                              UNICCO FINANCE CORP.
 
           THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
                  TIME, ON __________, 1998, UNLESS EXTENDED.
 
    UNICCO Service Company, a Massachusetts business trust, and UNICCO Finance
Corp., a Delaware corporation (together, the "Issuers"), hereby offer, upon the
terms and subject to the conditions set forth in this Prospectus and the
accompanying letter of transmittal (the "Letter of Transmittal" and, together
with this Prospectus, the "Exchange Offer"), to exchange an aggregate of up to
$105,000,000 principal amount of 9 7/8% Senior Subordinated Notes due 2007,
Series B (the "Exchange Notes"), which have been registered under the Securities
Act of 1933, as amended (the "Securities Act"), for an identical face amount of
the issued and outstanding 9 7/8% Senior Subordinated Notes due 2007 (referred
to individually as the "144A Notes," "IAI Notes" and "Reg S Notes"; collectively
as the "Series A Notes"; and, together with the Exchange Notes, the "Notes") of
the Issuers from the Holders (as defined herein) thereof in integral multiples
of $1,000 principal amount. As of the date of this Prospectus, there are
$105,000,000 in aggregate principal amount of the Series A Notes outstanding.
The terms of the Exchange Notes are identical in all material respects to the
Series A Notes, except that the Exchange Notes have been registered under the
Securities Act, and therefore will not bear legends restricting their transfer
described in the Registration Rights Agreement (as defined herein), which
provisions generally will terminate as to all of the Notes upon the consummation
of the Exchange Offer. The Exchange Notes will be obligations of the Issuers
evidencing the same indebtedness as the Series A Notes, and will be entitled to
the benefits of the same Indenture (as defined herein). See "The Exchange
Offer."
 
    Interest on the Exchange Notes will be payable semi-annually in arrears on
April 15 and October 15 of each year, commencing on April 15, 1998. The Exchange
Notes will mature on October 15, 2007. The Exchange Notes are redeemable at any
time on or after April 1, 2002 at the option of the Issuers, in whole or in
part, at the redemption prices set forth herein, together with accrued and
unpaid interest, if any, to the date of redemption. Upon the occurrence of a
Change of Control (as defined herein), each holder of the Exchange Notes may
require the Issuers to purchase all or a portion of such holder's Exchange Notes
at a purchase price equal to 101% of the principal amount thereof, together with
accrued and unpaid interest, if any, to the date of purchase. See "Description
of the Exchange Notes -- Repurchase at the Option of the Holders."
 
    The Exchange Notes will be unsecured senior subordinated obligations of the
Issuers and, as such, will be subordinated in right of payment to all existing
and future senior indebtedness of the Issuers. The Exchange Notes will rank pari
passu in right of payment with all other existing and future senior subordinated
indebtedness, if any, of the Issuers, and senior in right of payment to all
existing and future subordinated indebtedness, if any, of the Issuers. The
Exchange Notes will be guaranteed, jointly and severally, on a senior
subordinated basis (the "Guarantees") by certain of the Issuers' subsidiaries
(the "Guarantors" and, together with the Issuers, the "Company"). The Guarantees
will be unsecured senior subordinated obligations of the Guarantors and will be
subordinated to all existing and future Senior Debt (as defined herein) of the
Guarantors. See "Description of the Exchange Notes -- Subsidiary Guarantees." As
of September 28, 1997, on a pro forma basis after giving effect to the
Transactions (as defined herein), the Company and the Guarantors would have had
approximately $3.4 million in aggregate principal amount of Senior Debt
outstanding.
 
      SEE "RISK FACTORS," BEGINNING ON PAGE 12 FOR A DISCUSSION OF CERTAIN
FACTORS THAT SHOULD BE CONSIDERED BY PARTICIPANTS IN THE EXCHANGE OFFER.
                            ------------------------
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
 
UNTIL            , 1998 (90 DAYS AFTER THE DATE OF THIS PROSPECTUS), ALL DEALERS
      EFFECTING TRANSACTIONS IN THE REGISTERED SECURITIES, WHETHER OR NOT
  PARTICIPATING IN THIS DISTRIBUTION, MAY BE REQUIRED TO DELIVER A PROSPECTUS.
 
               THE DATE OF THIS PROSPECTUS IS            , 1997.
<PAGE>   4
 
     The Company will accept for exchange any and all validly tendered Series A
Notes on or prior to the Expiration Date (as defined herein). Tenders of Series
A Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on
the Expiration Date; otherwise such tenders are irrevocable. The Exchange Offer
is not conditioned upon any minimum principal amount of Series A Notes being
tendered for exchange. For certain conditions to the Exchange Offer, see "The
Exchange Offer -- Conditions."
 
     The Series A Notes were offered and sold on October 17, 1997 in a
transaction not registered under the Securities Act in reliance upon an
exemption from the registration requirements thereof. In general, the Series A
Notes may not be offered or sold unless registered under the Securities Act,
except pursuant to an exemption from, or in a transaction not subject to, the
Securities Act.
 
     The Exchange Notes are being offered hereby in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreement. The
Company has agreed to pay the expenses of the Exchange Offer. Based on
interpretations by the staff of the Securities and Exchange Commission (the
"Commission") set forth in no-action letters issued to third parties, the
Company believes that the Exchange Notes issued pursuant to the Exchange Offer
in exchange for Series A Notes may be offered for resale, resold or otherwise
transferred by any person in whose name Series A Notes are registered on the
books of the Company or any other person who has obtained a properly completed
bond power from the registered holder (a "Holder") thereof (other than any such
Holder that is an "affiliate" of the Company within the meaning of Rule 405
promulgated under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such Holder's business and
such Holder does not intend to participate and has no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes. In some cases, certain broker-dealers may be required to deliver
a prospectus in connection with the resale of such Exchange Notes.
 
     This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with any resale of Exchange Notes
received in exchange for such Series A Notes where such Series A Notes were
acquired by such broker-dealer for its own account as a result of market-making
activities or other trading activities (other than Series A Notes acquired
directly from the Company). The Company has agreed that it will make this
Prospectus available to any broker-dealer for use in connection with any such
resale.
 
     Prior to this Exchange Offer, there has been no public market for the
Notes. If a market for the Exchange Notes should develop, the Exchange Notes
could trade at a discount from their principal amount. The Company does not
intend to list the Exchange Notes on any securities exchange nor does the
Company intend to apply for quotation of the Exchange Notes on the NASDAQ
National Market or other quotation system. The Initial Purchaser (as defined
herein) has indicated to the Company that it intends to make a market in the
Notes, but is not obligated to do so and such market-making activities may be
discontinued at any time. As a result, no assurance can be given that an active
trading market for the Exchange Notes will develop.
 
     The Exchange Notes issued pursuant to this Exchange Offer will be issued in
the form of a Global Exchange Note (as defined herein), which will be deposited
with, or on behalf of, The Depository Trust Company (the "Depository" or "DTC")
and registered in its name or in the name of Cede & Co., its nominee. Beneficial
interests in the Global Exchange Note representing the Exchange Notes will be
shown on, and transfers thereof will be effected through, records maintained by
DTC and its participants. Notwithstanding the foregoing, Series A Notes held in
certificated form will be exchanged solely for Certificated Exchange Notes (as
defined herein). After the initial issuance of the Global Exchange Note,
Certificated Exchange Notes will be issued in exchange for the Global Exchange
Note only on the terms set forth in the Indenture. See "Description of the
Exchange Notes -- Book-Entry, Delivery and Form."

detailed information, including "Risk Factors" and the Combined Consolidated
Financial Statements and notes thereto, appearing elsewhere in this Prospectus.
Unless the context otherwise requires, references herein to "UNICCO" or the

                                  THE COMPANY
 
     Founded in 1949, UNICCO is a leading provider of integrated facilities
services to a broad base of industrial, commercial and institutional clients
throughout the United States and Canada. The Company offers an extensive array
of commercial, operational and administrative services to its customers,
providing a single source solution for those services that can be more
cost-effectively and efficiently outsourced. Services offered by the Company
include industrial and mechanical engineering, plant operations, custodial and
maintenance services, security services and administrative services. UNICCO has
developed a reputation for quality through nearly 50 years of service to its

market share in many of its operating regions through a combination of internal
growth and strategic acquisitions. The Company believes that the breadth of its
services, its reputation for quality and its significant market presence
position it to provide a single source facilities management solution to local,
multi-location and national customers. The Company has over 19,000 employees
servicing approximately 900 customers, including 29 of the Fortune 100
companies, at approximately 3,000 customer locations. Throughout its history,
the Company has generated a record of growth and consistent profitability. For
the fiscal year ended June 29, 1997, the Company's net income, revenues and
EBITDA (as defined) were $1.2 million, $533.9 million and $22.2 million,
respectively. For the three month period ended September 28, 1997, such amounts
were $578,000, $134.7 million and $5.5 million, respectively.

     The Company believes that opportunities for growth exist in each SBU,
particularly in the Industrial and Education/Healthcare/Government sectors, as a
result of the trend toward outsourcing non-core business functions to a single
source provider. Outsourcing frees the customer from the considerable
administrative and overhead burdens of hiring, training, compensating and
supervising a large, often unionized, labor force that is performing non-core
functions. UNICCO has responded to its customers' outsourcing strategies by
providing an expanded array of services that has evolved from traditional
custodial and building maintenance to higher value added services.
 
     The Company has a customer base of approximately 900 accounts, with no
single customer accounting for more than 3% of revenues during fiscal 1997. The
Company's customer retention rate historically has been high. Customers
representing approximately 75% of fiscal 1997 revenues have been UNICCO
customers for an average of more than six years (excluding revenues and
customers resulting from the Ogden Acquisition (as defined) in June 1996). On a
combined basis, the Company and Ogden (as defined) have serviced their 20
largest customers, including the former Ogden customers, for an average of 10
years. In addition, the Company has successfully retained over 90% of the
customers acquired in the Ogden Acquisition. UNICCO believes that its strong
reputation and long-term relationships with these customers is a result of a
high level of customer satisfaction. The Company also believes that these
established relationships enhance the Company's knowledge of its customers'
needs and place UNICCO in a strong competitive position to bid on and win new
business opportunities with these customers.

                               BUSINESS STRENGTHS
 
     UNICCO's revenues have increased through a combination of internal growth
and strategic acquisitions. The Company's growth, and its emergence as a leader
in the facilities services market in the United States and Canada, are
attributable to a number of factors, including the following:
 
     High Customer Retention.  The Company benefits from a large, stable base of
customers, including 29 of the Fortune 100 companies, 60 of the Fortune 500
companies and some of the country's most prestigious educational institutions.
The Company's customer base, together with its high customer retention rate,
have provided stable, recurring revenues and have contributed to the Company's
record of consistent profitability.
 
     Established Reputation.  The Company has established a reputation for
quality through almost 50 years of experience in providing dependable, complex
facilities services solutions in a changing business environment. The Company
believes that its established reputation and the breadth of its services have
allowed it to further penetrate its existing customer base as well as attract
new business. The Company plans to enhance its reputation for dependability and
technical expertise by pursuing the highest levels of industry accreditation.
 
     Singular Focus on Facilities Services.  The Company is focused exclusively
on providing facilities services solutions to its customers, unlike many of its
larger competitors for whom facilities management is an adjunct to their primary
business or one of many other unrelated lines of business. The Company believes
that this exclusive focus gives it a competitive advantage in delivering
dependable, high quality services.
 
     Established North American Presence.  The Company provides services
throughout the United States and Canada from 16 regional offices to customers in
over 40 states and each of the Canadian provinces. The Company believes that it
can leverage this infrastructure to support the marketing and delivery of
services to new customers in strategic geographic areas and to obtain additional
business from major companies that seek to utilize a single source provider
nationwide.
 
     Effective Human Resources and Labor Relations Management.  UNICCO
successfully manages a large and diverse work force of over 19,000 full and
part-time employees. The Company places a major emphasis on attracting,
training, managing, motivating and retaining the human resources necessary to
meet its existing and future business needs. The Company's extensive industry
experience and sophisticated computer-based costing models allow it to
accurately assess the labor requirements of new contracts. UNICCO seeks to
efficiently integrate its customers' existing workforce, thereby minimizing the
transitional issues typically associated with contract inception. In addition,
the Company believes that its experience in managing both union and non-union
work forces has enhanced its ability to grow its business.
 
     Experienced Management Team.  The Company's senior management team has an
average of 20 years of experience in the facilities services industry. The
Company benefits from the quality and depth of its management personnel, who are
dedicated to building customer relationships and delivering quality services to
meet and exceed its customers' needs. Additionally, management has developed
sophisticated databases and costing systems to forecast expenses for individual
customers' service requirements across a variety of service lines. These
proprietary databases enhance UNICCO's ability to effectively price and compete
for customers and contracts.
 
     Successful Acquisition History.  Throughout its 50-year history, UNICCO has
benefited from several successful strategic acquisitions. The Company has
completed three acquisitions since 1990, incorporating operations with revenues
of approximately $20 million, $5 million and $389 million in 1990, 1992 and
1996, respectively. The Company believes that its successful integration of
these acquisitions has positioned it to take advantage of opportunities for
further consolidation within the facilities services industry.

                             THE COMPANY'S STRATEGY
 
     The Company's objective is to enhance its position as a leading provider of
facilities services solutions. The Company's strategy to meet this objective
includes the following initiatives:
 
     Providing Integrated Facilities Solutions.  UNICCO believes that an
attractive opportunity exists to expand the scope of work performed for existing
customers. Cross-selling new services to existing customers represents a
cost-effective method for the Company to achieve revenue growth. The Company
seeks to create partnerships with its customers that enable it to capitalize on
the trend toward outsourcing to single source providers. As part of this
strategy, the Company intends to focus its efforts on increasing the proportion
of its business devoted to delivering higher value added services to its
customers.
 
     Leveraging its National Presence.  UNICCO has established a significant
presence throughout the United States and Canada. The Company believes that it
can substantially increase the number of multi-location and national accounts it
serves by leveraging its existing infrastructure to support the marketing and
delivery of bundled services to new customers that operate multiple locations.
 
     Capitalizing on Outsourcing Initiatives.  The Company believes that it is
well positioned to capitalize on favorable trends in a growing number of
industries toward outsourcing of non-core business functions. Many companies
have increased the volume and types of services they outsource in order to free
their human and capital resources to better focus on their strategic business
initiatives. The Company believes that its established reputation and the
breadth of its services enhance its ability to attract this potential business.
 
     Strategic Business Development.  Through its recent organization into the
four SBUs, the Company is focused on developing specific operating and marketing
strategies targeted to the unique needs of its customers in diverse market
segments. Because of the diversity of UNICCO's existing and potential customer
base, the Company believes that it can position itself to attract higher value
added business by continuing to anticipate its customers' differing needs. The
Company believes that the SBU initiatives it has implemented will enable it to
more effectively leverage its resources to generate new clients and additional
contracts with existing clients.
 
     Growing through Selective Acquisitions.  UNICCO has successfully expanded
its business through internal growth and strategic acquisitions, including the
successful integration of the Ogden Acquisition, and intends to seek additional
opportunities to grow through selective acquisitions. The Company may pursue
acquisitions that add additional services and technical capabilities to market
to its existing customer base, or that facilitate strategic expansion of the
Company's customer base or complement its existing geographic coverage.
 
                             THE OGDEN ACQUISITION
 
     On June 28, 1996, the Company consummated the strategic acquisition (the
"Ogden Acquisition") of a substantial portion of the facilities services
business of Ogden Corporation ("Ogden"). The Ogden Acquisition expanded the
Company's geographic range to cover most of the United States and Canada. The
purchase price for the Ogden Acquisition was $62 million, of which $50 million
was paid in cash and $12 million was paid in the form of a subordinated
promissory note (the "Ogden Note"). The Ogden Note was repurchased from Ogden
for $11 million with a portion of the net proceeds of the Series A Notes. See
"Use of Proceeds" and "Business -- History of the Company; the Ogden
Acquisition."

                                 UNICCO FINANCE
 
     UNICCO Finance is a wholly-owned subsidiary of UNICCO that was incorporated
in Delaware in order to facilitate the Offering of the Series A Notes by serving
as a co-issuer of the Series A Notes. The Company believed that certain
prospective purchasers of the Series A Notes may have been restricted in their
ability to purchase debt securities of a Massachusetts business trust, such as
UNICCO, unless such debt securities were jointly issued by a corporation. UNICCO
Finance will not have any substantial operations or assets and will not have any
revenues. As a result, prospective participants in the Exchange Offer should not
expect UNICCO Finance to participate in servicing the interest and principal
obligations under the Exchange Notes. See "Description of the Exchange
Notes -- General."

                             Distribution." By executing the Letter of
                             Transmittal, each Holder will represent to the
                             Company that, among other things, the Holder or the
                             person receiving such Exchange Notes, whether or
                             not such person is the Holder, is acquiring the
                             Exchange Notes in the ordinary course of business
                             and that neither the Holder nor any such other
                             person intends to participate or has any
                             arrangement or understanding with any person to
                             participate in the distribution of such Exchange
                             Notes. In lieu of physical delivery of the
                             certificates representing Series A Notes, tendering
                             Holders may transfer Series A Notes pursuant to the
                             procedure for book-entry transfer as set forth
                             under "The Exchange Offer -- Procedures for

                             registered in the name of a broker, commercial

                             wishes to tender in the Exchange Offer should
                             contact such registered holder promptly and
                             instruct such registered holder to tender on such
                             beneficial owner's behalf. If such beneficial owner
                             wishes to tender on such beneficial owner's own
                             behalf, such beneficial owner must, prior to
                             completing and executing the Letter of Transmittal
                             and delivering the Series A Notes, either make
                             appropriate arrangements to register ownership of
                             the Series A Notes in such beneficial owner's name
                             or obtain a properly completed bond power from the
                             registered holder. The transfer of registered
                             ownership may take considerable time. See "The
                             Exchange Offer -- Procedures for Tendering."
 
Guaranteed Delivery
  Procedures...............  Holders of Series A Notes who wish to tender their
                             Series A Notes and whose Series A Notes are not
                             immediately available or who cannot deliver their
                             Series A Notes, the Letter of Transmittal or any
                             other documents required by the Letter of
                             Transmittal to the Exchange Agent (or comply with
                             the requirements for book-entry transfer) prior to
                             the Expiration Date must tender their Series A
                             Notes according to the guaranteed delivery
                             procedures set forth in "The Exchange Offer --
                             Guaranteed Delivery Procedures."
 
Federal Income Tax
  Consequences.............  The issuance of the Exchange Notes to Holders
                             pursuant to the terms set forth in this Prospectus
                             will not constitute an exchange for federal income
                             tax purposes. Consequently, no gain or loss would
                             be recognized by Holders upon receipt of the
                             Exchange Notes. See "The Exchange Offer -- Certain
                             Federal Income Tax Consequences of the Exchange
                             Offer."
 
Use Of Proceeds............  There will be no proceeds to the Company from the
                             exchange of Series A Notes pursuant to the Exchange
                             Offer.
 
Exchange Agent.............  State Street Bank and Trust Company is serving as
                             exchange agent (the "Exchange Agent") in connection
                             with the Exchange Offer. See "The Exchange
                             Offer -- Exchange Agent."
 
                     SUMMARY OF TERMS OF THE EXCHANGE NOTES
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Series A Notes (which they replace) except that (i) the Exchange Notes
have been registered under the Securities Act and, therefore, will not bear
legends restricting the transfer thereof, and (ii) the holders of Exchange Notes
generally will not be entitled to further registration rights under the
Registration Rights Agreement, which rights generally will be satisfied when the
Exchange Offer is consummated. The Exchange Notes will evidence the same debt as
the Series A Notes and will be entitled to the benefits of the indenture
pursuant to which the Series A Notes were issued (the "Indenture"). See
"Description of the Exchange Notes."

                             trust, and UNICCO Finance Corp., a Delaware

Guarantees.................  The Exchange Notes will be guaranteed by all of the
                             Company's existing
                             Domestic Restricted Subsidiaries (the
                             "Guarantors"), and all Domestic Restricted
                             Subsidiaries created or acquired by the Company in
                             the future.
 
Ranking....................  The Exchange Notes will be general unsecured
                             obligations of the Issuers and will be subordinated
                             in right of payment to all existing and future
                             Senior Debt of the Issuers. As of September 28,
                             1997, after giving pro forma effect to the
                             Transactions, the Issuers would have had
                             approximately $3.4 million of Senior Debt
                             outstanding, consisting of outstanding borrowings
                             under the Credit Facility. In addition, the Issuers
                             would have had $41.6 million of additional
                             borrowings available under the Credit Facility. See
                             "Use of Proceeds" and "Unaudited Pro Forma
                             Financial Data."
 
Optional Redemption........  Except as set forth below, the Exchange Notes will
                             not be redeemable at the option of the Issuers
                             prior to October 15, 2002. Thereafter, the Exchange
                             Notes will be subject to redemption at any time at
                             the option of the Issuers, in whole or in part, at
                             the redemption prices set forth herein, plus
                             accrued and unpaid interest and Liquidated Damages,
                             if any, thereon to the redemption date. In
                             addition, at any time prior to October 15, 2000,
                             the Issuers may redeem up to an aggregate of $33.0
                             million in principal amount of Exchange Notes at a
                             redemption price equal to 109.875% of the principal
                             amount thereof, plus accrued and unpaid interest
                             and Liquidated Damages, if any, thereon to the
                             redemption date, with the net cash proceeds of an
                             initial public offering of common equity of the
                             Company, provided that at least $72.0 million in
                             principal amount of Exchange Notes remains
                             outstanding immediately after the occurrence of
                             such redemption.
 
Change of Control..........  In the event of a Change of Control, the Issuers
                             will be required to make an offer to each holder of
                             Exchange Notes to repurchase all or any part of
                             such holder's Exchange Notes at a repurchase price
                             equal to 101% of the principal amount thereof, plus
                             accrued and unpaid interest and Liquidated Damages,
                             if any, thereon to the repurchase date.
 
Covenants..................  The Indenture contains certain covenants that,
                             among other things, limit the ability of the
                             Issuers and the Company's Restricted Subsidiaries
                             (as defined) to incur additional Indebtedness (as
                             defined), pay dividends, repurchase Equity
                             Interests (as defined) or make other Restricted
                             Payments (as defined), create Liens (as defined),
                             enter into transactions with Affiliates (as
                             defined), sell assets or enter into certain mergers
                             and consolidations. See "Description of the
                             Exchange Notes."

                             (i) the Issuers are not required to file the
                             Exchange Offer Registration Statement or permitted
                             to consummate the Exchange Offer because the
                             Exchange Offer is not permitted by applicable law
                             or Commission policy or (ii) in certain
                             circumstances, a Holder notifies the Company prior
                             to the 20th day following consummation of the
                             Exchange Offer that (a) it is prohibited by law or
                             Commission policy from participating in the
                             Exchange Offer, (b) it may not resell the Exchange
                             Notes acquired by it in the Exchange Offer to the
                             public without delivering a prospectus and the
                             prospectus contained in the Exchange Offer
                             Registration Statement

                             is not appropriate or available for such resales or
                             (c) it is a broker-dealer and owns Series A Notes
                             acquired directly from the Issuers or an affiliate
                             of the Issuers, the Issuers will file with the
                             Commission a shelf registration statement (the
                             "Shelf Registration Statement") to cover resales of
                             the Series A Notes by the Holders thereof who
                             satisfy certain conditions relating to the
                             provision of information in connection with the
                             Shelf Registration Statement.
 
                             The interest rate on the Notes is subject to
                             increase under certain circumstances if the Company
                             is not in compliance with its obligations under the
                             Registration Rights Agreement. See "Description of
                             the Exchange Notes -- Registration Rights;
                             Liquidated Damages."
 
Lack Of Prior Market For
The Exchange Notes.........  The Exchange Notes will be new securities for which
                             there is currently no established trading market.
                             The Company does not intend to apply for listing of
                             the Exchange Notes on any national securities
                             exchange or for quotation of the Exchange Notes on
                             any automated dealer quotation system. The Company
                             has been advised by the Initial Purchasers that
                             they presently intend to make a market in the
                             Exchange Notes, although they are under no
                             obligation to do so and may discontinue any market-
                             making activities at any time without notice.
                             Accordingly, no assurance can be given as to the
                             liquidity of the trading market for the Exchange
                             Notes or that an active public market for the
                             Exchange Notes will develop. If an active trading
                             market for the Exchange Notes does not develop, the
                             market price and liquidity of the Exchange Notes
                             may be adversely affected. If the Exchange Notes
                             are traded, they may trade at a discount from their
                             initial offering price, depending on prevailing
                             interest rates, the market for similar securities,
                             the performance of the Company and certain other
                             factors. See "Risk Factors -- Absence of Public
                             Market for Exchange Notes."
 
                                  RISK FACTORS
 
     Holders of the Series A Notes should carefully consider the matters set
forth under "Risk Factors," as well as the other information and financial
statements and data included in this Prospectus prior to deciding to tender
Series A Notes in the Exchange Offer.

- ---------------
(1) Fiscal 1996 was a 53-week year. As a result, the Company's results of
    operations for fiscal 1996 include approximately $1.0 million of payroll and
    payroll-related expenses attributable to the additional week of operations
    that were not billed in the period to customers with fixed price contracts.
    See "Management's Discussion and Analysis of Financial Condition and Results
    of Operations."
 
(2) For the years ended June 25, 1995 and June 30, 1996, the Company was not
    subject to federal and certain state income taxes as it had elected to be
    treated as a subchapter S corporation. For the year ended June 29, 1997,
    certain entities of the Company were taxed as C corporations through
    December 31, 1996, at which time they elected to be treated as subchapter S
    corporations. See Note 7 of Notes to the Company's Combined Consolidated
    Financial Statements.
 
(3) EBITDA is defined as earnings before provision for income taxes, interest
    expense, interest income and depreciation and amortization. EBITDA is
    presented because it is a widely accepted financial indicator of a leveraged
    company's ability to service and/or incur indebtedness and because
    management believes that EBITDA is a relevant measure of the Company's
    ability to generate cash without regard to the Company's capital structure
    or working capital needs. 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.
 
(4) EBITDA margin represents EBITDA as a percentage of revenues.
 
(5) Cash interest expense is defined as interest expense excluding amortization
    of deferred financing costs.
 
(6) Net debt is defined as total long-term debt minus cash as of the end of the
    period presented. EBITDA for the first quarter of fiscal 1998 has been
    annualized for the purposes of calculating this ratio.
 
(7) Pro forma interest expense reflects (i) $438,500 of amortization of deferred
    debt issuance costs related to the offering of the Series A Notes, (ii)
    $49,350 of amortization of original issue discount related to the Series A
    Notes, (iii) interest expense related to the Series A Notes and (iv)
    interest expense related to pro forma borrowings under the Credit Facility
    at an assumed interest rate of 7.63%, which is the interest rate that would
    have been applicable under the Credit Facility for the year ended June 29,
    1997. Pro forma interest expense for the three month period ended September
    28, 1997 was calculated in a similar fashion.
 
(8) For purposes of calculating the ratio of earnings to fixed charges, earnings
    consist of income before provision for income taxes, plus fixed charges.
    Fixed charges consist of interest, amortization of deferred financing costs,
    amortization of debt discount and that portion of rental payments on
    operating leases deemed representative of the interest factor.

                                  RISK FACTORS
 
     In addition to the other information set forth and incorporated by
reference herein, Holders of Series A Notes should carefully consider the
following information in evaluating the Company and its business before deciding
to tender the Series A Notes in the Exchange Offer. The information contained
and incorporated by reference herein contains forward-looking statements that
involve a number of risks and uncertainties. A number of factors, including
those discussed below, could cause results to differ materially from those
anticipated by such forward-looking statements. In addition, such
forward-looking statements are necessarily dependent upon assumptions, estimates
and data that may be incorrect or imprecise. Accordingly, any forward-looking
statements included or incorporated by reference herein do not purport to be
predictions of future events or circumstances and may not be realized.
 
LEVERAGE
 
     The Company is highly leveraged. As of September 28, 1997, after giving pro
forma effect to the Transactions, the Company would have had total consolidated
indebtedness of approximately $112.9 million and a ratio of long-term debt to
total capitalization of approximately 94.8%. See "Capitalization" and "Unaudited
Pro Forma Financial Data." The Company may incur additional indebtedness in the
future, including through available borrowings under the Credit Facility,
subject to the satisfaction of certain financial tests. See "Description of
Other Indebtedness -- Credit Facility" and "Description of the Exchange Notes --
Certain Covenants -- Incurrence of Indebtedness and Issuance of Preferred
Stock."
 
     The degree to which the Company is leveraged could have important
consequences to the holders of the Exchange Notes, including the following: (i)
the Company's ability to obtain additional financing in the future for working
capital, capital expenditures, acquisitions or other purposes may be limited or
impaired; (ii) the Company's flexibility with respect to certain matters will be
limited by covenants contained in the Indenture and the Credit Facility which
will limit the ability of the Company and its subsidiaries to incur additional
indebtedness, grant liens, pay dividends, redeem capital stock, prepay certain
subordinated indebtedness and enter into mergers and other similar transactions;
and (iii) the Company's degree of leverage may make it more vulnerable to
economic downturns, limit its ability to pursue other business opportunities and
reduce its flexibility in responding to changing business and economic
conditions.
 
     The Company's ability to generate cash for the repayment of debt, including
the Exchange Notes, will be dependent upon the future performance of the
Company's business, which will in turn be subject to financial, competitive,
economic and other factors affecting the operations of the Company, including
certain factors beyond its control.
 
SUBORDINATION OF THE EXCHANGE NOTES
 
     The Exchange Notes will be unsecured obligations of the Issuers and will be
subordinated in right of payment to all current and future Senior Debt of the
Issuers, including all indebtedness of the Issuers under the Credit Facility. In
addition, the guarantees of the Exchange Notes will be subordinated to all
current and future Senior Debt of the Guarantors, including the Guarantors'
obligations under the Credit Facility. See "Description of the Exchange
Notes -- Subordination." As of September 28, 1997, after giving pro forma effect
to the Transactions, the Issuers would have had approximately $3.4 million of
Senior Debt outstanding, consisting of outstanding borrowings under the Credit
Facility. In addition, the Issuers would have had $41.6 million of additional
borrowings available under the Credit Facility. As a result of the subordination
provisions of the Indenture, in the event of a liquidation or insolvency
involving the Company, holders of the Exchange Notes may recover less ratably
than creditors of the Company who are holders of Senior Debt. The Indenture will
permit the Company to incur additional Senior Debt, subject to certain financial
tests. See "Description of the Exchange Notes -- Certain Covenants -- Incurrence
of Indebtedness and Issuance of Preferred Stock."
 
COMPETITION
 
     The facilities services industry is highly competitive. The Company
competes against large national and multi-national organizations, most of which
have greater financial and marketing resources than the Company.
 
                                       12
<PAGE>   18
 
In the various local marketplaces for core janitorial and custodial services,
barriers to entry are low, and the Company competes against numerous smaller
service providers, many of which may have more experience in and knowledge of
the local market for such services. In these same markets, the Company is also
increasingly facing large competitors that are willing to accept lower profit
margins in order to capture market share. There can be no assurance that
competition will not have an adverse effect on the Company's financial condition
or results of operations. See "Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is a service business that is highly dependent upon the
strength of its customer relationships. Accordingly, the Company's success
depends to a large extent upon the continued services of its key managers. In
particular, the Company is dependent upon the day-to-day leadership and
experience of Steven C. Kletjian, its Chairman, Chief Executive Officer and
principal shareholder. Mr. Kletjian is not subject to an employment agreement
with the Company or any of its subsidiaries. In addition, retention of other key
personnel is important to the continued success of the Company. The loss of
other key executive personnel could have a material adverse effect on the
Company. See "Management."
 
DEPENDENCE ON HOURLY WAGE AND UNION EMPLOYEES
 
     The Company's business depends upon its ability to continue to recruit,
train and retain large numbers of hourly wage employees. Competition for such
employees, particularly in areas with strong regional economies, has led to
increased hourly wage levels and employee turnover. Inability to recruit, train
and retain such employees at competitive wage rates could have a material
adverse effect on the Company. In addition, the Company's workforce is heavily
unionized. Approximately 44% of the Company's workforce is unionized under more
than 170 different union contracts. As these union contracts expire, the Company
may be required to renegotiate them in an environment of increasing wage rates.
In addition, there can be no assurance that the Company will be able to
renegotiate union contracts on terms favorable to the Company or without
experiencing a work stoppage. See "Business -- Employees."
 
LENGTH OF CONTRACTS
 
     The Company performs the majority of its work for customers under contracts
with a stated term of from one to three years, with termination clauses
permitting the customer to cancel the contract on 30 to 90 days' notice. While
the Company has maintained long-standing relationships with many of its
customers, and has experienced a low customer turnover rate, there can be no
assurance that the Company's customers will not exercise their rights to
terminate their contracts prior to expiration, or that the Company will be
successful in negotiating new contracts with customers as such contracts expire.
See "Business -- Contracts."
 
CONTROL BY PRINCIPAL SHAREHOLDERS
 
     All of the voting common shares of beneficial ownership in the Company are
privately-held by members of the Kletjian family. As a result, these persons are
in a position to elect the Company's Board of Trustees, and to control the
management, policies and operations of the Company. These persons do not owe
fiduciary duties to the holders of the Notes. See "Share Ownership."
 
POTENTIAL ENVIRONMENTAL LIABILITY
 
     The nature of the Company's business necessarily involves the transport,
storage, use and disposal of cleaning solvents, lubricants, chemicals and other
hazardous materials by Company employees to, on and around the customers'
facilities or, in certain cases, facilities leased by the Company on behalf of
its customers. Such activities are subject to stringent and changing federal,
state and local regulation, and present the potential for liability of the
Company for the actions of its employees in handling such materials. In
addition, the exposure of the Company's employees to these materials may give
rise to claims by employees against the Company. As a result, there can be no
assurance that compliance with governmental regulations or
 
                                       13
<PAGE>   19
 
liability related to hazardous materials will not have a material adverse effect
on the Company's financial condition or results of operations. See
"Business -- Facilities."
 
LIABILITY CLAIMS AND INSURANCE COVERAGE
 
     The nature of the Company's services exposes it to risks of liability for
employee acts (including negligence and harassment), injuries (including
workers' compensation claims) and omissions. The Company carries insurance of
various types, including workers' compensation, employment practices, vehicle
and general liability coverage. While the Company seeks to maintain appropriate
levels of insurance, there can be no assurance that the Company will avoid
material claims or adverse publicity related thereto. There can also be no
assurance that the Company's insurance will be adequate to cover the Company's
liabilities or that such insurance coverage will remain available at acceptable
costs. A successful claim brought against the Company for which coverage is
denied or which is in excess of its insurance coverage could have a material
adverse effect on the Company's financial condition or results of operations.
 
GOVERNMENTAL REGULATION
 
     Due to the nature of the Company's business, particularly in its Security
SBU, the Company's operations are subject to a variety of federal, state, county
and municipal laws, regulations and licensing requirements, including labor,
employment, immigration, health and safety and environmental regulations and
regulations affecting private security firms. Changes in such laws, regulations
and licensing requirements may constrain the Company's ability to provide
services to customers or increase the costs of such services. In addition,
competitive pricing conditions in the industry may constrain the Company's
ability to adjust its billing rates to reflect any such increased costs.
 
ACQUISITION RISKS
 
     As part of its strategy, the Company may pursue the acquisition of other
companies, assets or business lines that complement or expand its existing
business. Acquisitions involve a number of risks that could adversely affect the
Company, including the diversion of management's attention, the unsuccessful
integration of the operations and personnel of the acquired companies and the
potential loss of key employees or customers of the acquired operations. The
Company may not have had experience with the geographic or service markets of
the acquired business and accordingly may lack the management and marketing
expertise that will be necessary to successfully operate and integrate the
business. In addition, there can be no assurance that the Company will continue
to retain acquired management and other personnel, that the market will
favorably view the Company's entry into a new geographic or service market, or
that the Company will realize any of the other anticipated benefits of an
acquisition. No assurance can be given that future acquisitions by the Company
will not materially and adversely affect the Company or that any such future
acquisition will enhance the Company's business.
 
CHANGE OF CONTROL
 
     In the event of a Change of Control, the Issuers will be required to make
an offer to each holder of Exchange Notes to repurchase all or any part of such
holder's Exchange Notes at a repurchase price equal to 101% of the principal
amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the repurchase date. The source of funds for any such repurchase
would be the Company's available cash or cash generated from operating or other
sources, including borrowings, sales of equity or funds provided by a new
controlling person. However, there can be no assurance that sufficient funds
will be available at the time of any Change of Control to make any required
purchases of the Exchange Notes tendered. In addition, the Credit Facility may
prohibit the Company from making any such required repurchases. The failure of
the Company to offer to repurchase Exchange Notes, or to repurchase Exchange
Notes tendered, following a Change of Control will result in a default under the
Indenture, which could lead to a cross-default under the Credit Facility and
under the terms of other indebtedness of the Company. In such a case, the
subordination provisions of the Indenture may limit the ability of the holders
of the Exchange Notes to receive payment in respect of their Exchange Notes. See
"Description of Other Indebtedness -- Credit Facility," "Description of
 
                                       14
<PAGE>   20
 
the Exchange Notes -- Subordination" and "-- Repurchase of Exchange Notes at the
Option of Holders -- Change of Control."
 
RESTRICTIONS IMPOSED BY TERMS OF INDEBTEDNESS
 
     The Indenture governing the terms of the Exchange Notes contains certain
covenants limiting, subject to certain exceptions, the incurrence of additional
indebtedness, the payment of dividends, the redemption of capital stock, the
making of certain investments, the issuance of capital stock of subsidiaries,
the creation of liens and other restrictions affecting the Company's
subsidiaries, the issuance of guarantees, transactions with affiliates, asset
sales and certain mergers and consolidations. A breach of any of these covenants
could result in an event of default under the Indenture. In addition, the New
Credit Facility and the instruments governing the Company's other indebtedness
contain other more restrictive covenants and require the Company to satisfy
certain financial tests. The Company's ability to comply with such covenants and
breach of any of these covenants could result in an event of default under the
New Credit Facility. In the event of a default under the New Credit Facility,
the lenders thereunder could elect to declare all amounts borrowed, together
with accrued interest, to be immediately due and payable, and the lenders under
the New Credit Facility or the instruments governing the Company's other
indebtedness could constitute a cross-default under the Indenture and any
instruments governing the Company's other indebtedness, and a default under the
Indenture could constitute a cross-default under the New Credit Facility and any
instruments governing the Company's other indebtedness. In the event of a
default under the New Credit Facility or other Senior Debt of the Company, the
subordination provisions of the Indenture may restrict payments with respect to
the Exchange Notes. See "-- Subordination," "Description of the Exchange
Notes -- Certain Covenants" and "Description of Other Indebtedness."
 
ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES
 
     The Exchange Notes are being offered to the holders of the Series A Notes.
The Series A Notes were offered and sold in October 1997 (i) to "Qualified
Institutional Buyers" (as defined in Rule 144A under the Securities Act), (ii)
to other institutional "accredited investors" (as defined in Rule 501(a)(1),
(2), (3) or (7) under the Securities Act) and (iii) outside the United States in
reliance on Regulation S under the Securities Act and are eligible for trading
in the Private Offering, Resales and Trading through Automated Linkages
("PORTAL") market.
 
     The Exchange Notes will be a new class of securities for which there
currently is no established trading market. Although the Exchange Notes will
generally be permitted to be resold or otherwise transferred by nonaffiliates of
the Company without compliance with the registration requirements under the
Securities Act, the Company does not intend to apply for listing of the Exchange
Notes on any national securities exchange or for quotation of the Exchange Notes
on any automated dealer quotation system. Although the Initial Purchasers have
informed the Company that they currently intend to make a market in the Exchange
Notes, the Initial Purchasers are not obligated to do so, and any such
market-making may be discounted at any time without notice. The liquidity of any
market for the Exchange Notes will depend upon the number of holders of the
Exchange Notes, the interest of securities dealers in making a market in the
Exchange Notes and other factors. Accordingly, there can be no assurance as to
the development or liquidity of any market for the Exchange Notes. If an active
trading market for the Exchange Notes does not develop, the market price and
liquidity of the Exchange Notes may be adversely affected. If the Exchange Notes
are traded, they may trade at a discount from their initial offering price,
depending upon prevailing interest rates, the market for similar securities, the
performance of the Company and certain other factors. The liquidity of, and
trading markets for, the Exchange Notes may also be adversely affected by
general declines in the market for non-investment grade debt. Such declines may
adversely affect the liquidity of, and trading markets for, the Exchange Notes
independent of the financial performance of, or prospects for, the Company.
 
FRAUDULENT CONVEYANCE MATTERS
 
     Under applicable provisions of federal bankruptcy law and comparable
provisions of state and federal fraudulent conveyance laws, if it were found
that any Guarantor (a) had incurred the indebtedness
 
                                       15
<PAGE>   21
 
represented by its guarantee of the Exchange Notes with an intent to hinder,
delay or defraud creditors or (b) received less than reasonable equivalent value
or fair consideration for incurring such indebtedness and (i) was insolvent or
was rendered insolvent by reason of such incurrence, (ii) was engaged or about
to engage in a business or transaction for which its remaining assets
constituted unreasonably small capital to carry on its business or (iii)
intended to incur, or believed that it would incur, debts beyond its ability to
pay such debts as they matured, the obligations of such Guarantor under its
guarantee of the Exchange Notes could be avoided or claims in respect of such
guarantee could be subordinated to all other debts of such Guarantor. A legal
challenge of a guarantee of the Exchange Notes could, among other things, focus
on the benefits, if any, realized by a Guarantor as a result of the issuance by
the Issuers of the Exchange Notes. To the extent that a Guarantor's guarantee of
the Exchange Notes were held to be unenforceable as a fraudulent conveyance for
any reason, the holders of the Exchange Notes would cease to have any direct
claim in respect of such Guarantor. In the event a Guarantor's guarantee of the
Exchange Notes were held to be subordinated, the claims of the holders of the
Exchange Notes could be subordinated to claims of other creditors of such
Guarantor, including holders of Senior Debt and other holders of subordinated
indebtedness of such Guarantor.
 
     The measure of insolvency for purposes of determining whether a transfer is
avoidable as a fraudulent conveyance varies depending upon the law of the
jurisdiction which is being applied. Generally, however, a debtor would be
considered insolvent if the sum of all its liabilities, including contingent
liabilities, were greater than the fair saleable value of its assets at a fair
valuation, or if the present fair saleable value of the debtor's assets were
less than the amount required to repay its liabilities on its existing debts,
including contingent liabilities, as they become absolute and matured. There can
be no assurance as to what standard a court would apply in order to make such
determination.
 
     Each of the Guarantors believes that it will receive equivalent value at
the time the indebtedness under the Exchange Notes and the guarantees is
incurred. In addition, none of the Guarantors believes that, after giving effect
to the Exchange Offer, it (i) was or will be insolvent or rendered insolvent,
(ii) was or will be engaged in a business or transaction for which its remaining
assets constitute unreasonably small capital or (iii) intends or intended to
incur, or believes or believed that it will or would incur, debts beyond its
ability to pay such debts as they mature. Since, however, the question of
whether a guarantee is a fraudulent conveyance is inherently fact-based and
fact-specific, there can be no assurance that a court passing on such questions
would agree with the Guarantors.
 
RESTRICTIONS ON TRANSFER
 
     The Series A Notes were offered and sold by the Company in a private
offering exempt from registration pursuant to the Securities Act and have been
resold pursuant to Rule 144A, Rule 501(a)(1), (2), (3) or (7) and Regulation S
and other exemptions under the Securities Act. As a result, the Series A Notes
may not be reoffered or resold by purchasers except pursuant to an effective
registration statement under the Securities Act or pursuant to an applicable
exemption from such registration, and the Series A Notes are legended to
restrict transfer as aforesaid. Each Holder (other than any Holder who is an
affiliate or promoter of the Company) who duly exchanges Series A Notes for
Exchange Notes in the Exchange Offer will receive Exchange Notes that are freely
transferable under the Securities Act. Holders who participate in the Exchange
Offer should be aware, however, that if they accept the Exchange Offer for the
purpose of engaging in a distribution, the Exchange Notes may not be publicly
reoffered or resold without complying with the registration and prospectus
delivery requirements of the Securities Act. As a result, each Holder accepting
the Exchange Offer will be deemed to have represented, by its acceptance of the
Exchange Offer, that it acquired the Exchange Notes in the ordinary course of
business and that it is not engaged in, and does not intend to engage in, a
distribution of the Exchange Notes. If existing Commission interpretations
permitting free transferability of the Exchange Notes following the Exchange
Offer are changed prior to consummation of the Exchange Offer, the Company will
use its best efforts to register the Series A Notes for resale under the
Securities Act. See "Prospectus Summary -- The Exchange Offer" and "Description
of the Exchange Notes -- Registration Rights; Liquidated Damages."
 
                                       16
<PAGE>   22
 
     The Series A Notes currently may be sold pursuant to the restrictions set
forth in Rule 144A, Rule 501(a)(1), (2), (3) or (7) or Regulation S under the
Securities Act or pursuant to another available exemption under the Securities
Act without registration under the Securities Act. To the extent that Series A
Notes are tendered and accepted in the Exchange Offer, the trading market for
the untendered and tendered but unaccepted Series A Notes could be adversely
affected.
 
EXCHANGE OFFER PROCEDURES
 
     Issuance of the Exchange Notes for Series A Notes pursuant to the Exchange
Offer will be made only after timely receipt by the Exchange Agent of such
Series A Notes, a properly completed, duly executed Letter of Transmittal and
all other required documents. Therefore, Holders desiring to tender their Series
A Notes in exchange for Exchange Notes should allow for sufficient time to
ensure timely delivery. The Company is under no duty to give notification of
defects or irregularities with respect to the tenders of Series A Notes for
exchange. Any Series A Notes that are not tendered or are tendered but not
accepted will, following the consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof and, upon
consummation of the Exchange Offer, the registration rights under the
Registration Rights Agreement generally will terminate. In addition, any Holder
who tenders pursuant to the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes may be deemed to have received restricted
securities and, if so, will be required to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale. Each broker-dealer that receives Exchange Notes for its own account in
exchange for Series A Notes, where such Series A Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "The Exchange Offer."

                                  THE COMPANY
 
     UNICCO was founded as a Massachusetts corporation in 1949, and was
reorganized as a Massachusetts business trust in 1988. UNICCO is a subchapter S
company for federal income tax purposes. The Company's principal executive
offices are located at Four Copley Place, Boston, Massachusetts 02116, and its
telephone number is (617) 859-9100. UNICCO Finance, which is a co-obligor under
the Notes, is a Delaware corporation and a wholly-owned subsidiary of UNICCO.
 
     Prior to the Offering, the operations of the Company were conducted through
UNICCO and its subsidiary, and through affiliated entities owned by the same
shareholders as UNICCO. Effective January 1, 1997, such affiliated entities
elected to be taxed as subchapter S corporations for federal income tax
purposes. In connection with the Offering, the shareholders of UNICCO
contributed their interests in such affiliated entities to UNICCO (the
"Refinancing"), as a result of which all of the operations of the Company will
be conducted through UNICCO and its subsidiaries. See "Certain Transactions."
The Combined Consolidated Financial Statements of the Company and the other
historical financial and statistical data included in this Offering Memorandum
include the combined results of operations of UNICCO, its subsidiaries and such
affiliated entities.
 
                               THE EXCHANGE OFFER
 
     The following discussion sets forth or summarizes what the Company believes
are the material terms of the Exchange Offer, including those set forth in the
Letter of Transmittal distributed with this Prospectus. This summary is
qualified in its entirety by reference to the full text of the documents
underlying the Exchange Offer, copies of which are filed as exhibits to the
Registration Statement of which this Prospectus is a part, and are incorporated
by reference herein.
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     In connection with the sale of the Series A Notes pursuant to the Purchase
Agreement, dated October 14, 1997 (the "Purchase Agreement"), between the
Company and the Initial Purchasers, the Initial Purchasers became entitled to
the benefits of the Registration Rights Agreement, dated as of October 17, 1997,
between the Company and the Initial Purchasers (the "Registration Rights
Agreement").
 
     Under the Registration Rights Agreement, the Company agreed to (a) file a
registration statement in connection with a registered exchange offer within 45
days after October 17, 1997, the date the Series A Notes were issued (the "Issue
Date"), (b) use best efforts to cause such registration statement to become
effective under the Securities Act within 120 days of the Issue Date, (c) use
best efforts to keep such registration statement effective until the closing of
the Exchange Offer and (d) use best efforts to cause such registered Exchange
Offer to be consummated within 30 days after the effective date of such
registration statement. Within the applicable time periods, the Company will
endeavor to register under the Securities Act all of the Exchange Notes pursuant
to a registration statement under which the Company will offer each Holder of
Series A Notes the opportunity to exchange any and all of the outstanding Series
A Notes held by such Holder for Exchange Notes in an aggregate principal amount
equal to the aggregate principal amount of Series A Notes tendered for exchange
by such Holder. Subject to limited exceptions, the Exchange Offer being made
hereby, if commenced and consummated within such applicable time periods, will
satisfy those requirements under the Registration Rights Agreement. In such
event, the Series A Notes would remain outstanding and would continue to accrue
interest, but would not retain any rights under the Registration Rights
Agreement. Holders of Series A Notes seeking liquidity in their investment would
have to rely on exemptions to registration requirements under the securities
laws, including the Securities Act. A copy of the Registration Rights Agreement
has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The term "Holder" with respect to the Exchange Offer means
any person in whose name the Series A Notes are registered on the books of the
Company or any other person who has obtained a properly completed bond power
from the registered holder.
 
                                       18
<PAGE>   24
 
     Because the Exchange Offer is for any and all Series A Notes, the principal
amount of Series A Notes tendered and exchanged in the Exchange Offer will
reduce the principal amount of Series A Notes outstanding. Following the
consummation of the Exchange Offer, Holders who did not tender their Series A
Notes generally will not have any further registration rights under the
Registration Rights Agreement, and such Series A Notes will continue to be
subject to certain restrictions on transfer. Accordingly, the liquidity of the
market for such Series A Notes could be adversely affected. The Series A Notes
are currently eligible for sale pursuant to Rule 144A, Rule 501(a)(1), (2), (3)
or (7) or Regulation S through the PORTAL Market. Because the Company
anticipates that most Holders of Series A Notes will elect to exchange such
Series A Notes for Exchange Notes due to the absence of restrictions on the
resale of Exchange Notes under the Securities Act, the Company anticipates that
the liquidity of the market for any Series A Notes remaining after the
consummation of the Exchange Offer may be substantially limited. See
"Description of the Exchange Notes -- Registration Rights; Liquidated Damages"
and "Risk Factors -- Absence of Public Market for the Exchange Notes."
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and conditions set forth in this Prospectus and in the
accompanying Letter of Transmittal, the Company will accept all Series A Notes
properly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the Expiration Date. The Company will issue $1,000 principal amount of Exchange
Notes in exchange for each $1,000 principal amount of outstanding Series A Notes
accepted in the Exchange Offer. Holders may tender some or all of their Series A
Notes pursuant to the Exchange Offer.
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Series A Notes except that (i) the Exchange Notes have been registered
under the Securities Act and hence will not bear legends restricting the
transfer thereof, and (ii) the holders of Exchange Notes generally will not be
entitled to certain rights under the Registration Rights Agreement, which rights
generally will terminate upon consummation of the Exchange Offer. The Exchange
Notes will evidence the same debt as the Series A Notes and will be entitled to
the benefits of the Indenture.
 
     Holders of Series A Notes do not have any appraisal or dissenters' rights
in connection with the Exchange Offer.
 
     The Company shall be deemed to have accepted validly tendered Series A
Notes when, as and if the Company has given oral or written notice thereof to
the Exchange Agent. The Exchange Agent will act as agent for the tendering
Holders of Series A Notes for the purpose of receiving the Exchange Notes from
the Company and delivering Exchange Notes to such Holders.
 
     If any tendered Series A Notes are not accepted for exchange because of an
invalid tender or the occurrence of certain other events set forth herein,
certificate for any such unaccepted Series A Notes will be returned, without
expense, to the tendering Holder thereof as promptly as practicable after the
Expiration Date.
 
     Holders of Series A Notes who tender pursuant to the Exchange Offer will
not be required to pay brokerage commissions or fees or, subject to the
instructions in the Transmittal Letter, transfer taxes with respect to the
exchange of Series A Notes pursuant to the Exchange Offer. The Company will pay
all charges and expenses, other than certain applicable taxes, in connection
with the Exchange Offer. See "-- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The Exchange Offer shall remain open for acceptance for a period of not
less than 20 business days (the "Exchange Period"). The Expiration Date will be
5:00 p.m., New York City time, on               , 1998, unless the Company, in
its sole discretion, extends the Exchange Offer, in which case the Expiration
Date will be the latest business day to which the Exchange Offer is extended.
 
     In order to extend the Expiration Date, the Issuers will notify the
Exchange Agent of any extension by oral or written notice and will mail to the
record Holders an announcement thereof, each prior to 9:00 a.m.,
 
                                       19
<PAGE>   25
 
New York City time, on the next business day after the previously scheduled
Expiration Date. Such announcement may state that the Company is extending the
Exchange Offer for a specified period of time.
 
     The Company reserves the right (i) to delay accepting any Series A Notes,
to extend the Exchange Offer or to terminate the Exchange Offer and not accept
Series A Notes not previously accepted if any of the conditions set forth under
"-- Conditions" shall have occurred and shall not have been waived by the
Company, by giving oral or written notice of such delay, extension or
termination to the Exchange Agent, or (ii) to amend the terms of the Exchange
Offer in any manner. Any such delay in acceptance, extension, termination or
amendment will be followed as promptly as practicable by oral or written notice
thereof. If the Exchange Offer is amended in a manner determined by the Issuers
to constitute a material change, the Issuers will promptly disclose such
amendment in a manner reasonably calculated to inform the Holders of such
amendment, and the Issuers will extend the Exchange Offer for a period of five
to ten business days, depending upon the significance of the amendment and the
manner of disclosure to Holders, if the Exchange offer would otherwise expire
during such five to ten business day period.
 
     Without limiting the manner in which the Issuers may choose to make public
announcement of any extension, amendment or termination of the Exchange Offer,
the Issuers shall have no obligation to publish, advertise or otherwise
communicate any such public announcement, other than by making a timely release
to the Dow Jones News Service or other comparable service.
 
INTEREST ON THE EXCHANGE NOTES
 
     Interest on the Exchange Notes is payable semi-annually on April 15 and
October 15 of each year at the rate of 9 7/8% per annum. The Exchange Notes will
bear interest from October 17, 1997, the date of issuance of the Series A Notes,
or the most recent interest payment date to which interest on such Series A
Notes has been paid, whichever is later. Accordingly, Holders of Series A Notes
that are accepted for exchange will not receive interest that is accrued but
unpaid on the Series A Notes at the time of tender, but such interest will be
payable in respect of the Exchange Notes delivered in exchange for such Series A
Notes on the first interest payment date after the Expiration Date.
 
PROCEDURES FOR TENDERING
 
     Only a Holder of Series A Notes may tender such Series A Notes pursuant to
the Exchange Offer. To tender pursuant to the Exchange Offer, a Holder must
complete, sign and date the Letter of Transmittal, or a facsimile thereof, have
the signatures thereon guaranteed if required by instruction 4 of the Letter of
Transmittal, and mail or otherwise deliver such Letter of Transmittal or such
facsimile, together with the Series A Notes and any other required documents, to
the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration
Date. Delivery of the Series A Notes may be made by book-entry transfer in
accordance with the procedures described below. Confirmation of such book-entry
transfer must be received by the Exchange Agent prior to the Expiration Date.
 
     The tender by a Holder of Series A Notes and the acceptance thereof by the
Company will constitute an agreement between such Holder and the Company in
accordance with the terms and subject to the conditions set forth herein in the
Letter of Transmittal.
 
     THE METHOD OF DELIVERY OF SERIES A NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION
DATE. NO LETTER OF TRANSMITTAL OR SERIES A NOTES SHOULD BE SENT TO THE COMPANY.
HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES TO EFFECT SUCH TENDER FOR SUCH HOLDERS.
 
                                       20
<PAGE>   26
 
     Any beneficial Holder whose Series A Notes are registered in the name of
such Holder's broker, dealer, commercial bank, trust company or other nominee
and who wishes to tender should contact such registered holder promptly and
instruct such registered holder to tender on his behalf. If such beneficial
Holder wishes to tender on such beneficial Holder's behalf, such beneficial
Holder must, prior to completing and executing the Letter of Transmittal and
delivering his Series A Notes, either make appropriate arrangements to register
ownership of the Series A Notes in such Holder's name or obtain a properly
completed bond power from the registered holder. The transfer of record
ownership may take considerable time.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.
or a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution") unless the Series A
Notes tendered pursuant thereto are tendered (i) by a registered Holder who has
not completed the box entitled "Special Registration Instructions" or "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution. In the event that signatures on a Letter of Transmittal
or a notice of withdrawal, as the case may be, are required to be guaranteed,
such guarantees must be by an Eligible Institution.
 
     If the Letter of Transmittal is signed by a person other than the
registered Holder of any Series A Notes listed therein, such Series A Notes must
be endorsed or accompanied by appropriate bond powers and a proxy which
authorizes such person to tender the Series A Notes on behalf of the registered
Holder, in each case signed as the name of the registered Holder or Holders
appears on the Series A Notes with the signature thereon guaranteed by an
Eligible Institution.
 
     If the Letter of Transmittal or any Series A Notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect to
the Series A Notes at the DTC for the purpose of facilitating the Exchange
Offer, and subject to the establishment thereof, any financial institution that
is a participant in the DTC may make book-entry delivery of the Series A Notes
by causing the DTC to transfer such Series A Notes into the Exchange Agent's
account with respect to the Series A Notes in accordance with the DTC's
procedures for such transfer. Although delivery of the Series A Notes may be
effected through book-entry transfer into the Exchange Agent's account at the
DTC, a Letter of Transmittal properly completed and duly executed with any
required signature guarantee and all other required documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures. Delivery of documents to the DTC does not
constitute delivery to the Exchange Agent.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Series A Notes and withdrawal of the tendered
Series A Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute right
to reject any and all Series A Notes not properly tendered or any Series A Notes
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the right to waive any
irregularities or conditions of tender as to particular Series A Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including, the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Series A Notes must be cured within such time as the
Company shall determine. Neither the Company, the Exchange Agent nor any other
person shall be under any duty to give notification of defects or irregularities
with respect to tenders of Series A Notes, nor shall any of them incur any
liability for failure to give such notification. Tenders of Series A Notes will
not be deemed to have been made until such irregularities have
 
                                       21
<PAGE>   27
 
been cured or waived. Any Series A Notes received by the Exchange Agent that are
not properly tendered and as to which the defects or irregularities have not
been cured or waived will be returned without cost to such Holder by the
Exchange Agent to the tendering Holders of Series A Notes, unless otherwise
provided in the Letter of Transmittal, as soon as practicable following the
Expiration Date.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Series A Notes and (i) whose Series A
Notes are not immediately available, or (ii) who cannot deliver their Series A
Notes, the Letter of Transmittal or any other required documents to the Exchange
Agent (or comply with the procedures for book-entry transfer) prior to the
Expiration Date, may effect a tender if:
 
          a. the tender is made through an Eligible Institution;
 
          b. prior to the Expiration Date, the Exchange Agent receives from such
     Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
     setting forth the name and address of the Holder of the Series A Notes, the
     certificate or registration number or numbers of such Series A Notes and
     the principal amount of Series A Notes tendered, stating that the tender is
     being made thereby, and guaranteeing that, within five business days after
     the Expiration Date, the Letter of Transmittal (or facsimile thereof)
     together with the certificates(s) representing the Series A Notes to be
     tendered in proper form for transfer (or a confirmation of book-entry
     transfer of such Series A Notes into the Exchange Agent's account at the
     Depository) and any other documents required by the Letter of Transmittal
     will be deposited by the Eligible Institution with the Exchange Agent; and
 
          c. such properly completed and executed Letter of Transmittal (or
     facsimile thereof), together with the certificate(s) representing all
     tendered Series A Notes in proper form for transfer (or a confirmation of
     book-entry transfer of such Series A Notes into the Exchange Agent's
     account at the Depository) and all other documents required by the Letter
     of Transmittal are received by the Exchange Agent within five business days
     after the Expiration Date.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Series A Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
     To withdraw a tender of Series A Notes pursuant to the Exchange Offer, a
written or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at the address set forth herein prior to 5:00 p.m., New York City
time, on the Expiration Date. Any such notice of withdrawal must (i) specify the
name of the person having deposited the Series A Notes to be withdrawn (the
"Depositor"), (ii) identify the Series A Notes to be withdrawn (including the
certificate or registration number(s) and principal amount of such Series A
Notes, or, in the case of notes transferred by book-entry transfer, the name and
number of the account at the DTC to be credited), (iii) be signed by the
Depositor in the same manner as the original signature on the Letter of
Transmittal by which such Series A Notes were tendered (including any required
signature guarantees) or be accompanied by documents of transfer sufficient to
have the Trustee (as defined herein) with respect to the Series A Notes register
the transfer of such Series A Notes into the name of the Depositor withdrawing
the tender, (iv) specify the name in which any such Series A Notes are to be
registered, if different from that of the Depositor and (v) include a statement
that such Holder is withdrawing such Holder's election to have such Series A
Notes exchanged. All questions as to the validity, form and eligibility
(including time of receipt) of such withdrawal notices will be determined by the
Company, whose determination shall be final and binding on all parties. Any
Series A Notes withdrawn will be deemed not to have been validly tendered for
purposes of the Exchange Offer, and no Exchange Notes will be issued with
respect thereto unless the Series A Notes so withdrawn are validly retendered.
Any Series A Notes which have been tendered but which are not accepted for
payment will be returned to the Holder thereof without cost to such Holder as
soon as practicable after withdrawal, rejection of tender or termination of the
Exchange
 
                                       22
<PAGE>   28
 
Offer. Properly withdrawn Series A Notes may be retendered by following one of
the procedures described under "-- Procedures for Tendering" at any time prior
to the Expiration Date.
 
CONDITIONS
 
     Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or to exchange Exchange Notes for, any
Series A Notes, and may terminate or amend the Exchange Offer as provided herein
before the acceptance of such Series A Notes, if:
 
          (i) any law, statute, rule, regulation or interpretation by the staff
     of the Commission is proposed, adopted or enacted, which, in the reasonable
     judgment of the Company, might materially impair the ability of the Company
     to proceed with the Exchange Offer or materially impair the contemplated
     benefits of the Exchange Offer to the Company; or
 
          (ii) any governmental approval has not been obtained, which approval
     the Company shall, in its reasonable judgment, deem necessary for the
     consummation of the Exchange Offer as contemplated hereby.
 
     If the Company determines in its reasonable judgment that any of the
conditions are not satisfied, the Company may (i) refuse to accept any Series A
Notes and return all tendered Series A Notes to the tendering Holders, (ii)
extend the Exchange Offer and retain all Series A Notes tendered prior to the
expiration of the Exchange Offer subject, however, to the rights of Holders to
withdraw such Series A Notes (see "-- Withdrawal of Tenders") or (iii) waive
such unsatisfied conditions with respect to the Exchange Offer and accept all
properly tendered Series A Notes which have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered Holders, and, depending upon the significance of
the waiver and the manner of disclosure to the registered Holders, the Company
will extend the Exchange Offer for a period of five to ten business days if the
Exchange Offer would otherwise expire during such five to ten business-day
period.

FEES AND EXPENSES
 
     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation for tenders pursuant to the
Exchange Offer is being made by mail; however, additional solicitations may be
made by telegraph, telephone or in person by officers and regular employees of
the Company and its affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or other
persons soliciting acceptances of the Exchange Offer. The Company, however, will
pay the Exchange Agent reasonable and customary fees for its services and will
reimburse the Exchange Agent for its reasonable out-of-pocket expenses in
connection therewith and pay
 
                                       23
<PAGE>   29
 
other registration expenses, including fees and expenses of the Trustee, filing
fees, blue sky fees and printing and distribution expenses.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Series A Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes or Series A Notes for principal amounts not tendered
or accepted for exchange are to be delivered to, or are to be registered or
issued in the name of any person other than the person signing the Letter of
Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Series A Notes pursuant to the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
person) will be payable by the tendering Holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering Holder.
 
ACCOUNTING TREATMENT
 
     The Exchange Notes will be recorded at the same carrying value as the
Series A Notes, which is the aggregate principal amount of the Series A Notes,
as reflected in the Company's accounting records on the date of exchange.
Accordingly, no gain or loss for accounting purposes will be recognized in
connection with the Exchange Offer. The cost of the Exchange Offer will be
deferred and amortized over the term of the Exchange Notes.
 
RESALE OF THE EXCHANGE NOTES
 
     Under existing Commission interpretations, the Exchange Notes would, in
general, be freely transferable after the Exchange Offer by any holder of such
Exchange Notes (other than any such holder which is an "affiliate" of the
Company within the meaning of Rule 405 of the Securities Act) without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that such Exchange Notes acquired pursuant to the Exchange Offer are
obtained in the ordinary course of such holder's business, and such holder does
not intend to participate, and has no arrangement or understanding to
participate, in the distribution of such Exchange Notes. Any holder who tenders
pursuant to the Exchange Offer with the intention to participate, or for the
purpose of participating, in a distribution of the Exchange Notes may not rely
on the position of the staff of the Commission enunciated in Exxon Capital
Holdings Corporation (available May 13, 1988) or Morgan Stanley & Co.,
Incorporated (available June 5, 1991) or similar interpretive letters, but
rather must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with a secondary resale transaction. In
addition, any such resale transaction should be covered by an effective
registration statement containing the selling security holders information
required by Item 507 of Regulation S-K of the Securities Act.
 
     Each broker-dealer that received Exchange Notes for its own account in
exchange for Series A Notes, where such Series A Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, may be a statutory underwriter and must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. The
Company has agreed to make available a prospectus meeting the requirements of
the Securities Act to any such broker-dealer for use in connection with any
resale of any Exchange Notes acquired in the Exchange Offer. A broker-dealer
which delivers such a prospectus to purchasers in connection with such resales
will be subject to certain of the civil liability provisions under the
Securities Act and will be bound by the provisions of the Registration Rights
Agreement (including certain indemnification rights and obligations).
 
     By tendering pursuant to the Exchange Offer, each Holder will represent to
the Company, among other things, that (i) the Exchange Notes acquired pursuant
to the Exchange Offer are being obtained in the ordinary course of its business,
(ii) neither the holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of the Exchange
Notes, and (iii) the holder and any such other person acknowledge that if they
participate in the Exchange Offer for the purpose of distributing the Exchange
Notes (a) they must, in the absence of an exemption therefrom, comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale of the
 
                                       24
<PAGE>   30
 
Exchange Notes and cannot rely on the no-action letters referenced above and (b)
failure to comply with such requirements in such instance could result in such
holder incurring liability under the Securities Act for which such holder is not
indemnified by the Company. Further, by tendering in the Exchange Offer, each
holder that may be deemed an "affiliate" (as defined in Rule 405 of the
Securities Act) of the Company will represent to the Company that such holder
understands and acknowledges that the Exchange Notes may not be offered for
resale, resold or otherwise transferred by that Holder without registration
under the Securities Act or an exemption therefrom.
 
     As set forth above, affiliates of the Company are not entitled to rely on
the foregoing interpretations of the staff of the Commission with respect to
resales of the Exchange Notes without compliance with the registration and
prospectus delivery requirements of the Securities Act.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     As a result of the making of this Exchange Offer, the Company will have
fulfilled one of its obligations under the Registration Rights Agreement, and
Holders of Series A Notes who do not tender their Series A Notes generally will
not have any further registration rights under the Registration Rights Agreement
or otherwise. Accordingly, any Holder that does not exchange such Holder's
Series A Notes for Exchange Notes will continue to hold the untendered Series A
Notes and will be entitled to all the rights and limitations applicable thereto
under the Indenture, except to the extent that such rights or limitations, by
their terms, terminate or cease to have further effectiveness as a result of the
Exchange Offer.
 
     The Series A Notes that are not exchanged for Exchange Notes pursuant to
the Exchange Offer will remain restricted securities. Accordingly, such Series A
Notes may be resold only (i) to the Company (upon redemption thereof or
otherwise), (ii) pursuant to an effective registration statement under the
Securities Act, (iii) so long as the 144A Notes are eligible for resale pursuant
to Rule 144A under the Securities Act, to a Qualified Institutional Buyer in a
transaction meeting the requirements of Rule 144A, (iv) outside the United
States to a foreign person pursuant to the exemption from the registration
requirements of the Securities Act provided by Regulation S thereunder, (v)
pursuant to an exemption from registration under the Securities Act provided by
Rule 144 thereunder (if available) or Regulation D, Rule 501 (a)(1), (2), (3) or
(7) or (vi) to an Accredited Investor in a transaction exempt from the
registration requirements of the Securities Act, in each case in accordance with
any applicable securities laws of any state of the United States or other
applicable jurisdiction. See "Risk Factors -- Restrictions on Transfer."
 
OTHER
 
     Participation in the Exchange Offer is voluntary, and Holders should
carefully consider whether to accept. Holders are urged to consult their
financial and tax advisors in making their own decision on what action to take.
 
     The Company may in the future seek to acquire untendered Series A Notes, to
the extent permitted by applicable law, in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise. The Company has
no present plans to acquire any Series A Notes that are not tendered in the
Exchange Offer or to file a registration statement to permit resales of any
untendered Series A Notes.
 
     In any state where the Exchange Offer does not fall under a statutory
exemption to the blue sky rules, the Company has filed the appropriate
registrations and notices, and has made the appropriate requests, to permit the
Exchange Offer to be made in such state.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OFFER
 
     The following discussion is based upon current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), existing and proposed Treasury
Department regulations (the "Regulations") and existing administrative
interpretations and court decisions. There can be no assurance that the Internal
Revenue Service (the "IRS") will not take a contrary view, and no ruling from
the IRS has been or will be sought. Legislative, judicial or administrative
changes or interpretations may be forthcoming that could alter
 
                                       25
<PAGE>   31
 
or modify the statements and conditions set forth herein. Any such changes or
interpretations may or may not be retroactive and could affect the tax
consequences to Holders. Certain Holders of the Series A Notes (including
insurance companies, tax-exempt organizations, financial institutions,
broker-dealers, foreign corporations and persons who are not citizens or
residents of the United States) may be subject to special rules not discussed
below. Each Holder of Series A Notes should consult his, her or its own tax
advisor as to the particular tax consequences of exchanging such Holder's Series
A Notes for Exchange Notes, including the applicability and effect of any state,
local or foreign tax laws.
 
     The issuance of the Exchange Notes to Holders of the Series A Notes
pursuant to the terms set forth in this Prospectus will not constitute an
exchange for United States federal income tax purposes because such exchange
does not represent a significant modification of the debt instruments.
Consequently, no gain or loss would be recognized by Holders of the Series A
Notes upon receipt of the Exchange Notes, and ownership of the Exchange Notes
will be considered a continuation of ownership of the Series A Notes. For
purposes of determining gain or loss upon the subsequent sale or exchange of the
Exchange Notes, a Holder's basis in the Exchange Notes should be the same as
such Holder's basis in the Series A Notes exchanged therefore. A Holder's
holding period for the Exchange Notes should include the Holder's holding period
for the Series A Notes exchanged therefor. The issue price, original issue
discount inclusion and other tax characteristics of the Exchange Notes should be
identical to the issue price, original issue discount inclusion and other tax
characteristics of the Series A Notes exchanged therefor.
 
     See also "Certain United States Federal Tax Considerations for Non-United
States Holders."

<PAGE>   32
 
                                USE OF PROCEEDS
 
     There will be no proceeds to the Company from the exchange of Series A
Notes pursuant to the Exchange Offer. The net proceeds from the Offering of
Series A Notes were approximately $100.6 million, after deducting discounts to
the Initial Purchaser and estimated offering expenses payable by the Company.
The net proceeds from the Offering, together with borrowings under the Credit
Facility, were used to repay indebtedness under the Company's existing credit
facility and certain other indebtedness of the Company, as set forth in the
table below (assuming consummation of the Offering on September 28, 1997). The
Offering, the initial borrowings under the Credit Facility, the application of
the proceeds therefrom as set forth below and the subchapter S election of the
affiliated entities that will be subsidiaries of the Company following the
Refinancing are collectively referred to herein as the "Transactions."

(1) Fiscal 1996 was a 53-week year. As a result, the Company's results of
    operations for fiscal 1996 include approximately $1.0 million of payroll and
    payroll-related expenses attributable to the additional week of operations
    that were not billed in the period to customers with fixed price contracts.
    See "Management's Discussion and Analysis of Financial Condition and Results
    of Operations."
 
(2) For the years ended June 25, 1995 and June 30, 1996, the Company was not
    subject to federal and certain state income taxes as it had elected to be
    treated as a subchapter S corporation. For the year ended June 29, 1997,
    certain entities of the Company were taxed as C corporations through
    December 31, 1996, at which time they elected to be treated as subchapter S
    corporations. See Note 7 of Notes to the Company's Combined Consolidated
    Financial Statements.
 
(3) EBITDA is defined as earnings before provision for income taxes, interest
    expense, interest income and depreciation and amortization. EBITDA is
    presented because it is a widely accepted financial indicator of a leveraged
    company's ability to service and/or incur indebtedness and because
    management believes that EBITDA is a relevant measure of the Company's
    ability to generate cash without regard to the Company's capital structure
    or working capital needs. 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.
 
(4) EBITDA margin represents EBITDA as a percentage of revenues.
 
(5) For purposes of calculating the ratio of earnings to fixed charges, earnings
    consist of income before provision for income taxes, plus fixed charges.
    Fixed charges consist of interest, amortization of deferred financing costs,
    amortization of debt discount and that portion of rental payments on
    operating leases deemed representative of the interest factor.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The matters discussed below and elsewhere herein contain forward-looking
statements regarding the future performance of the Company and other anticipated
future events. These matters involve risks and uncertainties that could cause
actual results to differ materially from the statements contained herein. In
addition to the matters discussed below, see "Risk Factors" for information
relating to such risks and uncertainties.
 
GENERAL
 
     The Company is a leading provider of integrated facilities services to a
broad base of industrial, commercial and institutional clients throughout the
United States and Canada. Services offered by the Company include industrial and
mechanical engineering, plant operations, custodial and maintenance services,
security services and administrative services.
 
     The Company recently organized its operations around four Strategic
Business Units. The fiscal 1997 revenues for each SBU are as follows:
Commercial: $214 million; Industrial: $149 million;
Education/Healthcare/Government: $110 million; and Security: $61 million.
 
     The Company structures its service contracts under three principal methods:
fixed price, cost plus fixed fee and hourly billing. These types of contracts
currently account for approximately 25%, 63% and 12%, respectively, of the
Company's revenues. Cost of service revenues primarily consists of direct labor
costs and related benefits, insurance, supplies and equipment. In fiscal 1997,
81.7% of the cost of service revenues consisted of direct labor costs and
related benefits. Selling, general and administrative expenses include employee
compensation and benefits, travel, insurance, rent, recruiting and training,
professional fees and bad debt expense. In fiscal 1997, 52.5% of selling,
general and administrative expenses consisted of employee compensation and
benefits.
 
     The Company's fiscal 1997 results of operations were significantly impacted
by the Ogden Acquisition on June 28, 1996. See "Business -- History of the
Company; the Ogden Acquisition." The Company accounted for this transaction
under the purchase method of accounting. A significant portion of the purchase
price of $62 million was allocated to intangible assets. Accordingly, the
Company has incurred significant amortization expenses in fiscal 1997. Interest
expense also increased significantly due to the indebtedness incurred to finance
the acquisition. In addition, operating profit margins were negatively impacted
by the Ogden Acquisition because Ogden's business consisted of more lower margin
contracts than the Company's.

COMPARISON OF THREE MONTH PERIODS ENDED SEPTEMBER 28, 1997 AND SEPTEMBER 29,
1996.
 
     Revenues.  Revenues for the first quarter of fiscal 1998 were $134.7
million compared to $128.3 million for the first quarter of fiscal 1997, an
increase of $6.4 million or 5.0%. This increase is primarily attributable to
revenue increases in the Company's Commercial SBU of $5.9 million. This increase
resulted from services performed under new contracts and the impact of a full
year's revenue from contracts acquired in the prior year. Revenues in the
Company's Canadian Division increased by $1.6 million between the comparable
quarters, primarily as a result of a new contract which commenced in the last
quarter of fiscal 1997. This increase was partially offset by a revenue decrease
of $1.0 million in the Company's Security SBU, primarily resulting from revenues
associated with non-recurring services performed for a customer in the first
quarter of fiscal 1997. Revenues attributable to this customer decreased
$524,000 between the comparable quarterly periods.
 
     Cost of Revenues.  Cost of revenues for the first quarter of fiscal 1998
were $121.1 million, or 89.9% of revenues, compared to $115.9 million, or 90.4%
of revenues, for the first quarter of fiscal 1997. The decrease as a percentage
of revenues was primarily due to a decrease in direct labor as a percentage of
revenues. Direct labor as a percentage of revenues was 57.5% in the 1998 period,
compared to 58.8% in the comparable quarter in fiscal 1997.
 
     Gross Profit.  As a result of the foregoing, gross profit for the first
quarter of fiscal 1998 was $13.6 million, or 10.1% of revenues, compared to
$12.4 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 first quarter of fiscal 1998 were $8.6 million,
or 6.4% of revenues, compared to $6.6 million, or 5.1% of revenues, for the
first quarter of fiscal 1997. The increase of $2.0 million was primarily
attributable to incremental costs associated with the assimilation of the Ogden
Acquisition. The majority of these incremental costs were incurred after the
second quarter of fiscal 1997. Salaries and wages increased $1.0 million as a
result of additional headcount required to support the acquired Ogden business
as well as the impact of annual salary
 
                                       34

adjustments effective July 1, 1997. Additionally, office and occupancy costs
increased $724,000 between the comparable periods, primarily as a result of
increased computer lease costs, depreciation expense, temporary help, relocation
expense and recruiting expenses. Professional fees increased $211,000 between
the comparable periods primarily as a result of third party systems programming
costs related to the integration of the Ogden business. Travel and entertainment
expenses increased $222,000 between the comparable periods as a result of
increased air travel and travel-related expenses primarily associated with the
Company's reorganization into Strategic Business Units, effective July 1, 1997.
 
     Amortization of Intangible Assets.  Amortization expense was $1.2 million
in each of the first quarters of fiscal 1998 and fiscal 1997.
 
     Income from Operations.  As a result of the foregoing, income from
operations for the first quarter of fiscal 1998 was $3.8 million or 2.8% of
revenues, compared to $4.6 million, or 3.6% of revenues for the first quarter of
fiscal 1997.
 
     EBITDA.  As a result of the foregoing, EBITDA for the first quarter of
fiscal 1998 was $5.5 million, or 4.1% of revenues, compared to $6.4 million, or
5.0% of revenues, for the first quarter of fiscal 1997.
 
     Interest Expense.  Interest expense for the first quarter of fiscal 1998
was $3.0 million, or 2.2% of revenues, compared to $2.5 million, or 1.9% of
revenues, for the first quarter of fiscal 1997. The increase resulted from
higher borrowings under the Company's revolving credit facilities during the
first quarter of fiscal 1998. 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.
 
     Net Income.  Net income for the first quarter of fiscal 1998 was $578,000,
or 0.4% of revenue, compared to $1.2 million, or 1.0% of revenue, for the first
quarter of fiscal 1997.
 
COMPARISON OF YEARS ENDED JUNE 29, 1997 AND JUNE 30, 1996
 
     Revenues.  Revenues for fiscal 1997 were $533.9 million, an increase of
$435.6 million, compared to revenues of $98.3 million for fiscal 1996. This
increase was primarily attributable to the Ogden Acquisition. Revenues of the
acquired business were approximately $389.0 million for the fiscal year
preceding the acquisition. The balance of the revenue increase of approximately
$46.6 million was attributable to new customer contracts, increases in services
to existing customers and the impact of a full year's revenue from contracts
acquired in the prior year.
 
     Cost of Revenues.  Cost of revenues for fiscal 1997 was $482.5 million, or
90.4% of revenues, compared to $84.2 million, or 85.7% of revenues, for fiscal
1996. The increase as a percentage of revenues was primarily due to a higher
labor component associated with the acquired Ogden business. The higher labor
component is primarily associated with contracts related to certain commercial
and security services and the regional infrastructure necessary to support the
Company's national scope of operations following the Ogden Acquisition.
 
     Gross Profit.  As a result of foregoing, gross profit for fiscal 1997 was
$51.4 million, or 9.6% of revenues, compared to $14.1 million, or 14.3% of
revenues, for fiscal 1996.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses for fiscal 1997 were $31.7 million, or 5.9% of revenues,
compared to $11.5 million, or 11.7% of revenues, for fiscal 1996. The increase
of $20.2 million was primarily attributable to the absorption of overhead costs
associated with the acquired Ogden business. A total of $2.3 million of the
increase in expense represented non-salary related incremental costs in the
accounting, information systems, payroll and human resources departments
attributable to the Ogden Acquisition, including information systems conversion
costs, programming costs, computer lease costs, temporary help and systems
training. The Company also increased headcount in its accounting, payroll and
human resources and information systems departments in order to develop the
infrastructure necessary to support the acquired Ogden business. Payroll costs
and benefits associated with the increased headcount were approximately $450,000
during fiscal 1997. On an annualized basis, such costs are expected to be
approximately $900,000. Selling, general and administrative expenses in 1997
also include $500,000 of non-
 
                                       35
<PAGE>   41
 
recurring charges related to an accounting services agreement between Ogden and
the Company which ended on June 29, 1997.
 
     Amortization of Intangible Assets.  Amortization of intangible assets for
fiscal 1997 was $4.7 million, compared to $551,000 for fiscal 1996.
Approximately $59 million of the $62 million purchase price for the Ogden
business was allocated to intangible assets, which are being amortized over
various lives ranging from seven to 15 years.
 
     Income from Operations.  As a result of the foregoing, income from
operations for fiscal 1997 was $14.9 million, or 2.8% of revenue, compared to
$2.0 million, or 2.1% of revenue, for fiscal 1996.
 
     EBITDA.  As a result of the foregoing, EBITDA for fiscal 1997 was $22.2
million, or 4.2% of revenues, compared to $3.4 million, or 3.5% of revenues for
fiscal 1996.
 
     Interest Expense.  Interest expense for the year ended June 29, 1997 was
$11.5 million, or 2.2% of revenue, compared to $178,000, or 0.2% of revenue for
fiscal 1996. This substantial increase was attributable to indebtedness incurred
in connection with the Ogden Acquisition and the increased working capital
requirements associated therewith. This indebtedness included a $90 million bank
credit facility and $20 million of other subordinated debt. The blended average
interest rate on the bank credit facility was 8.96% as of June 29, 1997.
 
     Net Income.  Net income for fiscal 1997 was $1.2 million, or 0.2% of
revenue, compared to $1.7 million, or 1.8% of revenue, for fiscal 1996.
 
COMPARISON OF YEARS ENDED JUNE 30, 1996 AND JUNE 25, 1995
 
     Revenues.  Revenues for fiscal 1996 were $98.3 million compared to $88.1
million for fiscal 1995, an increase of $10.2 million or 11.6%. The increase was
primarily attributable to a $4.1 million increase in revenues in the Company's
then-existing Schools and College Division (now part of the Company's
Education/Healthcare/Government SBU) and $2.9 million and $2.2 million increases
in revenues from the Company's then-existing Mid-Atlantic and New England
Divisions, respectively.
 
     Cost of Revenues.  Cost of revenues for fiscal 1996 was $84.2 million, or
85.7% of revenues, compared to $74.7 million, or 84.8% of revenues, for fiscal
1995. The increase in cost of revenues as a percentage of revenues was primarily
due to (i) $1.0 million of payroll and payroll-related expenses attributable to
an additional week of operations in fiscal 1996, a 53-week period, that were not
billed in the period to customers who have fixed price contracts, (ii) a $1.4
million increase in workers' compensation and liability insurance premiums
resulting from the transition to a reinsurance program from the Company's
self-insurance arrangement (see "Certain Transactions") and (iii) a $1.0 million
increase in expenses primarily resulting from the increased use of
subcontractors to service several new large customers. These increased costs
were offset in part by $2.1 million in refunds and reversals of reserves
resulting from the Company's favorable insurance claims experience. See Note 5
of Notes to the Company's Combined Consolidated Financial Statements.
 
     Gross Profit.  As a result of the foregoing, gross profit for fiscal 1996
was $14.1 million, or 14.3% of revenues, compared to $13.4 million, or 15.2% of
revenues, for fiscal 1995. The increase in gross profit was attributable to the
increased revenues, offset in part by the higher payroll expenses in fiscal
1996.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses for fiscal 1996 were $11.5 million, or 11.7% of
revenues, compared to $10.2 million, or 11.6% of revenues, for fiscal 1995.
Selling, general and administrative expenses in fiscal 1996 included a $403,000
charge related to the cost of settlement of litigation with a former officer of
the Company, and approximately $124,000 of payroll and payroll-related expenses
related to the extra week of operations described above.
 
     Amortization of Intangible Assets.  Amortization of intangible assets for
fiscal 1996 was $551,000, compared to $535,000 in fiscal 1995. Amortization of
intangible assets in fiscal 1996 included $134,000 related to amortization of a
non-compete agreement signed in January 1996 by a former officer and shareholder
of the
 
                                       36
<PAGE>   42
 
Company. This increase was partially offset by the full amortization of a
non-compete agreement associated with a 1992 acquisition.
 
     Income from Operations.  As a result of the foregoing, income from
operations for fiscal 1996 was $2.0 million, or 2.1% of revenues, compared to
$2.7 million, or 3.0% of revenues, for fiscal 1995.
 
     EBITDA.  As a result of the foregoing, EBITDA for fiscal 1996 was $3.4
million, or 3.5% of revenues,compared to $3.9 million, or 4.4% of revenues, for
fiscal 1995.
 
     Interest Expense.  Interest expense for fiscal 1996 was $178,000, or 0.2%
of revenue, compared to $80,000 or 0.1% of revenue for fiscal 1995. The increase
was attributable to a higher level of borrowings under the Company's revolving
credit facility during fiscal 1996.
 
     Net Income.  Net income for fiscal 1996 was $1.7 million, or 1.8% of
revenues, compared to $2.5 million, or 2.8% of revenues, for fiscal 1995. The
decrease was primarily attributable to the impact of incremental direct labor
expense associated with the 53rd week of operations as described above.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     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.
 
     For the first quarter of fiscal 1998, cash decreased $1.8 million. The
decrease is primarily attributable to $1.9 million of repayments of term debt
during the period. Net cash used for operating and investing activities was
$56,000.
 
     For the first quarter of fiscal 1997, $41.9 million was used for operating
activities and investing activities which consisted of $41.5 million of net cash
used for operating activities and $0.4 million used for investing activities.
Net cash provided by financing activities during the period was $41.9 million,
which primarily represented borrowings under the Company's $48 million line of
credit to fund the working capital requirements related to the Ogden
Acquisition, which occurred on June 28, 1996.
 
     For fiscal 1997, $38.4 million was used for operating and investing
activities which consisted of $36.4 million of net cash used for operating
activities and $2.0 million used for investing activities. For fiscal 1996, the
Company used $46.8 million for operating and investing activities which
consisted of $5.5 million of net cash provided by operating activities and $52.3
million used in investing activities ($51.0 million of which was used for the
Ogden Acquisition). Net cash provided by financing activities in fiscal 1996 was
$46.8 million, primarily resulting from bank indebtedness related to the Ogden
Acquisition.
 
     Capital expenditures were $2.6 million in fiscal 1997. 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 in 1998. The Company's business generally is not seasonal.
 
     The Company's long-term indebtedness consists of borrowings under the
Credit Facility, the Notes and $5.0 million of subordinated indebtedness (which
will rank pari passu in right of payment with the Notes). Under the Credit
Facility, the Company has the ability to borrow up to $45.0 million for working
capital and general corporate purposes, subject to certain conditions. The
Credit Facility, the Indenture 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. See "Description of Other
Indebtedness" and "Description of the Exchange Notes." 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. See "Risk Factors."

YEAR 2000 COMPLIANCE
 
     The Company's computer software systems are licensed from outside vendors.
The Company is in the process of working with its software vendors to determine
the necessary upgrades such that the Company's computer systems will function
properly on and after January 1, 2000. Although such matters will not be within
the Company's direct control, the Company believes that its computer systems
will be "Year 2000 compliant" and that such compliance will not have a material
adverse effect on the Company's results of operations or financial condition.

</TABLE>
 
     The Company believes that opportunities for growth exist in each SBU,
particularly in the Industrial and Education/Healthcare/Government sectors, as a
result of the trend toward outsourcing non-core business functions to a single
source provider. Outsourcing frees the customer from the considerable
administrative and overhead burdens of hiring, training, compensating and
supervising a large, often unionized, labor force that is performing non-core
functions. UNICCO has responded to its customers' outsourcing strategies by
providing an expanded array of services that has evolved from traditional
custodial and building maintenance to higher value added services.
 
     The Company has a customer base of approximately 900 accounts, with no
single customer accounting for more than 3% of revenues during fiscal 1997. The
Company's customer retention rate historically has been high. Customers
representing approximately 75% of fiscal 1997 revenues have been UNICCO
customers for an average of more than six years (excluding revenues and
customers resulting from the Ogden Acquisition in June 1996). On a combined
basis, the Company and Ogden have serviced their 20 largest customers, including
the former Ogden customers, for an average of 10 years. In addition, the Company
has successfully retained over 90% of the customers acquired in the Ogden
Acquisition. UNICCO believes that its strong
 
                                       40
<PAGE>   46
 
reputation and long-term relationships with these customers is a result of a
high level of customer satisfaction. The Company also believes that these
established relationships enhance the Company's knowledge of its customers'
needs and place UNICCO in a strong competitive position to bid on and win new
business opportunities with these customers.
 
BUSINESS STRENGTHS
 
     UNICCO's revenues have increased through a combination of internal growth
and strategic acquisitions. The Company's growth, and its emergence as a leader
in the facilities services market in the United States and Canada, are
attributable to a number of factors, including the following:
 
     High Customer Retention.  The Company benefits from a large, stable base of
customers, including 29 of the Fortune 100 companies, 60 of the Fortune 500
companies and some of the country's most prestigious educational institutions.
The Company's customer base, together with its high customer retention rate,
have provided stable, recurring revenues and have contributed to the Company's
record of consistent profitability.
 
     Established Reputation.  The Company has established a reputation for
quality through almost 50 years of experience in providing dependable, extensive
complex facilities services solutions in a changing business environment. The
Company believes that its established reputation and the breadth of its services
have allowed it to further penetrate its existing customer base as well as
attract new business. The Company plans to enhance its reputation for
dependability and technical expertise by pursuing the highest levels of industry
accreditation.
 
     Singular Focus on Facilities Services.  The Company is focused exclusively
on providing facilities services solutions to its customers, unlike many of its
larger competitors for whom facilities services is an adjunct to their primary
business or one of many other unrelated lines of business. The Company believes
that this exclusive focus gives it a competitive advantage in delivering
dependable, high quality services.
 
     Established North American Presence.  The Company provides services
throughout the United States and Canada from 16 regional offices to customers in
over 40 states and each of the Canadian provinces. The Company believes that it
can leverage this infrastructure to support the marketing and delivery of
services to new customers in strategic geographic areas and to obtain additional
business from major companies that seek to utilize a single source provider
nationwide.
 
     Effective Human Resources and Labor Relations Management.  UNICCO
successfully manages a large and diverse work force of over 19,000 full and
part-time employees. The Company places a major emphasis on attracting,
training, managing, motivating and retaining the human resources necessary to
meet its existing and future business needs. The Company's extensive industry
experience and sophisticated computer-based costing models allow it to
accurately assess the labor requirements of new contracts. UNICCO seeks to
efficiently integrate its customers' existing workforce, thereby minimizing the
traditional issues typically associated with contract inception. In addition,
the Company believes that its experience in managing both union and non-union
work forces has enhanced its ability to grow its business.
 
     Experienced Management Team.  The Company's senior management team has an
average of 20 years of experience in the facilities services industry. The
Company benefits from the quality and depth of its management personnel, who are
dedicated to building customer relationships and delivering quality services to
meet and exceed its customers' needs. Additionally, management has developed
sophisticated databases and costing systems to forecast expenses for individual
customers' service requirements across a variety of service lines. These
proprietary databases enhance UNICCO's ability to effectively price and compete
for customers and contracts.
 
     Successful Acquisition History.  Throughout its 50-year history, UNICCO has
benefited from several successful strategic acquisitions. The Company has
completed three acquisitions since 1990, incorporating operations with revenues
of approximately $20 million, $5 million and $389 million in 1990, 1992 and
1996, respectively. The Company believes that its successful integration of
these acquisitions has positioned it to take advantage of opportunities for
further consolidation within the facilities services industry.

THE COMPANY'S STRATEGY
 
     The Company's objective is to enhance its position as a leading provider of
facility management solutions. The Company's strategy to meet this objective
includes the following initiatives:
 
     Providing Integrated Facilities Solutions.  UNICCO believes that an
attractive opportunity exists to expand the scope of work performed for existing
customers. Cross-selling new services to existing customers represents a
cost-effective method for the Company to achieve revenue growth. The Company
seeks to create partnerships with its customers that enable it to capitalize on
the trend toward outsourcing to single source providers. As part of this
strategy, the Company intends to focus its efforts on increasing the proportion
of its business devoted to delivering higher value added services to its
customers.
 
     Leveraging its National Presence.  UNICCO has established a significant
presence throughout the United States and Canada. The Company believes that it
can substantially increase the number of multi-location and national accounts it
serves by leveraging its existing infrastructure to support the marketing and
delivery of bundled services to new customers that operate multiple locations.
 
     Capitalizing on Outsourcing Initiatives.  The Company believes that it is
well positioned to capitalize on favorable trends in a growing number of
industries toward outsourcing of non-core business functions. Many companies
have increased the volume and types of services they outsource in order to free
their human and capital resources to better focus on their strategic business
initiatives. The Company believes that its established reputation and the
breadth of its services enhance its ability to attract this potential business.
 
     Strategic Business Development.  Through its recent organization into the
four SBUs, the Company is focused on developing specific operating and marketing
strategies targeted to the unique needs of its customers in diverse market
segments. Because of the diversity of UNICCO's existing and potential customer
base, the Company believes that it can position itself to attract higher value
added business by continuing to anticipate its customers' differing needs. The
Company believes that the SBU initiatives it has implemented will enable it to
more effectively leverage its resources to generate new clients and additional
contracts with existing clients.
 
     Growing through Selective Acquisitions.  UNICCO has successfully expanded
its business through internal growth and strategic acquisitions, including the
successful integration of the Ogden Acquisition, and intends to seek additional
opportunities to grow through selective acquisitions. The Company may pursue
acquisitions that add additional services and technical capabilities to market
to its existing customer base, or that facilitate strategic expansion of the
Company's customer base or complement its existing geographic coverage.
 
HISTORY OF THE COMPANY; THE OGDEN ACQUISITION
 
     The Company was founded by the Kletjian family in 1949 and, through early
1996, had grown to become a leading provider of facilities services in the New
England and Mid-Atlantic regions. The Company's expansion resulted from a
combination of internal growth and two strategic acquisitions from Ogden
Corporation. In 1990, the Company acquired a portion of Ogden's New England
facilities services operations representing revenues of approximately $20
million. In 1992, the Company acquired Ogden's Pittsburgh-area facilities
services operations, with revenues of approximately $5 million.
 
     In June 1996, the Company consummated the acquisition of substantially all
of the remaining portion of Ogden's facilities services business, excluding most
New York City operations. The Company acquired the majority of Ogden's North
American facilities management, custodial, plant operation and mechanical
maintenance business, along with the majority of Ogden's North American security
business, as a going concern. As part of the Ogden Acquisition, all of the
senior operating managers of Ogden associated with the acquired operations
became employees of the Company. The Ogden Acquisition more than quadrupled the
amount of the Company's revenues and number of employees and increased the
Company's geographic range to cover most of the United States and Canada.
 
                                       42
<PAGE>   48
 
     The purchase price for the Ogden Acquisition was $62 million, of which $50
million was paid in cash and $12 million was paid in the form of the Ogden Note.
In addition, Ogden agreed not to compete with the Company in the facilities
services business for a period of ten years. The Ogden Acquisition was accounted
for as a purchase.
 
     The Company believes that the Ogden Acquisition has positioned the Company
among the leading United States-based facilities services firms and established
the Company as a full-service provider capable of delivering services to a wide
customer base throughout the United States and Canada. Notable Ogden customers
obtained from the acquisition include Bridgestone/Firestone, Chrysler
Corporation, AT&T, American Home Products, CIGNA, Bell Canada and Lockheed
Martin. The Company has retained over 90% of the customers acquired in the Ogden
Acquisition.
 
INDUSTRY
 
     Over the last several years, trends toward outsourcing have transformed the
traditional facilities services industry. As companies began to realize the
benefits of outsourcing non-core business functions to single source vendors,
the opportunities for companies such as UNICCO to expand into new industries and
obtain new customers have increased. Facilities services companies have expanded
their businesses from providing traditional cleaning services for commercial
property managers and large corporations to performing higher value added
services for companies in the industrial, manufacturing, education and
healthcare sectors. Outsourcing allows companies to:
 
     -       focus on their core competencies to create competitive advantages;
 
     -       re-focus both human and capital resources toward their core
business;
 
     -       reduce operating expenses;
 
     -       share risk and management responsibility;
 
     -       improve quality; and
 
     -       access technical expertise not available internally.
 
     According to The Outsourcing Institute, approximately 80% of U.S. companies
outsource some aspect of their business support services. According to The
Outsourcing Institute, in 1996, U.S. companies spent approximately $100 billion
on outsourcing, reflecting a 100% increase from 1992. Of the $100 billion spent
on outsourcing, an estimated 40% was spent for information technology services,
15% was spent for logistics services, 30% was spent for administrative, human
resources, customer service, transportation, sales and marketing services, and
15% was spent for real estate and physical plant services. These favorable
trends are expected to continue. The Outsourcing Institute estimates that the
U.S. market for outsourcing services will grow to approximately $320 billion by
the year 2001, and that the facilities management segment will grow from
approximately $9.3 billion to approximately $23.0 billion, a compound annual
growth rate of approximately 20%. With UNICCO's geographic coverage and
extensive array of product offerings, the Company believes it is well positioned
to capitalize on these trends.
 
SERVICES
 
     The Company offers a range of integrated facilities management and support
services relating to the operation and maintenance of buildings and plants.
These services are designed to optimize the facility's operating efficiency
while relieving the Company's customers from the management and personnel
burdens associated with non-core functions.
 
     The Company's building operation and maintenance services include
traditional custodial functions such as janitorial and housekeeping services,
and mechanical and plant maintenance, which are provided to customers across the
Company's various market sectors. In connection with the Company's total
facility management concept, the Company provides additional contract building
services in the areas of grounds maintenance, life safety systems, utility
operations, energy management, security, recycling, snow removal and building
systems controls.
 
                                       43
<PAGE>   49
 
     In addition to providing services which are directly related to the
operation, safety and maintenance of the facility, the Company also supplies
certain facility support services and a combination of manufacturing and
administrative support functions to its customers. In response to both
outsourcing initiatives instituted by certain of its customers and the Company's
efforts to provide customers with cost effective solutions for non-core
functions, the Company has partnered with many organizations in supplying
process management and staffing in the areas of production support, warehousing,
distribution, shipping and receiving, preventive and predictive maintenance of
manufacturing equipment, vehicle maintenance, waste water treatment and chemical
distribution systems maintenance, and reprographic and mailroom operations
support.
 
     In order to supply seamless integrated services to a broad base of
customers and facilities, the Company also selects, manages and integrates
services provided by third parties into the Company's overall portfolio of
services. For example, the Company is able to provide sub-contracted services in
areas such as facility renovation, facility planning, space design and office
relocation to relieve its customers of individually searching for and
contracting with suppliers of these services.

CUSTOMERS
 
     The Company's customer base is diverse in its geographic coverage, industry
sector representation, category of facility and type of service provided. The
Company has approximately 900 active customer accounts, including 29 of the
Fortune 100 and 60 of the Fortune 500 companies, operating in a wide variety of
business sectors including commercial real estate, banking, insurance, consumer
products, automotive and heavy equipment manufacturing, pharmaceuticals,

such as museums and sports facilities.
 
     The Company's revenue stream is diverse, with no single customer accounting
for more than 3% of the Company's revenues in fiscal 1997. Management does not

CONTRACTS
 
     The Company's business is generally conducted under written contracts with
its customers. Contracts vary in type and duration, with a majority having a
term of one to three years, often with automatic renewal clauses unless either
party elects to terminate. Most of the Company's contracts are subject to
termination without penalty at the option of the customer, or by either the
Company or the customer, upon 30 to 90 days' notice. The Company's experience,
as evidenced by its history of long-standing customer relationships, is that
while contractual elements may be re-negotiated, termination clauses are rarely
exercised. On those occasions when the Company has lost a customer, it is most
commonly as a result of the contract being re-bid upon expiration rather than
the exercise of a termination clause. The Company does not view its business
prospects as being particularly dependent on its written contracts, but rather
on the strength of its customer relationships and the consistency and quality of
service delivered.
 
     The Company structures its service contracts under three principal methods:
fixed price, cost plus fixed fee and hourly billing. All contracts are based
upon a defined scope and frequency of services to be provided. Under fixed price
contracts, which currently account for approximately 25% of the Company's
revenues, the customer agrees to a fixed dollar amount for all labor and
non-labor costs. Cost plus fixed fee contracts, which currently account for
approximately 63% of the Company's revenues, provide for the customer to be
billed for labor and non-labor costs, allocated overhead and a negotiated fee
based upon these costs. Hourly billing rate contracts, which currently account
for approximately 12% of the Company's revenues, are used primarily in providing
security services and provide for actual hours worked to be billed at
pre-determined hourly rates. In certain instances, modifications to the cost
plus fixed fee contracts are structured to include an incentive fee or shared
cost savings based upon operating efficiencies obtained.
 
     Certain of the Company's contracts, particularly government contracts,
require the Company to post a performance bond and/or payment bond as a
condition of contract award. Total performance and/or payment bonds outstanding
at August 30, 1997 were $6.3 million. The Company has never had a claim made
under any performance or payment bond.
 
SALES AND MARKETING
 
     The Company's marketing efforts are designed to create a cohesive,
company-wide image and strategy as well as to provide individual focus to each
of the Company's SBUs. Company-wide marketing efforts are coordinated by a
marketing department under the direction of the Company's recently established
position of Vice President -- Marketing who is also responsible for sales
process management, tactical marketing and strategic planning and development.
 
     As a result of the Company's emergence as a leader in the industry and its
reputation for delivering quality services, the Company is frequently invited to
bid on new major facility service contracts in the United States and Canada. The
Company is able to respond to these requests as a result of its ability to
coordinate sales, technical and financial resources to develop comprehensive
proposals addressing and delivering all aspects of customers' service
requirements at a competitive price. The Company's marketing and planning group
has implemented initiatives to sell additional higher margin services to
UNICCO's existing customers, targeting industries and geographic areas which the
Company believes have the highest propensity to outsource services and which
involve large, complex, multi-site operations.
 
COMPETITION
 
     The facility services industry is characterized by a combination of a small
number of large national organizations, none of which has a dominant market
share, as well as numerous smaller companies providing a narrow range of
services in a limited geographic area. While the Company operates throughout the
United States and Canada, its services are delivered at the local level and as a
result it competes with both national organizations as well as the smaller
contractors. There are many firms that provide core janitorial, custodial or
housekeeping services, principally in the Company's commercial market sector, on
either a regional basis or limited to a small number of geographically proximate
cities or contiguous states. In addition, the Company
 
                                       46
<PAGE>   52
 
faces competition from large national firms that have branch offices or
operating locations in major cities established to service the local business
community.
 
     In the broader market for providing bundled facility management services to
customers or for multi-site/multi-function contracts, as well as outsourced
manufacturing and administrative support services, the Company competes
primarily against large national firms. The Company believes there are a limited
number of companies that offer the range of services to both local and national
accounts as are being provided by the Company. ABM Industries, Aramark, Fluor
Corp., ISS-International Service Systems, Johnson Controls, Marriott
Corporation, Pinkerton and Service Master, among others, all supply similar
services to customers in the Company's principal market sectors. These
organizations generally have substantially greater financial and marketing
resources than the Company.
 
     The Company believes that the principal competitive factors in the market
segments in which it operates are quality of service, cost, capability to
provide a broad range of fully integrated services, geographic scale of
operations and the ability to establish and maintain long-term customer
relationships. The Company believes that it competes favorably with respect to
each of these factors.
 
EMPLOYEES
 
     The Company employs over 19,000 employees of which approximately 58% are
full time and approximately 42% are part-time. Approximately 44% of the
Company's work force is unionized under more than 170 different union contracts.
The Company has not experienced any strikes or work stoppages, and management
generally considers its relationships with its employees and its unions to be
satisfactory.
 
FACILITIES
 
     The following table sets forth the Company's principal office facilities
throughout North America. The Company also has a number of smaller offices in
other cities, all of which are leased. The majority of the Company's employees
are engaged in providing services directly to customers at the customers'
facilities. Accordingly, the Company does not consider any of these locations to
be material to its operations as a whole.

TRUSTEE COMPENSATION
 
     Steven C. Kletjian, Richard J. Kletjian and Robert P. Kletjian receive no
additional compensation for serving as Trustees of the Company. Sharkay
Kletjian, a Trustee of the Company, received aggregate compensation of $172,566
during fiscal 1997 in her capacity as an employee of the Company.
 
EMPLOYMENT AGREEMENTS
 
     In connection with the Ogden Acquisition in June 1996, the Company entered
into employment agreements with former Ogden managers of the acquired
operations, including Messrs. McGillicuddy, Scoble, Barrett, Simon, Walters and
Struthers, each for a term of three years. The employment agreements provide for
a base salary and an annual bonus based on the Company's operating income before
debt service, as well as benefits commensurate with those provided to the
Company's other senior managers. These agreements may be terminated by the
Company for cause, as defined therein. Each agreement contains a confidentiality
clause that survives for two years beyond termination of employment.
 
EMPLOYEE BENEFITS
 
     The Company is in the process of implementing a new management incentive
plan under which a portion of the performance-based incentive bonuses payable to
senior management will be paid in the form of equity-based interests in UNICCO.
The bonuses will be determined based on both the Company's performance and the
performance of the applicable SBU. The Company is also considering the
implementation of a stock option plan pursuant to which employees, trustees,
directors and other key persons at the Company may be granted options to
purchase non-voting shares of UNICCO.

                                SHARE OWNERSHIP
 
     Under UNICCO's Declaration of Trust, UNICCO may issue an unlimited number
of shares of beneficial interest. The Trustees may determine the classes and
series of such shares and may designate the relative designations, preferences,
privileges, voting powers and restrictions applicable to the shares of each such
class and series. As of the date hereof, the outstanding securities of UNICCO
consist of an aggregate of 1,054 common shares of beneficial interest,
consisting of 1,000 voting common shares and 54 non-voting common shares.
 
     The following table sets forth the beneficial and record ownership of
UNICCO's voting and non-voting common shares of beneficial ownership, taken

     The Company has entered into a Share Purchase Agreement with holders of
non-voting shares pursuant to which the Company must redeem the shares at the
then-current book value of the shares (as defined therein) in the event that the

                              CERTAIN TRANSACTIONS
 
     In connection with the Ogden Acquisition in June 1996, the shareholders of
UNICCO organized a sister corporation known as USC, Inc., which acquired all of
the outstanding capital stock of the two Ogden subsidiaries that conducted
Ogden's government and security business, and a portion of the capital stock of
Ogden's Canadian subsidiary. The purpose of this transaction was to facilitate
the acquisition of Ogden's government contracts and security permits and
licenses. A sister company rather than a subsidiary of UNICCO was utilized
because, as a subchapter S company under the Internal Revenue Code (the "Code")
as then in effect, UNICCO could not have any subsidiaries. As of January 1,
1997, the Code has been amended to permit "subchapter S" companies to have
subsidiaries. Accordingly, in connection with the Offering, the shareholders of
the Company contributed their interests in USC, Inc. to UNICCO, as a result of
which all of the operations of the Company will be conducted through UNICCO and
its subsidiaries.
 
     A component of the Company's operating expenses consists of insurance
premiums for workers' compensation and general liability insurance. In May 1995,
the Company's shareholders organized Ashmont Insurance Company, Limited, a
Bermuda corporation ("Ashmont"), as a captive insurance company. Premiums for
workers' compensation and general liability insurance are paid by the Company to
Liberty Mutual Insurance Company and one of its subsidiaries, the fronting
carrier ("Liberty"). After deducting pre-determined fees for administration,
claims processing and taxes, Liberty remits the net premiums to Ashmont pursuant
to a re-insurance agreement. Ashmont, as re-insurer, then reimburses Liberty for
insurance losses paid on a monthly basis. Net insurance premiums received by
Ashmont pursuant to this arrangement aggregated $2.9 million, $2.5 million and
$5.6 million for fiscal 1995, fiscal 1996 and fiscal 1997, respectively.
Workers' compensation insurance premiums are based on statutory rates within the
states that the Company operates, adjusted for the Company's claims experience;
accordingly, management believes that these insurance premiums are consistent
with the premiums that would be paid for comparable insurance coverage obtained
on an arm's-length basis.
 
     In connection with the Ogden Acquisition in June 1996, the Company borrowed
$3 million from the Company's shareholders. The notes bore interest at 15%,
which was payable in-kind until the notes were to mature in October 2001. The
Company used a portion of the net proceeds of the Offering to repay such notes,
including accrued interest. In addition, upon the repayment of the Ogden Note,
Steven C. Kletjian, the Company's Chief Executive Officer and principal
shareholder, was released from a limited recourse guarantee of the Ogden Note
and the pledge of Mr. Kletjian's shares of Ashmont which secured such guarantee.
See "Use of Proceeds."
 
     The Company was indebted under a note payable to Sharkay Kletjian, a
Trustee of the Company, in the aggregate principal amount of approximately
$282,000 at June 29, 1997. Interest on this Note was payable at a rate of 20%
per annum. The Note was repaid on September 3, 1997.
 
     The Company holds notes receivable aggregating approximately $646,000 from
five of its shareholders consisting primarily of demand notes that bear interest
at an average Applicable Federal Rate (5.68% at June 29, 1997). The Company
earned interest income of approximately $83,000, $77,000 and $56,000 related to
these loans during fiscal 1995, fiscal 1996 and fiscal 1997, respectively.
Interest receivables related to those notes were approximately $312,000 at June
29, 1997.
 
     On June 24, 1996, the Company loaned one of its shareholders approximately
$217,000 to purchase 27 non-voting common shares of beneficial interest. This
loan bears interest at the applicable federal rate and matures on July 1, 2001.

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
CREDIT FACILITY
 
     In connection with the Transactions, the Company and BankBoston, N.A.
("BankBoston") entered into a $45 million senior secured revolving credit
facility (the "Credit Facility") documented in the form of an amendment to the
Company's existing credit facility. Subject to compliance with certain financial
covenants and the satisfaction of customary borrowing conditions, UNICCO and its
subsidiaries, as co-borrowers, will be permitted to borrow up to an aggregate of
$45 million of revolving credit loans and up to a sublimit of $2.5 million in
letters of credit under the Credit Facility. The Company's borrowing capacity
under the Credit Facility is limited to a borrowing base of up to 80% of the
Company's eligible accounts receivable (as defined in the Credit Facility),
which as of June 29, 1997 was in excess of the maximum amount of borrowings
available under the Credit Facility. The Credit Facility is secured by
substantially all of the Company's assets. Borrowings under the Credit Facility
will represent Senior Debt under the Indenture. Moreover, a default under the
Indenture will result in a cross-default under the Credit Facility.
 
     The ability of the Company to borrow under the Credit Facility will be
subject to, among other things, compliance with covenants and financial ratios
contained in the Credit Facility. Borrowings under the Credit Facility will
mature and be payable in October 2002.
 
     The Credit Facility will bear interest, at the Company's option, at the
Alternate Base Rate (as defined below) or a Eurodollar rate, plus specified
margins based on the ratio of the Company's Total Funded Debt to EBITDA (each as
defined therein). The Alternate Base Rate will be the greater of BankBoston's
base rate as announced from time to time and the federal funds effective rate
plus 0.50%. The applicable margins were initially set at the Alternate Base Rate
plus 0.50% or the Eurodollar rate plus 2.00%.
 
     The Credit Facility contains covenants and provisions that restrict, among
other things, the Company's and its subsidiaries' ability to (i) incur
additional indebtedness; (ii) incur liens on their property; (iii) redeem
subordinated debt, including the Notes; (iv) make capital expenditures; (v)
engage in certain sales of assets; (vi) engage in acquisitions that do not meet
specified criteria; and (vii) engage in certain transactions with affiliates.
The Credit Facility also requires the Company to maintain certain financial
ratios which become more stringent over the life of the facility, including (i)
minimum fixed charge coverage ratios, (ii) minimum interest coverage ratios and
(iii) maximum ratios of total debt to EBITDA.
 
MCRC NOTE
 
     In order to finance a portion of the Ogden Acquisition in June 1996, the
Company issued a $5 million note payable to Massachusetts Capital Resource
Company ("MCRC"). This note (the "MCRC Note") bears interest at the rate of 14%
per annum and is due in September 2001. The MCRC Note is expressly subordinated
to the Company's indebtedness under the Credit Facility, and will rank pari
passu in right of payment with the Notes.
 
     The MCRC Note requires quarterly payments of interest only. Prepayment of
the principal amount of the MCRC Note is not permitted prior to July 1999.
Thereafter, the Company may redeem up to $250,000 in principal amount of the
MCRC Note on a quarterly basis, without premium, and may redeem additional
principal amounts upon payment of a premium equal to 10% of the additional
principal amount so redeemed.
 
     The MCRC Note was issued under a Note Purchase Agreement containing
representations, warranties and covenants customary for subordinated debt
financings of this type. In connection with the Transactions, the MCRC Note
Purchase Agreement was amended to eliminate the covenants requiring the Company
to maintain certain financial ratios, and to conform certain other covenants,
including those limiting restricted payments and the incurrence of additional
indebtedness, to those contained in the Indenture. In connection with this
amendment, MCRC released Steven C. Kletjian, the Company's Chief Executive
Officer and principal shareholder, from a limited recourse guarantee of the MCRC
Note and released a pledge of Mr. Kletjian's shares of Ashmont which secured
such guarantee.

<PAGE>   61
 
                       DESCRIPTION OF THE EXCHANGE NOTES
 
GENERAL
 
     The Exchange Notes will be issued pursuant to the Indenture among the
Issuers, the Guarantors and State Street Bank and Trust Company, as trustee (the
"Trustee"). The terms of the Exchange Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). Upon the
effectiveness of the Registration Statement of which this Prospectus forms a
part, the Indenture will be subject to and governed by the Trust Indenture Act.
The Notes are subject to all such terms, and Holders of Notes are referred to
the Indenture and the Trust Indenture Act for a statement thereof. The following
summary of the material provisions of the Indenture does not purport to be
complete and is qualified in its entirety by reference to the Indenture,
including the definitions therein of certain terms used below. Copies of the
Indenture and Registration Rights Agreement will be made available as set forth
under "-- Additional Information." The definitions of certain terms used in the
following summary are set forth below under "-- Certain Definitions." For
purposes of this "Description of the Exchange Notes," the term "Company" refers
only to UNICCO Service Company and not to any of its Subsidiaries.
 
     The Exchange Notes will be general unsecured obligations of the Issuers and
will be subordinated in right of payment to all existing and future Senior Debt
of the Issuers. As of September 28, 1997, after giving pro forma effect to the
offering of the Series A Notes and the use of proceeds therefrom, the Issuers
would have had approximately $3.4 million of Senior Debt outstanding, consisting
of outstanding borrowings under the Credit Facility. In addition, the Issuers
would have had $41.6 million of additional borrowings available under the Credit
Facility. The Indenture permits the Issuers to incur additional indebtedness,
including additional Senior Debt, subject to certain restrictions. See "--
Certain Covenants -- Incurrence of Indebtedness and Issuance of Preferred
Stock."
 
     UNICCO Finance is a wholly owned subsidiary of the Company that was
incorporated in Delaware for the purpose of serving as a co-issuer of the Series
A Notes and the Exchange Notes in order to facilitate the Offering. The Company
believes that certain prospective purchasers of the Series A Notes might have
been restricted in their ability to purchase debt securities of business trusts,
such as the Company, unless such debt securities are jointly issued by a
corporation. UNICCO Finance will not have any substantial operations or assets
and will not have any revenues. As a result, prospective purchasers of the
Exchange Notes should not expect UNICCO Finance to participate in servicing the
interest and principal obligations on the Exchange Notes.
 
     All of the Company's Subsidiaries (other than UNICCO Finance) are
Restricted Subsidiaries. However, under certain circumstances, the Company is
able to designate current or future Subsidiaries (other than UNICCO Finance) as
Unrestricted Subsidiaries. Unrestricted Subsidiaries are not subject to many of
the restrictive covenants set forth in the Indenture. The Issuers' payment
obligations under the Exchange Notes will be guaranteed, on a senior
subordinated basis, by all of the Company's Domestic Restricted Subsidiaries.
See "-- Subsidiary Guarantees."
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Exchange Notes will be limited in aggregate principal amount to $150.0
million and will mature on October 15, 2007. Interest on the Exchange Notes will
accrue at the rate of 9 7/8% per annum and will be payable semi-annually in
arrears on April 15 and October 15 of each year, commencing on April 15, 1998,
to Holders of record on the immediately preceding April 1 and October 1.
Interest on the Exchange Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of
original issuance. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Principal of and premium, interest and
Liquidated Damages, if any, on the Exchange Notes will be payable at the office
or agency of the Issuers maintained for such purpose or, at the option of the
Issuers, payment of interest and Liquidated Damages may be made by check mailed
to the Holders of the Exchange Notes at their respective addresses set forth in
the register of Holders of Exchange Notes; provided that all payments of
principal, premium, interest and Liquidated Damages with respect to Exchange
Notes the Holders of which have given wire transfer instructions in writing to
the Trustee will be required to be made by
 
                                       56
<PAGE>   62
 
wire transfer of immediately available funds to the accounts specified by the
Holders thereof. Until otherwise designated by the Issuers, the Issuers' office
or agency will be the office of the Trustee maintained for such purpose. The
Exchange Notes will be issued in denominations of $1,000 and integral multiples
thereof.
 
SUBORDINATION
 
     The payment of principal of and premium, interest and Liquidated Damages,
if any, on the Exchange Notes will be subordinated in right of payment, as set
forth in the Indenture, to the prior payment in full in cash or Cash Equivalents
of all Senior Debt of the Issuers.
 
     Upon any distribution to creditors of either Issuer in a liquidation or
dissolution of such Issuer or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Issuer or its property, an
assignment for the benefit of creditors or any marshalling of either Issuer's
assets and liabilities, the holders of Senior Debt of such Issuer will be
entitled to receive payment in full in cash or Cash Equivalents of all
Obligations due in respect of such Senior Debt (including interest after the
commencement of any such proceeding at the rate specified in the documents
governing the applicable Senior Debt) before the Holders of Exchange Notes will
be entitled to receive any payment with respect to the Exchange Notes, and until
all Obligations with respect to Senior Debt are paid in full in cash or Cash
Equivalents, any distribution to which the Holders of Exchange Notes would be
entitled shall be made to the holders of Senior Debt (except that Holders of
Exchange Notes may receive Permitted Junior Securities and payments made from
the trust described under "-- Legal Defeasance and Covenant Defeasance").
 
     The Issuers also may not make any payment upon or in respect of the
Exchange Notes (except in Permitted Junior Securities or from the trust
described under "-- Legal Defeasance and Covenant Defeasance") if (i) a default
in the payment of the principal of or premium, or interest on any Designated
Senior Debt occurs and is continuing beyond any applicable period of grace or
(ii) any other default occurs and is continuing with respect to any Designated
Senior Debt that permits holders of the Designated Senior Debt as to which such
default relates to accelerate its maturity and the Trustee receives a notice of
such default (a "Payment Blockage Notice") from the Company or the holders of
such Designated Senior Debt. Payments on the Exchange Notes may and shall be
resumed (a) in the case of a payment default, upon the date on which such
default is cured or waived pursuant to the terms of such Designated Senior Debt
and (b) in case of a nonpayment default, the earlier of the date on which such
nonpayment default is cured or waived pursuant to the terms of such Designated
Senior Debt or 179 days after the date on which the applicable Payment Blockage
Notice is received, unless the maturity of any Designated Senior Debt has been
accelerated. No new period of payment blockage may be commenced unless and until
360 days have elapsed since the effectiveness of the immediately prior Payment
Blockage Notice. No nonpayment default that existed or was continuing on the
date of delivery of any Payment Blockage Notice to the Trustee shall be, or be
made, the basis for a subsequent Payment Blockage Notice.
 
     The Indenture further requires that the Issuers promptly notify holders of
Senior Debt if payment of the Exchange Notes is accelerated because of an Event
of Default.
 
     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency, Holders of Exchange Notes may recover less
ratably than creditors of the Issuers who are holders of Senior Debt, and may
not recover any amounts owed to them in respect of the Exchange Notes. As of
September 28, 1997, after giving pro forma effect to the offering of the Series
A Notes and the use of proceeds therefrom, the Issuers would have had
approximately $3.4 million of Senior Debt outstanding, consisting of outstanding
borrowings under the Credit Facility. In addition, the Issuers would have had
$41.6 million of additional borrowings available under the Credit Facility. The
Issuers will be able to incur additional Senior Debt in the future, subject to
certain limitations. See "Risk Factors -- Subordination of the Exchange Notes"
and "-- Certain Covenants -- Incurrence of Indebtedness and Issuance of
Preferred Stock."
 
SUBSIDIARY GUARANTEES
 
     The Issuers' payment obligations under the Exchange Notes will be
guaranteed by all of the Company's existing Domestic Restricted Subsidiaries.
The Guarantee of each Domestic Restricted Subsidiary will be
 
                                       57
<PAGE>   63
 
subordinated in right of payment to all existing and future Senior Debt of such
Domestic Restricted Subsidiary to the same extent as the Exchange Notes are
subordinated to Senior Debt of the Issuers. See "-- Subordination." As of
September 28, 1997, after giving effect to the offering of the Series A Notes
and the use of proceeds therefrom, the Company's Restricted Subsidiaries had
approximately $3.4 million of Senior Debt outstanding, consisting of guarantees
of borrowings under the Credit Facility. The Indenture permits the Company's
Subsidiaries to incur additional indebtedness, including additional Senior Debt,
subject, in the case of the Company's Restricted Subsidiaries, to certain
restrictions. See "-- Certain Covenants -- Incurrence of Indebtedness and
Issuance of Preferred Stock."
 
     The Indenture provides that in the event of a sale or other disposition of
all of the assets of any Domestic Restricted Subsidiary, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the capital
stock of any Domestic Restricted Subsidiary (other than to the Company or
another Domestic Restricted Subsidiary), or in the case the Company designates a
Domestic Restricted Subsidiary to be an Unrestricted Subsidiary in accordance
with the Indenture, then such Domestic Restricted Subsidiary will be released
and relieved of any obligations under its guarantee; provided that the Net
Proceeds of any such sale or other disposition are applied in accordance with
the applicable provisions of the Indenture. See "-- Repurchase at Option of
Holders -- Asset Sales."
 
OPTIONAL REDEMPTION
 
     The Exchange Notes will not be redeemable at the Issuers' option prior to
October 15, 2002. Thereafter, the Exchange Notes will be subject to redemption
at any time at the option of the Issuers, in whole or in part, upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below, plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on October 15, of the
years indicated below:

</TABLE>
 
     Notwithstanding the foregoing, prior to October 15, 2000, the Issuers may
redeem up to an aggregate of $33.0 million in principal amount of Exchange Notes
at a redemption price of 109.875% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the redemption
date, with the net cash proceeds of an initial public offering of common equity
of the Company; provided that (i) at least $72.0 million in principal amount of
the Exchange Notes remains outstanding immediately after the occurrence of such
redemption and (ii) notice of such redemption shall be given within 90 days of
the date of the consummation of such initial public offering.
 
SELECTION AND NOTICE
 
     If less than all of the Exchange Notes are to be redeemed at any time,
selection of Exchange 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 Exchange Notes are listed, or, if the Exchange Notes are
not so listed, on a pro rata basis, by lot or by such method as the Trustee
shall deem fair and appropriate; provided that no Exchange Notes of $1,000 or
less shall be redeemed in part. Notices of redemption shall be mailed by first
class mail at least 30 but not more than 60 days before the redemption date to
each Holder of Exchange Notes to be redeemed at its registered address. Notices
of redemption may not be conditional. If any Exchange Note is to be redeemed in
part only, the notice of redemption that relates to such Exchange Note shall
state the portion of the principal amount thereof to be redeemed. A new Exchange
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 Exchange
Note. Exchange Notes called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrue on
Exchange Notes or portions of them called for redemption.

MANDATORY REDEMPTION
 
     Except as set forth below under "-- Repurchase at the Option of Holders,"
the Issuers are not required to make mandatory redemption or sinking fund
payments with respect to the Exchange Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
  CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Issuers will be obligated
to make an offer (a "Change of Control Offer") to each Holder of Exchange Notes
to repurchase all or any part (equal to $1,000 or an integral multiple thereof)
of such Holder's Exchange Notes at an offer price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following a Change of Control, the Issuers will mail a
notice to each Holder describing the transaction or transactions that constitute
the Change of Control and offering to repurchase Exchange Notes on the date
specified in such notice, which date shall be no earlier than 30-days and no
later than 60 days from the date such notice is mailed (the "Change of Control
Payment Date"), pursuant to the procedures required by the Indenture and
described in such notice. The Issuers will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of the Exchange Notes as a result of a Change of Control.
 
     On the Change of Control Payment Date, the Issuers will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Exchange Notes
or portions thereof so tendered and (iii) deliver or cause to be delivered to
the Trustee the Exchange Notes so accepted together with an officers'
certificate stating the aggregate principal amount of Exchange Notes or portions
thereof being purchased by the Issuers. The Paying Agent will promptly mail to
each Holder of Exchange Notes so tendered the Change of Control Payment for such
Exchange Notes, and the Trustee will promptly authenticate and mail (or cause to
be transferred by book entry) to each Holder a new Exchange Note equal in
principal amount to any unpurchased portion of the Exchange Notes surrendered,
if any; provided that each such new Exchange Note will be in a principal amount
of $1,000 or an integral multiple thereof. The Indenture will provide that,
prior to complying with the provisions of this covenant, but in any event within
90 days following a Change of Control, the Issuers will either repay all
outstanding Senior Debt or obtain the requisite consents, if any, under all
agreements governing outstanding Senior Debt to permit the repurchase of
Exchange Notes required by this covenant. The Issuers will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.
 
     The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the Exchange Notes to require that the
Issuers repurchase or redeem the Exchange Notes in the event of a takeover,
recapitalization or similar transaction.
 
     The Credit Facility prohibits, and future credit agreements or other
agreements relating to Senior Debt to which the Issuers become a party may
prohibit, the Issuers from purchasing any Exchange Notes following a Change of
Control and/or provide that 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 Issuers are prohibited from purchasing Exchange Notes,
the Issuers could seek the consent of their lenders to the purchase of Exchange
Notes or could attempt to refinance the borrowings that contain such
prohibition. If the Issuers do not obtain such a consent or repay such
borrowings, the Issuers will remain prohibited from purchasing Exchange Notes.
The Issuers' failure to purchase tendered Exchange Notes following a Change of
Control would constitute an Event of Default under the Indenture which would, in
turn, constitute as default under the Credit Facility. In such circumstances,
the subordination provisions in the Indenture would likely restrict payments to
the Holders of Exchange Notes. See "-- Subordination."
 
     The Issuers will not be required to make a Change of Control Offer
following a Change of Control if a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with
 
                                       59
<PAGE>   65
 
the requirements set forth in the Indenture applicable to a Change of Control
Offer made by the Issuers and purchases all Exchange Notes validly tendered and
not withdrawn under such Change of Control Offer.
 
  ASSET SALES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the
Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value (evidenced by a resolution of the Board of Directors set forth in an
officers' certificate delivered to the Trustee) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 80% of the
consideration therefor received by the Company or such Restricted Subsidiary is
in the form of cash; provided that the amount of (a) any liabilities (as shown
on the Company's or such Restricted Subsidiary's most recent balance sheet) of
the Company or such Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any Guarantee
thereof) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases the Company or such Restricted
Subsidiary from further liability and (b) any securities, notes or other
obligations received by the Company or such Restricted Subsidiary from such
transferee that are immediately converted by the Company or such Restricted
Subsidiary into cash (to the extent of the cash received) shall be deemed to be
cash for purposes of this provision.
 
     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (i) to repay Senior Debt
(and to correspondingly reduce commitments with respect thereto in the case of
revolving borrowings) or (ii) to the acquisition of a controlling interest in
another business, the making of a capital expenditure or the acquisition of
other long-term assets. Pending the final application of any such Net Proceeds,
the Company may temporarily reduce Senior Debt or otherwise invest such Net
Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds
from Asset Sales that are not applied or invested as provided in the first
sentence of this paragraph will be deemed to constitute "Excess Proceeds." When
the aggregate amount of Excess Proceeds exceeds $5.0 million, the Issuers will
be required to make an offer to all Holders of Exchange Notes (an "Asset Sale
Offer") to purchase the maximum principal amount of Exchange Notes that may be
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase, in accordance
with the procedures set forth in the Indenture. To the extent that the aggregate
amount of Exchange Notes tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, the Company may use any remaining Excess Proceeds for
general corporate purposes. If the aggregate principal amount of Exchange Notes
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Exchange Notes to be purchased on a pro rata basis.
Upon completion of an Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.
 
CERTAIN COVENANTS
 
  RESTRICTED PAYMENTS
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay
any dividend or make any other payment or distribution on account of the
Company's Equity Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the Company) or to any
direct or indirect holders of the Company's Equity Interests in their capacity
as such (other than dividends or distributions (a) payable in Equity Interests
(other than Disqualified Stock) of the Company or (b) to the Company or any
Wholly Owned Restricted Subsidiary of the Company); (ii) purchase, redeem or
otherwise acquire or retire for value (including without limitation, in
connection with any merger or consolidation involving the Company) any Equity
Interests of the Company or any direct or indirect parent of the Company (other
than any such Equity Interests owned by the Company or any Wholly Owned
Restricted Subsidiary of the Company); (iii) make any payment on or with respect
to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness of the Company or any Restricted Subsidiary that is subordinated to
the Exchange Notes or any Guarantee thereof, except a payment of interest or
principal at Stated Maturity; or (iv) make any Restricted Investment (all such
payments and
 
                                       60
<PAGE>   66
 
other actions set forth in clauses (i) through (iv) above being collectively
referred to as "Restricted Payments"), unless, at the time of and after giving
effect to such Restricted Payment:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and
 
          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     the covenant described below under caption "-- Incurrence of Indebtedness
     and Issuance of Preferred Stock;" and
 
          (c) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the Closing Date (excluding Restricted Payments
     permitted by clause (ii) through (v) of the next succeeding paragraph), is
     less than the sum of (i) 50% of the Consolidated Net Income of the Company
     for the period (taken as one accounting period) from the beginning of the
     first fiscal quarter commencing after the Closing Date to the end of the
     Company's most recently ended fiscal quarter for which internal financial
     statements are available at the time of such Restricted Payment (or, if
     such Consolidated Net Income for such period is a deficit, less 100% of
     such deficit), plus (ii) 100% of the aggregate net cash proceeds received
     by the Company from the issue or sale since the date of the Indenture of
     Equity Interests of the Company (other than Disqualified Stock) or of
     Disqualified Stock or debt securities of the Company that have been
     converted into such Equity Interests (other than Equity Interests (or
     Disqualified Stock or convertible debt securities) sold to a Subsidiary of
     the Company and other than Disqualified Stock or convertible debt
     securities that have been converted into Disqualified Stock), plus (iii)
     50% of any dividends received by the Company or a Wholly Owned Restricted
     Subsidiary after the date of the Indenture from an Unrestricted Subsidiary
     of the Company, to the extent that such dividends were not otherwise
     included in Consolidated Net Income of the Company for such period.
 
     The foregoing provisions will not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at the date of
declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
or any Restricted Subsidiary in exchange for, or out of the net cash proceeds of
the substantially concurrent sale (other than to a Subsidiary of the Company)
of, other Equity Interests of the Company (other than any Disqualified Stock);
provided that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement, defeasance or other acquisition shall
be excluded from clause (c)(ii) of the preceding paragraph; (iii) the
defeasance, redemption, repurchase or other acquisition of subordinated
Indebtedness with the net cash proceeds from an incurrence of Permitted
Refinancing Indebtedness; (iv) for any period that the Company is treated as an
"S corporation" or a partnership for federal income tax purposes, distributions
to shareholders of the Company in an amount not to exceed the Tax Amount for
such period; (v) the redemption, retirement or defeasance of indebtedness with
the net proceeds of this Offering as contemplated under "Use of Proceeds;" and
(vi) the repurchase, redemption or other acquisition or retirement for value of
any Equity Interests of the Company or any Restricted Subsidiary of the Company
held by any member of the Company's (or any of its Restricted Subsidiaries')
management or Board of Directors pursuant to any management equity subscription
agreement, shareholders' agreement, equity incentive plan, stock option
agreement or other similar agreement; provided that the aggregate price paid for
all such repurchased, redeemed, acquired or retired Equity Interests under this
clause (vi) shall not exceed the sum of (a) $500,000 in any twelve-month period
plus (b) the aggregate net proceeds received by the Company from the issuance
after the Closing Date of Equity Interests of the Company to members of
management or the Board of Directors of the Company or any of its Restricted
Subsidiaries (provided that such net proceeds shall be excluded from clause
(c)(ii) of the preceding paragraph), and, in each case, no Default or Event of
Default shall have occurred and be continuing immediately after such
transaction.
 
                                       61
<PAGE>   67
 
     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined in good
faith by the Board of Directors whose resolution with respect thereto shall be
delivered to the Trustee. Not later than the date of making any Restricted
Payment, the Company shall deliver to the Trustee an officers' certificate
stating that such Restricted Payment is permitted and setting forth the basis
upon which the calculations required by the covenant "Restricted Payments" were
computed.
 
     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated will be deemed to be Restricted Payments at the
time of such designation and will reduce the amount available for Restricted
Payments under the first paragraph of this covenant. All such outstanding
Investments will be deemed to constitute Investments in an amount equal to the
greatest of (i) the net book value of such Investments at the time of such
designation, (ii) the fair market value of such Investments at the time of such
designation and (iii) the original fair market value of such Investments at the
time they were made. Such designation will only be permitted if such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary.
 
     Any such designation by the Board of Directors shall be evidenced to the
Trustee by filing with the Trustee a certified copy of the board resolution
giving effect to such designation and an officers' certificate certifying that
such designation complied with the foregoing conditions. If, at any time, any
Unrestricted Subsidiary would fail to meet the definition of an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of the Indenture and any Indebtedness of such Subsidiary shall be
deemed to be incurred by a Restricted Subsidiary of the Company as of such date
(and, if such Indebtedness is not permitted to be incurred as of such date under
the covenant described under the caption "-- Incurrence of Indebtedness and
Issuance of Preferred Stock," the Issuers shall be in default of such covenant).
The Board of Directors may at any time designate any Unrestricted Subsidiary to
be a Restricted Subsidiary; provided that such designation shall be deemed to be
an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any
outstanding Indebtedness of such Unrestricted Subsidiary and such designation
shall only be permitted if (i) such Indebtedness is permitted under the covenant
described under the caption "-- Certain Covenants -- Incurrence of Indebtedness
and Issuance of Preferred Stock," calculated on a pro forma basis as if such
designation had occurred at the beginning of the four-quarter reference period,
and (ii) no Default or Event of Default would be in existence following such
designation.
 
  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt) and that the Company will not permit any
of its Restricted Subsidiaries to issue any shares of preferred stock (other
than to the Company or to another Restricted Subsidiary); provided, however,
that the Company and its Restricted Subsidiaries may incur Indebtedness
(including Acquired Debt) and the Company's Restricted Subsidiaries may issue
preferred stock if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such preferred stock is issued would have been at
least 2.0 to 1, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred or the preferred stock had been issued at the beginning of
such four-quarter period.
 
                                       62
<PAGE>   68
 
     The provisions of the first paragraph of this covenant will not apply to
the incurrence of any of the following (collectively, "Permitted Debt"):
 
          (i) the incurrence by the Company or its Restricted Subsidiaries of
     Indebtedness under the Credit Facility; in an aggregate amount not to
     exceed at any time outstanding the greater of (a) $45.0 million, less the
     aggregate amount of all Net Proceeds of Asset Sales applied to repay any
     such Indebtedness pursuant to clause (i) of the second paragraph of the
     covenant described above under the caption "-- Asset Sales," and (b) 60% of
     the Company's and its Restricted Subsidiaries' accounts receivable (net of
     reserves), as shown on the Company's most recent consolidated balance
     sheet;
 
          (ii) the incurrence by the Company of Indebtedness represented by the
     Exchange Notes and the Indenture;
 
          (iii) the incurrence by the Company and its Restricted Subsidiaries of
     the Existing Indebtedness;
 
          (iv) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     that was permitted to be incurred by the first paragraph, or by clauses
     (ii) through (ix) of the second paragraph of this covenant;
 
          (v) the incurrence of Indebtedness between or among the Company and
     any of its Wholly Owned Restricted Subsidiaries; provided, however, that
     (a) if the Company is the obligor on such Indebtedness, such Indebtedness
     is expressly subordinated to the prior payment in full of all Obligations
     with respect to the Exchange Notes and (b) any subsequent issuance or
     transfer of Equity Interests that results in any such Indebtedness being
     held by a Person other than the Company or a Wholly Owned Restricted
     Subsidiary, and any sale or other transfer of any such Indebtedness to a
     Person that is not either the Company or a Wholly Owned Restricted
     Subsidiary, shall be deemed, in each case, to constitute an incurrence of
     such Indebtedness by the Company or such Restricted Subsidiary, as the case
     may be;
 
          (vi) the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     fixing or hedging interest rate risk with respect to any floating rate
     Indebtedness that is permitted by the terms of this Indenture to be
     outstanding;
 
          (vii) the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate amount not to
     exceed $10.0 million at any time outstanding;
 
          (viii) the guarantee by the Company or any of its Restricted
     Subsidiaries of Indebtedness that was permitted to be incurred by another
     provision of this covenant; and
 
          (ix) Indebtedness of a Receivables Subsidiary that is not recourse to
     the Company or any of its Restricted Subsidiaries (other than Standard
     Securitization Undertakings) incurred in connection with a Qualified
     Receivables Transaction.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (ix) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item of Indebtedness in any
manner that complies with this covenant and such item of Indebtedness will be
treated as having been incurred pursuant to only one of such clauses or pursuant
to the first paragraph hereof. Accrual of interest, the accretion of accreted
value and the payment of interest in the form of additional Indebtedness will
not be deemed to be an incurrence of Indebtedness for purposes of this covenant.
 
  LIENS
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume
or suffer to exist any Lien securing Indebtedness or trade payables on any asset
now owned or hereafter acquired, or any income or profits therefrom or assign or
convey any right to receive income therefrom, except Permitted Liens.

  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (i)(a) pay dividends or make any
other distributions to the Company or any of its Restricted Subsidiaries (1) on
its Capital Stock or (2) with respect to any other interest or participation in,
or measured by, its profits, or (b) pay any indebtedness owed to the Company or
any of its Restricted Subsidiaries, (ii) make loans or advances to the Company
or any of its Restricted Subsidiaries or (iii) transfer any of its properties or
assets to the Company or any of its Restricted Subsidiaries, except for such
encumbrances or restrictions existing under or by reason of (a) Existing
Indebtedness as in effect on the Closing Date, (b) the Credit Facility as in
effect as of the Closing Date, and any amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings
thereof, provided that such amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacement or refinancings are no more
restrictive with respect to such dividend and other payment restrictions than
those contained in the Credit Facility as in effect on the Closing Date, (c) the
Indenture and the Exchange Notes, (d) applicable law, (e) any instrument
governing Indebtedness or Capital Stock of a 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), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than
the Person, or the property or assets of the Person, so acquired, provided that,
in the case of Indebtedness, such Indebtedness was permitted by the terms of the
Indenture to be incurred, (f) by reason of customary non-assignment provisions
in leases entered into in the ordinary course of business, (g) purchase money
obligations for property acquired in the ordinary course of business that impose
restrictions of the nature described in clause (iii) above on the property so
acquired, (h) Permitted Refinancing Indebtedness, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive than those contained in the agreements governing the
Indebtedness being refinanced, or (i) any Purchase Money Note, or other
Indebtedness or contractual requirements incurred with respect to a Qualified
Receivables Transaction relating to a Receivables Subsidiary.
 
  MERGER, CONSOLIDATION, OR SALE OF ASSETS
 
     The Indenture provides that neither the Company, nor UNICCO Finance, nor
any Guarantor may consolidate or merge with or into (whether or not the Company,
UNICCO Finance or such Guarantor, as the case may be, is the surviving entity),
or sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its properties or assets in one or more related
transactions, to another corporation, Person or entity unless (i) the Company,
UNICCO Finance or such Guarantor, as the case may be, is the surviving entity,
or the entity or the Person formed by or surviving any such consolidation or
merger (if other than the Company, UNICCO Finance or such Guarantor) or to which
such sale, assignment, transfer, lease, conveyance or other disposition shall
have been made is a corporation, business trust or limited liability company
organized or existing under the laws of the United States, any state thereof or
the District of Columbia; (ii) the entity or Person formed by or surviving any
such consolidation or merger (if other than the Company, UNICCO Finance or such
Guarantor) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company, UNICCO Finance or such Guarantor, as the case may
be, under the Exchange Notes or such Guarantor's Guarantee thereof and the
Indenture pursuant to a supplemental indenture in a form reasonably satisfactory
to the Trustee; (iii) immediately after such transaction no Default or Event of
Default exists; and (iv) except in the case of a merger of the Company or a
Guarantor with or into the Company or another Guarantor, the Company, such
Guarantor or the entity or Person formed by or surviving any such consolidation
or merger (if other than the Company or such Guarantor), or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made will, at the time of such transaction and after giving pro forma effect
thereto (including pro forma expense and cost reductions) as if such transaction
had occurred at the beginning of the applicable four-quarter period, be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Fixed Charge Coverage Ratio test set forth in the first paragraph of
 
                                       64
<PAGE>   70
 
the covenant described above under the caption "-- Incurrence of Indebtedness
and Issuance of Preferred Stock."
 
  TRANSACTIONS WITH AFFILIATES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer
or otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless (i) such Affiliate Transaction is on terms that are no less favorable to
the Company or such Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee
(a) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $0.5 million, a
resolution of the Board of Directors set forth in an officers' certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors, if any, and (b) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $4.0 million, an opinion as to the fairness
to the Holders of such Affiliate Transaction from a financial point of view
issued by an accounting, appraisal or investment banking firm of national
standing.
 
     The foregoing provisions will not prohibit: (i) any employment agreement or
other employment or compensation agreement entered into by the Company or any of
its Restricted Subsidiaries in the ordinary course of business; (ii)
transactions between or among the Company and/or its Restricted Subsidiaries
and/or UNICCO Finance; (iii) direct or indirect transactions between the Company
or any of its Restricted Subsidiaries, on the one hand, and Ashmont Insurance
Company Limited or any of its subsidiaries, on the other hand, on terms that are
not materially less favorable to the Company or the applicable Restricted
Subsidiary than those that could have been obtained from an unaffiliated third
party; (iv) the transactions contemplated under "Use of Proceeds;" (v) notes
payable to or receivable from, and leases of real property from, Affiliates (and
payments thereunder) as in effect on the Closing Date, as the same may be
amended, modified, renewed or extended in a manner no less favorable to the
Company and its Restricted Subsidiaries; (vi) any Restricted Payment that is
permitted by the provisions of the Indenture described above under the caption
"-- Restricted Payments;" and (vii) sales of accounts receivable and other
related assets customarily transferred in an asset securitization transaction
involving accounts receivable to a Receivables Subsidiary in a Qualified
Receivables Transaction.
 
  LIMITATION ON OTHER SENIOR SUBORDINATED DEBT
 
     The Indenture provides that neither the Company nor any Restricted
Subsidiary will incur any Indebtedness that is subordinate or junior in right of
payment to any Senior Debt of the Company or such Restricted Subsidiary, as the
case may be, and senior in any respect in right of payment to the Exchange Notes
or such Restricted Subsidiary's Guarantee thereof.
 
  ADDITIONAL SUBSIDIARY GUARANTEES
 
     The Indenture provides that if the Company or any of its Domestic
Restricted Subsidiaries shall acquire or create another Domestic Restricted
Subsidiary after the date of the Indenture, or any Unrestricted Subsidiary shall
cease to be an Unrestricted Subsidiary and shall become a Domestic Restricted
Subsidiary, then such Subsidiary shall execute a guarantee of the Exchange Notes
and deliver an opinion of counsel unless such Subsidiary shall have been
designated a Receivables Subsidiary in accordance with the terms of the
Indenture.
 
  PAYMENTS FOR CONSENT
 
     The Indenture provides that neither the Company nor UNICCO Finance nor any
of the Company's Restricted Subsidiaries will, directly or indirectly, pay or
cause to be paid any consideration, whether by way of
 
                                       65
<PAGE>   71
 
interest, fee or otherwise, to any Holder of any Exchange Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the Indenture or the Exchange Notes unless such consideration is offered to
be paid or is paid to all Holders of the Exchange Notes that consent, waive or
agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or agreement.
 
  REPORTS
 
     The Indenture provides that, whether or not required by the rules and
regulations of the Commission, so long as any Exchange Notes are outstanding,
the Issuers will furnish to the Holders of Exchange Notes, within 15 days after
the required filing date, (i) all quarterly and annual financial information
(excluding the exhibits and financial schedules) that would be required to be
contained in a filing with the Commission on Forms 10-Q and 10-K if the Issuers
were required to file such Forms, including a "Management's Discussion and
Analysis of Financial Condition and Results of Operations" that describes the
financial condition and results of operations of the Issuers and their
consolidated Subsidiaries (showing in reasonable detail, either on the face of
the financial statements or in the footnotes thereto, the consolidated financial
condition and results of operations of the Company, UNICCO Finance and the
Company's Restricted Subsidiaries separate from the financial information and
results of operations of the Unrestricted Subsidiaries of the Company) and, with
respect to the annual information only, a report thereon by the Issuers'
certified independent accountants and (ii) all current reports that would be
required to be filed with the Commission on Form 8-K if the Issuers were
required to file such reports. In addition, whether or not required by the rules
and regulations of the Commission, the Issuers will file a copy of all such
information and reports with the Commission for public availability (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. In addition, the
Issuers and the Company's Restricted Subsidiaries will agree that, for so long
as any Notes remain outstanding, they will furnish to the Holders and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Act.
 
  ACTIVITIES OF UNICCO FINANCE
 
     The Indenture provides that UNICCO Finance may not hold any material
assets, become liable for any material obligations or engage in any significant
business activities; provided, however, that UNICCO Finance may be a co-obligor
or guarantor with respect to, and may pledge its assets to secure, Indebtedness
of which the Company is an obligor.
 
EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on, or
Liquidated Damages, if any, with respect to, the Exchange Notes (whether or not
prohibited by the subordination provisions of the Indenture), (ii) default in
payment when due of the principal of or premium, if any, on the Exchange Notes
(whether or not prohibited by the subordination provisions of the Indenture);
(iii) failure by the Issuers to comply with the provisions described under the
captions "-- Change of Control," "-- Asset Sales," "-- Restricted Payments,"
"-- Incurrence of Indebtedness and Issuance of Preferred Stock" or "-- Merger,
Consolidation or Sale of Assets;" (iv) failure by the Issuers for 60 days after
written notice by the Trustee or the Holders of at least 25% in principal amount
of the then outstanding Exchange Notes to comply with any of their other
agreements in the Indenture or the Exchange Notes; (v) default under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the
Company, UNICCO Finance or any of the Company's Restricted Subsidiaries (or the
payment of which is guaranteed by the Company, UNICCO Finance or any of the
Company's Restricted Subsidiaries), whether such Indebtedness or guarantee now
exists or is created after the Closing Date, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
prior to the expiration of the grace period provided in such Indebtedness on the
date of such default (a "Payment Default") or (b) results in the acceleration of
such Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there
 
                                       66
<PAGE>   72
 
has been a Payment Default or the maturity of which has been so accelerated,
aggregates $5.0 million or more; (vi) failure by the Company, UNICCO Finance or
any of the Company's Restricted Subsidiaries to pay final judgments aggregating
in excess of $2.0 million and either (a) any creditor commences enforcement
proceedings upon any such judgment or (b) such judgments are not paid,
discharged or stayed for a period of 45 days; (vii) except as permitted by the
Indenture, any guarantee of the Exchange Notes shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Restricted Subsidiary, or any Person acting on
behalf of any Restricted Subsidiary, shall deny or disaffirm its obligations
under its guarantee; (viii) the Refinancing shall not have been consummated by
11:59 p.m., New York City time, on the Closing Date; and (ix) certain events of
bankruptcy or insolvency with respect to the Company, UNICCO Finance or any of
the Company's Restricted Subsidiaries.
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Exchange
Notes may declare all the Exchange Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Company, UNICCO
Finance, any Significant Subsidiary or any group of Restricted Subsidiaries of
the Company that, taken together, would constitute a Significant Subsidiary, all
outstanding Exchange Notes will become due and payable without further action or
notice. Holders of the Exchange Notes may not enforce the Indenture or the Notes
except as provided in the Indenture. Subject to certain limitations, Holders of
a majority in principal amount of the then outstanding Exchange Notes may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of the Exchange Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.
 
     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Issuers with
the intention of avoiding payment of the premium that the Issuers would have had
to pay if the Issuers then had elected to redeem the Exchange Notes pursuant to
the optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Exchange Notes. If an Event of Default occurs prior
to October 15, 2002 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Issuers with the intention of avoiding the
prohibition on redemption of the Exchange Notes prior to such date, then the
premium specified in the Indenture shall also become immediately due and payable
to the extent permitted by law upon the acceleration of the Exchange Notes.
 
     The Holders of a majority in aggregate principal amount of the Exchange
Notes then outstanding by notice to the Trustee may on behalf of the Holders of
all of the Exchange Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Exchange Notes.
 
     The Issuers are required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Issuers are required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, TRUSTEES, INCORPORATORS
AND SHAREHOLDERS
 
     No director, officer, employee, trustee, incorporator or shareholder of
either Issuer or any of the Company's Subsidiaries, as such, shall have any
liability for any obligations of the Issuers or such Subsidiary under the
Exchange Notes, any Guarantee thereof, the Indenture or for any claim based on,
in respect of, or by reason of, such obligations or their creation. Each Holder
of Exchange Notes by accepting a Exchange Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Exchange Notes. Such waiver may not be effective to waive liabilities under
the federal securities laws and it is the view of the Commission that such a
waiver is against public policy.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Issuers may, at their option and at any time, elect to have all of
their obligations discharged with respect to the outstanding Exchange Notes
("Legal Defeasance") except for (i) the rights of Holders of outstanding
Exchange Notes to receive payments in respect of the principal of and premium,
interest and Liquidated Damages, if any, on the Exchange Notes when such
payments are due from the trust referred to below, (ii) the Issuers' obligations
with respect to the Exchange Notes concerning issuing temporary Exchange Notes,
registration of Exchange Notes, mutilated, destroyed, lost or stolen Notes and
the maintenance of an office or agency for payment and money for security
payments held in trust, (iii) the rights, powers, trusts, duties and immunities
of the Trustee, and the Issuers' obligations in connection therewith and (iv)
the Legal Defeasance provisions of the Indenture. In addition, the Issuers may,
at their option and at any time, elect to have the obligations of the Issuers
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Exchange Notes. In the event Covenant Defeasance occurs, certain events (not
including non-payment, bankruptcy, receivership, rehabilitation and insolvency
events) described under "Events of Default" will no longer constitute an Event
of Default with respect to the Exchange Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Exchange Notes, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of and premium, interest and Liquidated
Damages, if any, on the outstanding Exchange Notes on the stated maturity or on
the applicable redemption date, as the case may be, and the Issuers must specify
whether the Exchange Notes are being defeased to maturity or to a particular
redemption date; (ii) in the case of Legal Defeasance, the Issuers shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee confirming that (a) the Issuers have received from, or
there has been published by, the Internal Revenue Service a ruling or (b) since
the Closing Date, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of
counsel shall confirm that, the Holders of the outstanding Exchange Notes will
not recognize income, gain or loss for federal income tax purposes as a result
of such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred; (iii) in the case of Covenant
Defeasance, the Issuers shall have delivered to the Trustee an opinion of
counsel in the United States reasonably acceptable to the Trustee confirming
that the Holders of the outstanding Exchange Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (iv) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such
deposit) or insofar as Events of Default from bankruptcy or insolvency events
are concerned, at any time in the period ending on the 91st day after the date
of deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in
a breach or violation of, or constitute a default under any material agreement
or instrument (other than the Indenture) to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Issuers shall have delivered to the Trustee an opinion of
counsel to the effect that after the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally; (vii) the Issuers shall have delivered to the Trustee an officers'
certificate stating that the deposit was not made by the Issuers with the intent
of preferring the Holders of Exchange Notes over the other creditors of the
Issuers with the intent of defeating, hindering, delaying or defrauding
creditors of the Issuers or others; and (viii) the Issuers shall have delivered
to the Trustee an officers' certificate and an opinion of counsel, each stating
that all conditions precedent provided for relating to the Legal Defeasance or
the Covenant Defeasance have been complied with.

TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange the Exchange Notes in accordance with and
subject to the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Issuers may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Issuers are not required to transfer or
exchange any Exchange Note selected for redemption. Also, the Issuers are not
required to transfer or exchange any Exchange Note for a period of 15 days
before a selection of Exchange Notes to be redeemed.
 
     The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next two succeeding paragraphs, the Indenture,
the Exchange Notes and the Guarantees thereof may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of
the Exchange Notes then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Exchange Notes), and any existing default or compliance with any provision
of the Indenture, the Exchange Notes or the Guarantees thereof may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding Exchange Notes (including consents obtained in connection with a
tender offer or exchange offer for Exchange Notes).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Exchange Notes held by a non-consenting Holder): (i) reduce
the principal amount of Exchange Notes whose Holders must consent to an
amendment, supplement or waiver, (ii) reduce the principal of or change the
fixed maturity of any Exchange Note or alter the provisions with respect to the
redemption of the Exchange Notes (other than provisions relating to the
covenants described above under the caption "-- Repurchase at the Option of
Holders"), (iii) reduce the rate of or change the time for payment of interest
on any Note, (iv) waive a Default or Event of Default in the payment of
principal of or premium, interest or Liquidated Damages, if any, on the Exchange
Notes (except a rescission of acceleration of the Exchange Notes by the Holders
of at least a majority in aggregate principal amount of the Notes and a waiver
of the payment default that resulted from such acceleration), (v) make any
Exchange Note payable in money other than that stated in the Exchange Notes,
(vi) make any change in the provisions of the Indenture relating to waivers of
past Defaults or the rights of Holders of Exchange Notes to receive payments of
principal of or premium, interest or Liquidated Damages, if any, on the Exchange
Notes, (vii) waive a redemption payment with respect to any Exchange Note (other
than a payment required by one of the covenants described above under the
caption "-- Repurchase at the Option of Holders"), (ix) release any Restricted
Subsidiary from its Guarantee of the Exchange Notes except as provided in the
Indenture or (ix) make any change in the foregoing amendment and waiver
provisions. In addition, any amendment to the provisions of Article 10 of the
Indenture (which relate to subordination) (a) will require the consent of all
holders of Senior Debt if such amendment would adversely affect the rights of
holders of Senior Debt and (b) will require the consent of the Holders of at
least 75% in aggregate principal amount of the Exchange Notes then outstanding
if such amendment would adversely affect the rights of Holders of Exchange
Notes.
 
     Notwithstanding the foregoing, without the consent of any Holder of
Exchange Notes, the Issuers, the Company's Restricted Subsidiaries and the
Trustee may amend or supplement the Indenture, the Exchange Notes or any
Guarantee thereof to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Exchange Notes in addition to or in place of certificated
Exchange Notes, to provide for the assumption of the Company's, UNICCO Finance's
or any Restricted Subsidiary's obligations to Holders of Exchange Notes in the
case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of Exchange Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act.

CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Issuers, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.
 
     The Holders of a majority in principal amount of the then outstanding
Exchange Notes will have 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 in case an Event of
Default shall occur (which shall not be 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 Exchange Notes, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.
 
ADDITIONAL INFORMATION
 
     Anyone who receives this Prospectus may obtain a copy of form of the
Indenture and Registration Rights Agreement without charge by writing to UNICCO
Service Company, Four Copley Place, Boston, Massachusetts 02116, Attention:
George A. Keches, Chief Financial Officer.
 
BOOK-ENTRY, DELIVERY AND FORM
 
     The certificates representing the Exchange Notes will be issued in fully
registered form. Except as described in the next paragraph, the Exchange Notes
initially will be represented by a single, permanent global Exchange Note, in
definitive, fully registered form without interest coupons (the "Global Exchange
Note") and will be deposited with the Trustee as custodian for DTC and
registered in the name of Cede & Co. or such other nominee as DTC may designate.
The Global Exchange Note (and any Exchange Notes issued in exchange therefor)
will be subject to certain restrictions on transfer set forth therein and in the
Indenture and will bear the respective legends regarding such restrictions.
 
     Holders of Exchange Notes who elect to take physical delivery of their
certificates instead of holding their interest through the Global Exchange Note
(collectively referred to herein as the "Non-Global Holders") will be issued in
registered form a certificated Exchange Note ("Certificate Exchange Note"). Upon
the transfer of any Certificated Exchange Note initially issued to a Non-Global
Holder, such Certificated Exchange Note will, unless the transferee requests
otherwise or the Global Exchange Note has previously been exchanged in whole for
Certificated Exchange Notes, be exchanged for an interest in the Global Exchange
Note.
 
     The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the Initial
Purchaser), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only thorough the Depositary's
Participants or the Depositary's Indirect Participants.
 
     The Issuers expect that, pursuant to procedures established by the
Depositary, (i) upon deposit of the Global Exchange Notes, the Depositary will
credit the accounts of Participants designated by the Initial Purchaser with
portions of the principal amount of the Global Exchange Notes and (ii) ownership
of the Exchange Notes evidenced by the Global Exchange Notes will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depositary (with respect to the interests of the Depositary's
Participants), the Depositary's Participants and the Depositary's Indirect
Participants.
 
                                       70
<PAGE>   76
 
Prospective purchasers are advised that the laws of some states require that
certain persons take physical delivery in definitive form of securities that
they own. Consequently, the ability to transfer Exchange Notes evidenced by the
Global Exchange Notes will be limited to such extent. For certain other
restrictions on the transferability of the Exchange Notes, see "Notice to
Investors."
 
     So long as the Global Exchange Note Holder is the registered owner of any
Notes, the Global Exchange Note Holder will be considered the sole Holder under
the Indenture of any Exchange Notes evidenced by the Global Exchange Notes.
Beneficial owners of Notes evidenced by the Global Exchange Notes will not be
considered the owners or Holders thereof under the Indenture for any purpose,
including with respect to the giving of any directions, instructions or
approvals to the Trustee thereunder. Neither the Issuers nor the Trustee will
have any responsibility or liability for any aspect of the records of the
Depositary or for maintaining, supervising or reviewing any records of the
Depositary relating to the Exchange Notes.
 
     Payments in respect of the principal of and premium, interest and
Liquidated Damages, if any, on any Exchange Notes registered in the name of the
Global Exchange Note Holder on the applicable record date will be payable by the
Trustee to or at the direction of the Global Exchange Note Holder in its
capacity as the registered Holder under the Indenture. Under the terms of the
Indenture, the Issuers and the Trustee may treat the persons in whose names
Exchange Notes, including the Global Exchange Notes, are registered as the
owners thereof for the purpose of receiving such payments. Consequently, neither
the Issuers nor the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Exchange Notes. The Issuers
believe, however, that it is currently the policy of the Depositary to
immediately credit the accounts of the relevant Participants with such payments,
in amounts proportionate to their respective holdings of beneficial interests in
the relevant security as shown on the records of the Depositary. Payments by the
Depositary's Participants and the Depositary's Indirect Participants to the
beneficial owners of Exchange Notes will be governed by standing instructions
and customary practice and will be the responsibility of the Depositary's
Participants or the Depositary's Indirect Participants.
 
  ADDITIONAL INFORMATION CONCERNING EUROCLEAR AND CEDEL BANK
 
     Euroclear and Cedel Bank hold securities for participating organizations
and facilitate the clearance and settlement of securities transactions between
their respective participants through electronic book-entry changes in accounts
of such participants. Euroclear and Cedel Bank provide to their participants,
among other things, services for safekeeping, administration, clearance and
settlement of internationally traded securities and securities lending and
borrowing. Euroclear and Cedel Bank interface with domestic securities markets.
Euroclear and Cedel Bank participants are financial institutions such as
underwriters, securities brokers and dealers, banks, trust companies and certain
other organizations. Indirect access to Euroclear and Cedel Bank is also
available to others such as banks, brokers, dealers and trust companies that
clear through or maintain a custodian relationship with a Euroclear or Cedel
Bank participant, either directly or indirectly. The Issuers will have no direct
control over the clearance and settlement of transactions through Euroclear or
Cedel Bank.
 
     When beneficial interests are to be transferred from the account of a
Participant (other than Morgan Guaranty Trust Company of New York and Citibank,
N.A., as depositaries for Euroclear and Cedel Bank, respectively) to the account
of a Euroclear participant or a Cedel Bank participant, the purchaser must send
instructions to Euroclear or Cedel Bank through a participant at least one
business day prior to settlement. Euroclear or Cedel Bank, as the case may be,
will instruct Morgan Guaranty Trust Company of New York or Citibank, N.A. to
receive the beneficial interests against payment. Payment will include interest
attributable to the beneficial interest from and including the last payment date
to and excluding the settlement date, on the basis of a calendar year consisting
of twelve 30-day calendar months. For transactions settling on the 31st day of
the month, payment will include interest accrued to and excluding the first day
of the following month. Payment will then be made by Morgan Guaranty Trust
Company of New York or Citibank, N.A., as the case may be, to the Participant's
account against delivery of the beneficial interests. After settlement has been
completed, the beneficial interests will be credited to the respective clearing
systems and by the clearing system, in accordance with its usual procedures, to
the Euroclear participants' or Cedel Bank participants' account. Credit for the
beneficial interests will appear on the next business day (European time) and
the cash debit will be back-valued to, and interest attributable to the
beneficial interests will accrue from, the value
 
                                       71
<PAGE>   77
 
date (which would be the preceding business day when settlement occurs in New
York). If settlement is not completed on the intended value date (i.e., the
trade fails), the Euroclear or Cedel Bank cash debit will instead be valued as
of the actual settlement date.
 
     Euroclear participants and Cedel Bank participants will need to make
available to the respective clearing systems the funds necessary to process
same-day funds settlement. The most direct means of doing so is to preposition
funds for settlement, either from cash on hand or existing lines of credit, as
they would for any settlement occurring within Euroclear or Cedel Bank. Under
this approach, they may take on credit exposure to Euroclear or Cedel Bank until
the beneficial interests are credited to their accounts one day later. Finally,
day traders that use Euroclear or Cedel Bank and that purchase beneficial
interests from Participants for credit to Euroclear participants or Cedel Bank
participants should note that these trades would automatically fall on the sale
side unless affirmative action were taken to avoid these potential problems.
 
     Due to time zone differences in their favor, Euroclear participants and
Cedel Bank participants may employ their customary procedures for transactions
in which beneficial interests are to be transferred by the respective clearing
system, through Morgan Guaranty Trust Company of New York or Citibank, N.A., to
another Participant. The seller must send instructions to Euroclear or Cedel
Bank through a participant at least one business day prior to settlement. In
these cases, Euroclear or Cedel Bank will instruct Morgan Guaranty Trust Company
of New York or Citibank, N.A., as the case may be, to credit the beneficial
interests to the Participant's account against payment. Payment will include
interest attributable to the beneficial interest from and including the last
payment date to and excluding the settlement date on the basis of a calendar
year consisting of twelve 30-day calendar months. For transactions settling on
the 31st day of the month, payment will include interest accrued to and
excluding the first day of the following month. The payment will then be
reflected in the account of the Euroclear participant or Cedel Bank participant
the following business day, and receipt of the cash proceeds in the Euroclear or
Cedel Bank participant's account will be back-valued to the value date (which
would be the preceding business day, when settlement occurs in New York). If the
Euroclear participant or Cedel Bank participant has a line of credit with its
representative clearing system and elects to draw on such line of credit in
anticipation of receipt of the sale proceeds in its account, the back-valuation
may substantially reduce or offset any overdraft charges incurred over that one-
day period. If settlement is not completed on the intended value date (i.e., if
trade fails), receipt of the cash proceeds in the Euroclear or Cedel Bank
participant's account would instead be valued as of the actual settlement date.
 
  CERTIFICATED SECURITIES
 
     Subject to certain conditions, any person having a beneficial interest in a
Global Exchange Note may, upon request, exchange such beneficial interest for
Exchange Notes in the form of Certificated Securities. Upon any such issuance,
the Trustee is required to register such Certificated Securities in the name of,
and cause the same to be delivered to, such person or persons (or the nominee of
any thereof). All such certificated Exchange Notes would be subject to the
legend requirements described herein under "Notice to Investors." In addition,
if (i) the Issuers notify the Trustee in writing that the Depositary is no
longer willing or able to act as a depositary and the Issuers are unable to
locate a qualified successor within 90 days or (ii) the Issuers, at their
option, notify the Trustee in writing that they elect to cause the issuance of
Exchange Notes in the form of Certificated Securities under the Indenture, then,
upon surrender by the Global Exchange Note Holder of the Global Exchange Notes,
Exchange Notes in such form will be issued to each person that the Global
Exchange Note Holder and the Depositary identify as being the beneficial owner
of the related Exchange Notes.
 
     Neither the Issuers nor the Trustee will be liable for any delay by the
Global Exchange Note Holder or the Depositary in identifying the beneficial
owners of Exchange Notes and the Issuers and the Trustee may conclusively rely
on, and will be protected in relying on, instructions from the Global Exchange
Note Holder or the Depositary for all purposes.
 
                                       72
<PAGE>   78
 
  SAME-DAY SETTLEMENT AND PAYMENT
 
     The Indenture will require that payments in respect of the Exchange Notes
represented by the Global Exchange Notes (including principal, premium, interest
and Liquidated Damages, if any) be made by wire transfer of immediately
available funds to the accounts specified by the Global Exchange Note Holder.
With respect to Certificated Securities, the Issuers will make all payments of
principal, premium, interest and Liquidated Damages, if any, by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each such Holder's
registered address.
 
     The Exchange Notes represented by the Global Exchange Notes are expected to
be eligible to trade in the PORTAL market and to trade in the Depositary's
Same-Day Funds Settlement System, and any permitted secondary market trading
activity in such Exchange Notes will, therefore, be required by the Depositary
to be settled in immediately available funds. The Issuers expect that secondary
trading in the Certificated Securities will also be settled in immediately
available funds, although such settlement will not be within the Issuers'
control.
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     The Issuers, the Company's Restricted Subsidiaries and the Initial
Purchaser entered into the Registration Rights Agreement on the Closing Date.
Pursuant to the Registration Rights Agreement, the Issuers agreed to file with
the Commission the Exchange Offer Registration Statement on the appropriate form
under the Securities Act with respect to the Exchange Notes. Upon the
effectiveness of the Exchange Offer Registration Statement, the Issuers will
offer to the Holders of Transfer Restricted Securities pursuant to the Exchange
Offer who are able to make certain representations the opportunity to exchange
their Transfer Restricted Securities for Exchange Notes. If (i) the Issuers are
not required to file the Exchange Offer Registration Statement or permitted to
consummate the Exchange Offer because the Exchange Offer is not permitted by
applicable law or Commission policy or (ii) any Holder of Transfer Restricted
Securities notifies the Company prior to the 20th day following consummation of
the Exchange Offer that (a) it is prohibited by law or Commission policy from
participating in the Exchange Offer or (b) that it may not resell the Exchange
Notes acquired by it in the Exchange Offer to the public without delivering a
prospectus and the prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales or (c) that it is a
broker-dealer and owns Series A Notes acquired directly from the Issuers or an
affiliate of the Issuers, the Issuers will file with the Commission a Shelf
Registration Statement to cover resales of the Series A Notes by the Holders
thereof who satisfy certain conditions relating to the provision of information
in connection with the Shelf Registration Statement. The Issuers will use their
reasonable best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the Commission. For purposes of
the foregoing, "Transfer Restricted Securities" means each Series A Note until
(i) the date on which such Series A Note has been exchanged by a person other
than a broker-dealer for an Exchange Note in the Exchange Offer, (ii) following
the exchange by a broker-dealer in the Exchange Offer of a Series A Note for an
Exchange Note, the date on which such Exchange Note is sold to a purchaser who
receives from such broker-dealer on or prior to the date of such sale a copy of
the prospectus contained in the Exchange Offer Registration Statement, (iii) the
date on which such Series A Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Series A Note is resold to the public
pursuant to Rule 144 under the Act.
 
     The Registration Rights Agreement provides that (i) the Issuers will file
an Exchange Offer Registration Statement with the Commission on or prior to 45
days after the Closing Date, (ii) the Issuers will use their best efforts to
have the Exchange Offer Registration Statement declared effective by the
Commission on or prior to 120 days after the Closing Date, (iii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Issuers will commence the Exchange Offer and use their best efforts to
issue, on or prior to 30 business days after the date on which the Exchange
Offer Registration Statement was declared effective by the Commission, Exchange
Notes in exchange for all Series A Notes tendered prior thereto in the Exchange
Offer and (iv) if obligated to file the Shelf Registration Statement, the
Issuers will use their best efforts to file the Shelf Registration Statement
with the Commission on or prior to 45 days after
 
                                       73
<PAGE>   79
 
such filing obligation arises and to cause the Shelf Registration to be declared
effective by the Commission on or prior to 120 days after such obligation
arises. If (a) the Issuers fail to file any of the Registration Statements
required by the Registration Rights Agreement on or before the date specified
for such filing, (b) any of such Registration Statements is not declared
effective by the Commission on or prior to the date specified for such
effectiveness, (c) the Issuers fail to consummate the Exchange Offer within 30
business days of the effective date of the Exchange Offer Registration Statement
or (d) the Shelf Registration Statement or the Exchange Offer Registration
Statement is declared effective but thereafter ceases to be effective or usable
in connection with resales of Transfer Restricted Securities during the periods
specified in the Registration Rights Agreement (each such event referred to in
clauses (a) through (d) above a "Registration Default"), then the Issuers will
pay Liquidated Damages to each Holder of Notes affected thereby, with respect to
the first 90-day period immediately following the occurrence of the first
Registration Default, in an amount equal to $.05 per week per $1,000 principal
amount of Series A Notes held by such Holder. The amount of the Liquidated
Damages will increase by an additional $.05 per week per $1,000 principal amount
of Series A Notes with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $.50 per week per $1,000 principal amount of Series A Notes. All
accrued Liquidated Damages will be paid by the Issuers on each Damages Payment
Date to the Global Note Holder by wire transfer of immediately available funds
or by federal funds check and to Holders of Certificated Securities by wire
transfer to the accounts specified by them or by mailing checks to their
registered addresses if no such accounts have been specified. Following the cure
of all Registration Defaults, the accrual of Liquidated Damages will cease.
 
     Holders of Series A Notes will be required to make certain representations
to the Issuers (as described herein) in order to participate in the Exchange
Offer and will be required to deliver information to be used in connection with
the Shelf Registration Statement and to provide comments on the Shelf
Registration Statement within the time periods set forth in the Registration
Rights Agreement in order to have their Series A Notes included in the Shelf
Registration Statement and benefit from the provisions regarding Liquidated
Damages set forth above.

                              PLAN OF DISTRIBUTION
 
     Each Participating Broker-Dealer that receives Exchange Notes for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
Prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer in connection with resales of Exchange Notes
received in exchange for Series A Notes where such Series A Notes were acquired
as a result of market-making activities or other trading activities. The Company
has agreed that it will make this Prospectus, as amended or supplemented,
available to any Participating Broker-Dealer for use in connection with any such
resale, and Participating Broker-Dealers shall be authorized to deliver this
Prospectus in connection with the sale or transfer of the Exchange Notes. In
addition, until             , 1998 (90 days after the date of this Prospectus),
all dealers effecting transactions in the Exchange Notes may be required to
deliver a prospectus.
 
     The Issuers will not receive any proceeds from any sales of the Exchange
Notes by Participating Broker-Dealers. Exchange Notes received by Participating
Broker-Dealers for their own account pursuant to the Exchange Offer may be sold
from time to time, in one or more transactions in the over-the-counter market,
in negotiated transactions, through the writing of options on the Exchange Notes
or a combination of such methods of resale, at market prices prevailing at the
time of resale, at prices related to such prevailing market prices or at
negotiated prices. Any such resale may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of
commissions or concessions from any such Participating Broker-Dealer that
resells the Exchange Notes that were received by it for its own account pursuant
to the Exchange Offer. Any broker or dealer that participates in a distribution
of such Exchange Notes may be deemed to be an "underwriter" within the meaning
of the Securities Act and any profit on any such resale of Exchange Notes and
any commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that, by acknowledging that it will deliver and by delivering a
prospectus, a Participating Broker-Dealer will not be deemed to admit that is an
"underwriter" within the meaning of the Securities Act.
 
     The Issuers will promptly send additional copies of this Prospectus and any
amendment or supplement of this Prospectus to any Participating Broker-Dealer
that requests such documents in the Letter of Transmittal. See "The Exchange
Offer."

                CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS
                         FOR NON-UNITED STATES HOLDERS
 
     The following is a general discussion of certain United States federal
income and estate tax consequences of the acquisition, ownership and disposition
of Notes by an initial beneficial owner of Notes that, for United States federal
income tax purposes, is not a "United States person" (a "Non-United States
Holder"). This discussion is based upon the United States federal tax law now in
effect, which is subject to change, possibly retroactively. For purposes of this
discussion, a "United States person" means a citizen or resident of the United
States, a corporation, partnership or other entity created or organized in the
United States or under the laws of the United States or of any political
subdivision thereof, an estate whose income is includible in gross income for
United States federal income tax purposes regardless of its source or a trust,
if a U.S. court is able to exercise primary supervision over the administration
of the trust and one or more U.S. persons have the authority to control all
substantial decisions of the trust. The tax treatment of the holders of the
Notes may vary depending upon their particular situations. U.S. persons
acquiring the Notes are subject to different rules than those discussed below.
In addition, certain other holders (including insurance companies, tax exempt
organizations, financial institutions and broker-dealers) may be subject to
special rules not discussed below. Prospective investors are urged to consult
their tax advisors regarding the United States federal tax consequences of
acquiring, holding and disposing of Notes, as well as any tax consequences that
may arise under the laws of any foreign, state, local or other taxing
jurisdiction. New final regulations dealing with withholding tax on income paid
to foreign persons and related matters (the "New Withholding Regulations") were
recently issued by the Treasury Department. In general, the New Withholding
Regulations do not significantly alter the substantive withholding and
information reporting requirements, but unify current certification procedures
and forms and clarify reliance standards. The New Withholding Regulations will
generally be effective for payments made after December 31, 1998, subject to
certain transition rules. Accordingly, payments made on or before December 31,
1998 will continue to be subject to the regulations that existed before the New
Withholding Regulations were issued. THE NEW WITHHOLDING REGULATIONS ARE QUITE
COMPLEX. THE NON-UNITED STATES HOLDERS ARE STRONGLY URGED TO CONSULT THEIR OWN
TAX ADVISORS WITH RESPECT TO THE NEW WITHHOLDING REGULATIONS.
 
INTEREST
 
     Interest paid by the Company to a Non-United States Holder will not be
subject to United States federal income or withholding tax if such interest is
not effectively connected with the conduct of a trade or business within the
United States by such Non-United States Holder and such Non-United States Holder
(i) does not actually or constructively own 10% or more of the total combined
voting power of all classes of stock of the Company; (ii) is not a controlled
foreign corporation with respect to which the Company is a "related person"
within the meaning of the United States Internal Revenue Code of 1986, as
amended (the "Code"), and (iii) certifies, under penalties of perjury, that such
holder is not a United States person and provides such holder's name and
address. Under the New Withholding Regulations, the statement is required to be
made on Form W-8 and provided prior to payment. For a Non-United States Holder
who is claiming the benefits of a tax treaty, the New Withholding Regulations
may require such holder to obtain a U.S. taxpayer identification number and to
provide certain documentary evidence issued by foreign governmental authorities
to prove residence in the foreign country. Certain special procedures are
provided in the New Withholding Regulations for payments through qualified
intermediaries.
 
GAIN ON DISPOSITION
 
     A Non-United States Holder will generally not be subject to United States
federal income tax on gain recognized on a sale, redemption or other disposition
of a Note unless (i) the gain is effectively connected with the conduct of a
trade or business within the United States by the Non-United States Holder or
(ii) in the case of a Non-United States Holder who is a nonresident alien
individual and holds the Note as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year and certain other
requirements are met.
 
                                       84
<PAGE>   90
 
FEDERAL ESTATE TAXES
 
     If interest on the Notes is exempt from withholding of United States
federal income tax under the rules described above, the Notes will not be
included in the estate of a deceased Non-United States Holder for United States
federal estate tax purposes.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     For payments made on or before December 31, 1998, the Company will, where
required, report to the holders of Notes and the Internal Revenue Service the
amount of any interest paid on the Notes in each calendar year and the amounts
of tax withheld, if any, with respect to such payments.
 
     In the case of payments of interest to Non-United States Holders, temporary
Treasury regulations provide that the 31% backup withholding tax and certain
information reporting will not apply to such payments with respect to which
either the requisite certification, as described above, has been received or an
exemption has otherwise been established; provided that neither the Company nor
its payment agent has actual knowledge that the holder is a United States person
or that the conditions of any other exemption are not in fact satisfied. Under
temporary Treasury regulations, these information reporting and backup
withholding requirements will apply, however, to the gross proceeds paid to a
Non-United States Holder on the disposition of the Notes by or through a United
States office of a United States or foreign broker, unless the holder certifies
to the broker under penalties of perjury as to its name, address and status as a
foreign person or the holder otherwise establishes an exemption. Information
reporting requirements, but not backup withholding, will also apply to a payment
of the proceeds of a disposition of the Notes by or through a foreign office of
a United States broker or foreign brokers with certain types of relationships to
the United States unless such broker has documentary evidence in its file that
the holder of the Notes is not a United States person, and such broker has no
actual knowledge to the contrary, or the holder establishes an exception.
Neither information reporting nor backup withholding generally will apply to a
payment of the proceeds of a disposition of the Notes by or through a foreign
office of a foreign broker not subject to the preceding sentence.
 
     For payments made after December 31, 1998, the New Withholding Regulations
provide that to the extent a Non-United States Holder certifies on Form W-8 (or
a permitted substitute form) as to such holder's status as a foreign person, the
backup withholding provisions and the information reporting provisions will
generally not apply. If a Non-United States Holder fails to provide such
certification, such holder may be subject to certain information reporting and
the 31% backup withholding tax.
 
     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be refunded or credited against the Non-United
States Holder's United States federal income tax liability, provided that the
required information is furnished to the Internal Revenue Service.
 
                                 LEGAL MATTERS
 
     Certain legal matters will be passed upon on behalf of the Company by
Posternak, Blankstein & Lund, L.L.P., Boston, Massachusetts.
 
                                    EXPERTS
 
     The financial statements of the Company as of June 29, 1997 and June 30,
1996 and for each of the two years then ended and the statements of income and
of cash flows of the Allied Facility Services Business for the years ended June
28, 1996 and June 30, 1995 included in this Prospectus have been so included in
reliance on the report of Price Waterhouse LLP, independent accountants, given
on the authority of said firm as experts in auditing and accounting.
 
     The statements of income, stockholders' equity and cash flows of the
Company for the year ended June 25, 1995 included in this Prospectus and
elsewhere in the Registration Statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their report with respect
thereto, and are included herein in reliance upon the authority of said firm as
experts in giving said report.

     On March 14, 1997, the Company's management retained Price Waterhouse LLP
as its independent accountants. The reports of the Company's former accountants
on the Company's financial statements did not contain any adverse opinion or
disclaimer of opinion and were not modified as to uncertainty, audit scope or
accounting principles. There were no disagreements with the former accountants
on any matter of accounting principles or practices, financial statement
disclosure or auditing scope or procedure with respect to the Company's
financial statements, which, if not resolved to the former accountants'
satisfaction, would have caused them to make reference to the subject matter of
the disagreement in connection with their reports. Prior to retaining Price
Waterhouse LLP, the Company had not consulted with such firm regarding
accounting principles or practices.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Trustees and the Board of Directors
and Shareholders of UNICCO Service Company and
USC, Inc.
 
     In our opinion, the accompanying combined consolidated balance sheet and
the related combined consolidated statements of income, of shareholders' equity
and of cash flows present fairly, in all material respects, the financial
position of UNICCO Service Company and USC, Inc. and their subsidiaries (the
"Company") at June 29, 1997 and June 30, 1996, and the results of their
operations and their cash flows for the years then ended 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.

the year ended June 25, 1995. 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 audit.
 
     We conducted our audit 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 audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of UNICCO Service Company as of
June 25, 1995, and the results of its operations and cash flows for the year
ended June 25, 1995, in conformity with generally accepted accounting
principles.

              NOTES TO COMBINED CONSOLIDATED FINANCIAL STATEMENTS
 
1.  OPERATIONS
 
     These combined consolidated financial statements include the consolidated
accounts of UNICCO Service Company and subsidiary ("UNICCO"), and USC, Inc. and
subsidiaries ("USC"), hereafter referred to collectively as the "Group", which
are owned and controlled by common shareholders. USC owns all of the outstanding
common stock of UNICCO Government Services, Inc. and UNICCO Security Services,
Inc. and 21% of the outstanding common stock of UNICCO Facility Services Canada
Company ("UFSCC"). UNICCO owns the remaining 79% of the outstanding common stock
of UFSCC. The Group provides integrated facilities services, including
industrial and mechanical engineering, plant operations, custodial and
maintenance services, administrative services and security. The Group's
customers include commercial, industrial and financial institutions, educational
and healthcare facilities, and state and federal government agencies.
 
2.  ACQUISITION
 
     On June 28, 1996: (1) UNICCO acquired certain assets and the business, as
defined, of certain Allied Facility Services ("AFS") operations engaged in
janitorial, office, facility management and mechanical maintenance services,
primarily in the United States; (2) USC acquired all of the common stock and the
business of certain AFS operations engaged primarily in (a) building security
and (b) facility services to agencies of the federal government; and (3) UFSCC
acquired the assets and the business of certain AFS operations engaged in
janitorial, office facility management and mechanical maintenance services in
Canada. The aggregate purchase price of approximately $62 million was financed
in part by senior bank debt, subordinated debt and a $12 million note payable to
the seller (see Note 4). The acquisition was accounted for as a purchase, and
accordingly, the operations of the acquired businesses are included in the
accompanying financial statements from the date of acquisition. The operations
of the acquired businesses did not have a material effect on the Group's
combined consolidated statement of income for the year ended June 30, 1996.
 
     The allocation of the purchase price of the acquired businesses, including
acquisition related costs of approximately $946,000, is as follows:

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Unaudited Interim Financial Information
 
     The interim financial data as of September 28, 1997 and for the three month
periods ended September 28, 1997 and September 29, 1996 is unaudited; however,
in the opinion of the Company, the interim data includes all adjustments,
consisting only of normal recurring adjustments, necessary for a fair statement
of the financial position and the results of operations as of and for the
interim periods.
 
  Principles of Combination and Consolidation
 
     The accompanying combined consolidated financial statements include the
accounts of the entities referred to in Note 1. All significant transactions
between the entities in the Group have been eliminated in combination and
consolidation.
 
  Accounting Records
 
     UNICCO is on the cash basis of accounting for tax reporting purposes. USC,
Inc. and subsidiaries are on the accrual basis of accounting for tax reporting
purposes. All adjustments have been made to the financial statements to reflect
the accrual basis of accounting.
 
  Fiscal Year
 
     The Group is on a 52/53 week fiscal year ending on the close of business on
the last Sunday of June. The fiscal year end 1996 was a fifty-three week year.
 
  Cash and Cash Equivalents
 
     The Group considers all highly liquid investments with remaining maturities
of three months or less at the time of acquisition to be cash equivalents.
 
  Depreciation and Amortization
 
     The Group provides for depreciation and amortization by charges to
operations in amounts that allocate the cost of property and equipment and
leasehold improvements over their estimated useful lives using the declining
balance and straight-line methods as follows:

  Intangible Assets
 
     Intangible assets consist primarily of acquired contract rights, favorable
lease arrangements, noncompete agreements and goodwill, representing the excess
of the purchase price over the fair value of the net assets acquired in each
acquisition accounted for as purchase. Acquired contract rights are amortized on
a straight-line basis over estimated useful lives ranging from seven to 15
years. These lives represent the estimated average lives of the contracts
acquired and are based generally on the historical experience of the individual
businesses and contracts acquired. Capitalized noncompete agreements are
amortized over three years, representing the contractual noncompete period.
Goodwill is amortized on a straight-line basis over an estimated life of 15
years. Intangible assets (rounded to the nearest thousand) consist of the
following at June 29, 1997 and June 30, 1996:

</TABLE>
 
  Impairment
 
     The Group has adopted Statement of Financial Accounting Standards No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of." In accordance with this Statement, the Group reviews long-lived
assets and related goodwill for impairment whenever events or changes in
circumstances indicate that the carrying amounts of such assets may not be fully
recoverable.
 
  Other Assets
 
     Other assets consist principally of deferred financing costs, which are
amortized over the repayment term of the respective debt.
 
  Revenue Recognition
 
     Service revenues are generated primarily by efforts expended on cost-plus
fixed-fee, fixed price and time and material contracts. Revenue from cost-plus
fixed-fee contracts is recognized on the basis of direct and indirect expenses
incurred plus the allocable portion of the fixed fee. Revenues on fixed price
contracts are recognized based on the monthly amount as stipulated in the
contract and the performance of services. Revenues under time and material
contracts are recorded at the contracted rates as labor efforts are expended and
other direct costs are incurred. Losses, if any, are provided for at the time
that management determines that costs, including estimated costs to complete,
exceed contract revenue.
 
  Financial Instruments
 
     The Group's financial instruments consist of cash, cash equivalents,
receivables, accounts payable and debt instruments. The estimated fair values of
the Group's cash, cash equivalents, receivables, accounts payable and fixed-rate
debt instruments approximate their carrying value.
 
  Income Taxes
 
     Income taxes for financial reporting purposes are recorded in accordance
with Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (FAS 109). The asset and liability approach underlying FAS 109 requires
the recognition of deferred tax liabilities and assets for the expected future
tax

       NOTES TO COMBINED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
consequences of temporary differences between the carrying amounts and tax bases
of the Group's assets and liabilities.
 
  Foreign Currency Translation
 
     In accordance with Statement of Financial Accounting Standards No. 52,
"Foreign Currency Translation," the financial statements of UFSCC are translated
into U.S. dollars as follows: assets and liabilities at year-end exchange rates;
income, expenses and cash flows at average exchange rates; and shareholders'
equity at historical exchange rates. The resulting translation adjustment is
recorded as a component of shareholders' equity.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts and disclosures reported in the accompanying
combined consolidated financial statements. Actual amounts could differ from
those estimates.
 
  Concentration of Credit Risk
 
     Concentrations of credit risk with respect to accounts receivable and
unbilled receivables are limited because a large number of North American
customers make up the Group's customer base, thus spreading trade credit risk.
In addition, the Group performs ongoing evaluations of customers' financial
position. The Group does not require collateral and maintains reserves for
potential uncollectible amounts which, in the aggregate, have not exceeded
management expectations.
 
  Reclassifications
 
     Certain amounts in the prior year financial statements have been
reclassified to conform with the current year's presentation.
 
4.  DEBT
 
     Subsequent to September 28, 1997 the Company consummated a refinancing
transaction in which it paid in full all amounts outstanding (including accrued
interest) under the revolving credit facility, the demand line of credit, Term
Loans A and B, the Seller Senior Subordinated promissory note and the Junior
Subordinated promissory notes (see Note 12).
 
  Line of Credit
 
     On June 28, 1996, the Group entered into a revolving credit and term loan
agreement (the Agreement) with a syndicated bank group for a $48 million
revolving line of credit (see Acquisition Financing below for discussion of term
loans). The maximum amount available to borrow is limited, as the total of all
revolving loans plus letters of credit outstanding cannot exceed the lesser of
the total line committed or 80% of net accounts receivable, as defined. This
credit agreement terminates on June 30, 2001. The Group may designate borrowings
as either Base Rate Loans or Eurodollar Loans, as defined. For Base Rate Loans,
interest on borrowings is payable quarterly in arrears beginning October 1, 1996
at an annual rate equal to the base rate plus applicable base rate margin, as
defined (10.0% at June 29, 1997 and 8.5% at June 30, 1996). For Eurodollar
Loans, interest is payable at the end of each interest period, as defined, at an
annual rate equal to the adjusted Eurodollar rate plus the applicable Eurodollar
margin, as defined (8.8% at June 29, 1997 and 8.4% at June 30, 1996). Borrowings
outstanding under this line of credit were $46,424,112 at June 29, 1997 and
$6,220,153 at June 30, 1996. The provisions of the Agreement permit the Group to
obtain letters of credit up to a maximum amount, as defined (see Note 6).
 
     The Agreement provides for certain covenants, including maintenance of
defined levels of tangible net worth, earnings before interest, taxes,
depreciation and amortization, and certain other financial ratios. The

Group was not in compliance with certain of these covenants at December 1996,
March 1997 and June 1997. Subsequently, the bank waived the Group's defaults of
these covenants and financial provisions and amended the covenants and financial
provisions through the end of fiscal 1998 which brings the Group into
compliance. Borrowings under the Agreement are collateralized by substantially
all assets of the Group. The Agreement also provides for limited recourse
guarantees and pledge agreements from certain shareholders, an affiliated
company and UFSCC.
 
     On September 23, 1996, UNICCO entered into a demand line of credit
agreement with a bank. The agreement allows UNICCO to borrow up to $5,000,000 at
the bank's discretion, for working capital purposes. The terms and conditions of
the agreement are substantially the same as those contained in the $48 million
revolving line of credit and term loan agreement described above. The agreement
has been extended to expire on December 31, 1997. Borrowings outstanding under
this line of credit were $4,162,999 at June 29, 1997.
 
     In 1995 and until the date of the AFS acquisition described in Note 2,
UNICCO had a loan agreement with a bank providing UNICCO with a $6,500,000
annually renewable line of credit, inclusive of a $3,500,000 limit for letters
of credit and a $56,000,000 revolving facility for acquisition financing. This
agreement was terminated in June, 1996.

interest period, as defined, at an annual rate equal to the adjusted Eurodollar
rate plus applicable Eurodollar margin, as defined (8.8% at June 29, 1997 and
8.4% at June 30, 1996). Interest on borrowings of Term Loan B is payable
quarterly in arrears for Base Rate Loans, at a base rate plus 2%, (10.5% at June
29, 1997 and 8.25% at June 30, 1996). For Eurodollar Loans, interest is payable
at the end of each interest period, as defined, at the Eurodollar rate plus 3.5%

mandatory principal repayments of Term Loan A and Term Loan B in the event of
asset sales and excess cash flow, as defined.
 
     On June 28, 1996, the Group entered into a $5,000,000 subordinated

and provides for quarterly interest payments based on an annual interest rate of
14%. The agreement provides for maintenance of certain financial ratio
covenants. The agreement includes a limited recourse guarantee from a principal
shareholder and UFSCC, as well as a pledge agreement from such shareholder.
 
     In connection with the AFS acquisition (Note 2), UNICCO entered into a
$12,000,000 subordinated promissory note agreement with the seller. The
promissory note is subordinated to the line of credit, Term Loans A and B, and
the MCRC loan described above, and is due on September 30, 2001. The agreement
provides for quarterly interest payments based on an annual interest rate of 8%
and includes a limited recourse guarantee from a key shareholder and UFSCC, as
well as a pledge agreement from a key shareholder. The approximate fair value of
this note at June 29, 1997 and June 30, 1996 was $9,878,400 and $9,348,000,
respectively. As more fully described in Notes 2 and 3, the favorable financing
associated with this note has been considered in the Group's purchase accounting
for the acquisition resulting in a $2,652,000 debt discount which is being
amortized over the five-year term of the note.
 
     Junior subordinated promissory note agreements were issued in July 1997 to
certain shareholders of the Group for approximately $3 million. The promissory
notes are due on October 1, 2001 and provide for annual interest payments at
15%.
 
     Minimum future payments of long-term debt are as follows:

5.  TRANSACTIONS WITH RELATED PARTIES
 
  Notes Receivable From Officers
 
     Notes receivable from officers consist primarily of demand notes receivable
from officers/shareholders bearing interest at the applicable federal rate. The
long-term portion of the notes receivable represents the portion the Group will
not collect within the next year, in accordance with the repayment terms.
Interest income of approximately $56,000, $77,000 and $83,000 related to these
loans are included in the accompanying combined consolidated statements of
income during 1997, 1996 and 1995, respectively. Interest receivable related to
these notes was approximately $312,000 and $367,000 at June 29, 1997 and June
30, 1996, respectively.
 
     On June 24, 1996, UNICCO loaned an officer of the Group approximately
$217,000 to purchase 27 shares of nonvoting common stock. This loan bears
interest at an average of the Applicable Federal Rate (5.68% at June 29, 1997
and 5.8% at June 30, 1996), is due on July 1, 2001 and is classified as a
deduction from shareholders' equity in the accompanying combined consolidated
balance sheet.
 
     In connection with the loan agreements discussed in Note 4, certain notes
receivable from officers and shareholders have been assigned to the lenders
under such loan agreements.
 
  Demand Note Payable To An Officer
 
     The demand note payable to an officer of approximately $282,000, included
in the accompanying combined consolidated balance sheet, bears interest at the
prime rate or 20%, whichever is greater. This note was paid in full, including
accrued interest, on September 3, 1997.

  Junior Subordinated Promissory Notes
 
     In connection with the AFS acquisition (see Note 2), certain shareholders
loaned the Companies $3,000,003 (see Note 4).
 
  Lease Agreement With An Affiliate
 
     The Group leases certain office space from an affiliated company. The
agreement commenced on July 1, 1995 and will be effective for a term of five
years and five months. Approximate future minimum payments under this lease are
$51,800 per year from July 1996 through June 1998, and $57,000 per year from
July 1998 through November 2000. Such amounts are included in Note 6.
 
  Insurance Agreement With An Affiliate
 
     Prior to the end of fiscal 1995, the Group insured its workers'
compensation and general liability risks through a combination of a
self-insurance program and indemnity coverage obtained from a third-party
carrier. At the end of fiscal 1995, the Group entered into an agreement with a
commercial insurance carrier whereby its workers' compensation and general
liability insurance risks are reinsured with an affiliated company. Under the
terms of this arrangement, the Group's obligations with respect to workers'
compensation and general liability claims are limited to the premiums paid for
such insurance. The Group's insurance premiums are actuarially determined based
on its historical loss experience. The amount charged to expense related to the
arrangement was approximately $10,129,000, $3,501,000 and $1,244,000 in fiscal
1997, fiscal 1996 and fiscal 1995, respectively. Included in prepaid insurance
as of June 29, 1997 and June 30, 1996 are amounts of $0 and approximately
$2,026,000, respectively, related to this agreement. The affiliated company's
outstanding common stock has been pledged by the shareholder as collateral for
the Agreement described in Note 4.
 
     Included in the Group's combined consolidated results of operations for the
year ended June 30, 1996 is approximately $929,000 in income representing
refunds received in fiscal 1996 from a third-party insurance carrier as a result
of the Group's ultimate favorable claims experience from accident years prior to
fiscal 1996. Additionally, in fiscal 1996, as a result of the Company's
sustained favorable experience with respect to its self insurance program and,
as discussed above, the establishment of the reinsurance arrangement at the end
of fiscal 1995, the Company reevaluated its reserve requirements and reversed
approximately $1,148,000 of workers' compensation and general liability
insurance reserves.
 
6. COMMITMENTS AND CONTINGENCIES
 
  Operating Leases
 
     The Group leases certain equipment and facilities under noncancelable
operating leases through June 30, 2005. Rent expense under these leases was
approximately $3,207,000, $1,095,000 and $999,000 for the years ended June 29,
1997, June 30, 1996 and June 25, 1995, respectively. The approximate future
minimum payments under these leases are as follows:

     The Group leases certain facilities under tenancy-at-will agreements, which
are not included in the future minimum lease payments above. Future payments
above do not include the lease of a warehouse at an annual cost of approximately
$222,000 through 2001, which is fully reimbursed by a customer.
 
  Letters of Credit
 
     As of June 29, 1997, the Group was contingently liable under certain
letters of credit, in the aggregate amount of approximately $1,556,000,
primarily issued in connection with the Group's surety bonding arrangements. The
letters of credit expire on various dates through June 30, 2000.
 
  Stock Repurchase Agreement
 
     All nonvoting common shares (see Note 8) must be redeemed by the Group at
the then book value of the shares, as defined, in the event that the
shareholders cease employment with the Group.
 
  Litigation
 
     UNICCO was a party to a lawsuit filed in May 1994 by a former employee who
alleged breach of contract and misrepresentation in connection with his
employment. In 1996, the parties to the lawsuit reached agreement to settle the
litigation pursuant to a court-ordered mediation of the claims. The settlement
amount (approximately $400,000) is included in selling, general and
administrative expenses in the accompanying statement of income for fiscal 1996.
 
     In the ordinary course of business, the Group is party to various types of
litigation. The Group 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 Group's financial position or results of
operations.
 
7.  INCOME TAXES
 
     UNICCO has elected to be taxed as an S corporation for federal and certain
state income tax purposes and is a business trust for Massachusetts state tax
purposes. UNICCO's provision for income taxes in 1997 and 1996 results from
states that do not recognize its S corporation status for state income tax
purposes and its business trust status in Massachusetts.
 
     Effective January 1, 1997, USC elected to be taxed as an S corporation for
federal and certain state income tax purposes. Prior to January 1, 1997, USC was
a C corporation and was subject to federal and state income taxes at the
corporate level.
 
     Income before income tax expense was taxed under the following
jurisdictions:

     As a cash basis tax payer, UNICCO generated an operating loss of
approximately $29,350,000 for income tax purposes in fiscal 1997, primarily as a
result of the increase in working capital from its June 28, 1996 acquisition of
AFS (Note 2). Such operating losses, which are limited to those states which do
not recognize UNICCO's subchapter S status, are further limited to the
carryforward period for each respective state in which such loss was generated,
generally ranging from three to fifteen years. Management believes that it is
more likely than not that it will realize approximately $370,000 of the tax
benefit associated with the operating loss described above. This belief is based
upon a review of all available evidence, including historical operating results,
projections of future taxable income, recognizing the limitations described
above, and tax planning strategies. The Group has recorded a valuation allowance
against the remaining portion of the tax benefit related to the above referenced
operating losses.

9.  EMPLOYEE BENEFIT PLANS
 
  Multi-employer Pension Plans
 
     Certain employees under collective bargaining agreements are covered by
union-sponsored, multi-employer pension plans. Group contributions, generally
based on hours worked, are in accordance with negotiated labor contracts. The
Group recorded expenses of approximately $5,398,000, $703,000 and $561,000 in
fiscal 1997, 1996 and 1995, respectively, related to the plans. Information is
not readily available for the Group to determine its share of unfunded vested
benefits, if any, under the plans.
 
  401(k) Investment Savings Plans
 
     UNICCO maintains two 401(k) retirement plans (the "Plans") covering all
employees who have completed one year of service, as defined, and are not
subject to a collective bargaining agreement. The Plans allow eligible employees
to make salary-deferred contributions for not less than 1% nor more than 20% of
their compensation for the contribution period, as defined, subject to certain
IRS limitations. UNICCO may contribute to the Plans in any year at its
discretion. UNICCO made contributions of approximately $1,017,000, $32,000 and
$33,000 in fiscal 1997, 1996 and 1995, respectively.

10.  RESIGNATION OF OFFICERS
 
     On January 3, 1996, one of UNICCO's officers and shareholders resigned.
UNICCO repurchased the officer's 55 nonvoting outstanding shares for
approximately $444,000. The former officer also signed a noncompete agreement
with UNICCO for approximately $800,000, which UNICCO has capitalized and is
amortizing over the life of the noncompete agreement. The provisions of the
agreement require monthly payments of approximately $23,000, commencing on
January 1, 1996 through December 31, 1998, subject to the former officer not
competing with the Group. Further, the agreement provides for such payments to
cease and reimbursement of all payments previously made under the terms of the
arrangement if the former officer violates the agreement. Amortization expense
on the noncompete agreement was approximately $267,500 and $134,000 for the
years ended June 29, 1997 and June 30, 1996, respectively.
 
  Unaudited
 
     In July 1997 one of UNICCO's officers resigned. The severance agreement
with the officer provides for periodic payments totalling approximately
$370,000. Such amount is included in the accompanying condensed combining
consolidating financial statements.
 
11.  CONDENSED COMBINING CONSOLIDATING FINANCIAL INFORMATION OF GUARANTOR
SUBSIDIARIES
 
     Each guarantor subsidiary of UNICCO is directly or indirectly wholly-owned
and the guarantees related to the Series A Note Offering are full, unconditional
and joint and several. UFSCC is indirectly wholly-owned and is not a guarantor
of this debt. Separate financial statements of the guarantor subsidiaries are
not presented because management has determined that they would not be material
to investors. However, condensed combining consolidating financial information
as of June 29, 1997 and for the year then ended, and as of September 28, 1997
and for the three months then ended (unaudited) are presented. The following
presents condensed combining consolidating financial information (rounded to the
nearest thousand) for (i) UNICCO only, (ii) the guarantor subsidiaries on a
combined basis, (iii) the nonguarantor subsidiary -- UFSCC and (iv) the Group on
a combined consolidated basis (see Note 12).

       NOTES TO COMBINED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
12.  SUBSEQUENT EVENT (UNAUDITED)
 
     On October 17, 1997 the Group consummated the Series A Note Offering and
entered into the Amended Facility. The net proceeds from the Series A Note
Offering and the Amended Facility were used to repay approximately $83.2 million
of indebtedness under the Group's existing credit facilities and $16.8 million
of certain other indebtedness, fees and expenses incurred in connection with
such financing. The Group recorded a $3.0 million extraordinary charge related
to such repayments in the second quarter of fiscal 1998.
 
     The Series A Note Offering will mature on October 15, 2007. The Notes will
not be redeemable at the issuers' option prior to October 15, 2002. Thereafter,
the Notes will be subject to redemption at any time at the option of the issuers
at redemption prices set forth in the Notes. Interest on the Notes will accrue
at the rate of 9 7/8% per annum and will be 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 will be subordinated in right to the
prior payment of all Senior Debt, as defined.
 
     Upon the occurrence of a change in control, as defined, the issuers will be
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. Restrictions under
the Notes and the Amended Facility include certain sales of assets, certain
payments of dividends and incurrence of debt, and limitations on certain mergers
and transactions with affiliates. With respect to the Amended Facility, the
Company will be required to maintain certain financial ratios and covenants
which are similar to the credit facility in existence on September 28, 1997.
 
     As previously discussed, the accompanying combined consolidated financial
statements include the accounts of UNICCO and USC, Inc., which are owned and
controlled by common shareholders. In connection with the Offering, the
shareholders of UNICCO contributed their ownership interests in USC, Inc. to
UNICCO. As a result, all of the operations of the Group will be conducted
through UNICCO and its wholly-owned subsidiaries. This transaction will be
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.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Trustees and Shareholders of
UNICCO Service Company and the
Board of Directors and Shareholders of USC, Inc.
 
     In our opinion, the accompanying combined statements of income and of cash
flows present fairly, in all material respects, the results of operations and
cash flows of the Allied Facility Services Business ("Services Business") for
the years ended June 28, 1996 and June 30, 1995, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Services Business' 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.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 The Business
 
     On June 28, 1996, UNICCO Service Company, ("UNICCO"), USC, Inc. ("USC") and
UNICCO Facility Services Canada Company ("UFSCC"), collectively "the Group",
affiliated and consolidated companies with common shareholders, acquired the
Allied Facility Services Business ("Services Business"), exclusive of the
operations in and surrounding the metropolitan New York City area (the "Excluded
Operations"), from the Services Business' parent in accordance with the Purchase
Agreement (the "Agreement") dated May 3, 1996. Under the terms of the Agreement,
the Group acquired i) certain assets, liabilities and operations of the facility
services business, exclusive of the Excluded Operations and ii) the stock of the
government and security businesses. The Services Business provides the following
services to its customers in the United States and Canada: janitorial services;
facility management services; mechanical maintenance; building security and
office services. Customers of the Services Business include corporate
headquarters, colleges and universities, financial institutions, governmental
agencies, healthcare facilities, industrial plants, tourism and convention
centers, retail malls and property management companies.
 
 Basis of Presentation
 
     The combined financial statements have been prepared by combining the
operating results and cash flows of the Services Business and reflecting the
allocation of certain overhead expenses (see Note 2).
 
 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 amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
 Insurance Costs
 
     Included in the accompanying combined financial statements are workers'
compensation and general liability insurance premiums and claims costs, handled
under a parent company insurance program. These amounts are actuarially
determined based upon the loss experience of the Services Business and amounted
to $12,021,000 and $10,648,000 in fiscal 1996 and 1995, respectively. These
costs are included in cost of service revenues. For the Services Business'
foreign operations, the insurance costs are incurred directly under government
directed programs.
 
 Revenue Recognition
 
     Service revenues are generated primarily by efforts expended on cost-plus
fixed-fee, fixed price and time and material contracts. Revenue from cost-plus
fixed-fee contracts is recognized on the basis of direct and indirect expenses
incurred plus the allocable portion of the fixed fee. Revenues on fixed price
contracts are recognized based on the monthly amount as stipulated in the
contract and the performance of services. Revenues under time and material
contracts are recorded at the contracted rates as labor efforts are expended and
other direct costs are incurred. Losses, if any, are provided for at the time
that management determines that costs, including estimated costs to complete,
exceed contract revenue.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially expose the Services Business to
concentrations of credit risk consist primarily of trade accounts receivable. To
minimize this risk, ongoing credit evaluations of customers' financial condition
are performed, although collateral is not required. In addition, the Services
Business

maintains allowances for potential uncollectible amounts and such amounts, in
the aggregate, have not exceeded management's expectations.
 
  Depreciation and Amortization
 
     The Services Business provides for depreciation and amortization by charges
to operations in amounts that allocate the cost of property, equipment and
leasehold improvements over their estimated useful lives using the straight-line
method as follows:

  Foreign Currency Translation
 
     In accordance with Statement of Financial Accounting Standards No. 52,
Foreign Currency Translation, the statements of income and of cash flows of the
Services Business' Canadian operations included in the combined financial
statements have been translated at average exchange rates for the respective
reporting periods. The impact of such translation is not significant in the
years ended June 28, 1996 and June 30, 1995.
 
  Income Taxes
 
     Historically, the results of the Services Business' operations have been
included in the consolidated income tax returns of its parent. The provision for
income taxes included in these financial statements have been calculated as if
the Services Business were a stand-alone taxpayer.
 
     The provisions of Statement of Financial Accounting Standards No.109 ("FAS
109") have been applied to these financial statements. FAS 109 is an asset and
liability approach that requires the recognition of deferred tax assets and
liabilities for the expected future consequences of events that have been
recognized in the financial statements or tax returns. In estimating future tax
consequences, FAS 109 generally considers all expected future events other than
anticipated changes in the tax laws or rates.
 
2.  RELATED PARTY TRANSACTIONS
 
  Corporate Administrative Services
 
     Historically, the Services Business was not allocated or charged its
portion of corporate expenses. For purposes of these financial statements, such
expenses have been allocated, including executive management and corporate
overhead; employee benefit administration; information systems services; risk
management/insurance administration; tax and treasury/cash management services;
litigation administration services and other corporate support functions.
 
     All of the allocations and charges described above are included in selling,
general and administrative expenses in the accompanying combined financial
statements. Such allocations and charges are based on either a direct cost pass
through or a percentage of total costs for the services provided based on
factors such as headcount, management time or the specific level of activity
directly related to such costs (i.e., checks processed, etc.). Such allocations
and charges totaled approximately $3,943,000 and $3,365,000 for the years ended
June 28, 1996 and June 30, 1995, respectively. Management believes that the
basis of allocation is reasonable, however, such allocated expenses may differ
from those that the Services Business would incur if it operated as stand-alone
entity. Management does not believe it is practicable to quantify these expenses
as if the Services Business operated as a stand-alone entity.

  Litigation
 
     The Services Business was a defendant to a class action lawsuit resulting
from the release of certain contaminants into the groundwater and air from a
facility owned by one of its customers (the Customer). The Services Business

ITEM 22.  UNDERTAKINGS.
 
     Each undersigned Registrant hereby undertakes:
 
     (a)(l) 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 of 1933;
 
          (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 and of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement;
 
          (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 of 1933, 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.
 
     (b) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the Registration Statement 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.
 
     (c) That, insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant 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 registrant 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
 
                                      II-2
<PAGE>   126
 
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
     (d) To respond to requests for information that is incorporated by
reference into the Prospectus pursuant to Items 4, 10 (b), 11 or 13 of this
Form, within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means. This
includes information contained in documents filed subsequent to the effective
date of the Registration Statement through the date of responding to the
request.
 
     (e) To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the Registration Statement when it became
effective.

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
undersigned registrant has duly caused this Registration Statement to be signed
on its behalf by the undersigned, hereunto duly authorized, in the City of
Boston, Commonwealth of Massachusetts, on December 15, 1997.

BANCBOSTON SECURITIES INC.
100 Federal Street
Boston, Massachusetts  02110


Ladies & Gentlemen:

                  UNICCO Service Company, a Massachusetts business trust (the
"COMPANY"), and UNICCO Finance Corp., a Delaware corporation ("FINANCE" and,
together with the Company, the "ISSUERS"), as joint and several obligors,
propose to issue and sell to BancBoston Securities Inc. (the "INITIAL
PURCHASER") $105,000,000 in aggregate principal amount of 9 7/8% Series A Senior
Subordinated Notes due 2007 (the "SERIES A NOTES"), subject to the terms and
conditions set forth herein. The Series A Notes will be issued pursuant to an
indenture (the "INDENTURE"), to be dated the Closing Date (as defined), among
the Issuers, the Guarantors (as defined) and State Street Bank and Trust
Company, as trustee (the "TRUSTEE"). The Notes (as defined) will be fully and
unconditionally guaranteed (the "GUARANTEES") as to payment of principal,
interest, liquidated damages and premium, if any, on an unsecured senior
subordinated basis, jointly and severally, by each entity listed on EXHIBIT A
hereto (collectively, the " GUARANTORS"). Capitalized terms used herein and not
otherwise defined shall have the meanings assigned to such terms in the
Indenture.

                  In connection with the offering of the Series A Notes, the
shareholders of the Company will contribute their interests in affiliated
entities of the Company to the Company (the "Refinancing"). As a result of the
Refinancing, such affiliated entities will become subsidiaries of the Company.

         1.       ISSUANCE OF SECURITIES. The Issuers propose, upon the terms 
and subject to the conditions set forth herein, to issue and sell to the Initial
Purchaser an aggregate of $105,000,000 in principal amount of Series A Notes.
The Series A Notes and the Series B Notes (as defined) issuable in exchange
therefor are collectively referred to herein as the "NOTES."

         Upon original issuance thereof, and until such time as the same is no
longer required under the applicable requirements of the Securities Act of 1933,
as amended (the "ACT"), the Series A Notes (and all securities issued in
exchange therefor or in substitution thereof) shall bear the following legend:



                                       1
<PAGE>   3

         "THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY
         ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE
         UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
         ACT"), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD,
         PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
         AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY
         EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON
         THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
         PROVIDED BY RULE 144A THEREUNDER. BY ITS ACQUISITION HEREOF, THE HOLDER
         (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2),
         (3) OR (7) UNDER THE SECURITIES ACT) OR (C) IT IS NOT A U.S. PERSON AND
         IS NOT ACQUIRING THIS SECURITY FOR THE ACCOUNT OR BENEFIT OF A U.S.
         PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT. THE HOLDER OF
         THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE ISSUERS
         THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED,
         ONLY (1)(a) TO A PERSON WHO 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, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER
         THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON
         IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE
         SECURITIES ACT OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
         REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN
         OPINION OF COUNSEL IF THE ISSUERS SO REQUEST), (2) TO THE ISSUERS, (3)
         PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
         ACT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES
         LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE
         JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
         REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE SECURITY EVIDENCED
         HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE."

         2.       OFFERING. The Series A Notes will be offered and sold to the 
Initial Purchaser pursuant to an exemption from the registration requirements
under the Act. The Issuers have prepared a preliminary offering memorandum,
dated September 26, 1997 (the "PRELIMINARY OFFERING MEMORANDUM"), and a final
offering memorandum, dated October 14, 1997 (the "OFFERING MEMORANDUM"),
relating to the Company, its subsidiaries and the Series A Notes.


         The Initial Purchaser has advised the Issuers that the Initial
Purchaser will make offers (the "EXEMPT RESALES") of the Series A Notes on the
terms set forth in the Offering Memorandum, as amended or supplemented, solely
to (i) persons whom the Initial Purchaser reasonably believes to be "qualified
institutional buyers," as defined in Rule 144A under the Act ("QIBS"), (ii) a
limited number of persons who have represented to the Issuers that they are
institutional "Accredited Investors" referred to in Rule 501(a)(1), (2), (3) or
(7) under the Act (each, an "ACCREDITED INVESTOR") and (iii) non-U.S. persons
outside 




                                       2

<PAGE>   4

the United States in reliance upon Regulation S ("REGULATION S") under the Act
(each, a "REG S INVESTOR"). The QIBs, Accredited Investors and Reg S Investors
are collectively referred to herein as the "ELIGIBLE PURCHASERS." The Initial
Purchaser will offer the Series A Notes to such Eligible Purchasers initially at
a price equal to 99.53% of the principal amount thereof. Such price may be
changed at any time without notice.

         Holders (including subsequent transferees) of the Series A Notes will
have the registration rights set forth in the registration rights agreement
relating thereto (the "REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing
Date, for so long as such Series A Notes constitute "TRANSFER RESTRICTED
SECURITIES" (as defined in the Registration Rights Agreement). Pursuant to the
Registration Rights Agreement, the Issuers and the Guarantors will agree to file
with the Securities and Exchange Commission (the "COMMISSION"), under the
circumstances set forth therein, (i) a registration statement under the Act (the
"EXCHANGE OFFER REGISTRATION STATEMENT") relating to the 9 7/8% Series B Notes
due 2007 (the "SERIES B NOTES") to be offered in exchange for the Series A Notes
(the "EXCHANGE OFFER") and (ii) a shelf registration statement pursuant to Rule
415 under the Act (the "SHELF REGISTRATION STATEMENT" and, together with the
Exchange Offer Registration Statement, the "REGISTRATION STATEMENTS") relating
to the resale by certain holders of the Series A Notes, and to use their best
efforts to cause such Registration Statements to be declared effective and to
consummate the Exchange Offer. This Agreement, the Notes, the Guarantees, the
Indenture, the Registration Rights Agreement and the Amended Credit Facility (as
defined in the Offering Memorandum) are hereinafter referred to collectively as
the "OPERATIVE DOCUMENTS."

         3.       PURCHASE, SALE AND DELIVERY. (a) On the basis of the 
representations, warranties and covenants contained in this Agreement, and
subject to its terms and conditions, the Issuers agree to issue and sell to the
Initial Purchaser, and the Initial Purchaser agrees to purchase from the
Issuers, all of the Series A Notes. The purchase price for the Series A Notes
will be $965.441 per $1,000 principal amount Series A Note.

         (b) Delivery of the Series A Notes shall be made, against payment of
the purchase price therefor, at the offices of Posternak, Blankstein & Lund,
L.L.P., Boston, Massachusetts or such other location as may be mutually
acceptable. Such delivery and payment shall be made at 9:00 a.m., New York City
time, on October 17, 1997 or at such other time as shall be agreed upon by the
Initial Purchaser and the Issuers. The time and date of such delivery and
payment are herein called the "CLOSING DATE."

         (c) On the Closing Date, one or more Series A Notes in definitive form,
registered in the name of Cede & Co., as nominee of The Depository Trust Company
("DTC"), having an aggregate amount corresponding to the aggregate amount of the
Series A Notes sold pursuant to Exempt Resales to Eligible Purchasers (the
"GLOBAL NOTES") shall be delivered by the Issuers to the Initial Purchaser (or
as the Initial Purchaser directs), against payment by the Initial Purchaser of
the purchase price therefor, by wire transfer of same day funds, to an account
designated by the Issuers, provided that the Issuers shall give at least two
business days' prior written notice to the Initial Purchaser of the information
required to effect such wire transfer. The Global Notes shall be made available
to the Initial Purchaser for inspection not later than 9:30 a.m. on the business
day immediately preceding the Closing Date.

         4.       AGREEMENTS OF THE ISSUERS. The Issuers covenant and agree with
the Initial Purchaser as follows:

                  (a) To advise the Initial Purchaser promptly and, if requested
         by the Initial Purchaser, confirm such advice in writing, (i) of the
         issuance by any state securities commission of any stop order
         suspending the qualification or exemption from qualification of any
         Notes for offering or sale in any jurisdiction, or the initiation of
         any proceeding for such purpose by any state securities 



                                       3

<PAGE>   5

         commission or other regulatory authority and (ii) of the happening of
         any event that makes any statement of a material fact made in the
         Preliminary Offering Memorandum or the Offering Memorandum untrue or
         that requires the making of any additions to or changes in the
         Preliminary Offering Memorandum or the Offering Memorandum in order to
         make the statements therein, in the light of the circumstances under
         which they are made, not misleading. The Issuers shall use their
         reasonable best efforts to prevent the issuance of any stop order or
         order suspending the qualification or exemption of any Notes under any
         state securities or Blue Sky laws and, if at any time any state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption of any Notes or
         Guarantees of Notes under any state securities or Blue Sky laws, the
         Issuers shall use their reasonable best efforts to obtain the
         withdrawal or lifting of such order at the earliest possible time.

                  (b) To furnish the Initial Purchaser and those persons
         identified by the Initial Purchaser to the Issuers, without charge, as
         many copies of the Preliminary Offering Memorandum and the Offering
         Memorandum, and any amendments or supplements thereto, as the Initial
         Purchaser may reasonably request. The Issuers consent to the use of the
         Preliminary Offering Memorandum and the Offering Memorandum, and any
         amendments and supplements thereto required pursuant hereto, by the
         Initial Purchaser in connection with Exempt Resales.

                  (c) Not to amend or supplement the Preliminary Offering
         Memorandum or the Offering Memorandum prior to the Closing Date unless
         the Initial Purchaser shall previously have been advised thereof and
         shall not have objected thereto within a reasonable time after being
         furnished a copy thereof. The Issuers shall promptly prepare, upon the
         Initial Purchaser's request, any amendment or supplement to the
         Preliminary Offering Memorandum or the Offering Memorandum that may be
         necessary or advisable in connection with Exempt Resales.

                  (d) If, after the date hereof and prior to consummation of any
         Exempt Resale, any event shall occur as a result of which, in the
         judgment of the Issuers or in the reasonable opinion of counsel for the
         Issuers or counsel for the Initial Purchaser, it becomes necessary or
         advisable to amend or supplement the Preliminary Offering Memorandum or
         the Offering Memorandum in order to make the statements therein, in the
         light of the circumstances when such Offering Memorandum is delivered
         to an Eligible Purchaser which is a prospective purchaser, not
         misleading, or if it is necessary or advisable to amend or supplement
         the Preliminary Offering Memorandum or Offering Memorandum to comply
         with applicable law, (i) to notify the Initial Purchaser and (ii)
         forthwith to prepare an appropriate amendment or supplement to such
         Preliminary Offering Memorandum or Offering Memorandum so that the
         statements therein as so amended or supplemented will not, in the light
         of the circumstances when it is so delivered, be misleading, or so that
         such Preliminary Offering Memorandum or Offering Memorandum will comply
         with applicable law.

                  (e) To cooperate with the Initial Purchaser and counsel for
         the Initial Purchaser in connection with the qualification or
         registration of the Series A Notes under the securities or Blue Sky
         laws of such jurisdictions as the Initial Purchaser may reasonably
         request and to continue such qualification in effect so long as
         required for the Exempt Resales; provided, however, that none of the
         Issuers shall be required in connection therewith to register or
         qualify as a foreign corporation where it is not now so qualified or to
         take any action that would subject it to service of process in suits or
         taxation, in each case, other than as to matters and transactions
         relating to the Preliminary Offering Memorandum, the Offering
         Memorandum or Exempt Resales, in any jurisdiction where it is not now
         so subject.

         Agreement are consummated or this Agreement becomes effective or is

         issuance, transfer and delivery of the Notes and the Guarantees to the
         Initial Purchaser, (iii) the qualification or registration of the Notes
         and the Guarantees for offer and sale under the securities or Blue Sky
         laws of the several states (including, without limitation, the cost of
         printing and mailing a preliminary and final Blue Sky Memorandum and
         the reasonable fees and disbursements of counsel for the Initial
         Purchaser relating thereto), (iv) furnishing such copies of the
         Preliminary Offering Memorandum and the Offering Memorandum, and all
         amendments and supplements thereto, as may be requested for use in

         the Notes and the Guarantees (including, without limitation, printing

         the Notes.

                  (g) To use the proceeds from the sale of the Series A Notes in
         the manner described in the Offering Memorandum under the caption "Use
         of Proceeds."

                  (h) Not to voluntarily claim, and to resist actively any
         attempts to claim, the benefit of any usury laws against the holders of
         any Notes.

                  (i) To do and perform all things required to be done and

                  (j) Not to sell, offer for sale or solicit offers to buy or
         otherwise negotiate in respect of any security (as defined in the Act)

         with respect to the employees of the Company or any of its
         subsidiaries. To the best knowledge of the Issuers, no collective
         bargaining organizing activities are taking place with respect to the
         Company or any of its subsidiaries, except those activities that could
         not reasonably be expected to have a Material Adverse Effect. None of
         the Company or any of its subsidiaries has violated (A) any federal,
         state or local law or foreign law relating to discrimination in hiring,
         promotion or pay of employees, (B) any applicable wage or hour laws or
         (C) any provision of the Employee Retirement Income Security Act of
         1974, as amended ("ERISA"), or the rules and regulations thereunder,
         except those violations that could not reasonably be expected to have a
         Material Adverse Effect.

                  (xxiii) None of the Company or any of its subsidiaries has
         violated any foreign, federal, state or local law or regulation
         relating to the protection of human health and safety, the environment
         or hazardous or toxic substances or wastes, pollutants or contaminants
         ("ENVIRONMENTAL LAWS") which violation could reasonably be expected to
         have a Material Adverse Effect.

                  (xxiv) There is no alleged liability, nor, to the best
         knowledge of the Issuers, any reasonable basis for liability
         (including, without limitation, alleged or potential liability for
         investigatory costs, cleanup costs, governmental response costs,
         natural resource damages, property damages, personal injuries or
         penalties) of the Company or any of its subsidiaries arising out of,
         based on or resulting from (A) the presence or release into the
         environment of any Hazardous Material (as defined) at any location,
         whether or not owned by the Company or such subsidiary, as the case may
         be, or (B) any violation or alleged violation of any Environmental Law,
         which alleged or potential liability is required to be disclosed in the
         Offering Memorandum, other than as disclosed therein, or could
         reasonably be expected to have a Material Adverse Effect. The term
         "HAZARDOUS MATERIAL" means (i) any "hazardous substance" as defined by
         the Comprehensive Environmental Response, Compensation and Liability
         Act of 1980, as amended, (ii) any "hazardous waste" as defined by the
         Resource Conservation and Recovery Act, as amended, (iii) any petroleum
         or petroleum product, (iv) any polychlorinated biphenyl, and (v) any
         pollutant or contaminant or hazardous, dangerous or toxic chemical,
         material, waste or substance regulated under or within the meaning of
         any other law relating to protection of human health or the environment
         or imposing liability or standards of conduct concerning any such
         chemical material, waste or substance.

                  (xxv) Each of the Company and its subsidiaries has and, after
         giving effect to the Refinancing, will have such permits, licenses,
         franchises and authorizations of governmental or regulatory authorities
         ("PERMITS"), including, without limitation, under any applicable
         Environmental Laws, as are necessary to own, lease and operate their
         respective properties and to conduct their businesses except where the
         failure to have such permits could not reasonably be expected to have a
         Material Adverse Effect; each of the Company and its subsidiaries has
         fulfilled and performed all of its obligations with respect to such
         permits and no event has occurred which allows, or after notice or
         lapse of time would allow, revocation or termination thereof or results
         in any other material impairment of the rights of the holder of any
         such permit; and such permits 



                                       11

<PAGE>   13

         contain no restrictions that are materially burdensome to the Company
         or such subsidiary, as the case may be.

                  (xxvi) Each of the Company and its subsidiaries has and, after
         giving effect to the Refinancing, will have (A) good and marketable
         title to all of the properties and assets described in the Offering
         Memorandum as owned by it, free and clear of all liens, charges,
         encumbrances and restrictions (except for Permitted Liens (as defined
         in the Indenture) and taxes not yet payable), (B) peaceful and
         undisturbed possession under all material leases to which any of them
         is a party as lessee and each of which lease is valid and binding and
         no default exists thereunder, except for defaults that could not
         reasonably be expected to have a Material Adverse Effect, (C) all
         licenses, certificates, permits, authorizations, approvals, franchises
         and other rights from, and has made all declarations and filings with,
         all federal, state and local authorities, all self-regulatory
         authorities and all courts and other tribunals (each, an
         "AUTHORIZATION") necessary to engage in the business conducted by any
         of them in the manner described in the Offering Memorandum and (D) no
         reason to believe that any governmental body or agency is considering
         limiting, suspending or revoking any such Authorization. All such
         Authorizations are and, after giving effect to the Refinancing, will be
         valid and in full force and effect and each of the Company and its
         subsidiaries is in compliance in all material respects with the terms
         and conditions of all such Authorizations and with the rules and
         regulations of the regulatory authorities having jurisdiction with
         respect thereto. All material leases to which the Company or any of its
         subsidiaries is a party are valid and binding and no default by the
         Company or such subsidiary, as the case may be, has occurred and is
         continuing thereunder and, to the best knowledge of the Issuers, no
         material defaults by the landlord are existing under any such lease,
         except those defaults that could not reasonably be expected to have a
         Material Adverse Effect.

                  (xxvii) Each of the Company and its subsidiaries owns,
         possesses or has the right to employ all patents, patent rights,
         licenses, inventions, copyrights, know-how (including trade secrets and
         other unpatented and/or unpatentable proprietary or confidential
         information, software, systems or procedures), trademarks, service
         marks and trade names, inventions, computer programs, technical data
         and information (collectively, the "INTELLECTUAL PROPERTY") presently
         employed by it in connection with the businesses now operated by it or
         that are proposed to be operated by it free and clear of and without
         violating any right, claimed right, charge, encumbrance, pledge,
         security interest, restriction or lien of any kind of any other person,
         and none of the Company or any of its subsidiaries has received any
         notice of infringement of or conflict with asserted rights of others
         with respect to any of the foregoing. The use of the Intellectual
         Property in connection with the business and operations of the Company
         or any of its subsidiaries does not infringe on the rights of any
         person, except as could not reasonably be expected to have a Material
         Adverse Effect.

                  (xxviii) All material tax returns required to be filed by the
         Company or any of its subsidiaries in all jurisdictions have been so
         filed. All material taxes, including withholding taxes, penalties and
         interest, assessments, fees and other charges due or claimed to be due
         from such entities or that are due and payable have been paid, other
         than those being contested in good faith and for which adequate
         reserves have been provided or those currently payable without penalty
         or interest. To the knowledge of the Issuers, there are no material
         proposed additional tax assessments against the Company or any of its
         subsidiaries, or the assets or property of the Company or any of its
         subsidiaries, except those tax assessments for which adequate reserves
         have been established.

                  (xxix) None of the Company or any of its subsidiaries is and,
         after giving effect to the 



                                       12

<PAGE>   14

         Refinancing, will be an "investment company" or a company "controlled"
         by an "investment company" within the meaning of the Investment Company
         Act of 1940, as amended (the "INVESTMENT COMPANY ACT").

                  (xxx) There are no holders of securities of the Company or any
         of its subsidiaries who, by reason of the execution by the Issuers and
         the Guarantors of this Agreement or any other Operative Document or the
         consummation by the Issuers and the Guarantors of the transactions
         contemplated hereby and thereby, have the right to request or demand
         that the Company or any of its subsidiaries register under the Act or
         analogous foreign laws and regulations securities held by them.

                  (xxxi) Each of the Company and its subsidiaries maintains a
         system of internal accounting controls sufficient to provide reasonable
         assurance that: (A) transactions are executed in accordance with
         management's general or specific authorizations; (B) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain accountability for assets; (C) access to assets is permitted
         only in accordance with management's general or specific authorization;
         and (D) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect thereto.

                  (xxxii) Each of the Company and its subsidiaries maintains
         insurance covering its properties, operations, personnel and
         businesses, insuring against such losses and risks as are consistent
         with industry practice to protect the Company and its subsidiaries and
         their respective businesses. None of the Company or any of its
         subsidiaries has received notice from any insurer or agent of such
         insurer that substantial capital improvements or other expenditures
         will have to be made in order to continue such insurance.

                  (xxxiii) None of the Company or any of its subsidiaries has
         (A) taken, directly or indirectly, any action designed to, or that
         might reasonably be expected to, cause or result in stabilization or
         manipulation of the price of any security of the Company or any of its
         subsidiaries to facilitate the sale or resale of the Notes or (B) since
         the date of the Preliminary Offering Memorandum (1) sold, bid for,
         purchased or paid any person any compensation for soliciting purchases
         of the Notes or (2) paid or agreed to pay to any person any
         compensation for soliciting another to purchase any other securities of
         the Company or any of its subsidiaries.

                  (xxxiv) No registration under the Act of the Series A Notes is
         required for the sale of the Series A Notes to the Initial Purchaser as
         contemplated hereby or for the Exempt Resales assuming (A) that the
         purchasers who buy the Series A Notes in the Exempt Resales are
         Eligible Purchasers and (B) the accuracy of the Initial Purchaser's
         representations regarding the absence of general solicitation in
         connection with the sale of Series A Notes to the Initial Purchaser and
         the Exempt Resales contained herein. No form of general solicitation or
         general advertising (as defined in Regulation D under the Act) was used
         by either of the Issuers or any of their respective representatives
         (other than the Initial Purchaser, as to which the Issuers make no
         representation or warranty) in connection with the offer and sale of
         any of the Series A Notes or in connection with Exempt Resales,
         including, but not limited to, articles, notices or other
         communications published in any newspaper, magazine, or similar medium
         or broadcast over television or radio, or any seminar or meeting whose
         attendees have been invited by any general solicitation or general
         advertising. No securities of the same class as the Notes or the
         Guarantees have been issued and sold by the Company or any of its
         subsidiaries within the six-month period immediately prior to the date
         hereof.

                  (xxxv) The execution and delivery of this Agreement, the other
         Operative Documents and the sale of the Series A Notes to be purchased
         by Eligible Purchasers will not involve any prohibited transaction
         within the meaning of Section 406 of ERISA or Section 4975 of the
         Internal Revenue Code of 1986. The representation made by the Issuers
         in the preceding sentence is made in reliance upon and subject to the
         accuracy of, and compliance with, the representations and covenants
         made or deemed made by Eligible Purchasers as set forth in the Offering
         Memorandum under the caption "Notice to Investors."

                  (xxxvi) Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its date, and each amendment or supplement
         thereto, as of its date, contains the information specified in, and
         meets the requirements of, Rule 144A(d)(4) under the Act.

                  (xxxvii) Prior to the effectiveness of any Registration
         Statement, the Indenture is not required to be qualified under the
         Trust Indenture Act.

                  (xxxviii) None of the Issuers or any of their respective
         affiliates or any person acting on its or their behalf (other than the
         Initial Purchaser, as to whom the Issuers make no representation) has
         engaged or will engage in any directed selling efforts within the
         meaning of Regulation S with respect to the Series A Notes or the
         Guarantees.

                  (xxxix) The Series A Notes offered and sold in reliance on
         Regulation S have been and will be offered and sold by the Issuers only
         in offshore transactions.

                  (xl) The sale of the Series A Notes pursuant to Regulation S
         is not part of a plan or scheme by the Issuers to evade the
         registration provisions of the Act.

                  (xli) The Issuers and their respective affiliates and all
         persons acting on their behalf (other than the Initial Purchaser, as to
         whom the Issuers make no representation) have complied with and will
         comply with the offering restrictions requirements of Regulation S in
         connection with the offering of the Series A Notes outside the United
         States and, in connection therewith, the Preliminary Offering
         Memorandum and the Offering Memorandum contains or will contain the
         disclosure required by Rule 902(h).

                  (xlii) The Series A Notes sold in reliance on Regulation S
         will be represented upon issuance by a temporary global security that
         may not be exchanged for definitive securities until the expiration of
         the 40-day restricted period referred to in Rule 903(c)(3) of the Act
         and only upon certification of beneficial ownership of such Series A
         Notes by non-U.S. persons or U.S. persons who purchased such Series A
         Notes in transactions that were exempt from the registration
         requirements of the Act.

                  (xliii) Subsequent to the respective dates as of which
         information is given in the Offering Memorandum and up to the Closing
         Date, except as set forth in the Offering Memorandum, (A) none of the
         Company or any of its subsidiaries has incurred any liabilities or
         obligations, direct or contingent, which are or, after giving effect to
         the Refinancing, will be material, individually or in the aggregate, to
         the Company and its subsidiaries, taken as a whole, nor entered into
         any transaction not in the ordinary course of business, (B) there has
         not been any change or development which, singly or in the aggregate,
         could reasonably be expected to result in a Material Adverse Effect and
         (C) there has been no dividend or distribution of any kind declared,
         paid or made by the Issuers on any class of their capital stock other
         than Tax Distributions (as 




                                       14

<PAGE>   16

         defined in the Offering Memorandum).

                  (xliv) None of the execution, delivery and performance of this
         Agreement, the issuance and sale of the Notes, the issuance of the
         Guarantees, the application of the proceeds from the issuance and sale
         of the Notes and the consummation of the transactions contemplated
         thereby as set forth in the Offering Memorandum, will violate
         Regulations G, T, U or X promulgated by the Board of Governors of the
         Federal Reserve System or analogous foreign laws and regulations.

                  (xlv) The accountants who have certified or will certify the
         financial statements included or to be included as part of the Offering
         Memorandum were, as of the respective dates of their reports,
         independent accountants as required by the Act. The historical
         financial statements of the Company, together with related schedules
         and notes thereto, comply as to form in all material respects with the
         requirements applicable to registration statements on Form S-1 under
         the Act and present fairly in all material respects the financial
         position and results of operations of the Company and its subsidiaries
         at the dates and for the periods indicated. Such financial statements
         have been prepared in accordance with generally accepted accounting
         principles applied on a consistent basis throughout the periods
         presented. The pro forma financial statements included in the Offering
         Memorandum have been prepared on a basis consistent with such
         historical statements of the Company, except for the pro forma
         adjustments specified therein, and give effect to assumptions made on a
         reasonable basis and present fairly in all material respects the
         historical and proposed transactions contemplated by this Agreement and
         the other Operative Documents; and such pro forma financial statements
         comply as to form in all material respects with the requirements
         applicable to pro forma financial statements included in registration
         statements on Form S-1 under the Act, except as expressly stated
         therein. The other financial and statistical information and data
         included in the Offering Memorandum derived from the historical and pro
         forma financial statements, are accurately presented in all material
         respects and prepared on a basis consistent with the financial
         statements, historical and pro forma, included in the Offering
         Memorandum and the books and records of the Company and its
         subsidiaries.

                  (xlvi) None of the Issuers intends to, nor does it believe
         that it will, incur debts beyond its ability to pay such debts as they
         mature. The present fair saleable value of the assets of each of the
         Issuers exceeds the amount that will be required to be paid on or in
         respect of its existing debts and other liabilities (including
         contingent liabilities) as they become absolute and matured. The assets
         of each of the Issuers do not constitute unreasonably small capital to
         carry out its business as conducted or as proposed to be conducted.
         Upon the issuance of the Notes and consummation of the Refinancing, the
         present fair saleable value of the assets of each of the Issuers will
         exceed the amount that will be required to be paid on or in respect of
         its existing debts and other liabilities (including contingent
         liabilities) as they become absolute and matured. Upon the issuance of
         the Notes and the consummation of the Refinancing, the assets of each
         of the Issuers will not constitute unreasonably small capital to carry
         out its business as now conducted, including the capital needs of each
         of the Issuers, taking into account the projected capital requirements
         and capital availability.

                  (xlvii) Except pursuant to this Agreement, there are no
         contracts, agreements or understandings between the Company and its
         subsidiaries and any other person that would give rise to a valid claim
         against the Company or any of its subsidiaries or the Initial Purchaser
         for a brokerage commission, finder's fee or like payment in connection
         with the issuance, purchase and sale of the Notes or the issuance of
         the Guarantees.

                  (xlviii) There exist no conditions that would constitute a
         default (or an event which with 



                                       15


<PAGE>   17

         notice or the lapse of time, or both, would constitute a default) under
         any of the Operative Documents.

                  (xlix) Each of the Company and its subsidiaries, to their
         knowledge, has complied with all of the provisions of Florida H.B.
         1771, codified as Section 517.075 of the Florida statutes, and the
         Company and its subsidiaries are not doing business with the Government
         of Cuba or with any person or any affiliate located in Cuba.

                  (l) Each certificate signed by any officer of the Issuers or
         any of the Guarantors and delivered to the Initial Purchaser or counsel
         for the Initial Purchaser shall be deemed to be a representation and
         warranty by such Issuer or such Guarantor, as the case may be, to the
         Initial Purchaser as to the matters covered thereby.

                  The Issuers acknowledge that the Initial Purchaser and, for
purposes of the opinions to be delivered to the Initial Purchaser pursuant to
Section 8 hereof, counsel for the Issuers and counsel for the Initial Purchaser,
will rely upon the accuracy and truth of the foregoing representations and
hereby consent to such reliance.

         (b) The Initial Purchaser represents, warrants and covenants to the 
Issuers and agrees that:

                  (i) Such Initial Purchaser is a QIB, with such knowledge and
         experience in financial and business matters as are necessary in order
         to evaluate the merits and risks of an investment in the Series A
         Notes.

                  (ii) Such Initial Purchaser (A) is not acquiring the Series A
         Notes with a view to any distribution thereof that would violate the
         Act or the securities laws of any state of the United States or any
         other applicable jurisdiction and (B) will be reoffering and reselling
         the Series A Notes only to QIBs in reliance on the exemption from the
         registration requirements of the Act provided by Rule 144A, to
         Accredited Investors in a private placement exempt from the
         registration requirements of the Act and in offshore transactions in
         reliance upon Regulation S under the Act.

                  (iii) No form of general solicitation or general advertising
         (within the meaning of Regulation D under the Act) has been or will be
         used by such Initial Purchaser or any of its representatives in
         connection with the offer and sale of any of the Series A Notes,
         including, but not limited to, articles, notices or other
         communications published in any newspaper, magazine, or similar medium
         or broadcast over television or radio, or any seminar or meeting whose
         attendees have been invited by any general solicitation or general
         advertising.

                  (iv) The Initial Purchaser agrees that, in connection with the
         Exempt Resales, it will solicit offers to buy the Series A Notes only
         from, and will offer to sell the Series A Notes only to, Eligible
         Purchasers. The Initial Purchaser further (A) agrees that it will offer
         to sell the Series A Notes only to, and will solicit offers to buy the
         Series A Notes only from (1) Eligible Purchasers that the Initial
         Purchaser reasonably believes are QIBs, (2) Accredited Investors who
         make the representations contained in, and execute and return to the
         Initial Purchaser, a certificate in the form of ANNEX A attached to the
         Offering Memorandum and (3) Reg S Investors, (B) in the case of such
         QIBs, such Accredited Investors and such Reg S Investors, acknowledges
         and agrees that such Series A Notes will not have been registered under
         the Act and may be resold, pledged or otherwise transferred only (x)(I)
         to a person whom the seller reasonably believes is a QIB purchasing for
         its own account or for the account of a QIB in a transaction meeting
         the

         requirements of Rule 144A, (II) in an offshore transaction (as defined
         in Rule 902 under the Act) meeting the requirements of Rule 904 under
         the Act, (III) in a transaction meeting the requirements of Rule 144
         under the Act, (IV) to an Accredited Investor that, prior to such
         transfer, furnishes the Initial Purchaser a signed letter containing
         certain representations and agreements relating to the registration of
         transfer of such Series A Notes (the form of which is substantially the
         same as ANNEX A to the Offering Memorandum) and, if such transfer is in
         respect of an aggregate principal amount of Series A Notes less than
         $250,000, an opinion of counsel acceptable to the Issuers that such
         transfer is in compliance with the Act or (V) in accordance with
         another exemption from the registration requirements of the Act (and
         based upon an opinion of counsel if the Issuers so request), (y) to the
         Issuers, (z) pursuant to an effective registration statement under the
         Act and, in each case, in accordance with any applicable securities
         laws of any state of the United States or any other applicable
         jurisdiction and (C) acknowledges that it will, and will notify each
         subsequent holder that it is required to, notify any purchaser of the
         security evidenced thereby of the resale restrictions set forth in (B)
         above.

                  (v) Such Initial Purchaser agrees that it has offered the
         Series A Notes and will offer and sell the Series A Notes (A) as part
         of its distribution at any time and (B) otherwise until 40 days after
         the later of the commencement of the offering of the Series A Notes
         pursuant hereto and the Closing Date, only in accordance with Rule 903
         of Regulation S or another exemption from the registration requirements
         of the Act. Such Initial Purchaser agrees that, during such 40-day
         restricted period, it will not cause any advertisement with respect to
         the Series A Notes (including any "tombstone advertisement") to be
         published in any newspaper or periodical or posted in any public place
         and will not issue any circular relating to the Series A Notes, except
         such advertisements as are permitted by and include the statements
         required by Regulation S.

                  (vi) Such Initial Purchaser agrees that it has not offered or
         sold and will not offer or sell the Series A Notes sold pursuant hereto
         in reliance on Regulation S (A) as part of its distribution at any time
         and (B) otherwise until 40 days after the later of the commencement of
         the offering of the Series A Notes pursuant hereto and the Closing
         Date, to a U.S. person (as defined in Rule 902 of the Act) or for the
         account or benefit of a U.S. person (other than a distributor (as
         defined in Rule 902 of the Act)).

                  (vii) Such Initial Purchaser agrees that, at or prior to
         confirmation of a sale of Series A Notes by it to any distributor,
         dealer or person receiving a selling concession, fee or other
         remuneration during the 40-day restricted period referred to in Rule
         903(c)(3) under the Act, it will send to such distributor, dealer or
         person receiving a selling concession, fee or other remuneration a
         confirmation or notice to substantially the following effect:

                           "The Series A Notes covered hereby have not been
                           registered under the U.S. Securities Act of 1933, as
                           amended (the "Securities Act"), and may not be
                           offered and sold within the United States or to, or
                           for the account or benefit of, U.S. persons (i) as
                           part of your distribution at any time or (ii)
                           otherwise until 40 days after the later of the
                           commencement of the offering and the Closing Date,
                           except in either case in accordance with Regulation S
                           under the Act (or Rule 144A or to Accredited
                           Investors in transactions that are exempt from the
                           registration requirements of the Act), and in
                           connection with any subsequent sale by you of the
                           Series A Notes covered hereby in reliance on
                           Regulation S during the period referred to above to
                           any distributor, dealer or person receiving a selling
                           concession, fee or other remuneration, you must
                           deliver a notice to substantially the foregoing
                           effect. Terms used above have the meanings assigned

                           to them in Regulation S."

                  (viii) Such Initial Purchaser agrees that the Series A Notes
         offered and sold in reliance on Regulation S will be represented upon
         issuance by a global security that may not be exchanged for definitive
         securities until the expiration of the 40-day restricted period
         referred to in Rule 903(c)(3) of the Act and only upon certification of
         beneficial ownership of such Series A Notes by non-U.S. persons or U.S.
         persons who purchased such Series A Notes in transactions that were
         exempt from the registration requirements of the Act.

                  The Initial Purchaser understands that the Issuers and, for
purposes of the opinions to be delivered to the Initial Purchaser pursuant to
Section 8 hereof, counsel for the Issuers and counsel for the Initial Purchaser
will rely upon the accuracy and truth of the foregoing representations and
hereby consents to such reliance.

         6.       INDEMNIFICATION.

                  (a) The Issuers agree, and will cause the Guarantors to agree,
         to indemnify and hold harmless (i) the Initial Purchaser, (ii) each
         person, if any, who controls the Initial Purchaser within the meaning
         of Section 15 of the Act or Section 20(a) of the Exchange Act and (iii)
         the officers, directors, partners, employees, representatives and
         agents of the Initial Purchaser or any controlling person to the
         fullest extent lawful, from and against any and all losses,
         liabilities, claims, damages and expenses whatsoever (including but not
         limited to reasonable attorneys' fees and any and all expenses
         whatsoever incurred in investigating, preparing or defending against
         any investigation or litigation, commenced or threatened, or any claim
         whatsoever, and any and all amounts paid in settlement of any claim or
         litigation), joint or several, to which they or any of them may become
         subject under the Act, the Exchange Act or otherwise, insofar as such
         losses, liabilities, claims, damages or expenses (or actions in respect
         thereof) arise out of or are based upon any untrue statement or alleged
         untrue statement of a material fact contained in the Preliminary
         Offering Memorandum or the Offering Memorandum, or in any supplement
         thereto or amendment thereof, or arise out of or are based upon the
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; provided, however, that the Issuers and the Guarantors will
         not be liable in any such case to the extent, but only to the extent,
         that any such loss, liability, claim, damage or expense arises out of
         or is based upon any such untrue statement or alleged untrue statement
         or omission or alleged omission made therein in reliance upon and in
         conformity with information relating to the Initial Purchaser furnished
         to the Issuers in writing by or on behalf of the Initial Purchaser
         expressly for use therein. This indemnity agreement will be in addition
         to any liability which the Issuers and the Guarantors may otherwise
         have, including under this Agreement.

                  (b) The Initial Purchaser agrees to indemnify and hold
         harmless (i) the Issuers and the Guarantors, (ii) each person, if any,
         who controls any of the Issuers and the Guarantors within the meaning
         of Section 15 of the Act or Section 20(a) of the Exchange Act, and
         (iii) the respective officers, directors, trustees, partners,
         employees, representatives and agents of the Issuers and the
         Guarantors, or any controlling person, against any losses, liabilities,
         claims, damages and expenses whatsoever (including but not limited to
         reasonable attorneys' fees and any and all expenses whatsoever incurred
         in investigating, preparing or defending against any investigation or
         litigation, commenced or threatened, or any claim whatsoever and any
         and all amounts paid in settlement of any claim or litigation), joint
         or several, to which they or any of them may become subject under the
         Act, the Exchange Act or otherwise, insofar as such losses,
         liabilities, claims, 



                                       18


<PAGE>   20
         damages or expenses (or actions in respect thereof) arise out of or are
         based upon any untrue statement or alleged untrue statement of a
         material fact contained in the Preliminary Offering Memorandum or the
         Offering Memorandum, or in any amendment thereof or supplement thereto,
         or arise out of or are based upon the omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, in each case
         to the extent, but only to the extent, that any such loss, liability,
         claim, damage or expense arises out of or is based upon any untrue
         statement or alleged untrue statement or omission or alleged omission
         made therein in reliance upon and in conformity with information
         relating to the Initial Purchaser furnished to the Issuers in writing
         by or on behalf of the Initial Purchaser expressly for use therein;
         provided, however, that in no case shall the Initial Purchaser be
         liable or responsible for any amount in excess of the discounts and
         commissions received by the Initial Purchaser, as set forth on the
         cover page of the Offering Memorandum. This indemnity will be in
         addition to any liability which the Initial Purchaser may otherwise
         have, including under this Agreement.

                  (c) Promptly after receipt by an indemnified party under
         subsection (a) or (b) above of notice of the commencement of any
         action, such indemnified party shall, if a claim in respect thereof is
         to be made against the indemnifying party under such subsection, notify
         each party against whom indemnification is to be sought in writing of
         the commencement thereof (but the failure so to notify an indemnifying
         party shall not relieve it from any liability which it may have under
         this Section 6 except to the extent that it has been prejudiced in any
         material respect by such failure or from any liability which it may
         otherwise have). In case any such action is brought against any
         indemnified party, and it notifies an indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate therein, and to the extent it may elect by written notice
         delivered to the indemnified party promptly after receiving the
         aforesaid notice from such indemnified party, to assume the defense
         thereof with counsel reasonably satisfactory to such indemnified party.
         Notwithstanding the foregoing, the indemnified party or parties shall
         have the right to employ its or their own counsel in any such case, but
         the fees and expenses of such counsel shall be at the expense of such
         indemnified party or parties unless (i) the employment of such counsel
         shall have been authorized in writing by the indemnifying parties in
         connection with the defense of such action, (ii) the indemnifying
         parties shall not have employed counsel to take charge of the defense
         of such action within a reasonable time after notice of commencement of
         the action, or (iii) such indemnified party or parties shall have
         reasonably concluded, based upon the advice of counsel, that there may
         be defenses available to it or them which are different from or
         additional to those available to one or all of the indemnifying parties
         (in which case the indemnifying party or parties shall not have the
         right to direct the defense of such action on behalf of the indemnified
         party or parties), in any of which events such fees and expenses of
         counsel shall be borne by the indemnifying parties; provided, however,
         that the indemnifying party under subsection (a) or (b) above shall
         only be liable for the legal expenses of one counsel (in addition to
         any local counsel) for all indemnified parties in each jurisdiction in
         which any claim or action is brought. Anything in this subsection to
         the contrary notwithstanding, an indemnifying party shall not be liable
         for any settlement of any claim or action effected without its prior
         written consent, provided that such consent was not unreasonably
         withheld.

         7.       CONTRIBUTION. In order to provide for contribution in
circumstances in which the indemnification provided for in Section 6 is for any
reason held to be unavailable from the Issuers and the Guarantors or is
insufficient to hold harmless a party indemnified thereunder, the Issuers and
the Guarantors, on the one hand, and the Initial Purchaser, on the other hand,
shall contribute to the aggregate losses, claims, damages, liabilities and
expenses of the nature contemplated by such indemnification provision (including
any investigation, legal and other expenses incurred in connection with, and any



                                       19


<PAGE>   21

amount paid in settlement of, any action, suit or proceeding or any claims
asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Issuers and the Guarantors, any
contribution received by the Issuers and the Guarantors from persons, other than
the Initial Purchaser, who may also be liable for contribution, including
persons who control the Issuers and the Guarantors within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act) to which the Issuers, the
Guarantors and the Initial Purchaser may be subject, in such proportion as is
appropriate to reflect the relative benefits received by the Issuers and the
Guarantors, on one hand, and the Initial Purchaser, on the other hand, from the
offering of the Series A Notes or, if such allocation is not permitted by
applicable law or indemnification is not available as a result of the
indemnifying party not having received notice as provided in Section 6, in such
proportion as is appropriate to reflect not only the relative benefits referred
to above but also the relative fault of the Issuers and the Guarantors, on one
hand, and the Initial Purchaser, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Issuers and the Guarantors, on one hand,
and the Initial Purchaser, on the other hand, shall be deemed to be in the same
proportion as (i) the total proceeds from the offering of Series A Notes (net of
discounts but before deducting expenses) received by the Issuers and the
Guarantors and (ii) the discounts and commissions received by the Initial
Purchaser, respectively, in each case as set forth in the table on the cover
page of the Offering Memorandum. The relative fault of the Issuers and the
Guarantors, on one hand, and of the Initial Purchaser, on the other hand, 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 Issuers, the Guarantors
or the Initial Purchaser and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Issuers, the Guarantors and the Initial Purchaser agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined by
pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to above. Notwithstanding the
provisions of this Section 7, (i) in no case shall the Initial Purchaser be
required to contribute any amount in excess of the amount by which the discounts
and commissions applicable to the Series A Notes purchased by the Initial
Purchaser pursuant to this Agreement exceeds the amount of any damages which the
Initial Purchaser has otherwise been required to pay by reason of any untrue or
alleged untrue statement or omission or alleged omission and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section 7, (A) each
person, if any, who controls the Initial Purchaser within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act and (B) the officers,
directors, partners, employees, representatives and agents of the Initial
Purchaser or any controlling person shall have the same rights to contribution
as the Initial Purchaser, and (A) each person, if any, who controls any of the
Issuers and the Guarantors within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and (B) the respective officers, directors,
trustees, partners, employees, representatives and agents of the Issuers and the
Guarantors shall have the same rights to contribution as the Issuers and the
Guarantors, subject in each case to clauses (i) and (ii) of this Section 7. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties
under this Section 7, notify such party or parties from whom contribution may be
sought, but the failure to so notify such party or parties shall not relieve the
party or parties from whom contribution may be sought from any obligation it or
they may have under this Section 7 or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without its prior
written consent, provided that such written consent was not unreasonably
withheld.

         8.       CONDITIONS OF INITIAL PURCHASER'S OBLIGATIONS. The obligations
of the Initial Purchaser to purchase and pay for the Series A Notes, as provided
herein, shall be subject to the satisfaction of the

         force and effect as if made on and as of the date hereof and the
         Closing Date, respectively. Each of the Issuers shall have performed or

         York City time, on the second business day following the date of this
         Agreement or at such later date and time as to which the Initial
         Purchaser may agree, and no stop order suspending the qualification or
         exemption from qualification of the Series A Notes in any jurisdiction

         governmental agency which would, as of the Closing Date, prevent the
         issuance of the Series A Notes or the Guarantees or the consummation of
         the Refinancing; no action, suit or proceeding shall have been
         commenced and be pending against or affecting or, to the best knowledge
         of the Issuers, threatened against, the Company or any of its
         subsidiaries before any court or arbitrator or any governmental body,
         agency or official that, if adversely determined, could reasonably be
         expected to prevent the issuance of the Series A Notes or the
         Guarantees or the consummation of the Refinancing; and no stop order
         shall have been issued preventing the use of the Offering Memorandum,
         or any amendment or supplement thereto, or which could reasonably be
         expected to have a Material Adverse Effect.

         Offering Memorandum, (i) there shall not have been any material adverse
         change, or any development that is reasonably likely to result in a
         material adverse change, in the capital stock or the long-term debt, or
         material increase in the short-term debt, of the Company or any of its
         subsidiaries from that set forth in the Offering Memorandum, (ii) no

         Company or any of its subsidiaries shall have incurred any liabilities
         or obligations, direct or contingent, that are or, after giving effect
         to the Refinancing, will be material, individually or in the aggregate,
         to the Company and its subsidiaries, taken as a whole, and that are
         required to be disclosed on a balance sheet or notes thereto in
         accordance with generally accepted accounting principles and are not
         disclosed on the latest balance sheet or notes thereto included in the
         Offering Memorandum. Since the date hereof and since the dates as of
         which information is given in the Offering Memorandum, there shall not
         have occurred any material adverse change in the business, prospects,
         financial condition or results of operation of the Company and its
         subsidiaries, taken as a whole.

                  (e) The Initial Purchaser shall have received certificates,

         Initial Purchaser's judgment, makes it inadvisable or impracticable to
         proceed with the delivery of the Series A Notes as contemplated hereby.

                  (c) Any notice of termination pursuant to this Section 11
         shall be by telephone or telephonic facsimile and, in either case,
         confirmed in writing by letter.

                  (d) If this Agreement shall be terminated pursuant to any of
         the provisions hereof (otherwise than pursuant to clause (iv) of
         Section 11(b), in which case each party will be responsible for its own
         expenses), or if the sale of the Series A Notes provided for herein is
         not consummated because any condition to the obligations of the Initial
         Purchaser set forth herein is not satisfied or because of any refusal,
         inability or failure on the part of either of the Issuers to perform
         any agreement herein or comply with any provision hereof, the Issuers
         shall reimburse the Initial Purchaser for all out-of-pocket expenses
         (including the reasonable fees and expenses of the Initial Purchaser's
         counsel), incurred by the Initial Purchaser in connection herewith.

                       ARTICLE IV - Powers of the Trustees

         Except as herein otherwise expressly provided, the Trustees in general
shall have the power to deal with the trust property as if they were the
absolute owners thereof free of all trusts and to take any other action that
they may deem beneficial to the Trust. Without limiting the generality of the
foregoing, they shall also have the following powers:

         A. To purchase or otherwise acquire and to hold, develop, improve, and
manage any real or personal property; to invest any of the trust property in
such manner as they may deem advisable without being limited as to the kind or
amount of any investment; to sell, exchange or otherwise dispose of and convey
any real or personal property or any interest therein for such considerations
and upon such terms and conditions as they may deem advisable; to participate in
loans; to be a joint venturer; to be a partner; to join with others in the
acquisition or development of real or personal property or any interest therein;
to borrow money or acquire assets on a purchase money loan basis, and to issue
bonds, notes or other evidences of indebtedness, and to secure the same by
mortgage or pledge of all or any part of the trust assets, provided that any
such obligations shall bind the trust property only, and not the Trustees or
shareholders individually; to lend money without or with security; to guarantee
the obligations of others; to execute leases as lessor or as lessee, including
leases for terms expiring after the expiration of the Trust; to hold any
property or any interest in property in the name of agents or nominees without

into by the Trustees with respect to the trust estate.

         B. To prosecute, compromise, submit to arbitration, or abandon any
claim or dispute involving the trust property or assets and pay all debts,
expenses or claims against them upon such evidence as they deem proper.

         C. To adopt by-laws and rules in the nature of by-laws for the
administration of the Trust and to change the same from time to time; and such
by-laws or rules shall control the action of the Trust while in effect, but no
person dealing with the Trust or the Trustees need inquire as to the existence
of the same or compliance therewith, but may rely completely upon this Trust
instrument as amended in accordance with the provisions hereof or upon any
certificate as hereinafter provided.

         D. To deposit moneys of the Trust in any bank or trust company, or with
any bankers, and to entrust to any bank or banker, trust company or safe deposit
company for safekeeping any of the securities and any documents and papers

other professional advisers, any of whom may, but need not be, a Trustee or
officer. To delegate to any of the officers, agents, employees, or to one or

or employee.

         F. Any Trustee may by an instrument in writing grant to any other
Trustee the power and authority to exercise on behalf of the Trust any of the
powers, authority and discretion of such grantor Trustee hereunder, so that
while said delegation is in effect the Trustee to whom such powers, authority
and discretion are granted may exercise the same as if he were acting in the
capacity of Trustee in place and stead of such grantor in addition to acting as
Trustee in his own capacity; and in the event of such grant, the grantee Trustee
shall, in all matters requiring or permitting the vote of the Trustees, have one
vote in his own capacity and one vote as grantee of each Trustee who has made
such grant of powers, authority, and discretion to him. G. The Trustees may
determine reasonable compensation for themselves as Trustees and also the
compensation of any officer, employee or agent of the Trust.

than seven Trustees shall be permitted. No Trustee shall be required to be a
shareholder, nor to give bond or surety in any form.

acknowledged by such Trustee and such resignation shall become effective when

a majority of the voting shares entitled to vote on the matter. Any such
appointment shall become effective upon written acceptance of the office by the
new Trustee. Upon the appointment of any successor Trustee, title to the trust
estate shall thereupon without any conveyance vest in said succeeding Trustee
jointly with the remaining Trustee or Trustees, if any.

         D. Any Trustee may be removed by the holders of a majority of the
voting shares entitled to vote in the election of a Trustee to fill the vacancy.
Any such removal shall be effective forthwith upon such action being taken.

         E. Except as otherwise expressly provided in this instrument, any
action or vote taken by or any decision made by the Trustees shall be by a
majority of the then Trustees. No meeting, formal or informal, shall be required
for them to act.

contracts, releases, notes, partial releases, discharges, subordination
agreements, checks, drafts, securities, assignments, endorsements, and proxies)
may be signed, sealed, executed, acknowledged, and delivered on behalf of the
Trust by such Trustee or Trustees, officer or agent as "hall be authorized by
action or vote of the Trustee. All instruments, documents, and papers either
executed as aforesaid, accompanied by a certificate as set forth in Paragraph B
of Article VII, or executed by a majority of the Trustees, shall be conclusive
evidence in favor of every person relying thereon or claiming thereunder at the
time of the delivery thereof that this Trust was in full force and effect and
that the person or persons executing such instrument were duly authorized to
execute and deliver the same and that the execution and delivery thereof were in
every respect binding upon the Trustees and the Trust.

         B. All agreements, obligations, instruments, papers, and actions by or
in the name and behalf of this Trust shall be made, incurred, executed, signed
or taken by or in the name of the Trust, and shall, in such cases and in such
manner as the Trustees deem advisable, expressly exempt the Trustees and
shareholders from personal liability and expressly provide that the trust
property alone shall be liable thereunder or by reason thereof.

         C. The Trustees may from time to time adopt and use a form of seal for
this Trust, forms for certificates representing shares hereunder, and such other
forms as they deem appropriate.

             ARTICLE VII - Protection of Persons Dealing with Trust

         A. No corporation, person, or transfer agent shall be held to examine
into the trust hereunder, but such corporation, person, or transfer agent may
deal with trust property as if the Trustees were the owners thereof free of all
trusts; and no such corporation, person, or transfer agent dealing with the
Trustees shall be required to see to the application of any money or property
paid or delivered to any Trustee or agent of the Trustees.

         B. A certificate signed by any one Trustee or the Secretary certifying
as to who are the Trustees for the time being, or as to any action by the
Trustees or shareholders, or as to any other fact affecting or relating to the
Trust or the trust instrument, may be treated as conclusive evidence thereof by

member, trustee, director, officer, beneficiary, shareholder, agent, fiduciary,

             ARTICLE VIII - Protection of Trustees and Shareholders

         A. A Trust, and not a partnership, is created by this Declaration. The
relationship of the shareholders to the Trustees is solely that of cestuis que
trust, and neither the shareholders nor the Trustees are partners.

         B. No shareholder shall be personally liable for any obligation or
liability incurred by this Trust or by the Trustees, and the Trustees shall have
no right of indemnity or exoneration against the shareholders in respect
thereof.


         C. Subject to Paragraph F of this Article, no Trustee shall be
personally liable for any obligation or liability incurred by this Trust or by
the Trustees, and each Trustee shall be entitled to reimbursement and
exoneration out of the trust estate according to law.

         D. The trust estate alone shall be liable for the payment or
satisfaction of all obligations and liabilities incurred in carrying on the
affairs of this Trust.

         E. Proceedings against this Trust may be brought against the Trustees
as Trustee" hereunder but not personally. The Trustees shall be parties thereto
only insofar as necessary to enable such obligation or liability to be enforced
against the trust estate.

         F. No Trustee shall be liable to this Trust or the shareholders except
for his own acts, neglects and defaults in bad faith.

                      ARTICLE IX - Shares and Shareholders

         A. The beneficial interests hereunder shall be represented by such
shares as the Trustees may determine. The shares may be preferred shares or
common shares or both, and may be issued in any number of classes and, within
each class, in one or more series, all as the Trustees may determine. The
Trustees are authorized to fix the designations, preferences, privileges, and
voting powers of the shares of each such class and series and the restrictions
or qualifications thereof. Without limiting the generality of the foregoing, the
Trustees may fix the number of shares to constitute each class and series, which
number may from time to time be increased or decreased, and the distinctive
designations thereof; the dividend rate on the shares and whether the dividends
shall be cumulative or non-cumulative; whether or not the shares or a class or
series shall be redeemable and, if redeemable, all of the terms and conditions
of redemption; the conversion rights, if any, of any class or series, as well as
provisions for adjustment of the conversion rate, in such events as the Trustees
shall determine; the amount per share payable on the shares of each class and
series upon voluntary or involuntary liquidation, dissolution, or winding up of
the trust; the voting rights of each class and series; the restrictions, if any,
on the transfer of the shares of any class or series; and such other terms and
conditions as the Trustees may determine.

         B. The number of shares which the Trustees may authorize shall be
unlimited. The Trustees from time to time may issue such shares, including
fractional shares, upon such terms and conditions, in such amounts, to such
persons, at such times, and for such consideration as they may 

                                      -5-
<PAGE>   6
from time to time deem appropriate. No holder of any class or series of shares
shall be entitled to subscribe for any additional shares of such class or series
or any other class or series unless the Trustees shall otherwise determine.

         C. Except as specifically otherwise provided in this instrument as it
may from time to time be amended, or as the Trustees may from time to time
determine under Paragraph A above, the holders of voting common shares shall
have exclusive voting power on any matter on which the vote or consent of
shareholders is authorized or required to be given under the terms hereof. No
amendment of this Declaration of Trust may be made nor shall the Trustees take
any action which modifies and adversely affects the rights of holders of any
class or series of shares except with the written assent of the holders of a
majority of the outstanding shares of such class or series.

         D. Each shareholder shall be entitled to a certificate signed by a
Trustee, and the Secretary or an assistant Secretary, if there be such officers.

         E. Shares shall be transferable only on the books of the Trust by
assignment in writing by the person entitled to make such transfer hereunder or
his agent or legal representative, upon surrender and cancellation of the
certificate or certificates therefor. The Trustees may treat the holder of
record for all purposes as the owner of the share or shares standing in his
name.

         F. Shareholders, insofar as action by them is required or permitted,
may act with or without a meeting and may act either personally or through their
agent or proxies or through their guardians or other legal representatives. The
holders of majority of the shares of any class or series shall constitute a
quorum at any meeting of such class or series.

         G. Meetings of shareholders may be called by any Trustee, or by any
shareholder owning at least ten percent (10%) of any class or series of shares.
A written notice stating the time, place and purposes of the meeting shall be
mailed to all shareholders at least three days before such meeting by the person
calling such meeting or by the Trustees. Any shareholder may by writing waive
notice of any meeting, assent to the record thereof after the meeting, and give
proxies, and any one of such procedures or combination thereof shall have the
same effect as if the shareholders attended the meeting and voted his shares
there. Any action to be taken by shareholders may be taken without a meeting if
authorized by all shareholders entitled to vote on the matter by a writing
signed by such shareholders and delivered to the secretary for filing with the
records of meetings of shareholders. Promptly upon the receipt of any such
signed authorization, the secretary shall file same with the appropriate
records.
                             ARTICLE X - Termination

         This Trust shall terminate upon the expiration of twenty (20) years
after the death of the last to die of all of the original Trustees, their
present spouses and their issue now living, and may be sooner terminated by vote
of, or by an instrument or instruments in writing signed by a majority of the
Trustees and by the holders of a majority of each class and series of the voting
shares outstanding. Upon the termination of the Trust, subject to the payment or
making provision for the payment of all obligations and liabilities of the Trust
and the Trustees and payment to the holders of preferred shares, if any, the net
assets of the Trust shall be distributed among the holders of the common shares,
on a share for share basis except as may be otherwise provided in the

                                      -6-
<PAGE>   7
authorizations creating the classes and series of shares. In making any such
distribution, the Trustees may sell all or any portion of the trust property and
distribute the net proceeds thereof, or they may distribute any of the assets or
undivided interests therein in kind, at such valuations as they may deem to be
fair, their determination to be conclusive upon all parties. Upon termination of
the Trust, the foregoing powers shall be deemed to include the power to transfer
the trust property or any portion thereof to any association, trust or
corporation in exchange for securities of the association, trust or corporation
and for the purpose of distributing the securities so received to shareholders
in the manner above set forth. In making any transfer pursuant to distribution,
they may make such transfer subject to any or all of the liabilities of the
Trust or on condition of the shareholders assuming in a manner satisfactory to
the Trustees the obligation to pay and discharge the obligations and liabilities
of the Trust. The powers of the Trustees shall continue until the affairs of the
Trust have been wound up.

                             ARTICLE XI - Recording

         The Trustees may record this instrument in any Registry of Deeds or
Land Court Registry in the Commonwealth of Massachusetts. If they so record, all
amendments to this Trust and all changes of persons constituting the Trustees
from time to time shall be recorded in the Registry where this Trust is first
recorded. This Trust shall first be recorded in Middlesex (South) Registry of
Deeds. If they so record, any person dealing with the Trustees of any of them or
the trust property, may assume without further inquiry that there has been
recorded or filed in said Registry notice of all amendments of or additions to
the trust instrument, of any resignation, removals, appointments or other
changes of Trustees, or of any other matter affecting the terms or existence of
this Trust, and all such persons shall be fully protected in relying on the
state of the record in said Registry without further inquiry. Any person dealing
with the trust property or the Trustees or any of them may, however, without
resort to said Registry, always rely conclusively on a certificate as authorized
under Paragraph B of Article VII. The Trustee may record this instrument in any
other place they deem appropriate.

                            ARTICLE XII - Amendments

        The terms of this Declaration of Trust may from time to time be
amended, added to, or rescinded in any particular whatsoever by vote of, or by
a written instrument signed by one of the Trustees and assented to or approved
in writing by the holders opound sterling a majority of each class and series
of the outstanding voting shares. Such action shall become effective upon its
execution.

                                    100 Charles River Plaza

                  SIXTH: The Corporation is to have perpetual existence.

                  SEVENTH: For the management of the business and for the
conduct of the affairs of the Corporation, and in further definition,
limitation, and regulation of the powers of the Corporation and of its directors
and of its stockholders or any class thereof, as the case may be, it is further
provided:

                           1. No election of directors need be by written ballot
                  unless so provided in the By-Laws of the Corporation.

                           2. Whenever the Corporation shall be authorized to
                  issue only one class of stock, each outstanding share shall
                  entitle the holder thereof to notice of, and the right to vote
                  at, any meeting of stockholders. Whenever the Corporation
                  shall be authorized to issue more than one class of stock, no
                  outstanding share of any class of stock which is denied voting
                  power under the provisions of the Certificate of Incorporation
                  shall entitle the holder thereof to the right to vote at any
                  meeting of stockholders except as the provisions of the
                  General 




<PAGE>   2

                  Corporation Law of the State of Delaware shall otherwise
                  require; provided, that no share of any such class which is
                  otherwise denied voting power shall entitle the holder thereof
                  to vote upon the increase or decrease in the number of
                  authorized shares of said class.

                  EIGHTH:           LIABILITY OF DIRECTORS. No director shall be
personally liable to the Corporation or its stockholders for monetary damages
for breach of a fiduciary duty as a director; provided, however, that to the
extent required by the provisions of Section 102(b)(7) of the General
Corporation Law of the State of Delaware or any successor statute, or any other
laws of the State of Delaware, this provision 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 the General Corporation Law of the State of Delaware,
(iv) for any transaction from which the director derived an improper personal
benefit, or (v) for any act or omission occurring prior to the date when the
provision becomes effective. If the General Corporation Law of the State of
Delaware hereafter is amended to authorize the further elimination or limitation
on personal liability of directors, then the liability of a director of the
Corporation, in addition to the limitation on personal liability provided
herein, shall be limited to the fullest extent permitted by the amended General
Corporation Law of the State of Delaware. Any repeal or modification of this
Article Tenth by the stockholders of the Corporation shall be prospective only,
and shall not adversely affect any limitation on the personal liability of a
director of the Corporation existing at the time of such repeal or modification.

                  NINTH:            INDEMNIFICATION AND ADVANCEMENT OF EXPENSES.

                  9.1               INDEMNIFICATION. Each person who was or is
made a party or is threatened to be made a party to or is involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he, or a
person for whom he is the legal representative, is or was a director, officer or
employee of the Corporation or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, shall be indemnified by the Corporation to
the fullest extent permitted by the General Corporation Law of the State of
Delaware. Expenses (including attorneys' fees) incurred by an officer or
director in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the corporation as authorized by the General Corporation Law of the State of
Delaware. Such expenses (including attorneys' fees) incurred by other employees
and agents may be so paid upon such terms and conditions, if any, as the Board
of Directors deems appropriate.

                  9.2               NONEXCLUSIVITY. The rights of 
indemnification provided in this Article NINTH shall be in addition to any
rights to which any person may otherwise be entitled by law or under any By-law,
agreement, vote of stockholders or disinterested directors, or otherwise. Such
rights shall continue as to any person who has ceased to be a director, officer
or employee and shall inure to the benefit of his heirs, executors and
administrators, and shall be applied to proceedings 



                                       2

<PAGE>   3

commenced after the adoption hereof, whether arising from acts or omissions
occurring before or after the adoption hereof.

                  9.3               INSURANCE. The Corporation may purchase and 
maintain insurance to protect any persons against any liability or expense
asserted against or incurred by such person in connection with any proceeding,
whether or not the Corporation would have the power to indemnify such person
against such liability or expense by law or under this Article NINTH or
otherwise. The Corporation may create a trust fund, grant a security interest or
use other means (including, without limitation, a letter of credit) to insure
the payment of such sums as may become necessary to effect indemnification as
provided herein.

                  9.4               AMENDMENT. No amendment to or repeal of this
Article NINTH shall apply to or have any effect on the rights of any individual
referred to in this Article NINTH for or with respect to acts or omissions of
such individual occurring prior to such amendment or repeal.

                  TENTH: The power to amend, alter, or repeal the Bylaws of the
Corporation and to adopt new Bylaws may be exercised by the Board of Directors
or by the stockholders.

                  ELEVENTH: From time to time any of the provisions of this

an Assistant Clerk or by the officer or the Trustees calling the meeting.

2.3 NOTICE. It shall be sufficient notice to a Trustee of a special meeting to
send notice by mail at least forty-eight hours or by telegram at least
twenty-four hours before the meeting addressed to the Trustee at his or her
usual or last known business or residence address or to give notice to him or
her in person or by telephone at least twenty-four hours before the meeting.

taken without a meeting if a written consent thereto is signed by a majority of

                                    ARTICLE 3
                                 Indemnification

3.1 TRUSTEES, OFFICERS. ETC. The Trust shall indemnify each of its Trustees,
officers and duly appointed agents (including persons who serve at the Trust's
request as directors, officers or trustees of another organization in which the
Trust has any interest as a shareholder, creditor or otherwise) (each such
Trustee, officer, agent or person hereinafter referred to as a "Covered
Person") against all liabilities and expenses, including but not limited to
amounts paid in satisfaction of judgments, in compromise or as fines and
penalties, and counsel fees reasonably incurred by any Covered Person in
connection with the defense or disposition of any action, suit or other
proceeding, whether civil or criminal, before any court or administrative or
legislative body, in which such Covered Person may be or may have been involved
as a party or otherwise or with which such person may be or may have been
threatened, while in office or thereafter, by reason of any alleged act or
omission as a Trustee or officer or agent or by reason of his or her being or
having been such a Trustee or officer or agent, except with respect to any
matter as to which such Covered Person shall have been finally adjudicated in
any such action, suit or other proceeding not to have acted in good faith in the
reasonable belief that such Covered Person's action was in the best interest of
the Trust, and except that no Covered Person shall be indemnified against any
liability to the Trust or its Shareholders to which such Covered Person would
otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office. Expenses, including counsel fees so incurred by any
such Covered Person, may be paid from time to time by the Trust in advance of
the final disposition of any such action, suit or proceeding on the condition
that the amounts so paid shall be repaid to the Trust if it is ultimately
determined that indemnification of such expenses is not authorized under this
Article.


3.2 INDEMNIFICATION NOT EXCLUSIVE. The right of indemnification hereby provided
shall not be exclusive of or affect any other rights to which any such Covered
Person may be entitled. As used in this Article 4, the term "Covered Person"
shall include such person and his, her or its heirs, executors and
administrators. Nothing contained in this Article shall affect any rights to
indemnification to which personnel of the Trust, other than Trustees and
officers and agents, and other persons may be entitled by contract or otherwise
under law, or the power of the Trust to purchase and maintain liability
insurance on behalf of any such person.

3.3 AMENDMENT. No amendment to or repeal of this Article 3 shall apply to or
have any effect on the rights of any individual referred to in this Article 3
for or with respect to acts or omissions of such 


                                       2

individual occurring prior to such amendment or repeal.

                                     Reports

4.1 GENERAL. The Trustees and officers shall render reports at the time and in
the manner required by the Declaration of Trust or any applicable law. Officers
shall render such additional reports as they may deem desirable or from time to
time as may be required by the Trustees.


                                    ARTICLE 5
                                   Fiscal Year

                                    ARTICLE 6
                                      Seal

6.1 GENERAL. The seal of the Trust shall consist of a flatfaced die with the
word "Massachusetts", together with the name of the Trust and the year of its
organization cut or engraved thereon. Unless otherwise required by the Trustees,
it shall not be necessary to place the seal on, and its absence shall not impair
the validity of, any document, instrument or other paper executed and delivered
by or on behalf of the Trust.


                                    ARTICLE 7
                               Execution of Papers

7.1 GENERAL. Except as the Trustees, generally or in particular cases, may have
authorized the execution thereof in some other manner, all checks, notes, drafts
and other obligations and all registration statements and amendments thereto and
all reports and amendments thereto to the Securities and Exchange Commission
shall be signed by any of the Chief Executive Officer, any Vice-President, the
Treasurer or any of such other officers or agents as shall be designated for
that purpose by a vote of the Trustees.

                         Issuance of Share Certificates

8.1 SHARE CERTIFICATES. The Trustees may at any time authorize the issuance of
share certificates. In that event, each shareholder shall be entitled to a
certificate stating the number of shares owned by him or her, in such form as
shall be prescribed from time to time by the Trustees. Such 



                                       3


<PAGE>   4
certificates shall be signed by a Trustee, and the Secretary or Assistant
Secretary. Such signatures may be by facsimile if the certificate is signed by a
transfer agent, or by a registrar, other than a Trustee, officer or employee of
the Trust. In case any officer who has signed or whose facsimile signature has
been placed on such certificate shall cease to be such officer before such
certificate is issued, it may be issued by the Trust with the same effect as if
he or she were such officer at the time of its issue. In lieu of issuing
certificates for shares, the Trustees or the transfer agent may either issue
receipts therefor or may keep accounts upon the books of the trust for the
record holders of such shares, who shall in either case be deemed, for all
purposes hereunder, to be the holders of certificates for such shares as if they
had accepted such certificates and shall be held to have expressly assented and
agreed to the terms of this Article 8.

8.2 LOSS OF CERTIFICATES. In case of the alleged loss or destruction or the
mutilation of a share certificate, a duplicate certificate may be issued in
place thereof, upon such terms as the Trustees shall prescribe.

8.3 DISCONTINUANCE OF ISSUANCE OF CERTIFICATES. The Trustees may at any time
discontinue the issuance of share certificates and may, by written notice to
each shareholder, require the surrender of share certificates to the Trust for
cancellation. Such surrender and cancellation shall not effect the ownership of
shares in the Trust.


                                    ARTICLE 9
                    Shareholders' Voting Powers and Meetings

9.1 RECORD DATES. For the purpose of determining the shareholders who are
entitled to vote or act at any meeting or any adjournment thereof, or who are
entitled to receive payment of any dividend or of any other distribution, the
Trustees may from time to time fix a time, which shall be not more than 60 days
before the date of any meeting of shareholders or the date for the payment of
any dividend or of any other distribution, as the record date for determining
the shareholders having the right to notice of and to vote at such meeting and
any adjournment thereof or the right to receive such dividend or distribution,
and in such case only shareholders of record on such record date shall have such
right notwithstanding any transfer of shares on the books of the Trust after the
record date; or without fixing such record date the Trustees may for any of such
purposes close the register or transfer books for all or any part of such
period.


                                   ARTICLE 10

any purpose or purposes, may be called at any time by the Chairman of the Board
of Directors, the President, the Chief Executive Officer, or the Board of
Directors. A special meeting of the stockholders shall be called by the

when a specific item of business is required by law or by the Certificate of
Incorporation to be voted on separately by a class or series, a majority of the

either in person or by proxy, to constitute a quorum for the transaction of such
items of business. If, however, such quorum shall not be present or represented
at any meeting of stockholders, the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have the power to adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented. At such adjourned

adjournment, the Board of Directors shall fix a new record date for the
adjourned meeting, or the adjournment is for more than thirty (30) days, a
notice of such adjourned meeting shall be given as provided in Section 3.4 of

expiration of three (3) years from its date, unless a longer period is provided
for in the proxy. Unless and until voted, every proxy shall be revocable at the
pleasure of the person who executed it, or his legal representatives or assigns,
except in those cases where an irrevocable proxy permitted by statute has been
given.

         SECTION 3.9. STOCK RECORDS. The Secretary or agent having charge of the
stock transfer books shall make, at least ten (10) days before each meeting of
stockholders, a complete list of the stockholders entitled to vote at such
meeting or any adjournment thereof, arranged in alphabetical order and showing
the address of and the number and class and series, if any, of shares held by
each stockholder. Such list, for a period of ten (10) days prior to such
meeting, shall be kept at the principal place of business of the Corporation or

other places as required by statute and shall be subject to inspection by any
stockholder at any time during the meeting.

the Chairman of the Board of Directors, the President shall preside at all such
meetings. In the absence of the Chairman of the Board of Directors and the

Executive Officer are present, then any other director chosen by the directors
in attendance shall preside. The Secretary of the Corporation, or, in his or her
absence, an Assistant Secretary, if any, shall act as Secretary of every
meeting, but if neither the Secretary nor an Assistant Secretary is present, the
person presiding at the meeting shall appoint a Secretary of the meeting.

         SECTION 3.11. INSPECTORS AND JUDGES. The directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election or judges
of the vote, as the case may be, to act at the meeting or any adjournment
thereof. If an inspector or inspectors or judge or judges are not appointed, the
person presiding at the meeting may, but need not, appoint one or more
inspectors or judges. In case any person who may be appointed as an inspector or
judge fails to appear or act, the vacancy may be filled by appointment made by
the person presiding at the meeting. Each inspector or judge, if any, before
entering upon the discharge of his duties, shall take and sign an oath to
faithfully execute the duties of inspector or judge at such meeting with strict
impartiality and according to the best of his ability. The inspectors or judges,
if any, shall 



                                       3

<PAGE>   4

determine the number of shares of stock outstanding and the voting power of each
class and series, the shares of stock represented at the meeting, the existence
of a quorum, the validity and effect of proxies, and shall receive votes,
ballots or consents, hear and determine all challenges and questions arising in
connection with the right to vote, count and tabulate all votes, ballots or
consents, determine the result, and do such acts as are proper to conduct the
election or vote with fairness to all stockholders. On request of the person
presiding at the meeting, the inspector or inspectors or judge or judges, if
any, shall make a report in writing on any challenge, question or matter
determined by him or her or them and execute a certificate of any fact found by
him or her or them.

         SECTION 3.12. STOCKHOLDER PROPOSALS. At any annual meeting of the
stockholders, only such business shall be conducted as shall have been brought
before the meeting (a) by or at the direction of the Board of Directors or (b)
by any stockholder of the Corporation who is a stockholder of record at the time
of giving of the notice provided for in this Section 3.12, who shall be entitled
to vote at such meeting and who complies with the procedures set forth below.
For business to be properly brought before an annual meeting of stockholders,
the stockholder must have given timely notice thereof in writing to the
Secretary of the Corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
Corporation not less than sixty (60) days nor more than ninety (90) days prior
to the anniversary date of the immediately preceding annual meeting; provided,
however, that in the event that the annual meeting with respect to which such
notice is to be tendered is not held within thirty (30) days before or after
such anniversary date, notice by the stockholder to be timely must be received
no later than the close of business on the tenth (10th) day following the day on
which notice of the date of the meeting or public disclosure thereof was given
or made. Such stockholder's notice shall set forth as to each matter the
stockholder proposes to bring before the meeting (a) a brief description of the
business desired to be brought before the meeting and the reasons for conducting
such business at the meeting, (b) the name and address, as they appear on the
Corporation's books, of the stockholder proposing such business, (c) the class
and the number of shares of stock of the Corporation which are beneficially
owned by the stockholder and (d) a description of all arrangements or
understandings between such stockholder and any other person or persons
(including their names) in connection with such business and any material
interest of the stockholder in such business. Notwithstanding anything in these
By-laws to the contrary, no business shall be conducted at a stockholders
meeting except in accordance with the procedures set forth in this Section 3.12.
If the Board of Directors shall determine, based on the facts, that business was
not properly brought before the meeting in accordance with the procedures set
forth in this Section 3.12, the Chairman of the Board of Directors or the person
presiding at such meeting shall so declare to the meeting and any such business
not properly brought before such meeting shall not be transacted.
Notwithstanding the foregoing provisions of this Section 3.12, a stockholder
shall also comply with all applicable requirements of the Securities Exchange
Act of 1934, as amended, and the rules and regulations thereunder with respect
to the matters set forth in this Section 3.12. Notwithstanding the foregoing
provisions of this Section 3.12, stockholder nominations of persons for election
to the Board of Directors shall be governed by the Certificate of Incorporation.

director. When one or more directors shall resign from the board, effective at a
future date, a majority of the directors then in office, including those who
have resigned, shall have power to fill such vacancy or vacancies, the vote or
action by writing thereon to take effect when such resignation or resignations
shall become effective. The directors shall have and may exercise all their
powers notwithstanding the existence of one or more vacancies in their number,
subject to any requirements of law or of the Certificate of Incorporation or of
these By-Laws as to the number of directors required for a quorum or for any
vote or other actions.

meeting following any such determination shall be given to absent directors.
Other meetings of the Board of Directors may be held upon such notice or without
notice, and at such time and at such place as shall from time to time be
determined by the Board of Directors.

more of the Corporation's directors or officers are directors or officers, or

meeting of the Board or committee thereof which authorizes the contract or
transaction, or solely because his or their votes are counted for such purpose,

         Board of Directors or the committee, and the Board or committee in good
         faith authorizes the contract or transaction by the affirmative votes
         of a majority of the disinterested directors, even though the
         disinterested directors be less than a quorum; or

                  (2) The material facts as to his relationship or interest and
         as to the contract or transaction are disclosed or are known to the
         stockholders entitled to vote thereon, and the contract or transaction
         is specifically approved in good faith by vote of the stockholders; or

                  (3) The contract or transaction is fair as to the Corporation
         as of the time it is authorized, approved or ratified, by the Board of
         Directors, a committee thereof, or the stockholders.

         (b)      Common or interested directors may be counted in determining

         SECTION 5.1. WAIVER. Whenever a notice is required to be given by any
provision of law, by these By-Laws, or by the Certificate of Incorporation, a
waiver thereof in writing, whether before or after the time stated therein,

a committee of directors need be specified in any written waiver of notice
unless so required by the certificate of incorporation or the bylaws.

Corporation Law of the State 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.

to receive payment of any dividend or other distribution or allotment of any
rights or 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 payment, exercise or other

principal, premium or Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Issuers in making any such
payment. While any such default continues, the Trustee may require a Paying

form of a beneficial interest in an Unrestricted Global Note at any time. Upon
receipt of a request for such an exchange or transfer, the Trustee shall cancel
the applicable Unrestricted Definitive Note and increase or cause to be
increased the aggregate principal amount of one of the Unrestricted Global
Notes.

              If any such exchange or transfer from a Definitive Note to a
beneficial interest is effected pursuant to subparagraphs (ii)(B), (ii)(D) or
(iii) above at a time when an Unrestricted Global Note has not yet been issued,
the Issuers shall issue and, upon receipt of an Authentication Order in
accordance with Section 2.02 hereof, the Trustee shall authenticate one or more
Unrestricted Global Notes in an aggregate principal amount equal to the
principal amount of Definitive Notes so transferred.

       (e)    Transfer and Exchange of Definitive Notes for Definitive Notes.
Upon request by a Holder of Definitive Notes and such Holder's compliance with
the provisions of this Section 2.06(e), the Registrar shall register the
transfer or exchange of Definitive Notes. Prior to such registration of transfer
or exchange, the requesting Holder shall present or surrender to the Registrar
the Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or
by his or her attorney, duly authorized in writing. In addition, the requesting
Holder shall provide any additional certifications, documents and information,
as applicable, required pursuant to the following provisions of this Section
2.06(e).

          (i)  Restricted Definitive Notes to Restricted Definitive Notes. Any
     Restricted Definitive Note may be transferred to and registered in the name
     of Persons who take delivery thereof in the form of a Restricted Definitive
     Note if the Registrar receives the following:

               (A)  if the transfer will be made pursuant to Rule 144A under the
          Securities Act, then the transferor must deliver a certificate in the
          form of Exhibit B hereto, including the certifications in item (1)
          thereof;

               (B)  if the transfer will be made pursuant to Rule 903 or Rule
          904, then the transferor must deliver a certificate in the form of
          Exhibit B hereto, including the certifications in item (2) thereof;
          and

               (C)  if the transfer will be made pursuant to any other exemption
          from the registration requirements of the Securities Act, then the
          transferor must deliver a certificate in the form of Exhibit B hereto,
          including the certifications, certificates and Opinion of Counsel
          required by item (3) thereof, if applicable.

          (ii) Restricted Definitive Notes to Unrestricted Definitive Notes. Any
     Restricted Definitive Note may be exchanged by the Holder thereof for an
     Unrestricted Definitive Note or transferred to a Person or Persons who take
     delivery thereof in the form of an Unrestricted Definitive Note if:

               (A)  such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement
          and the Holder, in the case of an exchange, or the transferee, in the
          case of a transfer, certifies in the applicable Letter of Transmittal
          that it is not (1) a broker-dealer, (2) a Person participating in the
          distribution of the Exchange Notes or (3) a Person who is an affiliate
          (as defined in Rule 144) of the Issuers;

               (B)  any such transfer is effected pursuant to the Shelf
          Registration Statement in accordance with the Registration Rights
          Agreement;

               (C)  any such transfer is effected by a Participating
          Broker-Dealer pursuant to the Exchange Offer Registration Statement in
          accordance with the Registration Rights Agreement; or

               (D)  the Registrar receives the following:

                    (1)  if the Holder of such Restricted Definitive Notes
          proposes to exchange such Notes for an Unrestricted Definitive Note, a
          certificate from such Holder in the form of Exhibit C hereto,
          including the certifications in item (1)(d) thereof; or

                    (2)  if the Holder of such Restricted Definitive Notes
          proposes to transfer such Notes to a Person who shall take delivery
          thereof in the form of an Unrestricted Definitive Note, a certificate
          from such Holder in the form of Exhibit B hereto, including the
          certifications in item (4) thereof;

          and, in each such case set forth in this subparagraph (D), if the
          Registrar so requests, an Opinion of Counsel in form reasonably
          acceptable to the Issuers to the effect that such exchange or transfer
          is in compliance with the Securities Act and that the restrictions on
          transfer contained herein and in the Private Placement Legend are no
          longer required in order to maintain compliance with the Securities
          Act.

          (iii) Unrestricted Definitive Notes to Unrestricted Definitive Notes.
     A Holder of Unrestricted Definitive Notes may transfer such Notes to a
     Person who takes delivery thereof in the form of an Unrestricted Definitive
     Note. Upon receipt of a request to register such a transfer, the Registrar
     shall register the Unrestricted Definitive Notes pursuant to the
     instructions from the Holder thereof.

          (f) Exchange Offer. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Issuers shall issue and,
upon receipt of an Authentication Order in accordance with Section 2.02, the
Trustee shall authenticate (i) one or more Unrestricted Global Notes in an
aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Notes tendered for acceptance by Persons that
certify in the applicable Letters of Transmittal that (x) they are not
broker-dealers, (y) they are not participating in a distribution of the Exchange
Notes and (z) they are not affiliates (as defined in Rule 144) of the Issuers,

                                       28
<PAGE>   38


Definitive Notes accepted for exchange in the Exchange Offer. Concurrently with
the issuance of such Notes, the Trustee shall cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and
the Issuers shall execute and the Trustee shall authenticate and deliver to the
Persons designated by the Holders of Definitive Notes so accepted Definitive
Notes in the appropriate principal amount.

          (g)  Legends. The following legends shall appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

     (i)  Subordination Legend. Each Global Note and each Definitive Note shall

     GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON."

     (h)  Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note shall be increased accordingly
and an endorsement shall be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

               (i)  General Provisions Relating to Transfers and Exchanges.

          (i)  To permit registrations of transfers and exchanges, the Issuers
     shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon the Issuers' order or at the Registrar's request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Issuers may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

          (iii) The Registrar shall not be required to register the transfer of
     or exchange any Note selected for redemption in whole or in part, except
     the unredeemed portion of any Note being redeemed in part.

          (iv) All Global Notes and Definitive Notes issued upon any
     registration of transfer or exchange of Global Notes or Definitive Notes
     shall be the valid obligations of the Issuers, evidencing the same debt,
     and entitled to the same benefits under this Indenture, as the Global Notes
     or Definitive Notes surrendered upon such registration of transfer or
     exchange.

          (v)  The Issuers shall not be required (A) to issue, to register the
     transfer of or to exchange any Notes during a period beginning at the
     opening of business 15 days before the day of any selection of Notes for
     redemption under Section 3.02 hereof and ending at the close of business on
     the day of selection, (B) to register the transfer of or to exchange any
     Note so selected for redemption in whole or in part, except the unredeemed
     portion of any Note being redeemed in part 



                                       31
<PAGE>   41

     or (c) to register the transfer of or to exchange a Note between a record
     date and the next succeeding Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of
     any Note, the Trustee, any Agent and the Issuers may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of and interest on
     such Notes and for all other purposes, and none of the Trustee, any Agent
     or the Issuers shall be affected by notice to the contrary.

          (vii) The Trustee shall authenticate Global Notes and Definitive Notes
     in accordance with the provisions of Section 2.02 hereof.

          (viii) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.06 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

SECTION 2.07. REPLACEMENT NOTES.

               If any mutilated Note is surrendered to the Trustee or the
Issuers and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Issuers shall issue and the Trustee,
upon receipt of an Authentication Order, shall authenticate a replacement Note
if the Trustee's requirements are met. If required by the Trustee or the
Issuers, an indemnity bond must be supplied by the Holder that is sufficient in
the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee,
any Agent and any authenticating agent from any loss that any of them may suffer
if a Note is replaced. The Issuers may charge for their expenses in replacing a
Note.

               Every replacement Note is an additional obligation of the Issuers
and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

SECTION 2.08. OUTSTANDING NOTES.

               The Notes outstanding at any time are all the Notes authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Issuers or an Affiliate of the
Issuers holds the Note.

               If a Note is replaced pursuant to Section 2.07 hereof, it ceases
to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

               If the principal amount of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to
accrue.

               If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.



                                       32
<PAGE>   42


SECTION 2.09. TREASURY NOTES.

               In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Issuers, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuers, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that the Trustee knows are so owned
shall be so disregarded.

SECTION 2.10. TEMPORARY NOTES.

               Until certificates representing Notes are ready for delivery, the
Issuers may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Notes. Temporary Notes shall be substantially in
the form of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as shall be reasonably acceptable to the
Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee
shall authenticate definitive Notes in exchange for temporary Notes.

               Holders of temporary Notes shall be entitled to all of the
benefits of this Indenture.

SECTION 2.11. CANCELLATION.

               The Issuers at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes shall be delivered
to the Issuers. The Issuers may not issue new Notes to replace Notes that they
have paid or that have been delivered to the Trustee for cancellation.

SECTION 2.12. DEFAULTED INTEREST.

               If the Issuers default in a payment of interest on the Notes,
they shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and
the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special
record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the
Issuers (or, upon the written request of the Issuers, the Trustee in the name
and at the expense of the Issuers) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

                            REDEMPTION AND PREPAYMENT

SECTION 3.01. NOTICES TO TRUSTEE.

               If the Issuers elect to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, they shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED.

               If less than all of the Notes are to be redeemed or purchased in
an offer to purchase at any time, the Trustee shall select the Notes to be
redeemed or purchased among the Holders of the Notes 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 so listed, on a pro rata basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate; provided that no Notes of $1,000 or less shall be redeemed in part.
In the event of partial redemption by lot, the particular Notes to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption.

               The Trustee shall promptly notify the Issuers 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 and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
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.

               Subject to the provisions of Section 3.09 hereof, at least 30
days but not more than 60 days before a redemption date, the Company shall mail
or cause to be mailed, by first class mail, a notice of redemption to each
Holder whose Notes are to be redeemed at its registered address.

               The notice shall identify the Notes to be redeemed and shall
state:

          (a)  the redemption date;

          (b)  the redemption price;

          (c)  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
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original Note;

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



                                       34
<PAGE>   44

          (e)  that Notes called for redemption must be surrendered to the
Paying Agent to collect the redemption price;

          (f)  that, unless the Company defaults in making such redemption
payment, interest on Notes called for redemption ceases to accrue on and after
the redemption date;

          (g)  the paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

          (h)  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.

               At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Issuers shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

               Once notice of redemption is mailed in accordance with Section
3.03 hereof, Notes called for redemption become irrevocably due and payable on
the redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05. DEPOSIT OF REDEMPTION PRICE

               One Business Day prior to the redemption date, the Company shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Notes to be redeemed on that
date. The Trustee or the Paying Agent shall promptly return to the Company any
money deposited with the Trustee or the Paying Agent by the Company in excess of
the amounts necessary to pay the redemption price of, and accrued interest on,
all Notes to be redeemed.

               If the Issuers comply with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption shall not be so paid upon surrender for

               The Asset Sale Offer shall remain open for a period of 20
Business Days following its commencement and no longer, except to the extent

required to be purchased pursuant to Section 4.10 hereof (the "Offer Amount")
or, if less than the Offer Amount has been tendered, all Notes tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased shall be

               If the Purchase Date is on or after an interest record date and
on or before the related interest payment date, any accrued and unpaid interest
shall be paid to the Person in whose name a 




                                       36
<PAGE>   46

Note is registered at the close of business on such record date, and no
additional interest shall be payable to Holders who tender Notes pursuant to the
Asset Sale Offer.

               Upon the commencement of an Asset Sale Offer, the Company shall
send, by first class mail, a notice to the Trustee and each of the Holders, with
a copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

     (a)  that the Asset Sale Offer is being made pursuant to this Section 3.09
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

     (c)  that any Note not tendered or accepted for payment shall continue to
accrue interest;

     (d)  that, unless the Issuers default in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest after the Purchase Date;

     (e)  that Holders electing to have a Note purchased pursuant to an Asset
Sale Offer may only elect to have all of such Note purchased and may not elect
to have only a portion of such Note purchased;

     (f)  that Holders electing to have a Note purchased pursuant to any Asset
Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, a depositary, if appointed by
the Issuers, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

     (g)  that Holders shall be entitled to withdraw their election if the
Company, the depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

     (h)  that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Trustee shall select the Notes to be
purchased on a pro rata basis (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); and



                                       37
<PAGE>   47

     (i)  that Holders whose Notes were purchased only in part shall be issued
new Notes equal in principal amount to the unpurchased portion of the Notes
surrendered (or transferred by book-entry transfer).

               On or before the Purchase Date, the Issuers shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Issuers in accordance
with the terms of this Section 3.09. The Company, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in any case not later than five
days after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Notes tendered by such Holder and accepted by
the Issuers for purchase, and the Issuers shall promptly issue a new Note, and
the Trustee, upon written request from the Issuers shall authenticate and mail
or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuers to the Holder thereof. The Company
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date. Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

SECTION 4.01. PAYMENT OF NOTES.

               The Issuers shall pay or cause to be paid the principal of,
premium, if any, and interest on the Notes on the dates and in the manner
provided in the Notes. Principal, premium, if any, and interest shall be
considered paid on the date due if the Paying Agent, if other than the Company
or a Subsidiary thereof, holds as of 10:00 a.m. New York Time on the due date
money deposited by the Company in immediately available funds and designated for

affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Issuers in respect of the Notes and this Indenture may be
served. 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 Issuers shall fail to maintain any such required 



                                       38
<PAGE>   48

office or agency or the Company shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee.

               The Issuers may also from time to time designate one or more
other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Issuers of their obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

               The Issuers hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Issuers in accordance with Section
2.03.

SECTION 4.03. REPORTS.

     (a)  Whether or not required by the rules and regulations of the SEC, so
long as any Notes are outstanding, the Issuers shall furnish to the Trustee and
the Holders of Notes, within 15 days after the required filing date, (i) all

consolidated financial condition and results of operations of the Company,
UNICCO Finance and the Company's Restricted Subsidiaries separate from the
financial information and results of operations of the Unrestricted Subsidiaries
of the Company) and, with respect to the annual information only, a report
thereon by the Issuers' certified independent accountants and (ii) all current
reports that would be required to be filed with the SEC on Form 8-K if the
Issuers were required to file such reports. In addition, whether or not required
by the rules and regulations of the SEC, the Issuers shall file a copy of all
such information and reports with the SEC for public availability (unless the
SEC will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. The Issuers shall at
all times comply with TIA ss. 314(a).

     (b)  For so long as any Notes remain outstanding, the Issuers and the
Company's Restricted Subsidiaries shall furnish to the Holders and to securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

observed, performed and fulfilled their obligations under this Indenture and
further stating, as to each such Officer signing such certificate, that to the
best of his or her knowledge the Issuers and the Guarantors have kept, observed,
performed and fulfilled each and every covenant contained in this Indenture and

provisions and conditions of this Indenture (or, if a Default or Event of
Default shall have occurred, describing all such Defaults or Events of Default
of which he or she may have knowledge and what action the Issuers or such
Guarantor, as applicable, are taking or proposes to take with respect thereto)
and that to the best of his or her knowledge, no event has occurred and remains
in existence by reason of which payments on account of the principal of or
interest, if any, on the Notes is prohibited or if such event has occurred, a
description of the event and what action the Issuers or such Guarantor, as
applicable, are taking or proposes to take with respect thereto.

     (b)  So long as not contrary to the then current standards of the American
Institute of Certified Public Accountants, the year-end financial statements
delivered pursuant to Section 4.03(a) hereof shall be accompanied by a written
statement of the Company's independent public accountants (who shall be a firm
of established national reputation) that in making the examination necessary for
certification of such financial statements, nothing has come to their attention
that would lead them to believe that the Issuers have violated any provisions of
Article 4 or Article 5 hereof 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)  The Issuers shall, so long as any of the Notes are outstanding,
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Issuers are taking or propose to take with
respect thereto.

SECTION 4.05. TAXES.

               The Company shall pay, and shall cause each of its Subsidiaries

or where the failure to effect such payment is not adverse in any material
respect to the Holders of the Notes.

SECTION 4.06. STAY, EXTENSION AND USURY LAWS.



                                       40
<PAGE>   50


               The Issuers and each of the Guarantors covenant (to the extent
that they may lawfully do so) that they shall not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law wherever enacted, now or at any time hereafter
in force, that may affect the covenants or the performance of this Indenture;
and the Issuers and each of the Guarantors (to the extent that they may lawfully
do so) hereby expressly waives all benefit or advantage of any such law, and
covenants that they shall not, by resort to any such law, 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 has
been enacted.

SECTION 4.07. RESTRICTED PAYMENTS.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Company's Equity Interests
(including, without limitation, any payment in connection with any merger or
consolidation involving the Company) or to any direct or indirect holders of the
Company's Equity Interests in their capacity as such (other than dividends or
distributions (a) payable in Equity Interests (other than Disqualified Stock) of
the Company or (b) to the Company or any Wholly Owned Restricted Subsidiary of
the Company; (ii) purchase, redeem or otherwise acquire or retire for value

make any payment on or with respect to, or purchase, redeem, defease or
otherwise acquire or retire for value any Indebtedness of the Company or any

thereof, except a payment of interest or principal at Stated Maturity; or (iv)
make any Restricted Investment (all such payments and other actions set forth in
clauses (i) through (iv) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:

     (a)  no Default or Event of Default shall have occurred and be continuing
or would occur as a consequence thereof; and

     (b)  the Company would, at the time of such Restricted Payment and after
giving pro forma effect thereto as if such Restricted Payment has been made at
the beginning of the applicable four-quarter period, have been permitted to
incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge
Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof; and

     (c)  such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and its Restricted Subsidiaries
after the date of this Indenture (excluding Restricted Payments permitted by
clause (ii) through (v) of the next succeeding paragraph), is less than the sum
of (i) 50% of the Consolidated Net Income of the Company for the period (taken
as one accounting period) from the beginning of the first fiscal quarter
commencing after the date of this Indenture to the end of the Company's most
recently ended fiscal quarter for which internal financial statements are
available at the time of such Restricted Payment (or, if such Consolidated Net
Income for such period is a deficit, less 100% of such deficit), plus (ii) 100%
of the aggregate net cash proceeds received by the Company from the issue 



                                       41
<PAGE>   51

or sale since the date of this Indenture of Equity Interests of the Company
(other than Disqualified Stock) or Disqualified Stock or debt securities of the
Company that have been converted into such Equity Interests (other than Equity
Interests (or Disqualified Stock or convertible debt securities) sold to a
Subsidiary of the Company and other than Disqualified Stock or convertible debt
securities that have been converted into Disqualified Stock), plus (iii) 50% of
any dividends received by the Company or a Wholly Owned Restricted Subsidiary
after the date of this Indenture from an Unrestricted Subsidiary of the Company,
to the extent that such dividends that were not otherwise included in
Consolidated Net Income of the Company for such period.

               The foregoing provisions shall not prohibit (i) the payment of
any dividend within 60 days after the date of declaration thereof, if at the
date of declaration such payment would have complied with the provisions of this
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
or any Restricted Subsidiary in exchange for, or out of the net cash proceeds of
the substantially concurrent sale (other than to a Subsidiary of the Company)
of, other Equity Interests of the Company (other than any Disqualified Stock);
provided that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement, defeasance or other acquisition shall
be excluded from clause (c)(ii) of the preceding paragraph; (iii) the
defeasance, redemption, repurchase or other acquisition of subordinated
Indebtedness with the net cash proceeds from an incurrence of Permitted
Refinancing Indebtedness; (iv) for any period that the Company is treated as an
"S corporation" or a partnership for federal income tax purposes, distributions
to shareholders of the Company in an amount not to exceed the Tax Amount for
such period; (v) the redemption, retirement or defeasance of indebtedness with
the net proceeds of the Offering as contemplated under the caption "Use of
Proceeds" in the Offering Memorandum and (vi) the repurchase, redemption or
other acquisition or retirement for value of any Equity Interests of the Company
or any Restricted Subsidiary of the Company held by any member of the Company's
(or any of its Restricted Subsidiaries') management or Board of Directors
pursuant to any management equity subscription agreement, shareholders'
agreement, equity incentive plan, stock option agreement or other similar
agreement; provided that the aggregate price paid for all such repurchased,
redeemed, acquired or retired Equity Interests under this clause (vi) shall not
exceed the sum of (a) $500,000 in any twelve-month period plus (b) the aggregate
net proceeds received by the Company from the issuance after the date of this
Indenture of Equity Interests of the Company to members of management or the
Board of Directors of the Company or any of its Restricted Subsidiaries
(provided that such net proceeds shall be excluded from clause (c)(ii) of the
preceding paragraph), and, for purposes of this clause (vi), in each case, no
Default or Event of Default shall have occurred and be continuing immediately
after such transaction.

               The amount of all Restricted Payments (other than cash) shall be
the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any non-cash Restricted Payment shall be determined in
good faith by the Board of Directors whose resolution with respect thereto shall
be delivered to the Trustee. Not later than the date of making any Restricted
Payment, the Company shall deliver to the Trustee an Officers' Certificate
stating that such Restricted Payment is permitted and setting forth the basis
upon which the calculations required by this Section 4.07 were computed.



                                       42
<PAGE>   52


               The Board of Directors may designate any Restricted Subsidiary to
be an Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated shall be deemed to be Restricted Payments at the
time of such designation and shall reduce the amount available for Restricted
Payments under the first paragraph of this Section 4.07. All such outstanding
Investments shall be deemed to constitute Investments in an amount equal to the
greatest of (i) the net book value of such Investments at the time of such
designation, (ii) the fair market value of such Investments at the time of such
designation and (iii) the original fair market value of such Investments at the
time they were made. Such designation shall only be permitted if such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary.

               Any such designation by the Board of Directors shall be evidenced
to the Trustee by filing with the Trustee a certified copy of the board
resolution giving effect to such designation and an Officers' Certificate
certifying that such designation complied with the foregoing conditions. If, at
any time, any Unrestricted Subsidiary would fail to meet the definition of an
Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted
Subsidiary for purposes of this Indenture and any Indebtedness of such
Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of the
Company as of such date (and, if such Indebtedness is not permitted to be
incurred as of such date under Section 4.09 hereof, the Issuers shall be in
default of such Section). The Board of Directors may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such
designation shall be deemed to be an incurrence of Indebtedness by a Restricted
Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary and such designation shall only be permitted if (i) such Indebtedness
is permitted under Section 4.09 hereof, calculated on a pro forma basis as if
such designation had occurred at the beginning of the four-quarter reference
period, and (ii) no Default or Event of Default would be in existence following
such designation.

SECTION 4.08. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

               The Issuers shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (a)(i) pay dividends or make any other distributions to
the Company or any of its Restricted Subsidiaries (A) on its Capital Stock or
(B) with respect to any other interest or participation in, or measured by, its
profits or (ii) pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries, (b) make loans or advances to the Company or any of its
Restricted Subsidiaries or (c) transfer any of its properties or assets to the
Company or any of its Restricted Subsidiaries, except for such encumbrances or
restrictions existing under or by reasons of (i) Existing Indebtedness as in
effect on the date of this Indenture, (ii) the Credit Facility as in effect on
the date of this Indenture and any amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings
thereof, provided that such amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings are no more
restrictive with respect to such dividend and other payment restrictions than
those contained in the Credit Facility as in effect on the date of this
Indenture, (iii) this Indenture and the Notes, (iv) applicable law, (v) any
instrument governing Indebtedness or Capital Stock of a 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), which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person, so acquired,




                                       43
<PAGE>   53


provided that, in the case of Indebtedness, such Indebtedness was permitted by
the terms of this Indenture to be incurred, (vi) by reason of customary
non-assignment provisions in leases entered into in the ordinary course of
businesses, (vii) purchase money obligations for property acquired in the
ordinary course of business that impose restrictions of the nature described in
clause (c) above on the property so acquired, (viii) Permitted Refinancing
Indebtedness, provided that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are no more restrictive than
those contained in the agreements governing the Indebtedness being refinanced,
or (ix) any Purchase Money Note, or other Indebtedness or contractual
requirements incurred with respect to a Qualified Receivable Transaction
relating to a Receivables Subsidiary.

SECTION 4.09. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and that the Company shall not permit any of its Restricted Subsidiaries
to issue any shares of preferred stock (other than to the Company or to another
Restricted Subsidiary); provided, however, that the Company and its Restricted
Subsidiaries may incur Indebtedness (including Acquired Debt) and the Company's
Restricted Subsidiaries may issue preferred stock if the Fixed Charge Coverage
Ratio for the Company's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred or such preferred stock is issued
would have been at least 2.0 to 1, determined on a pro forma basis (including a
pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the preferred stock had been issued at the
beginning of such four-quarter period.

               The provisions of the first paragraph of this Section 4.09 shall
not apply to the incurrence of any of the following (collectively, "Permitted
Debt");

          (i)  the incurrence by the Company or its Restricted Subsidiaries of
     Indebtedness under the Credit Facility; in an aggregate amount not to
     exceed at any time outstanding the greater of (a) $45.0 million, less the
     aggregate amount of all Net Proceeds of Asset Sales applied to repay any
     such Indebtedness pursuant to clause (a) of the second paragraph of Section
     4.10 and (b) 60% of the Company's and its Restricted Subsidiaries' accounts
     receivable (net of reserves), as shown on the Company's most recent
     consolidated balance sheet;

          (ii) the incurrence by the Company of Indebtedness represented by the
     Notes and this Indenture;

          (iii) the incurrence by the Company and its Restricted Subsidiaries of
     the Existing Indebtedness;

          (iv) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     that was permitted to be incurred by the first paragraph, or by clauses
     (ii) through (ix) of the second paragraph of this Section 4.09;



                                       44
<PAGE>   54


          (v)  the incurrence of Indebtedness between or among the Company and
     any of its Wholly Owned Restricted Subsidiaries; provided, however, that
     (a) if the Company is the obligor on such Indebtedness, such Indebtedness
     is expressly subordinated to the prior payment in full of all Obligations
     with respect to the Notes and (b) any subsequent issuance or transfer of
     Equity Interests that results in any such Indebtedness being held by a
     Person other than the Company or a Wholly Owned Restricted Subsidiary, and
     any sale or other transfer of any such Indebtedness to a Person that is not
     either the Company or a Wholly Owned Restricted Subsidiary, shall be
     deemed, in each case, to constitute an incurrence of such Indebtedness by
     the Company or such Restricted Subsidiary, as the case may be;

          (vi) the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     fixing or hedging interest rate risk with respect to any floating rate
     Indebtedness that is permitted by the terms of this Indenture to be
     outstanding;

          (vii) the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate amount not to
     exceed $10.0 million at any time outstanding;

          (viii) the guarantee by the Company or any of its Restricted
     Subsidiaries of Indebtedness that was permitted to be incurred by another
     provision of this Section 4.09; and

          (ix) Indebtedness of a Receivables Subsidiary that is not recourse to
     the Company or any of its Restricted Subsidiaries (other than Standard
     Securitization Undertakings) incurred in connection with a Qualified
     Receivables Transaction.

               For purposes of determining compliance with this Section 4.09, in
the event that an item of Indebtedness meets the criteria of more than one of
the categories of Permitted Debt described in clauses (i) through (ix) above or
is entitled to be incurred pursuant to the first paragraph of this Section 4.09,
the Company shall, in its sole discretion, classify such item of Indebtedness in
any manner that complies with this Section 4.09 and such item of Indebtedness
will be treated as having been incurred pursuant to only one of such clauses or
pursuant to the first paragraph hereof. Accrual of interest, the accretion of
accreted value and the payment of interest in the form of additional
Indebtedness shall not be deemed to be an incurrence of Indebtedness for
purposes of this Section 4.09.

SECTION 4.10. ASSET SALES

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the fair market value (evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (ii) at least 80% of the consideration therefor
received by the Company or such Restricted Subsidiary is in the form of cash;
provided that the amount of (a) any liabilities (as shown on the Company's or
such Restricted Subsidiary's most recent balance sheet) of the Company or such
Restricted Subsidiary (other than contingent liabilities and liabilities that
are by their terms subordinated to the Notes or any Guarantee thereof) that are
assumed by the transferee of any such assets pursuant to a customary novation
agreement that releases the Company or such Restricted Subsidiary from further
liability and (b) any securities, notes or other obligations received by the
Company or such Restricted Subsidiary from such 



                                       45
<PAGE>   55

transferee that are immediately converted by the Company or such Restricted
Subsidiary into cash (to the extent of the cash received) shall be deemed to be
cash for purposes of this provision.

               Within 360 days after the receipt of any Net Proceeds from an
Asset Sale, the Company may apply such Net Proceeds, at its option, (a) to repay
Senior Debt (and to correspondingly reduce commitments with respect thereto in
the case of revolving borrowings) or (b) to the acquisition of a controlling
interest in another business, the making of a capital expenditure or the
acquisition of other long-term assets. Pending the final application of any such
Net Proceeds, the Company may temporarily reduce Senior Debt or otherwise invest
such Net Proceeds in any manner that is not prohibited by this Indenture. Any
Net Proceeds from Asset Sales that are not applied or invested as provided in
the first sentence of this paragraph shall be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $5.0 million,
the Company shall be required to make an offer to all Holders of Notes (an
"Asset Sale Offer") to purchase the maximum principal amount of Notes that may
be purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase, in accordance
with the procedures set forth in this Indenture. To the extent that the
aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Company may use any remaining Excess Proceeds
for general corporate purposes. If the aggregate principal amount of Notes
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes to be purchased on a pro rata basis. Upon
completion of an Asset Sale Offer, the amount of Excess Proceeds shall be reset
at zero.

SECTION 4.11. TRANSACTIONS WITH AFFILIATES.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless
(a) such Affiliate Transaction is on terms that are no less favorable to the
Company or such Restricted Subsidiary than those that would have been obtained
in a comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person and (b) the Company delivers to the Trustee (i) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $0.5 million, a resolution of the Board of
Directors set forth in an Officers' Certificate certifying that such Affiliate
Transaction complies with clause (a) above and that such Affiliate Transaction
has been approved by a majority of the disinterested members of the Board of
Directors, if any, and (ii) with respect to any Affiliate Transaction or series
of related Affiliate Transactions involving aggregate consideration in excess of
$4.0 million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an investment banking firm
of national standing.

               The foregoing provisions shall not prohibit: (i) any employment
agreement or other employment or compensation agreement entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business; (ii) transactions between or among the Company and/or its Restricted
Subsidiaries and/or UNICCO Finance; (iii) direct or indirect transactions
between the Company or any of its Restricted Subsidiaries, on the one hand, and
Ashmont Insurance Company, Limited or any of its subsidiaries, on the other
hand, on terms that are not materially less favorable to the Company or the
applicable Restricted Subsidiary than those that could have been obtained from
an unaffiliated third party; (iv) the transactions contemplated under the
caption "Use of Proceeds" 




                                       46
<PAGE>   56

contained in the Offering Memorandum; (v) notes payable to or receivable from,
and leases of real property from, Affiliates (and payments thereunder) as in
effect on the date of this Indenture, as the same may be amended, modified,
renewed or extended in a manner no less favorable to the Company and its
Restricted Subsidiaries; (vi) any Restricted Payment that is permitted by
Section 4.07 hereof; and (vii) sales of accounts receivable and other related
assets customarily transferred in an asset securitization transaction involving
accounts receivable to a Receivables Subsidiary in a Qualified Receivables
Transaction.

SECTION 4.12. LIENS.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist
any Lien securing Indebtedness or trade payables on any asset now owned or
hereafter acquired, or any income or profits therefrom or assign or convey any
right to receive income therefrom, except Permitted Liens.

SECTION 4.13. ACTIVITIES OF UNICCO FINANCE.

               UNICCO Finance shall not hold any material assets, become liable
for any material obligations or engage in any significant business activities;
provided, however, that UNICCO Finance may be a co-obligor or guarantor with
respect to, and may pledge its assets to secure, Indebtedness of which the
Company is an obligor.

SECTION 4.14. CORPORATE EXISTENCE.

               Subject to Article 5 hereof, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect (i) its
business trust existence, and the corporate, partnership or other existence of
each of its Subsidiaries, in accordance with the respective organizational
documents (as the same may be amended from time to time) of the Company or any
such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses
and franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise,
or the corporate, partnership or other existence of any of its Subsidiaries, if
the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and its
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders of the Notes.

SECTION 4.15. OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

     (a)  Upon the occurrence of a Change of Control, the Issuers shall make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes at an
Offer price in cash equal to 101% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon, to the date of
purchase (the "Change of Control Payment"). Within 30 days following a Change of
Control, the Issuers shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and stating:
(1) that the Change of Control Offer is being made pursuant to this Section 4.15
and that all Notes tendered will be accepted for payment; (2) the purchase price
and the purchase date, which shall be no later than 30 business 



                                       47

<PAGE>   57

days from the date such notice is mailed (the "Change of Control Payment Date");
(3) that any Note not tendered will continue to accrue interest; (4) that,
unless the Issuers default in the payment of the Change of Control Payment, all
Notes accepted for payment pursuant to the Change of Control Offer shall cease
to accrue interest after the Change of Control Payment Date; (5) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer will
be required to surrender the Notes, with the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at
the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; (6) that Holders will
be entitled to withdraw their election if the Paying Agent receives, not later
than the close of business on the second Business Day preceding the Change of
Control Payment Date, a telegram, telex, facsimile transmission or letter
setting forth the name of the Holder, the principal amount of Notes delivered
for purchase, and a statement that such Holder is withdrawing his election to
have the Notes purchased; and (7) that Holders whose Notes are being purchased
only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered, which unpurchased portion must be
equal to $1,000 in principal amount or an integral multiple thereof. The Issuers
shall comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of Notes in
connection with a Change of Control.

     (b)  On the Change of Control Payment Date, the Issuers shall, to the
extent lawful, (1) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Issuers. The Paying Agent shall promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes, if any; provided that each such new Note shall be in a principal
amount of $1,000 or an integral multiple thereof. Prior to complying with the
provisions of this Section 4.15, but in any event within 90 days following a
Change of Control, the Issuers shall either repay all outstanding Senior Debt or
obtain the requisite consents, if any, under all agreements governing
outstanding Senior Debt to permit the repurchase of Notes required by this
Section 4.15. The Issuers shall publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

     (c)  Notwithstanding anything to the contrary in this Section 4.15, the
Issuers shall not be required to make a Change of Control Offer following a
Change of 




                                       48
<PAGE>   58

Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof and purchases all Notes validly tendered
and not withdrawn under such Change of Control Offer.

SECTION 4.16. LIMITATION ON OTHER SENIOR SUBORDINATED DEBT.

               Notwithstanding the provisions of Section 4.09 hereof, neither
the Company nor any Restricted Subsidiary shall incur any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt of the Company or
such Restricted Subsidiary, as the case may be, and senior in any respect in
right of payment to the Notes or such Restricted Subsidiary's Guarantee thereof.

SECTION 4.17. PAYMENTS FOR CONSENT.

               Neither the Company nor UNICCO Finance nor any of the Company's
Restricted Subsidiaries shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes 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 or is paid to all Holders of the Notes that
consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

SECTION 4.18. ADDITIONAL NOTE GUARANTEES.

               If the Company or any of its Domestic Restricted Subsidiaries
shall acquire or create another Domestic Restricted Subsidiary after the date of
this Indenture, or any Unrestricted Subsidiary shall cease to be an Unrestricted
Subsidiary and shall become a Domestic Restricted Subsidiary, then such
Subsidiary shall execute a guarantee of the Notes and deliver an Opinion of
Counsel unless such Subsidiary shall have been designated a Receivables
Subsidiary in accordance with the terms of this Indenture.

SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

such Guarantor, as the case may be, is the surviving entity), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets in one or more related transactions, to another
corporation, Person or entity unless (i) the Company, UNICCO Finance or such
Guarantor, as the case may be, is the surviving entity, or the entity or the

Guarantor) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company, UNICCO Finance or such Guarantor, as the case may
be, under the Notes or such Guarantor's Note Guarantee thereof and this
Indenture pursuant

(iii) immediately after such transaction no Default or Event of Default exists;
and (iv) except in the case of a merger of the Company or a Guarantor with or
into the Company or another Guarantor, the Company, such Guarantor or the entity
or Person formed by or surviving any such consolidation or merger (if other than
the Company or such Guarantor), or to which such sale, assignment, transfer,

such transaction and after giving pro forma effect thereto (including pro forma

beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the first paragraph of Section 4.09 hereof.

SECTION 5.02. SUCCESSOR CORPORATION SUBSTITUTED.

the assets of the Company, UNICCO Finance or any Guarantor in accordance with
Section 5.01 hereof, the successor corporation formed by such consolidation or
into or with which the Company, UNICCO Finance or such Guarantor is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company," "UNICCO Finance" or
such "Guarantor" shall refer instead to the successor corporation and not to the
Company, UNICCO Finance or such Guarantor), and may exercise every right and
power of the Company, UNICCO Finance or such Guarantor under this Indenture with
the same effect as if such successor Person had been named as the Company,
UNICCO Finance or such Guarantor herein; provided, however, that the predecessor
Company, UNICCO Finance or Guarantor shall not be relieved from the obligation
to pay the principal of and interest on the Notes except in the case of a sale

SECTION 6.01. EVENTS OF DEFAULT.

               An "Event of Default" occurs if:

     (a)  the Issuers default in the payment when due of interest on, or
Liquidated Damages, if any, with respect to, the Notes and such default
continues for a period of 30 days (whether or not prohibited by Article 10

any Indebtedness for money borrowed by the Company, UNICCO Finance or any of the
Company's Restricted Subsidiaries (or the payment of which is guaranteed by the
Company, UNICCO Finance or any of the Company's Restricted Subsidiaries),
whether such Indebtedness or guarantee now exists, or is created after the date
of this Indenture, which default (i) is caused by a failure to pay principal of
or premium, if any, or interest on such Indebtedness prior to the expiration of
the grace period provided in such Indebtedness on the date of such default (a
"Payment Default") or (ii) results in the acceleration of such Indebtedness

     Company that, taken as a whole, would constitute a Significant Subsidiary
     in an involuntary case;

          (iii) orders the liquidation of the Company, UNICCO Finance, any
     Significant Subsidiary or any group of Restricted Subsidiaries of the
     Company, that, taken as a whole, would constitute a Significant Subsidiary;

     and the order or decree remains unstayed and in effect for 60 consecutive
     days;

          (i)  the Refinancing (as defined in the Offering Memorandum) shall not
have been consummated by 11:59 p.m., New York City time, on the date of this
Indenture; or

          (j)  except as permitted by this Indenture, any Note Guarantee is held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Restricted Subsidiary, or any
Person acting on behalf of any Restricted Subsidiary, shall deny or disaffirm
its obligations under its Note Guarantee.

SECTION 6.02. ACCELERATION.

               If any Event of Default (other than an Event of Default specified
in clause (g) or (h) of Section 6.01 hereof occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately.
Upon any such declaration, the Notes shall become due and payable immediately.
Notwithstanding the foregoing, if an Event of Default specified in clause (g) or
(h) of Section 6.01 hereof occurs with respect to the Company, UNICCO Finance,
any Significant Subsidiary or any group of Restricted Subsidiaries of the
Company that, taken as a whole, would constitute a Significant Subsidiary, all
outstanding Notes shall be due and payable immediately without further action or
notice. Holders of the Notes may not enforce this Indenture or the Notes except
as provided herein. The Holders of a majority in aggregate principal amount of
the then outstanding Notes by written notice to the Trustee may on behalf of all
of the Holders rescind an acceleration and its consequences if the rescission
would not conflict with any judgment or decree and if all existing Events of
Default (except nonpayment of principal, interest or premium that has become due
solely because of the acceleration) have been cured or waived.

               If an Event of Default occurs on or after October 15, 2002 by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Issuers with the intention of avoiding payment of the premium that the
Issuers would have had to pay if the Issuers then had elected to redeem the
Notes pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Notes to the
contrary notwithstanding. If an Event of Default occurs prior to October 15,
2002 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Issuers with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, upon acceleration of the
Notes, an additional premium shall also become and be immediately due and
payable so that the Issuers shall be obligated to pay an amount (expressed as

SECTION 6.03. OTHER REMEDIES.

               If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and 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 of a Note 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. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04. WAIVER OF PAST DEFAULTS.

               Holders of not less than a majority in aggregate 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 hereunder, except a continuing Default or Event of Default in
the payment of the principal of, premium and Liquidated Damages, if any, or
interest on, the Notes (including in connection with an offer to purchase)
(provided, however, that the Holders of a majority in aggregate principal amount
of the then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.05. CONTROL BY MAJORITY.

               Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

SECTION 6.06. LIMITATION ON SUITS.

               A Holder of a Note may pursue a remedy with respect to this
Indenture, the Notes, or the Note Guarantees only if:

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

               (b)  the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy;

               (c)  such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;



                                       53
<PAGE>   63

               (d)  the Trustee does not comply with the request within 60 days
after receipt of the request and the offer and, if requested, the provision of
indemnity; and

               (e)  during such 60-day period the Holders of a majority in
principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with the request.

               A Holder of a Note may not use this Indenture to prejudice the
rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note.

SECTION 6.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

               Notwithstanding any other provision of this Indenture, the right
of any Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), 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 specified in Section 6.01(a) or (b) occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Issuers for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest 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 and counsel.

SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

               The Trustee is authorized to 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,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Issuers
(or any other obligor upon the Notes), their creditors or their property and
shall be entitled and empowered to collect, receive and distribute any money or
other property payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and in the event that 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, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. 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, 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 pursuant to this Article 6, it
shall pay out the money in the following order:

               First: to the Trustee, its agents and attorneys for amounts due
under Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and

               Third: to the Issuers or to such party as a court of competent
jurisdiction shall direct.

               The Trustee may fix a record date and payment date for any
payment to Holders of Notes 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 a 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 and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.


                                   ARTICLE 7.
                                    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, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

          (i)  the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

          (ii) 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 



                                       55
<PAGE>   65

     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)  The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

          (i)  this paragraph does not limit the effect of paragraph (b) of this
     Section 7.01;

          (ii) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it is proved that the Trustee
     was negligent in ascertaining the pertinent facts; and

          (iii) 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 6.05 hereof.

          (d)  Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), (c), (e) and (f) of this Section 7.01 and Section 7.02 hereof.

          (e)  No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

          (f)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Issuers.

except to the extent required by law.

SECTION 7.02. RIGHTS OF TRUSTEE.

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 require
an Officers' Certificate or an Opinion of Counsel or both. 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. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

          (c)  The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

demand, request, direction or notice from the Issuers shall be sufficient if
signed by an Officer of each of the Issuers.

          (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 or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that might be incurred by it in compliance with such request or direction.

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 Issuers, the
Guarantors, or any Affiliate of the Issuers or the Guarantors with the same
rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest 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 and duties. The Trustee is also subject
to Sections 7.10 and 7.11 hereof.

SECTION 7.04. TRUSTEE'S DISCLAIMER.

               The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, the Notes or
the Note Guarantees, it shall not be accountable for the Company's use of the
proceeds from the Notes or any money paid to the Issuers or upon the Issuers'
direction under any provision of this Indenture, it shall not be responsible for
the use or application of any money received by any Paying Agent other than the
Trustee, and it shall not be responsible for any statement or recital herein or
any statement in the Notes or any other document in connection with the sale of
the Notes or pursuant to this Indenture other than its certificate of
authentication.

SECTION 7.05. NOTICE OF DEFAULTS.

               If a Default or Event of Default occurs and is continuing and if
it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice
of the Default or Event of Default within 90 days after it occurs. Except in the
case of a Default or Event of Default in payment of principal of, premium, if
any, or interest on any Note, the Trustee may withhold the notice if and so long
as a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of the Holders of the Notes.

SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

               Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(a) has occurred within the twelve months
preceding the reporting date, no 



                                       57
<PAGE>   67

report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 313(c).

               A copy of each report at the time of its mailing to the Holders
of Notes shall be mailed to the Issuers and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA ss. 313(d). The
Issuers shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

SECTION 7.07. COMPENSATION AND INDEMNITY.

               The Issuers and the Guarantors shall pay to the Trustee from time
to time reasonable compensation for its acceptance of this Indenture and
services hereunder. The Trustee's compensation shall not be limited by any law
on compensation of a trustee of an express trust. The Issuers and the Guarantors
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

               The Issuers and the Guarantors shall indemnify the Trustee
against any and all losses, liabilities or expenses incurred by it arising out
of or in connection with the acceptance or administration of its duties under
this Indenture, including the costs and expenses of enforcing this Indenture
against the Issuers and the Guarantors (including this Section 7.07) and
defending itself against any claim (whether asserted by either Issuer, any
Guarantor or any Holder or any other person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, except to the
extent any such loss, liability or expense may be attributable to its negligence
or bad faith. The Trustee shall notify the Issuers and the Guarantors promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Issuers and the Guarantors shall not relieve the Issuers and the
Guarantors of their obligations hereunder. The Issuers and the Guarantors shall
defend the claim and the Trustee shall cooperate in the defense. The Trustee may
have separate counsel and the Issuers and the Guarantors shall pay the
reasonable fees and expenses of such counsel. The Issuers and the Guarantors
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

               The obligations of the Issuers and the Guarantors under this
Section 7.07 shall survive the satisfaction and discharge of this Indenture.

               To secure the Issuers' and the Guarantors' payment obligations in
this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money
or property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture.

               When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses
and the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law.

               The Trustee shall comply with the provisions of TIA ss. 313(b)(2)
to the extent applicable.

SECTION 7.08. REPLACEMENT OF TRUSTEE.

               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.

               The Trustee may resign in writing at any time and be discharged
from the trust hereby created by so notifying the Issuers. The Holders of Notes
of a majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may
remove the Trustee if:

          (a)  the Trustee fails to comply with Section 7.10 hereof;

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

          (c)  a Custodian or public officer takes charge of the Trustee or its
property; or

          (d)  the Trustee becomes incapable of acting.

               If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Issuers 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 then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Issuers.

               If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers,
or the Holders of Notes 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, after written request by any Holder of a Note who
has been a Holder of a Note for at least six months, fails to comply with
Section 7.10, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

               A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon, 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. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Issuers' and the Guarantors' obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

<PAGE>   69


               If the Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Trustee.

SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

               There shall at all times be a Trustee hereunder that is a
corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise
corporate trustee power, that is subject to supervision or examination by
federal or state authorities and that has a combined capital and surplus of at
least $100 million as set forth in its most recent published annual report of
condition.

               This Indenture shall always have a Trustee who satisfies the
requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA
ss. 310(b).

SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS.

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

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

               The Issuers may, at the option of their Board of Directors
evidenced by a resolution set forth in an Officers' Certificate, at any time,
elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding
Notes upon compliance with the conditions set forth below in this Article Eight.

SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

               Upon the Issuers' exercise under Section 8.01 hereof of the
option applicable to this Section 8.02, the Issuers and each Guarantor shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all
outstanding Notes and Note Guarantees on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that the Issuers and each Guarantor shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding Notes
and Guarantees, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all of their other
obligations under such Notes and Note Guarantees and this Indenture (and the
Trustee, on demand of and at the expense of the Issuers, shall execute proper
instruments acknowledging the same), except for the following provisions which
shall survive until otherwise terminated or discharged hereunder: (a) the rights
of Holders of outstanding Notes to receive payments in respect of the principal
of, and premium, interest and Liquidated Damages, if any, on the Notes when such
payments are due solely from the trust fund described in Section 8.04 hereof,
and as more fully set forth in such Section, (b) the Issuers' obligations with
respect to the Notes under Article 2 and Section 4.02 hereof, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and the Issuers'
obligations in connection therewith and (d) this Article Eight. Subject to



                                       60

<PAGE>   70

compliance with this Article Eight, the Issuers may exercise their option under
this Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof.

SECTION 8.03. COVENANT DEFEASANCE.

               Upon the Issuers' exercise under Section 8.01 hereof of the
option applicable to this Section 8.03, the Issuers shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from their obligations under the covenants contained in Sections 4.07, 4.08,
4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.17 and 4.18 hereof with respect to the
outstanding Notes and Note Guarantees on and after the date the conditions set
forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and
the Notes and Note Guarantees shall thereafter be deemed not "outstanding" for
the purposes of any direction, waiver, consent or declaration or act of Holders
(and the consequences of any thereof) in connection with such covenants, but
shall continue to be deemed "outstanding" for all other purposes hereunder (it
being understood that such Notes and Note Guarantees shall not be deemed
outstanding for accounting purposes). For this purpose, "Covenant Defeasance"
means that, with respect to the outstanding Notes and Note Guarantees, the
Issuers and Guarantors may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01 hereof,
but, except as specified above, the remainder of this Indenture, such Notes and
Note Guarantees shall be unaffected thereby. In addition, upon the Issuers'
exercise under Section 8.01 hereof of the option applicable to this Section 8.03
hereof, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, Sections 6.01(d) through 6.01(f) hereof shall not constitute Events of
Default.

SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

               The following shall be the conditions to the application of
either Section 8.02 or 8.03 hereof to the outstanding Notes and Note Guarantees:

In order to exercise either Legal Defeasance or Covenant Defeasance:

          (a)  the Issuers must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders of the Notes, cash in U. S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of and premium, interest and Liquidated
Damages, if any, on the outstanding Notes on the stated maturity or on the
applicable redemption date, as the case may be, and the Issues must specify
whether the Notes are being defeased to maturity or to a particular redemption
date;

          (b)  in the case of an election under Section 8.02 hereof, the Issuers
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (i) the Issuers have
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 Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal 


<PAGE>   71

Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred;

          (c)  in the case of an election under Section 8.03 hereof, the Issuers
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

          (d)  no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or insofar
as Sections 6.01(g) or 6.01(h) hereof is concerned, at any time in the period
ending on the 91st day after the date of deposit;

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

          (f)  the Issuers shall have delivered to the Trustee an Opinion of
Counsel (which may be subject to customary exceptions) to the effect that after
the 91st day following the deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors' rights generally;

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

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

SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
OTHER MISCELLANEOUS PROVISIONS.

               Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Issuers acting as
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

               The Issuers shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to 



                                       62
<PAGE>   72

Section 8.04 hereof or the principal and interest received in respect thereof
other than any such tax, fee or other charge which by law is for the account of
the Holders of the outstanding Notes.

               Anything in this Article Eight to the contrary notwithstanding,
the Trustee shall deliver or pay to the Issuers from time to time upon the
request of the Issuers any money or non-callable Government Securities held by
it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

SECTION 8.06. REPAYMENT TO ISSUERS.

               Any money deposited with the Trustee or any Paying Agent, or then
held by the Issuers, in trust for the payment of the principal of, premium, if
any, or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Issuers on their request or (if then held by the Issuers) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as a
secured creditor, look only to the Issuers for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Issuers as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Issuers cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Issuers.

SECTION 8.07. REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or non-callable Government Securities in accordance with Section
8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Issuers' and the Guarantors' obligations
under this Indenture, the Notes and the Note Guarantees shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
hereof until such time as the Trustee or Paying Agent is permitted to apply all
such money in accordance with Section 8.02 or 8.03 hereof, as the case may be;
provided, however, that, if the Issuers make any payment of principal of,
premium, if any, or interest on any Note following the reinstatement of its
obligations, the Issuers shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money held by the Trustee or Paying
Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES.

               Notwithstanding Section 9.02 of this Indenture, the Issuers, the
Guarantors and the Trustee may amend or supplement this Indenture, the Note
Guarantees or the Notes without the consent of any Holder of a Note:



                                       63
<PAGE>   73


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

          (b)  to provide for uncertificated Notes in addition to or in place of
certificated Notes;

          (c)  to provide for the assumption of the Company's, UNICCO Finance's
or any Restricted Subsidiary's obligations to the Holders of the Notes in the
case of a merger or consolidation pursuant to Article 5 hereof;

          (d)  to make any change that would provide any additional rights or
benefits to the Holders of Notes or that does not adversely affect the legal
rights hereunder of any such Holder or;

          (e)  to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA.

               Upon the request of the Issuers accompanied by a resolution of
their Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company,
UNICCO Finance and the Guarantors in the execution of any amended or
supplemental Indenture authorized or permitted by the terms of this Indenture
and to make any further appropriate agreements and stipulations that may be
therein contained, but the Trustee shall not be obligated to enter into such
amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES.

               Except as provided below in this Section 9.02, the Company,
UNICCO Finance, the Guarantors and the Trustee may amend or supplement this
Indenture (including Sections 3.09, 4.10 and 4.15 hereof), the Note Guarantees
and the Notes with the consent of the Holders of at least a majority in
principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing
Default or Event of Default or compliance with any provision of this Indenture,
the Note Guarantees or the Notes may be waived with the consent of the Holders
of a majority in principal amount of the then outstanding Notes (including
consents obtained in connection with a tender offer or exchange offer for
Notes).

               Upon the request of the Issuers accompanied by a resolution of
the Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid,
and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Company, UNICCO Finance and the
Guarantors in the execution of such amended or supplemental Indenture unless
such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.





                                       64
<PAGE>   74

               It shall not be necessary for the consent of the Holders of Notes
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

               After an amendment, supplement or waiver under this Section
becomes effective, the Issuers shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Issuers to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Notes then
outstanding may waive compliance in a particular instance by the Issuers or the
Guarantors with any provision of this Indenture, the Notes or the Note
Guarantees. However, without the consent of each Holder affected, an amendment
or waiver under this Section 9.02 may not (with respect to any Notes or Note
Guarantees held by a non-consenting Holder):

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

          (b)  reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to the redemption of the Notes except as
provided above with respect to Sections 3.09, 4.10 and 4.15 hereof;

          (c)  reduce the rate of or change the time for payment of interest,
including default interest, on any Note;

          (d)  waive a Default or Event of Default in the payment of principal
of or premium, interest or Liquidated Damages, if any, on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in
aggregate principal amount of the Notes and a waiver of the payment default that
resulted from such acceleration);

          (e)  make any Note payable in money other than that stated in the
Notes;

          (f)  make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of or premium, interest or Liquidated Damages, if any, on the
Notes;

          (g)  waive a redemption payment with respect to any Note (other than a
payment required by Section 3.09, 4.10, or 4.15 hereof);

          (h)  release any Restricted Subsidiary from any of its obligations
under its Note Guarantee, except in accordance with the terms of this Indenture;
or

          (i)  make any change in the foregoing amendment and waiver provisions.

SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment or supplement to this Indenture, the Notes or
the Note Guarantees shall be set forth in a amended or supplemental Indenture
that complies with the TIA as then in effect.

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.




                                       65
<PAGE>   75

               Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note 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. However, any such Holder of a Note or subsequent Holder
of a Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES.

               The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Issuers in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

               Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

               The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Issuers may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, in addition to the documents required
by Section 11.04 hereof, an Officers' Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                   ARTICLE 10.
                                  SUBORDINATION

SECTION 10.01. AGREEMENT TO SUBORDINATE.

               The Issuers and the Guarantors agree, and each Holder by
accepting a Note agrees, that the Indebtedness evidenced by the Notes and the
Guarantees is subordinated in right of payment, to the extent and in the manner
provided in this Article 10 and Section 11.02, to the prior payment in full of
all Senior Debt of the Issuers and the Guarantors, (in each case, whether
outstanding on the date hereof or hereafter created, incurred, assumed or
guaranteed), as applicable, and that the subordination is for the benefit of the
holders of Senior Debt.

SECTION 10.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

               Upon any distribution to creditors of either Issuer in a
liquidation or dissolution of such Issuer or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to such Issuer or its
property, in an assignment for the benefit of creditors or any marshaling of
either Issuer's assets and liabilities:




                                       66
<PAGE>   76

          (a)  holders of Senior Debt of such Issuer shall be entitled to
receive payment in full in cash or Cash Equivalents of all Obligations due in
respect of such Senior Debt (including interest after the commencement of any
such proceeding at the rate specified in the documents governing the applicable
Senior Debt) before the Holders of Notes shall be entitled to receive any
payment with respect to the Notes (except that Holders may receive (i) Permitted
Junior Securities and (ii) payments and other distributions made from any
defeasance trust created pursuant to Section 8.01 hereof); and

          (b)  until all Obligations with respect to Senior Debt (as provided in
subsection (1) above) are paid in full in cash or Cash Equivalents, any
distribution to which Holders would be entitled but for this Article 10 shall be
made to holders of Senior Debt (except that Holders of Notes may receive (i)
Permitted Junior Securities and (ii) payments and other distributions made from
any defeasance trust created pursuant to Section 8.01 hereof), as their
interests may appear.

SECTION 10.03. DEFAULT ON DESIGNATED SENIOR DEBT.

               The Issuers may not make any payment upon or in respect of the
Notes and (other than (i) Permitted Junior Securities and (ii) payments and
other distributions made from any defeasance trust created pursuant to Section
8.01 hereof) if:

          (a)  a default in the payment of the principal of or premium or
interest on any Designated Senior Debt occurs and is continuing beyond any
applicable grace period; or

          (b)  any other default occurs and is continuing with respect to any
Designated Senior Debt that permits holders of the Designated Senior Debt as to
which such default relates to accelerate its maturity and the Trustee receives a
notice of default (a "Payment Blockage Notice") from a Representative of
Designated Senior Debt. If the Trustee receives any such Payment Blockage
Notice, no subsequent Payment Blockage Notice shall be effective for purposes of
this Section unless and until at least 360 days shall have elapsed since the
effectiveness of the immediately prior Payment Blockage Notice. No nonpayment
default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent
Payment Blockage Notice.

               The Issuers may and shall resume payments on the Notes:

               (1)  in the case of a payment default, upon the date which such
default is cured or waived pursuant to the terms of such Designated Senior Debt,
and

               (2)  in the case of a nonpayment default, the earlier of the date
on which such nonpayment default is cured or waived pursuant to the terms of
such Designated Senior Debt or 179 days after the date on which the applicable
Payment Blockage Notice is received, unless the maturity of such Designated
Senior Debt has been accelerated,

if this Article 10 otherwise permits the payment.



                                       67
<PAGE>   77

SECTION 10.04. ACCELERATION OF SECURITIES.

               If payment of the Securities is accelerated because of an Event
of Default, the Issuers shall promptly notify holders of Senior Debt of the
acceleration.

SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER.

               In the event that the Trustee or any Holder receives any payment
of any Obligations with respect to the Notes at a time when the Trustee or such
Holder, as applicable, has actual knowledge that such payment is prohibited by
Section 10.03 hereof, such payment shall be held by the Trustee or such Holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to, the holders of Senior Debt of the Issuers as their
interests may appear or their Representative under this Indenture or other
agreement (if any) pursuant to which such Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of all
Obligations with respect to such Senior Debt remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders of
such Senior Debt.

               With respect to the holders of Senior Debt of the Issuers, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article 10, and no implied covenants or
obligations with respect to the holders of such Senior Debt shall be read into
this Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of such Senior Debt, and shall not be liable to
any such holders if the Trustee shall pay over or distribute to or on behalf of
Holders or the Issuers or any other Person money or assets to which any holders
of such Senior Debt shall be entitled by virtue of this Article 10, except if
such payment is made when the Trustee has actual knowledge of any facts that
would cause such payment to violate this Article 10 (which shall include any
notice by BankBoston, N.A. that a default described in Section 10.03 (a) or (b)
hereof has occurred under the Credit Facility) or as a result of the willful
misconduct or gross negligence of the Trustee.

SECTION 10.06. NOTICE BY ISSUERS.

               The Issuers shall promptly notify the Trustee and the Paying
 Agent of any facts known to them that would cause a payment of any Obligations
with respect to the Notes to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt of the
Issuers as provided in this Article 10.

SECTION 10.07. SUBROGATION.

               After all Senior Debt of the Issuers is paid in full and until
the Notes are paid in full in cash or Cash Equivalents, Holders of Notes shall
be subrogated (equally and ratably with all other Indebtedness pari passu with
the Notes) to the rights of holders of such Senior Debt to receive distributions
applicable to such Senior Debt to the extent that distributions otherwise
payable to the Holders of Notes have been applied to the payment of such Senior
Debt. A distribution made under this Article 10 to holders of Senior Debt of the
Issuers that otherwise would have been made to Holders of Notes is not, as
between the Issuers and Holders, a payment by the Issuers on the Notes.




                                       68
<PAGE>   78

SECTION 10.08. RELATIVE RIGHTS.

               This Article 10 defines the relative rights of Holders of Notes
and holders of Senior Debt of the Issuers. Nothing in this Indenture shall:

               (1)  impair, as between the Issuers and Holders of Notes, the
obligation of the Issuers, which is absolute and unconditional, to pay principal
of and interest on the Notes in accordance with their terms;

               (2)  affect the relative rights of Holders of Notes and creditors
of the Issuers other than their rights in relation to holders of Senior Debt of
the Issuers; or

               (3)  prevent the Trustee or any Holder of Notes from exercising
its available remedies upon a Default or Event of Default, subject to the rights
of holders and owners of Senior Debt of the Issuers to receive distributions and
payments otherwise payable to Holders of Notes.

               If the Issuers fail because of this Article 10 to pay principal
of or interest on a Note on the due date, the failure is still a Default or
Event of Default.

SECTION 10.09. SUBORDINATION MAY NOT BE IMPAIRED BY ISSUERS.

               No right of any holder of Senior Debt of the Issuers to enforce
the subordination of the Indebtedness evidenced by the Notes shall be impaired
by any act or failure to act by the Issuers or any Holder or by the failure of
the Issuers or any Holder to comply with this Indenture.

SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

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

               Upon any payment or distribution of assets of either Issuer
referred to in this Article 10, the Trustee and the Holders of Notes shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Notes for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior Debt of
the Issuers and other Indebtedness of the Issuers, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article 10.

SECTION 10.11. RIGHTS OF TRUSTEE AND PAYING AGENT.

               Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless (i) the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of, or (ii) the Trustee has actual knowledge (as
described in Section 10.05 hereof) of facts that would cause the payment of any
Obligations with respect to the Notes to violate this Article 10. Only the
Issuers 




                                       69
<PAGE>   79

or a Representative may give the notice. Nothing in this Article 10 shall impair
the claims of, or payments to, the Trustee under or pursuant to Section 7.07
hereof.

               The Trustee in its individual or any other capacity may hold
Senior Debt of the Issuers with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights.

SECTION 10.12. AUTHORIZATION TO EFFECT SUBORDINATION.

               Each Holder of Notes, by the Holder's acceptance thereof,
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination as provided
in this Article 10, and appoints the Trustee to act as such Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding
referred to in Section 6.09 hereof at least 30 days before the expiration of the
time to file such claim, a Representative of Designated Senior Debt is hereby
authorized to file an appropriate claim for and on behalf of the Holders of the

SECTION 10.13. AMENDMENTS.

               The provisions of this Article 10 shall not be amended or
modified without the written consent of the holders of all Senior Debt of the
Issuers. Notwithstanding the foregoing, any amendment to the provisions of this
Article 10 shall require the consent of the Holders of at least 75% in aggregate
principal amount of the Notes then outstanding if such amendment would adversely
affect the rights of Holders of Notes.

                                   ARTICLE 11.
                                 NOTE GUARANTEES

SECTION 11.01. GUARANTEE.

               Subject to this Article 11, each of the Guarantors hereby,
jointly and severally, from and after the time such Guarantor first becomes a
Domestic Restricted Subsidiary of the Company, unconditionally guarantees to
each Holder of a Note authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Notes or the Obligations of the Issuers
hereunder or thereunder, that: (a) the principal of and premium, interest and
Liquidated Damages, if any, on the Notes will be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on
the overdue principal of premium, interest (to the extent permitted by law) and
Liquidated Damages, if any, on the Notes, if any, if lawful, and all other
Obligations of the Issuers to the Holders or the Trustee hereunder or thereunder
will be promptly paid in full or performed, all in accordance with the terms
hereof and thereof; and (b) in case of any extension of time of payment or
renewal of any Notes or any of such other Obligations, the same will be promptly
paid in full when due or performed in accordance with the terms of the extension
or renewal, whether at stated maturity, by acceleration or otherwise. Failing
payment when due of any amount so guaranteed or any performance so guaranteed
for whatever reason, the Guarantors shall be jointly and severally obligated to
pay the same immediately. Each Guarantor agrees that this is a guarantee of
payment and not a guarantee of collection.

               The Guarantors hereby agree that their 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 




                                       70
<PAGE>   80

provisions hereof or thereof, the recovery of any judgment against either of the
Issuers, 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 Guarantor hereby waives diligence, presentment, demand of payment, filing
of claims with a court in the event of insolvency or bankruptcy of the either of
the Issuers, any right to require a proceeding first against the Issuers,
protest, notice and all demands whatsoever and covenant that this Note Guarantee
shall not be discharged except by complete performance of the Obligations
contained in the Notes and this Indenture.

               If any Holder or the Trustee is required by any court or
otherwise to return to the Issuers, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Issuers or
the Guarantors, any amount paid by either to the Trustee or such Holder, this
Note Guarantee, to the extent theretofore discharged, shall be reinstated in
full force and effect.

               Each Guarantor agrees that it shall not be entitled to any right
of subrogation in relation to the Holders in respect of any Obligations
guaranteed hereby until payment in full of all Obligations guaranteed hereby.
Each Guarantor further agrees that, as between the Guarantors, on the 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 6 hereof
for the purposes of this Note 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 declaration of acceleration of
such Obligations as provided in Article 6 hereof, such Obligations (whether or
not due and payable) shall forthwith become due and payable by the Guarantors
for the purpose of this Note Guarantee. The Guarantors shall have the right to
seek contribution from any non-paying Guarantor so long as the exercise of such
right does not impair the rights of the Holders under the Note Guarantee.

SECTION 11.02. SUBORDINATION OF NOTE GUARANTEE.

               The Obligations of each Guarantor under its Note Guarantee
pursuant to this Article 11 shall be junior and subordinated to the Senior Debt
of such Guarantor on the same basis as the Notes are junior and subordinated to
Senior Debt of the Issuers. For the purposes of the foregoing sentence, the
Trustee and the Holders shall have the right to receive and/or retain payments
by any of the Guarantors only at such times as they may receive and/or retain
payments in respect of the Notes pursuant to this Indenture, including Article
10 hereof.

SECTION 11.03. LIMITATION ON GUARANTOR LIABILITY.

               Each Guarantor, and by its acceptance of Notes, each Holder,
hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance
for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Note Guarantee. To effectuate the foregoing intention,
the Trustee, the Holders and the Guarantors hereby irrevocably agree that the
obligations of such Guarantor under its Note Guarantee and this Article 11 shall
be limited to the maximum amount as will, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Guarantor that are
relevant under such laws, and after giving effect to any collections from,
rights to receive contribution from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under this
Article 11, result in the obligations of such Guarantor under its Note Guarantee
not constituting a fraudulent transfer or conveyance.

SECTION 11.04. EXECUTION AND DELIVERY OF NOTE GUARANTEE.

               To evidence its Note Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Note Guarantee substantially in
the form included in Exhibit E shall be endorsed by an Officer of such Guarantor
on each Note authenticated and delivered by the Trustee and that this Indenture
shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

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

               If an Officer whose signature is on this Indenture or on the Note
Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Note Guarantee is endorsed, the Note Guarantee shall be valid
nevertheless.

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

               In the event that the Company or any of its Domestic Restricted
Subsidiaries creates or acquires another Domestic Restricted Subsidiary
subsequent to the date of this Indenture or any Unrestricted Subsidiary shall
cease to be an Unrestricted Subsidiary and shall become a Domestic Restricted
Subsidiary, if required by Section 4.18 hereof, the Issuers shall cause such
Subsidiaries to execute supplemental indentures to this Indenture and Note
Guarantees in accordance with Section 4.18 hereof and this Article 11, to the
extent applicable.

SECTION 11.05. CONSOLIDATION, ETC. BY GUARANTORS.

               In case of any consolidation, merger, sale or conveyance by any
Guarantor in accordance with Section 5.01 hereof and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed
upon the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Guarantor, such successor
Person shall succeed to and be substituted for the Guarantor with the same
effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Note Guarantees to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Issuers and delivered to the Trustee. All the Note
Guarantees so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all of such Note
Guarantees had been issued at the date of the execution hereof.

SECTION 11.06. RELEASES FOLLOWING SALE OF ASSETS.

               In the event of a sale or other disposition of all of the assets
of any Guarantor, by way of merger, consolidation or otherwise, or a sale or
other disposition of all of the capital stock of any Guarantor (other than to
the Company or another Guarantor), or in the case the Company designates a
Domestic Restricted Subsidiary to be an Unrestricted Subsidiary in accordance
with this Indenture, then such Guarantor (in the event of a sale or other
disposition, by way of merger, consolidation or 



                                       72

<PAGE>   82

otherwise, of all of the capital stock of such Guarantor) or the corporation
acquiring the property (in the event of a sale or other disposition of all or
substantially all of the assets of such Guarantor) shall be released and
relieved of any obligations under its Note Guarantee; provided that the Net
Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of this Indenture, including without limitation Section
4.10 hereof. Upon delivery by the Issuers to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Issuers in accordance with the applicable provisions
of this Indenture, including without limitation Section 4.10 hereof, the Trustee
shall execute any documents reasonably required in order to evidence the release
of any Guarantor from its obligations under its Note Guarantee.

               Any Guarantor not released from its obligations under its Note
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other obligations of any Guarantor under this Indenture
as provided in this Article 10.

                                   ARTICLE 12.

EACH PERSON TO WHOM THIS NOTE OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF
THIS NOTE OR ANY INTEREST HEREIN WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE
HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING
TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE. AS
USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON"
HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES
ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

               Capitalized terms used herein shall have the meanings assigned to
them in the Indenture referred to below unless otherwise indicated.

               1.   INTEREST. UNICCO Service Company, a Massachusetts business
trust (the "Company"), and UNICCO Finance Corp., a Delaware corporation
("Finance" and, together with the Company, the "Issuers"), promise to pay
interest on the principal amount of this Note at 9 7/8% per annum from October
17, 1997 until maturity and shall pay the Liquidated Damages payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Issuers
will pay interest and Liquidated Damages semi-annually on April 15 and October
15 of each year, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"). Interest on the Notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
April 15, 1998. The Issuers shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 1% per annum in excess of the
rate then in effect; they shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest
and Liquidated Damages (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

               2.   METHOD OF PAYMENT. The Issuers will pay interest on the
Notes (except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the April 1 or October 1
next preceding the Interest Payment Date, even if such Notes are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest. The Notes
will be payable as to principal, premium and Liquidated Damages, if any, and
interest at the office or agency of the Issuers maintained for such purpose
within or without the City and State of New York, or, at the option of the
Issuers, payment of interest and Liquidated Damages may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages on, all Global Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Issuers or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

               3.   PAYING AGENT AND REGISTRAR. Initially, State Street Bank and
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuers may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

               4.   INDENTURE. The Issuers issued the Notes under an Indenture
dated as of October 17, 1997 (the "Indenture") among the Issuers, the guarantor
named on the signature pages thereto (the "Guarantors") and the Trustee. 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, as amended (15
U.S. Code ss.ss. 77aaa-77bbbb) (the "TIA"). The Notes are subject to all such
terms, and Holders are referred to the Indenture and the TIA for a statement of
such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are general, unsecured obligations of the Issuers limited
to $150.0 million in aggregate principal amount.

               5.   OPTIONAL REDEMPTION.

               (a)  Except as set forth in subparagraph (b) of this Paragraph 5,
the Notes shall not be redeemable at the Issuers' option prior to October 15,
2002. Thereafter, the Notes shall be subject to redemption at any time at the
option of the Issuers, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages,
if any, thereon to the applicable redemption date, if redeemed during the
twelve-month period beginning on October 15 of the years indicated below:

    YEAR                                                        PERCENTAGE
    ----                                                        ----------
    
    2002........................................................  104.94%
    2003........................................................  103.29%
    2004........................................................  101.65%
    2005 and thereafter.........................................  100.00%

               (b)  Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, prior to October 15, 2002, the Issuers may redeem up to an
aggregate of $33.0 million in principal amount of Notes at a redemption price of
109.875% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the redemption date, with the net cash
proceeds of an initial public offering of common equity of the Company; provided
that (i) at least $72.0 million in principal amount of Notes remains outstanding
immediately after the occurrence of such redemption and (ii) notice of such
redemption shall be given within 90 days of the date of the consummation of such
initial public offering.

               6.   MANDATORY REDEMPTION.

               Except as set forth in paragraph 7 below, the Issuers shall not
be required to make mandatory redemption payments with respect to the Notes.

               7. REPURCHASE AT OPTION OF HOLDER.


                                      A1-4
<PAGE>   91
               (a)  Upon the occurrence of a Change of Control, the Issuers
shall be obligated to make an offer (a "Change of Control Offer") to each Holder
of Notes to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Notes at an offer price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following a Change of Control, the Issuers shall mail
a notice to each Holder setting forth the procedures governing the Change of
Control Offer as required by the Indenture.

               (b)  If the Company or any of its Restricted Subsidiaries
consummates an Asset Sale, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $5 million, the Issuers shall commence an
offer to all Holders of Notes (an "Asset Sale Offer") pursuant to Section 3.09
of the Indenture to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase in accordance
with the procedures set forth in the Indenture. To the extent that the aggregate
amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Company may use any remaining Excess Proceeds for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

               8.   NOTICE OF REDEMPTION. Notice of redemption will be mailed by
first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Notes to be redeemed at its registered
address. Notes in denominations larger than $1,000 may be redeemed in part but
only in whole multiples of $1,000, unless all of the Notes held by a Holder are
to be redeemed. On and after the redemption date interest ceases to accrue on
Notes or portions thereof called for redemption.

               9.   DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Issuers may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Issuers need not
exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, the Issuers need not exchange or register the transfer of any Notes
for a period of 15 days before a selection of Notes to be redeemed or during the
period between a record date and the corresponding Interest Payment Date.

               10.  SUBORDINATION. Each Holder by accepting a Note agrees that
the payment of principal of and premium, interest and Liquidated Damages, if
any, on each Note is subordinated in right of payment, to the extent and in the
manner provided in Article 10 of the Indenture, to the prior payment in full of
all Senior Debt of the Issuers (whether outstanding on the date of the Indenture
or thereafter incurred, assumed or guaranteed), and the subordination is for the
benefit of the holders of such Senior Debt.

               11.  PERSONS DEEMED OWNERS. The registered Holder of a Note may
be treated as its owner for all purposes.

               12.  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture, the Note Guarantees or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding, and any existing default or compliance
with any provision of the Indenture, the Notes or the Note Guarantees may be
waived with the consent of the Holders of a majority in principal amount of the
then outstanding Notes. Without the consent of any Holder of Notes, the Issuers,
the Company's Restricted Subsidiaries and the Trustee may amend or supplement
the Indenture, the Notes or the Note Guarantees to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Company's, UNICCO
Finance's or any Restricted Subsidiary's obligations to Holders of the Notes in
case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA.

               13.  DEFAULTS AND REMEDIES. Events of Default include: (i)
default for 30 days in the payment when due of interest on, or Liquidated
Damages, if any, with respect to, the Notes (whether or not prohibited by
Article 10 of the Indenture); (ii) default in payment when due of principal of
or premium, if any, on the Notes (whether or not prohibited by Article 10 of the
Indenture); (iii) failure by the Issuers to comply with Section 4.07, 4.09,
4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Issuers for 60 days
after written notice by the Trustee or the Holders of at least 25% in principal
amount of the then outstanding Notes to comply with any of their other
agreements in the Indenture or the Notes; (v) default under certain other
agreements relating to Indebtedness of the Company which default (a) is caused
by a failure to pay principal of or premium, if any, or interest on such
Indebtedness on the date of such default (a "Payment Default") or (b) results in
the acceleration of such Indebtedness prior to its express maturity and, in each
case, the principal amount of any such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$5.0 million or more; (vi) failure by the Company, UNICCO Finance or any of the
Company's Restricted Subsidiaries to pay final judgments aggregating in excess
of $2.0 million and either (a) any creditor commences enforcement proceedings
upon any such judgment or (b) such judgments are not paid, discharged or stayed
for a period of 45 days; (vii) except as permitted by the Indenture, any
guarantee of the Notes shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or any Restricted Subsidiary, or any Person acting on behalf of any
Restricted Subsidiary, shall deny or disaffirm its obligations under its
guarantee; (viii) the Refinancing shall not have been consummated by 11:59 p.m.,
New York City time, on the date of the Indenture; and (ix) certain events of
bankruptcy or insolvency with respect to the Company, UNICCO Finance or any of
the Company's Restricted Subsidiaries. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, all outstanding Notes
will become due and payable without further action or notice. Holders of the
Notes may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of Default




                                      A1-6
<PAGE>   93

relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the Notes.
The Issuers are required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Issuers are required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.

               14.  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Issuers or their Affiliates, and may otherwise deal
with the Issuers or their Affiliates, as if it were not the Trustee.

               15.  NO RECOURSE AGAINST OTHERS. A director, officer, employee,
trustee, incorporator or shareholder of either Issuer, as such, shall not have
any liability for any obligations of the Issuers or any of the Company's
Subsidiaries under the Notes, the Indenture, the Note Guarantees or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder 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.

               16.  AUTHENTICATION. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

               17.  ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder 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).

               18.  ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of October 17, 1997, among the Issuers and the parties named
on the signature pages thereof (the "Registration Rights Agreement").

               18.  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 and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

               The Issuers will furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to:

THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO
REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING
RESTRICTIONS.

               Capitalized terms used herein shall have the meanings assigned to
them in the Indenture referred to below unless otherwise indicated.

               1.   INTEREST. UNICCO Service Company, a Massachusetts business
trust (the "Company"), and UNICCO Finance Corp., a Delaware corporation
("Finance" and, together with the Company, the "Issuers"), promise to pay
interest on the principal amount of this Note at 9 7/8% per annum from October
17, 1997 until maturity and shall pay the Liquidated Damages payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Issuers

15 of each year, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"). Interest on the Notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
April 15, 1998. The Issuers shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 1% per annum in excess of the
rate then in effect; they shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest
and Liquidated Damages (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

               Until this Regulation S Temporary Global Note is exchanged for
one or more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Notes under the Indenture.

               2. METHOD OF PAYMENT. The Issuers will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the April 1 or October 1
next preceding the Interest Payment Date, even if such Notes are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest. The Notes
will be payable as to principal, premium and Liquidated Damages, if any, and
interest at the office or agency of the Issuers maintained for such purpose
within or without the City and State of New York, or, at the option of the
Issuers, payment of interest and Liquidated Damages may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages on, all Global Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Issuers or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

               3.   PAYING AGENT AND REGISTRAR. Initially, State Street Bank and
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuers may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

               4.   INDENTURE. The Issuers issued the Notes under an Indenture
dated as of October 17, 1997 (the "Indenture") among the Issuers, the guarantor
named on the signature pages thereto (the "Guarantors") and the Trustee. 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, as amended (15
U.S. Code ss.ss. 77aaa-77bbbb) (the "TIA"). The Notes are subject to all such
terms, and Holders are referred to the Indenture and the TIA for a statement of
such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are general, unsecured obligations of the Issuers limited
to $150.0 million in aggregate principal amount.

               5.   OPTIONAL REDEMPTION.

               (a)  Except as set forth in subparagraph (b) of this Paragraph 5,
the Notes shall not be redeemable at the Issuers' option prior to October 15,
2002. Thereafter, the Notes shall be subject to redemption at any time at the
option of the Issuers, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages,
if any, thereon to the applicable redemption date, if redeemed during the
twelve-month period beginning on October 15 of the years indicated below:

    2004........................................................  101.65%
    2005 and thereafter.........................................  100.00%

               (b)  Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, prior to October 15, 2002, the Issuers may redeem up to an
aggregate of $33.0 million in principal amount of Notes at a redemption price of
109.875% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the redemption date, with the net cash
proceeds of an initial public offering of common equity of the Company; provided
that (i) at least $72.0 million in principal amount of Notes remains outstanding
immediately after the occurrence of such redemption and (ii) notice of such
redemption shall be given within 90 days of the date of the consummation of such
initial public offering.

               6.   MANDATORY REDEMPTION.

                  Except as set forth in paragraph 7 below, the Issuers shall
not be required to make mandatory redemption payments with respect to the Notes.

               7.   REPURCHASE AT OPTION OF HOLDER.

               (a)  Upon the occurrence of a Change of Control, the Issuers
shall be obligated to make an offer (a "Change of Control Offer") to each Holder
of Notes to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Notes at an offer price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following a Change of Control, the Issuers shall mail
a notice to each Holder setting forth the procedures governing the Change of
Control Offer as required by the Indenture.

               (b)  If the Company or any of its Restricted Subsidiaries
consummates an Asset Sale, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $5 million, the Issuers shall commence an
offer to all Holders of Notes (an "Asset Sale Offer") pursuant to Section 3.09
of the Indenture to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase in accordance
with the procedures set forth in the Indenture. To the extent that the aggregate
amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Company may use any remaining Excess Proceeds for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

               8.   NOTICE OF REDEMPTION. Notice of redemption will be mailed by
first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Notes to be redeemed at its registered
address. Notes in denominations larger than $1,000 may be redeemed in part but
only in whole multiples of $1,000, unless all of the Notes held by a Holder are
to be




                                      A2-5
<PAGE>   102


redeemed. On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

               9.   DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Issuers may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Issuers need not
exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, the Issuers need not exchange or register the transfer of any Notes
for a period of 15 days before a selection of Notes to be redeemed or during the
period between a record date and the corresponding Interest Payment Date.

               This Regulation S Temporary Global Note is exchangeable in whole
or in part for one or more Global Notes only (i) on or after the termination of
the 40-day restricted period (as defined in Regulation S) and (ii) upon
presentation of certificates (accompanied by an Opinion of Counsel, if
applicable) required by Article 2 of the Indenture. Upon exchange of this
Regulation S Temporary Global Note for one or more Global Notes, the Trustee
shall cancel this Regulation S Temporary Global Note.

               10.  SUBORDINATION. Each Holder by accepting a Note agrees that
the payment of principal of and premium, interest and Liquidated Damages, if
any, on each Note is subordinated in right of payment, to the extent and in the
manner provided in Article 10 of the Indenture, to the prior payment in full of
all Senior Debt of the Issuers (whether outstanding on the date of the Indenture
or thereafter incurred, assumed or guaranteed), and the subordination is for the
benefit of the holders of such Senior Debt.

               11.  PERSONS DEEMED OWNERS. The registered Holder of a Note may
be treated as its owner for all purposes.

               12.  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture, the Note Guarantees or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding, and any existing default or compliance
with any provision of the Indenture, the Notes or the Note Guarantees may be
waived with the consent of the Holders of a majority in principal amount of the
then outstanding Notes. Without the consent of any Holder of Notes, the Issuers,
the Company's Restricted Subsidiaries and the Trustee may amend or supplement
the Indenture, the Notes or the Note Guarantees to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Company's, UNICCO
Finance's or any Restricted Subsidiary's obligations to Holders of the Notes in
case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA.

               13.  DEFAULTS AND REMEDIES. Events of Default include: (i)
default for 30 days in the payment when due of interest on, or Liquidated
Damages, if any, with respect to, the Notes 




                                      A2-6
<PAGE>   103

(whether or not prohibited by Article 10 of the Indenture); (ii) default in
payment when due of principal of or premium, if any, on the Notes (whether or
not prohibited by Article 10 of the Indenture); (iii) failure by the Issuers to
comply with Section 4.07, 4.09, 4.10, 4.15 or 5.01 of the Indenture; (iv)
failure by the Issuers for 60 days after written notice by the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes to
comply with any of their other agreements in the Indenture or the Notes; (v)
default under certain other agreements relating to Indebtedness of the Company
which default (a) is caused by a failure to pay principal of or premium, if any,
or interest on such Indebtedness on the date of such default (a "Payment
Default") or (b) results in the acceleration of such Indebtedness prior to its
express maturity and, in each case, the principal amount of any such
Indebtedness under which there has been a Payment Default or the maturity of
which has been so accelerated, aggregates $5.0 million or more; (vi) failure by
the Company, UNICCO Finance or any of the Company's Restricted Subsidiaries to
pay final judgments aggregating in excess of $2.0 million and either (a) any
creditor commences enforcement proceedings upon any such judgment or (b) such
judgments are not paid, discharged or stayed for a period of 45 days; (vii)
except as permitted by the Indenture, any guarantee of the Notes shall be held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Restricted Subsidiary, or any
Person acting on behalf of any Restricted Subsidiary, shall deny or disaffirm
its obligations under its guarantee; (viii) the Refinancing shall not have been
consummated by 11:59 p.m., New York City time, on the date of the Indenture; and
(ix) certain events of bankruptcy or insolvency with respect to the Company,
UNICCO Finance or any of the Company's Restricted Subsidiaries. If any Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare all the Notes to be
due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Notes will become due and payable without further action or notice.
Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. The Issuers are required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Issuers are required, upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

               14.  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Issuers or their Affiliates, and may otherwise deal
with the Issuers or their Affiliates, as if it were not the Trustee.

               15.  NO RECOURSE AGAINST OTHERS. A director, officer, employee,
trustee, incorporator or shareholder of either Issuer, as such, shall not have
any liability for any obligations of the Issuers or any of the Company's
Subsidiaries under the Notes, the Indenture, the Note Guarantees or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder 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.

              we confirm that:

                     1.     We understand that any subsequent transfer of the
Notes or any interest therein is subject to certain restrictions and conditions
set forth in the Indenture and the undersigned agrees to be bound by, and not to
resell, pledge or otherwise transfer the Notes or any interest therein except in
compliance with, such restrictions and conditions and the United States

                     2.     We understand that the offer and sale of the Notes
have not been registered under the Securities Act, and that the Notes and any
interest therein may not be offered or sold except as permitted in the following

are acting as hereinafter stated, that if we should sell the Notes or any
interest therein, we will do so only (A) to the Issuers or any Restricted
Subsidiary thereof, (B) in accordance with Rule 144A under the Securities Act to
a "qualified institutional buyer" (as defined therein), (c) to an institutional
"accredited investor" (as defined below) that, prior to such transfer, furnishes
(or has furnished on its behalf by a U.S. broker-dealer) to you and to the

outside the United States in accordance with Rule 904 of Regulation S under the
Securities Act, (E) pursuant to the provisions of Rule 144(k) under the
Securities Act or (F) pursuant to an effective registration statement under the

meeting the requirements of clauses (A) through (E) of this paragraph a notice
advising such purchaser that resales thereof are restricted as stated herein.

                     3.     We understand that, on any proposed resale of the
Notes or beneficial interest therein, we will be required to furnish to you and
the Issuers such certifications, legal opinions and other information as you and
the Issuers may reasonably require to confirm that the proposed sale complies
with the foregoing restrictions. We further understand that the Notes purchased
by us will bear a legend to the foregoing effect. We further understand that any
subsequent transfer by us of the Notes or beneficial interest therein acquired

and we and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.

                     5.     We are acquiring the Notes or beneficial interest
therein purchased by us for our own account or for one or more accounts (each of
which is an institutional "accredited investor") as to each of which we exercise
sole investment discretion.

              You and the Issuers are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested

                     authenticated and delivered by the Trustee and to the

                            lawful, and all other obligations of the Issuers to
                            the Holders or the Trustee hereunder or thereunder
                            will 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 any of such other

                     Issuers, protest, notice and all demands whatsoever.


              (d)    This Note Guarantee shall not be discharged except by
                     complete performance of the Obligations contained in the

                     acting in relation to either the Issuers or the Guarantors,
                     any amount paid by either to the Trustee or such Holder,
                     this Note Guarantee, to the extent theretofore discharged,
                     shall be reinstated in full force and effect.


              (f)    The Guaranteeing Restricted Subsidiary shall not be
                     entitled to any right of subrogation in relation to the
                     Holders in respect of any obligations guaranteed hereby

                     or other prohibition preventing such acceleration in
                     respect of the Obligations guaranteed hereby, and (y) in
                     the event of any declaration of acceleration of such
                     Obligations as provided in Article 6 of the Indenture, such
                     Obligations (whether or not due

              (h)    The Guarantors shall have the right to seek contribution
                     from any non-paying Guarantor so long as the exercise of
                     such right does not impair the rights of the Holders under
                     the Note Guarantee.


              (i)    Pursuant to Section 11.03 of the Indenture, after giving
                     effect to any maximum amount and any other contingent and
                     fixed liabilities that are relevant under any applicable

                     Guarantor under Article 11 of the Indenture the Obligations
                     of the Guarantors shall be limited to the maximum amount as
                     shall result in the Obligations of such Guarantor under its
                     Note Guarantee not constituting a fraudulent transfer or
                     conveyance.

              3      EXECUTION AND DELIVERY. Each Guaranteeing Restricted
Subsidiary agrees that the Note Guarantees shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Note
Guarantee.

              4.     GUARANTEEING RESTRICTED SUBSIDIARY MAY CONSOLIDATE, ETC. ON
CERTAIN TERMS.

       (a)    The Guaranteeing Restricted Subsidiary may not consolidate with or
              merge with or into (whether or not such Guarantor is the surviving
              Person) another corporation, Person or entity whether or not
              affiliated with such Guarantor unless:

              (i)    subject to Section 11.05 of the Indenture, the Person
                     formed by or surviving any such consolidation or merger (if
                     other than a Guarantor or the Issuers) unconditionally
                     assumes all the obligations of such Guarantor, pursuant to
                     a supplemental indenture in form and substance reasonably
                     satisfactory to the Trustee, under the Notes, the Indenture
                     and the Note Guarantee on the terms set forth herein or
                     therein; and

              (ii)   immediately after giving effect to such transaction, no
                     Default or Event of Default exists.

       (b)    In case of any such consolidation, merger, sale or conveyance and
              upon the assumption by the successor corporation, by supplemental
              indenture, executed and delivered to the Trustee and satisfactory
              in form to the Trustee, of the Note Guarantee endorsed upon the
              Notes and the due and punctual performance of all of the covenants
              and conditions of the Indenture to be performed by the Guarantor,
              such successor corporation shall succeed to and be substituted for
              the Guarantor with the same effect as if it had been named herein
              as a Guarantor. Such successor corporation thereupon may cause to
              be signed any or all of the Note Guarantees to be endorsed upon
              all of the Notes issuable hereunder which theretofore shall not
              have been signed by the Issuers and delivered to the Trustee. All
              the Note Guarantees so issued shall in all respects have the same
              legal 




                                      F-3

              theretofore and thereafter issued in accordance with the terms of
              the Indenture as though all of such Note Guarantees had been
              issued at the date of the execution hereof.

              (c)    Except as set forth in Articles 4 and 5 of the Indenture,
and notwithstanding clauses (a) and (b) above, nothing contained in the
Indenture or in any of the Notes shall prevent any consolidation or merger of a
Guarantor with or into the Issuers or another Guarantor, or shall prevent any
sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to the Issuers or another Guarantor.

              5.     RELEASES.

       (a)    In the event of a sale or other disposition of all of the assets
              of any Guarantor, by way of merger, consolidation or otherwise, or
              a sale or other disposition of all of the capital stock of any
              Guarantor (other than to the Company or another Guarantor), or in
              the case the Company designates a Domestic Restricted Subsidiary
              to be an Unrestricted Subsidiary in accordance with the Indenture,
              then such Guarantor (in the event of a sale or other disposition,
              by way of merger, consolidation or otherwise, of all of the
              capital stock of such Guarantor) or the corporation acquiring the
              property (in the event of a sale or other disposition of all or
              substantially all of the assets of such Guarantor) shall be
              released and relieved of any obligations under its Note Guarantee;
              provided that the Net Proceeds of such sale or other disposition
              are applied in accordance with the applicable provisions of the
              Indenture, including without limitation Section 4.10 of the
              Indenture. Upon delivery by the Issuers to the Trustee of an
              Officers' Certificate and an Opinion of Counsel to the effect that
              such sale or other disposition was made by the Issuers in
              accordance with the provisions of the Indenture, including without
              limitation Section 4.10 of the Indenture, the Trustee shall
              execute any documents reasonably required in order to evidence the
              release of any Guarantor from its obligations under its Note
              Guarantee.

       (b)    Any Guarantor not released from its obligations under its Note
              Guarantee shall remain liable for the full amount of principal of
              and interest on the Notes and for the other obligations of any
              Guarantor under the Indenture as provided in Article 10 of the
              Indenture.

              6.     NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, trustee, incorporator, shareholder or agent of the
Guaranteeing Restricted Subsidiary, as such, shall have any liability for any
obligations of the Issuers or any Guaranteeing Restricted Subsidiary under the
Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for
any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for
issuance of the Notes. Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the Commission that such
a waiver is against public policy.

              7.     NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF
NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO 




                                      F-4

THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.

              8.     COUNTERPARTS. The parties may sign any number of copies of
this Supplemental Indenture. Each signed copy shall be an original, but all of
them together represent the same agreement.

              9.     EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof.

              10.    THE TRUSTEE. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Restricted Subsidiary
and the Issuers.

SECTION 2.        SECURITIES SUBJECT TO THIS AGREEMENT

         (a) TRANSFER RESTRICTED SECURITIES. The securities entitled to the
benefits of this Agreement are the Transfer Restricted Securities.

         (b) HOLDERS OF TRANSFER RESTRICTED SECURITIES. A Person is deemed to be
a holder of Transfer Restricted Securities (each, a "HOLDER") whenever such
Person owns Transfer Restricted Securities.


SECTION 3.        REGISTERED EXCHANGE OFFER

         (a) Unless the Exchange Offer shall not be permissible under applicable
law or Commission policy (after the procedures set forth in Section 6(a) below
have been complied with), the Issuers and the Guarantors shall (i) cause to be
filed with the Commission as soon as practicable after the Closing Date, but in
no event later than 45 days after the Closing Date, the Exchange Offer
Registration Statement, (ii) use their best efforts to cause such Exchange Offer
Registration Statement to become effective at the earliest possible time, but in
no event later than 120 days after the Closing Date, (iii) in connection with
the foregoing, file (A) all pre-effective amendments to such Exchange Offer
Registration Statement as may be necessary in order to cause such Exchange Offer
Registration Statement to become effective, (B) if applicable, a post-effective
amendment to such Exchange Offer Registration Statement pursuant to Rule 430A
under the Act and (C) cause all necessary filings in connection with the
registration and qualification of the Series B Notes to be made under the Blue
Sky laws of such jurisdictions as are necessary to permit Consummation of the
Exchange Offer, and (iv) upon the effectiveness of such Exchange Offer
Registration Statement, commence and Consummate the Exchange Offer. The Exchange
Offer shall be on the appropriate form permitting registration of the Series B
Notes to be offered in exchange for the Transfer Restricted Securities and to
permit resales of Notes held by Broker-Dealers as contemplated by Section 3(c)
below.

         (b) The Issuers shall cause the Exchange Offer Registration Statement
to be effective continuously and shall keep the Exchange Offer open for a period
of not less than the minimum period


                                        3



<PAGE>   5



required under applicable federal and state securities laws to Consummate the
Exchange Offer; provided, however, that in no event shall such period be less
than 20 business days. The Issuers shall cause the Exchange Offer to comply with
all applicable federal and state securities laws. No securities other than the
Notes shall be included in the Exchange Offer Registration Statement. The
Issuers shall use their best efforts to cause the Exchange Offer to be
Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30
business days thereafter.

         (c) The Issuers shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Series A Notes that are Transfer
Restricted Securities and that were acquired for its own account as a result of
market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Issuers) may exchange such
Series A Notes pursuant to the Exchange Offer; however, such Broker-Dealer may
be deemed to be an "underwriter" within the meaning of the Act and must,
therefore, deliver a prospectus meeting the requirements of the Act in
connection with any resales of the Series B Notes received by such Broker-Dealer
in the Exchange Offer, which prospectus delivery requirement may be satisfied by
the delivery by such Broker-Dealer of the Prospectus contained in the Exchange
Offer Registration Statement. Such "Plan of Distribution" section shall also
contain all other information with respect to such resales by Broker-Dealers
that the Commission may require in order to permit such resales pursuant
thereto, but such "Plan of Distribution" shall not name any such Broker-Dealer
or disclose the amount of Notes held by any such Broker-Dealer except to the
extent required by the Commission as a result of a change in policy after the
date of this Agreement.

         If requested by any Broker-Dealer, the Issuers and the Guarantors shall
use their best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented and amended as required by the provisions
of Section 6(c) below to the extent necessary to ensure that it is available for
resales of Notes acquired by Broker-Dealers for their own accounts as a result
of market-making activities or other trading activities, and to ensure that it
conforms with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of one year from the date on which the Exchange Offer Registration
Statement is declared effective.

         The Issuers shall provide sufficient copies of the latest version of
such Prospectus to Broker-Dealers promptly upon request at any time during such
one-year period in order to facilitate such resales.


SECTION 4.        SHELF REGISTRATION

         (a) SHELF REGISTRATION. If (i) the Issuers and the Guarantors are not
required to file an Exchange Offer Registration Statement or permitted to
consummate the Exchange Offer because the Exchange Offer is not permitted by
applicable law or Commission policy (after the procedures set forth in Section
6(a) below have been complied with) or (ii) any Holder of Transfer Restricted
Securities notifies the Company on or prior to the 20th business day following
the Consummation of the Exchange Offer (A) that such Holder is prohibited by
applicable law or Commission policy from participating in the Exchange Offer, or
(B) that such Holder may not resell the Series B Notes acquired by it in the
Exchange Offer to the public without delivering a prospectus and that the
Prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such Holder, or (C) that such
Holder is a Broker-Dealer and holds Series A Notes acquired directly from the
Issuers or one of their affiliates, then the Issuers and the Guarantors shall:


                                        4



<PAGE>   6




                (x) Use their best efforts to file a shelf registration
      statement with the Commission pursuant to Rule 415 under the Act, which
      may be an amendment to the Exchange Offer Registration Statement (in any
      event, the "SHELF REGISTRATION STATEMENT") on or prior to the earliest to
      occur of (1) the 45th day after the date on which the Issuers and the
      Guarantors determine that they are not required to file the Exchange Offer
      Registration Statement and (2) the 45th day after the date on which the
      Issuers receive notice from a Holder of Transfer Restricted Securities as
      contemplated by clause (ii) above (such earliest date being the "SHELF
      FILING DEADLINE"), which Shelf Registration Statement shall provide for
      resales of all Transfer Restricted Securities the Holders of which shall
      have provided the information required pursuant to Section 4(b) hereof;
      and

                (y) Cause such Shelf Registration Statement to be declared
      effective by the Commission on or prior to the 120th day after the Shelf
      Filing Deadline.

The Issuers and the Guarantors shall use their best efforts to keep such Shelf
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Sections 6(b) and (c) hereof to the extent
necessary to ensure that it is available for resales of Notes by the Holders of
Transfer Restricted Securities entitled to the benefit of this Section 4(a), and
to ensure that it conforms with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period until the earlier to occur of (i) the date all of the
Transfer Restricted Securities registered under such Shelf Registration
Statement have been sold and (ii) the second anniversary following the Closing
Date.

         (b) PROVISION BY HOLDERS OF CERTAIN INFORMATION IN CONNECTION WITH THE
SHELF REGISTRATION STATEMENT. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Issuers in writing, within 20 business days after receipt of a request
therefor, such information as the Issuers may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. No Holder of Transfer Restricted Securities shall
be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until
such Holder shall have used its best efforts to provide all such reasonably
requested information. Each Holder of Notes as to which any Shelf Registration
Statement is being effected, by its participation in the Shelf Registration
Statement, shall be deemed to agree to furnish promptly to the Issuers all
information required to be disclosed in order to make the information previously
furnished to the Issuers by such Holder not materially misleading.


SECTION 5.        LIQUIDATED DAMAGES

         If (a) any of the Registration Statements required by this Agreement is
not filed with the Commission on or prior to the date specified for such filing
in this Agreement, (b) any of such Registration Statements has not been declared
effective by the Commission on or prior to the date specified for such
effectiveness in this Agreement (the "EFFECTIVENESS TARGET DATE"), (c) the
Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (d) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself immediately declared effective (each such


                                        5



<PAGE>   7



event referred to in clauses (a) through (d), a "REGISTRATION DEFAULT"), the
Issuers and the Guarantors hereby jointly and severally agree to pay liquidated
damages to each Holder of Transfer Restricted Securities affected by such
Registration Default with respect to the first 90-day period immediately
following the occurrence of such Registration Default, in an amount equal to
$.05 per week per $1,000 principal amount of Transfer Restricted Securities held
by such Holder. The amount of the liquidated damages shall increase by an
additional $.05 per week per $1,000 principal amount of Transfer Restricted
Securities with respect to each subsequent 90-day period until all Registration
Defaults affecting such Holder have been cured, up to a maximum amount of
liquidated damages of $.50 per week per $1,000 principal amount of Transfer
Restricted Securities. All accrued liquidated damages shall be paid by the
Issuers on each Damages Payment Date to Record Holders by wire transfer of
immediately available funds or by federal funds check and to Holders of
Certificated Securities by wire transfers to the accounts specified by them or
by mailing checks to their registered addresses if no such accounts have been
specified on each Damages Payment Date, as provided in the Indenture. Following
the cure of all Registration Defaults relating to any particular Transfer
Restricted Securities, the accrual of liquidated damages with respect to such
Transfer Restricted Securities will cease.

           All obligations of the Issuers and the Guarantors set forth in the
preceding paragraph that are outstanding with respect to any Transfer Restricted
Security at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such
security shall have been satisfied in full.


SECTION 6.        REGISTRATION PROCEDURES

         (a) EXCHANGE OFFER REGISTRATION STATEMENT. In connection with the
Exchange Offer, the Issuers and the Guarantors shall comply with all of the
provisions of Section 6(c) below, shall use their best efforts to effect such
exchange to permit the sale of Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and
shall comply with all of the following provisions:

             (i) If in the reasonable opinion of counsel to the Issuers there
      is a question as to whether the Exchange Offer is permitted by applicable
      law, the Issuers and the Guarantors hereby agree to seek a no-action
      letter or other favorable decision from the Commission allowing the
      Issuers and the Guarantors to Consummate an Exchange Offer for such Series
      A Notes. Each of the Issuers and the Guarantors hereby agrees to pursue
      the issuance of such a decision to the Commission staff level but shall
      not be required to take commercially unreasonable action to effect a
      change of Commission policy. Each of the Issuers and the Guarantors hereby
      agrees, however, to (A) participate in telephonic conferences with the
      Commission, (B) deliver to the Commission staff an analysis prepared by
      counsel to the Issuers setting forth the legal bases, if any, upon which
      such counsel has concluded that such an Exchange Offer should be permitted
      and (C) diligently pursue a resolution (which need not be favorable) by
      the Commission staff of such submission.

             (ii) As a condition to its participation in the Exchange Offer
      pursuant to the terms of this Agreement, each Holder of Transfer
      Restricted Securities shall furnish, upon the request of the Issuers,
      prior to the Consummation thereof, a written representation to the Issuers
      (which may be contained in the letter of transmittal contemplated by the
      Exchange Offer Registration Statement) to the effect that (A) it is not an
      affiliate of either of the Issuers or any Guarantor, (B) it is not engaged
      in, and does not intend to engage in, and has no arrangement or
      understanding with any person to


                                        6

      participate in, a distribution of the Series B Notes to be issued in the
      Exchange Offer and (C) it is acquiring the Series B Notes in its ordinary
      course of business. In addition, all such Holders of Transfer Restricted
      Securities shall otherwise cooperate in the Issuers' preparations for the
      Exchange Offer. Each Holder shall be deemed to acknowledge and agree that
      any Broker-Dealer and any such Holder using the Exchange Offer to
      participate in a distribution of the securities to be acquired in the
      Exchange Offer (1) could not under Commission policy as in effect on the
      date of this Agreement rely on the position of the Commission enunciated
      in MORGAN STANLEY AND CO., INC. (available June 5, 1991) and EXXON CAPITAL
      HOLDINGS CORPORATION (available May 13, 1988), as interpreted in the
      Commission's letter to Shearman & Sterling dated July 2, 1993, and similar
      no-action letters (including any no-action letter obtained pursuant to
      clause (i) above), and (2) must comply with the registration and
      prospectus delivery requirements of the Act in connection with a secondary
      resale transaction and that such a secondary resale transaction should be
      covered by an effective registration statement containing the selling
      security holder information required by Item 507 or 508, as applicable, of
      Regulation S-K if the resales are of Series B Notes obtained by such
      Holder in exchange for Series A Notes acquired by such Holder directly
      from the Issuers.

             (iii) Prior to effectiveness of the Exchange Offer Registration
      Statement, the Issuers and the Guarantors shall provide a supplemental
      letter to the Commission (A) stating that the Issuers and the Guarantors
      are registering the Exchange Offer in reliance on the position of the
      Commission enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May
      13, 1988), MORGAN STANLEY AND CO., INC. (available June 5, 1991) and, if
      applicable, any no-action letter obtained pursuant to clause (i) above and
      (B) including a representation that neither of the Issuers nor any of the
      Guarantors has entered into any arrangement or understanding with any
      Person to distribute the Series B Notes to be received in the Exchange
      Offer and that, to the best of the Issuers' and the Guarantors'
      information and belief, each Holder participating in the Exchange Offer is
      acquiring the Series B Notes in its ordinary course of business and has no
      arrangement or understanding with any Person to participate in the
      distribution of the Series B Notes received in the Exchange Offer.

         (b) SHELF REGISTRATION STATEMENT. In connection with the Shelf
Registration Statement, the Issuers and the Guarantors shall comply with all the
provisions of Section 6(c) below and shall use their best efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold
in accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Issuers will within the time periods specified herein
prepare and file with the Commission a Registration Statement relating to the
registration on any appropriate form under the Act, which form shall be
available for the sale of the Transfer Restricted Securities in accordance with
the intended method or methods of distribution thereof.

         (c) GENERAL PROVISIONS. In connection with any Registration Statement
and any Prospectus required by this Agreement to permit the sale or resale of
Transfer Restricted Securities (including, without limitation, any Registration
Statement and the related Prospectus required to permit resales of Notes by
Broker-Dealers), the Issuers and the Guarantors shall:

             (i) use their best efforts to keep such Registration Statement
      continuously effective and provide all requisite financial statements
      (including, if required by the Act or any regulation thereunder, financial
      statements of the Guarantors) for the period specified in Section 3 or 4
      hereof, as applicable; upon the occurrence of any event that would cause
      any such Registration Statement or the Prospectus contained therein (A) to
      contain a material misstatement or omission or (B) not to be effective and
      usable for resale of Transfer Restricted Securities during the period
      required by this


                                        7



<PAGE>   9



      Agreement, the Issuers shall file promptly an appropriate amendment to
      such Registration Statement, in the case of clause (A), correcting any
      such misstatement or omission, and, in the case of either clause (A) or
      (B), use their best efforts to cause such amendment to be declared
      effective and such Registration Statement and the related Prospectus to
      become usable for their intended purpose(s) as soon as practicable
      thereafter;

              (ii) prepare and file with the Commission such amendments and
      post-effective amendments to the Registration Statement as may be
      necessary to keep the Registration Statement effective for the applicable
      period set forth in Section 3 or 4 hereof, as applicable, or such shorter
      period as will terminate when all Transfer Restricted Securities covered
      by such Registration Statement have been sold; cause the Prospectus to be
      supplemented by any required Prospectus supplement, and as so supplemented
      to be filed pursuant to Rule 424 under the Act, and to comply fully with
      the applicable provisions of Rules 424 and 430A under the Act in a timely
      manner; and comply with the provisions of the Act with respect to the
      disposition of all securities covered by such Registration Statement
      during the applicable period in accordance with the intended method or
      methods of distribution by the sellers thereof set forth in such
      Registration Statement or supplement to the Prospectus;

              (iii) advise the underwriter(s), if any, and selling Holders (in
      the case of a Shelf Registration Statement) promptly and, if requested by
      such Persons, to confirm such advice in writing, (A) when the Prospectus
      or any Prospectus supplement or post-effective amendment has been filed,
      and, with respect to any Registration Statement or any post-effective
      amendment thereto, when the same has become effective, (B) of any request
      by the Commission for amendments to the Registration Statement or
      amendments or supplements to the Prospectus or for additional information
      relating thereto, (C) of the issuance by the Commission of any stop order
      suspending the effectiveness of the Registration Statement under the Act
      or of the suspension by any state securities commission of the
      qualification of the Transfer Restricted Securities for offering or sale
      in any jurisdiction, or the initiation of any proceeding for any of the
      preceding purposes, (D) of the existence of any fact or the happening of
      any event that makes any statement of a material fact made in the
      Registration Statement, the Prospectus, any amendment or supplement
      thereto, or any document incorporated by reference therein untrue, or that
      requires the making of any additions to or changes in the Registration
      Statement in order to make the statements therein not misleading, or that
      requires the making of any additions to or changes in the Prospectus in
      order to make the statements therein, in light of the circumstances under
      which they were made, not misleading. If at any time the Commission shall
      issue any stop order suspending the effectiveness of the Registration
      Statement, or any state securities commission or other regulatory
      authority shall issue an order suspending the qualification or exemption
      from qualification of the Transfer Restricted Securities under state
      securities or Blue Sky laws, the Issuers and the Guarantors shall use
      their reasonable best efforts to obtain the withdrawal or lifting of such
      order at the earliest possible time;

              (iv) furnish to each of the selling Holders and each of the
      underwriter(s), if any, before filing with the Commission, copies of any
      Shelf Registration Statement or any Prospectus included therein or any
      amendments or supplements to any such Registration Statement or Prospectus
      (including all documents incorporated by reference after the initial
      filing of such Registration Statement), which documents will be subject to
      the review and comment of such Holders and underwriter(s), if any, for a
      period of at least five business days, and the Issuers will not file any
      such Registration Statement or Prospectus or any amendment or supplement
      to any such Registration Statement or Prospectus (including all such
      documents incorporated by reference) to which a selling Holder of Transfer
      Restricted Securities covered by such Registration Statement or the


                                        8



<PAGE>   10



      underwriter(s), if any, shall reasonably object within five business days
      after the receipt thereof. An objection from a selling Holder or
      underwriter, if any, shall be deemed to be reasonable if such Registration
      Statement, amendment, Prospectus or supplement, as applicable, as proposed
      to be filed, contains a material misstatement or omission or fails to
      comply with the applicable requirements of the Act;

                (v) promptly prior to the filing of any document that is to be
      incorporated by reference into a Shelf Registration Statement or
      Prospectus, provide copies of such document to the selling Holders and to
      the underwriter(s), if any, make the Issuers' representatives available
      (and representatives of the Guarantors) for discussion of such document
      and other customary due diligence matters, and include such information in
      such document prior to the filing thereof as such selling Holders or
      underwriter(s), if any, reasonably may request;

                (vi) make available at reasonable times for inspection by the
      selling Holders, any underwriter participating in any disposition pursuant
      to such Registration Statement, and any attorney or accountant retained by
      such selling Holders or any of the underwriter(s), all financial and other
      records, pertinent corporate documents and properties of the Issuers and
      the Guarantors and cause the Issuers' and the Guarantors' officers,
      directors and employees to supply all information reasonably requested by
      any such Holder, underwriter, attorney or accountant in connection with
      such Registration Statement subsequent to the filing thereof and prior to
      its effectiveness;

                (vii) if requested by any selling Holders or the underwriter(s),
      if any, promptly include in any Registration Statement or Prospectus,
      pursuant to a supplement or post-effective amendment if necessary, such
      information as such selling Holders and underwriter(s), if any, may
      reasonably request to have included therein, including, without
      limitation, information relating to the "Plan of Distribution" of the
      Transfer Restricted Securities, information with respect to the principal
      amount of Transfer Restricted Securities being sold to such
      underwriter(s), the purchase price being paid therefor and any other terms
      of the offering of the Transfer Restricted Securities to be sold in such
      offering; and make all required filings of such Prospectus supplement or
      post-effective amendment as soon as practicable after the Issuers are
      notified of the matters to be included in such Prospectus supplement or
      post-effective amendment;

                (viii) furnish to each selling Holder and each of the
      underwriter(s), if any, without charge, at least one copy of the Shelf
      Registration Statement, as first filed with the Commission, and of each
      amendment thereto, including all documents incorporated by reference
      therein and all exhibits (including exhibits incorporated therein by
      reference);

                (ix) deliver to each selling Holder and each of the
      underwriter(s), if any, without charge, as many copies of the Prospectus
      (including each preliminary prospectus) and any amendment or supplement
      thereto as such Persons reasonably may request; the Issuers and the
      Guarantors hereby consent to the use of the Prospectus and any amendment
      or supplement thereto by each of the selling Holders and each of the
      underwriter(s), if any, in connection with the offering and the sale of
      the Transfer Restricted Securities covered by the Prospectus or any
      amendment or supplement thereto;

                (x) enter into such agreements (including an underwriting
      agreement on customary terms), and make such representations and
      warranties, and take all such other actions in connection therewith in
      order to expedite or facilitate the disposition of the Transfer Restricted
      Securities pursuant to any Shelf Registration Statement contemplated by
      this Agreement, all to such extent as may be


                                        9



<PAGE>   11



      reasonably requested by the Initial Purchaser or by any Holder of Transfer
      Restricted Securities or underwriter in connection with any sale or resale
      pursuant to any Shelf Registration Statement contemplated by this
      Agreement; and whether or not an underwriting agreement is entered into
      and whether or not the registration is an Underwritten Registration, in
      connection with any Shelf Registration Statement, the Issuers and the
      Guarantors shall:

                (A) furnish to each selling Holder and each underwriter, if any,
           in such substance and scope as they may request and as are
           customarily made by issuers to underwriters in primary underwritten
           offerings, upon the date of the effectiveness of the Shelf
           Registration Statement:

                    (1) a certificate, dated the date of effectiveness of the
                Shelf Registration Statement, signed by (x) the President or any
                Vice President and (y) a principal financial or accounting
                officer of each of the Issuers and the Guarantors, confirming,
                as of the date thereof, the matters set forth in paragraphs (a),
                (b), (c) and (d) of Section 8 of the Purchase Agreement and such
                other matters as such parties may reasonably request;

                    (2) an opinion, dated the date of effectiveness of the Shelf
                Registration Statement, of counsel for the Issuers and the
                Guarantors, covering the matters set forth in the opinion
                rendedered pursuant to paragraph (f) of Section 8 of the
                Purchase Agreement, as applicable, and such other matters as
                such parties may reasonably request, and in any event including
                a statement to the effect that such counsel has participated in
                conferences with officers and other representatives of the
                Issuers and the Guarantors, representatives of the independent
                public accountants for the Issuers, the Initial Purchaser's
                representatives and the Initial Purchaser's counsel in
                connection with the preparation of such Shelf Registration
                Statement and the related Prospectus and have considered the
                matters required to be stated therein and the statements
                contained therein, although such counsel has not independently
                verified the accuracy, completeness or fairness of such
                statements; and that such counsel advises that, on the basis of
                the foregoing (relying as to materiality to the extent such
                counsel deems appropriate upon facts provided to such counsel by
                officers and other representatives of the Issuers and the
                Guarantors and without independent check or verification), no
                facts came to such counsel's attention that caused such counsel
                to believe that the applicable Shelf Registration Statement, at
                the time such Shelf Registration Statement or any post-effective
                amendment thereto became effective, contained an untrue
                statement of a material fact or omitted to state a material fact
                required to be stated therein or necessary to make the
                statements therein not misleading, or that the Prospectus
                contained in such Shelf Registration Statement as of its date
                contained an untrue statement of a material fact or omitted to
                state a material fact necessary in order to make the statements
                therein, in light of the circumstances under which they were
                made, not misleading. Without limiting the foregoing, such
                counsel may state further that such counsel assumes no
                responsibility for, and has not independently verified, the
                accuracy, completeness or fairness of the financial statements,
                notes and schedules and other financial data included in any
                Shelf Registration Statement contemplated by this Agreement or
                the related Prospectus; and

                    (3) a customary comfort letter, dated as of the date of
                effectiveness of the Shelf Registration Statement, from the
                Issuers' independent accountants, in the customary form and
                covering matters of the type customarily covered in comfort
                letters by underwriters in connection with primary underwritten
                offerings, and affirming the matters set forth in


                                       10



<PAGE>   12



                the comfort letters delivered pursuant to Section 8 of the 
                Purchase Agreement, without exception;

                (B) set forth in full or incorporate by reference in the
           underwriting agreement, if any, the indemnification provisions and
           procedures of Section 8 hereof with respect to all parties to be
           indemnified pursuant to said Section; and

                (C) deliver such other documents and certificates as may be
           reasonably requested by such parties to evidence compliance with
           clause (A) above and with any customary conditions contained in the
           underwriting agreement or other agreement entered into by the Issuers
           pursuant to this clause (xi), if any.

           If at any time the representations and warranties of the Issuers and
      the Guarantors contemplated in clause (A)(1) above cease to be true and
      correct, the Issuers or the Guarantors shall so advise the underwriter(s),
      if any, and each selling Holder promptly and, if requested by such
      Persons, shall confirm such advice in writing;

                (xi) prior to any public offering of Transfer Restricted
      Securities, cooperate with the selling Holders, the underwriter(s), if
      any, and their respective counsel in connection with the registration and
      qualification of the Transfer Restricted Securities under the securities
      or Blue Sky laws of such jurisdictions as the selling Holders or
      underwriter(s) may request and do any and all other acts or things
      necessary or advisable to enable the disposition in such jurisdictions of
      the Transfer Restricted Securities covered by the Shelf Registration
      Statement; provided, however, that neither of the Issuers nor any of the
      Guarantors shall be required to register or qualify as a foreign
      corporation where it is not now so qualified or to take any action that
      would subject it to the service of process in suits or to taxation, other
      than as to matters and transactions relating to the Registration
      Statement, in any jurisdiction where it is not now so subject;

                (xii) shall issue, upon the request of any Holder of Series A
      Notes covered by the Shelf Registration Statement, Series B Notes, having
      an aggregate principal amount equal to the aggregate principal amount of
      Series A Notes surrendered to the Issuers by such Holder in exchange
      therefor or being sold by such Holder; such Series B Notes to be
      registered in the name of such Holder or in the name of the purchaser(s)
      of such Notes, as the case may be; in return, the Series A Notes held by
      such Holder shall be surrendered to the Issuers for cancellation;

                (xiii) cooperate with the selling Holders and the
      underwriter(s), if any, to facilitate the timely preparation and delivery
      of certificates representing Transfer Restricted Securities to be sold and
      not bearing any restrictive legends; and enable such Transfer Restricted
      Securities to be in such denominations and registered in such names as the
      Holders or the underwriter(s), if any, may request at least two business
      days prior to any sale of Transfer Restricted Securities made by such
      underwriter(s);

                (xiv) use their reasonable best efforts to cause the Transfer
      Restricted Securities covered by the Registration Statement to be
      registered with or approved by such other governmental agencies or
      authorities as may be necessary to enable the seller or sellers thereof or
      the underwriter(s), if any, to consummate the disposition of such Transfer
      Restricted Securities, subject to the proviso contained in clause (viii)
      above;



                                       11



<PAGE>   13



                (xv) if any fact or event contemplated by clause (c)(iii)(D)
      above shall exist or have occurred, prepare a supplement or post-effective
      amendment to the Registration Statement or related Prospectus or any
      document incorporated therein by reference or file any other required
      document so that, as thereafter delivered to the purchasers of Transfer
      Restricted Securities, the Prospectus will not contain an untrue statement
      of a material fact or omit to state any material fact necessary to make
      the statements therein, in light of the circumstances under which they
      were made, not misleading;

                (xvi) provide a CUSIP number for all Transfer Restricted
      Securities not later than the effective date of the Registration Statement
      and provide the Trustee under the Indenture with printed certificates for
      the Transfer Restricted Securities which are in a form eligible for
      deposit with the Depositary Trust Company;

                (xvii) cooperate and assist in any filings required to be made
      with the NASD and in the performance of any due diligence investigation by
      any underwriter (including any "qualified independent underwriter") that
      is required to be retained in accordance with the rules and regulations of
      the NASD, and use their reasonable best efforts to cause such Registration
      Statement to become effective and approved by such governmental agencies
      or authorities as may be necessary to enable the Holders selling Transfer
      Restricted Securities to consummate the disposition of such Transfer
      Restricted Securities;

                (xviii) otherwise use their best efforts to comply with all
      applicable rules and regulations of the Commission, and make generally
      available to their security holders, as soon as practicable, a
      consolidated earnings statement meeting the requirements of Rule 158
      (which need not be audited) for the twelve-month period (A) commencing at
      the end of any fiscal quarter in which Transfer Restricted Securities are
      sold to underwriters in a firm or best efforts Underwritten Offering or
      (B) if not sold to underwriters in such an offering, beginning with the
      first month of the Company's first fiscal quarter commencing after the
      effective date of the Registration Statement;

                (xix) cause the Indenture to be qualified under the TIA not
      later than the effective date of the first Registration Statement required
      by this Agreement, and, in connection therewith, cooperate with the
      Trustee and the Holders of Notes to effect such changes to the Indenture
      as may be required for such Indenture to be so qualified in accordance
      with the terms of the TIA; and execute and use their best efforts to cause
      the Trustee to execute, all documents that may be required to effect such
      changes and all other forms and documents required to be filed with the
      Commission to enable such Indenture to be so qualified in a timely manner;
      and

                (xx) cause all Transfer Restricted Securities covered by the
      Registration Statement to be listed on each securities exchange on which
      similar securities issued by the Issuers are then listed if requested by
      the Holders of a majority in aggregate principal amount of Series A Notes
      or the managing underwriter(s), if any.

         Each Holder shall be deemed to agree by acquisition of a Transfer
Restricted Security that, upon receipt of any notice from the Issuers of the
existence of any fact of the kind described in Section 6(c)(iii)(D) hereof, such
Holder will forthwith discontinue disposition of Transfer Restricted Securities
pursuant to the applicable Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
6(c)(xvi) hereof, or until it is advised in writing (the "ADVICE") by the
Issuers that the use of the Prospectus may be resumed, and has received copies
of any additional or supplemental filings that are incorporated by reference in
the Prospectus. If


                                       12



<PAGE>   14



so directed by the Issuers, each Holder will deliver to the Issuers (at the
Issuers' expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of such notice. In the event
the Issuers shall give any such notice, the time period regarding the
effectiveness of such Registration Statement set forth in Section 3 or 4 hereof,
as applicable, shall be extended by the number of days during the period from
and including the date of the giving of such notice pursuant to Section
6(c)(iii)(D) hereof to and including the date when each selling Holder covered
by such Registration Statement shall have received the copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof or
shall have received the Advice.


SECTION 7.        REGISTRATION EXPENSES

         (a) All expenses incident to the Issuers' or the Guarantors'
performance of or compliance with this Agreement will be borne by the Issuers
and the Guarantors, regardless of whether a Registration Statement becomes
effective, including without limitation: (i) all registration and filing fees
and expenses (including filings made by the Initial Purchaser or any Holder with
the NASD (and, if applicable, the fees and expenses of any "qualified
independent underwriter" and its counsel that may be required by the rules and
regulations of the NASD)); (ii) all fees and expenses of compliance with federal
securities and state Blue Sky or securities laws; (iii) all expenses of printing
(including printing certificates for the Series B Notes to be issued in the
Exchange Offer and printing of Prospectuses), messenger and delivery services
and telephone; (iv) all fees and disbursements of counsel for the Issuers, the
Guarantors and, subject to Section 7(b) below, the Holders of Transfer
Restricted Securities; (v) all application and filing fees in connection with
listing Notes on a national securities exchange or automated quotation system
pursuant to the requirements hereof; and (vi) all fees and disbursements of
independent certified public accountants of the Issuers and the Guarantors
(including the expenses of any special audit and comfort letters required by or
incident to such performance).

         The Issuers and the Guarantors will, in any event, bear their internal
expenses (including, without limitation, all salaries and expenses of their
officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any Person, including special
experts, retained by the Issuers.

         (b) In connection with any Shelf Registration Statement required by
this Agreement, the Issuers and the Guarantors will reimburse the Holders of
Transfer Restricted Securities being registered pursuant to the Shelf
Registration Statement, as applicable, for the reasonable fees and disbursements
of not more than one counsel, who shall be Latham & Watkins or such other
counsel as may be chosen by the Holders of a majority in aggregate principal
amount of the Transfer Restricted Securities for whose benefit such Shelf
Registration Statement is being prepared.


SECTION 8.        INDEMNIFICATION

         (a) The Issuers and the Guarantors, jointly and severally, agree to
indemnify and hold harmless (i) each Holder, (ii) each person, if any, who
controls any Holder within the meaning of Section 15 of the Act or Section 20(a)
of the Exchange Act and (iii) the respective officers, directors, partners,
employees, representatives and agents of each Holder or any controlling person
to the fullest extent lawful, from and against any and all losses, liabilities,
claims, damages and expenses whatsoever


                                       13



<PAGE>   15



(including but not limited to reasonable attorneys' fees and any and all
expenses whatsoever incurred in investigating, preparing or defending against
any investigation or litigation, commenced or threatened, or any claim
whatsoever, and any and all amounts paid in settlement of any claim or
litigation), joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or otherwise, insofar as such losses,
liabilities, claims, damages or expenses (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
that the Issuers will not be liable in any such case to the extent, but only to
the extent, that any such loss, liability, claim, damage or expense arises out
of or is based upon any such untrue statement or alleged untrue statement or
omission or alleged omission made therein in reliance upon and in conformity
with information relating to any Holder furnished to the Issuers in writing by
or on behalf of such Holder expressly for use therein. This indemnity agreement
will be in addition to any liability which the Issuers and the Guarantors may
otherwise have, including, under this Agreement.

         (b) Each Holder by its participation in the Shelf Registration
Statement shall be deemed to acknowledge and agree, severally and not jointly,
to indemnify and hold harmless the Issuers and the Guarantors and each person,
if any, who controls the Issuers and the Guarantors within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act and the respective
officers, directors, trustees, partners, employees, representatives and agents
of any of them, against any losses, liabilities, claims, damages and expenses
whatsoever (including but not limited to reasonable attorneys' fees and any and
all expenses whatsoever incurred in investigating, preparing or defending
against any investigation or litigation, commenced or threatened, or any claim
whatsoever and any and all amounts paid in settlement of any claim or
litigation), joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or otherwise, insofar as such losses,
liabilities, claims, damages or expenses (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, in each case to the
extent, but only to the extent, that any such loss, liability, claim, damage or
expense arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with information relating to any Holder furnished to the Issuers in
writing by or on behalf of such Holder expressly for use therein; provided,
however, that in no case shall any Holder be liable or responsible for any
amount in excess of the dollar amount of the proceeds received by such Holder
upon the sale of the Notes giving rise to such indemnification obligation. This
indemnity will be in addition to any liability which any Holder may otherwise
have, including under this Agreement.

         (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify each party against whom indemnification is
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 8 except to the extent that it has been prejudiced
in any material respect by such failure or from any liability which it may
otherwise have). In case any such action is brought against any indemnified
party, and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate


                                       14



<PAGE>   16



therein, and to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party. Notwithstanding the foregoing, the
indemnified party or parties shall have the right to employ its or their own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of such indemnified party or parties unless (i) the employment of
such counsel shall have been authorized in writing by the indemnifying parties
in connection with the defense of such action, (ii) the indemnifying parties
shall not have employed counsel to take charge of the defense of such action
within a reasonable time after notice of commencement of the action, or (iii)
such indemnified party or parties shall have reasonably concluded, based upon
the advice of counsel, that there may be defenses available to it or them which
are different from or additional to those available to one or all of the
indemnifying parties (in which case the indemnifying party or parties shall not
have the right to direct the defense of such action on behalf of the indemnified
party or parties), in any of which events such fees and expenses of counsel
shall be borne by the indemnifying parties; provided, however, that the
indemnifying party under subsection (a) or (b) above shall only be liable for
the legal expenses of one counsel (in addition to any local counsel) for all
indemnified parties in each jurisdiction in which any claim or action is
brought. Anything in this subsection to the contrary notwithstanding, an
indemnifying party shall not be liable for any settlement of any claim or action
effected without its prior written consent; provided, however, that such consent
was not unreasonably withheld.

         (d) In order to provide for contribution in circumstances in which the
indemnification provided for in this Section 8 is for any reason held to be
unavailable from the Issuers and the Guarantors or is insufficient to hold
harmless a party indemnified hereunder, the Issuers and the Guarantors, on the
one hand, and each Holder (who shall be deemed to agree to these terms by its
participation in the Exchange Offer or the Shelf Registration Statement), on the
other hand, shall contribute to the aggregate losses, claims, damages,
liabilities and expenses of the nature contemplated by such indemnification
provision (including any investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claims asserted, but after deducting in the case of losses,
claims, damages, liabilities and expenses suffered by the Issuers and the
Guarantors, any contribution received by the Issuers and the Guarantors from
persons, other than the Holders, who may also be liable for contribution,
including persons who control the Issuers and the Guarantors within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act) to which the
Issuers, the Guarantors and such Holder may be subject, in such proportion as is
appropriate to reflect the relative benefits received by the Issuers and the
Guarantors, on one hand, and such Holder, on the other hand, if such allocation
is not permitted by applicable law or indemnification is not available as a
result of the indemnifying party not having received notice as provided in this
Section 8, in such proportion as is appropriate to reflect not only the relative
benefits referred to above but also the relative fault of the Issuers and the
Guarantors, on the one hand, and such Holder, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Issuers and the Guarantors, on one hand,
and each Holder, on the other hand, shall be deemed to be in the same proportion
as (i) the total proceeds from the offering of the Notes (net of discounts but
before deducting expenses) received by the Issuers and the Guarantors and (ii)
the total proceeds received by such Holder upon the sale of the Notes giving
rise to such indemnification obligation. The relative fault of the Issuers and
the Guarantors, on the one hand, and of each Holder, on the other hand, 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 Issuers, the Guarantors
or such Holder and the parties' relative intent, knowledge, access to
information and


                                       15



<PAGE>   17



opportunity to correct or prevent such statement or omission. The Issuers and
the Guarantors agree and the Holders shall be deemed to agree by their
participation in the Exchange Offer or the Shelf Registration Statement that it
would not be just and equitable if contribution pursuant to this Section 8(d)
were determined by pro rata allocation or by any other method of allocation
which does not take into account the equitable considerations referred to above.
Notwithstanding the provisions of this Section 8(d), (i) in no case shall any
Holder be required to contribute any amount in excess of the dollar amount by
which the proceeds received by such Holder upon the sale of the Notes exceeds
the amount of any damages which such Holder has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission and (ii) no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8(d), (A) each person, if any, who controls any Holder within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and (B)
the respective officers, directors, trustees, partners, employees,
representatives and agents of each Holder or any controlling person shall have
the same rights to contribution as such Holder, and each person, if any, who
controls the Issuers and the Guarantors within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act shall have the same rights to
contribution as the Issuers and the Guarantors, subject in each case to clauses
(i) and (ii) of this Section 8(d). Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this Section 8(d), notify such
party or parties from whom contribution may be sought, but the failure to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any obligation it or they may have under this
Section 8(d) or otherwise. No party shall be liable for contribution with
respect to any action or claim settled without its prior written consent;
provided, however, that such written consent was not unreasonably withheld.


SECTION 9.        RULE 144A

         The Issuers and the Guarantors hereby agree with each Holder, for so
long as any Transfer Restricted Securities remain outstanding, to make available
to any Holder or beneficial owner of Transfer Restricted Securities in
connection with any sale thereof and any prospective purchaser of such Transfer
Restricted Securities from such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A.


SECTION 10.       PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

         No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all reasonable questionnaires, powers of attorney, custody
agreements, indemnities, underwriting agreements, lock-up letters and other
documents required under the terms of such underwriting arrangements.

<PAGE>   18



SECTION 11.       SELECTION OF UNDERWRITERS

         The Holders of Transfer Restricted Securities covered by a Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
reasonably satisfactory to the Issuers.


SECTION 12.       MISCELLANEOUS

         (a) REMEDIES. The Issuers and the Guarantors agree that monetary
damages (including the liquidated damages contemplated hereby) would not be
adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Agreement and hereby agree to waive the defense in any action
for specific performance that a remedy at law would be adequate.

         (b) NO INCONSISTENT AGREEMENTS. The Issuers and the Guarantors will
not, on or after the date of this Agreement, enter into any agreement with
respect to their respective securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. Neither of the Issuers nor any of the Guarantors has
previously entered into any agreement granting any registration rights with
respect to its securities to any Person. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Issuers' securities under any agreement in
effect on the date hereof.

         (c) ADJUSTMENTS AFFECTING THE NOTES. Neither of the Issuers nor any
Guarantor will take any action, or permit any change to occur, with respect to
the terms of the Notes that would materially and adversely affect the ability of
the Holders to Consummate any Exchange Offer.

         (d) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless the Issuers have obtained the
written consent of Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities. Notwithstanding the foregoing, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders whose securities are being tendered pursuant to the Exchange
Offer and that does not affect directly or indirectly the rights of other
Holders whose securities are not being tendered pursuant to such Exchange Offer
may be given by the Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities being tendered or registered.

         (e) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

courier guaranteeing overnight delivery:

contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of

        RE:   REGISTRATION STATEMENT ON FORM S-4

Gentlemen:

        This opinion is rendered to you in connection with the preparation of
the registration statement (the "Registration Statement") on Form S-4 under the
Securities Act of 1933, as amended (the "Act"), with respect to the offering by
UNICCO Service Company, a Massachusetts business trust (the "Company") and
UNICCO Finance Corp., a Delaware corporation ("U-Finance"), of up to
$105,000,000 aggregate principal amount of their 9-7/8% Senior Subordinated
Notes, Series B due 2007 (the "Notes") and the related guarantees of the Notes
(the "Guarantees") by certain subsidiaries of the Company (the "Subsidiary
Guarantors"). The Notes and the Guarantees will be issued under an indenture
(the "Indenture") entered into among the Company, the Subsidiary Guarantors and
State Street Bank and Trust Company, as Trustee, in exchange for the Company's
and U-Finance's 9-7/8% Senior Subordinated Notes due 2007 pursuant to the
exchange offer set forth in the Registration Statement (the "Exchange Offer").

        We have acted as counsel to the Company and the Subsidiary Guarantors in
connection with the preparation of the Registration Statement and the proposed
issuance and sale of the Notes. For purposes of this opinion we have reviewed
the Company's Declaration of Trust and By-laws and the charter documents and
By-laws of U-Finance and each of the Subsidiary Guarantors, each as amended to
date. We have also examined such records of corporate proceedings of the
Company, U-Finance and the Subsidiary Guarantors and such other documents as we
have deemed necessary to enable us to render this opinion.

        In rendering this opinion, we have assumed that (i) the Board of
Directors of each of the Subsidiary Guarantors has determined that the
Guarantees are necessary or convenient to the conduct, promotion or attainment
of the business of the Subsidiary Guarantors, and (ii) at the time the
Subsidiary Guarantors incur the Guarantees, none of the Subsidiary Guarantors
(a)(1) will be insolvent or rendered insolvent by reason of such incurrence,
(2) will be engaged in a business or transaction for which the assets remaining
with any such Subsidiary Guarantor constitute unreasonably small capital or
(3) intends to incur, or believes that it will incur, debts beyond its ability
to pay such debts as they mature, and (b) will receive less than reasonably
equivalent value or fair consideration.

        We are attorneys admitted to practice in the Commonwealth of
Massachusetts. We express no opinion concerning the laws of any jurisdiction
other than the laws of the United States of America and the Commonwealth of
Massachusetts and the General Corporation Law of the State of Delaware.

        Based upon and subject to the foregoing, and having regard for such
legal considerations as we have deemed relevant, it is our opinion that the
Notes and the Guarantees have been duly authorized for issuance by all necessary
corporate action on the part of the Company, U-Finance and the Subsidiary
Guarantors and, upon execution and authentication of the Notes as provided in
the Indenture and issuance of the Notes in accordance with the terms of the
Exchange Offer (subject to the effectiveness of the Registration Statement), the
Notes will be the legal, valid and binding obligations of the Company and
U-Finance and the Guarantees will be the legal, valid and binding obligations of
the Subsidiary Guarantors, in each case entitled to the benefits of the
Indenture, except that (i) enforcement of the rights and remedies created
thereby may be limited by bankruptcy, insolvency, reorganization, fraudulent
conveyance or similar laws affecting creditors' rights generally and by
equitable principles which may limit the right to obtain the remedy of specific
performance or other injunctive relief and (ii) we express no opinion as to the
legality, validity or binding nature of any choice of law provision.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our name under the caption "Legal
Matters" in the prospectus contained in the Registration Statement.


                                        Very truly yours,

<PAGE>   29

amounts as requested by the Borrowers up to a maximum aggregate principal amount
outstanding (after giving effect to all amounts requested) at any one time equal
to such Bank's Revolving Credit Commitment; PROVIDED, HOWEVER, that the maximum
aggregate principal amount of all Revolving Loans outstanding (after giving
effect to the amounts requested), plus the aggregate Stated Amount of Letters of

        (a) THE REVOLVING CREDIT NOTES. The Revolving Loans shall be evidenced
by separate Amended and Restated Revolving Credit Notes of the Borrowers to each
Bank in or substantially in the form of EXHIBIT A hereto (collectively, the
"Revolving Credit Notes"), with appropriate insertions.

        (b) NOTE SCHEDULES. The Administrative Agent and the Banks shall, and
are hereby irrevocably authorized by the Borrowers to, enter on the schedule
forming a part of its respective Note or otherwise in its records, appropriate
notations evidencing the date and the amount of each Loan, as applicable, the
interest rate applicable thereto and the date and amount of each payment of
principal made by the Borrowers with respect thereto; and in the absence of
manifest error, such notations shall constitute conclusive evidence thereof. The





                                      -24-


<PAGE>   30

Administrative Agent and each Bank is hereby irrevocably authorized by the
Borrowers to attach to and make a part of its respective Note a continuation of
any such schedule as and when required. No failure on the part of the
Administrative Agent or any Bank to make any notation as provided in this
subsection (b) shall in any way affect any Loan or the rights or obligations of
the Banks or the Borrowers with respect thereto.

        2.3. CONVERSION. Provided that no Default or Event of Default shall have
occurred be continuing, and subject to and in accordance with the provisions of
Section 2.4(a), the Borrowers may convert all or any part (in integral multiples
of $100,000) of any outstanding Loan into a Loan of the other type provided for
in this Agreement in the same aggregate principal amount, on any Business Day
(which, in the case of a conversion of a Eurodollar Loan, shall be the last day
of the Interest Period applicable to such Eurodollar Loan). The Borrowers shall
give the Administrative Agent prior notice of each such conversion (which notice
shall be effective upon receipt) in accordance with Section 2.4. All such
conversions shall be made PRO RATA in accordance with each Bank's Commitment
Percentage.

        2.4. NOTICE AND MANNER OF BORROWING OR CONVERSION OF LOANS.

        (a) Whenever the Borrowers desire to obtain or continue a Loan hereunder
or convert an outstanding Loan into a Loan of the other type provided for in
this Agreement, the Borrowers shall notify the Administrative Agent (which
notice shall be irrevocable) by telecopy and telephone received no later than
12:00 p.m. (Boston time) on the day on which the requested Loan is to be made or
continued as or converted to a Base Rate Loan, and received no later than 12:00
p.m. (Boston time) on the date three Business Days before the day on which the
requested Loan is to be made or continued as or converted to a Eurodollar Loan,
PROVIDED that no more than five Eurodollar Loans may be outstanding at any one
time. Such notice by the Borrowers shall specify (i) the effective date and
amount of each Loan to be obtained, continued or converted (or portion thereof
to be continued or converted, as the case may be), subject to the limitations
set forth in Section 2.1, (ii) the interest rate option to be applicable
thereto, and (iii) the duration of the applicable Interest Period, if any
(subject to the provisions of the definition of Interest Period and Section
2.9). Each Eurodollar Loan must be for an amount equal to at least $500,000 or
an integral multiple thereof. Each such telephonic notification shall be
immediately followed by a written confirmation thereof by the Borrowers in
substantially the form of EXHIBIT B hereto (a "Notice of Borrowing or
Conversion"), PROVIDED that if such written confirmation differs in any material
respect from the action taken by the Administrative Agent, the records of the
Administrative Agent shall be conclusive absent manifest error. The
Administrative Agent agrees that upon receipt of any such telephonic or written
notice of borrowing, it shall notify the other Banks thereof with reasonable
promptness.

        (b) Subject to the terms and conditions hereof, each Bank shall make
available to the Administrative Agent, in immediately available funds, no later
than 2:00 p.m. (Boston time) on the date upon which any Base Rate Loan or
Eurodollar Loan is to be made, such Bank's Commitment Percentage of the
requested Loan. The Administrative 



                                      -25-


<PAGE>   31

Agent shall, in turn, make each Loan on the effective date specified therefor by
crediting the amount of such Loan to the Borrowers' demand deposit account with
the Administrative Agent. In no event shall the BankBoston (in its capacity as
Administrative Agent) have any obligation to make any funding or shall any Bank
be obligated to fund more than its applicable Commitment Percentage of the
requested Base Rate Loan or Eurodollar Loan.

        2.5. COMMITMENT FEE. The Borrowers shall pay to the Administrative
Agent, for the accounts of the Banks in accordance with their respective
Revolving Credit Commitment Percentages, from the Closing Date through the
Revolving Credit Maturity Date, a commitment fee on the average daily amount of
the unborrowed portion of the Revolving Credit Commitments during each fiscal
quarter or portion thereof. Such commitment fee shall be computed by multiplying
such unborrowed portion of the Revolving Credit Commitments in each fiscal
quarter by the rate per annum determined for each quarter by reference to Table
1 below, based upon the Funded Debt Ratio on the last day of the immediately
preceding fiscal quarter:

                                     TABLE 1


                   Funded Debt Ratio at the end of the          Commitment Fee
                   -----------------------------------          --------------
                      immediately preceding quarter
                      -----------------------------

                a)  greater than or equal to 4.00 to 1               .50%

                b)  less than 4.00 to 1 but greater than            .375%
                    or equal to 3.00 to 1

                c)  less than 3.00 to 1                              .25%

Commitment fees shall be payable quarterly in arrears, on the last day of March,
June, September and December of each year beginning December 31, 1997, and on
the Revolving Credit Maturity Date. From the Closing Date through the date after
the day on which the quarterly financial statements are delivered to the Agent,
the Commitment Fee shall equal .50%. Without prejudice to the rights of the
Banks and the Agent under Section 7 or otherwise, if the Borrowers have failed
to deliver the financial statements when required to be delivered by them
pursuant to Section 5.1(a) or Section 5.1(b), and such financial statements,
when delivered, evidence that the Commitment Fee (x) should have been increased
for the applicable quarter, any such increase shall be implemented retroactively
from the date on which such financial statements were required to be delivered,
or (y) should have been decreased, any such decrease shall be effective only
from the date on which such financial statements are actually received by the
Agent. The Borrowers shall notify the Agent in writing of any change in the
Commitment Fee when they submit the financial statements upon which such change
in the Commitment Fee is based, but the 




                                      -26-


<PAGE>   32

failure of the Borrowers to give such notification shall not affect the right of
any party to an adjustment (if applicable).

        2.6. [Intentionally Omitted.]

        2.7. ADMINISTRATIVE AGENT'S FEES. The Borrowers shall pay to the
Administrative Agent, for its own account, the fees (the "Administrative Agent's
Fees") in the amounts and at the times outlined in the agent's fee letter.

        2.8. REDUCTION OF REVOLVING CREDIT COMMITMENT. The Borrowers may from
time to time by written notice delivered to the Administrative Agent at least
three Business Days prior to the date of the requested reduction, reduce by
integral multiples of $100,000 any unborrowed portion of the aggregate Revolving
Credit Commitments. Any such reduction shall be PRO RATA based on the Revolving
Credit Commitment Percentage of each of the Banks. No reduction of the Revolving
Credit Commitments shall be subject to reinstatement.

        2.9. DURATION OF INTEREST PERIODS.

        (a) Subject to the provisions of the definition of Interest Period, the
duration of each Interest Period applicable to a Eurodollar Loan shall be as
specified in the applicable Notice of Borrowing or Conversion. The Borrowers
shall have the option to elect a subsequent Interest Period to be applicable to
such Loan by giving notice of such election to the Administrative Agent received
no later than 10:00 a.m. Boston time on the date three Business Days before the
end of the then applicable Interest Period if such Loan is to be continued as or
converted to a Eurodollar Loan.

        (b) If the Administrative Agent does not receive a notice of election of
duration of an Interest Period for a Eurodollar Loan pursuant to subsection (a)
above within the applicable time limits specified therein, or if, when such
notice must be given, a Default or Event of Default exists, the Borrowers shall
be deemed to have elected to convert such Loan in whole into a Base Rate Loan on
the last day of the then current Interest Period with respect thereto.

        (c) Notwithstanding the foregoing, the Borrower may not select an
Interest Period that would end, but for the provisions of the definition of
Interest Period, after the Revolving Credit Maturity Date.

        2.10. INTEREST RATES AND PAYMENTS OF INTEREST.

        (a) Each Revolving Loan which is a Base Rate Loan shall bear interest on
the outstanding principal amount thereof at a rate per annum equal to the Base
Rate plus the Applicable Base Rate Margin, which rate shall change
contemporaneously with any change in the Base Rate. Such interest shall be
payable quarterly in arrears on the first day of each succeeding quarter in
which a Base Rate Loan is outstanding hereunder, beginning 



                                      -27-


<PAGE>   33

January 1, 1998, and when such Loan is due (whether at maturity, by reason of
acceleration or otherwise).

        (b) Each Revolving Loan which is a Eurodollar Loan shall bear interest
on the outstanding principal amount thereof, for each Interest Period applicable
thereto, at a rate per annum equal to the Adjusted Eurodollar Rate plus the
Applicable Eurodollar Margin. Such interest shall be payable for such Interest
Period on the last day thereof and when such Eurodollar Loan is due (whether at
maturity, by reason of acceleration or otherwise) and, if such Interest Period
is longer than 3 months, at intervals of 3 months after the first day thereof.

        (c) For purposes of this Section 2.10, (i) the "Applicable Base Rate
Margin" shall be equal to (A) from the Closing Date through the day after the
date on which the quarterly financial statements required to be delivered
pursuant to Section 5.1(b) for the quarter ending September 30, 1997 (the
"September 30 Financial Statements") are delivered to the Agent, a percentage
equal to 0.50%, and (B) thereafter, the percentage determined for each Rate
Period by reference to Table 2 below, and (ii) the "Applicable Eurodollar
Margin" shall be (A) from the Closing Date through the day after which the
September 30 Financial Statements are required to be delivered are delivered to
the Agent, a percentage equal to 2.00%, and (B) thereafter, the percentage
determined for each Rate Period by reference to Table 2 below:

           or equal to 4.50 to 1

      c)   less than 4.50 to 1 but greater than        0.50%          2.00%

      d)   less than 4.00 to 1 but greater than        0.25%          1.75%
           or equal to 3.50 to 1

      e)   less than 3.50 to 1 but greater than        0.00%          1.50%
           or equal to 3.00 to 1

For purposes of determining the Applicable Base Rate Margin and the Applicable
Eurodollar Margin, the Funded Debt Ratio will be tested as of the end of each
fiscal quarter of the Borrowers, commencing with the fiscal quarter ending
September 30, 1997, based on the annual or quarterly financial statements
required to be delivered pursuant to Section 5.1(a) or Section 5.1(b),
respectively. For purposes of determining the interest rate for any Rate Period
hereunder, any interest rate change shall be effective on the date after the
date on which the financial statements required to be delivered pursuant to
Section 5.1(a) or Section 5.1(b) are delivered to the Agent. Without prejudice
to the rights of the Banks and the Agent under Section 7 or otherwise, if the
Borrowers have failed to deliver the financial statements when required to be
delivered by them pursuant to Section 5.1(a) or Section 5.1(b), and such
financial statements, when delivered, evidence that the Applicable Base Rate
Margin and the Applicable Eurodollar Margin (x) should have been increased for
the applicable Rate Period, any such increase shall be implemented retroactively
from the date on which such financial statements were required to be delivered,
or (y) should have been decreased, any such decrease shall be effective only
from the date on which such financial statements are actually received by the
Agent. The Borrowers shall notify the Agent in writing of any change in the
Applicable Base Rate Margin and the Applicable Eurodollar Margin when they
submit the financial statements upon which such change in the Applicable Base
Rate Margin and the Applicable Eurodollar Margin is based, but the failure of
the Borrowers to give such notification shall not affect the right of any party
to an adjustment (if applicable).

        2.11. CHANGED CIRCUMSTANCES.

        (a)    In the event that:

        (i)    on any date on which the Adjusted Eurodollar Rate would otherwise
               be set the Administrative Agent shall have determined in good
               faith (which determination shall be final and conclusive) that
               adequate and fair means do not exist for ascertaining the
               Interbank Offered Rate, or

        (ii)   at any time the Administrative Agent (or, in the case of
               subclause (ii) below, any Bank) shall have determined in good
               faith (which determination shall be final and conclusive) that:

               (A)     the making or continuation of, or conversion of any Loan
                       to, a Eurodollar Loan has been made impracticable or
                       unlawful by (l) the occurrence of a contingency that
                       materially and adversely affects the Interbank Eurodollar
                       market or (2) compliance by the Agent or any Bank in good
                       faith with any applicable law or governmental regulation,
                       guideline or order or interpretation or change thereof by
                       any governmental authority charged with the
                       interpretation or administration thereof or with any
                       request or directive of any such governmental authority
                       (whether or not having the force of law); or

               (B)     the Adjusted Eurodollar Rate shall no longer represent
                       the effective cost to the Administrative Agent or any
                       Bank for United States dollar deposits in the interbank
                       Eurodollar market;

then, and in any such event, the Administrative Agent shall forthwith so notify
the Borrowers thereof. Until the Administrative Agent notifies the Borrowers
that the circumstances giving rise to such notice no longer apply, the
obligation of each Bank to allow selection by the Borrowers of the type of Loan
affected by the contingencies described in this Section 2.11(a) (herein called
"AFFECTED LOANS") shall be suspended. If at the time the Administrative Agent so
notifies the Borrowers, the Borrowers have previously given the Administrative
Agent a Notice of Borrowing or Conversion with respect to one or more Affected
Loans but such Loans have not yet gone into effect, such notification shall be
deemed to be void and the Borrowers may borrow Loans of a non-affected type by
giving a substitute Notice of Borrowing or Conversion pursuant to Section 2.4.

        Upon such date as shall be specified in such notice (which shall not be
earlier than the date such notice is given) the Borrowers shall, with respect to
the outstanding Affected Loans, prepay the same, together with interest thereon
and any amounts required to be paid pursuant to Section 2.16, and may borrow a
Loan of another type in accordance with Section 2.1 hereof by giving a Notice of
Borrowing or Conversion pursuant to Section 2.4.




                                      -30-

        (b)    In case any law, regulation, treaty or official directive or the
interpretation or application thereof by any court or by any governmental
authority charged with the administration thereof or the compliance with any
guideline or request of any central bank or other governmental authority
(whether or not having the force of law):

        (i)    subjects the Agent, any Bank or any member of the Borrower
               Affiliated Group to any tax (including, without limitation, any
               withholding tax) with respect to payments of principal or
               interest or any other amounts payable hereunder or under any of
               the Security Documents by any member of the Borrower Affiliated
               Group or otherwise with respect to the transactions contemplated
               hereby (except for taxes on the overall net income of the Agent
               or such Bank imposed by the United States of America or any
               political subdivision thereof), or

        (ii)   imposes, modifies or deems applicable any deposit insurance,
               reserve, special deposit or similar requirement against assets
               held by, or deposits in or for the account of, or loans by, the
               Agent or any Bank (other than such requirements as are already
               included in the determination of the Adjusted Eurodollar Rate),
               or

        (iii)  imposes upon the Agent or any Bank any other condition with
               respect to its performance under this Agreement,

and the result of any of the foregoing is to increase the cost to the Agent or
such Bank, reduce the income receivable by the Agent or such Bank or impose any
expense upon the Agent or such Bank with respect to any Loans, the
Administrative Agent shall notify the Borrower thereof. The Borrowers jointly
and severally agree to pay to the Agent or such Bank the amount of such increase
in cost, reduction in income or additional expense as and when such cost,
reduction or expense is incurred or determined, upon presentation by the Agent
or such Bank of a statement in the amount and setting forth the Agent's or such
Bank's calculation thereof, which statement shall be deemed true and correct
absent manifest error.

        2.12. CAPITAL REQUIREMENTS. If after the date hereof the Agent or any
Bank determines that (i) the adoption of or change in any law, rule, regulation
or guideline regarding capital requirements for banks or bank holding companies,
or any change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (ii) compliance by the
Agent or any Bank or its parent bank holding company with any guideline, request
or directive of any such entity regarding capital adequacy (whether or not
having the force of law), has the effect of reducing the return on the Agent's
or such Bank's or such holding company's capital as a consequence of the Agent's
or such Bank's commitment to make Loans hereunder to a level below that which
the Agent or such Bank or such holding company could have achieved but for such
adoption, change or compliance (taking into consideration the Agent's or such
Bank's or such holding company's then existing policies with respect to capital
adequacy and 



                                      -31-



<PAGE>   37

assuming the full utilization of such entity's capital) by any amount deemed by
the Agent or such Bank to be material, then the Administrative Agent shall
notify the Borrowers thereof. The Borrowers agree to pay to the Agent or such
Bank the amount of such reduction of capital as and when such reduction is
determined, upon presentation by the Agent or such Bank of a statement in the
amount and setting forth the Agent's or such Bank's calculation thereof, which
statement shall be deemed true and correct absent manifest error. In determining
such amount, the Agent or such Bank may use any reasonable averaging and
attribution methods.

        2.13. PAYMENTS AND PREPAYMENTS OF THE LOANS.

        (a) The entire principal of the Revolving Credit Notes shall be
absolutely due and payable by the Borrowers to the Banks having Revolving Credit
Commitments on the Revolving Credit Maturity Date. All of the other Indebtedness
evidenced by the Revolving Credit Notes shall, if not sooner paid, also be
absolutely due and payable by the Borrowers to such Banks on the Revolving
Credit Maturity Date.

        (b) Revolving Loans that are Base Rate Loans may be voluntarily prepaid
at any time, without premium or penalty, upon one Business Day's prior written
notice to the Administrative Agent. Subject to the provisions of Section 2.16,
Revolving Loans that are Eurodollar Loans may be voluntarily prepaid at any
time, without premium or penalty, on the last day of any Interest Period
applicable thereto, upon three Business Days' prior written notice to the
Administrative Agent. Any interest accrued on the amounts so prepaid on
Revolving Loans that are Base Rate Loans (if and to the extent that the
Revolving Credit Commitments are reduced simultaneously with such prepayment)
and on Revolving Loans that are Eurodollar Loans, to the date of such payment,
must be paid at the time of any such payment. No prepayment of the Revolving
Loans prior to the Revolving Credit Maturity Date shall affect the Total
Commitment unless so elected by the Borrowers in accordance with the terms
hereof or impair the Borrowers' right to borrow as set forth in Section 2.l.
Partial prepayments of the Revolving Loans (other than as a result of sweeps
made into the Loan Account from any account of any member of the Borrower
Affiliated Group pursuant to the Lockbox Agreement or other Cash Management
Agreement by the Collateral Agent) shall be in an amount equal to $100,000 or an
integral multiple thereof. In the case of any partial payment of the Revolving
Loans, the total amount of such partial payment shall be allocable among the
Revolving Loans, subject to adjustment as provided in Section 8.5, PRO RATA in
accordance with the Revolving Credit Commitment Percentage of each Bank.

        2.14. METHOD OF PAYMENT. All payments and prepayments of principal and
all payments of interest and other amounts shall be made by the Borrowers to the
Administrative Agent, for the respective accounts of the Banks or (as the case
may be) the Agent, at 100 Federal Street, Boston, Massachusetts 02110, in
immediately available funds, on or before 12:00 p.m. (Boston time) on the due
date thereof, free and clear of, and without any deduction or withholding for,
any taxes or other payments. The Borrowers authorize the Agent and each Bank, in
the Agent's or such Bank's sole discretion, to charge to any deposit account
which any member of the Borrower Affiliated Group may maintain with 



                                      -32-



<PAGE>   38

the Agent or such Bank the principal, interest, fees, charges, taxes and
expenses provided for in this Agreement or any other Loan Document or Security
Document, or to advance to the Borrowers and to charge to them as a Revolving
Loan a sum sufficient to pay such principal, interest, fees, charges, taxes and
expenses, with advice thereafter sent to Unicco's chief financial officer in
accordance with the Agent's or such Bank's customary practice.

        2.15. OVERDUE PAYMENTS.

        (a) Overdue principal (whether at maturity, by reason of acceleration or
otherwise) and, to the extent permitted by applicable law, overdue interest and
fees or any other amounts payable hereunder or under any Note shall bear
interest from and including the due date thereof until paid, compounded monthly
and payable on demand, at a rate per annum equal to (i) if such due date occurs
prior to the end of an Interest Period, 2% above the interest rate applicable to
such Loan for such Interest Period until the expiration of such Interest Period,
and thereafter, 2% above the rate then applicable to Base Rate Loans; and (ii)
in all other cases, 2% above the rate then applicable to Base Rate Loans, which
interest shall be payable on demand.

        (b)   If a payment of principal or interest hereunder is not made within
10 days after its due date, the Borrowers will also pay on demand a late payment
charge equal to 2.5% of the amount of such payment. Nothing in the preceding
sentence shall affect the Agent's or any Bank's right to exercise any of its
rights or remedies, including those provided in Section 7.2, if an Event of
Default has occurred and is continuing.

        2.16. PAYMENTS NOT AT END OF INTEREST PERIOD. If the Borrowers for any
reason make any payment of principal with respect to any Eurodollar Loan on any
day other than the last day of an Interest Period applicable to such Eurodollar
Loan, or fail to borrow or continue or convert to a Eurodollar Loan after giving
a Notice of Borrowing or Conversion pursuant to Section 2.4, the Borrowers shall
pay to the Administrative Agent for the respective accounts of the Banks an
amount computed pursuant to the following formula:

                               L = (R - T) X P X D
                                   ---------------
                                         360

The Borrowers shall pay such amount upon presentation by the Administrative
Agent of a statement setting forth the amount and the Administrative Agent's
calculation thereof pursuant hereto, which statement shall be deemed true and
correct absent manifest error.

        2.17. COMPUTATION OF INTEREST AND FEES. Interest and all fees payable
hereunder shall be computed daily on the basis of a year of 360 days and paid
for the actual number of days for which due. If the due date for any payment of
principal is extended by operation of law, interest shall be payable for such
extended time. If any payment required by this Agreement becomes due on a day
that is not a Business Day such payment may be made on the next succeeding
Business Day (subject to clause (i) of the definition of Interest Period), and
such extension shall be included in computing interest in connection with such
payment.

        2.18. LETTERS OF CREDIT. Upon the terms and subject to the conditions of
this Agreement, and in reliance upon the representations, warranties and
covenants of the Borrowers made herein, the Administrative Agent agrees to
issue, under the joint responsibilities of the Banks, to the extent permitted by
law and the Uniform Customs and Practices of the International Chamber of
Commerce governing Letters of Credit (Publication No. 500 or any successor
thereto), one or more Letters of Credit on the application and for the account
of any Borrower, during the period from the date hereof to the Revolving Credit
Maturity Date; PROVIDED that the Stated Amount of Letters of Credit outstanding
at any time, PLUS the aggregate amount of all unreimbursed draws under such
outstanding Letters of Credit, shall not at any time (i) exceed $2,500,000 in
the aggregate or (ii) when added to the aggregate debit balance in the Loan
Account relating to Revolving Loans at such time, exceed the lesser of (x) the
aggregate Revolving Credit Commitments of all the Banks or (y) the Borrowing
Base; and PROVIDED, FURTHER that at the time the Borrowers request the issuance
of a Letter of Credit and after giving effect to the issuance thereof, there has
not occurred and is not continuing a Default or an Event of Default. It is
understood and agreed by the parties hereto that amounts drawn under such
Letters of Credit shall become immediately due and payable by the Borrowers to
the Administrative Agent, for the ratable accounts of the Agent and the Banks,
and shall bear interest at the rate then applicable to Revolving Loans that are
Eurodollar Loans, and, if not paid forthwith, shall, to the extent there is
availability under the Borrowing Base, be added to the Loan Account as Revolving
Loans and shall be immediately due and payable upon the maturity of the
Revolving Credit Notes. The issuance of any such Letter of Credit shall result
in a reduction of availability under the Borrowing Base in accordance with
Section 2.1. In addition, all Letters of Credit shall, unless the Agent and the
Banks otherwise agree in writing, have a stated expiration date not to exceed
one year and shall, in any event, expire not later than the Revolving Credit
Maturity Date.

        In order to evidence such Letters of Credit, the Borrower shall enter
into, with the Agent (including the Administrative Agent) and the Banks, such
agreements and execute such instruments and documents as the Agent (including
the Administrative Agent) and the Banks require, including, but not limited to,
a letter of credit application and agreement.

        2.19. LETTER OF CREDIT FEES. A Letter of Credit fee shall be payable to
the Administrative Agent, for the ratable accounts of the Banks having Revolving
Credit Commitments, on each Letter of Credit issued at a rate per annum equal to
the Applicable Eurodollar Margin then in effect multiplied by the face amount of
such Letter of Credit, PROVIDED that the Applicable Eurodollar Margin referenced
above shall be reduced by 1/2 of 1% on Letters of Credit issued solely as a
guaranty of the performance by any member of the Borrower Affiliated Group under
any contract of service. In addition a Letter of Credit fee will be payable to
the Administrative Agent, for its own account, for each Letter of Credit issued
by such Administrative Agent, equal to 1/8 of 1% of the face amount of such
Letter of Credit, along with such other fees as are customarily charged by the
Administrative Agent on Letters of Credit. All such Letter of Credit Fees shall
be payable quarterly in arrears, on the last day of each quarter in which any
Letter of Credit is outstanding.

performance of each of the Loan Documents and Ancillary Documents to which any

There are no liabilities, contingent or otherwise, not disclosed in any of such
financial statements that involve a material amount.

the aggregate, been materially adverse (both before and after giving effect to
the High Yield Subordinated Debt Transactions).

        (a) Each member of the Borrower Affiliated Group has obtained all

with the terms and conditions of all such permits, licenses and authorizations,
and is also in compliance with all other limitations, restrictions, conditions,
standards, prohibitions, requirements, obligations, schedules and timetables
contained in any applicable Environmental Law or in any regulation, code, plan,

foregoing, the representations made in this clause (b) with respect to
U-Government and U-Security shall be deemed to be made to the best knowledge of
the members of the Borrower Affiliated Group so long as Unicco and USC are fully

Material has been filed by or on behalf of any member of the Borrower Affiliated

of the Borrower Affiliated Group, or to the best knowledge of the Borrower
Affiliated Group, on any of the real property or properties leased or used in
day-to-day operations by any member of the Borrower Affiliated Group, and no
governmental actions have been taken or are in process which could subject any
of such owned properties to such liens or Encumbrances or, to the best knowledge
of the Borrower Affiliated Group, which could subject any of such leased or used
properties to such liens or Encumbrances, or as a result of which any member of
the Borrower Affiliated Group would be required to place any notice or
restriction relating to the presence of Hazardous Materials at any property
owned by it in any deed to such property.

        (e) No member of the Borrower Affiliated Group nor, to the best
knowledge of any member of the Borrower Affiliated Group, any previous owner,
tenant, occupant or user of any property owned, leased or used by any member of
the Borrower Affiliated Group has (i) engaged in or permitted any operations or
activities upon or any use or occupancy of such property, or any portion
thereof, for the purpose of or in any way involving the handling, manufacture,
treatment, storage, use, generation, release, discharge, refining, dumping or

Materials on, under, in or about such property, except to the extent commonly
used in day-to-day operations of such property and in such case only in
compliance with all Environmental Laws, or (ii) transported any Hazardous

counsel for the Agent, that the Subsidiary shall be bound by the terms of this

instruments as a Borrower hereunder and thereunder and shall enter into such
Security Documents as the Agent and the Banks request; and

        (e) U-Finance shall not hold any material assets, become liable for any
material obligations or engage in any significant business, other than to
provide guaranties for certain Indebtedness of Unicco and the other members of
the Borrower Affiliated Group (to the extent such Guarantees are permitted by

        5.3. MAINTENANCE AND INSURANCE. Each member of the Borrower Affiliated
Group shall maintain its properties in good repair, working order and condition
(reasonable wear and tear, and damage caused by fire or other casualty to the
extent fully covered by insurance (after giving effect to any applicable
commercially reasonable deductible), excepted) as required for the normal
conduct of its business (after giving effect to the Purchase Transactions) and
from time to time the members of the Borrower Affiliated Group will make or
cause to be made all needful and proper repairs, renewals, replacements,
additions and improvements thereto so that the business of the Borrower

the members of the Borrower Affiliated Group in the exercise of their reasonable
judgment deem to be adequate. The Collateral Agent shall be named as loss payee
and additional insured and shall be given 30 days' prior written notice of any

discretion, may provide such insurance and charge the cost thereof to the Loan
Account or to the Borrowers' deposit account with the Agent or any Bank. Any
payment not recovered from the Borrowers shall bear interest at the Base Rate
plus the Applicable Base Rate Margin then in effect. Neither the Agent nor any
Bank shall, by the fact of approving, disapproving, accepting, obtaining or
failing to obtain any such insurance, incur liability for the form or legal
sufficiency of insurance contracts, solvency of insurance companies or payment
of lawsuits, and each member of the Borrower Affiliated Group hereby expressly
assumes full responsibility therefor and liability, if any, thereunder. Each
member of the Borrower Affiliated Group shall furnish to the Collateral Agent

cause to be paid all taxes, assessments or governmental charges on or against it

information thereby received, except that disclosure of such information may be
made (i) to the subsidiaries or affiliates of the Agent or any Bank in
connection with their present or prospective business relations with any member
of the Borrower Affiliated Group, (ii) to prospective transferees or purchasers
of an interest in the Loans, (iii) as required by law, regulation, rule or

and complete entries will be made reflecting all of its business and financial
transactions, and such entries will be made in accordance with GAAP (or Canadian
GAAP, as applicable) and applicable law.

        5.8. ENVIRONMENTAL INDEMNIFICATION. Each member of the Borrower
Affiliated Group covenants and agrees that it will indemnify and hold the Agent

environmental matters relating to any real property or properties owned, leased,
occupied or used by any member of the Borrower Affiliated Group.

        5.9. USE OF PROCEEDS. The proceeds of the Revolving Loans will be used

subject to the terms hereof), the Indebtedness owing to Ogden in an aggregate
amount not to exceed $11,000,000 plus accrued interest and the Indebtedness

        5.11. FISCAL YEAR. Each member of the Borrower Affiliated Group shall

equivalent) whether or not waived, or (iii) terminate any Plan in a manner that

hereof, PROVIDED that such agreements or transactions are not otherwise
prohibited by this Agreement or any of the Security Documents; or (ii)

material adverse effect on the business, property, assets, operations or
condition (financial or otherwise) of any member of the Borrower Affiliated
Group, or (ii) any of the charter or other incorporation documents (including

                                  SECTION VIII

                       CONCERNING THE AGENT AND THE BANKS

        8.1 APPOINTMENT AND AUTHORIZATION. Each of the Banks hereby appoints (i)
BankBoston to serve as Agent, Collateral Agent and Administrative Agent under
this Agreement, and irrevocably authorizes the Agent to take such action on such
Bank's behalf under this Agreement and to exercise such powers and to perform
such duties under this Agreement and the other documents and instruments
executed and delivered in connection with the consummation of the transactions
contemplated hereby as are delegated to the Agent by the terms hereof or
thereof, together with all such powers as are reasonably incidental thereto.

        8.2 AGENT AND AFFILIATES. The Agent shall also have the same rights and
powers under this Agreement of a Bank and may exercise or refrain from
exercising the same as though it were not the Agent, and the Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with any member of the Borrower Affiliated Group or any
Affiliate of any member of the Borrower Affiliated Group as if it were not the
Agent hereunder. Except as otherwise provided by the terms of this Agreement,
nothing herein shall prohibit any Bank from accepting deposits from, lending
money to or generally engaging in any kind of business with any member of the



                                      -68-


<PAGE>   74

Borrower Affiliated Group or any Affiliate of any member of the Borrower
Affiliated Group.

        8.3  FUTURE ADVANCES.

        (a) In order more conveniently to administer the Loans, the
Administrative Agent may, unless notified to the contrary by any Bank prior to
the date upon which any Revolving Loan is to be made, assume that such Bank has
made available to the Administrative Agent on such date the amount of such
Bank's share of such Revolving Loan to be made on such date as provided in this
Agreement, and the Administrative Agent may (but it shall not be required to),
in reliance upon such assumption, make available to the Borrowers a
corresponding amount. If any Bank makes available to the Administrative Agent
such amount on a date after the date upon which the Revolving Loan is made, such
Bank shall pay to the Administrative Agent on demand an amount equal to the
product of (i) the average computed for the period referred to in clause (iii)
below, of the weighted average interest rate paid by the Administrative Agent
for federal funds acquired by the Administrative Agent during each day included
in such period, MULTIPLIED BY (ii) the amount of such Bank's share of such
Revolving Loan, MULTIPLIED BY (iii) a fraction, the numerator of which is the
number of days that elapsed from and including such date to the date on which
the amount of such Bank's share of such Revolving Credit Loan shall become
immediately available to the Administrative Agent, and the denominator of which
is 365. A statement of the Administrative Agent submitted to such Bank with
respect to any amounts owing under this paragraph shall be PRIMA FACIE evidence
of the amount due and owing to the Administrative Agent by such Bank.

        (b) The Administrative Agent may at any time, in its sole discretion,
upon notice to any Bank, refuse to make any Revolving Loan to the Borrower on
behalf of such Bank unless such Bank shall have provided to the Administrative
Agent immediately available federal funds equal to such Bank's share of such
Loan in accordance with this Agreement.

        (c) Anything in this Agreement to the contrary notwithstanding, the
obligations to make Loans under the terms of this Agreement shall be the several
and not joint obligation of each of the Banks and any advances made by the
Administrative Agent on behalf of any Bank are strictly for the administrative
convenience of the parties and shall in no way diminish any Bank's liability to
the Administrative Agent to repay the Administrative Agent for such Loans and
advances. If the amount of any Bank's share of any Revolving Loan which the
Administrative Agent has advanced to the Borrower is not made available to the
Administrative Agent by such Bank within 1 Business Day following the date upon
which such Revolving Loan is made, the Administrative Agent shall be entitled to
recover such amount from the Borrower on demand, with interest thereon at the
rate per annum applicable to the Revolving Loans made on such date.

        8.4 DELINQUENT BANK. Notwithstanding anything to the contrary contained
in this Agreement, any Bank that fails to make available to the Administrative
Agent its share of 




                                      -69-


<PAGE>   75

any Revolving Loan when and to the full extent required by the provisions of
this Agreement shall be deemed delinquent (a "Delinquent Bank") and shall be
deemed a Delinquent Bank until such time as such delinquency is satisfied. A
Delinquent Bank shall be deemed to have assigned any and all payments due to it
from the Borrower, whether on account of outstanding Loans, interest, fees or
otherwise, to the remaining non-delinquent Banks for application to, and
reduction of, their respective PRO RATA shares of all outstanding Revolving
Loans. The Delinquent Bank hereby authorizes the Administrative Agent to
distribute such payments to the non-delinquent Banks in proportion to their
respective PRO RATA shares of all outstanding Revolving Loans. A Delinquent Bank
shall be deemed to have satisfied in full a delinquency when and if, as a result
of application of the assigned payments to all outstanding Revolving Loans of
the non-delinquent Banks, the Banks' respective PRO RATA shares of all
outstanding Loans have returned to those in effect immediately prior to such
delinquency and without giving effect to the nonpayment causing such
delinquency.

        8.5 PAYMENTS.

        (a) All payments and prepayments of principal of and interest on
Revolving Loans received by the Administrative Agent shall be paid to each of
the Banks PRO RATA in accordance with their respective interests in such Loans;
and any other payments received by the Administrative Agent hereunder shall be
paid to the Banks or the Agent or both PRO RATA as their respective interests
appear.

        (b) Each of the Banks and the Agent hereby agrees that if it should
receive any amount (whether by voluntary payment, by the exercise of the right
of set-off or banker's lien, by counterclaim or cross action, by the enforcement
of any right hereunder under or otherwise) in respect of principal of, or
interest on, the Loans or any fees which are to be shared among the Banks,
which, as compared to the amounts theretofore received by the other Banks with
respect to such principal, interest or fees, is in excess of such Bank's PRO
RATA share of such principal, interest or fees as provided in this Agreement,
such Bank shall share such excess, less the costs and expenses (including,
reasonable attorneys' fees and disbursements) incurred by such Bank in
connection with such realization, exercise, claim or action, PRO RATA with all
other Banks in proportion to their respective interests therein, and such
sharing shall be deemed a purchase (without recourse) by such sharing party of
participation interests in the Loans or such fees, as the case may be, owed to
the recipients of such shared payments to the extent of such shared payments;
PROVIDED, HOWEVER, that if all or any portion of such excess amount is
thereafter recovered from such Bank, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.

        8.6 ACTION BY AGENT.

        (a) The obligations of the Agent hereunder are only those expressly set
forth herein. The Agent shall have no duty to exercise any right or power or
remedy hereunder or under any other document or instrument executed and
delivered in connection with or 



                                      -70-


<PAGE>   76

as contemplated by this Agreement or to take any affirmative action hereunder or
thereunder.

        (b) The Administrative Agent shall keep all records of the Loans and
payments hereunder, and shall give and receive notices and other communications
to be given or received by the Administrative Agent hereunder on behalf of the
Banks. The Agent shall receive notices and other communications to be given or
received by the Agent hereunder on behalf of the Banks.

        (c) Upon the occurrence of an Event of Default the Agent may, and upon
the direction of the Majority Banks pursuant to Section 7.2 the Agent shall,
exercise the option of the Banks pursuant to Section 7.2 to declare all Loans
and other Obligations immediately due and payable and may take such action as
may appear necessary or desirable to collect the Obligations and enforce the
rights and remedies of the Agent or the Banks.

        8.7 NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
pursuant to Section 5.1(l)(i) or otherwise, it shall notify the Agent thereof.
The Agent hereby agrees that upon receipt of any notice under this Section 8.7,
it shall notify the other Banks of the existence of such Default or Event of
Default.

        8.8 CONSULTATION WITH EXPERTS. The Agent shall be entitled to retain and
consult with legal counsel, independent public accountants and other experts
selected by it and shall not be liable to the Banks for any action taken,
omitted to be taken or suffered in good faith by it in accordance with the
advice of such counsel, accountants or experts. The Agent may employ agents and
attorneys-in-fact and shall not be liable to the Banks for the default or
misconduct of any such agents or attorneys.

        8.9 LIABILITY OF AGENT. The Agent shall exercise the same care to
protect the interests of each Bank as it does to protect its own interests, so
that so long as such Agent exercises such care it shall not be under any
liability to any of the Banks, except for the Agent's gross negligence or
willful misconduct with respect to anything it may do or refrain from doing.
Subject to the immediately preceding sentence, neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
not taken by it in connection herewith in its capacity as Agent. Without
limiting the generality of the foregoing, neither the Agent nor any of its
respective directors, officers, agents or employees shall be responsible for or
have any duty to ascertain, inquire into or verify: (i) any statement, warranty
or representation made in connection with this Agreement, any other Security
Document, or any borrowing hereunder; (ii) the performance or observance of any
of the covenants or agreements of any member of the Borrower Affiliated Group;
(iii) the satisfaction of any condition specified in Sections 3.1 or 3.2, except
receipt of items required to be delivered to the Agent; (iv) the validity,
effectiveness, enforceability or genuineness of this Agreement, the Notes, any
other Loan Document or any other document or instrument executed and delivered
in connection 



                                      -71-

with or as contemplated by this Agreement; (v) the existence, value,
collectibility or adequacy of the Collateral or any part thereof or the
validity, effectiveness, perfection or relative priority of the liens and
security interests of the Banks (through the Collateral Agent) therein; or (vi)
the filing, recording, refiling, continuing or re-recording of any financing
statement or other document or instrument evidencing or relating to the security
interests or liens of the Banks (through the Collateral Agent) in the
Collateral. The Agent shall not incur any liability by acting in reliance upon
any notice, consent, certificate, statement or other writing (which may be a
bank wire, telecopy or similar writing) believed by it to be genuine or to be
signed or sent by the proper party or parties.

        8.10 INDEMNIFICATION. Each Bank agrees to indemnify the Agent (to the
extent the Agent is not reimbursed by the Borrowers), ratably in accordance with
its Commitment Percentage from and against any cost, expense (including
attorneys' fees and disbursements), claim, demand, action, loss or liability
which the Agent may suffer or incur in connection with this Agreement, or any
action taken or omitted by the Agent hereunder or under any Loan Document, or
such the Agent's relationship with the Borrowers hereunder, including, without
limitation, the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers
and duties hereunder and of taking or refraining from taking any action
hereunder, but excluding any costs, expenses or losses directly arising from the
Agent's gross negligence or willful misconduct. No payment by any Bank under
this Section shall in any way relieve the Borrowers of their obligations under
this Agreement with respect to the amounts so paid by any Bank, and the Banks
shall be subrogated to the rights of the Agent, if any, in respect thereto.

        8.11 INDEPENDENT CREDIT DECISION. Each of the Banks represents and
warrants to the Agent that it has, independently and without reliance upon the
Agent or any other Bank and based on the financial statements referred to in
Section 4.7 and such other documents and information as it has deemed
appropriate, made its own independent credit analysis and decision to enter into
this Agreement. Each of the Banks acknowledges that it has not relied upon any
representation by the Agent and that the Agent shall not be responsible for any
statements in or omissions from any documents or information concerning the
Borrowers, this Agreement, the Notes, any other Loan Document or any other
document or instrument executed and delivered in connection with or as
contemplated by this Agreement. Each of the Banks acknowledges that it will,
independently and without reliance upon the Agent or other Bank and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

        8.12 SUCCESSOR AGENT. BankBoston or any successor Agent may resign as
Agent at any time by giving written notice thereof to the Banks and to the
Borrowers. Upon any such resignation, the Banks shall have the right to appoint
a successor Agent, which successor Agent shall be reasonably acceptable to the
Borrowers, PROVIDED that if BankBoston resigns as Agent, no successor Agent
shall have been so appointed by the Banks, and shall have accepted such
appointment, within 30 days after the retiring 



                                      -72-


<PAGE>   78

Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a commercial bank (or
Affiliate thereof) or savings and loan association organized under the laws of
the United States of America or any State thereof or under the laws of another
country which is doing business in the United States of America or any State
thereof and having a combined capital, surplus and undivided profits of at least
$100,000,000 and shall be reasonably acceptable to the Borrowers. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from all further duties and obligations under this
Agreement. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Section 8 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

                                   SECTION IX

        9.1. UNICCO AS AGENT FOR BORROWERS. Each member of the Borrower
Affiliated Group (other than Unicco) hereby appoint Unicco as their agent with
respect to the receiving and giving of any notices, requests, instructions,
reports, schedules, revisions, financial statements or any other written or oral
communications hereunder. The Agent and each Bank is hereby entitled to rely on
any communications given or transmitted by Unicco as if such communication were
given or transmitted by each and every member of the Borrower Affiliated Group;
PROVIDED, HOWEVER, that any communication given or transmitted by any member of
the Borrower Affiliated Group other than Unicco shall be binding with respect to
such member of the Borrower Affiliated Group. Any communication given or
transmitted by either Agent or any Bank to Unicco shall be deemed given and
transmitted to each and every member of the Borrower Affiliated Group.

                                    SECTION X

means of obtaining repayment of the Obligations, any deposits, balances or other
sums (including the proceeds of insurance on Collateral held by the Collateral
Agent in accordance with the Security Agreements) credited by or due from any

and from time to time after the occurrence and during the continuance of an
Event of Default hereunder, without notice to any Borrower or compliance with
any other condition precedent now or hereafter imposed by statute, rule of law,
or otherwise (all of which are hereby expressly waived) be set off,
appropriated, and applied by such Bank against any and all obligations of any
Borrower to the Banks or any of their respective affiliates in such manner as
the head office of such Bank or any of its branch offices in their sole
discretion may determine, and each Borrower hereby grants such Bank a continuing
security interest in such deposits, balances or other sums for the payment and

        10.5. TERM OF AGREEMENT. This Agreement shall continue in force and

        10.6. NO WAIVERS. No failure or delay by the Agent or any Bank in
exercising any right, power or privilege hereunder or under any Note or under

                                      -75-


<PAGE>   81

Notes provided are cumulative and not exclusive of any rights or remedies
otherwise provided by agreement or law.

        10.7. GOVERNING LAW. This Agreement, the Notes and the other Loan
Documents shall be deemed to be contracts made under seal and shall be construed
in accordance with and governed by the laws of the Commonwealth of Massachusetts
(without giving effect to any conflicts of laws provisions contained therein).
Any legal action or proceeding arising out of or relating to this Agreement, any
other Loan Document or any Obligation may be instituted, in the Agent's sole
discretion, in the courts of the Commonwealth of Massachusetts or the United
States of America for the District of Massachusetts, and the Borrowers hereby
irrevocably submit to the jurisdiction of each such court in any such action or
proceeding; PROVIDED, HOWEVER, that the foregoing shall not limit the Agent's
rights to bring any legal action or proceeding in any other appropriate
jurisdiction.

        10.8. AMENDMENTS, WAIVERS, ETC. Except as otherwise expressly provided
in this Agreement or any of the other Security Documents: (i) each of the
Security Documents may be modified, amended or supplemented in any respect
whatever only with the prior written consent or approval of the Majority Banks
and the Borrowers; and (ii) the performance or observance by the Borrowers of
any of their respective covenants, agreements or obligations under any of the

Banks; PROVIDED, HOWEVER, that the following changes shall require the written
consent, agreement or approval of all of the Banks: (A) any change in the amount

Percentage of any of the Banks, except as permitted by Section 10.10; (D) any

and inure to the benefit of the parties hereto and their respective successors
and assigns; PROVIDED that (i) no Borrower may assign or transfer its rights,
duties or obligations hereunder, and (ii) no Bank may assign or transfer its
rights or obligations hereunder to any person except in accordance with the
provisions of Section 10.10

        10.10. SUCCESSORS AND ASSIGNS.

        (i) Any Bank may at any time grant to one or more banks or other
financial institutions (each, a "Participant") participating interests in any of
its Commitments or any or all of its Loans in an amount and on such terms as
such Bank may think fit. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrowers and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrowers and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights




                                      -76-

<PAGE>   82

and obligations under this Agreement. Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrowers hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; PROVIDED,
HOWEVER, that such participation agreement may provide that such Bank will not
agree, without the consent of the Participant, to any modification, amendment or
waiver of this Agreement requiring the consent, agreement or approval of all of
the Banks, as described in Section 10.8. The Borrowers agree that each
Participant shall be entitled to the benefits of Sections 2.11 and 2.12 with
respect to its participating interest. An assignment or other transfer which is
not permitted by paragraph (ii) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this paragraph (i).

        (ii) Any Bank may at any time assign to one or more banks or other
financial institutions (each, an "Assignee") all, or a part of all, of its
rights, interests and obligations under this Agreement and the Notes (or any one
of its Notes) on such terms, as between such Bank and each of its Assignees, as
such Bank may think fit, and such Assignee shall assume such rights, interests
and obligations, pursuant to an instrument executed by such Assignee and such
transferor Bank; PROVIDED, HOWEVER, that (A) prior to assigning any interest to
any Assignee hereunder, such Bank will (x) notify the Borrowers and the Agent in
writing identifying the proposed Assignee and stating the aggregate principal
amount of the proposed interest to be assigned, and (y) receive the prior
written consent of each of the Borrowers and the Agent, which consent may not be
unreasonably withheld by either the Borrowers or the Agent (it being
acknowledged that it will be deemed reasonable to withhold consent to more than
five Banks hereunder at any one time), and (B) no Bank will assign to any
Assignee less than an aggregate amount equal to $5,000,000 of such Bank's
Commitments and interest in the Notes (or, if less, the remaining Commitment of
such Bank). It is understood and agreed that the proviso contained in the
immediately preceding sentence shall not be applicable in the case of, and this
paragraph (ii) shall not restrict, (A) an assignment or other transfer by any
Bank to an Affiliate of such Bank or to any other Bank or (B) a collateral
assignment or other similar transfer to a Federal Reserve Bank. Upon execution
and delivery of such an instrument and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such
transferor Bank and such Assignee, such Assignee shall be a Bank party to this
Agreement and to each of the other Security Documents to which any other Bank is
a party, and shall have all the rights, interests and obligations of a Bank with
the Commitments as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this paragraph
(ii), the transferor Bank, the Administrative Agent and the Borrower shall make
appropriate arrangements so that, if required, new Notes are issued to the
Assignee.

        (iii) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Sections 2.11 and 2.12
than such Bank 



                                      -77


<PAGE>   83

would have been entitled to receive with respect to the rights transferred,
unless such transfer is made with the Borrowers' prior written consent or at a
time when the circumstances giving rise to such greater payment did not exist.

        (iv) Assignments require a fee payable by the Assignor to the
Administrative Agent, solely for the account of the Administrative Agent, in the
amount of $3,000.

        10.11 SYNDICATION OR PARTICIPATION OF THE LOANS. The Agent, in
cooperation with the Borrowers, will manage all aspects of the syndication or
participation of the Loans, including, without limitation, decisions as to the
selection of financial institutions to be approached, when such financial
institutions will be approached and any titles offered to proposed financial
institutions, which financial institutions will participate (so long as such
financial institutions are reasonably acceptable to the Borrowers), the final
allocation of commitments and the final distribution of fees, and the Agent may,
on behalf of the Borrowers, accept commitments from other financial
institutions. If the Agent deems such actions advisable in order to ensure a
successful syndication or participation, the Agent may propose that this
Agreement be amended, modified or supplemented, PROVIDED that the Total
Commitment remains the same, such changes are agreeable to the Majority Banks or
all of the Banks, as applicable, and such changes are not materially adverse to
the Borrowers. The Borrowers agree to cooperate with the syndication or
participation of the Loans (including assignments and participations) and the
Borrowers will provide all information (including the financial statements
required to be delivered pursuant to Section 4.7), reasonably requested by the
Agent in a form reasonably satisfactory to the Agent. The Borrowers will also
make its management and its advisors available at reasonable times to meet with
potential banks in connection with the syndication or assignment of the Loans.
The Agent will require any potential bank or participant who receives such
information provided by the Borrower to keep such information confidential.

        10.12. COUNTERPARTS. This Agreement may be signed in any number of
counterparts with the same effect as if the signatures hereto and thereto were
upon the same instrument.

        10.13. PARTIAL INVALIDITY. The invalidity or unenforceability of any one
or more phrases, clauses or sections of this Agreement shall not affect the
validity or enforceability of the remaining portions of it.

        10.14. CAPTIONS. The captions and headings of the various sections and
subsections of this Agreement are provided for convenience only and shall not be
construed to modify the meaning of such sections or subsections.

        10.15. WAIVER OF JURY TRIAL. EACH MEMBER OF THE BORROWER AFFILIATED
GROUP AGREES THAT NEITHER IT NOR ANY OF ITS ASSIGNEES OR SUCCESSORS SHALL (A)
SEEK A JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM OR ANY OTHER ACTION
BASED UPON, OR ARISING OUT OF, THIS AGREEMENT, ANY RELATED INSTRUMENTS, ANY
COLLATERAL OR THE DEALINGS OR THE 



                                      -78-

<PAGE>   84

RELATIONSHIP BETWEEN EACH MEMBER OF THE BORROWER AFFILIATED GROUP AND ITS
ASSIGNS AND SUCCESSORS AND THE AGENT AND/OR ANY BANK, OR (B) SEEK TO CONSOLIDATE
ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT
BEEN WAIVED. THE PROVISIONS OF THIS PARAGRAPH HAVE BEEN FULLY DISCUSSED BY THE
AGENT, THE BANKS AND EACH MEMBER OF THE BORROWER AFFILIATED GROUP, AND THESE
PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. EACH MEMBER OF THE BORROWER
AFFILIATED GROUP ACKNOWLEDGES THAT NEITHER THE AGENT NOR ANY BANK HAS AGREED
WITH OR REPRESENTED TO IT THAT THE PROVISIONS OF THIS PARAGRAPH WILL NOT BE
FULLY ENFORCED IN ALL INSTANCES.

        10.16. WAIVER OF SPECIAL DAMAGES. EXCEPT AS PROHIBITED BY LAW, EACH
MEMBER OF THE BORROWER AFFILIATED GROUP HEREBY WAIVES ANY RIGHTS WHICH IT MAY
HAVE TO CLAIM OR RECOVER IN ANY LITIGATION WITH RESPECT TO ANY ACTION OR CLAIM
ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THE LOAN DOCUMENTS, INCLUDING
WITHOUT LIMITATION THIS AGREEMENT, THE NOTES AND THE SECURITY DOCUMENTS AND ANY
AMENDMENTS THEREOF, ANY SPECIAL EXEMPLARY OR PUNITIVE DAMAGES. EACH MEMBER OF
THE BORROWER AFFILIATED GROUP (A) CERTIFIES THAT NO BANK, AGENT OR
REPRESENTATIVE, AGENT OR ATTORNEY THEREOF HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT SUCH ENTITY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT, IN ENTERING INTO THIS
AGREEMENT, THE BANKS AND THE AGENT ARE RELYING UPON, AMONG OTHER THINGS, THE
WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 10.16.

        10.17. ENTIRE AGREEMENT. This Agreement, the Notes, the other Security
Documents and the other documents and agreements executed in connection herewith
constitute the final agreement of the parties hereto and supersede any prior
agreement or understanding, written or oral, with respect to the matters
contained herein and therein.

        10.18. BUSINESS TRUST. Unicco is a Massachusetts business trust. A copy
of the Declaration of Trust establishing such trust is on file with the
Secretary of the Commonwealth of Massachusetts. This Agreement is executed on
behalf of such trust by officers of the trust as officers and not individually.
Without waiving any rights the Agent or the Banks may have under applicable law,
the Agent or the Banks acknowledge that the obligations of such trust under or
arising out of this Agreement are binding upon the assets and property of the
trust and not upon any of the trustees, officers or shareholders of such trust
individually, except as specifically set forth in this Agreement as applicable
to them in such capacity.

June 25, 1996



Mr. John P. McGillicuddy
17 Somerset Avenue
Garden City, NY 11530

Dear Mr. McGillicuddy:

        This letter is to confirm the agreement between you ("Employee") and
UNICCO Service Company ("Employer"), concerning your employment to commence
immediately following the closing of UNICCO's purchase of the Ogden Services
Corporation's Facility Service business.

1.      EMPLOYMENT AND DUTIES

        Employer hereby employs Employee as Chief Operating Officer. Employee
        agrees to perform such services consistent with Employee's position as
        shall, from time to time, be assigned to Employee by the Employer and
        which are customary to such office and necessary to the operations of
        the Employer. Employee shall use Employee's best efforts to promote the
        interest of Employer and shall devote Employee's full business time,
        energy and skill to the business and affairs of Employer during the Term
        set forth below; provided, however, Employer agrees that Employee may
        devote whatever time is reasonably required by Ogden Services
        Corporation in the furtherance of the sale of the New York Region on
        behalf of Ogden Services Corporation. Employer agrees that Employee is
        not required to relocate his family to Boston until June, 1997, and that
        Employee will not be required to further relocate outside of the Boston
        area during the balance of the Term.

2.      TERM OF EMPLOYMENT

        The term of Employee's employment hereunder ("Term") shall commence on
        the next business day following Employer's closing of the purchase of
        the OSC business, and shall continue for a period of three years
        thereafter unless terminated earlier as provided in paragraph 4 of this
        agreement.

3.      COMPENSATION

        As compensation for Employee's services hereunder, Employer agrees to
        provide the following compensation and benefits to employee:

        a)     SALARY. Employee shall receive a base annual salary at the rate
               of $325,000 for year one, $350,000 for year two and $375,000 for
               year three.





<PAGE>   2

        b)     FRINGE BENEFITS. During the Term, Employee shall be entitled to
               use of a company car or a car allowance of $700 per month plus
               all gas, maintenance, and oil expenses, car insurance and other
               fringe benefits as are now, or hereafter may be, established by
               Employer for the benefit of the senior executives of Employer
               (collectively "Fringe Benefits") subject, however, to the
               provisions of the various benefit plans and programs in effect
               from time to time; provided, however, that the fringe benefits,
               if revised by Employer, shall not, when viewed as a whole, be of
               lesser value to Employee than what presently exists.

        c)     VACATION. Employee shall be entitled to four weeks of paid
               vacation each year during the Term.

        d)     BONUS. Employee shall be eligible for a bonus according to an
               incentive plan to be implemented by Employer, modeled after the
               Ogden Services Corporation's plan. The plan will run on a
               year-to-year basis from July 1 to the following June 30. The
               measurement to be used will be a pre-debt service operating
               income plan that will be agreed to by Employer and the Employee
               for the fiscal year. Your incentive target for each year during
               the Term will be $150,000. The Company reserves the right to
               modify or change this plan from year to year but will not do so
               without installing a new plan of at least equal potential value
               for on plan performance.

        e)     LONG TERM INCENTIVE PLAN. In the event the Company institutes a
               long term incentive plan, Employee will participate as a senior
               manager. Such a plan is under consideration.

        f)     RELOCATION COSTS. Employer will reimburse Employee (on a net
               after-tax basis) up to $75,000 for out-of-pocket costs and
               expenses associated with selling his present home, moving
               expenses (including packing and storage costs) and closing costs
               associated with purchasing a new home in the Boston area. Such
               costs will include without limitation real estate commissions,
               transfer fees and other costs normally paid by seller, closing
               costs in connection with the new home, bridge loan expenses, and
               points for any loan origination fee in connection with obtaining
               a mortgage for Employee's new home.

        g)     EXPENSES. Except as otherwise herein provided, Employer agrees to
               reimburse Employee's reasonable business expenses, including
               Employee's travel, meal and lodging expenses in and to Boston
               during the first year of the Term.

        h)     STOCK OPTIONS. In the event that Employer should register its
               securities in a public offering during the Term, Employer agrees
               that Employee will be included in any incentive stock option plan
               adopted by Employer.

4.      TERMINATION





                                      -2-
<PAGE>   3



        a)     This Agreement may be terminated on written notice for either of
               the following reasons:

               (i)     The death of the Employee; or 
               (ii)    The physical or mental disability of Employee to such an
                       extent that Employee is unable to render services to
                       Employer for a continuous period exceeding one hundred
                       eighty (180) days.

        b)     In the event that Employer terminates this Agreement due to
               Employee's death or disability, Employee or his estate, as the
               case may be, shall be paid Employee's salary and shall continue
               to receive all accrued Fringe Benefits hereunder through the end
               of the month in which the termination event occurs.

        c)     Employer shall have the right at any time, by written notice to
               Employee to terminate this Agreement immediately for "cause",
               which for purposes of this Agreement shall be defined as:

               (i)     Employee's conviction of any act which constitutes a
                       felony under federal, state or local laws or the law of
                       any foreign country;
               (ii)    Employee's failure or refusal to adequately perform
                       Employee's duties and responsibilities hereunder in
                       accordance with the reasonable directions of the Board of
                       Directors of Employer which failure or refusal is within
                       his reasonable control and is not cured by Employee
                       within thirty (30) days of Employee's receipt of written
                       notice thereof from Employer's Board of Directors;
                       provided, however, that if any such failure or refusal to
                       adequately perform Employee's duties and responsibilities
                       hereunder cannot reasonably be cured within thirty (30)
                       days of Employee's receipt of written notice thereof,
                       Employer may not terminate Employee pursuant to this
                       paragraph 4(c)(ii) if Employee has taken appropriate
                       action to commence the cure of any such breach within a
                       ten (10) day period and completes the cure within a
                       reasonable period of time thereafter.
               (iii)   Employee's dishonesty which materially adversely affects
                       the business of Employer;

               (iv)    Employee's failure to cure any other material breach of
                       this Agreement within thirty (30) days of receipt of a
                       written notice from Employer specifying such breach.

        d)     In the event Employer terminates this Agreement for "cause",
               Employee shall be paid Employee's salary and shall receive all
               Fringe Benefits through the date of termination. Employee shall
               not receive any further payments or benefits hereunder.

        e)     In the event of any dispute relating to whether Employee was
               properly terminated for "cause" by Employer, such dispute shall
               be arbitrated in accordance with the 



                                      -3-

<PAGE>   4

               rules of the American Arbitration Association in Boston,
               Massachusetts, and the losing party shall pay the attorneys fees
               of the winning party to such arbitration.

        f)     Upon termination of this Agreement, Employee shall promptly
               return all of Employer's property to Employer.

        g)     Upon termination of Employee's employment for any reason,
               Employee shall tender Employee's resignation from any Board of
               Directors on which Employee is then serving in connection with
               his services hereunder.

        h)     Employer acknowledges that Employee has executed an Employment
               Agreement with Ogden Services Corporation which extends to May 1,
               2003, and that Ogden Services Corporation has released Employee
               from its contract for the Term of this Agreement. Employer
               further acknowledges that Employee may elect to return to Ogden
               Services Corporation's employ at the end of the Term if a
               mutually satisfactory arrangement has not been reached between
               Employer and Employee. Employer acknowledges that Employee will
               remain on Ogden Services Corporation's payroll during the Term in
               order not to cause a break in service.

5.      CONFIDENTIAL INFORMATION

        a)     Employee will not either during his employment by Employer or
               within two (2) years thereafter disclose, use or make known for
               his or another's benefit, any confidential information,
               knowledge, or data of Employer or any affiliate of Employer.

        b)     Immediately upon the termination of his employment with Employer,
               Employee shall deliver to Employer all copies of data,
               information and knowledge, including, without limitation, all
               documents, blueprints, photographs, correspondence, notebooks,
               reports, computer programs, price lists, customer lists, samples,
               lists of suppliers and craftsmen, designs, names of full-time and
               part-time employees, free-lance workers and consultants, and all
               other materials and copies thereof relating in any way to the
               business of Employer in any way obtained by Employee in
               connection with his employment with Employer.

6.      SURVIVAL

        Employee's duties under paragraph 5 of this Agreement shall survive the
        termination of this Agreement and the termination of Employee's
        employment with Employer. Employee acknowledges that a remedy at law for
        any breach or threatened breach by Employee of the provisions of this
        Agreement may be inadequate, and Employee therefore agrees that Employer
        shall be entitled to injunctive relief in case of any such breach or
        threatened breach.

paragraphs 5 and 6 thereof which shall survive as set forth in paragraph 7
thereof.

      2.    COMPENSATION.

            (a) The Company has simultaneously paid to Trow $25,000 (less tax

      11.   GENERAL.

            (a) Trow and the Company agree that any breach of this Agreement
      could cause irreparable damage and that, in the event of such breach, each
      shall have, in addition to any and all remedies at law, the right to seek
      an injunction, specific performance or other equitable relief to prevent
      the violation of a party's obligations hereunder.

            (b) Each provision herein shall be treated as a separate and
      independent clause, and the unenforceability of any one clause shall in no
      way impair the enforceability of any of the other clauses herein.
      Moreover, if one or more of the provisions contained in this Agreement
      shall for any reason be held to be excessively broad as to scope, activity
      or subject so as to be unenforceable at law, such provision or provisions
      shall be construed by the appropriate judicial body by limiting and
      reducing it or them, so as to be enforceable to the extent compatible with
      the applicable law as it shall then appear.

            (c) No waiver by a party hereto of a breach of any provision of this
      Agreement shall be deemed to be a waiver of any preceding or subsequent
      breach of the same or any other provision thereof.

            (d) This Agreement shall be governed by the laws of Massachusetts.
      This Agreement and the ancillary agreements referred to herein set forth
      the entire agreement between the parties and supersede all prior
      agreements and understandings relating to the subject matter hereof. Any
      amendment or modification hereof will be effective only if in writing and
      signed by the parties affected thereby.

            (e) This Agreement shall bind and benefit the parties hereto and
      their respective successors and assigns.

      12.   This Severance Agreement shall constitute an accord and satisfaction

                            SHARE PURCHASE AGREEMENT
                            (UNICCO Service Company)


        This Share Purchase Agreement (the "Agreement") dated as of June 20,
1996, is between UNICCO Service Company, a Massachusetts business trust
("UNICCO") and George A. Keches (the "Purchaser").

        UNICCO hereby offers to the Purchaser, and the Purchaser hereby
subscribes for, 27 Non-Voting shares (the "Shares") of UNICCO under the terms
and conditions set forth herein.

        Therefore, the Parties agree as follows:

        1. PURCHASE AND SALE. Upon the execution of this Agreement, UNICCO shall
issue and deliver to the Purchaser a certificate representing 27 Shares in
consideration of the Purchaser's payment of $8,035.42 per share (for a total of
$216,945.00) to be paid by delivery of a Promissory Note in the form of EXHIBIT
A hereto.

        2. REPURCHASE OF SHARES. If at any time the Purchaser's employment with
UNICCO is terminated for any reason (including, without limitation, voluntary
termination, involuntary termination by UNICCO with or without cause, or death
or disability), the Purchaser shall be required to sell, and UNICCO shall be
required to purchase, for the purchase price described below, all of the Shares
sold to the purchaser hereunder. The purchase price of the Shares sold pursuant
to this Section 2 shall be the book value of such shares, determined by UNICCO's
independent public accountants (the "Accountants") as of the last day of the
month next preceding the month in which the termination of Purchaser's
employment with UNICCO shall have occurred, which determination shall be final
and binding on all parties hereto in the absence of manifest error.

        Notwithstanding the foregoing provisions, if (a) UNICCO terminates the
Purchaser's employment without cause and (b) UNICCO or Steven C. Kletjian,
Robert P. Kletjian, Richard J. Kletjian, and George A. Keches (the "Existing
Stockholders") enter into an agreement within one year after the effective date
of the Purchaser's termination of employment in which (i) UNICCO agrees to sell
all or substantially all of its assets not in the ordinary course of its
business or (ii) the Existing Stockholders agree to sell more than fifty (50%)
percent of their shares of UNICCO (to persons or entities other than Permitted
Transferees, as defined below), the Purchaser shall be entitled to receive a
percentage of the consideration received by UNICCO from the sale of its assets
after satisfaction of all liabilities or received by the Existing Stockholders
for the sale of their shares, as the case may be, equivalent to the percentage
of the shares of UNICCO previously owned by the Purchaser on the effective date
of such termination as reduced by all previous payments made to the Purchaser
pursuant to this Section.

        "Permitted Transferees" as used herein means (i) other Existing
Stockholders, (ii) the spouses, parents, sisters, brothers, ancestors and lineal
descendants ("Family Members") of Existing Stockholders or any trust established
for the benefit of any Family Members of Existing 





<PAGE>   2

Stockholders, (iii) any corporation, partnership, trust or other entity in which
the Existing Stockholders or Family Members own more than fifty (50%) percent of
the outstanding capital stock, partnership interest or other beneficial interest
or (iv) any estate of a deceased Existing Stockholder or Family Member.

        3. CLOSING OF UNICCO PURCHASE. The closing of any purchase and sale of
Shares required under the provisions of Section 2 shall be held within a
reasonable time, not to exceed sixty (60) days, after the termination of the
Purchaser's employment with UNICCO. At the closing, UNICCO shall make payment
for the Shares being purchased by delivering the full amount of the total
purchase price in cash or by certified or bank check, and the Purchaser (or his
legal representative, in the event of the Purchaser's death) shall deliver to
UNICCO the certificates for the Shares being sold, free and clear of all liens
and encumbrances, together with duly executed stock powers. At the closing, the
Purchaser shall repay UNICCO, in cash or by certified or bank check, the full
principal amount (and all accrued and unpaid interest thereon) of all loans and
advances made by UNICCO to the Purchaser.

        4. RESTRICTIONS ON TRANSFER. The Purchaser agrees that, during the term
of his employment with UNICCO, he will not sell, assign, give, transfer, pledge,
hypothecate, mortgage or otherwise encumber or dispose of all or any of the
Shares (or any interest therein) transferred to him pursuant hereto. UNICCO may
at any time waive any restriction imposed by this Section 4 with respect to all
or any portion of such shares.

        5. TERMINATION OF RESTRICTIONS UPON PUBLIC OFFERING. The restrictions on
transfer set forth in Section 4 hereof, and the obligations set forth in Section
2 hereof, shall terminate upon an offering and distribution (if ever) to the
public of shares of UNICCO's voting shares of Common Stock pursuant to a
registration statement filed under the Securities Act of 1933, as amended (the
"Securities Act"), or a successor statute.

        6. INVESTMENT REPRESENTATION. The Purchaser represents that his
acquisition of the Shares is for his own account for investment and not with a
view to the resale or distribution thereof, and that no subsequent sale or offer
for sale of the Shares shall be made unless (i) the Shares are registered under
the Securities Act and applicable state securities laws or (ii), in the opinion
of UNICCO's counsel, an exemption from such registration is available.

        7. EMPLOYMENT RIGHTS. The Purchaser's ownership of the Shares shall not
confer upon him any right with respect to his employment by UNICCO, UNICCO or
any parent or subsidiary of UNICCO nor shall such ownership interfere in any way
with the right of any of such companies to terminate the employment of the
Purchaser.

        8. LEGEND ON CERTIFICATES. UNICCO shall place a legend on each
certificate representing the Shares transferred to the Purchaser hereunder
reflecting the restrictions on transfer and UNICCO's repurchase obligations set
forth herein.

        9. NOTICES. Any communication or notice required or permitted to be
given under this 





<PAGE>   3

Agreement shall be in writing and mailed by registered or certified mail or
delivered in hand, if to UNICCO and the Existing Stockholders, to UNICCO's
Treasurer at 4 Copley Place, Boston, Massachusetts 02116 or such other address
as UNICCO may specify in writing to the Purchaser, and if to the Purchaser, to
such address as the Purchaser shall last have furnished to UNICCO.

        10. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
heirs, executors, administrators, successors and assigns of the respective
parties hereto.

        Executed as a sealed instrument as of June 20, 1996.

                            SHARE PURCHASE AGREEMENT


        This Share Purchase Agreement ("Agreement") dated as of July 1, 1989, is
between Unicco Service Company, a Massachusetts business trust ("Unicco") and
John C. Feitor (the "Purchaser").

        Unicco hereby offers to the Purchaser, and the Purchaser hereby
subscribes for, 27 shares of Non Voting Beneficial Interest (the "Shares") of
Unicco under the terms and conditions set forth herein.

        Therefore, the parties agree as follows:

        1. PURCHASE AND SALE. Upon the execution of this Agreement, Unicco shall
issue and deliver to the Purchaser a certificate representing 27 Shares in
consideration of the Purchaser's payment of $70,983.00 therefor, payable ten
(10%) percent by certified or bank check and the remainder by issuance and
delivery to Unicco of a Promissory Note in the form of Exhibit A hereto, with
interest at the minimum rate which must be stated to avoid imputed interest for
Federal income tax purposes.

        2. REPURCHASE OF SHARES If at any time the Purchaser's employment with
Unicco is terminated for any reason (including, without limitation, voluntary
termination, involuntary termination by Unicco with or without cause, or death
or disability), the Purchaser shall be required to sell, and Unicco shall be
required to purchase, for the purchase price described below, all of the Shares
sold to the Purchaser hereunder. The purchase price of the Shares shall be the
book value of such shares, determined by Unicco's independent public accountants
as of the last day of the month next preceding the month in which the
termination of Purchaser's employment with Unicco shall have occurred.

        The closing of any purchase and sale of Shares required under the
provisions of this Section 2 shall be held within a reasonable time, not to
exceed sixty (60) days, after the termination of the Purchaser's employment with
Unicco. At the closing, Unicco shall make payment for the Shares being purchased
by delivering the full amount of the total purchase price in cash or by
certified or bank check, and the Purchaser (or his legal representative, in the
event of the Purchaser's death) shall deliver to Unicco the certificates for the
Shares being sold, free and clear of all liens and encumbrances, together with
duly executed stock powers. At the closing, the Purchaser shall repay Unicco, in
cash or by certified or bank check, the full principal amount (and all accrued
and unpaid interest thereon) of all loans and advances made by Unicco to the
Purchaser.

        Notwithstanding the foregoing provisions, if (a) Unicco terminates the
Purchaser's employment without cause and (b) Unicco or Steven C. Kletjian,
Robert P. Kletjian, Richard J. Kletjian and Louis J. Lanzillo (the "Existing
Stockholders") enter into an agreement within one year after the effective date
of the Purchaser's termination of employment in which (i) Unicco agrees to sell
all or substantially all of its assets not in the ordinary course of its
business or (ii) the Existing Stockholders agree to sell more than 50% of their
shares of beneficial interest in Unicco (to persons or entities other than
Permitted Transferees, as defined below), the Purchaser shall be entitled to
receive a percentage of the consideration received by Unicco from the sale of
its assets 





<PAGE>   2

after satisfaction of all corporate liabilities or received by the Existing
Stockholders for the sale of their shares, as the case may be, equivalent to the
percentage of the beneficial interest of Unicco previously owned by the
Purchaser on the effective date of such termination as reduced by all previous
payments made to the Purchaser pursuant to this Section.

        "Permitted Transferees" as used herein means (i) other Existing
Stockholders, (ii) the spouses, parents, sisters, brothers, ancestors and lineal

partnership, trust or other entity in which the Existing Stockholders or Family
Members own more than fifty percent (50%) of the outstanding capital stock,
partnership interest or other beneficial interest or (iv) any estate of a
deceased Existing Stockholder or Family Member.

        3. RESTRICTIONS ON TRANSFER. The Purchaser agrees that, during the term
of his employment with Unicco, he will not, except pursuant to the Pledge and
Escrow Agreement of even date herewith among the Purchaser, Unicco and Noel G.
Posternak, P.C., as Escrow Agent, sell, assign, give, transfer, pledge,
hypothecate, mortgage or otherwise encumber or dispose or dispose of all or any
of the Shares (or any interest therein) transferred to him pursuant hereto.
Unicco may at any time waive any restriction imposed by this Section 3 with
respect to all or any portion of such shares.

        4. TERMINATION OF RESTRICTIONS UPON PUBLIC OFFERING. The restrictions on
transfer set forth in Section 3 hereof, and the obligations imposed by Section 2
hereof, shall terminate upon an offering and distribution (if ever) to the
public of shares of Unicco's voting shares of beneficial interest pursuant to a
registration statement filed under the Securities Act of 1933, as amended (the
"Securities Act"), or a successor statute.

        5. INVESTMENT REPRESENTATION. The Purchaser represents that his
acquisition of the Shares is for his own account for investment and not with a
view to the resale or distribution thereof, and that no subsequent sale or offer
for sale of the Shares shall be made unless (i) the Shares are registered under
the Securities Act and applicable state securities laws or (ii), in the opinion
of Unicco's counsel, an exemption from such registration is available.

        6. EMPLOYMENT RIGHTS. The Purchaser's ownership of the Shares shall not
confer upon him any right with respect to his employment by Unicco or any parent
or subsidiary corporation of Unicco nor shall such ownership interfere in any
way with the right of any of such corporations to terminate the employment of
the Purchaser.

        7. LEGEND ON CERTIFICATES. Unicco shall place a legend on each
certificate representing the Shares transferred to the Purchaser hereunder
reflecting the restrictions on transfer and Unicco's repurchase obligations set

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the principal amount of the Notes
indicated above. Subject to, and effective upon, the acceptance for exchange of
such Notes tendered hereby, the undersigned hereby exchanges, sells, assigns and
transfers to, or upon the order of, the Company all right, title and interest in
and to such Notes as are being tendered hereby, including all rights to accrued
and unpaid interest thereon as of the Expiration Date. The undersigned hereby
irrevocably constitutes and appoints the Exchange Agent as the true and lawful
agent and attorney-in-fact of the undersigned (with full knowledge that said
Exchange Agent acts as the agent of the Company in connection with the Exchange
Offer) to cause the Notes to be assigned, transferred and exchanged. The
undersigned represents and warrants that it has full power and authority to
tender, exchange, sell, assign and transfer the Notes tendered hereby and to
acquire Exchange Notes issuable upon the exchange of such tendered Notes, and
that when the same are accepted for exchange, the Company will acquire good and
unencumbered title to the tendered Notes, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim.

         The undersigned represents to the Company that (i) the Exchange Notes
acquired pursuant to the Exchange Offer are being obtained in the ordinary
course of business of the person receiving such Exchange Notes, whether or not
such person is the undersigned; (ii) neither the undersigned nor any such other
person has an arrangement or understanding with any person to participate in a
distribution of such Exchange Notes; and (iii) the undersigned and any such
other person acknowledge that, if they are participating in the Exchange Offer
for the purpose of distributing the Exchange Notes, (a) they cannot rely on the
position of the staff of the Securities and Exchange Commission enunciated in
Exxon Capital Holdings Corporation (available April 13, 1989), Morgan Stanley &
Co., Inc. (available June 5, 1991) or similar no-action letters and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with the
resale transaction and (b) failure to comply with such requirements in such
instance could result in the undersigned or any such other person incurring
liability under the Securities Act for which such persons are not indemnified by
the Company. If the undersigned or the person receiving the Exchange Notes
covered by this letter is an affiliate (as defined under Rule 405 of the
Securities Act) of the Company, the Exchange Notes may not be offered for
resale, resold or otherwise transferred by the undersigned or such other person
without registration under the Securities Act or an exemption therefrom. If the
exchange offeree is a broker-dealer holding Notes acquired for its own account
as a result of market-making activities or other trading activities, it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of Exchange Notes received in respect of such Notes
pursuant to the Exchange Offer; however, by so acknowledging and by delivering a
prospectus, the undersigned will not be

deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

         The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed by the Exchange Agent or the Company to
be necessary or desirable to complete the exchange, sale, assignment and
transfer of tendered Notes or transfer ownership of such Notes on the account
books maintained by a book-entry transfer facility. The undersigned further
agrees that acceptance of any tendered Notes by the Company and the issuance of
Exchange Notes in exchange therefor shall constitute performance in full by the
Company of its obligations under the Registration Rights Agreement and that the
Company shall have no further obligations or liabilities thereunder for the
registration of the Notes or the Exchange Notes.

         The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offer -- Conditions." The undersigned
recognizes that as a result of these conditions (which may be waived, in whole
or in part, by the Company), as more particularly set forth in the Prospectus,
the Company may not be required to exchange any of the Notes tendered hereby
and, in such event, the Notes not exchanged will be returned to the undersigned
at the address shown below the signature of the undersigned.

         All authority herein conferred or agreed to be conferred shall survive
the death, bankruptcy or incapacity of the undersigned and every obligation of
the undersigned hereunder shall be binding upon the heirs, personal
representatives, successors and assigns of the undersigned. TENDERED NOTES MAY
BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION DATE.

         Unless otherwise indicated in the box entitled "Special Registration
Instructions" or the box entitled "Special Delivery Instructions" in this Letter
of Transmittal, certificates for all Exchange Notes delivered in exchange for
tendered Notes, and any Notes delivered herewith but not exchanged, will be
registered in the name of the undersigned and shall be delivered to the
undersigned at the address shown below the signature of the undersigned. If an
Exchange Note is to be issued to a person other than the person(s) signing this
Letter of Transmittal, or if the Exchange Note is to be mailed to someone other
than the person(s) signing this Letter of Transmittal or to the person(s)
signing this Letter of Transmittal at an address different than the address

Transmittal should be completed. If Notes are surrendered by Holder(s) that have
completed either the box entitled "Special Registration Instructions" or the box
entitled "Special Delivery Instructions" in this Letter of Transmittal,
signature(s) on this Letter of Transmittal must be guaranteed by an Eligible
Institution (as defined in Instruction 2).

                          FORMING PART OF THE TERMS AND
                        CONDITIONS OF THE EXCHANGE OFFER

1.        DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

         All physically delivered Notes or confirmation of any book-entry
transfer to the Exchange Agent's account at a book-entry transfer facility of
Notes tendered by book-entry transfer, as well as a properly completed and duly
executed copy of this Letter of Transmittal or facsimile thereof, and any other
documents required by this Letter of Transmittal, must be received by the
Exchange Agent at any of its addresses set forth herein on or prior to the
Expiration Date. The method of delivery of this Letter of Transmittal, the
tendered Notes and all other required documents is at the election and risk of
the Holder. Instead of delivery by mail, it is recommended that Holders use an
overnight or hand delivery service. Except as otherwise provided below, the
delivery will be deemed made only when actually received by the Exchange Agent.
In all cases, sufficient time should be allowed to assure timely delivery to the
Exchange Agent before the Expiration Date.

         No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering Holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Notes for exchange.


         Delivery to an address other than as set forth herein, or instructions
via a facsimile number other than the ones set forth herein, will not constitute
a valid delivery.

2.       GUARANTEED DELIVERY PROCEDURES.

         Holders who wish to tender their Notes, and (i) whose Notes are not
immediately available, or (ii) who cannot deliver their Notes, the Letter of
Transmittal or any other 

                                       10
<PAGE>   11
required documents to the Exchange Agent (or comply with the procedures for
book-entry transfer) prior to the Expiration Date, may effect a tender if:

         a. the tender is made through a member firm of a registered national
         securities exchange or of the National Association of Securities
         Dealers, Inc., a commercial bank or trust company having an office or
         correspondent in the United States or an "eligible guarantor
         institution" within the meaning of Rule 17Ad-15 under the Exchange Act
         (an "Eligible Institution");

         b. prior to the Expiration Date, the Exchange Agent receives from such
         Eligible Institution a properly completed and duly executed Notice of
         Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
         setting forth the name and address of the Holder of the Notes, the
         certificate or registration number(s) of such Notes and the principal
         amount of Notes tendered, stating that the tender is being made thereby
         and guaranteeing that, within five (5) business days after the
         Expiration Date, the Letter of Transmittal (or facsimile thereof),
         together with the certificate(s) representing the Notes to be tendered
         in proper form for transfer (or a confirmation of book-entry transfer
         of such Notes into the Exchange Agent's account at the Depository) and
         any other documents required by the Letter of Transmittal, will be
         deposited by the Eligible Institution with the Exchange Agent; and

         c. such properly completed and executed Letter of Transmittal (or
         facsimile thereof), as well as all tendered Notes in proper form for
         transfer (or a confirmation of book-entry transfer of such Notes into
         the Exchange Agent's account at the Depository) and all other documents
         required by the Letter of Transmittal, are received by the Exchange
         Agent within five business days after the Expiration Date.

         Upon request to the Exchange Agent, a Notice of Guaranteed Delivery
will be sent to Holders who wish to tender their Notes according to the
guaranteed delivery procedures set forth above. Any Holder who wishes to tender
Notes pursuant to the guaranteed delivery procedures described above must ensure
that the Exchange Agent receives the Notice of Guaranteed Delivery relating to
such Notes prior to the Expiration Date. Failure to complete the guaranteed
delivery procedures outlined above will not, of itself, affect the validity or
effect a revocation of any Letter of Transmittal form properly completed and
executed by a Holder who attempted to use the guaranteed delivery procedures.

3.       PARTIAL TENDERS; WITHDRAWALS.

         If less than the entire principal amount of Notes evidenced by a
submitted certificate is tendered, the tendering Holder should fill in the
principal amount tendered in the column entitled "Principal Amount Tendered" of
the box entitled "Description of Senior 

                                       11
<PAGE>   12
Subordinated Notes Tendered Hereby." A newly issued Note for the principal
amount of Notes submitted but not tendered will be sent to such Holder as soon
as practicable after the Expiration Date. All Notes delivered to the Exchange
Agent will be deemed to have been tendered in full unless otherwise indicated.

         Any Notes tendered pursuant to the Exchange offer may be withdrawn at
any time prior to the Expiration Date, after which tenders of Notes are
irrevocable.

         To withdraw a tender of Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent by 5:00 p.m., New York City time, on the Expiration Date. Any such notice
of withdrawal must (i) specify the name of the person having deposited the Notes
to be withdrawn (the "Depositor"), (ii) identify the Notes to be withdrawn
(including the certificate or registration number(s) and principal amount of
such Notes, or, in the case of Notes transferred by book-entry transfer, the
name and number of the account at the DTC to be credited), (iii) be signed by
the Depositor in the same manner as the original signature on this Letter of
Transmittal (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Notes
register the transfer of such Notes into the name of the Depositor withdrawing
the tender, (iv) specify the name in which such Notes are to be registered, if
different from that of the Depositor and (v) include a statement that such
Holder is withdrawing his election to have such Notes exchanged. All questions
as to the validity, form and eligibility (including time of receipt) of such
notices will be determined by the Company, whose determination shall be final
and binding on all parties. Any Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer, and no Exchange Notes
will be issued with respect thereto unless the Notes so withdrawn are validly
retendered. Any Notes which have been tendered but which are not accepted for
exchange, will be returned to the Holder thereof without cost to such Holder as
soon as practicable after withdrawal, rejection of tender or termination of
Exchange Offer.

4. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
ENDORSEMENTS; GUARANTEE OF SIGNATURES.

         If this Letter of Transmittal is signed by the registered Holder(s) of
the Notes tendered hereby, the signature must correspond with the name(s) as
written on the face of the certificates without alteration or enlargement or any
change whatsoever. If this Letter of Transmittal is signed by a participant in
the Depository, the signature must correspond with the name as it appears on the
security position listing as the owner of the Notes. If any of the Notes
tendered hereby are owned of record by two or more joint owners, all such owners
must sign this Letter of Transmittal.

         If a number of Notes registered in different names are tendered, it
will be necessary 

                                       12
<PAGE>   13
to complete, sign and submit as many separate copies of this Letter of
Transmittal as there are different registrations of Notes.

         Signatures on this Letter of Transmittal or a notice of withdrawal, as
the case may be, must be guaranteed by an Eligible Institution unless the Notes
tendered hereby are tendered (i) by a registered Holder who has not completed
the box entitled "Special Registration Instructions" or "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution.

         If this Letter of Transmittal is signed by the registered Holder or
Holders of Notes (which term, for the purposes described herein, shall include a
participant in the Depository whose name appears on a security listing as the
owner of the Notes) listed and tendered hereby, no endorsements of the tendered
Notes or separate written instruments of transfer or exchange are required. In
any other case, the registered Holder (or acting Holder) must either properly
endorse the Notes or transmit properly completed bond powers with this Letter of
Transmittal (in either case, executed exactly as the name(s) of the registered
Holder(s) appear(s) on the Notes, and, with respect to a participant in the
Depository whose name appears on a security position listing as the owner of
Notes, exactly as the name of the participant appears on such security position
listing), with the signature on the Notes or bond power guaranteed by an
Eligible Institution (except where the Notes are tendered for the account of an
Eligible Institution).

         If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.

5.       SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.

         Tendering Holders should indicate, in the applicable box, the name and
address (or account at the Depository) in which the Exchange Notes or substitute
Notes for principal amounts not tendered or not accepted for exchange are to be
issued (or deposited), if different from the names and addresses or accounts of
the person signing this Letter of Transmittal. In the case of issuance in a
different name, the employer identification number or social security number of
the person named must also be indicated, and the tendering Holder should
complete the applicable box.

         If no instructions are given, the Exchange Notes (and any Notes not
tendered or not accepted) will be issued in the name of and sent to the acting
Holder of the Notes or deposited at such Holder's account at the Depository.

                                       13
<PAGE>   14
6.       TRANSFER TAXES.

         The Company shall pay all transfer taxes, if any, applicable to the
exchange of Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes or Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered Holder of the Notes
tendered, or if tendered Notes are registered in the name of any person other
than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered Holder or any other person) will be payable by the tendering Holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed directly to
such tendering Holder. Except as provided in this Instruction 6, it will not be
necessary for transfer stamps to be affixed to the Notes listed in the Letter of
Transmittal.

7.       WAIVER OF CONDITIONS.

         The Company reserves the right, in its reasonable judgment, to waive,
in whole or in part, any of the conditions to the Exchange Offer set forth in
the Prospectus. .

8.       MUTILATED, LOST, STOLEN OR DESTROYED NOTES.

         Any Holder whose Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above for further
instructions.

9.       REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

         Questions relating to the procedure for tendering, as well as requests
for additional copies of the Prospectus and this Letter of Transmittal may be
directed to the Exchange Agent at the address and telephone number set forth
above. In addition, all questions relating to the Exchange Offer, as well as
requests for assistance or additional copies of the Prospectus and this Letter
may be directed to Chief Financial Officer, Unicco Service Company, Four Copley
Place, Boston, MA 02116.

10.      VALIDITY AND FORM.

         All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Notes and withdrawal of tendered Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and all
Notes not properly tendered or any Notes the Company's acceptance of which
would, in the opinion of counsel for the 

                                       14
<PAGE>   15
Company, be unlawful. The Company also reserves the right to waive any
irregularities or conditions of tender as to particular Notes. The Company's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Notes must be cured within such time as the Company shall determine. Neither
the Company, the Exchange Agent nor any other person shall be under any duty to
give notification of defects or irregularities with respect to tenders of Notes,
nor shall any of them incur any liability for failure to give such notification.
Tenders of Notes will not be deemed to have been made until such irregularities
have been cured or waived. Any Notes received by the Exchange Agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned without cost to such holder by the Exchange
Agent to the tendering Holders of Notes, unless otherwise provided herein, as
soon as practicable following the Expiration Date.



                                       15
<PAGE>   16
                            IMPORTANT TAX INFORMATION

         Under federal income tax law, a Holder tendering Notes is required to
provide the Exchange Agent with such Holder's correct TIN on Substitute Form W-9
above. If such Holder is an individual, the TIN is the Holder's social security
number. The Certificate of Awaiting Taxpayer Identification Number should be
completed if the tendering Holder has not been issued a TIN and has applied for
a number or intends to apply for a number in the near future. If the Exchange
Agent is not provided with the correct TIN, the Holder may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, payments that are
made to such Holder with respect to tendered Notes may be subject to backup
withholding. Certain Holders (including, among others, all domestic corporations
and certain foreign individuals and foreign entities) are not subject to these
backup withholding and reporting requirements. Such a Holder, who satisfies one
or more of the conditions set forth in Part 2 of the Substitute Form W-9, should
execute the certification following such Part 2. In order for a foreign Holder
to qualify as an exempt recipient, that Holder must submit to the Exchange Agent
a properly completed Internal Revenue Service Form W-8, signed under penalties
of perjury, attesting to that Holder's exempt status. Such forms can be obtained
from the Exchange Agent.

         If backup withholding applies, the Exchange Agent is required to
withhold 31% of any amounts otherwise payable to the Holder. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.

10.      PURPOSE OF SUBSTITUTE FORM W-9

         To prevent backup withholding on payments that are made to a Holder
with respect to the Exchange Notes, the Holder is required to notify the
Exchange Agent of his or her correct TIN by completing the form herein
certifying that the TIN provided on Substitute Form W-9 is correct (or that such
Holder is awaiting a TIN) and that (i) such Holder is exempt, (ii) such Holder
has not been notified by the Internal Revenue Service that he or she is subject
to backup withholding as a result of failure to report all interest or dividends
or (iii) the Internal Revenue Service has notified such Holder that he or she is
no longer subject to backup withholding.

11.      WHAT NUMBER TO GIVE THE EXCHANGE AGENT

         Each Holder is required to give the Exchange Agent the social security
number or employer identification number of the record Holder(s) of the Notes.
If Notes are in more than one name or are not in the name of the actual Holder,
consult the instructions on 

                                       16
<PAGE>   17
Internal Revenue Service Form W-9, which may be obtained from the Exchange
Agent, for additional guidance on which number to report.

12.      CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

         If the tendering Holder has not been issued a TIN and has applied for a
number or intends to apply for a number in the near future, write "Applied For"
in the space for the TIN on Substitute Form W-9, sign and date the form and the
Certificate of Awaiting Taxpayer Identification Number and return them to the
Exchange Agent. If such certificate is completed and the Exchange Agent is not
provided with the TIN within 60 days, the Exchange Agent will withhold 31% of
all payments made thereafter until a TIN is provided to the Exchange Agent.

         IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER
WITH NOTES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED
DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE
AGENT ON OR PRIOR TO THE EXPIRATION DATE.

         PRIVACY ACT NOTICE.--Section 6109 requires most recipients of
dividends, interest or other payments to give taxpayer identification numbers to
payers who must report the payments to IRS. IRS uses the numbers for
identification purposes and to help verify the accuracy of tax returns. Payers
must be given the numbers whether or not recipients are required to file tax
returns. Payers must generally withhold 31% of taxable interest, dividend and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payer. Certain penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. If you fail
to furnish your correct taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure which is due to reasonable
cause and not to willful neglect.

(2) CIVIL PENALTY FOR FALSE STATEMENTS WITH RESPECT TO WITHHOLDING. If you make
a false statement with no reasonable basis which results in no imposition of
backup withholding, you are subject to a penalty of $500.

                                       22
<PAGE>   23
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. Willfully falsifying
certifications or affirmations, may subject you to criminal penalties including
fines and/or imprisonment.

(4) MISUSE OF TAXPAYER IDENTIFICATION NUMBERS. If the payer discloses or uses
taxpayer identification numbers in violation of Federal law, the payer may be
subject to civil and criminal penalties.

         FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.
