                             ABOUT THIS PROSPECTUS
 
    This prospectus is part of a registration statement that we filed with the
SEC using a "shelf" registration process. Under this shelf registration process,
the selling noteholders may sell the Notes described in this prospectus in one
or more offerings up to a total dollar amount of $100,000,000.
 
                                  THE COMPANY
 
    We are the leading worldwide provider of vehicle emissions testing equipment
and services. We manufacture equipment that tests vehicle emissions for
compliance with air pollution standards and operate testing programs on behalf
of states and other jurisdictions. We estimate that we have an approximate 35%
share of the domestic market for vehicle emissions testing equipment used by
independent service stations and other service providers in states that have
adopted a "decentralized" program (representing an approximate 30% share of the
domestic market for basic testing equipment and an approximate 48% share of the
domestic market for higher-margin enhanced testing equipment). We also operate,
or are under contract to operate, 14 of the 21 testing programs in the 16 states
that have adopted a centralized program and we operate the only such program in
Canada. In the twelve months ended September 30, 1998, we tested approximately
11.8 million motor vehicles, which represented approximately 70% of the total
North American centralized testing market revenues. As of September 30, 1998, we
had a contractual backlog to provide centralized emissions testing services of
approximately $873 million through 2008.
 
    We sell emissions testing equipment to numerous private sector facilities,
such as service stations, automotive repair shops and dealerships that test
vehicles for compliance with emissions standards. In the emissions testing
industry, such facilities are called decentralized facilities. We manufacture
both "basic" testing systems, that test only a motor vehicle's emissions while
in neutral, and "enhanced" testing systems that test a vehicle's emissions under
simulated driving conditions.
 
    In addition, we test vehicles in high volume, test-only facilities which we
operate on behalf of governmental authorities. Services provided at such
facilities are called centralized testing services. We are the leading provider
of these services in North America and have completed more than 150 million
vehicle tests since 1974. We conduct our centralized testing business under
exclusive, long-term contracts with state, local and other governmental
authorities that typically have an initial term of five to ten years. Pursuant
to these contracts, we generally:
 
    - structure the testing program;
 
    - design a testing facility network;
 
    - select, design and construct individual inspection and test facilities
      with multiple test lanes;
 
    - design and install the required computer network; and
 
    - operate the testing program.
 
    Our unaudited pro forma revenues for the twelve months ended September 30,
1998 which include the results of Environmental Systems Products, Inc. and
Envirotest Systems Corp., are $335.1 million. Fifty percent of these revenues
are from ESP, our equipment business and fifty percent are from Envirotest, our
testing business. Our unaudited pro forma Adjusted EBITDA for the twelve months
ended September 30, 1998 is $114.5 million. Of this amount, $35.6 million is
from our equipment business and $78.9 million is from our testing business. Our
pro forma net income for the twelve months ended September 30, 1998 is $4.1
million. Our unaudited pro forma revenues, Adjusted EBITDA and net income for
the twelve months ended September 30, 1998 give effect to:
 
    - our acquisition of Envirotest; and
 
    - the refinancing related to the acquisition
 
as if these transactions occurred on October 1, 1997.

                        INDUSTRY AND REGULATORY OVERVIEW
 
    Vehicle emissions produce approximately 50% of the ozone air pollution and
nearly all of the carbon monoxide air pollution in metropolitan areas. The EPA
estimates that enhanced emissions testing on motor vehicles is approximately 10
times more cost-effective in reducing air pollution than increasing controls on
stationary pollution sources such as factories and utilities. Consequently, the
EPA has made emissions testing an integral part of its overall effort to reduce
air pollution by ensuring that vehicles meet emissions standards throughout
their lives. Vehicle emissions control requirements began with the passage of
the Clean Air Act in 1970. Since that time, regulations have become
progressively more stringent. The 1990 Amendments, in particular, emphasized the
need for effective emissions control programs and, in 1992, the EPA adopted
regulations that required 181 geographic areas to implement certain types of
emissions control programs by certain dates, depending on the area's population
and its level of air pollution. Today, the EPA has the authority under the Clean
Air Act to withhold non-safety related federal highway funds from states that
fail to implement such mandated programs by prescribed deadlines.
 
    On July 31, 1998, the EPA issued a final study which concluded that more
stringent air quality standards for motor vehicle emissions are needed,
technologically feasible, and cost-effective. We believe that the setting of
such standards will be the most important EPA regulatory initiative affecting
motor vehicles since the passage of the 1990 Amendments. We believe that the EPA
study is likely to result in more stringent standards that will have the effect
of increasing the number of areas which must implement emissions testing
programs and therefore potentially increase the market for our products and
services.
 
    In general, emissions tests are performed either in a centralized program or
in a decentralized program. In a centralized program, vehicle owners take their
vehicles to one of a small number of special centralized facilities to be
tested. These facilities only perform tests; they do not repair vehicles.
Usually, a private contractor licensed by the government operates the
centralized facility. In a decentralized program, vehicle owners take their
vehicles to a service station, automotive repair shop or dealership to be
tested. These decentralized facilities both perform tests and repair vehicles.
The EPA has granted state and local governmental authorities the discretion to
determine how best to establish and operate a network of emissions testing
facilities, including the flexibility to choose either a centralized or a
decentralized program. In 1997, centralized programs in the U.S. and Canada
performed approximately 23.0 million paid tests (36% of the total tests) and
generated approximately $250 million in revenues, while facilities in
decentralized markets into which we sell the testing equipment in the United
States performed approximately 41.7 million tests (64% of the total tests) and
generated approximately $816 million in revenues.
 
    A number of recent international initiatives evidence the increasing
recognition by foreign countries of the hazardous effects of air pollution on
human health and the environment. We believe that foreign countries will
continue to follow the lead of the United States in pollution control and, more
particularly, vehicle emissions testing, and will adopt or upgrade existing
emissions testing programs as an efficient and effective step towards reducing
air pollution. A number of foreign countries have implemented various forms of
mandatory testing programs, including the United Kingdom, Germany, Canada
(certain provinces), Mexico and Japan, and a number of others are considering
developing or expanding mandatory or voluntary testing programs, including
Poland, the Philippines, Brazil, Argentina, and Chile.

                               BUSINESS STRENGTHS
 
    We believe that we have the following competitive advantages:
 
    INDUSTRY LEADER.  We have leading market positions in both the production of
equipment used in the decentralized testing market and in the testing of vehicle
emissions in the centralized testing services market. In 1997, we performed over
three times the number of tests as our closest competitor in the United States
and Canada and received approximately 70% of the total revenues in the
centralized testing market.
 
    STABLE REVENUE SOURCE.  Our centralized vehicle emissions testing services
business provides a stable source of revenues as our testing services contracts
typically have terms ranging from five to ten years.
 
    TECHNOLOGICAL LEADERSHIP AND SUPERIOR CUSTOMER SERVICE.  We believe that we
are the technological leaders in the design and manufacture of vehicle emissions
testing equipment. We have developed proprietary software programs and hold more
than 70 patents on emissions testing and related products. Moreover, ESP
frequently conducts its technology research and product development efforts in
conjunction with governmental authorities. For example, in 1994, the California
BAR awarded ESP two pilot programs for the development of testing standards at a
test facility in Sacramento, California and, in 1995, New Jersey awarded ESP a
study contract to evaluate alternative emissions testing procedures and systems.
In addition, our staff of approximately 182 company-trained direct service
technicians who operate from a network of 10 service hubs throughout the United
States provides superior customer service with an industry leading average
response time for service calls of four to six hours.
 
    EXPERIENCED MANAGEMENT TEAM.  Our management team, which is comprised of
certain of the senior members of the former managements of ESP and Envirotest,
is one of the most experienced in the vehicle emissions testing industry. We
have a combined 40 years of experience in the industry and have demonstrated our
ability to succeed in both the emissions testing equipment business and the
emissions testing services business.
 
                               BUSINESS STRATEGY
 
    Our objective is to maximize our long-term profitability by enhancing our
leading positions in the vehicle emissions testing equipment and testing
services businesses through the following strategies:
 
    EXPAND DOMESTIC BUSINESS.  We intend to expand our share of the existing
markets for emissions testing equipment and centralized testing services. In
addition, we intend to pursue new business as additional jurisdictions require
our equipment and services.
 
    REALIZE BENEFITS FROM ACQUISITION OF ENVIROTEST.  We will integrate the
equipment and testing businesses to take advantage of synergies and economies of
scale in, among other things, engineering, research and development, marketing
and government relations. As a result of the combination of the two businesses,
we expect to save approximately $8.0 to $10.0 million annually, including $4.2
million as a result of the elimination of duplicative management, staff and
facilities. In addition, we believe that the combination of the two businesses
will help us penetrate the developing international market for vehicle emissions
testing because our breadth of experience and expertise will allow us to offer a
broad range of vehicle emissions products and services.
 
    EXTEND TECHNOLOGICAL LEADERSHIP.  By integrating the research and
development groups of ESP and Envirotest, we expect to extend our technological
leadership. We also plan to continue to work with leading government policy
makers, including particularly the California BAR, in developing testing
programs.
 
    EXPAND INTERNATIONAL PRESENCE.  We intend to expand internationally by
offering a broad range of vehicle emissions testing equipment and services to
countries around the world that are likely to adopt emissions testing programs
similar to those adopted in the U.S. We plan to offer our advisory services to
these countries at the early stages of their program development,
 
                                       3

thereby positioning ourselves to become the provider of choice for both
centralized and decentralized testing programs.
 
                                   BACKGROUND
 
    In October 1998, our wholly-owned subsidiary, Environmental Systems
Products, Inc., the leader in the emissions testing equipment business, acquired
all of the outstanding capital stock of Envirotest Systems Corp., a
publicly-owned company and the leader in the emissions testing services
business, for approximately $266.2 million plus the assumption of all its
indebtedness. The combination of ESP and Envirotest has created an emissions
testing industry leader. To finance the acquisition, we undertook a financing
and refinancing of certain indebtedness of Envirotest, ESP and their
subsidiaries in which we:
 
    - repaid $300.3 million of certain existing indebtedness of Envirotest
      (including the repurchase and redemption of all $150.0 million of
      Envirotest's outstanding 9 1/8% Senior Notes due 2001 and all $125.0
      million of Envirotest's outstanding 9 5/8% Senior Subordinated Notes due
      2003);
 
    - paid $12.5 million in debt repurchase premiums;
 
    - repaid all $125.0 million of loans outstanding under ESP's senior secured
      credit facility;
 
    - entered into a new $435.0 million senior secured credit facility;
 
    - raised approximately $179.9 million of additional equity;
 
    - issued $100 million aggregate principal amount of the Notes; and
 
    - paid approximately $43.1 million fees and expenses related to the
      foregoing and the acquisition.
 
    After these transactions and a reorganization of our affiliated companies,
we became a direct, wholly-owned subsidiary of EnviroSystems Corp. and both
Envirotest and ESP became our wholly-owned subsidiaries. Operations are at the
ESP and Envirotest levels and include their direct subsidiaries. We have no
operations or employees at Environmental Systems Products Holdings Inc.
EnviroSystems Corp. has no operations or employees.
 
    We were incorporated in March 1998 under the laws of the State of Delaware.
Our chief executive offices are located at 7 Kripes Road, East Granby,
Connecticut 06026 and our telephone number is (860) 653-0081.

                                               Notes. If we cannot make payments on the
                                               Notes when they are due, the guarantor
                                               subsidiaries must make them instead. Several
                                               of our wholly-owned foreign subsidiaries are
                                               not guarantors of these Notes. Total assets
                                               of these non guarantor subsidiaries are $8.6
                                               million on a pro forma basis.
Ranking......................................  These Notes and the subsidiary guarantees are
                                               senior subordinated debts.
                                               They rank behind all of our and our guarantor
                                               subsidiaries' current and future indebtedness
                                               (other than trade payables), except
                                               indebtedness that expressly provides that it
                                               is not senior to these Notes and the
                                               guarantees.
Optional Redemption..........................  On or after October 31, 2003, we may redeem
                                               some or all of the notes at any time at the
                                               redemption prices listed in the section

Mandatory Offer to Repurchase................  If we sell certain assets or experience
                                               specific kinds of changes of control, we must

                                               subsidiaries to:
                                               - borrow money;
                                               - pay dividends on stock or purchase stock;
                                               - make investments;
                                               - use assets as security in other
                                                 transactions; and
                                               - sell certain assets or merge with or into
                                               other companies.
Use of Proceeds..............................  We used the net proceeds from the initial
                                               offering of these Notes to fund a portion of
                                               the acquisition of Envirotest and the related
                                               transactions.

(5) For purposes of determining the ratio of earnings to fixed charges, earnings
    are defined as income before income taxes, plus fixed charges. Fixed charges
    consist of interest expense on all indebtedness (including amortization of
    deferred debt issuance costs) and that portion of operating lease rental
    expense that is representative of the interest factor. Earnings were
    inadequate to cover fixed charges for the year ended December 31, 1997 by
    $12,648.
 
(6) Represents contractual backlog to provide services through 2008 under
    Envirotest's 15 contracts to provide centralized testing services. Backlog,
    per contract, is calculated by multiplying (i) the average annual test
    volume, (ii) the fee per vehicle tested and (iii) the remaining number of
    years in the contract term, excluding optional extension periods.

                                  RISK FACTORS
 
    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND OTHER
INFORMATION APPEARING IN THIS PROSPECTUS BEFORE BUYING THE NOTES.
 
    THIS PROSPECTUS INCLUDES "FORWARD LOOKING STATEMENTS" WITHIN THE MEANING OF
SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934. THESE FORWARD-LOOKING
STATEMENTS INCLUDE, IN PARTICULAR, THE STATEMENTS ABOUT OUR PLANS, STRATEGIES,
AND PROSPECTS UNDER THE HEADINGS "PROSPECTUS SUMMARY," "MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS," AND "BUSINESS."
ALTHOUGH WE BELIEVE THAT OUR PLANS, INTENTIONS AND EXPECTATIONS REFLECTED IN OR
SUGGESTED BY SUCH FORWARD-LOOKING STATEMENTS ARE REASONABLE, WE MAY NOT ACHIEVE
SUCH PLANS, INTENTIONS OR EXPECTATIONS. IMPORTANT FACTORS THAT COULD CAUSE
ACTUAL RESULTS TO DIFFER MATERIALLY FROM THE FORWARD LOOKING STATEMENTS WE MAKE
IN THIS PROSPECTUS ARE SET FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS. ALL
FORWARD-LOOKING STATEMENTS ATTRIBUTABLE TO US OR PERSONS ACTING ON OUR BEHALF
ARE EXPRESSLY QUALIFIED IN THEIR ENTIRETY BY THE FOLLOWING CAUTIONARY
STATEMENTS. THESE FORWARD LOOKING STATEMENTS INVOLVE RISKS AND UNCERTAINTIES,
AND THE CAUTIONARY STATEMENTS IDENTIFY IMPORTANT FACTORS THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER MATERIALLY FROM THOSE PREDICTED IN ANY SUCH FORWARD LOOKING
STATEMENTS. SUCH FACTORS INCLUDE, BUT ARE NOT LIMITED TO, ADVERSE CHANGES IN
GENERAL ECONOMIC CONDITIONS, INCLUDING ADVERSE CHANGES IN THE SPECIFIC MARKETS
FOR THE COMPANY'S PRODUCTS, ADVERSE BUSINESS CONDITIONS, DECREASED OR LACK OF
GROWTH IN THE CAR INDUSTRY, INCREASED COMPETITION, PRICING PRESSURES, LACK OF
SUCCESS IN TECHNOLOGICAL ADVANCEMENT, RISKS ASSOCIATED WITH FOREIGN OPERATIONS,
RISKS ASSOCIATED WITH THE COMPANY'S EFFORTS TO COMPLY WITH YEAR 2000
REQUIREMENTS, AND OTHER FACTORS.
 
SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR
FINANCIAL HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THESE
NOTES.
 
    We have a significant level of indebtedness. As of September 30, 1998, after
giving pro forma effect to the acquisition of Envirotest and related financings,
we would have had $531.5 million of consolidated indebtedness outstanding and
unused revolving commitments of $50.0 million, less outstanding letters of
credit, under the senior secured credit facility. Although the indenture
governing the Notes and the senior secured credit facility limits our ability to
borrow additional money, under certain circumstances, we would be able to incur
a significant amount of additional indebtedness.
 
    Our level of indebtedness could affect our operations in the following ways:
 
    - we must dedicate a substantial portion of our cash flow from operations to
      the payment of interest expense and principal and, consequently, this cash
      will not be available for other purposes;
 
    - our ability to obtain additional debt financing in the future for working
      capital, capital expenditures, acquisitions, joint ventures or general
      purposes may be limited;
 
    - our level of indebtedness could limit our flexibility in reacting to
      changes in the industry and economic conditions generally, making us more
      vulnerable to a downturn in the industry or the economy in general;
 
    - we may be substantially more leveraged than certain of our competitors,
      placing us at a competitive disadvantage; and
 
    - certain outstanding indebtedness, including outstanding indebtedness under
      the senior secured credit facility, will mature prior to the Notes and is
      secured by substantially all of our assets.
 
ABILITY TO SERVICE INDEBTEDNESS--TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A
SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS
BEYOND OUR CONTROL.
 
    Our ability to pay interest on the Notes and to satisfy other debt
obligations depends upon our future operating performance. Our future operating
performance will be affected by prevailing economic conditions, governmental
regulations (including, particularly, government regulations regarding vehicle
emissions), financial, business and other factors, including factors beyond our
control. We anticipate that
 
                                       13
<PAGE>
our operating cash flow and amounts available under our senior secured credit
facility will cover our operating expenses and will be sufficient to service our
debt. However, we cannot guarantee that these amounts will be sufficient.
 
    We anticipate that at or before maturity we will refinance the Notes if we
can obtain financing. If we are unable to service our indebtedness, we will be
forced to adopt an alternative strategy. Possible alternative strategies
include:
 
    - reducing or delaying capital expenditures;
 
    - selling assets;
 
    - restructuring or refinancing our indebtedness; or
 
    - seeking additional equity capital.
 
    We cannot guarantee that we can effect any of these strategies on
satisfactory terms, if at all. For example, the senior secured credit facility
and the indenture pursuant to which the Notes were issued contain covenants that
restrict our ability to take certain of the foregoing actions, including selling
assets and using the proceeds therefrom.
 
SUBSTANTIAL RESTRICTIONS AND COVENANTS--RESTRICTIONS AND COVENANTS IN OUR DEBT
AGREEMENTS LIMIT OUR ABILITY TO TAKE CERTAIN ACTIONS.
 
    The indenture governing the Notes contains a number of significant
restrictions and covenants. These covenants limit our ability, among other
things, to:
 
    - borrow more money;
 
    - incur liens;
 
    - pay dividends or make certain other restricted payments;
 
    - sell certain assets;
 
    - enter into certain transactions with affiliates; and
 
    - make certain acquisitions.
 
    The indenture also imposes restrictions on the ability of any of our
subsidiaries to:
 
    - pay dividends or make certain payments to us;
 
    - merge or consolidate with any other person; or
 
    - sell, assign, transfer, lease, convey or otherwise dispose of all or
      substantially all of their assets.
 
    In addition, our senior secured credit facility contains other more
restrictive covenants, including covenants that require us to maintain certain
financial ratios. If we are unable to comply with these covenants, there would
be a default under our senior secured credit facility. Such a default would also
result in a default under the indenture governing these Notes. Such defaults, if
not waived, could result in acceleration of our indebtedness and, at worst, our
bankruptcy.
 
HOLDING COMPANY STRUCTURE--OUR STATUS AS A HOLDING COMPANY MAKES US DEPENDENT ON
THE CASH FLOWS OF OUR SUBSIDIARIES TO MEET OUR OBLIGATIONS.
 
    We are a holding company and conduct almost all of our operations through
our subsidiaries. We do not have any significant assets other than the stock of
our subsidiaries. Accordingly, we depend on the cash flows of our subsidiaries
to meet our obligations, including the payment of the principal and interest on
the Notes. In addition our parent company, EnviroSystems is highly leveraged.
While we have not guaranteed
 
                                       14
<PAGE>
EnviroSystems' debt there is an expectation that our operations and those of our
subsidiaries will be able to service the parent company debt.
 
RANKING OF THE NOTES--YOUR RIGHT TO RECEIVE PAYMENTS ON THESE NOTES IS
SUBORDINATE TO ALL SENIOR INDEBTEDNESS OF OUR COMPANY OR THE APPLICABLE
SUBSIDIARY GUARANTOR.
 
    According to the indenture under which the Notes were issued, the payment of
the principal, any premium and interest on the Notes and each subsidiary
guaranty of the Notes is subordinate in right of payment to the prior payment in
full of all senior indebtedness of our company or the applicable subsidiary
guarantor. The senior indebtedness includes our obligations under, and the
subsidiary guarantors' guarantees of our obligations with respect to, our senior
secured credit agreement.
 
    Assuming we had completed the acquisition of Envirotest and the related
transactions on September 30, 1998, our senior indebtedness outstanding would
have been approximately $438.1 million and each of the subsidiary guarantors
would have guaranteed substantially all of such senior indebtedness on a senior
basis. Although the indenture governing these Notes and the senior secured
credit facility limit the amount of money we and the subsidiary guarantors may
borrow, we and the subsidiary guarantors may borrow a significant amount of
additional money under certain circumstances. In addition, this money may be
senior indebtedness.
 
    Holders of senior indebtedness will be able to prevent payment on the Notes
or the related subsidiary guarantee of the Notes:
 
    - in the event of our bankruptcy, liquidation or reorganization or that of
      any subsidiary guarantor;
 
    - if there is a payment default under certain senior indebtedness; and
 
    - if there are certain non-payment defaults under certain senior
      indebtedness.
 
FRAUDULENT TRANSFER CONSIDERATIONS--A COURT MAY VOID THE GUARANTEES OF OUR
SUBSIDIARIES.
 
    The indenture obligations of a subsidiary guarantor may be reviewed under
the appropriate fraudulent transfer or similar laws upon bankruptcy or other
financial difficulty. Under these laws a court may rule that the guarantee
obligations of the unpaid creditor, a representative of creditors of the
subsidiary guarantor or any debtor in possession are void, and the court may
direct the return of any amounts paid to holders of the Notes. A court may find
that at the time guarantee obligations were incurred or assets were pledged the
unpaid creditor or a representative of creditors of the subsidiary guarantor
(I.E., a trustee in bankruptcy):
 
    - received less than fair consideration or reasonably equivalent value in
      exchange or as consideration to enter into its subsidiary guarantee or to
      pledge its assets to secure its obligations under its subsidiary
      guarantee; and
 
    - either:
 
     --  was insolvent;
 
     --  became insolvent;
 
     --  engaged in or was about to engage in a business or transaction for
        which its remaining unencumbered assets constituted unreasonably small
        capital; or
 
     --  intended to incur, or believed or reasonably should have believed, that
        it would incur debts unable to be satisfied.
 
    Such court could void such obligations under the subsidiary's guarantee and
direct the return of any amounts paid with respect thereto or take other action
detrimental to the holders of the Notes. Moreover, regardless of the factors
identified above, a court could take action if it found that the guarantee was
entered into with actual intent to hinder, delay, or defraud creditors.
 
                                       15
<PAGE>
    The measure of insolvency varies depending on the law of the jurisdiction
being applied. Generally, however, an entity is insolvent if the sum of its
debts (including contingent or unliquidated debts) is greater than the fair
value of all its property or if the present fair salable value of its assets is
less than the amounts owed on its existing debts as they become due. We cannot
guarantee which standard a court would apply to determine whether a subsidiary
guarantor was "insolvent" upon either consummation of the sale of the Notes or
upon the incurrence of the subsidiary guarantees. We also cannot guarantee that
a court will not decide that one or more subsidiary guarantors was insolvent as
a result of the foregoing.
 
DEPENDENCE ON GOVERNMENT REGULATION--OUR INDUSTRY IS HIGHLY REGULATED AND
CHANGES IN SUCH REGULATIONS MAY ADVERSELY AFFECT OUR BUSINESS.
 
    Our business substantially depends upon Federal and state legislation and
regulations mandating air pollution controls. The vehicle emissions testing
industry in the U.S. has developed in response to the Clean Air Act and related
EPA regulations. The EPA is currently evaluating the need for more stringent
emissions standards for motor vehicles. We cannot assure you that additional
Federal or state legislation, or changes in regulatory requirements (including
the EPA's guidance on "clean screening" methods if finalized in its current
form) would not, directly or indirectly, have a material adverse effect on the
vehicle emissions testing industry.
 
    Additionally, the growth of our international business, which we expect to
constitute a significant portion of our business in coming years, depends
largely upon the adoption of foreign air pollution control legislation and
related regulations requiring or encouraging vehicle emissions testing
development in those countries. Although a number of countries in Europe, Asia
and Latin America have passed or are considering such legislation, and a limited
number of countries, including the United Kingdom, Germany, Canada (certain
provinces), Mexico and Japan, have mandatory vehicle emissions testing, these
countries may not enact and enforce, or continue to enforce, as the case may be,
the necessary legislation and regulations. Any failure of these and other
foreign countries to implement air pollution control legislation that requires
or encourages vehicle emissions testing could limit our international expansion
plans, which could have a material adverse effect on our business, financial
condition and results of operations.
 
DEPENDENCE ON INTELLECTUAL PROPERTY--WE USE A SIGNIFICANT AMOUNT OF INTELLECTUAL
PROPERTY IN OUR BUSINESS. IF WE ARE UNABLE TO PROTECT THIS INTELLECTUAL
PROPERTY, OUR BUSINESS MAY BE ADVERSELY AFFECTED.
 
    Our success is dependent on our ability to protect our proprietary rights.
We employ a combination of the following methods to protect these rights:
 
    - patents;
 
    - trade secrets;
 
    - copyright and trademark laws;
 
    - license agreements;
 
    - non-compete agreements;
 
    - nondisclosure agreements;
 
    - assignment of invention and other contractual provisions; and
 
    - various security measures.
 
    We cannot guarantee that the legal protections afforded to, or the
precautions taken by, our company or our third-party licensors will be adequate
to prevent misappropriation of our respective proprietary rights. We generally
enter into confidentiality agreements with our employees, which typically
control access to, disclosure of and ownership of, intellectual property
developed during the term of employment with us. However, these contractual
protections do not preclude independent third-parties from developing
functionally equivalent or superior technologies, products, or professional
services. Any infringement
 
                                       16
<PAGE>
or misappropriation of our proprietary rights, or those of our third-party
licensors, could have a material adverse effect on our business, financial
condition, and results of operations.
 
    In the future, litigation may be necessary to enforce and protect our
patents, trade secrets, copyrights and other intellectual property or
proprietary rights. We may also be subject to litigation to defend against
claimed infringement of, or to determine the scope and validity of, the
intellectual property or proprietary rights of others. We are not currently
aware that our products, trademarks, or other proprietary rights infringe upon
the proprietary rights of any third parties. However, we cannot assure you that
third parties will not assert infringement claims against us which may result in
a material adverse effect on our business, financial condition, and results of
operations. Any litigation involving our use of technology may result in
substantial cost to us and may divert management's attention from operations.
Either could also have a material adverse effect on our business, financial
condition and results of operations. A negative outcome in litigation could:
 
    - result in our loss of the rights to use the proprietary rights (or the
      exclusivity of our rights therein);
 
    - subject us to significant liabilities;
 
    - require us to seek licenses from third parties; or
 
    - prevent us from selling our products.
 
    - any one of these outcomes could have a material adverse effect on our
      business, financial condition and results of operations.
 
YEAR 2000 RISKS--ALTHOUGH WE EXPECT TO BE YEAR 2000 COMPLIANT, WE ARE NOT SO AT
THIS TIME. YEAR 2000 ISSUES MAY NEGATIVELY AFFECT US.
 
    The Company has a Year 2000 project designed to identify and assess the
risks associated with its information systems, products, operations and
infrastructure, suppliers and customers that are not Year 2000 compliant and to
develop, implement and test remediation and contingency plans to mitigate these
risks.
 
    As we continue our Year 2000 project, we may discover additional Year 2000
problems, we may not be able to develop, implement or test remediation or
contingency plans or we may find that the costs of these activities exceed
current expectations and become material. Even if we, in a timely manner,
complete all of our assessments, identify and test remediation plans believed to
be adequate, and develop contingency plans believed to be adequate, some
problems may not be identified or corrected in time to prevent material adverse
consequences to us.
 
MATURATION OF EMISSIONS TESTING PRODUCTS MARKET--WE EXPECT THE DOMESTIC MARKET
FOR EMISSIONS TESTING EQUIPMENT TO DECLINE SIGNIFICANTLY IN APPROXIMATELY THREE
YEARS.
 
    In the twelve months ended September 30, 1998, assuming we completed the
acquisition of Envirotest and the related transactions on September 30, 1998, we
would have obtained approximately 50% of our revenues from sales of our
equipment to decentralized facilities and after-sales services in states with
decentralized programs. We expect the domestic market for equipment used in
states with decentralized programs to continue to expand for approximately the
next three years as additional states and municipalities are either required to
or elect to implement decentralized programs and/or convert basic idle testing
systems to enhanced programs which test emissions under simulated driving
conditions. Thereafter, however, we expect the size of the domestic market to
decline significantly as a result of most states with large vehicle populations
having already implemented programs. Although we expect revenues from sales of
our equipment in international markets and revenues from our domestic
centralized vehicle emissions testing business to continue to grow in the
future, we cannot assure you that growth in these markets will be sufficient to
offset any decline we are likely to suffer in our domestic emissions equipment
business.
 
                                       17
<PAGE>
ABILITY TO MANAGE AND SUSTAIN GROWTH AND ASSOCIATED RISKS--MANAGING THE GROWTH
RESULTING FROM THE ACQUISITION OF ENVIROTEST COULD POSE DIFFICULTIES WHICH MAY
HAVE A MATERIAL ADVERSE EFFECT ON US.
 
    Our growth has resulted in new and increased responsibilities for our
management. The process of integrating the businesses of Envirotest with that of
ESP may result in unforeseen operating difficulties and may require substantial
attention from members of our senior management. We cannot assure you that we
will be able to integrate successfully the operations of these businesses.
 
    We intend to realize cost savings by rationalizing our operations. As a
result of our acquisition of Envirotest, we expect to reduce our operating
expenses by eliminating duplicative management, staff and facilities, and other
cost efficiencies. Although we believe that our strategies are reasonable, we
cannot assure you that we will be able to implement our plans on schedule. When
implementing these initiatives, we could encounter unanticipated problems, and
there is no guarantee that we will attain our goal of reducing our operating
expenses. Finally, we note that our plans will require substantial attention
from members of our management, which may limit the amount of time they can
devote to our day-to-day operations.
 
DEPENDENCE ON SIGNIFICANT CONTRACTS--OUR CENTRALIZED TESTING BUSINESS IS
DEPENDENT ON 14 CONTRACTS FOR ITS REVENUE.
 
    In the twelve months ended September 30, 1998, assuming we completed the
acquisition of Envirotest and the related transactions on September 30, 1998, we
would have obtained approximately 50% of our revenues from Envirotest's
emissions testing business. For the twelve months ended September 30, 1998,
approximately 99% of Envirotest's contract revenues were derived from its 14
emissions testing contracts with governmental authorities. The termination, or
the Company's failure to obtain the renewal, of any of our significant emissions
testing contracts could have a material adverse effect on our business,
financial condition or results of operations.
 
COMPETITION--INCREASED COMPETITION IN THE FUTURE COULD HAVE A MATERIAL ADVERSE
EFFECT ON US.
 
    The vehicle emissions testing industry is highly competitive and is
characterized by changing air pollution control standards, evolving customer
needs, and rapid technological changes. Our success depends upon our ability to
compete in the areas of quality, price, ease of use, safety and customer
service. We have less potential financial resources than our competitors. We
operate in a rapidly changing technological environment where quick response to
new technologies and other competitive forces is necessary to compete
successfully. Our success depends in part upon our ability:
 
    - to enhance further the products and services we offer;
 
    - to develop or acquire new products and technologies that incorporate
      technological advances;
 
    - to keep pace with evolving vehicle emissions industry standards (which
      vary from jurisdiction to jurisdiction); and
 
    - to respond to changing customer requirements.
 
    If we are unable to develop and introduce new products, services or
enhancements in a timely manner in response to changing market conditions,
governmental regulation or customer requirements, our business, financial
condition, and results of operations are likely to be materially adversely
affected.
 
DEPENDENCE ON KEY PERSONNEL--OUR SUCCESS WILL CONTINUE TO DEPEND TO A
SIGNIFICANT EXTENT ON OUR EXECUTIVES AND OTHER KEY MANAGEMENT PERSONNEL.
 
    Our success will continue to depend to a significant extent on our current
executive officers and key employees as well as our ability to attract and
retain highly qualified experienced electrical, software, mechanical and design
engineers, service technicians and marketing, sales personnel and key personnel
to expand our international operations. We may not be able to retain our
executive officers and key personnel
 
                                       18
<PAGE>
or attract highly qualified management in the future. Our failure to retain the
services of key personnel could have a material adverse effect on us. Although
we have non-competition agreements with certain key personnel, courts are
sometimes reluctant to enforce these agreements.
 
CONTROL BY PRINCIPAL STOCKHOLDERS--ALCHEMY INVESTMENT PLAN WILL OWN ENOUGH OF
OUR PARENT COMPANY'S STOCK TO INDIRECTLY CONTROL OUR AFFAIRS AND THOSE OF OUR
SUBSIDIARIES.
 
    Alchemy Investment Plan, an investment group managed by Alchemy Partners,
owns a substantial majority of the voting stock of EnviroSystems Corp., our sole
stockholder. Consequently, they will indirectly control all matters at our
Company and our subsidiaries requiring stockholder approval, including election
of the Board of Directors and approval of significant corporate transactions. We
cannot assure you that Alchemy Investment Plan will not exercise its control
over EnviroSystems Corp. in a manner detrimental to your interests.
 
INABILITY TO REPURCHASE NOTES UPON A CHANGE OF CONTROL--WE MAY NOT HAVE THE
ABILITY TO RAISE THE NECESSARY FUNDS TO PAY FOR THE NOTES SHOULD WE BE REQUIRED
TO REPURCHASE.
 
    Upon the occurrence of certain kinds of change of control events, as defined
in the indenture governing the Notes, we will be required to make an offer to
repurchase the Notes at 101% of their principal amount, plus accrued interest.
If a change of control were to occur, we may not have sufficient funds to pay
the purchase price for all the Notes that we might be required to repurchase.
Additionally, in the event of a change of control, we could be prohibited under
the terms of our senior secured credit facility or indenture from paying the
required purchase price for all the Notes.
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES, RESTRICTIONS ON RESALES--YOU CANNOT BE
SURE THAT AN ACTIVE TRADING MARKET WILL DEVELOP FOR THESE NOTES.
 
    We do not intend to apply for listing or quotation of the Notes on any
exchange. The Notes are, however, eligible for trading in PORTAL. Credit Suisse
First Boston Corporation has advised us that they intend to make a market in the
Notes, subject to the limits imposed by the securities laws. However, they are
not obligated to do so, and they may discontinue any market making at any time
without notice. Therefore, we do not know the extent to which investor interest
will lead to the development of a trading market or how liquid that market might
be.
 
    Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of such
securities. The market for the Notes may be subjected to similar disruptions.
Any such disruptions may have an adverse effect on the Note holders.
 
ORIGINAL ISSUE DISCOUNT AND MARKET DISCOUNT
 
    Although not free from doubt, the Notes should be considered to have been
issued with original issue discount when placed with the selling noteholders
pursuant to a private placement. In the case of a holder purchasing from a
selling noteholder, original issue discount will accrue from the purchase date
of the Notes. In such case, besides including stated interest in income in
accordance with its usual method of tax accounting, a holder subject to United
States federal income tax with respect to a Note generally will be required to
include original issue discount in gross income for United States federal income
tax purposes in advance of the cash payments to which the income is
attributable. For a more detailed discussion of the United States federal income
tax consequences to the holders of the purchase, ownership and disposition of
the Notes, see "Certain United States Federal Tax Consequences."

                           SOURCES AND USES OF FUNDS
 
    The gross proceeds of the private sale of the Notes were approximately
$100.0 million. Our company used the proceeds of the private sale of the Notes,
together with additional equity, $385.0 million of borrowings under the senior
secured credit facility and $84.4 million of available cash, to consummate the
acquisition of Envirotest and the related transactions.
 
    The following table presents the sources and uses of funds for the
acquisition of Envirotest and the related transactions:

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
The following unaudited pro forma combined financial statements (the "Pro Forma
Financial Statements") are based on the historical consolidated financial
statements of ESP and Envirotest included elsewhere in this prospectus or
derived from unaudited information not contained in this Prospectus, adjusted to
give effect to the acquisition of Envirotest and the related transactions.
 
    The Unaudited Pro Forma Combined Statement of Operations and other financial
data for the year ended December 31, 1997 give effect to the acquisition of
Envirotest and the related transactions as if they occurred on January 1, 1997.
The Unaudited Pro Forma Combined Statement of Operations and other financial
data for the twelve months ended September 30, 1998 give effect to the
acquisition of Envirotest and the related transactions as if they occurred on
October 1, 1997. The Unaudited Pro Forma Combined Statement of Operations and
other financial data for the nine months ended September 30, 1998 give effect to
the acquisition of Envirotest and the related transactions as if they occurred
on January 1, 1998. The Unaudited Pro Forma Combined Balance Sheet gives effect
to the acquisition of Envirotest and the related transactions as if they had
occurred as of September 30, 1998.
 
    The historical information of ESP for the year ended December 31, 1997 is
derived from the audited financial statements of ESP for the year ended December
31, 1997. The historical information of Envirotest for the year ended December
31, 1997 is based on unaudited quarterly information for the calendar quarters
in 1997. The historical information of ESP for the twelve months ended September
30, 1998 is based on unaudited quarterly information for the last calendar
quarter of 1997 and the first three calendar quarters of 1998. The historical
information of Envirotest for the twelve months ended September 30, 1998 is
derived from the audited financial statements of Envirotest for the year ended
September 30, 1998. The historical information of ESP for the nine months ended
September 30, 1998 is based on unaudited quarterly information for the calendar
quarters of 1998. The historical information of Envirotest for the nine months
ended September 30, 1998 is based on unaudited quarterly information for the
calendar quarters of 1998.
 
    The acquisition of Envirotest and the related transactions adjustments are
described in the accompanying notes. These related adjustments are based upon
available information and certain assumptions that management believes are
reasonable. The Pro Forma Financial Statements do not indicate what our results
of operations or financial condition would have been had the acquisition of
Envirotest and the related transactions in fact occurred on such dates; nor do
they project our results of operations or financial condition for the future.
You should read the Pro Forma Financial Statements in conjunction with the
historical consolidated financial statements of ESP and Envirotest and the notes
thereto included elsewhere in this prospectus. You should also read the
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" section of this prospectus.
 
    We accounted for our acquisition of Envirotest using the purchase method of
accounting. We allocated the total purchase price for such acquisition to the
tangible and identifiable intangible assets and liabilities of the acquired
business based upon our preliminary estimates of their fair value with the
remainder of the purchase price allocated to goodwill. We engaged an independent
valuation firm to assist us allocate the purchase price. Our allocation of
purchase price for the Envirotest acquisition is based on the preliminary
findings of the valuation firm and subject to revision when we obtain additional
information concerning asset and liability valuations. Consequently, the amounts
reflected in the pro forma financial statements are subject to change, but we do
not believe the final amounts will differ substantially.

           The interest rate is LIBOR plus 3.25% on Term Loan A and LIBOR plus 4.00% on
           Term Loan B through March 31, 1999, after which the interest rate could range
           from LIBOR plus 2.25% to LIBOR plus 4.00% depending on the Company's financial
           ratios. (The Senior Secured Credit Facility also permits the Company to choose
           an interest rate based on the prime lending rate of Credit Suisse First Boston
           plus a margin or the federal funds rate plus a margin). The pro forma interest
           expense has been calculated based on the LIBOR rate at September 30, 1998 plus
           3.25% on Term Loan A and 4.00% on Term Loan B.
 
           The Company estimates that an increase or decrease in interest rates on the
           Term Loan A and Term Loan B debt of 1/8% would increase or decrease annual
           interest expense by approximately $480.
 
(8)        Income tax expense adjustment related to the effects of the pro forma
           adjustments based upon an assumed composite income tax rate of 41% applied to

           The interest rate is LIBOR plus 3.25% on Term Loan A and LIBOR plus 4.00% on
           Term Loan B through March 31, 1999, after which the interest rate could range
           from LIBOR plus 2.25% to LIBOR plus 4.00% depending on the Company's financial
           ratios. (The Senior Secured Credit Facility also permits the Company to choose
           an interest rate based on the prime lending rate of Credit Suisse First Boston
           plus a margin or the federal funds rate plus a margin). The pro forma interest
           expense has been calculated based on the LIBOR rate at September 30, 1998 plus
           3.25% on Term Loan A and 4.00% on Term Loan B.
 
           The Company estimates that an increase or decrease in interest rates on the
           Term Loan A and Term Loan B debt of 1/8% would increase or decrease annual
           interest expense by approximately $480.
 
(7)        Income tax expense adjustment related to the effects of the pro forma
           adjustments based upon an assumed composite income tax rate of 41% applied to
           pro forma income (loss) before income taxes and extraordinary item adjusted

(8)        For purposes of determining the ratio of earnings to fixed charges, earnings
           are defined as income before income taxes, plus fixed charges. Fixed charges
           consist of interest expense on all indebtedness (including amortization of
           deferred debt issuance costs) and that portion of operating lease rental
           expense that is representative of the interest factor.

           The interest rate is LIBOR plus 3.25% on Term Loan A and LIBOR plus 4.00% on
           Term Loan B through March 31, 1999, after which the interest rate could range
           from LIBOR plus 2.25% to LIBOR plus 4.00% depending on the Company's
           financial ratios. (The Senior Secured Credit Facility also permits the
           Company to choose an interest rate based on the prime lending rate of Credit
           Suisse First Boston plus a margin or the federal funds rate plus a margin).
           The pro forma interest expense has been calculated based on the LIBOR rate at
           September 30, 1998 plus 3.25% on Term Loan A and 4.00% on Term Loan B.
 
           The Company estimates that an increase or decrease in interest rates on the
           Term Loan A and Term Loan B debt of 1/8% would increase or decrease annual
           interest expense by approximately $480.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    YOU SHOULD READ THE FOLLOWING DISCUSSIONS ALONG WITH THE CONSOLIDATED
FINANCIAL STATEMENTS OF ESP AND ENVIROTEST APPEARING ELSEWHERE IN THIS
PROSPECTUS. FOR INFORMATION REGARDING THE PRO FORMA FINANCIAL CONDITION OF THE
COMPANY, SEE "ENVIRONMENTAL SYSTEMS PRODUCTS HOLDINGS INC. UNAUDITED PRO FORMA
FINANCIAL STATEMENTS" INCLUDED IN THIS PROSPECTUS.
 
OVERVIEW
 
    Both ESP and Envirotest originated from United Technologies Corporation, an
innovator in emissions testing technology. ESP was formed in 1989 in connection
with a management buyout of the decentralized testing division of United
Technologies. In April 1996, a wholly-owned subsidiary of Wellman plc, a then
publicly incorporated United Kingdom company, acquired ESP. Newmall plc, an
entity controlled by Alchemy that is now the indirect parent of ESP and its
subsidiaries, recently acquired Wellman plc. Envirotest has operated in the
vehicle emissions testing business since 1974 through its predecessor company,
Hamilton Test Systems, Inc., which was acquired from United Technologies in a
management buyout in 1990. Hamilton Test Systems commenced operations in the
emissions testing business in 1974 with the award of the contract for the
Arizona emissions testing program, the first centralized, test-only program in
the United States. Subsequently, Envirotest acquired Envirotest Technologies,
Inc., in 1992 from Electronic Data Systems, adding an additional five emissions
testing programs shortly before adoption of the rules and regulations by the EPA
implementing the 1990 amendments to the Clean Air Act. In 1996, Envirotest
acquired two additional emissions testing programs from System Control, Inc., as
well as retaining the senior management team.
 
ENVIRONMENTAL SYSTEMS PRODUCTS, INC.
 
    ESP derives its revenues both in the domestic and international markets from
the sale of its emissions testing equipment and from servicing fees for repairs
and maintenance of those systems. ESP's emissions testing equipment business has
been characterized by long lead times for sales cycles and relatively
predictable sales, primarily because states and municipalities in the United
States that have implemented decentralized emissions testing programs have
generally each adopted a plan and target date for implementation which have
typically been publicly announced 12 to 24 months in advance. This causes surges
in demand from a state for emissions testing equipment generally four to six
months prior to the scheduled implementation date. ESP's rapid growth in the
last two quarters of 1997 and the first three quarters of 1998, for example, is
primarily the result of the implementation of enhanced emissions testing
programs in certain metropolitan areas with large vehicle populations (including
Los Angeles, Sacramento and San Diego, California) and a two-phase
basic/enhanced program in New York City and surrounding areas and due to the
implementation of an emissions testing program in Salt Lake City, Utah, with
respect to which ESP is the exclusive provider of testing systems. Following
implementation of a decentralized emissions testing program, ESP continues to
derive revenues in such jurisdiction from residual sales and, after a one-year
warranty period, from equipment servicing.
 
    ESP conducts its current international operations directly and through its
principal wholly-owned subsidiaries, Environmental Systems Products de Mexico,
S.A. de C.V., which does business in Mexico, ESP Abgas- und Umwelt analysen
GmbH, which does business in Germany, and Environmental Systems Products,
Canada, Inc., which does business in Canada.
 
    Technological advances in the emissions testing industry have led to the
development of enhanced emissions testing systems which have higher average
sales prices and gross margins. While basic emissions testing systems, which
only test an automobile's emissions while in neutral, sell for approximately
$12,000, enhanced emissions testing systems, which test an automobile's
emissions under simulated driving conditions, sell for approximately $35,000 to
$40,000. While five states currently require the use of the enhanced
 
                                       38
<PAGE>
emissions testing systems, Massachusetts and New Jersey have also publicly
indicated their intention to require such systems in the future and we believe
that more and more states are likely to require the use of these systems. Demand
for enhanced systems, in particular, has contributed to ESP's increase in
revenues and profits.
 
    ESP outsources the manufacture of substantially all of its subassemblies to
third party suppliers that produce the components pursuant to ESP's proprietary
specifications. The emissions testing systems are assembled, integrated, and
tested by ESP and then shipped to customers based on order commitments. This
outsourcing strategy enables ESP to focus its financial resources on product and
technology development and enhancement, by allowing ESP to maintain a low supply
of inventory and to minimize production cost. Therefore, cost of revenues
primarily consists of purchased components and subassemblies for use in ESP's
products, as well as costs associated with assembly, integration, and testing,
and associated overheads.
 
    The following table sets forth certain income and expense items from ESP's
historical consolidated statements of operations expressed as a percentage of
revenues for the periods indicated.

NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO THE NINE MONTHS ENDED
  SEPTEMBER 30, 1997
 
    REVENUES.  Revenues for the nine months ended September 30, 1998 increased
by $63.9 million, or 136.5%, to $110.7 million from $46.8 million for the nine
months ended September 30, 1997. This increase was primarily attributable to
increased domestic sales of equipment as a result of the implementation of
enhanced testing programs in California and northern Virginia and implementation
of a unique two-phase basic/enhanced program in New York. In addition, ESP was
the sole equipment provider of approximately 300 testing systems for Salt Lake
City, Utah's testing program, the sales of which were recorded during the first
nine months of 1998. The increase in revenues also was due to the fact that
during the first nine months of 1998 ESP sold an increased number of enhanced
testing systems, which sell for approximately three times the price of basic
systems, as a result of the implementation of the enhanced testing programs in
California, New York, Utah and northern Virginia. While the implementation of
testing programs can vary significantly from quarter to quarter, the large
number of enhanced testing programs that were implemented during the first nine
months of 1998 is not indicative of the normal level of state testing program
implementation in any particular quarter. Accordingly, ESP does not expect its
revenues to increase at this rate in future periods.

    GROSS PROFIT.  Gross profit for the nine months ended September 30, 1998
increased by $14.4 million, or 82.8%, to $31.8 million from $17.4 million for
the nine months ended September 30, 1997. This increase was primarily
attributable to increased revenues in the first nine months of 1998. As a
percentage of revenues, gross profit decreased to 28.7% for the nine months
ended September 30, 1998 from 37.2% for the nine months ended September 30,
1997. The decrease in gross profit as a percentage of revenues for the nine
months ended September 30, 1998 was attributable to a number of factors,
including a substantial decrease in service revenues. Service revenues declined
because of the implementation of the unusually large number of enhanced testing
programs which resulted in existing basic testing systems that were serviced
under ESP service contracts being replaced with new, enhanced testing systems
covered by one to two-year warranties. Service revenues as a percentage of total
revenues decreased from approximately 24.3% for the nine months ended September
30, 1997 to approximately 7.2% for the nine months ended September 30, 1998. As
a result of the limited service contract activity, gross margin percentage for
service revenues for the nine months ended September 30, 1997 was approximately
42.8% and was approximately 14.8% for the nine months ended September 30, 1998.
Other factors that contributed to the decrease in gross profit include
recognition of the $2.4 million inventory step-up resulting from the Alchemy
acquisition, an aggressive pricing strategy to obtain the exclusive right to
provide enhanced testing systems to emissions testing facilities located in Salt
Lake City, Utah and additional expenses, including overtime and temporary labor
costs and express freight charges, that ESP incurred in order to fulfill the
large volume of customer orders.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses for the nine months ended September 30, 1998 increased
by $6.6 million, or 67.3%, to $16.4 million from $9.8 million for the nine
months ended September 30, 1997. Selling expenses consist primarily of salaries,
commissions and benefits paid to direct and indirect sales and marketing
personnel, professional service fees, travel related to the sales process, trade
shows, advertising and promotional expenses and other selling and distribution
costs. Selling expenses for the nine months ended September 30, 1998 increased
by $3.3 million or 91.7% to $6.9 million from $3.6 million for the nine months
ended September 30, 1997. This increase was primarily attributable to increased
compensation and benefits paid to personnel and additions necessary to promote
sales efforts, particularly in California and New York. Administrative expenses
include compensation and benefits to administrative personnel, including
directors, officers, facilities, insurance and other general expenses.
Administrative expenses for the nine months ended September 30, 1998 increased
by $2.9 million or 63.0% to $7.5 million from $4.6 million for the nine months
ended September 30, 1997. This increase was primarily attributable to an
increase in performance bonuses payable to certain members of management and
amortization of intangibles resulting from the Alchemy acquisition. Engineering
expenses consist primarily of compensation, benefits and associated costs
relating to research and development personnel, occupancy costs and new product
and process development costs. Engineering expenses for the nine months ended
September 30, 1998 increased by $0.4 million or 25.0% to $2.0 million from $1.6
million for the nine months needed September 30, 1997. This increase was
primarily attributable to increased compensation and benefits paid to additional
personnel and independent contractors in connection with the development of, and
enhancements to, testing systems sold in states that implemented testing
programs during such period. As a percentage of revenues, selling, general and
administrative expenses decreased to 14.8% for the nine months ended September
30, 1998 from 21.0% for the nine months ended September 30, 1997.
 
    INCOME FROM OPERATIONS.  As a result of the above factors, income from
operations rose 103.9% from $7.6 million in the nine months ended September 30,
1997 to $15.5 million in the nine months ended September 30, 1998, which
constituted 16.2% and 13.9% of sales, respectively, for such years.
 
    INTEREST EXPENSE.  Interest expense consists of interest expense paid on
ESP's debt. Interest expense for the nine months ended September 30, 1998
increased by $5.1 million to $5.2 million from $0.1 million for the nine months
ended September 30, 1997. This increase was primarily attributable to increased
interest expense associated with outstanding debt obligations.
 
                                       40
<PAGE>
    OTHER INCOME (EXPENSE).  Other income (expense) consists primarily of
foreign exchange losses. Other expense for the nine months ended September 30,
1998 decreased by $0.5 million to ($0.4) million from $0.1 for the nine months
ended September 30, 1997. This decrease was primarily attributable to increased
foreign exchange losses due to the devaluation of the Mexican peso to the U.S.
dollar.
 
    PROVISION FOR INCOME TAXES.  Provision for income taxes for the nine months
ended September 30, 1998 increased by $2.5 million or 83.3%, to $5.5 million
from $3.0 million for the nine months ended September 30, 1997, resulting in an
effective tax rate of 56.7% and 39.4% for the nine months ended September 30,
1998 and September 30, 1997, respectively. The increase over the federal
statutory rate of 35% is a result of taxes on ESP's foreign operations,
inclusion of state income taxes and goodwill associated with the acquisition of
ESP by Newmall which is not tax deductible.
 
    NET INCOME.  As a result of the above factors, net income declined 8.7%,
from $4.6 million in the nine months ended September 30, 1997 to $4.2 million
for the nine months ended September 30, 1998, which constituted 9.7% and 3.8% of
sales, respectively, for such periods.
 
FISCAL YEAR ENDED DECEMBER 31, 1997 COMPARED TO FISCAL YEAR ENDED DECEMBER 31,
  1996
 
    REVENUES.  Revenues for fiscal 1997 increased by $70.3 million, or 218.3%,
to $102.5 million from $32.2 million for fiscal 1996. Approximately $66.5
million of this increase was attributable to increased domestic sales of
equipment as a result of the implementation of enhanced emissions testing
programs in California, Pennsylvania (Philadelphia) and northern Virginia, phase
I of a two-phase, basic/enhanced emissions testing program in New York and a
basic emissions testing program in Pennsylvania (Pittsburgh), along with
residual sales in Texas and Georgia. The remaining $3.8 million increase was due
primarily to increased international sales.
 
    GROSS PROFIT.  Gross profit for fiscal 1997 increased by $23.5 million, or
182.2%, to $36.4 million from $12.9 million for fiscal 1996. This increase was
primarily attributable to increased domestic sales. As a percentage of revenues,
gross profit decreased to 35.5% for fiscal 1997 from 39.9% for fiscal 1996. The
decrease in gross profit as a percentage of revenues was primarily attributable
to a substantial decrease in service revenues and to high gross profit margins
on certain equipment upgrades that were sold in California during fiscal 1996.
Service revenues declined because of implementation during fiscal 1997 of the
unusually large number of enhanced emissions testing programs which resulted in
existing basic testing systems that were serviced under ESP service contracts
being replaced with new, enhanced testing systems that were covered by one to
two-year warranties.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses for fiscal 1997 increased by $8.8 million, or 96.7%, to
$17.9 million from $9.1 million for fiscal 1996. Selling expenses for fiscal
1997 increased by $6.3 million or 370.6% to $8.0 million from $1.7 million for
fiscal 1996. This increase was primarily attributable to increased salaries,
commissions and benefits paid to new personnel added in order to promote sales
efforts in California, Pennsylvania, New York and Virginia. Administrative
expenses for fiscal 1997 increased by $1.9 million or 33.3% to $7.6 million from
$5.7 for fiscal 1996. This increase was primarily attributable to an increase in
performance bonuses payable to certain members of management, offset by a
decrease in legal, accounting and other professional fees and bad debt expense.
Engineering expenses for fiscal 1997 increased by $0.6 million or 35.3% to $2.3
million from $1.7 million for fiscal 1996. This increase was primarily
attributable to increased compensation and benefits paid to additional personnel
and independent contractors in connection with the development of, and
enhancements to, testing equipment sold in states that implemented emissions
testing programs during 1997. As a percentage of revenues, selling, general and
administrative expenses decreased to 17.4% for fiscal 1997 from 28.3% for fiscal
1996.
 
                                       41
<PAGE>
    INCOME FROM OPERATIONS.  As a result of the above factors, income from
operations rose 402.7%, from $3.7 million in fiscal 1996 to $18.6 million in
fiscal 1997, which constituted 11.6% and 18.1% of sales, respectively, for such
years.
 
    INTEREST EXPENSE.  Interest expense for fiscal 1997 increased by $0.3
million or 300.0%, to $0.4 million from $0.1 million for fiscal 1996. This
increase was attributed to an increase in interest expense on ESP's working
capital loan.
 
    OTHER INCOME (EXPENSE).  Other expense for fiscal 1997 decreased by $0.1
million or 100.0%, to $0.0 from $0.1 million for fiscal 1996. This decrease was
primarily attributable to a $0.1 million decrease in foreign exchange losses
associated with the Mexican peso.
 
    PROVISION FOR INCOME TAXES.  Provision for income taxes for fiscal 1997
increased by $5.7 million or 300.0%, to $7.6 million from $1.9 million for
fiscal 1996, resulting in effective tax rates of 41.8% and 53.6%, respectively.
The increase over the federal statutory rate of 35% and 34% in fiscal 1997 and
1996, respectively, is a result of taxes on ESP's foreign operations and
inclusion of state income taxes. The provision for income taxes for fiscal 1996
also includes an IRS assessment for state taxes.
 
    NET INCOME.  As a result of the above factors, net income rose 523.5%, from
$1.7 million in fiscal 1996 to $10.6 million in fiscal 1997, which constituted
5.1% and 10.3% of sales, respectively, for such years.
 
FISCAL YEAR ENDED DECEMBER 31, 1996 COMPARED TO FISCAL YEAR ENDED DECEMBER 31,
  1995
 
    REVENUES.  Revenues for fiscal 1996 increased by $11.4 million, or 54.8%, to
$32.2 million from $20.8 million for fiscal 1995. $6.3 million of this increase
was attributable to the increase in domestic equipment sales as a result of the
implementation of basic emissions testing programs in Georgia and Texas, and
$3.6 million of the increase in revenue was attributable to the increase in
international sales of equipment as a result of the implementation of an
enhanced emissions testing program in Mexico City, Mexico. The remaining $1.5
million of the increase in revenues was attributable to increased revenues from
domestic service as a result of a large number of new service contracts in
California following the expiration of warranties on the related products.
 
    GROSS PROFIT.  Gross profit for fiscal 1996 increased by $5.0 million, or
63.3%, to $12.9 million from $7.9 million for fiscal 1995. This increase was
primarily attributable to an increase in revenues from domestic sales of
equipment. As a percentage of revenues, gross profit increased to 39.9% for
fiscal 1996 from 37.8% for fiscal 1995. The increase in gross profit as a
percentage of revenues was primarily a result of a higher average selling price
and profit margin for equipment sold to decentralized facilities in connection
with the implementation of basic emissions testing programs in Texas and Georgia
in fiscal 1996, compared to the average selling price and profit margin on
residual sales of equipment in fiscal 1995 when no states implemented either
basic or enhanced emissions testing programs. The increase also was attributable
to high gross profit margins on certain equipment upgrades that were sold in
California during fiscal 1996. Gross profit was reduced by a one-time inventory
reserve adjustment of $0.7 million in connection with the acquisition of ESP by
Wellman plc.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses for fiscal 1996 increased by $2.7 million, or 42.2%, to
$9.1 million from $6.4 million for fiscal 1995. Selling expenses for fiscal 1996
increased by $0.5 million or 41.7% to $1.7 million from $1.2 million for fiscal
1995. This increase was primarily attributable to increased salaries,
commissions and benefits paid to new personnel added in order to promote sales
efforts in Georgia and Texas. Administrative expenses for fiscal 1996 increased
by $1.9 million or 50.0% to $5.7 million from $3.8 million for fiscal 1995. This
increase was primarily attributable to an increase in legal fees, charges and
expenses incurred in connection with the acquisition of ESP by Wellman plc and
an increase in performance bonuses payable to certain members of management.
Engineering expenses for fiscal 1996 increased by $0.3 million or 21.4% to $1.7
million from
 
                                       42
<PAGE>
$1.4 million for fiscal 1995. This increase was primarily attributable to
increased compensation and benefits paid to additional personnel and independent
contractors in connection with the development of, and enhancements to, testing
equipment sold in states that implemented emissions testing programs during
1996. As a percentage of revenues, selling, general and administrative expenses
decreased to 28.3% for fiscal 1996 from 30.8% for fiscal 1995.
 
    INCOME FROM OPERATIONS.  As a result of the above factors, income from
operations rose 146.7%, from $1.5 million in fiscal 1995 to $3.7 million in
fiscal 1996, which constituted 7.0% and 11.6% of sales for such years,
respectively.
 
    INTEREST EXPENSE.  Interest expense for fiscal 1996 decreased by $0.1
million or 50%, to $0.1 million from $0.2 million for fiscal 1995. This decrease
was attributed to a decrease in interest expense associated with ESP's
outstanding debt.
 
    OTHER INCOME (EXPENSE).  Other income (expense) for fiscal 1996 decreased by
$0.3 million or 150.0%, to $(0.1) million from $0.2 million for fiscal 1995.
This decrease was primarily attributable to a $0.3 million increase in foreign
exchange losses.
 
    PROVISION FOR INCOME TAXES.  Provision for income taxes for fiscal 1996
increased by $1.0 million or 111.1%, to $1.9 million from $0.9 million for
fiscal 1995, resulting in effective tax rates of 53.6% and 58.8%, respectively.
The increase over the federal statutory rate of 34% is a result of taxes on
ESP's foreign operations and inclusion of state income taxes. Additionally,
included in fiscal 1996 and 1995 is an IRS assessment for state and federal
taxes, respectively.
 
    NET INCOME.  As a result of the above factors, net income rose 183.3% from
$0.6 million in fiscal 1995 to $1.7 million in fiscal 1996, or 2.9% and 5.1% of
sales, respectively.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Cash provided by (used in) operating activities was $7.7 million, $(8.3)
million, $(7.8) million, $3.7 million and $0.5 million for the nine months ended
September 30, 1998 and 1997 and for the years ended December 31, 1997, 1996 and
1995, respectively. Cash used in operations in fiscal 1997 and for the nine
months ended September 30, 1997 resulted primarily from increases in accounts
receivable and inventories associated with the increase in sales from fiscal
1996, partially offset by an increase in accounts payable.
 
    Cash used in investing activities of $0.2 million, $0.5 million, $0.6
million, $0.1 million and $0.2 million for the nine months ended September 30,
1998 and 1997 and for the years ended December 31, 1997, 1996 and 1995,
respectively, resulted from capital expenditures.
 
    Cash provided by (used in) financing activities was $(3.1) million, $6.3
million, $7.8 million, $(0.4) million and $(0.6) million for the nine months
ended September 30, 1998 and 1997 and for the years ended December 31, 1997,
1996 and 1995, respectively. Cash provided by financing activities in fiscal
1997 and for the nine months ended September 30, 1997 resulted from borrowings
under ESP's revolving credit agreement. Cash used in financing activities during
the nine months ended September 30, 1998 resulted from net repayments and
borrowings under ESP's revolving credit agreements and payment of debt issuance
costs.
 
ENVIROTEST SYSTEMS CORP.
 
    Envirotest is the most experienced operator of centralized vehicle emissions
testing programs in the approximately $250 million North American market, having
tested more than 150 million vehicles since its inception in 1974. Envirotest
operates or is under contract to operate 14 of the 21 vehicle emissions testing
programs in the 16 states that have adopted a centralized testing program and
operates the only such program in Canada. We tested approximately 11.8 million
motor vehicles in 1998, which represented approximately 70% of the total North
American centralized testing market revenues. Envirotest operates
 
                                       43
<PAGE>
these programs under long-term exclusive contracts with state and local
governments. These contracts generally have terms ranging from five to ten
years. Envirotest estimates that as of September 30, 1998, it had a contractual
backlog to provide centralized emissions testing services of approximately $873
million through 2008. Envirotest revenues are predictable and stable due to the
long term nature of its exclusive contracts, which typically have initial terms
of seven to ten years, and predictable testing volumes. Such volumes could,
however, be reduced in future contracts if EPA's draft "clean screening"
guidance is finalized in its current form, potentially reducing the number of
vehicles subject to traditional emission testing and thus reducing Envirotest's
revenues and profits. Envirotest believes that as the incumbent operator in its
existing programs it generally has a competitive advantage when its programs are
rebid, primarily because Envirotest has already incurred the costs of
establishing the program network and has gained valuable experience in operating
the program. Since 1990, all of Envirotest's emissions testing contracts that
provided for renewal or extension have been renewed or extended beyond their
initial terms except one contract with Maryland that was not material.
 
    Envirotest conducts its current operations directly and through its
principal wholly-owned subsidiaries, Envirotest Technologies, Inc., which does
business in Florida and Minnesota, and Envirotest Illinois, Inc., Envirotest
Wisconsin, Inc. and Envirotest Systems Corp. ("ESC--WA"), which do business in
Illinois, Wisconsin and Washington State, respectively. Envirotest's British
Columbia, Canada operations are conducted through a British Columbia
partnership, Envirotest Canada, which is wholly-owned by Envirotest (through its
subsidiaries).
 
    The following table sets forth certain income and expense items from
Envirotest's consolidated statements of operations expressed as a percentage of
revenues for the periods indicated.

FISCAL YEAR ENDED SEPTEMBER 30, 1998 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1997
 
    REVENUES.  Contract revenues increased to $168.7 million in fiscal 1998 from
$140.7 million in fiscal 1997, an increase of $28.0 million or 19.9%. The
increase is primarily attributable to additional revenues of $20.8 million
generated by new or extended emissions programs in Illinois and Connecticut and
other increases of $7.2 million from additional test volumes and contractual fee
increases.
 
                                       44
<PAGE>
    GROSS PROFIT.  Gross profit increased to $63.7 million in fiscal 1998 from
$41.8 million in fiscal 1997, an increase of $21.9 million or 52.4%. As a
percentage of contract revenues, gross profit increased to 37.8% in fiscal 1998
from 29.7% in the corresponding period in fiscal 1997, an absolute increase of
8.1%. This increase was attributable to increased revenues and continued
improvements in operational efficiencies, partially offset by a $2.6 million
write-off of machinery and equipment that will not be utilized due to the
conversion of the Ohio and Connecticut programs to a new emissions test.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to $19.5 million in fiscal 1998 from $19.0
million in fiscal 1997, an increase of $0.5 million or 2.6%. As a percentage of
contract revenues, selling, general and administrative expenses decreased to
11.6% in fiscal 1998 from 13.5% in fiscal 1997, an absolute decrease of 2.1%.
The increase in selling, general and administrative expenses is not specific to
any one event.
 
    AMORTIZATION EXPENSE.  Amortization expense remained constant at $2.4
million for fiscal 1998 and fiscal 1997.
 
    OTHER (GAINS) AND LOSSES.  Non-recurring acquisition costs associated with
Envirotest's sale to ESP on October 16, 1998 totaled $7.8 million for fiscal
1998 and represented attorney, investment banking and other consulting fees that
Envirotest was responsible for paying and was partially offset by the gain on
the Pennsylvania settlement of $2.6 million in fiscal 1998 represents
adjustments to provisions made earlier for claims resulting from the
Pennsylvania contract cancellation that have been settled or resolved and are
unlikely to present future liability. A gain on the Pennsylvania settlement of
$4.0 million was included in fiscal 1997.
 
    INCOME FROM OPERATIONS.  Income from operations increased to $36.6 million
in fiscal 1998 compared to $24.3 million in fiscal 1997. Income from operations
as a percentage of contract revenues increased to 21.7% in fiscal 1998 compared
to 17.3% in fiscal 1997, an absolute increase of 4.4%. The increase is primarily
attributable to increases in revenue and improvements in gross profit margins.
 
    INTEREST EXPENSE.  Interest expense decreased to $33.8 million in fiscal
1998 from $40.2 million in fiscal 1997, a decrease of $6.4 million. This
increase was primarily attributable to the redemption of $50 million of senior
debt in September of 1997 reducing interest expense in fiscal 1998 by $4.6
million. In addition, Envirotest capitalized $1.2 million of interest expense in
fiscal 1998 related to the upgrade of the Illinois program.
 
    INTEREST AND OTHER INCOME.  Interest and other income of $5.1 million in
fiscal 1998 decreased $3.5 million from $8.6 million in fiscal 1997. The
decrease is directly related to the use of cash, cash equivalents and
available-for-sale securities in the redemption of the $50 million of senior
debt and the $29 million repurchase of 4.4 million shares in the "Dutch" auction
tender offer in September 1997.
 
    PROVISION FOR INCOME TAXES.  Fiscal 1998 income tax expense of $0.7 million,
primarily represents the federal alternative minimum tax, after giving effect to
the use of $5.5 million of deferred tax assets. There was no income tax benefit
on the pretax loss of $7.3 million in fiscal 1997, as Envirotest increased a
valuation allowance by $3.6 million to fully reserve the net deferred tax asset.
In fiscal 1998 and 1997, the income tax expense (benefit) was lower than the
combined federal and state effective tax rate of approximately 39%, as a result
of adjusting the valuation allowance to restate the net deferred tax asset to an
amount estimated to be realizable in future years. The estimate on the amount of
deferred tax asset to be realized is reviewed quarterly and the valuation
allowance adjusted accordingly.
 
    EXTRAORDINARY LOSS.  During fiscal 1997, Envirotest recognized a
non-recurring charge, reflected as an extraordinary loss from the write-off of
capitalized debt acquisition costs and transaction costs of $1.3 million, in
connection with the repurchase of $50.0 million aggregate principal amount of
its 9 1/8% Senior Notes due 2001, completed September 17, 1997.
 
                                       45

    NET INCOME.  Net income was $7.2 million in fiscal 1998 compared to a net
loss of $8.6 million in fiscal 1997, an increase of $15.8 million.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1997 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1996
 
    REVENUES.  Revenues in fiscal 1997 increased by $16.2 million, or 13.0%, to
$140.7 million from $124.5 million in fiscal 1996. The increase is primarily
attributable to additional revenues of $13.5 million generated by new or
extended emissions programs in Indiana, Illinois and Ohio and a full year of
operations in the Washington State program, acquired on January 30, 1996;
additional revenues from the British Columbia program of $2.1 million,
operations of which were impacted by the employee strike during fiscal 1996; and
other increases of $3.2 million from additional test volumes and contractual fee
increases. These increases were partly offset by the loss in revenue of $2.4
million from the expiration of the California Quality Assurance contract in
September 1996.
 
    GROSS PROFIT.  Gross profit increased to $41.8 million in fiscal 1997 from
$22.3 million in fiscal 1996, an increase of $19.5 million or 87.3%. As a
percentage of contract revenues, gross profit increased to 29.7% in fiscal 1997
from 17.9% in the corresponding period in fiscal 1996, an absolute increase of
11.8%. This increase was attributable to several factors including contributions
of $9.0 million from new or extended contracts in Indiana, Illinois and Ohio;
$2.6 million in the British Columbia program, which benefited from an additional
volume increase and settlement of an employee strike that hampered results in
fiscal 1996; $4.1 million from improvements in operational efficiencies and test
volume increases in most other programs; and $3.3 million from the reduction in
the deferred charge amortization.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses decreased to $19.0 million in fiscal 1997 from $21.8
million in fiscal 1996, a decrease of $2.8 million or 12.6%. As a percentage of
contract revenues, selling, general and administrative expenses decreased to
13.5% in fiscal 1997 from 17.5% in fiscal 1996, an absolute decrease of 4.0%.
The decrease in selling, general and administrative expenses is primarily due to
absence of relocation costs of $1.5 million recorded in fiscal 1996 resulting
from the consolidation of the corporate headquarters to Sunnyvale, California,
and lower engineering support costs as new programs matured.
 
    AMORTIZATION EXPENSE.  Amortization expense decreased to $2.4 million in
fiscal 1997, a decrease of $1.0 million from $3.4 million in fiscal 1996. The
decrease was attributable to the expiration of the California Quality Assurance
contract as of September 30, 1996.
 
    OTHER (GAINS) AND LOSSES.  A corporate relocation expense of $1.9 million
for fiscal 1996 represents the costs associated with closing the Phoenix
corporate headquarters and other restructuring costs. Gain on the Pennsylvania
settlement of $3.9 million in fiscal 1997 represents adjustments to provisions
made earlier for claims resulting from the Pennsylvania contract cancellation
that have been settled or resolved and are unlikely to present future liability.
A gain on the Pennsylvania settlement of $15.3 million was included in fiscal
1996.
 
    INCOME FROM OPERATIONS.  Income from operations increased to $24.3 million
in fiscal 1997 compared to $10.6 million in fiscal 1996. Income from operations
as a percentage of contract revenues increased to 17.3% in fiscal 1997 compared
to 8.5% in fiscal 1996, an absolute increase of 8.8%. The increase is primarily
attributable to increases in revenue, improvements in gross profit margins,
reductions in selling, general and administrative expenses and amortization
expenses, and the absence of non-recurring relocation expenses, partially offset
by the gain recorded on the Pennsylvania settlement in fiscal 1996.
 
    INTEREST EXPENSE.  Interest expense increased to $40.2 million in fiscal
1997 from $38.9 million in fiscal 1996, an increase of $1.3 million. These
increases were primarily attributable to a full year of interest expense on debt
associated with the Wisconsin, Washington and Indiana programs.
 
                                       46
<PAGE>
    INTEREST AND OTHER INCOME.  Interest and other income of $8.6 million in
fiscal 1997 represented a decrease of $0.3 million from $8.9 million in fiscal
1996.
 
    PROVISION FOR INCOME TAXES.  There was no income tax benefit on the pretax
loss of $7.3 million in fiscal 1997, as Envirotest increased a valuation
allowance by $3.6 million to fully reserve the net deferred tax asset. In fiscal
1996, income tax expense was $5.6 million on pre-tax loss of $19.4 million. In
both fiscal 1997 and 1996, the income tax benefit was lower than the combined
federal and state effective tax rate of approximately 39%, as a result of
increasing the valuation allowance to reduce the net deferred tax asset to an
amount estimated to be realizable in future years. The estimate on the amount of
net deferred tax asset to be realized is reviewed quarterly and the valuation
allowance adjusted accordingly.
 
    EXTRAORDINARY LOSS.  During fiscal 1997, Envirotest recognized a
non-recurring charge, reflected as an extraordinary loss from the write-off of
capitalized debt acquisition costs and transaction costs of $1.3 million, in
connection with the repurchase of $50.0 million aggregate principal amount of
the Envirotest Senior Notes, which was completed on September 17, 1997.
 
    NET LOSS.  The net loss was $8.6 million in fiscal 1997 compared to $25.1
million in fiscal 1996, a decrease of $16.5 million.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Cash and cash equivalents, available-for-sale securities, and restricted
cash increased to $90.4 million at September 30, 1998 from $79.2 million at
September 30, 1997. The increase of $11.2 million was primarily a result of cash
generated from operations of $64.0 million and proceeds from the sale of excess
properties of $21.8 million, offset by the purchase of property, plant and
equipment for $55.9 million; and debt and capital lease payments of $18.4
million.
 
    Envirotest's primary uses of cash include funding capital expenditure
requirements, payments on capital and operating leases, principal and interest
payments, and other working capital needs. Envirotest's capital and operating
leases currently require minimum lease payments of approximately $14.9 million
in 1998, decreasing to approximately $10.3 million in 2003 and further
decreasing thereafter as certain leases are scheduled to expire.
 
    Envirotest's capital expenditures include maintenance capital expenditures
for existing facilities and development and construction expenditures for new
emissions facilities. Envirotest's development and construction capital
expenditures are dependent on the number of contracts we are awarded and are
only incurred after the contract has been signed. After signing a contract,
Envirotest may incur significant development and construction expenditures,
which Envirotest expects to finance with existing cash resources, internally
generated funds, additional borrowings and alternative financing sources,
including leasing alternatives. It generally takes one to two years after a
contract has been signed for a program to begin operations and generate
revenues, depending on the size of the program.
 
    Envirotest's principal commitments at September 30, 1998 consist of capital
expenditures for the implementation of the Illinois program, estimated at $1.2
million net of the $7.1 million payments from the state. In fiscal 1999,
Envirotest also intends to spend approximately $10.2 million on implementation
of the Kentucky program, enhancement and other maintenance capital expenditures.
Subsequent to September 30, 1998, the Company agreed to pay $1.5 million to
settle the Ganzcorp claim.
 
    Envirotest believes that its existing cash, cash generated from operations
and alternative financing sources, including leasing alternatives, will be
sufficient to complete implementation of the Illinois program and to meet its
liquidity requirements for the foreseeable future.
 
    Accrued expenses and other current liabilities increased to $45.4 million at
September 30, 1998 from $23.6 million at September 30, 1997. The increase is
primarily attributable to $18.9 million received from the State of Illinois in
conjunction with the implementation of the new testing procedure.

LIQUIDITY AND CAPITAL RESOURCES OF THE COMPANY FOLLOWING THE ACQUISITION OF
  ENVIROTEST AND RELATED TRANSACTIONS
 
    Following the acquisition of Envirotest and the related transactions, our
debt capitalization consists of (i) $100 million aggregate principal amount of
Notes and (ii) a committed $435 million senior secured credit facility of which
$36.1 million will be available for liquidity requirements. As of December 15,
1998, availability under the senior secured credit facility was reduced by $8.9
million in outstanding letters of credit and by $13.0 million due to revolving
borrowings. The borrowings under the senior secured credit facility and the
Notes increase debt service costs. The Notes accrue interest at 13% per annum
and will be payable semi-annually commencing April 30, 1999. The Notes will
mature on October 31, 2008. The senior secured credit facility and the indenture
governing these Notes limit our ability to incur additional debt, to pay
dividends, to redeem capital stock and to sell certain assets. We may incur
additional indebtedness as long as our consolidated cash flow coverage ratio, as
defined in the indenture governing these Notes, is greater than certain minimum
levels or if such additional indebtedness fits within certain exceptions. The
Senior Secured Credit Facility bears interest at various interest rates ranging
from LIBOR plus 2.25% to LIBOR plus 4.00% depending on the Company's financial
ratios. (The Senior Secured Credit Facility also permits the Company to choose
an interest rate based on the prime lending rate of Credit Suisse First Boston
plus a margin or the federal funds rate plus a margin). Through March 31, 1999,
Term Loan A of the Senior Secured Credit Facility bears interest at LIBOR plus
3.25% and Term Loan B bears interest at LIBOR plus 4.00%.
 
    Management believes that based on current financial performance and
anticipated growth, cash flow from operations, together with the available
sources of funds including borrowings under the senior secured credit facility,
will be adequate to make required payments of interest on our indebtedness, to
fund anticipated capital expenditures and working capital requirements and to
enable us to comply with the terms of our debt agreements. Actual capital
requirements may change, particularly as a result of acquisitions we may make,
although no acquisitions are currently contemplated. We expect that capital
expenditures (exclusive of acquisitions) will be approximately $5 to $15 million
annually from 1999 to 2003. We believe that these capital expenditures will be
sufficient to maintain high quality equipment and services. Our future
performance and ability to service or refinance the Notes and to extend or
refinance the senior secured credit facility will be subject to future economic
conditions and to financial, business and other factors, many of which are
beyond our control.
 
    In connection with the acquisition of Envirotest, our sole stockholder,
EnviroSystems Corp., issued 15% senior discount notes due 2009 with a principal
amount at maturity of $207 million. Interest on these senior discount notes will
accrue from October 16, 1998 and be payable semiannually on April 30 and October
31 of each year, but will not be payable in cash prior to April 30, 2004. Since
EnviroSystems Corp. has no material business operations, sources of income or
assets of its own, other than its shares of the Company, it is dependent upon
the profitability and cash flows of the Company and the payment of funds by the
Company to it in the form of loans, dividends, fees and otherwise, as well as
its own credit arrangements.
 
INFLATION
 
    Inflation was not a material factor in either the sales or the operating
expenses of the Company during the periods presented herein.
 
YEAR 2000 ISSUE
 
    The Company has a Year 2000 project designed to identify and assess the
risks associated with its information systems, products, operations and
infrastructure, suppliers, and customers that are not Year 2000 compliant, and
to develop, implement, and test remediation and contingency plans to mitigate
these
 
                                       48
<PAGE>
risks. The project comprises four phases: (1) identification of risks, (2)
assessment of risks, (3) development of remediation and contingency plans, and
(4) implementation and testing.
 
    The Company's Year 2000 project is currently in the assessment phase and
with respect to certain information systems in the remediation phase. The
Company believes that its greatest potential risks are associated with its
information systems and systems embedded in its operations and infrastructure.
The Company is at the beginning stage of assessments for its operations and
infrastructure, and cannot predict whether significant problems will be
identified. The Company has not yet determined the extent of contingency
planning that may be required. Based on the status of the assessments made and
remediation plans developed to date, the Company is not in a position to state
the total cost of remediation of all Year 2000 issues. Though the Company does
not expect the total costs to be material, it expects to be able to fund the
total costs through operating cash flows. However, the Company has not yet
completed its assessments, developed remediation plans, or developed any
contingency plans.
 
    As the Year 2000 project continues, the Company may discover additional Year
2000 problems, may not be able to develop, implement or test remediation or
contingency plans, or may find that the costs of these activities exceed current
expectations and become material. In many cases, the Company is relying on
assurances from suppliers that new and upgraded information systems and other
products will be Year 2000 compliant. The Company plans to test such third-party
products, but cannot be sure that its tests will be adequate or that, if
problems are identified, they will be addressed in a timely and satisfactory
way.
 
    Because the Company uses a variety of information systems and has additional
systems embedded in its operations and infrastructure, the Company cannot be
sure that all of its systems will work together in a Year 2000 compliant
fashion. Furthermore, the Company cannot be sure that it will not suffer
business interruptions, either because of its own Year 2000 problems or those of
its customers or suppliers whose Year 2000 problems may make it difficult or
impossible for them to fulfill their commitments to the Company. If the Company
fails to satisfactorily resolve Year 2000 issues related to its products in a
timely manner, it could be exposed to liability to third parties.
 
    The Company is continuing to evaluate Year 2000 related risks and corrective
actions. Risks associated with the Year 2000 problem are pervasive and complex,
can be difficult to identify and to address, and can result in material adverse
consequences to the Company. Even if the Company, in a timely manner, completes
all of its assessments, identifies and tests remediation plans believed to be
adequate, and develops contingency plans believed to be adequate, some problems
may not be identified or corrected in time to prevent material adverse
consequences to the Company.
 
RECENT DEVELOPMENTS
 
    We recently acquired all of the outstanding capital stock of Transervice
Limited, a subsidiary of Wellman (Holdings) Limited for a purchase price of
$18.0 million ($9.25 million in cash, $4.25 in the form of a note periodically
due over the next six months and $4.5 million in the form of a note due in three
years). Transervice provides installation and warranty and other services in
respect of automobile lift and brake equipment manufactured by Wellman Bradbury
plc and warranty support services in respect of diagnostic and emissions testing
equipment manufactured by Crypton plc. In 1997, Transervice had revenues and
operating profits of approximately L7.2 million and L1.0 million, respectively.
 
    The Company has entered into an agreement with Bank of America and BA Credit
Corporation, pursuant to which a Delaware limited liability company, ESP
Financial Services LLC, has been established to provide financing for vehicle
emissions testing equipment to be sold by ESP to decentralized facilities. ESP
Financial Services LLC is 90% owned by ESP and 10% owned by BA Credit
Corporation. After ESP has arranged a sale of vehicle emissions testing
equipment with a decentralized facility owner or operator, ESP Financial will
purchase the equipment from ESP and lease it to the facility. ESP will receive
payment in full for the sale from ESP Financial at the time of sale. ESP
Financial will securitize the lease payments from the decentralized facilities
and after repayment to BA Credit Corporation and its affiliates of the
 
                                       49
<PAGE>
purchase price for the equipment, ESP and BA Credit Corporation will share in
the spread between the actual or implied interest rates on the lease payments
and on the instruments issued in connection with the securitization based on
their respective interests in ESP Financial. It is expected that ESP will at any
time provide up to a maximum of approximately $3,000,000 of equity capital to
ESP Financial, which may be partially or completely lost in the event that one
or more decentralized facilities defaults on their lease payments.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" (SFAS 130). SFAS 130 applies to all
companies and is effective for fiscal years beginning after December 15, 1997.
SFAS 130 establishes standards for the reporting and display of comprehensive
income in a set of financial statements. Comprehensive income is defined as the
change in net assets of a business enterprise during a period from transactions
generated from non-owner sources. It includes all changes in equity during a
period except those resulting from investment by owners and distributions to
owners. The Company has adopted SFAS 130 beginning January 1, 1998.
 
    In June 1997, the Financial Accounting Standards Board issued Statement No.
131 "Disclosures about Segments of an Enterprise and Related Information" (SFAS
131). SFAS 131 applies to all public companies and is effective for fiscal years
beginning after December 15, 1997. SFAS 131 requires that business segment
financial information be reported in the financial statements utilizing the
management approach. The management approach is defined as the manner in which
management organizes the segments within the enterprise for making operating
decisions and assessing performance. The Company has adopted SFAS 131 beginning
January 1, 1998. The Company's operations prior to the acquisition of Envirotest
are managed all within one segment. The Company is presently reviewing its
reporting as required by SFAS 131.
 
    In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (FAS
133). The new standard requires companies to record derivatives on the balance
sheet as assets or liabilities, measured at fair value. Gains or losses
resulting from changes in the values of those derivatives should be reported in
the statement of operations or as a deferred item, depending on the use of the
derivatives and whether they qualify for hedge accounting. The key criterion for
hedge accounting is that the derivative must be highly effective in achieving
offsetting changes in fair value or cash flows of the hedged items during the
term of the hedge. No material impact is expected with the adoption of FAS 133.
 
    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up Activities." SOP
98-5 provides guidance on the financial reporting of start-up costs and
organization costs, which should be expensed as incurred. This SOP is effective
for the Company's 2000 fiscal year. The Company has reviewed the provisions of
this SOP and does not believe that adoption of this standard will have a
material effect upon its results of operations, financial position, or cash
flows.
 
    In March 1998, the Accounting Standards Executive Committee issued SOP 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use." SOP 98-1 provides guidance on when costs related to software
developed or obtained for internal use should be capitalized or expensed. This
SOP is effective for the Company's 1999 fiscal year. The Company has reviewed
the provisions of the SOP and does not believe adoption of this standard will
have a material effect upon its results of operations, financial position, or
cash flows.

                        INDUSTRY AND REGULATORY OVERVIEW
 
    Public awareness of air pollution and its hazardous effects on human health
and the environment has increased in recent years. The EPA estimates that in the
United States alone approximately 46 million persons live in areas where air
quality levels have failed to meet the EPA's national air quality standards.
Increased awareness of air pollution and its hazardous effects on human health
and the environment has led many governmental authorities to pass more stringent
pollution control measures. One especially effective measure which many
governmental authorities have adopted is vehicle emissions testing. Vehicle
emissions produce approximately 50% of the ozone air pollution and nearly all of
the carbon monoxide air pollution in metropolitan areas. The EPA estimates that
enhanced emissions testing on motor vehicles is approximately 10 times more
cost-effective in reducing air pollution than increasing controls on stationary
pollution sources such as factories and utilities. Consequently, the EPA has
made emissions testing an integral part of its overall effort to reduce air
pollution by ensuring that vehicles meet emissions standards throughout their
lives.
 
    We estimate that the world market potential for vehicle emissions testing
services is currently in excess of 670 million vehicles. There are approximately
240 million vehicles, or 36% of the world total, in the U.S. and Canada. Over 90
million of these U.S. and Canadian vehicles are currently subject to annual or
biennial emissions testing and approximately 65 million paid tests and re-tests
are conducted annually in these markets. In general, these tests are performed
either in a centralized program or in a decentralized program. In a centralized
program, vehicle owners take their vehicles to one of a small number of special
centralized facilities to be tested. These facilities only perform tests; they
do not repair vehicles. Usually, a private contractor licensed by the government
operates the centralized facility. In a decentralized program, vehicle owners
take their vehicles to a service station, automotive repair shop or dealership
to be tested. These decentralized facilities both perform tests and repair
vehicles. The EPA has granted state and local governmental authorities the
discretion to determine how best to establish and operate a network of emissions
testing facilities, including the flexibility to choose either a centralized or
a decentralized program. In 1997, centralized programs in the U.S. and Canada
performed approximately 23.0 million paid tests (36% of the total tests) and
generated approximately $250 million in revenues, while facilities in
decentralized markets in the United States performed approximately 41.7 million
tests (64% of the total tests) and generated approximately $816 million in
revenues. The percentage of programs which are either centralized or
decentralized has remained relatively constant since 1991. We estimate that the
North American market for decentralized vehicle emissions testing equipment will
total approximately $1.0 billion through 2001 and that thereafter the North
American market will decline significantly, with future demand for these
products dependent on the growth of demand in international markets.
 
    Vehicle emissions control requirements have become progressively more
stringent since the passage of the Clean Air Act in 1970. The 1990 Amendments,
in particular, emphasized the need for effective emissions control programs and
in 1992 the EPA adopted regulations that required 181 geographic areas to
implement certain types of emissions control programs by certain dates,
depending on the area's population and its level of air pollution. The EPA has
the authority under the Clean Air Act to withhold non-safety related federal
highway funds from states that fail to implement such mandated programs by
prescribed deadlines. To date, the EPA has been willing, in certain
circumstances, to grant extensions of these deadlines and it has yet to impose
any sanctions or penalties for non-compliance.
 
    The EPA recently announced certain proposals that may impact emissions
testing programs. On May 7, 1998, the EPA issued a proposal on the potential use
of so-called "clean screening" methods in emissions testing programs. Under the
proposal, individual states would be able to modify existing or planned
emissions testing programs to reduce or eliminate vehicle emissions testing for
certain categories of low emission vehicles. If the EPA adopts guidelines
substantially along the lines of its May 7, 1998 proposal, the number of
vehicles subject to traditional emissions testing would decrease. We believe
that such a decrease would not significantly affect our revenues because our
current contracts with states that
 
                                       51
<PAGE>
operate centralized programs guarantee specified numbers of tests, and in states
that operate decentralized programs we do not earn revenue from performing tests
but from selling testing equipment to private sector facilities. The clean
screening proposal would also permit states to consider the use of roadside
remote sensing devices to excuse certain categories of vehicles from regularly
scheduled testing. We believe it is premature to consider what effect, if any,
remote sensing might have on our business because such devices have not been
developed to the point where they are sufficiently accurate to be used as a
substitute for current emissions tests, and because we ourselves are engaged in
research and development of remote sensing devices and would expect to pursue
growth opportunities in this area. More recently, on July 31, 1998, the EPA
issued a final study which concluded that more stringent air quality standards
for motor vehicle emissions are needed, technologically feasible, and
cost-effective. We believe that the setting of such standards will be the most
important EPA regulatory initiative affecting motor vehicles since the passage
of the 1990 Amendments. We believe that the EPA study is likely to result in
more stringent standards that will have the effect of increasing the number of
areas which must implement emissions testing programs and therefore potentially
increase the market for our products and services.
 
    Since 1977, when Federal legislation first required states to comply with
emissions standards through the use of testing programs, California has been a
leader in testing procedures and technical standards. California has
approximately 22 million vehicles subject to emissions testing, more than three
times that of any other state. California's testing program is overseen by the
California Bureau of Automotive Repair ("BAR"). The California BAR has revised
its emissions testing standards three times: in 1984, 1990 and, most recently,
in 1997. With each of these revisions, the California BAR has required the use
of new, more sophisticated and more accurate emissions testing and analysis
equipment, which must be certified by the California BAR. California's testing
standards have become the benchmark for emissions testing both in the United
States and in many foreign countries. All states with decentralized programs and
many states with centralized programs require emissions testing and analysis
equipment used in their programs to be either "BAR-84," "BAR-90," or "BAR-97"
certified, with all newly-implemented enhanced programs requiring BAR-97
certification.
 
    As emissions testing equipment has become more technologically advanced,
government regulators have required that testing facilities use this more
advanced equipment. The most significant technological advance that has occurred
in the emissions testing industry over the past decade is the development of
"enhanced" testing systems. Prior to 1990, the EPA required government agencies
to test vehicles only for emissions of carbon monoxide and hydrocarbons (which
form ground-level ozone or "smog"). During this "basic" test, a technician
inserts a probe in the vehicle's tailpipe while the vehicle is idling and
emissions analyzers then measure pollution levels in the exhaust. These basic
tests worked well for pre-1981, non-computerized vehicles containing carburetors
because typical emission control problems involved incorrect air/fuel mixtures
and such problems increase pollution levels in the exhaust even when the vehicle
is idling. However, today's vehicles have different emissions problems. For
tests on modern vehicles to be effective, the equipment must measure nitrogen
oxide emissions (which also cause smog) and must test the vehicle under
simulated driving conditions. The EPA now requires these "enhanced" tests in
some areas. A technician conducts these enhanced tests on a dynamometer, a
treadmill-type device that simulates actual driving conditions, including
periods of acceleration, deceleration and cruising.
 
    A number of recent international initiatives evidence the increasing
recognition by foreign countries of the hazardous effects of air pollution to
human health and the environment. We believe that foreign countries will
continue to follow the lead of the United States in pollution control and, more
particularly, vehicle emissions testing, and will adopt or upgrade existing
emissions testing programs as an efficient and effective step towards reducing
air pollution. A number of foreign countries have implemented various forms of
mandatory testing programs, including the United Kingdom, Germany, Canada
(certain provinces), Mexico and Japan, and a number of others are considering
developing or expanding mandatory or voluntary testing programs, including
Poland, the Philippines, Brazil, Argentina, and Chile.

                                    BUSINESS
 
OVERVIEW
 
GENERAL
 
    We are the leading worldwide provider of vehicle emissions testing equipment
and services. We manufacture equipment that tests vehicle emissions for
compliance with air pollution standards and operate testing programs on behalf
of states and other jurisdictions. We estimate that we have an approximate 35%
share of the domestic market for vehicle emissions testing equipment used by
independent service stations and other service providers in states that have
adopted a "decentralized" program (representing an approximate 30% share of the
domestic market for basic testing equipment and an approximate 48% share of the
domestic market for higher-margin enhanced testing equipment). We also operate,
or are under contract to operate, 14 of the 21 testing programs in the 16 states
that have adopted a centralized program and we operate the only such program in
Canada. Envirotest tested approximately 11.8 million motor vehicles in fiscal
1998 which represented approximately 70% of the total North American centralized
testing market revenues. As of September 30, 1998, we had a contractual backlog
to provide centralized emissions testing services of approximately $873 million
through 2008.
 
HISTORY
 
    Both ESP and Envirotest originated from United Technologies Corporation, an
innovator in emissions testing technology. ESP was formed in 1989 in connection
with a management buyout of the decentralized testing division of United
Technologies Corporation. In April 1996, Wellman plc, a then-publicly
incorporated United Kingdom company, bought ESP. Alchemy recently bought Wellman
plc and thus became the indirect parent of ESP and its subsidiaries. Envirotest
has operated in the vehicle emissions testing business since 1974 through its
predecessor company, Hamilton Testing Systems, which was acquired in a
management buyout from United Technologies Corporation in 1990. Hamilton Testing
Systems commenced operations in the emissions testing business in 1974 with the
award of the contract for the Arizona testing program, the first centralized,
test-only program in the United States. Subsequently, Envirotest acquired
Envirotest Technologies, Inc., from Electronic Data Systems, adding an
additional five testing programs shortly before adoption of the rules and
regulations by the EPA implementing the 1990 amendments to the Clean Air Act. In
1996, Envirotest acquired two additional testing programs from Systems Control,
Inc. and hired the senior management team of Systems Control. Envirotest became
a publicly owned company in 1993.
 
THE ACQUISITION OF ENVIROTEST AND RELATED TRANSACTIONS
 
    The combination of ESP and Envirotest has created an emissions testing
industry leader. In the combination, ESP acquired all of the outstanding capital
stock of Envirotest through a tender offer and related merger transaction for
approximately $266.3 million. In connection with the acquisition, we made a
private offering of these Notes and redeemed or repaid certain indebtedness of
Envirotest, ESP and their subsidiaries.
 
    After these transactions and a reorganization of our affiliated companies,
we became a direct wholly-owned subsidiary of EnviroSystems Corp. and ESP and
Envirotest became our direct, wholly-owned subsidiaries.
 
    We believe our new position as the overall industry leader will allow us to
solidify our domestic position and expand internationally by offering a broad
range of vehicle emissions testing equipment and services. We also believe that
Envirotest's relatively consistent revenues will complement the revenues of ESP,
which historically have fluctuated significantly as states have periodically
implemented decentralized testing programs or modified existing programs. In
addition, the combination of ESP and Envirotest will
 
                                       53
<PAGE>
allow us to eliminate duplicative management, staff and facilities. We estimate
this will save $9.4 million, of which $4.2 million has been realized to date.
 
BUSINESS STRENGTHS
 
    We believe that we have the following competitive advantages:
 
    INDUSTRY LEADER.  We enjoy leading market positions in both our emissions
testing equipment business and our emissions testing services business. We have
an estimated 35% share of the domestic market for emissions testing equipment
systems used in decentralized programs. We also currently operate, or are under
contract to operate, 14 of the 21 programs in the 16 states that have adopted
centralized programs and the only such program in Canada. In 1998, we performed
over three times the number of tests as our closest competitor in the United
States and Canada and received approximately 70% of the total revenues in the
centralized testing market for such period.
 
    STABLE REVENUE SOURCE.  Our centralized vehicle emissions testing services
business provides a stable source of revenues. We generally provide services to
states, municipalities and other jurisdictions under long-term contracts of
between five and ten years that include agreed upon per test fees that we earn
over the life of the contracts. The demand for our testing services in these
jurisdictions presently is generally fixed because the tests are mandated by
current law. The actual number of tests may fluctuate. For the twelve months
ended September 30, 1998, our centralized vehicle emissions testing business
generated revenues of $168.7 million and EBITDA of $66.9 million. We estimate
that as of September 30, 1998, we had a contractual backlog to provide
centralized emissions testing services of approximately $873 million through
2008.
 
    TECHNOLOGICAL LEADERSHIP AND SUPERIOR CUSTOMER SERVICE.  We believe that we
are the technological leader in the design and manufacture of vehicle emissions
testing equipment. Our intellectual property includes proprietary software
programs and more than 70 patents on emissions testing and related products. Our
testing systems are among the most user-friendly, efficient products available.
This efficiency allows testing facilities to maximize the number of tests they
can perform in a set period of time and therefore their revenues. In addition,
our staff of approximately 182 company-trained direct service technicians who
operate from a network of 10 service hubs throughout the United States provides
the best customer service in the industry.
 
    EXPERIENCED MANAGEMENT TEAM.  Our management team is one of the most
experienced in the vehicle emissions testing industry. Our management team,
which is comprised of certain of the senior members of the former managements of
ESP and Envirotest, has a combined 40 years of experience in the industry and
has demonstrated its ability to succeed in both the emissions testing equipment
business and the emissions testing services business. We believe that the
combination of ESP and Envirotest creates the leading management team in the
vehicle emissions testing industry.
 
BUSINESS STRATEGY
 
    Our objective is to maximize our long term profitability by enhancing our
leading positions in the vehicle emissions testing equipment and testing
services businesses through the following strategies:
 
    EXPAND DOMESTIC BUSINESS.  We intend to (i) expand our share of the market
for emissions testing equipment, particularly higher margin enhanced systems, in
states and other jurisdictions that have adopted decentralized testing programs,
(ii) capture as large a share as possible of new business if additional states
and municipalities implement laws and regulations that require use of these
products, (iii) extend or renew our existing contracts with states,
municipalities and other jurisdictions to which we provide centralized testing
services and (iv) bid successfully for any new mandates to provide these
services.
 
                                       54
<PAGE>
    REALIZE BENEFITS FROM ACQUISITION OF ENVIROTEST.  We will integrate the
equipment and testing businesses to take advantage of synergies and economies of
scales in, among other things, research and development, marketing and
government relations. We believe that the combination of the two businesses will
help us penetrate the developing international market for vehicle emissions
testing because our breadth of experience and expertise will allow us to offer a
broad range of vehicle emissions products and services. As a result of the
combination of the two businesses, we also expect to save approximately $9.4
million as a result of the elimination of duplicative management, staff and
facilities. Finally, we believe that Envirotest's relatively consistent revenues
will complement the revenues of ESP, which historically have fluctuated
significantly as states have periodically implemented decentralized testing
programs or modified existing programs.
 
    EXTEND TECHNOLOGICAL LEADERSHIP.  By integrating the research and
development groups of ESP and Envirotest, we will be able to extend our
technological leadership. We intend to improve our emissions testing equipment
and expand our product offerings to provide the most accurate, reliable and
user-friendly emissions testing equipment available. In addition, we intend to
update our computer software to maximize the rate at which we can test vehicles
in our centralized testing operations. We also plan to continue to work with
leading government policy makers, including particularly the California BAR, in
developing state-of-the-art testing technologies.
 
    EXPAND INTERNATIONAL PRESENCE.  We intend to expand internationally by
offering a broad range of vehicle emissions testing equipment and services to
countries and other jurisdictions around the world that are likely to adopt
emissions testing programs similar to those adopted in the United States. We
plan to offer our advisory services to these countries at the early stages of
their program development, thereby positioning ourselves to become the provider
of choice for both centralized and decentralized testing programs. We intend to
expand our international marketing efforts and offices in the future and expect
to enter into strategic relationships with partners in selected locales.
 
EMISSIONS TESTING EQUIPMENT BUSINESS
 
OVERVIEW
 
    Through ESP, we are the leading worldwide provider of vehicle emissions
testing and analysis equipment to the decentralized market. ESP designs,
manufactures, markets and services equipment that tests motor vehicle emissions
for compliance with air pollution standards imposed by various Federal, state,
and international regulations. Since 1990, ESP has sold over 10,000 testing
systems (including 5,683 systems in the twelve months ended June 30, 1998) in 11
states and 4 foreign countries. ESP sells its emissions testing equipment
primarily to private sector facilities such as service stations, automotive
repair shops, and dealerships that perform emissions testing in states which
have adopted a decentralized program. ESP, by focusing almost exclusively on
designing and developing emissions testing products for the decentralized
market, has developed significant expertise in producing emissions testing
equipment that meets the needs of the owners of emissions testing facilities.
Specifically, ESP has used its extensive technological capabilities to provide
its customers with technologically advanced, easy to use and more efficient
equipment with superior service for that equipment.
 
    ESP's business has been characterized by long lead times for sales and
generally cyclical sales. This is primarily because the states and
municipalities in the United States that have implemented a decentralized
program have generally adopted a target date for implementation which they have
publicly announced 12 to 24 months in advance. This causes surges in demand for
emissions testing equipment from facility owners in a state generally four to
six months prior to the scheduled implementation date. The level of demand is
predictable to a certain extent based on the state's vehicle population.
Following implementation of a state's testing program, ESP continues to earn
revenues in that state from residual sales and, after a one-year warranty
period, from equipment servicing. This pattern of implementation permits ESP to
channel its engineering resources to develop equipment modifications required to
comply with a particular
 
                                       55
<PAGE>
state's testing program and allows ESP to allocate and relocate marketing
personnel to that state prior to its scheduled implementation date in order to
capitalize on the expected customer demand.
 
    In addition, ESP has also experienced surges in demand when states with
existing testing programs have introduced more stringent regulations requiring
the use of enhanced testing systems. Technological advances in the emissions
testing industry have led to the development of enhanced testing systems which
have higher average sales prices and gross margins. While basic testing systems,
which test an automobile's emissions only while the vehicle is in neutral, sell
for approximately $12,000, enhanced testing systems, which test an automobile's
emissions under simulated driving conditions, sell for approximately $35,000 to
$40,000. There are five states which currently require the use of the enhanced
testing systems, and Massachusetts and New Jersey have publicly indicated their
intention to require such systems in the future. The Company believes that more
and more states are likely to require the use of these systems, which ESP
expects will result in continued revenues to ESP at least through 2001. By 2001
substantially all of the states with large vehicle populations will have
completed implementation of their programs. As a result, ESP believes that its
revenues and profits generated by domestic sales of its testing systems will
decline significantly. ESP believes, however, that domestic demand for testing
systems will continue at a reduced level even after implementation of mandated
testing programs is completed for the following reasons: (i) states and
municipalities will adopt more stringent pollution control standards which may
require more technologically advanced testing systems, (ii) advances in
technology will produce emissions testing equipment that is superior to the
technology that is currently available, and (iii) facility owners will need to
replace testing systems after the end of their useful lives.
 
PRODUCTS
 
    ESP currently designs, manufactures and sells three testing systems under
the tradename SystemOne:
 
    - an idle testing system that complies with basic testing requirements;
 
    - a loaded mode testing system that complies with enhanced testing
      requirements; and
 
    - a transient loaded mode testing system that complies with enhanced testing
      requirements.
 
    In an idle test, a technician inserts a probe which measures exhaust
emissions into the vehicle's tailpipe while the vehicle is idling. A loaded mode
emissions test involves the use of an instrument known as a dynamometer that
measures the vehicle's exhaust emissions under simulated driving conditions. A
transient loaded mode test also uses a dynamometer and in addition uses a system
which captures the entire exhaust stream during a test and measures the total
mass of emissions from a vehicle in grams of pollutant per mile driven.
 
    An emissions testing system is comprised of an outer-frame cabinet, a
personal computer (including a keyboard, modem, monitor and printers) and
internal and external sampling devices for measuring and analyzing emissions.
The computer systems are pre-loaded with ESP's proprietary emissions testing
software. The testing systems have a modular design, which means that each
component is installed separately. This allows for the addition of optional
testing equipment and for upgrades and modifications. The emissions testing
systems also contain certain anti-tampering devices designed to assure the
integrity of emissions testing results. The central processing unit of the
personal computers contained in all testing systems is secured in a locked
compartment accessible only by ESP and its authorized service technicians. If
someone tampers with the lock on the compartment, the testing system
automatically shuts down and can only be turned on by typing in a computer
access code. This code changes daily and only ESP's authorized service
technicians can access it.
 
    ESP's testing systems are designed to be more mobile than the systems sold
by its competitors. This mobility permits the test operators to move the
equipment to accommodate a variety of vehicles, and allows facility owners to
use the systems in decentralized facilities that have limited available space
for emissions testing. Certain components used in the emissions testing systems
also allow the test operators to
 
                                       56
<PAGE>
perform required emissions tests with less need for direct contact with specific
engine components. These "non intrusive" devices reduce the time to perform
certain tests and the risk of injury to the test operator.
 
    Vehicle emissions testing equipment must be certified for use in each state
prior to sale. All of ESP's testing systems are either BAR-84, BAR-90 or BAR-97
compliant and ESP's emissions testing and analysis equipment is currently
certified in 13 of the 16 states which have adopted decentralized programs and 4
foreign countries. ESP has elected not to apply for certification in Alaska, New
Mexico and Rhode Island because of the relatively small number of vehicles
subject to emissions testing in those states.
 
    Due to the customized nature of the equipment used in the high volume,
test-only facilities that Envirotest designs, constructs and operates for states
that have adopted centralized testing programs, ESP does not manufacture or sell
a material amount of such equipment for the centralized testing market.
 
MANUFACTURING
 
    ESP's manufacturing activities consist primarily of
 
    - materials management, assembly and integration;
 
    - testing and quality control of parts and component subassemblies; and
 
    - final systems testing.
 
    ESP performs these activities in its East Granby, Connecticut facility. ESP
has outsourced the manufacture of substantially all of its subassemblies to
companies who make the component parts pursuant to ESP's proprietary
specifications. This permits ESP's management to focus on ESP's core business.
ESP believes that its outsourcing strategy also enables ESP to concentrate its
financial resources on product development and enhancement by allowing ESP to
maintain a low supply of inventory and to minimize production cost. In addition,
ESP also believes that the outsourced content and modular design of its testing
systems allows for reduced manufacturing cycle times and increased testing
system production. In 1997, ESP's average monthly production was 298 systems,
with each system taking approximately four hours to assemble.
 
    ESP's systems are assembled from components or subassemblies supplied solely
by suppliers who are selected only after ESP has performed significant testing
to ensure that any components or subassemblies used by ESP in its testing
systems can be effectively integrated with ESP's other hardware and software
components or subassemblies. By using quality components and performing such
testing, ESP is able to minimize the number of malfunctions in its systems.
Although many of the components of the testing systems, such as the dynamometer,
are readily available from a number of sources, ESP typically purchases such
components from single suppliers. To date, ESP has not experienced any material
difficulty or delay in obtaining any components or sub-assemblies.
 
SERVICES
 
    ESP provides customers with a one year warranty for its emissions testing
systems. Approximately 85% of ESP's customers enter into a service contract with
ESP for the repair and maintenance of the emissions testing systems following
the warranty period. Service contracts typically have a one year term and the
annual servicing fee is approximately 10% of the purchase price of the related
emissions testing system. ESP's revenues for equipment servicing and maintenance
in 1997 were $14.6 million, or 14.3% of ESP's total revenue for the year.
 
    ESP guarantees to its service program participants that any non-operational
emissions testing system will be fully operational within eight hours of the
time of the initial service call, with the typical time until a system is fully
operational ranging between four and six hours. ESP believes that no other
competitor offers a faster service response time guarantee. The modular design
of ESP's emissions testing equipment also helps to expedite the repair time
because it allows ESP's service technicians to remove and replace a
 
                                       57
<PAGE>
defective part at the customer site. ESP can then repair the defective part at
ESP's facilities, while the customer has full use of an operational system. ESP
has established a customer service network of 149 company-trained direct service
technicians, who account for 54% of ESP's entire workforce. A majority of ESP's
service technicians have been employed with ESP since its formation in 1989.
 
SALES AND MARKETING
 
    ESP markets and sells its emissions testing equipment through both a direct
marketing and sales staff and indirectly through a network of independent sales
representatives and distributors. ESP uses independent sales representatives and
distributors primarily in foreign countries and in connection with the marketing
of emissions testing equipment to states with limited market potential because
of low demand testing equipment. As of September 30, 1998, ESP has a direct
marketing and sales staff of 49 full-time employees and 3 independent sales
representatives and distributors.
 
    Unlike its competitors, which sell a wide variety of tools and other
equipment in addition to emissions testing equipment, ESP focuses solely on
emissions testing equipment. ESP believes this enhances the capabilities and
effectiveness of its sales force. Each member of ESP's marketing and sales staff
receives intensive training in recent developments in Federal, state, and
international legislation and regulation related to air pollution controls, as
well as highly specialized training regarding the design, operation, and
maintenance of ESP's emissions testing equipment. In addition, because states
and municipalities in the United States generally announce their plans to
implement an emissions testing program 12 to 24 months in advance of the
program's implementation date, ESP is able to allocate and relocate necessary
marketing and sales personnel to those states and municipalities so that ESP can
undertake an effective marketing campaign in those locales in advance of the
implementation date.
 
    ESP offers its customers flexible financing and leasing alternatives through
sale and leaseback arrangements. Through a joint venture with Bank of America,
ESP offers leases ranging from 12 to 84 months. Most customers select terms
ranging from 60 to 84 months. The leases offer various purchase options which
permit the customer to purchase the equipment upon expiration of the lease. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Recent Developments."
 
CUSTOMERS
 
    Since 1990, ESP has sold over 10,000 emission testing systems to customers
in 11 states and 4 foreign countries. Substantially all of ESP's customers are
independently owned and operated service stations, automotive repair shops and
dealerships that purchase emissions testing equipment to generate testing
revenue and vehicle repair revenues. No single customer accounts for a material
portion of ESP's sales over the long term. The fees derived by decentralized
facilities from emissions testing generally are substantially in excess of the
cost of owning or leasing emission testing systems. Decentralized facilities
that offer emissions testing also have the opportunity to perform automotive
repairs that are related to emissions test failures as well as other vehicle
repairs and to service vehicles that might not otherwise be serviced at the
facility.
 
COMPETITION
 
    ESP has two principal competitors in the decentralized emissions testing
market: Sun Electric, a division of Snap-on Incorporated, and Automotive
Diagnostics, a division of SPX Corporation. ESP believes that competition in the
decentralized market is based primarily on the following factors: product
performance, ease of use, functionality, reliability and quality; expertise and
customer satisfaction with service and rate of response time; certification by
governmental authorities (with early, and particularly first, certification
being a significant advantage); prior customer relationships; technological
capabilities of the product; and overall cost of the emissions testing
equipment. In the international emissions testing
 
                                       58
<PAGE>
market, ESP typically competes with providers of vehicle emissions testing
equipment on a country-by-country basis. Three of ESP's primary competitors in
Europe are Sun Electric Europe, Robert Bosch GmbH, and Technotest. ESP believes
that the superior quality and innovative features of its emissions testing
systems and the responsive service it provides to its customers will enable it
to maintain its relationships with existing customers and to expand its customer
base both in domestic and international markets.
 
RESEARCH AND DEVELOPMENT
 
    ESP conducts the majority of its research and development at its facility in
Tucson, Arizona. ESP's research and development program employs approximately 23
electrical, software, mechanical and design engineers, approximately 75% of whom
were former employees of United Technologies Corporation and have over 10 years
experience in the vehicle emissions testing industry. ESP's research and
development program is equipped with the latest development tools, including
software engineering tools, mechanical CAD systems, laboratories and a
state-of-the-art test facility. ESP considers research and development to be a
vital part of its operations and dedicates substantial resources to research and
development of product improvements, new products and product applications.
ESP's research and development expenses were approximately $1.4 million in 1995,
$1.7 million in 1996, and $2.3 million in 1997. See "Business-- Facilities."
 
    ESP frequently conducts its technology research and product development
efforts in conjunction with governmental authorities. For example, in 1994, the
California BAR awarded ESP two pilot programs for the development of testing
standards at a test facility in Sacramento, California and, in 1995, New Jersey
awarded ESP a study contract to evaluate alternative emissions testing
procedures and systems.
 
    The experience and expertise of ESP and its employees in the vehicle
emissions testing industry has enabled ESP to develop proprietary technology and
has permitted ESP to respond successfully to technological advances in the
vehicle emissions testing industry. ESP's products are protected by
approximately 20 United States and 25 foreign patents and trademarks. While ESP
believes that its proprietary technology rights are valuable, it also believes
that because of the technological advances in the vehicle emissions testing
industry, factors such as innovative skills, technical expertise and the ability
to adapt quickly to new technologies and government regulation are of greater
competitive significance.
 
EMISSIONS TESTING SERVICES BUSINESS
 
OVERVIEW
 
    Through Envirotest, we are the leading operator of centralized emissions
testing programs in the growing North American vehicle emissions testing market.
Envirotest is the most experienced operator in the approximately $250 million
North American centralized testing market, having tested more than 150 million
vehicles since its inception in 1974. Envirotest currently operates, or is under
contract to operate, 14 of the 21 existing centralized emissions testing
programs in the 16 states that have adopted centralized programs and the only
such program in Canada. Envirotest tested approximately 11.8 million vehicles in
1998, which represented approximately 70% of the total North American
centralized testing market revenues.
 
EMISSIONS TESTING CONTRACTS
 
    Envirotest conducts its centralized testing business under exclusive,
long-term contracts with state, local or other governmental authorities.
Pursuant to these contracts, Envirotest generally
 
    - structures the testing program,
 
    - designs a testing facility network,
 
                                       59
<PAGE>
    - selects, designs and constructs individual inspection and test facilities
      with multiple test lanes,
 
    - designs and installs the required computer network and
 
    - operates the testing program.
 
    Envirotest's emissions testing contracts have an initial term that generally
ranges from five to ten years and may contain options permitting the
governmental authority to extend the contract under similar terms and conditions
for one or more periods of up to two years. A governmental authority may
negotiate renewals or extensions on terms different from those in the initial
contract or expand the program to include additional counties or services.
 
    Envirotest derives most of its contract revenues from its 14 operating
emissions testing contracts with governmental authorities in 10 states and one
Canadian province. Envirotest's five largest state and provincial program
contracts generated approximately 66.9% of its total contract revenues during
the twelve months ended September 30, 1998, with Illinois accounting for 18.0%,
Connecticut for 13.7%, Ohio for 13.0%, Colorado for 12.1%, and Florida for
10.1%. In addition, northern Kentucky recently awarded Envirotest a new
contract.
 
    The table below describes certain contract terms and operating data for each
of Envirotest's existing emissions programs as of September 30, 1998.

(1)  Northern Kentucky contract awarded in June 1998, expected to commence
     operation in 1999.
 
                                       60
<PAGE>
    As of September 30, 1998, Envirotest estimates that it had a contractual
backlog to provide centralized emissions testing services of approximately $873
million through 2008, compared to approximately $936 million at September 30,
1997, approximately $660 million at September 30, 1996, and approximately $724
million at September 30, 1995. Envirotest realized approximately $165 million of
the backlog during the fiscal year ended September 30, 1998. Envirotest
calculates its revenue backlog per contract by multiplying (i) the average
annual test volume, (ii) the fee per vehicle tested, and (iii) the remaining
number of years in the contract term, excluding optional extension periods.
 
    Envirotest believes that, as the incumbent operator in its existing
programs, it generally has a competitive advantage when the programs are rebid,
primarily because Envirotest has already incurred the costs of establishing the
program network and has gained valuable experience in operating the program.
Since 1990, all of Envirotest's emissions testing contracts that provided for
renewal or extension have been renewed or extended beyond their initial terms
except one contract with Maryland that was not material.
 
    The fee which Envirotest receives for each vehicle it tests is based on
Envirotest's bid. Envirotest's bid, in turn, is based on a number of factors,
including the type of test performed under the program, the vehicle population
of a test area, the number of test lanes installed, any volume guarantee, the
cost of labor and real estate, and cost of living adjustment. The governmental
authority sets the frequency at which vehicles must be tested, typically
annually or biennially, and imposes penalties on motorists for noncompliance.
Penalties usually take the form of denial or suspension of vehicle registration.
A governmental entity may, during the term of a contract, request that
Envirotest change the scope of work specified in the contract. These changes may
include an expansion of the geographic area covered by the contract or program
enhancements. Generally the governmental entity pays an additional fee to
Envirotest based on the additional scope of work.
 
    Under most of Envirotest's contracts, the governmental authority has the
right, and in some case may be obligated, to purchase Envirotest's program sites
and facilities upon termination of the contract. The contract usually specifies
that the price is based on either fair market value, book value or actual cost
of the program sites and facilities. We believe that these prices provide
Envirotest adequate compensation for the value of the assets purchased.
 
    Most of these contracts also expressly provide for termination if the
relevant governmental authority repeals the legislation authorizing the
emissions testing program or does not appropriate sufficient funds for the
program. More than half of Envirotest's contracts also allow the governmental
authority to terminate the contract for convenience, upon giving advance written
notice of not less than 30 days. Envirotest believes that it is generally
entitled, either under the express terms of the contract or under applicable
law, to equitable or reasonable compensation for certain costs associated with
the termination of a contract for convenience. Envirotest's contracts also
permit the governmental authority to terminate the contract for cause, generally
after specified notice and cure periods. The repeal of a program or
non-appropriation of funds does not constitute "cause" under such contracts.
 
    In addition, under most of Envirotest's centralized testing contracts,
Envirotest must pay liquidated damages as a penalty if it fails to meet
specified start-up dates or performance requirements, in many cases after a
specified notice and cure period. Liquidated damages provisions are customary in
emissions testing contracts. Some examples of such penalties are
 
    - up to $10,000 a day for late system start-up,
 
    - up to $5,000 per day for inaccurate reports submitted by Envirotest,
 
    - up to ten percent of the fee due to Envirotest for the tests performed for
      submitting incomplete, incorrect, or illegible reports, or
 
    - up to $10,000 per day for failing to allow access to Envirotest's program
      facility or emissions testing data.
 
                                       61
<PAGE>
    At least one contract requires Envirotest to pay liquidated damages if the
state terminates the contract for cause. In fiscal 1998, Envirotest incurred an
aggregate of approximately $0.5 million in liquidated damages under its
contracts with Colorado and Connecticut, compared with $0.7 million in the full
fiscal year 1997. Envirotest is also required to post performance bonds once the
contract is awarded. Those bonds, which range in amount from $100,000 to
$3,000,000, protect the governmental authority for the cost of replacing
Envirotest if the governmental authority terminates the contract for cause prior
to expiration.
 
RECENT DEVELOPMENTS IN CENTRALIZED PROGRAMS
 
    In June 1998, after a competitive bidding process, Envirotest signed a
contract with Kentucky to conduct centralized emissions testing in three
northern counties. Envirotest expects to perform 140,000 tests per year and
generate $23 million over the competing term of the contract. The contract
begins in June 1999 and ends in June 2008.
 
    In June 1997, the Company signed an agreement with Illinois to upgrade the
state's existing centralized vehicle emissions testing program to an enhanced
program. The agreement also extended the program term by nine years, to 2005.
Revenues for the nine-year term are expected to total approximately $385.0
million, including the sum of $48.0 million which the state will pay to
Envirotest during the course of the implementation period for performance of
basic tests and other services provided during this period. Envirotest will
spend approximately $75.0 million to implement the new program. This expenditure
will be partially offset by the $48.0 million to be received from the state.
Enhanced testing will commence in early 1999.
 
    As of March 1997, California elected to terminate, for the convenience of
the state, Envirotest's contract to provide remote sensing services. The
contract was expected to extend through June 30, 1998. The termination was
related to the state's decision to reassess its future vehicle emissions testing
program. On August 15, 1997, Envirotest entered into a Settlement Agreement with
the state resolving the issues related to the termination. Under the terms of
the Settlement Agreement, Envirotest received $2.7 million, including
outstanding receivables.
 
    In December 1995, Envirotest entered into a settlement agreement with
Pennsylvania which awarded Envirotest more than $105 million. This award was
compensation for damages Envirotest incurred when Pennsylvania cancelled a
contract under which Envirotest was supposed to provide centralized testing
services in Pennsylvania. Pennsylvania canceled the contract in reaction to a
change in EPA regulations which allowed Pennsylvania to retain its existing
decentralized program. Envirotest has now received all payments due under the
settlement agreement. Envirotest realized a gain of approximately $21.8 million
on the settlement.
 
CONTRACT AWARD AND PROGRAM IMPLEMENTATION PROCESS
 
    A state or municipality planning to implement a centralized vehicle
emissions testing program generally solicits bids for the right to provide the
testing services. Set forth below is a summary of that competitive bidding
process and the marketing and government relations resources that Envirotest
generally devotes to the bidding process.
 
    PRE-BID MARKETING.  Envirotest considers its participation in the
legislative and regulatory authorization process for emission testing programs
to be an important initial step in marketing its services. Once a government
agency has authorized a centralized contractor-operated program, the government
agency often asks interested parties (including Envirotest and its competitors)
to help draft the technical aspects of a bid request. This effort often includes
reviewing bid criteria and recommending specified test programs. Once drafted,
the bid request is typically revised several times as a result of input provided
by potential bidders and other interested members of the public. Generally, the
bid request establishes several convenience factors such as the average waiting
time and driving distance to a testing station and specifies the technical
requirements of the program.
 
                                       62
<PAGE>
    BID REQUESTS.  Typically, a government agency requests bids through either a
"request for proposal" or an "invitation to bid". In the more commonly used
"request for proposal" process, the government agency evaluates bids on the
following criteria:
 
    - the operating experience, reputation, and financial capability of the
      bidder;
 
    - the bidder's ability to install and operate a technically sophisticated
      testing system in terms of both hardware and software;
 
    - the bidder's ability to integrate testing results with vehicle
      registration information in state computer data systems;
 
    - the bidder's ability to provide additional services (such as safety
      inspections, enhanced diagnostic tests, and mobile testing);
 
    - the bidder's ability to meet specified performance requirements; and
 
    - price.
 
    Because the government agency considers several factors in the "request for
proposal" process, the agency does not necessarily award the contract to the
lowest bidder. In the ITB process, the governmental authority generally conducts
a limited review of a bid to determine if it meets a minimally acceptable
technical standard and generally awards the contract to the lowest-priced
qualified bidder.
 
    BID PREPARATION PROCESS.  Envirotest has developed a sophisticated
optimization model that it uses to design the most efficient program network for
any given set of program requirements. The model assists Envirotest in designing
a network that provides the greatest convenience and fastest rate of testing
with the fewest number of testing locations. Envirotest has also developed a
sophisticated costing model, which assists Envirotest in predicting the
engineering, development, construction and operating costs of a proposed
program. In using the costing model, Envirotest takes into account the real
estate, construction, labor, equipment and other costs that may be unique to a
specific geographic region or program.
 
    CONTRACTOR SELECTION AND NEGOTIATION.  After the submission of bids by
competing bidders, the governmental authority selects one contractor and the two
parties begin negotiations regarding a contract. The "request for proposal" and
the bid submitted by the selected contractor contain the main terms of the
contract. The time period between bid submission and award is generally between
one to three months.
 
    PROGRAM IMPLEMENTATION.  Once Envirotest and the governmental authority
enter into a contract, Envirotest begins the process of purchasing or leasing
real estate, constructing the program facilities, and developing and installing
the necessary hardware and software. This process generally takes six months to
two years to complete, depending on the size of the network. A typical facility
consisting of an office and four test lanes costs an average of approximately
$1.5 million to $2.0 million to acquire, build and equip. Approximately six
months prior to the anticipated commencement of testing, Envirotest begins a
media campaign to educate the public about the new program. At the same time,
Envirotest also begins to hire and train its workers.
 
    A start-up team implements each program. The team consists of a program
manager, who is responsible for communicating with the governmental authority
and for managing Envirotest's operations under the contract, station managers,
who are responsible for the individual operation of each station, and other
support staff. Once Envirotest implements the program, its senior management
monitors the operation of the program on an ongoing basis.
 
    Prior to the expiration of a contract term, Envirotest and the government
agency generally discuss the possibility of an extension or renewal of the
contract and the principal terms of any such extension or renewal. Depending on
the program's enabling legislation, the governmental authority may either extend
the contract or begin a new competitive bidding process. Since 1990, all of
Envirotest's emissions testing
 
                                       63
<PAGE>
contracts that provided for renewal or extension have been renewed or extended
beyond their initial terms except for the Maryland contract, which was not
material. In the cases in which a state has begun a new competitive bidding
process, Envirotest has either made the winning bid or has been the only company
to bid.
 
SOFTWARE AND RELATED TESTING EQUIPMENT
 
    Envirotest has developed sophisticated proprietary computer software and
hardware that is essential to the efficient operation of its centralized testing
facilities. Central host computers and various peripheral devices located at
each program's headquarters monitor each of Envirotest's inspection lanes and
process and permanently store vehicle test histories.
 
    SOFTWARE.  Envirotest believes that its ability to develop program-specific
software is important to the efficient operation of its testing facilities.
Envirotest has devoted significant efforts to its development of software
systems which enable it to conduct highly automated and rapid tests.
Envirotest's software has allowed it to automate most of the important functions
of the testing process, including applying the appropriate emissions standards
against which vehicles are tested. These standards vary by manufacturer, model
and year. Envirotest's lane operators are prompted with step-by-step
instructions for performing the tests and processing the results. Envirotest is
using its expertise in this area to develop new software systems for its
enhanced programs.
 
    TESTING EQUIPMENT.  Envirotest's computer-managed inspection systems control
the automated inspection of a motor vehicle based on identifying characteristics
such as make, model, year and engine size. The inspection process usually
includes multiple tests at multiple testing stations that are designed for
specialized functions and are serviced by computers, specialized test equipment
and associated applications software. Envirotest also uses a variety of data
entry devices such as optical-code and bar-code readers, and various test
equipment such as dynamometers and emissions measurement systems. Envirotest
chooses from a number of equipment suppliers to meet the requirements of a
specific system design, depending on applicable specifications and pricing.
Specialized hardware, software and engineering are combined to provide a highly
automated inspection systems with an emphasis on test data integrity and a rapid
rate of operation. Envirotest acts as a systems integrator and does not
manufacture any hardware. However, Envirotest does design specialized hardware.
 
REMOTE SENSING DEVICES
 
    Envirotest sees a potential growth opportunity in the development of remote
sensing technology. In 1991, Envirotest entered into a Development and Exclusive
Licensee Agreement with the University of Denver and two University of Denver
research scientists pursuant to which Envirotest acquired the exclusive right to
manufacture and market a remote sensing device system. The device is used to
monitor carbon monoxide, carbon dioxide, and hydrocarbons emitted from a moving
vehicle. The remote sensing technology measures vehicle emissions from as many
as 1,500 vehicles per hour and photographs the subject vehicle to record its
license plate number. The term of the license runs until the later of 2016 or
the expiration of the last patent included in the license. In exchange for these
rights, Envirotest must pay a 10% royalty on gross receipts from sales and
leases of devices which incorporate the licensed technology or software, and
$.25 on each vehicle Envirotest tests by means of such device.
 
    Envirotest has conducted pilot demonstration programs or studies of remote
sensing technology for several governmental entities, including a pilot program
in May 1998 for the City of New York. Envirotest has also leased remote sensing
units to companies in Taiwan for use in a study there. On August 29, 1997,
Envirotest purchased a remote emissions sensing product line from Hughes
Aircraft Company and acquired or obtained a long term royalty-free license to
the related technologies for $3.7 million. In addition, Envirotest agreed to pay
a 3% royalty on future net revenues related to remote sensing sales and
 
                                       64
<PAGE>
services over the next five years up to a cap of $10.0 million. Envirotest also
assumed Hughes' contract with Arizona to provide remote sensing services.
 
ADDITIONAL GROWTH OPPORTUNITIES
 
    Envirotest offers a variety of program enhancements, including on-road
testing, safety inspection and vehicle registration services. These program
enhancements offer governmental authorities and motorists the convenience of
multiple vehicle certification services at a single location. Once its network
of emissions testing facilities are in place, Envirotest is able to offer these
services for an additional fee without incurring significant additional costs.
However, the market for these services is presently small.
 
    SAFETY INSPECTION SERVICES.  Envirotest designs and implements
highly-automated vehicle safety inspection systems that test the safety features
of vehicles such as brakes, headlight alignment and intensity, front and rear
chassis alignment, shock absorber performance, steering system integrity, noise
level, tire condition, safety belts, mirrors, and glass. Envirotest has provided
fully-automated safety inspection services at its testing facilities in
Connecticut and Florida. Envirotest has a contract with Connecticut to provide
safety inspection services in that state to an estimated 160,000 vehicles
annually. In addition, Envirotest has designed and currently maintains a
state-of-the-art facility for inspection of New York City taxicabs and
limousines. Envirotest also inspects the taxicab fleet in the City of Miami on
behalf of Dade County, Florida.
 
    Envirotest's existing centralized testing infrastructure and its expertise
in safety inspection testing equipment and procedure put it in a favorable
competitive position if centralized safety inspections are mandated in the
future in states in which it conducts centralized emissions testing. The
National Highway Transportation Safety Administration has stated that it favors
the adoption of periodic safety inspection programs. The award by Connecticut of
a safety inspection contract to Envirotest demonstrates the states' potential
interest in providing their residents with the convenience of safety and
emissions testing services in one location.
 
    VEHICLE REGISTRATION SERVICES.  Envirotest has developed software which
allows it to access motor vehicle records, so that it can offer consumers the
convenience of vehicle registration as part of the emissions testing process.
Wisconsin and certain other states required bidders for their emissions testing
programs to include a proposal for conducting vehicle registration services in
the emissions inspection lanes. In 1997, Wisconsin asked Envirotest to
demonstrate a pilot registration program at one station. Based on the success of
this demonstration, the state has requested Envirotest to provide the service at
five additional stations. Although no assurance can be given as to whether other
states will include vehicle registration services in their programs, Envirotest
anticipates that there will be increasing state interest in the performance of
registration services in the test stations.
 
    ANCILLARY SERVICES.  Envirotest is investigating ancillary service
opportunities that complement its core business. The opportunities will use
Envirotest's existing infrastructure and operating assets. Envirotest executed a
contract with an agency to sell advertising space and design a direct marketing
campaign for its customers at certain of its existing emissions testing
programs. Envirotest also signed a contract to provide vehicle data from certain
of its existing emissions testing programs to a third party. The revenue from
these two contracts is not material to Envirotest at present.
 
COMPETITION
 
    The market for contractor-operated emissions testing programs is highly
competitive. Envirotest typically competes against numerous bidders for new or
renewal contracts.
 
    Envirotest's principal domestic competitors include Gordon-Darby, Inc. and
MARTA Technologies, Inc. Gordon-Darby operates four programs, testing
approximately 3.9 million vehicles per year. MARTA has contracts to operate
three programs, testing approximately 2.3 million vehicles annually.
 
                                       65
<PAGE>
MARTA is wholly-owned by The Allen Group, which has recently announced its
intention to sell MARTA. Envirotest also competes with several other domestic
and foreign companies who choose to bid from time to time on select programs.
 
OPPORTUNITIES IN INTERNATIONAL MARKETS
 
    We believe the international market represents a significant growth
opportunity, especially in light of our ability to offer products and services
for both the centralized and decentralized markets. We estimate that there are
629 million motor vehicles currently located in Europe, Asia and North, Central
and South America. This is over seven times the estimated 90 million vehicles in
the United States and Canada subject to emissions testing. We intend to expand
aggressively internationally by offering a broad range of vehicle emissions
testing equipment and services to countries and other jurisdictions around the
world that are, in our view, likely to adopt vehicle emissions testing programs
similar to those adopted in the United States. We plan to offer advisory
services to these countries at the early stages of their program development,
thereby positioning us to become the provider of choice for both centralized and
decentralized programs. We believe that the international community will
continue to look to the United States, and especially the California BAR, for
technical guidance on emissions testing programs. In recent years,
representatives from the following countries have toured ESP's emissions test
lane at the California BAR facility in Sacramento, California: Australia,
Canada, Germany, Japan, Mexico, New Zealand, Philippines and Taiwan. We believe
that there are significant market opportunities in the certain countries which
have implemented emissions testing programs or which have announced or are
considering the implementation of such programs, particularly Canada, Germany,
Mexico, Australia and the United Kingdom.
 
    Envirotest currently operates Canada's only centralized emissions testing
program through its Canadian subsidiary, Envirotest Canada. We also see a
significant emerging market for emissions and safety testing in South and
Central America and the Asia-Pacific region, and we are currently evaluating bid
opportunities with local parties in several of these areas. In November 1997,
Envirotest's Argentine joint venture partner was awarded a 15-year contract for
the safety and emissions testing program in the Province of San Luis, Argentina.
The joint venture will compensate Envirotest for implementation services and
delivery of the testing system for the San Luis program and Envirotest will
receive a royalty per test. However, the total royalties will not be material to
Envirotest.
 
    In 1997, Chemonics International, Inc. awarded Envirotest a four-year
subcontract valued at approximately $1.8 million to design the vehicle emissions
test program for the USAID Cairo Air Improvement Project. Envirotest has also
completed several other international projects in recent years. In 1995,
Envirotest installed a state-of-the-art demonstration lane in Mexico City,
Mexico. In 1996, Envirotest built four heavy duty vehicle emissions and safety
lanes for the Government of India. In 1986, Envirotest developed and installed a
safety and emissions testing system with 26 inspection lanes in Taiwan.
 
FACILITIES
 
    ESP leases all its facilities. The remaining lease terms range from one
month to four years. ESP's executive offices and its manufacturing, warehouse
and principal marketing and sales facility are located in East Granby,
Connecticut, in two buildings occupying a total of approximately 35,600 square
feet. These two buildings are leased through March 31, 2002. ESP's primary
research and development and engineering facility is located in Tucson, Arizona,
in one building occupying approximately 9,760 square feet. It is leased through
July 2001. ESP also has 17 sales and service offices located in nine states and
in Canada, Germany and Mexico.
 
    Envirotest designs, builds and equips its testing sites to meet each
program's specific requirements. Envirotest's testing sites typically range from
one to three acres, depending on the number of testing lanes, specific equipment
requirements and lot configuration. Envirotest currently owns 128 testing
stations and leases 48 testing stations totaling in excess of 1,200,000 square
feet. Envirotest also maintains a program
 
                                       66
<PAGE>
headquarters in each of the states in which it operates. Envirotest's
engineering staff occupies 40,000 square feet of leased space in Tucson,
Arizona. Envirotest also has executive offices in Bethesda, Maryland.
 
    In the near future, Envirotest plans to move its executive offices to the
East Granby facility and to close the Bethesda offices. In addition, ESP and
Envirotest will integrate their research and development groups into one of the
two Tucson facilities, and will close the other.
 
    We believe our current facilities are in good condition and adequate to
support our current operations, but we plan to open additional sales and service
offices to support continued growth and expansion both domestically and
internationally. We currently anticipate that we will be able to renew the
leases that are scheduled to expire in the next few years on terms substantially
similar to those currently in effect.
 
EMPLOYEES
 
    We believe that the knowledge, skills and experience of our employees are
key components of our success. As of September 30, 1998, ESP had 275 employees,
of which 149 were in its service organization, 49 were in marketing and sales,
32 were in production and manufacturing, and 23 were in research and development
and engineering. 75% of ESP's employees have more than eight years of experience
in the emissions testing market and 40% have college and/or advanced degrees.
None of ESP's employees is represented by a labor union and ESP has not
experienced any work stoppages. ESP believes that its employee relations are
good.
 
    As of September 30, 1998, Envirotest had 3,374 employees, of which 1,411 are
full-time and 1,936 are part-time employees. None of Envirotest's domestic
employees is represented by a labor union. Of the 206 employees employed
(through Envirotest Canada) in the British Columbia program, 191 are represented
by a labor union under the terms of a collective bargaining agreement that
expires on August 31, 1999 (the termination date of Envirotest's contract in
British Columbia). Although there were strikes at the British Columbia program
in 1992 and 1996, Envirotest believes that its employee relations are currently
good.
 
LEGAL PROCEEDINGS
 
    On September 26, 1995 Ganzcorp Investments, Inc. d/b/a/ Mustang Dynamometer
filed suit against Envirotest Systems Corp. in U.S. District Court for the
Northern District of Ohio. The suit alleged breach of contract and asked for
damages in excess of $10.0 million. The suit was voluntarily dismissed by the
parties on December 22, 1995 so that the parties could focus on settlement
negotiations. On October 8, 1997, the case was re-filed by Ganzcorp when
settlement negotiations broke down between the parties. In 1993, the parties
signed an agreement for the supply of chassis dynamometers by Ganzcorp to the
Company for its emission testing programs in Ohio, Connecticut, and
Pennsylvania. When the Company's testing program with the State of Pennsylvania
was canceled, the Company canceled its contract with Ganzcorp per a "termination
for convenience" clause. Under such clause Ganzcorp would be allowed to make a
claim for certain costs incurred but such a claim would be substantially below
its stated claim of more than $10,000. Additionally, the Company has
counterclaims against Ganzcorp for breach of contract and warranty obligations
which it believes to be in excess of $7,900. Subsequent to September 30, 1998,
the Company has agreed in principal to pay Ganzorp up to $1.5 million in
settlement of all of the above claims. The settlement amount has been included
in the accompanying financial statements within the balance sheet caption
"accrued expenses and other current liabilities."
 
    R.W. Granger & Sons filed a Demand for Arbitration in the East Hartford,
Connecticut, office of the American Arbitration Association in September 1996.
The demand alleged that Envirotest breached a contract with Granger and failed
to pay amounts due Granger in connection with the construction of certain of
Envirotest's testing facilities in the State of Connecticut. On December 29,
1997, Granger filed a complaint in State Superior Court in the Judicial District
of Hartford/New Britain at New Britain alleging
 
                                       67
<PAGE>
that Envirotest's failure to pay amounts due to Granger is an unfair trade
practice under the Connecticut Unfair Trade Practices Act. The arbitrators
awarded Granger approximately $495,000, including the costs of the arbitration,
in a decision rendered on August 12, 1998. Granger had claimed damages of
approximately $2.0 million in its Demand for Arbitration. Envirotest intends to
defend vigorously against Granger's remaining claim in State Superior Court. We
believe that any judgment against Envirotest with respect to the remaining claim
will not have a material adverse effect on our business, financial condition and
results of operations.
 
    On November 22, 1997, the Denver District Court granted Envirotest's motion
to dismiss a class action complaint filed by Timothy Dore on behalf of all
persons who paid to have a vehicle tested in Envirotest's metro Denver
facilities from January 2, 1995 to present. The complaint alleged breach of
contractual obligation to the class and the negligent performance of emissions
testing under Envirotest's contract with the State of Colorado. On January 6,
1998, Dore filed an appeal in the Colorado Court of Appeals from the trial
court's order of dismissal. On June 1, 1998 Dore filed a motion to dismiss the
appeal and on June 15, 1998 the Colorado Court of Appeals granted the motion to
dismiss the appeal with prejudice. On June 1, 1998, the attorneys for Dore filed
a new class action complaint in the Boulder District Court. The new complaint
has replaced Timothy Dore with two new representative plaintiffs, Jay Sherrit
and Arthur D. Gonzales, and the new complaint is brought on behalf of virtually
the identical class. Although the new complaint purports to state a new cause of
action, it alleges claims for breach of contract and negligence which are
similar to Dore's class action complaint. On June 23, 1998 Envirotest filed a
motion to change venue to the Denver District Court. Envirotest intends to
defend vigorously against the plaintiff's claims. We believe that any judgment
obtained against Envirotest will not have a material adverse effect on our
business, financial condition and results of operations.
 
    On November 18, 1998, Timothy J. Grendell, on behalf of himself and all
others similarly situated, filed a class action lawsuit in the Court of Common
Pleas, Summit County, Akron, Ohio. The defendants include the Ohio Environmental
Protection Agency and the Company. Grendell filed a virtually identical suit in
1996 and it was dismissed without prejudice exactly one year before the
above-noted class action lawsuit was filed. Like the 1996 lawsuit, the
above-noted class action lawsuit asserts that the statute and contract that
created E-Check are unconstitutional under Ohio law, and requests declaratory
and injunctive relief, attorney fees and costs. We believe that we have valid
defenses to the claims contained in the complaint and we intend to defend the
matter vigorously.
 
    In addition to the above, we are a party to various other legal proceedings
and claims in the ordinary course of business. Although the claims cannot be
estimated, in our opinion the resolution of these matters will not have a
material adverse effect on our business, financial condition and results of
operations.
 
ENVIRONMENTAL MATTERS
 
    Our operations are subject to federal, state and local environmental laws
and regulations relating to the protection of human health and the environment
and the handling and management of hazardous materials. We believe that we are
in substantial compliance with all applicable environmental laws and regulations
and that the costs of compliance are not material to us.
 
    The Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, and similar state superfund statutes generally impose joint
and several liability on present and former owners and operators for remediation
of contaminated properties regardless of fault. At a number of the properties
that we own, former owners and operators may have released hazardous materials
on or under such properties in connection with their operations. We do not have
sufficient information to estimate its potential liability, if any, in
connection with any potential contamination from historical operations at such
properties.

INTELLECTUAL PROPERTY
 
    We regard our patents, copyrights, trade secrets, trademarks and similar
intellectual property as important to our success. We depend upon a combination
of patents, trade secrets, copyright and trademark laws, license agreements,
nondisclosure and confidentiality agreements with our employees, customers and
others and various security measures to protect our proprietary rights. Although
our success and competitive position in the market depends to a great extent on
our ability to exploit and protect our proprietary intellectual property rights,
apart from the "ENVIROTEST" and "ESP" trade names, we do not believe that any
single patent, copyright, trade secret, or trademark is material to our
business.
 
    We believe we own or license from third parties the intellectual property
rights in substantially all of our material products and services. We have not
received notice of any claim, which we believe is valid, that our products or
services infringe upon another party's intellectual property. Given the
technological complexity of our products and services, however, there can be no
assurance that claims of infringement will not be asserted against us or against
our customers in connection with their use of our systems or products, nor can
there be any assurance as to the outcome of any such claims.
 
    We own, either individually or jointly with a third party, approximately 35
U.S. and foreign patents and are actively prosecuting approximately 25 patent
applications in the U.S. and abroad covering a variety of inventions in the
vehicle emissions testing equipment and services field. Our patents have
expiration dates ranging from 1998 through 2017. Patents cannot be renewed or
extended. We also pursue the registration of our trademarks in the United States
and internationally, and have applied for or obtained registrations for certain
products and services, including ENVIROTEST, SMOG DOG, AUTOSENSE, and SYSTEM
ONE. Trademarks can have a perpetual existence so long as they continue to be
used on substantially the same products and services and the appropriate steps
are taken with respect to maintaining the registrations in effect.
 
    Envirotest claims copyright protection in its proprietary software programs.
Such protection extends to the source code and can also protect certain visual
aspects of the programs from copying. However, such protection does not preclude
others from creating programs which perform the same function.
 
    We are party to a number of technology and software licenses pursuant to
which we have obtained the rights to use third party technology in our business.
Our most material licenses include those with the University of Denver and
Hughes Aircraft relating to the remote emissions sensing technology.

EXECUTIVE COMPENSATION
 
    In October 1998, we entered into employment agreements with Messrs. McKenna,
Tedeschi, Webb and Langevin. The employment agreements replace previous
employment agreements between such individuals and ESP. The employment
agreements provide for an initial term of three years and for payment of a base
salary and incentive compensation. All such agreements provide for the grant to
such individuals of nonqualified stock options in EnviroSystems Corp. with an
exercise price equal to the fair market value of common stock in EnviroSystems
Corp. Such agreements also provide for severance payments in the event that we
terminate the executive's employment for reasons other than for cause or
incapacity and in the event that the executive elects to terminate his
employment upon a change in control of the company. In the event that we
terminate the executive's employment for reasons other than for cause or
incapacity (or in the event the executive elects to terminate his employment
upon a change of control of the company), the executive shall be entitled to
receive from us his salary, incentive compensation payments, and benefits in
accordance with his employment agreement through the last date of his employment
and a lump sum severance payment in an amount equal to the greater of (a) one
year's base salary or (b) the base salary payable during the unexpired term of
the agreement. Each executive agrees that he will not compete with us for a
period of six months following his termination of employment if such termination
is for any reason other than termination by the executive following a change in
control of the company or termination of the executive by us without cause. If
the executive terminates his own employment following a change of control or if
we terminate him without cause, the executive agrees that he will not compete
with us during the period for which he receives severance payments. The
agreements also include confidentiality commitments.
 
    The following table summarizes the compensation paid by ESP and Envirotest
to each of their Chief Executive Officers and to each of the other three most
highly compensated executive officers of ESP and Envirotest. Information with
respect to ESP executive officers is given for the year ended December 31, 1997.
Information with respect to Envirotest executive Officers is given for the
fiscal year ended September 30, 1998. ESP did not have any pension plan or a
long-term incentive plan, did not issue any restricted stock awards and did not
grant any stock options during 1997.

                              CERTAIN TRANSACTIONS
 
REORGANIZATION
 
    We were incorporated in Delaware on March 12, 1998. Prior to the
consummation of the acquisition of Envirotest and the related transactions, we
had no outstanding shares of capital stock and ESP was an indirect wholly owned
subsidiary of Newmall. In April 1996, ESP was acquired by a wholly owned
subsidiary of Wellman plc, a then-publicly incorporated United Kingdom company.
In January 1998, Wellman plc was acquired by Newmall plc, a United Kingdom
public limited company that was controlled by Alchemy. Alchemy Investment Plan
is an investment consortium principally composed of United States institutional
investors that is advised by Alchemy Partners. In contemplation of the
acquisition of Envirotest and the related transactions, in May 1998, Newmall plc
divested itself of all of its holdings except for Wellman North America, Inc.
and its subsidiaries, which included ESP. Newmall plc reorganized as Newmall
Limited, a United Kingdom private limited company whose controlling shareholder
remains Alchemy.
 
    As part of the acquisition of Envirotest and the related transactions,
EnviroSystems and our company reorganized in a manner to:
 
    - cause the shareholders of Newmall to acquire 82.5% of the shares of
      EnviroSystems; and
 
    - cause us to become a wholly owned subsidiary of EnviroSystems.
 
    This reorganization took place in several steps. First, the Newmall
shareholders capitalized us with cash (pro rata to their Newmall shareholdings),
receiving in exchange 95% of the shares that we ultimately issued as part of the
reorganization. Next, the Newmall shareholders transferred their Newmall shares
to us and, in exchange, were issued the remaining 5% of the shares issued as
part of the reorganization. At this stage, the former shareholders of Newmall
owned 100% of our shares (and in the same proportion as their Newmall
shareholdings) and we owned 100% of the shares of Newmall. Each of the former
Newmall shareholders then transferred its shares of our company to EnviroSystems
in exchange for shares in our company (at which point, the former Newmall
shareholders owned 100% of the EnviroSystems shares and EnviroSystems held 100%
of our shares). Immediately thereafter, we issued additional shares to the
Noteholders so as to cause them, in the aggregate, to hold 17.5% of the
EnviroSystems shares and the former Newmall shareholders to hold 82.5% of the
EnviroSystems shares.
 
    Further, as part of the acquisition of Envirotest and the related
transactions, we acquired 76.5% of the shares of Envirotest. The remaining 23.5%
was held by ESP. Subsequent to the consummation of the acquisition of
Envirotest, we acquired from ESP the Envirotest shares it held so that
Envirotest became our direct, wholly owned subsidiary. ESP remained an indirect
wholly owned subsidiary of our company.
 
SUBSCRIPTION AGREEMENTS
 
    Prior to the acquisition of Envirotest and the related transactions, Messrs.
McKenna and Tedeschi entered into an agreement with Newmall and ESP under which
Newmall granted to each of such individuals 840,000 of its ordinary shares in
consideration of such individual's agreement to terminate a previously existing
management bonus agreement between ESP and such individual. Subject to certain
exceptions, including transfers among themselves and any exchange of the
ordinary shares for shares of our common stock, Messrs. McKenna and Tedeschi
have agreed, for a period of one year from the effective date of the agreement,
not to sell, assign, exchange, transfer, distribute or otherwise dispose of any
of the ordinary shares they receive. Under the terms of the agreement, prior to
any initial public offering of Newmall's ordinary shares or our common stock, or
any "change of control" of Newmall or our company, such individuals also granted
to each other a right of first refusal such that if one individual wishes to
sell his shares, the other individual shall have the right to acquire these
shares at fair market price.

    In addition, in October 1998, Mr. Langevin entered into an agreement with
Newmall and ESP under which Newmall granted to Mr. Langevin 210,000 of its
ordinary shares in consideration of his services as an employee of ESP. Subject
to certain exceptions, including transfers to Messrs. McKenna and Tedeschi, and
any exchange of the ordinary shares for shares of our common stock, Mr. Langevin
agreed not to sell, assign, exchange, transfer, distribute or otherwise dispose
of the shares he receives for one year from the effective date of the agreement.
Under the terms of the agreement, prior to any initial public offering of
Newmall's ordinary shares or our common stock, or any "change of control" of
Newmall or our company, Mr. Langevin also granted to Messrs. McKenna and
Tedeschi a right of first refusal such that if Mr. Langevin wishes to sell his
shares, Messrs. McKenna and Tedeschi shall have the right to acquire such shares
at fair market price.
 
    In addition, under the agreements, each of Messrs. McKenna, Tedeschi and
Langevin agrees that in the event Newmall or our company enters into an
underwriting agreement in connection with an initial public offering of the
ordinary shares or our common stock pursuant to a registration statement under
the Securities Act, each of such individuals will execute an agreement that for
a period of up to 180 days following the effective date of such registration
statement, each of such individuals will not, without the prior written consent
of the lead underwriter of the initial public offering, offer, pledge, sell,
contract to sell, grant any option for the sale of, or otherwise dispose,
directly or indirectly;
 
    - any of the ordinary shares they receive;
 
    - any shares of our common stock they receive upon an exchange of such
      ordinary shares; or
 
    - any other securities of Newmall or our Company convertible into,
      exercisable for, or exchangeable for common stock or other shares of
      Newmall or our Company.
 
OTHER TRANSACTIONS
 
    The issuances of shares of Newmall and our Company to Messrs. McKenna,
Tedeschi and Langevin under the agreements described above occurred prior to the
reorganization. Therefore, in connection with the reorganization, Messrs.
McKenna, Tedeschi and Langevin became shareholders of EnviroSystems. For more
information see the "Security Ownership" section of this prospectus.

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
SENIOR SECURED CREDIT FACILITY
 
    The following description briefly outlines the provisions of our senior
secured credit facility. We have filed a copy of the senior secured credit
agreement as an exhibit to the registration statement which includes this
prospectus.
 
    The description set forth below is not complete and is qualified in its
entirety by reference to certain agreements setting forth the principal terms
and conditions of our senior secured credit facility.
 
    On October 16, 1998, we entered into a credit agreement among our company,
EnviroSystems Corp., the lenders party thereto, Credit Suisse First Boston as
Administrative and Collateral Agent, DLJ Capital Funding, Inc. as Syndication
Agent and Credit Suisse First Boston and Donaldson, Lufkin & Jenrette Securities
Corporation, as Arrangers.
 
    The Company's senior secured credit facility consists of:
 
    - term loan facilities of $385 million, consisting of a Term Loan A facility
      of $175 million, maturing approximately five and a half years after
      funding; and a Term Loan B facility of $210 million, maturing
      approximately seven years after funding; and
 
    - a revolving loan facility for revolving borrowings of up to $50 million
      and maturing approximately five and one half years after funding of the
      Term Loan Facility.
 
    Loans under the senior secured credit facility bear interest at a floating
rate equal, at our option, to either:
 
    - the base rate (as defined below) plus a certain additional percentage per
      year; or
 
    - LIBOR (as defined below) plus a certain additional percentage per year.
 
    The term "base rate" means the higher of:
 
    - the prime lending rate of Credit Suisse First Boston in effect from time
      to time; or
 
    - the federal funds effective rate plus 0.5%.
 
    For base rate loans, the additional percentage is as follows:
 
    - for Term Loan A and the revolving loan facility, the additional percentage
      varies between 1.25% and 2.50% depending on the leverage ratio of our
      company and its subsidiaries; and
 
    - for Term Loan B, the additional percentage is 3.00%.
 
    The term "LIBOR" has a market-standard definition reflecting the rate
established daily in the London interbank market for Eurodollar funds adjusted
for required reserves.
 
    For LIBOR loans, the additional percentage is as follows:
 
    - for Term Loan A and the revolving loan facility, the additional percentage
      varies between 2.25% and 3.50% depending on the leverage ratio of our
      company and its subsidiaries; and
 
    - for Term Loan B, the additional percentage is 4.00%.
 
    Interest on base rate borrowings is payable quarterly in arrears and
interest on LIBOR borrowings is payable at the end of the relevant interest
period (but at least quarterly).
 
    Amounts owed under the senior secured credit facility will be our direct
obligations. They will be unconditionally guaranteed by EnviroSystems, each of
our existing and subsequently acquired or organized domestic subsidiaries
(including ESP and Envirotest) and certain of our foreign subsidiaries.
 
                                       76
<PAGE>
    Our obligations under the senior secured credit facility are secured by a
first priority, perfected security interest in:
 
    - substantially all of our tangible and intangible assets (other than the
      assets of Envirotest in Ohio); substantially all of the assets of each of
      our existing and subsequently acquired or organized domestic subsidiaries
      and certain foreign subsidiaries of the Company; and
 
    - all of EnviroSystems' equity interest in our Company.
 
    The term loan facility provides for mandatory prepayments, in amounts not
less than:
 
    - 75% (or if our leverage ratio is less than or equal to 3:1, then 50%) of
      consolidated excess cash flow, as such term is defined in the senior
      secured credit facility;
 
    - 100% of the net cash proceeds of all non-ordinary course of business asset
      sales by EnviroSystems or the Company and its subsidiaries (including
      insurance and condemnation proceeds), subject to certain exceptions for
      reinvestment in certain assets within 270 days;
 
    - 100% of the net cash proceeds of issuances of debt obligations of
      EnviroSystems or the Company and its subsidiaries other than issuances of
      debt expressly permitted by the senior secured credit facility (including
      the Notes and the senior discount notes of EnviroSystems); and
 
    - 100% of the net cash proceeds of issuances of equity securities of
      EnviroSystems or the Company and its subsidiaries, subject to certain
      exceptions.
 
Mandatory prepayments shall be made without premium or penalty, except in the
case of Term Loan B. Term Loan B shall be prepayable during the first and second
year following the Issue Date at a premium equal to 101% of the aggregate
principal amount to be prepaid and thereafter, without premium or penalty.
However, mandatory prepayments are subject to breakage costs and actual
reemployment costs. Mandatory prepayments will be applied to Term Loans A and B,
in each case PRO RATA to the remaining amortization payments of such loans.
However, holders of Term Loan B may elect to have their portion of any mandatory
prepayment applied to any outstanding portion of Term Loan A.
 
    The senior secured credit facility contains customary representations and
covenants for facilities of this type, as well as others agreed upon by our
company, DLJ and CSFB. These covenants include (but are not limited to)
financial maintenance covenants and limitations on:
 
    - additional debt;
 
    - liens;
 
    - investments;
 
    - sale and leaseback transactions;
 
    - sales of assets;
 
    - mergers and acquisitions;
 
    - dividend payments and stock repurchases;
 
    - capital expenditures;
 
    - prepayments of senior debt and subordinated debt;
 
    - changes in business conduct; and
 
    - capital expenditures.
 
    The senior secured credit facility contains typical events of default,
including, without limitation:
 
    - the failure to pay principal when due;
 
                                       77
<PAGE>
    - the failure to pay any interest when due (including the applicable cure
      period);
 
    - failure to perform, or breach of, any covenant;
 
    - the occurrence of any cross-default and cross-acceleration;
 
    - the imposition of any material judgments
 
    - the occurrence of changes of control;
 
    - the occurrence of certain events involving bankruptcy or insolvency; and
 
    - the invalidity of any guarantees or security agreements.
 
OHIO NOTES
 
    In April 1995, Envirotest issued to the Ohio Air Quality Development
Authority $64.38 million original principal amount of its senior secured notes
(the "Ohio Notes"), $53.1 million of which were outstanding as of September 30,
1998. Envirotest used the proceeds of the Ohio Notes to finance the development
of the vehicle emission test stations it operates in Ohio. The Ohio Notes are
secured by Envirotest's interest in such stations and the assets related to such
stations. These Ohio assets include, without limitation, the land, buildings and
equipment used at such stations; and the gross revenues of such stations.
 
    The Ohio Notes are currently supported by a letter of credit issued under
the Company's senior secured credit facility. The Ohio Notes (and the collateral
for those notes) in turn secure the Ohio Air Authority's Air Quality Revenue
Bonds, Series 1995 which were sold to investors in a private placement. Such
bonds have the same economic terms as the Ohio Notes.
 
    The final maturity date of the Ohio Notes is December 31, 2005. Principal of
the Ohio Notes is repayable in sinking-fund installments on the first day of
each month. The monthly installment is $440,000 for September 1998 and is
scheduled to increase to $800,000 by the final maturity date. In addition,
principal on the Ohio Notes is subject to mandatory prepayment in the event the
relevant Ohio vehicle emissions testing program is terminated by law or
discontinued and Envirotest (or the developer of the stations) receives
compensation from the State of Ohio for such termination or discontinuation.
Voluntary repayments of the Ohio Notes are permitted subject to the payment of a
yield maintenance premium.
 
    Interest on the Ohio Notes accrues at a per annum rate of 8.10%, and is
payable on each monthly principal repayment installment date.
 
    The Ohio Notes contain covenants and events of default that are customary
for transactions of this type, including limitations on consolidations, mergers
and other fundamental changes involving Envirotest and limitations on further
liens on the collateral securing the Ohio Notes.
 
ENVIROSYSTEMS SENIOR DISCOUNT NOTES
 
    On October 16, 1998, EnviroSystems issued $207.0 million aggregate principal
amount of its 15% Senior Discount Notes due 2009. These senior discount notes
are unsecured senior obligations of EnviroSystems and will mature on October 31,
2009. These senior discount notes bear interest at a rate of 15% per year.
Interest on these senior discount notes will accrue and be payable semiannually
on April 30 and October 31 of each year beginning on the date of issuance, but
will not be payable in cash prior to April 30, 2004. Interest on these senior
discount notes will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from the date of issuance.
 
    EnviroSystems may redeem these senior discount notes, in whole or in part,
at any time or on various occasions upon not less than thirty nor more than 60
days' notice to holders of these senior discount notes. The redemption price of
these senior discount notes is equal to the percentages of the principal amount
of
 
                                       78
<PAGE>
these senior discount notes set forth below, plus accrued and unpaid interest to
the redemption date, if redeemed during the 12-month period beginning October 31
of the years indicated below (or, in the case of 1998, commencing on the date of
issuance).

    Upon the occurrence of certain change of control situations, EnviroSystems
is required to repurchase all or any part of such holder's senior discount notes
at a purchase price in cash equal to 101% of the principal amount of the senior
discount notes plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date).
 
    The indenture governing EnviroSystems senior discount notes imposes certain
affirmative covenants and other requirements on EnviroSystems and us and also
contains certain negative covenants that include, among other things,
limitations on:
 
    - the amount of indebtedness EnviroSystems and its restricted subsidiaries
      may incur;
 
    - certain payments EnviroSystems and its restricted subsidiaries may make;
 
    - restrictions on distributions from restricted subsidiaries;
 
    - sales of assets by EnviroSystems and its restricted subsidiaries;
 
    - affiliate transactions;
 
    - investments;
 
    - EnviroSystems' ability to merge or consolidate or transfer all or
      substantially all of its assets; and
 
    - certain acquisitions by EnviroSystems and its restricted subsidiaries.
 
    This indenture also contains customary events of defaults, including default
in any payment of principal and interest on any senior discount notes when due.
If an event of default occurs and is continuing, the holders of a majority in
principal amount of the outstanding senior discount notes by notice to
EnviroSystems may declare the principal and accrued and unpaid interest on all
of the then outstanding senior discount notes to be due and payable. Upon such a
declaration, such principal and accrued and unpaid interest shall be due and
payable immediately.

TERMS OF THE NOTES
 
    The Notes are unsecured senior subordinated obligations of the Company,
limited to $100 million aggregate principal amount, and mature on October 31,
2008. The Notes are subordinate in right of payment to certain other debt
obligations of the Company. The Notes bear interest at the rate per annum shown
on the cover page hereof from October 16, 1998, or from the most recent date to
which interest has been paid or provided for, payable semiannually to Holders of
record at the close of business on April 15 and October 15 immediately preceding
the interest payment date on April 30 and October 31 of each year, commencing
April 30, 1999. For U.S. federal income tax purposes, however, the "issue price"
of the Notes is less than the aggregate principal amount to the extent of the
fair market value of the Shares acquired in connection with the purchase of the
Notes. To the extent of such difference, "original issue discount" ("OID") will
be recognized by a Holder during such Holder's ownership of the Notes. See
"Certain United States Federal Income Tax Considerations" for a discussion
regarding the taxation of such OID. The Company will pay interest on overdue
principal at 1% per annum in excess of such rate, and it will pay interest on
overdue installments of interest at such higher rate to the extent lawful.
Interest on the Notes is computed on the basis of a 360-day year of twelve
30-day months.
 
OPTIONAL REDEMPTION
 
    At any time prior to October 31, 2001, the Company may redeem in the
aggregate up to 35% of the original principal amount of the Notes with the Net
Cash Proceeds of one or more Public Equity Offerings, at a redemption price of
113% of the principal amount thereof plus accrued interest to the redemption
date; PROVIDED, HOWEVER, that at least 65% of the aggregate principal amount of
the Notes originally outstanding must remain outstanding after each such
redemption.
 
    Except as set forth in the preceding paragraph, the Notes are not redeemable
at the option of the Company prior to October 31, 2003. After October 31, 2003,
the Company may redeem all or a part of the Notes upon not less than 30 nor more
than 60 days' notice, at the following redemption prices (expressed in
percentages of principal amount), plus accrued and unpaid interest to the
redemption date, if redeemed during the 12-month period commencing on October 31
of the years set forth below:

</TABLE>
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not listed on a securities exchange, by the Trustee on a pro rata
basis, by lot or by such other method as the Trustee in its sole discretion
shall deem to be fair and appropriate, although no Note of $1,000 in original
principal amount or less shall be redeemed in part. If any Note is to be
redeemed in part only, the notice of redemption relating to such Note shall
state the portion of the principal amount thereof to be redeemed. A new Note in
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Note.
 
    The Notes do not have the benefit of a sinking fund.
 
SUBSIDIARY GUARANTEES
 
    The Subsidiary Guarantors unconditionally guarantee, jointly and severally,
on a senior subordinated basis, the obligations of the Company pursuant to the
Notes, including the repurchase obligation resulting
 
                                       81
<PAGE>
from a Change of Control. The obligations of each Subsidiary Guarantor under its
Subsidiary Guarantee is limited as necessary to that Subsidiary Guaranty from
constituting a fraudulent conveyance under applicable law. See "Risk
Factors--Fraudulent Transfer Considerations".
 
    A Subsidiary Guarantor may consolidate with, merge with or into, or transfer
all or substantially all its assets to any other Person to the extent described
below under "--Certain Covenants--Merger and Consolidation"; PROVIDED, HOWEVER,
that if such other Person is not the Company or another Subsidiary Guarantor,
such Subsidiary Guarantor's obligations under its Subsidiary Guarantee must be
expressly assumed by such other Person. However, upon the sale or other
disposition (including by way of consolidation or merger) of a Subsidiary
Guarantor or the sale or disposition of all or substantially all the assets of a
Subsidiary Guarantor (in each case other than to the Company or an Affiliate of
the Company) permitted by the Indenture (including pursuant to the exercise of
remedies in respect of any Lien on the capital stock of a Subsidiary Guarantor,
which Lien secures outstanding Bank Indebtedness), such Subsidiary Guarantor
will be released and relieved from all its obligations under its Subsidiary
Guarantee.
 
SUBORDINATION
 
    The payment of principal, premium and interest, if any, on the Notes is
contractually subordinated to the prior payment in full of all Senior
Indebtedness of the Company.
 
    The obligations of a Subsidiary Guarantor under its Subsidiary Guarantee is
a senior subordinated obligation of such Subsidiary Guarantor. As such, the
rights of Holders of the Notes to receive payment by a Subsidiary Guarantor
pursuant to its Subsidiary Guarantee is contractually subordinated in right of
payment to the rights of holders of Senior Indebtedness of such Subsidiary
Guarantor. The terms of the subordination provisions described herein with
respect to the Company's obligations under the Notes apply equally to a
Subsidiary Guarantor and the obligations of such Subsidiary Guarantor under its
Subsidiary Guarantee.
 
    Indebtedness of the Company and the Subsidiary Guarantors that constitutes
Senior Indebtedness ranks senior to the Notes and the relevant Subsidiary
Guarantee in accordance with the provisions of the Indenture. The Notes and the
Subsidiary Guarantees in all respects rank PARI PASSU with all other Senior
Subordinated Indebtedness of the Company and the Subsidiary Guarantors,
respectively, and rank senior to all other Subordinated Obligations of the
Company and the Subsidiary Guarantors, respectively. See "--Subsidiary
Guarantees", "Risk Factors--Subordinated Ranking of Notes" and "Risk
Factors--Fraudulent Transfer Considerations".
 
    As of September 30, 1998, after giving pro forma effect to the acquisition
of Envirotest and the related transactions:
 
(1) the Senior Indebtedness of the Company and the Subsidiary Guarantors, to
    which the Notes and the Subsidiary Guarantees are subordinated, would have
    been approximately $438.1 million, consisting principally of approximately
    $385.0 million of Indebtedness Incurred under the Senior Secured Credit
    Facility and $53.1 million of Indebtedness Incurred under the Ohio Notes;
    and
 
(2) there would have been no Senior Subordinated Indebtedness of the Company or
    the Subsidiary Guarantors ranking PARI PASSU with the Notes or the
    Subsidiary Guarantees, or any Subordinated Obligations ranking junior to the
    Notes or the Subsidiary Guarantees.
 
    In addition, claims of creditors of the Company's Subsidiaries, including
trade creditors, secured creditors and creditors holding indebtedness and
guarantees issued by such Subsidiaries, and claims of preferred stockholders, if
any, of such Subsidiaries, generally have priority with respect to the assets
and earnings of such Subsidiaries over the claims of the creditors of the
Company, including the Holders of the Notes, even if such obligations do not
constitute Senior Indebtedness. The Notes therefore are effectively subordinated
to existing and future liabilities of Subsidiaries of the Company, except to the
extent that the Subsidiary Guarantees may be enforceable by Holders of the Notes
against the Subsidiary Guarantors.
 
                                       82
<PAGE>
    Each of the Company and the Subsidiary Guarantors will not Incur, directly
or indirectly, any Indebtedness that is subordinate or junior in ranking in
right of payment to its Senior Indebtedness unless such Indebtedness is, among
other things, Senior Subordinated Indebtedness or is expressly subordinated in
right of payment to Senior Subordinated Indebtedness. Unsecured Indebtedness is
not deemed to be subordinated or junior to Secured Indebtedness merely because
it is unsecured.
 
    The Company may not make any payment in respect of the Notes if:
 
(1) a payment default on Senior Indebtedness occurs and is continuing beyond any
    applicable grace period; or
 
(2) any other default on any Senior Indebtedness occurs and the maturity of such
    Senior Indebtedness is accelerated in accordance with its terms unless, in
    either case, the default has been cured or waived and any such acceleration
    has been rescinded or such Senior Indebtedness has been paid in full in
    cash. However, the Company may pay the Notes without regard to the foregoing
    if the Company and the Trustee receive written notice approving such payment
    from the Representative of such Senior Indebtedness.
 
    During the continuance of any default with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be accelerated either
immediately without further notice (except such notice as may be required to
effect such acceleration) or upon notice or the expiration of any applicable
grace periods, the Company may not pay the Notes for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
Representative of the holders of such Designated Senior Indebtedness specifying
an election to effect a Payment Blockage Period and ending 179 days thereafter.
Payments on the Notes may and shall be resumed if such Payment Blockage Period
is terminated:
 
(1) by written notice to the Trustee and the Company from the Person or Persons
    who gave such Blockage Notice;
 
(2) because the default giving rise to such Blockage Notice is no longer
    continuing (solely as evidenced by written notice to the Trustee by the
    Representative of such Designated Senior Indebtedness which notice shall be
    promptly delivered); or
 
(3) because such Designated Senior Indebtedness has been repaid in full in cash.
 
    Unless the holders of such Designated Senior Indebtedness or the
Representative of such holders have accelerated the maturity of such Designated
Senior Indebtedness, the Company may resume payments on the Notes after the end
of such Payment Blockage Period.
 
    No more than one Payment Blockage Period may be commenced in any consecutive
360-day period, irrespective of the number of defaults with respect to
Designated Senior Indebtedness during such period.
 
    During the continuance of, or upon any payment or distribution of the assets
of either the Company or any Subsidiary Guarantor upon, a total or partial
liquidation or dissolution or reorganization of or similar proceeding, or any
bankruptcy, insolvency, receivership or similar proceedings, relating to either
the Company or any Subsidiary Guarantor or its property or an assignment for the
benefit of creditors or marshalling of assets and liabilities of the Company or
any Subsidiary Guarantor, the holders of Senior Indebtedness will be entitled to
receive payment in full of such Senior Indebtedness before the Holders of the
Notes are entitled to receive any payment, and until the Senior Indebtedness is
paid in full in cash, any payment or distribution to which Holders of the Notes
would be entitled but for the subordination provisions of the Indenture will be
made to holders of such Senior Indebtedness as their interests may appear. If a
payment or distribution is made to Holders of the Notes that, due to the
subordination provisions, should not have been made to them, such Holders of the
Notes are required to hold it in trust for the holders of Senior Indebtedness
and pay it over to them as their interests may appear.
 
                                       83
<PAGE>
    If payment of the Notes is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of Designated Senior
Indebtedness or the Representative of such holders of the acceleration.
 
    By reason of the subordination provisions contained in the Indenture, in the
event of insolvency, creditors of the Company or a Subsidiary Guarantor who are
holders of Senior Indebtedness of the Company or such Subsidiary Guarantor, as
the case may be, may recover more, ratably, than the Holders of the Notes, and
creditors of the Company or such Subsidiary Guarantor who are not holders of
Senior Indebtedness may recover less, ratably, than holders of Senior
Indebtedness and may recover more, ratably, than the Holders of the Notes.
 
    The terms of the subordination provisions described above do apply to
payments from money or the proceeds of U.S. Government Obligations held in trust
by the Trustee for the payment of principal of and interest on the Notes
pursuant to the provisions described under "--Defeasance".
 
    No provision contained in the Indenture, the Notes or the Subsidiary
Guarantees affects the obligation of the Company and the Subsidiary Guarantors,
which is absolute and unconditional, to pay, when due, principal of, premium, if
any, and interest on the Notes. The subordination provisions of the Indenture
the Notes and the Subsidiary Guarantees does not prevent the occurrence of any
Default or Event of Default under the Indenture or limit the rights of the
Trustee or any Holder to pursue any other rights or remedies with respect to the
Notes or the Subsidiary Guarantees.
 
CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, each Holder shall have the right
to require that the Company repurchase all or, at each Holder's option, any part
of such Holder's Notes at a purchase price in cash equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of purchase. Within 20 days following any Change of Control, the Company shall
mail a notice to the Trustee and to each Holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Notes on the Change of Control payment date specified in such notice, pursuant
to the procedures required by the Indenture and described in such notice. The
Company shall comply with the requirements of Section 14(e) of the Exchange Act
and any other securities laws or regulations in connection with the repurchase
of Notes pursuant to the covenant described hereunder. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
the covenant described hereunder, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the covenant described hereunder by virtue thereof.
 
    The Change of Control repurchase feature is a result of negotiations between
the Company and the purchasers of the Notes. Management has no present intention
to engage in a transaction involving a Change of Control, although it is
possible that the Company would decide to do so in the future. Subject to the
limitations discussed below, the Company could, in the future, enter into
certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of Indebtedness outstanding at
such time or otherwise affect the Company's capital structure or credit ratings.
Restrictions on the ability of the Company to Incur additional Indebtedness are
contained in the covenant described under "--Certain Covenants--Limitation on
Indebtedness". Such restrictions can be waived only with the consent of the
Holders of a majority in principal amount of the Notes then outstanding. Except
for the limitations contained in such covenant, however, the Indenture does not
contain any covenants or provisions that may afford Holders protection in the
event of a highly leveraged transaction.
 
    If a Change of Control offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the purchase price for all
of the Notes that might be delivered by Holders seeking to accept the Change of
Control offer. The failure of the Company to make or consummate the Change of
 
                                       84
<PAGE>
Control offer or pay the purchase price when due will give the Trustee and the
Holders the rights described under "--Events of Default".
 
    The existence of a Holder's right to require the Company to offer to
repurchase such Holder's Notes upon a Change of Control may deter a third party
from acquiring the Company in a transaction which constitutes a Change of
Control.
 
    The Senior Secured Credit Facility prohibits the Company from purchasing any
Notes prior to its expiration, and also provides that the occurrence of certain
change of control events with respect to the Company would constitute a default
thereunder. In the event a Change of Control occurs at a time when the Company
is prohibited by the terms of any Indebtedness from purchasing Notes, the
Company may seek the consent of its lenders thereunder to the purchase of Notes
or may attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company
will remain contractually prohibited from purchasing Notes. In such case, the
Company's failure to purchase tendered Notes would constitute an Event of
Default under the Indenture which would, in turn, constitute a default under the
Senior Secured Credit Facility. In such circumstances, the subordination
provisions in the Indenture would likely restrict payment to the Holders of
Notes.
 
    Future Indebtedness of the Company may contain prohibitions on the
occurrence of certain events that would constitute a Change of Control or
require such Indebtedness to be repaid or repurchased upon a Change of Control.
Moreover, the exercise by the Holders of their right to require the Company to
repurchase the Notes could cause a default under such Indebtedness, even if the
Change of Control itself does not, due to the financial effect of such
repurchase on the Company. Finally, the Company's ability to pay cash to the
Holders following the occurrence of a Change of Control may be limited by the
Company's then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases of Notes. The provisions under the Indenture relating to the
Company's obligation to make an offer to repurchase the Notes as a result of a
Change of Control may be waived or modified with the written consent of each
Holder of Notes at the time outstanding.
 
CERTAIN COVENANTS
 
    The Indenture contains covenants including, among others, the following:
 
    LIMITATION ON INDEBTEDNESS.
 
    (a) The Company shall not, and shall not permit any Restricted Subsidiary
to, Incur, directly or indirectly, any Indebtedness (including Acquired
Indebtedness); PROVIDED, HOWEVER, that the Company or any Subsidiary Guarantor
shall be permitted to Incur such Indebtedness if, on the date of such
Incurrence, and after giving pro forma effect thereto, no Default or Event of
Default shall have occurred and be continuing or would occur and the
Consolidated Cash Flow Coverage Ratio at the date of such Incurrence exceeds
2.10 to 1.0 if such Indebtedness is Incurred prior to October 31, 1999, and 2.35
to 1 if such Indebtedness is Incurred thereafter.
 
    (b) So long as no Default shall have occurred and be continuing or would be
caused thereby, paragraph (a) of this covenant will not prohibit the incurrence
of any of the following items of Indebtedness:
 
(1) Indebtedness Incurred pursuant to the Senior Secured Credit Facility not to
    exceed $435 million in aggregate principal amount outstanding at any time,
    less the aggregate amount of all mandatory payments applied to permanently
    reduce the commitments with respect to such Indebtedness, including but not
    limited to reductions pursuant to the first paragraph of the covenant
    described under the caption "--Limitation on Sale of Assets and Subsidiary
    Stock";
 
                                       85
<PAGE>

    such Indebtedness is subordinated in right of payment to the Notes;
    PROVIDED, FURTHER, that any subsequent issuance, sale, transfer or other
    disposition of any Capital Stock (including by consolidation or merger) or
    other event (including the designation of a Restricted Subsidiary as an
    Unrestricted Subsidiary under the covenant described under the caption
    "--Limitation on Designations of Unrestricted Subsidiaries") which results
    in such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
    subsequent transfer or other disposition of any such Indebtedness (except to
    the Company or another Restricted Subsidiary) shall be deemed, in each case,
    to be an Incurrence of such Indebtedness by the issuer thereof at the time
    of any such issuance, sale, transfer or other disposition, as the case may
    be;
 
(3) Indebtedness of a Restricted Subsidiary to the Company or another Restricted
    Subsidiary; PROVIDED that (x) if a Subsidiary Guarantor Incurs such
    Indebtedness to a Restricted Subsidiary that is not a Subsidiary Guarantor,

    Guarantee of such Subsidiary Guarantor; and (y) if a Restricted Subsidiary
    that is not a Subsidiary Guarantor Incurs such Indebtedness to the Company
    or a Restricted Subsidiary that is a Subsidiary Guarantor, the Incurrence of
    such Indebtedness constitutes a Restricted Investment for the purposes of
    the covenant described under the caption "--Limitation on Restricted
    Payments"; PROVIDED, FURTHER, that any subsequent issuance, sale, transfer
    or other disposition of any Capital Stock (including by consolidation or
    merger) of any Restricted Subsidiary to which such Indebtedness is owed or
    any other event (including the designation of a Restricted Subsidiary as an
    Unrestricted Subsidiary under the covenant described under the caption
    "--Limitation on Designations of Unrestricted Subsidiaries") which results
    in such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
    subsequent transfer or other disposition of any such Indebtedness (except to
    the Company or another Restricted Subsidiary that is a Subsidiary Guarantor)
    shall be deemed, in each case, to be an Incurrence of such Indebtedness by
    the issuer thereof at the time of any such issuance, sale, transfer or other
    disposition, as the case may be;
 
(4) the Notes and the Subsidiary Guarantees;
 
(5) Indebtedness (other than Indebtedness described in clause (1), (2), (3) or
    (4) above) outstanding on the Issue Date;
 
(6) any Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to

(7) obligations of the Company or any Restricted Subsidiary pursuant to (A)
    Interest Rate Protection Agreements designed to protect the Company or such
    Restricted Subsidiary against fluctuations in interest rates in respect of
    Indebtedness of the Company or such Restricted Subsidiary that is permitted
    by the terms of the Indenture to be outstanding to the extent the notional
    principal amount of such obligation does not exceed the aggregate principal
    amount of the Indebtedness to which such Interest Rate Protection Agreements
    relate, (B) Currency Agreement Obligations in respect of foreign exchange
    exposures Incurred by the Company or any Restricted Subsidiary in the
    ordinary course of its business and (C) commodity agreements of the Company
    or any Restricted Subsidiary to the extent entered into in the ordinary
    course of business to protect the Company or such Restricted Subsidiary from
    fluctuations in the prices of raw materials used in its business;
 
                                       86

    acquisition or disposition of assets by the Company or such Restricted
    Subsidiary permitted under the Indenture;
 
(9) Capital Lease Obligations, Purchase Money Indebtedness and Acquired
    Indebtedness (to the extent not Incurred in connection with, or in
    anticipation or contemplation of, the relevant transaction), in each case
    Incurred in connection with a Related Business, and any Refinancing
    Indebtedness in respect thereof in an aggregate principal amount not
    exceeding $10.0 million at any time outstanding;
 
(10) Attributable Debt in connection with Sale/Leaseback Transactions in an
    aggregate principal amount not exceeding $10.0 million at any time

    any one time outstanding;
 
(12) Indebtedness in an amount not to exceed $4.5 million issued in connection
    with the Investment permitted pursuant to clause (12) of the definition of

    other Indebtedness of the Company and its Restricted Subsidiaries then
    outstanding (other than Indebtedness Incurred pursuant to clauses (1)
    through (12) of this Section or paragraph (a)), does not exceed $10.0
    million.
 
    (c) Notwithstanding that such Indebtedness is permitted to be incurred
pursuant to paragraphs (a) and (b) above, the Company shall not, and shall not
permit any Restricted Subsidiary to, Incur any Indebtedness if the proceeds
thereof are used, directly or indirectly, to repay, prepay, redeem, defease,
retire, refund or refinance any Subordinated Obligations unless such
Indebtedness shall be subordinated to the Notes or the relevant Subsidiary
Guarantee, as applicable, to at least the same extent as such Subordinated
Obligations.
 
    (d) For purposes of determining compliance with the covenant entitled
"--Limitation on Indebtedness" in the event that an item of Indebtedness meets
the criteria of more than one of the types of Indebtedness described in
paragraphs (a) or (b) above, the Company, in its sole discretion at the time of
the Incurrence of such Indebtedness, will classify such item of Indebtedness,
and, except as specifically stated otherwise, will only be required to include
the amount of such Indebtedness, in one of the above clauses, and such item of
Indebtedness may be divided and classified among more than one of such types.
 
    (e) For purposes of determining amounts of Indebtedness outstanding under
the covenant entitled "--Limitation on Indebtedness" and for the purpose of
avoiding duplication only, Indebtedness resulting from security interests
granted with respect to Indebtedness otherwise included in the determination of
Indebtedness, and Guarantees (and security interests with respect thereof) of,
or obligations with respect to letters of credit supporting, Indebtedness
otherwise included in the determination of Indebtedness shall not be included in

    (f) Indebtedness of any Person which is outstanding at the time such Person
becomes a Restricted Subsidiary of the Company (including upon designation of
any subsidiary or other person as a Restricted Subsidiary) or is merged with or
into or consolidated with the Company or a Restricted Subsidiary of the Company
shall be deemed to have been Incurred at the time such Person becomes a
Restricted Subsidiary of the Company or merged with or into or consolidated with
the Company or a Restricted Subsidiary of the Company, as applicable.
 
    LIMITATION ON LIENS SECURING SUBORDINATED INDEBTEDNESS.  The Company will
not, and will not permit any Restricted Subsidiary to, directly or indirectly,
create, Incur, assume or suffer to exist any Liens of any kind (other than
Permitted Liens) upon any of their respective assets or properties now owned or
acquired after the date of the Indenture or any income or profits therefrom
securing:
 
                                       87
<PAGE>
(1) any Indebtedness of the Company or a Restricted Subsidiary which is
    expressly by its terms subordinate or junior in right of payment to any
    other Indebtedness of the Company or such Restricted Subsidiary, as the case
    may be, unless the Notes or the relevant Subsidiary Guarantee, as the case
    may be, are equally and ratably secured for so long as such Indebtedness is
    so secured; PROVIDED that, if such Indebtedness which is expressly by its
    terms subordinate or junior in right of payment to any other Indebtedness of
    the Company or a Restricted Subsidiary is expressly subordinate or junior to
    the Notes or the relevant Subsidiary Guarantee, as the case may be, then the
    Lien securing such subordinated or junior Indebtedness shall be subordinate
    and junior to the Lien securing the Notes or the relevant Subsidiary
    Guarantee, as the case may be, with the same relative priority as such
    subordinated or junior Indebtedness shall have with respect to the Notes or
    the relevant Subsidiary Guarantee, as the case may be; or
 
(2) any assumption, Guarantee or other liability of the Company or such
    Restricted Subsidiary in respect of any Indebtedness of the Company or a
    Restricted Subsidiary which is expressly by its terms subordinate or junior
    in right of payment to any other Indebtedness of the Company or such
    Restricted Subsidiary, unless the Notes or the relevant Subsidiary
    Guarantee, as the case may be, are equally and ratably secured for so long
    as such assumption, guaranty or other liability is so secured; PROVIDED
    that, if such subordinated Indebtedness which is expressly by its terms
    subordinate or junior in right of payment to any other Indebtedness of the
    Company or a Restricted Subsidiary is expressly by its terms subordinate or
    junior to the Notes or the relevant Subsidiary Guarantee, as the case may
    be, then the Lien securing the assumption, Guarantee or other liability of
    such Subsidiary shall be subordinate and junior to the Lien securing the
    Notes or the relevant Subsidiary Guarantee, as the case may be, with the
    same relative priority as such subordinated or junior Indebtedness shall
    have with respect to the Notes or the relevant Subsidiary Guarantee, as the
    case may be.
 
    LIMITATION ON OTHER SENIOR SUBORDINATED INDEBTEDNESS.  The Company will not,
and will not permit any Restricted Subsidiary to, create, Incur, assume,
guarantee or in any other manner become liable with respect to any Indebtedness
that is subordinate in right of payment to any other Indebtedness of the Company
or any such Restricted Subsidiary, unless such Indebtedness is also PARI PASSU
with, or subordinate in right of payment to, the Notes, or the relevant
Subsidiary Guarantee, as the case may be.
 
    LIMITATION ON RESTRICTED PAYMENTS.
 
    (a) The Company shall not, and shall not permit any Restricted Subsidiary
       to, directly or indirectly:
 
    (A) declare or pay any dividend or make any distribution on or in respect
       of, or to the direct or indirect holders of, the Capital Stock of
       EnviroSystems, the Company, any Restricted Subsidiary or any other
       Affiliate of the Company in their capacities as such except dividends or
       distributions payable solely in its respective Capital Stock (other than
       Disqualified Stock or, except in the case of the Company, Preferred
       Stock) or in options, warrants or other rights to purchase its respective
       Capital Stock (other than Disqualified Stock or, except in the case of
       the Company, Preferred Stock) and except dividends or distributions
       payable to the Company or a Restricted Subsidiary;
 
    (B) purchase, redeem or otherwise acquire or retire for value any Capital
       Stock of EnviroSystems, the Company, any Restricted Subsidiary or any
       other Affiliate of the Company to the extent such Capital Stock is held
       by Persons other than the Company or any Wholly Owned Subsidiary that is
       a Subsidiary Guarantor,
 
    (C) purchase, repurchase, redeem, defease or otherwise acquire or retire for
       value, prior to scheduled maturity, scheduled repayment or scheduled
       sinking fund payment, any Subordinated Obligations or;
 
                                       88
<PAGE>
    (D) make any Restricted Investment (any such dividend, distribution,
       purchase, redemption, repurchase, defeasance, other acquisition,
       retirement or Investment being herein referred to as a "Restricted
       Payment").
 
        if at the time the Company or such Restricted Subsidiary makes such
    Restricted Payment:
 
(1) a Default shall have occurred and be continuing (or would result therefrom);
    or
 
(2) the Company would not be permitted to Incur an additional $1.00 of
    Indebtedness pursuant to clause (a) of the covenant described under the
    caption "--Limitation on Indebtedness" after giving pro forma effect to such
    Restricted Payment; or
 
(3) the aggregate amount of such Restricted Payment (other than Restricted
    Payments made on or about the Issue Date in connection with the acquisition
    by the Company of Envirotest Systems Corp. and the transactions related
    thereto) and all other Restricted Payments since the beginning of the fiscal
    quarter during which the Notes were originally issued would exceed the sum
    of:
 
    (A) 50% of the Consolidated Net Income accrued during the period (treated as
       one accounting period) from the beginning of the fiscal quarter during
       which the Notes were originally issued to the end of the most recent
       fiscal quarter for which financial statements are available (or, in case
       such Consolidated Net Income shall be a deficit, minus 100% of such
       deficit); and
 
    (B) the aggregate Net Cash Proceeds received by the Company from the issue
       or sale of its Capital Stock (other than Disqualified Stock) or from
       Capital Contributions subsequent to the Issue Date (other than an
       issuance or sale (q) to a Restricted Subsidiary, an employee stock
       ownership plan or similar trust for the benefit of employees or (r) with
       respect to which the purchase price thereof is financed directly or
       indirectly using funds (x) borrowed from the Company or a Restricted
       Subsidiary unless and until such borrowing is repaid in full or (y)
       contributed, extended, Guaranteed or advanced by the Company or a
       Restricted Subsidiary) to the extent such proceeds or Capital
       Contributions are not used to redeem, repurchase, retire, defease or
       otherwise acquire Capital Stock or any Indebtedness of the Company or
       such Restricted Subsidiary.
 
    (b) The provisions of clauses (2) and (3) of paragraph (a) of this covenant
shall not prohibit the following Restricted Payments:
 
(1) any purchase or redemption of Capital Stock of the Company or any Restricted
    Subsidiary or Subordinated Obligations of the Company or any Subsidiary
    Guarantor made by exchange for, or out of the proceeds of the substantially
    concurrent sale or issuance of, Capital Stock of the Company (other than
    Disqualified Stock and other than Capital Stock issued or sold to a
    Subsidiary or an employee stock ownership plan or similar trust for the
    benefit of employees); PROVIDED, HOWEVER, that the Net Cash Proceeds from
    such sale and such purchases shall be excluded from the calculation in
    clause (3) of paragraph (a) of this covenant;
 
(2) dividends paid within 60 days after the date of declaration if at such date
    of declaration such dividend would have complied with the provisions of the
    Indenture; PROVIDED, HOWEVER, that, such dividend shall be deducted in the

    LIMITATION ON RESTRICTIONS ON DISTRIBUTIONS FROM RESTRICTED
SUBSIDIARIES.  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted

    governing the Senior Discount Notes, in each case as in effect on the Issue

    refinancings thereof; PROVIDED, HOWEVER, that any such amendments,
    restatements, renewals, replacements or refinancings to or under the Senior
    Secured Credit Facility or the indenture governing the Senior Discount Notes
    are not materially more restrictive, when taken as a whole, with respect to
    such dividend and other payment restrictions, to the Company or any
    Restricted Subsidiary than those contained in the Senior Secured Credit
    Facility or such indenture, as the case may be, (or,
 
                                       90
<PAGE>
    if more restrictive, than those contained in the Indenture) immediately
    prior to any such amendment, restatement, renewal, replacement or
    refinancing;
 
(2) the indenture relating to any Public Debt issued after the date hereof,
    which encumbrances or restrictions are not materially more restrictive, when
    taken as a whole, with respect to such dividend and other payment
    restrictions, to the Company or any Restricted Subsidiary than those
    contained in the Indenture;
 
(3) applicable law;
 
(4) any instrument governing Indebtedness or Capital Stock of an Acquired Person
    acquired by the Company or any of its Restricted Subsidiaries as in effect
    at the time of such acquisition (except to the extent such Indebtedness was
    incurred in connection with or in contemplation of such acquisition or in
    violation of the covenants described above under the caption "--Limitation
    on Indebtedness"); PROVIDED, HOWEVER, that (A) such restriction is not
    applicable to any Person, or the properties or assets of any Person, other
    than the Acquired Person, and (B) the consolidated net income of such

    prior to such refinancing;
 
(9) customary provisions restricting subletting or assignment of any lease
    entered into in the ordinary course of business; or

    LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK.
 
    (a) The Company shall not, and shall not permit any Restricted Subsidiary
to, make any Asset Disposition unless:
 
(1) (x) the Company or such Restricted Subsidiary receives consideration at the
    time of such Asset Disposition at least equal to the fair market value, as
    determined in good faith by the Board of Directors (including as to the
    value of all non-cash consideration), of the shares and assets subject to
    such Asset Disposition and (y) at least 80% of the consideration thereof
    received by the Company or such Restricted Subsidiary, as the case may be,
    is in the form of cash or Cash Equivalents, PROVIDED, HOWEVER, that the
    requirement set forth in (x) above shall not apply to any Asset Disposition
    to any governmental authority as may be required, from time to time, by such
    governmental authority; and
 
(2) an amount equal to 100% of the Net Available Cash from such Asset
    Disposition is applied by the Company (or such Restricted Subsidiary, as the
    case may be):
 
    (A) first, to the extent the Company elects (or is required by the terms of
       any Senior Indebtedness), to prepay, repay or purchase Senior
       Indebtedness of the Company or any Subsidiary Guarantor or any
       Indebtedness or other Obligations under the Senior Secured Credit
       Facility or, if the Asset Disposition was made by a Restricted Subsidiary
       that is not a Subsidiary Guarantor, of any Restricted Subsidiary within
       360 days of the Company's or such Restricted Subsidiary's receipt of Net
       Available Cash from such Asset Disposition;
 
    (B) second, to the extent of the balance of such Net Available Cash after
       application in accordance with clause (A), at the Company's election, to
       the investment by the Company or any Subsidiary Guarantor or, if the
       Asset Disposition was made by a Restricted Subsidiary that is not a
       Subsidiary Guarantor, any Restricted Subsidiary, in (1) assets of the
       Company, such Subsidiary Guarantor or, if the Asset Disposition was made
       by a Restricted Subsidiary that is not a Subsidiary Guarantor, such
       Restricted Subsidiary (other than Indebtedness or Capital Stock) to
       replace the assets that were the subject of such Asset Disposition or (2)
       assets (other than inventory or other current assets or Indebtedness or
       Capital Stock) of the Company, any Subsidiary Guarantor or, if the Asset
       Disposition was made by a Restricted Subsidiary that is not a Subsidiary
       Guarantor, any Restricted Subsidiary that (as determined in good faith by
       the Board of Directors) are related to the business of the Company and
       the Wholly Owned Subsidiaries existing on the Issue Date or which are
       used in a Related Business, in each case within 360 days from the date of
       the Company's or such Restricted Subsidiary's receipt of Net Available
       Cash from such Asset Disposition;
 
    (C) third, to the extent of the balance of such Net Available Cash after
       application in accordance with clauses (A) and (B), to make a PRO RATA
       offer to purchase Notes at par (and, to the extent required by the
       instrument governing such Indebtedness, any other Senior Subordinated
       Indebtedness designated by the Company, at a price no greater than par or
       accreted value, whichever is less) plus accrued and unpaid interest; and
 
    (D) fourth, to the extent of the balance of such Net Available Cash after
       application in accordance with clauses (A), (B) and (C), in any manner
       that does not violate the Indenture; PROVIDED, HOWEVER, that in
       connection with any prepayment, repayment or purchase of Indebtedness
       pursuant to clause (A) or (C) above, the Company or such Subsidiary shall
       permanently retire such Indebtedness and cause the related loan
       commitment, if any, to be permanently reduced in an amount equal to the
       principal amount so prepaid, repaid or purchased.
 
    Notwithstanding the foregoing provisions of this clause (a), the Company and
its Restricted Subsidiaries shall not be required to apply any Net Available
Cash in accordance with clause (a)(2)(C) above except to the extent that the
aggregate Net Available Cash from all Asset Dispositions which are not applied
in
 
                                       92
<PAGE>
accordance with clauses (a)(2)(A) and (B) above exceeds $10.0 million. Pending
application of Net Available Cash pursuant to this clause (a), such Net
Available Cash shall be used to temporarily reduce Senior Indebtedness or
invested in Cash Equivalents.
 
    For the purposes of this covenant, the following is deemed to be cash or
Cash Equivalents: the express assumption of Indebtedness (other than any
Indebtedness that is by its terms subordinated to the Notes) of the Company or
any Restricted Subsidiary, but only to the extent that such assumption is
effected on a basis under which there is no further recourse to the Company or
any of the Restricted Subsidiaries with respect to such liabilities.
 
    (b) In the event of an Asset Disposition that requires the purchase of the
Notes (and other Senior Subordinated Indebtedness) pursuant to clause (a)(2)(C)
above, the Company will be required to purchase Notes tendered pursuant to an
offer by the Company for the Notes (and, to the extent required, other Senior
Subordinated Indebtedness) at a purchase price of 100% of their principal amount
or the accreted value thereof, whichever is less, (without premium) plus accrued
but unpaid interest (or, in respect of such other Senior Subordinated
Indebtedness such lesser price, if any, as may be provided for by the terms of
such other Senior Subordinated Indebtedness) in accordance with the procedures
(including prorating in the event of oversubscription) set forth in the
Indenture which shall include, among other things, that the offer shall remain
open for 20 Business Days following commencement. If the aggregate purchase
price of Notes (and, to the extent required, any other Senior Subordinated
Indebtedness) tendered pursuant to such offer is less than the Net Available
Cash allotted to the purchase thereof, the Company will be required to apply the
remaining Net Available Cash in accordance with clause (a)(2)(D) above.
 
    (c) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.
 
    (d) The Senior Secured Credit Facility requires the Company to repay all of
its obligations under the Senior Secured Credit Facility prior to repurchasing
Notes as a result of an Asset Disposition. In order to repurchase Notes pursuant
to clauses (a) and (b) above prior to repaying its obligations under the Senior
Secured Credit Facility, the Company would have to obtain the consent of the
lenders under the Senior Secured Credit Facility. If the Company does not obtain
such a consent or repay its obligations under the Senior Secured Credit
Facility, the Company will be contractually prohibited from repurchasing the
Notes. In such case, the Company's failure to repurchase the Notes would
constitute an Event of Default under the Indenture which would, in turn,
constitute a default under the Senior Secured Credit Facility.
 
    LIMITATION ON AFFILIATE TRANSACTIONS.
 
    The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, conduct any business or enter into any transaction or
series of similar transactions (including the purchase, sale, lease, transfer or
other disposition or exchange of any asset or property or the rendering of any
service) with any Affiliate of the Company (other than the Company or any Wholly
Owned Subsidiary of the Company or any employee stock ownership plan or similar
trust for the benefit of the Company's or a Restricted Subsidiary's employees)
unless:
 
(1) the terms of such business, transaction or series of transactions are no
    less favorable to the Company or such Restricted Subsidiary as terms that
    would be obtainable at the time for a comparable transaction or series of
    similar transactions in arms' length dealings with an unrelated third
    Person; and
 
                                       93
<PAGE>
(2) the Company delivers to the Trustee:
 
    (A) with respect to any transaction involving an aggregate amount in excess
       of $5.0 million, a resolution of the Board of Directors certifying that a
       majority of the disinterested members of such Board have determined in
       good faith that such business or transaction or series of transactions
       meets the criteria set forth in (1) above and have approved the
       transaction; and
 
    (B) with respect to any transaction involving an amount in excess of $10.0
       million, the Board resolution set forth in (2)(A) above, as well as an
       opinion as to the fairness from a financial point of view to the Company
       or its Restricted Subsidiary, as the case may be, issued by a nationally
       recognized independent investment banking firm, accounting firm or
       appraisal firm with experience in evaluating the terms and conditions of
       the type of business or transaction.
 
    The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

    described under the caption "--Limitation on Restricted Payments", or any
    payment or transaction specifically excepted from the definition of
    Restricted Payment;

    of Directors or by a majority of the disinterested members of the Board of
    Directors or a majority of the entire board of directors or by a majority of
    the disinterested members of the board of directors of the relevant
    Restricted Subsidiary;
 
(3) the grant of stock options or similar rights to employees and directors
    pursuant to plans approved by a majority of the entire Board of Directors or
    by a majority of the disinterested members of the Board of Directors or a
    majority of the entire board of directors or by a majority of the
    disinterested members of the board of directors of the relevant Restricted
    Subsidiary;
 
(4) loans or advances to officers, directors or employees in the ordinary course
    of business which, except with respect to ordinary travel expenses and
    advances, have been approved by the Board of Directors;
 
(5) the payment of reasonable fees to directors of EnviroSystems, the Company
    and the Subsidiaries who are not employees of EnviroSystems, the Company or
    the Subsidiaries for rendering of services (including attending meetings of
    the board of directors) as a director;
 
(6) any Affiliate transaction between the Company and a Subsidiary Guarantor,
    between Subsidiary Guarantors, or between Restricted Subsidiaries which are
    each not Subsidiary Guarantors;
 
(7) indemnification or insurance provided to officers or directors of
    EnviroSystems, the Company or any Subsidiary of the Company approved in good

    the equivalent thereof in another currency) plus reasonable out of pocket
    expenses;
 
(10) loans made to officers of the Company or its Subsidiaries in an aggregate
    amount not to exceed $4.5 million outstanding at any time solely for the
    purpose of reimbursing such officers for the amount of income taxes payable
    by such officers in connection with shares of Capital Stock of EnviroSystems
 
                                       94

    issued to such officers, which shares are pledged to the Company or the
    Subsidiary making such loans; and
 
(11) the Permitted Investment contemplated by clause (12) of the definition of
    "Permitted Investment".
 
    MERGER AND CONSOLIDATION.  The Company shall not, in a single transaction or
a series of related transactions, consolidate with or merge with or into, or
sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all its assets (computed on a consolidated basis) to, any Person
or group of affiliated Persons, unless:
 
(1) the resulting, surviving or transferee Person shall be the Company or, if
    not the Company, shall be a corporation organized and existing under the
    laws of the United States of America, any State thereof or the District of
    Columbia (the "Successor Company"), and such Successor Company shall
    expressly assume, by an indenture supplemental to the Indenture in form
    reasonably satisfactory to the Trustee, executed and delivered to the
    Trustee, all the obligations of the Company under the Notes and the
    Indenture (and the Subsidiary Guarantees shall be confirmed as applying to
    such Person's obligations);
 
(2) at the time of and immediately after giving effect to such transaction or
    transactions on a pro forma basis (and treating any Indebtedness which
    becomes an obligation of the resulting, surviving or transferee Person or
    any Subsidiary as a result of such transaction as having been Incurred by
    such Person or such Subsidiary at the time of such transaction), no Default
    or Event of Default shall have occurred and be continuing;
 
(3) immediately after giving effect to such transaction, (and treating any
    Indebtedness which becomes an obligation of the resulting, surviving or
    transferee Person or any Subsidiary as a result of such transaction as
    having been Incurred by such Person or such Subsidiary at the time of such
    transaction) the resulting, surviving or transferee Person would be able to
    Incur at least $1.00 of Indebtedness pursuant to the first paragraph of the
    covenant described under the caption "--Limitation on Indebtedness"; and
 
(4) the Company shall have delivered to the Trustee an Officers' Certificate and
    if a supplemental indenture is required, an Opinion of Counsel, each stating
    that such consolidation, merger or transfer and such supplemental indenture
    (if any) comply with the Indenture.
 
    The Successor Company shall be the successor to the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture, and the predecessor company, in the case of a
sale, assignment conveyance, transfer or other disposition (but not in the case
of a lease), shall be released from the obligation to pay the principal of and
interest on the Notes.
 
    Notwithstanding the foregoing, the consolidation or merger of the Company
with, or the sale, assignment, conveyance, transfer, lease or other disposition
by the Company of all or substantially all of its property or assets to, one or
more Subsidiaries of the Company shall not relieve the Company from its
obligations under the Notes and the Indenture.
 
    For purposes of the foregoing, the transfer (by sale, assignment,
conveyance, transfer, lease or otherwise) of all or substantially all of the
properties and assets of one or more Subsidiaries, the Company's interest in
which constitutes all or substantially all of the properties and assets of the
Company, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.
 
    The Company will not permit any Subsidiary Guarantor to consolidate with or
merge with or into, or sell, assign, convey, transfer, lease or otherwise
dispose of, in one transaction or a series of transactions, all or substantially
all of its assets to, any Person unless:
 
(1) the resulting, surviving or transferee Person shall be the Company or a
    Subsidiary Guarantor or, if not the Company or such a Subsidiary Guarantor,
    shall be a corporation organized and existing under the
 
                                       95
<PAGE>
    laws of the jurisdiction under which such Subsidiary was organized or under
    the laws of the United States of America, or any State thereof or the
    District of Columbia, and such Person shall expressly assume, by executing a
    Subsidiary Guarantee, all the obligations of such Subsidiary, if any, under
    its Subsidiary Guarantee;
 
(2) immediately after giving effect to such transaction or transactions on a pro
    forma basis (and treating any Indebtedness which becomes an obligation of
    the resulting, surviving or transferee Person as a result of such
    transaction as having been issued by such Person at the time of such
    transaction), no Default or Event of Default shall have occurred and be
    continuing;
 
(3) immediately after giving effect to such transaction, the Company would be
    able to Incur at least $1.00 of Indebtedness pursuant to the first paragraph
    of the covenant described under the caption "--Limitation on Indebtedness";
    and (iv) the Company delivers to the Trustee an Officers' Certificate and an
    Opinion of Counsel, each stating that such consolidation, merger or transfer
    and such Subsidiary Guarantee, if any, complies with the Indenture. The
    provisions of clauses (1), (2) and (3) above shall not apply to any one or
    more transactions which constitute an (a) Asset Disposition if the Company
    has complied with the applicable provisions of the covenant described under
    the caption "--Limitation on Sales of Assets and Subsidiary Stock" above or
    (b) the grant of any Lien on the assets of a Restricted Subsidiary to secure
    outstanding Indebtedness under the Senior Secured Credit Facility, which
    Lien is permitted by the terms of the Indenture, or any conveyance or
    transfer of such assets resulting from an exercise of remedies in respect of
    any such Lien.
 
    Notwithstanding the foregoing but subject to the terms of the first and
fifth paragraphs of this "Merger and Consolidation" section, as applicable, the
Company may merge with or into, or sell, assign, convey, transfer, lease or
otherwise dispose of all or substantially all of its assets to, any Subsidiary
Guarantor, and a Subsidiary Guarantor may merge with or into, or convey,
transfer or lease all or substantially all of its assets to, any other
Subsidiary Guarantor.
 
    The phrase "all or substantially all" of the assets of the Company or a
Subsidiary Guarantor will likely be interpreted under applicable state law and
will be dependent upon particular facts and circumstances. As a result, there
may be a degree of uncertainty in ascertaining whether a sale or transfer of
"all or substantially all" of the assets of the Company or a Subsidiary
Guarantor has occurred.
 
    FUTURE SUBSIDIARY GUARANTORS.  If the Company or any of the Subsidiary
Guarantors (other than SPCs) acquires or creates another Restricted Subsidiary
after the date of the Indenture:
 
(1) that is organized or existing under the laws of the United States, any state
    thereof or the District of Columbia;
 
(2) more than 65% of the Capital Stock of which is pledged to a United States
    lender; or
 
(3) that Guarantees any Indebtedness owed to a United States lender, on and
    after the date of the Indenture (if not then a Subsidiary Guarantor),
 
   then that newly acquired or created Restricted Subsidiary must execute and
    deliver an indenture supplemental to the Indenture and thereby become a
    Subsidiary Guarantor which shall be bound by the Subsidiary Guarantee of the
    Notes in the form set forth in the Indenture (without such future Subsidiary
    Guarantor being required to execute and deliver the Subsidiary Guarantee
    endorsed on the Notes).
 
    In addition, the Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor to either:
 
(1) Guarantee any other Indebtedness of the Company or any Subsidiary Guarantor;
    or
 
(2) otherwise become obligated with respect to Indebtedness of the Company or
    any Subsidiary Guarantor, including but not limited to, Indebtedness
    Incurred by the Company or a Subsidiary Guarantor
 
                                       96
<PAGE>
    under the Senior Secured Credit Facility, unless such Restricted Subsidiary
    simultaneously executes a supplemental indenture to the Indenture providing
    for the Guarantee of the payment of the Notes by such Restricted Subsidiary,
    which Guarantee of the payment of the Notes shall be subordinated to the
    Guarantee of such other Indebtedness to the same extent as the Notes or the
    Subsidiary Guarantees, as applicable, are subordinated to such other
    Indebtedness; PROVIDED, HOWEVER, that such Restricted Subsidiary shall not
    be required to so Guarantee the payment of the Notes to the extent that such
    other Indebtedness does not exceed $1 million individually or, together with
    any other Indebtedness of the Company or any Subsidiary Guarantor Guaranteed
    by such Restricted Subsidiary, $3 million in the aggregate. Such Restricted
    Subsidiary shall be deemed released from its obligations under the Guarantee
    of the payment of the Notes at any such time that such Restricted Subsidiary
    is released from all of its obligations under its Guarantee of such other
    Indebtedness unless such release results from the payment under such
    Guarantee of other Indebtedness.
 
    LIMITATION ON ENVIROSYSTEMS AND THE HOLDING COMPANIES.  EnviroSystems and
the Holding Companies shall not, and the Company shall not permit the Holding
Companies to, engage in any business other than holding the securities of their
respective direct subsidiaries.
 
    LIMITATION ON LINES OF BUSINESS.  Neither the Company nor any of its
Subsidiaries shall directly or indirectly engage to any substantial extent in
any line or lines of business activity other than that which, in the reasonable
good faith judgment of the Board of Directors, is a Related Business.
 
    LIMITATION ON DESIGNATIONS OF UNRESTRICTED SUBSIDIARIES.  The Company may
designate any Subsidiary of the Company (other than a Subsidiary Guarantor) as
an "Unrestricted Subsidiary" under the Indenture (a "Designation") only if:
 
(1) no Default shall have occurred and be continuing at the time of or after
    giving effect to such Designation; and
 
(2) either (x) the assets of such Subsidiary do not exceed $1,000 or (y) the
    Company would be permitted under the Indenture to make an Investment at the
    time of Designation (assuming the effectiveness of such Designation) in an
    amount (the "Designation Amount") equal to the fair market value of the
    Company's Investment in such Subsidiary on such date.
 
    In the event of any such Designation, the Company shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
described under the caption "--Limitation on Restricted Payments" for all
purposes of the Indenture in the Designation Amount. The Company shall not, and
shall not permit any Restricted Subsidiary to, at any time (a) provide credit
support for, or a guarantee of, any Indebtedness of any Unrestricted Subsidiary
(including any undertaking, agreement or instrument evidencing such
Indebtedness) or (b) be directly or indirectly liable for any Indebtedness of
any Unrestricted Subsidiary.
 
    The Company may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:
 
(1) no Default shall have occurred and be continuing at the time of and after
    giving effect to such Revocation; and
 
(2) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding
    immediately following such Revocation would, if Incurred at such time, have
    been permitted to be Incurred for all purposes of the Indenture and for all
    purposes of the Indenture shall be deemed to have been Incurred at such
    time.
 
    All Designations and Revocations must be evidenced by resolutions of the
Board of Directors delivered to the Trustee certifying compliance with the
foregoing provisions.
 
    Notwithstanding the foregoing, no Subsidiary that is a Subsidiary Guarantor
as of the Issue Date shall be permitted to become an Unrestricted Subsidiary.

    SEC REPORTS.  Whether or not required by the rules and regulations of the
SEC, so long as any Notes are outstanding beginning with the year ended December
31, 1998, the Company will furnish to the Trustee and all Holders of Notes:
 
(1) all quarterly and annual financial information that would be required to be
    contained in a filing with the SEC on Forms 10-Q and 10-K, as applicable, if
    the Company were required to file such Forms, including a "Management's
    Discussion and Analysis of Financial Condition and Results of Operations"
    and, with respect to the annual information only, a report thereon by the
    Company's certified independent accountants; and
 
(2) all current reports that would be required to be filed with the SEC on Form
    8-K if the Company were required to file such reports, in each case within
    the time periods specified in the SEC's rules and regulations; PROVIDED that
    the foregoing shall not require the Company to furnish separate financial
    results of its Subsidiaries. In addition, the Company will make such
    information available to securities analysts and prospective investors upon
    request. In addition, the Company has agreed that, for so long as any Notes
    remain outstanding, it will furnish to the Trustee, Holders and to
    securities analysts and prospective investors, upon their request, the
    information required to be delivered pursuant to Rule 144A(d)(4) under the
    Securities Act.
 
DEFAULTS
 
    Each of the following is an Event of Default:
 
(1) a default in the payment of interest on the Notes when due, continued for 30
    days (whether or not prohibited by the subordination provisions of the
    Indenture);
 
(2) a default in the payment of principal of any Note when due at its Stated
    Maturity, upon optional redemption, upon required repurchase, upon
    declaration or otherwise (whether or not prohibited by the subordination
    provisions of the Indenture);
 
(3) the failure by the Company to comply with its obligations in the covenants
    described above under the captions "--Change of Control", "--Certain
    Covenants"--Limitations on Sales of Assets and Subsidiary Stock" or
    "--Merger and Consolidation" above;
 
(4) the failure by the Company to comply for 30 days after notice with any of
    its obligations in the covenants described above under the captions
    "--Limitation on Indebtedness", "--Limitation on Liens Securing Subordinated
    Indebtedness", "--Limitation on Other Senior Subordinated Indebtedness",
    "--Limitation on Restricted Payments", "--Limitation on Restrictions on
    Distributions from Restricted Subsidiaries", "--Limitation on Affiliate
    Transactions", "--Future Subsidiary Guarantors", "--Limitation on
    EnviroSystems and the Holding Companies", "--Limitation on Lines of
    Business", "--Limitation on Designations of Unrestricted Subsidiaries", or
    "--SEC Reports";
 
(5) the failure by the Company to comply for 60 days after notice with its other
    covenants, obligations, warranties or agreements contained in the Indenture;
 
(6) Indebtedness of EnviroSystems, the Company or any Subsidiary which is not
    paid within any applicable grace period after final maturity or which is
    accelerated by the Holders thereof because of a default and the total amount
    of such Indebtedness unpaid or accelerated exceeds $10.0 million and such
    default shall not have been cured or such acceleration rescinded (the "cross
    acceleration provision");
 
(7) certain events of bankruptcy, insolvency or reorganization of the Company or
    any Significant Subsidiary (the "bankruptcy provisions");
 
(8) any judgment or decree for the payment of money in excess of $10.0 million
    is rendered against the Company or any Subsidiary and is not discharged and
    either (A) an enforcement proceeding has been
 
                                       98
<PAGE>
    commenced by any creditor upon such judgment or decree or (B) there is a
    period of 60 days following such judgment during which such judgment or
    decree is not discharged, waived or the execution thereof stayed; or
 
(9) any Subsidiary Guarantee of a Significant Subsidiary ceases to be in full
    force and effect or becomes unenforceable or invalid or is declared null and
    void (other than in accordance with the terms of the Subsidiary Guarantee)
    or any Subsidiary Guarantor that is a Significant Subsidiary denies or
    disaffirms its obligations under its Subsidiary Guarantee.
 
    However, a default under clause (4) or (5) will not constitute an Event of
Default until the Trustee or the Holders of 25% in principal amount of the
outstanding Notes notify the Company of the default and the Company does not
cure such default within the time specified after receipt of such notice.
 
    If an Event of Default (other than the bankruptcy provisions relating to the
Company or any Significant Subsidiary) occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the outstanding Notes may
declare the principal of and accrued but unpaid interest on all the Notes to be
due and payable. Upon such a declaration, such principal and interest shall be
due and payable immediately; PROVIDED, HOWEVER, that for so long as the Senior
Secured Credit Facility remains in effect, such declaration shall not become
effective until the earlier of five Business Days following delivery of notice
to the Representative of such creditors of the intention to accelerate the Notes
or the acceleration of any Indebtedness under the Senior Secured Credit
Facility. If an Event of Default relating to the bankruptcy provisions relating
to the Company or any Significant Subsidiary occurs and is continuing, the
principal of and interest on all the Notes will IPSO FACTO become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. Under certain circumstances, the Holders of a
majority in principal amount of the outstanding Notes may rescind any such
acceleration with respect to the Notes and its consequences.
 
    Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of
principal, premium, if any, or interest when due, no Holder of a Note may pursue
any remedy with respect to the Indenture or the Notes unless:
 
(1) such Holder has previously given the Trustee notice that an Event of Default
    is continuing;
 
(2) Holders of at least 25% in principal amount of the outstanding Notes have
    requested the Trustee to pursue the remedy;
 
(3) such Holders have offered the Trustee reasonable security or indemnity
    against any loss, liability or expense;
 
(4) the Trustee has not complied with such request within 60 days after the
    receipt thereof and the offer of security or indemnity; and
 
(5) the Holders of a majority in principal amount of the outstanding Notes have
    not given the Trustee a direction inconsistent with such request within such
    60-day period.
 
    Subject to certain restrictions, the Holders of a majority in principal
amount of the outstanding Notes are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or of exercising any trust or power conferred on the Trustee. The Trustee,
however, may refuse to follow any direction that conflicts with law or the
Indenture or that the Trustee reasonably determines is unduly prejudicial to the
rights of any other Holder or that would involve the Trustee in personal
liability.
 
                                       99
<PAGE>
    The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each Holder notice of the Default
within 90 days after it occurs. Except in the case of a Default in the payment
of principal of or interest on any Note, the Notes Trustee may withhold notice
if and so long as the board of directors, the executive committee or a committee
of its trust officers reasonably determines that withholding notice is in the
best interest of the Holders. In addition, the Company is required to deliver to
the Trustee, within 120 days after the end of each fiscal year, a certificate
indicating whether the signers thereof know of any Default that occurred during
the previous year. The Company also is required to deliver to the Trustee,
within 30 days after the occurrence thereof, written notice of any event which
would constitute certain Defaults, their status and what action the Company is
taking or proposes to take in respect thereof.
 
AMENDMENTS, SUPPLEMENTS AND WAIVERS
 
    Subject to certain exceptions, the Indenture may be amended or supplemented
with the consent of the Holders of a majority in principal amount of the Notes
then outstanding (including consents obtained in connection with a tender offer
or exchange for the Notes) and, subject to certain exceptions, any past default
or compliance with any provisions may also be waived with the consent of the
Holders of a majority in principal amount of the Notes then outstanding.
 
    Without the consent of each Holder of an outstanding Note affected thereby,
no amendment or supplement may:
 
(1) reduce the amount of Notes whose Holders must consent to an amendment,
    supplement or waiver;
 
(2) reduce the rate of or extend the time for payment of interest on any Note;
 
(3) reduce the principal of or extend the Stated Maturity of any Note;
 
(4) alter the provisions with respect to the mandatory redemption of the Notes
    or the redemption of the Notes at the option of the Company in a manner
    adverse to the Holders;
 
(5) waive a Default or Event of Default in the payment of principal of, premium,
    if any, or interest on, the Notes;
 
(6) waive a mandatory redemption payment with respect to any Note;
 
(7) make any Note payable in money or payable in a place other than that stated
    in the Note;
 
(8) impair the right of any Holder to receive payment of principal of and
    interest on such Holder's Notes on or after the due dates therefor or to
    institute suit for the enforcement of any payment on or with respect to such
    Holder's Notes;
 
(9) make any change in the amendment provisions which require each Holder's
    consent or in the waiver provisions;
 
(10) make any change to the subordination provisions (including definitions) of
    the Indenture that would adversely affect the Holders; or
 
(11) make any change in any Subsidiary Guarantee that would adversely affect the
    Holders.
 
    Without the consent of any Holder, the Company and the Trustee may amend or
supplement the Indenture to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation of the
obligations of the Company under the Indenture, to provide for uncertificated
Notes in addition to or in place of certificated Notes (PROVIDED that the
uncertificated Notes are issued in registered form for purposes of Section
163(f) of the Code, or in a manner such that the uncertificated Notes are
described in Section 163(f)(2)(B) of the Code), to add guarantees with respect
to the Notes, to secure the Notes, to add to the covenants of the Company for
the benefit of the Holders or to surrender any right or power conferred upon the
Company, to make any change that does not adversely affect the
 
                                      100
<PAGE>
rights of any Holder or to comply with any requirement of the SEC in connection
with the qualification of the Indenture under the Trust Indenture Act. However,
no amendment may be made to the subordination provisions of the Indenture that
adversely affects the rights of any Holder of Senior Indebtedness of the Company
or any Restricted Subsidiary then outstanding unless the Holders of such Senior
Indebtedness (or their Representative) consent to such change.
 
    The consent of the Holders is not necessary under the Indenture to approve
the particular form of any proposed amendment or supplement. It is sufficient if
such consent approves the substance of the proposed amendment or supplement.
 
    After an amendment or supplement under the Indenture becomes effective, the
Company is required to mail to Holders a notice briefly describing such
amendment or supplement. However, the failure to give such notice to all
Holders, or any defect therein, will not impair or affect the validity of the
amendment or supplement.
 
TRANSFER
 
    The registered holder of a Note is treated as the owner of it for all
purposes. The Notes are issued in registered form and are transferable only upon
the surrender of the Notes being transferred for registration of transfer. The
Company may require payment of a sum sufficient to cover any tax, assessment or
other governmental charge payable in connection with certain transfers and
exchanges.
 
DEFEASANCE
 
    The Company at its option at any time may terminate all of its obligations
under the Notes and the Indenture ("legal defeasance"). In addition, the Company
at its option at any time may terminate its obligations under "Change of
Control" and under the covenants described under the caption "--Certain
Covenants" (other than the covenant described under "--Merger and
Consolidation") (and any omission to comply with such obligations shall not
constitute a Default or Event of Default with respect to the Notes), and the
limitations contained in clause (3) of the first paragraph of the covenant
described under the caption "--Certain Covenants--Merger and Consolidation"
above ("covenant defeasance"). Despite either a legal or covenant defeasance
certain obligations, including, but not limited to, those respecting the
defeasance trust and obligations to register the transfer or exchange of the
Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a
registrar and paying agent in respect of the Notes shall remain in effect. In
the event that a covenant defeasance occurs, certain events (not including
non-payment, bankruptcy and insolvency events) described under "--Defaults" will
no longer constitute Events of Default with respect to the Notes.
 
    The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises either its
legal defeasance option or its covenant defeasance option, each Subsidiary
Guarantor will be released from all of its obligations with respect to its
Subsidiary Guarantee.
 
    In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations in such amounts as will be sufficient, in the opinion of
a nationally recognized firm of independent public accountants or a nationally
recognized investment banking firm, to pay and discharge the principal of,
premium, if any, and interest on the outstanding Notes to redemption or
maturity, as the case may be, and must comply with certain other conditions,
including delivery to the Trustee of an Opinion of Counsel to the effect that
Holders will not recognize income, gain or loss for Federal income tax purposes
as a result of such deposit and defeasance and will be subject to Federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and defeasance had not occurred (and, in the
case of
 
                                      101
<PAGE>
legal defeasance only, such Opinion of Counsel must be based on a ruling of the
Internal Revenue Service or other change in applicable Federal income tax law).
 
    If the funds deposited with the Trustee to effect legal defeasance or
covenant defeasance are insufficient to pay the principal of, premium, if any,
and interest on the Notes when due, then the obligations of the Company and the
Subsidiary Guarantors under the Indenture will be revived and no such defeasance
will be deemed to have occurred.
 
CONCERNING THE TRUSTEE
 
    United States Trust Company of Texas, N.A. is the Trustee under the
Indenture and has been appointed by the Company as Registrar and Paying Agent
with regard to the Notes. Such bank may also act as a depositary of funds for,
or make loans to and perform other services for, the Company or its Affiliates
in the ordinary course of business in the future.
 
    The Holders of a majority in principal amount of the outstanding Notes are
given the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that if an Event of Default occurs
(and is not cured), the Trustee will be required, in the exercise of its power,
to use the degree of care of a prudent man in the conduct of his own affairs.
Subject to such provisions, the Trustee will be under no obligation to exercise
any of its rights or powers under the Indenture at the request of any Holder of
Notes, unless such Holder shall have offered to the Trustee security and
indemnity satisfactory to it against any loss, liability or expense and then
only to the extent required by the terms of the Indenture. The Trustee may
resign at any time or may be removed by the Company. If the Trustee resigns, is
removed or becomes incapable of acting as Trustee or if a vacancy occurs in the
office of the Trustee for any cause, a successor Trustee shall be appointed in
accordance with the provisions of the Indenture.
 
    If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and the Indenture. The Indenture also
contains certain limitations on the right of the Trustee, as a creditor of the
Company, to obtain payment of claims in certain cases, or to realize on certain
property received by it in respect of any such claims, as security or otherwise.
 
GOVERNING LAW
 
    The Indenture, the Guarantees and the Notes are governed by, and construed
in accordance with, the laws of the State of New York without giving effect to
applicable principles of conflicts of law to the extent that the application of
the law of another jurisdiction would be required thereby.

    other corporation (the "parent corporation") so long as Alchemy beneficially
    own (as so defined), directly or indirectly, in the aggregate a majority of

(2) Following the first Initial Equity Offering, any "person" (as such term is
    used in Sections 13(d) and 14(d) of the Exchange Act), other than Alchemy,
    is or becomes the beneficial owner (as defined in clause (1) above, except
    that for purposes of this clause (2) such person shall be deemed to have

    the purposes of this clause (2), such other person shall be deemed to
    beneficially own any Voting Stock of a specified corporation held by a
    parent corporation, if such other person is the beneficial owner (as defined
    in this clause (2)), directly or indirectly, of more than 35% of the voting
    power of the Voting Stock of such parent corporation and Alchemy
    beneficially owns (as defined in clause (1) above), directly or indirectly,
    in the aggregate a lesser percentage of the voting power of the Voting Stock
    of such parent corporation and do not have the right or ability by voting
    power, contract or otherwise to elect or designate for election a majority
    of the board of directors of such parent corporation);
 
(3) during any period of two consecutive years, individuals who at the beginning
    of such period constituted the Board of Directors or the board of directors
    of EnviroSystems, as the case may be, (together with any new directors whose
    election or appointment by the Board of Directors or the board of directors
    of EnviroSystems, as the case may be, or whose nomination for election by
    the shareholders of the Company or EnviroSystems, as the case may be, was
    approved by a vote of 60% of the directors of the Company or EnviroSystems,
    as the case may be, then still in office who were either directors at the
    beginning of such period or whose election or nomination for election was
    previously so approved) cease for any reason to constitute a majority of the
    Board of Directors or the board of directors of EnviroSystems, as the case
    may be, then in office; or
 
(4) the merger or consolidation of the Company or EnviroSystems with or into
    another Person or the merger of another Person with or into the Company or
    EnviroSystems, or the sale of all or substantially all the assets of the
    Company or EnviroSystems to another Person (other than a Person that is
    controlled by Alchemy), and, in the case of any such merger or
    consolidation, the securities of the Company or EnviroSystems that are
    outstanding immediately prior to such transaction and which represent 100%
    of the aggregate voting power of the Voting Stock of the Company or
    EnviroSystems are changed into or exchanged for cash, securities or
    property, unless pursuant to such transaction such securities are changed
    into or exchanged for, in addition to any other consideration, securities of
    the surviving corporation that represent immediately after such transaction,
    at least a majority of the aggregate voting power of the Voting Stock of the
    surviving corporation.
 
    The phrase "all or substantially all" of the assets of the Company or
EnviroSystems will likely be interpreted under applicable state law and will be
dependent upon particular facts and circumstances. As a result, there may be a
degree of uncertainty in ascertaining whether a sale or transfer of "all or
substantially all" of the assets of the Company or EnviroSystems has occurred.
 
    "Code" means the Internal Revenue Code of 1986, as amended.

    since the beginning of such period and on or prior to the relevant date of
    determination that remains outstanding or if the transaction giving rise to
    the need to calculate the Consolidated Cash Flow Coverage Ratio is an
    issuance of Indebtedness, or both, Cash Flow and Consolidated Interest
    Expense for such period shall be calculated after giving effect on a pro
    forma basis to such Indebtedness as if such Indebtedness had been issued on
    the first day of such period and the discharge of any other Indebtedness
    repaid, repurchased, defeased or otherwise discharged with the proceeds of
    such new Indebtedness as if such discharge had occurred on the first day of
    such period;
 
(2) if since the beginning of such period and on or prior to the relevant date
    of determination, the Company or any Restricted Subsidiary shall have made
    any Asset Disposition, the Cash Flow for such period shall be reduced by an
    amount equal to the Cash Flow (if positive) directly attributable to the
    assets which are the subject of such Asset Disposition for such period, or

    Stock of any Restricted Subsidiary is sold, the Consolidated Interest

    Restricted Subsidiary to the extent the Company and its continuing
    Restricted Subsidiaries are no longer liable for such Indebtedness after
    such sale);
 
(3) to the extent not duplicative with (2) above, if since the beginning of such
    period and on or prior to the relevant date of determination, any Emissions
    Contract ceased or ceases to be in effect, the Cash Flow for such period
    shall be reduced by an amount equal to the Cash Flow (if positive) directly
    attributable to such Emissions Contract for such period, or increased by an
    amount equal to the Cash Flow (if negative), directly attributable thereto
    for such period, and Consolidated Interest Expense for such period shall be
    reduced by an amount equal to the Consolidated Interest Expense directly
    attributable to any Indebtedness of the Company or any Restricted Subsidiary
    repaid, repurchased, defeased or otherwise discharged with respect to the
    Company and its Restricted Subsidiaries with the proceeds of any termination
    fee or similar payment received by the Company or a Restricted Subsidiary as
    a result of the cessation of such Emissions Contract;
 
(4) if since the beginning of such period and on or prior to the relevant date
    of determination, the Company or any Restricted Subsidiary (by merger or
    otherwise) shall have made an Investment in any Restricted Subsidiary (or
    any Person which becomes a Restricted Subsidiary) or an acquisition of
    assets (including Capital Stock of a Subsidiary), including any acquisition
    of assets occurring in connection with a transaction causing a calculation
    to be made hereunder, Cash Flow and Consolidated Interest Expense for such
    period shall be calculated after giving pro forma effect thereto (including
    the issuance of any Indebtedness and including pro forma cost reductions, in
    each case as calculated in accordance with the applicable accounting
    requirements of Rule 11-02 of Regulation S-X under the Securities Act or any
    successor provision relating to the preparation of pro forma financial
    statements (it being understood that all cost reductions set forth in Note
    (3) to the unaudited pro forma consolidated statements included in the
    prospectus shall be deemed to be calculated on a basis
 
                                      107

    consistent with such requirements)) as if such Investment or acquisition
    occurred on the first day of such period; and
 
(5) if since the beginning of such period and on or prior to the relevant date
    of determination, any Person (that subsequently became a Restricted
    Subsidiary or was merged with or into the Company or any Restricted
    Subsidiary since the beginning of such period) shall have made any Asset
    Disposition or any Investment, or any Emissions Contract entered into by
    such Person shall cease to be in effect, that would have required an
    adjustment pursuant to clause (2), (3) or (4) above if made by, or if in
    respect of, the Company or a Restricted Subsidiary during such period, Cash
    Flow and Consolidated Interest Expense for such period shall be calculated

For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto, and
the amount of Consolidated Interest Expense associated with any Indebtedness
issued in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting officer of the Company.
If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest of such Indebtedness shall be calculated as if the
rate in effect on the date of determination had been the applicable rate for the
entire period (taking into account any Interest Rate Protection Agreement
applicable to such Indebtedness if such Interest Rate Protection Agreement has a
remaining term in excess of 12 months). For purposes of this definition,
whenever pro forma effect is to be given to any Indebtedness Incurred pursuant
to a revolving credit facility the amount outstanding under such Indebtedness

commencing on the first day of the first of the four most recent fiscal quarters

    purposes of this definition, interest expense attributable to any

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    In the opinion of White & Case LLP, special tax counsel to the Company, the
following is a description of the principal United States federal income tax
consequences that may be relevant to the registration of the notes and the
purchase, ownership and sale of the notes. This description is based on (1) the
Internal Revenue Code of 1986, as amended (the "Code"), (2) income tax
regulations (proposed and final) issued under the Code, and (3) administrative
and judicial interpretations of the Code and regulations, each as in effect and
available as of the date of this prospectus. These income tax laws, regulations,
and interpretations, however, may change at any time. Any change could be
retroactive and could affect the tax consequences described below. These income
tax laws and regulations are also subject to various interpretations, and the
Internal Revenue Service (the "IRS") or the courts could later disagree with the
explanations or conclusions contained in this summary. The IRS has not formally
ruled (and we do not intend to seek a ruling) on the tax consequences of
purchasing, holding or selling the notes. Accordingly, the IRS could challenge
the opinions expressed in this prospectus concerning such consequences, and a
court could agree with the IRS.
 
    A "U.S. Holder" is a Note holder who or which for United States federal
income tax purposes is:
 
    - a United States citizen or resident individual;
 
    - a corporation or partnership created or organized in or under the laws of
      the United States;
 
    - an estate if its income is subject to United States federal income
      taxation regardless of its source; or
 
    - a trust if such trust has validly elected to be treated as a United States
      person for United States federal income tax purposes or if (1) a United
      States court can exercise primary supervision over its administration and
      (2) one or more United States persons have the authority to control all of
      its substantial decisions.
 
    We do not address all of the tax consequences that may be relevant to a
holder. We also do not address, except as stated below, any of the tax
consequences to (1) holders that do not hold notes as capital assets (as defined
in the Code), (2) holders that may be subject to special tax treatment such as
financial institutions, thrift institutions, real estate investment trusts,
tax-exempt organizations, regulated investment companies, insurance companies
and brokers and dealers or traders in securities or currencies, (3) holders
whose functional currency is not the United States dollar and (4) holders that
hold notes as part of a position in a straddle or as part of a hedging,
conversion or other integrated investment transaction. Further, except as stated
below, we do not address:
 
    - the United States federal estate and gift or alternative minimum tax
      consequences of the ownership or sale of notes or
 
    - any state, local or foreign tax consequences of the ownership and sale of
      notes.
 
    INVESTORS ARE ADVISED TO CONSULT WITH THEIR OWN TAX ADVISORS IN LIGHT OF
THEIR OWN PARTICULAR CIRCUMSTANCES AS TO THE UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES OF HOLDING AND DISPOSING OF NOTES, AS WELL AS THE EFFECT OF ANY
STATE, LOCAL OR FOREIGN TAX LAWS.
 
ISSUANCE OF THE NOTES
 
    The Notes were originally sold to the selling noteholders pursuant to a
private placement as part of an investment unit. Each investment unit was
comprised of an unregistered note and common stock of Envirosystems. Although
not free from doubt, the Notes should be considered to have been issued with
original issue discount at such time. This discussion assumes that the notes
will be considered to have been issued with original issue discount at such time
for United States federal income tax purposes.
 
                                      121
<PAGE>
REGISTRATION OF THE NOTES
 
    The registration of the notes will not constitute a material modification of
the Notes and thus, will not constitute a taxable exchange for United States
federal income tax purposes. A U.S. Holder will not recognize gain or loss upon
the receipt of a registered Note pursuant to this registration and will be
required to continue to include interest on the notes in gross income for United
States federal income tax purposes in the same manner as such interest was
included in income under the unregistered notes.
 
THE NOTES
 
U.S. HOLDERS
 
    STATED INTEREST.  Stated interest paid on a Note will be includible in a
U.S. Holder's gross income as ordinary interest income in accordance with the
U.S. Holder's usual method of tax accounting.
 
    ORIGINAL ISSUE DISCOUNT.  The Notes should be considered to have been issued
with original issue discount ("OID"), as such term is defined in the Code and
the income tax regulations. As a result, a U.S. Holder generally is required to
include OID in gross income (as interest) for United States federal income tax
purposes as it economically accrues, in advance of the receipt of the cash
attributable to such income. The amount included in gross income will be the sum
of the daily portions of OID on a Note calculated under a constant yield method
for all days during a taxable year in which a U.S. Holder owns such Note.
 
    The amount of OID on a Note allocable to an accrual period generally is
determined by multiplying its "adjusted issue price" (as defined below) at the
beginning of the accrual period by the Note's yield to maturity (adjusting the
yield to take into account the length of the particular accrual period).
Generally, an accrual period is any period elected by a U.S. Holder, provided
that each accrual period is no longer than one year and that each interest
payment date is the first or last day of the accrual period.
 
    The "adjusted issue price" of a Note at the beginning of any accrual period
will be the sum of its issue price and the amount of OID allocable to all prior
accrual periods, reduced by the amount of all payments other than qualified
stated interest payments made with respect to such Note in all prior accrual
periods. The Notes were initially issued to the selling noteholders as part of
an investment unit consisting of a Note and EnviroSystems Corp. common stock.
The issue price of such investment unit for United States federal income tax
purposes was $1,000 which was allocated between the Note and the EnviroSystems
Corp. common stock based on their respective fair market values at the time of
issuance and a holder's initial tax basis in each is equal to the amount so
allocated. Based upon the estimate of the fair market value of the common stock,
the Company is treating $66 of the issue price of the investment unit as
allocable to the common stock and $934 as allocable to the Note (which amount
the Company will therefore treat as its issue price for United States federal
income tax purposes). The Company intends to file information returns with the
Internal Revenue Service (the "IRS") based on such allocation.
 
    "Qualified stated interest" generally is stated interest that is
unconditionally payable in cash or property (other than debt instruments of the
issuer) at least annually at a single fixed rate during the entire term of the
debt instrument. All of the stated interest on a Note should be treated as
qualified stated interest. Accordingly, since all of the stated interest on a
Note is qualified stated interest, the total amount of OID on a Note at issuance
should be $66 (representing the difference between a Note's principal amount and
issue price).
 
    A U.S. Holder will be required to include in gross income (as interest), in
the manner set forth above, (i) stated interest payments on a Note and (ii) OID
accruing on such Note.
 
    PREMIUM AND MARKET DISCOUNT.  A U.S. Holder that purchases a Note at a cost
greater than its adjusted issue price will be considered to have purchased the
Note at a premium and may make an election an election, applicable to all debt
securities purchased at a premium and held by such holder, to amortize such
premium, using a constant yield method, over the remaining term of the Note.
 
                                      122
<PAGE>
    A U.S. Holder that purchases a Note at a price that produces a yield to
maturity higher than the yield to maturity at which the note was first issued
will be considered to have purchased a note having market discount. Generally,
market discount is the amount by which the stated redemption price at maturity
of a note exceeds its purchase price. Gain realized by such U.S. Holder on the
sale (including a redemption for cash) of a Note having market discount
generally will be treated as ordinary income to the extent of the market
discount that accrued on the Note while held by such holder. In general, market
discount will be treated as accruing ratably over the term of the Note, or, at
the election of the holder, under a constant yield method. Moreover, a holder of
a note having market discount could be required to defer the deduction of a
portion of the interest paid on any indebtedness incurred or continued to
purchase or hold a note (unless the holder elects to include such market
discount in income as its accrues).
 
    SALE, EXCHANGE OR RETIREMENT.  Subject to the discussion of market discount,
upon the sale (including a redemption for cash) of a Note, a U.S. Holder will
recognize taxable gain or loss equal to the difference, if any, between the
amount realized on the sale (other than, accrued but unpaid interest which will
be taxable as ordinary income) and the U.S. Holder's adjusted tax basis in such
Note. A U.S. Holder's adjusted tax basis generally will equal the cost of such
Note increased by any amounts includible in income by the holder as original
issue discount or market discount (if the U.S. Holder elects to include such
market discount in income on a current basis) and decreased by any amortized
premium, if any. Except as discussed above under "PREMIUM AND MARKET DISCOUNT",
the gain or loss recognized by a U.S. Holder will be capital gain or loss.
Moreover, in the case of a U.S. Holder that is not a corporation, the maximum
marginal United States federal income tax rate applicable to such capital gain
will be lower than the maximum marginal United States federal income tax rate
applicable to ordinary income if such U.S. Holder's holding period for such Note
exceeds one year.
 
NON-U.S. HOLDERS
 
    INTEREST ON NOTES.  Subject to the discussion under "United States Backup
Withholding Tax and Information Reporting" below, interest paid on a note to a
Non-U.S. Holder (other than, (a) a controlled foreign corporation related to the
Company by stock ownership, (b) a shareholder owning actually or constructively
10% or more of the total combined voting power of all classes of stock of the
Company entitled to vote or (c) a bank which acquired such Notes in
consideration of an extension of credit made pursuant to a loan agreement
entered into in the ordinary course of business) will not be subject to United
States federal income or withholding tax provided that (i) such interest is not
effectively connected with the conduct of a trade or business within the United
States by such Non-U.S. Holder and (ii) valid certifications of non-United
States status are received or an exemption is otherwise established.
 
    If a Non-U.S. Holder is engaged in a trade or business in the United States
and interest on the Note is effectively connected with the conduct of such trade
or business, the Non-U.S. Holder will be subject to United States federal income
tax on such interest on a net income basis in the same manner as if it were a
U.S. Holder. In addition, if such holder is a foreign corporation, it may be
subject to a branch profits tax equal to 30% (or lower applicable treaty rate)
of its effectively connected earnings and profits, including interest on a note,
for the taxable year, subject to adjustments.
 
    SALE, EXCHANGE OR RETIREMENT.  A Non-U.S. Holder generally will not be
subject to United States federal income tax on gain recognized on a sale
(including a redemption for cash) of a Note unless (i) such gain is effectively
connected with the conduct of a trade or business within the United States by
the Non-U.S. Holder or (ii) in the case of an individual Non-U.S. Holder, such
holder is present in the United States for 183 or more days in the taxable year
of disposition and certain other requirements are met.
 
    FEDERAL ESTATE TAXES.  A Note that is held by an individual who at the time
of death is not a citizen or resident of the United States will not be subject
to United States federal estate tax as a result of such individual's death,
provided that such individual is not a shareholder owning actually or
constructively 10% (or more) of the total combined voting power of all classes
of stock of the Company entitled to vote and, at
 
                                      123
<PAGE>
the time of such individual's death, payments of interest with respect to such
Notes would not have been effectively connected with the conduct by such
individual of a trade or business in the United States.
 
UNITED STATES BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
    Certain noncorporate holders of Notes may be subject to backup withholding
at a rate of 31% on payments made on a Note. Backup withholding will apply to
you only if you are a United States person (as defined in the Code) and you (i)
fail to furnish your Taxpayer Identification Number ("TIN") which, in the case
of an individual, would be your Social Security number, (ii) furnish an
incorrect TIN, (iii) are notified by the IRS that you have failed to properly
report payments of interest or dividends or (iv) under certain circumstances,
fail to certify, under penalty of perjury, that you furnished a correct TIN and
have not been notified by the IRS that it is subject to backup withholding. The
amounts withheld under the backup withholding rules are not an additional tax
and may be refunded, or credited against your United States federal income tax
liability provided that the required information is furnished to the IRS.
Further, information reporting will apply to such payments.
 
    THE ABOVE DESCRIPTION IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF
ALL TAX CONSEQUENCES RELATING TO THE REGISTRATION OF THE NOTES AND TO THE
ACQUISITION, OWNERSHIP AND SALE OF NOTES. ACCORDINGLY, YOU ARE URGED TO CONSULT
YOUR OWN TAX ADVISORS TO DETERMINE THE UNITED STATES FEDERAL, STATE, LOCAL AND
FOREIGN TAX CONSEQUENCES RELATING TO THE REGISTRATION OF THE NOTES AND THE
ACQUISITION, OWNERSHIP AND SALE OF NOTES IN LIGHT OF YOUR PARTICULAR SITUATIONS.

                         BOOK-ENTRY; DELIVERY AND FORM
 
GENERAL
 
    Except as set forth below, the Notes will be represented by one permanent
global registered note in global form, without interest coupons. The global note
will be deposited with, or on behalf of, The Depository Trust Company and
registered in the name of Cede & Co., as nominee of The Depository Trust
Company, or will remain in the custody of the Trustee according to the FAST
Balance Certificate Agreement between The Depository Trust Company and the
Trustee.
 
    We are providing the following descriptions of the operations and procedures
of The Depository Trust Company, Euroclear [and Cedel] solely as a matter of
convenience. These operations and procedures are solely within the control of
the respective settlement systems and are subject to change by them from time to
time. Neither we nor Credit Suisse First Boston Corporation take any
responsibility for these operations or procedures. If you wish to discuss these
matters, we urge you to contact the relevant system or its participants
directly.
 
    The Depository Trust Company has advised us that it is:
 
    - a limited purpose trust company organized under the laws of the State of
      New York;
 
    - a "banking organization" within the meaning of the New York Banking Law;
 
    - a member of the Federal Reserve System;
 
    - a "clearing corporation" within the meaning of the Uniform Commercial
      Code, as amended; and
 
    - a "clearing agency" registered pursuant to Section 17A of the Exchange
      Act.
 
    The Depository Trust Company was created to hold securities for its
participants and facilitates the clearance and settlement of securities
transactions between participants through electronic book-entry changes to the
accounts of its participants. This system eliminates the need for physical
transfer and delivery of certificates. The Depository Trust Company's
participants include:
 
    - securities brokers and dealers (including Credit Suisse First Boston
      Corporation);
 
    - banks and trust companies;
 
    - clearing corporations; and
 
    - certain other organizations.
 
    Indirect access to The Depository Trust Company's system is also available
to other entities. These indirect participants include banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a participant, either directly or indirectly. Investors who are not participants
may beneficially own securities held by or on behalf of The Depository Trust
Company only through participants or indirect participants.
 
    We expect that under the procedures established by The Depository Trust
Company:
 
    - upon deposit of the global note, The Depository Trust Company will credit
      the accounts of participants designated by Credit Suisse First Boston
      Corporation with an interest in the global note; and
 
    - ownership of the Notes will be shown on, and the transfer of ownership
      thereof will be effected only through, records maintained by The
      Depository Trust Company (with respect to the interests of participants)
      and the records of participants and the indirect participants (with
      respect to the interests of persons other than participants).
 
                                      125
<PAGE>
    The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the Notes represented by the
global note to such persons may be limited. In addition, The Depository Trust
Company can act only on behalf of its participants, who in turn act on behalf of
persons who hold interests through participants. Consequently, the ability of a
person having an interest in Notes represented by the global note to pledge or
transfer such interest to persons or entities that do not participate in The
Depository Trust Company's system, or to otherwise take actions in respect of
such interest, may be affected by the lack of a physical definitive security in
respect of such interest.
 
    So long as The Depository Trust Company or its nominee is the registered
owner of the global note, The Depository Trust Company or such nominee, as the
case may be, will be considered the sole owner or holder of the Notes
represented by the global note for all purposes under the Indenture. Except as
provided below, owners of beneficial interests in the global note:
 
    - will not be entitled to have Notes represented by the global note
      registered in their names;
 
    - will not receive or be entitled to receive physical delivery of
      certificated Notes; and
 
    - will not be considered the owners or holders thereof under the indenture
      for any purpose, including with respect to the giving of any direction,
      instruction or approval to the Trustee thereunder.
 
    Accordingly, each holder owning a beneficial interest in the global note
must rely on the procedures of The Depository Trust Company. If such holder is
not a participant or an indirect participant, then it must rely on the
procedures of the participant through which such holder owns its interest to
exercise any rights of a Note holder under the indenture or the global note. We
understand that under existing industry practice, in the event that we request
any action of Note holders, or a holder that is an owner of a beneficial
interest in the global note desires to take any action that The Depository Trust
Company, as the holder of the global note, is entitled to take, The Depository
Trust Company would authorize the participants to take such action and the
participants would authorize holders owning through such participants to take
such action or would otherwise act upon the instruction of such holders. Neither
our Company nor the Trustee will have any responsibility or liability for any
aspect of the records relating to or payments made on account of Notes by The
Depository Trust Company, or for maintaining, supervising or reviewing any
records of The Depository Trust Company relating to such Notes.
 
    Payments with respect to the principal of, and premium, if any, and interest
on, any Notes represented by the global note registered in the name of The
Depository Trust Company or its nominee on the applicable record date will be
payable by the Trustee to or at the direction of The Depository Trust Company or
its nominee in its capacity as the registered holder of the global note
representing such Notes under the indenture. Under the terms of the indenture,
we and the Trustee may treat the persons in whose names the Notes, including the
global note, are registered as the owners of the Notes for the purpose of
receiving payment on the Notes and for any and all other purposes whatsoever.
Accordingly, neither our Company nor the Trustee has or will have any
responsibility or liability for the payment of such amounts to owners of
beneficial interests in a global note (including principal, premium, if any, and
interest). Payments by the participants and the indirect participants to the
owners of beneficial interests in a global note will be governed by standing
instructions and customary industry practice and will be the responsibility of
the participants or the indirect participants and The Depository Trust Company.
 
    Transfers between participants in The Depository Trust Company will be
effected in accordance with The Depository Trust Company's procedures, and will
be settled in same-day funds. Transfers between participants in Euroclear or
Cedel will be effected in the ordinary way in accordance with their respective
rules and operating procedures.
 
    Subject to compliance with the transfer restrictions applicable to the
Notes, cross-market transfers between the participants in The Depository Trust
Company and Euroclear or Cedel participants will be effected through The
Depository Trust Company in accordance with its rules on behalf of Euroclear or
 
                                      126
<PAGE>
Cedel by its respective depositary. However, such cross-market transactions will
require delivery of instructions to Euroclear or Cedel by the counterparty in
such system in accordance with the rules and procedures and within the
established deadlines (Brussels time) of such system. Euroclear or Cedel will,
if the transaction meets its settlement requirements, deliver instructions to
its respective depositary to take action to effect final settlement on its
behalf by delivering or receiving interests in the relevant global notes in The
Depository Trust Company, and making or receiving payment in accordance with
normal procedures for same-day funds settlement applicable to The Depository
Trust Company. Euroclear participants and Cedel participants may not deliver
instructions directly to the depositaries for Euroclear or Cedel.
 
    Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in the global note from a participant
in The Depository Trust Company will be credited, and any such crediting will be
reported to the relevant Euroclear or Cedel participant, during the securities
settlement processing day (which must be a business day for Euroclear and Cedel)
immediately following the settlement date of The Depository Trust Company. Cash
received in Euroclear or Cedel as a result of sales of interest in the global
note by or through a Euroclear or Cedel participant to a participant in The
Depository Trust Company will be received with value on the settlement date of
The Depository Trust Company but will be available in the relevant Euroclear or
Cedel cash account only as of the business day for Euroclear or Cedel following
The Depository Trust Company's settlement date.
 
    Although The Depository Trust Company, Euroclear and Cedel have agreed to
the foregoing procedures to facilitate transfers of interests in the global note
among participants in The Depository Trust Company, Euroclear and Cedel, they
are under no obligation to perform or to continue to perform such procedures,
and such procedures may be discontinued at any time. Neither our company nor the
Trustee will have any responsibility for the performance by The Depository Trust
Company, Euroclear or Cedel or their respective participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
CERTIFICATED NOTES
 
    Certificated Notes will be issued to each person that The Depository Trust
Company identifies as the beneficial owner of the Notes represented by the
global Note if the following events occur:
 
    - The Depository Trust Company notifies us that it is no longer willing or
      able to act as a depositary or The Depository Trust Company ceases to be
      registered as a clearing agency under the Securities Exchange Act of 1934
      and a successor depositary is not appointed within 90 days of such notice
      or cessation;
 
    - we, at our option, notify the Trustee in writing that we elect to cause
      the issuance of certificated Notes under the indenture; or
 
    - upon the occurrence of an event of default as provided in the indenture
      occurs and is continuing in the indenture, then, upon surrender by The
      Depository Trust Company of the global note.
 
    Upon any such issuance, the Trustee shall register such certificated Notes
in the name of such person or persons (or any nominee) and deliver the
certificated Notes as instructed.
 
    Neither we nor the Trustee shall be liable for any delay by The Depository
Trust Company or any participant or indirect participant in identifying the
beneficial owners of the related Notes. Each person may conclusively rely on,
and shall be protected in relying on, instructions from The Depository Trust
Company for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Notes to be issued).

                              PLAN OF DISTRIBUTION
 
    We are registering the Notes on behalf of the Selling Noteholders. All
costs, expenses and fees in connection with the registration of the Notes
offered hereby will be borne by us. Any or all of the Notes may be sold from
time to time to purchasers directly by the Selling Noteholders. Alternatively,
the Noteholders may, from time to time, offer the Notes through underwriters,
dealers or agents, which may include Credit Suisse First Boston or Donaldson,
Lufkin & Jenrette Securities Corporation ("DLJSC"), who may receive compensation
in the form of discounts, concessions or commissions from the Selling
Noteholders and/or the purchasers of Notes for whom they may act. The Selling
Noteholders have advised us that they have not entered into any agreements,
understandings or arrangements with any underwriters or broker-dealers regarding
the sale of their Notes, nor is there an underwriter or coordinating broker
acting in connection with the proposed sale of the Notes by the Noteholders. All
of the Selling Noteholders are affiliates of broker-dealers. We will not receive
any proceeds from the sale of any of the Notes by any Selling Noteholder.
 
    The Notes were originally issued to the Selling Noteholders in a private
transaction on October 16, 1998. We are registering the Notes to allow the
resale of the Notes, if any, by the Selling Noteholders. We retained Credit
Suisse First Boston to act as our advisor in connection with the private
placement of the Notes, for which Credit Suisse First Boston received $2 million
as compensation. In addition, DLJSC received a $2 million placement fee in
connection with the private placement of the Notes.
 
    There is currently no trading market for the Notes. Furthermore, there can
be no assurance that any trading market will develop, or that, if such market
does develop, it will be sustained.
 
    The Selling Noteholders and any such underwriters, dealers or agents that
participate in the distribution of the Notes might be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by such broker-dealers and any profit on the resale of
the Notes sold by them while acting as principals might be deemed to be
underwriting discounts or commissions under the Securities Act.
 
    Pursuant to a Registration Rights Agreement dated October 16, 1998 among us
and the Selling Noteholders on such date, we agreed to file the Registration
Statement, of which this Prospectus forms a part, with the SEC, and agreed to
use our best efforts to keep the Registration Statement continuously effective
for 180 days from its effective date or until such earlier time as all of the
Notes which may be offered hereby have been publicly sold. Pursuant to the
Registration Rights Agreement, we agreed to indemnify the Selling Noteholders,
any underwriters of an offering made hereby and certain other persons against
certain liabilities, including liabilities under the Securities Act.
 
    Because Selling Noteholders may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, the Selling Noteholders will be
subject to the prospectus delivery requirements of the Securities Act. We have
informed the Selling Noteholders that the anti-manipulative provisions of
Regulation M promulgated under the Exchange Act may apply to their sales in the
market.
 
    Selling Noteholders also may resell all or a portion of the Notes in open
market transactions in reliance upon Rule 144 under the Securities Act, provided
they meet the criteria and conform to the requirements of such Rule.
 
    When we are notified by a Selling Noteholder that a particular offer of
Notes is made, to the extent required, we will file a supplement to this
prospectus, pursuant to Rule 424(b) under the Act, disclosing (i) the name of
each such selling Selling Noteholder and of the participating broker-dealer(s),
(ii) the aggregate principal amount of Notes involved, (iii) the price at which
such Notes were sold, (iv) the commissions paid or discounts or concessions
allowed to such broker-dealer(s), where applicable, (v) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus and (vi) other facts
material to the transaction.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
ENVIRONMENTAL SYSTEMS PRODUCTS, INC. AND SUBSIDIARIES:
 
    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of changes in stockholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Environmental Systems Products, Inc. and its subsidiaries (the "Company") at
December 31, 1997 and 1996, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

1. SIGNIFICANT ACCOUNTING POLICIES:
 
    BUSINESS
 
    Environmental Systems Products, Inc. (the "Company") designs, sells,
services and leases engine diagnostic and automotive emissions test equipment.
For the years ended December 31, 1997, 1996 and 1995, approximately 91%, 83% and
92%, respectively, and for the nine month periods ended September 30, 1998 and
1997, approximately 98% (unaudited) and 82% (unaudited), respectively, of
consolidated sales were in the United States, with the balance being
international, primarily in Mexico and Germany.
 
    ORGANIZATION
 
    The Company was incorporated on November 13, 1989 and effective December 29,
1989, acquired substantially all of the assets and assumed certain liabilities
of Automotive Systems, a business unit of Hamilton Test Systems, Inc., a
wholly-owned subsidiary of United Technologies Corporation. The acquisition was
accounted for as a purchase transaction.
 
    On April 19, 1996, for approximately $16.3 million, all the outstanding
shares of Class A common stock and the 15% convertible preferred stock of the
Company were acquired by Wellman North America, Inc., a wholly-owned subsidiary
of Wellman Overseas Limited, a wholly-owned subsidiary of Wellman plc
(collectively, "Wellman").
 
    In January 1998 Wellman was acquired by unrelated investors, the Alchemy
Plan ("Alchemy"). All of the outstanding common stock of Wellman was acquired
for $127 million. As a result of the purchase, a new basis of accounting was
established. Of the total purchase price of $127 million, $64 million
(unaudited) plus transaction related costs for a total of $69 million
(unaudited) was attributable to the Company. Preliminarily, the purchase price
has been allocated to net tangible assets in the amount of $20 million
(unaudited) and intangible assets in the amount of $49 million (unaudited), with
a resulting adjustment to additional paid-in capital of $50 million (unaudited).
The unaudited balance sheet as of September 30, 1998 includes the aforementioned
adjustments.
 
    SUBSIDIARIES
 
    On March 23, 1992, Environmental Systems Products International was formed
as the Company's foreign sales corporation. On August 4, 1992, E.S.P. de Mexico,
S.A. de C.V. was incorporated to provide service for emissions units sold in
Mexico. On November 16, 1993, ESP-GmbH was incorporated to provide service for
emissions units sold in Germany. On June 23, 1995, Autosense Systems, Ltd. was
formed to provide service for emissions units sold in the United Kingdom. On
April 19, 1996, operating control of this subsidiary was transferred from the
Company to Wellman plc, at book value, which resulted in an increase in the
Company's retained earnings of approximately $511,000.
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.

1. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    FOREIGN CURRENCY MEASUREMENT
 
    The Company translates the assets and liabilities of its foreign
subsidiaries at rates of exchange in effect at the end of the year. Revenues and
expenses are translated at average rates in effect during the year.
 
    In accordance with Statement of Financial Accounting Standards No. 52,
"Foreign Currency Translation", the Company has included the losses resulting
from the intercompany foreign currency transactions in net income. However, the
losses from the translation of the foreign currency financial statements have
been reported as a separate component of stockholders' equity.
 
    REVENUE RECOGNITION
 
    Revenues are derived primarily from companies in the automotive aftermarket.
Amounts billed for service contracts are deferred and recognized as revenue over
the term of the service contract on a straight-line basis. Cash received from
customers in advance of shipment is included in deferred revenue.
 
    CASH AND CASH EQUIVALENTS
 
    Cash equivalents include short-term investments maturing within three
months. As of December 31, 1997 and 1996 and September 30, 1998, cash
equivalents were comprised primarily of repurchase agreements, collateralized by
government securities.
 
    INVENTORIES
 
    Inventories are stated at the lower of cost or market. Cost is determined by
the first-in, first-out method.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost at the time of acquisition.
Depreciation is computed using the straight-line method over the estimated
useful lives of the respective assets as follows:

</TABLE>
 
    At January 23, 1998 the property and equipment acquired by Alchemy was
restated to fair value. The property and equipment acquired are now being
depreciated over their remaining estimated useful lives which are estimated to
be 2-3 years.
 
    Maintenance and repairs are charged to expense as incurred. For assets sold
or otherwise disposed of, the cost and related accumulated depreciation are
removed from the accounts and any resulting gain or loss is recorded in income
for the year. The cost of major improvements is capitalized.

1. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    INTANGIBLE ASSETS
 
    The purchase price paid by Alchemy for the Company in excess of the market
value of net assets acquired has been pushed down to the Company and is included
in the September 30, 1998 consolidated balance sheet as intangible assets.
Intangible assets are being amortized over their estimated useful lives, which
management estimates to be twenty-five years, using the straight-line method. It
is the Company's policy to re-evaluate the estimated useful lives of intangible
assets on an annual basis and may adjust the estimated useful lives accordingly.
It is possible, given the political, legislative and competitive environment in
which the Company operates, that the estimate could change and may result in
accelerated amortization charges.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of cash and cash equivalents, trade accounts
receivable, notes receivable, trade accounts payable, notes payable and accrued
liabilities are a reasonable estimate of their fair value due to their
short-term nature. The estimated values of the Company's long-term debt are
based on interest rates at December 31, for issues with similar remaining
maturities.
 
    The estimated fair value amounts of the Company's financial instruments have
been determined by the Company, using appropriate market information and
valuation methodologies. Considerable judgment is required to develop the
estimates of fair value, therefore the estimates provided here are not
necessarily indicative of the amounts that could be realized in a current market
exchange.
 
    LIABILITY FOR ESTIMATED PRODUCT WARRANTIES
 
    The Company provides warranties for its equipment which range from one to
five years. Costs associated with these programs are provided at the time of
sale of the warranted product and are included in cost of sales. For the years
ended December 31, 1997, 1996 and 1995, approximately $2,406,000, $535,000 and
$291,000, respectively; and for the nine month periods ended September 30, 1998
and 1997, approximately $2,896,000 (unaudited) and $913,000 (unaudited)
respectively, was charged to warranty expense.
 
    INCOME TAXES
 
    The Company uses the liability method of accounting for income taxes as set
forth in Statement of Financial Accounting Statements No. 109, "Accounting for
Income Taxes". Under this method, deferred tax assets and liabilities are
recognized for the expected future tax consequences of temporary differences
between the financial statement carrying amounts and the tax basis of the assets
and liabilities using presently enacted tax rates. The Company files its Federal
income tax return as a member of a consolidated group through its parent. The
tax liability of the group is allocated among its members according to their
respective tax liabilities, computed as though separate returns had been filed,
increased for the additional tax savings resulting from the absorption by one
member of another member's tax attributes.

1. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    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.
 
    Estimates are primarily used in determining valuation allowances for
accounts receivable, inventories, warranty and deferred tax assets. Accrued
expenses for the self funded health insurance benefits include estimates for
claims reported as well as claims incurred but not reported.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" (SFAS 130). SFAS 130 applies to all
companies and is effective for fiscal years beginning after December 15, 1997.
SFAS 130 establishes standards for the reporting and display of comprehensive
income in a set of financial statements. Comprehensive income is defined as the
change in net assets of a business enterprise during a period from transactions
generated from non-owner sources. It includes all changes in equity during a
period except those resulting from investment by owners and distributions to
owners. The Company has adopted SFAS 130 beginning January 1, 1998.
 
    In June 1997, the Financial Accounting Standards Board issued Statement No.
131 "Disclosures about Segments of an Enterprise and Related Information" (SFAS
131). SFAS 131 applies to all public companies and is effective for fiscal years
beginning after December 15, 1997. SFAS 131 requires that business segment
financial information be reported in the financial statements utilizing the
management approach. The management approach is defined as the manner in which
management organizes the segments within the enterprise for making operating
decisions and assessing performance. The Company has adopted SFAS 131 beginning
January 1, 1998. The Company's operations are currently managed all within one
segment.
 
    INTERIM FINANCIAL STATEMENTS
 
    The consolidated financial statements of the Company as of September 30,
1998 and for the nine months ended September 30, 1998 and 1997 are unaudited.
All adjustments, consisting only of normal recurring adjustments, have been made
which, in the opinion of management, are necessary for a fair presentation of
the interim financial information. Results of operations for the nine months
ended September 30, 1998 are not necessarily indicative of the results that may
be expected for any future period. The unaudited consolidated financial
statements for the nine months ended September 30, 1998 include the results of
operations from January 1, 1998 through January 23, 1998, predecessor ownership,
and from January 24, 1998 through September 30, 1998, new ownership, for
comparative purposes with the same period in 1997. The unaudited balance sheet
at September 30, 1998 reflects the new basis of accounting from January 24, 1998
through September 30, 1998.

5. LOAN AND SECURITY AGREEMENT:
 
    The Company has a loan and security agreement including a $10,000,000
revolving credit agreement with Bank One Corporation, formerly known as Banc One
Corporation (the "Bank"). Interest is assessed on borrowings at an annual rate
equal to the Bank's prime rate (8.25% and 8.5% as of December 31, 1997 and 1996,
respectively), plus 0.6 percent. As of December 31, 1997 and 1996, the Company
had borrowings of $9,975,649 and $780,849, respectively, outstanding under this
agreement. The revolving credit agreement provides for borrowings based on 80%
of eligible accounts receivable, plus the lesser of 40% of eligible inventory,
$4,000,000, or 50% of the Revolving Credit Loan.
 
    In October 1997, the Company and the Bank modified the revolving credit
agreement. Maximum borrowings under the revolving credit agreement increased to
$10,000,000 and the agreement was extended to August 31, 1998. The Company has
the option to fix the annual interest rate of certain borrowings for up to 90
days at the LIBOR rate plus 2.55%, if certain conditions are met. The non-LIBOR
borrowings have interest assessed at an annual rate equal to the Bank's prime
rate plus or minus the prime rate margin. The prime rate margin varies from 0.3%
to (0.3%), depending on the Company's leverage ratio. The prime rate margin was
9.4% as of December 31, 1997.
 
    The Company also had a term loan under the loan and security agreement, due
in monthly principal installments of $33,334, plus interest for three years, and
a final principal payment made in 1997. Interest was assessed at an annual rate
equal to the Bank's prime rate plus 0.9 percent. The term loan was
collateralized by all of the Company's assets except those supporting the
revolving credit agreement.
 
    The loan and security agreement requires the Company to maintain a current
ratio of at least 1.2 to 1, keep their leverage ratio below 3.75 to 1, and to
have tangible net worth of not less than $7,000,000.
 
    Cash paid for interest for the years ended December 31, 1997, 1996 and 1995
was $440,964, $122,434 and $188,909, respectively and for the nine month periods
ended September 30, 1998 and 1997, $4,362,678 (unaudited) and $144,784
(unaudited), respectively.
 
    The outstanding balance of the revolving credit agreement was fully repaid
in March 1998. See Note 15 for a discussion of the subsequent refinancing of the
loan and security agreement.

maintained in the Trust account at all times.
 
    The Trust has a year-end of October 31. For the years ended December 31,
1997, 1996 and 1995, the Company costs associated with the Plan were
approximately $561,000, $458,000 and $516,000, respectively; and for the nine
month periods ended September 30, 1998 and 1997, $458,000 (unaudited) and
$321,000 (unaudited), respectively.
 
    The Company has a Plan under Section 401(k) of the Internal Revenue Code
covering all eligible employees. Under the Plan, the Company will match a
certain percentage of an employee's contribution up to a maximum amount. The
Company's matching contribution under the Plan for the years ended December 31,

9. RELATED PARTY TRANSACTIONS: (CONTINUED)
Company accrued approximately $260,000 for management charges payable to Wellman
plc as of December 31, 1996. There were no management charges in 1997. Included
in income taxes payable are taxes payable to Wellman, North America of $297,900
as of December 31, 1997.
 
    The Company had notes receivable from former stockholders and current
officers totaling approximately $69,000 as of December 31, 1996. The notes were
repaid in 1997. In 1995, the Company purchased $207,000 of consulting services

10. MANDATORILY REDEEMABLE PREFERRED STOCK
 
    During 1994, the Company issued 5,000 shares of Class B non-voting $100 par
value Preferred Stock to the Connecticut Development Authority for $500,000. In
April 1997 the Class B Preferred Stock converted to mandatorily redeemable
preferred stock and 1,668 shares were redeemed and retired in 1997 for $166,800
and the remaining 3,332 shares are redeemable in 1998 at $335,699. The Class B
Preferred Stock pays an annual dividend when and if declared, on a
non-cumulative basis, equal to 5% of the par value per share. The distribution
rights of this preferred stock were subordinate to those of the 15% convertible
preferred stock, but superior to those of the Class A Common Stock.
 
    In April 1996, the Company amended its certificate of incorporation, whereby
the certificate allows for the payment of dividends to the Class B non-voting
preferred stockholders or the redemption, purchase or acquisition of the Class B
non-voting Preferred Stock without requiring declaration or payment of dividends
to any other capital stock of the Company. The amendment was retroactive to
1994.
 
11. PREFERRED STOCK:
 
    The Company has 550 shares of 15% Convertible Preferred Stock authorized,
issued and outstanding. The Preferred Stock is convertible to shares of Class A
Common Stock at a conversion rate of 1:1. The shares earn dividends at the rate
of $200.55 per share on July 15 and on January 15 of each year. These dividends
are cumulative with effect from July 15, 1990 and interest will be payable at
15% per annum on any unpaid dividends. The Convertible Preferred Stock is senior
to all other classes of capital stock with regards to capital and dividend
distributions. In the event of liquidation, dissolution or winding up of the
Company, each holder of the 15% Convertible Preferred Stock shall be entitled to
receive $2,674 per share plus all accrued and unpaid dividends and accrued
interest thereon to the date fixed for distribution out of the assets available
for distribution.
 
    In addition, the Company has authorized 9,450 shares of PIK redeemable
Preferred Stock and 1,000 shares of Class B non-voting Common Stock of which
none are outstanding as of December 31, 1997 and 1996 and September 30, 1998.
 
12. COMMITMENTS AND CONTINGENCIES:
 
    The Company and its subsidiaries are parties to lawsuits or may in the
future become parties to lawsuits involving various types of commercial claims.
Legal proceedings tend to be unpredictable and costly and may be affected by
events outside the control of the Company. The Company maintains various levels
of insurance to apply to product liability and certain other claims in excess of
deductibles. There is no assurance that litigation will not have an adverse
effect on the Company's financial position, results of operations or cash flows.

    In the third quarter of 1998, pursuant to a board resolution and subsequent
separate management stock award agreements, several senior executives of the
Company were awarded Common Stock of the Company's parent holding company and
cash in lieu of individual income taxes. The stock awards vest immediately and
the stock and cash were estimated by the Company to have a fair value of
approximately $1,091,000. Accordingly, such amount has been recorded as
compensation expense for the nine months ended September 30, 1998.
 
    The Company, through a wholly-owned subsidiary, entered into a merger
agreement, dated as of August 12, 1998, with Envirotest Systems Corp. (ESC), a
Delaware corporation, pursuant to which the Company commenced a tender offer for
all of the issued and outstanding shares of ESC's Class A Common Stock for
$266.3 million in cash, or $17.25 per share, plus the assumption of
approximately $275 million in net debt. The Class B and Class C shares of ESC's
Common Stock are convertible by the holders thereof into shares of Class A
Common Stock on a one-for-one basis and thus may be tendered as well. At
September 30, 1998, the Company has incurred approximately $2.5 million in
acquisition related costs which are deferred in the accompanying balance sheet.

    On October 8, 1998, the Company entered into an agreement with Bank of
America and BA Credit Corporation, pursuant to which a Delaware limited
liability company, ESP Financial Services LLC, ("ESP Financial") has been
established to provide financing for vehicle emissions testing equipment to be
sold by ESP to decentralized facilities. ESP Financial Services LLC is 90% owned
by ESP and 10% owned by BA Credit Corporation. After ESP has arranged a sale of
vehicle emissions testing equipment with a decentralized facility owner
operator, ESP Financial will purchase the equipment from ESP and lease it to the
facility. ESP will receive payment in full for the sale from ESP Financial at
the time of sale, ESP Financial will securitize the lease payments from the
decentralized facilities and after repayment to BA Credit Corporation and its
affiliates of the purchase price for the equipment, ESP and BA Credit
Corporation will share in the spread between the actual or implied interest
rates on the lease payments and on the instruments issued in connection with the
securitization based on their respective interests in ESP Financial.
 
    Effective October 15, 1998 the Company completed its tender offer and merger
with ESC. This business combination will be accounted for by the Company by the
purchase method. ESC had revenue of approximately $168 million for the year
ended September 30, 1998. In connection with the merger and related financing
the Company paid, among other professional fees, $5 million to Alchemy for
arranging the merger and financing.

ENVIROTEST SYSTEMS CORP. AND SUBSIDIARIES
 
    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of changes in stockholders' deficit and
of cash flows present fairly, in all material respects, the financial position
of Envirotest Systems Corp. and its subsidiaries (the "Company") at September
30, 1998 and 1997, and the results of their operations and their cash flows for
each of the three years in the period ended September 30, 1998, in conformity
with generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   ENVIROTEST SYSTEMS CORP. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATMENTS
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1.      ORGANIZATION:
 
    Envirotest Systems Corp. ("Envirotest" or the "Company") markets, installs
and operates centralized vehicle emissions testing programs under contracts
entered into with state and municipal governments within the United States and a
program in British Columbia, Canada. The Company also offers states and
municipalities services in a variety of sophisticated data management and
vehicle identification capabilities.
 
    Envirotest provides governmental authorities an all-inclusive service
whereby it designs, constructs, and operates centralized vehicle emissions
programs. The Company's services include: designing a network that provides
convenience to motorists; identifying and procuring adequate inspection sites;
constructing emissions facilities with multiple test lanes; designing and
installing a proprietary vehicle emissions inspection system and computer
network to collect and process emissions testing data; and managing and
operating the inspection program using sophisticated software and equipment
developed by the Company.
 
    On August 12, 1998, Envirotest, entered into a merger agreement with Stone
Rivet, Inc. ("Purchaser"), a Delaware corporation and wholly owned subsidiary of
Environmental Systems Products, Inc. ("Parent"), a Delaware corporation, for the
acquisition of the Company's outstanding shares of Class A Common Stock by
Purchaser at a price of $17.25 per share in cash. Under the terms of the Merger
Agreement, upon consummation of the Merger, each outstanding share of Class B
Common Stock, $.01 par value per share, and Class C Common Stock, $.01 par value
per share, of the Company will be converted into the right to receive an amount
in cash equal to the price per Share paid pursuant to the Class A Common Stock
Offer.
 
    Under the terms of the transaction, the Purchaser commenced a cash tender
offer for all outstanding shares of the Company common stock at $17.25 per
share. Effective October 15, 1998, approximately 11,963,529 shares were tendered
and were accepted by the Purchaser for payment. The acquisition was completed by
a merger of Envirotest with the Purchaser, in which the remaining Envirotest
shares were canceled and converted into the right to receive $17.25 per share in
cash. Subsequently, Envirotest became a 100% owned subsidiary of the purchaser.
In connection with the closing of the tender offer, among other actions, the
Purchaser repaid senior subordinated debt (Note 9), senior debt (Note 10), and
long term debt (Note 11), plus any accrued interest. In connection with the
merger agreement, Envirotest incurred costs of approximately $7,828 million in
connection with the merger transaction and the amount is included in the
consolidated statement of operations as of September 30, 1998 within the caption
"Merger and acquisition costs."
 
2.      SIGNIFICANT ACCOUNTING POLICIES:
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of Envirotest and
its domestic and foreign subsidiary companies. All inter-company balances and
transactions have been eliminated in consolidation.
 
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.
 
                                      F-24
<PAGE>
2.      SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
CASH, CASH EQUIVALENTS AND AVAILABLE-FOR-SALE SECURITIES
 
    The Company considers all highly liquid investments with an original
maturity of three months or less from the date of purchase to be cash
equivalents. Cash and cash equivalents are stated at cost, which approximates
market value. Included in the Company's cash and cash equivalents are
approximately $67,686 and $8,369 of commercial paper invested through registered
broker/dealers at September 30, 1998 and 1997, respectively. The Company intends
to hold these investments until maturity.
 
    Investments are classified as "available-for-sale" and have maturities
greater than three months from the date of acquisition. Investments classified
as "available-for-sale" are reported at fair value with gains and losses net of
related tax, if any, reported as a separate component of shareholders' equity.
Available-for-sale securities of $40,955 as of September 30, 1997 primarily
consisted of certificates-of-deposit and high-grade commercial paper, with
maturity dates ranging from December 1997 through May 1998.
 
CONTRACTS AND CONTRACT RECEIVABLES
 
    The Company's contract receivables primarily consist of uncollateralized
amounts due from state, municipal and foreign governments.
 
    Under most of the Company's contracts, the governmental authority has the
right, and in some cases may be obligated, to purchase the Company's program
facilities on termination of the contract, at a price generally determined by
applying specified criteria set forth in the contract. Most contracts expressly
provide for termination if the legislation authorizing the (I/M) program is
repealed or if sufficient funds for the program are not appropriated by the
relevant governmental authority. More than half of the Company's contracts also
allow the governmental authority to terminate the contract without cause, upon
giving advance written notice of not less than 30 days. The Company is also
required to post performance bonds once the contract is awarded.
 
    Under most of the Company's I/M contracts, the Company is required to pay
liquidated damages as a penalty for failure to meet specified start-up dates or
performance requirements, in many cases after a specified notice and cure
period.
 
RESTRICTED CASH
 
    Restricted cash of $18,890 and $19,567 at September 30, 1998 and 1997
respectively, primarily consisted of certificates of deposit for the Company's
financing and performance bonds related to the emissions testing contracts with
state and municipal governments. Included in restricted cash as of September 30,
1998, are $6,579, $2,369 and $1,700 required under credit agreements for the
financing of Ohio, Indiana and Wisconsin programs, respectively. Also, $2,515 in
proceeds from bonds issued by the Indiana Development Finance Authority for the
Indiana program are being held in trust pending use of the funds and $5,727 as
collateral for performance bonds and worker's compensation insurance. The
Washington debt was paid in full in December 1997, thus releasing the $600
Washington restricted cash. Included in restricted cash as of September 30, 1997
are $6,519, $2,253, $1,700 and $600 required under credit agreements for the
financing of Ohio, Indiana, Wisconsin and Washington programs, respectively.
Also, $4,253 in proceeds from bonds issued by the Indiana Development Finance
Authority for the Indiana program are being held in trust pending use of the
funds and $4,242 as collateral for performance bonds and worker's compensation
insurance.

2.      SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
PROPERTY, PLANT, EQUIPMENT AND CAPITAL LEASE
 
    Property, plant and equipment are recorded at cost. The capital lease is
recorded at the present value of the future lease principal payments.
Depreciation and amortization are provided on the straight-line method over the
estimated useful lives of the assets or lease term as follows:
 
<TABLE>
<S>                                                          <C>
Buildings and site improvements............................  30 years
Machinery and equipment....................................  2-10 years
Leasehold improvements.....................................  Lease term
</TABLE>
 
    Buildings and site improvements are depreciated on a straight-line basis
over the estimated useful life, generally 30 years. Periodically the Company
prepares an analysis to compare the estimated net book value of the buildings,
site improvements and land at the estimated completion date of individual
contracts (assuming certain renewals, if any) to the estimated residual value.
Adjustments to depreciable lives are made accordingly.
 
    It is possible, given the political, legislative and competitive environment
in which the Company operates, that the estimates discussed above could change
and may result in accelerated depreciation charges. Also, the actual values
realized on disposal could differ from the amounts used in estimating the
residual values of these properties.
 
    Interest costs relating to the acquisition and construction of major
projects are capitalized and depreciated over the estimated useful lives of the
related assets. Interest expense capitalized for the years ended September 30,
1998, 1997 and 1996 was $1,218, $103 and $981, respectively.
 
    The cost of maintenance and repairs is charged to expense in the year
incurred. Expenditures that increase the useful lives of property and equipment
are capitalized.
 
    When items are retired or disposed of, the cost and accumulated depreciation
are removed from the accounts and any gain or loss is included in income.
 
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company assesses the recoverability of its long-lived assets by
determining whether the depreciation and amortization of the asset's net book
value over its remaining life can be recovered through projected undiscounted
future cash flows.
 
INTANGIBLE ASSETS
 
    Intangible assets are stated as cost and are amortized on a straight-line
basis over their estimated useful lives as follows:
 
<TABLE>
<S>                                                          <C>
Goodwill...................................................  12 years
Government contracts.......................................  12 years
                                                             10-17
License agreement..........................................  years
                                                             15-17
Patents....................................................  years
Covenants not-to-compete...................................  12 years
Copyrights.................................................  12 years
</TABLE>
 
    It is the Company's policy to re-evaluate the estimated useful life of each
of its intangible assets on a quarterly basis and may adjust the estimated
useful life accordingly. It is possible, given the political, legislative and
competitive environment in which the Company operates, that the estimates
discussed above could change and may result in accelerated amortization charges.

2.      SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
DEFERRED DEBT ACQUISITION COSTS
 
    Costs associated with obtaining long-term debt financing have been
capitalized and are amortized over the repayment term of the related debt.
Accumulated amortization is $8,541 and $6,817 for fiscal 1998 and 1997,
respectively.
 
DEFERRED CHARGES
 
    Significant expenses incurred in bringing new emissions testing programs
into operation including staff recruitment, staff training, public information
and similar pre-operating costs are deferred and amortized over a twelve-month
period commencing with the start of program operations. Deferred charge
amortization expenses were $609, $1,124 and $4,419 for fiscal 1998, 1997 and
1996 respectively. Accumulated amortization is $7,465 and $6,457 for fiscal 1998
and 1997, respectively.
 
CONTRACT REVENUES
 
    Generally, for vehicle emissions inspection contracts, revenue is based on
the fees that are collectible for the tests performed. Where contracts provide
for up-front payments in addition to test fees per contract, the payments are
recognized as revenue over the contract term.
 
    The Company's contract revenues from major customers, which individually
account for in excess of 10% of the Company's total contract revenue, were
$30,315; $23,225; $21,945; $20,445; and $16,981 for the year ended September 30,
1998; $20,900; $20,400; $17,300; $16,800; and $14,100 for the year ended
September 30, 1997; $20,300; $18,700; $17,000; and $16,500 for the year ended
September 30, 1996. For the fiscal year ended September 30, 1998, significantly
all of the Company's contract revenues were derived from its 14 emission testing
contracts. Contracts for the Company's existing emissions contracts expire
between the years 1999 and 2008.
 
RESEARCH AND DEVELOPMENT
 
    Research and development costs are charged to operations as incurred.
Research and development expenses for the periods ended September 30, 1998, 1997
and 1996 were approximately $36, $97 and $44, respectively and are included in
general and administrative expenses.
 
INCOME TAXES
 
    Deferred tax liabilities and assets are recognized for the expected future
tax consequences of events that have been included in the financial statements
or tax returns. Deferred tax liabilities and assets are determined based on the
difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.
 
FOREIGN CURRENCY TRANSLATION
 
    The Company has determined that the functional currency of its international
subsidiary is the local currency. In accordance with Statement of Financial
Accounting Standard No. 52, "Foreign Currency Translation," the assets and
liabilities denominated in foreign currency are translated into U.S. dollars at
the current rate of exchange existing at period-end, and revenues and expenses
are translated at average monthly exchange rates. Related translation
adjustments are reported as a separate component of stockholders' equity,
whereas gains or losses resulting from foreign currency transactions are
included in results of operations.

EARNINGS (LOSS) PER SHARE
 
    Basic EPS is computed as net income (loss) divided by the weighted average
number of common shares outstanding for the year. Diluted EPS reflects the
potential dilution that could occur from common shares issuable through stock
options, warrants and other convertible securities. Common equivalent shares are
excluded from the computation of net loss per share if their effect is
anti-dilutive.
 
    The following is a reconcilliation of the numerator - net income/(loss) and
the denominator - number of shares, used in the basic and diluted EPS
calculation (amounts in thousands except per share data):

RELATED PARTY TRANSACTIONS
 
    The Company does not enter into any transaction with a related person unless
such transaction is made in good faith and is on terms, which are (i) fair and
reasonable to the Company and (ii) on an arms-length basis. Any transaction or
series of transactions with a related person with an aggregate value in excess
of a certain amount first must be approved by a special committee of the Board
as fair and reasonable and on an arms length basis; and further, for any
transaction or series of transactions with an aggregate value in excess of a
certain amount, the Company obtains a favorable opinion as to fairness from a
financial point of view from an independent financial advisor of national
reputation.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of cash and cash equivalents, other receivables and
accrued liabilities are a reasonable estimate of their fair value due to their
short-term nature. The estimated values of the Company's long-term debt are
based on interest rates at September 30, for issues with similar remaining
maturities.
 
    The estimated fair value amounts of the Company's financial instruments have
been determined by the Company, using appropriate market information and
valuation methodologies. Considerable judgment is required to develop the
estimates of fair value, therefore the estimates provided here are not
necessarily indicative of the amounts that could be realized in a current market
exchange.

<PAGE>
2.      SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    The Company calculates the fair value of financial instruments and includes
this additional information in the notes to financial statements when the fair
value is different from the book value of those financial instruments. When the
fair value is equal to the book value, no additional disclosure is made. The
Company uses quoted market prices whenever available to calculate these fair
values. When quoted market prices are not available, the Company uses standard
pricing models for various types of financial instruments, which take into
account the present value of estimated future cash flows. The effect of using
different market assumptions and/or estimation methodologies may be material to
the estimated fair value amounts.
 
RISKS AND UNCERTAINTIES
 
    The market for the Company's services is substantially dependent on state
and federal legislation and regulations mandating air pollution controls and
vehicle emissions testing. The availability of new emissions testing contracts
depends largely on the manner by which governmental authorities choose to
implement emissions testing programs to comply with governmental negotiations.
Specifically, governmental authorities may, with certain limitations, implement
decentralized or state-run programs, as opposed to centralized
contractor-operated programs. In order to build or retain its market share the
Company must continue to successfully compete for new government contracts.
 
CONCENTRATIONS OF CREDIT RISK
 
    As of September 30, 1998 and 1997, the Company's cash and cash equivalents
and short-term investments, which consist principally of demand deposits,
commercial paper and certificates of deposit, were on deposit with several
commercial banks and an investment house. Deposits in these banks may exceed the
amount of insurance, if any, provided on such deposits. The Company has not
experienced any losses on its cash or cash equivalents.
 
    The Company maintains allowances for potential credit losses and such losses
have been within management's expectations. Financial instruments that
potentially subject the Company to concentrations of credit risk principally
comprise cash and cash equivalents, available-for-sale securities, accounts
receivable and long-term debt.
 
RECLASSIFICATIONS
 
    Certain amounts in the consolidated financial statements have been
reclassified to conform with the current year's presentation. The
reclassification had no impact on previously reported net loss or stockholders'
equity.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This Statement establishes standards for reporting and displaying
comprehensive income and its components in the consolidated financial
statements. It does not, however, require a specific format for the statement,
but requires the Company to display an amount representing total comprehensive
income for the period in that financial statement. This Statement is effective
for the Company's 1999 fiscal year.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." The Statement establishes standards for
how public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises

2.      SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
to report selected information about operating segments in interim financial
reports issued to shareholders. This Statement is effective for the Company's
1998 fiscal year. The Company does not believe it currently has any separately
reportable segments.
 
    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up Activities." SOP
98-5 provides guidance on the financial reporting of start-up costs and
organization costs, which should be expensed as incurred. This SOP is effective
for the Company's 2000 fiscal year. The Company has reviewed the provisions of
this SOP and does not believe that adoption of this standard will have a
material effect upon its results of operations, financial position, or cash
flows.
 
    In March 1998, the Accounting Standards Executive Committee issued SOP 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use." SOP 98-1 provides guidance on when costs related to software
developed or obtained for internal use should be capitalized or expensed. This
SOP is effective for the Company's 1999 fiscal year. The Company has reviewed
the provisions of the SOP and does not believe adoption of this standard will
have a material effect upon its results of operations, financial position, or
cash flows.

5.      ASSETS HELD FOR SALE:
 
    Assets held for sale primarily includes property, plant and equipment at
testing sites formerly operated under the Pennsylvania program. These properties
are currently being marketed for sale.
 
    At September 30, 1998, the Company believes it has sufficient reserves for
potential losses on the sale of properties held for sale. At September 30, 1996
the estimated loss on sale of properties of $109,402, has been recognized in the
accompanying financial statements. Losses are based on management's estimates of
the amounts expected to be realized on the sale of these assets, net of disposal
costs. The amounts the Company will ultimately realize may differ materially
from the amounts assumed in arriving at the estimated loss.
 
    Assets held for sale consisted of the following at September 30, 1998 and

6.      GAIN ON PENNSYLVANIA SETTLEMENT:
 
    Legislation adopted by the Commonwealth of Pennsylvania General Assembly
directed the Pennsylvania Department of Transportation ("PennDOT") to delay
implementation of the Pennsylvania emissions testing program until March 31,
1995. On February 28, 1995, the Governor announced an indefinite suspension of
the implementation of any program until the Commonwealth receives clarification
regarding the elements of a testing program that the federal EPA would find
acceptable.
 
    On December 15, 1995, the Company entered into a General Release and
Settlement Agreement ("Agreement") with the Commonwealth of Pennsylvania that
resolves the issues related to the Company's contract with PennDOT. Under the
terms of the Agreement, the Company was paid $25,000 on December 29, 1995 and
$40,000 on July 31, 1996 and was to be paid $40,000 on each of July 1997, and
1998 plus interest at 6% from December 15, 1995. On December 11, 1996, the
Company sold its right to receive the two remaining installment payments
totaling $80,000 in principal amount under the Agreement. The Company retained
the right to receive accrued interest of approximately $1,749, which was paid in
August 1997.
 
    The transaction was effected through a sale of the Receivables Assets from
Envirotest Partners, a Pennsylvania general partnership owned by Envirotest and
ETI, to a newly formed wholly owned subsidiary of the Company, ES Funding Corp.
("Funding"). Funding, in turn, transferred the Receivables Assets to an
affiliate of a Pennsylvania bank. Funding and Envirotest Partners provided
certain representations in connection with the transaction, including
representations as to enforceability of the Agreement against the Commonwealth,
and agreed to repurchase the Receivables Assets if Envirotest Partners fails to
comply with its obligations under the Agreement.
 
    In addition, the Company will sell the assets and retain the proceeds and
the Commonwealth will pay the Company 50% of the amount by which the net
proceeds from the sale of the assets (as defined by the Agreement as amended
December 1996) are less than $55,000 up to a maximum of $11,000 plus interest at
6% from December 15, 1995. Should the net proceeds from the sale of the assets
exceed $55,000, the Company will pay the Commonwealth 75% of the amount by which
the net proceeds exceed $55,000. The Commonwealth paid the Company $11,000, plus
accrued interest of $1,734 on July 31, 1998.
 
    The Company is of the opinion that sufficient reserves have been recognized
and that, upon final disposition of properties, no additional loss will be
recognized.
 
    During fiscal 1998 and 1997, management adjusted its estimated loss expected
to be realized for claims resulting as a consequence of the Pennsylvania
contract cancellation that have been settled, resolved or are unlikely to
present future liability. The adjustment resulted in a $2,555 and $3,950 gain on
the Pennsylvania settlement in fiscal 1998 and 1997, respectively.
 
    The gain on the Pennsylvania settlement in fiscal 1996 was calculated as
follows:

12.     STOCK OPTIONS:
 
    The Company has adopted a Stock Option Plan (the "Plan") providing for the
grant of options to purchase shares of Class A Common Stock to certain employees
of the Company and its subsidiaries and to Outside Directors (as defined) on an
annual, nondiscretionary basis. The Plan provides for the grant of options
intended to qualify as Incentive Stock Options ("ISOs") as defined by Section
422 of the Internal Revenue Code and options that do not qualify as ISOs
("NQSOs"). The exercise price per share for all ISOs generally may not be less
than 100% of the fair market value on the date of grant. The exercise price per
share for NQSOs may be less than, equal to or greater than the fair market value
on the date of grant, but not less than par value, except that the exercise
price for NQSOs granted to Outside Directors shall be the fair market value on
the date of grant. Under the Plan, such options are exercisable according to a
vesting schedule pursuant to the terms of each Option Agreement. Unless earlier
terminated by the Board of Directors, the Plan will terminate in January 2003,
10 years after its effective date.
 
    In 1993, pursuant to an agreement for consulting services, a director and
principal stockholder of the Company was granted options to purchase 50,000
shares of Class A Common Stock at an exercise price of $9.75 per share and
50,000 shares at an exercise price of $14.00 per share. Options to purchase
25,000 shares of each of the foregoing options (an aggregate of 50,000) vested
upon grant, with the remaining options vesting in September 1994. The
unexercised options expire August 31, 1998. In 1997 the Company granted new
options in exchange for the surrender and cancellation of certain of its
existing Options with this director; such new Options to have a purchase price
equal to $6.125 with the other terms of such new Options to be identical to the
terms of the surrendered and cancelled Options, including the vesting schedule.
 
    In the first quarter of 1997, the Company granted non-qualified options to
purchase shares of the Class A Common Stock to certain Non-Executive Directors
of the Company at an exercise price equal to the fair market value of the
Company's Class A Common Stock on the date of grant. The options vest ratably
over three years and terminate after ten years.
 
    In the first and second quarter of fiscal year 1998, the Company granted
non-qualified options to purchase shares of the Class A Common Stock to certain
Non-Executive Directors of the Company at an exercise price equal to the fair
market value of the Company's Class A Common Stock on the date of grant. The
options vest ratably over three years and terminate after ten years.
 
    The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation." Accordingly, no compensation cost has been recognized for the
1993 Plan. Had compensation cost for the 1993 Plan been determined based on the
fair value at the grant date for options granted in fiscal 1998 and 1997

    The fair value of each option that was granted after October 1, 1995 is
estimated on the date of the grant using the Black-Scholes multiple option
pricing model with the following weighted average assumptions:

    The weighted average expected life was calculated based on the vesting
period and the exercise behavior of the employees.
 
    The weighted average fair value of options granted in 1998, 1997 and 1996
was $3.50, $2.09 and $1.38, respectively.

13.     STOCKHOLDERS' EQUITY:
 
    Envirotest Systems Corp. was incorporated on August 20, 1990 for the purpose
of purchasing Hamilton Test Systems, Inc. ("HTS"), a wholly owned subsidiary of
United Technologies Corporation (the "Prior Parent"). At the time of the HTS
acquisition, a subsidiary of the Prior Parent had an equity interest in
Envirotest of approximately 23.6% of the outstanding stock. Generally Accepted
Accounting Principles require that a portion of the equity participation in
Envirotest by the Prior Parent be valued using the carry-over basis of its
equity interest in HTS. Accordingly, a portion of HTS' assets were recorded at
the book value of the Prior Parent. The effect of the predecessor carry-over
basis of $5,578 is reflected as a component of stockholders' equity.
 
    In September, 1997, the Company purchased 4,388 shares of its Class A Common
Stock, par value $0.01 per share (the "Common Stock"), at a price of $4.50 per
share pursuant to its "Dutch" auction tender offer. All such shares were
purchased by the Company for approximately $29,003, including associated
repurchase costs. The repurchased shares are accounted for at cost, including
associated repurchase costs, and recorded as treasury stock in the accompanying
balance sheet at September 30, 1997. Cost directly related to the repurchase of
shares were $9,257 and are included as part of the cost of the shares acquired.
 
    Payment of cash dividends is restricted by the terms of the Indenture
covering the Senior and Senior Subordinated Notes (under a formula based on the
consolidated net income of the Company plus proceeds of equity offerings) and
subject to the maintenance of a certain consolidated fixed charge coverage
ratio.

15.     DEFINED CONTRIBUTION PLAN AND SUPPLEMENTAL RETIREMENT PLAN:
 
    The Company has adopted a defined contribution 401(k) plan (the "Plan")
covering substantially all its employees. Eligible employees may contribute up
to 16% of base compensation to the Plan. The Company has an optional matching
program where the Company can match 50% of the employee's first 6% of

employee's credited service to the Company. The Company also has an option to
make additional profit-sharing contributions equal to 2% of the base salary of
each Plan participant. Defined contribution expense for the Company was

from $13 to $100 per year commencing at age 65 for a period of ten years payable
in equal monthly installments. The plans also provide death and disability
benefits in the event of the death or total disability of an employee while
employed by the Company. The Company's policy is to fund the plan through
certain life insurance policies or through the

general unrestricted assets of the Company. Supplemental retirement expense for
the Company was approximately $43, $105, and $119, for the years ended September
30, 1998, 1997 and 1996, respectively.
 
16.     RELATED PARTY TRANSACTIONS:
 
    In 1993, the Company entered into a three-year agreement for consulting
services with a director and principal stockholder of the Company. The agreement
provides for a base-consulting fee of $240 plus expenses annually for the first
year and $120 annually thereafter, as well as the grant of options. For the
years ended September 30, 1998, 1997 and 1996, the Company expensed $0, $0 and
$120, respectively under this agreement.
 
    The Company retained a director of the Company to render consulting
services. The agreement originally provided for a base-consulting fee of $10 per
month plus expenses which decreased to $5 per month plus expenses in August
1997. For the year ended September 30, 1998 and 1997 the Company expensed $0 and
101, respectively, under this agreement. This agreement expired in 1998.
 
    The Company has employee agreements with five executive employees whereby
the Company is obligated to pay the employee's salary, including benefits, from
one to three years. In addition, the Company is required to pay bonuses to two
employees upon change of ownership (as defined by the agreements). Total salary
and bonuses payable to the five employees is $3.5 million. These amounts were
either paid to the employees as of the effective date of the merger or will be
paid in the form of a monthly annuity over a one to three year period.
 
    As the Company has previously disclosed in its periodic reports filed with
the Securities and Exchange Commission under the Securities and Exchange Act of
1934, the facilities and assets used by the Company in the Cuyahoga County, Ohio
I/M testing program (the "Ohio Assets") and the Tennessee I/M testing program
(the "Tennessee Assets") were leased to the Company pursuant to separate Sale
and Leaseback Agreements with Kane Partners, L.P. ("Kane Partners"). Richard
Gelfond, a director of the Company, is Vice President of the General Partners of
Kane Partners and holds a 25% limited partnership interest in Kane Partners.
Chester C. Davenport, Chairman of the Company, holds a 25% limited partnership
interest in Kane Partners. In November 1992, Kane Partners acquired the
underlying leasehold property and the related rights and obligations from the
original lessors of the Ohio and Tennessee Assets.
 
    The statute and regulations governing Ohio's new I/M240 test program require
that the land and buildings be owned by a third party having no affiliation with
the operator of the program. The Ohio program is divided into four separate
zones, three of which were subject to competitive bid and, when awarded,
complied with this requirement. The fourth zone, Cuyahoga County, was subject to
an existing contract held by Envirotest at the time contracts for the other
zones were awarded by the State (two of which were awarded to the Company). As a
condition to entering into a new 10 year contract with Envirotest to conduct
I/M240 vehicle inspections in Cuyahoga County, Ohio (and not submitting this
zone to a competitive bid), the State of Ohio required Envirotest to comply with
its new I/M legislation and caused Kane Partners to divest its ownership
interest in the Ohio Assets. Accordingly, the third party developer utilized
approximately $10,000 of the net proceeds of the Authority offering described in
Note 17 to acquire ownership of the Ohio Assets that will be used in the new
Cuyahoga County, Ohio program to be operated by the Company. As a result, the
land and buildings used by the Company under its three Ohio I/M240 program
contracts will be owned by the developer and leased to the Company.
 
    In connection with the negotiations related to the Ohio Assets, the Company
agreed to purchase from Kane Partners the Tennessee Assets for $1,800 and one
Ohio test site that will not be used in the new test program for $300, for an
aggregate purchase price of $2,100. Although Tennessee Assets and Ohio Assets

16.     RELATED PARTY TRANSACTIONS: (CONTINUED)
have been subject to separate sale and leaseback agreements, the assets have
served as functional security for a financing provided to the Company in 1990
and were held by Kane Partners since 1992 for the same purpose. Kane Partners
utilized a portion of the aggregate proceeds received by it from the sale of the
Ohio Assets and Tennessee Assets to retire certain debt obligations held by
Chemical Venture Partners and Apollo Advisors, L.P., affiliates of which are
directors of the Company and beneficially own approximately 14% and 17%,
respectively, of the Company's outstanding Class A Common Stock. These debt
obligations were incurred by Kane Partners in connection with its initial
acquisition of the Ohio Assets and Tennessee Assets.
 
    In connection with the evaluation and approval of the acquisition of the
Ohio Assets and the Tennessee Assets, and as required by the Senior Notes debt
covenants, a committee of disinterested directors of the Company retained an
independent financial advisor which rendered an opinion stating that (i) the
purchase price paid for the Ohio Assets and Tennessee Assets (collectively, the
"Purchase Price") was fair to the public shareholders of the Company from a
financial point of view, and (ii) the Purchase Price was fair and reasonable to
the Company from a financial point of view and was on financial terms at least
as favorable as financial terms that could be obtained by the Company in a
comparable transaction made on an arm's length basis with persons who are not
related persons.
 
17.     CAPITAL LEASE AND LONG-TERM DEBT OBLIGATION:
 
    On June 30, 1995, the Ohio Air Quality Development Authority (Authority)
issued $64,380 of bonds with an 8.1% interest rate to finance the costs of the
acquisition, construction, renovation and equipping of the Company's emissions
testing network in Ohio. The bonds are subject to mandatory sinking fund
redemption and are due December 31, 2005. The land and buildings are owned by a
developer (the "Developer") and leased to the Company pursuant to a capital
lease. The equipment is owned by the Company. The Developer and the Company
separately have entered into loan agreements with the Authority under which the
payments will provide for timely payment of principal and interest on the bonds.
The Developer and the Company have entered into a master lease agreement
pursuant to which the developer will lease the land and buildings to the
Company. The proceeds are held in trust pending use of the funds and the
unexpended proceeds are reflected on the Company's balance sheet as restricted
cash.
 
    Pursuant to the master lease and loan agreements, all revenues from the
operation of the Ohio emissions testing network are paid into certain accounts
held by the Trustee pursuant to a cash management services agreement. The excess
of revenues from operations over the amount required to be paid monthly to the
Authority under the loan agreements and to the Ohio Environmental Protection
Agency per the contracts will be available to the Company. The bonds are
collateralized by all Ohio program assets.

18.     OPERATING LEASES:
 
    The Company is obligated under noncancelable operating leases for the
building sites in Vancouver, British Columbia. The Vancouver lease runs for
seven years ending August 31, 1999, with monthly payments averaging
approximately $300. The Company has the option to renew this lease for an
additional seven-year period.
 
    As of September 30, 1998, approximate future minimum lease commitments under
noncancelable operating leases are as follows:

    Rental expense for the years ended September 30, 1998, 1997 and 1996 was
approximately $5,760, $6,043 and $4,112 respectively, net of sublease income of
approximately $185, $429 and $289 for 1998, 1997 and 1996 respectively.
 
19.     EXTRAORDINARY LOSS:
 
    During fiscal 1997, the Company recognized an extraordinary loss from the
write-off of amortization of deferred issuance costs, original issue discounts
and tender offer fees of $1,324, in connection with the repurchase of $50,000
aggregate principal amount of its 9 1/8% Senior Notes due 2001, completed
September 17, 1997.
 
20.     COMMITMENTS AND CONTINGENCIES:
 
    The Company has several performance bonds on its long-term contracts. These
bonds are required by the contracts and vendor agreements in the event the
Company cannot perform and complete the
 
                                      F-42
<PAGE>

contracts and agreements. In addition, a bank holds a letter of credit in the
amount of $2,400 guaranteed by the Company in connection with its performance
obligations in respect to the Washington State contract. In the opinion of
management, the Company will be able to fulfill the requirements of the
long-term contracts and leases. In June 1997, the Company signed an agreement
with the State of Illinois to upgrade the State's existing centralized auto
emissions testing program to an enhanced program. The agreement also extends the
program term to 2006. Capital expenditures required to implement the new program
are expected to total approximately $75,000. Enhanced testing will commence in
early 1999.
 
    On August 29, 1997, the Company purchased from Hughes Aircraft Company
("Hughes") the assets comprising Hughes' remote emissions sensing product line
and related technologies for $3,700. In addition, the Company agreed to pay a 3%
royalty on future net revenues related to remote sensing sales and services over
the next five years up to a cap of $10.0 million. The royalty payments are
contingent on future revenues from remote sensing sales and services and totaled
$55 as of September 30, 1998. The Company also assumed Hughes' contract with the
State of Arizona to provide remote sensing services. The acquisition has been
accounted for as a purchase. The impact on the 1997 financial statements was not
material.
 
    The Company and its subsidiaries are parties to lawsuits or may in the
future become parties to lawsuits involving various types of commercial claims,
including, but not limited to, breach of contract and intellectual property
matters. Legal proceedings tend to be unpredictable and costly and may be
affected by events outside the control of the Company. There is no assurance
that litigation will not have an adverse effect on the Company's financial
position, results of operations, or cash flows.
 
    State of Connecticut v. Envirotest Systems Corp. Under the new contract
entered into with the Company in April 1994, the State unilaterally decided to
continue the old testing procedure and phase in the enhanced testing required by
the new contract. Additionally, the Company was unable to build two test
facilities, one due to the State's inability to provide the land the contract
required and the other due to the inability to obtain zoning. As a result, the
Company and the State of Connecticut were in dispute concerning various
financial issues related to the performance by each of their respective
obligations under the Contract. On May 8, 1998, the Company and the State of
Connecticut entered into an agreement (the "Agreement") settling the State's
claims against the Company, except for certain penalties unrelated to the
settled claims which the parties are to negotiate, and the Company's claims
against the State. The Agreement modifies the terms of the Company's existing
vehicle inspection and safety inspection contracts with the State to provide
among other things, for the Company to add five emissions inspection lanes to
its existing network in lieu of constructing an additional station as required
under the existing contracts.
 
    Ganzcorp Investments, Inc. v. Envirotest Systems Corp. On September 26, 1995
Ganzcorp Investments, Inc. d/b/a/ Mustang Dynamometer filed suit against
Envirotest Systems Corp. in U.S. District Court for the Northern District of
Ohio. The suit alleged breach of contract and asked for damages in excess of
$10.0 million. The suit was voluntarily dismissed by the parties on December 22,
1995 so that the parties could focus on settlement negotiations. On October 8,
1997, the case was re-filed by Ganzcorp when settlement negotiations broke down
between the parties. In 1993, the parties signed an agreement for the supply of
chassis dynamometers by Ganzcorp to the Company for its emission testing
programs in Ohio, Connecticut, and Pennsylvania. When the Company's testing
program with the State of Pennsylvania was canceled, the Company canceled its
contract with Ganzcorp per a "termination for convenience" clause. Under such
clause Ganzcorp would be allowed to make a claim for certain costs incurred but
such a claim would be substantially below its stated claim of more than $10,000.
Additionally, the Company has counterclaims against Ganzcorp for breach of
contract and warranty obligations which it believes to be in excess of $7,900.
Subsequent to September 30, 1998, the Company has agreed in principal to pay
Ganzorp up to $1.5 million in settlement of all of the above claims. The
settlement amount has been included in the

accompanying financial statements within the balance sheet caption "accrued
expenses and other current liabilities."
 
    R.W. Granger & Sons filed a Demand for Arbitration in the East Hartford,
Connecticut, office of the American Arbitration Association in September 1996
alleging breach of contract and failure to pay amounts due Granger in connection
with the construction of certain of the Company's testing facilities in the
State of Connecticut. On December 29, 1997, Granger filed a complaint in State
Superior Court in the Judicial District of Hartford/New Britain at New Britain
alleging that the Company's failure to pay amounts due to Granger is an unfair
trade practice under the Connecticut Unfair Trade Practices Act. The Arbitrators
awarded Granger approximately $495, including the costs of the Arbitration, in a
decision rendered on August 12, 1998. Granger was claiming damages of
approximately $2.0 million in its Demand for Arbitration. Granger has moved to
modify the arbitration award seeking additional alleged damages of approximately
$200,000, which motion is pending. The Company intends to vigorously defend
against Granger's remaining claim in State Superior Court and the Company
believes that any judgment against the Company with respect to the remaining
claim will not have a material adverse effect on its financial position and
results of operations.
 
    Timothy J. Grendell, et al v. Ohio Environmental Protection Agency, et al.
On November 18, 1998, Timothy J. Grendell, on behalf of himself and all others
similarly situated, filed a class action lawsuit in the Court of Common Pleas,
Summit County, Akron, Ohio. The defendants include the Ohio Environmental
Protection Agency and the Company. Grendell filed a virtually identical suit in
1996 and it was dismissed without prejudice exactly one year before the
above-noted class action lawsuit was filed. Like the 1996 lawsuit, the
above-noted class action lawsuit asserts that the statute and contract that
created E-Check are unconstitutional under Ohio law, and requests declaratory
and injunctive relief, attorney fees and costs. The Company believes that it has
valid defenses to the claims contained in the complaint and intends to defend
the matter vigorously.
 
    In addition to the above, the Company is a party to various other legal
proceedings and claims in the ordinary course of business. Although the claims
cannot be estimated, in the opinion of management the resolution of these
matters will not have a material adverse effect on the Company's consolidated
financial position and results of operations.
 
21.     FOREIGN OPERATIONS:
 
    The Company's contract revenues from its foreign subsidiary, located in
Vancouver, British Columbia, Canada, were approximately $13,475, $14,062 and
$10,147 for the years ended September 30, 1998, 1997 and 1996, respectively, and
were earned from a single customer. Identifiable assets of the foreign
subsidiary totaled approximately $5,019, $4,786, and $6,913 at September 30,
1998, 1997 and 1996, respectively. The foreign subsidiary had a gross profit
before selling, general and administrative expenses of approximately $3,715,
$3,173 and $572 for the years ended September 30, 1998, 1997 and 1996,
respectively.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The information below briefly outlines the provisions of Section 102(b)(7)
of the General Corporation Law of the State of Delaware, Article X of our
Certificate of Incorporation and Article VIII of our By-Laws. For more
information, you may review the provisions of our Certificate of Incorporation
and By-Laws that we filed with the SEC.
 
    ELIMINATION OF LIABILITY
 
    Section 102(b)(7) of Delaware's corporation law gives each Delaware
corporation the power to eliminate or limit its directors' personal liability to
the corporation or its stockholders for monetary damages for certain breaches of
fiduciary duty as a director, except:
 
    - for any breach of the director's duty of loyalty to the corporation or its
      stockholders;
 
    - for acts or omissions in bad faith, or involving intentional misconduct or
      a knowing violation of the law;
 
    - under Section 174 of Delaware's corporation law (providing for liability
      of directors for the unlawful payment of dividends or unlawful stock
      purchases or redemptions); or
 
    - for any transaction from which a director derived an improper personal
      benefit.
 
    You should know that our Certificate of Incorporation eliminates the
personal liability of our directors to the fullest extent permitted by Section
102(b)(7) of Delaware's corporation law.
 
    INDEMNIFICATION
 
    Section 145 of Delaware's corporation law grants each Delaware corporation
the power to indemnify its directors and officers against liability for certain
of their acts.
 
    Our By-Laws provide, among other things, that under certain circumstances we
are required or permitted to indemnify any officer or director of our company
(or such person's estate):
 
    - who was or is a party (or is threatened to be made a party) to a
      threatened, pending or completed action, suit or other proceeding;
 
    - whether or not the action, suit or other proceeding was or is in the right
      of our company;
 
                                      II-1
<PAGE>
    - regardless of whether the suit or other proceeding was or is civil,
      criminal, administrative or investigative in nature; and
 
    - by reason of the fact that he or she is or was one of our directors or
      officers, or is or was serving at our request as a director or officer of
      another corporation, partnership or other enterprise.
 
    Unless otherwise permitted by applicable laws, our By-Laws require us to
make a case-specific determination, in accordance with applicable laws, that
indemnification is proper in the circumstances. Our by-laws only require us to
indemnify an officer or director if he or she acted in good faith and in a
manner he or she reasonably believed to be consistent with our best interests.
Moreover, with respect to any criminal action or proceeding, one of our officers
or directors is only entitled to indemnification if he or she had no reasonable
cause to believe his or her conduct was unlawful. We are not required to
indemnify, or advance expenses to any person in connection with any action, suit
or other proceeding (including any counterclaim) initiated by or on his or her
behalf.
 
    You should know, however, that in the event that an officer or director of
our company is entitled to indemnification under our By-Laws, we may be required
to indemnify him or her against expenses (including, for example, attorneys'
fees, judgments, penalties, fines and settlement amounts actually and reasonably
incurred and not recovered related to such officer or director's investigation,
preparation to defend or defense of such action, suit, or other proceeding). You
should also know that, to the extent permitted by our By-Laws, our By-Laws
authorize us to pay any such expenses in advance of the final disposition of the
action, suit or other proceeding in question. Our By-Laws also authorize us to
make, to the extent permitted by law, such advance payments even if the officer
or director in question is alleged to have failed to meet the "good faith"
standard of conduct discussed above, or is alleged to have committed conduct
which, if true, would avail us from indemnifying such officer or director.
Before making any advance payment, our By-Laws require us to receive an
undertaking by or on behalf of the director or officer in question to repay the
advance if it is ultimately determined that he or she is not entitled to
indemnification.

ITEM 22. UNDERTAKINGS.
 
    The undersigned Registrants hereby undertake:
 
    (1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
        (i) to include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
        (ii) to reflect in the prospectus any facts or events arising after the
    effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    registration statement. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total dollar value of
    securities offered would not exceed that which was registered) and any
    deviation from the low or high end of the estimated maximum offering range
    may be reflected in the form of prospectus filed with the Commission
    pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement; and
 
        (iii) to include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or any
    material change to such information in the registration statement;
 
    (2) that, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof;
 
    (3) to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering;
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the Registrants
have been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for
 
                                      II-8
<PAGE>
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrants will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

with respect to the purchase of its securities described in Section 1.1 below:

          1.   ISSUANCE OF NOTES AND SERIES A SHARES.

          1.1  THE NOTES AND SHARES.  The Company has authorized the issuance
pursuant to this Agreement of $100,000,000 aggregate principal amount of the
Company's 13% Senior Subordinated Notes due 2008 (the "Notes") to be issued
under and entitled to the benefits of an Indenture to be substantially in the

together with the Company and the Parent, the "Issuers").  The  Notes and the
Series A Shares will be issued on the Closing Date (as defined in Article 2
hereof).  For purposes of this Agreement, (i) the term "Securities" means the
Notes, together with the guarantees thereof by the Guarantors, and the Series A
Shares and (ii) references to "Subsidiaries" or "subsidiaries" of the Parent or
the Company shall mean all subsidiaries of the Parent or the Company, including

indirect subsidiaries of ESP.

          1.2  THE PURCHASERS.  The purchase of all of the Notes and Series A
Shares is as provided for in this Agreement.

          Each of the Purchasers agrees to purchase, separately and severally,
the principal amount of Notes and the number of Series A Shares set forth below
its name on the signature pages hereto. The Purchasers shall not be obligated to
buy any of the Notes or the Series A Shares unless the Parent and the Company
shall have observed, performed, or otherwise complied with the conditions set
forth in Article 5 hereof.

          2.   CLOSING.  The closing (the "Closing") of the transactions
contemplated by this Agreement shall take place as follows:

          2.1  SALE AND PURCHASE OF THE NOTES AND SHARES.  On the basis of the
representations and warranties contained or incorporated by reference herein,
(i) the Company will sell to the Purchasers, and the Purchasers will purchase
from the Company, at the Closing on October 16, 1998, or such later date as may
be agreed upon in writing by the Company, the Parent and the Purchasers (the
"Closing Date"), the aggregate principal amount of Notes set forth below the
respective names of the Purchasers on the signature pages hereto and (ii) the
Parent will sell to the Purchasers, and the Purchasers will purchase from the
Parent, on the Closing Date, the number of Series A Shares set forth below the
respective names of the Purchasers on the signature pages hereto.  The purchase
price for the Notes and the number of Series A Shares set forth below the name
of each Purchaser on the signature pages hereto is the aggregate purchase price
for the Notes and the number of Series A Shares to be purchased by each
respective Purchaser.

          At the Closing, the Company will deliver, against payment of the
purchase price therefor, the Notes, in the form of one or more permanent global
securities in definitive form (the "Global Securities") deposited with the
Trustee as custodian for The Depository Trust Company ("DTC") and registered in
the name of Cede & Co., as nominee for DTC.  Interests in any permanent Global
Securities will be held only in book-entry form through DTC, except in the
limited circumstances described in the Offering Memorandum (as defined).  The
Notes shall be dated the Closing Date, and shall be in the aggregate principal
amount to be purchased by the  Purchasers.  On the Closing Date, the Parent will
deliver stock certificates representing the Series A Shares to be purchased by
each Purchaser to such Purchaser or to


                                          2
<PAGE>

such Purchaser's nominee or other designee (designated in writing to the Company
or the Parent, as applicable, at least one day prior to the Closing if different
from any such nominee or designee specified on the signature pages hereto, and
each hereinafter referred to as a "Designee"), against payment of the purchase
price therefor in immediately available funds.  The Parent and the Company agree
that Credit Suisse First Boston Corporation, which is acting as placement agent
in connection with the placement of the Notes and the Series A Shares (in such
capacity, the "Placement Agent"), may, in its discretion, deduct from the
purchase price of the Notes and the Series A Shares to be remitted to the
Company or the Parent at the Closing the amount of its agreed fees as Placement
Agent.  The Closing will take place at the office of Skadden, Arps, Slate,
Meagher & Flom LLP, 919 Third Avenue, New York, New York 10022, at 9:00 a.m.,
New York time, on the Closing Date.

          On the Closing Date, the Company, the Parent and the Purchasers shall
enter into a Registration Rights Agreement to be substantially in the form of
Exhibit B hereto with respect to the Notes (the "Registration Rights Agreement")
and the Parent, Alchemy Partners (Guernsey) Limited, the Purchasers and the
other securityholders therein shall enter into an Investors Agreement to be
substantially in the form of Exhibit C hereto with respect to the Series A
Shares (the "Investors Agreement") providing for the registration of the
Securities under the Securities Act of 1933, as amended (the "Securities Act").

          2.2  NATURE OF OBLIGATIONS.  The obligations of each Purchaser
hereunder are several and not joint and it is explicitly acknowledged by each
party hereto that no Purchaser is entering into any transaction for the purchase
of the  Notes or the Series A Shares or any other securities of the Issuers
jointly with any other person, firm or corporation.

          2.3  FAILURE TO CLOSE.  Notwithstanding anything to the contrary in
this Agreement, if the Closing fails to occur on or before October 27, 1998 each
party hereto shall, at its election, be relieved of all further obligations
under this Agreement (unless the Closing failed to occur due to a default by
such party in its obligations hereunder) without thereby waiving any rights it
may have by reason of such nonfulfillment or failure.

Series A Shares harmless against any and all liabilities with respect to all
such taxes.  Neither the Company nor the Parent will be responsible for any
transfer taxes in connection with transfers of the Notes or Series A Shares by
the Purchasers and any other holder of Notes or Series A Shares.  The
obligations of the Company and the Parent under this paragraph (b) shall survive
the payment, prepayment, redemption or repurchase of all such Notes and Series A
Shares and the termination of this Agreement.

               (c)  PUBLIC DISCLOSURES.  The Parent and the Company will take
all reasonable actions necessary to keep each Purchaser's identity confidential
and will not disclose each Purchaser's identity as an investor in the Parent or
the Company in any public announcement, governmental filing or otherwise without
each such Purchaser's prior written consent unless such disclosure is required
by law, rule, regulation or by order of a court of competent jurisdiction or by
any governmental agency.  If such disclosure is so required, the Parent or the
Company will give written notice to each such Purchaser describing in reasonable
detail the proposed content of such disclosure and will afford each such
Purchaser an opportunity to suggest modifications in the form and substance of
such proposed disclosure prior to making such disclosure.  Notwithstanding the
foregoing, if the Parent or the Company files a registration statement pursuant
to the Registration Rights Agreement, the Parent or the Company, as the case may
be, may make all required disclosures under the Securities Act, including but
not limited to, the disclosure of the names of the beneficial owners of the
Notes or Series A Shares and the number of  Notes or Series A Shares held by
such owner.

<PAGE>

The purchase of and any payment for the Notes and the Series A Shares to be
purchased by such Purchaser hereunder is not prohibited by any law or
governmental regulation applicable to such Purchaser, shall not subject such
Purchaser to any penalty or, in the reasonable judgment of such Purchaser, other
onerous condition under or pursuant to any applicable law or governmental
regulation, and is permitted by the laws and regulations of the jurisdictions to
which such Purchaser is subject.

          4.3  INVESTMENT BY ERISA PLANS. (a) Each of the Purchasers represent
that at least one of the following is accurate as to each source of funds to be
used by it to purchase the Securities:

               (i)  it is not acquiring the Securities with the assets of any
     employee benefit plan which is subject to Title I of the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA") or any "plan"
     which is subject to Section 4975 of the Internal Revenue Code of 1986, as
     amended (the "Code") (each such employee benefit plan and plan being
     referred to herein as a "Benefit Plan");

               (ii)  the source of funds being used to acquire the Securities is
     either (A) an insurance company pooled separate account, within the meaning
     of Department of Labor Prohibited Transaction Class Exemption ("PTCE") 90-1
     (issued January 29, 1990), or (B) a bank collective investment fund, within
     the meaning of PTCE 91-38 (issued July 12, 1991) and the purchase and
     holding of such Securities is exempt under either PTCE 90-1 or PTCE 91-38;

               (iii)  the Purchaser is an insurance company and the source of
     funds being used by such Purchaser to acquire the Securities is an
     "insurance company general account," as such term is defined in PTCE 95-60
     (issued July 12, 1995), and such acquisition and holding of the Securities
     is exempt under PTCE 95-60;

               (iv)  the source of funds being used by such Purchaser to acquire
     the Securities constitute plan assets that are included in an "investment
     fund" (within the meaning of Part V of PTCE 84-14 (issued March 13, 1994)
     (the "QPAM Exemption") managed by a "qualified professional asset manager"
     or "QPAM" (within the meaning of Part V of the QPAM Exemption)), which
     assets when combined with the assets of all other employee benefit plans
     established or maintained by the same employer or by an affiliate (within
     the meaning of Section V(c)(1) of the QPAM Exemption) of such


                                          7
<PAGE>

     employer or by the same employee organization and managed by such QPAM, do
     not exceed 20% of the total client assets managed by such QPAM, the
     conditions of Part I(c) and (g) of the QPAM Exemption are satisfied,
     neither the QPAM nor a person controlling or controlled by the QPAM
     (applying the definition of "control" in Section V(e) of the QPAM
     Exemption) owns a 5% or more interest in the Company and the acquisition
     and holding of such Securities is exempt under PTCE 84-14; or

               (v)  another exemption from the prohibited transaction rules
     applies such that the use of funds to acquire the Securities does not
     constitute a non-exempt prohibited transaction in violation of Section 406
     of ERISA or Section 4975 of the Code, which could be subject to a civil
     penalty assessed pursuant to Section 502 of ERISA or a tax imposed under
     Section 4975 of the Code.

               (b)  Each Purchaser, and each subsequent holder of the
Securities, covenants that it will not dispose of the Securities to be acquired
by it or any interest therein (including, without limitation, any transfer by a
change in the capacity in which such Purchaser holds its investment in such
Securities) to any person unless such person shall (i) make all warranties and
representations of such Purchaser contained in Section 4.3(a) and (ii) assume
all covenants of such Purchaser contained in this Section 4.3(b).

          5.   CONDITIONS OF PURCHASERS' OBLIGATIONS.  The Purchasers' several
obligations to purchase and pay for the Notes and the Series A Shares to be
purchased by them hereunder are subject to the accuracy of the representations
and warranties on the part of the Issuers contained or incorporated by reference
herein, to the accuracy of the officers' certificates of the Issuers made
pursuant to the provisions hereof and the Placement Agreement, to the
performance by the Issuers on or prior to the Closing Date of their respective
obligations hereunder or incorporated by reference herein and to the
satisfaction on or prior to the Closing Date of the conditions set forth in
Section 6 of the Placement Agreement, and each Purchaser shall be entitled to
receive all letters, opinions, and certificates that the Placement Agent is
entitled to receive pursuant to Section 6 of the Placement Agreement. To the
extent that any such representations, warranties, officers' certificates or
conditions permit any person or persons to waive compliance with such
representations, warranties, officers' certificates or conditions, or require
that a document, opinion or other instrument or any event or condition be
acceptable or satisfactory to any person or persons, for purposes of this
Agreement, such representations, warranties, officers' certificates or
conditions shall be complied with only if waived by the Purchasers and


                                          8
<PAGE>

such document, opinion or other instrument and such events or conditions shall
be acceptable or satisfactory for purposes of this Agreement only if acceptable
or satisfactory to the Purchasers.  No amendment to or waiver of such
representations, warranties, officers' certificates or conditions made pursuant
to the Placement Agreement shall be effective for purposes of this Agreement to
amend or waive such representations, warranties, officers' certificates or
conditions as incorporated by reference herein without the consent of the
Purchasers.  Notwithstanding the foregoing, no Purchaser shall be obligated to
purchase and pay for the Notes and the Series A Shares unless all the Notes and
Series A Shares are sold hereunder.

          6.   COVENANTS.  

               (a)  Each of the Issuers covenants and agrees with each of the
Purchasers and to their benefit to comply with all agreements set forth in
Section 5 of the Placement Agreement, which agreements as well as the related
defined terms are hereby incorporated by reference herein with the same effect
as if each such agreement was set forth herein in its entirety.  To the extent
that any such agreement permits any person or persons to waive compliance with
such agreement or requires that a document, opinion or other instrument or any
event or condition be acceptable or satisfactory to any person or persons, for
purposes of this Agreement, such agreement shall be complied with only if it is
waived by the Purchasers and such document, opinion or other instrument and such
event or condition shall be acceptable or satisfactory for purposes of this
Agreement only if it is acceptable or satisfactory to the Purchasers.  No
amendment to or waiver of such agreements or defined terms made pursuant to the
Placement Agreement shall be effective for purposes of this Agreement to amend
or waive such agreements and defined terms as incorporated by reference herein
without the consent of the Purchasers.

               (b)  From the date hereof until the Closing Date, each of the
Issuers covenants and agrees that it shall not enter into (or commit to enter
into) any amendment, modification or waiver of any provision of any of the
Transaction Documents without the prior written consent of the Purchasers;
PROVIDED that, in the case of any amendment, modification or waiver of the
Merger Agreement, such consent shall not be unreasonably withheld.

               (c)  From the date hereof until the Closing Date, each of the
Issuers (i) will give the Purchasers and their representatives full access to
its offices, properties, books and records, (ii) will furnish to the Purchasers
and their representatives such financial, operating and other information as
such Persons may reasonably request and (iii) will instruct its officers,
employees, counsel and auditors


                                          9

to cooperate with the Purchasers in their investigation of the Issuers.

          7.   RESTRICTIONS ON TRANSFER; THE SECURITIES ACT OF 1933.

          7.1  RESTRICTIVE LEGENDS.  The Securities shall not be transferable
except upon the conditions specified in this Article 7 and, with respect to the
Notes, the restrictions contained in Section 4.1 and the Indenture, which
conditions are intended to insure compliance with the provisions of the
Securities Act in respect of the transfer of any such Securities and, with
respect to the Series A Shares, upon the conditions specified in Article 3 of
the Investors Agreement and in the Share Price Adjustment Agreement.

          Each Purchaser and each Designee hereby acknowledges and agrees that
it is acquiring the Securities in a transaction exempt from registration under
the Securities Act and that no Security may be offered, sold, pledged or
otherwise transferred in the absence of registration under the Securities Act or
an applicable exemption therefrom.  Each of the Securities shall (unless
otherwise permitted by the provisions of this Article 7) be stamped or otherwise
imprinted with a legend in substantially the following form:

          "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR
     SOLD IN THE ABSENCE OF REGISTRATION THEREUNDER OR AN APPLICABLE EXEMPTION
     THEREFROM."

          In addition to any other legend that may be required, each certificate
for the Notes shall be stamped or otherwise imprinted with a legend in
substantially the following form:

     "THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE ISSUER THAT (A) THIS
     NOTE MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (i) INSIDE
     THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
     "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
     SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A,
     (ii) OUTSIDE THE UNITED STATES IN A TRANSACTION IN ACCORDANCE WITH RULE 904
     UNDER THE SECURITIES ACT, (iii) PURSUANT TO AN EXEMPTION FROM REGISTRATION
     UNDER THE SECURITIES ACT


                                          10
<PAGE>

     PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (iv) PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES
     (i) THROUGH (iv) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY
     STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT
     HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE
     RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE."

          In addition to any other legend that may be required, each certificate
for Series A Shares shall be stamped or otherwise imprinted with a legend in
substantially the following form:

          "THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER
     AS SET FORTH IN THE INVESTORS AGREEMENT DATED AS OF OCTOBER 16, 1998, AS
     AMENDED FROM TIME TO TIME, COPIES OF WHICH MAY BE OBTAINED UPON REQUEST
     FROM ENVIROSYSTEMS CORP. AND ANY SUCCESSOR THERETO."

          7.2  NON-APPLICABILITY OF TRANSFER RESTRICTIONS; REMOVAL OF LEGENDS. 
The restrictions imposed by Section 7.1 above upon the transferability of any
Series A Share represented by a certificate bearing the restrictive legends set
forth in such Section 7.1 (a "Restricted Security") shall cease and terminate
when such Restricted Security has been sold pursuant to an effective
registration statement under the Securities Act or transferred pursuant to Rule
144 (or any similar or successor rule thereto) promulgated under the Securities
Act unless the holder thereof is an affiliate of the Parent.  The holder of any
Restricted Security as to which such restrictions shall have terminated shall be
entitled to receive from the Parent, without expense, a new security of the same
type but not bearing the restrictive legend set forth above and not containing
any other reference to the restrictions imposed by Section 7.1 above, PROVIDED
that a holder's right to receive, and the Parent's obligation to issue, a new
Security not bearing such restrictive legends and not containing any other
reference to the restrictions imposed by Section 7.1 above shall be subject, in
the Parent's discretion, to the delivery to the Parent of an opinion of counsel
of the transferor (which may include in-house counsel to any Purchaser) that
subsequent transfers of such Restricted Security by the proposed transferee will
not require registration under the Securities Act.  As used in this Section 7.2,
the term "transfer" encompasses any sale, transfer, pledge or other disposition
of any Securities referred to herein.


                                          11
<PAGE>

          8.   EXPENSES, ETC.  

               (a)  The Company or the Parent agrees to reimburse the Purchasers
for all reasonable out-of-pocket expenses (including without limitation the
reasonable fees and expenses of one counsel for each Purchaser) of the
Purchasers incurred in connection with the Transactions, unless this Agreement
is terminated prior to the consummation of the Transactions as a result of a
breach of this Agreement by the Purchasers.

               (b)  Subject to the provisions of the next sentence of this
Article 8, each of the Company and the Parent agrees to pay, and hold the
Purchasers harmless against liability for the payment of, all stamp and other
similar taxes (together in each case with interest and penalties, if any) which
may be payable in respect of the execution and delivery of this Agreement, the
Indenture, the Investors Agreement  and the Registration Rights Agreement, if
any, or the issuance, delivery or acquisition by the Purchasers of any Notes or
Series A Shares pursuant to this Agreement and the Indenture, other than any
transfer taxes applicable to any transfer between a Purchaser and a subsequent
holder of the Notes or Series A Shares (other than the Company or the Parent),
and reasonable fees and expenses incurred by each Purchaser in connection with
any filing by the Company or the Parent with any governmental agency with
respect to the Company or the Parent that mentions such Purchaser.  Each of the
Company and the Parent additionally agrees to pay, and hold each Purchaser
harmless against liability for the payment of, all out-of-pocket expenses with
respect to the enforcement by such Purchaser of any provision of any agreement
or instrument referred to in this Article 8 plus the Registration Rights
Agreement and the Investors Agreement and any proposed amendments or waivers
(whether or not the same shall be signed or become effective) under or in
respect of any such agreement or instrument, PROVIDED that in each case the
Company or the Parent has been or, without such amendment or waiver, would be in
default in respect of its obligations thereunder.  

               (c)  The obligations of the Company and the Parent in this
Article 8 shall be of full force and effect whether or not any Notes or Series A
Shares are sold hereunder (unless the failure of any Notes or Series A to be
sold hereunder is due to a breach of, or default under, this Agreement by a
Purchaser or Designee) or the Closing ever takes place and such obligations
shall also survive the payment for or transfer of any of the Notes or Series A
Shares, the enforcement of any provisions of any agreement or instrument
referred to in this Article 8 and any amendments or waivers with respect
thereto.

          9.   INDEMNIFICATION OF PURCHASERS.  In addition to all other sums due
hereunder or provided for in this Agreement, each of the Issuers, jointly and
severally, will indemnify and hold harmless each Purchaser (which term for
purposes of this Article 9 includes any agent of or any person controlling each
such Purchaser) from and against any losses, claims, damages, liabilities, costs
and expenses (including reasonable attorneys' fees) incurred by it pursuant to
any investigation or proceeding instigated or brought by any governmental or
administrative entity or other person against the Parent, the Company or such
Purchaser arising out of or in connection with this Agreement (including the
Offering Memorandum or any other document or instrument delivered in connection
herewith), except to the extent that such losses, claims, damages, liabilities,
costs and expenses resulted primarily from any wrongful action on such
Purchaser's part which was not taken by such Purchaser in reliance upon any of
the warranties, covenants or promises of any of the Issuers herein or the
documents contemplated hereby or the certificates delivered by any of the
Issuers pursuant hereto or thereto, whether or not the transactions contemplated
by this Agreement are consummated, which investigation or proceeding requires
such Purchaser's participation or is commenced or filed against such Purchaser
because of this Agreement or the transactions contemplated hereby.  The
obligations of the Issuers under this Article 9 shall survive the payment or
prepayment of the Notes and the Series A Shares, at maturity, upon redemption or
otherwise.

          Promptly after receipt by an indemnified party under this Article 9 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under this
Article 9, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Article 9.  In case any such action is brought against any indemnified party and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the consent of the indemnified party (which
consent shall not be unreasonably withheld), be counsel to the indemnifying
party), and after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party will
not be liable to such indemnified party under this Article 9 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of


                                          13
<PAGE>

any pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.  No indemnified party may effect any settlement or
compromise of any pending or threatened action in respect of which such
indemnified party has sought or may seek indemnification hereunder without the
prior written consent of each indemnifying party.

     10.  CONTRIBUTION.  If the indemnification provided for in Article 9 is
unavailable or insufficient to hold harmless an indemnified party under Article
9, then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party as a result of the losses, claims, damages,
liabilities, costs and expenses referred to in Article 9 in such proportion as
is appropriate to reflect the relative fault of the Issuers on the one hand and
the Purchaser on the other in connection with the actions which resulted in such
claim as well as any other relevant equitable considerations.  The amount paid
by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in this paragraph shall be deemed to include any legal
or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any action or claim.

          The obligations of the Issuers under Articles 9 and 10 shall be in
addition to any liability which the Issuers may otherwise have and shall extend,
upon the same terms and conditions, to each Purchaser, its representatives,
officers and directors and each person, if any, who controls such Purchaser
within the meaning of the Securities Act or the Exchange Act.

          11.  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, but all such counterparts shall constitute one and the same
instrument.

          12.  SURVIVAL OF COVENANTS, ETC.; SUCCESSORS AND ASSIGNS.  All
covenants, agreements, representations and warranties made by the parties in
this Agreement or incorporated by reference herein and in certificates or other
documents delivered pursuant to it shall remain in full force and effect,
regardless of any investigation or statement as to the results thereof, made by
or on behalf of the Issuers, the Purchasers or any person controlling any of
them and will survive the execution and delivery of the Notes and Series A
Shares to the Purchasers and payment by the Purchasers therefor.  All such
covenants, agreements, representations and warranties shall be binding upon any
successors and assigns of the Issuers.  In


                                          14
<PAGE>

addition, whether or not any express assignment has been made except as
otherwise provided in Article 7 hereof, all holders of the Notes and Series A
Shares who hold such Notes or Series A Shares as transferees from the Purchasers
hereunder shall be entitled to the benefit of all covenants and agreements of
the Issuers made or to be performed or observed by the Issuers (but not the
representations and warranties made by the Issuers herein or in any document or
agreement which is incorporated by reference herein).

          13.  COMMUNICATIONS AND NOTICES.  Except as otherwise provided in this
Agreement, all communications and notices provided for in this Agreement shall
be in writing and (i) if to any of the Issuers mailed by first class mail or
overnight courier to them at EnviroSystems Corp. c/o Environmental Systems
Products Holdings Inc., 7 Kripes Road, East Granby, Connecticut 06026,

the Purchasers specified in the signature pages hereto, or to such other address
and for such attention as any Purchaser may from time to time designate to the
Parent or the Company in writing.

          14.  LAW GOVERNING.  This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of New York,
without regard to the principles of conflicts of laws thereof.

          15.  SEVERABILITY.  In case any one or more of the provisions
contained in this Agreement or in any instrument contemplated hereby, or any
application thereof, shall be invalid, illegal or unenforceable in any respect,

      WHEREAS, the Boards of Directors of Parent, Purchaser and the Company have
each determined that it is in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein; and

      WHEREAS, the Company's common stock consists of three classes as follows:
Class A Common Stock, par value $.01 per share ("Class A Common Stock"), Class B
Common Stock, par value $.01 per share ("Class B Common Stock") and Class C
Common Stock, par value $.01 per share ("Class C Common Stock"; together with
Class A Common Stock and Class B Common Stock, being hereinafter collectively
referred to as "Company Common Stock"); and

      WHEREAS, in furtherance of such acquisition, it is proposed that Purchaser
shall make a cash tender offer (the "Offer") to acquire all the issued and
outstanding shares of the Company's Class A Common Stock (shares of Class A
Common Stock, being hereinafter collectively referred to as "Shares") for $17.25
per Share (such amount, or any greater amount per Share paid pursuant to the
Offer, being hereinafter referred to as the "Per Share Amount") net to the
seller in cash, upon the terms and subject to the conditions of this Agreement
and the Offer; and

      WHEREAS, the Board of Directors of the Company (the "Board") has
unanimously approved the making of the Offer and resolved and agreed to
recommend that holders of Shares tender their Shares pursuant to the Offer; and

      WHEREAS, also in furtherance of such acquisition, the Boards of Directors
of Parent, Purchaser and the Company have each approved the merger (the
"Merger") of Purchaser with and into the Company in accordance with the General
Corporation Law of the State of Delaware ("Delaware Law") upon the terms and
subject to the conditions set forth herein; and

      WHEREAS, Parent and Purchaser are unwilling to enter into this Agreement
unless, contemporaneously with the execution and delivery hereof, certain
stockholders of the Company each enter into an agreement providing for certain
matters with respect to certain shares of the Company Common Stock beneficially
owned by them as set forth therein and such stockholders have each agreed to
execute and deliver such agreement.

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,
Parent, Purchaser and the Company hereby agree as follows:

the then outstanding Shares on a primary basis, and (ii) 100 percent of the
Shares that are issuable upon conversion (and assuming conversion thereof) of
all of the then outstanding shares of Class B Common Stock and Class C Common
Stock, shall have been validly tendered and not withdrawn prior to the
expiration of the Offer and also shall be subject to the satisfaction of the
other conditions set forth in Annex A hereto. Purchaser expressly reserves the
right to waive any such condition, to increase the price per Share payable in
the Offer, and to make any other changes in the terms and conditions of the
Offer; provided, however, that the Minimum Condition may not be waived without
the prior approval of the Company (except that the Minimum Condition may be
waived without such prior approval if at least the number of Shares, assuming
conversion of all shares of Class B Common Stock and Class C Common Stock into
Shares, that when added to any Shares already owned by Parent shall constitute a
majority of the then outstanding Shares on a primary basis, shall have been
validly tendered and not withdrawn prior to the expiration of the Offer) and
that no change may be made which decreases the price per Share payable in the
Offer, reduces the maximum number of Shares to be purchased in the Offer,
imposes conditions to the Offer in addition to those set forth in Annex A hereto
or otherwise is materially adverse to the Company or the holders of Shares.
Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, (i) extend the Offer for up to 30 Business Days beyond the scheduled
expiration date (the initial scheduled expiration date being September 30, 1998)
if, at the scheduled expiration date of the Offer, any of the conditions (other
than the Minimum Condition or the condition specified in paragraph (g) of Annex
A) to Purchaser's obligation to accept for payment, and to pay for, the Shares
shall not be satisfied or waived, (ii) extend the Offer for any period required
by the SEC Rules applicable to the Offer, (iii) extend the Offer for an
aggregate period of not more than ten Business Days beyond the latest applicable
date that would otherwise be permitted under clause (i) or (ii) of this
sentence, if as of such date, the Minimum Condition shall not be satisfied or
waived or (iv) extend the Offer for so long as this Agreement shall remain in
effect if the condition specified in paragraph (g) of Annex A shall not be
satisfied or waived; provided, however, that (A) if the waiting period under the
HSR Act shall not have expired or been terminated on the scheduled expiration
date of the Offer or a temporary restraining order prohibiting the purchase of
the Shares shall have been issued by a court of competent jurisdiction, the
Purchaser shall extend the Offer from time to time until five Business Days
after the expiration or termination of the waiting period under the HSR Act or
the lifting of such temporary restraining order and (B) if the condition set
forth in paragraph (c) or (d) of Annex A shall not have been satisfied, the
Purchaser shall, so long as the breach can be cured and the Company is
vigorously attempting to cure such breach, extend the Offer from time to time
until five Business Days after such breach is cured. The Per Share Amount shall
be net to the seller in cash, upon the terms and subject to the conditions of
the Offer. Subject to the terms and conditions of the Offer, Purchaser shall
pay, as promptly as practicable after expiration of the Offer, for all Shares
validly tendered and not withdrawn.

      (b) As soon as reasonably practicable on the date of commencement of the
Offer, Purchaser shall file with the SEC (i) a Tender Offer Statement on
Schedule 14D-1 (together with all amendments and supplements thereto, the
"Schedule 14D-1") with respect to the Offer. The Schedule 14D-1 shall contain or
shall incorporate by reference an offer to purchase (the "Offer to Purchase")
and forms of the related letter of transmittal and any related summary
advertisement (the Schedule 14D-1, the Offer to Purchase and such other
documents, together with all supplements and amendments thereto, being referred
to herein collectively as the "Offer Documents"). Parent, Purchaser and the
Company agree to correct promptly any information provided by any of them for
use in the Offer Documents which shall have become false or misleading, and
Parent and Purchaser further agree to take all steps necessary to cause the
Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer
Documents as so corrected to be disseminated to holders of Shares, in each case
as and to the extent required by applicable federal securities laws.

      (c) In the event that, upon the expiration of the Offer (including any
extension thereof made in accordance with Section 1.01(a)), the Minimum
Condition shall not have been satisfied or waived, the Company shall file, and
Parent and Purchaser shall use all reasonable efforts to assist the Company in
filing, as promptly as practicable, but

in no event later than five Business Days following such expiration date, the
Proxy Statement with the SEC under the Exchange Act pursuant to Section 6.02 for
the purpose of considering and taking action on this Agreement and the Merger.

      SECTION 1.02. Company Action. (a) The Company hereby approves of and
consents to the Offer and represents that (i) the Board, at a meeting duly

Agreement and the Transactions, including the Offer and the Merger, are fair to
and in the best interests of the holders of Shares, (B) approved and adopted
this Agreement and the Transactions (such approval and adoption having been made

fiduciary duties of the Board under applicable law as determined by the Board in
good faith after receiving advice from independent counsel, the Company hereby
consents to the inclusion in the Offer Documents of the recommendation of the
Board described in the immediately preceding sentence. The Company has been
advised by each of its directors and executive officers that they intend either
to tender all Shares beneficially owned by them to Purchaser pursuant to the
Offer or to vote such Shares in favor of the approval and adoption by the
stockholders of the Company of this Agreement and the Transactions.

      (b) As soon as reasonably practicable on the date of commencement of the
Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 (together with all amendments and supplements
thereto, the "Schedule 14D-9") containing, subject to the fiduciary duties of
the Board under applicable law as determined by the Board in good faith after
receiving advice from independent counsel, the recommendation of the Board
described in Section 1.02(a) and shall disseminate the Schedule 14D-9 to the
extent required by Rule 14d-9 promulgated under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and any other applicable federal
securities laws. The Company, Parent and Purchaser agree to correct promptly any
information provided by any of them for use in the Schedule 14D-9 which shall
have become false or misleading, and the Company further agrees to take all
steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the
SEC and disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws.

      (c) The Company shall promptly furnish to Purchaser mailing labels
containing the names and addresses of all record holders of Shares and with
security position listings of Shares held in stock depositories, each as of a
recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
beneficial owners of Shares. The Company shall furnish to Purchaser such
additional information, including, without limitation, updated listings and
computer files of stockholders, mailing labels and security position listings,
and such other assistance as Parent, Purchaser or their agents may reasonably
request. Subject to the requirements of applicable law, and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Offer or the Merger, Parent and Purchaser
shall hold in confidence the information contained in such labels, listings and
files, shall use such information only in connection with the Offer and the
Merger, and, if this Agreement shall be terminated in accordance with Section
8.01, shall deliver to the Company all copies of such information then in their
possession.

      SECTION 1.03. Employee Stock Options. (a) Each stock option (a "Company
Stock Option") outstanding at the time of the purchase of Shares pursuant to the
Offer in accordance with Section 1.01,

whether or not exercisable and whether or not vested, under any stock option
plan of the Company, or any of its Affiliates or any agreement to which the
Company or any of its Affiliates is a party (the "Company Stock Option Plans"),
shall be canceled by the Company immediately following the purchase of Shares
pursuant to the Offer in accordance with Section 1.01 and each holder of a
canceled Company Stock Option shall be entitled to receive immediately
thereafter from the Company in consideration for the cancellation of such
Company Stock Option an amount (the "Option Spread") equal to the product of (i)
the number of Shares previously subject to such Company Stock Option and (ii)
the excess, if any, of the Per Share Amount over the exercise price per share of
Company Common Stock previously subject to such Company Stock Option. The Option
Spread, after reduction for applicable tax withholding, if any, shall be paid in
cash. No interest shall accrue or be paid on the Option Spread for the benefit
of the holder of such canceled Company Stock Option.

      (b) On the day immediately following the purchase of Shares pursuant to
the Offer in accordance with Section 1.01, Purchaser shall cause to be wired to
an account designated by the Company not less than three days prior to the
expiration of the Offer an amount sufficient to enable the Company to make the

      SECTION 2.01. The Merger. Upon the terms and subject to the conditions set

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


      (b) The By-laws of Purchaser, as in effect immediately prior to the
Effective Time, shall be the By-laws of the Surviving Corporation until
thereafter amended as provided by law, the Certificate of Incorporation of the
Surviving Corporation and such By-laws.

      SECTION 2.05. Directors and Officers. The directors of Purchaser
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of

the Surviving Corporation, in each case until their respective successors are

      SECTION 2.06. Conversion of Securities. At the Effective Time, by virtue
of the Merger and without any action on the part of Purchaser, the Company or
the holders of any of the following securities:

            (a) Each share of Company Common Stock issued and outstanding
      immediately prior to the Effective Time (other than any shares of Company
      Common Stock to be canceled pursuant to Section 2.06(b) and any Dissenting
      Shares (as hereinafter defined)) shall be canceled and shall be converted
      automatically into the right to receive an amount equal to the Per Share
      Amount in cash (the "Merger Consideration") payable, without interest, to
      the holder of such share of Company Common Stock, upon surrender, in the
      manner provided in Section 2.09, of the certificate that formerly
      evidenced such share of Company Common Stock;

            (b) Each share of Company Common Stock held in the treasury of the
      Company and each share of Company Common Stock owned by Purchaser, Parent
      or any direct or indirect wholly owned Subsidiary of Parent or of the
      Company immediately prior to the Effective Time shall be canceled without
      any conversion thereof and no payment or distribution shall be made with
      respect thereto; and

            (c) Each share of Common Stock, par value $.01 per share, of
      Purchaser issued and outstanding immediately prior to the Effective Time
      shall be converted into, and exchanged for, one validly issued, fully paid
      and nonassessable share of Common Stock, par value $.01 per share, of the
      Surviving Corporation.

      SECTION 2.07. Employee Stock Options. In the event that the Company Stock

outstanding at the Effective Time, whether or not exercisable and whether or not
vested, under any Company Stock Option Plan, shall be canceled by the Company at
the Effective Time and each holder of a canceled Company Stock Option shall be
entitled to receive immediately thereafter from the Company in consideration for
the cancellation of such Company Stock Option the Option Spread. The Option
Spread, after reduction for applicable tax withholding, if any, shall be paid in

of the holder of such canceled Company Stock Option.

      SECTION 2.08. Dissenting Shares. (a) Notwithstanding any provision of this

immediately prior to the Effective Time and which are held by stockholders who
shall have not voted in favor of the Merger or consented thereto in writing and
who shall have demanded properly in writing an appraisal for such shares of
Company Common Stock in accordance with Section 262 of Delaware Law
(collectively, the "Dissenting Shares") shall not be converted into or represent
the right to receive the Merger Consideration. Such stockholders shall be
entitled to receive payment of the appraised value of such shares of Company
Common Stock held by them in accordance with the provisions of such Section 262,
except that all Dissenting Shares held by stockholders who shall have failed to
perfect or who effectively shall have withdrawn or lost their rights to
appraisal of 

<PAGE>

                                                                         Page 6
- --------------------------------------------------------------------------------


such shares of Company Common Stock under such Section 262 shall thereupon be
deemed to have been converted into and to have become exchangeable for, as of
the Effective Time, the right to receive the Merger Consideration, without any
interest thereon, upon surrender, in the manner provided in Section 2.09 of the
certificate or certificates that formerly evidenced such shares of Company
Common Stock.

      (b) The Company shall give Purchaser (i) prompt notice of any written
demands for fair value, withdrawals of demands for fair value and any other
instruments served pursuant to applicable law received by the Company relating
to stockholders' rights of appraisal and (ii) the opportunity to direct all
negotiations and proceedings with respect to demands for appraised value under
Section 262 of Delaware Law. The Company shall not, except with the prior
written consent of Purchaser, voluntarily make any payment with respect to any
demands for appraised value of Dissenting Shares or offer to settle or settle
any such demands.

      SECTION 2.09. Surrender of Shares; Stock Transfer Books. (a) As of the
Effective Time, Purchaser shall deposit, or shall cause to be deposited, with a
bank or trust company designated by Parent or Purchaser to act as its paying
agent (the "Paying Agent"), for the benefit of the holders of shares of Company
Common Stock, for payment in accordance with this Article II, through the Paying
Agent, cash in an amount equal to the Per Share Amount multiplied by the number
of Shares (assuming the conversion of all issued and outstanding shares of Class
B Common Stock and Class C Common Stock into shares of Class A Common Stock
prior to the Effective Time) outstanding immediately prior to the Effective Time
(such cash being hereinafter referred to as the "Payment Fund"). The Paying
Agent shall, pursuant to irrevocable instructions, deliver the cash contemplated
to be paid pursuant to Sections 2.06(a) and 2.08 out of the Payment Fund. The
Payment Fund shall not be used for any other purpose. The Payment Fund shall be
invested by the Paying Agent as directed by the Surviving Corporation, provided
that such investments shall be in obligations of or guaranteed by the United
States of America or of any agency thereof and backed by the full faith and
credit of the United States of America, in commercial paper obligations rated
A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard & Poor's
Rating Services, respectively, or in deposit accounts, certificates of deposit
or banker's acceptances of, repurchase or reverse repurchase agreements with, or
Eurodollar time deposits purchased from, commercial banks with capital, surplus
and undivided profits aggregating in excess of $500 million (based on the most
recent financial statements of such bank which are then publicly available at
the SEC or otherwise).

      (b) Promptly after the Effective Time, the Surviving Corporation shall
cause to be mailed to each person who was, at the Effective Time, a holder of
record of shares of Company Common Stock entitled to receive the Merger
Consideration pursuant to Section 2.06(a) a form of letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
certificates evidencing such shares of Company Common Stock (the "Certificates")
shall pass, only upon proper delivery of the Certificates to the Paying Agent)
and instructions for use in effecting the surrender of the Certificates pursuant
to such letter of transmittal. Upon surrender to the Paying Agent of a
Certificate, together with such letter of transmittal, duly completed and
validly executed in accordance with the instructions thereto, and such other
documents as may be required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each share of Company Common Stock formerly evidenced by such
Certificate, and such Certificate shall then be canceled. No interest shall
accrue or be paid on the Merger Consideration payable upon the surrender of any
Certificate for the benefit of the holder of such Certificate. If payment of the
Merger Consideration is to be made to a person other than the person in whose
name the surrendered Certificate is registered on the stock transfer books of
the Company, it shall be a condition of payment that the Certificate so
surrendered shall be endorsed properly or otherwise be in proper form for
transfer and that the person requesting such payment shall have paid all
transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such 

<PAGE>

                                                                         Page 7
- --------------------------------------------------------------------------------


taxes either have been paid or are not applicable.

      (c) At any time following the sixth month after the Effective Time, the
Surviving Corporation shall be entitled to require the Paying Agent to deliver
to it any funds which had been made available to the Paying Agent and not
disbursed to holders of shares of Company Common Stock (including, without
limitation, all interest and other income received by the Paying Agent in
respect of all funds made available to it), and thereafter such holders shall be
entitled to look to the Surviving Corporation (subject to abandoned property,
escheat and other similar laws) only as general creditors thereof with respect
to any Merger Consideration that may be payable. Notwithstanding the foregoing,
neither the Surviving Corporation nor the Paying Agent shall be liable to any
holder of a Share for any Merger Consideration delivered in respect of such
Share to a public official pursuant to any abandoned property, escheat or other
similar law.

      (d) At the close of business on the day of the Effective Time, the stock
transfer books of the Company shall be closed and thereafter there shall be no
further registration of transfers of shares of Company Common Stock on the
records of the Company. From and after the Effective Time, the holders of shares
of Company Common Stock outstanding immediately prior to the Effective Time
shall cease to have any rights with respect to such shares of Company Common
Stock except as otherwise provided herein or by applicable law.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      The Company hereby represents and warrants to Parent and Purchaser that:

      SECTION 3.01. Organization and Qualification; Subsidiaries. Each of the
Company and each Subsidiary of the Company is duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization and has
the requisite power and authority and all necessary governmental approvals to
own, lease and operate its properties and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing or in
good standing or to have such power, authority and governmental approvals does
not, individually or in the aggregate, have a Material Adverse Effect. Each of
the Company and each Subsidiary is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of the properties owned, leased or operated by it or the nature of
its business makes such qualification or licensing necessary, except for such
failures to be so qualified or licensed and in good standing that do not,
individually or in the aggregate, have a Material Adverse Effect. A true and
complete list of all the Subsidiaries, together with the jurisdiction of
organization of each Subsidiary and the percentage of the outstanding capital
stock of each Subsidiary owned by the Company and each other Subsidiary, is set
forth in Schedule 3.01. Except as disclosed in Schedule 3.01, the Company does
not directly or indirectly own any equity or similar interest in, or any
interest convertible into or exchangeable or exercisable for any equity or
similar interest in, any corporation, partnership, joint venture or other
business association or entity.

      SECTION 3.02. Certificate of Incorporation and By-laws. The Company has
heretofore furnished to Parent a complete and correct copy of the Certificate of
Incorporation and the By-laws or equivalent organizational documents, each as
amended to date, of the Company and each Subsidiary. Such Certificates of
Incorporation and By-Laws or equivalent organizational documents are in full
force and effect, and neither the Company nor any Subsidiary is in violation of
any provision thereof.

<PAGE>

                                                                         Page 8
- --------------------------------------------------------------------------------


      SECTION 3.03. Capitalization. The authorized capital stock of the Company
consists of 40,000,000 Shares, 5,000,000 shares of Class B Common Stock and
5,000,000 shares of Class C Common Stock. As of the date hereof, (i) 8,842,248
Shares, 1,249,749 shares of Class B Common Stock and 2,026,111 shares of Class C
Common Stock are issued and outstanding, all of which are validly issued, fully
paid and nonassessable, (ii) 4,388,091 Shares, no shares of Class B Common Stock
and no shares of Class C Common Stock are held in the treasury of the Company,
(iii) no Shares, no shares of Class B Common Stock and no shares of Class C
Common Stock are held by the Subsidiaries, (iv) 2,830,285 Shares, no shares of
Class B Common Stock and no shares of Class C Common Stock are reserved for
issuance pursuant to currently outstanding stock options granted pursuant to the
Company's Stock Option Plans and (v) 589,660 Shares, no shares of Class B Common
Stock and no shares of Class C Common Stock are reserved for issuance pursuant
to stock options to be granted pursuant to the Company's Stock Option Plans.
Each of the outstanding shares of capital stock or other securities of each
Subsidiary is duly authorized, validly issued, fully paid and nonassessable and
owned by a direct or indirect wholly-owned subsidiary of the Company, free and
clear of any lien, pledge, security interest, claim or other encumbrance. Except
as set forth in this Section 3.03 or in the Certificate of Incorporation of the
Company, neither the Company nor any Subsidiary has granted any options,
warrants or other rights, or entered into any agreements, arrangements or
commitments of any character relating to the issued or unissued capital stock of
the Company or any Subsidiary or obligating the Company or any Subsidiary to
issue or sell any shares of capital stock of, or other equity interests in, the
Company or any Subsidiary. All Shares subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, will be duly authorized, validly issued, fully paid and
nonassessable. Schedule 3.03 contains a correct and complete list of all options
to purchase capital stock of the Company or any Subsidiary. Except as set forth
on Schedule 3.03, there are no outstanding contractual obligations of the
Company or any Subsidiary to provide funds to, or make any investment (in the
form of a loan, capital contribution or otherwise) in, or to repurchase, redeem
or otherwise acquire any shares of capital stock of the Company or any
Subsidiary or any other person other than to Subsidiaries in the ordinary course
of business consistent with past practice.

      SECTION 3.04. Authority Relative to this Agreement. The Company has all
necessary power and authority to execute and deliver this Agreement, to perform
its obligations hereunder and to consummate the transactions contemplated hereby
(the "Transactions"). The execution and delivery of this Agreement by the
Company and the consummation by the Company of the Transactions have been duly
and validly authorized by all necessary corporate action, and no other corporate
proceedings on the part of the Company are necessary to authorize this Agreement
or to consummate the Transactions (other than, with respect to the Merger, the
approval and adoption of this Agreement by the holders of a majority of the then
outstanding Shares if and to the extent required by applicable law, and the
filing and recordation of appropriate merger documents as required by Delaware
Law). This Agreement has been duly and validly executed and delivered by the
Company and, assuming the due authorization, execution and delivery by Parent
and Purchaser, constitutes a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

      SECTION 3.05. No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by the Company does not, and the
performance of this Agreement by the Company will not, (i) conflict with or
violate the Certificate of Incorporation or By-laws or equivalent organizational
documents of the Company or any Subsidiary, (ii) conflict with or violate any
law, rule, regulation, order, judgment or decree applicable to the Company or
any Subsidiary or by which any property or asset of the Company or any
Subsidiary is bound or affected other than conflicts or violations that do not,
individually or in the aggregate, have a Material Adverse Effect, or (iii)
except as set forth on Schedule 3.05(a), result in any

time or both would become a default) under, require any third-party consents,
approvals, or authorizations, give to others any right of termination,
amendment, acceleration or cancellation of, or result in the creation of a lien
or other encumbrance on any property or asset of the Company or any Subsidiary
pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation, other than
breaches, defaults or other occurrences that do not, individually or in the
aggregate, have a Material Adverse Effect.

      (b) The execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification

of such entity's accountants with respect thereto (collectively, the "Parent
Audited Statements"). Parent has furnished the Company with unaudited interim
financial statements for the period ended June 30, 1998 (collectively, the
"Parent Unaudited Statements").

      (b) Each of the Parent Audited Statements and the Parent Unaudited
Statements (including any notes thereto) was prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods indicated and each fairly presented the consolidated

consolidated subsidiaries as at the respective dates thereof and for the
respective periods indicated therein (except as otherwise noted therein and
subject, in the case of the Parent Unaudited Statements, to normal and recurring
year-end adjustments which are not expected to have either, individually or in
the aggregate, a material adverse effect on the business, financial condition,
results of operations or prospects of Parent and its Subsidiaries, taken as a
whole).

      (c) Except as and to the extent set forth on the consolidated balance
sheet of Parent as at December 31, 1997, including the notes thereto, neither
Parent nor any of its Subsidiaries has any liability or obligation of any nature

reflected on a balance sheet prepared in accordance with generally accepted
accounting principles, except for liabilities and obligations that do not,
individually or in the aggregate, have a material adverse effect on the
business, financial condition, results of operations or prospects of Parent.

      SECTION 4.08. Absence of Certain Changes or Events. From December 31, 1997
through the date hereof, there has not been a material adverse effect on the
business, financial condition, results of operations or prospects of Parent and
its Subsidiaries, taken as a whole, and, to the knowledge of Parent, there is no
event or prospective event that reasonably would be expected to cause such an
effect.

                              ADDITIONAL AGREEMENTS

      SECTION 6.01. Stockholders' Meeting. (a) If required by applicable law in
order to consummate the Merger, the Company, acting through the Board, shall, in
accordance with applicable law and the Company's Certificate of Incorporation
and By-laws, (i) duly call, give notice of, convene and hold an annual or
special meeting of its stockholders as soon as practicable following the
consummation or the termination of the Offer, as applicable, for the purpose of
considering and taking action on this Agreement and the transactions
contemplated hereby (the "Stockholders' Meeting") and (ii) subject to the
fiduciary duties of the Board under applicable law as determined by the Board in
good faith after receiving the advice of independent counsel, (A) include in the
Proxy Statement the recommendation of the Board that the stockholders of the

reasonable best efforts to obtain such approval and adoption. At the
Stockholders' Meeting, Parent and Purchaser shall cause all Shares then owned by
them and their Subsidiaries to be voted in favor of the approval and adoption of
this Agreement and the Transactions.

      (b) Notwithstanding the foregoing, in the event that Purchaser shall
acquire at least 90 percent of the then outstanding Shares, the parties hereto
agree, at the request of Purchaser, subject to Article VII, to take all
necessary and appropriate action to cause the Merger to become effective, in
accordance with Section 253 of Delaware Law, as soon as reasonably practicable
after such acquisition,

<PAGE>

                                                                         Page 19

without a meeting of the stockholders of the Company.

      SECTION 6.02. Proxy Statement. If required by applicable law, the Company
shall, within the time period provided in Section 1.01(c) or as soon as
practicable following the consummation of the Offer, as applicable, file the
Proxy Statement with the SEC under the Exchange Act, and shall use its
reasonable best efforts to have the Proxy Statement cleared by the SEC. Parent,
Purchaser and the Company shall cooperate with each other in the preparation of
the Proxy Statement, and the Company shall notify Parent of the receipt of any
comments of the SEC with respect to the Proxy Statement and of any requests by
the SEC for any amendment or supplement thereto or for additional information
and shall provide to Parent promptly copies of all correspondence between the
Company or any representative of the Company and the SEC. The Company shall give
Parent and its counsel the opportunity to review the Proxy Statement prior to
its being filed with the SEC and shall give Parent and its counsel the
opportunity to review all amendments and supplements to the Proxy Statement and
all responses to requests for additional information and replies to comments
prior to their being filed with, or sent to, the SEC. Each of the Company,
Parent and Purchaser agrees to use its reasonable best efforts, after
consultation with the other parties hereto, to respond promptly to all such
comments of and requests by the SEC and to cause the Proxy Statement and all
required amendments and supplements thereto to be mailed to the holders of
Shares entitled to vote at the Stockholders' Meeting at the earliest practicable

      SECTION 6.03. Company Board Representation; Section 14(f). (a) Promptly
upon the purchase by Purchaser of Shares pursuant to the Offer, and from time to
time thereafter, Purchaser shall be entitled to designate up to such number of
directors, rounded up to the next whole number, on the Board as shall give
Purchaser representation on the Board equal to the product of the total number
of directors on the Board (giving effect to the directors elected pursuant to
this sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Purchaser or any Affiliate of Purchaser following such
purchase bears to the total number of Shares then outstanding, and the Company
shall, at such time, promptly take all actions necessary to cause Purchaser's
designees to be elected as directors of the Company, including increasing the
size of the Board or securing the resignations of incumbent directors or both.
At such times, the Company shall use its reasonable best efforts to cause
persons designated by Purchaser to constitute the same percentage of each
committee of the Board as persons designated by Purchaser to constitute the
Board to the extent permitted by applicable law.

      (b) The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under this Section 6.03 and shall include in the
Schedule 14D-9 such information with respect to the Company and its officers and
directors as is required under Section 14(f) and Rule 14f-1 to fulfill such
obligations. Parent or Purchaser shall supply to the Company and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by such Section 14(f) and
Rule 14f-1.

      (c) Following the election of designees of Purchaser pursuant to this
Section 6.03, prior to the Effective Time, any amendment of this Agreement or
the Certificate of Incorporation or By-laws of the Company, any termination of
this Agreement by the Company, any extension by the Company of the time for the
performance of any of the obligations or other acts of Parent or Purchaser or
waiver of any of the Company's rights hereunder shall require the concurrence of
a majority of the directors of the Company then in office who neither were
designated by Purchaser nor are employees of the Company.

      SECTION 6.04. Access to Information; Confidentiality. (a) In connection
with their investigation of the business of the Company, Parent and Purchaser
have received from the Company certain estimates, projections and other
forecasts for the business of the Company, and certain plan and budget

<PAGE>

                                                                         Page 20
- --------------------------------------------------------------------------------


information, including, without limitation, estimates, projections, forecasts,
plans or budgets relating to the Company's Remote Sensing Technology. Each of
Parent and Purchaser acknowledges (i) that there are uncertainties inherent in
attempting to make such estimates, projections, forecasts, plans and budgets,
that it is familiar with such uncertainties, (ii) that it is taking full
responsibility for making its own evaluation of the adequacy and accuracy of all
estimates, projections, forecasts, plans and budgets so furnished to it, and
(iii) that it will not assert any claim against the Company or any of its
Affiliates or any of their respective directors, officers, employees, agents,
stockholders, consultants, investment bankers, accountants or representatives,
or hold the Company or any such persons liable with respect thereto, except for
claims based on fraud or intentional misrepresentation as to which the foregoing
clause (iii) is not applicable. Accordingly, the Company makes no representation
or warranty with respect to any estimates, projections, forecasts, plans or
budgets referred to in this Section 6.04(a).

      (b) From the date hereof to the Effective Time, the Company shall, and
shall cause the Subsidiaries and the officers, directors, employees, auditors
and agents of the Company and the Subsidiaries to, afford the officers,
employees and agents of Parent and Purchaser and persons providing or committing
to provide Parent or Purchaser with financing for the Transactions reasonable
access at all reasonable times to the officers, employees, agents, properties,
offices and other facilities, books and records of the Company and each
Subsidiary, and shall promptly furnish Parent and Purchaser and persons
providing or committing to provide Parent or Purchaser with financing for the
Transactions with (i) a copy of each report, statement, schedule and other
document filed or received by the Company or any of its Subsidiaries pursuant to
the requirements of federal or state securities laws or filed with any other
governmental or regulatory authority and (ii) all financial, operating and other
data and information as Parent or Purchaser, through its officers, employees or
agents, may reasonably request.

      (c) Purchaser agrees to be bound by the terms of the confidentiality
agreement, dated May 8, 1998 (the "Confidentiality Agreement"), between Parent
and the Company as if Purchaser was a party thereto. All information obtained by
Parent or Purchaser pursuant to this Section 6.04 shall be kept confidential in
accordance with the Confidentiality Agreement.

      SECTION 6.05. No Solicitation of Transactions. (a) The Company agrees that
neither it nor any of its Subsidiaries nor any of their officers, directors or
agents shall, directly or indirectly, engage in any negotiations concerning, or
provide any confidential information or data to, or have any discussions with
any Person relating to an Acquisition Proposal; provided, however, that nothing
contained herein shall prevent the Company or the Board from engaging in any
negotiations or discussions with any Person who has made an unsolicited bona
fide written Acquisition Proposal or recommending such an Acquisition Proposal
to the stockholders of the Company (or withdrawing or modifying, in any manner
adverse to Parent and Purchaser, its approval or recommendation of the Offer,
the Agreement, the Merger or any other Transaction), if and only to the extent
that (i) the Board determines in good faith, after consultation with outside
legal counsel that such action is necessary in order for its directors to comply
with their fiduciary duties under applicable law and (ii) the Board determines
in good faith (after consultation with its financial advisor) that such
Acquisition Proposal, if accepted, is reasonably likely to be consummated,
taking into account all legal, financial and regulatory aspects of the proposal
and the financial capacity and any other relevant characteristics of the Person
making the proposal and would, if consummated, result in a transaction more
favorable to the Company's stockholders from a financial point of view than the
Transactions. The Company agrees that it will immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any of the foregoing. The Company also
agrees that it will promptly request each Person that has heretofore executed a
confidentiality agreement in connection with its consideration of acquiring it
or any of its Subsidiaries to return or destroy all confidential information
heretofore furnished to such Person by or on behalf of the Company or any of its
Subsidiaries. The

Company agrees that it will notify Parent and Purchaser immediately if any
inquiries, proposals or offers are received by, any such information is
requested from, or any such discussion or negotiations are sought to be
initiated or continued with any of its officers, director or agents, indicating,
in connection with such notice, the name of such Person and the material terms
and conditions of any proposals or offers and thereafter shall keep Parent and
Purchaser informed, on a current basis, on the status and material terms of any
such proposals or offers and the status of any such negotiations or discussions.
"Acquisition Proposal" shall mean (i) any proposal or offer from any person
relating to any direct or indirect acquisition or purchase of (A) all or a
substantial part of the assets of the Company, or (B) over 15% of the voting
securities of the Company; (ii) any tender offer or exchange offer as defined
pursuant to the Exchange Act that if consummated would result in any person
beneficially owning 15% or more of the voting securities of the Company; or
(iii) any merger, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving the Company other than
the Transactions.

      (b) Nothing contained in this Section 6.05 shall prohibit the Company or
Parent from taking and disclosing to their respective shareholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or issuing a
communication that meets the requirements of Rule 14d-9(e) promulgated under the
Exchange Act.

      SECTION 6.06. Employee Benefits Matters. Annex B hereto sets forth certain
agreements among the parties hereto with respect to the Plans and other employee
benefits matters.

      SECTION 6.07. Directors' and Officers' Indemnification and Insurance. (a)
The Certificate of Incorporation of the Surviving Corporation shall contain
provisions (collectively, "Indemnification Provisions") no less favorable with
respect to indemnification than are set forth in Article 8 of the Certificate of
Incorporation of the Company, which provisions shall not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would affect adversely the rights thereunder of individuals who at
the Effective Time were directors, officers, employees, fiduciaries or agents of
the Company, unless such modification shall be required by law. Parent hereby
agrees that, for a period of six years from the Effective Time, it shall
absolutely and unconditionally guarantee the prompt performance and satisfaction
of all obligations of the Surviving Corporation under the Indemnification
Provisions.

      (b) Parent and the Surviving Corporation each shall use its best efforts
to maintain in effect for six years from the Effective Time, if available, the
current directors' and officers' liability insurance policies maintained by the
Company (provided that Parent and the Surviving Corporation may substitute
therefor policies of at least the same coverage containing terms and conditions
which are not materially less favorable) with respect to matters occurring prior
to the Effective Time; provided, however, that if the existing policies expire,
are terminated or canceled during such period Parent or the Surviving
Corporation will obtain substantially similar policies. Notwithstanding the
foregoing, in no event shall Parent or the Surviving Corporation be required to
expend pursuant to this Section 6.07(b) more than an amount per year equal to
200% of current annual premiums paid by the Company for such insurance (which
premiums the Company represents and warrants to be $232,000 in the aggregate);
provided, however, that, in the event of an expiration, termination or
cancellation of such current policies, Parent or the Surviving Corporation shall
be required to obtain as much coverage as is possible under substantially
similar policies for $464,000 in aggregate annual premiums.

      SECTION 6.08. Further Action; Reasonable Best Efforts. (a) Upon the terms
and subject to the conditions hereof, each of the parties hereto shall (i) make
promptly its respective filings, and thereafter make any other required
submissions, under the HSR Act with respect to the Transactions and (ii) use its
reasonable best efforts to take, or cause to be taken, all appropriate action,
and to do, or cause to be done, all 

<PAGE>

                                                                         Page 22
- --------------------------------------------------------------------------------


things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the Transactions, including, without limitation,
using all reasonable efforts to obtain all licenses, permits, consents,
approvals, authorizations, qualifications and orders of governmental authorities
and parties to contracts with the Company and the Subsidiaries as are necessary
for the consummation of the Transactions and to fulfill the conditions to the
Offer and the Merger. In case at any time after the Effective Time any further
action is necessary or desirable to carry out the purposes of this Agreement,
the proper officers and directors of each party to this Agreement shall use
their reasonable best efforts to take all such action.

      (b) If any "fair price," "control share acquisition" or other similar
anti-takeover statute or regulation or any applicable anti-takeover provision in
the Company's Certificate of Incorporation or By-Laws is or may become
applicable to the Company or the Transactions, each of Parent and the Company
and its Board shall grant such approvals and take such actions as are necessary
so that the Transactions may be consummated as promptly as practicable on the
terms contemplated by this Agreement and otherwise act to eliminate or minimize
the effects of such statute or regulation on the Transactions.

      (c) The Company hereby consents to the making by Parent or an Affiliate of
Parent of tender offers (the "Debt Tenders") for the Company's outstanding
9-1/8% Senior Notes due 2001 and its 9-5/8% Senior Subordinated Notes due 2003
(the "Notes"). The Company agrees to reasonably assist Parent or such Affiliate
in the timely completion of the Debt Tenders and, without limiting the
generality of the foregoing, to promptly provide Parent or such Affiliate with
all information and documentation concerning the Company and the Notes as Parent
or such Affiliate may reasonably request in connection with the making of the
Debt Tenders.

      SECTION 6.09. Public Announcements. Parent and the Company shall consult
with each other before issuing any press release or otherwise making any public
statements with respect to this Agreement or any Transaction and shall not issue
any such press release or make any such public statement without the prior
consent of the other parties, except as may be required by law or any listing
agreement with a national securities exchange to which Parent or the Company is
a party.

      SECTION 6.10. Confidentiality Agreement. The Company hereby waives the
provisions of the Confidentiality Agreement as and to the extent necessary to
permit the consummation of each Transaction. Upon the acceptance for payment of
Shares pursuant to the Offer, the Confidentiality Agreement shall be deemed to
have terminated without further action by the parties thereto.

      SECTION 6.11 Expenses. (a) Except as set forth in Section 8.03 and in
Section 6.11(b), whether or not the Offer or Merger is consummated, all costs
and expenses incurred in connection with this Agreement and the Transactions
shall be paid by the party incurring such cost or expense, except that the
expenses incurred in connection with printing and mailing the Offer Documents,
the Schedule 14D-9 and the Proxy Statement, as well as any filing fees relating
thereto, shall be shared equally by Parent and the Company.

      (b) The Company has estimated that it will incur approximately $8,500,000
of costs and expenses in connection with the Transactions (including fees and
expenses payable to attorneys and accountants, investment banks and financial
advisors in connection therewith). The Company agrees that is shall not incur
costs and expenses in excess of such amount without obtaining the prior approval
of Parent.

      any law, rule, regulation, executive order, decree, injunction or other
      order (whether temporary, preliminary or permanent) (a "Governmental
      Order") which is then in effect and has the effect of prohibiting
      consummation of the Merger; and

            (c) Offer. Either (i) Purchaser or its permitted assignee shall have
      purchased all Shares validly tendered and not withdrawn pursuant to the

      tendered and not withdrawn pursuant to the Offer or (ii) the conditions to
      the Offer (other than the Minimum Condition) shall have been satisfied.

      Directors of Parent, Purchaser and the Company;

            (b) By either Parent, Purchaser or the Company if (i) the Effective
      Time shall not have occurred on or before December 31, 1998; provided,
      however, that the right to terminate this Agreement under this clause (i)
      shall not be available to any party whose failure to fulfill any
      obligation under this Agreement has been the cause of, or resulted in, the
      failure of the Effective Time to occur on or before such date; or (ii) any
      United States or Canadian federal, state or provincial court of competent
      jurisdiction or other United States or Canadian federal, state or

                            Employee Benefits Matters

1. In General

      Parent hereby agrees that, for a period of one year immediately following
the Effective Time, it shall, or shall cause the Surviving Corporation and its
Subsidiaries to, maintain employee benefit plans, programs, contracts and
arrangements for the benefit of active and retired employees of the Company and
its Subsidiaries immediately prior to the Effective Time (including those on
leave of absence or disability immediately prior to the Effective Time) which in
the aggregate will provide compensation and benefits that are at least
substantially equivalent to the compensation and benefits provided to such
active and retired employees under the employee benefit plans, programs,
contracts and arrangements of the Company and its Subsidiaries as in effect
immediately prior to the Effective Time and that have been disclosed or made
available to Parent, other than employee benefit plans, programs, contracts or
arrangements providing for stock options, stock purchase rights, restricted
stock or other stock-based compensation. From and after the Effective Time,
Parent shall honor, and shall cause the Surviving Corporation and its
Subsidiaries to honor all contracts, agreements, arrangements, policies, plans
and commitments of the Company and its Subsidiaries in accordance with their
terms and as in effect immediately prior to the Effective Time which are
applicable to any current or former employees or directors of the Company or any
of its Subsidiaries and that have been disclosed or made available to Parent,
other than contracts, agreements, arrangements, policies, plans or commitments
providing for stock options which shall be treated in the manner set forth in
Section 1.03 or 2.07, as applicable.

2. Service Recognition

      Employees of the Company and its Subsidiaries immediately prior to the
Effective Time (including those on leave of absence or disability immediately
prior to the Effective Time) shall receive credit for purposes of eligibility to
participate, vesting, benefit accrual and eligibility to receive benefits under
any employee benefit plan, program or arrangement established or maintained by
Parent, the Surviving Corporation or any of their respective subsidiaries for
service accrued or deemed accrued prior to the Effective Time with the Company
or any of its Subsidiaries; provided, however, that such crediting of service
shall not operate to duplicate any benefit or the funding of any such benefit or
to prevent a plan that is intended to be "qualified" within the meaning of
Section 401(a) of the Code from being so qualified.

any series of Preferred Stock (fixed in accordance with the provisions of
Section (A) of this Article VI), 

<PAGE>

if any, shall have been satisfied and after the Corporation shall have complied
with all the requirements, if any, with respect to redemption of, or the setting

the period during which such right continues (i) the then otherwise total
authorized number of directors of the Corporation shall automatically be

Preferred Stock shall be entitled to elect the additional directors so provided

<PAGE>

whichever occurs earlier. Except as otherwise provided by the Board in the
resolution or resolutions establishing such series, whenever the holders of any
series of Preferred Stock having such right to elect additional directors are
divested of such right pursuant to the provisions of such stock, the terms of
office of all such additional directors elected by the holders of such stock, or
elected to fill any vacancies resulting from death, resignation,
disqualification or removal of such additional directors, shall forthwith
terminate and the total and authorized number of directors of the Corporation
shall be reduced accordingly. Notwithstanding the foregoing, whenever, pursuant

be applied prospectively, to the extent that such repeal or modification would,
if applied retrospectively, adversely affect any limitation on the personal
liability of a director of the Corporation existing immediately prior to such
repeal or modification.

                                   ARTICLE XI

to redemption of, or the setting aside of sums as sinking funds or redemption or
purchase accounts with respect to, any series of Preferred Stock (fixed in

directors of the Corporation by all stockholders entitled to vote in such an
election, voting together as a single class.

the Corporation shall be managed by a board of directors. The board of directors

During any period when the holders of any series of Preferred Stock have the
right to elect additional directors as provided for or fixed pursuant to the
provisions of Article VI hereof, then upon commencement and for the duration of
the period during which such right continues (i) the then otherwise total
authorized number of directors of the Corporation shall automatically be
increased by such specified number of directors, and the holders of such
Preferred Stock shall be entitled to elect the additional directors so provided
for or fixed pursuant to such provisions, and (ii) each such additional director
shall serve until such director's successor shall have been duly elected and
qualified, or until such director's right to hold such office terminates
pursuant to such provisions, whichever occurs earlier. Except as otherwise
provided by the Board in the resolution or resolutions establishing such series,
whenever the holders of any series of Preferred Stock having such right to elect
additional directors are divested of such right pursuant to the provisions of
such stock, the terms of office of all such additional directors elected by the
holders of such stock, or elected to fill any vacancies resulting from death,
resignation, disqualification or removal of such additional directors, shall
forthwith terminate and the total and authorized number of directors of the
Corporation shall be reduced accordingly. Notwithstanding the foregoing,
whenever, pursuant to the provisions of Article VI hereof, the holders of any
one or more series of Preferred Stock shall have the right, voting separately as
a series or together with holders of other such series, to elect directors at an
annual or special meeting of stockholders, the election, term of office, filling
of vacancies and other features of such directorships shall be governed by the
terms of the Certificate of Incorporation.

number of directors that shall constitute the full Board, other than any
directors elected by the

holders of any series of Preferred Stock as provided for or fixed pursuant to
the provisions of Article VI hereof, shall be fixed by the Bylaws of the
Corporation.

                  Section E. Election of Directors. The directors of the
Corporation shall not be required to be elected by written ballots unless the
Bylaws of the Corporation so provide.

                                  ARTICLE VIII

                      RESTRICTION ON BUSINESS COMBINATIONS

provided that this Article X shall not eliminate or limit the liability of a 
director (i) for any breach of the director's duty of loyalty to the 
Corporation or its stockholders; (ii) for acts or omissions not in good faith 
or which involve intentional misconduct or a knowing violation of law, (iii) 
under section 174 of Title 8 of the Delaware Code (the General Corporation Law 
of the State of Delaware); or (iv) for any transaction from which the director 
derived an improper personal benefit. In the event that the Delaware General 
Corporation Law or any successor thereto is amended with respect to the 
permissible limits of directors' liability, this Article X shall be deemed to 
provide the fullest limitation on liability permitted under such amended 
statute. Any repeal or modification of 

<PAGE>

this Article X by the stockholders of the Corporation only shall be applied
prospectively, to the extent that such repeal or modification would, if applied
retrospectively, adversely affect any limitation on the personal liability of a
director of the Corporation existing immediately prior to such repeal or
modification.

                                   ARTICLE XI

                              RESERVATION OF RIGHTS

      The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Certificate of Incorporation, in the manner now or
hereafter prescribed by statute.

are filed with the minutes of proceedings of the board or such committee.

                  Section 24. Compensation. The directors may be paid their
expenses, if any, of attendance at each meeting of the board of directors and

provisions of the statutes or of the certificate of incorporation or of these

not be construed to require personal notice, but such notice may be given in
writing, by mail, addressed to such director or stockholder, at his address as
it appears on the records of the Corporation, with postage thereon prepaid, and
such notice shall be deemed to be given at the time when the same shall be
deposited in the United States mail. Notice may also be given by telegram,
express courier, or facsimile.

                  Section 28. Waiver of Notice. Whenever any notice is required
to be given under the provisions of the statutes or of the certificate of
incorporation or of these bylaws, a waiver thereof in writing, signed by the
person or persons entitled to said notice, whether before or after the time
stated therein, shall be deemed equivalent to notice. Attendance of a person at
a meeting of stockholders, directors, or members of a committee of directors,
shall constitute a waiver of notice of such meeting, except when the
stockholder, director or committee member attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders, directors, or members of a committee of directors need be
specified in any written waiver of notice unless so required by the certificate
of incorporation or these bylaws.

<PAGE>

classes of shares or different series within a class, the designations, relative

destroyed. When authorizing such issue of a new certificate, the board of
directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to give the Corporation a bond in
such sum as it may direct as indemnity against any claim that may be made
against the Corporation with respect to the certificate alleged to have been
lost, stolen or destroyed.

                  Section 44. Fixing Record Date. 

                  (a) In order that the Corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the board of directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors, and which record date shall
not be more than sixty nor less than ten days before the date of such meeting.
If no record is fixed by the board of directors, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders shall
be at the close of business on the day next preceding the day on which notice is
given, or, if notice is waived, at the close of business on the day next
preceding the next day on which the meeting is held. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; 


                                       9

<PAGE>

provided, however, that the board of directors may fix a new record date for the
adjourned meeting.

                  (b) In order that the Corporation may determine the
stockholders entitled to consent to corporate action in writing without a
meeting, the board of directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is adopted
by the board of directors, and which date shall not be more than ten days after
the date upon which the resolution fixing the record date is adopted by the
board of directors. If no record date has been fixed by the board of directors,
the record date for determining stockholders entitled to consent to corporate
action in writing without a meeting, when no prior action by the board of
directors is required by the General Corporation Law of Delaware, shall be the
first date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business or an officer or
agent of the Corporation having custody of the book in which proceedings of
meetings of stockholders are recorded. Delivery made to the Corporation's
registered office shall be by hand or by certified or registered mail, return
receipt requested. If no record date has been fixed by the board of directors
and prior action by the board of directors is required by the General
Corporation Law of Delaware, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting shall be at
the close of business on the day on which the board of directors adopts the
resolution taking such prior action.

                  (c) In order that the Corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock, or for the purpose of
any other lawful action, the board of directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty days
prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the board of directors adopts the resolution relating
thereto.

                  Section 45. Registered Stockholders. The Corporation shall be
entitled to treat the record holder of any shares of stock of the Corporation as
the owner thereof for all purposes, including all rights deriving from such
shares, and except as required by law shall not be bound to recognize any
equitable or other claim to, or interest in, such shares or rights deriving from
such shares, on the part of any other person, including, but without limiting
the generality thereof, a purchaser, assignee or transferee of such shares or
rights deriving from such shares, unless and until such purchaser, assignee,
transferee or other person becomes the record holder of such shares, whether or
not the Corporation shall have either actual or constructive notice of the
interest of such purchaser, assignee, transferee or other person. Any such
purchaser, assignee, transferee or other person shall not be entitled to receive
notice of the meetings of stockholders, to vote at such meetings, to examine a
complete list of the stockholders entitled to vote at meetings, or to own,
enjoy, and exercise any other property or rights deriving from such 



                                       10

shares against the Corporation, until such purchaser, assignee, transferee or
other person has become the record holder of such shares.

                                   ARTICLE VII

                  Section 47. Execution of Instruments. Contracts, deeds,

procedure for their execution.

                  Section 48. Checks and Drafts. The Corporation shall establish
a bank account for deposit of the funds of the Corporation and the drawing of

the chief operating officer of the Corporation. The appointment of additional
signatories of the bank account and the opening of additional bank accounts
shall require the approval of the board of directors.

directors shall adopt one, shall have inscribed thereon the name of the
Corporation, the year of its organization and the words "Corporate Seal,
Delaware." The seal may be used by causing it or a facsimile thereof to be

                  Section 50. Voting Shares in Other Corporations. In the
absence of other arrangements by the board of directors, shares of stock issued
by any other corporation and owned or controlled by this Corporation may be
voted at any stockholders' meeting of the other corporation by the chief
executive officer of this Corporation, if any, the president of this Corporation
or, if he or she is not present at the meeting, by the chief operating officer
of this Corporation, if any, or if so determined by the board of directors, by a
vice president of the Corporation designated by the board, and in the event that
none of the chief executive officer, the president, the chief operating officer
or such vice president are present at a meeting, the shares may be voted by such
person as the president and secretary of this Corporation shall by duly executed
proxy designate to represent this Corporation.

                                  ARTICLE VIII

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  Section 51. Definitions. As used in this article, the term
"person" means any past, present or future director or officer of the
Corporation or any subsidiary or operating division thereof.

                  Section 52. Indemnification Granted. The Corporation shall
indemnify, to the full extent and under the circumstances permitted by the
General 




                                       11

<PAGE>

Corporation Law of the State of Delaware in effect from time to time, any person
as defined above, made or threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such person is or
was a director or officer of the Corporation or a subsidiary or operating
division thereof, or is or was an employee or agent of the Corporation, or is or
was serving at the specific request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity, against costs, charges, expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person or on such person's behalf in connection with such
action, suit or proceeding and any appeal therefrom, if such person acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the Corporation, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe that his or her conduct
was unlawful. The termination of any action, suit, or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that such
conduct was unlawful.

                  Section 53. Requirements for Indemnification. The Corporation
shall indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action or suit by or in the right
of the Corporation to procure a judgment in its favor by reason of the fact that
such person is or was a director, officer, employee or agent of the corporation,
or a subsidiary thereof or a designated officer of an operating division of the
Corporation, or is or was serving at the specific request of the Corporation as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, or by reason of any action alleged to
have been taken or omitted in such capacity, against costs, charges and expenses
(including attorneys' fees) actually and reasonably incurred by such person or
on such person's behalf in connection with the defense or settlement of such
action or suit and any appeal therefrom, if such person acted in good faith and
in a manner that such person reasonably believed to be in or not opposed to the
best interests of the Corporation except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of such
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such costs, charges and expenses
which the Court of Chancery or such other court shall deem proper.

                  Section 54. Success on Merits of any Action. Notwithstanding
any other provision of this Article, to the extent that a director, officer,
employee or agent of the corporation or any subsidiary or operating division
thereof has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without 



                                       12

<PAGE>

prejudice, in defense of any action, suit or proceeding referred to in this
Article, or in defense of any claim, issue or matter therein, such person shall
be indemnified against all costs, charges and expenses (including attorneys'
fees) actually and reasonably incurred by such person or on such person's behalf
in connection therewith.

                  Section 55. Determination of Standard of Conduct. Any
indemnification under Sections 2 and 3 of this Article (unless ordered by a
court) shall be paid by the Corporation only after a determination has been made
(1) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (2) if
such quorum is not obtainable, or even if obtainable, a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or (3)
by the stockholders, that indemnification of the director, officer, employee or
agent is proper in the circumstances of the specific case because such person
has met the applicable standard of conduct set forth in Sections 2 and 3 of this
Article.

                  Section 56. Advance Payment; Representation by Corporation.

      Costs, charges and expenses (including attorneys' fees) incurred by a
person referred to in Sections 2 and 3 of this Article in defending a civil or
criminal action, suit or proceeding shall be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding; provided, however,
that the payment of such costs, charges and expenses incurred by a director or
officer in such capacity as officer or director (and not in any other capacity
and which service was or is rendered by such person while a director or officer)
in advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so advanced in the event that it shall ultimately
be determined that such director or officer is not entitled to be indemnified by
the Corporation as authorized in this Article. Such costs, charges and expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the board of directors deems appropriate. The Corporation
may, in the manner set forth above, and upon approval of such director, officer,
employee or agent, authorize the Corporation's counsel to represent such person,
in any action, suit or proceeding, whether or not the Corporation is a party to
such action, suit or proceeding.

                  Section 57. Procedure for Obtaining Indemnity. Any
indemnification under Sections 2, 3 and 4, or advance of costs, charges and
expenses under Section 6 of this Article, shall be made promptly, and in any
event within sixty (60) days, of the written notice of the director, officer,
employee or agent. The right to indemnification or advances as granted by this
Article shall be enforceable by the director, officer, employee or agent in any
court of competent jurisdiction if the Corporation denies such request, in whole
or in part, or if no disposition thereof is made within sixty (60) days. Such
person's costs and expenses incurred in connection with successfully
establishing a right to indemnification, in whole or in part, in any such action
shall also be indemnified by the Corporation. It shall be a defense to any such
action (other than an action brought to enforce a claim for the advance of
costs, charges and expenses under Section 6 of this Article where the required
undertaking, if any, has been received by the Corporation) that the claimant has
not met the standard of conduct set forth in Section 2 or 3 of this Article, 



                                       13

<PAGE>

but the burden of proving such defense shall be on the Corporation. Neither
failure of the Corporation (including its board of directors, its independent
legal counsel, and its stockholders) to have made a determination that
indemnification of the claimant is proper in the circumstances because such
person has met the applicable standard of conduct set forth in Section 2 or 3 of
this Article, nor the fact that there has been an actual determination by the
Corporation (including its board of directors, its independent legal counsel,
and its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

                  Section 58. Indemnification Not Exclusive. This right of
indemnification shall not be deemed exclusive of any other rights to which a
person indemnified herein may be entitled by law, agreement, vote of
stockholders or disinterested directors or otherwise, and shall continue as to a
person who has ceased to be a director, officer, designated officer, employee or
agent and shall inure to the benefit of the heirs, executors, administrators and
other legal representatives of such person. It is not intended that the
provisions of this article be applicable to, and they are not to be construed as
granting indemnity with respect to, matters as to which indemnification would be
in contravention of the laws of Delaware or of the United States of America,
whether as a matter of public policy or pursuant to statutory provision.

                  Section 59. Invalidity of Certain Provisions. If this Article
or any portion hereof shall be invalidated on any ground by any court of
competent jurisdiction, then the Corporation shall nevertheless indemnify each
director, officer, employee and agent of the Corporation or any subsidiary or
operating division thereof as to costs, charges and expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement with respect
to any action, suit or proceeding, whether civil, criminal, administrative or
investigative, including any action by or in the right of the Corporation, to
the full extent permitted by any applicable portion of this Article that shall
not have been invalidated and to the full extent permitted by applicable law.

                  Section 60. Miscellaneous. The board of directors may also on
behalf of the Corporation grant indemnification to any individual other than a
person defined herein to such extent and in such manner as the board in its sole
discretion may from time to time and at any time determine.

                                   ARTICLE IX

                                    AMENDMENT

      These bylaws may be amended or repealed by the affirmative vote of a
majority of the directors then in office.

determination means the ratio of (i) the aggregate amount of Cash Flow for the
period of the most recent four consecutive fiscal quarters to (ii) Consolidated
Interest Expense for such four fiscal quarters; provided, however, to the extent
relevant to the calculation for any period, Cash Flow and Consolidated Interest
Expense shall be calculated using the pro forma consolidated statements of
operations of the Company included in the Offering Circular, which pro forma
statements of operations shall give effect to the Transactions (as defined
therein) as if they occurred at the beginning of the relevant period; provided,
further, however, that (1) if the Company or any Restricted Subsidiary has
issued any Indebtedness since the beginning of such period and on or prior to
the relevant date of determination that remains outstanding or if the
transaction giving rise to the need to calculate the Consolidated Cash Flow
Coverage Ratio is an issuance of Indebtedness, or both, Cash Flow and
Consolidated Interest Expense for such period shall be calculated after giving
effect on a pro forma basis to such Indebtedness as if such Indebtedness had
been issued on the first day of such period and the discharge of any other
Indebtedness repaid, repurchased, defeased or otherwise discharged with the
proceeds of such new Indebtedness as if such discharge had occurred on the first
day of such period, (2) if since the beginning of such period and on or prior to
the relevant date of determination the Company or any Restricted Subsidiary
shall have made any Asset Disposition, the Cash Flow 


                                       6

positive) directly attributable to the assets which are the subject of such
Asset Disposition for such period, or increased by an amount equal to the Cash
Flow (if negative), directly attributable thereto for such period, and
Consolidated Interest Expense for such period shall be reduced by an amount
equal to the Consolidated Interest Expense directly attributable to any
Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased,
defeased or otherwise discharged with respect to the Company and its continuing
Restricted Subsidiaries in connection with such Asset Dispositions for such
period (or, if the Capital Stock of any Restricted Subsidiary is sold, the
Consolidated Interest Expense for such period directly attributable to the
Indebtedness of such Restricted Subsidiary to the extent the Company and its
continuing Restricted Subsidiaries are no longer liable for such Indebtedness
after such sale), (3) to the extent not duplicative with (2) above, if since the
beginning of such period and on or prior to the relevant date of determination
any Emissions Contract ceased or ceases to be in effect, the Cash Flow for such
period shall be reduced by an amount equal to the cash Flow (if positive)
directly attributable thereto for such period, or increased by an amount equal
to the Cash Flow (if negative) directly attributable thereto for such period and
Consolidated Interest Expense for such period shall be reduced by an amount
equal to the Consolidated Interest Expense directly attributable to any
Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased,
defeased or otherwise discharged with respect to the Company and its Restricted
Subsidiaries with the proceeds of any termination fee or similar payment
received by the Company or a Restricted Subsidiary as a result of the cessation
of such Emissions Contract, (4) if since the beginning of such period and on or
prior to the relevant date of determination the Company or any Restricted
Subsidiary (by merger or otherwise) shall have made an Investment in any
Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or
an acquisition of assets (including Capital Stock of a Subsidiary), including
any acquisition of assets occurring in connection with a transaction causing a
calculation to be made hereunder, Cash Flow and Consolidated Interest Expense
for such period shall be calculated after giving pro forma effect thereto
(including the issuance of any Indebtedness and including pro forma cost
reductions, in each case as calculated in accordance with the applicable
accounting requirements of Rule 11-02 of Regulation S-X under the Securities Act
or any successor provision relating to the preparation of pro forma financial
statements (it being understood that all cost reductions set forth in Note (3)
to the unaudited pro forma consolidated statements included in the Offering
Circular shall be deemed to be calculated on a basis consistent with such
requirements)) as if such Investment or acquisition occurred on the first day of
such period, and (5) if since the beginning of such period and on or prior to
the relevant date of determination any Person (that subsequently became a
Restricted Subsidiary or was merged with or into the Company or any Restricted
Subsidiary since the beginning of such period) shall have made any Asset
Disposition or any Investment, or any Emissions Contract entered into by such
Person shall cease to be in effect, that would have required an adjustment
pursuant to clause (2), (3) or (4) above if made by, or if in respect of, the
Company or a Restricted Subsidiary during such period, Cash Flow and
Consolidated Interest Expense for such period shall be calculated after giving
pro forma effect thereto (including pro forma cost reductions, in each case as
calculated in accordance with the applicable accounting requirements of Rule
11-02 of Regulation S-X under the Securities Act or any successor provision
relating to the preparation of pro forma financial statements (it being
understood that all cost reductions set forth in Note (3) to the unaudited pro
forma consolidated statements 


                                       7
<PAGE>

included in the Offering Circular shall be deemed to be calculated on a basis
consistent with such requirements)) as if such Asset Disposition, Investment or
cessation of such Emissions Contract occurred on the first day of such period.
For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto, and
the amount of Consolidated Interest Expense associated with any Indebtedness
issued in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting officer of the Company.
If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest of such Indebtedness shall be calculated as if the
rate in effect on the date of determination had been the applicable rate for the
entire period (taking into account any Interest Rate Protection Agreement
applicable to such Indebtedness if such Interest Rate Protection Agreement has a
remaining term in excess of 12 months). For purposes of this definition,
whenever pro forma effect is to be given to any Indebtedness Incurred pursuant
to a revolving credit facility the amount outstanding under such Indebtedness
shall be equal to the average of the amount outstanding during the period
commencing on the first day of the first of the four most recent fiscal quarters
for which financial statements are available and ending on the date of
determination.

            "Consolidated Interest Expense" means, for any period, the total
interest expense of the Company and its consolidated Restricted Subsidiaries
determined in accordance with GAAP, plus, to the extent not included in such
interest expense but Incurred by the Company or its Restricted Subsidiaries, (i)

discount and debt issuance cost (other than those debt discounts and debt
issuance costs incurred on the Issue Date), (iii) capitalized interest, (iv)
original issue discount and non-cash interest payments or accruals, (v)
commissions, discounts and other fees and charges owed with respect to letters
of credit and bankers' acceptance financing, (vi) net costs under Hedging
Obligations (including amortization of fees), (vii) dividends in respect of all
Disqualified Stock or Preferred Stock held by Persons other than the Company, a
Subsidiary Guarantor or a Wholly Owned Subsidiary, (viii) interest Incurred in
connection with investments in discontinued operations, (ix) the interest
portion of any deferred payment obligations, (x) the cash contributions to any
employee stock ownership plan or similar trust to the extent such contributions
are used by such plan or trust to pay interest or fees to any Person (other than
the Company) in connection with Indebtedness Incurred by such plan or trust and
(xi) imputed interest expense associated with any Attributable Debt. For
purposes of this definition, interest expense attributable to any Indebtedness
represented by the Guarantee by such Person or a Subsidiary of such Person of an
obligation of another Person shall be deemed to be the interest expense
attributable to the Indebtedness Guaranteed.

            "Consolidated Net Income" means, for any period, the net income or
loss of the Company and its consolidated Subsidiaries determined in accordance
with GAAP; provided, however, that there shall not be included in such
Consolidated Net Income:

            (i) any net income of any Person if such Person is not a Restricted
      Subsidiary or that is accounted for by the equity method of accounting,
      except that (A) the Company's equity in the net income of any such Person
      for such period shall be included in such Consolidated Net Income up to
      the aggregate amount of cash actually 


                                       8
<PAGE>

      distributed by such Person during such period to the Company or a
      Restricted Subsidiary as a dividend or other distribution (subject, in the
      case of a dividend or other distribution to a Restricted Subsidiary, to
      the limitations contained in clause (iii) below) and (B) the Company's
      equity in a net loss of any such Person for such period shall be included
      in determining such Consolidated Net Income;

            (ii) any net income of any Person acquired by the Company or a
      Subsidiary in a pooling of interests transaction for any period prior to
      the date of such acquisition;

            (iii) any net income of any Restricted Subsidiary (other than
      Envirotest Systems Corp. and Environmental Systems Products, Inc., in each
      case, solely for the period prior to the Issue Date) if such Restricted
      Subsidiary is subject to restrictions (other than restrictions under the
      Credit Facility, this Indenture or the indenture governing the Senior
      Discount Notes), directly or indirectly, on the payment of dividends or

the Company shall otherwise comply with TIA Section  312(a).

            SECTION 2.06. [Intentionally Omitted]

            SECTION 2.07. Replacement Notes.

            If a mutilated Note is surrendered to the Trustee or if the Holder
of a Note claims that the Note has been lost, destroyed or wrongfully taken,
subject to the terms of the next succeeding sentence, the Company shall issue
and the Trustee shall authenticate a replacement Note if the Trustee's
reasonable requirements for replacement Notes are met. If required by the
Trustee or the Company, such Holder must provide an affidavit of lost
certificate and an indemnity bond or other indemnity, sufficient in the judgment
of both the Company and the Trustee, to protect the Company, the Trustee, any
Agent or any Authenticating Agent from any loss which any of them may suffer if
a Note is replaced. The Company and the Trustee may charge such Holder for their
out-of-pocket expenses in replacing a Note, including reasonable fees and
expenses of counsel, and for any tax that may be imposed in replacing such
Notes. Every replacement Note shall constitute an additional obligation of the
Company.

            SECTION 2.08. Outstanding Notes.

            Notes outstanding at any time are all the Notes 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. Subject
to the provisions of Section 2.09, a Note does not cease to be outstanding
because the Company or any of its Affiliates holds the Note.

            If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by
a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender
of such Note and replacement thereof pursuant to Section 2.07.

            Except as otherwise provided in Article Eight of this Indenture, if
on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal
Tender or U.S. Government Obligations sufficient to pay all of the principal and
interest due on the Notes payable on that date and is not prohibited from paying
such money to the Holders thereof pursuant to the terms of this Indenture, then
on and after that date such Notes cease to be 


                                       28
<PAGE>

outstanding and interest on them ceases to accrue.

            SECTION 2.09. Treasury Notes.

            In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, waiver, consent or notice, Notes owned
by the Company or any of its Affiliates shall be considered as though they are
not outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver, consent or notice,
only Notes which a Trust Officer of the Trustee actually knows are so owned
shall be so considered.

            SECTION 2.10. Temporary Notes.

            Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate upon receipt of a written order of the Company pursuant to Section
2.02 definitive Notes in exchange for, and upon surrender of, temporary Notes.
Until so exchanged, the temporary Notes shall in all respects be entitled to the
same benefits under this Indenture as definitive Notes authenticated and
delivered hereunder.

            SECTION 2.11. Cancellation.

            The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment. The Trustee, or
at the direction of the Trustee, the Registrar or the Paying Agent, and no one
else, shall cancel and, at the written direction of the Company, shall dispose
of all Notes surrendered for transfer, exchange, payment or cancellation.
Subject to Section 2.07, the Company may not issue new Notes to replace Notes
that it has paid or delivered to the Trustee for cancellation. If the Company
shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Notes 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 Notes
(without regard to any grace period therefor), it shall pay the defaulted
interest, plus (to the extent lawful) any interest payable on the defaulted
interest to the Persons who are Holders on a subsequent special record date,
which date shall be the fifteenth day 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 the subsequent special
record date, the 


                                       29
<PAGE>

Company shall mail to each Holder, as of a recent date selected by the Company,
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 Notes may use "CUSIP" numbers, and if so,
the Trustee shall use such CUSIP numbers in notices of redemption or exchange as
a convenience to Holders; provided that no representation is hereby deemed to be
made by the Trustee as to the correctness or accuracy of such CUSIP numbers
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes. The Company shall
promptly notify the Trustee of any change in a CUSIP number.

            SECTION 2.14. Deposit of Moneys.

            Prior to 9:00 a.m. New York City time on each Interest Payment Date
and on the Maturity Date, the Company shall deposit with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity 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 or Maturity Date, as the case may be.

                                  ARTICLE THREE

                                   REDEMPTION

            SECTION 3.01. Notices to Trustee.

            If the Company elects to redeem Notes pursuant to Section 3.07 of
this Indenture and Paragraph 6 of the Notes, it shall notify the Trustee and the
Paying Agent in writing of the Redemption Date and the principal amount of the
Notes to be redeemed.

            The Company shall give each notice provided for in this Section 3.01
at least 60 days before the Redemption Date (unless a shorter notice period
shall be satisfactory to the Trustee, as evidenced in a writing signed on behalf
of the Trustee), together with an Officers' Certificate stating that such
redemption shall comply with the conditions contained herein and in the Notes.

            SECTION 3.02. Selection of Notes To Be Redeemed.

            If fewer than all of the Notes are to be redeemed, selection of the
Notes to be redeemed shall be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not then listed on a national securities
exchange by the Trustee, on a pro rata basis, by lot or in such other fair and
reasonable manner chosen at the discretion of the Trustee; provided, however,


                                       30
<PAGE>

that if a partial redemption is made with the proceeds of a Public Equity
Offering, selection of the Notes or portion thereof for redemption shall be made
by the Trustee only on a pro rata basis, unless such method is otherwise
prohibited. The Company shall promptly notify the Trustee and the Paying Agent
in writing of the date of listing and the name of the securities exchange if and
when the Notes are listed on a principal national securities exchange. The
Trustee shall make the selection from the Notes outstanding and not previously
called for redemption and shall promptly notify the Company in writing of the
Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes in denominations
of $1,000 may be redeemed only in whole. The Trustee may select for redemption
portions (equal to $1,000 or any integral multiple thereof) of the principal of
Notes that have denominations larger than $1,000. Provisions of this Indenture
that apply to Notes called for redemption also apply to portions of Notes called
for redemption.

            SECTION 3.03. Notice of Redemption.

            At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail or cause to be mailed a notice of redemption by first
class mail, postage prepaid, to each Holder whose Notes are to be redeemed, with
a copy to the Trustee and any Paying Agent. At the Company's written request no
less than 35 days prior to the Redemption Date (or such shorter period as may be
acceptable to the Trustee), the Trustee shall mail or cause to be mailed the
notice of redemption in the Company's name and at the Company's expense.

            Each notice for redemption shall identify the Notes 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) the subparagraph of the Notes pursuant to which such redemption
      is being made;

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

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


                                       31
<PAGE>

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

            (8) if fewer than all the Notes are to be redeemed, the aggregate
      principal amount of Notes to be redeemed and the aggregate principal
      amount of Notes to be outstanding after such partial redemption and, if
      the redemption is not made pro rata, the identification of the particular
      Notes (or portion thereof) to be redeemed; and

            (9) that no representation is made as to the correctness or accuracy
      of the CUSIP number, if any, listed in such notice or printed on the
      Notes.

            SECTION 3.04. Effect of Notice of Redemption.

            Once notice of redemption is mailed in accordance with Section 3.03,
Notes 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 Notes called for redemption shall be paid at the
Redemption Price and the amount of accrued interest payable thereon, provided
that if a Note is redeemed on or after a Record Date for an interest payment but
on or prior to the related Interest Payment Date, then any accrued and unpaid
interest shall be paid to the Holder of record at the close of business on such
Record Date. Failure to give notice or any defect in the notice to any Holder
shall not affect the validity of the notice to any other Holder.

            Except in connection with a defeasance pursuant to Section 8.02 of
this Indenture, at any time prior to the mailing of a notice of redemption to
the Holders pursuant to Section 3.03, the Company may withdraw, revoke or
rescind any notice of redemption delivered to the Trustee without any continuing
obligation to redeem the Notes.

            SECTION 3.05. Deposit of Redemption Price.

            On or before 9:00 a.m. New York City 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 Notes to be
redeemed on that date (other than Notes or portions of Notes called for
redemption which have been delivered by the Company to the Trustee for
cancellation). The Paying Agent shall promptly return to the Company any U.S.
Legal Tender so deposited which is not required for that purpose, except with
respect to monies owed as obligations to the Trustee pursuant to Article Seven.

            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 Notes to be redeemed shall cease to accrue on
and after the applicable Redemption Date, whether or not such Notes are
presented for payment.

            SECTION 3.06. Notes Redeemed in Part.


                                       32
<PAGE>

            Upon surrender of a Note that is to be redeemed in part, the Company
shall execute and the Trustee shall authenticate for the Holder a new Note or
Notes equal in principal amount to the unredeemed portion of the Note
surrendered.

            SECTION 3.07. Optional Redemption.

            (a) Except as set forth in the clause (b) below, the Notes shall not
be redeemable at the option of the Company prior to October 31, 2003.
Thereafter, the Notes shall be redeemable, at the Company's option, in whole or
in part, at any time or from time to time, upon not less than 30 nor more than
60 days' prior notice mailed by first class mail to each Holder's registered
address at the following redemption prices (expressed in percentages of
principal amount), plus accrued and unpaid interest to the Redemption Date
(subject to the right of Holders of record on the relevant Record Date to
receive interest due on the relevant Interest Payment Date), if redeemed during
the 12-month period commencing on October 31 of the years set forth below:

            2006 and thereafter.................................        100.000%

</TABLE>

            (b) In addition, at any time and from time to time prior to October
31, 2001, the Company may redeem in the aggregate up to 35% of the original
principal amount of the Notes with the Net Cash Proceeds of one or more Public
Equity Offerings, at a redemption price (expressed as a percentage of principal
amount) of 113% plus accrued interest to the Redemption Date (subject to the
right of Holders of record on the relevant Record Date to receive interest due
on the relevant Interest Payment Date); provided, however, that at least 65% of
the aggregate principal amount of the Notes originally outstanding must remain
outstanding after each such redemption.

            In order to effect the foregoing redemption with the proceeds of any
Public Equity Offering, the Company shall make such redemption not more than 120
days after the consummation of any such Public Equity Offering.

                                    COVENANTS

            SECTION 4.01. Payment of Notes.

            The Company shall pay or cause to be paid the principal of and
interest on the


                                       33
<PAGE>

Notes on the dates and in the manner provided in the Notes and in this
Indenture. An installment of principal of or interest on the Notes shall be
considered paid on the date it is due if the Trustee or Paying Agent (other than
the Company or an Affiliate of the Company) holds on that date U.S. Legal Tender
designated for and sufficient to pay the installment in full and is not
prohibited from paying such money to the Holders pursuant to the terms of this
Indenture.

            Notwithstanding anything to the contrary contained in this
Indenture, the Company or Paying Agent may, to the extent it is required to do
so by law, deduct or withhold income or other similar taxes imposed by the
United States of America from principal or interest payments hereunder.

            SECTION 4.02. Maintenance of Office or Agency.

            The Company shall maintain 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.

            SECTION 4.03. Corporate Existence.

            Except as otherwise permitted by Article Five and Section 4.16, the
Company shall do or cause to be done, at its own cost and expense, all things
necessary to preserve and keep in full force and effect its corporate existence
and the corporate existence of each of its Restricted Subsidiaries in accordance
with the respective organizational documents of each of them (as the same may be
amended from time to time) and the material rights (charter and statutory) and
franchises of the Company and each such Restricted Subsidiary; provided,
however, that neither the Company nor any Restricted Subsidiary shall be
required to preserve any right or franchise if the Board of Directors of the
Company or the Restricted Subsidiary, as the case may be, shall reasonably
determine that the preservation thereof is no longer desirable in the conduct of
the business of such entity; provided further that no Restricted Subsidiary
shall be required to maintain its corporate existence if the Board of Directors
and the board of directors of such Restricted Subsidiary both reasonably
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Restricted Subsidiaries, taken as a whole,
and cessation of such corporate existence is not disadvantageous in any material
respect to the Holders.

            SECTION 4.04. Payment of Taxes and Other Claims.

            The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (i) all material taxes,
assessments and governmental charges (including withholding taxes and any
penalties, interest and additions to taxes) levied or imposed upon it or any of
its Restricted Subsidiaries or properties of it or any of its Restricted
Subsidiaries (other than those taxes, assessments and governmental charges the
nonpayment of 


                                       34
<PAGE>

which would not have a material adverse effect upon the business, financial
condition or results of operations of the Company and its Restricted
Subsidiaries, taken as a whole) and (ii) all lawful claims for labor, materials
and supplies which are for an amount in excess of $1,000,000 and remain unpaid
for at least 90 days after the due date thereof and which if unpaid, might by
law become a Lien other than a Permitted Lien upon the property of it or any of
its Subsidiaries; provided, however, that the Company shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings properly instituted and diligently
conducted for which adequate reserves, to the extent required under and in
accordance with GAAP, have been taken.

            SECTION 4.05. Maintenance of Properties and Insurance.

            (a) The Company shall, and shall cause each of its Restricted
Subsidiaries to, maintain its material properties in good working order and
condition (subject to ordinary wear and tear) and make all necessary repairs,
renewals, replacements, additions, betterments and improvements thereto and
actively conduct and carry on its business; provided, however, that nothing in
this Section 4.05 shall prevent the Company or any of its Restricted
Subsidiaries from discontinuing the operation and maintenance of any of its
properties, if such discontinuance is, in the reasonable good faith judgment of
the Board of Directors of the Company or the Restricted Subsidiary, as the case
may be, desirable in the conduct of the business of the Company and its
Restricted Subsidiaries, taken as a whole, and is not disadvantageous in any
material respect to the Holders.

            (b) The Company shall provide or cause to be provided, for itself
and each of its Restricted Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the good faith
judgment of the Board of Directors of the Company, are adequate and appropriate
for the conduct of the business of the Company and such Restricted Subsidiaries
in a prudent manner, with reputable insurers or with the government of the
United States of America or an agency or instrumentality thereof, in such
amounts, with such deductibles, and by such methods as shall be customary, in
the reasonable good faith judgment of the Board of Directors of the Company, for
companies similarly situated in the industry.

            SECTION 4.06. Compliance Certificate; Notice of Default.

            (a) The Company shall deliver to the Trustee, within 120 days after
the end of the Company's fiscal year, an Officers' Certificate stating that a
review of its activities and the activities of its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers, one of whom must be the Company's chief executive or chief financial
officer with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture and further
stating, as to each such Officer signing such certificate, that to the best of
such Officer's knowledge, based on such review, the Company during such
preceding fiscal year has kept, observed, performed and fulfilled each and every
such covenant contained in this Indenture and no Default or Event of Default
occurred during such year and at the date of such certificate there is no
Default or


                                       35
<PAGE>

Event of Default that has occurred and is continuing or, if such signers do know
of such Default or Event of Default, the certificate shall describe the Default
or Event of Default and its status with particularity. The Officers' Certificate
shall also notify the Trustee should the Company elect to change the manner in
which it fixes its fiscal year end.

            (b) So long as not contrary to the then-current recommendations of
the American Institute of Certified Public Accountants, the annual financial
statements delivered pursuant to Section 4.08 shall be accompanied by a written
report of the Company's independent accountants (who shall be a firm of
established national reputation) that in conducting their audit of such
financial statements nothing has come to their attention that would lead them to
believe that the Company has violated any provisions of Article Four or Five of
this Indenture or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable directly or indirectly to any Person for any failure to obtain
knowledge of any such violation.

            (c) (i) If any Default or Event of Default has occurred and is
continuing or (ii) if any Holder seeks to exercise any remedy hereunder with
respect to a claimed Default under this Indenture or the Notes, the Company
shall deliver to the Trustee, at its address set forth in Section 13.02 hereof,
by registered or certified mail or by telegram, telex or facsimile transmission
followed by hard copy by registered or certified mail an Officers' Certificate
specifying such event, notice or other action within five Business Days' of its
becoming aware of such occurrence.

            SECTION 4.07. Compliance with Laws.

            The Company shall comply, and shall cause each of its Restricted
Subsidiaries to comply, with all applicable statutes, rules, regulations, orders
and restrictions of the United States of America, all states and municipalities
thereof, and of any governmental department, commission, board, regulatory
authority, bureau, agency and instrumentality of the foregoing, in respect of
the conduct of their respective businesses and the ownership of their respective
properties, except for such noncompliances as are not in the aggregate
reasonably likely to have a material adverse effect on the financial condition
or results of operations of the Company and its Restricted Subsidiaries, taken
as a whole.

            SECTION 4.08. SEC Reports.

            (a) So long as the Notes are outstanding, whether or not required by
the rules and regulations of the SEC, beginning with the year ended December 31,
1998, the Company (at its own expense) shall furnish to the Trustee and all
Holders of Notes (i) all quarterly and annual financial information that would
be required to be contained in a filing with the SEC on Forms 10-Q and 10-K, as
applicable, if the Company were required to file such Forms, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and, with respect to the annual information only, a report thereon
by the Company's certified independent accountants and (ii) all current reports
that would be required to be filed with the SEC on Form 8-K if the Company were
required to file such reports, in each case within the time periods specified in
the SEC's rules and regulations; 


                                       36
<PAGE>

provided that the foregoing shall not require the Company to furnish separate
financial results of its Subsidiaries. The Company shall make such information
available to securities analysts and prospective investors upon request, and,
for so long as any Notes remain outstanding, shall furnish to the Trustee,
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

            (b) The Company shall provide to any Holder any information
reasonably requested by such Holder concerning the Company (including financial
statements) necessary in order to permit such Holder to sell or transfer Notes
in compliance with Rule 144A under the Securities Act.

            SECTION 4.09. Waiver of Stay, Extension or Usury Laws.

            The Company covenants (to the extent that it may lawfully do so)
that it shall 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 from paying
all or any portion of the principal of or interest on the Notes 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) the Company hereby expressly waives all benefit or
advantage of any such law, and covenants that it shall not hinder, delay or
impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had

Company and its Subsidiaries to the appropriate taxing authorities if they filed
separate tax returns to the extent that Holdco has an obligation to pay such tax
liabilities relating to the operations, assets or capital of the Company and its
Subsidiaries, provided that any such payment shall either be used by Holdco to
pay such tax liabilities within 30 days of receipt of such payment or refunded
to the payee; provided, further, that such payments shall be excluded from the
calculation of the amount of Restricted Payments available to be made referred
to in clause (a)(3) of this Section 4.10; and (7) payments to Holdco (i) to

deducted in the calculation of the amount of Restricted Payments available to be
made referred to in clause (a)(3) of this Section 4.10.

            SECTION 4.11. Limitation on Restrictions on Distributions from
                          Restricted Subsidiaries.

            The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on its Capital
Stock or with respect to any other interest or participation in, or measured by,
its profits to the Company or a Restricted Subsidiary or pay any Indebtedness or
other obligation owed to the Company or a Restricted Subsidiary, (ii) make any
loans or advances to the Company or any other Restricted Subsidiary or (iii)
transfer any of its property or assets to the Company or any other Restricted
Subsidiary, except for such encumbrances or restrictions existing under or by
reason of (a) (x) this Indenture, the Credit Facility or the indenture governing
the Senior Discount Notes, in each case as in effect on the Issue Date, and any
amendments, restatements, renewals, replacements or refinancings thereof;
provided, however, that any such amendments, restatements, renewals,
replacements or refinancings to or under the Credit Facility or the indenture
governing the Senior Discount Notes are not materially more restrictive, when
taken as a whole, with respect to such dividend and other payment restrictions,
to the Company or any Restricted Subsidiary than those contained in the Credit
Facility or such indenture, as the case may be, (or, if more restrictive, than
those contained in this Indenture) immediately prior to any such amendment,
restatement, renewal, replacement or refinancing, or (y) the indenture relating
to any Public Debt issued after the date hereof, which encumbrances or
restrictions are not materially more restrictive, when taken as a whole, with
respect to such dividend and other payment restrictions, to the 


                                       39
<PAGE>

Company or any Restricted Subsidiary than those contained in this Indenture, (b)
applicable law, (c) any instrument governing Indebtedness or Capital Stock of an
Acquired Person acquired by the Company or any of its Restricted Subsidiaries as
in effect at the time of such acquisition (except to the extent such
Indebtedness was incurred in connection with or in contemplation of such
acquisition or in violation of Section 4.13; provided, however, that (1) such
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Acquired Person, and (2) the consolidated net income of
such Acquired Person for any period prior to such acquisition shall not be taken
into account in determining whether such acquisition was permitted by the terms
of this Indenture, (d) customary non-assignment provisions in leases or other
agreements entered into the ordinary course of business, (e) Purchase Money
Indebtedness for property acquired in the ordinary course of business that only
impose restrictions on the property so acquired, (f) an agreement for the sale
or disposition of the Capital Stock or assets of such Restricted Subsidiary;
provided, however, that such restriction is only applicable to such Restricted
Subsidiary or assets, as applicable, and such sale or disposition otherwise is
permitted under Section 4.17; provided, further, however, that such restriction
or encumbrance shall be effective only for a period from the execution and
delivery of such agreement through a termination date not later than 180 days
after such execution and delivery, or (g) Refinancing Indebtedness permitted
under this Indenture; provided, however, that the restrictions contained in the
agreements governing such Refinancing Indebtedness are no more restrictive in
the aggregate than those contained in the agreements governing the Indebtedness
being refinanced immediately prior to such refinancing. Notwithstanding the
foregoing, neither (a) customary provisions restricting subletting or assignment
of any lease entered into in the ordinary course of business, nor (b) Liens
permitted under this Indenture, shall in and of themselves be considered a
restriction on the ability of the applicable Restricted Subsidiary to transfer
such agreements or assets, as the case may be.

            SECTION 4.12. Limitation on Affiliate Transactions.

            (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, conduct any business or enter into any
transaction or series of similar transactions (including the purchase, sale,
lease, transfer or other disposition or exchange of any asset or property or the
rendering of any service) with any Affiliate of the Company (other than the
Company or any Wholly Owned Subsidiary of the Company or any employee stock
ownership plan or similar trust for the benefit of the Company's or a Restricted
Subsidiary's employees) unless the terms of such business, transaction or series
of transactions are (i) no less favorable to the Company or such Restricted
Subsidiary as terms that would be obtainable at the time for a comparable
transaction or series of similar transactions in arms' length dealings with an
unrelated third Person and (ii) in the event that such transaction involves an
aggregate amount in excess of $5.0 million, a majority of the disinterested
members of the Board of Directors have, by resolution, determined in good faith
that such business or transaction or series of transactions meets the criteria
set forth in (i) above and have approved the transaction; provided, however,
that if such transaction involves an amount in excess of $10.0 million, the
Company shall also obtain from a nationally recognized independent investment
banking firm, accounting firm or appraisal firm with experience in evaluating
the terms and conditions of the type of business or transaction an opinion that
such transaction is 


                                       40
<PAGE>

fair from a financial point of view to the Company or its Restricted Subsidiary,
as the case may be.

            (b) The provisions of clause (a) of this Section 4.12 shall not
prohibit (i) any Restricted Payment permitted to be made pursuant to Section
4.10 or any payment or transaction specifically excepted from the definition of
Restricted Payment, (ii) any 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 entered into in
the ordinary course of business and approved by a majority of the entire Board
of Directors or by a majority of the disinterested members of the Board of
Directors or a majority of the entire board of directors or by a majority of the
disinterested members of the board of directors of the relevant Restricted
Subsidiary, (iii) the grant of stock options or similar rights to employees and
directors pursuant to plans approved by a majority of the entire Board of
Directors or by a majority of the disinterested members of the Board of
Directors or a majority of the entire board of directors or by a majority of the
disinterested members of the board of directors of the relevant Restricted
Subsidiary, (iv) loans or advances to officers, directors or employees in the
ordinary course of business which, except with respect to ordinary travel
expenses and advances, have been approved by the Board of Directors, (v) the
payment of reasonable fees to directors of Holdco, the Company and the
Subsidiaries who are not employees of Holdco, the Company or the Subsidiaries
for rendering of services (including attending meetings of the board of
directors) as a director, (vi) any Affiliate transaction between the Company and
a Subsidiary Guarantor, between Subsidiary Guarantors, or between Restricted
Subsidiaries which are each not Subsidiary Guarantors, (vii) indemnification or
insurance provided to officers or directors of Holdco, the Company or any
Subsidiary of the Company approved in good faith by the Board of Directors;
(viii) payment of compensation and benefits to directors, officers and employees
of the Company and Subsidiaries of the Company approved in good faith by the
Board of Directors; (ix) payment of a management or similar fee by Holdco, the
Company or any Restricted Subsidiary to Alchemy Partners (or a Person designated
by Alchemy Partners) in an amount, together with all other such payments made by
the Company and Restricted Subsidiaries, not to exceed $1.0 million per year (or
the equivalent thereof in another currency) plus reasonable out
of-pocket-expenses; (x) loans made to officers of the Company or its
Subsidiaries in an aggregate amount not to exceed $4.5 million outstanding at
any time solely for the purpose of reimbursing such officers for the amount of
income taxes payable by such officers in connection with shares of Capital Stock
of Holdco issued to such officers, which shares are pledged to the Company or
the Subsidiary making such loans, and (xi) the Permitted Investment contemplated
by clause (xii) of the definition of Permitted Investment.

            SECTION 4.13. Limitation on Indebtedness.

            (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, Incur, directly or indirectly, any Indebtedness (including
Acquired Indebtedness); provided, however, that the Company or any Subsidiary
Guarantor shall be permitted to Incur such Indebtedness if, on the date of such
Incurrence, and after giving pro forma effect thereto, (i) no Default or Event
of Default shall have occurred and be continuing or would occur and (ii) the
Consolidated Cash Flow Coverage Ratio at the date of such Incurrence exceeds
2.10 to 1.0 


                                       41
<PAGE>

if such Indebtedness is Incurred prior to October 31, 1999, and 2.35 to 1 if
such Indebtedness is Incurred thereafter.

            (b) Notwithstanding clause (a) of this Section 4.13, the Company and
any Restricted Subsidiary (other than a Restricted Subsidiary that is not a
Subsidiary Guarantor in the cases of clauses (i) and (xiii) below) may Incur the
following Indebtedness: (i) Indebtedness Incurred pursuant to the Credit
Facility not to exceed $435 million in aggregate principal amount outstanding at
any time, less the aggregate amount of all mandatory payments applied to
permanently reduce the commitments with respect to such Indebtedness, including
but not limited to reductions pursuant to clause (a) of Section 4.17; (ii)
Indebtedness of the Company to a Restricted Subsidiary; provided that any such
Indebtedness is subordinated in right of payment to the Notes; provided,
further, that any subsequent issuance, sale, transfer or other disposition of
any Capital Stock (including by consolidation or merger) or other event
(including the designation of a Restricted Subsidiary as an Unrestricted
Subsidiary under Section 4.20) which results in such Restricted Subsidiary
ceasing to be a Restricted Subsidiary or any subsequent transfer or other
disposition of any such Indebtedness (except to the Company or another
Restricted Subsidiary) shall be deemed, in each case, to be an Incurrence of
such Indebtedness by the issuer thereof at the time of any such issuance, sale,
transfer or other disposition, as the case may be; (iii) Indebtedness of a
Restricted Subsidiary to the Company or another Restricted Subsidiary; provided
that (x) if a Subsidiary Guarantor Incurs such Indebtedness to a Restricted
Subsidiary that is not a Subsidiary Guarantor, such Indebtedness is subordinated
in right of payment to the Subsidiary Guarantee of such Subsidiary Guarantor;
and (y) if a Restricted Subsidiary that is not a Subsidiary Guarantor Incurs
such Indebtedness to the Company or a Restricted Subsidiary that is a Subsidiary
Guarantor, the Incurrence of such Indebtedness constitutes a Restricted
Investment for the purposes of Section 4.10; provided, further, that any
subsequent issuance, sale, transfer or other disposition of any Capital Stock
(including by consolidation or merger) of any Restricted Subsidiary to which
such Indebtedness is owed or any other event (including the designation of a
Restricted Subsidiary as an Unrestricted Subsidiary under Section 4.20) which
results in such Restricted Subsidiary ceasing to be a Restricted Subsidiary or
any subsequent transfer or other disposition of any such Indebtedness (except to
the Company or another Restricted Subsidiary that is a Subsidiary Guarantor)
shall be deemed, in each case, to be an Incurrence of such Indebtedness by the
issuer thereof at the time of any such issuance, sale, transfer or other
disposition, as the case may be; (iv) the Notes and the Subsidiary Guarantees;
(v) Indebtedness (other than Indebtedness described in clause (i), (ii), (iii)
or (iv) above) outstanding on the Issue Date; (vi) any Refinancing Indebtedness
in respect of Indebtedness Incurred pursuant to paragraph (a) of this Section
4.13 or pursuant to clause (iv) or (v) of this clause (b) or this clause (vi);
(vii) obligations of the Company or such Restricted Subsidiary pursuant to (A)
Interest Rate Protection Agreements designed to protect the Company or such
Restricted Subsidiary against fluctuations in interest rates in respect of
Indebtedness of the Company or such Restricted Subsidiary that is permitted by
the terms of the Indenture to be outstanding to the extent the notional
principal amount of such obligation does not exceed the aggregate principal
amount of the Indebtedness to which such Interest Rate Protection Agreements
relate, (B) Currency Agreement Obligations in respect of foreign exchange
exposures Incurred by the Company or any Restricted Subsidiary in the ordinary
course of its business and (C) commodity agreements of the Company or such
Restricted Subsidiary to the extent entered into 


                                       42

in the ordinary course of business to protect the Company or any Restricted
Subsidiary from fluctuations in the prices of raw materials used in its
business; (viii) Indebtedness of the Company or any Restricted Subsidiary
consisting of obligations in respect of purchase price adjustments in connection
with the acquisition or disposition of assets by the Company or any Restricted
Subsidiary permitted under this Indenture; (ix) Capital Lease Obligations,
Purchase Money Indebtedness and Acquired Indebtedness (to the extent not
Incurred in connection with, or in anticipation or contemplation of, the
relevant transaction), in each case Incurred in connection with a Related
Business and any Refinancing Indebtedness in respect thereof in an aggregate
principal amount not exceeding $10.0 million at any time outstanding; (x)
Attributable Debt in connection with Sale/Leaseback Transactions in an aggregate
principal amount not exceeding $10.0 million at any time outstanding; (xi)
provided that the Company would be able to Incur $1.00 of Indebtedness pursuant

principal amount not exceeding $30.0 million at any one time outstanding; (xii)
Indebtedness in an amount not to exceed $4.5 million issued in connection with

which, together with all other Indebtedness of the Company and its Restricted
Subsidiaries then outstanding (other than Indebtedness Incurred pursuant to
clauses (i) through (xii) of this clause or clause (a) of this Section) does not
exceed $10.0 million.

            (c) Notwithstanding that such Indebtedness is permitted to be
incurred pursuant to clauses (a) and (b) of this Section 4.13, the Company shall
not, and shall not permit any Restricted Subsidiary to, Incur any Indebtedness
if the proceeds thereof are used, directly or indirectly, to repay, prepay,
redeem, defease, retire, refund or refinance any Subordinated Obligations unless
such Indebtedness shall be subordinated to the Notes or the relevant Subsidiary
Guarantee, as applicable, to at least the same extent as such Subordinated
Obligations.

            (d) For purposes of determining compliance with this Section 4.13,
in the event that an item of Indebtedness meets the criteria of more than one of
the types of Indebtedness described in clauses (a) or (b) of this Section 4.13,
the Company, in its sole discretion, at the time of the Incurrence of such
Indebtedness shall classify such item of Indebtedness, and, except as
specifically stated otherwise, only be required to include the amount of such
Indebtedness, in one of the above clauses, and such item of Indebtedness may be
divided and classified among more than one of such types.

            (e) For purposes of determining amounts of Indebtedness outstanding
under this Section 4.13 and for the purpose of avoiding duplication only,
Indebtedness resulting from security interests granted with respect to
Indebtedness otherwise included in the determination of Indebtedness, and
Guarantees (and security interests with respect thereof) of, or obligations with
respect to letters of credit supporting, Indebtedness otherwise included in the
determination of Indebtedness shall not be included in the determination of
Indebtedness.

Person becomes a Restricted Subsidiary of the Company (including upon
designation of any subsidiary or other person as a Restricted Subsidiary) or is

            The Company shall not, and shall not permit any Restricted
Subsidiary to, create, Incur, assume, Guarantee or in any other manner become
liable with respect to any Indebtedness that is subordinate in right of payment

payment to, the Notes, or the relevant Subsidiary Guarantee, as the case may be.

            SECTION 4.16. Change of Control.

            (a) Upon the occurrence of a Change of Control, each Holder shall
have the right to require that the Company repurchase all or, at each Holder's
option, any part of such Holder's Notes at a purchase price in cash equal to
101% of the principal amount thereof plus accrued and unpaid interest, if any,
to the date of purchase (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date).

            (b) Within 20 days following any Change of Control, the Company
shall mail a notice to the Trustee and to each Holder stating: (i) that a Change
of Control has occurred and that such Holder has the right to require the
Company to purchase all or a portion of such Holder's Notes at a purchase price
in cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of holders of
record on the relevant record date to receive interest on the relevant interest
payment date); (ii) the circumstances and relevant facts and financial
information regarding such Change of Control (including, to the extent
available, information with respect to pro forma historical income, cash flow

repurchase date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is mailed); and (iv) the instructions determined by
the Company, consistent with this Section 4.16, that a Holder must follow in
order to have its Notes purchased; provided, however, that notwithstanding the
occurrence of a Change of Control, the Company shall not be obligated to
repurchase the Notes pursuant to this Section 4.16 if the Company has exercised
its right to redeem all the Notes under the terms of clause 6 of the Notes.

            (c) Holders electing to have a Note purchased will be required to
surrender the Note, with an appropriate form (as provided for in Exhibit A or B,
as appropriate) duly completed, to the Company at the address specified in the

entitled to withdrawal their election if the Trustee or the Company receives not

date, a telegram, telex, facsimile transmission or letter setting forth the name
of the Holder, the principal amount of the Note which was delivered for purchase

            (d) On the purchase date, all Notes purchased by the Company under
this Section shall be delivered to the Trustee for cancellation, and the Company
shall pay or cause to be paid the purchase price plus accrued and unpaid
interest, if any, to the Holders entitled thereto.

            (e) At the time the Company delivers Notes to the Trustee which are
to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Notes are to be accepted by the Company pursuant
to and in accordance with the terms of this Section. A Note shall be deemed to
have been accepted for purchase at the time the Trustee, directly or through an
agent, mails or delivers payment therefor to the surrendering Holder.

            (f) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
Section 4.16. 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.

            (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Disposition unless (i) (x) the Company or such
Restricted Subsidiary receives consideration at the time of such Asset
Disposition at least equal to the fair market value, as determined in good faith

consideration), of the shares and assets subject to such Asset Disposition and
(y) at least 80% of the consideration thereof received by the Company or such

Cash from such Asset Disposition; (B) second, to the extent of the balance of
such Net Available Cash after application in accordance with clause (A), at the
Company's election, to the investment by the Company or any Subsidiary Guarantor
or, if the Asset Disposition


                                       45
<PAGE>

was made by a Restricted Subsidiary that is not a Subsidiary Guarantor, any
Restricted Subsidiary, in (1) assets of the Company, such Subsidiary Guarantor
or, if the Asset Disposition was made by a Restricted Subsidiary that is not a
Subsidiary Guarantor, such Restricted Subsidiary to replace the assets (other
than Indebtedness or Capital Stock) that were the subject of such Asset
Disposition or (2) assets (other than (q) inventory or other current assets or
(r) Indebtedness or Capital Stock) of the Company, any Subsidiary Guarantor or
if the Asset Disposition was made by a Restricted Subsidiary that is not a
Subsidiary Guarantor, any Restricted Subsidiary that (as determined in good
faith by the Board of Directors) are related to the business of the Company and
the Wholly Owned Subsidiaries existing on the Issue Date or which are used in a
Related Business, in each case within 360 days from the date of the Company's or
such Restricted Subsidiary's receipt of Net Available Cash from such Asset
Disposition; (C) third, to the extent of the balance of such Net Available Cash
after application in accordance with clauses (A) and (B), to make a pro rata
offer to purchase Notes at par (and, to the extent required by the instrument
governing such Indebtedness, any other Senior Subordinated Indebtedness
designated by the Company, at a price no greater than par or accreted value,
whichever is less) plus accrued and unpaid interest; and (D) fourth, to the
extent of the balance of such Net Available Cash after application in accordance
with clauses (A), (B) and (C), in any manner that does not violate this
Indenture; provided, however, that in connection with any prepayment, repayment
or purchase of Indebtedness pursuant to clause (A) or (C) above, the Company or
such Subsidiary shall permanently retire such Indebtedness and cause the related
loan commitment (if any) to be permanently reduced in an amount equal to the
principal amount so prepaid, repaid or purchased. Notwithstanding the foregoing
provisions of this clause (a), the Company and its Restricted Subsidiaries shall
not be required to apply any Net Available Cash in accordance with clause
(a)(ii)(C) of this Section 4.17 except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which are not applied in accordance
with clauses (a)(ii)(A) and (B) of this Section 4.17 exceeds $10.0 million.
Pending application of Net Available Cash pursuant to this clause (a), such Net
Available Cash shall be used to temporarily reduce Senior Indebtedness or
invested in Cash Equivalents.

            For the purposes of this Section 4.17, the following is deemed to be
cash or Cash Equivalents: the express assumption of Indebtedness (other than any
Indebtedness that is by its terms subordinated to the Notes) of the Company or
any Restricted Subsidiary, but only to the extent that such assumption is
effected on a basis under which there is no further recourse to the Company or
any of the Restricted Subsidiaries with respect to such liabilities.

            (b) In the event of an Asset Disposition that requires the purchase
of the Notes (and other Senior Subordinated Indebtedness) pursuant to clause
(a)(ii)(C) of this Section 4.17, the Company shall be required to purchase Notes
tendered pursuant to an offer by the Company for the Notes (and, to the extent
required, other Senior Subordinated Indebtedness) (the "Offer) at a purchase
price of 100% of their principal amount or the accreted value thereof, whichever
is less, (without premium) plus accrued but unpaid interest (or, in respect of
such other Senior Subordinated Indebtedness such lesser price, if any, as may be
provided for by the terms of such other Senior Subordinated Indebtedness) in
accordance with the procedures (including prorating in the event of
oversubscription) set forth in this Indenture. If the aggregate purchase price
of Notes (and, to the extent required, any other Senior 


                                       46
<PAGE>

Subordinated Indebtedness) tendered pursuant to such offer is less than the Net
Available Cash allotted to the purchase thereof, the Company shall be required
to apply the remaining Net Available Cash in accordance with clause (a)(ii)(D)
of this Section 4.17.

            (c) (1) Promptly, and in any event within 30 days after the Company
becomes obligated to make an Offer, the Company shall be obligated to deliver to
the Trustee and send, by first-class mail to each Holder, a written notice
stating that the Holder may elect to have his Notes purchased by the Company
either in whole or in part (subject to prorating as hereinafter described in the
event the Offer is oversubscribed) in integral multiples of $1,000 of principal
amount, at the applicable purchase price. The notice shall specify a purchase
date not less than 30 days nor more than 60 days after the date of such notice
(the "Purchase Date") and shall contain such information which the Company in
good faith believes will enable such Holders to make an informed decision.

            (2) Not later than the date upon which written notice of an Offer is
      delivered to the Trustee as provided above, the Company shall deliver to
      the Trustee an Officers' Certificate as to (i) the amount of the Offer
      (the "Offer Amount'), (ii) the allocation of the Net Available Cash from
      the Asset Dispositions pursuant to which such Offer is being made and
      (iii) the compliance of such allocation with the provisions of Section
      4.17(a). Upon the expiration of the period for which the Offer remains
      open (the "Offer Period"), the Company shall deliver to the Trustee for
      cancellation the Notes or portions thereof which have been properly
      tendered to and are to be accepted by the Company. The Trustee shall, on
      the Purchase Date, mail or deliver payment to each tendering Holder in the
      amount of the purchase price. In the event that the aggregate purchase
      price of the Notes delivered by the Company to the Trustee is less than
      the Offer Amount, the Trustee shall deliver the excess to the Company
      immediately after the expiration of the Offer Period for application in
      accordance with this Section.

            (3) Holders electing to have a Note purchased shall be required to
      surrender the Note, with an appropriate form duly completed, to the
      Company at the address specified in the notice not later than 3:00 p.m.,
      New York City time, two Business Days prior to the Purchase Date. Holders
      shall be entitled to withdraw their election if the Trustee or the Company
      receives not later than 3:00 p.m., New York City time, two Business Days
      prior to the Purchase Date, a telegram, telex, facsimile transmission or
      letter setting forth the name of the Holder, the principal amount of the
      Note which was delivered for purchase by the Holder and a statement that
      such Holder is withdrawing his election to have such Note purchased. If at
      the expiration of the Offer Period the aggregate principal amount of Notes
      surrendered by Holders exceeds the Offer Amount, the Company shall select
      the Notes to be purchased on a pro rata basis taking into account any
      other tendered Senior Subordinated Indebtedness which is the subject of
      such offer (with such adjustments as may be deemed appropriate by the
      Company so that only Notes in denominations of $ 1,000, or integral
      multiples thereof, shall be purchased). Holders whose Notes are purchased
      only in part shall be issued new Notes equal in principal amount to the
      unpurchased portion of the Notes surrendered.


                                       47
<PAGE>

            (4) At the time the Company delivers Notes to the Trustee which are
      to be accepted for purchase, the Company shall also deliver an Officers'
      Certificate stating that such Notes are to be accepted by the Company
      pursuant to and in accordance with the terms of this Section. A Note shall
      be deemed to have been accepted for purchase at the time the Trustee,
      directly or through an agent, mails or delivers payment therefor to the
      surrendering Holder.

            (d) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
Section 4.17. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.17, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.17 by virtue
thereof.

            SECTION 4.18. Limitation on Liens Securing Subordinated
                          Indebtedness.

            The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, Incur, assume or suffer to exist
any Liens of any kind (other than Permitted Liens) upon any of their respective
assets or properties now owned or acquired after the date of this Indenture or
any income or profits therefrom securing (i) any Indebtedness of the Company or
a Restricted Subsidiary which is expressly by its terms subordinate or junior in
right of payment to any other Indebtedness of the Company or such Restricted
Subsidiary, as the case may be, unless the Notes or the relevant Subsidiary
Guarantee, as the case may be, are equally and ratably secured for so long as
such Indebtedness is so secured; provided that, if such Indebtedness which is
expressly by its terms subordinate or junior in right of payment to any other
Indebtedness of the Company or a Restricted Subsidiary is expressly subordinate
or junior to the Notes or the relevant Subsidiary Guarantee, as the case may be,
then the Lien securing such subordinated or junior Indebtedness shall be
subordinate and junior to the Lien securing the Notes or the relevant Subsidiary
Guarantee, as the case may be, with the same relative priority as such
subordinated or junior Indebtedness shall have with respect to the Notes or the
relevant Subsidiary Guarantee, as the case may be or (ii) any assumption,
Guarantee or other liability of the Company or such Restricted Subsidiary in
respect of any Indebtedness of the Company or a Restricted Subsidiary which is
expressly by its terms subordinate or junior in right of payment to any other
Indebtedness of the Company or such Restricted Subsidiary, unless the Notes or
the relevant Subsidiary Guarantee, as the case may be, are equally and ratably
secured for so long as such assumption, guaranty or other liability is so
secured; provided that, if such subordinated Indebtedness which is expressly by
its terms subordinate or junior in right of payment to any other Indebtedness of
the Company or a Restricted Subsidiary is expressly by its terms subordinate or
junior to the Notes or the relevant Subsidiary Guarantee, as the case may be,
then the Lien securing the assumption, Guarantee or other liability of such
Subsidiary shall be subordinate and junior to the Lien securing the Notes or the
relevant Subsidiary Guarantee, as the case may be, with the same relative
priority as such subordinated or junior Indebtedness shall have with respect to
the Notes or the relevant Subsidiary Guarantee, as the case may be.

            SECTION 4.19. Future Subsidiary Guarantors.


                                       48
<PAGE>

            The Company shall cause each Restricted Subsidiary of the Company,
and each Subsidiary Guarantor shall cause each Restricted Subsidiary which is a
subsidiary of such Subsidiary Guarantor, (other than SPCs) (a) that is organized
or existing under the laws of the United States, any state thereof or the
District of Columbia, (b) more than 65% of the Capital Stock of which is pledged
to a United States lender or (c) that Guarantees any Indebtedness owed to a
United States lender, on and after the date of this Indenture (if not then a
Subsidiary Guarantor), that becomes a Restricted Subsidiary to execute and
deliver an indenture supplemental to this Indenture and thereby become a
Subsidiary Guarantor which shall be bound by the Subsidiary Guarantee of the
Notes in the form set forth in this Indenture (without such future Subsidiary
Guarantor being required to execute and deliver the Subsidiary Guarantee
endorsed on the Notes). The Company shall not permit any Restricted Subsidiary
that is not a Subsidiary Guarantor to (i) Guarantee any other Indebtedness of
the Company or any Subsidiary Guarantor or (ii) otherwise become obligated with
respect to Indebtedness of the Company or any Subsidiary Guarantor, including
but not limited to, Indebtedness Incurred by the Company or a Subsidiary
Guarantor under the Credit Facility, unless such Restricted Subsidiary
simultaneously executes a supplemental indenture to this Indenture providing for
the Guarantee of the payment of the Notes by such Restricted Subsidiary, which
Guarantee of the payment of the Notes shall be subordinated to the Guarantee of
such other Indebtedness to the same extent as the Notes or the Subsidiary
Guarantees, as applicable, are subordinated to such other Indebtedness;
provided, however, that such Restricted Subsidiary shall not be required to so
Guarantee the payment of the Notes to the extent that such other Indebtedness
does not exceed $1 million individually or, together with any other Indebtedness
of the Company or any Subsidiary Guarantor Guaranteed by such Restricted
Subsidiary, $3 million in the aggregate. Such Restricted Subsidiary shall be
deemed released from its obligations under the Guarantee of the payment of the
Notes at any such time that such Restricted Subsidiary is released from all of
its obligations under its Guarantee of such other Indebtedness unless such
release results from the payment under such Guarantee of other Indebtedness.

            SECTION 4.20. Limitation on Designations of Unrestricted
                          Subsidiaries.

            (a) The Company may designate any Subsidiary of the Company (other
than a Subsidiary Guarantor) as an "Unrestricted Subsidiary"(a "Designation")
only if:

            (i) no Default shall have occurred and be continuing at the time of
      or after giving effect to such Designation; and

            (ii) either (x) the assets of such Subsidiary do not exceed $1,000
      or (y) the Company would be permitted under this Indenture to make an
      Investment at the time of Designation (assuming the effectiveness of such
      Designation) in an amount (the "Designation Amount") equal to the fair
      market value of the Company's Investment in such Subsidiary on such date.

            In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
4.10 for all purposes of this Indenture in the Designation Amount. The Company
shall not, and shall not permit 


                                       49
<PAGE>

any Restricted Subsidiary to, at any time (a) provide credit support for, or a
Guarantee of, any Indebtedness of any Unrestricted Subsidiary (including any
undertaking, agreement or instrument evidencing such Indebtedness) or (b) be
directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary.

            (b) The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

            (i) no Default shall have occurred and be continuing at the time of
      and after giving effect to such Revocation; and

            (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
      outstanding immediately following such Revocation would, if Incurred at
      such time, have been permitted to be Incurred for all purposes of this
      Indenture and for all purposes of this Indenture shall be deemed to have
      been Incurred at such time.

            All Designations and Revocations must be evidenced by resolutions of
the Board of Directors delivered to the Trustee certifying compliance with the
foregoing provisions.

            Notwithstanding the foregoing, no Subsidiary that is a Subsidiary
Guarantor as of the Issue Date shall be permitted to become an Unrestricted
Subsidiary.

            SECTION 4.21. Limitation on Lines of Business.

            Neither the Company nor any of its Subsidiaries shall directly or
indirectly engage to any substantial extent in any line or lines of business
activity other than that which, in the reasonable good faith judgment of the
Board of Directors, is a Related Business.

            SECTION 4.22. Limitation on Holdco and the Holding Companies.

            Holdco and the Holding Companies shall not, and the Company shall
not permit the Holding Companies to, engage in any business other than holding
the securities of their respective direct subsidiaries.

            SECTION 5.01. Merger, Consolidation and Sale of Assets of the

            The Company shall not, in a single transaction or a series of
related transactions, consolidate with or merge with or into, or sell, assign,
convey, transfer, lease or otherwise dispose of all or substantially all its
assets (computed on a consolidated basis) to, any Person or group of affiliated
Persons, unless: (i) the resulting, surviving or transferee Person 


                                       50
<PAGE>

shall be the Company or, if not the Company, shall be a corporation organized
and existing under the laws of the United States of America, any State thereof
or the District of Columbia (the "Successor Company"), and such Successor
Company shall expressly assume, by an indenture supplemental to this Indenture
in a form reasonably satisfactory to the Trustee, executed and delivered to the
Trustee, all the obligations of the Company under the Notes and this Indenture
(and the Guarantees shall be confirmed as applying to such Person's
obligations); (ii) at the time of and immediately after giving effect to such
transaction or transactions on a pro forma basis (and treating any Indebtedness
which becomes an obligation of the resulting, surviving or transferee Person or
any Subsidiary as a result of such transaction as having been Incurred by such
Person or such Subsidiary at the time of such transaction), no Default or Event
of Default shall have occurred and be continuing; (iii) immediately after giving
effect to such transaction (and treating any Indebtedness which becomes an
obligation of the resulting, surviving or transferee Person or any Subsidiary as
a result of such transaction as having been Incurred by such Person or such
Subsidiary at the time of such transaction) the resulting, surviving or
transferee Person would be able to Incur at least $1.00 of Indebtedness pursuant
to clause (a) of Section 4.13; and (iv) the Company shall have delivered to the
Trustee an Officers' Certificate and if a supplemental indenture is required, an
Opinion of Counsel, each stating that such consolidation, merger or transfer and
such supplemental indenture (if any) comply with this Indenture.

            Notwithstanding the foregoing, (i) the consolidation or merger of
the Company with, or (ii) the sale, assignment, conveyance, transfer, lease or
other disposition by the Company of all or substantially all of its property or
assets to, one or more Subsidiaries of the Company shall not relieve the Company
from its obligations under the Notes and this Indenture.

            For purposes of the foregoing, the transfer (by sale, assignment,
conveyance, transfer, lease or otherwise) of all or substantially all of the
properties and assets of one or more Subsidiaries, the Company's interest in
which constitutes all or substantially all of the properties and assets of the
Company shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

            SECTION 5.02. Successor Corporation Substituted for the Company.

            Upon any consolidation, combination or merger or any transfer of all
or substantially all of the assets of the Company in accordance with the
foregoing, in which the Company is not the continuing corporation, the Successor
Company formed by such consolidation or into which the Company is merged or to
which such sale, assignment, conveyance, transfer or lease is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture and the Notes with the same effect as if such
surviving entity had been named as such, and the predecessor company, in the
case of a sale, assignment, conveyance, transfer or other disposition (but not
in the case of a lease), shall be released from the obligation to pay the
principal of and interest on the Notes.

            SECTION 5.03. Merger, Consolidation and Sale of Assets of Any

<PAGE>

                          Subsidiary Guarantor.

            The Company shall not permit any Subsidiary Guarantor to consolidate
with or merge with or into, or sell, assign, convey, transfer, lease or
otherwise dispose of, in one transaction or a series of transactions, all or
substantially all of its assets to, any Person unless: (i) the resulting,
surviving or transferee Person shall be the Company or a Subsidiary Guarantor
or, if not the Company or such a Subsidiary Guarantor, shall be a corporation
organized and existing under the laws of the jurisdiction under which such
Subsidiary was organized or under the laws of the United States of America, or
any State thereof or the District of Columbia, and such Person shall expressly
assume, by executing a Subsidiary Guarantee, all the obligations of such
Subsidiary, if any, under its Subsidiary Guarantee; (ii) immediately after
giving effect to such transaction or transactions on a pro forma basis (and
treating any Indebtedness which becomes an obligation of the resulting,
surviving or transferee Person as a result of such transaction as having been
issued by such Person at the time of such transaction), no Default or Event of
Default shall have occurred and be continuing; (iii) immediately after giving
effect to such transaction, the Company would be able to Incur at least $1.00 of
Indebtedness pursuant to Section 4.13(a); and (iv) the Company delivers to the
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger or transfer and such Subsidiary Guarantee, if any,
complies with this Indenture. The provisions of clauses (i), (ii) and (iii)
above shall not apply to any one or more transactions which constitute an (a)
Asset Disposition subject to the applicable provisions of the covenant described
under Section 4.17 or (b) the grant of any Lien on the assets of a Restricted
Subsidiary to secure outstanding Indebtedness under the Credit Facility, which
Lien is permitted by the terms of this Indenture, or any conveyance or transfer
of such assets resulting from an exercise of remedies in respect of any such
Lien.

            Notwithstanding the foregoing, but subject to the terms of the first
paragraph of Section 5.01 and this Section 5.03, the Company may merge with or
into, or sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all of its assets to, any Subsidiary Guarantor, and a Subsidiary
Guarantor may merge with or into, or sell, assign, convey, transfer or lease all
or substantially all of its assets to, any other Subsidiary Guarantor.

            SECTION 5.04. Successor Corporation Substituted for Subsidiary
                          Guarantor.

            Upon any consolidation, combination or merger or any transfer of all
or substantially all of the assets of any Subsidiary Guarantor in accordance
with the foregoing, in which such Subsidiary Guarantor is not the continuing
corporation, the successor Person formed by such consolidation or into which
such Subsidiary Guarantor is merged or to which such conveyance, lease or
transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, such Subsidiary Guarantor under this Indenture with
the same effect as if such surviving entity had been named as such, and the
predecessor company, in the case of a conveyance, transfer or lease, shall be
released from the obligation to pay the principal of and interest on the Notes.

      stayed (including pending appeal); or

            (10) any Subsidiary Guarantee of a Significant Subsidiary ceases to
      be in full force and effect or becomes unenforceable or invalid or is
      declared null and void (other than in accordance with the terms of the
      Subsidiary Guarantee or this Indenture) or any Subsidiary Guarantor that
      is a Significant Subsidiary denies or disaffirms its obligations under its
      Subsidiary Guarantee.

            However, a default under clause (4) or (5) shall not constitute an
Event of Default until the Trustee or the Holders of 25% in principal amount of
the outstanding Notes notify the Company of the default and the Company does not
cure such default within the time specified after receipt of such notice.

            The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6) or (10) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4), (5) or (9), its status and what action the Company is taking or
proposes to take with respect thereto.

            SECTION 6.02. Acceleration.

            (a) If an Event of Default (other than an Event of Default specified
in Section 6.01(7) or (8) with respect to the Company) occurs and is continuing,
and has not been waived pursuant to Section 6.04, then the Trustee, by written
notice to the Company, or the Holders of at least 25% in principal amount of
outstanding Notes may declare the principal of and accrued but unpaid interest
on all the Notes to be due and payable by notice in writing to the Company and
the Trustee specifying the respective Event of Default and that it is a "notice
of acceleration". Upon any such declaration, such amount shall be immediately
due and payable provided, however, that for so long as the Credit Facility
remains in effect, such declaration shall not become effective until the earlier
of (i) five Business Days following delivery of notice to the Representative of
such creditors of the intention to accelerate the Notes or (ii) the acceleration
of any Indebtedness under the Credit Facility.


                                       54
<PAGE>

            (b) If an Event of Default specified in Section 6.01(7) or (8)
relating to the Company or any Significant Subsidiary occurs and is continuing,
the principal of and interest on all the Notes shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders.

            (c) The Holders of a majority in principal amount of the Notes may,
on behalf of the Holders of all of the Notes, rescind and cancel an acceleration
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) if the Company has paid the Trustee its reasonable
compensation and reimbursed the Trustee for its expenses, disbursements and
advances and (iv) in the event of the cure or waiver of an Event of Default of
the type described in Section 6.01(7) or 6.01(8), 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 Notes or to enforce the performance
of any provision of the Notes or this Indenture.

            The Trustee may maintain a proceeding even if it does not possess
any of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder 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 a majority
in principal amount of the then outstanding Notes by notice to the Trustee may,
on behalf of the Holders of all of the Notes, waive an existing Default or Event
of Default and its consequences, except a Default in the payment of principal of
or interest on any Note as specified in clauses (1) and (2) of Section 6.01.
When a Default or Event of Default is waived, it is cured and ceases.

            SECTION 6.05. Control by Majority.

            Subject to Section 2.09, the Holders of a majority in principal
amount of the then outstanding Notes 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, including, without limitation, any remedies
provided for in Section 6.03. Subject to 


                                       55
<PAGE>

Section 7.01, however, the Trustee may refuse to follow any direction that the
Trustee reasonably believes conflicts with any law or this Indenture, that the
Trustee reasonably determines may be unduly prejudicial to the rights of another
Holder, 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; and provided further, that this provision
shall not affect the rights of the Trustee set forth in Sections 6.06, 7.01(d)
and 7.02(f).

            SECTION 6.06. Limitation on Suits.

            Subject to Article Seven, if an Event of Default occurs and is
continuing, the Trustee shall be under no obligation to exercise any of the
rights or powers under this Indenture at the request or direction of any of the
Holders unless such Holders have offered to the Trustee indemnity or security
against any loss, liability or expense reasonably satisfactory to the Trustee.
Except to enforce the right to receive payment of principal, premium (if any) or
interest when due, no Holder of a Note may pursue any remedy with respect to
this Indenture or the Notes unless (i) such Holder has previously given the
Trustee notice that an Event of Default is continuing, (ii) Holders of at least
25% in principal amount of the outstanding Notes have requested the Trustee to
pursue the remedy, (iii) such Holders have offered the Trustee security or
indemnity against any loss, liability or expense reasonably satisfactory to the
Trustee, (iv) the Trustee has not complied with such request within 60 days
after the receipt thereof and the offer of security or indemnity and (v) the
Holders of a majority in principal amount of the outstanding Notes have not
given the Trustee a direction inconsistent with such request within such 60-day
period.

            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 Note, on or
after the respective due dates expressed in such Note, 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 such Holder.

            SECTION 6.08. Collection Suit by Trustee.

            If an Event of Default in payment of principal or interest specified
in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any other obligor on the Notes for the whole amount of principal and
accrued interest remaining unpaid, together with interest on overdue principal
and, to the extent that payment of such interest is lawful, interest on overdue
installments of interest at the rate set forth on the face of the Note and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents, consultants and counsel.

            SECTION 6.09. Trustee May File Proofs of Claim.


                                       56
 
<PAGE>

            The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, taxes,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relating to the Company or any other
obligor upon the Notes, any of their respective creditors or any of their
respective property and shall be entitled and empowered to collect and receive
any monies or other property payable or deliverable on any such claims and to
distribute the same, and any Custodian in any such judicial proceedings is
hereby authorized by each Holder to make such payments to the Trustee and, if
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, taxes, disbursements and advances of the Trustee, its
agents, consultants and counsel, and any other amounts due the Trustee under
Section 7.07. The Company's payment obligations under this Section 6.09 shall be
secured in accordance with the provisions of Section 7.07 hereunder. Nothing
herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

            SECTION 6.10. Priorities.

            If the Trustee collects any money or property pursuant to this
Article Six, it shall pay out the money in the following order:

            First: to the Trustee for amounts due under Section 7.07;

            Second: if the Holders are forced to proceed against the Company
      directly without the Trustee, to Holders for their collection costs;

            Third: to Holders for amounts due and unpaid on the Notes for
      principal and interest, ratably, without preference or priority of any
      kind, according to the amounts due and payable on the Notes for principal
      and interest, respectively; and

            Fourth: to the Company or any other obligor on the Notes, as their
      interests may appear, or as a court of competent jurisdiction may direct.

            The Trustee, upon prior notice to the Company, may fix a record date
and payment date for any payment to Holders pursuant to this Section 6.10.

            SECTION 6.11. Undertaking for Costs.

            In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits 


                                       57
<PAGE>

and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in
principal amount of the outstanding Notes.

                                  ARTICLE SEVEN

                                     TRUSTEE

            SECTION 7.01. Duties of Trustee.

            (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in its exercise thereof as a
prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

            (b) Except during the continuance of an Event of Default:

            (1) The Trustee need perform only those duties as are specifically
      set forth in this Indenture and no covenants or obligations shall be
      implied in this Indenture against the Trustee.

            (2) In the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee shall examine the certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture.

            (c) Notwithstanding anything to the contrary herein contained, the
Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act, or its own wilful misconduct, except that:

            (1) This paragraph does not limit the effect of paragraph (b) of
      this Section 7.01.

            (2) The Trustee shall not be liable for any error of judgment made
      in good faith by a Trust Officer, unless it is proved that the Trustee was
      negligent in ascertaining the pertinent facts.

            (3) The Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.02, 6.04 or 6.05.

            (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties 


                                       58
<PAGE>

hereunder or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not assured to it.

            (e) Whether or not herein expressly provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), (c) and (d) of this Section 7.01.

            (f) The Trustee shall not be liable for interest on any money or
assets received by it except as the Trustee may agree in writing with the
Company. Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

            SECTION 7.02. Rights of Trustee.

            Subject to Section 7.01:

            (a) The Trustee may rely and shall be fully protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, note or other
paper or document reasonably believed by it to be genuine and to have been
signed or presented by the proper Person. The Trustee need not investigate any
fact or matter stated in the document.

            (b) Before the Trustee acts or refrains from acting, it may consult
with counsel and may require an Officers' Certificate, an Opinion of Counsel or
both, which shall conform to Sections 13.04 and 13.05. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel.

            (c) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or indirectly or by or through
agents or attorneys and the Trustee shall not be responsible for the misconduct
or negligence of any agent or attorney appointed with due care.

            (d) The Trustee shall not be liable for any action that it takes or
omits to take in good faith which it reasonably believes to be authorized or
within its rights or powers; provided, however that the Trustee's conduct does
not constitute wilful misconduct, negligence or bad faith.

            (e) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, notice, request, direction, consent, order, bond,
debenture, or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled, upon reasonable notice to the Company, to
examine the books, records, and premises of the Company, personally or by agent
or attorney and to consult with the officers and representatives of the Company,
including the Company's accountants and attorneys.


                                       59
<PAGE>

            (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee security or indemnity
satisfactory to the Trustee against the loss, expenses and liabilities which may
be incurred by it in compliance with such request, order or direction.

            (g) The Trustee shall not be required to give any bond or surety in
respect of the performance of its powers and duties hereunder.

            (h) The Trustee may determine (i) the execution by any Holder of any
instrument in writing, (ii) the date of such execution or (iii) the authority of
any Person executing the same, in any manner the Trustee deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

            (i) The Trustee may consult with counsel, and the advice or opinion
of counsel with respect to legal matters relating to this Indenture and the
Notes shall be full and complete authorization and protection from liability in
respect to any action taken, omitted or suffered by it hereunder in good faith
and in accordance with the advice or opinion of such counsel.

            SECTION 7.03. Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company, any
Subsidiary of the Company, or their respective Affiliates with the same rights
it would have if it were not Trustee. However, if the Trustee acquires any
conflicting interest within the meaning of Section 3.10(b) of the TIA, it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. Any Agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

            SECTION 7.04. Trustee's Disclaimer.

            The Offering Circular and the recitals contained herein and in the
Notes shall be taken as statements of the Company and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representation as to
the validity or adequacy of this Indenture or the Notes, and it shall not be
accountable for the Company's use of the proceeds from the Notes, and it shall
not be responsible for any statement of the Company in this Indenture or the
Notes other than the Trustee's certificate of authentication.

            SECTION 7.05. Notice of Default.

            If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Holder notice of the Default within 90
days after such Default occurs. Except in the case of a Default in payment of
principal of, or interest on, any Note, including an accelerated payment and the
failure to make payment on the purchase date 


                                       60
<PAGE>

pursuant to a Change in Control under Section 4.16 and, except in the case of a
failure to comply with Article Five hereof, the Trustee may withhold the notice
if and so long as its board of directors, the executive committee of its board
of directors or a committee of its Trust Officers in good faith reasonably
determines that withholding the notice is in the best interest of the Holders.
In addition, the Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year, a certificate regarding knowledge of the Company's
compliance with all covenants and conditions under this Indenture. The Company
also shall deliver to the Trustee pursuant to Section 6.01, within 30 days after
the occurrence thereof, written notice of any event which would constitute
certain Defaults, their status and what action the Company is taking or proposes
to take in respect thereof.

            SECTION 7.06. Reports by Trustee to Holders.

            Within 60 days after each May 15, beginning with the May 15 
following the date of this Indenture, the Trustee shall, to the extent that 
any of the events described in TIA Section  313(a) occurred within the 
previous twelve months, but not otherwise, mail to each Holder a brief report 
dated as of such date that complies with TIA Section  313(a). The Trustee 
also shall comply with TIA Section Section  313(b) and (c).

            The Company shall promptly notify the Trustee if the Notes become 
listed on, or delisted from, any stock exchange and the Trustee shall comply 
with TIA Section  313(d).

            SECTION 7.07. Compensation and Indemnity.

            The Company shall pay to the Trustee from time to time reasonable 
compensation for its services. The Trustee's compensation shall not be 
limited by any law on compensation of a trustee of an express trust. The 
Company shall reimburse the Trustee upon request for all reasonable fees and 
expenses, including out-of-pocket expenses incurred or made by it in 
connection with the performance of its duties under this Indenture. Such 
expenses shall include the reasonable fees and expenses of the Trustee's 
agents, consultants, experts and counsel.

            The Company shall indemnify the Trustee and its agents, 
employees, stockholders and directors and officers for, and hold them 
harmless against, any loss, liability or expense incurred by them, arising 
out of or in connection with the administration of this trust including the 
reasonable costs and expenses of defending themselves against any claim or 
liability in connection with the exercise or performance of any of their 
rights, powers or duties hereunder. The Company need not reimburse any 
expense or indemnify against any loss, liability or expense Incurred by the 
Trustee through the Trustee's own wilful misconduct, negligence or bad faith. 
The Trustee shall notify the Company promptly of any claim asserted against 
the Trustee for which it may seek indemnity. At the Trustee's sole 
discretion, the Company shall defend the claim and the Trustee shall 
cooperate and may participate in the defense; provided that any settlement of 
a claim shall be approved in writing by the Trustee. Alternatively, the 
Trustee may at its option have separate counsel of its own choosing and the 
Company shall pay the reasonable fees and expenses of such counsel; provided 
that the Company shall not be required to pay such fees and expenses if it 
assumes the Trustee's

                                       61
<PAGE>

defense and there is no conflict of interest between the Company and the 
Trustee in connection with such defense as reasonably determined by the 
Trustee. The Company need not pay for any settlement made without its written 
consent. The Company need not reimburse any expense or indemnify against any 
loss or liability to the extent incurred by the Trustee through its 
negligence, bad faith or wilful misconduct.

            To secure the Company's payment obligations in this Section 7.07, 
the Trustee shall have a lien prior to the Notes on all assets or money held 
or collected by the Trustee, in its capacity as Trustee, except assets or 
money held in trust to pay principal of or interest on particular Notes. The 
Trustee's right to receive payment of any amounts due under this Section 7.07 
shall not be subordinate to any other liability or indebtedness of the 
Company (even though the Notes may be subordinate to such other liability or 
indebtedness).

            When the Trustee incurs expenses or renders services after an 
Event of Default specified in Section 6.01(7) or (8) occurs, such expenses 
and the compensation for such services are intended to constitute expenses of 
administration under any Bankruptcy Law; provided, however, that this shall 
not affect the Trustee's rights as set forth in the preceding paragraph or 
Section 6.10.

            SECTION 7.08. Replacement of Trustee.

            The Trustee may resign at any time by so notifying the Company in 
writing at least 30 days prior to the date of the proposed resignation. The 
Holders of a majority in principal amount of the outstanding Notes may remove 
the Trustee by so notifying the Company and the Trustee and may appoint a 
successor Trustee. The Company may remove the Trustee if:

            (A) the Trustee fails to comply with Section 7.10;

            (B) the Trustee is adjudged bankrupt or insolvent or an order for
      relief is entered with respect to the Trustee under any Bankruptcy Law;

            (C) a receiver or other public officer takes charge of the Trustee
      or its property; or

            (D) the Trustee becomes incapable of acting.

            A resignation or removal of the Trustee and appointment of a 
successor Trustee shall become effective only upon the successor Trustee's 
acceptance of appointment as provided in this Section.

            If the Trustee resigns or is removed as Trustee or if a vacancy
exists in the office of Trustee for any reason, the Company shall notify each
Holder of such event and shall promptly appoint a successor Trustee. Within one
year after the successor Trustee takes office, the Holders of a majority in
principal amount of the Notes may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.


                                       62
<PAGE>

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Holder.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the then outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

            If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

            Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

            SECTION 7.09. Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee; provided that such
corporation shall be otherwise qualified and eligible under this Article Seven.

            If at the time such successor or successors by merger, conversion,
consolidation or transfer of assets to the Trustee shall succeed to the trust
created by this Indenture any of the Notes shall have been authenticated but not
delivered, any successor to the Trustee may adopt a certificate of
authentication of any predecessor Trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Trustee may authenticate such Notes either
in the name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Notes or in this Indenture provided that the certificate
of the Trustee shall have.

            SECTION 7.10. Eligibility; Disqualification.

            This Indenture shall always have a Trustee who satisfies the 
requirements of TIA Sections 310(a)(1), (2) and (5). The Trustee (or, in the 
case of a corporation included in a bank holding company system, the related 
bank holding company) shall have a combined capital and surplus of at least 
$50 million as set forth in its most recent published annual report of

system, the Trustee, independently of such bank holding company, shall meet 
the capital requirements of TIA Section  310(a)(2). The Trustee shall comply 
with TIA Section 310(b); provided, however, that there shall be excluded from 
the operation of TIA Section  310(b)(1) any indenture or indentures under 
which other securities, or certificates of interest or participation in other 
securities, of the Company are outstanding, if the requirements for such 
exclusion set forth in TIA Section 310(b)(1) are met. The provisions of TIA 
Section  310 shall apply to the Company, as obligor of the Notes.

            SECTION 7.11. Preferential Collection of Claims Against Company.

            The Trustee shall comply with TIA Section  311(a), excluding any 
creditor relationship listed in TIA Section  311(b). A Trustee who has 
resigned or been removed shall be subject to TIA Section  311(a) to the 
extent indicated therein.

                       DISCHARGE OF INDENTURE; DEFEASANCE

            SECTION 8.01. Discharge of Liability on Notes; Defeasance.

            (a) When (i) the Company delivers to the Trustee all outstanding
Notes (other than Notes replaced pursuant to Section 2.07) for cancellation or
(ii) all outstanding Notes have become due and payable at maturity or shall be
due and payable within 60 days as a result of the mailing of a notice of
redemption pursuant to Article Three hereof, in each case, and the Company
irrevocably deposits with the Trustee funds sufficient to pay at maturity or
upon redemption all outstanding Notes, including interest thereon to maturity or
such redemption date (other than Notes replaced pursuant to Section 2.07), and
if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 8.01(c), cease to be of
further effect. The Trustee shall acknowledge satisfaction and discharge of this
Indenture on demand of the Company accompanied by an Officers' Certificate and
an Opinion of Counsel as to the satisfaction of all conditions to such
satisfaction and discharge of this Indenture and at the cost and expense of the
Company.

            (b) Subject to Sections 8.01(c) and 8.02, the Company at any time
may terminate (i) all its obligations under the Notes and this Indenture ("legal
defeasance option") or (ii) its obligations under Sections 4.8 and 4.10 through
4.23 and the operation of Section 6.01(4) and the limitations contained in
clause (iii) of the first paragraph of each Section 5.01 and Section 5.03
("covenant defeasance option"). The Company may exercise its legal defeasance
option notwithstanding its prior exercise of its covenant defeasance option.

            If the Company exercises its legal defeasance option, payment of the
Notes may not be accelerated because of an Event of Default. If the Company
exercises its covenant defeasance option, payment of the Notes may not be
accelerated because of an Event of Default specified in Section 6.01(4) or
because of the failure of the Company to comply with clause (iii) of the first
paragraph of each Section 5.01 and Section 5.03. If the Company


                                       64
<PAGE>

exercises its legal defeasance option or its covenant defeasance option, each
Subsidiary Guarantor, if any, shall be released from all its obligations under
its Subsidiary Guarantee.

            Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

            (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.07, 2.08, 7.07, 7.08, 8.05, 8.06 and
the Appendix shall survive until the Notes have been paid in full. Thereafter,
the Company's obligations in Sections 7.07, 8.05 and 8.06 shall survive.

            SECTION 8.02. Conditions to Defeasance.

            The Company may exercise its legal defeasance option or its covenant
defeasance option only if:

            (1) the Company irrevocably deposits in trust with the Trustee money
      or U.S. Government Obligations for the payment of principal of, interest
      and premium, if any, on the Notes to maturity or redemption (including, in
      the case of payment of principal, interest and premium, if any, to
      redemption, under arrangements reasonably satisfactory to the Trustee
      providing for redemption pursuant to irrevocable instructions delivered to
      the Trustee prior to 60 days before a Redemption Date), as the case may
      be;

            (2) the Company delivers to the Trustee a certificate from a
      nationally recognized firm of independent public accountants or a
      nationally recognized investment banking firm expressing their opinion
      that the payments of principal and interest when due and without
      reinvestment on the deposited U.S. Government Obligations plus any
      deposited money without investment shall provide cash at such times and in
      such amounts as shall be sufficient to pay principal, premium, if any, and
      interest when due on all outstanding Notes to maturity or redemption, as
      the case may be;

            (3) (x) no Default or Event of Default with respect to the Notes
      shall have occurred and be continuing on the date of such deposit and (y)
      no Event of Default under Section 6.01(7) or (8) shall occur at any time
      in the period ending on the 123rd day after the date of such deposit (it
      being understood that the condition set forth in the preceding clause (y)
      is a condition subsequent which shall not be deemed satisfied until the
      expiration of such 123-day period, but in the case of the covenant
      defeasance, the covenants which are defeased under Section 8.01(b) shall
      cease to be in effect unless an Event of Default under Section 6.01(7) or
      (8) occurs during such period);

            (4) the Company delivers 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, 


                                       65
<PAGE>

      delaying or defrauding any other creditors of the Company and the deposit
      is not prohibited under any Designated Senior Indebtedness;

            (5) neither the deposit nor the defeasance shall result in a default
      or event of default under any other material agreement to which the
      Company is a party or by which the Company is bound and neither the
      deposit nor the defeasance shall be prohibited by Article Ten;

            (6) the Company delivers to the Trustee an Opinion of Counsel to the
      effect that the trust resulting from the deposit does not constitute, or
      is qualified as, a regulated investment company under the Investment
      Company Act of 1940;

            (7) in the case of the legal defeasance option, the Company shall
      have delivered to the Trustee an Opinion of Counsel stating that (i) the
      Company has received from, or there has been published by, the Internal
      Revenue Service a ruling, or (ii) 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 Noteholders shall not recognize income, gain or loss for
      Federal income tax purposes as a result of such defeasance and shall 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 defeasance had not
      occurred;

            (8) in the case of the covenant defeasance option, the Company shall
      have delivered to the Trustee an Opinion of Counsel to the effect that the
      Noteholders shall not recognize income, gain or loss for Federal income
      tax purposes as a result of such covenant defeasance and shall 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; and

            (9) the Company delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that all conditions precedent to the
      defeasance and discharge of the Notes as contemplated by this Article
      Eight have been complied with.

            Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Notes at a future date in
accordance with Article Three.

            SECTION 8.03. Application of Trust Money.

            The Trustee shall hold in trust money or U.S. Government Obligations
deposited with it pursuant to this Article Eight. It shall apply the deposited
money and the money from U.S. Government Obligations through the Paying Agent
and in accordance with this Indenture to the payment of principal of and
interest on the Notes. Money and securities so held in trust are not subject to
Article Ten.

            SECTION 8.04. Repayment to Company.


                                       66
<PAGE>

            The Trustee and the Paying Agent shall promptly turn over to the
Company, upon delivery of an Officers' Certificate stating that such payment
does not violate the terms of this Indenture, any excess money or securities
held by them at any time, subject to Section 7.07.

            Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Company upon its written request any money
held by them for the payment of principal or interest that remains unclaimed for
two years, and, thereafter, Noteholders entitled to the money must look to the
Company for payment as general creditors.

            SECTION 8.05. Indemnity for Government Obligations.

            The Company shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S.
Government Obligations.

            SECTION 8.06. Reinstatement.

            If the funds deposited with the Trustee to effect legal defeasance
or covenant defeasance are insufficient to pay the principal of, premium, if
any, and interest on the Notes when due, then the obligations of the Company and
the Subsidiary Guarantors under the Indenture shall be revived and no such
defeasance shall be deemed to have occurred.

            If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or U.S. Government Obligations in accordance 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 and the Subsidiary Guarantors' obligations under
this Indenture and the Notes 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 8; provided, however,
that, if the Company has made any payment of interest on or principal of any
Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the U.S. Legal Tender or U.S. Government Obligations held by the Trustee or
Paying Agent.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

            SECTION 9.01. Without Consent of Holders.

            The Company, when authorized by a Board Resolution, and the Trustee,
together, may amend or supplement this Indenture or the Notes without notice to
or consent of any Holder:


                                       67
<PAGE>

            (1) to cure any ambiguity, omission, defect or inconsistency;
      provided that such amendment or supplement does not, in the reasonable
      opinion of the Trustee, adversely affect the rights of any Holder in any
      material respect;

            (2) to comply with Article Five;

            (3) to provide for uncertificated Notes in addition to or in place
      of certificated Notes (provided that the uncertificated Notes are issued
      in registered form for purposes of Section 163(f) of the Code, or in a
      manner such that the uncertificated Notes are described in Section
      163(f)(2)(B) of the Code);

            (4) to comply with any requirements of the SEC in order to effect or
      maintain the qualification of this Indenture under the TIA;

            (5) to make any change that would provide any additional benefit or
      rights to the Holders or that does not adversely affect the rights of any
      Holder; or to surrender any right or power conferred upon the Company;

            (6) to add Subsidiary Guarantees with respect to the Notes;

            (7) to secure the Notes;

            (8) to make any other change that does not, in the reasonable
      opinion of the Trustee, adversely affect in any material respect the
      rights of any Holders hereunder; or

            (9) alter the provisions with respect to the mandatory redemption of
      the Notes or the redemption of the Notes at the option of the Company in a
      manner adverse to the Holders;

provided that the Company has delivered to the Trustee an Opinion of Counsel
stating that such amendment or supplement complies with the provisions of this
Section 9.01.

            After an amendment, supplement or waiver under this Section 9.01
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 amendment, supplement or
waiver.

            SECTION 9.02. With Consent of Holders.

            Subject to Section 6.07, the Company, when authorized by a Board
Resolution, and the Trustee, together, with the written consent of the Holder or
Holders of at least a majority in aggregate principal amount of the then
outstanding Notes, may amend or supplement this Indenture or the Notes, without
notice to any other Holders. Subject to Section 6.07, the Holder or Holders of
at least a majority in aggregate principal amount of the 


                                       68
<PAGE>

then outstanding Notes may waive compliance by the Company with any provision of
this Indenture or the Notes without notice to any other Holder. No amendment,
supplement or waiver, including a waiver pursuant to Section 6.04, shall,
without the consent of each Holder of each Note affected thereby:

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

            (2) reduce the rate of or extend the time for payment of interest on
      any Notes;

            (3) reduce the principal of or change or have the effect of changing
      the Stated Maturity of any Note, or alter the provisions with respect to
      the mandatory redemption of the Notes or the redemption of the Notes at
      the option of the Company in a manner adverse to the Holders;

            (4) waive a Default or Event of Default in the payment of principal
      of, premium, if any, or interest on, the Notes;

            (5) waive a mandatory redemption payment with respect to any Note;

            (6) make any Notes payable in money or payable in a place other than
      that stated in the Notes;

            (7) make any change in Section 6.04 or Section 6.07 or the second
      sentence of this Section;

            (8) amend, modify, change or waive any provision of this Section
      9.02;

            (9) modify Articles Ten or Twelve or the definitions used in
      Articles Ten or Twelve to adversely affect the Holders of the Notes; or

            (10) make any change in any Subsidiary Guarantee that would
      adversely affect the Holders.

            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 amendment, supplement or
waiver.

            SECTION 9.03. Effect on Senior Indebtedness.


                                       69
<PAGE>

            No amendment of this Indenture shall adversely affect the rights of
any holder of Senior Indebtedness of the Company or any Restricted Subsidiary
under Article Ten or Twelve of this Indenture, without the consent of such
holder (or its Representative).

            SECTION 9.04. Compliance with TIA.

            Every amendment, waiver or supplement of this Indenture or the Notes
shall comply with the TIA as then in effect.

            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 Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. Subject to the following paragraph, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note or portion of such Note by
notice to the Trustee or the Company received before the date the amendment,
supplement or waiver becomes effective.

            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 Holder, unless it makes a change described in any of clauses (1)
through (10) of Section 9.02, in which case, the amendment, supplement or waiver
shall bind only each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note; provided that any such waiver shall not impair or
affect the right of any Holder to receive payment of principal of and interest
on a Note, on or after the respective due dates expressed in such Note, 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 Notes.

            If an amendment, supplement or waiver changes the terms of a Note,
the Trustee may require the Holder of such Note to deliver it to the Trustee.
The Trustee may place an appropriate notation on the Note about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms.


                                       70
<PAGE>

Any such notation or exchange shall be made at the sole cost and expense of the
Company. Failure to make the appropriate notation or to issue a new Note shall
not affect the validity 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. Such Opinion of Counsel shall not be an expense of the Trustee.

            SECTION 9.08. Payment for Consent.

            Neither the Company nor any Affiliate of the Company shall, directly
or indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes, unless such consideration is offered to be paid to all Holders
that so consent, waive or agree to amend in the time frame set forth in
solicitation documents relating to such consent, waiver or agreement.

                                   ARTICLE TEN

                                  SUBORDINATION

            SECTION 10.01. Notes Subordinated to Senior Indebtedness.

            The Company covenants and agrees, and each Holder of the Notes, by
its acceptance thereof, likewise covenants and agrees, that all Notes shall be
issued subject to the provisions of this Article Ten; and each Person holding
any Note, whether upon original issue or upon transfer, assignment or exchange
thereof, accepts and agrees that the payment of all Obligations on the Notes by
the Company shall, to the extent and in the manner herein set forth, be
subordinated and junior in right of payment to the prior payment in full in cash
of all Senior Indebtedness of the Company; that the subordination is for the
benefit of, and shall be enforceable directly by, the holders of Senior
Indebtedness of the Company, and that each holder of Senior Indebtedness of the
Company whether now outstanding or hereafter created, incurred, assumed or
Guaranteed shall be deemed to have acquired Senior Indebtedness of the Company
in reliance upon the covenants and provisions contained in this Indenture and
the Notes. Only Indebtedness of the Company that is Senior Indebtedness of the
Company shall rank senior to the Notes in accordance with the provisions of the
Indenture. The Notes shall in all respects rank pari passu with all other Senior
Subordinated Indebtedness of the Company. Unsecured Indebtedness is not deemed
to be subordinated or junior to secured Indebtedness 


                                       71
<PAGE>

merely because it is unsecured. The terms of the subordination provisions
described in this Article Ten shall not apply to payments from money or the
proceeds of U.S. Government Obligations in trust by the Trustee for the payment
of principal and interest on the Notes pursuant to the provisions described in
Article Eight unless such payments were in violation of Designated Senior
Indebtedness.

            SECTION 10.02. No Payment on Notes in Certain Circumstances.

            (a) The Company may not, and no other Person on behalf of the
Company may pay principal of, premium (if any) or interest on the Notes or make
any other payments with respect to the Notes or make any deposit pursuant to the
provisions described under Article Eight above and may not repurchase, redeem or
otherwise retire any Notes (collectively, "pay the Notes") if (i) any amount of
principal, interest or other payments due under any Senior Indebtedness of the
Company has not been paid when due and remains outstanding or (ii) any other
default on Senior Indebtedness of the Company occurs and the maturity of such
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, the default has been cured or waived in writing and any such
acceleration has been rescinded or such Designated Senior Indebtedness has been
paid in full in cash, after which the Company shall resume making any and all
required payments in respect of the Notes, including any missed payments.
However, the Company may pay the Notes without regard to the foregoing if the
Company and the Trustee receive written notice approving such payment from the
Representative of the Senior Indebtedness of the Company with respect to which
either of the events set forth in clause (i) or (ii) of the immediately
preceding sentence has occurred and is continuing, after which the Company shall
resume making any and all required payments in respect of the Notes, including
any missed payments. During the continuance of any default (other than a default
described in clause (i) or (ii) of the second preceding sentence) with respect
to any Designated Senior Indebtedness of the Company pursuant to which the
maturity thereof may be accelerated either immediately without further notice
(except such notice as may be required to effect such acceleration) or upon the
expiration of any applicable grace periods, the Company may not pay the Notes
for a period (a "Payment Blockage Period") commencing upon the receipt by the
Trustee (with a copy to the Company) of written notice (a "Blockage Notice") of
such default from the Representative of the holders of such Designated Senior
Indebtedness of the Company specifying an election to effect a Payment Blockage
Period and ending 179 days thereafter (or earlier if such Payment Blockage
Period is terminated (A) by written notice to the Trustee and the Company from
the Person or Persons who gave such Blockage Notice, (B) because the default
giving rise to such Blockage Notice is no longer continuing (solely as evidenced
by written notice to the Trustee by the Representative of such Designated Senior
Indebtedness which notice shall be promptly delivered) or (C) because such
Designated Senior Indebtedness of the Company has been repaid in full in cash).
Notwithstanding the provisions described in the immediately preceding sentence
(but subject to the provisions contained in the first sentence of this
paragraph), unless the holders of such Designated Senior Indebtedness of the
Company or the Representative of such holders has accelerated the maturity of
such Designated Senior Indebtedness of the Company, the Company may resume
payments on the Notes after the end of such Payment Blockage Period, including
any missed payments. No more than one Payment Blockage Period may be commenced
in any consecutive 360-day period, irrespective of the number of 


                                       72
<PAGE>

defaults with respect to Designated Senior Indebtedness of the Company during
such period.

            (b) If, notwithstanding the foregoing, any payment shall be received
by the Trustee or any Holder when such payment is prohibited by Section
10.02(a), such payment shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of such Senior Indebtedness of the
Company (pro rata to such holders on the basis of the respective amount of such
Senior Indebtedness of the Company 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 Indebtedness of the Company, if any, received from the holders of such
Senior Indebtedness of the Company (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 Indebtedness of the Company.

            The provisions of this Section shall not apply to any payment with
respect to which Section 10.03 would be applicable.

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

            SECTION 10.03. Payment Over of Proceeds upon Dissolution, Etc.

marshaling of assets of the Company or any of its Subsidiaries or in a
bankruptcy, reorganization, insolvency, receivership or other similar proceeding
relating to the Company or any of its Subsidiaries or any of their property,
whether voluntary or involuntary, all Obligations due or to become due upon all
Senior Indebtedness of the Company shall first be paid in full in cash, or such
payment duly provided for to the satisfaction of the holders of Senior
Indebtedness of the Company, before any payment or distribution of any kind or
character is made on account of any Obligations on the Notes, or for the
acquisition of any of the Notes for cash or property or otherwise. 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, any payment or distribution of assets of the Company or any of its
Subsidiaries of any kind or character, whether in cash, property or securities,

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
Indebtedness


                                       73
<PAGE>

of the Company (pro rata to such holders on the basis of the respective amounts
of Senior Indebtedness of the Company held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Indebtedness of the Company may have been issued, as
their respective interests may appear, for application to the payment of Senior
Indebtedness of the Company remaining unpaid until all such Senior Indebtedness
of the Company has been paid in full in cash after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders of
Senior Indebtedness of the Company.

            (b) To the extent any payment of Senior Indebtedness of the Company
(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 other similar Person, the Senior
Indebtedness of the Company or part thereof originally intended to be satisfied
shall be deemed to be reinstated and outstanding as if such payment had not
occurred.

            (c) If, 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 or the Trustee 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 Indebtedness of the Company (pro rata to such holders
on the basis of the respective amount of Senior Indebtedness of the Company held
by such holders) or their respective Representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Indebtedness
of the Company may have been issued, as their respective interests may appear,
for application to the payment of Senior Indebtedness of the Company remaining
unpaid until all such Senior Indebtedness of the Company has been paid in full
in cash, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Indebtedness of the
Company.

            (d) The consolidation of the Company with, or the merger of the
Company with or into, another corporation or the liquidation or dissolution of
the Company 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 Senior
Indebtedness of the Company 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,


                                       74
<PAGE>

from making payments at any time for the purpose of making payments of principal
of and interest on the Notes, 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 Notes 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 the written notice provided for
in the third sentence of Section 10.02(a) or in Section 10.07 has been received
by the Trustee (provided that, notwithstanding the foregoing, such application
shall otherwise be subject to the provisions of the first sentence of Section
10.02(a), 10.02(b) 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.

            SECTION 10.05. Subrogation.

            Subject to, and only after, the payment in full in cash of all
Senior Indebtedness of the Company, the Holders of the Notes shall be subrogated
to the rights of the holders of Senior Indebtedness of the Company to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness of the Company until the Notes shall be
paid in full; and, for the purposes of such subrogation, no such payments or
distributions to the holders of the Senior Indebtedness of the Company 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 of the Notes, be deemed to be a payment by
the Company to or on account of the Senior Indebtedness of the Company, 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 of the Notes, on
the one hand, and the holders of the Senior Indebtedness of the Company, on the
other hand. If any payment or distribution to which the Holders would otherwise
have been entitled but for the application of the provisions of this Article
Ten, shall have been applied, pursuant to the provisions of this Article Ten, to
the payment of amounts payable under Senior Indebtedness of the Company, then
the Holders shall be entitled to receive from the holders of such Senior
Indebtedness any payments or distributions received by such holders of Senior
Indebtedness in excess of the amount sufficient to pay all amounts payable under
or in respect of such Senior Indebtedness in full in cash.

            SECTION 10.06. Obligations of the Company Unconditional.

            Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Notes or the Subsidiary Guarantees is intended to or shall impair, as
among the Company, its creditors other than the holders of Senior Indebtedness
of the Company, and the Holders, the obligation of the Company, which is
absolute and unconditional, to pay to the Holders the principal of, premium, if
any, and any interest on the Notes 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 Indebtedness of the Company, nor shall anything herein or
therein prevent the Holder of any Note or the Trustee on its behalf from
exercising all remedies otherwise permitted by 


                                       75
<PAGE>

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 Notes pursuant to the provisions of this
Article Ten. 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 Indebtedness of the Company 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 Indebtedness of the Company 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.

            If the Trustee determines in good faith that any evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness of the Company 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 Indebtedness of the Company 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
                           Liquidating 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 Notes 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 so long as such order gives effect to
the provisions of this Article Ten, or upon a certificate of the receiver,
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 of the Notes, for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness of the Company 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 Indebtedness.

            The Trustee and any agent of the Company or the Trustee shall be
entitled to all 


                                       76
<PAGE>

the rights set forth in this Article Ten with respect to any Senior Indebtedness
of the Company 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 Indebtedness of
the Company 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 Indebtedness of the Company,
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 Indebtedness of
the Company 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
Indebtedness of the Company.

            Whenever a distribution is to be made or a notice given to holders
or owners of Senior Indebtedness of the Company, the distribution may be made
and the notice may be given to their Representative, if any. The Company shall
provide the Trustee with the name and address of any Representative.

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

            No right of any present or future holders of any Senior Indebtedness
of the Company 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,
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 Indebtedness of the Company 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 Notes and without
impairing or releasing the subordination provided in this Article Ten or the
obligations hereunder of the Holders of the Notes to the holders of the Senior
Indebtedness of the Company, 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 Indebtedness of the Company, or otherwise amend or supplement in
any manner Senior Indebtedness of the Company, or any instrument evidencing the
same or any agreement under which Senior Indebtedness of the Company is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness of the Company;
(iii) release any Person liable in any manner for the payment or collection of
Senior Indebtedness of the Company; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

            SECTION 10.11. Noteholders Authorize Trustee To Effectuate
                           Subordination of Notes.

            Each Holder of Notes by its acceptance of them authorizes and
expressly directs


                                       77
<PAGE>

the Trustee on its behalf to take such action as may be necessary or appropriate
to effectuate, as between the holders of Senior Indebtedness of the Company and
the Holders of Notes, 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 creditors or
otherwise) tending towards liquidation of the business and assets of the
Company, the filing of a claim for the unpaid balance of its Notes 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 Indebtedness
of the Company or their Representatives 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 Notes, and the Trustee shall supply such
Holders and Representatives all information and documents they reasonably
request in order to file such claims. Nothing herein contained shall be deemed
to authorize the Trustee or the holders of Senior Indebtedness of the Company 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 Notes or the rights of any Holder thereof, or to authorize the
Trustee or the holders of Senior Indebtedness of the Company 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 Notes by reason of any provision of this Article Ten shall not be
construed as preventing the occurrence of an Event of Default.

            Nothing contained in this Article Ten shall limit the right of the
Trustee or the Holders to take any action or accelerate the maturity of the
Notes pursuant to Article Six or to pursue any rights or remedies hereunder or
under applicable law, subject to the rights, if any, under this Article Ten of
the holders from time to time, of Senior Indebtedness of the Company.

            SECTION 10.13. Trustee's Compensation Not Prejudiced.

            Nothing in this Article Ten shall apply to amounts due to the
Trustee pursuant to other sections in this Indenture

            SECTION 10.14. Acceleration of Payment of Notes.

            If payment of the Notes is accelerated because of an Event of
Default, the Company or the Trustee shall promptly notify the holders of
Designated Senior Indebtedness of the Company or the Representative of 
such holders of the acceleration (in the case of the Trustee, only to the extent
of its actual knowledge of such holders or the Representative of 

                                       78
<PAGE>

such holders). Such notice is in addition to, and not in lieu of, any notice 
that may be required to be delivered under Section 6.02 prior to the 
effectiveness of any such acceleration.

                                 ARTICLE ELEVEN

                              SUBSIDIARY GUARANTEES

            SECTION 11.01. Unconditional Subsidiary Guarantee.

            Each of the Subsidiary Guarantors hereby unconditionally jointly and
severally Guarantees (such Guarantee to be referred to herein as the "Subsidiary
Guarantee") to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, the Notes or the Obligations
of the Company hereunder or thereunder, that: (i) the principal of and interest
on the Notes shall be promptly paid in full when due, subject to any applicable
grace period, whether at maturity, by acceleration or otherwise and interest on
the overdue principal, if any, and interest on any interest, to the extent
lawful, of the Notes and all other Obligations of the Company to the Holders or
the Trustee hereunder or thereunder shall be promptly paid in full or performed,
all in accordance with the terms hereof and thereof; and (ii) in case of any
extension of time of payment or renewal of any Notes or of any 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, subject to any applicable
grace period, whether at stated maturity, by acceleration or otherwise.

            Each Subsidiary Guarantor further agrees that, as between such
Subsidiary Guarantor on one hand, and the Holders and the Trustee on the other
hand, (x) the maturity of the Obligations Guaranteed hereby may be accelerated
as provided in Article Six for the purposes of the Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations Guaranteed hereby, and (y) in the
event of any acceleration of such Obligations as provided in Article Six, such
Obligations (whether or not due and payable) shall forthwith become due and
payable by such Subsidiary Guarantor for the purposes of the Subsidiary
Guarantee.

            Each of the Subsidiary Guarantors hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a guarantor.
Each of the Subsidiary Guarantors hereby waives 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 the
Subsidiary Guarantee shall not be discharged except by complete performance of
the Obligations contained in the Notes, this Indenture and in the Subsidiary
Guarantee. If any Noteholder or the Trustee is required by any court or
otherwise to return to the Company, any Subsidiary Guarantor, or any custodian,
trustee, liquidator or 


                                       79
<PAGE>

other similar official acting in relation to the Company or any Subsidiary
Guarantor, any amount paid by the Company or such Subsidiary Guarantor to the
Trustee or such Noteholder, the Subsidiary Guarantee, to the extent theretofore
discharged, shall be reinstated in full force and effect. Each of the Subsidiary
Guarantors hereby agrees that, in the event of default in the payment of
principal (or premium, if any) or interest on such Notes, whether at their
Stated Maturity, by acceleration, called for redemption, purchase or otherwise,
legal proceedings may be instituted by the Trustee on behalf of, or by, the
Holder of such Notes, subject to the terms and conditions set forth in this
Indenture, directly against each of the Subsidiary Guarantors to enforce the
Subsidiary Guarantee without first proceeding against the Company. Each
Subsidiary Guarantor agrees that if, after the occurrence and during the
continuance of an Event of Default, the Trustee or any Holders are prevented by
applicable law from exercising their respective rights to accelerate the
maturity of the Notes, to collect interest on the Notes, or to enforce any other
right or remedy with respect to the Notes, the Subsidiary Guarantors agree to
pay to the Trustee for the account of the Holders, upon demand therefor, the
amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Trustee or any of the Holders.

            SECTION 11.02. Subordination of Subsidiary Guarantee.

            The obligations of each Subsidiary Guarantor to the Holders of the
Notes and to the Trustee pursuant to the Subsidiary Guarantee and this Indenture
are expressly subordinate and subject in right of payment to the prior payment
in full in cash of all Senior Indebtedness of such Subsidiary Guarantor, to the
extent and in the manner provided in Article Twelve.

            SECTION 11.03. Severability.

            In case any provision of the Subsidiary Guarantee shall be invalid,
illegal or unenforceable, the validity, legality, and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

            SECTION 11.04. Release of Subsidiary Guarantor from the Subsidiary
                           Guarantee.

            Upon the sale or disposition (whether by merger, stock purchase,
asset sale or otherwise) of a Subsidiary Guarantor (or all or substantially all
of its assets) to an entity which is not the Company or a Subsidiary or
Affiliate of the Company and which sale or disposition is otherwise in
compliance with the terms of this Indenture, including but not limited to the
provisions of Section 5.03, or pursuant to a foreclosure of a Lien that secures
outstanding Bank Indebtedness on the capital stock of such Subsidiary Guarantor
in accordance with the Credit Facility, such Subsidiary Guarantor shall be
deemed released from all obligations under this Article Eleven without any
further action required on the part of the Trustee or any Holder.

            The Trustee shall deliver an appropriate instrument evidencing such
release upon receipt of a request by the Company accompanied by an Officers'
Certificate and Opinion of Counsel certifying as to the compliance with this
Section 11.04.


                                       80

            SECTION 11.05. Limitation on Amount Guaranteed; Contribution by
                           Subsidiary Guarantors.

            (a) Anything contained in this Indenture or the Subsidiary Guarantee
to the contrary notwithstanding, if any Fraudulent Transfer Law (as hereinafter
defined) is determined by a court of competent jurisdiction to be applicable to
the obligations of any Subsidiary Guarantor under the Subsidiary Guarantee, such
obligations of such Subsidiary Guarantor under the Subsidiary Guarantee shall be
limited to a maximum aggregate amount equal to the largest amount that would not
render its obligations under the Subsidiary Guarantee subject to avoidance as a
fraudulent transfer or conveyance under Section 548 of Title 11 of the United
States Code or any applicable provisions of comparable state law (collectively,
the "Fraudulent Transfer Laws"), in each case after giving effect to all other
liabilities of such Subsidiary Guarantor, contingent or otherwise, that are
relevant under the Fraudulent Transfer Laws (specifically excluding, however,
any liabilities of such Subsidiary Guarantor (x) in respect of intercompany
Indebtedness to Company or other Affiliates of Company to the extent that such
Indebtedness would be discharged in an amount equal to the amount paid by such
Subsidiary Guarantor under the Subsidiary Guarantee and (y) under any Subsidiary
Guarantee of Subordinated Indebtedness which Subsidiary Guarantee contains a
limitation as to maximum amount similar to that set forth in this clause (a) of
Section 11.05, pursuant to which the liability of such Subsidiary Guarantor
under the Subsidiary Guarantee is included in the liabilities taken into account
in determining such maximum amount) and after giving effect as assets to the
value (as determined under the applicable provisions of the Fraudulent Transfer
Laws) of any rights to subrogation, reimbursement, indemnification or
contribution of such Subsidiary Guarantor pursuant to applicable law or pursuant
to the terms of any agreement (including without limitation any such right of
contribution under clause (b) of Section 11.05).

            (b) The Subsidiary Guarantors together desire to allocate among
themselves in a fair and equitable manner, their obligations arising under the
Subsidiary Guarantee. Accordingly, if any payment or distribution is made on any
date by any Subsidiary Guarantor under the Subsidiary Guarantee (a "Funding
Guarantor") that exceeds its Fair Share (as defined below) as of such date, that
Funding Guarantor shall be entitled to a contribution from each of the other
Subsidiary Guarantors in the amount of such other Subsidiary Guarantor's Fair
Share Shortfall (as defined below) as of such date, with the result that all
such contributions shall cause each Subsidiary Guarantor's Aggregate Payments
(as defined below) to equal its Fair Share as of such date. "Fair Share" means,
with respect to a Subsidiary Guarantor as of any date of determination, an
amount equal to (i) the ratio of (x) the Adjusted Maximum Amount (as defined
below) with respect to such Subsidiary Guarantor to (y) the aggregate of the
Adjusted Maximum Amounts with respect to all Subsidiary Guarantors, multiplied
by (ii) the aggregate amount paid or distributed on or before such date by all
Funding Guarantors under the Subsidiary Guarantee in respect of the obligations
guarantied. "Fair Share Shortfall" means, with respect to a Subsidiary Guarantor
as of any date of determination, the excess, if any, of the Fair Share of such
Subsidiary Guarantor over the Aggregate Payments of such Subsidiary Guarantor.
"Adjusted Maximum Amount" means, with respect to a Subsidiary Guarantor as of
any date of determination, the maximum aggregate amount of the obligations 


                                       81
<PAGE>

of such Subsidiary Guarantor under the Subsidiary Guarantee, determined as of
such date in accordance with clause (a) of Section 11.05; provided that, solely
for purposes of calculating the Adjusted Maximum Amount with respect to any
Subsidiary Guarantor for purposes of this clause (b) of Section 11.05, any
assets or liabilities of such Subsidiary Guarantor arising by virtue of any
rights to subrogation, reimbursement or indemnification or any rights to or
obligations of contribution hereunder shall not be considered as assets or
liabilities of such Subsidiary Guarantor. "Aggregate Payments" means, with
respect to a Subsidiary Guarantor as of any date of determination, an amount
equal to (i) the aggregate amount of all payments and distributions made on or
before such date by such Subsidiary Guarantor in respect of the Subsidiary
Guarantee (including, without limitation, in respect of this clause (b) of
Section 11.05 minus (ii) the aggregate amount of all payments received on or
before such date by such Subsidiary Guarantor from the other Subsidiary
Guarantors as contributions under this clause (b) of Section 11.05). The amounts
payable as contributions hereunder shall be determined as of the date on which
the related payment or distribution is made by the applicable Funding Guarantor.
The allocation among Subsidiary Guarantors of their obligations as set forth in
this clause (b) of Section 11.05 shall not be construed in any way to limit the
liability of any Subsidiary Guarantor under this Indenture or under the
Subsidiary Guarantee.

            SECTION 11.06. Waiver of Subrogation.

            Until payment in full is made of the Notes and all other obligations
of the Company to the Holders or the Trustee hereunder and under the Notes, each
Subsidiary Guarantor hereby irrevocably waives 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 such Subsidiary Guarantor's
obligations under the Subsidiary Guarantee and this Indenture, including without
limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Holder of Notes 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 any other manner, payment
or security on account of such claim or other rights. If any amount shall be
paid to any Subsidiary Guarantor in violation of the preceding sentence and the
Notes shall not have been paid in full, such amount shall have been deemed to
have been paid to such Subsidiary Guarantor for the benefit of, and held in
trust for the benefit of, the Holders of the Notes, and shall forthwith be paid
to the Trustee for the benefit of such Holders to be credited and applied upon
the Notes, whether matured or unmatured, in accordance with the terms of this
Indenture. Each Subsidiary Guarantor acknowledges that it shall receive direct
and indirect benefits from the financing arrangements contemplated by this
Indenture and that the waiver set forth in this Section 11.06 is knowingly made
in contemplation of such benefits.

            SECTION 11.07. Execution of Subsidiary Guarantee.

            To evidence its Guarantee to the Noteholders set forth in this
Article Eleven, each Subsidiary Guarantor hereby agrees to execute the
Subsidiary Guarantee in substantially the form included in Exhibit A, which
shall be endorsed on such Note ordered to be 


                                       82
<PAGE>

authenticated and delivered by the Trustee. Each Subsidiary Guarantor hereby
agrees that the Subsidiary Guarantee set forth in this Article Eleven shall
remain in full force and effect notwithstanding any failure to endorse on each
Note a notation of the Subsidiary Guarantee. The Subsidiary Guarantee shall be
signed on behalf of each Subsidiary Guarantor by one Officer (who shall have
been duly authorized by all requisite corporate actions) prior to the
authentication of the Note on which it is endorsed, and the delivery of such
Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Subsidiary Guarantee on behalf of such Subsidiary
Guarantor. Such signatures upon the Subsidiary Guarantee may be by manual or
facsimile signature of such officers and may be imprinted or otherwise
reproduced on the Subsidiary Guarantee, and in case any such Officer who shall
have signed the Subsidiary Guarantee shall cease to be such officer before the
Note on which the Subsidiary Guarantee is endorsed shall have been authenticated
and delivered by the Trustee or disposed of by the Company, such Note
nevertheless may be authenticated and delivered or disposed of as though the
person who signed the Subsidiary Guarantee had not ceased to be such Officer of
such Subsidiary Guarantor.

            SECTION 11.08. Waiver of Stay, Extension or Usury Laws.

            Each Subsidiary Guarantor jointly and severally covenants (to the
extent that it may lawfully do so) that it shall 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 such Subsidiary Guarantor from performing the Subsidiary Guarantee 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 Subsidiary Guarantor hereby expressly
waives all benefit or advantage of any such law, and covenants that it shall not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though
no such law had been enacted.

            SECTION 11.09. Effectiveness of Subsidiary Guarantee.

            The Subsidiary Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the Company
for liquidation or reorganization, should the Company become insolvent or make
an assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Notes, is,
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes, whether as a "voidable
preference," "fraudulent transfer," or otherwise, all as though such a payment
or performance had not been made. If any payments, or any part thereof, is
rescinded, reduced, restored or returned, the Notes shall, to the fullest extent
permitted by law, be reinstituted and deemed reduced only by such amount paid
and not so rescinded, reduced, restored or returned.

                                 ARTICLE TWELVE

                     SUBORDINATION OF GUARANTEE OBLIGATIONS

            SECTION 12.01. Guarantee Obligations Subordinated to Senior
                           Indebtedness of Subsidiary Guarantors.

            Each Subsidiary Guarantor covenants and agrees, and each Holder of
the Notes, by its acceptance thereof, likewise covenants and agrees, that any
payment of obligations by each Subsidiary Guarantor in respect of the Subsidiary
Guarantee (its "Guarantee Obligations") shall be made subject to the provisions
of this Article Twelve, and each Person holding any Note, whether upon original
issue or upon transfer, assignment or exchange thereof, accepts and agrees that
the payment of all such Subsidiary Guarantor's Guarantee Obligations shall, to
the extent and in the manner herein set forth, be subordinated and junior in
right of payment to the prior payment in full in cash of all Obligations in
respect of such Subsidiary Guarantor's Senior Indebtedness, including principal,
premium (if any) or interest (including post-petition interest) thereon, that
the subordination is for the benefit of, and shall be enforceable directly by,
the holders of such Subsidiary Guarantor's Senior Indebtedness, and that each
holder of any Subsidiary Guarantor's Senior Indebtedness whether now outstanding
or hereafter created, incurred, assumed or Guaranteed shall be deemed to have
acquired such Subsidiary Guarantor's Senior Indebtedness in reliance upon the
covenants and provisions contained in this Indenture and the Notes. Only
Indebtedness of a Subsidiary Guarantor that is Senior Indebtedness of such
Subsidiary Guarantor shall rank senior to the Subsidiary Guarantee of such
Subsidiary Guarantor in accordance with the provisions of this Indenture. A
Subsidiary Guarantee shall in all respects rank pari passu with all other Senior
Subordinated Indebtedness of the Subsidiary Guarantor to which it relates.
Unsecured Indebtedness is not deemed to be subordinated or junior to secured
Indebtedness merely because it is unsecured.

            SECTION 12.02. No Payment on Notes in Certain Circumstances.

            (a) No Subsidiary Guarantor may, and no other Person on behalf of
such Subsidiary Guarantor may, make any payment with respect to the Subsidiary
Guarantee or make any deposit pursuant to Article Eight above (collectively,
"pay the Subsidiary Guarantee") if (i) any amount of principal, interest or
other payments due under any Senior Indebtedness of such Subsidiary Guarantor or
the Company has not been paid when due whether at maturity, upon redemption, by
declaration or otherwise or (ii) any other default on Senior Indebtedness of
such Subsidiary Guarantor or the Company occurs and the maturity of such Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
the default has been cured or waived in writing and any such acceleration has
been rescinded or such Senior Indebtedness has been paid in full in cash, after
which such Subsidiary Guarantor shall resume making any and all required
payments in respect of the Subsidiary Guarantee, including any missed payments.
However, a Subsidiary Guarantor may pay the Subsidiary Guarantee without regard
to the foregoing if such Subsidiary Guarantor and the Trustee receive written
notice approving such payment from the Representative of the Senior Indebtedness
Guaranteed by such Subsidiary Guarantor with respect to which either of the
events set forth in clause (i) or (ii) of the immediately preceding sentence has
occurred and is continuing, after which such Subsidiary Guarantor shall resume
making any and all required payments in 


                                       84
<PAGE>

respect of the Subsidiary Guarantee, including any missed payments. During the
continuance of any default (other than a default described in clause (i) or (ii)
of the second preceding sentence) with respect to any Designated Senior
Indebtedness of a Subsidiary Guarantor or the Company pursuant to which the
maturity thereof may be accelerated either immediately without further notice
(except such notice as may be required to effect such acceleration) or upon the
expiration of any applicable grace periods, such Subsidiary Guarantor may not
pay the Subsidiary Guarantee for a period (a "Payment Blockage Period")
commencing upon the receipt by the Trustee (with a copy to such Subsidiary
Guarantor) of written notice (a "Blockage Notice") of such default from the
Representative of the holders of such Designated Senior Indebtedness of such
Subsidiary Guarantor or the Company specifying an election to effect a Payment
Blockage Period and ending 179 days thereafter (or earlier if such Payment
Blockage Period is terminated (A) by written notice to the Trustee and such
Subsidiary Guarantor from the Person or Persons who gave such Blockage Notice,
(B) because the default giving rise to such Blockage Notice is no longer
continuing (solely as evidenced by written notice to the Trustee by the
Representative of such Designated Senior Indebtedness which notice shall be
promptly delivered) or (C) because such Designated Senior Indebtedness of such
Subsidiary Guarantor and the related Designated Senior Indebtedness of the
Company has been repaid in full in cash). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this paragraph), unless the holders of such
Designated Senior Indebtedness of such Subsidiary Guarantor or the Company or
the Representative of such holders has accelerated the maturity of such
Designated Senior Indebtedness of such Subsidiary Guarantor or the Company, such
Subsidiary Guarantor may resume payments on the Subsidiary Guarantee after the
end of such Payment Blockage Period including any missed payments. No more than
one Payment Blockage Period may be commenced in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness Guaranteed by such Subsidiary Guarantor during such period.

            (b) If, notwithstanding the foregoing, any payment shall be received
by the Trustee or any Holder when such payment is prohibited by Section
12.02(a), such payment shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of such Guarantor's Senior Indebtedness
(pro rata to such holders on the basis of the respective amount of such
Subsidiary Guarantor's Senior Indebtedness 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 such Subsidiary Guarantor's Senior Indebtedness, if any, received from
the holders of such Subsidiary Guarantor's Senior Indebtedness (or their
Representatives) or, if such information is not received from such holders or
their Representatives, from such Subsidiary Guarantor and only amounts included
in the information provided to the Trustee shall be paid to the holders of such
Subsidiary Guarantor's Senior Indebtedness.

            The provisions of this Section shall not apply to any payment with
respect to which Section 12.03 would be applicable.

            Nothing contained in this Article Twelve shall limit the right of
the Trustee or the Holders of Notes to take any action to accelerate the
maturity of the Notes pursuant to 


                                       85
<PAGE>

Section 6.02 or to pursue any rights or remedies hereunder; provided that all
Senior Indebtedness of the Company thereafter due or declared to be due shall
first be paid in full in cash or before the Holders are entitled to receive any
payment of any kind or character with respect to Obligations on the Notes.

            SECTION 12.03. Payment Over of Proceeds upon Dissolution, Etc.

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

            (b) To the extent any payment of any Subsidiary Guarantor's Senior
Indebtedness (whether by or on behalf of such Subsidiary 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, such
Subsidiary Guarantor's Senior Indebtedness or part thereof originally intended
to be satisfied shall be deemed to be 


                                       86
<PAGE>

reinstated and outstanding as if such payment had not occurred.

            (c) If, notwithstanding the foregoing, any payment or distribution
of assets of any Subsidiary Guarantor of any kind or character, whether in cash,
property or securities, shall be received by any Holder or the Trustee when such
payment or distribution is prohibited by this Section 12.03, such payment or
distribution shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of such Subsidiary Guarantor's Senior Indebtedness
(pro rata to such holders on the basis of the respective amount of such
Subsidiary Guarantor's Senior Indebtedness held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Subsidiary Guarantor's Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of such Subsidiary Guarantor's Senior Indebtedness remaining unpaid
until all such Subsidiary Guarantor's Senior Indebtedness has been paid in full
in cash, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Subsidiary Guarantor's Senior
Indebtedness.

            (d) The consolidation of any Subsidiary Guarantor with, or the
merger of any Subsidiary Guarantor with or into, another corporation or the
liquidation or dissolution of any Subsidiary 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 such Subsidiary Guarantor's Senior Indebtedness
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 such Subsidiary
Guarantor's obligations 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 Subsidiary 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 in respect of this Subsidiary Guarantee,
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 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 the written notice provided
for in the third sentence of Section 12.02(a) or in Section 12.07 has been
received by the Trustee (provided that, notwithstanding the foregoing, such
application shall otherwise be subject to the provisions of the first sentence
of Section 12.02(a), 12.02(b) and Section 12.03). Each Subsidiary Guarantor
shall give prompt written notice to the Trustee of any dissolution, winding-up,
liquidation or reorganization of such Subsidiary Guarantor.

            SECTION 12.05. Subrogation.

            Subject to, and only after, the payment in full in cash of all
Subsidiary 



                                       87
 
<PAGE>

Guarantor Senior Indebtedness, the Holders of the Obligations of any Subsidiary
Guarantor shall be subrogated to the rights of the holders of such Subsidiary
Guarantor's Senior Indebtedness to receive payments or distributions of cash,
property or securities of such Subsidiary Guarantor applicable to such
Subsidiary Guarantor's Senior Indebtedness until the Obligations of such
Subsidiary Guarantor under the Subsidiary Guarantee shall be paid in full; and,
for the purposes of such subrogation, no such payments or distributions to the
holders of such Subsidiary Guarantor's Senior Indebtedness by or on behalf of
such Subsidiary 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 Subsidiary Guarantor and the Holders of such Subsidiary Guarantor's
Obligations, be deemed to be a payment by such Subsidiary Guarantor to or on
account of such Subsidiary Guarantor's Senior Indebtedness, 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 of such Subsidiary
Guarantor's Obligations, on the one hand, and the holders of such Subsidiary
Guarantor's Senior Indebtedness, on the other hand.

            If any payment or distribution to which the Holders would otherwise
have been entitled but for the application of the provisions of this Article
Twelve shall have been applied, pursuant to the provisions of this Article
Twelve, to the payment of amounts payable under Senior Indebtedness of any
Subsidiary Guarantor, then the Holders shall be entitled to receive from the
holders of such Senior Indebtedness any payments or distributions received by
such holders of Senior Indebtedness in excess of the amount sufficient to pay
all amounts payable under or in respect of such Senior Indebtedness in full in
cash.

            SECTION 12.06. Obligations of Subsidiary Guarantor Unconditional.

            Nothing contained in this Article Twelve or elsewhere in this
Indenture or in the Notes is intended to or shall impair, as among the
Subsidiary Guarantors, their respective creditors other than the holders of such
Subsidiary Guarantor's Senior Indebtedness, and the Holders, the obligation of
such Subsidiary Guarantor, which is absolute and unconditional, to pay to the
Holders the Guarantee Obligations 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 such Subsidiary Guarantor other
than the holders of such Subsidiary Guarantor's Senior Indebtedness, nor shall
anything herein or therein prevent the Holder of any Note 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 such Subsidiary Guarantor received upon the exercise
of any such remedy.

            SECTION 12.07. Notice to Trustee.

            Each Subsidiary Guarantor shall give prompt written notice to the
Trustee of any fact known to such Subsidiary Guarantor which would prohibit the
making of any payment to or by the Trustee in respect of the Subsidiary
Guarantee or the Notes pursuant to the provisions of this Article Twelve.
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 Subsidiary
Guarantor's 


                                       88
<PAGE>

Senior Indebtedness 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 such Subsidiary Guarantor or from a holder of such
Subsidiary Guarantor's Senior Indebtedness 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.

            If the Trustee determines in good faith that any evidence is
required with respect to the right of any Person as a holder of such Subsidiary
Guarantor's Senior Indebtedness 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 such
Subsidiary Guarantor's Senior Indebtedness 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 or distribution of assets of any Subsidiary
Guarantor referred to in this Article Twelve, the Trustee, subject to the
provisions of Article Seven hereof, and the Holders of the Notes 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
so long as such order gives effect to the provisions of this Article Twelve, or
upon a certificate of the receiver, 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 of the
Notes, for the purpose of ascertaining the persons entitled to participate in
such payment or distribution, the holders of each Subsidiary Guarantor's Senior
Indebtedness and other Indebtedness of any Subsidiary Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Twelve.

            SECTION 12.09. Trustee's Relation to Subsidiary Guarantor's Senior
                           Indebtedness.

            The Trustee, any agent of the Trustee and any agent of any
Subsidiary Guarantor shall be entitled to all the rights set forth in this
Article Twelve with respect to the respective Subsidiary Guarantor's Senior
Indebtedness 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 the respective Subsidiary
Guarantor's Senior Indebtedness 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 the respective Subsidiary Guarantor's
Senior Indebtedness, the Trustee undertakes to perform or to observe only such
of its covenants and 


                                       89
<PAGE>

obligations as are specifically set forth in this Article Twelve, and no implied
covenants or obligations with respect to the holders of the respective
Subsidiary Guarantor's Senior Indebtedness shall be read into this Indenture
against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders of any Subsidiary Guarantor's Senior Indebtedness.

            Whenever a distribution is to be made or a notice given to holders
or owners of any Subsidiary Guarantor's Senior Indebtedness, 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 Subsidiary Guarantors or Holders of 
                           Subsidiary Guarantors' Senior Indebtedness.

            No right of any present or future holders of any Subsidiary
Guarantor's Senior Indebtedness 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 such Subsidiary Guarantor or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by such Subsidiary
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 any Subsidiary Guarantor's Senior Indebtedness 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 Notes and
without impairing or releasing the subordination provided in this Article Twelve
or the obligations hereunder of the Holders of the Notes to the holders of such
Subsidiary Guarantor's Senior Indebtedness, 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, such Subsidiary Guarantor's Senior Indebtedness, or
otherwise amend or supplement in any manner such Subsidiary Guarantor's Senior
Indebtedness, or any instrument evidencing the same or any agreement under which
such Subsidiary Guarantor's Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Subsidiary Guarantor's Senior Indebtedness; (iii)
release any Person liable in any manner for the payment or collection of such
Subsidiary Guarantor's Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against such Subsidiary Guarantor and any other Person.

            SECTION 12.11. Noteholders Authorize Trustee To Effectuate
                           Subordination of Notes.

            Each Holder of Notes 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 each
Subsidiary Guarantor's Senior Indebtedness and the Holders of Notes, the

of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee or the holders of

contained in this Article Twelve shall limit the right of the Trustee or the
Holders to take any action or accelerate the maturity of the Notes pursuant to
Article Six or to pursue any rights or remedies hereunder or under applicable

law, subject to the rights, if any, under this Article Twelve of the holders

executed by the Company and authenticated by the Trustee as hereinafter

            (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a

            The Company shall execute and the Trustee shall, in accordance with
this Section 2.1(b), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depositary for such
Global Security or Global Securities or the nominee of such Depositary and (b)
shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instructions or held by the Trustee as custodian for the
Depositary.

            Members of, or participants in, the Depositary ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary or by the Trustee as the custodian of the
Depositary or under such Global Security, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such 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 Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a

      2.3 Transfer and Exchange.

            (a) Transfer and Exchange of Global Securities.

                  (i) The transfer and exchange of Global Securities or
      beneficial interests therein shall be effected through the Depositary, in
      accordance with this Indenture (including applicable restrictions on
      transfer set forth herein, if any) and the procedures of the Depositary
      therefor. A transferor of a beneficial interest in a Global Security shall
      deliver to the Registrar a written order given in accordance with the
      Depositary's procedures containing information regarding the participant
      account of the Depositary to be credited with a beneficial interest in the
      Global Security. The Registrar shall, in accordance with such
      instructions, instruct the Depositary to credit to the account of the
      Person specified in such instructions a beneficial interest in the Global
      Security and to debit the account of the Person making the transfer the
      beneficial interest in the Global Security being transferred.

                  (ii) Notwithstanding any other provisions of this Appendix
      (other than the provisions set forth in Section 2.5 of this Appendix), a
      Global Security may not be transferred as a whole except by the Depositary
      to a nominee of the Depositary or by a nominee of the Depositary to the
      Depositary or another nominee of the Depositary or by the Depositary or
      any such nominee to a successor Depositary or a nominee of such successor
      Depositary.

                  (iii) In the event that a Global Security is exchanged for
      Securities in definitive registered form pursuant to Section 2.5 of this
      Appendix or Section 2.10 of this Indenture, prior to the consummation of a
      Registered Exchange Offer or the effectiveness of a Registration Statement
      with respect to such Securities, such Securities may be exchanged only in
      accordance with such procedures as are substantially consistent with the
      provisions of this Section 2.3 (including the certification requirements
      set forth on the reverse of the Initial Notes intended to ensure that such
      transfers comply with Rule 144A or Regulation S, as the case may be) and
      such other procedures as may from time to time be adopted by the Company.

            (b) Legend.

            "THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
            TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES
            SECURITIES ACT OF 1933 (THE "SECURITIES ACT"), AND THIS NOTE MAY NOT
            BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF
            SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH
            PURCHASER OF THIS NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS
            NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION
            5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

            "THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE ISSUER THAT
            (A) THIS NOTE MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
            ONLY (i) INSIDE THE UNITED STATES TO A PERSON WHOM THE SELLER
            REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
            IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE
            REQUIREMENTS OF RULE 144A, (ii) OUTSIDE THE UNITED STATES IN A
            TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT,
            (iii) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE
            SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR
            (iv) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
            SECURITIES ACT, IN EACH OF CASES (i) THROUGH (iv) IN ACCORDANCE WITH
            ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES,
            AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO,
            NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS
            REFERRED TO IN (A) ABOVE."

                  (ii) Upon any sale or transfer of a Transfer Restricted
      Security (including any Transfer Restricted Security represented by a
      Global Security) pursuant to Rule 144 under the Securities Act, the
      Registrar shall permit the Holder thereof to exchange such Transfer
      Restricted Security for such Security without the restricted securities
      legend set forth on Exhibit 1 hereto that does not bear the legend set
      forth above and rescind any restriction on the transfer of such Transfer
      Restricted Security, if 


                                        V
<PAGE>

      the Holder certifies in writing to the Registrar that its request for such
      exchange was made in reliance on Rule 144 (such certification to be in the
      form set forth on the reverse of the Security).

                  (iii) After a transfer of any Initial Notes or Private
      Exchange Notes during the period of the effectiveness of a Registration
      Statement or a Shelf Registration Statement with respect to Initial Notes
      or Private Exchange Notes, as the case may be, all requirements pertaining
      to legends on such Initial Notes or such Private Exchange Notes shall
      cease to apply so long as such Initial Notes or such Private Exchange
      Notes were transferred pursuant to such Registration Statement, but the
      requirements requiring such Initial Notes or such Private Exchange Notes
      issued to certain Holders be issued in global form will continue to apply,
      and Initial Notes or Private Exchange Notes in global form without legends
      will be available to the transferee of the Holder of such Initial Notes or
      Private Exchange Notes upon exchange of such transferring Holder's Initial
      Notes or Private Exchange Notes or directions to transfer such Holder's
      interest in the Global Security, as applicable.

                  (iv) Upon the consummation of a Registered Exchange Offer with
      respect to the Initial Notes pursuant to which Holders of such Initial
      Notes are offered Exchange Notes in exchange for their Initial Notes, all
      requirements pertaining to such Initial Notes that Initial Notes issued to
      certain Holders be issued in global form will continue to apply and
      Initial Notes in global form with the restricted securities legend set
      forth in Exhibit 1 hereto will be available to Holders of such Initial
      Notes that do not exchange their Initial Notes, and Exchange Notes in
      global form without the restricted securities legend set forth in Exhibit
      1 hereto will be available to Holders that exchange such Initial Notes in
      such Registered Exchange Offer.

                  (v) Upon the consummation of a Private Exchange with respect
      to the Initial Notes pursuant to which Holders of such Initial Notes are
      offered Private Exchange Notes in exchange for their Initial Notes, all
      requirements pertaining to such Initial Notes that Initial Notes issued to
      certain Holders be issued in global form will still apply, and Private
      Exchange Notes in global form with the restricted securities legend set
      forth in Exhibit 1 hereto will be available to Holders that exchange such
      Initial Notes in such Private Exchange.

            (c) Cancellation or Adjustment of Global Security. At such time as
all beneficial interests in a Global Security have either been exchanged for
certificated Securities, redeemed, repurchased or canceled, such Global Security
shall be returned to the Depositary for cancellation or retained and canceled by
the Trustee. At any time prior to such cancellation, if any beneficial interest
in a Global Security is exchanged for certificated Securities, redeemed,
repurchased or canceled, the principal amount of Securities represented by such
Global Security shall be reduced and an adjustment shall be made on the books
and records of the Trustee (if it is then the Securities Custodian for such
Global Security) with respect to such Global Security, by the Trustee or the
Securities Custodian, to reflect such reduction.

                              (REVERSE OF SECURITY)

                      13% SENIOR SUBORDINATED NOTE DUE 2008

            1. Interest. ENVIRONMENTAL SYSTEMS PRODUCTS HOLDINGS INC., a
Delaware corporation (the "Company"), promises to pay to the registered holder
of this Note interest on the principal amount of this Note at the rate per annum
shown above. Interest on the Notes shall accrue from the most recent date on
which interest has been paid or, if no interest has been paid, from October 16,
1998. The Company shall pay interest semi-annually in arrears on each Interest
Payment Date, commencing April 30, 1999. For U.S. federal income tax purposes,
the "issue price" of the Notes shall be less than the aggregate principal amount
to the extent of the fair market value of the common stock of Holdco acquired in
connection with the purchase of the Notes. To the extent of such difference,
"original issue discount" ("OID") shall be recognized by a Holder during such
Holder's ownership of the Notes. Interest shall be computed on the basis of a
360-day year of twelve 30-day months.

            The Company shall pay interest on overdue principal at the rate
borne by the Notes plus 1% per annum and on overdue installments of interest
(without regard to any applicable grace periods) at such higher rate to the
extent lawful.

            2. Method of Payment. The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date immediately preceding the Interest Payment
Date even if the Notes are cancelled on registration of transfer or registration
of exchange after such Record Date. Holders must surrender Notes to a Paying
Agent to collect principal payments. The Company shall pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by its check payable in such U.S.
Legal Tender. The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

            3. Paying Agent and Registrar. Initially, the Trustee (as defined
below) shall act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-Registrar without notice to the Holders.

            4. Indenture and Subsidiary Guarantee. The Company issued the Notes
under an Indenture, dated as of October 16, 1998 (the "Indenture"), among the
Company, the Subsidiary Guarantors named therein, Holdco and United States Trust
Company of Texas, N.A., as trustee (the "Trustee"). This Note is one of a duly
authorized issue of Initial Notes of the Company designated as its 13% Senior
Subordinated Notes due 2008 (the "Initial Notes"). The Notes are limited in
aggregate principal amount to $100,000,000. The Notes include the Initial Notes,
the Private Exchange Notes and the Exchange Notes issued in 


                                      A-4
<PAGE>

exchange for the Initial Notes pursuant to the Indenture. The Initial Notes, the
Private Exchange Notes and the Exchange Notes are treated as a single class of
securities under the Indenture. Capitalized terms herein are used as defined in
the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA"), as in effect on the date of the Indenture. Notwithstanding anything to
the contrary herein, the Notes are subject to all such terms, and Holders of
Notes are referred to the Indenture and the TIA Act for a statement of them. The
Notes are unsecured senior subordinated obligations of the Company. Payment on
each Note is Guaranteed on a senior subordinated basis by the Subsidiary
Guarantors pursuant to Article Eleven of the Indenture. To the extent of any
conflict between the terms of the Notes and the Indenture, the applicable terms
of the Indenture shall govern.

            5. Subordination. The Notes are subordinated in right of payment, in
the manner and to the extent set forth in the Indenture, to the prior payment in
full in cash of all Senior Indebtedness of the Company, whether outstanding on
the date of the Indenture or thereafter created, incurred, assumed or
Guaranteed. The obligations of each Subsidiary Guarantor pursuant to its
Subsidiary Guarantee and the terms of the Indenture are subordinated in right of
payment to the prior payment in full in cash of all Senior Indebtedness of such
Subsidiary Guarantor to the extent set forth in the Indenture. Each Holder by
his acceptance hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on his behalf, to take such action as may be
necessary or appropriate to effectuate the subordination provided for in the
Indenture and appoints the Trustee his attorney-in-fact for such purposes.

            6. Redemption.

            (a) Optional Redemption. Except as set forth in the following
paragraph, the Notes shall not be redeemable at the option of the Company prior
to October 31, 2003. Thereafter, the Notes shall be redeemable, at the Company's
option, in whole or in part, at any time or from time to time, upon not less
than 30 nor more than 60 days' prior notice mailed by first-class mail to each
Holder's registered address, at the following redemption prices (expressed in
percentages of principal amount), plus accrued and unpaid interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if

at any time and from time to time prior to October 31, 2001, the Company may
redeem in the aggregate up to 35% of the original principal amount of the Notes
with the Net Cash Proceeds of one or more Public Equity Offerings, at a
redemption price (expressed as a percentage of principal amount) of 113% plus
accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that at least 65% of the aggregate
principal amount of the Notes originally outstanding must remain outstanding
after each such redemption.

            In order to effect the foregoing redemption with the proceeds of any
Public Equity Offering, the Company shall make such redemption not more than 120
days after the consummation of any such Public Equity Offering.

            7. Notice of Redemption. Notice of redemption shall be mailed at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Notes to be redeemed at such Holder's registered address. Notes in
denominations of $1,000 may be redeemed only in whole. Notes in denominations
larger than $1,000 may be redeemed in part but only in multiples of $1,000.

            Except as set forth in the Indenture, if monies for the redemption
of the Notes called for redemption shall have been deposited with the Paying
Agent for redemption on such Redemption Date, then, unless the Company defaults
in the payment of such Redemption Price plus accrued and unpaid interest, if
any, the Notes called for redemption shall cease to bear interest from and after
such Redemption Date and the only right of the Holders of such Notes shall be to
receive payment of the Redemption Price plus accrued and unpaid interest, if
any.

            8. Offers to Purchase. Sections 4.16 and 4.17 of the Indenture
provide that, in the event of certain Asset Dispositions (as defined in the
Indenture) and upon the occurrence of a Change of Control (as defined in the
Indenture), and subject to further limitations contained therein, the Company
shall make an offer to purchase certain amounts of the Notes in accordance with
the procedures set forth in the Indenture.

            9. Registration Rights. Pursuant to the Registration Rights
Agreement (as defined in the Indenture), under certain circumstances, (i) the
Company shall be obligated to consummate an exchange offer pursuant to which the
Holder of this Note shall have the right to exchange this Note for the Company's
13% Senior Subordinated Exchange Notes due 2008 (the "Exchange Notes") which
shall have been registered under the Securities Act or the Company's 13% Senior
Subordinated Private Exchange Notes due 2008 (the "Private Exchange Notes"), in
each case in like principal amount and having terms identical in all material

Holder shall register the transfer of or exchange of Notes in accordance with
the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay certain
transfer taxes or similar governmental charges payable in connection therewith
as permitted by the Indenture. The Registrar need not register the transfer of
or exchange of any Notes or portions thereof selected for redemption (except, in
the case of Notes to be redeemed in part, the portion of such Notes not to be
redeemed) or any Note for a period beginning 15 Business Days before the mailing
of a notice of an offer to repurchase or a notice of redemption or 15 Business
Days before any Interest Payment Date.

            11. Persons Deemed Owners. The registered Holder of a Note shall be
treated as the owner of it for all purposes.

            12. Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent shall
pay the money back to the Company (subject to any applicable abandoned property
law). After that, all liability of the Trustee and such Paying Agent with
respect to such money shall cease.

            13. Discharge Prior to Redemption or Maturity. If the Company at any
time deposits with the Trustee U.S. Legal Tender or U.S. Government Obligations
sufficient to pay the principal of and interest on the Notes to redemption or
maturity and complies with the other provisions of the Indenture relating
thereto, the Company shall be discharged from certain provisions of the
Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest on the Notes).

            14. Amendment; Supplement; Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the written
consent of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding, and any existing Default or Event of Default or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in aggregate principal amount of the Notes then

ambiguity, omission, defect or inconsistency, provide for uncertificated Notes
in addition to or in place of certificated Notes, or comply with Article Five of

            16. Successors. When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor shall be released from those obligations.

            17. Defaults and Remedies. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Notes then outstanding may declare all the Notes to be due and payable
in the manner, at the time and with the effect provided in the Indenture.

result in the Notes being due and payable immediately upon the occurrence of
such Events of Default. Holders of Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. The Trustee is not obligated to
enforce the Indenture or the Notes unless it has received indemnity reasonably
satisfactory to it. The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the
Notes then outstanding to direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of Notes notice of any continuing
Default or Event of Default (except a Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

            18. Trustee Dealings with Company. The Trustee under the Indenture,
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

            19. No Recourse Against Others. No stockholder, director, officer,
em ployee or incorporator, as such, of the Company or any Subsidiary Guarantor
shall have any liability for any obligation of the Company under the Notes or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of a Note by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

            20. Authentication. This Note shall not be valid until the Trustee
or Authenticating Agent manually signs the certificate of authentication on this
Note.

            21. Governing Law. The Laws of the State of New York shall govern
this Note and the Indenture (and the Guarantees relating thereto), without
regard to principles of conflict of laws.

            22. Abbreviations and Defined Terms. Customary abbreviations may be

            23. CUSIP Numbers. Pursuant to a recommendation promulgated by the

                              (REVERSE OF SECURITY)

                      13% SENIOR SUBORDINATED NOTE DUE 2008

            1. Interest. ENVIRONMENTAL SYSTEMS PRODUCTS HOLDINGS INC., a
Delaware corporation (the "Company"), promises to pay to the registered holder
of this Note interest on the principal amount of this Note at the rate per annum
shown above. Interest on the Notes will accrue from the most recent date on
which interest has been paid or, if no interest has been paid, from October 16,
1998. The Company will pay interest semi-annually in arrears on each Interest
Payment Date, commencing April 30, 1999. For U.S. federal income tax purposes,
the "issue price" of the Notes shall be less than the aggregate principal amount
to the extent of the fair market value of the common stock of Holdco acquired in
connection with the purchase of the Notes. To the extent of such difference,
"original issue discount" ("OID") shall be recognized by a Holder during such
Holder's ownership of the Notes. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

            The Company shall pay interest on overdue principal at the rate
borne by the Notes plus 1% per annum and on overdue installments of interest
(without regard to any applicable grace periods) at such higher rate to the
extent lawful.

            2. Method of Payment. The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date immediately preceding the Interest Payment
Date even if the Notes are cancelled on registration of transfer or registration
of exchange after such Record Date. Holders must surrender Notes to a Paying
Agent to collect principal payments. The Company shall pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by its check payable in such U.S.
Legal Tender. The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

            3. Paying Agent and Registrar. Initially, United States Trust
Company of Texas, N.A., as trustee (the "Trustee") will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders.

            4. Indenture and Guarantee. The Company issued the Notes under an
Indenture, dated as of October 16, 1998 (the "Indenture"), among the Company,
the Subsidiary Guarantors named therein and the Trustee. [This Note is one of a
duly authorized issue of Exchange Notes of the Company designated as its 13%
Senior Subordinated Exchange Notes due 2008 (the "Exchange Notes").] [This Note
is one of a duly authorized issue of Private Exchange Notes of the Company
designated as its 13% Senior Subordinated Private Exchange Notes due 2008 (the
"Private Exchange Notes").] The Notes are limited in aggregate principal amount
to $100,000,000. The Notes include the Initial Notes (the 13% Senior
Subordinated Notes due


                                       B-3
<PAGE>

2008) and the Private Exchange Notes and the Exchange Notes issued in 
exchange for the Initial Notes pursuant to the Indenture. The Initial Notes, 
the Private Exchange Notes and the Exchange Notes are treated as a single 
class of securities under the Indenture. Capitalized terms herein are used as 
defined in the Indenture unless otherwise defined herein. The terms of the 
Notes include those stated in the Indenture and those made part of the 
Indenture by reference to the TIA of 1939 (15 U.S. Code Sections 
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture. 
Notwithstanding anything to the contrary herein, the Notes are subject to all 
such terms, and Holders of Notes are referred to the Indenture and the TIA 
for a statement of them. The Notes are general unsecured obligations of the 
Company. Payment on each Note is guaranteed on a senior subordinated basis by 
the Subsidiary Guarantors pursuant to Article Eleven of the Indenture. To the 
extent of any conflict between the terms of the Notes and the Indenture, the 
applicable terms of the Indenture shall govern.

            5. Subordination. The Notes are subordinated in right of payment, in
the manner and to the extent set forth in the Indenture, to the prior payment in
full in cash of all Senior Indebtedness of the Company, whether outstanding on
the date of the Indenture or thereafter created, incurred, assumed or
guaranteed. The obligations of each Subsidiary Guarantor pursuant to its
Subsidiary Guarantee and the terms of the Indenture are subordinated in right of
payment to the prior payment in full in cash of all Senior Indebtedness of such
Subsidiary Guarantor to the extent set forth in the Indenture. Each Holder by
his acceptance hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on his behalf, to take such action as may be
necessary or appropriate to effectuate the subordination provided for in the
Indenture and appoints the Trustee his attorney-in-fact for such purposes.

            6. Redemption.

            (a) Optional Redemption. Except as set forth in the following
paragraph, the Notes shall not be redeemable at the option of the Company prior
to October 31, 2003. Thereafter, the Notes shall be redeemable, at the Company's
option, in whole or in part, at any time or from time to time, upon not less
than 30 nor more than 60 days' prior notice mailed by first-class mail to each
Holder's registered address, at the following redemption prices (expressed in
percentages of principal amount), plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date), if redeemed during
the 12-month period commencing on October 31 of the years set forth below:

                                                          Redemption
            Period                                          Price
            ------                                        ----------

            2003 .......................................   106.500%
            2004 .......................................   104.333%
            2005 .......................................   102.167%
            2006 and thereafter.........................   100.000%


                                       B-4
<PAGE>

            (b) Optional Redemption Upon Public Equity Offerings. In addition,
at any time and from time to time prior to October 31, 2001, the Company may
redeem in the aggregate up to 35% of the original principal amount of the Notes
with the Net Cash Proceeds of one or more Public Equity Offerings, at a
redemption price (expressed as a percentage of principal amount) of 113.000%
plus accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that at least 65% of the aggregate
principal amount of the Notes originally outstanding must remain outstanding
after each such redemption.

            In order to effect the foregoing redemption with the proceeds of any
Public Equity Offering, the Company shall make such redemption not more than 120
days after the consummation of any such Public Equity Offering.

            7. Notice of Redemption. Notice of redemption shall be mailed at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Notes to be redeemed at such Holder's registered address. Notes in
denominations of $1,000 may be redeemed only in whole. Notes in denominations
larger than $1,000 may be redeemed in part but only in multiples of $1,000.

            Except as set forth in the Indenture, if monies for the redemption
of the Notes called for redemption shall have been deposited with the Paying
Agent for redemption on such Redemption Date, then, unless the Company defaults
in the payment of such Redemption Price plus accrued and unpaid interest, if
any, the Notes called for redemption will cease to bear interest from and after
such Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued and unpaid interest, if
any.

            8. Offers to Purchase. Sections 4.16 and 4.17 of the Indenture
provide that, in the event of certain Asset Dispositions (as defined in the
Indenture) and upon the occurrence of a Change of Control (as defined in the
Indenture), and subject to further limitations contained therein, the Company
will make an offer to purchase certain amounts of the Notes in accordance with
the procedures set forth in the Indenture.

            9. Denominations; Transfer; Exchange. The Notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000. A Holder shall register the transfer of or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for redemption
(except, in the case of Notes to be redeemed in part, the portion of such Notes
not to be redeemed) or any Note for a period beginning 15 Business Days before
the mailing of a notice of an offer to repurchase or a notice of redemption or
15 Business Days before any Interest Payment Date.

            10. Persons Deemed Owners. The registered Holder of a Note shall be
treated


                                       B-5
<PAGE>

as the owner of it for all purposes.

            11. Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company (subject to any applicable abandoned property
law). After that, all liability of the Trustee and such Paying Agent with
respect to such money shall cease.

            12. Discharge Prior to Redemption or Maturity. If the Company at any
time deposits with the Trustee U.S. Legal Tender or U.S. Government Obligations
sufficient to pay the principal of and interest on the Notes to redemption or
maturity and complies with the other provisions of the Indenture relating
thereto, the Company will be discharged from certain provisions of the Indenture
and the Notes (including certain covenants, but excluding its obligation to pay
the principal of and interest on the Notes).

            13. Amendment; Supplement; Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the written
consent of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding, and any existing Default or Event of Default or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in aggregate principal amount of the Notes then
outstanding. Without notice to or consent of any Holder, the parties thereto may
amend or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, omission, defect or inconsistency, provide for uncertificated Notes
in addition to or in place of certificated Notes, or comply with Article Five of
the Indenture or make any other change that does not adversely affect in any
material respect the rights of any Holder of a Note.

            14. Restrictive Covenants. The Indenture imposes certain limitations
on the ability of the Company and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, make payments in respect of its Capital
Stock or certain Indebtedness, enter into transactions with Affiliates, create
dividend or other payment restrictions affecting Subsidiaries, merge or
consolidate with any other Person, sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets or adopt a plan of
liquidation. Such limitations are subject to a number of important
qualifications and exceptions. The Company must annually report to the Trustee
on compliance with such limitations.

            15. Successors. When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor will be released from those obligations.

            16. Defaults and Remedies. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Notes then outstanding may declare all the Notes to be due and payable
in the manner, at the time and with the effect provided in the Indenture.
Certain events of bankruptcy and insolvency are Events of Default which will
result in the Notes being due and payable immediately upon the occurrence of
such Events of Default. Holders of Notes may not enforce the Indenture or the
Notes except as


                                       B-6
<PAGE>

provided in the Indenture. The Trustee is not obligated to enforce the Indenture
or the Notes unless it has received indemnity reasonably satisfactory to it. The
Indenture permits, subject to certain limitations therein provided, Holders of a
majority in aggregate principal amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal or interest) if it determines that withholding
notice is in their interest.

            17. Trustee Dealings with Company. The Trustee under the Indenture,
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

            18. No Recourse Against Others. No past, present or future
stockholder, director, officer, employee or incorporator, as such, of the
Company or any Subsidiary Guarantor shall have any liability for any obligation
of the Company under the Notes or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation. Each Holder of a
Note by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Notes.

            19. Authentication. This Note shall not be valid until the Trustee
or Authenticating Agent manually signs the certificate of authentication on this
Note.

            20. Governing Law. The Laws of the State of New York shall govern
this Note and the Indenture (and the Subsidiary Guarantees relating thereto),
without regard to principles of conflict of laws.

            21. Abbreviations and Defined Terms. Customary abbreviations may be
used in the name of a Holder of a Note or an assignee, such as: TEN COM (=
tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint
tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

            22. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes as a convenience to the Holders of the
Notes. No representation is made as to the accuracy of such numbers as printed
on the Notes and reliance may be placed only on the other identification numbers
printed hereon.

            23. Indenture. Each Holder, by accepting a Note, agrees to be bound
by all of the terms and provisions of the Indenture, as the same may be amended
from time to time.

            24. [Registration Rights. Pursuant to the Registration Rights
Agreement (as defined in the Indenture), the Company will have certain
obligations to the Holders of the Private Exchange Notes.]

                               REGISTRATION RIGHTS

            SECTION 2.01. Rule 144A Matters, Initial Registration and Demand
Registration. (a) Immediately following the date hereof, the Issuer will as
promptly as practicable prepare an offering memorandum (as amended or
supplemented, the "Rule 144A Offering Memorandum") relating to the Senior
Subordinated Notes so that such Senior Subordinated


                                      -5-

<PAGE>

Notes may be resold by the CSFB Entity (and if so prepared for the CSFB Entity,
by the DLJ Entities or the Chase Entity if they elect to participate) (the
participating CSFB Entity, DLJ Entities and the Chase Entity are hereinafter
referred to as the "Rule 144A Sellers") pursuant to Rule 144A or Regulation S
under the Securities Act. Such Rule 144A Offering Memorandum shall contain such
disclosures as are customary and appropriate for such a document. In addition,
in connection with the preparation of such Rule 144A Offering Memorandum, the
Issuer shall (i) execute such customary and appropriate documents or agreements
relating to such Senior Subordinated Notes and their terms including providing
for customary opinions, comfort letters and indemnification provisions relating
to the Rule 144A Offering Memorandum, as determined by the Rule 144A Sellers and
reasonably agreed to by the Issuer, and (ii) enter into a registration rights
agreement in form and substance reasonably satisfactory to the Issuer and the
Rule 144A Sellers that provides for the exchange of Senior Subordinated Notes
for securities with substantially the same terms and conditions as the Senior
Subordinated Notes except for transfer restrictions (the "Exchange Offer
Registration Rights Agreement"). As used in this Section 2.01 (a), the term
"customary and appropriate" shall be determined with reference to Rule 144A
transactions underwritten by nationally recognized investment banking firms and
involving securities that are similar to the Senior Subordinated Notes and that
are issued by entities that are not subject to the reporting requirements of the
Exchange Act.

            The Issuer will promptly advise the Rule 144A Sellers of the
happening of any event that would require an amendment of or supplement to the
Rule 144A Offering Memorandum then being used so that the Rule 144A Offering
Memorandum as thereafter delivered to purchasers would not include any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein not misleading. Upon receipt of such notice, the Rule
144A Sellers shall cease delivering such Rule 144A Offering Memorandum to
prospective purchasers of the Senior Subordinated Notes until such time as such
amended or supplemented Rule 144A Offering Memorandum is available for delivery
to such prospective purchasers. The Issuer will also give the Rule 144A Sellers
notice of any intention to make any amendment or supplement to the Rule 144A
Offering Memorandum, will furnish the Rule 144A Sellers in advance with copies
of any such amendment or supplement proposed to be made and will not permit any
such amendment or supplement to be made without first consulting with the Rule
144A Sellers and their counsel.

            The Issuer will furnish to the Rule 144A Sellers copies of the Rule
144A Offering Memorandum and all amendments and supplements thereto, in each
case as soon as available and in such quantities as the Rule 144A Sellers may
reasonably request.

            Unless otherwise agreed to by all of the parties hereto, the right
of the Rule 144A Sellers to resell Senior Subordinated Notes pursuant to this
Section 2.01(a) (other than pursuant to the Exchange Offer Registration Rights
Agreement) shall expire upon the earlier of (x) the sale of all of the Senior
Subordinated Notes pursuant to the Rule 144A Offering Memorandum or (y) the
Business Day immediately prior to the earlier of (A) the filing of the Initial
Registration and (B) the filing of the Exchange Offer Registration Statement.

            The Exchange Offer Registration Rights Agreement shall provide,
among other things, that the Issuer shall, if Senior Subordinated Notes have
been sold under the Rule 144A 


                                      -6-

<PAGE>

Offering Memorandum, at its own cost, use its reasonable best efforts to prepare
and, not later than 60 days after (or if the 60th day is not a Business Day, the
first Business Day thereafter) the date hereof, file with the SEC a registration
statement ("Exchange Offer Registration Statement") on an appropriate form under
the Securities Act, with respect to a proposed offer (the "Registered Exchange
Offer") to the holders of Senior Subordinated Notes sold under the Rule 144A
Offering Memorandum, who are not prohibited by any law or policy of the SEC from
participating in the Registered Exchange Offer, to issue and deliver to such
holders, in exchange for such Senior Subordinated Notes, a like aggregate
principal amount of debt securities of the Issuer issued under the indenture
relating to the Senior Subordinated Notes (the "Exchange Securities") and
identical in all material respects to the Senior Subordinated Notes (except for
the transfer restrictions relating to the initial Senior Subordinated Notes)
that would be registered under the Securities Act. The Issuer shall use its
reasonable best efforts to cause such Exchange Offer Registration Statement to
become effective under the Securities Act within 150 days (or if the 150th day
is not a Business Day, the first Business Day thereafter) from the date hereof
and shall keep the Exchange Offer Registration Statement effective for not less
than 30 days (or longer, if required by applicable law) after the date notice of
the Registered Exchange Offer is mailed to the holders.

            Prior to the filing of the Exchange Offer Registration Statement and
the registration statement related to the Initial Registration, the parties
hereto shall use their reasonable best efforts to take such actions as are
necessary such that the Exchange Securities and the Securities (the "Initial
Securities") held by the CSFB Entity, the DLJ Entities and the Chase Entity (the
"Original Holders") after being registered pursuant to the Initial Registration
(as defined below) are traded as fungible securities, including, if appropriate,
legal and in compliance with the Securities Act, having the Issuer,
simultaneously with the delivery of the Exchange Securities pursuant to the
Registered Exchange Offer, issue and deliver to such Original Holders upon the
written request of such Original Holders, in exchange for the Initial Securities
held by such Original Holders, a like principal amount of debt securities (the
"Private Exchange Securities") of the Issuer issued under the indenture relating
to the Senior Subordinated Notes and identical in all material respects (other
than the inclusion of provisions relating to restrictions on transfer under the
Securities Act and the securities laws of the several states of the United
States identical to such provisions in the Initial Securities), to the Exchange
Securities.

            (b) In addition to the Issuer's obligations under Section 2.01(a),
the Issuer will (i) file a registration statement under the Securities Act
relating to all of the Registrable Securities held by the Securityholders (the
"Initial Registration") within 60 days from the date hereof (or if the 60th day
is not a Business Day, the first Business Day thereafter), and (ii) use its
reasonable best efforts to have such registration statement declared effective
within 150 days from the date hereof (or if the 150th day is not a Business Day,
the first Business Day thereafter), all to the extent necessary to permit the
disposition (in accordance with the intended methods thereof) of the Registrable
Securities. Securityholders representing a majority of the outstanding principal
amount of the Registrable Securities may, at any time prior to the effective
date of the registration statement relating to such registration, revoke such
request, without liability to any of the other Securityholders, by providing a
written notice to ESPH revoking such request.


                                      -7-

<PAGE>

            (c) In the event that all of the Senior Subordinated Notes have not
been sold under the Rule 144A Offering Memorandum pursuant to Section 2.01 (a)
or under the Initial Registration pursuant to Section 2.01(b), subject to the
provisions herein, from and after the date which is twelve months after the date
effectiveness of any registration statement pursuant to Section 2.01(b) expires,
any DLJ Entity, the CSFIB Entity or the Chase Entity that holds Registrable
Securities may make a written request (any such requesting Person, a "Selling
Securityholder") that the Issuer effect the registration under the Securities
Act of all or a portion of such Selling Securityholder's Registrable Securities,
which request shall specify the intended method of disposition thereof. All such
written requests will be sent to ESPH and each potential Selling Securityholder
and more than one Selling Securityholder may request a Demand Registration (as
defined below) at the same time. The Issuer will promptly give written notice of
such requested registration (a "Demand Registration") at least 30 days prior to
the anticipated filing date of the registration statement relating to such
Demand Registration to all other Securityholders and thereupon will use its best
efforts to effect, as expeditiously as possible, the registration under the
Securities Act of the Registrable Securities which the Issuer has been so
requested to register by the Selling Securityholders and the Registrable
Securities which the other Securityholders have requested the Issuer to register
by written request received by ESPH within 15 days after the receipt by such
Securityholders of such written notice given by the Issuer (all such
Securityholders, together with the Selling Securityholders, the "Holders"), all
to the extent necessary to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered; provided that, subject to Section 2.01(e) hereof, the Issuer shall
not be obligated to effect more than one Demand Registration pursuant to this
Section 2.01. Promptly after the expiration of the 15-day period referred to
above, the Issuer will notify all the Holders to be included in the Demand
Registration of the other Holders and the number of shares of Registrable
Securities requested to be included therein. The Selling Securityholders
requesting a registration under this Section 2.01 may, at any time prior to the
effective date of the registration statement relating to such registration,
revoke such request, without liability to any of the other Holders, by providing
a written notice to ESPH revoking such request, in which case such request, so
revoked, shall be not considered a Demand Registration; provided that all
Registration Expenses relating to such revoked registration are reimbursed by
such Selling Securityholders (unless such revocation arose out of the fault of
the Issuer, in which case no such reimbursement need be made).

            (d) The Issuer will pay all Registration Expenses in connection with
any registration pursuant to this Section 2.01.

            (e) The Initial Registration or a Demand Registration pursuant to
this Section 2.01 shall not be deemed to have been effected unless the
registration statement relating thereto (i) has become effective under the
Securities Act and (ii) has remained effective for a period of, in the case of
the Initial Registration, at least 180 days (or such shorter period in which all
Registrable Securities included in such registration have actually been sold
thereunder) and, in the case of a Demand Registration, at least 90 days (or such
shorter period in which all Registrable Securities included in such registration
have actually been sold thereunder); provided that, if after any such
registration statement becomes effective such registration statement is
interfered with by any stop order, injunction or other order or requirement of
the SEC or other governmental agency or court, such registration statement shall
be at the sole expense of the Issuer and shall not be 


                                       -8-

<PAGE>

considered the Initial Registration or a Demand Registration, unless any such
interference referred to in this proviso arose out of the fault of the Holders
of the Registrable Securities included in such registration statement, in which
case such registration statement shall be considered the Initial Registration or
a Demand Registration, as the case may be.

            SECTION 2.02. Registration Procedures. Pursuant to Section 2.01(b)
and whenever Securityholders request that any Registrable Securities be
registered pursuant to Section 2.01(c), the Issuer will, subject to the
provisions of such Sections, use its best efforts to effect the registration and
the sale of such Registrable Securities in accordance with the intended method
of disposition thereof as quickly as practicable, and in connection with any
such request:

            (a) The Issuer will as expeditiously as possible (in the case of the
      Initial Registration, within 60 days from the date hereof) prepare and
      file with the SEC a registration statement on any form for which the
      Issuer then qualifies or which counsel for the Issuer shall deem
      appropriate and which form shall be available for the sale of the
      Registrable Securities to be registered thereunder in accordance with the
      intended method of distribution thereof, and use its best efforts (in the
      case of the Initial Registration, within 150 days from the date hereof) to
      cause such filed registration statement to become effective and to remain
      effective for a period of, in the case of the Initial Registration, not
      less than 180 days (or such shorter period in which all of the Registrable
      Securities of the Securityholders included in such registration statement
      shall have actually been sold thereunder) and, in the case of a Demand
      Registration, not less than 90 days (or such shorter period in which all
      of the Registrable Securities of the Securityholders included in such
      registration statement shall have actually been sold thereunder).

            (b) The Issuer will, if requested, prior to filing a registration
      statement or prospectus or any amendment or supplement thereto, furnish to
      each Securityholder and each underwriter, if any, of the Registrable
      Securities covered by such registration statement copies of such
      registration statement as proposed to be filed, and thereafter the Issuer
      will furnish to such Securityholder and underwriter, if any, such number
      of copies of such registration statement, each amendment and supplement
      thereto (in each case including all exhibits thereto and documents
      incorporated by reference therein), the prospectus included in such
      registration statement (including each preliminary prospectus) and such
      other documents as such Securityholder or underwriter may reasonably
      request in order to facilitate the disposition of the Registrable
      Securities owned by such Securityholder. Each Securityholder shall have
      the right to request that the Issuer modify any information contained in
      such registration statement, amendment and supplement thereto pertaining
      to such Securityholder and the Issuer shall use its reasonable best
      efforts to comply with such request, provided that the Issuer shall not
      have any obligation to so modify any information if so doing would cause
      the prospectus to contain an untrue statement of a material fact or omit
      to state any material fact required to be stated therein or necessary to
      make the statements therein not misleading.

            (c) After the filing of the registration statement, the Issuer will
      cause the related prospectus to be supplemented by any required prospectus
      supplement, and as so supplemented to be filed pursuant to Rule 424 under
      the Securities Act, (ii) comply with 


                                      -9-

<PAGE>

      the provisions of the Securities Act with respect to the disposition of
      all Registrable Securities covered by such registration statement during
      the applicable period in accordance with the intended methods of
      disposition by the sellers thereof set forth in such registration
      statement or supplement to such prospectus and promptly notify each
      Securityholder holding Registrable Securities covered by such registration
      statement of any stop order issued or threatened by the SEC and take all
      reasonable actions required to prevent the entry of such stop order or to
      remove it if entered.

            (d) The Issuer will use its best efforts to (i) register or qualify
      the Registrable Securities covered by such registration statement under
      such other securities or blue sky laws of such jurisdictions in the United
      States as any Securityholder holding such Registrable Securities
      reasonably (in light of such Securityholder's intended plan of
      distribution) requests and (ii) cause such Registrable Securities 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 Issuer and do any and all other acts and things that may be
      reasonably necessary or advisable to enable such Securityholder to
      consummate the disposition of the Registrable Securities owned by such
      Securityholder; provided that the Issuer will not be required to (A)
      qualify generally to do business in any jurisdiction where it would not
      otherwise be required to qualify but for this paragraph (d), (B) subject
      itself to taxation in any such jurisdiction or (C) consent to general
      service of process in any such jurisdiction.

            (e) The Issuer will immediately notify each Securityholder holding
      such Registrable Securities covered by such registration statement, at any
      time when a prospectus relating thereto is required to be delivered under
      the Securities Act, of the occurrence of an event requiring the
      preparation of a supplement or amendment to such prospectus so that, as
      thereafter delivered to the purchasers of such Registrable Securities,
      such prospectus will not contain an untrue statement of a material fact or
      omit to state any material fact required to be stated therein or necessary
      to make the statements therein not misleading and promptly prepare and
      make available to each such Securityholder and file with the SEC any such
      supplement or amendment.

            (f) Except as provided below, the Issuer may select the underwriter
      or underwriters in connection with the Initial Registration and any Demand
      Registration as it may deem appropriate. If the Initial Registration is an
      Underwritten Public Offering, the DLJ Entities will have the right to
      select one co-lead managing underwriter and, if the CSFB Entity has
      Registrable Securities covered by such registration, the CSFB Entity will
      have the right to select the other co-lead managing underwriter provided
      that if the CSFB Entity has no Registrable Securities covered by such
      registration, the DLJ Entities will have the right to select the lead
      managing underwriter. If any Demand Registration is an Underwritten Public
      Offering, the DLJ Entities and, if the CSFB Entity has Registrable
      Securities covered by such registration, the CSFB Entity will each have
      the right to select one of the co-lead managing underwriters; provided
      that such Entities or Entity, as the case may be, have Registrable
      Securities covered by such registration. Any Affiliate of any of the DLJ
      Entities or any affiliate of the CSFB Entities may be selected as
      underwriter for the Initial Registration and any Demand Registration. The
      Issuer will 


                                      -10-

<PAGE>

      enter into customary agreements (including an underwriting agreement in
      customary form) and take such other actions as are reasonably required in
      order to expedite or facilitate the disposition of such Registrable
      Securities, including the engagement of a "qualified independent
      underwriter" in connection with the qualification of the underwriting
      arrangements with the NASD. If any DLJ Entity elects to be a Rule 144A
      Seller, the DLJ Entities will have the right to select one co-lead
      managing underwriter or placement agent and the CSFB Entity will have the
      right to select the other co-lead managing underwriter or placement agent
      in connection with sales under the Rule 144A Offering Memorandum.

            (g) The Issuer will make available for inspection by any
      Securityholder and any underwriter participating in any disposition
      pursuant to a registration statement being filed by the Issuer pursuant to
      this Section 2.02 and any attorney, accountant or other professional
      retained by any such Securityholder or underwriter (collectively, the
      "Inspectors"), all financial and other records, pertinent corporate
      documents and properties of the Issuer (collectively, the "Records") as
      shall be reasonably requested by any such Person, and cause the Issuer's
      officers, directors and employees to supply all information reasonably
      requested by any Inspectors in connection with such registration
      statement.

            (h) The Issuer will furnish to each such Securityholder and to each
      such underwriter, if any, a signed counterpart, addressed to such
      underwriter, of (i) an opinion or opinions of counsel to the Issuer and
      (ii) a comfort letter or comfort letters from the Issuer's independent
      public accountants, each in customary form and covering such matters of
      the type customarily covered by opinions or comfort letters, as the case
      may be, as a majority of such Securityholders or the managing underwriter
      therefor reasonably requests.

            (i) The Issuer will otherwise use its best efforts to comply with
      all applicable rules and regulations of the SEC, and make available to its
      securityholders, as soon as reasonably practicable, an earnings statement
      covering a period of 12 months, beginning within three months after the
      effective date of the registration statement, which earnings statement
      shall satisfy the provisions of Section 11(a) of the Securities Act.

            (j) The Issuer may require each such Securityholder to promptly
      furnish in writing to the Issuer such information regarding the
      distribution of the Registrable Securities as the Issuer may from time to
      time reasonably request and such other information as may be legally
      required in connection with such registration.

            (k) Each such Securityholder agrees that, upon receipt of any notice
      from the Issuer of the happening of any event of the kind described in
      Section 2.02(e) hereof, such Securityholder will forthwith discontinue
      disposition of Registrable Securities pursuant to the registration
      statement covering such Registrable Securities until such Securityholder's
      receipt of the copies of the supplemented or amended prospectus
      contemplated by Section 2.02(e) hereof, and, if so directed by the Issuer,
      such Securityholder will deliver to the Issuer all copies, other than any
      permanent file copies then in such Securityholder's possession, of the
      most recent prospectus covering such Registrable Securities at the time 


                                      -11-

<PAGE>

      of receipt of such notice. In the event that the Issuer shall give such
      notice, the Issuer shall extend the period during which such registration
      statement shall be maintained effective (including the period referred to
      in Section 2.02(a) hereof) by the number of days during the period from
      and including the date of the giving of notice pursuant to Section 2.02(e)
      hereof to the date when the Issuer shall make available to such
      Securityholder a prospectus supplemented or amended to conform with the
      requirements of Section 2.02(e) hereof.

            SECTION 2.03. Indemnification by the Issuer. The Issuer agrees to
indemnify and hold harmless each Securityholder holding Registrable Securities
covered by a registration statement, its officers, directors and agents, and
each Person, if any, who controls such Securityholder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities caused by any untrue
statement or alleged untrue statement of a material fact contained in any
registration statement or prospectus relating to the Registrable Securities (as
amended or supplemented if the Issuer shall have furnished any amendments or
supplements thereto) or any preliminary prospectus, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission so made in strict
conformity with information furnished in writing to the Issuer by such
Securityholder or on such Securityholder's behalf expressly for use therein;
provided that with respect to any untrue statement or omission or alleged untrue
statement or omission made in any preliminary prospectus, or in any prospectus,
as the case may be, the indemnity agreement contained in this paragraph shall
not apply to the extent that any such loss, claim, damage, liability or expense
results from the fact that a current copy of the prospectus (or, in the case of
a prospectus, the prospectus as amended or supplemented) was not sent or given
to the Person asserting any such loss, claim, damage, liability or expense at or
prior to the written confirmation of the sale of the Registrable Securities
concerned to such Person if it is determined that the Issuer has provided such
prospectus and it was the responsibility of such Securityholder to provide such
Person with a current copy of the final prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the final
prospectus (or such amended or supplemented prospectus, as the case may be)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. The Issuer also agrees to indemnify any underwriters of the
Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Securityholders provided in this Section 2.03.

            SECTION 2.04. Indemnification by Participating Securityholders. (a)
Subject to Section 2.04(b), each Securityholder holding Registrable Securities
included in any registration statement agrees, severally but not jointly, to
indemnify and hold harmless the Issuer, its officers, directors and agents and
each Person, if any, who controls the Issuer within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act to the same
extent as the foregoing indemnity from the Issuer to such Securityholder, but
only (i) with respect to information furnished in writing by such Securityholder
or on such Securityholder's behalf expressly for use in any registration
statement or prospectus relating to the Registrable Securities, or any amendment
or supplement thereto, or any preliminary prospectus or (ii) to the extent that


                                      -12-

<PAGE>

any loss, claim, damage, liability or expense described in Section 2.03 results
from the fact that a current copy of the prospectus (or, in the case of a
prospectus, the prospectus as amended or supplemented) was not sent or given to
the Person asserting any such loss, claim, damage, liability or expense at or
prior to the written confirmation of the sale of the Registrable Securities
concerned to such Person if it is determined that it was the responsibility of
such Securityholder to provide such Person with a current copy of the prospectus
(or such amended or supplemented prospectus, as the case may be) and such
current copy of the prospectus (or such amended or supplemented prospectus, as
the case may be) would have cured the defect giving rise to such loss, claim,
damage, liability or expense. Subject to Section 2.04(b), each such
Securityholder also agrees to indemnify and hold harmless underwriters of the
Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Issuer provided in this Section 2.04. As a condition to
including Registrable Securities in any registration statement filed in
accordance with Article 2 hereof, the Issuer may require that it shall have
received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities.

            (b) No Securityholder shall be liable under Section 2.04(a) for any
damage thereunder in excess of the net proceeds realized by such Securityholder
in the sale of the Registrable Securities of such Securityholder.

            SECTION 2.05. Conduct of Indemnification Proceedings. In case any
proceeding (including any governmental investigation) shall be instituted
involving any Person in respect of which indemnity may be sought pursuant to
this Article 2, such Person (an "Indemnified Party") shall promptly notify the
Person against whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Party, and
shall assume the payment of all fees and expenses; provided that the failure of
any Indemnified Party so to notify the Indemnifying Party shall not relieve the
Indemnifying Party of its obligations hereunder except to the extent that the
Indemnifying Party is materially prejudiced by such failure to notify. In any
such proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) in the
reasonable judgment of such Indemnified Party representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by the Indemnified
Parties. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any and all losses, claims, damages, liabilities and expenses or
liability (to the extent stated above) by reason of such settlement or judgment.
No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any 


                                      -13-

<PAGE>

settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability arising out
of such proceeding.

            SECTION 2.06. Contribution. If the indemnification provided for in
this Article 2 is held by a court of competent jurisdiction to be unavailable to
the Indemnified Parties in respect of any losses, claims, damages or liabilities
referred to herein, then each such Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities (i)
as between the Issuer and the Securityholders holding Registrable Securities
covered by a registration statement on the one hand and the underwriters on the
other, in such proportion as is appropriate to reflect the relative benefits
received by the Issuer and such Securityholders on the one hand and the
underwriters on the other, from the offering of the Registrable Securities, or
if such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Issuer and such Securityholders on the one hand and of such
underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations and (ii) as between the Issuer on the one hand
and each such Securityholder on the other, in such proportion as is appropriate
to reflect the relative fault of the Issuer and of each such Securityholder in
connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Issuer and such
Securityholders on the one hand and such underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the offering (net
of underwriting discounts and commissions but before deducting expenses)
received by the Issuer and such Securityholders bear to the total underwriting
discounts and commissions received by such underwriters, in each case as set
forth in the table on the cover page of the prospectus. The relative fault of
the Issuer and such Securityholders on the one hand and of such underwriters on
the other 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 Issuer
and such Securityholders or by such underwriters. The relative fault of the
Issuer on the one hand and of each such Securityholder on the other 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 such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

            The Issuer and the Securityholders agree that it would not be just
and equitable if contribution pursuant to this Section 2.06 were determined by
pro rata allocation (even if the underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable to an Indemnified Party as a result of the
losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 2.06, no underwriter shall be


                                      -14-

<PAGE>

required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no Securityholder
shall be required to contribute any amount in excess of the amount by which the
net proceeds realized on the sale of the Registrable Securities of such
Securityholder exceeds the amount of any damages which such Securityholder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. Each Securityholder's obligation to contribute
pursuant to this Section 2.06 is several in the proportion that the proceeds of
the offering received by such Securityholder bears to the total proceeds of the
offering received by all such Securityholders and not joint.

            SECTION 2.07. Participation in Public Offering. (a) No Person may
participate in the Initial Registration or any Demand Registration hereunder
unless such Person (i) agrees to sell such Person's securities on the basis
provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements and the provisions of this Agreement in respect of registration
rights.

            (b) In the event any Securityholder shall transfer any Registrable
Securities pursuant to Rule 144A under the Securities Act, the Issuer shall
cooperate with such Securityholder and shall use its reasonable best efforts to
provide to such Securityholder such information as such Securityholder shall
reasonably request.

                                    ARTICLE 3

                                  MISCELLANEOUS

            SECTION 3.01. Entire Agreement. The Transaction Documents constitute

liabilities under or by reason of this Agreement.

            SECTION 3.03. Assignability. Neither this Agreement nor any right,
remedy, obligation or liability arising hereunder or by reason hereof shall be
assignable by the Issuer or any Securityholder, except by any Securityholder to
its Permitted Transferees. Any Securityholder who ceases to beneficially own any
Securities shall cease to be bound by the terms hereof (other than Sections
2.04, 2.05 and 2.06).

            SECTION 3.04. Amendment; Waiver. No provision of this Agreement may
be waived except by an instrument in writing executed by the party against whom

instrument in writing executed by ESPH shall constitute an instrument in writing
executed by the Guarantors. No provision of this Agreement may be amended or
otherwise modified except by an instrument in writing executed by the parties
hereto; provided that for purposes of any such amendment or modification, an
instrument in writing executed by ESPH shall constitute an instrument in writing

Credit Suisse First Boston Corporation
    Eleven Madison Avenue
    New York, N.Y. 10010-3629

Dear Sirs:

      1. Introductory. Environmental Systems Products Holdings Inc., a Delaware
corporation (the "Company"), proposes to issue and sell $100,000,000 aggregate
principal amount of the Company's 13% Senior Subordinated Notes due 2008 (the
"Notes") and EnviroSystems Corp., a Delaware corporation and the sole
shareholder of the Company (the "Parent"), proposes to issue and sell 2,291.268
shares (the "Series A Shares") of Series A common stock, par value $0.0001 per
share (the "Series A Common Stock"), of the Parent. The Notes are to be issued
under an indenture, dated as of October 16, 1998 (the "Indenture"), among the
Company, the Parent, the Guarantors (as defined) and United States Trust Company
of New York, as Trustee (the "Trustee"), which Notes will be unconditionally
guaranteed by the guarantors listed on Schedule A hereto (collectively, the
"Guarantors," and together with the Company and the Parent, the "Issuers"). For
purposes of this agreement, (i) the term "Securities" means the Notes, together
with 

<PAGE>

the guarantees (the "Guarantees") thereof by the Guarantors, and the Series A
Shares and (ii) references to "Subsidiaries" or "subsidiaries" of the Company
shall mean all subsidiaries of the Company, including Envirotest Systems Corp.,
a Delaware corporation ("Envirotest"), and the direct and indirect subsidiaries
of Envirotest, and Environmental Systems Products, Inc., a Delaware corporation
("ESP"), and the direct and indirect subsidiaries of ESP. The United States
Securities Act of 1933, as amended, is herein referred to as the "Securities
Act."

      Pursuant to the terms of an Agreement and Plan of Merger, dated as of
August 12, 1998 (the "Merger Agreement"), among ESP, Stone Rivet, Inc., a
Delaware corporation ("Stone Rivet") and a wholly-owned subsidiary of ESP, and
Envirotest, Stone Rivet made a cash tender offer (the "Equity Offer") to acquire
all of the issued and outstanding shares of Envirotest's Class A Common Stock,
par value $.01 per share, under an Offer to Purchase, dated August 19, 1998 (the
"Equity Offer to Purchase"). Pursuant to the Merger Agreement, (i) upon
completion of the Equity Offer, Stone Rivet will be merged with and into
Envirotest, (ii) the separate corporate existence of Stone Rivet will cease and
(iii) Envirotest will continue as the surviving corporation (the above
transactions are herein referred to as the "Merger"). The net proceeds of the
sale of the Notes and the Series A Shares, together with the net proceeds from
the sale by the Parent of 15% Senior Discount Notes due 2009 and shares of
Series A Common Stock in connection therewith (the "Senior Discount
Transaction"), a portion of the initial borrowings under the New Credit Facility
(as defined below), available cash and the proceeds of the Equity Investment (as
defined below), will be used to finance the Merger and to complete the
Refinancing Plan (as defined below). Concurrently with the consummation of the
issuance and sale of the Notes and the Series A Shares hereunder, Alchemy
Partners (Guernsey) Limited, a U.K. partnership, shall cause to be made by
certain shareholders of Newmall Ltd., a company incorporated under the laws of
England and Wales, an indirect equity contribution of approximately $80 million
to ESP (the "Equity Contribution"). Immediately prior to the issuance and sale
of the Notes and the Series A Shares, the shareholders of Newmall shall exchange
their Newmall shares for shares of stock in the Company (the "Newmall Share
Exchange"). In addition, the shareholders of the Company shall exchange their
shares of the Company for shares of the Parent (the "Company Share Exchange"
and, collectively with the Newmall Share Exchange, the "Share Exchange"). In
addition, the Parent and the purchasers party thereto shall enter into a share
price adjustment agreement, dated October 16, 1998 (the "Share Price Adjustment
Agreement"), regarding the shares of Series A Common Stock to be issued in
connection with this Agreement and the Senior Discount Transaction (the "Share
Price Adjustment"). At or prior to the issuance and sale of the Notes and the
Series A Shares, the Parent, the Company and certain of its subsidiaries intend
to 


                                       2

<PAGE>

complete a refinancing plan (the "Refinancing Plan"). The principal elements of
the Refinancing Plan are: (i) the issuance and sale of the Notes and the Series
A Shares; (ii) the Senior Discount Transaction; (iii) the offers by the Company
to purchase, and the solicitation of consents (together, the "Debt Offers") from
the holders of, all of the outstanding 9 1/8% Senior Notes due 2001 (the "2001
Notes") and 9 5/8% Senior Subordinated Notes due 2003 (the "2003 Notes" and,
together with the 2001 Notes, the "Existing Notes") of Envirotest pursuant to
Offers to Purchase and Consent Solicitations, each dated September 1, 1998 (the
"Debt Offers to Purchase"); (iv) the entering by the Company into a new senior
secured credit facility consisting of up to approximately an aggregate of $385
million of term loan facilities and up to approximately an aggregate of $50
million of revolving credit facilities (the "New Credit Facility") with Credit
Suisse First Boston Corporation ("CSFB"), as administrative and collateral
agent, DLJ Capital Funding, Inc. ("DLJCF"), as syndication agent, and certain
lenders named therein; (v) the repayment in full of indebtedness under ESP's
existing credit facility (the "ESP Credit Facility") and the termination of such
facility; (vi) the repayment in full of approximately $___ million of other
outstanding indebtedness of Envirotest; (vii) the Equity Contribution; and
(viii) certain other refinancing transactions (together with the transaction
described in (vi) above, the "Other Refinancings"). After the Closing Date, upon
consummation of the Merger, pursuant to a Stock Purchase Agreement, dated
______, 1998 (the "Envirotest Agreement"), between ESP and the Company, all of
the outstanding capital stock of Envirotest will be sold to the Company by ESP
(the "Envirotest Sale") in exchange for a subordinated note of the Company in
the amount of $[80.0] million to be issued to ESP. Upon consummation of the
Envirotest Sale, Envirotest will become a wholly-owned direct subsidiary of the
Company. In addition, the Company expect that after the Closing Date (as
hereinafter defined), it and/or one of its subsidiaries will enter into a
written agreement, (the "Transervice Agreement"), with Wellman Overseas Ltd., an
affiliate of the Company ("Wellman"), to acquire the Transervice division of
Wellman (the "Transervice Acquisition") for aggregate consideration of
approximately $13.5 million.

dated October 15, 1998 (the "Subscription Agreement"), among the Issuers and the
purchasers named therein substantially in the form of Exhibit B hereto, the
Registration Rights Agreement, dated October 16, 1998 (the "Registration Rights

      the Securities to be sold to the purchasers thereof has been prepared by
      the Company and the Parent. Such Offering Memorandum shall be referred to
      herein as the "Offering Document." On the date of this Agreement and as of
      the Closing Date, the Offering Document does not and will not include any

      otherwise), properties or results of operations of the Parent, the Company
      and its subsidiaries, taken as a whole (a "Material Adverse Effect").

           (c)  Each subsidiary of the Company was duly incorporated and is in

      Securities Act in the offering and sale contemplated by this Agreement and
      the Subscription Agreement.

      payment in connection with the Transactions.

           (m)  Except as disclosed in the Offering Document, there are no

      or modification of any such certificate, authority or permit that, if
      determined adversely to the Parent, the Company or any of its
      subsidiaries, would individually or in the aggregate, have a Material
      Adverse Effect.

      slowdown, stoppage or dispute (except for routine disciplinary and
      grievance matters) with the employees of the Parent, the Company or any of

           (w)  Except as disclosed in the Offering Document, there are no
      pending actions, suits or proceedings against or affecting the Parent, the
      Company, any of their subsidiaries or any of their respective properties
      that, if determined adversely to the Parent, the Company or any of its

      Adverse Effect or would materially and adversely affect the ability of the
      Parent, the Company and their subsidiaries to perform their respective
      obligations under the Transaction Documents, or which are otherwise
      material in the context of the sale of the Securities and the consummation
      of the other Transactions; and, to the Parent's, the Company's and their

           (x)  The historical financial statements of each of ESP and

<PAGE>

      Offering Document present fairly the financial position of each of ESP and
      Envirotest and their respective consolidated subsidiaries as of the dates
      shown and their results of operations and cash flows for the periods
      shown, and such financial statements have been prepared in conformity with
      the generally accepted accounting principles in the United States applied
      on a consistent basis. The assumptions used in preparing the pro forma
      financial statements included in the Offering Document provide a
      reasonable basis for presenting the significant effects directly
      attributable to the transactions or events described therein, the related
      pro forma adjustments give appropriate effect to those assumptions, and
      the pro forma columns therein reflect the proper application of those
      adjustments to the corresponding historical financial statement amounts.
      The pro forma financial statements of the Company and the Parent, together
      with related schedules and notes, set forth in the Offering Document
      comply in all material respects with the requirements applicable to pro
      forma financial statements to be included in a registration statement on
      Form S-1 under the Securities Act.

           (y)  Except as disclosed in the Offering Document, since the date of
      the latest financial statements included in the Offering Document, there
      has been no material adverse change in the business, condition (financial
      or other), properties or results of operations of the Company and its
      subsidiaries taken as a whole (a "Material Adverse Change"), nor any
      development or event involving a prospective Material Adverse Change and,
      except as disclosed in or contemplated by the Offering Document, there has
      been no dividend or distribution of any kind declared, paid or made by the
      Parent or the Company on any class of its capital stock.

           (z)  The proceeds to the Issuers from the issuance and sale of the
      Securities will not be used to purchase or carry any security except any
      securities evidencing indebtedness being purchased in connection with the
      Refinancing Plan. None of the Issuers is an open-end investment company,
      unit investment trust or face-amount certificate company that is or is
      required to be registered under Section 8 of the United States Investment
      Company Act of 1940 (the "Investment Company Act"); and each of the
      Issuers is not and, after giving effect to the offering and sale of the
      Securities and the application of the proceeds thereof as described in the
      Offering Document and the consummation of the other Transactions, will not
      be, an "investment company" as defined in the Investment Company Act.

           (aa)  Each of the Parent, the Company and their subsidiaries is, and


                                       11

<PAGE>

      immediately after the Closing Date will be, Solvent. As used herein, the
      term "Solvent" means, with respect to each of the Parent, the Company and
      its subsidiaries on a particular date, that on such date (A) the fair
      market value of the assets of the Company or such subsidiary is greater
      than the total amount of liabilities (including contingent liabilities) of
      the Parent, the Company or such subsidiary, (B) the present fair salable
      value of the assets of the Parent, the Company or such subsidiary is
      greater than the amount that will be required to pay the probable
      liabilities of the Parent, the Company or such subsidiary on its debts as
      they become absolute and matured, (C) the Parent, the Company or such
      subsidiary is able to realize upon its assets and pay its debts and other
      liabilities, including contingent obligations, as they mature, and (D) the
      Parent, the Company or such subsidiary does not have unreasonably small
      capital.

           (bb)  No securities of the Parent, the Company or any of its
      subsidiaries of the same class (within the meaning of Rule 144A(d)(3)
      under the Securities Act) as the Securities are listed on any national
      securities exchange registered under Section 6 of Exchange Act or quoted
      in a U.S. automated inter-dealer quotation system.

           (cc)  The issuance and sale of the Securities in the manner
      contemplated by this Agreement and the Subscription Agreement will be
      exempt from the registration requirements of the Securities Act by reason
      of Section 4(2) thereof and Regulation S thereunder; and it is not
      necessary to qualify an indenture in respect of the Notes under the United
      States Trust Indenture Act of 1939, as amended (the "Trust Indenture
      Act").

           (dd)  None of the Parent, the Company, or any of their affiliates,
      nor any person acting on its or their behalf (i) has, within the six-month
      period prior to the date hereof, offered or sold in the United States or
      to any U.S. person (as such terms are defined in Regulation S under the
      Securities Act) the Securities or any security of the same class or series
      as the Securities or (ii) has offered or will offer or sell the Securities
      (A) in the United States by means of any form of general solicitation or
      general advertising within the meaning of Rule 502(c) under the Securities
      Act or (B) with respect to any such securities sold in reliance on Rule
      903 of Regulation S under the Securities Act, by means of any directed
      selling efforts within the meaning of Rule 902(b) of Regulation S. The
      Parent, the Company and any person acting on their behalf have complied
      and will comply with the offering restrictions requirement of Regulation
      S. Neither the Parent nor the Company has entered 


                                       12

<PAGE>

      and they will not enter into any contractual arrangement with respect to
      the issuance and sale of the Securities except for this Agreement, the
      Registration Rights Agreement, the Investors Agreement and the
      Subscription Agreement.

           (ee)  Neither the Parent nor the Company has, directly or indirectly,
      solicited any offer to buy or offered to sell, and they will not, directly
      or indirectly, solicit any offer to buy or offer to sell, in the United
      States or to any United States citizen or resident, any security that is
      or would be integrated with the sale of the Securities in a manner that
      would require the Securities to be registered under the 1933 Act.

           (ff)  The issuance and sale of the Securities hereunder will not
      involve any transaction that is subject to the prohibitions of Section
      406(a)(1) of the Employee Retirement Income Security Act of 1974, as
      amended ("ERISA") or in connection with which a tax could be imposed
      pursuant to Section 4975(c)(1)(A)-(D) of the Internal Revenue Code of
      1986, as amended (the "Code"). The representation of the Issuers in the
      first sentence of this Article 2(ff) is made in reliance upon, and subject
      to the accuracy of, the representations of the Purchasers in Article 4.2
      of the Subscription Agreement, and with respect to any transferee, the
      accuracy of the representation made by such transferee pursuant to Article
      4.3(b) of the Subscription Agreement.

            No condition exists or event or transaction has occurred in
      connection with any Benefit Plan maintained or contributed to by the
      Company and its subsidiaries, or any Affiliate of any such entity, which
      is likely to result in any of them incurring any liability, fine or
      penalty which singly or in the aggregate would have a material adverse
      effect on the Company and its subsidiaries, taken as a whole, resulting
      from the failure of the Company or its subsidiaries or any Affiliate of
      any such entity to comply with ERISA insofar as such Act applies to them.

           (gg)  The Company is an "operating company" as such term is defined
      in Department of Labor Regulation 2510.3-101(c), as may be amended.

Agreement. The Placement Agent shall have the right, in its sole discretion, to
reject any offer received by it to purchase Notes and Series A Shares, as a
whole or in part, and any such rejection by the Placement Agent shall not be
deemed a breach of its agreements contained herein. The Placement Agent shall
communicate to the Parent and the Company, orally or in writing, each offer to
purchase Notes and Series A Shares and may reject any proposed purchase of Notes
and Series A Shares as a whole or in part. Neither the Parent nor the Company
shall have any obligation to any prospective purchaser in respect of any
Securities proposed to be sold to such prospective purchaser until such
prospective purchaser has entered into the Subscription Agreement pursuant to
which purchasers will subscribe for the Notes and the Series A Shares. The
Parent and the Company agrees to pay or cause to be paid to the Placement Agent
placement fees with respect to its services as set forth in this Agreement in an

placement fees will be paid by the Parent and the Company to the Placement Agent
at the Closing Date by wire transfer of immediately available funds.

      The Parent and Company will deliver against payment of the purchase price
the Notes, in the form of one or more permanent global securities in definitive

representing all of the Notes. The Global Securities and the certificates
representing the Series A Shares to be purchased by each purchaser thereof shall
be made available for examination and packaging by the Placement Agent in The
City of New York not later than 10:00 A.M. on the last business day prior to the
Closing Date.

                                       14

<PAGE>

Placement Agent agrees that it and each of its affiliates will not offer or sell
the Notes or the Series A Shares in the United States by means of any form of
general solicitation or general advertising within the meaning of Rule 502(c)
under the Securities Act, including, but not limited to (i) any advertisement,
article, notice or other communication published in any newspaper, magazine or
similar media or broadcast over television or radio, or (ii) any seminar or
meeting whose attendees have been invited by any general solicitation or general
advertising.

     5.  Certain Agreements of the Issuers. Each of the Issuers, jointly and
severally, agrees with the Placement Agent that:

           (a)  The Parent and the Company will advise the Placement Agent
      promptly of any proposal to amend or supplement the Offering Document and
      will not effect such amendment or supplementation without the Placement
      Agent's consent. If, at any time prior to the completion of the placement
      of the Notes and the Series A Shares by the Placement Agent, any event
      occurs as a result of which the Offering Document as then amended or
      supplemented would include an untrue statement of a material fact or omit
      to state any material fact necessary in order to make the statements
      therein, in the light of the circumstances under which they were made, not
      misleading, or if it is necessary at any such time to amend or supplement
      the Offering Document to comply with any applicable law, the Parent and
      the Company promptly will notify the Placement Agent of such event and
      promptly will prepare, at its own expense, an amendment or supplement
      which will correct such statement or omission or effect such compliance.
      Neither the Placement Agent's consent to, nor the Placement Agent's
      delivery to offerees or investors of, any such amendment or supplement
      shall constitute a waiver of any of the conditions set forth in Section 6.

           (b)  The Company will deliver to each purchaser of the Notes and
      Parent will deliver to each purchaser of the Series A Shares, in
      connection with the sale of the Notes and the Series A Shares, a copy of
      the Offering Document, as amended and supplemented at the date of such
      delivery.

           (c)  The Parent and the Company will furnish to the Placement Agent
      copies of the Offering Document and all amendments and supplements
      thereto, in each case as soon as available and in such quantities as the
      Placement Agent reasonably requests, and the Parent and the Company will
      furnish to the Placement Agent on the date hereof three copies of the
      Offering Document signed by a duly authorized officer of each of the
      Parent and the 


                                       15

<PAGE>

      Company, one of which will include the independent accountants' reports
      therein manually signed by such independent accountants. At any time when
      the either of the Parent or the Company is not subject to Section 13 or
      15(d) of the Exchange Act, such entity will promptly furnish or cause to
      be furnished to the Placement Agent and, upon request of holders and
      prospective purchasers of the Securities, to such holders and purchasers,
      copies of the information required to be delivered to holders and
      prospective purchasers of the Securities pursuant to Rule 144A(d)(4) under
      the Securities Act in order to permit compliance with Rule 144A in
      connection with resales by such holders of the Securities. The Parent and
      the Company will pay the expenses of printing and distributing to the
      Placement Agent and the holders and the prospective purchasers of the
      Securities all such documents.

           (d)  The Parent and the Company will arrange for the qualification of
      the Securities for sale and will use their reasonable best efforts to
      arrange for the determination of their eligibility for investment under
      the laws of such jurisdictions as the Placement Agent designates and will
      continue such qualifications in effect so long as required for the resale
      of the Securities by the purchasers thereof provided that the Parent and
      the Company will not be required to qualify as a foreign corporation or to
      file a general consent to service of process in any such jurisdiction.

           (e)  During the period of five years hereafter, the Parent and the
      Company will furnish to the Placement Agent and, upon request, to each
      purchaser of the Securities, as soon as practicable after the end of each
      fiscal year, a copy of its annual report to stockholders for such year, if
      any; and the Parent and the Company will furnish to the Placement Agent
      and, upon request, to each purchaser of the Securities as soon as
      available, (i) a copy of each description of reports, notices or
      communications sent to securityholders or, if applicable, filed with
      foreign regulators or securities exchanges, and (ii) from time to time,
      such other information concerning the Parent or the Company as the
      Placement Agent may reasonably request.

           (f)  During the period of two years after the Closing Date, the
      Parent and the Company will, upon request, furnish to the Placement Agent
      and any holder of Securities a copy of the restrictions on transfer
      applicable to the Securities.

           (g)  [Intentionally omitted.]

<PAGE>

           (h)  During the period of two years after the Closing Date, none of
      the Issuers will be or become, an open-end investment company, unit
      investment trust or face-amount certificate company that is or is required
      to be registered under Section 8 of the Investment Company Act.

           (i)  The Issuers will pay all expenses incidental to the performance
      of their obligations under this Agreement, the Subscription Agreement and
      the Indenture, including (i) the fees and expenses of the Trustee and its
      professional advisers in connection with the Indenture and the Securities;
      (ii) all expenses in connection with the execution, issue, authentication,
      packaging and initial delivery of the Securities, the preparation and
      printing of this Agreement, the Indenture, the Notes, the Series A Shares,
      the Offering Document and amendments and supplements thereto, and any
      other document relating to the issuance, offer, sale and delivery of the
      Securities; (iii) the cost of listing the Offered Securities and
      qualifying the Offered Securities for trading in The Portal(SM) Market
      ("PORTAL"), the cost of obtaining CUSIP numbers and any expenses
      incidental thereto; (iv) any expenses (including fees and disbursements of
      counsel) incurred in connection with qualification of the Securities for
      sale under the laws of such jurisdiction as the Placement Agent designates
      and the printing of memoranda relating thereto; (v) any fees charged by
      investment rating agencies for the rating of the Securities; (vi) all
      costs and expenses of any Registration Statement, as set forth in the
      Registration Rights Agreement and the Investors Agreement and (vii)
      expenses incurred in distributing the Offering Document (including any
      amendments and supplements thereto) to the Placement Agent and the
      purchasers of the Notes and the Series A Shares. The Issuers will also pay
      or reimburse the Placement Agent (to the extent incurred by them and, upon
      the Company's request, only upon presentation to the Company of
      documentation reasonably evidencing the same) for all travel expenses of
      the Placement Agent and the Parent's and the Company's officers and
      employees and any other expenses of the Placement Agent, the Parent and
      the Company in connection with attending or hosting meetings with
      prospective purchasers of the Notes and the Series A Shares.

           (j)  In connection with the offering, until the Placement Agent shall
      have notified the Parent and the Company of the completion of the
      placement of the Notes and the Series A Shares, none of the Parent, the
      Company or any of their affiliates has or will, either alone or with one
      or more other persons, bid for or purchase, for any account in which it or
      any of its affiliates has a beneficial interest, any Securities or attempt
      to induce any person to purchase 


                                       17

<PAGE>

      any Securities, and they shall not make bids or purchases for the purpose
      of creating actual, or apparent, active trading in, or of raising the
      price of, the Securities.

           (k)  For a period of 180 days after the date of the sale of the Notes
      and the Series A Shares to the purchasers thereof, none of the Issuers
      will offer, sell, contract to sell, announce their intention to sell,
      pledge or otherwise dispose of, directly or indirectly, any United States
      dollar-denominated debt securities issued or guaranteed by any of the
      Issuers and having a maturity of more than one year from the date of issue
      without the prior written consent of the Placement Agent. None of the
      Issuers will at any time offer, sell, contract to sell, pledge or
      otherwise dispose of, directly or indirectly, any securities under
      circumstances where such offer, sale, pledge, contract or disposition
      would cause the exemption afforded by Section 4(2) of the Securities Act
      or the safe harbor of Regulation S thereunder to cease to be applicable to
      the offer and sale of the Securities.

           (l)  The Parent and the Company agree that they will use the net
      proceeds to them from the sale of the Securities in the manner described
      in the Offering Document under the caption "Use of Proceeds". The Company
      further agrees that on the Closing Date it will, in accordance with
      respective terms of the Indenture, dated as of March 15, 1994, as
      supplemented, between Envirotest, the guarantors named therein and First
      Trust National Association, as trustee (the "2001 Trustee"), pursuant to
      which the 2001 Notes were issued (the "2001 Indenture") and the Indenture,
      dated as of April 1, 1993, as supplemented, between Envirotest, the
      guarantors named therein and First Trust National Association, as trustee
      (the "2003 Trustee"), pursuant to which the 2003 Notes were issued (the
      "2003 Indenture"), (i) defease any and all of the 2001 Notes and the 2003
      Notes remaining outstanding on such Closing Date after consummation of the
      Debt Offers, in accordance with Section 8.1 of the 2001 Indenture and
      Section 8.01 of the 2003 Indenture, respectively, or (ii) give such
      notices to the 2001 Trustee and the 2003 Trustee, as applicable, and take
      such other actions as may be required to exercise, at the earliest
      practicable date, its optional redemption right under Section 3.1 of the
      2001 Indenture and Section 3.01 of the 2003 Indenture, with respect to any
      2001 Notes or 2003 Notes remaining outstanding after consummation of the
      Debt Offers.

           (m)  In connection with the original distribution of the Notes and
      the Series A Shares, the Issuers agree that, prior to any offer or sale of
      the 


                                       18

<PAGE>

      Notes by the Company or the Series A Shares by the Parent, the Placement
      Agent and counsel for the Placement Agent shall have the right to make
      reasonable inquiries into the business of the Parent, the Company and
      their subsidiaries. The Issuers will provide each prospective purchaser
      the opportunity to ask questions of, and receive answers from, the
      officers, employees and representatives of the Issuers concerning the
      terms and conditions of the offering and to obtain any other additional
      information about the Parent, the Company and their subsidiaries and the
      Securities, to the extent the officers and employees of the Issuers
      possess the same or can acquire it without unreasonable effort or expense.

           (n)  The Issuers will furnish or cause to be furnished to the
      Placement Agent such information as the Placement Agent reasonably
      believes appropriate to its appointment as Placement Agent, including
      without limitation such information as the Placement Agent reasonably
      believes is necessary in connection with its assistance in the preparation
      of, or for inclusion in the Offering Document (all such information so
      furnished being hereinafter referred to as the "Information"). It is also
      understood that the Parent and the Company may make available to
      prospective purchasers of the Notes and the Series A Shares additional
      material, data or other information (whether oral or written) relating to
      the Parent or the Company (the "Company Data"). The Issuers recognize and
      confirm that: (i) in performing the services contemplated by this
      Agreement, the Placement Agent will use and rely primarily on the
      Information and on other information available from generally recognized
      public sources without having independently verified the same; (ii) the
      Placement Agent does not assume responsibility for the accuracy or
      completeness of the Offering Document, the Information, the Company Data
      and such other information; and (iii) the Placement Agent will not make an
      appraisal of any of the assets owned or managed by the Issuers as part of
      the services to be performed by it hereunder except in connection with its
      valuation of the Series A Common Stock.

           (o)  Offers and sales of the Notes and the Series A Shares will be
      made only by the Issuers to persons whom the Issuers reasonably believe to
      be institutional "accredited investors" within the meaning of Rule
      501(a)(1), (2), (3) or (7) under the Securities Act ("Institutional
      Accredited Investors") and in a manner not involving a public offering
      with the meaning of Section 4 of the Securities Act.

           (p)  No general solicitation or general advertising (within the


                                       19

<PAGE>

      meaning of Rule 502(c) under the Securities Act) will be used in
      connection with the offering of the Notes and the Series A Shares. If
      required, the Issuers will file in a timely manner with the Commission any
      notices with respect to the Securities required by Regulation D and will
      furnish to the Placement Agent promptly thereafter a signed copy of each
      such notice.

           (q)  The transfer restrictions and the other provisions set forth in
      (i) the Indenture and the Registration Rights Agreement with respect to
      the Notes and (ii) the Investors Agreement, the Share Price Adjustment
      Agreement and the certificates representing the Series A Shares with
      respect to such Shares, including the legends required thereby or
      appearing thereon, shall apply to the Securities except as otherwise
      agreed by the Issuers and the Placement Agent. Following the sale of the
      Notes by the Company and the Series A Shares by the Parent to purchasers
      thereof pursuant to the terms of the Subscription Agreement, the Placement
      Agent (solely in its capacity as Placement Agent) shall not be liable or
      responsible to any of the Issuers for any losses, damages or liabilities
      suffered or incurred by any of the Issuers, including any losses, damages
      or liabilities under the Securities Act, arising from or relating to any
      sale, resale or transfer of any Security except for any such loss, damage
      or liability incurred by the Company as a result of gross negligence or
      willful misconduct on the part of the Placement Agent or any of its
      affiliates.

           (r)  Each of the Issuers agrees that it will not and will cause its
      affiliates not to make any offer or sale of securities of any of the
      Issuers of any class if, as a result of the doctrine of "integration"
      referred to in Rule 502 under the Securities Act, such offer or sale would
      render invalid (for the purpose of the sale of the Notes and the Series A
      Shares by the Company and the Parent to the purchasers thereof) the
      exemption from the registration requirements of the Securities Act
      provided by Section 4(2) thereof or otherwise.

     6.  Conditions of the Obligations of the Placement Agent. The obligations
of the Placement Agent hereunder will be subject to the accuracy of the
representations and warranties on the part of the Issuers herein, to the
accuracy of the statements of officers of the Issuers made pursuant to the
provisions hereof, to the performance by the Issuers of their respective
obligations hereunder and to the following additional conditions precedent and
conditions subsequent:

           (a)  The Placement Agent shall have received a letter, dated the


                                       20

<PAGE>

      Closing Date and satisfactory to the Placement Agent and the purchasers of
      Securities, of PriceWaterhouseCoopers LLP addressed to the Placement
      Agent, the Parent, the Company and the purchasers of the Securities
      pursuant to this Agreement confirming that they are independent public
      accountants within the meaning of the Securities Act and the applicable
      published rules and regulations thereunder ("Rules and Regulations") and
      to the effect that:

                 (i)  in their opinion the financial statements and schedules
            examined by them and included in the Offering Document comply as to
            form in all material respects with the applicable accounting
            requirements of the Securities Act and the related published Rules
            and Regulations;

                 (ii)  they have performed the procedures specified by the
            American Institute of Certified Public Accountants for a review of
            interim financial information as described in Statement of Auditing
            Standards No. 71, Interim Financial Information, on the unaudited
            financial statements included in the Offering Document;

                 (iii)  on the basis of the review referred to in clause (ii)
            above, a reading of the latest available interim financial
            statements of the Parent and the Company, and of all subsidiaries of
            the Company for which such interim financial statements are
            provided, inquiries of officials of the Parent, the Company, and of
            such subsidiaries, who have responsibility for financial and
            accounting matters and other specified procedures, nothing came to
            their attention that caused them to believe that:

                       (A)  the unaudited financial statements included in the
                  Offering Document do not comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Securities Act and the related published Rules and Regulations
                  or any material modifications should be made to such unaudited
                  financial statements for them to be in conformity with
                  generally accepted accounting principles;

                       (B)  at the date of the latest available balance sheet
                  read by such accountants, or at a subsequent specified date
                  not more than three business days prior to the Closing Date,
                  there was any change in the capital stock or any material
                  increase in 


                                       21

<PAGE>

                  long-term debt of the Parent or the Company and its
                  consolidated subsidiaries or, at the date of the latest
                  available balance sheet read by such accountants, there was
                  any decrease in consolidated net current assets, as compared
                  with amounts shown on the latest balance sheet included in the
                  Offering Document, or

                       (C)  for the period from the closing date of the latest
                  income statement included in the Offering Document to the
                  closing date of the latest available income statement read by
                  such accountants there were any decreases, as compared with
                  the corresponding period of the previous year and with the
                  period of corresponding length ended the date of the latest
                  income statement included in the Offering Document, in
                  consolidated net sales, net operating income or in the total
                  or per share amounts of consolidated income before
                  extraordinary items or net income; except in all cases set
                  forth in clauses (B) and (C) above for changes, increases or
                  decreases which the Offering Document disclose have occurred
                  or may occur or which are described in such letter;

                 (iv)  they have performed the procedures specified by the
            American Institute of Certified Public Accountants for a review on
            pro forma financial information as described in Statement on
            Standards for Attestation Engagement No. 1, Reporting on Pro Forma
            Financial Statements, on the pro forma financial statements included
            in the Offering Document;

                 (v)  on the basis of the review referred to in clause (iv)
            above, nothing came to their attention that caused them to believe
            that the pro forma financial statements included in the Offering
            Document do not comply as to form in all material respects with the
            applicable accounting requirements of the Securities Act and the
            related published Rules and Regulations or that the pro forma
            adjustments have not been properly applied to the historical amounts
            in the compilation of those statements; and

                 (vi)  they have compared specified dollar amounts (or
            percentages derived from such dollar amounts) and other financial
            information contained in the Offering Document (in each case to the


                                       22

<PAGE>

            extent that such dollar amounts, percentages and other financial
            information are derived from the general accounting records of the
            Parent or the Company and its subsidiaries subject to the internal
            controls of the Company's accounting system or are derived directly
            from such records by analysis or computation) with the results
            obtained from inquiries, a reading of such general accounting
            records and other procedures specified in such letter and have found
            such dollar amounts, percentages and other financial information to
            be in agreement with such results, except as otherwise specified in
            such letter.

                 (vii)  the presentation of Management's Discussion and Analysis
            of Financial Condition and Results of Operations in the Offering
            Document includes, in all material respects, the required elements
            of the rules and regulations adopted by the Commission; the
            historical financial amounts included therein have been accurately
            derived, in all material respects, from the Company's financial
            statements; and the underlying information, determination, estimates
            and assumptions of the Company provide a reasonable basis for the
            disclosures contained therein.

           (b)  Subsequent to the execution and delivery of this Agreement,
      there shall not have occurred (i) a change in U.S. or international
      financial, political or economic conditions or currency exchange rates or
      exchange controls as would, in the reasonable judgment of the Placement
      Agent, be likely to prejudice materially the success of the proposed issue
      and sale of the Notes and the Series A Shares, whether in the primary
      market or in respect of dealings in the secondary market, or (ii) (A) any
      change, or any development or event involving a prospective change, in the
      condition (financial or other), business prospects, properties or results
      of operations of the Parent and its subsidiaries taken as a whole, which,
      in the reasonable judgment of the Placement Agent, is material and adverse
      to the Parent and its subsidiaries taken as a whole and makes it
      impractical or inadvisable to proceed with completion of the issuance or
      the sale of and payment for the Securities; (B) any downgrading in the
      rating of any debt securities of the Parent, the Company or any of their
      subsidiaries by any "nationally recognized statistical rating
      organization" (as defined for purposes of Rule 436(g) under the Securities
      Act), or any public announcement that any such organization has under
      surveillance or review its rating of any debt securities of the Parent,
      the Company or any of their subsidiaries (other than an announcement with


                                       23

<PAGE>

      positive implications of a possible upgrading, and no implication of a
      possible downgrading, of such rating); (C) any suspension or limitation of
      trading in securities generally on the New York Stock Exchange or the
      Nasdaq National Market, or any setting of minimum prices for trading on
      such exchange, or any suspension of trading of any securities of the
      Parent, the Company or any of their subsidiaries on any exchange or in the
      over-the-counter market; (D) any banking moratorium declared by U.S.
      Federal or New York authorities; or (E) any outbreak or escalation of
      major hostilities in which the United States is involved, any declaration
      of war by Congress or any other substantial national or international
      calamity or emergency if, in the reasonable judgment of the Placement
      Agent, the effect of any such outbreak, escalation, declaration, calamity
      or emergency makes it impractical or inadvisable to proceed with
      completion of the issuance or sale of and payment for the Notes and the
      Series A Shares.

           (c)  The Placement Agent shall have received an opinion or opinions,
      dated such Closing Date, of counsel for the Issuers, substantially to the
      effect that:

                 (i)  Each of the Parent, the Company and each subsidiary of the
            Company was duly incorporated and is in good standing under the laws
            of its jurisdiction of incorporation, with corporate power and
            authority to own its properties and conduct its businesses as
            described in the Offering Document.

                 (ii)  Each of the Transaction Documents (except for the
            Envirotest Agreement and the Transervice Agreement) has been duly
            authorized, executed and delivered by each of the Parent, the
            Company and their subsidiaries (to the extent each is a party
            thereto); each of the Transaction Documents conforms to the
            description thereof contained in the Offering Document (to the
            extent described therein); and each of the Transaction Documents
            (other than this Agreement and the Subscription Agreement)
            constitutes valid and legally binding obligations of each of the
            Parent, the Company and their subsidiaries (to the extent each is a
            party thereto) enforceable in accordance with its respective terms,
            subject to bankruptcy, insolvency, fraudulent transfer,
            reorganization, moratorium and similar laws of general applicability
            relating to or affecting creditors' rights and to general equity
            principles and, as to rights of indemnification and contribution, to
            principles of public policy and federal and state 


                                       24

<PAGE>

            securities laws relating thereto.

                 (iii)  The Notes, the Guarantees and the Series A Shares
            conform in all material respects to the description thereof in the
            Offering Document.

                 (iv)  The Notes and the Guarantees have been duly authorized
            and executed by the Company and the Guarantors, respectively, and,
            when the Notes are authenticated in the manner provided for in the
            Indenture and delivered against payment of the purchase price
            therefor, the Notes and the Guarantees will constitute valid and
            binding obligations of the Company and the Guarantors, respectively,
            enforceable against the Company and the Guarantors, respectively, in
            accordance with their terms, subject to bankruptcy, insolvency,
            fraudulent transfer, reorganization, moratorium and similar laws of
            general applicability relating to or affecting creditors' rights and
            to general equity principles and, as to rights of indemnification
            and contribution, to principles of public policy and federal and
            state securities laws relating thereto.

                 (v)  The Series A Shares have been duly authorized and, when
            issued and delivered to and paid for by the purchasers thereof in
            accordance with the terms of the Subscription Agreement, will have
            been validly issued and fully paid and nonassessable.

                 (vi)  [Intentionally omitted.]

                 (vii)  To our knowledge, there are no preemptive rights or
            similar rights that have not been waived to subscribe for or
            purchase the Securities upon their issuance and sale by the Issuers
            pursuant to this Agreement and the Subscription Agreement. To our
            knowledge, no securityholder of any Issuer has any right that has
            not been waived to require such Issuer to register the sale of any
            securities owned by such securityholder under the Securities Act in
            the offering and sale contemplated by this Agreement and the
            Subscription Agreement.

                 (viii)  The execution, delivery of, and performance by each of
            the Parent, the Company and their subsidiaries (to the extent each
            is a party thereto) of its obligations under each of the Transaction
            Documents (including the issuance and sale of the Securities) and


                                       25

<PAGE>

            compliance with the terms and provisions thereof will not result in
            a breach or violation of any of the terms and provisions of, or
            constitute a default under, any statute, any rule, regulation or
            order of any governmental agency or body or any court, domestic or
            foreign, having jurisdiction over the Parent, the Company or any
            subsidiary of the Company or any of their respective properties, or
            the charter or by-laws of the Parent, the Company or any such

            obtained or made by the Parent, the Company or any subsidiary of the
            Parent or the Company for the consummation of the Transactions or
            otherwise in connection with the issuance and sale of the
            Securities, other than those consents, approvals, authorizations,

            the Securities and as may be required under the Securities Act in
            connection with the Registration Rights Agreement and the Investors
            Agreement.

                 (xi)  It is not necessary in connection with the offer, sale

            issued, are fully paid and nonassessable and conform in all material
            respects to the description thereof contained in the Offering
            Document; the Parent is the record owner of all of the issued and

            through subsidiaries, is the record owner of all of the issued and
            outstanding capital stock of each subsidiary of the Company, and the
            securityholders of the Parent, the Company and their subsidiaries
            have no preemptive rights with respect to the Securities.

                 (xiii)  Except as set forth in the Offering Document or any
            Transaction Document, there are no contracts, agreements or
            understandings known to such counsel between the Parent, the Company
            or any of their subsidiaries and any person granting such person the
            right to require the Parent, the Company or any of their

            Act with respect to any securities of the Parent, the Company or any

            include such securities in any registration statement filed by the
            Parent, the Company or any of their subsidiaries under the
            Securities Act.

                 (xiv)  The statements under the captions "Business--Legal
            Proceedings," "Description of Other Indebtedness," "Description of
            the Notes," "Description of Capital Stock" and "Certain United
            States Federal Income Tax Considerations" in the Offering Document,
            insofar as such statements constitute a summary of the legal
            matters, documents or proceedings referred to therein, fairly
            present in all material respects the information called for with
            respect to such legal matters, documents and proceedings as if such
            Offering Document were a prospectus included in a registration
            statement on Form S-1.

                 (xv)  None of the Parent, the Company or any of their

            in default in the performance of any obligation, agreement, covenant
            or condition contained in any indenture, loan agreement, mortgage,
            lease or other agreement or instrument as set forth on Schedule B
            attached hereto.

                 (xvi)  Based solely on discussions with the Parent, the 


                                       27

<PAGE>

            Company or any of their subsidiaries but without independent
            investigation or verification thereof, such counsel does not know of
            any legal or governmental proceedings pending or threatened to which
            the Parent, the Company or any of their subsidiaries is or could be
            a party or to which any of their respective property is or could be
            subject, which might result, singly or in the aggregate, in a
            Material Adverse Effect.

                 (xvii)  Based upon our participation in the preparation of the
            Offering Document, but without independent check and verification,
            nothing has come to our attention which causes us to believe that as
            of its date or as of the Closing Date the Offering Document as
            amended or supplemented (other than the financial statements and
            other financial data included therein or omitted therefrom, as to
            which we express no belief) contained or contains an untrue
            statement of a material fact or omitted or omits to state a material
            fact necessary to make the statements therein, in light of the
            circumstances under which they were made, not misleading.

           (d)  The Placement Agent shall have received from Skadden, Arps,
      Slate, Meagher & Flom LLP, counsel for the Placement Agent, such opinion
      or opinions, dated such Closing Date, with respect to such matters as the
      Placement Agent may reasonably require, and the Issuers shall have
      furnished to such counsel such documents as they request for the purpose
      of enabling them to pass upon such matters.

           (e)  The Placement Agent shall have received a certificate, dated the
      Closing Date, of the President or any Vice President and a principal
      financial or accounting officer of each of the Issuers in which such
      officers after reasonable investigation shall state that the
      representations and warranties of such company in this Agreement are true
      and correct as of such date, that such company has complied with all
      agreements and satisfied all conditions on its part to be performed or
      satisfied hereunder at or prior to the Closing Date, and that, subsequent
      to the date of the most recent financial statements in the Offering
      Document, there has been no Material Adverse Change, nor any development
      or event involving a prospective Material Adverse Change, and there has
      been no dividend or distribution of any kind declared, paid or made by the
      Company on any class of its capital stock, except as disclosed in or
      contemplated by the Offering Document or as described in such certificate.

      and pursuant to documentation, satisfactory to the Administrative Agent
      (including, without limitation, provisions of any such note relating to
      subordination, payments of principal and interest and the exercise of
      remedies) under the Credit Agreement.

      accordance with the terms thereof; and (iii) the Company shall have
      provided to the Placement Agent and counsel to the Placement Agent copies
      of all Transaction Documents delivered to the parties relating to the
      Transactions (including but not limited to legal opinions relating
      thereto). To the extent the conditions in any of the agreements and
      documents referred to in clause (i) above permit any person or persons to


                                       29

<PAGE>

      waive compliance with such condition, or require that a document, opinion
      or other instrument or any event or condition be acceptable or
      satisfactory to any person or persons, for purposes of this Agreement,
      such condition shall be complied with only if waived by the Placement
      Agent and such document, opinion or other instrument and such events or

      purposes of this Agreement without the consent of the Placement Agent.

      opinions delivered on behalf of the Company in connection with the

      them from Murray, Devine & Co. in form and substance reasonably
      satisfactory to the purchasers of the Notes and the Series A Shares that
      the Transactions and the application of the net proceeds therefrom will
      not render the Parent, the Company or any of their subsidiaries insolvent,
      leave the Parent, the Company or any of their subsidiaries with inadequate
      or unreasonably small capital with which to conduct business or result in
      the Parent, the Company or any of their subsidiaries incurring
      indebtedness beyond its ability to repay as such indebtedness matures.

           (l)  The Placement Agent shall have received a certificate, dated the
      Closing Date, of the President or any Vice President of the Company in
      which such officer after reasonable investigation shall state that (i)
      each of the Company and its subsidiaries has such permits, licenses,
      consents, exemptions, franchises, authorizations and other approvals
      ("permits") of, and has made all filings with and notice to, all
      governmental or regulatory authorities and self-regulatory organizations
      and all courts and other tribunals, including, without limitation, under
      any applicable environmental laws, as are necessary to own, lease, license
      and operate its respective properties and to conduct its business, except
      where the failure to have any such permit or to make any such filing or
      notice would not, singly or in the aggregate, have a Material Adverse
      Effect, (ii) each such permit is valid and in full force and effect and
      each of the Company and its subsidiaries is in compliance with all the
      terms and conditions thereof and with the rules and regulations of the
      authorities and 


                                       30

<PAGE>

      governing bodies having jurisdiction with respect thereto, (iii) no event
      has occurred (including the receipt of any notice from any authority or
      governing body) which allows or, after notice or elapse of time or both,
      would allow for revocation, suspension or termination of any such permit
      or has resulted or, after notice or lapse of time or both, would result,
      in any other impairment of the rights of the holder of any such permit,
      and (iv) such permits contain no restrictions that are burdensome to the
      Company or any of its subsidiaries except where such failure to be valid
      and in full force and effect or to be in compliance, the occurrence of any
      such event or the presence of any such restriction would not, singly or in
      the aggregate, have a Material Adverse Effect.

           (m)  Upon consummation of the Envirotest Sale, the Company shall
      provide notice to the Placement Agent of such sale and shall provide the
      Placement Agent with an executed copy of the Envirotest Agreement.

      trading in the PORTAL market.

           (p)  The Placement Agent shall have received evidence satisfactory to
      it that all conditions set forth herein shall have been met and such
      further certificates and documents as the Placement Agent shall reasonably
      request.

           (q)  The Company will furnish the Placement Agent with such conformed
      copies of such opinions, certificates, letters and documents as the
      Placement Agent reasonably requests. The Placement Agent may in its sole
      discretion waive compliance with any conditions to the obligations of the
      Placement Agent hereunder.

           (r)  As of the Closing Date, the Parent and the Company shall have


                                       31

      received CUSIP numbers for the Notes and the Series A Shares and will
      provide the Placement Agent with such CUSIP numbers.

           (s)  On the Closing Date, the Placement Agent shall have received the
      final Offering Document, in a form satisfactory to the Placement Agent,
      the purchasers of Securities and their respective counsel.

     7.  Indemnification and Contribution. (a) Each of the Issuers, jointly and
severally, will indemnify and hold harmless the Placement Agent against any
losses, claims, damages or liabilities, joint or several, to which the Placement
Agent may become subject, under the Securities Act or the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) any untrue statement or
alleged untrue statement of any material fact contained in the Offering
Document, or any amendment or supplement thereto, or in the Information or
Company Data furnished or made available by the Parent or the Company directly,
through the Placement Agent or otherwise, to any prospective purchaser of the
Notes and the Series A Shares or its representatives, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and will reimburse the
Placement Agent for any legal or other expenses reasonably incurred by the
Placement Agent in connection with investigating or defending any such loss,
claim, damage, liability or action as such expenses are incurred upon
presentation of documentation reasonably evidencing the same or (ii) the
engagement of the Placement Agent pursuant to, and the performance by the
Placement Agent of the services contemplated by, this Agreement;

           (b)  [Intentionally omitted.]

           (c)  Promptly after receipt by an indemnified party under this
      Section of notice of the commencement of any action, such indemnified
      party will, if a claim in respect thereof is to be made against the
      indemnifying party under subsection (a) above, notify the indemnifying
      party of the commencement thereof; but the omission so to notify the
      indemnifying party will not relieve it from any liability which it may
      have to any indemnified party otherwise than under subsection (a) above.
      In case any such action is brought against any indemnified party and it
      notifies the indemnifying party of the commencement thereof, the
      indemnifying party will be entitled to participate therein and, to the
      extent that it may wish, jointly with any other indemnifying party
      similarly notified, to assume the defense thereof, with counsel reasonably
      satisfactory to such indemnified party (who shall not, except with the
      consent 


                                       32

<PAGE>

      of the indemnified party (which consent shall not be unreasonably
      withheld), be counsel to the indemnifying party), and after notice from
      the indemnifying party to such indemnified party of its election so to
      assume the defense thereof, the indemnifying party will not be liable to
      such indemnified party under this Section for any legal or other expenses
      subsequently incurred by such indemnified party in connection with the
      defense thereof other than reasonable costs of investigation. No
      indemnifying party shall, without the prior written consent of the
      indemnified party, effect any settlement of any pending or threatened
      action in respect of which any indemnified party is or could have been a
      party and indemnity could have been sought hereunder by such indemnified
      party unless such settlement includes an unconditional release of such
      indemnified party from all liability on any claims that are the subject
      matter of such action.

           (d)  If the indemnification provided for in this Section is
      unavailable or insufficient to hold harmless an indemnified party under
      subsection (a) above, then each indemnifying party shall contribute to the
      amount paid or payable by such indemnified party as a result of the
      losses, claims, damages or liabilities referred to in subsection (a) above
      (i) in such proportion as is appropriate to reflect the relative benefits
      received by the Issuers on the one hand and the Placement Agent on the
      other from the issuance and sale of the Notes and the Series A Shares or
      (ii) if the allocation provided by clause (i) above is not permitted by
      applicable law, in such proportion as is appropriate to reflect not only
      the relative benefits referred to in clause (i) above but also the
      relative fault of the Issuers on the one hand and the Placement Agent on
      the other in connection with the statements or omissions which resulted in
      such losses, claims, damages or liabilities as well as any other relevant
      equitable considerations. The relative benefits received by the Issuers on
      the one hand and the Placement Agent on the other shall be deemed to be in
      the same proportion as the total net proceeds from the issuance and sale
      of the Notes and the Series A Shares (before deducting expenses) received
      by the Parent and the Company bear to the total placement fees received by
      the Placement Agent from the Parent and the Company. The relative fault
      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 any of the Issuers or the Placement Agent and the parties' relative
      intent, knowledge, access to information and opportunity to correct or
      prevent such untrue statement or omission. The amount paid by an
      indemnified party as a result of the losses, claims, damages or
      liabilities referred to in the first sentence of this subsection 


                                       33

<PAGE>

      (d) shall be deemed to include any legal or other expenses reasonably
      incurred by such indemnified party in connection with investigating or
      defending any action or claim which is the subject of this subsection (d).
      Notwithstanding the provisions of this subsection (d), the Placement Agent
      shall not be required to contribute any amount in excess of the actual
      fees paid to the Placement Agent.

           (e)  The obligations of the Issuers under this Section shall be in
      addition to any liability which the Issuers may otherwise have and shall
      extend, upon the same terms and conditions, to the Placement Agent, its
      representatives, officers and directors and each person, if any, who
      controls the Placement Agent within the meaning of the Securities Act or
      the Exchange Act; and the obligations of the Placement Agent under this
      Section shall be in addition to any liability which the Placement Agent
      may otherwise have and shall extend, upon the same terms and conditions to
      each Company, its representatives, officers and directors and person, if
      any, who controls the Issuers within the meaning of the Securities Act or
      the Exchange Act.

     8.  Services; Default. In connection with the services to be rendered
hereunder, the Placement Agent shall act as an independent contractor, and any
duties of the Placement Agent arising out of its engagement pursuant to this
Agreement shall be owed solely to the Parent and the Company. In soliciting
orders from others to purchase Notes and Series A Shares, the Placement Agent is
acting solely as an agent for the Parent and the Company, and not as a
principal. The Placement Agent will not have any liability to the Parent and the
Company in the event any purchaser whose offer to purchase Notes and Series A
Shares has been accepted by the Parent or the Company does not perform its
obligations to the Parents or the Company. If the Parent or the Company shall
default on their obligation to deliver Notes and Series A Shares to a purchaser
thereof whose offer they have accepted, the Parents or the Company shall
indemnify the Placement Agent against any loss, claim, or damage arising from or
as a result of such default by the Parent or the Company.

     9.  Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of
each of the Issuers or its officers and of the Placement Agent set forth in or
made pursuant to this Agreement will remain in full force and effect, regardless
of any investigation, or statement as to the results thereof, made by or on
behalf of the Placement Agent, the Issuers or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Notes and the Series A Shares. If for
any reason the purchase of the Notes and the Series A Shares 


                                       34

<PAGE>

by the purchasers thereof is not consummated, the Issuer shall remain
responsible for the expenses (including fees and disbursements of counsel) to be
paid or reimbursed by them pursuant to Section 5(i) and the obligations of each
of the Issuers and the Placement Agent pursuant to Section 7 shall remain in
effect; provided, however, that the Companies shall have no obligations under
either Section 5(i) or Section 7 if this Agreement is terminated pursuant to
Section 8 or as a result of the occurrence of any event specified in clause (C),
(D) or (E) of Section 6(b)(ii) or if the purchase of the Securities is not
consummated due to a material breach of, or default under, this Agreement by the
Placement Agent; if any Notes and Series A Shares have been purchased hereunder
and under the Subscription Agreement, the Issuers shall remain responsible for
the expenses to be paid or reimbursed by them pursuant to Section 5 and the
obligations of the Issuers pursuant to Section 7 shall remain in effect, and the
representations and warranties in Section 2 and all other obligations under
Section 5 shall also remain in effect.

     10.  Notices. All communications hereunder will be in writing and, if sent
to the Placement Agent will be mailed, delivered or telegraphed and confirmed to
the Placement Agent at Credit Suisse First Boston Corporation, Eleven Madison
Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking Department B

     11.  Successors. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the representatives,
officers and directors controlling persons referred to in Section 7, and no
other person will have any right or obligation hereunder, except that holders of
Securities shall be entitled to enforce the agreements for their benefit
contained in the second and third sentences of Section 5(c) hereof against the
Parent and the Company as if such holders were parties thereto.

     12.  Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such

     (a)  by replacing paragraph 1 of Schedule "2", Contract Fee Schedule, with
          the following:

          "1.  FEE COLLECTION AND DEPOSIT AND CONTRACTOR PAYMENT

          The Contractor shall collect all fees to be paid at the time of
          inspection at the Vehicle Emissions Inspection Centres.  Fees
          collected shall be $15.00 (plus Goods and Services Tax if it is
          determined to be applicable) per emissions inspection, whether a first
          inspection or a reinspection.  Additional fees may be collected for
          combined safety and emissions inspection provided the motorist
          volunteers for the safety inspection as provided in paragraph 8 below.
          The Contractor shall allow fee payment by cash or approved cheques. 
          (Contractor will develop criteria for approving cheques).  From time
          to time the Superintendent may change the amount of the fees to be
          collected by the Contractor so long as the fees collected, in
          combination with other appropriated monies, are adequate to compensate
          the Contractor according to the Terms of this Agreement.

          The Contractor shall deposit the amount of all fees collected to an
          account designated by the Contractor for such purpose.  Deposit of the
          fees collected by the Contractor shall be made in a manner approved by
          the Program Administrator to allow reconciliation of the fees
          collected by the Contractor to amounts deposited.  The Contractor
          shall transfer to an account designated by the Province the amount of
          the fees collected less the amount due the Contractor from the fees
          collected.  The Contractor shall transfer to the Province that net
          amount prior to the end of the banking business day following the day
          of the collection.

          All fees collected by the Contractor are the responsibility of the
          Contractor until they are deposited to the Province's account.  The
          Contractor shall take whatever steps are necessary to ensure the
          security of collected fees, and shall reimburse the Province for any
          monies due the Province that are lost, stolen, destroyed, or not
          deposited to the Province's account for any other reason.";

     (b)  by deleting the date "June 30, 1999" in both subsection 14.07(f) and
          in section 26.05 and substituting the date "August 31, 1999" in both
          cases; and

     (c)  by deleting the phrase "giving possession" in subsection 14.02(d) and

                                 STATE OF ILLINOIS
                          ENVIRONMENTAL PROTECTION AGENCY
                               AMENDMENT NUMBER 3 TO
                              AGENCY SERVICE AGREEMENT

     In consideration of the execution of the Professional Services Agreement
Number VI-8302, executed May 19, 1997 (hereinafter, "Enhanced I/M Agreement"),
between the Illinois Environmental Protection Agency (hereinafter, "Agency") and
Envirotest Illinois, Inc. (hereinafter, "Contractor"), whose address is 246
Sobrante Way, Sunnyvale, CA 94086, the parties hereto further agree as follows:

                                     WITNESSETH:

     WHEREAS, the Agency and the Contractor entered into the Enhanced I/M
Agreement hereinabove described, pursuant to which the Agency engaged the
Contractor to perform services in connection with the Illinois Vehicle Emissions
Inspection Law of 1995;

     WHEREAS, the Enhanced I/M Agreement incorporates the Scope of Services for
the Extension of the Vehicle Emission Test Program, dated October 31, 1990
(hereinafter, "Scope"), the License Agreement, dated October 31, 1990, the
Contractor's Technical Proposal, dated September 21, 1990, and each of seven (7)
Amendments subsequently entered into pursuant to the terms of the Agreement
(collectively contained in Appendix 10.20 of the Enhanced I/M Agreement, and
hereinafter referred to as the "Basic I/M Agreement");

     WHEREAS, currently, owners of vehicles subject to the program receive a
two-year new vehicle model year exemption and are therefore initially notified
of the requirement for emissions testing beginning in the second year after the
vehicle's model year and thereafter are notified and tested biennially;

     WHEREAS, P.A. 90-475 grants the Agency a degree of discretion within
defined limits to choose the year that a new model year vehicle is initially
notified to begin its biennial emissions testing cycle;

     WHEREAS, the Agency has elected, and the Contractor agrees, that the
current two-year new model vehicle exemption be extended to a four-year new
model vehicle exemption beginning either January 1, 1998, or the date of
execution of this amendment, whichever date is later, and continue through the
period of the Start-Up Phase;

     WHEREAS, the current Reimbursable Test Fee formula is based, in part, on a
higher volume of tests than will exist when the initial notification schedule is
modified to accommodate the change from a two-year new model vehicle exemption
to a four-year new model vehicle exemption, and the parties recognize that the
formula requires modification to take into account the effects of this change to
the operating cost;

<PAGE>

     WHEREAS, to reflect the further understandings and agreement of the Agency
and the Contractor, the Agency and the Contractor have determined it to be in
their best interests to enter into this Amendment Number 3 to the Enhanced I/M
Agreement;

NOW THEREFORE, in consideration of the mutual promises contained herein, the
parties hereto agree as follows:

1.   No later than November 19, 1997, the Contractor shall implement all
     software changes necessary to prevent the scheduling and assignment for
     testing of vehicles subject to the four-year new model vehicle exemption. 
     This includes, but is not limited to, modification to the ZIPSCAN report
     generation program to update the definition of "eligible unassigned
     vehicles," and the modification of the MAILING program to limit the
     selection of vehicles for initial assignment and mailing to vehicles of
     model year equal to, or less than, the assigned date year minus four, with
     the exception for noncomplying vehicles registered to new owner(s).  After
     January 1, 1998, or the execution date of this amendment, whichever date is
     later, the Contractor shall not receive reimbursement for tests performed
     on vehicles subject to the four-year new model vehicle exemption, unless
     specifically assigned by the Agency, or assigned for testing prior to
     January 1, 1998, or the execution date of this amendment, whichever date
     is later.

2.   The "Reimbursable Test Fee" formula contained in the Basic I/M Agreement at
     Section 8.2.2. of the Scope of Services (as amended by Paragraph 13 of
     Amendment 6 to the Basic I/M Agreement), shall be amended as described
     below, and shall apply ONLY to reimbursable tests posted to the transaction
     database between either January 1, 1998, or the execution date of this
     contract amendment, whichever date is later, and the end of the Start-Up
     Phase:

          F1 = (F X V) + [0.1 X B X (T - V)]
               -----------------------------
                            T

     Where:

     Fl   is the adjusted Vehicle Inspection Fee per Reimbursable Test to the
          nearest whole cent

     F    is the base Vehicle Inspection Fee per Reimbursable Test which is
          $5.82

     V    is the monthly Base Volume of Tests which is 175,000

     B    is the Operating Cost Component of the Vehicle Inspection Fee which is
          $5.22.  The product of 0.1 multiplied by B will be rounded to the
          nearest whole cent

     T    is the number of Reimbursable Tests in the month.

                               AMENDMENT NUMBER 4 TO
                              AGENCY SERVICE AGREEMENT

     In consideration of the execution of the Professional Services Agreement
Number VI-8302, executed May 19, 1997 (hereinafter, "Enhanced I/M Agreement"),
between the Illinois Environmental Protection Agency (hereinafter, "Agency") and
Envirotest Illinois, Inc. (hereinafter, "Contractor"), whose address is 246
Sobrante Way, Sunnyvale, CA 94086, the parties hereto further agree as follows:

                                     WITNESSETH:

     WHEREAS, the Agency and the Contractor entered into the Enhanced I/M
Agreement hereinabove described, pursuant to which the Agency engaged the
Contractor to perform services in connection with the Illinois Vehicle Emissions
Inspection Law of 1995;

     WHEREAS, the Enhanced I/M Agreement incorporates the Scope of Services for
the Extension of the Vehicle Emission Test Program, dated October 31, 1990
(hereinafter, "Scope"), the License Agreement, dated October 31, 1990, the
Contractor's Technical Proposal, dated September 21, 1990, and each of seven (7)
Amendments subsequently entered into pursuant to the terms of the Agreement
(collectively contained in Appendix 10.20 of the Enhanced I/M Agreement and
hereinafter referred to as the "Basic I/M Agreement");

     WHEREAS, the Parties are desirous of clarifying the requirement to provide
updated system documentation in conjunction with the implementation of each
future Engineering Modification Request ("EMR") as described in Paragraph 9 of
Amendment Number 6 to the Basic I/M Agreement (contained in Appendix 10.20 of
the Enhanced I/M Agreement);

     WHEREAS, to reflect the further understandings and agreement of the Agency
and the Contractor, the Agency and the Contractor have determined it to be in
their best interests to enter into this Amendment Number 4 to the Enhanced I/M
Agreement;

NOW THEREFORE, in consideration of the mutual promises contained herein, the
parties hereto agree as follows:

1.   Henceforth, all future EMR requests, as anticipated in Paragraph 9 of
     Amendment 6 of the Basic I/M Agreement, shall only be initiated by either
     the Agency Program Manager or the Contractor General Manager.  EMR requests
     shall be submitted in writing.  At a minimum, the EMR shall consist of a
     clear and concise description of the system change proposed, the
     initiator's basis for the change and shall specify the program benefits to
     be achieved by the proposed change.  Each EMR request shall also include an
     identification of updated system documentation that the initiating party
     believes should be prepared and incorporated into the system documentation
     set.  The updating of system documentation may be accomplished solely by
     change page updates.  If both the system change and the identification of
     updated system documentation is mutually agreed upon, then the


<PAGE>

     Contractor shall implement the system change within 90 days after the date
     the EMR request is mutually agreed upon (unless alternate schedules are
     agreed to) and shall update the agreed system documentation within 60 days
     after the date the EMR request is mutually agreed upon (unless alternate
     schedules are agreed to).

     If, however, the Agency and Contractor cannot agree upon all of the system
     documents to be updated as a result of the system change, but the system
     change itself and minimal system documentation updates are mutually agreed
     upon, the Contractor shall proceed to implement the system change within 90
     days after the date of such agreement and provide the Agency with these
     mutually agreed upon updates to system documentation within 60 days after
     acceptance of the EMR requests.

     For those system documents which the Agency and the Contractor disagree
     need to be updated, this disagreement shall be deemed a dispute, and shall
     be resolved utilizing the dispute resolution process of Section 6.10 of the
     Scope of Services portion of Appendix 10.20 of the Enhanced I/M Contract.

                              AGENCY SERVICE AGREEMENT


     In consideration of the execution of the Professional Services Agreement
Number VI-8302, executed May 19, 1997 (hereinafter, "Enhanced I/M Agreement")
between the Illinois Environmental Protection Agency (hereinafter, "Agency") and
Envirotest Illinois, Inc., (hereinafter, "Contractor"), whose address is 246
Sobrante Way, Sunnyvale, CA 94086, the parties hereto further agree as follows:

                                    WITNESSETH:

     WHEREAS, the Agency and the Contractor entered into the Enhanced I/M
Agreement hereinabove described, pursuant to which the Agency engaged the
Contractor to perform services in connection with the Illinois Vehicle Emissions
Inspection Law of 1995; 

     WHEREAS, the Parties recognize that certain provisions in the Enhanced I/M
Agreement concerning disbursement of Congestion Mitigation and Air Quality
("CMAQ") funds need to be modified to accurately reflect all current
requirements necessary for the proper disbursement of such funds;

     WHEREAS, advancements in technology and design improvements have, in many
instances, provided the Contractor an opportunity to substitute either
different, equivalent equipment, or newer, better equipment for the equipment
originally specified in the Contractor's Four Year New Vehicle Exemption
Technical Proposal;

     WHEREAS, to reflect the further understandings and agreement of the 
Agency and the Contractor, the Agency and the Contractor have determined it 
to be in their best interests to enter into this Amendment Number 6 to the 
Enhanced I/M Agreement;

NOW THEREFORE, in consideration of the mutual promises contained herein, the
parties hereto agree as follows:

1.   Section 8.3.7.1. of the RFP Portion of the Enhanced I/M Agreement is
     replaced with the following:

     8.3.7.1  TEST SYSTEM PAYMENTS

     The Contractor shall be paid by the State for costs incurred in
     constructing and equipping the Test System for an amount not to exceed $48
     million of CMAQ funds on a 100 percent reimbursement basis for expenditures
     made for buildings and equipment as specified in the Contractor's Technical
     Proposal.  Reimbursement shall be made, not more often than monthly, based
     upon a written Contractor Certification of the actual construction of test
     facilities completed to date and the purchase of equipment and furnishings
     as validated by the State.  The Contractor Certification shall identify the
     work 


<PAGE>

     completed and the amount owed the Contractor and shall be supported by the
     reports as required by Section 6.1.4.  Test System costs to be reimbursed
     through the use of CMAQ funds shall include the new buildings (including
     materials and building costs, architectural and engineering fees, site
     improvement costs and test contractor oversight fee) and equipment as
     specified in the Contractor's Technical Proposal.

2.   Amendment 5 to the Enhanced I/M Agreement is replaced in its entirety with
     the following:

     The Contractor may propose, and the Agency may approve, the substitution of
     certain equipment originally specified to be provided by the Contractor in
     its Four Year New Vehicle Exemption Technical Proposal, as follows:

          A)   if the originally specified equipment is unavailable, the
               proposed substitution(s) must be equal to or better than the
               equipment originally specified in performance, quality, material,
               and workmanship; and

          B)   if the originally specified equipment is currently available, the
               proposed substitution(s) must be better than the equipment
               originally specified in performance, quality, material, and
               workmanship.

3.   The Contractor's Emission Lane Computer described in Section 4.3.7.4 of the
     Technical Proposal will provide Windows 95 operating system software and
     14" monochrome monitors with associated video adapter cards in lieu of
     Windows NT operating system software and 15" color monitors.  In addition,
     the Contractor will substitute Windows 95 operating system software for
     Windows NT operating system software specified for all other PCs required
     to be provided by the Contractor in accordance with the Enhanced I/M
     Agreement.  The Contractor also agrees to reduce the amount it will seek to
     be reimbursed under Section 8.3.7.1 of the RFP Portion of the Enhanced I/M
     Agreement for the cost difference between the originally proposed
     equipment, operating system software, and customized software, and the
     replacement equipment and operating system software described hereinabove
     (such amount being agreed to as $245,000), and it shall not make any other
     claim under the Enhanced I/M Agreement for these funds.

4.   Except as hereinabove amended, the Enhanced I/M Agreement as originally
     executed and heretofore amended shall remain in full force and effect.

             (The remainder of this page is intentionally left blank).

application forms for temporary extensions and annual exemptions.  The
Contractor shall keep an accurate count of the number of citizens waiting for
items such as the processing of applications for temporary extensions and annual
exemptions during each fifteen minute period.  If the Contractor does not
process each application and decide whether to issue a certificate of temporary
extension or annual exemption with no more than a fifteen minute wait for each
motorist who comes to an inspection station to apply for a temporary extension
or annual exemption, the Contractor shall report to the State what actions the
Contractor will take to process these applications with no 


                                         -3-

<PAGE>

more than a fifteen minute wait for each motorist. If, within ninety (90) days
after taking these actions, the Contractor still is failing to process these
applications with no more than a fifteen (15) minute wait for each motorist, the
Contractor and State shall mutually determine what additional actions need to be
taken to reduce the waiting time for applicants to below fifteen minutes.

     3.   Section I of the General Conditions of the contact is amended by
adding a paragraph number 24, Closing of Inspection Stations, at the end of the
section to state:

     The contractor is authorized to close the vehicle emission testing stations

     testing station, the Contractor shall remove from the station property all
     signs that identify it as a vehicle emission testing station and shall
     place prominently at the station a sign that informs motorists where their
     vehicles may be tested, including locations of nearby testing stations and
     their hours of operation.  Contractor shall make it a condition of sale of
     all former stations that subsequent owners shall maintain the sign until
     the station building is removed.  Upon closing each testing station,
     Contractor shall also remove all roadway/highway signs providing directions
     to the station being closed.

     4.   The parties further agree as a term of this Amendment Four that:

     Contractor has alleged that the 1995 Legislation constitutes a breach of
this Contract. The State denies that there has been any breach of this Contract
by the State as a consequence of changes required by the 1995 Legislation.  The
Contractor and State agree that neither shall assert, offer or otherwise use
this Amendment Four in any way in any forum, including legislative or judicial
proceedings, as evidence of a breach of an admission of a breach of this
Contract by the State, or as evidence of an admission by the Contractor of an
absence of breach by the State.

               AMENDMENT NUMBER FIVE TO THE GENERAL CONDITIONS OF THE
               CONTRACT FOR THE ESTABLISHMENT AND OPERATION OF MOTOR
                  VEHICLE INSPECTION/MAINTENANCE PROGRAM FOR THE 
                    STATE OF MINNESOTA POLLUTION CONTROL AGENCY


     This Amendment Number Five is made to the Contract entered into between the
State of Minnesota, acting through its Pollution Control Agency, hereafter
referred to as the "State," and Envirotest Technologies, Inc., doing business in
Minnesota as Envirotest Technologies, Inc., hereafter referred to as the
"Contractor." Additions are underlined; deletions are shown in over-strike type.

     WHEREAS, the State and the Contractor entered into the Contract on July 18,
1990, for the design, construction, equipment, establishment, maintenance and
operation of public inspection stations for the motor vehicle inspection and
maintenance program for the Twin Cities Metropolitan Area, hereafter referred to
as the "I/M Program;"

     WHEREAS, the Contract required the Contractor to construct and operate
eleven vehicle emission testing stations at locations throughout the Twin Cities
Metropolitan Area;

     WHEREAS, the Contract has been amended four times, on June 17, 1991, May
15, 1992, September 30, 1993, and September 6, 1995, and as amended is in effect
today;

     WHEREAS, the statute governing the I/M Program, Minn. Stat. Sections 116.60
- - .65, was amended by the 1995 Minnesota Legislature in 1995 Minn. Laws ch. 204,
hereafter referred to as the "1995 Legislation";

     WHEREAS, the 1995 Legislation exempts newer vehicles from vehicle emission
testing;

     WHEREAS, the Contractor wishes to reduce some of the services required by
the Contract, increase the portion of the testing fee that it is paid and
undertake other revenue-producing activities at the vehicle emission testing
stations, in light of the reduced number of vehicles to be tested;


<PAGE>

     WHEREAS, the Contractor and State agree that the changes to the Contract
made in this amendment will not cause excessive wait times and public
inconvenience for citizens required to test their vehicles; and

     WHEREAS, the Contractor and State agree that the additional compensation
given to the Contractor in this amendment shall not exceed the funds, minus
State administrative costs, appropriated from the Vehicle Emission Inspection
Account established in Minn. Stat. Section 116.65.

     NOW THEREFORE, the State and Contractor agree to amend the July 18, 1990
Contract as follows:

     1.   Section I.23.d, Temporary Extensions and Annual Exemptions, Hotline,
of the General Conditions of the Contract, is amended to read as follows:

          d.   HOTLINE.  The Contractor shall have a minimum of five (5)
full-time equivalent personnel providing hotline telephone service.  One
full-time employee of the Contractor's Minnesota headquarters staff shall
supervise the hotline telephone service. The Contractor shall staff the hotline
for forty-five (45) hours per week from Monday through Friday, including
adequate coverage for peak periods of calling.  The Contractor shall adequately
handle 1400 calls per day during the busiest days of the month, and 200 calls
per hour during the busiest hours of the month.

     2.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 25, Rulemaking, at the end of the Section to state:

     As soon as reasonably practicable, the Minnesota Pollution Control Agency
     (MPCA) staff will prepare and present to the MPCA Board a request to
     initiate rulemaking on a proposed amendment to Minn. R. 7023.1105, subp.
     2(A) that makes the inspection fee cover the initial inspection and one
     reinspection.  The MPCA staff will use their best 


                                         -2-

<PAGE>

     efforts to encourage this rule amendment to be adopted by the MPCA Board. 
     The Contractor understands and agrees that whether such a rule proceeding
     is initiated and whether such a rule amendment is adopted rest fully in the
     discretion of the MPCA Board, and must be based upon the record of the rule
     proceeding.   For the purposes of this paragraph, the Commissioner is
     considered a member of the MPCA Board, not the MPCA staff.

     3.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 26, Printing of Vehicle Inspection Reports, at the end
of the Section to state:

     The State will print the Vehicle Instruction Report forms.

     4.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 27, One Day Temporary Registrations, at the end of the
Section to state:

     The Contractor shall administer the one day temporary registration process
as follows:

          a.   At the vehicle emission testing station, the station manager or
     lead lane inspector shall handle requests for one day temporary
     registrations.  The Contractor's staff at the Contractor's headquarters
     office shall also handle requests for one day temporary registrations.

          b.   When a person requests a one day temporary registration, the
     Contractor must ask for the vehicle's license number and carefully review
     the SISM records to verify that the vehicle has not already been tested. If
     the vehicle owner qualifies for a temporary extension, the Contractor must
     grant one. The one day temporary registration is an additional option for
     vehicle owners, but does not replace the temporary extension.

          c.   If the vehicle owner does not qualify for a temporary extension
     and if the vehicle's registration has expired, or will expire shortly, the
     Contractor must offer the vehicle owner a one day temporary registration. 
     The vehicle owner may receive a one day temporary registration even if the
     vehicle owner has not complied with a previous temporary extension.


                                         -3-

<PAGE>

          d.   The Contractor shall not require an application for a one day
     temporary registration.  The one day temporary registration must be on a
     form approved in writing by the State and clearly state that it does not
     allow the vehicle owner to purchase vehicle license tabs.

          e.   The Contractor may issue a one day temporary registration only to
     the registered owner of the vehicle, unless the registered owner is not
     available. If the registered owner is not available, the Contractor may
     issue a one day temporary registration to a person who is a spouse, parent
     or adult child of, or who holds a power of attorney for, the registered
     owner.

          f.   The contractor must issue one day temporary registrations using a
     procedure approved in writing by the State. The currently approved
     procedure is attached to this Amendment Five as Attachment G of the General
     Conditions, and it is incorporated by reference herein and made an integral
     and enforceable part of this Contract.

          g.   Any changes to the procedure or form must be approved in writing
     by the State prior to the Contractor implementing them.

     5.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 28, Other Revenue-Producing Activities, at the end of
the Section to state: 

          The Contractor may use some or all of the vehicle emission testing
     stations for the sale and delivery of goods and services or other
     revenue-producing activities if the Contractor requests and obtains the
     prior written approval of the State for each kind of sale, service, or
     other revenue-producing activity.  Any Contractor's request under this
     paragraph must be in writing, and must contain the Contractor's analysis of
     the effect of the activity on the length of the queue, wait times,
     throughput and customer service at the station(s) where the activity will
     occur, and on the Contractor's ability to carry out all other obligations
     under this Contract. The State's approval shall not be unreasonably
     withheld. The State may, however, reject or modify any proposed sale,
     service, or other revenue-producing activity if it finds the proposal
     likely to significantly adversely affect the length of 


                                         -4-

<PAGE>

     the queue, wait times, throughput, customer service or the Contractor's
     ability to carry out all other obligations under this Contract, at any
     individual testing station or on the testing network as a whole, to
     constitute a conflict of interest under Section VI.E. or to be
     inappropriate in light of public expectations of a government service
     facility. The State shall review a request under this paragraph and provide
     the Contractor with its written approval, approval conditional on
     modification, or rejection within forty-five (45) days of the State's
     receipt of the request.  Any sale, service or other revenue-producing
     activity carried out by the Contractor under this paragraph is at the
     Contractor's own risk, and capital costs and other expenditures related
     thereto are not eligible for compensation under Section IX.C.

          The State may terminate, upon sixty (60) days prior written notice,
     the Contractor's approval to carry out a sale, service or other
     revenue-producing activity at any time the State finds that the Contractor
     is not carrying out the activity in compliance with the State's approval or
     approval conditioned on modification; that the activity causes or
     contributes to a violation of the contract on the length of the queue, wait
     times, throughput, customer service or of any of the Contractor's other
     obligations under this Contract, at any individual testing station or on
     the testing network as a whole; or that the activity constitutes a conflict
     of interest under Section VI.E or is inappropriate in light of public
     expectations of a government service facility.  The State agrees to not
     unreasonably terminate an approved activity and to meet informally with the
     Contractor to discuss the State's concerns about an activity before the
     State sends its written notice terminating approval of an activity.

          In the event that the Contractor makes a request of or claim against
     the State for any additional compensation, including a request under
     Section IX.C., the Contractor shall submit within thirty (30) days of the
     State's written request, a report to the State on all activities conducted
     under the previous paragraphs, including: the Contractor's revenues,
     capital costs and other expenditures and profits on each activity, the
     Contractor's evaluation of the impact of each activity on the length of the
     queue, wait times, throughput, 


                                         -5-

<PAGE>

     and customer service, and the Contractor's ability to carry out all other
     obligations under this Contract.

     6.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 29, Lane Deactivation, at the end of the Section to
state:

          The Contractor may deactivate specific lanes at some or all of the
     vehicle emission testing stations if the Contractor requests and obtains
     the prior written approval of the State for each lane deactivated. Any
     Contractor's request for lane deactivation must not be made before the
     Contractor has submitted the report required by Section I.31.  Amendment
     Four Report, must be in writing, and must contain the Contractor's analysis
     of the effect of deactivating each lane on the length of the queue, wait
     times, throughput and customer service at the station(s) where lanes would
     be deactivated, and the Contractor's ability to carry out all other
     obligations under this Contract.  The State's approval shall not be
     unreasonably withheld.  The State may, however, reject or modify any
     proposed lane deactivation if it finds that the lane deactivation is likely
     to significantly adversely affect the length of the queue, wait times,
     throughput, customer service, or the Contractor's ability to carry out all
     other obligations under this Contract, at any individual testing station or
     on the testing network as a whole.  The State shall review a request under
     this paragraph and provide the Contractor with its written approval,
     approval conditioned on modification, or rejection within forty-five (45)
     days of the State's receipt of the request.

          If the State determines that an approved lane deactivation causes or
     contributes to a violation of the contract requirements on the length of
     the queue, wait times throughput, customer service, or of any of the
     Contractor's other obligations under this Contract, at any individual
     testing station or on the testing network as a whole, the State may
     terminate, upon sixty (60) days prior written notice, the Contractor's
     approval to deactivate a lane.  The State agrees to not unreasonably
     terminate an approved lane deactivation and to meet informally with the
     Contractor to discuss the State's concerns about lane deactivation before
     the State sends its written notice terminating approval of the lane
     deactivation.


                                         -6-

<PAGE>

     7.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 30, Minnesota Headquarters Staff, at the end of the
Section to state:

     The Contractor may decrease the staff in its Minnesota headquarters office
(headquarters office) required under this Contract, provided that any reduction
does not significantly adversely affect customer service, the Contractor's
ability to provide appropriate headquarters office support for operations at the
vehicle emission testing stations, and the Contractor's ability to carry out all
other obligations under this Contract.  The Contractor shall notify the State in
writing of the reduction no later than the time the Contractor announces the
changes to its headquarters office staff.  The Contractor's notification shall
include an organization chart of the headquarters office staff that shows the
functions of managerial personnel.

     8.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 31, Amendment Four Report, at the end of the Section
to state:

     By January 20, 1996, the Contractor shall provide the State with the
Contractor's analysis of the effect of the changes authorized in Amendment Four
on the length of the queue, wait times, throughput and customer service and the
Contractor's ability to carry out all other obligations under this Contract, at
each testing station and on the network as a whole.  The State shall review this
report and provide the Contractor with its written approval, approval
conditioned on modification, or rejection within forty-five (45) days of the
State's receipt of the report.

     9.   Section I of the General Conditions of the Contract is amended by
adding a paragraph number 32, Organization of Minnesota Operations, at the end
of the Section to state:

     By November 15, 1995, Contractor shall submit to the State an updated
organization chart of its Minnesota headquarters and testing station staff that
shows the organizational structure and number of staff assigned to each function
over the testing network.  The proposed organization or staffing levels must not
significantly adversely 


                                         -7-

<PAGE>

affect the Contractor's ability to provide appropriate headquarters office
support for operations at the vehicle emission testing stations.  Contractor's
ability to properly supervise and conduct operations at the vehicle emission
testing stations, or the Contractor's ability to carry out all other obligations
under this Contract, at any individual testing station or on the testing network
as a whole.

     10.  Section II.A., Consideration of the-General Conditions of the
Contract is amended to read as follows:

     The State shall pay the Contractor, until November 1, 1995, for all 
activities conducted pursuant to this contract, $7.07 for each fee bearing 
inspection, each fee bearing reinspection and each fee bearing elective 
inspection performed on or after the Extension/Exemption Startup Date and for 
which the State has been paid by the citizen who obtained the inspection.  On 
and after November 1, 1995, and until June 30, 1996, the State shall pay the 
Contractor, for all activities conducted pursuant to this contract, $8.00 for 
each fee bearing inspection, each fee bearing reinspection, and each fee 
bearing elective inspection performed by the Contractor and for which the 
State has been paid by the citizen who obtained the inspection.  After June 
30, 1996, and until June 30, 1997, the State shall pay the Contractor, for all 
activities conducted pursuant to this contract, $7.28 for each fee bearing 
inspection, each fee bearing reinspection and each fee bearing elective 
inspection performed by the Contractor and for which the State has been paid 
by the citizen who obtained the inspection.  After June 30, 1997 and until 
June 30, 1998, the State shall pay the Contractor, for all activities 
conducted pursuant to this contract, a To-Be-Determined Amount ("TBDA") for 
each fee bearing inspection, each fee bearing reinspection and each fee 
bearing elective inspection performed by the Contractor and for which the 
State has been paid by the citizen who obtained the inspection.  The State, on 
the effective date of Amendment Five, estimates that the TBDA will be 
approximately $7.00, but the exact amount of the TBDA shall be determined as 
provided by the following sentence.  The TBDA shall not exceed $8.00 and shall 
be determined by the 

                                         -8-

<PAGE>

State after review of testing revenues and the vehicle emission inspection
account balance through June 30, 1997, and projected revenues and MPCA and
Department administrative costs through the end of all State and Contractor
activities under the I/M Program, so that the amount of revenues allocated for
the year beginning July 1, 1997 to the Contractor through the TBDA will assure
that all MPCA and Department administrative costs plus a contingency of $15,000
are allowed for in the vehicle emission inspection account.  The TBDA shall be
determined by the State by August 15, 1997.  These fees are, in the event of
termination of the I/M Program by legislation prior to June 30, 1998, subject to
adjustment as provided in the next paragraph, and are the Contractor's sole
compensation for all activities conducted pursuant to this contract, except as
may be provided in Section IX.C.

     If the legislature terminates the I/M Program prior to June 30, 1998, and
the Contractor has received more than an average of $7.35, between July 1, 1995,
and the date testing ends, per fee bearing inspection, fee bearing reinspection
and fee bearing elective performed by the Contractor, and for which the State
has been paid by the citizen who obtained the inspection, then the amounts
specified in the preceding paragraph due the Contractor will be reduced by the
State, and as necessary reimbursed to the State by the Contractor (except as may
be provided in Section IX.C.) within sixty (60) days of the State's written
request, so that by the end of testing the Contractor will have been provided
with an average of $7.35 per fee bearing inspection, fee bearing reinspection
and fee bearing elective inspection performed by the Contractor, and for which
the State has been paid by the citizen who obtained the inspection, between July
1, 1995, and the date testing ends.

     A fee-bearing inspection is the initial inspection and, if the vehicle
fails the initial inspection, the number of reinspections of a subject vehicle
during one annual registration period covered by the initial fee assessed
pursuant to Minn. Rules pt. 7023.1105, subp. 2(A).  A fee bearing reinspection
is 


                                         -9-

<PAGE>

each subsequent reinspection of a subject vehicle during one annual registration
period for which an additional fee is assessed under Minn. Rules pt. 7023.1105,
subp. 2(A).  A fee bearing elective inspection is any single inspection of a
subject or nonsubject vehicle approved in advance by the State and conducted
pursuant to Minn.  Rules pt. 7023.1105, subp. 2(B).  The State agrees that,
pursuant to Minn.  Rules pt. 7023.1105, it will set the inspection fee at an
amount not less than the amounts specified in the first paragraph, and that if
its administrative costs exceed the difference between the inspection fee
collected from citizens and the amounts specified in the first paragraph due the
Contractor, the excess State administrative costs will not reduce the amount
paid to the Contractor under Section II.

     The State shall not pay the Contractor for inspections conducted by the
Contractor for which the State has not been paid by the citizen who obtained the
inspection.  The State shall not pay the Contractor for inspections conducted
before the network startup date.

     The total obligation of the State for all compensation and reimbursements
to Contractor shall not exceed the funds appropriated to the I/M Program in the
vehicle emission inspection account.  Minn.  Stat. Section 116.65, subd. 1
establishes a vehicle emission inspection account which consists of the revenues
listed in Minn.  Stat. Section 116.65, subd. 2, including the proceeds of the
vehicle inspection fee.  Minn. Stat. Section 116.65 provides that the vehicle
emission inspection account is appropriated to the Agency by the legislature,
and may be used only to pay the Contractor for vehicles inspected and MPCA and
Department administrative costs for the I/M Program.  The Contractor understands
and agrees, however, that the vehicle emission inspection account will not
contain substantial funds until the commencement of vehicle inspection and the
collection of fees from motorists for vehicle inspection, and that the vehicle
emission inspection account will be regularly depleted after that point to pay
the Contractor for vehicles inspected and to pay State administrative costs to
conduct the I/M Program.  Contractor also understands and 


                                         -10-

<PAGE>

agrees that, in the unlikely event that the legislature ceases to appropriate
funds for the I/M Program, the legislature may not authorize sufficient funds to
pay the Contractor's costs.

     11.  Section VII. E., Performance Bond, of the General Conditions of the
Contract is amended to read as follows:

     The Contractor has filed with the State's Authorized Agent a performance
bond on the forms included in Attachment B to these General Conditions, which is
attached, incorporated by reference herein, and made an integral and enforceable
part of this contract, in the amount of $1,000,000 as security for the faithful
performance of the contract.  The Contractor shall provide a performance bond or
a series of performance bonds that shall remain in full force and effect, under
the same terms and conditions as Attachment B, during the entire term of this
contract, except that after the effective date of Amendment Five, the amount of
the performance bond may be reduced to $100,000.  The surety furnishing the
performance bond shall be licensed to conduct business in the State of
Minnesota.  The initial performance bond shall be for a four (4) year term, and
the Contractor shall renew the bond, on the same terms and conditions, for an
additional four (4) year term commencing the day after expiration of the initial
performance bond, and submit the performance bond to the MPCA for approval at
least sixty (60) days prior to expiration of the initial performance bond.  The
Contractor's obligation to deliver a renewed performance bond shall not be an
obligation secured by the initial performance bond.

     The attorney-in-fact who executes the performance bond on behalf of the
surety must attach a notarized copy of its power of attorney as evidence of its
authority to bind the surety on the date of execution of the performance bond.

     12.  The parties further agree as a term of this Amendment Five that:

     Contractor has alleged that the 1995 Legislation constitutes a breach of
this Contract.  The State denies that there has been any breach of this Contract
by the State as 


                                         -11-

<PAGE>

a consequence of changes required by the 1995 Legislation.  In consideration for
the State's entering into this Amendment Five, the Contractor waives any and all
claims or causes of action, in law or equity, it may have against the State
resulting from the 1995 Legislation.  This waiver shall not be effective if the
legislature terminates the I/M Program before June 30, 1998 or if the
legislature makes changes to the I/M Program the result of which is a further
reduction in vehicles subject to fee bearing inspections between the effective
date of this Amendment Five and June 30, 1998. Contractor's waiver does not
prevent the Contractor from requesting additional appropriations from the
legislature.

     13. This Amendment Five is effective when it is signed by the Commissioner
of Administration.


                                         -12-

     14.  All other terms and conditions of the Contract remain in full force
and effect, except as specifically amended above.

      5. Incentive Compensation Program.

      The Executive shall participate in an incentive compensation program (the
"Incentive Compensation Program"). There shall be no minimum or guaranteed
amount of compensation payable to the Executive under the Incentive Compensation
Program. Payments to the Executive pursuant to the Incentive Compensation
Program ("Incentive Compensation Payments") shall be based on business
performance objectives to be agreed between the Executive and the Company, and
the maximum amount of aggregate annual Incentive Compensation Payments shall be
fifty percent (50%) of the Executive's annual salary, as the same may be
adjusted from time to time. For exceptional performance by the Executive, the
Company may, in its sole discretion, grant to the Executive options with respect

Executive no later than two and one-half months following the close of the

      6. Stock Options.

      The Executive shall be entitled to receive nonqualified stock options for

the date of grant. The stock option agreement shall provide that the option
shall vest at the rate of thirty-three and one-third percent (33 1/3%) on each

vested on the third anniversary date of the Executive's employment under this
Agreement, provided, however, that the option shall become fully vested on the
date on which the registration statement for initial public offering of the
common stock of the Company is declared effective by the Securities and Exchange
Commission. The stock option shall provide that it may be exercised for ten (10)
years from the date of grant, unless earlier terminated. The vested portion 
of the option may be exercised within two (2) years following the Executive's 
termination of employment to the extent vested.  The 


                                       3


<PAGE>

unvested portion of the option shall expire upon the Executive's termination of
employment. The stock option also shall provide that the option shall become
fully vested and exercisable in the event of the Executive's death, disability,

Change of Control. For purposes of this Agreement and the related option, a
"Change of Control" shall mean any of the following events:

or the Company, other than a reorganization that does not affect the beneficial
ownership of Newmall or the Company; and

liquidation or dissolution.

      The sale of fifty percent (50%) or more of the common stock of the Company
in an initial public offering shall not constitute a Change in Control. The
stock option shall be set forth in a written agreement and shall be subject to
such additional terms as may be contained in such agreement that are not
inconsistent with this Section 6. The Company has advised the Executive that it
intends to file a registration statement on 


                                       4

Executive's duties under this Agreement (with the prior written approval of the

      limitations set forth below with respect to the maximum amount of
      Revolving Loans permitted to be outstanding from time to time, to lend to
      the Company from time to time during the period from the Closing Date to
      but excluding the Revolving Loan Commitment Termination Date an aggregate
      amount not exceeding its Pro Rata Share of the aggregate amount of the
      Revolving Loan Commitments, to be used for the purposes identified in
      subsection 2.5A or B, as applicable, including, without limitation, the
      Initial Revolving Loans on the Closing Date. The original amount of each

      Revolving Loans and all other amounts owed hereunder with respect to the
      Revolving Loans and the Revolving Loan Commitments shall be paid in full
      no later than that date. Amounts borrowed under this subsection 2.1A(iii)

            Notwithstanding anything contained herein to the contrary, in no

            (iv) Swing Line Loans. The Swing Line Lender hereby agrees, subject
      to the limitations set forth below with respect to the maximum aggregate
      amount of all Swing Line Loans outstanding from time to time, to make a

      Revolving Loan Commitment Termination Date by making Base Rate Loans as
      Swing Line Loans to the Company in an aggregate amount not to exceed the
      amount of the Swing Line Loan Commitment, to be used for the purposes
      identified in subsection 2.5B, notwithstanding the fact that such Swing
      Line Loans, when aggregated with the sum of the Swing Line Lender's
      outstanding Revolving Loans and the Swing Line Lender's Pro Rata Share of

      Loan Commitment are subject to reduction as provided in clause (b) of the

      Revolving Loan Commitment Termination Date.

            Notwithstanding anything contained herein to the contrary, the Swing
      Line Loans and the Swing Line Loan Commitment shall be subject to the
      following limitations:

                  (a) in no event shall the Total Utilization of Revolving Loan
            Commitments at any time exceed the Revolving Loan Commitments then
            in effect;

                  (b) any reduction of the Revolving Loan Commitments made
            pursuant to subsection 2.4B which reduces the aggregate Revolving
            Loan Commitments to an amount less than the then current amount of
            the Swing Line Loan Commitment shall result in an 


                                       41

<PAGE>

            automatic corresponding reduction of the Swing Line Loan Commitment
            such that the amount thereof equals the amount of the Revolving Loan
            Commitments, as so reduced, without any further action on the part
            of the Company, the Administrative Agent or the Swing Line Lender;
            and

                  (c) the Swing Line Lender shall have no obligation to make any
            Swing Line Loans during any period when a Lender Default exists,
            unless the Swing Line Lender has entered into arrangements
            satisfactory to it and the Company to eliminate the Swing Line
            Lender's risk with respect to the Defaulting Lender, including by
            cash collateralizing such Defaulting Lender's Pro Rata Share of the
            Revolving Loans that may be required to be made to refund the
            applicable Swing Line Loan as contemplated by the immediately
            following paragraph.

            With respect to any Swing Line Loans which have not been voluntarily
      prepaid by the Company pursuant to subsection 2.4B(i), the Swing Line
      Lender may, at any time in its sole and absolute discretion, deliver to
      the Administrative Agent (with a copy to the Company), no later than 11:00
      a.m. (New York time) at least one (1) Business Day in advance of the
      proposed Funding Date, a notice (which shall be deemed to be a Notice of
      Borrowing given by the Company) requesting the Lenders to make Revolving
      Loans that are Base Rate Loans to the Company on such Funding Date in an
      amount equal to the amount of such Swing Line Loans (the "Refunded Swing
      Line Loans") outstanding on the date such notice is given which the Swing
      Line Lender requests the Lenders to prepay. Anything contained in this
      Agreement to the contrary notwithstanding, (i) the proceeds of such
      Revolving Loans made by the Lenders other than the Swing Line Lender shall
      be immediately delivered by the Administrative Agent to the Swing Line
      Lender (and not to the Company) and applied to repay a corresponding
      portion of the Refunded Swing Line Loans and (ii) on the day such
      Revolving Loans are made, the Swing Line Lender's Pro Rata Share of the
      Refunded Swing Line Loans shall be deemed to be paid with the proceeds of
      a Revolving Loan made by the Swing Line Lender to the Company, and such
      portion of the Swing Line Loans deemed to be so paid shall no longer be
      outstanding as Swing Line Loans and shall no longer be due under the Swing
      Line Note of the Swing Line Lender but shall instead constitute part of
      the Swing Line Lender's outstanding Revolving Loans to the Company and
      shall be due under the Revolving Note issued by the Company to the Swing
      Line Lender. The Company hereby authorizes the Administrative Agent and
      the Swing Line Lender to charge the Company's accounts with the
      Administrative Agent and the Swing Line Lender (up to the amount available
      in each such account) in order to immediately pay the Swing Line Lender
      the amount of the Refunded Swing Line Loans to the extent the proceeds of
      such Revolving Loans made by the Lenders, including the Revolving Loan
      deemed to be made by the Swing Line Lender, are not sufficient to repay in
      full the Refunded Swing Line Loans. If any portion of any such amount paid
      (or deemed to be paid) to the Swing Line Lender should be recovered by or
      on behalf of the Company from the Swing Line Lender in bankruptcy, by
      assignment for the benefit of creditors or otherwise, the loss of the
      amount so recovered shall be ratably shared among all Lenders in the
      manner contemplated by subsection 10.5.

            If for any reason Revolving Loans are not made pursuant to this
      subsection 2.1A(iv) in an amount sufficient to repay any amounts owed to
      the Swing Line Lender in respect of any outstanding Swing Line Loans on or
      before the third (3rd) Business Day after demand for payment thereof by
      the Swing Line Lender, each Lender shall be deemed to, and hereby agrees
      to, have purchased a participation in such outstanding Swing Line Loans,
      and in an amount equal to its Pro 


                                       42

<PAGE>

      Rata Share of the applicable unpaid amount together with accrued interest
      thereon. Upon one (1) Business Day's notice from the Swing Line Lender,
      each Lender shall deliver to the Swing Line Lender an amount equal to its
      respective participation in the applicable unpaid amount in same day funds
      at the office of the Swing Line Lender located at the Funding and Payment
      Office. In order to evidence such participation each Lender agrees to
      enter into a participation agreement at the request of the Swing Line
      Lender in form and substance satisfactory to the Swing Line Lender. In the
      event any Lender fails to make available to the Swing Line Lender the
      amount of such Lender's participation as provided in this paragraph, the
      Swing Line Lender shall be entitled to recover such amount on demand from
      such Lender together with interest thereon at the rate customarily used by
      the Swing Line Lender for the correction of errors among banks for three
      (3) Business Days and thereafter at the Base Rate, as applicable.

            Notwithstanding anything contained herein to the contrary, (i) each
      Lender's obligation to make Revolving Loans for the purpose of repaying
      any Refunded Swing Line Loans pursuant to the second preceding paragraph
      and each Lender's obligation to purchase a participation in any unpaid
      Swing Line Loans pursuant to the immediately preceding paragraph shall be
      absolute and unconditional and shall not be affected by any circumstance,
      including without limitation (a) any set-off, counterclaim, recoupment,
      defense or other right which such Lender may have against the Swing Line
      Lender, the Company or any other Person for any reason whatsoever; (b) the
      occurrence or continuation of a Default or Event of Default; (c) any
      adverse change in the business, operations, properties, assets, condition
      (financial or otherwise) or prospects of the Company or any of its
      Subsidiaries; (d) any breach of this Agreement or any other Loan Document
      by any party thereto; or (e) any other circumstance, happening or event
      whatsoever, whether or not similar to any of the foregoing; provided that
      such obligations of each Lender are subject to the condition that the
      Swing Line Lender believed in good faith that all conditions under Section
      4 to the making of the applicable Refunded Swing Line Loans or other
      unpaid Swing Line Loans, were satisfied at the time such Refunded Swing
      Line Loans or unpaid Swing Line Loans were made, or the satisfaction of
      any such condition not satisfied had been waived by Requisite Lenders
      prior to or at the time such Refunded Swing Line Loans or other unpaid
      Swing Line Loans were made; and (ii) the Swing Line Lender shall not be
      obligated to make any Swing Line Loans if it has elected not to do so
      after the occurrence and during the continuation of a Default or Event of
      Default.

      B. Borrowing Mechanics. Term Loans or Revolving Loans (including any such
Loans made as Eurodollar Rate Loans with a particular Interest Period) made on
any Funding Date (other than Revolving Loans made pursuant to a request by the
Swing Line Lender pursuant to subsection 2.1A(iv) for the purpose of repaying
any Refunded Swing Line Loans and Revolving Loans made pursuant to subsection
3.3B for the purpose of reimbursing the Issuing Bank for the amount of a drawing
or payment under a Letter of Credit issued by it) shall be in an aggregate
minimum amount of $2,000,000 and integral multiples of $500,000 in excess of
that amount; provided that any Eurodollar Rate Loan shall be in a minimum amount
of $2,500,000 and integral multiples of $500,000 in excess of that amount. Swing
Line Loans made on any Funding Date shall be in an aggregate minimum amount of
$500,000 and integral multiples of $100,000 in excess of that amount. Whenever
the Company desires that the Lenders make Term Loans or Revolving Loans it shall
deliver to the Administrative Agent a Notice of Borrowing no later than 11:00
a.m. (New York time), at least three (3) Business Days in advance of the
proposed Funding Date in the case of a Eurodollar Rate Loan, or at least one (1)
Business Day in advance of the proposed Funding Date in the case of a Base Rate
Loan. Whenever the Company desires that the Swing Line Lender make a Swing Line
Loan, it shall deliver to Administrative Agent a Notice of Borrowing no 


                                       43

<PAGE>

later than 11:00 a.m. (New York time) on the proposed Funding Date. The Notice
of Borrowing shall specify (i) the proposed Funding Date (which shall be a
Business Day), (ii) the amount and type of Loans requested, (iii) in the case of
Swing Line Loans and Loans made on the Closing Date, that such Loans shall be
Base Rate Loans, (iv) in the case of any Loans other than Swing Line Loans,
whether such Loans shall be Base Rate Loans or Eurodollar Rate Loans, and (v) in
the case of any Loans requested to be made as Eurodollar Rate Loans, the initial
Interest Period requested therefor. Term Loans and Revolving Loans may be
continued as or converted into Base Rate Loans and Eurodollar Rate Loans in the
manner provided in subsection 2.2D. In lieu of delivering the above-described
Notice of Borrowing, the Company may give the Administrative Agent telephonic
notice by the required time of any proposed borrowing under this subsection
2.1B; provided that such notice shall be promptly confirmed in writing by
delivery of a Notice of Borrowing to the Administrative Agent on or before the
applicable Funding Date.

      Neither the Administrative Agent nor any Lender shall incur any liability
to the Company in acting upon any telephonic notice referred to above that the
Administrative Agent believes in good faith to have been given by a duly
authorized officer or other person authorized to borrow on behalf of the Company
or for otherwise acting in good faith under this subsection 2.1B, and upon
funding of Loans by the Lenders in accordance with this Agreement pursuant to
any such telephonic notice the Company shall have effected Loans hereunder.

      The Company shall notify the Administrative Agent prior to the funding of
any Loans in the event that any of the matters to which the Company is required
to certify in the applicable Notice of Borrowing are no longer true and correct
as of the applicable Funding Date, and the acceptance by the Company of the
proceeds of any Loans shall constitute a re-certification by the Company, as of
the applicable Funding Date, as to the matters to which the Company is required
to certify in the applicable Notice of Borrowing.

      Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice
of Borrowing for a Eurodollar Rate Loan (or telephonic notice in lieu thereof)
shall be irrevocable on and after the Related Interest Rate Determination Date,
and the Company shall be bound to make a borrowing in accordance therewith.

      C. Disbursement of Funds. All Term Loans and all Revolving Loans under
this Agreement shall be made by the Lenders simultaneously and proportionately
to their respective Pro Rata Shares, it being understood that no Lender shall be
responsible for any default by any other Lender in that other Lender's
obligation to make a Loan requested hereunder nor shall the Commitment of any
Lender to make the particular type of Loan requested be increased or decreased
as a result of a default by any other Lender in that other Lender's obligation
to make a Loan requested hereunder. Promptly after receipt by the Administrative
Agent of a Notice of Borrowing pursuant to subsection 2.1B (or telephonic notice
in lieu thereof), the Administrative Agent shall notify each Lender or the Swing
Line Lender, as the case may be, of the proposed borrowing and of the amount of
such Lender's Pro Rata Share of the applicable Loans.

      Each Lender shall make the amount of its Loan available to the
Administrative Agent not later than 12:00 Noon (New York time) on the applicable
Funding Date and the Swing Line Lender shall make the amount of its Swing Line
Loan available to the Administrative Agent not later than 2:00 P.M. (New York
time) on the applicable Funding Date, in each case in same day funds, at the
Funding and Payment Office. Except as provided in subsection 2.1A(iv) or
subsection 3.3B with respect to Revolving Loans used to repay Refunded Swing
Line Loans or to reimburse the Issuing Bank for the amount of an honored drawing
or payment under a Letter of Credit issued by it, upon satisfaction or waiver of
the conditions precedent specified in subsections 4.1 (in the case of Loans made
on the Closing Date) and 4.2 (in the case of all 


                                       44
<PAGE>

Loans), the Administrative Agent shall make the proceeds of such Loans available
to the Company on the applicable Funding Date by causing an amount of same day
funds equal to the proceeds of all such Loans received by the Administrative
Agent from the Lenders or the Swing Line Lender, as the case may be, to be
credited to the account of the Company at the Funding and Payment Office.

      Unless the Administrative Agent shall have been notified by any Lender
prior to the Funding Date for any Loans that such Lender does not intend to make
available to the Administrative Agent the amount of such Lender's Loan requested
on such Funding Date, the Administrative Agent may assume that such Lender has
made such amount available to the Administrative Agent on such Funding Date and
the Administrative Agent may, in its sole discretion, but shall not be obligated
to, make available to the Company a corresponding amount on such Funding Date.
If such corresponding amount is not in fact made available to the Administrative
Agent by such Lender, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender together with interest thereon,
for each day from such Funding Date until the date such amount is paid to the
Administrative Agent, at the customary rate set by the Administrative Agent for
the correction of errors among banks for three Business Days and thereafter at
the Base Rate. If such Lender 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 immediately pay such
corresponding amount to the Administrative Agent, together with interest thereon
for each day from such Funding Date until the date such amount is paid to the
Administrative Agent at the rate applicable to such Loan. Nothing in this
subsection 2.1C shall be deemed to relieve any Lender from its obligation to
fulfill its Commitments hereunder or to prejudice any rights that the Company
may have against any Lender as a result of any default by such Lender hereunder.

      D. The Register.

            (i) The Administrative Agent shall maintain, at its address referred
      to in subsection 10.8, a register for the recordation of the names and
      addresses of the Lenders and the Commitments and Loans of each Lender from
      time to time (the "Register"). The Register shall be available for
      inspection by the Company or any Lender at any reasonable time and from
      time to time upon reasonable prior notice.

            (ii) The Administrative Agent shall record in the Register the
      Commitments and the outstanding Loans from time to time of each Lender and
      each repayment or prepayment in respect of the principal amount of the
      outstanding Loans of each Lender. Any such recordation shall be conclusive
      and binding on the Company and each Lender, absent manifest error;
      provided that failure to make any such recordation, or any error in such
      recordation, shall not affect the Company's Obligations in respect of the
      applicable Loans.

            (iii) Each Lender shall record on its internal records (including,
      without limitation, the Notes held by such Lender) the amount of each Loan
      made by it and each payment in respect thereof. Any such recordation shall
      be conclusive and binding on the Company, absent manifest error; provided
      that failure to make any such recordation, or any error in such
      recordation, shall not affect the Company's Obligations in respect of the
      applicable Loans; and provided, further that in the event of any
      inconsistency between the Register and any Lender's records, the
      recordations in the Register shall govern.

            (iv) The Company, the Administrative Agent and the Lenders shall
      deem and treat the 


                                       45

<PAGE>

      Persons listed as the Lenders in the Register as the holders and owners of
      the corresponding Commitments and Loans listed therein for all purposes
      hereof, and no assignment or transfer of any Commitment or Loan shall be
      effective, in each case unless and until an Assignment Agreement effecting
      the assignment or transfer thereof shall have been accepted by the
      Administrative Agent and recorded in the Register as provided in
      subsection 10.1B(ii). Prior to such recordation, all amounts owed with
      respect to the applicable Commitment or Loan shall be owed to the Lender
      listed in the Register as the owner thereof, and any request, authority or
      consent of any Person who, at the time of making such request or giving
      such authority or consent, is listed in the Register as a Lender shall be
      conclusive and binding on any subsequent holder, assignee or transferee of
      the corresponding Commitments or Loans.

            (v) The Company hereby designates CSFB and any financial institution
      serving as a successor Administrative Agent to serve as the Company's
      agent solely for purposes of maintaining the Register as provided in this
      subsection 2.1D, and the Company hereby agrees that, to the extent CSFB
      serves in such capacity, CSFB and its officers, directors, employees,
      agents and affiliates shall constitute Indemnitees for all purposes under
      subsection 10.3.

      E. Notes. The Company shall execute and deliver on the Closing Date to
each Lender (or to the Administrative Agent for that Lender) (i) a Term A Note
substantially in the form of Exhibit IV-A annexed hereto, respectively, to
evidence that Lender's Term A Loans in the principal amount of that Lender's
Term A Loans and with other appropriate insertions, and each Lender's Term A
Notes shall evidence such Lender's Pro Rata Share of such respective amounts,
(ii) a Term B Note substantially in the form of Exhibit IV-B annexed hereto,
respectively, to evidence that Lender's Term B Loans in the principal amount of
that Lender's Term B Loans and with other appropriate insertions, and each
Lender's Term B Notes shall evidence such Lender's Pro Rata Share of such
respective amounts, (iii) a Revolving Note substantially in the form of Exhibit
V-A annexed hereto to evidence that Lender's Revolving Loans, in the principal
amount of that Lender's Revolving Loan Commitment and with other appropriate
insertions and (iv) a Swing Line Note substantially in the form of Exhibit V-B
annexed hereto to evidence that Lender's Swing Line Loans, in the principal
amount of that Lender's Swing Line Loan Commitment and with other appropriate
insertions. The Notes and the Obligations evidenced thereby shall be governed
by, subject to and benefit from all of the terms and conditions of this
Agreement and the other Loan Documents and shall be secured by the Collateral.

2.2 Interest on the Loans.

      A. Rate of Interest. Subject to the provisions of subsections 2.6 and 2.7,
each Term Loan and each Revolving Loan shall bear interest on the unpaid
principal amount thereof from the date made to maturity (whether by acceleration
or otherwise) at a rate determined by reference to the Base Rate or the Reserve
Adjusted Eurodollar Rate, as the case may be. Subject to the provisions of
subsection 2.7, each Swing Line Loan shall bear interest on the unpaid principal
amount thereof from the date made to maturity (whether by acceleration or
otherwise) at a rate determined by reference to the Base Rate. The applicable
basis for determining the rate of interest with respect to any Loan shall be
selected by the Company initially at the time a Notice of Borrowing is given
with respect to such Loan pursuant to subsection 2.1B. The basis for determining
the interest rate with respect to any Term Loan or any Revolving Loan may be
changed from time to time pursuant to subsection 2.2D. If on any day any Term
Loan or Revolving Loan is outstanding with respect to which notice has not been
delivered to the Administrative Agent in accordance with the terms of this
Agreement specifying the applicable basis for determining the rate of interest,
then for that day that Loan shall bear interest determined by reference to the
Base Rate. Subject 


                                       46

<PAGE>

to the provisions of subsections 2.2E and 2.7, the Term Loans and the Revolving
Loans shall bear interest through maturity as follows:

                  (i) if a Base Rate Loan, then at the sum of the Base Rate plus
            the Applicable Base Rate Margin; or

                  (ii) if a Eurodollar Rate Loan, then at the sum of the Reserve
            Adjusted Eurodollar Rate plus the Applicable Eurodollar Rate Margin.

      Subject to the provisions of subsections 2.2E and 2.7, the Swing Line
Loans shall bear interest to maturity at the sum of the Base Rate plus the
Applicable Base Rate Margin for Revolving Loans less the Applicable Commitment
Fee Percentage.

      B. Interest Periods. In connection with each Eurodollar Rate Loan, the
Company may, pursuant to the applicable Notice of Borrowing or Notice of
Conversion/Continuation, as the case may be, on behalf of the Company select an
interest period (each an "Interest Period") to be applicable to such Loan, which
Interest Period shall be, at the Company's option, either a one, two, three or
six month period; provided that:

            (i) the initial Interest Period for any Eurodollar Rate Loan shall
      commence on the Funding Date in respect of such Loan, in the case of a
      Loan initially made as a Eurodollar Rate Loan, or on the date specified in
      the applicable Notice of Conversion/Continuation, in the case of a Loan
      converted to a Eurodollar Rate Loan;

            (ii) in the case of immediately successive Interest Periods
      applicable to a Eurodollar Rate Loan continued as such pursuant to a
      Notice of Conversion/Continuation, each successive Interest Period shall
      commence on the day on which the next preceding Interest Period expires;

            (iii) if an Interest Period would otherwise expire on a day that is
      not a Business Day, such Interest Period shall expire on the next
      succeeding Business Day; provided that, if any Interest Period would
      otherwise expire on a day that is not a Business Day but is a day of the
      month after which no further Business Day occurs in such month, such
      Interest Period shall expire on the next preceding Business Day;

            (iv) any Interest Period that begins on the last Business Day of a
      calendar month (or on a day for which there is no numerically
      corresponding day in the calendar month at the end of such Interest
      Period) shall, subject to clause (v) of this subsection 2.2B, end on the
      last Business Day of a calendar month;

            (v) no Interest Period with respect to any portion of the Term A
      Loans shall extend beyond March 31, 2004, no Interest Period with respect
      to any portion of the Term B Loans shall extend beyond September 30, 2005,
      and no Interest Period with respect to any portion of the Revolving Loans
      shall extend beyond the Revolving Loan Commitment Termination Date;

            (vi) no Interest Period with respect to any portion of the Term
      Loans shall extend beyond a date on which the Company is required to make
      a scheduled payment of principal of the Term A Loans or the Term B Loans,
      as the case may be, unless the aggregate principal amount of Term A Loans
      or Term B Loans, as the case may be, that are Base Rate Loans plus the
      aggregate 


                                       47

<PAGE>

      principal amount of Term A Loans or Term B Loans, as the case may be, that
      are Eurodollar Rate Loans with Interest Periods expiring on or before such
      date equals or exceeds the principal amount required to be paid on the
      Term A Loans or Term B Loans, as the case may be, on such date;

            (vii) the Company may not select an Interest Period of longer than
      one month prior to the end of the Initial Period;

            (viii) there shall be no more than five (5) Interest Period
      outstanding at any time during the Initial Period, and thereafter no more
      than ten (10) Interest Periods shall be outstanding at any time; and

            (ix) in the event the Company fails to specify an Interest Period
      for any Eurodollar Rate Loan in the applicable Notice of Borrowing or
      Notice of Conversion/Continuation, the Company shall be deemed to have
      selected an Interest Period of one month.

      C. Interest Payments. Subject to the provisions of subsection 2.2E,
interest on each Loan shall be payable in arrears on and to each Interest
Payment Date applicable to that Loan, upon any prepayment of that Loan (to the
extent accrued on the amount being prepaid) and at maturity (including final
maturity, by acceleration or otherwise); provided that in the event that any
Swing Line Loans, Revolving Loans or any Term Loans that are Base Rate Loans are
prepaid pursuant to subsection 2.4B(i), interest accrued on such Loans through
the date of such prepayment shall be payable on the next succeeding Interest
Payment Date applicable to Base Rate Loans (or, if earlier, at final maturity).

      D. Conversion or Continuation. Subject to the provisions of subsection
2.6, the Company shall have the option (i) to convert at any time all or any
part of its outstanding Term Loans or Revolving Loans equal to $2,000,000 and
integral multiples of $500,000 in excess of that amount from Loans bearing
interest at a rate determined by reference to one basis to Loans bearing
interest at a rate determined by reference to an alternative basis (provided
that any Loan being converted to a Eurodollar Rate Loan shall be in a minimum
amount of $2,500,000 and integral multiples of $500,000 in excess of such
amount) or (ii) upon the expiration of any Interest Period applicable to a
Eurodollar Rate Loan, to continue all or any portion of such Loan equal to
$2,500,000 and integral multiples of $500,000 in excess of that amount as a
Eurodollar Rate Loan; provided, however, that a Eurodollar Rate Loan may only be
converted into a Base Rate Loan on the expiration date of an Interest Period
applicable thereto.

      The Company shall deliver a Notice of Conversion/Continuation to the
Administrative Agent no later than 11:00 a.m. (New York time) at least one
Business Day in advance of the proposed conversion date (in the case of a
conversion to a Base Rate Loan), and at least three Business Days in advance of
the proposed conversion/continuation date (in the case of a conversion to, or a
continuation of, a Eurodollar Rate Loan). A Notice of Conversion/Continuation
shall specify (i) the proposed conversion/continuation date (which shall be a
Business Day), (ii) the amount and type of the Loan to be converted/continued,
(iii) the nature of the proposed conversion/continuation, (iv) in the case of a
conversion to, or a continuation of, a Eurodollar Rate Loan, the requested
Interest Period, and (v) in the case of a conversion to, or a continuation of, a
Eurodollar Rate Loan, that no Default or Event of Default has occurred and is
continuing. In lieu of delivering the above-described Notice of
Conversion/Continuation, the Company may give the Administrative Agent
telephonic notice by the required time of any proposed conversion/continuation
under this subsection 2.2D; provided that such notice shall be promptly
confirmed in writing by delivery of a Notice of Conversion/Continuation to the
Administrative Agent on or before the proposed conversion/continuation date.


                                       48

<PAGE>

      Neither the Administrative Agent nor any Lender shall incur any liability
to the Company in acting upon any telephonic notice referred to above that the
Administrative Agent believes in good faith to have been given by a duly
authorized officer or other person authorized to act on behalf of the Company or
for otherwise acting in good faith under this subsection 2.2D, and upon
conversion or continuation of the applicable basis for determining the interest
rate with respect to any Loans in accordance with this Agreement pursuant to any
such telephonic notice the Company shall have effected a conversion or
continuation, as the case may be, hereunder.

      Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice
of Conversion/Continuation for conversion to, or continuation of, a Eurodollar
Rate Loan (or telephonic notice in lieu thereof) shall be irrevocable on and
after the related Interest Rate Determination Date, and the Company shall be
bound to effect a conversion or continuation in accordance therewith.

      E. Post-Default Interest. Upon the occurrence and during the continuation
of any Event of Default, the outstanding principal amount of all Loans and, to
the extent permitted by applicable law, any interest payments thereon not paid
when due and any fees and other amounts then due and payable hereunder, shall
thereafter bear interest (including post-petition interest in any proceeding
under the Bankruptcy Code, or other applicable bankruptcy or insolvency laws)
payable upon demand at a rate that is 2% per annum in excess of the interest
rate otherwise payable under this Agreement with respect to the applicable Loans
(or, in the case of any such fees and other amounts, at a rate which is 2% per
annum in excess of the interest rate otherwise payable under this Agreement for
Revolving Loans bearing interest at a rate determined by reference to the Base
Rate); provided that, in the case of Eurodollar Rate Loans, upon the expiration
of the Interest Period in effect at the time any such increase in interest rate
is effective such Eurodollar Rate Loans shall thereupon become Base Rate Loans
and shall thereafter bear interest payable upon demand at a rate equal to 2% per
annum in excess of the interest rates otherwise payable under this Agreement for
Base Rate Loans that are Term A Loans, Term B Loans, or Revolving Loans, as
applicable. Payment or acceptance of the increased rates of interest provided
for in this subsection 2.2E is not a permitted alternative to timely payment and
shall not constitute a waiver of any Event of Default or otherwise prejudice or
limit any rights or remedies of the Administrative Agent or any Lender.

      F. Computation of Interest. Interest on Loans shall be computed on the
basis of a 360-day year (a 365 or 366-day year, as applicable, in the case of
Base Rate Loans based on the Prime Rate) and for the actual number of days
elapsed in the period during which it accrues. In computing interest on any
Loan, the date of the making of such Loan or the first day of an Interest Period
applicable to such Loan or, with respect to a Base Rate Loan being converted
from a Eurodollar Rate Loan, the date of conversion of such Eurodollar Rate Loan
to such Base Rate Loan, as the case may be, shall be included, and the date of
payment of such Loan or the expiration date of an Interest Period applicable to
such Loan or, with respect to a Base Rate Loan being converted to a Eurodollar
Rate Loan, the date of conversion of such Base Rate Loan to such Eurodollar Rate
Loan, as the case may be, shall be excluded; provided that if a Loan is repaid
on the same day on which it is made, one day's interest shall be paid on that
Loan.

2.3 Fees.

      A. Commitment Fees.

            (i) Revolving Loan Commitments. The Company agrees to pay to the
      Administrative Agent, for distribution to each Lender in proportion to
      that Lender's Pro Rata 


                                       49

<PAGE>

      Share of the Revolving Loan Commitments, commitment fees for the period
      from and including the date hereof to and excluding the Revolving Loan
      Commitment Termination Date equal to the sum of (x) the average of the
      daily excess of the Revolving Loan Commitments over the sum of the
      aggregate principal amount of Revolving Loans outstanding (but not any
      Swing Line Loans outstanding) plus (y) the Letter of Credit Usage
      multiplied by the Applicable Commitment Fee Percentage.

            (ii) Term Loan Commitments. The Company agrees to pay to the
      Administrative Agent, for distribution to each Lender in proportion to
      that Lender's Pro Rata Share of the applicable Commitments, commitment
      fees in respect of each type of Term Loan Commitments for the period from
      and excluding the date hereof to and excluding the earlier of October 16,
      1998 and the Closing Date equal to the product of the aggregate amount of
      such type of Term Loan Commitments and the Applicable Commitment Fee
      Percentage.

            (iii) Calculation and Payment. All of the foregoing commitment fees
      shall be calculated on the basis of a 360-day year and the actual number
      of days elapsed and shall be payable in arrears on the Closing Date, the
      last Business Day in each of March, June, September and December of each
      year, commencing in December 1998, and on the Revolving Loan Commitment
      Termination Date.

      B. Annual Administrative Fee. The Company agrees to pay to the
Administrative Agent an annual administrative fee in such amounts as may have
been or hereafter be agreed between them from time to time.

      C. Other Agent Fees. The Company agrees to pay such other fees as may have
been or hereafter be agreed upon from time to time.

2.4 Repayments, Prepayments and Reductions in Commitments; General Provisions
    Regarding Payments.

      A. Scheduled Payments of Term Loans.

            (i) Scheduled Payments of Term A Loans. The Company shall make
      principal payments on the Term A Loans in installments on the dates set
      forth below, each such installment to be in an amount equal to the
      corresponding percentages set forth below of the principal amount of the
      Term A Loans as of the Closing Date:

      ; provided that the scheduled installments of principal of the Term B
      Loans set forth above shall be reduced in connection with any voluntary or
      mandatory prepayments of the Term B Loans in accordance with subsection
      2.4C; and provided, further that the final installment specified above for
      the repayment by the Company of the Term B Loans shall be in an amount, if
      such amount is different from that specified above, sufficient to repay
      all amounts owing by the Company under this Agreement with respect to the
      Term B Loans.

      B. Prepayments and Reductions in Commitments.

            (i) Voluntary Prepayments. The Company may, upon written or
      telephonic notice to the Administrative Agent on or prior to 11:00 a.m.
      (New York time) on the date of prepayment, which notice, if telephonic,
      shall be promptly confirmed in writing, at any time and from time to time
      prepay, without premium or penalty, any Swing Line Loan on any Business
      Day in whole or in part in an aggregate minimum amount of $500,000 and
      integral multiples of $100,000 in excess of that amount. In addition, so
      long as no Swing Line Loans are then outstanding, the Company may, upon
      not less than three (3) Business Days' prior written or telephonic notice,
      promptly confirmed in writing to the Administrative Agent (which notice
      the Administrative Agent will promptly transmit by facsimile or telephone
      to each Lender), at any time and from time to time prepay, without premium
      or penalty (except as set forth in subsection 2.4B(iv) below), the Loans
      (other than Swing Line Loans) on any Business Day in whole or in part in
      an aggregate minimum amount of (a) in the case of Base Rate Loans,
      $2,000,000 and integral multiples of $500,000 in excess of that amount,
      and (b) in the case of Eurodollar Rate Loans, $2,500,000 and integral


                                       52

<PAGE>

      multiples of $500,000 in excess of that amount; provided, however, that in
      the event the Company shall prepay a Eurodollar Rate Loan other than on
      the expiration of the Interest Period applicable thereto, the Company
      shall, at the time of such prepayment, also pay any amounts payable under
      subsection 2.6D hereof. Notice of prepayment having been given as
      aforesaid, the Loans shall become due and payable on the prepayment date
      specified in such notice and in the aggregate principal amount specified
      therein. Any voluntary prepayments pursuant to this subsection 2.4B(i)
      shall be applied as specified in subsection 2.4C.

            (ii) Voluntary Reductions of Revolving Loan Commitments. The Company
      may, upon not less than three (3) Business Days' prior written or
      telephonic notice, promptly confirmed in writing to the Administrative
      Agent (which notice the Administrative Agent will promptly transmit by
      facsimile or telephone to each Lender), at any time and from time to time
      terminate in whole or permanently reduce in part, without premium or
      penalty, the Revolving Loan Commitments in an amount up to the amount by
      which the Revolving Loan Commitments exceed the Total Utilization of
      Revolving Loan Commitments at the time of such proposed termination or
      reduction; provided that any such partial reduction of the Revolving Loan
      Commitments shall be in an aggregate minimum amount of $2,500,000 and
      integral multiples of $500,000 in excess of that amount. The Company's
      notice to the Administrative Agent shall designate the date (which shall
      be a Business Day) of such termination or reduction and the amount of any
      partial reduction, and such termination or reduction of the Revolving Loan
      Commitments shall be effective on the date specified in such notice and
      shall reduce the Revolving Loan Commitment of each Lender proportionately
      to its Pro Rata Share.

            (iii) Mandatory Prepayments.

            The Loans shall be prepaid in the manner provided in subsection 2.4C
      upon the occurrence of the following circumstances:

                  (a) Prepayments from Asset Sales. No later than the first
            (1st) Business Day following the date of receipt by the Parent, the
            Company or any of its Subsidiaries of Cash Proceeds of any Asset
            Sale, the Company shall prepay the Term Loans in an amount equal to
            the Net Cash Proceeds received; provided that (I) if the Company
            shall have delivered a Reinvestment Notice to the Administrative
            Agent no later than one (1) Business Day after the consummation of
            such Asset Sale (other than Asset Sales described in Schedule 7.7
            annexed hereto) and no Default or Event of Default exists at the
            time of such consummation or delivery of such notice, the Company
            shall not be required to make any prepayment with the proceeds of
            such Asset Sale to the extent that (x) all or any portion of such
            proceeds are reinvested in Reinvestment Assets within two hundred
            seventy (270) days from the date of receipt of such proceeds, and
            (y) after giving effect thereto, the aggregate amount of proceeds
            (other than (1) Permitted Testing Center Proceeds, and (2) proceeds
            of Asset Sales described in Schedule 7.7 annexed hereto in an amount
            not to exceed $5,000,000) not used to make mandatory prepayments of
            Term Loans pursuant to this proviso and the corresponding proviso to
            subsection 2.4B(iii)(d) shall not exceed $10,000,000 measured on a
            cumulative basis from the Closing Date; (II) if at any time the
            aggregate amount of Net Cash Proceeds (including, without
            limitation, Permitted Testing Center Proceeds) in respect of which
            Reinvestment Notices have been delivered and which have not yet been
            reinvested in Reinvestment Assets or used to repay Loans shall
            exceed $10,000,000, then the Borrower shall promptly deliver all
            such Net Cash Proceeds (including the portion not in excess of
            $10,000,000) to the Collateral Agent 


                                       53

<PAGE>

            to be held and applied by it in accordance with the terms of the
            Collateral Account Agreement; and (III) on each Reinvestment
            Prepayment Date, an amount equal to the Reinvestment Prepayment
            Amount with respect to the relevant Reinvestment Event shall be
            applied to prepay the Term Loans. Concurrently with any prepayment
            of Loans pursuant to this subsection 2.4B(iii)(a), the Company shall
            deliver to the Administrative Agent an Officer's Certificate
            demonstrating in detail reasonably satisfactory to the
            Administrative Agent the derivation of the Net Cash Proceeds of the
            correlative Asset Sale from the gross sales price thereof. In
            addition, in the event that the Company shall, at any time after
            receipt of proceeds of any Reinvestment Event requiring a prepayment
            pursuant to this subsection 2.4B(iii)(a), determine that the
            prepayments previously made in respect of such Reinvestment Event
            were in an aggregate amount less than that required by the terms of
            this subsection 2.4B(iii)(a), the Company shall promptly cause to be
            made an additional prepayment of the Term Loans in an amount equal
            to the amount of any such deficit, and the Company shall
            concurrently therewith deliver to the Administrative Agent an
            Officer's Certificate demonstrating the derivation of the additional
            proceeds resulting in such deficit.

                  (b) Prepayments Due to Issuance of Debt. On or prior to the
            first (1st) Business Day after receipt by the Parent, the Company or
            any of its Subsidiaries of any proceeds of any Indebtedness (other
            than the Loans and any other Indebtedness permitted by this
            Agreement), the Company shall prepay the Term Loans in an amount
            equal to the amount of such proceeds; provided that payment or
            acceptance of the amounts provided for in this subsection
            2.4B(iii)(b) shall not constitute a waiver of any Event of Default
            resulting from the incurrence of such Indebtedness or otherwise
            prejudice any rights or remedies of the Administrative Agent or any
            Lender.

                  (c) Prepayments Due to Issuance of Equity Securities. On or
            prior to the first (1st) Business Day after receipt by the Parent,
            the Company or any of their respective Subsidiaries of any Equity
            Proceeds (other than, so long as no Default or Event of Default
            shall have occurred and be continuing or result therefrom, (x)
            Equity Proceeds of up to $5,000,000 in the aggregate received by the
            Parent, the Company or any of their respective Subsidiaries as
            payment of the exercise price under any option for any shares of
            Capital Stock of the Parent held by any officer or employee of the
            Parent, the Company or any of their respective Subsidiaries, and (y)
            Equity Proceeds received by the Parent, the Company or any of their
            respective Subsidiaries solely to the extent that such Equity
            Proceeds are used within one Business Day of such receipt to finance
            a Permitted Acquisition and are not realized from a Public
            Offering), the Company shall prepay the Term Loans in an amount
            equal to such Equity Proceeds.

                  (d) Prepayments Due to Insurance and Condemnation Proceeds. No
            later than the first (1st) Business Day following the date of
            receipt by the Company or any of its Subsidiaries of any cash
            payments under any insurance policy as a result of any damage to or
            loss of all or any portion of the Collateral or any other tangible
            asset (net of actual and documented reasonable costs incurred by the
            Company or any of its Subsidiaries in connection with adjustment and
            settlement thereof, "Insurance Proceeds") or any proceeds resulting
            from the taking of assets by the power of eminent domain,
            condemnation or otherwise (net of actual and documented reasonable
            costs incurred by the Company or any of its Subsidiaries in
            connection with adjustment and settlement thereof, 


                                       54

<PAGE>

            "Condemnation Proceeds") (any such event resulting in the recovery
            of Insurance Proceeds or Condemnation Proceeds, a "Recovery Event"),
            the Company shall prepay the Term Loans in an amount equal to the
            Insurance Proceeds or Condemnation Proceeds, as the case may be,
            received; provided, that, if the Company shall have delivered a
            Reinvestment Notice to the Administrative Agent no later than five
            (5) Business Days prior to the consummation of such Recovery Event
            and no Default or Event of Default exists at the time of such
            consummation or delivery of such notice, the Company shall not be
            required to make any prepayment with the proceeds of such Recovery
            Event to the extent that (x) all or any portion of such proceeds are
            reinvested in Reinvestment Assets within one hundred eighty (180)
            days from the date of receipt of such proceeds, and (y) after giving
            effect thereto, the aggregate amount of proceeds not used to make
            mandatory prepayments of Term Loans pursuant to this proviso and the
            corresponding proviso to subsection 2.4B(iii)(a) shall not exceed
            $10,000,000 measured on a cumulative basis from the Closing Date;
            provided, further, that, on each Reinvestment Prepayment Date, an
            amount equal to the Reinvestment Prepayment Amount with respect to
            the relevant Reinvestment Event shall be applied to prepay the Term
            Loans. Concurrently with any prepayment of Loans pursuant to this
            subsection 2.4B(iii)(d), the Company shall deliver to the
            Administrative Agent an Officer's Certificate demonstrating in
            detail reasonably satisfactory to the Administrative Agent the
            derivation of the Insurance Proceeds or Condemnation Proceeds, as
            the case may be, of the correlative Recovery Event. In addition, in
            the event that the Company shall, at any time after receipt of
            proceeds of any Reinvestment Event requiring a prepayment pursuant
            to this subsection 2.4B(iii)(d), determine that the prepayments
            previously made in respect of such Reinvestment Event were in an
            aggregate amount less than that required by the terms of this
            subsection 2.4B(iii)(d), the Company shall promptly cause to be made
            an additional prepayment of the Term Loans in an amount equal to the
            amount of any such deficit, and the Company shall concurrently
            therewith deliver to the Administrative Agent an Officer's
            Certificate demonstrating the derivation of the additional proceeds
            resulting in such deficit.

                  (e) Prepayments Due to Reductions or Restrictions of Revolving
            Loan Commitments. The Company shall prepay the Swing Line Loans
            and/or Revolving Loans from time to time to the extent necessary so
            that (1) the Total Utilization of Revolving Loan Commitments shall
            not at any time exceed the Revolving Loan Commitments then in
            effect, and (2) the aggregate principal amount of all outstanding
            Swing Line Loans shall not at any time exceed the Swing Line Loan
            Commitment then in effect. All Swing Line Loans shall be prepaid in
            full prior to the prepayment of any Revolving Loans pursuant to this
            subsection 2.4B(iii)(e). If at any time that there are no Revolving
            Loans and Swing Line Loans outstanding (whether after giving effect
            to any prepayment thereof pursuant to this subclause (e) or
            otherwise) the Total Utilization of Revolving Loan Commitments
            exceeds the Revolving Loan Commitment, the Company shall deposit
            into the Collateral Account such amounts as are necessary so that,
            after giving effect thereto, the amount on deposit in the Collateral
            Account pursuant to this subclause (e) is at least equal to such
            excess.

                  (f) Prepayments from Consolidated Excess Cash Flow. In the
            event that there shall be Consolidated Excess Cash Flow for any
            Fiscal Year (commencing with the Fiscal Year ending December 31,
            1999), the Company shall, no later than ninety-five (95) days after
            the end of such Fiscal Year, prepay the Term Loans in an aggregate
            amount 


                                       55

<PAGE>

            equal to (x) if the Leverage Ratio is greater than 3.0x, 75% of such
            Consolidated Excess Cash Flow, and (y) if the Leverage Ratio is
            equal to or less than 3.0x, 50% of such Consolidated Excess Cash
            Flow.

                  (g) Prepayments Due to Termination or Cancellation of State
            Contracts. On or prior to the first (1st) Business Day after receipt
            by the Company or any of its Subsidiaries of any termination
            payments, settlement or judgment awards or similar payments in
            connection with, or as a result of the termination or cancellation
            of, any State Contract, the Company shall prepay the Term Loans in
            an amount equal to the amount of such termination payments, awards
            or similar payments; provided that payment or acceptance of the
            amounts provided for in this subsection 2.4B(iii)(g) shall not
            constitute a waiver of any Default or Event of Default resulting
            from the termination or cancellation of any State Contract or
            otherwise prejudice any rights or remedies of the Agents or any
            Lender.

            (iv) Prepayment Fee. Together with any prepayment of the Loans, the
      Company shall pay a prepayment fee as follows:

                  (a) Voluntary Prepayments. Any voluntary prepayment of Term B
            Loans required on or prior to (x) the first (1st) Anniversary of the
            Closing Date pursuant to subsection 2.4B(i) shall be accompanied by
            a prepayment fee in an amount equal to 2% of the amount of such
            prepayment, and (y) the second (2nd) Anniversary of the Closing Date
            pursuant to subsection 2.4B(i) shall be accompanied by a prepayment
            fee in an amount equal to 1% of the amount of such prepayment.

                  (b) Mandatory Prepayments. Any mandatory prepayment of Term B
            Loans required on or prior to the second (2nd) Anniversary of the
            Closing Date pursuant to subsection 2.4B(iii) (other than subsection
            2.4(B)(iii)(f)) shall be accompanied by a prepayment fee in an
            amount equal to 1% of the amount of such prepayment.

                  (c) Reimbursement. Except as provided in subclauses (a) and
            (b) above, no premium or penalty shall be payable as a result of any
            prepayment of the Loans; provided, that any and all prepayments of
            the Loans shall be accompanied by payment of any amounts owing or
            payable to the Lenders under subsection 2.6D.

      C. Application of Prepayments.

            (i) Application of Prepayments by Type of Loans. Any voluntary
      prepayments pursuant to subsection 2.4B(i) shall be applied: first to
      repay outstanding Swing Line Loans to the full extent thereof, and second
      to repay the types of Loans as specified in the correlative notice of
      prepayment and, absent such specification, to repay outstanding Term
      Loans. Any amount required to be applied as a prepayment of Term Loans
      pursuant to subsection 2.4B(iii) or this subsection 2.4C(i) shall be
      applied to prepay the two (2) different tranches of Term Loans ratably to
      the full extent thereof; provided that, in the case of any such prepayment
      of the Term Loans, (a) the Company shall use reasonable efforts to notify
      the Lenders of such prepayment five (5) Business Days in advance of
      payment to the Administrative Agent of such amount, (b) upon receipt of
      such payment, the Administrative Agent shall notify the Lenders of such
      payment, (c) in the event any Lender with Term B Loans elects to waive
      such Lender's right to receive such 


                                       56

<PAGE>

      prepayment in respect of any such Loans, such Lender shall so advise the
      Administrative Agent in writing no later than the close of business on the
      date it receives such notice from the Administrative Agent and (d) upon
      receipt of such written advice from such Lender, the Administrative Agent
      shall apply the amount waived by such Lender to prepay the Term A Loans.

            (ii) Application of Prepayments of Term Loans to Installments. The
      amount of any voluntary prepayments of Term A Loans or Term B Loans, as
      applicable, shall be applied to reduce each scheduled installment thereof
      set forth in subsection 2.4A(i) or 2.4A(ii), as applicable, that is unpaid
      in the inverse order that such installments are scheduled to occur. The
      amount of any mandatory prepayments applied to Term A Loans or Term B
      Loans, as applicable, shall be applied to ratably reduce each scheduled
      installment of principal thereof set forth in subsection 2.4A(i) or
      2.4A(ii), as applicable.

            (iii) Application of Prepayments of Loans to Base Rate Loans and
      Eurodollar Rate Loans. Considering Loans constituting Term A Loans, Term B
      Loans and Revolving Loans being prepaid separately, any prepayment thereof
      shall be applied first to Base Rate Loans to the full extent thereof
      before application to Eurodollar Rate Loans, in each case in a manner
      which minimizes the amount of any payments required to be made by the
      Company pursuant to subsection 2.6D.

            (iv) Application of Prepayment Fee. Any prepayment fee paid in
      connection with any prepayment shall be paid ratably to the applicable
      holders of the Loans then being prepaid.

      D. Application of Proceeds of Collateral and Payments Under Guaranties.

            (i) Application of Proceeds of Collateral. Except as provided in
      subsection 2.4B(iii) with respect to prepayments from Net Cash Proceeds,
      Insurance Proceeds or Condemnation Proceeds, all proceeds received by the
      Administrative Agent or the Collateral Agent, as the case may be, in
      respect of any sale of, collection from, or other realization upon all or
      any part of the Collateral under any Collateral Document may, in the
      discretion of the Collateral Agent, be held by the Collateral Agent as
      Collateral for, and/or (then or at any time thereafter) applied in full or
      in part by the Administrative Agent against, the applicable Secured
      Obligations (as defined in such Collateral Document) in the following
      order of priority:

                  (a) to the payment of all costs and expenses of such sale,
            collection or other realization, including without limitation
            reasonable compensation to such Agents and their agents and counsel,
            and all other reasonable expenses, liabilities and advances made or
            incurred by such Agents in connection therewith, and all amounts for
            which such Agents are entitled to indemnification under such
            Collateral Document and all advances made by the Collateral Agent
            thereunder for the account of the applicable Loan Party, and to the
            payment of all reasonable costs and expenses paid or incurred by the
            Collateral Agent in connection with the exercise of any right or
            remedy under such Collateral Document, all in accordance with the
            terms of this Agreement and such Collateral Document;

                  (b) thereafter, to the extent of any excess proceeds, to the
            payment of all other such Secured Obligations for the ratable
            benefit of the holders thereof; and

                  (c) thereafter, to the extent of any excess proceeds, to the
            payment to or upon 


                                       57

<PAGE>

            the order of such Loan Party or to whosoever may be lawfully
            entitled to receive the same or as a court of competent jurisdiction
            may direct.

            (ii) Application of Payments Under Guaranties. All payments received
      by the Administrative Agent under any Guaranty shall be applied promptly
      from time to time by the Administrative Agent in the following order of
      priority:

                  (a) to the payment of the reasonable costs and expenses of any
            collection or other realization under such Guaranty, including
            without limitation reasonable compensation to the Administrative
            Agent and its agents and counsel, and all expenses, liabilities and
            advances made or incurred by the Administrative Agent in connection
            therewith, all in accordance with the terms of this Agreement and
            such Guaranty;

                  (b) thereafter, to the extent of any excess such payments, to
            the payment of all other Guarantied Obligations (as defined in such
            Guaranty) for the ratable benefit of the holders thereof; and

                  (c) thereafter, to the extent of any excess such payments, to
            the payment to the applicable Guarantor or to whosoever may be
            lawfully entitled to receive the same or as a court of competent
            jurisdiction may direct.

      E. General Provisions Regarding Payments.

            (i) Manner and Time of Payment. All payments by the Company of
      principal, interest, fees and other Obligations hereunder and under the
      Notes shall be made in same day funds and without defense, setoff or
      counterclaim, free of any restriction or condition, and delivered to the
      Administrative Agent not later than 12:00 Noon (New York time) on the date
      due at the Funding and Payment Office for the account of the Lenders;
      funds received by the Administrative Agent after that time on such due
      date shall be deemed to have been paid by the Company on the next
      succeeding Business Day. The Company hereby authorizes the Administrative
      Agent to charge its accounts with the Administrative Agent in order to
      cause timely payment to be made to the Administrative Agent of all
      principal, interest, fees and expenses due hereunder (subject to
      sufficient funds being available in its accounts for that purpose).

            (ii) Application of Payments to Principal, Interest and Prepayment
      Fees. Except as provided in subsection 2.2C, all payments in respect of
      the principal amount of any Loan shall include payment of accrued interest
      and prepayment fees, if any, on the principal amount being repaid or
      prepaid, and all such payments (and in any event any payments made in
      respect of any Loan on a date when interest is due and payable with
      respect to such Loan) shall be applied to the payment of interest and
      prepayment fees, if any, before application to principal.

            (iii) Apportionment of Payments. Aggregate principal, prepayment
      fees and interest payments shall be apportioned among all outstanding
      Loans to which such payments relate, in each case proportionately to the
      Lenders' respective Pro Rata Shares. The Administrative Agent shall
      promptly distribute to each Lender, at its applicable Lending Office
      specified on Schedule 2.1 or at such other address as such Lender may
      request, its Pro Rata Share of all such payments received by the
      Administrative Agent and the commitment fees of such Lender when received
      by the Administrative Agent pursuant to subsection 2.3. Notwithstanding
      the foregoing provisions of 


                                       58

<PAGE>

      this subsection 2.4E(iii) if, pursuant to the provisions of subsection
      2.6C, any Notice of Conversion/Continuation is withdrawn as to any
      Affected Lender or if any Affected Lender makes Base Rate Loans in lieu of
      its Pro Rata Share of any Eurodollar Rate Loans, the Administrative Agent
      shall give effect thereto in apportioning payments received thereafter.

            (iv) Payments on Business Days. Except if expressly provided
      otherwise, whenever any payment to be made hereunder shall be stated to be
      due on a day that is not a Business Day, such payment shall be made on the
      next succeeding Business Day and such extension of time shall be included
      in the computation of the payment of interest hereunder or of the
      commitment fees hereunder, as the case may be.

            (v) Notation of Payment. Each Lender agrees that before disposing of
      any Note held by it, or any part thereof (other than by granting
      participations therein), that Lender will make a notation thereon of all
      Loans evidenced by that Note and all principal payments previously made
      thereon and of the date to which interest thereon has been paid; provided
      that the failure to make (or any error in the making of) a notation of any
      Loan made under such Note shall not limit or otherwise affect such
      disposition or the obligations of the Company hereunder or under such Note
      with respect to any Loan or any payments of principal or interest on such
      Note.

2.5 Use of Proceeds.

      A. Term Loans and Initial Revolving Loans. The proceeds of Term Loans and
the Initial Revolving Loans made to Company shall be applied, together with the
proceeds of the Senior Discount Notes, the Senior Subordinated Notes and the
Equity Contribution and approximately $77,000,000 of cash on hand at ENR to (i)
finance the purchase price for the Shares (or portion thereof) payable in
connection with the Shares Acquisitions and the ENR Merger consideration, (ii)
repay (or, in the case of the Existing Senior Notes and Existing Senior
Subordinated Notes, purchase or defease to redemption) in full the Existing
Indebtedness, (iii) repay or make, as applicable, the intercompany loans
described in the definition of "Transactions" and (iv) pay the Transaction
Costs.

      B. Revolving Loans; Swing Line Loans. The proceeds of any Revolving Loans
(other than the Revolving Loans referenced in subsection 2.5A) and any Swing
Line Loans shall be applied by the Company for working capital and general
corporate purposes of the Company and its Subsidiaries other than Excluded
Foreign Subsidiaries.

      C. Compliance With Laws. The Company undertakes that no portion of the
proceeds of any Loans or other extensions of credit under this Agreement shall
be used by any Loan Party in any manner which would be illegal under, or which
would cause the invalidity or unenforceability (in each case in whole or in
part) of any Loan Document under, any applicable law.

      D. Margin Regulations. Without limiting the generality of subsection 2.5C,
no portion of the proceeds of any borrowing under this Agreement shall be used
by the Company or any of its Subsidiaries in any manner that might cause the
borrowing or the application of such proceeds to violate Regulation U,
Regulation T or Regulation X of the Board of Governors of the Federal Reserve
System or any other regulation of such Board or to violate the Exchange Act, in
each case as in effect on the date or dates of such borrowing and such use of
proceeds.

2.6 Special Provisions Governing Eurodollar Rate Loans.


                                       59

<PAGE>

      Notwithstanding any other provision of this Agreement to the contrary, the
following provisions shall govern with respect to Eurodollar Rate Loans as to
the matters covered:

      A. Determination of Applicable Interest Rate. As soon as practicable after
11:00 A.M. (New York time) on each Interest Rate Determination Date, the
Administrative Agent shall determine (which determination shall, absent manifest
error, be final, conclusive and binding upon all parties) the interest rate that
shall apply to the Eurodollar Rate Loans for which an interest rate is then
being determined for the applicable Interest Period and shall promptly give
notice thereof (in writing or by telephone confirmed in writing) to the Company
and each Lender.

      B. Inability to Determine Applicable Interest Rate. In the event that the
Administrative Agent shall have reasonably determined (which determination shall
be final and conclusive and binding upon all parties hereto), on any Interest
Rate Determination Date with respect to any Eurodollar Rate Loans, that by
reason of circumstances arising after the date of this Agreement affecting the
London interbank market, adequate and fair means do not exist for ascertaining
the interest rate applicable to such Loans on the basis provided for in the
definition of Reserve Adjusted Eurodollar Rate the Administrative Agent shall on
such date give notice (by telecopy or by telephone confirmed in writing) to the
Company and each Lender of such determination, whereupon (i) no Loans may be
made or continued as, or converted to, Eurodollar Rate Loans, until such time as
the Administrative Agent notifies the Company and the Lenders that the
circumstances giving rise to such notice no longer exist (such notification not
to be unreasonably withheld or delayed) and (ii) any Notice of Borrowing or
Notice of Conversion/Continuation given by the Company with respect to the Loans
in respect of which such determination was made shall be deemed to be rescinded
by the Company.

      C. Illegality or Impracticability of Eurodollar Rate Loans. In the event
that on any date any Lender shall have reasonably determined (which
determination shall be final and conclusive and binding upon all parties hereto
but shall be made only after consultation with the Company and the
Administrative Agent) that the making, maintaining or continuation of its
Eurodollar Rate Loans (i) has become unlawful as a result of compliance by such
Lender in good faith with any law, treaty, governmental rule, regulation,
guideline or order (or would conflict with any such treaty, governmental rule,
regulation, guideline or order not having the force of law even though the
failure to comply therewith would not be unlawful) or (ii) has become
impracticable, or would cause such Lender material hardship, as a result of
contingencies occurring after the date of this Agreement which materially and
adversely affect the London interbank market, then, and in any such event, such
Lender shall be an "Affected Lender" and it shall on that day give notice (by
telecopy or by telephone confirmed in writing) to the Company and the
Administrative Agent of such determination (which notice the Administrative
Agent shall promptly transmit to each other Lender). Thereafter (a) the
obligation of the Affected Lender to make Loans as, or to convert Loans to,
Eurodollar Rate Loans, shall be suspended until such notice shall be withdrawn
by the Affected Lender, (b) to the extent such determination by the Affected
Lender relates to a Eurodollar Rate Loan then being requested by the Company
pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, the
Affected Lender shall make such Loan as (or convert such Loan to, as the case
may be) a Base Rate Loan, (c) the Affected Lender's obligation to maintain its
outstanding Eurodollar Rate Loans, as the case may be (the "Affected Loans"),
shall be terminated at the earlier to occur of the expiration of the Interest
Period then in effect with respect to the Affected Loans or when required by
law, and (d) the Affected Loans shall automatically convert into Base Rate Loans
on the date of such termination. Notwithstanding the foregoing, to the extent a
determination by an Affected Lender as described above relates to a Eurodollar
Rate Loan then being requested by the Company pursuant to a 


                                       60

<PAGE>

Notice of Borrowing or a Notice of Conversion/Continuation, the Company shall
have the option, subject to the provisions of subsection 2.6D, to rescind such
Notice of Borrowing or Notice of Conversion/ Continuation as to all Lenders by
giving notice (by telecopy or by telephone confirmed in writing) to the
Administrative Agent of such rescission on the date on which the Affected Lender
gives notice of its determination as described above (which notice of rescission
the Administrative Agent shall promptly transmit to each other Lender). Except
as provided in the immediately preceding sentence, nothing in this subsection
2.6C shall affect the obligation of any Lender other than an Affected Lender to
make or maintain Loans as, or to convert Loans to, Eurodollar Rate Loans in
accordance with the terms of this Agreement.

      D. Compensation For Breakage or Non-Commencement of Interest Periods. The
Company shall compensate each Lender, upon written request by that Lender (which
request shall set forth the basis for requesting such amounts), for all
reasonable losses, expenses and liabilities (including, without limitation, any
interest paid by that Lender to the Lenders of funds borrowed by it to make or
carry its Eurodollar Rate Loans and any actual loss, expense or liability
sustained by that Lender in connection with the liquidation or re-employment of
such funds) which that Lender may sustain: (i) if for any reason (other than a
default by that Lender) a borrowing of any Eurodollar Rate Loan does not occur
on a date specified therefor in a Notice of Borrowing or a telephonic request
for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan
does not occur on a date specified therefor in a Notice of
Conversion/Continuation or a telephonic request for conversion or continuation,
(ii) if any prepayment (including any prepayment pursuant to subsection 2.4B) or
conversion of any of its Eurodollar Rate Loans occurs on a date that is not the
last day of an Interest Period applicable to that Loan, (iii) if any prepayment
of any of its Eurodollar Rate Loans is not made on any date specified in a
notice of prepayment given by the Company, or (iv) as a consequence of any other
default by the Company in the repayment of its Eurodollar Rate Loans when
required by the terms of this Agreement.

      E. Booking of Eurodollar Rate Loans. Any Lender may make, carry or
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of that Lender.

      F. Assumptions Concerning Funding of Eurodollar Rate Loans. Calculation of
all amounts payable to a Lender under this subsection 2.6 and under subsection
2.7A shall be made as though that Lender had actually funded each of its
relevant Eurodollar Rate Loans through the purchase of a Eurodollar deposit
bearing interest at the rate obtained pursuant to clause (i) of the definition
of Reserve Adjusted Eurodollar Rate in an amount equal to the amount of such
Eurodollar Rate Loan and having a maturity comparable to the relevant Interest
Period and, through the transfer of such Eurodollar deposit from an offshore
office of that Lender to a domestic office of that Lender in the United States
of America; provided, however, that each Lender may fund each of its Eurodollar
Rate Loans in any manner it sees fit and the foregoing assumptions shall be
utilized only for the purposes of calculating amounts payable under this
subsection 2.6 and under subsection 2.7A.

      G. Eurodollar Rate Loans After Default. After the occurrence of and during
the continuation of a Default or Event of Default, (i) the Company may not elect
to have a Loan be made or maintained as, or converted to, a Eurodollar Rate Loan
after the expiration of any Interest Period then in effect for that Loan and
(ii) subject to the provisions of subsection 2.6D, any Notice of Borrowing or
Notice of Conversion/Continuation given by the Company with respect to a
requested borrowing or conversion/continuation that has not yet occurred shall
be deemed to be rescinded by the Company.


                                       61

2.7 Increased Costs; Taxes; Capital Adequacy.

      A. Compensation for Increased Costs and Taxes. Subject to the provisions
of subsection 2.7B, in the event that any Lender shall determine (which
determination shall, absent manifest error, be final and conclusive and binding
upon all parties hereto) that any law, treaty or governmental rule, regulation
or order, or any change therein or in the interpretation, administration or
application thereof (including the introduction of any new law, treaty or
governmental rule, regulation or order), or any determination of a court or
governmental authority, in each case that becomes effective after the Closing
Date, or compliance by such Lender with any guideline, request or directive
issued or made after the date hereof by any central bank or other governmental
or quasi-governmental authority (whether or not having the force of law):

            (i) results in a change in the basis of taxation of such Lender (or
      its applicable lending office) (other than a change with respect to any
      Tax on the overall net income of such Lender) with respect to this
      Agreement or any of its obligations hereunder or any payments to such
      Lender (or its applicable lending office) of principal, interest, fees or
      any other amount payable hereunder;

            (ii) imposes, modifies or holds applicable any reserve (including
      without limitation any marginal, emergency, supplemental, special or other
      reserve), special deposit, compulsory loan, FDIC insurance or similar
      requirement against assets held by, or deposits or other liabilities in or
      for the account of, or advances or loans by, or other credit extended by,
      or any other acquisition of funds by, any office of such Lender (other
      than any such reserve or other requirements with respect to Eurodollar
      Rate Loans that are reflected in the definition of Reserve Adjusted
      Eurodollar Rate); or

            (iii) imposes any other condition (other than with respect to a Tax
      matter) on or affecting such Lender (or its applicable lending office) or
      its obligations hereunder, or the London interbank market;

and the result of any of the foregoing is to increase the cost to such Lender of
agreeing to make, making or maintaining Eurodollar Rate Loans hereunder or to
reduce any amount received or receivable by such Lender (or its applicable
lending office) with respect thereto; then, in any such case, the Lender shall
promptly notify the Company and the Administrative Agent thereof and the Company
shall promptly pay to such Lender, upon receipt of the statement referred to in
the next sentence, such additional amount or amounts (in the form of an
increased rate of, or a different method of calculating, interest or otherwise
as such Lender shall reasonably determine) as may be necessary to compensate
such Lender for any such increased cost or reduction in amounts received or
receivable hereunder. Such Lender shall deliver to the Company (with a copy to
the Administrative Agent) a written statement, setting forth in reasonable
detail the basis for calculating the additional amounts owed to such Lender
under this subsection 2.7A, which statement shall be conclusive and binding upon
all parties hereto absent manifest error.

      B. Withholding of Taxes.

            (i) Payments to Be Free and Clear. All sums payable by the Company
      under this Agreement and the other Loan Documents shall (except to the
      extent required by law) be paid free and clear of, and without any
      deduction or withholding on account of, any Tax (other than a Tax on the
      overall net income of the Administrative Agent or any Lender) imposed,
      levied, collected, 


                                       62

<PAGE>

      withheld or assessed by or within the United States of America.

            (ii) Withholding of Taxes. Subject to the provisions of subsection
      2.7B(iii), if the Company or any other Person is required by law to make
      any deduction or withholding on account of any Tax (other than a Tax on
      the overall net income of the Administrative Agent or any Lender) from any
      sum paid or payable by the Company to the Administrative Agent or any
      Lender under any of the Loan Documents:

                  (a) The Company shall notify the Administrative Agent of any
            such requirement or any change in any such requirement as soon as
            practicable;

                  (b) The Company shall pay any such Tax before the date on
            which penalties attach thereto, such payment to be made (if the
            liability to pay is imposed on the Company) for its own account or
            (if that liability is imposed on the Administrative Agent or such
            Lender, as the case may be) on behalf of and in the name of the
            Administrative Agent or such Lender;

                  (c) the sum payable by the Company in respect of which the
            relevant deduction, withholding or payment is required shall be
            increased to the extent necessary to ensure that, after the making
            of that deduction, withholding or payment, the Administrative Agent
            or such Lender, as the case may be, receives on the due date a net
            sum equal to what it would have received had no such deduction,
            withholding or payment of such tax been required or made; and

                  (d) within 30 days after paying any sum from which it is
            required by law to make any deduction or withholding, and within 30
            days after the due date of payment of any Tax which it is required
            by clause (b) above to pay, the Company shall deliver to the
            Administrative Agent evidence satisfactory to the other affected
            parties of such deduction, withholding or payment and of the
            remittance thereof to the relevant taxing or other authority;

provided that no such additional amount shall be required to be paid to any
Lender under clause (c) above except to the extent that any change after the
Closing Date or after the date of the Assignment Agreement pursuant to which
such Lender became a Lender (in the case of each other Lender) in any such
requirement for a deduction, withholding or payment as is mentioned therein
shall result in an increase in the rate of such deduction, withholding or
payment from that in effect at the date of this Agreement or at the date of such
Assignment Agreement, as the case may be, in respect of payments to such Lender.

            (iii) Evidence of Exemption from U.S. Withholding Tax.

                  (a) Each Lender that is not a United States Person (as such
            term is defined in Section 7701(a)(30) of the Internal Revenue Code)
            for U.S. federal income tax purposes (for purposes of this
            subsection 2.7B(iii), a "Non-US Lender") shall deliver to each of
            the Administrative Agent and the Company, on or prior to the Closing
            Date, in the case of a Lender that is an assignee or transferee of
            an interest under this Agreement pursuant to Sections 10.1, or on or
            prior to the date of the Assignment Agreement pursuant to which it
            becomes a Lender, and at such other times as may be necessary in the
            determination of the Company or the Administrative Agent (each in
            the reasonable exercise of its discretion), (1) two original copies
            of Internal Revenue Service Form 1001 or 4224 (or 


                                       63

<PAGE>

            any successor forms), accurately completed and duly executed by such
            Lender, together with any other certificate or statement of
            exemption required under the Internal Revenue Code or the
            regulations issued thereunder to establish that such Lender is not
            subject to deduction or withholding of United States federal income
            tax with respect to any payments to such Lender of principal,
            interest, fees or other amounts payable under any of the Loan
            Documents or (2) if such Lender is not a "bank" or other Person
            described in Section 881(c)(3) of the Internal Revenue Code and
            cannot deliver either Internal Revenue Service Form 1001 or 4224
            pursuant to clause (1) above, a Certificate of Non-Bank Status
            together with an original copy of Internal Revenue Service Form W-8
            (or any successor form), properly completed and duly executed by
            such Lender, together with any other certificate or statement of
            exemption required under the Internal Revenue Code or the
            regulations issued thereunder to establish that such Lender is not
            subject to deduction or withholding of United States federal income
            tax with respect to any payments to such Lender of interest payable
            under any of the Loan Documents.

                  (b) Each Lender required to deliver any forms, certificates or
            other evidence with respect to United States federal income tax
            withholding matters pursuant to subsection 2.7B(iii)(a) hereby
            agrees, from time to time after the initial delivery by such Lender
            of such forms, certificates or other evidence, whenever a lapse in
            time or change in circumstances renders such forms, certificates or
            other evidence obsolete or inaccurate in any material respect, such
            Lender shall (1) deliver to each of the Administrative Agent and the
            Company two new original copies of Internal Revenue Service Form
            1001 or 4224, or a Certificate of Non-Bank Status and an original
            copy of Internal Revenue Service Form W-8, as the case may be,
            accurately completed and duly executed by such Lender, together with
            any other certificate or statement of exemption required in order to
            confirm or establish that such Lender is not subject to deduction or
            withholding of or is subject to a reduced rate of withholding of
            United States federal income tax with respect to payments to such
            Lender under the Loan Documents or (2) immediately notify the
            Administrative Agent and the Company of its inability to deliver any
            such forms, certificates or other evidence.

                  (c) The Company shall not be required to pay any additional
            amount to any Non-US Lender under clause (c) of subsection 2.7B(ii)
            in respect of deductions or withholdings of United States federal
            income taxes if such Lender shall have failed to satisfy the
            requirements of subsection 2.7B(iii)(a) or 2.7B(iii)(b); provided
            that if such Lender shall have satisfied such requirements on the
            Closing Date or on the date of the Assignment Agreement pursuant to
            which it became a Lender (in the case of each other Lender), nothing
            in this subsection 2.7B(iii)(c) shall relieve the Company of its
            obligation to pay any additional amounts pursuant to clause (c) of
            subsection 2.7B(ii) in the event that, as a result of any change
            after the Closing Date in any applicable law, treaty or governmental
            rule, regulation or order, or any change in the interpretation,
            administration or application thereof, such Lender is no longer
            properly entitled to deliver forms, certificates or other evidence
            at a subsequent date establishing the fact that such Lender is not
            subject to withholding as described in subsection 2.7B(iii)(a) or
            2.7B(iii)(b).

      C. Capital Adequacy Adjustment. If any Lender shall have determined that
the adoption, effectiveness, phase-in or applicability after the Closing Date of
any law, rule or regulation (or any provision thereof) regarding capital
adequacy, or any change therein or in the interpretation or 


                                       64

<PAGE>

administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or its applicable lending office) with any guideline, request or
directive regarding capital adequacy (whether or not having the force of law) of
any such governmental authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on the capital of such Lender or
any corporation controlling such Lender as a consequence of, or with reference
to, such Lender's Loans or Commitments or Letters of Credit or participations
therein or other obligations hereunder with respect to the Loans or the Letters
of Credit to a level below that which such Lender reasonably determines such
Lender or such controlling corporation could have achieved but for such
adoption, effectiveness, phase-in, applicability, change or compliance (taking
into consideration the policies of such Lender or such controlling corporation
with regard to capital adequacy), then from time to time, within fifteen
Business Days after receipt by the Company from such Lender of the statement
referred to in the next sentence, the Company shall pay to such Lender such
additional amount or amounts as will compensate such Lender or such controlling
corporation on an after-tax basis for such reduction. Such Lender shall deliver
to the Company (with a copy to the Administrative Agent) a written statement,
setting forth in reasonable detail the basis of the calculation of such
additional amounts, which statement shall be conclusive and binding upon all
parties hereto absent manifest error.

      D. Substitute Lenders. In the event the Company is required under the
provisions of this subsection 2.7 to make payments in a material amount to any
Lender or in the event any Lender fails to lend to the Company in accordance
with this Agreement, the Company may, so long as no Default or Event of Default
shall have occurred and be continuing, elect to terminate such Lender as a party
to this Agreement; provided that, concurrently with such termination, (i) the
Company shall pay that Lender all principal, interest and fees and other amounts
(including without limitation amounts, if any, owed under this subsection 2.7)
due to be paid to such Lender with respect to all periods through such date of
termination, (ii) another financial institution satisfactory to the Company and
the Administrative Agent (or, in the event the Administrative Agent is also the
Lender to be terminated, the successor Administrative Agent) shall agree, as of
such date, to become a Lender for all purposes under this Agreement (whether by
assignment or amendment) and to assume all obligations of the Lender to be
terminated as of such date, and (iii) all documents and supporting materials
necessary, in the judgment of the Administrative Agent (or, in the event the
Administrative Agent is also the Lender to be terminated, the successor
Administrative Agent) to evidence the substitution of such Lender shall have
been received and approved by the Administrative Agent as of such date.

2.8 Obligation of Lenders and Issuing Bank to Mitigate.

      Each Lender and the Issuing Bank agrees that, as promptly as practicable
after the officer of such Lender or the Issuing Bank responsible for
administering the Loans or Letters of Credit of such Lender or the Issuing Bank,
as the case may be, becomes aware of the occurrence of an event or the existence
of a condition that would cause such Lender to become an Affected Lender or that
would entitle such Lender or the Issuing Bank to receive payments under
subsection 2.7 or subsection 3.6, it will, to the extent not inconsistent with
the internal policies of such Lender or the Issuing Bank and any applicable
legal or regulatory restrictions, use reasonable efforts (i) to make, issue,
fund or maintain the Commitments of such Lender or the affected Loans or Letters
of Credit of such Lender or the Issuing Bank through another lending or letter
of credit office of such Lender or the Issuing Bank, or (ii) take such other
measures as such Lender or the Issuing Bank may deem reasonable, if as a result
thereof the circumstances which 


                                       65

<PAGE>

would cause such Lender to be an Affected Lender would cease to exist or the
additional amounts which would otherwise be required to be paid to such Lender
or the Issuing Bank pursuant to subsection 2.7 or subsection 3.6 would be
materially reduced and if, as determined by such Lender or the Issuing Bank in
its sole discretion, the making, issuing, funding or maintaining of such
Commitments or Loans or Letters of Credit through such other the lending or
letter of credit office or in accordance with such other measures, as the case
may be, would not otherwise materially adversely affect such Commitments or
Loans or Letters of Credit or the interests of such Lender or the Issuing Bank;
provided that such Lender or the Issuing Bank will not be obligated to utilize
such other lending or letter of credit office pursuant to this subsection 2.8
unless the Company agrees to pay all incremental expenses incurred by such
Lender or the Issuing Bank as a result of utilizing such other lending or letter
of credit office. A certificate as to the amount of any such expenses payable by
the Company pursuant to this subsection 2.8 (setting forth in reasonable detail
the basis for requesting such amount) submitted by such Lender or the Issuing
Bank to the Company (with a copy to the Administrative Agent) shall be
conclusive absent manifest error.

                                   SECTION 3.
                                LETTERS OF CREDIT

3.1 Issuance of Letters of Credit and Lenders' Purchase of Participations
    Therein.

      A. Letters of Credit. In addition to the Company requesting that Lenders
make Revolving Loans pursuant to subsection 2.1A(iii) and that the Swing Line
Lender make Swing Line Loans pursuant to subsection 2.1A(iv), the Company may
request, in accordance with the provisions of this subsection 3.1, from time to
time during the period from the Closing Date to but excluding the date which is
five (5) Business Days before the Revolving Loan Commitment Termination Date,
that the Issuing Bank issue Letters of Credit for the account of the Company for
the purposes specified in the definitions of Commercial Letters of Credit and
Standby Letters of Credit. Subject to and upon the terms and conditions of this
Agreement and in reliance upon the representations and warranties of Loan
Parties herein set forth, the Issuing Bank agrees to issue such Letters of
Credit in accordance with the provisions of this subsection 3.1; provided that
the Company shall not request that the Issuing Bank issue (and the Issuing Bank
shall not issue):

            (i) any Letter of Credit if, after giving effect to such issuance,
      the Total Utilization of Revolving Loan Commitments would exceed the
      Revolving Loan Commitments then in effect;

            (ii) any Letter of Credit if, after giving effect to such issuance,
      the Letter of Credit Usage would exceed the Letter of Credit Subfacility
      Commitment;

            (iii) any Standby Letter of Credit having an expiration date later
      than the earlier of (a) five (5) Business Days prior to the Revolving Loan
      Commitment Termination Date and (b) the date which is one year from the
      date of issuance of such Standby Letter of Credit; provided, that the
      immediately preceding clause (b) shall not prevent the Issuing Bank from
      agreeing that a Standby Letter of Credit will automatically be extended
      for one or more successive periods absent a Default or Event of Default,
      subject to the immediately preceding clause (a), not to exceed one year
      each unless the Issuing Bank elects not to extend for any such additional
      period; provided, further, that, unless the Requisite Lenders otherwise
      consent, the Issuing Bank shall give notice that it will not extend such
      Standby Letter of Credit if it has knowledge that a Default or Event of
      Default has occurred and is continuing on the last day on which such
      Issuing Bank may give notice to the beneficiary that it will not extend
      such Standby Letter of Credit;


                                       66

<PAGE>

            (iv) any Commercial Letter of Credit (a) having an expiration date
      later than the earlier of (x) thirty (30) days prior to the Revolving Loan
      Commitment Termination Date and (y) the date which is one hundred eighty
      (180) days from the date of issuance of such Commercial Letter of Credit
      or (b) that is otherwise unacceptable to the Issuing Bank in its
      reasonable discretion;

            (v) any Letter of Credit denominated in a currency other than
      Dollars; or

            (vi) any Letter of Credit during any period when a Lender Default
      exists, unless the Issuing Bank has entered into arrangements satisfactory
      to it and the Company to eliminate the Issuing Bank's risk with respect to
      the Defaulting Lender, including by cash collateralizing such Defaulting
      Lender's Pro Rata Share of the Letter of Credit Usage (after giving effect
      to the issuance of the proposed Letter of Credit).

      B. Mechanics of Issuance.

            (i) Notice of Issuance. Whenever the Company desires the issuance of
      a Letter of Credit, it shall deliver to the Issuing Bank, at the Letter of
      Credit Issuing Office, and the Administrative Agent, at the Funding and
      Payment Office, a Notice of Issuance of Letter of Credit no later than
      12:00 Noon (New York time) at least five (5) Business Days, or such
      shorter period as may be agreed to by the Issuing Bank in any particular
      instance, in advance of the proposed date of issuance. The Notice of
      Issuance of Letter of Credit shall specify (a) the proposed date of
      issuance (which shall be a Business Day), (b) the face amount of or
      maximum aggregate liability under, as applicable, the Letter of Credit,
      (c) the expiration date of the Letter of Credit, (d) the name and address
      of the beneficiary, and (e) the verbatim text of the proposed Letter of
      Credit or the proposed terms and conditions thereof, including a precise
      description of any documents and the verbatim text of any certificates to
      be presented by the beneficiary which, if presented by the beneficiary
      prior to the expiration date of the Letter of Credit, would require the
      Issuing Bank to make payment thereunder; provided that the Issuing Bank,
      in its reasonable discretion, may require changes in the text of the
      proposed Letter of Credit or any such documents or certificates; provided
      further that no Letter of Credit shall require payment against a
      conforming draft or other request for payment to be made thereunder on the
      same business day (under the laws of the jurisdiction in which the office
      of the Issuing Bank to which such draft or other request for payment is
      required to be presented is located) that such draft or other request for
      payment is presented if such presentation is made after 10:00 A.M. (in the
      time zone of such office of the Issuing Bank) on such Business Day.

            The Company shall notify the Issuing Bank and the Administrative
      Agent prior to the issuance of any Letter of Credit in the event that any
      of the matters to which the Company is required to certify in the
      applicable Notice of Issuance of Letter of Credit is no longer true and
      correct as of the proposed date of issuance of such Letter of Credit, and
      upon the issuance of any Letter of Credit, the Company shall be deemed to
      have re-certified, as of the date of such issuance, as to the matters to
      which the Company is required to certify in the applicable Notice of
      Issuance of Letter of Credit.

            (ii) Issuance of Letter of Credit. Upon satisfaction or waiver (in
      accordance with subsection 10.6) of the conditions set forth in subsection
      4.3, the Issuing Bank shall issue the requested Letter of Credit in
      accordance with the Issuing Lender's standard procedures, and upon 


                                       67

<PAGE>

      its issuance of such Letter of Credit the Issuing Bank shall promptly
      notify the Administrative Agent and each Lender of such issuance, which
      notice shall be accompanied by a copy of such Letter of Credit.

            (iii) Reports to Lenders. Within thirty (30) days after the end of
      each calendar quarter ending after the Closing Date, so long as any Letter
      of Credit shall have been outstanding during such calendar quarter, the
      Issuing Bank shall deliver to the Administrative Agent and the
      Administrative Agent shall deliver to each Lender a report setting forth
      for such calendar quarter the daily maximum amount available to be drawn
      under the Letters of Credit that were outstanding during such calendar
      quarter.

      C. Lenders' Purchase of Participations in Letters of Credit. Immediately
upon the issuance of each Letter of Credit, each Lender shall be deemed to, and
hereby agrees to, have irrevocably purchased from the Issuing Bank a
participation in such Letter of Credit and any drawings honored or payments made
thereunder in an amount equal to such Lender's Pro Rata Share (with respect to
the Revolving Loan Commitments) of the maximum amount which is or at any time
may become available to be drawn or required to be paid thereunder.

3.2 Letter of Credit Fees.

      The Company agrees to pay the following amounts to the Issuing Bank with
respect to Letters of Credit issued by it for the account of the Company:

            (i) with respect to each Letter of Credit, (a) a fronting fee equal
      to 0.25% per annum of the daily maximum amount available to be drawn under
      such Letter of Credit and (b) a Letter of Credit fee equal to the product
      of (x) the then Applicable Eurodollar Rate Margin with respect to
      Revolving Loans and (y) the daily maximum amount available to be drawn
      under such Letter of Credit, in each case payable in arrears on and to the
      last Business Day in each of March, June, September and December of each
      year, commencing December 1998, and on the Revolving Loan Commitment
      Termination Date and computed on the basis of a 360-day year for the
      actual number of days elapsed; and

            (ii) with respect to the issuance, amendment or transfer of each
      Letter of Credit and each drawing made thereunder (without duplication of
      the fees payable under clause (i) above), documentary and processing
      charges in accordance with such Issuing Lender's standard schedule for
      such charges in effect at the time of such issuance, amendment, transfer
      or drawing, as the case may be.

Promptly upon receipt by such Issuing Bank of any amount described in clause
(i)(b) of this subsection 3.2, such Issuing Bank shall distribute to each other
Lender having Revolving Loan Exposure its Pro Rata Share of such amount.

3.3 Drawings and Payments and Reimbursement of Amounts Drawn or Paid Under
    Letters of Credit.

      A. Responsibility of Issuing Bank With Respect to Requests For Drawings
and Payments. In determining whether to honor any drawing or request for payment
under any Letter of Credit by the beneficiary thereof, the Issuing Bank shall be
responsible only to determine that the 


                                       68

<PAGE>

documents and certificates required to be delivered under such Letter of Credit
have been delivered and that they comply on their face with the requirements of
such Letter of Credit.

      B. Reimbursement by the Company of Amounts Drawn or Paid Under Letters of
Credit. In the event an Issuing Bank has determined to honor a drawing or
request for payment under a Letter of Credit issued by it, the Issuing Bank
shall immediately notify the Company and the Administrative Agent, and the
Company shall reimburse such Issuing Bank on or before the Business Day on which
such drawing is honored or such payment is made (the applicable "Reimbursement
Date") in an amount in same day funds equal to the amount of such honored
drawing; provided that, anything contained in this Agreement to the contrary
notwithstanding, (i) unless the Company shall have notified the Administrative
Agent and the Issuing Bank prior to 12:00 Noon (New York time) on the date of
such honored drawing or request for payment that the Company intends to
reimburse such Issuing Bank for the amount of such honored drawing or payment
with funds other than the proceeds of Revolving Loans, the Company shall be
deemed to have given a timely Notice of Borrowing to the Administrative Agent
requesting the Lenders to make Revolving Loans which are Base Rate Loans on the
applicable Reimbursement Date in an amount equal to the amount of such honored
drawing or payment and (ii) subject to satisfaction or waiver of the conditions
specified in subsection 4.2B, the Lenders shall, on the applicable Reimbursement
Date, make Revolving Loans in the amount of such honored drawing or payment, the
proceeds of which shall be applied directly by the Administrative Agent to
reimburse the Issuing Bank for the amount of such honored drawing or payment;
provided further that if for any reason proceeds of Revolving Loans are not
received by the Issuing Bank on the applicable Reimbursement Date in an amount
equal to the amount of such honored drawing or payment, the Company shall
reimburse the Issuing Bank, on demand, in an amount in same day funds equal to
the excess of the amount of such honored drawing or payment over the aggregate
amount of such Revolving Loans, if any, which are so received. Nothing in this
subsection 3.3B shall be deemed to relieve any Lender from its obligation to
make Revolving Loans on the terms and conditions set forth in this Agreement,
and the Company shall retain any and all rights it may have against any Lender
resulting from the failure of such Lender to make such Revolving Loans under
this subsection 3.3B.

      C. Payment by Lenders of Unreimbursed Drawings or Payments Under Letters
of Credit.

            (i) Payment by Lenders. In the event that the Company shall fail for
      any reason to reimburse any Issuing Bank as provided in subsection 3.3B in
      an amount equal to the amount of any honored drawing or payment made by
      such Issuing Bank under a Letter of Credit issued by it, such Issuing Bank
      shall promptly notify each other Lender of the unreimbursed amount of such
      honored drawing or payment and of such other Lender's respective
      participation therein based on such Lender's Pro Rata Share of the
      Revolving Loan Commitments. Each Lender shall make available to such
      Issuing Bank an amount equal to its respective participation, in same day
      funds, at the office of such Issuing Bank specified in such notice, not
      later than 2:00 P.M. (New York time) on the first business day (under the
      laws of the jurisdiction in which such office of such Issuing Bank is
      located) after the date notified by such Issuing Bank. In the event that
      any Lender fails to make available to such Issuing Bank on such business
      day the amount of such Lender's participation in such Letter of Credit as
      provided in this subsection 3.3C, such Issuing Bank shall be entitled to
      recover such amount on demand from such Lender together with interest
      thereon at the rate customarily used by such Issuing Bank for the
      correction of errors among banks for three Business Days and thereafter at
      the Base Rate. Nothing in this subsection 3.3C shall be deemed to
      prejudice the right of any Lender to recover from any Issuing Bank any
      amounts made available 


                                       69

<PAGE>

      by such Lender to such Issuing Bank pursuant to this subsection 3.3C in
      the event that it is determined by the final judgment of a court of
      competent jurisdiction that the payment with respect to a Letter of Credit
      by such Issuing Bank in respect of which payment was made by such Lender
      constituted gross negligence or willful misconduct on the part of such
      Issuing Bank.

            (ii) Distribution to Lenders of Reimbursements Received From the
      Company. In the event any Issuing Bank shall have been reimbursed by other
      Lenders pursuant to subsection 3.3C(i) for all or any portion of any
      honored drawing or payment made by such Issuing Bank under a Letter of
      Credit issued by it, such Issuing Bank shall distribute to each other
      Lender which has paid all amounts payable by it under subsection 3.3C(i)
      with respect to such honored drawing or payment such other Lender's Pro
      Rata Share of all payments subsequently received by such Issuing Bank from
      the Company in reimbursement of such honored drawing or payment when such
      payments are received. Any such distribution shall be made to a Lender at
      its primary address set forth below its name on the appropriate signature
      page hereof or at such other address as such Lender may request.

      D. Interest on Amounts Drawn or Paid Under Letters of Credit.

            (i) Payment of Interest by the Company. The Company agrees to pay to
      each Issuing Bank, with respect to drawings or payments made under any
      Letters of Credit issued by it, interest on the amount paid by such
      Issuing Bank in respect of each such drawing or payment from the date such
      drawing is honored or payment is made to but excluding the date such
      amount is reimbursed by the Company (including any such reimbursement out
      of the proceeds of Revolving Loans pursuant to subsection 3.3B) at a rate
      equal to (a) for the period from the date such drawing is honored or

      which it accrues and shall be payable on demand or, if no demand is made,
      on the date on which the related drawing or payment under a Letter of
      Credit is reimbursed in full.

            (ii) Distribution of Interest Payments by Issuing Bank. Promptly

      the period from the date of the applicable honored drawing or payment
      under a Letter of Credit issued by such Issuing Bank to but excluding the
      date on which such Issuing Bank is reimbursed for the amount of such
      drawing or payment (including any such reimbursement out of the proceeds
      of Revolving Loans pursuant to subsection 3.3B), the amount that such
      other Lender would have been entitled to receive in respect of the Letter
      of Credit fee that would have been payable in respect of such Letter of
      Credit for such period pursuant to subsection 3.2 if no drawing had been
      honored or payment had been made under such Letter of Credit, and (b) in
      the event such Issuing Bank shall have been reimbursed by other Lenders
      pursuant to subsection 3.3C(i) for all or any portion of such drawing or
      payment, such Issuing Bank shall distribute to each other Lender which has
      paid all amounts payable by it under subsection 3.3C(i) with respect to
      such drawing or payment such other Lender's Pro Rata Share of any interest
      received by such Issuing Bank in respect of that portion of such drawing
      or payment so reimbursed by other Lenders for the period from the date on
      which such Issuing Bank was so reimbursed by other Lenders to and
      including the date on 


                                       70

<PAGE>

      Company. Any such distribution shall be made to a Lender at its Lending
      Office set forth on Schedule 2.1 or at such other address as such Lender
      may request.

3.4 Obligations Absolute.

      The obligation of the Company to reimburse each Issuing Bank for drawings
honored or payments made under the Letters of Credit issued by it and to repay
any Revolving Loans made by the Lenders pursuant to subsection 3.3B and the
obligations of the Lenders under subsection 3.3C(i) shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances including, without limitation, the following
circumstances:

            (i) any lack of validity or enforceability of any Letter of Credit;

            (ii) the existence of any claim, set-off, defense or other right
      which the Company or any Lender may have at any time against a beneficiary
      or any transferee of any Letter of Credit (or any Persons for whom any
      such transferee may be acting), any Issuing Bank or other Lender or any
      other Person or, in the case of a Lender, against the Company whether in
      connection with this Agreement, the transactions contemplated herein or
      any unrelated transaction (including any underlying transaction between
      the Company or one of its Subsidiaries and the beneficiary for which any
      Letter of Credit was procured);

            (iii) any draft, demand, certificate or other document presented
      under any 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) payment by the applicable Issuing Bank under any Letter of
      Credit against presentation of a demand, draft or certificate or other
      document which appears to substantially comply with the terms of such
      Letter of Credit;

            (v) any adverse change in the business, operations, properties,
      assets, condition (financial or otherwise) or prospects of the Company or

      party thereto;

            (vii) any other circumstance or happening whatsoever, whether or not
      similar to any of the foregoing; or

            (viii) the fact that Default or Event of Default shall have occurred
      and be continuing;

provided, in each case, that payment by the applicable Issuing Bank under the
applicable Letter of Credit shall not have constituted gross negligence or
willful misconduct of such Issuing Bank under the circumstances in question (as
determined by a final judgment of a court of competent jurisdiction).

3.5 Indemnification; Nature of Issuing Lender's Duties.

      A. Indemnification. In addition to amounts payable as provided in
subsection 3.6, the Company hereby agrees to protect, indemnify, pay and save
harmless each Issuing Bank from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including 


                                       71

<PAGE>

reasonable fees, expenses and disbursements of counsel and allocated costs of
internal counsel) which such Issuing Bank may incur or be subject to as a
consequence, direct or indirect, of (i) the issuance of any Letter of Credit by
such Issuing Bank, other than as a result of (a) the gross negligence or willful
misconduct of such Issuing Bank as determined by a final judgment of a court of
competent jurisdiction or (b) subject to the following clause (ii), the wrongful
dishonor by such Issuing Bank of a proper demand for payment made under any
Letter of Credit issued by it or (ii) the failure of such Issuing Bank to honor
a drawing or other request for payment under any such Letter of Credit as a
result of any act or omission, whether rightful or wrongful, of any present or
future de jure or de facto government or governmental authority (all such acts
or omissions herein called "Governmental Acts").

      B. Nature of Issuing Bank's Duties. As between the Company and any Issuing
Bank, the Company assumes all risks of the acts and omissions of, or misuse of
the Letters of Credit issued by such Issuing Bank by, the respective
beneficiaries of such Letters of Credit. In furtherance and not in limitation of
the foregoing, such Issuing Bank shall not be responsible for: (i) the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
any such Letter of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) failure of the beneficiary of
any such Letter of Credit to comply fully with any conditions required in order
to draw upon such Letter of Credit; (iv) errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex or otherwise, whether or not they be in cipher; (v) errors in
interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any such
Letter of Credit or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing or
payment under such Letter of Credit; or (viii) any consequences arising from
causes beyond the control of such Issuing Bank, including without limitation any
Governmental Acts, and none of the above shall affect or impair, or prevent the
vesting of, any of such Issuing Lender's rights or powers hereunder.

      In furtherance and extension and not in limitation of the specific
provisions set forth in the first paragraph of this subsection 3.5B, any action
taken or omitted by any Issuing Bank under or in connection with the Letters of
Credit issued by it or any documents and certificates delivered thereunder, if
taken or omitted in good faith, shall not put such Issuing Bank under any
resulting liability to the Company.

      Notwithstanding anything to the contrary contained in this subsection 3.5,
the Company shall retain any and all rights it may have against any Issuing Bank
for any liability arising solely out of the gross negligence or willful
misconduct of such Issuing Bank, as determined by a final judgment of a court of
competent jurisdiction.

3.6 Increased Costs and Taxes Relating to Letters of Credit.

      In the event that any Issuing Bank or any Lender shall determine (which
determination shall, absent manifest error, be final and conclusive and binding
upon all parties hereto) that any law, treaty or governmental rule, regulation
or order, or any change therein or in the interpretation, administration or
application thereof (including the introduction of any new law, treaty or
governmental rule, regulation or order), or any determination of a court or
governmental authority, in each case that becomes effective after the Closing
Date, or compliance by any Issuing Bank or Lender with any guideline, request or


                                       72

<PAGE>

directive issued or made after the Closing Date by any central bank or other
governmental or quasi-governmental authority (whether or not having the force of
law):

            (i) results in any change in the basis of taxation of such Issuing
      Bank or any Lender (or its applicable lending or letter of credit office)
      (other than a change with respect to any Tax on the overall net income of
      such Issuing Bank or Lender) with respect to the issuing or maintaining of
      any Letters of Credit or the purchasing or maintaining of any
      participations therein or any other obligations under this Section 3,
      whether directly or by such being imposed on or suffered by any particular
      Issuing Bank;

            (ii) imposes, modifies or holds applicable any reserve (including
      without limitation any marginal, emergency, supplemental, special or other
      reserve), special deposit, compulsory loan, FDIC insurance or similar
      requirement in respect of any Letters of Credit issued by any Issuing Bank
      or participations therein purchased by any Lender; or

            (iii) imposes any other condition on or affecting such Issuing Bank
      or Lender (or its applicable lending or letter of credit office) regarding
      this Section 3 or any Letter of Credit or any participation therein;

and the result of any of the foregoing is to increase the cost to such Issuing
Bank or Lender of agreeing to issue, issuing or maintaining any Letter of Credit
or agreeing to purchase, purchasing or maintaining any participation therein or
to reduce any amount received or receivable by such Issuing Bank or Lender (or
its applicable lending or letter of credit office) with respect thereto; then,
in any case, the Company shall promptly pay to such Issuing Bank or Lender, upon
receipt of the statement referred to in the next sentence, such additional
amount or amounts (reasonably determined by such Issuing Bank or Lender) as may
be necessary to compensate such Issuing Bank or Lender for any such increased
cost or reduction in amounts received or receivable hereunder. Such Issuing Bank
or Lender shall deliver to the Company a written statement, setting forth in
reasonable detail the basis for calculating the additional amounts owed to such
Issuing Bank or Lender under this subsection 3.6, which statement shall be
conclusive and binding upon all parties hereto absent manifest error.

                                   SECTION 4.

reasonable and attainable.

or evidences or could reasonably be expected to cause, either individually or in
the aggregate, a Material Adverse Effect. Since December 31, 1997, neither the
Company nor any of its Subsidiaries has directly or indirectly declared,

      A. Title to Properties; Liens. After giving effect to the transactions
contemplated hereby and by the other Transaction Documents to occur on the

simple to or a valid leasehold interest in all of their respective properties
and assets reflected in the financial statements referred to in subsection 5.3
or in the most recent financial statements delivered pursuant to subsection 6.1,
except for assets disposed of since the date of such financial statements in the
ordinary course of business or as otherwise permitted under subsection 7.7 and
except for such defects that neither individually nor in the aggregate could
reasonably be expected to have a Material Adverse Effect. Except as permitted by
this Agreement, all such properties and assets are free and clear of Liens.

      B. Real Property. As of the Closing Date, Schedule 5.5B annexed hereto
contains a true, accurate and complete list of (i) all fee interests of any Loan
Party in real property and the Loan Party which owns such fee interest and (ii)
all Leasehold Properties of any Loan Party. Except as specified in Schedule 5.5B
annexed hereto, each lease or sublease, as applicable, for each such Leasehold
Property is in full force and effect and the Company does not have knowledge of
any material default by any party thereto that has occurred and is continuing
thereunder, and each such agreement constitutes the legally valid and binding
obligation of each applicable Loan Party, enforceable against such Loan Party in
accordance with its terms, except as enforcement may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to or limiting
creditors' rights generally or by equitable principles.

      C. Intellectual Property. The Company and its Subsidiaries own or have the

valid and enforceable. The conduct of the Company's and its Subsidiaries'
business as currently conducted, including, but not limited to, all products,
processes or services, made, offered or sold by the Company and its
Subsidiaries, does not infringe upon, violate, misappropriate or dilute any
intellectual property of any third party which infringement, violation,
misappropriation or dilution could reasonably be expected to have a Material
Adverse Effect. To the best of the Company's and its Subsidiaries' knowledge, no
third party is infringing upon the Intellectual Property in any material
respect. Except as set forth in Schedule 5.5C, there is no pending or to the
best of the Company's and its Subsidiaries' knowledge, threatened claim or
litigation contesting the Company's right to own or use any material
Intellectual Property or the validity or enforceability thereof.

      A. Neither the Parent, the Company nor any of its Subsidiaries is in
default in the performance, observance or fulfillment of any of the obligations,
covenants or conditions contained in any of its Contractual Obligations, and no
condition exists that, with the giving of notice or the lapse of time or both,
would constitute such a default, except, in each case, individually or in the
aggregate, where the consequences, direct or indirect, of such default or
defaults, if any, would not have a Material Adverse Effect. Each State Contract
in effect as of the Closing Date after giving effect to the Transactions is
listed on Schedule 5.8 annexed hereto.

      B. Neither the Parent, the Company nor any of its Subsidiaries is a party
to or is otherwise subject to any agreement or instrument or any charter or

regulation under the Public Utility Holding Company Act of 1935, the Federal

principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any Margin Stock.

5.11 Employee Benefit Plans.

      A. Schedule 5.11 annexed hereto sets forth a list of each Pension Plan,
Multiemployer Plan, 


                                       87

<PAGE>

and each "welfare plan" (as defined in Section 3(1) of ERISA) which provides
post-retirement benefits other than benefits as required under Part 6 of Title I
of ERISA. The Company and each of its ERISA Affiliates are in compliance with
all applicable provisions and requirements of ERISA with respect to each
Employee Benefit Plan, and have performed all their obligations under each
Employee Benefit Plan, except to the extent that any non-compliance with ERISA
or any such failure to perform would not have a Material Adverse Effect on the
Company or any of its ERISA Affiliates. No material liability to the PBGC (other
than required premium payments), the Internal Revenue Service, any Plan or any
trust established under Title IV of ERISA has been, or is expected by the
Company or any of its ERISA Affiliates to be, incurred by the Company or any of
its ERISA Affiliates.

      B. No ERISA Event has occurred which has resulted or is reasonably likely
to result in any material liability of the Company or any of its ERISA

Revenue Code and/or Section 601 of ERISA, neither the Company nor any of its
Subsidiaries maintains or contributes to any employee welfare benefit plan (as

employees of the Company or any of its Subsidiaries other than as set forth on
Schedule 5.11 annexed hereto.

      D. No Pension Plan has an Unfunded Current Liability in an amount that
would have a Material Adverse Effect.

      E. The Borrower and each or its ERISA Affiliates have complied with the
requirements of Section 515 of ERISA with respect to each Multiemployer Plan and
is not in "default" (as defined in Section 4219(c)(5) of ERISA) with respect to
payments to a Multiemployer Plan, except to the extent that such non-compliance
therewith or default would not, either individually or in the aggregate, have a
Material Adverse Effect. As of the most recent valuation date for each
Multiemployer Plan for which the actuarial report is available, the potential
liability of the Company, its Subsidiaries and their respective ERISA Affiliates
for a complete withdrawal from such Multiemployer Plan (within the meaning of
Section 4203 of ERISA), when aggregated with such potential liability for a
complete withdrawal from all Multiemployer Plans, based on information available
pursuant to Section 4221(e) of ERISA, could not reasonably be expected to have a
Material Adverse Effect.

5.12 Certain Fees.

      No broker's or finder's fee or commission will be payable with respect to
this Agreement or any of the loan transactions contemplated hereby, and the
Company hereby indemnifies the Lenders against, and agrees that it will hold the

      the knowledge of the Company (after due inquiry), each of the tenants
      under any leases or occupancy agreements affecting any portion of any
      Facilities presently owned 


                                       88

      applicable Environmental Laws (which compliance includes, but is not
      limited to, the possession by the Company, each of its Subsidiaries and
      each of such tenants of all permits and other Governmental Authorizations
      required under applicable Environmental Laws, and compliance with the
      terms and conditions thereof), except where failure to be in compliance
      would not have a Material Adverse Effect. Neither the Company nor any of
      its Subsidiaries, nor, to the knowledge of the Company (after due

      the best knowledge of the Company, future) actions, activities,
      circumstances conditions, events or incidents that may prevent or
      interfere with such compliance in the future.

      Company, against any Person whose liability for any Environmental Claim
      the Company or any of its Subsidiaries has or may have retained or assumed
      either contractually or by operation of law, in each such case which,
      individually or in the aggregate, would have a Material Adverse Effect.

            (iii) There are no past or present (or to the best knowledge of the
      Company, future) actions, activities, circumstances, conditions, events or
      incidents, including, without limitation, the Release or presence of any
      Hazardous Material, which could reasonably be expected to form the basis
      of any Environmental Claim against the Company or any of its Subsidiaries,
      or to the best knowledge of the Company, against any Person whose
      liability for any Environmental Claim the Company or any of its
      Subsidiaries has or may have retained or assumed either contractually or
      by operation of law, in each such case which would have a Material Adverse
      Effect.

            (iv) The Company and its Subsidiaries have not, and to the best
      knowledge of the Company, no other Person has placed, stored, deposited,
      discharged, buried, dumped or disposed of Hazardous Materials or any other
      wastes produced by, or resulting from, any business, commercial or
      industrial activities, operations or processes, on, beneath or adjacent to
      any property currently or formerly owned, operated or leased by the
      Company or any of its Subsidiaries, except for inventories of such
      substances to be used, and wastes generated therefrom, in the ordinary
      course of business of the Company and its Subsidiaries (which inventories
      and wastes, if any, were and are stored or disposed of in accordance with
      applicable Environmental Laws and in a manner such that there has been no
      Release of any such substances), in each case, which, individually or in
      the aggregate, would have a Material Adverse Effect.

            (v) No Lien in favor of any Person relating to or in connection with
      any Environmental Claim has been filed or has been attached to any
      Facility.

            (vi) Without in any way limiting the generality of the foregoing,
      except as would not have a Material Adverse Effect, none of the Facilities
      contain any: underground storage tanks; asbestos; polychlorinated
      biphenyls ("PCBs"); underground injection wells; radioactive materials; or
      septic tanks or waste disposal pits in which process wastewater or any
      Hazardous Materials have been discharged or disposed.

6.2 Corporate Existence

      Except as permitted under subsection 7.7, the Parent and the Company will,
and will cause each of its Subsidiaries to, at all times preserve and keep in
full force and effect its corporate existence and all rights and franchises
material to the business of the Company and its Subsidiaries (on a consolidated
basis) or the Loan Parties, taken as a whole.

6.3 Payment of Taxes and Claims; Tax Consolidation.

      A. The Parent and the Company will, and will cause each of its
Subsidiaries to, pay all taxes, assessments and other governmental charges
imposed upon it or any of its properties or assets or in respect 


                                       97

<PAGE>

of any of its income, businesses or franchises before any penalty accrues
thereon, and all claims (including, without limitation, claims for labor,
services, materials and supplies) for sums that have become due and payable
which, if unpaid, might become a Lien (other than a Permitted Encumbrance) upon
any of its properties or assets; provided that no such tax, charge or claim need
be paid if being contested in good faith by appropriate proceedings promptly
instituted and diligently conducted and if such reserve or other appropriate
provision, if any, as shall be required in conformity with GAAP shall have been
made therefor.

      B. The Parent and the Company will not, nor will it permit any of its
Subsidiaries to, file or consent to the filing of any consolidated, combined or
other similar income tax return with any Person (other than the Parent, the
Company and Subsidiaries of the Company).

6.4 Maintenance of Properties; Insurance.

      The Company will, and will cause each of its Subsidiaries to, maintain or
cause to be maintained in good repair, working order and condition, ordinary
wear and tear excepted, all material properties used or useful in the business
of the Company and its Subsidiaries and from time to time will make or cause to
be made all appropriate repairs, renewals and replacements thereof. The Company
will maintain or cause to be maintained, with financially sound and reputable
insurers, insurance with respect to its properties and business and the
properties and businesses of its Subsidiaries against loss or damage of the
kinds and with respect to liability customarily carried or maintained under
similar circumstances by corporations of established reputation engaged in
similar businesses. Each such policy of casualty insurance covering damage to or
loss of property (other than property of any Foreign Subsidiary that is not a
Foreign Subsidiary Guarantor) shall name the Collateral Agent for the benefit of
the Lenders as additional insured and as the loss payee thereunder for all
losses, subject to application of proceeds as required by subsection
2.4B(iii)(d), each such policy of liability insurance coverage shall name each
of the Lenders and Agents as additional insureds, and all such policies of
insurance shall provide for at least thirty (30) days' prior written notice to
the Collateral Agent of any modification or cancellation of such policy.

6.5 Inspection; Lender Meeting.

      Each of the Parent and the Company shall, and shall cause each of its
Subsidiaries to, permit the Administrative Agent and (unless a Default or Event
of Default has occurred and is continuing, at the expense of the applicable
Lender) any authorized representatives designated by any Lender to visit and
inspect any of the properties of the Parent, the Company or any of the Company's
Subsidiaries, including its and their financial and accounting records, and to
make copies and take extracts therefrom, and to discuss its and their affairs,
finances and accounts with its and their officers and independent public
accountants, all upon reasonable advance notice and at such reasonable times
during normal business hours and as often as may be reasonably requested.
Without in any way limiting the foregoing, the Company will, upon the request of
the Administrative Agent, participate in a meeting of the Administrative Agent
and the Lenders once during each Fiscal Year to be held at the Company's
corporate offices (or such other location as may be agreed to by the Company and
the Administrative Agent) at such time as may be agreed to by the Company and
the Administrative Agent.

6.6 Compliance with Laws, etc.

      The Parent and the Company shall, and shall cause each of its Subsidiaries
to, comply with the requirements of all applicable laws, rules, regulations and
orders of any governmental authority, 


                                       98

<PAGE>

noncompliance with which, individually or in the aggregate with other
non-compliances, could reasonably be expected to cause a Material Adverse
Effect.

6.7 Environmental Disclosure and Inspection.

      A. The Company shall, and shall cause each of its Subsidiaries to,
exercise all due diligence in order to comply and cause (i) all tenants under
any leases or occupancy agreements affecting any portion of the Facilities
presently owned or operated by the Company or its Subsidiaries and (ii) all
other Persons on or occupying such property, to comply with all Environmental
Laws, noncompliance with which could reasonably be expected to cause a Material
Adverse Effect.

      B. The Company agrees that the Administrative Agent may, from time to
time, retain, at the Company's expense, an independent professional consultant
reasonably acceptable to the Company to review any report relating to Hazardous
Materials prepared by or for the Company and to conduct its own investigation of
any Facility currently owned, leased, operated or used by the Company or any of
its Subsidiaries, if (x) a Default or an Event of Default shall have occurred
and be continuing, or (y) the Administrative Agent reasonably believes (1) that
an occurrence relating to such Facility is likely to give rise to an
Environmental Liability or (2) that a violation of an Environmental Law on or
around such Facility has occurred or is likely to occur, which could, in either
such case, reasonably be expected to result in a Material Adverse Effect. The
Company agrees to use all reasonable efforts to obtain permission for the
Administrative Agent's professional consultant to conduct its own investigation
of any such Facility previously owned, leased, operated or used by the Company
or any of its Subsidiaries. The Company shall use its reasonable efforts to
obtain for the Administrative Agent and its agents, employees, consultants and
contractors the right, upon reasonable notice to the Company, to enter into or
on to the Facilities currently owned, leased, operated or used by the Company or
any of its Subsidiaries to perform such tests on such property as are reasonably
necessary to conduct such a review and/or investigation. Any such investigation
of any Facility shall be conducted, unless otherwise agreed to by the Company
and the Administrative Agent, during normal business hours and, to the extent
reasonably practicable, shall be conducted so as not to interfere with the
ongoing operations at any such Facility or to cause any damage or loss to any
property at such Facility. The Company and the Administrative Agent hereby
acknowledge and agree that any report of any investigation conducted at the
request of the Administrative Agent pursuant to this subsection 6.7B will be
obtained and shall be used by the Administrative Agent and the Lenders for the
purposes of the Lenders' internal credit decisions, to monitor and police the
Loans and to protect the Lenders' security interests, if any, created by the
Loan Documents, and the Administrative Agent and the Lenders hereby acknowledge
and agree any such report will be kept confidential by them to the extent
permitted by law except as provided in the following sentence. The
Administrative Agent agrees to deliver a copy of any such report to the Company
with the understanding that the Company acknowledges and agrees that (i) it will
indemnify and hold harmless the Administrative Agent and each Lender from any
costs, losses or liabilities relating to the Company's use of or reliance on
such report, (ii) neither Agent nor any Lender makes any representation or
warranty with respect to such report, and (iii) by delivering such report to the
Company, neither the Administrative Agent nor any Lender is requiring or
recommending the implementation of any suggestions or recommendations contained
in such report.

      C. The Company shall promptly advise the Administrative Agent in writing
and in reasonable detail of (i) any Release or threatened Release of any
Hazardous Materials required to be reported to any federal, state, local or
foreign governmental or regulatory agency under any applicable Environmental
Laws, (ii) any and all communications (written or 


                                       99

<PAGE>

oral) with respect to any pending or threatened Environmental Claims in each
such case which, individually or in the aggregate, have a reasonable possibility
of giving rise to a Material Adverse Effect or any and all material
communications (written or oral) with respect to any Release or threatened
Release of Hazardous Materials, (iii) any Cleanup performed by the Company or
any other Person in response to (x) any Hazardous Materials on, under or about
any Facility, the existence of which has a reasonable possibility of resulting
in an Environmental Liability having a Material Adverse Effect, or (y) any
Environmental Liabilities that could have a Material Adverse Effect, (iv) the
Company's discovery of any occurrence or condition on any property that could
cause any Facility presently owned or operated by the Company or its
Subsidiaries or any part thereof to be subject to any restrictions on the
ownership, occupancy, transferability or use thereof under any Environmental
Laws, and (v) any request for information from any governmental agency that
fairly suggests such agency is investigating whether the Company or any of its
Subsidiaries may be potentially responsible for a Release or threatened Release
of Hazardous Materials.

      D. The Company shall promptly notify the Administrative Agent of (i) any
proposed acquisition of stock, assets, or property by the Company or any of its
Subsidiaries that could reasonably be expected to expose the Company or any of
its Subsidiaries to, or result in, Environmental Liability that could have a
Material Adverse Effect or that could reasonably be expected to have a material
adverse effect on any Governmental Authorization then held by the Company or any
of its Subsidiaries and (ii) any proposed action to be taken by the Company or
any of its Subsidiaries to commence manufacturing, industrial or other similar
operations that could reasonably be expected to subject the Company or any of
its Subsidiaries to additional Environmental Laws, that are materially different
from the Environmental Laws applicable to the operations of the Company and its
Subsidiaries as of the Closing Date.

      E. The Company shall, at its own expense, provide copies of such documents
or information as the Administrative Agent may reasonably request in relation to
any matters disclosed pursuant to this subsection 6.7.

6.8 The Company's Remedial Action Regarding Hazardous Materials.

      The Company shall promptly take, and shall cause each of its Subsidiaries
promptly to take, any and all necessary remedial action in connection with the
presence, handling, storage, use, disposal, transportation or Release or
threatened Release of any Hazardous Materials on, under or affecting any
Facility in order to comply with all applicable Environmental Laws and
Governmental Authorizations unless the failure to so comply could not reasonably
be expected to have a Material Adverse Effect. In the event the Company or any
of its Subsidiaries undertakes any Cleanup action with respect to the presence,
Release or threatened Release of any Hazardous Materials on or affecting any
Facility, the Company or such Subsidiary shall conduct and complete such Cleanup
action in material compliance with all applicable Environmental Laws, and in
accordance with the policies, orders and directives of all federal, state and
local governmental authorities except when, and only to the extent that, the
Company's or such Subsidiary's liability for such presence, handling, storage,
use, disposal, transportation or Release or threatened Release of any Hazardous
Materials is being contested in good faith by the Company or such Subsidiary.

6.9 Execution of Guaranty and Collateral Documents by Future Subsidiaries.

      In the event that any Person becomes a Subsidiary of the Company
(including, without limitation, any Domestic Subsidiary created in accordance
with subsection 7.7(viii)), the Company will promptly notify the Administrative
Agent of that fact and, unless such Subsidiary is an Excluded Foreign Subsidiary
or an SPC, cause such Subsidiary on or prior to the time it becomes a Subsidiary
to execute and deliver to the Administrative Agent and the Collateral Agent a
counterpart of the Subsidiary and Parent Guaranty or 


                                      100

<PAGE>

the Foreign Subsidiary Guaranty, as the case may be, and the Pledge Agreement
and the Security Agreement or the Foreign Subsidiary Pledge Agreement and a
foreign law governed security agreement, as the case may be, and to take all
such further action and execute all such further documents and instruments as
may be required to grant and perfect in favor of the Collateral Agent, for the
benefit of the Lenders, a First Priority security interest in all of the real,
mixed and personal property assets of such Subsidiary; provided, that a Foreign
Subsidiary shall not be required to enter into any Loan Document and become a
Foreign Subsidiary Guarantor if either (x) the grant by such Foreign Subsidiary
of a Lien on all of its assets as security for the Obligations or (y) the
guaranteeing by such Foreign Subsidiary of the Obligations, or both, would in
the good faith reasonable judgment of the Company, result in adverse tax
consequences to the Company. In addition, the Company shall pledge (if it is the
direct owner of Capital Stock of such Subsidiary) or shall cause each of its
applicable Subsidiaries (other than a Foreign Subsidiary that is not a Foreign
Subsidiary Guarantor) to pledge (if any of such other Subsidiaries is the direct
owner of Capital Stock of such Subsidiary, each such owner, whether the Company
or any of its other Subsidiaries, the "Pledging Parent") all of the Capital
Stock of such Subsidiary, including any SPC (or 65% of such Capital Stock if
such Subsidiary is an Excluded Foreign Subsidiary or a Foreign Subsidiary which
is not required to be a Foreign Subsidiary Guarantor hereunder) to the
Collateral Agent pursuant to the applicable Collateral Documents and to take all
such further action and execute all such further documents and instruments as
may be required to grant and perfect in favor of the Collateral Agent, for the
benefit of the Lenders, a First Priority security interest in such Capital
Stock. The Company shall deliver to the Administrative Agent, together with such
Loan Documents, in the case of each such Subsidiary that is required to be a
party to any Loan Document: (i) (a) certified copies of such Subsidiary's
Organizational Certificate together, if applicable, with a good standing
certificate from the Secretary of State of the jurisdiction of its
incorporation, formation or organization, as applicable, each to be dated a
recent date prior to their delivery to the Administrative Agent, (b) a copy of
such Subsidiary's Organizational Documents, certified by its secretary or an
assistant corporate secretary (or Person holding an equivalent title or having
equivalent duties and responsibilities) as of a recent date prior to their
delivery to the Administrative Agent, (c) a certificate executed by the
secretary or an assistant secretary of such Subsidiary as to (x) the incumbency
and signatures of the officers of such Subsidiary executing such Guaranty, the

Subsidiary authorizing the execution, delivery and performance of such Guaranty,
such Collateral Documents and such other Loan Documents are in full force and
effect and have not been modified or rescinded, and (ii) a favorable opinion of
counsel to such Subsidiary, that is reasonably satisfactory to the Agents and
their counsel, as to (a) the due organization and good standing of such
Subsidiary, (b) the due authorization, execution and delivery by such Subsidiary
of such Guaranty, the Collateral Documents and any other Loan Documents to which
it is a party and (c) the enforceability of such Guaranty and such Collateral
Documents against such Subsidiary, (d) the validity and perfection of the
security interests granted by such Subsidiary (and by the Pledging Parent of
such Subsidiary in respect of the Capital Stock of such Subsidiary (including
each Foreign Subsidiary and SPC)) in favor of the Collateral Agent pursuant to
the Collateral Documents, and (e) such other matters as any Agent may reasonably
request, all of the foregoing to be reasonably satisfactory in form and
substance to the Administrative Agent, the Collateral Agent and their counsel.
In addition, the Company shall promptly deliver a supplement to Schedule 5.1 to
the Administrative Agent if any Subsidiary is created or acquired.

and substance satisfactory to the Administrative 


                                      101

<PAGE>

Agent to the extent necessary so that, at all times, interest on the portion of
the outstanding principal amount of Term Loans equal to at least 50% of the
aggregate outstanding principal amount of the Term Loans is covered by such
Interest Rate Agreements.

      E. Certain Calculations.

            (i) With respect to any period during which any Permitted
      Acquisition occurs or any business of any other Person is acquired by the
      Company or any of its Subsidiaries as permitted pursuant to the terms
      hereof, for purposes of determining compliance or Pro Forma Compliance
      with the financial covenants set forth in this subsection 7.6,
      Consolidated Adjusted EBITDA and Consolidated Interest Expense shall be
      calculated with respect to such periods and such Permitted Acquisition or
      business on a pro forma basis (including pro forma adjustments arising out
      of events which are directly attributable to a specific transaction, are
      factually supportable and are expected to have a continuing impact, in
      each case, determined on a basis consistent with Article 11 of Regulation
      S-X under the Securities Act, which pro forma adjustments shall be
      certified by the chief financial officer of the Company) using the
      historical financial statements of all entities or business so acquired or
      to be acquired and the consolidated financial statements of the Company
      and its Subsidiaries which shall be reformulated (a) as if such
      acquisition, and any acquisitions which have been consummated during such
      period, and any Indebtedness or other liabilities incurred in connection
      with any such acquisition, had been consummated or incurred at the
      beginning of such period (and assuming that such Indebtedness bears
      interest during any portion of the applicable measurement period prior to
      the relevant acquisition at the weighted average of the interest rates
      applicable to outstanding Loans during such period), and (b) otherwise in
      conformity with such procedures as may be agreed upon between the
      Administrative Agent and the Company, all such calculations to be in form
      and substance satisfactory to the Administrative Agent.

            (ii) With respect to any period during which any Subsidiary of the
      Company or any business of the Company or any of its Subsidiaries is sold
      or otherwise disposed of, for purposes of determining compliance with the
      financial covenants set forth in this subsection 7.6, Consolidated
      Adjusted EBITDA and Consolidated Interest Expense shall be calculated with
      respect to such periods and such Subsidiaries or businesses on a pro forma
      basis (including pro forma adjustments arising out of events which are
      directly attributable to a specific transaction, are factually supportable
      and are expected to have a continuing impact, in each case, determined on
      a basis consistent with Article 11 of Regulation S-X under the Securities
      Act, which pro forma adjustments shall be certified by the chief financial
      officer of the Company) using the consolidated financial statements of the
      Company and its Subsidiaries which shall be reformulated (a) as if such
      sale or disposition, and any sales or dispositions which have been
      consummated during such period, and any Indebtedness or other liabilities
      assumed by the acquirer thereof in connection 


                                      114

<PAGE>

      with any such sale or disposition, had been consummated or assumed at the
      beginning of such period, and (b) otherwise in conformity with such
      procedures as may be agreed upon between the Administrative Agent and the
      Company, all such calculations to be in form and substance satisfactory to
      the Administrative Agent.

      F. State Contract Terminations.

      On each date of the expiration, termination, cancellation, rescission or
other material adverse amendment or modification of any State Contract, the
Company shall be in Pro Forma Compliance, assuming, for purposes of the
foregoing, that (i) such expiration, termination, cancellation, rescission or
other material amendment or modification took effect as of the beginning of the
most recently completed Calculation Period, (ii) the Permitted Testing Center
Assets attributable to such State Contract and no longer useful in connection
therewith were sold at the beginning of such period at prices proposed by the
Company and agreed upon by the Administrative Agent (or, absent such agreement,
their respective net book values), (iii) the reasonably estimated net cash
proceeds of such sales, and any other payments received by the Company or any
Subsidiary Guarantor from any applicable Governmental Authority in connection
with any such termination, were used to repay outstanding Term A Loans (and
thereafter Term B Loans), or any other Indebtedness permitted hereby that is
secured by such Indebtedness, as of the beginning of such period, and (iv) any
price increases which became effective during such period under any then State
Contract became effective as of the beginning of such period. As promptly as
practicable after the occurrence of any such expiration, cancellation,
termination, rescission or other material amendment or modification, but in any
event within thirty (30) days thereof, the Company shall deliver to the
Administrative Agent an Officer's Certificate of the chief financial officer of
the Company demonstrating in reasonable detail whether the Company is in such
Pro Forma Compliance.

      property or assets may be conveyed, sold, leased, transferred or otherwise
      disposed of, in one transaction or a series of transactions, to the
      Company or any wholly-owned Subsidiary of its Related Subsidiary Group;
      provided that, in the case of such a merger involving the Company, the
      Company shall be the continuing or surviving corporation, in the case of
      any such merger involving a Domestic Subsidiary (but not the Company), a
      Domestic Subsidiary shall be the continuing or surviving corporation and
      in the case of any other such merger involving a Subsidiary Guarantor, a
      wholly-owned Subsidiary Guarantor shall be the continuing or surviving
      corporation;

Administrative Agent or the Collateral Agent, shall be held by the Collateral
Agent pursuant to the terms of the Collateral Account Agreement and shall be
applied as therein provided.

      Notwithstanding anything contained in the second preceding paragraph, if
at any time within sixty (60) days after an acceleration of the Loans pursuant
to such paragraph the Company shall pay all arrears of interest and all payments
on account of principal which shall have become due otherwise than as a result
of such acceleration (with interest on principal and, to the extent permitted by
law, on overdue interest, at the rates specified in this Agreement) and all
Defaults and Events of Default (other than non-payment of the principal of and
accrued interest on the Loans, in each case which is due and payable solely by
virtue of acceleration) shall be remedied or waived pursuant to subsection 10.6,
then the Requisite Lenders, by written notice to the Company, may at their
option rescind and annul such acceleration and its consequences; but such action
shall not affect any subsequent Default or Event of Default or impair any right
consequent thereon. The provisions of this paragraph are intended merely to bind
the Lenders to a decision which may be made at the election of the Requisite
Lenders and are not intended to benefit the Company and do not grant the Company
the right to require the Lenders to rescind or annul any acceleration hereunder
or preclude the Agents or the Lenders from exercising any of the rights or
remedies available to them under any of the Loan Documents, even if the
conditions set forth in this paragraph are met.

                                   SECTION 9.
                                     AGENTS

9.1 Appointment.

      A. CSFB is hereby appointed the Administrative Agent hereunder and under
the other Loan Documents. DLJ Capital is hereby appointed the Syndication Agent
hereunder and under the Loan Documents. CSFB is hereby appointed the Collateral
Agent hereunder and under the Collateral Documents. CSFB and DLJ Securities are
hereby appointed the Arrangers hereunder and under the Loan Documents. Each
Lender hereby authorizes each Agent to act as its agent in accordance with the
terms of 


                                      124

<PAGE>

this Agreement and the other Loan Documents. Each Agent agrees to act upon the
express conditions contained in this Agreement and the other Loan Documents, as
applicable. The provisions of this Section 9 are solely for the benefit of the
Agents and the Lenders and the Company shall have no rights as a third party
beneficiary of any of the provisions thereof. In performing its functions and
duties under this Agreement, each Agent shall act solely as an agent of the
Lenders and does not assume and shall not be deemed to have assumed any
obligation towards or relationship of agency or trust with or for the Company or
any of its Subsidiaries. Upon the conclusion of the Initial Period, all
obligations of the Arrangers hereunder shall terminate and thereafter, the
Arrangers shall have no obligations or liabilities under any of the Loan
Documents.

      B. Appointment of Supplemental Collateral Agents. It is the purpose of
this Agreement and the other Loan Documents that there shall be no violation of
any law of any jurisdiction denying or restricting the right of banking
corporations or associations to transact business as agent or trustee in such
jurisdiction. It is recognized that in case of litigation under this Agreement
or any of the other Loan Documents, and in particular in case of the enforcement
of any of the Loan Documents, or in case the Administrative Agent or the
Collateral Agent deems that by reason of any present or future law of any
jurisdiction the Administrative Agent or the Collateral Agent may not exercise
any of the rights, powers or remedies granted herein or in any of the other Loan
Documents or take any other action which may be desirable or necessary in
connection therewith, it may be necessary that the Administrative Agent or the
Collateral Agent appoint an additional individual or institution as a separate
trustee, co-trustee, collateral agent or collateral co-agent (any such
additional individual or institution being referred to herein individually as a
"Supplemental Collateral Agent" and collectively as "Supplemental Collateral
Agents").

      In the event that the Administrative Agent or the Collateral Agent
appoints a Supplemental Collateral Agent with respect to any Collateral, (i)
each and every right, power, privilege or duty expressed or intended by this
Agreement or any of the other Loan Documents to be exercised by or vested in or
conveyed to the Administrative Agent or the Collateral Agent with respect to
such Collateral shall be exercisable by and vest in such Supplemental Collateral
Agent to the extent, and only to the extent, necessary to enable such
Supplemental Collateral Agent to exercise such rights, powers and privileges
with respect to such Collateral and to perform such duties with respect to such
Collateral, and every covenant and obligation contained in the Loan Documents
and necessary to the exercise or performance thereof by such Supplemental
Collateral Agent shall run to and be enforceable by either the Administrative
Agent or the Collateral Agent or such Supplemental Collateral Agent, and (ii)
the provisions of this Section 9 and of subsections 10.2 and 10.3 that refer to
the Administrative Agent or the Collateral Agent shall inure to the benefit of
such Supplemental Collateral Agent and all references therein to the
Administrative Agent or the Collateral Agent shall be deemed to be references to
the Administrative Agent or the Collateral Agent and/or such Supplemental
Collateral Agent, as the context may require.

      Should any instrument in writing from the Company or any other Loan Party
be required by any Supplemental Collateral Agent so appointed by the
Administrative Agent or the Collateral Agent for more fully and certainly
vesting in and confirming to him or it such rights, powers, privileges and
duties, the Company shall, or shall cause such Loan Party to, execute,
acknowledge and deliver any and all such instruments promptly upon request by
the Administrative Agent or the Collateral Agent. In case any Supplemental
Collateral Agent, or a successor thereto, shall die, become incapable of acting,
resign or be removed, all the rights, powers, privileges and duties of such
Supplemental Collateral Agent, to the extent permitted by law, shall vest in and
be exercised by the Administrative Agent or the Collateral Agent until the
appointment of a new Supplemental Collateral Agent.

9.2 Powers; General Immunity.

      A. Duties Specified. Each Lender irrevocably authorizes each Agent to take
such action on such Lender's behalf and to exercise such powers hereunder and
under the other Loan Documents as are specifically delegated to such Agent by
the terms hereof and thereof, together with such powers as are reasonably
incidental thereto. Each Agent shall have only those duties and responsibilities
that are expressly specified in this Agreement and the other Loan Documents and
it may perform such duties by or through its agents or employees. No Agent shall
have, by reason of this Agreement or any of the other Loan Documents, a
fiduciary relationship in respect of any Lender; and nothing in this Agreement
or any of the other Loan Documents, expressed or implied, is intended to or
shall be so construed as to impose upon any Agent any obligations in respect of
this Agreement or any of the other Loan Documents except as expressly set forth
herein or therein.

      B. No Responsibility for Certain Matters. No Agent shall be responsible to
any Lender for the execution, effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Agreement or any other
Loan Document or for any representations, warranties, recitals or statements
made herein or therein or made in any written or oral statement or in any
financial or other statements, instruments, reports or certificates or any other
documents furnished by any Agent to the Lenders or by or on behalf of the
Company and/or its Subsidiaries to any Agent or any Lender in connection with
the Loan Documents and the transactions contemplated thereby or for the
financial condition or business affairs of the Company or any other Person
liable for the payment of any Obligations, nor shall any Agent be required to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained in any of the Loan
Documents or as to the use of the proceeds of the Loans or the use of the
Letters of Credit or as to the existence or possible existence of any Default or
Event of Default. Anything contained in this Agreement to the contrary
notwithstanding, the Administrative Agent shall not have any liability arising
from confirmations of the amount of outstanding Loans or the Total Utilization
of Revolving Loan Commitments or the component amounts thereof.

      C. Exculpatory Provisions. Neither any Agent nor any of such Agent's
respective officers, directors, employees or agents shall be liable to the
Lenders for any action taken or omitted by such Agent under or in connection
with any of the Loan Documents except to the extent caused by such Agent's gross
negligence or willful misconduct. If any Agent shall request instructions from
the Lenders with respect to any act or action (including the failure to take an
action) in connection with this Agreement or any of the other Loan Documents,
such Agent shall be entitled to refrain from such act or taking such action
unless and until such Agent shall have received instructions from the Requisite
Lenders (or such other Lenders as may be required to give such instructions
under subsection 10.6). Without prejudice to the generality of the foregoing,
(i) such Agent shall be entitled to rely, and shall be fully protected in
relying, upon any communication, instrument or document believed by it to be
genuine and correct and to have been signed or sent by the proper person or
persons, and shall be entitled to rely and shall be protected in relying on
opinions and judgments of attorneys (who may be attorneys for the Company and
its Subsidiaries), accountants, experts and other professional advisors selected
by it; and (ii) no Lender shall have any right of action whatsoever against such
Agent as a result of such Agent acting or (where so instructed) refraining from
acting under this Agreement or any of the other Loan Documents in accordance
with the instructions of the Requisite Lenders (or such other Lenders as may be
required to give such instructions under subsection 10.6). Such Agent shall be
entitled to refrain from exercising any power, discretion or authority vested in
it under this Agreement or any of the other Loan Documents unless and until it
has obtained the instructions of the Requisite Lenders (or such other Lenders as
may be required to give such


                                      126

<PAGE>

instructions under subsection 10.6).

      D. Agents Entitled to Act as the Lender. The agency hereby created shall
in no way impair or affect any of the rights and powers of, or impose any duties
or obligations upon, any Agent in its individual capacity as a Lender hereunder.
With respect to its participation in the Loans and the Letters of Credit, each
Agent shall have the same rights and powers hereunder as any other Lender and
may exercise the same as though it were not performing the duties and functions
delegated to it hereunder, and the term "Lender" or "Lenders" or any similar
term shall, unless the context clearly otherwise indicates, include such Agent
in its individual capacity. Each Agent and its Affiliates may accept deposits
from, lend money to and generally engage in any kind of banking, trust,
financial advisory or other business with the Company or any of its Affiliates
as if it were not performing the duties specified herein, and may accept fees
and other consideration from the Company and/or its Subsidiaries for services in
connection with this Agreement and otherwise without having to account for the
same to the Lenders.

9.3 Representations and Warranties; No Responsibility For Appraisal of
    Creditworthiness.

      Each Lender represents and warrants that it has made its own independent
investigation of the financial condition and affairs of the Company and its
Subsidiaries in connection with the making of the Loans and the issuance of
Letters of Credit hereunder and that it has made and shall continue to make its
own appraisal of the creditworthiness of the Company and its Subsidiaries. No
Agent shall have any duty or responsibility, either initially or on a continuing
basis, to make any such investigation or any such appraisal on behalf of the
Lenders or, except as expressly provided elsewhere in this Agreement to provide
any Lender with any credit or other information with respect thereto, whether
coming into its possession before the making of the Loans or at any time or
times thereafter, and no Agent shall have any responsibility with respect to the
accuracy of or the completeness of any information provided to the lenders.

9.4 Right to Indemnity.

      Each Lender, in proportion to its Pro Rata Share, severally agrees to
indemnify each Agent, to the extent that such Agent shall not have been
reimbursed by the Company, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses
(including, without limitation, reasonable counsel fees and disbursements) or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against such Agent in performing its duties hereunder or under
the other Loan Documents or otherwise in its capacity as such Agent in any way
relating to or arising out of this Agreement or the other Loan Documents;
provided that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Agent's gross negligence or
willful misconduct. If any indemnity furnished to any Agent for any purpose
shall, in the opinion of such Agent, be insufficient or become impaired, such
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished.

9.5 Successor Administrative Agent and Swing Line Lender.

      A. Successor Administrative Agent. The Administrative Agent may resign at
any time by giving thirty (30) days' prior written notice thereof to the Lenders
and the Company and shall so resign upon the written request of the Company,
provided, that the Company shall have the right to request such resignation of
the Administrative Agent only so long as (i) CSFB is then the Administrative
Agent and the 


                                      127

<PAGE>

Commitments of CSFB as Lender shall equal an amount less than 5% of the
aggregate Commitment of all Lenders, (ii) no Default or Event of Default shall
have occurred and be continuing, and (iii) Alchemy shall have directed the
Company to make such request and Alchemy shall own or control at least 51% of
the combined voting power of the voting Securities of each the Company, each
Holding Company, ESP and ENR. Upon any such notice of resignation, the Requisite
Lenders shall have the right, upon five (5) Business Days' notice to the
Company, to appoint a successor Administrative Agent. Upon the acceptance of any
appointment as the Administrative Agent hereunder by a successor Administrative
Agent, that successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring the
Administrative Agent and the retiring the Administrative Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring the Administrative Agent's resignation hereunder as the Administrative
Agent, the provisions of this Section 9 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was the Administrative Agent
under this Agreement.

      B. Successor Swing Line Lender. Any resignation of the Administrative
Agent pursuant to subsection 9.5A shall also constitute the resignation of CSFB
or its successor as the Swing Line Lender, and any successor Administrative
Agent appointed pursuant to subsection 9.5A shall, upon its acceptance of such
appointment, become the successor Swing Line Lender for all purposes hereunder.
In such event (i) the Company shall prepay any outstanding Swing Line Loans made
by the retiring Administrative Agent in its capacity as Swing Line Lender, (ii)
upon such prepayment, the retiring Administrative Agent and Swing Line Lender
shall surrender the Swing Line Note held by it to the Company for cancellation,
and (iii) the Company shall issue a new Swing Line Note to the successor
Administrative Agent and Swing Line Lender substantially in the form of Exhibit
V-B annexed hereto, in the principal amount of the Swing Line Loan Commitment
then in effect and with other appropriate insertions.

9.6 Collateral Documents; Successor Collateral Agent.

      Each Lender hereby further authorizes the Collateral Agent to enter into
each Collateral Document as secured party on behalf of and for the benefit of
the Lenders and the other beneficiaries named therein and agrees to be bound by
the terms of each Collateral Document; provided that the Collateral Agent shall
not enter into or consent to any amendment, modification, termination or waiver
of any provision contained in any Collateral Document without the prior consent
of the Requisite Lenders (or, if required pursuant to subsection 10.6, all the
Lenders); provided further, however, that, without further written consent or
authorization from any Lender, the Collateral Agent may execute any documents or
instruments necessary to effect the release of any asset constituting Collateral
from the Lien of the applicable Collateral Document in the event that such asset
is sold or otherwise disposed of in a transaction effected in accordance with
subsection 7.7(iv), 7.7(v), 7.7(vi) or 7.7(vii) or to the extent otherwise
required by any Collateral Document. Anything contained in any of the Loan
Documents to the contrary notwithstanding, each Lender agrees that no Lender
shall have any right individually to realize upon any of the Collateral under
any Collateral Document (including without limitation through the exercise of a
right of set-off against call deposits of such Lender in which any funds on
deposit in the Collateral Account may from time to time be invested), it being
understood and agreed that all rights and remedies under the Collateral
Documents may be exercised solely by the Collateral Agent for the benefit of the
Lenders and the other beneficiaries named therein in accordance with the terms
thereof. The Collateral Agent may resign at any time, and a successor Collateral
Agent may be appointed, in accordance with subsection 9.5 as if such subsection
9.5 applied to the Collateral Agent in lieu of the Administrative Agent.

                                   SECTION 10.
                                  MISCELLANEOUS

10.1 Assignments and Participations in Loans, Letters of Credit.

      A. General. Subject to subsection 10.1B or 10.1C, as applicable, each
Lender shall have the right at any time to (i) sell, assign, transfer or
negotiate to any Eligible Assignee, or (ii) sell participations to any Person
in, all or any part of its Commitments (together with its Letters of Credit or
participations therein made or arising pursuant to its Revolving Loan
Commitment) or any Loan or Loans made by it or any other interest herein or in
any other Obligations owed to it; provided that no such sale, assignment,
transfer or participation shall, without the consent of the Company, require the
Company to file a registration statement with the Securities and Exchange
Commission or apply to qualify such sale, assignment, transfer or participation
under the securities laws of any state; provided further that no such sale,
assignment or transfer described in clause (i) above shall be effective unless
and until an Assignment Agreement effecting such sale, assignment or transfer
shall have been accepted by the Administrative Agent and recorded in the
Register as provided in subsection 10.1B(ii); provided, further that no such
sale, assignment, transfer or participation of any Letter of Credit or any
participation therein may be made separately from a sale, assignment, transfer
or participation of a corresponding interest in the Revolving Loan Commitment
and the Revolving Loans of the Lender effecting such sale, assignment, transfer
or participation. Except as otherwise provided in this subsection 10.1, no
Lender shall, as between the Company and such Lender, be relieved of any of its
obligations hereunder as a result of any sale, assignment, transfer or
negotiation of, or any granting of participations in, all or any part of its
Commitments or the Loans, the Letters of Credit or participations therein or the
other Obligations owed to such Lender.

      B. Assignments.

            (i) Amounts and Terms of Assignments. Each Commitment, Loan, Letter
      of Credit, or participation therein or other Obligation may (a) be
      assigned in any amount to another Lender who is a Non-Defaulting Lender,
      or to an Approved Fund or an Affiliate of the assigning Lender or another
      Lender who, in either such case, is a Non-Defaulting Lender, with the
      giving of notice to the Company and the Administrative Agent or (b) be
      assigned in an aggregate amount of not less than $5,000,000 (or such
      lesser amount as shall constitute the aggregate amount of the Commitments,
      Loans, Letters of Credit, and participations therein and other Obligations
      of the assigning Lender) to any other Eligible Assignee with the consent
      of the Administrative Agent (such consent not to be unreasonably withheld)
      and, so long as no Default or Event of Default shall have occurred and be
      continuing, following consultation with the Company. To the extent of any
      such assignment in accordance with either clause (a) or (b) above, the
      assigning Lender shall be relieved of its obligations with respect to its
      Commitments, Loans, Letters of Credit, or participations therein or other
      Obligations or the portion thereof so assigned. The parties to each such
      assignment shall execute and deliver to the Administrative Agent, for its
      acceptance and recording in the Register, an Assignment Agreement,
      together with a processing fee of $3,500 payable by the assigning Lender,
      such certificates, documents or other evidence, if any, with respect to
      United States federal income tax withholding matters as the assignee under
      such Assignment Agreement may be required to deliver to the Administrative
      Agent pursuant to subsection 2.7B(iii)(a) and, if requested by the
      Administrative Agent, a completed administrative questionnaire in the
      Administrative Agent's customary form with respect to the assignee under
      such Assignment Agreement. Upon such execution, delivery, acceptance and
      recordation, from 


                                      129

<PAGE>

      and after the effective date specified in such Assignment Agreement, (y)
      the assignee thereunder shall be a party hereto and, to the extent that
      rights and obligations hereunder have been assigned to it pursuant to such
      Assignment Agreement, shall have the rights and obligations of a Lender
      hereunder and (z) the assigning Lender thereunder shall, to the extent
      that rights and obligations hereunder have been assigned by it pursuant to
      such Assignment Agreement, relinquish its rights and be released from its
      obligations under this Agreement (and, in the case of an Assignment
      Agreement covering all or the remaining portion of an assigning Lender's
      rights and obligations under this Agreement, such Lender shall cease to be
      a party hereto); provided that, anything contained in any of the Loan
      Documents to the contrary notwithstanding, if such Lender is the Issuing
      Bank such Lender shall continue to have all rights and obligations of the
      Issuing Bank with respect to outstanding Letters of Credit until the
      cancellation or expiration of such Letters of Credit and the reimbursement
      of any amounts drawn thereunder. The Commitments hereunder shall be
      modified to reflect the Commitments of such assignee and any remaining
      Commitments of such assigning Lender and, if any such assignment occurs
      after the issuance of the Notes hereunder, the assigning Lender shall
      surrender its applicable Notes and, upon such surrender, new Notes shall
      be issued to the assignee and, if applicable, to the assigning Lender,
      substantially in the form of Exhibit IV-A or B or Exhibit V-A annexed
      hereto, as the case may be, with appropriate insertions, to reflect the
      new Commitments and/or outstanding Term Loans of the assignee and the
      assigning Lender.

            (ii) Acceptance by the Administrative Agent; Recordation in
      Register. Upon its receipt of an Assignment Agreement executed by an
      assigning Lender and an assignee representing that it is an Eligible
      Assignee, together with the processing fee referred to in subsection
      10.1B(i) and any certificates, documents or other evidence with respect to
      United States federal income tax withholding matters that such assignee
      may be required to deliver to the Administrative Agent pursuant to
      subsection 2.7B(iii), the Administrative Agent shall, if such Assignment
      Agreement has been completed and is in substantially the form of Exhibit
      XII hereto and if the Administrative Agent has consented to the assignment
      evidenced thereby (to the extent such consent is required pursuant to
      subsection 10.1B(i)), (a) accept such Assignment Agreement by executing a
      counterpart thereof as provided therein (which acceptance shall evidence
      any required consent of the Administrative Agent to such assignment), (b)
      record the information contained therein in the Register, and (c) give
      prompt notice thereof to the Company. The Administrative Agent shall
      maintain a copy of each Assignment Agreement delivered to and accepted by
      it as provided in this subsection 10.1B(ii).

      C. Participations. The holder of any participation, other than an
Affiliate of the Lender granting such participation, shall not be entitled to
require such Lender to take or omit to take any action hereunder except action
(i) effecting the extension of the final maturity of the Loan allocated to such
participation, (ii) effecting a reduction of the principal amount of or
affecting the rate of interest payable on any Loan or any fee allocated to such
participation, (iii) releasing all or substantially all of the Collateral, or
(iv) releasing all or substantially all of the Guarantors from their obligations
under the Guaranties, and all amounts payable by the Company hereunder. The
Company and each Lender hereby acknowledge and agree that, solely for purposes
of subsections 2.6D, 2.7, 3.6, 10.2, 10.3, 10.4 and 10.5, (a) any participation
will give rise to a direct obligation of the Company to the participant and (b)
the participant shall be considered to be a "Lender"; provided that the
aggregate amount payable to a Lender and its participants pursuant to
subsections 2.6D, 2.7, 3.6, 10.2 and 10.3 shall not exceed the amount that would
have been payable to such Lender as if such Lender had not sold such
participation.


                                      130

<PAGE>

      D. Assignments to Federal Reserve Banks. In addition to the assignments
and participations permitted under the foregoing provisions of this subsection
10.1, any Lender may assign and pledge all or any portion of its Loans, the
other Obligations owed to such Lender and its Notes to any Federal Reserve Bank
as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any operating circular issued by such Federal Reserve
Bank; provided that (i) no Lender shall, as between the Company and such Lender,
be relieved of any of its obligations hereunder as a result of any such
assignment and pledge and (ii) in no event shall such Federal Reserve Bank be
considered to be a "Lender" or be entitled to require the assigning Lender to
take or omit to take any action hereunder.

      E. Information. Each Lender may furnish any information concerning the
Company and its Subsidiaries in the possession of that Lender from time to time
to assignees and participants (including prospective assignees and
participants), subject to subsection 10.20.

      F. Limitation. No assignee, participant or other transferee or any
Lender's rights shall be entitled to receive any greater payment under
subsection 2.7 than such Lender would have been entitled to receive with respect
to the rights transferred, unless such transfer is made with the Company's prior
written consent or at a time when the circumstances giving rise to such greater
payment did not exist.

10.2 Expenses.

      Whether or not the transactions contemplated hereby shall be consummated,
the Company agrees to pay promptly (i) all the actual and reasonable costs and
out of pocket expenses of the Agents in connection with the preparation of the
Loan Documents; (ii) all the actual and reasonable costs of furnishing all
opinions by counsel for the Company (including without limitation any opinions
requested by the Lenders or Agents as to any legal matters arising hereunder)
and of the Company's performance of and compliance with all agreements and
conditions on its part to be performed or complied with under this Agreement and
the other Loan Documents including, without limitation, with respect to
confirming compliance with environmental and insurance requirements; (iii) the
reasonable fees, expenses and disbursements of counsel to the Agents (including
allocated costs of internal counsel) in connection with the negotiation,
preparation, execution and administration of the Loan Documents and the Loans
and any consents, amendments, waivers or other modifications hereto or thereto
and any other documents or matters requested by the Company; (iv) all other
actual and reasonable costs and expenses incurred by the Agents in connection
with the negotiation, preparation and execution of the Loan Documents and the
transactions contemplated hereby and thereby; and (v) after the occurrence of a
Default or Event of Default, all the respective costs and expenses, including
reasonable attorneys' fees (including allocated costs of internal counsel) and
costs of settlement, incurred by the Agents and the Lenders in enforcing any
Obligations of or in collecting any payments due from the Company hereunder or
under the other Loan Documents by reason of such Default or Event of Default or
in connection with any refinancing or restructuring of the credit arrangements
provided under this Agreement in the nature of a "work-out" or pursuant to any
insolvency or bankruptcy proceedings.

10.3 Indemnity.

      In addition to the payment of expenses pursuant to subsection 10.2,
whether or not the transactions contemplated hereby shall be consummated, the
Company agrees to defend, indemnify, pay and hold harmless the Agents and the
Lenders, and the officers, directors, employees, agents, attorneys and
affiliates of the Agents and the Lenders (collectively called the "Indemnitees")
from and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, 


                                      131

limitation the reasonable fees and disbursements of counsel for such
Indemnitees, and all such fees and disbursements, as well as other costs and
expenses, incurred by Indemnitees in connection with any investigative,
administrative or judicial proceeding commenced or threatened by any Person,
whether or not any such Indemnitee shall be designated as a party or a potential
party thereto), whether direct, indirect or consequential and whether based on
any federal, state or foreign laws, statutes, rules or regulations (including
without limitation securities and commercial laws, statutes, rules or
regulations and Environmental Laws), on common law or equitable cause or on
contract or otherwise, that may be imposed on, incurred by, or asserted against
any such Indemnitee, in any manner relating to or arising out of this Agreement
or the other Loan Documents or the transactions contemplated hereby or thereby
(including without limitation the Lenders' agreement to make the Loans hereunder
or the use or intended use of the proceeds of any of the Loans or the issuance
of Letters of Credit hereunder or the use or intended use of any of the Letters
of Credit) or any Environmental Liabilities that arise from or relate to the
management, use, control, ownership, occupancy or operation of any Facility or
assets of any Loan Party or its subsidiaries (including without limitation, all
on-site and off-site activities involving Hazardous Materials), or the Release
or threatened Release of any Hazardous Materials (or allegations of the same) on
or from any of the Facilities or on or from any other property where Hazardous
Materials are or were (or are or were alleged to be) Released or threatened to
be Released in connection with any of the Facilities or the business of any of
the Loan Parties, their subsidiaries, or any predecessor in interest to the Loan
Parties or their subsidiaries (collectively called the "Indemnified
Liabilities"); provided that the Company shall not have any obligation to any
Indemnitee hereunder with respect to any Indemnified Liabilities to the extent,
and only to the extent, of any particular liability, obligation, loss, damage,
penalty, claim, cost, expense or disbursement that arose from the gross
negligence or willful misconduct of that Indemnitee as determined by a final
judgment of a court of competent jurisdiction. To the extent that the
undertaking to defend, indemnify, pay and hold harmless set forth in the
preceding sentence may be unenforceable because it is violative of any law or
public policy, the Company shall contribute the maximum portion that it is
permitted to pay and satisfy under applicable law to the payment and
satisfaction of all Indemnified Liabilities incurred by the Indemnitees or any
of them.

10.4 Set-Off; Security Interest in Deposit Accounts.

      In addition to any rights now or hereafter granted under applicable law
and not by way of limitation of any such rights, upon the occurrence and during
the continuance of any Event of Default, each Lender is hereby authorized by the
Company at any time or from time to time, without notice to the Company or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and to apply any and all deposits (general or special, including,
but not limited to, Indebtedness evidenced by certificates of deposit, whether
matured or unmatured, but not including trust accounts) and any other
Indebtedness at any time held or owing by that Lender (at any office of that
Lender wherever located) to or for the credit or the account of the Company
against and on account of the obligations and liabilities of the Company to that
Lender under this Agreement, the Notes, the Letters of Credit and participations
therein, including, but not limited to, all claims of any nature or description
arising out of or connected with this Agreement, the Notes, the Letters of
Credit and participations therein or any other Loan Document, irrespective of
whether or not (i) that Lender shall have made any demand hereunder or (ii) the
principal of or the interest on the Loans or any amounts in respect of the
Letters of Credit or any other amounts due hereunder shall have become due and
payable pursuant to Section 8 and although said obligations and liabilities, or
any of them, may be contingent or unmatured. The Company hereby further grants
to the Administrative Agent and each Lender a security interest in all deposits
and accounts maintained with the Administrative Agent or such Lender as security
for the Obligations.

10.5 Ratable Sharing.

      The Lenders hereby agree among themselves that if any of them shall,
whether by voluntary payment (other than a voluntary prepayment of Loans made
and applied in accordance with the terms of this Agreement), by realization upon
security, through the exercise of any right of set-off or banker's lien, by
counterclaim or cross action or by the enforcement of any right under the Loan
Documents or otherwise, or as adequate protection of a deposit treated as cash
collateral under the Bankruptcy Code, receive payment or reduction of a
proportion of the aggregate amount of principal, interest, amounts payable in
respect of Letters of Credit, fees and other amounts then due and owing to that
Lender hereunder or under the other Loan Documents (collectively, the "Aggregate
Amounts Due" to such Lender) which is greater than the proportion received by
any other Lender in respect of the Aggregate Amounts Due to such other Lender,
then the Lender receiving such proportionately greater payment shall (i) notify
the Administrative Agent and each other Lender of the receipt of such payment
and (ii) apply a portion of such payment to purchase participations (which it
shall be deemed to have purchased from each seller of a participation
simultaneously upon the receipt by such seller of its portion of such payment)
in the Aggregate Amounts Due to the other Lenders so that all such recoveries of
Aggregate Amounts Due shall be shared by all the Lenders in proportion to the
Aggregate Amounts Due to them; provided that if all or part of such
proportionately greater payment received by such purchasing the Lender is
thereafter recovered from such Lender upon the bankruptcy, reorganization or
insolvency proceeding of the Company or otherwise, those purchases shall be
rescinded and the purchase prices paid for such participations shall be returned
to such purchasing Lender ratably to the extent of such recovery, but without
interest. The Company expressly consents to the foregoing arrangement and agrees
that any holder of a participation so purchased may exercise any and all rights
of banker's lien, set-off or counterclaim with respect to any and all monies
owing by the Company to that holder with respect thereto as fully as if that
holder were owed the amount of the participation held by that holder.

10.6 Amendments and Waivers.

      A. No amendment, modification, termination or waiver of any provision of
this Agreement or of the Notes, or consent to any departure by the Company or
any other Loan Party therefrom, shall in any event be effective without the
written concurrence of the Requisite Lenders; provided that any such amendment,
modification, termination, waiver or consent which: (a) reduces the principal
amount of any of the Loans; (b) reduces the percentage specified in the
definition of the "Requisite Lenders" (it being understood that, with the
consent of the Requisite Lenders, additional extensions of credit pursuant to

B Loans, Term B Loan Commitments, Revolving Loans and Revolving Loan Commitments
are included on the Closing Date); (c) changes in any manner any provision of
this Agreement which, by its terms, expressly requires the approval or

date on which any interest or any fees are payable; (g) decreases the interest
rate borne by any of the Loans (other than any waiver of any increase in the

amount of any fees payable hereunder; (h) increases the maximum duration of
Interest Periods permitted hereunder; (i) releases all or substantially all of
the Collateral; (j) except as required by any Guaranty, releases any of the
Guarantors from their obligations under the Guaranties; (k) reduces the amount
or postpones the due date of any amount payable in respect of, or extends the
required expiration

<PAGE>

date of, any Letter of Credit; (l) changes the obligations of the Lenders
relating to the purchase of participations in Letters of Credit in any manner
that could be adverse to any Issuing Bank; or (m) changes in any manner the
provisions contained in subsection 8.1 or this subsection 10.6; shall be
effective only if evidenced by a writing signed by or on behalf of all the
Lenders to whom Obligations are owed or who have Commitments outstanding being
directly affected by such amendment, modification, termination, waiver or
consent; provided further that no such amendment, modification, termination or
waiver of any such provision of any Collateral Document having the effect of
securing thereunder additional Indebtedness (other than Indebtedness comprising
Obligations and Hedge Agreements) by the Collateral shall be effective without
the written concurrence of Lenders having or holding more than 66-2/3% of the
sum of the aggregate Tranche A Term Loan Exposure of all Lenders plus the
aggregate Tranche B Term Loan Exposure of all Lenders plus the aggregate
Revolving Loan Exposure of all Lenders. In addition, (i) any amendment,
modification, termination or waiver of any of the provisions contained in
Section 4 shall be effective only if evidenced by a writing signed by or on
behalf of the Administrative Agent and the Requisite Lenders, (ii) no amendment,
modification, termination or waiver of any provision of any Note shall be
effective without the written concurrence of the Lender which is the holder of
that Note, (iii) no increase in the Commitments of any Lender over the amount
thereof then in effect shall be effective without the written concurrence of
that Lender, it being understood and agreed that in no event shall waivers or
modifications of conditions precedent, covenants, Defaults, Events of Default or
of a mandatory prepayment or a reduction of any or all of the Commitments be
deemed to constitute an increase of the Commitment of any Lender and that an
increase in the available portion of any Commitment of any Lender shall not be
deemed to constitute an increase in the Commitment of such Lender, (iv) no
amendment, modification, termination or waiver of any provision of subsection
2.1A(iv) or any other provision of this Agreement relating to the Swing Line
Loan Commitment or the Swing Line Loans shall be effective without the written
concurrence of the Swing Line Lender, (v) no amendment, modification,
termination or waiver of any provision of Section 3 relating to the rights or
obligations of the Issuing Bank shall be effective without the written
concurrence of the Issuing Bank with respect to any Letter of Credit then
outstanding, and (vi) no amendment, modification, termination or waiver of any
provision of Section 9 or of any other provision of this Agreement which, by its
terms, expressly requires the approval or concurrence of the Administrative
Agent shall be effective without the written concurrence of the Administrative
Agent. The Administrative Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or
consents on behalf of that Lender and no amendment, modification, termination or
waiver of any provision of subsection 2.4 which has the effect of changing any
voluntary or mandatory prepayments or Commitment reductions applicable to any
Class (the "Affected Class") in a manner that disproportionately disadvantages
such Class relative to the other Class shall be effective without the written
concurrence of the Requisite Class Lenders of the Affected Class (it being
understood and agreed that any amendment, modification, termination or waiver of
any such provision which only postpones or reduces any voluntary or mandatory
prepayment or Commitment reduction from those set forth in subsection 2.4 with
respect to one Class but not the other Classes shall be deemed to
disproportionately disadvantage such one Class but not to disproportionately
disadvantage such other Classes for purposes of this clause). Any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on the Company in any
case shall entitle the Company to any other or further notice or demand in
similar or other circumstances. Any amendment, modification, termination, waiver
or consent effected in accordance with this subsection 10.6 shall be binding
upon each Lender at the time outstanding, each future Lender and, if signed by
the Company, on the Company. Prior to or simultaneously with any request for any
amendment, waiver or other modification of subsection 7.6D that arises out of
the Company's or any of its Subsidiaries' making a bid for, or entering into, a
State Contract, the Company shall deliver to each Lender a reasonably detailed
summary of the material terms of such bid or contract.

      B. If, in connection with any proposed change, waiver, discharge or
termination to any of the provision of this Agreement as contemplated by the
proviso in the first sentence of this subsection 10.6, the consent of the
Requisite Lenders is obtained but consent of one or more of such other Lenders
whose consent is required is not obtained, then, so long as no Default shall
have occurred and be continuing, the Company may, so long as all non-consenting
Lenders are so treated, elect to terminate such Lender as a party to this
Agreement; provided that, concurrently with such termination, (i) the Company
shall pay that Lender all principal, interest and fees and other amounts due to
be paid to such Lender with respect to all periods through such date of
termination, (ii) another bank, financial institution or other entity
satisfactory to the Company and the Administrative Agent (or if the
Administrative Agent is also a Lender to be terminated, the successor
Administrative Agent) shall agree, as of such date, to become a Lender for all
purposes under this Agreement (whether by assignment or amendment) and to assume
all obligations of the Lender to be terminated as of such date, and (iii) all
documents and supporting materials necessary, in the judgment of the
Administrative Agent (or if the Administrative Agent is also a Lender to be
terminated, the successor Administrative Agent) to evidence the substitution of
such Lender shall have been received and approved by the Administrative Agent as
of such date.

10.7 Independence of Covenants.

      All covenants hereunder shall be given independent effect so that if a
particular action or condition is not permitted by any of such covenants, the
fact that it would be permitted by an exception to, or would otherwise be within
the limitations of, another such covenant shall not avoid the occurrence of an
Default or Event of Default if such action is taken or condition exists.

10.8 Notices.

      Unless otherwise specifically provided herein, any notice or other
communication herein required or permitted to be given shall be in writing and
may be personally served, telecopied, telexed or sent by United States mail or
courier service and shall be deemed to have been given when delivered in person
or by courier service, upon receipt of telecopy or telex, or four Business Days
after depositing it in the United States mail, registered or certified, with
postage prepaid and properly addressed; provided that notices to the
Administrative Agent shall not be effective until received. For the purposes
hereof, the address of each party hereto shall be as set forth on Schedule 10.8
attached hereto, or such other address as shall be designated by such party in a
written notice delivered to the Administrative Agent and the Company.

10.9 Survival of Representations, Warranties and Agreements.

      A. All representations, warranties and agreements made herein shall
survive the execution and delivery of this Agreement and the making of the Loans
and the issuance of the Letters of Credit hereunder.

      B. Notwithstanding anything in this Agreement or implied by law to the
contrary, the agreements of the Company set forth in subsections 2.6D, 2.7,
3.5A, 3.6, 10.2, 10.3 and 10.4 and the agreements of the Lenders set forth in
subsections 9.2C, 9.4, 10.4, 10.5 and 10.20 shall survive the payment of the
Loans, the cancellation or expiration of the Letters of Credit and the
reimbursement of any amounts drawn or paid thereunder, and the termination of
this Agreement.


                                      135

<PAGE>

10.10 Failure or Indulgence Not Waiver; Remedies Cumulative.

      No failure or delay on the part of any Agent or any Lender in the exercise
of any power, right or privilege hereunder or under any other Loan Document
shall impair such power, right or privilege or be construed to be a waiver of
any default or acquiescence therein, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or
of any other power, right or privilege. All rights and remedies existing under
this Agreement and the other Loan Documents are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

10.11 Marshalling; Payments Set Aside.

      Neither any Agent nor any Lender shall be under any obligation to marshal
any assets in favor of the Company or any other party or against or in payment
of any or all of the Obligations. To the extent that the Company makes a payment
or payments to the Administrative Agent or the Lenders (or to the Administrative
Agent or Collateral Agent for the benefit of the Lenders), or any Agent or the
Lenders enforce any security interests or exercise their rights of setoff, and
such payment or payments or the proceeds of such enforcement or setoff or any
part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside and/or required to be repaid to a trustee, receiver or
any other party under any bankruptcy law, any other state or federal law, common
law or any equitable cause, then, to the extent of such recovery, the obligation
or part thereof originally intended to be satisfied, and all Liens, rights and
remedies therefor or Related thereto, shall be revived and continued in full
force and effect as if such payment or payments had not been made or such
enforcement or setoff had not occurred.

10.12 Severability.

      In case any provision in or obligation under this Agreement or the Notes
shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining provisions or obligations, or of
such provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

10.13 Obligations Several; Independent Nature of the Lenders' Rights.

      The obligations of the Lenders hereunder are several and no Lender shall
be responsible for the obligations or Commitments of any other Lender hereunder.
Nothing contained herein or in any other Loan Document, and no action taken by
the Lenders pursuant hereto or thereto, shall be deemed to constitute the
Lenders as a partnership, an association, a joint venture or any other kind of
entity. The amounts payable at any time hereunder to each Lender shall be a
separate and independent debt, and each Lender shall be entitled to protect and
enforce its rights arising out of this Agreement and it shall not be necessary
for any other Lender to be joined as an additional party in any proceeding for
such purpose.

10.14 Maximum Amount.

      A. It is the intention of the Company and the Lenders to conform strictly
to the usury and similar laws relating to interest from time to time in force,
and all agreements between the Loan Parties and their respective Subsidiaries
and the Lenders, whether now existing or hereafter arising and whether oral or
written, are hereby expressly limited so that in no contingency or event
whatsoever, whether by acceleration of maturity hereof or otherwise, shall the
amount paid or agreed to be paid in the aggregate to the Lenders as interest
(whether or not designated as interest, and including any amount otherwise


                                      136

<PAGE>

designated but deemed to constitute interest by a court of competent
jurisdiction) hereunder or under the other Loan Documents or in any other
agreement given to secure the Indebtedness or obligations of the Company to the
Lenders, or in any other document evidencing, securing or pertaining to the
Indebtedness evidenced hereby, exceed the maximum amount permissible under
applicable usury or such other laws (the "Maximum Amount"). If under any
circumstances whatsoever fulfillment of any provision hereof, or any of the
other Loan Documents, at the time performance of such provision shall be due,
shall involve exceeding the Maximum Amount, then, ipso facto, the obligation to
be fulfilled shall be reduced to the Maximum Amount. For the purposes of
calculating the actual amount of interest paid and/or payable hereunder in
respect of laws pertaining to usury or such other laws, all sums paid or agreed
to be paid to the holder hereof for the use, forbearance or detention of the
Indebtedness of the Company evidenced hereby, outstanding from time to time
shall, to the extent permitted by Applicable Law, be amortized, pro-rated,
allocated and spread from the date of disbursement of the proceeds of the Notes
until payment in full of all of such Indebtedness, so that the actual rate of
interest on account of such Indebtedness is uniform through the term hereof. The
terms and provisions of this subsection shall control and supersede every other
provision of all agreements between the Company or any endorser of the Notes and
the Lenders.

      B. If under any circumstances any Lender shall ever receive an amount
which would exceed the Maximum Amount, such amount shall be deemed a payment in
reduction of the principal amount of the Loans and shall be treated as a
voluntary prepayment under subsection 2.4B(i) and shall be so applied in
accordance with subsection 2.4 hereof or if such excessive interest exceeds the
unpaid balance of the Loans and any other Indebtedness of the Company in favor
of such Lender, the excess shall be deemed to have been a payment made by
mistake and shall be refunded to the Company.

10.15 Headings.

      Section and subsection headings in this Agreement are included herein for
convenience of reference only and shall not constitute a part of this Agreement
for any other purpose or be given any substantive effect.

10.16 Applicable Law.

      THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

10.17 Successors and Assigns.

      This Agreement shall be binding upon the parties hereto and their
respective successors and assigns and shall inure to the benefit of the parties
hereto and the successors and assigns of the Lenders (it being understood that
the Lenders' rights of assignment are subject to subsection 10.1). Neither the
Company's nor the Parent's rights or obligations hereunder nor any interest
therein may not be assigned or delegated by the Company or the Parent without
the prior written consent of all Lenders.

10.18 Consent to Jurisdiction and Service of Process.

      ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST THE COMPANY OR THE PARENT ARISING
OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY
OBLIGATIONS THEREUNDER, MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF
