                 THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M.,
             NEW YORK CITY TIME, ON       , 1996, UNLESS EXTENDED
                                ---------------
 
  Hyperion Telecommunications, Inc. ("Hyperion" or the "Company") hereby
offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying Letter of Transmittal (which together
constitute the "Exchange Offer"), to exchange $1,000 principal amount of 13%
Series B Senior Discount Notes of the Company (the "New Notes") for each
$1,000 principal amount of the issued and outstanding 13% Senior Discount
Notes due 2003 (the "Old Notes," and collectively with the New Notes, the
"Senior Notes"). As of the date of this Prospectus, $329,000,000 aggregate
principal amount at maturity of the Old Notes is outstanding. The terms of the
New Notes and the Old Notes are substantially identical in all material
respects, except for certain transfer restrictions and registration rights;
and except that holders of Old Notes are entitled to receive Liquidated
Damages (as defined) if (a) the Company fails to file any of the registration
statements required by the Registration Rights Agreement (as defined) on or
before the date specified for such filing, (b) any of such registration
statements is not declared effective by the Securities and Exchange Commission
(the "Commission") on or prior to the date specified for such effectiveness
(the "Effectiveness Target Date"), (c) the Company fails to consummate the
Exchange Offer within 30 business days of the Effectiveness Target Date with
respect to the Exchange Offer registration statement, or (d) a shelf
registration statement or the registration statement of which this Prospectus
forms a part (the "Exchange Offer Registration Statement") is declared
effective but thereafter ceases to be effective or usable in connection with
resales of Transfer Restricted Securities (as defined) during the periods
specified in the Registration Rights Agreement (each such event referred to in
clauses (a) through (d) above a "Registration Default"). In the event of a
Registration Default, the Company is required to pay Liquidated Damages to
each holder of Transfer Restricted Securities, with respect to the first 90-
day period immediately following the occurrence of such Registration Default,
at a rate of 0.5% per annum, determined daily, on the Accreted Value of the
Senior Notes (or after April 15, 2001, on the principal amount of the Senior
Notes) as of the immediately preceding interest payment date. Such interest
rate will increase by an additional 0.25% per annum at the beginning of each
subsequent 90-day period up to a maximum aggregate increase of 2.0% per annum
until all Registration Defaults have been cured, at which time the accrual
rate borne by the Old Notes will be reduced to the original accrual rate. See
"Description of Senior Notes--Registration Rights; Liquidated Damages."
 
  The Exchange Offer is being made to satisfy certain obligations of the
Company under the Registration Rights Agreement, dated as of April 15, 1996,
among the Company and the Initial Purchasers (the "Registration Rights
Agreement"). Upon consummation of the Exchange Offer, holders of Old Notes
that were not prohibited from participating in the Exchange Offer and did not
tender their Old Notes will not have any registration rights under the
Registration Rights Agreement with respect to such nontendered Old Notes and,
accordingly, such Old Notes will continue to be subject to the restrictions on
transfer contained in the legend thereon.
 
  Based on interpretations by the staff of the Commission with respect to
similar transactions, the Company believes that the New Notes issued pursuant
to the Exchange Offer in exchange for Old Notes may be offered for resale,
resold and otherwise transferred by any holder of such New Notes (other than
any such holder which is an "affiliate" of Hyperion within the meaning of Rule
405 under the Securities Act of 1933, as amended (the "Securities Act"))
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such New Notes are acquired in the ordinary
course of such holder's business, such holder has no arrangement or
understanding with any person to participate in the distribution of such New
Notes and neither the holder nor any other person is engaging in or intends to
engage in a distribution of the New Notes. Each broker-dealer that receives
New Notes for its own account in exchange for Old Notes must acknowledge that
it will deliver a prospectus in connection with any resale of its New Notes.
The Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of the New Notes received in exchange for
the Old Notes acquired by the broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that it will
make this Prospectus available to any broker-dealer for use in connection with
any such resale for a period of 365 days after the Exchange Date (as defined)
or, if earlier, until all participating broker-dealers have so resold. See
"Plan of Distribution."

     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION

  The New Notes will evidence the same debt as the Old Notes and will be
entitled to the benefits of the Indenture (as defined). For a more complete
description of the terms of the New Notes, see "Description of Senior Notes."
There will be no cash proceeds to the Company from the Exchange Offer. The New
Notes will be general obligations of the Company exclusively, will not be
secured by any assets of the Company, its Subsidiaries (as defined) or Joint
Ventures (as defined), will rank pari passu in right of payment with all
existing and future senior Indebtedness (as defined) of the Company and will
rank senior in right of payment to future subordinated Indebtedness of the
Company; however, because the Company is a holding company that conducts
substantially all of its business through its Subsidiaries and its Joint
Ventures, the New Notes will be effectively subordinated to all liabilities of
the Subsidiaries and Joint Ventures, including trade payables and indebtedness
incurred by its Subsidiaries and Joint Ventures.
 
  The Old Notes were originally issued and sold on April 15, 1996 in the
Offering (as defined), a transaction exempt from registration under the
Securities Act in reliance upon the exemptions provided by Rule 144A and by
Section 4(2) of the Securities Act. Accordingly, the Old Notes may not be
reoffered, resold or otherwise pledged, hypothecated or transferred in the
United States unless so registered or unless an exemption from the
registration requirements of the Securities Act and applicable state
securities laws is available.
 
  The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and
to the best of the Company's information and belief, each person participating
in the Exchange Offer is acquiring the New Notes in its ordinary course of
business and has no arrangement or understanding with any person to
participate in the distribution of the New Notes to be received in the
Exchange Offer.
 
  The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered for exchange. The Exchange Offer will
expire at 5:00 p.m., New York City time, on       , 1996, unless extended (as
it may be so extended, the "Expiration Date"), provided that the Exchange
Offer shall not be extended beyond 30 business days from the date of this
Prospectus. The date of acceptance for exchange of the Old Notes for the New
Notes (the "Exchange Date") will be the first business day following the
Expiration Date. Old Notes tendered pursuant to the Exchange Offer may be
withdrawn at any time prior to the Expiration Date; otherwise such tenders are
irrevocable.
 
  Prior to this Exchange Offer, there has been no public market for the Senior
Notes. The Old Notes have traded on the PORTAL Market. If a market for the New
Notes should develop, the New Notes could trade at a discount from their
initial offering price. The Company does not intend to apply for listing of
the New Notes on any securities exchange or in any automated quotation system.
There can be no assurance that an active trading market for the New Notes will
develop.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information, including the consolidated Financial Statements and Notes thereto,
appearing elsewhere in this Prospectus. For a description of certain terms used
in this Prospectus, see the Glossary attached to this Prospectus as Appendix A.
This Prospectus contains certain statements of a forward-looking nature
relating to future events or the future financial performance of the Company.
Persons participating in this Exchange Offer are cautioned that such statements
are only predictions and that actual events or results may differ materially.
In evaluating such statements, participants in the Exchange Offer should
specifically consider the various factors identified in this Prospectus,
including the matters set forth under the caption "Risk Factors," which could
cause actual results to differ materially from those indicated by such forward-
looking statements. References in this Offering Memorandum to the "Company" or
"Hyperion" mean Hyperion Telecommunications, Inc. together with its
subsidiaries, except where the context otherwise requires. Unless the context
otherwise requires, references herein to the "networks," the "Company's
networks" or the "Operating Companies' networks" mean the 13 telecommunications
networks owned by 11 Operating Companies (which, as defined herein, are (i)
wholly owned subsidiaries of the Company and (ii) joint venture partnerships
and corporations managed by the Company and in which the Company holds less
than a majority equity interest with one or more other partners). See "--
Company and Partnership Ownership." Currently, nine of the Operating Companies
(comprising 11 of the 13 networks) are partnerships that are 50% or less owned
by the Company, and the Operating Companies do not include the South Florida
Partnership (as defined herein). As described more fully herein, the Company
designs, constructs, manages and operates networks on behalf of the Operating
Companies, and it is through these networks that the Company and the Operating
Companies provide telecommunications services. Unless otherwise indicated, the
information in this Prospectus gives effect to a 10,000-to-one stock split on
April 8, 1996 of each outstanding share of the Company's Common Stock (as
defined).
 
                                  THE COMPANY
 
  Hyperion Telecommunications, Inc. ("Hyperion" or the "Company") is a leading
competitive local exchange carrier ("CLEC") that designs, constructs, operates
and manages state-of-the-art fiber optic networks and facilities. According to
industry data, the Company believes it operates one of the three largest CLECs
in the United States based upon route miles and buildings connected. The
Company's networks work in conjunction with interexchange carriers ("IXCs")
such as AT&T, MCI, Sprint, WorldCom and others in order to offer small, medium
and large businesses, government and education end users a broad array of
integrated, high quality voice, video and enhanced data communications
services. The Company, through its 13 networks, currently offers traditional
access services, including high capacity interconnection between (i) points of
presence ("POPs") of an IXC, (ii) the POPs of different IXCs, (iii) a Local
Exchange Carrier's Central Office ("LEC-CO") and IXC POPs, (iv) end users and
their selected IXCs and (v) different locations of particular customers
("Private Line Services"). The Company has also installed switches or remote
switching capability in five of its networks and plans to offer switched
services, including customer dial tone, in all of its operating markets by the
end of 1996. Three of the Company's networks also offer enhanced data services
to their customers such as frame relay, Asynchronous Transfer Mode ("ATM") data
transport, business video conferencing, private line data interconnect service
and LAN connection and monitoring services in certain markets in a partnership
with !NTERPRISE, a wholly-owned subsidiary of US West. These services, along
with the long distance services provided by IXCs, enable the Company to provide
an integrated telecommunications service offering to network customers that is
more reliable, has a superior level of service and is priced lower relative to
that of the incumbent local exchange carriers ("LECs") in markets served by the
Company's networks.
 
  The Company currently manages and operates 13 networks which are primarily
clustered in three regions located in the eastern half of the United States and
which serve 19 cities with populations from at least 25,000 to more than
600,000. The Company also has four new networks under construction which will
serve 17 additional cities and which the Company will manage and operate upon
their expected completion in calendar year 1996. Eleven of the Company's
operating networks and three of its networks under construction are owned in
 
                                       2
<PAGE>
 
partnership with several major cable television operators, including Tele-
Communications, Inc., Time Warner/Newhouse, Continental Cablevision, TKR Cable,
Lenfest Communications, Viacom, InterMedia Partners and Multimedia/Gannett, and
an electric utility, PECO Energy, owner of the Philadelphia Electric Company
(collectively, the "Local Partners"). The Company believes that working with a
Local Partner significantly reduces the cost and time in developing a network
through the utilization of existing cable or utility facilities. The remaining
two operating networks and one network under construction are wholly-owned by
the Company and lease fiber capacity from Adelphia Communications Corporation
("Adelphia"), the Company's corporate parent, to achieve similar time and cost
savings in developing the networks.
 
  The Company intends to increase the density of its existing network clusters
and expand into new geographic markets or clusters through the construction of
approximately ten new networks by the end of 1997. From the Company's inception
in October 1991 through December 31, 1995, the Company and its partners have
invested approximately $147 million to build and develop the network
infrastructure and operations. As of February 29, 1996, the Company's 13
operating networks served 19 cities, and along with the four networks under
construction, included approximately 2,180 route miles of fiber optic cable and
were connected to approximately 808 buildings. For the nine months ended
December 31, 1995, the Company's 13 networks generated total revenues of
approximately $5.5 million. The Company reports its interest in joint ventures
pursuant to the equity method of accounting on a basis consistent with
generally accepted accounting principles. The Company's revenues and EBITDA
were approximately $2.5 million and ($1.8) million, respectively, for the nine
months ended December 31, 1995.
 
  The Company believes the passage of the Telecommunications Act of 1996 (the
"Telecommunications Act") on February 8, 1996 will substantially expand the
market opportunities for the Company and its networks. The Telecommunications
Act provides for the removal of legal barriers to entering the local exchange
telecommunications market and directs the incumbent LECs to negotiate with
CLECs to resolve network and competitive issues such as interconnection of CLEC
and incumbent LEC networks, reciprocal compensation for termination of calls
originating on a competing network, telephone number portability, access to
rights-of-way and the unbundling of network services. The Telecommunications
Act may provide an incentive for incumbent LECs to cooperate with local
facilities-based competitors, such as the Company, on interconnection issues
because the existence of an interconnection agreement with a facilities-based
competitor is a prerequisite for incumbent LEC entry into the long distance
market unless no such facilities-based competitor has requested access and
interconnection in accordance with the terms of the Telecommunications Act.
Based upon data compiled by the Federal Communications Commission (the "FCC"),
the Company believes that the passage of the Telecommunications Act increases
the potential market for CLECs from approximately $26.3 billion to
approximately $97.1 billion annually due to the opening of the market for
switched services which will permit CLECs to offer a full range of local
telecommunications services including local dial tone, local calls, custom
calling features and intraLATA toll services for both business and residential
customers. In the markets where the Company's networks are currently operating
or under construction, the Company now believes it has an addressable market
opportunity of approximately $4.8 billion, substantially all of which is
currently provided by the incumbent LECs.
 
COMPANY STRATEGY
 
  The Company, through its networks, is a leading provider of integrated local
telecommunications services to small, medium and large businesses, government
and educational end users and IXCs in its existing markets. The Company
differentiates its service offerings by partnering with local cable television
operators and utility companies to develop networks that will provide customers
with greater market coverage, lower costs and superior service. The Company's
networks also leverage the IXCs' name recognition and reputation for quality
and reliability by becoming preferred suppliers for IXCs of local
telecommunications services in the Company's markets. The IXCs market their
long distance services in conjunction with the Company's local service
offerings to provide end users with a fully integrated telecommunications
service offering in all of the Company's operating markets. Principal elements
of the Company's strategy include:
 
 
                                       3
<PAGE>
 
  Develop a Rapid Entry/Low Cost Approach with Local Partners. The Company
works with a Local Partner in order to significantly reduce the cost and time
to construct a fiber optic network, enable the Company to rapidly begin
offering services and lower the overhead associated with operating and
maintaining the Company's networks. Advantages of building the Company's
networks with Local Partners include (i) sharing the cost of building the fiber
optic network with a cable television system or utility system which the
Company believes reduces the cost of aerial fiber construction by approximately
62%, (ii) reducing the time and cost of obtaining access to rights-of-way and
building entrances and (iii) enabling the Company to leverage the Local
Partners' experience and capabilities for maintaining fiber optic cables
thereby significantly reducing the ongoing costs of a fiber optic network.
Through the partnerships, the Company has financed its expansion at a lower
cost relative to its competitors by utilizing pro rata equity investments and
Local Partner financings of a significant portion of fiber construction. Local
Partners provide most of the funds for the fiber build in a network and lease
the fiber capacity back to the partnership under long-term agreements.
 
  Build Broad Network Coverage. The Company intends to build substantially
larger networks than the networks of the CLECs it competes with in its markets.
As of February 29, 1996, in all of the markets in which the Company and its
networks operate, management believes that the Company has the broadest network
coverage in terms of route miles of any of its CLEC competitors. The Company
believes that expanded network coverage will enable the Company to (i) provide
broader and more reliable coverage for network customers, (ii) carry a greater
amount of traffic on its own networks rather than on the networks of other
carriers thereby increasing the Company's revenues and profit margins, (iii)
increase the potential market available to the Company due to the greater
number of buildings, LEC-COs and customers that the Company's networks can
service, (iv) improve the value of the Company's networks to IXCs, cellular
providers and new telecommunications providers such as Personal Communications
Service ("PCS") operators that need wide backbone coverage, (v) offer services
in areas where there are fewer potential CLECs with facilities and (vi)
leverage the fixed cost structure of the Company's networks, particularly with
regard to network electronics such as switches.
 
  Expansion through Development of Network Clusters. The Company intends to
build on its extensive network size by adding markets near its existing
networks and targeting markets in close proximity when establishing new
networks. Management believes that there are significant operating and
marketing advantages to locating its networks in clusters. Clustering enables
the Company to (i) take advantage of economies of scale in management,
construction, network operations and sales and marketing, (ii) optimize the
networks' switching capacity by utilizing remote switch capacity in nearby
cities, (iii) offer services to lower density traffic areas in which the
Company's networks are less likely to face strong competition from incumbent
LECs and other CLECs and (iv) increase the networks' ability to offer highly
reliable, end-to-end connectivity on a regional basis. The Company also
believes that creating regional networks will enable the Company to gain a
greater share of high margin long distance transport traffic.
 
  Develop Strategic Relationships with IXCs. The Company, through its networks,
provides customers with an integrated, one-stop shopping approach to their
telecommunications needs through its strategic relationships with IXCs such as
AT&T, MCI, Sprint, WorldCom and others. The goal of these relationships is for
the Company's networks to offer their local services in conjunction with the
long distance services of these IXCs. Management believes that working in
partnership with IXCs instead of as a competitor will be attractive to IXCs and
enable the Company to (i) utilize extensive market information from the IXCs
regarding traffic patterns and building requirements to more optimally
construct and extend its networks, (ii) work closely with IXC account teams to
provide an integrated service approach to end users, (iii) increase market
penetration by capitalizing on the IXCs' name recognition and (iv) lower sales
and marketing costs by utilizing the extensive marketing resources and
salesforce of the IXCs to market the networks' products and services. In
pursuing this strategy, the Company has entered into a national service
agreement (the "National Service Agreement") with a major IXC pursuant to which
the Company's networks will be the major IXC's preferred supplier of dedicated
special access and switched access transport services.

  Expand Enhanced Service Offerings. Three of the Company's networks operate in
partnership with !NTERPRISE, a leading, nationwide network integrator that
designs, develops and deploys state-of-the-art data networks (including both
network services and equipment) to support and enhance the information systems
with which the networks' customers operate their businesses. Pursuant to the
partnership agreements, !NTERPRISE co-markets enhanced services, including
frame relay, ATM data transport, business video conferencing, private line data
interconnect service and LAN connection and monitoring services to the
networks' customers in the networks' respective markets. The Company believes
that the partnerships with !NTERPRISE provide the opportunity to offer network
customers a full complement of enhanced services more rapidly and without the
Company incurring the cost and overhead of establishing its own nationwide
enhanced services marketing, sales and installation effort. The Operating
Companies intend to enter into additional agreements with !NTERPRISE and other
service integrators in the future.
 
COMPANY AND PARTNERSHIP OWNERSHIP
 
  The Company is an 89% owned subsidiary of Adelphia, the seventh largest cable
television company in the United States which as of March 31, 1996 owned or
managed cable television systems that served approximately 1.65 million
subscribers in 15 states. The balance of the Company is owned by senior
management which has extensive experience in the telecommunications field. The
Company manages and operates networks in 13 markets. The Company owns its 13
operating networks through (i) partnerships with eight Local Partners (the
"Operating Partnerships") and (ii) two wholly-owned subsidiaries of the Company
and one corporation in which it is a minority shareholder ("Operating
Corporations") (collectively the Operating Partnerships and the Operating
Corporations are referred to herein as the "Operating Companies"). The Company
is responsible for the network design, construction, management and operation
of the Operating Companies, for which it receives management fees. Prior to May
16, 1996, the Company also had an investment in a partnership operating in
southern Florida (the "South Florida Partnership") in which it had no
management responsibility.
 
  The following is an overview of the Company's network structure as of June
15, 1996, except as noted below for the South Florida Partnership.

    responsibility with regard to such partnership. On May 16, 1996, the
    Company sold its investment in such partnership. See "Recent Developments."
 
RECENT DEVELOPMENTS
 
  Sale of Partnership Interest in the South Florida Partnership. On May 16,
1996, the Company completed the sale of its 15.7% partnership interest in TCG
South Florida to Teleport Communications Group Inc. for an aggregate sales
price of approximately $11.6 million resulting in a pre-tax gain of
approximately $8.4 million. Amounts related to the South Florida Partnership
included in the Company's investments and equity in net loss of joint ventures
as of and for the nine months ended December 31, 1995 were approximately $2.9
million and ($0.6) million, respectively. As part of the transaction, the
Company was released from its covenant not to compete with respect to the South
Florida market. The Company plans to use the proceeds from the sale to continue
to expand and develop its existing markets, complete new networks under
construction and enter additional markets.
 
  National Service Agreement with Major IXC. The Company has entered into the
National Service Agreement with a major IXC pursuant to which the Company's
networks will be the IXC's preferred supplier of dedicated special access and
switched access transport services. The National Service Agreement requires the
Company to provide such services to the IXC at a discount from the tariffed or
published incumbent LEC rates. The National Service Agreement is in effect in
all of the Company's markets. The Company believes that only four other CLECs
have comparable National Service Agreements and have passed such major IXC's
network validation tests and operational readiness testing.
 
                                       6

  Other Changes in Partnership Interests. The Company recently has entered into
an agreement or letter of intent pursuant to which the Company's ownership
interests in certain of the Operating Partnerships have recently increased or
are expected to increase in three markets. These transactions are consistent
with the Company's goal to own at least a 50% interest in its Operating
Partnerships in the future, and where appropriate the Company may consider
similar transactions from time to time in its other markets. Assuming the
successful completion of all of the transactions contemplated below, Hyperion
would own at least 50% of ten of its 17 then existing markets and markets under
construction.
 
  Pursuant to a binding letter of intent with TKR, dated as of January 29,
1996, and a subsequent amendment to the related partnership agreement dated May
8, 1996, the Company has agreed to make additional capital contributions to its
Louisville, Kentucky Operating Partnership (which will also operate the network
under construction in Lexington, Kentucky) and has increased its partnership
ownership interest to 50%. Under a nonbinding letter of intent with InterMedia,
dated as of February 12, 1996, the Company intends to increase its partnership
ownership interest in the Nashville, Tennessee Operating Partnership to at
least 51% and as much as 95% by purchasing the Local Partner's interests, at
the option of such partner.
 
  The consummation of the InterMedia transaction is subject to the negotiation
and execution of definitive, binding agreements and to other terms and
conditions. No assurances can be given as to whether or when, or the terms upon
which, any such transaction will be consummated.

                              not apply to the New Notes. See "Description
                              of Senior Notes."

                              consummation of the Exchange Offer, holders
                              of Old Notes that were not prohibited from

                              restrictions on transfer contained in the

  CONSEQUENCES OF EXCHANGING OR FAILURE TO EXCHANGE OLD NOTES PURSUANT TO THE
                                 EXCHANGE OFFER
 
  Generally, holders of Old Notes (other than any holder who is an "affiliate"
of the Company within the meaning of Rule 405 under the Securities Act) who
exchange their Old Notes for New Notes pursuant to the Exchange Offer may offer
their New Notes for resale, resell their New Notes, and otherwise transfer
their New Notes without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided such New Notes are acquired
in the ordinary course of the holder's business, such holders have no
arrangement with any person to participate in a distribution of such New Notes
and neither the holder nor any other person is engaging in or intends to engage
in a distribution of the New Notes. Each broker-dealer that receives New Notes
for its own account in exchange for Old Notes must acknowledge that it will
deliver a prospectus in connection with any resale of its New Notes. See "Plan
of Distribution." To comply with the securities laws of certain jurisdictions,
it may be necessary to qualify for sale or register the New Notes prior to
offering or selling such New Notes. The Company is required, under the
Registration Rights Agreement, to register the New Notes in any jurisdiction
requested by the holders, subject to certain limitations. Upon consummation of
the Exchange Offer, holders that were not prohibited from participating in the
Exchange Offer and did not tender their Old Notes will not have any
registration rights under the Registration Rights Agreement with respect to
such nontendered Old Notes, and accordingly, such Old Notes will continue to be
subject to the restrictions on transfer contained in the legend thereon. In
general, Old Notes may not be offered or sold, unless registered under the
Securities Act and applicable state securities laws. See "The Exchange Offer--
Consequences of Failure to Exchange."

                              Notes"). The terms of the New Notes and the
                              Old Notes are substantially identical in all
                              material respects, except for certain
                              transfer restrictions, registration rights
                              and Liquidated Damages for Registration
                              Defaults relating to the Old Notes which will
                              not apply to the New Notes. See "Description
                              of Senior Notes."

                              Senior Notes then outstanding at a redemption
                              price of 113.0% of the Accreted Value thereof
                              with the proceeds of (i) an Initial Public
                              Offering of common stock of the Company or
                              (ii) a sale of the Capital Stock (other than

                              however, that at least 75% of the aggregate
                              principal amount at maturity of the Senior

                              redemption and provided, further, that such
                              redemption shall occur within 90 days of the
                              date of the closing of such Initial Public

                              Investor, as the case may be.
 
Change of Control...........  In the event of a Change of Control, the
                              holders of the Senior Notes will have the
                              right to require the Company to purchase
                              their Senior Notes at a price equal to 101%
                              of the Accreted Value thereof or in the case
                              of any such purchase on or after April 15,
                              2001, at 101% of the aggregate principal
                              amount thereof, plus accrued and unpaid
                              interest, if any, to the date of purchase.
                              There can be no assurance that the Company
                              will have the financial resources necessary
                              to repurchase the Senior Notes upon a Change
                              of Control. See "Description of the Senior
                              Notes--Offer to Purchase upon Change of
                              Control."
 
Ranking.....................  The Senior Notes are general unsecured
                              obligations of the Company. The Senior Notes
                              rank pari passu in right of payment with all
                              existing and future senior Indebtedness of
                              the Company and senior in right of payment to
                              all future subordinated Indebtedness of the
                              Company. In addition, holders of indebtedness
                              and other liabilities of the Company's
                              Subsidiaries and Joint Ventures will have
                              claims that are effectively senior to the
                              Senior Notes. As of December 31, 1995, the
                              aggregate principal amount outstanding of
                              such senior Indebtedness (excluding trade
                              payables and other accrued liabilities) of
                              the Subsidiaries and Joint Ventures would
                              have been $22.7 million, substantially all of
                              which were Capital Lease Obligations.
 
Covenants...................  The indenture with respect to the Senior
                              Notes (the "Indenture") contains certain
                              covenants that, among other things, limit the
                              ability

                              a price equal to 100% of the Accreted Value
                              thereof or, in the case of any such purchase
                              on or after April 15, 2001, at 100% of the

(a) For purposes of calculating the ratio of earnings to fixed charges: (i)
    earnings consist of loss before income taxes, plus fixed charges excluding
    capitalized interest plus amortization of deferred financing costs and (ii)
    fixed charges consist of interest expensed and capitalized. For the fiscal
    years ended March 31, 1992, 1993, 1994 and 1995, the Company's earnings
    were insufficient to cover fixed charges by $213, $1,075, $4,822 and
    $7,721, respectively. For the nine months ended December 1994 and 1995, the
    Company's earnings were insufficient to cover fixed charges by $5,715 and
    $9,921, respectively.
(b) Pro forma interest expense assumes (i) repayment of $25.0 million of the
    Adelphia Note (as defined) at an interest rate of 11.28%, (ii) gross
    proceeds attributable to the issuance of the Senior Notes of $163.7
    million, (iii) issuance of the Senior Notes at an interest rate of 13.0%
    and (iv) original issue discount attributable to the Warrants.

(c) On a pro forma basis, for the nine months ended December 31, 1995, the
    Company's earnings would have been insufficient to cover fixed charges by
    $25,845.
(d) EBITDA consists of net income (loss) before equity in net loss of joint
    ventures, interest, income taxes, depreciation and amortization for the
    periods presented. It is a measure commonly used in the telecommunications
    industry and is presented to assist in understanding the Company's
    operating results. However, it is not intended to represent cash flow or
    results of operations in accordance with generally accepted accounting
    principles. See the Company's Consolidated Financial Statements and Notes
    thereto appearing elsewhere in this Prospectus.
(e) For the fiscal years ended March 31, 1992, 1993, 1994 and 1995, the
    Company's capital expenditures (including capital expenditures relating to
    its wholly-owned Operating Companies) were $60, $1,950, $3,097 and $2,850,
    respectively, and the Company's investments in its less than wholly-owned
    Operating Companies and the South Florida Partnership were $0, $1,941,
    $5,510 and $7,526, respectively, for the same periods. For the nine months
    ended December 31, 1994 and 1995, the Company's capital expenditures
    (including capital expenditures relating to its wholly-owned Operating
    Companies) were $1,191 and $4,473, respectively and the Company's
    investments in its less than wholly-owned Operating Companies and the South
    Florida Partnership were $6,357 and $9,097, respectively, for the same
    periods. See the Company's Consolidated Financial Statements and Notes
    thereto appearing elsewhere in this Prospectus.
(f) Gives effect to (i) the consummation of the sale on April 15, 1996 of
    329,000 Units ("Units") (the "Offering") consisting of $329,000,000
    aggregate principal amount at maturity of Senior Notes and Warrants to
    purchase an aggregate of 613,427 shares of Common Stock of the Company, and
    the allocation of approximately $163.7 million to the Senior Notes and
    approximately $11.6 million to the Warrants and (ii) the application of the
    estimated net proceeds from such sale, including the repayment of certain
    indebtedness and loans to certain stockholders.
(g) Network Data is derived from the Company's records and presents information
    for the Operating Companies, but does not include information for the South
    Florida Partnership.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business in connection with the Exchange Offer.
 
  Consequences of Failure to Exchange. Upon consummation of the Exchange
Offer, holders of Old Notes that were not prohibited from participating in the
Exchange Offer and did not tender their Old Notes will not have any
registration rights under the Registration Rights Agreement with respect to
such nontendered Old Notes and, accordingly, such Old Notes will continue to
be subject to the restrictions on transfer contained in the legend thereon. In
general, the Old Notes may not be offered or sold, unless registered under the
Securities Act and applicable state securities laws, except pursuant to an
exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. The Company does not intend to register the
Old Notes under the Securities Act. Based on interpretations by the staff of
the Commission with respect to similar transactions, the Company believes that
the New Notes issued pursuant to the Exchange Offer in exchange for Old Notes
may be offered for resale, resold and otherwise transferred by any holder of
such New Notes (other than any such holder which is an "affiliate" of Hyperion
within the meaning of Rule 405 under the Securities Act) without compliance
with the registration and prospectus delivery provisions of the Securities
Act, provided that such New Notes are acquired in the ordinary course of such
holder's business, such holder has no arrangement or understanding with any
person to participate in the distribution of such New Notes and neither the
holder nor any other person is engaging in or intends to engage in a
distribution of the New Notes. Each broker-dealer that receives New Notes for
its own account in exchange for Old Notes must acknowledge that it will
deliver a prospectus in connection with any resale of its New Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of the New Notes received in exchange for
the Old Notes acquired by the broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that it will
make this Prospectus available to any broker-dealer for use in connection with
any such resale for a period of 365 days after the Exchange Date or, if
earlier, until all participating broker-dealers have so resold. See "Plan of
Distribution." The New Notes may not be offered or sold unless they have been
registered or qualified for sale under applicable state securities laws or an
exemption from registration or qualification is available and is complied
with. The Company is required, under the Registration Rights Agreement, to
register the New Notes in any jurisdiction requested by the holders, subject
to certain limitations.
 
  Absence of a Public Market. Prior to this Exchange Offer, there has been no
public market for the Old Notes. If a market for the New Notes should develop,
the New Notes could trade at a discount from their principal amount. The
Company does not currently intend to list the New Notes on any securities
exchange or to seek approval for quotation through any automated quotation
system. There can be no assurance that an active public market for the New
Notes will develop.
 
  Negative Cash Flow and Operating Losses; Limited History of Operations. The
Company has experienced significant losses since its inception, with operating
losses of approximately ($2.1) million, ($2.6) million and ($2.6) million for
the fiscal years ended March 31, 1994 and 1995 and the nine months ended
December 31, 1995, respectively. The Company expects to continue to incur
substantial operating losses in the foreseeable future as it pursues its plans
to expand its networks, service offerings and customer base. There can be no
assurance that such losses will not continue indefinitely. The Company
currently accounts for its ownership interests in the Operating Companies in
which it does not have majority ownership interest using the equity method
and, therefore, the Company's consolidated financial statements include only
the Company's pro rata share of the Operating Companies' and the South Florida
Partnership's net losses as equity in net losses of joint ventures.
 
  The Company was formed in October 1991 and ten of its 13 networks have been
in operation for less than 24 months. Prospective investors therefore have
limited historical financial information about the Company upon
 
                                      14
<PAGE>
 
which to base an evaluation of the Company's performance. The development of
the Company's businesses and the installation and expansion of its networks
require significant expenditures, a substantial portion of which are made
before any revenues may be realized. Certain of the expenditures, including
marketing, sales and general and administrative costs, are expensed as
incurred, while certain other expenditures, including network design and
construction, negotiation of rights-of-way and costs to obtain legal and
regulatory approval, are deferred until the applicable network is operational.
The Company will continue to incur significant expenditures in connection with
the construction, acquisition, development and expansion of the Company's and
Operating Companies' networks, services and customer base.
 
  In light of the Company's limited operating history, its history of
significant operating losses and its expectation that it will continue to
incur significant expenses and operating losses for the foreseeable future,
there can be no assurance that the Company will be able to implement its
growth strategy, achieve or sustain profitability or generate sufficient cash
flow to service the Senior Notes. If the Company is unable to generate
positive cash flow, holders of the Senior Notes would be adversely affected.
 
  Substantial Leverage. As of December 31, 1995, after giving pro forma effect
to the Offering, the Company's total amount of debt outstanding would have
been $188.7 million and the Company would have had a stockholders' deficiency
of $15.4 million. In addition, in each year since its inception, the Company's
earnings have been inadequate to cover its fixed charges by a substantial
margin. Commencing on October 15, 2001, semi-annual cash interest payments of
$21.4 million will be due on the Senior Notes, which substantially exceeds the
Company's gross revenues of approximately $2.5 million for the nine months
ended December 31, 1995.
 
  Because the Company currently has a consolidated cash flow deficit, its
ability to make cash interest payments on the Senior Notes commencing on
October 15, 2001 and to repay its obligations on the Senior Notes at maturity
will be dependent on developing one or more sources of cash flow prior to the
date on which cash interest payment obligations begin on the Senior Notes. To
accomplish this the Company may seek to (i) refinance all or a portion of the
Senior Notes, (ii) sell all or a portion of its interests in one or more of
the Operating Companies, (iii) negotiate with its current Local Partners to
permit any excess cash generated by its Operating Companies to be distributed
to partners rather than invested in the businesses of such Operating Companies
and/or (iv) invest in companies that will make substantial cash distributions
on or before the maturity of the Senior Notes. There can be no assurance that
(i) there will be a market for the debt or equity securities of the Company in
the future, (ii) the Company will be able to sell assets in a timely manner or
on commercially reasonable terms or in an amount that will be sufficient to
make cash interest payments and repay the Senior Notes when due, (iii) the
Company will be able to persuade its Local Partners that cash generated by the
operations of the Operating Companies should be distributed to partners or
shareholders or (iv) the Company will be able to locate and invest in
companies that will be mature enough to make substantial cash contributions to
the Company prior to the maturity date of the Senior Notes. The inability of
the Company to develop any of the sources of liquidity described above could
adversely affect the holders of the Senior Notes.
 
  In addition, the Company's ability to sell or transfer its or its
subsidiaries' ownership interest in the Operating Companies is subject to
limitations contained in the various subscription and partnership agreements,
including, in certain cases, complete prohibitions on sales or transfers for a
period of three to five years after formation and/or rights of first refusal.
Furthermore, none of the ownership interests in the Operating Companies are,
or are expected to be, publicly traded securities. As a result, the Company's
ability to liquidate any or all of the ownership interests in the Operating
Companies will be substantially limited, and there can be no guarantee that
the Company will be able to do so in a timely manner in the event of an
acceleration of the Senior Notes prior to their maturity or in order to
satisfy its obligations in respect of such securities in the event of a Change
of Control or to otherwise make payments on the Senior Notes prior to or at
their maturity.
 
  Holding Company Structure; Inability to Access Cash Flow. The Company is a
holding company with substantially all of its operations conducted through the
Operating Companies and the Company expects that it could develop new networks
and operations in the future through Joint Ventures in which the Company will
 
                                      15
<PAGE>
 
own less than 50% of the equity interests. Accordingly, the Company's cash
flow and, consequently, its ability to service its debt, including the Senior
Notes, is dependent on its pro rata share of the cash flow of the Operating
Companies and the payment of funds by those Operating Companies in the form of
management fees, loans, dividends, distributions or otherwise. The Operating
Companies are separate and distinct legal entities and have no obligation,
contingent or otherwise, to pay any amounts due pursuant to the Senior Notes
or to make any funds available therefor, whether in the form of loans,
dividends, distributions or otherwise. Furthermore, the Company may be unable
to access the cash flow of certain of the Operating Companies because it holds
a 50% or less ownership interest in certain of such entities and, therefore,
does not have the requisite control to cause such entities to make
distributions or pay dividends (as applicable) to the partners or equity
holders (as applicable). In addition, such entities will be permitted to incur
indebtedness that may severely restrict or prohibit the making of
distributions, the payment of dividends (as applicable) or the making of
loans. The inability of the Company to receive cash from the Operating
Companies would adversely affect the holders of the Senior Notes.
 
  Ranking. The Senior Notes are obligations of the Company exclusively and are
not secured by any of the assets of the Company, its subsidiaries or the
Operating Companies. Accordingly, holders of secured indebtedness of the
Company will have claims that are prior to the claims of the holders of the
Senior Notes to the extent of the assets securing such other indebtedness. In
addition, holders of indebtedness and other liabilities of the Company's
subsidiaries and the Joint Ventures will have claims that are effectively
senior to the Senior Notes. As of December 31, 1995, the aggregate principal
amount of such senior Indebtedness incurred by the Company's subsidiaries and
Joint Ventures (excluding trade payables and other accrued liabilities) was
approximately $22.7 million, substantially all of which were Capital Lease
Obligations. The Indenture permits certain indebtedness of the Company, its
Subsidiaries and the Joint Ventures to be secured. See "Description of the
Senior Notes."
 
  Risks Associated with Joint Ventures. Most of the Operating Companies' Local
Partner Agreements (as defined) contain mandatory buy/sell provisions that,
after a certain number of years, can be initiated by either partner and result
in one partner purchasing all of the other partner's interests. Accordingly,
there can be no assurance that the Company and its subsidiaries will continue
to be in partnership with their current Local Partner, or any other partner,
in each of their respective markets, or that the Company or its subsidiaries
will have sufficient funds to purchase the partnership interest of such other
partner. In addition, if a partner triggers such buy/sell provisions and the
Company is unable to purchase the initiating partner's interests, the Company
will be forced to sell its interests to the partner, thereby terminating the
partnership, which could result in a material adverse effect on the future
cash flow of the Company.
 
  The bankruptcy or insolvency of a Local Partner or an Operating Company
could result in the termination of the respective Local Partner Agreement and
the related Fiber Lease Agreement (as defined). The effect of such
terminations could be materially adverse to the Company and the respective
Operating Company. Similarly, all of the Management Agreements (as defined),
two of the Local Partner Agreements and five of the Fiber Lease Agreements can
be terminated by the respective Local Partner at various times during the next
seven years. While the Company believes such agreements will be renewed, there
can be no assurance that the Local Partner will not seek to terminate the
agreements. See "Business--Operating Agreements." Accordingly, the failure to
renew such agreements could materially adversely affect the Company and the
respective Operating Companies. In addition, the failure of a Local Partner to
make required capital contributions could have a material adverse effect on
the Company and the respective Operating Company.
 
  The Indenture does not restrict Operating Companies in which the Company
owns a less than 45% interest with respect to the amount of indebtedness they
can incur. Accordingly, the Company's ability to access the cash flow and
assets of such Operating Companies may be severely limited. While none of the
Operating Companies currently have a substantial amount of indebtedness, there
can be no assurance that such Operating Companies will not incur substantial
indebtedness in the future. See "Description of the Senior Notes-- Incurrence
of Indebtedness and Issuance of Preferred Stock."

  Significant Future Capital Requirements. Expansion of the Company's existing
networks and services and the development of new networks and services require
significant capital expenditures. The Company's
operations have required and will continue to require substantial capital
investment for (i) the installation of electronics for switched services in
the Company's networks, (ii) the expansion and improvement of the Company's
NOCC and existing networks and (iii) the design, construction and development
of additional networks. The Company plans to make substantial capital
investments and investments in Operating Companies in connection with the
deployment of switches in all of its operating markets by the end of 1996, the
expansion of existing markets and the construction and development of new
markets. Expansion of the Company's networks will include the geographic
expansion of the Company's existing clusters and the development of new
markets. The Company expects to build networks in approximately ten additional
markets by the end of 1997. The Company estimates that it will require
approximately $110 million to $115 million to fund anticipated capital
expenditures, working capital requirements and operating losses of the Company
and to make investments in existing and new Operating Companies and to enter
certain additional markets during calendar 1996 and 1997. In order to achieve
its goal of entering ten new markets by the end of 1997, however, the Company
expects to be required to seek additional capital. The Company expects to fund
additional capital requirements through existing resources, secured credit
facilities at the Company and Operating Company levels, internally generated
funds, equity invested by Local Partners in Operating Companies, additional
Operating Companies and additional debt or equity financings, as appropriate.
 
  The Company may also be required to raise capital (i) to fund the planned
purchase of certain partnership interests in the Louisville Operating
Partnership and the Nashville Operating Partnership and (ii) in order to
purchase the partnership interests of a Local Partner seeking to exercise its
right to sell its partnership interest. See "--Risks Associated with Joint
Ventures," "Business--Recent Developments" and "Business--Local Partner
Agreements." There can be no assurance, however, that the Company will be
successful in generating sufficient cash flow or in raising sufficient debt or
equity capital on terms that it will consider acceptable, or at all. The lack
of available additional capital would have a significant negative effect on
the Company's growth and its ability to effectively compete in the
telecommunications industry and would adversely impact the holders of the
Senior Notes. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."
 
  The expectations of required future capital expenditures are based on the
Company's current estimates. There can be no assurance that actual
expenditures will not significantly exceed current estimates.
 
  Expansion Risk. The Company is experiencing a period of rapid expansion
which the Company believes will increase following the Offering. The operating
complexity of the Company, as well as the level of responsibility for
management personnel, has increased as a result of this expansion. The
Company's ability to manage such growth effectively will require it to
continue to expand 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 and the holders of the Senior Notes.
 
  Competition. In each of the markets served by the Company's networks, the
services offered by the Company compete principally with the services offered
by the incumbent LEC serving that area. Incumbent LECs have long-standing
relationships with their customers, have the potential to subsidize
competitive services from monopoly service revenues, and benefit from
favorable state and federal regulations. In light of the passage of the
Telecommunications Act, federal and state regulatory initiatives will provide
increased business opportunities to CLECs such as the Company, but regulators
are likely to provide incumbent LECs with increased pricing flexibility for
their services as competition increases. If incumbent LECs are allowed by
regulators to lower their rates substantially, engage in excessive volume and
term discount pricing practices for their customers, or charge CLECs excessive
fees for interconnection to the incumbent LECs' networks, the net income and
cash flow of CLECs, including the Operating Companies, could be materially
adversely affected.
 
  The Telecommunications Act also establishes procedures under which the
Regional Bell Operating Companies ("RBOCs") can obtain authority to provide
long distance services if they comply with certain
 
                                      17
<PAGE>
 
interconnection requirements. There has been significant merger activity among
the RBOCs in anticipation of entry into the long distance market. If RBOCs are
permitted to provide such services, they will ultimately be in
a position to offer single source service. This could result in decreased
market share for the major IXCs, which are the Company networks' major
customers. Such a result could have an adverse effect on the Company.
 
  The Company also faces, and will continue to face, competition from other
current and potential market entrants, including other CLECs, AT&T, MCI,
Sprint and other IXCs, cable television companies, electric utilities,
microwave carriers, wireless telecommunications providers and private networks
built by large end users. A number of markets served by the Company already
are served by another CLEC or other CLECs. In addition, all three major IXCs
are expected to enter the market for local telecommunications services. MCI
has announced that it will invest more than $2.0 billion in fiber optic rings
and local switching equipment in major metropolitan markets throughout the
United States and AT&T has filed applications with the FCC for authority to
provide local telecommunications services in all 50 states. Although the
Company has good relationships with the IXCs, there are no assurances that any
of these IXCs will not build their own facilities or resell the services of
other carriers rather than use the Company's services when entering the market
for local exchange services.
 
  The Company also competes with equipment vendors and installers, and
telecommunications management companies with respect to certain portions of
its business.
 
  Many of the Company's current and potential competitors, particularly
incumbent LECs, have financial, personnel and other resources substantially
greater than those of the Company, as well as other competitive advantages
over the Company. See "Competition" for more detailed information on the
competitive environment faced by the Company.
 
  Dependence on Business from IXCs. For the nine months ended December 31,
1995, approximately 78% of the Operating Companies' combined revenues were
attributable to access services provided to IXCs, one of which accounted for
approximately 55% of such combined IXCs' revenues. The loss of access revenues
from IXCs in general or the loss of such single IXC as a customer could have a
material adverse effect on the Company's business. See "Business--Company
Strategy--Customer Strategy."
 
  The Company's growth strategy assumes increased revenues from IXCs and end
users following the deployment of switches on the Company's networks and the
provision of switched access origination and termination services. In
addition, the Company competes in its markets with other CLECs for IXC
business. Accordingly, 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, either of which could have
a material adverse effect on the Company.
 
  Furthermore, the Telecommunications Act establishes procedures under which
RBOCs can obtain authority to compete with the IXCs in the long distance
market. Due to the Operating Companies' dependence on business from IXCs, any
loss of market share by the IXCs could have a material adverse effect on the
Company.
 
  Regulation and Risks of the Telecommunications Act. 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 by the FCC, nor is
it currently required to obtain FCC authorization for the installation,
acquisition or operation of its network facilities. However, the FCC has
determined that nondominant carriers, such as the Company and the Operating
Companies, are required to file interstate tariffs on an ongoing basis. The
Telecommunications Act also requires the FCC to establish a subsidy mechanism
for universal telephone service to which the Company will be required to
contribute. The Operating Companies that provide intrastate services are also
generally subject to certification and tariff filing requirements by state
regulators and may also be subject to reporting, customer service and
universal service requirements. Challenges to these tariffs by third parties
could cause the Company to incur substantial legal and administrative
expenses. In addition, under the Telecommunications Act, provision of switched
services by the Company could be subject to a far greater degree
 
                                      18
<PAGE>
 
of regulation than previously experienced by the Company with regard to its
nonswitched services. See "Regulation--Telecommunications Act of 1996."
 
  Although the Telecommunications Act eliminates legal barriers to entry, 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 particular, the Company's belief that the entire $97
billion local exchange market may ultimately be open to CLEC competition
depends upon favorable interpretation of the Telecommunications Act, and the
ability of the Company and the Operating Companies to compete in these new
market segments may be adversely affected if incumbent LECs are granted
greater pricing flexibility and other regulatory relief that enables them to
impose costs on potential competitors or otherwise restrict the Company's
ability to serve its customers and attract new customers. In addition, the
Telecommunications Act removes entry barriers for all companies and could
increase substantially the number of competitors offering comparable services
in the Company's markets. See "Regulation--Overview" for more detailed
information on the regulatory environment in which the Company and the
Operating Companies operate.
 
  Need to Obtain and Maintain Permits and Rights-of-Way. There can be no
assurance that the Company or the Operating Companies, through Local Partners,
Adelphia or their own efforts, will be able to maintain existing permits and
rights-of-way or to obtain and maintain the other permits and rights-of-way
needed to develop and operate existing and future networks. In addition, the
Company and the Operating Companies may require pole attachment agreements
with electric utilities to operate existing and future networks, and there can
be no assurance that such agreements will be obtained or will be obtainable on
reasonable terms. Failure to obtain or maintain such permits, rights-of-way
and agreements could have a material adverse effect on the Company's ability
to operate and expand its networks. See "Business--Operating Agreements--Fiber
Lease Agreements."
 
  Control by Principal Shareholder. Adelphia owns approximately 89% of the
outstanding capital stock of the Company, with the remaining 11% owned by
certain of the Company's senior management (the "Management Shareholders").
Accordingly, Adelphia is able to control the vote on corporate matters
requiring shareholder approval, including, but not limited to, electing
directors, amending the Company's certificate of incorporation and approving
mergers or sales of substantially all of the Company's assets. In addition,
pursuant to a shareholders agreement, as amended, between the Company,
Adelphia and the Management Shareholders, Adelphia has the power to control
certain corporate transactions of the Company, including its ability to enter
into joint ventures and other business relationships, and Adelphia has the
right, under certain circumstances, to purchase the interests of the
Management Shareholders. In addition, Adelphia has agreed to vote its shares
of the Common Stock of the Company to elect the Management Shareholders to the
Company's Board of Directors. There can be no assurance that the interests of
Adelphia will not conflict with the interest of the holders of the Senior
Notes. See "Certain Relationships and Transactions."
 
  Rapid Technological Changes. The telecommunications industry is subject to
rapid and significant changes in technology. While the Company believes that
for the foreseeable future these changes will neither materially affect the
continued use of fiber optic telecommunications networks nor materially hinder
the Company's ability to acquire necessary technologies, the effect of
technological changes on the businesses of the Company cannot be predicted.
Thus, there can be no assurance that technological developments will not have
a material adverse effect on the Company.
 
  Dependence on Key Personnel. The success of the Company and its growth
strategy depends in large part on the Company's ability to attract and retain
key management, marketing and operations personnel. Currently, the Company's
businesses are managed by a small number of management and operating personnel
with certain other services, including financial and certain accounting
services, provided by Adelphia. There can be no assurance that the Company
will attract and retain the qualified personnel needed to manage, operate and
further develop its business. In addition, the loss of the services of any one
or more members of the Company's senior management team could have a material
adverse effect on the Company.

  Original Issue Discount; Possible Unfavorable Tax and Other Legal
Consequences for Holders of Senior Notes and the Company. The Senior Notes
were issued at a substantial discount from the stated principal amount
thereof. Consequently, holders of the Senior Notes should be aware that,
although interest will not accrue
on the Senior Notes prior to April 15, 2001, and there will be no periodic
payments of cash interest on the Senior Notes prior to October 15, 2001,
original issue discount (i.e., the difference between the stated redemption
price at maturity and the issue price of the Senior Notes) will accrue from
the issue date of the Senior Notes and will be includible as interest income
periodically (including for periods ending prior to April 15, 2001) in a
holder's gross income for U.S. federal income tax purposes in advance of
receipt of the cash payments to which the income is attributable. Similar
results may apply under state and other tax laws.
 
  If a bankruptcy case is commenced by or against the Company under the U.S.
Bankruptcy Code, the claim of a holder of Senior Notes with respect to the
principal amount thereof may be limited to an amount equal to the sum of (i)
the initial offering price and (ii) that portion of the original issue
discount that is not deemed to constitute "unmatured interest" for purposes of
the U.S. Bankruptcy Code. Any original issue discount that was not amortized
as of any such bankruptcy filing would constitute "unmatured interest."
 
  See "Certain Federal Income Tax Consequences."
 
                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  On April 15, 1996, Hyperion issued $329,000,000 aggregate principal amount
at maturity of Old Notes to Bear, Stearns & Co. Inc., Chase Securities Inc.
and NationsBanc Capital Markets, Inc., the Initial Purchasers. The issuance
was not registered under the Securities Act in reliance upon the exemption
under Rule 144A and Section 4(2) of the Securities Act. In connection with the
issuance and sale of the Old Notes, Hyperion entered into a Registration
Rights Agreement with the Initial Purchasers dated as of April 15, 1996 (the
"Registration Rights Agreement"), which requires Hyperion to cause the Old
Notes to be registered under the Securities Act or to file with the Commission
a registration statement under the Securities Act with respect to an issue of
new notes of Hyperion identical in all material respects to the Old Notes, and
use its best efforts to cause such registration statement to become effective
under the Securities Act and, upon the effectiveness of that registration
statement, to offer to the holders of the Old Notes the opportunity to
exchange their Old Notes for a like principal amount of New Notes, which will
be issued without a restrictive legend and may be reoffered and resold by the
holder without restrictions or limitations under the Securities Act. A copy of
the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part. The Exchange Offer
is being made pursuant to the Registration Rights Agreement to satisfy
Hyperion's obligations thereunder.
 
  Based on no-action letters issued by the staff of the Commission to third
parties, Hyperion believes that the New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any holder of such New Notes (other than any such
holder which is an "affiliate" of Hyperion within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business, such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes and neither the holder nor any other person
is engaging in or intends to engage in a distribution of the New Notes. Any
holder who tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Notes cannot rely on such interpretation by the staff
of the Commission and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction. Each broker dealer that receives New Notes for its own account in
exchange for Old Notes, where such Old Notes were acquired by such broker-
dealer as a result of market-making activities or other trading activities,
must acknowledge that it will deliver a prospectus in connection with any
resale of such New Notes. See "Plan of Distribution."
 
 
                                      20

TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal (which together constitute the
Exchange Offer), Hyperion will accept any and all Old Notes validly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the
Expiration Date. The Company will issue a principal amount of New Notes in
exchange for an equal principal amount of outstanding Old Notes tendered and
accepted in the Exchange Offer. Holders may tender some or all of their Old
Notes pursuant to the Exchange Offer. The date of acceptance for exchange of
the Old Notes for the New Notes (the "Exchange Date") will be the first
business day following the Expiration Date.
 
  The terms of the New Notes and the Old Notes are substantially identical in
all material respects, except for certain transfer restrictions, registration
rights and Liquidated Damages for Registration Defaults relating to the Old
Notes which will not apply to the New Notes. See "Description of Senior
Notes." The New Notes will evidence the same debt as the Old Notes. The New
Notes will be issued under and entitled to the benefits of the Indenture
pursuant to which the Old Notes were issued.
 
  As of the date of this Prospectus, $329,000,000 aggregate principal amount
at maturity of the Old Notes are outstanding. This Prospectus, together with
the Letter of Transmittal, is being sent to all registered holders.
 
  Holders of Old Notes do not have any appraisal or dissenters' rights under
the General Corporation Law of Delaware or the Indenture in connection with
the Exchange Offer. Hyperion intends to conduct the Exchange Offer in
accordance with the provisions of the Registration Rights Agreement and the
applicable requirements of the Exchange Act, and the rules and regulations of
the Commission thereunder. Old Notes which are not tendered and were not
prohibited from being tendered for exchange in the Exchange Offer will remain
outstanding and continue to accrue interest and to be subject to transfer
restrictions, but will not be entitled to any rights or benefits under the
Registration Rights Agreement.
 
  Upon satisfaction or waiver of all the conditions to the Exchange Offer, on
the Exchange Date Hyperion will accept all Old Notes properly tendered and not
withdrawn and will issue New Notes in exchange therefor. For purposes of the
Exchange Offer, Hyperion shall be deemed to have accepted properly tendered
Old Notes for exchange when, as and if Hyperion has given oral or written
notice thereof to the Exchange Agent. The Exchange Agent will act as agent for
the tendering holders for the purposes of receiving the New Notes from
Hyperion.
 
  In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of such Old Notes, a properly completed and duly
executed Letter of Transmittal and all other required documents; provided,
however, that Hyperion reserves the absolute right to waive any defects or
irregularities in the tender or conditions of the Exchange Offer. If any
tendered Old Notes are not accepted for any reason set forth in the terms and
conditions of the Exchange Offer or if Old Notes are submitted for a greater
principal amount than the holder desires to exchange, such unaccepted or
nonexchanged Old Notes or substitute Old Notes evidencing the unaccepted
portion, as appropriate, will be returned without expense to the tendering
holder thereof as promptly as practicable after the expiration or termination
of the Exchange Offer.
 
  Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes pursuant to the Exchange Offer. Hyperion will pay all charges and
expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See "Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date," shall mean 5:00 p.m., New York City time, on
       , 1996, unless Hyperion, in its sole discretion, extends the Exchange
Offer, in which case the term "Expiration Date" shall
 
                                      21
<PAGE>
 
mean the latest date and time to which the Exchange Offer is extended;
provided that the Exchange Offer shall not be extended beyond 30 business days
after the date of this Prospectus.
 
  In order to extend the Expiration Date, Hyperion will notify the Exchange
Agent of any extension by oral or written notice and will mail to the
registered holders an announcement thereof, prior to 9:00 a.m., New York City
time, on the next business day after the then Expiration Date.
 
  Hyperion reserves the right, in its sole discretion, (i) to delay accepting
any Old Notes, to extend the Exchange Offer or to terminate the Exchange Offer
if any of the conditions set forth below under "Conditions" shall not have
been satisfied, by giving oral or written notice of such delay, extension or
termination to the Exchange Agent or (ii) to amend the terms of the Exchange
Offer. Any such delay in acceptance, extension, termination or amendment will
be followed as promptly as practicable by oral or written notice thereof. If
the Exchange Offer is amended in a manner determined by Hyperion to constitute
a material change, Hyperion will promptly disclose such amendment in a manner
reasonably calculated to inform the holders of Old Notes of such amendment.
 
  Without limiting the manner in which Hyperion may choose to make a public
announcement of any delay, extension, amendment or termination of the Exchange
Offer, Hyperion shall have no obligation to publish, advertise, or otherwise
communicate any such public announcement, other than by making a timely
release to an appropriate news agency.
 
INTEREST ON THE NEW NOTES
 
  Cash interest will not accrue on the New Notes prior to April 15, 2001.
Thereafter, the New Notes will bear interest at the rate of 13% per annum,
payable semi-annually, in cash, on April 15 and October 15 of each year,
commencing October 15, 2001.
 
CONDITIONS
 
  Notwithstanding any other term of the Exchange Offer, Hyperion will not be
required to exchange any New Notes for any Old Notes, and may terminate or
amend the Exchange Offer before the acceptance of any Old Notes for exchange,
if:
 
  (a) any action or proceeding is instituted or threatened in any court or by
      or before any governmental agency with respect to the Exchange Offer
      which seeks to restrain or prohibit the Exchange Offer or, in
      Hyperion's judgment, would materially impair the ability of Hyperion to
      proceed with the Exchange Offer; or
 
  (b) any law, statute, rule or regulation is proposed, adopted or enacted,
      or any existing law, statute, rule, order or regulation is interpreted,
      by any government or governmental authority which, in Hyperion's
      judgment, would materially impair the ability of Hyperion to proceed
      with the Exchange Offer; or
 
  (c) the Exchange Offer or the consummation thereof would otherwise violate
      or be prohibited by applicable law.
 
  If Hyperion determines in its sole discretion that any of these conditions
is not satisfied, Hyperion may (i) refuse to accept any Old Notes and return
all tendered Old Notes to the tendering holders, (ii) extend the Exchange
Offer and retain all Old Notes tendered prior to the expiration of the
Exchange Offer, subject, however, to the rights of holders who tendered such
Old Notes to withdraw their tendered Old Notes, or (iii) waive such
unsatisfied conditions with respect to the Exchange Offer and accept all
properly tendered Old Notes which have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, Hyperion will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and Hyperion will extend the Exchange
Offer for a period of five to ten business days, depending upon the
significance of the waiver and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such five to ten
business day period.
 
                                      22
<PAGE>
 
  The foregoing conditions are for the sole benefit of Hyperion and may be
asserted by Hyperion regardless of the circumstances giving rise to any such
condition or may be waived by Hyperion in whole or in part at any time and
from time to time in its sole discretion. The failure by Hyperion at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any
such right, and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time. Any determination by Hyperion
concerning the events described above shall be final and binding on all
parties.
 
PROCEDURES FOR TENDERING
 
  The tender of Old Notes by a holder as set forth below and the acceptance
thereof by Hyperion will constitute an agreement between such holder and
Hyperion in accordance with the terms and subject to the conditions set forth
in this Prospectus and in the Letter of Transmittal.
 
  Only a holder of Old Notes may tender such Old Notes in the Exchange Offer.
To tender in the Exchange Offer, a holder must (i) complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, together with the Old
Notes (unless such tender is being effected pursuant to the procedure for
book-entry transfer described below) and any other required documents, to the
Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date,
or (ii) comply with the guaranteed delivery procedures described below.
Delivery of all documents must be made to the Exchange Agent at its address
set forth herein.
 
  THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO HYPERION. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES
OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. If such
beneficial owner wishes to tender on such owner's own behalf, such owner must,
prior to completing and executing the Letter of Transmittal and delivering of
such owner's Old Notes, either make appropriate arrangements to register
ownership of the Old Notes in such owner's name or obtain a properly completed
bond power from the registered holder. The transfer of registered ownership
may take considerable time.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by any Eligible Institution (as defined) unless the
Old Notes tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Payment Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter
of Transmittal or a notice of withdrawal, as the case may be, are required to
be guaranteed, such guarantee must be by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible
Institution").
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, such Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by such registered
holder as such registered holder's name appears on such Old Notes, with the
signature thereon guaranteed by an Eligible Institution. If the Letter of
Transmittal or any Old Notes or bond powers are signed by
 
                                      23
<PAGE>
 
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by Hyperion,
evidence satisfactory to Hyperion of their authority to so act must be
submitted with the Letter of Transmittal.
 
  Any financial institution that is a participant in the book-entry transfer
facility for the Old Notes, The Depository Trust Company ("DTC"), may make
book-entry delivery of Old Notes by causing DTC to transfer
such Old Notes into the Exchange Agent's account with respect to the Old Notes
in accordance with DTC's procedures for such transfer. Although delivery of
Old Notes may be effected through book-entry transfer into the Exchange
Agent's account at DTC, an appropriate Letter of Transmittal with any required
signature guarantee and all other required documents must in each case be
transmitted to and received and confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old
Notes will be determined by Hyperion in its sole discretion, which
determination will be final and binding. Hyperion reserves the absolute right
to reject any and all Old Notes not properly tendered or any Old Notes
Hyperion's acceptance of which would, in the opinion of counsel for Hyperion,
be unlawful. Hyperion also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Old Notes. Hyperion's
interpretation of the terms and conditions of the Exchange Offer (including
the instructions in the Letter of Transmittal) will be final and binding on
all parties. Unless waived, any defects or irregularities in connection with
tenders of Old Notes must be cured within such time as Hyperion shall
determine. Although Hyperion intends to notify holders of defects or
irregularities with respect to tenders of Old Notes, neither Hyperion, the
Exchange Agent nor any other person shall incur any liability for failure to
give such notification. Tenders of Old Notes will not be deemed to have been
made until such defects or irregularities have been cured or waived. Any Old
Notes received by the Exchange Agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering holders, unless otherwise
provided in the Letter of Transmittal, as soon as practicable following the
Expiration Date.
 
  In addition, Hyperion reserves the right in its sole discretion to purchase
or make offers for any Old Notes that remain outstanding subsequent to the
Expiration Date or, as set forth below under "Conditions," to terminate the
Exchange Offer and, to the extent permitted by applicable law, purchase Old
Notes in the open market, in privately negotiated transactions or otherwise.
The terms of any such purchases or offers could differ from the terms of the
Exchange Offer.
 
  By tendering, each holder will also represent to Hyperion (i) that the New
Notes acquired pursuant to the Exchange Offer are being obtained in the
ordinary course of business of the person receiving such New Notes, whether or
not such person is the holder, (ii) that neither the holder nor any such
person has an arrangement or understanding with any person to participate in
the distribution of such New Notes and (iii) that neither the holder nor any
such other person is an "affiliate," as defined in Rule 405 under the
Securities Act, of Hyperion, or that if it is an "affiliate," it will comply
with the registration and prospective delivery requirements of the Securities
Act to the extent applicable.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date, or (iii) who cannot complete the procedures for book-entry
transfer of Old Notes to the Exchange Agent's account with DTC prior to the
Expiration Date, may effect a tender if:
 
  (a) The tender is made through an Eligible Institution;
 
 
                                      24
<PAGE>
 
  (b) On or prior to the Expiration Date, the Exchange Agent receives from
      such Eligible Institution a properly completed and duly executed Notice
      of Guaranteed Delivery (by facsimile transmission, mail or hand
      delivery) setting forth the name and address of the holder, the
      certificate number(s) of such Old Notes (if possible) and the principal
      amount of Old Notes tendered, stating that the tender is being made
      thereby and guaranteeing that, within five business trading days after
      the Expiration Date, (i) the Letter of Transmittal (or facsimile
      thereof) together with the certificate(s) representing the Old Notes
      and any other documents required by the Letter of Transmittal will be
      deposited by the Eligible Institution with the Exchange Agent, or (ii)
      that book-entry transfer of such Old Notes into the Exchange Agent's
      account at DTC will be effected and confirmation of such book-entry
      transfer will be delivered to the Exchange Agent; and
 
  (c) Such properly completed and executed Letter of Transmittal (or
      facsimile thereof), as well as the certificate(s) representing all
      tendered Old Notes in proper form for transfer and all other documents
      required by the Letter of Transmittal, or confirmation of book-entry
      transfer of the Old Notes into the Exchange Agent's account at DTC, are
      received by the Exchange Agent within five business trading days after
      the Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
  The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offer:
 
  The holder tendering Old Notes exchanges, assigns and transfers the Old
Notes to the Company and irrevocably constitutes and appoints the Exchange
Agent as the holder's agent and attorney-in-fact to cause the Old Notes to be
assigned, transferred and exchanged. The holder represents and warrants to the
Company and the Exchange Agent that (i) it has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire the New
Notes in exchange for the Old Notes, (ii) when the Old Notes are accepted for
exchange, the Company will acquire good and unencumbered title to the Old
Notes, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim, (iii) it will, upon request, execute and
deliver any additional documents deemed by the Company to be necessary or
desirable to complete the exchange, assignment and transfer of tendered Old
Notes and (iv) acceptance of any tendered Old Notes by the Company and the
issuance of New Notes in exchange therefor will constitute performance in full
by the Company of its obligations under the Registration Rights Agreement and
the Company will have no further obligations or liabilities thereunder to such
holders (except with respect to accrued and unpaid Liquidated Damages, if
any). All authority conferred by the holder will survive the death or
incapacity of the holder and every obligation of the holder will be binding
upon the heirs, legal representatives, successors, assigns, executors and
administrators of the holder.
 
  Each holder will also certify that it (i) is not an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act or that, if it
is an "affiliate," it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable, (ii) is
acquiring the New Notes offered in the ordinary course of its business and
(iii) has no arrangement with any person to participate in the distribution of
the New Notes.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  To withdraw a tender of Old Notes in the Exchange Offer, a telegram, telex,
facsimile transmission or letter indicating notice of withdrawal must be
received by the Exchange Agent at its address set forth herein prior to
 
                                      25
<PAGE>
 
5:00 p.m., New York City time, on the Expiration Date. Any such notice of
withdrawal must (i) specify the name of the person having tendered the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate number or numbers and principal amount of
such Old Notes), (iii) be signed by the holder in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Old
Notes register the transfer of such Old Notes into the name of the person
withdrawing the tender and (iv) specify the name in which any such Old Notes
are to be
registered, if different from that of the Depositor. If Old Notes have been
tendered pursuant to the procedure for book-entry transfer, any notice of
withdrawal must specify the name and number of the account at DTC to be
credited with the withdrawn Old Notes or otherwise comply with DTC's
procedures. All questions as to the validity, form and eligibility (including
time of receipt) of such notices will be determined by Hyperion, whose
determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no New Notes will be issued with respect thereto unless the
Old Notes so withdrawn are validly retendered. Any Old Notes which have been
tendered but which are not accepted for payment will be returned to the holder
thereof without cost to such holder as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offer. Properly withdrawn
Old Notes may be retendered by following one of the procedures described above
under "Procedures for Tendering" at any time prior to the Expiration Date.
 
UNTENDERED OLD NOTES
 
  Holders of Old Notes whose Old Notes are not tendered or are tendered but
not accepted in the Exchange Offer will continue to hold such Old Notes and
will be entitled to all the rights and preferences and subject to the
limitations applicable thereto under the Indenture. Following consummation of
the Exchange Offer, the holders of Old Notes will continue to be subject to
the existing restrictions upon transfer thereof and Hyperion will have no
further obligations to such holders, other than the Initial Purchaser, to
provide for the registration under the Securities Act of the Old Notes held by
them. To the extent that Old Notes are tendered and accepted in the Exchange
Offer, the trading market for untendered and tendered but unaccepted Old Notes
could be adversely affected.
 
EXCHANGE AGENT
 
  Bank of Montreal Trust Company, the Trustee under the Indenture, has been
appointed as Exchange Agent of the Exchange Offer. Questions and requests for
assistance, requests for additional copies of this Prospectus or of the Letter
of Transmittal and requests for Notices of Guaranteed Delivery should be
directed to the Exchange Agent addressed as follows:
 
   By Registered or Certified Mail,     By Facsimile: Bank of Montreal Trust
    by hand or by Overnight Courier      Company Attention: Corporate Trust
   Bank of Montreal Trust Company 77    Department (212) 701-7684 Confirm by
    Water Street New York, NY 10005           Telephone: (212) 701-7653
 Attention: Corporate Trust Department
 
  DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF
INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A
VALID DELIVERY.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by Hyperion. The principal
solicitation is being made by mail; however, additional solicitation may be
made by telegraph, telephone or in person by officers and regular employees of
Hyperion and its affiliates.
 
                                      26
<PAGE>
 
  Hyperion has not retained any dealer-manager in connection with the Exchange
Offer and will not make any payments to brokers, dealers or others soliciting
acceptances of the Exchange Offer. Hyperion, however, will pay the Exchange
Agent reasonable and customary fees for its services and will reimburse it for
its reasonable out-of-pocket expenses in connection therewith and will pay the
reasonable fees and expenses of holders in delivering their Old Notes to the
Exchange Agent.
 
  The cash expenses to be incurred in connection with the Exchange Offer will
be paid by Hyperion. Such expenses include fees and expenses of the Exchange
Agent and Trustee, accounting and legal fees and printing costs, among others.
 
  Hyperion will pay all transfer taxes, if any, applicable to the exchange of
Old Notes pursuant to the Exchange Offer. If, however, certificates
representing New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the Old Notes tendered, or
if tendered Old Notes are registered in the name of any person other than the
person signing the Letter of Transmittal, or if a transfer tax is imposed for
any reason other than the exchange of Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Upon consummation of the Exchange Offer, holders of Old Notes that were not
prohibited from participating in the Exchange Offer and did not tender their
Old Notes will not have any registration rights under the Registration Rights
Agreement with respect to such nontendered Old Notes and, accordingly, such
Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. In general, the Old Notes may not be offered
or sold, unless registered under the Securities Act and applicable state
securities laws, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not intend to register the Old Notes under the Securities Act.
Based on interpretations by the staff of the Commission with respect to
similar transactions, the Company believes that the New Notes issued pursuant
to the Exchange Offer in exchange for Old Notes may be offered for resale,
resold and otherwise transferred by any holder of such New Notes (other than
any such holder which is an "affiliate" of Hyperion within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business, such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes and neither the holder nor any other person
is engaging in or intends to engage in a distribution of the New Notes. If any
holder has any arrangement or understanding with respect to the distribution
of the New Notes to be acquired pursuant to the Exchange Offer, the holder (i)
could not rely on the applicable interpretations of the staff of the
Commission and (ii) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
Each broker-dealer that receives New Notes for its own account in exchange for
Old Notes must acknowledge that it will deliver a prospectus in connection
with any resale of its New Notes. See "Plan of Distribution." The New Notes
may not be offered or sold unless they have been registered or qualified for
sale under applicable state securities laws or an exemption from registration
or qualification is available and is complied with. The Company is required,
under the Registration Rights Agreement, to register the New Notes in any
jurisdiction requested by the holders, subject to certain limitations.
 
OTHER
 
  Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes are urged to
consult their financial and tax advisors in making their own decisions on what
action to take.
 
 
                                      27
<PAGE>
 
  Upon consummation of the Exchange Offer, holders of the Old Notes that were
not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes and, accordingly,
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon.
 
  The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and
to the best of the Company's information and belief, each person
participating in the Exchange Offer is acquiring the New Notes in its ordinary
course of business and has no arrangement or understanding with any person to
participate in the distribution of the New Notes to be received in the
Exchange Offer. In this regard, the Company will make each person
participating in the Exchange Offer aware (through this Prospectus or
otherwise) that if the Exchange Offer is being registered for the purpose of
secondary resale, any holder using the Exchange Offer to participate in a
distribution of New Notes to be acquired in the registered Exchange Offer (i)
may not rely on the staff position enunciated in Morgan Stanley and Co. Inc.
(avail. June 5, 1991) and Exxon Capital Holding Corp. (avail. May 13, 1988) or
similar letters and (ii) must comply with registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.
 
ACCOUNTING TREATMENT
 
  The New Notes will be recorded at the same carrying value as the Old Notes
as reflected in Hyperion's accounting records on the Exchange Date.
Accordingly, no gain or loss for accounting purposes will be recognized by
Hyperion. The expenses of the Exchange Offer will be expensed over the terms
of the New Notes.
 
                                USE OF PROCEEDS
 
  There will be no proceeds to the Company from the Exchange Offer.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
Company's audited Consolidated Financial Statements and the Notes thereto
appearing elsewhere in this Prospectus.
 
OVERVIEW
 
  The Company, through its Operating Companies, provides a competitive
alternative to the telecommunications services offered by the incumbent LECs
in its markets. Since its inception in October 1991, the Company has
experienced substantial growth, building from its original two partnerships
which served two markets to serving 13 markets and 19 cities through its 11
Operating Companies. The Operating Companies' customers are principally small,
medium and large businesses and government and educational end users as well
as IXCs. The Company is also building four additional networks which are
expected to serve 17 additional cities and which it will manage and operate
upon their expected completion during calendar 1996. Prior to May 16, 1996,
the Company also owned a 15.7% investment in the South Florida Partnership in
which it had no management responsibility, which investment the Company sold
on May 16, 1996. See "Business--Recent Developments." The Company believes
that its strategy of utilizing Local Partners to develop its networks has
allowed the Company to build networks with greater coverage, lower upfront and
ongoing costs and superior service and reliability.
 
 
                                      32
<PAGE>
 
  The Company's Operating Companies are made up of two wholly owned
subsidiaries and 11 investments where the Company owns 50% or less. Results of
the wholly owned subsidiaries are consolidated into the Company's financial
statements in this Prospectus. The Company's pro rata share of the results of
the Operating Companies where the Company owns 50% or less and the South
Florida Partnership are recorded under the caption "Equity in net loss of
joint ventures" in the Company's consolidated financial statements and results
of operations in this Prospectus utilizing the equity method of accounting.
Correspondingly, the Company's initial investments in these Operating
Companies and the South Florida Partnership are carried at cost, and
subsequently are adjusted for the Company's pro rata share of the Operating
Companies' and the South Florida Partnership's net losses, additional capital
contributions to the Operating Companies and the South Florida Partnership,
and distributions from the Operating Companies and the South Florida
Partnership to the Company. The Company is responsible for the design,
construction, management and operation of all of these Operating Companies and
receives management fees from the Operating Companies for its management and
network monitoring services. Management fees are determined by Local Partner
Agreements and vary depending upon the market. Management fees are accounted
for as revenues of the Company and reported in the Company's consolidated
financial statements. To date, the Company's principal source of revenues has
been derived through management fees from its Operating Companies.
 
  Since its inception, the Company, in conjunction with its Local Partners,
has made substantial investments in designing, constructing and enhancing the
Operating Companies' fiber optic networks. As of February 29, 1996, the
Company's networks and networks under construction had approximately 2,180
route miles, approximately 104,640 fiber miles and were connected to
approximately 808 buildings in 17 markets. The Operating Companies have also
installed five switches or remote modules which serve five markets, and the
Company has built its Network Operations and Control Center (the "NOCC") in
Coudersport, Pennsylvania, which provides for remote control, monitoring and
diagnosis of all of the Operating Companies' networks. According to industry
data, the Company believes it is the third largest CLEC in the United States
based upon its Operating Companies' networks' route miles or buildings
connected. Funding for the development of the Operating Companies has come
from investments by the Company and the Local Partners as well as from Fiber
Lease Financings which enable the Company to finance the building of fiber
optic plant through long-term leases. The combined capital invested through
December 31, 1995 in (i) the Operating Companies' networks, (ii) investments
in the Company related to the NOCC and other activities and (iii) the
Company's and its partners' investments in the South Florida Partnership has
totaled approximately $147 million. Due to savings achieved in the
construction of fiber optic networks by working with Local Partners, the
Company believes that building a
comparable level of network infrastructure without Local Partners would
require a substantially greater level of capital investment.
 
  The Company believes that as a result of the Telecommunications Act, the
potential market for its services has expanded significantly. According to the
Company's analysis of FCC data and its knowledge of the industry, the Company
estimates that the market for traditional access services and switched
services in its existing markets is approximately $4.8 billion. The Company
plans to deploy switches or remote switching modules in the balance of its
markets by the end of 1996 in order to more fully address this potential
market opportunity. See "Business" and "Regulation."
 
RECENT DEVELOPMENTS
 
  Sale of Partnership Interest in the South Florida Partnership. On May 16,
1996, the Company completed the sale of its 15.7% partnership interest in TCG
South Florida to Teleport Communications Group Inc. for an aggregate sales
price of approximately $11.6 million resulting in a pre-tax gain of
approximately $8.4 million. Amounts related to the South Florida Partnership
included in the Company's investments and equity in net loss of joint ventures
as of and for the nine months ended December 31, 1995 were approximately $2.9
million and ($0.6) million, respectively. As part of the transaction, the
Company was released from its covenant not to compete with respect to the
South Florida market. The Company plans to use the proceeds from the sale to
continue to expand and develop its existing markets, complete new networks
under construction and enter additional markets.

  National Service Agreement with Major IXC. The Company has entered into the
National Service Agreement with a major IXC pursuant to which the Company's
networks will be the IXC's preferred supplier of dedicated special access and
switched access transport services. The National Service Agreement requires
the Company to provide such services to the IXC at a discount from the
tariffed or published incumbent LEC rates. The National Service Agreement is
in effect in all of the Company's markets. The Company believes that only four
other CLECs have comparable National Service Agreements and have passed such
major IXC's network validation tests and operational readiness testing.
 
  Other Changes in Partnership Interests. The Company recently has entered
into an agreement or letter of intent pursuant to which the Company's
ownership interests in certain of the Operating Partnerships have recently
increased or are expected to increase in three markets. These transactions are
consistent with the Company's goal to own at least a 50% interest in its
Operating Partnerships in the future, and where appropriate the Company may
consider similar transactions from time to time in its other markets. Assuming
the successful completion of these transactions, Hyperion would own at least
50% of ten of its 17 then existing markets and markets under construction. See
"Business--Recent Developments."
 
  The consummation of one of these transactions is subject to the negotiation
and execution of definitive, binding agreements and to other terms and
conditions. No assurances can be given as to whether or when, or the terms
upon which, any such transaction will be consummated.
 
RESULTS OF OPERATIONS
 
 Nine Months Ended December 31, 1995 in Comparison with Nine Months Ended
December 31, 1994
 
  Revenues increased 156% to $2.5 million in the nine months ended December
31, 1995 from $1.0 million for the same period in the prior fiscal year. A
significant portion of the growth in revenues resulted from continued
expansion in the number and size of Operating Companies and a resultant
increase in management fees. In addition, the Company's first wholly-owned
Operating Company, which operates in the Vermont market (the "Vermont
Operating Company"), generated revenues during the entire nine months ended
December 31, 1995.
 
  Network operations expense increased 156% to $1.9 million in the nine months
ended December 31, 1995 from $0.7 million for the same period in the prior
fiscal year. Approximately $0.2 million of the increase was attributable to
the expansion of operations at the NOCC, including systems upgrades. Most of
the remaining increase was due to the Vermont Operating Company reporting
expenses relating to its operations for the entire nine-month period ended
December 31, 1995.
 
  Selling, general and administrative expense increased 11% to $2.4 million in
the nine months ended December 31, 1995 from $2.1 million for the same period
in the prior fiscal year. The majority of the increase is attributable to the
full nine-months of operations at the Vermont Operating Company. Otherwise,
corporate overhead remained relatively constant during the period, despite
growth in the number of Operating Companies managed by the Company.
 
  EBITDA increased 7% to ($1.8) million in the nine months ended December 31,
1995 from ($1.9) million for the same period in the prior fiscal year as a
result of increased revenues from management fees and the Vermont Operating
Company, which were only partially offset by increased operating costs.
 
  Depreciation and amortization expense increased 378% to $0.9 million in the
nine months ended December 31, 1995 from $0.2 million for the same period in
the prior fiscal year primarily as a result of increased capital expenditures
at the NOCC and the wholly-owned Operating Companies.
 
 
                                      34
<PAGE>
 
  Interest expense increased 81% to $4.2 million in the nine months ended
December 31, 1995 from $2.3 million for the same period in the prior fiscal
year. The increase was directly attributable to increased borrowings from
Adelphia which were used to fund investments in Operating Companies and the
South Florida Partnership, capital expenditures and the Company's operations.
All of the Company's interest expense was non-cash and was added to amounts
due to Adelphia.
 
  Equity in net loss of joint ventures increased by 134% to ($3.2) million in
the nine months ended December 31, 1995 from ($1.3) million for the same
period in the prior fiscal year as more nonconsolidated Operating Companies
began operations. The number of nonconsolidated Operating Companies paying
management fees to the Company increased from nine at March 31, 1995 to eleven
at December 31, 1995.
 
  Net income (loss) increased 73% from ($5.7) million for the nine-month
period ended December 31, 1994 to ($9.9) million for the same period in the
current fiscal year. The increase was primarily attributable to greater
interest expense, increased equity in the net losses of the Company's joint
ventures, and increased depreciation and amortization.
 
 Fiscal 1995 in Comparison with Fiscal 1994
 
  Revenues increased 307% from $0.4 million to $1.8 million from the year
ended March 31, 1994 ("Fiscal 1994") to the year ended March 31, 1995 ("Fiscal
1995"). A substantial portion of the increase in revenues resulted from growth
in the number of Operating Companies and the resulting management fees. The
number of nonconsolidated Operating Companies paying management fees to the
Company increased from three at March 31, 1994 to nine at March 31, 1995. The
Vermont Operating Company commenced operations and generated revenues during
Fiscal 1995.
 
  Network operations expense increased 319% from $0.3 million in Fiscal 1994
to $1.4 million in Fiscal 1995. This increase was primarily the result of the
expansion of the Company's NOCC staff and technical resources staff required
to support an increasing number of Operating Companies that were operating
during Fiscal 1995.
 
  Selling, general, and administrative expense increased 23% from $2.0 million
in Fiscal 1994 to $2.5 million in Fiscal 1995. The change was primarily due to
increases in accounting, regulatory and marketing personnel to support
increased management and monitoring operations. A portion of this increase was
also attributable to additional personnel and related costs for the
commencement of operations at the Vermont Operating Company.
 
  EBITDA decreased by $0.2 million or 10% from ($1.9) million in Fiscal 1994
to ($2.1) million in Fiscal 1995. This decrease was the result of increasing
expenses incurred in advance of new networks becoming operational and
therefore more than offsetting increased revenues.
 
  Depreciation and amortization expense increased by 145% from $0.2 million in
Fiscal 1994 to $0.5 million in Fiscal 1995. This increase was directly
attributable to the addition of telecommunications monitoring equipment
totaling $1.5 million and the expansion of the telecommunications networks in
the Company's wholly-owned Operating Companies.
 
  Interest expense increased by 53% from $2.2 million in Fiscal 1994 to $3.3
million in Fiscal 1995. The increase was primarily due to the increase in
borrowings from Adelphia to fund investments in Operating Companies and the
South Florida Partnership, capital expenditures and the Company's operations.
All of the Company's interest expense was non-cash and was added to amounts
due to Adelphia.
 
  Equity in net loss of joint ventures increased by ($1.3) million from ($0.5)
million in Fiscal 1994 to ($1.8) million in Fiscal 1995. The increase was
primarily due to the six Operating Companies beginning operations in Fiscal
1995.
 
  Net income (loss) increased ($3.0) million from ($4.7) million in Fiscal
1994 to ($7.7) million in Fiscal 1995. This increase was primarily the result
of the increase in the Company's operating loss, greater interest expense and
increased equity in the net losses of the Company's joint ventures.

SUPPLEMENTARY OPERATING COMPANY REVENUE ANALYSIS
 
  The Company believes that working with Local Partners to develop markets
enables the Company to build larger networks in a rapid and cost effective
manner. In pursuit of this strategy, the Company has entered into nine joint
ventures with Local Partners where the Company owns 50% or less of each
partnership or corporation. As a result of the Company's ownership position in
these joint ventures, a substantial portion of the Operating Companies'
results are reported by the Company on the equity method of accounting for
investments which only reflects the Company's pro rata share of net income or
loss of the Operating Companies. Because all of the assets, liabilities and
results of operations of the Operating Companies are not presented in the
Company's consolidated financial statements, financial analysis of these
Operating Companies based upon the Company's results does not represent a
complete measure of the growth or operations of the Operating Companies.
 
  In order to provide an additional measure of the growth and performance of
all of the Company's networks, management of the Company analyzes a variety of
financial information including revenues. Revenues of the Operating Companies
indicate the level of activity in the Company's networks. Capital expenditures
of the Operating Companies along with network construction statistics, such as
route miles and buildings connected, indicate the extensiveness of the
Company's construction and expansion efforts in those markets. The financial
information set forth below, however, is not indicative of the Company's
overall financial position and investors should not place undue reliance on
such information when considering an investment in the Senior Notes.
 
  The Operating Companies have shown substantial growth in revenues since the
Company's inception in October 1991. Total combined revenues for the Operating
Companies has increased approximately 237% from approximately $1.0 million in
Fiscal 1994 to approximately $3.3 million in Fiscal 1995. For the nine months
ended December 31, 1995, the Operating Companies' revenues totaled
approximately $5.5 million as compared with approximately $1.8 million for the
comparable period in 1994, representing an increase of approximately 201%. The
Operating Companies' revenues for the fiscal quarter ended December 31, 1995
were approximately $2.0 million. Multiplying the Operating Companies' revenues
in the latest fiscal quarter by four ("Latest Quarter Annualized Revenues")
provides an indication of the potential annual revenue base of the Operating
Companies for that quarterly period. The Operating Companies' Latest Quarter
Annualized Revenues were approximately $8.2 million. This figure is
approximately 151% greater than the Operating Companies' actual annual revenue
for Fiscal 1995. There can be no assurance, however, that the Operating
Companies will continue to experience revenue growth at this rate, or at all.
See "Risk Factors--Negative Cash Flow and Operating Losses; Limited History of
Operation." Furthermore, there can be no assurance that the Company will be
able to benefit from such growth in revenues if such growth occurs. See "Risk
Factors--Holding Company Structure; Inability to Access Cash Flow."

LIQUIDITY AND CAPITAL RESOURCES
 
  The development of the Company's business and the installation and expansion
of the Operating Companies' networks, combined with the construction of the
Company's NOCC, have resulted in substantial capital expenditures and
investments during the past several years. Capital expenditures by the Company
were $3.1 million, $2.9 million and $4.5 million for Fiscal 1994, Fiscal 1995
and the nine months ended December
 
                                      36
<PAGE>
 
31, 1995, respectively. Further, investments made in the Company's
nonconsolidated Operating Companies and the South Florida Partnership were
$5.5 million, $7.5 million and $9.1 million in Fiscal 1994, Fiscal 1995 and
the nine months ended December 31, 1995, respectively. The Company expects
that it will continue to have substantial capital and investment requirements.
The Company also expects to have to continue to fund operating losses as the
Company develops and grows its business. See "Risk Factors--Significant Future
Capital Requirements."
 
  Since its inception, substantially all of the Company's direct expenditures
for network construction, expansion, operations and investments have been
funded by Adelphia, which had invested as of December 31, 1995 approximately
$49.9 million in loans (including accrued interest) to the Company and $5.7
million in fiber network construction leased back to certain Operating
Companies and the South Florida Partnership. In addition, Local Partners and
the Company's partners in the South Florida Partnership in the aggregate have
contributed approximately $64.8 million as their pro rata investment in those
networks. These partners have also provided additional capital of $26.2
million for the construction of the Company's and the South Florida
Partnership's networks through the partnership agreements by funding the fiber
construction of the network and then leasing the fiber back to the partnership
in long-term, renewable agreements (the "Fiber Lease Financings").
Collectively, Adelphia's and the Company's partners' investments and the Fiber
Lease Financings have totaled $146.6 million from the Company's inception
through December 31, 1995. Due to savings achieved in the construction of
fiber optic networks by working with Local Partners, the Company believes that
building a comparable level of network infrastructure without Local Partners
would require a substantially greater level of capital investment.
 
  The Company has experienced negative cash flow since its inception. A
combination of operating losses, the substantial capital investments required
to build the Company's wholly-owned networks and its state-of-the-art NOCC,
and incremental investments in the Operating Companies has resulted in
substantial negative cash flow. See "Risk Factors--Negative Cash Flow and
Operating Losses; Limited History of Operations." Funding of the Company's
cash flow deficiency was principally accomplished through additional
borrowings from Adelphia. Interest and fees on this unsecured credit facility
are based upon the weighted average cost of unsecured borrowings of Adelphia.
The average interest rate charged for all periods through December 31, 1995
was 11.3% (excluding fees charged which were based on the amount borrowed). As
of December 31, 1995, no cash payments for interest or fees have been made by
the Company to Adelphia. The total cumulative amount of interest converted to
note principal at December 31, 1995 was $8.1 million. See "Certain
Relationships and Transactions."
 
  The competitive local telecommunication service business is a capital-
intensive business. The Company's operations have required and will continue
to require substantial capital investment for (i) the installation of
electronics for switched services in the Company's networks, (ii) the
expansion and improvement of the Company's NOCC and (iii) the design,
construction and development of additional networks. The Company plans to make
substantial capital investments and investments in Operating Companies in
connection with the deployment of switches in all of its operating markets by
the end of 1996, the expansion of existing markets and the construction and
development of new markets. Expansion of the Company's networks will include
the geographic expansion of the Company's existing clusters and the
development of new markets. The Company expects to build networks in
approximately ten additional markets by the end of 1997. The Company estimates
that it will require approximately $110 million to $115 million to fund
anticipated capital expenditures, working capital requirements and operating
losses of the Company and to make investments in existing and new Operating
Companies during calendar 1996 and 1997. The Company expects that it will have
adequate resources to fund such expenditures through the proceeds from the
sale of the Units and internal sources of funds including cash flow from
operations. The Company also expects to raise additional capital through a
private or public equity placement in the next 12 to 18 months. There can be
no assurance, however, as to the availability of funds from internal cash flow
or from the private or public equity markets. See "Risk Factors--Significant
Future Capital Requirements."
 
 
                                      37
<PAGE>
 
  In addition, the Company expects that pro rata investments by the Company
and its Local Partners as well as Fiber Lease Financings and anticipated
vendor financings will be adequate to fund the requirements of the Operating
Companies for capital expenditures, operating losses and working capital for
existing networks, networks currently under construction and certain of the
Company's planned additional markets during calendar years 1996 and 1997.
There can be no assurance as to the availability of funds from internal cash
flow, the Local Partners or other external sources or as to the terms of such
financings. In addition, the Indenture provides certain restrictions upon the
Company's ability to incur additional indebtedness. The Company's inability to
fund pro rata investments required for the Operating Companies could result in
a dilution of the Company's interest in the individual Operating Companies or
could otherwise have a material adverse effect upon the Company and/or the
Operating Companies.
 
EFFECT OF NEW ACCOUNTING STANDARDS
 
  In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 121 "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." In
accordance with SFAS No. 121, the Company reviews the carrying amounts of its
long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. Measurement of any
impairment would include a comparison of estimated future operating cash flows
anticipated to be generated during the remaining life of the assets with their
net carrying value. The adoption of SFAS No. 121 in the year ended March 31,
1995 had no effect on the consolidated financial statements of the Company.
 
IMPACT OF INFLATION
 
  The Company does not believe that inflation has had a significant impact on
the Company's consolidated operations or on the operations of the Operating
Companies over the past three fiscal years.
 
                                   BUSINESS
 
INDUSTRY HISTORY
 
  Deregulation, technological change and the increasingly information
intensive nature of the United States economy have significantly expanded the
role of telecommunications in business. In particular these changes have
accelerated the growth of certain aspects of the telecommunications market.
For example, industry sources estimate that voice traffic is growing at a rate
of approximately seven percent per year while data communications are growing
at three to five times that rate due to the increase in computerized
transaction processing and video applications, the movement to distributed
data processing and the rise of decentralized management structures, all of
which require the transmission of large amounts of information with speed,
accuracy and reliability.
 
  The present structure of the U.S. telecommunications market resulted largely
from the divestiture of the "Bell System" in 1984 (the "Divestiture"). As part
of the Divestiture, seven RBOCs were created to offer services in
geographically defined areas called LATAs. The RBOCs were separated from the
long distance provider, AT&T, resulting in the creation of two distinct
industries: local exchange and interexchange (commonly known as long
distance). The Divestiture facilitated direct, open competition in the long
distance segment of the telecommunications market; however, it did not promote
competition in the local telecommunications market. Nonetheless, several
factors have served to promote competition in the local telecommunications
market and the emergence of competitive access providers ("CAPs"), including
(i) the incumbent LECs' monopoly position and regulated pricing structure,
which provided little incentive for incumbent LECs to reduce prices, improve
service or upgrade their networks, (ii) customer demand for an alternative to
the incumbent LEC monopoly, which demand grew rapidly and was spurred in part
by the development of competitive activities in the long distance market and
increasing demand for high quality, reliable services, (iii) the advancement
of fiber optic and digital electronic technologies (such as ATM and
 
                                      38
<PAGE>
 
SONET), which combined the ability to transmit voice, data and video at high
speeds with greatly increased capacity and reliability as compared to the
incumbent LECs' copper-based networks and (iv) the significant fees, called
"access charges," IXCs are required to pay to incumbent LECs for originating
and terminating calls on the incumbent LEC networks.
 
  Established in the mid 1980s, CAPs were among the first competitors in the
local telecommunications market. CAPs provided non-switched services (i.e.,
dedicated special access and private line) by installing fiber optic
facilities connecting IXCs POPs within a metropolitan area and, in some cases,
connecting end users (primarily large businesses and government agencies) with
IXCs. CAPs used the substantial capacity and economies of scale inherent in
fiber optic cable to offer customers service that was generally less expensive
and of a higher quality than could be obtained from incumbent LECs. In
addition, CAPs offered customers shorter installation and repair intervals and
improved service reliability in comparison to incumbent LECs.
 
  The Telecommunications Act, which was adopted on February 8, 1996, is
considered to be the most comprehensive reform of the nation's
telecommunications laws since the Communications Act of 1934 and will
substantially affect the development of competition for local telephone
services. Among the more significant provisions of the Telecommunications Act
are (i) the removal of legal barriers to entry in local telephone markets,
(ii) the requirement that incumbent LECs "interconnect" with competitors,
(iii) the establishment of procedures for incumbent LEC entry into new
markets, such as long distance and cable television, (iv) the relaxation of
the regulation of telecommunication services provided by incumbent LECs and
others and (v) the establishment of a subsidy mechanism for the preservation
of universal telephone service. The Company believes the Telecommunications
Act will position the competitive local telecommunications business for
significant growth as CAPs evolve into CLECs by expanding their networks and
service offerings. Of the $32 billion of access fees paid by IXCs to LECs in
1994, CAPs accounted for $294 million or less than 1%. The Company expects
that the anticipated entry of incumbent LECs into the long distance business
will increase this penetration rate if IXCs seek alternatives to incumbent
LECs as sources of access to their customers. Regulatory reform, together with
increasing customer demand, will create more opportunities for CLECs to
introduce additional services, expand their networks and address a larger
customer base. The Company believes that these changes afford CLECs the
potential to grow significantly over the next several years. The Company
believes, based on data compiled by the FCC, that the passage of the
Telecommunications Act combined with earlier state regulatory developments
have increased the potential market for CLECs from approximately $26.3 billion
to approximately $97.1 billion annually due to the opening of the market for
switched services. This new market opportunity will permit CLECs to offer a
full range of local telecommunications services including local dial tone,
local calls, custom calling features and intraLATA toll services for both
business and residential customers. See "Competition" and "Regulation--
Overview."
 
THE COMPANY
 
  Hyperion is a leading CLEC that designs, constructs, operates and manages
state-of-the-art, fiber optic networks and facilities. According to industry
data, the Company believes it operates one of the three largest CLECs in the
United States based upon route miles and buildings connected. The Company's
networks work in conjunction with IXCs such as AT&T, MCI, Sprint, WorldCom and
others in order to offer small, medium and large businesses, government and
education end users a broad array of integrated, high quality voice, video and
enhanced data communications services. The Company, through its 13 networks,
currently offers traditional access services and has also installed switches
or remote switching capability in five of its networks and plans to offer
switched services, including customer dial tone, in all of its operating
markets by the end of 1996. Three of the Company's networks also offer
enhanced data services to their customers such as frame relay and ATM data
transport. These services, along with the long distance services provided by
IXCs, enable the Company to provide an integrated telecommunications service
offering to network customers that is more reliable, has a superior level of
service and is priced lower relative to that of the incumbent LECs in the
markets served by the Company's networks.
 
  The Company currently manages and operates 13 networks which are primarily
clustered in three regions located in the eastern half of the United States
and which serve 19 cities with populations from at least 25,000 to
 
                                      39
<PAGE>
 
more than 600,000. The Company also has four new networks under construction
which will serve 17 additional cities and will be managed and operated by the
Company upon their expected completion in calendar year 1996. Eleven of the
Company's networks and three of its networks under construction are owned in
partnership with several major cable television operators including Tele-
Communications, Inc., Time Warner/Newhouse, Continental Cablevision, TKR
Cable, Lenfest Communications, Viacom, InterMedia Partners and
Multimedia/Gannett, and an electric utility, PECO Energy, owner of the
Philadelphia Electric Company. The Company believes that working with Local
Partners significantly reduces the cost and time in developing a network
through utilization of existing cable or utility facilities. The remaining two
operating networks and one network under construction are wholly owned by the
Company and lease fiber capacity from Adelphia to achieve similar time and
cost savings in developing the networks. Due to savings achieved in the
construction of fiber optic networks by working with Local Partners, the
Company believes that building a comparable level of network infrastructure
without Local Partners would require a substantially greater level of capital
investment.
 
  The Company has targeted markets primarily in the eastern half of the United
States where it can leverage the Company's existing network infrastructure and
take advantage of the economies of scale associated with operating networks in
contiguous markets. Since the Company's inception in October 1991, the Company
and its partners have invested approximately $147 million to build and develop
the overall network infrastructure. As of February 29, 1996, the Company's 13
operating networks served 19 cities, and along with the four networks under
construction, included approximately 2,180 route miles of fiber optic cable
and were connected to approximately 808 buildings. The Company intends to
increase the density of its existing network clusters and expand into new
geographical markets or clusters through the construction of approximately ten
additional networks by the end of 1997. The Company will continue to focus on
developing networks in conjunction with Local Partners and managing and
operating these networks on behalf of the Operating Companies. The Company's
goal for future partnerships is to maintain at least a 50% equity interest in
these networks. The Company has recently entered into a partnership agreement
amendment with TKR and a nonbinding letter of intent with InterMedia to
increase its equity interests to 50% or more in the Louisville, Lexington and
Nashville market. Assuming the successful completion of all of these
transactions, Hyperion would own at least 50% of ten of its 17 then existing
markets and markets under construction. See "--Recent Developments."
 
COMPANY STRATEGY
 
  The Company, through its networks, is a leading provider of integrated local
telecommunications services to small, medium and large businesses, government
and educational end users and IXCs in its existing markets. The Company
differentiates its service offering by partnering with local cable television
operators and utility companies to develop networks that will provide
customers with greater market coverage, lower costs and superior service. The
Company's networks leverage the IXCs' name recognition and reputation for
quality and reliability by becoming preferred suppliers for IXCs of local
telecommunications services in the Company's markets. The IXCs market their
long distance services in conjunction with the Company's local service
offerings to provide end users with a fully integrated telecommunications
service offering in all of the Company's operating markets. Principal elements
of the Company's network, market and customer strategies include:
 
 Network Strategy
 
  Develop a Rapid Entry/Low Cost Approach with Local Partners. The Company
works with a Local Partner in order to significantly reduce the cost and time
to construct a fiber optic network, enable the Company to rapidly begin
offering services and lower the overhead associated with operating and
maintaining the Company's networks. Advantages of building the Company's
networks with Local Partners include (i) sharing the cost of building the
fiber optic network with a cable television system or utility system which the
Company believes reduces the cost of aerial fiber construction by
approximately 62%, (ii) reducing the time and cost of obtaining access to
rights-of-way and building entrances and (iii) enabling the Company to
leverage the Local Partners' experience and capabilities for building and
maintaining fiber optic cables thereby significantly reducing the upfront and
ongoing costs of a fiber optic network. Through the partnerships, the Company
has financed its expansion at a lower cost relative to its competitors by
utilizing pro rata equity investments and Local
 
                                      40
<PAGE>
 
Partner financings of a significant portion of fiber construction. Local
Partners provide most of the funds for the fiber build in a network and lease
the fiber capacity back to the partnership under long-term agreements. The
partnership purchases and owns the electronic and customer premises equipment
associated with the networks.
 
  The Company is able to lower the cost of building fiber optic networks by
working with Local Partners who own existing communications networks and
organizations that design, build and maintain these networks. The Company
achieves savings in the design, construction and maintenance of these fiber
optic networks because a substantial portion of these activities are shared
with existing efforts of the Local Partner. A significant portion of the
upfront savings is achieved in the construction of the fiber optic network.
The Company believes that, based upon its experience of building fiber optic
networks with Local Partners, the Company is able to achieve approximately a
62% reduction in aerial fiber optic construction costs versus constructing an
aerial fiber optic network without a Local Partner. The Company estimates that
approximately 70% of its network construction will be aerial and that the
Company can achieve similar savings in underground construction where conduit
is available. These estimates are based upon historical experience, and there
can be no assurance that the Company will be able to achieve similar results
in future efforts. These cost savings are achieved primarily through the
sharing of pole attachment costs ("Pole Attachment Costs") and the elimination
of costs of the engineering and rearrangement of cables to prepare telephone
poles for the attachment of new fiber optic cable ("Make Ready Costs"). An
analysis of the estimated cost savings for the Company for one mile of aerial
construction is set forth in the following table.

  Build Broad Network Coverage. The Company intends to build substantially
larger networks than the networks of the CLECs it competes with in its
markets. As of February 29, 1996, in all of the markets in which the Company
and its networks operate, management believes that the Company has the
broadest network coverage in terms of route miles of any of its CLEC
competitors. The Company believes that expanded network coverage will enable
the Company to (i) provide broader and more reliable coverage for network
customers, (ii) carry a greater amount of traffic on its own networks rather
than on the networks of other carriers thereby increasing the Company's
revenues and profit margins, (iii) increase the potential market available to
the Company due to the greater number of buildings, LEC-COs and customers that
the Company's networks can service, (iv) improve the value of the Company's
networks to IXCs, cellular providers and new telecommunications providers such
as PCS operators that need wide backbone coverage, (v) offer services in areas
where there are fewer potential CLECs with facilities and (vi) leverage the
fixed cost structure of the Company's networks, particularly with regard to
network electronics such as switches.

 Market Strategy
 
  Expansion through Development of Network Clusters. The Company's networks
are located primarily in the eastern half of the United States. The Company
expects to continue to focus on this region due to the eastern location of the
Company's existing networks and the Company's NOCC and headquarters. The
Company also believes that the eastern half of the United States, particularly
the Northeast, has greater concentrations of large business, government and
education end users and telecommunications traffic. The Company intends to
build networks in ten additional markets located near existing clusters or in
one or more new clusters by the end of 1997. Management believes that there
are significant operating and marketing advantages to locating its networks in
clusters. Clustering enables the Company to (i) take advantage of economies of
scale in management, construction, network operations and sales and marketing,
(ii) optimize the networks' switching capacity by utilizing remote switch
capacity in nearby cities that do not have switches, (iii) offer services to
lower density traffic areas in which the Company's networks are less likely to
face strong competition from incumbent LECs and other CLECs and (iv) increase
the networks' ability to offer highly reliable, end-to-end connectivity on a
regional basis. The Company also believes that creating regional networks will
enable the Company to gain a greater share of higher margin long distance
transport traffic.
 
 Customer Strategy
 
  Develop Strategic Relationships with IXCs. The Company, through its
networks, provides customers with an integrated, one-stop shopping approach to
their telecommunications needs through its strategic relationships with IXCs
such as AT&T, MCI, Sprint, WorldCom and others. The goal of these
relationships is for the Company's networks to offer their local services in
conjunction with the long distance services of these relationship IXCs.
Management believes that working in partnership with IXCs instead of as a
competitor will be attractive to IXCs and enable the Company to (i) utilize
extensive market information from the IXCs regarding traffic patterns and
building requirements to more optimally construct and extend its networks,
(ii) work closely with IXC account teams to provide an integrated service
approach to end users, (iii) increase market penetration by capitalizing on
the IXCs' name recognition and (iv) lower sales and marketing costs by
utilizing the extensive marketing resources and salesforce of the IXCs to
market the networks' products and services. In pursuing this strategy, the
Company has entered into the National Service Agreement with a major IXC
pursuant to which the Company's networks will be the IXC's preferred supplier
of dedicated special access and switched access transport services. The
National Service Agreement requires the Company to provide such services to
the IXC at a discount from the tariffed or published LEC rates. The National
Service Agreement is currently in effect in three of the Company's markets and
the Company is currently negotiating with the major IXC to include all the
Company's markets by the end of 1996, provided the networks in these markets
pass certain quality, service and validation tests similar to those passed in
three markets currently operating under the National Service Agreement. See
"--Recent Developments."
 
  Expand Enhanced Service Provider Offerings. Three of the Company's networks
operate in partnership with !NTERPRISE, a leading, nationwide network
integrator that designs, develops and deploys state-of-the-art data networks
(including both network services and equipment) to support and enhance the
information systems with which the networks' customers operate their
businesses. Pursuant to the partnership agreements, !NTERPRISE co-markets
enhanced services, including frame relay, ATM data transport, business video
conferencing, private line data interconnect service and LAN connection and
monitoring services to the networks' customers in the networks' respective
markets. The Company believes that the partnerships with !NTERPRISE provide
the opportunity to offer network customers a full complement of enhanced
services more rapidly and without the Company incurring the cost and overhead
of establishing its own nationwide enhanced services marketing, sales and
installation effort. The Operating Companies intend to enter into additional
agreements with !NTERPRISE and other service integrators in the future.
 
RECENT DEVELOPMENTS
 
  Sale of Partnership Interest in the South Florida Partnership. On May 16,
1996, the Company completed the sale of its 15.7% partnership interest in TCG
South Florida to Teleport Communications Group, Inc. for an
 
                                      42
<PAGE>
 
aggregate sales price of approximately $11.6 million resulting in a pre-tax
gain of approximately $8.4 million. Amounts related to the South Florida
Partnership included in the Company's investments and equity in net loss of
joint ventures as of and for the nine months ended December 31, 1995 were
approximately $2.9 million and ($0.6) million, respectively. As part of the
transaction the Company was released from its covenant not to compete with
respect to the South Florida Market. The Company plans to use the proceeds
from the sale to continue to expand and develop its existing markets, complete
new networks under construction and enter additional markets.
 
  National Service Agreement with Major IXC. The Company has entered into the
National Service Agreement with a major IXC pursuant to which the Company's
networks will be the IXC's preferred supplier of dedicated special access and
switched access transport services. The National Service Agreement requires
the Company to provide such services to the IXC at a discount from the
tariffed or published incumbent LEC rates. As of April 15, 1996, the National
Service Agreement was in effect in three of the Company's markets, and the
Company is currently negotiating with the major IXC to include all the
Company's markets by the end of 1996, provided the networks in these markets
pass certain quality, service and validation tests similar to those passed in
the three markets operating under the National Service Agreement. The Company
believes that only five other CLECs have comparable National Service
Agreements and have passed such major IXC's network validation tests and
operational readiness testing.
 
  Other Changes in Partnership Interests. The Company recently has entered
into an agreement with TKR and a nonbinding letter of intent with InterMedia
pursuant to which the Company's ownership interests in certain of the
Operating Partnerships have recently increased or are expected to increase in
three markets. These transactions are consistent with the Company's goal to
own at least a 50% interest in its Operating Partnerships in the future, and
where appropriate the Company may consider similar transactions from time to
time in its other markets. Assuming the successful completion of all of the
transactions contemplated below, Hyperion would own at least 50% of ten of its
17 then existing markets and markets under construction.
 
  Pursuant to a letter of intent with TKR, dated as of January 29, 1996, and a
subsequent amendment to the related partnership agreement dated May 8, 1996,
the Company has agreed that it will make additional capital contributions to
its Louisville, Kentucky Operating Partnership (which will also operate the
Lexington, Kentucky network under construction) and has increased its
partnership ownership interest to 50%. The Company estimates that the required
additional capital contributions will be approximately $2.7 million.
 
  Pursuant to a nonbinding letter of intent with InterMedia, dated as of
February 12, 1996, the Company intends to increase its partnership ownership
interest in the Nashville, Tennessee Operating Partnership from 25% to at
least 51% and as much as 95% by purchasing interests held by its Local Partner
at the option of such partner.
 
  The consummation of the InterMedia transaction is subject to the negotiation
and execution of definitive, binding agreements, and both of the proposed
transactions are subject to other terms and conditions. No assurances can be
given as to whether or when, or the terms upon which, any such transaction
will be consummated.

OPERATING AGREEMENTS
 
  Generally, subsidiaries of the Company enter into partnership agreements
with Local Partners to take advantage of the benefits of building networks in
conjunction with local cable television or utility operators. The typical
Operating Partnerships are formed and operated pursuant to three key
agreements: (i) a partnership agreement between the Company or one of its
wholly-owned subsidiaries and a cable television operator or electric utility
(the "Local Partner Agreement"); (ii) a fiber capacity lease agreement between
the Local Partner and the Operating Partnership (the "Fiber Lease Agreement");
and (iii) a management agreement between the Operating Company and the Company
or one of its subsidiaries (the "Management Agreement"). One of the Operating
Partnerships and two of the Operating Corporations have also entered into
agreements with !NTERPRISE, a wholly-owned subsidiary of US West, to co-market
enhanced services.
 
 Local Partner Agreements
 
  Each Local Partner Agreement establishes the structure of the applicable
Operating Partnership by determining, among other things, the partner's
capital contribution requirements, capital structure, purpose and scope of
business activities, transfer restrictions, dissolution procedures, duration
and competition restrictions, as well as the voting and buy/sell rights and
rights of first refusal of the partners of the Operating Partnership.
 
  Ownership and Capital Contributions. The initial capital contributions and
percentage of ownership of the Operating Partnerships vary. Some of the Local
Partner Agreements establish maximum capital contributions such that each
partner's ultimate aggregate capital contribution is determined at the
Operating Partnership's inception. Initial capital contributions are paid on
an installment basis as determined by a management committee. Unless a
majority vote of the partners determines otherwise, capital contributions in
excess of the initial capital contribution are not required. Generally, the
percentage of ownership is also fixed at the Operating Partnership's
inception. Absent an agreement by the partners, generally, the only
circumstances that result in the dilution of such partner's ownership interest
are a partner's failure to make a capital contribution or its failure to
exercise a right of first refusal.
 
  Matters Requiring a Vote. Most partner votes of an Operating Partnership
require only a majority vote; however, a unanimous vote of the partners is
required for, among other things, expansion of the scope of the business
activities in the defined business area, admission of additional partners and
merger or consolidation with any other entity if the Operating Partnership is
not the surviving entity.
 
  Distributions. Generally, the Local Partner Agreements allow for
distributions to the partners; however, the Local Partner Agreements vary with
regard to the procedure for determining if, when and how much of a
 
                                      46
<PAGE>
 
distribution should be made. In one Local Partnership Agreement, the Company,
through its affiliate, controls such determinations. In the remaining Local
Partner Agreements, the partners or the partnership's Managing Committee makes
such determinations by either majority approval or unanimous consent.
 
  Transfer of Ownership. The Local Partner Agreements generally prohibit the
transfer of partnership interests, including most changes in control.
Generally, transfers of entire partnership interests to subsidiaries of a
partner's parent corporation and the sale or disposition of all or
substantially all of the stock or assets of a partner's parent are expressly
permitted in the typical Local Partner Agreement.
 
  Rights of First Refusal; Buy/Sell Agreements. The partners of most of the
Operating Partnerships also retain certain rights of first refusal and
buy/sell rights. Generally, after a specified period of time, either partner
may transfer its interest to an unrelated third party if such partner first
offers its interest to the other partner at the same terms and the other
partner elects not to purchase the interest. In addition, in most of the
Operating Partnerships, either partner can, after a specified period of time,
make an offer to the other partner(s) to sell its own interest. Within 30 days
of submitting a price, the other partner must respond to the offer indicating
its election to either accept the offer to buy or sell at the offered price.
Certain partners in two of the partnerships have the right after a specified
period of time to put their interest in the respective partnership (i) to the
other partners at an amount equal to the fair market value of such partner's
interest pursuant to one agreement and (ii) to the Company at an amount equal
to the partner's capital contributions plus interest less any distributions
pursuant to the other agreement.
 
  Term. Most of the Operating Partnerships were created in the last three and
half years and have a duration of 10 to 25 years unless earlier dissolved. Two
of the Local Partner Agreements contain provisions whereby the respective
Local Partner can terminate its interest, at such Local Partner's sole
discretion, prior to 2003. See "Risk Factors--Risks Associated with Joint
Ventures." Generally, each partner and certain of its affiliates are
restricted from competing with the Operating Partnership in the defined
business area so long as the partner is a partner plus two or three years
thereafter.
 
 Fiber Lease Agreements
 
  Generally, the Operating Partnerships lease fiber optic capacity from their
Local Partners. In some instances, the Operating Partnerships lease existing
fiber optic capacity and in other instances, the Operating Partnerships
request the Local Partners to construct new fiber optic capacity. Monthly
lease payments in both instances are based on the amortization of the Local
Partner's cost of construction and material costs over the term of the Fiber
Lease Agreement. Because construction and material costs are amortized over
the then current term of the Fiber Lease Agreement, it is possible for the
amount of a monthly lease payment to be significantly lower during a renewal
term unless the construction of additional fiber optic cable is scheduled for
such renewal term. Typically, the amount of the lease payments in a renewal
period equals the amount of monthly maintenance costs for the leased fiber
optic cable.
 
  Each of the Fiber Lease Agreements is in its initial term. The initial terms
vary from 5 to 25 years in length. The Fiber Lease Agreements contain various
renewal options. Generally, either party can terminate the Fiber Lease
Agreement at the end of the then current term if the terminating party
provides prior written notice to the other party.
 
  Throughout the term of the Fiber Lease Agreements and thereafter, title to
the fiber optic cable remains with the Local Partner. Similarly, the Operating
Partnerships retain title to all of their own electronics and switches that
become a part of the network. A Local Partner cannot sell the fiber subject to
the Fiber Lease Agreement to a third party unless its obligations under the
Fiber Lease Agreement are assumed by the third party.
 
 
                                      47
<PAGE>
 
 Management Agreements
 
  Generally, the Company or a wholly-owned subsidiary of the Company provides
the Operating Partnerships with the following services pursuant to the
Management Agreement for a specified fee: general management, monitoring,
marketing, regulatory processing, accounting, engineering designing, planning,
construction, maintenance, operations, service ordering and billing. The term
of the typical Management Agreement is three or five years and automatically
renews for continuous one-year periods unless one party provides the other
with written notice that it intends to terminate the agreement.
 
 Enhanced Service Agreements
 
  Three of the Operating Companies have entered into partnership with
!NTERPRISE (the "!NTERPRISE Partnerships") in order to provide enhanced
services such as frame relay, ATM data transport, business video conferencing,
private line data interconnect service and LAN connection and monitoring
services. The partners in the !NTERPRISE Partnerships are required to
contribute equal amounts in order to retain their 50% ownership interests. The
business area serviced by the !NTERPRISE Partnerships is the same as that
serviced by the applicable Operating Partnership. The partners and their
respective affiliates are also prohibited from competing for as long as the
partners are partners plus two years thereafter. In addition, the partners
have a right of first refusal with regard to the sale of partnership interests
and, under certain circumstances, may put their interest to the partnership.
Generally, the !NTERPRISE Partnerships have a 20 year duration.
 
MAJOR IXC CERTIFICATION
 
  A major IXC with which the Company has entered into the National Service
Agreement has established a certification process called Operational Readiness
Testing ("ORT") in order to determine whether a supplier's network, systems
and processes are capable of providing a level of service which meets such
major IXC's standards. ORT is a lengthy process comprised of the following
components: (i) Operational Readiness Assessment ("ORA"), (ii) Network
Validation Testing ("NVT") and (iii) Switch Network Validation Testing
("SNVT"). CLECs must pass such major IXC's ORT for access services to provide
access services to the major IXC and such major IXC's ORT for switched
services to provide switched services to such major IXC.
 
  ORA is a one-time, in-depth evaluation to review all of the Operating
Company's processes and to verify that procedures are in place to govern
operations from initial design and construction through day-to-day operations
and maintenance. ORA is meant to ensure that every aspect of the Operating
Company's operations can deliver a product of high quality and reliability.
 
  NVT is an ongoing evaluation process that continually evaluates existing
markets and potential markets. NVT reviews the networks' redundancy of power
supplies; the temperature, humidity and ambient condition controls; the fire
protection; the route diversity of the fiber network; the design of
electronics; the security and general appearance of the Operating Company's
facilities.
 
  SNVT is an ongoing review that evaluates the performance and quality of the
Operating Company's switching capabilities.
 
  The Company has successfully passed the NVT in Jacksonville and Louisville.
Passing these evaluations enables the Company's networks in such markets to
carry traditional dedicated access and switched access transport. The Company
is currently preparing for an ORA of its switch installations and a NVT of its
switch operations in two of its other markets. Passing the ORA and the NVT of
its switch operations in each market will enable the Company's networks in
those markets to carry switched traffic for such major IXC. The Company
believes that certifying the Operating Companies' switching operations will
significantly enhance the market opportunity for the Operating Companies'
services.

SALES AND MARKETING
 
  The Company targets its network sales and marketing activities at IXCs and
business, government and educational end users. The Company's IXC targets
include the major IXCs as well as smaller and regional IXCs. IXCs utilize the
Operating Companies' services primarily as a local component of their own
service offerings to end users. The Company also targets end users which
include small, medium and large businesses as well as government and
educational institutions. In many cases, the Company works in conjunction with
IXCs when marketing to these end users in order to leverage the name
recognition, marketing reputation and resources of IXCs. In order to increase
the value of the Company's networks to IXCs, the Company's networks do not
offer a competing long distance service offering to end users. The Company's
networks offer their services in accordance with tariffs filed with the FCC
for interstate services and state regulatory authorities for intrastate
services. The Operating Companies are classified as non-dominant carriers by
the FCC and therefore have substantial pricing flexibility and in many cases
may enter into customer and product specific agreements.
 
 IXC Customers
 
  The Company has national supplier agreements with all of the major IXCs. The
Company believes it can effectively provide IXCs with a full complement of
traditional access services as well as switched services. Factors that
increase the value of the Company's networks to IXCs include reliability,
state-of-the-art technology, route diversity, ease of ordering and customer
service. The Company also generally prices the services of an Operating
Company at a discount relative to the incumbent LEC. In order to further
complement the services provided to the IXCs, the Company integrates its
networks with IXC networks to enable the IXC to (i) access service, billing
and other data directly from the Company and (ii) electronically send
automated service requests to the Company.
 
  An important component of the Company's strategy is to work with major IXCs
to develop an integrated local and long distance service offering to end
users. The Company believes this strategy will provide greater access to the
IXCs' large customer base and enable the Operating Companies to leverage the
IXCs' name recognition and reputation for reliability and quality. In pursuing
this strategy, the Company has entered into the National Service Agreement
with a major IXC pursuant to which the Company's networks will be the IXCs
preferred supplier of dedicated special access and switched access transport
services in three of the Company's markets. The National Service Agreement
requires the Company to provide such services to the IXC at a discount from
the tariffed or published LEC rates. The Company and the major IXC are
currently negotiating to include all of the Company's markets by the end of
1996, provided the networks in these markets pass certain quality, service and
validation tests similar to those passed in the three markets currently
operating under the National Service Agreement.
 
  The Company currently utilizes national account representatives to market to
IXC customers since the major IXCs have established national or regional
groups to manage and coordinate their purchasing of access services. These
groups assess CLECs not only upon price, quality, service and ease of
provisioning in a particular market, but also upon size, scope of operations
and financial stability in order to maximize the leverage of their CLEC
relationships. The Company focuses on serving the Operating Companies' IXC
customers in all of the Company's markets with a view to establishing national
preferred vendor relationships. The terms and conditions applicable to
services ordered by IXCs are generally specified in agreements under which
some services can be terminated by the IXC on 60 days or less notice. The
Company believes that the Operating Companies are well positioned to serve the
IXCs and that the Operating Companies generally have good relationships with
their respective IXC.
 
 End Users
 
  Each Operating Company works in conjunction with IXCs to offer an integrated
package of local and long distance service offerings to end users. Initially,
the Operating Company offers high quality access services to these end users
in combination with an IXC's long distance offerings. Building on its success
with the end users,
 
                                      49
<PAGE>
 
the Operating Company attempts to increase the size and number of service
offerings it provides by working with customers to analyze the customers'
local telecommunications needs. In particular, the typical Operating Company
offers end users a variety of services, including local dial tone, frame
relay, ATM transport, business video conferencing and other services. The
Company believes that, based upon the Operating Companies' reputation
developed in conjunction with major IXCs, the Operating Companies will be able
to systematically increase their share of the end users' telecommunications
expenditures. The Company believes the networks will be able to compete for
end users' needs based upon price, reliability, product diversity, service and
custom solutions to end user needs. A significant component of an Operating
Company's reliability will be its ability to offer customers end-to-end SONET
ring construction for many localized applications. The Operating Companies'
construction of SONET rings combined with the Company's large network size
will enable the Operating Companies to offer superior coverage to the
incumbent LEC and many CLECs especially in second and third tier markets.
 
  End users are currently marketed through Company direct sales
representatives in each market. The national sales organization also provides
support for the local sales groups and develops new product offerings and
customized telecommunications applications and solutions which address the
specific requirements of particular customers. In addition, the Company
markets the Operating Companies' products through advertisements, media
relations, direct mail and participation in trade conferences. End users
typically commit to a service agreement for a term of three to five years
which is either renegotiated or automatically converted to a month-to-month
arrangement at the end of the contract term.
 
 Hyperion Enhanced Networks
 
  The Company develops applications in conjunction with the Operating
Companies that are not specific to an IXC's traditional business or to a
particular partnership metropolitan area as special bid Hyperion Enhanced
Networks ("HENs"). HEN services include special construction of IXC networks,
campus networks, private carriage networks and other similar network
applications. HEN customers are currently marketed through Company national
account representatives in conjunction with special IXC or information service
provider groups that manage special network, campus, or junction applications.
The terms and conditions for HENs are generally specified in agreements with
three to five year terms which automatically renew to month-to-month
arrangements at the end of contract terms.
 
NETWORK DEVELOPMENT AND DESIGN
 
  Prior to any network construction in a particular market, the Company's
corporate development staff reviews the demographic, economic, competitive and
telecommunications demand characteristics of the market. These characteristics
generally include market location, the size of the telecommunications market,
the number and size of business, institutional and government end users and
the economic prospects for the area. In addition, the Company also carefully
analyzes demand information provided by IXCs, including demand for end user
special access and volume of traffic from the LEC-CO and the IXC POPs. The
Company also analyzes market size utilizing a variety of data, including
available estimates of the number of interstate access and intrastate private
lines in the region. Such information is available from the FCC.
 
  If a particular market targeted for development is deemed to have
sufficiently attractive demographic, economic, competitive and
telecommunications demand characteristics, the Company's network planning and
design personnel, working in conjunction with the Company's Local Partner, or
Adelphia or one of Adelphia's affiliates, design a large regional network
targeted to provide access to the identified business, government and
institutional end user revenue base and to the IXC POPs and the LEC-COs in the
geographic area covered by the proposed network.
 
  The actual network design is influenced by a number of market, cost and
technical factors including:
 
  . Availability and ease of fiber deployment
  . Location of IXC POPs
 
                                      50
<PAGE>
 
  . Density of telecommunication revenue based upon IXC information
  . The Company's market information
  . Cost of construction
 
  The objective of the network design is to maximize revenue derived from
service to IXC POPs, LEC-COs and important customers in consideration of
network construction costs. In most cases, the Local Partner bears the costs
of construction for the required fiber, retains ownership of the fiber and
leases the fiber to the Operating Company. The fiber lease costs are
determined by amortizing the Operating Company's portion of the Local
Partner's cost of construction over the term of the Fiber Lease Agreement at
an assumed interest rate. This structure generally allows the Operating
Company to better match its capital costs to cash flows. See"--Fiber Lease
Agreements."
 
NETWORK CONSTRUCTION
 
  The Company's networks are constructed to cost-effectively access areas of
significant end user telecommunications traffic, as well as the POPs of most
IXCs and the majority of the LEC-COs. The Company establishes with its Local
Partner or Adelphia general requirements for network design including,
engineering specifications, fiber type and amount, construction timelines and
quality control. The Company's engineering personnel provide project
management, including contract negotiation and overall supervision of the
construction, testing and certification of all facilities. The construction
period for a new network varies depending upon the number of route miles to be
installed, the initial number of buildings targeted for connection to the
network, the general deployment of the network and other factors. Networks
that the Company has installed to date have generally become operational
within six to ten months after the beginning of construction.
 
NETWORK OPERATING CONTROL CENTER
 
  In Coudersport, Pennsylvania, the Company has built a NOCC that is equipped
with state-of-the-art system monitoring and control technology. The NOCC is a
single point interface for monitoring all of the Company's networks and
provisioning all services and systems necessary to operate the networks. The
NOCC currently supports all of the Company's networks including the management
of over 800 building connections, five switches or remote switching modules
and approximately 2,180 network route miles. The NOCC is designed to
accommodate the Company's anticipated growth in all existing markets as well
as in all the markets the Company plans to enter.
 
  The NOCC is utilized for a variety of network management and control
functions including monitoring, managing and diagnosing the Company's SONET
networks, central office equipment, customer circuits and signals and the
Company's switches and associated equipment. The NOCC is also the location
where the Company provisions, coordinates, tests and accepts all orders for
switched and dedicated circuit orders. In addition, the NOCC maintains the
database for the Company's circuits and network availability. Network
personnel at the NOCC also develop and distribute a variety of software
utilized to manage and maintain the networks.
 
EQUIPMENT SUPPLY
 
  The Company and the Operating Companies purchase fiber optic transmission
and other electronic equipment from Lucent Technologies, formerly AT&T Network
Systems ("Lucent"), Fujitsu, Tellabs, and other suppliers at negotiated
prices. The Company expects that fiber optic cable, equipment and supplies for
the construction and development of its networks will continue to be readily
available from Lucent, Fujitsu and other suppliers as required. The Company
has negotiated multi-year contracts for equipment with Lucent, Fujitsu, and
Tellabs. The Company and the Operating Companies have deployed two Lucent 5ESS
Switches ("5ESSs") and three remote switching modules in five of their current
markets. The Company and the Operating Companies plan to deploy seven
additional 5ESSs and one remote switching module during calendar 1996 and
additional 5ESSs and remote switching modules in each of the Company's future
operational markets.
 
                                      51
<PAGE>
 
CONNECTIONS TO CUSTOMER LOCATIONS
 
  Office buildings are connected by network backbone extensions to one of a
number of physical rings of fiber optic cable, which originate and terminate
at the Operating Company's central office. Signals are sent simultaneously on
both primary and alternate protection paths through a network backbone to the
Operating Company's central office. Within each building, Operating Company-
owned internal wiring connects the Operating Company's fiber optic terminal
equipment to the customer premises. Customer equipment is connected to
Operating Company-provided electronic equipment generally located where
customer transmissions are digitized, combined and converted to an optical
signal. The traffic is then transmitted through the network backbone to the
Operating Company's central office where it can be reconfigured for routing to
its ultimate destination on the network.
 
  The Operating Company locates its fiber optic equipment in space provided by
the building owner or, more typically, on a customer's premises. IXCs often
enter into discussions with building owners to allow the Company to serve the
IXCs' customers. This network configuration enables the Company to share
electronic equipment among multiple customers, causes little interruption for
customers during installation and maintenance and allows the Company to
introduce new services rapidly and at low incremental cost.
 
EMPLOYEES
 
  As of February 29, 1996, the Operating Companies and the Company employed a
total of 84 and 61 full-time employees, respectively, in support of the
Operating Companies' and the Company's operations. The Company also regularly
uses the services of its Local Partners, employees and contract technicians
for the installation and maintenance of its networks. None of the Operating
Companies' or the Company's employees is represented by a collective
bargaining agreement. The Company believes that the Operating Companies' and
the Company's relations with their respective employees are good.
 
PROPERTIES
 
  The Company leases its principal executive offices in Coudersport,
Pennsylvania and its offices in Pittsburgh, Pennsylvania. Additionally, the
Company owns its NOCC facilities, and leases certain office space from
Adelphia, in Coudersport, Pennsylvania.
 
  All of the fiber optic cable, fiber optic telecommunications equipment and
other properties and equipment used in the networks, are owned or leased by
the applicable Operating Company. See "--Company's Markets." 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. As
of December 31, 1995, the Company's total telecommunications equipment in
service consist of fiber optic telecommunications equipment, fiber optic
cable, furniture and fixtures, leasehold improvements and construction in
progress. Such properties do not lend themselves to description by character
and location of principal units.
 
  Substantially all of the fiber optic telecommunications equipment used in
the Company's networks is housed in multiple leased facilities in various
locations throughout the metropolitan areas served by the Company. The Company
believes that its properties and those of its Operating Companies are adequate
and suitable for their intended purpose.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any pending legal proceedings except for
claims and lawsuits arising in the normal course of business. The Company does
not believe that these claims or lawsuits will have a material effect on the
Company's financial condition or results of operations.
 
 
                                      52
<PAGE>
 
                                  COMPETITION
 
  The Company operates in a highly competitive environment and has no
significant market share in any market in which it operates. In each of the
areas served by an Operating Company, services similar to those offered by the
Operating Company are offered by the incumbent LEC serving that area.
Incumbent LECs have long-standing relationships with their customers, have far
greater technical and financial resources and provide services that an
Operating Company may not currently be authorized by state regulators to
offer. See "Regulation--State Regulation." Following the enactment of the
Telecommunications Act, there has been significant merger activity among the
RBOCs which will result in competitors with even greater financial resources
and geographic scope than currently faced by the Company. In addition, in many
markets, the incumbent LEC currently is excused from paying license or
franchise fees or pays fees materially lower than those required to be paid by
the Operating Companies.
 
  While new business opportunities will be made available to the Company
through the Telecommunications Act and other federal and state regulatory
initiatives, regulators are likely to provide the incumbent LECs with an
increased degree of flexibility with regard to pricing of their services as
competition increases. If the incumbent LECs elect to lower their rates and
can sustain lower rates over time, this may adversely affect the revenues of
the Operating Companies and the Company by placing downward pressure on the
rates the Operating Companies can charge. The Company believes this effect
will be offset by the increased revenues available by offering new services,
but if future regulatory decisions afford the LECs excessive pricing
flexibility or other regulatory relief, such decisions could have a material
adverse effect on the Company.
 
  Competition for the Company's and the Operating Companies' services are
based on price, quality, network reliability, service features and
responsiveness to customer needs. The Company believes that its management
expertise, coupled with its highly reliable, state-of-the-art digital networks
and back-office infrastructure, which offer significant transmission capacity
at competitive prices, will allow it to compete effectively with the incumbent
LECs, which may not yet have fully deployed fiber optic networks in many of
the Company's target markets. The Company believes that the Operating
Companies price their services at a modest discount compared to the prices of
incumbent LECs while providing a higher level of customer service. The
Company's networks provide diverse access routing and redundant electronics,
design features not widely deployed by the incumbent LEC networks at the
present time. However, as incumbent LECs continue to upgrade their networks,
any competitive advantage held by the Company due to the superiority of its
facilities may diminish.
 
  Other current or potential competitors of the Company's networks include
other CLECs, IXCs, wireless telecommunications providers, microwave carriers,
satellite carriers, private networks built by large end users and cable
television operators or utilities in markets in which the Company has not
partnered with one or the other. In many markets served by the Company, one or
more CLECs already are providing service. Furthermore, the three major IXCs
have announced ambitious plans to enter the local exchange market. There is no
assurance that these IXCs will choose to obtain local services from the
Operating Companies in the Company's markets. In addition, the
Telecommunications Act requires all local exchange providers, including new
entrants, to offer their services for resale. See "Regulation--
Telecommunications Act of 1996." This requirement permits companies to enter
the market for local telecommunications services without investing in new
facilities, thereby increasing the number of likely competitors in any given
market, and enables the IXCs to provide local services by reselling the
service of the incumbent LEC rather than using services provided by the
Company.
 
                                  REGULATION
 
OVERVIEW
 
  Telecommunications services provided by the Company and its networks are
subject to regulation by federal, state and local government agencies. At the
federal level, the FCC has jurisdiction over interstate services, which
constitute a majority of the Operating Companies' current services. Interstate
services, for the purpose of determining FCC jurisdiction, are communications
that originate in one state and terminate in another
 
                                      53
<PAGE>
 
state or foreign country. State regulatory commissions exercise jurisdiction
over intrastate services. Intrastate services are communications that
originate and terminate in the same state. Additionally, municipalities and
other local government agencies may regulate limited aspects of the Company's
business, such as use of rights-of-way.
 
TELECOMMUNICATIONS ACT OF 1996
 
  On February 8, 1996, the Telecommunications Act of 1996 was signed into law
and is considered to be the most comprehensive reform of the nation's
telecommunications laws since the Communications Act of 1934. The
Telecommunications Act will result in substantial changes in the marketplace
for voice, data and video services. These changes will open the local exchange
market to competition and will result in a substantial increase in the
addressable market for the Company's networks. Among its more significant
provisions, the Telecommunications Act (i) removes legal barriers to entry in
local telephone markets, (ii) requires incumbent LECs to "interconnect" with
competitors, (iii) establishes procedures for incumbent LEC entry into new
markets, such as long distance and cable television, (iv) relaxes regulation
of telecommunications services provided by incumbent LECs and all other
telecommunications service providers, and (v) directs the FCC to establish a
subsidy mechanism for the preservation of universal service.
 
 Removal of Entry Barriers
 
  Prior to enactment of the Telecommunications Act, many states limited the
services that could be offered by a company competing with the incumbent LEC.
See "--State Regulation." In these states, the incumbent LEC retained a
monopoly over basic local exchange services pursuant to state statute or
regulatory policy. In states with these legal barriers to entry, the Company
had been limited to the provision of dedicated telecommunications services,
which constitutes only a small portion of the local telephone market.
 
  The Telecommunications Act prohibits state and local governments from
enforcing any law, rule or legal requirement that prohibits or has the effect
of prohibiting any person from providing interstate or intrastate
telecommunications services. States retain jurisdiction under the
Telecommunications Act to adopt laws necessary to preserve universal service,
protect public safety and welfare, ensure the continued quality of
telecommunications services and safeguard the rights of consumers.
 
  This provision of the Telecommunications Act should enable the Operating
Companies to provide a full range of local telecommunications services in any
state. The Operating Companies will continue their policy of not providing
long distance services that compete with the major IXCs in order to enable the
Company to work with IXCs to provide an integrated local and long distance
service offering to end users. Although the Operating Companies will be
required to obtain certification from the state regulatory commission in
almost all cases, the Telecommunications Act limits substantially the ability
of a state commission to deny a request for certification filed by an
Operating Company. While this provision of the Telecommunications Act expands
significantly the markets available to the Operating Companies, it also
reduces the barriers to entry by other potential competitors and therefore
increases the level of competition the Operating Companies will face in all
their markets. See "Competition."
 
 Access and Interconnection with LEC Facilities
 
  A company cannot compete effectively with the incumbent LEC in the market
for switched local telephone services unless it is able to connect its
facilities with the incumbent LEC and obtain access to certain essential
services and resources under reasonable rates, terms and conditions. Incumbent
LECs historically have been reluctant to provide these services voluntarily
and generally have done so only when ordered to by state regulatory
commissions.
 
  The Telecommunications Act imposes a number of access and interconnection
requirements on all local exchange providers, including CLECs, with additional
requirements imposed on incumbent LECs. These requirements will provide access
to certain networks under reasonable rates, terms and conditions.
Specifically,
 
                                      54
<PAGE>
 
the Telecommunications Act requires the FCC to adopt rules within six months
under which LECs must provide the following:
 
  Telephone Number Portability. Telephone number portability enables a
customer to keep the same telephone number when the customer switches local
exchange carriers. New entrants are at a competitive disadvantage without
telephone number portability because of inconvenience and costs to customers
that must change numbers.
 
  Dialing Parity. All LECs must provide dialing parity, which means that a
customer calling to or from a CLEC network cannot be required to dial more
digits than is required for a comparable call originating and terminating on
the LEC's network.
 
  Reciprocal Compensation. The duty to provide reciprocal compensation means
that LECs must terminate calls that originate on competing networks in
exchange for a given level of compensation and that they are entitled to
termination of calls that originate on their network for which they must pay a
given level of compensation.
 
  Resale. A LEC may not prohibit or place unreasonable restrictions on the
resale of its services. In addition, incumbent LECs must offer services to
resellers at a wholesale rate that is less than the retail rate charged to end
users.
 
  Access to Rights-of-Way. A LEC must provide access to its poles, ducts,
conduits and rights-of-way on a reasonable, nondiscriminatory basis.
 
  Unbundling of Network Services. Incumbent LECs must offer unbundled access
to the various elements of their network. This requirement allows new entrants
to purchase elements of an incumbent LEC's network that may be necessary to
provide service to customers not located in the new entrants' networks.
 
  Although these requirements are intended to benefit new entrants in the
local exchange market, such as the Operating Companies, it is uncertain how
effective these requirements will be until the FCC completes its rulemaking
proceeding and state regulators begin to implement the FCC's requirements. In
particular, if CLECs are unable to obtain favorable agreements with the
incumbent LEC regarding call termination and resale of incumbent LEC
facilities and services through negotiation with the incumbent LEC or
arbitration at state public utility commissions, there is a diminished
likelihood that an Operating Company will be successful in its local exchange
market.
 
  Moreover, these requirements place burdens on an Operating Company when it
provides switched local exchange services that will benefit potential
competitors. In particular, the obligation to offer services for resale means
that a company can resell the Operating Company's services without investing
in facilities. Similarly, the obligation to provide access to rights-of-way is
of limited benefit to the Operating Companies, which already have such access
through their Local Partners, but benefits other potential competitors to a
far greater degree.
 
 LEC Entry into New Markets
 
  The Company's principal competitor in each market it enters is the incumbent
LEC. See "Competition." Prior to enactment of the Telecommunications Act,
incumbent LECs generally were prohibited from providing cable television
service pursuant to the "telco/cable cross-ownership prohibition" contained in
the Communications Act of 1934. In addition, the RBOCs generally were
prohibited by the MFJ (as defined) from providing interLATA (i.e., long
distance) services within the region in which they provide local exchange
service.
 
  The Telecommunications Act repeals the telco/cable cross-ownership
prohibition and permits incumbent LECs to provide cable television service.
With this prohibition removed, incumbent LECs are more likely to invest in
fiber optic networks because those facilities will be able to generate a
revenue stream previously unavailable to the incumbent LECs. While incumbent
LEC entry into the video market may be the motivating factor for construction
of new facilities, these facilities also can be used by an incumbent LEC to
provide services that compete with the Company's networks.
 
                                      55
<PAGE>
 
  The Telecommunications Act also eliminates the prospective effect of the MFJ
and establishes procedures under which an RBOC can enter the market for
interLATA services within its telephone service area. Before an RBOC can enter
the interLATA market, it must enter into a state-approved interconnection
agreement with a company that provides local exchange service to business and
residential customers predominantly over its own facilities. Alternatively, if
no such competitor requests interconnection, the RBOC can request authority to
provide interLATA services if it offers interconnection under state-approved
terms and conditions. The interconnection offered or provided by the RBOC must
comply with a "competitive checklist" that is comparable to the
interconnection requirements discussed above. See "--Telecommunications Act of
1996--Access and Interconnection with LEC Facilities."
 
  The ability of the RBOCs to provide interLATA services enables them to
provide customers with a full range of local and long distance
telecommunications services. The provision of interLATA services by RBOCs is
expected to reduce the market share of the major long distance carriers, who
are the Company's networks' primary customers. Consequently, the entry of the
RBOCs into the long distance market may have adverse consequences on the
ability to generate revenues from the IXCs.
 
 Relaxation of Regulation
 
  A long-term goal of the Telecommunications Act is to increase competition
for telecommunications services, thereby reducing the need for regulation of
these services. To this end, the Telecommunications Act requires the FCC to
streamline its regulation of incumbent LECs and permits the FCC to forbear
from regulating particular classes of telecommunications services or
providers. Since the Company is lightly regulated by the FCC, the potential
for regulatory forbearance likely will be more beneficial to the incumbent
LECs than the Company in the long run.
 
  Pursuant to the forbearance provisions of the Telecommunications Act, the
Company has filed a petition requesting that the FCC reinstate its forbearance
policy with regard to tariff filing requirements for competitive providers of
interstate access services, such as the Company. See "--Federal Regulation."
This would relieve the Company of its biggest existing federal regulatory
burden. Furthermore, the FCC could forbear from applying interconnection
requirements to CLECs, although it is uncertain whether the FCC would consider
such action at the present time.
 
  The Telecommunications Act eliminates the requirement that LECs obtain FCC
authorization before constructing new facilities for interstate services. The
Telecommunications Act also limits the FCC's ability to review LEC tariff
filings. These changes will increase the speed with which incumbent LECs are
able to introduce new service offerings and new pricing of existing services,
thereby increasing the incumbent LECs' ability to compete with the Company.
 
 Preservation of Universal Service
 
  One of the primary goals of the original Communications Act of 1934 was to
extend telephone service to all the citizens of the United States. This goal
has been achieved largely by keeping the rates for basic local exchange
service at a reasonable level. It was traditionally thought that incumbent
LECs were able to keep basic residential rates reasonable by subsidizing them
with revenues from business and IXC customers, and by subsidizing rural
service at the expense of urban customers. The existence and level of these
subsidies has been widely disputed in recent years because they are so
difficult to quantify.
 
  The Telecommunications Act continues the goal of advancing and preserving
universal service by requiring the FCC to establish an explicit mechanism for
subsidizing service to those who might otherwise drop off the public switched
network. Although the details will be determined by the FCC, all carriers will
be required to contribute and carriers that serve eligible customers will be
able to receive subsidies. In addition, subsidies likely will be available for
companies that provide service to schools, libraries and hospitals.
 
 
                                      56
<PAGE>
 
  Depending on how the FCC implements its statutory mandate, this subsidy
mechanism may provide an additional source of revenue to those LECs willing
and able to provide service to markets that are less desirable, either because
of the high cost of providing service or the limited revenues that might be
available. This could be advantageous to the Company or it could be beneficial
to the Company's competitors, depending on the geographic areas and type of
customers for which subsidies are available. For example, if distributions are
limited to companies that provide service to residential customers, the
Company may contribute more than it receives from the universal service fund
due to its focus on business customers.
 
FEDERAL REGULATION
 
  Through a series of regulatory proceedings, the FCC has established
different levels of regulation for "dominant carriers" and "non-dominant
carriers." Only incumbent LECs are classified as dominant; all other providers
of domestic interstate services, including the Operating Companies, are
classified as non-dominant carriers. As a non-dominant carrier the Operating
Companies are subject to relatively limited regulation by the FCC. The
Operating Companies must offer interstate services at just and reasonable
rates in a manner that is not unreasonably discriminatory, subject to the
complaint provisions of the Communications Act of 1934, as amended.
 
  Presently, the Company is required to file tariffs listing the terms,
conditions and rates for its services. The FCC's policy of forbearing from
requiring non-dominant carriers to file tariffs was rejected by the U.S.
Supreme Court and its policy of permitting carriers to file tariffs listing a
range of rates for each service was rejected by the U.S. Court of Appeals for
District of Columbia Circuit. Under the Telecommunications Act, the FCC has
authority to reinstate its forbearance policy for non-dominant carriers. The
Company has filed a petition requesting the FCC to take this action with
regard to competitive providers of interstate access services, but there can
be no assurance that it will do so.
 
  The FCC has adopted rules requiring incumbent LECs to provide "virtual
collocation" to CAPs for the purpose of interconnecting their competing
networks. These rules enable the Operating Companies to carry a portion of a
customer's interstate traffic to an IXC even if the customer is not located on
the Company's network. The Company has requested collocation in some, but not
all, of its markets. The incumbent LECs have proposed interconnection rates
that are being investigated by the FCC to determine whether they are
excessive. If the FCC orders the incumbent LECs to reduce these rates,
collocation will be a more attractive option for CLECs.
 
  Under the Telecommunications Act, an Operating Company may become subject to
additional federal regulatory obligations when it provides local exchange
service in a market. All LECs, including CLECs, must make their services
available for resale by other carriers, provide nondiscriminatory access to
rights-of-way, offer reciprocal compensation for termination of traffic and
provide dialing parity and telephone number portability. In addition, the
Telecommunications Act requires all telecommunications carriers to contribute
to the universal service mechanism established by the FCC and to ensure that
their services are accessible to and usable by persons with disabilities.
 
  Because the FCC has yet to adopt rules implementing the Telecommunications
Act, it is uncertain how burdensome these requirements will be for the Company
and the Operating Companies. The obligation to provide services for resale by
others potentially limits any competitive advantage held by the Company by
virtue of its state-of-the-art facilities because other carriers, including
the incumbent LEC and the IXCs, can simply resell the Operating Companies'
services. Similarly, the obligation to provide access to rights-of-way
benefits certain competitors more than the Company, which already has such
access through its Local Partners. Most of the other obligations impose costs
on the Operating Companies that also will be borne by competing carriers so
the competitive implication of these requirements should not be significant if
they are implemented fairly by the FCC.
 
  As part of its decision requiring incumbent LECs to provide virtual
collocation, the FCC also granted incumbent LECs flexibility to reduce their
rates for interstate access services in markets where a CAP is collocated.
This flexibility includes the ability to offer volume and term discounts and
to deaverage access rates
 
                                      57
<PAGE>
 
in different "zones" in a state-based on the level of traffic. In addition,
the FCC has granted two incumbent LECs further flexibility in their most
competitive market and the FCC could grant in the future similar waivers in
markets served by the Operating Companies. The FCC also is considering
granting incumbent LECs additional pricing flexibility in its pending
proceeding regarding incumbent LEC price caps. With the passage of the
Telecommunications Act and the anticipated increase in the level of
competition faced by incumbent LECs, the FCC could grant incumbent LECs
substantial pricing flexibility with regard to interstate access services. To
the extent these regulatory initiatives enable incumbent LECs to offer
selectively reduced rates for access services, the rates the Operating
Companies for access services may charge will be constrained. The Operating
Companies' rates also will be constrained by the fact that competitors other
than the LECs are subject to the same streamlined regulatory regime as the
Operating Companies and can price their services to meet competition.
 
STATE REGULATION
 
  Most state public utility commissions require companies that wish to provide
intrastate common carrier services to be certified to provide such services.
These certifications generally require a showing that the carrier has adequate
financial, managerial and technical resources to offer the proposed services
in a manner consistent with the public interest.
 
  Operating Companies have been certificated to provide telecommunications
services in Florida, Kansas, Kentucky, New York, Pennsylvania, Tennessee,
Vermont and Virginia. The New Jersey Operating Company currently has an
application for initial operating authority pending before the New Jersey
Board of Public Utilities. The certificates in New York, Florida and Tennessee
permit the Operating Companies to provide a full range of local
telecommunications services, including basic local exchange service. In light
of the Telecommunications Act, the Operating Companies will request removal of
any restrictions that now exist on its certificates in the remaining states
and anticipate that requests will be granted. See "--Telecommunications Act of
1996--Removal of Entry Barriers." In addition, the Telecommunications Act will
enable the Company to enter new states providing a full range of local
services upon certification. In certain states, each of the Company, its
subsidiaries and the Operating Companies may be subject to additional state
regulatory requirements, including tariff filing requirements, in order to
begin offering the telecommunications services for which such entities have
been certificated. Many states also may have additional regulatory
requirements such as reporting and customer service requirements and universal
service contributions.
 
  In addition to obtaining certification, an Operating Company must negotiate
terms of interconnection with the incumbent LEC before it can begin providing
switched services. Most states in which the Company operates have not adopted
rules governing the interconnection of competing networks. Under the
Telecommunications Act, the FCC is required to adopt interconnection
requirements by August 1996. See "--Telecommunications Act of 1996--Access and
Interconnection with LEC Facilities." These rules should greatly facilitate
the negotiation of interconnection agreements, although it is anticipated that
some incumbent LECs may remain reluctant to comply with interconnection
requests, thereby delaying an Operating Company's ability to provide switched
services. State regulators are responsible for resolving any disputes that
cannot be resolved through negotiation between carriers.
 
  The Operating Companies are not presently subject to price regulation or
rate of return regulation in any state, although there can be no assurance
this will not change when the Operating Companies begin providing switched
services in some states. In most states, an Operating Company is required to
file tariffs setting forth the terms, conditions and prices for intrastate
services. In some states, an Operating Company's tariff lists a rate range or
set prices on an individual case basis.
 
  Several states have allowed incumbent LECs rate and tariff flexibility,
particularly for services deemed subject to competition. This pricing
flexibility increases the ability of the incumbent LEC to compete with an
Operating Company and constrains the rates an Operating Company may charge for
its services. In light of the additional competition that is expected to
result from the Telecommunications Act, states may grant incumbent
 
                                      58
<PAGE>
 
LECs additional pricing flexibility. At the same time, some incumbent LECs may
request increases in local exchange rates to offset revenue losses due to
competition.
 
LOCAL GOVERNMENT AUTHORIZATIONS
 
  An Operating 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, the Local Partners or
subcontractors may already possess the requisite authorizations to construct
or expand the Company's networks. An Operating Company or its Local Partners
also must obtain a license to attach facilities to utility poles in order to
build and expand facilities. Because utilities that are owned by a cooperative
or municipality are not subject to federal pole attachment regulation, there
are no assurances that an Operating Company or its Local Partners will be able
to obtain pole attachments from these utilities at reasonable rates, terms and
conditions.
 
  In some of the areas where the Operating Companies provide service, their
Local Partners pay license or franchise fees based on a percent of gross
revenue. In addition, in areas where the Company does not use facilities
constructed by a Local Partner, the Operating Company may be required to pay
such fees. 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 incumbent LECs, currently
are excused from paying license or franchise fees or pay fees that are
materially lower than those required to be paid by the Operating Company or
Local Partner. The Telecommunications 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 CLEC.
 
  If any of the existing Local Partner Agreements or Fiber Lease Agreements
held by a Local Partner or an Operating Company for a particular market were
terminated prior to its expiration date and the Local Partner or Operating
Company were 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.

                    CERTAIN RELATIONSHIPS AND TRANSACTIONS
 
  The Company was founded in October 1991. From the Company's inception
through December 31, 1995, Adelphia, which owns 89% of the Company's
outstanding common stock, provided all the equity capital to the Company and
also made loans and advances totaling approximately $49.9 million. The Company
repaid $25 million of such indebtedness to Adelphia from the proceeds of the
Offering on April 15, 1996, on which date the remaining $24.9 million,
together with accrued interest and fees of approximately $1,185,000 for the
period January 1, 1996 through April 15, 1996, was evidenced by an unsecured
subordinated note due April 16, 2003 that accrues interest at an annual rate
of 16.5% and is subordinated to the Senior Notes upon Senior Note defaults.
Interest on the subordinated note is payable quarterly in cash, through the
issuance of identical subordinated notes or in any combination thereof, at the
option of the Company. Interest (excluding fees relating to amounts borrowed)
accrued on the indebtedness to Adelphia at an annual rate of 11.3% prior to
April 15, 1996.
 
  Messrs. Drenning, Fajerski and Fowler together hold 11% of the Company's
outstanding common stock, and are parties to an amended and restated
shareholder agreement ("Shareholder Agreement") with Adelphia. The Shareholder
Agreement provides, among other things, (i) that upon the earlier of (a) the
termination of employment of any Management Shareholder or (b) after October
7, 1998, such Management Shareholder may put his shares to Adelphia for fair
market value, unless such put rights are terminated as a result of the
registration of the Company's Common Stock under the Securities Act; (ii) for
Adelphia to vote its shares in the Company to elect each Management
Shareholder to the Board of Directors of the Company; and (iii) for certain
buy/sell and termination rights and duties among Adelphia and the Management
Shareholders.
 
  The Company has also entered into Term Loan and Stock Pledge Agreements
("Loan Agreements") with each of the Management Shareholders. Pursuant to the
Loan Agreements, each Management Shareholder has borrowed $1 million from the
Company. Each of these loans accrues interest at the average rate at which the
Company can invest cash on a short-term basis, is secured by a pledge of the
borrower's common stock in the Company, and matures upon the earlier of (i)
October 8, 1998 or (ii) the date when the Company's common stock is registered
under the 1933 Act and the Management Shareholders have the right to sell
their shares pursuant to the registration rights agreement discussed below.
Each Loan Agreement also provides that any interest accruing on a loan from
the date six months after the date of such loan shall be offset by a bonus
payment which shall be paid when principal and interest thereon are due and
which shall include additional amounts to pay income taxes applicable to such
bonus payment. The Company and the Management Shareholders are also parties to
a Registration Rights Agreement that provides the Management Shareholders with
one collective demand registration right and certain piggyback registration
rights in an initial public offering of the Company's common stock.
 
  During Fiscal 1994 and Fiscal 1995 and the nine months ended December 31,
1995, the Company incurred charges from Adelphia of $214,000, $209,000 and
$250,000, respectively, for the provision to the Company of shared corporate
overhead services in areas such as personnel, payroll, management information
services, shared use of office and network facilities and support equipment.
The Company expects that charges for the provision of similar services by
Adelphia to the Company, or by the Company to Adelphia, will continue to be
incurred or charged by the Company in the future. The transactions related to
the provision of these services have been based on allocation of Adelphia's
costs incurred for these services, and do not necessarily represent the cost
to the Company had these services been provided on an arm's length basis.
During Fiscal 1995 and the nine months ended December 31, 1995, the Company
paid Adelphia or certain of Adelphia's affiliates fiber lease payments of
$303,000 and $766,000, respectively.

                          OWNERSHIP OF CAPITAL STOCK
 
  The Company previously had authorized capital consisting of 1,000 shares of
Common Stock, par value of $1.00 per share. Prior to the closing of the
Offering of the Units, the Company recapitalized (the "Recapitalization") by
(i) amending its authorized capital to consist of 30,000,000 shares of Common
Stock, par value $0.01 per share ("Common Stock") 5,000,000 shares of
Preferred Stock, par value $0.01 per share ("Preferred Stock"), and (ii)
declaring a stock split resulting in 10,000,000 shares of Common Stock being
outstanding. As of the date hereof, Adelphia owns 8,900,020 shares of Common
Stock and Messrs. Drenning, Fajerski and Fowler each own 366,660 shares of
Common Stock. In connection with the closing of the Offering of the Units, the
Company issued Warrants which will be exercisable to purchase 613,427 shares
of Common Stock at an exercise price of $0.01 per share. In addition, Adelphia
and Messrs. Drenning, Fajerski and Fowler are parties to a shareholders
agreement. See "Certain Relationships and Transactions."
 
  The following table provides information, as of May 31, 1996, with respect
to the beneficial ownership of the Company's Common Stock by (i) each person
known by the Company to be a beneficial owner of more than 5% of any class of
the Company's voting securities, (ii) the directors and executive officers and
(iii) all directors and executive officers as a group.

                        DESCRIPTION OF THE SENIOR NOTES
 
GENERAL
 
  The New Notes, like the Old Notes, will be issued pursuant to the Indenture,
dated April 15, 1996 (the "Indenture"), between the Company and Bank of
Montreal Trust Company, as trustee (the "Trustee"). The terms of the Senior
Notes include those stated in the Indenture and those made part of the
Indenture by reference
to the Trust Indenture Act of 1939 (the "Trust Indenture Act"). The terms of
the New Notes are substantially identical to the Old Notes in all material
respects (including interest rate and maturity), except that (i) the New Notes
will not be subject to the restrictions on transfer (other than with respect
to holders that are broker-dealers, persons who participated in the
distribution of the Old Notes or affiliates) and (ii) the Registration Rights
Agreement covenants regarding registration and the related Liquidated Damages
(other than those that have accrued and were not paid) with respect to
Registration Defaults will have been deemed satisfied. The Senior Notes are
subject to all such terms, and holders of Senior Notes are referred to the
Indenture and the Trust Indenture Act for a statement thereof. The following
summary of certain provisions of the Indenture does not purport to be complete
and is qualified in its entirety by reference to the Indenture, including the
definitions therein of certain terms used below. A copy of the Indenture and
Registration Rights Agreement is available as set forth under "Available
Information." The definitions of certain terms used in the following summary
are set
 
                                      63
<PAGE>
 
forth below under "--Certain Definitions." As used in this section, the term
"Company" refers only to Hyperion Telecommunications, Inc. and not to its
subsidiaries.
 
  As of the date of this Prospectus, $329,000,000 principal amount of the Old
Notes was outstanding.
 
RANKING
 
  The Senior Notes rank senior in right of payment to all subordinated
Indebtedness of the Company. The Senior Notes rank pari passu in right of
payment with all senior borrowings.
 
  The Company is the sole obligor with respect to the Senior Notes, however
the operations of the Company are conducted through its Subsidiaries and Joint
Ventures and, therefore, the Company is dependent upon the operations and cash
flow of its Subsidiaries and Joint Ventures to meet its obligations, including
its obligations under the Senior Notes. The Senior Notes are effectively
subordinated to all indebtedness and other liabilities and commitments
(including, without limitation, trade payables and lease obligations) of the
Company's Subsidiaries and Joint Ventures. Any right of the Company to receive
assets of any of its Subsidiaries and Joint Ventures upon such Subsidiary's or
Joint Venture's liquidation or reorganization (and the consequent right of the
holders of the Senior Notes to participate in those assets) is effectively
subordinated to the claims of that Subsidiary's or Joint Venture's creditors
except to the extent that the Company is itself recognized as a creditor of
such Subsidiary or Joint Venture, in which case the claims of the Company are
still subordinate to the claims of such creditors who hold any security in the
assets of such Subsidiary or Joint Venture and to the claims of such creditors
who hold indebtedness of such Subsidiary or Joint Venture senior to that held
by the Company. As of December 31, 1995, the aggregate principal amount of
such senior Indebtedness incurred by the Company's Subsidiaries and Joint
Ventures (excluding trade payables and other accrued liabilities) was
approximately $22.7 million, substantially all of which were Capital Lease
Obligations. See "Risk Factors--Holding Company Structure; Inability to Access
Cash Flow."
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Senior Notes are senior unsecured obligations of the Company, limited in
aggregate principal amount to $329.0 million at maturity and will mature on
April 15, 2003. The Senior Notes were
offered at a substantial discount from their principal amount at maturity,
along with the Warrants, to generate gross proceeds of approximately $175.3
million. See "Certain Federal Income Tax Considerations--The Senior Notes--
Original Issue Discount." Until April 15, 2001, no interest will accrue on the
Senior Notes, but the Accreted Value will accrete (representing the
amortization of original issue discount) between the date of original issuance
and April 15, 2001, on a semi-annual bond equivalent basis using a 360-day
year comprised of twelve 30-day months, such that the Accreted Value shall be
equal to the full principal amount of the Senior Notes on April 15, 2001.
Beginning on April 15, 2001, interest on the Senior Notes will accrue at a
rate of 13% per annum and will be payable semi-annually in cash on April 15
and October 15, commencing on October 15, 2001, to holders of record on the
immediately preceding April 1 and October 1. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months.
 
  Principal, premium, if any, and interest on the Senior Notes 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 may be made by check mailed to the holders of the Senior Notes at
their respective addresses set forth in the register of holders of Senior
Notes; provided that all payments with respect to Senior Notes the holders of
which have given wire transfer instructions to the Company will be required to
be made by wire transfer of same day funds to the accounts specified by the
holders thereof. Until 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. The Senior Notes are issued in denominations of $1,000 and
integral multiples thereof.

OPTIONAL REDEMPTION
 
  The Senior Notes are not be redeemable at the Company's option prior to
April 15, 2001. Thereafter, the Senior Notes 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 thereon to
the applicable redemption date, if redeemed during the twelve-month period
beginning on April 15 of the years indicated below:

      2001...........................................................   106.5%
      2002 and thereafter............................................   100.0%
</TABLE>
 
  Notwithstanding the foregoing, the Company, on or prior to April 15, 1999,
may redeem up to a maximum of 25% of the aggregate principal amount of the
Senior Notes then outstanding at a redemption price of 113.0% of the Accreted
Value thereof, with the net proceeds from either (i) an Initial Public
Offering of the common stock of the Company or (ii) a sale of the Capital
Stock (other than Disqualified Stock) of the Company to a Strategic Investor
in a single transaction or a series of related transactions for at least $25.0
million; provided that, in either case, at least 75% in aggregate principal
amount of the Senior Notes remain outstanding immediately after the occurrence
of such redemption; and provided, further, that such redemption shall occur
within 90 days of the date of the closing of such Initial Public Offering or
such sale to a Strategic Investor, as the case may be.
 
MANDATORY REDEMPTION
 
  Except as set forth below under "--Offer to Purchase upon Change of
Control," and "--Certain Covenants--Asset Sales," the Company is not required
to make mandatory redemption or sinking fund payments with respect to the
Senior Notes.
 
OFFER TO PURCHASE UPON CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Company will be required to
make an offer (the "Change of Control Offer") to each holder of Senior Notes
to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such holder's Senior Notes at a purchase price equal to 101% of
the aggregate principal amount thereof plus accrued and unpaid interest to the
date of repurchase (or, in the case of repurchases of Senior Notes prior to
April 15, 2001, at a purchase price equal to 101% of the Accreted Value
thereof as of the date of repurchase), in accordance with the procedures set
forth in the Indenture. Within ten days following any Change of Control, the
Company will mail a notice to each holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Senior Notes pursuant to the procedures required by the Indenture and
described in such notice. The Company will comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable
in connection with the repurchase of the Senior Notes as a result of a Change
of Control.
 
  The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of Control, the Indenture does not
contain provisions that permit the holders of the Senior Notes to require that
the Company repurchase or redeem the Senior Notes in the event of a takeover,
recapitalization or similar transaction.
 
  "Change of Control" means the occurrence of any of the following: (i) the
sale, lease, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all
or substantially all of the assets of the Company and its Subsidiaries taken
as a whole to any "person" (as such term is used in Section 13(d)(3) of the
Exchange Act) other than the Principals or their Affiliates, (ii) the adoption
of a plan relating to the liquidation or dissolution of the Company, (iii) the
consummation of any
 
                                      65
<PAGE>
 
transaction (including, without limitation, any merger or consolidation) the
result of which is that any "person," other than the Principals and their
Affiliates, becomes the "beneficial owner" (as such term is defined in Rule
13d-3 and Rule 13d-5 under the Exchange Act), directly or indirectly, of more
than 50% of the voting power of the Capital Stock of the Company, (iv) the
consummation of the first transaction (including, without limitation, any
merger or consolidation) the result of which is that any "person" becomes the
"beneficial owner," directly or indirectly, of more of the voting power of the
Capital Stock of the Company than is at the time "beneficially owned" by the
Principals and their Affiliates in the aggregate or (v) the first day on which
a majority of the members of the Board of Directors of the Company are not
Continuing Directors. For purposes of this definition, any transfer of an
Equity Interest of an entity that was formed for the purpose of acquiring
voting power of Capital Stock of the Company will be deemed to be a transfer
of such portion of such voting power of Capital Stock as corresponds to the
portion of the equity of such entity that has been so transferred.
 
  The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the Company's assets. Although there is a developing body of case law
interpreting the phrase "substantially all," there is no precise established
definition of the phrase under applicable law. Accordingly, the ability of a
holder of Senior Notes to require the Company to repurchase such Senior Notes
as a result of a sale, lease, transfer, conveyance or other disposition of
less than all of the assets of the Company to another person may be uncertain.
 
SELECTION AND NOTICE
 
  If fewer than all of the Senior Notes are to be redeemed at any time,
selection of Senior Notes for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities
exchange, if any, on which the Senior Notes are listed, or, if the Senior
Notes are not so listed, on a pro rata basis, by lot or by such method as the
Trustee shall deem fair and appropriate; provided that no Senior Notes of
$1,000 or less shall be redeemed in part. Notices of redemption shall be
mailed by first class mail at least 30 but not more than 60 days before the
redemption date to each holder of Senior Notes to be redeemed at its
registered address. If any Senior Note is to be redeemed in part only, the
notice of redemption that relates to such Senior Note shall state the portion
of the principal amount thereof to be redeemed. A new Senior Note in principal
amount equal to the unredeemed portion thereof will be issued in the name of
the holder thereof upon cancellation of the original Senior Note. On and after
the redemption date, interest ceases to accrue on Senior Notes or portions of
them called for redemption.
 
CERTAIN COVENANTS
 
 RESTRICTED PAYMENTS
 
  The Indenture provides that (i) the Company will not, and will not permit
any of its Subsidiaries or Joint Ventures to, directly or indirectly: (a)
declare or pay any dividend or make any other payment or distribution on
account of the Company's Equity Interests (other than dividends or
distributions payable in Equity Interests (other than Disqualified Stock) of
the Company or dividends or distributions payable to the Company or any Wholly
Owned Subsidiary); (b) purchase, redeem or otherwise acquire or retire for
value any Equity Interests of the Company or any direct or indirect parent of
the Company (other than Equity Interests owned by the Company or any Wholly
Owned Subsidiary of the Company); or (c) purchase, redeem or otherwise acquire
or retire for value, prior to a scheduled mandatory sinking fund payment date
or maturity date, any Indebtedness of the Company which ranks subordinated in
right to payment to the Senior Notes and (ii) the Company will not, and will
not permit any of its Subsidiaries or Permitted Joint Ventures to, make any
Investment other than a Permitted Investment (all such payments and other
actions set forth in clauses (i) and (ii) above being collectively referred to
as "Restricted Payments") unless, at the time of and after giving effect to
such Restricted Payment:
 
    (x) no Default or Event of Default shall have occurred and be continuing
  or would occur as a consequence thereof; and
 
                                      66
<PAGE>
 
    (y) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments (including, without limitation, all Restricted
  Payments referred to in clauses (a), (b) and (c)(1) below but excluding
  those made under clauses (c)(2) and (d) below) made by the Company and its
  Subsidiaries after the date of the Indenture is less than the sum of: (1)
  the excess of (A) Cumulative Pro Forma EBITDA over (B) 2.0 times Cumulative
  Interest Expense plus (2) the aggregate net cash proceeds received by the
  Company (other than from a Subsidiary or Joint Venture) (A) as capital
  contributions to the Company, (B) from the issuance and sale of Equity
  Interests, other than Disqualified Stock, and (C) from the issuance and
  sale of Indebtedness that is convertible into Capital Stock (other than
  Disqualified Stock), to the extent such Indebtedness is actually converted
  into such Capital Stock (clauses (A), (B) and (C) collectively referred to
  as "Equity Issuances"), other than any such net cash proceeds from Equity
  Issuances that were used as set forth in clause (c) and (d) below; and
 
    (z) the Company would, at the time of such Restricted Payment and after
  giving pro forma effect thereto as if such Restricted Payment had been made
  at the beginning of the applicable four-quarter period, have been permitted
  to incur at least $1.00 of additional Indebtedness other than Permitted
  Indebtedness.
 
  The foregoing provisions will not prohibit the following Restricted
Payments:
 
    (a) the payment of any Required Capital Contribution;
 
    (b) the payment of any dividend within 60 days after the date of
  declaration thereof, if at said date of declaration such payment would
  have complied with the provisions of the Indenture;
 
    (c) so long as no Default or Event of Default shall have occurred and be
  continuing, Restricted Joint Venture Investments, which at the time any
  such Restricted Joint Venture Investment was made, did not cause the
  aggregate amount of all Restricted Joint Venture Investments then
  outstanding under this clause (c) to exceed (1) $20.0 million plus (2) the
  net cash proceeds from Equity Issuances not used as set forth in clause
  (y) above and clause (d) below;
 
    (d) so long as no Default or Event of Default shall have occurred and be
  continuing, the making of any Investment in a Telecommunications Business
  out of the net cash proceeds from Equity Issuances not used as set forth
  in clauses (y) and (c)(2) above; or
 
    (e) so long as no Default or Event of Default shall have occurred and be
  continuing, the making of loans and advances to senior management in an
  amount not to exceed $3.0 million.
 
  For purposes of this covenant, in the event that a Restricted Joint Venture
becomes a Permitted Joint Venture or otherwise ceases to be a Restricted Joint
Venture, all of the then outstanding Investments made by such entity since the
date of the Indenture, shall be deemed to have been made as of the date that
such Restricted Joint Venture becomes a Permitted Joint Venture or otherwise
ceases to be a Restricted Joint Venture; provided that if a Restricted Joint
Venture ceases to be a Restricted Joint Venture as a result of (i) the loss of
its Local Partner or (ii) the loss of management control of such Restricted
Joint Venture, then the provisions of this paragraph shall not be applied to
such entity.
 
  The amount of all Restricted Payments, other than cash, shall be the fair
market value (evidenced by a resolution of the Board of Directors set forth in
an Officers' Certificate delivered to the Trustee) on the date of such
Restricted Payment of the asset(s) proposed to be transferred by the Company
or such Subsidiary, as the case may be, pursuant to such Restricted Payment.
Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant "Restricted Payments" were computed, which
calculations may be based upon the Company's latest available financial
statements.

<PAGE>
 
 ASSET SALES
 
  The Indenture provides that the Company will not, and will not permit any
Subsidiary to, directly or indirectly, whether in a single transaction or a
series of related transactions occurring within any twelve-month period, make
any Asset Sale, unless:
 
    (i) the Company or the Subsidiary, as the case may be, receives
  consideration at the time of such Asset Sale at least equal to the fair
  market value (as determined in good faith by the Board of Directors) for
  the shares or assets sold or otherwise disposed of; and
 
    (ii) at least 90% of such consideration consists of cash,
 
provided that
 
    (A)an amount equal to the fair market value (as determined in good faith
  by the Board of Directors) of:
 
     (1) Telecommunications Related Assets received by the Company or any
         Subsidiary from the transferee that will be used by the Company or
         such Subsidiary in the operation of a Telecommunications Business;
 
     (2) the Voting Stock of any Person engaged in a Telecommunications
         Business received by the Company or any Subsidiary; provided that
         on the date such Voting Stock is received, such Investment in
         Voting Stock constitutes a Permitted Joint Venture Investment; or
 
     (3) the publicly tradeable Voting Stock of any person engaged in the
         Telecommunications Business received by the Company or any
         Subsidiary as consideration for a sale of an Equity Interest in
         any Restricted Joint Venture, will, for the purposes of this
         covenant, be deemed to be cash which was applied in accordance
         with the first sentence of the penultimate paragraph of this
         covenant; and
 
    (B)in the case the event of a sale by (1) Hyperion Telecommunications of
  Pennsylvania, Inc., (2) Hyperion Telecommunications of Tennessee, Inc. or
  (3) Hyperion Telecommunications of New York, Inc. of its partnership
  interest in its respective partnership to its respective partner in the
  manner specified by the related partnership agreement (y) the principal
  amount of any seller note issued to the Company or any of its Wholly Owned
  Subsidiaries will be deemed to be cash for purposes of this covenant and
  (z) the payments of principal pursuant to such seller note shall be deemed
  to be Net Cash Proceeds (for purposes of the penultimate paragraph of this
  covenant) as and when such payments are received.
 
  For purposes of this covenant, the first $1.0 million of Net Cash Proceeds
received from Asset Sales in any fiscal year shall not be subject to the
restrictions contained in this covenant.
 
  The Indenture provides that, in determining the fair market value with
respect to any Asset Sale or series of related Asset Sales involving aggregate
consideration in excess of $10.0 million, the Board of Directors of the
Company must obtain an opinion as to the fairness to the holders of the Senior
Notes of such Asset Sales from a financial point of view issued by a
nationally recognized investment banking firm with total assets in excess of
$1.0 billion; provided that no such opinion is required if such Asset Sale is
in accordance with the terms of any Local Partnership Agreement to which the
Company or any of its Subsidiaries is a party on the date of the Indenture.
 
  The Indenture also provides that the Company may apply the Net Cash Proceeds
from such Asset Sale to an investment in Telecommunications Related Assets in
a Telecommunications Service Market within 180 days after any Asset Sale;
provided that if the Company determines to make such investment in a New
Telecommunications Service Market, the Company will (y) within 180 days of
such Asset Sale, deliver to the
 
                                      68
<PAGE>
 
Trustee a resolution adopted by a majority of the Board of Directors set forth
in an Officer's Certificate certifying that the Company intends to utilize the
Net Cash Proceeds of such Asset Sale to invest in a specific new
Telecommunications Service Market and (z) complete such investment within 360
days of such Asset Sale. The Company will be deemed to have completed its
investment for purposes of the preceding clause (z), so long as the Company
has (i) a business plan that sets forth the Company's investment plans for the
applicable Telecommunications Service Market and (ii) issued all material
purchase orders to the appropriate parties that are necessary to complete such
business plan. Any Net Cash Proceeds from an Asset Sale that are not invested
as provided in the preceding sentence shall constitute Excess Proceeds. When
the aggregate amount of Excess Proceeds exceeds $2.5 million, the Company
shall offer to purchase (an "Asset Sale Offer") from all holders of the Senior
Notes the maximum principal amount of Senior Notes that may be purchased out
of the Excess Proceeds, at an offer price in cash equal to 100% of aggregate
principal amount thereof, plus accrued and unpaid interest to the date of
repurchase (or, in the case of repurchases of Senior Notes prior to April 15,
2001, at a purchase price equal to 100% of the Accreted Value thereof as of
the date of repurchase) in accordance with the procedures set forth in the
Indenture. To the extent that the aggregate principal amount thereof, plus
accrued and unpaid interest to the date of repurchase (or, in the case of
repurchases of Senior Notes prior to April 15, 2001, the Accreted Value
thereof as of the date of repurchase) of the Senior Notes tendered pursuant to
an Asset Sale Offer is less than the Excess Proceeds, the Company may use such
remaining Excess Proceeds for any purpose not prohibited by the Indenture. If
the aggregate principal amount thereof, plus accrued and unpaid interest to
the date of repurchase (or, in the case of repurchases of Senior Notes prior
to April 15, 2001, the Accreted Value thereof as of the date of repurchase) of
Senior Notes surrendered by holders thereof exceeds the amount of Excess
Proceeds, the Company shall select the Senior Notes to be purchased on a pro
rata basis. Upon completion of such offer, the amount of Excess Proceeds shall
be reset at zero. Pending application of the Net Cash Proceeds as set forth
above from Asset Sales, all such Net Cash Proceeds will be placed in escrow
for the benefit of the holders of the Senior Notes. The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Senior
Notes as a result of an Asset Sale.
 
  Notwithstanding the foregoing, the Company will not, and will not permit any
Subsidiary to, directly or indirectly, make any Asset Sale of any Equity
Interests of any Subsidiary (at least 80% of the voting power of the Capital
Stock of which is owned by the Company) except pursuant to an Asset Sale of
all of the Equity Interests of such Subsidiary; provided that any sale of any
Equity Interest of any such Subsidiary to a Strategic Investor shall be deemed
not to be an Asset Sale for purposes of this covenant, so long as such sale of
such Equity Interests does not result in such Subsidiary ceasing to be a
Subsidiary of the Company.
 
 INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries or Joint Ventures to, directly or indirectly, create, incur,
issue, assume, guaranty or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including, without limitation, Acquired Indebtedness) and that
the Company will not issue any Disqualified Stock and will not permit any of
its Subsidiaries or Joint Ventures to issue any shares of Preferred Stock;
provided that the Company may incur Indebtedness (including Acquired
Indebtedness) or issue shares of Disqualified Stock if the Company's
Consolidated Leverage Ratio as of the last day of the Company's most recently
ended fiscal quarter for which internal financial statements are available
immediately preceding the date on which such Indebtedness is incurred, or such
Disqualified Stock is issued, as the case may be, would have been (a) greater
than zero and less than 5.5 to 1.0, if such incurrence or issuance is on or
prior to March 31, 1999, and (b) greater than zero and less than 5.0 to 1.0,
if such incurrence or issuance is after March 31, 1999, determined on a pro
forma basis (including pro forma application of the net proceeds therefrom) as
if such Indebtedness had been incurred, or such Disqualified Stock had been
issued, as the case may be, at the beginning of such fiscal quarter.
 
  The foregoing provisions do not apply to:
 
 
                                      69
<PAGE>
 
    (i) the incurrence of Indebtedness by the Company, any Subsidiary (other
  than a General Partner Subsidiary) or any Permitted Joint Venture pursuant
  to Credit Agreement(s), provided that the aggregate principal amount of
  such Credit Agreement(s) at any one time outstanding under this clause (i)
  does not exceed $50.0 million for the Company, all of its Subsidiaries
  (other than a General Partner Subsidiary) and all of its Permitted Joint
  Ventures combined;
 
    (ii) the incurrence of Vendor Debt by the Company, any Subsidiary (other
  than a General Partner Subsidiary) or any Permitted Joint Venture, provided
  that the aggregate principal amount of such Vendor Debt does not exceed 80%
  of the purchase price or cost of the construction, acquisition or
  improvement of the applicable Telecommunications Related Assets;
 
    (iii) Refinancing Indebtedness;
 
    (iv) the incurrence of Indebtedness by the Company not to exceed, at any
  one time outstanding, 2.0 times the net cash proceeds received by the
  Company from the issuance and sale of its Capital Stock (other than
  Disqualified Stock) to a Person other than a Subsidiary or a Joint Venture
  of the Company, provided that such Indebtedness (y) does not mature prior
  to the Stated Maturity of the Senior Notes and has a Weighted Average Life
  to Maturity longer than the Senior Notes and (z) is subordinated to the
  Senior Notes;
 
    (v) the incurrence by the Company of Indebtedness (in addition to
  Indebtedness permitted by any other clause of this paragraph) in an
  aggregate principal amount (or accreted value, as applicable) at any time
  outstanding not to exceed $10.0 million;
 
    (vi) the incurrence by any Restricted Joint Venture of Non-Recourse Debt,
  provided that if any Non-Recourse Debt of a Restricted Joint Venture ceases
  to be Non-Recourse Debt, such event shall be deemed to constitute an
  incurrence of Indebtedness as of the date such Indebtedness ceases to be
  Non-Recourse Debt; and
 
    (vii) the guarantee of Indebtedness by a General Partner Subsidiary in
  connection with the incurrence of Indebtedness by the Restricted Joint
  Venture of which such General Partner Subsidiary is a general partner.
 
  For purposes of this covenant, the Indenture provides that, in the event
that the Company proposes to incur Indebtedness pursuant to clause (iv) above,
the Company shall, simultaneously with the incurrence of such Indebtedness,
deliver to the Trustee a resolution of the Board of Directors set forth in an
Officers' Certificate stating that the sale or sales of Capital Stock forming
the basis for the incurrence of such Indebtedness (i) constitutes a long term
investment in the Company and (ii) has not been made for the purpose of
circumventing this covenant. The Indenture also provides that, in event that
the Company rescinds, reverses or unwinds such sale of Capital Stock or
otherwise returns or refunds all or any portion of the net cash proceeds of
such sale of Capital Stock (whether by dividend, distribution or otherwise)
within 270 days of the date of the incurrence of such Indebtedness, such
Indebtedness will be deemed to be incurred on the date of, and immediately
after giving effect to, such rescission, reversal, unwinding, return or
refund.
 
  For purposes of this covenant, in the event that a Restricted Joint Venture
becomes a Permitted Joint Venture or otherwise ceases to be a Restricted Joint
Venture, all of the then outstanding Indebtedness of such entity shall be
deemed to have been incurred as of the date that such Restricted Joint Venture
becomes a Permitted Joint Venture or otherwise ceases to be a Restricted Joint
Venture.
 
  In addition to the foregoing provisions, the Indenture permits the Company's
Subsidiaries (other than General Partner Subsidiaries) and Permitted Joint
Ventures to incur Indebtedness (including Acquired Debt) all of the net
proceeds of which are used by such Subsidiary or Permitted Joint Venture
directly in connection with the design, construction, development or
acquisition of a Telecommunications Service Market if, as of the last day of
the Company's most recently ended fiscal quarter for which internal financial
statements are available
 
                                      70
<PAGE>
 
immediately preceding the date on which such Indebtedness is incurred, either
(a) the aggregate principal amount of all Indebtedness of such Subsidiary or
such Permitted Joint Venture does not exceed 1.75 times the Invested Equity
Capital of such Subsidiary or such Permitted Joint Venture; or (b) the
Consolidated Leverage Ratio of such Subsidiary or such Permitted Joint Venture
would not have been greater than 3.5 to 1.0, in each case determined on a pro
forma basis (including pro forma application of the net proceeds therefrom) as
if such Indebtedness had been incurred at the beginning of such fiscal
quarter; provided that any Indebtedness incurred by any Subsidiary of the
Company or any Permitted Joint Venture (other than Related Networks) pursuant
to this paragraph shall be non-recourse with respect to the Company or any
other Subsidiary of the Company or any other Joint Venture.
 
 LIENS
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries or Permitted Joint Ventures to, directly or indirectly,
create, incur, assume or suffer to exist any Lien on any asset now owned or
hereafter acquired, or any income or profits therefrom or assign or convey any
right to receive income therefrom, except Permitted Liens.
 
 LIMITATIONS ON SALE AND LEASEBACK TRANSACTIONS
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, enter into any Sale and Leaseback Transaction; provided
that the Company or any Subsidiary (other than a General Partner Subsidiary)
may enter into a Sale and Leaseback Transaction if (i) the Company or other
entity could have incurred the Indebtedness relating to such Sale and
Leaseback Transaction pursuant to the "--Incurrence of Indebtedness and
Issuance of Preferred Stock" and "--Liens" covenants to incur secured
Indebtedness in an amount equal to the Attributable Debt with respect to such
transaction, (ii) the net proceeds of such Sale and Leaseback Transaction are
at least equal to the fair market value of such property as determined in good
faith by the Board of Directors of the Company and (iii) such proceeds are
applied in accordance with the "--Asset Sales" covenant.
 
 DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any encumbrance or restriction on the
ability of any Subsidiary to:
 
    (i)(a) pay dividends or make any other distributions to the Company or
  any of its Subsidiaries (1) on its Capital Stock or (2) with respect to any
  other interest or participation in, or measured by, its profits, or (b) pay
  any indebtedness owed to the Company or any of its Subsidiaries,
 
    (ii) make loans or advances to the Company or any of its Subsidiaries,
 
    (iii) grant liens or grant security interests on its asset in favor of
  the holders of the Senior Notes or guarantee the payment of the Senior
  Notes; or
 
    (iv) transfer any of its properties or assets to the Company or any of
  its Subsidiaries,
 
except for such encumbrances or restrictions existing under or by reason of:
 
      (a) Existing Indebtedness as in effect on the date of the Indenture;
 
      (b) any Credit Agreement creating or evidencing Indebtedness
    permitted by the Indenture and any amendments, modifications,
    restatements, renewals, increases, supplements, refundings,
    replacements or refinancings thereof;
 
 
                                      71
<PAGE>
 
      (c) the Indenture and the Senior Notes;
 
      (d) applicable law;
 
      (e) by reason of customary non-assignment provisions in leases
    entered into in the ordinary course of business and consistent with
    past practices;
 
      (f) purchase money obligations or Vendor Debt for property acquired
    in the ordinary course of business that impose restrictions of the
    nature described in clause (iv) above on the property so acquired;
 
      (g) Indebtedness incurred pursuant to the last paragraph under the
    "--Incurrence of Indebtedness and Issuance of Preferred Stock"
    covenant, provided that such encumbrance or restriction only relates to
    the Subsidiary or Permitted Joint Venture incurring such Indebtedness;
    and
 
      (h) Refinancing Indebtedness, provided that such encumbrances or
    restrictions are no more restrictive than those contained in the
    documentation governing the Indebtedness being extended, refinanced,
    renewed, replaced, defeased or refunded.
 
 MERGER, CONSOLIDATION OR SALE OF ASSETS
 
  The Indenture provides that the Company may not consolidate or merge with or
into (whether or not the Company is the surviving corporation), 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
corporation or the entity or the 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 shall have been
made is a corporation organized or existing under the laws of the United
States, any state thereof or the District of Columbia; (ii) the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company under the Senior Notes and the Indenture pursuant
to a supplemental indenture in a form reasonably satisfactory to the Trustee;
(iii) immediately after such transaction no Default or Event of Default
exists; and (iv) except in the case of a merger of the Company with or into a
Wholly Owned Subsidiary of the Company, the Company 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 shall have been made (A) will have Consolidated Net Worth
immediately after the transaction equal to or greater than the Consolidated
Net Worth of the Company immediately preceding the transaction and (B) will,
at the time of such transaction and after giving pro forma effect thereto as
if such transaction had occurred at the beginning of the applicable four-
quarter period, be permitted to incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) pursuant to the "--Incurrence
of Indebtedness and Issuance of Preferred Stock" covenant contained herein.
 
 TRANSACTIONS WITH AFFILIATES
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any 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, other than those that would have
  been obtained in a comparable transaction by the Company or such Subsidiary
  with an unrelated Person; and
 
 
                                      72
<PAGE>
 
    (ii) the Company delivers to the Trustee (a) with respect to any
  Affiliate Transaction or series of related Affiliate Transactions involving
  aggregate consideration in excess of $1.0 million, a resolution adopted by
  a majority of the disinterested members of the Board of Directors and a
  majority of the Independent Directors of the Company set forth in an
  Officers' Certificate certifying that such Affiliate Transaction complies
  with clause (i) above; and (b) with respect to any Affiliate Transaction or
  series of related Affiliate Transactions involving aggregate consideration
  in excess of $10.0 million, an opinion as to the fairness to the holders of
  the Senior Notes of such Affiliate Transaction from a financial point of
  view issued by a nationally recognized consulting firm, business valuation
  firm or investment banking firm;
 
provided that: (i) all agreements and arrangements with Affiliates, including
without limitation the Local Partner Agreements, the Fiber Lease Agreements,
the Management Agreements, network monitoring agreements and transactions in
connection therewith or pursuant thereto existing on the date of the Indenture
and through the current term thereof; (ii) all arrangements and transactions
with Adelphia, including existing intercompany Indebtedness, overhead charges
made in the ordinary course of business, fiber lease arrangements and similar
services existing on the date of the Indenture and through the current term
thereof; (iii) all employment arrangements approved by the Board of Directors;
(iv) all Restricted Payments made pursuant to the covenant entitled "--
Restricted Payments;" (v) transactions between or among the Company and/or its
Wholly Owned Subsidiaries; (vi) transactions between a General Partner
Subsidiary and the Restricted Joint Venture of which such General Partner
Subsidiary is a general partner; and (vii) management and network monitoring
agreements between the Company and any of its Joint Ventures, shall not be
deemed Affiliate Transactions.
 
 LOANS TO SUBSIDIARIES AND JOINT VENTURES
 
  The Indenture provides that all loans to Subsidiaries or Joint Ventures made
by the Company from time to time after the date of the Indenture will be
evidenced by Intercompany Notes in favor of the Company. The Indenture also
provides that all loans by the Company to any Subsidiary or Joint Venture
outstanding on the date of the Indenture will be evidenced by an unsecured
Intercompany Note. The Indenture prohibits loans by Subsidiaries to other
Subsidiaries and prohibits loans by Subsidiaries to Joint Ventures in which
such Subsidiary does not have an Equity Interest, except that such loans may
be (i) incurred and maintained between and among the Company, its Subsidiaries
and Permitted Joint Ventures in connection with the incurrence of Indebtedness
pursuant to clause (i) of the covenant entitled "--Incurrence of Indebtedness
and Issuance of Preferred Stock" or (ii) incurred and maintained between and
among Related Networks in connection with the incurrence of Indebtedness by
such Related Networks pursuant to the proviso in the last paragraph of the
covenant entitled "--Incurrence of Indebtedness and Issuance of Preferred
Stock." A form of Intercompany Note is attached as an annex to the Indenture.
 
 LIMITATION ON STATUS AS INVESTMENT COMPANY
 
  The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, conduct its business in a fashion that would cause it to
be required to register as an "investment company" (as that term is defined in
the Investment Company Act of 1940, as amended) or otherwise become subject to
regulation under the Investment Company Act of 1940.
 
 PAYMENTS FOR CONSENT
 
  The Indenture provides that neither the Company nor any of its Subsidiaries
shall, directly or indirectly, pay or cause to be paid any consideration,
whether by way of interest, fee or otherwise, to any holder of any Senior
Notes for or as inducement to any consent, waiver or amendment of any terms or
provisions or the Senior Notes unless such consideration is offered to be paid
or agreed to be paid to all holders of the Senior Notes which so consent,
waive or agree to amend in the time frame set forth in solicitation documents
relating to such consent, waiver or agreement.
 
 
                                      73
<PAGE>
 
INDEPENDENT DIRECTORS
 
  The Company is required, no later than 360 days from the date of the
Indenture, to have at least two members of its Board of Directors who are
neither officers nor employees of the Company or its Affiliates (the
"Independent Directors"). Any transaction requiring the approval of the
majority of the Independent Directors shall be prohibited at any time that
there are not at least two Independent Directors on the Company's Board of
Directors. If Hyperion fails to comply with this covenant, Hyperion will pay
Liquidated Damages to each holder of Senior Notes (i) with respect to the
first 90-day period immediately following the occurrence of such default at a
rate of 0.5% per annum, determined daily, on the Accreted Value of the Senior
Notes (or after April 15, 2001, on the principal amount of the Senior Notes)
and (ii) at the beginning of each subsequent 90-day period at a rate increased
by an additional 0.25% per annum up to a maximum aggregate increase of 2.0%
per annum until such default has been cured.
 
 BUSINESS ACTIVITIES
 
  The Company will not, and will not permit any Subsidiary to, engage in any
business other than the Telecommunications Business and such business
activities as are incidental or related thereto.
 
 REPORTS
 
  The Indenture provides that, whether or not required by the rules and
regulations of the Securities and Exchange Commission (the "Commission"), so
long as any Senior Notes are outstanding, the Company is required to furnish
to the holders of Senior Notes (i) all quarterly and annual financial
information that would be required to be contained in a filing with the
Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and, with respect to the annual
information only, a report thereon by the Company's certified independent
accountants; (ii) all current reports that would be required to be filed with
the Commission on Form 8-K if the Company were required to file such reports;
and (iii) on a quarterly basis, certain financial information and operating
data with respect to each Subsidiary and Joint Venture engaged in a
Telecommunications Business, in the form specified by Schedule E of the
Indenture. In addition, whether or not required by the rules and regulations
of the Commission, the Company is required to file a copy of all such
information and reports with the Commission for public availability (unless
the Commission will not accept such a filing) and make such information
available to securities analysts and prospective investors upon request. In
addition, the Company has agreed that, for so long as any Senior Notes 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.
 
EVENTS OF DEFAULT AND REMEDIES
 
  The Indenture provides that each of the following constitutes an Event of
Default:
 
    (i) default for 30 days in the payment when due of interest on the Senior
  Notes;
 
    (ii) default in payment when due of the principal of or premium, if any,
  on the Senior Notes;
 
    (iii) failure by the Company to comply with the provisions described
  under the captions "--Change of Control," "--Asset Sales," "--Restricted
  Payments," or "--Merger, Consolidation or Sale of Assets";
 
    (iv) failure by the Company to comply with the provisions described under
  the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock,"
  provided that for purposes of the penultimate paragraph of such covenant,
  in the event that the Company fails to comply with such covenant because
  indebtedness is deemed to be incurred by a Restricted Joint Venture solely
  as a result of such Restricted Joint Venture ceasing to be a Restricted
  Joint Venture as a result of (i) the loss of a Local Partner or (ii) the
  loss of management control of such Restricted Joint Venture, such failure
  shall continue for 90 days;
 
                                      74
<PAGE>
 
    (v) failure by the Company for 30 days after notice to comply with any of
  its other agreements in the Indenture or the Senior Notes;
 
    (vi) 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 date of the Indenture, which default (a) is caused by a
  failure to pay principal of or premium, if any, or interest on such
  Indebtedness prior to the expiration of the grace period provided in such
  Indebtedness on the date of such default (a "Payment Default") or (b)
  results in the acceleration of such Indebtedness prior to its express
  maturity and, in each case, the principal amount of any such Indebtedness,
  together with the principal amount of any other such Indebtedness under
  which there has been a Payment Default or the maturity of which has been so
  accelerated, aggregates $5.0 million or more;
 
    (vii) failure by the Company or any of its Subsidiaries to pay final
  judgments aggregating in excess of $5.0 million, which judgments are not
  paid within, discharged by or stayed for a period of 60 days;
 
    (viii) certain events of bankruptcy or insolvency with respect to the
  Company or any of its Significant Subsidiaries or any of its Joint Ventures
  that would, if it were a Subsidiary, constitute a Significant Subsidiary.
 
  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 Senior Notes may
declare all the Senior Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Company, any
Significant Subsidiary or any group of Subsidiaries that, taken together,
would constitute a Significant Subsidiary, all outstanding Senior Notes will
become due and payable without further action or notice. Holders of the Senior
Notes may not enforce the Indenture or the Senior Notes except as provided in
the Indenture. Subject to certain limitations, holders of a majority in
principal amount of the then outstanding Senior Notes may direct the Trustee
in its exercise of any trust or power. The Trustee may withhold from holders
of the Senior Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal or
interest) if it determines that withholding notice is in their interest.
 
  In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the 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 Senior Notes pursuant
to the optional redemption provisions of the Indenture, an equivalent premium
shall also become and be immediately due and payable to the extent permitted
by law upon the acceleration of the Senior Notes. If an Event of Default
occurs prior to April 15, 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 Senior Notes prior to April 15,
2001, then the premium specified in the Indenture shall also become
immediately due and payable to the extent permitted by law upon the
acceleration of the Senior Notes.
 
  The holders of a majority in aggregate principal amount of the Senior Notes
then outstanding by notice to the Trustee may on behalf of the holders of all
of the Senior Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Senior Notes.
 
  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.

NO PERSONAL LIABILITY 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
Senior Notes or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each holder of Senior Notes by
accepting a Senior Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Senior Notes. Such
waiver may not be effective to waive liabilities under the federal securities
laws and it is the view of the Commission that such a waiver is against public
policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Senior Notes ("Legal
Defeasance") except for:
 
    (i) the rights of holders of outstanding Senior Notes to receive payments
  in respect of the principal of, premium, if any, and interest on such
  Senior Notes when such payments are due from the trust referred to below;
 
    (ii) the Company's obligations with respect to the Senior Notes
  concerning issuing temporary Senior Notes, registration of Senior Notes,
  mutilated, destroyed, lost or stolen Senior Notes and the maintenance of an
  office or agency for payment and money for security payments held in trust;
 
    (iii) the rights, powers, trusts, duties and immunities of the Trustee,
  and the Company's obligations in connection therewith; and
 
    (iv) the Legal Defeasance provisions of the Indenture.
 
In addition, the Company may, at its option and at any time, elect to have the
obligations of the Company released with respect to certain covenants that are
described in the Indenture ("Covenant Defeasance") and thereafter any omission
to comply with such obligations shall not constitute a Default or Event of
Default with respect to the Senior Notes. In the event Covenant Defeasance
occurs, certain events (not including non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Senior Notes.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance:
 
    (i) the Company must irrevocably deposit with the Trustee, in trust, for
  the benefit of the holders of the Senior Notes, cash in U.S. dollars, non-
  callable Government Securities, or a combination thereof, in such amounts
  as will be sufficient, in the opinion of a nationally recognized firm of
  independent public accountants, to pay the principal of, premium, if any,
  and interest on the outstanding Senior Notes on the stated maturity or on
  the applicable redemption date, as the case may be, and the Company must
  specify whether the Senior Notes are being defeased to maturity or to a
  particular redemption date;
 
    (ii) in the case of Legal Defeasance, the Company shall have delivered to
  the Trustee an opinion of counsel in the United States reasonably

required to transfer or exchange any Senior Note for a period of 15 days
before a selection of Senior Notes to be redeemed.
 
  The registered holder of a Senior Note will be treated as the owner of it

AMENDMENT, SUPPLEMENT AND WAIVER
 
  Except as provided in the next three succeeding paragraphs, the Indenture or
the Senior Notes may be amended or supplemented with the consent of the
holders of at least a majority in aggregate outstanding principal amount of
the Senior Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Senior
Notes), and any existing default or compliance with any provision of the
Indenture or the Senior Notes may be waived with the consent of the holders of
a majority in principal amount of the then outstanding Senior Notes (including
consents obtained in connection with a tender offer or exchange offer for
Senior Notes).
 
  Without the consent of each holder affected, an amendment or waiver may not
(with respect to any Senior Notes held by a non-consenting holder):
 
    (i) reduce the principal amount of Senior Notes whose holders must
  consent to an amendment, supplement or waiver;
 
 
                                      77
<PAGE>
 
    (ii) reduce the principal of or change the fixed maturity of any Senior
  Note or alter the provisions with respect to the redemption of the Senior
  Notes (other than provisions relating to the covenants described above
  under the caption "--Offer to Purchase Upon Change of Control" and "--Asset
  Sales");
 
    (iii) reduce the rate of or change the time for payment of interest on
  any Senior Note;

  default that resulted from such acceleration);
 
    (v) make any Senior Note payable in money other than that stated in the
  Senior Notes;

  than a payment required by the covenants described above under the captions

  Sales"); and
 
    (viii) make any change in the foregoing amendment and waiver provisions.
 
  Notwithstanding the foregoing, without the consent of any holder of Senior
Notes, the Company and the Trustee may amend or supplement the Indenture or
the Senior Notes to cure any ambiguity, defect or inconsistency, to provide
for uncertificated Senior Notes in addition to or in place of certificated
Senior Notes, to provide for the assumption of the Company's obligations to
holders of Senior Notes in the case of a merger or consolidation, to make any
change that would provide any additional rights or benefits to the holders of
Senior Notes or that does not adversely affect the legal rights under the
Indenture of any such holder, or to comply with requirements of the Commission
in order to effect or maintain the qualification of the Indenture under the
Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
  The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage
in other transactions; however, if it acquires any conflicting interest it
must eliminate such conflict within 90 days, apply to the Commission for
permission to continue or resign. The Trustee also serves as Registrar and
Paying Agent and Trustee under certain indentures governing debt securities of
Adelphia.
 
  The holders of a majority in principal amount of the then outstanding Senior
Notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the
Indenture at the request of any holder of Senior Notes, unless such holder
shall have offered to the Trustee security and indemnity satisfactory to it
against any loss, liability or expense.
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
  The Company and the Initial Purchasers entered into the Registration Rights
Agreement pursuant to which the Company agreed to file the Exchange Offer
Registration Statement with the Commission. If (i) the Company
 
                                      78
<PAGE>
 
is not required to file the Exchange Offer Registration Statement or permitted
to consummate the Exchange Offer because the Exchange Offer is not permitted
by applicable law or Commission policy or (ii) any holder of Transfer
Restricted Securities notifies the Company within the specified time period
that (A) it is prohibited by law or Commission policy from participating in
the Exchange Offer or (B) that it may not resell the New Notes acquired by it
in the Exchange Offer to the public without delivering a prospectus and the
prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales or (C) that it is a broker-dealer
and owns Senior Notes acquired directly from the Company or an affiliate of
the Company, the Company will file with the Commission a Shelf Registration
Statement to cover resales of the Senior Notes by the holders thereof who
satisfy certain conditions relating to the provision of information in
connection with the Shelf Registration Statement. The Company will use its
best efforts to cause the applicable registration statement to be declared
effective as promptly as possible by the Commission. For purposes of the
foregoing, "Transfer Restricted Securities" means each Old Note until (i) the
date on which such Old Note has been exchanged by a person other than a
broker-dealer for a New Note in the Exchange Offer, (ii) following the
exchange by a broker-dealer in the Exchange Offer of an Old Note for a New
Note, the date on which such New Note is sold to a purchaser who receives from
such broker-dealer on or prior to the date of such sale a copy of the
prospectus contained in the Exchange Offer Registration Statement, (iii) the
date on which such Old Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Senior Note is distributed to the
public pursuant to Rule 144 under the Act.
 
  The Registration Rights Agreement provides that (i) the Company will use its
best efforts to have the Exchange Offer Registration Statement declared
effective by the Commission on or prior to October 12, 1996, (ii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Company will commence the Exchange Offer and use its best efforts to
issue, on or prior to 30 business days after the date on which the Exchange
Offer Registration Statement was declared effective by the Commission, New
Notes in exchange for all Old Notes tendered prior thereto in the Exchange
Offer and (iii) if obligated to file the Shelf Registration Statement, the
Company will use its best efforts to file the Shelf Registration Statement
with the Commission on or prior to 30 days after such filing obligation arises
(and in any event by October 12, 1996) and to cause the Shelf Registration to
be declared effective by the Commission on or prior to 30 days after such
obligation arises. If (a) the Company fails to file any of the Registration
Statements required by the Registration Rights Agreement on or before the date
specified for such filing, (b) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for
such effectiveness (the "Effectiveness Target Date"), (c) the Company fails to
Consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement or (d)
the Shelf Registration Statement or the Exchange Offer Registration Statement
is declared effective but thereafter ceases to be effective or usable in
connection with resales of Transfer Restricted Securities during the periods
specified in the Registration Rights Agreement (each such event referred to in
clauses (a) through (d) above a "Registration Default"), then the Company must
pay Liquidated Damages to each holder of Transfer Restricted Securities, with
respect to the first 90-day period immediately following the occurrence of
such Registration Default, at a rate of 0.5% per annum, determined daily, on
the Accreted Value of the Senior Notes (or after April 15, 2001, on the
principal amount of the Senior Notes) as of the immediately preceding interest
payment date. Such interest rate will increase by an additional 0.25% per
annum at the beginning of each subsequent 90-day period up to a maximum
aggregate increase of 2.0% per annum until all Registration Defaults have been
cured, at which time the accrual rate borne by the Senior Notes will be
reduced to the original accrual rate. All accrued Liquidated Damages will be
paid by the Company on each Damages Payment Date to the Global Senior Note
holder by wire transfer of immediately available funds or by federal funds
check and to holders of Certificated Securities by mailing checks to their
registered addresses.
 
  Holders of Old Notes are required to make certain representations to the
Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and are required to deliver information to
be used in connection with the Shelf Registration Statement and to provide
comments on the Shelf

BOOK-ENTRY, DELIVERY AND FORM
 
  Except as set forth in the next paragraph, the New Notes will initially be
issued in the form of one or more registered notes in global form (the "New
Global Note," and together with the global notes representing the Old Notes,
the "Global Note"). The New Global Note will be deposited on the Exchange Date
with, or on behalf of, the Depositary and registered in the name of the Global
Note Holder.
 
  New Notes that were issued as described below under "Certificated
Securities" will be issued in the form of registered definitive certificates
(the "Series B Certificated Securities"). Upon the transfer to a qualified
institutional buyer of Certificated Securities initially issued to a purchaser
of the Units who does not hold its interest in the Units, the Senior Notes and
the Warrants (a "Non-Global Purchaser"), such Certificated Securities
 
                                      90
<PAGE>
 
may, unless the Global Note has previously been exchanged for Certificated
Securities, be exchanged for an interest in the Global Note representing the
amount of the Senior Notes being transferred.
 
  The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the
"Participants" or the "Depositary's Participants") and to facilitate the
clearance and settlement of transactions in such securities between
Participants through electronic book-entry changes in accounts of its
Participants. The Depositary's Participants include securities brokers and
dealers, banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively,
the "Indirect Participants" or the "Depositary's Indirect Participants") that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly. Persons who are not Participants may beneficially own
securities held by or on behalf of the Depositary only through the
Depositary's Participants or the Depositary's Indirect Participants.
 
  The Company expects that pursuant to procedures established by the
Depositary ownership of the Senior Notes evidenced by the Global Note will be
shown on, and the transfer of ownership thereof will be effected only through,
records maintained by the Depositary (with respect to the interests of the
Depositary's Participants), the Depositary's Participants and the Depositary's
Indirect Participants. Holders are advised that the laws of some states
require that certain persons take physical delivery in definitive form of
securities that they own. Consequently, the ability to transfer Senior Notes
evidenced by the Global Note will be limited to such extent.
 
  So long as the Global Note Holder is the registered owner of any Senior
Notes, the Global Note Holder will be considered the sole Holder under the
Indenture of any Senior Notes evidenced by the Global Note. Beneficial owners
of Senior Notes evidenced by the Global Note will not be considered the owners
or Holders thereof under the Indenture for any purpose, including with respect
to the giving of any directions, instructions or approvals to the Trustee
thereunder. Neither the Company nor the Trustee will have any responsibility
or liability for any aspect of the records of the Depositary or for
maintaining, supervising or reviewing any records of the Depositary relating
to the Senior Notes.
 
  Payments in respect of the principal of, premium, if any, interest and
Liquidation Damages, if any, on any Senior Notes registered in the name of the
Global Note Holder on the applicable record date will be payable by the
Trustee to or at the direction of the Global Note Holder in its capacity as
the registered Holder under the Indenture. Under the terms of the Indenture,
the Company and the Trustee may treat the Persons in whose names Senior Notes,
including the Global Note, are registered as the owners thereof for the
purpose of receiving such payments. Consequently, neither the Company nor the
Trustee has or will have any responsibility or liability for the payment of
such amounts to beneficial owners of Senior Notes (including principal,
premium, if any, interest and Liquidation Damages, if any). The Company
believes, however, that it is currently the policy of the Depositary to
immediately credit the accounts of the relevant Participants with such
payments, in amounts proportionate to their respective holdings of beneficial
interests in the relevant security as shown on the records of the Depositary.
Payments by the Depositary's Participants and the Depositary's Indirect
Participants to the beneficial owners of Senior Notes will be governed by
standing instructions and customary practice and will be the responsibility of
the Depositary's Participants or the Depositary's Indirect Participants.
 
CERTIFICATED SECURITIES
 
  Subject to certain conditions, any Person having a beneficial interest in
the Global Note may, upon request to the Trustee, exchange such beneficial
interest for Senior Notes in the form of Certificated Securities. Upon any
such issuance, the Trustee is required to register such Certificated
Securities in the name of, and cause the same to be delivered to, such Person
or Persons (or the nominee of any thereof). If (i) the Company notifies the
Trustee 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 Trustee in writing
that it elects to cause the issuance of Senior Notes in the form of
Certificated Securities under the
 
                                      91
<PAGE>
 
Indenture, then, upon surrender by the Global Note Holder of its Global Note,
Senior Notes in such form will be issued to each Person that the Global Note
Holder and the Depositary identify as being the beneficial owner of the
related Senior Notes.
 
  Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Senior Notes, and the Company and the Trustee may conclusively rely on, and
will be protected in relying on, instructions from the Global Note Holder or
the Depositary for all purposes.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
  The Indenture will require that payments in respect of the Senior Notes
represented by the Global Senior Note (including principal, premium, if any,
interest and Liquidated Damages, if any) be made in immediately available
funds. With respect to Certificated Securities, however, the Company will make
all payments of principal, premium, if any, interest and Liquidated Damages,
if any, by mailing a check to each Holder's registered address. Secondary
trading in long-term notes and debentures of corporate issuers is generally
settled in clearinghouse or next-day funds. In contrast, the Senior Notes
represented by the Global Note are expected to be eligible to trade in the
PORTAL Market and to trade in the Depositary's Same-Day Funds Settlement
System, and any permitted secondary market trading activity in such Senior
Notes will, therefore, be required by the Depositary to be settled in
immediately available funds. The Company expects that secondary trading in the
Certificated Securities will also be settled in immediately available funds.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion is a summary of certain federal income tax
considerations relevant to the exchange of the Old Notes for the New Notes,
but does not purport to be a complete analysis of all potential tax effects.
The discussion is based upon the Code, Treasury Regulations, Internal Revenue
Service ("IRS") rulings and pronouncements and judicial decisions now in
effect, all of which are subject to change at any time by legislative,
judicial or administrative action. Any such changes may be applied
retroactively in a manner that could adversely affect a holder of the New
Notes. The following discussion assumes that holders hold the Old Notes and
the New Notes as capital assets within the meaning of Section 1221 of the
Code.
 
  The Company has not sought and will not seek any rulings from the IRS with
respect to the positions of the Company discussed below. There can be no
assurance that the IRS will not take a different position concerning the tax
consequences of the exchange of the Old Notes for the New Notes or that any
such position would not be sustained.
 
  The tax treatment of a holder may vary depending on his or its particular
situation or status. This summary does not address the tax consequences to
taxpayers who are subject to special rules such as insurance companies, tax-
exempt organizations, financial institutions, broker-dealers, foreign entities
and individuals, persons holding Old Notes or New Notes as a part of a hedging
or conversion transaction or a straddle and holders whose "functional
currency" is not the U.S. dollar, or aspects of federal income taxation that
may be relevant to a prospective investor based upon such investor's
particular tax situation. In addition, the description does not consider the
effect of any applicable foreign, state, local or other tax laws.
 
  EACH HOLDER SHOULD CONSULT HIS OR ITS OWN TAX ADVISER AS TO THE PARTICULAR
TAX CONSEQUENCES TO HIM OR IT OF EXCHANGING OLD NOTES FOR NEW NOTES, INCLUDING
THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
EXCHANGE
 
  The exchange of the New Notes for Old Notes should not constitute a
recognition event for federal income tax purposes. Consequently, no gain or
loss should be recognized by holders upon receipt of the New Notes. For
 
                                      92
<PAGE>
 
purposes of determining gain or loss upon the subsequent exchange of New
Notes, a holder's basis in the New Notes will be the same as a holder's basis
in the Old Notes exchanged therefor. Holders should be considered to have held
the New Notes from the time of their original acquisition of the Old Notes. As
used herein, the term "Senior Note" refers to both an Old Note and a New Note
received in exchange therefor.
 
THE SENIOR NOTES
 
  Original Issue Discount. The Senior Notes will be issued with original issue
discount ("OID") for federal income tax purposes. Accordingly, a holder
generally will be required to recognize taxable income with respect to the
Senior Notes as the OID accrues, regardless of the holder's method of income
tax accounting.
 
  The amount of OID on a Senior Note will be equal to the excess of the
"stated redemption price at maturity" of the Senior Note over the issue price
of the Senior Note. The stated redemption price at maturity of each Senior
Note will be the sum of all payments, including principal and interest,
required to be made thereunder until maturity. The issue price of a Senior
Note will be equal to that portion of the issue price of the Unit allocable to
the Senior Note. Accordingly, the Senior Notes will be issued with a
substantial amount of OID.
 
  Taxation of Original Issue Discount. A holder of a Senior Note is required
to include in gross income an amount equal to the sum of the "daily portions"
of the OID for the Senior Note for all days during the taxable year in which
such holder holds the Senior Note ("accrued OID") without regard to when the
cash to which such income is attributable is received. The daily portion of
OID is determined by allocating to each day in any "accrual period" a pro rata
portion of OID allocable to that accrual period. The amount of OID allocable
to any full accrual period is an amount equal to the product of the Senior
Note's adjusted issue price at the beginning of such accrual period and its
yield to maturity (determined on the basis of compounding at the close of each
accrual period and properly adjusted for the length of the accrual period).
OID allocable to the final accrual period is the difference between the amount
payable at maturity and the adjusted issue price at the beginning of the final
accrual period. Special rules apply for calculating OID for an initial short
accrual period. The "adjusted issue price" of a Senior Note at the beginning
of any accrual period is equal to its issue price increased by the accrued OID
for each prior accrual period and reduced by the amount of any payments made
on such Senior Note on or before the first day of the accrual period. The
yield-to-maturity is the discount rate that, when used in computing the
present value of all principal and interest payments to be made on the Senior
Note, produces an amount equal to its issue price.
 
  The accrual period generally is the six-month period ending on the day in
each calendar year corresponding to the day before the maturity date of the
Senior Note or the date six months before such day. The initial accrual period
of a Senior Note is the short period beginning on the issue date and ending
before the first day of the first full accrual period.
 
 Applicable High Yield Discount Obligation
 
  If the yield-to-maturity on the Senior Notes equals or exceeds the sum of
(x) the applicable federal long-term rate (a rate published by the IRS each
month for application during the following month) in effect at the time of
issuance of the Senior Notes (the "AFR") plus (y) five percentage points, the
Senior Notes will be considered "applicable high yield discount obligations"
under Section 163(i) of the Code. If so, the Company will not be allowed to
take a deduction for interest (including OID) accrued on the Senior Notes for
federal income tax purposes until such time as the Company actually pays such
interest (including OID) in cash or in other property (other than stock or
debt of the Company or certain related persons).
 
  Moreover, if the yield-to-maturity on the Senior Notes exceeds the sum of
(x) the AFR and (y) 6% (such excess shall be referred to hereafter as the
"Disqualified Yield"), the deduction for interest (including OID) accrued on
the Senior Notes will be permanently disallowed (regardless of whether the
Company actually pays such interest or OID in cash or in other property) for
federal income tax purposes to the extent such interest or
 
                                      93
<PAGE>
 
OID is attributable to the Disqualified Yield on the Senior Notes ("Dividend-
Equivalent Interest"). For purposes of the dividends-received deduction, such
Dividend-Equivalent Interest will be treated as a dividend to the extent it is
deemed to have been paid out of the Company's current or accumulated earnings
and profits. Accordingly, a holder of a Senior Note that is a corporation may
be entitled to take a dividends-received deduction with respect to any
Dividend-Equivalent Interest received by such corporate holder on such Senior
Note.
 
  Sale, Redemption, Retirement or Other Taxable Disposition of Senior
Notes. In general, the holder of a Senior Note will recognize gain or loss
upon the sale, redemption, retirement or other taxable disposition of the
Senior Note measured by the difference between (i) the amount of cash and the
fair market value of property received in exchange therefor and (ii) the
holder's adjusted tax basis in the Senior Note.
 
  An initial holder's tax basis in a Senior Note will generally be equal to
the portion of the issue price of a Unit allocated to such Senior Note
increased by the OID previously includible in gross income and reduced by any
payments on the Senior Note.
 
  Any gain or loss on the sale, redemption, retirement or other taxable
disposition of a Senior Note should be capital gain or loss, provided the
Senior Note was a capital asset in the hands of the holder. Any capital gain
or loss will be long-term capital gain or loss if the Senior Note has been
held for more than one year and otherwise will be short-term capital gain or
loss.
 
  Holders should be aware that the resale of a Senior Note may be affected by
the "market discount" rules of the Code under which a subsequent purchaser of
Senior Note acquiring the Senior Note at a market discount generally would be
required to include as ordinary income a portion of the gain realized upon the
disposition or retirement of such Senior Note to the extent of the market
discount that has accrued while the debt instrument was held by such holder.
 
INFORMATION REPORTING; BACKUP WITHHOLDING
 
  The Company is required to furnish certain information to the IRS, and will
furnish annually to record holders of the Senior Notes, other than
corporations and other exempt holders, information with respect to interest
paid and the amount of OID accrued on the Senior Notes. Holders who purchase
Senior Notes for an amount other than the adjusted issue price and/or on a
date other than the first day of an accrual period are required to determine
for themselves the amount of OID, if any, they are required to include in
gross income for federal income tax purposes.
 
  The backup withholding rules require a payor to deduct and withhold a tax if
(i) the payee fails to furnish a taxpayer identification number ("TIN") to the
payor, (ii) the IRS notifies the payor that the TIN furnished by the payee is
incorrect, (iii) the payee has failed to report properly the receipt of a
"reportable payment" on one or more occasions and the IRS has notified the
payor that withholding is required, or (iv) there has been a failure of the
payee to certify under the penalty of perjury that the payee is not subject to
withholding under Section 3406 of the Code. If any one of the foregoing events
occurs, the Company, its paying agent or other withholding agent will be
required to withhold a tax equal to 31% of any "reportable payment" made in
connection with the Senior Notes. A "reportable payment" includes, among other
things, interest (including OID) paid in respect of a Senior Note and amounts
paid through brokers in retirement of a Senior Note. Any amounts withheld from
a payment to a holder under the backup withholding rules will be allowed as a
refund or credit against such holder's federal income tax, provided that the
required information is furnished to the IRS. Certain holders (including,
among others, corporations and certain tax-exempt organizations) are not
subject to the backup withholding and information reporting requirements. A
holder should consult his or its tax advisor as to his or its qualification
for exemption from backup withholding and the procedure for obtaining such an
exemption.
 
 
                                      94
<PAGE>
 
DEDUCTIBILITY OF ORIGINAL ISSUE DISCOUNT
 
  The deduction by the Company in respect of OID accrued with respect to the
Senior Notes will be limited in part and deferred in part if the Senior Notes
are "applicable high yield discount obligations." The Company anticipates that
the Senior Notes will be applicable high yield discount obligations because,
among other things, it is expected that the yield to maturity of the Senior
Notes will exceed the sum of the AFR plus five percentage points. If the
Senior Notes are applicable high yield discount obligations, then (i) if the
yield to maturity of the Senior Notes exceeds the sum of the AFR plus six
percentage points (such excess referred to below as the "Disqualified Yield"),
the deduction for OID accrued on the Senior Notes will be permanently
disallowed to the extent such OID is attributable to the Disqualified Yield,
and such OID would be treated as dividends to corporate holders of the Senior
Notes for purposes of the dividends-received deduction (to the extent that
such amounts would have been treated as dividends had they been distributions
made by the Company with respect to its stock), and (ii) the remainder of the
OID on the Senior Notes would not be deductible by the Company until paid.
 
                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of the New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes
acquired as a result of market-making activities or other trading activities.
The Company has agreed that it will make this Prospectus available to any
broker-dealer for use in connection with any such resale for a period of 365
days after the Expiration Date or until all participating broker-dealers have
so resold.
 
  The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concession from any
such broker-dealer and/or the purchasers of any New Notes. Any broker-dealer
that resells New Notes that were received by it for its own account pursuant
to the Exchange Offer and any broker-dealer that participates in a
distribution of New Notes may be deemed to be an "underwriter" within the
meaning of the Securities Act, and any profit on any resale of New Notes and
any commissions or concessions received by any such persons may be deemed to
be underwriting compensation under the Securities Act. The Letter of
Transmittal states that by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
 
  The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and
to the best of the Company's information and belief, each person participating
in the Exchange Offer is acquiring the New Notes in its ordinary course of
business and has no arrangement or understanding with any person to
participate in the distribution of the New Notes to be received in the
Exchange Offer.
 
                                 LEGAL MATTERS
 
  The validity of the New Notes will be passed upon on behalf of the Company
by Buchanan Ingersoll Professional Corporation, Pittsburgh, Pennsylvania.

INDEPENDENT AUDITORS' REPORT
 
Hyperion Telecommunications, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Hyperion
Telecommunications, Inc. and subsidiaries as of March 31, 1994 and 1995 and
December 31, 1995 and the related consolidated statements of operations,
stockholders' equity (deficiency) and cash flows for the years ended March 31,
1994 and 1995 and the nine months ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our 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, such consolidated financial statements present fairly, in
all material respects, the financial position of Hyperion Telecommunications,
Inc. and subsidiaries at March 31, 1994 and 1995 and December 31, 1995 and the
results of their operations and their cash flows for the years ended March 31,
1994 and 1995 and the nine months ended December 31, 1995 in conformity with
generally accepted accounting principles.
 
  As discussed in Note 8 to the consolidated financial statements, effective
April 1, 1993, the Company changed its method of accounting for income taxes.

   HYPERION TELECOMMUNICATIONS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED
                             FINANCIAL STATEMENTS
 
FOR THE YEARS ENDED MARCH 31, 1994 AND 1995 AND THE NINE MONTHS ENDED DECEMBER
           31, 1995 (DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

(1)THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Organization and Business
 
  The consolidated financial statements include the accounts of Hyperion
Telecommunications, Inc. and its wholly-owned subsidiaries (the "Company").
All significant intercompany accounts and transactions have been eliminated in
consolidation. The Company was formed in 1991 and is an 89% owned subsidiary
of Adelphia Communications Corporation ("Adelphia"). The remaining 11% is
owned by certain key Company officers.
 
  The Company provides telecommunications service through its subsidiaries and
joint ventures, in which it has less than a majority equity interest. The
Company's efforts have been directed primarily toward becoming an owner and
manager of competitive access providers ("CAP") of business telecommunications
services in selected mid-sized cities. The Company generally partners with a
local cable television or utility company, whose fiber facilities are located
in the market areas, to build competitive access fiber optic networks. The
Company then operates the networks for a management fee. Each network provides
local special access, carrier-to-carrier, and point-to-point
telecommunications services to major businesses and government customers. The
Company's revenues are derived from a combination of direct business
telecommunication services provided by its subsidiaries and management fees
from its unconsolidated joint ventures.
 
  Joint ventures in which the Company does not have a majority interest are
accounted for under the equity method of accounting.
 
 Cash and cash equivalents
 
  Cash and cash equivalents generally consist of highly liquid instruments
with an initial maturity date of three months or less.
 
 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost less accumulated
depreciation. Costs capitalized include amounts directly associated with
network engineering, design and construction.
 
  Provision for depreciation of property, plant and equipment is computed
using the straight-line method over the estimated useful lives of the assets
beginning in the month the asset is available for use or is acquired.
 
  The estimated useful lives of the Company's principal classes of property,
plant and equipment are as follows:
 
<TABLE>
   <S>                                                               <C>
   Telecommunications networks...................................... 10-20 years
   Network monitoring equipment.....................................  5-10 years
   Other............................................................  3-10 years
</TABLE>
 
 Revenue Recognition
 
  The Company recognizes revenues related to management and network monitoring
of the joint ventures in the month that the related services are provided. The
Company recognizes revenue from telecommunications services in the month the
related service is provided. Revenues on billings to customers for services in
advance of providing such services are deferred and recognized when earned.

FOR THE YEARS ENDED MARCH 31, 1994 AND 1995 AND THE NINE MONTHS ENDED DECEMBER
           31, 1995 (DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

(1)THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
 
 Loss Per Common Share
 
  The computation of loss per common share is based upon the weighted average
number of common shares outstanding. All references in the accompanying
consolidated financial statements to the number of shares of common stock have
been retroactively restated to reflect the stock split (See Note 5).
 
 Income Taxes
 
  Deferred income taxes are recognized for the tax effects of temporary
differences between financial statement and income tax bases of assets and
liabilities and for loss carryforwards for which income tax benefits are
expected to be realized in future years. A valuation allowance is established
to reduce deferred tax assets to the net amount that management believes will
more likely than not be realized. The effect on deferred taxes of a change in
tax rates is recognized in income in the period that includes the enactment
date.
 
 Other Assets
 
  Costs incurred in developing new networks or expanding existing networks,
including network design, negotiating rights-of-way and obtaining
legal/regulatory authorizations are deferred and amortized over five years.
Pre-operating costs represent certain nondevelopment costs incurred during the
pre-operating phase of a newly constructed network and are amortized over
five-year periods commencing with the start of operations.
 
 Asset Impairments
 
  In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 121 "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." In
accordance with SFAS No. 121, the Company reviews the carrying amounts of its
long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. Measurement of any
impairment would include a comparison of estimated future operating cash flows
anticipated to be generated during the remaining life of the assets with their
net carrying value. The adoption of SFAS No. 121 in the year ended March 31,
1995 had no effect on the consolidated financial statements of the Company.
 
 Financial Instruments
 
  Financial instruments which potentially subject the Company to concentration
of credit risk consist principally of accounts receivable. Concentration of
credit risk with respect to accounts receivable is limited due to the
dispersion of the Company's customer base among different entities and
geographic areas. The carrying value of the Note Payable--Adelphia (see Note
4) at March 31, 1994 and 1995 and December 31, 1995 approximates its fair
value based upon the terms of the note in comparison with other similar
instruments.
 
 Use of Estimates in the Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

(3)INVESTMENTS
 
  The equity method of accounting is used to account for investments in joint
ventures in which the Company owns less than a majority interest. Under this
method, the Company's initial investment is recorded at cost and subsequently
adjusted for the amount of its equity in the net income or losses of its joint
ventures. Dividends or other distributions are recorded as a reduction of the
Company's investment. Investments in joint ventures accounted for using the
equity method reflect the Company's equity in their underlying net assets.
 
  The Company's nonconsolidated investments are as follows:

  On May 16, 1996, the Company sold its 15.7% interest in TCG of South Florida
to a third party for approximately $11,618 cash resulting in a pre-tax gain of
approximately $8,400. Amounts related to TCG of South Florida included in the
Company's investments and equity in net loss of joint ventures as of and for
the nine months ended December 31, 1995 were $2,947 and $582, respectively.
 
(4)FINANCING ARRANGEMENTS
 
 Note Payable--Adelphia
 
  The Company has an unsecured credit arrangement with Adelphia which had no
repayment terms prior to April 15, 1996. On April 15, 1996, $25,000 of the
proceeds from the sale of the 13% Senior Discount Notes and Warrants discussed
below were used to repay a portion of this obligation. Interest expense and
fees on this credit arrangement were based upon the weighted average cost of
unsecured borrowings of Adelphia during the corresponding periods.
 
  Interest at 11.28% per annum plus fees was charged on the Note Payable--
Adelphia for the years ended March 31, 1994 and 1995 and the nine months ended
December 31, 1995. The total amount of interest converted to note principal at
December 31, 1995 is $8,098.
 
  Effective April 15, 1996, the remaining balance due on the Note Payable--
Adelphia is evidenced by an unsecured subordinated note due April 16, 2003.
This obligation bears interest at 16.5% per annum with interest payable
quarterly in cash; by issuing additional subordinated notes; or a combination
of cash and additional subordinated notes, all of which is at the Company's
option.
 
 13% Senior Discount Notes and Warrants
 
  On April 15, 1996, the Company issued $329,000 of 13% Senior Discount Notes
(the "Senior Notes") due April 15, 2003 and 329,000 warrants to purchase an
aggregate of 613,427 shares of its common stock. Proceeds to the Company, net
of discounts, commissions, and other transaction costs were approximately
$168,600. Such net proceeds were used to pay $25,000 of the Note Payable--
Adelphia discussed above, to make loans of $3,000 to certain key Company
officers (see Note 5) and to be used to fund the Company's capital
expenditures, working capital requirements, operating losses and its pro-rata
investments in joint ventures. Use of proceeds from the Senior Notes also
included the repayment of amounts related to capital expenditures, working
capital requirements, operating losses and pro-rata investments in joint
ventures totaling $12,800 incurred during the period from January 1, 1996 to
April 15, 1996. These amounts had been funded during the same time period
through advances from Adelphia.

(4) FINANCING ARRANGEMENTS, CONTINUED
 
  Prior to April 15, 2001, interest on the Senior Notes is not payable in
cash, but is added to principal. Thereafter, interest is payable semi-annually
commencing October 15, 2001. The Senior Notes are unsecured and are senior to
the Note Payable--Adelphia and all future subordinated indebtedness. On or
before April 15, 1999 and subject to certain restrictions, the Company may
redeem, at its option, up to 25% of the aggregate principal amount of the
Senior Notes at a price of 113% of the Accreted Value (as defined in the
Indenture). On or after April 15, 2001, the Company may redeem, at its option,
all or a portion of the Senior Notes at 106.5% which declines to par in 2002,
plus accrued interest.
 
  The holders of the Senior Notes may put the Senior Notes to the Company at
any time at a price of 101% upon the occurrence of a Change of Control (as
defined in the Indenture). In addition, the Company will be required to offer
to purchase Senior Notes at a price of 100% with the proceeds of certain asset
sales (as defined in the Indenture).
 
  The Indenture stipulates, among other things, limitations on additional
borrowings, issuance of equity instruments, payment of dividends and other
distributions, repurchase of equity interests or subordinated debt, sale and
lease back transactions, liens, transactions with affiliates, sales of Company
assets, mergers and consolidations.
 
  In accordance with a registration rights agreement, the Company has agreed
to file a registration statement offering to exchange the Senior Notes for
Series B Senior Discount Notes registered under the Securities Act of 1933, as
amended (the "Securities Act"). Terms of the Series B Senior Discount Notes
will be substantially the same as the Senior Notes. Under certain
circumstances, if the above exchange is not consummated or such registration
is not filed or effective within the time periods stipulated in the agreement,
the Company must pay liquidated damages to the holders of the Senior Notes
ranging from .5% per annum to 2.0% per annum based on the amount of additional
time required to consummate the exchange. The Company is in the process of
filing the required registration statement and does not expect to incur any
liquidated damages.
 
  The Warrants are exercisable at $.01 per share upon the earlier of May 1,
1997 or a Change of Control. Unless exercised, the Warrants expire on April 1,
2001. The number of shares and the exercise price for which a warrant is
exercisable are subject to adjustment under certain circumstances. In
accordance with a registration rights agreement, the Company has agreed to
file shelf registration statements under the Securities Act covering the
Warrants and the Warrant Shares. Under certain circumstances, if the shelf
registrations are not effective within the time period specified in the
agreement, the Company must pay liquidated damages to the holders of the
Warrants or Warrant Shares ranging from $.0025 to $.0125 per week per Warrant
or per Warrant Share then issuable based on the amount of additional time
required to accomplish the shelf registrations.
 
  If the Senior Notes and Warrants had been issued on April 1, 1995, interest
expense would have been $20,076 for the nine months ended December 31, 1995.

(5)STOCKHOLDERS' EQUITY
 
  The common stock of the Company held by Adelphia and certain key Company
officers (the "Officers") is subject to sale and transfer restriction
provisions. These provisions state that none of the Officers may transfer any
shares unless they have offered to sell such shares to Adelphia (or the other
remaining Officers if Adelphia declines) at a price per share equal to the
terms of the proposed third party sale or exchange.
 
  In accordance with a shareholder agreement, upon termination of employment
or at any time after October 7, 1996, the Officers could have required
Adelphia to purchase all their outstanding shares (the "Officers' Option"). At
any time after October 7, 2001, Adelphia could have required the Officers to
sell all of their outstanding shares to Adelphia (the "Adelphia Option"). The
price per share shall be equal to the fair market value of the shares as
determined by a nationally recognized financial advisor selected by Adelphia
and the Officers.
 
  On March 19, 1996, such shareholder agreement was amended primarily to (i)
grant the Officers certain registration rights regarding their common stock;
(ii) extend the Officers' Option date until after October 7, 1998; (iii)
extend the Adelphia Option date until after October 7, 2003 and (iv) provide
for aggregate loans to the Officers of $3,000 from the proceeds received from
the private placement of the Senior Notes and Warrants discussed in Note 4.
Such loans, including accrued interest at a rate equal to the rate which the
Company is able to invest cash on a short-term basis, are secured by a pledge
of each Officer's common stock in the Company and are payable to the Company
on the earlier of October 8, 1998 or the date of the registration of an equity
security of the Company as described below. Also, an amount equal to the
interest that accrues on such loans from the date six months after the date
the loans are made until due and payable will be satisfied through additional
compensation to the Officers. The shareholder agreement is terminated upon the
registration of an equity security of the Company under the Federal Securities
Act of 1933, as amended, or the Federal Securities Exchange Act of 1934, as
amended, which equity security is of the same class as the equity security
held by the Officers.
 
  On March 19, 1996, the Board of Directors of the Company approved a ten
thousand-for-one stock split of its common stock and the reduction of the par
value from $1.00 per share to $.01 per share. All references in the
accompanying consolidated financial statements to the number of shares of
common stock and the par value have been retroactively restated to reflect
this stock split and par value reduction. In addition, on March 19, 1996, the
Board of Directors approved charter amendments to increase the Company's
authorized shares of common stock from 1,000 shares to 30,000,000 shares and
authorized 5,000,000 shares of preferred stock with terms of such preferred
stock to be determined by the Board of Directors of the Company. No preferred
stock has been issued by the Company.
 
(6)COMMITMENTS AND CONTINGENCIES
 
  The Company rents office space, node space and fiber under leases with terms
which are generally less than one year or under agreements that are generally
cancelable on short notice. Total rental expense under all operating leases
aggregated $65, $478, and $906 for the years ended March 31, 1994 and 1995 and
the nine months ended December 31, 1995, respectively.

  Under certain investment agreements, the Company has committed to make
specific capital contributions to the joint ventures. Total capital
commitments to be made as a result of these agreements at December 31, 1995
was $1,278.
 
  Certain investors in two of the joint ventures have the right after a
specified period of time to sell their interest to the Company. Under one
agreement, the sales price represents the investor's aggregate capital
contribution less distributions plus interest accrued at the prime rate. The
Company's obligation under this commitment at December 31, 1995 was
approximately $2,700. The sales price under the second agreement is equal to
the fair market value of such investor's interest.
 
 
  The Company has agreed that it will make all required capital contributions
to Louisville Lightwave that are necessary to increase its ownership to 50%.
The Company expects these capital contributions will aggregate approximately
$2,700.
 
  Under a letter of intent signed on February 12, 1996, the Company agreed to
increase its ownership in Hyperion of Tennessee to at least 51% and as much as
95% by purchasing interests held by another existing owner of Hyperion of
Tennessee at the option of such other owner. The Company expects these capital
contributions will aggregate a maximum of approximately $4,900.
 
  The consummation of any of the proposed transactions described above is
subject to the negotiation and execution of definitive, binding agreements and
to numerous other terms and conditions.
 
  The Company has entered into employment agreements with certain key Company
officers, the terms of which expire on October 20, 1998, as amended. The
employment agreements provide for base salary, benefits and bonuses payable if
specified management goals are attained. In addition, the employment
agreements contain noncompetition and nondisclosure provisions.
 
  The President of the Company has an employment agreement with Adelphia where
he is a vice president and secretary. His agreement provides for base salary,
benefits and insurance premium payments. The Company reimburses Adelphia for
such payments.
 
  The Company's operations and the operations of its joint ventures may be
adversely affected by changes and developments in governmental regulation,
competitive forces and technology. The telecommunications industry is subject
to extensive regulation at the federal, state and local levels. On February 8,
1996, President

(6) COMMITMENT AND CONTINGENCIES, CONTINUED
 
Clinton signed the Telecommunications Act of 1996 (the "Telecommunications
Act"), the most comprehensive reform of the nation's telecommunications laws
since the Communications Act of 1934.
 
  The more significant provisions of the Telecommunications Act and certain
  of its possible effects are as follows:
 
  The Telecommunications Act removes legal barriers of entry in local
  telephone markets. This provision should enable the Company to provide a
  full range of services in any state while potentially increasing the level
  of competition the Company faces in all its markets.
 
  The Telecommunications Act requires incumbent Local Exchange Company's
  ("LECs") to "interconnect" with competitors which will provide access to
  certain networks under reasonable rates, terms and conditions. It is
  uncertain how effective these requirements will be or their impact on the
  Company until the FCC completes its rulemaking proceedings requiring the
  LECs to provide telephone number portability, dialing parity, reciprocal
  compensation, resale, access to rights-of-way and unbundling of network
  services.
 
  The Telecommunications Act establishes procedures for LEC and Bell
  Operating Company ("BOC") entry into new markets, including long distance
  and cable television service. The Company's management believes LECs are
  now more likely to invest in fiber optic networks and enter the video
  market which will generate a revenue stream previously unavailable to them.
  These facilities can then also be used to provide services that compete
  with the Company. By allowing the BOC to enter the long distance market,
  this may reduce the market share of the major long distance carriers (the
  Company's joint ventures' primary customers) and have adverse consequences
  on the Company's joint ventures' ability to generate revenues from the long
  distance carriers.
 
 
  The Telecommunications Act eliminates the requirement that LECs obtain FCC
  authorization before constructing new facilities for interstate services
  and limits the FCC's ability to review LEC tariff filings. The changes will
  increase the speed with which the LECs are able to introduce new service
  offerings and new pricing of existing services, thereby increasing the
  LEC's ability to compete with the Company.
 
  The Telecommunications Act requires the FCC to establish an explicit
  mechanism for subsidizing service to markets that are less desirable,
  either because of the high cost of providing service or the limited
  revenues that might be available. This could be advantageous to the Company
  or it could be beneficial to the Company's competitors depending on the
  geographic areas and the type of customers for which subsidies are
  available.

(8)INCOME TAXES, CONTINUED
 
  Adelphia and its corporate subsidiaries (including the Company) file a
consolidated federal income tax return. For financial reporting purposes,
current and deferred income tax assets and liabilities are computed on a
separate company basis. The valuation allowance is adjusted for benefits
associated with filing a consolidated income tax return, similar to provisions
of the Internal Revenue Code. At December 31, 1995, the Company had net
operating loss carryforwards for federal income tax purposes of $24,778
expiring through 2010.
 
  Deferred income taxes reflect the net tax effects of (a) temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes and
(b) operating loss carryforwards.
 
  Temporary differences and carryforwards that give rise to deferred tax
assets and liabilities are as follows:

                                  APPENDIX A
 
                                   GLOSSARY
 
  Access Charges--The fees paid by long distance carriers to LECs for
originating and terminating long distance calls over the LECs' local networks.
 
  ATM (Asynchronous Transfer Mode)--A recently commercialized switching and
transmission technology that is one of a general class of packet technologies
that relay traffic by way of an address contained within the first five bits
of a standard fifty-three bit-long packet or cell. ATM-based packet transport
was specifically developed to allow switching and transmission of mixed voice,
data and video (sometimes referred to as "multi-media" information) at varying
rates. The ATM format can be used by many different information systems,
including LANs.
 
  Broadband--Broadband communications systems can transmit large quantities of
voice, data and video by way of digital or analog signals. Examples of
broadband communication systems include DS-3 fiber optic systems, which can
transmit 672 simultaneous voice conversations, or a broadcast television
station signal, that transmits high resolution audio and video signals into
the home. Broadband connectivity is also an essential element for interactive
multimedia applications.
 
  CAP (Competitive Access Provider)--A company that provides its customers
with an alternative to the incumbent local telephone company for local
transport of private line, special access and interstate transport of switched
access telecommunications services. CAPs are also referred to in the industry
as alternative local telecommunications service providers (ALTs), metropolitan
area network providers (MANs) and alternative access vendors (AAVs).
 
  Central Offices or LEC-COs--The switching centers or central switching
facilities of the LECs or CLECs.
 
  Centrex--Centrex is a service that offers features similar to those of a
Private Branch Exchange (PBX), except the equipment is located at the
carrier's premises and not at the premises of the customer. These features
include direct dialing within a given phone system, direct dialing of incoming
calls, and automatic identification of outbound calls. This is a value-added
service that LECs and CLECs can provide to a wide range of customers who do
not have the size or the funds to support their own on-site PBX.
 
  CLEC (Competitive Local Exchange Carrier)--A CAP that also provides switched
local telecommunications services.
 
  Collocation--The ability of a CAP, IXC or end user to connect its network to
a LEC-COs. Physical collocation occurs when a CAP places its network
connection equipment inside the LEC-COs. Virtual collocation is an alternative
to physical collocation pursuant to which the LEC permits a CAP to connect its
network to the LEC-COs on comparable terms, even though the CAP's network
connection equipment is not physically located inside the central offices.
 
  Dedicated Lines--Telecommunications lines dedicated or reserved for use
exclusively by particular customers along predetermined routes (in contrast to
telecommunications lines within the public switched network).
 
  Digital--A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary code digits 0 and 1. Digital transmission and switching technologies
employ a sequence of these pulses to represent information as opposed to the
continuously variable analog signal. Digital transmission and switching
technologies offer a threefold improvement in speed and capacity over analog
techniques, allowing much more efficient and cost-effective transmission of
voice, video and data.
 
                                      A-1
<PAGE>
 
  Dialing Parity--Dialing parity exists when a customer calling to or from the
network of a CLEC is not required to dial any more digits than for a
comparable call originating and terminating on the incumbent LEC's network.
 
  Diverse Access Routing--A telecommunications network configuration in which
signals are transported simultaneously along two different paths so that if
one cable is cut, traffic can continue in the other direction without
interruption to its destination. The Company's networks generally provide
diverse access routing.
 
  DS-0, DS-1, DS-3--Standard telecommunications industry digital signal
formats, which are distinguishable by bit rate (the number of binary digits (0
and 1) transmitted per second). DS-0 service has a bit rate of 64 kilobits per
second. DS-1 service has a bit rate of 1.544 megabits per second and DS-3
service has a bit rate of 45 megabits per second.
 
  FCC--Federal Communications Commission
 
  Fiber Mile--The number of route miles installed (excluding pending
installations) along a telecommunications path multiplied by the number of
fibers along that path. See the definition of "route mile" below.
 
  Fiber Optics--Fiber optic cable is the medium of choice for the
telecommunications and cable industries. Fiber is immune to electrical
interference and environmental factors that affect copper wiring and satellite
transmission. Fiber optic technology involves sending laser light pulses
across glass strands in order to transmit digital information. A strand of
fiber optic cable is as thick as a human hair yet is said to have more
bandwidth capacity than copper cable the size of a telephone pole.
 
  Fiber Optic Ring Network--Most CAPs have built their networks in ring
configurations in order to ensure that, if one segment of a network is damaged
or cut, the traffic is simply re-routed and sent to its destination in the
opposite direction. The Company uses a "self-healing" optical fiber ring
architecture known as SONET.
 
  Frame Relay--Frame relay is a high speed data packet switching service used
to transmit data between computers. Frame relay supports data units of
variable lengths at access speeds ranging from 56 kilobits to 1.5 megabits.
This service is appropriate for connecting LANs, but is not appropriate for
voice and video applications due to the variable delays which can occur. Frame
relay was designed to operate at higher speeds on modern fiber optic networks.
 
  Frame Relay Service--Data communications service that functions as a fast
packet transport service of variable length data packets between customer
designated locations and supports the establishment of software defined
logical connections and circuits that act as private facilities on a public
platform.
 
  Hubs--Collection centers located centrally in an area where
telecommunications traffic can be aggregated at a central point for transport
and distribution.
 
  Interconnection Decisions--Rulings by the FCC announced in September 1992
and August 1993, which require the RBOCs and most other LECs to provide
interconnection in LEC-COs to any CAP, IXC or end user seeking such
interconnection for the provision of interstate special access and switched
access transport services.
 
  lnterLATA Calls--InterLATA calls are calls that pass from one LATA to
another. Typically, these calls are referred to as long distance calls. The
Telecommunications Act establishes procedures under which the RBOCs can
receive authority to provide interLATA services.
 
                                      A-2
<PAGE>
 
  IntraLATA Calls--IntraLATA calls, also known as short haul calls, are those
calls that originate and terminate within the same LATA. All states allow
intraLATA competition, but dialing parity still does not exist in most states
and very little LEC intraLATA revenue has been won by competitors.
 
  IXC (Interexchange or Long Distance Carriers)--Usually referred to as long
distance carriers. There are many facilities-based IXCs, including AT&T, MCI,
WorldCom and Sprint, as well as a select few CAPs that provide interexchange
service.
 
  Kilobit--One thousand bits of information. The information-carrying capacity
(i.e., bandwidth of a circuit may be measured in "kilobits per second.")
 
  LANs (Local Area Networks)--The interconnection of computers for the purpose
of sharing files, programs and various devices such as work stations, printers
and high-speed modems. LANs may include dedicated computers or file servers
that provide a centralized source of shared files and programs.
 
  LATAs--The geographically defined Local Access and Transport Areas in which
LECs are authorized by the MFJ to provide local exchange services. These LATAs
roughly reflect the population density of their respective states (for example
California has 11 LATAs while Wyoming has one). There are 164 LATAs in the
United States.
 
  LEC (Local Exchange Carrier)--A company providing local telephone services.
 
  LEC-COs--Local Exchange Carrier's central office.
 
  Local Exchange Areas--A geographic area determined by the appropriate state
regulatory authority in which local calls generally are transmitted without
toll charges to the calling or called party.
 
  Megabit--One million bits of information. The information-carrying capacity
(i.e., bandwidth) of a circuit may be measured in "megabits per second."
 
  MFJ (Modified Final Judgment)--The MFJ was a consent decree entered into in
1982 between AT&T and the Department of Justice which forced the breakup of
the old Bell System through the divestiture of the seven separate Regional
Bell Operating Companies (RBOCs) from AT&T. Divestiture resulted in two
distinct segments of the telecommunications service market: local and long
distance. This laid the groundwork for intense competition in the long
distance industry, but essentially created seven separate regionally-based
local exchange service monopolies. The Telecommunications Act removes most MFJ
restrictions on a prospective basis from AT&T and the RBOCs.
 
  Network Systems Integration--Involves the creation of a turnkey
telecommunications network including (i) route and site selection and
obtaining rights of way and legal authorizations to install the network; (ii)
design and engineering of the system, including technology and vendor
assessment and selection, determining fiber optic circuit capacity, and
establishing reliability/flexibility standards; and (iii) project and
construction management, including contract negotiations, purchasing and
logistics, installation as well as testing and construction management.
 
  Number Portability--The ability of an end user to change local exchange
carriers while retaining the same telephone number.
 
  Off-Net--A customer that is not physically connected to one of the Company's
networks but who is accessed through interconnection with a LEC network.
 
  On-Net--A customer that is physically connected to one of the Company's
networks.
 
                                      A-3
<PAGE>
 
  PCS (Personal Communications Service)--A type of wireless telephone system
that uses light, inexpensive handheld sets and communicates via low power
antennas.
 
  PBX--A Private Branch Exchange is a switching system within an office
building which allows calls from outside to be routed directly to the
individual instead of through a central number. A PBX also allows for calling
within an office by way of four digit extensions. Centrex is a service which
can simulate this service from an outside switching source, thereby
eliminating the need for a large capital expenditure on a PBX.
 
  Physical Collocation--Physical Collocation occurs when a CAP places its own
network connection equipment inside the LEC-CO. The Telecommunications Act
gives the FCC authority to mandate physical collocation. See Virtual
Collocation.
 
  POPs (Points of Presence)--Locations where an IXC has installed transmission
equipment in a service area that serves as, or relays calls to, a network
switching center of that IXC.
 
  Private Line--A private, dedicated telecommunications connection between
different end user locations (excluding IXC POPs).
 
  Private Line Data Interconnect Service--A data transport service utilizing
data products and on-net private line facilities that are packaged together
with data products.
 
  Public Switched Network--That portion of a LEC's network available to all
users generally on a shared basis (i.e., not dedicated to a particular user).
 
  Public Utility Commission--A state regulatory body which regulates
utilities, including telephone companies providing intrastate services. In
some states this regulatory body may have a different name, such as public
service commission.
 
  RBOCs (Regional Bell Operating Companies)--The seven local telephone
companies established by the MFJ. The RBOCs were prohibited from providing
interLATA services and from manufacturing telecommunications equipment under
the MFJ, but the Telecommunications Act of 1996 establishes procedures for
lifting these restrictions.
 
  Reciprocal Compensation--The compensation paid by a local carrier for
termination of a local call on the network of a competing carrier which is
obligated to pay a comparable charge to terminate traffic on the network of
the first carrier. Reciprocal compensation is distinct from the one way access
charges by which the IXCs compensate LEC's for originating or terminating
traffic.
 
  Redundant Electronics--A telecommunications facility using two separate
electronic devices to transmit a telecommunications signal so that if one
device malfunctions, the signal may continue without interruption.
 
  Route Miles--The number of miles of the telecommunications path in which
fiber optic cables are installed as it would appear on a network map.
 
  Second and Third Tier Markets--Metropolitan markets in the United States
with population bases ranging from 250,000 to two million.
 
  Special Access Services--The lease of private, dedicated telecommunications
lines or "circuits" along the network of a LEC or a CAP, which lines or
circuits run to or from the IXC POPs. Examples of special access services are
telecommunications lines running between POPs of a single IXC, from one IXC
POP to the POP of another IXC or from an end user to its IXC POP. Special
access services do not require the use of switches.
 
                                      A-4
<PAGE>
 
  SONET (Synchronous Optical Network)--SONET is the electronics and network
architecture which enable transmission of voice, video and data (multimedia)
at very high speeds. This state-of-the-art self-healing ring network offers
advantages over older linear networks in that a cut line or equipment failure
can be overcome by re-routing calls within the network. If the line is cut,
the traffic is simply reversed and sent to its destination around the other
side of the ring.
 
  Switch--A sophisticated computer that accepts instructions from a caller in
the form of a telephone number. Like an address on an envelope, the numbers
tell the switch where to route the call. The switch opens or closes circuits
or selects the paths or circuits to be used for transmission of information.
Switching is a process of interconnecting circuits to form a transmission path
between users. Switches allow local telecommunications service providers to
connect calls directly to their destination, while providing advanced features
and recording connection information for future billing.
 
  Switched Access Transport Services--Transportation of switched traffic along
dedicated lines between the LEC central offices and IXC POPs.
 
  Switched Services--Services which utilize a switch, as opposed to dedicated
services which are non-switch. These services are the greatest source of
revenue for carriers.
 
  Switched Traffic--Telecommunications traffic along a switched network.
 
  Virtual Collocation--Virtual collocation is an alternative to physical
collocation in which the CAPs connect their equipment to the LECs facilities
from a remote location and request that the LEC install the necessary
electronics in its central office which is then leased by the LEC to the CAP
for charges which are generally higher than the charges for physical
collocation. However, the CAP avoids payment of the initial capital costs for
the leased facilities which the CAP must incur under physical collocation.
 
  Voice Grade Equivalent Circuit--One DS-0. One voice grade equivalent circuit
is equal to 64 kilobits of bandwidth per second.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law provides in general that
a corporation may indemnify its directors, officers, employees or agents
against expenditures (including judgments, fines, amounts paid in settlement
and attorneys' fees) made by them in connection with certain lawsuits to which
they may be made parties by reason of their being directors, officers,
employees or agents and shall so indemnify such persons against expenses
(including attorneys' fees) if they have been successful on the merits or
otherwise. The bylaws of Hyperion provide for indemnification of the officers
and directors of Hyperion to the full extent permissible under Delaware law.
 
  Hyperion's Certificate of Incorporation also provides, pursuant to Section
102(b)(7) of the Delaware General Corporation Law, that directors of Hyperion
shall not be personally liable to Hyperion or its stockholders for monetary
damages for breach of fiduciary duty as a director for acts or omissions,
provided that directors shall nonetheless be liable for breaches of the duty
of loyalty, bad faith, intentional misconduct, knowing violations of law,
unlawful distributions to stockholders, or transactions from which a director
derived an improper personal benefit.

ITEM 22. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.
 
                                     II-2

  The Registrant hereby undertakes to respond to requests for information that
is incorporated by reference into the prospectus pursuant to Item 4, 10(b),
11, or 13 of this form, within one business day of receipt of such request,
and to send the incorporated documents by first-class mail or other equally
prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the
date of responding to the request.
 
  The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.
 
  The undersigned Registrant hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of a
Registration Statement in reliance upon Rule 430A and contained in the form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act of 1933 shall be deemed part of the Registration
Statement as of the time it was declared effective.
 
  (2) For purposes of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at such time shall be
deemed to be the initial bona fide offering thereof.
 
  (3) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
    (i) To include any prospectus required by section 10(a)(3) of the
  Securities Act of 1933;
 
    (ii) To reflect in the prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement;
 
    (iii) To include any material information with respect to the plan of
  distribution not previously disclosed in the registration statement or any
  material change to such information in the registration statement.
 
Provided, however, that paragraphs (3)(i) and (3)(ii) above do not apply if
the registration statement is on Form S-3 or Form S-8, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to section 13 or section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement.
 
  (4) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  (5) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.
 
  (6) For purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant's annual report pursuant to section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant
to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated
by reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

          -------------------------                                            
Initial Purchasers as follows:

          (a) To advise the Initial Purchasers promptly and, if requested by the
     Initial Purchasers, confirm such advice in writing of; (i) the issuance by
     any state securities commission of any stop order suspending the
     qualification or exemption from qualification of any Securities for
     offering or sale in any jurisdiction, or the initiation of any proceeding
     for such purpose by any state securities commission or other regulatory
     authority; and (ii) the happening of any event that, in the reasonable
     opinion of either counsel to the Company or counsel to the Initial
     Purchasers, makes any statement of a material fact made in the Preliminary
     Offering Memorandum or the Offering Memorandum untrue or that requires the
     making of any additions to or changes in the Preliminary Offering
     Memorandum or the Offering Memorandum in order to make the statements
     therein, in the light of the circumstances under which they are made, not
     misleading. The Company shall use its best efforts to prevent the issuance
     of any stop order or order suspending the qualification or exemption of any
     Securities under any state securities or Blue Sky laws and, if at any time
     any state securities commission or other regulatory authority shall issue
     an order suspending the qualification or exemption of any Securities under
     any 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.

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

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

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

                                       4

    Memorandum so that the statements therein as so amended or supplemented will
    not, in the light of the circumstances when it is so delivered, be
    misleading, or so that such Offering Memorandum will comply with applicable
    law.

     knowledge, no collective bargaining organizing activities are taking place
     with respect to the Company, the Subsidiaries or the Joint Ventures. None
     of the Company, any Subsidiary or any Joint Venture has violated (A) any
     federal, state or local law or foreign law relating to discrimination in
     hiring, promotion or pay of employees, (B) any applicable wage or hour laws

     1974, as amended ("ERISA"), or the rules and regulations thereunder, which
                        -----
     in the case of clause (A), (B) or (C) above could reasonably be expected to
     result in a Material Adverse Effect.

          (xxii) None of the Company, any Subsidiary or any Joint Venture has
     violated any environmental, safety or similar law or regulation applicable
     to it or its business or property relating to the protection of human
     health and safety, the environment or hazardous or toxic substances or
     wastes, pollutants or contaminants ("Environmental Laws"), lacks any

     violating any term or condition of such permit, license or approval which
     could reasonably be expected to, either individually or in the aggregate,

          (xxiii) Each of the Company, the Subsidiaries and the Joint Ventures
     has (i) good and marketable title to all of the properties and assets

     Memorandum or where failure to hold such Authorizations would not,
     individually or in the aggregate, have a Material Adverse Effect and (iv)
     no reason to believe that any governmental body or agency is considering
     limiting, suspending or revoking any such Authorization. Except where the
     failure to be in full force and effect would not have a Material Adverse
     Effect, all such Authorizations are valid and in full force and effect and
     each of the Company, the Subsidiaries and the Joint Ventures is in
     compliance with the terms and conditions of all such Authorizations and
     with the rules and regulations of the regulatory authorities having
     jurisdiction with respect thereto. All leases to which the Company, the

     default by the Company, any Subsidiary or any Joint Venture has occurred
     and is continuing thereunder and no defaults by the landlord are existing

     connection with the businesses now operated by it or which are proposed to
     be operated by the Company, its Subsidiaries or the Joint Ventures free and
     clear of and without violating any right, claimed right, charge,
     encumbrance, pledge, security interest, restriction or lien of any kind of
     any other person and none of the Company, any Subsidiary or any Joint
     Venture has received any notice of infringement of or conflict with
     asserted rights of others with respect to any of the foregoing except as
     could not reasonably be expected to have a Material Adverse Effect. The use
     of the Intellectual Property in connection with the business and operations
     of the Company, the Subsidiaries and the Joint Ventures does not infringe
     on the rights of any person, except would not have a Material Adverse
     Effect.

          (xxv) None of the Company, any Subsidiary, any Joint Venture or any of
     their respective officers, directors, partners, employees, agents or
     affiliates or any other person acting on behalf of the Company, any

     business) to any customer, supplier, employee or agent of a customer or
     supplier, official or employee of any governmental agency (domestic or
     foreign), instrumentality of any government (domestic or foreign) or any
     political party or candidate for office (domestic or foreign) or other
     person who was, is or may be in a position to help or hinder the business
     of the Company, any Subsidiary or any Joint Venture (or assist the

     Company, any Subsidiary or any Joint Venture in connection with any actual
     or proposed transaction) which (i) might subject the Company, any
     Subsidiary, or any other individual or entity to any damage or penalty in
     any civil, criminal or governmental litigation or proceeding (domestic or
     foreign), (ii) if not given in the past, could reasonably be expected to
     have had a Material Adverse Effect on the assets, business or operations of
     the Company, any Subsidiary or any Joint Venture or (iii) if not continued
     in the future, could reasonably be expected to have a Material Adverse
     Effect.

          (xxvi) All tax returns required to be filed by the Company, each of
     the Subsidiaries and each of the Joint Ventures in all jurisdictions have
     been so filed. All taxes, including withholding taxes, penalties and
     interest, assessments, fees and other charges due or claimed to be due from
     such entities or that are due and payable have been paid, other than those
     being contested in good faith and for which adequate reserves have been
     provided or those currently payable without penalty or interest. There are
     no proposed additional tax assessments against the Company, any Subsidiary,
     any Joint Venture or the assets or property of the Company, any Subsidiary
     or any Joint Venture.

          (xxvii) None of the Company, the Subsidiaries or the Joint Ventures is
     (i) an "investment company" or a company "controlled" by an "investment
     company" within the meaning of the Investment Company Act of 1940, as
     amended (the "Investment Company Act"), or (ii) a "holding company" or a
                   ----------------------
     "subsidiary company" or an "affiliate" of a holding company within the
     meaning of the Public Utility Holding Company Act of 1935, as amended (the
     "PUC Act"), except for TCG Pittsburgh, a New York general partnership ("TGC
     Pittsburgh").

          (xxviii) There are no holders of securities of the Company, the
     Subsidiaries or the Joint Ventures who, by reason of the execution by the
     Company of this Agreement or any other Operative Document to which it is a
     party or the consummation by the Company of the transactions contemplated
     hereby and thereby, have the right to request or demand that the Company,
     any of the Subsidiaries or any of the Joint Ventures register any of its
     securities under the Act.

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

          (xxx) Each of the Company, the Subsidiaries and the Joint Ventures
     maintains insurance covering its properties, operations, personnel and
     businesses. Such insurance insures against such losses and risks as are
     adequate in accordance with customary industry practice to protect the
     Company, the Subsidiaries, the Joint Ventures and their respective
     businesses. None of the Company, any Subsidiary or any Joint Venture has
     received notice from any insurer or agent of such insurer that substantial
     capital improvements or other expenditures will have to be made in order to
     continue such insurance. All such insurance is outstanding and duly in
     force on the date hereof.

          (xxxi) None of the Company, any Subsidiary or any Joint Venture has
     (i) taken, directly or indirectly, any action designed to, or that might
     reasonably be expected to, cause or result in

                                      13

     stabilization or manipulation of the price of any security of the Company
     to facilitate the sale or resale of the Units, the Senior Notes or the
     Warrants or (ii) since the date of the Preliminary Offering Memorandum (A)
     sold, bid for, purchased or paid any person any compensation for soliciting
     purchases of, the Units, the Senior Notes or the Warrants or (B) paid or
     agreed to pay to any person any compensation for soliciting another to
     purchase any other securities of the Company.

          (xxxii) No registration under the Act of the Units, the Senior Notes
     or the Warrants is required for the sale of the Units to the Initial
     Purchasers as contemplated hereby or for the Exempt Resales assuming (i)
     that the purchasers who buy the Units in the Exempt Resales are either QIBs
     or Accredited Investors and (ii) the accuracy of the Initial Purchasers'
     representations regarding the absence of general solicitation in connection
     with the sale of Units to the Initial Purchasers and the Exempt Resales
     contained herein. No form of general solicitation or general advertising
     was used by the Company or any of its representatives (other than the
     Initial Purchasers, as to which the Company makes no representation or
     warranty) in connection with the offer and sale of any of the Securities in
     connection with Exempt Resales, including, but not limited to, articles,
     notices or other communications published in any newspaper, magazine, or
     similar medium or broadcast over television or radio, or any seminar or
     meeting whose attendees have been invited by any general solicitation or
     general advertising. No securities of the same class as the Securities have
     been issued and sold by the Company within the six-month period immediately
     prior to the date hereof.

          (xxxiii) Set forth on Exhibit C hereto is a list of each employee
                                ---------
     pension or benefit plan with respect to which the Company or any
     corporation considered an affiliate of the Company within the meaning of
     Section 407(d)(7) of ERISA (an "ERISA Affiliate") is a party in interest or
                                     ---------------
     disqualified person. The execution and delivery of this Agreement, the
     other Operative Documents and the sale of the Units to be purchased by the
     QIBs and the Accredited Investors will not involve any prohibited
     transaction within the meaning of Section 406 of ERISA or Section 4975 of
     the Internal Revenue Code of 1986. The representation made by the Company
     in the preceding sentence is made in reliance upon and subject to the
     accuracy of, and compliance with, the representations and covenants made or
     deemed made by the QIBs and the Accredited Investors as set forth in the
     Offering Memorandum under the caption "Notice to Investors."

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

          (xxxv) Subsequent to the respective dates as of which information is
     given in the Offering Memorandum and up to the Closing Date, except as set
     forth in the Offering Memorandum, (i) none of the Company, any Subsidiary
     or any Joint Venture has incurred any liabilities or obligations, direct or
     contingent, which are material, individually or in the aggregate, to the
     Company, the Subsidiaries and the Joint Ventures taken as a whole, nor
     entered into any transaction not in the ordinary course of business, (ii)
     there has not been, singly or in the aggregate, any change or development
     which could reasonably be expected to result in a Material Adverse Effect,
     (iii) there has been no dividend or distribution of any kind declared, paid
     or made by the Company or its Subsidiaries on any class of capital stock
     and (iv) there has been no distribution of profits or return of capital
     contribution by any Joint Venture.

          (xxxvi) None of the execution, delivery and performance of this
     Agreement, the issuance and sale of the Securities, the application of the
     proceeds from the issuance and sale of the Securities and the consummation
     of the transactions contemplated thereby as set forth in the

                                      14
<PAGE>
 
     Offering Memorandum, will violate Regulations G, T, U or X promulgated by
     the Board of Governors of the Federal Reserve System or analogous foreign
     laws and regulations.

          (xxxvii) The accountants who have certified or will certify the
     financial statements included or to be included as part of the Offering
     Memorandum are independent accountants. The historical financial statements
     of the Company and each of the Subsidiaries comply as to form in all
     material respects with the requirements applicable to registration
     statements on Form S-4 under the Act and present fairly in all material
     respects the financial position and results of operations of the Company
     and each of its Subsidiaries, at the respective dates and for the
     respective periods indicated. Such financial statements have been prepared
     in accordance with generally accepted accounting principles applied on a
     consistent basis throughout the periods presented. The other financial
     information and data included in the Offering Memorandum, historical and
     pro forma, are accurately presented in all material respects and prepared
     on a basis consistent with the financial statements, historical and pro
     forma, included in the Offering Memorandum and the books and records of the
     Company, each of its Subsidiaries and each of its Joint Ventures, as
     applicable. The statistical information and data included in the Offering
     Memorandum are accurately presented in all material respects.

          (xxxviii) The Company does not intend to, nor does it believe that it
     will, incur debts beyond its ability to pay such debts as they mature. The
     present fair saleable value of the assets of the Company on a consolidated
     basis exceeds the amount that will be required to be paid on or in respect
     of the existing debts and other liabilities (including contingent
     liabilities) of the Company on a consolidated basis as they become absolute
     and matured. The assets of the Company on a consolidated basis do not
     constitute unreasonably small capital to carry out the business of the
     Company, the Subsidiaries and the Joint Ventures, taken as a whole, as
     conducted or as proposed to be conducted. Upon the issuance of the Units,
     the present fair saleable value of the assets of the Company on a
     consolidated basis will exceed the amount that will be required to be paid
     on or in respect of the existing debts and other liabilities (including
     contingent liabilities) of the Company on a consolidated basis as they
     become absolute and matured. Upon the issuance of the Units, the assets of
     the Company on a consolidated basis will not constitute unreasonably small
     capital to carry out its businesses as now conducted, including the capital
     needs of the Company on a consolidated basis, taking into account the
     projected capital requirements and capital availability.

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

          (xl) Each of the Company, the Subsidiaries and the Joint Ventures has
     complied with all provisions of Section 517.075, Florida Statutes, relating
     to doing business with the Government of Cuba or with any affiliate located
     in Cuba.

          (xli) Except as disclosed in the Offering Memorandum, there are no
     business relationships or related party transactions required to be
     disclosed therein pursuant to Item 404 of Regulation S-K of the Commission
     (assuming for purposes of this paragraph 5(xli) that Regulation S-K is
     applicable to the Offering Memorandum).

          (xlii) Each of the Company and Hyperion Telecommunications of
     Pennsylvania, Inc. will be released from all of their obligations under the
     agreement governing the TCG Pittsburgh Joint

                                      15

     Venture pursuant to an amendment to such partnership agreement to be
     effective as of January 1, 1995, which amendment shall be promptly
     executed.

          Each certificate signed by any officer of the Company and delivered to
the Initial Purchasers or counsel for the Initial Purchasers pursuant to this
Agreement shall be deemed to be a representation and warranty by the Company to
the Initial Purchasers as to the matters covered thereby.

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

     (b) Each of the Initial Purchasers severally and not jointly represents,
warrants and covenants to the Company and agrees that:

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

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

          (iii) No form of general solicitation or general advertising has been
     or will be used by any of the Initial Purchasers or any of their
     representatives in connection with the offer and sale of any of the Units,
     including, but not limited to, articles, notices or other communications
     published in any newspaper, magazine, or similar medium or broadcast over
     television or radio, or any seminar or meeting whose attendees have been
     invited by any general solicitation or general advertising.

          (iv) In connection with the Exempt Resales, such Initial Purchaser
     will solicit offers to buy the Units only from, and will offer to sell the
     Units only to, QIBs and Accredited Investors. Such Initial Purchaser
     further agreed (A) that it will offer to sell the Units only to, and will
     solicit offers to buy the Units only from (1) QIB's who in purchasing such
     Units will be deemed to have represented and agreed that they are
     purchasing the Units for their own accounts or accounts with respect to
     which they exercise sole investment discretion and that they or such
     accounts are QIBs and (2) Accredited Investors who make the representations
     contained in, and execute and return to one of the Initial Purchasers, a
     certificate in the form of Annex A attached to the Offering Memorandum and
                                -------
     (B) that, in the case of such QIBs and Accredited Investors, acknowledges
     and agrees that such Units will not have been registered under the Act and
     may be resold, pledged or otherwise transferred only (x)(I) to a person who
     the seller reasonably believes is a QIB in a transaction meeting the
     requirements of Rule 144A or (II) in a transaction meeting the requirements
     of Rule 144 or (III) in accordance with another exemption from the
     registration requirements of the Act (and based upon an opinion of counsel
     if the Company so requests), (y) to the Company or (z) pursuant to an
     effective registration statement under the Act and, in each case, in
     accordance with any applicable securities laws of any state of the United
     States or any other applicable jurisdiction and (C) that the holder will,
     and each subsequent holder is required to, notify any purchaser of the
     security evidenced thereby of the resale restrictions set forth in (B)
     above.

                                      16

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

     6.   Indemnification.
          ---------------

          (a) The Company and its Subsidiaries, jointly and severally, agree to
     indemnify and hold harmless (i) each Initial Purchaser, (ii) each person,
     if any, who controls an Initial Purchaser 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
     Initial Purchaser or any controlling person to the fullest extent lawful,
     from and against any and all losses, liabilities, claims, damages and
     expenses whatsoever (including but not limited to attorneys' fees and any
     and all expenses whatsoever incurred in investigating, preparing or
     defending against any investigation or litigation, commenced or threatened,
     or any claim whatsoever, and any and all amounts paid in settlement of any
     claim or litigation), joint or several, to which they or any of them may
     become subject under the Act, the Exchange Act or otherwise, insofar as
     such losses, liabilities, claims, damages or expenses (or actions in
     respect thereof) arise out of or are based upon any untrue statement or
     alleged untrue statement of a material fact contained in the Preliminary
     Offering Memorandum or the Offering Memorandum, or in any supplement
     thereto or amendment thereof, or arise out of or are based upon the
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading; provided
     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 the Initial Purchasers expressly for use therein and (ii)
     the foregoing indemnity with respect to any untrue statement contained in
     or omitted from the Preliminary Offering Memorandum shall not inure to the
     benefit of any Initial Purchaser (or any person controlling such Initial
     Purchasers), from whom the person asserting any such loss, liability,
     claim, damage or expense purchased any of the Units 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 such Initial
     Purchaser sold Units to the person asserting such loss, liability, claim,
     damage or expense, who was not sent or given, at or prior to the written
     confirmation of such sale, a copy of the Offering Memorandum, as amended or
     supplemented, and (x) the Company shall have previously and timely
     furnished sufficient copies of the Offering Memorandum, as so amended or
     supplemented, to such Initial Purchaser in accordance with this Agreement
     and (y) the Offering Memorandum, as so amended or supplemented, would have
     completely 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 Initial Purchaser, 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


                                      17
<PAGE>
 
     statement or alleged untrue statement of a material fact contained in the
     Preliminary Offering Memorandum or the Offering Memorandum, or in any
     amendment thereof or supplement thereto, or arise out of or are based upon
     the omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading, in
     each case to the extent, but only to the extent, that any such loss,
     liability, claim, damage or expense arises out of or is based upon any
     untrue statement or alleged untrue statement or omission or alleged
     omission made therein in reliance upon and in conformity with written
     information furnished to the Company by or on behalf of any Initial
     Purchaser expressly for use therein; provided that in no case shall any
     Initial Purchaser be liable or responsible for any amount in excess of the
     discounts and commissions received by such Initial Purchasers, as set forth
     on the cover page of the Offering Memorandum. This indemnity will be in
     addition to any liability which any of the Initial Purchasers may otherwise
     have, including under this Agreement.

          (c) Promptly after receipt by an indemnified party under subsection
     (a) or (b) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under such subsection, notify each party
     against whom indemnification is to be sought in writing of the commencement
     thereof (but the failure so to notify an indemnifying party shall not
     relieve it from any liability which it may have under this Section 6 except
     to the extent that it has been actually 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. 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; provided that the
     indemnifying party shall be liable for separate counsel for any indemnified
     party in a jurisdiction, if counsel to the indemnified parties shall have
     reasonably concluded that there may be defenses available to such
     indemnified party that are difference from or additional to those available
     to one or more of the other indemnified parties and that separate counsel
     for such indemnified party is prudent under the circumstances. Anything in
     this subsection to the contrary notwithstanding, an indemnifying party
     shall not be liable for any settlement of any claim or action effected
     without its prior written consent; provided that such consent was not
     unreasonably withheld.

     7. Contribution. In order to provide for contribution in circumstances in
        ------------
which the indemnification provided for in Section 6 is for any reason held to be
unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company and the Initial Purchasers shall contribute
to the aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated

                                      18
<PAGE>
 
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
Initial Purchasers, 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 one or more of the Initial
Purchasers may be subject, in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Initial Purchasers from the
offering of the Units or, if such allocation is not permitted by applicable law
or indemnification is not available as a result of the indemnifying party not
having received notice as provided in Section 6, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Initial Purchasers 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 the Initial Purchasers shall
be deemed to be in the same proportion as (x) the total proceeds from the
offering of Units (net of discounts but before deducting expenses) received by
the Company and (y) the discounts received by the Initial Purchasers,
respectively, in each case as set forth in the table on the cover page of the
Offering Memorandum. The relative fault of the Company and of the Initial
Purchasers shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Initial Purchasers and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to above. Notwithstanding the provisions
of this Section 7, (i) in no case shall any Initial Purchaser be required to
contribute any amount in excess of the amount by which the discount applicable
to the Units purchased by such Initial Purchaser pursuant to this Agreement
exceeds the amount of any damages which such Initial Purchaser has otherwise
been required to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 7, (A) each person, if any, who
controls any Initial Purchaser 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 any Initial Purchaser or any
controlling person shall have the same rights to contribution as such Initial
Purchaser, 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 7. Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made
against another party or parties under this Section 7, notify such party or
parties from whom contribution may be sought, but the failure to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any obligation it or they may have under this Section 7 or
otherwise. No party shall be liable for contribution with respect to any action
or claim settled without its prior written consent; provided that such written
consent was not unreasonably withheld.

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

     notes thereto included in the Offering Memorandum. Since the date hereof

     of Section 11(b), in which case each party will be responsible for its own
     expenses), or if the sale of the Units provided for herein is not
     consummated because any condition to the obligations of the Initial
     Purchasers set forth herein is not satisfied or because of any refusal,

     herein or comply with any provision hereof, the Company will, subject to
     demand by the Initial Purchasers, reimburse the Initial Purchasers for all
     out-of-pocket expenses (including the reasonable fees and expenses of

jurisdiction of incorporation, and has all requisite corporate power and
authority to carry on its business as it is being conducted and as described in
the Offering Memorandum and to own, lease and operate its properties, and is
duly qualified and in good standing as a foreign corporation authorized to do
business in each jurisdiction in which the nature of its business or its
ownership or leasing of property requires such qualification, except where the
failure to be so qualified would not, singly or in the aggregate, have a
material adverse effect on the business, financial condition or results of
operations of the Company, the Subsidiaries and the Joint Ventures, taken as a
whole.

    2. Each of the Joint Ventures is duly formed and valid existing as a general
partnership in good standing under the laws of its jurisdiction of formation,

lease and operate its properties, and is duly qualified and in good standing as
a partnership authorized to do business in each jurisdiction in which the nature
of its business or its ownership or leasing of property requires such

the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other similar laws now or hereafter in effect relating to or
affecting creditors' rights and remedies generally, (b) by the effects of
general principals of equity, whether enforcement is considered in a proceeding
in equity or at law, and the discretion of the court before which any proceeding

Agreement and, when issued and authenticated in accordance with the terms of the

contained in the Preliminary Offering Memorandum or the Offering Memorandum

          ----------------                                                     
of the parties with reference to the matters set forth herein.  This Agreement
supersedes all prior negotiations, discussions, correspondence, communications
and prior agreements among the parties relating to the subject matter herein.

     7.5  Amendment and Waiver.  This Agreement may not be amended or modified
          --------------------                                                
in any respect except by an instrument in writing signed by each party.  Any
failure of either party to comply with any obligation, covenant, agreement or
condition contained herein may be waived by the other party, but such waiver or

                                      -8-
<PAGE>
 
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent breach or other failure.

     7.6  Governing Law.  This Agreement shall be governed by, and construed in
          -------------                                                        
accordance with, the laws of the State of New York (without regard to its laws
pertaining to conflicts of law) applicable to contracts executed in and to be
performed entirely in such state.

     7.7  Severability.  If any term or other provision of this Agreement is
          ------------                                                      
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transaction contemplated hereby is not affected in any manner adverse to
either party.  Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that the transaction contemplated hereby are fulfilled to the greatest extent
possible.

     7.8  Consent to Jurisdiction; Specific Performance.  Each party hereby
          ---------------------------------------------                    
irrevocably submits to the non-exclusive jurisdiction of any New York State or
Federal court in any action or proceeding arising out of or relating to this
Agreement, and each party hereby irrevocably agrees that all claims in respect
of such action or proceeding may be heard and determined in such New York State
or Federal court.  Each party hereby irrevocably waives, to the fullest extent
it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding.  Nothing in this Section 7.8 shall
affect the right of either party to serve legal process in any other manner
permitted by law or affect the right of either party to bring any action or
proceeding against the other party or its property in the courts of any other
jurisdictions.  The consents to jurisdiction set forth in this Section 7.8 shall
not constitute general consents to service of process in the State of New York,
shall have no effect for any purpose except as provided in this Section 7.8 and
shall not be deemed to confer rights on any Person other than the parties to
this Agreement.  Without intending to limit the remedies available to either
party, each party acknowledges and agrees that a violation by such party of any
term of this Agreement will cause the other party irreparable injury for which
an adequate remedy at law is not available.  Therefore, the parties agree that
each party shall be entitled to an injunction, restraining order or other form
of equitable relief from any court of competent jurisdiction restraining the
other party from committing any breach or threatened breach of, or otherwise
specifically to enforce, any provision of this Agreement.

     7.9  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall be an original, but all of which taken
together shall constitute one and the same agreement.

     7.10  Headings.  The section headings used in this Agreement are for
           --------                                                      
reference purposes only and shall not affect the meaning or interpretation of
any term or provision of this Agreement.

authorize a class or series of stock having such terms, and until such approval
shall have been obtained the class or any such series of Preferred Stock shall
not be deemed to be authorized.  The Board of Directors may in its discretion,
at any time or from time to time, issue or cause to be issued all or any part of

shall be held at such time and place as shall be fixed by the vote of the
stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event of the failure of the

the meeting, until a quorum shall be present.

     Section 9.  Unless otherwise restricted by the certificate of incorporation
or these by-laws, any action required or permitted to be taken at any meeting of
the board of directors or of any committee thereof may be taken without a
meeting, if all members of the board or committee, as the case may be, consent

or more directors as alternate members of any committee, who may replace any
absent or disqualified member at any meeting of the committee. In the absence or

member. Any such committee, to the extent provided in the resolution of the
board of directors, shall have and may exercise all the powers and authority of

agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the by-laws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock. Such committee or committees shall have such
name or names as may be determined from time to time by resolution adopted by
the board of directors.

     Section 11.  Each committee shall keep regular minutes of its meetings and
report the same to the board of directors when required.

director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

or completed claim, action, suit or proceeding which is initiated by him.

     Section 2.  The indemnification provided or permitted by Section 1 shall
apply (i) whether or not the director, officer, employee or representative
continues to be such at the time such liabilities or expenses are imposed or
incurred, whether the act or failure to act which is the subject of such claim,
action, suit or proceeding occurred before or after the adoption of this by-law,
and whether or not the indemnified liability or expenses arose or arise from a
threatened, pending or completed claim, action, suit or proceeding by or in the
right of the corporation, and (ii) both to acts or omissions in his official
capacity and to acts or omissions in another capacity while holding such office.

     Section 3.  Expenses incurred by a director, officer, employee or
representative of the corporation in defending a civil or criminal action, suit
or proceeding may be paid by the corporation in advance of the final disposition
thereof upon receipt of an undertaking by or on behalf of such person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation.

     Section 4.  The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article VI shall not be exclusive of any other rights
to which persons seeking indemnification or advancement of expenses may be
entitled under any provision of law, agreement, vote of shareholders or
directors or otherwise, both as to an act or omission in his official capacity
and as to an act or omission in another capacity while holding such office, and
shall inure to the benefit of the heirs, executors, administrators and other
legal representatives of such person.

     Section 5.  The corporation may purchase and maintain insurance on behalf
of any person who is or was a director, officer, employee or representative of
the corporation or who is or was serving at the request of the corporation as a
director, officer, employee or other representative of another corporation,
partnership, joint venture, trust or other enterprise, for any liability
asserted against such director, officer, employee or representative and incurred
by him in any capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against such liability under
the laws of the State of Delaware.

                             CERTIFICATES OF STOCK

     Section 1.  Every holder of stock in the corporation shall be entitled to
have a certificate, signed by, or in the name of the corporation by, the
chairman or vice-chairman of the board of directors or the president or a vice-

     Certificates may be issued for partly paid shares and in such case upon the
face or back of the certificates issued to represent any such partly paid
shares, the total amount of the consideration to be paid therefor, and the
amount paid thereon shall be specified.

     Section 2.  Any of or all the signatures on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the corporation with the same effect if as he were
such officer, transfer agent or registrar at the date of issue.

                               LOST CERTIFICATES

     Section 3.  The board of directors may direct a new certificate or
certificates to be issued in place of any certificate or certificates
theretofore issued by the corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the board of directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

                               TRANSFERS OF STOCK

     Section 4.  Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

                               FIXING RECORD DATE

     Section 5.  In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the board of directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the board of directors may fix a new record date for the adjourned
meeting.

Section 2.01.  Form and Dating.

    The Senior Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto.  The Senior Notes may have
                             ---------                                   
notations, legends or endorsements required by law, stock exchange rule or
usage.  Each Senior Note shall be dated the date of its authentication.  The
Senior Notes shall be in denominations of $1,000 and integral multiples thereof.

    The terms and provisions contained in the Senior Notes 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.

    Senior Notes 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).  Senior Notes issued in the form of registered definitive certificates
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 Note
shall represent such of the outstanding Senior Notes as shall be specified
therein and each shall provide that it shall represent the aggregate amount of
outstanding Senior Notes from time to time endorsed thereon and that the
aggregate amount of outstanding Senior Notes represented thereby may from time
to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions.  Any endorsement of a Global Note to reflect the amount of any
increase or decrease in the amount of outstanding Senior Notes represented
thereby shall be made by the Trustee or the Senior Note 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 shall sign the Senior Notes for the Company by manual or
facsimile signature.  The Company's seal shall be reproduced on the Senior Notes
and may be in facsimile form.

    If an Officer whose signature is on a Senior Note no longer holds that
office at the time a Senior Note is authenticated, the Senior Note shall
nevertheless be valid.
<PAGE>
 
    A Senior Note shall not be valid until authenticated by the manual signature
of the Trustee.  The signature shall be conclusive evidence that the Senior Note
has been authenticated under this Indenture.

    The Trustee shall, upon a written order of the Company signed by two
Officers, authenticate Senior Notes for original issue up to the aggregate
principal amount stated in paragraph 4 of the Senior Notes.  The aggregate
principal amount of Senior Notes 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 Senior Notes.  An authenticating agent may authenticate Senior
Notes whenever the Trustee may do so.  Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.  An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

Section 2.03.  Registrar and Paying Agent.

    The Company shall maintain (i) an office or agency where Senior Notes may be
presented for registration of transfer or for exchange ("Registrar") and (ii) an
office or agency where Senior Notes may be presented for payment ("Paying
Agent").  The Registrar shall keep a register of the Senior Notes 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 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 initially appoints The Depository Trust Company ("DTC") to act

Paying Agent and to act as Senior Note Custodian with respect to the Global

in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal,
premium or Liquidated Damages, if any, or interest on the Senior Notes, and will
notify the Trustee of any default by the Company in making any such 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
<PAGE>
 
trust fund for the benefit of the Holders all money held by it as Paying Agent.
Upon any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Senior Notes.

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 (S) 312(a).  If the Trustee is not the
Registrar, the Company shall furnish to the Trustee at least seven 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 as of such date as the Trustee may
reasonably require of the names and addresses of the Holders of Senior Notes and

                 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 Series B Senior Notes in exchange for
             Series A Senior 
<PAGE>
 
             Notes accepted for exchange in the Exchange Offer, which Series B
             Senior Notes shall not bear the first legend set forth in (i)
             above, and the Registrar shall rescind any restriction on the
             transfer of such Senior Notes, in each case unless the Holder of
             such Series A Senior Notes is either (A) a broker-dealer, (B) a
             Person participating in the distribution of the Series A Senior
             Notes or (C) a Person who is an affiliate (as defined in Rule 144A)
             of the Company.

    (h) Cancellation and/or Adjustment of a Global Note.  At such time as all
beneficial interests in a Global Note have been exchanged for Definitive Senior
Notes, redeemed, repurchased or cancelled, such Global Note shall be returned to
or retained and cancelled by the Trustee in accordance with Section 2.11 hereof.
At any time prior to such cancellation, if any beneficial interest in a Global
Note is exchanged for Definitive Senior Notes, redeemed, repurchased or
cancelled, the principal amount of Senior Notes represented by such Global Note
shall be reduced accordingly and an endorsement shall be made on such Global
Note, by the Trustee or the Senior Notes 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 Senior
             Notes and Global Notes 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) The Registrar shall not be required to register the transfer of or
             exchange any Senior Note selected for redemption in whole or in
             part, except the unredeemed portion of any Senior Note being
             redeemed in part.

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

         (v) The Company shall not be required:

             (A) to issue, to register the transfer of or to exchange Senior
                 Notes during a period beginning at the opening of business 15
                 days before the day of any selection of Senior Notes for
<PAGE>
 
                 redemption under Section 3.02 hereof and ending at the close of
                 business on the day of selection; or

             (B) to register the transfer of or to exchange any Senior Note so
                 selected for redemption in whole or in part, except the
                 unredeemed portion of any Senior Note being redeemed in part;
                 or

             (C) to register the transfer of or to exchange a Senior Note
                 between a record date and the next succeeding interest payment
                 date.

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

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

    (j) The Senior Notes and the Warrants will not be separately exchangeable or
        transferable prior to the Separation Date, at which time the Senior
        Notes shall become separately exchangeable and transferable. Prior to
        the Separation Date, Senior Notes will be exchangeable and transferable
        only together with the Warrants related thereto as set forth herein and
        in the Warrant Agreement.


Section 2.07.  Replacement Senior Notes.

    If any mutilated Senior Note is surrendered to the Trustee, or the Company
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Senior Note, the Company shall issue and the Trustee, upon the
written order of the Company signed by two Officers of the Company, shall
authenticate a replacement Senior Note 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 Senior Note is replaced.  The Company
may charge for its expenses in replacing a Senior Note.

    Every replacement Senior Note 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 Senior Notes duly issued hereunder.
<PAGE>
 
Section 2.08.  Outstanding Senior Notes.

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

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

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

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

Section 2.09.  Treasury Senior Notes.

    In determining whether the Holders of the required principal amount of
Senior Notes have concurred in any direction, waiver or consent, Senior Notes
owned by the Company, or by any Affiliate thereof 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
Senior Notes that a Trustee knows are so owned shall be so disregarded.

Section 2.10.  Temporary Senior Notes.

    Until definitive Senior Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Senior Notes upon a written
order of the Company signed by two Officers of the Company.  Temporary Senior
Notes shall be substantially in the form of definitive Senior Notes but may have
variations that the Company considers appropriate for temporary Senior Notes and
as shall be reasonably acceptable to the Trustee.  Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive Senior
Notes in exchange for temporary Senior Notes.

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

Section 2.11.  Cancellation.

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

Section 2.12.  Record Date.

    The record date for purposes of determining the identity of Holders of the
Senior Notes 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 (S) 316 (c).

Section 2.13.  Defaulted Interest.

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

                           REDEMPTION AND PREPAYMENT

Section 3.01.  Notices to Trustee.

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

Section 3.02.  Selection of Senior Notes to Be Redeemed.

    If less than all of the Senior Notes are to be redeemed at any time, the
Trustee shall select the Senior Notes to be redeemed among the Holders of the
Senior Notes in compliance with the requirements of the principal national
securities exchange, if any, on which the Senior Notes are listed or, if the
Senior Notes are not so listed, on a pro
<PAGE>
 
rata basis, by lot or in accordance with any other method the Trustee considers
fair and appropriate. In the event of partial redemption by lot, the particular
Senior Notes to be redeemed shall be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption date by the
Trustee from the outstanding Senior Notes not previously called for redemption.

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

Section 3.03.  Notice of Redemption.

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

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

    (a)  the redemption date;

    (b)  the redemption price;

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

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

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

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

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

    (h) that no representation is made as to the correctness or accuracy of
the CUSIP number, if any, listed in such notice or printed on the Senior
Notes.
<PAGE>
 
    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,
Senior Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price.  A notice of redemption may not be
conditional.

Section 3.05.  Deposit of Redemption Price.

    One Business Day prior to the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Senior Notes to be redeemed on that date.
The Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, accrued interest on and
Liquidated Damages, if any, all Senior Notes 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 Senior
Notes or the portions of Senior Notes called for redemption.  If a Senior Note
is redeemed on or after an interest record date but on or prior to the related
interest payment date, then any accrued and unpaid interest and Liquidated
Damages, if any, shall be paid to the Person in whose name such Senior Note was
registered at the close of business on such record date.  If any Senior Note
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 Senior Notes and in
Section 4.01 hereof.

Section 3.06.  Senior Notes Redeemed in Part.

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

Section 3.07.  Optional Redemption.

    (a)  Except as set forth in clause (b) of this Section 3.07, the Company
shall not have the option to redeem the Senior Notes prior to April 15, 2001.
Thereafter, the Company shall have the option to redeem the Senior Notes, in
whole or in part, upon not less than 30 nor more than 60 days notice, at the
redemption prices (expressed as
<PAGE>
 
percentages of principal amount, of, if such redemption occurs prior to April
15, 2001, the Accreted Value) set forth below plus accrued and unpaid interest
thereon and Liquidated Damages, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on April 15 of the years
indicated below:

</TABLE> 

    (b)  Notwithstanding the foregoing, the Company, on or prior to April 15,
1999, may redeem up to a maximum of 25% of the aggregate principal amount of the
Senior Notes then outstanding at a redemption price of 113.0% of the Accreted
Value thereof, with the net proceeds from either (i) an Initial Public Offering
of the common stock of the Company or (ii) a sale of the Capital Stock (other
than Disqualified Stock) of the Company to a Strategic Investor in a single
transaction or a series of related transactions for at least $25.0 million;
provided that, in either case, at least 75% in aggregate principal amount of the
Senior Notes remain outstanding immediately after the occurrence of such
redemption; and provided, further, that such redemption shall occur within 90
days of the date of the closing of such Initial Public Offering or such sale to
a Strategic Investor, as the case may be.

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

Section 3.08.  Mandatory Redemption.

    Except as set forth under Sections 4.10 and 4.15 hereof, the Company shall
not be required to make mandatory redemption or sinking fund payments with
respect to the Senior Notes.

Section 3.09.  Offer to Purchase by Application of Excess Proceeds.

    In the event that, pursuant to Section 4.10 hereof, the Company shall be
required to commence an offer to all Holders to purchase Senior Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

    The Asset Sale 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 principal amount of Senior Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Senior Notes tendered in response to the
Asset Sale Offer.  Payment for any Senior Notes so purchased shall be made in
the same manner as interest payments are made.
<PAGE>
 
    The Company shall comply with any tender offer rules under the Exchange Act
which may then be applicable, including Rule 14e-1, in connection with any offer
required to be made by the Company to repurchase the Senior Notes as a result of
an Asset Sale Offer.  To the extent that the provisions of any securities laws
or regulations conflict with provisions of this Section 3.09, the Company shall
comply with the applicable securities laws or regulations and shall not be
deemed to have breached its obligations hereunder by virtue thereof.

    If the Purchase Date is on or after an interest record date and on or before
the related interest payment date, any accrued and unpaid interest shall be paid
to the Person in whose name a Senior Note is registered at the close of business
on such record date, and no additional interest shall be payable to Holders who
tender Senior Notes pursuant to the Asset Sale Offer.

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

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

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

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

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

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

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

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

          (h) that, if the aggregate principal amount of Senior Notes
surrendered by Holders exceeds the Offer Amount, the Company shall select the
Senior Notes to be purchased on a pro rata basis (with such adjustments as may
be deemed appropriate by the Company so that only Senior Notes in denominations
of $1,000, or integral multiples thereof, shall be purchased); and

          (i) that Holders whose Senior Notes were purchased only in part shall
be issued new Senior Notes equal in principal amount to the unpurchased portion
of the Senior Notes 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 to the extent necessary, the Offer
Amount of Senior Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Senior Notes
tendered, and shall deliver to the Trustee an Officers' Certificate stating that
such Senior Notes or portions thereof were accepted for payment by the Company
in accordance with the terms of this Section 3.09.  The Company, the Depository
or the Paying Agent, as the case may be, shall promptly (but in any case not
later than five days after the Purchase Date) mail or deliver to each tendering
Holder an amount equal to the purchase price of the Senior Notes tendered by
such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Senior Note, and the Trustee, upon written request from the
Company shall authenticate and mail or deliver such new Senior Note to such
Holder, in a principal amount equal to any unpurchased portion of the Senior
Note surrendered.  Any Senior Note 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 Asset Sale Offer on the Purchase Date.

    Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

    The Company shall pay or cause to be paid the principal of, premium, if any,
and interest on the Senior Notes (including any additional interest required to
be paid pursuant to the provisions of the Registration Rights Agreement) on the

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

    (a) The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Company, its Subsidiaries and Joint Ventures during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled
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 (or, if a Default or Event of Default shall have occurred, describing
all such Defaults or Events of Default of which he or she may have knowledge and
what action the Company is taking or proposes to take with respect thereto) and
that to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest, if any, on the Senior Notes is prohibited or if such event has
occurred, a description of the event and what action the Company is taking or
proposes to take with respect thereto.

    (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(a) 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 that would lead them to believe that the Company has violated
any provisions of Article Four or Article Five hereof or, if any such violation
has occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

    (c) The Company shall, so long as any of the Senior Notes are outstanding,
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

Section 4.05.  Taxes.

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

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 or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the 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
been enacted.

Section 4.07.  Restricted Payments.

    The Company shall not, and (i) shall not permit any of its Subsidiaries or
Joint Ventures to, directly or indirectly:  (a) declare or pay any dividend or
make any other payment or distribution on account of the Company's Equity
Interests (other than dividends or distributions payable in Equity Interests
(other than Disqualified Stock) of the Company or dividends or distributions
payable to the Company or any Wholly Owned Subsidiary); (b) purchase, redeem or
otherwise acquire or retire for value any Equity Interests of the Company or any
direct or indirect parent of the Company (other than Equity Interests owned by
the Company or any Wholly Owned Subsidiary of the Company); or (c) purchase,
redeem or otherwise acquire or retire for value, prior to a scheduled mandatory
sinking fund payment date or maturity date, any Indebtedness of the Company
which ranks subordinated in right to payment to the Senior Notes and (ii) shall
not permit any of its Subsidiaries or Permitted Joint Ventures to, make any
Investment other than a Permitted Investment (all such payments and other
actions set forth in clauses (i) and (ii) above being collectively referred to
as "Restricted Payments") unless, at the time of and after giving effect to such
Restricted Payment:

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

        (y) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments (including, without limitation, all Restricted
Payments referred to in clauses (a), (b) and (c)(1) below but excluding those
made under clauses (c)(2), (d) and (e) below) made by the Company and its
Subsidiaries after the date of the Indenture is less than the sum of: (1) the
excess of (A) Cumulative Pro Forma EBITDA over (B) 2.0 times Cumulative Interest
Expense plus (2) the aggregate net cash proceeds received by the Company (other
than from a Subsidiary or Joint Venture) (A) as capital contributions to the
Company, (B) from the issuance and sale of Equity Interest, other than
Disqualified Stock, and (C) from the issuance and sale of Indebtedness that is
convertible into Capital Stock (other than Disqualified Stock), to the extent
such Indebtedness is actually converted into such Capital Stock (clauses (A),
(B) and (C) collectively referred to as "Equity Issuances"), other than any such
net cash proceeds from Equity Issuances that were used as set forth in clause
(c) and (d) below; and
<PAGE>
 
        (z) the Company would, at the time of such Restricted Payment and after
giving pro forma effect thereto as if such Restricted Payment had been made at
the beginning of the applicable four-quarter period, have been permitted to
incur at least $1.00 of additional Indebtedness other than Permitted
Indebtedness.

    The foregoing provisions shall not prohibit:

       (a) the payment of any Required Capital Contribution;

       (b) the payment of any dividend within 60 days after the date of
           declaration thereof, if at said date of declaration such payment
           would have complied with this Section 4.07;

       (c) so long as no Default or Event of Default shall have occurred and be
           continuing, Restricted Joint Venture Investments, which at the time
           any such Restricted Joint Venture Investment was made, did not cause
           the aggregate amount of all Restricted Joint Venture Investments made
           on or after the date of this Indenture and then outstanding under
           this clause (c) to exceed (1) $20.0 million plus (2) the net cash
           proceeds from Equity Issuances not used as set forth in clause (y)
           above and clause (d) below;

       (d) so long as no Default or Event of Default shall have occurred and be
           continuing, the making of any Investment in a Telecommunications
           Business out of the net cash proceeds from Equity Issuances not used
           as set forth in clauses (y) and (c)(2) above; or

       (e) so long as no Default or Event of Default shall have occurred and be
           continuing, the making of loans and advances to the senior management
           of the Company in an amount not to exceed $3.0 million in aggregate
           principal amount.

       (f) all payments pursuant to the Athird sentence of Section 15 of the
           Warrant Agreement, dated April 15, 1996, between the Company and the
           Bank of Montreal Trust Company, as Warrant Agent.

    For purposes of this Section 4.07, in the event that a Restricted Joint
Venture becomes a Permitted Joint Venture or otherwise ceases to be a Restricted
Joint Venture, all of the then outstanding Investments made by such entity since
the date of the Indenture shall be deemed to have been made as of the date that
such Restricted Joint Venture becomes a Permitted Joint Venture or otherwise
ceases to be a Restricted Joint Venture; provided that if a Restricted Joint
Venture ceases to be a Restricted Joint Venture as a result of (i) the loss of
its Local Partner or (ii) the loss of management control of such Restricted
Joint Venture, then the provisions of this paragraph shall not be applied to
such entity.

    The amount of all Restricted Payments, other than cash, shall be the fair
market value (evidenced by a resolution of the Board of Directors set forth in
an Officers' Certificate delivered to the Trustee) on the date of such
Restricted Payment of the asset(s) proposed to be transferred by the Company or
such Subsidiary, as the case may
<PAGE>
 
be, pursuant to such Restricted Payment. Not later than the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this Section 4.07 were
computed, which calculations may be based upon the Company's latest available
financial statements.


Section 4.08.  Dividend and Other Payment Restrictions Affecting Subsidiaries.

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

        (i)   (a) pay dividends or make any other distributions to the Company
              or any of its Subsidiaries (1) on its Capital Stock or (2) with
              respect to any other interest or participation in, or measured by,
              its profits, or (b) pay any indebtedness owed to the Company or
              any of its Subsidiaries;

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

        (iii) grant liens or grant security interests on its asset in favor of
              the Holders of Senior Notes or guarantee the payment of the Senior
              Notes; or

        (iv)  transfer any of its properties or assets to the Company or any of
              its Subsidiaries,

except for such encumbrances or restrictions existing under or by reason of:

 (a)     Existing Indebtedness as in effect on the date of this Indenture;

 (b)     any Credit Agreement creating or evidencing Indebtedness permitted by
         clause (i) of Section 4.09 and any amendments, modifications,
         restatements, renewals, increases, supplements, refundings,
         replacements or refinancings thereof;

(c)      the Indenture and the Senior Notes;

(d)      applicable law;

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

(f)      purchase money obligations or Vendor Debt for property acquired in the
         ordinary course of business that impose restrictions of the nature
         described in clause (iv) above on the property so acquired;

(g)      Indebtedness incurred pursuant to the clause (viii) of Section 4.09;
         provided that such encumbrance or restriction only relates to the
         Subsidiary or Permitted Joint Venture incurring such Indebtedness; and
<PAGE>
 
(h)      Refinancing Indebtedness, provided that such encumbrances or
         restrictions are no more restrictive than those contained in the
         documentation governing the Indebtedness being extended, refinanced,
         renewed, replaced, defeased or refunded.


Section 4.09.  Incurrence of Indebtedness and Issuance of Preferred Stock.

    The Company shall not, and shall not permit any of its Subsidiaries or Joint
Ventures to, directly or indirectly, create, incur, issue, assume, guaranty or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "incur") any Indebtedness (including, without
limitation, Acquired Indebtedness) and that the Company will not issue any
Disqualified Stock and will not permit any of its Subsidiaries or Joint Ventures
to issue any shares of Preferred Stock; provided that the Company may incur
Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified
Stock if the Company's Consolidated Leverage Ratio as of the last day of the
Company's most recently ended fiscal quarter for which internal financial
statements are available immediately preceding the date on which such
Indebtedness is incurred, or such Disqualified Stock is issued, as the case may
be, would have been (a) greater than zero and less than 5.5 to 1.0, if such
incurrence or issuance is on or prior to March 31, 1999, and (b) greater than
zero and less than 5.0 to 1.0, if such incurrence or issuance is after March 31,
1999, determined on a pro forma basis (including pro forma application of the
net proceeds therefrom) as if such Indebtedness had been incurred, or such
Disqualified Stock had been issued, as the case may be, at the beginning of such
fiscal quarter.

 The foregoing provisions shall not apply to:

       (i)     the incurrence of Indebtedness by the Company, any Subsidiary
               (other than a General Partner Subsidiary) or any Permitted Joint
               Venture pursuant to Credit Agreement(s), provided that the
               aggregate principal amount of such Credit Agreement(s) at any one
               time outstanding under this clause (i) does not exceed $50.0
               million for the Company, all of its Subsidiaries (other than a
               General Partner Subsidiary) and all of its Permitted Joint
               Ventures combined;

       (ii)    the incurrence of Vendor Debt by the Company, any Subsidiary
               (other than a General Partner Subsidiary) or any Permitted Joint
               Venture, provided that the aggregate principal amount of such
               Vendor Debt does not exceed 80% of the purchase price or cost of
               the construction, acquisition or improvement of the applicable
               Telecommunications Related Assets;

       (iii)   Refinancing Indebtedness;

       (iv)    the incurrence of Indebtedness by the Company not to exceed, at
               any one time outstanding, 2.0 times the net cash proceeds
               received by the Company from the issuance and sale of its Capital
               Stock (other than Disqualified Stock) to a Person other than a
               Subsidiary or a Joint
<PAGE>
 
               Venture of the Company, provided that such Indebtedness (y) does
               not mature prior to the Stated Maturity of the Senior Notes and
               has a Weighted Average Life to Maturity longer than the Senior
               Notes and (z) is subordinated to the Senior Notes;

       (v)     the incurrence by the Company of Indebtedness (in addition to
               Indebtedness permitted by any other clause of this paragraph) in
               an aggregate principal amount (or accreted value, as applicable)
               at any time outstanding not to exceed $10.0 million;

       (vi)    the incurrence by any Restricted Joint Venture of Non-Recourse
               Debt, provided that if any Non-Recourse Debt of a Restricted
               Joint Venture ceases to be Non-Recourse Debt, such event shall be
               deemed to constitute an incurrence of Indebtedness as of the date
               such Indebtedness ceases to be Non-Recourse Debt;

       (vii)   the guarantee of Indebtedness by a General Partner Subsidiary in
               connection with the incurrence of Indebtedness by the Restricted
               Joint Venture of which such General Partner Subsidiary is a
               general partner;

       (viii)  the incurrence by the Company's Subsidiaries (other than General
               Partner Subsidiaries) and Permitted Joint Ventures of
               Indebtedness (including Acquired Indebtedness) so long as all of
               the net proceeds of such incurrence are used by such Subsidiary
               or Permitted Joint Venture, as the case may be, directly in
               connection with the design, construction, development or
               acquisition of a Telecommunications Service Market; provided
               that, as of the last day of the Company's most recently ended
               fiscal quarter for which internal financial statements are
               available immediately preceding the date on which such
               Indebtedness is incurred, either: (a) the aggregate principal
               amount of all Indebtedness of such Subsidiary or such Permitted
               Joint Venture does not exceed 1.75 times the Invested Equity
               Capital of such Subsidiary or such Permitted Joint Venture; or
               (b) the Consolidated Leverage Ratio of such Subsidiary or such
               Permitted Joint Venture would not have been greater than 3.5 to
               1.0, in each case determined on a pro forma basis (including pro
               forma application of the net proceeds therefrom) as if such
               Indebtedness had been incurred at the beginning of such fiscal
               quarter; provided, further that any Indebtedness incurred by any
               Subsidiary of the Company or any Permitted Joint Venture (other
               than Related Networks) pursuant to this clause (viii) shall be
               non-recourse with respect to the Company or any other Subsidiary
               of the Company or any other Joint Venture; and

       (ix)    the incurrence by the Company of the Existing Indebtedness.

    For purposes of this Section 4.09, in the event that the Company proposes to
incur Indebtedness pursuant to clause (iv) above, the Company shall,
simultaneously with the incurrence of such Indebtedness, deliver to the Trustee
a resolution of the Board of Directors set forth in an Officers' Certificate
stating that the sale or sales
<PAGE>
 
of Capital Stock forming the basis for the incurrence of such Indebtedness (i)
constitutes a long term investment in the Company and (ii) has not been made for
the purpose of circumventing this Section 4.09. In the event that the Company
rescinds, reverses or unwinds such sale of Capital Stock or otherwise returns or
refunds all or any portion of the net cash proceeds of such sale of Capital
Stock (whether by dividend, distribution or otherwise) within 270 days of the
date of the incurrence of such Indebtedness, such Indebtedness will be deemed to
be incurred on the date of, and immediately after giving effect to, such
rescission, reversal, unwinding, return or refund.

    For purposes of this Section 4.09, in the event that a Restricted Joint
Venture becomes a Permitted Joint Venture or otherwise ceases to be a Restricted
Joint Venture, all of the then outstanding Indebtedness of such entity shall be
deemed to have been incurred as of the date that such Restricted Joint Venture
becomes a Permitted Joint Venture or otherwise ceases to be a Restricted Joint
Venture.


Section 4.10.  Asset Sales.

    The Company shall not, and shall not permit any Subsidiary to, directly or
indirectly, whether in a single transaction or a series of related transactions
occurring within any twelve-month period, make any Asset Sale, unless:

       (i)     the Company or the Subsidiary, as the case may be, receives
               consideration at the time of such Asset Sale at least equal to
               the fair market value (as determined in good faith by the Board
               of Directors) for the shares or assets sold or otherwise disposed
               of; and

       (ii)    at least 90% of such consideration consists of cash, provided
               that

    (A)     an amount equal to the fair market value (as determined in good
            faith by the Board of Directors) of:

            (1)  Telecommunications Related Assets received by the Company or
                 any Subsidiary from the transferee that will be used by the
                 Company or such Subsidiary in the operation of a
                 Telecommunications Business;

            (2)  the Voting Stock of any Person engaged in a Telecommunications
                 Business received by the Company or any Subsidiary; provided
                 that on the date such Voting Stock is received, such Investment
                 in Voting Stock constitutes a Permitted Joint Venture
                 Investment; or

            (3)  the publicly tradeable Voting Stock of any person engaged in
                 the Telecommunications Business received by the Company or any
                 Subsidiary as consideration for a sale of an Equity Interest in
                 any Restricted Joint Venture,
<PAGE>
 
      shall, for the purposes of this Section 4.10, be deemed to be cash which
      was applied in accordance with the first sentence of the penultimate
      paragraph of this Section 4.10; and

    (B)     in the event that any of Hyperion Telecommunications of
            Pennsylvania, Inc., Hyperion Telecommunications of Tennessee, Inc.
            or Hyperion Telecommunications of New York, Inc. sell their
            respective partnership interests in the partnerships to which each
            is a partner to the respective partnerships in the manner specified
            by the applicable partnership agreement, (1) the principal amount of
            any seller note issued to the Company or any of its Wholly Owned
            Subsidiaries shall be deemed to be cash for purposes of this Section
            4.10 and (2) the payments of principal pursuant to such seller note
            shall be deemed to be Net Cash Proceeds (for purposes of the
            penultimate paragraph of this Section 4.10) as and when such
            payments are received.

    For purposes of this Section 4.10, the first $1.0 million of Net Cash
Proceeds received from Asset Sales in any fiscal year shall not be subject to
the restrictions contained in this section.

    In determining the fair market value with respect to any Asset Sale or
series of related Asset Sales involving aggregate consideration in excess of
$10.0 million, the Board of Directors of the Company must obtain an opinion as
to the fairness to the Holders of Senior Notes of such Asset Sales from a
financial point of view issued by a nationally recognized investment banking
firm with total assets in excess of $1.0 billion; provided that no such opinion
shall be required if such Asset Sale is in accordance with the terms of any
Local Partnership Agreement to which the Company or any of its Subsidiaries is a
party on the date hereof.

    The Company may apply the Net Cash Proceeds from any Asset Sale to an
investment in Telecommunications Related Assets in a Telecommunications Service
Market within 180 days after such Asset Sale; provided that if the Company
determines to make such investment in a New Telecommunications Service Market,
the Company shall be deemed to have complied with the first clause of this
sentence if, the Company (y) within 180 days of such Asset Sale, delivers to the
Trustee a resolution adopted by a majority of the Board of Directors set forth
in an Officer's Certificate certifying that the Company intends to utilize the
Net Cash Proceeds of such Asset Sale to invest in a specific new
Telecommunications Service Market and (z) completes such investment within 360
days of such Asset Sale.  The Company shall be deemed to have completed its
investment for purposes of the preceding clause (z), so long as the Company has
(i) a business plan that sets forth the Company's investment plans for the
applicable Telecommunications Service Market and (ii) issued all material
purchase orders to the appropriate parties that are necessary to complete such
business plan.  Any Net Cash Proceeds from an Asset Sale that are not invested
as provided in the two preceding sentences shall constitute Excess Proceeds.
When the aggregate amount of Excess Proceeds exceeds $2.5 million, the Company
shall commence an Asset Sale Offer to purchase the maximum principal amount of
Senior Notes that may be purchased out of the Excess Proceeds, at an offer price
in cash equal to 100% of aggregate principal amount thereof, plus accrued and
unpaid interest to the date of repurchase (or, in the case of repurchases of
Senior Notes prior to April 15, 2001, at a purchase price equal to 100% of the
Accreted Value thereof as of the date of repurchase) in accordance with the
procedures set forth in this Indenture.  To the extent that the aggregate
principal amount thereof, plus accrued and unpaid interest to the date of
repurchase (or, in the
<PAGE>
 
case of repurchases of Senior Notes prior to April 15, 2001, the Accreted Value
thereof as of the date of repurchase) of the Senior Notes tendered pursuant to
an Asset Sale Offer is less than the Excess Proceeds, the Company may use such
remaining Excess Proceeds for any purpose not prohibited by this Indenture. If
the aggregate principal amount thereof, plus accrued and unpaid interest to the
date of repurchase (or, in the case of repurchases of Senior Notes prior to
April 15, 2001, the Accreted Value thereof as of the date of repurchase) of
Senior Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the Trustee shall select the Senior Notes to be purchased on a pro
rata basis. Upon completion of such offer, the amount of Excess Proceeds shall
be reset at zero. Pending application of the Net Cash Proceeds as set forth
above from Asset Sales, all such Net Cash Proceeds shall be placed in escrow for
the benefit of the Holders of Senior Notes.

    Notwithstanding the foregoing, the Company shall not, and shall not permit
any Subsidiary to, directly or indirectly, make any Asset Sale of any Equity
Interests of any Subsidiary (at least 80% of the voting power of the Capital
Stock of which is owned by the Company) except pursuant to an Asset Sale of all
of the Equity Interests of such Subsidiary; provided that any sale of any Equity
Interest of any such Subsidiary to a Strategic Investor shall be deemed not to
be an Asset Sale for purposes of this Section 4.10, so long as such sale of such
Equity Interests does not result in such Subsidiary ceasing to be a Subsidiary
of the Company.


Section 4.11.  Transactions with Affiliates.

    The Company shall not, and shall not permit any of its Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any 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

Note equal in principal amount to any unpurchased portion of the Senior Notes
surrendered by such Holder, if any; provided, that each such new Senior Note

    Neither the Company nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any Senior Notes for or as
inducement to any consent, waiver or amendment of any terms or provisions or the
Senior Notes unless such consideration is offered to be paid or agreed to be
paid to all Holders of Senior Notes which so consent,
<PAGE>
 
waive or agree to amend in the time frame set forth in solicitation documents

Directors on the Company's Board of Directors.  If the Company fails to comply
with this Section 4.20, the Company shall pay Liquidated Damages to each Holder
of the Senior Notes (i) with respect to the first 90-day period immediately
following the occurrence of such default at a rate of 0.5% per annum, determined
daily, on the Accreted Value of the Senior Notes (or after April 15, 2001, on

subsequent 90-day period at a rate increased by an additional 0.25% per annum up
to a maximum aggregate increase of 2.0% per annum until such default has been
cured.

                             DEFAULTS AND REMEDIES


Section 6.01.  Events of Default.

    An "Event of Default" occurs if:

           (a) the Company defaults in the payment when due of interest on, or
         Liquidated Damages with respect to, the Senior Notes and such default
         continues for a period of 30 days;

           (b) the Company defaults in the payment when due of principal of or
         premium, if any, on the Senior Notes when the same becomes due and
         payable at maturity, upon redemption (including in connection with an
         offer to purchase) or otherwise;

           (c) the Company fails to comply with any of the provisions of Section
         4.07, 4.10, 4.15 or 5.01 hereof;

           (d) the Company fails to comply with the provisions described under
         Section 4.09; provided that, for purposes of the last paragraph of
         Section 4.09, in the event that the Company fails to comply with such
         section because Indebtedness is deemed to be incurred by a Restricted
         Joint Venture solely as a result of such Restricted Joint Venture
         ceasing to be a Restricted Joint Venture as a result of (i) the loss of
         a Local Partner or (ii) the loss of management control of such
         Restricted Joint Venture, such failure continues for 90 days;

           (e) the Company fails to observe or perform any other covenant,
         representation, warranty or other agreement in this Indenture or the
         Senior Notes

         for 30 days after notice to the Company by the Trustee or the Holders
         of at least 25% in principal amount of the Senior Notes then
         outstanding;

           (f)  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 date of the Indenture, which default
         (a) is caused by a failure to pay principal of or premium, if any, or
         interest on such Indebtedness prior to the expiration of the grace
         period provided in such Indebtedness on the date of such default (a
         "Payment Default") or (b) results in the acceleration of such
         Indebtedness prior to its express maturity and, in each case, the
         principal amount of any such Indebtedness, together with the principal
         amount of any other such Indebtedness under which there has been a
         Payment Default or the maturity of which has been so accelerated,
         aggregates $5.0 million or more;

           (g) a final judgment or final judgments for the payment of money are
         entered by a court or courts of competent jurisdiction against the
         Company or any of its Subsidiaries or any group of Subsidiaries that,
         taken as a whole, would constitute a Subsidiary and such judgment or
         judgments are not paid within, discharged by or stayed for a period of
         60 days, provided that the aggregate of all such undischarged judgments
         exceeds $5.0 million;

           (h) the Company or any of its Significant Subsidiaries or any of its
         Joint Ventures that would, if it were a Subsidiary constitute a
         Significant Subsidiary, or any group of Subsidiaries or Joint Ventures
         that, taken as a whole, would constitute a Significant Subsidiary
         pursuant to or within the meaning of Bankruptcy Law:

             (i)  commences a voluntary case,

             (ii) consents to the entry of an order for relief against it in an
            involuntary case,

             (iii) consents to the appointment of a Custodian of it or for
            all or substantially all of its property,

             (iv) makes a general assignment for the benefit of its creditors,

             (v)  generally is not paying its debts as they become due; or

          (i) a court of competent jurisdiction enters an order or decree under
         any Bankruptcy Law that:

              (i) is for relief against the Company or any of its Significant
            Subsidiaries or any of its Joint Ventures that would, if it were a
            Subsidiary constitute a Significant Subsidiary, or any group of
            Subsidiaries or Joint
<PAGE>
 
            Ventures that, taken as a whole, would constitute a Significant
            Subsidiary in an involuntary case;

              (ii) appoints a Custodian of the Company or any of its Significant
            Subsidiaries or any of its Joint Ventures that would, if it were a
            Subsidiary constitute a Significant Subsidiary, or any group of
            Subsidiaries or Joint Ventures that, taken as a whole, would
            constitute a Significant Subsidiary or for all or substantially all
            of the property of the Company or any of its Significant
            Subsidiaries or any of its Joint Ventures that would, if it were a
            Subsidiary constitute a Significant Subsidiary, or any group of
            Subsidiaries or Joint Ventures that, taken as a whole, would
            constitute a Significant Subsidiary; or

              (iii) orders the liquidation of the Company or any of its
            Significant Subsidiaries or any of its Joint Ventures that would, if
            it were a Subsidiary constitute a Significant Subsidiary, or any
            group of Subsidiaries or Joint Ventures that, taken as a whole,
            would constitute a Significant Subsidiary;

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

Section 6.02.  Acceleration.

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

    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 Senior Notes pursuant to
Section 3.07 hereof, an equivalent premium shall also become and be immediately
due and payable to the
<PAGE>
 
extent permitted by law upon the acceleration of the Senior Notes. If an Event
of Default occurs prior to April 15, 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 of redemption of the Senior Notes prior to April 15,
2001, then the premium payable for purposes of this paragraph for the period
beginning of the date hereof and ending on April 14, 2001 shall be 106.5% of the
amount that would otherwise be due but for the provisions of this paragraph,
plus accrued interest, if any, to the date of payment. the

    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.

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 Senior Notes or to enforce the performance of any provision of
the Senior Notes or this Indenture.

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

Section 6.04.  Waiver of Past Defaults.

    Holders of not less than a majority in aggregate principal amount of the
then outstanding Senior Notes by notice to the Trustee may on behalf of the
Holders of all of the Senior Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default
in the payment of the principal of, premium and Liquidated Damages, if any, or
interest on, the Senior Notes (including in connection with an offer to
purchase) (provided, however, that the Holders of a majority in aggregate
principal amount of the then outstanding Senior Notes may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration in accordance with Section 6.02 hereof).  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 Senior
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it.
<PAGE>
 
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture that the Trustee determines may be unduly prejudicial to the
rights of other Holders of Senior Notes or that may involve the Trustee in
personal liability.

Section 6.06.  Limitation on Suits.

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

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

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

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

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

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

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

Section 6.07.  Rights of Holders of Senior Notes to Receive Payment.

    Notwithstanding any other provision of this Indenture, the right of any
Holder of a Senior Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Senior Note, on or after the respective due
dates expressed in the Senior Note (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

Section 6.08.  Collection Suit by Trustee.

    If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Senior Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.
<PAGE>
 
Section 6.09.  Trustee May File Proofs of Claim.

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

    In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant.  This Section does

to Section 6.07 hereof, or a suit by Holders of more than 10% in principal
amount of the then outstanding Senior Notes.

                                    TRUSTEE

Section 7.01.  Duties of Trustee.

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

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

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

        (ii) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee shall examine the certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture.

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

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

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

       (iii)  the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05 hereof.

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

    (f) The Trustee shall not be liable for interest on any money received by it
except as the Trustee may agree in writing with the Company.  Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

Section 7.02.  Rights of Trustee.

need not investigate any fact or matter stated in the document.

    (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both.  The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel.  The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

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

    (d) The Trustee shall not be liable for any action it takes or omits to take
in good faith that it believes to be authorized or within the rights or powers
conferred upon it by this Indenture.

    (e) Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

    (f) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders unless such Holders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that might be
incurred by it in compliance with such request or direction.
<PAGE>
 
Section 7.03.  Individual Rights of Trustee.

    The Trustee in its individual or any other capacity may become the owner or
pledgee of Senior Notes and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee.
However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign.  Any Agent may do the same with like rights and
duties.  The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04.  Trustee's Disclaimer.

    The Trustee shall not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Senior Notes, it shall not be
accountable for the Company's use of the proceeds from the Senior Notes or any
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 Senior
Notes or any other document in connection with the sale of the Senior Notes or
pursuant to this Indenture other than its certificate of authentication.

Section 7.05.  Notice of Defaults.

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

Section 7.06.  Reports by Trustee to Holders of the Senior Notes.

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

    A copy of each report at the time of its mailing to the Holders of Senior
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Senior Notes are listed in accordance with TIA (S) 313(d).
The Company shall promptly notify the Trustee when the Senior Notes are listed
on any stock exchange.
<PAGE>
 
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.  To
the extent permitted by law, 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 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, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith.  The Trustee shall notify the 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 may have separate counsel 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 not be unreasonably withheld.

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

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

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

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

Section 7.08.  Replacement of Trustee.

    A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.
<PAGE>
 
    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 Senior Notes
of a majority in principal amount of the then outstanding Senior Notes may
remove the Trustee by so notifying the Trustee and the Company in writing.  The
Company may remove the Trustee if:

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

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

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

       (d) the Trustee becomes incapable of acting.

    If the Trustee resigns or is removed or if a vacancy exists in the office of
Trustee for any reason, the Company shall promptly appoint a successor Trustee.
Within one year after the successor Trustee takes office, the Holders of a
majority in principal amount of the then outstanding Senior Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

    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 Senior Notes of at least 10% in principal amount of the then
outstanding Senior Notes may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

    If the Trustee, after written request by any Holder of a Senior Note who has
been a Holder of a Senior Note for at least six months, fails to comply with
Section 7.10, such Holder of a Senior Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

    A successor Trustee shall deliver a written acceptance of its appointment to
the retiring Trustee and to the Company.  Thereupon, the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and the duties of the Trustee under this Indenture.
The successor Trustee shall mail a notice of its succession to the Holders of
the Senior Notes.  The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided that 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.
<PAGE>
 
Section 7.10.  Eligibility; Disqualification.

    There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities.  The Trustee and its direct parent shall at all times have a
combined capital surplus of at least fifty million dollars.  If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for
purposes of this Section 7.10 the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

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

Section 7.11.  Preferential Collection of Claims Against The Company.

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

                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.  Option to Effect Legal Defeasance or Covenant Defeasance.

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

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, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Senior Notes on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance").  For this purpose, Legal Defeasance means that the Company shall
be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Senior Notes, 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 its other
obligations under such Senior Notes 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 provisions which shall survive
until otherwise terminated or discharged hereunder:  (a) the rights of Holders
of outstanding Senior Notes to receive solely from the trust fund described in
Section 8.04 hereof, and
<PAGE>
 
as more fully set forth in such Section, payments in respect of the principal
of, premium, if any, and interest on such Senior Notes when such payments are
due, (b) the Company's obligations with respect to such Senior Notes under
Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and the Company's obligations in connection
therewith and (d) this Article Eight. Subject to compliance with this Article
Eight, the Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03.  Covenant Defeasance.

    Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof with respect to the outstanding
Senior Notes on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Senior Notes 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 Senior Notes
shall not be deemed outstanding for accounting purposes).  For this purpose,
Covenant Defeasance means that, with respect to the outstanding Senior Notes,
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 Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Senior Notes
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 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(d) through 6.01(g) hereof shall not constitute Events of Default.

Section 8.04.  Conditions to Legal or Covenant Defeasance.

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

    In order to exercise either Legal Defeasance or Covenant Defeasance:

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

have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of the Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of counsel shall confirm that, the Holders of the
outstanding Senior Notes will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same time
as would have been the case if such Legal Defeasance had not occurred;

    (c) in the case of an election under Section 8.03 hereof, the Company shall
have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Senior Notes will not recognize income, gain or loss for federal

the date of such deposit (other than a Default or Event of Default resulting
from the incurrence of Indebtedness all or a portion of the proceeds of which
will be used to defease the Senior Notes pursuant to this Article Eight
concurrently with such incurrence) or insofar as Sections 6.01(h) and 6.01(i)
hereof 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 will 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 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 Senior Notes over the other creditors of the Company
with the intent of defeating, hindering, delaying or defrauding any other
creditors of the Company; 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.
<PAGE>
 
    Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Senior
Notes shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Senior Notes 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 Senior Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

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

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

Section 8.06.  Repayment to The 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 Senior Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest or Liquidated Damages, if any, has
become due and payable shall be paid to the Company on its request or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Senior Note shall thereafter, as a secured 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 non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental
<PAGE>
 
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Senior Notes 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 or Liquidated Damages, if any, on any
Senior Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Senior Notes to receive such
payment from the money held by the Trustee or Paying Agent.

                       AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of the Senior Notes.

      benefits to the Holders of the Senior Notes or that does not adversely
      affect the legal rights hereunder of any Holder of the Senior Note; or

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

    Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section

Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Senior Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture or the Senior Notes may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes (including consents obtained in connection with a
purchase of or a tender offer or exchange offer for the Senior Notes).

    Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Senior Notes 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 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 Senior Notes
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

    After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of each Senior Note 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 Senior Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Senior Notes.  However, without the
consent of each Holder affected, an amendment, supplement or waiver may not
(with respect to any Senior Notes held by a non-consenting Holder):

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

           (b) reduce the principal of or extend the fixed maturity of any
         Senior Note or alter or waive any of the provisions with respect to the
         redemption of the Senior Notes except as provided above with respect to
         Sections 3.09, 4.10 and 4.15 hereof;
<PAGE>
 
           (c) reduce the rate of or change the time for payment of interest,
         including default interest, on any Senior Note;

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

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

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

           (g) make any change in Section 6.04 or 6.07 hereof or in the
         foregoing amendment and waiver provisions; or

           (h) waive a redemption payment with respect to any Senior Note (other
         than a payment required by Sections 3.09, 4.10 and 4.15 hereof).

Section 9.03.  Compliance with Trust Indenture Act.

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

Section 9.04.  Revocation and Effect of Consents.

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

Section 9.05.  Notation on or Exchange of Senior Notes.

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

    Failure to make the appropriate notation or issue a new Senior Note shall
not affect the validity and effect of such amendment, supplement or waiver.
<PAGE>
 
Section 9.06.  Trustee to Sign Amendments, etc.

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

    Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (other than a certificate provided

314(e) and 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

as such, shall have any liability for any obligations of the Company under the
Senior Notes or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation.  Each Holder of Senior Notes by
accepting a Senior Note waives and releases all such liability.  The waiver and
release are part of the
<PAGE>
 
consideration for issuance of the Senior Notes. Such waiver may not be effective
to waive liabilities under the federal securities laws and it is the view of the

copy shall be an original, but all of them together represent the same
agreement.

          ANY PURCHASER OF THE SENIOR NOTE EVIDENCED HEREBY OF THE RESALE
          RESTRICTIONS SET FORTH IN (1) ABOVE.

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

   1.  Interest.  Hyperion Telecommunications, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Senior Note
in the manner specified below. Interest will not accrue prior to April 15, 2001.
Thereafter, interest will accrue at the rate of 13% per annum from April 15,
2001 until maturity (including any additional interest required to be paid
pursuant to the provisions of the Registration Rights Agreement) and will be
payable semi-annually in cash on April 15 and October 15 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"), commencing April 15, 2001. Interest on the Senior
Notes will accrue from the most recent date to which interest has been paid or,
if no interest has been paid, from the date of issuance; provided that if there
is no existing Default in the payment of interest, and if this Senior Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date or if no interest has been paid, from April 15,
2001. The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

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

   3.  Paying Agent and Registrar.  Initially, Bank of Montreal Trust Company,
the Trustee under the Indenture, shall act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity.
<PAGE>
 
   4.  Indenture.  The Company issued the Senior Notes under an Indenture dated
as of April 15, 1996 ("Indenture") between the Company and the Trustee. The
terms of the Senior Notes include those stated in the Indenture and those made a
part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code (S)(S) 77aaa-77bbbb) (the "TIA"). The Senior Notes are
subject to all such terms, and Holders are referred to the Indenture and the TIA
for a statement of such terms. The Senior Notes are senior unsecured obligations
of the Company limited to $329.0 million in aggregate principal amount at
maturity.

   5.  Optional Redemption.

   (a) Except as set forth in subparagraph (b) of this Paragraph 5, the Company
shall not have the option to redeem the Senior Notes prior to April 15, 2001.
Thereafter, the Company shall have the option to redeem the Senior Notes, 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, of, if such
redemption occurs prior to April 15, 2001, the Accreted Value) set forth below
plus accrued and unpaid interest thereon and Liquidated Damages, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning

   (b)  Notwithstanding the foregoing, the Company, on or prior to April 15,
1999, may redeem up to a maximum of 25% of the aggregate principal amount of the
Senior Notes then outstanding at a redemption price of 113.0% of the Accreted
Value thereof, with the net proceeds from either (i) an Initial Public Offering
of the common stock of the Company or (ii) a sale of the Capital Stock (other
than Disqualified Stock) of the Company to a Strategic Investor in a single
transaction or a series of related transactions for at least $25.0 million;
provided that, in either case, at least 75% in aggregate principal amount of the
Senior Notes remain outstanding immediately after the occurrence of such
redemption; and provided, further, that such redemption shall occur within 90
days of the date of the closing of such Initial Public Offering or such sale to
a Strategic Investor, as the case may be.

   6.  Mandatory Redemption.

   Except as set forth in paragraph 7 below, the Company shall not be required
to make mandatory redemption or sinking fund payments with respect to the Senior
Notes.
<PAGE>
 
   7.  Repurchase at Option of Holder.

   (a)  Upon the occurrence of a Change of Control, the Company shall be
required to make an offer (a "Change of Control Offer") to each Holder of the
Senior Notes to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Senior Notes 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 repurchase (or, in the case of
repurchases of the Senior Notes prior to April 15, 2001, at a purchase price
equal to 101% of the Accreted Value thereof as of the date of repurchase) (in
either case, the "Change of Control Payment"). Within ten days following any
Change of Control, the Company shall mail a notice to each Holder setting forth
the procedures governing the Change of Control Offer as required by the
Indenture.

   (b)  If the Company or any Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $2.5 million, the Company shall offer to purchase from all Holders of
Senior Notes (an "Asset Sale Offer") pursuant to Section 3.09 of the Indenture
the maximum principal amount of Senior Notes that may be purchased out of the
Excess Proceeds at an offer price in cash equal to 100% of aggregate principal
amount thereof, plus accrued and unpaid interest to the date of repurchase (or,
in the case of repurchases of the Senior Notes prior to April 15, 2001, at a
purchase price equal to 100% of the Accreted Value thereof as of the date of
repurchase), in accordance with the procedures set forth in the Indenture. To
the extent that the aggregate amount thereof, plus accrued and unpaid interest
to the date of repurchase (or, in the case of repurchases of the Senior Notes
prior to April 15, 2001, at a purchase price equal to 100% of the Accreted Value
thereof as of the date of repurchase) is less than the Excess Proceeds, the
Company may use such remaining Excess Proceeds for any purpose not prohibited by
the Indenture. If the aggregate amount of Senior Notes surrendered by Holders
thereof plus accrued and unpaid interest to the date of repurchase (or, in the
case of repurchases of Senior Notes prior to April 15, 2001, the Accreted Value
thereof as of the date of repurchase) exceeds the amount of Excess Proceeds, the
Trustee shall select the Senior Notes to be purchased on a pro rata basis.
Holders of the Senior Notes that are the subject of an offer to purchase shall
receive an Asset Sale Offer from the Company prior to any related purchase date
and may elect to have such Senior Notes purchased by completing the form titled
"Option of Holder to Elect Purchase" on the reverse of the Senior Notes.

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

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

   10.  Persons Deemed Owners.  The registered Holder of a Senior Note may be
treated as its owner for all purposes.

   11.  Amendment, Supplement and Waiver.  Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Senior Notes, and any existing default or compliance with any provision of the
Indenture or the Senior Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Senior Notes.
Without the consent of any Holder of a Senior Note, the Indenture or the Senior
Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Senior Notes in addition to or in
place of certificated Senior Notes, to provide for the assumption of the
Company's obligations to Holders of the Senior Notes in case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the Holders of the Senior Notes 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.

   12.  Defaults and Remedies.  Events of Default include: (i) default for 30
days in the payment when due of interest on, or Liquidated Damages with respect
to, the Senior Notes; (ii) default in payment when due of principal of or
premium, if any, on the Senior Notes when the same becomes due and payable at
maturity, upon redemption (including in connection with an offer to purchase) or
otherwise, (iii) failure by the Company to comply with Section 4.07, 4.10, 4.15
or 5.01 of the Indenture; (iv) failure by the Company to comply with Section
4.09 of the Indenture; provided that in the event that the Company fails to
comply with Section 4.09 of the Indenture because indebtedness is deemed to be
incurred by a Restricted Joint Venture solely as a result of such Restricted
Joint Venture ceasing to be a Restricted Joint Venture as a result of (x) the
loss of a Local Partner or (y) the loss of management control of such Restricted
Joint Venture, and such failure continues for 90 days; (v) failure by the
Company for 30 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Senior Notes then outstanding to comply
with certain other agreements in the Indenture or the Senior Notes; (vi) default
under certain other agreements relating to Indebtedness of the Company which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vii) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; and (viii) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries or
any of its Joint Ventures that would, if it were a Subsidiary, constitute a
Significant Subsidiary.  If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
<PAGE>
 
outstanding Senior Notes may declare all the Senior Notes to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency with respect to the
Company, any of its Significant Subsidiaries or any Joint Venture that would, if
it were a Subsidiary constitute a Significant Subsidiary, or any group of
Subsidiaries or Joint Ventures that, taken together, would, constitute a
Significant Subsidiary, all outstanding Senior Notes shall become due and
payable without further action or notice.  Holders of the Senior Notes may not
enforce the Indenture or the Senior Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Senior Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders of the Senior Notes notice
of any continuing Default or Event of Default (except a Default or Event of
Default relating to the payment of principal or interest) if it determines that
withholding notice is in their interest.  The Holders of a majority in aggregate
principal amount of the Senior Notes then outstanding by notice to the Trustee
may on behalf of the Holders of all of the Senior Notes waive any existing
Default or Event of Default and its consequences under the Indenture, except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Senior Notes.  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, 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 the Trustee.

   14.  No Recourse Against Others.  A director, officer, employee, incorporator
or stockholder, of the Company, as such, shall not have any liability for any
obligations of the Company under the Senior Notes or the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation.  Each Holder by accepting a Senior Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Senior Notes.

   15.  Authentication.  This Senior Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

   17.  Additional Rights of Holders of Transfer Restricted Securities.  In
addition to the rights provided to Holders of the Senior Notes under the
Indenture, Holders of Transferred Restricted Securities shall have all the
rights set forth in the Registration Rights Agreement dated as of April 15,
1996, between the Company and the parties named on the signature pages thereof
(the "Registration Rights Agreement").

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

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

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 90 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 180 days after the
Closing Date, (iii) in connection with the foregoing, (A) file all pre-effective
<PAGE>
 
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 Series B Senior Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and Consummate the Exchange Offer.  The Exchange Offer shall be on the
appropriate form permitting registration of the Series B Senior Notes to be
offered in exchange for the Series A Senior Notes 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 use its best efforts to 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 Senior Notes
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.

      (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 Senior Notes 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 Senior Notes (other than Transfer
Restricted Securities acquired directly from the Company or any Affiliate of 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 Series B Senior Note 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
Senior Notes held by any such Broker-Dealer, except to the extent required by
the Commission as a result of a change in policy after the date of this
Agreement.

      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 of one year from the date on which the Exchange Offer is
Consummated.

      The Company shall promptly provide sufficient copies of the latest version
of such Prospectus to such Restricted Broker-Dealers promptly upon request, and
in no event later than one day after such request, at any time during such one-
year period in order to facilitate such sales.
<PAGE>
 
SECTION 4.     SHELF REGISTRATION

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

        (x) cause to be filed on or prior to 30 days after the date on which the
    Company determines that it is not required to file the Exchange Offer
    Registration Statement pursuant to clause (i) above or 30 days after the
    date on which the Company receives the notice specified in clause (ii) above
    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 shall

        (y) use its best efforts to cause such Shelf Registration Statement to 
    become effective on or prior to 30 days after the date on which the Company
    becomes obligated to file such Shelf Registration Statement.

      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 shall not be 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 clause (y) above.  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 and subject to
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 of at least three years (as extended pursuant to Section 6(c)(i))
following the date on which such Shelf Registration Statement first becomes
effective under the Act; provided that in the event such applicable policies,
rules and regulations of the Commission are amended to provide for a period of
less than three years, then such period shall be deemed to be in effect for
purposes of this Section 4(a).

      (b) Provision by Holders of Certain Information in Connection with the
          ------------------------------------------------------------------
Shelf Registration Statement.  No Holder of Transfer Restricted Securities may
- ----------------------------                                                  
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 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 used its best efforts to provide all such information.
Each Holder as to which any Shelf
<PAGE>
 
Registration Statement is being effected agrees to furnish promptly to the
Company 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) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the date specified for such filing in this
Agreement, (ii) any such Registration Statement has not been declared effective
by the Commission on or prior to the date specified for such effectiveness in
this Agreement (the "Effectiveness Target Date"), (iii) the Exchange Offer has
                     -------------------------                                
not been Consummated within 30 Business Days of the Effectiveness Target Date
with respect to the Exchange Offer Registration Statement is first declared
effective by the Commission or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose without being succeeded
immediately by a post-effective amendment to such Registration Statement that
cures such failure and that is itself declared effective immediately (each such
event referred to in clauses (i) through (iv), a "Registration Default"), then
                                                  --------------------        
the Company hereby agrees to pay liquidated damages, in cash, to each Holder of
Transfer Restricted Securities with respect to the first 90-day period
immediately following the occurrence of such Registration Default, at a rate of
0.5% per annum, determined daily, on the Accreted Value of the Series A Senior
Notes (or after April 15, 2001, on principal amount of the Series A Senior
Notes) as of the immediately preceding Interest Payment Date. Such interest rate
will increase by an additional 0.25% per annum at the beginning of each
subsequent 90-day period up to a maximum aggregate increase of 2.0% per annum
until all Registration Defaults have been cured, at which time the interest rate
borne by the Series A Senior Notes will be reduced to the original interest
rate.  Notwithstanding anything to the contrary set forth herein, (1) upon
filing of the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement), in the case of (i) above, (2) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon
the filing of a post-effective amendment to the Registration Statement or an
additional Registration Statement that causes the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement) to again be
declared effective or made usable in the case of (iv) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.


      All accrued liquidated damages will be paid by the Company on each Damages
Payment Date to the Global Note Holder by wire transfer of immediately available
funds or by federal funds check and to Holders of Certificated Securities by

satisfied in full.

  Commission policy with respect to exchange offers such as the Exchange Offer,
  such that in the reasonable opinion of counsel to the Company there is a
  substantial question as to whether the Exchange Offer is permitted by
  applicable federal law, the Company hereby agrees to seek a no-action letter
  or other favorable decision from the Commission allowing the Company to
  Consummate an Exchange Offer for such Series A Senior Notes. 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

  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 an analysis prepared by counsel to the
  Company setting forth the legal bases, if any, upon which such counsel has
  concluded that such an Exchange Offer should be permitted and (C) diligently

  such submission.

      (ii)  As a condition to its participation in the Exchange Offer pursuant

  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

  course of business and has no arrangement or understanding with any Person to
  participate in the distribution of the Series B Senior Notes received in the
  Exchange Offer

  Commission as set forth in any no-action letter obtained pursuant to clause

under the Act, which form shall be available for the sale of the Transfer

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 Broker-Dealer Transfer
Restricted Securities by Restricted Broker-Dealers), the 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 such Registration Statement or
  the Prospectus contained therein (A) to contain a material misstatement or
  omission or (B) not to be effective and usable for resale of Transfer
  Restricted Securities during the period required by this 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

      (ii)  prepare and file with the Commission such amendments and post-
  effective amendments to the Registration Statement as may be necessary to keep

  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, 430A and 462, as applicable, under

  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
<PAGE>
 
  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 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)   furnish to the Initial Purchaser(s), 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

  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 prior to the filing of any document that is to be
  incorporated by reference into a Registration Statement or Prospectus, provide
  copies of such document to the selling Holders and to the underwriter(s) in

      (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)  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

  amendment thereto, including all documents incorporated by reference therein
  and all exhibits (including exhibits incorporated therein by reference);

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

      (x)  enter into such agreements (including an underwriting agreement) 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 (or in the case of paragraphs (2) and (3), use its best 
      efforts to furnish) to each selling Holder and each underwriter, if any,
      upon the effectiveness of the Shelf Registration Statement and to each
      Restricted Broker-Dealer upon Consummation of the Exchange Offer:

                (1)  a certificate, dated the date of Consummation of the
           Exchange Offer or the date of effectiveness of the Shelf Registration
           Statement, as the case may be, signed on behalf of the Company by (x)
           the President and (y) the Secretary, any Vice President or any
           Assistant Secretary 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 similar matters as
           the Holders, underwriter(s) and/or Restricted Broker Dealers may
           reasonably request;

                (2)  an opinion, dated the date of Consummation of the Exchange
           Offer or the date of effectiveness of the Shelf Registration
           Statement, as the case may be, of counsel for the Company covering
           matters similar to those set forth in paragraphs f and g of Section 8
           of the Purchase Agreement and such other matter as the Holders,
           underwriters and/or Restricted Broker Dealers may reasonably request,
           and in any event including a statement to the effect that such
           counsel has participated in conferences with officers and other
           representatives of the Company, 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
<PAGE>
 
           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 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 of the Exchange Offer, 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. Without limiting the foregoing, such
           counsel may state further that such counsel assumes no responsibility
           for, and has not independently verified, the accuracy, completeness
           or fairness of the financial statements, notes and schedules and
           other financial data included in any 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 the selling Holders, the underwriter(s), if any,
      and Restricted Broker Dealers, if any, 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 (x).

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,
the selling Holders and each Restricted Broker-Dealer promptly and if requested
by such Persons, shall confirm such advice in writing;

      (xi)  prior to any public offering of Transfer Restricted Securities,
cooperate with the selling Holders, the underwriter(s), if any, and it counsel
in connection with the registration and qualification of the Transfer Restricted

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

or to taxation, other than as to matters and transactions relating to the
Registration Statement, in any jurisdiction where it is not now so subject;

     (xii)  issue, upon the request of any Holder of Series A Senior Notes
covered by any Shelf Registration Statement contemplated by this Agreement,

aggregate principal amount of Series A Senior Notes surrendered to the Company
by such Holder in exchange therefor or being sold by such Holder; such Series B

purchaser(s) of such Senior Notes, as the case may be; in return, the Series A
Senior Notes held by such Holder shall be surrendered to the Company for

     (xiii)  in connection with any sale of Transfer Restricted Securities
that will result in such securities no longer being Transfer Restricted

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;

     (xiv)  use their respective best efforts to cause the disposition of 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 (xi) above;

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

under the Act);

     (xix)  cause the Indenture to be qualified under the TIA not later

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, as
originally filed or any amendment thereof, or any related preliminary prospectus
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 that the Company and its Subsidiaries will not be liable in
any such case to the extent, but only to the extent, that any such loss,
liability, claim, damage or expense arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Holder expressly for use
therein.

      (b)  Each Holder, severally and not jointly, agrees to indemnify and hold
harmless the Company and its Subsidiaries and any of their respective directors,
officers, and any person controlling (within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act) the Company, and the its officers,
directors, partners, employees, representatives and agents of each such person,
to the same extent as the foregoing indemnity from the Company and its
Subsidiaries to each of the indemnified Holders, but only with respect to claims
and actions based on information relating to such Holder furnished in writing by
such Holder expressly for use in any Registration Statement.  In case any action
or proceeding shall be brought against the Company or its Subsidiaries or any of
their respective directors or officers or any such controlling person in respect
of which indemnity may be sought against a Holder, such Holder shall have the
rights and duties given the Company and its Subsidiaries and the Company, such
Subsidiaries, such directors or officers or such controlling person shall have
the rights and duties given to each Holder by the preceding paragraph.  In no
event shall any Holder be liable or responsible for any amount in excess of the
dollar amount of the proceeds received by such Holder upon its sale of the
Transfer Restricted Securities 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 is
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 6 except to the extent that it has been prejudiced
in any material respect by such failure or from any liability which it may
otherwise have). In case any such action is brought against any indemnified
party, and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein, and to the extent
<PAGE>
 
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. 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; provided that the
indemnifying party shall be liable for separate counsel for any indemnified
party in a jurisdiction, if counsel to the indemnified parties shall have
reasonably concluded that there may be defenses available to such indemnified
party that are difference from or additional to those available to one or more
of the other indemnified parties and that separate counsel for such indemnified
party is prudent under the circumstances. Anything in this subsection to the
contrary notwithstanding, an indemnifying party shall not be liable for any
settlement of any claim or action effected without its prior written consent;
provided that such consent was not unreasonably withheld.

      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 the 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 Holder 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 one or more of the Holders
may be subject, in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Holder 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 Holder 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 Company and the Holders 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 or its related indemnified
Holders 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 Transfer Restricted Securities pursuant to a Registration Statement
exceeds the sum of (A) the amount paid by such Holder for such Transfer
Restricted Securities 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
<PAGE>
 
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Series A Notes held by each of the Holders hereunder and not joint.

      For purposes of this Section 8, (A) each person, if any, who controls any
Holder within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act and (B) the respective officers, directors, partners, employees,
representatives and agents of any Initial Purchaser or any controlling person
shall have the same rights to contribution as such Initial Purchaser, 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.  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 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 and during any period in which the
Company is not subject to Section 13 or 15(d) of the Securities Exchange Act, 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

      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, and other documents required under the terms
of such underwriting arrangements.


SECTION 11.    SELECTION OF UNDERWRITERS

      For any Underwritten Offering, the investment banker or investment bankers
and manager or managers for any Underwritten Offering that will administer such
offering will be selected by the Holders of a majority in aggregate principal
amount of the Transfer Restricted Securities included in such offering. 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 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 would not be adequate compensation for any loss incurred
by reason of a breach by them of the provisions of this Agreement and hereby
agree to waive the defense in any action for specific performance that a remedy
at law would be adequate.

      (b) No Inconsistent Agreements.  The Company will not, on or after the
          --------------------------                                        
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof.  The Company has not previously
entered into any agreement granting any registration rights with respect to its
securities to any Person.  The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's securities under any agreement in effect on the date
hereof.

      (c) Adjustments Affecting the Senior Notes.  The Company will not take any
          --------------------------------------                                
action, or voluntarily permit any change to occur, with respect to the Senior
Notes that would materially and adversely affect the ability of the Holders to
Consummate any Exchange Offer.

      (d) Amendments and Waivers.  The provisions of this Agreement may not be
          ----------------------                                              
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 12(d)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities.  Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders whose securities are being tendered pursuant to the Exchange Offer and
that does not affect directly or indirectly the rights of other Holders whose
securities are not being tendered pursuant to such Exchange Offer may be given
by the Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities subject to such Exchange Offer.

      (e) Notices.  All notices and other communications provided for or

                               SUBORDINATED NOTE
                               -----------------


$26,135,524.00                                   Coudersport, Pennsylvania
                                                      April 15, 1996


  For value received, the undersigned, Hyperion Telecommunications, Inc. a
Delaware corporation ("Company"), promises to pay to the order of Adelphia
Communications, Inc., a Delaware corporation ("Lender"), in accordance with the
terms hereof, TWENTY-SIX MILLION ONE HUNDRED THIRTY FIVE THOUSAND FIVE HUNDRED
TWENTY FOUR AND NO/100 DOLLARS ($26,135,524.00) on April 16, 2003.  Company
further promises to pay to the order of Lender interest on the unpaid principal
amount hereof from time to time outstanding at the rate of SIXTEEN AND ONE HALF
PERCENT (16.5%) per annum, payable on the last day of each March, June,
September and December after the date hereof.  Interest on this Subordinated
Note may be paid in cash, through the issuance of additional principal amount of
Subordinated Notes identical hereto (valued at 100% of their principal amount),
or in any combination thereof at the option of the Company.

  All payments of principal and interest on this Subordinated Note are hereby
expressly subordinated to the prior payment in full in cash of all sums owing on
or with respect to the Series A and Series B 13% Senior Discount Subordinated
Notes due 2003 (the "Senior Indebtedness") issued pursuant to that certain
Indenture dated April 15, 1996 between Company and Bank of Montreal Trust
Company, as trustee (the "Trustee") in accordance with the following:

       1.   Upon the occurrence of any default in the payment of any obligation
under or with respect to Senior Indebtedness, no payment or distribution of any
assets of the Company of any kind or character may be made on account of the
principal of or premium, if any, or interest on or any other obligation under or
with respect to, this Subordinated Note or on account of the purchase,
redemption, defeasance or other acquisition of or in respect of, this
Subordinated Note unless and until such default shall have been cured or waived
or shall have ceased to exist or such  Senior Indebtedness shall have been
discharged or paid in full, in cash or, as acceptable to each and every holder
of Senior Indebtedness, in any other manner, after which the Company may resume
making any and all required payments in respect of this Subordinated Note,
including any missed payments.

 
<PAGE>
 
       2.  Upon the occurrence and during the continuance of any non-payment
default with respect to any  Senior Indebtedness pursuant to which the maturity
thereof may be accelerated (a "Non-payment Default"), no payment or distribution
of any assets of the Company of any kind or character (excluding distributions
of equity interests or securities subordinated to the same extent as this
Subordinated Note) may be made on account of the principal of or premium, if
any, or interest on, or any other obligation under, this Subordinated Note or on
account of the purchase, redemption, defeasance or other acquisition of, or in
respect of, this Subordinated Note for the period hereafter specified (the
"Payment Blockage Period"). The Payment Blockage Period shall commence upon the
receipt of notice of the Non-payment Default by the Company from the Trustee and
shall end on the earliest of (i) the 179th day after such commencement, (ii) the
date on which such Non-payment Default (and all Non-payment Defaults as to which
notice is also given after such Payment Blockage Period is initiated) is cured,
waived or ceases to exist or on which such Senior Indebtedness is discharged or
paid in full or (iii) the date on which such Payment Blockage Period (and all
Non-payment Defaults as to which notice is given after such Payment Blockage
Period is initiated) shall have been terminated by written notice to the Company
from the Trustee initiating such Payment Blockage Period, after which, in the
case of each of clauses (i), (ii) and (iii) the Company may resume making any
and all required payments in respect of the Subordinated Note, including any
missed payments.  In no event will a Payment Blockage Period extend beyond 179
days from the date of the receipt by the Company of the notice initiating such
Payment Blockage Period (such 179-day period referred to as the "Initial
Period"), unless in the case of each of the foregoing clauses (i), (ii) and
(iii), the maturity of any  Senior Indebtedness shall have been accelerated or
any payment default thereunder shall exist.  Any number of notices of Non-
payment Defaults may be given during the Initial Period; provided that during
any period of 365 consecutive days only one Payment Blockage Period, during
which payment of principal of, or premium, if any, or interest on, the
Subordinated Note may not be made, may commence and the duration of such period
may not exceed 179 days, unless in the case of each of clauses (i), (ii) and
(iii), the maturity of any  Senior Indebtedness shall have been accelerated or
any payment default thereunder shall exist.  No Non-payment Default will respect
to any  Senior Indebtedness that exists or was continuing on the date of the
commencement of any Payment Blockage Period will be, or can be, made the basis
for the commencement of a second Payment Blockage Period, whether or not within
a period of 365 consecutive days.

 

       3.   In the event of any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or its assets, or
any liquidation, dissolution or other winding up of the Company, whether
<PAGE>
 
voluntary or involuntary, and whether or not involving insolvency or bankruptcy,
or any assignment for the benefit of creditors of any other marshaling of assets
or liabilities of the Company, all Senior Indebtedness must be paid in full, in
cash or, as acceptable to each and every holder of Senior Indebtedness, in any
other manner, before any payment or distribution is made on account of the
principal of or premium, if any, or interest on or any other obligation under or
with respect to the Subordinated Note or on account of the purchase, redemption,
defeasance or other acquisition of, or in respect of, this Subordinated Note.


       4.   In the event that the Lender receives any payment of principal of,
interest on, or premium, if any, with respect to the Subordinated Note at a time
when such Lender, has actual knowledge that such payment is prohibited by the
terms of this Note, such payment shall be held by the Lender, in trust for the
benefit of, and shall be paid forthwith over and delivered, upon written
request, to, the holders of Senior Indebtedness for application to the payment
of all obligations with respect to Senior Indebtedness 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 Indebtedness.


  Company hereby expressly waives presentment, demand, notice, protest, and all
other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement of this Note, and an action for amounts due
hereunder shall immediately accrue.
<PAGE>
 
  This Note shall be governed by, construed and enforced in accordance with the
laws of the State of Delaware without regard to principles of choice of law.

                                 June 20, 1996


Hyperion Telecommunications, Inc.
5 West Third Street
Coudersport, PA  16915

Dear Sirs:

     We have acted as counsel to Hyperion Telecommunications, Inc., a Delaware
corporation (the "Company"), in connection with the proposed exchange (the
"Exchange") by the Company of 13% Series B Senior Discount Notes Due 2003 ("New
Notes") for an equal principal amount of its outstanding 13% Senior Discount
Notes Due 2003 ("Old Notes").

     In connection with the proposed Exchange, we have examined the Certificate
of Incorporation of the Company, as amended, the Bylaws of the Company, the
relevant corporate proceedings of the Company, the draft Registration Statement
on Form S-4 covering the proposed Exchange (the "Registration Statement"),
including the Prospectus filed as a part of the Registration Statement, the
Indenture dated April 15, 1996 with respect to the Old Notes and New Notes (the
"Indenture"), and such other documents, records, certificates of public
officials, statutes and decisions as we considered necessary to express the
opinions contained herein.  In the examination of such documents, we have
assumed the genuiness of all signatures and the authenticity of all documents
submitted to us as originals and the conformity to the original documents of all
documents submitted to us as certified or photostatic copies.

     We understand that the New Notes are to be issued to the holders of the Old
Notes in the Exchange and are to be available for resale by such holders, all in
the manner described in the Prospectus which is a part of the Registration
Statement and in the Indenture.

     Based on the foregoing, we are of the opinion that:

     1. The issuance of the New Notes to the holders of the Old Notes pursuant
        to the terms of the Exchange and the Indenture have been duly authorized
        by proper corporate action of the Company.

     2. When the Registration Statement shall have been declared effective by
        order of the Securities and Exchange Commission and the New Notes have
        been duly issued to and exchanged for the Old Notes in accordance with

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

                                     -2-
<PAGE>
 
                    The Lender hereby agrees to make a Loan to the Borrower, 
on the Borrowing Date subject to and on the terms and conditions set forth
herein, the aggregate principal amount of which shall not exceed $1,000,000. 
The Loan is not a revolving credit loan and the Borrower shall not have the
right to borrow, repay and reborrow hereunder.  The obligation of the Borrower
to repay the principal amount of the Loan, together with interest thereon,
shall be evidenced by the Note duly executed and delivered by the Borrower with
the blanks appropriately completed.  The entire unpaid principal balance of the
Loan and interest accrued thereon shall be due and paid in full on the Maturity
Date. The Borrower shall have the right at its option from time to time to
prepay the Loan in whole or in part.  Any interest that accrues on the Loan
from the date six months after the date of the Loan shall be offset by bonus or
additional compensation payable to the Borrower by the Lender (the "Bonus
Payment") which payment shall be payable at the time the principal of and
interest on the Loan are due and payable, whether at the Maturity Date, by
acceleration or otherwise. In addition, the Lender shall make an additional
payment (the "Gross-Up Payment") to the Borrower in an amount equal to the
Federal, state and local income taxes payable by the Borrower with respect to
the Bonus Payment.  In computing the Gross-Up Payment, the Bonus Payment shall
be reduced by the amount, if any, of the interest that accrued on the Loan from
the date six months after the date of the Loan that is deductible for Federal,
state or local tax purposes.  After the Gross-Up Payment is so determined, the
Borrower shall also be entitled to receive additional payments in an amount
such that after payment by the Borrower of all Federal, state and local income
taxes imposed upon the Gross-Up Payment the Borrower shall retain an amount
equal to the Gross-Up Payment.

               (b)  Interest Rate.
                    --------------

                    The Note shall bear interest on the unpaid principal amount
of the Loan for each day (computed on the basis of the actual number of days
elapsed over a year of 365/366 days) at a rate per annum equal to the average

time. Interest on the Loan shall be due and payable on the Maturity Date or
upon acceleration of the Note.

          3.   Pledge.
               -------

As security for the due and punctual payment and performance of the Debt in
full, the Borrower hereby agrees that the Lender shall have, and the Borrower
hereby grants to and creates in favor of the Lender, a first priority security
interest under the Code in and to all of the Collateral.

          4.   Delivery of Certificates, etc.
               ------------------------------

The Borrower represents and warrants to the Lender as follows:

               (a)  The Borrower has good and marketable title to all of the 
Collateral free and clear of any pledge, lien, security interest, encumbrance,
option or rights of others, except to the extent transfer of the Collateral may
be restricted by the Federal Securities Act of 1933, as amended, and state
securities laws and other than the security interest granted to and created in
favor of the Lender hereunder.

               (b)  The Borrower (i) is an individual resident of Allegheny 
County, Pennsylvania and has the legal capacity, power and authority to borrow
money, to execute and deliver the Note and this Agreement and to assign,
indorse, transfer and deliver, and pledge to Lender the Collateral and
otherwise perform its obligations as provided herein, and (ii) does not require
the approval of or consent to any of such acts by any regulatory agency or
other governmental authority or other third party.

               (c)  The execution, delivery and performance by the Borrower of t
his Agreement, the Note and the other Loan Documents to which each is a party
are within the legal capacity and power of the Borrower, require no action by
or in respect of, or filing with, any governmental body, agency or official and
do not violate, contravene, or constitute a default under, any provision of any
applicable law or regulation, or of any agreement, judgment, injunction, order,
decree or other instrument binding upon the Borrower or his properties (except
to the extent that any required consent has been obtained) and will not result
in the creation or imposition of any lien on any asset of the Borrower except
for liens in favor of the Lender created hereunder.

               (d)  This Agreement, the Note and the other Loan Documents 
constitute valid and binding agreements and instruments of the Borrower,
enforceable against the Borrower in accordance with the terms thereof, except
as enforceability may be limited by bankruptcy, insolvency or similar laws
affecting creditors' rights generally or general principles of equity.

               (e)  The Borrower is not in violation of or breach or default 
under any provision of any law, rule or regulation, or any agreement, lease or
other instrument to which the Borrower is a party or by which he or his
properties are bound, which default would materially adversely affect the
Borrower's ability to repay the principal of and interest on the Loan and
pledge the Collateral hereunder.

               (f)  There is no action, suit or proceeding pending or, to the 
knowledge of the Borrower, threatened against or affecting the Borrower or any
of the Borrower's properties before any court, arbitrator or governmental body,
agency or official which would materially adversely affect the Borrower or the
Collateral.

          6.   Further Assurances.
               -------------------

                                     -4-
<PAGE>
 
The Borrower will faithfully preserve and protect the Lender's security interest
in the Collateral as a first priority perfected security interest under the
Code, and will do all such other acts and things, and will upon request therefor
by the Lender execute and deliver all such other documents and instruments,
including, without limitation, further pledges, assignments, documents and
powers of attorney with respect to the Collateral consistent with the terms of
this Agreement, as the Lender in its sole discretion may deem necessary or
advisable from time to time in order to preserve, perfect and protect said
security interest.

          7.   Certain Covenants of the Borrower.
               ----------------------------------

The Borrower covenants and agrees that (a) he will defend the Lender's right,
title and security interest in and to the Collateral and the proceeds thereof
against the claims and demands of all persons whomsoever; (b) he will have like
title to and right to pledge any other property at any time hereafter pledged to
the Lender pursuant to this Agreement and will likewise defend the Lender's
right thereto and security interest therein; (c) he will not assign, transfer,
pledge, or otherwise encumber any of his right, title or interest under, in or
to the Collateral other than pursuant hereto; (d) he will not take or omit to
take any action, or permit any subsidiary any shares of capital stock of which
constitute a part of the Collateral to take or omit to take any action, the
taking or the omission of which might result in an alteration or impairment of
the Collateral or of this Agreement; (e) he will not, without the prior written
consent of the Lender, waive or release any obligation of any party to the
Collateral; (f) he will execute and deliver to the Lender and record such
supplements to this Agreement and additional assignments as the Lender
reasonably may request to evidence and confirm the pledge herein contained; and
(g) he will promptly give notice in writing to the Lender of the occurrence of
any litigation or proceedings affecting the Borrower or of any dispute between
the Borrower and any governmental or quasi-governmental authority  or any other
person (including, without limitation, any material changes in the federal
income tax filings of the Borrower which may be proposed on audit) if such
litigation, proceeding or dispute is one which would, if adversely determined,
have a material adverse effect on the Borrower or the Collateral.

          8.   Protection of the Lender's Interest in the Collateral Against 
               -------------------------------------------------------------
               Others.
               -------

The Borrower assumes full responsibility for taking any and all necessary steps
to preserve the Lender's rights with respect to the Collateral against all
others.  The Lender shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Lender takes
such action for that purpose as the Borrower shall request in writing, provided
that such requested action will not, in the judgment of the Lender, impair the
security interest in the Collateral created hereby or the Lender's rights in, or
the value of, the Collateral, and provided further that such written request is
received by the Lender in sufficient time to permit the Lender to take the
requested action.

          9.   Continuation of Perfection of Security Interest.
               ------------------------------------------------

The Borrower shall at the Borrower's own cost and expense cause the security
interest in the Collateral granted to and created in favor of the Lender under
this Agreement to be perfected and continue to be perfected as long as the Debt
or any part thereof is outstanding and unpaid or not

                                     -5-
<PAGE>
 
performed in full, and for such purpose the Borrower shall from time to time
deliver possession to the Lender of and execute, deliver and file or record (or
cause to be filed or recorded) such instruments, documents and notices
(including, without limitation, amendments or supplements to this Agreement,
financing statements and continuation statements) as the Lender may deem
necessary or advisable from time to time in order to confirm, perfect and
preserve such security interest. The Lender is hereby irrevocably appointed
attorney-in-fact of the Borrower to do all acts and things which the Lender, in
the exercise of its responsibilities under this Agreement, may deem necessary
or advisable to perfect and continue perfected the Lender's security interest
in the Collateral.

          10.  Voting Rights; Dividends; etc.
               ------------------------------

So long as no Event of Default shall have occurred:

               (a)  The Borrower shall be entitled to exercise any and all 
voting and other consensual rights pertaining to the Collateral or any part
thereof for any purpose not inconsistent with the terms of this Agreement;
provided, however, that the Borrower shall not exercise or refrain from
exercising any such right if such action or inaction would reasonably be likely
to have a material adverse effect on the value of the Collateral or any part
thereof; and provided, further, that the Borrower shall give the Lender at
least five (5) business days' written notice of the manner in which it intends
to exercise, and the reasons therefor, or the reasons for refraining from
exercising, any such right;

               (b)  Any and all instruments and other property (other than 
cash dividends) received, receivable or otherwise distributed in respect of, or
in exchange for, any of the Collateral shall be forthwith delivered to the
Lender to hold as part of the Collateral and shall, if received by the
Borrower, be received in trust for the benefit of the Lender, be segregated
from the other property or funds of the Borrower, and be forthwith delivered to
the Lender as Collateral in the same form as so received (with any necessary
indorsement); and

               (c)  The Lender shall execute and deliver (or cause to be 
executed and delivered) to the Borrower all such proxies and other instruments
as the Borrower may reasonably request for the purpose of enabling the Borrower
to exercise the voting and other rights which he is entitled to exercise
pursuant to paragraph (a) above, and to receive the dividends which he is
authorized to receive and retain pursuant to paragraph (b) above.

          11.  Defaults.
               -----------

               (a)  An Event of Default shall occur if:

                    (i)   The Borrower shall fail to pay on or before the date 
five business days after the date due, whether at maturity, by acceleration or
otherwise, of any principal of or interest on the Note; or

                                     -6-
<PAGE>
 
                    (ii)  The Borrower shall fail to observe or perform any of 
his covenants contained herein, and such failure shall continue for a period of
thirty (30) days after written notice from the Lender to the Borrower; or

                   (iii)  Any representation, warranty, certification or 
statement made by the Borrower in this Agreement, or in any certificate,
financial statement or other document delivered to the Lender pursuant to or in
connection with this Agreement or the making of the Loan shall prove to have
been incorrect in any material respect when made; or

                    (iv)  The Borrower shall commence a voluntary case or 
other proceeding seeking reorganization or other relief with respect to his
debts under any bankruptcy, insolvency or other similar law now or hereafter in
effect or seeking the appointment of a trustee, custodian or other similar
official of himself or any substantial part of his property, or shall consent
to any such relief or to the appointment of or taking possession by any such
official in an involuntary case or other proceeding commenced against him, or
shall make a general assignment for the benefit of creditors, or shall fail
generally to pay his debts as they become due, or shall take any action to
authorize any of the foregoing; or

                    (v)   an involuntary case or other proceeding shall be 
commenced against the Borrower seeking reorganization or other relief with
respect to his debts under any bankruptcy, insolvency or other similar law now
or hereafter in effect or seeking the appointment of a trustee, custodian or
other similar official of himself or any substantial part of his property, and
such involuntary case or other proceeding shall remain undismissed for a period
of 60 days.

               (b)  Upon the occurrence of an Event of Default under the terms
of this Agreement:

                    (i)   All rights of the Borrower to exercise the voting and
other consensual rights which it would otherwise be entitled to exercise
pursuant to Section 10(a) and to receive the dividends which it would otherwise
be authorized to receive and retain pursuant to Section 10(b) shall cease, and
all such rights shall, upon notice by the Lender to the Borrower, become vested
in the Lender, who shall thereupon have the sole right to exercise such voting
and other consensual rights and the sole right to receive and hold as
Collateral such dividends and apply them to payment of the Debt; and

                    (ii)  All dividends which are received by the Borrower 
contrary to the provisions of paragraph (i) of this Section 11(b) shall be
received in trust for the benefit of the Lender, shall be segregated from other
funds of the Borrower and shall be forthwith paid over to the Lender as
Collateral in the same form as so received (with any necessary indorsement).

          12.  Remedies Upon the Occurrence of an Event of Default.
               ----------------------------------------------------

                                     -7-
<PAGE>
 
               (a)  If an Event of Default specified under Section 11(a)(i) 
through Section 11(a)(iii) hereof shall occur and be continuing, the Lender may
by written notice to the Borrower, declare the unpaid principal amount of the
Note then outstanding and all interest accrued thereon, any unpaid fees and all
other obligations of the Borrower to the Lender hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be
immediately due and payable to the Lender without presentment, demand, protest
or any other notice of any kind, all of which are hereby expressly waived; and

               (b)  If an Event of Default specified under Section 11(a)(iv) 
through (v) shall occur, the Lender shall be under no further obligations to
make any Loan hereunder and the unpaid principal amount of the Note then
outstanding and all interest accrued thereon, any unpaid fees and all other
obligations of the Borrower to the Lender hereunder and thereunder shall be
immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived.

               (c)  If there shall have occurred an Event of Default under the 
terms of this Agreement, then the Lender shall have such rights and remedies
with respect to the Collateral or any part thereof and the proceeds thereof as
are provided by the Code and such other rights and remedies with respect
thereto which it may have at law or in equity or under this Agreement,
including without limitation, to the extent not inconsistent with the
provisions of the Code, the right to (i) transfer all or any part of the
Collateral into the Lender's name or into the name of its nominee and
thereafter receive all cash, stock and other dividends or distributions paid or
payable in respect thereof, and otherwise act with respect thereto as the
absolute owner thereof, and (ii) sell, assign, give an option or options to
purchase or otherwise dispose of all or any part of the Collateral at any sale
as provided by the Code at such place or places and at such time or times and
upon such terms, whether for cash or on credit, and in such manner as the
Lender may determine, and apply the proceeds so received (A) first to the
payment of the costs and expenses incurred by the Lender in connection with
such sale and other costs and expenses referred to in clauses (ii) and (iii) of
the definition of "Debt," (B) second to the repayment of all amounts then due
and unpaid on the Debt, whether on account of principal, interest, fees,
expenses or otherwise, and (C) then to pay the balance, if any, as required by
law.  The Borrower shall be liable for any deficiency if the proceeds of any
sale, assignment, giving of an option or options to purchase or other
disposition of the Collateral is insufficient to pay all amounts to which the
Lender is entitled.  Any excess proceeds from the sale, assignment, giving of
an option or options to purchase or other disposition of the Collateral after
payment of all amounts to which the Lender is entitled shall be paid to
Borrower.

         13.   Notice of Sale of the Collateral by the Lender.
               -----------------------------------------------

If any notification of intended sale of any of the Collateral is required by
law, such notification shall be deemed reasonable if mailed at least ten (10)
days before such sale, postage prepaid, addressed to the Borrower as provided in
Section 17 hereof.

          14.  Private Sale of the Collateral.
               -------------------------------

                                     -8-
<PAGE>
 
The Borrower recognizes that the Lender may be compelled to resort to one or
more private sales of the Collateral to a restricted group of purchasers who
will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Borrower acknowledges and agrees that any such private sale
may result in prices and other terms less favorable to the seller than if such
sale were a public sale and, notwithstanding such circumstances, agrees that any
such private sale shall not, for such reason alone, be deemed to have been made
in a commercially unreasonable manner.  The Lender shall not be under any
obligation to delay a sale of any of the Collateral for the period of time
necessary to permit the registration of such securities for public sale under
the Federal Securities Act of 1933, as amended, or under applicable state
securities laws.

          15.  Binding Effect; Termination.
               ----------------------------

Upon payment in full of the Debt, this Agreement shall terminate and be of no
further force and effect, and the Lender shall thereupon promptly return to the
Borrower such of the Collateral and such other documents delivered by the
Borrower hereunder as may then be in the Lender's possession.  Until such time,
however, this Agreement shall be binding upon and inure to the benefit of the
parties hereto, their respective successors and assigns.

          16. Non-Waiver; Cumulative Remedies.
              --------------------------------

No failure or delay on the part of the Lender in exercising any right, remedy,
power or privilege hereunder shall operate as a waiver thereof or of any other
right, remedy, power or privilege of the Lender hereunder; nor shall any single
or partial exercise of any such right, remedy, power or privilege preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.  The rights and remedies of the Lender under this Agreement
are cumulative and not exclusive of any rights or remedies which it may
otherwise have.

          17.  Notices.
               --------

All notices and other communications which are required or may be given under
this Agreement shall be in writing and may be delivered by one of the following
methods of delivery:  (i) personally; (ii) by registered or certified mail,
return receipt requested, postage prepaid; (iii) by overnight courier; or (iv)

change in the manner provided.

          18.  Successors and Assigns.

its successors and assigns, and the Borrower and his successors and assigns,
except that the Borrower may not assign or transfer the Borrower's obligations
hereunder or any interest herein.

          19.  Governing Law.

prohibition or unenforceability in any jurisdiction shall not invalidate or

              ---------

              (a)  Agreement to Make the Loan; Prepayments & Offset.
                   -------------------------------------------------

                                     -2-
<PAGE>
 
          The Lender hereby agrees to make a Loan to the Borrower, on the
Borrowing Date subject to and on the terms and conditions set forth herein, the
aggregate principal amount of which shall not exceed $1,000,000.  The Loan is
not a revolving credit loan and the Borrower shall not have the right to borrow,
repay and reborrow hereunder.  The obligation of the Borrower to repay the
principal amount of the Loan, together with interest thereon, shall be evidenced
by the Note duly executed and delivered by the Borrower with the blanks
appropriately completed.  The entire unpaid principal balance of the Loan and
interest accrued thereon shall be due and paid in full on the Maturity Date.
The Borrower shall have the right at its option from time to time to prepay the
Loan in whole or in part.  Any interest that accrues on the Loan from the date
six months after the date of the Loan shall be offset by bonus or additional
compensation payable to the Borrower by the Lender (the "Bonus Payment") which
payment shall be payable at the time the principal of and interest on the Loan
are due and payable, whether at the Maturity Date, by acceleration or otherwise.
In addition, the Lender shall make an additional payment (the "Gross-Up
Payment") to the Borrower in an amount equal to the Federal, state and local
income taxes payable by the Borrower with respect to the Bonus Payment.  In
computing the Gross-Up Payment, the Bonus Payment shall be reduced by the
amount, if any, of the interest that accrued on the Loan from the date six
months after the date of the Loan that is deductible for Federal, state or local
tax purposes.  After the Gross-Up Payment is so determined, the Borrower shall
also be entitled to receive additional payments in an amount such that after
payment by the Borrower of all Federal, state and local income taxes imposed
upon the Gross-Up Payment the Borrower shall retain an amount equal to the
Gross-Up Payment.

               (b)  Interest Rate.
                    --------------

          The Note shall bear interest on the unpaid principal amount of the
Loan for each day (computed on the basis of the actual number of days elapsed
over a year of 365/366 days) at a rate per annum equal to the average rate at
which Lender is able to invest cash on a short-term basis from time to time.
Interest on the Loan shall be due and payable on the Maturity Date or upon
acceleration of the Note.

          3.   Pledge.
               -------

As security for the due and punctual payment and performance of the Debt in
full, the Borrower hereby agrees that the Lender shall have, and the Borrower
hereby grants to and creates in favor of the Lender, a first priority security
interest under the Code in and to all of the Collateral.

          4.   Delivery of Certificates, etc.
               ------------------------------

Upon the execution and delivery of this Agreement, the Borrower has delivered to
and deposited with the Lender in pledge, stock certificates and any other
instruments evidencing the Collateral, together with undated stock powers signed
in blank by the Borrower as the Lender shall have required.

          5.   Representations and Warranties.

<PAGE>
 
The Borrower represents and warrants to the Lender as follows:

               (a)  The Borrower has good and marketable title to all of the 
Collateral free and clear of any pledge, lien, security interest, encumbrance,
option or rights of others, except to the extent transfer of the Collateral may
be restricted by the Federal Securities Act of 1933, as amended, and state
securities laws and other than the security interest granted to and created in
favor of the Lender hereunder.

               (b)  The Borrower (i) is an individual resident of Allegheny 
County, Pennsylvania and has the legal capacity, power and authority to borrow
money, to execute and deliver the Note and this Agreement and to assign,
indorse, transfer and deliver, and pledge to Lender the Collateral and
otherwise perform its obligations as provided herein, and (ii) does not require
the approval of or consent to any of such acts by any regulatory agency or
other governmental authority or other third party.

               (c)  The execution, delivery and performance by the Borrower of 
this Agreement, the Note and the other Loan Documents to which each is a party
are within the legal capacity and power of the Borrower, require no action by
or in respect of, or filing with, any governmental body, agency or official and
do not violate, contravene, or constitute a default under, any provision of any
applicable law or regulation, or of any agreement, judgment, injunction, order,
decree or other instrument binding upon the Borrower or his properties (except
to the extent that any required consent has been obtained) and will not result
in the creation or imposition of any lien on any asset of the Borrower except
for liens in favor of the Lender created hereunder.

               (d)  This Agreement, the Note and the other Loan Documents 
constitute valid and binding agreements and instruments of the Borrower,
enforceable against the Borrower in accordance with the terms thereof, except
as enforceability may be limited by bankruptcy, insolvency or similar laws
affecting creditors' rights generally or general principles of equity.

               (e)  The Borrower is not in violation of or breach or default 
under any provision of any law, rule or regulation, or any agreement, lease or
other instrument to which the Borrower is a party or by which he or his
properties are bound, which default would materially adversely affect the
Borrower's ability to repay the principal of and interest on the Loan and
pledge the Collateral hereunder.

               (f)  There is no action, suit or proceeding pending or, to the 
knowledge of the Borrower, threatened against or affecting the Borrower or any
of the Borrower's properties before any court, arbitrator or governmental body,
agency or official which would materially adversely affect the Borrower or the
Collateral.

          6.   Further Assurances.
               -------------------

                                     -4-
<PAGE>
 
The Borrower will faithfully preserve and protect the Lender's security interest
in the Collateral as a first priority perfected security interest under the
Code, and will do all such other acts and things, and will upon request therefor
by the Lender execute and deliver all such other documents and instruments,
including, without limitation, further pledges, assignments, documents and
powers of attorney with respect to the Collateral consistent with the terms of
this Agreement, as the Lender in its sole discretion may deem necessary or
advisable from time to time in order to preserve, perfect and protect said
security interest.

          7.   Certain Covenants of the Borrower.
               ----------------------------------

The Borrower covenants and agrees that (a) he will defend the Lender's right,
title and security interest in and to the Collateral and the proceeds thereof
against the claims and demands of all persons whomsoever; (b) he will have like
title to and right to pledge any other property at any time hereafter pledged to
the Lender pursuant to this Agreement and will likewise defend the Lender's
right thereto and security interest therein; (c) he will not assign, transfer,
pledge, or otherwise encumber any of his right, title or interest under, in or
to the Collateral other than pursuant hereto; (d) he will not take or omit to
take any action, or permit any subsidiary any shares of capital stock of which
constitute a part of the Collateral to take or omit to take any action, the
taking or the omission of which might result in an alteration or impairment of
the Collateral or of this Agreement; (e) he will not, without the prior written
consent of the Lender, waive or release any obligation of any party to the
Collateral; (f) he will execute and deliver to the Lender and record such
supplements to this Agreement and additional assignments as the Lender
reasonably may request to evidence and confirm the pledge herein contained; and
(g) he will promptly give notice in writing to the Lender of the occurrence of
any litigation or proceedings affecting the Borrower or of any dispute between
the Borrower and any governmental or quasi-governmental authority  or any other
person (including, without limitation, any material changes in the federal
income tax filings of the Borrower which may be proposed on audit) if such
litigation, proceeding or dispute is one which would, if adversely determined,
have a material adverse effect on the Borrower or the Collateral.

          8.   Protection of the Lender's Interest in the Collateral Against 
               -------------------------------------------------------------
               Others.
               -------

The Borrower assumes full responsibility for taking any and all necessary steps
to preserve the Lender's rights with respect to the Collateral against all
others.  The Lender shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Lender takes
such action for that purpose as the Borrower shall request in writing, provided
that such requested action will not, in the judgment of the Lender, impair the
security interest in the Collateral created hereby or the Lender's rights in, or
the value of, the Collateral, and provided further that such written request is
received by the Lender in sufficient time to permit the Lender to take the
requested action.

          9.   Continuation of Perfection of Security Interest.
               ------------------------------------------------

The Borrower shall at the Borrower's own cost and expense cause the security
interest in the Collateral granted to and created in favor of the Lender under
this Agreement to be perfected and continue to be perfected as long as the Debt
or any part thereof is outstanding and unpaid or not

                                     -5-
<PAGE>
 
performed in full, and for such purpose the Borrower shall from time to time
deliver possession to the Lender of and execute, deliver and file or record (or
cause to be filed or recorded) such instruments, documents and notices
(including, without limitation, amendments or supplements to this Agreement,
financing statements and continuation statements) as the Lender may deem
necessary or advisable from time to time in order to confirm, perfect and
preserve such security interest. The Lender is hereby irrevocably appointed
attorney-in-fact of the Borrower to do all acts and things which the Lender, in
the exercise of its responsibilities under this Agreement, may deem necessary
or advisable to perfect and continue perfected the Lender's security interest
in the Collateral.

          10.  Voting Rights; Dividends; etc.
               ------------------------------

So long as no Event of Default shall have occurred:

               (a)  The Borrower shall be entitled to exercise any and all 
voting and other consensual rights pertaining to the Collateral or any part
thereof for any purpose not inconsistent with the terms of this Agreement;
provided, however, that the Borrower shall not exercise or refrain from
- --------  -------
exercising any such right if such action or inaction would reasonably be likely
to have a material adverse effect on the value of the Collateral or any part
thereof; and provided, further, that the Borrower shall give the Lender at
             --------  -------
least five (5) business days' written notice of the manner in which it intends
to exercise, and the reasons therefor, or the reasons for refraining from
exercising, any such right;

               (b)  Any and all instruments and other property (other than 
cash dividends) received, receivable or otherwise distributed in respect of, or
in exchange for, any of the Collateral shall be forthwith delivered to the
Lender to hold as part of the Collateral and shall, if received by the
Borrower, be received in trust for the benefit of the Lender, be segregated
from the other property or funds of the Borrower, and be forthwith delivered to
the Lender as Collateral in the same form as so received (with any necessary
indorsement); and

               (c)  The Lender shall execute and deliver (or cause to be 
executed and delivered) to the Borrower all such proxies and other instruments
as the Borrower may reasonably request for the purpose of enabling the Borrower
to exercise the voting and other rights which he is entitled to exercise
pursuant to paragraph (a) above, and to receive the dividends which he is
authorized to receive and retain pursuant to paragraph (b) above.

          11.  Defaults.
               ---------

               (a)  An Event of Default shall occur if:

                    (i)   The Borrower shall fail to pay on or before the date 
five business days after the date due, whether at maturity, by acceleration or
otherwise, of any principal of or interest on the Note; or

                                     -6-
<PAGE>
 
                    (ii)  The Borrower shall fail to observe or perform any of 
his covenants contained herein, and such failure shall continue for a period of
thirty (30) days after written notice from the Lender to the Borrower; or

                    (iii) Any representation, warranty, certification or 
statement made by the Borrower in this Agreement, or in any certificate,
financial statement or other document delivered to the Lender pursuant to or in
connection with this Agreement or the making of the Loan shall prove to have
been incorrect in any material respect when made; or

                    (iv)  The Borrower shall commence a voluntary case or other
proceeding seeking reorganization or other relief with respect to his debts
under any bankruptcy, insolvency or other similar law now or hereafter in
effect or seeking the appointment of a trustee, custodian or other similar
official of himself or any substantial part of his property, or shall consent
to any such relief or to the appointment of or taking possession by any such
official in an involuntary case or other proceeding commenced against him, or
shall make a general assignment for the benefit of creditors, or shall fail
generally to pay his debts as they become due, or shall take any action to
authorize any of the foregoing; or

                    (v)   an involuntary case or other proceeding shall be 
commenced against the Borrower seeking reorganization or other relief with
respect to his debts under any bankruptcy, insolvency or other similar law now
or hereafter in effect or seeking the appointment of a trustee, custodian or
other similar official of himself or any substantial part of his property, and
such involuntary case or other proceeding shall remain undismissed for a period
of 60 days.

               (b)  Upon the occurrence of an Event of Default under the terms 
of this Agreement:

                    (i)   All rights of the Borrower to exercise the voting and
other consensual rights which it would otherwise be entitled to exercise
pursuant to Section 10(a) and to receive the dividends which it would otherwise
be authorized to receive and retain pursuant to Section 10(b) shall cease, and
all such rights shall, upon notice by the Lender to the Borrower, become vested
in the Lender, who shall thereupon have the sole right to exercise such voting
and other consensual rights and the sole right to receive and hold as
Collateral such dividends and apply them to payment of the Debt; and

                    (ii)  All dividends which are received by the Borrower 
contrary to the provisions of paragraph (i) of this Section 11(b) shall be
received in trust for the benefit of the Lender, shall be segregated from other
funds of the Borrower and shall be forthwith paid over to the Lender as
Collateral in the same form as so received (with any necessary indorsement).

          12.  Remedies Upon the Occurrence of an Event of Default.
               ----------------------------------------------------

                                     -7-
<PAGE>
 
               (a)  If an Event of Default specified under Section 11(a)(i) 
through Section 11(a)(iii) hereof shall occur and be continuing, the Lender may
by written notice to the Borrower, declare the unpaid principal amount of the
Note then outstanding and all interest accrued thereon, any unpaid fees and all
other obligations of the Borrower to the Lender hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be
immediately due and payable to the Lender without presentment, demand, protest
or any other notice of any kind, all of which are hereby expressly waived; and

               (b)  If an Event of Default specified under Section 11(a)(iv) 
through (v) shall occur, the Lender shall be under no further obligations to
make any Loan hereunder and the unpaid principal amount of the Note then
outstanding and all interest accrued thereon, any unpaid fees and all other
obligations of the Borrower to the Lender hereunder and thereunder shall be
immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived.

               (c)  If there shall have occurred an Event of Default under the 
terms of this Agreement, then the Lender shall have such rights and remedies
with respect to the Collateral or any part thereof and the proceeds thereof as
are provided by the Code and such other rights and remedies with respect
thereto which it may have at law or in equity or under this Agreement,
including without limitation, to the extent not inconsistent with the
provisions of the Code, the right to (i) transfer all or any part of the
Collateral into the Lender's name or into the name of its nominee and
thereafter receive all cash, stock and other dividends or distributions paid or
payable in respect thereof, and otherwise act with respect thereto as the
absolute owner thereof, and (ii) sell, assign, give an option or options to
purchase or otherwise dispose of all or any part of the Collateral at any sale
as provided by the Code at such place or places and at such time or times and
upon such terms, whether for cash or on credit, and in such manner as the
Lender may determine, and apply the proceeds so received (A) first to the
payment of the costs and expenses incurred by the Lender in connection with
such sale and other costs and expenses referred to in clauses (ii) and (iii) of
the definition of "Debt," (B) second to the repayment of all amounts then due
and unpaid on the Debt, whether on account of principal, interest, fees,
expenses or otherwise, and (C) then to pay the balance, if any, as required by
law.  The Borrower shall be liable for any deficiency if the proceeds of any
sale, assignment, giving of an option or options to purchase or other
disposition of the Collateral is insufficient to pay all amounts to which the
Lender is entitled.  Any excess proceeds from the sale, assignment, giving of
an option or options to purchase or other disposition of the Collateral after
payment of all amounts to which the Lender is entitled shall be paid to
Borrower.

          13.  Notice of Sale of the Collateral by the Lender.
               -----------------------------------------------

If any notification of intended sale of any of the Collateral is required by
law, such notification shall be deemed reasonable if mailed at least ten (10)
days before such sale, postage prepaid, addressed to the Borrower as provided in
Section 17 hereof.

          14.  Private Sale of the Collateral.
               -------------------------------

                                     -8-
<PAGE>
 
The Borrower recognizes that the Lender may be compelled to resort to one or
more private sales of the Collateral to a restricted group of purchasers who
will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Borrower acknowledges and agrees that any such private sale
may result in prices and other terms less favorable to the seller than if such
sale were a public sale and, notwithstanding such circumstances, agrees that any
such private sale shall not, for such reason alone, be deemed to have been made
in a commercially unreasonable manner.  The Lender shall not be under any
obligation to delay a sale of any of the Collateral for the period of time
necessary to permit the registration of such securities for public sale under
the Federal Securities Act of 1933, as amended, or under applicable state
securities laws.

          15.  Binding Effect; Termination.
               ----------------------------

Upon payment in full of the Debt, this Agreement shall terminate and be of no
further force and effect, and the Lender shall thereupon promptly return to the
Borrower such of the Collateral and such other documents delivered by the
Borrower hereunder as may then be in the Lender's possession.  Until such time,
however, this Agreement shall be binding upon and inure to the benefit of the
parties hereto, their respective successors and assigns.

          16.  Non-Waiver; Cumulative Remedies.
               --------------------------------

No failure or delay on the part of the Lender in exercising any right, remedy,
power or privilege hereunder shall operate as a waiver thereof or of any other
right, remedy, power or privilege of the Lender hereunder; nor shall any single
or partial exercise of any such right, remedy, power or privilege preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.  The rights and remedies of the Lender under this Agreement
are cumulative and not exclusive of any rights or remedies which it may
otherwise have.

          17.  Notices.
               --------

All notices and other communications which are required or may be given under
this Agreement shall be in writing and may be delivered by one of the following
methods of delivery:  (i) personally; (ii) by registered or certified mail,
return receipt requested, postage prepaid; (iii) by overnight courier; or (iv)

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

                                      -2-
<PAGE>
 
          The Lender hereby agrees to make a Loan to the Borrower, on the
Borrowing Date subject to and on the terms and conditions set forth herein, the
aggregate principal amount of which shall not exceed $1,000,000. The Loan is not
a revolving credit loan and the Borrower shall not have the right to borrow,
repay and reborrow hereunder. The obligation of the Borrower to repay the
principal amount of the Loan, together with interest thereon, shall be evidenced
by the Note duly executed and delivered by the Borrower with the blanks
appropriately completed. The entire unpaid principal balance of the Loan and
interest accrued thereon shall be due and paid in full on the Maturity Date. The
Borrower shall have the right at its option from time to time to prepay the Loan
in whole or in part. Any interest that accrues on the Loan from the date six
months after the date of the Loan shall be offset by bonus or additional
compensation payable to the Borrower by the Lender (the "Bonus Payment") which
payment shall be payable at the time the principal of and interest on the Loan
are due and payable, whether at the Maturity Date, by acceleration or otherwise.
In addition, the Lender shall make an additional payment (the "Gross-Up
Payment") to the Borrower in an amount equal to the Federal, state and local
income taxes payable by the Borrower with respect to the Bonus Payment. In
computing the Gross-Up Payment, the Bonus Payment shall be reduced by the
amount, if any, of the interest that accrued on the Loan from the date six
months after the date of the Loan that is deductible for Federal, state or local
tax purposes. After the Gross-Up Payment is so determined, the Borrower shall
also be entitled to receive additional payments in an amount such that after
payment by the Borrower of all Federal, state and local income taxes imposed
upon the Gross-Up Payment the Borrower shall retain an amount equal to the 
Gross-Up Payment.

               (b)    Interest Rate.
                      --------------

          The Note shall bear interest on the unpaid principal amount of the
Loan for each day (computed on the basis of the actual number of days elapsed
over a year of 365/366 days) at a rate per annum equal to the average rate at
which Lender is able to invest cash on a short-term basis from time to time.
Interest on the Loan shall be due and payable on the Maturity Date or upon
acceleration of the Note.

          3.   Pledge.
               -------

As security for the due and punctual payment and performance of the Debt in
full, the Borrower hereby agrees that the Lender shall have, and the Borrower
hereby grants to and creates in favor of the Lender, a first priority security
interest under the Code in and to all of the Collateral.

          4.   Delivery of Certificates, etc.
               ------------------------------

Upon the execution and delivery of this Agreement, the Borrower has delivered to

The Borrower represents and warrants to the Lender as follows:

               (a) The Borrower has good and marketable title to all of the
Collateral free and clear of any pledge, lien, security interest, encumbrance,
option or rights of others, except to the extent transfer of the Collateral may
be restricted by the Federal Securities Act of 1933, as amended, and state
securities laws and other than the security interest granted to and created in
favor of the Lender hereunder.

               (b) The Borrower (i) is an individual resident of Allegheny
County, Pennsylvania and has the legal capacity, power and authority to borrow
money, to execute and deliver the Note and this Agreement and to assign,
indorse, transfer and deliver, and pledge to Lender the Collateral and otherwise
perform its obligations as provided herein, and (ii) does not require the

governmental authority or other third party.

               (c) The execution, delivery and performance by the Borrower of
this Agreement, the Note and the other Loan Documents to which each is a party
are within the legal capacity and power of the Borrower, require no action by or
in respect of, or filing with, any governmental body, agency or official and do
not violate, contravene, or constitute a default under, any provision of any
applicable law or regulation, or of any agreement, judgment, injunction, order,
decree or other instrument binding upon the Borrower or his properties (except
to the extent that any required consent has been obtained) and will not result
in the creation or imposition of any lien on any asset of the Borrower except
for liens in favor of the Lender created hereunder.

               (d) This Agreement, the Note and the other Loan Documents
constitute valid and binding agreements and instruments of the Borrower,
enforceable against the Borrower in accordance with the terms thereof, except as
enforceability may be limited by bankruptcy, insolvency or similar laws
affecting creditors' rights generally or general principles of equity.

               (e) The Borrower is not in violation of or breach or default
under any provision of any law, rule or regulation, or any agreement, lease or
other instrument to which the Borrower is a party or by which he or his
properties are bound, which default would materially adversely affect the
Borrower's ability to repay the principal of and interest on the Loan and pledge
the Collateral hereunder.

               (f) There is no action, suit or proceeding pending or, to the
knowledge of the Borrower, threatened against or affecting the Borrower or any
of the Borrower's properties before any court, arbitrator or governmental body,
agency or official which would materially adversely affect the Borrower or the
Collateral.

          6.   Further Assurances.
               -------------------

<PAGE>
 
The Borrower will faithfully preserve and protect the Lender's security interest
in the Collateral as a first priority perfected security interest under the
Code, and will do all such other acts and things, and will upon request therefor
by the Lender execute and deliver all such other documents and instruments,
including, without limitation, further pledges, assignments, documents and
powers of attorney with respect to the Collateral consistent with the terms of
this Agreement, as the Lender in its sole discretion may deem necessary or
advisable from time to time in order to preserve, perfect and protect said
security interest.

          7.   Certain Covenants of the Borrower.
               ----------------------------------

The Borrower covenants and agrees that (a) he will defend the Lender's right,
title and security interest in and to the Collateral and the proceeds thereof
against the claims and demands of all persons whomsoever; (b) he will have like
title to and right to pledge any other property at any time hereafter pledged to
the Lender pursuant to this Agreement and will likewise defend the Lender's
right thereto and security interest therein; (c) he will not assign, transfer,
pledge, or otherwise encumber any of his right, title or interest under, in or
to the Collateral other than pursuant hereto; (d) he will not take or omit to

(g) he will promptly give notice in writing to the Lender of the occurrence of

the Borrower and any governmental or quasi-governmental authority  or any other
person (including, without limitation, any material changes in the federal
income tax filings of the Borrower which may be proposed on audit) if such
litigation, proceeding or dispute is one which would, if adversely determined,
have a material adverse effect on the Borrower or the Collateral.

          8.   Protection of the Lender's Interest in the Collateral Against
               -------------------------------------------------------------
Others.
- ------

The Borrower assumes full responsibility for taking any and all necessary steps
to preserve the Lender's rights with respect to the Collateral against all
others.  The Lender shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Lender takes
such action for that purpose as the Borrower shall request in writing, provided
that such requested action will not, in the judgment of the Lender, impair the
security interest in the Collateral created hereby or the Lender's rights in, or
the value of, the Collateral, and provided further that such written request is
received by the Lender in sufficient time to permit the Lender to take the
requested action.

          9.   Continuation of Perfection of Security Interest.
               ------------------------------------------------

The Borrower shall at the Borrower's own cost and expense cause the security
interest in the Collateral granted to and created in favor of the Lender under
this Agreement to be perfected and continue to be perfected as long as the Debt
or any part thereof is outstanding and unpaid or not

                                      -5-
<PAGE>
 
performed in full, and for such purpose the Borrower shall from time to time
deliver possession to the Lender of and execute, deliver and file or record (or
cause to be filed or recorded) such instruments, documents and notices
(including, without limitation, amendments or supplements to this Agreement,
financing statements and continuation statements) as the Lender may deem
necessary or advisable from time to time in order to confirm, perfect and
preserve such security interest. The Lender is hereby irrevocably appointed
attorney-in-fact of the Borrower to do all acts and things which the Lender, in
the exercise of its responsibilities under this Agreement, may deem necessary or
advisable to perfect and continue perfected the Lender's security interest in
the Collateral.

          10.  Voting Rights; Dividends; etc.

               (a) The Borrower shall be entitled to exercise any and all voting
and other consensual rights pertaining to the Collateral or any part thereof for

such right if such action or inaction would reasonably be likely to have a
material adverse effect on the value of the Collateral or any part thereof; and
provided, further, that the Borrower shall give the Lender at least five (5)
- -----------------
business days' written notice of the manner in which it intends to exercise, and
the reasons therefor, or the reasons for refraining from exercising, any such
right;

               (b) Any and all instruments and other property (other than cash
dividends) received, receivable or otherwise distributed in respect of, or in
exchange for, any of the Collateral shall be forthwith delivered to the Lender
to hold as part of the Collateral and shall, if received by the Borrower, be
received in trust for the benefit of the Lender, be segregated from the other
property or funds of the Borrower, and be forthwith delivered to the Lender as
Collateral in the same form as so received (with any necessary indorsement); and

               (c) The Lender shall execute and deliver (or cause to be executed
and delivered) to the Borrower all such proxies and other instruments as the
Borrower may reasonably request for the purpose of enabling the Borrower to
exercise the voting and other rights which he is entitled to exercise pursuant
to paragraph (a) above, and to receive the dividends which he is authorized to
receive and retain pursuant to paragraph (b) above.

relief or to the appointment of or taking possession by any such official in an
involuntary case or other proceeding commenced against him, or shall make a
general assignment for the benefit of creditors, or shall fail generally to pay
his debts as they become due, or shall take any action to authorize any of the
foregoing; or

                    (v) an involuntary case or other proceeding shall be

all such rights shall, upon notice by the Lender to the Borrower, become vested
in the Lender, who shall thereupon have the sole right to exercise such voting
and other consensual rights and the sole right to receive and hold as Collateral
such dividends and apply them to payment of the Debt; and

                    (ii) All dividends which are received by the Borrower
contrary to the provisions of paragraph (i) of this Section 11(b) shall be
received in trust for the benefit of the Lender, shall be segregated from other
funds of the Borrower and shall be forthwith paid over to the Lender as
Collateral in the same form as so received (with any necessary indorsement).

           12. Remedies Upon the Occurrence of an Event of Default.
               ----------------------------------------------------

                                      -7-
<PAGE>
 
                    (a) If an Event of Default specified under Section 11(a)(i)
through Section 11(a)(iii) hereof shall occur and be continuing, the Lender may
by written notice to the Borrower, declare the unpaid principal amount of the
Note then outstanding and all interest accrued thereon, any unpaid fees and all
other obligations of the Borrower to the Lender hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be
immediately due and payable to the Lender without presentment, demand, protest
or any other notice of any kind, all of which are hereby expressly waived; and

                    (b) If an Event of Default specified under Section 11(a)(iv)
through (v) shall occur, the Lender shall be under no further obligations to
make any Loan hereunder and the unpaid principal amount of the Note then
outstanding and all interest accrued thereon, any unpaid fees and all other
obligations of the Borrower to the Lender hereunder and thereunder shall be
immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived.

                    (c) If there shall have occurred an Event of Default under
the terms of this Agreement, then the Lender shall have such rights and remedies
with respect to the Collateral or any part thereof and the proceeds thereof as
are provided by the Code and such other rights and remedies with respect thereto
which it may have at law or in equity or under this Agreement, including without
limitation, to the extent not inconsistent with the provisions of the Code, the
right to (i) transfer all or any part of the Collateral into the Lender's name
or into the name of its nominee and thereafter receive all cash, stock and other
dividends or distributions paid or payable in respect thereof, and otherwise act
with respect thereto as the absolute owner thereof, and (ii) sell, assign, give
an option or options to purchase or otherwise dispose of all or any part of the
Collateral at any sale as provided by the Code at such place or places and at
such time or times and upon such terms, whether for cash or on credit, and in
such manner as the Lender may determine, and apply the proceeds so received (A)
first to the payment of the costs and expenses incurred by the Lender in
connection with such sale and other costs and expenses referred to in clauses
(ii) and (iii) of the definition of "Debt," (B) second to the repayment of all
amounts then due and unpaid on the Debt, whether on account of principal,
interest, fees, expenses or otherwise, and (C) then to pay the balance, if any,
as required by law. The Borrower shall be liable for any deficiency if the
proceeds of any sale, assignment, giving of an option or options to purchase or
other disposition of the Collateral is insufficient to pay all amounts to which
the Lender is entitled. Any excess proceeds from the sale, assignment, giving of
an option or options to purchase or other disposition of the Collateral after
payment of all amounts to which the Lender is entitled shall be paid to
Borrower.

          13.  Notice of Sale of the Collateral by the Lender.
               -----------------------------------------------

If any notification of intended sale of any of the Collateral is required by
law, such notification shall be deemed reasonable if mailed at least ten (10)
days before such sale, postage prepaid, addressed to the Borrower as provided in
Section 17 hereof.

          14.  Private Sale of the Collateral.
               -------------------------------

                                      -8-
<PAGE>
 
The Borrower recognizes that the Lender may be compelled to resort to one or
more private sales of the Collateral to a restricted group of purchasers who
will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Borrower acknowledges and agrees that any such private sale
may result in prices and other terms less favorable to the seller than if such
sale were a public sale and, notwithstanding such circumstances, agrees that any
such private sale shall not, for such reason alone, be deemed to have been made
in a commercially unreasonable manner.  The Lender shall not be under any
obligation to delay a sale of any of the Collateral for the period of time
necessary to permit the registration of such securities for public sale under
the Federal Securities Act of 1933, as amended, or under applicable state
securities laws.

          15.  Binding Effect; Termination.
               ----------------------------

Upon payment in full of the Debt, this Agreement shall terminate and be of no
further force and effect, and the Lender shall thereupon promptly return to the
Borrower such of the Collateral and such other documents delivered by the
Borrower hereunder as may then be in the Lender's possession. Until such time,
however, this Agreement shall be binding upon and inure to the benefit of the
parties hereto, their respective successors and assigns.

          16.  Non-Waiver; Cumulative Remedies.
               --------------------------------

No failure or delay on the part of the Lender in exercising any right, remedy,
power or privilege hereunder shall operate as a waiver thereof or of any other
right, remedy, power or privilege of the Lender hereunder; nor shall any single
or partial exercise of any such right, remedy, power or privilege preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights and remedies of the Lender under this Agreement
are cumulative and not exclusive of any rights or remedies which it may
otherwise have.

          17.  Notices.
               --------

All notices and other communications which are required or may be given under
this Agreement shall be in writing and may be delivered by one of the following

  the number of Warrant Shares referred to above in the first recital hereof and

  of the Warrant Certificates as the absolute owner(s) thereof (notwithstanding
  any notation of ownership or other writing thereon made by anyone), for all
  purposes, and neither the Company nor the Warrant Agent shall be affected by
  any notice to the contrary.  Prior to a Separation Date, the registered holder
  of the Unit shall be deemed the registered Holder of such Warrants for all
  purposes hereunder.

                 Securities Act (and based on an opinion of counsel if the
                 Company so requests), a certification to that effect (in

             for the Depositary from the Depositary or its nominee on behalf of
             any person having a beneficial interest in a Global Warrant and,
             in the case of a Registrable Security, the following additional
             information and documents (all of which may be submitted by
             facsimile):

             (A) if such beneficial interest is being delivered to the person 
                 designated by the Depositary as being the beneficial owner, a
                 certification to that effect (in substantially the form of
                 Exhibit B hereto);

             (B) if such beneficial interest is being transferred (1) to a 
                 "qualified institutional buyer" (as defined in Rule 144A under
                 the Securities Act) in accordance with 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 to an effective registration
                 statement under the Securities Act, a certification to that
                 effect (in substantially the form of Exhibit B hereto);

             (C) if such beneficial interest is being transferred to any
                 institutional "accredited investor," within the meaning of
                 Rule 501(a)(1), (2), (3) and (7) under the Securities Act
                 pursuant to a private placement exemption from the

                 certification to that effect (in substantially the form of
                 Exhibit B hereto) and a certification from the applicable
                 transferee;

             (D) 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 (in
                 substantially the form of Exhibit B hereto).

             then the Warrant Agent shall cause, in accordance with the
             standing instructions and procedures existing between the
             Depositary and Warrant Agent, the number of Warrants and Warrant
             Shares represented by the Global Warrant to be reduced and,
             following such reduction, the Company shall execute and the
             Warrant Agent shall countersign and deliver to the transferee, as
             the case may be, a Definitive Warrant.

        (ii) Definitive Warrants issued in exchange for a beneficial interest 
             in a Global Warrant pursuant to this Section 7(d) shall be
             registered in such names as the Depositary, pursuant to
             instructions from its direct or indirect participants or
             otherwise, shall instruct the Warrant Agent.  The Warrant Agent
             shall deliver such Definitive Warrants to the persons in whose
             names such Warrants are so registered.

             (e) Restrictions on Transfer and Exchange of Global Warrants.
                 --------------------------------------------------------  
  Notwithstanding any other provisions of this Warrant Agreement (other than the
  provisions set forth in subsection (f) of this Section 7), a Global Warrant
  may not be transferred as a whole except 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.

             (f) Countersigning of Definitive Warrants in Absence of Depositary.
                 --------------------------------------------------------------
  If at any time:

        (i)  the Depositary for the Global Warrants notifies the Company that 
             the Depositary is unwilling or unable to continue as Depositary
             for the Global Warrants and a successor Depositary for the Global
             Warrants is not appointed by the Company within 90 days after
             delivery of such notice; or

        (ii) The Company, in its sole discretion, notifies the Warrant Agent in
             writing that it elects to cause the issuance of Definitive
             Warrants under this Warrant Agreement,

  then the Company shall execute, and the Warrant Agent, upon written
  instructions signed by two officers of the Company, shall countersign and
  deliver Definitive Warrants, in an aggregate number equal to the number of
  Warrants represented by Global Warrants, in exchange for such Global Warrants.

             (g) Legends.
                 ------- 

        (i)  Except for any Registrable Security sold or transferred (including
             any Registrable Security represented by a Global Warrant) as
             discussed in clause (ii) below, each Warrant Certificate
             evidencing the Global Warrants and the Definitive Warrants (and
             all Warrants issued in exchange therefor or substitution thereof)
             and each certificate representing the Warrant Shares shall bear a
             legend in substantially the following form:

                 OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
                 AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE
                 SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER
                 MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION
                 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.  BY
                 ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT
                 IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A

                 INVESTOR").  THE HOLDER OF THE SECURITY EVIDENCED HEREBY
                 AGREES FOR THE BENEFIT OF THE COMPANY THAT (Y) SUCH SECURITY
                 MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a)
                 TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED

                 SECURITIES ACT), IN A TRANSACTION MEETING THE REQUIREMENTS OF
                 RULE 144A, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF
                 RULE 144 UNDER THE SECURITIES ACT, (c) IN ACCORDANCE WITH
                 ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE

                 LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE
                 JURISDICTION AND (Z) IT WILL NOTIFY ANY PURCHASER OF THE

                 THE RESALE RESTRICTIONS SET FORTH IN (Y) ABOVE."

        (ii) Upon any sale or transfer of a Registrable Security (including any
             Registrable Security represented by a Global Warrant) 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 that no
             legend is required:

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

             (B) in the case of any Registrable Security represented by a 
                 Global Warrant, such Registrable Security shall not be
                 required to bear the legend set forth in clause (i) above but
                 shall continue to be subject to the provisions of Section 7(c)
                 hereof; provided that with respect to any request for an
                 exchange of a

<PAGE>
 
                 Registrable Security that is represented by a Global Warrant
                 for a Definitive Warrant that does not bear the legend set
                 forth in clause (i) above, which request is made in reliance
                 upon Rule 144 (and based on an opinion of counsel if the
                 Company so requests), the Holder thereof shall certify in
                 writing to the Warrant Agent that such request is being made
                 pursuant to Rule 144 (such certification to be substantially
                 in the form of Exhibit B hereto).

             (h) Cancellation of Global Warrant.  At such time as all beneficial
                 ------------------------------                                 
  interests in Global Warrants have either been exchanged for Definitive
  Warrants, redeemed, repurchased or cancelled, all Global Warrants shall be
  returned to or retained and cancelled by the Warrant Agent.

             (i) Obligations with respect to Transfers and Exchanges of 
                 ------------------------------------------------------
                 Warrants.
                 -------- 

        (i)   To permit registrations of transfers and exchanges, the Company 
              shall execute and the Warrant Agent is hereby authorized to
              countersign, in accordance with the provisions of Section 6 and
              this Section 7, Definitive Warrants and Global Warrants as
              required pursuant to the provisions of this Section 7.

        (ii)  All Definitive Warrants and Global Warrants issued upon any 
              registration of transfer or exchange of Definitive Warrants or
              Global Warrants shall be the valid obligations of the Company,
              entitled to the same benefits under this Warrant Agreement, as the
              Definitive Warrants or Global Warrants surrendered upon such
              registration of transfer or exchange.

        (iii) Prior to due presentment for registration of transfer of any 
              Warrant, the Warrant Agent and the Company may deem and treat the
              person in whose name any Warrant is registered as the absolute
              owner of such Warrant and neither the Warrant Agent, nor the
              Company shall be affected by notice to the contrary.

        (iv)  No service charge shall be made to a Holder for any registration,
              transfer or exchange.


             SECTION 8.  Terms of Warrants; Exercise of Warrants.  Subject to 
                         ---------------------------------------
  the terms of this Agreement, each Warrant Holder shall have the right, which
  may be exercised commencing at the opening of business on the Exercisability
  Date and until 5:00 p.m., New York City time on the Expiration Date to
  receive from the Company the number of fully paid and nonassessable Warrant
  Shares registered under the Securities Act which the Holder may at the time
  be entitled to receive on exercise of such Warrants and payment of the
  Exercise Price then in effect for such Warrant Shares; provided that no
  Warrant Holder shall be entitled to exercise such Holder's Warrants at any
  time, unless, at the time of exercise, (i) a registration statement under the
  Securities Act relating to the Warrant Shares has been filed with, and
  declared effective by, the Commission, and no stop order suspending the
  effectiveness of such registration statement has been issued by the
  Commission or (ii) the issuance of the Warrant Shares is permitted pursuant
  to an exemption from the registration requirements of the Securities Act. 
  Each Warrant not exercised prior to 5:00 p.m., New York City time, on the
  Expiration Date shall become void and all rights thereunder and all rights in
  respect thereof under this Agreement shall cease as of such time.  No
  adjustments as to dividends will be made upon exercise of the Warrants.

                                      9
<PAGE>
 
            The Company shall give notice not less than 90, and not more than
  120, days prior to the Expiration Date to the Holders of all then outstanding
  Warrants to the effect that the Warrants will terminate and become void as of
  the 5:00 p.m., New York City time, on the Expiration Date.  If the Company
  fails to give such notice, the Warrants will not expire until 90 days after
  the Company gives such notice, provided in no event will Holders be entitled
  to any damages or other remedy for the Company's failure to give such notice
  other than any such extension.

            A Warrant may be exercised upon surrender to the Company at the
  principal office of the Warrant Agent of the certificate or certificates
  evidencing the Warrant to be exercised with the form of election to purchase
  on the reverse thereof duly filled in and signed, which signature shall be
  guaranteed by a bank or trust company having an office or correspondent in the
  United States or a broker or dealer which is a member of a registered
  securities exchange or the National Association of Securities Dealers, Inc.,
  and upon payment to the Warrant Agent for the account of the Company of the
  Exercise Price as adjusted as herein provided, for each of the Warrant Shares
  in respect of which such Warrant is then exercised.  Payment of the aggregate
  Exercise Price shall be made in cash or by certified or official bank check,
  payable to the order of the Company.  In the alternative, each Holder may
  exercise its right to receive Warrant Shares on a net basis, such that without
  the exchange of any funds, the Holder receives that number of Warrant Shares
  otherwise issuable upon exercise of its Warrants less that number of Warrant
  Shares having a fair market value equal to the aggregate Exercise Price that
  would otherwise have been paid by the Holder of the Warrant Shares.  For
  purposes of the foregoing sentence, "fair market value" of the Warrant Shares
  shall be the current market price of the Warrant Shares on the date
  immediately preceding the date of payment of the Exercise Price as determined
  by the procedures set forth in Section 13(f).  The exercise of Warrants by
  Holders of beneficial interest in Global Warrants shall be effected in
  accordance with this Agreement and the procedures of the Depositary therefor.

            Subject to the provisions of Section 9 hereof, upon surrender of
  Warrants and payment of the Exercise Price as provided above, the Warrant
  Agent shall thereupon promptly notify the Company, and the Company shall
  promptly transfer to the Holder of such Warrant Certificate a certificate or
  certificates for the appropriate number of Warrant Shares or other securities
  or property (including any money) to which the Holder is entitled, registered
  or otherwise placed in, or payable to the order of, such name or names as may
  be directed in writing by the Holder, and shall deliver such certificate or
  certificates representing the Warrant Shares and any other securities or
  property (including any money) to the person or persons entitled to receive
  the same, together with an amount in cash in lieu of any fraction of a share
  as provided in Section 15.  Any such certificate or certificates representing
  the Warrant Shares shall be deemed to have been issued and any person so
  designated to be named therein shall be deemed to have become a Holder of
  record of such Warrant Shares as of the date of the surrender of such Warrants
  and payment of the Exercise Price.

            The Warrants shall be exercisable commencing on the Exercisability
  Date, at the election of the Holders thereof, either in full or from time to
  time in part and, in the event that a certificate evidencing Warrants is
  exercised in respect of fewer than all of the Warrant Shares issuable on such
  exercise at any time prior to the date of expiration of the Warrants, a new
  certificate evidencing the remaining Warrant or Warrants will be issued, and
  the Warrant Agent is hereby irrevocably authorized to countersign and to
  deliver the required new Warrant Certificate or Certificates pursuant to the
  provisions of this Section and of Section 4 hereof, and the Company, whenever
  required by the

                                      10
<PAGE>
 
  Warrant Agent, will supply the Warrant Agent with Warrant Certificates duly
  executed on behalf of the Company for such purpose.

            All Warrant Certificates surrendered upon exercise of Warrants shall
  be cancelled by the Warrant Agent.  Such cancelled Warrant Certificates shall
  then be disposed of by the Warrant Agent in a manner satisfactory to the
  Company. The Warrant Agent shall account promptly to the Company with respect
  to Warrants exercised and concurrently pay to the Company all monies received
  by the Warrant Agent for the purchase of the Warrant Shares through the
  exercise of such Warrants.

            The Warrant Agent shall keep copies of this Agreement and any
  notices given or received hereunder by or from the Company available for
  inspection by the Holders during normal business hours at its office.  The
  Company shall supply the Warrant Agent from time to time with such numbers of
  copies of this Agreement as the Warrant Agent may request.

            SECTION 9.  Payment of Taxes.  The Company will pay all documentary
                        ----------------                                       
  stamp taxes attributable to the initial issuance of Warrant Shares upon the
  exercise of Warrants or to any Separation; provided that the Company shall not
  be required to pay any tax or taxes which may be payable in respect of any
  transfer involved in the issue of any Warrant Certificates or any certificates
  for Warrant Shares in a name other than that of the Holder of a Warrant
  Certificate surrendered upon the exercise of a Warrant, and the Company shall
  not be required to issue or deliver such Warrant Certificates unless or until
  the person or persons requesting the issuance thereof shall have paid to the
  Company the amount of such tax or shall have established to the satisfaction
  of the Company that such tax has been paid.

            SECTION 10.  Mutilated or Missing Warrant Certificates.  In case any
                         -----------------------------------------              
  of the Warrant Certificates shall be mutilated, lost, stolen or destroyed, the
  Company may in its discretion issue and the Warrant Agent may countersign, in
  exchange and substitution for and upon cancellation of the mutilated Warrant
  Certificate, or in lieu of and substitution for the Warrant Certificate lost,
  stolen or destroyed, a new Warrant Certificate of like tenor and representing
  an equivalent number of Warrants, but only upon receipt of evidence reasonably
  satisfactory to the Company and the Warrant Agent of such loss, theft or
  destruction of such Warrant Certificate and indemnity, if requested, also
  reasonably satisfactory to them.  Applicants for such substitute Warrant
  Certificates shall also comply with such other reasonable regulations and pay
  such other reasonable charges as the Company or the Warrant Agent may
  prescribe.

            SECTION 11.  Reservation of Warrant Shares.  The Company will at all
                         -----------------------------                          
  times reserve and keep available, free from preemptive rights, out of the
  aggregate of its authorized but unissued Common Stock or its authorized and
  issued Common Stock held in its treasury, for the purpose of enabling it to
  satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the
  maximum number of shares of Common Stock which may then be deliverable upon
  the exercise of all outstanding Warrants.

            The transfer agent for the Common Stock (the "Transfer Agent") and
  every subsequent transfer agent for any shares of the Company's capital stock
  issuable upon the exercise of any of the rights of purchase aforesaid will be
  irrevocably authorized and directed at all times to reserve such number of
  authorized shares as shall be required for such purpose. The Company will keep
  a copy of this Agreement on file with the Transfer Agent and with every
  subsequent transfer agent for any

                                      11
<PAGE>
 
  shares of the Company's capital stock issuable upon the exercise of the rights
  of purchase represented by the Warrants.  The Warrant Agent is hereby
  irrevocably authorized to requisition from time to time from such Transfer
  Agent the stock certificates required to honor outstanding Warrants upon
  exercise thereof in accordance with the terms of this Agreement.  The Company
  will supply such Transfer Agent with duly executed certificates for such
  purposes and will provide or otherwise make available any cash which may be
  payable as provided in Section 15.  The Company will furnish such Transfer
  Agent a copy of all notices of adjustments and certificates related thereto,
  transmitted to each Holder of the Warrants pursuant to Section 16 hereof.

            Before taking any action which would cause an adjustment pursuant to
  Section 13 hereof to reduce the Exercise Price below the then par value (if
  any) of the Warrant Shares, the Company will take any corporate action which
  may, in the opinion of its counsel (which may be counsel employed by the
  Company), be necessary in order that the Company may validly and legally issue
  fully paid and nonassessable Warrant Shares at the Exercise Price as so
  adjusted.

            The Company covenants that all Warrant Shares which may be issued
  upon exercise of Warrants in accordance with the terms of this Agreement
  (including the terms of the Exercise Price) will, upon issue, be duly and
  validly issued, fully paid, nonassessable, free of preemptive rights and free
  from all taxes, liens, charges and security interests with respect to the
  issue thereof.

            SECTION 12.  Obtaining Stock Exchange Listings.  The Company will
                         ---------------------------------                   
  from time to time take all action which may be necessary so that the Warrant
  Shares, immediately upon their issuance upon the exercise of Warrants, will be
  listed on the principal securities exchanges and markets (including, without
  limitation, the Nasdaq National Market) within the United States of America,
  if any, on which other shares of Common Stock are then listed.  Upon the
  listing of such Warrant Shares, the Company shall notify the Warrant Agent in
  writing.  The Company will obtain and keep all required permits and records in
  connection with such listing.

            SECTION 13.  Adjustment of Exercise Price and Number of Warrant
                         --------------------------------------------------
  Shares Issuable. The number and kind of shares purchasable upon the exercise
  ---------------                                                             
  of Warrants and the Exercise Price shall be subject to adjustment from time to
  time as follows:

            (a) Stock Splits, Combinations, etc.  In case the Company shall
                -------------------------------                            
  hereafter (A) pay a dividend or make a distribution on its Common Stock in
  shares of its capital stock (whether shares of Common Stock or of capital
  stock of any other class), (B) subdivide its outstanding shares of Common
  Stock, (C) combine its outstanding shares of Common Stock into a smaller
  number of shares or (D) issue by reclassification of its shares of Common
  Stock any shares of capital stock of the Company, the Exercise Price in effect
  immediately prior to such action shall be adjusted so that the Holder of any
  Warrant thereafter exercised shall be entitled to receive the number of shares
  of capital stock of the Company which such Holder would have owned immediately
  following such action had such Warrant been exercised immediately prior
  thereto.  An adjustment made pursuant to this paragraph shall become effective
  immediately after the record date in the case of a dividend and shall become
  effective immediately after the effective date in the case of a subdivision,
  combination or reclassification.  If, as a result of an adjustment made
  pursuant to this paragraph, the Holder of any Warrant thereafter exercised
  shall become entitled to receive shares of two or more classes of capital
  stock of the Company, the Board of Directors of the Company (whose
  determination shall be conclusive) shall

                                      12
<PAGE>
 
  determine the allocation of the adjusted Exercise Price between or among
  shares of such classes of capital stock.

            (b) Reclassification, Combinations, Mergers, etc.  In case of any
                --------------------------------------------                 
  reclassification or change of outstanding shares of Common Stock issuable upon
  exercise of the Warrants (other than as set forth in paragraph (a) above and
  other than a change in par value, or from par value to no par value, or from
  no par value to par value or as a result of a subdivision or combination), or
  in case of any consolidation or merger of the Company with or into another
  corporation (other than a merger in which the Company is the continuing
  corporation and which does not result in any reclassification or change of the
  then outstanding shares of Common Stock or other capital stock issuable upon
  exercise of the Warrants) or in case of any sale or conveyance to another
  corporation of the property of the Company as an entirety or substantially as
  an entirety, then, as a condition of such reclassification, change,
  consolidation, merger, sale or conveyance, the Company or such a successor or
  purchasing corporation, as the case may be, shall forthwith make lawful and
  adequate provision whereby the Holder of such Warrant then outstanding shall
  have the right thereafter to receive on exercise of such Warrant the kind and
  amount of shares of stock and other securities and property receivable upon
  such reclassification, change, consolidation, merger, sale or conveyance by a
  Holder of the number of shares of Common Stock issuable upon exercise of such
  Warrant immediately prior to such reclassification, change, consolidation,
  merger, sale or conveyance and enter into a supplemental warrant agreement so
  providing.  Such provisions shall include provision for adjustments which
  shall be as nearly equivalent as may be practicable to the adjustments
  provided for in this Section 13.  If the issuer of securities deliverable upon
  exercise of Warrants under the supplemental warrant agreement is an affiliate
  of the formed, surviving or transferee corporation, that issuer shall join in
  the supplemental warrant agreement.  The above provisions of this paragraph
  (b) shall similarly apply to successive reclassifications and changes of
  shares of Common Stock and to successive consolidations, mergers, sales or
  conveyances.

            (c) Issuance of Options or Convertible Securities.  In the event the
                ---------------------------------------------                   
  Company shall, at any time or from time to time after the date hereof, issue,
  sell, distribute or otherwise grant in any manner (including by assumption) to
  all holders of the Common Stock any rights to subscribe for or to purchase, or
  any warrants or options for the purchase of, Common Stock or any stock or
  securities convertible into or exchangeable for Common Stock (any such rights,
  warrants or options being herein called "Options" and any such convertible or
  exchangeable stock or securities being herein called "Convertible Securities")
  or any Convertible Securities (other than upon exercise of any Option),
  whether or not such Options or the rights to convert or exchange such
  Convertible Securities are immediately exercisable, and the price per share at
  which Common Stock is issuable upon the exercise of such Options or upon the
  conversion or exchange of such Convertible Securities (determined by dividing
  (i) the aggregate amount, if any, received or receivable by the Company as
  consideration for the issuance, sale, distribution or granting of such Options
  or any such Convertible Security, plus the minimum aggregate amount of
  additional consideration, if any, payable to the Company upon the exercise of
  all such Options or upon conversion or exchange of all such Convertible
  Securities, plus, in the case of Options to acquire Convertible Securities,
  the minimum aggregate amount of additional consideration, if any, payable upon
  the conversion or exchange of all such Convertible Securities, by (ii) the
  total maximum number of shares of Common Stock issuable upon the exercise of
  all such Options or upon the conversion or exchange of all such Convertible
  Securities or upon the conversion or exchange of all Convertible Securities
  issuable upon the exercise of all such Options) shall be less than the current
  market price per share of Common Stock on the record date for the issuance,
  sale,

                                      13
<PAGE>
 
  distribution or granting of such Options or Convertible Securities (any such
  event being herein called a "Distribution"), then, effective upon such
  Distribution, (I) the Exercise Price shall be reduced to the price (calculated
  to the nearest 1/1,000 of one cent) determined by multiplying the Exercise
  Price in effect immediately prior to such Distribution by a fraction, the
  numerator of such shall be the sum of (1) the number of shares of Common Stock
  outstanding (exclusive of any treasury shares) immediately prior to such
  Distribution multiplied by the current market price per share of Common Stock
  on the date of such Distribution plus (2) the consideration, if any, received
  by the Company upon such Distribution, and the denominator of which shall be
  the product of (A) the total number of shares of Common Stock outstanding
  (exclusive of any treasury shares) immediately after such Distribution
  multiplied by (B) the current market price per share of Common Stock on the
  record date for such Distribution and (II) the number of shares of Common
  Stock purchasable upon the exercise of each Warrant shall be increased to a
  number determined by multiplying the number of shares of Common Stock so
  purchasable immediately prior to the record date for such Distribution by a
  fraction, the numerator of which shall be the Exercise Price in effect
  immediately prior to the adjustment required by clause (I) of this sentence
  and the denominator of which shall be the Exercise Price in effect immediately
  after such adjustment (for the purposes of this clause (ii) without giving
  effect to the provisions of Section 13(h)).  For purposes of the foregoing,
  the total maximum number of shares of Common Stock issuable upon exercise of
  all such Options or upon conversion or exchange of all such Convertible
  Securities or upon the conversion or exchange of the total maximum amount of
  the Convertible Securities issuable upon the exercise of all such Options
  shall be deemed to have been issued as of the date of such Distribution and
  thereafter shall be deemed to be outstanding and the Company shall be deemed
  to have received as consideration therefor such price per share, determined as
  provided above.  Except as provided in paragraphs (j) and (k) below, no
  additional adjustment of the Exercise Price shall be made upon the actual
  exercise of such Options or upon conversion or exchange of the Convertible
  Securities or upon the conversion or exchange of the Convertible Securities
  issuable upon the exercise of such Options.

            (d) Dividends and Distributions.  In the event the Company shall, at
                ---------------------------                                     
  any time or from time to time after the date thereof, distribute to all the
  holders of Common Stock any dividend or other distribution of cash, evidences
  of its indebtedness, other securities or other properties or assets (in each
  case other than (i) dividends payable in Common Stock, Options or Convertible
  Securities and (ii) any cash dividend that, when added to all other cash
  dividends paid in the one year prior to the declaration date of such dividend
  (excluding any such other dividend included in a previous adjustment of the
  Exercise Price pursuant to this paragraph (d)), does not exceed 5% of the
  current market price per share of Common Stock on such declaration date), or
  any options, warrants or other rights to subscribe for or purchase any of the
  foregoing, then (A) the Exercise Price shall be decreased to a price
  determined by multiplying the Exercise Price then in effect by a fraction, the
  numerator of which shall be the current market price per share of Common Stock
  on the record date for such distribution less the sum of (X) the cash portion,
  if any, of such distribution per share of Common Stock outstanding (exclusive
  of any treasury shares) on the record date for such distribution plus (Y) the
  then fair market value (as determined in good faith by the Board of Directors
  of the Company) per share of Common Stock outstanding (exclusive of any
  treasury shares) on the record date for such distribution of that portion, if
  any, of such distribution consisting of evidences of indebtedness, other
  securities, properties, assets, options, warrants or subscription or purchase
  rights, and the denominator of which shall be such current market price per
  share of Common Stock and (B) the number of shares of Common Stock purchasable
  upon the exercise of each Warrant shall be increased to a number determined by
  multiplying the number of shares of Common Stock so purchasable immediately
  prior to the record date for such distribution by a fraction, the numerator of
  which shall be the Exercise Price in effect immediately prior to the

                                      14
<PAGE>
 
  adjustment required by clause (A) of this sentence and the denominator of
  which shall be the Exercise Price in effect immediately after such adjustment
  (for the purposes of this clause (B) without giving effect to the provisions
  of Section 13(h)).  The adjustments required by this paragraph (d) shall be
  made whenever any such distribution occurs retroactive to the record date for
  the determination of stockholders entitled to receive such distribution.

            (e) Current Market Price.  For the purpose of any computation of
                --------------------                                        
  current market price under this Section 13 and Section 15, the current market
  price per share of Common Stock at any date shall be (x) for purposes of
  Section 15, the closing price on the business day immediately prior to the
  exercise of the applicable Warrant pursuant to Section 8 and (y) in all other
  cases, the average of the daily closing prices for the shorter of (i) the 20
  consecutive trading days ending on the last full trading day on the exchange
  or market specified in the second succeeding sentence prior to the Time of
  Determination (as defined below) and (ii) the period commencing on the date
  next succeeding the first public announcement of the issuance, sale,
  distribution or granting in question through such last full trading day prior
  to the Time of Determination.  The term "Time of Determination" as used herein
  shall be the time and date of the earlier to occur of (A) the date as of which
  the current market price is to be computed and (B) the last full trading day
  on such exchange or market before the commencement of "ex-dividend" trading in
  the Common Stock relating to the event giving rise to the adjustment required
  by paragraph (a), (b), (c) or (d).  The closing price for any day shall be the
  last reported sale price regular way or, in case no such reported sale takes
  place on such day, the average of the closing bid and asked prices regular way
  for such day, in each case (1) on the principal national securities exchange
  on which the shares of Common Stock are listed or to which such shares are
  admitted to trading or (2) if the Common Stock is not listed or admitted to
  trading on a national securities exchange, in the over-the-counter market as
  reported by Nasdaq National Market or any comparable system or (3) if the
  Common Stock is not listed on Nasdaq National Market or a comparable system,
  as furnished by two members of the NASD selected from time to time in good
  faith by the Board of Directors of the Company for that purpose.  In the
  absence of all of the foregoing, or if for any other reason the current market
  price per share cannot be determined pursuant to the foregoing provisions of
  this paragraph (e), the current market price per share shall be the fair
  market value thereof as determined in good faith by the Board of Directors of
  the Company.

            (f) Certain Distributions.  If the Company shall pay a dividend or
                ---------------------                                         
  make any other distribution payable in Options or Convertible Securities,
  then, for purposes of paragraph (c) above, such Options or Convertible
  Securities shall be deemed to have been issued or sold without consideration.

            (g) Consideration Received.  If any shares of Common Stock, Options
                ----------------------                                         
  or Convertible Securities shall be issued, sold or distributed for a
  consideration other than cash, the amount of the consideration other than cash
  received by the Company in respect thereof shall be deemed to be the then fair
  market value of such consideration (as determined in good faith by the Board
  of Directors of the Company).  If any Options shall be issued in connection
  with the issuance and sale of other securities of the Company, together
  comprising one integral transaction in which no specific consideration is
  allocated to such Options by the parties thereto, such Options shall be deemed
  to have been issued without consideration; provided, that if such Options have
  an exercise price equal to or greater than the current market price of the
  Common Stock on the date of issuance of such Options, then such Options shall
  be deemed to have been issued for consideration equal to such exercise price.

                                      15
<PAGE>
 
            (h) Deferral of Certain Adjustments.  No adjustment to the Exercise
                -------------------------------                                
  Price (including the related adjustment to the number of shares of Common
  Stock purchasable upon the exercise of each Warrant) shall be required
  hereunder unless such adjustment, together with other adjustments carried
  forward as provided below, would result in an increase or decrease of at least
  one percent of the Exercise Price; provided that any adjustments which by
  reason of this paragraph (i) are not required to be made shall be carried
  forward and taken into account in any subsequent adjustment. No adjustment
  need be made for a change in the par value of the Common Stock.  All
  calculations under this Section shall be made to the nearest 1/1,000 of one
  cent or to the nearest 1/1000 of a share, as the case may be.

            (i) Changes in Options and Convertible Securities.  If the exercise
                ---------------------------------------------                  
  price provided for in any Options referred to in paragraph (c) above, the
  additional consideration, if any, payable upon the conversion or exchange of
  any Convertible Securities referred to in paragraph (c) above, or the rate at
  which any Convertible Securities referred to in paragraph (c) above are
  convertible into or exchangeable for Common Stock shall change at any time
  (other than under or by reason of provisions designed to protect against
  dilution upon an event which results in a related adjustment pursuant to this
  Section 13), the Exercise Price then in effect and the number of shares of
  Common Stock purchasable upon the exercise of each Warrant shall forthwith be
  readjusted (effective only with respect to any exercise of any Warrant after
  such readjustment) to the Exercise Price and number of shares of Common Stock
  so purchasable that would then be in effect had the adjustment made upon the
  issuance, sale, distribution or granting of such Options or Convertible
  Securities been made based upon such changed purchase price, additional
  consideration or conversion rate, as the case may be, but only with respect to
  such Options and Convertible Securities as then remain outstanding.

            (j) Expiration of Options and Convertible Securities.  If, at any
                ------------------------------------------------             
  time after any adjustment to the number of shares of Common Stock purchasable
  upon the exercise of each Warrant shall have been made pursuant to paragraph
  (c) or (i) above or this paragraph (j), any Options or Convertible Securities
  shall have expired unexercised, the number of such shares so purchasable
  shall, upon such expiration, be readjusted and shall thereafter be such as
  they would have been had they been originally adjusted (or had the original
  adjustment not been required, as the case may be) as if (i) the only shares of
  Common Stock deemed to have been issued in connection with such Options or
  Convertible Securities were the shares of Common Stock, if any, actually
  issued or sold upon the exercise of such Options or Convertible Securities and
  (ii) such shares of Common Stock, if any, were issued or sold for the
  consideration actually received by the Company upon such exercise plus the
  aggregate consideration, if any, actually received by the Company for the
  issuance, sale, distribution or granting of all such Options or Convertible
  Securities, whether or not exercised; provided that no such readjustment shall
  have the effect of decreasing the number of such shares so purchasable by an
  amount (calculated by adjusting such decrease to account for all other
  adjustments made pursuant to this Section 13 following the date of the
  original adjustment referred to above) in excess of the amount of the
  adjustment initially made in respect of the issuance, sale, distribution or
  granting of such Options or Convertible Securities.

            (k) Other Adjustments.  In the event that at any time, as a result
                -----------------                                             
  of an adjustment made pursuant to this Section 13, the Holders shall become
  entitled to receive any securities of the Company other than shares of Common
  Stock, thereafter the number of such other securities so receivable upon
  exercise of the Warrants and the Exercise Price applicable to such exercise
  shall be

                                      16
<PAGE>
 
  subject to adjustment from time to time in a manner and on terms as nearly
  equivalent as practicable to the provisions with respect to the shares of
  Common Stock contained in this Section 13.

            (l) Adjustment in Number of Shares. Upon each adjustment of the
                ------------------------------                             
  Exercise Price pursuant to this Section 13 or upon the occurrence of any event
  or action which would require an adjustment of the Exercise Price pursuant to
  this Section 13 but for Section 13(h), each Warrant outstanding prior to the
  making of the adjustment in the Exercise Price shall thereafter evidence the
  right to receive upon payment of the adjusted Exercise Price that number of
  share of Common Stock obtained by dividing (i) the sum of the adjusted number
  of Warrant Shares issuable upon exercise of a Warrant by payment of the
  adjusted Exercise Price plus the Exercise Price prior to adjustment by (ii)
  the adjusted Exercise Price (without giving effect to the provisions of
  Section 13(h)).

            Irrespective of any adjustments in the Exercise Price or the number
  or kind of shares purchasable upon the exercise of the Warrants, Warrants
  theretofore or thereafter issued may continue to express the same price and
  number and kind of shares as are stated in the Warrants initially issuable
  pursuant to this Agreement.

            SECTION 14.  Statement on Warrants.  Irrespective of any adjustment
                         ---------------------                                 
  in the number or kind of shares issuable upon the exercise of the Warrants or
  the Exercise Price, Warrants theretofore or thereafter issued may continue to
  express the same number and kind of shares as are stated in the Warrants
  initially issuable pursuant to this Agreement.

            SECTION 15.  Fractional Interest.  The Company shall not be required
                         -------------------                                    
  to issue fractional shares of Common Stock on the exercise of Warrants.  If
  more than one Warrant shall be presented for exercise in full at the same time
  by the same Holder, the number of full shares of Common Stock which shall be
  issuable upon such exercise shall be computed on the basis of the aggregate
  number of shares of Common Stock acquirable on exercise of the Warrants so
  presented. If any fraction of a share of Common Stock would, except for the
  provisions of this Section, be issuable on the exercise of any Warrant (or
  specified portion thereof), the Company shall direct the Transfer Agent to pay
  an amount in cash calculated by it to equal the then current market price per
  share multiplied by such fraction computed to the nearest whole cent.  The
  Holders, by their acceptance of the Warrant Certificates, expressly waive any
  and all rights to receive any fraction of a share of Common Stock or a stock
  certificate representing a fraction of a share of Common Stock.

            SECTION 16.  Notices to Warrant Holders.  Upon any adjustment of the
                         --------------------------                             
  Exercise Price pursuant to Section 13, the Company shall promptly thereafter
  (i) cause to be filed with the Warrant Agent a certificate of a firm of
  independent public accountants of recognized standing selected by the Board of
  Directors of the Company (who may be the regular auditors of the Company)
  setting forth the Exercise Price after such adjustment and setting forth in
  reasonable detail the method of calculation and the facts upon which such
  calculations are based and setting forth the number of Warrant Shares (or
  portion thereof) issuable after such adjustment in the Exercise Price, upon
  exercise of a Warrant and payment of the adjusted Exercise Price, which
  certificate shall be conclusive evidence of the correctness of the matters set
  forth therein, and (ii) cause to be given to each of the registered Holders of
  the Warrant Certificates at his address appearing on the Warrant register
  written notice of such adjustments by first-class mail, postage prepaid.  The
  Warrant Agent shall be entitled to rely on the above-referenced accountant's
  certificate and shall be under no duty or responsibility with respect to any
  such certificate, except to exhibit the same from time to time to any Holder
  desiring an inspection

                                      17
<PAGE>
 
  thereof during reasonable business hours.  The Warrant Agent shall not at any
  time be under any duty or responsibility to any Holder to determine whether
  any facts exist that may require any adjustment of the number of shares of
  Common Stock or other stock or property issuable on exercise of the Warrants
  or the Exercise Price, or with respect to the nature or extent of any such
  adjustment when made, or with respect to the method employed in making such
  adjustment or the validity or value (or the kind or amount) of any shares of
  Common Stock or other stock or property which may be issuable on exercise of
  the Warrants.  The Warrant Agent shall not be responsible for any failure of
  the Company to make any cash payment or to issue, transfer or deliver any
  shares of Common Stock or stock certificates or other common stock or property
  upon the exercise of any Warrant.

            In case:

            (a) the Company shall authorize the issuance to all holders of 
     shares of Common Stock of rights, options or warrants to subscribe for or
     purchase shares of Common Stock or of any other subscription rights or
     warrants; or

            (b) the Company shall authorize the distribution to all holders of
     shares of Common Stock of evidences of its indebtedness or assets (other
     than cash dividends or cash distributions payable out of consolidated
     earnings or earned surplus or dividends payable in shares of Common Stock
     or distributions referred to in Section 13 hereof); or

            (c) of any consolidation or merger to which the Company is a party 
     and for which approval of any shareholders of the Company is required, or
     of the conveyance or transfer of the properties and assets of the Company
     substantially as an entirety, or of any reclassification or change of
     Common Stock issuable upon exercise of the Warrants (other than a change
     in par value, or from par value to no par value, or from no par value to
     par value, or as a result of a subdivision or combination), or a tender
     offer or exchange offer for shares of Common Stock; or

            (d) of the voluntary or involuntary dissolution, liquidation or 
     winding up of the Company; or

            (e) a Change of Control (as defined in the Indenture) occurs; or

            (f) the Company proposes to take any other action that would 
     require an adjustment of the Exercise Price or the number of Warrant
     Shares pursuant to Section 13;

  then the Company shall cause to be filed with the Warrant Agent and shall
  cause to be given to each of the registered Holders of the Warrant
  Certificates at such Holder's address appearing on the Warrant register, at
  least 20 days (or 10 days in any case specified in clauses (a) or (b) above)
  prior to the applicable record date hereinafter specified, or promptly in the
  case of events for which there is no record date, by first class mail, postage
  prepaid, a written notice stating (i) the date as of which the holders of
  record of shares of Common Stock to be entitled to receive any such rights,
  options, warrants or distribution are to be determined, or (ii) the initial
  expiration date set forth in any tender offer or exchange offer for shares of
  Common Stock, or (iii) the date on which any such consolidation, merger,
  conveyance, transfer, dissolution, liquidation or winding up or Change of
  Control is expected to become effective or consummated, and the date as of
  which it is expected that holders of record of shares of

                                      18
<PAGE>
 
  Common Stock shall be entitled to exchange such shares for securities or other
  property, if any, deliverable upon such reclassification, consolidation,
  merger, conveyance, transfer, dissolution, liquidation or winding up or Change
  of Control.  The failure to give the notice required by this Section 16 or any
  defect therein shall not affect the legality or validity of any distribution,
  right, option, warrant, consolidation, merger, conveyance, transfer,
  dissolution, liquidation or winding up, or Change of Control or the vote upon
  any action.  Nothing contained in this Agreement or in any of the Warrant
  Certificates shall be construed as conferring upon the Holders thereof the
  right to vote or to consent or to receive notice as shareholders in respect of
  the meetings of shareholders or the election of Directors of the Company or
  any other matter, or any rights whatsoever as shareholders of the Company.

            SECTION 17.  Merger, Consolidation or Change of Name of Warrant
                         --------------------------------------------------
  Agent.  Any corporation into which the Warrant Agent may be merged or with
  -----                                                                     
  which it may be consolidated, or any corporation resulting from any merger or
  consolidation to which the Warrant Agent shall be a party, or any corporation
  succeeding to the business of the Warrant Agent, shall be the successor to the
  Warrant Agent hereunder without the execution or filing of any paper or any
  further act on the part of any of the parties hereto, provided that such
  corporation would be eligible for appointment as a successor warrant agent
  under the provisions of Section 19.  Any such successor Warrant Agent shall
  promptly cause notice of its succession as Warrant Agent to be mailed (by
  first class mail, postage prepaid) to each Holder at such Holder's last
  address as shown on the register maintained by the Warrant Agent pursuant this
  Agreement.  In case at the time such successor to the Warrant Agent shall
  succeed to the agency created by this Agreement, and in case at that time any
  of the Warrant Certificates shall have been countersigned but not delivered,
  any such successor to the Warrant Agent may adopt the countersignature of the
  original Warrant Agent; and in case at that time any of the Warrant
  Certificates shall not have been countersigned, any successor to the Warrant
  Agent may countersign such Warrant Certificates either in the name of the
  predecessor Warrant Agent or in the name of the successor to the Warrant
  Agent; and in all such cases such Warrant Certificates shall have the full
  force and effect provided in the Warrant Certificates and in this Agreement.

            In case at any time the name of the Warrant Agent shall be changed
  and at such time any of the Warrant Certificates shall have been countersigned
  but not delivered, the Warrant Agent whose name has been changed may adopt the
  countersignature under its prior name, and in case at that time any of the
  Warrant Certificates shall not have been countersigned, the Warrant Agent may
  countersign such Warrant Certificates either in its prior name or in its
  changed name, and in all such cases such Warrant Certificates shall have the
  full force and effect provided in the Warrant Certificates and in this
  Agreement.

            SECTION 18.  Warrant Agent.  The Warrant Agent undertakes the duties
                         -------------                                          
  and obligations imposed by this Agreement upon the following terms and
  conditions, by all of which the Company and the Holders of Warrants, by their
  acceptance thereof, shall be bound:

            (a) The statements contained herein and in the Warrant Certificates
     shall be taken as statements of the Company and the Warrant Agent assumes
     no responsibility for the correctness of any of the same except such as
     describe the Warrant Agent or action taken or to be taken by it.  The
     Warrant Agent assumes no responsibility with respect to the distribution
     of the Warrant Certificates except as herein otherwise provided.

                                      19
<PAGE>
 
            (b) The Warrant Agent shall not be responsible for any failure of
     the Company to comply with any of the covenants contained in this
     Agreement or in the Warrant Certificates to be complied with by the
     Company.

            (c) The Warrant Agent may consult at any time with counsel
     satisfactory to it (who may be counsel for the Company) and the Warrant
     Agent shall incur no liability or responsibility to the Company or to any
     Holder of any Warrant Certificate in respect of any action taken, suffered
     or omitted by it hereunder in good faith and in accordance with the
     opinion or the advice of such counsel.

            (d) The Warrant Agent shall incur no liability or responsibility to
     the Company or to any Holder of any Warrant Certificate for any action
     taken in reliance on any Warrant Certificate, certificate of shares,
     notice, resolution, waiver, consent, order, certificate, or other paper,
     document or instrument believed by it to be genuine and to have been
     signed, sent or presented by the proper party or parties.

            (e) The Company agrees to pay to the Warrant Agent reasonable
     compensation for all services rendered by the Warrant Agent in the
     execution of this Agreement, to reimburse the Warrant Agent for all
     expenses, taxes and governmental charges and other charges of any kind and
     nature reasonably incurred by the Warrant Agent in the execution of this
     Agreement and to indemnify the Warrant Agent and save it harmless against
     any and all liabilities, including judgments, reasonable costs and counsel
     fees, for anything done or omitted by the Warrant Agent in the execution
     of this Agreement except as a result of its negligence or bad faith.

            (f) The Warrant Agent shall be under no obligation to institute any
     action, suit or legal proceeding or to take any other action likely to
     involve expense unless the Company or one or more Holders of Warrant
     Certificates shall furnish the Warrant Agent with reasonable security and
     indemnity for any costs and expenses which may be incurred, but this
     provision shall not affect the power of the Warrant Agent to take such
     action as it may consider proper, whether with or without any such
     security or indemnity.  All rights of action under this Agreement or under
     any of the Warrants may be enforced by the Warrant Agent without the
     possession of any of the Warrant Certificates or the production thereof at
     any trial or other proceeding relative thereto, and any such action, suit
     or proceeding instituted by the Warrant Agent shall be brought in its name
     as Warrant Agent and any recovery of judgment shall be for the ratable
     benefit of the Holders of the Warrants, as their respective rights or
     interests may appear.

            (g) The Warrant Agent, and any stockholder, director, officer or
     employee of it, may buy, sell or deal in any of the Warrants or other
     securities of the Company or become pecuniarily interested in any
     transaction in which the Company may be interested, or contract with or
     lend money to the Company or otherwise act as fully and freely as though
     it were not Warrant Agent under this Agreement.  Nothing herein shall
     preclude the Warrant Agent from acting in any other capacity for the
     Company or for any other legal entity.

            (h) The Warrant Agent shall act hereunder solely as agent for the
     Company, and its duties shall be determined solely by the provisions
     hereof. The Warrant

                                      20
<PAGE>
 
     Agent shall not be liable for anything which it may do or refrain from
     doing in connection with this Agreement except for its own negligence or
     bad faith.

            (i) The Warrant Agent shall not at any time be under any duty or
     responsibility to any Holder of any Warrant Certificate to make or cause
     to be made any adjustment of the Exercise Price or number of the Warrant
     Shares or other securities or property deliverable as provided in this
     Agreement, or to determine whether any facts exist which may require any
     of such adjustments, or with respect to the nature or extent of any such
     adjustments, when made, or with respect to the method employed in making
     the same.  The Warrant Agent shall not be accountable with respect to the
     validity or value or the kind or amount of any Warrant Shares or of any
     securities or property which may at any time be issued or delivered upon
     the exercise of any Warrant or with respect to whether any such Warrant
     Shares or other securities will when issued be validly issued and fully
     paid and nonassessable, and makes no representation with respect thereto.

            SECTION 19.  Resignation and Removal of Warrant Agent; Appointment
                         -----------------------------------------------------
  of Successor.  No resignation or removal of the Warrant Agent and no
  ------------                                                        
  appointment of a successor warrant agent shall become effective until the
  acceptance of appointment by the successor warrant agent as provided herein.
  The Warrant Agent may resign its duties and be discharged from all further
  duties and liability hereunder (except liability arising as a result of the
  Warrant Agent's own negligence of willful misconduct) after giving written
  notice to the Company.  The Company may remove the Warrant Agent upon written
  notice, and the Warrant Agent shall thereupon in like manner be discharged
  from all further duties and liabilities hereunder, except as aforesaid.  The
  Warrant Agent shall, at the Company's expense, cause to be mailed (by first
  class mail, postage prepaid) to each Holder of a Warrant at his last address
  as shown on the register of the Company maintained by the Warrant Agent a copy
  of said notice of resignation or notice of removal, as the case may be.  Upon
  such resignation or removal, the Company shall appoint in writing a new
  warrant agent.  If the Company shall fail to make such appointment within a
  period of 30 days after it has been notified in writing of such resignation by
  the resigning Warrant Agent or after such removal, then the resigning Warrant
  Agent or the Holder of any Warrant may apply to any court of competent
  jurisdiction for the appointment of a new warrant agent.  Any new warrant
  agent, whether appointed by the Company or by such a court, shall be a
  corporation doing business under the laws of the United States or any state
  thereof, in good standing and having a combined capital and surplus of not
  less than $50,000,000.  The combined capital and surplus of any such new
  warrant agent shall be deemed to be the combined capital and surplus as set
  forth in the most recent annual report of its condition published by such
  warrant agent prior to its appointment, provided that such reports are
  published at least annually pursuant to law or to the requirements of a
  federal or state supervising or examining authority.  After acceptance in
  writing of such appointment by the new warrant agent, it shall be vested with
  the same powers, rights, duties and responsibilities as if it had been
  originally named herein as the Warrant Agent, without any further assurance,
  conveyance, act or deed; but if for any reason it shall be necessary or
  expedient to execute and deliver any further assurance, conveyance, act or
  deed, the same shall be done at the expense of the Company and shall be
  legally and validly executed and delivered by the resigning or removed Warrant
  Agent.  Not later than the effective date of any such appointment, the Company
  shall give notice thereof to the resigning or removed Warrant Agent.  Failure
  to give any notice provided for in this Section, however, or any defect
  therein, shall not affect the legality or validity of the resignation of the
  Warrant Agent or the appointment of a new warrant agent, as the case may be.

            SECTION 20.  Registration.  The Company and the Warrant Agent
                         ------------                                    
  acknowledge that Holders shall have the registration rights set forth in the
  Warrant Registration Rights Agreement.

             SECTION 21.  Reports.
                          ------- 

            (a) So long as any of the Warrants remain outstanding, and to the
  extent the Company is required to send such documents to the holders of its
  outstanding Common Stock, whether or not required by the rules and regulations
  of the Securities and Exchange Commission (the "Commission"), the Company
  shall furnish to the Holders of the Warrants (i) all quarterly and annual
  financial information that would be required to be contained in a filing with
  the Commission on Forms 10-Q and 10-K if the Company were required to file
  such Forms, including a "Management's Discussion and Analysis of Financial
  Condition and Results of Operations" and, with respect to the annual
  information only, a report thereon by the Company's certified independent
  accountants; (ii) all current reports that would be required to be filed with
  the Commission on Form 8-K if the Company were required to file such reports;
  and (iii) on a quarterly basis, certain financial information and operating
  data with respect to each Subsidiary (as defined in the Indenture) and Joint
  Venture (as defined in the Indenture) engaged in a Telecommunications Business
  (as defined in the Indenture), in the form specified by Schedule __ of the
  Indenture.  In addition, whether or not required by the rules and regulations
  of the Commission, the Company will file a copy of all such information and
  reports with the Commission for public availability (unless the Commission
  will not accept such a filing) and make such information available to
  securities analysts and prospective investors upon request.

            (b) The Company shall provide the Warrant Agent with a sufficient
  number of copies of all SEC Reports that the Warrant Agent may be required to
  deliver to the Holders of the Warrants under this Section 21.

            SECTION 22.  Rule 144A.  The Company hereby agrees with each Holder,

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

            SECTION 23.  Notices to Company and Warrant Agent. Any notice or

                         --------------------------                       
  Warrant Agent may from time to time supplement or amend this Agreement without
  the approval of any Holders of Warrant Certificates in order to cure any
  ambiguity or to correct or supplement any provision contained herein which may
  be defective or inconsistent with any other provision herein, or to make any
  other provisions in regard to matters or questions arising hereunder which the
  Company and the Warrant Agent may deem necessary or desirable and which shall
  not in any way adversely affect the interests of the Holders of Warrant
  Certificates.  Any amendment or supplement to this Agreement that has a
  material adverse effect on the interests of Holders shall require the written
  consent of Holders representing a majority of the then outstanding Warrants.
  The consent of each Holder of a Warrant affected shall be required for any
  amendment pursuant to which the Exercise Price would be increased or the
  number of Warrant Shares purchasable upon  exercise of Warrants would be
  decreased.  The Warrant Agent shall be entitled to receive and, subject to

  and opinion of counsel as conclusive evidence that any such amendment or
  supplement is authorized or permitted hereunder, that it is not inconsistent

  consent of the Warrant Agent or the Holder of any other Warrant, may, on such
  Holder's own behalf and for such Holder's own benefit, enforce, and may
  institute and maintain any suit, action or proceeding against the Company
  suitable to enforce, or otherwise in respect of, such Holder's rights
  hereunder, including the right to exercise, exchange or surrender for purchase
  such Holder's Warrants in the manner provided in this Agreement.

SECTION 2.     SECURITIES SUBJECT TO THIS AGREEMENT

     (a) Registrable Securities.  The securities entitled to the benefits of
         ----------------------                                             
this Agreement are the Registrable Securities.


                                       2
<PAGE>
 
     (b) Holders of Registrable Securities.  A Person is deemed to be a Holder
         ---------------------------------                                    
of Registrable Securities whenever such Person owns Registrable Securities or
has the right to acquire such Registrable Securities, whether or not such
acquisition has actually been effected and disregarding any legal restrictions
upon the exercise of such right.


SECTION 3.    SHELF REGISTRATION

     (a)  The Company shall file a "shelf" registration with respect to all
Registrable Securities on any appropriate form pursuant to Rule 415 (or similar
rule that may be adopted by the Commission) under the Act (the "Shelf
                                                                -----
Registration") (i) covering resales by the Holders of the Warrants, on or prior
- ------------                                                                   
to October 1, 1996 and (ii) covering the issuance of the Warrant Shares by the
Company upon exercise, or if such issuance is not then permitted to be
registered by applicable rule or policy of the Commission, covering resales of
the Warrant Shares, on or prior to January 1, 1997, and shall use its best
efforts to have such Shelf Registration declared effective by the Commission on
or prior to 90 days after the dates specified for such filings.  Notwithstanding
the foregoing, the Company shall not be required to file such Shelf Registration
on or prior to the consummation of the Exchange Offer; provided that, in the
event the Exchange Offer is consummated later than the filing time required by
the preceding sentence for each Shelf Registration, the Company shall file such
Shelf Registration(s) within 30 days after the date of the consummation of the
Exchange Offer.

     (b)  If the Holders of a majority in aggregate principal amount of the
Registrable Securities to be registered in the Shelf Registration so elect, an
offering of Registrable Securities pursuant to the Shelf Registration may be
effected in the form of an underwritten offering.  In such event, and if the
managing underwriters advise the Company and the Holders of such Registrable
Securities in writing that in their opinion the amount of Registrable Securities
proposed to be sold in such offering exceeds the amount of Registrable
Securities which can be sold in such offering, there shall be included in such
underwritten offering the amount of such Registrable Securities which in the
opinion of such underwriters can be sold, and such amount shall be allocated pro
rata among the Holders of such Registrable Securities on the basis of the
principal amount of Registrable Securities requested to be included by such
Holders.  The Holders of the Registrable Securities to be registered shall pay
all underwriting discounts and commissions of such underwriters.

     (c)  If any of the Registrable Securities covered by the Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will administer the offering will be
selected by the Holders of a majority in aggregate principal amount of such
Registrable Securities included in such offering; provided that such investment
                                                  --------                     
bank or manager shall be reasonably satisfactory to the Company.

     (d)  The Company shall use its best efforts to keep the Shelf Registration
continuously effective until October 1, 1999 for the Warrants and until January
1, 2000 for the Warrant Shares or such shorter period that will terminate when
all the Registrable Securities covered by the Shelf Registration have been sold
pursuant to the terms of the Shelf Registration.

     The Company further agrees to use its best efforts to prevent the happening
of any event that would cause the Registration Statement pursuant to Section 3
hereof to contain a material misstatement



                                       3
<PAGE>
 
or omission or to be not effective and usable for resale of the Registrable
Securities during the period that such Registration Statement is required to be
effective and usable.

     (e)  Each Holder of Registrable Securities whose Registrable Securities are
covered by a Registration Statement filed pursuant to this Section 3 agrees, if
requested by the managing underwriters in an underwritten offering, not to
effect any public sale or distribution of securities of the Company of the same
class as any Securities included in such Registration Statement, including a
sale pursuant to Rule 144 under the Act (except as part of such underwritten
registration), during the 10-day period prior to, and during the 90-day period
beginning on, the closing date of each underwritten offering made pursuant to
such Registration Statement, to the extent timely notified in writing by the
Company or the managing underwriters; provided that each Holder of Registrable
Securities shall be subject to the hold-back restrictions of this Section 3(e)
only once during the term of this Agreement.

     The foregoing provisions shall not apply to any Holder of Registrable
Securities if such Holder is prevented by applicable statute or regulation from
entering into any such agreement; provided that any such Holder shall undertake,
in its request to participate in any such underwritten offering, not to effect
any public sale or distribution of any applicable class of Registrable
Securities commencing on the date of sale of such applicable class of
Registrable Securities unless it has provided 45 days prior written notice of
such sale or distribution to the underwriter or underwriters.


SECTION 4.    LIQUIDATED DAMAGES

     If the Registration Statement:  (i) is not filed with the Commission on or
prior to the date specified for such filing in Section 3(a) hereof; (ii) has not
been declared effective by the Commission pursuant to Section 3(a) hereof; or
(iii) following the date such Registration Statement is declared effective by
the Commission, shall cease to be effective without being restored to
effectiveness by amendment or otherwise within 30 business days, (each such
event referred to in clauses (i) through (iii), a "Shelf Registration Default")
                                                   --------------------------  
to the extent permitted by applicable law, the Company shall pay as liquidated
damages and not as a penalty to each Holder during the first 90-day period
immediately following the occurrence, and during the continuance of such Shelf
Registration Default, an amount equal to $.0025 per week per Warrant (or per
such number of Warrant Shares then issuable upon exercise of or in respect of a
Warrant) held by such Holder for each week or pro rata for a portion of each
week thereof that the Shelf Registration Default continues.  To the extent
permitted by applicable law, the amount of the liquidated damages will increase
by an additional $.0025 per week per Warrant (or per such number of Warrant
Shares then issuable upon exercise of or in respect of a Warrant) with respect
to each subsequent 90-day period until all Shelf Registration Defaults have been
cured, up to a maximum amount of liquidated damages of $.0125 per week per
Warrant (or per such number of Warrant Shares then issuable upon exercise of or
in respect of a Warrant).

     All accrued liquidated damages shall be paid to record Holders by the
Company by wire transfer of immediately available funds, or by mailing a federal
funds check, on each Interest Payment Date (as defined in the Indenture).  All
obligations of the Company set forth in the preceding paragraph that are
outstanding with respect to any Registrable Security at the time such security
has been effectively registered under the Act shall survive until such time as
all such obligations with respect to such security have been satisfied in full.

SECTION 5.    REGISTRATION PROCEDURES

     (a)  General Provisions.  In connection with the Company's registration
          -------------------                                               
obligations pursuant to Section 3 hereof, the Company will use its best efforts
to effect such registration to permit the sale of such Registrable Securities in
accordance with the intended method or methods of disposition thereof, and
pursuant thereto the Company will as expeditiously as possible:

          (1)  use its best efforts to keep such Registration Statement
     continuously effective and provide or incorporate by reference all
     requisite financial statements for the period specified in Section 3 of
     this Agreement. Upon the occurrence of any event that would cause any such
     Registration Statement or the Prospectus contained therein (A) to contain a
     material misstatement or omission or (B) not to be effective and usable for
     resale of Registrable Securities during the period required by this
     Agreement, the Company shall file promptly an appropriate amendment to such
     Registration Statement or file appropriate documents that will be so
     incorporated by reference, (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;

          (2) 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 period set forth in
     Section 3(d) hereof; 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 comply in all material respects 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; the Company shall not be deemed to have used its best
     efforts to keep a Registration Statement effective during the applicable
     period if it voluntarily takes any action that would result in selling
     Holders of the Registrable Securities covered thereby not being able to
     sell such Registrable Securities during that period unless such action is
     required under applicable law, provided that the foregoing shall not apply
                                    --------
     to actions taken by the Company in good faith and for valid business
     reasons, including without limitation the acquisition or divestiture of
     assets, so long as the Company promptly thereafter complies with the
     requirements of clause (14) below, if applicable;

          (3)  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 Registrable 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



                                       5
<PAGE>
 
     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 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 Registrable 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;

          (4)   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 and the
     Company will not file or will correct 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 Registrable 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;

          (5)  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;

          (6)  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 (6) agrees in writing to maintain the confidentiality of
     such information to the extent such information is not in the public
     domain;

          (7)  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 Registrable Securities, information with respect to
     the principal amount of Registrable Securities being sold to such



                                       6
<PAGE>
 
     underwriter(s), the purchase price being paid therefor and any other terms
     of the offering of the Registrable 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;

          (8)  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);

          (9)  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 Registrable Securities covered by the
     Prospectus or any amendment or supplement thereto;

          (10)  enter into such agreements (including, unless not required
     pursuant to Section 3 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 Registrable Securities pursuant to any Registration Statement
     contemplated by this Agreement as may be reasonably requested by any Holder
     of Registrable 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, if any,
          upon the effectiveness of the Registration Statement:

                    (1)  a certificate, dated the date of effectiveness of the
               Registration Statement, signed by (x) the President and (y) any
               Vice President, the Secretary or an Assistant Secretary 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;

                    (2)  an opinion, dated the date of effectiveness of the
               Registration Statement, of counsel for the Company, covering (i)
               due authorization and enforceability of the Warrants, (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 provided to such
               counsel by officers and other representatives



                                       7
<PAGE>
 
               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 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, 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 Registration Statement, 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 Registration Statement the indemnification provisions
          and procedures of Section 7 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 (10), 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;

          (11)  prior to any public offering of Registrable Securities,
     cooperate with the selling Holders, the underwriter(s), if any, and their
     respective counsel in connection with the registration and qualification of
     the Registrable Securities under the securities or Blue Sky 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 Registrable Securities covered
     by the applicable Registration Statement; provided that the Company



                                       8
<PAGE>
 
     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;

          (12)  in connection with any sale of Registrable 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
     Registrable Securities to be sold and not bearing any restrictive legends;
     and to register such Registrable 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 Registrable Securities;

          (13)  use its best efforts to cause the Registrable 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 Registrable Securities, subject to the proviso
     contained in clause (11) above;

          (14)  if any fact or event contemplated by clause (2) 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 Registrable 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;

          (15)  provide a CUSIP number for all Registrable Securities not later
     than the effective date of a Registration Statement covering such
     Registrable Securities and provide the Trustee under the Indenture with
     printed certificates for the Registrable Securities which are in a form
     eligible for deposit with the Depository Trust Company;

          (16)  cooperate and assist in any filings required to be made with the
     NASD and in the performance of any due diligence investigation by any
     underwriter (including any "qualified independent underwriter") that is
     required to be retained in accordance with the rules and regulations of the
     NASD, and use 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 Registrable Securities to
     consummate the disposition of such Registrable Securities;

          (17)  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);




                                       9
<PAGE>
 
          (18)  cause all Registrable 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 principal amount of Registrable
     Securities or the managing underwriter(s), if any;

          (19)  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

          (20)  if the registration is a registration in which securities of the
     Company are sold to an underwriter for reoffering to the public, obtain a
     customary comfort letter, dated as of the date of effectiveness of each
     Registration Statement, addressed to the Board of Directors of the Company
     from the Company's independent accountants, in the customary form and
     covering matters of the type customarily covered in comfort letters to
     boards of directors in underwritten offerings.

     (b)  Restrictions on Holders.  Each Holder agrees by acquisition of a
          -----------------------                                         
Registrable Security that, upon receipt of any notice from the Company of the
existence of any fact of the kind described in Section 5(a)(3)(D) hereof, such
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to the applicable Registration Statement until such Holder's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section
5(a)(14) 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 permanent file copies
then in such Holder's possession, of the Prospectus covering such Registrable
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 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 5(a)(3)(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 5(a)(14) hereof or shall have
received the Advice.


SECTION 6.    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 by any Holder
with the NASD (and, if applicable, the fees and expenses 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, without limitation, expenses of printing or engraving certificates
for the Registrable Securities in a form eligible for deposit with the
Depositary Trust Company and printing of Prospectuses), messenger and delivery
services and telephone; (iv) all fees and disbursements of counsel for the
Company and the Holders of Transfer Restricted Securities; (v) all application
and filing fees in connection with listing the Registrable Securities on a
national exchange or automated quotation system



                                      10
<PAGE>
 
pursuant to the requirements hereof; 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 each Registration Statement required hereunder, the
Company will reimburse the Holders of Registrable Securities being registered
pursuant to such Registration Statement for the fees and disbursements of not
more than one counsel chosen by the Holders of a majority of the principal
amount of such Registrable Securities, or more than one, if, in the reasonable
judgment of counsel for the Holders and counsel for the Company, a conflict
exists among such Holders. Notwithstanding the provisions of this Section 6,
each Holder of Registrable Securities shall pay all registration expenses to the
extent required by applicable law.


SECTION 7.    INDEMNIFICATION

     (a) The Company and its Subsidiaries, jointly and severally, agree 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 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, 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 Warrants 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 Warrants 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)



                                      11
<PAGE>
 
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 Registrable Securities 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 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 7 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.  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



                                      12
<PAGE>
 
parties in each jurisdiction in which any claim or action is brought; provided
that the indemnifying party shall be liable for separate counsel for any
indemnified party in a jurisdiction, if counsel to the indemnified parties shall
have reasonably concluded that there may be defenses available to such
indemnified party that are different from or additional to those available to
those available to one or more of the other indemnified parties and that
separate counsel for such indemnified party is prudent under the circumstances.
Anything in this subsection to the contrary notwithstanding, an indemnifying
party shall not be liable for any settlement of any claim or action effected
without its prior written consent; provided, that such consent was not
unreasonably withheld.

     (d) In order to provide for contribution in circumstances in which the
indemnification provided for in this Section 7 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 Registrable Securities and any such
Holder from its sale of Registrable Securities 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 7,
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 of the Registrable Securities (net of discounts but before
deducting expenses) received by the Company and (y) the total proceeds received
by such Holder upon its sale of Registrable Securities 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 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 7 were determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to above.  Notwithstanding
the provisions of this Section 7, (i) 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 Registrable Securities exceeds
the sum of (A) the amount paid by such Holder for such Registrable Security 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 7, (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




                                      13
<PAGE>
 
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 7(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 7, notify such party or parties from whom contribution may be
sought, but the failure to so notify such party or parties shall not relieve the
party or parties from whom contribution may be sought from any obligation it or
they may have under this Section 7 or otherwise.  No party shall be liable for
contribution with respect to any action or claim settled without its prior
written consent; provided, however, that such written consent was not
unreasonably withheld.


SECTION 8.    RULE 144A

     The Company hereby agrees with each Holder, for so long as any Registrable
Securities remain outstanding, to make available, upon request of any Holder of
Registrable Securities, to any Holder or beneficial owner of Registrable
Securities in connection with any sale thereof and any prospective purchaser of
such Registrable 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 Registrable Securities pursuant to Rule 144A.


SECTION 9.    MISCELLANEOUS

     (a) Remedies.  Each Holder of Registrable Securities, in addition to being
         ---------                                                             
entitled to exercise all rights provided herein, and as provided in the Purchase
Agreement and the Warrant Agreement and granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement.  The Company agrees that monetary damages 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 of Registrable Securities in
this Agreement or otherwise conflicts with the provisions hereof. The Company
has not previously entered into any agreement granting any registration rights
of its securities to any Person except as set forth in Schedule I hereto.  The
rights granted to the Holders of Registrable Securities 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 other 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 Registrable Securities.  The Company will not
         -------------------------------------------------                      
take any action, or permit any change to occur, with respect to the Registrable
Securities which would (i) adversely affect the ability of any of the Holders of
Registrable Securities to include such Registrable Securities in a registration
undertaken pursuant to this Agreement or (ii) materially adversely affect the
marketability of the Registrable Securities in any such registration.




                                      14

     (d) Amendments and Waivers.  The provisions of this Agreement, including
         -----------------------                                             
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to 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 Registrable Securities.  Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders of Registrable Securities whose
securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other Holders of Registrable
Securities may be given by the Holders of at least a majority of the Registrable
Securities being sold.

     (e) Notices.  All notices and other communications provided for or
         --------

Notes") that have been registered under the Securities Act of 1933, as amended
(the "Securities Act"), pursuant to a Registration Statement of which the
Prospectus constitutes a part, for each $1,000 principal amount of its
outstanding 13% Senior Discount Notes due 2003 (the "Old Notes"), upon the terms

Ladies and Gentlemen:

     Subject to the terms of the Exchange Offer, the undersigned hereby tenders
to the Issuer the principal amount of Old Notes indicated above.  Subject to and
effective upon the acceptance

                                      -4-
<PAGE>
 
for exchange of the principal amount of Old Notes tendered in accordance with
this Letter of Transmittal, the undersigned sells, assigns and transfers to, or
upon the order of, the Issuer all right, title and interest in and to the Old
Notes tendered hereby. The undersigned hereby irrevocably constitutes and
appoints the Exchange Agent and its agent and attorney-in-fact (with full
knowledge that the Exchange Agent also acts as the agent of the Issuer and as
Trustee under the Indenture for the Old Notes and the New Notes) with respect to
the tendered Old Notes with full power of substitution to (i) deliver
certificates for such Old Notes to the Issuer, or transfer ownership of such Old
Notes on the account books maintained by DTC, together, in either such case,
with all accompanying evidences of transfer and authenticity to, or upon the
order of, the Issuer and (ii) present such Old Notes for transfer on the books
of the Issuer and receive all benefits and otherwise exercise all rights of
beneficial ownership of such Old Notes, all in accordance with the terms of the
Exchange Offer. The power of attorney granted in this paragraph shall be deemed
irrevocable and coupled with an interest.

     The undersigned hereby represents and warrants that he or she has full
power and authority to tender, sell, assign and transfer the Old Notes tendered
hereby and that the Issuer will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim when the same are acquired by the Issuer.  The
undersigned also acknowledges that this Exchange Offer is being made in reliance
upon an interpretation by the staff of the Securities and Exchange Commission
that the New Notes issued in exchange for the Old Notes pursuant to the Exchange
Offer may be offered for resale, resold and otherwise transferred by the holders
thereof (other than any such holder that is an "affiliate" of the Issuer within
the meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such New Notes are acquired in the ordinary course of such holders'
business and such holders have no arrangement with any person to participate in
the distribution of such New Notes. The undersigned acknowledges that if he or
she is participating in the Exchange Offer for the purpose of distributing the
New Notes, the undersigned must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction.  If the undersigned is not a broker-dealer, the undersigned
represents that it is not engaged in, and does not intend to engage in, a
distribution of the New Notes.  If the undersigned is a broker-dealer that will
receive New Notes for its own account in exchange for Old Notes and the
undersigned represents that such Old Notes were acquired as a result of market-
making activities or other trading activities and acknowledges that it will
deliver a prospectus in connection with any resale of such New Notes, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     The undersigned represents that (i) the New Notes acquired pursuant to the
Exchange Offer are being obtained in the ordinary course of such Holder's
business, (ii) such Holder has no arrangements with any person to participate in
the distribution of such New Notes and (iii) such Holder is not an "affiliate,"
as defined under Rule 405 of the Securities Act, of the Issuer or, if such
Holder is an affiliate, that such Holder will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Issuer to be necessary or
desirable to complete the assignment and transfer of the Old Notes tendered
hereby.

     For purposes of the Exchange Offer, the Issuer shall be deemed to have
accepted validly tendered Old Notes when, as and if the Issuer has given oral or
written notice thereof to the Exchange Agent.  If any tendered Old Notes are not
accepted for exchange pursuant to the Exchange Offer for any reason,
certificates for any such unaccepted Old Notes will be terminated (except as
noted below with respect to tenders through DTC), without expense, to the
undersigned at the address shown below or at a different address shown below or
at a different address as may be indicated under "Special Issuance Instructions"
as soon  as practicable following the Expiration Date.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned and every obligation under this Letter of Transmittal shall be
binding upon the undersigned's heirs, personal representatives, successors and
assigns.

     The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer-Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Issuer upon the terms and
subject to the conditions of the Exchange Offer.

     Unless otherwise indicated under "Special Issuance Instructions," please
issue the certificates representing the New Notes issued in exchange for the Old
Notes accepted for exchange and return any Old Notes not tendered or not
exchanged, in the name(s) of the undersigned (or in such event in the case of
Old Notes tendered by DTC, by credit to the account at DTC).  Similarly, unless
otherwise indicated under "Special Delivery Instructions," please send the
certificates representing the New Notes issued in exchange for the Old Notes
accepted for exchange and any certificates for Old Notes not tendered or not
exchanged (and accompanying documents, as appropriate) to the undersigned at the
address shown below the undersigned's signatures, unless, in either event,
tender is being made through DTC.  In the event that both "Special Issuance
Instructions" and "Special Delivery Instructions" are completed, please issue
the certificates representing the New Notes issued in exchange for the Old Notes
accepted for exchange and return any Old Notes not tendered or not exchanged in
the name(s) of, and send said certificates to, the person(s) so indicated.  The
undersigned recognizes that the Issuer has no obligation pursuant to the
"Special Issuance Instructions" and "Special Delivery Instructions" to transfer
any Old Notes from the name of the registered holder(s) thereof if the Issuer
does not accept for exchange any of the Old Notes so tendered.

                                 INSTRUCTIONS

                   Forming Part of the Terms and Conditions
                             of the Exchange Offer

     1.  Delivery of this Letter of Transmittal and Old Notes.  The certificates
for the tendered Old Notes (or a confirmation of a book-entry into the Exchange
Agent's account at DTC of all Old Notes delivered electronically), as well as a
properly completed and duly executed copy of this Letter of Transmittal or
facsimile hereof and any other documents required by this Letter of Transmittal
must be received by the Exchange Agent at its address set forth herein prior to
5:00 p.m., New York City time, on the Expiration Date.  The method of delivery
of the tendered Old Notes, this Letter of Transmittal and all other required
documents to the Exchange Agent is at the election and risk of the Holder and,
except as otherwise provided below, the delivery will be deemed made only when
actually received by the Exchange Agent.  Instead of delivery by mail, it is
recommended that the Holder use an overnight or hand delivery service.  In all
cases, sufficient time should be allowed to assume timely delivery.  No Letter
of Transmittal or Old Notes should be sent to the Issuer.

     Holders who wish to tender their Old notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes, this Letter of
Transmittal or any other documents required hereby to the Exchange Agent prior
to the Expiration Date must tender their Old Notes and follow the guaranteed
delivery procedures set forth in the Prospectus. Pursuant to such procedures:
(i) such tender must be made by or through an Eligible Institution; (ii) prior
to the Expiration Date, the Exchange Agent must have received from the Eligible
Institution a properly completed and duly executed Notice of Guaranteed Delivery
(by facsimile transmission, mail or hand delivery) setting forth the name and
address of the Holder of the Old Notes, the certificate number or numbers of
such Old Notes and the principal amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that, within five business days
after the Expiration Date, this Letter of Transmittal (or facsimile thereof)
together with the certificate(s) representing the Old Notes (or a confirmation
of electronic delivery of book-entry delivery into the Exchange Agent's account
at DTC) and any of the required documents will be deposited by the Eligible
Institution with the Exchange Agent; and (iii) such properly completed and
executed Letter of Transmittal (or facsimile hereof), as well as all other
documents required by this Letter of Transmittal and the certificate(s)
representing all tendered Old Notes in proper form for transfer (or a
confirmation of electronic mail delivery of book-entry delivery into the
Exchange Agent's account at DTC), must be received by the Exchange Agent within
five business days after the Expiration Date, all as provided in the Prospectus
under the caption "Guaranteed Delivery Procedures."  Any Holder of Old Notes who
wishes to tender his Old Notes pursuant to the guaranteed delivery procedures
described above must ensure that the Exchange Agent receives the Notice of
Guaranteed Delivery prior to 5:00 p.m., New York City time, on the Expiration
Date.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Notes will be determined by
the Issuer in its sole discretion, which determination will be final and
binding.  The Issuer reserves the absolute right

                                      -9-
<PAGE>
 
to reject any and all Old Notes not properly tendered or any Old Notes the
Issuer's acceptance of which would, in the opinion of counsel for the Issuer, be
unlawful. The Issuer also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes. The Issuer's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
this Letter of Transmittal) will be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
must be cured within such time as the Issuer shall determine. Neither the
Issuer, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them incur any liability for failure to give such notification.
Tenders of Old Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Notes received by the Exchange
Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned without cost by
the Exchange Agent to the tendering Holders of Old Notes, unless otherwise
provided in this Letter of Transmittal, as soon as practicable following the
Expiration Date.

     2.  Partial Tenders.  Tenders of Old Notes will be accepted in all
denominations of $1,000 and integral multiples in excess thereof.  If less than
the entire principal amount of any Old Notes is tendered, the tendering Holders
should fill in the principal amount tendered in the third column of the chart
entitled "Description of Old Notes."  The entire principal amount of Old Notes
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise indicated.  If the entire principal amount of all Old Notes is not
tendered, Old Notes for the principal amount of Old Notes delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
If the entire principal amount of all Old Notes is not tendered, Old Notes for
the principal amount of Old Notes not tendered and a certificate or certificates
representing New Notes issued in exchange of any Old Notes accepted will be sent
to the Holder at his or her registered address, unless a different address is
provided in the appropriate box on this Letter of Transmittal or unless tender
is made through DTC, promptly after the Old Notes are accepted for exchange.

     3.  Signatures on the Letter of Transmittal;  Bond Powers and Endorsements;
Guarantee of Signatures.  If this Letter of Transmittal (or facsimile hereof) is
signed by the registered Holder(s) of the Old Notes tendered hereby, the
signature must correspond with the name(s) as written on the face of the Old
Notes without alteration, enlargement or any change whatsoever.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder(s) of Old Notes tendered and the certificate(s) for New Notes
issued in exchange thereof is to be issued (or any untendered principal amount
of Old Notes is to be reissued) to the registered Holder, such Holder need not
and should not endorse any tendered Old Note, nor provide a separate bond power.
In any other case, such Holder must either properly endorse the Old Notes
tendered or transmit a properly completed separate bond power with this Letter
of Transmittal, with the signatures on the endorsement or bond power guaranteed
by an Eligible Institution.

     If this Letter of Transmittal (or facsimile hereof) or any Old Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of

                                      -10-
<PAGE>
 
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Issuer,
evidence satisfactory to the Issuer of their authority so to act must be
submitted with this Letter of Transmittal.

     Endorsements on Old Notes or signatures on bond powers required by this
Instruction 3 must be guaranteed by an Eligible Institution.

     Signatures on this Letter of Transmittal (or facsimile hereof) must be
guaranteed by an Eligible Institution unless the Old Notes tendered pursuant
thereto are tendered (i) by a registered Holder (including any participant in
DTC whose name appears on a security position listing as the owner of Old Notes)
who has not completed the box set forth herein entitled "Special Issuance
Instructions" or the box entitled "Special Delivery Instructions" or (ii) for
the account of an Eligible Institution.

     4.  Special Issuance and Delivery Instructions.  Tendering Holders should
indicate, in the applicable spaces, the name and address to which New Notes or
substitute Old Notes for principal amounts not tendered or not accepted for
exchange are to be issued or sent, if different from the name and address of the
person signing this Letter of Transmittal (or in the case of tender of the Old
Notes through DTC, if different from DTC).  In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.

     5.  Transfer Taxes.  The Issuer will pay all transfer taxes, if any,
applicable to the exchange of Old Notes pursuant to the Exchange Offer.  If,
however, certificates representing New Notes or Old Notes for principal amounts
not tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered Holder
of the Old Notes tendered hereby, or if tendered Old Notes are registered in the
name of any person other than the person signing this Letter of Transmittal, or
if a transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered Holder or any other person) will be payable
by the tendering Holder.  If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with this Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering Holder

     Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.

     6.  Waiver of Conditions.  The Issuer reserves the absolute right to amend,
waive or modify specified conditions in the Exchange Offer in the case of any
Old Notes tendered.

     7.  Mutilated, Lost, Stolen or Destroyed Old Notes.  Any tendering Holder
whose Old Notes have been mutilated, lost, stolen or destroyed should contact
the Exchange Agent at the address indicated herein for further instruction.

     8.  Requests for Assistance or Additional Copies.  Questions and requests
for assistance and requests for additional copies of the Prospectus or this
Letter of Transmittal may

                                      -11-

be directed to the Exchange Agent at the address specified in the Prospectus.
Holders may also contact their broker, dealer, commercial bank, trust company or
other nominee for assistance concerning the Exchange Offer.
