ITEM 1. DESCRIPTION OF BUSINESS
 
THE COMPANY
 
  ICI is a rapidly growing integrated communications services provider
("ICP"), offering a full suite of local, long distance and enhanced data
telecommunications services to business and government end user customers,
long distance carriers, Internet Service Providers ("ISPs"), resellers and
wireless communications companies. Founded in 1987, the Company is currently
the third largest (based on annualized telecommunications services revenues)
among providers generally referred to as competitive local exchange carriers
("CLECs") after MFS Communications Company, Inc. and Teleport Communications
Group Inc. The Company has sales offices in 23 cities throughout the eastern
half of the United States and offers a full product package of
telecommunications services in 15 metropolitan statistical areas. In April
1996, ICI became one of the first ICPs in the United States to provide
integrated switched local and long distance service and now has five
local/long distance voice switches in service. The Company provides enhanced
data services, including frame relay, asynchronous transfer mode ("ATM") and
Internet access services, primarily to business and government customers
(including over 100 ISPs), in approximately 2,200 cities nationwide, utilizing
89 Company-owned data switches. ICI also serves as a facilities-based
interexchange carrier to approximately 12,000 customers nationwide. ICI
continues to increase its customer base and network density in the eastern
half of the United States and is pursuing attractive opportunities to add
additional services and expand into complementary geographic markets. The
total United States annual market for the Company's local, long distance and
enhanced data services is estimated to be approximately $165 billion, of which
approximately $25 billion is estimated to be addressable by the Company.
 
  The Company's annualized revenue based on the fourth quarter of 1996 (giving
pro forma effect to two recent acquisitions) was $173.7 million. The Company's
revenues have grown from $14.3 million in 1994 to $103.4 million in 1996,
representing a compound annual growth rate of 169%. During the same period,
the Company has increased its sales force from approximately 45 to
approximately 175, increased the number of sales offices from four to 21 and
grown its customer base from 8,148 to 14,133. In 1996, the Company achieved a
significant milestone by introducing local exchange services in its product
portfolio and positioned itself as a provider of integrated telecommunications
services to its customers by (i) obtaining CLEC certification in 13 states and
the District of Columbia (with 22 applications pending), (ii) completing
interconnection co-carrier agreements with six incumbent local exchange
carriers ("ILECs"), (iii) deploying four local/long distance voice switches
and (iv) deploying 37 data switches bringing its total data switches to 89.
 
  Management believes that a well trained team of direct sales and engineering
support professionals, offering customers a full suite of telecommunications
services, is critical to achieving its goal of capturing meaningful market
share in the newly competitive local telecommunications market. By initiating
local switched services in markets where its sales and engineering support
team is already in place, ICI reached a significant milestone toward attaining
this goal. Management believes that being one of the few ICPs offering
integrated local, long distance and enhanced data services to its customers
provides the Company with a competitive advantage in pursuing the estimated
$99 billion national market for local exchange services. The Company's
strategy is to systematically secure a growing portion of a customer's
telecommunications business and through the provision of additional integrated
services, increase the customer's reliance on, and sense of partnership with,
the Company.
 
                                       3
<PAGE>
 
  The Company believes that a significant portion of business and government
customers prefer a single source telecommunications provider that delivers a
full range of efficient and cost effective solutions to their
telecommunications needs. These customers require maximum reliability, high
quality, broad geographic coverage, end-to-end service, solutions-oriented
customer service and the timely introduction of new and innovative services.
The Company is well positioned to satisfy such customer requirements due to
(i) its specialized sales and service approach employing engineering and sales
professionals who design and implement cost-effective telecommunications
solutions, (ii) the ongoing development and integration of new
telecommunications services, (iii) its local/long distance voice switch and
transmission network deployment program, (iv) the implementation of 89
enhanced data switches and over 200 network to network interfaces ("NNIs") for
frame relay data transmission throughout the continental United States and (v)
its interconnection co-carrier agreements with six ILECs.
 
  The Company is certified as a CLEC in 13 states and the District of
Columbia, allowing the Company to provide local exchange services in those
markets, and has CLEC certification applications pending in 22 states. In
addition, ICI is certified as a long distance carrier in 41 states and the
District of Columbia. The Company has nine digital, fiber optic networks in
service and one under development. As of December 31, 1996, this
infrastructure was comprised of 24,122 fiber miles and 655 route miles and was
connected to 487 buildings. As of December 31, 1996, ICI had invested $241.5
million (or 67% of its total invested capital) in gross plant, property and
equipment, principally telecommunications equipment. ICI expects to continue
to grow its networks and has identified expansion opportunities in other
selected markets. Management believes that this expansion will enable the
Company to (i) increase the size of its addressable market and reach a
significant number of new potential customers, (ii) achieve economies of scale
in network operations and sales and marketing and (iii) more effectively
service customers that have a presence in multiple metropolitan areas. The
Company has also undertaken a major expansion of its intercity network,
principally to satisfy the growing demand for interexchange services,
including enhanced data services such as frame relay networking services. As a
result, frame relay nodes have grown from approximately 2,300 nodes, serving
customer locations in 600 cities as of December 31, 1995, to approximately
9,500 nodes, serving customer locations in 2,200 cities as of December 31,
1996.
 
  Enhanced data services, such as those provided on the Company's frame relay
network, are specialized services for customers that need to transport large
amounts of data among multiple locations. According to industry sources, the
frame relay services market is projected to grow from $753 million in 1995 to
$2.7 billion in 1999; however, there can be no assurance that such market
growth will be realized or that the assumptions underlying such projections
are reliable. While the Company has concentrated its frame relay sales in the
eastern half of the United States, ICI is currently the fifth largest national
provider of frame relay networking services (based on number of nodes) after
AT&T, Inc. ("AT&T"), MCI Communications Corporation ("MCI"), Sprint
Corporation ("Sprint") and WorldCom, Inc. ("WorldCom"). In order to satisfy
its customers' desire for end-to-end frame relay services from a single
provider, the Company has deployed its network and made arrangements with
other frame relay service providers to offer national and international
service.
 
  ICI founded the UniSPAN(C) consortium in 1994 with three other carriers to
enable the Company to provide end-to-end frame relay services throughout the
United States and Canada. Because of the high volume of telecommunications
traffic between ICI's target markets and certain Latin American markets, the
Company has entered into international frame relay operating agreements with
ImpSat of Columbia S.A., TresCom International, Telecom Holdings Panama and
Americatel Corporation for the provision of frame relay services to and from
Columbia, Puerto Rico, Panama, Chile & Costa Rica. ICI plans to pursue similar
arrangements to enter other Latin American markets. The Company has pioneered
the interconnection of its frame relay network with those of the ILECs,
allowing pervasive, cost-efficient termination for its customers. Over 200
such NNIs have been implemented with BellSouth Telecommunications Inc.
("BellSouth"), Sprint, GTE Corporation ("GTE"), NYNEX, Bell Atlantic Inc.
("Bell Atlantic") and Southern New England Telecommunications Corp ("SNET").
 
                                       4
<PAGE>
 
  The Company believes that it can effectively utilize its competitive
advantages as a provider of enhanced data services to communications intensive
customers in order to acquire and retain these customers as local exchange and
long distance customers throughout its markets. As ICI continues the
deployment of local/long distance voice switches, it will make more efficient
use of its intercity network. Combining long distance voice traffic between
such switches with the intercity data traffic increases the overall amount of
voice and data traffic that remains completely on the Company's network. The
Company is developing additional applications and deploying technologies that
will provide even greater efficiencies in the use of its intercity network.
 
  The Company has developed and intends to introduce a voice product over its
enhanced data network which will provide a competitive service offering to
customers seeking a lower cost alternative to voice services currently
provided over traditional circuit switched telecommunications networks. The
Company believes that packet switched data networks, such as the Company's,
will displace a significant portion of the estimated $130 billion
telecommunications market which is currently provided over traditional circuit
switched networks. The Company believes this proposed new service offering
will accelerate its penetration of the traditional voice services market.
 
  The Company has developed operating strategies, important components of
which are described below, to increase market share and operating margins.
 
CUSTOMER STRATEGY
 
  Provide Single-Source Telecommunications Services. The Company's service
portfolio includes: local exchange, enhanced data (i.e., frame relay and ATM,
Internet and Intranet), interexchange long distance, integration and private
line services. Management believes that its ability to deliver all of these
services provides significant advantages for both the customer and for the
Company. Not only does this capability address customers' complex requirements
associated with integration of diverse networks and technologies at various
locations, but it also reduces customers' administrative burdens associated
with service charges, billing, network monitoring, implementation,
coordination and maintenance. ICI also believes that by offering expanded,
single-source services through existing networks and customer connections, it
can leverage the significant capacity inherent in its digital networks.
 
  Focus on Business and Government Customers. The Company's portfolio of
service offerings, customer service approach, highly reliable networks, broad
geographic coverage and integration capabilities are well-suited to serve the
demands of telecommunications-intensive business and government customers. The
Company's existing business customer base represents a broad range of
industries, including firms in the retail, financial services, Internet,
healthcare, merchandising, manufacturing and other industry segments. ICI has
a dedicated sales and engineering support group focused exclusively on
providing service to government agencies. The Company has long-term contracts
with the States of Florida and New York pursuant to which the Company provides
various telecommunications services, including frame relay and other data
services (as well as certain voice services under the New York contract).
 
  Develop Interexchange Carrier and Value-Added Reseller Relationships. As a
result of recent changes in state and federal regulation which have provided
ILECs with mandates that foster local exchange competition, ICI has
accelerated its entry into the local exchange services market. As
interexchange carriers ("IXCs") enter the local exchange business, the Company
believes that they will seek to gain access to the local exchange services
market by either developing local network capacity or by purchasing such
capacity from alternative service providers. The Company believes that these
developments are likely to make ICI a candidate for joint ventures and
preferred vendor arrangements with IXCs, ILECs and other telecommunications
related companies. Such arrangements would benefit the Company by enabling ICI
to more rapidly recover its capital investment in switches and other network
infrastructure by increasing the traffic through its networks. These IXC
relationships typically began with the Company providing special access
services on behalf of these IXCs and have recently evolved to include local
access transport and local exchange services. These arrangements should enable
ICI to achieve greater market share and reach new market segments more rapidly
than it could otherwise. The Company
 
                                       5
<PAGE>
 
has also begun soliciting these IXCs, out of region ILECs, cable companies and
other value added resellers to resell the Company's local exchange and other
services. ICI has recently established a preferred vendor relationship with
Cable & Wireless, Inc., which includes the resale of ICI's local exchange
service by Cable & Wireless, Inc.
 
  Maintain and Develop Long-Term Relationships. By providing customized
telecommunications solutions to its customers, the Company develops a sense of
partnership with its customers. This, together with the provision of an
integrated package of services (local, long distance and enhanced data
services) fosters the development of long-term customer relationships. As an
example, the group of ICI's top 42 customers as of December 31, 1994
(representing approximately 68% of ICI's billings for the month of December
1994) had increased their aggregate billings in excess of 100% for the month
of December 31, 1996. At December 31, 1996, 37 of these 42 customers were
still customers of ICI and, in the aggregate, represented approximately 17% of
ICI's monthly billings for December 1996.
 
  Provide Cost-Effective Service Offerings. The Company believes that the
introduction of its services at competitive market rates has stimulated demand
from small to medium-sized customers, thereby broadening the market for ICI's
services. Each of the Company's individually packaged services is
competitively priced, and when integrated into a comprehensive
telecommunications package, typically provides significant savings to such
customers over a combination of ILEC and IXC service offerings.
 
  Expand Solutions-Oriented Sales Effort. The Company has rapidly expanded,
and intends to continue to expand, its direct sales and support team
consisting of engineering and sales professionals. The sales and support teams
have complete product knowledge and technical, integration and program or
project management skills. This team approach promotes a close working
relationship between the Company and the customers' telecommunications,
information services and user constituencies. The Company believes such
relationships improve its ability to sell more of its services and maintain
longer relationships with its customers. During 1996, ICI increased the number
of its sales offices by nine and substantially increased its engineering
support personnel and sales representatives. The Company believes that the
continued deployment of its skilled end user engineering support and sales
team will allow ICI to establish service in new markets and maintain a
competitive position in existing markets. By focusing first on establishing
customer relationships in both new and existing markets, the Company believes
it can efficiently deploy capital in response to actual customer demand.
 
NETWORK STRATEGY
 
  Control Franchise Points of the Networks. Connections to customers and
building entries represent an important component of ICI's network strategy.
These connections provide the Company with the platform to sell a variety of
services to existing and additional potential customers within a building,
analogous to those provided by traditional shared tenant services providers.
ICI believes that the deployment of switching technology and advanced network
electronics enables the Company to better configure its networks to provide
cost-effective and customized solutions to its customers.
 
  Extend Coverage to Provide End-to-End Service. The Company believes that an
important aspect of satisfying its customers is its ability to provide and
support services from end to end. This requires network interconnection with
other carriers and operational support systems and tools to "manage" the
customer's total service. The Company has entered into interconnection co-
carrier agreements with BellSouth, Sprint, GTE, NYNEX, SBC Communications,
Inc. ("SBC") and Bell Atlantic. This will allow the Company to access a large
number of business and government telephones in its service territory. The
Company anticipates entering into similar arrangements with ILECs in other
markets. The Company has also interconnected its frame relay network to
various ILECs, thereby substantially expanding the reach of its networks. ICI
now provides originating and terminating transport services in 45 states and
maintains points of presence ("POPs") for interexchange and enhanced data
services in most major cities in the United States. The Company has deployed,
and continues to integrate, network monitoring and control tools to insure
high levels of service quality and reliability.
 
 
                                       6
<PAGE>
 
  Utilize ILEC Resale and Unbundled Network Elements. Recent regulatory
changes have enabled the Company to resell ILEC services and to utilize
unbundled ILEC network elements at discounted rates. The Company intends to
use resold services and unbundled network elements to provide rapid market
entry and develop its customer base in advance of capital deployment. Once
thresholds of customer density have been achieved, the Company intends to
systematically replace these resold and unbundled elements with its own
facilities, where economical.
 
  Deploy Capital Cost Effectively on a Demand Driven Basis. In addition to the
use of ILEC resale and unbundling, the Company has the ability to lease
network capacity from other carriers at competitive rates. This has led the
Company to lease network capacity in various areas prior to, or as an economic
alternative to, building additional capacity. As a result of its most favored
nation pricing from Advanced Radio Telecom Corp. ("ART") in the Northeast, the
Company from time to time leases 38 GHz wireless services as one such economic
alternative. Utilizing leased facilities enables the Company to (i) meet
customers' needs more rapidly, (ii) improve the utilization of ICI's existing
networks, (iii) add revenue producing customers before building networks,
thereby reducing the risks associated with speculative network construction
and (iv) subsequently focus its capital expenditures in geographic areas where
network construction or acquisition will provide a competitive advantage. The
Company focuses its capital deployment on the segments of its networks that
the Company believes will provide it with the highest revenue and cash flow
potential and the greatest long-term competitive advantage. For the 12 months
ended September 30, 1996, the Company recorded $.54 in revenue for each
average dollar of plant, property and equipment invested.
 
GROWTH STRATEGY
 
  Accelerate Internal Growth. By focusing on business and government customers
and maintaining high-quality and cost-effective services, the Company has
generated a compound annual internal revenue growth rate of 63% for the two
year period ended December 31, 1996. The Company believes that its customer
and network strategies will continue to enable ICI to expand its services and
markets, increase its revenue base and effectively compete in a dynamic
marketplace. In order to achieve such growth, it is essential to continue to
add to the Company's highly skilled, broadly deployed end user sales and
engineering support team.
 
  Accelerate Provision of Local Exchange Services. The Telecommunications Act
of 1996 (the "1996 Act") significantly improved the opportunity for
competition in the local exchange market by mandating that ILECs enter into
arrangements with competitors such as the Company for central office
collocation and unbundling of local services. The Company believes that
implementation of such pro-competitive policies creates favorable
opportunities to more aggressively pursue the provision of local exchange
services. The Company has a total of five local/long distance voice switches
in operation and is currently marketing, to existing and new customers, local
dial tone, switched access termination and origination services, centrex and
desktop products bundled with the Company's other service offerings. The
Company expects to offer such services in all of its fiber optic-based markets
by mid 1997, with the exception of Huntsville, Alabama.
 
  Selectively Acquire Existing Networks and Services. Over the past few years,
a portion of the Company's growth has been accomplished through acquisitions
and joint ventures or selling relationships. The Company continues to examine
various acquisition and joint venture proposals to accelerate its rate of
growth. In addition to the usual financial considerations, ICI assesses each
opportunity to determine if either: (i) current network traffic into and out
of the geographic areas served by the potential joint venture or acquisition
candidate warrants developing a presence in those geographic areas or (ii)
such candidate offers services consistent with the Company's strategy. While
management does not believe that acquisitions are necessary to achieve the
Company's strategic goals, strategic alliances with or acquisitions of
appropriate companies may accelerate achievement of certain goals by creating
operating synergies and providing for a more rapid expansion of the Company's
networks and services. The Company is currently evaluating various acquisition
opportunities. No assurance can be given that any potential acquisition will
be consummated.

1996 ACQUISITIONS
 
  During 1996, the Company completed three corporate acquisitions. In June
1996, the Company acquired the telecommunications division of EMI
Communications Corp. ("EMI"), a company serving customers primarily in the
Northeast with aggregate telecommunications revenues of approximately $53.7
million for the year ended December 31, 1996, of which $27.8 million was
included in the Company's revenue for 1996. ICI purchased EMI's
telecommunications division in exchange for 937,500 newly issued shares of
ICI's common stock, par value $.01 per share (the "Common Stock"), issued to
Newhouse Broadcasting Corporation, the parent corporation of EMI ("Newhouse").
The number of shares of Common Stock payable to Newhouse was based upon a
purchase price of $15,000,000 divided by the average trading price per share
of the Common Stock during the twenty-one day period ending on February 14,
1996 (which was equal to $16.00). As of June 28, 1996, the closing date of the
acquisition, the EMI Shares were valued at approximately $16.9 million. With
this acquisition, the Company substantially expanded its frame relay presence
into the Northeast and acquired both additional customers (including a major
contract with the State of New York) and a number of highly skilled personnel.
 
  In December 1996, the Company acquired Universal Telecom Inc. ("UTT"), a
provider of interexchange services to approximately 1,000 business customers
in the St. Louis area with annualized monthly telecommunications revenues of
approximately $5.4 million. The purchase price was $2.9 million, including
assumed liabilities and shares of Common Stock. The UTT acquisition was
strategically significant because of the near completion of construction of
ICI's St. Louis metropolitan area fiber optic network.
 
  In December 1996, the Company also acquired the network transport business
of NetSolve Incorporated ("NetSolve") for approximately $12.8 million in cash.
With this acquisition the Company gained 600 multi-site business customers and
network facilities (transport and switching) which extended the Company's
intercity network into Texas and provided facilities into incremental markets
in the eastern half of the United States. NetSolve's network transport
business generated approximately $16.0 million of annualized monthly
telecommunications revenues for December 1996.
 
  ICI was incorporated in the State of Delaware on November 9, 1987, as the
successor to a Florida corporation that was founded in 1986. The Company's
principal offices are located at 3625 Queen Palm Drive, Tampa, Florida 33619,
and its telephone number is (813) 829-0011.

</TABLE>
- --------
(1) The Company is currently permitted to offer these services in Florida,
    Alabama, Washington, D.C., Georgia, Illinois, Iowa, Kentucky, Maryland,
    Mississippi, New York, North Carolina, South Carolina, Tennessee and
    Massachusetts and has applied for certification to offer these services in
    22 additional states.
(2) Other includes revenue from pay phones, billing services and intraLATA
    calling services.
 
  The market sizes set forth in the above table are not intended to provide an
indication of the Company's total addressable market or the revenue potential
for the Company's services. ICI has obtained all certifications necessary to
permit the Company to provide local exchange service in 13 states and the
District of Columbia and is in the process of obtaining the necessary
certifications in 22 other states where the Company operates or plans to
operate. In addition, the Company's ability to offer services in its territory
is limited by the size and coverage of the Company's networks and competitive
factors. The Company derives its addressable market estimates by multiplying
the total national market size estimated above by the percentage of the
population (as derived from U.S. Census Bureau information) residing in the
Company's market areas. This estimate assumes that per capita
telecommunications services usage is the same in various regions of the United
States. The Company estimates that its 1997 addressable market, computed under
this methodology, is approximately $34 billion.
 
  ICI's services generally fall into three categories: (i) local network
services, which include local exchange services, special and switched access
services and local private line services, (ii) enhanced data services, which
include frame relay based data transport, ATM and Internet and Intranet
services and (iii) interexchange (long distance) services.
 
  The Company's local network services consist of local private line services,
which the Company has been offering since 1987, and local exchange service,
which the Company began offering in 1996. The Company provides customers local
private line services either by building network facilities or leasing
extended network facilities to the customer's premises. In the markets where
the Company has digital, fiber optic networks, the addition of local exchange
services allows the Company to increase its revenue generating product mix
without
 
                                      12
<PAGE>
 
having to acquire additional transport facilities and allows a more integrated
service to be offered to the customer. The initial circuit used to reach the
customer establishes a platform that can be utilized to offer additional
services. Due to the significant bandwidth inherent in fiber optic cable, a
single connection can support a large number of service types and a large
number of customers.
 
  The Company has built its base of local network service customers by
offering highly reliable, high quality services that compete primarily with
the ILECs. In 1996, local network services accounted for approximately 13% (or
approximately $13.5 million) of the Company's total revenues. The Company
believes that the market for these services will grow through the introduction
of local exchange services, expansion of networks within existing markets,
addition of new markets, and increased penetration of existing customers
through provision of new incremental services.
 
  Enhanced data services consist of interexchange data networks utilizing
frame relay technology and application services, such as Internet, which
utilize the frame relay network. Enhanced data services enable customers to
economically and securely transmit large volumes of data typically sent in
large bursts from one site to another. Previously, customers had to utilize
low speed dedicated private lines or dial up circuits for interconnecting
remote LANs and other customer locations. These methods had numerous
disadvantages including (i) low transmission speeds, (ii) systems that
required the utilization of complementary protocols and line speeds which
significantly increased the cost of implementing networks, (iii) limited
security, placing customers' entire networks at risk to tampering from outside
sources and (iv) high costs due to the necessity to pay for a full time
dedicated line despite infrequent use. Enhanced data services are utilized for
LAN interconnection, remote site, point of sale and branch office
communications solutions.
 
  The typical ICI customer for enhanced data services has multiple business
locations and requires communication for one or more data applications among
these locations. The customer may also have a number of locations served by
ICI's fiber optic networks; however, provision of enhanced data services is
not dependent on the provision of local network services at any specific
location. All of the customers' locations, whether domestic or international,
are monitored by the Company and can be served through the Company's own
operations or through the use of partner networks (e.g., UniSPAN(C)).
 
  As a consequence of a significantly increased volume of traffic and number
of Internet customers connected to ICI's network, many of these customers
connect to other users or Internet hosts without ever leaving ICI's network.
Over 100 ISPs utilize ICI's network for access to their customers and other
Internet sites.
 
  In 1996, the Company's enhanced data services accounted for approximately
31% of the Company's total revenue. The market for enhanced data services,
according to industry sources, is expected to grow from $1.3 billion in 1996
to $2.7 billion in 1999. There can be no assurance, however, that such market
growth will be realized or that the assumptions underlying such projections
are reliable.
 
  Long distance services have been offered by the Company since December 1994.
Long distance services include inbound (800) service, outbound service and
calling card telephone service. The Company currently provides interLATA long
distance services in 41 states, interstate long distance services nationwide
and international termination worldwide.
 
  The Company's integration services are applicable to all three categories of
service described above and are made available to end user and carrier
customers. A team of sales professionals and engineers develop specialized
solutions for a customer's specific telecommunications needs. Some of these
integration services include the sale, configuration and installation of third
party equipment to handle certain telecommunications and monitoring functions
and the development of private networks. The Company believes that such
services increase the level of linkage between the Company's and the
customer's operations thereby increasing the customer's reliance on the
Company.
 
                                      13

  The Company plans to continue to expand its domestic geographic reach by
acquiring and integrating high quality, value added companies. In addition,
the Company, through the pursuit of strategic alliances, plans to expand its
ability to originate and terminate voice and data traffic in certain Latin
American markets beyond those recently established in Panama, Columbia, Puerto
Rico, Chile and Costa Rica. ICI believes these markets are important to its
business because, not only is there a significant community of interest
between many of these countries and certain key cities in ICI's service
territory as a result of the large Spanish speaking populations in these
cities, but there are also a number of businesses that have operations in both
Latin America and in the Company's southeastern markets.
 
SALES, MARKETING AND SERVICE DELIVERY
 
  ICI's marketing activities are primarily directed to business and government
customers with a presence in the Company's service territory. The Company's
customers include large corporations, financial services companies, government
departments and agencies, and academic, scientific and other major
institutions as well as small and medium sized businesses and IXCs.
 
  The Company's sales and marketing approach is to build long-term business
relationships with its customers, with the intent of becoming the single
source provider of all of their telecommunications services. In an effort to
leverage its recent success in obtaining government contracts, the Company has
created a sales group whose focus is the marketing of ICI's telecommunications
services to government departments and agencies. The Company has also
established a sales group that focuses exclusively on obtaining building entry
agreements with owners of multiple office building complexes. The ICI sales
force includes specialized professionals who focus on sales to retail,
wholesale and alternate channel (agents and value added resellers) consumers
of the Company's telecommunications services. The Company's sales staff works
to gain a better understanding of the customer's operations in order to
develop innovative, application-specific solutions to each customer's needs.
Sales personnel locate potential business customers by several methods,
including customer referral, market research, cold calling and other
networking alliances, including customer demand information from certain IXCs.
 
  Enhanced data services, like all other ICI services, are sold through the
Company's existing sales force, supported by sales engineers, and often in
cooperation with agents and value added resellers (independent providers of
communications hardware to customers) and other business associates. This
approach enables the Company to (i) emphasize the applications solutions
aspects of enhanced data services and (ii) utilize the expertise and resources
of other vendors. The Company intends to continue expanding its sales and
engineering support staff and other technical specialists in order to meet the
growing demand for enhanced data services. Since these services are also sold
to extended network customers of the Company, this sales effort offers the
Company a means of expanding its network. See "--Network."
 
  New customer relationships are typically established by providing services
from one of the three major categories (local, enhanced and long distance),
then following up with additional services from the other two categories. For
instance, during 1996, the Company established approximately 2,800 new
customer relationships through the sale of long distance services.
 
  The Company's service delivery staff is primarily responsible for
coordinating service and installation activities. Service delivery activities
include surveying the site to assess ambient conditions and power, and space
requirements, as well as coordinating installation dates and equipment
delivery and testing. ICI's customer service and technical staff plans,
engineers, monitors and maintains the integrity, quality and availability of
the Company's networks. ICI's customer service and technical staff are
available to customers 24 hours every day.
 
  To support all of its network based services, the Company has implemented an
automated ordering, provisioning and billing system similar to that used by
the ILECs. This automated system makes it easy for the Company's IXC customers
to track their orders with ICI, and similarly allows ICI to track its orders
with the ILECs. ICI has also implemented an integrated network management
system which enhances the Company's ability to monitor, test, track trouble
and dispatch repair resources. This system monitors the performance of ICI's
networks and services 24 hours every day.

NETWORK
 
  The Company has deployed its network infrastructure selecting the most
economical alternative of constructing or leasing facilities or a combination
thereof. The Company generally chooses to own facilities where (i) there is no
fiber optic network alternative and the Company can be the incumbent network
provider, (ii) ownership creates strategic value for the Company, (iii) large
concentrations of telecommunications traffic are accessible, or have been
secured, to justify network construction and (iv) network construction can
create significant barriers to entry for subsequent competitors who may wish
to enter the Company's markets.
 
  In addition to the "build" vs. "lease" decision for network deployment, the
Company also considers potential network acquisitions from time to time. The
Company believes that acquisitions will generally provide it with (i)
immediate access to incremental customers, (ii) reduction of network
construction and implementation risks, (iii) elimination of an incumbent
competitor, (iv) immediate access to additional qualified management, sales
and technical personnel and (v) a network platform for the provision of
incremental value added services. The Company has demonstrated such strategy
with its acquisition of FiberNet, EMI and NetSolve.
 
  In those markets where ICI chooses to deploy broadband fiber networks, the
Company's strategy is to first develop the "carrier ring" portion of its
network, a high capacity network designed to be accessible to all the major
long distance carriers and key ILEC central offices in the area. This portion
of the network allows the Company to provide access to these long distance
carriers, provide connectivity to the ILEC network for interconnection and use
of unbundled ILEC network elements, and over time, to connect business and
government customers to such long distance carriers. Second, the Company
designs a larger "backbone ring" extending from the carrier ring, with a view
toward making the network accessible to the largest concentration of
telecommunications-intensive business and government customers in the area.
Hubs are strategically located on the backbone rings to allow for the
collection and distribution of telecommunications traffic onto and off the
backbone ring. Third, the Company concentrates its sales and marketing efforts
on adding business and government customers located on or very near its
backbone network and hub locations. Once ICI determines that there is
sufficient customer demand in a particular area, it extends "distribution
rings" from the backbone ring to reach specific business customers in that
area. The Company's emphasis is on the building and expansion of these city-
based networks to reach end user customers in buildings or office parks with
substantial telecommunications opportunity. The establishment of a "franchise
point" at a customer's location is a key strategic design element of these
networks.
 
  ICI's city-based networks are comprised of fiber optic cables, integrated
switching facilities, advanced electronics, data switching equipment (e.g.
frame relay and ATM), transmission equipment and associated wiring and
equipment. By virtue of its state-of-the-art equipment and ring-like
architecture, the Company's networks offer electronic redundancy and diverse
access routing. Through automatic protection switching, if any electrical
component or fiber optic strand fails, the signal is instantaneously switched
to a "hot standby" component or fiber. Since network outages and transmission
errors can be very disruptive and costly to long distance carriers and other
customers, consistent reliability is critical to customers.
 
  The Company currently has fiber optic networks in service in the Orlando,
Tampa, Miami, St. Petersburg, Jacksonville, and West Palm Beach, Florida,
Cincinnati, Ohio, Raleigh-Durham, North Carolina, and Huntsville, Alabama
metropolitan areas and one under development in St. Louis, Missouri. ICI
continues to expand these networks and has identified similar network
expansion opportunities in other selected markets.
 
  As a result of its acquisition of EMI in 1996, ICI also utilizes certain
wireless technologies as a part of its provision of services. ICI owns a long-
haul microwave transmission system comprising approximately 5,000 route miles
in the Northeast, which is principally used for transporting digital
interexchange trunking and analog video signals. Additionally, as a part of a
1995 Asset Purchase Agreement between EMI and ART, ICI has access to 38 GHz
licenses in most metropolitan areas in the Northeast at the lowest rate
charged by ART for such services. The Company uses this technology from time
to time to connect its customers to its network, allowing rapid initiation of
service.
 
                                      15
<PAGE>
 
  In addition, the Company has undertaken a significant network expansion to
satisfy the demands of the Company's market driven growth in interexchange
data and voice offerings. The Company has deployed resources, primarily
switching equipment, to develop an extensive network to provide these
services. Excess capacity on this primarily leased network can be used to
provide incremental telecommunications services such as interexchange long
distance services.
 
  The Company has recently undertaken the deployment of ATM networking
technology in its intercity network, allowing the network capacity to be
efficiently shared between multiple platforms. Often, the Company offers
interexchange services in geographic markets where it has not deployed its own
fiber optic network by leasing facilities from a variety of entities,
including ILECs, utilities, IXCs, local governments, cable companies and
various transit/highway authorities. In many cases, such capacity is obtained
through the capital lease or purchase of "dark fiber." The combination of the
Company's city-based networks and its intercity capacity comprise the seamless
network platform which the Company utilizes to offer its broad array of
telecommunications services to its customers. The Company also has agreements
with certain third parties and the carriers in the UniSPAN(C) consortium to
deliver enhanced data services nationwide or internationally through a
seamless data network.
 
  The Company's telecommunications equipment vendors actively participate in
planning and developing electronic equipment for use in ICI's networks. The
Company does not believe it is dependent on any single vendor for equipment.
Because the Company uses existing telecommunications technology rather than
developing it, ICI's research and development expenditures are not material.
 
COMPETITION
 
  The Company faces intense competition in each of its three service
categories--local services, enhanced services and long distance services.
 
  The Company believes that various legislative initiatives, including the
recently enacted 1996 Act and certain state initiatives, will result in the
removal of the remaining regulatory barriers to local exchange competition.
While the Company currently competes with AT&T, MCI and others in the
interexchange services market, the 1996 Act also permits the RBOCs to provide
interexchange services upon meeting certain requirements described in the 1996
Act. When the RBOCs begin to provide such services, they will be in a position
to offer single source service similar to that being offered by ICI. In
addition, Sprint and GTE offer, and various ILECs and IXCs, including
BellSouth, have announced their intent to offer, integrated telecommunication
services in areas currently served by ICI. AT&T and MCI have begun to enter
the local exchange services market. The Company cannot predict the number of
competitors that will emerge as a result of existing and any new federal and
state regulatory or legislative actions. Competition from integrated
telecommunications services provided by the RBOCs, AT&T, MCI, Sprint, WorldCom
and others could have a material adverse effect on the Company's business.
 
  Competition in each of the service categories provided by the Company, as
well as for systems integration which is common to all market segments, is
discussed below.
 
  Local Services. In each of its geographic markets, the Company faces
significant competition for the local services it offers from RBOCs and other
ILECs, which currently dominate their local telecommunications markets. These
companies all have long-standing relationships with their customers and have
financial, personnel and technical resources substantially greater than those
of ICI.
 
  The Company also faces competition in most markets in which it operates from
one or more CLECs or ICPs operating fiber optic networks. Other local service
providers have operations or are initiating operations within one or more of
the Company's service areas. ICI expects WorldCom, MCI, Teleport
Communications Group, Inc. ("Teleport"), and certain cable television
providers, many of which are substantially larger and have substantially
greater financial resources than the Company, to enter some or all of the
markets that the Company
 
                                      16
<PAGE>
 
presently serves. At least two of these competitors, WorldCom and Teleport,
have entered or announced plans to enter a number of ICI's service areas. ICI
also understands that other entities have indicated their desire to enter the
local exchange services market within specific metropolitan areas served or
targeted by ICI.
 
  In addition, a continuing trend toward consolidation and strategic alliances
within the telecommunications industry could result in significant new
competition for the Company. AT&T and MCI have begun to enter the local
services market. Other potential competitors of the Company include utility
companies, long distance carriers, wireless telephone systems and private
networks built by individual business customers. The Company cannot predict
the number of competitors that will emerge as a result of existing or any new
federal and state regulatory or legislative actions.
 
  Competition in all of the Company's geographic market areas is based on
quality, reliability, customer service and responsiveness, service features
and price. The Company has kept its prices at levels competitive with those of
the ILECs while providing, in the opinion of the Company, a higher level of
service and responsiveness to its customers.
 
  Although the ILECs are generally subject to greater pricing and regulatory
constraints than other local network service providers, ILECs are achieving
increasing pricing flexibility for their local services as a result of recent
legislative and regulatory developments. The ILECs have continued to lower
rates, resulting in downward pressure on certain dedicated and switched access
transport rates. This price erosion has decreased operating margins for these
services. However, the Company believes this effect will be more than offset
by the increased revenues available as a result of access to customers
provided through interconnection co-carrier agreements and the opening of
local exchange service to competition. In addition, the Company believes that
lower rates for dedicated access will benefit other services offered by the
Company.
 
  Enhanced Data Services. The Company faces competition in its enhanced data
services business from ILECs, IXCs, VSAT providers and others. Many of the
Company's existing and potential competitors have financial and other
resources significantly greater than those of the Company.
 
  The Company competes with the larger IXCs on the basis of service
responsiveness, rapid response to technology and service trends, and a
regional focus borne of early market successes. All of the major IXCs,
including AT&T, MCI, Sprint and WorldCom offer frame relay services and
several of the major IXCs have announced plans to provide Internet services.
The Company believes it competes favorably with these providers in its
markets, based on the features and functions of its services, the high density
of its networks, relatively greater experience and in-house expertise.
Continued aggressive pricing is expected to support continued rapid growth,
but will place increasing pressure on operating margins.
 
  The Company also competes with VSAT services on the basis of price and data
capacity. The Company believes that the relatively low bandwidth of each VSAT
terminal and the cost of purchasing and installing VSAT equipment limits the
ability of VSAT to compete with the frame relay services provided by the
Company.
 
  Many of the ILECs now offer services similar to ICI's enhanced data
services, but offer them only on an intraLATA basis. While the ILECs generally
cannot interconnect their frame relay networks with each other, ICI has
interconnected its frame relay network with those of various ILECs. As a
result, ICI can use certain ILEC services to keep its own costs down when
distributing into areas that cannot be more economically serviced on its own
network. ICI expects the ILECs to aggressively expand their enhanced data
services as regulatory developments permit them to deploy interLATA long
distance networks. When the ILECs are permitted to provide such services, they
will be in a position to offer single source service similar to that being
offered by ICI. As part of its various interconnection agreements, ICI has
negotiated favorable rates for unbundled ILEC frame relay service elements.
The Company expects such negotiations to decrease its costs, positively
impacting margins for this service.
 
                                      17
<PAGE>
 
  Interexchange Services. The Company currently competes with AT&T, MCI and
others in the interexchange services market. Many of the Company's competitors
have longstanding relationships with their customers and have financial,
personnel and technical resources substantially greater than those of ICI. In
providing interexchange services, the Company focuses on quality service and
economy to distinguish itself in a very competitive marketplace. ICI has built
a loyal customer base by emphasizing its customer service. The additional new
services that are offered as the Company implements its local exchange
services should further support this position by allowing the Company to
market a wide array of fully integrated telecommunications services. While
these services are subject to highly competitive pricing pressures, the
Company's cost to provide these services is decreasing as it deploys more
local/long distance voice switches and interexchange network facilities.
 
  Systems Integration. The Company faces competition in its systems
integration business from equipment manufacturers, the RBOCs and other ILECs,
long distance carriers and systems integrators, many of which have financial,
and other resources significantly greater than those of the Company. Because
the Company is not highly dependent on system integration revenues and because
the Company typically provides system integration services to customers who
purchase other services of the Company, ICI's systems integration competitors
should not pose a significant threat to ICI's overall business.
 
GOVERNMENT REGULATION
 
  Overview. The Company's services are subject to varying degrees of federal,
state and local regulation. The FCC exercises jurisdiction over all facilities
of, and services offered by, telecommunications common carriers to the extent
those facilities are used to provide, originate or terminate interstate or
international communications. The state regulatory commissions retain
jurisdiction over most of the same facilities and services to the extent they
are used to originate or terminate intrastate communications. In addition,
many of the regulations issued by these regulatory bodies may be subject to
judicial review, the result of which ICI is unable to predict.
 
  Federal Regulation. The Company must comply with the requirements of common
carriage under the Communications Act of 1934 (the "Communications Act"), as
amended. Comprehensive amendments to the Communications Act were made by the
1996 Act, which was signed into law on February 8, 1996. The 1996 Act effected
plenary changes in regulation at both the federal and state levels that affect
virtually every segment of the telecommunications industry. The stated purpose
of the 1996 Act is to promote competition in all areas of telecommunications
and to reduce unnecessary regulation to the greatest extent possible. While it
will take years for the industry to feel the full impact of the 1996 Act, it
is already clear that the legislation provides the Company with both new
opportunities and new challenges.
 
  The 1996 Act gives the FCC the authority to forebear from regulating
companies if it finds that such regulation does not serve the public interest,
and directs the FCC to review its regulations for continued relevance on a
regular basis. As a result of this directive, a number of the regulations that
historically applied to the Company have been and may continue to be
eliminated in the future. While it is therefore expected that a number of
regulations that were developed prior to the 1996 Act will be eliminated in
time, those which still apply to the Company at present are discussed below.
 
  The FCC has established different levels of regulation for dominant and non-
dominant carriers. Of domestic common carrier service providers, only GTE and
the RBOCs are classified as dominant carriers, and all other providers of
domestic common carrier services, including the Company, are classified as
non-dominant carriers. The 1996 Act provides the FCC with the authority to
forebear from imposing any regulations it deems unnecessary, including
requiring non-dominant carriers to file tariffs. On November 1, 1996, in its
first major exercise of regulatory forbearance authority granted by the 1996
Act, the FCC issued an order detariffing domestic interexchange services. The
order requires mandatory detariffing and gives carriers such as ICI nine
months to withdraw federal tariffs and move to contractual relationships with
its customers. This order subsequently was stayed by a federal appeals court
and it is unclear at this time whether the detariffing order will be
implemented.
 
                                      18
<PAGE>
 
  The 1996 Act greatly expands the FCC's interconnection requirements on the
ILECs. The 1996 Act requires the ILECs to: (i) provide physical collocation,
which allows companies such as ICI and other interconnectors to install and
maintain their own network termination equipment in ILEC central offices, and
virtual collocation only if requested or if physical collocation is
demonstrated to be technically infeasible; (ii) unbundle components of their
local service networks so that other providers of local service can compete
for a wider range of local services customers; (iii) establish "wholesale"
rates for their services to promote resale by CLECs and other competitors;
(iv) establish number portability, which will allow a customer to retain its
existing phone number if it switches from the ILEC to a competitive local
service provider; (v) establish dialing parity, which ensures that customers
will not detect a quality difference in dialing telephone numbers or accessing
operators or emergency services; and (vi) provide nondiscriminatory access to
telephone poles, ducts, conduits and rights-of-way. In addition, the 1996 Act
requires ILECs to compensate competitive carriers for traffic originated by
the ILECs and terminated on the competitive carriers' networks. The FCC is
charged with establishing national guidelines to implement the 1996 Act. The
FCC issued its Interconnection Order on August 8, 1996, after which, six
separate motions were filed with the Eighth Circuit Court of Appeals in St.
Louis for a stay of the FCC's Interconnection Order. On October 15, 1996, the
court stayed the pricing and "most favored nation" provisions contained in the
Interconnection Order while leaving in place the structural aspects of the
order. The Eighth Circuit Court is expected to render a decision by June 1997
on the merits of the FCC's interconnection rules and that decision is expected
to be appealed to the United States Supreme Court.
 
  As part of its pro-competitive policies, the 1996 Act frees the RBOCs from
the judicial orders that prohibited their provision of interLATA services.
Specifically, the Act permits RBOCs to provide long distance services outside
their local service regions immediately, and will permit them to provide in-
region interLATA service upon demonstrating to the FCC and state regulatory
agencies that they have adhered to the FCC's interconnection regulations.
BellSouth in Georgia and North Carolina and Ameritech Corporation
("Ameritech") in Michigan have asked their respective state regulatory
agencies to review their applications and to recommend approval by the FCC.
These RBOCs are expected to file their applications with the FCC by June 1997.
The FCC is expected to scrutinize these and future applications to ensure that
the interconnection requirements have been met.
 
  As a result of these provisions of the 1996 Act, the Company has taken the
steps necessary to be a provider of local exchange services and has positioned
itself as a full service, integrated telecommunications services provider. ICI
has obtained local certification in 13 states and the District of Columbia and
has applications pending for local certification in 22 additional states. In
addition, the Company has successfully negotiated interconnection agreements
that meet the interconnection provisions contained in the 1996 Act with six
ILECs. At the same time, the 1996 Act also makes competitive entry more
attractive to RBOCs, other ILECs, interexchange carriers and other companies,
and likely will increase the level of competition that the Company faces.
 
  The 1996 Act also repeals the telecommunications/cable television cross-
ownership prohibition which generally had prohibited ILECs from providing in-
region cable television service.
 
  The 1996 Act's interconnection requirements also apply to interexchange
carriers and all other providers of telecommunications services, although the
terms and conditions for interconnection provided by these carriers are not
regulated as strictly as interconnection provided by the ILECs. This may
provide the Company with the ability to reduce its own access costs by
interconnecting directly with non-ILECs, but may also cause the Company to
incur additional administrative and regulatory expenses in replying to
interconnection requests.
 
  While the 1996 Act reduces regulation to which non-dominant local exchange
carriers are subject, it also reduces the level of regulation that applies to
the ILECs, and increases their ability to respond quickly to competition from
the Company and others. For example, in accordance with the 1996 Act, the FCC
has proposed to subject the ILECs to "streamlined" tariff regulation, which
greatly accelerates the time in which tariffs that change service rates take
effect, and eliminates the requirement that ILECs obtain FCC authorization
before constructing new domestic facilities. These actions will allow ILECs to
change service rates more quickly in
 
                                      19
<PAGE>
 
response to competition. The FCC initiated a proceeding on December 24, 1996
that addresses these issues and is expected to issue an order on these issues
in May 1997. Similarly, the FCC has initiated a proceeding to review its price
cap rules that may permit significant new pricing flexibility to ILECs. To the
extent that such increased pricing flexibility is provided, the Company's
ability to compete with ILECs for certain services may be adversely affected.
 
  The 1996 Act directs the FCC, in cooperation with state regulators, to
establish a Universal Service Fund that will provide subsidies to carriers
that provide service to under-served individuals and high cost areas. These
proceedings, which must be concluded in May 1997, may require the Company to
contribute to the Universal Service Fund, but may also allow the Company to
receive payments from the Fund if it is deemed eligible. The Company also may
provide service to under-served customers in lieu of making Universal Service
Fund payments. The net revenue effect of these regulations on the Company
cannot be determined at this time.
 
  In an order released on October 18, 1995, the FCC found that the transport
of frame relay service should be classified as a "basic" service. Previously,
it was common practice in the industry for many carriers to consider frame
relay an "enhanced" service. This decision was significant because the FCC
requires that basic services be tariffed, but permits enhanced services to be
offered on an off-tariff basis. As a result of the FCC's decision, all
carriers that provide frame relay transport were required to include the
service in their federal tariffs by May 6, 1996. The Company has included its
frame relay service in its federal tariff. The "basic" and "enhanced"
terminology used by the FCC is a regulatory term of art denoting the
classification of services for tariffing purposes. This regulatory use of the
term should not be confused with the Company's description of a class of
services-frame relay, ATM and Internet services-as "enhanced" elsewhere in
this document.
 
  State Regulation. To the extent that the Company provides intrastate
service, it is subject to the jurisdiction of the relevant state public
service commissions. The Company currently provides some intrastate services
in 36 states and is subject to regulation by the public service commissions of
those states. The Company is currently certificated (or certification is not
required) in 41 states and the District of Columbia to provide toll services
and is currently seeking certification in the nine remaining states. The
Company is certified as a CLEC in 13 states and the District of Columbia and
is currently seeking CLEC certification in 22 additional states. The Company
is constantly evaluating the competitive environment and may seek to further
expand its intrastate certifications into additional jurisdictions.
 
  The 1996 Act preempts state statutes and regulations that restrict the
provision of competitive local services. As a result of this sweeping
legislation, the Company will be free to provide the full range of intrastate
local and long distance services in all states in which it currently operates,
and any states into which it may expand. While this action greatly increases
the Company's addressable customer base, it also increases the amount of
competition to which the Company may be subject.
 
  Many of the states in which the Company operates have also enacted
legislation or regulations that have permitted, or will permit, local service
competition. The 1996 Act will require most of the states to modify these
policies to bring them into conformity with federal standards. The 1996 Act
also authorizes the states to adopt additional regulations to the extent that
they do not conflict with federal standards. This aspect of the FCC's order
has been challenged and is awaiting resolution in court. It is unclear at this
time how the states will respond to the new federal legislation, and what
additional regulations they may adopt.
 
  While the 1996 Act's prohibition of state barriers to competitive entry took
effect on February 8, 1996, there have been numerous procedural delays which
must be resolved before the 1996 Act's policies are fully implemented. The
Company continues to support efforts at the state government level to
encourage competition in their markets under the federal law and to permit
ICPs and CLECs to operate on the same basis and with the same rights as the
ILECs. In addition, the Company has been successful in its pursuit of local
certificates from state Commissions and negotiated interconnection agreements
with the ILECs, which permit the Company to meet its business objectives
despite the uncertain regulatory environment.
 
                                      20
<PAGE>
 
  In most states, the Company is required to file tariffs setting forth the
terms, conditions and prices for services that are classified as intrastate
(local, toll and enhanced). Most states require the Company to list the
services provided and the specific rate for each service. Under different
forms of regulatory flexibility, the Company may be allowed to set price
ranges for specific services, and in some cases, prices may be set on an
individual customer basis. The Company is not subject to price cap or rate of
return regulation in any state in which it is currently certificated to
provide local exchange service.
 
  As the Company expands its operations into other states, it may become
subject to the jurisdiction of their respective public service commissions for
certain services offered by ICI. The Company does not believe that its
relationship with Latin American or other international service providers
currently subjects it to (or will subject it to) regulation outside the United
States.
 
  Local Government Authorizations. The Company may be required to obtain from
municipal authorities street opening and construction permits to install and
expand its fiber optic networks in certain cities. In some cities, local
partners or subcontractors may already possess the requisite authorizations to
construct or expand the Company's networks.
 
  In some of the areas where the Company provides service, it may be subject
to municipal franchise requirements and may be required to pay license or
franchise fees based on a percent of gross revenue. There are no assurances
that certain municipalities that do not currently impose fees will not seek to
impose fees in the future, nor is there any assurance that, following the
expiration of existing franchises, fees will remain at their current levels.
In many markets, other companies providing local telecommunications services,
particularly the ILECs, currently are excused from paying license or franchise
fees or pay fees that are materially lower than those required to be paid by
the Company. The 1996 Act requires municipalities to charge nondiscriminatory
fees to all telecommunications providers, but it is uncertain how quickly this
requirement will be implemented by particular municipalities in which the
Company operates or plans to operate or whether it will be implemented without
a legal challenge initiated by the Company or another ICP or CLEC.
 
  If any of the Company's existing network agreements were terminated prior to
their expiration date and the Company was forced to remove its fiber optic
cables from the streets or abandon its network in place, even with
compensation, such termination could have a material adverse effect on the
Company.
 
  The Company also must obtain licenses to attach facilities to utility poles
in order to build and expand facilities. Because utilities that are owned by
cooperatives or municipalities are not subject to federal pole attachment
regulation, there is no assurance that the Company will be able to obtain pole
attachment from these utilities at reasonable rates, terms and conditions.
 
AGREEMENTS
 
  Interconnection Co-carrier Agreements. The Company has recently entered into
interconnection co-carrier agreements with BellSouth, NYNEX, SBC, GTE, Sprint
and Bell Atlantic, and is in the process of negotiating a similar agreement
with Ameritech. Each of these agreements, among other things, provides for
mutual and reciprocal compensation, local interconnection, resale of local
exchange services, access to unbundled network elements, service provider
number portability and access to operator service, directory service and 911
service, as provided for in the 1996 Act. The agreements further provide that
additional terms and conditions will be set by negotiation between the parties
relating to issues which arise that were not originally contemplated by the
agreements. These agreements were executed within the past year and have terms
ranging from two to three years.
 
  Network Agreements. The Company has built its digital fiber optic networks
pursuant to various rights-of-way, conduit and dark fiber leases, utility pole
attachment agreements and purchase arrangements (collectively, the "Network
Agreements"). Substantially all of the Network Agreements (other than utility
pole attachment agreements, which typically can be terminated on 90 days
notice) are for a long-term and include renewal options.
 
  Although none of the Network Agreements are exclusive, the Company believes
that conduit space, fiber availability and other physical constraints make it
unlikely that the lessors under the various Network Agreements could easily
make similar arrangements available to others. The Company believes that its
 
                                      21
<PAGE>
 
relationships with its lessors are satisfactory. Certain of the Network
Agreements require ICI to make revenue sharing payments or, in some cases, to
provide a fixed price alternative or dark fiber to the lessor without an
additional charge. In addition, the Company has various other performance
obligations under its Network Agreements, the breach of which could result in
the termination of such agreements. Further, actions by governmental regulatory
bodies could, in certain instances, also result in the termination of certain
Network Agreements. The cancellation of any of the material Network Agreements
could materially adversely affect the Company's business in the affected
metropolitan area. See "Risk Factors--Risk of Cancellation or Non-Renewal of
Network Agreements, Licenses and Permits."
 
  Interexchange Agreements. ICI, from time to time, enters into purchase
agreements with interexchange carriers for the transport and/or termination of
long distance calls outside of its territory. These contracts are typically two
years in duration and customarily include minimum purchase amounts.
 
  UniSPAN(C). In order to provide end-to-end connectivity and interoperability
throughout the United States to its enhanced data services customers, ICI
entered into a frame relay service agreement (the "UniSPAN Agreement") in
September 1994 with EMI (since acquired by ICI), PacNet, Inc., Integrated
Network Services, Inc. and MRC Telecommunications, Inc. In September 1995,
Telemedia International, Inc., an international telecommunications company,
became a party to the UniSPAN Agreement. Pursuant to the UniSPAN Agreement,
each of the parties agreed to (i) provide frame relay services on its networks
to each of the other parties, subject to available capacity and agreement as to
certain terms including price and access to facilities, and (ii) use reasonable
efforts to utilize the services of the other parties in the event that such
party requires frame relay services in a geographic location not served by its
own networks. The UniSPAN Agreement has an initial three year term with
successive one year renewal periods until terminated by a majority vote of the
parties. However, any party may withdraw from the agreement as of the
expiration of any term by giving 60 days prior written notice thereof.
Throughout the term of the UniSPAN Agreement and for one year thereafter, or
for a period of one year after the withdrawal of any party, none of the parties
may solicit provision of frame relay services to customers which were brought
in to the UniSPAN(C) program by another party or for which frame relay services
were requested by another party.
 
EMPLOYEES
 
  As of December 31, 1996, ICI employed a total of 874 full-time employees. The
Company anticipates that the number of employees will increase significantly
throughout 1997. The Company believes that its future success will depend in
large part on its continued ability to attract and retain highly skilled and
qualified personnel. ICI has nondisclosure agreements with all of its
employees. The Company also regularly uses the services of contract technicians
for the installation and maintenance of its networks. None of ICI's employees
is represented by a collective bargaining agreement. ICI believes that its
relations with its employees are good.
 
RISK FACTORS
 
  Limited Operations of Certain Services; History of Net Losses. The Company's
business commenced in 1987. Substantially all of the Company's revenues are
derived from local exchange services, enhanced data services, long distance
services, integration services and certain local network services. Many of
these services have only recently been initiated or their availability only
recently expanded in new market areas. The Company is expecting to
substantially increase the size of its operations in the near future. Given the
Company's limited operating history, there is no assurance that it will be able
to compete successfully in the telecommunications business.
 
  The development of the Company's business and the expansion of its networks
require significant capital, operational and administrative expenditures, a
substantial portion of which are incurred before the realization of revenues.
These capital expenditures will result in negative cash flow until an adequate
customer base is established. Although its revenues have increased in each of
the last three years, ICI has incurred significant increases in expenses
associated with the installation of local/long distance voice switches and
expansion of its fiber optic networks, services and customer base. ICI reported
net losses of approximately $3.1 million, $20.7
 
                                       22
<PAGE>
 
million and $57.2 million for the years ended December 31, 1994, 1995 and
1996, respectively. The Company anticipates having a significant net loss in
1997 that is expected to be substantially greater than the loss in 1996 and
expects net losses to continue for the next several years. In addition, the
Company expects to have negative EBITDA in 1997. There can be no assurance
that ICI will achieve or sustain profitability or positive EBITDA in the
future.
 
  Significant Capital Requirements and Need for Additional
Financing. Expansion of the Company's existing networks and services and the
development of new networks and services require significant capital
expenditures. ICI expects to fund its capital requirements through existing
resources, joint ventures, debt or equity financing, and internally generated
funds. The Company expects that to continue to expand its business will
require raising substantial additional equity and/or debt capital after 1998.
The Company's outstanding debt instruments do not permit the incurrence of an
amount of indebtedness sufficient to fund its anticipated future capital
requirements. Accordingly, the Company will need to obtain waivers or consents
from its debtholders or raise equity capital. There can be no assurance,
however, that ICI will be successful in raising sufficient debt or equity
capital on terms that it will consider acceptable. In addition, the Company's
future capital requirements will depend upon a number of factors, including
marketing expenses, staffing levels and customer growth, as well as other
factors that are not within the Company's control, such as competitive
conditions, government regulation and capital costs. Failure to generate
sufficient funds may require ICI to delay or abandon some of its foreign
expansion or expenditure, which would have a material adverse effect on its
growth and its ability to compete in the telecommunications industry.
 
  Expansion Risk. The Company is experiencing a period of rapid expansion
which management expects will increase in the near future. This growth has
increased the operating complexity of the Company as well as the level of
responsibility for both existing and new management personnel. The Company's
ability to manage its expansion effectively will require it to continue to
implement and improve its operational and financial systems and to expand,
train and manage its employee base. The Company's inability to effectively
manage its expansion could have a material adverse effect on its business.
 
  A portion of the Company's expansion may occur through acquisitions as an
alternative to direct investments in the assets required to implement the
expansion. No assurance can be given that suitable acquisitions can be
identified, financed and completed on acceptable terms, or that the Company's
future acquisitions, if any, will be successful or will not impair the
Company's ability to service its outstanding obligations.
 
  Risks of Implementation; Need to Obtain Permits and Rights of Way. The
Company is continuing to expand its existing networks. The Company has
identified other expansion opportunities in the eastern half of the United
States and is currently extending the reach of its networks to pursue such
opportunities. There can be no assurance that the Company will be able to
expand its existing networks or construct or acquire new networks as currently
planned on a timely basis. The expansion of the Company's existing networks
and its construction or acquisition of new networks will be dependent, among
other things, on its ability to acquire rights-of-way and any required permits
on satisfactory terms and conditions and on its ability to finance such
expansion, acquisition and construction. In addition, the Company may require
pole attachment agreements with utilities and ILECs to operate existing and
future networks, and there can be no assurance that such agreements will be
obtained or obtainable on reasonable terms. These factors and others could
adversely affect the expansion of the Company's customer base on its existing
networks and commencement of operations on new networks. If the Company is not
able to expand, acquire or construct its networks in accordance with its
plans, the growth of its business would be materially adversely affected.
 
  Competition. In each of its markets, the Company faces significant
competition for the local network services, including local exchange services,
it offers from ILECs, which currently dominate their local telecommunications
markets. ILECs have long-standing relationships with their customers which
relationships
 
                                      23
<PAGE>
 
may create competitive barriers. Furthermore, ILECs may have the potential to
subsidize competitive service from monopoly service revenues. In addition, a
continuing trend toward business combinations and alliances in the
telecommunications industry may create significant new competitors to the
Company. The Company also faces competition in most markets in which it
operates from one or more ICPs and CLECs operating fiber optic networks. In
addition, the Company faces competition in its network systems integration
business from equipment manufacturers, the RBOCs and other ILECs, long distance
carriers and systems integrators, and in its enhance data services business
from local telephone companies, long distance carriers, very small aperture
terminal ("VSAT") providers and others. Many of the Company's existing and
potential competitors have financial, personnel and other resources
significantly greater than those of the Company.
 
  The Company believes that various legislative initiatives, including the
recently enacted 1996 Act, have removed remaining legislative barriers to local
exchange competition. Nevertheless, in light of the passage of the 1996 Act,
regulators are also likely to provide ILECs with increased pricing flexibility
as competition increases. If ILECs are permitted to lower their rates
substantially or engage in excessive volume or term discount pricing practices
for their customers, the net income or cash flow of ICPs and CLECs, including
the Company, could be materially adversely affected. In addition, while the
Company currently competes with AT&T, MCI and others in the interexchange
services market, the recent federal legislation permits the RBOCs to provide
interexchange services once certain criteria are met. Once the RBOCs begin to
provide such services, they will be in a position to offer single source
service similar to that being offered by ICI. In addition, AT&T and MCI have
entered and other interexchange carriers have announced their intent to enter
into the local exchange services market, which is facilitated by the 1996 Act's
resale and unbundled network element provisions. The Company cannot predict the
number of competitors that will emerge as a result of existing or new federal
and state regulatory or legislative actions. Competition from the RBOCs with
respect to interexchange services or from AT&T, MCI or others with respect to
local exchange services could have a material adverse effect on the Company's
business.
 
  Regulation. The Company is subject to varying degrees of federal, state and
local regulation. The Company is not currently subject to price cap or rate of
return regulation, nor is it currently required to obtain FCC authorization for
the installation, acquisition or operation of its network facilities. Further,
the FCC has issued an order holding that non-dominant carriers, such as the
Company, are not required to file interstate tariffs for domestic long distance
service on an ongoing basis. That order has been stayed by a federal appeals
court and it is not clear at this time whether the detariffing order will be
implemented. Until further action is taken by the court, the Company will
continue to maintain tariffs for these services. The FCC also requires the
Company to file interstate tariffs on an ongoing basis for international
traffic and access services. The Company is generally subject to certification
and tariff or price list filing requirements for intrastate services by state
regulators. Although passage of the 1996 Act should result in increased
opportunities for companies that are competing with the ILECs, no assurance can
be given that changes in current or future regulations adopted by the FCC or
state regulators or other legislative or judicial initiatives relating to the
telecommunications industry would not have a material adverse effect on the
Company. In addition, although the 1996 Act provides incentives to the ILECs
that are subsidiaries of RBOCs to enter the long distance service market by
requiring ILECs to negotiate interconnection agreements with local competitors,
there can be no assurance that these ILECs will negotiate quickly with
competitors such as the Company for the required interconnection of the
competitor's networks with those of the ILECs.
 
  Potential Diminishing Rate of Growth. During the period from 1994 to 1996,
the Company's revenues have grown at a compound annual growth rate of 169%.
While the Company expects to continue to grow, as its size increases it is
likely that its rate of growth will diminish.
 
  Risk of New Service Acceptance by Customers. The Company has recently
introduced a number of services, primarily local exchange services, that the
Company believes are important to its long-term growth. The success of these
services will be dependent upon, among other things, the willingness of
customers to accept
 
                                       24
<PAGE>
 
the Company as the provider of such new telecommunications technology. No
assurance can be given that such acceptance will occur; the lack of such
acceptance could have a material adverse effect on the Company.
 
  Rapid Technological Changes. The telecommunications industry is subject to
rapid and significant changes in technology. While ICI believes that, for the
foreseeable future, these changes will neither materially affect the continued
use of its fiber optic networks nor materially hinder its ability to acquire
necessary technologies, the effect on the business of ICI of technological
changes such as changes relating to emerging wireline and wireless
transmission technologies, including software protocols, cannot be predicted.
 
  Dependence on Key Personnel. The Company's business is managed by a small
number of key management and operating personnel, the loss of certain of whom
could have a material adverse impact on the Company's business. The Company
believes that its future success will depend in large part on its continued
ability to attract and attain highly skilled and qualified personnel. None of
the Company's key executives, other than David C. Ruberg, President, Chief
Executive Officer and Chairman of the Board, is a party to a long-term
employment agreement with the Company.
 
  Risk of Cancellation or Non-Renewal of Network Agreements, Licenses and
Permits. The Company has lease and/or purchase agreements for rights-of-way,
utility pole attachments, conduit and dark fiber for its fiber optic networks.
Although the Company does not believe that any of these agreements will be
cancelled in the near future, cancellation or non-renewal of certain of such
agreements could materially adversely affect the Company's business in the
affected metropolitan area. In addition, the Company has certain licenses and
permits from local government authorities. The 1996 Act requires that local
government authorities treat telecommunications carriers in a competitively
neutral, non-discriminatory manner, and that most utilities, including most
ILECs and electric companies, afford alternative carriers access to their
poles, conduits and rights-of-way at reasonable rates on non-discriminatory
terms and conditions. There can be no assurance that the Company will be able
to maintain its existing franchises, permits and rights or will be able to
obtain and maintain the other franchises, permits and rights needed to
implement its strategy on acceptable terms.
 
  Dependence on Business from IXCs. For the year ended December 31, 1996,
approximately 10% of the Company's consolidated revenues were attributable to
access services provided to IXCs. The loss of access revenues from IXCs in
general could have a material adverse effect on the Company's business.
See""Business--Customer Strategy."
 
  In addition, the Company's growth strategy assumes increased revenues from
IXCs from the deployment of local/long distance voice switches on its networks
and the provision of switched access origination and termination services.
There is no assurance that the IXCs will continue to increase their
utilization of the Company's services, or will not reduce or cease their
utilization of the Company's services, which would have a material adverse
effect on the Company.
 
  Business Combinations; Change of Control. The Company has from time to time
held, and continues to hold, preliminary discussions with (i) potential
strategic investors who have expressed an interest in making an investment in
or acquiring the Company and (ii) potential joint venture partners looking
toward the formation of strategic alliances that would expand the reach of the
Company's networks or services without necessarily requiring an additional
investment in the Company. In addition to providing additional growth capital,
management believes that an alliance with an appropriate strategic investor
would provide operating synergy to, and enhance the competitive positions of,
both ICI and the investor within the rapidly consolidating telecommunications
industry. There can be no assurance that agreements for any of the foregoing
will be reached. An investment, business combination or strategic alliance
could constitute a change of control. The terms of the Company's Existing
Senior Notes (as defined) and Series A Preferred Stock (as defined) provide
that a change of control would require the Company to repay the indebtedness
and redeem the Series A Preferred Stock outstanding under such instruments. If
a change of control does occur, there is no assurance that the
 
                                      25
<PAGE>
 
Company would have sufficient funds to make such repayments and redemption or
could obtain any additional debt or equity financing that could be necessary
in order to repay the Existing Senior Notes (as defined) and to redeem the
Series A Preferred Stock.
 
  Forward Looking Statements. The statements contained in this report that are
not historical facts are "forward-looking statements" (as such term is defined
in the Private Securities Litigation Reform Act of 1995), which can be
identified by the use of forward-looking terminology such as "estimates,"
"projects," "anticipates," "expects," "intends," "believes," or the negative
thereof or other variations thereon or comparable terminology, or by
discussions of strategy that involve risks and uncertainties. Management
wishes to caution the reader that these forward-looking statements, such as
the Company's plans to expand its existing networks or to build and acquire
networks in new areas, the market opportunity presented by larger metropolitan
areas, its anticipation of installation of switches or the provision of local
exchange services and revenues from designated markets during 1997, and
statements regarding development of the Company's businesses, the estimate of
market sizes and addressable markets for the Company's services and products,
the Company's anticipated capital expenditures, regulatory reform and other
statements contained in this report regarding matters that are not historical
facts, are only estimates or predictions. No assurance can be given that
future results will be achieved; actual events or results may differ
materially as a result of risks facing the Company or actual results differing
from the assumptions underlying such statements. Such risks and assumptions
include, but are not limited to, the Company's ability to successfully market
its services to current and new customers, generate customer demand for its
services in the particular markets where it plans to market services, access
markets, identify, finance and complete suitable acquisitions, design and
construct fiber optic networks, install cable and facilities, including
switching electronics, and obtain rights-of-way, building access rights and
any required governmental authorizations, franchises and permits, all in a
timely manner, at reasonable costs and on satisfactory terms and conditions,
as well as regulatory, legislative and judicial developments that could cause
actual results to vary materially from the future results indicated, expressed
or implied, in such forward-looking statements.
 
  Moreover, the Company presents certain data contained herein on an
annualized basis, based on quarterly or monthly data, because the Company
believes that such annualized data is a standard method to present certain
data in the telecommunications industry. However, actual annual results could
differ materially from annualized data because annualized data does not
account for factors such as seasonality, cyclicability, growth or decline.
Consequently, readers should not place undue reliance on the annualized data.
 
ITEM 2. DESCRIPTION OF PROPERTIES
 
  The Company leases its principal administrative, marketing, warehouse and
service development facilities in Tampa, Florida and leases other space for
storage of its electronics equipment and for administrative, sales and
engineering functions in other cities where the Company operates networks
and/or performs sales functions. The Company believes that its properties are
adequate and suitable for their intended purposes.
 
  As of December 31, 1996, the Company's total telecommunications and
equipment in service consisted of fiber optic telecommunications equipment
(53%), fiber optic cable (16%), furniture and fixtures (8%), leasehold
improvements (2%) and construction in progress (21%). Such properties do not
lend themselves to description by character and location of principal units.
Fiber optic cable plant used in providing service is primarily on or under
public roads, highways or streets, with the remainder being on or under
private property. Substantially all of the Company's telecommunications
equipment is housed in multiple leased facilities in various locations
throughout the metropolitan areas served by the Company.
 
  Equipment additions over the past five years include gross additions to
telecommunications equipment having an estimated service life of one year or
more. Additions, including capital leases and excluding equipment
 
                                      26

ITEM 3. LEGAL PROCEEDINGS

  Holders of shares of Common Stock are entitled to dividends, when and if
declared by the Board of Directors, out of funds legally available therefor.
ICI has never declared or paid cash dividends on its Common Stock. ICI intends
to retain its earnings, if any, to finance the development and expansion of
its business, and therefore does not anticipate paying any dividends in the
foreseeable future. In addition, the terms of (i) the Company's 13 1/2% Series
B Senior Notes due 2005 (the "Senior Notes"), (ii) the Company's 12 1/2%
Senior Discount Notes due 2006 (the "Discount Notes" and together with the
Senior Notes, the "Existing Senior Notes") and (iii) the Company's Series A
Preferred Stock restrict the payment of dividends. When such restrictions no
longer exist, the decision whether to pay dividends will be made by the Board
of Directors in
 
                                      27

light of conditions then existing, including the Company's results of
operations, financial condition and capital requirements, business conditions
and other factors. The payment of dividends on the Common Stock is also
subject to the preference applicable to the outstanding shares of the
Company's Series A Preferred Stock and to the preference that may be
applicable to any additional outstanding shares of the Company's Preferred
Stock.
 
  On June 28, 1996, ICI purchased EMI's telecommunications division in
exchange for 937,500 newly and validly issued, fully paid and nonassessable
shares of Common Stock (the "EMI Shares"), issued by ICI to Newhouse, the
parent corporation of EMI. The number of EMI Shares payable to Newhouse was
based upon a purchase price of $15,000,000 divided by the average trading
price per share of the Common Stock during the twenty-one day period ending on
February 14, 1996 (which was equal to $16.00). As of June 28, 1996, the
closing date of acquisition, the EMI Shares were valued at approximately $16.9
million. The EMI Shares were transferred to Newhouse pursuant to an exemption
from registration provided for under Section 4(2) of the Securities Act of
1933, as amended (the "Act"). Prior to the issuance of the EMI Shares,
Newhouse represented to ICI, among other things, that: (i) it is acquiring the
EMI Shares for its own account for investment and without any view to any
distribution thereof; (ii) it understands that it must bear the economic risk
of its investment in the EMI Shares for an indefinite period of time; and
(iii) it is aware of the Company's business affairs and financial condition
and has acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the EMI Shares.
 
  On December 6, 1996, the Company acquired certain assets of UTT for a
purchase price of $2.9 million, including assumed liabilities and 31,380
unregistered shares of Common Stock (the "UTT Shares"). The UTT Shares were
issued by ICI to UTT pursuant to an exemption from registration provided for
under Section 4(2) of the Act. Prior to the issuance of the UTT Shares, UTT
represented to ICI, among other things, that: (i) it is acquiring the UTT
Shares for its own account for investment purposes and without any view to
distribution of thereof; (ii) it understands that it must bear the economic
risk of its investment in the UTT Shares for an indefinite period of time; and
(iii) it is aware of the Company's business affairs and financial condition
and has acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the UTT Shares.
 
  On March 7, 1997, ICI consummated a private placement (the "Private
Placement") of 30,000 shares of its 13 1/2% Series A Redeemable Exchangeable
Preferred Stock due 2009, liquidation preference $10,000 per share (the
"Series A Preferred Stock"), to "qualified institutional buyers" (as defined
in Rule 144A under the Securities Act of 1933, as amended (the "Act")) (the
"Purchasers") to generate gross proceeds to the Company of $300,000,000,
including an aggregate of $11,125,000 of underwriting discounts and
commissions. The shares of Series A Preferred Stock were issued to the
Purchasers pursuant to an exemption from registration provided by Rule 144A
under the Act. In connection with the Private Placement, the Purchasers and
the Company entered into a Registration Rights Agreements, whereby the Company
agreed to file a registration statement with respect to an offer to exchange
the Series A Preferred Stock for a new issue of preferred stock of the Company
registered under the Act, with terms substantially identical to those of the
Series A Preferred Stock. Each of the Purchasers represented to the Company,
among other things, that it is a qualified institutional buyer and is aware
that the sale to it is being made in reliance on Rule 144A, and that it is
acquiring the Series A Preferred Stock for its own account or for the account
of another qualified institutional buyer.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
audited Consolidated Financial Statements and the Notes thereto appearing
elsewhere in this report.
 
OVERVIEW
 
  Since its inception in 1987, the Company has experienced substantial growth.
Building from its original base in Florida, ICI is now a provider of
integrated telecommunications services to customers that have a presence in
the eastern half of the United States. The Company currently has nine digital,
fiber optic networks in service and one under development. In addition, the
Company's frame relay network serves customers in approximately 2,200 cities
and provides end-to-end connectivity throughout the United States and many
international markets. As its networks and service offerings have expanded,
the Company has experienced significant year to year growth in revenues and
customers.
 
  ICI competes with the ILECs and IXCs in its service territory and offers a
full range of voice and data telecommunications services. ICI's customers
include a broad range of business and government end users and IXCs. The
Company delivers local network services, including local exchange service,
primarily over digital fiber optic telecommunications networks that it either
owns or leases. In some circumstances, leasing facilities enables the Company
to more rapidly initiate service to customers, reduces the risk of network
construction or acquisition and potentially improves cash flow due to the
reduction or deferment of capital expenditures. The Company also offers
enhanced data services to its customers on an extensive intercity network that
connects its customers, either through its own network or through other
carriers, to locations throughout the country and internationally. This
intercity network combined with the Company's local/long distance voice
switches allows the Company to provide interexchange long distance service
domestically and internationally.
 
  At its inception, ICI provided special access and private line services to
IXC's. In 1988, ICI was the first telecommunications service provider in
Florida to begin providing special access and private line services to
business customers. In 1991, ICI began offering integration services in
response to customers' needs and in 1992, ICI introduced its first enhanced
data services to provide flexible capacity and highly reliable end-to-end data
service for its business and government customers. The Company began offering
interexchange long distance service in December 1994, Internet services in
1995 and local exchange services in 1996. The pace with which the Company has
introduced new service offerings has enabled it to achieve substantial growth,
improve its mix of customers and diversify its sources of revenue. The Company
believes that business and government customers will continue to account for a
substantial share of its revenues over the next several years, because of
ICI's ability to offer such customers integrated, cost-effective
telecommunications solutions. The Company believes that during the first few
years of local exchange competition, the IXCs may enter the market by becoming
resellers of the Company's local services. If the IXCs pursue a reseller
strategy, the amount of revenue the Company realizes from carriers may
increase during this period.
 
  From 1992 through 1995, the Company had achieved positive EBITDA and
increased its revenue base substantially. However, as a result of significant
investments in resources necessary to launch local exchange services and
expand enhanced data services, EBITDA decreased as a percentage of revenue and
the Company's EBITDA was negative for 1996. This was due to the significant up
front expenses related to the development of its networks and leased
facilities, the revenue from which is expected to be realized in later
periods. The development of the Company's business and the installation and
expansion of its networks have resulted in substantial capital expenditures
and net losses during this period of its operations. Procurement of rights-of-
way, administration and maintenance of facilities, depreciation of network
capital expenditures and sales, general and administrative costs will continue
to represent a large portion of the Company's expenses during its rapid
expansion. In addition, the Company is experiencing rapid growth in marketing
and selling expenses consistent with the addition of new customers and an
increased level of selling and marketing activity. All of the marketing and
selling expenses associated with the acquisition of new customers are expensed
as they are incurred even though these customers are expected to generate
recurring revenue for the Company for several years. The continued expansion
of the Company's networks in anticipation of new customers and the marketing
of services
 
                                      31
<PAGE>
 
to new and existing customers is therefore adversely impacting EBITDA of the
Company in the near term. The Company anticipates, but there can be no
assurance, that as its customer base grows, incremental revenues will be
greater than incremental operating expenses.
 
PLAN OF OPERATION
 
  In 1997 and beyond, the Company believes that its growth will be balanced
among its local exchange, long distance and enhanced data services. Based on
the Company's analysis of FCC data and its knowledge of the industry, the
Company estimates that the market for local exchange, long distance and data
services was approximately $25 billion in 1996 in the Company's service
territory. As a result of the Company's planned expansion in 1997, the Company
expects to be positioned to provide these services in markets with a total
opportunity of approximately $34 billion by the end of 1997.
 
  In order to develop its businesses more rapidly and efficiently utilize its
capital resources, ICI plans to use the existing fiber optic infrastructure of
other providers in addition to using its existing networks. While the Company
will use significant amounts of capital to deploy enhanced data and voice
switches on a demand driven basis in selected markets, ICI believes that its
substantial existing network capacity should enable it to add new customers
and provide additional services that will result in increased revenues with
lower incremental costs and, correspondingly, over time improve its EBITDA.
For example, selling additional services, such as local exchange services, to
existing or new customers allows the Company to utilize unused portions of the
capacity inherent in its existing fiber optic networks. This operating
leverage increases the utilization of the network with limited additional
capital expenditures. The Company's strategy to offer a full complement of
telecommunications services is designed to enable the Company to take
advantage of the operating leverage of its networks.

  Since the Company's founding in 1987, ICI has continually introduced new
services. Due to these efforts, ICI's customer and revenue base has expanded
substantially in recent years. The Company believes that the continued
aggressive expansion of its enhanced data and interexchange voice services and
the continued deployment of local exchange services will accelerate the
diversification of the Company's customer and revenue base. The Company
believes the expansion of the Company's customer base and the diversification
of its revenue sources have (i) lowered the Company's reliance on any one
customer, (ii) increased the total addressable market for the Company's
services and (iii) reduced the Company's percentage of revenue associated with
services to IXCs. The table set forth below provides an analysis of the
Company's customer and revenue base.

</TABLE>
 
  The increase in revenue was derived principally from growth in the Company's
local network services, enhanced data services and interexchange services. EMI
contributed $27.8 million to the growth during the last six months of 1996, of
which $20.5 million related to interexchange services and $7.3 million related
to enhanced data services. The Company acquired the telecommunications
division of EMI in June 1996. The Company's annualized monthly recurring
revenue increased to $12.3 million at December 31, 1996 from $3.3 million at
December 31, 1995, an increase of 273%. Monthly recurring revenue represents
the monthly service charges billable to telecommunications service customers
as of the last day of the period indicated and excludes nonrecurring revenues
for certain one-time charges, such as installation fees or equipment sales.
The increase in the level of enhanced data services was evidenced by the
increase in nodes which grew approximately 313% from approximately 2,300 at
December 31, 1995 to approximately 9,500 at December 31, 1996. The geographic
coverage of the Company's networks also grew in 1996 primarily through the
acquisitions of EMI, UTT and NetSolve and the expansion of the Company's
intercity network. Monthly recurring revenue in the backlog (booked sales that
have yet to be installed) at December 31, 1996 was approximately $4.8 million
annualized, a 14.3% increase from the prior year. From December 31, 1995 to
December 31, 1996, the number of fiber miles in the Company's networks
increased from 17,128 to 24,122; route miles increased from 504 to 655; and
the number of customers served by ICI increased from 9,530 to 14,133.
 
                                      33

  Operating expenses in total increased by 186% from $48.2 million for 1995 to
$137.6 million in 1996, a $89.4 million increase. Of the increase,
approximately $25.9 million, $1.9 million and $.5 million were attributable to
the inclusion of EMI, NetSolve and UTT operating expenses, respectively. The
operating results of EMI have been included in the consolidated results since
July 1, 1996. NetSolve and UTT operating results have been included in the
consolidated results since December 1, 1996. The balance of the increase was
consistent with the significant expansion of the Company's owned and leased
networks and equipment sales to customers.
 
  Facilities administration and maintenance and line costs increased $58.1
million or 253% to $81.1 million in 1996 from $23.0 million in 1995. Of the
increase, approximately $20.9 million, $.9 million and $.4 million were
attributable to the inclusion of EMI, NetSolve and UTT operating results,
respectively. In addition, increases in leased network capacity associated
with the growth of local network service, enhanced data service and
interexchange service revenues, increases in maintenance expense due to
network expansion, payroll expense increases due to hiring additional
engineering and operations staff along with increased cost of goods sold
related to equipment sold to customers contributed to the change.
 
  Selling, general and administrative expenses increased to $36.6 million in
1996 from $15.0 million in 1995, an increase of $21.6 million or 144%. The
increase in expense is primarily related to increased sales commissions as a
result of increases in sales bookings, in addition to increased sales,
customer service, marketing and management information systems and payroll
expense along with related costs, including one-time recruitment, relocation
and training expenses. Of the increase, approximately $2.7 million was
attributable to the inclusion of EMI operating results. Selling, general and
administrative expenses in 1996 include $.9 million of amortization of
deferred compensation expense related to the Company's 1996 Long-Term
Incentive Plan. Unamortized deferred compensation to be amortized into expense
over approximately the next 5 years amounts to $7.6 million.
 
  Depreciation and amortization expense increased to $19.8 million in 1996
from $10.2 million in 1995, an increase of $9.6 million or 95%. These
increases are directly related to the $149.6 million and $34.9 million of
telecommunications equipment additions (including capital leases and business
acquisitions) in 1996 and 1995, respectively, relating to ongoing network
expansion.
 
  Interest expense increased to $35.2 million in 1996 from $13.8 million in
1995, an increase of $21.4 million or 156%. This increase is the result of
interest expense on the May 1996 issuance of $330 million principal amount of
the Company's 12 1/2% Discount Notes and the effect of a full year of interest
expense on the June 1995 issuance of $160 million principal amount of the
Company's 13 1/2% Senior Notes. Included in the $35.2 million of interest
expense for 1996 was $14.3 million of interest on the 12 1/2% Discount Notes
which was accreted into principal without a cash outlay.
 
  Interest and other income increased to $12.2 million in 1996 from $4.1
million in 1995, an increase of $8.1 million or 200%, resulting from interest
income earned on the excess proceeds of the May 1996 issuance of $330 million
principal amount of the 12 1/2% Discount Notes and the issuance of 4,674,503
shares of Common Stock, at $26.00 per share, combined with a full year of
interest income earned on the excess proceeds of the June 1995 issuance of
$160 million principal amount of the 13 1/2% Senior Notes.
 
  Extraordinary loss of $1.6 million in 1995 reflects $1.2 million in
prepayment penalties related to certain indebtedness which was repaid from the
proceeds of the June 1995 issuance of $160 million principal amount of 13 1/2%
Senior Notes and the write-off of the unamortized deferred financing costs
associated with the indebtedness repaid.
 
  EBITDA for 1996 decreased $15.0 million in 1996 from $.6 million in 1995 to
$(14.3) million in 1996. As a percentage of revenue, 1996 and 1995 EBITDA were
approximately (13.8%) and 1.7%, respectively. This decline was the result of
the acceleration in the deployment of ICI's capital expansion plan which
significantly increased growth oriented expenses (such as increases in sales,
customer service and market development costs) prior to realizing revenues
associated with these expenditures.

  A substantial portion of the increase in revenue was derived from growth in
the Company's enhanced data services and the revenues of Phone One, Inc.
("Phone One") (interexchange services) for the full year in 1995. The Company
acquired all of the outstanding common stock of Phone One on December 2, 1994.
Monthly recurring revenue increased to $2.9 million at December 31, 1995 from
$2 million at December 31, 1994, an increase of 45%. Monthly recurring revenue
represents the monthly service charges billable to telecommunications service
customers as of the last day of the period indicated and excludes nonrecurring
revenues for certain one-time charges, such as installation fees or equipment
charges. The increase in the level of enhanced data services was evidenced by
the increase in nodes which grew approximately 156% from approximately 900 at
December 31, 1994 to approximately 2,300 at December 31, 1995. The geographic
coverage of the Company's networks also grew in 1995 primarily through the
acquisition of FiberNet USA, Inc. and FiberNet Telecommunications of
Cincinnati, Inc. (collectively, "FiberNet") and the expansion of the Company's
intercity network. Monthly recurring revenue in the backlog at December
31, 1995 was approximately $4.2 million annualized, an approximately 45%
increase from the prior year. From December 31, 1994 to December 31, 1995, the
number of fiber miles in the Company's networks increased from 11,227 to
17,128; route miles increased from 378 to 504; and the number of customers
serviced by ICI (including interexchange customers) increased from 8,148 to
9,530.
 
  Operating expense in total increased by 184% from $16.9 million for 1994 to
$48.2 million in 1995, a $31.3 million increase. Approximately $20.5 million
of the increase was attributable to the inclusion of operating expenses
relating to the Company's interexchange long distance services. Approximately
$2.1 million of the increase was attributable to the inclusion of FiberNet's
operating expenses. The operating results of FiberNet have been included in
the consolidated results since March 1, 1995. The balance of the increase was
consistent with the significant expansion of the Company's owned and leased
networks and equipment sales to customers. As a result, the Company incurred a
net loss of $20.7 million for 1995, as compared to a net loss of $3.1 million
in 1994.
 
  Facilities administration and maintenance and line costs increased by 326%
from $5.4 million in 1994 to $23.0 million in 1995, a $17.6 million increase.
Approximately $13.3 million of the increase is due to inclusion of the
operating results of the Company's interexchange long distance services. In
addition, increases in maintenance expense due to network expansion, payroll
expense due to hiring additional engineering staff and cost of goods sold
related to equipment sold to customers contributed to the change.
 
  Selling, general, and administrative expense increased by 134% from $6.4
million in 1994 to $15.0 million in 1995, an $8.6 million increase.
Approximately $5.2 million of the increase is due to the inclusion of the
operating results of the Company's interexchange long distance services and
$.3 million is due to the inclusion of FiberNet's operating results. The
remaining change was primarily due to increases in sales commissions as a
result of increases in sales bookings, accounting, marketing and management
information systems staff, and increased property taxes relating to network
expansion and enhancements. In addition, the Company expended additional
resources by increasing the number and skill level of its sales and sales
support staff. Recovery of these additional expenditures typically is
recognized in future periods.

<PAGE>
 
  Depreciation and amortization expense increased by 99% from $5.1 million in
1994 to $10.2 million in 1995, an increase of $5.1 million. These increases
are directly related to the $34.9 million and $18.3 million of
telecommunications equipment additions (including capital leases) in 1995 and
1994, respectively, relating to ongoing network expansion and increases in the
amortization of intangibles associated with the acquisitions of Phone One and
FiberNet.
 
  Interest and other income increased 396% from $0.8 million in 1994 to $4.1
million in 1995, a $3.3 million increase, as a result of interest earned on
the cash available from the proceeds of the offering of the Senior Notes which
were received in June 1995.
 
  Interest expense increased by 1029% from $1.2 million in 1994 to $13.8
million in 1995, an increase of $12.6 million. The increase is primarily due
to the interest incurred on the Senior Notes.
 
  Extraordinary loss of $1.6 million was incurred which consisted of $1.2
million in prepayment penalties relating to certain indebtedness which was
repaid from the proceeds of the offering of the Senior Notes and the write off
of the unamortized deferred financing costs associated with the indebtedness
repaid.
 
  EBITDA decreased by $1.8 million or 74% from $2.5 million in 1994 to $0.6
million in 1995. As a percent of revenue, 1995 and 1994 EBITDA were
approximately 2% and 17%, respectively. This decline was the result of the
inclusion of a full year of revenues and expenses relating to interexchange
long distance services which have a lower operating margin than the Company's
other services, the incurrence of additional growth oriented expenses (such as
increases in sales and support staff and market development costs) prior to
realizing revenues associated with these expenditures and the Company's
introduction of switched access transport services to IXCs.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's operations have required substantial capital investment for
the purchase of telecommunications equipment and the design, construction and
development of the Company's networks. Capital expenditures for the Company
were $13.7 million, $30.0 million and $131.2 million in 1994, 1995 and 1996,
respectively, excluding capital leases and telecommunications equipment
acquired in connection with business acquisitions. The Company expects that it
will continue to have substantial capital requirements in connection with the
(i) expansion and improvement of the Company's existing networks, (ii) design,
construction and development of new networks, (iii) connection of additional
buildings and customers to the Company's networks, (iv) purchase of switches
necessary for local exchange services and expansion of interexchange services
and (v) development of the Company's enhanced data services.
 
  The Company has funded a substantial portion of these expenditures through
the public sale of debt and equity securities and, to a lesser extent,
privately placed debt. From inception through December 31, 1996, the Company
has raised approximately $212.6 million from the sale of Common Stock,
including Common Stock issued in connection with the acquisitions of FiberNet,
Phone One, EMI and UTT, and $324.6 million from the sale of the Existing
Senior Notes.
 
  The substantial capital investment required to build the Company's networks
has resulted in negative cash flow from operations after consideration of
investing activities over the last five year period. This negative cash flow
after investing activities is a result of the requirement to build a
substantial portion of the Company's network in anticipation of connecting
revenue generating customers. The Company expects to continue to produce
negative cash flow after investing activities for the next several years due
to expansion activities associated with the development of the Company's
networks. Until sufficient cash flow after investing activities is generated
from operation, the Company will be required to utilize its current and future
capital resources to meet its cash flow requirements, including the issuance
of additional debt and/or equity securities.
 
   In response to the new pro-competitive telecommunications environment (See
"Business--Government Regulation"), the Company has accelerated and expanded
its capital deployment plan to allow for an increased
 
                                      36
<PAGE>
 
level of demand-driven capital spending necessary to more rapidly exploit the
market opportunity in the local exchange market. The Company expects to expend
substantial amounts to upgrade its existing networks in order to switch
traffic within the local service area in those states where it is currently
permitted to provide such services. The Company is certified as a CLEC in 13
states and the District of Columbia, allowing the Company to provide local
exchange services in those markets, and has CLEC certification applications
pending in 22 states. In addition, the Company expects to expend capital
toward the further development of the Company's enhanced data service and
interchange service offerings.
 
  The Company currently estimates that it will require approximately $190
million to fund anticipated capital requirements during 1997, which it expects
to fund from its available cash, including the proceeds of the Private
Placement described in the next paragraph.
 
  On March 7, 1997, the Company sold 30,000 shares (aggregate liquidation
preference $300,000,000) of the Series A Preferred Stock in a private
placement transaction. Net proceeds to the Company amounted to approximately
$288,875,000. Dividends on the Series A Preferred Stock accumulate at a rate
of 13 1/2% of the aggregate liquidation preference thereof and are payable
quarterly, in arrears. Dividends are payable in cash or, at the Company's
option, by the issuance of additional shares of Series A Preferred Stock
having an aggregate liquidation preference equal to the amount of such
dividends. The Series A Preferred Stock is subject to mandatory redemption at
its liquidation preference of $10,000 per share, plus accumulated and unpaid
dividends on March 31, 2009. The Series A Preferred Stock will be redeemable
at the option of the Company at any time after March 31, 2002 at rates
commencing with 106.75%, declining to 100% on March 31, 2007.
 
  The Company may, at its option, exchange some or all shares of the Series A
Preferred Stock for the Company's 13 1/2% Senior Subordinated Debentures, due
2009 (the "Exchange Debentures"). The Exchange Debentures mature on March 31,
2009. Interest on the Exchange Debentures is payable semi-annually, and may be
paid in the form of additional Exchange Debentures at the Company's option.
Exchange Debentures will be redeemable by the Company at any time after March
31, 2002 at rates commencing with 106.75%, declining to 100% on March 31,
2007.
 
  The Company expects that its available cash, including proceeds from the
Private Placement, will be sufficient to fund its accelerated and expanded
capital deployment plan through 1998. The Company expects to require
additional financing to continue its capital deployment plan beyond 1998. The
Company may obtain additional funding through the sale of public or private
debt and/or equity securities or through securing a bank credit facility.
There can be no assurance as to the availability or the terms upon which such
financing might be available. Moreover, the Existing Senior Notes and the
Series A Preferred Stock impose certain restrictions upon the Company's
ability to incur additional indebtedness or issue additional preferred stock.
 
  The Company has from time to time held, and continues to hold, preliminary
discussions with (i) potential strategic investors (i.e., investors in the
same or a related business) who have expressed an interest in making an
investment in or acquiring the Company, (ii) potential joint venture partners
looking toward formation of strategic alliances that would expand the reach of
the Company's network or services without necessarily requiring an additional
investment in the Company and (iii) companies that represent potential
acquisition opportunities for the Company. There can be no assurance that any
agreement with any potential strategic investor, joint venture partner or
acquisition target will be reached nor does management believe that any such
agreement is necessary to successfully implement its strategic plans.
 
IMPACT OF INFLATION
 
  Inflation has not had a significant impact on the Company's operations over
the past three years.

GLOSSARY
 
  Access Charges--The charges paid by an interexchange carrier to a LEC for
the origination or termination of the IXC's customer's long distance calls.
 
  Access Line--A circuit that connects a telephone user (customer) to the
public switched telephone network. The access line usually connects to a
telephone at the customer's end.
 
  Access Node--A Nortel switching device, which extends the presence of the
DMS-500 switch to a remote site, such as an On-Net building. The Access Node
provides interfaces for line connections to the network, and provides
concentration of lines back to the DMS-500 switch.
 
  Access Trunk--A circuit that connects a telephone user's PBX or other
intelligent device to the public switched telephone network. An access trunk
is designed to carry more traffic than an access line, since it is accessible
to a number of users.
 
  ATM (Asynchronous Transfer Mode)--A modern information transfer standard
that allows packetized voice and data to share a transmission circuit. ATM
provides much greater efficiency than typical channelized transmission media.
 
  Bandwidth--The range of analog frequencies or the bit rate of digital
signals that can be supported by a circuit or device. The bandwidth of a
particular circuit is generally determined by the medium itself (wire, fiber
optic cable, etc.) and the device that transmits the signal to the
transmission medium (laser, audio amplifier, etc.)
 
  Bell System--The name given to the large, single entity that comprised what
are today AT&T and the RBOCs, including Bell Laboratories and other
subsidiaries.
 
  CAP (Competitive Access Provider)--A name for a category of local service
provider that appeared in the late 1980's, who competed with local telephone
companies by placing its own fiber optic cables in a city and sold various
private line telecommunications services in direct competition to the local
telephone company.
 
  CENTREX--A Central office based business telephone service that roughly
provides the user with the same services as a PBX, without the capital
investment of the PBX. Centrex services include station to station dialing (2
through 5 digits), customized long distance call handling, and user-input
authorization codes.
 
  CLEC (Competitive Local Exchange Carrier)--A category of telephone service
provider (carrier) that offers services similar to the former monopoly local
telephone company, as recently allowed by changes in telecommunications law
and regulation. A CLEC may also provide other types of telecommunications
services (long distance, etc.)
 
  CLEC (Certification)--Granted by a state public service commission or public
utility commission, this allows a telecommunications services provider the
legal standing to offer local exchange telephone services in direct
competition with the incumbent LEC and other CLECs. Such certifications are
granted on a state by state basis.
 
  CO (Central Office)--The switching center and/or central circuit terminating
facility of a local telephone company.
 
  Communications Act of 1934, The--The first major federal legislation that
established rules for broadcast and non-broadcast communications, both
wireless and wired telephony.
 
  Connected Building--A building that is connected to a carrier's network via
a non-switched circuit that is managed and monitored by that carrier.
 
  Dedicated Access--A circuit that connects a customer to a carrier's network,
not shared amongst multiple customers.
 
                                      42

  Diverse Routing--A network topology that provides reliability by providing
two distinct physical routes for network transmission path (fiber optic or
copper cables) with the ability to quickly "switch" traffic from one route to
the other, should one of the routes be rendered inoperable.
 
  DMS-500--A telephone switch manufactured by Nortel, that provides both local
exchange switching (also known as a "class 5" switch) and a long distance
switch (also known as a "class 4" switch) in a single device.
 
  EBITDA--Earnings Before Interest, Tax, Depreciation, and Amortization - a
financial measure of cash flow
 
  Enhanced Data Services--Data networking services provided on a sophisticated,
software managed transport and switching network, such as a frame relay or ATM
data network.
 
  FCC (Federal Communications Commission)--The US Government organization
charged with the oversight of all public communications media.
 
  Feature Group Circuit--A telecommunications channel that connects a LEC
telephone switch with an IXC telephone switch, for the purpose of passing long
distance calls between the two carriers' networks. Calls placed by dialing "1+"
are routed over these circuits.
 
  Frame Relay--A wide area information transport technology that organizes data
into units called frames, with variable bit length, designed to move
information that is "bursty" in nature.
 
  ICP (Integrated Communications Provider)--A telecommunications carrier that
provides packaged or integrated services from among a broad range of
categories, including local exchange service, long distance service, enhanced
data service, cable TV service, and other communications services.
 
  ILEC (Incumbent Local Exchange Carrier)--The local exchange carrier that was
the monopoly carrier, prior to the opening of local exchange services to
competition.
 
  ILEC Collocation--A location serving as the interface point for a CLEC's
network at the point of interconnection to the ILEC. Subcollocation can be 1)
physical, in which the CLEC "builds" a fiber optic network extension into the
ILEC central office, or 2) virtual, in which the ILEC leases a facility,
similar to that which it might build, to affect a presence in the ILEC central
office.
 
  Interconnection (co-carrier) Agreement--A contract between an ILEC and a CLEC
for the interconnection of the two's networks, for the purpose of mutual
passing of traffic between the networks, allowing customers of one of the
networks to call users served by the other network. These agreements set out
the financial and operational aspects of such interconnection.
 
  Interexchange Services--Telecommunications services that are provided between
two exchange areas, generally meaning between two cities. These services can be
either voice or data.
 
  Interim Number Portability--A temporary technique that allows local exchange
service customers of an ILEC to keep their existing telephone number, while
moving their service to a CLEC. Their interim technique uses a central office
feature called remote call forwarding. The permanent solution to number
portability is to implemented over the next few years.
 
  ISDN (Integrated Services Digital Network)--a modern telephone technology
that combines voice and data switching in an efficient manner.
 
  ISP (Internet Service Provider)--a recently created category of
telecommunications service provider who provides access to the Internet,
normally for dial access customers, by sharing communications lines and
equipment.
 
  IXC (Interexchange Carrier)--A provider of telecommunications services that
extend between exchanges, or cities. Also called long distance carrier.

by carriers in both local and long distance telecommunications networks to
provide efficient, highly reliable communications channels.
 
  Special Access Services--Private, non-switched connections between an IXC and
a customer, for the purpose of connecting the customer's long distance calls to
the IXC's network, without having to pay the LEC's access charges.
 
  Systems Integration--The provision of specialized skills and equipment to
meet specific customer needs.
 
  VSAT (Very Small Aperture Terminal)--A satellite communication system that
comprises small diameter (approximately 1 meter in diameter) antennae and
electronics to establish a communications terminal, use mostly for data. VSAT
networks compete with other, landline based networks such as private lines and

Board of Directors
Intermedia Communications Inc.
 
  We have audited the accompanying consolidated balance sheets of Intermedia
Communications Inc. as of December 31, 1995 and 1996, and the related
consolidated statements of operations, stockholders' equity, and cash flows
for each of the three years in the period ended December 31, 1996. Our audits
also included the financial statement schedule listed in the index at Item

Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Intermedia Communications Inc. at December 31, 1995 and 1996, and the
consolidated results of its operations and its cash flows for each of the

generally accepted accounting principles. Also, in our opinion, the related
financial statement schedule, when considered in relation to the basic
financial statements taken as a whole, present fairly in all material respects

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Business
 
  Intermedia Communications Inc. (ICI or the Company), formerly Intermedia
Communications of Florida, Inc. through May 29, 1996, is an integrated
communications services provider offering a full suite of local, long-distance
and enhanced data services to business and government end users. Services
include data and video telecommunications services, frame relay, Internet
access services, local exchange services, long-distance services and
telecommunications equipment. The Company offers its full product package of
telecommunications services to customers in 15 metropolitan statistical areas
in the eastern half of the United States.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of Intermedia
Communications Inc. and its subsidiaries, all of which are wholly owned. All
significant intercompany transactions and balances have been eliminated in
consolidation.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
 Cash Equivalents
 
  The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
 Short-Term Investments
 
  Short-term investments consist of certificates of deposit with maturities of
more than three months when purchased and are stated at cost.
 
 Restricted Investments
 
  Restricted investments consist of U.S. Treasury Notes which are restricted
for the repayment of interest on certain debt and are stated at amortized
cost. Management designated these investments as held-to-maturity securities
in accordance with the provisions of Statement of Financial Accounting
Standards No.115, Accounting for Certain Investments in Debt and Equity
Securities.
 
 Telecommunications Equipment
 
  Telecommunications equipment is stated at cost. Depreciation expense is
calculated using the straight-line method over the estimated useful lives of
the assets as follows:
 
<TABLE>
   <S>                                                                <C>
   Telecommunications equipment...................................... 3--7 years
   Fiber optic cable.................................................   20 years
   Furniture and fixtures............................................ 5--7 years
</TABLE>

<PAGE>
 
                        INTERMEDIA COMMUNICATIONS INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Leasehold improvements are amortized using the straight-line method over the
shorter of the term of the lease or the estimated useful life of the
improvements.
 
 Intangible Assets
 
  Intangible assets are stated at cost and include purchased customer lists,
deferred debt issuance costs, and goodwill. Customer lists are amortized using
the straight-line method over their estimated useful lives of eight years.
Goodwill is amortized using the straight-line method over periods of eight to
forty years.
 
  As more fully discussed in Note 2, during December 1996, the Company
acquired Universal Telcom, Inc. and NetSolve, Inc. in transactions accounted
for using the purchase method. The excess of the respective purchase prices
over the fair value of tangible net assets acquired have been preliminarily
classified in the accompanying consolidated balance sheets as intangible
assets. The final allocation to identifiable intangible assets is currently
underway by management. The preliminary intangible assets not allocated to
identifiable tangible and intangible assets will be recorded as goodwill.
 
  Deferred debt issuance costs relate to the issuance of debt and are
amortized using the effective interest method over the term of the debt
agreements. The related amortization is included as a component of interest
expense in the accompanying consolidated statements of operations.
 
 Revenue Recognition
 
  The Company recognizes revenue in the period the service is provided or the
goods are shipped for equipment product sales. Unbilled revenues represent
revenues earned for telecommunications services provided which will be billed
in the succeeding month and totaled $636,257 and $2,403,584 and as of December
31, 1995 and 1996, respectively. Unbilled revenues are included as a component
of accounts receivable in the accompanying consolidated balance sheets. The
Company invoices customers one month in advance for recurring services
resulting in advance billings at December 31, 1995 and 1996 of $1,747,100 and
$3,137,000 respectively.
 
 Income Taxes
 
  The Company has applied the provisions of Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes, which requires an asset and
liability approach in accounting for income taxes for all years presented.
Deferred income taxes are provided for in the consolidated financial
statements and principally relate to net operating losses and basis
differences for customer lists and telecommunications equipment.
 
 Loss Per Share
 
  Loss per share is based on the weighted average shares outstanding. Common
stock equivalents are not considered in the Company's calculation of loss per
share as all are antidilutive and would have no impact on the results.
 
 Concentrations of Credit Risk
 
  The Company's financial instruments that are exposed to concentrations of
credit risk, as defined by Statement of Financial Accounting Standards No.
105, Disclosure of Information About Financial Instruments with Off-Balance-
Sheet Risk and Financial Instruments with Concentrations of Credit Risk, are
primarily cash and cash equivalents and accounts receivable.

                        INTERMEDIA COMMUNICATIONS INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

  The Company places its cash and temporary cash investments with high-quality
institutions. As of December 31, 1996, cash equivalents totaling approximately
$227,000,000 were held by a single financial institution. Such amounts were
collateralized by government-backed securities.
 
  Accounts receivable are due from residential and commercial
telecommunications customers. Credit is extended based on evaluation of the
customer's financial condition and generally collateral is not required.
Anticipated credit losses are provided for in the consolidated financial
statements and have been within management's expectations.
 
STOCK-BASED COMPENSATION
 
  The Company accounts for stock-based compensation in accordance with APB No.
25, Accounting for Stock Issued to Employees, and, in cases where exercise
prices equal or exceed fair market value, recognizes no compensation expense
for the stock option grants. In cases where exercise prices are less than fair
value, compensation is recognized over the period of performance or the
vesting period.
 
  In October 1995, the FASB issued Statement of Financial Accounting Standards
No. 123, Accounting and Disclosure of Stock-Based Compensation, (Statement
123) which encourages, but does not require, companies to recognize stock
awards based on their fair value at the date of grant. Unaudited pro forma
financial information, assuming that the Company had adopted the measurement
standards of Statement 123, is included in Note 7.
 
RECLASSIFICATIONS
 
  Certain prior year investment accounts have been reclassified as restricted
in order to conform with the 1996 presentation.
 
2. BUSINESS ACQUISITIONS
 
  During December 1994, the Company acquired the common stock of Phone One,
Inc. in exchange for 740,000 shares of common stock of the Company, valued at
approximately $8,800,000. The acquisition was accounted for by the purchase
method of accounting, with the purchase price allocated based on fair values
of assets acquired, principally customer lists, and liabilities assumed. The
operating results of Phone One, Inc. are included in the Company's
consolidated financial statements from the date of acquisition.
 
  During February 1995, the Company acquired FiberNet in exchange for 683,583
shares of the Company's common stock, valued at approximately $7,800,000, the
assumption of approximately $5,000,000 in liabilities and a note payable of
$1,200,000 which was paid on July 17, 1995. The acquisition was accounted for
by the purchase method of accounting with the purchase price allocated based
on fair values of assets acquired and liabilities assumed. The excess of the
purchase price over the fair values of the net assets amounted to $11,000,000
and is being amortized over 20 years. The operating results of FiberNet are
included in the Company's consolidated financial statements since March 1,
1995 since the operating results from the date of acquisition were deemed to
be immaterial.
 
  During June 1996, the Company acquired the Telecommunications Division of
EMI Communications Corporation (EMI) in exchange for 937,500 shares of the
Company's common stock, valued at approximately $16,900,000. The acquisition
was accounted for by the purchase method of accounting, with the purchase
price allocated to the fair values of assets acquired, principally
telecommunications equipment. The operating results of EMI are included in the
Company's consolidated financial statements from the date of acquisition.

  During December 1996, the Company acquired, in two separate transactions,
certain assets and the related businesses of Universal Telcom, Inc. (UTT) and
NetSolve, Incorporated (NetSolve). The purchase price for UTT included 31,380
shares of the Company's common stock, valued at approximately $900,000, and
the assumption of approximately $2,000,000 of UTT's liabilities. NetSolve was
purchased for cash of $12,800,000. The operations of UTT and NetSolve are
included in the Company's consolidated financial statements from December 1,
1996, at which date the Company exercised control. The acquisitions are
accounted for by the purchase method, with the purchase price to be allocated
to the assets acquired based upon fair values. The allocation of the purchase
price to both UTT and NetSolve is tentative pending completion of the
valuations of certain identifiable intangibles.
 
  The following unaudited pro forma results of operations for the years ended
December 31 assume the acquisitions of FiberNet, EMI, UTT and NetSolve had
occurred at the beginning of the periods presented, and do not purport to be
indicative of the results that actually would have occurred if the
acquisitions had been made as of those dates or of results which may occur in
the future.

</TABLE>
 
  The following methods and assumptions are used in estimating fair values for
financial instruments:
 
  Cash and cash equivalents: The carrying amount reported in the consolidated
balance sheets for cash and cash equivalents approximates its fair value.
 
  Investments: As of December 31, 1996, these investments are classified as
held-to-maturity, in accordance with SFAS 115, Accounting for Certain
Investments in Debt and Equity Securities. The fair value of these investments
is estimated from quoted market prices.
 
  Accounts receivable and accounts payable: The carrying amounts reported in
the consolidated balance sheets for accounts receivable and accounts payable
approximate their fair value.
 
  Long-term and short-term debt: The estimated fair value of the Company's
borrowing is based on negotiated trades for the securities as provided by the
Company's investment banker or by using discounted cash flows at the Company's
incremental borrowing rate.
 
7. STOCKHOLDERS' EQUITY
 
  Stock Options: The Company has a 1992 Stock Option Plan and a 1996 Long-Term
Incentive Plan (the Plans) under which options to acquire an aggregate of
1,346,000 shares and 1,500,000 shares, respectively, of common stock may be
granted to employees, officers, directors and consultants of the Company. The
Plans authorize the Board of Directors (the Board) to issue incentive stock
options (ISOs), as defined in Section 422A(b) of the Internal Revenue Code,
and stock options that do not conform to the requirements of that Code section
(Non-ISOs). The Board has discretionary authority to determine the types of
stock options to be granted, the persons among those eligible to whom options
will be granted, the number of shares to be subject to such options, and the
terms of the stock option agreements. Options may be exercised in the manner
and at such times as fixed by the Board, but may not be exercised after the
tenth anniversary of the grant of such options.

  The Board of Directors has reserved 674,142 shares of common stock in
connection with stock warrants, and 2,462,341 shares of common stock that may
be issued to employees, officers, directors, and consultants of the Company
pursuant to stock options as may be determined by the Board of Directors.
 
  Pro forma information regarding net income and earnings per share is
required by Statement 123, which also requires that the information be
determined as if the Company had accounted for its employee stock options
granted subsequent to December 31, 1994 under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1995 and 1996: risk-free interest rates of 6.2%; a dividend
yield of zero; volatility factors of the expected market price of the
Company's common stock based on historical trends; and a weighted-average
expected life of the options of five years.
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.
 
  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The
Company's pro forma information follows:

  Stock Award Plans: During 1996, the Company entered into restricted share
agreements with three executive officers that provide stock award incentives.
Pursuant to the agreements, up to an aggregate of 255,000 restricted shares of

certain stock price milestones ranging from $20 to $40. Shares awarded under
these arrangements vest over a period of five years following the award.

</TABLE>
 
  As further discussed in Note 5, the Company issued warrants expiring in 2000
to acquire 350,400 shares of common stock in connection with the issuance of
the Senior Notes. The Company also has warrants outstanding that had been
issued for consulting services.
 
  Shareholder Rights Plan: On March 7, 1996, the Board of Directors adopted a
Shareholder Rights Plan and declared a dividend of one common stock Purchase
Right (a Right) for each outstanding share of common stock to shareholders of
record on March 18, 1996. Such Rights only become exercisable, or transferable
apart from the common stock, ten business days after a person or group (an
Acquiring Person) acquires beneficial ownership of, or commences a tender or
exchange offer for, 15% or more of the Company's common stock.
 
  Each Right then may be exercised to acquire 1/1000th of a share of the
Company's Series C preferred stock at an exercise price of $85. Thereafter,
upon the occurrence of certain events, the Rights entitle holders other than
the Acquiring Person to acquire the existing Company's preferred stock or
common stock of the surviving company having a value of twice the exercise
price of the Rights.
 
  The Rights may be redeemed by the Company at a redemption price of $.01 per
Right at any time until the 10th business day following public announcement
that a 15% position has been acquired or ten business days after commencement
of a tender or exchange offer.
 
  Authorized Shares: On May 24, 1996, the Board of Directors approved an
increase in the number of shares of authorized common stock from 20,000,000 to
50,000,000.

10. EMPLOYEE BENEFIT PLAN
 
  The Company has established a 401(k) profit-sharing plan. Employees 21 years
or older with one year of service are eligible to participate in the plan.
Participants may elect to contribute, on a tax-deferred basis, up to 15% of
their compensation, not to exceed $9,500 in 1996. The Company will match one-
half of a participant's contribution, up to a maximum of 3% of the
participant's compensation. The Company's matching contribution fully vests
after five years of service. The Company's contributions to the plan were
approximately $58,000, $85,000 and $77,000 in 1994, 1995 and 1996,
respectively.
 
11. OPERATING LEASES
 
  The Company leases rights-of-way and cable conduit space, fiber optic cable,
terminal facility space, and office space. The leases generally contain
renewal options which range from one year to fifteen years, with certain
rights-of-way and cable conduit space being renewable indefinitely after the
minimum lease term subject to cancellation notice by either party to the
lease. Lease payments in some cases may be adjusted for related revenues,
increases in property taxes, operating costs of the lessor, and increases in
the Consumer Price Index. Lease expense was $908,000, $1,466,000 and
$4,795,000, and for 1994, 1995, and 1996, respectively.
 
  Future minimum lease payments under noncancelable operating leases with

12. CONTINGENCIES
 
  On May 3, 1995, the Company asserted a claim for indemnification against the
former shareholder of Phone One, Inc. (the Former Shareholder) for
approximately $1 million on account of various breaches of representations and
warranties made by the Former Shareholder to the Company in the agreement for
the acquisition of Phone One, Inc. (the Phone One Acquisition Agreement). The
Former Shareholder has objected to the indemnification claim, which is subject
to arbitration under the Phone One Acquisition Agreement. On May 24, 1995, the
Former Shareholder advised the Company that it has filed a complaint against
the Company in the Florida circuit court for Dade County seeking rescission of
the Phone One, Inc. acquisition and damages for breach of contract in excess
of $3 million. Pursuant to the mandatory arbitration requirements of the Phone
One Acquisition Agreement, in July 1995, the Company filed a demand for
arbitration, and the action was stayed in the circuit court. The parties
negotiated a settlement proposal, and on August 27, 1996, the dispute was
settled and mutual general releases exchanged by which the Company delivered
22,357 of the holdback shares, pursuant to the terms of the Phone One
Acquisition Agreement. On September 3, 1996, the action in circuit court was
dismissed with prejudice.
 
  The Company is not a party to any other pending legal proceedings except for
various claims and lawsuits arising in the normal course of business. The
Company does not believe that these normal course of business claims or
lawsuits will have a material effect on the Company's financial condition,
results of operations or cash flows.

13. SUBSEQUENT EVENT
 
  On March 7, 1997, the Company sold 30,000 shares (aggregate liquidation
preference $300,000,000) of its 13 1/2% Series A Redeemable Exchangeable
Preferred Stock, due 2009, (the "Preferred Stock") in a private placement
transaction. Net proceeds to the Company amounted to approximately
$288,875,000. Dividends on the Preferred Stock accumulate at a rate of 13 1/2%
of the aggregate liquidation preference and are payable quarterly, in arrears.
Dividends are payable in cash or, at the Company's option, by the issuance of
additional shares of Preferred Stock having an aggregate liquidation
preference equal to the amount of such dividends. The Preferred Stock is
subject to mandatory redemption at its liquidation preference of $10,000 per
share, plus accumulated and unpaid dividends on March 31, 2009. The Preferred
Stock will be redeemable at the option of the Company at any time after March
31, 2002 at rates commencing with 106.75%, declining to 100% on March 31,

          The undersigned DOES HEREBY CERTIFY as follows:

          I.   The name of the Corporation is INTERMEDIA COMMUNICATIONS OF
FLORIDA, INC. ( the "Corporation").

          II.  The date of filing of the Corporation's original Certificate of

          III. Upon the filing of this Restated Certificate of Incorporation,
each 2.8 issued and outstanding shares of Common Stock, $.01 par value per
share, of the Corporation  ("Old Common Stock"), shall automatically, without
any further action by the holder thereof or by the Corporation, be reclassified
and deemed to be one validly issued, fully paid and nonassessable share of
Common Stock, $.01 par value per share, of the Corporation ("New Common Stock").
No certificates or scrip representing fractional shares of New Common Stock
shall be issued by reason hereof.  If a fractional share would be issuable to
any one holder of Old Common Stock pursuant hereto, then the number of shares
into which such Old Common Stock will be reclassified pursuant hereto 
<PAGE>
 
will be rounded to the next highest number of whole shares of New Common Stock.
Each certificate for 2.8 shares of Old Common Stock prior to the filing of this
Restated Certificate of Incorporation will be deemed upon the filing hereof to
represent a certificate for one share of New Common Stock (subject to the
treatment of fractional interests described above).

          IV.  Concurrently with the filing of this Restated Certificate of
Incorporation, each outstanding share of the Corporation's Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock, $1.00 par value

dividends thereon), at the election of the Corporation, into fully paid and
nonassessable shares of New Common Stock, all pursuant to the terms and
conditions of such Preferred Stock.

          V.  The Certificate of Incorporation, as heretofore amended, of the
Corporation ( the "Certificate of Incorporation") is amended hereby as follows:

(a)  Article FOURTH is amended to (i) increase the number of shares of capital
     stock which the Corporation shall have authority to issue, (ii) eliminate
     the designations of the Series A, B, C, and D Preferred Stock of the
     Corporation (the "Series Preferred Stock") and all powers, preferences,
     privileges, voting, dividend and other special or relative rights and
     qualifications of the Series 

                                      -2-

     Preferred Stock, including the related prohibition on reissuance of such
     Series Preferred Stock, and (iii) eliminate the parenthetical reference in
     A(2) of Article FOURTH to written actions by stockholders in lieu of
     meetings;

(b)  Articles FIFTH and SIXTH are hereby deleted in their entirety, in part, to
     eliminate the supermajority voting requirement to effect a merger or
     consolidation;

(c)  new Articles FIFTH and SIXTH are inserted, among other things, to (i)
     establish the number of directors of the Corporation, with the number of
     directors to be fixed from time to time by resolution of the Board of
     Directors of the Corporation (the "Board"), (ii) reorganize the Board into
     three classes with staggered terms, and (iii) eliminate the ability of
     stockholders to take action by written consent; and

(d)  Article NINTH is amended to conform it to the changes stated hereinabove.

the Board and authorized by the affirmative vote of the stockholders pursuant to

     I, David C. Ruberg, President and Chief Executive Officer of Intermedia

General Corporation Law of the State of Delaware (the "Corporation"), DO HEREBY
                                                       -----------
CERTIFY:

     that, pursuant to authority conferred upon the Board of Directors of the
Corporation by its Certificate of Incorporation (the "Certificate"), and,
                                                      ------------
pursuant to the provisions of Section 151 of the General Corporation Law of the
State of Delaware, said Board of Directors, at a duly called meeting held on
March 7, 1996, at which a quorum was present and acted throughout, adopted the
following resolutions, which resolutions remain in full force and effect on the
date hereof creating a series of 200,000 shares of Preferred Stock having a par
value of $1.00 per share, designated as Series A Preferred Stock (the "Series A
                                                                       -------- 
Preferred Stock") out of the class of 500,000 shares of preferred stock of the
- ---------------
par value of $1.00 per share (the "Preferred Stock"):
                                   ---------------

     RESOLVED, that pursuant to the authority vested in the Board of Directors
in accordance with the provisions of the Certificate, the Board of Directors
does hereby create, authorize and provide for the issuance of the Series A
Preferred Stock  having the voting powers, designation, relative, participating,
optional and other special rights, preferences, and qualifications, limitations
and restrictions thereof that are set forth as follows:

     Section 1.  Designation and Amount.  The shares of such series shall be
                 ----------------------
designated as "Series A Preferred Stock" and the number of shares constituting
               ------------------------
such series shall be 200,000.
<PAGE>
 
     Section 2.  Dividends and Distributions.
                 ----------------------------

     (A)  Subject to the prior and superior rights of the holders of any shares
of any other series of Preferred Stock or any other shares of preferred stock of
the Corporation ranking prior and superior to the shares of Series A Preferred
Stock with respect to dividends, each holder of one one-hundredth (1/100) of a
share (a "Unit") of Series A Preferred Stock shall be entitled to receive, when,
          ----
as and if declared by the Board of Directors out of funds legally available for
that purpose, (i)  quarterly dividends payable in cash on the last day of March,
June, September and December in each year (each such date being a "Quarterly
                                                                   ---------
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
- ---------------------
after the first issuance of such Unit of Series A Preferred Stock, in an amount
per Unit (rounded to the nearest cent) equal to the greater of (a) $.01 or (b)
subject to the provision for adjustment hereinafter set forth, the aggregate per
share amount of all cash dividends declared on shares of the Common Stock since
the immediately preceding Quarterly Dividend Payment Date, or, with respect to
the first Quarterly Dividend Payment Date, since the first issuance of a Unit of
Series A Preferred Stock, and (ii) subject to the provision for adjustment
hereinafter set forth, quarterly distributions (payable in kind) on each
Quarterly Dividend Payment Date in an amount per Unit equal to the aggregate per
share amount of all non-cash dividends or other distributions (other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock, by reclassification or otherwise) declared on shares of
Common Stock since the immediately preceding quarterly Dividend Payment Date, or
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of a Unit of Series A Preferred Stock.  In the event that the
Corporation shall at any time after March 18, 1996 (the "Rights Declaration")
                                                         ------------------
(i) declare any dividend on outstanding shares of Common Stock payable in shares
of Common Stock, (ii)  subdivide outstanding shares of Common Stock or (iii)
combine outstanding shares of Common Stock into a smaller number of shares, then
in each such case the amount to which the holder of a Unit of Series A Preferred
Stock was entitled immediately prior to such event pursuant to the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which shall be the number of shares of Common Stock that are
outstanding immediately after such event and the denominator of which shall be
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     (B) The Corporation shall declare a dividend or distribution on Units of
Series A Preferred Stock as 


                                       2
<PAGE>
 
provided in paragraph (A) above immediately after it declares a dividend or
distribution on the shares of Common Stock (other than a dividend payable in
shares of Common Stock); provided, however, that, in the event no dividend or
                         --------  -------
distribution shall have been declared on the Common Stock during the period
between any Quarterly Dividend Payment Date and the next Quarterly Dividend
Payment Date, a dividend of $.01 per Unit on the Series A Preferred Stock shall
nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

     (C) Dividends shall begin to accrue and shall be cumulative on each
outstanding Unit of Series A Preferred Stock from the quarterly Dividend Payment
Date next preceding the date of issuance of such Unit of Series A Preferred
Stock, unless the date of issuance of such Unit is prior to the record date for
the first Quarterly Dividend Payment Date, in which case, dividends on such Unit
shall begin to accrue from the date of issuance of such Unit, or unless the date
of issuance is a Quarterly Dividend Payment Date or is a date after the record
date for the determination of holders of Units of Series A Preferred Stock
entitled to receive a quarterly dividend and before such Quarterly Dividend
Payment Date, in either of which events such dividends shall begin to accrue and
be cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
dividends shall not bear interest.  Dividends paid on Units of Series A
Preferred Stock in an amount less than the aggregate amount of all such
dividends at the time accrued and payable on such Units shall be allocated pro
rata on a unit-by-unit basis among all Units of Series A Preferred Stock at the
time outstanding.  The Board of Directors may fix a record date for the
determination of holders of Units of Series A Preferred Stock entitled to
receive payment of a dividend or distribution declared thereon, which record
date shall be no more than 30 days prior to the date fixed for the payment
thereof.

     Section 3.  Voting Rights.  The holders of Units of Series A Preferred
                 -------------
Stock shall have the following voting rights:

     (A) Subject to the provision for adjustment hereinafter set forth, each
Unit of Series A Preferred Stock shall entitle the holder thereof to one vote on
all matters submitted to a vote of the stockholders of the Corporation.  In the
event the Corporation shall at any time after the Rights Declaration Date (i)
declare any dividend on outstanding shares of Common Stock payable in shares of
Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine
the outstanding shares of Common

                                       3
<PAGE>
 
Stock into a smaller number of shares, then in each such case the number of
votes per Unit to which holders of Units of Series A Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction the numerator of which shall be the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which shall be the number of shares of Common Stock that were outstanding
immediately prior to such event.

     (B) Except as otherwise provided herein or by law, the holders of Units of
Series A Preferred Stock and the holders of shares of Common Stock shall vote
together as one class on all matters submitted to a vote of stockholders of the
Corporation.

     (C) (i)   If at any time dividends on any Units of Series A Preferred Stock
shall be in arrears in an amount equal to six quarterly dividends thereon, then
during the period (a "default period") from the occurrence of such event until
                      --------------
such time as all accrued and unpaid dividends for all previous quarterly
dividend periods and for the current quarterly dividend period on all Units of
Series A Preferred Stock then outstanding shall have been declared and paid or
set apart for payment, all holders of Units of Series A Preferred Stock, voting
separately as a class, shall have the right to elect two Directors, provided
that if the Directors are divided into classes, the holders of Units of Series A
Preferred Stock shall not elect more than one Director to any one class.

     (ii) During any default period, such voting rights of the holders of Units
of Series A Preferred Stock may be exercised initially at a special meeting
called pursuant to subparagraph (iii) of this Section 3(C) or at any annual
meeting of stockholders, and thereafter at annual meetings of stockholders,
provided that neither such voting rights nor any right of the holders of Units
of Series A Preferred Stock to increase, in certain cases, the authorized number
of Directors may be exercised at any meeting unless one-third of the outstanding
Units of Preferred Stock shall be present at such meeting in person or by proxy.
The absence of a quorum of the holders of Common Stock shall not affect the
exercise by the holders of Units of Series A Preferred Stock of such rights. At
any meeting at which the holders of Units of Series A Preferred Stock shall
exercise such voting rights initially during an existing default period, they
shall have the right, voting separately as a class, to elect Directors to fill
up to two vacancies in the Board of Directors, if any such vacancies may then
exist, or, if such right is exercised at an annual meeting, to elect two

                                       4
<PAGE>
 
Directors.  If the number which may be so elected at any special meeting does
not amount to the required number, the holders of the Series A Preferred Stock
shall have the right to make such increase in the number of Directors as shall
be necessary to permit the election by them of the required number.  After the
holders of Units of Series A Preferred Stock shall have exercised their right to
elect Directors during any default period, the number of Directors shall not be
increased or decreased except as approved by a vote of the holders of Units of
Series A Preferred Stock as herein provided or pursuant to the rights of any
equity securities ranking senior to the Series A Preferred Stock.

     (iii)  Unless the holders of Series A Preferred Stock shall, during an
existing default period, have previously exercised their right to elect
Directors, the Board of Directors may order, or any stockholder or stockholders
owning in the aggregate not less than 25% of the total number of the Units of
Series A Preferred Stock outstanding may request, the calling of a special
meeting of the holders of Units of Series A Preferred Stock, which meeting shall
thereupon be called by the Secretary of the Corporation.  Notice of such meeting
and of any annual meeting at which holders of Units of Series A Preferred Stock
are entitled to vote pursuant to this paragraph (C)(iii) shall be give to each
holder of record of Units of Series A Preferred Stock by mailing a copy of such
notice to him at his last address as the same appears on the books of the
Corporation.  Such meeting shall be called for a time not earlier than 20 days
and not later than 60 days after such order or request or in default of the
calling of such meeting within 60 days after such order or request, such meeting
may be called on similar notice by any stockholder or stockholders owning in the
aggregate not less than 25% of the total number of outstanding Units of Series A
Preferred Stock.  Notwithstanding the provisions of this paragraph (C) (iii), no
such special meeting shall be called during the 60 days immediately preceding
the date fixed for the next annual meeting of the stockholders.

     (iv) During any default period, the holders of shares of Common Stock and
Units of Series A Preferred Stock, and other classes or series of stock of the
Corporation, if applicable, shall continue to be entitled to elect all the
Directors until holders of the Units of Series A Preferred Stock shall have
exercised their right to elect two Directors voting as a separate class, after
the exercise of which right (x) the Directors so elected by the holders of Units
of Series A Preferred Stock shall continue in office until their successors
shall have been elected by such holders or until the expiration of the default
period, and


                                       5
<PAGE>
 
(y) any vacancy in the Board of Directors may (except as provided in paragraph
(C) (ii) of this Section 3) be filled by vote of a majority of the remaining
Directors theretofore elected by the holders of the class of capital stock which
elected the Director whose office shall have become vacant.  References in this
paragraph (C) to Directors elected by the holders of a particular class of
capital stock shall include Directors elected by such Directors to fill
vacancies as provided in clause (y) of the foregoing sentence.

     (v)   Immediately upon the expiration of a default period, (x) the right of
the holders of Units of Series A Preferred Stock as a separate class to elect
Directors shall cease, (y) the term of an Directors elected by the holders of
Units of Series A Preferred Stock as a separate class shall terminate, and (z)
the number of directors shall be such number as may be provided for in the
Certificate or by-laws irrespective of any increase made pursuant to the
provisions of paragraph (C) (ii) of this Section 3 (such number being subject,
however, to change thereafter in any manner provided by law or in the
Certificate or by-laws). Any vacancies in the Board of Directors effected by the
provisions of clauses (y) and (z) in the preceding sentence may be filled by a
majority of the remaining Directors.

     (vi) The provisions of this paragraph (C) shall govern the election of
Directors by holders of Units of Preferred Stock during any default period
notwithstanding any provisions of the Certificate to the contrary, including,
without limitation, the provisions of Article FIFTH of the Certificate.

     (D) Except as set forth herein, holders of Units of Series A Preferred
Stock shall have no special voting rights and their consents shall not be
required (except to the extent they are entitled to vote with holders of shares
of Common Stock as set forth herein) for taking any corporate action.

     Section 4.  Certain Restrictions.
                 ---------------------

     (A) Whenever quarterly dividends or other dividends or distributions
payable on Units of Series A Preferred Stock as provided in Section 2 are in
arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on outstanding Units of Series A
Preferred Stock shall have been paid in full, the Corporation shall not:

                                       6
<PAGE>
 
              (i) declare or pay dividends on, make any other distributions on,
       or redeem or purchase or otherwise acquire for consideration any shares
       of junior stock;

              (ii) declare or pay dividends on or make any other distributions
       on any shares of parity stock, except dividends paid ratably on Units of
       Series A Preferred Stock and shares of all such parity stock on which
       dividends are payable or in arrears in proportion to the total amounts to
       which the holders of such Units and all such shares are then entitled;

              (iii)  redeem or purchase or otherwise acquire for consideration
       shares of any parity stock, provided, however, that the Corporation may
                                   -----------------
       at any time redeem, purchase or otherwise acquire shares of any such
       parity stock in exchange for shares of any junior stock;

              (iv) purchase or otherwise acquire for consideration any Units of
       Series A Preferred Stock, except in accordance with a purchase offer made
       in writing or by publication (as determined by the Board of Directors) to
       all holders of such Units.

     (B) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of  this Section
4, purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Reaquired Shares.  Any Units of Series A Preferred Stock
                 ----------------
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof.  All such
Units shall, upon their cancellation, become authorized but unissued Units of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

     Section 6.  Liquidation, Dissolution or Winding Up.
                 ---------------------------------------

     (A) Upon any voluntary or involuntary liquidation, dissolution or winding
up  of the Corporation, no distribution shall be made (i)  to the holders of
shares of junior stock unless the holders of Units of Series A Preferred Stock
shall have received, subject to adjustment as hereinafter provided in paragraph
(B), the greater of either (a) $85.00 per Unit plus an amount equal to accrued
and unpaid dividends and distributions thereon, whether or

                                       7
<PAGE>
 
not earned or declared, to the date of such payment, or (b) the amount equal to
the aggregate per share amount to be distributed to holders of shares of Common
Stock, or (ii) to the holders of shares of shares of parity stock, unless
simultaneously therewith distributions are made ratably on Units of Series A
Preferred Stock and all other shares of such parity stock in proportion to the
total amounts to which the holders of Units of Series A Preferred Stock are
entitled under clause (i) (a) of this sentence and to which the holders of
shares of such parity stock are entitled, in each case upon such liquidation,
dissolution or winding up.

     (B) In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on outstanding shares of Common Stock
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common
Stock, or (iii) combine outstanding shares of Common Stock into a smaller number
of shares, then in each such case the aggregate amount to which holders of Units
of Series A Preferred Stock were entitled immediately prior to such event
pursuant to clause (i) (b) of paragraph (A) of this Section 6 shall be adjusted
by multiplying such amount by a fraction the numerator of which shall be the
number of shares of Common Stock that are outstanding immediately after such
event and the denominator of which shall be the number of shares of Common Stock
that were outstanding immediately prior to such event.

     Section 7.  Consolidation, Merger, etc.  In case the Corporation shall
                 --------------------------
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or converted into other stock or
securities, cash and/or any other property, then in any such case Units of
Series A Preferred Stock shall at the same time be similarly exchanged for or
converted into an amount per Unit (subject to the provision for adjustment
hereinafter set forth) equal to the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is converted or exchanged.  In the event
the Corporation shall at any time after the Rights Declaration Date (i) declare
any dividend on outstanding shares of Common Stock payable in shares of Common
Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the immediately preceding sentence with respect to the
exchange or conversion of Units of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which shall be the number
of shares of Common Stock that are outstanding immediately after such event and
the denominator of

                                       8
<PAGE>
 
which shall be the number of shares of Common Stock that were outstanding
immediately prior to such event.

     Section 8.  Redemption.  The Units of Series A Preferred Stock shall not be
                 ----------
redeemable.

     Section 9.  Ranking.  The Units of Series A Preferred Stock shall rank
                 -------
junior to all other series of the Preferred Stock and to any other class of
preferred stock that hereafter may be issued by the Corporation as to the
payment of dividends and the distribution of assets, unless the terms of any
such series or class shall provide otherwise.

     Section 10.  Amendment.  The Certificate, including, without limitation,
                  ---------
this resolution, shall not hereafter be amended, either directly or indirectly,
or through merger or consolidation with another corporation, in any manner that
would alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority or more of the outstanding Units of Series A Preferred
Stock, voting separately as a class.

     Section 11.  Fractional Shares.  The Series A Preferred Stock may be issued
                  -----------------
in Units or other fractions of a share, which Units or fractions shall entitle
the holder, in proportion to such holder's fractional shares, to exercise voting
rights, receive dividends, participate in distributions and to have the benefit
of all other rights holders of Series A Preferred Stock.

     Section 12.  Certain Definitions.  As used herein with respect to the
                  -------------------
Series A Preferred Stock, the following terms shall have the following meanings:

Disqualified Stock by the Company, Consolidated EBITDA and Consolidated
Indebtedness and Liquidation Preference for such period will be calculated after
giving effect on a pro forma basis to (A) such Indebtedness, Disqualified Stock
or Preferred Stock, as applicable, as if such Indebtedness had been incurred or
such stock had been issued on the first day of such period, (B) the discharge of
any other Indebtedness or Preferred Stock repaid, repurchased, defeased or

<PAGE>

the beginning of such period the Company or any Subsidiary of the Company has
made any sale of assets (including, without limitation, any Asset Sales or
pursuant to any Sale and Leaseback Transaction), Consolidated EBITDA for such
period will be (A) reduced by an amount equal to Consolidated EBITDA (if
positive) directly attributable to the assets which are the subject of such sale
of assets for such period or (B) increased by an amount equal to Consolidated
EBITDA (if negative) directly attributable thereto for such period and (3) if
since the beginning of such period the Company or any Subsidiary of the Company

acquisition of assets, including, without limitation, any acquisition of assets
occurring in connection with a transaction causing a calculation of Consolidated
EBITDA to be made hereunder, which constitutes all or substantially all of an
operating unit of a business, Consolidated EBITDA for such period will be
calculated after giving pro forma effect thereto (including the incurrence of
any Indebtedness (including Acquired Debt)) as if such Investment or acquisition
occurred on the first day of such period. For purposes of this definition,
whenever pro forma effect is to be given to an acquisition of assets, the pro
forma calculations will be determined in good faith by a responsible financial
or accounting Officer of the Company, provided, however, that such Officer shall

additional shares of Exchangeable Preferred Stock shall constitute "payment" of
the related dividend for all purposes of this Certificate of Designation. The
first dividend payment of Exchangeable Preferred Stock shall be payable on June
30, 1997. Dividends payable on the Exchangeable Preferred Stock will be computed
on the basis of a 360-day year consisting of twelve 30- day months and will be
deemed to accrue on a daily basis.

        (b) Dividends on the Exchangeable Preferred Stock shall accrue whether
or not the Company has earnings or profits, whether or not there are funds
legally available for the payment of such dividends and whether or not dividends
are declared. Dividends will accumulate to the extent they are not paid on the
Dividend Payment Date for the period to which they relate. The Company shall
take all actions required or permitted under the Delaware General Corporation
Law (the "DGCL") to permit the payment of dividends on the Exchangeable
Preferred Stock, including, without limitation, through the revaluation of its
assets in accordance with the DGCL, to make or keep funds legally available for
the payment of dividends.

        (c) No dividend whatsoever shall be declared or paid upon, or any sum
set apart for the payment of dividends upon, any outstanding share of the
Exchangeable Preferred Stock with respect to any dividend period unless all
dividends for all preceding dividend periods have been declared and paid, or
declared and a sufficient sum set apart for the payment of such dividend, upon
all outstanding shares of Exchangeable Preferred Stock. Unless full cumulative
dividends on all outstanding shares of Exchangeable Preferred Stock for all past
dividend periods shall have been declared and paid, or declared and a sufficient
sum for the payment thereof set apart, then: (i) no dividend (other than a
dividend payable solely in shares of any Junior Securities) shall be declared or
paid upon, or any sum set apart for the payment of dividends upon, any shares of
Junior Securities; (ii) no other distribution shall be declared or made upon, or
any sum set apart for the payment of any distribution upon, any shares of Junior
Securities, other than a distribution consisting solely of Junior Securities;
(iii) no shares of Junior Securities shall be purchased, redeemed or otherwise
acquired or retired for value (excluding an exchange for shares of other Junior
Securities) by the Company or any of its Subsidiaries; and (iv) no monies shall
be paid into or set apart or made available for a sinking or other like 

                                       12
<PAGE>
 
fund for the purchase, redemption or other acquisition or retirement for value
of any shares of Junior Securities by the Company or any of its Subsidiaries.
Holders of the Exchangeable Preferred Stock will not be entitled to any
dividends, whether payable in cash, property or stock, in excess of the full
cumulative dividends as herein described.

        4.     Liquidation Rights.
               ------------------

        Upon any voluntary or involuntary liquidation, dissolution or winding-up
of the Company or reduction or decrease in its capital stock resulting in a
distribution of assets to the holders of any class or series of the Company's
capital stock, each holder of shares of the Exchangeable Preferred Stock will be
entitled to payment out of the assets of the Company available for distribution
of an amount equal to the Liquidation Preference per share of Exchangeable
Preferred Stock held by such holder, plus accrued and unpaid dividends and
Liquidated Damages, if any, to the date fixed for liquidation, dissolution,
winding-up or reduction or decrease in capital stock, before any distribution is
made on any Junior Securities, including, without limitation, common stock of
the Company. After payment in full of the Liquidation Preference and all accrued
dividends and Liquidated Damages, if any, to which holders of Exchangeable
Preferred Stock are entitled, such holders will not be entitled to any further
participation in any distribution of assets of the Company. If, upon any
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
the amounts payable with respect to the Exchangeable Preferred Stock and all
other Parity Securities are not paid in full, the holders of the Exchangeable
Preferred Stock and the Parity Securities will share equally and ratably in any
distribution of assets of the Company in proportion to the full liquidation
preference and accumulated and unpaid dividends and Liquidated Damages, if any,
to which each is entitled. However, neither the voluntary sale, conveyance,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the property or assets of the
Company nor the consolidation or merger of the Company with or into one or more
Persons will be deemed to be a voluntary or involuntary liquidation, dissolution
or winding-up of the Company or reduction or decrease in capital stock, unless
such sale, conveyance, exchange or transfer shall be in connection with a
liquidation, dissolution or winding-up of the business of the Company or
reduction or decrease in capital stock.

        5.     Redemption by the Company.
               -------------------------

        (a) On March 31, 2009 (the "Mandatory Redemption Date"), the Company
shall be required to redeem (subject to the legal availability of funds
therefor) all outstanding shares of Exchangeable Preferred Stock at a price in
cash equal to the Liquidation Preference thereof, plus accumulated and unpaid
dividends (including an amount in cash equal to a prorated dividend for any
partial dividend period) and Liquidated Damages, if any, to the date of
redemption. The Company shall not be required to make sinking fund payments with
respect to the Exchangeable Preferred Stock. The Company shall take all actions
required or permitted under the DGCL to permit such redemption.

        (b) The Exchangeable Preferred Stock may not be redeemed at the option
of the Company prior to March 31, 2002. The Exchangeable Preferred Stock may be
redeemed, in whole or in part, at the option of the Company on or after March
31, 2002, at the Applicable Redemption Price. Notwithstanding the foregoing
sentence, prior to March 31, 2000, the Company may, on any one or more
occasions, use the net proceeds of one or more underwritten public offerings of
its Common Stock or the sale or sales of its Capital Stock (other than
Disqualified Stock) to a Strategic Investor provided that the proceeds of such
offerings and sales are at least equal to $50 million, to redeem up to 35% of
the shares of Exchangeable Preferred Stock then outstanding (whether initially
issued or issued in lieu of cash dividends) at a redemption price equal to 113
1/2% of the Liquidation Preference per share plus, accumulated and unpaid
dividends and Liquidated Damages, if 

                                       13
<PAGE>
 
any, to the date of redemption; provided that, after any such redemption, at
least 65% of Exchangeable Preferred Stock initially issued remains outstanding.

        (c) In case of redemption of less than all of the shares of Exchangeable
Preferred Stock at the time outstanding, the shares to be redeemed shall be
selected pro rata or by lot as determined by the Company in its sole discretion.

        (d) Notice of any redemption shall be sent by or on behalf of the
Company not less than 30 nor more than 60 days prior to the date specified for
redemption in such notice (including the Mandatory Redemption Date, the
"Redemption Date"), by first class mail, postage prepaid, to all holders of
record of the Exchangeable Preferred Stock at their last addresses as they shall
appear on the books of the Company; provided, however, that no failure to give
such notice or any defect therein or in the mailing thereof shall affect the
validity of the proceedings for the redemption of any shares of Exchangeable
Preferred Stock except as to the holder to whom the Company has failed to give
notice or except as to the holder to whom notice was defective. In addition to
any information required by law or by the applicable rules of any exchange upon
which Exchangeable Preferred Stock may be listed or admitted to trading, such
notice shall state: (i) whether such redemption is being made pursuant to the
optional or the mandatory redemption provisions hereof; (ii) the Redemption
Date; (iii) the Applicable Redemption Price; (iv) the number of shares of
Exchangeable Preferred Stock to be redeemed and, if less than all shares held by
such holder are to be redeemed, the number of such shares to be redeemed; (v)
the place or places where certificates for such shares are to be surrendered for
payment of the Applicable Redemption Price, including any procedures applicable
to redemptions to be accomplished through book-entry transfers; and (vi) that
dividends on the shares to be redeemed will cease to accumulate on the
Redemption Date. Upon the mailing of any such notice of redemption, the Company
shall become obligated to redeem at the time of redemption specified thereon all
shares called for redemption.

        (e) If notice has been mailed in accordance with Section 5(d) above and
provided that on or before the Redemption Date specified in such notice, all
funds necessary for such redemption shall have been set aside by the Company,
separate and apart from its other funds in trust for the pro rata benefit of the
holders of the shares so called for redemption, so as to be, and to continue to
be available therefor, then, from and after the Redemption Date, dividends on
the shares of the Exchangeable Preferred Stock so called for redemption shall
cease to accumulate, and said shares shall no longer be deemed to be outstanding
and shall not have the status of shares of Exchangeable Preferred Stock, and all
rights of the Holders thereof as stockholders of the Company (except the right
to receive from the Company the Applicable Redemption Price) shall cease. Upon
surrender, in accordance with said notice, of the certificates for any shares so
redeemed (properly endorsed or assigned for transfer, if the Company shall so
require and the notice shall so state), such shares shall be redeemed by the
Company at the Applicable Redemption Price. In case fewer than all the shares
represented by any such certificate are redeemed, a new certificate or
certificates shall be issued representing the unredeemed shares without cost to
the holder thereof.

        (f) Any funds deposited with a bank or trust company for the purpose of
redeeming Exchangeable Preferred Stock shall be irrevocable except that:

               (i) the Company shall be entitled to receive from such bank or
        trust company the interest or other earnings, if any, earned on any
        money so deposited in trust, and the holders of any shares redeemed
        shall have no claim to such interest or other earnings; and

               (ii) any balance of monies so deposited by the Company and
        unclaimed by the holders of the Exchangeable Preferred Stock entitled
        thereto at the expiration of two years from the applicable Redemption
        Date shall be repaid, together with any interest or other earnings
        earned thereon, to the 

                                       14
<PAGE>
 
        Company, and after any such repayment, the holders of the shares
        entitled to the funds so repaid to the Company shall look only to the
        Company for payment without interest or other earnings.

        (g) No Exchangeable Preferred Stock may be redeemed except with funds
legally available for the purpose. The Company shall take all actions required
or permitted under the DGCL to permit any such redemption.

        (h) Notwithstanding the foregoing provisions of this Section 5, unless
the full cumulative dividends on all outstanding shares of Exchangeable
Preferred Stock shall have been paid or contemporaneously are declared and paid
for all past dividend periods, none of the shares of Exchangeable Preferred
Stock shall be redeemed unless all outstanding shares of Exchangeable Preferred
Stock are simultaneously redeemed.

        (i) All shares of Exchangeable Preferred Stock redeemed pursuant to this
Section 5 shall be restored to the status of authorized and unissued shares of
preferred stock, without designation as to series and may thereafter be reissued
as shares of any series of preferred stock other than shares of Exchangeable
Preferred Stock.

        6.     Exchange.
               --------

        (a) The Company may, at its option, on any Dividend Payment Date,
exchange, in whole, but not in part, the then outstanding shares of Exchangeable
Preferred Stock for Debentures; provided, that on the date of such exchange (i)
there are no accumulated and unpaid dividends and Liquidated Damages, if any, on
the Exchangeable Preferred Stock (including the dividends payable on such date)
or other contractual impediments to such exchange; (ii) there shall be legally
available funds sufficient therefor; (iii) immediately after giving effect to
such exchange, no Default or Event of Default would exist under the Indenture
and; (iv) the Indenture has been qualified under the Trust Indenture Act, if
such qualification is required at the time of exchange; and (v) the Company
shall have delivered a written opinion of counsel to the Trustee to the effect
that all conditions to be satisfied prior to such exchange have been satisfied.

        (b) The Debentures shall be issuable in principal amounts of $1,000 and
integral multiples thereof to the extent possible, and shall also be issuable in
principal amounts less than $1,000 so that each holder of Exchangeable Preferred
Stock will receive certificates representing the entire amount of Debentures to
which such holder's shares of Exchangeable Preferred Stock entitle such holder;
provided that the Company may pay cash in lieu of issuing any Debentures having
a principal amount less than $1,000. Notice of the intention to exchange shall
be sent by or on behalf of the Company not more than 60 days nor less than 30
days prior to the date fixed for the exchange (the "Exchange Date"), by first
class mail, postage prepaid, to each holder of record of Exchangeable Preferred
Stock at its registered address. In addition to any information required by law
or by the applicable rules of any exchange upon which the Exchangeable Preferred
Stock may be listed or admitted to trading, such notice shall state: (i) the
Exchange Date; (ii) the place or places where certificates for such shares are
to be surrendered for exchange, including any procedures applicable to exchanges
to be accomplished through book-entry transfers; and (iii) that dividends on the
shares of Exchangeable Preferred Stock to be exchanged will cease to accumulate
on the Exchange Date.

        (c) A holder delivering Exchangeable Preferred Stock for exchange shall
not be required to pay any taxes or duties in respect of the issue or delivery
of Debentures on exchange but shall be required to pay any tax or duty that may
be payable in respect of any transfer involved in the issue or delivery of the
Debentures in a name other than that of the holder of the Exchangeable Preferred
Stock. Certificates representing Debentures shall not be issued or delivered
unless all taxes and duties, if any, payable by the holder have been paid.

                                       15
<PAGE>
 
        (d) If notice of any exchange has been properly given, and if on or
before the Exchange Date the Debentures have been duly executed and
authenticated and an amount in cash or additional shares of Exchangeable
Preferred Stock (as applicable) equal to all accumulated and unpaid dividends
and Liquidated Damages, if any, thereon to the Exchange Date has been deposited
with the Transfer Agent, then on and after the close of business on the Exchange
Date, the shares of Exchangeable Preferred Stock to be exchanged shall no longer
be deemed to be outstanding and may thereafter be issued in the same manner as
the other authorized but unissued preferred stock, but not as Exchangeable
Preferred Stock, and all rights of the holders thereof as stockholders of the
Company shall cease, except the right of the holders to receive upon surrender
of their certificates the Debentures and all accrued interest, if any, thereon
to the Exchange Date.

        (e) As a condition to the exercise of the exchange rights described in
this Section 6, the Company shall deliver an opinion to the Trustee as to the
due authorization, execution, delivery and enforceability of both the Debentures
and the Indenture and as to the compliance by the Company with the provisions
hereof.

        7.     Voting Rights.
               -------------

        (a) The holders of record of shares of the Exchangeable Preferred Stock
shall have no voting rights, except as required by law and as hereinafter
provided in this Section 7.

        (b)    Upon:

               (i) the accumulation of accumulated and unpaid dividends on the
        outstanding Exchangeable Preferred Stock in an amount equal to six (6)
        quarterly dividends (whether or not consecutive);

               (ii) the failure of the Company to satisfy any mandatory
        redemption or repurchase obligation (including, without limitation,
        pursuant to any required Change of Control Offer) with respect to the
        Exchangeable Preferred Stock;

               (iii) the failure of the Company to make a Change of Control
        Offer on the terms and in accordance with the provisions described below
        in Section 8 hereof;

               (iv) the failure of the Company to comply with any of the other
        covenants or agreements set forth in this Certificate of Designation and
        the continuance of such failure for 60 consecutive days or more after
        notice; or

               (v) default under any mortgage, indenture or instrument under
        which there may be issued or by which there may be secured or evidenced
        any Indebtedness for money borrowed by the Company or any of its
        Subsidiaries (or the payment of which is guaranteed by the Company or
        any of its Subsidiaries) whether such Indebtedness or Guarantee now
        exists, or is created after the Closing Date, which default (1) is
        caused by a failure to pay principal of or premium, if any, or interest
        on such Indebtedness prior to the expiration of the grace period
        provided in such Indebtedness on the date of such default (a "Payment
        Default") or (2) results in the acceleration of such Indebtedness prior
        to its express maturity and, in each case, the principal amount of any
        such Indebtedness, together with the 

                                       16
<PAGE>
 
        principal amount of any other such Indebtedness under which there has
        been a Payment Default or the maturity of which has been so accelerated,
        aggregates $5.0 million or more (each of the events described in clauses
        (i), (ii), (iii), (iv) and (v) being referred to herein as a "Voting
        Rights Triggering Event");

then the holders of a majority of the outstanding shares of Exchangeable
Preferred Stock, voting as a separate single class, shall be entitled to elect
such number of members to the Board of Directors of the Company constituting at
least 20% of the then existing Board of Directors before such election (rounded
to the nearest whole number), provided, however, that such number shall be no
less than one nor greater than two, and the number of members of the Company's
Board of Directors shall be immediately and automatically increased by one or
two, as the case may be. The voting rights provided for in this Section 7 shall
be the exclusive remedy for the holders of the Exchangeable Preferred Stock for
any violation by the Company of its obligations under this Certificate of
Designation that constitutes an Event of Default.

        (c) Whenever such voting right shall have vested, such right may be
exercised initially either at a special meeting of the holders of Exchangeable
Preferred Stock, called as hereinafter provided, or at any annual meeting of
stockholders held for the purpose of electing directors, and thereafter at such
annual meetings or by the written consent of the holders of Exchangeable
Preferred Stock. Such right of the holders of Exchangeable Preferred Stock to
elect directors may be exercised until (i) all dividends in arrears shall have
been paid in full and (ii) all other Voting Rights Triggering Events have been
cured or waived, at which time the term of such directors previously elected
shall thereupon terminate, and such directors shall be deemed to have resigned.

        (d) At any time when such voting right shall have vested in the holders
of Exchangeable Preferred Stock and if such right shall not already have been
initially exercised, a proper officer of the Company shall, upon the written
request of holders of record of 10% or more of the Exchangeable Preferred Stock
then outstanding, addressed to the Secretary of the Company, call a special
meeting of holders of Exchangeable Preferred Stock. Such meeting shall be held
at the earliest practicable date upon the notice required for annual meetings of
stockholders at the place for holding annual meetings of stockholders of the
Company or, if none, at a place designated by the Secretary of the Company. If
such meeting shall not be called by the proper officers of the Company within 30
days after the personal service of such written request upon the Secretary of
the Company, or within 30 days after mailing the same within the United States,
by registered mail, addressed to the Secretary of the Company at its principal
office (such mailing to be evidenced by the registry receipt issued by the
postal authorities), then the holders of record of 10% of the shares of
Exchangeable Preferred Stock then outstanding may designate in writing a holder
of Exchangeable Preferred Stock to call such meeting at the expense of the
Company, and such meeting may be called by such person so designated upon the
notice required for annual meetings of stockholders and shall be held at the
place for holding annual meetings of the Company or, if none, at a place
designated by such holder. Any holder of Exchangeable Preferred Stock that would
be entitled to vote at such meeting shall have access to the stock books of the
Company for the purpose of causing a meeting of stockholders to be called
pursuant to the provisions of this Section 7. Notwithstanding the provisions of
this paragraph, however, no such special meeting shall be called if any such
request is received less than 90 days before the date fixed for the next ensuing
annual or special meeting of stockholders.

        (e) If any director so elected by the holders of Exchangeable Preferred
Stock shall cease to serve as a director before his term shall expire, the
holders of Exchangeable Preferred Stock then outstanding may, at a special
meeting of the holders called as provided above, elect a successor to hold
office for the unexpired term of the director whose place shall be vacant.

                                       17
<PAGE>
 
        (f) The Company shall not, without the affirmative vote or consent of
the holders of at least a majority of the shares of Exchangeable Preferred Stock
then outstanding (with shares held by the Company or any of its Affiliates not
being considered to be outstanding for this purpose) voting or consenting as the
case may be, as one class:

               (i) authorize, create (by way of reclassification or otherwise)
        or issue any Senior Securities or any obligation or security convertible
        into or evidencing the right to purchase, shares of any class or series
        of Senior Securities, except, the Company may issue Senior Securities
        pursuant to Section 9(b) hereof;

               (ii) authorize, create (by way of reclassification or otherwise)
        or issue any Parity Securities or any obligation or security convertible
        or exchangeable into or evidencing a right to purchase, shares of any
        class or series of Parity Securities, except, the Company may issue: (i)
        shares of the Series B Preferred Stock as provided herein, (ii) shares
        of Exchangeable Preferred Stock to pay dividends thereon in accordance
        with the terms of this Certificate of Designation, and (iii) Parity
        Securities pursuant to Section 9(b) hereof;

               (iii) amend or otherwise alter this Certificate of Designation
        (including the provisions of Section 8 hereof) in any manner that
        adversely affects the specified rights, preferences, privileges or
        voting rights of holders of Exchangeable Preferred Stock (a change in
        the initial Liquidation Preference per share of the Series B Preferred
        Stock not being deemed to be adverse, provided that the aggregate
        Liquidation Preference of the Series B Preferred Stock is equal to the
        aggregate Liquidation Preference of the Series A Preferred Stock
        exchanged for the Series B Preferred Stock);

               (iv) authorize the issuance of any additional shares of
        Exchangeable Preferred Stock (except for increases resulting from a
        change in the Liquidation Preference of the Series B Preferred Stock or
        resulting from a 10 for 1 stock split of the Series B Preferred Stock,
        provided that, in each case, the aggregate Liquidation Preference of the
        Series B Preferred Stock is equal to the aggregate Liquidation
        Preference of the Series A Preferred Stock exchanged for the Series B
        Preferred Stock); or

               (v) waive any existing Voting Rights Triggering Event or
        compliance with any provision of this Certificate of Designation;

provided, however, that (a) the Company may not amend the Change of Control
provisions of this Certificate of Designation (including the related
definitions) without the approval of the holders of at least 662/3% of the then
outstanding shares of Exchangeable Preferred Stock, voting or consenting, as the
case may be, as one class and (b) without the consent of the holders of the
Exchangeable Preferred Stock, the Company will have the ability to issue
additional shares of Exchangeable Preferred Stock to pay dividends.

        (g) Without the consent of each holder affected, an amendment or waiver
of the Company's Certificate of Incorporation or of this Certificate of
Designation may not (with respect to any shares of Exchangeable Preferred Stock
held by a non-consenting holder):

               (i) alter the voting rights with respect to the Exchangeable
        Preferred Stock or reduce the number of shares of Exchangeable Preferred
        Stock whose holders must consent to an amendment, supplement or waiver;

                                       18
<PAGE>
 
               (ii) reduce the Liquidation Preference of or change the Mandatory
        Redemption Date of any share of Exchangeable Preferred Stock or alter
        the provisions with respect to the redemption of the Exchangeable
        Preferred Stock (except as provided with respect to Section 8 hereof and
        except that the Company may reduce the Liquidation Preference on the
        Series B Preferred Stock prior to its issuance or effect a 10 for 1
        stock split with respect to the Series B Preferred Stock, provided that,
        in each case, the aggregate Liquidation Preference of the Series B
        Preferred Stock is equal to the aggregate Liquidation Preference of the
        Series A Preferred Stock exchanged for the Series B Preferred Stock);

               (iii) reduce the rate of or change the time for payment of
        dividends on any share of Exchangeable Preferred Stock;

               (iv) waive the consequences of any failure to pay dividends on
        the Exchangeable Preferred Stock;

               (v) make any share of Exchangeable Preferred Stock payable in any
        form other than that stated in this Certificate of Designation;

               (vi) make any change in the provisions of this Certificate of
        Designation relating to waivers of the rights of holders of Exchangeable
        Preferred Stock to receive the Liquidation Preference and dividends on
        the Exchangeable Preferred Stock;

               (vi) waive a redemption payment with respect to any share of
        Exchangeable Preferred Stock (except as provided with respect to Section
        8 hereof); or

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

        (h) The Company in its sole discretion may without the vote or consent
of any holders of the Exchangeable Preferred Stock amend or supplement this
Certificate of Designation:

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

               (ii) to provide for uncertificated Exchangeable Preferred Stock
        in addition to or in place of certificated Exchangeable Preferred Stock;
        or

               (iii) to make any change that would provide any additional rights
        or benefits to the holders of the Exchangeable Preferred Stock or that
        does not adversely affect the legal rights under this Certificate of
        Designation of any such holder.

Except as set forth above, (a) the creation, authorization or issuance of any
shares of Junior Securities, Parity Securities or Senior Securities or (b) the
increase or decrease in the amount of authorized capital stock of any class,
including any preferred stock, shall not require the consent of the holders of
the Exchangeable Preferred Stock and shall not be deemed to affect adversely the
rights, preferences, privileges, special rights or voting rights of holders of
shares of Exchangeable Preferred Stock.

        8.     Change of Control.
               -----------------

        (a) Upon the occurrence of a Change of Control, the Company shall make
an offer (the "Change of Control Offer") to each holder of shares of
Exchangeable Preferred Stock to repurchase all or any part (but 

                                       19
<PAGE>
 
not, in the case of any holder requiring the Company to purchase less than all

fractional shares) of such holder's Exchangeable Preferred Stock at an offer

accumulated and unpaid dividends and Liquidated Damages, if any, thereon to the
date of purchase (the "Change of Control Payment").

        (b) The Change of Control Offer shall include all instructions and
materials necessary to enable holders to tender their shares of Exchangeable
Preferred Stock.

        (c) The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the

Control.

mail a notice to each holder stating:

               (i) that the Change of Control Offer is being made pursuant to
        this Section 8 and that all shares of Exchangeable Preferred Stock
        tendered will be accepted for payment;

               (ii) the purchase price and the purchase date, which shall be no
        earlier than 30 days nor later than 60 days from the date such notice is
        mailed (the "Change of Control Payment Date");

               (iii) that any share of Exchangeable Preferred Stock not tendered
        will continue to accumulate dividends;

               (iv) that, unless the Company fails to pay the Change of Control
        Payment, all shares of Exchangeable Preferred Stock accepted for payment
        pursuant to the Change of Control Offer shall cease to accumulate
        dividends after the Change of Control Payment Date;

               (v) that holders electing to have any shares of Exchangeable
        Preferred Stock purchased pursuant to a Change of Control Offer will be
        required to surrender the shares of Exchangeable Preferred Stock, with
        the form entitled "Option of Holder to Elect Purchase" which shall be
        included with the Notice of Change of Control completed, to the Paying
        Agent at the address specified in the notice prior to the close of
        business on the third Business Day preceding the Change of Control
        Payment Date;

               (vi) that holders will be entitled to withdraw their election if
        the Paying Agent receives, not later than the close of business on the
        second Business Day preceding the Change of Control Payment Date, a
        telegram, telex, facsimile transmission or letter setting forth the name
        of the holder, the number of shares of Exchangeable Preferred Stock
        delivered for purchase, and a statement that such holder is withdrawing
        his election to have such shares purchased; and

               (vii) the circumstances and relevant facts regarding such Change
        of Control (including, but not limited to, information with respect to
        pro forma historical financial information after giving effect to such
        Change of Control and information regarding the Person or Persons
        acquiring control).

        (e) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) accept for payment all shares of Exchangeable Preferred Stock
or portions thereof properly tendered pursuant to the Change of Control Offer,

                                       20

Payment in respect of all shares of Exchangeable Preferred Stock or portions
thereof so tendered and (iii) deliver or cause to be delivered to the Transfer
Agent the shares of Exchangeable Preferred Stock so accepted together with an
Officers' Certificate stating the aggregate Liquidation Preference of the shares
of Exchangeable Preferred Stock or portions thereof being purchased by the
Company. The Paying Agent shall promptly mail to each holder of Exchangeable
Preferred Stock so tendered the Change of Control Payment for such Exchangeable
Preferred Stock, and the Transfer Agent shall promptly authenticate and mail (or
cause to be transferred by book entry) to each holder a new certificate
representing the shares of Exchangeable Preferred Stock equal in Liquidation
Preference amount to any unpurchased portion of the shares of Exchangeable
Preferred Stock surrendered, if any. The Company shall publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

        (f) If, at the time of a Change of Control, the Company is prohibited by
the terms of any Indebtedness from purchasing shares of Exchangeable Preferred
Stock that may be tendered by holders pursuant to a Change of Control Offer,
prior to complying with the provisions of this Section 8, but in any event
within 90 days following a Change of Control, the Company shall either (i) repay
in full all outstanding Indebtedness or (ii) obtain the requisite consents, if
any, under all agreements governing outstanding Indebtedness to permit the
repurchase of Exchangeable Preferred Stock required by this covenant. The
Company must first comply with the covenant described in the preceding sentence
before it will be required to repurchase shares of Exchangeable Preferred Stock
in the event of a Change of Control; provided, that if the Company fails to
comply with the covenant described in the preceding sentence, the sole remedy to
holders of Exchangeable Preferred Stock will be the voting rights arising from a
Voting Rights Triggering Event. Moreover, the Company will not repurchase or
redeem any Exchangeable Preferred Stock pursuant to this Change of Control
provision prior to the Company's repurchase of the Existing Senior Notes
pursuant to the Change of Control covenants in the Existing Senior Notes
Indentures.

        (g) The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set
forth in this Section 8 applicable to a Change of Control Offer made by the
Company and purchases all shares of Exchangeable Preferred Stock validly
tendered and not withdrawn under such Change of Control Offer.

        9.     Certain Covenants

        (a)    Restricted Payments.

               The Company and its Subsidiaries shall not, directly or
indirectly:

        not Disqualified Stock or (B) to the Company or any Subsidiary;

               (ii) purchase, redeem, defease, retire or otherwise acquire for

        actions set forth in clauses (i) through (iii) above being collectively
        referred to as "Restricted Payments"), unless, at the time of such
        Restricted Payment:

                      (A) no Default or Event of Default has occurred and is
               continuing or would occur as a consequence thereof;

                      (B) after giving effect to such Restricted Payment on a
               pro forma basis as if such Restricted Payment had been made at
               the beginning of the applicable four-quarter period, the Company
               could incur at least $1.00 of additional Indebtedness pursuant to
               the Consolidated Cash Flow Leverage Ratio test described under
               Section 9(b) hereof; and

                      (C) such Restricted Payment, together with the aggregate
               of all other Restricted Payments made by the Company and its
               Subsidiaries after the Issue Date including any Restricted
               Payments made pursuant to clauses (i), (iii) and (iv) of the next
               paragraph), is less than the sum of

                             (w) 50% of the Consolidated Net Income of the
                      Company for the period (taken as one accounting period)
                      from the beginning of the first fiscal quarter commencing
                      after the Issue Date to the end of the Company's most
                      recently ended fiscal quarter for which internal financial
                      statements are available at the time of such Restricted
                      Payment (or, if such Consolidated Net Income for such
                      period is a deficit, less 100% of such deficit), plus

                             (x) 100% of the aggregate net cash proceeds
                      received by the Company from the issue or sale of Equity
                      Interests of the Company or of debt securities or
                      Disqualified Stock of the Company that have been converted
                      into such Equity Interests (other than Equity Interests
                      (or convertible debt securities) sold to a Subsidiary of
                      the Company and other than Disqualified Stock or debt
                      securities that have been converted into Disqualified
                      Stock) after the Issue Date (other than any such Equity
                      Interests, the proceeds of which were used as set forth in
                      clause (ii) below), plus

                             (y) 100% of the sum of, without duplication, (1)
                      aggregate dividends or distributions received by the
                      Company or any Subsidiary from any Joint Venture (other
                      than dividends or distributions to pay any obligations of
                      such Joint Venture to Persons other than the Company or
                      any Subsidiary, such as income taxes), with non-cash
                      distributions to be valued at the lower of book value or
                      Fair Market Value as determined by the Board of Directors,
                      (2) the amount of the principal and interest payments
                      received since the Issue Date by the Company or any
                      Subsidiary from any Joint Venture and (3) the net proceeds
                      from the sale of an Investment in a Joint Venture received
                      by the Company or any Subsidiary; provided that there is
                      no obligation to return any such amounts to the Joint
                      Venture, and excluding any such dividend, distribution,
                      interest payment or net proceeds that constitutes a return
                      of capital invested pursuant to clause (vi) of the next
                      succeeding paragraph, plus

                             (z) $10.0 million.

               The foregoing provisions will not prohibit:

                                       22
<PAGE>
 
                      (i) the payment of any dividend within 60 days after the
               date of declaration thereof, if at such date of declaration such
               payment would have complied with the provisions hereof;

                      (ii) the Retirement of any Junior Securities of the
               Company or Equity Interests of any Subsidiary of the Company, in
               exchange for, or out of the proceeds of the substantially
               concurrent sale (other than to a Subsidiary of the Company) of,
               Junior Securities of the Company (other than Disqualified Stock)
               or other Equity Interests of such Subsidiary that is not
               Disqualified Stock;

                      (iii) the Retirement of any Junior Securities of the
               Company or any Subsidiary of the Company held by any member of
               the Company's (or any of its Subsidiaries') management pursuant
               to any management equity subscription agreement or stock option
               agreement; provided that the aggregate price paid for all such
               repurchased, redeemed, acquired or retired Equity Interests shall
               not exceed $1.0 million in any twelve-month period plus the
               aggregate cash proceeds received by the Company during such
               twelve-month period from any reissuance of Equity Interests by
               the Company to members of management of the Company and its
               Subsidiaries; and

                      (iv) Investments in any Joint Venture; provided that at
               the time any such Investment is made, such Investment will not
               cause the aggregate amount of Investments at any one time
               outstanding under this clause (vi) to exceed 5% of the Total
               Common Equity of the Company;

provided, however, that at the time of, and after giving effect to, any
Restricted Payment permitted under clauses (i), (ii), (iii), and (iv), no
Default or Event of Default shall have occurred and be continuing.

        A Permitted Investment that ceases to be a Permitted Investment pursuant
to the definition thereof, shall become a Restricted Investment, deemed to have
been made on the date that it ceases to be a Permitted Investment.

        The Board of Directors may designate any Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default or an
Event of Default. For purposes of making such determination, all outstanding
Investments by the Company and its Subsidiaries (except to the extent repaid in
cash) in such Subsidiary so designated will be deemed to be Restricted Payments
at the time of such designation and will reduce the amount available for
Restricted Payments under the first paragraph of this covenant. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the greatest of (x) the net book value of such Investments at the time
of such designation, (y) the Fair Market Value of such Investments at the time
of such designation and (z) the original Fair Market Value of such Investments
at the time they were made. Such designation will only be permitted if such
Restricted Payment would be permitted at such time.

        The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Subsidiary of the Company of
any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (i) such Indebtedness is permitted under
Section 9(b) hereof and (ii) no Default or Event of Default would be in
existence following such designation.

        (b) Incurrence of Indebtedness and Issuance of Disqualified Stock or
Preferred Stock.

                                       23
<PAGE>
 
               (i) The Company and its Subsidiaries shall not, directly or
        indirectly, create, incur, issue, assume, guarantee or otherwise become
        directly or indirectly liable for the payment of (collectively, "incur"
        and, correlatively, "incurred" and "incurrence") any Indebtedness
        (including, without limitation, Acquired Debt) and

               (ii) The Company and its Subsidiaries shall not issue any
        Disqualified Stock or any Preferred Stock,

provided, however, that the Company and/or any of its Subsidiaries may incur
Indebtedness (including, without limitation, Acquired Debt) or issue shares of
Disqualified Stock or any Preferred Stock if, after giving effect to the
incurrence of such Indebtedness or the issuance of such Disqualified Stock or
Preferred Stock, the Consolidated Cash Flow Leverage Ratio for the Company's
most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date of such incurrence or
issuance (A) does not exceed 6.5 to 1 if such incurrence or issuance occurs on
or prior to June 1, 1999 and (B) does not exceed 6.0 to 1 if such occurrence or
issuance occurs after June 1, 1999, in each case, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred, or the Disqualified Stock or
Preferred Stock had been issued, as the case may be, at the beginning of such
four-quarter period. If the Company incurs any Indebtedness or issues or redeems
any Preferred Stock or Disqualified Stock subsequent to the commencement of the
period for which such ratio is being calculated but prior to the event for which
the calculation of the ratio is made, then the ratio will be calculated giving
pro forma effect to any such incurrence of Indebtedness, or such issuance or
redemption of Preferred Stock or Disqualified Stock as if the same had occurred
at the beginning of the applicable period. In making such calculation on a pro
forma basis, interest attributable to Indebtedness bearing a floating interest
rate shall be computed as if the rate in effect on the date of computation had
been the applicable rate for the entire period.

        The foregoing limitation will not apply to (with each exception to be
given independent effect):

        (a) the incurrence by the Company and/or any of its Subsidiaries of
Indebtedness under the Credit Facility in an aggregate principal amount at any
one time outstanding (with letters of credit being deemed to have a principal
amount equal to the maximum potential liability of the Company and/or any of its
Subsidiaries thereunder) not to exceed $75.0 million in the aggregate at any one
time outstanding;

        (b) the incurrence by the Company and/or any of its Subsidiaries of
Vendor Indebtedness, provided that the aggregate amount of such Vendor
Indebtedness incurred does not exceed 80% of the total cost of the
Telecommunications Related Assets financed therewith (or 100% of the total cost
of the Telecommunications Related Assets financed therewith if such Vendor
Indebtedness was extended for the purchase of tangible physical assets and was
so financed by the vendor thereof or an affiliate of such vendor);

        (c) the incurrence by the Company and/or any of its Subsidiaries of the
Existing Indebtedness, including the Existing Senior Notes; and the Series B
Preferred Stock issued in exchange for the Series A Preferred Stock pursuant to
the Registration Rights Agreement (and any shares of Exchangeable Preferred
Stock issued as dividends thereon):

        (d) the incurrence by the Company and/or any of its Subsidiaries of
Indebtedness in an aggregate amount not to exceed $25.0 million at any one time
outstanding;

        (e) the incurrence by the Company of Indebtedness or Preferred Stock in
an aggregate principal amount and liquidation preference not to exceed 2.0 times
the net cash proceeds received by the Company after 

                                       24
<PAGE>
 
the Issue Date from the issuance and sale of Equity Interests of the Company
plus the fair market value of Equity Interests (other than Disqualified Stock)
issued in connection with any acquisition of any Telecommunications Business;

        (f) the incurrence by the Company and/or any of its Subsidiaries of
Acquired Debt in connection with any acquisition of any Telecommunications
Business in an amount not to exceed $50.0 million;

        (g) the incurrence (a "Permitted Refinancing") by the Company and/or any
of its Subsidiaries of Indebtedness issued in exchange for, or the proceeds of
which are used to refinance, replace, refund or defease ("Refinance" and
correlatively, "Refinanced" and "Refinancing") Indebtedness (or the incurrence
of Preferred Stock or Disqualified Stock to Refinance Preferred Stock or
Disqualified Stock, as the case may be), other than Indebtedness incurred
pursuant to clause (a) above, but only to the extent that:

               (1) the net proceeds of such Refinancing Indebtedness or
        Refinancing Capital Stock, as the case may be, does not exceed the
        principal amount of and premium, if any, and accrued interest on the
        Indebtedness so Refinanced (or if such Indebtedness was issued at an
        original issue discount, the original issue price plus amortization of
        the original issue discount at the time of the repayment of such
        Indebtedness) or the liquidation preference of the Capital Stock so
        Refinanced plus the fees, expenses and costs of such Refinancing and
        reasonable prepayment premiums, if any, in connection therewith;

               (2) the Refinancing Indebtedness or the Refinancing Capital
        Stock, as the case may be, shall have a final maturity no earlier than,
        and a Weighted Average Life to Maturity equal to or greater than, the
        final maturity and Weighted Average Life to Maturity of the Indebtedness
        or Capital Stock being Refinanced; and

               (3) if the Capital Stock being Refinanced is subordinated in
        right of payment to the Exchangeable Preferred Stock, the Refinancing
        Capital Stock shall be subordinated in right of payment to the
        Exchangeable Preferred Stock on terms at least as favorable to the
        holders of Exchangeable Preferred Stock as those contained in the
        documentation governing the Capital Stock being so Refinanced;

        (h) the incurrence by the Company or any of its Subsidiaries of
intercompany Indebtedness between or among the Company and any of its
Subsidiaries;

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

        (j) the incurrence by the Company of Junior Securities that are not
Disqualified Stock; and

        (k) the incurrence by the Company of the Debentures in accordance with
the terms of this Certificate of Designation.

        For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness, Disqualified Stock or Preferred Stock meets the
criteria of more than one of the categories described in clauses (a) through (k)
above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Company shall, in its sole discretion, classify such item in any
manner that complies with this covenant and such item will be treated as having
been incurred pursuant to only one of such clauses or pursuant to the first
paragraph herein. Accrual of interest or dividends, the accretion of accreted
value or liquidation preference and the

                                       25
<PAGE>
 
payment of interest or dividends in the form or additional Indebtedness or
Preferred Stock will not be deemed to be an incurrence of Indebtedness for
purposes of this covenant.

        (c)    Dividend and Other Payment Restrictions Affecting Subsidiaries.

        The Company and its Subsidiaries shall not, directly or indirectly,
create or otherwise cause to become effective any consensual encumbrance or
restriction on the ability of any Subsidiary to:

               (i) pay dividends or make any other distributions to the Company
        or any of its Subsidiaries on its Capital Stock or with respect to any
        other interest or participation in, or measured by, its profits, or pay
        any Indebtedness owed to the Company or any of its Subsidiaries;

               (ii) make loans or advances to the Company or any of its
        Subsidiaries; or

               (iii) transfer any of its properties or assets to the Company or
        any of its Subsidiaries; except for such encumbrances or restrictions
        existing as of the Issue Date or under or by reason of:

        (a) Existing Indebtedness;

        (b) applicable law;

        (c) any instrument governing Acquired Debt as in effect at the time of
acquisition (except to the extent such Indebtedness was incurred in connection
with, or in contemplation of, such acquisition), which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the Person, so
acquired;

        (d) by reason of customary non-assignment provisions in leases entered
into in the ordinary course of business and consistent with past practices;

        (e) Indebtedness or Preferred Stock in respect of a Permitted
Refinancing, provided that the restrictions contained in the agreements
governing such Refinancing Indebtedness or Refinancing Capital Stock are not
materially more restrictive than those contained in the agreements governing the
Indebtedness or Capital Stock being refinanced;

        (f) with respect to clause (iii) above, purchase money obligations for
property acquired in the ordinary course of business, Vendor Indebtedness
incurred in connection with the purchase or lease of Telecommunications Related
Assets or performance bonds or similar security for performance which liens
securing such obligations do not cover any asset other than the asset acquired
or, in the case of performance bonds or similar security for performance, the
assets associated with the Company's performance;

        (g) Indebtedness incurred under clause (a) of the Section 9(b) hereof;

the Company is the surviving entity), or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets in
one or more related transactions to, another corporation, Person or entity
unless:

               (i) the Company is the surviving entity or the entity or Person

               (iii) immediately after such transaction no Default or Event of
        Default exists;

               (iv) if the holders of at least 85% of the common stock of the
        Surviving Person immediately after such transaction are not, directly or
        indirectly, the same as the holders of the common stock of the Company
        immediately prior to such transaction, the Surviving Person, at the time

otherwise dispose of any of their respective properties or assets to, or
purchase any property or assets from, or enter into any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless:

               (i) such Affiliate Transaction is on terms that are no less
        favorable to the Company or the relevant Subsidiary than those that
        would have been obtained in a comparable transaction by the Company or

<PAGE>
 
               (ii) such Affiliate Transaction is approved by a majority of the
        disinterested directors on the Board of Directors of the Company;

provided that

        (a) transactions pursuant to any employment, stock option or stock
purchase agreement entered into by the Company or any of its Subsidiaries, or

Board of Directors of the Company,

        The Company shall file within 15 days after it files them with the
Commission copies of the annual and quarterly reports and the information,
documents, and other reports that the Company is required to file with the
Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC
Reports"). In the event the Company is not required or shall cease to be
required to file SEC Reports, pursuant to the Exchange Act, the Company will
nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing). Whether or not required by the
Exchange Act to file SEC Reports with the Commission, so long as any
Exchangeable Preferred Stock are outstanding, the Company will furnish copies of
the SEC Reports to the holders of Exchangeable Preferred Stock at the time the
Company is required to make such information available to investors who request
it in writing. In addition, the Company has agreed that, for so long as any
Exchangeable Preferred Stock remain outstanding, it will furnish to the holders
and to securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.

        10.    Exchange of Exchangeable Preferred Stock for Debentures.
               -------------------------------------------------------

        (a) The Company may at its option exchange all, but not less than all,
of the then outstanding shares of Exchangeable Preferred Stock into the
Debentures to be issued under an indenture (the "Indenture") in the form
attached hereto as Annex A to be entered into between the Company and a trustee
to be selected by the Company (the "Trustee") on any Dividend Payment Date,
provided that on the date of such exchange: (A) there are no accumulated and
unpaid dividends or Liquidated Damages, if any, on the Exchangeable Preferred
Stock (including the dividends payable and Liquidated Damages on such date) or
other contractual impediments to such exchange; (B) there shall be legally
available funds sufficient therefor; (C) either (i) a registration statement
relating to the Debentures shall have been declared effective under the
Securities Act of 1933, as amended (the "Securities Act"), prior to such
exchange, and shall continue to be in effect on the date of such exchange; or
(ii) (A) the Company shall have obtained a written opinion of counsel that an
exemption from the registration requirements of the Securities Act is available
for such exchange, and that upon receipt of such Debentures pursuant to such
exchange made in accordance with such exemption, the

                                       28
<PAGE>
 
holders (assuming such holder is not an Affiliate of the Company) thereof shall
not be subject to any restrictions imposed by the Securities Act upon the resale
thereof other than any such restrictions to which the holder thereof already is
subject on the Exchange Date, and (B) such exemption is relied upon by the
Company for such exchange; (D) if required by applicable law, the Indenture and
the Trustee thereunder shall have been qualified under the Trust Indenture Act
of 1939, as amended; (E) immediately after giving effect to such exchange, no
Default or Event of Default (each as defined in the Indenture) would exist under
the Indenture; and (F) the Company shall have delivered to the Trustee a written
opinion of counsel, dated the date of exchange, to the effect that all
conditions to be satisfied prior to such exchange have been satisfied. In the
event that the issuance of the Debentures is not permitted on the date of
exchange or any of the conditions set forth in clauses (A) through (F) of the
preceding sentence are not satisfied on the date of exchange, the Company shall
use its best efforts to satisfy such conditions and effect such exchange as soon
as practicable.

        The Company shall send a written notice (the "Exchange Notice") of
exchange by mail to each holder of record of Exchangeable Preferred Stock, which
notice shall state: (v) that the Company is exercising its option to exchange
the Exchangeable Preferred Stock for Debentures pursuant to this Certificate of
Designation; (w) the date fixed for exchange (the "Exchange Date"), which date
shall not be less than 30 days nor more than 60 days following the date on which
the Exchange Notice is mailed (except as provided in the last sentence of this
paragraph); (x) that the holder is to surrender to the Company, at the place or
places where certificates for shares of Exchangeable Preferred Stock are to be
surrendered for exchange, including any procedures applicable to exchanges to be
accomplished through book-entry transfers, in the manner designated in the
Exchange Notice, the certificate or certificates representing the shares of
Exchangeable Preferred Stock to be exchanged; (y) that dividends on the shares
of Exchangeable Preferred Stock to be exchanged shall cease to accrue on the
Exchange Date whether or not certificates for shares of Exchangeable Preferred
Stock are surrendered for exchange on the Exchange Date unless the Company shall
default in the delivery of Debentures; and (z) that interest on the Debentures
shall accrue from the Exchange Date whether or not certificates for shares of
Exchangeable Preferred Stock are surrendered for exchange on the Exchange Date.
On the Exchange Date, if the conditions set forth in clauses (A) through (F)
above are satisfied, the Company shall issue Debentures in exchange for the
Exchangeable Preferred Stock as provided in the next paragraph.

        (b) Upon any exchange pursuant to this paragraph 10, Debentures shall be
issued in exchange for Exchangeable Preferred Stock, in registered form without
coupons, in an amount equal the Liquidation Preference thereof, plus an amount
in cash equal to all accumulated and unpaid dividends (including a prorated
dividend for the period from the immediately preceding Dividend Payment Date to
the Exchange Date). Debentures will be issued in principal amounts of $1,000 and
integral multiples thereof to the extent possible, and will also be issued in
principal amounts less than $1,000 so that each holder of Exchangeable Preferred
Stock will receive certificates representing the entire amount of Debentures to
which its shares of Exchangeable Preferred Stock entitles it, provided that the
Company may, at its option, pay cash in lieu of issuing a Debenture in a
principal amount of less than $1,000.

        (c) Procedure for Exchange. (A) On or before the date fixed for
exchange, each holder of Exchangeable Preferred Stock shall surrender the
certificate or certificates representing such shares of Exchangeable Preferred
Stock, in the manner and at the place designated in the Exchange Notice. The
Company shall cause the Debentures to be executed on the Exchange Date and, upon
surrender in accordance with Exchange Notice of the certificates for any shares
of Exchangeable Preferred Stock so exchanged (properly endorsed or assigned for
transfer, if the notice shall so state), such shares shall be exchanged by the
Company for Debentures. The Company shall pay interest and Liquidated Damages,
if any, on the Debentures at the rate and on the dates specified therein from
the Exchange Date.

                                       29
<PAGE>
 
        (d) If notice has been mailed as aforesaid, and if before the Exchange
Date (1) the Indenture shall have been duly executed and delivered by the
Company and the Trustee and (2) all Debentures necessary for such exchange shall
have been duly executed by the Company and delivered to the Trustee with
irrevocable instructions to authenticate the Debentures necessary for such
exchange, then on and after the close of business on the Exchange Date,
dividends shall cease to accrue on the outstanding shares of Exchangeable
Preferred Stock and all of the rights of the holders of shares of the
Exchangeable Preferred Stock as stockholders of the Company shall cease (except
the right to receive Debentures and all accrued interest, if any, thereon), and
the Person or Persons entitled to receive the Debentures issuable upon exchange
shall be treated for all purposes as the registered holder or holders of such
Debentures as of the Exchange Date.

        11.    Amendment.
               ---------

        This Certificate of Designation shall not be amended, either directly or
indirectly, or through merger or consolidation with another entity, in any
manner that would alter or change the powers, preferences or special rights of
the Exchangeable Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority or more of the outstanding
Exchangeable Preferred Stock, voting separately as a class. Notwithstanding the
foregoing, this Certificate of Designation may be amended by the Board of
Directors in order to provide for the Series B Preferred Stock to have a
Liquidation Preference of $1,000 per share.

        12.    Exclusion of Other Rights.
               -------------------------

        Except as may otherwise be required by law, the shares of Exchangeable
Preferred Stock shall not have any voting powers, preferences and relative,
participating, optional or other special rights, other than those specifically
set forth in this resolution (as such resolution may be amended from time to
time) and in the Certificate of Incorporation. The shares of Exchangeable
Preferred Stock shall have no preemptive or subscription rights.

        13.    Headings of Subdivisions.
               ------------------------

        The headings of the various subdivisions hereof are for convenience of
reference only and shall not affect the interpretation of any of the provisions
hereof.

        14.    Severability of Provisions.
               --------------------------

        If any voting powers, preferences and relative, participating, optional
and other special rights of the Exchangeable Preferred Stock and qualifications,
limitations and restrictions thereof set forth in this resolution (as such
resolution may be amended from time to time) is invalid, unlawful or incapable
of being enforced by reason of any rule of law or public policy, all other
voting powers, preferences and relative, participating, optional and other
special rights of Exchangeable Preferred Stock and qualifications, limitations
and restrictions thereof set forth in this resolution (as so amended) which can
be given effect without the invalid, unlawful or unenforceable voting powers,
preferences and relative, participating, optional and other special rights of
Exchangeable Preferred Stock and qualifications, limitations and restrictions
thereof shall, nevertheless, remain in full force and effect, and no voting
powers, preferences and relative, participating, optional or other special
rights of Exchangeable Preferred Stock and qualifications, limitations and
restrictions thereof herein set forth shall be deemed dependent upon any other
such voting powers, preferences and relative, participating, optional or other
special rights of Exchangeable Preferred Stock and qualifications, limitations
and restrictions thereof unless so expressed herein.

        15.    Form of Exchangeable Preferred Stock.
               ------------------------------------

        (a) The Exchangeable Preferred Stock shall initially be issued in the
form of one or more Global Securities ("Global Securities"). The Global
Securities shall be deposited on the Issue Date with, or on behalf of, The
Depository Trust Company (the "Depositary") and registered in the name of Cede &
Co., as nominee of the Depositary (such nominee being referred to as the "Global
Security Holder").

        (b) So long as the Global Security Holder is the registered owner of any
Exchangeable Preferred Stock, the Global Security Holder will be considered the
sole holder under this Certificate of Designation of any shares of Exchangeable
Preferred Stock evidenced by the Global Security. Beneficial owners of shares of
Exchangeable Preferred Stock evidenced by the Global Security shall not be
considered the owners or holders thereof under this Certificate of Designation
for any purpose.

        (c) Payments in respect of the Liquidation Preference, dividends and
Liquidated Damages, if any, on any Exchangeable Preferred Stock registered in
the name of the Global Security Holder on the applicable record date shall be
payable by the Company to or at the direction of the Global Security Holder in
its capacity as the registered holder under this Certificate of Designation. The
Company may treat the persons in whose names Exchangeable Preferred Stock,
including the Global Security, are registered as the owners thereof for the
purpose of receiving such payments.

        (d) Any person having a beneficial interest in a Global Security may,
upon request to the Company, exchange such beneficial interest for Exchangeable
Preferred Stock in the form of registered definitive certificates (the
"Certificated Securities"). Upon any such issuance, the Company shall register
such Certificated Securities in the name of, and cause the same to be delivered
to, such person or persons (or the nominee of any thereof). If (i) the Company
notifies the holders in writing that the Depositary is no longer willing or able
to act as a depositary and the Company is unable to locate a qualified successor
within 90 days or (ii) the Company, at its option, notifies the holders in
writing that it elects to cause the issuance of Exchangeable Preferred Stock in
the form of Certificated Securities under this Certificate of Designation, then,
upon surrender by the Global Security Holder of its Global Security,
Exchangeable Preferred Stock in such form will be issued to each person that the
Global Security Holder and the Depositary identify as being the beneficial owner
of the related Exchangeable Preferred Stock.

        (e) Each Global Security shall bear a legend in substantially the
following form:

        "UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR A SECURITY IN
        DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE
        BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE
        DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY
        THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A
        NOMINEE OF SUCH SUCCESSOR DEPOSITARY. THE DEPOSITARY TRUST COMPANY SHALL
        ACT AS THE DEPOSITARY UNTIL A SUCCESSOR SHALL BE APPOINTED BY THE
        COMPANY AND THE TRANSFER AGENT. UNLESS THIS CERTIFICATE IS PRESENTED BY
        AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY TRUST COMPANY (55 WATER
        STREET, NEW YORK, NEW YORK) ("DTC"), TO THE ISSUER OR ITS AGENT FOR
        REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE
        ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY
        BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS
        MADE TO 

                                       31
<PAGE>
 
        CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED
        REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
        VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
        REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN."

        (f) The shares of Exchangeable Preferred Stock and the Debentures
issuable upon exchange thereof will bear a legend to the following effect,
unless the Company determines otherwise in compliance with applicable law:

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

SECTION 1.01 DEFINITIONS.

Indebtedness of any other Person existing at the time such other Person is

               "Affiliate" of any specified Person means any other Person

Person, shall mean the possession, directly or indirectly, of the power to
direct or cause the direction of the management or policies of such Person,
whether through the ownership of voting securities, by agreement or otherwise,

               "Attributable Debt" means, with respect to any Sale and Leaseback
Transaction, the present value at the time of determination (discounted at a
rate consistent with accounting guidelines, as determined in good faith by the
Company) of the payments during the remaining term of the lease (including any
period for which such lease has been extended or may, at the option of the
lessor, be extended) or until the earliest date on which the lessee may
terminate such lease without penalty or upon payment of a penalty (in which case
the rental payments shall include such penalty), after excluding all amounts
required to be paid on account of maintenance and repairs, insurance, taxes,
assessments, water, utilities and similar charges.

               "Beneficial Owner" means a beneficial owner as defined in Rules
13d-3 and 13d-5 under the Exchange Act (or any successor rules), including the
provision of such Rules that a Person shall be deemed to have beneficial
ownership of all securities that such Person has a right to acquire within 60
days; provided that a Person will not be deemed a beneficial owner of, or to own
beneficially, any securities if such beneficial ownership (1) arises solely as a
result of a revocable proxy delivered in response to a proxy or consent and (2)
is not also then reportable on Schedule 13D or Schedule 13G (or any successor
schedule) under the Exchange Act.

               "Board of Directors" means, unless otherwise specified, the Board

accordance with GAAP.

stock, (ii) in the case of an association or business entity, any and all
shares, interests, participations, rights or other equivalents (however
designated) of corporate stock and (iii) in the case of a partnership,
partnership interests (whether general or limited) and any other interest or
participation that confers on a Person the right to receive a share of the
profits and losses of, or distributions of assets of, such partnership.

               "Change of Control" means the occurrence of any of the following:
(i) the sale, lease, transfer, conveyance or other disposition, in one or a
series of related transactions, of all or substantially all of the assets of the

term is used in Section 13(d)(3) and 14(d)(2) of the Exchange Act), (ii) the
adoption of a plan relating to the liquidation or dissolution of the Company,
(iii) any Person or group (as defined above) is or becomes the Beneficial Owner,

               "Closing Price" on any Trading Day with respect to the per share
price of any shares of Capital Stock means the last reported sale price regular
way or, in case no such reported sale takes place on such day, the average of
the reported closing bid and asked prices regular way, in either case on the New
York Stock Exchange or, if such shares of Capital Stock are not listed or
admitted to trading on such exchange, on the principal national securities
exchange on which such shares are listed or admitted to trading or, if not
listed or admitted to trading on any national securities exchange, on the Nasdaq
National Market or, if such shares are not listed or admitted to trading on any
national securities exchange or quoted on Nasdaq National Market but the issuer
is a Foreign Issuer (as defined in Rule 3b- 4(b) under the Exchange Act) and the
principal securities exchange on which such shares are listed or admitted to
trading is a Designated Offshore Securities Market (as defined in Rule 902(a)
under the Securities Act), the average of the reported closing bid and asked
prices regular way on such principal exchange, or, if such shares are not listed
or admitted to trading on any national securities exchange or quoted on Nasdaq
National Market and the issuer and principal securities exchange do not meet
such requirements, the average of the closing bid and asked prices in the
over-the-counter market as furnished by any New York Stock Exchange member firm
that is selected from time to time by the Company for that purpose and is
reasonably acceptable to the Trustee.

               "Common Stock" of any Person means Capital Stock of such Person
that does not rank prior, as to the payment of dividends or as to the
distribution of assets upon any voluntary or involuntary liquidation,
dissolution or winding up of such Person, to shares of Capital Stock of any
other class of such Person.

               "Consolidated Cash Flow Leverage Ratio" with respect to any
Person means the ratio of the Consolidated Indebtedness of such Person to the
Consolidated EBITDA of such Person for the relevant period; provided, however,
that (1) if the Company or any Subsidiary of the Company has incurred any
Indebtedness (including Acquired Debt) or if the Company has issued any
Disqualified Stock or if any Subsidiary of the Company has issued any Preferred
Stock since the beginning of such period that remains outstanding on the date of
such determination or if the transaction giving rise to the need to calculate
the Consolidated Cash Flow Leverage Ratio is an incurrence of Indebtedness
(including Acquired Debt) or the issuance of Disqualified 

                                       2
<PAGE>
 
Stock by the Company, Consolidated EBITDA and Consolidated Indebtedness for such
period will be calculated after giving effect on a pro forma basis to (A) such
Indebtedness, Disqualified Stock or Preferred Stock, as applicable, as if such
Indebtedness had been incurred or such stock had been issued on the first day of
such period, (B) the discharge of any other Indebtedness repaid, repurchased,
defeased or otherwise discharged with the proceeds of such new Indebtedness or
sale of stock as if such discharge had occurred on the first day of such period,
and (C) the interest income realized by the Company or its Subsidiaries on the
proceeds of such Indebtedness or of such stock sale, to the extent not yet
applied at the date of determination, assuming such proceeds earned interest at
the rate in effect on the date of determination from the first day of such
period through such date of determination, (2) if since the beginning of such
period the Company or any Subsidiary of the Company has made any sale of assets
(including, without limitation, any Asset Sales or pursuant to any Sale and
Leaseback Transaction), Consolidated EBITDA for such period will be (A) reduced
by an amount equal to Consolidated EBITDA (if positive) directly attributable to
the assets which are the subject of such sale of assets for such period or (B)
increased by an amount equal to Consolidated EBITDA (if negative) directly
attributable thereto for such period and (3) if since the beginning of such
period the Company or any Subsidiary of the Company (by merger or otherwise) has
made an Investment in any Subsidiary of the Company (or any Person which becomes
a Subsidiary of the Company) or has made an acquisition of assets, including,
without limitation, any acquisition of assets occurring in connection with a
transaction causing a calculation of Consolidated EBITDA to be made hereunder,
which constitutes all or substantially all of an operating unit of a business,
Consolidated EBITDA for such period will be calculated after giving pro forma
effect thereto (including the incurrence of any Indebtedness (including Acquired
Debt)) as if such Investment or acquisition occurred on the first day of such
period. For purposes of this definition, whenever pro forma effect is to be
given to an acquisition of assets, the pro forma calculations will be determined
in good faith by a responsible financial or accounting Officer of the Company,
provided, however, that such Officer shall assume (i) the historical sales and
gross profit margins associated with such assets for any consecutive 12-month
period ended prior to the date of purchase (provided that the first month of
such 12-month period will be no more than 18 months prior to such date of
purchase) and (ii) other expenses as if such assets had been owned by the
Company since the first day of such period. If any Indebtedness (including,
without limitation, Acquired Debt) bears a floating rate of interest and is
being given pro forma effect, the interest on such Indebtedness will be
calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period.

               "Consolidated EBITDA" as of any date of determination means the
Consolidated Net Income for such period (but without giving effect to
adjustments, accruals, deductions or entries resulting from purchase accounting,
extraordinary losses or gains and any gains or losses from any Asset Sales),
plus the following to the extent deducted in calculating such Consolidated Net
Income: (i) provision for taxes based on income or profits of such Person and
its Subsidiaries for such period, (ii) Consolidated Interest Expense, (iii)
depreciation, amortization (including amortization of goodwill and other
intangibles) and other non-cash charges (excluding any such non-cash charge to
the extent that it represents an accrual of or reserve for cash charges in any
future period or amortization of a prepaid cash expense that was paid in a prior
period and excluding non-cash interest and dividend income) of such Person and
its Subsidiaries for such period, in each case, on a consolidated basis and
determined in accordance with GAAP. Notwithstanding the foregoing, the provision
for taxes on the income or profits of, and the depreciation, amortization,
interest expense and other non-cash charges of, a Subsidiary of the referent
Person shall be added to Consolidated Net Income to compute Consolidated EBITDA
only to the extent (and in the same proportion) that the Net Income of such
Subsidiary was included in calculating the Consolidated Net Income of such
Person and only if a corresponding amount would be permitted at the date of
determination to be dividended to the Company by such Subsidiary, or loaned to
the Company by any such Subsidiary, without prior approval (that has not been
obtained), pursuant to the terms of its charter and all agreements, instruments,
judgments, decrees, orders, statutes, rules and governmental regulations
applicable to that Subsidiary or its stockholders.

                                       3
<PAGE>
 
               "Consolidated Indebtedness" means, with respect to any Person, as
of any date of determination, the aggregate amount of Indebtedness of such
Person and its Subsidiaries as of such date calculated on a consolidated basis
in accordance with GAAP consistently applied.

               "Consolidated Interest Expense" means, for any Person, for any
period, the aggregate of the following for such Person for such period
determined on a consolidated basis in accordance with GAAP: (a) the amount of
interest in respect of Indebtedness (including amortization of original issue
discount, amortization of debt issuance costs, and non-cash interest payments on
any Indebtedness, the interest portion of any deferred payment obligation and
after taking into account the effect of elections made under any Interest Rate
Agreement, however denominated, with respect to such Indebtedness), (b) the
amount of Redeemable Dividends (to the extent not already included in
Indebtedness in determining Consolidated Interest Expense for the relevant
period) and (c) the interest component of rentals in respect of any Capital
Lease Obligation paid, in each case whether accrued or scheduled to be paid or
accrued by such Person during such period to the extent such amounts were
deducted in computing Consolidated Net Income, determined on a consolidated
basis in accordance with GAAP. For purposes of this definition, interest on a
Capital Lease Obligation shall be deemed to accrue at an interest rate
reasonably determined by such Person to be the rate of interest implicit in such
Capital Lease Obligation in accordance with GAAP consistently applied.

               "Consolidated Net Income" means, with respect to any Person for
any period, the aggregate of the Net Income of such Person and its Subsidiaries

SECTION 2.01.  FORM AND DATING.

         The Debentures and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto, the terms of which are
incorporated in and made a part of this Indenture. The Debentures may have
notations, legends or endorsements required by law, stock exchange rule or
usage. Each Debenture shall be dated the date of its authentication. The

                                       14
<PAGE>
 
integral multiples thereof; provided that in connection with the original
issuance of Debentures hereunder in exchange for shares of the Series A

after issuance of Debentures in denominations of $1,000 or less and/or integral
multiples thereof, in cash or in additional Debentures in denominations of less
than $1,000.

         The terms and provisions contained in the Debentures shall constitute,
and are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

         Debentures issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the text referred to in footnotes 1 and 2
thereto). Debentures issued in definitive form shall be substantially in the
form of Exhibit A attached hereto (but without including the text referred to in
footnotes 1 and 2 thereto). Each Global Debenture shall represent such of the
outstanding Debentures as shall be specified therein and each shall provide that
it shall represent the aggregate amount of outstanding Debentures from time to
time endorsed thereon and that the aggregate amount of outstanding Debentures
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Debenture to reflect the amount of any increase or decrease in the amount of
outstanding Debentures represented thereby shall be made by the Trustee or the
Debenture Custodian, at the direction of the Trustee, in accordance with
instructions given by the Holder thereof as required by Section 2.06 hereof.

SECTION 2.02.  EXECUTION AND AUTHENTICATION.

         Two Officers of the Company shall sign the Debentures for the Company
by manual or facsimile signature. The Company's seal shall be reproduced on the
Debentures and may be in facsimile form.

         If an Officer whose signature is on a Debenture no longer holds that
office at the time a Debenture is authenticated, the Debenture shall
nevertheless be valid. In addition, if a Person is not an Officer at the time a
Debenture is authenticated, but becomes an Officer on or prior to the delivery
of the Debenture, the Debenture shall nevertheless be valid.

         A Debenture shall not be valid until authenticated by the manual
signature of an authorized signatory of the Trustee. The signature of the
Trustee shall be conclusive evidence that the Debenture has been authenticated
under this Indenture.

         The Trustee shall, upon a written order of the Company signed by two
Officers of the Company, authenticate Debentures for original issue up to the
aggregate principal amount stated in paragraph 4 of the Debentures. The
aggregate principal amount of Debentures outstanding at any time may not exceed
such amount except as provided in Section 2.07 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate the Debentures. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Debentures 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 rights as an Agent to deal with the Company or an Affiliate of the Company.

SECTION 2.03.  REGISTRAR AND PAYING AGENT.

                                       15
<PAGE>
 
         The Company shall maintain an office or agency where Debentures may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Debentures may be presented for payment ("Paying Agent").
The Registrar shall keep a register of the Debentures and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrar and the
term "Paying Agent" includes any additional paying agent. The Company may change
any Paying Agent or Registrar without notice to any Holder. The Company shall
notify the Trustee and the Trustee shall notify the Holders of the Debentures in
writing of the name and address of any Agent not a party to this Indenture. If
the Company fails to appoint or maintain another entity as Registrar or Paying
Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may
act as Paying Agent or Registrar. The Company shall enter into an appropriate
agency agreement with any Agent not a party to this Indenture, which shall
incorporate the provisions of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the
Trustee shall act as such, and shall be entitled to appropriate compensation in
accordance with Section 7.07 hereof.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depository with respect to the Global Debentures.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Debenture Custodian with respect to the Global
Debentures. Except as otherwise specifically provided herein, (i) all references
in this Indenture to the Trustee shall be deemed to refer to the Trustee in its
capacity as Trustee and in its capacities as Registrar, Paying Agent and
Debenture Custodian and (ii) every provision of this Indenture relating to the
conduct of or affecting the liability of or offering protection, immunity or
indemnity to the Trustee shall be deemed to apply with the same force and effect
to the Trustee acting in its capacities as Paying Agent and Registrar.

SECTION 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money (or Debentures, if applicable), held by the
Paying Agent for the payment of principal, premium, if any, interest and
Liquidated Damages, if any, on the Debentures, and will notify the Trustee of
any default by the Company in making any such, premium, if any, payment. While
any such default continues, the Trustee may require a Paying Agent to pay all
money held by it to the Trustee. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee. Upon payment over to the
Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have
no further liability for the money. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money (or Debentures, if applicable), held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee shall serve as Paying Agent and Registrar for the
Debentures.

SECTION 2.05.  HOLDER 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
all Holders and shall otherwise comply with TIA ss. 312(a). If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and 

                                       16
<PAGE>
 
as of such date as the Trustee may reasonably require of the names and addresses
of the Holders of Debentures, including the aggregate principal amount of the
Debentures held by each such Holder, and the Company shall otherwise comply with
TIA (s)(s) 312(a).

SECTION 2.06.  TRANSFER AND EXCHANGE.

         (a) Transfer and Exchange of Definitive Debentures. When Definitive
Debentures are presented by a Holder to the Registrar with a request:

             (x) to register the transfer of the Definitive Debentures; or

                 amount of Definitive Debentures of other authorized

its requirements for such transactions are met; provided, however, that the

                          Rule 144A under the Securities Act or (2) pursuant to
                          an exemption from registration in accordance with Rule
                          144 under the Securities Act (and based on an opinion
                          of counsel if the Company so requests) or (3) pursuant

                          hereto); or

                      (C) if such beneficial interest is being transferred to an
                          institutional "accredited investor," within the
                          meaning of Rule 501(a)(1), (2), (3) or (7) under the

                      (D) if such beneficial interest is being transferred
                          pursuant to an exemption from registration in
                          accordance with Rule 904 under the Securities Act (and
                          based on an opinion of counsel if the Company so
                          requests), certifications to that effect from such
                          Holder (in substantially the form of Exhibit B
                          hereto); or

                      (E) if such beneficial interest is being transferred in
                          reliance on another exemption from the registration
                          requirements of the Securities Act (and based on an
                          opinion of counsel if the Company so requests), a
                          certification to that effect from such Holder (in
                          substantially the form of Exhibit B hereto);

                  the Trustee or the Debenture Custodian, at the direction of
                  the Trustee, shall, in accordance with the standing
                  instructions and procedures existing between the Depository
                  and the Debenture Custodian, cause the aggregate principal
                  amount of Global Debentures to be reduced accordingly and,
                  following such reduction, the Company shall execute and, upon
                  receipt of an authentication order in accordance with Section
                  2.02 hereof, the Trustee shall authenticate and deliver to the
                  transferee a Definitive Debenture in the appropriate principal
                  amount.

             (ii) Definitive Debentures issued in exchange for a beneficial
                  interest in a Global Debenture pursuant to this Section
                  2.06(d) shall be registered in such names and in such
                  authorized denominations as the Depository, pursuant to
                  instructions from its direct or indirect participants or
                  otherwise, shall instruct the Trustee. The Trustee shall
                  deliver in accordance with the standard procedures of the
                  Depository such Definitive Debentures to the Persons in whose
                  names such Debentures are so registered.

         (e) Restrictions on Transfer and Exchange of Global Debentures.
Notwithstanding any other provision of this Indenture (other than the provisions
set forth in subsection (f) of this Section 2.06), a Global Debenture may not be
transferred as a whole except by the Depository to a nominee of the Depository
or by a nominee of the Depository to the Depository or another nominee of the
Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository.

         (f) Authentication of Definitive Debentures in Absence of Depository.
             If at any time:

             (i)  the Depository for the Debentures notifies the Company that
                  the Depository is unwilling or unable to continue as
                  Depository for the Global Debentures and a successor
                  Depository for the Global Debentures is not appointed by the
                  Company within 120 days after delivery of such notice; or

             (ii) the Company, at its sole discretion, notifies the Trustee in
                  writing that it elects to cause the issuance of Definitive
                  Debentures under this Indenture,

then the Company shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 2.02 hereof, authenticate and
deliver, Definitive Debentures in an aggregate principal amount equal to the
principal amount of the Global Debentures in exchange for such Global Debentures
and registered in such names as the Depository shall instruct the Trustee or the
Company in writing.

         (g) Legends.

             (i)  Except for any Transfer Restricted Security sold or
                  transferred (including any Transfer Restricted Security
                  represented by a Global Debenture) as described in (ii) below,
                  each Debenture certificate evidencing Global Debentures and
                  Definitive Debentures (and all Debentures issued in exchange
                  therefor or substitution thereof) shall bear legends in
                  substantially the following form:

                  "THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS

                  (2) TO THE COMPANY, (3) PURSUANT TO AN EFFECTIVE REGISTRATION
                  STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN

                  PRIOR TO CLOSING OF ANY SALE, OF THE RESALE RESTRICTIONS SET
                  FORTH IN (A) ABOVE."

             (ii) Upon any sale or transfer of a Transfer Restricted Security
                  (including any Transfer Restricted Security represented by a
                  Global Debenture) pursuant to an effective registration
                  statement under the Securities Act, pursuant to Rule 144 under
                  the Securities Act or pursuant to an Opinion of Counsel
                  reasonably satisfactory to the Company and the Registrar that
                  no legend is required:

                  (A) in the case of any Transfer Restricted Security that is a
                      Definitive Debenture, the Registrar shall permit the
                      Holder thereof to exchange such Transfer Restricted
                      Security for a Definitive Debenture that does not bear the
                      legend set forth in (i) above and rescind any restriction
                      on the transfer of such Transfer Restricted Security; and

                  (B) in the case of any Transfer Restricted Security
                      represented by a Global Debenture, such Transfer
                      Restricted Security shall not be required to bear the
                      legend set forth in (i) above if all other interests in
                      such Global Debenture have been or are concurrently being
                      sold or transferred pursuant to Rule 144 under the
                      Securities Act or pursuant to an effective registration
                      statement under the Securities Act, but such Transfer
                      Restricted Security shall continue to be subject to the
                      provisions of Section 2.06(c) hereof; provided, however,
                      that with respect to any request for an exchange of a
                      Transfer Restricted Security that is represented by a
                      Global Debenture for a Definitive Debenture that does not
                      bear the legend set forth in (i) above, which request is
                      made in reliance upon Rule 144, the Holder thereof shall
                      certify in writing to the Registrar that such request is
                      being made pursuant to Rule 144 (such certification to be
                      substantially in the form of Exhibit B hereto).

            (iii) Notwithstanding the foregoing, upon consummation of the
                  Exchange Offer, the Company shall issue and, upon receipt of
                  an authentication order in accordance with Section 2.02
                  hereof, the Trustee shall authenticate New Exchange Debentures
                  in exchange for Exchange Debentures accepted for exchange in
                  the Exchange Offer, which New Exchange Debentures shall not
                  bear the legend set forth in (i) above, and the Registrar
                  shall rescind any restriction on the transfer of such
                  Debentures, in each case unless the Holder of such Exchange
                  Debentures is either (A) a broker-dealer, (B) a Person
                  participating in the distribution of the Exchange Debentures
                  or (C) a Person who is an affiliate (as defined in Rule 144A)
                  of the Company. The Company shall identify to the Trustee such
                  Holders of the Debentures in a written certification signed by
                  an Officer of the Company and, absent certification from the
                  Company to such effect, the Trustee shall assume that there
                  are no such Holders.

         (h) Cancellation and/or Adjustment of Global Debentures. At such time
as all beneficial interests in Global Debentures have been exchanged for
Definitive Debentures, redeemed, repurchased or cancelled, all Global Debentures
shall be returned to or retained and cancelled by the Trustee in accordance with
Section 

                                       21
<PAGE>
 
2.11 hereof. At any time prior to such cancellation, if any beneficial interest
in a Global Debenture is exchanged for Definitive Debentures, redeemed,
repurchased or cancelled, the principal amount of Debentures represented by such
Global Debenture shall be reduced accordingly and an endorsement shall be made
on such Global Debenture, by the Trustee or the Debentures Custodian, at the
direction of the Trustee, to reflect such reduction.

         (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
                      Company shall execute and the Trustee shall authenticate
                      Definitive Debentures and Global Debentures at the
                      Registrar's request.

                 (ii) No service charge shall be made to a Holder for any
                      registration of transfer or exchange, but the Company may
                      require payment of a sum sufficient to cover any transfer
                      tax or similar governmental charge payable in connection
                      therewith (other than any such transfer taxes or similar
                      governmental charge payable upon exchange or transfer
                      pursuant to Sections 3.07, 4.10, 4.15 and 9.05 hereto).

                (iii) Neither the Company nor the Registrar shall be required to
                      register the transfer of or exchange any Debenture
                      selected for redemption in whole or in part, except the
                      unredeemed portion of any Debenture being redeemed in
                      part.

                 (iv) All Definitive Debentures and Global Debentures issued
                      upon any registration of transfer or exchange of
                      Definitive Debentures or Global Debentures (including any
                      increase in the aggregate principal amount of the
                      Debentures represented by the Global Debenture pursuant to
                      subsection (b) above) shall be the valid obligations of
                      the Company, evidencing the same debt, and entitled to the
                      same benefits under this Indenture, as the Definitive
                      Debentures or Global Debentures surrendered upon such
                      registration of transfer or exchange.

                  (v) The Company shall not be required to issue Debentures and
                      the Registrar shall not be required to register the
                      transfer of or to exchange Debentures during a period
                      beginning at the opening of business 15 days before the
                      day of any selection of Debentures for redemption under
                      Section 3.02 hereof and ending at the close of business on
                      the day of selection, or to register the transfer of or to
                      exchange a Debenture between a record date and the next
                      succeeding interest payment date.

                 (vi) Prior to due presentment for the registration of a
                      transfer of any Debenture, the Trustee, any Agent and the
                      Company may deem and treat the Person in whose name any
                      Debenture is registered as the absolute owner of such
                      Debenture for the purpose of receiving payment of
                      principal of and interest on such Debentures, and neither
                      the Trustee, any Agent nor the Company shall be affected
                      by notice to the contrary.

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

SECTION 2.07.  REPLACEMENT DEBENTURES.

         If any mutilated Debenture is surrendered to the Trustee, or the
Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Debenture, the Company shall issue and the

                                       22
<PAGE>
 
Trustee, upon the written order of the Company signed by two Officers of the
Company, shall authenticate a replacement Debenture if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Debenture is
replaced. The Company may charge for its expenses in replacing a Debenture.

         Every replacement Debenture is an additional obligation of the Company
and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Debentures hereunder.

SECTION 2.08.  OUTSTANDING DEBENTURES.

         The Debentures outstanding at any time are all the Debentures
authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Debenture
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09 hereof, a Debenture does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Debenture.

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

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

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) segregates and holds in trust, in accordance with this
Indenture, on a redemption date or maturity date, money sufficient to pay all
principal, interest, premium and Liquidated Damages, if any, payable on that
date with respect to the Debentures (or the portion thereof to be redeemed or
maturing, as the case may be), then on and after that date such Debentures (or
portions thereof) shall be deemed to be no longer outstanding and shall cease to
accrue interest.

SECTION 2.09.  TREASURY DEBENTURES.

         In determining whether the Holders of the required principal amount of
Debentures have concurred in any direction, waiver or consent, Debentures owned
by the Company, or an Affiliate of the Company, shall be considered as though
not outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Debentures that a Responsible Officer of the Trustee knows are so owned shall be
so disregarded.

SECTION 2.10.  TEMPORARY DEBENTURES.

         Until definitive Debentures are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Debentures. Temporary
Debentures shall be substantially in the form of definitive Debentures but may
have variations that the Company and the Trustee consider appropriate for
temporary Debentures. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Debentures and deliver them in
exchange for temporary Debentures.

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

SECTION 2.11.  CANCELLATION.

         The Company at any time may deliver Debentures to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Debentures surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Debentures surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
shall destroy cancelled Debentures (subject to the record retention requirement
of the Exchange Act), unless the Company directs cancelled Debentures to be
returned to it. Certification of the destruction of all cancelled Debentures
shall be delivered to the Company for all certificates so destroyed. The Company
may not issue new Debentures to replace Debentures that it has redeemed, paid or
delivered to the Trustee for cancellation.

SECTION 2.12.  DEFAULTED INTEREST.

         If the Company defaults in a payment of interest on the Debentures, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, which date shall be at the earliest
practicable date but in all events at least five Business Days prior to the
payment date, in each case at the rate provided in the Debentures and in Section
4.01 hereof. The Company shall fix or cause to be fixed each such special record
date and payment date, provided that the Company shall fix or cause to be fixed
each such special record date as early as practicable prior to the payment date,
and the Company shall mail or cause to be mailed as early as practicable to each
Holder a notice that states the special record date, the related payment date
and the amount of defaulted interest to be paid.

SECTION 2.13.  RECORD DATE.

         The record date for purposes of determining the identity of Holders of
the Debentures entitled to vote or consent to any action by vote or consent
authorized or permitted under this Indenture shall be determined as provided for
in TIA ss. 316(c).

SECTION 2.14.  CUSIP NUMBER.

         The Company in issuing the Debentures may use a "CUSIP" number and, if
it does so, the Trustee shall use the CUSIP number 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
number printed in the notice or on the Debentures and that reliance may be
placed only on the other identification numbers printed on the Debentures. The
Company will promptly notify the Trustee of any change in the CUSIP number.

                       REDEMPTION AND CERTAIN REPURCHASES

SECTION 3.01.  NOTICES TO TRUSTEE.

         If the Company elects to redeem Debentures pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 45 days (unless a shorter period is acceptable to the Trustee) but not
more than 60 days before a redemption date, an Officers' Certificate setting
forth (i) the clause of this Indenture pursuant to which the redemption shall
occur, (ii) the redemption date, (iii) the principal amount of Debentures to be
redeemed and (iv) the redemption price.

                                       24

SECTION 3.02.  SELECTION OF DEBENTURES TO BE REDEEMED.

         If less than all of the Debentures are to be redeemed at any time,
except as provided in Section 3.09, the Trustee shall select the Debentures to
be redeemed or purchased in compliance with the requirements of the principal
national securities exchange, if any, on which the Debentures are listed, or, if
the Debentures are not so listed, on a pro rata basis, by lot or in accordance
with any other method the Trustee considers fair and appropriate (and in such
manner as complies with applicable legal and stock exchange requirements, if
any), provided that no Debentures with a principal amount of $1,000 or less
shall be redeemed or purchased in part. A new Debenture in principal amount
equal to the unredeemed or unpurchased portion shall be issued in the name of
the Holder thereof upon cancellation of the original Debenture. On and after the
redemption or purchase date, interest shall cease to accrue on the Debentures or
portions of them called for redemption or purchase. In the event of partial
redemption by lot, the particular Debentures to be redeemed shall be selected,
unless otherwise provided herein, not less than 30 nor more than 60 days prior
to the redemption date by the Trustee from the outstanding Debentures not
previously called for redemption.

         The Trustee shall promptly notify the Company in writing of the
Debentures selected for redemption and, in the case of any Debenture selected
for partial redemption, the principal amount thereof to be redeemed. Debentures
and portions of them selected shall be in amounts of $1,000 or whole multiples
of $1,000; except that if all of the Debentures of a Holder are to be redeemed,
the entire outstanding amount of Debentures held by such Holder, even if not a
multiple of $1,000, shall be redeemed. Except as provided in the preceding
sentence, provisions of this Indenture that apply to Debentures called for
redemption also apply to portions of Debentures called for redemption.

SECTION 3.03.  NOTICE OF REDEMPTION.

         Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Debentures are to be redeemed at its registered address (provided that in the
event of a redemption pursuant to Section 3.07(b) hereof arising out of a sale
of the Company's Capital Stock (other than Disqualified Stock) to a Strategic
Equity Investor, such notice shall not be mailed prior to the consummation of
such sale).

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

         (a) the redemption date;

         (b) the redemption price, separately stating the amount of Liquidated
     Damages to be paid in connection with redemption;

         (c) if any Debenture is being redeemed in part, the portion of the
     principal amount of such Debenture to be redeemed and that, after the
     redemption date upon surrender of such Debenture, a new Debenture or
     Debentures in principal amount equal to the unredeemed portion shall be
     issued upon cancellation of the original Debenture;

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

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

                                       25
<PAGE>
 
         (f) that, unless the Company defaults in making such redemption
     payment, interest on Debentures (or portions thereof) called for redemption
     ceases to accrue on and after the redemption date;

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

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

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

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

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

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

         At least one Business Day prior to the redemption date, the Company
shall deposit with the Trustee or with the Paying Agent (or, if the Company or a
Subsidiary is the Paying Agent, shall segregate and hold in trust) immediately
available funds sufficient to pay the redemption price of and accrued interest,
if any, on all Debentures to be redeemed on that date. The Trustee or the Paying
Agent shall promptly return to the Company any funds deposited with the Trustee
or the Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest and Liquidated Damages, if any, on,
all Debentures to be redeemed.

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the
Debentures or the portions of Debentures called for redemption (regardless of
whether certificates for such Debentures are actually surrendered). If a
Debenture is redeemed on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest and
Liquidated Damages, if any, shall be paid to the Person in whose name such
Debenture was registered at the close of business on such record date. If any
Debenture called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the
Debentures and in Section 4.01 hereof.

SECTION 3.06.  DEBENTURES REDEEMED IN PART.

         Upon surrender of a Debenture that is redeemed in part, the Company
shall issue, upon the Company's written request and the Trustee shall
authenticate for the Holder of the Debentures at the expense of the Company a
new Debenture equal in principal amount to the unredeemed portion of the
Debenture surrendered.

                                       26

SECTION 3.07.  OPTIONAL REDEMPTION.

         (a) Except as set forth in Section 3.07(b) below, the Debentures will
not be redeemable at the Company's option prior to March 31, 2002. Thereafter,
the Debentures will be subject to redemption at the option of the Company, in
whole or in part, upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning
on March 31 of the years indicated below:

Year                                                        Percentage
- ----                                                        ----------
2002.....................................................     106.75%
2003.....................................................     105.40%
2004.....................................................     104.05%
2005.....................................................     102.70%
2006.....................................................     101.35%
2007 and thereafter......................................     100.00%

        (b) Notwithstanding the provisions of Section 3.07(a) above, prior to
March 31, 2000, the Company may, on any one or more occasions, use the net
proceeds of one or more underwritten public offerings of its Common Stock or
from the sale of its Capital Stock (other than Disqualified Stock) to a
Strategic Investor in a single transaction or series of related transactions for
an aggregate purchase price equal to or exceeding $50.0 million, to redeem up to
a maximum of 35% of the aggregate principal amount of the Debentures originally
issued from the net cash proceeds of such sale or offering (but only to the
extent such proceeds consist of cash or readily marketable cash equivalents) at
a redemption price equal to 113 1/2% of the principal amount thereof with
respect to the Debentures to be redeemed on the redemption date, provided that
at least 65% of the aggregate principal amount of the Debentures originally
issued remains outstanding immediately after the occurrence of such redemption
and that such redemption occurs within 90 days of the date of the closing of
such sale.

        (c) Any redemption pursuant to this Section 3.07 shall be made pursuant
to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 3.08.  MANDATORY REDEMPTION.

         Except as set forth under Sections 3.09 and 4.15 hereof, the Company
shall not be required to make mandatory redemption or sinking fund payments with
respect to the Debentures.

SECTION 3.09.  OFFER TO PURCHASE WITH EXCESS ASSET SALE PROCEEDS.

         If at any time the cumulative amount of Excess Proceeds that have not
been applied in accordance with this Section 3.09 exceeds $5.0 million, the
Company shall, within 30 days thereafter, make an offer to all Holders of
Debentures and Holders of Pari Passu Notes (an "Excess Proceeds Offer" or "Asset
Sale Offer"), to purchase the maximum principal amount of Debentures and Pari
Passu Notes that may be purchased out of such Excess Proceeds, at an offer price
in cash in an amount equal to 100% of the outstanding principal amount of the
Debentures and the Pari Passu Notes, plus accrued and unpaid interest thereon
and Liquidated 

                                       27
<PAGE>
 
Damages, if any, to the date fixed for the closing of such offer, in accordance
with the procedures specified below.

         The Excess Proceeds Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Company shall purchase the maximum principal amount of Debentures
and Pari Passu Notes that may be purchased with such Excess Proceeds (or such
pro rata portion based upon the principal amount of the Debentures and Pari
Passu Notes tendered, if the principal amount of Debentures and Pari Passu Notes
tendered is in excess of the Excess Proceeds) (which maximum principal amount of
Debentures shall be the "Offer Amount") or, if less than the Offer Amount has
been tendered, all Debentures and Pari Passu Notes tendered in response to the
Excess Proceeds Offer, subject to the provisions of Section 4.10 hereof.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued interest on the Debentures
shall be paid to the Person in whose name a Debenture is registered at the close
of business on such record date, and no additional interest shall be payable to
Holders who tender Debentures pursuant to the Excess Proceeds Offer on the
portion of the tendered Debentures purchased pursuant to the Excess Proceeds
Offer.

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

             (a) that the Excess Proceeds Offer is being made pursuant to
     Sections 3.09 and 4.10 hereof and the length of time the Excess Proceeds
     Offer shall remain open;

             (b) the Offer Amount, the purchase price and the Purchase Date;

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

             (d) that any Debenture or portion thereof accepted for payment
     pursuant to the Excess Proceeds Offer shall cease to accrue interest after
     the Purchase Date;

             (e) that Holders electing to have a Debenture or portion thereof
     purchased pursuant to any Excess Proceeds Offer shall be required to
     surrender the Debenture, with the form entitled "Option of Holder to Elect
     Purchase" on the reverse of the Debenture completed, to the Company, a
     depositary, if appointed by the Company, or a Paying Agent at the address
     specified in the notice at least three Business Days before the Purchase
     Date;

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

             (g) that, if the aggregate principal amount of Debentures and Pari
     Passu Notes tendered by Holders of such notes exceeds the Offer Amount, the
     Trustee shall select the Debentures to be purchased 

                                       28
<PAGE>
 
     on a pro rata basis as described above (with such adjustments as may be
     deemed appropriate by the Trustee so that only Debentures in denominations
     of $1,000, or integral multiples thereof, shall be purchased); and

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

         On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis (as described above) to the
extent necessary, the Offer Amount of Debentures or portions thereof tendered
pursuant to the Excess Proceeds Offer, or if less than the Offer Amount has been
tendered, all Debentures or portion thereof tendered, and deliver to the Trustee
an Officers' Certificate stating that such Debentures or portions thereof were
accepted for payment by the Company in accordance with the terms of this Section
3.09. The Company, Depository or Paying Agent, as the case may be, shall
promptly (but in any case not later than five days after the Purchase Date) mail
or deliver to each tendering Holder an amount equal to the purchase price of the
Debenture or portion thereof tendered by such Holder and accepted by the Company
for purchase, and the Company shall promptly issue a new Debenture, and the
Trustee shall authenticate and mail or deliver such new Debenture to such Holder
equal in principal amount to any unpurchased portion of the Debenture
surrendered. Any Debenture not so accepted shall be promptly mailed or delivered
by the Company to the Holder thereof. The Company shall publicly announce the
results of the Excess Proceeds Offer on the Purchase Date. In the event that the
aggregate amount of Excess Proceeds exceeds the aggregate principal amount of
Debentures, Pari Passu Notes or portion thereof surrendered by Holders of such
notes pursuant to an Excess Proceeds Offer, the Company may use the remaining
Excess Proceeds for general purposes. Upon completion of an Excess Proceeds
Offer, the amount of Excess Proceeds shall be deemed to be reset at zero.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof. No repurchase of Debentures under this
Section 3.9 shall be deemed to be a redemption of Debentures.

SECTION 4.01.  PAYMENT OF DEBENTURES.

         The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Debentures on the dates and in the manner provided in
the Debentures and this Indenture. Principal, premium, if any, and interest
shall be considered paid on the date due if the Paying Agent, if other than the
Company, holds as of the due date money deposited by, or on behalf of, the
Company in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due. The Company shall pay all
Liquidated Damages, if any, in the same manner on the dates and in the amounts
set forth in the Registration Rights Agreement. If any Liquidated Damages become
payable, the Company shall not later than three Business Days prior to the date
that any payment of Liquidated Damages is due (i) deliver an Officers'
Certificate to the Trustee setting forth the amount of Liquidated Damages
payable to Holders and (ii) instruct the Paying Agent to pay such amount of
Liquidated Damages to Holders entitled to receive such Liquidated Damages.

                                       29

         The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
the then applicable interest rate on the Debentures to the extent lawful until
such overdue principal is paid; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace period)
at the same rate to the extent lawful until such overdue installments of
interest and Liquidated Damages are paid.

         The term "Bankruptcy Law" means title 11, U.S. Code or any similar
federal or state law for the relief of debtors.

SECTION 4.02.  MAINTENANCE OF OFFICE OR AGENCY.

         The Company shall maintain an office or agency (which may be an office
of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where
Debentures may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Debentures and this
Indenture may be served. The Company shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

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

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

SECTION 4.03.  REPORTS.

         (a) So long as any of the Debentures remain outstanding, the Company
shall cause copies of all quarterly and annual financial reports and of the
information, documents, and other reports (or copies of such portions of any of
the foregoing as the SEC may by rules and regulations prescribe) which the
Company is required to file with the SEC pursuant to Section 13(a) or 15(d) of
the Exchange Act ("SEC Reports") to be filed with the Trustee and mailed to the
Holders at their addresses appearing in the register of Debentures maintained by
the Registrar, in each case, within 15 days of filing with the SEC. If the
Company is not subject to the requirements of Section 13(a) or 15(d) of the
Exchange Act or shall cease to be required by the SEC to file SEC Reports, the
Company shall nevertheless continue to cause SEC Reports, comparable to those
which it would be required to file pursuant to Section 13(a) or 15(d) of the
Exchange Act if it were subject to the requirements of either such Section, to
be so filed with the SEC for public availability (unless the SEC will not accept
such a filing) and with the Trustee and mailed to the Holders, in each case,
within the same time periods as would have applied (including under the
preceding sentence) had the Company been subject to the requirements of Section
13(a) or 15(d) of the Exchange Act. The Company shall make all such information
available to investors who request it in writing. The Company shall also comply
with the provisions of TIA (s)(s) 314(a).

shall furnish to the Holders of the Debentures and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Act.

         (c) The Company shall provide the Trustee with a sufficient number of
copies of all SEC Reports that the Trustee may be required to deliver to the
Holders of the Debentures under this Section 4.03.

SECTION 4.04.  COMPLIANCE CERTIFICATE.

         (a) The Company shall deliver to the Trustee, within 90 days after the
end of each fiscal year of the Company, an Officers' Certificate stating that
(i) a review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has (x) kept, observed,
performed and fulfilled, and (y) caused each of its Subsidiaries to keep,
observe, perform and fulfill, its obligations under this Indenture, and (ii) as
to each such Officer signing such certificate, that to the best of his or her
knowledge (A) the Company has kept, observed, performed and fulfilled, and has
caused each of its Subsidiaries to keep, observe, perform and fulfill, each and
every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture to be performed or observed by it (or, if a Default or Event of
Default shall have occurred, describing all such Defaults or Events of Default
of which he or she may have knowledge and what action each is taking or proposes
to take with respect thereto) and (B) 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 Debentures is prohibited or if such event has occurred,
a description of the event and what action each is taking or proposes to take

         (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03 above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention which would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 of this Indenture or, if any such
violation has occurred, specifying the nature and period of existence thereof,
it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such
violation.

         (c) The Company shall, so long as any of the Debentures 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, Event of Default or default and what action the Company is taking or
proposes to take with respect thereto.

         (d) The Company shall deliver to the Trustee an Officers' Certificate
as required by, and in accordance with, Section 4.07(f) hereof.

SECTION 4.05.  TAXES.

         The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies,
except as contested in good faith and by appropriate proceedings or where the
failure to effect such payment is not adverse in any material respect to the
Holders of the Debentures.

SECTION 4.06.  STAY, EXTENSION AND USURY LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it shall not at any time insist upon, plead, or in any manner whatsoever claim

enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has

SECTION 4.07.  RESTRICTED PAYMENTS.

         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly:

             (i) declare or pay any dividend or make any distribution on account
         of any Equity Interests of the Company or any of its Subsidiaries other

         Subsidiary;

             (ii) purchase, redeem, defease, retire or otherwise acquire for
         value ("Retire" and correlatively, a "Retirement") any Equity Interests
         of the Company or any of its Subsidiaries or other Affiliate of the
         Company (other than any such Equity Interests owned by the Company or
         any Subsidiary);

            (iii) Retire for value any Indebtedness of (A) the Company that is
         subordinate in right of payment to the Debentures or (B) any
         Subsidiary, except, with respect to clause (i)(A) or (i)(B) above, at
         final maturity or in accordance with the mandatory redemption or
         repayment provisions set forth in the original documentation governing
         such Indebtedness; or

             (iv) make any Restricted Investment (all such payments and other
         actions set forth in clauses (i) through (iv) above being collectively
         referred to as "Restricted Payments"), unless, at the time of such
         Restricted Payment:

                  (a) no Default or Event of Default has occurred and is
             continuing or would occur as a consequence thereof;

                  (b) after giving effect to such Restricted Payment on a pro
             forma basis as if such Restricted Payment had been made at the
             beginning of the applicable four-quarter period, the Company could
             incur at least $1.00 of additional Indebtedness pursuant to the
             Consolidated Cash Flow Leverage Ratio test set forth in Section
             4.09(a) hereof; and

                  (c) such Restricted Payment, together with the aggregate of
             all other Restricted Payments made by the Company and its
             Subsidiaries after the Issue Date (including any Restricted
             Payments made pursuant to clauses (i), (v) and (vi) of the next
             paragraph), is less than the sum of

                          (w) 50% of the Consolidated Net Income of the Company
                      for the period (taken as one accounting period) from the
                      beginning of the first fiscal quarter

                      commencing after the Issue Date to the end of the
                      Company's most recently ended fiscal quarter for which
                      internal financial statements are available at the time of
                      such Restricted Payment (or, if such Consolidated Net
                      Income for such period is a deficit, less 100% of such
                      deficit), plus

                          (x) 100% of the aggregate net cash proceeds received
                      by the Company from the issue or sale of Equity Interests
                      of the Company or of debt securities or Disqualified Stock
                      of the Company that have been converted into such Equity
                      Interests (other than Equity Interests (or convertible
                      debt securities) sold to a Subsidiary of the Company and
                      other than Disqualified Stock or debt securities that have
                      been converted into Disqualified Stock) after the Issue
                      Date (other than any such Equity Interests, the proceeds
                      of which were used as set forth in clause (ii) below, plus

                      (y) 100% of the sum of, without duplication, (1) aggregate
                      dividends or distributions received by the Company or any
                      Subsidiary from any Joint Venture (other than dividends or
                      distributions to pay any obligations of such Joint Venture
                      to Persons other than the Company or any Subsidiary, such
                      as income taxes), with non-cash distributions to be valued
                      at the lower of book value or fair market value as
                      determined by the Board of Directors, (2) the amount of
                      the principal and interest payments received since the
                      Issue Date by the Company or any Subsidiary from any Joint
                      Venture and (3) the net proceeds from the sale of an
                      Investment in a Joint Venture received by the Company or
                      any Subsidiary; provided that there is no obligation to
                      return any such amounts to the Joint Venture, and
                      excluding any such dividend, distribution, interest
                      payment or net proceeds that constitutes a return of
                      capital invested pursuant to clause (vi) of the next
                      succeeding paragraph, plus

                      (z) $10.0 million.

         The foregoing provisions in Section 4.07(a) shall not prohibit:

             (i) the payment of any dividend within 60 days after the date of
         declaration thereof, if at such date of declaration such payment would
         have complied with the provisions of this Indenture;

             (ii) the Retirement of (A) any Equity Interests of the Company or
         any Subsidiary of the Company, (B) Indebtedness of the Company that is
         subordinate to the Debentures or (C) Indebtedness of a Subsidiary of
         the Company, in exchange for, or out of the proceeds of the
         substantially concurrent sale (other than to a Subsidiary of the
         Company) of, Equity Interests of the Company (other than Disqualified
         Stock);

            (iii) the Retirement of any Indebtedness of the Company subordinated
         in right of payment to the Debentures in exchange for, or out of the
         proceeds of the substantially concurrent incurrence of Indebtedness of
         the Company (other than Indebtedness to a Subsidiary of the Company),
         but only to the extent that such new Indebtedness is permitted under
         Section 4.09 hereof and (1) is subordinated in right of payment to the
         Debentures at least to the same extent as, (2) has a Weighted Average
         Life to Maturity at least as long as, and (3) has no scheduled
         principal payments due in any amount earlier than, any equivalent
         amount of principal under the Indebtedness so Retired;

             (iv) the Retirement of any Indebtedness of a Subsidiary of the
         Company in exchange for, or out of the proceeds of the substantially
         concurrent incurrence of Indebtedness of the Company or any Subsidiary
         but only to the extent that such incurrence is permitted under Section
         4.09 hereof and only to the extent that such Indebtedness (1) is not
         secured by any assets of the Company or any 

                                       33
<PAGE>
 
         Subsidiary to a greater extent than the Retired Indebtedness was so
         secured, (2) has a Weighted Average Life to Maturity at least as long
         as the Retired Indebtedness and (3) if such Retired Indebtedness was an
         obligation of the Company, is pari passu or subordinated in right of
         payment to the Debentures at least to the same extent as the Retired
         Indebtedness;

             (v) the Retirement of any Equity Interests of the Company or any
         Subsidiary of the Company held by any member of the Company's (or any
         of its Subsidiaries') management pursuant to any management equity
         subscription agreement or stock option agreement; provided that the
         aggregate price paid for all such repurchased, redeemed, acquired or
         retired Equity Interests shall not exceed $1.0 million in any
         twelve-month period plus the aggregate cash proceeds received by the
         Company during such twelve-month period from any reissuance of Equity
         Interests by the Company to members of management of the Company and
         its Subsidiaries; and

             (vi) Investments in any Joint Venture; provided that at the time
         any such Investment is made, such Investment shall not cause the
         aggregate amount of Investments at any one time outstanding under this
         clause (vi) to exceed 5% of the Total Common Equity of the Company;

provided, however, that at the time of, and after giving effect to, any
Restricted Payment permitted under clauses (i), (ii), (iii), (iv), (v) and (vi),
no Default or Event of Default shall have occurred and be continuing.

     A Permitted Investment that ceases to be a Permitted Investment pursuant to
the definition thereof set forth in Section 1.01 hereof, shall become a
Restricted Investment, deemed to have been made on the date that it ceases to be
a Permitted Investment.

     The Board of Directors may designate any Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default or an Event of Default
pursuant to Article 6 hereof. For purposes of making such determination, all
outstanding Investments by the Company and its Subsidiaries (except to the
extent repaid in cash) in such Subsidiary so designated shall be deemed to be
Restricted Payments at the time of such designation and shall reduce the amount
available for Restricted Payments under the first paragraph of this Section
4.07. All such outstanding Investments will be deemed to constitute Investments
in an amount equal to the greatest of (x) the net book value of such Investments
at the time of such designation, (y) the fair market value of such Investments
at the time of such designation and (z) the original fair market value of such
Investments at the time they were made. Such designation will only be permitted
if such Restricted Payment would be permitted at such time.

     The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Subsidiary of the Company of
any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (i) such Indebtedness is permitted under
Section 4.09 hereof and (ii) no Default or Event of Default pursuant to Article
6 hereof would be in existence following such designation.

     Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by Section 4.09 were computed, which calculations may be based upon the
Company's latest available financial statements.

SECTION 4.08.  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

                                       34
<PAGE>
 
         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create or otherwise cause or become effective any
consensual encumbrance or restriction on the ability of any Subsidiary to:

             (i) pay dividends or make any other distributions to the Company or
         any of its Subsidiaries on its Capital Stock or with respect to any
         other interest or participation in, or measured by, its profits, or pay
         any Indebtedness owed to the Company or any of its Subsidiaries;

             (ii) make loans or advances to the Company or any of its
         Subsidiaries; or

            (iii) transfer any of its properties or assets to the Company or any
         of its Subsidiaries;

except for such encumbrances or restrictions existing as of the Issue Date or
under or by reason of:

             (a) Existing Indebtedness;

             (b) applicable law;

             (c) any instrument governing Acquired Debt as in effect at the time
         of acquisition (except to the extent such Indebtedness was incurred in
         connection with, or in contemplation of, such acquisition), which
         encumbrance or restriction is not applicable to any Person, or the
         properties or assets of any Person, other than the Person, or the
         property or assets of the Person, so acquired;

             (d) by reason of customary non-assignment provisions in leases
         entered into in the ordinary course of business and consistent with
         past practices;

             (e) Indebtedness in respect of a Permitted Refinancing, provided
         that the restrictions contained in the agreements governing such
         Refinancing Indebtedness are not materially more restrictive than those
         contained in the agreements governing the Indebtedness being
         refinanced;

             (f) with respect to clause (iii) above, purchase money obligations
         for property acquired in the ordinary course of business, Vendor
         Indebtedness incurred in connection with the purchase or lease of
         Telecommunications Related Assets or performance bonds or similar
         security for performance which liens securing such obligations do not
         cover any asset other than the asset acquired or, in the case of
         performance bonds or similar security for performance, the assets
         associated with the Company's performance;

             (g) Indebtedness incurred under Section 4.09(a) hereof;

             (h) this Indenture, the Series A Preferred Stock and the
Debentures; or

             (i) in the case of clauses (a), (c), (e), (g) and (h) above, any
             amendments, modifications, restatements, renewals, increases,
             supplements, refundings, replacements or refinancings thereof;
             provided that such amendments, modifications, restatements,
             renewals, increases, supplements, refundings, replacements or
             refinancings are not materially more restrictive with respect to
             such dividend and other payment restrictions than those contained
             in such instruments as in effect on the date of their incurrence
             or, if later, the Issue Date.

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

                                       35
<PAGE>
 
     (i) The Company and its Subsidiaries shall not, directly or indirectly,
create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable for the payment of (collectively, "incur" and, correlatively,
"incurred" and "incurrence") any Indebtedness (including, without limitation,
Acquired Debt), and

     (ii) the Company and its Subsidiaries shall not issue any Disqualified
Stock, provided, however, that the Company and/or any of its Subsidiaries may
incur Indebtedness (including, without limitation, Acquired Debt) or issue
shares of Disqualified Stock if, after giving effect to the incurrence of such
Indebtedness or the issuance of such Disqualified Stock, the Consolidated Cash
Flow Leverage Ratio for the Company's most recently ended four full fiscal
quarters for which internal financial statements are available immediately
preceding the date of such incurrence or issuance (A) does not exceed 5.5 to 1
if such incurrence or issuance occurs on or prior to June 1, 1999 and (B) does
not exceed 5.0 to 1 if such occurrence or issuance occurs after June 1, 1999, in
each case, determined on a pro forma basis (including a pro forma application of
the net proceeds therefrom), as if the additional Indebtedness had been
incurred, or the Disqualified Stock had been issued, as the case may be, at the
beginning of such four-quarter period. If the Company incurs any Indebtedness or
issues or redeems any Preferred Stock subsequent to the commencement of the
period for which such ratio is being calculated but prior to the event for which
the calculation of the ratio is made, then the ratio will be calculated giving
pro forma effect to any such incurrence of Indebtedness, or such issuance or
redemption of Preferred Stock, as if the same had occurred at the beginning of
the applicable period. In making such calculation on a pro forma basis, interest
attributable to Indebtedness bearing a floating interest rate shall be computed
as if the rate in effect on the date of computation had been the applicable rate
for the entire period.

     The foregoing limitation shall not apply to (with each exception to be
given independent effect):

         (a) the incurrence by the Company and/or any of its Subsidiaries of
         Indebtedness under the Credit Facility in an aggregate principal amount
         at any one time outstanding (with letters of credit being deemed to
         have a principal amount equal to the maximum potential liability of the
         Company and/or any of its Subsidiaries thereunder) not to exceed $75.0
         million in the aggregate at any one time outstanding, less the
         aggregate amount of all Net Proceeds of Asset Sales applied to
         permanently reduce the commitments with respect to such Indebtedness
         pursuant to Section 4.10 hereof;

         (b) the incurrence by the Company and/or any of its Subsidiaries of
         Vendor Indebtedness, provided that the aggregate amount of such Vendor
         Indebtedness incurred does not exceed 80% of the total cost of the
         Telecommunications Related Assets financed therewith (or 100% of the
         total cost of the Telecommunications Related Assets financed therewith
         if such Vendor Indebtedness was extended for the purchase of tangible
         physical assets and was so financed by the vendor thereof or an
         affiliate of such vendor);

         (c) the incurrence by the Company and/or any of its Subsidiaries of the
         Existing Indebtedness, including the Existing Senior Notes;

         (d) the incurrence by the Company and/or any of its Subsidiaries of
Indebtedness in an aggregate amount not to exceed $25.0 million at any one time
outstanding;

         (e) the incurrence by the Company of Indebtedness, but only to the
         extent that such Indebtedness is expressly subordinate to the payment
         in full of all Obligations with respect to the Existing Senior Notes
         and are not senior in right of payment of the Debentures and has a
         final maturity no earlier than, and a Weighted Average Life to Maturity
         equal to or greater than, the final maturity and 

                                       36
<PAGE>
 
         Weighted Average Life to Maturity, respectively, of the Debentures, in
         an aggregate principal amount not to exceed 2.0 times the net cash
         proceeds received by the Company after May 14, 1996 from the issuance
         and sale of Equity Interests of the Company plus the fair market value
         of Equity Interests (other than Disqualified Stock) issued in
         connection with any acquisition of any Telecommunications Business;

         (f) the incurrence (a "Permitted Refinancing") by the Company and/or
         any of its Subsidiaries of Indebtedness issued in exchange for, or the
         proceeds of which are used to refinance, replace, refund or defease
         ("Refinance" and correlatively, "Refinanced" and "Refinancing")
         Indebtedness, other than Indebtedness incurred pursuant to clause (a)
         above, but only to the extent that:

                      (1) the net proceeds of such Refinancing Indebtedness
             shall not exceed the principal amount of and premium, if any, and
             accrued interest on the Indebtedness so Refinanced (or if such
             Indebtedness was issued at an original issue discount, the original
             issue price plus amortization of the original issue discount at the
             time of the repayment of such Indebtedness) plus the fees, expenses
             and costs of such Refinancing and reasonable prepayment premiums,
             if any, in connection therewith;

                      (2) the Refinancing Indebtedness shall have a final
             maturity no earlier than, and a Weighted Average Life to Maturity
             equal to or greater than, the final maturity and Weighted Average
             Life to Maturity of the Indebtedness being Refinanced; and

                      (3) if the Indebtedness being Refinanced is subordinated
             in right of payment to the Debentures, the Refinancing Indebtedness
             shall be subordinated in right of payment to the Debentures on
             terms at least as favorable to the Holders of Debentures as those
             contained in the documentation governing the Indebtedness being so
             Refinanced;

         (g) the incurrence by the Company or any of its Subsidiaries of
         intercompany Indebtedness between or among the Company and any of its
         Subsidiaries; and

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

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

SECTION 4.10.  ASSET SALES.

         (a) The Company shall not, and shall not permit any of its Subsidiaries
to, whether in a single transaction or a series of related transactions
occurring within any twelve-month period,

             (i) sell, lease, convey, dispose or otherwise transfer any assets
         (including by way of a Sale and Leaseback Transaction) (other than
         sales, leases, conveyances, dispositions or other transfers 

                                       37

         (A) in the ordinary course of business, (B) to the Company by any
         Subsidiary of the Company or from the Company to any Subsidiary of the
         Company, (C) that constitute a Restricted Payment, Investment or
         dividend or distribution permitted under Section 4.07 hereof or (D)
         that constitute the disposition of all or substantially all of the
         assets of the Company pursuant to Section 5.01 hereof) or

             (ii) issue or sell Equity Interests in any of its Subsidiaries
         (other than an issuance or sale of Equity Interests of any such
         Subsidiary to the Company or a Subsidiary),

if, in the case of either (i) or (ii) above, in a single transaction or a series
of related transactions occurring within any twelve-month period, such assets or
securities

             (x) have a Fair Market Value in excess of $2.0 million or

             (y) are sold or otherwise disposed of for net proceeds in excess of
         $2.0 million (each of the foregoing, an "Asset Sale"), unless:

             (a) no Default or Event of Default exists or would occur as a
         result thereof;

             (b) the Company, or such Subsidiary, as the case may be, receives
         consideration at the time of such Asset Sale at least equal to the Fair
         Market Value (evidenced by a resolution of the Board of Directors of
         the Company set forth in an Officers' Certificate delivered to the
         Trustee), of the assets or securities issued or sold or otherwise
         disposed of; and

             (c) at least 85% of the consideration therefor received by the
         Company or such Subsidiary is in the form of cash, provided, however,
         that (A) the amount of (x) any liabilities (as shown on the Company's
         or such Subsidiary's most recent balance sheet or in the notes
         thereto), of the Company or any Subsidiary of the Company (other than
         liabilities that are by their terms subordinated to the Debentures)
         that are assumed by the transferee of any such assets and (y) any
         notes, obligations or other securities received by the Company or any
         such Subsidiary from such transferee that are immediately converted by
         the Company or such Subsidiary into cash, shall be deemed to be cash
         (to the extent of the cash received in the case of subclause (y)) for
         purposes of this clause (c); and (B) an amount equal to the Fair Market
         Value (determined as set forth in clause (b) above) of (1)
         Telecommunications Related Assets received by the Company or any such
         Subsidiary from the transferee that will be used by the Company or any
         such Subsidiary in the operation of a Telecommunications Business in
         the United States and (2) the Voting Stock of any Person engaged in the
         Telecommunications Business in the United States received by the
         Company or any such Subsidiary (provided that such Voting Stock is
         converted to cash within 270 days or such Person concurrently becomes
         or is a Subsidiary of the Company) shall be deemed to be cash for
         purposes of this clause (c).

The foregoing provisions shall not apply to a sale, lease, conveyance or other
disposition of all or substantially all of the assets of the Company, which
shall be governed by Article 5 hereof.

         Within 270 days after the receipt of net proceeds of any Asset Sale,
the Company (or such Subsidiary, as the case may be) may apply the Net Proceeds
from such Asset Sale to (i) permanently reduce the amounts permitted to be
borrowed by the Company under the terms of any of its Senior Debt (including the
Existing Senior Notes) or (ii) the purchase of Telecommunications Related Assets
or Voting Stock of any Person engaged in the Telecommunications Business in the
United States (provided that such Person concurrently becomes a Subsidiary of
the Company). Any Net Proceeds from any Asset Sales that are not 

                                       38
<PAGE>
 
so applied or invested, shall constitute "Excess Proceeds." When the aggregate
amount of Excess Proceeds exceeds $5.0 million, the Company shall be required to
make an Asset Sale Offer in accordance with the terms of Section 3.09 hereof.
Notwithstanding the foregoing, the Company shall have no obligation to make an
Asset Sale Offer unless the Existing Senior Notes outstanding, if any, have
matured or are no longer outstanding.

SECTION 4.11.  TRANSACTIONS WITH AFFILIATES.

         The Company shall not, and shall not permit any of its Subsidiaries to,
sell, lease, transfer or otherwise dispose of any of their respective properties
or assets to, or purchase any property or assets from, or enter into any
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless:

      (i) such Affiliate Transaction is on terms that are no less favorable to
the Company or the relevant Subsidiary than those that would have been obtained
in a comparable transaction by the Company or such Subsidiary with an unrelated
Person;

     (ii) such Affiliate Transaction is approved by a majority of the
disinterested directors of the Board of Directors; and

     (iii) the Company delivers to the Trustee, with respect to any Affiliate
Transaction involving aggregate payments in excess of $1.0 million, a resolution
of a committee of independent directors of the Company set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with clauses (i)
and (ii) above;

provided that

         (a) transactions pursuant to any employment, stock option or stock
     purchase agreement entered into by the Company or any of its Subsidiaries,
     or any grant of stock, in the ordinary course of business that are approved
     by the Board of Directors,

         (b) transactions between or among the Company and its Subsidiaries,

         (c) transactions permitted by Section 4.07 hereof, and

         (d) loans and advances to employees and officers of the Company or any
     of its Subsidiaries in the ordinary course of business in an aggregate
     principal amount not to exceed $1.0 million at any one time outstanding,

     shall not be deemed Affiliate Transactions.

SECTION 4.12.  LIENS.

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

SECTION 4.13.  LIMITATIONS ON SALE AND LEASEBACK TRANSACTIONS.

                                       39
<PAGE>
 
         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, enter into, assume, Guarantee or otherwise become liable
with respect to any Sale and Leaseback Transaction, provided that the Company or
any Subsidiary of the Company may enter into any such transaction if (i) the
Company or such Subsidiary would be permitted under Sections 4.09 and 4.12
hereof to incur secured Indebtedness in an amount equal to the Attributable Debt
with respect to such transaction, (ii) the consideration received by the Company
or such Subsidiary from such transaction is at least equal to the Fair Market
Value of the property being transferred, and (iii) the Net Proceeds received by
the Company or such Subsidiary from such transaction are applied in accordance
with Section 4.10 hereof.

SECTION 4.14.  CORPORATE EXISTENCE.

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

SECTION 4.15.  OFFER TO PURCHASE UPON CHANGE OF CONTROL.

         (a) Upon the occurrence of a Change of Control, the Company shall make
an offer (the "Change of Control Offer") to each Holder of Debentures to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of
such Holder's Debentures at a purchase price equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest and Liquidated
Damages, if any, to the date of purchase (the "Change of Control Payment"),
provided that if the date of purchase is on or after an interest record date and
on or before the related interest payment date, any accrued interest shall be
paid to the Person in whose name a Debenture is registered at the close of
business on such record date, and no additional interest shall be paid or
payable to Holders who tender Debentures pursuant to the Change of Control
Offer. Within thirty (30) days following any Change of Control, the Company
shall mail a notice to the Trustee and each Holder stating: (1) that the Change
of Control Offer is being made pursuant to this Section 4.15 and that all
Debentures or portions thereof tendered will be accepted for payment; (2) the
purchase price and the purchase date, which shall be no earlier than 30 days nor
later than 40 days from the date such notice is mailed (the "Change of Control
Payment Date"); (3) that any Debenture or portion thereof not tendered will
continue to accrue interest in accordance with its terms; (4) that, unless the
Company defaults in the payment of the Change of Control Payment, all Debentures
or portions thereof accepted for payment pursuant to the Change of Control Offer
shall cease to accrue interest after the Change of Control Payment Date; (5)
that Holders electing to have any Debentures or portions thereof purchased
pursuant to a Change of Control Offer will be required to surrender the
Debentures, with the form entitled "Option of Holder to Elect Purchase" on the
reverse of the Debentures completed, to the Paying Agent at the address
specified in the notice prior to the close of business on the third Business Day
preceding the Change of Control Payment Date; (6) that Holders will be entitled
to withdraw their election if the Paying Agent receives, not later than the
close of business on the second Business Day preceding the Change of Control
Payment Date, a telegram, telex, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of Debentures or portions thereof
delivered for purchase, and a statement that such Holder is withdrawing his
election to have such Debentures or portions thereof purchased; and (7) that
Holders whose Debentures are being purchased only in part will be issued new
Debentures equal in principal amount to the unpurchased portion of the
Debentures surrendered, which 

                                       40
<PAGE>
 
unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof. The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the
repurchase of the Debentures or portions thereof in connection with a Change of
Control. Notwithstanding the foregoing, prior to complying with the provisions
of this Section 4.15, the Company shall either (i) repay all outstanding Senior
Debt or (ii) obtain the requisite consents, if any, under all agreements
governing outstanding Senior Debt to permit the repurchase of Debentures
hereunder.

         (b) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) accept for payment Debentures or portions thereof tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Debentures or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Debentures so accepted together with an Officers' Certificate
stating the Debentures or portions thereof tendered to the Company. The Paying
Agent shall promptly mail to each Holder of Debentures so accepted payment in an
amount equal to the purchase price for such Debentures or portions thereof, and
the Trustee shall promptly authenticate and mail to each Holder a new Debenture
equal in principal amount to any unpurchased portion of the Debentures
surrendered, if any; provided, that each such new Debenture shall be in a
principal amount of $1,000 or an integral multiple thereof. The Company shall
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

SECTION 4.16.  BUSINESS ACTIVITIES.

         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, engage in any business other than the Telecommunications
Business.

SECTION 4.17.  PAYMENTS FOR CONSENT.

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

SECTION 4.18.  NO SENIOR SUBORDINATED DEBT.

         The Company shall not incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Senior Debt and senior in any respect in right of
payment to the Debentures.

unless:

                                       41
<PAGE>
 
             (i) the Company is the surviving entity or the entity or Person
         formed by or surviving any such consolidation or merger (if other than
         the Company) or to which such sale, assignment, transfer, lease,
         conveyance or other disposition has been made is a corporation
         organized or existing under the laws of the United States, any state
         thereof or the District of Columbia;

         quarter (including any Indebtedness incurred or anticipated to be
         incurred in connection with or in respect of such transaction or series
         of transactions), either (A) could incur at least $1.00 of additional
         Indebtedness pursuant to the Consolidated Cash Flow Leverage Ratio test
         described under Section 4.09 hereof or (B) would have (x) Total Market
         Capitalization of at least $1.0 billion and (y) total Indebtedness in
         an amount no greater than 30% of its Total Market Capitalization; and

         license of the Company or its Subsidiaries that would have a material
         adverse effect on the business or operations of the Company and its
         Subsidiaries taken as a whole.

         Upon any consolidation or merger, or any sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,

substituted for (so that from and after the date of such consolidation, merger,
sale, lease, conveyance or other disposition, the provisions of this Indenture
referring to the Company shall refer instead to the successor corporation and
not to the Company), and may exercise every right and power of the Company under
this Indenture with the same effect as if such successor Person has been named
as the Company, herein; provided, however, that the predecessor Company shall
not be relieved from the obligations to pay the principal of, premium, if any,
and interest on the Debentures except in the case of a sale of all of the
Company's assets that meets the requirements of Section 5.01 hereof.

                             DEFAULTS AND REMEDIES

SECTION 6.01.  EVENTS OF DEFAULT.

         Each of the following constitutes an "Event of Default":

<PAGE>
 
         (1) the Company defaults in the payment of interest on, or Liquidated
     Damages, if any, with respect to the Debentures when the same becomes due
     and payable and the Default continues for a period of 30 days, whether or
     not such payment is prohibited by the provisions of Article 10 hereof;

         (2) the Company defaults in the payment of the principal of or premium,
     if any, on the Debentures when the same becomes due and payable at
     maturity, upon redemption or otherwise, whether or not such payment is

     pursuant to Sections 4.07, 4.09, 4.16 and 5.01 hereof;

         (4) the Company fails to comply with any of its other agreements or
     covenants in, or provisions of, this Indenture or the Exchange Indentures

     Debentures then outstanding;

         (5) a default occurs under any mortgage, indenture or instrument under
     which there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Subsidiaries
     (or the payment of which is guaranteed by the Company or any of its
     Subsidiaries), whether such Indebtedness or guarantee now exists, or is
     created after the Issue Date, which default (x) is caused by a failure to
     pay principal, premium, if any, or interest on such Indebtedness within the
     grace period provided in such Indebtedness (a "Payment Default"), and the
     principal amount of any such Indebtedness, together with the principal
     amount of any other such Indebtedness of the Company or any Significant
     Subsidiary under which there has been a Payment Default or the maturity of
     which has been accelerated as provided in clause (y), aggregates $5.0
     million or more or (y) results in the acceleration (which acceleration has
     not been rescinded) of such Indebtedness prior to its express maturity and
     the principal amount of any such Indebtedness, together with the principal
     amount of any other such Indebtedness under which there has been a Payment
     Default or the maturity of which has been so accelerated, aggregates $5.0
     million or more;

         (6) failure by the Company or any of its Significant Subsidiaries to

     within 45 days after their entry; and

         (7) the Company or any of its Significant Subsidiaries pursuant to or
     within the meaning of any Bankruptcy Law:

         substantially all of its property,

<PAGE>
 
             (a) is for relief against the Company or any Significant Subsidiary

             (c) orders the liquidation of the Company or any Significant

         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.

SECTION 6.02.  ACCELERATION.

         If any Event of Default occurs and is continuing under this Indenture,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Debentures may declare all of the Debentures to be due and payable
immediately, provided that the Existing Senior Notes outstanding, if any, have
become due and payable. Upon such declaration, the principal of premium, if any,
and accrued and unpaid interest and Liquidated Damages, if any, on the
Debentures shall be due and payable immediately. Notwithstanding the foregoing,
in the case of an Event of Default arising under Sections 6.01(g) and (h) hereof
with respect to the Company or any of its Significant Subsidiaries, the
foregoing amount shall ipso facto become due and payable without further action
or notice, provided that the Existing Senior Notes outstanding, if any, have
become due and payable. No premium is payable upon acceleration of the
Debentures except that in the case of an Event of Default that is the result of
an action or inaction by the Company or any of its Subsidiaries intended to
avoid restrictions on or premiums related to redemptions of the Debentures
contained in this Indenture or the Debentures, the amount declared due and
payable will include the premium that would have been applicable on a voluntary
prepayment of the Debentures or, if voluntary prepayment is not then permitted,
the premium set forth in this Indenture. Holders of the Debentures may not
enforce this Indenture or the Debentures except as provided in this Indenture.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Debentures pursuant to
Section 3.07, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law. If an Event of Default occurs prior to
March 31, 2001 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Company with the intention of avoiding the
prohibition on redemption of the Debentures prior to such date pursuant to
Section 3.07, then the premium payable for purposes of this paragraph for each
of the years beginning on March 31 of the years set forth below shall be as set
forth in the following table, expressed as a percentage of the amount that would
otherwise be due for the provisions of this paragraph, plus accrued interest, if
any, to the date of payment:

    YEAR                                                  PERCENTAGE
    1997.....................................................113.50%
    1998.....................................................112.15%
    1999.....................................................110.80%
    2000.....................................................109.45%
    2001 and thereafter .....................................108.10%

                                       44
<PAGE>
 
SECTION 6.03.  OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest on the Debentures or to enforce the performance of any provision of the
Debentures or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Debentures or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Debenture in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04.  WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in aggregate principal amount
of the Debentures then outstanding, by notice to the Trustee, may on behalf of
the Holders of all of the Debentures then outstanding, waive any existing
Default or Event of Default and its consequences under this Indenture, except a
continuing Default or Event of Default in the payment of interest or Liquidated
Damages or premium on, or the principal of, the Debentures then outstanding.
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.05.  CONTROL BY MAJORITY.

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

SECTION 6.06.  LIMITATION ON SUITS.

         No Holder of a Debenture shall have any right to institute any
proceeding with respect to this Indenture or the Debentures or for any remedy
thereunder, unless:

     requested, provide to the Trustee indemnity satisfactory to the Trustee
     against any loss, liability or expense; and

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

         Otherwise, no Holder of any Debenture shall have any right to institute
any proceeding with respect to this Indenture or the Debentures or for any
remedy thereunder, except:

                                       45
<PAGE>
 
         (x) a Holder of a Debenture may institute suit for enforcement of
payment of principal of and premium, if any, or interest on such Debenture on or
after the respective due dates expressed in such Debenture (including upon
acceleration thereof) or

or the Debentures or any remedy thereunder, including without limitation
acceleration, by the Holders of a majority in principal amount of the
outstanding Debentures; provided that, upon institution of any proceeding or
exercise of any remedy such Holders provide the Trustee with prompt written
notice thereof.

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

interest on the Debenture, on or after the respective due dates expressed in the
Debenture, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
the Holder of the Debenture.

SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium, if any, and interest remaining unpaid on the
Debentures and interest on overdue principal and, to the extent lawful, interest
and such further amount as shall be sufficient to cover the costs and expenses

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Debentures allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Debentures), the Company's creditors or
the Company's property and shall be entitled and empowered to collect, receive
and distribute any money or other property payable or deliverable on any such
claims and any custodian in any such judicial proceeding is hereby authorized by
each Holder of a Debenture to make such payments to the Trustee, and in the
event that the Trustee shall consent to the making of such payments directly to
the Holders of the Debentures, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties which the Holders of the
Debentures may be entitled to receive in such proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing
contained herein shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder of a Debenture any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder of a Debenture thereof, or to authorize the Trustee
to vote in respect of the claim of any Holder of a Debenture in any such
proceeding.

to Holders of Debentures.

SECTION 6.11.  UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by

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.

a Debenture pursuant to Section 6.07 hereof, or a suit by Holders of more than

                                    TRUSTEE

SECTIDUTIES OF TRUSTEE.

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

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

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

         (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine 

                                       47
<PAGE>
 
     the certificates and opinions to determine whether or not they conform to
     the requirements of this Indenture.

negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

     Section 7.01;

     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05 hereof.

Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with

and complete authorization and protection from liability in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance

rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have provided to the

Trustee reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or
direction.

SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the

Trustee. However, in the event that the Trustee acquires any conflicting
interest, it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with like
rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

money paid to the Company or upon the Company's direction under any provision of
this Indenture, it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the
Debentures or any other document in connection with the sale of the Debentures
or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05.  NOTICE OF DEFAULTS.

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

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

         Within 60 days after each May 15th beginning with the May 15th
following the date of this Indenture, the Trustee shall mail to the Holders of
the Debentures a brief report dated as of such reporting date that complies with
TIA ss. 313(a) (but if no event described in TIA ss. 313(a) has occurred within
the twelve months preceding the reporting date, no report need be transmitted).
The Trustee also shall comply with TIA ss. 313(b)(2). The Trustee shall also
transmit by mail all reports as required by TIA ss. 313(c).

         A copy of each report at the time of its mailing to the Holders of
Debentures shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Debentures are listed. The Company shall promptly notify
the Trustee when the Debentures are listed on any stock exchange.

SECTION 7.07.  COMPENSATION AND INDEMNITY.

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

                                       49
<PAGE>
 
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, except any such
loss, liability or expense as may be attributable to the negligence or bad faith
of the Trustee. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim and the Trustee shall cooperate in the defense. The Trustee, in
its sole discretion, may elect to have separate counsel selected by it and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall

the satisfaction and discharge of this Indenture.

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

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

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

may remove the Trustee if:

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

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

of a majority in principal amount of the then outstanding Debentures may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.

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

         If the Trustee after written request by any Holder of a Debenture who
has been a Holder of a Debenture for at least six months fails to comply with
Section 7.10 hereof, such Holder of a Debenture 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 Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Debentures. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

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

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any state thereof authorized under such laws to exercise corporate
trustee power, shall be subject to supervision or examination by federal or
state authority and shall have a combined capital and surplus of at least $25.0
million as set forth in its most recent published annual report of condition.

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

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate and at any time, with respect
to the Debentures, elect to have either Section 8.02 or 8.03 

                                       51
<PAGE>
 
hereof be applied to all outstanding Debentures upon compliance with the
conditions set forth below in this Article 8.

SECTION 8.02.  LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall be deemed to have been
discharged from its obligations with respect to all outstanding Debentures on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire Indebtedness represented
by the outstanding Debentures, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all of its other obligations under such Debentures and this Indenture
(and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of outstanding Debentures to receive from the trust described below
payments in respect of the principal of, premium, if any, and interest on and
Liquidated Damages with respect to, such Debentures when such payments are due,
or on the redemption date, as the case may be; (b) the Company's obligations
with respect to the Debentures concerning issuing temporary Debentures,
registration of Debentures, mutilated, destroyed, lost or stolen Debentures and

SECTION 8.03.  COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall be released from its
obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof and Article 5
hereof with respect to the outstanding Debentures on and after the date the
conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"),
and the Debentures shall thereafter be deemed not "outstanding" for the purposes
of any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Debentures shall not be deemed outstanding for accounting
purposes). For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Debentures, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Sections 6.01 (c), (d), (e) or (f) hereof but, except as specified above, the
remainder of this Indenture and such Debentures shall be unaffected thereby. In
addition, upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, Sections 6.01(g) through 6.01(h) hereof shall
not constitute Events of Default.

SECTION 8.04.  CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

8.02 or Section 8.03 hereof to the outstanding Debentures:

     dedicated solely to, the benefit of the Holders of such Debentures, (i)

     of a nationally recognized firm of independent public accountants selected
     by the Company, to pay the principal of, premium, if any, and interest on,
     and Liquidated Damages with respect to outstanding Debentures, the stated
     maturity or on the applicable optional redemption date, as the case may be,
     of such principal or installment of principal of, premium, if any, or
     interest on the outstanding Debentures;

         (b) In the case of legal defeasance, the Company shall deliver to the
     Trustee an opinion of counsel in the United States reasonably acceptable to
     the Trustee confirming that (i) the Company has received from, or there has
     been published by, the Internal Revenue Service a ruling or (ii) since the
     Issue Date, there has been a change in the applicable federal income tax
     law, in either case to the effect that, and based thereon such opinion of
     counsel shall confirm that, the Holders of the outstanding Debentures will
     not recognize income, gain or loss for federal income tax purposes as a
     result of such legal defeasance and will be subject to federal income tax
     on the same amounts, in the same manner and at the same times as would have
     been the case if such legal defeasance had not occurred;

         (c) In the case of covenant defeasance, the Company shall deliver to
     the Trustee an opinion of counsel in the United States reasonably
     acceptable to the Trustee confirming that the Holders of the outstanding
     Debentures will not recognize income, gain or loss for federal income tax
     purposes as a result of such covenant defeasance and will be subject to
     federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if such covenant defeasance had not
     occurred;

         (d) No Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the 91st day
     after the date of deposit;

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

         (f) The Company shall have delivered to the Trustee an opinion of
     counsel to the effect that after the 91st day (or such other applicable
     date) following the deposit, the trust funds will not be subject to the
     effect of any applicable bankruptcy, insolvency, reorganization or similar
     laws affecting creditors' rights generally;

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

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

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

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

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or Government Securities
deposited pursuant to Section 8.04 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the outstanding Debentures.

         Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or Government Securities held by it as provided in Section
8.04 hereof which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are
in excess of the amount thereof which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06.  REPAYMENT TO COMPANY.

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

SECTION 8.07.  REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
Dollars or Government Securities in accordance with Section 8.02 or 8.03 hereof,
as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Debentures shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or
8.03 hereof, as the case may be; provided, however, that, if the Company makes
any payment of principal of, premium, if any, or interest on any Debenture
following the reinstatement of its obligations, the Company shall be subrogated
to the rights 

                                       54
<PAGE>
 
of the Holders of such Debentures to receive such payment from the money held by
the Trustee or Paying Agent.

                                   ARTICLE 9

                       AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.  WITHOUT CONSENT OF HOLDERS OF DEBENTURES.

         Notwithstanding Section 9.02 hereof, the Company and the Trustee may
amend or supplement this Indenture or the Debentures without the consent of any
Holder of a Debenture:

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

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

         (c) to provide for the assumption of the Company's obligations to
             Holders of the Debentures in the case of a merger or consolidation;

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

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

         Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such amended
or supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 9.06 hereof, the Trustee shall join with the Company in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations which may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture which affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02.  WITH CONSENT OF HOLDERS OF DEBENTURES.

         The Company and the Trustee may amend or supplement this Indenture or
the Debentures or any amended or supplemental Indenture with the written consent
of the Holders of Debentures of at least a majority in aggregate principal
amount of the Debentures then outstanding (including consents obtained in
connection with a tender offer or exchange offer for the Debentures), and any
existing Default and its consequences or compliance with any provision of this
Indenture or the Debentures may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Debentures (including
consents obtained in connection with a tender offer or exchange offer for the
Debentures).

         Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such amended
or supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Debentures as
aforesaid, and upon receipt by the Trustee of the documents described in Section
9.06 hereof, the Trustee shall join with the Company in the execution of such
amended or supplemental Indenture unless such amended or supplemental Indenture
affects the Trustee's own rights, duties or immunities under this Indenture or

                                       55
<PAGE>
 
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental Indenture.

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

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

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

         (ii)reduce the principal of or change the fixed maturity of any
             Debenture or alter the provisions with respect to the redemption of
             the Debentures (other than Sections 3.09 and 4.15 hereof);

        (iii)reduce the rate of or change the time for payment of interest on
             any Debentures;

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

         (v) make any Debenture payable in money other than that stated in the
             Debentures;

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

        (vii) waive a redemption payment with respect to any Debenture (other
              than a payment required by Sections 3.09 or 4.15 hereof); or

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

     In addition, any amendment to the provisions of Article 10 hereof shall
required the consent of the Holders of at least 75% in aggregate principal
amount of the Debentures then outstanding if such amendment would adversely
affect the rights of Holders of Debentures.

SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

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

                                       56
<PAGE>
 
SECTION 9.04.  REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Debenture is a continuing consent by the Holder of a
Debenture and every subsequent Holder of a Debenture or portion of a Debenture
that evidences the same debt as the consenting Holder's Debenture, even if
notation of the consent is not made on any Debenture. However, any such Holder
of a Debenture or subsequent Holder of a Debenture may revoke the consent as to
its Debenture if the Trustee receives written notice of revocation before the
date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder of a Debenture.

         The Company may fix a record date for determining which Holders of the
Debentures must consent to such amendment, supplement or waiver. If the Company
fixes a record date, the record date shall be fixed at (i) the later of 30 days
prior to the first solicitation of such consent or the date of the most recent
list of Holders of Debentures furnished to the Trustee prior to such
solicitation pursuant to Section 2.05 hereof or (ii) such other date as the
Company shall designate.

SECTION 9.05.  NOTATION ON OR EXCHANGE OF DEBENTURES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Debenture thereafter authenticated. The Company in
exchange for all Debentures may issue and the Trustee shall authenticate new
Debentures that reflect the amendment, supplement or waiver.

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

SECTION 9.06.  TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental Indenture until the Board of Directors
approves it.

SECTION 9.07.  PAYMENT FOR CONSENTS.

         The Company shall not, and shall 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 of Debentures for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture, the Registration Rights Agreement or the Debentures, unless
such consideration is offered to be paid or agreed to be paid to all Holders of
the Debentures that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement.

                                   ARTICLE 10

                                  SUBORDINATION

SECTION 10.01.  AGREEMENT TO SUBORDINATE.

         The Company agrees, and each Holder by accepting a Debenture agrees,
that the Indebtedness evidenced by the Debentures is subordinated in right of
payment, to the extent and in the manner provided in this Article 10, to the
prior payment in full of all Senior Debt (whether outstanding on the date hereof
or hereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the Holders of Senior Debt.

SECTION 10.02.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.

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

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

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

SECTION 10.03.  DEFAULT ON DESIGNATED SENIOR DEBT.

         The Company may not make any payment or distribution to the Trustee or
any Holder in respect of Obligations with respect to the Debentures and may not
acquire from the Trustee or any Holder any Debentures for cash or property
(other than (i) Permitted Junior Securities and (ii) payments and other
distributions made from any defeasance trust created pursuant to Section 8.01
hereof), if:

         (i) a default in the payment of any principal or other Obligations with
     respect to Designated Senior Debt occurs and is continuing beyond any
     applicable grace period in the agreement, indenture or other document
     governing such Designated Senior Debt; or

         (ii)a default, other than a payment default, on Designated Senior Debt
     occurs and is continuing that then permits Holders of the Designated Senior
     Debt to accelerate its maturity and the Trustee receives a notice of the
     default (a "Payment Blockage Notice") from a Person who may give it
     pursuant to Section 10.11 hereof. If the Trustee receives any such Payment
     Blockage Notice, no subsequent Payment Blockage Notice shall be effective
     for purposes of this Section unless and until (1) at least 360 days shall
     have elapsed since the effectiveness of the immediately prior Payment
     Blockage Notice and (ii) all scheduled payments of principal, premium, if
     any, and interest on the Debentures that have come due have been paid in
     full in cash. No nonpayment default that existed or was continuing on the
     date of 

                                       58
<PAGE>
 
     delivery of any Payment Blockage Notice to the Trustee shall be, or be
     made, the basis for a subsequent Payment Blockage Notice. No more than one
     Payment Blockage Notice to the Trustee may be given in any 360 day period.

         The Company may and shall resume payments on and distributions in
respect of the Debentures and may acquire them upon the earlier of:

         (1) the date upon which the default is cured or waived, or

         (2) in the case of a default referred to in Section 10.03(ii) hereof,
     179 days pass after notice is received if the maturity of such Designated
     Senior Debt has not been accelerated,

if this Article 10 otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

SECTION 10.04.  ACCELERATION OF DEBENTURES.

         If payment of the Debentures is accelerated because of an Event of
Default, the Company shall promptly notify Holders of Senior Debt of the
acceleration.

SECTION 10.05.  WHEN DISTRIBUTION MUST BE PAID OVER.

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

         With respect to the Holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the Holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
Holders of Senior Debt, and shall not be liable to any such Holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any Holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

SECTION 10.06.  NOTICE BY COMPANY.

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

SECTION 10.07.  SUBROGATION.

                                       59
<PAGE>
 
         After all Senior Debt is paid in full and until the Debentures are paid
in full, Holders of Debentures shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Debentures) to the rights of Holders of
Senior Debt to receive distributions applicable to Senior Debt to the extent
that distributions otherwise payable to the Holders of Debentures have been
applied to the payment of Senior Debt. A distribution made under this Article 10
to Holders of Senior Debt that otherwise would have been made to Holders of
Debentures is not, as between the Company and Holders, a payment by the Company
on the Debentures.

SECTION 10.08.  RELATIVE RIGHTS.

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

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

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

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

         If the Company fails because of this Article 10 to pay principal of or
interest on a Debenture on the due date, the failure is still a Default or Event
of Default.

SECTION 10.09.  SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

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

SECTION 10.10.  DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

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

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

SECTION 10.11.  RIGHTS OF TRUSTEE AND PAYING AGENT.

                                       60
<PAGE>
 
         Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Debentures, unless the Trustee shall have received at
its Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Debentures to violate this Article 10. Only the Company or a
Representative may give the notice. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

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

SECTION 10.12.  AUTHORIZATION TO EFFECT SUBORDINATION.

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

SECTION 10.13.  AMENDMENTS.

         The provisions of this Article 10 shall not be amended or modified
without the written consent of the Holders of all Senior Debt.

                                  ARTICLE 11

                                 MISCELLANEOUS

SECTION 11.01.  TRUST INDENTURE ACT CONTROLS.

         If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by TIA ss. 318(c), the imposed duties shall control.

SECTION 11.02.  NOTICES.

         Any notice or communication by the Company or the Trustee to the other
is duly given if in writing and delivered in Person or mailed by first class
mail (registered or certified, return receipt requested), telex, telecopier or

         The Company or the Trustee, by notice to the other may designate

Any notice or communication shall also be so mailed to any Person described in
TIA ss. 313(c), to the extent required by the TIA. Failure to mail a notice or

its sufficiency with respect to other Holders of Debentures.

         If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee

         If the Company mails a notice or communication to Holders of
Debentures, it shall mail a copy to the Trustee and each Agent at the same time.

                DEBENTURES.

         Holders of the Debentures may communicate pursuant to TIA ss. 312(b)

SECTION 11.05.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

         Each certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture (other than a certificate provided
pursuant to TIA ss. 314(a)(4)) shall include:

         (a) a statement that the Person making such certificate or opinion has
     read such covenant or condition;

         (b) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such

SECTION 11.06.  RULES BY TRUSTEE AND AGENTS.

         The Trustee may make reasonable rules for action by or at a meeting of

Company, as such, shall have any liability for any obligations of the Company
under the Debentures or this Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder of the
Debentures by accepting a Debenture waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Debentures.
Such waiver may not be effective to waive liabilities under the federal

public policy.

         All agreements of the Company in this Indenture and the Debentures
shall bind its successors. All agreements of the Trustee in this Indenture shall
bind its successor.

SECTION 11.11.  SEVERABILITY.

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

SECTION 11.12.  COUNTERPART ORIGINALS.

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

articles and sections of this Indenture have been inserted for convenience of

                              (Back of Debenture)

                13 1/2% Senior Subordinated Debentures due 2009

         Capitalized terms used herein have the meanings assigned to them in the
Indenture (as defined below) unless otherwise indicated.

         1. Interest. Intermedia Communications Inc., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this
Debenture at the rate and in the manner specified below. Interest will accrue at
the rate of 13 1/2% per annum and will be payable semi-annually, in arrears, on
March 31 and September 30 of each year, commencing on the first such date after
the issuance date of the Debentures, or if any such day is not a Business Day on
the next succeeding Business Day (each an "Interest Payment Date") to Holders of
record of the Debentures at the close of business on the immediately preceding
March 15 and September 15, whether or not a Business Day. Interest on the
Debentures will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the Issue Date. Interest payable on or
prior to March 31, 2002 may be paid in the form of additional Debentures valued
at the principal amount thereof. Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months. To the extent lawful, the
Company shall pay interest on overdue principal at the then applicable interest
rate on the Debentures; it shall pay interest on overdue installments of
interest (without regard to any applicable grace periods) at the same rate to
the extent lawful.

         2. Method of Payment. The Company will pay interest on the Debentures
(except defaulted interest) to the Persons who are registered Holders of
Debentures at the close of business on the record date next preceding the
Interest Payment Date, even if such Debentures are cancelled after such record
date and on or before such Interest Payment Date. The Holder hereof must
surrender this Debenture to a Paying Agent to collect principal payments.
Principal, premium, if any, and interest and Liquidated Damages on the
Debentures will be payable at the office or agency of the Company maintained for
such purpose within the City and State of New York or, at the option of the
Company, payment of interest and Liquidated Damages may be made by check mailed
to the Holders of the Debentures at their respective addresses set forth in the
register of Holders of Debentures; provided that all payments with respect to
Global Debentures and Certificated Securities the Holders of which have given
wire transfer instructions to the Company will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof. Unless otherwise designated by the Company, the Company's office or
agency in New York will be the office of the Trustee maintained for such
purpose.

         3. Paying Agent and Registrar. Initially, the Trustee will act as
Paying Agent and Registrar. The Company may change any Paying Agent, Registrar
or co-registrar without prior notice to any Holder of a Debenture. The Company
may act in any such capacity.

         4. Indenture. The Company issued the Debentures under an Indenture,
dated as of ________ (the "Indenture"), between the Company and the Trustee. The
terms of the Debentures include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb), as in effect on the date of the
Indenture. The Debentures are subject to all such terms, and Holders of
Debentures are referred to the Indenture and such act for a statement of such
terms. The terms of the Indenture shall govern any inconsistencies between the
Indenture and the Debentures. The Debentures are obligations of the Company
limited to the sum of $____________ million in aggregate principal amount of
Debentures to be issued on the Issue Date.

         5. Optional Redemption. Except as set forth below, the Debentures will
not be redeemable at the Company's option prior to March 31, 2002. Thereafter,
the Debentures will be subject to redemption at the option of the Company, in
whole or in part, upon not less than 30 nor more than 60 days' notice to the
Holders 

                                      A-3
<PAGE>
 
thereof, at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the applicable redemption date, if redeemed during the twelve-month
period beginning on March 31 of the years indicated below:

    YEAR                                              PERCENTAGE
    2002.................................................106.75%
    2003................................................ 105.40%
    2004 ................................................104.05%
    2005................................................ 102.70%
    2006 ................................................101.35%
    2007 and thereafter..................................100.00%

        (b) Notwithstanding the provisions above, prior to March 31, 2000, the
Company may, on any one or more occasions, use the net proceeds of one or more
underwritten public offerings of its Common Stock or from the sale of its
Capital Stock (other than Disqualified Stock) to a Strategic Investor in a
single transaction or series of related transactions for an aggregate purchase
price equal to or exceeding $50.0 million, to redeem up to a maximum of 35% of
the aggregate principal amount of the Debentures originally issued from the net
cash proceeds of such sale or offering (but only to the extent such proceeds
consist of cash or readily marketable cash equivalents) at a redemption price
equal to 113 1/2% of the principal amount thereof with respect to the Debentures
to be redeemed on the redemption date, provided that at least 65% of the
aggregate principal amount of the Debentures originally issued remains
outstanding immediately after the occurrence of such redemption and that such
redemption occurs within 90 days of the date of the closing of such sale.

         6. Mandatory Redemption. Except as set forth in Sections 3.09 and 4.15
of the Indenture, the Company will not be required to make mandatory redemption
or sinking fund payments with respect to the Debentures.

         7. Repurchase at Option of Holder. (a) Upon the occurrence of a Change
of Control, the Company shall be required to offer to purchase on the Change of
Control Payment Date all outstanding Debentures at a purchase price equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, to the Change of Control Payment Date. Holders
of Debentures that are subject to an offer to purchase will receive a Change of
Control Offer from the Company prior to any related Change of Control Payment
Date and may elect to have such Debentures purchased by completing the form
entitled "Option of Holder to Elect Purchase" appearing below.

         (b) The Company shall be required when the cumulative amount of Excess
Proceeds from Asset Sales exceeds $5.0 million to offer to purchase the maximum
principal amount of Debentures and Pari Passu Notes that may be purchased out of
the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
outstanding principal amount of the Debentures and the Pari Passu Notes, plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
fixed for the closing of such offer. If the aggregate principal amount of
Debentures and Pari Passu Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Debentures and Pari Passu Notes to be purchased
shall be selected on a pro rata basis based upon their principal amount (with
such adjustments as may be deemed appropriate by the Company so that only
Debentures and Pari Passu Notes in denominations of $1,000, or integral
multiples thereof shall be purchased). Holders of Debentures that are the
subject of an offer to purchase will receive an Excess Proceeds Offer from the
Company prior to any related purchase date and may elect to have such Debentures
purchased by completing the form entitled "Option of Holder to Elect Purchase"
appearing below.

         8. Notice of Redemption. Notice of redemption shall be mailed by first
class mail at least 30 days but not more than 60 days before the redemption date
to each Holder whose Debentures are to be redeemed 

                                      A-4
<PAGE>
 
at its registered address. Debentures may be redeemed in part but only in whole
multiples of $1,000, unless all of the Debentures held by a Holder of Debentures
are to be redeemed. If any Debenture is to be redeemed in part only, the notice
of redemption that relates to such Debenture shall state the portion of the
principal amount to be redeemed. On and after the redemption date, interest
ceases to accrue on Debentures or portions of them called for redemption.

         9. Denominations, Transfer, Exchange. The Debentures are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Debentures may be registered and Debentures may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder of a Debenture, among other things, to furnish appropriate
endorsements and transfer documents and the Company may require a Holder of a
Debenture to pay any taxes and fees required by law or permitted by the
Indenture. Neither the Company nor the Registrar need exchange or register the
transfer of any Debenture or portion of a Debenture selected for redemption.
Also, neither the Company nor the Registrar need exchange or register the
transfer of any Debentures for a period of 15 days before a selection of
Debentures to be redeemed.

         10. Persons Deemed Owners. Prior to due presentment to the Trustee for
registration of the transfer of this Debenture, the Trustee, any Agent and the
Company shall deem and treat the Person in whose name this Debenture is
registered as its absolute owner for the purpose of receiving payment of
principal of, premium, if any, and interest and Liquidated Damages, if any, on
this Debenture and for all other purposes whatsoever, whether or not this
Debenture is overdue, and neither the Trustee, any Agent nor the Company shall
be affected by notice to the contrary. The registered Holder of a Debenture
shall be treated as its owner for all purposes.

         11. Amendments, Supplement and Waivers. Subject to certain exceptions,
the Indenture or the Debentures may be amended or supplemented with the consent
of the Holders of at least a majority in principal amount of the then
outstanding Debentures (including consents obtained in connection with a tender
offer or exchange offer for Debentures), and any existing default or compliance
with any provision of the Indenture or the Debentures may be waived with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Debentures (including consents obtained in connection with a tender
offer or exchange offer for Debentures). Without the consent of any Holder of a
Debenture, the Indenture or the Debentures may be amended or supplemented to
cure any ambiguity, defect or inconsistency; to provide for uncertificated
Debentures in addition to or in place of certificated Debentures; to provide for
the assumption of the Company's obligations to Holders of the Debentures in case
of a merger or consolidation; to make any change that would provide any
additional rights or benefits to the Holders of the Debentures or that does not
adversely affect the legal rights under the Indenture of any such Holder; or to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act. However, without
the consent of each Holder affected, an amendment or waiver may not (with
respect to any Debentures held by a nonconsenting Holder of Debentures) reduce
the principal amount of Debentures whose Holders must consent to an amendment,
supplement or waiver; reduce the principal of or change the fixed maturity of
any Debenture or alter the provisions with respect to the redemption of the
Debentures (other than a payment required by Section 3.09 or Section 4.15 of the
Indenture); reduce the rate of or change the time for payment of interest on any
Debenture; waive a Default or Event of Default in the payment of principal of or
premium, if any, or interest on the Debentures (except a rescission of
acceleration of the Debentures by the Holders of at least a majority in
aggregate principal amount of the then outstanding Debentures and a waiver of
the payment default that resulted from such acceleration); make any Debenture
payable in money other than that stated in the Debentures; make any change in
the provisions of the Indenture relating to waivers of past Defaults or the
rights of Holders of Debentures to receive payments of principal of, premium, if
any, or interest on any Debenture; waive a redemption payment with respect to
any Debenture (other than a payment required by Section 3.09 or Section 4.15 of
the Indenture) or make any change in the foregoing amendment and waiver
provisions.

         12. Defaults and Remedies. Events of Default include: (i) a default in
the payment of interest on, or Liquidated Damages, if any, with respect to the
Debentures when the same becomes due and payable and the Default continues for a
period of 30 days, whether or not such payment is prohibited by the provisions
of Article 10 of the Indenture; (ii) a default in the payment of the principal
of or premium, if any, on the Debentures when the same becomes due and payable
at maturity, upon redemption or otherwise, whether or not such payment is
prohibited by the provisions of Article 10 of the Indenture; (iii) failure to
perform or comply with any covenant, condition or agreement on the part of the
Company to be observed or performed pursuant to Sections 4.07, 4.09, 4.16 and
5.01 of the Indenture; (iv) failure to comply with any of its other agreements
or covenants in, or provisions of, this Indenture or the Exchange Indentures and
the Default continues for the 30 days after given notice thereof by the Trustee
or the Holders of at least 25% in principal amount of the Debentures then
outstanding; (v) a default occurs under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Subsidiaries
(or the payment of which is guaranteed by the Company or any of its
Subsidiaries), whether such Indebtedness or guarantee now exists, or is created
after the Issue Date, which default (x) is caused by a failure to pay principal,
premium, if any, or interest on such Indebtedness within the grace period
provided in such Indebtedness (a "Payment Default"), and the principal amount of
any such Indebtedness, together with the principal amount of any other such
Indebtedness of the Company or any Significant Subsidiary under which there has
been a Payment Default or the maturity of which has been accelerated as provided
in clause (y), aggregates $5.0 million or more or (y) results in the
acceleration (which acceleration has not been rescinded) of such Indebtedness
prior to its express maturity and the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $5.0 million or more; (vi) failure by the Company or any
of its Significant Subsidiaries to pay final judgments (other than any judgment
as to which a reputable insurance company has accepted full liability in
writing) aggregating in excess of $5.0 million which judgments are not paid,
discharged or stayed within 45 days after their entry; and (vii) certain events
of bankruptcy or insolvency with respect to the Company or any of its
Significant Subsidiaries. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Debentures may declare all the Debentures to be due and payable
immediately, provided that the Existing Senior Notes outstanding, if any, have
become due and payable. Upon such declaration, the principal of premium, if any,
and accrued and unpaid interest and Liquidated Damages, if any, on the
Debentures shall be due and payable immediately. Notwithstanding the foregoing,
in the case of an Event of Default arising from certain events of bankruptcy or
insolvency with respect to the Company or any of its Subsidiaries, the foregoing
amount shall ipso facto become due and payable without further action or notice,
provided that the Existing Senior Notes outstanding, if any, have become due and
payable. Holders of the Debentures may not enforce the Indenture or the
Debentures except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Debentures may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Debentures notice of any continuing Default or
Event of Default (except a Default or Event of Default relating to the payment
of principal or interest on the Debentures) if it determines that withholding
notice is in such Holders' interest. The Holders of a majority in aggregate
principal amount of the Debentures then outstanding, by notice to the Trustee,
may on behalf of the Holders of all of the Debentures, waive any existing
Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest or premium on,
or the principal of, the Debentures. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default to
deliver to the Trustee a statement specifying such Default or Event of Default.

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

                                      A-6
<PAGE>
 
acquires any conflicting interest it must eliminate such conflict within
90 days, apply to the SEC for permission to continue as Trustee or resign.

         14. Subordination. Each Holder by accepting a Debenture agrees that the
payment of principal of, premium and Liquidated Damages, if any, and interest on
each Debenture is subordinated in right of payment, to the extent and in the
manner provided in the Indenture, to the prior payment in full of all Senior
Debt in cash or Cash Equivalents (whether outstanding on the date of the
Indenture or thereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the Holders of Senior Debt.

         15. No Personal Liabilities of Directors, Officers, Employees and
Stockholders. No director, officer, employee, incorporator or stockholder of the
Company, as such, shall have any liability for any obligations of the Company
under the Debentures or the Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder of the
Debentures by accepting a Debenture waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Debentures.

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

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

         18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Debentures and has directed the Trustee to
use CUSIP numbers in notices of redemption as a convenience to Holders of
Debentures. No representation is made as to the accuracy of such numbers either
as printed on the Debentures or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

         19. Additional Rights of Holders of Transfer Restricted Securities. In
addition to the rights provided to Holders of Debentures under the Indenture,
Holders of Transfer Restricted Securities shall have all the rights set forth in
the Registration Rights Agreement described in the Indenture.

           FORM OF LETTER TO BE DELIVERED BY ACCREDITED INSTITUTIONS

         We are delivering this letter in connection with an offering of 13 1/2%
Senior Subordinated Debentures due 2009 (the "Debentures") of Intermedia
Communications Inc., a Delaware corporation (the "Company"), all as described in
the Offering Memorandum (the "Offering Memorandum") relating to the offering.

         We hereby confirm that:

             (i) we are an "accredited investor" within the meaning of Rule
         501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
         (the "Securities Act"), or an entity in which all of the equity owners
         are accredited investors within the meaning of Rule 501(a)(1), (2), (3)
         or (7) under the Securities Act (an "Institutional Accredited
         Investor");

             (ii) any purchase of Debentures by us will be for our own account
         or for the account of one or more other Institutional Accredited
         Investors;

             (iii) in the event that we purchase any Debentures, we will acquire
         Debentures having a minimum purchase price of at least $100,000 for our
         own account and for each separate account for which we are acting;

             (iv) we have such knowledge and experience in financial and
         business matters that we are capable of evaluating the merits and risks
         of purchasing Debentures;

             (v) we are not acquiring Debentures with a view to any distribution
         thereof in a transaction that would violate the Securities Act or the
         securities laws of any State of the United States or any other
         applicable jurisdiction; provided that the disposition of our property
         and the property of any accounts for which we are acting as fiduciary
         shall remain at all times within our control; and

             (vi) we have received a copy of the Offering Memorandum and
         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 Company and receive answers
         thereto, as we deem necessary in connection with our decision to
         purchase Debentures.

         We understand that the Debentures are being offered in a transaction
not involving any public offering within the meaning of the Securities Act and
that the Debentures have not been registered under the Securities Act, and we
agree, on our own behalf and on behalf of each account for which we acquire any
Debentures, that such Debentures may be offered, resold, pledged or otherwise
transferred only (i) to a person whom we reasonably believe to be a qualified
institutional buyer (as defined in Rule 144A, under the Securities Act) in a
transaction meeting the requirements of Rule 144A, in a transaction meeting the
requirements of Rule 144 under the Securities Act, outside the United States in
a transaction meeting the requirements of Rule 904 under the Securities Act, or
in accordance with another exemption from the registration requirements of the
Securities Act (and based upon an opinion of counsel if the Company so
requests), (ii) to the Company or (iii) 

                                      C-1
<PAGE>
 
pursuant to an effective registration statement, and, in each case, in
accordance with any applicable securities laws of any State of the United States
or any other applicable jurisdiction. We understand that the registrar and
transfer agent will not be required to accept for registration of transfer any
Debentures, except upon presentation of evidence satisfactory to the Company
that the foregoing restrictions on transfer have been complied with.

         We acknowledge that you, the Company and others will rely upon our
confirmations, acknowledgements and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.

         THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE

                         AMENDMENT TO RIGHTS AGREEMENT

               Agreement (this "Amendment") dated as of February 20, 1997,
between Intermedia Communications Inc., a Delaware Corporation (the "Company")
f/k/a Intermedia Communications of Florida, Inc., and Continental Stock Transfer
& Trust Company (the "Rights Agent").

               Reference is made to the Rights Agreement between the Company and
the Rights Agent, dated as of March 7, 1996 (the "Agreement"). Capitalized terms
used herein and not otherwise defined herein have the respective meanings
ascribed to them in the Agreement.

        1.     Paragraph (b) of Section 7 of the Agreement is hereby
deleted and replaced with the following:

               (b) The purchase price for each one-thousandth of a share (each
        such one one-thousandth of a share being a "Unit") of Preferred Stock
        upon exercise of Rights shall be $85.00, subject to adjustment from time
        to time as provided in Sections 11 and 13(a) hereof (such purchase
        price, as so adjusted, being the "Purchase Price"), and shall be payable
        in accordance with paragraph (c) below.

        2.     The second sentence of paragraph (d)(ii) of Section 11
of the Agreement is hereby deleted and replaced with the following:

        If the current market price per share of Preferred Stock cannot be
        determined in the manner provided above or if the Preferred Stock is not
        publicly held or listed or traded in a manner described in clause (i) of
        this section 11(d), the "current market price" per share of Preferred
        Stock shall be conclusively deemed to be an amount equal to 1000 (as
        such amount may be appropriately adjusted for such events as stock
        splits, stock dividends and recapitalizations with respect to Company
        Common Stock occurring after the date of this Agreement) multiplied by
        the current market price per share of Company Common Stock.

        3.     The last sentence of paragraph (d)(ii) of Section 11 of
the Agreement is hereby deleted and replaced with the following:

        For all purposes of this Agreement, the "current market price" of a Unit
        of Preferred Stock shall be equal to the "current market price" of one
        share of Preferred Stock divided by 100 .
<PAGE>
 
        4.     Paragraph (b) of Section 14 of the Agreement is hereby
deleted and replaced with the following:

               (b) The Company shall not be required to issue fractions of
        shares of Preferred Stock (other than fractions which are integral
        multiples of one one-thousandth of a share of Preferred Stock) upon
        exercise of the Rights or to distribute certificates which evidence such
        fractional shares of Preferred Stock (other than fractions which are
        integral multiples of one one-thousandth of a share of Preferred Stock).
        In lieu of such fractional shares of Preferred Stock that are not
        integral multiples of one one-thousandth of a share, the Company may pay
        to the registered holders of Rights Certificates at the time such Rights
        are exercised as herein provided an amount in cash equal to the same
        fraction of the then current market price of a share of Preferred Stock
        on the day of exercise, determined in accordance with Section 11(d)
        hereof.

        5. The term Unit as used throughout the Agreement, including any
exhibits to the Agreement and any certificates issued pursuant thereto, shall
have the meaning set forth above in Paragraph 1 of this Amendment.

        6.     Exhibit C is hereby amended to reflect that the number
of authorized Series A Preferred Shares shall be 40,000.


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

SECTION 2.            HOLDERS

               A Person is deemed to be a holder of Transfer Restricted
Securities (each, a "Holder") whenever such Person owns Transfer Restricted
Securities.


SECTION 3.            REGISTERED EXCHANGE OFFER

               (a) Unless the Exchange Offer shall not be permitted by
applicable federal law (after the procedures set forth in Section 6(a)(i) below
have been complied with), the Company shall (i) cause to be filed with the
Commission as soon as practicable after the Closing Date, but in no event later
than 30 days after the Closing Date, the Exchange Offer Registration Statement,
(ii) use its best efforts to cause such Exchange Offer Registration Statement to
become effective at the earliest possible time, but in no event later than 120
days after the Closing Date, (iii) in connection with the foregoing, (A) file
all pre-effective amendments to such Exchange Offer Registration Statement as
may be necessary in order to cause such Exchange Offer Registration Statement to
become effective, (B) file, if applicable, a post-effective amendment to such
Exchange Offer Registration Statement pursuant to Rule 430A under the Act and
(C) cause all necessary filings, if any, in connection with the registration and
qualification of the New Preferred Stock or the New Exchange Debentures, as the
case may be, to be made under the Blue Sky laws of such jurisdictions as are
necessary to permit Consummation of the Exchange Offer and (iv) upon the
effectiveness of such Exchange Offer Registration Statement, commence and
Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate
form permitting registration of the New Preferred Stock or the New Exchange
Debentures, as the case may be, to be offered in exchange for the Series A
Preferred Stock or the Exchange Debentures, as the case may be, that are
Transfer Restricted Securities and to permit sales of Broker-Dealer
Transfer-Restricted Securities by Restricted Broker-Dealers as contemplated by
Section 3(c) below.

               (b) The Company shall cause the Exchange Offer Registration
Statement to be effective continuously, and shall keep the Exchange Offer open,
for a period of not less than the minimum period required under applicable
federal and state securities laws to Consummate the Exchange Offer; provided,
however, that in no event shall such period be less than 20 Business Days. The
Company shall cause the Exchange Offer to comply with all applicable federal and
state securities laws. No securities other than the New Preferred Stock and the
New Exchange Debentures shall be included in the Exchange Offer Registration
Statement. The Company shall use its best efforts to cause the Exchange Offer to
be Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30
Business Days thereafter.

                                       4
<PAGE>
 
               (c) The Company shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Restricted Broker- Dealer who holds Series A Preferred
Stock or Exchange Debentures that are Transfer Restricted Securities and that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities, may exchange such Series A Preferred
Stock or Exchange Debentures (other than Transfer Restricted Securities acquired
directly from the Company) pursuant to the Exchange Offer; however, such
Broker-Dealer may be deemed to be an "underwriter" within the meaning of the Act
and must, therefore, deliver a prospectus meeting the requirements of the Act in
connection with its initial sale of each New Preferred Stock or New Exchange
Debenture received by such Broker-Dealer in the Exchange Offer, which prospectus
delivery requirement may be satisfied by the delivery by such Broker-Dealer of
the Prospectus contained in the Exchange Offer Registration Statement. Such
"Plan of Distribution" section shall also contain all other information with
respect to such sales of Broker-Dealer Transfer Restricted Securities by
Restricted Broker-Dealers that the Commission may require in order to permit
such sales pursuant thereto, but such "Plan of Distribution" shall not name any
such Broker- Dealer or disclose the amount of Series A Preferred Stock or
Exchange Debentures held by any such Broker-Dealer except to the extent required
by the Commission as a result of a change in policy after the date of this
Agreement.

               The Company shall use its best efforts to keep the Exchange Offer
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) below to the extent necessary to
ensure that it is available for sales of Broker-Dealer Transfer Restricted
Securities by Restricted Broker-Dealers, and to ensure that such Registration
Statement conforms with the requirements of this Agreement, the Act and the
policies, rules and regulations of the Commission as announced from time to
time, for a period expiring on the earlier of (i) the date that all Holders of
Transfer Restricted Securities have registered such securities pursuant to the
Exchange Offer and (ii) 365 days from the date on which the Exchange Offer
Registration Statement is declared effective.

               The Company shall promptly provide sufficient copies of the
latest version of such Prospectus to such Restricted Broker-Dealers upon request
at any time during such 365-day period in order to facilitate such sales.


SECTION 4.            SHELF REGISTRATION

               (a) Shelf Registration. If (i) the Company is not required to
                   ------------------
file the Exchange Offer Registration Statement with respect to the New Preferred
Stock or the New Exchange Debentures or permitted to consummate the Exchange
Offer because the Exchange Offer is not permitted by applicable law or
Commission policy (after the procedures set forth in Section 6(a)(i) below have
been complied with) or (ii) any Holder of Transfer Restricted Securities
notifies the Company within 20 Business Days following the Consummation of the
Exchange Offer that (A) such Holder is prohibited by law or Commission policy
from participating in the Exchange Offer or (B) such Holder may not resell the
New Preferred Stock or New Exchange Debentures acquired by it in the Exchange
Offer to the public without delivering a prospectus and the Prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Series A Preferred Stock or Exchange Debentures acquired directly from the
Company or an affiliate of the Company, then the Company shall

                      (x) cause to be filed on or prior to (1) in the case of a
        Registration Statement filed pursuant to clause (i) above, 30 days after
        the date on which the Company determines that it is not required to file
        the Exchange Offer Registration Statement and (2) in the case of a
        Registration 

                                       5
<PAGE>
 
        Statement filed pursuant to clause (ii) above, 30 days after the date on
        which the Company receives the notice specified in clause (ii) above
        (and in any event, within 150 days after the Closing Date), a shelf
        registration statement pursuant to Rule 415 under the Act, (which may be
        an amendment to the Exchange Offer Registration Statement (in either
        event, the "Shelf Registration Statement")), relating to all Transfer
                    ----------------------------
        Restricted Securities the Holders of which shall have provided the
        information required pursuant to Section 4(b) hereof, and

                      (y) use its best efforts to cause such Shelf Registration
        Statement to become effective on or prior to (1) in the case of a
        Registration Statement filed pursuant to clause (i) above, 120 days
        after the date on which the Company becomes obligated to file such Shelf
        Registration Statement and (2) in the case of a Registration Statement
        filed pursuant to clause (ii) above, 120 days after the date on which
        the Company receives the notice specified in clause (ii) above (and in
        any event, within 240 days after the Closing Date). If, after the
        Company has filed an Exchange Offer Registration Statement which
        satisfies the requirements of Section 3(a) above, the Company is
        required to file and make effective a Shelf Registration Statement
        solely because the Exchange Offer is not permitted under applicable
        federal law, then the filing of the Exchange Offer Registration
        Statement shall be deemed to satisfy the requirements of clause (x)
        above. Such an event shall have no effect on the requirements of this
        clause (y), or on the Effectiveness Target Date as defined in Section 5
        below.

The Company shall use its best efforts to keep the Shelf Registration Statement
discussed in this Section 4(a) continuously effective, supplemented and amended
as required by the provisions of Sections 6(b) and (c) hereof to the extent
necessary to ensure that it is available for sales of Transfer Restricted
Securities by the Holders thereof entitled to the benefit of this Section 4(a),
and to ensure that it conforms with the requirements of this Agreement, the Act
and the policies, rules and regulations of the Commission as announced from time
to time, for a period expiring on the earlier of (i) the date that all Holders
of Transfer Restricted Securities have sold such securities pursuant to the
Exchange Offer and (ii) 365 days from the date on which the Exchange Offer
Registration Statement is declared effective.

               (b) Provision by Holders of Certain Information in Connection
                   ---------------------------------------------------------
with the Shelf Registration Statement. No Holder of Transfer Restricted

Registration Statement pursuant to this Agreement unless and until such Holder
furnishes to the Company in writing, within 20 Business Days after receipt of a
request therefor, such information specified in item 507 of Regulation S-K under
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to Liquidated Damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information required to be provided by such Holder for inclusion therein. Each
Holder as to which any Shelf Registration Statement is being effected agrees to
furnish promptly to the Company, for so long as the Registration Statement is
effective, all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.


SECTION 5.            LIQUIDATED DAMAGES

               If (i) the Company fails to file any of the Registration
Statements required by this Agreement on or before the date specified for such
filing in this Agreement, (ii) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Company fails to

Registration Statement or (iv) the Shelf Registration Statement or the Exchange
Offer Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in this Agreement without being succeeded within
the time period provided for herein by a post effective amendment to such
Registration Statement that cures such failure and that is itself declared
effective within ten Business Days of the filing thereof (each such event
referred to in clauses (i) through (iv) above, a "Registration Default"), then
                                                  --------------------
commencing on the day following the date on which such Registration Default
occurs, the Company agrees to pay to each Holder of Transfer Restricted
Securities affected by such Registration Default, for the first 90-day period
immediately following the occurrence of such Registration Default, liquidated

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

principal amount of Exchange Debentures constituting Transfer Restricted
Securities held by such Holder for each week or pro rata for a portion of each

per $100 Liquidation Preference of Series A Preferred Stock or $.05 per week per
$1,000 principal amount of Exchange Debentures constituting Transfer Restricted
Securities held by such Holder for each subsequent 90-day period until all

registered addresses by the Company on each Damages Payment Date. All
obligations of the Company set forth in the preceding paragraph that are
outstanding with respect to any Transfer Restricted Security at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such security shall have been
satisfied in full.

        Series A Preferred Stock or Exchange Debentures, as the case may be. The
        Company hereby agrees to pursue the issuance of such a decision to the
        Commission staff level. In connection with the foregoing, the Company
        hereby agrees to take all such other actions as are requested by the
        Commission or otherwise required in connection with the issuance of such
        decision, including without limitation (A) participating in telephonic
        conferences with the Commission, (B) delivering to the Commission staff

        bases, if any, upon which such counsel has concluded that such an
        Exchange Offer should be permitted and (C)

        diligently pursuing a resolution by the Commission staff of such
        submission. Nothing in this Section 6(a)(i) shall prevent the Company
        from promptly filing a Registration Statement in accordance with Section

                      (ii) As a condition to its participation in the Exchange
        Offer pursuant to the terms of this Agreement, each Holder of Transfer
        Restricted Securities shall furnish, upon the request of the Company,
        prior to the Consummation of the Exchange Offer, a written

        to the effect that (A) it is not an affiliate of the Company, (B) it is
        not engaged in, and does not intend to engage in, and has no arrangement
        or understanding with any person to participate in, a distribution of
        the New Preferred Stock or New Exchange Debentures to be issued in the
        Exchange Offer and (C) it is acquiring the New Preferred Stock or New
        Exchange Debentures in its ordinary course of business. Each Holder
        hereby acknowledges and agrees that any Broker-Dealer and any such
        Holder using the Exchange Offer to participate in a distribution of the
        securities to be acquired in the Exchange Offer (1) could not under
        Commission policy as in effect on the date of this Agreement rely on the
        position of the Commission enunciated in Morgan Stanley and Co., Inc.

Statement and any related Prospectus required by this Agreement to permit the
sale or resale of Transfer Restricted Securities (including, without limitation,
any Exchange Offer Registration Statement and the related Prospectus, to the
extent that the same are required to be available to permit sales of

Company shall:

                      (i) use its best efforts to keep such Registration
        Statement continuously effective and provide all requisite financial
        statements for the period specified in Section 3 or 4 of this Agreement,
        as applicable. Upon the occurrence of any event that would cause any

        contain a material misstatement or omission or (B) not to be effective
        and usable for resale of Transfer Restricted Securities during the
        period required by this Agreement, the Company shall file promptly an
        appropriate amendment to such Registration Statement (1) in the case of
        clause (A), correcting any such misstatement or omission, and (2) in the
        case of either clause (A) or (B), use its best efforts to cause such
        amendment to be declared effective and such Registration Statement and
        the related Prospectus to become usable for their intended purpose(s) as
        soon as practicable thereafter;

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

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

                                       9

        of the Registration Statement, or any state securities commission or
        other regulatory authority shall issue an order suspending the
        qualification or exemption from qualification of the Transfer Restricted
        Securities under state securities or Blue Sky laws, the Company shall
        use its best efforts to obtain the withdrawal or lifting of such order
        at the earliest possible time;

                      (iv) make available to each selling Holder named in any
        Registration Statement or Prospectus and each of the underwriter(s) in
        connection with such sale, if any, before filing with the Commission,
        copies of any Registration Statement or any Prospectus included therein
        or any amendments or supplements to any such Registration Statement or
        Prospectus (including all documents incorporated by reference after the
        initial filing of such Registration Statement), which documents will be
        subject to the review and comment of such Holders and underwriter(s) in
        connection with such sale, if any, for a period of at least five
        Business Days, and the Company will not file any such Registration
        Statement or Prospectus or any amendment or supplement to any such
        Registration Statement or Prospectus (including all such documents
        incorporated by reference) to which the selling Holders of the Transfer
        Restricted Securities covered by such Registration Statement or the
        underwriter(s) in connection with such sale, if any, shall reasonably
        object within five Business Days after the receipt thereof. A selling
        Holder or underwriter, if any, shall be deemed to have reasonably
        objected to such filing if such Registration Statement, amendment,
        Prospectus or supplement, as applicable, as proposed to be filed,
        contains a material misstatement or omission or fails to comply with the
        applicable requirements of the Act;

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

                      (vi) make available at reasonable times for inspection by
        the selling Holders, any underwriter participating in any disposition
        pursuant to such Registration Statement and any attorney or accountant
        retained by such selling Holders or any of such underwriter(s), all
        financial and other records, pertinent corporate documents and
        properties of the Company and cause the Company's officers, directors
        and employees to supply all information reasonably requested by any such
        Holder, underwriter, attorney or accountant in connection with such
        Registration Statement or any post-effective amendment thereto
        subsequent to the filing thereof and prior to its effectiveness;
        provided that any person to whom information is provided under this
        clause (vi) agrees in writing to maintain the confidentiality of such
        information to the extent such information is not in the public domain;

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

                      (viii) cause the Transfer Restricted Securities covered by
        the Registration Statement to be rated with the appropriate rating
        agencies, if so requested by the Holders of a majority in aggregate
        Liquidation Preference of Series A Preferred Stock or aggregate
        principal amount of Exchange Debentures, as the case may be, covered
        thereby or the underwriter(s), if any;

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

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

                      (xi) enter into such agreements (including, unless not
        required pursuant to Section 10 hereof, an underwriting agreement) and
        make such representations and warranties and take all such other actions
        in connection therewith in order to expedite or facilitate the
        disposition of the Transfer Restricted Securities pursuant to any
        Registration Statement contemplated by this Agreement as may be
        reasonably requested by any Holder of Transfer Restricted Securities or
        underwriter in connection with any sale or resale pursuant to any
        Registration Statement contemplated by this Agreement, and in such
        connection, whether or not an underwriting agreement is entered into and
        whether or not the registration is an Underwritten Registration, the
        Company shall:

                      (A) furnish to each selling Holder and each underwriter,

                      of the Shelf Registration Statement or the date of
                      Consummation of the Exchange Offer, as the case may be,
                      signed by (x) the President or any Vice President and (y)
                      a principal financial or accounting officer of the
                      Company, confirming, as of the date thereof, the matters
                      set forth in paragraphs (a), (b), (c) and (d) of Section 8
                      of the Purchase Agreement and such other matters as the
                      Holders and/or underwriter(s) may reasonably request;

                      the Shelf Registration Statement or the date of
                      Consummation of the Exchange Offer, as the case may be, of
                      counsel for the Company, covering (i) due authorization
                      and enforceability of the Series A Preferred Stock, the
                      New Preferred Stock, the Exchange Debentures and the New
                      Exchange Debentures, (ii) a statement to the effect that
                      such counsel has participated in conferences with officers
                      and other representatives of the Company and
                      representatives of the independent public accountants for
                      the Company and have considered the matters required to be
                      stated therein and the statements contained therein,
                      although such counsel has not independently verified the
                      accuracy, completeness or fairness of such statements; and
                      that such counsel advises that, on the basis of the
                      foregoing (relying as to materiality to a large extent
                      upon facts 

                                       11
<PAGE>
 
                      provided to such counsel by officers and other
                      representatives of the Company and without independent
                      check or verification), no facts came to such counsel's
                      attention that caused such counsel to believe that the
                      applicable Registration Statement, at the time such
                      Registration Statement or any post-effective amendment
                      thereto became effective, and, in the case of the Exchange
                      Offer Registration Statement, as of the date of
                      Consummation, contained an untrue statement of a material
                      fact or omitted to state a material fact required to be
                      stated therein or necessary to make the statements therein
                      not misleading, or that the Prospectus contained in such
                      Registration Statement as of its date and, in the case of
                      the opinion dated the date of Consummation of the Exchange
                      Offer, as of the date of Consummation, contained an untrue
                      statement of a material fact or omitted to state a
                      material fact necessary in order to make the statements
                      therein, in the light of the circumstances under which
                      they were made, not misleading and (iii) such other
                      matters of the type customarily covered in opinions of
                      counsel for an issuer in connection with similar
                      securities offerings, as may reasonably be requested by
                      such parties. Without limiting the foregoing, such counsel
                      may state further that such counsel assumes no
                      responsibility for, and has not independently verified,
                      the accuracy, completeness or fairness of the financial
                      statements, notes and schedules and other financial,
                      statistical and accounting data included in any
                      Registration Statement contemplated by this Agreement or
                      the related Prospectus; and

                             (3) a customary comfort letter, dated as of the
                      date of effectiveness of the Shelf Registration Statement
                      or the date of Consummation of the Exchange Offer, as the
                      case may be, from the Company's independent accountants,
                      in the customary form and covering matters of the type
                      customarily covered in comfort letters to underwriters in
                      connection with primary underwritten offerings, and
                      affirming the matters set forth in the comfort letters
                      delivered pursuant to Section 8(i) of the Purchase
                      Agreement, without exception;

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

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

               The above shall be done at each closing under such underwriting
        or similar agreement, as and to the extent required thereunder, and if
        at any time the representations and warranties of the Company
        contemplated in (A)(1) above cease to be true and correct, the Company
        shall so advise the underwriter(s), if any, and selling Holders promptly
        and if requested by such Persons, shall confirm such advice in writing;

                      (xii) prior to any public offering of Transfer Restricted
        Securities, cooperate with the selling Holders, the underwriter(s), if
        any, and their respective counsel in connection with the registration
        and qualification of the Transfer Restricted Securities under the
        securities or Blue Sky 

                                       12
<PAGE>
 
        laws of such jurisdictions as the selling Holders or underwriter(s), if
        any, may request and do any and all other acts or things necessary or
        advisable to enable the disposition in such jurisdictions of the
        Transfer Restricted Securities covered by the applicable Registration
        Statement; provided, however, that the Company shall not be required to
        register or qualify as a foreign corporation where it is not now so
        qualified or to take any action that would subject it to the service of
        process in suits or to taxation, other than as to matters and
        transactions relating to the Registration Statement, in any jurisdiction
        where it is not now so subject;

                      (xiii) issue, upon the request of any Holder of Series A
        Preferred Stock or covered by any Shelf Registration Statement
        contemplated by this Agreement, New Preferred Stock or New Exchange
        Debentures, as the case may be, having an aggregate Liquidation
        Preference or an aggregate principal amount, as the case may be, equal
        to the aggregate Liquidation Preference of Series A Preferred Stock or
        the aggregate principal amount of Exchange Debentures, as the case may
        be, surrendered to the Company by such Holder in exchange therefor or
        being sold by such Holder; such New Preferred Stock or New Exchange
        Debentures to be registered in the name of such Holder or in the name of
        the purchaser(s) of such New Preferred Stock or New Exchange Debentures,
        as the case may be; in return, the Series A Preferred Stock or Exchange
        Debentures, as the case may be, held by such Holder shall be surrendered
        to the Company for cancellation;

                      (xiv) in connection with any sale of Transfer Restricted
        Securities that will result in such securities no longer being Transfer
        Restricted Securities, cooperate with the selling Holders and the
        underwriter(s), if any, to facilitate the timely preparation and
        delivery of certificates representing Transfer Restricted Securities to
        be sold and not bearing any restrictive legends; and to register such
        Transfer Restricted Securities in such denominations and such names as
        the Holders or the underwriter(s), if any, may request at least two
        Business Days prior to such sale of Transfer Restricted Securities;

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

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

                      (xvii) provide a CUSIP number for all Transfer Restricted
        Securities not later than the effective date of a Registration Statement
        covering such Transfer Restricted Securities and provide the Transfer
        Agent or the Trustee, as the case may be, with printed certificates for
        the Transfer Restricted Securities which are in a form eligible for
        deposit with the Depository Trust Company;

                      (xviii) cooperate and assist in any filings required to be
        made with the NASD and in the performance of any due diligence
        investigation by any underwriter (including any "qualified 

                                       13
<PAGE>
 
        independent underwriter") that is required to be retained in accordance
        with the rules and regulations of the NASD, and use its best efforts to
        cause such Registration Statement to become effective and approved by
        such governmental agencies or authorities as may be necessary to enable
        the Holders selling Transfer Restricted Securities to consummate the
        disposition of such Transfer Restricted Securities;

                      (xix) otherwise use its best efforts to comply with all
        applicable rules and regulations of the Commission, and make generally
        available to its security holders with regard to any applicable
        Registration Statement, as soon as practicable, a consolidated earnings
        statement meeting the requirements of Rule 158 (which need not be
        audited) covering a twelve-month period beginning after the effective
        date of the Registration Statement (as such term is defined in paragraph
        (c) of Rule 158 under the Act);

                      (xx) in the event such Transfer Restricted Securities are
        Exchange Debentures, cause the Indenture to be qualified under the TIA
        not later than (a) the date on which the Series A Preferred Stock is
        exchanged for Exchange Debentures or (b) the effective date of the first
        Registration Statement relating to the Exchange Debentures required by
        this Agreement, and, in connection therewith, cooperate with the Trustee
        and the Holders of Exchange Debentures to effect such changes to the
        Indenture as may be required for such Indenture to be so qualified in
        accordance with the terms of the TIA; and execute and use its best
        efforts to cause the Trustee to execute, all documents that may be
        required to effect such changes and all other forms and documents
        required to be filed with the Commission to enable such Indenture to be
        so qualified in a timely manner;

                      (xxi) use its best efforts to obtain at its annual meeting
        of shareholders to be held in 1997 any necessary shareholder consents to
        increase the number of shares of Series A Preferred Stock and New
        Preferred Stock authorized for issuance in order to (a) enable the
        holders of Series A Preferred Stock with a Liquidation Preference of
        $10,000 per share to exchange such shares for New Preferred Stock with a
        Liquidation Preference of $1,000 per share in the Exchange Offer or, if
        such exchange has already occurred, (b) effect a ten for one stock split
        of the New Preferred Stock;

                      (xxii) cause all Transfer Restricted Securities covered by
        the Registration Statement to be listed on each securities exchange on
        which similar securities issued by the Company are then listed if
        requested by the Holders of a majority in aggregate Liquidation
        Preference of Series A Preferred Stock or aggregate principal amount of
        Exchange Debentures or the managing underwriter(s), if any;

                      (xxiii) provide promptly to each Holder upon written
        request each document filed with the Commission pursuant to the
        requirements of Section 13 or Section 15(d) of the Exchange Act; and

               (d) Restrictions on Holders. Each Holder agrees by acquisition of
                   -----------------------
a Transfer Restricted Security that, upon receipt of any notice from the Company
of the existence of any fact of the kind described in Section 6(c)(iii)(D)
hereof, such Holder will forthwith discontinue disposition of Transfer
Restricted Securities pursuant to the applicable Registration Statement until
such Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 6(c)(xvi) hereof, or until it is advised in writing (the
"Advice") by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings that are incorporated
by reference in the Prospectus. If so directed by the Company, each Holder will
deliver to the Company (at the Company's expense) all copies, other than

                                       14
<PAGE>
 
permanent file copies then in such Holder's possession, of the Prospectus
covering such Transfer Restricted Securities that was current at the time of
receipt of such notice. In the event the Company shall give any such notice, the
time period regarding the effectiveness of such Registration Statement set forth
in Section 3 or 4 hereof, as applicable, shall be extended by the number of days
during the period from and including the date of the giving of such notice
pursuant to Section 6(c)(iii)(D) hereof to and including the date when each
selling Holder covered by such Registration Statement shall have received the
copies of the supplemented or amended Prospectus contemplated by Section
6(c)(xvi) hereof or shall have received the Advice.


SECTION 7.            REGISTRATION EXPENSES

               (a) All expenses incident to the Company's performance of or
compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses (including filings
made with the NASD (including, if applicable, the fees and expenses (excluding
underwriting discounts or commissions) of any "qualified independent
underwriter" and its counsel, as may be required by the rules and regulations of
the NASD)); (ii) all fees and expenses of compliance with federal securities and
state Blue Sky or securities laws; (iii) all expenses of printing (including
printing certificates for the New Preferred Stock or New Exchange Debentures and
printing of Prospectuses), messenger and delivery services and telephone; (iv)
all fees and disbursements of counsel for the Company and, in accordance with
Section 7(b) below, the Holders of Transfer Restricted Securities; (v) all
application and filing fees in connection with listing the New Preferred Stock
or New Exchange Debentures on a national exchange or automated quotation system
if required hereunder; and (vi) all fees and disbursements of independent
certified public accountants of the Company (including the expenses of any
special audit and comfort letters required by or incident to such performance).

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

               (b) In connection with any Registration Statement required by
this Agreement, the Company will reimburse the Holders of Transfer Restricted
Securities being tendered in the Exchange Offer and/or resold pursuant to the
"Plan of Distribution" contained in the Exchange Offer Registration Statement or
registered pursuant to the Shelf Registration Statement, as applicable, for the
reasonable fees and disbursements of not more than one counsel chosen by the
Holders of a majority in Liquidation Preference or principal amount of the
Transfer Restricted Securities for whose benefit such Registration Statement is
being prepared.


SECTION 8.            INDEMNIFICATION

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

                                       15
<PAGE>
 
otherwise, insofar as such losses, liabilities, claims, damages or expenses (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the Registration
Statement or the Prospectus, or in any supplement thereto or amendment thereof,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that the Company will not be liable in
any such case to the extent, but only to the extent, that (i) any such loss,
liability, claim, damage or expense arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder expressly for use
therein and (ii) the foregoing indemnity with respect to any untrue statement
contained in or omitted from a Registration Statement or the Prospectus shall
not inure to the benefit of any Holder (or any person controlling such Holder),
from whom the person asserting any such loss, liability, claim, damage or
expense purchased any of the Series A Preferred Stock, New Preferred Stock,
Exchange Debentures or New Exchange Debentures, as the case may be, which are
the subject thereof if it is finally judicially determined that such loss,
liability, claim, damage or expense resulted solely from the fact that the
Holder sold Series A Preferred Stock, New Preferred Stock, Exchange Debentures
or New Exchange Debentures, as the case may be, to a person to whom there was
not sent or given, at or prior to the written confirmation of such sale, a copy
of the Registration Statement and the Prospectus, as amended or supplemented,
and (x) the Company shall have previously and timely furnished sufficient copies
of the Registration Statement or Prospectus, as so amended or Supplemented, to
such Holder in accordance with this Agreement and (y) the Registration Statement
or Prospectus, as so amended or supplemented, would have corrected such untrue
statement or omission of a material fact. This indemnity agreement will be in
addition to any liability which the Company may otherwise have, including, under
this Agreement.

               (b) Each Holder, severally and not jointly, agrees to indemnify
and hold harmless the Company and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act, against any losses, liabilities, claims, damages and expenses whatsoever
(including but not limited to attorneys' fees and any and all expenses
whatsoever incurred in investigating, preparing or defending against any
investigation or litigation, commenced or threatened, or any claim whatsoever
and any and all amounts paid in settlement of any claim or litigation), joint or
several, to which they or any of them may become subject under the Act, the
Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages
or expenses (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement or the Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, in each case to the extent, but only
to the extent, that any such loss, liability, claim, damage or expense arises
out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made therein in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such Holder
expressly for use therein. This indemnity will be in addition to any liability
which a Holder may otherwise have, including under this Agreement. In no event,
however, shall the liability of any selling Holder hereunder be greater in
amount than the dollar amount of the proceeds received by such Holder upon its
sale of the Series A Preferred Stock, New Preferred Stock, Exchange Debenture or
New Exchange Debenture giving rise to such indemnification obligation.

               (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify each party against whom
indemnification 

                                       16
<PAGE>
 
is to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 8 except to the extent that it has been prejudiced
in any material respect by such failure or from any liability which it may
otherwise have). In case any such action is brought against any indemnified
party, and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein, and to the extent it
may elect by written notice delivered to the indemnified party promptly after
receiving the aforesaid notice from such indemnified party, to assume the
defense thereof with counsel reasonably satisfactory to such indemnified party.
Notwithstanding the foregoing, the indemnified party or parties shall have the
right to employ its or their own counsel in any such case, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties unless (i) the employment of such counsel shall have been authorized in
writing by the indemnifying parties in connection with the defense of such
action, (ii) the indemnifying parties shall not have employed counsel to take
charge of the defense of such action within a reasonable time after notice of
commencement of the action, or (iii) such indemnified party or parties shall
have reasonably concluded that there may be defenses available to it or them
which are different from or additional to those available to one or all of the
indemnifying parties (in which case the indemnifying party or parties shall not
have the right to direct the defense of such action on behalf of the indemnified
party or parties), in any of which events such fees and expenses of counsel
shall be borne by the indemnifying parties; provided, however, that the
indemnifying party under subsection (a) or (b) above, shall only be liable for
the legal expenses of one counsel (in addition to any local counsel) for all
indemnified parties in each jurisdiction in which any claim or action is
brought. Anything in this subsection to the contrary notwithstanding, an
indemnifying party shall not be liable for any settlement of any claim or action
effected without its prior written consent; provided, however, that such consent
was not unreasonably withheld.

               (d) In order to provide for contribution in circumstances in
which the indemnification provided for in this Section 8 is for any reason held
to be unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company and each Holder shall contribute to the
aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including any investigation,
legal and other expenses incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claims asserted, but after
deducting in the case of losses, claims, damages, liabilities and expenses
suffered by the Company, any contribution received by the Company from persons,
other than the Holders, who may also be liable for contribution, including
persons who control the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act) to which the Company and any Holder may be
subject, in such proportion as is appropriate to reflect the relative benefits
received by the Company from the offering of Series A Preferred Stock, New
Preferred Stock, Exchange Debentures or New Exchange Debentures, as the case may
be, and any such Holder from its sale of Series A Preferred Stock, New Preferred
Stock, Exchange Debentures or New Exchange Debentures, as the case may be, or,
if such allocation is not permitted by applicable law or indemnification is not
available as a result of the indemnifying party not having received notice as
provided in this Section 8, in such proportion as is appropriate to reflect not
only the relative benefits referred to above but also the relative fault of the
Company and the Holders in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative benefits received by
the Company and any Holder shall be deemed to be in the same proportion as (x)
the total proceeds from the offering (net of discounts but before deducting
expenses) of the Series A Preferred Stock, New Preferred Stock, Exchange
Debentures or New Exchange Debentures, as the case may be, received by the
Company and (y) the total proceeds received by such Holder upon its sale of
Series A Preferred Stock, New Preferred Stock, Exchange Debentures or New
Exchange Debentures, as the case may be, which would otherwise give rise to the
indemnification obligation, respectively. The relative fault of the Company and
of the Holders shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a

                                       17
<PAGE>
 
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Holders and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and each Holder agree that it
would not be just and equitable if contribution pursuant to this Section 8 were
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to above.
Notwithstanding the provisions of this Section 8, (i) no Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of its Series A
Preferred Stock, New Preferred Stock, Exchange Debentures or New Exchange
Debentures, as the case may be, exceeds the sum of (A) the amount paid by such
Holder for such Series A Preferred Stock, New Preferred Stock, Exchange
Debentures or New Exchange Debentures, as the case may be, plus (B) the amount
of any damages which such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission and (ii)
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 8, (A)
each person, if any, who controls a Holder within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act and (B) the respective officers,
directors, partners, employees, representatives and agents of a Holder or any
controlling person shall have the same rights to contribution as such Holder,
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to
contribution as the Company, subject in each case to clauses (i) and (ii) of
this Section 8(d). Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim for contribution may be made against another
party or parties under this Section 8, notify such party or parties from whom
contribution may be sought, but the failure to so notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any obligation it or they may have under this Section 8 or otherwise. No party
shall be liable for contribution with respect to any action or claim settled
without its prior written consent; provided, however, that such written consent
was not unreasonably withheld.


SECTION 9.            RULE 144A

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


SECTION 10.           UNDERWRITTEN REGISTRATIONS

               The Holders of Transfer Restricted Securities may elect to sell
their Transfer Restricted Securities pursuant to one or more Underwritten
Registrations; provided, however, that in no event shall any Holder commence any
such Underwritten Registration if a period of less than 180 days has elapsed
since the consummation of the most recent Underwritten Registration hereunder;
and provided further that in no event shall the Holders effect more than three
such Underwritten Registrations hereunder. No Holder may participate in any
Underwritten Registration hereunder unless such Holder (a) agrees to sell such
Holder's Transfer Restricted Securities on the basis provided in customary
underwriting arrangements entered into in connection therewith and (b) completes
and executes all reasonable questionnaires, powers of attorney, 

                                       18
<PAGE>
 
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such underwriting arrangements.


SECTION 11.           SELECTION OF UNDERWRITERS

               In any Underwritten Offering, the investment banker or investment
bankers and manager or managers that will administer the offering will be
selected by the Holders of a majority in aggregate Liquidation Preference or
aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
reasonably satisfactory to the Company. Such investment bankers and managers are
referred to herein as the "underwriters."


SECTION 12.           MISCELLANEOUS

               (a) Remedies. Each Holder, in addition to being entitled to
                   --------
exercise all rights provided herein, in the Certificate of Designation, the
Indenture, the Purchase Agreement or granted by law, including recovery of
liquidated or other damages, will be entitled to specific performance of its
rights under this Agreement. The Company agrees that monetary damages (including
the Liquidated Damages contemplated hereby) would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this
Agreement and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

               (b) No Inconsistent Agreements. The Company will not on or after
                   --------------------------
the date of this Agreement enter into any agreement with respect to its
securities that conflicts with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof, except where a waiver with
respect thereto has been obtained prior to the date of effectiveness of any
registration statement required under this Agreement.

               (c) Adjustments Affecting the Series A Preferred Stock or
                   -----------------------------------------------------
Exchange Debentures. The Company will not take any action, or permit any change
- -------------------
to occur, with respect to the Series A Preferred Stock or Exchange Debentures
that would materially adversely affect the ability of the Holders to Consummate
any Exchange Offer.

               (d) Amendments and Waivers. The provisions of this Agreement may
                   ----------------------
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless the Company has
obtained the written consent of Holders of a majority of the outstanding
Liquidation Preference or principal amount of Transfer Restricted Securities.
Notwithstanding the foregoing, a waiver or consent to departure from the
provisions hereof that relates exclusively to the rights of Holders whose
securities are being tendered pursuant to the Exchange Offer and that does not
