered if the parties fail to comply with any of
     the obligations herein imposed on them and that in the event of any such
     failure, an aggrieved person will be irreparably damaged and will not have
     an adequate remedy at law.  Any such person shall, therefore, be entitled
     to injunctive relief, including specific performance, to enforce such
     obligations, and if any action should be brought in equity to enforce any
     of the provisions of this Agreement, none of the parties hereto shall raise
     the defense that there is an adequate remedy at law.

        (g) Notices. All notices, requests, consents and other communications

        (h) Governing Law; Jurisdiction; Venue; Process. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
without regard

                                      -28-
<PAGE>

to any choice of law or conflict of law provision or rule that would cause the
application of the laws of any jurisdiction other than the State of New York.
Any legal action in a proceeding brought in accordance with this Section shall
be brought in the courts of the State of New York or of the United States
District Court for the Southern District of New York, and by execution and
delivery of this Agreement, the parties hereby irrevocably accept for themselves
and in respect of their property, generally and unconditionally, the exclusive
jurisdiction of the aforesaid courts. The parties hereby irrevocably waive any
objection which they may now or hereafter have to laying of venue of any actions
or proceedings arising out of or in connection with this Agreement brought in
the courts referred to above and hereby further irrevocably waive and agree, not
to plead or claim in any such court that any such action or proceeding has been
brought in an inconvenient forum. The parties further agree that the mailing by
certified or registered mail, return receipt requested, of any process required
by any such court shall constitute valid and lawful service of process against
them, without necessity for service by any other means provided by statute or
rule of court.

(i)  Further Assurances.  Each party hereto shall do and perform or cause to be
     done and performed all such further acts and things and shall execute and
     deliver all such other agreements, certificates, instruments, and documents
     as any other party hereto reasonably may request in order to carry out the
     provisions of this Agreement and the consummation of the transactions
     contemplated hereby.

(j)  Modifications; Amendments; Waivers.  The terms and provisions of this
     Agreement may not be modified, amended or waived, except pursuant to a
     writing signed by the Company and the Investor, provided, however, Sections
     10 through 14 may be amended pursuant to a writing signed by the Company
     and the holders of a majority of the Restricted Shares .

(k)  Headings.  The headings of the various sections of this Agreement have been
     inserted for convenience of reference only and shall not be deemed to be a
     part of this Agreement.

(l)  Waiver.  No course of dealing between the Company and the Investor or any
     delay in exercising any rights hereunder will operate as a waiver of any
     rights of any party to this Agreement.  The failure of any party to enforce
     any of the provisions of this Agreement will in no way be construed as a
     waiver of such provisions and will not affect the right of such party
     thereafter to enforce each and every provision of this Agreement in
     accordance with its terms.

(m)  Mutual Waiver of Jury Trial.  BECAUSE DISPUTES ARISING IN CONNECTION WITH
     COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
     BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE
     AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES
     DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE
     LAWS.  THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE
     JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO
     TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO
     ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER THIS AGREEMENT OR ANY
     DOCUMENTS RELATED HERETO.

                                      -29-

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement on

                                                                   EXHIBIT 10.18


     WARRANT AGREEMENT dated as of November 25, 1997 between Consolidation
Capital Corporation, a Delaware corporation (the "Company"), and Friedman,
Billings, Ramsey & Co., Inc. (hereinafter referred to as the "Representative").

                              W I T N E S S E T H:

     WHEREAS, the Representative has agreed, pursuant to the underwriting
agreement (the "Underwriting Agreement") dated November 25, 1997 between the
Representative, as representative of the several Underwriters named in the
Underwriting Agreement (the "Underwriters") and the Company, to act as one of
the underwriters in connection with the Company's proposed initial public
offering (the "Public Offering") of 24,000,000 shares of Common Stock ("Public
Shares") at an initial public offering price of $20.00 per Public Share; and

     WHEREAS, the Company proposes to issue to the Representative, in its
individual capacity and not as representative of the several Underwriters
(defined below) warrants ("Warrants") to purchase up 1,130,000 shares of common
stock, par value $.001 per share ("Common Stock") (the shares of Common Stock
covered by the Warrants are referred to as "Shares"); and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to the Representative or officers or partners of the Representative
in consideration for, and as part of the Representative's compensation in
connection with, the Representative acting as one of the underwriters pursuant
to the Underwriting Agreement;

     NOW, THEREFORE, in consideration of the premises and the agreements herein
set forth and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

     1.  GRANT.

     The Representative, and/or any of its designees who are officers or
partners of the Representative is hereby granted the right to purchase, at any
time from November 25, 1998 until 5:00 P.M., New York City time, on November 25,
2002 (the "Warrant Exercise Term"), up to 1,130,000 shares of Common Stock at an
initial exercise price (subject to adjustment as provided in Article 8 hereof)
of $20.00 per Share.  Except as provided in Section 13 hereof, the Shares are in
all respects identical to the Public Shares being sold to the public pursuant to
the terms and provisions of the Underwriting Agreement.
<PAGE>

     2.  WARRANT CERTIFICATES.

     The warrant certificates (the "Warrant Certificates") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit
A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions and other variations as required or permitted by this
Agreement.

     3.  EXERCISE OF WARRANTS.

     3.1  CASH EXERCISE.  The Warrants initially are exercisable at a price of
$20.00 per Share purchased, payable in cash or by check to the order of the
Company, or any combination of cash or check, subject to adjustment as provided
in Article 8 hereof.  Upon surrender of the Warrant Certificate with the annexed
Form of Election to Purchase duly executed, together with payment of the
Exercise Price (as hereinafter defined) for the Shares purchased, at the
principal office of the Company (presently located at 1747 Pennsylvania Avenue,
NW, Suite 900, Washington, DC 20006) or at the office of its transfer agent, the
registered holder(s) of a Warrant Certificate ("Holder" or "Holders") shall be
entitled to receive a certificate or certificates for the Shares so purchased.
The purchase rights represented by each Warrant Certificate are exercisable at
the option of the Holder hereof, in whole or in part (but not as to fractional
Shares).  In the case of the purchase of less than all of the Shares purchasable
under any Warrant Certificate, the Company shall cancel said Warrant Certificate
upon the surrender thereof and shall execute and deliver a new Warrant
Certificate of like tenor for the balance of the Shares purchasable thereunder.

     3.2  CASHLESS EXERCISE.  At any time during the Warrant Exercise Term, the
Holder may, at its option, exchange this Warrant, in whole or in part (a
"Warrant Exchange"), into the number of Shares determined in accordance with
this Section 3.2, by surrendering this Warrant at the principal office of the
Company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Shares to be
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange").  The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date").  Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new warrant of
like tenor evidencing the balance of the Shares remaining subject to this
Warrant, shall be issued as of the Exchange Date and delivered to the Holder
within three (3) days following the Exchange Date.  In connection with any
Warrant Exchange, this Warrant shall represent the right to subscribe for and
acquire the number of Shares (rounded to the next highest integer) equal to (i)
the number of Shares specified by the Holder in its Notice of Exchange (the
"Total Number"), but in no case more than the number of shares equal to the
number of shares listed on the warrant certificate, less (ii) the number of
Shares equal to the quotient obtained by dividing (A) the product of the Total
Number and the existing Exercise Price (as hereinafter defined) by (B) the
current market value of a Public Share.
<PAGE>

     4.  ISSUANCE OF CERTIFICATES.

     Upon the exercise of the Warrants, the issuance of certificates for the
Shares purchased shall be made forthwith (and in any event within three business
days thereafter) without charge to the Holder thereof including, without
limitation, any tax which may be payable in respect of the issuance thereof, and
such certificates shall (subject to the provisions of Article 5 hereof) be
issued in the name of, or in such names as may be directed by, the Holder
thereof; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of any such certificates in a name other than that of the Holder and
the Company shall not be required to issue or deliver such certificates unless
or until the person or persons requesting the issuance thereof shall have paid
to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

     The Warrant Certificates and the certificates representing the Shares shall
be executed on behalf of the Company by the manual or facsimile signature of the
present or any future Chairman or Vice Chairman of the Board of Directors or
President or Vice President of the Company under its corporate seal reproduced
thereon, attested to by the manual or facsimile signature of the present or any
future Secretary or Assistant Secretary of the Company.  Warrant Certificates
shall be dated the date of execution by the Company upon initial issuance,
division, exchange, substitution or transfer.

     Upon exercise, in part or in whole, of the Warrants, certificates
representing the Shares shall bear a legend substantially similar to the
following:

     "The securities represented by this certificate and the other securities
     issuable upon exercise thereof have not been registered under the
     Securities Act of 1933, as amended (the "Act"), and may not be offered or
     sold except (i) pursuant to an effective registration statement under the
     Act, (ii), to the extent applicable, pursuant to Rule 144 under the Act (or
     any similar rule under such Act relating to the disposition of securities),
     or (iii) upon the delivery by the holder to the Company of an opinion of
     counsel, reasonably satisfactory to counsel to the Company, stating that an
     exemption from registration under such Act is available."

     5.   RESTRICTION ON TRANSFER OF WARRANTS.

     The Holder of a Warrant Certificate, by its acceptance thereof, covenants
and agrees that the Warrants are being acquired as an investment and not with a
view to the distribution thereof, and that the Warrants may not be sold,
transferred, assigned, hypothecated or otherwise disposed of, in whole or in
part, except (i) to officers, directors or affiliates of the Representative (ii)
to transferees whom in the opinion of counsel to the Company qualify for an
exemption from the Act pursuant to a section 4 (1 1/2) analysis.  The Warrant
Certificate may bear a legend substantially similar to the following: .
<PAGE>

     6.   PRICE.

     6.1  INITIAL AND ADJUSTED EXERCISE PRICE.  The initial exercise price of
each Warrant shall be $20.00 per Share.  The adjusted exercise price shall be
the price which shall result from time to time from any and all adjustments of
the initial exercise price in accordance with the provisions of Article 8
hereof.

     6.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, depending upon the
context.

     7.   REGISTRATION RIGHTS.

     7.1  REGISTRATION UNDER THE SECURITIES ACT OF 1933.  None of the Warrants
nor the Shares have been registered for purposes of public distribution under
the Securities Act of 1933, as amended (the "Act").

     7.2  REGISTRABLE SECURITIES.  As used herein the term "Registrable
Security" means each of the Shares and any Common Stock issued upon any stock
split or stock dividend in respect of such Shares; provided, however, that with
respect to any particular Registrable Security, such security shall cease to be
a Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Act and disposed of pursuant thereto, (ii)
registration under the Act is no longer required for subsequent sale of such
security or (iii) it has ceased to be outstanding.  The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security."  In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Article 7.

     7.3  PIGGYBACK REGISTRATION.

          (a) If, at any time during the seven years following the date of this
Agreement, the Company proposes to prepare and file one or more registration
statement(s) filed in connection with a public offering covering equity
securities of the Company, or any such securities of the Company held by its
shareholders (other than in connection with an exchange offer, a "rights"
offering to shareholders, an offering relating to an employee benefit plan,
dividend reinvestment plan, an acquisition, a merger, the conversion of any
convertible securities, an exchange of a security, or a stand-by underwriting
with respect to the call of a warrant, option, right or convertible security for
redemption), (for purposes of this Article 7, collectively, a "Registration
Statement"), it will give written notice of its intention to do so by registered
mail ("Notice"), at least thirty (30) business days prior to the filing of each
such Registration Statement, to all holders of the Registrable Securities or, in
the event that the Company has not formulated its intent to file such
Registration
<PAGE>

Statement at least thirty (30) calendar days before the anticipated filing date
of the Registration Statement, as soon as practicable upon the formation by the
Company of such intent. However, no such Notice need be given if the
Registration Statement is for an underwritten offering of securities other than
equity securities or securities convertible into equity securities. Upon the
written request of such a holder (a "Requesting Holder"), made within twenty
(20) business days after receipt of the Notice, that the Company include any of
the Requesting Holder's Registrable Securities in the proposed Registration
Statement, the Company shall, as to each such Requesting Holder, use its best
efforts to effect the registration under the Act of the Registrable Securities
which it has been so requested to register ("Piggyback Registration"), at the
Company's sole cost and expense and at no cost or expense to the Requesting
Holders. The Company shall not be required to honor any such request (i) if, in
opinion of counsel to the Company reasonably acceptable to such Holder who
wishes to have such Registrable Securities included in such Registration
Statement, registration under the Act is not required for the transfer of the
Registrable Securities in the manner proposed by such Holder; or (ii) to
register in the aggregate fewer than 25,000 Shares held by the Holders. The
Company shall permit, or shall use its best efforts to cause the managing
underwriter of a proposed offering to permit, the Holders of Registrable
Securities requested to be included in the registration (the "Piggy-Back
Shares") to include such Piggy-Back Shares in the proposed offering on the same
terms and conditions as applicable to the shares of Common Stock offered by the
Company and for the account of any person other than the Company, as the case
may be.

          (b) Notwithstanding the foregoing, if any such managing underwriter
shall advise the Company in writing that, in its opinion, the distribution of
all or a portion of the Registrable Securities requested to be included in the
Registration Statement concurrently with the shares of Common Stock being
registered by the Company would materially adversely affect the distribution of
such securities by the Company for its own account, or for the account of any
person or persons other than the Company that have asserted, with respect to
such registration, demand registration rights under any other agreement, then
such inclusion of Registrable Securities shall be made pro rata among the
aggregate of the Registrable Securities for which a proper request was made
under this subsection 7.3 and any other securities properly requested to be
included in the registration by other holders pursuant to piggy-back or
incidental registration rights under any other agreement.

     7.4  DEMAND REGISTRATION.

          (a) At any time during the Warrant Exercise Term, any "Majority
Holder" (as such term is defined in Section 7.4(c) below) of the Registrable
Securities shall have the right (which right is in addition to the piggyback
registration rights provided for under Section 7.3 hereof), exercisable by
written notice to the Company (the "Demand Registration Request"), to have the
Company prepare and file with the Securities and Exchange Commission (the
"Commission"), on one occasion, at the sole expense of the Company, a
Registration Statement and such other documents, including a prospectus, as may
be necessary (in the opinion of both counsel for the Company and counsel for
such Majority Holder), in order to comply with the provisions of the Act, so as
to permit a public offering and sale of the Registrable Securities by the
holders thereof, for
<PAGE>

twelve (12) consecutive months. The Company shall not be required to file any
amendments to the Registration Statement required by this subsection 7.4(a)
except as is necessary to keep the disclosure about the Company current.

          (b) The Company covenants and agrees to give written notice of any
Demand Registration Request to all holders of the Registrable Securities within
ten (10) days from the date of the Company's receipt of any such Demand
Registration Request.  After receiving notice from the Company as provided in
this Section 7.4(b), holders of Registrable Securities may request the Company
to include their Registrable Securities in the Registration Statement to be
filed pursuant to Section 7.4(a) hereof by notifying the Company of their
decision to include such securities within ten (10) days of their receipt of the
Company's notice.

          (c) The term "Majority Holder" as used in this Section 7.4 shall mean
any holder or any combination of holders of Registrable Securities, if included
in such holders' Registrable Securities are that aggregate number of Shares
(including Shares already issued and Shares issuable pursuant to the exercise of
outstanding Warrants) as would constitute a majority of the aggregate number of
Shares (including Shares already issued and Shares issuable pursuant to the
exercise of outstanding Warrants) included in all of the Registrable Securities.

     7.5  COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  The Company
covenants and agrees as follows:

          (a) In connection with any registration under Section 7.4 hereof, the
Company shall file the Registration Statement as expeditiously as possible, but
in no event later than thirty (30) days following receipt of any demand
therefor, shall use its best efforts to have any such Registration Statements
declared effective at the earliest possible time.  If a written request,
however, is received by the Company that would require the filing of a
Registration Statement between 45 and 105 days after the end of its fiscal year,
the deadline for the filing of the Registration Statement shall be extended
until the 106th day of such fiscal year.  The Company shall furnish each holder
of Registrable Securities such number of prospectuses as shall reasonably be
requested.  However, in connection with any registration under Sections 7.3 and
7.4 hereof, the Company shall have sole control in connection with the
preparation, filing, amending and supplementing of the Registration Statement,
including the right to withdraw the same or delay the effectiveness thereof
when, in the sole judgment of the Board of Directors of the Company, the filing
or pendency of such registration statement or the effectiveness thereof would
impose an undue burden upon the ability by the Company to proceed with any other
material financing for its own account or any material corporate transaction,
including, but not limited to, a reorganization, recapitalization, merger,
consolidation or material acquisition of the securities or assets of another
firm or corporation; provided, however, that the Company's exercise of any such
right of withdrawal or delay shall not be deemed a waiver of the rights of the
Holders, and the Company shall be required to file a new Registration Statement
or to proceed with such actions as reasonably may be required to cause the
Registration Statement to become effective within a reasonable time
<PAGE>

after the consummation of the event or transaction which required such
withdrawal or delay.

          (b) The Company shall pay all costs, fees and expenses in connection
with all Registration Statements filed pursuant to Sections 7.3 and 7.4(a)
hereof including, without limitation, the Company's legal and accounting fees,
printing expenses, and blue sky fees and expenses.  Each Holder, however, shall
pay the underwriting discount attributable to such Holder's Registrable
Securities, any transfer tax payable with respect thereto and the fees and
expenses of such Holder's counsel.

          (c) The Company will take all necessary action which may be required
in qualifying or registering the Registrable Securities included in a
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are requested by the holders of such securities, provided
that the Company shall not be obligated to execute or file any general consent
to service of process or to qualify as a foreign corporation to do business
under the laws of any such jurisdiction.

          (d) The Company shall indemnify any holder of the Registrable
Securities to be sold pursuant to any Registration Statement and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls such holder or underwriter or person deemed to be an underwriter within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from such Registration Statement to the same extent and with the same effect as
the provisions pursuant to which the Company has agreed to indemnify the
Underwriters contained in Section 8 of the Underwriting Agreement and shall
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

          (e) Any holder of Registrable Securities to be sold pursuant to a
Registration Statement, and its successors and assigns, shall severally, and not
jointly, indemnify the Company, its officers and directors and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished in writing by or on behalf of such holder, or its successors or
assigns, for specific inclusion in such Registration Statement to the same
extent and with the same effect as the provisions contained in Section 8 of the
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company and shall provide for just and equitable contribution as
set forth in Section 8 of the Underwriting Agreement.
<PAGE>

          (f) Nothing contained in this Agreement shall be construed as
requiring any Holder to exercise his Warrants prior to the initial filing of any
Registration Statement or the effectiveness thereof.

          (g) If the Company shall fail to comply with the provisions of this
Article 7, the Company shall, in addition to any other equitable or other relief
available to the holders of Registrable Securities, be liable for any or all
incidental, special and consequential damages sustained by the holders of
Registrable Securities that request registration of their Registrable
Securities.

          (h) Except as set forth in Section 7.5(j) hereof, the Company shall
not permit the inclusion of any securities other than the Registrable Securities
to be included in any Registration Statement filed pursuant to Section 7.4
hereof, or permit a Registration Statement relating to an underwritten offering
of the same securities as the Registrable Securities to be filed during an
underwritten offering of the Registrable Securities covered by a Registration
Statement filed pursuant to Section 7.4 hereof, without the prior written
consent of the Majority Holders, which consent shall not be unreasonably
withheld.

          (i) The Company shall deliver promptly to each holder of Registrable
Securities participating in the offering in which such Holder's shares are being
registered pursuant to Section 7.3 hereof and requesting the correspondence and

Securities Dealers, Inc.  Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at

Securities, the Company shall include in the Registration Statement filed for a

     8.   ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SECURITIES.  The following
adjustments apply to the Exercise Price of the Warrants with respect to the
Shares and the number of Shares purchasable upon exercise of the Warrants.

     8.1  COMPUTATION OF ADJUSTED PRICE.  In case the Company shall at any time
after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to its stockholders, then upon such
dividend or distribution the Exercise Price in effect immediately prior to such
dividend or distribution shall forthwith be reduced to a price determined by
dividing:

          (a) an amount equal to the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution multiplied by the
Exercise Price in effect immediately prior to such dividend or distribution, by

          (b) the total number of shares of Common Stock outstanding immediately
after such issuance or sale.

          For the purposes of any computation to be made in accordance with the
provisions of this Section 8.1, the shares of Common Stock issuable by way of a
dividend or other distribution on any shares of Common Stock of the Company
shall be deemed to have been issued immediately after the opening of business on
the date following the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution.

     8.2  SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding shares of Common Stock, the Exercise Price
shall forthwith be proportionately decreased in the case of a subdivision or
increased in the case of a combination.

     8.3  ADJUSTMENT IN NUMBER OF SECURITIES.  Upon each adjustment of the
Exercise Price pursuant to the provisions of this Article 8, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full Share by multiplying a number equal
<PAGE>

to the Exercise Price in effect immediately prior to such adjustment by the
number of Shares issuable upon exercise of the Warrants immediately prior to
such adjustment and dividing the product so obtained by the adjusted Exercise
Price.

     8.4  RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the Shares immediately prior to
any such events and at an aggregate price equal to the product of (x) the number
of shares of Common Stock issuable upon exercise of the Holders' Warrants and
(y) the Exercise Price in effect immediately prior to the record date for such
reclassification, change, consolidation, merger, sale or conveyance as if such
Holders had exercised the Warrants.

     8.5  DETERMINATION OF OUTSTANDING COMMON STOCK.  The number of shares of
Common Stock at any one time outstanding shall include the aggregate number of
shares issued or issuable upon the exercise of options, rights, warrants and
upon the conversion or exchange of convertible or exchangeable securities.

     8.6  SUBSCRIPTION RIGHTS FOR COMMON STOCK OR OTHER SECURITIES.  In the case
that the Company or an affiliate of the Company shall at any time after the date
hereof and prior to the exercise of all of the Warrants issue any rights to
subscribe for shares of Common Stock or any other securities of the Company or
of such affiliate to all of the shareholders of the Company, the Holders of the
unexercised Warrants shall be entitled, in addition to the shares of Common
Stock or other securities receivable upon the exercise of the Warrants, to
receive at the time such rights as are distributed to the other shareholders of
the Company.

     9.   EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.
<PAGE>

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

     10.  ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of Shares upon the exercise of the Warrants nor shall it be required
to issue scrip or pay cash in lieu of fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Shares.

     11.  RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized Common Stock, solely for the purpose of issuance upon the exercise of
the Warrants, such number of shares of Common Stock as shall be issuable upon
the exercise thereof.  The Company covenants and agrees that, upon exercise of
the Warrants and payment of the Exercise Price therefor, all Shares issuable
upon such exercise shall be duly and validly issued, fully paid, non-assessable
and not subject to the preemptive rights of any shareholder.  As long as the
Warrants shall be outstanding, the Company shall use its best efforts to cause
all shares of Common Stock issuable upon the exercise of the Warrants to be
listed on or quoted by the Nasdaq National Market, or listed on such national
securities exchanges as requested by the Underwriter.

     12.  NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
stockholder in respect of any meetings of stockholders for the election of
directors or any other matter, or as having any rights whatsoever as a
stockholder of the Company.  If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

          (a) the Company shall take a record of all of the holders of its
     shares of Common Stock for the purpose of entitling them to receive a
     dividend or distribution payable otherwise than in cash, or a cash dividend
     or distribution payable otherwise than out of current or retained earnings,
     as indicated by the accounting treatment of such dividend or distribution
     on the books of the Company; or

          (b) the Company shall offer to all of the holders of its shares of
     Common Stock any additional shares of capital stock of the Company or
     securities convertible into or
<PAGE>

     exchangeable for shares of capital stock of the Company, or any option,
     right or warrant to subscribe therefor; or

          (c) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed; or

          (d) reclassification or change of the outstanding shares of Common
     Stock (other than a change in par value to no par value, or from no par
     value to par value, or as a result of a subdivision or combination),
     consolidation of the Company with, or merger of the Company into, another
     corporation (other than a consolidation or merger in which the Company is
     the surviving corporation and which does not result in any reclassification
     or change of the shares of outstanding Common Stock, except a change as a
     result of a subdivision or combination of such shares or a change in par
     value, as aforesaid), or a sale or conveyance to another corporation of the
     property of the Company as an entirety is proposed; or

          (e) the Company or an affiliate of the Company shall propose to issue
     any rights to subscribe for shares of Common Stock or any other securities
     of the Company or of such affiliate to all the stockholders of the Company;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable securities or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

     13.  NOTICES.

     All of notices, requests, consents and other communications hereunder shall
be in writing and shall be deemed to have been duly made when delivered, or
mailed by registered or certified mail, return receipt requested:

     Holder as shown on the books of the Company; or

          (b)  If to the Company, to the address set forth in Section 3 of this
     Agreement or to
<PAGE>

     such other address as the Company may designate by notice to the Holders.

     14.  SUPPLEMENTS AND AMENDMENTS.

     The Company and the Representative may from time to time supplement or
amend this Agreement without the approval of any Holders of Warrant Certificates
in order to cure any ambiguity, to correct or supplement any provision contained

earlier date when all Warrants have been exercised and all Shares have been

deemed to be a contract made under the laws of the State of Delaware and for all
purposes shall be construed in accordance with the laws of said State.

     18.  BENEFITS OF THIS AGREEMENT.

corporation other than the Company and the Underwriter and any other registered
holder or holders of the Warrant Certificates, or Shares any legal or equitable

on November 25, 2002 ("Expiration Date"), up to 1,130,000 fully paid and non-
assessable shares ("Shares") of the Common Stock, par value $.001 per share
("Common Stock"), of Consolidation Capital Corporation, a Delaware corporation
(the "Company"), at the initial exercise price, subject to adjustment in certain
events (the "Exercise Price"), of $20.00 per Share, upon surrender of this
Warrant Certificate and payment of the Exercise Price at an office or agency of
the Company, but subject to the conditions set forth herein and in the warrant

Certificate at an office or agency of the Company, a new Warrant Certificate or

     WARRANT AGREEMENT dated as of November 25, 1997 between Consolidation
Capital Corporation, a Delaware corporation (the "Company"), and Jonathan J.

                                 W I T N E S S E T H:

     WHEREAS, the Company proposes to issue to Mr. Ledecky warrants ("Warrants")
to purchase 1,950,000 shares of common stock, par value $.001 per share ("Common
Stock"), on the closing date of the initial public offering (the shares of
Common Stock covered by the Warrants are referred to as the "Shares");

     WHEREAS the Company in connection with its initial public offering has
entered into an underwriting agreement with Friedman, Billings, Ramsey & Co.,
Inc. dated November 25, 1997 (the "Underwriting Agreement"); and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to Mr. Ledecky in connection with the Company's initial public
offering and in view of his interest in having the ability to purchase
additional shares of Common Stock in the Company;

     NOW, THEREFORE, in consideration of the premises and the agreements herein
set forth and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

     1.  GRANT.

     Mr. Ledecky is hereby granted the right to purchase, at any time from
November 25, 1997  until 5:00 p.m., Washington, D.C. time, on November 25, 2007
(the "Warrant Exercise Term"), 1,950,000 shares of Common Stock on the closing
date of the initial public offering at an initial exercise price (subject to
adjustment as provided in Article 7 hereof) of $20.00 per Share.  Except as
provided in Section 12 hereof, the Shares are in all respects identical to the
public shares being sold to the public pursuant to the terms and provisions of
the Underwriting Agreement.

     2.  WARRANT CERTIFICATES.

     The warrant certificates (the "Warrant Certificates") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit

omissions, substitutions and other variations as required or permitted by this
Agreement.
<PAGE>

     3.  EXERCISE OF WARRANTS.

     3.1  CASH EXERCISE.  The Warrants initially are exercisable at a price of
$20.00 per Share purchased, payable in cash or by check to the order of the
Company, or any combination of cash or check, subject to adjustment as provided
in Article 7 hereof.  Upon surrender of the Warrant Certificate with the annexed
Form of Election to Purchase duly executed, together with payment of the
Exercise Price (as hereinafter defined) for the Shares purchased, at the
principal office of the Company (presently located at 1747 Pennsylvania Avenue,
NW, Suite 900, Washington, D.C. 20006) or at the office of its transfer agent,
the registered holder(s) of a Warrant Certificate ("Holder" or "Holders") shall
be entitled to receive a certificate or certificates for the Shares so
purchased.  The purchase rights represented by each Warrant Certificate are
exercisable at the option of the Holder hereof, in whole or in part (but not as
to fractional Shares).  In the case of the purchase of less than all of the
Shares purchasable under any Warrant Certificate, the Company shall cancel said
Warrant Certificate upon the surrender thereof and shall execute and deliver a
new Warrant Certificate of like tenor for the balance of the Shares purchasable
thereunder.



     4.  RESTRICTION ON TRANSFER.

     The Holder of a Warrant Certificate, by its acceptance thereof, covenants
and agrees that the Warrants are being acquired as an investment and not with a
view to the distribution thereof, and that the Warrants may not be sold,
transferred, assigned, hypothecated or otherwise disposed of, in whole or in
part, except (i) to officers, directors or affiliates of Mr. Ledecky or (ii) to
transferees whom with the opinion of counsel, acceptable to the Company and the
transferor, that such transfer is exempt from registration under the Securities
Act of 1933, as amended (the "Act").  The Warrant Certificate issued pursuant to
(ii) above will bear a legend stating that the Warrants may only be exercised if
there is an applicable exemption under the Act, for the issuance of shares of
Common Stock of the Company upon the exercise of the Warrants.

     Additionally, upon exercise, in part or in whole, of the Warrants,
certificates representing the Shares shall bear a legend substantially similar
to the following:

     "The securities represented by this certificate and the other securities
     issuable upon exercise thereof have not been registered under the Act, and
     may not be offered or sold except (i) pursuant to an effective registration
     statement under the Act, (ii), to the extent applicable, pursuant to Rule
     144 under the Act (or any similar rule under such Act relating to the
     disposition of securities), or (iii) upon the delivery by the holder to the
     Company of an opinion of counsel, reasonably satisfactory to counsel to the
     Company, stating that an exemption from registration under such Act is
     available."
<PAGE>

     5.  PRICE.

     5.1  INITIAL AND ADJUSTED EXERCISE PRICE.  The initial exercise price of
each Warrant shall be $20.00 per Share.  The adjusted exercise price shall be
the price which shall result from time to time from any and all adjustments of
the initial exercise price in accordance with the provisions of Article 7
hereof.

     5.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, depending upon the
context.


     6.  REGISTRATION RIGHTS.

     6.1  REGISTRATION UNDER THE SECURITIES ACT OF 1933.  None of the Warrants
nor the Shares have been registered for purposes of public distribution under
the Act.

     6.2  REGISTRABLE SECURITIES.  As used herein the term "Registrable
Security" means each of the Shares and any Common Stock issued upon any stock
split or stock dividend in respect of such Shares; provided, however, that with
respect to any particular Registrable Security, such security shall cease to be
a Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Act and disposed of pursuant thereto, (ii)
registration under the Act is no longer required for subsequent sale of such
security or (iii) it has ceased to be outstanding.  The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security."  In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Article 7.

     6.3  PIGGYBACK REGISTRATION.

          (a) If, at any time during the twelve years following the date of this
Agreement, the Company proposes to prepare and file one or more registration
statement(s) filed in connection with a public offering covering equity
securities of the Company, or any such securities of the Company held by its
shareholders (other than in connection with an exchange offer, a "rights"
offering to shareholders, an offering relating to an employee benefit plan,
dividend reinvestment plan, an acquisition, a merger, the conversion of any
convertible securities, an exchange of a security, or a stand-by underwriting
with respect to the call of a warrant, option, right or convertible security for
redemption), (for purposes of this Article 7, collectively, a "Registration
Statement"), it will give written notice of its intention to do so by registered
mail ("Notice"), at least thirty (30) business days prior to the filing of each
such Registration Statement, to all holders of the Registrable Securities or, in
the event that the Company has not formulated its intent to file such
Registration Statement at least thirty (30) calendar days before the anticipated
filing date of the Registration Statement, as soon as practicable upon the
formation by the Company of such intent.  However, no such Notice need
<PAGE>

be given if the Registration Statement is for an underwritten offering of
securities other than equity securities or securities convertible into equity
securities. Upon the written request of such a holder (a "Requesting Holder"),
made within twenty (20) business days after receipt of the Notice, that the
Company include any of the Requesting Holder's Registrable Securities in the
proposed Registration Statement, the Company shall, as to each such Requesting
Holder, use its best efforts to effect the registration under the Act of the
Registrable Securities which it has been so requested to register ("Piggyback
Registration"), at the Company's sole cost and expense and at no cost or expense
to the Requesting Holders. The Company shall not be required to honor any such
request (i) if, in the opinion of counsel to the Company reasonably acceptable
to such Holder who wishes to have such Registrable Securities included in such
Registration Statement, registration under the Act is not required for the
transfer of the Registrable Securities in the manner proposed by such Holder; or
(ii) to register in the aggregate fewer than 25,000 Shares held by the Holders.
The Company shall permit, or shall use its best efforts to cause the managing
underwriter of a proposed offering to permit, the Holders of Registrable
Securities requested to be included in the registration (the "Piggy-Back
Shares") to include such Piggy-Back Shares in the proposed offering on the same
terms and conditions as applicable to the shares of Common Stock offered by the
Company and for the account of any person other than the Company, as the case
may be.

          (b) Notwithstanding the foregoing, if any such managing underwriter
shall advise the Company in writing that, in its opinion, the distribution of
all or a portion of the Registrable Securities requested to be included in the
Registration Statement concurrently with the shares of Common Stock being
registered by the Company would materially adversely affect the distribution of
such securities by the Company for its own account, or for the account of any
person or persons other than the Company that have asserted, with respect to
such registration, demand registration rights under any other agreement, then
such inclusion of Registrable Securities shall be made pro rata among the
aggregate of the Registrable Securities for which a proper request was made
under this subsection 6.3 and any other securities properly requested to be
included in the registration by other holders pursuant to piggy-back or
incidental registration rights under any other agreement.

     6.4  DEMAND REGISTRATION.

          (a) At any time during the Warrant Exercise Term, any "Majority
Holder" (as such term is defined in Section 6.4(c) below) of the Registrable
Securities shall have the right (which right is in addition to the piggyback
registration rights provided for under Section 6.3 hereof), exercisable by
written notice to the Company (the "Demand Registration Request"), to have the
Company prepare and file with the Securities and Exchange Commission (the
"Commission"), on one occasion, at the sole expense of the Company, a
Registration Statement and such other documents, including a prospectus, as may
be necessary (in the opinion of both counsel for the Company and counsel for
such Majority Holder), in order to comply with the provisions of the Act, so as
to permit a public offering and sale of the Registrable Securities by the
holders thereof, for twelve (12) consecutive months.  The Company shall not be
required to file any amendments to the Registration Statement required by this
subsection 6.4(a) except as is necessary to keep the disclosure about the
Company current.
<PAGE>

          (b) The Company covenants and agrees to give written notice of any
Demand Registration Request to all holders of the Registrable Securities within
ten (10) days from the date of the Company's receipt of any such Demand
Registration Request.  After receiving notice from the Company as provided in
this Section 6.4(b), holders of Registrable Securities may request the Company
to include their Registrable Securities in the Registration Statement to be
filed pursuant to Section 6.4(a) hereof by notifying the Company of their
decision to include such securities within ten (10) days of their receipt of the
Company's notice.

          (c) The term "Majority Holder" as used in this Section 6.4 shall mean
any holder or any combination of holders of Registrable Securities, if included
in such holders' Registrable Securities are that aggregate number of Shares
(including Shares already issued and Shares issuable pursuant to the exercise of
outstanding Warrants) as would constitute a majority of the aggregate number of
Shares (including Shares already issued and Shares issuable pursuant to the
exercise of outstanding Warrants) included in all of the Registrable Securities.

     6.5  COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  The Company
covenants and agrees as follows:

          (a) In connection with any registration under Section 6.4 hereof, the
Company shall file the Registration Statement as expeditiously as possible, but
in no event later than thirty (30) days following receipt of any demand
therefor, shall use its best efforts to have any such Registration Statement
declared effective at the earliest possible time.  If a written request,
however, is received by the Company that would require the filing of a
Registration Statement between 45 and 105 days after the end of its fiscal year,
the deadline for the filing of the Registration Statement shall be extended
until the 106th day of such fiscal year.  The Company shall furnish each holder
of Registrable Securities such number of prospectuses as shall reasonably be
requested.  However, in connection with any registration under Sections 6.3 and
6.4 hereof, the Company shall have sole control in connection with the
preparation, filing, amending and supplementing of the Registration Statement,
including the right to withdraw the same or delay the filing or effectiveness
thereof when, in the sole judgment of the Board of Directors of the Company, the
filing or pendency of such registration statement or the effectiveness thereof
would impose an undue burden upon the ability by the Company to proceed with any
other material financing for its own account or any material corporate
transaction, including, but not limited to, a reorganization, recapitalization,
merger, consolidation or material acquisition of the securities or assets of
another firm or corporation; provided, however, that the Company's exercise of
any such right of withdrawal or delay shall not be deemed a waiver of the rights
of the Holders, and the Company shall be required to file a new Registration
Statement or to proceed with such actions as reasonably may be required to cause
the Registration Statement to become effective within a reasonable time after
the consummation of the event or transaction which required such withdrawal or
delay.

          (b) The Company shall pay all costs, fees and expenses in connection
with all Registration Statements filed pursuant to Sections 6.3 and 6.4(a)
hereof including, without limitation, the Company's legal and accounting fees,
printing expenses, and blue sky fees and
<PAGE>

expenses. Each Holder, however, shall pay the underwriting discount attributable
to such Holder's Registrable Securities, any transfer tax payable with respect
thereto and the fees and expenses of such Holder's counsel.

          (c) The Company will take all necessary action which may be required
in qualifying or registering the Registrable Securities included in a
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are requested by the holders of such securities, provided
that the Company shall not be obligated to execute or file any general consent
to service of process or to qualify as a foreign corporation to do business
under the laws of any such jurisdiction.

          (d) The Company shall indemnify any holder of the Registrable
Securities to be sold pursuant to any Registration Statement and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls such holder or underwriter or person deemed to be an underwriter within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from such Registration Statement to the same extent and with the same effect as
the provisions pursuant to which the Company has agreed to indemnify the
underwriters contained in Section 8 of the Underwriting Agreement and shall
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

          (e) Any holder of Registrable Securities to be sold pursuant to a
Registration Statement, and its successors and assigns, shall severally, and not
jointly, indemnify the Company, its officers and directors and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished in writing by or on behalf of such holder, or its successors or
assigns, for specific inclusion in such Registration Statement to the same
extent and with the same effect as the provisions contained in Section 8 of the
Underwriting Agreement pursuant to which the underwriters have agreed to
indemnify the Company and shall provide for just and equitable contribution as
set forth in Section 8 of the Underwriting Agreement.

          (f) Nothing contained in this Agreement shall be construed as
requiring any Holder to exercise his Warrants prior to the initial filing of any
Registration Statement or the effectiveness thereof.

          (g) If the Company shall fail to comply with the provisions of this
Article 6, the Company shall, in addition to any other equitable or other relief
available to the holders of Registrable Securities, be liable for any or all
incidental, special and consequential damages
<PAGE>

sustained by the holders of Registrable Securities that request registration of
their Registrable Securities.

          (h) Except as set forth in Section 6.5(j) hereof, the Company shall
not permit the inclusion of any securities other than the Registrable Securities
to be included in any Registration Statement filed pursuant to Section 6.4
hereof, or permit a Registration Statement relating to an underwritten offering
of the same securities as the Registrable Securities to be filed during an
underwritten offering of the Registrable Securities covered by a Registration
Statement filed pursuant to Section 7.4 hereof, without the prior written
consent of the Majority Holders, which consent shall not be unreasonably
withheld.

          (i) The Company shall deliver promptly to each holder of Registrable
Securities participating in the offering in which such Holder's shares are being
registered pursuant to Section 6.3 hereof and requesting the correspondence and
memoranda described in this Section 6.5(i) and to the managing underwriter, if
any, copies of all correspondence between the Commission and the Company, its
counsel or auditors and all memoranda relating to discussions with the
Commission or its staff with respect to the Registration Statement and permit
each holder of Registrable Securities and underwriters to do such investigation,
upon reasonable advance notice, with respect to information contained in or
omitted from the Registration Statement as it deems reasonably necessary to
comply with applicable securities laws or rules of the National Association of
Securities Dealers, Inc.  Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as any such holder of Registrable Securities
or underwriter shall reasonably request.

          (j) Upon the written request therefor by any holders of Registrable
Securities, the Company shall include in the Registration Statement filed for an
underwritten offering covering any such holders Registrable Securities, any
additional shares of Common Stock of the Company, or,  with the approval of the
managing underwriter, any additional securities, held by such holders as of the
date of filing of such Registration Statement.  The holders shall pay any
additional costs, fees and expenses associated with the inclusion on such
Registration Statement of any of such holders shares of Common Stock or other
securities that are not Registerable Securities that are included on the
Registration Statement.  Notwithstanding the foregoing, if any such managing
underwriter shall advise the Company in writing that, in its opinion, the
distribution of all or a portion of the Common Stock that are not Registrable
Securities requested to be included in the Registration Statement concurrently
with the Registrable Securities being registered by such holders would
materially adversely affect the distribution of such offering then such
additional shares of Common Stock shall be excluded from the Registration
Statement.
<PAGE>

          (k) Upon the written request therefor by any holders of Registrable
Securities, the Company shall include in the Registration Statement filed for a
non-underwritten offering covering any of the Registrable Securities, any other
securities of the Company held by such holders as of the date of filing of such
Registration Statement, including, without limitation, restricted shares of
Common Stock, options, warrants or any other securities convertible into shares
of Common Stock.  The holders shall pay any additional costs, fees and expenses
associated with the inclusion on such Registration Statement of any of such
holders other securities of the Company that are not Registerable Securities
that are included on the Registration Statement.

     7.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SECURITIES.  The following
adjustments apply to the Exercise Price of the Warrants with respect to the
Shares and the number of Shares purchasable upon exercise of the Warrants.

     7.1  COMPUTATION OF ADJUSTED PRICE.  In case the Company shall at any time
after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to its stockholders, then upon such
dividend or distribution the Exercise Price in effect immediately prior to such
dividend or distribution shall forthwith be reduced to a price determined by
dividing:

          (a) an amount equal to the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution multiplied by the
Exercise Price in effect immediately prior to such dividend or distribution, by

          (b) the total number of shares of Common Stock outstanding immediately
after such issuance or sale.

          For the purposes of any computation to be made in accordance with the
provisions of this Section 7.1, the shares of Common Stock issuable by way of a
dividend or other distribution on any shares of Common Stock of the Company
shall be deemed to have been issued immediately after the opening of business on
the date following the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution.

     7.2  SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding shares of Common Stock, the Exercise Price
shall forthwith be proportionately decreased in the case of a subdivision or
increased in the case of a combination.

     7.3  ADJUSTMENT IN NUMBER OF SECURITIES.  Upon each adjustment of the
Exercise Price pursuant to the provisions of this Article 7, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of Shares issuable upon
exercise of the Warrants immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.
<PAGE>

     7.4  RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the Shares immediately prior to
any such events and at an aggregate price equal to the product of (x) the number
of shares of Common Stock issuable upon exercise of the Holders' Warrants and
(y) the Exercise Price in effect immediately prior to the record date for such
reclassification, change, consolidation, merger, sale or conveyance as if such
Holders had exercised the Warrants.

     7.5  DETERMINATION OF OUTSTANDING COMMON STOCK.  The number of shares of
Common Stock at any one time outstanding shall include the aggregate number of
shares issued or issuable upon the exercise of options, rights, warrants and
upon the conversion or exchange of convertible or exchangeable securities.

     7.6  SUBSCRIPTION RIGHTS FOR COMMON STOCK OR OTHER SECURITIES.  In the case
that the Company or an affiliate of the Company shall at any time after the date
hereof and prior to the exercise of all of the Warrants issue any rights to
subscribe for shares of Common Stock or any other securities of the Company or
of such affiliate to all of the shareholders of the Company, the Holders of the
unexercised Warrants shall be entitled, in addition to the shares of Common
Stock or other securities receivable upon the exercise of the Warrants, to
receive at the time such rights as are distributed to the other shareholders of
the Company.

     8.  EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.
<PAGE>

     9.  ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of Shares upon the exercise of the Warrants nor shall it be required
to issue scrip or pay cash in lieu of fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Shares.

     10.  RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized Common Stock, solely for the purpose of issuance upon the exercise of
the Warrants, such number of shares of Common Stock as shall be issuable upon
the exercise thereof.  The Company covenants and agrees that, upon exercise of
the Warrants and payment of the Exercise Price therefor, all Shares issuable
upon such exercise shall be duly and validly issued, fully paid, non-assessable
and not subject to the preemptive rights of any shareholder.  As long as the
Warrants shall be outstanding, the Company shall use its best efforts to cause
all shares of Common Stock issuable upon the exercise of the Warrants to be
listed on or quoted by the Nasdaq National Market, or listed on such national
securities exchanges as requested by the Underwriter.

     11.  NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
stockholder in respect of any meetings of stockholders for the election of
directors or any other matter, or as having any rights whatsoever as a
stockholder of the Company.  If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

          (a) the Company shall take a record of all of the holders of its
     shares of Common Stock for the purpose of entitling them to receive a
     dividend or distribution payable otherwise than in cash, or a cash dividend
     or distribution payable otherwise than out of current or retained earnings,
     as indicated by the accounting treatment of such dividend or distribution
     on the books of the Company; or

          (b) the Company shall offer to all of the holders of its shares of
     Common Stock any additional shares of capital stock of the Company or
     securities convertible into or exchangeable for shares of capital stock of
     the Company, or any option, right or warrant to subscribe therefor; or

          (c) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed; or
<PAGE>

          (d) reclassification or change of the outstanding shares of Common
     Stock (other than a change in par value to no par value, or from no par
     value to par value, or as a result of a subdivision or combination),
     consolidation of the Company with, or merger of the Company into, another
     corporation (other than a consolidation or merger in which the Company is
     the surviving corporation and which does not result in any reclassification
     or change of the shares of outstanding Common Stock, except a change as a
     result of a subdivision or combination of such shares or a change in par
     value, as aforesaid), or a sale or conveyance to another corporation of the
     property of the Company as an entirety is proposed; or

          (e) the Company or an affiliate of the Company shall propose to issue
     any rights to subscribe for shares of Common Stock or any other securities
     of the Company or of such affiliate to all the stockholders of the Company;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable securities or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

     12.  NOTICES.

     All of notices, requests, consents and other communications hereunder shall
be in writing and shall be deemed to have been duly made when delivered, or
mailed by registered or certified mail, return receipt requested:

     Holder as shown on the books of the Company; or

          (b)  If to the Company, to the address set forth in Section 3 of this
     Agreement or to such other address as the Company may designate by notice
     to the Holders.

     13.  SUPPLEMENTS AND AMENDMENTS.

     The Company and Mr. Ledecky may from time to time supplement or amend this
Agreement without the approval of any Holders of Warrant Certificates in order

earlier date when all Warrants have been exercised and all Shares have been

deemed to be a contract made under the laws of the State of Delaware and for all
purposes shall be construed in accordance with the laws of said State.

     17.  BENEFITS OF THIS AGREEMENT.

     Nothing in this Agreement shall be construed to give to any person or
corporation other than the Company and Mr. Ledecky and any other registered
holder or holders of the Warrant Certificates, or Shares any legal or equitable
right, remedy or claim under this Agreement; and this Agreement shall be for the

cash, or by check payable to the order of the Company, or any combination of
cash or check.

     No Warrant may be exercised after 5:00 p.m., Washington, D.C. time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

     The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to in a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the
<PAGE>

Company and the holders (the words "holders" or "holder" meaning the registered
holders or registered holder) of the Warrants.

     The Warrant Agreement provides that upon the occurrence of certain events,
the Exercise Price and/or number of the Company's securities issuable thereupon
may, subject to certain conditions, be adjusted.  In such event, the Company
will, at the request of the holder, issue a new Warrant Certificate evidencing
the adjustment in the Exercise Price and the number and/or type of securities
issuable upon the exercise of the Warrants; provided, however, that the failure
of the Company to issue such new Warrant Certificates shall not in any way
change, alter, or otherwise impair, the rights of the holder as set forth in the
Warrant Agreement.

     Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax, or other governmental charge
imposed in connection therewith.

     Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

     The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

     All terms used in this Warrant Certificate which are defined in the Warrant
Agreement shall have the meanings assigned to them in the Warrant Agreement.

     IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be
duly executed under its corporate seal.
