                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1994
 
NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     ORGANIZATION AND BASIS OF PRESENTATION  The accompanying consolidated
financial statements include the accounts of NSC Corporation (the "Company") and
its wholly-owned subsidiaries, National Surface Cleaning, Inc. ("NSC") and
National Service Cleaning Corp. ("NSCC"), NSC Industrial Services Corp.
("Industrial") through May 4, 1993 (date of disposition); and since February 5,
1992 (date of acquisition) through May 4, 1993 (date of disposition), Combined
Plant Services Corp. and its affiliate, Gundersen/Viking (collectively, "CPS");
and since April 17, 1992 (date of acquisition) through May 4, 1993 (date of
disposition) Miami Valley Pressure Cleaning, Inc. and its affiliate, M.V.
Industrial Services Inc. (collectively, "MVIS"). All intercompany transactions
have been eliminated in consolidation. The Company is a Delaware corporation and
was a seventy percent-owned subsidiary of OHM Corporation ("OHM") through May 3,
1993. On May 4, 1993, pursuant to a Purchase Agreement among the Company,
Industrial, OHM, The Brand Companies, Inc. ("Brand") and Waste Management, Inc.
("WMI"), now known as WMX Technologies, Inc., the Company acquired the asbestos
abatement division of Brand (the "Division") in exchange for 4,010,000 shares of
the Company's common stock and all the common stock of Industrial. As of
December 31, 1993 and 1994, OHM and Rust International Inc. (a successor company
to Brand and hereinafter referred to as "Rust") each owned approximately forty
percent of the Company's common stock.
 
     REVENUE AND COST RECOGNITION  The Company primarily derives its revenues
from providing asbestos abatement and related services under fixed price, time
and materials and unit price contracts. The Company recognizes revenues and
related income from its fixed and unit price contracts in process using the
percentage-of-completion method of accounting. Revenues from time and
material-type contracts are recorded based on cost incurred. Provisions for
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Revenues are recognized for amounts under pending claims
when management believes it is probable the claim will result in additional
contract revenues and the amount can be reliably estimated. Contract costs
include all direct labor, material, per diem, subcontract and other direct and
indirect costs related to the contract performance. Selling, general and
administrative expenses are charged to expense as incurred. The asset, "costs
and estimated earnings on contracts in process in excess of billings,"
represents revenues recognized in excess of amounts billed. The liability,
"billings on contracts in process in excess of costs and estimated earnings,"
represents billings in excess of revenues recognized.
 
     DIRECT SUBCONTRACT COSTS  The Company incurs a substantial amount of direct
subcontract costs which are passed through to its clients. These costs result
from the use of subcontractors on projects for labor, transportation and
disposal of asbestos materials, analytical and restoration services, and other
removal-related services. The Company believes that net revenues, excluding
direct subcontract costs, more accurately reflect the amounts earned for
activities performed by the Company. Accordingly, the Company reports direct
subcontract costs as a reduction of gross revenues to arrive at net revenues.
 
     INVENTORIES  Inventories primarily are comprised of operating supplies and
are stated at the lower of cost or market. Cost is determined using the
first-in, first-out (FIFO) method.
 
     PROPERTY AND EQUIPMENT  Property and equipment are stated at cost.
Depreciation is provided over the estimated useful lives of the respective
assets using the straight-line method.
 
     GOODWILL  Goodwill is amortized over a 40-year life and is reviewed on an
ongoing basis by the Company's management based on several factors including,
among others, the Company's projection of future operations and their related
impact on cash flows. If an impairment of the carrying value were to be
indicated by this review, the Company would adjust the carrying value of
goodwill to its estimated fair value.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     INCOME TAXES  Effective January 1, 1992, the Company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No.
109"), which changed its method of accounting for income taxes from the deferred
method to the liability method. The cumulative effect of the adoption of SFAS
No. 109 resulted in the recognition of a deferred tax liability of $1,000,000.
Under the liability method, deferred tax assets and liabilities are determined
based on differences between the financial reporting and tax bases of assets and
liabilities using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
     ALLOCATION OF CORPORATE EXPENSES  Prior to May 4, 1993, the Company
received certain administrative and other services from OHM and its other
subsidiaries, which included financial, legal, certain senior executive
management, insurance, employee benefits, and other services. For such services,
the Company was charged a proportional share of the total costs. The Company
believes that such transactions with OHM and its affiliates were made on terms
no less favorable than could have been obtained in arms-length transactions with
independent third parties. A summary of significant transactions with affiliates
of the Company is presented in Note 10.
 
     CASH EQUIVALENTS AND CASH FLOW INFORMATION  The Company considers all
investments having a maturity of three months or less when purchased to be cash
equivalents. Cash equivalents are stated at cost which approximates fair market
value. Cash paid for income taxes was $263,000, $1,063,000, and $1,597,000 for
1994, 1993, and 1992, respectively. Cash paid for interest was $802,000,
$945,000, and $1,886,000 for 1994, 1993, and 1992, respectively.
 
     NET INCOME PER SHARE  The net income (loss) per share amounts for 1994,
1993, and 1992, have been computed by dividing net income (loss) by the
weighted-average number of common and common equivalent shares, if dilutive,
outstanding during the respective periods.
 
     RECLASSIFICATIONS  Certain reclassifications have been made to prior year
financial statements to conform with the current year presentation.
 
NOTE 2 -- ACQUISITION OF THE DIVISION
 
     On December 23, 1992, the Company entered into a Purchase Agreement among
the Company, Industrial, OHM, Brand and WMI, pursuant to which the Company
purchased, on May 4, 1993, the Division in exchange for 4,010,000 shares of the
Company's common stock and the capital stock of Industrial. The acquisition of
the Division has been accounted for using the purchase method and, accordingly,
the acquired assets and assumed liabilities have been recorded at their
estimated fair values as of May 4, 1993. The accompanying consolidated financial
statements include the results of operations for the Division since May 4, 1993.
Pursuant to the Purchase Agreement, Brand guaranteed to the Company that, except
for certain contracts, the contracts assumed by the Company from Brand to
provide asbestos abatement and other related services would yield certain
minimum gross margins depending on the type of contract. Gross margin is defined
as revenues derived from these contracts less certain specified costs of
performing such contracts divided by such revenues. Brand paid the Company
$3,775,000 pursuant to this provision of the Purchase Agreement for the year
ended December 31, 1993. In addition, pursuant to the Purchase Agreement, Brand
guaranteed the collection of the full amount of all the Division's billed and
unbilled accounts receivables which were acquired by the Company. Pursuant to
this provision of the Purchase Agreement, Brand paid the Company $7,620,000
during the year ended December 31, 1993. As a condition of the Purchase
Agreement, on May 4, 1993, the Company entered into a $50,000,000 revolving
credit facility (see Note 7 - Long-Term Debt), repaid all of its indebtedness to
OHM, and terminated the Cash Management Agreement and Management Services
Agreement with OHM.

     The following table sets forth the unaudited combined pro forma results of
operations for the years ended December 31, 1993 and 1992, using the purchase
method of accounting as if such transaction had occurred on January 1, 1992:
 


                                                                      DECEMBER 31,

                                                                  --------     --------
                                                                  (IN THOUSANDS, EXCEPT
                                                                     PER SHARE DATA)
                                                                         
        Gross revenues..........................................  $141,669     $187,981
        Net revenues............................................   113,656      158,462
        Operating income (loss).................................     7,511       (3,785)
        Income (loss) from continuing operations................     3,546       (3,288)
        Income (loss) per share from continuing operation.......      0.42        (0.34)

 
     The pro forma combined results of operations for the years ended December
31, 1993 and 1992, are based upon certain assumptions and estimates which the
Company believes are reasonable. These pro forma combined results of operations
do not include the benefits of the synergies related to combining the two
companies. The pro forma combined results of operations for the year ended
December 31, 1992, exclude the impact of certain special charges aggregating
$12,203,000, net of income tax effects, recorded by the Division during 1992.
The pro forma combined results of operations for the years ended December 31,
1993 and 1992, may not be indicative of the operating results that actually
would have been reported had the transactions been consummated on January 1,
1992, nor are they necessarily indicative of the results which will be reported
in the future.
 
NOTE 3 -- DISCONTINUED OPERATIONS
 
     On May 4, 1993, the Company exchanged the capital stock of Industrial (the
Company's environmental cleaning and industrial maintenance services business)
together with 4,010,000 shares of its common stock to Brand for the assets and
liabilities of the Division pursuant to a Purchase Agreement among the Company,
Industrial, Brand, and WMI. Therefore, Industrial is being accounted for as
discontinued operations for the years ended December 31, 1993 and 1992.
 
     The provision for loss on disposition recorded in 1992, consisted of
estimated costs associated with the disposal and expected operating losses
through the date of disposition of the Company's environmental cleaning and
industrial maintenance services business. Gross revenues from CPS and MVIS for
the years ended December 31, 1993 and 1992, were $5,121,000 and $12,627,000,
respectively. The income from operations and provision for loss on disposition
of discontinued operations, which have been reflected in the consolidated
statement of operations for the year ended December 31, 1992, are presented net
of income taxes of $188,000 and an income tax benefit of $400,000, respectively.
Interest expense has been allocated to discontinued operations based on the
funds advanced to the Company by OHM for the acquisitions of CPS and MVIS.
Interest expense allocated to discontinued operations during the years ended
December 31, 1993 and 1992, amounted to $241,000 and $542,000, respectively.

NOTE 6 -- INCOME TAXES
 
     Effective January 1, 1992, the Company elected to adopt SFAS No. 109. The
cumulative effect of adopting SFAS No. 109 as of January 1, 1992, decreased net
income by $1,000,000, or $0.18 per share.
 
     At December 31, 1994, the Company has an alternative minimum tax ("AMT")
credit carryforward of $573,000. This carryforward resulted from the Company
generating AMT in 1990.
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes.

1%, and be utilized for working capital purposes. Interest on such loans will be
payable on a quarterly basis, and the aggregate principal amount of such loans
will mature on May 31, 1996. No amounts were outstanding under this revolving
credit agreement at December 31, 1994 or 1993.

NOTE 10 -- TRANSACTIONS WITH AFFILIATES
 
     The Company has, from time to time, provided asbestos abatement and related
services to affiliates of OHM on a subcontract basis. Revenues recognized from
these affiliates for such services were $1,377,000, $3,469,000, and $2,090,000
for 1994, 1993, and 1992, respectively. In addition, the Company also provided
environmental cleaning and industrial maintenance services to a subsidiary of
OHM during 1992. Revenues recognized from this affiliate were $1,871,000 and are
included in discontinued operations in the accompanying 1992 consolidated
statement of operations.
 
     In addition, the Company has, from time to time, provided asbestos
abatement and related services to Rust and certain of their affiliates on a
subcontract basis. Revenues recognized for such services were $4,509,000 and
$1,751,000 for the years ended December 31, 1994 and 1993, respectively. Also,
Rust and

certain of its affiliates provided scaffolding, disposal, demolition, and other
related services to the Company on a subcontract basis. The cost for such
services provided by Rust was $530,000 and $2,525,000 for the years ended
December 31, 1994 and 1993, respectively.
 
     From time to time in the normal course of business, the Company will seek
to recover amounts from customers in excess of the agreed-upon contract price,
based on customer-caused delays, errors in specifications and changes in design,
among other items. Revenues are recognized for amounts under pending claims when
management believes it is probable the claim will result in additional contract
revenues and the amount can be reliably estimated. At December 31, 1994, the
Company has a claim of $3.2 million outstanding against Rust on which it has
recognized a portion of the amount as revenue, based on management's anticipated
settlement.
 
     During the years ended December 31, 1994, 1993, and 1992, OHM charged the
Company $363,000, $93,000, and $475,000, respectively, for general liability and
other insurance coverages. The Company's employees were eligible to participate
in OHM's group insurance and other employee benefit plans prior to the Company's
acquisition in 1993 of the asbestos abatement division of Brand. The costs
charged to the Company by OHM for these employee benefits were $242,000 and
$540,000 for the years ended December 31, 1993, and 1992, respectively.
 
     Prior to the termination of the Cash Management Agreement with OHM on May
4, 1993, the Company advanced its excess cash to OHM and borrowed from OHM to
finance the expansion of its business. The Company was charged interest of
$591,000 and $1,384,000, for 1993, and 1992, respectively. The Company had
interest income of $316,000 and $1,074,000, for 1993, and 1992, respectively.
 
     OHM and its other subsidiaries also furnished to the Company financial,
administrative, legal and certain other staff functions and services prior to
the termination of the Management Services Agreement with OHM on May 4, 1993.
The Company believes that the charges for such services were made on a
reasonable basis and approximated what it would have incurred to obtain such
services on its own. The Company was charged $149,000, and $281,000 by OHM for
such services during the years ended December 31, 1993, and 1992, respectively.
In addition, the Company has reimbursed OHM for certain third-party charges paid
by OHM on the Company's behalf, such as letter of credit fees, insurance and
bonding costs, and legal fees.
 
NOTE 11 -- EMPLOYEE BENEFIT PLANS
 
     Effective October 1, 1992, the Company adopted the NSC Corporation
Retirement Savings Plan (the "Plan"). The Plan allows eligible employees to make
contributions, up to a certain limit, to a trust, on a tax-deferred basis under
Section 401(k) of the Internal Revenue Code. The Company may, at its discretion,
make profit-sharing contributions to the Plan out of its profits for the plan
years. Prior to October 1, 1992, the Company was a participating employer in the
OHM Corporation Retirement Savings Plan. The Company made matching contributions
of $21,000, and $28,000 to the plans described above during 1993, and 1992.
During 1994, no contributions were made.
 
     The Company's subsidiary, NSC, has certain union employees which are
covered by union-sponsored, collectively bargained, multi-employer retirement
plans. Contributions to the plans were $2,379,000, $1,500,000, and $1,002,000
for 1994, 1993, and 1992 respectively.
 
NOTE 12 -- LITIGATION, COMMITMENTS AND CONTINGENCIES
 
     The nature and scope of the Company's business bring it into regular
contact with the general public, a variety of businesses and government
agencies. Such activities inherently subject the Company to the hazards of
litigation, which are defended in the normal course of business. While the
outcomes of all claims are not clearly determinable at the present time,
management has recorded an estimate of any losses it expects to incur in
connection with the resolution of the claims.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     Effective November 1, 1992, the Company's primary auto liability,
commercial general liability, and, in most states, its workers' compensation
liability insurance coverages were issued under an arrangement with an insurance
carrier pursuant to which the Company effectively self-insures such primary
coverages. Above the respective primary policy limits, the Company has obtained
commercial excess/umbrella and excess workers' compensation liability stop loss
coverages on a fully insured basis. Prior to November 1, 1992, the Company
obtained insurance coverages through its participation in OHM's general
insurance program pursuant to the Management Services Agreement (see Note 10-
Transactions with Affiliates), with OHM dated May 1, 1990, and through other
external sources. The Company has recorded an estimate of the loss it expects to
ultimately incur under its insurance arrangements.
 
     The Company occupies office space and utilizes equipment in various
locations under operating leases. Rental expense under operating leases amounted
to $730,000, $455,000, and $193,000 for 1994, 1993, and 1992, respectively. The
lease agreements generally contain renewal provisions and escalation clauses.
Future minimum lease payments under noncancelable operating leases as of
December 31, 1994 are: 1995, $505,000; 1996, $186,000; 1997, $58,000; and 1998,
$9,000.
 
     The Company had $19,017,000 and $18,267,000 letters of credit outstanding
at December 31, 1994 and 1993, respectively. These letters of credit were issued
primarily in support of the Company's insurance programs.
 
NOTE 13 -- MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK
 
     During 1994 and 1993, no single customer accounted for more than 10% of the
Company's consolidated gross revenues. During 1992, the Company performed
various projects for Swig, Weiler & Arnow Management Co., Inc. which accounted
for approximately 14% of the Company's consolidated gross revenues.
 
     The Company provides asbestos abatement and related services to commercial,
institutional, and industrial clients with properties located throughout the
United States. The Company's commercial, institutional, and industrial clients
constituted 48%, 22%, and 30% of gross revenues as of December 31, 1994. The
Company generally invoices its customers as the work is being performed and does
not require collateral.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
NSC Corporation
 
     We have audited the accompanying consolidated balance sheets of NSC
Corporation and subsidiaries as of December 31, 1994 and 1993, and the related
consolidated statements of operations, changes in stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1994. Our
audits also include the financial statement schedule listed in the Index at Item
14(a). These financial statements and schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
NSC Corporation and subsidiaries at December 31, 1994 and 1993, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1994, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial 
statement schedule, when considered in relation to the basic financial 
statements taken as a whole, presents fairly in all material respects the 
information set forth therein.
 
     As discussed in Note 6 to the financial statements, in 1992 the Company 
changed its method of accounting for income taxes.
