                                    PART I

ITEM 1. BUSINESS

GENERAL

     Muzak Holdings LLC (together with its wholly owned subsidiaries,
collectively the "Company") is the leading provider of business music
programming in the United States based on market share. Together with its
independent franchisees, the Company serves an installed base of approximately
300,000 business locations nationwide. The Company and its independent
franchisees also sell, install and maintain electronic equipment related to the
Company's business.

     The Company's nationwide network divides the country into 168 territories,
of which 50 are served by the Company's owned operations, and the remaining 118
are served by the Company's independent franchisees. The independent franchisees
have exclusive licenses to sell the Company's products and to use the Company's
trademarks in their territories. As of December 31, 1999, ABRY Partners, LLC and
its respective affiliates collectively own approximately 68% of the voting
interests in the Company.

     The Company's customers typically enter into a noncancelable five-year
contract that renews automatically for at least one five-year term unless
specifically terminated at the initial contract expiration date. The average
length of service per customer is approximately 12 years. The Company typically
makes an initial one-time installation investment per location, in exchange for
recurring monthly fees. For music clients generated by the independent
franchisees, the Company receives a net monthly royalty fee for each client
location in exchange for music programming. The Company does not incur a
capital outlay for a new client location generated by a independent franchisee.



DEVELOPMENTS

ACQUISITIONS

     The Company, formerly known as ACN Holdings, LLC, was formed in September
1998 pursuant to the laws of Delaware. Muzak LLC, a wholly owned subsidiary of
the Company, owns and operates franchisees. Muzak LLC began its operations on
October 7, 1998 with the acquisition of the independent franchisees in the
Baltimore, Charlotte, Hillsborough, Kansas City, St. Louis, Jacksonville,
Phoenix, and Fresno areas from Audio Communications Network, Inc. (the
"Predecessor Company") for $66.8 million. On March 18, 1999, Muzak Limited
Partnership ("Old Muzak") merged with and into Audio Communications Network LLC
("ACN"). At the time of the merger, ACN changed its name to Muzak LLC. Under the
terms of the agreement, the Company paid total consideration of $274.2 million,
which is comprised of the following: $125.5 million cash consideration, $114.9
million consideration in the tender offer and consent solicitation for the 10%
Senior Notes due 2003 of Old Muzak, $15.9 million for debt repayment of Old
Muzak outstanding obligations and assumed $17.9 million of other obligations. In
addition, at the time of the merger, the Company repaid $41.7 million borrowed
from ABRY Broadcast Partners by ACN in October 1998 in connection with the
acquisition of the Company's independent franchisees from the Predecessor
Company and converted $0.7 million into Class A units of the Company.

     In 1999, prior to the merger, the Company made the following acquisitions:


   o On January 15, 1999, the Company acquired all of the outstanding stock of
    Business Sound, Inc. for approximately $4.1 million which included 3,661
    Class A units of the Company. Business Sound was the Company's independent
    franchisee for the New Orleans, Louisiana and Mobile, Alabama areas.

   o On February 24, 1999, the Company acquired all of the outstanding stock
    of Electro Systems for approximately $0.7 million, which included 650
    Class A units of the Company, and assumed certain non-recourse debt.
    Electro Systems was the Company's independent franchisee located in Panama
    City, Florida.


                                       3
<PAGE>

     The Company made thirteen acquisitions between the merger of Old Muzak and
ACN on March 18, 1999 and December 31, 1999. The table below provides
information regarding these acquisitions (in millions, except for number of
units).

PRODUCTS

     The Company's core product is Audio Architecture, and complementary
products include Audio Marketing and Video Architecture. The Company believes
that the products assist customers in strengthening their brand images and
enhancing the experiences of their customers.

     Audio Architecture is the art of creating business music programming
designed to enhance a client's brand image. The Company has an in-house staff
of audio architects that analyzes a variety of music to develop and maintain 60
core music programs in 10 genres that appeal to a wide range of tastes.
Programs include current top-of-the-charts hits to jazz, classic rock, urban,
country, Latin, classical music and others. The Company's audio architects
update the music programs on a daily basis, incorporating the continuous
release of new music recordings and drawing from the Company's extensive music
library. In designing the music programs, the audio architects use proprietary
computer software that allows them to efficiently access the extensive library,
avoid repeated songs and manage tempo and music variety to provide customers
with high quality, seamlessly arranged programs.

     As a complement to Audio Architecture, the Company's Audio Marketing
creates customized music and messages that allow customers' telephone systems to
deliver targeted music and messaging during their customers time on hold. The
Company has the in-house capability to write, edit, produce and duplicate
messages. The Company's fully integrated sound studios and editing and tape
duplication facilities provide flexibility in responding to client's needs.

     Video Architecture is video programming designed to enhance the brand
personality of the Company's customers by entertaining, informing and
captivating their customers. The Company has a library of video programs from
which customer specific programming is produced.

     The Company's net sales of Audio Architecture, Audio Marketing and Video
Architecture were $65.4 million, $8.6 million, and $2.2 million, respectively
in 1999.

     In connection with the sale of Audio Architecture, Audio Marketing, and
Video Architecture products, the Company sells and leases various audio and
video system-related products, principally sound systems. As part of a typical
music programming contract, the Company provides music receiving or playback
equipment to its customers. The Company's music clients generally purchase or
lease audio equipment that supplements the music receiving or playback
equipment. The Company also sells, installs, and maintains non-music related
equipment, such as intercom, paging and drive-thru systems.


CUSTOMERS

     The Company provides its products to numerous types of businesses
including specialty retailers, restaurants, department stores, supermarkets,
drug stores, financial institutions, hotels, golf clubs, health and fitness
centers, business offices, manufacturing facilities, and medical centers.
During 1999, none of the Company's customers represented more than 2% of
revenues, and less than 2% of revenues were for services provided to customers
located outside of the United States. However, the Company has 16 independent
franchisees located outside the United States that serve areas in Canada,
Mexico, Bermuda, Japan, Indonesia, New Zealand, Europe, and Peru.


NATIONWIDE AFFILIATE NETWORK

     The Company has a nationwide network that divides the country into 168
affiliate territories, of which 50 are served by the Company's owned operations
and the remaining 118 are served by the Company's independent franchisees. The
Company's owned operations generally operate in the larger and the more
populated territories. The Company's business relationships with its
independent franchisees are governed by independent affiliate agreements that
have ten-year renewable terms. In exchange for the exclusive right to offer and
sell the Company's products, the independent franchisees pay a monthly fee
based on the number of businesses within its territory. In addition, the
Company also receives a royalty or a wholesale fee depending on the type of
product sold.


DISTRIBUTION SYSTEMS

     The Company transmits its offerings through various mediums including
direct broadcast satellite transmission, local broadcast transmission, audio
and videotapes and compact discs. During 1999, the Company served its customer
locations through the following means: approximately 61% through direct
broadcast satellite transmission, approximately 29% through local broadcast
technology, and approximately 10% through on-premises tapes or compact discs.

     The Company's transmissions via direct broadcast satellite to customers
are primarily from transponders leased from Microspace and EchoStar Satellite
Corporation ("EchoStar"). Microspace provides the Company with facilities for
uplink


                                       5
<PAGE>

transmission of medium-powered direct broadcast satellite signals to the
transponders. Microspace, in turn, leases its transponder capacity on
satellites operated by third parties. The term of the Company's principal
transponder lease with Microspace is projected to end in 2005.

     The Company also furnishes music channels to commercial and residential
subscribers over EchoStar's satellite system. The Company furnishes 60 music
channels to commercial subscribers and 30 music channels to residential
subscribers over EchoStar's satellite system. Pursuant to the agreements with
EchoStar, EchoStar pays the Company a programming fee for each of its
residential subscribers and pays the Company's independent franchisees a
commission for sales made by EchoStar or its agents to commercial subscribers
in an affiliate's territory. The Company pays EchoStar a fee for uplink
transmission of music channels to its customers and rents space at EchoStar's
Cheyenne, Wyoming uplink facility. The Company also pays EchoStar a royalty and
combined access fees on music programs sold by the Company which are
distributed by EchoStar to commercial subscribers. EchoStar has the right to
cancel its distribution of the 30 music programs to residential subscribers at
any time upon 60 days notice. Upon such cancellation, EchoStar must pay the
Company the depreciated book value of its capital investment in equipment to
support the residential music channels and continue to provide 2.4 megahertz of
transponder capacity for use in serving commercial subscribers. In such event,
the Company would only be able to provide 30 music programs and would need to
lease other transponder space in order to continue providing the other 30 music
programs. The Company would also lose the programming fee generated by
EchoStar's residential subscribers. The Company's agreements with EchoStar are
projected to end in 2010.

     During the first quarter of 2000, EchoStar approached the Company and
expressed a desire to reassess the business terms that pertain to EchoStar's
distribution of the residential music channels. The Company and EchoStar are in
the process of negotiating an understanding in which the programming fees
earned by the Company and paid by EchoStar in connection with the residential
music channels may be eliminated in consideration for a long-term supply
agreement with respect to satellite services. The Company expects to conclude
negotiations prior to the third quarter of 2000.


COMPETITION

     The Company competes with many local, regional, national and international
providers of business music and business services. National competitors include
AEI Music Network, Inc., DMX, Inc. and Music Choice. Local and regional
competitors are typically smaller entities that target businesses with few
locations. Some of the Company's competitors may have substantially greater
financial, technical, personnel or other resources than the Company.

     There are numerous methods by which our existing and future competitors
deliver programming, including various forms of DBS services, wireless cable,
fiber optic cable, digital compression over existing telephone lines, advance
television broadcast channels, Digital Audio Radio Service ("DARS"), and the
Internet. The Company may not be able to compete successfully with existing or
potential new competitors, maintain or increase current market share, compete
effectively with competitors that adopt new delivery methods and technologies,
or keep pace with discoveries or improvements in the communications, media and
entertainment industries such that existing technologies or delivery systems on
which the Company relies will not become obsolete. In addition, the terms of
the Company's debt impose operational and financial restrictions that may
inhibit the Company's ability to compete.

     The Company principally competes on the basis of service, the quality and
variety of music programs, versatility and flexibility, the availability of
non-music services and, to a lesser extent, price. Even though the Company is
seldom the lowest-priced provider of business music in a territory, the Company
believes it can compete effectively on all these bases due to widespread
recognition of the MUZAK(R) trademark, the Company's nationwide network, the
quality and variety of music programming, the talent of the Company's audio
architects and the Company's multiple delivery systems.


SALES AND MARKETING

     The Company employs a direct sales process in marketing products, which is
focused on securing new client contracts and renewing existing contracts.
Customer agreements typically have a non-cancelable term of five years and
renew automatically for at least one additional five-year term unless
specifically terminated at the initial contract expiration date. Repeat clients
comprise the core of the account base. The Company has local, national, and
regional sales forces. Local account executives typically focus on customers
that have fewer than 50 locations.

MUSIC LICENSES

     The Company licenses rights to rerecord and distribute music from a
variety of sources and pays royalties to songwriters and publishers through
contracts negotiated with performing rights societies such as the American
Society of Composers, Authors and Publishers ("ASCAP"), Broadcast Music, Inc.
("BMI"), and the Society of European Stage Authors and Composers ("SESAC").

     The industry-wide agreement between business music providers and BMI
expired in December 1993. Since this time the Company has been operating under
an interim agreement pursuant to which the Company has continued to pay
royalties at the 1993 rates. Business music providers and BMI have been
negotiating the terms of a new agreement. The Company is involved in a rate
court proceeding, initiated by BMI in Federal Court in New York. At issue are
the music license fees payable by the Company and its owned operations as well
as licensed independent franchisees to BMI. The period from which such
"reasonable" license fees are payable covers the period January 1, 1994 to
December 31, 1999, and likely several years thereafter. BMI contends that those
fee levels understate reasonable fee levels by as much as 100%. The Company
vigorously contests BMI's assessment. The eventual court ruling setting final
fees for the period covered may require retroactive adjustment, upward or
downward, likely back to January 1, 1994, and possibly will also entail payment
of pre-judgment interest. Discovery in the proceeding has commenced and is not
yet completed. A trial date has not been set.

     The industry wide agreement between business music providers and ASCAP
expired in May 1999. Negotiations between ASCAP and the Company began in June
1999, and the Company has continued to pay ASCAP royalties at the 1999 rates. In
1999, the Company paid approximately $4.1 million in royalties to ASCAP and BMI.


GOVERNMENT REGULATION

     The Company is subject to governmental regulation by the United States and
the governments of other countries in which it provides services. The Company
provides music services in a few areas in the United States through 928 to 960
megahertz frequencies licensed by the Federal Communications Commission
("FCC"). Additionally, the FCC licenses the frequencies used by satellites on
which the Company transmits direct broadcast satellite services in the United
States. If the FCC or any other person revokes or refuses to extend any of
these licenses, the Company would be required to seek alternative transmission
facilities. Laws, regulations and policy, or changes therein, in other
countries could also adversely affect the Company's existing services or
restrict the growth of its business in these countries.


EMPLOYEES

     As of December 31, 1999, the Company had 1,286 full-time and 38 part-time
employees. Approximately 100 of the technical and service personnel are covered
by eight union contracts, all of which are with the International Brotherhood
of Electrical Workers. All of the contracts, with the exception of one, expire
on dates ranging from October 31, 2000 to January 31, 2003. One of the
International Brotherhood of Electrical Workers contracts that covers less than
10 employees expired on February 28, 2000 and the Company is in the process of
negotiating a replacement agreement. Management believes that the Company's
relations with its employees and with the unions that represent them are
generally good.


ITEM 2. PROPERTIES

     The Company's headquarters are located in Charlotte, North Carolina and
consist of approximately 10,000 square feet. As of December 31, 1999, the
Company also occupied approximately 80,000 square feet in Seattle, Washington
which served as Old Muzak's headquarters. In order to achieve operational
efficiencies and consolidate geographically disbursed business units, the
Company decided to relocate its headquarters to Fort Mill, South Carolina and
has entered into a lease which obligates the landlord to construct a 100,000
square foot facility in Fort Mill, South Carolina which will accommodate the
Company's headquarters, the Charlotte owned operation, and several of its other
divisions. The facility is currently under construction and is expected to be
completed during the third quarter of 2000. The Company has approximately 55
local sales offices in various locations, office and satellite uplink
facilities in Raleigh, North Carolina and Cheyenne, Wyoming and warehouses in
various locations. Approximately 95% of the total square footage of these
facilities is leased and the remainder is owned. In January 2000, the Company
entered into a lease for approximately 29,000 square feet to accommodate
additional headquarter employees on a temporary basis in Charlotte, North
Carolina. The Company believes that its facilities are sufficient to meet
existing needs.

ITEM 3. LEGAL PROCEEDINGS

     The Company is subject to various proceedings in the ordinary course of
business. Management believes that such proceedings are routine in nature and
incidental to the conduct of its business, and that none of such proceedings, if
determined adversely to the Company, would have a material adverse effect on the
consolidated financial condition or results of operations of the Company.

ITEM 5. MARKET FOR REGISTRANTS' COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     The Company does not have an established public trading market for its
equity securities. The equity securities of the Company are held by MEM Holdings
LLC, CBC Acquisition Company, Inc., and by current or former management. ABRY
Broadcast Partners III and ABRY Broadcast Partners II are the beneficial owners
of MEM Holdings.

     The Company's bank agreement, the indentures with respect to the Senior
Subordinated and Floating Rate Notes of the Company, and the indenture with
respect to the Company's Senior Discount Notes restrict the ability of the
Company to make dividends and distributions in respect of their equity.

     During 1999, the Company issued its membership units in the following
     transactions:

   o In January, the Company issued 3,661 Class A Units to MEM Holdings LLC in
     connection with the Company's acquisition of Business Sound.

     Corporation and 0.886 Class B-4 Units to management and 98.51 B-4 units to

   o In November, the Company issued 25 Class A Units to management and issued
     100 Class A units to the principal shareholder of Audio Environments, Inc.
     and Background Music Broadcasters, Inc. in connection with this
     acquisition on November 1, 1999.

   o In November, Capstar Broadcasting Corporation transferred 15,920.915

a public offering.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

    This Form 10-K contains statements which, to the extent they are not
historical fact, constitute forward-looking statements within the meaning of
Section 27A of the securities Act of 1933 and Section 21E of the Securities and
Exchange Act of 1934 (the "Safe Harbor Acts"). All forward-looking statements
involve risks and uncertainties. The forward-looking statements in this Form
10-K are intended to be subject to the safe harbor protection provided by the
Safe Harbor Acts.

     Risks and uncertainties that could cause actual results to vary materially
from those anticipated in the forward-looking statements included in this Form
10-K include industry-based factors such as the level of competition in the
business music industry, changes in consumer preference, competitive pricing,
concentrations in and dependence on satellite delivery capabilities, rapid
technological changes, as well as factors more specific to the Company such as
the substantial leverage of the Company, limitations imposed by the Company's
debt facilities, and changes made in connection with the integration of
operations acquired by the Company.

GENERAL

     The Company is the leading provider of business music programming in the
United States. Together with its independent franchisees, the Company serves an
installed base of approximately 300,000 business locations nationwide. The
Company and its independent franchisees also sell, install and maintain
electronic equipment related to the Company's business.

     The Company, formerly known as ACN Holdings, LLC, was formed in September
1998 pursuant to the laws of Delaware. Audio Communications Network LLC ("ACN")
began its operations on October 7, 1998 with the acquisition of the independent
franchisees in the Baltimore, Charlotte, Hillsborough, Kansas City, St. Louis,
Jacksonville, Phoenix, and Fresno areas from Audio Communications Network, Inc.
(the "Predecessor Company") for $66.8 million. On March 18, 1999, Muzak Limited
Partnership ("Old Muzak") merged with and into ACN. At the time of the merger,
ACN changed its name to Muzak LLC. Under the terms of the agreement, the Company
paid total consideration of $274.2 million, which consisted of the following:
$125.5 million cash consideration, $114.9 million consideration in the tender
offer and consent solicitation for the 10% Senior Notes due 2003 of Old Muzak,
$15.9 million for debt repayment of Old Muzak outstanding obligations and
assumed $17.9 million of other obligations. In addition, at the time of the
merger, the Company repaid $41.7 million borrowed from ABRY Broadcast Partners
by ACN in October 1998 in connection with the acquisition of the Company's
independent franchisees from the Predecessor Company and converted $0.7 million
into Class A units. Since the merger, the Company has acquired thirteen
businesses for total consideration of $73.9 million, which included 16,476 Class
A units of the Company.

     In 1999, prior to the merger, the Company made the following acquisitions:


   o On January 15, 1999, the Company acquired all of the outstanding stock of
     Business Sound, Inc. for approximately $4.1 million, which included 3,661
     Class A units. Business Sound was the Company's independent franchisee for
     the New Orleans, Louisiana and Mobile, Alabama areas.


                                       9
<PAGE>

   o On February 24, 1999, the Company acquired all of the outstanding stock of
     Electro Systems for approximately $0.7 million, which included 650 Class A
     units, and assumed certain non-recourse debt of $2.4 million. Electro
     Systems was the Company's independent franchisee located in Panama City,
     Florida.

     The Company made thirteen acquisitions between the merger of Old Muzak and
ACN on March 18, 1999 and December 31, 1999. The table below provides
information regarding these acquisitions (in millions, except for number of
units).

RECENT DEVELOPMENTS

ADDITIONAL FINANCING

     In January 2000, the Company entered into an indenture for up to $50.0
million Senior Subordinated Floating Rate Notes (the "Floating Rate Notes").
The Floating Rate Notes are available to be drawn up to $50.0 million in
increments of no less than $2.5 million to fund acquisitions. The Floating Rate
Notes will be available for drawdowns until July 31, 2000. Commitments on all
amounts undrawn under the Floating Rate Notes by July 31, 2000 will expire and
will be ineligible for future draw downs. The Floating Rate Notes may be
redeemed at 100% if redeemed before July 31, 2000 and at 101.50%


                                       10
<PAGE>

if redeemed August 1, 2000 through October 31, 2000. If the Company does not
redeem the Floating Rate Notes by November 1, 2000, the Floating Rate Notes
will automatically convert into fixed-rate permanent notes due March 2009. As
of March 29, 2000, $25.0 million of the Floating Rate Notes were outstanding.

     Also, in February 2000, the Company received approximately $10.6 million
in equity contributions from its members. The proceeds of the equity
contributions will be used to make repayments on the revolving loan (as defined
below) and to fund acquisitions and for general corporate purposes.


ACQUISITIONS

     On February 2, 2000, the Company acquired certain of the net assets of
Quincy Broadcasting Company, a Delaware corporation, for approximately $0.4
million. Quincy Broadcasting Company was the Company's independent franchisee
located in Quincy, Illinois.

     On February 2, 2000, the Company acquired certain of the assets and
assumed certain obligations of General Communications Corporation ("On Hold
America"), an Indiana corporation, for approximately $0.9 million. On Hold
America was an audio marketing business serving areas primarily in Indiana,
Georgia, Florida, and Ohio.

     On February 2, 2000, the Company acquired certain of the assets and
certain obligations of Texas Sound Co. Ltd for approximately $0.4 million.
Texas Sound Co. Ltd was a provider of business music and audio marketing
services.

     On February 24, 2000, the Company acquired Telephone Audio Productions,
Inc., ("Sold on Hold Communications"), a Texas corporation, for approximately
$3.7 million. Sold on Hold Communications was an audio marketing and messaging
business serving various markets in the United States.

     On March 24, 2000, the Company acquired the stock of Vortex Sound
Communications Company, Inc., ("Vortex") for approximately $9.2 million, which
included 802 Class A units. Vortex was the Company's independent franchisee
located in Washington, DC.


REVENUES AND EXPENSES

     The Company derives the majority of its revenues from the sale of business
music products. The core product is Audio Architecture and its two
complementary products are Audio Marketing and Video Architecture. These
revenues are generated by clients, who pay monthly subscription fees under
noncancelable five year contracts.

     The Company also derives revenues from the sale and lease of audio
system-related products, principally sound systems and intercoms, to business
music clients and other clients. In addition, the Company sells electronic
equipment, such as proprietary tape playback equipment and other audio and
video equipment to franchisees to support the sale of business music services.
Installation, service and repair revenues consist principally of revenues from
the installation of sound systems and other equipment that is not expressly
part of a business music contract, such as paging, security and drive-through
systems. These revenues also include revenue from the installation, service and
repair of equipment installed under a business music contract. Music contract
installation revenues are deferred and recognized over the term of the
respective contracts.

     The cost of revenues for business services consists primarily of broadcast
delivery, programming and licensing associated with providing music and other
business programming to a client or a franchisee. The cost of revenues for
equipment represents the purchase cost plus handling, shipping and warranty
expenses. The cost of revenues for installation, service and repair consists
primarily of service and repair labor and labor for installation that is not
associated with new client locations. Installation costs associated with new
client locations are capitalized and charged to depreciation expense over the
estimated life of the clients' contract.

     The Company's customers typically enter into a noncancelable five-year
contract that renews automatically for at least one five-year term unless
specifically terminated at the initial contract expiration date. The average
length of service per customer is approximately 12 years. The Company typically
makes an initial one-time installation investment per location, in exchange for
recurring monthly fees. For music clients generated by the independent
franchisees, the Company receives a net monthly royalty fee for each client
location in exchange for music programming. The Company does not incur a
capital outlay for a new client location generated by a independent franchisee.


     The business music industry remains highly fragmented, with numerous
independent operators. The Company plans to pursue acquisitions of in market
competitors and of its independent franchisees. Through acquisitions, the
Company expects to realize cost savings by eliminating duplicative programming,
distribution, sales and marketing, and technical and other general
administrative expenses.


                                       11
<PAGE>

     The business music industry is influenced by the recording industry,
performing rights societies, government regulations, technological
advancements, satellite capabilities, and competition. The Company must license
rights to rerecord and distribute music and is reliant on third parties for
satellite capabilities.

     Selling, general and administrative expenses include salaries, benefits,
commissions, travel, marketing materials, training and occupancy costs
associated with staffing and operating local and national sales offices. These
expenses also include personnel and other costs in connection with the
Company's headquarters functions. Sales commissions are capitalized and charged
as selling, general and administrative expense over the typical contract term
of five years. If a client contract is terminated early, the unamortized sales
commission is typically recovered from the salesperson.

RESULTS OF OPERATIONS

     Set forth below are discussions of the results of operations for Muzak
Holdings LLC, ACN, Old Muzak and the Predecessor Company for the periods
indicated. ACN had no operations until it acquired the Predecessor Company in
October 1998. ACN changed its name to Muzak LLC in connection with its merger
with Old Muzak. The fiscal year ended December 31, 1999 includes operating
results of ACN Holdings LLC for the period from January 1, 1999 to March 17,
1999, and for Muzak Holdings LLC for the period March 18, 1999 to December 31,
1999.


MUZAK HOLDINGS LLC -- FISCAL YEAR ENDED DECEMBER 31, 1999

     The Company did not compare the results for the year ended December 31,
1999 to the prior period as the prior period does not include a full year of
operations and the Company made numerous material acquisitions during 1999. As
a result, the comparison of 1999 to the period October 7, 1998 to December 31,
1998 is not meaningful.

     REVENUES. Revenues totaled $130.0 million for the year ended December 31,
1999, comprised of $92.1 million business music revenues and $37.9 million
equipment and related services. Business music revenues and equipment and
related revenues from the acquisitions subsequent to the merger of ACN, Old
Muzak, and Capstar were $5.0 million and $1.0 million, respectively.

     GROSS PROFIT. Gross profit was $81.7 million, and 62.8% as a percentage of
revenues for the year ended December 31, 1999. The general increase in gross
margin over the quarters during 1999 is due to growth in higher margin business
services as well as the acquisition of competitors and independent franchisees
business music contracts. Gross profit for the acquisitions subsequent to the
merger of ACN, Old Muzak, and Capstar was $3.2 million.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general, and
administrative expenses were $42.5 million, comprised of $16.5 million of sales
and marketing expenses and $26.0 million of general and administrative
expenses. Duplicative facilities and expenses related to integrating
acquisitions resulted in an increase in selling, general, and administrative
expenses during 1999. As a percentage of total revenues, selling, general and
administrative expenses were 32.7% for the year ended December 31, 1999.

     DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization was
$36.5 million for the year ended December 31, 1999. Amortization expense
generally increased in the quarters throughout 1999 due to the intangibles
related to the acquisitions of competitors' and independent franchisees
business music contracts during 1999.

     INTEREST EXPENSE. Interest expense, net of interest income, was $29.4
million for the year ended December 31, 1999. Interest expense was comprised
primarily of expenses related to the Senior Notes and to the Senior Credit
facility.

     INCOME TAX BENEFIT. Income tax benefit was $0.4 million for the year ended
December 31, 1999 and related to the Company's corporate subsidiaries. The
Company is a limited liability company and is treated as a partnership for
income tax purposes.


MUZAK HOLDINGS LLC -- PERIOD FROM OCTOBER 7, 1998 TO DECEMBER 31, 1998

     Revenues totaled $5.9 million for the period ended December 31, 1998,
comprised primarily of business music revenues. For the same period, cost of
sales totaled $2.6 million, resulting in a gross profit margin of 56.8%. Total
selling, general, and administrative expenses for the period totaled $1.8
million, comprised principally of salary, benefits, and overhead expenses.


                                       12
<PAGE>

PREDECESSOR COMPANY -- AUDIO COMMUNICATIONS NETWORK INC. -- PERIOD FROM JANUARY
1, 1998 TO OCTOBER 6, 1998 COMPARED TO THE NINE MONTH PERIOD ENDED SEPTEMBER
30, 1997

     REVENUES. Total revenues increased 60.2% from $11.8 million in 1997 to
$18.9 million in 1998, primarily as a result of the impact of a reverse
acquisition which occurred in May 1997, as well as the growth in business music
revenues and equipment sales and related services

     GROSS PROFIT. Total gross profit increased 35.0% from $8.0 million in 1997
to $10.7 million in 1998. The Predecessor Company's gross margin in 1998 was
56.7%. Such gross margin is not comparable to the prior period as a result of a
reverse acquisition in 1997. The 1998 gross margin was negatively impacted by
approximately 3.0% or $0.6 million resulting from one-time charges related to
the Galaxy IV satellite failure.

     SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES. Selling, general, and
administrative expenses increased 84.7% from $3.9 million in 1997 to $7.2
million in 1998. Such increase was primarily the result of the impact of a
reverse acquisition in 1997, the growth in business music revenues and
equipment sales and related services and approximately $0.8 million being
incurred in 1998 pertaining to transaction costs related to the sale of Audio
Communications Network Inc. in October 1998.


OLD MUZAK -- YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31,
1997

     REVENUES. Total revenues increased 9.4% from $91.2 million in 1997 to
$99.7 million in 1998 principally as a result of an 11.1% increase in music and
other business services revenues and a 6.1% increase in equipment sales and
related services. Music and other business services revenues increased due to
an increase in the number of broadcast music subscribers, sales growth and the
acquisition of competitors' business music contracts, together with an increase
in the royalties paid by independent franchisees resulting from growth in the
broadcast music subscribers in the franchise network. Royalties and other fees
from independent franchisees and international distributors included in
broadcast music revenues accounted for $8.9 million or 8.9% of Old Muzak's
revenues in 1998, compared with $8.8 million or 9.6% of Old Muzak's revenues in
1997. The continued decrease in the surcharges assessed to independent
franchisees for satellite transmission costs was offset by increased growth in
royalties related to new subscriber billing. Equipment and installation
revenues increased 4.7% and 8.7%, respectively due to the expansion of national
accounts.

     GROSS PROFIT. Total gross profit increased 13.4% from $50.5 million in
1997 to $57.2 million in 1998. As a percentage of total revenues, gross profit
increased from 55.4% in 1997 to 57.4% in 1998. The improvement in gross profit
percentage in 1998 was due to growth of higher margin business services, such
as broadcast music, audio marketing, and on-premise music.

     The improvement in gross profit was partially offset by approximately $1.5
million of one-time charges related to the Galaxy IV satellite failure. On May
19, 1998, services on the Galaxy IV satellite were permanently lost when the
satellite ceased communicating to uplink stations throughout the United States.


     SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 3.2% from $33.3 million in 1997 to $34.3
million in 1998. As a percentage of total revenues, selling, general and
administrative expense decreased from 36.5% in 1997 to 34.4% in 1998. Selling
and marketing expenses increased 3.0% from $13.8 million in 1997 to $14.2
million in 1998, principally due to an increase in commissions paid as a result
of increased levels of sales of business products. General and administrative
costs increased 3.3% from $19.5 million in 1997 to $20.1 million in 1998,
primarily due to transaction costs related to the merger.

     NON-CASH INCENTIVE COMPENSATION. Non-cash incentive compensation increased
from $0.2 million in 1997 to $2.2 million in 1998. This increase is primarily
due to the meeting of performance criteria for options issued combined with the
increase in value of Old Muzak.

     DEPRECIATION EXPENSE. Depreciation expense decreased 8.6% from $10.7
million in 1997 to $9.7 million in 1998, principally as a result of a reduction
of depreciation expense for assets that were fully depreciated in 1997 related
to the acquisition of Old Muzak in September 1992.

     AMORTIZATION EXPENSE. Amortization expense increased 18.1% from $10.0
million in 1997 to $11.8 million in 1998. The increase in amortization expense
was due to an increase in intangibles related to the increased investment in
the expanded customer base and acquisitions of competitor's business music
contracts in 1997 and 1998.


                                       13
<PAGE>

     INTEREST EXPENSE. Total interest expense increased 4.4% from $10.8 million
in 1997 to $11.2 million in 1998. The increase in interest expense in 1998
compared to 1997 is related to the increase in the average outstanding debt
during the year. Old Muzak's total interest-bearing debt increased from $101.0
million to $118.4 million at December 31, 1997 and 1998, respectively.


LIQUIDITY AND CAPITAL RESOURCES

     The Company had cash and cash equivalents totaling $2.3 million and $1.3
million at December 31, 1999 and 1998, respectively. The Company had $10.0
million of borrowing availability under its credit agreements as of December
31, 1999. Availability under the revolving credit facility has been reduced by
outstanding letters of credit of $0.3 million.


SOURCES AND USES OF FUNDS

     The Company's principal sources of funds are cash generated from
continuing operations, borrowings under the Senior Credit Facility, Floating
Rate Notes and proceeds from equity contributions. The Company's strategic plan
is to pursue opportunities to acquire music contract portfolios of competitors
and to review acquisitions of independent franchisees if they become available.
However, the Company may require additional debt or equity financing to
complete additional acquisitions. In February 2000, the Company received equity
contributions totaling $10.6 million from its members. The proceeds were used
to pay down the revolving loan and to fund acquisitions. Net cash used by
continuing operating activities of the Company was $2.3 million for 1999.

     The Company's principal uses of funds from operating activities and
borrowings for the next several years are expected to fund acquisitions,
interest and principal payments on its indebtedness, net working capital
increases and capital expenditures. At December 31, 1999, the Company has total
outstanding indebtedness of $382.3 million (excluding approximately $0.3
million of outstanding letters of credit) at an average interest rate of 11.61%.
Of the total outstanding indebtedness, $349.5 million relates to the Senior
Credit Facility, the Senior Notes, and the Senior Discount Notes.

     Proceeds from the Senior Credit Facility, the Senior Notes, and the Senior
Discount Notes were used to pay merger consideration consisting of $125.5
million in cash to the partners of Old Muzak, approximately $114.9. million
consideration in the tender offer and consent solicitation for the 10% Senior
Notes due 2003 of Old Muzak together with accrued interest, $15.9 million for
debt repayment of Old Muzak obligations, approximately $42.4 million of
borrowings by Audio Communications Network under ABRY Broadcast Partners III
subordinated note, merger consideration for Capstar Broadcasting Corporation,
and to pay fees and expenses in connection with the foregoing.


CAPITAL EXPENDITURES

     The Company's business generally requires capital for the installation of
equipment for new business music clients. The Company currently anticipates
that its capital expenditures for fiscal 2000 will be in the range of $ 24.0
million to $ 29.0 million, a portion of which may be financed through leasing.
As of December 31, 1999, the Company had approximately $5.2 million in
outstanding capital expenditure commitments. Of the total, approximately $3.8
million in commitments are related to the construction of the Company's new
headquarters facility in Fort Mill, South Carolina. In addition, during 2000,
the Company will continue to pursue a business strategy that includes selective
acquisitions.


SENIOR CREDIT FACILITY

     In March 1999, the Company entered into a new senior credit facility
("Senior Credit Facility") consisting of: (i) a term loan facility in the
amount of $30.0 million payable in semi-annual installments until final
maturity on December 31, 2005 ("Term Loan A"); (ii) a term loan facility in the
amount of $105.0 million payable in semi-annual installments until final
maturity on December 31, 2006 ("Term Loan B")(together with Term Loan A, the
"Term Loans"); and (iii) a revolving loan (the "Revolving Loan") in an
aggregate principal amount of up to $35.0 million terminating on December 31,
2005. In July 1999, the Company amended the Senior Credit Facility which
increased the principal amount of Term Loan B by $30.0 million to $135.0
million. In October 1999, the Company amended the Senior Credit Facility to
enable a related party to make a subordinated loan to the Company in the
aggregate principal amount of $20.0 million and to permit the Company to issue
additional senior subordinated notes and the Company to issue preferred stock if
certain covenants are met by the Company.

     The Senior Credit Facility, which is guaranteed by the Company, and certain
of its domestic subsidiaries, contains restrictive covenants including
maintenance of interest and leverage ratios and various other restrictive
covenants


                                       14
<PAGE>

which are customary for such facilities. In addition, the Company is generally
prohibited from incurring additional indebtedness, incurring liens, paying
dividends or making other restricted payments, consummating asset sales,
entering into transactions with affiliates, merging or consolidating with any
other person or selling assigning, transferring, leasing, conveying, or
otherwise disposing of assets. These conditions were satisfied as of December
31, 1999. Such limitations, together with the Company's highly leveraged nature
could limit the Company's corporate and operating activities in the future,
including the implementation of future acquisitions.


FLOATING RATE NOTES

     In January 2000, the Company entered into an indenture for up to $50.0
million Senior Subordinated Floating Rate Notes (the "Floating Rate Notes").
The Floating Rate Notes will be available for drawdowns until July 31, 2000.
Commitments on all amounts undrawn under the Floating Rate Notes by July 31,
2000 will expire and will be ineligible for future drawdowns. The Floating Rate
Notes may be redeemed at 100% if redeemed before July 31, 2000 and at 101.50%
if redeemed August 1, 2000 through October 31, 2000. If the Company does not
redeem the Floating Rate Notes by November 1, 2000, the Floating Rate Notes
will automatically convert into fixed-rate permanent notes due March 2009. As
of March 29, 2000, $25.0 million of the Floating Rate Notes were outstanding.
Proceeds from the Floating Facility will be used to fund acquisitions.


SENIOR SUBORDINATED NOTES

     On March 18, 1999, the Company together with its wholly owned subsidiary,
Muzak Finance Corp., co-issued $115.0 million in principal amount of Senior
Subordinated Notes ("Senior Notes") which mature on March 15, 2009. Interest is
payable semi-annually, in arrears, on March 15 and September 15 of each year,
commencing on September 15, 1999.

     The Senior Notes are general unsecured obligations of the Company and Muzak
Finance and are subordinated in right of payment to all existing and future
Senior Indebtedness of the Company and Muzak Finance. The Senior Notes are
guaranteed by the Company, MLP Environmental Music, LLC, Business Sound, Inc.,
BI Acquisition LLC, Audio Environments, Inc., Background Music Broadcasters,
Inc., and Muzak Capital Corporation. The indenture governing the Senior Notes
generally prohibits the Company from making certain payments such as dividends
and distributions of their capital stock; repurchases or redemptions of their
capital stock, and investments (other than permitted investments) unless certain
conditions are met by the Company.

     Before March 15, 2002, the issuers may redeem up to 35% of the aggregate
principal amount of the Notes originally issued under the indenture at a
redemption price of 109.875% of the aggregate principal amount so redeemed,
plus accrued and unpaid interest to the redemption date, with the net proceeds
of one or more equity offerings if certain conditions are met. After March 15,
2004, the issuers may redeem all or part of the Senior Notes at a redemption
price equal to 104.938% of the principal amount, which redemption price
declines to 100% of the principal amount in 2007.


SENIOR DISCOUNT NOTES

     On March 18, 1999, the Company together with its wholly owned subsidiary
Muzak Holdings Finance Corp., co-issued $75.0 million in principal amount at
maturity or $39.9 million in accreted value on the issue date, of 13% Senior
Discount Notes (the "Senior Discount Notes") due 2010. Cash interest on the
Senior Discount Notes does not accrue and is not payable prior to March 15,
2004. The Senior Discount Notes were issued at a substantial discount from
their principal amount at maturity. Until March 15, 2004, the Senior Discount
Notes will accrete in value such that the accreted value on March 15, 2004 will
equal the principal amount at maturity of the Senior Discount Notes. From and
after March 15, 2004, interest on the Senior Discount Notes will accrue at a
rate of 13% per annum. Interest will be payable semi-annually in arrears on
each March 15 and September 15, commencing September 15, 2004, to holders of
record of the Senior Discount Notes at the close of business on the immediately
preceding March 1 and September 1.

     The Senior Discount Notes are general unsecured obligations of the Company
and Muzak Holdings Finance Corp and effectively subordinated in right of payment
to all existing and future Senior Indebtedness of the Company and Muzak Finance
Corp. Muzak Holdings Finance Corp. has no operations and substantially no
assets. Accordingly, the Company is dependent upon the distribution of the
earnings of its subsidiaries to service its debt obligations. The indenture
governing the Senior Discount Notes generally prohibits the Company and its
restricted subsidiaries from making certain payments such as dividends and
distributions of their capital stock; repurchases or redemptions of their
capital stock, and investments (other than permitted investments) unless certain
conditions are met by the Company and its restricted subsidiaries.


                                       15
<PAGE>

     Before March 15, 2002, the issuers may redeem up to 35% of the aggregate
principal amount of the Senior Discount Notes originally issued under the
indenture at a redemption price of 113% of the aggregate principal amount so
redeemed, plus accrued and unpaid interest to the redemption date, with the net
proceeds of one or more equity offerings if certain conditions are met. After
March 15, 2004, the issuers may redeem all or part of the Senior Discount Notes
at a redemption price equal to 106.5% of the principal amount which redemption
price declines to 100% of the principal amount in 2007.


RELATED PARTY DEBT

     From July 1, 1999 through November 24, 1999, the Company borrowed an
aggregate amount of $30.0 million from MEM Holdings LLC in the form of Junior
Subordinated Unsecured Notes (the "ABRY Notes"). The ABRY Notes mature on June
30, 2007, at which time principal and accrued interest are due. Interest
accrues at 15% per annum; any accrued interest not paid as of March 31, June
30, September 30 or December 31 will bear interest at 15% per annum until such
interest is paid or extinguished. The ABRY Notes are junior and subordinate to
payments for the Senior Credit Facility and the Senior Notes. Proceeds from the
ABRY Notes were used to fund operations and acquisitions.


INTEREST RATE EXPOSURE

     Indebtedness under the Term Loan A and the revolving loans bears interest
at a per annum rate equal to the Company's choice of (i) the Alternate Base
Rate (which is the highest of prime rate and the Federal Funds Rate plus .5%)
plus a margin ranging from 1.00% to 2.00% or (ii) the offered rates for
Eurodollar deposits ("LIBOR") of one, two, three, or six months, as selected by
the Company, plus a margin ranging from 2.0% to 3.0%. Margins, which are
subject to adjustment based on the changes in the Company's ratio of
consolidated total debt to EBITDA (i.e., earnings before interest, taxes,
interest, depreciation, amortization and other non cash charges) were 2.0% in
the case of Alternate Base Rate and 3.0% in the case of LIBOR as of December
31, 1999. Indebtedness under the Term Loan B bears interest at a per annum rate
equal to the Company's choice of (i) the Alternate Base Rate (as described
above) plus a margin of 2.5% or (ii) LIBOR of one, two, three, or six months,
as selected by the Company plus a margin of 3.5%. Commitment fees range from
 .375% to .625%.

     Indebtedness under the Floating Rate Notes bears interest at a per annum
rate equal to (i) three month LIBOR plus a margin of 5.0% until July 31, 2000
(ii) at three month LIBOR plus a margin of 7.5% for the period beginning August
1, 2000 through October 31, 2000 and (iii) for the period from November 1, 2000
through maturity, at a fixed rate based on the greater of (a) three month LIBOR
plus 7.5% and (b) the yield on the Company's Senior Notes plus 2.5%.

     Interest on the Senior Notes accrues at a rate of 9.875% per annum. Until
March 15, 2004, the Senior Discount Notes will accrete in value such that the
accreted value on March 15, 2004 will equal the principal amount at maturity of
the Senior Discount Notes. From and after March 15, 2004, interest on the
Senior Discount Notes will accrue at a rate of 13% per annum.

     Cash interest paid was $14.1 million, $2 thousand, $2.9 million, and $2.2
million, for the fiscal year ended December 31, 1999, the period from October
7, 1998 through December 31, 1998, the period from January 1, 1998 through
October 6, 1998, and for the fiscal year ended December 31, 1997, respectively.


     Due to the variable interest rates under the Senior Credit Facility, the
Company is sensitive to changes in interest rates. Accordingly, during April
1999, the Company entered into a four year interest rate swap agreement in
which the Company effectively exchanged $100.0 million of floating rate debt at
three month LIBOR for 5.59% fixed rate debt. The Company terminated this
agreement on January 28, 2000 and received approximately $4.4 million for this
agreement. On January 28, 2000, the Company entered into a new interest rate
swap agreement in which the Company effectively exchanged $100.0 million of
floating rate debt at three month Libor for 7.042% fixed rate debt. The
interest rate swap agreement terminates on April 19, 2002. Based on amounts
outstanding at December 31, 1999, a .5% increase in each of LIBOR and the
Alternate Base Rate (6.19% and 8.5% respectively, at December 31, 1999) would
impact interest costs by approximately $0.9 million annually on the Senior
Credit Facility.


DEBT MATURITIES

     The current maturities of long-term debt primarily consist of the current
portion of the Senior Credit Facility and other miscellaneous debt. The
maturities of long-term debt of the Company's operations during 2000, 2001,
2002, 2003, and 2004 are $4.2 million, $5.2 million, $6.7 million, $7.8
million, $26.3 million, respectively. The Senior Notes mature in March 2009. In
addition, the Senior Credit Facility provides for mandatory prepayments with
net cash proceeds of certain asset sales, net cash proceeds of permitted debt
issuances, net cash proceeds from insurance recovery and condemnation events,
and beginning December 31, 2000 the Senior Credit Facility requires annual
excess cash repayments. The indentures governing the Senior Notes and the
Senior Discount Notes provide that in the event of certain asset dispositions,
the Company


                                       16
<PAGE>

must apply net proceeds first to repay Senior Indebtedness. To the extent the
net proceeds have not been applied within 360 days from the asset disposition to
an investment in capital expenditures or other long term tangible assets used in
the business, and to the extent the remaining net proceeds exceed $10.0 million,
the Company must make an offer to purchase outstanding Senior Notes at 100% of
their principal amount plus accrued interest. To the extent there are excess
funds after the purchase of the Senior Notes, the Company must make an offer to
purchase outstanding Senior Discount Notes at 100% of the accreted value. The
Company must also make an offer to purchase outstanding Senior Notes and the
Senior Discount Notes at 101% of their principal amount plus accrued and unpaid
interest if a Change in Control of the Company occurs. Subject to compliance
with the Senior Credit facility, the Floating Rate Notes will be mandatory
redeemable with the proceeds of any securities issuances or incurrences of
indebtedness at any time on or prior to October 31, 2000. If the Company does
not redeem the Floating Rate Notes by November 1, 2000, the Floating Rate Notes
will automatically convert into fixed-rate permanent notes due March 15, 2009.


IMPACT OF YEAR 2000 COMPLIANCE

     The Company's program to address the Year 2000 issue consisted of (i)
assessing the state of Year 2000 readiness of its systems and third parties
upon which it relies (ii) replacing the primary computer system at headquarters
and owned operations, (iii) testing these systems, and (iv) contingency
planning. The Company did not experience any significant disruption as a result
of the Year 2000 issue.

     Costs related to the Year 2000 issue were approximately $1.0 million and
were funded through operating cash flows.

     The Company completed its assessment of its Year 2000 risks related to
significant relationships with its critical third party suppliers and
customers. Despite these efforts, the Company can provide no assurance that all
third parties compliance plans were successfully completed in a timely manner,
although it is not aware of any problems which would significantly impact its
operations.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE EXPOSURE

     The Company's exposure to market risk for changes in interest rates
relates primarily to the Company's long-term debt obligations. The interest
rate exposure for the Company's variable rate debt obligations is currently
indexed to LIBOR of one, two, or three months as selected by the Company, or
the Alternate Base Rate. The Company uses interest rate swap agreements to
modify its exposure to interest rate movements and to reduce borrowing rates.

     The table below provides information about the Company's debt obligations
and interest rate protection agreement. For debt obligations, the table
presents principal cash flows and related weighted average interest rates by
expected maturity dates. For interest rate protection agreements, the table
presents notional amounts and weighted average interest rates by expected
(contractual) maturity dates. Weighted average variable interest rates are
based on implied LIBOR in the yield curve at the reporting date. The principal
cash flows are in thousands.

To the Board of Directors
of Muzak Holdings LLC:

In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) on page 25 related to Muzak Holdings LLC present
fairly, in all material respects, the financial position of Muzak Holdings LLC
and its subsidiaries (the "Company"), formally known as ACN Holdings, LLC, at
December 31, 1999 and 1998, and the results of their operations and their cash
flows for the year ended December 31, 1999 and for the period from October 7,
1998 to December 31, 1998, in conformity with accounting principles generally
accepted in the United States. 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 auditing standards generally accepted in the
United States, 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.

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

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.

material respects, the results of operations and cash flows of the Predecessor
Company for the year ended December 31, 1997 in conformity with generally

Muzak LLC, a wholly owned subsidiary of the Company, owns and operates
franchisees. Muzak LLC began its operations on October 7, 1998 with the
acquisition of the independent franchisees in the Baltimore, Charlotte,
Hillsborough, Kansas City, St. Louis, Jacksonville, Phoenix, and Fresno areas
from Audio Communications Network, Inc. (the "Predecessor Company"). On March
18, 1999, Muzak Limited Partnership ("Old Muzak") merged with and into Audio
Communications Network, LLC ("ACN"). At the time of the merger, ACN changed its
name to Muzak LLC.

     As of December 31, 1999, ABRY Partners, LLC. and its respective affiliates
collectively own approximately 68% of the beneficial interests in the Company's
voting interests.

     The Company derives the majority of its revenues from the sale of business
music products. The core porduct is Audio Architecture and its two
complementary products are Audio Marketing and Video Imaging. These revenues
are generated by clients, who pay monthly subscription fees under noncancelable
five year contracts.

     The Company also derives revenues from the sale and lease of audio
system-related products, principally sound systems and intercoms, to business
music clients and other clients. In addition, the Company sells electronic
equipment, such as proprietary tape playback equipment and other audio and
video equipment to franchisees to support the sale of business music services.
Installation, service and repair revenues consist principally of revenues from
the installation of sound systems and other equipment that is not expressly
part of a business music contract, such as paging, security and drive-through
systems. These revenues also include revenue from the installation, service and
repair of equipment installed under a business music contract. Music contract
installation revenues are deferred and recognized over the term of the
respective contracts.

     BASIS OF PRESENTATION -- The consolidated financial statements include the
accounts of the Company and its subsidiaries; Muzak LLC, Muzak Holdings Finance
Corporation, Muzak Capital Corporation, Muzak Finance Corporation, Business
Sound Inc., Electro Systems Corporation, BI Acquisition LLC, MLP Environmental
Music, LLC, Audio Environments, Inc, and Background Music Broadcasters, Inc. All
significant intercompany items have been eliminated in consolidation. Certain
prior year items have been reclassified to conform with the fiscal 1999
presentation.

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

     CASH AND CASH EQUIVALENTS -- Cash and cash equivalents include all cash
balances and highly liquid investments with an original maturity of three
months or less.

     INVENTORIES -- Inventories consist primarily of electronic equipment and
are valued at the lower of cost or market, but not in excess of net realizable
value. Cost is determined on the first-in, first-out basis.

     PROPERTY AND EQUIPMENT -- Property and equipment are stated at cost.
Depreciation is computed on a straight-line basis over the estimated useful
lives of the assets, ranging from 3 to 30 years. Sound and music equipment
installed at customer premises under contracts to provide music programming
services is transferred from inventory to property and equipment at cost plus
an allocation of installation costs and is amortized over 5 years. Impairment
losses are recognized if recorded values exceed undiscounted future cash flows,
by reducing them to estimated fair value. No impairment losses were recognized
by the Company or the Predecessor Company for the periods presented.

     INTANGIBLE ASSETS -- Goodwill, the excess of the purchase price over the
fair value of net assets of businesses acquired, is amortized over twenty years
using the straight-line method. Income producing contracts are amortized using
the straight-line method over periods ranging from 8-14 years. Management
evaluates the recoverability of intangibles by comparing

recorded values to the undiscounted future cash flows that can be generated by
such assets. Impairment losses are recognized if recorded values exceed
undiscounted future cash flows, by reducing them to estimated fair value. No
impairment losses were recognized by the Company and the Predecessor Company for
the periods presented.

     INCOME TAXES -- The Company is a Limited Liability Company that is treated
as a partnership for income tax purposes. No provision for income taxes is
required by the Company as its income and expenses are taxable to or deductible
by its members. The Company's corporate subsidiaries are subject to income
taxes and account for deferred income taxes under the liability method which
requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of temporary differences between the carrying
amounts and the tax basis of assets and liabilities.

     REVENUE RECOGNITION -- Revenues from music services are recognized on a
straight-line basis over the term of the customer contracts in the period
services are provided. Revenues for equipment sales and related installation
are recognized upon delivery or installation. Contracts are typically for a
five-year non-cancelable period with renewal options for an additional five
years. Fees received for services to franchisees are recognized as revenues in
the month services are provided.

     SUBSCRIBER ACQUISITION COSTS -- Subscriber acquisition costs are direct
sales commissions incurred in connection with acquiring new subscribers, which
are amortized as a component of selling, general, and administrative expenses
over the life of the customer contract or five years, whichever is shorter, on
a straight-line basis. If a customer contract terminates early, the unamortized
subscriber acquisition costs is typically recovered from the salesperson.
Subscriber acquisition costs are included in deferred charges and other assets,
net.

     ADVANCE BILLINGS -- The Company invoices certain customers in advance for
contracted music and other business services. Amounts invoiced in advance of
the service period are deferred when invoiced and recognized as revenue in the
period earned.

     CONCENTRATION OF CREDIT RISK -- Concentrations of credit risk with respect
to trade accounts receivable are limited as the Company sells its products to
customers in diviersified industries thorughout the United States. The Company
performs ongoing credit evaluations of its customers' financial condition and
maintains allowances for potential credit losses. Actual losses have been
within management's expectations and estimates.


2. ACQUISITIONS

     On October 7, 1998, the Company acquired certain assets and liabilities of
the Predecessor Company for $66.8 million. The acquisition was accounted for
using the purchase method of accounting. Accordingly, the consideration paid was
allocated based on the estimated fair market value of the net assets acquired.
The excess of the consideration paid over the estimated fair market value of the
net assets acquired approximated $17.0 million and is being amortized using the
straight-line method over 20 years.

     In order to complete the acquisition of the Predecessor Company, the
Company received a $8.4 million capital contribution and issued notes payable of
$40.8 million to a Member (see Note 6).

     As discussed in Note 1, on March 18, 1999 Old Muzak merged with and into
ACN. Under the terms of the agreement, the Company paid total consideration of
$274.2 million, which is comprised of the following: $125.5 million cash
consideration, $114.9 million consideration in the tender offer and consent
solicitation for the 10% Senior Notes due 2003 of Old Muzak, $15.9 million for
debt repayment of Old Muzak outstanding obligations and assumed $17.9 million
of other obligations. In addition, at the time of the merger, the Company
repaid $41.7 million borrowed from ABRY Broadcast Partners by ACN in October
1998 in connection with the acquisition of the Company's independent
franchisees from the Predecessor Company and converted $0.7 million into voting
units of the Company.

     In 1999, prior to the merger, the Company made the following acquisitions:

2. ACQUISITIONS -- (CONTINUED)

     The results of operations of the acquired companies are included in the
Company's consolidated statement of operations for the periods in which they
were owned by the Company.

     The acquisitions were accounted for under the purchase method of
accounting. Accordingly, the consideration was allocated to the net assets
acquired based on the fair market values at the date of acquisition as
determined through the use of an independent appraisal. The excess of purchase
price for each acquisition over the estimated fair value of the tangible and
identifiable intangible assets acquired approximated $127.9 million and is
being amortized over a period of twenty years on a straight-line basis.

     The following presents the unaudited pro forma results assuming that the
acquisitions discussed above and financings (see Note 6) had occurred as of the
beginning of fiscal 1999 and 1998. These pro forma results are not necessarily
indicative of the results that will occur in future periods (in thousands).

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

6. DEBT -- (CONTINUED)

SENIOR CREDIT FACILITY

     In March 1999, the Company entered into a new senior credit facility
("Senior Credit Facility") consisting of: (i) a term loan facility in the amount
of $30.0 million payable in semi-annual installments until final maturity on
December 31, 2005 ("Term Loan A") ; (ii) a term loan facility in the amount of
$105.0 million payable in semi-annual installments until final maturity on
December 31, 2006 ("Term Loan B")(together with Term Loan A , the "Term Loans");
and (iii) a revolving loan (the "Revolving Loan") in an aggregate principal
amount of up to $35.0 million terminating on December 31, 2005. In July 1999,
the Company amended the Senior Credit Facility which increased the principal
amount of the Term Loan B by $30.0 million to $135.0 million. In October 1999,
the Company amended the Senior Credit Facility to enable a related party to make
a subordinated loan to the Company in the aggregate principal amount of $20.0
million and to permit the Company to issue additional senior subordinated notes
and to issue preferred stock if certain covenants are met by the Company.

     The Senior Credit Facility, which is guaranteed by the Company and
certain of its domestic subsidiaries, contains restrictive covenants including
maintenance of interest and leverage ratios and various other restrictive
covenants which are customary for such facilities. In addition, the Company is
generally prohibited from incurring additional indebtedness, incurring liens,
paying dividends or making other restricted payments, consummating asset sales,
entering into transactions with affiliates, merging or consolidating with any
other person or selling assigning, transferring, leasing, conveying, or
otherwise disposing of assets. These conditions were satisfied as of December
31, 1999.

     Indebtedness under the Term Loan A and the Revolving Loans bear interest
at a per annum rate equal to the Company's choice of (i) the Alternate Base
Rate (which is the highest of prime rate and the Federal Funds Rate plus .5%)
plus a margin ranging from 1.00% to 2.00% or (ii) the offered rates for
Eurodollar deposits ("LIBOR") of one, two, three, or six months, as selected by
the Company, plus a margin ranging from 2.0%to 3.0%. Margins, which are subject
to adjustment based on the changes in the Company's ratio of consolidated total
debt to EBITDA (i.e., earnings before interest, taxes, interest, depreciation,
amortization and other non cash charges) were 2.0% in the case of Alternate
Base Rate and 3.0% in the case of LIBOR as of December 31, 1999. Indebtedness
under the Term Loan B bears interest at a per annum rate equal to the Company's
choice of (i) the Alternate Base Rate (as described above) plus a margin of
2.5% or (ii) LIBOR of one, two, three, or six months, as selected by the
Company plus a margin of 3.5%. The weighted average rate of interest on the
Senior Credit Facility at December 31, 1999 was 9.01%.


SENIOR NOTES

     On March 18, 1999, the Company together with its wholly owned subsidiary,
Muzak Finance Corp., co-issued $115.0 million in principal amount of 9 7/8%
Senior Subordinated Notes ("Senior Notes") which mature on March 15, 2009.
Interest is payable semi-annually, in arrears, on March 15 and September 15 of
each year. The Senior Notes are general unsecured obligations of the Company
and Muzak Finance and are subordinated in right of payment to all existing and
future Senior Indebtedness of the Company and Muzak Finance. The Senior Notes
are guaranteed by the Company, MLP Environmental Music, LLC, Business Sound,
Inc., BI Acquisition LLC, Audio Environments, Inc., Background Music
Broadcasters, Inc., and Muzak Capital Corporation. The indenture governing the
Senior Notes prohibits the Company from making certain payments such as
dividends and distributions of their capital stock; repurchases or redemptions
of their capital stock, and investments (other than permitted investments)
unless certain conditions are met by the Company. Before March 15, 2002, the
issuers may redeem up to 35% of the aggregate principal amount of the Notes
originally issued under the indenture at a redemption price of 109.875% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest to the
redemption date, with the net proceeds of one or more equity offerings if
certain conditions are met. After March 15, 2004, the issuers may redeem all or
part of the Notes at a redemption price equal to 104.938% of the principal
which redemption price declines to 100% of the principal amount in 2007.


SENIOR DISCOUNT NOTES

On March 18, 1999, the Company together with its wholly owned subsidiary Muzak
Holdings Finance Corp., co-issued $75.0 million in principal amount at maturity,
or $39.9 million in accreted value on the issue date, of 13% Senior Discounted
Notes (the "Senior Discount Notes") due March 2010. Cash interest on the Senior
Discount Notes does not accrue and is not payable prior to March 15, 2004. The
Discounted Notes were issued at a substantial discount from their principal
amount at maturity. Until March 15, 2004, the Discounted Notes will accrete in
value such that the accreted value on March 15, 2004 will equal the principal
amount at maturity of the Senior Discount Notes. From and after March 15, 2004,
interest on the Senior Discount Notes will accrue at a rate of 13% per annum.
Interest will be payable semi-annually in arrears on each March 15 and September
15, commencing September 15, 2004, to holders of record of the Senior Discount
Notes at the close of business on the immediately preceding March 1 and
September 1.

6. DEBT -- (CONTINUED)

RELATED PARTY NOTES

     From July 1, 1999 through November 24, 1999, the Company borrowed an
aggregate amount of $30.0 million, from MEM Holdings LLC in the form of Junior
Subordinated Unsecured Notes (the "ABRY Notes"). MEM Holdings is a company that
owns 68% of the voting interests in the Company. ABRY Broadcast Partners III and
ABRY Broadcast Partners II are the beneficial owners of MEM Holdings.

     The ABRY Notes mature on June 30, 2007, at which time principal and accrued
interest are due. Interest accrues at 15% per annum; any accrued interest not
paid as of March 31, June 30, September 30 or December 31 will bear interest at
15% per annum until such interest is paid or extinguished. The ABRY Notes are
junior and subordinate to payments for the Senior Credit Facility, and the
Senior Notes. At any time, all of the ABRY Notes, with the exception of the $3.0
million note may be converted into class A units of the Company. If the ABRY
Notes with the exception of the $3.0 million note, have not been repaid in full
as of May, 2001, the ABRY Notes will automatically be converted into class A
units. Proceeds from the ABRY Notes were used to fund operations and
acquisitions.

     In order to complete the acquisition of the Predecessor Company, the
Company issued Notes payable to a member for $40.8 million in 1998. The Company
repaid $41.7 million outstanding under this note at the time of the merger and
converted $0.7 million into Class A units of the Company.


OTHER DEBT

     In connection with the purchase of ElectroSystems on February 24, 1999,
the Company assumed several promissory notes, totaling $2.4 million as of the
acquisition date. All of the notes, with the exception of one, bear interest at
9.887% and mature in November 2016. The Company is required to make interest
only payments on a monthly basis through October 2006, and principal and
interest payments for the remainder of the term. The Note terms are the same
for all but one of the notes. This note bears interest at 8% with principal and
interest payments due monthly until maturity in October 2006.

     See Note 15 for a description of additional debt incurred by the Company
after December 31, 1999.


ANNUAL MATURITIES

     Annual maturities of long-term debt obligations are as follows (in
thousands):


<TABLE>
<S>                    <C>
  2000 ...............  $  4,197

  2003 ...............     7,761
  2004 ...............    26,344
  Thereafter .........   277,165
</TABLE>

     Total interest paid by the Company on all indebtedness was $14.1 million,
$2.0 thousand, $2.9 million, and $2.2 million for the year ended December 31,
1999, the period from October 7, 1998 through December 31, 1998, for the period
from January 1, 1998 through October 6, 1998 and the year ended December 31,
1997, respectively.


INTEREST RATE PROTECTION PROGRAMS

     During April 1999, the Company entered into a four year interest rate swap
agreement in which the Company effectively exchanged $100.0 million of floating
rate debt at three month LIBOR for 5.59% fixed rate debt. This agreement is
designated as a hedge of interest rates, and the differential to be paid or
received on the swap is accrued as an adjustment to interest expense as
interest rates change. The Company is exposed to credit loss in the event of
nonperformance by the other party to the swap agreement. However, the Company
does not anticipate nonperformance by the counterparty. The effect of this
interest rate protection agreement on the operating results of the Company was
to increase interest expense by $67 thousand in fiscal 1999. The Company
terminated this agreement on January 28, 2000 and received approximately $4.4
million for this agreement. The proceeds will be recorded an as adjustment to
interest expense.

6. DEBT -- (CONTINUED)

     On January 28, 2000, the Company entered into a new interest rate swap
agreement in which the Company effectively exchanged $100.0 million of floating
rate debt at three month LIBOR for 7.042% fixed rate debt. The interest rate
swap agreement terminates on April 19, 2002. Payments received, if any, as a
result of this agreement are accrued as an adjustment to interest expense.


FAIR VALUE OF FINANCIAL INSTRUMENTS

     The estimated fair values of the Company's debt as of December 31, 1999 and
December 31, 1998 were $378.4 million and $42.7 million, respectively. The fair
value of the Senior Notes and the Senior Discount Notes are based upon quoted
market price. The fair value of the other long-term debt of the Company
approximates the carrying value.

     The fair value of the interest rate swap agreement was approximately $4.4
million as of December 31, 1999. The fair values of interest rate swaps are
obtained from dealer quotes which represents the estimated amount the Company
would receive or pay to terminate agreements taking into consideration current
interest rates and creditworthiness of the counterparties.


7. LEASE COMMITMENTS

     The Company is the lessee under various long-term operating and capital
leases for machinery, equipment, buildings, and vehicles for periods ranging
from 2 years to 10 years. The Company has also entered into various agreements
to lease transponders to transmit music programs via direct broadcast
satellite. The majority of these leases contain renewal provisions.

8. EMPLOYEE BENEFIT PLANS

     During 1999, the Company maintained two defined contribution plans.
Substantially all employees are covered under a plan whereby eligible employees
may contribute up to 14% of their compensation per year, subject to certain tax
law restrictions. The Company has the option to make a matching contribution up
to a maximum of 100% of the first 3% and 50% of the next 3%, up to 6% of the
total base salary contributed by the employee each year. Participants are
immediately vested in their contributions as well as the employer's
contributions. Certain other employees are covered under a plan whereby
employees may contribute up to 15% of pre-tax pay and employer contributions
are discretionary. Participants are immediately vested in their contributions
and become fully vested in employer contributions after the third year of
service with the Company.

     Plan expense was $0.8 million, $55 thousand, $23 thousand, and $32
thousand for the year ended December 31, 1999, for the period from October 7,

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

9. MEMBERS' INTEREST
     The Company has authorized two classes of equity units: class A units
("Class A Units") and class B units ("Class B Units")(collectively, the
"Units"). Each class of units represents a fractional part of the membership
interests of the Company.


VOTING UNITS

     Each class A unit is entitled to voting rights equal to the percentage
such unit represents of the aggregate number of outstanding class A units. Each
class A unit accrues a preferred return (the "ACN Holdings Preferred Return")
annually on the original issue price ("the "Capital Value") of each voting unit
at a rate of 15% per annum. The Company can not pay distributions, other than
tax distributions, in respect of other classes of securities, including
distributions made in connection with a liquidation, until the Capital Value
and accrued ACN Holdings Preferred Return in respect of each voting unit is
paid to each holder (such distributions being the "Priority Distributions"). In
addition to these Priority Distributions, each holder of these voting units is
also entitled to participate in distributions payable to the residual common
equity interests of the Company (the "Last Priority Distributions").


NON VOTING UNITS

     The class B units are non-voting equity interests in the Company which are
divided into four subclasses, Class B-1 units, Class B-2 units, Class B-3
units, and Class B-4 units. Each holder of class B units is entitled to
participate in Last Priority Distributions, if any, provided that Priority
Distributions on all voting interests have been paid in full. The Company is
authorized to issue class B-5 units, however no B-5 units are outstanding as of
December 31, 1999. The class B-1 units, B-2 units, and B-3 units have a vesting
period of five years, and the class B-4 units vest immediately upon issuance.
Upon a change in control, as defined, all of these units become fully vested
and exercisable. As of December 31, 1999 and 1998, the Company had 2,410 and
804 B-1 units outstanding, respectively. As of December 31, 1999 and 1998, the
Company had 2,429 and 806 B-2 units outstanding, respectively. As of December
31, 1999 and 1998, the Company had 2,441 and 804 B-3 units outstanding,
respectively. As of December 31, 1999, the Company had 3,002 B-4 units
outstanding, with a value of $2.8 million. There were no B-4 units outstanding
as of December 31, 1998.

13. COMMITMENTS AND CONTINGENCIES -- (CONTINUED)

     The Company is involved in various claims and lawsuits arising out of the

upon the Company's consolidated financial statements or liquidity.

     As of December 31, 1999, the Company's operations has approximately $5.2
million in outstanding capital expenditure commitments. The Company, as

                                   ARTICLE 1

                  DEFINITIONS AND INCORPORATION BY REFERENCE

principal amount not to exceed $30 million in the aggregate at any time
outstanding (a) that is owed to ABRY III, ABRY, MEM Holdings, Inc. or any other

(and premium, if any) and interest and other payment obligations in respect of
such Indebtedness shall be subordinate to the prior payment in full of the
Company's Obligations under the Notes such that no payments of principal (or
premium, if any) or interest on or otherwise due in respect of such Indebtedness
may be permitted for so long as any Default or Event of Default shall have
occurred and be continuing, (c) that shall automatically convert into common
equity of Holdings within 18 months of the date of issuance thereof, unless
refinanced, and (d) the terms of which have been determined to be fair and rea-

sonable to the Company as determined in good faith by the Board of Directors of
the Company and evidenced by a Board Resolution delivered to the Trustee.

partnership.

          "ABRY III" means ABRY Broadcast Partners III, L.P., a Delaware limited
partnership.

          "Acquired Indebtedness" means Indebtedness of a Person (including an
Unrestricted Subsidiary) existing at the time such Person becomes a Restricted
Subsidiary or is merged into or consolidated with any other Person or which is
assumed in connection with the acquisition of assets from such Person and, in
each case, whether or not incurred by such Person in connection with, or in
anticipation or contemplation of, such Person becoming a Restricted Subsidiary
or such merger, consolidation or acquisition.

          "Acquisition EBITDA" means, with respect to any Asset Acquisition, (i)
EBITDA attributable to the assets to be acquired in such Asset Acquisition for
the same fiscal quarter utilized in determining "Consolidated Leverage Ratio"

Asset Acquisition and as a result of, in the case of cost reductions, an
established program of cost reductions adopted in good faith by the Board of
Directors of the Company. For purposes of the foregoing, cost reductions and
non-recurring costs and expenses, in each case, shall be calculated on a pro
forma basis as if such cost reductions and non-recurring costs and expenses, in
each case, had been implemented at the beginning of such fiscal quarter. Prior
to the consummation of any transaction requiring the inclusion of Acquisition
EBITDA in the calculation of Consolidated Leverage Ratio, the Company shall
deliver to the Trustee an Officers' Certificate indicating the cost reductions
and non-recurring costs and expenses, in each case, taken into account in
determining Acquisition EBITDA and the assumptions underlying such cost
reductions and non-recurring costs and expenses.

     collection from any Subsidiary of such Person in respect of the obligations
     of such Person under the Guarantee of such Person), excluding Indebtedness

                                   THE NOTES

Section 2.01.  Dating; Incorporation of Form in Indenture.
               ------------------------------------------

          The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A which is incorporated in and made part of
this Indenture.  The Notes may have notations, legends or endorsements required
by law, stock exchange rule or usage.  The Issuers may use "CUSIP" numbers in
issuing the Notes.  The Issuers shall approve the form of the Notes.  Each Note
shall be dated the date of its authentication.

          Unless the applicable Holder requests Notes in the form of physical
certificated Notes in registered form ("Certificated Notes"), which shall be
substantially in the form of Exhibit A, Notes offered and sold in reliance on
Rule 144A or in offshore transactions in reliance on Regulation S shall be
issued initially in the form of permanent Global Notes in registered form,
substantially in the form set forth in Exhibit A ("Global Notes"), deposited
with the Depository, duly executed by the Issuers and authenticated by the
Trustee as hereinafter provided and shall bear the legend set forth on Exhibit
B.  The aggregate principal amount of any Global Note may from time to time be
increased or decreased by adjustments made on the records of the Depository, as
hereinafter provided.

          Notes offered and sold to Qualified Institutional Buyers in reliance
on Rule 144A issued in the form of one or more Global Notes (the "U.S. Global
Note") shall be registered in the name of the Depository or its nominee and
deposited with the Depository, duly executed by the Issuers and authenticated by
the Trustee as hereinafter provided, for credit by the Depository to the
respective accounts of beneficial owners of the Notes represented thereby (or
such other accounts as they may direct).
<PAGE>

                                     -51-

          Notes offered and sold in reliance on Regulation S issued in the form
of Global Notes (the "Regulation S Global Note") shall be registered in the name
of the Depository or its nominee, duly executed by the Issuers and authenticated
by the Trustee as hereinafter provided, for credit by the Depository to the
respective accounts of the beneficial owners of the Notes represented thereby
(or such other accounts as they may direct).

          The Issuers shall cause the U.S. Global Note and the Regulation S
Global Note to have separate CUSIP and ISIN numbers.

Section 2.02.  Execution and Authentication.
               ----------------------------

          The Notes shall be executed on behalf of the Issuers by two Officers
of each of the Issuers or an Officer and the Secretary of each of the Issuers.
Such signature may be either manual or facsimile.  The Issuers' seals may be
impressed, affixed, imprinted or reproduced on the Notes and may be in facsimile
form.

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

          A Note shall not be valid until the Trustee manually signs the
certificate of authentication on the Note.  Such signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

          The Trustee or an authentication agent shall authenticate Notes for
original issue in the aggregate principal amount not to exceed $150,000,000 upon
receipt of an authentication order in the form of an Officers' Certificate;
provided that the aggregate principal amount of Notes on the Issue Date shall
- - --------
not exceed $115,000,000.  The aggregate principal amount of Notes outstanding at
any time may not exceed $150,000,000 except as provided in Section 2.07 hereof.
Upon receipt of an authentication order in the form of an Officers' Certificate,
the Trustee shall authenticate an additional series of Notes
<PAGE>

                                     -52-

for issuance in exchange for all Notes previously issued pursuant to an exchange
offer registered under the Securities Act (a "Registered Exchange") or pursuant
to a Private Exchange (as defined in the Registration Rights Agreement).
Exchange Notes (as defined in the Registration Rights Agreement) may have such
distinctive series designation and "CUSIP" numbers as and such changes in the
form thereof as are specified in the Officers' Certificate referred to in the
preceding sentence. Exchange Notes issued pursuant to a Registered Exchange
shall not bear the Private Placement Legend. The Notes shall be issuable only in
registered form without coupons and only in denominations of $1,000 and integral
multiples thereof.

          The Trustee may appoint an authenticating agent to authenticate Notes.
Any such appointment shall be evidenced by an instrument signed by an authorized
officer of the Trustee, a copy of which shall be furnished to the Issuers.  An
authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  An authenticating agent has the same right as an
Agent to deal with the Issuers or an Affiliate of any Issuer.

Section 2.03.  Registrar and Paying Agent.
               --------------------------

          The Issuers shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar"), an office
or agency located in the Borough of Manhattan, City of New York, State of New
York where Notes may be presented for payment ("Paying Agent") and an office or
agency where notices and demands to or upon the Issuers in respect of the Notes
and this Indenture may be served.  The Registrar shall keep a register of the
Notes and of their transfer and exchange.  The Registrar shall provide the
Issuers a current copy of such register from time to time upon request of the
Issuers.  The Issuers may have one or more co-registrars and one or more
additional paying agents.  None of the Issuers nor any Affiliate of the Issuers
may act as Paying Agent.  The Issuers may change any Paying Agent, Registrar or
co-registrar without notice to any Noteholder.
<PAGE>

                                     -53-

          The Issuers shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture.  The agreement shall
implement the provisions of this Indenture that relate to such Agent.  The
Issuers shall notify the Trustee of the name and address of any such Agent.  If
the Issuers fail to maintain a Registrar or Paying Agent, or agent for service
of notices and demands, or fail to give the foregoing notice, the Trustee shall
act as such.  The Issuers initially appoint the Trustee as Registrar, Paying
Agent and agent for service of notices and demands in connection with the Notes.

Section 2.04.  Paying Agent to Hold Money in Trust.
               -----------------------------------

          The Issuers shall require each Paying Agent other than the Trustee to
agree in writing that each Paying Agent shall hold in trust for the benefit of
the Holders or the Trustee all assets held by the Paying Agent for the payment
of principal of, premium, if any, or interest on Notes (whether such assets have
been distributed to it by the Issuers or any other obligor on the Notes), and
shall notify the Trustee in writing of any Default in making any such payment.
The Issuers at any time may require a Paying Agent to distribute all assets held
by it to the Trustee and account for any assets disbursed and the Trustee may at
any time during the continuance of any payment Default, upon written request to
a Paying Agent, require such Paying Agent to forthwith distribute to the Trustee
all assets so held in trust by such Paying Agent together with a complete
accounting of such sums.  Upon doing so, the Paying Agent shall have no further
liability for such assets.

Section 2.05.  Noteholder Lists.
               ----------------

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Noteholders.  If the Trustee is not the Registrar, the Issuers shall furnish to
the Trustee on or before each March 1 and September 1 in each year, and at such
other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of
Noteholders.
<PAGE>

                                     -54-

Section 2.06.  Transfer and Exchange.
               ---------------------

          When a Note is presented to the Registrar with a request to register
the transfer thereof, the Registrar shall register the transfer as requested if
the requirements of applicable law are met and, when Notes are presented to the
Registrar with a request to exchange them for an equal principal amount of Notes
of other authorized denominations, the Registrar shall make the exchange as
requested; provided that every Note presented or surrendered for registration of
           --------
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Issuers and the Registrar
duly executed by the Holder thereof or his attorney duly authorized in writing.
To permit transfers and exchanges, upon surrender of any Note for registration
of transfer at the office or agency maintained pursuant to Section 2.03 hereof,
the Issuers shall execute and the Trustee shall authenticate Notes at the
Registrar's request.  Any exchange or transfer shall be without charge, except
that the Issuers may require payment by the Holder of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation to a
transfer or exchange, but this provision shall not apply to any exchange
pursuant to Sections 2.09, 3.06 or 8.05 hereof.  The Trustee shall not be
required to register transfers of Notes or to exchange Notes for a period of 15
days before selection of any Notes to be redeemed.  The Trustee shall not be
required to exchange or register transfers of any Notes called or being called
for redemption in whole or in part, except the unredeemed portion of any Note
being redeemed in part.

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

Section 2.07.  Replacement Notes.
               -----------------

          If a mutilated Note is surrendered to the Trustee or if the Holder
presents evidence to the satisfaction of the Issuers and the Trustee that the
Note has been lost, destroyed or wrongfully taken, the Issuers shall issue and
the Trustee shall authenticate a replacement Note.  An indemnity bond may be
required by the Issuers or the Trustee that is sufficient in the judgment of the
Issuers and the Trustee to protect the Issuers, the Trustee or any Agent from
any loss which any of them may suffer if a Note is replaced.  In every case of
destruction, loss or theft, the applicant shall also furnish to the Issuers and
to the Trustee evidence to their satisfaction of the destruction, loss or the
theft of such Note and the ownership thereof.  Each of the Issuers and the
Trustee may charge for its expenses in replacing a Note.  Every replacement Note
is an additional obligation of the Issuers.  In the event any such mutilated,
lost, destroyed or wrongfully taken Note has become due and payable, the Issuers
in their discretion may pay such Note instead of issuing a new Note in
replacement thereof.  The provisions of this Section 2.07 are exclusive and
shall preclude (to the extent lawful) all other rights and remedies with respect
to replacement or payment of mutilated, lost, destroyed or wrongfully taken
Notes.

Section 2.08.  Outstanding Notes.
               -----------------

          Notes outstanding at any time are all Notes authenticated by the
Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.08 as not outstanding.

          If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding until the Issuers and the Trustee receive proof satisfactory to each
of them that the replaced Note is held by a bona fide purchaser.

          If a Paying Agent holds on a Redemption Date or Maturity Date money
sufficient to pay the principal of, premium, if any, and accrued interest on
Notes payable on that date,
<PAGE>

                                     -56-

then on and after that date such Notes cease to be outstanding and interest on
them ceases to accrue.

          Subject to Section 12.06, a Note does not cease to be outstanding
solely because the Issuers or any Affiliate of an Issuer hold the Note.

Section 2.09.  Temporary Notes.
               ---------------

          Until definitive Notes are ready for delivery, the Issuers may prepare
and the Trustee shall authenticate temporary Notes.  Temporary Notes shall be
substantially in the form, and shall carry all rights, of definitive Notes but
may have variations that the Issuers consider appropriate for temporary Notes.
Without unreasonable delay, the Issuers shall prepare and the Trustee shall
authenticate definitive Notes in exchange for temporary Notes presented to it.

Section 2.10.  Cancellation.
               ------------

          The Issuers at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment.  The Trustee
shall cancel and retain or, upon written request of the Issuers, may destroy or
return to the Issuers in accordance with its normal practice, all Notes
surrendered for transfer, exchange, payment or cancellation and if such Notes
are destroyed, deliver a certificate of destruction to the Issuers.  Subject to
Section 2.07 hereof, the Issuers may not issue new Notes to replace Notes in
respect of which they have previously paid all principal, premium and interest
accrued thereon, or delivered to the Trustee for cancellation.

Section 2.11.  Defaulted Interest.
               ------------------

          If the Issuers default in a payment of interest on the Notes, they
shall pay the defaulted amounts, plus any interest payable on defaulted amounts
pursuant to Section 4.01 hereof, to the persons who are Noteholders on a
subsequent special record date.  The Issuers shall fix the special record
<PAGE>

                                     -57-

date and payment date in a manner satisfactory to the Trustee and provide the
Trustee at least 20 days notice of the proposed amount of defaulted interest to
be paid and the special payment date. At least 15 days before the special record
date, the Issuers shall mail or cause to be mailed to each Noteholder at its
address as it appears on the Notes register maintained by the Registrar a notice
that states the special record date, the payment date (which shall be not less
than five nor more than ten days after the special record date), and the amount
to be paid. In lieu of the foregoing procedures, the Issuers may pay defaulted
interest in any other lawful manner satisfactory to the Trustee.

Section 2.12.  Deposit of Moneys.
               -----------------

          Prior to 10:00 a.m., New York City time, on each Interest Payment
Date, Redemption Date and Maturity Date, the Issuers shall have deposited with
the Paying Agent in immediately available funds U.S. legal tender sufficient to
make payments, if any, due on such Interest Payment Date, Redemption Date or
Maturity Date, as the case may be, in a timely manner which permits the Trustee
to remit payment to the Holders on such Interest Payment Date, Redemption Date
or Maturity Date, as the case may be.  The principal and interest on Global
Notes shall be payable to the Depository or its nominee, as the case may be, as
the sole registered owner and the sole holder of the Global Notes represented
thereby.  The principal and interest on Notes in certificated form shall be
payable at the office of the Paying Agent.

Section 2.13.  CUSIP Number.
               ------------

          The Issuers in issuing the Notes may use one or more "CUSIP" numbers,
and if so, the Trustee shall use such CUSIP numbers in notices of redemption or
exchange as a convenience to Holders, provided that any such notice may state
                                      --------
that no representation is made as to the correctness or accuracy of the CUSIP
numbers printed in the notice or on the Notes, and that reliance may be placed
only on the other identification numbers printed on the Notes.
<PAGE>

                                     -58-

Section 2.14.  Book-Entry Provisions for Global Notes.
               --------------------------------------

          (a) The Global Notes initially shall (i) be registered in the name of
the Depository or the nominee of such Depository and (ii) bear legends as set
forth in Exhibit B.

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

          (b) Interests of beneficial owners in the Global Notes may be
transferred or exchanged for Certificated Notes in accordance with the rules and
procedures of the Depository and the provisions of Section 2.15.  In addition,
Certificated Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in Global Notes if (i) the Depository (x) notifies
the Issuers that it is unwilling or unable to continue as Depository for any
Global Note or (y) has ceased to be a clearing company registered under the
Exchange Act and, in each case, a successor depositary is not appointed by the
Issuers within 90 days of such notice, (ii) the Issuers, at their option, notify
the Trustee in writing that they elect to cause the issuance of Certificated
Notes, or (iii) a Default or an Event of Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue
Certificated Notes.

          (c) In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Certificated Notes are to be
issued) reflect on
<PAGE>

                                     -59-

its books and records the date and a decrease in the principal amount of the
Global Note in an amount equal to the principal amount of the beneficial
interest in the Global Note to be transferred, and the Issuers shall execute,
and the Trustee shall upon receipt of a written order from the Issuers
authenticate and make available for delivery, one or more Certificated Notes of
like tenor and amount.

          (d) In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to
be surrendered to the Trustee for cancellation, and the Issuers shall execute,
and the Trustee shall, upon receipt of an authentication order from the Issuers
in the form of an Officers' Certificate, authenticate and deliver, to each
beneficial owner identified by the Depository in writing in exchange for its
beneficial interest in the Global Notes, an equal aggregate principal amount of
Certificated Notes of authorized denominations.

          (e) Any Certificated Note constituting a Restricted Security delivered
in exchange for an interest in a Global Note pursuant to paragraph (b), (c) or
(d) shall, except as otherwise provided by Section 2.15, bear the Private
Placement Legend.

          (f) The Holder of any Global Note may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Notes.

Section 2.15.  Registration of Transfers and Exchanges.
               ----------------------------------------

          (a) Transfer and Exchange of Certificated Notes.  When Certificated
              -------------------------------------------
Notes are presented to the Registrar or co-Registrar with a request:

          (i) to register the transfer of the Certificated Notes; or
<PAGE>

                                     -60-

          (ii) to exchange such Certificated Notes for an equal principal
     amount of Certificated Notes of other authorized denominations,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if the requirements under this Indenture as set forth in this
Section 2.15 for such transactions are met; provided, however, that the
                                            --------  -------
Certificated Notes presented or surrendered for registration of transfer or
exchange:

            (I) shall be duly endorsed or accompanied by a written instrument of
     transfer in form satisfactory to the Registrar or co-Registrar, duly

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

          In the event that less than all of the Notes are to be redeemed at any

compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not listed on a

redemption portions of the principal of the Notes that have denominations larger

CUSIP number(s) thereof) and shall state:

          (1)  the Redemption Date;

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

          (3)  that, if any Note is being redeemed in part, the portion of the

     integral multiple
<PAGE>

                                     -68-

          (6)  that, unless the Issuers default in making the redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the Redemption Date and the only remaining right of the Holders is to
     receive payment of the redemption price plus accrued interest to the
     Redemption Date upon surrender of the Notes to the Paying Agent;

          (7)  the paragraph of Section 3.07 hereof pursuant to which the Notes
     called for redemption are being redeemed; and

          Once the notice of redemption described in Section 3.03 is mailed,
Notes called for redemption become due and payable on the Redemption Date and at
the redemption price, including any premium, plus accrued interest to the
Redemption Date, if any.  Upon surrender to the Paying Agent, such Notes shall
be paid at the redemption price, including any premium, plus accrued interest to
the Redemption Date, if any, provided that if the Redemption Date is after a
                             --------

          On or prior to 10:00 a.m., New York City time, on each Redemption
Date, the Issuers shall have deposited with the Paying Agent in immediately
available funds U.S. legal tender sufficient to pay the redemption price of and
accrued interest on all Notes to be redeemed on that date.

          On and after any Redemption Date, if U.S. legal tender sufficient to
pay the redemption price of and accrued interest on Notes called for redemption
shall have been made available in accordance with the preceding paragraph, the
Notes called for redemption will cease to accrue interest and the only right of
the Holders of such Notes will be to receive payment of the redemption price of
and, subject to the first proviso in Section 3.04, accrued and unpaid interest
on such Notes to the Redemption Date.  If any Note called for redemption shall
not be so paid, interest will continue to accrue and be paid, from the

of the Note and any interest not paid on such unpaid principal, in each case, at
the rate and in the manner provided in the Notes.

(and premium, if any) and interest and other payment obligations in respect of
such Indebtedness shall be subordinate to the prior payment in full of the
Company's Obligations under the Notes such that no payments of principal (or

may be permitted for so long as any Default or Event of Default shall have
occurred and be continuing, (c) that shall automatically convert into common

                                    THE NOTES


Section 2.01. Dating; Incorporation of Form in Indenture.

                  The Notes and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A which is incorporated in and
made part of this Indenture. The Notes may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Issuers may use
"CUSIP" numbers in issuing the Notes. The Issuers shall approve the form of the
Notes. Each Note shall be dated the date of its authentication.

                  Unless the applicable Holder requests Notes in the form of
physical certificated Notes in registered form ("Certificated Notes"), which
shall be substantially in the form of Exhibit A, Notes offered and sold in
reliance on Rule 144A or in offshore transactions in reliance on Regulation S
shall be issued initially in the form of permanent Global Notes in registered
form, substantially in the form set forth in Exhibit A ("Global Notes"),
deposited with the Depository, duly executed by the Issuers and authenticated by
the Trustee as hereinafter provided and shall bear the legend set forth on
Exhibit B. The aggregate principal amount of any Global Note may from time to
time be increased or decreased by adjustments made on the records of the
Depository, as hereinafter provided.

                  Notes offered and sold to Qualified Institutional Buyers in
reliance on Rule 144A issued in the form of one or more Global Notes (the "U.S.
Global Note") shall be registered in the name of the Depository or its nominee
and deposited with the Depository, duly executed by the Issuers and
authenticated by the Trustee as hereinafter provided, for credit by the
Depository to the respective accounts of beneficial owners of the Notes
represented thereby (or such other accounts as they may direct).

                  Notes offered and sold in reliance on Regulation S issued in
the form of Global Notes (the "Regulation S Global Note") shall be registered in
the name of the Depository or its nominee, duly executed by the Issuers and
authenticated by the Trustee as hereinafter provided, for credit by the
Depository to the respective accounts of the beneficial owners of the
<PAGE>
                                      -45-

Notes represented thereby (or such other accounts as they may direct).

                  The Issuers shall cause the U.S. Global Note and the
Regulation S Global Note to have separate CUSIP and ISIN numbers.

Section 2.02. Execution and Authentication.

                  The Notes shall be executed on behalf of the Issuers by two
Officers of each of the Issuers or an Officer and the Secretary of each of the
Issuers. Such signature may be either manual or facsimile. The Issuers' seals
may be impressed, affixed, imprinted or reproduced on the Notes and may be in
facsimile form.

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

                  A Note shall not be valid until the Trustee manually signs the
certificate of authentication on the Note. Such signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

                  The Trustee or an authentication agent shall authenticate (i)
Initial Notes for original issue on the Issue Date in an aggregate principal
amount not to exceed $12,000,000, (ii) one or more series of Notes for original
issue after the Issue Date (such Notes to be substantially in the form of
Exhibit A) in an aggregate principal amount not to exceed $38,000,000 and (iii)
any Additional Notes, in each case upon receipt of an authentication order in
the form of an Officers' Certificate. The aggregate principal amount of Notes
(excluding any Additional Notes) outstanding at any time may not exceed
$50,000,000 except as provided in Section 2.07 hereof. Upon receipt of an
authentication order in the form of an Officers' Certificate, the Trustee shall
authenticate an additional series of Notes for issuance in exchange for all
Notes previously issued pursuant to an exchange offer registered under the
Securities Act (a "Registered Exchange") or pursuant to a Private Exchange (as
defined in the Registration Rights Agreement). Exchange Notes (as defined in the
Registration Rights Agreement) may have such distinctive series designation and
"CUSIP" numbers as and such changes in the form thereof as are specified in the
Officers' Certificate referred to in the preceding sentence. Exchange Notes
issued pursuant to a Registered Exchange shall not bear the Private Placement
Legend.
<PAGE>
                                      -46-

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

                  The Trustee may appoint an authenticating agent to
authenticate Notes. Any such appointment shall be evidenced by an instrument
signed by an authorized officer of the Trustee, a copy of which shall be
furnished to the Issuers. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same right as an Agent to deal with the Issuers or
an Affiliate of any Issuer.

Section 2.03. Registrar, Paying Agent and Calculation Agent.

                  The Issuers shall maintain an office or agency where Notes may
be presented for registration of transfer or for exchange ("Registrar"), an
office or agency located in the Borough of Manhattan, City of New York, State of
New York where Notes may be presented for payment ("Paying Agent") and an office
or agency where notices and demands to or upon the Issuers in respect of the
Notes and this Indenture may be served. The Registrar shall keep a register of
the Notes and of their transfer and exchange. The Registrar shall provide the
Issuers a current copy of such register from time to time upon request of the
Issuers. The Issuers may have one or more co-registrars and one or more
additional paying agents. None of the Issuers nor any Affiliate of the Issuers
may act as Paying Agent or Calculation Agent. The Issuers may change any Paying
Agent, Registrar, co-registrar or Calculation Agent without notice to any
Noteholder.

                  The Issuers shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or Calculation Agent not a party to this
Indenture. The agreement shall implement the provisions of this Indenture that
relate to such Agent. The Issuers shall notify the Trustee of the name and
address of any such Agent. If the Issuers fail to maintain a Registrar, Paying
Agent or Calculation Agent, or agent for service of notices and demands, or fail
to give the foregoing notice, the Trustee shall act as such. The Issuers
initially appoint the Trustee as Registrar, Paying Agent, Calculation Agent and
agent for service of notices and demands in connection with the Notes.

                                      -47-

Section 2.04. Paying Agent to Hold Money in Trust.

                  The Issuers shall require each Paying Agent other than the
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of the Holders or the Trustee all assets held by the Paying Agent for
the payment of principal of, premium, if any, or interest on Notes (whether such
assets have been distributed to it by the Issuers or any other obligor on the
Notes), and shall notify the Trustee in writing of any Default in making any
such payment. The Issuers at any time may require a Paying Agent to distribute
all assets held by it to the Trustee and account for any assets disbursed and
the Trustee may at any time during the continuance of any payment Default, upon
written request to a Paying Agent, require such Paying Agent to forthwith
distribute to the Trustee all assets so held in trust by such Paying Agent
together with a complete accounting of such sums. Upon doing so, the Paying
Agent shall have no further liability for such assets.

Section 2.05. Noteholder Lists.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Noteholders. If the Trustee is not the Registrar, the Issuers shall
furnish to the Trustee on or before each March 1, June 1, September 1, and
December 1 in each year, and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Noteholders.

Section 2.06. Transfer and Exchange.

                  When a Note is presented to the Registrar with a request to
register the transfer thereof, the Registrar shall register the transfer as
requested if the requirements of applicable law are met and, when Notes are
presented to the Registrar with a request to exchange them for an equal
principal amount of Notes of other authorized denominations, the Registrar shall
make the exchange as requested; provided that every Note presented or
surrendered for registration of transfer or exchange shall be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Issuers and the Registrar duly executed by the Holder thereof or his attorney
duly authorized in writing. To permit transfers and exchanges, upon surrender of
any Note for registration of transfer at the office or agency maintained
pursuant to Section 2.03 hereof, the Issuers shall execute and the Trustee shall
<PAGE>
                                      -48-

authenticate Notes at the Registrar's request. Any exchange or transfer shall be
without charge, except that the Issuers may require payment by the Holder of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation to a transfer or exchange, but this provision shall not apply to any
exchange pursuant to Sections 2.09, 3.06 or 8.05 hereof. The Trustee shall not
be required to register transfers of Notes or to exchange Notes for a period of
15 days before selection of any Notes to be redeemed. The Trustee shall not be
required to exchange or register transfers of any Notes called or being called
for redemption in whole or in part, except the unredeemed portion of any Note
being redeemed in part.

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

Section 2.07. Replacement Notes.

                  If a mutilated Note is surrendered to the Trustee or if the
Holder presents evidence to the satisfaction of the Issuers and the Trustee that
the Note has been lost, destroyed or wrongfully taken, the Issuers shall issue
and the Trustee shall authenticate a replacement Note. An indemnity bond may be
required by the Issuers or the Trustee that is sufficient in the judgment of the
Issuers and the Trustee to protect the Issuers, the Trustee or any Agent from
any loss which any of them may suffer if a Note is replaced. In every case of
destruction, loss or theft, the applicant shall also furnish to the Issuers and
to the Trustee evidence to their satisfaction of the destruction, loss or the
theft of such Note and the ownership thereof. Each of the Issuers and the
Trustee may charge for its expenses in replacing a Note. Every replacement Note
is an additional obligation of the Issuers. In the event any such mutilated,
lost, destroyed or wrongfully taken Note has become due and payable, the Issuers
in their discretion may pay such Note instead of issuing a new Note in
replacement thereof. The provisions of this Section 2.07 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.
<PAGE>
                                      -49-

Section 2.08. Outstanding Notes.

                  Notes outstanding at any time are all Notes authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.08 as not outstanding.

                  If a Note is replaced pursuant to Section 2.07, it ceases to
be outstanding until the Issuers and the Trustee receive proof satisfactory to
each of them that the replaced Note is held by a bona fide purchaser.

                  If a Paying Agent holds on a Redemption Date or Maturity Date
money sufficient to pay the principal of, premium, if any, and accrued interest
on Notes payable on that date, then on and after that date such Notes cease to
be outstanding and interest on them ceases to accrue.

                  Subject to Section 12.06, a Note does not cease to be
outstanding solely because the Issuers or any Affiliate of an Issuer hold the
Note.

Section 2.09. Temporary Notes.

                  Until definitive Notes are ready for delivery, the Issuers may
prepare and the Trustee shall authenticate temporary Notes. Temporary Notes
shall be substantially in the form, and shall carry all rights, of definitive
Notes but may have variations that the Issuers consider appropriate for
temporary Notes. Without unreasonable delay, the Issuers shall prepare and the
Trustee shall authenticate definitive Notes in exchange for temporary Notes
presented to it.

Section 2.10. Cancellation.

                  The Issuers at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment. The Trustee
shall cancel and retain or, upon written request of the Issuers, may destroy or
return to the Issuers in accordance with its normal practice, all Notes
surrendered for transfer, exchange, payment or cancellation and if such Notes
are destroyed, deliver a certificate of destruction to the Issuers. Subject to
Section 2.07 hereof, the Issuers may not issue new Notes to replace Notes in
respect of which they have previously paid all principal, premium and interest
accrued thereon, or delivered to the Trustee for cancellation.

                                      -50-

Section 2.11. Defaulted Interest.

                  If the Issuers default in a payment of interest on the Notes,
they shall pay the defaulted amounts, plus any interest payable on defaulted
amounts pursuant to Section 4.01 hereof, to the persons who are Noteholders on a
subsequent special record date. The Issuers shall fix the special record date
and payment date in a manner satisfactory to the Trustee and provide the Trustee
at least 20 days notice of the proposed amount of defaulted interest to be paid
and the special payment date. At least 15 days before the special record date,
the Issuers shall mail or cause to be mailed to each Noteholder at its address
as it appears on the Notes register maintained by the Registrar a notice that
states the special record date, the payment date (which shall be not less than
five nor more than ten days after the special record date), and the amount to be
paid. In lieu of the foregoing procedures, the Issuers may pay defaulted
interest in any other lawful manner satisfactory to the Trustee.

Section 2.12. Deposit of Moneys.

                  Prior to 10:00 a.m., New York City time, on each Interest
Payment Date, Redemption Date and Maturity Date, the Issuers shall have
deposited with the Paying Agent in immediately available funds U.S. legal tender
sufficient to make payments, if any, due on such Interest Payment Date,
Redemption Date or Maturity Date, as the case may be, in a timely manner which
permits the Trustee to remit payment to the Holders on such Interest Payment
Date, Redemption Date or Maturity Date, as the case may be. The principal and
interest on Global Notes shall be payable to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole holder of the Global
Notes represented thereby. The principal and interest on Notes in certificated
form shall be payable at the office of the Paying Agent.

Section 2.13. CUSIP Number.

                  The Issuers in issuing the Notes may use one or more "CUSIP"
numbers, and if so, the Trustee shall use such CUSIP numbers in notices of
redemption or exchange as a convenience to Holders, provided that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP numbers printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes.

Section 2.14. Book-Entry Provisions for Global Notes.

                  (a) The Global Notes initially shall (i) be registered in the

as set forth in Exhibit B.

                  Members of, or participants in, the Depository ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Note held on their behalf by the Depository or under the Global Note, and the
Depository may be treated by the Issuers, the Trustee and any agent of the
Issuers or the Trustee as the absolute owner of the Global Note for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Issuers, the Trustee or any agent of the Issuers or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Agent Members, the

procedures of the Depository and the provisions of Section 2.15. In addition,
Certificated Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in Global Notes if (i) the Depository (x) notifies
the Issuers that it is unwilling or unable to continue as Depository for any
Global Note or (y) has ceased to be a clearing company registered under the
Exchange Act and, in each case, a successor depositary is not appointed by the
Issuers within 90 days of such notice, (ii) the Issuers, at their option, notify
the Trustee in writing that they elect to cause the issuance of Certificated
Notes, or (iii) a Default or an Event of Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue
Certificated Notes.

                  (c) In connection with any transfer or exchange of a portion
of the beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Certificated Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Issuers
shall execute, and the Trustee shall upon receipt of a written order from the
Issuers authenticate and make available for delivery, one or more Certificated
Notes of like tenor and amount.

                  (d) In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall
be deemed to be surrendered to the Trustee for cancellation, and the Issuers
shall execute, and the Trustee shall, upon receipt of an authentication order
from the Issuers in the form of an Officers' Certificate, authenticate and
deliver, to each beneficial owner identified by the Depository in writing in
exchange for its beneficial interest in the Global Notes, an equal aggregate
principal amount of Certificated Notes of authorized denominations.

                  (e) Any Certificated Note constituting a Restricted Security
delivered in exchange for an interest in a Global Note pursuant to paragraph
(b), (c) or (d) shall, except as otherwise provided by Section 2.15, bear the
Private Placement Legend.

                  (f) The Holder of any Global Note may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

shall cancel such Global Notes (or Global Note) and the Issuers shall issue and
the Trustee shall, upon receipt of an authentication order in the form of an
Officers' Certificate in accordance with Section 2.02, authenticate new Global
Notes of the types so cancelled (or the type so cancelled and applicable type

the applicable increase and decrease of the principal amount of Notes
represented by such types of Global Notes, giving effect to such transfer. If
the applicable type of Global Note required to represent the interest as
requested to be transferred is not outstanding at the time of such request, the
Issuers shall issue and the Trustee shall, upon written instructions from the
Issuers in accordance with Section 2.02, authenticate a new Global Note of such
type in principal amount equal to the principal amount of the interest requested
to be transferred.

                  (d) Transfer of a Beneficial Interest in a Global Note for a
Certificated Note. (i) Any Person having a beneficial interest in a Global Note

         certification from such Person to that effect (substantially in the
         form of Exhibit C hereto); or

                  (B) if such beneficial interest is being transferred to a
         Qualified Institutional Buyer in accordance with Rule l44A, a

         to the effect that such transfer is in compliance with the Securities
         Act; or

         form of Exhibit C hereto) and an Opinion of Counsel reasonably
         satisfactory to the Issuers to the effect that such transfer is in
         compliance with the Securities Act,

co-Registrar shall deliver Notes that do not bear the Private Placement Legend.
Upon the transfer, exchange or replacement of Notes bearing the Private

Restriction Termination Date shall have occurred, (ii) there is delivered to the
Trustee an Opinion of Counsel reasonably satisfactory to the Issuers and the

Redemption Date. If any Note called for redemption shall not be so paid,
interest will continue to accrue and be paid, from the Redemption Date until

the manner provided in the Notes and this Indenture. An installment of principal
or interest shall be considered paid on the date it is due if the Trustee or
Paying Agent holds, for the benefit of the Holders, on that date U.S. legal
tender designated for and sufficient to pay such installment. Interest on the
Notes shall be computed as set forth in Exhibit A.

                  The Issuers shall pay interest on overdue principal (including
post-petition interest in a proceeding under any Bankruptcy Law), and interest
on overdue interest, to the extent lawful, at the rate specified in the Notes.

Section 4.02. Provision of Financial Statements and Other Information.

                  (a) Commencing with the first fiscal quarter of the Company
ending after the Issue Date, the Issuers will file with the Commission all
information, documents and reports required
<PAGE>
                                      -64-


to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange
Act and will provide the Trustee and the Noteholders with copies of all such
information, documents and reports within 15 days of filing thereof with the
Commission; provided that if the Issuers are not required to file such
information, documents or reports with the Commission, they will nonetheless
continue to furnish such information, documents and reports required to be filed
by issuers subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act to the Trustee and the Noteholders within 15 days of the date on
which filing with the Commission would have been required. The Issuers shall
also comply with the provisions of TIA ss. 314(a). The Trustee shall retain such
reports, information and documents at its Corporate Trust Office and permit any
Noteholder to examine such material upon prior written request at reasonable
times. Except to determine whether the Issuers have complied with the provisions
of this Section 4.02, the Trustee shall not be required to examine or review
such material or any of it and shall not be considered to have had notice,
constructive or otherwise, from anything set forth in such material of any
Default or other fact or event which might require the Trustee to take any
action or give any notice hereunder.

                  (b) The Issuers will, upon request, provide to any Holder or
any prospective transferee of any such Holder any information concerning the

Holder to sell or transfer Notes in compliance with Rule 144 and Rule 144A under
the Securities Act.

Section 4.03. Waiver of Stay, Extension or Usury Laws.

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

Section 4.04. Compliance Certificate; Notice of Default; Tax Information.

                  (a) The Issuers shall deliver to the Trustee, within 120 days
after the end of each fiscal year, an Officers' Certificate (one of the signers
of which shall be the principal executive officer, principal financial officer
or principal accounting officer of each Issuer) stating that a review of the
activities of the Issuers and their Subsidiaries during such fiscal year has
been made under the supervision of the signing Officers with a view to
determining whether the Issuers have kept, 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 have kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and, in the case of Restricted Payments, listing all
Restricted Payments for such quarter, and are not in default in the performance
or observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all of such Defaults
or Events of Default of which he or she may have knowledge and what action each
is 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
are prohibited or if such event has occurred, a description of the event and
what action the Issuers are taking or propose to take with respect thereto.

                  (b) The Issuers will, 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.

                  (c) The annual financial statements delivered pursuant to
Section 4.02 shall be accompanied by a written report of the Issuers'
independent accountants (who shall be a firm of established national reputation)
that in conducting their audit of such financial statements nothing has come to
their attention that would lead them to believe that any Issuer has violated any
material provisions of Article Four, Five or Six of this Indenture insofar as
they relate to accounting matters 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
<PAGE>
                                      -66-

Person for any failure to obtain knowledge of any such violation.

                  (d) The Issuers shall calculate and deliver to the Trustee all
original issue discount information to be reported by the Trustee to Holders as
required by law.

Section 4.05. Taxes.

                  The Issuers shall, and shall cause each of their Subsidiaries
to, pay prior to delinquency all material taxes, assessments, and governmental
levies except as contested in good faith and by appropriate proceedings.

Section 4.06. Limitation on Additional Indebtedness.

                  (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, incur (as defined) any
Indebtedness (including Acquired Indebtedness); provided that if no Default or
Event of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of such Indebtedness, the Issuers and any of the
Guarantors may incur Indebtedness (including Acquired Indebtedness) if after
giving effect to the incurrence of such Indebtedness and the receipt and
application of the proceeds thereof, the Company's Consolidated Leverage Ratio
is less than 6.5 to 1 if such Indebtedness is incurred on or before March 15,
2001 and 6.0 to 1 if such Indebtedness is incurred thereafter.

                  (b) Notwithstanding the foregoing clause (a), the Company and
its Restricted Subsidiaries may incur Permitted Indebtedness. For purposes of
determining compliance with this Section 4.06, in the event that an item of
proposed Indebtedness meets the criteria of more than one of the categories of
Permitted Indebtedness as of the date of incurrence thereof or is entitled to be
incurred pursuant to the first paragraph of this covenant as of the date of
incurrence thereof, the Company shall, in its sole discretion, classify or
reclassify such item of Indebtedness in any manner that complies with this
covenant. 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 and the payment of
dividends on Disqualified Capital Stock in the form of additional shares of the
same class of Disqualified Capital Stock will not be deemed an issuance of
Disqualified Capital Stock.

Section 4.07. Limitation on Restricted Payments.

Restricted Subsidiaries to, directly or indirectly, make, any Restricted
Payment, unless:

                  (1) no Default or Event of Default shall have occurred and be
         continuing at the time of or immediately after giving effect to such
         Restricted Payment;

                  (2) immediately after giving pro forma effect to such
         Restricted Payment, the Company could incur $1.00 of additional
         Indebtedness (other than Permitted Indebtedness) under Section 4.06 of
         this Indenture; and

                  (3) immediately after giving effect to such Restricted
         Payment, the aggregate of all Restricted Payments declared or made
         after the Issue Date does not exceed the sum of

                           (a) 100% of the Company's Cumulative EBITDA (or, in
                  the event that such Cumulative EBITDA shall be a deficit,
                  minus 100% of such deficit) minus 1.4 times the Company's
                  Cumulative Consolidated Interest Expense,

                           (b) 100% of the aggregate net cash proceeds received

                  of the Company) of the Company or any Indebtedness or other
                  securities of the Company convertible into or exercisable or
                  exchangeable for Capital Stock (other than Disqualified
                  Capital Stock) of the Company which have been so converted,
                  exercised or exchanged, as the case may be,

                           (c) without duplication of any amounts included in
                  clause (3)(b) above, 100% of the aggregate net proceeds
                  (including the fair market value of Property other than cash)
                  received by the Company from any equity contribution from a
                  holder of the Company's Capital Stock (provided that the net
                  proceeds from the ABRY Equity Contributions shall be excluded
                  from such calculation and, if applicable, from clause (b)
                  above, until the Conversion Date), excluding, in the case of
                  clauses (3)(b) and (c), (i) any net proceeds

                                     (i) the aggregate amount returned in cash
                           on or with respect to Investments (other than
                           Permitted Investments) made subsequent to the
                           Existing Notes Issue Date whether through interest
                           payments, principal payments, dividends or other
                           distributions;

                  Subsidiary as a Restricted Subsidiary, the fair market value
                  of the net assets of such Subsidiary;

         provided, however, that the sum of clauses (d)(i), (ii) and (iii) above
         shall not exceed the aggregate amount of all such Investments made
         subsequent to the Existing Notes Issue Date.

                  For purposes of determining under clause (3) above the amount
expended for Restricted Payments, cash distributed shall be valued at the face
amount thereof and Property other than cash shall be valued at its fair market
value.

                  (b) The provisions of this Section 4.07 shall not prohibit

                  (1) the payment of any distribution within 60 days after the
         date of declaration thereof, if at such date of declaration such

         Indebtedness of the Company (other than any Indebtedness owed to a
         Subsidiary) that is Refinancing Indebtedness,

         solely as a result of the Company (and any intermediate entity through
         which the holder owns such shares) being a limited liability company,

         retirement for value of any Capital Stock of the Company or the payment
         of a dividend to Holdings to effect the repurchase, redemption or other

                  The Company will not, and will not permit any of the
Guarantors to, directly or indirectly, incur, contingently or otherwise, any
Indebtedness (other than the Notes and the Guarantees, as the case may be) that
is both (i) subordinated in right of payment to any Senior Indebtedness of the
Company or Guarantor Senior Indebtedness of any of the Guarantors, as the case
may be, and (ii) senior in right of payment to the Notes and the respective
Guarantee of any such Guarantor, as the case may be. For purposes of this
covenant, Indebtedness is deemed to be senior in right of payment to the Notes
or the Guarantees, as the case may be, if it is not explicitly subordinated in
right of payment to Senior Indebtedness or Guarantor Senior Indebtedness, as the
case may be, at least to the same extent as the Notes and the Guarantees, as the
case may be, are subordinated to such Senior Indebtedness or Guarantor Senior
Indebtedness, as the case may be.

Section 4.09. Limitation on Certain Asset Sales.

                  (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless

                  (1) the Company or such Restricted Subsidiary, as the case may
         be, receives consideration at the time of such sale or other
         disposition at least equal to the fair market value of the assets sold
         or otherwise disposed of (as determined in good faith by the Board of
         Directors of the Company, and evidenced by a Board Resolution);

                  (2) not less than 75% of the consideration received by the
         Company or such Restricted Subsidiary, as the case may be, is in the
         form of cash or Cash Equivalents and/or a controlling interest in a
         Person whose assets are useful to the Company, or any combination
         thereof, except to the extent to which the Company is undertaking a
         Permitted Asset Swap; 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 any of its Restricted Subsidiaries (other than
                  contingent liabilities and liabilities that are by their terms
                  subordinated to the Notes) that are assumed by the transferee
                  of any such assets shall be deemed to be cash for purposes of
                  this clause (2); and

                           (b) any securities, notes or other obligations
                  received by the Company or any such Restricted Subsidiary from
                  such transferee that are promptly 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 clause (2); and

                  (3) the Asset Sale Proceeds received by the Company or such
         Restricted Subsidiary are applied

                           (a) first, to the extent the Company or any such
                  Restricted Subsidiary, as the case may be, elects, or is
                  required, to prepay, repay or purchase indebtedness under any
                  then existing Senior Indebtedness of the Company or any such
                  Restricted Subsidiary within 360 days following the receipt of
                  the Asset Sale Proceeds from any Asset Sale; provided that any
                  such repayment shall result in a permanent reduction
<PAGE>
                                      -73-

                  of the commitments thereunder in an amount equal to the
                  principal amount so repaid;

                           (b) second, to the extent of the balance of Asset
                  Sale Proceeds after application as described above, to the
                  extent the Company elects, to an investment in assets
                  (including Capital Stock or other securities purchased in
                  connection with the acquisition of Capital Stock or Property
                  of another Person) used or useful in businesses reasonably
                  related, ancillary or complementary to the business of the
                  Company or any such Restricted Subsidiary as conducted on the
                  Issue Date; provided that such investment occurs within 360
                  days following receipt of such Asset Sale Proceeds; and

                           (c) third, if on such 360th day with respect to any
                  Asset Sale, the Available Asset Sale Proceeds exceed $10
                  million, the Company shall apply an amount equal to the
                  Available Asset Sale Proceeds to an offer to repurchase the
                  Notes and all other pari passu Indebtedness of the Company
                  containing provisions substantially similar to those set forth
                  in this Indenture regarding offers to purchase or redeem with
                  Asset Sale Proceeds, in each case, at a purchase price in cash
                  equal to 100% of the principal amount thereof plus accrued and
                  unpaid interest, if any, to the purchase date (an "Excess
                  Proceeds Offer").

                  If an Excess Proceeds Offer is not fully subscribed, the
Company may retain the portion of the Available Asset Sale Proceeds not required
to repurchase Notes and such pari passu Indebtedness.

                  Pending the final application of any Asset Sale Proceeds, the
Company or such Restricted Subsidiary may temporarily reduce Indebtedness under
a revolving credit facility, if any, or otherwise invest such Asset Sale
Proceeds in Cash Equivalents.

                  (b) If the Company is required to make an Excess Proceeds
Offer, the Company shall within 45 days following the date specified in
subparagraph (a)(3)(c) above (i) cause a notice of the Excess Proceeds Offer to
be sent at least once to the Dow Jones News Service or similar business news
service in the United States and (ii) mail a notice of the Excess Proceeds Offer
to the Trustee and the Holders. Such notice shall be sent by first-class mail,
postage prepaid, to the Trustee and
<PAGE>
                                      -74-

to each Noteholder, at the address appearing in the register maintained by the
Registrar of the Notes, and shall state:

                  (i) that the Excess Proceeds Offer is being made pursuant to
         this Section 4.09;

                  (ii) that such Holders have the right to require the Company
         to apply the Available Asset Sale Proceeds to repurchase such Notes at
         a purchase price in cash equal to 100% of the principal amount thereof
         plus accrued and unpaid interest, if any, to the purchase date which
         shall be no earlier than 45 days and not later than 60 days from the
         date such notice is mailed (the "Excess Proceeds Payment Date");

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

                  (iv) that any Notes accepted for payment pursuant to the
         Excess Proceeds Offer shall cease to accrue interest after the Excess
         Proceeds Payment Date;

                   (v) that Holders accepting the offer to have their Notes
         purchased pursuant to an Excess Proceeds Offer will be required to
         surrender the Notes, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Note completed, to the Paying Agent at
         the address specified in the notice prior to the close of business on
         the Business Day preceding the Excess Proceeds Payment Date;

                  (vi) that Holders will be entitled to withdraw their
         acceptance of the Excess Proceeds Offer if the Paying Agent receives,
         not later than the close of business on the third Business Day
         preceding the Excess Proceeds Payment Date, a facsimile transmission or
         letter setting forth the name of the Holder, the principal amount of
         the Notes delivered for purchase, and a statement that such Holder is
         withdrawing his election to have such Notes purchased;

                 (vii) that if the aggregate principal amount of Notes
         surrendered by Holders exceeds the amount of Excess Proceeds, Company
         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);
<PAGE>
                                      -75-

                (viii) 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, provided that each Note purchased and
         each such new Note issued shall be in an original principal amount in
         denominations of $1,000 and integral multiples thereof;

                  (ix) the calculations used in determining the amount of
         Available Asset Sale Proceeds to be applied to the purchase of such
         Notes;

                  (x) any other procedures that a Holder must follow to accept
         an Excess Proceeds Offer or effect withdrawal of such acceptance; and

                  (xi) the name and address of the Paying Agent.

                  On the Excess Proceeds Payment Date, the Issuers shall, to the
extent lawful, (i) accept for payment, on a pro rata basis to the extent
necessary, Notes or portions thereof validly tendered pursuant to the Excess
Proceeds Offer, (ii) deposit with the Paying Agent money sufficient to pay the
purchase price plus accrued and unpaid interest, if any, on the Notes to be
purchased or portions thereof, (iii) deliver or cause to be delivered to the
Trustee Notes so accepted together with 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 4.09. The Paying Agent shall promptly
mail to each Holder so accepted payment in an amount equal to the purchase price
for such Notes, and the Issuers shall execute and issue, and the Trustee shall
promptly authenticate and make available for delivery to such Holder, a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered;
provided that each such new Note shall be issued in an original principal amount
in denominations of $1,000 and integral multiples thereof. The Issuers will
publicly announce the results of the Excess Proceeds Offer on the Excess
Proceeds Payment Date.

                  (c) In the event of the transfer of substantially all of the
Property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 5.01 of this
Indenture below but which transaction does not constitute a Change of Control,
the successor Person shall be deemed to have sold the properties and assets of
the Issuers and their Restricted Subsidiaries not so transferred for purposes of
this covenant, and shall comply
<PAGE>
                                      -76-

with the provisions of this Section 4.09 with respect to such deemed sale as if
it were an Asset Sale.

                  (d) The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of Notes pursuant to an Excess Proceeds Offer. To the extent
that the provisions of any securities laws or regulations conflict with this
Section 4.09, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.09 by virtue thereof.

Section 4.10. Limitation on Transactions with Affiliates.

                  (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, enter into or suffer to
exist any transaction or series of related transactions (including, without
limitation, the sale, purchase, exchange or lease of assets, Property or
services) with any Affiliate (each an "Affiliate Transaction") or extend, renew,
waive or otherwise modify the terms of any Affiliate Transaction entered into
prior to the Issue Date unless

                  (1) such Affiliate Transaction is between or among the Company
         and its Restricted Subsidiaries; or

                  (2) the terms of such Affiliate Transaction are at least as
         favorable as the terms which could be obtained by the Company or such
         Restricted Subsidiary, as the case may be, in a comparable transaction
         made on an arm's-length basis between unaffiliated parties.

                  In any Affiliate Transaction (or any series of related
Affiliate Transactions which are similar or part of a common plan) involving an
amount or having a fair market value in excess of $2.5 million which is not
permitted under clause (1) above, the Company must obtain a Board Resolution of
the Company certifying that such Affiliate Transaction complies with clause (2)
above. In any Affiliate Transaction (or any series of related Affiliate
Transactions which are similar or part of a common plan) involving an amount or
having a fair market value in excess of $10 million which is not permitted under
clause (1) above, the Company must obtain a favorable written opinion as to the
fairness of such transaction or transactions, as the case may be, from an
Independent Financial Advisor.
<PAGE>
                                      -77-

                  (b) The foregoing provisions will not apply to

                  (1) any Restricted Payment that is not prohibited by the
         provisions described under Section 4.07 of this Indenture,

                  (2) reasonable fees and compensation paid to, and indemnity
         provided on behalf of, officers, Directors, employees or consultants of
         the Company or any Restricted Subsidiary of the Company as determined
         in good faith by the Company's Board of Directors or senior management,

                  (3) any agreement as in effect as of the Issue Date or any
         amendment thereto or any transaction contemplated thereby (including
         pursuant to any amendment thereto) in any replacement agreement thereto
         so long as any such amendment or replacement agreement is not more
         disadvantageous to the Holders in any material respect than the
         original agreement as in effect on the Issue Date,

                  (4) transactions effected as part of a Qualified
         Securitization Transaction,

                  (5) any employment agreement entered into by the Company or
         any of its Restricted Subsidiaries in the ordinary course of business,
         and advances to employees for moving, entertainment and travel
         expenses, drawing accounts and similar expenditures in the ordinary
         course of business,

                  (6) the existence of, or the performance by the Company or any
         of its Restricted Subsidiaries of its obligations under the terms of,
         any securityholders agreement (including any registration rights
         agreement or purchase agreement related thereto) to which it is a party
         as of the Issue Date and any similar agreements which it may enter into
         thereafter; provided, however, that the existence of, or the
         performance by the Company or any of its Restricted Subsidiaries of
         obligations under, any future amendment to any such existing agreement
         or under any similar agreement entered into after the Issue Date shall
         only be permitted by this clause (6) to the extent that the terms of
         any such amendment or new agreement are not otherwise disadvantageous
         to the Holders in any material respect,

                  (7) transactions permitted by, and complying with, the
         provisions described under Article 5 of this Indenture below,
<PAGE>

         venture partners or purchasers or sellers of goods or services, in each
         case in the ordinary course of business (including, without limitation,
         pursuant to joint venture agreements) and otherwise in compliance with
         the terms of this Indenture which are fair to the Company or its
         Restricted Subsidiaries, in the reasonable determination of the Board
         of Directors of the Company or the senior management thereof, or are on
         terms at least as favorable as might reasonably have been obtained at
         such time from an unaffiliated party,

                  (10) [RESERVED]

                  (11) transactions pursuant to the ABRY Management Agreement or
         pursuant to the terms of any amendment thereto or restatement thereof
         which terms are not more disadvantageous to the Holders in any material
         respect than the terms of such agreement as in effect on the Issue Date
         as determined in good faith by the Board of Directors of the Company
         and evidenced by a Board Resolution, and

                  (12) with regard to the requirement to obtain the opinion of
         an Independent Financial Advisor only, the issuance of Capital Stock of
         the Company; provided that said issuance has been approved by the Board
         of Directors of the Company and the Board Resolution described in the
         immediately preceding paragraph has been delivered to the Trustee.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, create, incur or otherwise cause or suffer to exist

Property or asset of the Company or any of its Restricted Subsidiaries or any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary of the
Company which owns Property or assets, now owned or hereafter acquired, unless

                  (1) if such Lien secures Indebtedness which is subordinated to
         the Notes, any such Lien shall be subordinated to any Lien granted to
         the Holders to the same extent as such Indebtedness is subordinated to
         the Notes and
<PAGE>
                                      -79-

                  (2) in all other cases, the Notes are equally and ratably
         secured.

Section 4.12. Limitations on Investments

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, make any Investment other than

                  (1)  a Permitted Investment or

                  (2) an Investment that is made after the Issue Date as a
         Restricted Payment in compliance with Section 4.07.

Section 4.13. Limitation on Sale and Lease-Back Transactions.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, enter into any Sale and Lease-Back Transaction
unless

                  (1) the consideration received in such Sale and Lease-Back
         Transaction is at least equal to the fair market value of the Property
         sold, as determined in good faith by the Board of Directors of the
         Company and evidenced by a Board Resolution,

                  (2) the Company could incur the Attributable Indebtedness in
         respect of such Sale and Lease-Back Transaction in compliance with
         Section 4.06 and

                  (3) the transfer of assets in such Sale and Lease-Back
         Transaction is permitted by, and the Company or such Restricted
         Subsidiary applies the proceeds of such transaction in compliance with
         Section 4.09.

Section 4.14. Payments for Consent.

                  The Company will not, and will not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder for
or as an inducement to any consent, waiver or amendment of any of the terms or

to be paid or agreed to be paid to all Holders which so consent, waive or agree
to amend in the time frame set forth in solicitation documents relating to such
consent, waiver or agreement.

Section 4.15. Corporate Existence.

                  Subject to Article 5 hereof, each of the Issuers shall do or
cause to be done all things necessary to preserve and keep in full force and
effect (i) its corporate or limited liability company existence, and the
corporate, partnership or limited liability company or other existence of each
Subsidiary, in accordance with the respective organizational documents (as the
same may be amended from time to time) of each Subsidiary and, within thirty
days of the Issue Date, the material rights (charter and statutory), licenses
and franchises of the Issuers and their Subsidiaries except where the failure to
preserve and keep in full force and effect any such rights, licenses and
franchise shall not have a material adverse effect on the financial condition,
business, operations or prospects of the Issuers and their Subsidiaries taken as
a whole; and provided that the Issuers shall not be required to preserve any
such right, license or franchise, or the corporate, limited liability company,
partnership or other existence of any of Subsidiaries, if the Board of Directors
of the applicable Issuer shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Issuers and their
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders.

                  (a) Upon the occurrence of a Change of Control, the Issuers

                  (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 Date;

                  (6) that Holders will be entitled to withdraw their acceptance

         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered;

                  (8) any other procedures that a Holder must follow to accept a
         Change of Control Offer or effect withdrawal of such acceptance; and

and issue, and the Trustee shall promptly authenticate and mail to such Holder,
a new Note equal in principal amount to any unpurchased portion of the Notes

principal amount in denominations of $1,000 and integral multiples thereof.

                  (c) If the Senior Credit Facility is in effect, or any amounts

Control, the Issuers covenant to

                  (1) repay in full all obligations and terminate all
         commitments under or in respect of the Senior Credit Facility and all

with the repurchase of Notes pursuant to a Change of Control Offer. To the

and regulations and shall not be deemed to have breached their obligations under
this Section 4.16 by virtue thereof.

Indenture may be served. The Issuers 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
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee as set forth in Section 12.02.

                  The Issuers may also from time to time designate one or more

any or all such purposes and may from time to time rescind such designations.
The Issuers shall give prompt written notice to the Trustee of such designation
or rescission and of any change in the location of any such other office or
agency.

         such transaction, no Default or Event of Default shall have occurred
         and be continuing; and

                  (3) immediately after giving effect to such transaction on a
         pro forma basis the Company or such Person could incur at least $1.00
         of additional Indebtedness (other than Permitted Indebtedness) under

purpose of changing the jurisdiction of organization of the Company or the form
of organization of the Company so long as the amount of Indebtedness of the
Company and its Restricted Subsidiaries is not increased thereby and that the
successor assumes all obligations of the Company under this Indenture, the Notes

                  The term "Bankruptcy Law" means Title 11, U.S. Code or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.

                  The Trustee may withhold notice to the Holders of any Default
(except in payment of principal or premium, if any, or interest on the Notes) if
the Trustee considers it to be in the best interest of the Holders to do so.

Section 6.02. Acceleration.

                  If an Event of Default (other than an Event of Default of the
type described in Section 6.01(f) or (g)) shall have occurred and be continuing,
then the Trustee or the holders of not less than 25% in aggregate principal
amount of the Notes then outstanding may declare to be immediately due and
payable the entire principal amount of all the Notes then outstanding plus
accrued interest to the date of acceleration and (1) the same shall become
immediately due and payable or (2) if there are any amounts outstanding under
the Senior Credit Facility, shall become immediately due and payable upon the
first to occur of an acceleration under the Senior Credit Facility or five
Business Days after receipt by the Issuers and the representative under the
Senior Credit Facility of a notice of acceleration; provided, however, that
after such acceleration but before a judgment or decree based on acceleration is
obtained by the Trustee, the holders of a majority in aggregate principal amount
of outstanding Notes may, under certain circumstances, rescind and annul such
acceleration if

                  (1) all Events of Default, other than nonpayment of principal,
         premium, if any, or interest that has become due solely because of the
         acceleration, have been cured or waived as provided in this Indenture,
<PAGE>
                                      -93-

                  (2) to the extent the payment of such interest is lawful,
         interest on overdue installments of interest and overdue principal,
         which has become due otherwise than by such declaration of
         acceleration, has been paid,

                  (3) the Issuers have paid the Trustee its reasonable
         compensation and reimbursed the Trustee for its expenses, disbursements
         and advances and

                  (4) in the event of the cure or waiver of an Event of Default
         of the type described in Section 6.01(f) or (g) above, the Trustee
         shall have received an Officers' Certificate and an Opinion of Counsel
         that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto. In case an Event of Default of the type described in Section
6.01(f) or (g) above shall occur, the principal, premium and interest amount
with respect to all of the Notes shall be due and payable immediately without
any declaration or other act on the part of the Trustee or the Noteholders.

Section 6.03. Other Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, or premium, if any, and interest on the Notes or to
enforce the performance of any provision of the Notes, the obligations set forth
in the Guarantees or this Indenture and may take any necessary action requested
of it as Trustee to settle, compromise, adjust or otherwise conclude any
proceedings to which it is a party.

                  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 Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

Section 6.04. Waiver of Past Defaults and Events of
              Default.

                  Subject to Sections 6.02, 6.07 and 8.02 hereof, the Holders of
a majority in principal amount of the Notes then
<PAGE>
                                      -94-

outstanding shall have the right to waive past Defaults under this Indenture
except a Default in the payment of the principal of, or interest or premium, if
any, on any Note, which cannot be waived without the consent of the Holder of
such Notes or in respect of a covenant or a provision which cannot be modified
or amended without the consent of all Holders. 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 Event of Default or
impair any right consequent thereto.

Section 6.05. Control by Majority.

                  The Holders of a majority in principal amount of the
outstanding Notes have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee by this Indenture. The Trustee,
however, may refuse to follow any direction that conflicts with law or this
Indenture or that the Trustee determines may be unduly prejudicial to the rights
of another Noteholder not taking part in such direction, and the Trustee shall
have the right to decline to follow any such direction if the Trustee, being
advised by counsel, determines that the action so directed may not lawfully be
taken or if the Trustee in good faith shall, by a Trust Officer, determine that
the proceedings so directed may involve it in personal liability; provided that
the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

Section 6.06. Limitation on Suits.

                  Subject to Section 6.07 below, no Holder has any right to
institute any proceeding with respect to this Indenture or any remedy thereunder
unless:

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

                  (2) such Holder or Holders offer to the Trustee indemnity
         reasonably satisfactory to the Trustee against any loss, liability or
         expense which may be incurred in compliance with such request;
<PAGE>
                                      -95-

                  (3) the Trustee fails to institute such proceeding within 60
         calendar days after receipt of such notice and the offer of indemnity;
         and

                  (4) the Trustee has not received directions inconsistent with
         such written request during such 60-day period by the Holders of a
         majority in aggregate principal amount of the outstanding Notes.

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

Section 6.07. Rights of Holders to Receive Payment.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of principal of, or premium, if any, or
accrued interest of any Note held by such Holder on or after the respective due
dates expressed in such Note, or to bring suit for the enforcement of any such
payment on or after such respective dates, is absolute and unconditional and
shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee.

                  If an Event of Default in payment of principal, premium or
interest specified in Section 6.01(a), (b) or (c) hereof occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against any or all of the Issuers and the Guarantors for the
whole amount of unpaid principal and accrued interest remaining unpaid, together
with interest on overdue principal and, to the extent that payment of such
interest is lawful, interest on overdue installments of interest, in each case
at the rate then borne by the Notes, and such further amounts 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 may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Noteholders allowed in any judicial proceedings relative to the Issuers (or
<PAGE>
                                      -96-

any other obligor upon the Notes), its creditors or its Property and shall be
entitled and empowered to collect and receive any monies or other Property
payable or deliverable on any such claims and to distribute the same after
deduction of its charges and expenses to the extent that any such charges and
expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
Noteholder 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
Noteholders, 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.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan or reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceedings.

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 for amounts due under Section 7.07
         hereof;

                  SECOND: to Noteholders for amounts due and unpaid on the Notes
         for principal, premium, if any, and interest as to each, ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on the Notes; and

                  THIRD: to the Issuers or, to the extent the Trustee collects
         any amounts from any Guarantor, to such Guarantor.

                  The Trustee may fix a record date and payment date for any
payment to Noteholders 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
<PAGE>
                                      -97-

any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 hereof or a suit by Holders
of more than 10% in principal amount of the Notes then outstanding.


                                    ARTICLE 7

                                     TRUSTEE


Section 7.01. Duties of Trustee.

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

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

                  (1) The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others.

                  (2) In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture but, in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.

                  (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:
<PAGE>
                                      -98-

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

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

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

                  (4) No provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its rights or powers if it
         determines in the exercise of its reasonable discretion that repayment
         of such funds or adequate indemnity satisfactory to it against such
         risk or liability is not reasonably assured to it.

                  (d) The Trustee is not under any obligation to exercise any of
its rights or powers at the request or direction of any of the Holders unless
such Holders shall have offered to the Trustee indemnity or security
satisfactory to it in its reasonable discretion against any loss, liability,
expense or fee.

                  (e) 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.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by the law.

                  (f) The Trustee shall not be deemed to have knowledge of any
Default or fact or event which might require the Trustee to take any action or
give any notice unless one of its Trust Officers has actual knowledge thereof.

                  (g) The Trustee is also being appointed, and may serve
contemporaneously with its service hereunder, as Trustee under the Senior
Discount Notes Indenture and shall not be considered to be conflicted in its
duties under either the Senior Discount Notes Indenture or this Indenture by
reason of its acting as trustee under the other. After an Event of Default (as
defined in the respective Indenture) under either the Senior Discount Notes
Indenture or this Indenture, and in order that it might not be conflicted in the
performance of its du-
<PAGE>
                                      -99-

ties under either Indenture, the Trustee shall resign as trustee under one of
the Indentures; provided, however, that until the appointment of a successor
Trustee, the Trustee shall not be considered to have violated the standard set
forth in Section 7.01(a) hereof by continuing to act as Trustee under both the
Senior Discount Notes Indenture and this Indenture if it separates the
performance of its discretionary duties under the Senior Discount Notes
Indenture and this Indenture within its corporate trust department and retains
separate counsel for itself as trustee under each of such Indentures.

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

Section 7.02. Rights of Trustee.

                  Subject to Section 7.01 hereof:

                  (1) The Trustee may rely on any document reasonably believed
         by it to be genuine and to have been signed or presented by the proper
         Person. The Trustee need not investigate any fact or matter stated in
         the document.

                  (2) Before the Trustee acts or refrains from acting with
         respect to any matters contemplated by this Indenture or the Notes it
         may require an Officers' Certificate or an Opinion of Counsel, or both,
         which shall conform to the provisions of Section 12.05 hereof. The
         Trustee shall be protected and shall not be liable for any action it
         takes or omits to take in good faith in reliance on such certificate or
         opinion.

                  (3) The Trustee may act through Agents and shall not be
         responsible for the misconduct or negligence of any agent so long as
         the appointment of such agent was made with due care.

                  (4) The Trustee shall not be liable for any action it takes or
         omits to take in good faith which it reasonably believes to be
         authorized or within its rights or powers.

                  (5) The Trustee may consult with counsel of its selection, and
         the advice or opinion of such counsel as to matters of law shall be
         full and complete authorization and protection from liability in
         respect of any action
<PAGE>
                                     -100-

         taken, omitted or suffered by it hereunder in good faith and in
         accordance with the advice or opinion of such counsel.

Section 7.03. Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for or otherwise deal with the Issuers, or any Affiliates
thereof, with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. The Trustee, however, shall be 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 or the Notes, it
shall not be accountable for the Issuers' use of the proceeds from the sale of
Notes or any money paid to the Issuers pursuant to the terms of this Indenture
and it shall not be responsible for any statement in the Notes other than its
certificate of authentication.

Section 7.05. Notice of Defaults.

                  If a Default occurs and is continuing and if it is known to
the Trustee, the Trustee shall mail to each Noteholder notice of the Default
within 30 days after it occurs. Except in the case of a Default in payment of
the principal of, or premium, if any, or interest on any Note the Trustee may
withhold the notice if and so long as the board of directors of the Trustee, the
executive committee or any trust committee of such board and/or its Trust
Officers in good faith determine(s) that withholding the notice is in the
interests of the Noteholders.

Section 7.06. Reports by Trustee to Holders.

                  If required by TIA Section 313(a), within 60 days after May 15
of any year, commencing the May 15 following the date of this Indenture, the
Trustee shall mail to each Noteholder a brief report dated as of such May 15
that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b)(2). The Trustee shall also transmit by mail all reports as
required by TIA Section 313(c) and TIA Section 313(d).
<PAGE>
                                     -101-

                  Reports pursuant to this Section 7.06 shall be transmitted by
mail:

                  (1) to all registered Holders, as the names and addresses of
         such Holders appear on the Registrar's books; and

                  (2) to such Holder as have, within the two years preceding
         such transmission, filed their names and addresses with the Trustee for
         that purpose.

                  A copy of each report at the time of its mailing to
Noteholders shall be filed with the Commission and each stock exchange on which
the Notes are listed. The Issuers shall promptly notify the Trustee when the
Notes are listed on any stock exchange.

Section 7.07. Compensation and Indemnity.

                  The Issuers shall pay to the Trustee from time to time such
compensation as shall be agreed in writing between the Issuers and the Trustee
for its services hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust). The Issuers shall reimburse the Trustee upon request for all reasonable
disbursements, expenses and advances incurred or made by it in connection with
its duties under this Indenture, including the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

                  The Issuers shall indemnify each of the Trustee and its
officers, directors, employees and agents and any predecessor Trustee and its
officers, directors, employees and agents for, and hold each of them harmless
against, any and all loss, damage, claim, liability or expense, including taxes
(other than taxes based on the income of the Trustee) incurred by any of them in
connection with the acceptance or performance of its duties under this Indenture
including the reasonable costs and expenses of defending themselves against any
claim or liability in connection with the exercise or performance of any of the
powers or duties of the Trustee hereunder (including, without limitation,
settlement costs). The Trustee shall notify the Issuers in writing promptly of
any claim asserted against the Trustee or any such officer, director, employee
or agent for which any of them may seek indemnity. However, the failure by the
Trustee to so notify the Issuers shall not relieve the Issuers of their
obligations hereunder except to the extent the Issuers are prejudiced thereby.
This indemnity shall survive
<PAGE>
                                     -102-

the termination of this Indenture, final payment of the Notes, and resignation
or removal of the Trustee.

                  Notwithstanding the foregoing, the Issuers need not reimburse
the Trustee or any such officer, director, employee or agent for any expense or
indemnify any of them against any loss or liability incurred by the Trustee or
any such officer, director, employee or agent through its negligence, willful
misconduct or bad faith. To secure the payment obligations of the Issuers 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 such money or Property held
in trust to pay principal of and interest on particular Notes.

                  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 are intended to constitute expenses of
administration under any Bankruptcy Law.

                  For purposes of this Section 7.07, the term "Trustee" shall
include any trustee appointed pursuant to Article 9.

Section 7.08. Replacement of Trustee.

                  The Trustee may resign by so notifying the Issuers in writing.
The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by notifying the removed Trustee in writing and may appoint a
successor Trustee with the Issuers' written consent which consent shall not be
unreasonably withheld. The Issuers may remove the Trustee at its election if:

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

                  (2) the Trustee is adjudged a bankrupt or an insolvent;

                  (3) a receiver or other public officer takes charge of the
         Trustee or its Property; or

                  (4) the Trustee otherwise 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.
<PAGE>
                                     -103-

                  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 a majority in principal amount of the outstanding
Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

                  If the Trustee fails to comply with Section 7.10 hereof, any
Noteholder 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. Immediately following
such delivery, the retiring Trustee shall, subject to its rights under Section
7.07 hereof, transfer all property held by it as Trustee to the successor
Trustee, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Noteholder. Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Issuers' obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Consolidation, Merger or Conversion.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust assets to, another
corporation, subject to Section 7.10 hereof, the successor corporation without
any further act shall be the successor Trustee.

<PAGE>
                                     -105-

                  (1) to comply with Section 5.01 hereof;

                  (2) to provide for uncertificated Notes in addition to or in

                  (3) to comply with any requirements of the Commission under

                  (4) to cure any ambiguity, defect or inconsistency, or to make

         materially and adversely affect the rights of any Noteholder;

                  (5) add Guarantors with respect to the Notes; or

                  (6) release Guarantors when permitted by this Indenture.

                  The Trustee is hereby authorized to join with the Issuers and
the Guarantors in the execution of any supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations which may be therein contained, but the Trustee
shall not be obligated to enter into any such supplemental indenture which
adversely affects its own rights, duties or immunities under this Indenture.

Section 8.02. With Consent of Holders.

                  The Issuers, the Guarantors and the Trustee may modify or
supplement this Indenture or the Notes with the written consent of the Holders
of not less than a majority in principal amount of the outstanding Notes without
notice to any Noteholder. The Holders of not less than a majority in aggregate
principal amount of the outstanding Notes may waive compliance in a particular
instance by the Issuers and the Guarantors with any provision of this Indenture
or the Notes without notice to any Noteholder. Subject to Section 8.04, without
the consent of each Noteholder affected, however, an amendment, supplement or
waiver, including a waiver pursuant to Section 6.04, may not:

                  (1) reduce the amount of Notes whose Holders must consent to
         an amendment, supplement or waiver to this Indenture or the Notes;
<PAGE>
                                     -106-

                  (2) reduce the rate of or change the time for payment of
         interest (including Additional Interest (as defined in the Registration
         Rights Agreement)) on any Note;

                  (3) reduce the principal of, or premium on, or change the
         stated maturity, of any Note or change the date on which any Notes may
         be subject to redemption or repurchase or reduce the redemption or
         repurchase price therefor;

                  (4) make any Note payable in money other than that stated in
         the Note or change the place of payment from New York, New York;

                  (5) waive a Default in the payment of the principal of, or
         interest on, or any redemption payment with respect to, any Note;

                  (6) make any changes in Sections 6.04 or 6.07 hereof or this
         sentence of Section 8.02;

                  (7) amend, change or modify in any material respect, the
         obligation of the Issuers to make and consummate a Change of Control
         Offer in the event of a Change of Control or, make and consummate an
         Excess Proceeds Offer with respect to any Asset Sale that has been
         consummated or modify any of the provisions or definitions with respect
         thereto;

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

                  (9) release any Guarantor other than Holdings from any of its
         obligations under its Guarantee or this Indenture otherwise than in
         accordance with the terms of this Indenture.

                  After an amendment, supplement or waiver under this Section
8.02 becomes effective, the Issuers shall mail to the Holders a notice briefly
describing the amendment, supplement or waiver.

                  Upon the request of the Issuers, accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the receipt by the Trustee of evidence reasonably satisfactory to the
Trustee of the consent of
<PAGE>
                                     -107-

the Noteholders as aforesaid and upon receipt by the Trustee of the documents
described in Section 8.06 hereof, the Trustee shall join with the Issuers and
the Guarantors in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture, in which case the Trustee may in its discretion, but shall
not be obligated to, enter into such supplemental indenture.

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

Section 8.03. Compliance with Trust Indenture Act.

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

Section 8.04. Revocation and Effect of Consents.

                  Until an amendment, supplement, waiver or other action becomes
effective, a consent to it by a Holder is a continuing consent conclusive and
binding upon such Holder and every subsequent Holder of the same Note or portion
thereof, and of any Note issued upon the transfer thereof or in exchange
therefor or in place thereof, even if notation of the consent is not made on any
such Note. Any such Holder or subsequent Holder, however, may revoke the consent
as to his Note or portion of a Note, if the Trustee receives the notice of
revocation before the date the amendment, supplement, waiver or other action
becomes effective.

                  The Issuers may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any
amendment, supplement, or waiver. If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent to such amendment, supplement, or waiver or to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date unless the consent of the requisite number
of Holders has been obtained.

                  After an amendment, supplement, waiver or other action becomes
effective, it shall bind every Noteholder, unless
<PAGE>
                                     -108-

it makes a change described in any of clauses (1) through (9) of Section 8.02
hereof. In that case the amendment, supplement, waiver or other action shall
bind each Holder who has consented to it and every subsequent Holder of a Note
or portion of a Note that evidences the same debt as the consenting Holder's
Note.

Section 8.05. Notation on or Exchange of Notes.

                  If an amendment, supplement, or waiver changes the terms of a
Note, the Trustee may request the Holder to deliver it to the Trustee. In such
case, the Trustee shall place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Issuers or the
Trustee so determine, the Issuers in exchange for the Note shall issue and the
Trustee shall authenticate a new Note that reflects the changed terms. 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 8.06. Trustee to Sign Amendments, etc.

                  The Trustee shall sign any amendment, supplement or waiver
authorized pursuant to this Article 8 if the amendment, supplement or waiver
does not materially adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it.
In signing or refusing to sign such amendment, supplement or waiver the Trustee
shall be entitled to receive and, subject to Section 7.01 hereof, shall be fully
protected in relying upon an Officers' Certificate and an Opinion of Counsel
stating that such amendment, supplement or waiver is authorized or permitted by
this Indenture. The Issuers and each Guarantor may not sign an amendment or
supplement until the Board of Directors of each of the Issuers and each such
Guarantor approves it.

of the Issuers,
<PAGE>
                                     -109-

         been replaced or paid as provided in Section 2.07 hereof and (B) Notes
         for whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Issuers and thereafter repaid to

         Trustee for cancellation; or

                  (b) (i) all such Notes not theretofore delivered to the
         Trustee for cancellation have become due and payable and the Issuers

         Government Obligations sufficient to pay and discharge the entire
         Indebtedness on such Notes not theretofore delivered to the Trustee for

at the expense of the Issuers, shall, subject to Section 9.06 hereof, execute

set forth in any such specified Section or portion thereof, whether directly or
indirectly by reason of any reference elsewhere herein to any such specified
Section or portion thereof or by reason of any reference in any such specified

                  to any rights of holders of Senior Indebtedness, including,
                  without limitation, those arising under this Indenture, and

                  is an "insider" (as such term is used under applicable
                  Bankruptcy Law) of any Issuer after the 91st day after the
                  date of such deposit or, if longer, ending on the day
                  following the expiration of the longest preference period
                  under any Bankruptcy Law applicable to the Issuers in respect
                  of such deposit, the funds deposited in trust will not be
                  subject to the effect of any Bankruptcy Law; and

                  (11) before or after a deposit, the Issuers may make
         arrangements satisfactory to the Trustee for the redemption of Notes at
         a future date in accordance with Section 3.07(a) hereof.

outstanding Notes.

                  Anything in this Article 9 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Issuers from time to time upon a written
request of the Issuers in the form of an Officers' Certificate any money or U.S.
Government Obligations held by it as provided in Section 9.01 or 9.04 hereof
which, in the opinion of a nationally-recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 9.06. Reinstatement.

                  If the Trustee or Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 9.01, 9.02 or 9.03 hereof
by reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Issuers' and each Guarantor's obligations under this
Indenture, the Notes and the Guarantees shall be revived and reinstated as
though no deposit had occurred pursuant to this Article 9 until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 9.01 hereof; provided, however, that if
the Issuers or the Guarantors have made any payment of principal of, premium, if
any, or accrued interest on any Notes because of the reinstatement of their
obligations, the Issuers and each such Guarantor shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money or
U.S. Government Obligations held by the Trustee or Paying Agent.

Section 9.07. Moneys Held by Paying Agent.

                  In connection with the satisfaction and discharge of this
Indenture, all moneys then held by any Paying Agent under the provisions of this
Indenture shall, upon demand of the Issuers, be paid to the Trustee, or if
sufficient moneys have been deposited pursuant to Section 9.01 hereof, to the
Issuers (or, if such moneys had been deposited by any Guarantor, to such
Guarantor) and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.
<PAGE>
                                     -115-

Section 9.08. Moneys Held by Trustee.

                  Any moneys deposited with the Trustee or any Paying Agent or
then held by the Issuers or any Guarantor in trust for the payment of the
principal of, or premium, if any, or interest on any Note that are not applied
but remain unclaimed by the Holder of such Note for two years after the date
upon which the principal of, or premium, if any, or interest on such Note shall
have respectively become due and payable shall be repaid to the Issuers (or, if
appropriate, the applicable Guarantor) upon a written request of the Issuers in
the form of an Officers' Certificate, or if such moneys are then held by the
Issuers or any Guarantor in trust, such moneys shall be released from such
trust; and the Holder of such Note entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Issuers and the
Guarantors for the payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money shall thereupon cease.


                                   ARTICLE 10

                                   GUARANTEES


Section 10.01. Guarantees.

                  Each Guarantor hereby unconditionally and irrevocably
guarantees, jointly and severally, to each Holder and to the Trustee on behalf
of the Holders and its successors and assigns (a) the due and punctual payment
of principal of, premium, if any, and interest on the Notes when due, whether at
maturity, by acceleration, by redemption or otherwise, and all other monetary
obligations of the Issuers under this Indenture, the Notes and the Registration
Rights Agreement and (b) the full and punctual performance within applicable
grace periods of all other obligations of the Issuers under this Indenture, the
Notes and the Registration Rights Agreement (all the foregoing being hereinafter
collectively called the "Guaranteed Obligations"). Each Guarantor further agrees
that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice or further assent from such Guarantor and that such Guarantor
will remain bound under this Article 10 notwithstanding any extension or renewal
of any Guaranteed Obligation.

                  Each Guarantor waives diligence, presentment, demand of
payment, filing of claims with a court in the event of in-
<PAGE>
                                     -116-

solvency or bankruptcy of any Issuer, any right to require a proceeding first
against the Issuer, protest, notice and all demands whatsoever. Each Guarantor
waives notice of any default under the Notes or the Guaranteed Obligations. The
obligations of each Guarantor hereunder shall not be affected by (a) the failure
of any Holder or the Trustee to assert any claim or demand or to enforce any
right or remedy against the Company or any other Person under this Indenture,
the Notes or any other agreement or otherwise; (b) any extension or renewal of
any thereof; (c) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Notes or any other agreement; (d) the
release of any security held by any Holder or the Trustee for the Guaranteed
Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Guaranteed
Obligations; or (f) except as provided in Section 10.06, any change in the
ownership of such Guarantor.

                  Except as expressly set forth in Sections 10.02 and 10.06, the
obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason, including any claim of
waiver, release, surrender, alteration or compromise, and shall not be subject
to any defense of setoff, counterclaim, recoupment or termination whatsoever or
by reason of the invalidity, illegality or unenforceability of the Guaranteed
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or
otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture, the Notes or any
other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, willful or otherwise, in the performance of the Guaranteed
Obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
such Guarantor or would otherwise operate as a discharge of such Guarantor as a
matter of law or equity.

                  Each Guarantor further agrees that its Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of, premium, if any, or interest on
any Guaranteed Obligation is rescinded or must otherwise be restored by any
Holder or the Trustee upon the bankruptcy or reorganization of any Issuer or
otherwise.
<PAGE>
                                     -117-

                  In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of any Issuer to pay the principal
of, premium, if any, or interest on any obligation under the Notes or this
Indenture when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any other
obligation under the Notes or this Indenture, each Guarantor hereby promises to
and will, upon receipt of written demand by the Trustee, forthwith pay, or cause
to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of
(i) the unpaid amount of such Guaranteed Obligations, (ii) accrued and unpaid
interest on such Guaranteed Obligations (but only to the extent not prohibited
by law) and (iii) all other monetary Guaranteed Obligations of the Issuers to
the Holders and the Trustee.

                  Each Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any Guaranteed Obligations guaranteed hereby
until payment in full of all Guaranteed Obligations. Each Guarantor further
agrees that, as between it, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the Guaranteed Obligations hereby may be
accelerated as provided in Section 6 for the purposes of such Guarantor's
Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations under the Notes or
this Indenture guaranteed hereby, and (y) in the event of any declaration of
acceleration of such obligations as provided in Section 6, such obligations
(whether or not due and payable) shall forthwith become due and payable by such
Guarantor for the purposes of this Section.

                  Each Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Article 10.

Section 10.02. Limitation on Liability.

                  Any term or provision of this Indenture to the contrary
notwithstanding, the maximum aggregate amount of the obligations guaranteed
hereunder by any Guarantor shall not exceed the maximum amount that can be
hereby guaranteed without rendering this Indenture, as it relates to such
Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.
To effectuate the foregoing intention,
<PAGE>
                                     -118-

the obligations of each Guarantor shall be limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under its Guarantee or pursuant to its contribution obligations
hereunder, result in the obligations of such Guarantor under its Guarantee not
constituting a fraudulent conveyance or fraudulent transfer under federal or
state law. Each Guarantor that makes a payment or distribution under a Guarantee
shall be entitled to a contribution from each other Guarantor in a pro rata
amount based on the Adjusted Net Assets of each Guarantor.

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

Section 10.03. Successors and Assigns.

                  This Article 10 shall be binding upon each Guarantor and its
successors and assigns and shall enure to the benefit of the successors and
assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

Section 10.04. No Waiver.

                  Neither a failure nor a delay on the part of either the
Trustee or the Holders in exercising any right, power or privilege under this
Article 10 shall operate as a waiver thereof, nor shall a single or partial
exercise thereof preclude any other or further exercise of any right, power or
privilege. The rights, remedies and benefits of the Trustee and the Holders
herein expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article 10 at law, in
equity, by statute or otherwise.

Section 10.05. Modification.

                  No modification, amendment or waiver of any provision of this
Article 10, nor the consent to any departure by any
<PAGE>
                                     -119-

Guarantor therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in the same, similar or other
circumstances.

Section 10.06. Release of Guarantor.

                  A Guarantor shall be released from all of its obligations
under its Guarantee if:

                   (i) the Guarantor has sold all or substantially all of its
         assets or the Company and its Restricted Subsidiaries have sold all of
         the Capital Stock of the Guarantor owned by them, in each case in a
         transaction in compliance with Sections 4.09 and 5.01 hereof; or

                  (ii) the Guarantor merges with or into or consolidates with,
         or transfers all or substantially all of its assets to, the Company or
         another Guarantor in a transaction in compliance with Section 5.01
         hereof;

and in each such case, such Guarantor has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with.

Section 10.07. Execution of Supplemental Indenture for Future Guarantors.

                  Each Subsidiary which is required to become a Guarantor
pursuant to Section 4.22 shall, and the Issuers shall cause each such Subsidiary
to, promptly execute and deliver to the Trustee a supplemental indenture in the
form of Exhibit F hereto pursuant to which such Subsidiary shall become a
Guarantor under this Section 10 and shall guarantee the obligations of the
Company under the Notes and this Indenture. Concurrently with the execution and
delivery of such supplemental indenture, the Company shall deliver to the
Trustee an Opinion of Counsel to the effect that such supplemental indenture has
been duly authorized, executed and delivered by such Subsidiary and that,
subject to the application of bankruptcy, insolvency, moratorium, fraudulent
conveyance or transfer and other similar laws relating to creditors' rights
generally and to the principles of equity, whether considered in a proceeding at
law or in equity, the Guarantee of such Guarantor is a legal, valid and
<PAGE>
                                     -120-

binding obligation of such Guarantor, enforceable against such Guarantor in
accordance with its terms.

Section 10.08. Execution and Delivery of Guarantees.

                  To evidence the Guarantee set forth in this Article 10, each
Guarantor hereby agrees that a notation of such Guarantee substantially in the
form of Exhibit E hereto shall be placed on each Note authenticated and made
available for delivery by the Trustee and that this Guarantee shall be executed
on behalf of each Guarantor by the manual or facsimile signature of two Officers
or an Officer and the Secretary of each Guarantor.

                  Each Guarantor hereby agrees that the Guarantee set forth in
Section 10.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Guarantee.

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

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

Section 10.09. Guarantee Obligations Subordinated to Guarantor Senior
               Indebtedness.

                  Each Guarantor covenants and agrees, and each Holder, by its
acceptance thereof, likewise covenants and agrees, that to the extent and in the
manner hereinafter set forth in this Article 10, the Indebtedness represented by
the Guarantee and the payment of all Obligations on the Notes pursuant to the
Guarantee by such Guarantor are hereby expressly made subordinate in right of
payment as provided in this Article 10 to the prior indefeasible payment and
satisfaction in full in cash of all Obligations in respect of all Guarantor
Senior Indebtedness of such Guarantor (including post-petition interest
thereon).

                  This Section 10.09 and the following Sections 10.10 through
10.14 are for the benefit of, and shall be enforceable directly by, the holders
of Guarantor Senior Indebtedness, each holder is made an obligee hereunder, and
each holder of any Guarantor Senior Indebtedness, whether now outstanding or
here-
<PAGE>
                                     -121-

after created, incurred, assumed or guaranteed, shall be deemed to have
acquired such Guarantor Senior Indebtedness in reliance upon the covenants and
provisions contained in this Indenture and the Notes.

Section 10.10. Payment Over of Proceeds upon Dissolution, etc., of a Guarantor.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, relative to any Guarantor or to its
creditors, as such, or to its assets, whether voluntary or involuntary, or (b)
any liquidation, dissolution or other winding-up of any Guarantor, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy
or (c) any general assignment for the benefit of creditors or any other
marshaling of assets or liabilities of any Guarantor, then and in any such
event:

                  (1) the holders of all Guarantor Senior Indebtedness of such
         Guarantor shall be entitled to receive indefeasible payment and
         satisfaction in full in cash, of all amounts due on or in respect of
         all such Guarantor Senior Indebtedness (including interest after the
         commencement of any such proceeding at the rate specified in the
         applicable Guarantor Senior Indebtedness, whether or not an allowed
         claim), of such Guarantor before the Holders are entitled to receive or
         retain, pursuant to the Guarantee of such Guarantor, any payment or
         distribution of any kind or character (other than payment or
         distribution from the trust described in Section 9.04) by such
         Guarantor on account of any of the Guaranteed Obligations; and

                  (2) any payment or distribution of assets of such Guarantor of
         any kind or character, whether in cash, Property or securities, by
         set-off or otherwise, to which the Holders or the Trustee would be
         entitled but for the subordination provisions of this Article 10 shall
         be paid by the liquidating trustee or agent or other Person making such
         payment or distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the holders of Guarantor
         Senior Indebtedness of such Guarantor or their representative or
         representatives or to the trustee or trustees under any indenture under
         which any instruments evidencing any of such Guarantor Senior
         Indebtedness may have been issued, ratably according to the aggregate
         amounts remaining unpaid on account of such Guarantor Senior
         Indebtedness held or rep-
<PAGE>
                                     -122-

         resented by each, to the extent necessary to make indefeasible payment
         in full in cash of all such Guarantor Senior Indebtedness remaining
         unpaid, after giving effect to any concurrent payment or distribution
         to the holders of such Guarantor Senior Indebtedness; and

                  (3) in the event that, notwithstanding the foregoing
         provisions of this Section 10.10, the Trustee or any Holder shall have
         received any payment or distribution of assets of such Guarantor of any
         kind or character, whether in cash, Property or securities, including,
         without limitation, by way of set-off or otherwise, in respect of any
         of the Guaranteed Obligations before all Guarantor Senior Indebtedness
         of such Guarantor is indefeasibly paid in full, then and in such event
         such payment or distribution shall be held in trust for the benefit of
         and shall be paid over or delivered forthwith to the trustee in
         bankruptcy, receiver, liquidating trustee, custodian, assignee, agent
         or other Person making payment or distribution of assets of such
         Guarantor for application to the payment of all such Guarantor Senior
         Indebtedness remaining unpaid, to the extent necessary to pay all of
         such Guarantor Senior Indebtedness in full in cash, Cash Equivalents
         or, as acceptable to the holders of such Guarantor Senior Indebtedness,
         any other manner, after giving effect to any concurrent payment or
         distribution to or for the holders of such Guarantor Senior
         Indebtedness.

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

                  The consolidation of a Guarantor with, or the merger of a
Guarantor with or into, another Person or the liquidation or dissolution of a
Guarantor following the conveyance, transfer or lease of its properties and
assets substantially as an entirety to another Person upon the terms and
conditions set forth in Article 5 hereof shall not be deemed a dissolution,
<PAGE>
                                     -123-

winding-up, liquidation, reorganization, assignment for the benefit of creditors
or marshaling of assets and liabilities of such Guarantor for the purposes of
this Article 10 if the Person formed by such consolidation or the surviving
entity of such merger or the Person which acquires by conveyance, transfer or
lease such properties and assets substantially as an entirety, as the case may
be, shall, as a part of such consolidation, merger, conveyance, transfer or
lease, comply with the conditions set forth in such Article 5 hereof.

Section 10.11. Suspension of Guaranteed Obligations When Guarantor Senior
               Indebtedness in Default.

                  (a) Unless Section 10.10 hereof shall be applicable, after the
occurrence of a Payment Default no payment or distribution (other than a payment
or distribution from the trust described in Section 9.04) of any kind or
character (including, without limitation, cash, Property and any payment or
distribution which may be payable or deliverable by reason of the payment of any
other Indebtedness of such Guarantor being subordinated to its Guaranteed
Obligations) may be made by or on behalf of such Guarantor (or any Subsidiary of
such Guarantor), including, without limitation, by way of set-off or otherwise,
for or on account of the Notes or its Guaranteed Obligations, and neither the
Trustee nor any Holder shall take or receive from any Guarantor (or any
Subsidiary of such Guarantor), directly or indirectly in any manner, payment in
respect of all or any portion of the Notes or its Guaranteed Obligations
commencing on the date of the receipt by the Trustee of written notice from the
representative of the holders of Guarantor Senior Indebtedness (the "Guarantor
Representative") of the occurrence of a Payment Default, and in any such event,
such prohibition shall continue until such Payment Default is cured, waived in
writing or ceases to exist. At such time as the prohibition set forth in the
preceding sentence shall no longer be in effect, subject to the provisions of
the following paragraph (b), such Guarantor shall resume making any and all
required payments in respect of the Guaranteed Obligations.

                  (b) Unless Section 10.10 hereof shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
of any Guarantor, no payment or distribution (other than a payment or
distribution made from the trust described in Section 9.04) of any assets of
such Guarantor of any kind or character (including, without limitation, cash,
Property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other Indebtedness of such Guarantor being
subordinated to its Guar-
<PAGE>
                                     -124-

anteed Obligations) shall be made by such Guarantor, including, without
limitation, by way of set-off or otherwise, for or on account of the Notes or
any of its Guaranteed Obligations or any Obligations under the Notes, the
Registration Rights Agreement or this Indenture, or for or on account of the
purchase, redemption or other acquisition of any Notes and neither the Trustee
nor any Holder shall take or receive from such Guarantor, directly or indirectly
in any manner, payment in respect of all or any portion of the Guaranteed
Obligations or any Obligations under the Notes, the Registration Rights
Agreement or this Indenture, or for or on account of the purchase, redemption or
other acquisition of any Notes for a period (the "Guarantee Payment Blockage
Period") commencing on the date of receipt by the Trustee of written notice from
the Guarantor Representative of such Non-Payment Event of Default, unless and
until (subject to any blockage of payments that may then be in effect under the
preceding paragraph (a)) the earliest to occur of the following events: (w) more
than 179 days shall have elapsed since the date of receipt of such written
notice by the Trustee, (x) such Non-Payment Event of Default shall have been
cured or waived in writing or shall have ceased to exist, (y) such Designated
Senior Indebtedness shall have been indefeasibly paid in full in cash or (z)
such Guarantee Payment Blockage Period shall have been terminated by written
notice to such Guarantor or the Trustee from the Guarantor Representative, after
which, in the case of clause (w), (x), (y) or (z), such Guarantor shall resume
making any and all required payments in respect of the Guaranteed Obligations.
Notwithstanding any other provisions of this Indenture, in no event shall a
Guarantee Payment Blockage Period extend beyond 179 days from the date of the
receipt by the Trustee of the notice referred to in this Section 10.11(b) or, in
the event of a Non-Payment Event of Default which formed the basis for a Payment
Blockage Period under Section 11.03(b) hereof, 179 days from the date of the
receipt by the Trustee of the notice referred to in Section 11.03(b) (the
"Initial Guarantee Blockage Period"). Any number of additional Guarantee Payment
Blockage Periods may be commenced during the Initial Guarantee Blockage Period;
provided, however, that no such additional Guarantee Payment Blockage Period
shall extend beyond the Initial Guarantee Blockage Period. After the expiration
of the Initial Guarantee Blockage Period, no Guarantee Payment Blockage Period
may be commenced under this Section 10.11(b) and no Payment Blockage Period may
be commenced under Section 11.03(b) hereof until at least 180 consecutive days
have elapsed from the last day of the Initial Guarantee Blockage Period.
Notwithstanding any other provisions of this Indenture, no Non-Payment Event of
Default with respect to Designated Senior Indebtedness which existed or was
<PAGE>
                                     -125-

continuing on the date of the commencement of any Guarantee Payment Blockage
Period initiated by the Guarantor Representative shall be, or be made, the basis
for the commencement of a second Guarantee Payment Blockage Period initiated by
the Guarantor Representative unless such Non-Payment Event of Default shall have
been cured or waived for a period of not less than 90 consecutive days.
Notwithstanding the foregoing, if the obligations of the Issuers under the Notes
have been accelerated pursuant to Article 6 of this Indenture or otherwise, the
Trustee shall be deemed to have received notice from the Guarantor
Representative of a Non-Payment Event of Default relating to such acceleration
as provided for in the first sentence of this clause (b).

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or any Holder receives any payment or distribution of assets of such
Guarantor of any kind, whether in cash, Property or securities, including,
without limitation, by way of set-off or otherwise, in respect of the Guaranteed
Obligations, before all Guarantor Senior Indebtedness of such Guarantor is
indefeasibly paid and satisfied in full in cash, then such payment or
distribution (other than a payment or distribution from the trust described in
Section 9.04) will be held by the recipient in trust for the benefit of holders
of Guarantor Senior Indebtedness and will be immediately paid over or delivered
to the holders of Guarantor Senior Indebtedness or their representative or
representatives to the extent necessary to make a payment in full of all
Guarantor Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution, or provision therefor, to or for the holders
of Guarantor Senior Indebtedness.

Section 10.12. Subrogation to Rights of Holders of Guarantor Senior
               Indebtedness.

                  Upon the payment in full of all amounts payable under or in
respect of all Guarantor Senior Indebtedness of a Guarantor, the Holders shall
be subrogated to the rights of the holders of such Guarantor Senior Indebtedness
to receive payments and distributions of cash, Property and securities of such
Guarantor made on such Guarantor Senior Indebtedness until all amounts due to be
paid under the Guarantee shall be paid in full. For the purposes of such
subrogation, no payments or distributions to holders of Guarantor Senior
Indebtedness of any cash, Property or securities to which Holders or the Trustee
would be entitled except for the provisions of this Article 10, and no payments
over pursuant to the provisions of this Article 10 to holders of Guarantor
Senior Indebtedness by Holders

                                     -126-

or the Trustee, shall, as among each Guarantor, its creditors other than holders
of Guarantor Senior Indebtedness and the Holders, be deemed to be a payment or
distribution by such Guarantor to or on account of such Guarantor Senior
Indebtedness.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 10 shall
have been applied, pursuant to the provisions of this Article 10, to the payment
of all amounts payable under Guarantor Senior Indebtedness, then and in such
case, the Holders shall be entitled to receive from the holders of such
Guarantor Senior Indebtedness at the time outstanding any payments or
distributions received by such holders of Guarantor Senior Indebtedness in
excess of the amount sufficient to pay all amounts payable under or in respect
of such Guarantor Senior Indebtedness in full in cash.

Section 10.13. Guarantee Subordination Provisions Solely to Define Relative
               Rights.

                  The subordination provisions of this Article 10 are and are
intended solely for the purpose of defining the relative rights of the Holders
on the one hand and the holders of Guarantor Senior Indebtedness on the other
hand. Nothing contained in this Article 10 or elsewhere in this Indenture or in
the Notes is intended to or shall (a) impair, as among each Guarantor, its
creditors other than holders of its Guarantor Senior Indebtedness and the
Holders, the obligation of such Guarantor, which is absolute and unconditional,
to make payments to the Holders in respect of the Guaranteed Obligations in
accordance with its terms; or (b) affect the relative rights against such
Guarantor of the Holders and creditors of such Guarantor other than the holders
of the Guarantor Senior Indebtedness; or (c) prevent the Trustee or any Holder
from exercising all remedies otherwise permitted by applicable law upon a
Default or an Event of Default under this Indenture, subject to the rights, if
any, under this Article 10 of the holders of Guarantor Senior Indebtedness (1)
in any case, proceeding, dissolution, liquidation or other winding-up,
assignment for the benefit of creditors or other marshaling of assets and
liabilities of the Issuers referred to in Section 10.10 hereof, to receive,
pursuant to and in accordance with such Section, cash, Property and securities
otherwise payable or deliverable to the Trustee or such Holder, or (2) under the
conditions specified in Section 10.11 hereof, to prevent any payment prohibited
by such Section or enforce their rights pursuant to Section 10.11(c) hereof.
<PAGE>
                                     -127-

                  The failure by any Guarantor to make a payment in respect of
its obligations on its Guarantee by reason of any provision of this Article 10
shall not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

Section 10.14. Application of Certain Article 11 Provisions.

                  The provisions of Sections 11.04, 11.07, 11.08, 11.09, 11.10,
11.12 and 11.13 hereof shall apply, mutatis mutandis, to each Guarantor and
their respective holders of Guarantor Senior Indebtedness and the rights, duties
and obligations set forth therein shall govern the rights, duties and
obligations of each Guarantor, the holders of Guarantor Senior Indebtedness, the
Holders and the Trustee with respect to the Guarantee and all references therein
to Article 11 hereof shall mean this Article 10.


                                   ARTICLE 11

                             SUBORDINATION OF NOTES


Section 11.01. Notes Subordinate to Senior Indebtedness.

                  The Issuers covenant and agree, and each Holder, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article 11, the Indebtedness
represented by the Notes and the payment of all Obligations on the Notes are
hereby expressly made subordinate in right of payment as provided in this
Article 11 to the prior indefeasible payment and satisfaction in full in cash of
all Obligations in respect of all Senior Indebtedness (including post-petition
interest thereon).

                  The provisions of this Article 11 are for the benefit of, and
shall be enforceable directly by, the holders of Senior Indebtedness of each
Issuer, each holder is made an obligee hereunder, and each holder of Senior
Indebtedness of an Issuer whether now outstanding or hereafter created,
incurred, assumed or guaranteed shall be deemed to have acquired Senior
Indebtedness of such Issuer in reliance upon the covenants and provisions
contained in this Indenture and the Notes.

Section 11.02. Payment Over of Proceeds upon Dissolution, etc.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, relative to any Issuer or to its
creditors, as such, or to its assets, whether voluntary or involuntary or (b)
any liquidation, dissolution or other winding-up of any Issuer, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy,
or (c) any general assignment for the benefit of creditors or any other
marshalling of assets or liabilities of any Issuer, then and in any such event:

                  (1) the holders of Senior Indebtedness of such Issuer shall be
         entitled to receive indefeasible payment and satisfaction in full in
         cash of all amounts due on or in respect of all Senior Indebtedness
         (including interest after the commencement of any such proceeding at
         the rate specified in the applicable Senior Indebtedness, whether or
         not an allowed claim), of such Issuer before the Holders are entitled
         to receive or retain any payment or distribution of any kind or
         character (other than a payment or distribution from the trust
         described in Section 9.04) on account of the Notes or any Obligations
         on the Notes, the Registration Rights Agreement or this Indenture; and

                  (2) any payment or distribution of assets of any Issuer of any
         kind or character, whether in cash, Property or securities, by set-off
         or otherwise, to which the Holders or the Trustee would be entitled but
         for the provisions of this Article 11 shall be paid by the liquidating
         trustee or agent or other Person making such payment or distribution,
         whether a trustee in bankruptcy, a receiver or liquidating trustee or
         otherwise, directly to the holders of Senior Indebtedness or their
         representative or representatives or to the trustee or trustees under
         any indenture under which any instruments evidencing any of such Senior
         Indebtedness may have been issued, ratably according to the aggregate
         amounts remaining unpaid on account of the Senior Indebtedness held or
         represented by each, to the extent necessary to make indefeasible
         payment in full in cash of all Senior Indebtedness remaining unpaid,
         after giving effect to any concurrent payment or distribution, to the
         holders of such Senior Indebtedness; and
<PAGE>
                                     -129-

                  (3) in the event that, notwithstanding the foregoing
         provisions of this Section 11.02, the Trustee or any Holder shall have
         received any payment or distribution of assets of the Issuers of any
         kind or character, whether in cash, Property or securities, including,
         without limitation, by way of set-off or otherwise, in respect of
         principal of, premium, if any, and interest on the Notes before all
         Senior Indebtedness is indefeasibly paid in full, then and in such
         event such payment or distribution shall be held in trust for the
         benefit of and shall be paid over or delivered forthwith to the trustee
         in bankruptcy, receiver, liquidating trustee, custodian, assignee,
         agent or other Person making payment or distribution of assets of the
         Issuers for application to the payment of all Senior Indebtedness
         remaining unpaid, to the extent necessary to pay all Senior
         Indebtedness in full in cash, Cash Equivalents or, as acceptable to the
         holders of Senior Indebtedness, any other manner, after giving effect
         to any concurrent payment or distribution, to or for the holders of
         Senior Indebtedness.

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

                  The consolidation of the Company with, or the merger of the
Company with or into, another Person or the liquidation or dissolution of the
Company following the conveyance, transfer or lease of its properties and assets
substantially as an entirety to another Person upon the terms and conditions set
forth in Article 5 hereof shall not be deemed a dissolution, winding-up,
liquidation, reorganization, assignment for the benefit of creditors or
marshaling of assets and liabilities of the Company for the purposes of this
Article 11 if the Person formed by such consolidation or the surviving entity of
such merger or the Person which acquires by conveyance, transfer or lease such
properties and assets substantially as an entirety, as the case may be, shall,
as a part of such consolidation,

                                     -130-

merger, conveyance, transfer or lease, comply with the conditions set forth in
such Article 5 hereof.

Section 11.03. Suspension of Payment When Senior Indebtedness in Default.

                  (a) Unless Section 11.02 hereof shall be applicable, after the
occurrence of a Payment Default no payment or distribution (other than a payment
or distribution from the trust described in Section 9.04) of any kind or
character (including, without limitation, cash, Property and any payment or
distribution which may be payable or deliverable by reason of the payment of any
other Indebtedness of any Issuer being subordinated to the payment of the Notes
by such Issuer) may be made by or on behalf of such Issuer or any Subsidiary of
such Issuer, including, without limitation, by way of set-off or otherwise, for
or on account of the Notes or of any Obligations under the Notes, the
Registration Rights Agreement or this Indenture, or for or on account of the
purchase, redemption or other acquisition of any Notes, and neither the Trustee
nor any Holder shall take or receive from such Issuer or any Subsidiary of such
Issuer, directly or indirectly in any manner, payment in respect of all or any
portion of Notes or of any Obligations under the Notes, the Registration Rights
Agreement or this Indenture, or for or on account of the purchase, redemption or
other acquisition of any Notes commencing on the date of receipt by the Trustee
of written notice from the representa-tive of the holders of Designated Senior
Indebtedness (the "Representative") of the occurrence of a Payment Default, and
in any such event, such prohibition shall continue until such Payment Default is
cured, waived in writing or ceases to exist. At such time as the prohibition set
forth in the preceding sentence shall no longer be in effect, subject to the
provisions of the following paragraph (b), such Issuer shall resume making any
and all required payments in respect of the Notes, including any missed
payments.

                  (b) Unless Section 11.02 hereof shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness,
no payment or distribution (other than a payment or distribution from the trust
described in Section 9.04) of any assets of any Issuer of any kind or character
(including, without limitation, cash, Property and any payment or distribution
which may be payable or deliverable by reason of the payment of any other
Indebtedness of any Issuer being subordinated to the payment of the Notes by
such Issuer) shall be made by any Issuer or any Restricted Subsidiary of such
Issuer, including, without limitation, by way of set-off or oth-
<PAGE>
                                     -131-

erwise, for or on account of the Notes or of any Obligations under the Notes,
the Registration Rights Agreement or this Indenture or on account of the
purchase, redemption or other acquisition of Notes, and neither the Trustee nor
any Holder shall take or receive from such Issuer or Restricted Subsidiary of
such Issuer, directly or indirectly in any manner, payment in respect of all or
any portion of the Notes or any Obligations under the Notes, the Registration
Rights Agreement or the Indenture for a period ("Payment Blockage Period")
commencing on the date of receipt by the Trustee of written notice from the
Representative of such Non-Payment Event of Default unless and until (subject to
any blockage of payments that may then be in effect under the preceding
paragraph (a)) the earliest to occur of the following events: (w) more than 179
days shall have elapsed since the date of receipt of such written notice by the
Trustee, (x) such Non-Payment Event of Default shall have been cured or waived
in writing or shall have ceased to exist, (y) such Designated Senior
Indebtedness shall have been indefeasibly paid in full in cash or (z) such
Payment Blockage Period shall have been terminated by written notice to the
Issuers or the Trustee from the Representative after which, in the case of
clause (w), (x), (y) or (z), such Issuers shall resume making any and all
required payments in respect of the Notes, including any missed payments.
Notwithstanding any other provisions of this Indenture, in no event shall a
Payment Blockage Period extend beyond 179 days from the date of the receipt by
the Trustee of the notice referred to in this Section 11.03(b) (the "Initial
Blockage Period"). Any number of additional Payment Blockage Periods may be
commenced during the Initial Blockage Period; provided, however, that no such
additional Payment Blockage Period shall extend beyond the Initial Blockage
Period. After the expiration of the Initial Blockage Period, no Payment Blockage
Period may be commenced under this Section 11.03(b) and no Guarantee Payment
Blockage Period may be commenced under Section 10.11(b) hereof until at least
180 consecutive days have elapsed from the last day of the Initial Blockage
Period. Notwithstanding any other provisions of this Indenture, no Non-Payment
Event of Default with respect to Designated Senior Indebtedness which existed or
was continuing on the date of the commencement of any Payment Blockage Period
initiated by the Representative shall be, or be made, the basis for the
commencement of a second Payment Blockage Period initiated by the Representative
unless such event of default shall have been cured or waived for a period of not
less than 90 consecutive days. Notwithstanding the foregoing, if the obligations
of the Issuers under the Notes have been accelerated pursuant to Article 6 of
this Indenture or otherwise, the Trustee shall be deemed to have received notice
from the Representative
<PAGE>
                                     -132-

of a Non-Payment Event of Default relating to such acceleration as provided for
in the first sentence of this clause (b).

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or any Holder receives any payment or distribution of assets of such
Issuer of any kind, whether in cash, Property or securities, including, without
limitation, by way of set-off or otherwise, in respect of the Notes or any
Obligations under the Notes, the Registration Rights Agreement or the Indenture,
before all Senior Indebtedness of such Issuer is indefeasibly paid and satisfied
in full in cash, then such payment or distribution (other than a payment or
distribution from the trust described in Section 9.04) will be held by the
recipient in trust for the benefit of holders of Senior Indebtedness and will be
immediately paid over or delivered to the holders of Senior Indebtedness or
their representative or representatives to the extent necessary to make payment
in full of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution, or provision therefor, to or for the holders
of Senior Indebtedness.

Section 11.04. Trustee's Relation to Senior Indebtedness.

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article 11, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and the
Trustee shall not be liable to any holder of Senior Indebtedness (other than for
its willful misconduct or negligence) if it shall mistakenly pay over or deliver
to Holders, any Issuer or any other Person moneys or assets to which any holder
of Senior Indebtedness shall be entitled by virtue of this Article 11 or
otherwise. Nothing in this Section 11.04 shall affect the obligation of any
other such Person receiving such payment or distribution from the Trustee or any
other Agent to hold such payment for the benefit of, and to pay such payment
over to, the holders of Senior Indebtedness.

Section 11.05. Subrogation of Rights of Holders of Senior Indebtedness.

                  Upon the payment in full of all Senior Indebtedness, the
Holders shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, Property and
securities applicable to the Senior In-
<PAGE>
                                     -133-

debtedness until the principal of, premium, if any and interest on the Notes
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of Senior Indebtedness of any cash, Property or
securities to which the Holders or the Trustee would be entitled except for the
provisions of this Article 11, and no payments over pursuant to the provisions
of this Article 11 to the holders of Senior Indebtedness by Holders or the
Trustee, shall, as among any Issuer, its creditors other than holders of Senior
Indebtedness and the Holders, be deemed to be a payment or distribution by such
Issuer to or on account of the Senior Indebtedness.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 11 shall
have been applied, pursuant to the provisions of this Article 11, to the payment
of all amounts payable under the Senior Indebtedness of any Issuer, then and in
such case the Holders shall be entitled to receive from the holders of such
Senior Indebtedness at the time outstanding any payments or distributions
received by such holders of such Senior Indebtedness in excess of the amount
sufficient to pay all amounts payable under or in respect of such Senior
Indebtedness in full in cash.

Section 11.06. Provisions Solely to Define Relative Rights.

                  The provisions of this Article 11 are and are intended solely
for the purpose of defining the relative rights of the Holders on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article 11 or elsewhere in this Indenture or in the Notes is intended to or
shall (a) impair, as among any Issuer, its creditors other than holders of
Senior Indebtedness and the Holders, the obligation of the Issuers, which is
absolute and unconditional, to pay to the Holders the principal of, premium, if
any, and interest on the Notes as and when the same shall become due and payable
in accordance with their terms; or (b) affect the relative rights against the
Issuers of the Holders and creditors of the Issuers other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or any Holder from exercising
all remedies otherwise permitted by applicable law upon a Default or an Event of
Default under this Indenture, subject to the rights, if any, under this Article
11 of the holders of Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Issuers referred
to in Section 11.02 hereof,
<PAGE>
                                     -134-

to receive, pursuant to and in accordance with such Section, cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder, or
(2) under the conditions specified in Section 11.03, to prevent any payment
prohibited by such Section or enforce their rights pursuant to Section 11.03(c)
hereof.

                  The failure to make a payment on account of principal of,
premium, if any, or interest on the Notes by reason of any provision of this
Article 11 shall not be construed as preventing the occurrence of a Default or
an Event of Default hereunder.

Section 11.07. Trustee to Effectuate Subordination.

                  Each Holder of a Note by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of any Issuer whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the timely filing of a claim for the unpaid balance
of the indebtedness of any Issuer owing to such Holder in the form required in
such proceedings and the causing of such claim to be approved. If the Trustee
does not file such a claim prior to 30 days before the expiration of the time to
file such a claim, the holders of Senior Indebtedness, or any Representative, is
hereby authorized to have the right to file such a claim for and on behalf of
the Holders, and the Trustee shall, upon written request, supply such holders
and Representative all information and copies of documents within the Trustee's
possession and relating to the Notes or the Issuers which such holders or
Representatives reasonably request in order to file such claims.

Section 11.08. No Waiver of Subordination Provisions.

                  (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
any Issuer or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by any Issuer with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.
<PAGE>
                                     -135-

                  (b) Without limiting the generality of subsection (a) of this
Section 11.08, the holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article 11 or the obligations hereunder of the
Holders to the holders of Senior Indebtedness, do any one or more of the
following: (1) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior Indebtedness or otherwise amend or
supplement in any manner Senior Indebtedness of any Issuer or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding; (2) sell, exchange, release or otherwise deal with any Property
pledged, mortgaged or otherwise securing Senior Indebtedness; (3) release any
Person liable in any manner for the collection or payment of Senior
Indebtedness; and (4) exercise or refrain from exercising any rights against the
Issuers and any other Person; provided, however, that in no event shall any such
actions limit the right of the Holders to take any action to accelerate the
maturity of the Notes pursuant to Article 6 hereof or to pursue any rights or
remedies hereunder or under applicable laws if the taking of such action does
not otherwise violate the terms of this Indenture.

Section 11.09. Notice to Trustee.

                  (a) The Issuers shall give prompt written notice to the
Trustee of any fact known to the Issuers which would prohibit the making of any
payment to or by the Trustee at its Corporate Trust Office in respect of the
Notes. Notwithstanding the provisions of this Article 11 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee in respect of the Notes, unless and until the Trustee shall have
received written notice thereof from the Issuers or a holder of Senior
Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
this Section 11.09, shall be entitled in all respects to assume that no such
facts exist; provided, however, that if the Trustee shall not have received the
notice provided for in this Section 11.09 in accordance with Section 12.02 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose under this Indenture (including,
without limitation, the payment of the principal of, premium, if any, or
interest on any Note), then, anything herein contained to the contrary
notwithstanding
<PAGE>
                                     -136-

but without limiting the rights and remedies of the holders of
Senior Indebtedness or any trustee, fiduciary or agent therefor, the Trustee
shall have full power and authority to receive such money and to apply the same
to the purpose for which such money was received and shall not be affected by
any notice in accordance with Section 12.02 to the contrary which may be
received by it within two Business Days prior to such date; nor shall the
Trustee be charged with knowledge of the curing of any such default or the
elimination of the act or condition preventing any such payment unless and until
the Trustee shall have received an Officers' Certificate to such effect.

                  (b) Subject to the provisions of Section 7.01 hereof, the
Trustee shall be entitled to rely on the delivery to it of a written notice to
the Trustee and the Issuers by a Person representing itself to be a holder of
Senior Indebtedness (or a trustee, fiduciary or agent therefor) to establish
that such notice has been given by a holder of Senior Indebtedness (or a
trustee, fiduciary or agent therefor); provided, however, that failure to give
such notice to the Issuers shall not affect in any way the ability of the
Trustee to rely on such notice. In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 11, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

Section 11.10. Reliance on Judicial Order or Certificate of Liquidating Agent.

                  Upon any payment or distribution of assets of the Issuers
referred to in this Article 11, the Trustee, subject to the provisions of
Section 7.01 hereof, and the Holders shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding-up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
de-

livered to the Trustee or to the Holders, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other Indebtedness of any Issuer, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 11; provided that the foregoing shall
apply only if such court has been fully apprised of the provisions of this
Article 11.

Section 11.11. Rights of Trustee as a Holder of Senior Indebtedness;
               Preservation of Trustee's Rights.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article 11 with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall deprive
the Trustee of any of its rights as such holder. Nothing in this Article 11
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

Section 11.12. Article Applicable to Paying Agents.

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Issuers and be then acting hereunder, the term
"Trustee" as used in this Article 11 shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article 11 in addition to or in place of the Trustee.

Section 11.13. No Suspension of Remedies.

                  Nothing contained in this Article 11 shall limit the right of
the Trustee or the Holders to take any action to accelerate the maturity of the
Notes pursuant to Article 6 or to pursue any rights or remedies hereunder or
under applicable law, subject to the rights, if any, under this Article 11 of
the holders, from time to time, of Senior Indebtedness.

Section 11.14. Acceleration of Payment of Notes.

                  If payment of the Notes is accelerated because of an Event of
Default, the Company or the Trustee shall promptly notify the holders of Senior
Indebtedness of any Issuer or the Representative of such holders of the
acceleration (in the case

                                     -138-

of the Trustee, only to the extent of its actual knowledge of such holders or
the Representative of such holders). Such notice is in addition to, and not in
lieu of, any notice that may be required to be delivered under Section 6.02
prior to the effectiveness of any such acceleration.

Section 12.04. Certificate and Opinion as to Conditions Precedent.

                  Upon any request or application by the Issuers or any
Guarantor to the Trustee to take any action under this Indenture, the Issuers or
such Guarantor, as the case may be, shall furnish to the Trustee if and to the
extent reasonably requested by the Trustee:

                  (1) an Officers' Certificate (which shall include the
         statements set forth in Section 11.05 below) stating that, in the
         opinion of the signers, all conditions precedent, if any, provided for
         in this Indenture relating to the proposed action have been complied

                  (2) an Opinion of Counsel (which shall include the statements

         counsel, all such conditions precedent have been complied with.

         opinion has read such covenant or condition;

                  (2) a brief statement as to the nature and scope of the

         Person, such covenant or condition has been complied with.

Section 12.06. When Treasury Notes Disregarded.

                  In determining whether the Holders of the required aggregate
principal amount of Notes have concurred in any direction, waiver or consent,
Notes owned by the Issuers, any Guarantor or any other obligor on the Notes or
by any Affiliate of any of them shall be disregarded, except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes which the Trustee actually knows
are so owned shall be so disregarded. Notes so owned which have been pledged in
good faith shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to the
Notes and that the pledgee is not an Issuer, any Guarantor or any other obligor
upon the Notes or any Affiliate of any of them.

Section 12.07. Rules by Trustee and Agents.

                  The Trustee may make reasonable rules for action by or at

rules for their functions.

Section 12.08. Business Days; Legal Holidays.

                  A "Business Day" is a day that is not a Legal Holiday. A
"Legal Holiday" is a Saturday, a Sunday, a federally-recognized holiday or a day
on which banking institutions are not required to be open in the State of New
York. If a payment date is a Legal Holiday at a place of payment, payment may be
made at that place on the next succeeding day that is not a Legal Holiday, and
no interest shall accrue for the intervening period.

Section 12.09. Governing Law.

                  THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO
THE

ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE NOTES.

Section 12.10. No Adverse Interpretation of Other Agreements.

                  This Indenture may not be used to interpret another indenture,
loan, security or debt agreement of any Issuer or any Subsidiary thereof. No
such indenture, loan, security or debt agreement may be used to interpret this
Indenture.

Section 12.11. No Recourse Against Others.

                  A director, officer, employee, stockholder or incorporator, as
such, of any Issuer or any Guarantor shall not have any liability for any
obligations of any Issuer or any Guarantor under the Notes, the Guarantees or
this Indenture or for any claim based on, in respect of or by reason of such
obligations or their creations. Each Noteholder by accepting a Note waives and
releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Notes.

Section 12.12. Successors.

                  All agreements of each of the Issuers and each Guarantor in

                  The table of contents, cross-reference sheet and headings of
the Articles and Sections of this Indenture have been inserted for convenience

Section 12.15. Separability.

                  Each provision of this Indenture shall be considered separable
and if for any reason any provision which is not essential to the effectuation
of the basic purpose of this Indenture or the Notes shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                  IN WITNESS WHEREOF, the parties have caused this Indenture to
be duly executed all as of the date and year first written above.

1. INTEREST.

                  Muzak, LLC, a Delaware limited liability company (the
"Company"), and Muzak Finance Corp., a Delaware corporation ("Finance Corp." and
together with the Company, the "Issuers"), promise to pay interest on the
principal amount of this Note from the date of original issuance hereof at the
rate per annum, determined as of each Interest Rate Determination Date (as
defined below), equal to (i) from the period commencing on the Issue Date and
through and including July 31, 2000, LIBOR (as defined below) plus 5.00%; (ii)
from the period commencing on August 1, 2000 through and including October 31,
2000, LIBOR (as defined below) plus 7.50%; and (iii) from the period commencing
on November 1, 2000 and through and including the Maturity Date, a fixed rate of
interest equal to the greater of (x) LIBOR (as defined below) plus 7.50% and (y)
the Yield to Worst on the Existing Notes (as determined as of November 1, 2000,
or if such date is not a Business Day the next preceding Business Day) plus
2.50%, in each case as determined by the Calculation Agent. If this Note is
issued on any date other than an Interest Rate Determination Date, this Note
shall, until the immediately succeeding Interest Rate Determination Date, bear
interest at a rate per annum calculated as of the Interest Rate Determination
Date immediately preceding the date of original issuance of this Note. Interest
on this Note will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from the date of original issuance of
this Note. The Issuers will pay interest quarterly in arrears on each March 15,
June 15, September 15 and December 15 and at stated maturity (each, an "Interest
Payment Date"), commencing March 15, 2000, for the period commencing on and
including the immediately preceding Interest Payment Date and ending on and
including the day next preceding the Interest Payment Date (an "Interest
Period"), with the exception that the first Interest Period shall commence on
and include the date of the original issuance of this Note and end on and
include March 14, 2000.

                  The Issuers shall pay interest on overdue principal and on
overdue installments of interest from time to time on demand at the rate borne
by this Note (without regard to any applicable grace periods) to the extent
lawful.

                  "Determination Date," with respect to an Interest Rate
Determination Date, will be the second London Banking Day preceding the Interest
Rate Determination Date.

                  "Interest Rate Determination Date" means the first day of each
calendar month in each period described in clauses (i), (ii) and (iii) of the
first sentence of this Paragraph 1; provided that the first Interest Rate
Determination Date shall be the Issue Date; and provided, further, that, with
respect to the period described in clause (iii) of the first sentence of this
Paragraph 1, the "Interest Rate Determination Date" shall be November 1, 2000.

                  "LIBOR", with respect to any Interest Rate Determination Date,
shall be the rate (expressed as a percentage per annum) for deposits in United
States dollars for a three-month period beginning on the second London Banking
Day (as defined) after the Determination Date (as defined) that appears on
Telerate Page 3750 (as defined) as of 11:00 a.m., London time, on the
Determination Date. If Telerate Page 3750 does not include such a rate or is
unavailable on a Determination Date, LIBOR as of the Interest Rate Determination
Date shall be the arithmetic mean of the rates (expressed as a percentage per
annum) for deposits in a Representative Amount (as defined) in United States
dollars for a three-month period beginning on the second London Banking Day
after the Determination Date that appear on Reuters Screen LIBO Page (as
defined) as of 11:00 a.m., London time, on the Determination Date. If Reuters
Screen LIBO Page does not include two or more rates or is unavailable on a
Determination Date, the Calculation Agent will request the principal London
office of each of four major banks in the London interbank market, as selected
by the Calculation Agent, to provide such bank's offered quotation (expressed as
a percentage per annum), as of approximately 11:00 a.m., London time, on such
Determination Date, to prime banks in the London interbank market for deposits
in a Representative Amount in United States dollars for a three-month period
beginning on the second London Banking Day after the Determination Date. If at
least two such offered quotations are so provided, LIBOR as of the Interest Rate
Determination Date will be the arithmetic mean of such quotations. If fewer than
two such quotations are so provided, the Calculation Agent will request each of
three major banks in New York City, as selected by the Calculation Agent, to
provide such bank's rate (expressed as a percentage per annum), as of
approximately 11:00 a.m., New York City time, on such Determination Date, for
loans in a Representative Amount in United States dollars to leading European
banks for a three-month period beginning on the second London Banking Day after
the Determination Date. If at least two such rates are so provided, LIBOR as of
the Interest Rate Determination Date will be the

                                      A-6
<PAGE>
arithmetic mean of such rates. If fewer than two such rates are so provided,
then LIBOR as of the Interest Rate Determination Date will be LIBOR in effect
with respect to the immediately preceding Interest Rate Determination Date.

                  "London Banking Day" is any day in which dealings in United
States dollars are transacted or, with respect to any future date, are expected
to be transacted in the London interbank market.

                  "Representative Amount" means a principal amount of not less
than U.S. $1,000,000 for a single transaction in the relevant market at the
relevant time.

                  "Reuters Screen LIBO Page" means the display designated as
page "LIBO" on The Reuters Monitor Money Rates Service (or such other page as
may replace the LIBO page on that service).

                  "Telerate Page 3750" means the display designated as "Page
3750" on the Dow Jones Telerate Service (or such other page as may replace Page
3750 on that service).

                  "Yield to Worst" means, as of the date of determination, (i)
if the trading price of the Existing Notes exceeds 100% of the principal amount
thereof, the yield to March 15, 2004, and (ii) if the trading price of the
Existing Notes equals or is less than 100% of the principal amount thereof, the
yield to the stated maturity date of the Existing Notes.

                  The amount of interest for each day that this Note is
outstanding (the "Daily Interest Amount") will be calculated by dividing the
interest rate in effect for such day by 360 and multiplying the result by the
principal amount of this Note. The amount of interest to be paid on this Note
for each Interest Period will be calculated by adding the Daily Interest Amounts
for each day in the Interest Period.

                  All percentages resulting from any of the above calculations
will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, with five one-millionths of a percentage point rounded upwards
(e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all
dollar amounts used in or resulting from such calculations will be rounded to
the nearest cent (with one-half cent being rounded upwards).

                  The interest rate on this Note will in no event be higher than
16.00% per annum (before giving effect to any obligation to pay Additional
Interest (as defined in the Registra-

                                      A-7
<PAGE>
tion Rights Agreement), if any) with a maximum cash interest rate of 14.00% per
annum. Any interest in excess of 14.00% (and only such interest in excess of
14.00% per annum) shall be payable by the Issuers through the issuance of
Additional Notes in a principal amount equal to the amount of such interest in
excess of 14.00%; provided that Additional Interest (as defined in the
Registration Rights Agreement) may only be paid in cash and not through the
issuance of Additional Notes.

                  The Calculation Agent will, upon the request of the holder of
any Note, provide the interest rate then in effect with respect to this Note.
All calculations made by the Calculation Agent in the absence of manifest error
shall be conclusive for all purposes and binding on the Company and the Holders
of this Note.

2. METHOD OF PAYMENT.

                  The Issuers will pay interest on this Note provided for in
Paragraph 1 above (except defaulted interest) to the person who is the
registered Holder of this Note at the close of business on the March 1, June 1,
September 1 and December 1 preceding the Interest Payment Date (whether or not
such day is a Business Day). The Holder must surrender this Note to a Paying
Agent to collect principal payments. The Issuers will pay principal, premium, if
any, and interest in money of the United States that at the time of payment is
legal tender for payment of public and private debts; provided, however, that
the Issuers may pay principal, premium, if any, and interest by check payable in
such money or in Additional Notes pursuant to Paragraph 1 hereof. The Issuers
may mail an interest check to the Holder's registered address.

3. PAYING AGENT, REGISTRAR AND CALCULATION AGENT.

                  Initially, State Street Bank and Trust Company, a
Massachusetts banking corporation (the "Trustee"), will act as Paying Agent,
Registrar and Calculation Agent. The Issuers may change any Paying Agent,
Registrar or Calculation Agent without notice to the Holders. Neither the
Issuers nor any of its Subsidiaries or Affiliates may act as Paying Agent or
Calculation Agent but may act as Registrar or co-Registrar.

4. INDENTURE; RESTRICTIVE COVENANTS.

                  The Issuers issued this Note under an Indenture dated as of
February 2, 2000 (the "Indenture") among the Issuers, the Guarantors and the
Trustee. The terms of this Note include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939 (15

Code Sections 77aaa-77bbbb) as in effect on the date of the Indenture. This Note
is subject to all such terms, and the Holder of this Note is referred to the
Indenture and said Trust Indenture Act for a statement of them. All capitalized
terms in this Note, unless otherwise defined, have the meanings assigned to them
by the Indenture.

                  The Notes are general unsecured obligations of the Issuers
limited to $50,000,000 aggregate principal amount (excluding any Additional
Notes), $12,000,000 of which were issued on the Issue Date. The Indenture
imposes certain restrictions on, among other things, the incurrence of
indebtedness, the incurrence of liens, the making of certain investments,
mergers and sale of assets, the payments of dividends on or the repurchase of,
capital stock of the Issuers, certain other restricted payments by the Issuers
and their Subsidiaries, certain transactions with, and investments in, their
Affiliates, the creation of Subsidiaries, the issuance of capital stock by
Subsidiaries, the types of businesses which the Issuers and their Subsidiaries
may engage in, the creation of dividend and other payment restrictions affecting

change-of-control transactions.

denominations of $1,000 and integral multiples thereof. A Holder may register
the transfer or exchange of Notes in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Note selected for redemption or register the transfer of or
exchange any Note for a period of 15 days before a selection of Notes to be
redeemed or any Note after it is called for redemption in whole or in part,
except the unredeemed portion of any Note being redeemed in part.

11. PERSONS DEEMED OWNERS.

                  The registered Holder of this Note may be treated as the owner
of it for all purposes.

                                      A-12
<PAGE>
12. UNCLAIMED MONEY.

                  If money for the payment of principal, premium or interest on
any Note remains unclaimed for two years, the Trustee or Paying Agent will pay
the money back to the Issuers at its request. After that, Holders entitled to
money must look to the Issuers for payment as general creditors unless an
"abandoned property" law designates another person.

13. AMENDMENT, SUPPLEMENT AND WAIVER.

                  Subject to certain exceptions, the Indenture or the Notes may
be modified, amended or supplemented by the Issuers, the Guarantors and the
Trustee 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 may be waived in a particular instance with the consent of the
Holders of a majority in principal amount of the Notes then outstanding. Without
the consent of Holders, the Issuers, and the Trustee may amend the Indenture or
the Notes or supplement the Indenture for certain specified purposes including
providing for uncertificated Notes in addition to certificated Notes, and curing
any ambiguity, defect or inconsistency, or making any other change that does not
materially and adversely affect the rights of any Holder.

14. SUCCESSOR ENTITY.

                  When a successor entity assumes all the obligations of its
predecessor under the Notes and the Indenture and immediately before and
thereafter no Default exists and certain other conditions are satisfied, the
predecessor entity will be released from those obligations.

15. DEFAULTS AND REMEDIES.

                  Events of Default are set forth in the Indenture. If an Event
of Default (other than an Event of Default pursuant to Section 6.01(g) or (h) of
the Indenture with respect to the Company) occurs and is continuing, the Trustee
by notice to the Company, or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, may declare to be immediately
due and payable the entire principal amount of all the Notes then outstanding
plus accrued but unpaid interest to the date of acceleration; provided, however,
that after such acceleration but before judgment or decree based on such
acceleration is obtained by the Trustee, the Holders of a majority in aggregate
principal amount of the outstanding Notes may, under certain circumstances,
rescind and annul such acceleration and its consequences if all existing Events
of Default, other

                                      A-13
<PAGE>
than the nonpayment of principal, premium or interest that has become due solely
because of the acceleration, have been cured or waived and if the rescission
would not conflict with any judgment or decree. No such rescission shall affect
any subsequent Default or impair any right consequent thereto. In case an Event
of Default specified in Section 6.01(g) or (h) of the Indenture occurs, such
principal amount, together with premium, if any, and interest with respect to
all of the Notes, shall be due and payable immediately without any declaration
or other act on the part of the Trustee or the Holders of the Notes.

16. TRUSTEE DEALINGS WITH THE ISSUERS.

                  The Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Issuers, and may otherwise deal with the Issuers, as if it were not
Trustee.

17. NO RECOURSE AGAINST OTHERS.

                  As more fully described in the Indenture, a director, officer,
employee or stockholder, as such, of the Issuers or any Guarantor shall not have
any liability for any obligations of the Issuers or the Guarantors under the
Notes, the Guarantees or the Indenture or for any claim based on, in respect or
by reason of, such obligations or their creation. The Holder of this Note by
accepting this Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of this Note.

18. DEFEASANCE AND COVENANT DEFEASANCE.

                  The Indenture contains provisions for defeasance of the entire
indebtedness on this Note and for defeasance of certain covenants in the
Indenture upon compliance by the Issuers with certain conditions set forth in
the Indenture.

19. 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).

20. CUSIP NUMBERS.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Securities Identification Procedures, the Issuers have caused CUSIP
Numbers to be printed on the Notes and

                                      A-14
<PAGE>
have directed the Trustee to use CUSIP numbers in notices of redemption as
convenience to Holders of the Notes. 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.

MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW. EACH OF THE PARTIES TO THE INDENTURE HAS AGREED TO SUBMIT TO

Muzak Finance Corp.


State Street Bank and Trust Company
c/o  State Street Bank and Trust Company
     225 Franklin Street
     Boston, Massachusetts  02110
     Attention:  Corporate Trust Department

Ladies and Gentlemen:

                  In connection with our proposed purchase of $        aggregate
principal amount of the Senior Subordinated Floating Rate Notes due 2009 (the
"Notes") of Muzak LLC (the "Company") and Muzak Finance Corp. (together with the
Company, the "Issuers"), we confirm that:

                  1. We understand that none of the Notes has been registered
         under the Securities Act of 1933, as amended (the "Securities Act"),
         and, unless so registered, may not be sold except as permitted in the
         following sentence. We agree on our own behalf and on behalf of any
         investor account for which we are purchasing any Notes to offer, sell
         or otherwise transfer any such Notes prior to the date the "Resale
         Restriction Termination Date") that is two years after the later of the
         original issuance of this Note and the last date on which any Issuer,
         or any Affiliate of any Issuer, was the owner of this Note (or any
         predecessor of this Note) except (A) to any Issuer or any subsidiary
         thereof, (B) inside the United States to a Qualified Institutional
         Buyer in compliance with Rule 144A under the Securities Act, (C) inside
         the United States to an Institutional Accredited Investor within the
         meaning of subparagraph (a)(1),(2),(3) or (7) of Rule 501 under the
         Securities Act that, prior to such transfer, furnishes (or has
         furnished on its behalf by a U.S. broker-dealer) to the Trustee a
         signed letter substantially in the form of this letter, (D) outside the
         United States in an offshore transaction in compliance with Rule 904
         under the Securities Act, (E) pursuant to any other available exemption
         from the registration requirements of the Securities Act or (F)
         pursuant to an effective Registration Statement under the Securities
         Act. Each purchaser acknowledges that the Issuers and the Trustee
         reserve the right prior to any

                                     D-2-1
<PAGE>
         offer, sale or other transfer prior to the Resale Restriction
         Termination Date of the applicable Notes pursuant to clause (c) or (e)
         above to require the delivery of an opinion of counsel, certification
         and/or other information satisfactory to the Issuers and the Trustee.

                  2. We are an Institutional Accredited Investor purchasing such
         Notes for our own account or for the account of one or more
         Institutional Accredited Investors, and we are acquiring such Notes for
         investment purposes and not with a view to, or for offer or sale in
         connection with, any distribution in violation of the Securities Act or
         the securities laws of any state of the United States and we have such
         knowledge and experience in financial and business matters as to be
         capable of evaluating the merits and risks of our investment in such
         Notes, and we and any accounts for which we are acting are each able to
         bear the economic risk of our or its investment in such Notes for an
         indefinite period.

                  3. We acknowledge that we have had access to such financial
         and other information, and have been afforded the opportunity to ask
         such questions of representatives of the Issuers and receive answers
         thereto, as we deem necessary.

         properties, prospects or results of operations of the Issuers, taken as
         a whole (any such event, a "Material Adverse Effect").

         non-assessable and none of them have been issued in violation of any
         preemptive or other right; and (ii) no holder of securities of any
         Issuer is entitled to have such securities registered under the
         Registration Statement.

         Private Exchange Notes. The Notes, the Exchange Notes and the Private
         Exchange Notes have each been duly and validly authorized by each of
         the Notes Issuers for issuance and, when executed by the Notes Issuers
         and authenticated by the Trustee in accordance with the provisions of
         the Indenture and, in the case of the Notes, when delivered to and paid
         for by the Purchaser in accordance with the terms hereof, will have

                                      -4-

         been duly executed, issued and delivered and will constitute valid and
         legally binding obligations of the Notes Issuers, entitled to the
         benefits of the Indenture and enforceable against the Notes Issuers in
         accordance with their terms except that the enforcement thereof may be
         limited by (i) bankruptcy, insolvency, reorganization, moratorium or
         other similar laws now or hereafter in effect relating to or affecting
         creditors' rights generally and (ii) general principles of equity
         (regardless of whether such enforcement is considered in a proceeding
         at law or in equity) and the discretion of the court before which any
         proceeding with respect thereto may be brought (the "Enforceability
         Exceptions"); the Guarantees to be endorsed on the Notes and the
         guarantees to be endorsed on the Exchange Notes and the Private
         Exchange Notes have each been duly and validly authorized by the
         Guarantors and, when the Notes are executed by the Notes Issuers and
         authenticated by the Trustee in accordance with the provisions of the
         Indenture, and delivered to and paid for by the Purchaser in accordance
         with the terms hereof, and when the Guarantees have been endorsed on
         the Notes in accordance with the terms of the Indenture, such
         Guarantees will have been duly executed, issued and delivered and will
         constitute valid and legally binding obligations of the Guarantors,
         entitled to the benefits of the Indenture and enforceable against the
         Guarantors in accordance with their terms except that the enforcement
         thereof may be limited by the Enforceability Exceptions. The Securities
         to be issued on such Closing Date are in the form contemplated by the
         Indenture.

                  (e) Each of the Issuers has the requisite corporate or limited
         liability company power and authority to execute, deliver and perform
         its obligations under the Indenture. The Indenture has been duly and
         validly authorized by the Issuers and meets the requirements for
         qualification under the Trust Indenture Act of 1939, as amended (the
         "TIA"), and, when executed and delivered by the Issuers (assuming the
         due authorization, execution and delivery by the Trustee), will
         constitute a valid and legally binding agreement of the Issuers,
         enforceable against the Issuers in accordance with its terms except
         that the enforcement thereof may be limited by the Enforceability
         Exceptions.

                  (f) Each of the Issuers has the requisite corporate or limited
         liability company power and authority to execute, deliver and perform
         its obligations under the Regis-

                                      -5-

         tration Rights Agreement. The Registration Rights Agreement has been
         duly and validly authorized by the Issuers and, when executed and
         delivered by the Issuers (assuming the due authorization, execution and
         delivery by the Purchaser), will constitute a valid and legally binding
         agreement of the Issuers, enforceable against the Issuers in accordance
         with its terms except (i) that the enforcement thereof may be limited
         by the Enforceability Exceptions and (ii) as any rights to indemnity or
         contribution thereunder may be limited by federal and state securities
         laws and public policy considerations.

                  (g) Each of the Issuers has the requisite corporate or limited
         liability power and authority to execute, deliver and perform its
         obligations under this Agreement. This Agreement has been duly and
         validly authorized by the Issuers and, when executed and delivered by
         each Issuer (assuming due authorization, execution and delivery by the
         Purchaser), will constitute a valid and legally binding agreement of
         such Issuer, enforceable against such Issuer in accordance with its
         terms except (i) that the enforcement thereof may be limited by the
         Enforceability Exceptions and (ii) as any rights to indemnity or
         contribution hereunder may be limited by federal and state securities
         laws and public policy considerations.

                  (h) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the performance of any
         of the Transaction Documents by the Issuers, to the extent each is or
         will be a party thereto, or for the consummation by the Issuers of any
         of the transactions contemplated thereby or in connection with any
         Acquisition to be completed on such Closing Date, except for such
         consents, approvals, authorizations or orders as have been obtained or
         made or as may be required under the Securities Act and the TIA (with
         respect to the transactions contemplated by the Registration Rights
         Agreement) or as may be required under state securities or "Blue Sky"
         laws in connection with the purchase of the Securities by the Purchaser
         or such that the failure to obtain would not reasonably be expected to
         have a Material Adverse Effect; and none of the Issuers or the
         Subsidiaries is (i) in violation of its respective certificate of
         incorporation, organizational documents, limited liability company
         agreement, partnership agreement or bylaws, (ii) in violation of any
         statute, judgment, decree, order, rule or regulation applicable to it
         or any of its properties or assets, which violation would, individually
         or in
<PAGE>
                                      -6-

         the aggregate, have a Material Adverse Effect, or (iii) in default in
         the performance or observance of any obligation, agreement, covenant or
         condition contained in any of the Transaction Documents or any other
         contract, indenture, mortgage, deed of trust, loan agreement, note,
         lease, license, franchise agreement, permit, certificate or agreement
         or instrument to which it is a party or to which it is subject, which
         default would, individually or in the aggregate, have a Material
         Adverse Effect.

                  (i) The execution, delivery and performance by the Issuers of
         each of the Transaction Documents to which any of them is a party, and
         the consummation of the transactions contemplated hereby and thereby
         and by the Acquisitions to be completed on such Closing Date and the
         fulfillment of the terms hereof and thereof, will not violate, conflict
         with or constitute or result in a breach of or a default under (or an
         event that, with notice or lapse of time, or both, would constitute a
         breach of or a default under) any of (a) the terms or provisions of any
         indenture, mortgage, deed of trust, loan agreement, note, lease,
         license, franchise agreement, or agreement or instrument to which any
         of them is a party or to which any of their respective properties or
         assets are subject (each as in effect on such Closing Date), which
         violation, conflict, breach or default would, individually or in the
         aggregate, have a Material Adverse Effect, (b) the certificate of
         incorporation, organizational documents, limited liability company
         agreement, partnership agreement or by-laws of any of them or (c)
         (assuming compliance with all applicable Federal and state securities
         and "Blue Sky" laws and the accuracy of the representations and
         warranties of the Purchaser in Section 8 hereof) any statute, judgment,
         decree, order, rule or regulation of any court or governmental agency
         or other body applicable to any of them or any of their respective
         properties or assets, which violation, conflict, breach or default
         would, individually or in the aggregate, have a Material Adverse
         Effect.

                  (j) The audited historical financial statements of the Company
         as of December 31, 1998 and for the year ended December 31, 1998
         present fairly in all material respects the financial position, results
         of operations and cash flows of the Company at the dates and for the
         periods to which they relate and have been prepared in accordance with
         generally accepted accounting principles applied on a consistent basis,
         except as otherwise stated therein; the
<PAGE>
                                      -7-

         unaudited historical financial statements of the Company as of
         September 30, 1999 and for the nine-month period ended September 30,
         1999 included in the Company's quarterly report on Form 10-Q filed with
         the Commission present fairly in all material respects the financial
         position and results of operations of the Company at the dates and for
         the periods to which they relate and have been prepared in accordance
         with generally accounting principles applied on a consistent basis
         except as otherwise stated therein, subject to normal and customary
         year-end adjustments which would not, individually or in the aggregate,
         have a Material Adverse Effect; and PricewaterhouseCoopers LLP, which
         has examined such audited financial statements and reviewed such
         unaudited financial statements, is an independent public accounting
         firm within the meaning of Rule 101 of the Code of Professional Conduct
         of the American Institute of Certified Public Accountants and its
         interpretations and rulings.

                  (k) The pro forma financial statements and other pro forma
         financial information (including the notes thereto) provided to the
         Purchasers by the Issuers have been properly computed on the bases
         described therein; and the assumptions used in the preparation of the
         pro forma financial statements and other pro forma financial
         information provided to the Purchaser by the Issuers are reasonable and
         the adjustments used therein are appropriate to give effect to the
         transactions or circumstances referred to therein.

                  (l) The financial projections entitled "Muzak Quarterly 1.6
         Model" furnished to the Purchaser by the Issuers, were prepared by or
         under the direction of an officer of the Issuers and were prepared in
         good faith on the basis of information and assumptions that the Issuers
         believe to be fair and reasonable as of the date of such projections;
         provided that such projections are not to be viewed as facts and that
         actual results during the period or periods covered by such projections
         may differ from such projections and that the differences may be
         material. All other factual information heretofore or contemporaneously
         furnished in writing by or on behalf of any Issuer to the Purchaser for
         purposes of or in connection with the Transaction Documents is complete
         and accurate in all material respects. No fact is known, no condition
         exists nor has any event occurred which has not been disclosed herein
         or in any other document, certificate or statement furnished to the
         Purchaser for use in the transactions

                                      -8-

         contemplated hereby which, individually or in the aggregate, would have
         a Material Adverse Effect.

                  (m) The Issuers have filed with the Commission certain
         registration statements and reports, including the Company's Quarterly
         Report on Form 10-Q for the nine month period ended September 30, 1999
         (including exhibits, annexes and any amendments thereto) (collectively,
         including any such reports filed subsequent to the date hereof and as
         amended, the "Company Reports"). As of their respective dates (or, if
         amended, as of the date of such amendment) the Company Reports did not
         contain any untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements made therein, in light of the circumstances in which they
         were made, not misleading.

                  (n) Except as disclosed in the Company's Registration
         Statement on Form S-4 (Registration No. 333-78571) (as amended to the
         Initial Closing Date) under the heading "Business-Legal Proceedings,"
         there is not pending or, to the best knowledge of the Notes Issuers,
         threatened any action, suit, proceeding, inquiry or investigation,
         governmental or otherwise, to which any of the Issuers is a party, or
         to which their respective properties or assets are subject, before or
         brought by any court, arbitrator or governmental agency or body, that,
         if determined adversely to the Issuers would, individually or in the
         aggregate, have a Material Adverse Effect, or that seeks to restrain,
         enjoin, prevent the consummation of or otherwise challenge the issuance
         or sale of the Securities to be sold hereunder or any Acquisition.

                  (o) None of the Issuers has, and, after giving effect to the
         issuance and sale of the Securities or any Acquisition to be completed
         on such Closing Date, none of the Issuers will have, any liability for
         any prohibited transaction or funding deficiency or any complete or
         partial withdrawal liability with respect to any pension, profit
         sharing or other plan which is subject to the Employee Retirement
         Income Security Act of 1974, as amended ("ERISA"), to which any of them
         makes or ever has made a contribution and in which any employee of any
         of them is or has ever been a participant. With respect to such plans,
         the Issuers are, and, to the best knowledge of the Issuers, after
         giving effect to the issuance and sale of the Securities and each
         Acquisition to be completed on
<PAGE>
                                      -9-

         such Closing Date, the Issuers will be, in compliance in all material
         respects with all provisions of ERISA.

                  (p) The Issuers own or possess adequate licenses or other
         rights to use all patents, trademarks, service marks, trade names,
         copyrights and know-how that are necessary to conduct their business,
         except where the failure to own or possess would not individually or in
         the aggregate have a Material Adverse Effect. None of the Issuers has
         received any notice of infringement of or conflict with (or knows of
         any such infringement of or conflict with) asserted rights of others
         with respect to any patents, trademarks, service marks, trade names,
         copyrights or know-how that, if such assertion of infringement or
         conflict were sustained, would, individually or in the aggregate, have
         a Material Adverse Effect.

                  (q) Each of the Issuers possesses all licenses, permits,
         certificates, consents, orders, approvals and other authorizations
         from, and has made all declarations and filings with, all federal,
         state, local and other governmental authorities, all self-regulatory
         organizations and all courts and other tribunals presently required or
         necessary to own or lease, as the case may be, and to operate its
         respective properties and to carry on its respective businesses as
         conducted or proposed to be conducted on such Closing Date ("Permits"),
         except where the failure to obtain such Permits would not, individually
         or in the aggregate, have a Material Adverse Effect; each of the
         Issuers 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, except for nonperformance or events or revocations or
         terminations that would not, individually or in the aggregate, have a
         Material Adverse Effect; and none of the Issuers has received any
         notice of any proceeding relating to revocation or modification of any
         such Permit, except where such revocation or modification would not,
         individually or in the aggregate, have a Material Adverse Effect.

                  (r) Subsequent to the date of the most recent unaudited
         consolidated balance sheet of the Company provided to the Purchaser as
         described in the first sentence of Section 2(j), none of the Issuers
         has sustained any material loss or interference with its business from
         fire, ex-
<PAGE>
                                      -10-

         plosion, flood, earthquake or other calamity, whether or not covered by
         insurance, except in each case as would not have a Material Adverse
         Effect.

                  (s) None of the Issuers has taken or will take any action that
         would cause this Agreement or the issuance or sale of the Securities to
         violate Regulation T, U or X of the Board of Governors of the Federal
         Reserve System, in each case as in effect or as the same may hereafter
         be in effect, on such Closing Date.

                  (t) Each of the Issuers has good and marketable title to all
         real property owned by it and good and marketable title to the
         leasehold estate in the real property leased by it, free and clear of
         all liens, charges, encumbrances or restrictions, except as would not,
         individually or in the aggregate, have a Material Adverse Effect.

                  (u) Each of the Issuers has filed all necessary federal, state
         and foreign income and franchise tax returns, except where the failure
         to so file such returns would not, individually or in the aggregate,
         have a Material Adverse Effect, and, other than taxes due thereon or
         tax deficiencies which any Issuer reasonably believes that it has
         provided adequate reserves, has paid all taxes due thereon and there is
         no tax deficiency that has been asserted against any Issuer or that
         would, individually or in the aggregate, have a Material Adverse
         Effect.

                  (v) (i) Immediately after the consummation of the transactions
         contemplated by the Transaction Documents and each Acquisition to be
         completed on such Closing Date, the fair value and present fair
         saleable value of the assets of the Issuers will exceed the sum of
         their stated liabilities and identified contingent liabilities; and
         (ii) the Issuers are not, nor will they be, after giving effect to the
         execution, delivery and performance of the Transaction Documents and
         the consummation of the transactions contemplated thereby, (a) left
         with unreasonably small capital with which to carry on their businesses
         as is proposed to be conducted, (b) unable to pay their debts
         (contingent or otherwise) as they mature or (c) insolvent.

                  (w) Except as would not individually or in the aggregate have
         a Material Adverse Effect, (A) each of the Issuers is in compliance
         with all applicable Environmental Laws, (B) each of the Issuers has
         made all filings and provided all notices required under any applicable
         Envi-
<PAGE>
                                      -11-

         ronmental Law, and has all permits, authorizations and approvals
         required under any applicable Environmental Laws and is in compliance
         with their requirements, (C) there are no pending or, to the best
         knowledge of the Issuers, after due inquiry, threatened Environmental
         Claims against any of the Issuers and (D) none of the Issuers has
         knowledge of any circumstances with respect to any of their respective
         properties or operations that could reasonably be anticipated to form
         the basis of an Environmental Claim against any of them or any of their
         subsidiaries or any of their respective properties or operations and
         the business operations relating thereto.

                  For purposes of this Agreement, the following terms shall have
         the following meanings: "Environmental Law" means any federal, state,
         local or municipal statute, law, rule, regulation, ordinance, code or
         rule and any judicial or administrative interpretation thereof,
         including any judicial or administrative order, consent decree or
         judgment binding on any of the Issuers relating to pollution or
         protection of the environment or health or safety or any chemical,
         material or substance that is subject to regulation thereunder.
         "Environmental Claims" means any and all administrative, regulatory or
         judicial actions, suits, demands, demand letters, claims, written
         notices of responsibility, information requests, liens, written notices
         of noncompliance or violation, investigations or proceedings relating
         in any way to any Environmental Law.

                  (x) None of the Issuers or any of their respective Affiliates
         (as defined in Rule 501(b) of Regulation D under the Securities Act)
         directly, or through any agent, (i) sold, offered for sale, solicited
         offers to buy or otherwise negotiated in respect of any "security" (as
         defined in the Securities Act) which is or could be integrated with the
         sale of the Securities in a manner that would require the registration
         under the Securities Act of the Securities or (ii) engaged in any form
         of general solicitation or general advertising (as those terms are used
         in Regulation D under the Securities Act) in connection with the
         offering of the Securities or in any manner involving a public offering
         within the meaning of Section 4(2) of the Securities Act. Assuming the
         accuracy of the Purchaser's representations and warranties set forth in
         Section 8 hereof, the offer and sale of the Securities to the Purchaser
         in the manner contemplated by this Agreement does not require
         registration under the Securities

                                      -12-

         Act and the Indenture does not require qualification under the TIA.

                  (y) No securities of any Issuer are (i) of the same class
         (within the meaning of Rule 144A under the Securities Act) as the
         Securities and (ii) listed on a national securities exchange registered
         under Section 6 of the Securities Exchange Act of 1934, as amended (the
         "Exchange Act") or quoted in a U.S. automated interdealer quotation
         system.

                  (z) None of the Issuers or, any of their respective Affiliates
         or any person acting on their behalf, has engaged in any directed
         selling efforts (as that term is defined in Regulation S under the
         Securities Act ("Regulation S")) with respect to the Securities; and
         the Issuers, their respective Affiliates and any person acting on their
         behalf have acted in accordance with the offering restrictions
         requirements of Regulation S.

                  (aa) None of the Issuers is required to register as an
         "investment company" within the meaning of the Investment Company Act
         of 1940, as amended.

         directors, officers or controlling persons, has taken, directly or
         indirectly, any action designed, or that might reasonably be expected,
         to cause or result, under the Act or otherwise, in, or that has
         constituted, stabilization or manipulation of the price of any security
         of any Issuer to facilitate the sale or resale of the Securities (it
         being understood that no representation or warranty is made as to any
         actions by the Purchaser).

                  (cc) There is no strike, labor dispute, slowdown or work
         stoppage with the employees of any of the Issuers which is pending or,
         to the best knowledge of the Issuers, threatened that would have a
         Material Adverse Effect.

                  (dd) Each of the Issuers carries insurance (including
         self-insurance) in such amounts and covering such risks as in its
         reasonable determination is adequate for the conduct of its business
         and the value of its properties.

                  (ee) Each of the Issuers (i) makes and keeps accurate books
         and records and (ii) maintains internal accounting controls which
         provide reasonable assurance that
<PAGE>
                                      -13-

         (A) transactions are executed in accordance with management's
         authorization, (B) transactions are recorded as necessary to permit
         preparation of its financial statements and to maintain accountability
         for its assets, (C) access to its assets is permitted only in
         accordance with management's authorization and (D) the reported
         accountability for its assets is compared with existing assets at
         reasonable intervals.

                  (ff) Since the date of the most recent balance sheet provided
         to the Purchaser prior to the Initial Closing Date, the Company has
         received a contribution to its common equity capital from its existing
         stockholders of at least $4.336 million (the "New ABRY Equity
         Contribution") and shall have requested that its existing stockholders
         contribute an additional $6.3 million to the Company's common equity
         capital.

                  Any certificate signed by any officer of any Issuer and
delivered to the Purchaser or to counsel for the Purchaser shall be deemed a
joint and several representation and warranty by the Issuers to the Purchaser as
to the matters covered thereby.

                  3. Purchase, Sale and Delivery of the Securities.

                  (a) The Note Issuers hereby agree to issue and sell to the
Purchaser, and the Purchaser agrees, subject to and upon the terms and
conditions set forth herein, to purchase from the Note Issuers, at a price equal
to 100% of the principal amount thereof, from time to time during the period
commencing on the Initial Closing Date (as defined herein) and ending at 5:00
p.m. New York time on July 31, 2000, Securities in an aggregate principal amount
not to exceed $50,000,000. On the Initial Closing Date the Purchaser agrees to

Securities. On each Subsequent Closing Date the Purchaser agrees to purchase
from the Notes Issuers the aggregate principal amount of Securities specified in
the Notice of Purchase (as defined herein) and otherwise subject to and upon the
terms and conditions set forth herein. Notwithstanding the foregoing (i) the
Purchaser shall not be obligated to purchase any Securities after 5:00 p.m. New
York time on July 31, 2000, (ii) the Purchaser shall not be required to purchase
any Securities if at the time of such purchase any Default (as defined in the
Indenture) or Event of Default (as defined in the Indenture) shall have occurred
and be continuing under the Indenture with respect to any outstanding
Securities, (iii) the aggregate prin-
<PAGE>
                                      -14-


cipal amount of Securities purchased on each Closing Date shall be at least
$2,500,000 or, if greater, an increment of $1,000,000 (i.e. $3,000,000,
$4,000,000, etc.) and (iv) the Purchaser shall not be required to purchase in
excess of $50,000,000 in aggregate principal amount of Securities pursuant to
this Agreement.

                  (b) The purchase by the Purchaser of Securities hereunder
shall occur substantially contemporaneously with the consummation of the
Acquisition which is to occur on such Closing Date and shall be made, subject to
the terms of this Agreement, in such principal amounts and at such times as the
Notes Issuers may designate in a written notice (the "Notice of Purchase")
(except for the purchase of Securities made pursuant to this Agreement on the
date hereof (the "Initial Closing Date") for which no such notice shall be
necessary) with respect thereto delivered to the Purchaser at least three
Business Days prior to the issue and sale thereof, provided that such notice
shall be deemed to have been given on a certain day only if given before 12:00
noon (New York time) on such day. For purposes of this Agreement, "Business Day"
means any day that is not a Legal Holiday and "Legal Holiday" means a Saturday,
a Sunday, a federally recognized holiday or a day on which banking institutions
are not required to be open in the State of New York.

                  Each Notice of Purchase shall be irrevocable and shall be
substantially in the form of Exhibit B hereto and shall be signed by the Chief
Executive Officer and the Chief Financial Officer of the Company, appropriately
completed to specify (i) the aggregate principal amount of the Securities to be
purchased pursuant to such Notice of Purchase (which shall be an amount not to
exceed the cash consideration to be paid to consummate the Acquisition to be
consummated on such Closing Date rounded upward to the nearest increment of
$1,000,000 (i.e. $3,000,000, $4,000,000, etc.)), (ii) the date and time of such
purchase (which shall occur during regular banking hours on a Business Day not
less than three nor greater than five Business Days from the date of delivery of
the Notice of Purchase) (each such date a "Subsequent Closing Date" and,
together with the Initial Closing Date, each a "Closing Date"), (iii) the
Acquisition which is to be consummated, (iv) the type(s) and amount(s) of
consideration to be delivered by the Company or its Subsidiaries to the
seller(s) of the business assets to be acquired in the applicable Acquisition
and (v) that the proceeds from the issuance and sale of the Securities will be
used solely as consideration for the Acquisitions contemplated by this Agreement
and to pay related costs actu-

                                      -15-

ally incurred by the Company (except to the extent of any proceeds from
Securities issued in order to round up as provided in clause (i) of this
paragraph).

                  One or more certificates in definitive form for the Securities
that the Purchaser has agreed to purchase hereunder, and in such denomination or
denominations and registered in such name or names as each Purchaser requests
upon notice to the Company at least 48 hours prior to a Closing Date, shall be
delivered by or on behalf of the Issuers, against payment by or on behalf of the
Purchaser of the purchase price therefor by wire transfer of immediately
available funds to the account of the Company previously designated by it in
writing. Such delivery of and payment for Securities issued on the Initial
Closing Date shall be made at the offices of Cahill Gordon & Reindel, 80 Pine
Street, New York, New York 10005, at 9:00 a.m., New York time, on February 2,
2000, or at such date as the Purchaser and the Company may agree upon. Such
delivery of and payment for Securities issued on a Subsequent Closing Date shall
be made at such date, place and time as the Purchaser and the Company may agree
upon. The Company will make such certificate or certificates for the Securities
to be purchased available for inspection by the Purchaser at the offices in New
York, New York of Cahill Gordon & Reindel at least 24 hours prior to each
Closing Date.

                  4. Certain Covenants. The Issuers, jointly and severally,
covenant and agree with the Purchaser that from and after the Initial Closing
Date and until the Securities and all obligations incurred hereunder and
thereunder are paid in full:

                  (a) The Issuers will cooperate with the Purchaser in arranging
         for the qualification of the Securities for offering and sale under the
         securities or "Blue Sky" laws of such jurisdictions as the Purchaser
         may designate and will continue such qualifications in effect for as
         long as may be necessary to complete the resale of the Securities by
         the Purchaser; provided, however, that in connection therewith none of
         the Issuers shall be required to qualify as a foreign corporation or to
         execute a general consent to service of process in any jurisdiction or
         to take any other action that would subject it to general service of
         process or to taxation in respect of doing business in any jurisdiction
         in which it is not otherwise subject.

                  (b) During the period of five years from the Closing Date, the
         Issuers will furnish to the Purchaser (a) as soon as available, a copy
         of each report and other commu-
<PAGE>
                                      -16-

         nication (financial or otherwise) of any Issuer mailed to the Trustee
         or the holders of the Securities, stockholders or any national
         securities exchange on which any class of securities of any Issuer may
         be listed other than materials filed with the Commission and (b) from
         time to time such other information concerning the Issuers as the
         Purchaser may reasonably request.

                  (c) If this Agreement shall terminate or shall be terminated
         after execution because of any failure or refusal on the part of the
         Issuers to comply with the terms or fulfill any of the conditions of
         this Agreement, the Issuers agree to reimburse the Purchaser for all
         reasonable out-of-pocket expenses (including fees and expenses of
         counsel for the Purchaser) incurred by you in connection herewith.

                  (d) The Issuers will apply the net proceeds from each sale of
         the Securities as set forth as provided herein or in the applicable
         Notice of Purchase, as the case may be.

                  (e) Prior to each Closing Date, the Company will furnish to
         the Purchaser, as soon as they have been prepared, a copy of any
         interim financial statements of the Company, if any, for any period
         subsequent to the period covered by the most recent financial
         statements previously delivered to the Purchaser.

                  (f) None of the Issuers or any of their respective Affiliates
         will sell, offer for sale or solicit offers to buy or otherwise
         negotiate in respect of any "security" (as defined in the Securities
         Act) which could be integrated with the sale of the Securities in a
         manner which would require the registration under the Securities Act of
         the Securities.

                  (g) For so long as the Securities constitute "restricted"
         securities within the meaning of Rule 144(a)(3) under the Securities
         Act, the Issuers will not, and will not permit any of the Subsidiaries
         to, solicit any offer to buy or offer to sell the Securities by means
         of any form of general solicitation or general advertising (as those
         terms are used in Regulation D under the Securities Act) or in any
         manner involving a public offering within the meaning of Section 4(2)
         of the Securities Act, except in connection with the exchange offer
         contemplated by the Registration Rights Agreement.
<PAGE>
                                      -17-

                  (h) For so long as any of the Securities remain outstanding
         and are "restricted securities" within the meaning of Rule 144(a)(3)
         under the Securities Act and not able to be sold in their entirety
         under Rule 144 under the Securities Act (or any successor provision),
         the Issuers will make available, upon request, to any seller of such
         Securities the information specified in Rule 144A(d)(4) under the
         Securities Act, unless the Issuers are then subject to Section 13 or
         15(d) of the Exchange Act.

                  (i) If requested by the Purchaser, the Issuers will use their
         best efforts to (i) permit the Securities to be included for quotation
         on the PORTAL Market and (ii) permit the Securities to be eligible for
         clearance and settlement through The Depository Trust Company ("DTC").

                  (j) The Issuers will use their best efforts to do and perform
         all things required to be done and performed by them under this
         Agreement and the other Transaction Documents prior to or after each
         Closing Date and to satisfy all conditions precedent on their part to
         the obligations of the Purchaser to purchase and accept delivery of the
         Securities.

                  (k) The Issuers who are a party to this Agreement as of the
         Initial Closing Date shall cause each Subsidiary of the Company formed
         or acquired after the Initial Closing Date which is required to
         Guarantee the Notes to become a party to this Agreement.

                  5. Expenses; Fees. (a) Notwithstanding any termination of this
Agreement (pursuant to Section 10 or otherwise), the Issuers jointly and
severally agree to pay the following costs and expenses and all other costs and
expenses incident to the performance by the Issuers of their obligations
hereunder: (i) the negotiation, preparation, printing, typing, reproduction,

the Securities for offer and sale under the securities or Blue Sky laws of the
several states (including filing fees and the reasonable fees, expenses and
disbursements of Cahill Gordon & Reindel, counsel to the Purchaser, relating to

expenses and disbursements of Cahill Gordon & Reindel, counsel to the Purchaser,
incurred in connection with the matters contemplated by the Transaction

(vii) fees and expenses of the Trustee including fees and expenses of its

                  (b) The Issuers hereby agree to pay to the Purchaser the
following fees: (i) a commitment fee equal to 0.75% of the maximum aggregate
principal amount of Securities which the Purchaser has agreed to purchase
pursuant to the terms and conditions of this Agreement which amount shall be
earned upon execution of this Agreement and which commitment fee shall be due

<PAGE>
                                      -19-

however, that in no event shall the amount of any Cancellation Fee credited
against any such fees, discounts and commissions exceed the amount of such fees,
discounts and commissions; provided, further, that no Cancellation Fee shall be
payable to the extent the Securities are redeemed or repurchased with the
proceeds of the issuance of preferred stock of the Company to ABRY Broadcast
Partners II, L.P., ABRY Broadcast Partners III, L.P. or any of their respective
affiliates (the "ABRY Preferred Stock"). The Issuers hereby authorize the
Purchaser to withhold from the consideration to be paid to the Notes Issuers on
each Closing Date an amount equal to the fees due and payable to the Purchaser
on such Closing Date and to withhold from any other amounts that may be due and
owing to any Note Issuer an amount equal to any other fees which may be due and
payable hereunder.

                  6. Conditions of the Purchaser's Obligations. The obligation
of the Purchaser to purchase and pay for the Securities on each Closing Date are

         (exclusive of any amendment or supplement thereto after the date
         hereof), there shall not have occurred any change, or any development
         involving a prospective change, in or affecting the general affairs,
         management, business, condition (financial or other), properties,

                                    b. At such Closing Date and after giving
                  effect to the consummation of the transactions contemplated by

                (viii) All proceedings taken in connection with the issuance of
         the Securities and the transactions contemplated by this Agreement and

                 (xii) The Issuers shall apply the proceeds from each issuance
         and sale of the Securities to consummate the Acquisitions to be
         consummated on such Closing Date as provided in this Agreement.

                (xiii) Since the date of this Agreement, there shall not have
         been any announcement by any "nationally recognized statistical rating
         organization," as defined for purposes of Rule 436(g) under the
         Securities Act, that (A) it is downgrading its rating assigned to any
         debt securities of any Issuer, or (B) it is reviewing its rating
         assigned to any debt securities of any Issuer with a view to possible
         downgrading, or with negative implications, or direction not
         determined.

                 (xiv) On or before the Initial Closing Date, the Purchaser
         shall have received the Engagement Letter dated as of the date hereof
         (the "Engagement Letter") by and among the Notes Issuers and the
         Purchaser and executed by the Notes Issuers and such agreement shall be
         in full force and effect at all times from and after the Initial
         Closing Date.

                  (xv) At such Closing Date and after giving effect to the
         consummation of the Acquisitions to be completed on such Closing Date
         and transactions contemplated by the Transaction Documents, there shall
         exist no Default or Event of Default (each as defined in the
         Indenture).

                 (xvi) The Purchaser shall have been furnished with evidence
         satisfactory to it that the New ABRY Equity Contribution shall have
         been consummated.

                (xvii) The Issuers shall have furnished or caused to be
         furnished to the Purchaser such further certificates and documents as
         the Purchaser shall have reasonably requested.
<PAGE>
                                      -23-

                  All such opinions, certificates, letters, schedules, documents
or instruments delivered pursuant to this Agreement will comply with the
provisions hereof only if they are reasonably satisfactory in all material
respects to the Purchaser and counsel to the Purchaser. The Issuers shall
furnish to the Purchaser such conformed copies of such opinions, certificates,
letters, schedules, documents and instruments in such quantities as the
Purchaser shall reasonably request.

                  The acceptance of the proceeds of each issuance of Securities
shall constitute a representation and warranty by each of the Issuers to the
Purchaser that all the conditions specified in this Section 6 were satisfied as
of such Closing Date (unless otherwise waived by the Purchaser).

                  7. Indemnification and Contribution. (a) Each Issuer jointly
and severally agrees to indemnify and hold harmless the Purchaser, each
director, officer, employee or agent of the Purchaser and each person, if any,
who controls the Purchaser within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, against any losses, claims, damages,
liabilities or expenses to which the Purchaser or such director, officer,
employee, agent or controlling person may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) arise out of or are
based:

                  (i) in whole or in part upon any inaccuracy of any of the
         representations and warranties of the Issuers contained herein; or

                  (ii) upon the failure of the Issuers to perform their
         respective agreements or obligations hereunder or under any other
         Transaction Document,

and will reimburse, promptly after demand, the Purchaser and each such director,
officer, employee, agent or controlling person for any legal or other expenses
reasonably incurred by the Purchaser or such director, officer, employee, agent
or controlling person in connection with investigating, defending against or
appearing as a third-party witness in connection with any such loss, claim,
damage, liability, expense or action. This indemnity agreement will be in
addition to any liability that the Issuers may otherwise have to the indemnified
parties. The Issuers further agree that the indemnification, contribution and
reimbursement commitments set forth in this
<PAGE>
                                      -24-

Section 7 shall apply whether or not the Purchaser is a formal party to any such
lawsuits, claims or other proceedings.

                  (b) The Purchaser will indemnify and hold harmless the
Issuers, their respective directors, officers, employees and agents and each
person, if any, who controls any of the Issuers within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act against any losses,
claims, damages or liabilities to which any of the Issuers or any such director,
officer, employee, agent or controlling person may become subject, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any inaccuracy of any of the Purchaser's
representations and warranties contained herein and will reimburse, promptly
after request, any legal or other expenses reasonably incurred by any of the
Issuers or any such director, officer, employee, agent or controlling person in
connection with investigating or defending against or appearing as a third-party
witness in connection with any such loss, claim, damage, liability or action in
respect thereof. This indemnity agreement will be in addition to any liability
that the Purchaser may otherwise have to the indemnified parties.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 7, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability that it may have to any indemnified party except to the extent
that such omission results in the forfeiture by the indemnifying party of
substantial rights and defenses. In case any such action is brought against any
indemnified party, and such indemnified party notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party; provided, however, that if the named
parties in any such action (including any impleaded parties) include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties that are different from or additional to
those available to any such indemnifying party, and a conflict of interest may
exist between an indemnified party and the indemnifying party and the
representation of both would be inappropriate, then the indem-
<PAGE>
                                      -25-

nifying parties shall not have the right to direct the defense of such action on
behalf of such indemnified party or parties and such indemnified party or
parties shall have the right to select separate counsel to defend such action on
behalf of such indemnified party or parties. After notice from the indemnifying
party to such indemnified party of its election so to assume the defense thereof
and approval by such indemnified party of counsel appointed to defend such
action, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or other expenses, other than reasonable
out-of-pocket costs of investigation, incurred by such indemnified party in
connection with the defense thereof, unless (i) the indemnified party shall have
employed separate counsel in accordance with the proviso to the immediately
preceding sentence (it being understood, however, that in connection with such
action the indemnifying party shall not be liable for the expenses of more than
one separate counsel (in addition to local counsel) in any one action or
separate but substantially similar actions in the same jurisdiction arising out
of the same general allegations or circumstances, representing the indemnified
parties under such paragraph (a) or paragraph (b), as the case may be, who are
parties to such action or actions); (ii) the indemnifying party has authorized
in writing the employment of counsel for the indemnified party at the expense of
the indemnifying parties; or (iii) the indemnifying party shall have failed to
assume the defense or retain counsel reasonably satisfactory to the indemnified
party. After such notice from the indemnifying parties to such indemnified party
(so long as the indemnified party shall have informed the indemnifying parties
of such action in accordance with this Section 7 on a timely basis prior to the
indemnified party seeking indemnification hereunder), the indemnifying parties
will not be liable under this Section 7 for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party, unless such indemnified party waived its rights under
this Section 7, in which case the indemnified party may effect such a settlement
without such consent. No indemnifying party will, without the prior written
consent of the indemnified party (which shall not be unreasonably withheld or
delayed), settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification by an indemnified party may be sought hereunder (whether or not
the indemnified party or any person who controls any indemnified party within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act is a party to such claim, action, suit or proceeding), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indem-
<PAGE>
                                      -26-

nified party and each such director, officer, employee, agent or controlling
person from all liability arising out of such claim, action, suit or proceeding
and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act as to any such person.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 7 is unavailable or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages,
expenses or liabilities (or actions in respect thereof), each indemnifying
party, in order to provide for just and equitable contribution, shall contribute
to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages, expenses or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect (i) the relative benefits
received by the Issuers on the one hand and the Purchaser on the other from the
offering of the Securities or (ii) if the allocation provided by the foregoing
clause (i) is not permitted by applicable law, not only such relative benefits
but also the relative fault of the indemnifying party or parties on the one hand
and the indemnified party on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages, expenses or liabilities (or actions in respect thereof). The
relative benefits received by the Issuers on the one hand and the Purchaser on
the other shall be deemed to be in the same proportion as the total proceeds
from the offering of the Securities (before deducting expenses) received by the
Issuers bear to the total fees received by the Purchaser. The relative fault of
the parties shall be determined by reference to, among other things, whether the
inaccuracy or failure relates to the Issuers on the one hand or the Purchaser on
the other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such inaccuracy or failure, and any other
equitable considerations appropriate in the circumstances. The amount paid or
payable by a party as a result of the losses, claims, damages and liabilities
referred to above shall be deemed to include any legal or other fees or expenses
incurred by such party in connection with investigating or defending any such
claim. The Issuers and the Purchaser agree that it would not be equitable if the
amount of such contribution were determined by pro rata or per capita allocation
(even if the Issuers on the one hand and the Purchaser on the other hand were
treated as one entity for such purpose) or by any other method of allocation
that does not take into account the equitable considerations referred to in the
first sentence of this paragraph (d). Notwithstanding any other provision of
<PAGE>
                                      -27-

this paragraph (d), the Purchaser shall not be obligated to make contributions
hereunder that in the aggregate exceed the total fees received by the Purchaser
under this Agreement, less the aggregate amount of any damages that the
Purchaser has otherwise been required to pay hereunder, and no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this paragraph (d),
each director, officer, employee or agent of and each person, if any, who
controls the Purchaser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as the
Purchaser, and each director, officer, employee and agent of any of the Issuers
and each person, if any, who controls any of the Issuers within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as the Issuers.

                  (e) Notwithstanding anything to the contrary in this Section
7, the indemnification and contribution provisions of the Registration Rights
Agreement and the Engagement Letter shall govern any claim with respect thereto.

                  8. Offering of Securities; Restrictions on Transfer. The
Purchaser represents and warrants (i) that it is a QIB, (ii) that the Notes
Issuers have (x) made available to the Purchaser or its representatives all
agreements, documents, records and books that the Purchaser has requested
relating to an investment in the Securities, (y) the Purchaser has had an
opportunity to ask questions of, and receive answers from, Persons acting on
behalf of the Issuers concerning the terms and conditions of this investment and
(z) the Purchaser has such knowledge and experience in financial and business
matters that it is capable of evaluating the risks and merits of its investments
in the Securities, (iii) that it has the requisite corporate power and authority
to execute, deliver and perform its obligations under this Agreement and the
Registration Rights Agreement and (iv) that this Agreement and the Registration
Rights Agreement have been duly and validly authorized by the Purchaser and when
executed and delivered by the Purchaser (assuming due authorization execution
and delivery by the Issuers), will each constitute a valid and legally binding
agreement of the Purchaser, enforceable against the Purchaser in accordance with
its terms except (a) that the enforcement thereof may be limited by the
Enforceability Exceptions and (b) as any rights to indemnity or contribution
hereunder may be limited by federal and state securities laws and public policy
considera-
<PAGE>
                                      -28-

tions. The Purchaser agrees with the Issuers that (i) it has not and will not
solicit offers for, or offer or sell, the Securities by any form of general
solicitation or general advertising (as those terms are used in Regulation D
under the Securities Act) or in any manner involving a public offering within
the meaning of Section 4(2) of the Securities Act; and (ii) the Securities may
be transferred by the Purchaser only if a subsequent disposition thereof is
registered or qualified under the Securities Act and applicable state securities
laws or is exempt from such registration or qualification.

                  9. Survival Clause. The respective representations,
warranties, agreements, covenants, indemnities and other statements of the
Issuers, their respective officers and the Purchasers set forth in this
Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement shall remain in full force and effect, regardless of (i) any
investigation made by or on behalf of the Issuers, any of their respective
officers or directors, the Purchaser or any controlling person referred to in
Section 7 hereof and (ii) delivery of and payment for the Securities, and shall
be binding upon and shall inure to the benefit of, any successors, assigns,
heirs, personal representatives of the Issuers, the Purchaser and indemnified
parties referred to in Section 7 hereof. The respective agreements, covenants,
indemnities and other statements set forth in Sections 4, 5 and 7 hereof shall
remain in full force and effect, regardless of any termination or cancellation

                  10. Termination. (a) This Agreement may be terminated (i) in
the sole discretion of the Purchaser by notice to the Issuers given in the event
that the Issuers shall have failed, refused or been unable to satisfy all
conditions on their part to be performed or satisfied hereunder on or prior to

Purchaser or, (iii) in the sole discretion of the Purchaser by notice to the
Issuers if at or prior to any Closing Date:

                           (A) any of the Issuers shall have sustained any loss
         or interference with respect to their respective businesses or

         calamity, whether or not covered by insurance, or from any labor
         dispute or any legal or governmental proceeding, which loss or
         interference has had or has a Material Adverse Effect or there shall
         have been any material adverse change, or any development involving a

         financial markets of the United States that, in the sole judgment of
         the Purchaser, makes it impracticable or inadvisable to proceed with
         the offering or the delivery of the Securities as contemplated by this
         Agreement; or

                           (E) any securities of the Issuers shall have been

Ladies and Gentlemen:

     We have acted as special legal counsel to Muzak LLC, formerly known as
Audio Communications Network, LLC, a Delaware limited liability company
(the "Company") and Muzak Finance Corp., a Delaware corporation ("Finance Corp."
and, together with the Company, the "Notes Issuers"). This letter is being
provided in response to the requirement in Section 6(i) of the Purchase
Agreement dated February 2, 2000 (the "Purchase Agreement"), by and among the
Notes Issuers, the subsidiaries named therein and CIBC Inc. (the "Purchaser")
relating to the purchase from time to time by the Purchaser of up to $50,000,000
in principal amount of notes (the "Notes") issued by the Notes Issuers. All
capitalized terms used herein and not defined herein shall have the meanings
given to such terms in the Purchase Agreement. Together, the Purchase Agreement,
the Indenture, the Registration Rights Agreement, the Notes, the Muzak Capital
Guarantee, the BI Guarantee and the Holdings Guarantee (each as defined below)
are referred to herein as the "Transaction Documents."

     In connection with the preparation of this letter, we have among other
things read:

     (a)  an executed original of the Purchase Agreement;

     (b)  executed originals of the Indenture and the Notes to be delivered on
          the date hereof, the Guarantee of the Notes (the "Muzak Capital
          Guarantee") by Muzak Capital Corporation, a Delaware corporation
          ("Muzak Capital"), the Guarantee of the Notes (the "BI Guarantee") by
          BI Acquisition, L.L.C., a Delaware limited liability company ("BI
          Acquisition") and the Guarantee of the Notes (the "Holdings
          Guarantee") by Muzak Holdings LLC ("Holdings" and, together with

          Muzak Capital, BI Acquisition and the Notes Issuers, the "Issuers"),
          the sole member of the Company;

     (c)  an executed original of the Registration Rights Agreement;

     (d)  copies of all certificates and other documents delivered on the date
          hereof in connection with the sale of the Notes on the date hereof and
          the consummation of the other transactions contemplated by the
          Purchase Agreement; and

     (e)  such other records, certificates and documents as we have deemed
          necessary or appropriate in order to deliver the opinions set forth
          herein

     In preparing this letter, we have relied without any independent
verification upon the assumptions recited in Schedule B to this letter and upon:
(i) information contained in certificates obtained from governmental
authorities; (ii) factual information represented to be true in the Purchase
Agreement and the other Transaction Documents; (iii) factual information
provided to us in the Support Certificate signed by the Notes Issuers and
attached hereto, and (iv) factual information we have obtained from such other
sources as we have deemed reasonable. We have assumed without investigation that
there has been no relevant change or development between the dates as of which
the information cited in the preceding sentence was given and the date of this
letter and that the information upon which we have relied is accurate and does
not omit disclosures necessary to prevent such information from being
misleading. For purposes of each opinion in paragraph 1, we have relied
exclusively upon certificates issued by a governmental authority in each
relevant jurisdiction, and such opinion is not intended to provide any
conclusion or assurance beyond that conveyed by that certificate.

     While we have not conducted any independent investigation to determine
facts upon which our opinions are based or to obtain information about which
this letter advises you, we confirm that we do not have any actual knowledge
which has caused us to conclude that our reliance and assumptions cited in the
preceding paragraph are unwarranted or that any information supplied in this
letter is wrong.  The term "actual knowledge" whenever it is used in this letter
with respect to our firm means conscious awareness at the time this letter is
delivered on the date it bears by the following Kirkland & Ellis lawyers, who
constitute all of the Kirkland & Ellis lawyers who have devoted a significant
amount of time to the negotiation or preparation of the Transaction Documents,
and the due diligence associated therewith (herein called "our Designated
Transaction Lawyers"): Laurie T. Gunther and Lisa M. Anastos.

     Subject to the assumptions, qualifications, exclusions and other
limitations which are identified in this letter and in the schedules attached
to this letter, we advise you that:

     thereto) is enforceable against each of them (to the extent each is a
     party thereto) in accordance with its terms.

7.   When the Notes are issued and paid for by the Purchaser in accordance with
     the terms of the Purchase Agreement (assuming the due authorization,
     execution and delivery of the Indenture by the Trustee and due
     authentication and delivery of such Notes by the Trustee in accordance with
     the Indenture), such Notes and the Guarantees will constitute the valid
     and binding obligations of the Issuers (to the extent each is a party
     thereto), enforceable against each of them (to the extent each is a party
     thereto) in accordance with their terms and entitled to the benefits of
     the Indenture. The Notes to be delivered on the date hereof are in the

     due authentication and delivery of the Exchange Notes and the Private
     Exchange Notes by the Trustee in accordance with the Indenture, and the due

     due authentication and delivery of such Additional Notes by the Trustee in

     thereon will constitute the valid and binding obligations of the Issuers
     (to the extent each is a party thereto), enforceable against each of them
     (to the extent each is a party thereto) in accordance with their terms and

10.  The execution and delivery of the Transaction Documents and the
     consummation of the transactions contemplated thereby (including,
     without limitation, the issuance and sale of the Notes to the Purchaser)
     do not and will not conflict with or constitute or result in a breach
     or default under (or an event which with notice or the passage of time or
     both would constitute a default under) or violation of any of, (i) the
     Limited Liability Company Agreement of the Company, BI Acquisition or
     Holdings, (ii) the certificate of

     incorporation or bylaws of Finance Corp. or Muzak Capital, (iii) any
     statute or governmental rule or regulation which, in our experience, is
     normally applicable both to general business corporations that are not
     engaged in regulated business activities and to transactions of the type
     contemplated by the Purchase Agreement (but without our having made any
     special investigation as to other laws and provided that we express no
     opinion in this paragraph with respect to (a) any laws, rules or
     regulations to which the Company or Muzak Capital may be subject as a
     result of the Purchaser's legal or regulatory status or the involvement of
     the Purchaser in such transactions, (b) any laws, rules or regulations
     relating to disclosure, misrepresentations or fraud, (c) the Act, the
     Exchange Act or the Trust Indenture Act of 1939 ("TIA") or (d) regulatory
     issues (other than those relating to federal securities laws) that may be
     applicable to the Notes Issuers by virtue of the nature of their business)
     or (iv) with the exception of the payment of additional interest on the
     Notes provided for in Section 4 of the Registration Rights Agreement, the
     terms or provisions of any contract set forth on Schedule C attached
     hereto, except for any such conflict, breach, violations, default or event
     which would not, individually or in the aggregate, reasonably be expected
     to have a Material Adverse Effect and except for any such conflict, breach,
     violation or default which has been waived by the party or parties with
     the power to waive such conflict, breach, violation or default.

11.  To our actual knowledge, no consent, waiver, approval, authorization or
     order of any court or governmental authority is required for the issuance
     and sale by the Company or Finance Corp. of the Notes to the Purchaser, the
     issuance of the Muzak Capital Guarantee by Muzak Capital, the issuance of
     the BI Guarantee by BI Acquisition, the issuance of the Holdings Guarantee
     by Holdings or the consummation by the Issuers of the other transactions
     contemplated by the Transaction Documents, except such as may be required
     under the Act, the Exchange Act, the TIA, the securities or Blue Sky laws
     of the various states (and the rules and regulations thereunder), and
     authority that may be applicable to the Notes Issuers by virtue of the
     nature of their business, as to which we express no opinion in this
     paragraph.

12.  To our actual knowledge, no legal or governmental proceedings are pending
     to which the Company of Finance Corp. is a party or to which the property
     or assets of the Company or Finance Corp. is subject which seek to
     restrain, enjoin or prevent the consummation of or otherwise challenge the
     issuance or sale of the Notes to be sold to the Purchaser or the
     consummation of the other transactions contemplated by the Transaction
     Documents.

13.  No registration under the Act of the Notes is required in connection with
     the sale of the Notes to the Purchaser in the manner contemplated by the
     Purchase Agreement and prior to the commencement of the Exchange Offer or
     the effectiveness of the Shelf Registration Statement (as defined in the
     Registration Rights Agreement), the Indenture is not required

     to be qualified under the TIA, in each case assuming the accuracy and
     completeness of the Purchaser's representations in Section 8 and those
     of the Issuers contained in the Purchase Agreement regarding the absence
     of a general solicitation in connection with the sale of such Notes to
     the Purchaser.

14.  As of the date hereof, the Notes are not of the same class (within the
     meaning of Rule 144A under the Act) as securities of the Company or Finance
     Corp. that are listed on a national securities exchange registered under
     Section 6 of the Exchange Act or that are quoted in a United States
     automated inter-dealer quotation system.

15.  Neither the Company nor Finance Corp. is, or immediately after the sale of
     the Notes to the Purchaser will be, an "investment company" as such term is
     defined in the Investment Company Act of 1940, as amended.

16.  Neither the sale, issuance, execution or delivery of the Notes will
     contravene Regulation T (12 C.F.R. Part 220), Regulation U (12 C.F.R. Part
     221) or Regulation X (12 C.F.R. Part 224) of the Board of Governors of the
     Federal Reserve System.

     Our advice on every legal issue addressed in this letter is based
exclusively on the internal law of New York or the federal law of the United
States except that certain of the opinions in paragraphs 1 through 5, the first
clause of paragraph 7, and paragraph 10 are based on the Delaware Limited
Liability Company Act (in the case of the Company, BI Acquisition and Holdings)
and the Delaware General Corporation Law (in the case of Finance Corp. and Muzak
Capital). Issues addressed by this letter may be governed in whole or in part by
other laws, but we express no opinion as to whether any relevant difference
exists between the laws upon which our opinions are based and any other laws
which may actually govern. Our opinions are subject to all qualifications in
Schedule A and do not cover or otherwise address any provision in the Purchase
Agreement or any of the other Transaction Documents of any type identified in
Schedule E. Furthermore, our opinion expressed in paragraph 10 does not cover
or otherwise address any law or legal issue which is identified in the attached
Schedule D. Provisions in the Transaction Documents which are not excluded by
Schedule E or any other part of this letter or its attachments are called the
"Relevant Agreement Terms."

     Our advice on each legal issue addressed in this letter represents our
opinion as to how that issue would be resolved were it to be considered by the
highest court of the jurisdiction upon whose law our opinion on that issue is
based. The manner in which any particular issue would be treated in any actual
court case would depend in part on facts and circumstances particular to

the case, and this letter is not intended to guarantee the outcome of any legal
dispute which may arise in the future.  It is possible that some Relevant
Agreement Terms may not prove enforceable for reasons other than those cited in
this letter should an actual enforcement action be brought, but (subject to all
the exceptions, qualifications, exclusions and other limitations contained in
this letter) such unenforceabilty would not in our opinion prevent you from
realizing the principal benefits purported to be provided by the Relevant
Agreement Terms.

     For purposes of rendering our opinions set forth in paragraph 9 above, we
have assumed that at the time of the issuance and delivery of the Additional
Notes (x) the authorization of the Additional Notes by the Issuers (to the
extent each is a party thereto) will not have been modified or rescinded, and
there will not have occurred any change in law affecting the validity, legally
binding character or enforceability of the Additional Notes and (y) the issuance
and delivery of the Additional Notes, the terms of the Additional Notes, the
terms of any agreement, any supplemental indenture to the Indenture, and
compliance by the Issuers to the extent each is a party thereto) with the terms
of the Additional Notes and the terms of any such agreement or indenture will
not violate any applicable law, any agreement or instrument then binding upon
the Issuers (to the extent each is a party thereto) or any restriction imposed
by any court or governmental body having jurisdiction over the Issuers (to the
extent each is a party thereto).

     This letter speaks as of the time of its delivery on the date it bears. We
do not assume any obligation to provide you with any subsequent opinion or
advice by reason of any fact about which our Designated Transaction Lawyers did
not have actual knowledge at that time, by reason of any change subsequent to
that time in any law covered by any of our opinions, or for any other reason.
The attached schedules are an integral part of this letter, and any term
defined in this letter or any schedule has that defined meaning wherever it is
used in this letter or in any schedule to this letter.

                                   Schedule A

                             General Qualifications

     All of our opinions ("our opinions") in the letter to which this Schedule
is attached ("our letter") are subject to each of the qualifications set forth
in this Schedule.

1.   Bankruptcy and Insolvency Exception. Each of our opinions is subject to the
     effect of:

     a.   all Federal and state bankruptcy, insolvency, reorganization,
          receivership, moratorium and other laws that affect the rights of
          creditors generally or that have reference to or affect only creditors
          of specific types of debtors (which comprehends, among others, matters
          of turn-over, automatic stay, avoiding powers, preference, discharge,
          conversion of a non-recourse obligation into a recourse claim,
          limitations on IPSO FACTO and anti-assignment clauses and the coverage
          of pre-petition security agreements applicable to property acquired
          after a petition is filed);

     b.   fraudulent transfer and conveyance laws; and

     c.   judicially developed doctrines in this area, such as substantive
          consolidation of entities and equitable subordination.

2.   Equitable Principles Limitation. Each of our opinions is subject to the
     effect of general principles of equity, whether applied by a court of law
     or equity. This limitation includes principles:

     a.   governing the availability of specific performance, injunctive relief
          or other equitable remedies, which generally place the award of such
          remedies, subject to certain guidelines, in the discretion of the
          court to which application for such relief is made;

     b.   affording equitable defenses (e.g., waiver, laches and estoppel)
          against a party seeking enforcement;

     c.   requiring good faith and fair dealing in the performance and
          enforcement of a contract by the party seeking its enforcement;

     d.   requiring reasonableness in the performance and enforcement of an
          agreement by the party seeking enforcement of the contract;

     e.   requiring consideration of the materiality of (i) a breach and (ii)
          the consequences of the breach to the party seeking enforcement;


                                      A-1

<PAGE>

     f.   requiring consideration of the impracticability or impossibility of
          performance at the time of attempted enforcement; and

     g.   affording defenses based upon the unconscionability of the enforcing
          party's conduct after the parties have entered into the contract.

3.   Other Common Qualifications. Each of our opinions is subject to the effect
     of rules of law that:

     a.   limit the availability of a remedy under certain circumstances where
          another remedy has been elected;

     b.   provide a time limitation after which a remedy may not be enforced;

     c.   limit the enforceability of provisions releasing, exculpating or
          exempting a party from, or requiring indemnification of a party for,
          liability for its own action or inaction, to the extent the action or
          inaction involves negligence, violation of public policy or litigation
          against another party determined adversely to such party;

     d.   may, where less than all of a contract may be unenforceable, limit the
          enforceability of the balance of the contract to circumstances in
          which the unenforceable portion is not an essential part of the agreed
          exchange;

     e.   govern and afford judicial discretion regarding the determination of
          damages and entitlement to attorneys' fees and other costs;

     f.   may permit a party that has materially failed to render or offer
          performance required by the contract to cure that failure unless (i)
          permitting a cure would unreasonably hinder the aggrieved party from
          making substitute arrangements for performance, or (ii) it was
          important in the circumstances to the aggrieved party that performance
          occur by the date stated in the contract; and

     g.   may render waivers of suretyship defenses ineffective under certain
          circumstances.

4.   Referenced Provision Qualification. In addition, our opinions, insofar as
     they relate to the validity, binding effect or enforceability of a
     provision in any of the Transaction Documents requiring any Issuer to
     perform its obligations under, or to cause any other person to perform its
     obligations under, any provision (a "Referenced Provision") of such
     Transaction Document or of any of the other Transaction Documents or
     stating that any

                                      A-2

<PAGE>

     action will be taken as provided in or in accordance with any provision
     (also a "Referenced Provision") of any other Transaction Document, are
     subject to the same qualifications as the corresponding opinion in this
     letter relating to the validity, binding effect and enforceability of such
     Referenced Provision. Requirements in the Transaction Documents that
     provisions therein may only be waived or amended in writing may not be
     enforceable to the extent that an oral agreement or an implied agreement
     by trade practice or course of conduct has been created modifying any
     such provision.

5.   Cross-Default Provisions. With respect to our opinion in paragraph 10
     above, we express no opinion with respect to violations under cross-default
     provisions referring to or based upon agreements that are not included on
     Schedule C or with respect to compliance with financial covenants or tests
     contained in any agreement listed on Schedule C. For purposes of the
     preceding sentence, agreements which are attached as exhibits, schedules
     or attachments to or are otherwise referred to in agreements listed on
     Schedule C, but are not directly listed on Schedule C, shall not be deemed
     to be included on Schedule C.

                                   Schedule B

                                  Assumptions

     For purposes of our letter, we have relied, without investigation, upon
each of the following assumptions:

1.   The Purchaser has purchased and will purchase the Notes pursuant to the
     Purchase Agreement and has paid and will pay the consideration therefor to
     the Note Issuers.

2.   With respect to the enforceability of any Transaction Document by any party
     other than the Issuers, such other party or parties, as the case may be,
     has satisfied those legal requirements that are applicable to each to the
     extent necessary to entitle each such person to enforce the Transaction
     Documents to which it is a party against the Issuers.

3.   Each document submitted to us for review is accurate and complete, each
     such document that is an original is authentic, each such document that is
     a copy conforms to an authentic original, and all signatures (other than
     those of or on behalf of the Issuers) on each such document are genuine.

4.   There has not been any mutual mistake of fact or misunderstanding, fraud,
     duress or undue influence.

5.   There are no agreements or understandings among the parties, written or
     oral, and there is no usage of trade or course or prior dealing among the
     parties that would, in either case, define, supplement or qualify the terms
     of the Purchase Agreement or any of the other Transaction Documents.

6.   All agreements (if any) (other than the Transaction Documents) with respect
     to which we have provided advice in our letter or reviewed in connection
     with our letter would be enforced as written.

7.   All information required to be disclosed in connection with any consent or
     approval by the Board of Directors or Sole Manager of any Issuer and all
     other information required to be disclosed in connection with any issue
     relevant to our opinions has in fact been fully and fairly disclosed to all
     persons to whom it is required to be disclosed.

8.   Each person who has taken any action relevant to any of our opinions in the
     capacity of director or officer was duly elected to that director or
     officer position and held that position when such action was taken.

                  (a) Each of the Issuers agrees to file with the Commission no
later than the Filing Date, an offer to exchange
<PAGE>
                                      -6-

(the "Exchange Offer") any and all of the Registrable Notes (other than Private
Exchange Notes, if any) for a like aggregate principal amount of debt securities
of the Notes Issuers which are identical in all material respects to the Notes
(the "Exchange Notes") (and which are entitled to the benefits of the Indenture
or a trust indenture which is identical in all material respects to the
Indenture (other than such changes to the Indenture or any such identical trust
indenture as are necessary to comply with any requirements of the Commission to
effect or maintain the qualification thereof under the TIA) and which, in either
case, has been qualified under the TIA and which shall also be entitled to the
benefits of the Guarantees of the Guarantors), except that the Exchange Notes
shall have been registered pursuant to an effective Registration Statement under
the Securities Act and shall contain no restrictive legend thereon. The Exchange
Offer shall be registered under the Securities Act on the appropriate form (the
"Exchange Registration Statement") and shall comply with all applicable tender
offer rules and regulations under the Exchange Act. Each of the Issuers agrees
to use its reasonable best efforts to (x) cause the Exchange Registration
Statement to be declared effective under the Securities Act on or before the
Effectiveness Date; (y) keep the Exchange Offer open for at least 30 days (or
longer if required by applicable law) after the date that notice of the Exchange
Offer is first mailed to Holders; and (z) consummate the Exchange Offer on or
prior to the 60th day following the date on which the Exchange Registration
Statement is declared effective. If after such Exchange Registration Statement
is initially declared effective by the Commission, the Exchange Offer or the
issuance of the Exchange Notes thereunder is interfered with by any stop order,
injunction or other order or requirement of the Commission or any other
governmental agency or court, such Exchange Registration Statement shall be
deemed not to have become effective for purposes of this Agreement. Each Holder
who participates in the Exchange Offer will be required to represent that any
Exchange Notes received by it will be acquired in the ordinary course of its
business, that at the time of the consummation of the Exchange Offer such Holder
will have no arrangement or understanding with any Person to participate in the
distribution of the Exchange Notes, that such Holder is not an affiliate of any
Issuer within the meaning of the Securities Act, and any additional
representations that in the written opinion of counsel to the Issuers are
necessary under then-existing interpretations of
<PAGE>
                                      -7-

the Commission in order for the Exchange Registration Statement to be declared
effective. Upon consummation of the Exchange Offer in accordance with this
Section 2, the provisions of this Agreement shall continue to apply, mutatis
mutandis, solely with respect to Registrable Notes that are Private Exchange
Notes and Exchange Notes held by Participating Broker-Dealers, and the Issuers
shall have no further obligation to register Registrable Notes (other than
Private Exchange Notes and other than in respect of any Exchange Notes as to
which clause 2(c)(iv) hereof applies) pursuant to Section 3 of this Agreement.

                  (b) The Issuers shall include within the Prospectus contained
in the Exchange Registration Statement a section entitled "Plan of
Distribution," reasonably acceptable to the Purchaser, which shall contain a
summary statement of the positions taken or policies made by the Staff of the
Commission with respect to the potential "underwriter" status of any
broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the
Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange
Offer (a "Participating Broker-Dealer"), whether such positions or policies have
been publicly disseminated by the Staff of the Commission or such positions or
policies, in the reasonable judgment of the Purchaser, represent the prevailing
views of the Staff of the Commission. Such "Plan of Distribution" section shall
also allow, to the extent permitted by applicable policies and regulations of
the Commission, the use of the Prospectus by all Persons subject to the
prospectus delivery requirements of the Securities Act, including, to the extent
so permitted, all Participating Broker-Dealers, and include a statement
describing the manner in which Participating Broker-Dealers may resell the
Exchange Notes.

                  Each of the Issuers shall use its reasonable best efforts to
keep the Exchange Registration Statement effective and to amend and supplement
the Prospectus contained therein, in order to permit such Prospectus to be
lawfully delivered by all Persons subject to the prospectus delivery
requirements of the Securities Act for such period of time, not to exceed 180
days from the date the Exchange Offer is consummated, as such Persons must
comply with such requirements in connection with offers and sales of the
Exchange Notes (the "Applicable Period").
<PAGE>
                                      -8-

                  If, upon consummation of the Exchange Offer, the Purchaser
holds any Notes acquired by it and having the status of an unsold allotment in
an initial distribution, the Issuers upon the request of the Purchaser shall,
simultaneously with the delivery of the Exchange Notes in the Exchange Offer,
issue and deliver to the Purchaser, in exchange (the "Private Exchange") for the
Notes held by the Purchaser, a like principal amount of debt securities of the
Notes Issuers that are identical in all material respects to the Exchange Notes
except for the existence of restrictions on transfer thereof under the
Securities Act and securities laws of the several states of the U.S. (the
"Private Exchange Notes") (and which are issued pursuant to the same indenture
as the Exchange Notes and which will have the Guarantees of the Guarantors). The
Private Exchange Notes shall bear the same CUSIP number as the Exchange Notes.
Interest on the Exchange Notes and Private Exchange Notes will accrue from the
last interest payment date on which interest was paid on the Notes surrendered
in exchange therefor or, if no interest has been paid on the Notes, from the
dates of original issuance of the Notes.

                  In connection with the Exchange Offer, the Issuers shall:

                    (1) mail to each Holder a copy of the Prospectus forming
         part of the Exchange Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                    (2) utilize the services of a depositary for the Exchange
         Offer with an address in the Borough of Manhattan, The City of New
         York, which may be the Trustee or an affiliate thereof;

                    (3) permit Holders to withdraw tendered Registrable Notes at
         any time prior to the close of business, New York time, on the last
         Business Day on which the Exchange Offer shall remain open; and

                  (4) otherwise comply in all material respects with all
         applicable laws.

                  As soon as practicable after the close of the Exchange Offer
or the Private Exchange, as the case may be, the Issuers shall:
<PAGE>
                                      -9-

                    (1) accept for exchange all Registrable Notes validly
         tendered and not validly withdrawn pursuant to the Exchange Offer or
         the Private Exchange;

                  (2) deliver to the Trustee for cancellation all Registrable
         Notes so accepted for exchange; and

                    (3) cause the Trustee to authenticate and deliver promptly
         to each Holder tendering such Registrable Notes, Exchange Notes or
         Private Exchange Notes, as the case may be, equal in principal amount
         to the Notes of such Holder so accepted for exchange.

                  The Exchange Notes and the Private Exchange Notes may be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture, which in either event will provide that the Exchange
Notes will not be subject to the transfer restrictions set forth in the
Indenture and that the Exchange Notes, the Private Exchange Notes and the Notes,
if any, will vote and consent together on all matters as one class and that none
of the Exchange Notes, the Private Exchange Notes or the Notes, if any, will
have the right to vote or consent as a separate class on any matter.

                  (c) If, (i) because of any change in law or in currently
prevailing interpretations of the staff of the Commission, the Notes Issuers are
not permitted to effect an Exchange Offer, (ii) the Exchange Offer is not
consummated within 270 days of the Conversion Date, (iii) any holder of Private
Exchange Notes so requests in writing to the Company or (iv) in the case of any
Holder that participates in the Exchange Offer (and tenders its Registrable
Notes prior to the expiration thereof), such Holder does not receive Exchange
Notes on the date of the exchange that may be sold without restriction under
federal securities laws (other than due solely to the status of such Holder as
an affiliate of any Issuer within the meaning of the Securities Act) and so
notifies the Company within 30 days following the consummation of the Exchange
Offer (and providing a reasonable basis for its conclusions), in the case of
each of clauses (i)-(iv), then the Issuers shall promptly deliver to the Holders
and the Trustee written notice thereof (the "Shelf Notice") and shall file a
Shelf Registration pursuant to Section 3.

                                      -10-

3. Shelf Registration

                  If a Shelf Notice is delivered as contemplated by Section
2(c), then:

                  (a) Shelf Registration. The Issuers shall as promptly as
reasonably practicable file with the Commission a Registration Statement for an
offering to be made on a continuous basis pursuant to Rule 415 covering all of
the Registrable Notes (the "Initial Shelf Registration"). If the Issuers shall
not have yet filed the Exchange Registration Statement, each of the Issuers
shall use its reasonable best efforts to file with the Commission the Initial
Shelf Registration on or prior to the Filing Date and shall use its reasonable
best efforts to cause such Initial Shelf Registration to be declared effective
under the Securities Act on or prior to the Effectiveness Date applicable to the
Exchange Registration Statement. Otherwise, each of the Issuers shall file with
the Commission the Initial Shelf Registration within 150 days of the delivery of
the Shelf Notice and shall use its reasonable best efforts to cause such Shelf
Registration to be declared effective under the Securities Act on or prior to
the Effectiveness Date. The Initial Shelf Registration shall be on Form S-1 or
another appropriate form permitting registration of such Registrable Notes for
resale by Holders in the manner or manners designated by them (including,
without limitation, one or more underwritten offerings). The Issuers shall not
permit any securities other than the Registrable Notes to be included in any
Shelf Registration. Each of the Issuers shall use its reasonable best efforts to
keep the Initial Shelf Registration continuously effective under the Securities
Act until the date which is 24 months from the effective date of such Initial
Shelf Registration (or, if Rule 144(k) under the Securities Act is amended to
permit unlimited resales by non-affiliates within a lesser period, such lesser
period) (subject to extension pursuant to the last paragraph of Section 5
hereof) (the "Effectiveness Period") or such shorter period ending when (i) all
Registrable Notes covered by the Initial Shelf Registration have been sold in
the manner set forth and as contemplated in the Initial Shelf Registration or
(ii) a Subsequent Shelf Registration covering all of the Registrable Notes has
been declared effective under the Securities Act.

                                      -11-

                  (b) Subsequent Shelf Registrations. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), each of the Issuers shall
use its reasonable best efforts to obtain the prompt withdrawal of any order
suspending the effectiveness thereof, and in any event shall within 45 days of
such cessation of effectiveness amend the Shelf Registration in a manner to
obtain the withdrawal of the order suspending the effectiveness thereof, or file
an additional "shelf" Registration Statement pursuant to Rule 415 covering all
of the Registrable Notes (a "Subsequent Shelf Registration"). If a Subsequent
Shelf Registration is filed, each of the Issuers shall use its reasonable best
efforts to cause the Subsequent Shelf Registration to be declared effective as
soon as practicable after such filing and to keep such Subsequent Shelf
Registration continuously effective for a period equal to the number of days in
the Effectiveness Period less the aggregate number of days during which the
Initial Shelf Registration or any Subsequent Shelf Registrations was previously
continuously effective. As used herein the term "Shelf Registration" means the
Initial Shelf Registration and any Subsequent Shelf Registration.

                  (c) Supplements and Amendments. Each of the Issuers shall
promptly supplement and amend any Shelf Registration if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration, if required by the Securities Act, or if reasonably
requested by the Holders of a majority in aggregate principal amount of the
Registrable Notes covered by such Shelf Registration or by any underwriter of
such Registrable Notes, in each case, with each Issuer's consent, which consent
shall not be unreasonably withheld or delayed.

4. Additional Interest

                  (a) The Issuers and the Purchaser agree that the Holders of
Registrable Notes will suffer damages if the Issuers fail to fulfill their
obligations under Section 2 or Section 3 hereof and that it would not be
feasible to ascertain the extent of such damages with precision. Accordingly,
each of the Issuers agrees to pay, as liquidated damages, additional interest on
the Registrable Notes ("Additional Interest") under
<PAGE>
                                      -12-

the circumstances and to the extent set forth below (each of which shall be
given independent effect):

                    (i) if (A) neither the Exchange Registration Statement nor
         the Initial Shelf Registration has been filed on or prior to the Filing
         Date or (B) notwithstanding that the Issuers have consummated or will
         consummate an Exchange Offer, the Issuers are required to file a Shelf
         Registration and such Shelf Registration is not filed on or prior to
         the 150th day after delivery of the Shelf Notice, then, in the case of
         subclause (A), commencing on the day after the Filing Date or, in the
         case of subclause (B), commencing on the 151st day following delivery
         of the Shelf Notice, Additional Interest shall accrue on the
         Registrable Notes over and above the stated interest at a rate of 0.50%
         per annum for the first 90 days immediately following the Filing Date
         or such 150th day, as the case may be, such Additional Interest rate
         increasing by an additional 0.25% per annum at the beginning of each
         subsequent 90-day period;

                   (ii) if (A) neither the Exchange Registration Statement nor
         the Initial Shelf Registration is declared effective on or prior to the
         Effectiveness Date applicable thereto or (B) notwithstanding that the
         Issuers have consummated or will consummate an Exchange Offer, the
         Issuers are required to file a Shelf Registration and such Shelf
         Registration is not declared effective by the Commission on or prior to
         the Effectiveness Date, then, commencing on the day after such
         applicable Effectiveness Date, Additional Interest shall accrue on the
         Registrable Notes over and above the stated interest at a rate of 0.50%
         per annum for the first 90 days immediately following the day after the
         applicable Effectiveness Date, such Additional Interest rate increasing
         by an additional 0.25% per annum at the beginning of each subsequent
         90-day period; and

                  (iii) if (A) the Issuers have not exchanged Exchange Notes for
         all Notes validly tendered in accordance with the terms of the Exchange
         Offer on or prior to 35 days after the date on which the Exchange
         Registration Statement was declared effective, (B) the Exchange
         Registration Statement ceases to be effective prior to consummation of
         the Exchange Offer or (C) if applicable, a Shelf Registration has been
         declared effective and such Shelf Registra-
<PAGE>
                                      -13-

         tion ceases to be effective at any time during the Effectiveness
         Period, then Additional Interest shall accrue on the Registrable Notes
         over and above the stated interest at a rate of 0.50% per annum for the
         first 90 days commencing on the (x) 36th day after such effective date
         in the case of (A) above or (y) the day such Exchange Registration
         Statement or Shelf Registration ceases to be effective in the case of
         (B) and (C) above, such Additional Interest rate increasing by an
         additional 0.25% per annum at the beginning of each such subsequent
         90-day period;

provided, however, that the Additional Interest rate on the Registrable Notes
may not exceed in the aggregate 2.0% per annum; provided further that (1) upon
the filing of the Exchange Registration Statement or each Shelf Registration (in
the case of (i) above), (2) upon the effectiveness of the Exchange Registration
Statement or each Shelf Registration, as the case may be (in the case of (ii)
above), or (3) upon the exchange of Exchange Notes for all Registrable Notes
validly tendered (in the case of (iii)(A) above) or upon the effectiveness of an
Exchange Registration Statement or Shelf Registration which had ceased to remain
effective (in the case of (iii)(B) and (C) above), Additional Interest on any
Registrable Notes then accruing Additional Interest as a result of such clause
(or the relevant subclause thereof), as the case may be, shall cease to accrue.

                  (b) The Issuers shall notify the Trustee within one business
day after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). Any amounts of
Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section
4 will be payable in cash quarterly on each regular interest payment date
specified in the Indenture (to the Holders of Registrable Notes of record on the
regular record date therefor (as specified in the Indenture) immediately
preceding such dates), commencing with the first such regular interest payment
date occurring after any such Additional Interest commences to accrue. The
amount of Additional Interest will be determined by multiplying the applicable
Additional Interest rate by the principal amount of the Notes subject thereto,
multiplied by a fraction, the numerator of which is the number of days such
Additional Interest rate was applicable during such period (determined on the
basis of a 360-day year and the actual days
<PAGE>
                                      -14-

elapsed occurring in the period for which payable) and the denominator of which
is 360.

5. Registration Procedures

                  In connection with the filing of any Registration Statement
pursuant to Sections 2 or 3 hereof, each Issuer shall effect such registrations
to permit the sale of such securities covered thereby in accordance with the
intended method or methods of disposition thereof, and pursuant thereto and in
connection with any Registration Statement filed by each Issuer hereunder, each
Issuer shall:

                  (a) Prepare and file with the Commission prior to the Filing
Date, the Exchange Registration Statement or if the Exchange Registration
Statement is not filed or is unavailable, a Shelf Registration as prescribed by
Section 2 or 3, and use its reasonable best efforts to cause each such
Registration Statement to become effective and remain effective as provided
herein; provided that, if (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period and has advised the Company that it is a Participating
Broker-Dealer, before filing any Registration Statement or Prospectus or any
amendments or supplements thereto, the Issuers shall, if requested, furnish to
and afford the Holders of the Registrable Notes to be registered pursuant to
such Shelf Registration or each such Participating Broker-Dealer, as the case
may be, covered by such Registration Statement, their counsel and the managing
underwriters, if any, a reasonable opportunity to review copies of all such
documents (including copies of any documents to be incorporated by reference
therein and all exhibits thereto) proposed to be filed (in each case, to the
extent practicable at least five Business Days prior to such filing). The
Issuers shall not file any such Registration Statement or Prospectus or any
amendments or supplements thereto if the Holders of a majority in aggregate
principal amount of the Registrable Notes covered by such Registration
Statement, or any such Participating Broker-Dealer, as the case may be, their
counsel, or the managing underwriters, if any, shall reasonably object.
<PAGE>
                                      -15-

                  (b) Prepare and file with the Commission such amendments and
post-effective amendments to each Shelf Registration or Exchange Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented by
any Prospectus supplement required by applicable law, and as so supplemented to
be filed pursuant to Rule 424 (or any similar provisions then in force) under
the Securities Act; and comply with the provisions of the Securities Act and the
Exchange Act applicable to it with respect to the disposition of all securities
covered by such Registration Statement as so amended or in such Prospectus as so
supplemented and with respect to the subsequent resale of any securities being
sold by a Participating Broker-Dealer covered by any such Prospectus. The
Issuers shall be deemed not to have used their reasonable best efforts to keep a
Registration Statement effective during the Applicable Period if they
voluntarily take any action that would result in selling Holders of the
Registrable Notes covered thereby or Participating Broker-Dealers seeking to
sell Exchange Notes not being able to sell such Registrable Notes or such
Exchange Notes during that period unless such action is required by applicable
law, rule or regulation or unless the Issuers comply with this Agreement,
including, without limitation, the provisions of paragraph 5(k) hereof and the
last paragraph of Section 5.

                  (c) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period from whom the Issuers have received written notice that it
will be a Participating Broker-Dealer, notify the selling Holders of Registrable
Notes, and each such Participating Broker-Dealer, their counsel and the managing
underwriters, if any, promptly (but in any event within two Business Days), and
confirm such notice in writing, (i) when a Prospectus or any Prospectus
supplement or post-effective amendment has been filed, and, with respect to a
Registration Statement or any post-effective amendment, when the same has become
effective (including in such notice a written statement that any Holder may,
upon request, obtain, without charge, one conformed copy of such Registration
Statement or post-effective
<PAGE>
                                      -16-

amendment including financial statements and schedules, documents incorporated
or deemed to be incorporated by reference and exhibits), (ii) of the issuance by
the Commission of any stop order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus or the initiation of any proceedings for that purpose, (iii) if at
any time when a prospectus is required by the Securities Act to be delivered in
connection with sales of the Registrable Notes the representations and
warranties of any Issuer contained in any agreement (including any underwriting
agreement contemplated by Section 5(n) hereof) cease to be true and correct in
any material respect, (iv) of the receipt by any Issuer of any notification with
respect to the suspension of the qualification or exemption from qualification
of a Registration Statement or any of the Registrable Notes or the Exchange
Notes to be sold by any Participating Broker-Dealer for offer or sale in any
jurisdiction, or the initiation or threatening of any proceeding for such
purpose, (v) of the happening of any event, the existence of any condition or
any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in, or amendments or supplements to,
such Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Issuers' reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate.

                  (d) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its reasonable best efforts to prevent the issuance of
any order suspending the effectiveness of a
<PAGE>
                                      -17-

Registration Statement or of any order preventing or suspending the use of a
Prospectus or suspending the qualification (or exemption from qualification) of
any of the Registrable Notes or the Exchange Notes to be sold by any
Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
order is issued, to use its reasonable best efforts to obtain the withdrawal of
any such order at the earliest possible date.

                  (e) If a Shelf Registration is filed pursuant to Section 3 and
if requested by the managing underwriters, if any, or the Holders of a majority
in aggregate principal amount of the Registrable Notes being sold in connection
with an underwritten offering, (i) as promptly as practicable incorporate in a
prospectus supplement or post-effective amendment such information or revisions
to information therein relating to such underwriters or selling Holders as the
managing underwriters, if any, or such Holders or their counsel reasonably
request to be included or made therein, (ii) make all required filings of such
prospectus supplement or such post-effective amendment as soon as practicable
after the Issuers have received notification of the matters to be incorporated
in such prospectus supplement or post-effective amendment, and (iii) supplement
or make amendments to such Registration Statement.

                  (f) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, furnish to each selling Holder of Registrable Notes and to
each such Participating Broker-Dealer who so requests and to counsel and each
managing underwriter, if any, without charge, one conformed copy of the
Registration Statement or Registration Statements and each post-effective
amendment thereto, including financial statements and schedules, and, if
requested, all documents incorporated or deemed to be incorporated therein by
reference and all exhibits.

                  (g) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer, deliver to each selling Holder of Registrable
<PAGE>
                                      -18-

Notes or each such Participating Broker-Dealer, as the case may be, their
respective counsel, and the underwriters, if any, without charge, as many copies
of the Prospectus or Prospectuses (including each form of preliminary
prospectus) and each amendment or supplement thereto and any documents
incorporated by reference therein as such Persons may reasonably request; and,
subject to the last paragraph of this Section 5, the Issuers hereby consent to
the use of such Prospectus and each amendment or supplement thereto by each of
the selling Holders of Registrable Notes and each Participating Broker-Dealer,
and the underwriters or agents, if any, and dealers (if any), in connection with
the offering and sale of the Registrable Notes covered by, or the sale by
Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus
and any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Registration Statement by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its reasonable best efforts to register or qualify, and
cooperate with the selling Holders of Registrable Notes and each such
Participating Broker-Dealer, the underwriters, if any, and their respective
counsel in connection with the registration or qualification (or exemption from
such registration or qualification) of such Registrable Notes or Exchange Notes,
as the case may be, for offer and sale under the securities or Blue Sky laws of
such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters, if any, reasonably
request in writing; provided that where Exchange Notes held by Participating
Broker-Dealers or Registrable Notes are offered pursuant to an underwritten
offering, counsel to the underwriters shall, at the reasonable cost and expense
of the Issuers, perform the Blue Sky investigations and file registrations and
qualifications required to be filed pursuant to this Section 5(h); keep each
such registration or qualification (or exemption therefrom) effective during the
period such Registration Statement is required to be kept effective and do any
and all other acts or things reasonably necessary or advisable to enable the
disposition in such jurisdictions of the Exchange Notes by Participating
Broker-Dealers or the Registrable Notes covered by the applicable Registration
Statement; provided that no Issuer shall be required to (A) qualify generally to
do business in any
<PAGE>
                                      -19-

jurisdiction where it is not then so qualified, (B) take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or (C) subject itself to taxation in excess of a nominal
dollar amount in any such jurisdiction where it is not then so subject.

                  (i) If a Shelf Registration is filed pursuant to Section 3,
cooperate with the selling Holders of Registrable Notes, any Participating
Broker-Dealer and the managing underwriter or underwriters, if any, to
facilitate the timely preparation and delivery of certificates representing
Registrable Notes to be sold, which certificates shall not bear any restrictive
legends and shall be in a form eligible for deposit with The Depository Trust
Company; and enable such Registrable Notes to be in such denominations and
registered in such names as the managing underwriter or underwriters, if any, or
Holders may reasonably request.

                  (j) Use its reasonable best efforts to cause the Registrable
Notes covered by the Registration Statement to be registered with or approved by
such governmental agencies or authorities as may be necessary to enable the
seller or sellers thereof or the underwriters, if any, to consummate the
disposition of such Registrable Notes, in which case the Issuers will cooperate
in all reasonable respects with the filing of such Registration Statement and
the granting of such approvals.

                  (k) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, upon the occurrence of any event contemplated by paragraph
5(c)(v) or 5(c)(vi) hereof, as promptly as reasonably practicable prepare and
(subject to Section 5(a) hereof) file with the Commission, at the Issuers' sole
expense, a supplement or post-effective amendment to the Registration Statement
or a supplement to the related Prospectus or any document incorporated or deemed
to be incorporated therein by reference, or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable Notes being
sold thereunder or to the purchasers of the Exchange Notes to whom such
Prospectus will be delivered by a Participating Broker-Dealer, any such
<PAGE>
                                      -20-

Prospectus will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

                  (l) Use its reasonable best efforts to cause the Registrable
Notes covered by a Registration Statement to be rated with the appropriate
rating agencies, if so requested by the Holders of a majority in aggregate
principal amount of Registrable Notes covered by such Registration Statement or
the managing underwriter or underwriters, if any.

                  (m) Prior to the effective date of the first Registration
Statement relating to the Registrable Notes, (i) provide the Trustee with
printed certificates for the Registrable Notes in a form eligible for deposit
with The Depository Trust Company and (ii) provide a CUSIP number for the
Registrable Notes.

                  (n) In connection with an underwritten offering of Registrable
Notes pursuant to a Shelf Registration, enter into an underwriting agreement as
is customary in underwritten offerings of debt securities similar to the Notes
and take all such other actions as are reasonably requested by the managing
underwriter or underwriters in order to expedite or facilitate the registration
or the disposition of such Registrable Notes and, in such connection, (i) make
such reasonable representations and warranties to the underwriters, with respect
to the business of the Issuers and their subsidiaries and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, as are customarily made by
issuers to underwriters in underwritten offerings of debt securities similar to
the Notes, and confirm the same in writing if and when requested; (ii) obtain
the opinion of counsel to the Issuers and updates thereof in form and substance
reasonably satisfactory to the managing underwriter or underwriters, addressed
to the underwriters covering the matters customarily covered in opinions
requested in underwritten offerings of debt securities similar to the Notes and
such other matters as may be reasonably requested by underwriters; (iii) obtain
"cold comfort" letters and updates thereof in form and substance reasonably
satisfactory to the managing underwriter or underwriters from the independent
certified public accountants
<PAGE>
                                      -21-

of the Issuers (and, if necessary, any other independent certified public
accountants of any subsidiary of any Issuer or of any business acquired by any
Issuer (including Muzak Limited Partnership, a Delaware limited partnership) for
which financial statements and financial data are, or are required to be,
included in the Registration Statement), addressed to each of the underwriters,
such letters to be in customary form and covering matters of the type
customarily covered in "cold comfort" letters in connection with underwritten
offerings of debt securities similar to the Notes and such other matters as
reasonably requested by the managing underwriter or underwriters; and (iv) if an
underwriting agreement is entered into, the same shall contain indemnification
provisions and procedures no less favorable than those set forth in Section 7
hereof (or such other provisions and procedures acceptable to Holders of a
majority in aggregate principal amount of Registrable Notes covered by such
Registration Statement and the managing underwriter or underwriters or agents)
with respect to all parties to be indemnified pursuant to said Section. The
above shall be done at each closing under such underwriting agreement, or as and
to the extent required thereunder.

                  (o) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, make available for inspection by any selling Holder of such
Registrable Notes being sold, and each Participating Broker-Dealer, any
underwriter participating in any such disposition of Registrable Notes, if any,
and any attorney, accountant or other agent retained by any such selling Holder,
each Participating Broker-Dealer, as the case may be, or underwriter
(collectively, the "Inspectors"), at the offices where normally kept, during
reasonable business hours, all financial and other records, pertinent corporate
documents and properties of each Issuer and its subsidiaries (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise any
applicable due diligence responsibilities, and cause the officers, directors and
employees of each Issuer and its subsidiaries to supply all information
reasonably requested by any such Inspector in connection with such Registration
Statement. Records which an Issuer determines, in good faith, to be confidential
and any
<PAGE>
                                      -22-

Records which it notifies the Inspectors are confidential shall not be disclosed
by the Inspectors unless (i) the disclosure of such Records is necessary to
avoid or correct a misstatement or omission in such Registration Statement, (ii)
the release of such Records is ordered pursuant to a subpoena or other order
from a court of competent jurisdiction or (iii) the information in such Records
has been made generally available to the public other than as a result of a
disclosure or failure to safeguard by such Inspector. Each selling Holder of
such Registrable Notes and each Participating Broker-Dealer will be required to
agree that information obtained by it as a result of such inspections shall be
deemed confidential and shall not be used by it as the basis for any market
transactions in the securities of any Issuer unless and until such is made
generally available to the public. Each Inspector, each selling Holder of such
Registrable Notes and each Participating Broker-Dealer will be required to
further agree that it will, upon learning that disclosure of such Records is
sought in a court of competent jurisdiction pursuant to clause (ii) of the
previous sentence or otherwise, give notice to the Issuers and allow the Issuers
to undertake appropriate action to obtain a protective order or otherwise
prevent disclosure of the Records deemed confidential at its expense.

                  (p) Provide an indenture trustee for the Registrable Notes or
the Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a), as the case may be, to be qualified
under the TIA not later than the effective date of the Exchange Offer or the
first Registration Statement relating to the Registrable Notes; and in
connection therewith, cooperate with the trustee under any such indenture and
the Holders of the Registrable Notes, to effect such changes to such indenture
as may be required for such indenture to be so qualified in accordance with the
terms of the TIA; and execute, and use its reasonable best efforts to cause such
trustee to execute, all documents as 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.

                  (q) Comply in all material respects with all applicable rules
and regulations of the Commission and make generally available to its
securityholders earnings statements satisfying the provisions of Section 11(a)
of the Securities Act and Rule 158 thereunder (or any similar rule promulgated
<PAGE>
                                      -23-

under the Securities Act) no later than 90 days after the end of any 12-month
period (i) commencing at the end of any fiscal quarter in which Registrable
Notes are sold to underwriters in a firm commitment or best efforts underwritten
offering and (ii) if not sold to underwriters in such an offering, commencing on
the first day of the first fiscal quarter of the Company after the effective
date of a Registration Statement, which statements shall cover said 12-month
periods.

                  (r) Upon consummation of the Exchange Offer or a Private
Exchange, obtain an opinion of counsel to the Issuers, in a form customary for
underwritten transactions, addressed to the Trustee for the benefit of all
Holders of Registrable Notes participating in the Exchange Offer or the Private
Exchange, as the case may be, that the Exchange Notes or the Private Exchange
Notes, as the case may be, the Guarantees and the related indenture constitute
legally valid and binding obligations of the Issuers, enforceable against the
Issuers in accordance with their respective terms.

                  (s) If the Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Notes by Holders to the Issuers
(or to such other Person as directed by the Company) in exchange for the
Exchange Notes or the Private Exchange Notes, as the case may be, the Issuers
shall mark, or caused to be marked, on such Registrable Notes that such
Registrable Notes are being canceled in exchange for the Exchange Notes or the
Private Exchange Notes, as the case may be; in no event shall such Registrable
Notes be marked as paid or otherwise satisfied.

                  (t) Cooperate with each seller of Registrable Notes covered by
any Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Notes and their respective counsel in connection
with any filings required to be made with the NASD.

                  (u) Use its reasonable best efforts to take all other steps
reasonably necessary to effect the registration of the Registrable Notes covered
by a Registration Statement contemplated hereby.

                  The Issuers may require each seller of Registrable Notes as to
which any registration is being effected to furnish to the Issuers such
information regarding such seller and the
<PAGE>
                                      -24-

distribution of such Registrable Notes as the Issuers may, from time to time,
reasonably request. The Issuers may exclude from such registration the
Registrable Notes of any seller who fails to furnish such information within a
reasonable time after receiving such request. Each seller as to which any Shelf
Registration Statement is being effected agrees 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 seller not materially
misleading.

                  Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by acquisition of such Registrable Notes or Exchange Notes
to be sold by such Participating Broker-Dealer, as the case may be, that, upon
receipt of any notice from the Issuers of the happening of any event of the kind
described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi), such Holder will
forthwith discontinue disposition of such Registrable Notes covered by such
Registration Statement or Prospectus or Exchange Notes to be sold by such Holder
or Participating Broker-Dealer, as the case may be, and, in each case,
dissemination of such Prospectus until such Holder's or Participating
Broker-Dealer's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto. In the event the
Issuers shall give any such notice, each of the Effectiveness Period and the
Applicable Period shall be extended by the number of days during such periods
from and including the date of the giving of such notice to and including the
date when each seller of Registrable Notes covered by such Registration
Statement or Exchange Notes to be sold by such Participating Broker-Dealer, as
the case may be, shall have received (x) the copies of the supplemented or
amended Prospectus contemplated by Section 5(k) or (y) the Advice.

6. Registration Expenses

                  All reasonable fees and expenses incident to the performance
of or compliance with this Agreement by the Issuers shall be borne by the
Issuers whether or not the Exchange Offer or a Shelf Registration is filed or
becomes effective, including, without limitation, (i) all registration and
filing fees (including, without limitation, (A) fees with respect to filings
required to be made with the NASD in connection with an

Broker-Dealer during the Applicable Period)), (ii) printing expenses, including,
without limitation, expenses of printing certificates for Registrable Notes or

aggregate principal amount of the Registrable Notes included in any Registration
Statement or by any Participating Broker-Dealer, as the case may be, (iii)
reasonable messenger, telephone and delivery expenses incurred in connection
with the Exchange Registration Statement and any Shelf Registration, (iv) fees
and disbursements of counsel for the Issuers and fees and disbursements of
special counsel for the Purchaser and the sellers of Registrable Notes, (v) fees
and disbursements of all independent certified public accountants referred to in
Section 5(n)(iii) (including, without limitation, the expenses of any special

Notes) and (xiii) the expenses relating to printing, word processing and
distributing all Registration Statements, underwriting agreements, securities

<PAGE>
                                      -26-

ments, indentures and any other documents necessary in order to comply with this
Agreement.

7. Indemnification

                  (a) Each of the Issuers jointly and severally agrees to
indemnify and hold harmless each Holder of Registrable Notes and each
Participating Broker-Dealer, the officers, directors, employees and agents of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "Participant"), from and against any and all losses,
claims, damages and liabilities (including, without limitation, the reasonable
legal fees and other reasonable expenses actually incurred in connection with
any suit, action or proceeding or any claim asserted) caused by, arising out of
or based upon any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement or Prospectus (as amended or
supplemented if the Issuers shall have furnished any amendments or supplements
thereto) or caused by, arising out of or based upon any 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, except insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Participant furnished to the Issuers in writing
by or on behalf of such Participant expressly for use therein; provided,
however, that the Issuers shall not be liable if such untrue statement or
omission or alleged untrue statement or omission was contained or made in any
preliminary prospectus and corrected in the Prospectus or any amendment or
supplement thereto and the Issuers shall have furnished the Prospectus or an
amendment or supplement thereto in compliance with Section 5 of this Agreement.

                  (b) Each Participant will be required to agree, severally and
not jointly, to indemnify and hold harmless each Issuer, its directors and
officers and each Person who controls each Issuer within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act to the same extent as
the foregoing indemnity from the Issuers to each Participant, but only with
reference to information relating to such Participant
<PAGE>
                                      -27-

furnished to the Issuers in writing by such Participant expressly for use in any
Registration Statement or Prospectus, any amendment or supplement thereto, or
any preliminary prospectus. The liability of any Participant under this
paragraph shall in no event exceed the proceeds received by such Participant
from sales of Registrable Notes or Exchange Notes giving rise to such
obligations.

                  (c) If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnity may be sought pursuant
to either of the two preceding paragraphs, such Person (the "Indemnified
Person") shall promptly notify the Person against whom such indemnity may be
sought (the "Indemnifying Person") in writing, and the Indemnifying Person, upon
request of the Indemnified Person, shall retain counsel reasonably satisfactory
to the Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such proceeding; provided, however, that the failure to so notify the
Indemnifying Person shall not relieve it of any obligation or liability which it
may have hereunder or otherwise except to the extent it has been materially
prejudiced by such failure. In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed in
writing to the contrary, (ii) the Indemnifying Person has failed within a
reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It is
understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed promptly upon demand. Any such separate firm for the Participants
and such control Persons of Participants shall be designated in writing by
Participants who
<PAGE>
                                      -28-

sold a majority in interest of Registrable Notes sold by all such Participants
and any such separate firm for each Issuer, its directors, officers and such
control Persons of each Issuer shall be designated in writing by the Company.
The Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there is a final non-appealable judgment for the plaintiff, the Indemnifying
Person agrees to indemnify any Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. No Indemnifying Person
shall, without the prior written consent (which consent shall not be
unreasonably withheld) of the Indemnified Person, effect any settlement of any
pending or threatened proceeding in respect of which any Indemnified Person is
or could have been a party and indemnity could have been sought hereunder by
such Indemnified Person, unless such settlement (A) includes an unconditional
release of such Indemnified Person, in form and substance satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of an Indemnified Person.

                  (d) If the indemnification provided for in the first and
second paragraphs of this Section 7 is unavailable to, or insufficient to hold
harmless, an Indemnified Person in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Person under such
paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in
order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions (or alleged statements or omissions) that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as well as any
other relevant equitable considerations. The relative fault of the parties 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 on the one hand
or by the Participants or such other Indemnified Person, as the case may be, on
the other, the parties' relative
<PAGE>
                                      -29-

intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission and any other equitable considerations appropriate
under the circumstances.

                  (e) The parties agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Participants were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any reasonable legal or other expenses actually incurred by such
Indemnified Person in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes, as the case may be, exceeds the amount of any damages that such
Participant has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

                  (f) The indemnity and contribution agreements contained in
this Section 7 will be in addition to any liability which the Indemnifying
Persons may otherwise have to the Indemnified Persons referred to above.

8. Rules 144 and 144A

                  Each of the Issuers covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the Commission thereunder in a timely manner
and, if at any time it is not required to file such reports, it will, upon the
request of any Holder of Registrable Notes, make publicly available other
information so long as necessary to permit sales pursuant to Rule 144 and Rule
144A under the Securities Act. Each of the Issuers further covenants, for so
long as any Registrable
<PAGE>
                                      -30-

Notes remain outstanding, to make available to any Holder or beneficial owner of
Registrable Notes in connection with any sale thereof and any prospective
purchaser of such Registrable Notes from such Holder or beneficial owner, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Registrable Notes pursuant to Rule 144A.

9. Underwritten Registrations

                  If any of the Registrable Notes covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will manage the offering will
be selected by the Holders of a majority in aggregate principal amount of such
Registrable Notes included in such offering and reasonably acceptable to the
Issuers.

                  No Holder of Registrable Notes may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Notes on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

10. Miscellaneous

                  (a) Remedies. In the event of a breach by any Issuer of any of
its obligations under this Agreement, each Holder of Registrable Notes and each
Participating Broker-Dealer holding Exchange Notes, in addition to being
entitled to exercise all rights provided herein, in the Indenture or, in the
case of the Purchaser, in the Purchase Agreement, or granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement. Each Issuer agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agrees that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

                  (b) No Inconsistent Agreements. None of the Issuers has
entered, as of the date hereof, and none of the Issuers
<PAGE>
                                      -31-

shall enter, after the date of this Agreement, into any agreement with respect
to any of its securities that is inconsistent with the rights granted to the
Holders of Registrable Notes in this Agreement or otherwise conflicts with the
provisions hereof. None of the Issuers has entered and none of the Issuers shall
enter into any agreement with respect to any of its securities which will grant
to any Person piggy-back rights with respect to a Registration Statement.

                  (c) Adjustments Affecting Registrable Notes. None of the
Issuers shall, directly or indirectly, take any action with respect to the
Registrable Notes as a class that would adversely affect the ability of the
Holders of Registrable Notes to include such Registrable Notes in a registration
undertaken pursuant to this Agreement.

                  (d) Amendments and Waivers. The provisions of this Agreement
may not be amended, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, otherwise than with the
prior written consent of (A) the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Notes and (B) in
circumstances that would adversely affect Participating Broker-Dealers, the
Participating Broker-Dealers holding not less than a majority in aggregate
principal amount of the Exchange Notes held by all Participating Broker-Dealers.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Notes whose securities are being tendered pursuant to the
Exchange Offer or sold pursuant to a Registration Statement and that does not
directly or indirectly affect, impair, limit or compromise the rights of other
Holders of Registrable Notes may be given by Holders of at least a majority in
aggregate principal amount of the Registrable Notes being tendered or being sold
by such Holders pursuant to such Registration Statement.

                  (e) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, next-day air courier or telecopier:

                  Copies of all such notices, demands or other communications
shall be concurrently delivered by the Person giving the same to the Trustee
under the Indenture at the address specified in such Indenture.

                  (f) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
hereto and the Holders; provided, however, that this Agreement shall not inure

and to the extent such successor or assign holds Registrable Notes.

                  (g) Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken

                  (h) Headings. The headings in this Agreement are for

                  (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND

<PAGE>
                                      -34-

                  (j) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

                  (k) Notes Held by any Issuer or Its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable Notes is
required hereunder, Registrable Notes held by any Issuer or its affiliates (as
such term is defined in Rule 405 under the Securities Act) shall not be counted
in determining whether such consent or approval was given by the Holders of such
required percentage.

                  (l) Third Party Beneficiaries. Holders of Registrable Notes
and Participating Broker-Dealers are intended third party beneficiaries of this
Agreement and this Agreement may be enforced by such Persons.

                  (m) Entire Agreement. This Agreement, together with the
Purchase Agreement and the Indenture, is intended by the parties as a final and
exclusive statement of the agreement and understanding of the parties hereto in
respect of the subject matter contained herein and therein and any and all prior
oral or written agreements, representations, or warranties, contracts,
understandings, correspondence, conversations and memoranda among the Purchaser
on the one hand and the Issuers on the other, or between or among any agents,
representatives, parents, subsidiaries, affiliates, predecessors in interest or

guaranteed) and (2) the subordination is for the benefit of and shall be
enforceable by all holders of Senior Indebtedness. Until the Senior Indebtedness

distribution on account of principal of, or premium or interest on, or any other

of Senior Indebtedness (PRO RATA to such holders on the basis of the respective
amounts of Senior Indebtedness held by such holders) or their representative as
their respective interests may appear to the extent necessary to pay all Senior
Indebtedness in full, in cash. In the event of the failure of the Subordinated
Payee to endorse or assign such payment or distribution, each holder of Senior
Indebtedness is hereby irrevocably authorized to endorse or assign the same.

1. Upon any Distribution of Assets of the Company or upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy,

similar proceeding, or upon any assignment for the benefit of creditors or any
other marshaling of the assets and liabilities of the Company, whether voluntary
or involuntary or otherwise (each, a "Proceeding"):
<PAGE>

(i) holders of Senior Indebtedness shall first be entitled to receive
indefeasible payment in full in cash of such Senior Indebtedness (whenever
arising and including interest after the commencement of any such Proceeding at
the rate specified in the Senior Indebtedness, whether or not a claim for such
interest would be allowed in such Proceeding) before the Subordinated Payee
shall be entitled to receive any payment on account of any Obligation with
respect to this Subordinated Note, whether as principal, interest or otherwise;
and

(i) any payment by, or on behalf of, or Distribution of Assets of, the Company
of any kind or character, whether in cash, property or securities, to which the
Subordinated Payee would be entitled except for the provisions of this Section
10 shall be paid or delivered by the Person making such payment or distribution
(whether the Company, a trustee in bankruptcy, a receiver, custodian or
liquidating trustee or other Person) directly to holders of Senior Indebtedness
as their interests may appear, until the indefeasible payment in full in cash of
all Senior Indebtedness.

1. The Company will not give, or permit to be given, and the Subordinated Payee
will not receive, accept or demand, (i) any security of any nature whatsoever
for any indebtedness evidenced by this Subordinated Note, whether principal or
interest, on any property or assets, whether now existing or hereafter acquired,
of the Company or any subsidiary thereof or (ii) any guarantee, of any nature
whatsoever, by the Company or any subsidiary thereof, of any indebtedness
evidenced by of this Subordinated Note, whether principal or interest.

1. The Subordinated Payee agrees not to file, or to join with any other
creditors of the Company or any Credit Party in filing, any petition commencing
any Proceeding. The Subordinated Payee further agrees, to the fullest extent
permitted under applicable law, that it will not cause the Company or any Credit
Party to file any petition commencing any Proceeding until all Senior
Indebtedness has been indefeasibly paid in full in cash.

1. To the extent any payment of or distribution in respect of Senior
Indebtedness (whether by or on behalf of the Company or any Credit Party, as
proceeds of security or enforcement of any right of setoff or otherwise) is
declared to be fraudulent or preferential, set aside or required to be paid to
any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or
similar law, then if such payment or distribution is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Senior Indebtedness or part thereof originally intended to
be satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred. To the extent the obligation to repay the Senior Indebtedness
is declared to be fraudulent, invalid or otherwise set aside under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then
the obligation so declared fraudulent, invalid or otherwise set aside (and all
other amounts that would come due with respect thereto had such obligation not
been so affected) shall be deemed to be
<PAGE>

reinstated and outstanding as Senior Indebtedness for all purposes hereof as if
such declaration, invalidity or setting aside had not occurred.

1. The holders of the Senior Indebtedness shall be entitled pro rata in
accordance with the priorities then existing among such holders to vote all
claims of the Subordinated Payee in respect of this Subordinated Note in
connection with a Proceeding. Notwithstanding the foregoing, in the event that
the holders of the Senior Indebtedness shall allow the Subordinated Payee to
retain the right to vote and otherwise act in a Proceeding (including, without
limitation, the right to vote to accept or reject any plan of partial or
complete liquidation, reorganization, arrangement, composition or extension),
the Subordinated Payee shall not vote with respect to any such plan or take any
other action in any way so as to contest (x) the validity of any liens or
security interests granted to, or for the benefit of, the holders of the Senior
Indebtedness, (y) the relative rights and duties of the holders of the Senior
Indebtedness established in the Credit Agreement with respect to such liens and
security interests or (z) the enforceability of the Credit Agreement or these
subordination provisions.

1. In connection with any Proceeding, the Subordinated Payee irrevocably
authorizes the holders of the Senior Indebtedness or any of them, to demand, sue
for, collect and receive all payments and distributions to the extent required
in this Section 10(a), to give acquittance therefor and to take such other
actions as such holders of the Senior Indebtedness may deem necessary or
advisable for the enforcement of these subordination provisions. The
Subordinated Payee further agrees duly and promptly to take such action as may
be requested at any time or from time to time by the holders of the Senior
Indebtedness, to file appropriate proofs of claim in respect of the Subordinated
Note and to execute and deliver such powers of attorney, assignments or proofs
of claim or other instruments as may be requested by the holders of the Senior
Indebtedness, all as may be necessary or advisable to enable such holders of the
Senior Indebtedness to enforce any and all claims upon or in respect of this
Subordinated Note and to receive any and all payments or distributions to the
extent required in this Section 10(a).
<PAGE>

A. WAIVERS AND CONSENTS.

1. The Subordinated Payee waives the right to compel that any collateral or any
other property of the Company or the property of any guarantor of any Senior
Indebtedness or any other Person be applied in any particular order to discharge
such Senior Indebtedness. The Subordinated Payee expressly waives the right to
require holders of Senior Indebtedness to proceed against the Company, any
collateral or any guarantor of any Senior Indebtedness or any other Person, or
to pursue any other remedy in any such holder's power which the Subordinated
Payee cannot pursue and which would lighten the Subordinated Payee's burden,
notwithstanding that the failure of any holder of Senior Indebtedness to do so
may thereby prejudice the Subordinated Payee. The Subordinated Payee agrees that
it shall not be discharged, exonerated or have its obligations hereunder to any
holder of Senior Indebtedness reduced by any such holder's delay in proceeding
against or enforcing any remedy against the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person; by any holder of
Senior Indebtedness releasing the Company, any collateral or any guarantor of
any Senior Indebtedness or any other Person from all or any part of such Senior
Indebtedness; or by the discharge of the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person by operation of law or
otherwise, with or without the intervention or omission of a holder of Senior
Indebtedness. Any holder's of Senior Indebtedness vote to accept or reject any
plan of reorganization relating to the Company, any collateral, or any guarantor
of such Senior Indebtedness or any other Person, or any holder's of Senior
Indebtedness receipt on account of all or part of any Senior Indebtedness of any
cash, property or securities distributed in any Proceeding, shall not discharge,
exonerate or reduce the obligations of the Subordinated Payee hereunder to any
holder of Senior Indebtedness.

2. The rights under these subordination provisions of the holders of any Senior
Indebtedness as against the Subordinated Payee shall remain in full force and

election of remedies by any holder of Senior Indebtedness, even though that

against the Company or any guarantor of any Senior Indebtedness or any other

have by reason of protection afforded to the Company or any guarantor of any

continued, and such Senior Indebtedness, or the liability of the Company or any
of its subsidiaries or any other guarantor or any other party upon or for any
part thereof, or any collateral or guarantee therefor or right of offset with
respect thereto, may, from time to time, in whole or in part, be renewed,
extended, modified, accelerated, compromised, waived, surrendered or released by
the holders of such Senior Indebtedness, in each case without notice to or
further assent by the Subordinated Payee and without impairing, abridging,
releasing or affecting the subordination provided for herein.

extension or accrual of any Senior Indebtedness and notice of or proof of
reliance by any holder of Senior Indebtedness upon the provisions of this

created, contracted or incurred and the consent given to create the obligations
of the Company in respect of this Subordinated Note in reliance upon the
provisions of this Section 10, and all dealings between the Company and any
holder of Senior Indebtedness shall be deemed to have been consummated in

assigns, hereby waives any and all now existing or hereafter arising rights it
may have to require any holder of Senior Indebtedness to marshal assets for the
benefit of the Subordinated Payee, or to otherwise direct or receive notice of
the timing, order or manner of any sale, collection or other enforcement of any
collateral. The holders of Senior Indebtedness are under no duty or obligation,
and the Subordinated Payee hereby waives any right it may have to compel any
holder of Senior Indebtedness, to pursue any guarantor or other Person who may
be liable for such Senior Indebtedness, or to enforce any lien or security
interest in any collateral.

1. The Subordinated Payee hereby waives and releases all rights which a
guarantor or surety with respect to any Senior Indebtedness could exercise.

1. The Subordinated Payee hereby waives any duty on the part of any holder of

Payee, the obligation of the Company which is absolute and unconditional, to pay
principal of, premium, if any, and interest on this Subordinated Note in
accordance with its terms; or (ii) affect the relative rights of the
Subordinated Payee and creditors of the Company other than their rights in
relation to holders of Senior Indebtedness.

A. SUBROGATION. The Subordinated Payee shall not have any subrogation or other
rights as the holder of Senior Indebtedness, and the Subordinated Payee hereby
waives all such rights of subrogation and all rights of reimbursement or
indemnity whatsoever and all rights of recourse to any security for any Senior
Indebtedness, until such time as all the Senior Indebtedness shall be
indefeasibly paid in full in cash and all of the Obligations of the Credit
Parties under the Senior Indebtedness shall have been duly performed. From and
after the time at which all Senior Indebtedness has been indefeasibly paid in
full in cash, the rights of the Subordinated Payee shall be subrogated to all
rights of any holders of Senior Indebtedness to receive any further payments or
distributions applicable to the Senior Indebtedness until the subordinated
amounts due pursuant to the Subordinated Note shall have been indefeasibly paid
in full in cash, and for the purposes of such subrogation, no payment or
distribution received by the holders of Senior Indebtedness of cash, securities
or other property to which the Subordinated Payee would have been entitled
except for these subordination provisions shall, as between the Company and its
creditors other than the holders of Senior Indebtedness, on the one hand, and
the Subordinated Payee, on the other, be deemed to be a payment or distribution
by the Company to or on account of the Senior Indebtedness.

A. AUTHORIZATION TO EFFECT SUBORDINATION. The Subordinated Payee by its
acceptance of this Subordinated Note authorizes and directs the holders of
Senior Indebtedness to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Section (including, without
limitation, to demand, sue for, collect and receive all payments and
distributions), and appoints the holders of Senior Indebtedness to act as their
attorney-in-fact for any and all such purposes, including, upon the occurrence
of any Proceeding as set forth in Section 10(a).

I. TRANSFERABILITY AND ASSIGNMENT. A Subordinated Payee may not transfer, sell,
pledge, convey, assign or otherwise dispose of ("Transfer") this Subordinated
Note to any other Person without (a) the prior written consent of the Company's
Board of Directors, (b) first delivering to the Company (i) an opinion of
counsel reasonably acceptable in form and substance to the Company (which
counsel must be reasonably acceptable to the Company) that registration under
the Securities Act, or any state or other securities law is not required in
connection with such Transfer and (ii) a written joinder to this Subordinated
Note by the proposed transferee pursuant to which such proposed transferee shall
agree to be bound by the provisions of this Subordinated Note, including Section
10 and (c) so long as any Senior Indebtedness remains outstanding, the prior
written consent of the holders of Senior Indebtedness or
<PAGE>

any representative of such holders authorized to give a consent to such joinder
and such transferee. Any transferee executing and delivering such a joinder and
thereafter acquiring this Subordinated Note in accordance with the preceding
sentence shall be referred to herein as a "Permitted Transferee". Any Transfer
or attempted Transfer of this Subordinated Note in violation of any provision of
this Subordinated Note shall be null and void, and the Company shall not record
such Transfer on its books or treat any purported transferee of this
Subordinated Note as the owner of this Subordinated Note for any purpose.

I. COUNTERPARTS. This Subordinated Note may be executed in separate counterparts
each of which shall be an original and all of which taken together shall
constitute one and the same agreement.

I. USURY LAWS. It is the intention of the Company and the Subordinated Payee to
conform strictly to all applicable usury laws now or hereafter in force, and any
interest payable under this Subordinated Note shall be subject to reduction to
the amount not in excess of the maximum legal amount allowed under the
applicable usury laws as now or hereafter construed by the courts having
jurisdiction over such matters. If the maturity of this Subordinated Note is
accelerated by reason of an election by the holder hereof resulting from an
Event of Default, voluntary prepayment by the Company or otherwise, then earned
interest may never include more than the maximum amount permitted by law,
computed from the date hereof until payment, and any interest in excess of the
maximum amount permitted by law shall be canceled automatically and, if
theretofore paid, shall at the option of the Subordinated Payee either be
rebated to the Company or credited on the principal amount of this Subordinated
Note, or if this Subordinated Note has been paid, then the excess shall be
rebated to the Company. The aggregate of all interest (whether designated as
interest, service charges, points or otherwise) contracted for, chargeable, or
receivable under this Subordinated Note shall under no circumstances exceed the
maximum legal rate upon the unpaid principal balance of this Subordinated Note
remaining unpaid from time to time. If such interest does exceed the maximum
legal rate, it shall be deemed a mistake and such excess shall be canceled
automatically and, if theretofore paid, rebated to the Company or credited on
the principal amount of this Subordinated Note, or if this Subordinated Note has
been repaid, then such excess shall be rebated to the Company.

I. NO STRICT CONSTRUCTION. The parties hereto have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties hereto, and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

I. AMENDMENTS; WAIVERS. So long as any Senior Indebtedness remains outstanding,
no amendment or modification to or waiver of any provisions of, or the
definitions of any terms appearing in, Section 10, or to or of any other
provision of this Subordinated Note may be made that affects the rights of any
<PAGE>

holder of Senior Indebtedness then outstanding unless the holders of such Senior
Indebtedness, or any representative of such holders authorized to give a
consent, consent to such amendment, modification or waiver; provided, however,
that this Subordinated Note may be amended to increase the Original Principal
Amount by an additional amount not to exceed $5,000,000 without the consent of
the holders of Senior Indebtedness.

guarantee, of any nature whatsoever, by the Company or any other Credit Party,
of any Subordinated Obligations.

                  The Subordinated Payee acknowledges and agrees that the
subordination provisions herein are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness, whether such Senior
Indebtedness was created or acquired before or after the issuance of this
Subordinated Note, to acquire and continue to hold, or to continue to hold such
Senior Indebtedness.

                  To the extent that any payment of or distribution in respect
of Senior Indebtedness (whether by or on behalf of the Company , as proceeds of
security or enforcement of any right of setoff or otherwise) is declared to be
fraudulent or preferential, set aside or required to be paid to any receiver,
trustee in bankruptcy, liquidating trustee, agent or other similar Person under
any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then if such payment or distribution is recovered by, or paid over to, such
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person, the Senior Indebtedness or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred. To the extent that the obligation to repay the Senior
Indebtedness is declared to be fraudulent, invalid or otherwise set aside under
any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then the obligation so declared fraudulent, invalid or otherwise set aside (and
all other amounts that would come due with respect thereto had such obligation
not been so affected) shall be deemed to be reinstated and outstanding as Senior
Indebtedness for all purposes hereof as if such declaration, invalidity or
setting aside had not occurred.

A. Distributions and Liquidation, Dissolution, Bankruptcy. In the event of (i)
any distribution of assets of the Company, (ii) any insolvency, or bankruptcy,
case or proceeding, or any receivership, liquidation, reorganization,
arrangement, adjustment, action for the relief of debtors, or other similar case
or proceeding in connection therewith, relative to the Company, its debts, its
operations or to its creditors, as such, or to its assets, or (iii) any
liquidation, dissolution or other winding-up of the Company and whether or not
involving insolvency or bankruptcy, or (iv) any assignment for the benefit of
creditors or any other marshaling of assets or liabilities of the Company, in
each case whether voluntary or involuntary, including, without limitation, the
filing of any petition or the taking of any action to commence any of the
foregoing under any law, foreign or domestic, federal or state (clauses (ii)
through (iv) are referred to as a "Bankruptcy Proceeding"), then and in any such
event:

                  (i) The Senior Agent and the holders of Senior Indebtedness
         shall be entitled to receive indefeasible payment and satisfaction in
         full in cash of all amounts due on or in respect of all Senior
         Indebtedness (including, but not limited to, interest accruing at the
         legal rate on or after the filing of any Bankruptcy Proceeding, and any
         additional interest that would have accrued thereon but for
<PAGE>

         the commencement of such proceeding, whether or not a claim for such is
         allowed in such proceeding), before the Subordinated Payee is entitled
         to receive or retain any payment or distribution of any kind or
         character on account of this Subordinated Note or any Subordinated
         Obligations on this Subordinated Note;

                  (ii) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities, by
         set-off or otherwise, to which the Subordinated Payee would be entitled
         but for the provisions of this Section 10 shall be paid by the Company,
         a liquidating trustee or agent or other Person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the Senior Agent or the
         holders of Senior Indebtedness, ratably according to the aggregate
         amounts remaining unpaid on account of the Senior Indebtedness held or
         represented by each to the extent necessary to make indefeasible
         payment and satisfaction in full in cash of all Senior Indebtedness
         remaining unpaid, after giving effect to any concurrent payment or
         distribution to the Senior Agent or the holders of such Senior
         Indebtedness; and

                  (iii) in the event that, notwithstanding the foregoing
         provisions of this Section 10(b), the Subordinated Payee shall have
         received any payment or distribution of assets of the Company of any
         kind or character, whether in cash, or property or securities,
         including, without limitation, by way of set-off or otherwise, in
         respect of principal of, premium, if any, interest or any Subordinated
         Obligations on this Subordinated Note before all Senior Indebtedness is
         indefeasibly paid in full in cash, then and in such event payment or
         distribution shall be held in trust for the benefit of and shall be
         paid over or delivered forthwith to the trustee in bankruptcy,
         receiver, liquidating trustee, custodian, assignee, agent or other
         Person making payment or distribution of assets of the Company for
         application to the payment of all Senior Indebtedness remaining unpaid,
         to the extent necessary to indefeasibly pay and satisfy all Senior
         Indebtedness in full in cash, after giving effect to any concurrent
         payment or distribution to or for the holders of the Senior
         Indebtedness.
<PAGE>

A. No Payments with Respect to Subordinated Obligations.

1. Unless Section 10(b) shall be applicable, no payment or distribution of any
kind or character (including, without limitation, cash, property and any payment
or distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of this
Subordinated Note) may be made by or on behalf of the Company or accepted by the
Subordinated Payee, including, without limitation, by way of set-off or
otherwise, for or on account of this Subordinated Note or of any Subordinated
Obligations under this Subordinated Note, or for or on account of the purchase,
redemption or other acquisition of this Subordinated Note, and the Subordinated
Payee shall not take or receive from the Company, directly or indirectly in any
manner, payment in respect of all or any portion of this Subordinated Note or of
any Subordinated Obligations under this Subordinated Note, or for or on account
of the purchase, redemption or other acquisition of this Subordinated Note until
the indefeasible payment and satisfaction in full in cash of all Senior
Indebtedness.

A. When Distribution Must Be Paid Over. In the event that notwithstanding these
provisions, the Subordinated Payee receives any payment or distribution of
assets of the Company of any kind, whether in cash, property or securities,
including, without limitation, by way of set-off or otherwise, in respect of
this Subordinated Note or any Subordinated Obligations under this Subordinated
Note, that the Subordinated Payee is not entitled to receive or retain under the
provisions of this Subordinated Note, then such payment or distribution shall be
held by the Subordinated Payee in trust for the benefit of the Senior Agent and
the Subordinated Payees of Senior Indebtedness, (segregated from other assets
held by the Subordinated Payee) and shall be immediately paid over or delivered
to the Senior Agent in the form received (with any necessary endorsement) to the
extent necessary to make indefeasible payment and satisfaction in full in cash
of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.
In the event of the failure of the Subordinated Payee to endorse or assign any
such payment or distribution, the Senior Agent is hereby irrevocably authorized
to endorse or assign the same.

A. Exercise of Remedies. Until the indefeasible payment and satisfaction in full
in cash of all Senior Indebtedness, the Subordinated Payee (solely in its
capacity as a holder of this Subordinated Note) shall not exercise any rights or
remedies with respect to this Subordinated Note, including, without limitation,
any administrative, legal, equitable or other action (i) to demand or sue for
collection of amounts payable hereunder, (ii) to accelerate the principal of
this Subordinated Note, (iii) to commence or join with any other creditor in
commencing any proceeding in connection with or premised on the occurrence of a
Bankruptcy Proceeding, or (iv) to take, obtain or hold (or to permit anyone
acting on its behalf to take, obtain or hold) any assets of the Company.
<PAGE>

A. Rights. The provisions of this Section 10 are for the benefit of, and shall
be enforceable directly by, the Senior Agent and the holders of Senior
Indebtedness (and their successors and assigns), the Senior Agent and each
holder of Senior Indebtedness is made an obligee hereunder, and the Senior Agent
and each holder of Senior Indebtedness, whether now outstanding or hereafter
created, incurred, assumed, or guaranteed shall be deemed conclusively to have
acquired or to continue to hold such Senior Indebtedness in reliance upon the
covenants and provisions contained in this Subordinated Note. The Subordinated
Payee acknowledges and agrees that any breach of the provisions of this Section
10 will cause irreparable harm of which the payment of monetary damages may be
inadequate. For this reason, the Subordinated Payee agrees that, in addition to
any remedies at law or in equity to which the Senior Agent or a Subordinated
Payee of the Senior Indebtedness may be entitled, the Senior Agent or a holder
of the Senior Indebtedness will be entitled to an injunction or other equitable
relief to prevent breaches of the provisions of this Section 10 and to compel
specific performance of such provisions.

                  The provisions of this Section 10 are and are intended solely
for the purpose of defining the relative rights of the Subordinated Payee on the
one hand and the Senior Agent and the holders of Senior Indebtedness on the
other hand. Nothing contained in this Section 10 or elsewhere in this
Subordinated Note is intended to or shall impair, as among the Company its
creditors other than the holders of Senior Indebtedness and the Subordinated
Payee, the obligation of the Company, which is absolute and unconditional, to
pay to the Subordinated Payee the principal of, premium, if any, and interest on
this Subordinated Note as and when the same shall become due and payable in
accordance with its terms.

A. Acceleration of Payment of Subordinated Note. If this Subordinated Note is
declared due and payable prior to the Maturity Date, no direct or indirect
payment that is due solely by reason of such declaration shall be made, nor
shall application be made of any distribution of assets of the Company to the
payment, purchase or other acquisition or retirement of this Subordinated Note,
unless, in either case, all Senior Indebtedness shall have been previously
indefeasibly paid and satisfied in full in cash.

A. Voting Rights; Authorization to Effect Subordination. The Senior Agent shall
be entitled to file and prove all claims and to exercise any right to vote of
the Subordinated Payee in respect of this Subordinated Note in connection with a
Bankruptcy Proceeding. Notwithstanding the foregoing, in the event that the
Senior Agent shall allow the Subordinated Payee to retain the right to vote and
otherwise act in a Bankruptcy Proceeding (including, without limitation, the
right to vote to accept or reject any plan of partial or complete liquidation,
reorganization, arrangement, composition or extension), the Subordinated Payee
shall not vote with respect to any such plan or take any other action in any way
so as to contest (x) the validity of any liens or security interests granted to
the Senior Agent, (y) the relative rights and duties of the Senior Agent or the
holders of the Senior Indebtedness established in the Senior Credit Agreement
with respect to such liens and security interests or (z) the enforceability of
the Senior Credit Agreement or these subordination provisions.
<PAGE>

                  The Subordinated Payee hereby irrevocably authorizes , directs
and empowers the Senior Agent, and hereby appoints the Senior Agent to act as
its attorney-in-fact, for any and all of the following purposes, (i) to demand,
sue for, collect and receive all payments and distributions under the terms of
this Subordinated Note, (ii) to file and prove all claims and to exercise any
right to vote in any Bankruptcy Proceeding as set forth above, and (iii) to take
any and all other actions in the name of the Subordinated Payee (solely in its
capacity as a holder of this Subordinated Note), as the Senior Agent determines
in its sole discretion to be necessary or appropriate for the enforcement of the
subordination provisions in this Section 10. The Subordinated Payee further
agrees duly and promptly to take such action as may be requested at any time or
from time to time by the Senior Agent, including, without limitation, executing
and delivering any additional powers of attorney, assignments or proofs of
claims or other instruments and supplying any information and documents, to
enable the Senior Agent to take any of the foregoing actions.

                  Each right, power and remedy of the Senior Agent provided for
in this Subordinated Note or the Senior Credit Agreement, whether now existing
or hereafter available at law or in equity or by statute or otherwise, shall be
cumulative and concurrent and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by the Senior Agent
of any one or more of such rights, powers or remedies shall not preclude the
simultaneous or later exercise of all other such rights, powers or remedies, and
no course of dealing or failure or delay on the part of any party hereto in
exercising any such right, power, or remedy shall operate as a waiver thereof or
otherwise prejudice its rights, powers or remedies.

A. Subrogation. Upon the indefeasible payment and satisfaction in full in cash
of all Senior Indebtedness, the Subordinated Payee shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of, premium, if any, and interest on this
Subordinated Note shall be paid in full. For purposes of such subrogation, no
payments or distributions to the holders of Senior Indebtedness of any cash,
property or securities to which the Subordinated Payee would be entitled except
for the provisions of this Section 10, and no payments over pursuant to the
provisions of this Section 10 to the Senior Agent or the holders of Senior
Indebtedness by the Subordinated Payee shall, as among the Company, its
creditors other than the Senior Agent or the holders of Senior Indebtedness, and
the Subordinated Payee be deemed to be a payment or distribution by the Company
to or on account of the Senior Indebtedness.

                  If any payment or distribution to which the Subordinated Payee
would otherwise have been entitled but for the provisions of this Section 10
shall have been applied, pursuant to the provisions of this Section 10, to the
payment of all amounts payable under the Senior Indebtedness, then and in such
case the Subordinated Payee shall be entitled to receive from the Senior Agent
or the holders of such Senior Indebtedness at the time outstanding any payments
or distributions received by such
<PAGE>

holders of such Senior Indebtedness in excess of the amount sufficient to
indefeasibly pay and satisfy all amounts payable under or in respect of such
Senior Indebtedness in full in cash.

A. Waivers and Consents. The Subordinated Payee waives the right to compel that
any collateral or any other property of the Company or the property of any
guarantor of any Senior Indebtedness or any other Person to be applied in any
particular order to discharge such Senior Indebtedness. The Subordinated Payee
expressly waives the right to require the Senior Agent or the holders of Senior
Indebtedness to proceed against the Company, any collateral or any guarantor of
any Senior Indebtedness or any other Person, or to pursue any other remedy in
the power of the Senior Agent or any such holder which the Subordinated Payee
cannot pursue and which would lighten the Subordinated Payee's burden,
notwithstanding that the failure of any holder of Senior Indebtedness to do so
may thereby prejudice the Subordinated Payee. The Subordinated Payee agrees that
it shall not be discharged, exonerated or have its obligations hereunder to any
holder of Senior Indebtedness reduced by (i) holder's delay in proceeding
against or enforcing any remedy against the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person by the Senior Agent or
any holder of Senior Indebtedness; (ii) the Senior Agent or any holder of Senior
Indebtedness releasing the Company, any collateral or any guarantor of any
Senior Indebtedness or any other Person from all or any part of such Senior
Indebtedness; or (iii) the discharge of the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person by operation of law or
otherwise, with or without the intervention or omission of the Senior Agent or
any holder of Senior Indebtedness. Any vote by the Senior Agent or any holder of
Senior Indebtedness to accept or reject any plan of reorganization relating to
the Company, any collateral or any guarantor of such Senior Indebtedness or any
other Person, or any receipt by the Senior Agent or any holder of Senior
Indebtedness receipt on account of all or part of any Senior Indebtedness of any
cash, property or securities distributed in any Bankruptcy Proceeding, shall not
discharge, exonerate or reduce the obligations of the Subordinated Payee
hereunder to the Senior Agent and the holders of Senior Indebtedness.

                  No right of the Senior Agent or any present or future holder
of any Senior Indebtedness to enforce the provisions herein shall at any time in
any way be prejudiced or impaired or affected by (i) any act or failure to act
on the part of the Company or by any act or failure to act by the Senior Agent
or any such holder, (ii) any non-compliance by the Company with the terms,
provisions and covenants of this Subordinated Note or the Senior Credit
Agreement, or (iii) any merger or consolidation of the Company or any of its
subsidiaries into or with any other Person, or any sale, lease or transfer of
any or all of the assets of the Company or any of its subsidiaries to any other
Person, regardless in any case of any knowledge thereof of the Senior Agent or
any such holder may have or be otherwise charged with.

                  Without limiting the generality of the foregoing, the Senior
Agent and the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to or knowledge of the Subordinated
Payee, without incurring
<PAGE>

responsibility to the Subordinated Payee and without impairing or releasing the
provisions herein or the obligations hereunder of the Subordinated Payee to the
Senior Agent and the holders of Senior Indebtedness , do any one or more of the
following: (i) change the manner, place or terms of payment or extend the time
of payment of, or renew, alter, compromise or waive any Senior Indebtedness or
otherwise amend, modify or supplement in any manner any Senior Indebtedness or
any instrument evidencing the same or any agreement under which any Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing any Senior Indebtedness;
(iii) release any Person liable in any manner for the collection or payment of
any Senior Indebtedness; (iv) exercise or refrain from exercising any rights
against the Company or any other Person; and (v) fail to perfect a security
interest in any collateral for the payment of the Senior Indebtedness.

                  The Subordinated Payee waives all rights and defenses arising
out of an election of remedies by the Senior Agent or any holder of Senior
Indebtedness, even though that election of remedies, including, without
limitation, any nonjudicial foreclosure with respect to collateral for such
Senior Indebtedness, has impaired the value of the Subordinated Payee's rights
of subrogation, reimbursement or contribution against the Company, any guarantor
of any Senior Indebtedness or any other Person. The Subordinated Payee expressly
waives any rights or defenses it may have by reason of protection afforded to
the Company or any guarantor of any Senior Indebtedness or any other Person with
respect to such Senior Indebtedness pursuant to any anti-deficiency laws or
other laws of similar import which limit or discharge the principal debtor's
indebtedness upon judicial or nonjudicial foreclosure of real property or
personal property collateral for any Senior Indebtedness.

                  The Subordinated Payee agrees that, without the necessity of
any reservation of rights against it, and without notice to or further assent by
it, any demand for payment of any Senior Indebtedness made by the Senior Agent
or any holder of Senior Indebtedness may be rescinded in whole or in part by the
Senior Agent or any such holder, and any Senior Indebtedness may be continued,
and such Senior Indebtedness, or the liability of the Company or any of its
subsidiaries or any other guarantor or any other Person upon or for any part
thereof, or any collateral or guarantee therefor or right of offset with respect
thereto, may, from time to time, in whole or in part, be renewed, extended,
modified, accelerated, compromised, waived, surrendered or released by the
Senior Agent or any holder of such Senior Indebtedness, in each case without
notice to or further assent by the Subordinated Payee and without impairing,
abridging, releasing or affecting the subordination provided for herein.

                  The Subordinated Payee waives any and all notice of the
creation, renewal, extension or accrual of any Senior Indebtedness and notice of
or proof of reliance by the Senior Agent or any holder of Senior Indebtedness
upon the provisions of this Section 10. The Subordinated Payee waives
presentment, protest and demand for payment.
<PAGE>

                  To the maximum extent permitted by law, the Subordinated Payee
waives any claim it might have against the Senior Agent or any holder of Senior
Indebtedness with respect to, or arising out of, any action or failure to act or
any requirement of diligence on the part of the Senior Agent or any such holder
of Senior Indebtedness or any requirement on the part of the Senior Agent or any
such holder of Senior Indebtedness to mitigate damages resulting from any
default under such Senior Indebtedness, any error of judgment, negligence or
mistake or oversight whatsoever on the part of the Senior Agent or any such
holder of Senior Indebtedness or its respective directors, officers, employees
or agents with respect to any exercise of rights or remedies under the
agreements governing or relating to such Senior Indebtedness.

                  The Subordinated Payee, for itself and on behalf of its
successors and assigns, hereby waives any and all now existing or hereafter
arising rights it may have to require the Senior Agent or any holder of Senior
Indebtedness to marshal assets for the benefit of the Subordinated Payee, or to
otherwise direct or receive notice of the timing, order or manner of any sale,
collection or other enforcement of any collateral. Neither the Senior Agent nor
any holder of Senior Indebtedness is under any duty or obligation, and the
Subordinated Payee hereby waives any right it may have to compel the Senior
Agent or any holder of Senior Indebtedness, to pursue any guarantor or other
Person who may be liable for such Senior Indebtedness, or to enforce any lien or
security interest in any collateral.

                  The Subordinated Payee hereby waives and releases all rights
which a guarantor or surety with respect to any Senior Indebtedness could
exercise.

                  The Subordinated Payee hereby waives any duty on the part of
the Senior Agent or any holder of Senior Indebtedness to disclose to it any fact
known or hereafter known by it relating to the operation or financial condition
of the Company or any guarantor of such Senior Indebtedness or their respective
businesses or assets.

                  The Subordinated Payee unconditionally waives (i) notice of
any of the matters referred to in this Section 10, (ii) to the extent permitted
by law, all notices which may be required, whether by statute, rule of law or
otherwise, to preserve intact any rights of the Senior Agent or any holder of
any Senior Indebtedness against the Company, including, without limitation, any
demand, presentment, protest and default, proof of notice of nonpayment under
any Senior Indebtedness and notice of any failure on the part of the Company or
any other Credit Party to perform and comply with any covenant, agreement, term
or condition of the Senior Indebtedness, (iii) any right to the enforcement,
assertion or exercise by the Senior Agent or any holder of any Senior
Indebtedness of any right, power, privilege or remedy conferred in such Senior
Indebtedness or otherwise, and (iv) any notice of any sale, transfer or other
disposition of any Senior Indebtedness by any holder thereof.

A. Subordination to the Sub Debt Indebtedness. The Company covenants and agrees,
and the Subordination Payee by accepting this Subordinated Note covenants and
agrees, that so long as any Sub Debt Default or Sub Debt Event of Default
<PAGE>

shall have occurred and be continuing, no payment of principal of (and premium,
if any) or interest on, or any other payment obligations with respect to, this
Subordinated Note or any judgment with respect hereto shall be made by or on
behalf of the Company or any other Credit Party.

A. Conversion of this Subordinated Note. Notwithstanding anything contained
herein to the contrary, nothing contained in this Section 10 shall prevent any
conversion of this Subordinated Note in accordance with the provisions of
Section 16 hereof.

I. TRANSFERABILITY AND ASSIGNMENT. A Subordinated Payee may not transfer, sell,
pledge, convey, assign or otherwise dispose of ("Transfer") this Subordinated
Note to any other Person without (a) the prior written consent of the Company's
Board of Directors, (b) first delivering to the Company (i) an opinion of
counsel reasonably acceptable in form and substance to the Company (which
counsel must be reasonably acceptable to the Company) that registration under
the Securities Act, or any state or other securities law is not required in
connection with such Transfer and (ii) a written joinder to this Subordinated
Note by the proposed transferee pursuant to which such proposed transferee shall
agree to be bound by the provisions of this Subordinated Note, including Section
10 and (c) so long as any Senior Indebtedness remains outstanding, the prior
written consent of the holders of Senior Indebtedness or any representative of
such holders authorized to give a consent to such joinder and such transferee.
Any transferee executing and delivering such a joinder and thereafter acquiring
this Subordinated Note in accordance with the preceding sentence shall be
referred to herein as a "Permitted Transferee". Any Transfer or attempted
Transfer of this Subordinated Note in violation of any provision of this
Subordinated Note shall be null and void, and the Company shall not record such
Transfer on its books or treat any purported transferee of this Subordinated
Note as the owner of this Subordinated Note for any purpose.

I. COUNTERPARTS. This Subordinated Note may be executed in separate counterparts
each of which shall be an original and all of which taken together shall
constitute one and the same agreement.

I. USURY LAWS. It is the intention of the Company and the Subordinated Payee to
conform strictly to all applicable usury laws now or hereafter in force, and any
interest payable under this Subordinated Note shall be subject to reduction to
the amount not in excess of the maximum legal amount allowed under the
applicable usury laws as now or hereafter construed by the courts having
jurisdiction over such matters. If the maturity of this Subordinated Note is
accelerated by reason of an election by the holder hereof resulting from an
Event of Default, voluntary prepayment by the Company or otherwise, then earned
interest may never include more than the maximum amount permitted by law,
computed from the date hereof until payment, and any interest in excess of the
maximum amount permitted by law shall be canceled automatically and, if
theretofore paid, shall at the option of the Subordinated Payee either be
rebated to the Company or credited on the principal amount of this
<PAGE>

Subordinated Note, or if this Subordinated Note has been paid, then the excess
shall be rebated to the Company. The aggregate of all interest (whether
designated as interest, service charges, points or otherwise) contracted for,
chargeable, or receivable under this Subordinated Note shall under no
circumstances exceed the maximum legal rate upon the unpaid principal balance of
this Subordinated Note remaining unpaid from time to time. If such interest does
exceed the maximum legal rate, it shall be deemed a mistake and such excess
shall be canceled automatically and, if theretofore paid, rebated to the Company
or credited on the principal amount of this Subordinated Note, or if this
Subordinated Note has been repaid, then such excess shall be rebated to the
Company.

I. NO STRICT CONSTRUCTION. The parties hereto have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties hereto, and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

I. AMENDMENTS; WAIVERS. So long as any Senior Indebtedness remains outstanding,
no amendment or modification to or waiver of any provisions of, or the
definitions of any terms appearing in, Section 10, or to or of any other
provision of this Subordinated Note may be made that affects the rights of any
holder of Senior Indebtedness then outstanding unless the holders of such Senior
Indebtedness, or any representative of such holders authorized to give a
consent, consent to such amendment, modification or waiver.

I. CONVERSION.

A. Conversion Procedure.

1. Voluntary Conversion; Automatic Conversion. At any time after the date hereof
and prior to the payment of this Subordinated Note in full, the then
Subordinated Payee may convert this Subordinated Note into a number of Class A
Units determined by dividing (x) the then Convertible Amount (as herein defined)
by (y) $1,000 (the "Conversion Price"). Notwithstanding anything contained
herein to the contrary, if as of May 8, 2001, this Subordinated Note has not
been paid in full, then this Subordinated Note shall automatically be converted
into a number of Class A Units in accordance with the formula contained in the
first sentence of this Section 16(a)(i). If the Subordinated Payee is not a
Member (as such term is defined in the LLC Agreement) at the time of a
conversion of this Subordinated Note, then, at the time of such conversion of
this Subordinated Note, such Subordinated Payee agrees to deliver to the
Secretary of Holdings an executed joinder to the LLC Agreement and any other
documentation necessary in accordance with the requirements of the LLC Agreement
or any of the Related Agreements (as such term is defined in the LLC Agreement).
For purposes of this Subordinated Note, the "Convertible Amount" at any time
shall equal (x) the then outstanding principal amount of this Subordinated Note
plus (y) the interest which has
<PAGE>

then accrued in accordance with the provisions contained herein and which is
then unpaid, in each case, at such time.

1. Effect of Conversion. A conversion of this Subordinated Note will be deemed
to have been effected as of the close of business on the date on which this
Subordinated Note has been surrendered for conversion by the then Subordinated
Payee to the Secretary of Holdings; provided, that in the event of an automatic
conversion of this Subordinated Note, such automatic conversion will be deemed
to have been effected as of the close of business on the date of such automatic
conversion. At such time as such conversion has been effected, the rights of the
then Subordinated Payee (as well as any and all prior Subordinated Payees and
any other former or current holder of this Subordinated Note) under this
Subordinated Note will cease, the Company shall thereafter have no obligation to
make any principal, interest or other payments under this Subordinated Note and
such Subordinated Payee shall be deemed to be the record holder of the
applicable Class A Units which this Subordinated Note shall have then been
converted into. If this Subordinated Note is converted pursuant to this Section
16, no principal amount of, accrued interest on or any other amount pursuant to
this Subordinated Note will be payable at any time as of or after such
conversion.

A. Subdivision or Combination of Class A Units. If Holdings at any time
subdivides (by any unit split, unit distribution or otherwise) the Class A Units
into a greater number of units, then the Conversion Price in effect immediately
prior to such subdivision will be proportionately reduced. If Holdings at any
time combines (by reverse unit split or otherwise) the Class A Units into a
smaller number of units, then the Conversion Price in effect immediately prior
to such combination will be proportionately increased.

A. Organic Change.

1. Organic Change Defined. Any recapitalization, reorganization,
reclassification, consolidation or merger of Holdings, which in each case is
effected in such a manner that holders of the Class A Units are entitled to
receive stock or any other securities or property with respect to or in exchange
for such Class A Units is referred to herein as an "Organic Change."

1. Provisions for Organic Change. Prior to the consummation of any Organic
Change, Holdings' Board of Directors will, in good faith, make lawful and
adequate provision to insure that the Subordinated Payee will thereafter have
the right to acquire and receive, in lieu of or addition to (as the case may be)
the Class A Units immediately theretofore acquirable and receivable upon the
conversion of this Subordinated Note, such shares of stock and/or such
securities or property as may be issued or payable with respect to or in
exchange for the Class A Units immediately theretofore acquirable and receivable
upon conversion of this Subordinated Note had such Organic Change not taken
place.

Section 16.

I. SEVERABILITY. If the provisions of this Subordinated Note, or the application
of such provision to any Person or circumstance, shall be held invalid, illegal
or unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining provisions in this Subordinated Note, or the application of
such provision in jurisdictions or to Persons or circumstances other than to
those to which it is held invalid, illegal or unenforceable shall not be
affected thereby.

I. SUBORDINATION.

A. Extent of Subordination to Senior Indebtedness. The Company covenants and
agrees, and the Subordinated Payee, by accepting this Subordinated Note,
covenants and agrees, that, to the extent and in the manner hereinafter set
forth in this Section 10, the indebtedness represented by this Subordinated
Note, whether for principal of, premium, if any, interest on, this Subordinated
Note, and any other Obligation under or in respect hereof and all rights or
claims arising out of or associated with such indebtedness (collectively, the
"Subordinated Obligations"), are hereby expressly made junior and subordinate in
right of payment as provided in this Section 10 to the prior indefeasible
payment and satisfaction in full in cash of all Obligations in respect of all
Senior Indebtedness (including post-petition interest thereon).

                  Any provision of this Subordinated Note to the contrary
notwithstanding, the Company shall not make and the Subordinated Payee shall not
accept, any distribution or payment of any kind whatsoever with respect to the
Subordinated Obligations at any time when any of the Senior Indebtedness remains
outstanding. In no event shall the Subordinated Payee commence any action or
proceeding to contest or otherwise contest the enforceability of the provisions
of this Subordinated Note, the validity, perfection or priority of any security
interests or other liens granted to secure the Senior Indebtedness by the
Company or any other Person, the rights of the Senior Agent or any holders of
Senior Indebtedness or the enforceability of the Senior Credit Agreement.

                  The Company will not give, or permit to be given, and the
Subordinated Payee will not receive, accept or demand, (i) any security of any
nature whatsoever for

<PAGE>

any Subordinated Obligations, on any property or assets, whether now existing or
hereafter acquired, of the Company or any other Credit Party or (ii) any
guarantee, of any nature whatsoever, by the Company or any other Credit Party,
of any Subordinated Obligations.

                  The Subordinated Payee acknowledges and agrees that the
subordination provisions herein are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness, whether such Senior
Indebtedness was created or acquired before or after the issuance of this
Subordinated Note, to acquire and continue to hold, or to continue to hold such
Senior Indebtedness.

                  To the extent that any payment of or distribution in respect
of Senior Indebtedness (whether by or on behalf of the Company , as proceeds of
security or enforcement of any right of setoff or otherwise) is declared to be
fraudulent or preferential, set aside or required to be paid to any receiver,
trustee in bankruptcy, liquidating trustee, agent or other similar Person under
any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then if such payment or distribution is recovered by, or paid over to, such
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person, the Senior Indebtedness or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred. To the extent that the obligation to repay the Senior
Indebtedness is declared to be fraudulent, invalid or otherwise set aside under
any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then the obligation so declared fraudulent, invalid or otherwise set aside (and
all other amounts that would come due with respect thereto had such obligation
not been so affected) shall be deemed to be reinstated and outstanding as Senior
Indebtedness for all purposes hereof as if such declaration, invalidity or
setting aside had not occurred.

A. Distributions and Liquidation, Dissolution, Bankruptcy. In the event of (i)
any distribution of assets of the Company, (ii) any insolvency, or bankruptcy,
case or proceeding, or any receivership, liquidation, reorganization,
arrangement, adjustment, action for the relief of debtors, or other similar case
or proceeding in connection therewith, relative to the Company, its debts, its
operations or to its creditors, as such, or to its assets, or (iii) any
liquidation, dissolution or other winding-up of the Company and whether or not
involving insolvency or bankruptcy, or (iv) any assignment for the benefit of
creditors or any other marshaling of assets or liabilities of the Company, in
each case whether voluntary or involuntary, including, without limitation, the
filing of any petition or the taking of any action to commence any of the
foregoing under any law, foreign or domestic, federal or state (clauses (ii)
through (iv) are referred to as a "Bankruptcy Proceeding"), then and in any such
event:

                  (i) The Senior Agent and the holders of Senior Indebtedness
         shall be entitled to receive indefeasible payment and satisfaction in
         full in cash of all amounts due on or in respect of all Senior
         Indebtedness (including, but not limited to, interest accruing at the
         legal rate on or after the filing of any Bankruptcy Proceeding, and any
         additional interest that would have accrued thereon but for

<PAGE>

         the commencement of such proceeding, whether or not a claim for such is
         allowed in such proceeding), before the Subordinated Payee is entitled
         to receive or retain any payment or distribution of any kind or
         character on account of this Subordinated Note or any Subordinated
         Obligations on this Subordinated Note;

                  (ii) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities, by
         set-off or otherwise, to which the Subordinated Payee would be entitled
         but for the provisions of this Section 10 shall be paid by the Company,
         a liquidating trustee or agent or other Person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the Senior Agent or the
         holders of Senior Indebtedness, ratably according to the aggregate
         amounts remaining unpaid on account of the Senior Indebtedness held or
         represented by each to the extent necessary to make indefeasible
         payment and satisfaction in full in cash of all Senior Indebtedness
         remaining unpaid, after giving effect to any concurrent payment or
         distribution to the Senior Agent or the holders of such Senior
         Indebtedness; and

                  (iii) in the event that, notwithstanding the foregoing
         provisions of this Section 10(b), the Subordinated Payee shall have
         received any payment or distribution of assets of the Company of any
         kind or character, whether in cash, or property or securities,
         including, without limitation, by way of set-off or otherwise, in
         respect of principal of, premium, if any, interest or any Subordinated
         Obligations on this Subordinated Note before all Senior Indebtedness is
         indefeasibly paid in full in cash, then and in such event payment or
         distribution shall be held in trust for the benefit of and shall be
         paid over or delivered forthwith to the trustee in bankruptcy,
         receiver, liquidating trustee, custodian, assignee, agent or other
         Person making payment or distribution of assets of the Company for
         application to the payment of all Senior Indebtedness remaining unpaid,
         to the extent necessary to indefeasibly pay and satisfy all Senior
         Indebtedness in full in cash, after giving effect to any concurrent
         payment or distribution to or for the holders of the Senior
         Indebtedness.

<PAGE>

A. No Payments with Respect to Subordinated Obligations.

1. Unless Section 10(b) shall be applicable, no payment or distribution of any
kind or character (including, without limitation, cash, property and any payment
or distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of this
Subordinated Note) may be made by or on behalf of the Company or accepted by the
Subordinated Payee, including, without limitation, by way of set-off or
otherwise, for or on account of this Subordinated Note or of any Subordinated
Obligations under this Subordinated Note, or for or on account of the purchase,
redemption or other acquisition of this Subordinated Note, and the Subordinated
Payee shall not take or receive from the Company, directly or indirectly in any
manner, payment in respect of all or any portion of this Subordinated Note or of

of the purchase, redemption or other acquisition of this Subordinated Note until
the indefeasible payment and satisfaction in full in cash of all Senior
Indebtedness.

A. When Distribution Must Be Paid Over. In the event that notwithstanding these
provisions, the Subordinated Payee receives any payment or distribution of
assets of the Company of any kind, whether in cash, property or securities,
including, without limitation, by way of set-off or otherwise, in respect of
this Subordinated Note or any Subordinated Obligations under this Subordinated
Note, that the Subordinated Payee is not entitled to receive or retain under the
provisions of this Subordinated Note, then such payment or distribution shall be
held by the Subordinated Payee in trust for the benefit of the Senior Agent and
the Subordinated Payees of Senior Indebtedness, (segregated from other assets
held by the Subordinated Payee) and shall be immediately paid over or delivered
to the Senior Agent in the form received (with any necessary endorsement) to the
extent necessary to make indefeasible payment and satisfaction in full in cash
of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.
In the event of the failure of the Subordinated Payee to endorse or assign any
such payment or distribution, the Senior Agent is hereby irrevocably authorized
to endorse or assign the same.

A. Exercise of Remedies. Until the indefeasible payment and satisfaction in full
in cash of all Senior Indebtedness, the Subordinated Payee (solely in its
capacity as a holder of this Subordinated Note) shall not exercise any rights or
remedies with respect to this Subordinated Note, including, without limitation,
any administrative, legal, equitable or other action (i) to demand or sue for
collection of amounts payable hereunder, (ii) to accelerate the principal of
this Subordinated Note, (iii) to commence or join with any other creditor in

holder of Senior Indebtedness is made an obligee hereunder, and the Senior Agent
and each holder of Senior Indebtedness, whether now outstanding or hereafter
created, incurred, assumed, or guaranteed shall be deemed conclusively to have
acquired or to continue to hold such Senior Indebtedness in reliance upon the
covenants and provisions contained in this Subordinated Note. The Subordinated
Payee acknowledges and agrees that any breach of the provisions of this Section
10 will cause irreparable harm of which the payment of monetary damages may be
inadequate. For this reason, the Subordinated Payee agrees that, in addition to
any remedies at law or in equity to which the Senior Agent or a Subordinated
Payee of the Senior Indebtedness may be entitled, the Senior Agent or a holder
of the Senior Indebtedness will be entitled to an injunction or other equitable
relief to prevent breaches of the provisions of this Section 10 and to compel
specific performance of such provisions.

                  The provisions of this Section 10 are and are intended solely
for the purpose of defining the relative rights of the Subordinated Payee on the
one hand and the Senior Agent and the holders of Senior Indebtedness on the
other hand. Nothing contained in this Section 10 or elsewhere in this
Subordinated Note is intended to or shall impair, as among the Company its
creditors other than the holders of Senior Indebtedness and the Subordinated
Payee, the obligation of the Company, which is absolute and unconditional, to
pay to the Subordinated Payee the principal of, premium, if any, and interest on
this Subordinated Note as and when the same shall become due and payable in
accordance with its terms.

A. Acceleration of Payment of Subordinated Note. If this Subordinated Note is
declared due and payable prior to the Maturity Date, no direct or indirect
payment that is due solely by reason of such declaration shall be made, nor
shall application be made of any distribution of assets of the Company to the
payment, purchase or other acquisition or retirement of this Subordinated Note,
unless, in either case, all Senior Indebtedness shall have been previously
indefeasibly paid and satisfied in full in cash.

A. Voting Rights; Authorization to Effect Subordination. The Senior Agent shall
be entitled to file and prove all claims and to exercise any right to vote of
the Subordinated Payee in respect of this Subordinated Note in connection with a
Bankruptcy Proceeding. Notwithstanding the foregoing, in the event that the
Senior Agent shall allow the Subordinated Payee to retain the right to vote and
otherwise act in a Bankruptcy Proceeding (including, without limitation, the
right to vote to accept or reject any plan of partial or complete liquidation,
reorganization, arrangement, composition or extension), the Subordinated Payee
shall not vote with respect to any such plan or take any other action in any way
so as to contest (x) the validity of any liens or security interests granted to
the Senior Agent, (y) the relative rights and duties of the Senior Agent or the
holders of the Senior Indebtedness established in the Senior Credit Agreement
with respect to such liens and security interests or (z) the enforceability of
the Senior Credit Agreement or these subordination provisions.

<PAGE>

                  The Subordinated Payee hereby irrevocably authorizes , directs
and empowers the Senior Agent, and hereby appoints the Senior Agent to act as
its attorney-in-fact, for any and all of the following purposes, (i) to demand,
sue for, collect and receive all payments and distributions under the terms of
this Subordinated Note, (ii) to file and prove all claims and to exercise any
right to vote in any Bankruptcy Proceeding as set forth above, and (iii) to take
any and all other actions in the name of the Subordinated Payee (solely in its
capacity as a holder of this Subordinated Note), as the Senior Agent determines
in its sole discretion to be necessary or appropriate for the enforcement of the
subordination provisions in this Section 10. The Subordinated Payee further
agrees duly and promptly to take such action as may be requested at any time or
from time to time by the Senior Agent, including, without limitation, executing
and delivering any additional powers of attorney, assignments or proofs of
claims or other instruments and supplying any information and documents, to
enable the Senior Agent to take any of the foregoing actions.

                  Each right, power and remedy of the Senior Agent provided for
in this Subordinated Note or the Senior Credit Agreement, whether now existing
or hereafter available at law or in equity or by statute or otherwise, shall be
cumulative and concurrent and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by the Senior Agent
of any one or more of such rights, powers or remedies shall not preclude the
simultaneous or later exercise of all other such rights, powers or remedies, and
no course of dealing or failure or delay on the part of any party hereto in
exercising any such right, power, or remedy shall operate as a waiver thereof or
otherwise prejudice its rights, powers or remedies.

A. Subrogation. Upon the indefeasible payment and satisfaction in full in cash
of all Senior Indebtedness, the Subordinated Payee shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of, premium, if any, and interest on this
Subordinated Note shall be paid in full. For purposes of such subrogation, no
payments or distributions to the holders of Senior Indebtedness of any cash,
property or securities to which the Subordinated Payee would be entitled except
for the provisions of this Section 10, and no payments over pursuant to the
provisions of this Section 10 to the Senior Agent or the holders of Senior
Indebtedness by the Subordinated Payee shall, as among the Company, its
creditors other than the Senior Agent or the holders of Senior Indebtedness, and
the Subordinated Payee be deemed to be a payment or distribution by the Company
to or on account of the Senior Indebtedness.

                  If any payment or distribution to which the Subordinated Payee
would otherwise have been entitled but for the provisions of this Section 10
shall have been applied, pursuant to the provisions of this Section 10, to the
payment of all amounts payable under the Senior Indebtedness, then and in such
case the Subordinated Payee shall be entitled to receive from the Senior Agent
or the holders of such Senior Indebtedness at the time outstanding any payments
or distributions received by such

<PAGE>

holders of such Senior Indebtedness in excess of the amount sufficient to
indefeasibly pay and satisfy all amounts payable under or in respect of such
Senior Indebtedness in full in cash.

A. Waivers and Consents. The Subordinated Payee waives the right to compel that
any collateral or any other property of the Company or the property of any
guarantor of any Senior Indebtedness or any other Person to be applied in any
particular order to discharge such Senior Indebtedness. The Subordinated Payee
expressly waives the right to require the Senior Agent or the holders of Senior
Indebtedness to proceed against the Company, any collateral or any guarantor of
any Senior Indebtedness or any other Person, or to pursue any other remedy in
the power of the Senior Agent or any such holder which the Subordinated Payee
cannot pursue and which would lighten the Subordinated Payee's burden,
notwithstanding that the failure of any holder of Senior Indebtedness to do so
may thereby prejudice the Subordinated Payee. The Subordinated Payee agrees that
it shall not be discharged, exonerated or have its obligations hereunder to any
holder of Senior Indebtedness reduced by (i) holder's delay in proceeding
against or enforcing any remedy against the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person by the Senior Agent or
any holder of Senior Indebtedness; (ii) the Senior Agent or any holder of Senior
Indebtedness releasing the Company, any collateral or any guarantor of any
Senior Indebtedness or any other Person from all or any part of such Senior
Indebtedness; or (iii) the discharge of the Company, any collateral or any
guarantor of any Senior Indebtedness or any other Person by operation of law or
otherwise, with or without the intervention or omission of the Senior Agent or
any holder of Senior Indebtedness. Any vote by the Senior Agent or any holder of
Senior Indebtedness to accept or reject any plan of reorganization relating to
the Company, any collateral or any guarantor of such Senior Indebtedness or any
other Person, or any receipt by the Senior Agent or any holder of Senior
Indebtedness receipt on account of all or part of any Senior Indebtedness of any
cash, property or securities distributed in any Bankruptcy Proceeding, shall not
discharge, exonerate or reduce the obligations of the Subordinated Payee
hereunder to the Senior Agent and the holders of Senior Indebtedness.

                  No right of the Senior Agent or any present or future holder
of any Senior Indebtedness to enforce the provisions herein shall at any time in
any way be prejudiced or impaired or affected by (i) any act or failure to act
on the part of the Company or by any act or failure to act by the Senior Agent
or any such holder, (ii) any non-compliance by the Company with the terms,
provisions and covenants of this Subordinated Note or the Senior Credit
Agreement, or (iii) any merger or consolidation of the Company or any of its
subsidiaries into or with any other Person, or any sale, lease or transfer of
any or all of the assets of the Company or any of its subsidiaries to any other
Person, regardless in any case of any knowledge thereof of the Senior Agent or
any such holder may have or be otherwise charged with.

                  Without limiting the generality of the foregoing, the Senior
Agent and the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to or knowledge of the Subordinated
Payee, without incurring

<PAGE>

responsibility to the Subordinated Payee and without impairing or releasing the
provisions herein or the obligations hereunder of the Subordinated Payee to the
Senior Agent and the holders of Senior Indebtedness , do any one or more of the
following: (i) change the manner, place or terms of payment or extend the time
of payment of, or renew, alter, compromise or waive any Senior Indebtedness or
otherwise amend, modify or supplement in any manner any Senior Indebtedness or
any instrument evidencing the same or any agreement under which any Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing any Senior Indebtedness;
(iii) release any Person liable in any manner for the collection or payment of
any Senior Indebtedness; (iv) exercise or refrain from exercising any rights
against the Company or any other Person; and (v) fail to perfect a security
interest in any collateral for the payment of the Senior Indebtedness.

                  The Subordinated Payee waives all rights and defenses arising
out of an election of remedies by the Senior Agent or any holder of Senior
Indebtedness, even though that election of remedies, including, without
limitation, any nonjudicial foreclosure with respect to collateral for such
Senior Indebtedness, has impaired the value of the Subordinated Payee's rights
of subrogation, reimbursement or contribution against the Company, any guarantor
of any Senior Indebtedness or any other Person. The Subordinated Payee expressly
waives any rights or defenses it may have by reason of protection afforded to
the Company or any guarantor of any Senior Indebtedness or any other Person with
respect to such Senior Indebtedness pursuant to any anti-deficiency laws or
other laws of similar import which limit or discharge the principal debtor's
indebtedness upon judicial or nonjudicial foreclosure of real property or
personal property collateral for any Senior Indebtedness.

                  The Subordinated Payee agrees that, without the necessity of
any reservation of rights against it, and without notice to or further assent by
it, any demand for payment of any Senior Indebtedness made by the Senior Agent
or any holder of Senior Indebtedness may be rescinded in whole or in part by the
Senior Agent or any such holder, and any Senior Indebtedness may be continued,
and such Senior Indebtedness, or the liability of the Company or any of its
subsidiaries or any other guarantor or any other Person upon or for any part
thereof, or any collateral or guarantee therefor or right of offset with respect
thereto, may, from time to time, in whole or in part, be renewed, extended,
modified, accelerated, compromised, waived, surrendered or released by the
Senior Agent or any holder of such Senior Indebtedness, in each case without
notice to or further assent by the Subordinated Payee and without impairing,
abridging, releasing or affecting the subordination provided for herein.

                  The Subordinated Payee waives any and all notice of the
creation, renewal, extension or accrual of any Senior Indebtedness and notice of
or proof of reliance by the Senior Agent or any holder of Senior Indebtedness
upon the provisions of this Section 10. The Subordinated Payee waives
presentment, protest and demand for payment.

<PAGE>

                  To the maximum extent permitted by law, the Subordinated Payee
waives any claim it might have against the Senior Agent or any holder of Senior
Indebtedness with respect to, or arising out of, any action or failure to act or
any requirement of diligence on the part of the Senior Agent or any such holder
of Senior Indebtedness or any requirement on the part of the Senior Agent or any
such holder of Senior Indebtedness to mitigate damages resulting from any
default under such Senior Indebtedness, any error of judgment, negligence or
mistake or oversight whatsoever on the part of the Senior Agent or any such
holder of Senior Indebtedness or its respective directors, officers, employees
or agents with respect to any exercise of rights or remedies under the
agreements governing or relating to such Senior Indebtedness.

                  The Subordinated Payee, for itself and on behalf of its
successors and assigns, hereby waives any and all now existing or hereafter
arising rights it may have to require the Senior Agent or any holder of Senior
Indebtedness to marshal assets for the benefit of the Subordinated Payee, or to
otherwise direct or receive notice of the timing, order or manner of any sale,
collection or other enforcement of any collateral. Neither the Senior Agent nor
any holder of Senior Indebtedness is under any duty or obligation, and the
Subordinated Payee hereby waives any right it may have to compel the Senior
Agent or any holder of Senior Indebtedness, to pursue any guarantor or other
Person who may be liable for such Senior Indebtedness, or to enforce any lien or
security interest in any collateral.

                  The Subordinated Payee hereby waives and releases all rights
which a guarantor or surety with respect to any Senior Indebtedness could
exercise.

                  The Subordinated Payee hereby waives any duty on the part of
the Senior Agent or any holder of Senior Indebtedness to disclose to it any fact
known or hereafter known by it relating to the operation or financial condition
of the Company or any guarantor of such Senior Indebtedness or their respective
businesses or assets.

                  The Subordinated Payee unconditionally waives (i) notice of
any of the matters referred to in this Section 10, (ii) to the extent permitted
by law, all notices which may be required, whether by statute, rule of law or
otherwise, to preserve intact any rights of the Senior Agent or any holder of
any Senior Indebtedness against the Company, including, without limitation, any
demand, presentment, protest and default, proof of notice of nonpayment under
any Senior Indebtedness and notice of any failure on the part of the Company or
any other Credit Party to perform and comply with any covenant, agreement, term
or condition of the Senior Indebtedness, (iii) any right to the enforcement,
assertion or exercise by the Senior Agent or any holder of any Senior
Indebtedness of any right, power, privilege or remedy conferred in such Senior
Indebtedness or otherwise, and (iv) any notice of any sale, transfer or other
disposition of any Senior Indebtedness by any holder thereof.

A. Subordination to the Sub Debt Indebtedness. The Company covenants and agrees,
and the Subordination Payee by accepting this Subordinated Note covenants and
agrees, that so long as any Sub Debt Default or Sub Debt Event of Default

<PAGE>

shall have occurred and be continuing, no payment of principal of (and premium,
if any) or interest on, or any other payment obligations with respect to, this
Subordinated Note or any judgment with respect hereto shall be made by or on
behalf of the Company or any other Credit Party.

A. Conversion of this Subordinated Note. Notwithstanding anything contained
herein to the contrary, nothing contained in this Section 10 shall prevent any
conversion of this Subordinated Note in accordance with the provisions of
Section 16 hereof.

I. TRANSFERABILITY AND ASSIGNMENT. A Subordinated Payee may not transfer, sell,
pledge, convey, assign or otherwise dispose of ("Transfer") this Subordinated
Note to any other Person without (a) the prior written consent of the Company's
Board of Directors, (b) first delivering to the Company (i) an opinion of
counsel reasonably acceptable in form and substance to the Company (which
counsel must be reasonably acceptable to the Company) that registration under
the Securities Act, or any state or other securities law is not required in
connection with such Transfer and (ii) a written joinder to this Subordinated
Note by the proposed transferee pursuant to which such proposed transferee shall
agree to be bound by the provisions of this Subordinated Note, including Section
10 and (c) so long as any Senior Indebtedness remains outstanding, the prior
written consent of the holders of Senior Indebtedness or any representative of
such holders authorized to give a consent to such joinder and such transferee.
Any transferee executing and delivering such a joinder and thereafter acquiring
this Subordinated Note in accordance with the preceding sentence shall be
referred to herein as a "Permitted Transferee". Any Transfer or attempted
Transfer of this Subordinated Note in violation of any provision of this
Subordinated Note shall be null and void, and the Company shall not record such
Transfer on its books or treat any purported transferee of this Subordinated
Note as the owner of this Subordinated Note for any purpose.

I. COUNTERPARTS. This Subordinated Note may be executed in separate counterparts
each of which shall be an original and all of which taken together shall
constitute one and the same agreement.

I. USURY LAWS. It is the intention of the Company and the Subordinated Payee to
conform strictly to all applicable usury laws now or hereafter in force, and any
interest payable under this Subordinated Note shall be subject to reduction to
the amount not in excess of the maximum legal amount allowed under the
applicable usury laws as now or hereafter construed by the courts having
jurisdiction over such matters. If the maturity of this Subordinated Note is
accelerated by reason of an election by the holder hereof resulting from an
Event of Default, voluntary prepayment by the Company or otherwise, then earned
interest may never include more than the maximum amount permitted by law,
computed from the date hereof until payment, and any interest in excess of the
maximum amount permitted by law shall be canceled automatically and, if
theretofore paid, shall at the option of the Subordinated Payee either be
rebated to the Company or credited on the principal amount of this Subordinated
Note, or if this

<PAGE>

Subordinated Note has been paid, then the excess shall be rebated to the
Company. The aggregate of all interest (whether designated as interest, service
charges, points or otherwise) contracted for, chargeable, or receivable under
this Subordinated Note shall under no circumstances exceed the maximum legal
rate upon the unpaid principal balance of this Subordinated Note remaining
unpaid from time to time. If such interest does exceed the maximum legal rate,
it shall be deemed a mistake and such excess shall be canceled automatically
and, if theretofore paid, rebated to the Company or credited on the principal
amount of this Subordinated Note, or if this Subordinated Note has been repaid,
then such excess shall be rebated to the Company.

I. NO STRICT CONSTRUCTION. The parties hereto have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties hereto, and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

I. AMENDMENTS; WAIVERS. So long as any Senior Indebtedness remains outstanding,
no amendment or modification to or waiver of any provisions of, or the
definitions of any terms appearing in, Section 10, or to or of any other
provision of this Subordinated Note may be made that affects the rights of any
holder of Senior Indebtedness then outstanding unless the holders of such Senior
Indebtedness, or any representative of such holders authorized to give a
consent, consent to such amendment, modification or waiver.

I. CONVERSION.

A. Conversion Procedure.

1. Voluntary Conversion; Automatic Conversion. At any time after the date hereof
and prior to the payment of this Subordinated Note in full, the then
Subordinated Payee may convert this Subordinated Note into a number of Class A
Units determined by dividing (x) the then Convertible Amount (as herein defined)
by (y) $1,000 (the "Conversion Price"). Notwithstanding anything contained
herein to the contrary, if as of May 24, 2001, this Subordinated Note has not
been paid in full, then this Subordinated Note shall automatically be converted
into a number of Class A Units in accordance with the formula contained in the
first sentence of this Section 16(a)(i). If the Subordinated Payee is not a
Member (as such term is defined in the LLC Agreement) at the time of a
conversion of this Subordinated Note, then, at the time of such conversion of
this Subordinated Note, such Subordinated Payee agrees to deliver to the
Secretary of Holdings an executed joinder to the LLC Agreement and any other
documentation necessary in accordance with the requirements of the LLC Agreement
or any of the Related Agreements (as such term is defined in the LLC Agreement).
For purposes of this Subordinated Note, the "Convertible Amount" at any time
shall equal (x) the then outstanding principal amount of this Subordinated Note
plus (y) the interest which has

<PAGE>

then accrued in accordance with the provisions contained herein and which is
then unpaid, in each case, at such time.

1. Effect of Conversion. A conversion of this Subordinated Note will be deemed
to have been effected as of the close of business on the date on which this
Subordinated Note has been surrendered for conversion by the then Subordinated
Payee to the Secretary of Holdings; provided, that in the event of an automatic
conversion of this Subordinated Note, such automatic conversion will be deemed
to have been effected as of the close of business on the date of such automatic
conversion. At such time as such conversion has been effected, the rights of the
then Subordinated Payee (as well as any and all prior Subordinated Payees and
any other former or current holder of this Subordinated Note) under this
Subordinated Note will cease, the Company shall thereafter have no obligation to
make any principal, interest or other payments under this Subordinated Note and
such Subordinated Payee shall be deemed to be the record holder of the
applicable Class A Units which this Subordinated Note shall have then been
converted into. If this Subordinated Note is converted pursuant to this Section
16, no principal amount of, accrued interest on or any other amount pursuant to
this Subordinated Note will be payable at any time as of or after such
conversion.

A. Subdivision or Combination of Class A Units. If Holdings at any time
subdivides (by any unit split, unit distribution or otherwise) the Class A Units
into a greater number of units, then the Conversion Price in effect immediately
prior to such subdivision will be proportionately reduced. If Holdings at any
time combines (by reverse unit split or otherwise) the Class A Units into a
smaller number of units, then the Conversion Price in effect immediately prior
to such combination will be proportionately increased.

A. Organic Change.

1. Organic Change Defined. Any recapitalization, reorganization,
reclassification, consolidation or merger of Holdings, which in each case is
effected in such a manner that holders of the Class A Units are entitled to
receive stock or any other securities or property with respect to or in exchange
for such Class A Units is referred to herein as an "Organic Change."

1. Provisions for Organic Change. Prior to the consummation of any Organic
Change, Holdings' Board of Directors will, in good faith, make lawful and
adequate provision to insure that the Subordinated Payee will thereafter have
the right to acquire and receive, in lieu of or addition to (as the case may be)
the Class A Units immediately theretofore acquirable and receivable upon the
conversion of this Subordinated Note, such shares of stock and/or such
securities or property as may be issued or payable with respect to or in
exchange for the Class A Units immediately theretofore acquirable and receivable
upon conversion of this Subordinated Note had such Organic Change not taken
place.

<PAGE>

A. Pre-Emptive Rights. The Company and the Subordinated Payee acknowledge and
agree to comply with the pre-emptive rights, if any, of Joseph Koff, CMS
Diversified Partners, L.P., CMS Co-Investment Subpartnership and CBC Acquisition
Company, Inc. in connection with any conversion of this Note pursuant to this
Section 16.

I. SEVERABILITY. If the provisions of this Subordinated Note, or the application
of such provision to any Person or circumstance, shall be held invalid, illegal
or unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining provisions in this Subordinated Note, or the application of
such provision in jurisdictions or to Persons or circumstances other than to
those to which it is held invalid, illegal or unenforceable shall not be
affected thereby.
