                             UNICCO SERVICE COMPANY

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 29, 1998

(1) INTERIM FINANCIAL STATEMENTS

These condensed consolidated financial statements include the accounts of UNICCO
Service Company ("UNICCO" or the "Company") and its wholly-owned subsidiaries
for the period subsequent to October 17, 1997. Prior to that time, the financial
statements were prepared on a combined basis as all entities within the
consolidated group (the "Group") had been owned, managed and controlled by
common shareholders (see Note 2). All significant intercompany transactions have
been eliminated.

In the opinion of management, the accompanying unaudited condensed consolidated
financial statements include all adjustments consisting only of normal recurring
accruals necessary for a fair presentation of the financial position of the
Company and its subsidiaries at March 29, 1998 and the results of their
operations for the three and nine month periods ended March 29, 1998 and March
30, 1997, respectively and their cash flows for the nine month periods ended
March 29, 1998 and March 30, 1997.

Certain information and footnote disclosures normally included in financial
statements, prepared in accordance with generally accepted accounting
principles, have been condensed or omitted as allowed by Regulation S-X, Article
10. The accompanying, unaudited condensed consolidated financial statements
should be read in conjunction with the Company's combined financial statements
for the year ended June 29, 1997 in its Registration Statement on Form S-4 as
filed with the Securities and Exchange Commission and declared effective on
February 6, 1998.

Certain information in the accompanying 1997 condensed consolidated statements
of operations has been reclassified to conform to the 1998 presentation.

(2) REFINANCING

On October 17, 1997, UNICCO and certain of its affiliates consummated a $105
million Senior Subordinated Note offering (the "Notes") and entered into a $45
million Amended Credit Facility. The net proceeds from the Note offering and the
Amended Facility were used to repay approximately $84.8 million of indebtedness
under the Group's existing credit facilities and $19.7 million of certain other
indebtedness, fees and expenses incurred in connection with such financing. The
Notes mature on October 15, 2007. The Notes are not redeemable prior to October
15, 2002. Thereafter, the Notes are subject to redemption at any time at the
option of the issuers at redemption prices set forth in the Notes. Interest on
the Notes accrues at the rate of 9 7/8% per annum and is payable semi-annually
in arrears on April 15 and October 15 of each year, commencing on April 15,
1998. The payment of principal and interest on the Notes is subordinated in
right to the prior payment of all Senior Debt, as defined in the Indenture under
which the Notes were issued.

    Upon the occurrence of a change in control, as defined, the issuers are
obligated to make an offer to each holder of the Notes to repurchase all or any
part of such holders' Notes at an offer price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest. The covenants under
the Notes and the Amended Facility include limitations on certain sales of
assets, certain payments of dividends and incurrence of debt, certain mergers
and acquisitions and certain transactions with affiliates. With respect to the
Amended Facility, the Company is required to maintain certain financial ratios
which become more stringent over the term of the facility.

    During the second quarter of fiscal 1998, the Company recorded an
extraordinary loss of $3.0 million, net of state tax benefit related to the
refinancing discussed above. A total of $2.0 million of the loss was
attributable to the write-off of unamortized deferred financing costs in
connection with the refinancing of the Company's indebtedness in October 1997. A
total of $1.0 million of the extraordinary loss was attributable to the payment
of $11 million in October 1997 to settle certain indebtedness incurred in
connection with the June 1996 Ogden acquisition. The book value of such
indebtedness on the Company's balance sheet at the settlement date (October 17,
1997) was $10.0 million.

    In connection with the Note offering, the shareholders of UNICCO contributed
their ownership interests in USC, Inc. to UNICCO. As a result, all of the
operations of the Group are conducted through UNICCO and its wholly-owned
subsidiaries. This transaction 




                                       6


<PAGE>   7

was accounted for in a manner similar to that in pooling of interests accounting
with the assets and liabilities being recorded at their historical cost due to
the exchange of stock occurring between entities under common control. Further,
in connection with the contribution of ownership interests, USC, Inc. and its
subsidiaries elected to change to the cash basis of accounting for income tax
purposes, consistent with the basis followed by UNICCO. In connection with such
change, the Company recorded deferred tax assets and liabilities of $1.3 million
and $1.3 million, respectively. In addition, based upon a review of all
available evidence, management recorded a valuation allowance associated with
the deferred tax assets of $.9 million.

(3) CONDENSED CONSOLIDATING FINANCIAL INFORMATION OF GUARANTOR SUBSIDIARIES

The Notes are guaranteed, fully, unconditionally and jointly and severally, by
each of UNICCO's directly and indirectly wholly-owned domestic subsidiaries.
UNICCO's wholly-owned Canadian subsidiary ("UFSCC") is not a guarantor of this
debt. Separate financial statements of the guarantor subsidiaries and of UNICCO
Finance Corp., a wholly-owned restricted-purpose subsidiary which is the
co-issuer of the Notes, are not presented because management has determined that
they would not be material to investors. However, condensed consolidating
financial information as of June 29, 1997 and March 29, 1998 and the three and
nine month periods ended March 29, 1998 are presented. The following presents
condensed combining consolidating financial information for (i) UNICCO only,
(ii) the guarantor subsidiaries on a combined basis, (iii) the nonguarantor
subsidiary - UFSCC - and (iv) the Company on a consolidated basis.

(4) LITIGATION

     In the ordinary course of business, the Company is party to various types
of litigation. The Company believes it has meritorious defenses to all claims,
and, in its opinion, all litigation currently pending or threatened will not
have a material adverse effect on the Company's financial position or results of
operations.

(5) ACQUISITION

     Effective February 1, 1998, the Company acquired 100% of the outstanding
common stock of American Building Services, Inc. ("ABS"). The acquisition was
accounted for as a purchase, and accordingly, the operations of ABS are included
in the accompanying financial statements from the effective date. The ABS
acquisition is not material to the Company's operations and the purchase price
has been allocated on a preliminary basis.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

     During the third quarter of fiscal 1998, the Company began to report
revenues and expenses based upon its regional operations. Revenue comparisons
for the period presented are based upon these classifications. The Company's
regional operations include Northeast, Eastern, Southeast, Southwest, Midwest,
Canada and Hawaii.

COMPARISON OF THREE MONTH PERIODS ENDED MARCH 29, 1998 AND MARCH 30, 1997

     REVENUES Revenues for the third quarter of fiscal 1998, which ended March
29, 1998, were $139.3 million compared to $134.3 million for the third quarter
of fiscal 1997, which ended March 30, 1997, an increase of $5.0 million or 3.7%.
This increase was primarily attributable to revenue increases in the Company's
Eastern Region ($3.5 million), Midwest Region ($1.8 million) and Canadian Region
($1.6 million). Such increases resulted from services performed under new
contracts and the impact of a full year's revenue from contracts acquired in the
prior year. These increases were partially offset by a $1.9 million revenue
decrease associated with the loss of a contract in May 1997 which generated
revenues in all of the Company's regions, excluding Canada.

     COST OF REVENUES Cost of revenues for the third quarter of fiscal 1998 were
$124.2 million, or 89.2% of revenues, compared to $121.4 million, or 90.4% of
revenues, for the third quarter of fiscal 1997. This improvement was primarily
due to a decrease in direct labor as a percentage of revenues as well as
favorable trends in insurance costs. Direct labor as a percentage of revenues
was 56.4% in the 1998 period, compared to 58.9% in the comparable quarter in
fiscal 1997. This improvement was primarily attributable to tighter management
of labor costs.

     GROSS PROFIT As a result of the foregoing, gross profit for the third
quarter of fiscal 1998 was $15.2 million, or 10.9% of revenues, compared to
$12.9 million, or 9.6% of revenues, for the comparable period in fiscal 1997.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES Selling, general and
administrative expenses for the third quarter of fiscal 1998 were $9.3 million,
or 6.7% of revenues, compared to $8.3 million, or 6.2% of revenues, for the
third quarter of fiscal 1997. The increase of $1.0 million was primarily
attributable to incremental costs associated with the assimilation of the
facility services business acquired from Ogden Corporation ("Ogden") in June
1996. Salaries and wages and payroll-related costs increased $1.0 million as a
result of the additional headcount required to support the acquired Ogden
business as well as the impact of annual salary adjustments effective July 1,
1997. Additionally, office and occupancy costs increased $.5 million between the
comparable periods, primarily as a result of increased computer lease costs,
depreciation expense, temporary help, relocation expense and recruiting
expenses. Professional fees, primarily consisting of external programming
related costs, decreased $.5 million between the comparable periods as a result
of the completion of the systems integration of the acquired Ogden business
during the last quarter of fiscal 1997.

     AMORTIZATION OF INTANGIBLE ASSETS Amortization expense was $1.2 million in
the third quarter of fiscal 1998 and fiscal 1997.

     INCOME FROM OPERATIONS As a result of the foregoing, income from operations
for the third quarter of fiscal 1998 was $4.7 million, or 3.4% of revenues,
compared to $3.4 million, or 2.6% of revenues for the third quarter of fiscal
1997.

     EBITDA As a result of the foregoing, EBITDA for the third quarter of fiscal
1998 was $6.5 million, or 4.7% of revenues, compared to $5.2 million, or 3.9% of
revenues, for the third quarter of fiscal 1997. EBITDA is defined as earnings
before provision 



                                       11


<PAGE>   12
for income taxes, interest expense, interest income and depreciation and
amortization. EBITDA as presented may not be comparable to similarly titled
measures used by other companies, depending upon the non-cash charges included.
When evaluating EBITDA, investors should consider that EBITDA (i) should not be
considered in isolation but together with other factors which may influence
operating and investing activities, such as changes in operating assets and
liabilities and purchases of property and equipment; (ii) is not a measure of
performance calculated in accordance with generally accepted accounting
principles; (iii) should not be construed as an alternative or substitute for
income from operations, net income or cash flows from operating activities in
analyzing the Company's operating performance, financial position or cash flows;
and (iv) should not be used as an indicator of the Company's operating
performance or as a measure of its liquidity.

     INTEREST EXPENSE Interest expense for the third quarter of fiscal 1998 was
$2.9 million, or 2.1% of revenues, compared to $3.1 million, or 2.3% of
revenues, for the third quarter of fiscal 1997. The decrease resulted from lower
outstanding indebtedness during the third quarter of fiscal 1998.

     INCOME TAXES Provision for income taxes for the third quarter of fiscal
1998 was $0.3 million, or 14.9% of income before provision for income taxes and
extraordinary items, compared to $0.2 million, or 66.1% of income before
provision for income taxes and extraordinary items, for the third quarter of
fiscal 1997. The higher effective tax rate in the third quarter of fiscal 1997
resulted from the significant growth in the working capital of the Ogden
operations acquired at the end of fiscal 1996 and the Company's previous
election to be a cash basis taxpayer.

     NET INCOME (LOSS) As a result of the foregoing, net income for the third
quarter of fiscal 1998 was $1.6 million, or 1.2% of revenues, compared to net
income of $.1 million, or .1% of revenues, for the third quarter of fiscal 1997.

COMPARISON OF NINE MONTH PERIODS ENDED MARCH 29, 1998 AND MARCH 30, 1997

     REVENUES Revenues for the nine months ended March 1998 were $411.5 million
compared to $397.9 million for the comparable period of 1997, an increase of
$13.6 million, or 3.4%. This increase was primarily attributable to revenue
increases in the Eastern Region ($8.0 million), the Canadian Region ($4.8
million), the Southwest Region ($2.2 million), Southeast Region ($1.5 million),
Northeast Region ($1.4 million), Midwest Region ($1.3 million) and Hawaii ($.4
million). Such increases resulted from services performed under new contracts
and the impact of a full year's revenue from contracts acquired in the prior
year. These increases were partially offset by a $4.0 million revenue decrease
associated with the loss of a contract in May 1997 which generated revenues in
all of the Company's regions, excluding Canada and a decrease in revenues in the
Security Division of ($2.0 million) which was primarily due to revenues
generated from significant one time work for a customer in 1997 of approximately
$1.4 million. 

     COST OF REVENUES Cost of revenues for the nine months ended March 1998 were
$368.5 million, or 89.6% of revenues, compared to $358.8 million, or 90.2% of
revenues, for the comparable period. This improvement was primarily due to a
decrease in direct labor as a percentage of revenues as well as favorable trends
in insurance costs. Direct labor as a percentage of revenues was 56.9% in the
1998 period, compared to 58.8% in the comparable 1997 period. This improvement
was primarily attributable to tighter management of direct labor costs.

     GROSS PROFIT As a result of the foregoing, gross profit for the nine months
ended March 1998 was $43.0 million, or 10.5% of revenues, compared to $39.1
million, or 9.8% of revenues, for the comparable period.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES Selling, general and
administrative expenses for the nine months ended March 1998 were $26.9 million,
or 6.5% of revenues, compared to $22.8 million, or 5.7% of revenues for the
comparable period. The increase of $4.1 million was primarily attributable to
incremental costs associated with the Ogden acquisition. The majority of these
incremental costs were incurred after the second quarter of fiscal 1997.
Salaries and wages increased $2.3 million as a result of the additional
headcount required to support the acquired Ogden business as well as the impact
of annual salary adjustments effective July 1, 1997. Additionally, office and
occupancy costs increased $1.7 million between the comparable periods, primarily
as a result of increased computer lease costs, depreciation expense, temporary
help, relocation expense and recruiting expenses.

     AMORTIZATION OF INTANGIBLE ASSETS Amortization expense was $3.6 million in
each of the nine month periods of fiscal 1998 and 1997.

     INCOME FROM OPERATIONS As a result of the foregoing, income from operations
for the nine months ended March 1998 was $12.5 million, or 3.0% of revenues,
compared to $12.7 million, or 3.2% of revenues, for the comparable period.

     EBITDA As a result of the foregoing, EBITDA for the nine months ended March
1998 was $17.9 million, or 4.3% of revenues, compared to $18.0 million, or 4.5%
of revenues, for the nine months ended March 1997.

     INTEREST EXPENSE Interest expense for the nine months ended March 1998 was
$8.7 million, or 2.1% of revenues, compared to $8.5 million, or 2.1% of
revenues, for the nine months ended March 1997. The increase resulted from
higher borrowings under the Company's revolving credit facilities during the
first quarter of fiscal 1998 as compared to the first quarter of fiscal 1997.
Average monthly borrowings under these facilities were $51.0 million for the
first quarter of 1998, as compared to $20.5 million for the comparable 1997
period.

     INCOME TAXES In October 1997, USC, Inc. and its subsidiaries elected to
change to the cash basis of accounting for income tax purposes, consistent with
the basis followed by UNICCO Service Company. As a result, the Company recorded
deferred tax assets and liabilities of $1.3 million and $1.3 million,
respectively. In addition, based upon a review of all available evidence,
management recorded a valuation allowance associated with the deferred tax
assets of $.9 million.

     EXTRAORDINARY LOSS During the second quarter of fiscal 1998, the Company
recorded an extraordinary loss of $3.0 million, net of state tax benefit. A
total of $2.0 million of the loss was attributable to the write-off of
unamortized deferred financing costs in connection with the refinancing of the
Company's indebtedness in October 1997 (see Note 2 to the accompanying Condensed
Consolidated Financial Statements). A total of $1.0 million of the extraordinary
loss was attributable to the payment of $11 million in October 1997 to settle
certain indebtedness incurred in connection with the June 1996 Ogden
acquisition. The book value of such indebtedness on the Company's balance sheet
at the settlement date (October 17, 1997) was $10.0 million.

     NET INCOME (LOSS) As a result of the foregoing, net loss for the nine
months ended March 1998 was $.8 million, or .2% of revenue, compared to net
income of $1.7 million or .4% of revenue, for the comparable period of 1997.

LIQUIDITY AND CAPITAL RESOURCES

     For the nine months ended March 29, 1998, the Company's cash balance did
not materially change. A total of $3.7 million of cash was provided by operating
activities and investing activities which consisted of $7.1 million of net cash
provided by operating activities and $3.4 million used for investing activities.
Investing activities included cash of $2.2 million for an acquisition in
February 1998. Net cash used in financing activities during the period was $3.7
million. In October 1997, the Company consummated an offering of $105 million of
9 7/8%. Senior Subordinated Notes due 2007. Proceeds from the offering, net of
bond discount and expenses, were $101.2 million. Proceeds were used to repay
long-term debt of $52.4 million and outstanding borrowings under the Company's
prior revolving credit facilities of $48.8 million.

     For the nine months ended March 1997, $39.3 million of cash was used in
operating and investing activities which consisted of $37.6 million of cash used
in operating activities and $1.7 million used in investing activities. The cash
used in operating activities was primarily to fund the working capital
requirements related to the Ogden acquisition, which occurred on June 28, 1996.
Net cash provided by financing activities during the period was $39.3 million,
which primarily represented borrowings under the Company's $48 million line of
credit.

     Capital expenditures were $1.4 million and $1.8 million, respectively, for
the nine month periods ended March 1998 and l997. The Company's operations do
not generally require material investment in capital assets. The Company expects
that its capital expenditure requirements will not increase materially during
the fourth quarter of fiscal 1998.

     The Company is party to an amended revolving credit facility (the "Credit
Facility") under which the Company may borrow up to $45.0 million for working
capital and general corporate purposes, subject to certain conditions. There
were no borrowings under the Credit Facility as of March 29, 1998. The Credit
Facility, the Indenture governing the Company's Senior Subordinated Notes due
2007 and the terms of the Company's other subordinated indebtedness include
certain financial and operating covenants which, among other things, restrict
the ability of the Company to incur additional indebtedness, make investments
and take other actions. The ability of the Company to meet its debt service
obligations will be dependent upon the future performance of the Company, which
will be impacted by general economic conditions and other factors.

     The Company's principal capital requirements are to service the Company's
indebtedness, for working capital and, to a lesser extent, to fund capital
expenditures. The Company believes that its cash flow from operations, together
with its borrowing capacity under the Credit Facility, will be sufficient to
meet such requirements as they now exist.
